Description

Food storage and cold storage

technical field

The present invention relates to a food storage and a refrigerator.

Background technique

In recent years, consumers' anxiety about food safety has increased, especially about pesticide residues in food. According to the results of the (Japanese) National Awareness Survey, about 90% of consumers feel uneasy.

In order to ensure the safety of residual pesticides, the Food Sanitation Act and the system of laws and regulations, which regulate the use of pesticides by farmers and regulate the amount of pesticide residues from the perspective of human health, have been promulgated. However, in fact, in the inspection of residual pesticides carried out by the Japanese Ministry of Health, Labor and Welfare every year, so-called violations of agricultural products exceeding the prescribed amount and residual pesticides are detected. Pesticide residues with a high detection rate are mainly pesticides used overseas for post-harvest treatment, and there are also a large number of pesticides that are banned in Japan. In the implementation of such residual pesticides, there is a high need for a device for removing residual pesticides in order for consumers to eat with peace of mind.

Conventionally, there is a refrigerator provided with an ozone generator (for example, refer to Patent Document 1). FIG. 47 is a schematic configuration diagram of a conventional refrigerator including an ozone generator described in Patent Document 1. FIG.

As shown in the figure, a conventional refrigerator provided with an ozone generator consists of a refrigerator main body 1, a refrigerator compartment 3, a vegetable refrigerator compartment 4, a switching compartment 5, a freezer compartment 6, a hinged refrigerator door 7, and a drawer. Type vegetable compartment door 8, switch compartment door 9, freezer compartment door 10 constitute. A deodorizing and antibacterial device (corresponding to an antibacterial means, an ozone generator) 18 is provided on the cold air inlet path of the switch chamber 5, and an ozone treatment device 19 is arranged on the cold air outlet path.

In addition, by selecting the set temperature zone of the switching chamber 5, the user can set an appropriate set temperature from freezing, partial, low-temperature refrigeration, vegetable, high-temperature vegetable, soft freezing, refrigeration, and alcohol mode.

FIG. 48 is a schematic configuration diagram of an operation panel of a conventional refrigerator including an ozone generator described in Patent Document 1. FIG.

As shown in FIG. 48 , the operation panel is provided with a switch 57 for switching the setting mode of the switching chamber 5 and a display panel 55 for displaying the mode in which the switching chamber 5 is selected.

The operation of the refrigerator configured as above will be described below.

When accommodating low temperature sensitive fruits such as bananas, eggplants, cucumbers, etc. that easily cause discoloration, softening, edema, etc. when cooling, the mode of the switching chamber 5 is selected as "high temperature vegetables", and the mode of the switching chamber 5 is changed. The switching chamber 5 whose mode is changed to "high-temperature vegetables" drives the deodorizing and antibacterial device 18 provided on the cold air inflow path while cooling to a temperature of 10° C. to 15° C. to generate ozone. Then, the cold air flowing into the switching chamber 5 is subjected to antibacterial treatment, and the ozone treatment device 19 arranged on the outlet path of the cold air is driven to decompose and treat the ozone, so as to make the ozone harmful to the human body harmless.

In addition, since the ozone generated at this time is supplied to the switching chamber 5 in a state contained in the cool air, the switching chamber 5 is filled with ozone. Therefore, it is possible to prevent growth of fungi such as air in the switching chamber 5 and mold on the surface of vegetables. As a result, the freshness of the low-temperature-sensitive fruit stored at a relatively high refrigeration temperature can be maintained.

On the other hand, the ozone generation amount of the deodorizing antibacterial device 18 is set so that the ozone concentration in the switch chamber 5 is 0.005 ppm or less. Therefore, there is no influence on the user who opens the switching chamber door 9, and the odor of ozone will not be felt either.

In the above-mentioned conventional structure, the deodorization of the switch chamber 5 and the prevention of the deodorization of the surface of the vegetables stored at the set temperature of 10° C. to 15° C. The reproduction of fungi such as mold. However, at low concentrations of ozone below 0.005 ppm, there is a problem that the generated ozone concentration is low for effectively reducing harmful substances such as pesticides adhering to vegetables, fruits, and the like.

In addition, the ozone treatment device 19 is arranged on the cold air outflow path. Since the generated ozone moves only by the flow of cold air, there is a problem that it is difficult to diffuse throughout the storage room, and the effect cannot be spread over the entire food in the storage room.

In addition, regarding the adjustment of the amount of ozone generation, there is also a problem that a new control device and detection means need to be installed, and the structure is complicated.

In addition, there is such a problem that the deodorizing and antibacterial device 18 is not provided on the air passage for cooling storage rooms in the freezing temperature range such as refrigerators and vegetable rooms where fungi can grow due to storage in a relatively high temperature range.

In addition, in the above-mentioned conventional structure, the purpose of the ozone processing device 19 is to deodorize and antibacterially perform the cool air flowing into the refrigerator compartment. Therefore, the ozone generator is operated when cold air flows in, and ozone treatment is performed when cold air flows out. Therefore, the generation of ozone in a state where cool air does not flow is not considered.

In addition, since the ozone treatment device 19 is located on the cold air outflow side, even if the inside of the storage room is filled with high-concentration ozone, the ozone in the storage room becomes high-concentration due to an abnormality of the ozone generator or the like because the ozonolysis is performed on the outflow side. Possibility of ozone.

In addition, in the above-mentioned conventional structure, it is not taken into account that ozone actively decomposes harmful substances such as agricultural chemicals. There is a problem that after the ozone is decomposed, post-decomposition substances which are less harmful than those before the decomposition are produced but still need to be removed as much as possible.

In addition, the user knows by notifying the mode change to "high-temperature vegetables" from the display panel 55 . However, since the preserved food is difficult to produce effects such as discoloration, softening, and water rot, and the efficacy is not directly reported to consumers, there is a problem that users cannot freely use the rarely equipped functions that are difficult to produce discoloration and water rot.

detailed description

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

(Embodiment 1)

Fig. 1 is a front view of a food storage in Embodiment 1 of the present invention.

As shown in this 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 from the upper part as a divided store room. In this figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried in and out from the front into the storage box 170 partitioned in a shed shape. The refrigerator compartment 110 and the vegetable compartment 120 , and the vegetable compartment 120 and the freezer compartment 130 are respectively separated by a shelf board 115 .

Moreover, the food storage 100 is provided with the door 111a, 111b, 111c which can airtightly open and close the storage box 170. As shown in FIG. Specifically, food storage 100 has door 111 a which can open and close refrigerator compartment 110 , door 111 b which can open and close vegetable compartment 120 , and door 111 c which can open and close freezer compartment 130 . Doors 111a, 111b, and 111c are attached to storage box 170 so as to be openable and closable by bolts.

The storage box 170 has the function of insulating the outer side from the inner side. As shown in the ellipse in the figure, the storage box 170 is vacuum-formed by an inner box 171 made of resin such as acrylonitrile-butadiene-propylene-styrene copolymer (Acrylonitrile Butadiene Styrene: ABS), The outer case 172 made of metal materials such as pre-coated steel plates and the heat insulating material 173 arranged between the inner case 171 and the outer case 172 are constituted. In addition, the doors 111a, 111b, and 111c are also composed of an inner panel, an outer handle, and a heat insulating material 173 in the same manner.

Fig. 2 is a longitudinal sectional view of the food storage according to Embodiment 1 of the present invention.

As shown in this figure, the food storage 100 has the ozone generator 200, the 1st partition device 210, and the 1st light source 220 which is an activation device. Moreover, the food storage 100 is provided with the storage container 121 and the cover 122 inside the vegetable compartment 120 . Moreover, the upper container 123 which is a food container is also provided in the rear part in the storage container 121. As shown in FIG. The storage container 121 has a large and deep capacity, and is suitable for storing relatively large fruits and vegetables such as spinach and other leafy vegetables or root vegetables such as radishes without damage. In addition, the upper container 123 has a small capacity and is generally called a fruit box, which is suitable for storing apples, grapes, etc. Grapefruit and other fruits.

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

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

Here, the ozone generator 200 is not particularly limited as long as it generates ozone. Specific examples include a device that irradiates oxygen molecules (O ₂ ) in the air with ultraviolet rays to generate ozone (O ₃ ), or that converts oxygen molecules in the air into ozone by a discharge or the like by setting an electrode placed in the air at a high voltage. devices, devices that electrolyze oxygen-containing substances such as water, and devices that supply ozone to the air, etc.

Fig. 3 is a front view of a first partition device of the food storage according to Embodiment 1 of the present invention. The first partition device 210 is a part made of a thin plate separating the ozone generator 200 and the storage room. As shown in FIG. The first partition device 210 covers the ozone generator 200 embedded in the heat insulating wall, and is installed on the lower surface of the shelf 115 made of the heat insulating wall, thereby separating the ozone generating device 200 and the vegetable compartment 120 .

In addition, the first partition device 210 is provided with a suction hole 212 behind the lower surface. The suction hole 212 disposed at the rear mainly functions to suck the gas outside the first partition device 210 . In the case of the present embodiment, since the cover suction hole 212 is located in the vicinity of a cool air discharge port 213 (see FIG. 2 ), which will be described later, cool air in a relatively dry state is sucked in. Therefore, the humidity inside the first partition device 210 can be kept low, and the ozone generation efficiency in the ozone generator 200 can be maintained in a high state. In addition, in this embodiment, the upper part of the first partition device 210, that is, the The peripheries of the ozone generator 200 and the like are maintained at a lower temperature.

In addition, when the ozone generator 200 is selected to generate ozone by high voltage, the ozone generator 200 is installed near the cold air outlet 213 where the temperature distribution in the storage room becomes low due to the cold air flowing in from the storage room. Thereby, the inside of the first partition device 210 becomes low temperature, and ozone can be generated with high efficiency. Therefore, power consumption required for ozone generation can be suppressed, and energy saving can be contributed.

In addition, the first partition device 210 can adjust the ozone in 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 inside of the first partition device 210 from the suction hole 212, and the amount of ozone flowing out from the discharge hole 211. concentration.

That is, the first partition device 210 determines the total opening area of the discharge holes 211 and the total opening area of the suction holes 212 provided on the first partition device 210 at the design stage, so that the ozone concentration of the vegetable compartment 120 can be adjusted to some extent. Specifically, when there are many discharge holes 211 (total opening area is large), the outflow amount of ozone is large, and the ozone concentration in vegetable compartment 120 is high. 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 within the capability limit of the ozone generator 200 . On the contrary, when there are few discharge holes 211 (total opening area is small), the outflow of ozone is small, and the ozone concentration of the production upper 120 is low.

In addition, the first partition device 210 flows out ozone and flows in oxygen by natural convection, but a fan may be used to force ozone to flow out and oxygen to flow in. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the storage container 121, and adjust (for example, switch on and off the fan) the ozone generation amount of the ozone generator 200 according to the information from the cover ozone concentration meter, so that the storage container The ozone concentration within 121 was kept within the specified range.

It is preferable to maintain the ozone concentration in the vegetable room 120 or the storage container 121 which is a food storage room at 0.05 ppm or less. This is because there is concern that when the ozone concentration is high, when the storage container 121 is drawn out or food such as vegetables is taken out from the storage container 121, any influence will be given to the human body performing these operations. In addition, it is preferably maintained at 0.03 ppm or less. This is because when the ozone concentration is high, the odor of ozone will give discomfort to the person who performs the work.

In addition, the first light source 220 is an activation promoting device that promotes the decomposition of harmful substances such as agricultural chemicals in this embodiment, and emits light of a predetermined wavelength that activates the biological defense reaction of fruits and vegetables stored in the vegetable compartment 120 serving as a storage compartment. Diodes (LEDs). The activated fruits and vegetables increase the types of vitamins as antioxidant substances and release antioxidant substances, so that harmful substances such as pesticides are decomposed by ozone, and the pesticides attached to the surface of fruits and vegetables are decomposed by the increased vitamins in the fruits and vegetables. and other harmful substances. Thereby, it is possible to promote the ozonolysis of agricultural chemicals.

The first light source 220 is provided in the upper part of the upper container 123 which is also called a fruit box and is suitable for storing fruits, which is also in the storage container.

In addition, the first light source 220 is disposed inside the first partition device 210 . This is to prevent the dew condensation of the first light source 220 from absorbing light of a predetermined wavelength and reducing the decomposition efficiency of pesticides.

Therefore, at least the first partition device 210 is preferably made of a material capable of sufficiently transmitting light of a necessary wavelength among the light emitted from the first light source 220 .

In addition, in order to more efficiently activate the biological defense reaction of fruits and vegetables, the LED element of the first light source 220 preferably uses blue light with a center wavelength of 470 nm as the wavelength for penetrating light into the surface of fruits and vegetables, and as a wavelength for penetrating light into the interior of fruits and vegetables. The wavelength uses green light with a center wavelength of 520nm. At this time, the irradiation intensity from the first light source 220 provided with blue LEDs and green LEDs for irradiating objects (fruits and vegetables) is suitable for 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 the antioxidant substance, that is, the vitamin that increases the defense reaction of the living body as a light irradiation. In addition, if the irradiation intensity is weak to less than 5 lx, it will be difficult for the user as a consumer to recognize the brightness of the lighting when the door is opened and closed, so it is difficult to obtain the actual installation in the refrigerator. The effect appeal of the product and other appeal effects.

