Description

food storage

technical field

The present invention relates to a food storage including a refrigerator, and more particularly to a food storage capable of decomposing pesticides remaining in food.

Background technique

In recent years, consumers have been feeling uneasy about food safety, especially about pesticide residues in food. About 90% of consumers feel uneasy. This is the result of a public opinion survey.

In order to ensure the safety of pesticide residues, regulations such as the Food Sanitation Law, which restricts the use of pesticides by farmers and limits the amount of residues from the perspective of human health, are enacted. However, in the inspection of pesticide residues carried out by the Ministry of Labor every year, There is always the fact that so-called illegal agricultural products remain in excess of the prescribed amount. Pesticide residues with a high detection rate are mainly pesticides imported from overseas and used for long-term storage. Among them, there are also many pesticides that are banned from use in Japan.

In the actual situation of such residual pesticides, it is considered that a device for removing residual pesticides is very much needed in order for consumers to live a food life with peace of mind.

Conventionally, there exists a refrigerator provided with the function of an ozone generator (for example, refer patent document 1).

FIG. 6 is a diagram showing an apparatus of refrigerator 1 including a conventional ozone generator described in Patent Document 1. As shown in FIG.

As shown in the figure, the refrigerator 1 includes a refrigerator compartment 3, a vegetable refrigerator compartment 4, a switch compartment 5, a freezer compartment 6, a hinge type refrigerator door 7, a drawer type vegetable compartment door 8, a switch compartment door 9, and a freezer compartment. chamber door10. In addition, a deodorizing and antibacterial device (corresponding to an antibacterial device and an ozone generating device) 18 is provided in the switching chamber 5 and in the cold air inflow path. An ozone treatment device 19 is provided in the cold air outlet.

In addition, the switching chamber 5 can be set to a set temperature suitable for the user according to modes such as freezing, micro-freezing, quick-freezing, vegetable, high-temperature vegetable, soft freezing, refrigeration, and wine by selecting a set temperature zone.

In the refrigerator configured as described above, the operation thereof will be described below.

When accommodating low-temperature sensitive fruits such as bananas, eggplants, cucumbers, etc. that are discolored, softened, and water-swelled when they are too cold, the mode of the switching chamber 5 is selected as "high temperature vegetables", and the mode is changed in the switching chamber 5.

The switching chamber 5 changed to the "high temperature vegetable" mode is cooled to a temperature of 10-15°C, and at the same time, the deodorizing and antibacterial device 18 installed in the cold air inlet path is driven to generate ozone, and antibacterial treatment is performed on the cold air flowing into the switching chamber 5 At the same time, the ozone treatment device 19 installed in the cold air outlet is driven to decompose the ozone and make the harmful ozone harmless to the human body.

In addition, at this time, since the generated ozone is supplied into the switching chamber 5 in a state contained in cold air, the switching chamber 5 is filled with ozone, so that the air in the switching chamber 5 and the growth of miscellaneous bacteria such as mold on the surface of vegetables can be prevented.

Therefore, it is possible to maintain the freshness of low-temperature-sensitive fruits stored at a relatively high refrigeration temperature. On the other hand, the ozone generation amount of the deodorization and antibacterial device 18 is set so that the ozone concentration in the switching chamber 5 is 0.005 ppm or less. , will not affect the user who has opened the door 9 of the switching chamber 5, and does not feel ozone.

In addition, at present, ozone having a strong oxidizing effect is used for sterilization, mold prevention, and the like in refrigerators and the like. For example, the storage room of the batch refrigeration type refrigerator described in Patent Document 2 is provided with an evaporator (cooler) and an air supply unit in another room, and the air cooled by the evaporator is blown to the storage room by the air supply unit. Cool the pantry. Therefore, the air in the storage room flows forcibly, and ozone is generated in the airflow, so that bacteria are sterilized and antibacterial throughout the entire storage room.

Patent Document 1: (Japanese) Patent No. 3920064

Patent Document 2: (Japanese) Unexamined Patent Publication No. 2001-91146

However, in the above-mentioned conventional refrigerator, there is a problem that ozone may not be supplied efficiently.

That is, in the above-mentioned conventional structure, for the low-concentration ozone generated by the deodorizing and antibacterial device 18 installed in the inflow path, it is difficult to diffuse into the entire storage room because it moves only depending on the cold air flow.

When ozone diffuses into the storage room and the ozone concentration is not uniform, the functionality of stored items in the storage room cannot be improved.

In addition, when ozone is generated in the state where the air in the storage room is flowing, the ozone will flow out to other rooms, so the ozone concentration becomes thinner. Outflow, so the ozone concentration becomes thicker.

It is considered that even if the ozone concentration in the storage room changes due to the cooling state of the storage room, a certain effect of sterilization and antibacterial can be obtained, but the effect of the extraordinary change in the concentration of the ozone will greatly hinder the decomposition of chemical substances such as pesticides, and it is found that the concentration of ozone stabilization is extremely important.

Contents of the invention

This invention was developed in consideration of the said conventional subject, and it aims at providing the food storage which can efficiently supply ozone to a storage room inside.

In order to achieve the above objects, a food storage according to an aspect of the present invention includes: a storage box forming a storage room for storing food; a door for opening and closing the storage box; and an ozone generator for generating ozone supplied to the storage room. The storage room is divided into a plurality of storage areas, and the ozone generated by the ozone generator is discharged to a largest storage area among the plurality of storage areas.

According to this, by diffusing ozone into the storage compartment, the ozone concentration can be made uniform, and the functionality of stored objects in the storage compartment can be efficiently improved. Thereby, ozone can be efficiently supplied to the inside of a storage compartment.

In addition, in order to achieve the above object, a food storage according to an aspect of the present invention includes: a storage box forming a storage room for storing food; a door for opening and closing the storage box; A refrigerating cycle of the refrigerant flow path; an ozone generating device that generates ozone supplied to the storage room; an internal environment setting unit that changes the environment in the storage room; A control unit that operates to control the operation of the ozone generator.

(Embodiment 1)

The food storage of the first aspect of the present invention includes: a storage box forming a storage room for storing food; a door for opening and closing the storage box; and an ozone generating device for generating ozone supplied to the storage room, the storage room being divided into a plurality of storage area, and discharge the ozone generated by the ozone generator to the largest storage area among the plurality of storage areas.

As a result, the functional substance can be efficiently diffused to the storage area inside the storage room, that is, the largest storage area, where there are many preserved objects, and the ozone can be spread more evenly in the storage room, thereby efficiently improving the storage capacity of the storage room. The functionality of the product, so it can provide a higher quality cold storage.

In addition, in the food storage, it is preferable that the storage room is divided into the plurality of storage areas by installing a plurality of storage containers, and that the ozone generator is installed at a position facing the largest storage container among the plurality of storage containers.

Therefore, in the storage room divided into storage containers, an ozone generating device can be provided at a position facing the largest storage container, and when ozone is discharged to a large storage container, it can be realized with a simpler structure, and the ozone can be made more uniform. It is possible to efficiently improve the functionality of the stored items inside the storage room, thereby providing a higher-quality refrigerator.

In addition, in the food storage, it is preferable that the storage room is divided into the plurality of storage areas by installing a plurality of storage containers, and the ozone generator is installed directly above the largest storage container among the plurality of storage containers.

Thus, utilizing the fact that ozone has a tendency to diffuse toward the gravitational direction, i.e., the downward side, due to its specific gravity being heavier than air, when discharging ozone into a large storage container, utilizing the diffusivity from the top to the bottom, it is possible to dissipate the ozone with a simpler structure. The introduction of ozone into the large storage container can make the ozone spread more evenly in the storage room, and can effectively improve the functionality of the stored items in the storage room, thus providing a higher-quality refrigerator.

In addition, it is preferable that the food storage further includes an adjustment member for adjusting a discharge range in which ozone generated by the ozone generator is discharged into the storage room on the side of the storage room of the ozone generator.

Thereby, depending on the structure inside the storage room, the ozone can be diffused to every corner inside the storage room, and depending on the structure of the storage room, the ozone can be spread uniformly in the storage room with a simple structure.

In addition, in the food storage, it is preferable that the adjustment member has a passage hole through which ozone passes, and the total area of the passage holes communicating with the largest storage region among the plurality of storage regions is set to be larger than the total area of the passage holes communicating with other storage regions. large area.

Thus, the amount of ozone supplied to a plurality of storage areas can be adjusted with a simple structure, and a larger amount of ozone can be supplied to the largest storage area. Therefore, according to the structure of the storage room, the ozone can be spread evenly in the storage room with a simple structure. storage room.

Next, embodiment of the food storage of this invention is demonstrated with reference to drawings.

Fig. 1 is a front view showing a food storage.

As shown in the figure, the food storage 100 is a refrigerator provided with three doors 111a, 111b, 111c, and the storage room formed by the storage box 170 is divided into three.

The food storage 100 is provided with the refrigerator compartment 110, the vegetable compartment 120, and the freezer compartment 130 as the storage compartment divided from the upper part. In the same figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried into and out of the shelf-shaped storage box 170 from the front.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 includes a first door 111a that can open and close the refrigerator compartment 110, a second door 111b that can open and close the vegetable compartment 120, and a third door 111c that can open and close the freezer compartment 130. The doors 111a, 111b, and 111c pass through The hinge is installed on the storage box 170 in a switchable manner.

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

Fig. 2 is a longitudinal sectional view of food storage 100 according to the embodiment.

As shown in the figure, the food storage 100 is equipped with the ozone generator 200, the isolation unit 210, and the light source 220 which is an activation unit. In addition, the food storage 100 installs the food container 121 and the cover 122 in the inside of the vegetable compartment 120 . Moreover, the rear part in the food container 121 is further provided with the upper container 123 as a food container.

The food container 121 has a large capacity and depth, so it will not damage leafy vegetables such as spinach and root vegetables such as radishes, and is suitable for preservation. In addition, the upper container 123 has a small capacity and is usually called a fruit box, which is suitable for storing apples and other fruits. Fruits such as grapes.

The ozone generator 200 is a device capable of generating ozone to be supplied to the food container 121 arranged in the storage room. Ozone generator 200 is buried on the lower surface side of heat insulating wall 115 that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is arranged above the opening 127 of the food container 121 with a large capacity, and is arranged at a position away from the opening 127 of the food container 121 and facing the opening 127 .

Thus, by embedding the ozone generator in the heat insulating wall 115, the temperature of the ozone generator 200 is hardly changed by the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

Isolation unit 210 is a member made of a thin plate that separates ozone generator 200 from the storage room, and functions as an adjustment member that adjusts the discharge range of ozone generated by ozone generator 200 into vegetable compartment 120 .

As shown in FIG. 3 , an inverted truncated pyramid-shaped cover is provided with a plurality of discharge holes 211 , which are passage holes communicating with a vegetable compartment 120 , which is a storage compartment, in front of the lower surface. The isolation unit 210 is attached to the lower surface of the heat insulating wall 115 so as to cover the ozone generating device 200 embedded in the heat insulating wall 115, and isolates the ozone generating device 200 and the vegetable compartment 120 from each other. The discharge hole 211 is a passage hole connected to the largest storage area, and the total area of the discharge hole 211 is larger than the total area of the passage holes connected to the other storage area, that is, the upper container 123 .

In addition, the isolation unit 210 is provided with a suction hole 212 behind the lower surface. The suction hole 212 arranged at the rear mainly functions as a hole for sucking in the atmosphere outside the isolation unit 210 . In the case of this embodiment, since this suction hole 212 is located in the vicinity of the cold air discharge port 213 mentioned later, it sucks the cold air of a relatively dry state. Therefore, the humidity inside the isolation unit 210 can be kept low, and the ozone generation efficiency of the ozone generator 200 which has a higher generation efficiency as the humidity is lower can be maintained in a high state.

In addition, by making the discharge hole 211, which is the through hole communicating with the largest storage area, located at the front side, the ozone generating device 200 can be disposed at a position away from the cold air outlet 213, that is, on the downstream side, and the ozone generated by the ozone generating device 200 is easily discharged to The upper container 123 , which is a small storage area on the rear side, is located in the food container 121 , which is a large storage area in front of the upper container 123 .

In this way, the isolation unit 210, which is an adjustment member for adjusting the effect of the function additional device, is installed on the lower part of the heat insulating wall 115 by covering the ozone generating device 200 buried in the heat insulating wall 115, that is, it is more dense than the ozone generating device 200. The inner side of the vegetable compartment 120 separates the ozone generator 200 from the storage space of the vegetable compartment 120 .

In addition, by providing a plurality of discharge holes 211 in the isolation unit 210, the ozone discharge amount and discharge range of the ozone generator 200 into the vegetable compartment 120 are adjusted.

Specifically, the lower surface of the spacer unit 210 , which is an adjustment member, forms a storage portion 210 a near the center without the discharge hole 211 , and the discharge hole 211 is arranged on the left and right sides of the storage portion 210 a. Therefore, the ozone generated by the ozone generator 200 temporarily accumulates near the storage portion 210a near the center of the isolation unit 210 without the discharge hole 211, and the ozone with a specific gravity heavier than air gradually diffuses to the entire lower surface of the isolation unit 210. It is discharged downward from the left and right discharge holes 211 arranged in the storage part 210a. In addition, since there are a plurality of discharge holes 211, they can spread over the entire food storage 100.

In addition, in this embodiment, by providing the isolation unit 210 between the food container 121 and the ozone generator 200, which has high humidity due to the emission from vegetables, the upper part of the isolation unit 210, that is, the periphery of the ozone generator 200 can be maintained. for lower humidity.

In addition, when the type of the ozone generator 200 is a type that generates ozone at a high voltage, in the temperature distribution in the storage room, since cool air flows in from the outside of the storage room, by installing near the cold air discharge port 213 at a low temperature, In the case of the ozone generator 200, the inside of the isolation unit 210 becomes low temperature, whereby ozone can be efficiently generated. Therefore, power consumption necessary for ozone generation can be suppressed, and energy saving can be contributed.

In addition, the isolation unit 210 can adjust the ozone concentration of the vegetable compartment 120 according to the relationship between the ozone generation efficiency of the ozone generator 200, the amount of oxygen flowing into the isolation unit 210 through the suction hole 212, and the amount of ozone flowing out of the discharge hole 211.

That is, the isolation unit 210 which is an adjustment unit can adjust the ozone concentration of the vegetable compartment 120 to some extent by determining the total opening area of the discharge holes 211 provided in the isolation unit 210 at the design stage. Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in vegetable compartment 120 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration of the vegetable compartment 120 up to the limit of the capacity of the ozone generator 200 . On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in vegetable compartment 120 decreases.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the food container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone generation of the ozone generator 200 based on the information from the ozone concentration meter. amount to keep the ozone concentration in the food container 121 within a prescribed range.

It is preferable to maintain the ozone concentration in the vegetable compartment 120 and the food container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, when pulling out the food container 121 and taking out foods such as vegetables from containers such as the food container 121, some effects may be exerted on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

Fig. 4A shows a food container 121, an upper container 123 serving as a food container, and a lid 122, and Fig. 4B is a perspective view of the lid of Fig. 4A.

The food container 121 is disposed in the vegetable compartment 120 which is a storage room, and is a drawable box with an opening at the top.

The lid 122 is a plate-shaped member that seals the opening of the food container 121, has a passage hole 124 and an adjustment hole 125, and functions as a second adjustment member. That is, after the ozone diffused from the ozone generator 200 is temporarily accumulated in the upper part of the cover 122, it is uniformly diffused into the food container from the passage hole 124 and the adjustment hole 125.

In the present embodiment, a configuration is adopted in which, in addition to the isolation unit 210 which is the adjustment unit described above, a cover 122 functioning as a second adjustment unit is provided, and by providing the isolation unit 210 as the first adjustment unit, , and a cover 122 as a second adjustment unit is provided on the side closer to the storage compartment than the first adjustment unit, that is, the isolation unit, and a plurality of adjustment units are overlapped.

In addition, the lid 122 has the function of adjusting the humidity in the food container 121. Specifically, it maintains the moisture emitted from the vegetables stored in the food container 121 in the food container 121 to some extent, and at the same time adjusts the humidity to the above-mentioned level. The degree to which moisture does not condense in the food container 121 .

Moreover, the slope part 122a located in the upper part of the upper container 123 which is a small storage area is attached to the rear side of the cover 122. As shown in FIG.

It is comprised so that ozone may pass through the passage hole 124 provided in the inclined part 122a less easily than the flat part 122b located in the lower part of the ozone generator 200. As shown in FIG. That is, it is configured such that the ozone falling from the upper side of the flat portion 122b as shown by the arrow A passes through the passage hole 124 installed in the flat portion as shown by the gravity and falls as shown by the arrow B, but from the side of the flat portion 122b The ozone diffused by the inclined portion 122a is diffused as shown by the arrow C. When the ozone does not flow in the direction shown by the small arrow D due to flowing in from the through hole 124 installed on the inclined portion 122a, it is physically difficult to pass through the hole installed on the inclined portion 122a. The inclined portion 122a passes through the hole 124 . That is, in the inclined portion 122a, the diffusion direction of ozone is different from the inflow direction of the passage hole 124, and the composition that does not flow in when the angle of 90 degrees or more is not changed with respect to the diffusion direction of ozone is used to reduce the amount of ozone passing through the passage hole. way to adjust. On the other hand, since the inflow direction of the passage hole 124 provided in the inclined part is along the inflow direction of the cool air from the cool air discharge port 213, the cool air from the cool air discharge port 213 is easily passed.

In this way, in this embodiment, even if the total area of the passage hole 124 installed in the adjustment member, that is, the cover 122 is the same, by this structure, it will become the food container with the largest storage area among the storage containers. 121 emits more ozone.

In this way, in the present embodiment, the lid 122 which is the adjustment member can adjust the range of discharge to the storage compartment.

The food container 121 is arranged in the vegetable compartment 120 which is a storage room, and is a drawable box having an opening 127 opened upward.

The lid 122 is a plate-shaped member that seals the opening 127 of the food container 121 , and includes a passage hole 124 and an adjustment hole 125 . In addition, the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the light radiated from the light source 220 . The lid 122 has the function of adjusting the humidity in the food container 121. Specifically, the moisture emitted from the vegetables stored in the food container 121 is maintained in the food container 121 to a certain extent, and the humidity is adjusted to the above-mentioned humidity at the same time. The degree to which dew does not condense in the food container 121 .

The passage hole 124 is a hole mainly having a function of passing ozone, and is a hole penetrating through the cover 122 in the thickness direction. In addition, as shown in FIG. 5 , the passage hole 124 has a conical shape whose diameter gradually expands upward. In addition, the passage hole 124 is a hole for introducing the ozone generated by the ozone generator 200 into the inside of the food container 121 .

By forming the passing hole 124 in such a shape, the large diameter part of the passing hole 124 can catch the ozone falling from the discharge hole 211 of the partition unit 210, and the ozone can be efficiently introduced into the food container 121. On the other hand, the moisture present in the food container 121 can be consistent with the outflow of the adjustment hole 125 described later, and the humidity inside the food container 121 can be adjusted according to the design concept.

In this way, in this embodiment, by providing the isolation unit 210 as an adjustment member arranged to cover the ozone generator 200, the ozone gas generated by the function adding device, for example, is not directly discharged into the storage room, but is temporarily stored. Discharge after the inside of the isolation unit 210 which is the adjustment member, and discharge the ozone into the storage room through the through hole 124 installed in the cover 122 which is the adjustment member, so that the ozone discharge amount and discharge range can be easily adjusted.

In addition, in this case, the ozone generator 200 is disposed above the food container 121, which is the largest storage area among the storage areas in the vegetable compartment 120, that is, the ozone generator 200 is installed at a position facing the food container 121. .

Thus, in the storage room divided by the storage container, an ozone generating device can be installed at a position opposite to the largest food container 121, and when ozone is discharged to the large food container 121, it can be realized with a simpler structure and can be used. Ozone spreads more uniformly in the storage room, and can efficiently improve the functionality of stored items in the storage room, thereby providing a higher-quality refrigerator.

Moreover, it is comprised so that ozone may be supplied to the upper container 123 which becomes a smaller storage area among storage containers via the food container 121. FIG.

Moreover, the food storage 100 is equipped with the cooling unit 140. As shown in FIG. In the case of the present embodiment, cooling unit 140 is constituted by a cooling cycle including two coolers. Specifically, first cooler 112 is installed on the rear side of the inner surface of refrigerator compartment 110 . The inner surface of refrigerator compartment 110 is cooled by heat conduction from cooler 112 . The air in refrigerator compartment 110 is cooled by the cooled inner surface.

In addition, the second cooler 112 is installed on the rear side of the inner surface of the freezing compartment 130 . The inside of freezer compartment 130 is cooled by the cooled air that forcibly passes through second cooler 112 , and the cold air that has cooled food etc. returns to second cooler 112 again.

The cool air discharged from second cooler 112 is also supplied to vegetable compartment 120 through cool air outlet 213 . Vegetable compartment 120 controls the amount of cool air supplied by controlling the opening and closing of the damper, and maintains a temperature range between the temperature range of refrigerator compartment 110 and the temperature range of freezer compartment 130 . Specifically, it is controlled so as to maintain the temperature in the range of 4°C or lower and 0°C or higher.

In addition, the light source 220 is an activation promotion unit that promotes the decomposition of harmful substances such as agricultural chemicals in this embodiment, and is a light emitting diode that emits light of a predetermined wavelength that activates the biological defense reaction of the green fruit stored in the vegetable compartment 120, which is the storage compartment. (LED). Activated green fruit is a fruit in which antioxidant substances, namely vitamins, are increased, ozone is used to decompose harmful substances such as pesticides, and vitamins increased in green fruits are used to decompose harmful substances such as pesticides attached to the surface of green fruits. Thereby, the decomposition of pesticides by ozone can be accelerated.

This light source 220 is also installed in the upper part of the upper container 123 suitable for storing fruit called a fruit box even in a storage container.

In addition, the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

In addition, in order to efficiently activate the living body defense reaction of the green fruit, the LED element of the light source 220 preferably uses blue light with a central wavelength of 470 nm as the wavelength for penetrating the light into the surface of the green fruit. wavelength, preferably green light with a center wavelength of 520nm. The irradiation intensity from the light-emitting light source 13 including the blue LED and the green LED to irradiate the object to be irradiated (green fruit) at this time is appropriately within the range of 5 to 500 Lx.

With regard to the irradiation intensity, when the irradiation intensity is less than 5 Lx, it is difficult to increase vitamins which are antioxidant substances to be increased as a biological defense reaction under light irradiation. In addition, when the irradiation intensity is weak to less than 5Lx, it becomes difficult for the consumer, that is, the user to recognize the lighting when opening and closing the door, so it is actually difficult to obtain the effect of the product when it is installed in the refrigerator. Appreciate the effect of this appeal.

On the other hand, if it exceeds 500Lx, the amount of light is too strong, which may actually promote the release of green fruits, which may reduce the freshness. In addition, the light after irradiation may cause functional quality deterioration such as refraction or discoloration depending on the situation. In addition, when the light intensity is too strong when opening and closing the door, it also tends to be difficult for the consumer, that is, the user, to have a refreshing feeling as a refrigerator.

According to these theories, as the amount of light of the light source 220, the illuminance range of 20 to 100 Lx is more preferably an effective range in terms of functions to increase the antioxidant substance vitamins without promoting the emission of green fruits, and it is more preferable to set it in the sensory sense. When opening and closing the door, users can feel the functional effect achieved by the light from the light source and have a cool and refreshing illuminance range.

In addition, the irradiation intensity of green light is preferably stronger than that of blue light. In this embodiment, the ratio of the illuminance of the green LED to the illuminance of the blue LED is about 3 to 10 times.

In addition, in an actual product, when confirming the intensity of the irradiation ratio, the intensity of the illuminance of the storage space and the space can be confirmed by using an illuminance meter. Specifically, when two colors are irradiated at the same time, the switching of the control board etc. is changed to irradiate one color and one color, and when the respective illuminances are measured, the intensity of the illuminance of each wavelength, that is, each color can be confirmed.

This is because green light is light of a wavelength that has little side effects on green fruits. Therefore, it is effective to enhance the illuminance of green light penetrating into the green fruit to increase the amount of antioxidant substances in green fruits, that is, vitamins. It will deteriorate the quality of green fruits and increase the amount of vitamins. It has been found from experiments that it is effective to set the illuminance of light in a range in which green light is about 3 to 10 times that of blue light. That is, when it is less than 3 times, the effect of increasing the amount of vitamins inside the green fruit is insufficient, and when it exceeds 10 times, it is difficult to expect the effect of increasing the amount of vitamins on the surface of the green fruit. In either case, it is difficult to obtain The effect of a comprehensive increase in the amount of vitamins.

In addition, for green fruits, compared with continuous light irradiation, intermittent irradiation stimulates vegetables more. In addition to vitamin C production through photosynthesis, it can also promote the production of vitamin C, an antioxidant substance in the defense reaction of vegetables. The removal of harmful substances such as pesticides can also be promoted, so the light source 220 is preferably controlled so that the green LED and the blue LED simultaneously perform flash irradiation (intermittent irradiation) at any frequency in the range of 20 to 50 Hz around 40 Hz.

In the case where the user can clearly confirm visually by setting the intermittent illumination, that is, the flash at a slow flickering of 20 Hz or less, there is a problem that when the light flickers, it feels as if some kind of abnormality is being reported. Anger such as warning, or psychological depression caused by staring at flickering, or anxiety induced by visual stimulation.

In addition, flicker irradiation is carried out at such a frequency of 20 Hz to 50 Hz, that is, at a frequency of 50 Hz or less which is a power supply frequency in various foreign countries such as Japan, China, and European countries. Then, after using the lighting device and LEDs used at the power supply frequency which are generally popular by using the frequency lower than the power supply frequency, the reliability of the light source 220 can be improved by flickering at a frequency lower than these frequencies.

In addition, the wavelengths emitted by the light source 220 are blue and green, but may be infrared wavelengths that induce vibrations of molecules constituting harmful substances such as agricultural chemicals.

The wavelength including the infrared region is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide, and is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, wavelengths corresponding to valleys of the spectrum, such as the wavelength of the portion with the strongest absorption capability, are preferable. For example, in the molecular structure of harmful substances such as pesticides, "-CH3" often exists as a functional group, and the infrared absorption spectrum of the -CH3 functional group is 3378nm (wavenumber 2960/cm) and 3484nm (wavenumber 2870/cm). Therefore, when the wavelength radiated from the light source 220 is set to a wavelength in the infrared region including 3378nm (wavenumber 2960/cm) and 3484nm (wavenumber 2870/cm), the light radiated from the light source 220 is likely to be absorbed by harmful substances such as agricultural chemicals. -CH3" part produces decomposition.

In addition, for example, wavelengths specified by the infrared absorption spectrum of organophosphorus pesticides such as chlorpyrifos, malathion, or quinthion, and pyrethroid pesticides such as permethrin are preferable. The reason is that these pesticides are commonly used in foods and have a high possibility of remaining in foods. In addition, organophosphorus pesticides are highly toxic pesticides compared with other pesticides, and therefore, by removing them if possible, the safety to the human body can be further improved. In addition, since the wavelengths of these infrared rays exist in the range of 800 to 3000/cm, the wavelengths emitted by the light source 220 are preferably in this wavelength range.

In addition, the wavelength of the infrared rays passing through the light source includes the wavelength activated by ozone, and a light source may be used as the ozone activating means. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if ozone is activated, it promotes the decomposition of harmful substances such as pesticides.

Therefore, when the wavelength including the infrared region is an activation unit for activating harmful substances such as pesticides, it can also be used as an ozone activation unit for activating ozone at the same time. wavelength.

In addition, the light emitting method of the light source 220 is preferably a method that easily decomposes harmful substances such as pesticides. For example, it is considered that the light source is driven only when the ozone concentration in the vegetable compartment 120 is above a predetermined value, that is, when ozone is used to decompose harmful substances such as pesticides. 220 way. In consideration of the decomposition efficiency of harmful substances such as pesticides, the above-mentioned predetermined value is preferably 0.01 ppm or more. It is also effective to blink the light source 220 at light emission intervals corresponding to multiples or submultiples of the natural frequency of the molecules constituting the pesticide. Therefore, it is considered that light energy can be injected into pesticides more efficiently, and it is convenient to break and decompose molecular bonds of harmful substances such as pesticides with ozone.

In addition, in this embodiment, although light emitting diodes are used as the light source 220, it is not limited to this in particular, The light source 220 which radiates light may be sufficient. In addition, when a plurality of light emitting diodes that emit light of different wavelengths are combined as the light source 220, more layers of effects can be obtained.

In addition, in the present embodiment, the light source 220 is used as the activation means, but the ozone gas generated by the ozone generator 200 may be used as a means for activating the biological defense reaction of vegetables. When the defense reaction of the living body of green fruit is activated, there is vitamin C as an antioxidant substance discharged, but when 0.03ppm ozone gas is stored in spinach for 24 hours, the vitamin C of spinach before storage is 73.5mg/100g , increased to 83.8mg/100g after preservation. In this way, when ozone gas is used as an activation unit for activating the defense reaction of green fruits, the light source 220 does not need to be provided, and the ozone generating device 200 can be used as an activation promotion unit instead, so there is no need for manufacturing cost and installation. space, so it is more efficient, the space available for food storage is increased, etc.

In addition, as the wavelength of light irradiated from the light source 220 , the following effects are expected, and it is also useful to use blue and green light.

First of all, when blue light having a peak wavelength around 400nm to 500nm is used, it is possible to prevent deterioration of synthetic resins, etc., which are commonly used in refrigerators, compared to ultraviolet wavelengths, etc., thus suppressing lipid oxidation, etc. After the quality deteriorates, as a unique effect of blue wavelength, it also has the effect of inhibiting the reproduction of bacteria and mold, so it can keep the inside of the refrigerator and the surface of the preserved goods or green fruits clean. In addition, when installed in an actual refrigerator, the refreshing feeling of blue also has a sensory effect of giving the user a clean impression.

In addition, when green light having a peak wavelength around 500nm to 600nm is used, it is possible to prevent deterioration of synthetic resins, etc., which are commonly used in refrigerators, compared to ultraviolet wavelengths, and as an effect unique to green wavelengths, light penetrates into green fruits Therefore, it can act on the inside of the green fruit, promote the defense response of the living body from the inside side, and further increase nutrients such as vitamins.

Therefore, when a combination of blue wavelength and green wavelength light is emitted from the light source 220, the blue wavelength light can be used to inhibit the growth of bacteria on the surface of the green fruit, and the green wavelength that penetrates into the green fruit can be used to promote greenness. The internal living body defense reaction of the fruit can further improve the preservation of the green fruit.

In addition, regarding the irradiation method of the light source, the above-mentioned effect can be obtained even by continuous irradiation, but the stimulation will be stronger by flickering the light source, so in the blue light, the effect of inhibiting the growth of bacteria can be increased. , able to promote the living defense response on the surface of green fruits. Also, in green light, the living defense from the inside can be further promoted, so it is an effective method of irradiation.

As mentioned above, since the food storage 100 of the present invention activates the harmful substances such as pesticides remaining in the stored green fruits or foods by irradiating light, which is the activation unit, and makes them easily decomposable, it is easy to decompose even if it is used on the human body. Low-concentration ozone gas without any influence can efficiently decompose and remove harmful substances such as pesticides.

In addition, pesticides can be decomposed even in an environment below 4°C where the activity of pesticides is low, so food can be preserved for a long time, and residual pesticides can also be decomposed.

In addition, ozone gas also has an effect of reducing ethylene gas, so it is possible to prevent deterioration of vegetables such as vegetables and other foods such as browning due to ethylene gas.

In addition, compared with vegetables, fruits tend to have a large amount of pesticide residues. Therefore, in this embodiment, the light source 220, which is an activation unit that can further increase the removal rate of pesticides by activating pesticides, is also installed in the storage container. Just above the upper container 123 that is suitable for accommodating fruit called a fruit box. In this way, the light source 220 can improve the pesticide removal rate of the fruits stored in the upper container 123 by being installed on the upper part of the upper container 123 suitable for storing fruits, so that the pesticide removal of fruits with a large amount of pesticide residues can be further promoted. For example, when comparing residual pesticide values based on the residual pesticide standards (standard value list) of fruits and vegetables, the residual pesticide standard of chlorpyrifos, which is an organophosphorus pesticide, is 1 ppm for green stems and 1 ppm for apples, which are the same values. But when the residual pesticide standard value 1ppm is converted into pesticide weight, a leaf of green stems is about 20g, and an apple is about 300g, so the residual pesticide amount of chlorpyrifos in 20g green stems is 20mg, and the residual pesticide amount of chlorpyrifos in 300g apples 300mg. That is, it was confirmed that, for example, even with the same residual pesticide reference value, apples with a higher specific gravity had more residual pesticides adhered to than green stalks with a lighter specific gravity. In addition, fruits such as apples and oranges are mostly waxed during distribution.

Therefore, in this embodiment, the food container 121, which is the division that mainly accommodates vegetables, and the upper container 123, that is, the division that mainly accommodates fruits, are separated, and the upper container 123 that is the division that mainly accommodates fruits is made to improve the removal of harmful substances such as pesticides. The removal rate of the vegetable room as a whole can promote the removal of harmful substances such as pesticides, which is related to the provision of safe food to consumers.

In this way, when the light source 220, which is the activation unit that activates the pesticide itself, is disposed directly above the upper container that mainly houses the fruit, the upper container 123 is set as a container made of a light-transmitting material, and is configured so that light passes through the upper container. It is also irradiated to the food container 121, thus, in addition to the upper container 123 where the pesticide is more easily decomposed, the light is also irradiated to the food container 121, thus when compared with the upper container 123, although the amount of irradiation is small, after all it is carried out. Light irradiation, therefore, can further promote the removal of harmful substances.

In addition, in this way, by disposing to irradiate a stronger amount of light from the light source 220 to the divisions of the stored fruits, for example, in green and yellow vegetables such as green vegetables such as green stems, when strong light is irradiated, the emission from the vegetables is promoted. , may reduce the moisture in the vegetables, even in this case, the light that irradiates the division that mainly accommodates vegetables is the light that is irradiated through the upper container 123, so the light amount can be set to be weaker, so there is no need to worry about such vegetables To reduce the moisture inside, a light source 220 may be provided. In addition, the surface of the fruit is usually covered by the skin, so compared with green and yellow vegetables such as green stems, there is less emission caused by light irradiation, and there is no need to worry about the reduction of moisture caused by light. From the viewpoint of freshness, it becomes a reasonable composition.

In addition, the ozone generator 200 is preferably installed in front of the food container 121 . This is because the upper container 123 is installed at the rear of the food container 121, so when the ozone generating device 200 is arranged at the rear, the ozone gas will temporarily accumulate in the smaller storage division, that is, the upper container 123, and then the accumulated The gas diffuses to the food container 121 and can fill the food container 121 more efficiently. Therefore, by being arranged in front of the upper part avoiding the upper container 123, the ozone is discharged centered on the food container 121, which is a large storage division, and thus further Improve the diffusibility of ozone.

In addition, in this embodiment, food container 121 is provided in vegetable compartment 120 , but the present invention is not limited thereto, and food may be directly stored in vegetable compartment 120 without food container 121 and its cover.

In addition, although the storage box 170 is partitioned by the fixed heat insulating wall 115, when it is not necessary to partition by a heat insulating wall in particular, you may partition by the partition wall which is not limited to a heat insulating material.

In addition, the activating means may include light in the visible region. In this case, the food stored in the appliance container 121 is irradiated by the light-emitting diode, and the food can be seen without opening the food container 121, so usability is improved. In addition, when the number of times of opening the food container 121 is reduced, the ozone gas generated in the food container is less discharged to the outside, so it also has the effect of removing harmful substances such as agricultural chemicals.

(Embodiment 2)

The food storage according to one aspect of the present invention includes a storage box forming a storage room for storing food, a door for opening and closing the storage room, a compressor, a condenser, a pressure reducer, and an evaporator to form a series of refrigerant flow paths. A refrigeration cycle, an ozone generating device that generates ozone supplied to the storage room, an interior environment setting unit that changes the environment in the storage room, and an operation of the ozone generation device that is controlled by the operation of the storage environment setting unit Control's food storage.

Thus, the ozone generating device can variably control the operation rate of the ozone generating device according to the environmental change in the storage room of the refrigerator, even if the environment in the storage room changes, the concentration of ozone can be maintained stably, and the Provide higher quality food storage.

In addition, in the food storage, it is preferable that the interior environment setting means of the above-mentioned storage is an ON signal of the compressor, and the above-mentioned control unit detects the ON signal of the compressor, so as to increase the operation rate of the above-mentioned ozone generator. control.

Thus, when the storage room is cooled by the ON signal of the compressor and an air flow is generated in the storage room, by increasing the operating rate of the ozone generator, the spray amount of ozone can be increased, and the air flow in the box can be used to make the ozone Diffusion to a more uniform concentration.

In addition, especially in the case of cooling the storage room by indirect cooling using the heat transfer of blowing the low-temperature cold air cooled by the evaporator (cooler) into the storage room, the ON signal of the compressor generates low-temperature cold air to the storage room. The ventilation of cold air in the storage room is accompanied by indoor circulation, so the ozone concentration in the storage room may drop due to the ozone flowing out of the storage room, but as described in the present invention, when the ON signal of the compressor is detected In this case, by increasing the operation rate of the ozone generator, the spray amount of ozone increases, and it is possible to prevent the decrease of the ozone concentration in the storage room.

In addition, it is preferable that the food storage further has a blower unit for flowing cold air in the storage room, the environment setting unit in the storehouse is an ON signal of the blower unit, and the control unit detects the ON signal of the blower unit. In this case, it controls so that the operation rate of the said ozone generator may increase.

Thus, when an air flow is generated in the storage room with the ON signal of the air blowing unit that makes the cold air flow in the storage room, by increasing the operating rate of the ozone generator, the spray amount of ozone can be increased, and the air flow in the box can be used to Allows ozone to diffuse to a more uniform concentration.

In addition, especially in the case of cooling the storage room by indirect cooling using the heat transfer of blowing the low-temperature cold air cooled by the evaporator into the storage room, the ON signal of the air blowing unit generates low-temperature cold air to circulate into the storage room. The incoming cold air in the storage room is ventilated, so the ozone concentration in the storage room may drop due to the flow of the ejected ozone to the storage room, but as described in the present invention, when the ON signal of the compressor is detected, By increasing the operating rate of the ozone generator, the spray amount of ozone increases, and it is possible to prevent the ozone concentration in the storage room from falling.

In addition, it is preferable that the food storage has a damper in the supply air passage for supplying cool air to the storage room, and the inside environment setting means is an ON signal of the damper, and the control unit detects the ON signal of the damper by Control is performed so as to increase the operating rate of the above-mentioned ozone generator.

Thus, when an air flow is generated in the storage room in accordance with the ON signal of the damper that flows the cold air in the storage room, by increasing the operating rate of the ozone generator, the spray amount of ozone can be increased, and the air flow in the box can be used to Ozone diffuses to a more uniform concentration.

In addition, especially in the case of cooling the storage room by indirect cooling using the heat transfer of blowing low-temperature cold air cooled by the evaporator into the storage room, the ON signal of the damper generates low-temperature cold air and circulates into the storage room. Therefore, the ozone concentration in the storage room may drop due to the ejected ozone flowing out of the storage room. However, as described in the present invention, when the ON signal of the damper is detected, the ozone concentration will be increased by increasing the ozone concentration. The operation rate of the generating device and the spraying amount of ozone are increased, and the decrease of the ozone concentration in the storage room can be prevented.

In addition, it is preferable that the food storage further has an external air temperature detection unit that detects the temperature outside the food storage, the internal environment setting unit is the detection temperature of the external air temperature detection unit, and the control unit detects the temperature detected by the temperature detection unit. When the temperature is higher than a preset value, the operation rate of the ozone generator is controlled to be higher than when the temperature detected by the temperature detection means is lower than the preset value.

Therefore, when the air temperature is high, the temperature in the storage room rises quickly. Therefore, when the airflow is actively generated by actively cooling the storage room, the spray of ozone can be increased by increasing the operating rate of the ozone generator. The amount, using the airflow in the box, can make the ozone diffuse into a more uniform concentration.

In addition, in the present invention, when the air temperature is low, the temperature rise in the storage room tends to be slow, so when it is difficult to cool the storage room and air flow is difficult to generate, the ozone generator can be operated at a low operating rate to prevent ozone The concentration increases, so the ozone concentration in the storage room can be stabilized to a constant value.

In addition, the food storage preferably has a door switch that detects the opening and closing of the door installed in the storage room. The internal environment setting unit detects the opening and closing of the door switch. In the case of , increase the operating rate of the ozone generator.

As a result, cold air in the storage room may flow out of the storage room due to the door being opened, and the ozone concentration in the storage room may decrease. Ozone spray can quickly eliminate the drop in ozone concentration caused by opening the door, and make the ozone concentration in the storage room more stable and constant.

Moreover, it is preferable that a food storage will stop operation|movement of an ozone generator, when the door switch detects that the said door is closed.

Thereby, it is possible to prevent the user from feeling uncomfortable due to the cold air in the storage room flowing to the user's side when the door is opened, and to prevent the user from inhaling a large amount of ozone. Therefore, it is possible to provide higher quality and safer ozone generation Apparatus food storage.

In addition, by opening the door and operating the internal environment setting unit described in the upper claim, the operating rate of the ozone generator can be increased to promote the generation of ozone, but it can prevent the waste of the generated ozone from flowing out of the storage room. , can provide a food storage that is more energy-efficient and keeps the ozone temperature in the storage room constant.

Moreover, it is preferable that an ozone generator operates with a certain constant output in a food storage, and it is preferable to increase the operation time of the said ozone generator, when improving the operation rate of the said ozone generator.

Thereby, the control unit can operate the ozone generator with a constant predetermined output, so a highly safe ozone generator can be provided, and the operating rate of the ozone generator can be increased only by controlling the ON-OFF time of the ozone generator. , Therefore, it becomes simpler and easier control, and therefore it is possible to provide a food storage with a less troublesome and highly safe ozone generator.

Moreover, it is preferable that the food storage is operable with a plurality of outputs of the ozone generator, and when the operation rate of the said ozone generator is improved, the output of the said ozone generator is increased.

Thereby, an ozone generator can be controlled more finely, and the food storage which keeps the ozone density|concentration in a storage room more constant can be provided.

Next, embodiment of the food storage of this invention is demonstrated referring drawings. In addition, this invention is not limited to this embodiment.

In addition, the storage tank 170 includes a compressor 174, a condenser (not shown), a pressure reducer (not shown), and a cooler 112 (hereinafter referred to as an evaporator 112 in this embodiment) to form a series of refrigerant The refrigerating cycle of the flow path is the cooling unit 119 , and the low-temperature cold air realized by the operation of the cooling unit 119 is generated by the evaporator 112 .

In addition, in this embodiment, the cooling in the storage room realized by the evaporator 112 is performed by two cooling methods, direct cooling and indirect cooling. The direct cooling utilizes the heat conduction from the evaporator 112; kind of heat transfer.

Specifically, the refrigerating room 110 is equipped with an evaporator 112 on the rear wall of the refrigerating room 110, and the vegetable room 120 and the freezing room 130 utilize Indirect cooling uses heat transfer in which low-temperature cold air cooled by the evaporator 112 is blown into the storage room.

Moreover, the food storage 100 is equipped with the external air temperature detection means (not shown) which detects the temperature outside the storage of the storage box 170. As shown in FIG.

Moreover, the food storage 100 is provided with the ozone generator 200, the isolation|separation unit 210, and the light source 220. As shown in FIG. In addition, in the vegetable compartment 120 of the food storage 100, an upper container 123 (hereinafter referred to as the first container 123 in this embodiment) and a food container 121 (hereinafter referred to as the first container 123 in the present embodiment) that is a storage container are provided. Two containers 121) form a storage area, and are provided with a cover 122 mounted on the storage container.

The ozone generator 200 is a device capable of generating ozone supplied to the first container 123 and the second container 121 arranged in the storage room. Ozone generator 200 is embedded on the lower surface of heat insulating wall 115 (hereinafter referred to as shelf 115 in this embodiment) that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is disposed above the opening 127 of the second container 121 described later, at a position away from the opening 127 of the second container 121 , and at a position facing the opening 127 .

In addition, the control substrate 132 is electrically connected to the cooling unit 119, the air blowing unit 113, the damper 131, the sensor (not shown), etc., and is a substrate for controlling the above-mentioned devices. The device 200 can generate or stop ozone based on a signal from the control board 132 .

Thus, by embedding the ozone generator in the shelf 115, the temperature of the ozone generator 200 is hardly changed due to the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

In addition, ozone can be generated as needed.

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

The isolation unit 210 is a component made of a thin plate that separates the ozone generator 200 from the storage room. As shown in FIG. . The isolation unit 210 is attached to the lower surface of the shelf 115 so as to cover the ozone generator 200 embedded in the shelf 115 , and isolates the ozone generator 200 from the vegetable compartment 120 . In addition, the isolation unit 210 is provided with a plurality of suction holes 212 in front of the lower face.

The lower surface of the partition unit 210 is inclined so as to descend toward the rear position of the food storage 100, and the discharge hole 211 is arranged near the lowest position.

Accordingly, ozone having a specific gravity heavier than air is mainly discharged downward from the discharge hole 211 . On the other hand, the suction hole 212 disposed in the front mainly functions as a hole for sucking in the atmosphere outside the isolation unit 210 . In the case of the present embodiment, the suction hole 212 sucks the cool air discharged from the cool air discharge port 213 described later and passed along the outer wall of the second container 121 .

The isolation unit 210 can adjust the ozone concentration of the vegetable compartment 120 according to the relationship between the ozone generation efficiency of the ozone generator 200 , the amount of oxygen flowing into the isolation unit 210 through the suction hole 212 , and the amount of ozone flowing out of the discharge hole 211 . That is, the isolation unit 210 can adjust the ozone concentration of the first container 123 and the second container 121 to a certain extent by determining the total opening area of the discharge hole 211 and the total opening area of the suction hole 212 arranged in the isolation unit 210 at the design stage. . Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the first container 123 and the second container 121 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration in the first container 123 and the second container 121 up to the limit of the capacity of the ozone generator 200. On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in the first container 123 and the second container 121 decreases. However, the total opening area of the discharge hole 211 and the total opening area of the suction hole 212 are not the only factors determining the ozone concentration.

Next, the control method of the control unit 133 that controls the operation of the ozone generator 200 through the operation of the storage environment setting unit that controls the operation of the ozone generator 200 for the storage system that emits ozone will be described. The environment of the room gives change to the device.

First, a case will be described in which the interior environment setting means is the compressor 174 or the blower means 113 .

In the present embodiment, the cooling of the vegetable room that emits ozone from the ozone generating device 200 utilizes a cooling method of indirect cooling that utilizes heat transfer such as blowing cold air cooled by the evaporator 112, so the driving of the compressor 174 and The drive of the blower unit 113 is interlocked.

Therefore, as shown in FIG. 11 , the operation rate of the ozone generator 200 is changed by the ON signal driven by the compressor 174 and the ON signal driven by the blower unit 113 .

Specifically, when the compressor 174 is driven by an ON signal, the blower unit 113 also becomes an ON signal, and at this time, the amount of ozone is increased by operating the ozone generator 200 at a high operation rate of 45%.

As described in this embodiment, in the case of cooling the inside of the storage room, that is, the vegetable room 120 by using indirect cooling of heat transfer by blowing low-temperature cold air cooled by the evaporator 112 into the storage room, the compressor 174 is turned ON. The signal generates ventilation of the cold air in the vegetable compartment 120 accompanied by the circulation of the low-temperature cold air into the storage room. That is, the low-temperature cold air flows into the vegetable compartment 120 , and the cold air in the vegetable compartment 120 flows out of the vegetable compartment 120 at the same time.

Therefore, the emitted ozone flows out of the storage room together with the cold air, so the ozone concentration in the storage room may decrease. The spray volume increases, which can prevent the ozone concentration in the storage room from decreasing.

In this way, when the compressor 174 and the blower unit 113 are ON-OFF linked, the internal environment setting means may use either the ON signal of the compressor or the OFF signal of the blower unit.

In addition, in the present embodiment, the vegetable compartment 120, which is a storage room that emits ozone, is set as indirect cooling of heat transfer by blowing the cold air cooled by the evaporator 112, and the internal environment setting unit is a compressor. For the sake of explanation, in the case where the storage room that emits ozone is the cooling method of direct cooling using heat conduction from the evaporator 112, similarly, when the ON signal of the compressor set as the storage environment setting unit is detected In some cases, it is also effective to increase the spray amount of ozone by increasing the operating rate of the ozone generator.

Thus, even in the cooling method of direct cooling, when the storage room is cooled by the ON signal of the compressor and an air flow is generated in the storage room, the spray amount of ozone can be increased by increasing the operating rate of the ozone generator, Ozone can be diffused to a more uniform concentration by utilizing the airflow inside the chamber.

Next, it must be taken into account that the ozone concentration changes depending on the environment such as the air temperature of the food storage 100 .

This is because the temperature in the storage room rises high under the high temperature, so by actively cooling the storage room, the circulation amount of cold air is extremely large, and the ozone does not enter the storage space such as food, that is, the first container 123 and the second container 121. Rather, it is taken out from the vegetable compartment 120 together with the cool air, and the ozone concentration in the vegetable compartment 120 tends to decrease. On the contrary, at a low temperature, the circulation amount of cool air is extremely small, and ozone is not easily carried out from the vegetable compartment 120, and the ozone concentration in the vegetable compartment 120 tends to be high.

That is, the operating state of the refrigerator changes due to the influence of air temperature, whereby the ozone concentration also changes. As will be described later, the stabilization of the ozone concentration is extremely important, and in order to stabilize the concentration, the ozone generation output is variably controlled using a signal from the control board 132 .

Therefore, next, the case where the outside air temperature detection means which detects the temperature outside the storehouse of a food storage is further provided as store interior environment setting means is demonstrated.

Fig. 12 is a graph showing the variable output of the ozone generator in accordance with the air temperature in the refrigerator, the upper graph is an example graph showing the control of the ozone generator at low temperature, and the lower graph is a graph showing the control of the ozone generator at high temperature An example diagram of .

Here, the low temperature is set to be less than 10°C, and the high temperature is set to be 10°C or higher. As shown in the figure, the operating rate of the compressor is very low in the case of low air temperature compared to the case of high air temperature.

As shown in the figure above, in the case of low air temperature, when the compressor is turned on, the ON signal is only for a short time, and the operation rate is increased during the period, and the operation rate is 45%. When the signal is OFF, the operation rate is decreased, and the operation is performed at an operation rate of 10%.