On the other hand, if it exceeds 500lx, the light intensity will be too strong, and the water evaporation of fruits and vegetables will be promoted on the contrary, and the freshness may be reduced. In addition, depending on the situation, the irradiated light may be bent or discolored, and the functional quality may deteriorate. Also, when the amount of light increases when the door is opened and closed, it tends to be difficult for the user as a consumer to enjoy the refreshing feeling as a refrigerator.

Based on these, as the amount of light of the first light source 220, the brightness range of 20 to 100 lx is used as an effective range to realize the increase of vitamins as antioxidant substances without promoting the evaporation of water in fruits and vegetables in terms of functions, and as an effective range when the door is opened and closed on the sensory surface. A brightness range in which the user can appreciate the functional effect of the light irradiation from the first light source 220 and enjoy a refreshing feeling is more preferable.

In addition, the irradiation intensity of the green light is preferably stronger than that of the blue light. In this embodiment, the ratio of the luminance of the green LED to the luminance 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 brightness of the storage space itself can be increased or decreased by a luminance meter. Specifically, when two colors are irradiated at the same time, changing the switching of the control board, etc., irradiating each color and measuring the respective luminances, it is possible to confirm the intensity of each wavelength, that is, the luminance of each color.

In this way, since green light is light of a wavelength with little side effects on fruits and vegetables, in order to increase the amount of vitamins in fruits and vegetables as an antioxidant substance and enhance the brightness of green light penetrating into fruits and vegetables, the quality of fruits and vegetables will not be deteriorated and the vitamins will be damaged. amount increased. According to experiments, it has been found that it is effective to set the luminance of the light in the range of about 3 to 10 times that of the green light as that of the blue light. That is, at a level of less than 3 times, the effect of increasing the amount of vitamins inside fruits and vegetables is insufficient, and at a level of more than 10 times, it is difficult to expect the effect of increasing the amount of vitamins on the surface of fruits and vegetables, and it is difficult to obtain a comprehensive result in either case. The effect of increasing the amount of vitamins.

In addition, the intermittent irradiation of fruits and vegetables can stimulate the vegetables more than the continuous lighting irradiation. In addition to photosynthesis to generate vitamin C, it can also promote the generation of vitamin C as an antioxidant in the defense reaction of vegetables, which can further promote the harmful effects of pesticides and other harmful substances. substance removal. Therefore, the first light source 220 is preferably controlled to flash and illuminate (intermittently illuminate) the green LED and the blue LED simultaneously at any frequency in the range of 20-50 Hz around 40 Hz.

This causes a problem that, in the case where the slow flickering of 20 Hz or less can be clearly recognized by the user as flickering of intermittent illumination, the flickering of the light feels a warning such as notifying any abnormality, or a sense of psychological pressure is felt when the flickering continues to be sluggish. , or angry emotions such as irritability caused by visual stimulation.

In addition, such a frequency of 20 Hz to 50 Hz performs flicker irradiation at a frequency of 50 Hz or less, that is, in other words, a power supply frequency in China, Japan, or European countries. Therefore, by using a frequency lower than the power supply frequency, the reliability of the first light source 220 can be improved by flickering at a frequency lower than that of an illuminating device or LED used at a commonly used power supply frequency.

In addition, the wavelengths emitted by the first light source 220 are blue or 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 this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, it is preferable that the wavelength of the strongest absorption portion corresponds to a valley portion of the spectrum, for example. For example, "-CH ₃ " exists as a functional group in a large amount in the molecular structure of harmful substances such as pesticides, and the infrared absorption spectrum of this "-CH ₃ " functional group is 3378nm (wavenumber 2960/cm) and 3484nm (wavenumber 2870/cm) . Therefore, wavelengths in the infrared region including 3378 nm (wave number 2960/cm) and 3484 nm (wave number 2870/cm) are used as the wavelength emitted by the first light source 220 . Then, the light emitted from the first light source 220 is likely to be decomposed in the “-CH3” portion of harmful substances such as pesticides.

In addition, it is preferably obtained from organophosphorus pesticides such as chlorpyrifos (chlorpyrifos, chlorpyrifos), malathion (malathion, malathion) or quinalphos (kinalhos, quinalphos), or pyrethroids such as permethrin (permethrin). (pyrethroid, pyrethroid) the wavelength determined by the infrared absorption spectrum of pesticides. These are pesticides that are used in large quantities in food and have a high possibility of remaining in food. In addition, organophosphorus pesticides are highly toxic pesticides compared with other types of pesticides, and their safety to the human body can be further improved by removing them as much as possible. In addition, since the wavelengths of these infrared rays exist in the range of 1250nm (wavenumber 800/cm) to 3333nm (wavenumber 3000/cm), the wavelength emitted by the first light source 220 is preferably in this wavelength range.

Moreover, the 1st light source 220 can also be used as an ozone activation device by including the wavelength of ozone activation in the infrared wavelength of the 1st light source 220. For example, it is a wavelength in the infrared region that ozone absorbs. This is because when ozone is activated, decomposition of harmful substances such as agricultural chemicals is promoted.

Therefore, wavelengths including the infrared region can also be used as an ozone activator that activates harmful substances such as pesticides and ozone at the same time, and has an additive effect of decomposing pesticides at a lower concentration of ozone.

In addition, the light emitting mode of the first light source 220 is preferably a mode that easily decomposes harmful substances such as pesticides. The way of the first light source 220 . The predetermined value is preferably 0.01 ppm or more in consideration of the decomposition efficiency of harmful substances such as pesticides. It is also an effective means to blink the first light source 220 at light emission intervals corresponding to multiples and submultiples of the natural frequency of the molecules constituting the agricultural chemical. Thus, light energy can be efficiently injected into the pesticide, and molecular coupling of harmful substances such as the pesticide can be easily broken and decomposed by ozone.

In addition, in this embodiment, a light emitting diode is used as the first light source 220, but it is not particularly limited, and the first light source 220 that emits light may be used. In addition, when a structure in which a plurality of light emitting diodes emitting lights of different wavelengths is combined is used as the first light source 220, a multi-layered effect can be further obtained.

In addition, in the present embodiment, the first light source 220 is used as the activating device, but the ozone gas generated from the ozone generator 200 can also be used as a device for activating the biological defense reaction of vegetables. There is vitamin C as an antioxidant released when the living defense reaction of fruits and vegetables is activated, but when 0.03ppm ozone gas is stored in spinach for 24 hours, the vitamin C of spinach before storage is 73.5mg/100g, compared to This storage increased to 83.8mg/100g. When ozone gas is used as an activation device for activating the defense reaction of fruits and vegetables in this way, the first light source 220 need not be provided, and the ozone generating device 200 can be used as an activation promotion device, so there is no room for installation in terms of manufacturing cost. Therefore, it is more effective in terms of being able to store food in a larger space.

In addition, food storage 100 is provided with a cooling device. In the case of this embodiment, as shown in FIG. 2 , the cooling device is constituted by a cold air cycle provided with two coolers. Specifically, a first cooler 112 a is provided on the rear side of the inner portion of the refrigerating room 110 . The inner portion of the refrigerator compartment 110 is cooled by heat conduction from the first cooler 112a. The air in the refrigerator compartment 110 is cooled by the cooled inside.

Moreover, the 2nd cooler 112b is provided in the rear side of the back of the freezer compartment 130. As shown in FIG. The inside of freezer compartment 130 is cooled by the cold air forcibly passing through second cooler 112b, and the cold air for cooling food etc. returns to second cooler 112b again.

The cool air released from the second cooler 112 b is also supplied to the vegetable compartment 120 through the cool air outlet 213 . Vegetable compartment 120 is controlled to control the amount of cool air supplied by opening and closing 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 to maintain the temperature within the range of 4°C or lower and 0°C or higher.

Fig. 4 is a perspective view showing a lid of the food storage in Embodiment 1 of the present invention. Storage container 121 is a box body arranged in vegetable compartment 120 serving as a storage compartment, and having opening 127 opened upward so as to be drawn out.

The lid 122 is a plate-shaped member that closes the opening 127 of the storage container 121 , and has a passage hole 124 and an adjustment hole 125 . In addition, the cover 122 is made of a material capable of sufficiently transmitting light of a necessary wavelength among the light emitted from the first light source 220 . The cover 122 has the function of adjusting the humidity in the storage container 121, specifically, it can maintain the moisture evaporated from the vegetables stored in the storage container 121 to some extent in the storage container 121, and at the same time adjust the humidity in the storage container 121. 121 to the extent that moisture does not condense.

Fig. 5 is a cross-sectional view of a passage hole of a cover of the food storage in Embodiment 1 of the present invention. 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 tapered shape gradually increasing in diameter 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 storage container 121 .

By forming the passage hole 124 in the above-mentioned shape, the ozone falling from the discharge hole 211 of the first partition device 210 can be received by the larger diameter portion of the passage hole 124 and the ozone can be efficiently introduced into the storage container 121 . On the other hand, the moisture existing inside the storage container 121 can match the outflow amount of the adjustment hole 125 described later, and the humidity inside the storage container 121 can be adjusted according to the design.

About the food storage comprised as mentioned above, the operation|movement and effect|action are demonstrated below.

First, the ozone generator 200 located in the vegetable compartment 120 is driven to generate ozone, and the vegetable compartment 120 for storing fruits and vegetables is filled with ozone gas. At this time, the filled ozone gas has a low concentration of 0.03ppm. Moreover, the filled low-concentration ozone gas contacts harmful substances such as pesticides attached to the surface of fruits and vegetables, and these harmful substances oxidize and decompose with ozone to decompose into harmless safe substances. In addition, while using the decomposition and removal of ozone gas, light is emitted from the first light source 220 to activate the biological defense reaction of fruits and vegetables, and increase the release of vitamin C as an antioxidant substance. Oxidative decomposition of harmful substances such as pesticides.

In addition, here, the first light source 220 adopts an activation device, but the first light source 220 can also be omitted, and the ozone gas emitted from an ozone generator can be used as an activation device, and its effect can also be confirmed according to experiments, so in the following Be explained.

6 is a diagram for confirming the difference in the pesticide removal performance of the pesticide on the shelf (glass plate) of the food storage according to Embodiment 1 of the present invention and on the fruits and vegetables. In this experiment, ozone gas emitted from the ozone generator 200 was used for the activation device.

Experimental method The ozone generator 200 was driven, and the ozone concentration in the vegetable compartment 120 was 0.03 ppm. At the same time, the ozone gas generated from the ozone generator 200 is also used as an activation device. 0.0067 μg/cm ² of organophosphorus pesticide malathion was attached to both a 10 cm diameter glass plate bowl (シヤレ) and stalks cut into 4×4 cm, and then put into the vegetable compartment 120 . Thereafter, the decomposition and removal treatment was performed for 24 hours, the amount of malathion after the treatment was measured by GC/MS (gas chromatography spectrometer), and the removal rate of malathion was calculated. In addition, the temperature of the vegetable compartment 120 at this time is 4 degreeC.

As a result of the experiment, the removal rate of malathion on the dish was 46%, and the removal rate of malathion on stalks was 93%. That is, the results of the removal effect of malathion using only ozone can be confirmed by the dish, but even under the same conditions of storage in the ozone, the removal of malathion in the dish on the glass plate and the stalks on the fruits and vegetables can be seen. Rates are different. That is, the malathion on the stalks can remove a large amount of malathion up to twice as much as that on the dish.

This means that ozone gas itself activates the biological defense reactions of fruits and vegetables, promotes the production of antioxidants such as vitamin C, and promotes the decomposition and removal of malathion from the antioxidants such as vitamin C produced from the inside of fruits and vegetables. That is, malathion can be decomposed more efficiently by activating fruits and vegetables with ozone gas to generate antioxidant substances than by removing harmful substances such as pesticides only with ozone gas.

Thus, ozone gas can also function as an activator for activating the biological defense reaction of fruits and vegetables to promote the generation of antioxidant substances, and it has been shown that it is very effective as an activator for promoting the ozonolysis of harmful substances. From this, it can be confirmed that even low-concentration ozone gas, which is safer for the human body, can activate the biological defense reactions of fruits and vegetables, and utilize this to promote the decomposition and removal of harmful substances such as pesticides, and can fully remove harmful substances such as pesticides. substance.

In addition, experiments are further advanced here, and when the types of fruits and vegetables and pesticides are different, it is confirmed how ozone gas acts as an activation device, and it will be described below.

7 is a graph for confirming the pesticide removal performance of the types of fruits and vegetables in the food storage according to Embodiment 1 of the present invention. In this experiment, the activation device used the ozone gas generated from the ozone generator 200 .