In this way, when the air temperature is low, the temperature rise in the storage room tends to be slow. Therefore, when it is difficult to cool the storage room and air flow is difficult to generate, the ozone generator is operated at a low operating rate to prevent the ozone concentration from increasing. Increase, so the ozone concentration in the storage room can be stabilized to a constant value.

In addition, as shown in the figure below, in the case of high air temperature, the time for the compressor to be ON signal is very long. During the ON signal period of the compressor, it operates at a relatively high operation rate of 30%. When the operation of the signal is OFF, the operation rate is reduced, and the operation is performed at a relatively low operation rate of 15%.

In this way, when the air temperature is high, the temperature rise in the storage room tends to be fast. Therefore, when the air flow is actively generated by actively cooling the storage room, by increasing the operating rate of the ozone generator, the spray of ozone The amount can be increased, and the ozone can be diffused to a more uniform concentration by using the airflow in the box.

In this embodiment, the operating rate of the ozone generator 200 is set so that the operating time of the ozone generating device 200 may be increased when the operating rate of the ozone generating device 200 is increased when operating at a certain constant output.

Thereby, the control unit can make the ozone generator operate with a constant predetermined output, so it can be provided with a highly safe ozone generator, and in addition, only by controlling the ON-OFF time of the ozone generator, the efficiency of the ozone generator can be improved. Since the operating rate becomes simpler and easier to control, it is possible to provide a food storage room equipped with an ozone generating device with few failures and high safety.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, based on a signal from the control board 132, the movement or stop of the fan may be controlled. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the second container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone concentration of the ozone generator 200 based on the information from the ozone concentration meter. The generated amount keeps the ozone concentration in the second container 121 within a predetermined range.

It is preferable to maintain the ozone concentration in the first container 123 and the second container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, when pulling out the second container 121 and taking out food such as vegetables from containers such as the second container 121, some effects may be brought on the human body of the user who performs these operations. . In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

The light source 220 is a device that emits light of a predetermined wavelength that can promote the decomposition of pesticides by ozone for food stored in the vegetable compartment 120 that is a storage compartment. In the case of this embodiment, a light emitting diode (LED) is used as the light source 220 .

In addition, the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

In addition, the wavelength emitted by the light source 220 is a predetermined wavelength that can promote the decomposition of pesticides by ozone on food stored in the storage room, and may be included in any wavelength region of the infrared region, visible region, and ultraviolet region.

Specifically, it is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide, and this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, wavelengths corresponding to valleys of the spectrum, such as the wavelength of the portion with the strongest absorption capability, are preferable. For example, a wavelength specified by the infrared absorption spectrum of chlorpyrifos, or malathion, or quinathion-type pesticides is preferable. The reason is that these pesticides are commonly used in foods and have a high possibility of remaining in foods.

On the other hand, it may be a wavelength activated by ozone. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if activated by ozone, it promotes the decomposition of pesticides.

In addition, the light emitting method of the light source 220 may be a method that easily decomposes pesticides. For example, consider a method in which light source 220 is continuously turned on only when the ozone concentration of vegetable compartment 120 is equal to or higher than a predetermined value. In consideration of the decomposition efficiency of the pesticide, the above-mentioned predetermined value is preferably 0.01 ppm or more. Alternatively, the light source 220 may be blinked at light emission intervals corresponding to multiples or submultiples of the natural frequency of the molecules constituting the pesticide. From this, it is considered that light energy can be more efficiently injected into the pesticide, and the pesticide can be easily decomposed by ozone.

In addition, in this embodiment, although a light emitting diode is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, as the light source 220, a plurality of light emitting diodes that emit lights of different wavelengths may be used in combination.

In addition, in this Embodiment, although the indirect cooling type refrigerator (vegetable compartment 120, freezer compartment 130) was illustrated and demonstrated, this invention is not limited to this.

For example, it may be a direct cooling type refrigerator (refrigerator room 110), and the air blower unit 113 may be provided in the storage room in order to force the air in the storage room to flow. In this case, what is necessary is just to control the ozone generator 200 based on ONOFF of the blower unit 113.

In this embodiment, the operating rate of the ozone generator 200 is set so that the operating time of the ozone generating device 200 may be increased when the operating rate of the ozone generating device 200 is increased when operating at a certain constant output. However, the ozone generator 200 may be operable with a plurality of outputs. In this case, when the operation rate of the ozone generator 200 is increased, control to increase the output of the ozone generator 200 is also performed.

Thereby, the amount of ozone generation can be controlled more finely, and the food storage which keeps the ozone concentration in a storage room more constant can be provided.

(Embodiment 2-2)

Fig. 13 is a graph showing the operating rate of the ozone generator by the damper.

In addition, in this embodiment, description is omitted about the same configuration and technical idea as those of the above-mentioned Embodiment 2-1, and it can be implemented in combination with the configuration described in the above-mentioned Embodiment 2-1.

In this embodiment, the low-temperature cold air cooled by the evaporator 112 is used to blow the low-temperature cold air into the storage room through the supply air path 176. A damper 131 which is a regulating valve for cooling air is provided on the air supply path 176 for supplying the vegetable compartment 120 .

As mentioned above, in this embodiment, the opening and closing of the damper 131 is a large factor that gives the environment in the storage room a change, so the environment setting means in the storehouse is set as the ON signal-OFF signal of the switch of the damper, and the control unit 133 The operation of the ozone generator 200 is controlled by these operations, and the present embodiment describes a control method of the control unit 133 .

In the state where the compressor 174 is operating, the damper is repeatedly opened (ON signal) and closed (OFF signal) as shown in the figure. This is as described in the present embodiment. When cooling the freezer compartment 130 and the vegetable compartment 120 with the same evaporator 112, when the drive of the compressor 174 is used to cool the freezer compartment 130 with a large cooling load as the center. The chamber 120 is supposed to be cooled by supplying cold air by opening the damper 131 only when the temperature inside the chamber rises.

In this case, the ON signal-OFF signal of the compressor 174 does not directly affect the cooling of the vegetable compartment 120 , compared with the compressor 174 , the opening and closing of the damper 131 directly affects the cooling of the vegetable compartment 120 .

Specifically, when the damper 131 is ON when the compressor 174 is ON, the ozone generator 200 is operated at a high operating rate of 45% to increase the amount of ozone. In addition, when the damper 131 is an OFF signal even when the compressor is an ON signal, the operation rate of the ozone generator 200 is reduced, and it is made into about 15%.

As described in this embodiment, in the case of cooling the inside of the storage room, that is, the vegetable room 120 by using indirect cooling of heat transfer by blowing low-temperature cold air cooled by the evaporator 112 into the storage room, the compressor 174 is turned ON. The signal generates the ventilation of the cold air in the vegetable room accompanying the circulation of low-temperature cold air into the storage room. That is, the low-temperature cold air flows into the vegetable compartment 120, and at the same time, the cold air in the vegetable compartment 120 flows outside the vegetable compartment 120, so the emitted ozone and the cold air flow to the outside of the storage room, so the ozone concentration in the storage room may decrease. However, as mentioned above, When the ON signal of the damper 131 is detected, by increasing the operating rate of the ozone generator, the spray amount of ozone increases, and it can prevent that the ozone concentration in a storage room falls.

In addition, in the present embodiment, when the operation of the compressor 174 is ON, the case where the damper 131 is turned on, that is, the ON signal is used as the internal environment setting unit, but the operation of the compressor 174 may not necessarily be ON, for example , using the supply air path 176 that connects the storage room in the temperature zone lower than the storage room that emits ozone and the storage room that emits ozone. The ON-OFF of machine 174 has nothing to do, through the opening (ON) of air door 131, low-temperature cold air flows into the storage room. Therefore, the environment setting unit in the warehouse is only the ON signal of air door 131. , By increasing the operating rate of the ozone generating device, the spray amount of ozone is increased, and the ozone can be diffused to a more uniform concentration by using the airflow in the box.

(Embodiment 2-3)

Fig. 14 is a graph showing the operating rate of the ozone generator realized by door opening and closing.

In addition, this embodiment omits description of the same configuration and technical idea as those of Embodiments 2-1 and 2-2, and can be implemented in combination with the configurations described in Embodiments 2-1 and 2-2.

In this embodiment, the food storage which provided the door switch in the storage room which emits ozone and controls the operation|movement of an ozone generator by ON-OFF of a door switch is demonstrated.

A door switch (shown in the figure) for detecting opening and closing of the second door 111b of the vegetable compartment is installed in the vegetable compartment 120 which is a storage compartment from which ozone is emitted from the ozone generator 200 .

The signal of the door switch is an ON signal when the door is open, and an OFF signal when the door is closed.

When the ON signal of the door opening is detected by the control part, the operation of the ozone generator 200 is stopped, that is, the operation rate is set to 0%. Thereafter, when door closing is detected, control to increase the operating rate is performed for a certain predetermined time. For example, as shown in Fig. 14, the operating rate is set to a maximum of 45% at T1 time after the door is closed, and after T1 time has elapsed since the door is closed, the operating rate is set to be 30% lower than that at T1 during T2 time. , after the T1+T2 time has elapsed since the door is closed, the operating rate is also reduced to 15% of the original value.

Thus, when the door is opened, the ozone generating device 200 is stopped to prevent the cold air flow containing a large amount of ozone from flowing to the user side, suppress the user from feeling unpleasant due to ozone odor, and prevent the user from inhaling a large amount of ozone, so it is possible to provide Food storage for higher quality and safer ozone generating units.

In addition, when the door is opened, it is possible to prevent the generated ozone from being wasted flowing outside the storage, and it is possible to provide a food storage that is more energy-efficient and keeps the ozone concentration inside the storage constant.

In addition, when it is detected that the door is turned from open to closed (from the OFF signal to the ON signal), by operating the ozone generator 200 at a high operation rate, it is possible to more quickly increase the concentration of the outflow due to the door opening. Ozone concentration in the chamber.

In addition, in the present embodiment, when the door is changed from open to closed, the ozone generating device 200 is controlled to have a high operation rate in two stages of time T1 and time T2. It goes without saying that the operation is performed at a high operation rate during (for example, T1+T2), and that the operation rate is lowered after a predetermined time elapses.

In addition, the operating rate of the ozone generator 200 may be changed by using the interior environment setting means as described in the above-mentioned Embodiments 2-1 to 3, which stops when the door is opened and closes.

(Embodiment 3)

The present embodiment relates to a refrigerator provided with a function adding device that functions on stored items stored inside the storage compartment, and an adjustment member for adjusting the action of the function adding device is installed inside the function adding device.

Therefore, it is possible to maintain the freshness of low-temperature-sensitive fruits stored at a relatively high refrigeration temperature.

On the other hand, setting the deodorization and the ozone generation amount of the antibacterial device 18 so that the ozone concentration in the switching chamber 5 is 0.005ppm or less will not affect the user who opened the door 9 of the switching chamber 5 and will not feel it. Ozone smells.

However, in the above-mentioned conventional structure, the deodorization of the switching room and the prevention of storage at a set temperature of 10 to 15° C. The mildew and other miscellaneous bacteria on the surface of the vegetables multiply, and the ozone treatment device 19 is arranged in the cold air flow outlet.

Thereby, the amount of mist inside the storage room can be optimized, and the mist can be diffused to every corner inside the storage room, so that the function can be added more efficiently.

In addition, it is preferable to install a plurality of adjustment members on the inner side of the above-mentioned function adding device closer to the above-mentioned storage room.

In this way, the functional substance generated by the function adding device is once efficiently accumulated by the plurality of adjustment members, and then diffused into the storage compartment, thereby more efficiently acting on the stored items in the storage compartment.

In addition, it is preferable that the interior of the storage room is divided into a plurality of storage divisions, and the adjustment member is located above the division with the largest capacity among the plurality of storage divisions.

Thereby, the functional substance can be diffused efficiently to the site|part in a storage room where many preserved objects exist.

Hereinafter, this embodiment will be described with reference to the drawings.

Fig. 15 is a front view showing the food storage. As shown in the figure, the food storage 100 is a refrigerator provided with three doors 111a, 111b, 111c, and the storage room formed by the storage box 170 is divided into three.

The food storage 100 is provided with the refrigerator compartment 110, the vegetable compartment 120, and the freezer compartment 130 as the storage compartment divided from the upper part. In the same figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried into and out of the shelf-shaped storage box 170 from the front.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 includes a first door 111a that can open and close the refrigerator compartment 110, a second door 111b that can open and close the vegetable compartment 120, and a third door 111c that can open and close the freezer compartment 130. The doors 111a, 111b, and 111c pass through The hinge is installed on the storage box 170 in a switchable manner.

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

Fig. 16 is a longitudinal sectional view of food storage 100 according to the embodiment.

As shown in the figure, the food storage 100 is equipped with an ozone generator 200, and an isolation unit 210 (hereinafter referred to as a cover member 210 in this embodiment) as an adjustment member for adjusting the functions of a light source 220 and a function adding device. add-on. In addition, the food storage 100 installs the food container 121 and the cover 122 in the inside of the vegetable compartment 120 .

The ozone generator 200 which is a function adding device is a device capable of generating ozone to be supplied to the food container 121 arranged in the storage room. Ozone generator 200 is buried on the lower surface side of heat insulating wall 115 that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is arranged above the opening 127 of the food container 121 described later, at a position away from the opening 127 of the food container 121 , and at a position facing the opening 127 .

Thus, by burying the ozone generator 200 in the heat insulation wall 115, the temperature of the ozone generator 200 is hard to change by the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

Here, the ozone generator is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

Fig. 17 is a cross-sectional view of the refrigerator including the vicinity of cover member 210, which is an adjustment member for adjusting the function of the functional attachment.

The regulating part for adjusting the effect of the function additional device is disposed on the inner side of the storage room of the function additional device, that is, the ozone generating device 200, and is a cover member 210 made of a thin plate that separates the ozone generating device 200 from the storage room, as shown in the figure 17 shows a cover member 210 in the shape of an inverted quadrangular truncated pyramid provided with a plurality of discharge holes 211 in front of the lower surface. In this case, cover member 210 , which is an adjustment member, has a plurality of discharge holes 211 to adjust the amount of ozone emitted from ozone generator 200 , which is a function adding device, into vegetable compartment 120 , which is a storage room. That is, the amount of ozone flowing into the vegetable compartment 120 is determined by the size and number of the discharge holes 211 . In addition, depending on the location where the discharge hole 211 is provided, it is possible to adjust the ozone emission range when the ozone is generated by the ozone generator 200 and discharged into the vegetable compartment 120 .

In this way, the regulating member for adjusting the effect of the function additional device, that is, the cover member 210, is installed on the lower part of the heat insulating wall 115, that is, the ozone generating device 200 is closer to the vegetables by covering the ozone generating device 200 buried in the heat insulating wall 115. The inner side of the chamber 120 separates the storage space of the ozone generator 200 and the vegetable compartment 120 .

In addition, the cover member 210 adjusts the discharge amount and discharge range of ozone discharged into the vegetable compartment 120 by the ozone generator 200 by providing a plurality of suction holes 212 behind the lower surface.

Specifically, the lower surface of the cover member 210 , which is an adjustment member, forms a storage portion 210 a near the center without the discharge hole 211 , and the discharge hole 211 is arranged on the left and right sides of the storage portion 210 a. Therefore, the ozone generated by the ozone generator 200 is temporarily accumulated in the vicinity of the storage part 210a located near the center of the cover member 210, which is an adjustment member without the discharge hole 211, and ozone with a specific gravity heavier than air gradually diffuses to the lower surface of the cover member 210. The whole is discharged downward from the left and right discharge holes 211 arranged in the storage part 210a in a short time. Moreover, since the discharge hole 211 exists in multiple numbers, it can spread over the whole food storage 100.

On the other hand, the suction hole 212 arranged on the rear side of the center in the front-rear direction of the storage room mainly functions as a vent for sucking cold air from the outside of the cover member 210 for adjusting the function of the function adding device. In the case of the present embodiment, since the suction hole 212 is located in the vicinity of the cool air discharge port 213 described later, that is, on the rear side of the storage compartment, relatively dry cool air is sucked in. Therefore, the humidity of the upper side of the adjustment member, that is, the upper side of the cover member 210, that is, the inside of the cover member 210, can be kept low. The lower the humidity, the better the ozone generation efficiency of the ozone generating device 200, so the ozone generation efficiency can be maintained at a higher level. state. In addition to the introduction of these dry cold air, in the present embodiment, a cover is provided as an adjustment member in order to separate the food container 121, which is a storage space with high humidity due to the emission from vegetables, and the ozone generator 200. 210, the upper part of the cover member 210, that is, the periphery of the ozone generator 200 can be further maintained at a lower humidity, and the ozone generation efficiency can be maintained at a high state.

In addition, when ozone is generated by applying a high voltage to the ozone generator 200, in the temperature distribution in the storage room, since cool air flows in from the outside of the storage room, by installing an ozone generator near the cool air discharge port 213 at a low temperature, 200, the vicinity of the ozone generating device 200 becomes low temperature, and the lower the temperature, the higher the efficiency of ozone generation, so that ozone can be efficiently generated. Therefore, power consumption required for ozone generation can be suppressed, and the amount of ozone required can be generated, which contributes to energy saving, and also exhibits the effect of maintaining the freshness of ozone.

In addition, the cover part 210, which is used to adjust the function of the function additional device, can use the ozone generating efficiency of the ozone generating device 200, the amount of oxygen flowing into the cover part 210 through the suction hole 212, and the amount of ozone flowing out from the discharge hole 211. The relationship of , adjusts the ozone concentration of the vegetable compartment 120. That is, the adjusting member for adjusting the action of the function adding device can adjust the ozone concentration to some extent in consideration of the capacity of the vegetable compartment 120 by determining the total opening area of the discharge hole 211 provided in the adjusting member at the design stage. Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in vegetable compartment 120 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration of the vegetable compartment 120 up to the limit of the capacity of the ozone generator 200 . On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in vegetable compartment 120 decreases.

In addition, by designing the adjusting part, that is, the installation angle and position of the discharge hole 211 of the cover part 210, or making the cover part 210 movable, the discharge amount and discharge angle of the functional substance can be further adjusted, and the preservation can be improved more efficiently. functionality of the thing.

In addition, the adjustment member for adjusting the action of the function adding device described above flows out ozone and flows in oxygen by natural convection, but a fan may be used to forcibly flow out ozone and flow in oxygen. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the food container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone generation of the ozone generator 200 based on the information from the ozone concentration meter. amount to keep the ozone concentration in the food container 121 within a prescribed range.

It is preferable to maintain the ozone concentration in the vegetable compartment 120 and the food container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, when pulling out the food container 121 and taking out foods such as vegetables from containers such as the food container 121, some effects may be exerted on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to the unique odor of ozone.

In the present embodiment, the light source 220 is also provided as the function adding device, and therefore, the light source 220 irradiating light as the function adding device and the adjustment member for adjusting the light of the light source 220 will be described next.

The light source 220 has a function of promoting a biological defense reaction to increase functional components such as vitamin C contained in the food stored in the vegetable room 120 which is a storage room. In the case of this embodiment, LED is used as the light source 220 . LEDs have low calorific value, can prevent temperature rise in the storage space, can stabilize the preservation of food, and have low equipment operation costs. In addition, they have excellent durability and can be designed in a small size, so they are highly versatile and are preferably used in refrigerators. Specifications.

In addition, the light source 220 is arranged above the cover member 210 which is an adjustment member for adjusting the function of the function adding device, and is arranged so as to be surrounded by the cover member 210 . Thus, by separating the storage space in vegetable compartment 120 from the light source 220, it is possible to prevent the light source 220 from dew condensation due to the moisture in the vegetable compartment 120 with high humidity, thereby absorbing light of a predetermined wavelength, and the functional components Increased efficiency gets worse.

In this way, the irradiation adjustment unit 210b is also provided in the cover member 210 as an adjustment member that adjusts the light from the light source 220 . The irradiation adjustment unit 210b is preferably made of a material that sufficiently transmits light of a necessary wavelength among the light emitted from the light source 220 that is a function adding device. For example, any one of transparent resins that are light-transmitting resins such as epoxy resins, acrylic resins, polycarbonate resins, polyethylene resins, polystyrene resins, and polypropylene resins is used. Alternatively, a composite material obtained by combining a plurality of the above-mentioned translucent resins as a base material is preferable because it has diffusivity.

The wavelength radiated from the light source 220, which is the function adding device, is set to include a predetermined wavelength region that can promote the defense reaction of the living body and increase the functional components such as vitamin C and polyphenols in the food stored in the storage room.

Specifically, the wavelength range of the light source 220 is preferably a wavelength of 380nm to 800nm. For example, by including wavelengths in a range that is relatively safe for the human body, that is, wavelengths in the ultraviolet range of 280nm to 400nm, when the preserved objects are mushrooms, due to It contains a lot of ergosterol, which is a precursor substance of vitamin D. Therefore, by irradiating these substances with these wavelengths, the molecules are excited and converted into vitamin D. Therefore, the content of vitamin D can be increased and preserved, and the nutritional value can be improved. These effects are also the same in the case of fish, especially herring such as mackerel and sardines. In addition, polyphenols can be increased and preserved in anthocyanin-containing fruits and vegetables such as grapes, apples, and strawberries. Therefore, the functionality of food can be improved and preserved, and the functional value of the refrigerator can be improved.

In addition, pesticide residues attached to vegetables and fruits are irradiated with a light source including ultraviolet light to cause a photodecomposition reaction, which has the effect of reducing toxicity, so it can be stored more safely.

In addition, in particular, when blue light having a peak wavelength around 400nm to 500nm is used, it is possible to prevent degradation of synthetic resins, etc., which are commonly used in refrigerators, compared with ultraviolet wavelengths, etc. After quality deterioration such as lipid oxidation, as a unique effect of blue wavelengths, it also has the effect of inhibiting the growth of bacteria and mold, so it can keep the inside of the refrigerator and the surface of preserved objects or green fruits clean. In addition, the refreshing feeling of blue also has a sensory effect of giving the user a clean impression.

In addition, when using green light at a wavelength of 500nm to 600nm, it is possible to prevent deterioration of synthetic resins, etc., which are commonly used in refrigerators, compared to ultraviolet wavelengths, and as a unique effect of green wavelengths, light penetrates into the interior of green fruits, Therefore, it can act on the inside of the green fruit, promote the defense reaction of the living body from the inside side, and further increase nutrients such as vitamins.

Therefore, when a combination of blue wavelength and green wavelength light is emitted from the light source 220, the blue wavelength light can be used to inhibit the growth of bacteria on the surface of the green fruit, and the green wavelength that penetrates into the green fruit can be used to promote greenness. The living defense reaction inside the fruit can further improve the preservation of the green fruit.

In addition, regarding the irradiation method of the light source, the above-mentioned effect can be obtained even by continuous irradiation, but the stimulation will be stronger by flickering the light source, so in the blue light, the effect of inhibiting the growth of bacteria can be increased. , able to promote the living defense response on the surface of green fruits. Also, in green light, the living defense from the inside can be further promoted, so it is an effective method of irradiation.

In addition, in this embodiment, although LED is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, when a plurality of LEDs that emit light of different wavelengths are combined as the light source 220, more layers of effects can be obtained.

In addition, in the present embodiment, the storage room is divided into a plurality of storage sections by providing a plurality of storage containers inside the storage room. As shown in FIG. 19 , a food container 121 , which is the largest storage section among storage containers in the vegetable compartment 120 , and an upper container 123 installed above the food container 121 are provided, and these storage containers are divided into storage sections. The interior of the storage room is divided into a plurality of storage divisions, and the ozone generator 200 as a functional additional device and the cover member 210 as an adjustment member are located above the division with the largest capacity among the plurality of storage divisions. That is, the center of the vegetable compartment is slightly closer to the front. As a result, the ozone is not usually blocked by the upper container 123 used as a fruit box, and the ozone first diffuses in a wide range in the food container 121, which can improve the functionality of preserved objects more efficiently.

In addition, in this embodiment, the installation position of the light source 220 is arrange|positioned in the rear side of the vegetable compartment 120, and it is located in the upper side of the upper container 123 used as a fruit box. In this case, the upper container 123 is made of a translucent material. In this way, if it is a light-transmitting material, the influence of the container on diffusing is small. For example, if a gas such as ozone is convected and diffused together with cold air, it will physically collide with the container and hinder diffusion. In some cases, although there is a little refraction, the effect is less than that of the convective type with the cold air. By irradiating the food container 121 through the upper container 123, the light can be diffused to the storage area of the vegetable compartment 120. Therefore, the entire space does not need to be disposed directly above the food container 121 which is the largest storage division.

Moreover, the food storage 100 is provided with the cooling unit 140 which is not shown in figure. In the case of the present embodiment, cooling unit 140 is constituted by a cooling cycle including two coolers. Specifically, first cooler 112 is installed on the rear side of the inner surface of refrigerator compartment 110 . The inner surface of refrigerator compartment 110 is cooled by heat conduction from cooler 112 . The air in refrigerator compartment 110 is cooled by the cooled inner surface.

In addition, the second cooler 112 is installed on the rear side of the inner surface of the freezing compartment 130 . The inside of freezer compartment 130 is cooled by the cooled air that forcibly passes through second cooler 112 , and the cold air that has cooled food etc. returns to second cooler 112 again.

As shown in FIG. 18 , the cool air discharged from second cooler 112 is also supplied to vegetable compartment 120 through cool air outlet 213 . Vegetable compartment 120 controls the amount of cool air supplied by controlling the opening and closing of the damper, and maintains a temperature range between the temperature range of refrigerator compartment 110 and the temperature range of freezer compartment 130 . Specifically, it is controlled so as to maintain the temperature in the range of 4°C or lower and 0°C or higher.

In addition, when the cold air discharged from the second cooler 112 is supplied to the vegetable compartment 120 through the cold air discharge port 213, it is efficiently added with a function by function of a function adding device such as an ozone generator. In other words, ozone kills miscellaneous bacteria, and the airborne bacteria in the vegetable compartment 120 can be killed only by the diffusion of clean cold air into the vegetable compartment 120 . In addition, the cold air diffused into vegetable compartment 120 is cooled again by second cooler 112 outside freezer compartment 130 via suction port 214 . Therefore, in the vegetable compartment 120 and the freezer compartment 130 , ozone continues to circulate and is a very clean space, so food can be safely preserved.

Fig. 19 shows a food container and a lid.

The food container 121 is arranged in the vegetable compartment 120 which is a storage room with the upper container 123 arranged on the upper part, and is a drawable box body having an upper opening.

The lid 122 is a plate-shaped member that seals the openings of the food container 121 and the upper container 123, has a passage hole 124 and an adjustment hole 125, and functions as a second adjustment member. That is, in addition to the cover member 210 which is the first adjustment member, a cover 122 is installed as a second adjustment member on the inner side of the first adjustment member closer to the vegetable compartment 120 which is the storage room.

That is, after the ozone diffused through the adjustment member by the function of the ozone generator is further accumulated and filled in the upper part of the cover 122, it is further uniformly diffused into the food container from the passage hole 124 and the adjustment hole 125. In addition, since the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the light radiated from the light source 220, the effect on food by the light can be sufficiently maintained. In addition, the cover 122 has the function of adjusting the humidity in the food container 121 and the upper container 123, and specifically, keeps the moisture emitted from the vegetables stored in the food container 121 and the upper container 123 in the food container 121 to some extent. And in the upper container 123, the humidity is adjusted to the degree that the above-mentioned moisture does not condense in the food container 121 and the upper container 123.

In this way, in this embodiment, with respect to the ozone generating device 200 and the light source 220, which are the function adding devices, a plurality of adjustment members arranged to cover these function adding devices are provided, so that the ozone gas generated by the function adding devices, for example, Instead of being directly discharged into the storage room, it is discharged after passing through multiple adjustment components, so that the discharge amount and discharge range can be adjusted with better precision, and the functionality of the preserved objects in the storage room can be improved more efficiently.

In addition, in the present embodiment, the food container 121 is installed in the vegetable compartment 120, but the present embodiment is not limited thereto, and food may be directly stored in the vegetable compartment 120 without the food container 121 and its cover.

In addition, although the function adding device is an ozone generating device and an LED, the ultrasonic generator may be a device capable of adding various functions, such as a mist generating device that sprays mist.

Moreover, although the storage box 170 is divided by the fixed heat insulating wall 115, when it is not necessary to divide by a heat insulating wall in particular, you may divide by the partition wall which is not limited to a heat insulating material.

As mentioned above, with respect to the function adding device, the adjustment member arranged so as to cover these function adding devices is provided, so that the ozone gas generated by the function adding device, for example, is not directly discharged into the storage room, but is temporarily stored in the adjustment member. It is possible to easily adjust the discharge amount and discharge range by discharging in the internal space later, and to improve the functionality of the stored items in the storage room more efficiently.

(Embodiment 4-1)

Fig. 21 is a front view showing the food storage. As shown in the figure, the food storage 100 is a refrigerator provided with three doors 111a, 111b, 111c, and the storage room formed by the storage box 170 is divided into three.

The food storage 100 is provided with the refrigerator compartment 110, the vegetable compartment 120, and the freezer compartment 130 as the storage compartment divided from the upper part. In the same figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried into and out of the shelf-shaped storage box 170 from the front.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 includes a first door 111a that can open and close the refrigerator compartment 110, a second door 111b that can open and close the vegetable compartment 120, and a third door 111c that can open and close the freezer compartment 130. The doors 111a, 111b, and 111c pass through The hinge is installed on the storage box 170 in a switchable manner.

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

Fig. 22 is a longitudinal sectional view of food storage 100 according to the embodiment.

As shown in the figure, the food storage 100 is equipped with an ozone generator 200, and an isolation unit 210 (hereinafter referred to as a cover member 210 in this embodiment) as an adjustment member for adjusting the functions of a light source 220 and a function adding device. add-on. In addition, the food storage 100 installs the food container 121 and the cover 122 in the inside of the vegetable compartment 120 .

The ozone generator 200 which is a function adding device is a device capable of generating ozone to be supplied to the food container 121 arranged in the storage room. Ozone generator 200 is buried on the lower surface side of heat insulating wall 115 that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is arranged above the opening 127 of the food container 121 described later, at a position away from the opening 127 of the food container 121 , and at a position facing the opening 127 .

Thus, by embedding the ozone generator in the heat insulating wall 115, the temperature of the ozone generator 200 is hardly changed by the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

Fig. 23 is a sectional view of the refrigerator including the vicinity of the cover member 210, which is an adjustment member for adjusting the function of the functional attachment.

The regulating part for adjusting the effect of the function additional device is disposed on the inner side of the storage room of the function additional device, that is, the ozone generating device 200, and is a cover member 210 made of a thin plate that separates the ozone generating device 200 from the storage room, as shown in the figure 23 shows a cover member 210 in the shape of an inverted quadrangular truncated pyramid provided with a plurality of discharge holes 211 in front of the lower surface. In this case, cover member 210 , which is an adjustment member, has a plurality of discharge holes 211 to adjust the amount of ozone emitted from ozone generator 200 , which is a function adding device, into vegetable compartment 120 , which is a storage room. That is, the amount of ozone flowing into the vegetable compartment 120 is determined by the size and number of the discharge holes 211 . In addition, depending on the location where the discharge hole 211 is provided, it is possible to adjust the ozone emission range when the ozone is generated by the ozone generator 200 and discharged into the vegetable compartment 120 .

In this way, the regulating member for adjusting the effect of the function additional device, that is, the cover member 210, is installed on the lower part of the heat insulating wall 115, that is, the ozone generating device 200 is closer to the vegetables by covering the ozone generating device 200 buried in the heat insulating wall 115. The inner side of the chamber 120 separates the storage space of the ozone generator 200 and the vegetable compartment 120 .

In addition, the cover member 210 adjusts the discharge amount and discharge range of ozone discharged into the vegetable compartment 120 by the ozone generator 200 by providing a plurality of suction holes 212 behind the lower surface.

Specifically, the lower surface of the cover member 210 , which is an adjustment member, forms a storage portion 210 a near the center without the discharge hole 211 , and the discharge hole 211 is arranged on the left and right sides of the storage portion 210 a. Therefore, the ozone generated by the ozone generator 200 is temporarily accumulated in the vicinity of the storage part 210a located near the center of the cover member 210, which is an adjustment member without the discharge hole 211, and ozone with a specific gravity heavier than air gradually diffuses to the lower surface of the cover member 210. The whole is discharged downward from the left and right discharge holes 211 arranged in the storage part 210a in a short time. Moreover, since the discharge hole 211 exists in multiple numbers, it can spread over the whole food storage 100.

On the other hand, the suction hole 212 arranged on the rear side of the center in the front-rear direction of the storage room mainly functions as a vent for sucking cold air from the outside of the cover member 210 for adjusting the function of the function adding device. In the case of the present embodiment, since the suction hole 212 is located in the vicinity of the cool air discharge port 213 described later, that is, on the rear side of the storage compartment, relatively dry cool air is sucked in. Therefore, the humidity of the upper side of the adjustment member, that is, the upper side of the cover member 210, that is, the inside of the cover member 210, can be kept low. The lower the humidity, the better the ozone generation efficiency of the ozone generator 200, so the ozone generation efficiency can be maintained at a higher level. state. In addition to the introduction of these dry cold air, in the present embodiment, a cover is provided as an adjustment member in order to separate the food container 121, which is a storage space with high humidity due to the emission from vegetables, and the ozone generator 200. 210, the upper part of the cover member 210, that is, the periphery of the ozone generator 200 can be further maintained at a lower humidity, and the ozone generation efficiency can be maintained at a high state.

In addition, in the case where ozone is generated by applying a high voltage as the ozone generator 200, in the temperature distribution in the storage room, since cool air flows in from the outside of the storage room, the ozone generator is installed near the cold air discharge port 213 which becomes a low temperature. 200, the vicinity of the ozone generating device 200 becomes low temperature, and the lower the temperature, the higher the efficiency of ozone generation, so that ozone can be efficiently generated. Therefore, power consumption required for ozone generation can be suppressed, and the amount of ozone required can be generated, which contributes to energy saving, and also exhibits the effect of maintaining the freshness of ozone.

In addition, the cover part 210, which is used to adjust the function of the function additional device, can use the ozone generating efficiency of the ozone generating device 200, the amount of oxygen flowing into the cover part 210 through the suction hole 212, and the amount of ozone flowing out from the discharge hole 211. The relationship of , adjusts the ozone concentration of the vegetable compartment 120. That is, the adjusting member for adjusting the action of the function adding device can adjust the ozone concentration to some extent in consideration of the capacity of the vegetable compartment 120 by determining the total opening area of the discharge hole 211 provided in the adjusting member at the design stage. Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in vegetable compartment 120 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration of the vegetable compartment 120 up to the limit of the capacity of the ozone generator 200 . On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in vegetable compartment 120 decreases.

In addition, by designing the adjusting part, that is, the installation angle and position of the discharge hole 211 of the cover part 210, or making the cover part 210 movable, the discharge amount and discharge angle of the functional substance can be further adjusted, and the preservation can be improved more efficiently. functionality of the thing.

In addition, the adjustment member for adjusting the action of the function adding device described above flows out ozone and flows in oxygen by natural convection, but a fan may be used to forcibly flow out ozone and flow in oxygen. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the food container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone generation of the ozone generator 200 based on the information from the ozone concentration meter. amount to keep the ozone concentration in the food container 121 within a prescribed range.

It is preferable to maintain the ozone concentration in the vegetable compartment 120 and the food container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, when pulling out the food container 121 and taking out foods such as vegetables from containers such as the food container 121, some effects may be exerted on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to the unique odor of ozone.

In the present embodiment, the light source 220 is also provided as the function adding device, and therefore, the light source 220 irradiating light as the function adding device and the adjustment member for adjusting the light of the light source 220 will be described next.

The light source 220 has a function of promoting a biological defense reaction to increase functional components such as vitamin C contained in the food stored in the vegetable room 120 which is a storage room. In the case of this embodiment, LED is used as the light source 220 . LEDs have low calorific value, can prevent temperature rise in the storage space, can stabilize the preservation of food, and have low equipment operation costs. In addition, they have excellent durability and can be designed in a small size, so they are highly versatile and are preferably used in refrigerators. Specifications.

In addition, the light source 220 is arranged above the cover member 210 which is an adjustment member for adjusting the function of the function adding device, and is arranged so as to be surrounded by the cover member 210 . Thus, by separating the storage space in vegetable compartment 120 from the light source 220, it is possible to prevent the light source 220 from dew condensation due to the moisture in the vegetable compartment 120 with high humidity, thereby absorbing light of a predetermined wavelength, and the functional components Increased efficiency gets worse.

In this way, the irradiation adjustment unit 210b is also provided in the cover member 210 as an adjustment member that adjusts the light from the light source 220 . The irradiation adjustment unit 210b is preferably made of a material that sufficiently transmits light of a necessary wavelength among the light emitted from the light source 220 that is a function adding device. For example, any one of transparent resins that are light-transmitting resins such as epoxy resins, acrylic resins, polycarbonate resins, polyethylene resins, polystyrene resins, and polypropylene resins is used. Alternatively, a composite material obtained by combining a plurality of the above-mentioned translucent resins as a base material is preferable because it has diffusivity.

The wavelength radiated from the light source 220, which is the function adding device, is set to include a predetermined wavelength region that can promote the defense reaction of the living body and increase the functional components such as vitamin C and polyphenols in the food stored in the storage room.

Specifically, the wavelength range of the light source 220 is preferably a wavelength of 380nm to 800nm. For example, by including wavelengths in a range that is relatively safe for the human body, that is, wavelengths in the ultraviolet range of 280nm to 400nm, when the preserved objects are mushrooms, due to It contains a lot of ergosterol, which is a precursor substance of vitamin D. Therefore, by irradiating these substances with these wavelengths, the molecules are excited and converted into vitamin D. Therefore, the content of vitamin D can be increased and preserved, and the nutritional value can be improved. These effects are also the same in the case of fish, especially herring such as mackerel and sardines. In addition, polyphenols can be increased and preserved in anthocyanin-containing fruits and vegetables such as grapes, apples, and strawberries. Therefore, the functionality of food can be improved and preserved, and the functional value of the refrigerator can be improved.

In addition, pesticide residues attached to vegetables and fruits are irradiated with a light source including ultraviolet light to cause a photodecomposition reaction, which has the effect of reducing toxicity, so it can be stored more safely.

In addition, in particular, when blue light having a peak wavelength around 400nm to 500nm is used, it is possible to prevent degradation of synthetic resins, etc., which are commonly used in refrigerators, compared with ultraviolet wavelengths, etc. After quality deterioration such as lipid oxidation, as a unique effect of blue wavelengths, it also has the effect of inhibiting the growth of bacteria and mold, so it can keep the inside of the refrigerator and the surface of preserved objects or green fruits clean. In addition, the refreshing feeling of blue also has a sensory effect of giving the user a clean impression.

In addition, when using green light at a wavelength of 500nm to 600nm, it is possible to prevent deterioration of synthetic resins, etc., which are commonly used in refrigerators, compared to ultraviolet wavelengths, and as a unique effect of green wavelengths, light penetrates into the interior of green fruits, Therefore, it can act on the inside of the green fruit, promote the defense reaction of the living body from the inside side, and further increase nutrients such as vitamins.

Therefore, when a combination of blue wavelength and green wavelength light is emitted from the light source 220, the blue wavelength light can be used to inhibit the growth of bacteria on the surface of the green fruit, and the green wavelength that penetrates into the green fruit can be used to promote greenness. The living defense reaction inside the fruit can further improve the preservation of the green fruit.

In addition, regarding the irradiation method of the light source, the above-mentioned effect can be obtained even by continuous irradiation, but the stimulation will be stronger by flickering the light source, so in the blue light, the effect of inhibiting the growth of bacteria can be increased. , able to promote the living defense response on the surface of green fruits. Also, in green light, the living defense from the inside can be further promoted, so it is an effective method of irradiation.

In addition, in this embodiment, although LED is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, when a plurality of LEDs that emit light of different wavelengths are combined as the light source 220, more layers of effects can be obtained.

In addition, in the present embodiment, the storage room is divided into a plurality of storage sections by providing a plurality of storage containers inside the storage room. As shown in FIG. 25 , it includes food container 121 , which is the largest storage section among storage containers in vegetable compartment 120 , and upper container 123 mounted on top of food container 121 , and these storage containers are divided into storage sections. The interior of the storage room is divided into a plurality of storage divisions, and the ozone generator 200 as a functional additional device and the cover member 210 as an adjustment member are located above the division with the largest capacity among the plurality of storage divisions. That is, the center of the vegetable compartment is slightly closer to the front. As a result, the ozone is not usually blocked by the upper container 123 used as a fruit box, and the ozone first diffuses in a wide range in the food container 121, which can improve the functionality of preserved objects more efficiently.

In addition, in this embodiment, the installation position of the light source 220 is arrange|positioned in the rear side of the vegetable compartment 120, and it is located in the upper side of the upper container 123 used as a fruit box. In this case, the upper container 123 is made of a translucent material. In this way, if it is a light-transmitting material, the influence of the container on diffusing is small. For example, if the gas such as ozone and cold air are convected and diffused together, they will physically collide with the container and hinder diffusion. In this case, although there is a little refraction, the effect is smaller than that of the convection type with the function of the additional device functioning together with the air conditioner. By irradiating the food container 121 through the upper container 123, the light can be diffused to the storage area of the vegetable compartment 120. Therefore, the entire space does not need to be disposed directly above the food container 121 which is the largest storage division.

Moreover, the food storage 100 is provided with the cooling unit 140 which is not shown in figure. In the case of the present embodiment, cooling unit 140 is constituted by a cooling cycle including two coolers. Specifically, first cooler 112 is installed on the rear side of the inner surface of refrigerator compartment 110 . The inner surface of refrigerator compartment 110 is cooled by heat conduction from cooler 112 . The air in refrigerator compartment 110 is cooled by the cooled inner surface.

In addition, the second cooler 112 is installed on the rear side of the inner surface of the freezing compartment 130 . The inside of freezer compartment 130 is cooled by the cooled air that forcibly passes through second cooler 112 , and the cold air that has cooled food etc. returns to second cooler 112 again.

As shown in FIG. 24 , the cool air discharged from second cooler 112 is also supplied to vegetable compartment 120 through cool air outlet 213 . Vegetable compartment 120 controls the amount of cool air supplied by controlling the opening and closing of the damper, and maintains a temperature range between the temperature range of refrigerator compartment 110 and the temperature range of freezer compartment 130 . Specifically, it is controlled so as to maintain the temperature in the range of 4°C or lower and 0°C or higher.

In addition, when the cold air discharged from the second cooler 112 is supplied to the vegetable compartment 120 through the cold air discharge port 213, it is efficiently added with a function by function of a function adding device such as an ozone generator. In other words, ozone kills miscellaneous bacteria, and the airborne bacteria in the vegetable compartment 120 can be killed only by the diffusion of clean cold air into the vegetable compartment 120 . In addition, the cold air diffused into vegetable compartment 120 is cooled again by second cooler 112 outside freezer compartment 130 via suction port 214 . Therefore, in the vegetable compartment 120 and the freezer compartment 130 , ozone continues to circulate and is a very clean space, so food can be safely preserved.

Fig. 25 shows a food container and a lid.

The food container 121 is arranged in the vegetable compartment 120 which is a storage room with the upper container 123 arranged on the upper part, and is a drawable box body having an upper opening.

The lid 122 is a plate-shaped member that seals the openings of the food container 121 and the upper container 123, has a passage hole 124 and an adjustment hole 125, and functions as a second adjustment member. That is, in addition to the cover member 210 which is the first adjustment member, a cover 122 is installed as a second adjustment member on the inner side of the first adjustment member closer to the vegetable compartment 120 which is the storage room.

That is, after the ozone diffused through the adjustment member by the function of the ozone generator is further accumulated and filled in the upper part of the cover 122, it is further uniformly diffused into the food container from the passage hole 124 and the adjustment hole 125. In addition, since the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the light radiated from the light source 220, the effect on food by the light can be sufficiently maintained. In addition, the cover 122 has the function of adjusting the humidity in the food container 121 and the upper container 123, and specifically, keeps the moisture emitted from the vegetables stored in the food container 121 and the upper container 123 in the food container 121 to some extent. And in the upper container 123, the humidity is adjusted to the degree that the above-mentioned moisture does not condense in the food container 121 and the upper container 123.

In this way, in this embodiment, with respect to the ozone generating device 200 and the light source 220, which are the function adding devices, a plurality of adjustment members arranged to cover these function adding devices are provided, so that the ozone gas generated by the function adding devices, for example, Instead of being directly discharged into the storage room, it is discharged after passing through multiple adjustment components, so that the discharge amount and discharge range can be adjusted with better precision, and the functionality of the preserved objects in the storage room can be improved more efficiently.

In addition, in the present embodiment, the food container 121 is installed in the vegetable compartment 120, but the present embodiment is not limited thereto, and food may be directly stored in the vegetable compartment 120 without the food container 121 and its cover.

In addition, although the function adding device is an ozone generator or an LED, the ultrasonic generator may also be a device capable of adding various functions, such as a mist generating device that sprays mist.

Moreover, although the storage box 170 is divided by the fixed heat insulating wall 115, when it is not necessary to divide by a heat insulating wall in particular, you may divide by the partition wall which is not limited to a heat insulating material.

(Embodiment 4-2)

Fig. 26 is a perspective view of the state in which the door of the refrigerator of Embodiment 4-2 is removed, and Fig. 27 is a longitudinal sectional view of the refrigerator compartment of the refrigerator of the same embodiment.

As shown in Fig. 26 and Fig. 27, the refrigerator of this embodiment is divided into a freezer compartment 303 and a refrigerator compartment 304 by a freezer compartment 301 and a refrigerator compartment 302, and a storage compressor (not shown) is installed at the bottom of the back. Shown) and the refrigerator main body 307 of the mechanical room 306 of the condenser 305, and the freezer door (not shown) of the hinge switch type and the refrigerator door 308, and a refrigeration system is installed inside, and the refrigeration system is composed of Compressor, condenser 305, switching valve (not shown), first decompression device (not shown), second decompression device (not shown), refrigerating evaporator (not shown), refrigerating evaporator The container 309 is constituted, and refrigerants such as hydrocarbon gas are sealed inside.

Inside the refrigerating room 304, a first compartment 310, a second compartment 311, a third compartment 312, a first storage box 313, a second storage box 314, and a third storage box 315 are installed to divide the interior of the refrigerating room 304. Divide into seven.

In addition, a cooling air passage 316 and a fan 317 for circulating cold air in the refrigerator compartment 304 are installed on the back of the refrigerating chamber 304. The cooling air passage 316 has a first outlet 318, a second outlet 319, and a second outlet 319 for blowing out cold air. The third blowing port 320 and the fourth blowing port 321, and the first suction port 322, the second suction port 323, and the third suction port 324 for sucking return air.

In addition, a partition plate 326 is installed on the third storage box 315 top to substantially seal the opening 325 of the third storage box 315, and an ozone generator 327 is installed on the partition plate 326 as a function additional device, and for The cover member 329 is an adjustment member that adjusts the actions of the light source 328 and the function additional device.

The operation|movement of the refrigerator comprised as mentioned above is demonstrated below.

During the operation of the refrigerator, the high-temperature and high-pressure refrigerant compressed by the compressor is cooled and condensed by the condenser 305 to become a liquid refrigerant. The refrigerant condensed by the condenser 305 flows to the first decompression device or the second decompression device for decompression through the switching valve, and becomes a low-pressure and low-temperature gas-liquid two-phase refrigerant.

Here, the refrigerant flowing to the first decompression device flows in the refrigerating evaporator, evaporates in the freezing compartment 303, cools the inside of the freezing compartment 303 by the heat of evaporation, and is sucked into the compressor.

In addition, the refrigerant flowing to the second decompression device through the switching valve flows from the refrigerating evaporator 309 to the freezing evaporator, evaporates in the refrigerating chamber 304 and the freezing chamber 303, and cools the refrigerating chamber 304 and the freezing chamber 303 by the heat of evaporation. inside, and then sucked in by the compressor.

Here, the cold air obtained by the heat of evaporation of the liquid refrigerant in the refrigerating evaporator 309 passes through the fan 317, flows in the cooling air passage 316, and is blown from the first outlet 318, the second outlet 319, and the third outlet. The outlet 320 and the fourth outlet 321 blow out, thereby cooling each partition.

Moreover, the inside of the 2nd storage box 314 and the 3rd storage box 315 is cooled by the return air which cooled the division|segment other than that, flowing inside and outside a box.

Moreover, the relatively high-temperature return air sucked in from the first suction port 322, the second suction port 323, and the third suction port 324 evaporates the liquid refrigerant in the refrigerating evaporator 309 through the temperature difference, and absorbs heat to become The low temperature is introduced into the box by the fan 317 to cool each division. The ozone generator 327 which is a function adding device is a device capable of generating ozone to be supplied to the third storage box 315 arranged in the storage room. Ozone generated by the ozone generator 327 tends to accumulate on the lower surface of the third storage box 315 because the molecular weight of the ozone is heavier than that of air, and the third storage box 315 is more likely to be filled.

Here, the ozone generator 327 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

FIG. 28 is a cross-sectional view of the third storage box 315 including the vicinity of the cover member 329 which is an adjustment member for adjusting the function of the function attachment. FIG. 29 is a cross-sectional view of a cover member 329 as an adjustment member.

The regulating part that is used to regulate the effect of function additional device is arranged in the inner side of the storage room of function additional device namely ozone generator 327, is the cover member 329 that is made of sheet that separates ozone generator 327 and storage room, as shown in the figure 29 shows a cover member 329 in the shape of an inverted quadrangular truncated pyramid provided with a plurality of discharge holes 331 in front of the lower surface. In this case, cover member 329 , which is an adjustment member, has a plurality of discharge holes 331 , so that the amount of ozone generated by ozone generator 327 , which is a function adding device, can be adjusted to discharge into third storage box 315 , which is a storage room. That is, the amount of ozone flowing into the third storage box 315 is determined by the size and number of the discharge holes 331 . In addition, depending on the position where the discharge hole 331 is installed, the ozone discharge range when the ozone generator 327 is generated and discharged into the third storage box 315 can be adjusted. Like this, be used for regulating the effect of function additional device, namely the cover member 329 is arranged in the third storage box 315 interior side of the ozone generation device 327 as function additional device embedded in partition plate 326, and light source 328, passes to cover The ozone generating device 327 and the light source 328 are installed in a manner to separate the ozone generating device 327 from the storage space of the third storage box 315 .

In addition, the cover member 329 adjusts the discharge amount and discharge range of ozone discharged into the third storage box 315 by the ozone generator 327 by providing a plurality of suction holes 332 behind the lower surface.