Experimental method The ozone generator 200 was driven, and the ozone concentration of the vegetable compartment 120 was 0.03 ppm. At the same time, the ozone gas emitted from the ozone generator 200 is used as an activation device. At this time, a product obtained by attaching 2 ppm of quinthion to stalks cut into 4 x 4 cm was thrown in, and after 24 hours of treatment, washing was performed with 1 L of distilled water for 30 seconds. After the treatment, the amount of quinthion was measured by a gas chromatograph mass spectrometer (Gas Chromatograph Mass Spectrometer: GC/MS (gas chromatography)), and the removal rate of quinthion was calculated. In addition, in order to clarify the removal effect of only utilizing ozone gas, as a comparison, the stalks with the same amount of quinthion were not thrown into the vegetable compartment 120, and the samples that were only washed with 1 L of distilled water for 30 seconds were also analyzed by GC/MS ( GC-MS) to measure the amount of Quetiaphos, and calculate the removal rate of Quetiaphos. The same experiment was carried out using apples as fruits under the same conditions as stalks, and the pesticide removal effect by ozone gas was confirmed. In addition, the temperature of the vegetable compartment 120 at this time is 4 degreeC.

As a result of the experiment, the removal rate of quinthion in the initial water washing of scallops was 2%, and the removal rate of quinthion in water after the pesticide removal treatment in the vegetable compartment 120 for 24 hours was 25%.

On the other hand, the removal rate of quinthion in the initial water washing of apples was 7%, and the removal rate of quinthion in water after 24 hours of pesticide removal treatment in the vegetable compartment 120 was 38%.

From this, it can be seen that the removal amount of quetiaphos in the vegetable compartment 120 after the pesticide removal for 24 hours and washing with water was very large compared to the removal amount of quetiaphos in the stalks and apples which were only washed in the initial stage. That is, even if the types of fruits and vegetables and the types of pesticides are different, harmful substances such as pesticides adhering to fruits and vegetables can be decomposed and removed by storing them in the low-concentration ozone gas environment vegetable compartment 120 in the first embodiment.

In addition, on the other hand, if the removal rate of quinaphos by ozone gas treatment and water washing of stalks is compared with the removal rate of quinaphos by ozone gas treatment and water washing of apples, it can be seen that stalks and apples are significantly removed. rate is different. Specifically, the removal rate of stalks under the same conditions was 25% and that of apples was 38%. This means that depending on the type of fruit and vegetable, the activation level of the biological defense reaction produced by ozone gas is also different. Compared with the stalks which are green vegetables, the antioxidant substances brought about by the biological defense reaction of apples as a fruit are more produced.

Then, it was confirmed that not only the ozone gas emitted from the ozone generator but also the pesticide itself was used as the activation device, and the decomposition of harmful substances such as pesticides was further promoted by the ozone gas and light by the irradiation of light from the first light source 220. , to remove harmful substances such as pesticides more efficiently, so it will be explained below.

FIG. 8 is a diagram for confirming the accelerating performance of harmful substances such as agricultural chemicals in the first light source 220 of the food storage according to Embodiment 1 of the present invention.

Experimental Method First, the ozone generator 200 of the vegetable compartment 120 was driven, and the ozone concentration of the vegetable compartment 120 was 0.03 ppm, and at the same time, the first light source 220 was driven. In addition, the lighting conditions of the first light source 220 were three conditions: non-lighting, continuous lighting, and blinking at 40 Hz, and each pesticide removal performance was compared. At this time, 4 cm × 4 cm stalks in which 8 ppm of permethrin, which is a pyrethroid pesticide, was adhered to the stalks were kept for 24 hours. The pesticide removal amount at this time was measured by GC/MS (mass spectrometry), and the removal rate was obtained. In addition, the temperature of the vegetable compartment 120 at this time is 4 degreeC.

As a result of the experiment, the permethrin removal rate of the stalks kept in the vegetable compartment 120 for only 24 hours under the condition of no light (without using the first light source 220) was 26%. The removal rate was 38%, and the removal rate of stalks under the flashing light was 46%.

Thus, by driving the first light source 220, compared with removing harmful substances such as pesticides only by ozone gas under the condition of no light (without using the first light source 220), by using the ozone gas and the first light source 220 together, it is possible to display more Efficiently removes harmful substances such as pesticides.

This is considered to be that ozone gas functions as an activator for activating the living body defense reactions of fruits and vegetables, and light mainly functions as an activator for activating the pesticide itself, so that the pesticide is activated to form a decomposed easier state. The inventors think that the pesticide is in a state where it is easier to decompose in this way. In addition, light functions as an activation device for activating the biological defense reaction of fruits and vegetables on the basis of ozone gas, and is easily decomposed by the production of antioxidant substances. The pesticides further have a synergistic effect of promoting decomposition by the antioxidant substances of the fruits and vegetables themselves.

In addition, the light of the first light source 220 can be displayed to remove harmful substances such as pesticides more efficiently when blinking compared to continuous lighting.

The inventor thinks that by flickering the first light source 220, compared with continuous irradiation, the stimulation is stronger, so the pesticide can be more activated, and the pesticide can be easily decomposed, and the defense reaction of the stem can be further promoted. The light source 220 functions as an activating device for activating pesticides, and also functions as a device for activating the living defense reactions of fruits and vegetables. The oxidizing species further promotes the synergistic effect of decomposition.

In addition, in this experiment, the following effects are expected as the wavelength of light, and blue and green light are used.

First, by using blue having a peak wavelength around 400 nm to 500 nm, it is possible to prevent degradation of synthetic resins widely used in refrigerators, etc., compared with ultraviolet wavelengths and the like. Therefore, it is possible to suppress quality deterioration such as lipid oxidation in long-term storage foods, and to suppress the growth of bacteria or mold as a unique effect of blue wavelengths. Therefore, it is possible to keep the inside of the cabinet of the refrigerator and the surface of preserved objects or fruits and vegetables clean. In addition, when installed in an actual refrigerator, there is also a sensory effect of giving the user a sense of cleanliness due to the refreshing feeling of blue.

In addition, by using green having a peak wavelength around 500 nm to 600 nm, it is possible to prevent degradation of synthetic resins widely used in refrigerators, etc., compared with ultraviolet wavelengths and the like. Furthermore, since the action light unique to the green wavelength penetrates into the inside of the fruit and vegetable, it can promote the action on the inside of the fruit and vegetable, and the biological defense reaction from the inside side can further increase nutrients such as vitamins.

Thus, when the first light source 220 emits combined blue wavelength and green wavelength light, the blue wavelength light can suppress the growth of fungi on the surface of fruits and vegetables, and the green wavelength penetrating into the fruits and vegetables can also promote the growth of fungi inside the fruits and vegetables. The living defense reaction can further improve the preservation of fruits and vegetables.

In addition, regarding the irradiation method of the above-mentioned light, the above-mentioned effect can also be obtained by continuous irradiation, but the stimulation can be made stronger by flashing irradiation, so the effect of inhibiting the growth of bacteria in blue is enhanced, and in addition, the blue light can promote the growth of the surface of fruits and vegetables. in vivo defense responses. In the same way, green can further promote the defense of the living body from the inside, so it is an effective irradiation method.

As above, the food storage 100 of the present invention activates harmful substances such as pesticides remaining on stored fruits and vegetables or food by irradiation of light as an activation device, and the food is easily decomposed. Therefore, even low-concentration ozone gas that has no effect on the human body can effectively 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 it is possible to decompose residual pesticides while storing food for a long time.

Furthermore, since the ozone gas also has the effect of reducing the etching gas, food such as vegetables can be prevented from being deteriorated, such as turning brown by the etching gas.

In addition, fruits tend to have more pesticide residues than vegetables, so in this embodiment, the first light source 220 as an activation device that can further increase the removal rate of pesticides by activating pesticides is also installed in the storage container. The upper part of the upper container 123 suitable for storing fruits, which is called a fruit box. Like this, the first light source 220 is installed on the upper part of the upper container 123 suitable for fruit storage, so that the pesticide removal rate of the fruit stored in the upper container 123 can be improved, so 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 standard (positive risk) of fruits and vegetables, the residual pesticide standard of quinthion, which is an organophosphorus pesticide, is the same value as 1 ppm for stalks and 1 ppm for apples. However, if 1ppm of the residual pesticide standard value is converted into the weight of pesticides, one leaf of scallops is about 20g, and that of apples is 300g. Therefore, the residual pesticide amount of quinthion in 20g of stalks is 20mg, and the amount of quinthion in 300g of apples The residual pesticide amount is 300mg. That is, for example, with the same residual pesticide standard value, it was confirmed that more pesticide residues adhered to apples with a larger specific gravity than to stalks with a lighter specific gravity. In addition, fruits such as apples or oranges are often waxed during distribution.

Thus, in the present embodiment, the storage container 121 as the section mainly storing vegetables and the upper container 123 as the main section accommodating fruits are formed separately, and the removal rate of harmful substances such as pesticides in the upper container 123 as the section mainly accommodating fruits is formed. As a whole, the vegetable room can further promote the removal of harmful substances such as pesticides, and provide consumers with more secure food.

In this way, when the first light source 220 as the activating device for activating the pesticide itself is disposed directly above the upper container for mainly storing fruits, the upper container is made of a light-transmitting material, and light is irradiated to the storage container 121 through the upper container. . Thereby, on the basis of the upper container 123 that decomposes the agricultural chemicals more easily, light is also irradiated to the storage container 121, so that although the amount of irradiation is small compared with the upper container 123, since the light is irradiated, the removal of harmful substances can be further promoted. remove.

In addition, for example, in yellow-green vegetables such as stalk vegetables, strong light irradiation promotes the evaporation of water from the vegetables, and the water content in the vegetables decreases. In this case, as described above, the first light source 220 irradiates the section mainly storing fruits with a stronger light intensity, so that the light irradiated on the section mainly storing vegetables passes through the upper container 123, so the light intensity can be reduced. Therefore, the first light source 220 can be installed without the main risk of the moisture in the vegetables being reduced. In addition, because the surface of fruit is generally covered with skin, compared with yellow-green vegetables such as scallops, there is less water evaporation caused by light irradiation, and there is no need to worry about water loss caused by light. Therefore, the storeroom structure of this embodiment is also a reasonable structure from a viewpoint of maintaining the freshness of fruits and vegetables.

In addition, the ozone generator 200 is preferably installed in front of the storage container 121 . This is because the upper container 123 is provided at the rear of the storage container 121, so when the ozone generator 200 is arranged at the rear, the ozone gas is temporarily stored in the upper container 123 as a smaller storage partition, and the stored gas diffuses. To the storage container 121, the storage container 121 cannot be filled more efficiently. Therefore, ozone can be further improved by releasing ozone around the inside of storage container 121 , which is a large storage partition provided avoiding the front of the upper container 123 .

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

In addition, the storage box 170 may be partitioned by a fixed heat insulating wall, and may be partitioned by a partition plate not limited to a heat insulating material when partitioning by a heat insulating wall is not particularly necessary.

Alternatively, the activating means may employ light that includes the visible region. In this case, the food stored in the storage container 121 is irradiated by the light-emitting diode, and the food can be seen without opening the storage container 121, so usability is improved. In addition, the number of times of opening the storage container 121 is reduced, and the ozone gas generated in the storage container as a food container is less released to the outside, so there is also an effect of removing harmful substances such as agricultural chemicals.

In addition, the second partition member 328 and the cover 330 are separate components, but are not particularly limited. The shape of the second partition device 328 is a shape capable of sealing the third storage box 315 , and may not have a cover 330 .

In addition, in this embodiment, the second partition device 328 is provided between the third storage box 315 and the ozone generator 327, which become high-humidity due to the evaporation of moisture from the vegetables, so that the second partition device 328 can be The upper part, that is, the periphery of the ozone generator 327 is maintained at a lower humidity.

Moreover, when the type of the ozone generator 327 adopts the type which generates ozone by high voltage, the 3rd storage box 315 is installed in the lowest position in the temperature distribution of the refrigerator compartment 304. Accordingly, the ozone generator 327 is also installed in a low-temperature region, and ozone can be generated with higher efficiency. Therefore, power consumption required for ozone generation can be suppressed, and energy saving can be contributed.

In addition, the second light source 329 as an activation device is an activation promotion device for promoting decomposition of harmful substances such as agricultural chemicals in this embodiment. In addition, the second light source 329 is a light emitting diode (LED) that activates the biological defense reaction of fruits and vegetables stored in the third storage box 315 and emits the same predetermined wavelength as the first light source 220 described in Embodiment 1. . Activated fruits and vegetables have increased vitamins as antioxidant substances, and decompose harmful substances such as pesticides by ozone, and decompose harmful substances such as pesticides attached to the surface of fruits and vegetables by vitamins increased in fruits and vegetables. Thereby, the decomposition of pesticides by ozone can be accelerated.