Specifically, the lower surface of the cover member 329 , which is an adjustment member, forms a storage portion 329 a near the center without the discharge hole 331 , and the discharge hole 331 is arranged on the left and right sides of the storage portion 329 a. Therefore, the ozone generated by the ozone generator 327 temporarily accumulates near the storage portion 329a near the center of the cover member 329, which is an adjustment member without the discharge hole 331, and the ozone with a specific gravity heavier than air gradually diffuses to the lower surface of the cover member 329. The whole is discharged downward from the left and right discharge holes 331 arranged in the storage part 329a in a short time. Moreover, since the discharge hole 331 exists in multiple numbers, it can spread over the whole food storage 100.

On the other hand, the suction hole 332 arranged on the rear side of the center in the front-rear direction of the storage compartment mainly functions as a vent for sucking cold air from the outside of the cover member 329 for adjusting the function of the function adding device. In the case of Embodiment 4-2, since the suction hole 332 is located in the vicinity of the cool air discharge port 321 described later, that is, on the rear side of the storage compartment, relatively dry cool air is sucked in. Therefore, the humidity of the upper side of the adjustment member, that is, the upper side of the cover member 329, that is, the inside of the cover member 329, can be kept low. The lower the humidity, the better the ozone generation efficiency of the ozone generator 327, so the ozone generation efficiency can be maintained at a higher level. state. In addition to the introduction of these dry cold air, in this embodiment 4-2, the third storage box 315 and the ozone generating device 200 are also separated from each other by separating the third storage box 315, which is a storage space with high humidity due to the emission from the vegetables. By providing the cover member 329 which is an adjustment member, the upper part of the cover member 329, that is, the periphery of the ozone generator 327 can be kept at a lower humidity, and the ozone generation efficiency can be maintained at a high level.

In addition, when ozone is generated by applying a high voltage to the ozone generator 327, in the temperature distribution in the storage room, since cool air flows in from the outside of the storage room, by installing an ozone generator near the cold air discharge port 321 at a low temperature, 327, the vicinity of the ozone generating device 327 becomes low temperature, and the lower the temperature, the higher the efficiency of ozone generation, so ozone can be efficiently generated. Therefore, power consumption required for ozone generation can be suppressed, and the amount of ozone required can be generated, which contributes to energy saving, and also exhibits the effect of maintaining the freshness of ozone.

In addition, the regulating part for adjusting the effect of the function additional device, that is, the cover part 329 can use the ozone generation efficiency of the ozone generating device 327, the amount of oxygen flowing into the cover part 329 through the suction hole 332, and the amount of ozone flowing out from the discharge hole 331. The relationship between adjusts the ozone concentration in the third storage box 315. That is, the adjusting member for adjusting the function of the function adding device can adjust the ozone concentration to some extent by considering the capacity of the third storage box 315 by determining the total opening area of the discharge hole 331 provided in the adjusting member at the design stage. Specifically, when there are many discharge holes 331 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the third storage box 315 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 331 is proportional to the ozone concentration of the third storage box 315 up to the limit of the capacity of the ozone generator 327 . On the contrary, when there are few discharge holes 331 (the total opening area is small), the outflow of ozone decreases, and the ozone concentration in the third storage box 315 decreases.

In addition, by designing the adjusting part, that is, the installation angle and position of the discharge hole 331 of the cover part 329, or making the cover part 329 movable, the discharge amount and discharge angle of the functional substance can be further adjusted, and the preservation can be improved more efficiently. functionality of the thing.

In addition, the adjustment member for adjusting the action of the function adding device described above flows out ozone and flows in oxygen by natural convection, but a fan may be used to forcibly flow out ozone and flow in oxygen. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the third storage box 315, and adjust (for example, ON and OFF of the above-mentioned fan) the operation of the ozone generator 327 based on the information from the ozone concentration meter. The amount of ozone generated keeps the ozone concentration in the third storage box 315 within a predetermined range.

The ozone concentration of the third storage box 315 is preferably maintained at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, when taking out food such as vegetables, it may have some influence on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to the unique odor of ozone. However, the ozone concentration is not limited to this.

In Embodiment 4-2, the light source 328 is further provided as the function adding device, so the light source 328 irradiating light as the function adding device and the adjustment member for adjusting the light of the light source 328 will be described next.

The light source 328 has a function of promoting a biological defense reaction to increase functional components such as vitamin C contained in the food stored in the third storage box 315 which is the storage room. In the case of Embodiment 4-2, LEDs are used as the light source 328 . LEDs have low calorific value, can prevent temperature rise in the storage space, can stabilize the preservation of food, and have low equipment operation costs. In addition, they have excellent durability and can be designed in a small size, so they are highly versatile and are preferably used in refrigerators. Specifications.

In addition, the light source 328 is disposed above a cover member 329 that is an adjustment member for adjusting the function of the function-added device, and is arranged so as to be surrounded by the cover member 329 . Thus, by separating the storage space in the third storage box 315 from the light source 328, it is possible to prevent the light source 328 from dew condensation due to moisture in the high-humidity third storage box 315, thereby absorbing light of a predetermined wavelength. The increase efficiency of the functional ingredient becomes worse.

In this manner, the cover member 329 also includes the irradiation adjustment unit 329 b as an adjustment member that adjusts the light from the light source 328 . The irradiation adjustment unit 329b is preferably made of a material that sufficiently transmits light of a necessary wavelength among the light emitted from the light source 328 which is a function adding device. For example, any one of transparent resins that are light-transmitting resins such as epoxy resins, acrylic resins, polycarbonate resins, polyethylene resins, polystyrene resins, and polypropylene resins is used. Alternatively, a composite material obtained by combining a plurality of the above-mentioned translucent resins as a base material is preferable because it has diffusivity.

The wavelength emitted from the light source 328, which is a function adding device, is set to include a predetermined wavelength region that can promote the defense reaction of the living body and increase the functional components such as vitamin C and polyphenols in the food stored in the storage room.

Specifically, the wavelength range of the light source 328 is preferably a wavelength of 380nm to 800nm. For example, by including wavelengths in a range that is relatively safe for the human body, that is, wavelengths in the ultraviolet region of 280nm to 400nm, when the preserved objects are mushrooms, because It contains a lot of ergosterol, which is a precursor substance of vitamin D. Therefore, by irradiating these substances with these wavelengths, the molecules are excited and converted into vitamin D. Therefore, the content of vitamin D can be increased and preserved, and the nutritional value can be improved. These effects are also the same in the case of fish, especially herring such as mackerel and sardines. In addition, polyphenols can be increased and preserved in anthocyanin-containing fruits and vegetables such as grapes, apples, and strawberries. Therefore, the functionality of food can be improved and preserved, and the functional value of the refrigerator can be improved.

In addition, pesticide residues attached to vegetables and fruits are irradiated with a light source including ultraviolet light to cause a photodecomposition reaction, which has the effect of reducing toxicity, so it can be stored more safely.

In addition, in particular, when blue light having a peak wavelength around 400nm to 500nm is used, it is possible to prevent degradation of synthetic resins, etc., which are commonly used in refrigerators, compared with ultraviolet wavelengths, etc. After quality deterioration such as lipid oxidation, as a unique effect of blue wavelengths, it also has the effect of inhibiting the growth of bacteria and mold, so it can keep the inside of the refrigerator and the surface of preserved objects or green fruits clean. In addition, the refreshing feeling of blue also has a sensory effect of giving the user a clean impression.

In addition, when using green light at a wavelength of 500nm to 600nm, it is possible to prevent deterioration of synthetic resins, etc., which are commonly used in refrigerators, compared to ultraviolet wavelengths, and as a unique effect of green wavelengths, light penetrates into the interior of green fruits, Therefore, it can act on the inside of the green fruit, promote the defense reaction of the living body from the inside side, and further increase nutrients such as vitamins.

Therefore, when a combination of blue wavelength and green wavelength light is emitted from the light source 328, the propagation of bacteria on the surface of the green fruit can be suppressed by the light of the blue wavelength, and the green color can be promoted by the green wavelength penetrating into the green fruit. The living defense reaction inside the fruit can further improve the preservation of the green fruit.

In addition, regarding the irradiation method of the light source, the above-mentioned effect can be obtained even by continuous irradiation, but the stimulation will be stronger by flickering the light source, so in the blue light, the effect of inhibiting the growth of bacteria can be increased. , able to promote the living defense response on the surface of green fruits. Also, in green light, the living defense from the inside can be further promoted, so it is an effective method of irradiation.

In addition, in this embodiment, although LED is used as the light source 328, it is not limited to this in particular, The light source 328 which emits the light of a continuous spectrum may be sufficient. In addition, when a plurality of LEDs that emit light of different wavelengths are combined as the light source 328, more layers of effects can be obtained.

In this way, in the present embodiment 4-2, with respect to the ozone generating device 327 and the light source 328, which are the function adding devices, a plurality of adjustment members arranged to cover these function adding devices are provided, so that no damage will be caused by the function adding devices. For example, ozone gas, etc. are directly discharged into the storage room, but are discharged after passing through multiple adjustment parts, so that the discharge amount and discharge range can be adjusted with better precision, and the functionality of the preserved objects in the storage room can be improved more efficiently. .

In addition, although the function adding device is an ozone generator or an LED, the ultrasonic generator may also be a device capable of adding various functions, such as a mist generating device that sprays mist.

In this way, with respect to the function adding device, the adjustment member arranged to cover these function adding devices is provided, so that the ozone gas generated by the function adding device, for example, is not directly discharged into the storage room, but is temporarily stored in the inside of the adjustment member. After entering the space, the discharge is performed, so that the discharge amount and discharge range can be easily adjusted, and the functionality of the stored items in the storage room can be improved more efficiently.

(Embodiment 5)

The present embodiment relates to a food storage including a refrigerator, and particularly relates to a food storage that can spread ozone over the entire storage room divided into upper and lower sections.

Currently, ozone having a strong oxidizing effect is used for sterilization and mold prevention in refrigerators and the like. For example, the refrigerator described in (Japanese) Patent Document 2: Japanese Laid-Open No. 2001-91146 has a drawer-type container in the refrigerator, and a small container called a so-called fruit box is provided on the top of the container. Furthermore, an ozone generating device is provided above and below the container, and sterilization and antibacterial of the inside of the container are performed by ozone.

However, as a result of research conducted by the present inventors, it was found that in the refrigerator described in Patent Document 2, when containers are arranged in two stages up and down, the effect of ozone does not spread over the entire container in two stages. And find out, because ozone is relatively heavy, it is easy to accumulate in the bottom of one side container, and ozone does not spread to another container.

This embodiment is embodiment based on the result of the said study, and it aims at providing the food storage which can diffuse ozone as a whole even if it is equipped with the storage room divided into upper and lower two stages.

In order to achieve the above objects, the food storage of this embodiment is characterized by comprising: a storage box forming a storage room for storing food, a door for opening and closing the storage box, and an ozone generating device that generates ozone supplied to the storage room. The ozone generating device of the patio part of the storage box is arranged in the upper interior of the storage room where the ozone can be received, and the first container has an outflow hole for the ozone below.

According to this, the ozone generated by the ozone generator is received in the first container arranged above, but flows out from the outflow port and flows into the storage room arranged below, so that the ozone can be distributed throughout the space divided up and down.

In addition, a second container is provided, the second container is disposed below the first container, supports the first container, is drawable with respect to the storage room, and has an opening that opens upward, and the outflow hole is preferably arranged At the point where the ozone flows out to the second container.

Thereby, foods of different sizes can be separately stored up and down, and the flow path of ozone can be prevented from being closed by smaller foods being sandwiched between larger food gaps, and it is easy to take out and put in foods.

In addition, the first container is a box-shaped container with an open upper surface, and the outflow hole is preferably provided on a peripheral wall of the first container.

According to this, even if many foods are stored in the first container, it is possible to prevent the outflow hole from being clogged by foods. Therefore, even in the case of storing many foods, ozone can be spread throughout the whole.

Moreover, it is preferable that the said outflow hole is provided in the bottom part of a 1st container, and it communicates with the said outflow hole provided in the said surrounding wall.

Accordingly, when the amount of food stored in the first container is small, ozone will easily flow out from the outflow hole arranged at the bottom, and when the amount of food is large, the outflow hole arranged at the bottom will be blocked by the food, and ozone will only flow out from the outflow hole on the wall. . Therefore, the outflow amount of ozone can be adjusted by the amount of food stored in the first container, and ozone can be spread evenly.

In this embodiment, ozone can be spread throughout the entire space divided up and down.

Next, embodiment of the food storage of this embodiment is demonstrated with reference to drawings. In addition, this embodiment is not limited to this embodiment.

FIG. 31 is a front view showing a food storage in Embodiment 5. FIG.

As shown in the figure, the food storage 100 is a refrigerator provided with three doors 111, and the storage room formed by the storage box 170 is divided into three.

The food storage 100 is provided with the refrigerator compartment 110, the vegetable compartment 120, and the freezer compartment 130 as the storage compartment divided from the upper part. In the same figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried into and out of the shelf-shaped storage box 170 from the front.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 has a first door 111a that can open and close the refrigerator compartment 110, a second door 111b that can open and close the vegetable compartment 120, and a third door 111c that can open and close the freezer compartment 130, and the door 111 can be opened and closed by hinges. Installed on the storage box 170 ground.

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

Fig. 32 is a longitudinal sectional view of food storage 100 according to this embodiment.

As shown in the figure, the food storage 100 is equipped with the ozone generator 200, the isolation unit 210, and the light source 220. In addition, the food storage 100 is equipped with an upper container 123 (hereinafter referred to as a first container 123 in this embodiment) and a food container 121 (hereinafter referred to as a second container in this embodiment) in the vegetable compartment 120 . 121), cover 122.

The ozone generator 200 is a device capable of generating ozone supplied to the first container 123 and the second container 121 arranged in the storage room. Ozone generator 200 is embedded on the lower surface of heat insulating wall 115 (hereinafter referred to as shelf 115 in this embodiment) that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is disposed above the opening 127 of the second container 121 described later, at a position away from the opening 127 of the second container 121 , and at a position facing the opening 127 .

Thus, by embedding the ozone generator in the shelf 115, the temperature of the ozone generator 200 is hardly changed due to the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

The isolation unit 210 is a part made of a thin plate that separates the ozone generator 200 from the storage room. As shown in FIG. . The isolation unit 210 is attached to the lower surface of the shelf 115 so as to cover the ozone generator 200 embedded in the shelf 115 , and isolates the ozone generator 200 from the vegetable compartment 120 . In addition, the isolation unit 210 is provided with a plurality of suction holes 212 in front of the lower face.

The lower surface of the partition unit 210 is inclined so as to descend toward the rear position of the food storage 100, and the discharge hole 211 is arranged near the lowest position.

Accordingly, ozone having a specific gravity heavier than air is mainly discharged downward from the discharge hole 211 . On the other hand, the suction hole 212 disposed in the front mainly functions as a hole for sucking in the atmosphere outside the isolation unit 210 . In the case of the present embodiment, the suction hole 212 sucks the cool air discharged from the cool air discharge port 213 described later and passed along the outer wall of the second container 121 .

In addition, the isolation unit 210 can adjust the ozone concentration of the vegetable compartment 120 according to the relationship between the ozone generation efficiency of the ozone generator 200, the amount of oxygen flowing into the isolation unit 210 through the suction hole 212, and the amount of ozone flowing out of the discharge hole 211. That is, the isolation unit 210 can adjust the ozone concentration of the first container 123 and the second container 121 to a certain extent by determining the total opening area of the discharge hole 211 and the total opening area of the suction hole 212 arranged in the isolation unit 210 at the design stage. . Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the first container 123 and the second container 121 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration in the first container 123 and the second container 121 up to the limit of the capacity of the ozone generator 200. On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in the first container 123 and the second container 121 decreases.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the second container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone concentration of the ozone generator 200 based on the information from the ozone concentration meter. The generated amount keeps the ozone concentration in the second container 121 within a predetermined range.

It is preferable to maintain the ozone concentration in the first container 123 and the second container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, pulling out the second container 121 and taking out foods such as vegetables from the second container 121 may have some influence on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

The light source 220 is a device that emits light of a predetermined wavelength that can promote the decomposition of pesticides by ozone for food stored in the vegetable compartment 120 that is a storage compartment. In the case of this embodiment, a light emitting diode (LED) is used as the light source 220 .

In addition, the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

In addition, the wavelength emitted by the light source 220 is a predetermined wavelength that can promote the decomposition of pesticides by ozone on food stored in the storage room, and may be included in any wavelength region of the infrared region, visible region, and ultraviolet region.

Specifically, it is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide, and this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, wavelengths corresponding to valleys of the spectrum, such as the wavelength of the portion with the strongest absorption capability, are preferable. For example, a wavelength specified by the infrared absorption spectrum of chlorpyrifos, or malathion, or quinathion-type pesticides is preferable. The reason is that these pesticides are commonly used in foods and have a high possibility of remaining in foods.

On the other hand, it may be a wavelength activated by ozone. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if activated by ozone, it promotes the decomposition of pesticides.

In addition, the light emitting method of the light source 220 may be a method that easily decomposes pesticides. For example, consider a method in which light source 220 is continuously turned on only when the ozone concentration of vegetable compartment 120 is equal to or higher than a predetermined value. In consideration of the decomposition efficiency of the pesticide, the above-mentioned predetermined value is preferably 0.01 ppm or more. In addition, the light source 220 may be blinked at an emission interval corresponding to a multiple or a submultiple of the natural frequency of the molecules constituting the agricultural chemical. From this, it is considered that light energy can be more efficiently injected into the pesticide, and the pesticide can be easily decomposed by ozone.

In addition, in this embodiment, although a light emitting diode is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, as the light source 220, a plurality of light emitting diodes that emit lights of different wavelengths may be used in combination.

Moreover, the food storage 100 is equipped with the cooling unit 140. As shown in FIG. In the case of the present embodiment, cooling unit 140 is constituted by a cooling cycle including two coolers. Specifically, first cooler 112 is installed on the rear side of the inner surface of refrigerator compartment 110 . The inner surface of refrigerator compartment 110 is cooled by heat conduction from cooler 112 . The air in refrigerator compartment 110 is cooled by the cooled inner surface.

In addition, the second cooler 112 is installed on the rear side of the inner surface of the freezing compartment 130 . The inside of freezer compartment 130 is cooled by the cooled air that forcibly passes through second cooler 112 , and the cold air that has cooled food etc. returns to second cooler 112 again.

The cool air discharged from second cooler 112 is also supplied to vegetable compartment 120 through cool air outlet 213 . Vegetable compartment 120 controls the amount of cool air supplied by controlling the opening and closing of the damper, and maintains a temperature range between the temperature range of refrigerator compartment 110 and the temperature range of freezer compartment 130 . Specifically, it is controlled so as to maintain the temperature in the range of 4°C or lower and 0°C or higher.

Fig. 34 is a perspective view showing a first container, a second container and a cap.

The first container 123 is a box arranged in the upper part of the vegetable room 120 which is a storage room, that is, a position where ozone discharged from the ozone generator 200 is received, and is a container called a so-called fruit box. In the case of the present embodiment, the first container 123 is supported behind the upper part of the second container 121 described later in a stored state, and can be pulled out and pushed into the vegetable compartment 120 together with the second container 121 . In addition, the first container 123 is provided with a plurality of outflow holes 128 through which ozone flows through in the thickness direction from the lower portion of the front wall, which is one of the peripheral walls, to the bottom. In addition, the first container 123 is made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

The second container 121 is disposed in the vegetable compartment 120 which is a storage room, and is a drawable box having an opening 127 opening upward. In addition, the side surface, bottom surface, and inner surface of the second container 121 are integrally molded with white resin, and the front surface is molded with transparent resin and fixed. Therefore, in the state which opened the 2nd door 111b, even if the 2nd container 121 is not pulled out, the inside of the 2nd container 121 can be seen through the front part, and food storage can also be confirmed.

The lid 122 is a plate-shaped member that seals the upper openings 127 of the first container 123 and the second container 121 , and includes a passage hole 124 and an adjustment hole 125 . In addition, the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the light radiated from the light source 220 . The lid 122 has the function of adjusting the humidity in the first container 123 and the second container 121, specifically, it maintains the moisture emitted from the vegetables and fruits stored in the first container 123 and the second container 121 to a certain extent. In the first container 123 and the second container 121 , the humidity is adjusted at the same time to such an extent that the moisture does not condense in the first container 123 and the second container 121 .

The passage hole 124 is mainly a hole having a function of passing ozone, and is a hole penetrating through the cover 122 in the thickness direction. In addition, as shown in FIG. 35A , the passing hole 124 has a conical shape whose diameter gradually expands upward. In addition, since the passage hole 124 is the hole that introduces the ozone generated by the ozone generating device 200 into the first container 123, it is therefore arranged directly below the discharge hole 211 provided on the isolation unit 210 and the area around it (the discharge hole corresponds to the position 126 (Refer to FIG. 34)).

By forming the passage hole 124 in such a shape, the part of the passage hole 124 with a large diameter catches the ozone falling from the discharge hole 211 of the isolation unit 210 , and the ozone can be efficiently introduced into the first container 123 . On the other hand, the moisture existing in the first container 123 and the second container 121 can be consistent with the outflow of the adjustment hole 125 described later, and the humidity inside the second container 121 can be adjusted according to the design concept.

The adjustment hole 125 is a through-shaped hole provided in a portion other than the discharge hole corresponding position 126, and is provided to adjust the state of the atmosphere (especially moisture) inside the first container 123 and the second container 121 to adjust the internal atmosphere. Part of the function that exhausts air to the outside. As shown in FIG. 35B , the adjustment hole 125 is a hole penetrating through the cover 122 in the thickness direction. In addition, the number and size of the adjustment holes 125 are determined in the design stage according to the range to be adjusted (eg, the range of humidity in the second container 121 ).

As mentioned above, the food storage 100 of this embodiment first introduces the ozone discharged from the ozone generator 200 into the first container 123, and then leads it out to the second container 123 from the outflow hole 128 provided on the lower part and bottom of the peripheral wall of the first container 123. Two containers 121. Therefore, the ozone is not only stored in the first container 123 , but the ozone can be distributed to the second container 121 as a whole.

Moreover, by providing the outflow hole 128 at the corner connecting the peripheral wall and the bottom of the first container 123 , it is possible to efficiently flow ozone to the second container 121 below. In addition, it is assumed that the food stored in the first container 123 is fruit. Fruit is spherical mostly, if outflow hole 128 is set at the corner of first container 123, then can avoid that outflow hole 128 is blocked because of food.

In addition, since the cold air from the cooling unit 140 will not directly flow into the second container 121, there will be no large convection inside the second container 121, and in addition, the internal air of the second container 121 will not flow to the outside in large quantities. Therefore, it is possible to create a state where the ozone existing in the second container 121 sufficiently acts on the surface of the stored food. In addition, when the food is irradiated with light from the light source 220, the pesticide remaining on the surface of the food can be efficiently decomposed by the composite effect of ozone and light.

In addition, in this embodiment, the second container 121 and the cover 122 are installed in the vegetable compartment 120, but the present embodiment is not limited thereto, and the second container 121 and the cover 122 may be disposed above the vegetable compartment 120. The first container 123 .

In addition, as shown in FIG. 36A, the outflow hole 128 may exist independently in the peripheral wall and the bottom. In addition, as shown in FIG. 36B , a notch may be cut in the upper part of the surrounding wall as the outflow hole 128 .

The present embodiment can be applied to a food storage room in which the storage room is divided into upper and lower sections, and in particular, can be applied to a storage box or a refrigerator for storing food.

(Embodiment 6)

This embodiment relates to a food storage including a refrigerator, and particularly relates to a food storage including an ozone generator.

Currently, ozone having a strong oxidizing effect is used for sterilization and mold prevention in refrigerators and the like. For example, in (Japanese) Patent Document 2: Japanese Unexamined Publication No. 2001-91146, as shown in FIG. 42 , an ozone generator is directly installed on the cover 122 of a food container 121 that can be drawn and stored in the vegetable compartment of the refrigerator. device 200. And by arranging the ozone generator 200 in the opening part of the food container 121 in this way, it can suppress that the ozone density|concentration in the food container 121 falls, and can perform microbe elimination and antibacterial efficiently.

However, when an ozone generator is arranged at the opening of a food container, water vapor emitted from food, especially vegetables, will adversely affect the ozone generator, slowing down the efficiency of ozone generation. Therefore, it is difficult to maintain the required ozone concentration in the food container, and a large amount of power consumption is required to maintain the required ozone concentration.

This embodiment was made in view of the said subject, and it aims at providing the food storage which can suppress the influence of the water vapor discharged|emitted from food, and can make a storage room into necessary ozone concentration.

In order to achieve the above objects, the food storage of this embodiment is characterized by comprising: a storage box forming a storage room for storing food and having an opening in the front; a door for opening and closing the storage box; and an ozone generator that generates ozone supplied to the storage room. The generating device is an ozone generating device installed on the patio of the storage box, an isolation unit for isolating the ozone generating device from the storage room, and a discharge hole provided in the isolation unit through which ozone generated by the ozone generating device passes.

In this way, the storage room for storing food is isolated from the ozone generating device, and the ozone generating device is arranged in an isolated state above the space for storing food, so the ozone generating device can be protected by the influence of moisture emitted from the food, and ozone can be generated The ozone generating efficiency of the device is maintained at a high level.

In addition, a drawable food container having an opening opening upward is provided in the storage room, and the ozone generator is preferably disposed at a position facing the opening away from the opening.

As a result, the ozone generator is placed above the food container for storing food in an isolated state, so the ozone generator can be protected by the influence of moisture emitted from the food, and the ozone generation efficiency of the ozone generator can be maintained at a high level. .

In addition, a cover for sealing the opening of the above-mentioned food container is provided, and the above-mentioned cover preferably includes: a passage hole provided at a position corresponding to the above-mentioned discharge hole through which ozone passes; Discharge to external adjustment hole.

According to this, ozone can be introduced into the food container, and at the same time, the state inside the food container, such as humidity, can be adjusted. Therefore, it is also possible to maintain the ozone concentration and humidity in the food container in an arbitrary state.

The passage hole preferably has a shape in which an opening area of the lower portion of the cover is smaller than an opening area of the upper portion of the cover.

Thereby, the ozone which falls from the ozone generator arrange|positioned above can be efficiently collected, and can be introduced into a food container. In addition, it is also possible to suppress the amount of atmosphere that flows out from the inside of the food container through the passage hole.

According to this embodiment, the food storage which can suppress the influence of the humidity in a storage room and maintain stable ozone generation efficiency can be provided.

Next, embodiment of the food storage of this embodiment is demonstrated with reference to drawings. In addition, this embodiment is not limited to this embodiment.

FIG. 37 is a front view showing a food storage in Embodiment 6. FIG.

As shown in the figure, the food storage 100 is a refrigerator provided with three doors 111, and the storage room formed by the storage box 170 is divided into three.

The food storage 100 is provided with the refrigerator compartment 110, the vegetable compartment 120, and the freezer compartment 130 as the storage compartment divided from the upper part. In the same figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried into and out of the shelf-shaped storage box 170 from the front.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 includes a first door 111a that can open and close the refrigerator compartment 110, a second door 111b that can open and close the vegetable compartment 120, and a third door 111c that can open and close the freezer compartment 130. The door 111 can be opened and closed by a hinge. Installed in the storage box 170 .

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

Fig. 38 is a longitudinal sectional view of food storage 100 according to this embodiment.

As shown in the figure, the food storage 100 is equipped with the ozone generator 200, the isolation unit 210, and the light source 220. Moreover, the food storage 100 is equipped with the food container 121 and the cover 122 in the inside of the vegetable compartment 120. As shown in FIG.

The ozone generator 200 is a device capable of generating ozone to be supplied to the food container 121 arranged in the storage room. Ozone generator 200 is embedded on the lower surface of heat insulating wall 115 (hereinafter referred to as shelf 115 in this embodiment) that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is arranged above the opening 127 of the food container 121 described later, at a position away from the opening 127 of the food container 121 , and at a position facing the opening 127 .

Thus, by embedding the ozone generator in the shelf 115, the temperature of the ozone generator 200 is hardly changed due to the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

The isolation unit 210 is a part made of a thin plate that separates the ozone generating device 200 from the storage room. As shown in FIG. . The isolation unit 210 is attached to the lower surface of the shelf 115 so as to cover the ozone generator 200 embedded in the shelf 115 , and isolates the ozone generator 200 from the vegetable compartment 120 . In addition, the isolation unit 210 is provided with a plurality of suction holes 212 behind the lower surface.

The lower surface of the partition unit 210 is inclined so as to descend toward the regular position of the food storage 100, and the discharge hole 211 is arranged near the lowest position.

Accordingly, ozone having a specific gravity heavier than air is mainly discharged downward from the discharge hole 211 . On the other hand, the suction hole 212 disposed at the rear mainly functions as a hole for sucking in the atmosphere outside the isolation unit 210 . In the case of the present embodiment, since the suction hole 212 is located near a cool air discharge port 213 described later, cool air in a relatively dry state is sucked in. Therefore, the humidity inside the isolation unit 210 can be kept low, and the ozone generation efficiency of the ozone generator 200 can be maintained in a high state. Moreover, when the type of the ozone generator 200 is a type which generates ozone by high voltage, since the inside of the isolation|separation unit 210 becomes low temperature, ozone can generate|occur|produce efficiently. Therefore, power consumption necessary for ozone generation can be suppressed, and energy saving can be contributed.

In addition, the isolation unit 210 can adjust the ozone concentration of the vegetable compartment 120 according to the relationship between the ozone generation efficiency of the ozone generator 200, the amount of oxygen flowing into the isolation unit 210 through the suction hole 212, and the amount of ozone flowing out of the discharge hole 211. That is, the isolation unit 210 can adjust the ozone concentration of the vegetable compartment 120 to some extent by determining the total opening area of the discharge hole 211 and the total opening area of the suction hole 212 provided in the isolation unit 210 at the design stage. Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in vegetable compartment 120 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration of the vegetable compartment 120 up to the limit of the capacity of the ozone generator 200 . On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in vegetable compartment 120 decreases.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the food container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone generation of the ozone generator 200 based on the information from the ozone concentration meter. amount to keep the ozone concentration in the food container 121 within a prescribed range.

It is preferable to maintain the ozone concentration in the vegetable compartment 120 and the food container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, pulling out the food container 121 and taking out food such as vegetables from the food container 121 may have some influence on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

The light source 220 is a device that emits light of a predetermined wavelength that can promote the decomposition of pesticides by ozone for food stored in the vegetable compartment 120 that is a storage compartment. In the case of this embodiment, a light emitting diode (LED) is used as the light source 220 .

In addition, the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that sufficiently transmits light of a necessary wavelength among the light emitted from the light source 220 .

In addition, the wavelength emitted by the light source 220 is a predetermined wavelength that can promote the decomposition of pesticides by ozone on food stored in the storage room, and may be included in any wavelength region of the infrared region, visible region, and ultraviolet region.

Specifically, it is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide, and this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, wavelengths corresponding to valleys of the spectrum, such as the wavelength of the portion with the strongest absorption capability, are preferable. For example, a wavelength specified by the infrared absorption spectrum of chlorpyrifos, or malathion, or quinathion-type pesticides is preferable. The reason is that these pesticides are commonly used in foods and have a high possibility of remaining in foods.

On the other hand, it may be a wavelength activated by ozone. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if activated by ozone, it promotes the decomposition of pesticides.

In addition, the light emitting method of the light source 220 may be a method that easily decomposes pesticides. For example, consider a method of continuously lighting light source 220 only when the ozone concentration of vegetable compartment 120 is equal to or higher than a predetermined value. In consideration of the decomposition efficiency of the pesticide, the above-mentioned predetermined value is preferably 0.01 ppm or more. Alternatively, the light source 220 may be blinked at light emission intervals corresponding to multiples or submultiples of the natural frequency of the molecules constituting the pesticide. From this, it is considered that light energy can be more efficiently injected into the pesticide, and the pesticide can be easily decomposed by ozone.

The LEDs of the light source 220 can also be fixed on the shelf 115 or on the isolation unit 210 . In the case of being fixed to the isolation unit 210 , an LED substrate (not shown) for controlling the LEDs is also fixed to the isolation unit 210 .

In addition, in this embodiment, although a light emitting diode is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, as the light source 220, a plurality of light emitting diodes that emit lights of different wavelengths may be used in combination.

Moreover, the food storage 100 is equipped with the cooling unit 140. As shown in FIG. In the case of the present embodiment, cooling unit 140 is constituted by a cooling cycle including two coolers. Specifically, first cooler 112 is installed on the rear side of the inner surface of refrigerator compartment 110 . The inner surface of refrigerator compartment 110 is cooled by heat conduction from cooler 112 . The air in refrigerator compartment 110 is cooled by the cooled inner surface.

In addition, the second cooler 112 is installed on the rear side of the inner surface of the freezing compartment 130 . The inside of freezer compartment 130 is cooled by the cooled air that forcibly passes through second cooler 112 , and the cold air that has cooled food etc. returns to second cooler 112 again.

The cool air discharged from second cooler 112 is also supplied to vegetable compartment 120 through cool air outlet 213 . Vegetable compartment 120 controls the amount of cool air supplied by controlling the opening and closing of the damper, and maintains a temperature range between the temperature range of refrigerator compartment 110 and the temperature range of freezer compartment 130 . Specifically, it is controlled so as to maintain the temperature in the range of 4°C or lower and 0°C or higher.

Fig. 40 is a perspective view showing a food container and a lid.

The food container 121 is arranged in the vegetable compartment 120 which is a storage room, and is a drawable box having an opening 127 opened upward.

The lid 122 is a plate-like member that seals the opening 127 of the food container 121 and includes a passage hole 124 and an adjustment hole 125 . The lid 122 has the function of adjusting the humidity in the food container 121. Specifically, the moisture emitted from the vegetables stored in the food container 121 is maintained in the food container 121 to a certain extent, and the humidity is adjusted to the above-mentioned humidity at the same time. The degree to which dew does not condense in the food container 121 .

The passage hole 124 is a hole mainly having a function of passing ozone, and is a hole penetrating through the cover 122 in the thickness direction. In addition, as shown in FIG. 41A , the passing hole 124 has a conical shape whose diameter gradually expands upward. In addition, the passage hole 124 is a hole that introduces the ozone generated by the ozone generating device 200 into the food container 121 inside, so it is arranged directly below the discharge hole 211 provided on the isolation unit 210 and the area around it (the corresponding position of the discharge hole 126 (refer to Figure 40)).

By forming the passing hole 124 in such a shape, the large diameter part of the passing hole 124 can catch the ozone falling from the discharge hole 211 of the partition unit 210, and the ozone can be efficiently introduced into the food container 121. On the other hand, the moisture present in the food container 121 can be consistent with the outflow of the adjustment hole 125 described later, and the humidity inside the food container 121 can be adjusted according to the design concept.

The adjustment hole 125 is a through-shaped hole provided in a portion other than the discharge hole corresponding position 126, and has a function of discharging the internal atmosphere to the outside in order to adjust the state of the atmosphere (especially moisture) inside the food container. part. As shown in FIG. 41B , the adjustment hole 125 is a hole penetrating through the cover 122 in the thickness direction. In addition, the number and size of the adjustment holes 125 are determined according to the range to be adjusted (for example, the range of humidity in the food container 121 ) at the design stage.

As described above, the food storage 100 of the present embodiment can easily decompose the agricultural chemicals remaining in the stored food by the power of light and decompose the agricultural chemicals by the oxidizing power of ozone, so the agricultural chemicals can be efficiently decomposed. Therefore, even if the ozone concentration in the storage room is suppressed to a range that does not affect the human body, residual pesticides can be decomposed. In addition, since pesticides can be decomposed even in an environment below 4°C where the activity of pesticides is low, food can be stored for a long time and residual pesticides can be decomposed.

In addition, since ethylene gas can also be reduced, especially food such as vegetables can be prevented from being deteriorated such as browning.

In addition, in this embodiment, the adjustment hole 125 is provided only in the lid 122, but the adjustment hole 125 may be provided in the wall surface of the food container 121.

This embodiment can be applied to a food storage with the functions of sterilization and antibacterial achieved by ozone, especially to a refrigerator.

(Embodiment 7)

This embodiment relates to a food storage including a refrigerator, and particularly relates to a food storage in which a storage room is divided into three temperature zones.

At present, most food storages such as refrigerators are divided into a refrigerator room with the highest set temperature zone, a freezer room with the lowest set temperature zone, and a vegetable room with a set temperature zone slightly lower than the refrigerator room according to the purpose of storage.

In this case, since the temperature ranges of the refrigerator compartment and the vegetable compartment are close, a single air passage is used to cool the refrigerator compartment and the vegetable compartment, and the freezer compartment is independently cooled (refer to (Japanese) Patent Document 2: JP-A-2001-91146).

On the other hand, ozone may be used as a measure against bacteria and mold in food storage. For example, the air blowing unit for a refrigerator described in Patent Document 2 blows the air cooled by the cooler into the refrigerator compartment, and introduces the cold air after cooling the refrigerator compartment into the vegetable compartment. Furthermore, the ozone generating device is arranged in the lower part of the vegetable compartment, and the ozone rides on the cold air blown by the above-mentioned air blowing unit and spreads over the entire refrigerator compartment and the vegetable compartment, thereby performing sterilization and mildew prevention.

However, the present inventors have conducted studies and experiments and found that in the configuration in which the ozone generator is installed in the vegetable room with the highest temperature in the circulation path of the cold air blown from the cooler to the refrigerator room via the vegetable room and returned to the cooler, when When ozone is generated, there is a part where the sterilization and antifungal effects cannot be obtained. In addition, it has also been found that the energy efficiency of the ozone generator is poor in the above configuration.

This embodiment was completed based on the above insight of the inventor's research results, and an object thereof is to provide a food storage that can efficiently generate ozone, prolong the life of ozone, and realize the effect of ozone in a wide range.

In order to achieve the above objects, the food storage of this embodiment is characterized by comprising: a storage box forming a storage room for storing food; room, the door for opening and closing the storage box, the first cooler for cooling the air in the first storage room, the second cooler for cooling the air in the freezer compartment and the second storage room, and the cold air cooled by the second cooler An air blowing unit blowing to the freezer compartment and the second storage compartment, and an ozone generating device for generating ozone supplied to a cool air ventilation passage, which is a path through which the cool air passes through the second storage compartment.

Accordingly, the ozone generator can supply ozone to the relatively low-temperature cold air cooled by the second cooler applicable to the freezer, prolong the life of ozone, and supply ozone throughout the entire second storage room. In addition, even if ozone is not generated in a large amount, ozone can be distributed throughout the second cooling chamber, so generation of ozone does not consume a lot of energy, and the effect of ozone can be efficiently obtained.

Moreover, it is preferable that the said ozone generator is embedded in the said partition wall, and is arrange|positioned in the said cool air ventilation path.

Thereby, the ozone generating device is not corroded, and the storage space can be kept spacious. In addition, the blown cold air does not directly contact the ozone generator, but indirectly cools the ozone generator. In this state, since the electric loss of the ozone generating device is reduced (due to a reduction in electrical resistance), ozone can be efficiently generated, which contributes to energy saving. In addition, since the ozone generating device is embedded in the partition wall, the temperature can be kept low even when cold air is not flowing, and ozone can be efficiently generated.

In addition, the second cooler is an element constituting a cooling cycle device using a refrigerant, and the refrigerant may be a flammable refrigerant.

Accordingly, a flammable refrigerant is preferable because the influence on the environment can be suppressed and can be handled even when the food storage is exhausted. In addition, in case the refrigerant leaks and flows together with the cold air, the ozone generating device having a high voltage generating part and the refrigerant will not be in direct contact, and since the ozone generating device is buried in the partition wall, the explosion and damage can be promptly reduced. Possibility of fire.

In this embodiment, ozone can be efficiently generated, and the effect of ozone can be obtained over the entire second storage room.

Next, embodiment of the food storage of this embodiment is demonstrated with reference to drawings. In addition, this embodiment is not limited to this embodiment.

FIG. 43 is a front view showing a food storage in Embodiment 7. FIG.

As shown in the figure, the food storage room 100 is a refrigerator provided with a storage box 170 and three doors 111, and the storage room formed inside the storage box 170 is divided into a refrigerator room 110 (in this embodiment, hereinafter, described as a first room). storage room 110 ), vegetable room 120 (in this embodiment, hereinafter, described as second storage room 120 ), and freezer room 130 .

In the same figure, the rectangular dotted line of the food storage room 100 indicates the openings of the first storage room 110, the second storage room 120, and the freezer room 130, and the object of storage, that is, food, is carried into the first storage room 110, which is divided into shelf shapes, from the front. In the second storage room 120 and the freezer room 130, it can also be taken out.

The function (cooling temperature) of the 1st storage room 110, the 2nd storage room 120, and the freezing room 130 differs according to the foods to store.

The first storage room 110 is a storage room set at a temperature such that stored items do not freeze for refrigerated storage. The lower limit of the specific temperature is usually set at 1 to 5°C.

The second storage room 120 is mainly intended for refrigeration of vegetables, and is a storage room kept at a low temperature such that storage items (vegetables) do not freeze, and is a so-called vegetable room. In addition, the temperature setting of the second storage room 120 is equal to or slightly higher than that of the first storage room 110 . The lower limit of the specific temperature is 2°C to 7°C. In addition, the lower the temperature, the longer the freshness of the leafy vegetables can be maintained.

Freezer room 130 is a storage room set in a freezing temperature zone. Specifically, it is usually set at -22 to -18°C for cryopreservation, but may be set at a low temperature of, for example, -30°C or -25°C in order to improve the state of cryopreservation.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 has a first door 111a that can open and close the first storage room 110, a second door 111b that can open and close the second storage room 120, and a third door 111c that can open and close the freezer compartment 130. The pages are attached to the storage box 170 in a switchable manner.

The heat insulating wall 115 (in this embodiment, hereinafter, described as the partition wall 115) is a plate-shaped member for partitioning the first storage room 110 and the second storage room 120, as shown in the figure, inside the storage box 170 It is integrally formed into a shelf shape. Moreover, the same partition wall 115 is provided also between the 2nd storage room 120 and the freezer room 130. As shown in FIG.

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

The partition wall 115 has a structure in which a heat insulating material made of foamed resin is sandwiched between two thin plates made of the same resin as the inner box 171 .

Fig. 44 is a longitudinal sectional view showing the food storage.

As shown in the figure, the food storage 100 is equipped with the ozone generator 200, the isolation unit 210, and the light source 220. In addition, the food storage 100 is equipped with an upper container 123 (hereinafter referred to as the first container 123 in this embodiment) and a food container 121 (hereinafter referred to as the second container 123 in the present embodiment) inside the second storage room 120 . Two containers 121), cover 122.

The ozone generator 200 is a device capable of generating ozone supplied to the first container 123 and the second container 121 arranged in the storage room. The ozone generator 200 is buried in the lower surface side of the partition wall 115 which partitions the 1st storage room 110 and the 2nd storage room 120 toward the inside of the 2nd storage room 120. As shown in FIG.

The ozone generator 200 includes a booster (not shown) that boosts a supplied power supply voltage, and an ozone generator (not shown) that generates ozone from oxygen in the air by arranging a high-potential terminal in space.

In addition, the ozone generator 200 is not limited to the above. Specifically, examples include a device for generating ozone (O ₃ ) by irradiating ultraviolet light to oxygen molecules (O ₂ ) in the air, and a device for supplying ozone into air by electrolysis of oxygen-containing substances such as water.

The isolation unit 210 is a component made of a thin plate that separates the ozone generating device 200 from the cold air ventilation passage 175 described later. As shown in FIG. A hood in the shape of a truncated pyramid. Isolation unit 210 is attached to the lower surface of partition wall 115 so as to cover ozone generator 200 embedded in partition wall 115 , and partitions ozone generator 200 from cool air passage 175 . In addition, the isolation unit 210 is provided with a plurality of suction holes 212 in front of the lower face.

The lower surface of the partition unit 210 is inclined so as to descend toward the rear position of the food storage 100, and the discharge hole 211 is arranged near the lowest position.

The cool air passage 175 means the main passage of cool air blown from the cooling chamber 114 by the blower unit 113 described later, and in the present embodiment, there are no members actively forming the cool air passage 175 such as ducts. Therefore, a part of the space in the second storage room 120 becomes the cold air ventilation path 175 .

Thus, since the second storage room 120 and the ozone generator 200 are partitioned and arranged by the isolation unit 210 , the cool air passing through the cool air ventilation path 175 does not directly contact the ozone generator 200 . Therefore, even if the flammable refrigerant leaks, it will not come into direct contact with the ozone generator 200 generating a high voltage, so the risk of explosion can be avoided.

In addition, since the ozone generator 200 is buried in the partition wall 115 and covered with the partition unit 210, the temperature of the cooled ozone generator 200 is hard to rise, and ozone can be efficiently generated.

In addition, in this embodiment, the cold air ventilation passage 175 and the ozone generator 200 are separated by tangible components, but this embodiment need not be limited thereto, as long as the cold air ventilation passage 175 and the ozone generator 200 are separated, it is not necessarily necessary to physically separate the air passage 175 from the ozone generator 200. separate parts.

In addition, the isolation unit 210 can adjust the ozone concentration of the second storage chamber 120 according to the relationship between the ozone generation efficiency of the ozone generator 200, the amount of oxygen flowing into the isolation unit 210 through the suction hole 212, and the amount of ozone flowing out of the discharge hole 211. That is, the isolation unit 210 can adjust the ozone inside the first container 123 and the second container 121 to a certain extent by determining the total opening area of the discharge hole 211 and the total opening area of the suction hole 212 provided in the isolation unit 210 at the design stage. concentration. Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the first container 123 and the second container 121 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration in the first container 123 and the second container 121 up to the limit of the capacity of the ozone generator 200. On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in the first container 123 and the second container 121 decreases.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, based on a signal from the control board 132 , the movement and stop of the fan may be controlled. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the second container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone concentration of the ozone generator 200 based on the information from the ozone concentration meter. The generated amount keeps the ozone concentration in the second container 121 within a predetermined range.

It is preferable to maintain the ozone concentration in the first container 123 and the second container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, pulling out the second container 121 and taking out foods such as vegetables from the second container 121 may have some influence on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

The light source 220 is a device that emits light of a predetermined wavelength that can promote decomposition of chemical substances such as pesticides by ozone on food stored in the second storage room 120 , which is a storage room. In the case of this embodiment, a light emitting diode (LED) is used as the light source 220 .

In addition, the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

In this way, when light is activated while maintaining a predetermined ozone concentration, the effect of sterilization and mold prevention is more than that, for example, the decomposition of agricultural chemicals can be carried out by ozone.

In addition, the wavelength emitted by the light source 220 is a predetermined wavelength that can promote the decomposition of pesticides by ozone on food stored in the storage room, and may be included in any wavelength region of the infrared region, visible region, and ultraviolet region.

Specifically, it is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide, and this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, wavelengths corresponding to valleys of the spectrum, such as the wavelength of the portion with the strongest absorption capability, are preferable. For example, a wavelength specified by the infrared absorption spectrum of chlorpyrifos, or malathion, or quinathion-type pesticides is preferable. The reason is that these pesticides are commonly used in foods and have a high possibility of remaining in foods.

On the other hand, it may be a wavelength activated by ozone. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if activated by ozone, it promotes the decomposition of pesticides.

In addition, the light emitting method of the light source 220 may be a method that easily decomposes pesticides. For example, consider a mode in which light source 220 is continuously turned on only when the ozone concentration in second storage room 120 is equal to or higher than a predetermined value. In consideration of the decomposition efficiency of the pesticide, the above-mentioned predetermined value is preferably 0.01 ppm or more. Alternatively, the light source 220 may be blinked at light emission intervals corresponding to multiples or submultiples of the natural frequency of the molecules constituting the pesticide. From this, it is considered that light energy can be more efficiently injected into the pesticide, and the pesticide can be easily decomposed by ozone.

In addition, in this embodiment, although a light emitting diode is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, as the light source 220, a plurality of light emitting diodes that emit lights of different wavelengths may be used in combination.

Moreover, the food storage 100 is equipped with the cooling unit 119, the ventilation unit 113, the damper 131 (in this embodiment, it describes below as the control valve 131), and the control board|substrate 132.

The cooling unit 119 is a device that discharges the heat in the storage room to the outside of the storage room through a cooling cycle. It is composed of a cooler, a radiator, a compressor, etc., and discharges the heat existing in one side to the other side through the evaporation and condensation of the refrigerant. refrigerant circuit configuration.

As shown in FIG. 44 , the cooling unit 119 includes two coolers, a first cooler 112a and a second cooler 112b.

Second cooler 112 b is attached to cooling room 114 provided on the back side of the inner surface of freezing room 130 , and cools the air introduced into freezing room 130 and second storage room 120 in cooling room 114 .

The first cooler 112 a is disposed on the back side of the first storage room 110 , and cools the first storage room 110 by directly exchanging heat with air in the first storage room 110 .

Air blower unit 113 blows the air cooled by second cooler 112 b to freezer compartment 130 and second storage compartment 120 . In the case of the present embodiment, an axial fan is used as the blower unit 113 .

The regulator valve 131 is a damper for adjusting the amount of cold air (air cooled by the second cooler 112b) blown by the blower unit 113 and discharged out of the second storage room 120, and can be adjusted by controlling the opening degree of the valve including full closing. to adjust.

The cold air cooled by the second cooler 112 b is cooled in the freezer compartment 130 and has a sufficiently low temperature, so that it cannot be continuously discharged into the second storage compartment 120 . Therefore, the discharge amount of the cold air to the second storage room 120 is adjusted by adjusting the valve 131, and the temperature of the second storage room 120 is maintained at a predetermined temperature (0° C. to 4° C.).

In addition, the second storage room 120 can also function as a freezing room if the set temperature is lowered and the regulator valve 131 is kept open for a long time.

The control board 132 is electrically connected to the cooling unit 119, the blower unit 113, the regulating valve 131, sensors (not shown), and is a board for controlling the above-mentioned devices.

Fig. 46 is a perspective view showing a first container, a second container and a cap.

The 1st container 123 is what is called a so-called fruit box arrange|positioned in the inner upper part of the 2nd storage room 120 which is a storage room. In the case of the present embodiment, the first container 123 is supported behind the upper part of the second container 121 described later in a stored state, and can be pulled out and pushed into the second storage room 120 together with the second container 121 . In addition, the first container 123 is provided with a plurality of outflow holes 128 through which ozone flows through in the thickness direction from the lower portion of the front wall, which is one of the peripheral walls, to the bottom. In addition, the first container 123 is made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

The second container 121 is disposed in the second storage room 120 which is a storage room, and is a drawable box having an opening 127 opening upward.