In addition, the second light source 329 is arranged inside the partition plate 326 . This is because the dew condensation of the second light source 329 absorbs light of a predetermined wavelength, thereby preventing a decrease in the decomposition efficiency of the pesticide.

Therefore, at least the second partition means 328 is preferably made of a light-transmitting material so as to sufficiently transmit light of a necessary wavelength among the light emitted by the second light source 329 as the activation means.

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 form a liquid refrigerant. The refrigerant condensed by the condenser 305 flows to the first decompression device or the second decompression device through the switching valve, and is a decompressed low-pressure and low-humidity gas-liquid two-state refrigerant.

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

In addition, the refrigerant flowing from the switching valve to the second decompression device flows from the refrigerating evaporator 309 to the freezing evaporator, and evaporates in the refrigerating chamber 304 and the freezing chamber 303, thereby cooling the refrigerating chamber 304 and the freezing chamber by the heat of evaporation and vaporization. Chamber 303 is cooled and sucked again into the compressor.

Here, the cold air obtained by the heat of evaporation and vaporization of the liquid refrigerant in the refrigerating evaporator 309 flows in the refrigerating cooling air passage 316 through the fan 317, 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 the respective partitions.

Moreover, the inside of the 2nd storage box 314 and the 3rd storage box 315 is cooled by the return air which cools the subregion other than these, and flows inside and outside a box.

Then, 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 causes the liquid refrigerant in the refrigeration evaporator 309 to evaporate due to the temperature difference, and the heat is taken away to form a low temperature, and then The fan 317 is directed into the cabinet to cool the partitions.

Next, the ozone generator 327 located in the third storage box 315 is driven to generate ozone gas. At this time, the third storage box 315 for storing fruits and vegetables is filled with ozone gas. At this time, the filled ozone gas has a low concentration of 0.03ppm. Then, the filled low-concentration ozone gas contacts harmful substances such as pesticides attached to the surface of fruits and vegetables, and these harmful substances undergo oxidation and decomposition reactions with ozone to further reduce harmful substances and decompose them into safe substances. In addition, while the ozone gas is decomposed and removed, light is emitted from the second light source 329 to activate the biological defense reaction of fruits and vegetables, and to increase the release of vitamin C as an antioxidant substance. Oxidative decomposition of harmful substances such as pesticides.

In addition, at this time, the ozone generating device 327 and the third storage box 315 are located at the bottom of the refrigerator compartment 304, that is, the ozone generating device 327 is arranged in the storage partition located at the bottom, so the ozone heavier than air can be efficiently released to the refrigerator. The third storage box 315 slides and stagnates. Thus, a small amount of ozone, such as 0.03 ppm, can be efficiently filled in the third storage box 315 reliably, and the antibacterial of the third storage box 315 and the antibacterial preservation of food can be improved, and the amount of ozone attached to the food can be reduced. Harmful substances such as pesticides can further improve food safety.

In addition, since the third storage box 315 is located at the bottom, even when the ozone flows out of the refrigerator due to taking out and putting in the food, the high-concentration ozone can be used to quickly flow out to the bottom, and the user can feel it through the mouth and nose. The possibility of inhaling ozone into the body is reduced, and a safer refrigerator can be provided.

In addition, on the other hand, after the cold air blown out from the first outlet 318, the second outlet 319, the third outlet 320, and the fourth outlet 321 is cooled by natural convection to the third storage box 315, it is drawn into the second inlet. 323 suction, and then return to the evaporator 309 for refrigeration. In the circulation of such cold air, after the ozone gas generated from the ozone generator 327 flows into the third storage box 315, a part of the ozone gas is sucked from the second suction port 323 by the air flow of the cold air circulation, and blows into the first blower. The outlet 318, the second outlet 319, the third outlet 320, and the fourth outlet 321 circulate. Therefore, the ozone gas spreads over the entire refrigeration cooling air passage 316 and the refrigerator compartment 304 . Thereby, not only the third storage box 315, but also the refrigerating and cooling air passage where miscellaneous bacteria are more likely to multiply can be concentrated by ozone antibacterial, and the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food can be realized more reliably. And reducing harmful substances such as pesticides attached to food can further improve food safety.

In addition, since the ozone generating device 327 is provided in the storage compartment located at the most downstream side in the refrigerating room 304, the storage compartment located at the most downstream side of the refrigerating and cooling air passage flows into the cold air containing bacteria and the like in each storage compartment. . Therefore, even though it is an environment where miscellaneous bacteria are easy to multiply in general, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of antibacterial preservation in storage rooms based on refrigeration temperature zones and the antibacterial preservation of food, and reduce the amount of bacteria attached to food. Harmful substances such as pesticides can further improve food safety.

In addition, the ozone generator 327 does not need to be specially installed on the partition plate 326 , and may also be installed in the refrigeration cooling air passage 316 . Thereby, antibacterial can be reliably achieved by ozone in the refrigerating and cooling air passage where miscellaneous bacteria are easy to multiply, and the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food can be realized more reliably, and the reduction of adhesion to food can be achieved. Harmful substances such as pesticides on the surface can further improve food safety.

In addition, the ozone generating device 327 may also be provided in the storage room or storage partition with the highest temperature among the storage rooms in the refrigerated temperature zone. Thus, due to the high temperature, even though it is an environment where bacteria are easy to multiply, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigerated temperature zone and the antibacterial preservation of food, and reduce Harmful substances such as pesticides attached to food can further improve food safety.

As mentioned above, in the food storage 300 of this invention, the ozone generator 327 and the 3rd storage box 315 are located in the lowermost part of the refrigerator compartment 304. As shown in FIG. Therefore, ozone heavier than air can efficiently slip into the third storage box 315 , and a small amount of ozone, such as 0.03 ppm, can be efficiently filled in the third storage box 315 reliably. Therefore, it is possible to improve the antibacterial preservation by the third storage box 315 and the antibacterial food, and to reduce harmful substances such as agricultural chemicals adhering to the food, and to further improve the safety of the food.

In addition, in this embodiment, a cover 330 is provided in the third storage box 315, but the present invention is not limited thereto, and the third storage box 315 and its cover 330 may not be present, and the storage space divided by the partition plate 326 may be Store food directly in the space. Alternatively, the second partitioning device 328 and the cover 330 are separately formed structures, but it is not particularly limited. The shape of the second partitioning device 328 can also be formed into a shape in which the third storage box 315 can be sealed, and a shape without the cover 330 can be formed. .

In addition, the refrigerator compartment door 308 adopts a revolving door, but it is not limited to this, and multiple doors can also be used. The third storage box 315 adopts a storage box pulled out from a pull-out door. The way the third storage box 315 is stored.

(3 in the embodiment)

Fig. 12 is a front view showing the refrigerator according to Embodiment 3 of the present invention. As shown in this figure, the food storage 400 is a refrigerator which has three doors 411a, 411b, 411c, and the storage room formed by the heat insulation box 470 is divided into three.

The food storage 400 has a refrigerator compartment 410, a vegetable compartment 420, and a freezer compartment 430 from above as divided storage compartments. In this figure, the rectangular dotted lines indicate the openings of each storage room, and foods to be stored are carried in from the front and carried out from the heat-insulating box 470 partitioned in the shape of a partition.

Moreover, the food storage 400 is provided with the door 411a, 411b, 411c which can airtightly open and close the heat insulation box 470. As shown in FIG. Specifically, the food storage room 400 is provided with a door 411a capable of opening and closing the refrigerator compartment 410, a door 411b capable of opening and closing the vegetable compartment 420, and a door 411c capable of opening and closing the freezer compartment 430. The doors 411a, 411b, and 411c can be opened and closed by hinges. Closely installed on the heat insulation box 470.

The heat insulation box 470 has the function of insulating the outside and the inside. As shown in the ellipse in the figure, it is equipped with an inner box 471 vacuum-formed by resin such as ABS and an outer box 472 suitable for metal materials such as pre-coated steel plates. The heat insulating material 473 between the inner case 471 and the outer case 472 constitutes. In addition, the door 411 is also comprised from the inner panel, the outer panel, and the heat insulating material 473 similarly.

Fig. 13 is a longitudinal sectional view of the refrigerator according to Embodiment 3 of the present invention.

As shown in the figure, the food storage 400 is provided with an ozone generator 500, a third light source 520, and a first cover member 510 as an adjustment member for adjusting the action of the additional function device as additional function devices. Moreover, the food storage 400 is provided with the storage container 421 and the cover 422 inside the vegetable compartment 420 .

The ozone generator 500 as an additional function device is a device capable of generating ozone to be supplied to the storage container 421 arranged in the storage room. Ozone generator 500 is buried on the lower surface side of heat insulating wall 415 which partitions refrigerating room 410 and vegetable room 420 toward the inside of vegetable room 420 . Therefore, the ozone generator 500 is arranged above the opening 427 of the storage container 421 described later, at a position away from the opening 427 of the storage container 421 , and is arranged at a position facing the opening 427 .

Thus, by burying the ozone generator in the heat insulating wall 415, even if the temperature of the vegetable compartment 420 changes, the temperature of the ozone generator 500 is hard to change, and ozone generation efficiency can be maintained stably.

Here, the ozone generation efficiency 500 is not particularly limited as long as it is a device capable of generating ozone. Specifically, an apparatus that irradiates ultraviolet rays to oxygen molecules (O ₂ ) in the air to generate ozone (O ₃ ) or an electrode placed in the air at a high voltage to convert oxygen molecules in the air to Devices for ozone, devices that electrolyze oxygen-containing substances such as water, and supply ozone to the air, etc.

Fig. 14 is a partial sectional view of an adjustment member of the refrigerator according to Embodiment 3 of the present invention.

The adjustment member for adjusting the function of the additional function device is the first cover member 510 disposed inside the storage room of the ozone generator 500 as the additional function device, and made of a thin plate separating the ozone generator 500 and the storage room. That is, as shown in FIG. 14 , the first cover member 510 in the shape of an inverted quadrangular truncated pyramid is provided with a plurality of release holes 511 in front of the lower surface. In this case, the first cover member 510 as an adjustment member is provided with a plurality of release holes 511, so that the ozone generated from the ozone generator 500 of the additional function device can adjust the amount of ozone released into the vegetable compartment 420 as a storage compartment. . That is, the amount of ozone flowing into vegetable compartment 420 is determined by the size and number of discharge holes 511 . In addition, the ozone emission range at the time of emission from the ozone generator 500 into the vegetable compartment 420 can be adjusted by the location where the emission hole 511 is provided.

In this way, the first cover member 510 as an adjustment member for adjusting the function of the additional function device covers the ozone generator 500 embedded in the heat insulation wall 415 and is installed on the lower surface of the heat insulation wall 415, that is, beyond the ozone generator. 500, the inner side of the vegetable compartment 420, thereby separating the ozone generator 500 and the vegetable compartment 420.

In addition, the first cover member 510 adjusts the ozone emission amount and emission range into the vegetable compartment 420 of the ozone generator 500 by providing a plurality of suction ports 512 behind the lower surface.

Specifically, on the lower surface of the first cover member 510 of the adjusting member, a storage portion 510a without the release hole 511 is formed near the center, and positioning release holes 511 are arranged on the left and right sides of the storage portion 510a. Therefore, the ozone emitted from the ozone generator 500 is temporarily accumulated in the storage part 510a located in the center vicinity of the 1st cover member 510 which is an adjustment member which does not have the discharge hole 511. As shown in FIG. However, ozone, which is heavier in specific gravity than air, is gradually diffused onto the entire lower surface of the first cover member 510, and is released downward from the left and right discharge holes 511 arranged in the storage part 510a. In addition, since there are a plurality of release holes 511, it can spread over the entire food storage 400.

On the other hand, the suction hole 512 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 first cover member 510 for adjusting the function of the additional function device. . In the case of the present embodiment, since the suction hole 512 is located on the rear side of the storage room in the vicinity of the cool air discharge port 513 described later, cool air in a relatively dry state is sucked in. Therefore, the upper side of the first cover member 510 as the adjustment member, that is, the humidity inside the first cover member 510 can be kept low, and the ozone generation efficiency in the ozone generator 500 is that the lower the humidity, the higher the efficiency, so it can Maintain high ozone generation efficiency. On the basis of introducing these dry cool air, furthermore, in this embodiment, the first cover member 510 as an adjustment member is provided to separate the storage container 421 and the ozone as a storage space that becomes a high-humidity storage space due to the evaporation of water from vegetables. between generating means 500. Thereby, the upper part of the 1st cover member 510, that is, the periphery of the ozone generator 500 can maintain low humidity further, and can maintain the state with high ozone generation efficiency.