The lid 122 is a plate-shaped member that seals the upper openings 127 of the first container 123 and the second container 121 , and includes a passage hole 124 . In addition, the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the light radiated from the light source 220 . The lid 122 has the function of adjusting the humidity in the first container 123 and the second container 121, specifically, it maintains the moisture emitted from the vegetables and fruits stored in the first container 123 and the second container 121 to a certain extent. In the first container 123 and the second container 121 , the humidity is adjusted at the same time to such an extent that the moisture does not condense in the first container 123 and the second container 121 .

The passage hole 124 is a through hole, and is a portion having a function of discharging the internal atmosphere to the outside in order to adjust the state of the atmosphere (especially moisture) inside the first container 123 and the second container 121 . In addition, it also has the function of introducing cold air and ozone outside the second container 121 into the inside of the second container 121 .

If adopt the above structure, then the ozone supplied by the ozone generating device 200 is supplied to the cold air cooled by the second cooler 112b which can cool the freezer compartment 130, so the life of the ozone can be improved, and a sufficient amount of ozone can be spread throughout the second cooler. The entire interior of the storage room 120 . Therefore, sterilization and mold prevention effects can be achieved by ozone. In addition, since the second storage room 120 as a whole has a sufficient ozone concentration, chemical substances such as pesticides remaining in food can be decomposed by recombination with light from the light source 220 .

In addition, the cold air cooled by the second cooler 112b becomes cold air in a dry state because the second cooler 112b condenses and removes moisture. Therefore, even if ozone is mixed into the cool air, the ozone will not be decomposed into oxygen by moisture, and the high ozone concentration can be maintained continuously.

In addition, since the ozone generator 200 is indirectly cooled by the cold air, the efficiency of ozone generation is improved, and sufficient ozone can be generated even if the input energy is reduced.

This embodiment can be applied to a food storage, especially a refrigerator.

(Embodiment 8)

The present embodiment relates to a food storage including a refrigerator, and particularly relates to a food storage capable of decomposing pesticides remaining in food.

Currently, ozone having a strong oxidizing effect is used for sterilization and mold prevention in refrigerators and the like. For example, (Japanese) Patent Document 1: Patent No. 3920064 discloses an invention related to a refrigerator that is constructed on the premise of using ozone for sterilization and mold prevention, and is configured to prevent corrosion like the ozone. The resin of the inner surface of the refrigerator is formed with an ozone-resistant material. In addition, Patent Document 1 has a description that ultraviolet rays are irradiated to a photocatalyst arranged in the refrigerator, and odor components are decomposed by the catalyst to perform deodorization.

At present, pesticide residues in food are a problem, and it is desirable to reduce pesticide residues in food during food storage, but there is no proposal related to food storage that can effectively decompose chemical substances such as pesticide residues.

Therefore, the present inventors focused on detoxification of chemical substances such as pesticides widely used in refrigerators and the like through ozonolysis, and obtained the following insights as a result of studies. That is, chemical substances such as pesticides can be decomposed if high-concentration ozone that does not affect the human body is used, but it is difficult to decompose pesticides with ozone concentrations that can be applied to food storage such as refrigerators that people frequently open and close. In addition, it was found that when the temperature in the storage box is low, the activity of ozone and chemical substances decreases, making it more difficult to decompose.

This embodiment was made in view of the above knowledge, and it aims at providing the food storage which can decompose chemical substances, such as an agricultural chemical, at the concentration of ozone which does not adversely affect a human body.

In order to achieve the above objects, the food storage of the present embodiment is provided with: a storage box forming a storage room for storing food; The door of the storage box, the first cooler for cooling the air in the first storage room, the second cooler for cooling the air in the freezing room and the second storage room, and blowing the cold air cooled by the second cooler to the refrigerator. room and the air supply unit of the second storage room, an ozone generating device that generates and supplies ozone into the second storage room, and radiation that can promote the ozone generated by the ozone generating device to food stored in the second storage room. A light source of light of a specified wavelength that decomposes chemical substances.

Accordingly, chemical substances such as agricultural chemicals can be efficiently decomposed by simultaneously irradiating light in a low-temperature environment with an ozone concentration applicable to food storage.

Moreover, you may provide the food container which is arrange|positioned inside the said 2nd storage room, and has the light transmissive part which introduces the light radiated from the said light source inside.

According to this, chemical substances such as pesticides remaining in food and the like can be decomposed by the combined action of light and ozone also on food stored in a food container in a storage room to maintain the freshness of food or the like.

The above-mentioned light sources are preferably respectively installed in a plurality of dispersed positions inside the second storage room.

According to this, it is possible to avoid occurrence of a shadow portion formed by the stored food as much as possible.

In this embodiment, chemical substances such as pesticides can be decomposed even at low temperature through the composite effect of ozone and light.

Next, embodiment of the food storage of this embodiment is demonstrated with reference to drawings. In addition, this embodiment is not limited to this embodiment.

FIG. 47 is a front view showing a food storage in Embodiment 8. FIG.

As shown in the figure, the food storage room 100 is a refrigerator provided with a storage box 170 and three doors 111, and the storage room formed inside the storage box 170 is divided into a refrigerator room 110 (in this embodiment, hereinafter, described as a first room). storage room 110 ), vegetable room 120 (in this embodiment, hereinafter, described as second storage room 120 ), and freezer room 130 .

In the same figure, the rectangular dotted line of the food storage room 100 indicates the openings of the first storage room 110, the second storage room 120, and the freezer room 130, and the object of storage, that is, food, is carried into the first storage room 110, which is divided into shelf shapes, from the front. In the second storage room 120 and the freezer room 130, it can also be taken out.

The function (cooling temperature) of the 1st storage room 110, the 2nd storage room 120, and the freezing room 130 differs according to the foods to store.

The first storage room 110 is a storage room set at a temperature such that stored items do not freeze for refrigerated storage. The lower limit of the specific temperature is usually set at 1 to 5°C.

The second storage room 120 is mainly intended for refrigeration of vegetables, and is a storage room kept at a low temperature such that storage items (vegetables) do not freeze, and is a so-called vegetable room. In addition, the temperature setting of the second storage room 120 is equal to or slightly higher than that of the first storage room 110 . The lower limit of the specific temperature is 2°C to 7°C. In addition, the lower the temperature, the longer the freshness of the leafy vegetables can be maintained.

Freezer room 130 is a storage room set in a freezing temperature zone. Specifically, it is usually set at -22 to -18°C for cryopreservation, but may be set at a low temperature of, for example, -30°C or -25°C in order to improve the state of cryopreservation.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 has a first door 111a that can open and close the first storage room 110, a second door 111b that can open and close the second storage room 120, and a third door 111c that can open and close the freezer compartment 130. The pages are attached to the storage box 170 in a switchable manner.

The heat insulating wall 115 (in this embodiment, hereinafter, described as the partition wall 115) is a plate-shaped member for partitioning the first storage room 110 and the second storage room 120, as shown in the figure, inside the storage box 170 It is integrally formed into a shelf shape. Moreover, the same partition wall 115 is provided also between the 2nd storage room 120 and the freezer room 130. As shown in FIG.

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse in FIG. 171 and the heat insulating material 173 between the outer case 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

The partition wall 115 has a structure in which a heat insulating material made of foamed resin is sandwiched between two thin plates made of the same resin as the inner box 171 .

Fig. 48 is a longitudinal sectional view showing the food storage.

As shown in the figure, the food storage 100 is equipped with the ozone generator 200, the isolation unit 210, and the light source 220. In addition, the food storage 100 is equipped with an upper container 123 (hereinafter referred to as the first container 123 in this embodiment) and a food container 121 (hereinafter referred to as the second container 123 in the present embodiment) inside the second storage room 120 . Two containers 121).

The ozone generator 200 is a device capable of generating ozone to be supplied to the first container 123 and the second container 121 arranged in the second storage room 120 , and to the inside of the other second storage room 120 . The ozone generator 200 is buried in the lower surface side of the partition wall 115 which partitions the 1st storage room 110 and the 2nd storage room 120 toward the inside of the 2nd storage room 120. As shown in FIG.

The ozone generator 200 includes a booster (not shown) that boosts a supplied power supply voltage, and an ozone generator (not shown) that generates ozone from oxygen in the air by arranging a high-potential terminal in space.

In addition, the ozone generator 200 is not limited to the above. Specifically, examples include a device for generating ozone (O ₃ ) by irradiating ultraviolet light to oxygen molecules (O ₂ ) in the air, and a device for supplying ozone into air by electrolysis of oxygen-containing substances such as water.

The isolation unit 210 is a part made of a thin plate that separates the ozone generating device 200 from the cold air ventilation passage 175 described later. As shown in FIG. A hood in the shape of a truncated pyramid. Isolation unit 210 is attached to the lower surface of partition wall 115 so as to cover ozone generator 200 embedded in partition wall 115 , and partitions ozone generator 200 from cool air passage 175 . In addition, the isolation unit 210 is provided with a plurality of suction holes 212 in front of the lower face.

The lower surface of the partition unit 210 is inclined so as to descend toward the rear position of the food storage 100, and the discharge hole 211 is arranged near the lowest position.

The cool air passage 175 means the main passage of cool air blown from the cooling chamber 114 by the blower unit 113 described later, and in the present embodiment, there is no member actively forming the cool air passage 175 such as a tunnel. Therefore, a part of the space in the second storage room 120 becomes the cold air ventilation path 175 .

Thereby, the cool air passing through the cool air ventilation passage 175 does not come into direct contact with the ozone generator 200 . Therefore, even if the flammable refrigerant leaks, it will not come into direct contact with the ozone generator 200 generating a high voltage, so the risk of explosion can be avoided.

In addition, since the ozone generator 200 is embedded in the partition wall 115 and is also covered with the partition unit 210, the temperature of the ozone generator 200 indirectly cooled by the cold air is in a state where the temperature hardly rises. Therefore, even in a state where cool air is not supplied to the second storage room 120, since the ozone generator 200 can be maintained at a low temperature, ozone can be efficiently generated.

Here, when the ozone generator 200 is in a low-temperature state, the electric loss of the ozone generator 200 decreases (due to a decrease in electrical resistance), so that ozone can be efficiently generated.

In addition, in this embodiment, the cold air ventilation passage 175 and the ozone generator 200 are separated by tangible components, but this embodiment need not be limited thereto, as long as the cold air ventilation passage 175 and the ozone generator 200 are separated, it is not necessarily necessary to physically separate the air passage 175 from the ozone generator 200. separate parts.

In addition, the isolation unit 210 can adjust the ozone concentration of the second storage chamber 120 according to the relationship between the ozone generation efficiency of the ozone generator 200, the amount of oxygen flowing into the isolation unit 210 through the suction hole 212, and the amount of ozone flowing out of the discharge hole 211. That is, the isolation unit 210 can adjust the first container 123 and the second container 121 inside, other The ozone concentration of the second storage room 120 as a whole. Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the first container 123 and the second container 121 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration in the first container 123 and the second container 121 up to the limit of the capacity of the ozone generator 200. On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in the first container 123 and the second container 121 decreases.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, based on a signal from the control board 132 , the movement and stop of the fan may be controlled. In addition, it is also possible to arrange the ozone concentration meter in such a manner that the ozone concentration in the second container 121 can be measured, and adjust (for example, ON and OFF of the above-mentioned fan) the operation of the ozone generator 200 based on information from the ozone concentration meter. The amount of ozone generated keeps the ozone concentration in the second container 121 within a predetermined range.

It is preferable to maintain the ozone concentration in the first container 123 and the second container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, pulling out the second container 121 and taking out foods such as vegetables from the second container 121 may have some influence on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

The light source 220 is a device that emits light of a predetermined wavelength that can promote decomposition of chemical substances such as pesticides by ozone on food stored in the second storage room 120 , which is a storage room. In the case of this embodiment, a light emitting diode (LED) is used as the light source 220 .

In addition, the light sources 220 are respectively installed in a plurality of dispersed positions inside the second storage room 120, and are arranged so as to minimize shadows of food stored in the second container 121 or the like. In addition, a part of the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

In this way, when light is activated while maintaining a predetermined ozone concentration, the effects of sterilization and mold prevention are more than that, for example, the decomposition of chemical substances such as agricultural chemicals can be carried out by ozone.

In addition, the wavelength emitted by the light source 220 is a predetermined wavelength that can promote the decomposition of pesticides by ozone on food stored in the storage room, and may be included in any wavelength region of the infrared region, visible region, and ultraviolet region.

Specifically, it is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide. The reason is that the pesticide is commonly used in food and has a high possibility of remaining in food. Wavelengths having effects on pesticides are considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target agrochemical, wavelengths corresponding to valleys of the spectrum, such as wavelengths of portions with strong absorption capabilities, are preferable. For example, preferred are wavelengths specified by the infrared absorption spectrum of chlorpyrifos, or malathion, or quinathion-based pesticides, and these wavelengths are prominent in infrared division.

On the other hand, it may be a wavelength activated by ozone. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if activated by ozone, it promotes the decomposition of pesticides.

In addition, irradiation of wavelengths in the ultraviolet region can also promote the decomposition of pesticides. This is a technique that promotes oxidation by combining extremely high-energy ultraviolet rays and ozone, which is an oxidizing agent, to generate hydroxyl radicals with stronger oxidizing power. By using the above technique, it is possible to use the ozone concentration lower than the ozone concentration at the time of the decomposition of the pesticide by ozone only, and thus realize safer decomposition of the pesticide.

In addition, the light emitting method of the light source 220 may be a method that easily decomposes pesticides. For example, consider a mode in which light source 220 is continuously turned on only when the ozone concentration in second storage room 120 is equal to or higher than a predetermined value. In consideration of the decomposition efficiency of the pesticide, the above-mentioned predetermined value is preferably 0.01 ppm or more. Alternatively, the light source 220 may be blinked at light emission intervals corresponding to multiples or submultiples of the natural frequency of the molecules constituting the pesticide. From this, it is considered that light energy can be more efficiently injected into the pesticide, and the pesticide can be easily decomposed by ozone.

In addition, in this embodiment, although a light emitting diode is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, as the light source 220, a plurality of light emitting diodes that emit lights of different wavelengths may be used in combination.

Moreover, the food storage 100 is equipped with the cooling unit 119, the ventilation unit 113, the damper 131 (in this embodiment, it describes below as the control valve 131), and the control board|substrate 132.

The cooling unit 119 is a device that discharges the heat in the storage room to the outside of the storage room through a cooling cycle. It is composed of a cooler, a radiator, a compressor, etc., and discharges the heat existing in one side to the other side through the evaporation and condensation of the refrigerant. refrigerant circuit configuration.

As shown in FIG. 48 , the cooling unit 119 includes two coolers, a first cooler 112a and a second cooler 112b.

Second cooler 112 b is attached to cooling room 114 provided on the back side of the inner surface of freezing room 130 , and cools the air introduced into freezing room 130 and second storage room 120 in cooling room 114 .

The first cooler 112 a is disposed on the back side of the first storage room 110 , and cools the first storage room 110 by directly exchanging heat with air in the first storage room 110 .

The blower unit 113 is a device for blowing the air cooled by the second cooler 112b to the freezer compartment 130 and the second storage compartment 120 . In the case of the present embodiment, an axial fan is used as the blower unit 113 .

The regulator valve 131 is a damper for adjusting the amount of cold air (air cooled by the second cooler 112b) blown by the blower unit 113 and discharged out of the second storage room 120, and can be adjusted by controlling the opening degree of the valve including full closing. to adjust.

The cold air cooled by the second cooler 112 b is cooled in the freezer compartment 130 and has a sufficiently low temperature, so that it cannot be continuously discharged into the second storage compartment 120 . Therefore, the discharge amount of the cold air to the second storage room 120 is adjusted by adjusting the valve 131, and the temperature of the second storage room 120 is maintained at a predetermined temperature (0° C. to 4° C.).

In addition, the second storage room 120 can also function as a freezing room if the set temperature is lowered and the regulator valve 131 is kept open for a long time.

The control board 132 is electrically connected to the cooling unit 119, the blower unit 113, the regulating valve 131, sensors (not shown), and is a board for controlling the above-mentioned devices.

As mentioned above, the cold air discharged into the second storage room 120 is cold air cooled to a level suitable for the freezer room 130, and therefore has a considerably low temperature. Therefore, the ozone generator 200 disposed near the discharge part of the cool air is sufficiently cooled without directly contacting the cool air. Moreover, the humidity of this cold air is also low. Therefore, since the ozone generator 200 can generate ozone efficiently, it can generate|occur|produce the necessary amount of ozone with low power consumption, and can contribute to energy saving.

Fig. 50 is a perspective view showing a first container, a second container and a cap.

The 1st container 123 is what is called a so-called fruit box arrange|positioned in the inner upper part of the 2nd storage room 120 which is a storage room. In the case of the present embodiment, the first container 123 is supported behind the upper part of the second container 121 described later in a stored state, and can be pulled out and pushed into the second storage room 120 together with the second container 121 . In addition, the first container 123 is provided with a plurality of outflow holes 128 through which ozone flows through in the thickness direction from the lower portion of the front wall, which is one of the peripheral walls, to the bottom.

In addition, the first container 123 is made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 . Therefore, the entire first container 123 becomes the light-transmitting portion 129 .

The second container 121 is disposed in the second storage room 120 which is a storage room, and is a food container that can be drawn and has an opening 127 that opens upward.

In addition, the second container 121 is made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 . Therefore, the entire second container 121 becomes the light-transmitting portion 129 .

Lid 122 , which is a constituent element of the food container, is a plate-shaped member that seals upper opening 127 of first container 123 and second container 121 , and includes passage hole 124 . The lid 122 has the function of adjusting the humidity in the first container 123 and the second container 121, specifically, it maintains the moisture emitted from the vegetables and fruits stored in the first container 123 and the second container 121 to a certain extent. In the first container 123 and the second container 121 , the humidity is adjusted at the same time to such an extent that the moisture does not condense in the first container 123 and the second container 121 .

The passage hole 124 is a plurality of through-shaped holes provided in the lid 122 and functions to adjust the state of the atmosphere (especially moisture) inside the first container 123 and the second container 121 . Specifically, the passage hole 124 also has the function of discharging the atmosphere inside the second container 121 and the like to the outside and introducing cold air and ozone outside the second container 121 into the inside of the second container 121 . Moreover, it also functions as the light transmission part 129 which transmits the light from the light source 220. FIG.

In addition, the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the lights radiated from the light source 220 , and the cover 122 as a whole functions as the light-transmitting portion 129 .

In addition, although the above-mentioned first container 123 , second container 121 , and cover 122 have been described as being entirely made of a light-transmitting material, the present embodiment is not limited thereto. For example, a light-transmitting member may be partially embedded to form the light-transmitting portion 129 , or a through hole may be formed to form the light-transmitting portion 129 .

According to the above structure, since the cold air of low temperature which cools the freezer compartment 130 is discharged to the vicinity of the ozone generator 200, the lifetime of ozone can be extended. Therefore, a sufficient amount of ozone can be distributed throughout the second storage room 120, and the sterilization and anti-mold effects can be achieved throughout the second storage room 120 (including the inside of the first container 123 and the second container 121).

In addition, since the second storage room 120 as a whole has a sufficient ozone concentration, chemical substances such as pesticides remaining in food can be decomposed by recombination with light from the light source 220 .

In addition, the cold air cooled by the second cooler 112b becomes cold air in a dry state because the second cooler 112b condenses and removes moisture. Therefore, even if ozone is mixed into the cool air, the ozone will not be decomposed into oxygen by moisture, and the high ozone concentration can be maintained continuously.

In addition, since the ozone generator 200 is indirectly cooled by the cold air, the efficiency of ozone generation is improved, and sufficient ozone can be generated even if the input energy is reduced.

In addition, since the second storage room 120 is configured such that the upper first storage room 110 and the lower freezer room 130 can be opened and closed independently by the second door 111b, the switching frequency of the second door 111b becomes smaller, and the second door 111b can be opened and closed. The appropriate ozone concentration is maintained in the second storage room 120, so the effect of removing pesticides can be improved.

This embodiment can be applied to a food storage, especially a refrigerator.

Signal.

About refrigerator 1100 comprised as mentioned above, the operation|movement and function are demonstrated below.

First, the operation of the refrigeration cycle will be described. According to the temperature set in the box, a refrigeration cycle is operated by a signal from a control board (not shown), and a cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor (not shown) is condensed and liquefied to some extent in the condenser (not shown), and is also passed through the side and back of the main body of the refrigerator and the refrigerator. The refrigerant piping (not shown) opened on the front surface of the main body condenses and liquefies while preventing dew condensation on the main body of the refrigerator, and finally reaches the capillary (not shown). Thereafter, in the capillary tube, the pressure is reduced while exchanging heat with the suction pipe (not shown) leading to the compressor, and becomes a low-temperature and low-pressure liquid refrigerant, which reaches the cooler 1105, and the evaporated low-temperature cold air is used by the fan 1106 The air passage and the damper 1110 divide the cold air into the refrigerator compartment 1102, the vegetable compartment 1103, and the freezer compartment 1104, and cool it down to the respective target temperature ranges.

The refrigerating room 1102 is cooled to a target temperature by using a damper 1110 to adjust the amount of cold air through a temperature sensor (not shown) provided in the refrigerating room 1102 . In particular, the vegetable compartment 1103 is adjusted to 2° C. to 7° C. by distributing cold air and ON/OFF operation of a heating device (not shown), and cools the cold air after cooling the refrigerator compartment 1102, and is configured to be used in the cooler. The refrigerating room of 1105 circulation returns to the outlet for the vegetable compartment 1103 in the middle of the air path, and is discharged into the vegetable compartment 1103 for cooling.

Next, in the operating state of the refrigerator 1100, by operating the ozone operation switch 1122 arranged on the front of the refrigerator door 1121, the ozone generating device 1200 arranged in the vegetable room 1103 generates ozone, and the vegetables and fruits are filled with ozone. Room 1103. The filled ozone is in contact with harmful substances such as pesticides attached to the surface of vegetables and fruits, and these harmful substances undergo a chemical reaction of oxidation and decomposition with ozone to decompose into harmless safe substances.

Here, the decomposition and removal of ozone generated by the ozone generator 1200 is like oxidative decomposition. When the concentration of ozone is as high as possible, it will enter into oxidative decomposition early. As a result, these harmful substances can be efficiently decomposed. However, when the concentration of ozone When the concentration is high, it will have adverse effects on the human body and may cause problems such as its odor turning into gas, so it is better to keep the concentration as low as possible. Therefore, in order to keep the vegetable compartment 1103 at an ozone concentration below 0.03ppm, which has no adverse effect on the human body and the ozone odor does not become a gas, the ozone generator 1200 repeats a cycle of running for 5 seconds and stopping for 5 seconds to The ozone concentration is controlled in such a way that the ozone concentration does not rise.

In addition, as described above, when cooling vegetable compartment 1103 , the cold air cooled by cooler 1105 is blown by fan 1106 through cooling air passage 1107 , through damper 1110 , and flows into vegetable compartment 1103 . Therefore, the ozone that fills the vegetable compartment 1103 is in an environment that easily diffuses from the vegetable compartment 1103 on board the cold air that is blown and flowed out during cooling. Therefore, in order to make the ozone concentration of the vegetable compartment 1103 uniform, the operation cycle of the ozone generator 1200 can be controlled according to the opening and closing of the damper 1110 .

Next, the discharge state is that the discharge voltage (the voltage at high voltage ON) Vb is output from the output detection unit 1203 as the discharge monitoring voltage of the high voltage generation circuit part 1202 (step 5), and the high voltage circuit determination unit of the control device 1210 is considered. For the abnormal discharge state of the discharge electrode 1206 and the counter electrode 1207 of the discharge part 1201, compare the discharge voltage Vb with the preset upper limit V4 and lower limit V3 (step 6), and if V3≤Vb≤V4 In this case, the discharge state of the discharge unit 1201 is judged to be normal. In addition, in order to determine the state of the discharge unit 1201 with the accuracy of adding the circuit fluctuation of the high voltage generating circuit unit 1202, the difference between the discharge voltage Vb and the reference voltage Va is compared with the preset value V5 set as the normal discharge region. (Step 7), when (Vb-Va)≦V5, discharge unit 1201 is judged to be normal.

In step 3, when V1>Va or Va>V2, the circuit of the high voltage generating circuit part 1202 is judged to be abnormal, does not output the high voltage to the ozone generator 1200, and outputs an abnormal signal (step 8).

In addition, in the case of V3>Vb or Vb>V4 in step 6, it is determined that the discharge part 1201 is abnormally caused by foreign matter adhesion or the circuit is abnormally caused by high voltage application, and the high voltage to the ozone generator 1200 is stopped ( Step 9), outputting an abnormal signal (step 8).

In addition, in the case of (Vb-Va)>V5 in step 7, the discharge unit 1201 is judged to be abnormal in the discharge unit due to the same foreign matter adhesion as described above, and the high voltage to the ozone generator 1200 is stopped (step 10), and the output is abnormal. signal (step 8).

Moreover, when the abnormality signal of step 8 is output, the display output of the abnormality warning of the ozone generator 1200 may be performed simultaneously.

In this way, in the present embodiment, by using the high-voltage circuit determination unit of the control unit 1212, the circuit abnormality of the high-voltage generating circuit unit 1202 that supplies a high voltage to the discharge unit 1201 from the signal of the discharge voltage detected by the output detection unit 1203 can be realized.