In addition, in the case where the ozone generator 500 adopts a structure that generates ozone by applying a high voltage, the ozone generator 500 is provided near the cool air outlet 513 that flows into the cold air from the outside of the storage room in the temperature distribution of the storage room and becomes low temperature, Therefore, the vicinity of the ozone generator 500 becomes low temperature. Thereby, the generation efficiency of ozone can be improved to some extent at low temperature, and therefore ozone can be generated with high efficiency. Therefore, it is possible to generate a necessary amount of ozone while suppressing the power consumption necessary for ozone generation, which not only contributes to energy saving, but also exhibits an effect of maintaining the freshness of ozone.

In addition, the first cover member 510 as an adjustment member for adjusting the function of the additional function device can be based on the ozone generation efficiency of the ozone generator 500, the amount of oxygen flowing into the first cover member 510 from the suction hole 512, and the amount of oxygen from the discharge hole 511. The ozone concentration of the vegetable compartment 420 is adjusted in relation to the amount of ozone that flows out. That is, the adjustment member for adjusting the function of the additional function device can adjust the ozone concentration to a certain extent in consideration of the capacity of the vegetable compartment 420 by determining the total opening area of the discharge holes 511 provided on the adjustment member at the design stage. Specifically, when there are many discharge holes 511 (total opening area is large), the outflow amount of ozone increases, and the ozone concentration in vegetable compartment 420 becomes high. In addition, the inflow of oxygen increases in proportion to the outflow of ozone, so the number of discharge holes 511 is proportional to the ozone concentration of the vegetable compartment 420 within the limit of the capacity of the ozone generator 500 . On the contrary, when there are few discharge holes 511 (total opening area is small), the outflow amount of ozone is small, and the ozone concentration in vegetable compartment 420 is low.

In addition, by studying the installation angle and position of the release hole 511 of the first cover member 510 as an adjustment member, and making the first cover member 510 movable, the release amount and release angle of the functional substance can be further adjusted. Improve the functionality of preserved objects more effectively.

In addition, the adjustment member for adjusting the function of the above-mentioned additional function device flows out ozone and flows in oxygen by natural convection, but it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, by configuring the ozone concentration meter to be able to measure the ozone concentration in the storage container 421, the ozone generation amount of the ozone generator 500 is adjusted according to the information from the ozone concentration meter (for example, the opening and closing of the fan), and the ozone concentration in the storage container 421 is adjusted. The ozone concentration is kept within the specified range.

It is preferable that the ozone concentration in the vegetable room 420 and the storage container 421 which are food storage rooms be maintained at 0.05 ppm or less. This is because when the ozone concentration is high, when pulling out the storage container 421 and taking out food such as vegetables from the storage container 421, there may be any influence on the human body of the user who performs these operations. In addition, it is preferably maintained at 0.03 ppm or less. This is because when the concentration of ozone is high, the odor of ozone will give discomfort to the person who performs the work.

In the present embodiment, the third light source 520 is also provided as the additional function device, so the third light source 520 that irradiates light as the additional function device and the adjusting member that adjusts the light of the third light source 520 will be described.

The third light source 520 has the function of increasing the food stored in the vegetable room 420 serving as a storage room, such as functional ingredients such as vitamin C, which the food has, and promoting the defense reaction of the living body. In the case of this embodiment, LEDs are used as the third light source 520 . LED has low heat generation, can prevent the temperature rise in the storage space, can improve food preservation, low running cost, and has excellent durability, and can realize compact design, so it has high versatility and is suitable as a specification for refrigerators.

In addition, the third light source 520 is arranged above the first cover member 510 as an adjusting member for adjusting the function of the additional function device, and is surrounded by the first cover member 510 . Thus, by separating the storage space in the vegetable compartment 420 from the third light source 520 , it is also possible to prevent the third light source 520 from dew condensation due to the moisture in the vegetable compartment 420 with high humidity, which would cause the predetermined wavelength to be blocked. Absorption, increase efficiency of the functional ingredient worsen.

In this way, the irradiation adjustment part 510 b is also provided in the first cover member 510 as an adjustment member for adjusting the light from the third light source 520 . The irradiation adjustment unit 510b is also provided in the irradiation adjustment unit 510b. The irradiation adjustment unit 510b is made of a material capable of transmitting light having a necessary wavelength among the light emitted from the third light source 520 as a function-added device. For example, epoxy resin, acrylic, polycarbonate, polyethylene, polystyrene, polypropylene, etc. are used as one material of the transparent resin of the translucent resin. Alternatively, a composite material in which a plurality of light-transmitting resins are combined is suitable as a base material because it has diffusivity.

The wavelength emitted by the third light source 520 as an additional function device is set in a predetermined wavelength range that promotes the defense reaction of the food stored in the storage room and can promote the increase of functional components such as vitamin C and polyphenylene ether.

Specifically, the wavelength range of the third light source 520 is preferably a wavelength of 380nm to 800nm, for example, a wavelength in the ultraviolet range of 280nm to 400nm, which is a wavelength that is relatively safe for the human body. It contains a lot of ergosterol, which is a precursor substance of vitamin D, so when these substances are irradiated with the above-mentioned wavelength, the molecules are excited and converted into vitamin D, so the content of vitamin D can be increased and the content can be preserved at the same time, and the nutritional value can be improved. These effects are also the same in the case of fish, especially herring such as mackerel and mackerel. In addition, in fruits and vegetables such as grapes, apples, and strawberries containing anthocyanins, polyphenols can be increased and preserved, and the functional value of the refrigerator can be improved.

In addition, since residual pesticides adhering to vegetables or fruits are irradiated with the third light source 520 containing ultraviolet wavelengths, photodecomposition reaction occurs and toxicity is reduced, so they can be stored more safely.

In addition, in particular, when blue having a peak wavelength around 400 nm to 500 nm is used, it is possible to prevent degradation of synthetic resins widely used in refrigerators, etc., compared with ultraviolet wavelengths. In addition, it can suppress quality deterioration such as lipid oxidation in long-term storage foods, and has an effect of suppressing the growth of bacteria or mold as a unique effect of blue wavelengths. Therefore, it is possible to keep the inside of the cabinet of the refrigerator and the surface of preserved objects or fruits and vegetables clean. In addition, there is also a sensory effect of giving the user a feeling of cleanliness due to the refreshing feeling of blue.

In addition, by using green having a peak wavelength around 500 nm to 600 nm, it is possible to prevent degradation of synthetic resins widely used in refrigerators, etc., compared with ultraviolet wavelengths and the like. Furthermore, since the action light unique to the green wavelength penetrates into the inside of the fruit and vegetable, it can promote the action on the inside of the fruit and vegetable, and the biological defense reaction from the inside side can further increase nutrients such as vitamins.

Thus, when the third light source 520 emits combined blue wavelength and green wavelength light, the blue wavelength light can suppress the growth of fungi on the surface of fruits and vegetables, and the green wavelength penetrating into the fruits and vegetables can also promote the growth of fungi inside the fruits and vegetables. The living defense reaction can further improve the preservation of fruits and vegetables.

In addition, regarding the irradiation method of the third light source 520, the above-mentioned effect can also be obtained by continuous irradiation, but by flashing the third light source 520, the stimulation can be made stronger, so the effect of inhibiting the growth of fungi is enhanced in blue, and in addition, blue Chromatic light can promote living defense reactions on the surface of fruits and vegetables. In the same way, green can further promote the defense of the living body from the inside, so it is an effective irradiation method.

In addition, in this embodiment, an LED is used as the third light source 520 , but it is not particularly limited, and the third light source 520 that emits light of a continuous spectrum may be used. In addition, when a structure in which a plurality of LEDs emitting lights of different wavelengths is combined is used as the third light source 520, a multi-layered effect can be further obtained.

15 is a partial side sectional view of the vegetable compartment of the refrigerator according to Embodiment 3 of the present invention, FIG. 16A is a partial side sectional view of the food container of the refrigerator, and FIG. 16B is a partial side sectional view of the lid of the refrigerator. In addition, in this embodiment, by providing the storage containers 421 inside a plurality of storage rooms, it can be divided into a plurality of storage partitions.

As shown in Fig. 16A and Fig. 16B, in the storage container 421 in the vegetable compartment 420, a lower container 421a as the largest storage partition and an upper container 421b located on the upper part of the lower container 421a are also provided. 421 partitions for storage. The interior of the storage room is divided into a plurality of storage partitions, and the ozone generator 500 as an additional function device and the first cover member 510 as an adjustment member are located above the partition with the largest capacity among the storage partitions. That is, the center of the vegetable room is slightly in front of the vicinity. Thereby, ozone is first diffused in a wide range in the lower container 421a without being blocked by the upper container 421b which is generally a fruit box, and the functionality of stored objects can be improved more effectively.

In addition, the installation position of the 3rd light source 520 is located in this embodiment, and it is positioned on the upper side of the upper container 421b used as a fruit box on the rear side of the vegetable compartment 420. As shown in FIG. In this case, the upper container 421b is made of a translucent material. If it is a light-transmitting material like this, the effect of the container hindering the diffusion is small, and the lower container 421a is irradiated through the upper container 421b, so that the light can be diffused to the entire storage space of the vegetable compartment 420, so it is not necessary to arrange it in a certain place. It is directly above the lower container 421a which is the largest storage section.

In addition, food storage 400 is provided with a not-shown cooling device. In the case of the present embodiment, the cooling device is constituted by a cooling cycle having two coolers. Specifically, a first cooler 142a is provided on the rear side of the inner portion of the refrigerating room 410 . The inner portion of the refrigerator compartment 410 is cooled by heat conduction from the first cooler 412a. The air in the refrigerator compartment 410 is cooled by the cooled inside.

Moreover, the 2nd cooler 412b is provided in the rear side of the back of the freezer compartment 430. As shown in FIG. The inside of the freezer compartment 430 is cooled by the cold air that forcibly passes through the second cooler 412b, and the cold air that cools food etc. returns to the second cooler 412b again.

As shown in FIG. 15 , the cool air discharged from the second cooler 412 b is supplied to the vegetable compartment 420 through the cool air discharge port 513 . Vegetable compartment 420 controls the amount of cold air to be supplied by opening and closing a valve (damper), and maintains a temperature range between the temperature range of refrigerator compartment 410 and the temperature range of freezer compartment 430 . Specifically, it is controlled to maintain the temperature within the range of 4°C or lower and 0°C or higher.

In addition, when the cool air released from the second cooler 412b is supplied to the vegetable compartment 420 through the cool air discharge port 513, the function is effectively added by the action of an additional function device such as an ozone generator. That is, even by killing miscellaneous bacteria with ozone, only the clean cold air can be diffused into the vegetable compartment 420 and the planktonic bacteria in the vegetable compartment 420 can be killed. In addition, the cool air diffused in vegetable compartment 420 is cooled again by second cooler 412b outside freezer compartment 430 through suction port 514 . Therefore, ozone is always circulated in the vegetable compartment 420 and the freezer compartment 430, and it is always a clean space, so food can be stored safely.

The storage container 421 is comprised by the lower container 421a and the upper container 421b, is arrange|positioned in the vegetable compartment 420 which is a storage room, and is the box body which has the opening part in the drawable upper part.

The cover 422 is a plate-shaped member that closes the opening of the storage container 421, has a passage hole 424 and an adjustment hole 425, and functions as a second adjustment member. That is, in addition to the first cover member 510 as the first adjustment member, the cover 422 is provided as the second adjustment member on the inner side of the vegetable compartment 420 as the storage compartment beyond the first adjustment member.

That is, temporarily through the effect of additional functional devices such as an ozone generator, the ozone diffused through the adjustment member is accumulated and filled in the upper part of the cover 422, and then diffused evenly in the food container through the passage hole 424 and the adjustment hole 425. In addition, since the cover 422 is made of a material capable of sufficiently transmitting light of a necessary wavelength among the light emitted from the third light source 520, the effect of the light on food can be sufficiently maintained. In addition, the cover 422 is a component that has the function of adjusting the humidity in the storage container 421. Specifically, the moisture evaporated from the vegetables stored in the storage container 421 is maintained in the storage container 421 to some extent, and at the same time, it is stored in the storage container 421. The humidity in the container 421 is adjusted to such an extent that the moisture does not condense.

In addition, a cooling air path 616 and a fan 617 for circulating cold air in the refrigerator compartment 604 are provided on the back of the refrigerator compartment 604. The cooling air path 616 has a first outlet 618, a second outlet 619, and a third outlet for blowing out cold air. The air outlet 620, the fourth air outlet 621, and the first air inlet 622, the second air inlet 623, and the third air inlet 624 for sucking return air.

In addition, a shelf 626 is provided on the top of the third storage box 615 to roughly block the opening 625 of the third storage box 615. On the shelf 626, an ozone generator 627 and a fourth light source 628 as an additional function device are provided. Second cover part 629 of the adjustment part for adjusting the effect of the additional function 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 condensed in the condenser 605 to form a liquid refrigerant. The refrigerant condensed in the condenser 605 flows to the first decompression device or the second decompression device through the switching valve, and is decompressed to form a low-pressure and low-temperature gas-liquid two-state refrigerant.

Here, the refrigerant flowing to the first decompression device passes through the refrigerating evaporator, evaporates in the freezer compartment 603 , cools the freezer compartment 603 by the heat of evaporation and vaporization, and is sucked into the compressor again.

In addition, the refrigerant flowing to the second decompression device flows from the refrigerating evaporator 609 to the freezing evaporator through the switching valve, and evaporates in the refrigerating room 604 and the freezing room 603, thereby cooling the refrigerating room by utilizing the heat of evaporation and vaporization. 604 and the freezer compartment 603 are sucked into the compressor again.

Here, the cold air obtained by the heat of evaporation and vaporization of the liquid refrigerant in the refrigerating evaporator 609 flows through the cooling air passage 616 by the fan 617, and flows from the first air outlet 618, the second air outlet 619, and the third air outlet. 620 and the fourth outlet 621 to cool each partition.

In addition, the return air that cools the other partitions in the second storage box 614 and the third storage box 615 flows through the inside and outside of the box to be cooled.

In addition, the relatively high-temperature return air sucked from the first suction port 622, the second suction port 623, and the third suction port 624 evaporates the liquid refrigerant in the refrigerating evaporator 609 due to the temperature difference, and deprives heat to form The low temperature is guided in the cabinet by the fan 617 again to cool each partition.

The ozone generator 627 as an additional function device is a device capable of generating ozone to be supplied to the third storage box 615 arranged in the storage room. Ozone generated by the ozone generator 627 has a heavier molecular weight than air, so it tends to stay on the bottom of the third storage box 615, and it is more likely to fill the third storage box 615.

Here, the ozone generator 627 is not particularly limited as long as it generates ozone. Specific examples include a device that irradiates air-heavy oxygen molecules (O ₂ ) with ultraviolet light to generate ozone (O ₃ ), and a device that converts air-heavy oxygen molecules into ozone by discharging or the like using an electrode placed on air-heavy electrodes as a high voltage. , Decomposition of water and other substances containing oxygen, devices that supply ozone to the air, etc.

19 is a sectional view of a storage box including a second cover member of the refrigerator according to Embodiment 4 of the present invention, and FIG. 20 is a sectional view of a first cover member of the refrigerator.

The adjustment part that is used to adjust the effect of additional functional device is to be arranged in the inner side of the storage room of the ozone generator 627 as additional functional device, the second cover part 629 that is made of the thin plate that separates ozone generator 627 and storage room, as As shown in FIG. 20 , it is a second cover member 629 in the shape of an inverted quadrangular truncated pyramid provided with a plurality of discharge holes 631 in front of the lower surface. In this case, the second cover member 629 as an adjustment member has a plurality of discharge holes 631, thereby being able to adjust the amount of ozone emitted from the ozone generator 627 as an additional function device into the third storage box 615 as a storage room. amount of ozone. That is, the amount of ozone flowing into the third storage box 615 is determined by the size and number of the discharge holes 631 . In addition, it is possible to adjust the emission range of ozone generated from the ozone generator 627 into the third storage box 615 by the position where the emission hole 631 is provided. In this way, the second cover member 629 as an adjustment member for adjusting the function of the additional function device is arranged in the third storage box of the ozone generator 627 and the fourth light source 628 as the additional function device embedded in the partition plate 626. The inner side of 615 covers its installation, thereby separating the storage space of the ozone generator 627 and the third storage box 615 .

In addition, the second cover member 629 is provided with a plurality of suction holes 632 behind the lower surface to adjust the emission amount and emission range of ozone into the third storage box 615 of the ozone generator 627 .

Specifically, on the lower surface of the second cover member 629 of the adjustment member, a storage portion 629a without the release hole 631 is formed near the center, and the release hole 631 is positioned on the left and right sides of the storage portion 629a. Therefore, the ozone generated from the ozone generator 627 is temporarily accumulated in the vicinity of the storage part 629a near the center of the second cover member 629, which is an adjustment member that does not have the discharge hole 631, but the ozone with a specific gravity heavier than air gradually diffuses to the second cover member 629. The entire lower surface of the cover member 629 is discharged downward from the discharge holes 631 arranged on the left and right sides of the storage part 629a. In addition, since there are a plurality of discharge holes 631, it is possible to diffuse over the entire food storage 400.

On the other hand, the suction hole 632 arranged on the rear side of the center in the front-rear direction of the storage compartment mainly functions as a ventilation port for sucking cold air from the outside of the second cover member 629 serving as a device for adjusting additional functions. . In the case of Embodiment 4, since the suction hole 632 is located on the rear side of the storage room in the vicinity of the cool air discharge port 513 described later, the cool air in a relatively dry state is sucked in. Therefore, it is possible to maintain the upper side of the second cover member 629 as an adjustment member, that is, the humidity inside the second cover member 629 is relatively low. Since the efficiency of ozone generation in the ozone generator 627 is that the lower the humidity, the better the efficiency. A state where the ozone generation efficiency is high is maintained. In addition to the introduction of these dry air, in Embodiment 4, the second cover member 629 as an adjustment member is also provided to partition the third storage room, which is an indoor space with high humidity due to evaporation of water from vegetables. Between the box 615 and the ozone generator 500, the upper part of the second cover member 629, that is, the periphery of the ozone generator 627 can be further maintained with low humidity, and the ozone generation efficiency can be maintained in a high state.

In addition, when ozone is generated by applying a high voltage to the ozone generator 627, in the temperature distribution in the storage room, since cool air flows in from the outside of the storage room, an ozone generator is placed near the cool air outlet 513 that constitutes a low temperature. 627, so that the vicinity of the ozone generator 627 becomes low temperature, so that the generation efficiency of ozone can be improved to some extent at low temperature, so ozone can be generated with high efficiency. Therefore, it is possible to generate a necessary amount of ozone while suppressing the power consumption necessary for ozone generation, which not only contributes to energy saving, but also exhibits an effect of maintaining the freshness of ozone.

In addition, the second cover member 629 as an adjustment member for adjusting the function of the additional function device can flow out from the discharge hole 631 according to the ozone generation efficiency of the ozone generator 627, the amount of oxygen flowing into the second cover member 629 from the suction hole 632 The ozone concentration in the third storage box 615 is adjusted according to the relationship of the amount of ozone. That is, the adjustment member used to adjust the effect of the additional function device determines the total opening area of the discharge hole 631 provided on the adjustment member at the design stage, thereby considering the capacity of the third storage box 615 and adjusting the ozone to a certain extent. concentration. Specifically, when there are many discharge holes 631 (the total opening area is large), the outflow of ozone increases, and the ozone concentration in the third storage box 615 increases. In addition, since the inflow of oxygen increases proportionally to the outflow of ozone, the number of discharge holes 631 is proportional to the ozone concentration of the third storage box 615 within the limit of the capacity of the ozone generator 627 . On the contrary, when there are few discharge holes 631 (total opening area is small), the outflow amount of ozone decreases, and the ozone concentration in the third storage box 615 decreases.

In addition, by studying the installation angle and position of the release hole 631 of the second cover member 629 as an adjustment member, and making the second cover member 629 movable, the release amount and release angle of the functional substance can be further adjusted. Improve the functionality of preserved objects more effectively.

In addition, the adjustment member for adjusting the function of the above-mentioned additional function device flows out ozone and flows in oxygen by natural convection, but it is also possible to use a fan to forcibly flow out ozone and take in oxygen. In addition, by disposing an ozone concentration meter to be able to measure the ozone concentration in the third storage box 615, and adjusting the ozone generation amount of the ozone generator 627 (for example, turning on and off the fan) according to the information from the ozone concentration meter, the third storage box The ozone concentration in the tank 615 is maintained within a specified range.

The ozone concentration in the third storage box 615 is preferably maintained at 0.05 ppm or less. This is because there is concern that when the ozone concentration is high, it will have any effect on the human body performing these operations when taking out foods such as vegetables. In addition, it is preferably maintained at 0.03 ppm or less. This is because when the concentration of ozone is high, the odor of ozone will give discomfort to the people who perform the work. However, the ozone concentration is not limited.

In Embodiment 4, since the fourth light source 628 is also provided as the additional function device, the fourth light source 628 for irradiating light as the additional function device and the adjusting member for adjusting the light of the fourth light source 628 will be described next. .

The fourth light source 628 has the function of promoting the biological defense reaction of the food stored in the third storage box 615 as a storage room, such as functional ingredients such as vitamin C, which the food has. In the case of Embodiment 4, LEDs are used as the fourth light source 628 . LEDs have low calorific value, can prevent temperature rise in the storage space, can stabilize food preservation, have low operating costs, are excellent in durability, and can be compactly designed, so they have high versatility and are preferred as specifications for refrigerators.

In addition, the fourth light source 628 is disposed above the second cover member 629 as an adjusting member for adjusting the action of the additional function device, and is surrounded by the second cover member 629 . Thus, by separating the indoor space in the third storage box 615 from the fourth light source 628, it is possible to prevent the fourth light source 628 from dew condensation and absorbing a predetermined wavelength due to moisture in the third storage box 615 with high humidity. The light makes the increase efficiency of functional ingredients worse.

In this manner, the second cover member 629 is provided with an irradiation adjustment portion 629 b as an adjustment member for adjusting light from the fourth light source 628 . The irradiation adjustment unit 629b is preferably made of a material capable of transmitting light of a necessary wavelength among the light emitted by the fourth light source 628 as an additional function device. For example, epoxy resin, acrylic, polycarbonate, polyethylene, polystyrene, polypropylene, etc. are used as one material of the transparent resin of the translucent resin. Alternatively, a composite material in which a plurality of light-transmitting resins are combined is suitable as a base material because it has diffusivity.

The wavelength emitted by the fourth light source 628 as an additional function device is set in a predetermined wavelength region that promotes the defense reaction of the living body to the food stored in the storage room and can promote the increase of functional components such as vitamin C and polyphenylene ether.

Specifically, the wavelength range of the fourth light source 628 is preferably a wavelength of 380nm to 800nm, for example, a wavelength in the ultraviolet range of 280nm to 400nm, which is a wavelength that is relatively safe for the human body. It contains a lot of ergosterol, which is a precursor substance of vitamin D, so when these substances are irradiated with the above-mentioned wavelength, the molecules are excited and converted into vitamin D, so the content of vitamin D can be increased and the content can be preserved at the same time, and the nutritional value can be improved. These effects are also the same in the case of fish, especially herring such as mackerel and mackerel. In addition, in fruits and vegetables such as grapes, apples, and strawberries containing anthocyanins, polyphenols can be increased and preserved, and the functional value of the refrigerator can be improved.

In addition, since residual pesticides adhering to vegetables and fruits are irradiated with light of wavelengths including ultraviolet rays, photodecomposition reactions occur and toxicity is reduced, so they can be stored more safely.

In addition, in particular, when blue having a peak wavelength around 400 nm to 500 nm is used, it is possible to prevent degradation of synthetic resins widely used in refrigerators, etc., compared with ultraviolet wavelengths. In addition, it can suppress quality deterioration such as lipid oxidation in long-term storage foods, and has an effect of suppressing the growth of bacteria or mold as a unique effect of blue wavelengths. Therefore, it is possible to keep the inside of the cabinet of the refrigerator and the surface of preserved objects or fruits and vegetables clean. In addition, there is also a sensory effect of giving the user a feeling of cleanliness due to the refreshing feeling of blue.

In addition, by using green having a peak wavelength around 500 to 600 nm, it is possible to prevent deterioration of synthetic resins widely used in refrigerators, etc., compared with ultraviolet wavelengths and the like. Furthermore, since the action light unique to the green wavelength penetrates into the inside of the fruit and vegetable, it can promote the action on the inside of the fruit and vegetable, and the biological defense reaction from the inside side can further increase nutrients such as vitamins.

Thus, when the fourth light source 628 emits combined blue wavelength and green wavelength light, the blue wavelength light can suppress the growth of fungi on the surface of fruits and vegetables, and the green wavelength penetrating into the fruits and vegetables can also promote the growth of fungi inside the fruits and vegetables. The living defense reaction can further improve the preservation of fruits and vegetables.

In addition, regarding the irradiation method of the above-mentioned light, the above-mentioned effect can also be obtained by continuous irradiation, but the stimulation can be made stronger by flashing irradiation, so the effect of inhibiting the growth of bacteria in blue is enhanced, and in addition, the blue light can promote the growth of the surface of fruits and vegetables. in vivo defense responses. In the same way, green can further promote the defense of the living body from the inside, so it is an effective irradiation method.

In addition, in this embodiment, an LED is used as the fourth light source 628 , but it is not particularly limited, and the fourth light source 628 that emits light of a continuous spectrum may be used. In addition, when a structure in which a plurality of LEDs emitting lights of different wavelengths is combined is used as the fourth light source 628, a multi-layered effect can be further obtained.