In Fig. 57, the refrigerator 1100 is powered on, and by the operation of the ozone operation switch 1122, the circuit voltage (DC14V) is supplied from the power supply circuit 1211 of the control device 1210 to the high voltage generating circuit part 1202 of the ozone generator 1200 (step 1) , the reference voltage (when the high voltage is OFF) Va is output from the output detection unit 1203 as the discharge monitoring voltage of the high voltage generating circuit section 1202 (step 2). Next, by using the high-voltage circuit determination unit of the control unit 1212, the reference voltage Va is compared with the preset upper limit value V2 and lower limit value V1 in consideration of the circuit fluctuation of the high-voltage generating circuit unit 1202 (step 3), In the case of V1≤Va≤V2, the circuit of the high voltage generating circuit part 1202 is judged to be normal, the output of the high voltage generating signal is performed, and a high voltage is applied from the high voltage generating circuit part 1202 to the discharge part 1201 (step 4), Thus, the discharge through the discharge electrode 1206 and the counter electrode 1207 is discharged into the vegetable compartment 1103 as ozone.

Next, the discharge state is that the discharge voltage (the voltage at high voltage ON) Vb is output from the output detection unit 1203 as the discharge monitoring voltage of the high voltage generation circuit part 1202 (step 5), and the high voltage circuit determination unit of the control unit 1212 is considered. For the abnormal discharge state of the discharge electrode 1206 and the counter electrode 1207 of the discharge part 1201, compare the discharge voltage Vb with the preset upper limit V4 and lower limit V3 (step 6), and if V3≤Vb≤V4 In this case, the discharge state of the discharge unit 1201 is judged to be normal. In addition, in order to determine the state of the discharge unit 1201 with the accuracy of adding the circuit fluctuation of the high voltage generating circuit unit 1202, the difference between the discharge voltage Vb and the reference voltage Va is compared with the preset value V5 set as the normal discharge region. (Step 7), when (Vb-Va)≦V5, discharge unit 1201 is judged to be normal.

In step 3, when V1>Va or Va>V2, the circuit of the high voltage generating circuit part 1202 is judged to be abnormal, does not output the high voltage to the ozone generator 1200, and outputs an abnormal signal (step 8).

In addition, in the case of V3>Vb or Vb>V4 in step 6, it is determined that the discharge part 1201 is abnormally caused by foreign matter adhesion or the circuit is abnormally caused by high voltage application, and the high voltage to the ozone generator 1200 is stopped ( Step 9), use the abnormal signal counter to count the number of times Ca of abnormal signals (step 10). Next, the number counted by the abnormal signal counter is compared with the preset count C100 (step 11), and when Ca≥C100, an abnormal signal is output (step 8). In the case of Ca<C100 in step 11, the process proceeds to step 4 after waiting for a predetermined time.

In addition, in the case of (Vb-Va)>V5 in step 7, the discharge unit 1201 is judged to be abnormal in the discharge unit due to the same foreign matter adhesion as described above, and the high voltage to the ozone generator 1200 is stopped (step 12), and the abnormality is used. The signal counter counts the times Cb of abnormal signals (step 13).

Next, the number counted by the abnormal signal counter is compared with the preset count C100 (step 14), and when Cb≧C100, an abnormal signal is output (step 8). In the case of Cb<C100 in step 14, the process proceeds to step 4 after waiting for a predetermined time.

In addition, in the case of Ca<C100 in step 11 and the case of Cb<C100 in step 14, after waiting for a predetermined period of time, the process proceeds to step 4, but the damper 1110 may be operated by the cold airflow of the vegetable compartment 1103. signal, make the transition to step 4.

Moreover, when the abnormality signal of step 8 is output, the display output of the abnormality warning of the ozone generator 1200 may be performed simultaneously.

In addition, in step 11 and step 14, Ca and Cb were respectively compared with the preset statistical number C100, but the total statistical number of Ca and Cb may be compared with C100 in each step.

In this way, in the present embodiment, by using the high-voltage circuit determination unit of the control unit 1212, the circuit abnormality of the high-voltage generating circuit unit 1202 that supplies a high voltage to the discharge unit 1201 from the signal of the discharge voltage detected by the output detection unit 1203 can be realized. Judgment of abnormal discharge caused by dew condensation on the electrodes of the discharge part 1201 and adhesion of foreign matter, etc., especially, the abnormal discharge of the discharge part 1201 is related to the discharge with many uncertain factors such as moisture and foreign matter adhesion to the electrode part, and the abnormality is counted If the number of times is less than the preset number of times, the operation of the ozone generator 1200 will be performed through automatic recovery of the discharge. The high voltage of the circuit part 1202 does not conduct wasteful energization, so it is possible to improve safety and reduce power consumption.

As described above, when the refrigerator of this embodiment is implemented in a household or commercial refrigerator or a vegetable-only box, of course, it can also be applied to low-temperature distribution of foods such as vegetables, storage, and the like.

(Embodiment 10)

The present embodiment relates to a food storage including a refrigerator, and particularly relates to a food storage including an air blower that circulates air in the storage room and prevents air stagnation in the storage room.

Currently, ozone having a strong oxidizing effect is used for sterilization and mold prevention in refrigerators and the like. For example, (Japanese) Patent Document 2: The indirect cooling type refrigerator described in Japanese Unexamined Publication No. 2001-91146 is provided with a cooler and an air supply unit in a room different from the storage room, and the air cooled by the cooler is blown by the air supply unit. To the storage room, to cool the storage room. Therefore, the air in the storage room flows forcibly, and ozone is generated in the air flow, so that bacteria are sterilized and antibacterial throughout the entire storage room.

However, when ozone is generated in the state of air flow in the storage room, it is considered that the effect of sterilization and antibacterial degree can be generally obtained, but it is found that it is difficult to obtain the effect above that, such as decomposing chemical substances such as pesticides.

This embodiment is an embodiment based on the results of the above studies, and an object thereof is to provide a food storage that can achieve the effects of sterilization and antibacterial effects using ozone.

In order to achieve the above object, the food storage of this embodiment is characterized by comprising: a storage box forming a storage room for storing food, a door for opening and closing the storage box, a cooling unit for cooling the air in the storage room, and making the storage room in the storage room A blower unit for air circulation, an ozone generator for generating ozone to be supplied to the storage room, and a control device for obtaining whether air in the storage room is flowing and controlling so as not to supply ozone to the storage room when the air is flowing.

Accordingly, the ozone generator can generate ozone without the air in the storage room flowing, so that high-concentration ozone can efficiently act on the stored food or its vicinity. In addition, when the air in the storage room is flowing, the ozone generator does not generate ozone, so wasteful energy is not consumed, which contributes to energy saving.

In addition, the cooling unit and the blower unit are housed in a cooling room different from the storage room, and further include a control valve for controlling the flow rate of air flowing from the cooling room to the storage room, and the control device is preferably based on whether the control valve is opened. Whether the state is still in the closed state, whether the air in the above-mentioned storage room is flowing is obtained and controlled.

Thereby, whether or not the air in the storage room is flowing can be easily obtained, and ozone can be reliably generated only when the air in the storage room is not flowing.

It is preferable that the control device controls so as to supply ozone to the storage room when the air blower is in a stopped state even if the control valve is in an open state.

According to this, even when the regulator valve is in the open state, it is possible to obtain the situation where the air in the storage room does not flow, and ozone can be generated in many cases.

In addition, the control device may acquire whether the air in the storage compartment is flowing based on whether the air blower is in a movable state or in a stopped state.

Thereby, whether or not the air in the storage room is flowing can be easily obtained, and ozone can be reliably generated only when the air in the storage room is not flowing.

In addition, the food storage is characterized by comprising: a storage box forming a storage room for storing food, a door for opening and closing the storage box, a cooling unit for cooling the air in the storage room, a blower unit for flowing the air in the storage room, An ozone generator for generating ozone supplied to the storage room, and a control device for controlling an output of the ozone generator are operated by varying the output of the ozone generator when the blower unit is ON and OFF.

Thereby, the ozone density|concentration in a store room can be maintained stably.

In this embodiment, the ozone generated by the ozone generating device can efficiently act on the food stored in the storage room and its vicinity.

Next, embodiment of the food storage of this embodiment is demonstrated with reference to drawings. In addition, this embodiment is not limited to this embodiment.

(Embodiment 10-1)

Fig. 59 is a front view showing the food storage in Embodiment 10-1.

As shown in the figure, the food storage 100 is a refrigerator provided with three doors 111, and the storage room formed by the storage box 170 is divided into three.

The food storage 100 is provided with the refrigerator compartment 110, the vegetable compartment 120, and the freezer compartment 130 as the storage compartment divided from the upper part. In the same figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried into and out of the shelf-shaped storage box 170 from the front.

Moreover, the food storage 100 is equipped with the door 111 which can seal the storage box 170 and which can open and close. Specifically, the food storage room 100 includes a first door 111a that can open and close the refrigerator compartment 110, a second door 111b that can open and close the vegetable compartment 120, and a third door 111c that can open and close the freezer compartment 130. The door 111 can be opened and closed by a hinge. Installed in the storage box 170 .

The storage box 170 has the function of insulating the outside and the inside. As shown in the ellipse of the figure, the inner box 171 vacuum-formed with resin such as ABS, and the outer box 172 using metal materials such as pre-coated steel plates are arranged between the inner box 171 and the outer box 172. The heat insulating material 173 between the outer boxes 172 constitutes. In addition, the door 111 is also composed of an inner panel, an outer panel, and a heat insulating material 173 in the same manner.

Fig. 60 is a longitudinal sectional view of food storage 100 according to this embodiment.

As shown in the figure, the food storage 100 is equipped with the ozone generator 200, the isolation unit 210, and the light source 220. In addition, the food storage 100 includes an upper container 123 (hereinafter referred to as the first container 123 in this embodiment) and a food container 121 (hereinafter referred to as the second container 121 in the present embodiment) inside the vegetable compartment 120 . , and cover 122.

The ozone generator 200 is a device capable of generating ozone supplied to the first container 123 and the second container 121 arranged in the storage room. Ozone generator 200 is embedded on the lower surface of heat insulating wall 115 (hereinafter referred to as shelf 115 in this embodiment) that partitions refrigerator compartment 110 from vegetable compartment 120 toward the inside of vegetable compartment 120 . Therefore, the ozone generator 200 is disposed above the opening 127 of the second container 121 described later, at a position away from the opening 127 of the second container 121 , and at a position facing the opening 127 .

In addition, the ozone generator 200 can generate or stop ozone based on a signal from the control board 132 described later.

Thus, by embedding the ozone generator in the shelf 115, the temperature of the ozone generator 200 is hardly changed due to the temperature change of the vegetable compartment 120, and the ozone generation efficiency can be maintained stably.

In addition, ozone can be generated as needed.

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specifically, examples include: a device that irradiates ultraviolet light to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ); A device that converts into ozone, a device that electrolyzes oxygen-containing substances such as water, and supplies ozone into the air, etc.

The isolation unit 210 is a part made of a thin plate that separates the ozone generating device 200 from the storage room. As shown in FIG. . The isolation unit 210 is attached to the lower surface of the shelf 115 so as to cover the ozone generator 200 embedded in the shelf 115 , and isolates the ozone generator 200 from the vegetable compartment 120 . In addition, the isolation unit 210 is provided with a plurality of suction holes 212 in front of the lower face.

The lower surface of the partition unit 210 is inclined so as to descend toward the rear position of the food storage 100, and the discharge hole 211 is arranged near the lowest position.

Accordingly, ozone having a specific gravity heavier than air is mainly discharged downward from the discharge hole 211 . On the other hand, the suction hole 212 disposed in the front mainly functions as a hole for sucking in the atmosphere outside the isolation unit 210 . In the case of the present embodiment, the suction hole 212 sucks the cool air discharged from the cool air discharge port 213 described later and passes along the outer wall of the second container 121 .

In addition, the isolation unit 210 can adjust the ozone concentration of the vegetable compartment 120 according to the relationship between the ozone generation efficiency of the ozone generator 200, the amount of oxygen flowing into the isolation unit 210 through the suction hole 212, and the amount of ozone flowing out of the discharge hole 211. That is, the isolation unit 210 can adjust the ozone concentration of the first container 123 and the second container 121 to a certain extent by determining the total opening area of the discharge hole 211 and the total opening area of the suction hole 212 arranged in the isolation unit 210 at the design stage. . Specifically, when there are many discharge holes 211 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the first container 123 and the second container 121 increases. In addition, since the inflow of oxygen increases in proportion to the outflow of ozone, the number of discharge holes 211 is proportional to the ozone concentration in the first container 123 and the second container 121 up to the limit of the capacity of the ozone generator 200. On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone decreases, and the ozone concentration in the first container 123 and the second container 121 decreases.

In addition, although the above-mentioned isolation unit 210 flows out ozone and flows in oxygen by natural convection, it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, based on a signal from the control board 132, the movement or stop of the fan may be controlled. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the second container 121, and adjust (for example, ON and OFF of the above-mentioned fan) the ozone concentration of the ozone generator 200 based on the information from the ozone concentration meter. The generated amount keeps the ozone concentration in the second container 121 within a predetermined range.

It is preferable to maintain the ozone concentration in the first container 123 and the second container 121 which are food storage rooms at 0.05 ppm or less. The reason is that when the ozone concentration is higher than this, when pulling out the second container 121 and taking out food such as vegetables from containers such as the second container 121, some effects may be brought on the human body of the user who performs these operations. . In addition, it is preferably maintained at 0.03 ppm or less. The reason is that when the ozone concentration is higher than this, people who perform the above-mentioned work may feel uncomfortable due to ozone odor.

The light source 220 is a device that emits light of a predetermined wavelength that can promote the decomposition of pesticides by ozone for food stored in the vegetable compartment 120 that is a storage compartment. In the case of this embodiment, a light emitting diode (LED) is used as the light source 220 .

In addition, the light source 220 is disposed inside the isolation unit 210 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the light source 220, thereby reducing the decomposition efficiency of pesticides.

Therefore, at least the isolation unit 210 is preferably made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

In addition, the wavelength emitted by the light source 220 is a predetermined wavelength that can promote the decomposition of pesticides by ozone on food stored in the storage room, and may be included in any wavelength region of the infrared region, visible region, and ultraviolet region.

Specifically, it is preferably a wavelength that resonates with the vibration of molecules constituting the pesticide, and this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, wavelengths corresponding to valleys of the spectrum, such as the wavelength of the portion with the strongest absorption capability, are preferable. For example, a wavelength specified by the infrared absorption spectrum of chlorpyrifos, or malathion, or quinathion-type pesticides is preferable. The reason is that these pesticides are commonly used in foods and have a high possibility of remaining in foods.

On the other hand, it may be a wavelength activated by ozone. For example, ozone absorbs wavelengths in the infrared region. The reason is that, if activated by ozone, it promotes the decomposition of pesticides.

In addition, the light emitting method of the light source 220 may be a method that easily decomposes pesticides. For example, consider a method of continuously lighting light source 220 only when the ozone concentration of vegetable compartment 120 is equal to or higher than a predetermined value. In consideration of the decomposition efficiency of the pesticide, the above-mentioned predetermined value is preferably 0.01 ppm or more. Alternatively, the light source 220 may be blinked at light emission intervals corresponding to multiples or submultiples of the natural frequency of the molecules constituting the pesticide. From this, it is considered that light energy can be more efficiently injected into the pesticide, and the pesticide can be easily decomposed by ozone.

In addition, in this embodiment, although a light emitting diode is used as the light source 220, it is not limited to this in particular, The light source 220 which emits the light of a continuous spectrum may be sufficient. In addition, as the light source 220, a plurality of light emitting diodes that emit lights of different wavelengths may be used in combination.

Moreover, the food storage 100 is equipped with the cooling unit 119, the ventilation unit 113, the damper 131 (in this embodiment, it describes below as the control valve 131 or the damper apparatus 131), and the control board|substrate 132.

The cooling unit 119 is a device that discharges heat in the storage room to the outside of the storage room through a cooling cycle, and is composed of a refrigerant circuit composed of a cooler 112, a radiator, a compressor, and the like.

In the case of the present embodiment, the cooling unit 119 includes two coolers 112 , a first cooler 112 and a second cooler 139 .

First cooler 112 is attached to cooling room 114 , which is another room provided on the back side of the inner surface of freezing room 130 , and cools the air introduced into the storage room of cooling room 114 .

The second cooler 112 is disposed on the back side of the refrigerating room 110 , and cools the refrigerating room 110 by directly exchanging heat with the air in the refrigerating room 110 .

The blower unit 113 is a device for blowing the air cooled by the first cooler 112 to the freezer compartment 130 and the vegetable compartment 120 . In the case of the present embodiment, an axial fan is used as the blower unit 113 .

Regulating valve 131 is a damper for adjusting the amount of cool air (air cooled by cooler 112 ) blown from air blowing unit 113 and discharged out of vegetable compartment 120 , and can be adjusted by controlling the opening of the valve including fully closed.

The cold air cooled by first cooler 112 is cooled in freezer compartment 130 to a sufficiently low temperature, and thus cannot be continuously discharged into vegetable compartment 120 . Therefore, by adjusting the valve 131, the discharge amount of the cold air to the vegetable compartment 120 is adjusted, and the temperature of the vegetable compartment 120 is maintained at a predetermined temperature (0° C. to 4° C.).

The control board 132 is electrically connected to the cooling unit 119, the blower unit 113, the regulating valve 131, sensors (not shown), etc., is a board for controlling the above-mentioned devices, and includes a control unit 133 and the like as a control device.

Fig. 62 is a block diagram showing the control system of the food storage,

As shown in the figure, the control unit 133 is connected to the regulating valve 131, the blower unit 113, the cooling unit 119, the ozone generator 200, the light source 220, and various sensors, and is a processing unit that controls the connected devices according to a prescribed program. For example, the following processing is performed by the control unit 133 .

(Control 1)

The temperatures of refrigerator compartment 110, vegetable compartment 120, and freezer compartment 130 are measured by various sensors, and control unit 133 acquires the information. Based on this information, cooling unit 119 and air blowing unit 113 are ON OFF controlled so that each storage room reaches the set temperature, and the valve opening degree of regulator valve 131 is controlled.

(Control 2)

The control unit 133 acquires information indicating that the regulator valve 131 is fully closed, determines that the air in the vegetable compartment 120 is not flowing, and controls the ozone generator 200 so as not to supply ozone to the storage compartment. Specifically, what is necessary is just to control so that ozone may not generate|occur|produce shutting off the electric power supplied to the ozone generator 200. In addition, when the supply of ozone to the storage room is performed with the ON/OFF of the opening and the fan, the control to close the opening and the control to turn off the fan may be performed so that the ozone is not supplied to the vegetable compartment 120. ozone.

The information indicating that the regulator valve 131 is fully closed may be obtained directly from the valve state of the regulator valve 131 , or may be obtained based on control information when the regulator valve 131 is fully closed.

Alternatively, the light source 22 may be turned on only when ozone is generated.

(Control 3)

In addition, the regulating valve 131 is not fully closed, and the control unit 133 may also determine that the air in the vegetable compartment 120 is not flowing when the control unit 133 obtains information indicating that the air blowing unit 113 is stopped, so that ozone is not supplied to the storage compartment. Take control.

Fig. 63 is a perspective view showing a first container, a second container and a cap.

The first container 123 is a box arranged in the upper part of the vegetable room 120 which is a storage room, that is, a position where ozone discharged from the ozone generator 200 is received, and is a container called a so-called fruit box. In the case of the present embodiment, the first container 123 is supported behind the upper part of the second container 121 described later in a stored state, and can be pulled out and pushed into the vegetable compartment 120 together with the second container 121 . In addition, the first container 123 is provided with a plurality of outflow holes 128 through which ozone flows through in the thickness direction from the lower portion of the front wall, which is one of the peripheral walls, to the bottom. In addition, the first container 123 is made of a material that can sufficiently transmit light of a necessary wavelength among the light emitted from the light source 220 .

The second container 121 is disposed in the vegetable compartment 120 which is a storage room, and is a drawable box having an opening 127 opening upward.

The lid 122 is a plate-shaped member that seals the upper openings 127 of the first container 123 and the second container 121 , and includes a passage hole 124 and an adjustment hole 125 . In addition, the cover 122 is made of a material that can sufficiently transmit light of a necessary wavelength among the light radiated from the light source 220 . The lid 122 has the function of adjusting the humidity in the first container 123 and the second container 121, specifically, it maintains the moisture emitted from the vegetables and fruits stored in the first container 123 and the second container 121 to a certain extent. In the first container 123 and the second container 121 , the humidity is adjusted at the same time to such an extent that the moisture does not condense in the first container 123 and the second container 121 .

The passage hole 124 is mainly a hole having a function of passing ozone, and is a hole penetrating through the cover 122 in the thickness direction. In addition, as shown in FIG. 64A , the passing hole 124 has a conical shape whose diameter gradually expands upward. In addition, since the passage hole 124 is the hole that introduces the ozone generated by the ozone generating device 200 into the first container 123, it is therefore arranged directly below the discharge hole 211 provided on the isolation unit 210 and the area around it (the discharge hole corresponds to the position 126 (Refer to FIG. 63)).

By forming the passage hole 124 in such a shape, the part of the passage hole 124 with a large diameter catches the ozone falling from the discharge hole 211 of the isolation unit 210 , and the ozone can be efficiently introduced into the first container 123 . On the other hand, the moisture existing in the first container 123 and the second container 121 can be consistent with the outflow of the adjustment hole 125 described later, and the humidity inside the second container 121 can be adjusted according to the design concept.

The adjustment hole 125 is a through-shaped hole provided in a portion other than the discharge hole corresponding position 126, and is provided to adjust the state of the atmosphere (especially moisture) inside the first container 123 and the second container 121 to adjust the internal atmosphere. Part of the function that exhausts air to the outside. As shown in FIG. 64B , the adjustment hole 125 is a hole penetrating through the cover 122 in the thickness direction. In addition, the number and size of the adjustment holes 125 are determined in the design stage according to the range to be adjusted (eg, the range of humidity in the second container 121 ).

If it is made as the structure of the above-mentioned container, the ozone discharged from the ozone generating device 200 is introduced into the first container 123 first, and then is exported to the second container 123 from the outflow hole 128 provided on the lower part and bottom of the peripheral wall of the first container 123. Container 121. Therefore, the ozone is not only stored in the first container 123 , but the ozone can be distributed to the second container 121 as a whole.

Moreover, by providing the outflow hole 128 at the corner connecting the peripheral wall and the bottom of the first container 123 , it is possible to efficiently flow ozone to the second container 121 below. In addition, it is assumed that the food stored in the first container 123 is fruit. Fruit is spherical mostly, if outflow hole 128 is set at the corner of first container 123, then can avoid that outflow hole 128 is blocked because of food.

As mentioned above, when the air in the vegetable compartment 120 does not flow, ozone is supplied to the first container 123 and the second container 121 located in the vegetable compartment 120, so the ozone of a predetermined concentration will stagnate in the first container 123 and the second container. 121. Therefore, it is possible to secure a concentration necessary for decomposing chemical substances remaining in foods such as vegetables and fruits stored in the first container 123 and the second container 121 , especially pesticides.

In addition, if the air flow in the vegetable compartment 120 is controlled so that ozone is generated, the energy necessary for ozone generation can be saved, which contributes to energy saving.

In addition, in this Embodiment, although the indirect cooling type refrigerator (vegetable compartment 120, freezer compartment 130) was illustrated and demonstrated, this invention is not limited to this.

For example, it may be a direct cooling type refrigerator (refrigerator room 110), and the air blower unit 113 may be provided in the storage room in order to force the air in the storage room to flow. In this case, what is necessary is just to control the ozone generator 200 based on ONOFF of the blower unit 113.

(Embodiment 10-2)

Fig. 65 is a diagram showing the operation of the ozone generator according to Embodiment 10-2. About the structure of a refrigerator, it is the same as Embodiment 10-1, and the description is abbreviate|omitted.

As shown in the figure, the blower unit 113 is driven in the ON state, and in the state of cooling the freezer compartment 130 and the state of not cooling the vegetable compartment 120, that is, when the regulating valve 131 is the closed state of the damper device, power is supplied to the ozone generator 200 to The manner in which the generated ozone flows into the second container 121 of the vegetable compartment 120 is controlled.

Then, the freezer compartment 130 is cooled to a predetermined temperature, the blower unit 113 is turned off and stopped, and when the damper device 131 is closed, the ozone generator 200 lowers the output to be lower than the output when the blower unit 113 is ON. , becomes the control of the inflow of ozone into the second container 121 .

This is because even if the damper device 131 is in a closed state and the cold air discharge air path leading to the vegetable compartment 120 is in a closed state, the cold air return air path (not shown) formed in the vegetable compartment 120 is also in an open state, so the vegetable compartment 120 The air inside is in a convective state, so the ozone concentration is difficult to stabilize,

Therefore, even if the damper device 131 is closed, the output of the ozone generator 200 can be changed by turning on and off the blower unit 113 to stabilize the ozone concentration in the second container 121 .

Specifically, the output of the ozone generator 200 at the time of the air blower OFF is lower than the output of the ozone generator 200 at the time of the air blower ON, and it operates.

In the above case, when the damper device 131 is in a closed state, stop the ozone generating device 200, but when the damper device 131 is in an open state, further increase the output of the ozone generating device 200 to generate ozone, which can increase the amount of ozone generated in the vegetable compartment. The ozone circulating in 120 prevents and stabilizes the ozone concentration in the second container 121 from decreasing.

This embodiment is applicable to a food storage in which the air inside may flow, especially a storage box or a refrigerator for storing food containing chemical substances such as pesticide residues.