In this way, in Embodiment 4, with respect to the adjustment member disposed so as to cover the ozone generator 627 and the fourth light source 628 as the additional function device, for example, ozone gas generated from the additional function device is not immediately transferred to the The storage compartment is released, but after passing through a plurality of adjustment parts. As a result, the released amount and released range can be adjusted more precisely, and the functionality of stored items inside the storage compartment can be more effectively improved.

In addition, the additional function device adopts an ozone generating device and an LED, but it may also be an ultrasonic generator, and may also be various devices capable of additional functions such as a mist generating device that sprays mist.

(Embodiment 5)

Fig. 21 is a perspective view of a refrigerator according to Embodiment 5 of the present invention, and Fig. 22 is a side sectional view of the refrigerator.

As shown in Fig. 21 and Fig. 22, the refrigerator of the present embodiment divides the interior into a freezer compartment 703 and a refrigerator compartment 704 as storage compartments by a freezer interior box 701 and a refrigerator interior box 702, and has a storage compressor ( not shown) and a mechanical 706 refrigerator main body 707 of the condenser 705, and a freezer door (not shown) rotatably provided on the front opening of the freezer 703 as a revolving door, and an opening and closing The refrigerator compartment door 708 is freely provided in the front opening of the refrigerator compartment 704 .

In addition, the refrigerator main body 707 has a refrigerating cycle for generating cold air for cooling each storage compartment, and the refrigerating cycle includes a compressor (not shown) in a mechanical unit 706 provided on the lower back, a condenser 705, and a switching valve (not shown). The decompression device, the refrigerating evaporator, and the refrigerating evaporator composed of the first decompression device and the second decompression device are provided with a refrigerant such as hydrocarbon gas with a small environmental load inside, and are connected in a ring shape.

In addition, the condenser for freezing is accommodated in the freezing and cooling compartment, and the condenser for refrigerating is accommodated in the refrigerating and cooling compartment 730 .

A first shelf 710, a second shelf 711, a third shelf 712, a first storage box 713, a second storage box 714, and a third storage box 715 are arranged inside the refrigerator compartment 704, and the interior of the refrigerator compartment 704 is divided into Seven partitions.

In addition, a refrigeration cooling air duct 716 and a fan 717 for circulating cold air in the refrigerator compartment 704 are provided on the back of the refrigerator compartment 704, and the refrigeration cooling air duct 716 is provided with a first outlet 718 and a second outlet 719 for blowing out cold air. , the third outlet 720 and the fourth outlet 721 , the first inlet 722 , the second inlet 723 , and the third inlet 724 for sucking in return air.

Moreover, the partition plate 726 is provided in the upper part of the 3rd storage box 715 so that the opening part 725 of the 3rd storage box 715 may be substantially closed, and the ozone generator 727 is provided in the partition plate 726.

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

When the operation of the refrigerator starts, the high-temperature and high-pressure refrigerant compressed by the compressor is cooled and condensed by heat exchange in the condenser 705 to form a liquid refrigerant. The refrigerant condensed in the condenser 705 flows to the first decompression device or the second decompression device through the switching valve and is decompressed to form a low-pressure and low-temperature gas-liquid two-state refrigerant.

Here, the refrigerant flowing to the first decompression device flows through the refrigerating evaporator, evaporates in the freezer compartment 703, and evaporates in the refrigerator compartment 704 and the freezer compartment 703 by the heat of evaporation and vaporization, thereby utilizing the heat of evaporation and vaporization The inside of the refrigerator compartment 704 and the freezer compartment 703 is cooled, and is sucked into the compressor again.

In addition, the refrigerant flowing to the second decompression device through the switching valve flows from the refrigerating evaporator 709 to the freezing evaporator, cools the refrigerating chamber 704 and the freezing chamber 703, and is sucked into the compressor again.

Here, the cold air obtained by the heat of evaporation and vaporization of the liquid refrigerant in the refrigerating evaporator 709 flows through the cooling air passage 716 by the fan 717, and flows from the first air outlet 718, the second air outlet 719, and the third air outlet. 720 and the fourth blowing port 721 to cool each partition.

In addition, the inside of the second storage box 714 and the third storage box 715 are cooled by the return air that cools each of the other partitions through the inside and outside of the box.

In addition, the relatively high-temperature return air sucked in from the first suction port 722, the second suction port 723, and the third suction port 724 and circulated in the storage compartment evaporates the liquid refrigerant in the refrigerating evaporator 709 due to the temperature difference, And the heat is taken away to form a low temperature, which is guided into the cabinet by the fan 717 again to cool each partition.

In this way, the storage compartment inside the refrigerator is cooled by low-temperature cold air, and the same applies to the adjacent freezer compartment 703 .

Generally, in the storage room of the refrigerator, the refrigerating room 704 maintained at a temperature higher than that of the freezing room 703 is lowered due to the antibacterial of the refrigerating room and the antibacterial preservation of food in the refrigerating temperature zone. An ozone generating device 727 for generating ozone is installed in 704, so that the antibacterial preservation of the storage room and the antibacterial preservation of food in the refrigerated temperature zone can be realized more reliably.

In addition, specifically, an ozone generator 727 is provided in the lowermost storage subregion in the refrigerating room 704, so that the ozone concentration in the third storage container as the lowermost storage subregion can be made the highest, so that even the entry and exit of food Even when the ozone is caused to flow out of the refrigerator, high-concentration ozone can be quickly caused to flow downward, and a safer refrigerator can be improved.

In addition, in this embodiment, the cold air cooled in the refrigerator compartment 704 returns to the refrigerating evaporator 709, and the cold air cooled in the freezer compartment 703 returns to the freezing evaporator, so the cold air cooled in the evaporator returns to the storage room. There are multiple cooling air passages for refrigeration and freezing. In other words, the refrigeration cooling air duct through which the cold air cooled by the refrigerating evaporator flows and the freezing cooling air duct through which the cold air cooled by the freezing evaporator flows are independent refrigerators.

Thereby, the refrigerating and cooling air passage that is easy to multiply by miscellaneous bacteria is separated from the refrigerating and cooling air passage, so that the reduction of the antibacterial function of the refrigerating and cooling air passage can be prevented, and the refrigerating and cooling air passage that is more prone to miscellaneous bacteria can be concentrated and antibacterial by ozone, It is possible to more reliably achieve antibacterial preservation in storage rooms in the refrigerated temperature zone and antibacterial preservation of food, as well as reduce harmful substances such as pesticides adhering to food, and further improve food safety.

In addition, in the refrigerator of the present embodiment, the cold air cooled in the refrigerator-cooling chamber 730 that accommodates the refrigerating evaporator 709 provided separately from the refrigerator chamber 704 passes through the refrigerator-cooling air passage and flows to the refrigerator temperature zone through each outlet in the refrigerator chamber 704. The pantry flows into the cold storage.

Thus, the cold air flowing into the storage room circulates in all the air passages, so an ozone generating device can be installed on one of the refrigeration and cooling air passages, so that the bacteria can be concentrated in the refrigeration and cooling air passages where bacteria are easy to breed, and antibacterial can be concentrated by ozone, and , It is possible to more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigeration temperature zone and the antibacterial preservation of food, and reduce the harmful substances such as pesticides adhering to the food, and further improve the safety of food.

In this way, the present embodiment is a refrigerator in which an ozone generator is installed in the storage section provided with the third storage container located on the most downstream side of the refrigeration cooling air passage in the refrigerator compartment 704 which is a refrigerator temperature zone storage room.

As a result, since the cold air containing bacteria in each storage area flows into the storage area located on the most downstream side in the refrigeration cooling air passage, even though it is an environment where bacteria are easily multiplied in general, antibacterial can be realized concentratedly by ozone, which can be more reliable. The antibacterial of the storage room based on the refrigerated temperature zone and the improvement of the antibacterial preservation of food, as well as the reduction of harmful substances such as pesticides adhering to the food can further improve the safety of food.

In addition, when the third storage container is used as a storage space set to be used as a vegetable room, according to the configuration of the present embodiment, an ozone generator can be installed in the storage room or storage compartment with the highest temperature among the storage rooms in the refrigerating temperature range.

As a result, the temperature is higher, so even though it is an environment that is easy to breed miscellaneous bacteria, it can also be concentrated to realize antibacterial by ozone, and can more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigerated temperature zone and the antibacterial preservation of food, and reduce Harmful substances such as pesticides attached to food can further improve food safety. When applied to vegetable rooms, ozone can reduce harmful substances such as pesticides adhering to food, and can further improve food safety.

The outer case 856 is arranged on the outer side of the inner case 857 to cover the inner case 857 at a predetermined distance from the inner case 857 . The inside of the partition wall 853 is also provided with a gap communicating with the gap between the outer case 856 and the inner case 857 . The gap provided between the outer case 856 and the inner case 857 or the gap of the partition wall 853 is filled with foam such as rigid urethane foam as a heat insulating material. The case main body 850 is manufactured from the above.

Therefore, in this embodiment, the adjacent walls of the first box body 851 and the second box body 852 are inseparable, and the first box body 851 and the second box body 852 share a partition wall 853 as a wall portion.

Fig. 25 is a perspective view showing the lower portion of the first cabinet of the refrigerator according to Embodiment 6 of the present invention.

As shown in FIG. 24 and FIG. 25 , the first box body 851 has a plate body 872 and a drawer 870 located below it. In addition, a second drawer 817 is also provided above the plate body 872 .

The plate body 872 is a plate-shaped member that partitions the inside of the first box body 851 that is a part of the box body 850 in the vertical direction, closes the upper opening of the drawer 870, and blocks the flow of cold air that exists above the plate body 872. Components that flow directly into the inside of the drawer 870 .

Fig. 26 is a perspective view showing a plate body disassembled together with a drawer of the refrigerator according to Embodiment 6 of the present invention.

In the present embodiment, the plate body 872 is composed of a plate main body 878 , a cover body 871 , and a baffle plate 876 . In addition, an ozone generator 873 is attached to the plate body 872 through a casing 874 . The light emitting device 875 is accommodated in the casing 874 .

The board main body 878 is installed on both side walls of the first box body 851 in a bridging shape, and is a component that fixedly divides the upper space and the lower space of the first box body 851 . In addition, a mounting hole 877 is provided at the center of the plate body 872 .

The mounting hole 877 is a hole penetrating the plate main body 878 in the vertical direction, and is used for inserting the housing 874 housing the ozone generator 873 from above.

In this way, by providing the mounting hole 877 in the plate main body 878, it is possible to arbitrarily select whether to mount the ozone generator 873 and the housing 874 or not. Therefore, the variation as refrigerator 800 can be expanded, and when ozone generator 873 and housing 874 are not attached, useless protrusions can be eliminated in the upper space of drawer 870 .

The cover body 871 is a member that closes the mounting hole 877 . In the case of the present embodiment, the cover body 871 is a plate-shaped member arranged over the entire width direction of the plate body 872 . When the ozone generator 873 and the housing 874 are attached to the mounting hole 877 , the lid body 871 covers the mounting hole 877 and closes the opening of the housing 874 . Thereby, even if the upper part of housing|casing 874 is open, it can prevent that the hand of the user of refrigerator 800 will not reach ozone generator 873 easily. In addition, when the ozone generator 873 and the housing 874 are not installed on the installation hole 877, the cover body 871 closes the installation hole 877 to block the passage of cold air and prevent storage items from falling from the installation hole 877. In addition, since the cover body 871 having a flat upper surface occupies most of the plate body 872, the function as the plate body 872 can be ensured, and the design property can be improved at the same time.

The baffle plate 876 is a movable member provided on the front portion of the plate body 872 over the entire width direction. The flapper 876 is a member that jumps up and turns at the front when the drawer 870 is pulled out, and is installed so that storage items can be put in and taken out easily even when the drawer 870 is slightly pulled out. In addition, the baffle 876 is formed of transparent resin, and the goods stored in the drawer 870 can be seen from above the drawer 870 .

The drawer 870 is a box-shaped member whose upper opening is closed by the plate body 872 while being inserted into the space below the plate body 872 , and is freely inserted into and detached from the box body 850 . Since the drawer 870 blocks the inflow of cold air from above by the plate body 872 , the items stored in the drawer 870 do not directly hit the cold air circulating inside the first box body 851 . In addition, the humidity inside the drawer 870 can also be maintained. Therefore, the drawer 870 is suitable for storing vegetables and fruits in a raw state, and is also called a vegetable compartment. In the case of the present embodiment, drawer 870 is formed of transparent (translucent) resin. This is to improve the visibility of the items stored in the drawer 870 , and even when the drawer 870 is inserted into the space below the plate body 872 , the light from the light emitting device 875 can be recognized from the outside of the drawer 870 .

The ozone generator 873 is a device that generates ozone to be supplied to the space below the plate body 872 . In the case of this embodiment, the ozone generator 873 supplies ozone to the inside of the drawer 870 . The ozone generator 873 is installed under the plate body 872 via a housing 874 directly installed on the plate body 872 . The ozone generator 873 has a voltage booster (not shown) that raises the supplied power supply voltage, and an ozone generator (not shown) that generates ozone from oxygen in the air and a high-potential terminal disposed in space. In addition, the ozone generator 873 is not limited to the above. Specific examples include a device that irradiates air-heavy oxygen molecules (O ₂ ) with ultraviolet light to generate ozone (O ₃ ), and a device that converts air-heavy oxygen molecules into ozone by discharging or the like using an electrode placed on air-heavy electrodes as a high voltage. , Decomposition of water and other substances containing oxygen, devices that supply ozone to the air, etc.

The housing 874 is a box-shaped member that accommodates the ozone generator 873 inside and prevents the ozone generator 873 from being easily indirectly touched by hands or stored items. Thereby, the safety of refrigerator 800 can be improved. In addition, the casing 874 is used to suppress the outflow of heat emitted from the ozone generator 873, prevent the space below the plate body 872 from being heated by the ozone generator 873, and maintain the temperature around the ozone generator 873 at a higher temperature. The component which realizes the improvement of the generation efficiency of the ozone. Therefore, power consumption necessary for ozone generation can be suppressed, and energy saving can be contributed.

Fig. 27 is a perspective view showing a cross section of a part of the first cabinet of the refrigerator according to Embodiment 6 of the present invention. The casing 874 is attached in a state of hanging down from the plate 872 , and the housed ozone generator 873 is arranged below the plate 872 . In the case of the present embodiment, a leakage hole 879 through which ozone leaks to the outside of the housing 874 is provided in the lower portion of the housing 874 . Therefore, since ozone leaks from the lower part of the casing 874 protrudingly disposed above the drawer 870 , ozone having a specific gravity higher than air is directly supplied to the inside of the drawer 870 .

From the above, strong convection does not occur inside the drawer 870 where the cool air that has not convected in the first housing 851 directly flows into it. In addition, ozone is directly supplied to the inside of the drawer 870 from the ozone generator 873 arranged above the drawer 870 . Therefore, highly active ozone can exist at a desired concentration inside the drawer 870 . The ozone can efficiently decompose the pesticide remaining on the vegetables, fruits, etc. stored inside the drawer 870 . In addition, ethylene gas released naturally from vegetables and the like can be decomposed to prevent deterioration of vegetables caused by ethylene gas.

Examples of pesticides to be decomposed by ozone include pesticides such as chlorpyrifos, malathion, or quinaphos. These pesticides are used in large quantities in food and have a high possibility of remaining in food.

In addition, in this embodiment, the plate body 872 and the housing 874 are described as separable, but the present invention is not limited thereto. Fig. 28 is a perspective view illustrating another mode of the panel body and the casing of the refrigerator according to Embodiment 6 of the present invention by disassembling. As shown in FIG. 28 , the casing 874 may be integrally formed with the panel main body 878 so that a part of the panel main body 878 bulges downward and the upper part opens. In addition, the cover body 871 may close only the opening of the casing 874 integrated with the board main body 878 .

In addition, the plate body 872 is not limited to integrally partitioning the inside of the box main body 850 from one side to the other.

The light emitting device 875 is a device that irradiates light to the space below the plate body 872 and is accommodated in the housing 874 . The portion of the housing 874 where the light emitting device 875 is mounted is formed so as to transmit the light emitted from the light emitting device 875 , forming a transmission portion. In the case of this embodiment, the light emitting device 875 includes a light emitting diode (LED) as a light source.

The wavelength of light irradiated from the light emitting device 875 is not particularly limited in the present invention. For example, when it is desired to irradiate the vegetables and fruits stored in the drawer 870 with light to increase the content of vitamins, the wavelength of the light irradiated from the light emitting device 875 is preferably visible light between green and blue. When light emitting diodes are used as light sources, light emitting diodes that generate light of the same wavelength may be used, or a plurality of light emitting diodes that generate light of different wavelengths may be used. In addition, the method of emitting light from the light emitting device 875 may be continuous irradiation of light or intermittent irradiation of light. In addition, when light is irradiated intermittently, light may be irradiated intermittently at a high speed or higher than the level at which a human perceives continuous light emission.

On the other hand, in order to promote the decomposition of pesticides such as vegetables and fruits remaining in the drawer 870 or ethylene released from vegetables and the like by ozonation, it is preferable to irradiate light with a wavelength that affects intermolecular vibration between these pesticides and ethylene or ozone. Such wavelengths are also included in any of the infrared region, visible region, and ultraviolet region, but the infrared region is particularly preferable.

Specifically, a wavelength that resonates with the vibration of molecules constituting the pesticide is preferable. This wavelength is considered to exist in the infrared region. More specifically, it is preferable to use the infrared absorption spectrum of the target pesticide, the wavelength of the strongest absorption part, etc. corresponding to the valley part of the spectrum. For example, wavelengths determined from infrared absorption spectra of pesticides such as chlorpyrifos or malathion or quinafos are preferable. This is because these pesticides are used in large quantities in foods and have a high possibility of remaining in foods.

On the other hand, it may be a wavelength for ozone activation. For example, it is a wavelength in the infrared region that ozone absorbs. This is because when ozone is activated, the decomposition of the pesticide can be accelerated.

In addition, in this embodiment, a light emitting diode is used as a light source, but it is not particularly limited thereto, and may emit light with a continuous spectrum. In addition, multiple light sources may be irradiated with wavelengths for different purposes such as vitamin enhancement and pesticide decomposition.

Fig. 29 is a perspective view showing a rear panel of the refrigerator according to Embodiment 6 of the present invention.

As shown in this FIG. 29 and FIG. 27 , in the present embodiment, refrigerator 800 has rear panel 830 . The back panel 830 is arranged on the back of the inserted drawer 870, and separates an evaporator (not shown) constituting the cooling cycle of the refrigerator 800 from the inner space of the first box 851, and has a cool air discharge port and suction point. The rear panel 830 has a rear panel main body 831 and a rear trim panel 832 .

The back panel body 831 is a heat insulating member, and keeps the inside of the first box 851 at an appropriate temperature by separating the evaporator disposed on the back of the back panel body 831 from the inside of the first box 851 .

The rear decorative plate 832 is for improving the designability of the inner surface of the first housing 851 , and is attached to the rear decorative plate 832 so as to cover the entire front surface of the rear panel main body 831 .

In addition, a third cover member 866 that covers the second light emitting device 865 and the second light emitting device 865 is attached to the rear surface decoration plate 832 .

The second light-emitting device 865 has the same function as the light-emitting device 875, and by irradiating light from multiple directions with the light-emitting device 875, it is possible to reduce the shadow of the storage inside the drawer 870, and maintain the improvement of vitamins and the decomposition of pesticides. A device that promotes the effect.

As described above, refrigerator 800 according to the present embodiment is provided with ozone generator 873 hanging below plate body 872 . In addition, in a state where the drawer 870 is inserted, the plate body 872 closes the upper opening of the drawer 870 . Therefore, the ozone generator 873 is arranged in the space closed by the plate body 872 and the drawer 870, and supplies ozone directly to the space. Therefore, there is a relatively high concentration of ozone inside the drawer 870, and the space is isolated from the convection that occurs inside the first box 851, so the ozone stays inside the drawer 870 for a long time. Accordingly, chemical substances such as agricultural chemicals and ethylene gas present inside the drawer 870 can be efficiently decomposed, and sterilization and fungal growth can be efficiently performed.

In addition, the light from the light emitting device 875 or the second light emitting device 865 can also promote the decomposition and sterilization of chemical substances, and can also increase the vitamin content of vegetables and fruits stored inside the drawer 870 .

In addition, in this embodiment, although there is a drawer 870 in the space below the plate body 872, the drawer 870 is not necessary. For example, a door that can only be compared to the space below the plate body 872 can be provided. Store items directly.

(Embodiment 7)

Fig. 30 is a side sectional view of the refrigerator according to Embodiment 7 of the present invention.

In FIG. 30 , a refrigerator 900 is partitioned from above by a partition plate 901 into a refrigerator compartment 902 , a vegetable compartment 903 , and a freezer compartment 904 .

In addition, in order to cool the refrigerator 900, the refrigerating cycle is composed of a compressor, a condenser, a pressure reducing device (not shown) such as an expansion valve or a capillary tube, a cooler 905, piping for connecting these components, a refrigerant, and the like. The cold air generated in the circulation cools the store room of the refrigerator 900 .

In addition, the refrigerator 900 has a fan 906 for sending the cold air cooled by the cooler 905 to each storage room space, and a cooling air path 907 for sending the cold air blown by the fan 906 to each storage room space. Each storage room and the partition board 901 are insulated from heat.

In addition, on the cooling air passage 907, between the cooler 905 and the refrigerating room 902, a refrigerating room shutter 908 is provided, between the cooler 905 and the vegetable room 903, between the vegetable room 909, the cooler 905 and the refrigerating room A freezer shutter 910 is provided between them.

The refrigerator compartment 902 is configured so that the set temperature is maintained at 3°C, the vegetable compartment 903 is maintained at 5°C, and the freezer compartment 904 is maintained at -18°C. Here, the refrigerating compartment shutter 908, the vegetable compartment shutter 909, and the freezing compartment shutter 910 are controlled to open when the cold air cooled by the cooler 905 is sent into each storage room by the fan 906 in order to maintain the set temperature of each storage room. close.

In addition, the vegetable compartment 903 may become below 0 degreeC by being cooled by contacting the freezer compartment 904 maintained at -18 degreeC below it. Therefore, a vegetable compartment heater 911 is provided under the vegetable compartment 903 as means for maintaining the vegetable compartment 903 at 5° C. to heat the underside of the vegetable compartment 903 .

In addition, although frost adheres to cooler 905 due to moisture generated from food stored in refrigerator 900 , defrosting heater 912 for melting the frost is provided below cooler 905 . In order to prevent that when the thawing heater 912 operates, the air heated by the thawing heater 912 flows into the refrigerator compartment 902, the vegetable compartment 903 and the freezer compartment 904 to increase the temperature of each storage compartment. And the freezer shutter 910 is controlled in a closed state to prevent the temperature from rising.

In addition, the vegetable compartment 903 is provided with an ozone generator 1010 for generating ozone for decomposing and removing harmful substances such as agricultural chemicals adhering to the surfaces of vegetables and fruits stored in the vegetable compartment 903 by oxidative decomposition. In addition, the fifth light source 1021 is an activation promoting device that promotes the decomposition of harmful substances such as agricultural chemicals in this embodiment, and emits a predetermined wavelength that activates the biological defense reaction of fruits and vegetables stored in the vegetable compartment 903 as a storage compartment. Light-emitting diodes (LEDs). The activated fruits and vegetables have increased vitamins as antioxidant substances, and at the same time as the decomposition of harmful substances such as pesticides by ozone, the vitamins increased in fruits and vegetables decompose harmful substances such as pesticides attached to the surface of fruits and vegetables. Thereby, the decomposition of pesticides by ozone can be accelerated. In addition, the ozone adsorption filter 1022 as an ozone reduction device that reduces the amount of ozone after decomposing harmful substances attached to the surfaces of vegetables and fruits by ozone, and after reducing the amount of harmful substances adhering to the surfaces of vegetables and fruits decomposed by ozone A spraying device 1023 serving as a decomposed substance reducing device for generated decomposed substances is also installed on the vegetable compartment 903 .

About the food storage comprised as mentioned above, the operation|movement and effect|action are demonstrated below.

First, ozone is generated from the ozone generator 1010 provided in the vegetable compartment 903, and the vegetable compartment 903 in which vegetables and fruits are stored is filled. The full ozone contacts 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, decomposing into harmless safe substances.

Here, utilizing the decomposition and removal of the ozone generated from the ozone generator 1010, the high-concentration oxidative decomposition is carried out as soon as possible for oxidative decomposition. As a result, these harmful substances can be efficiently decomposed. It has bad effects, and you may worry about its smell being noticed, so try to use a low concentration. Therefore, in order to keep the vegetable compartment 903 at an ozone concentration that does not have a bad influence on the human body and the smell of ozone is not felt, that is, an ozone concentration below 0.03 ppm, the ozone generator 1010 repeatedly stops operation, and the operation rate is controlled at 17%. , control the ozone concentration does not rise more than 0.03ppm. On the other hand, when the vegetable compartment 903 is cooled, the cooled cold air passes through the cooling air passage 907 by the fan 906, is blown toward the vegetable compartment 903, and flows out. Therefore, the ozone filling the vegetable compartment 903 enters an environment where it is easy to diffuse from the vegetable compartment 903 along with the air blown during cooling and the cold air flowing out. Therefore, during the cooling of the vegetable compartment 903, the operating rate of the ozone generator 1010 is controlled to 45%, and the operating rate of the ozone generating device 1010 is increased to compensate for the ozone lost from the vegetable compartment 903 by diffusion. Thereafter, when the cooling of the vegetable compartment 903 was stopped, the ozone generator 1010 supplied ozone to the vegetable compartment 903 again at an operation rate of 17%.

Like this, under the situation that cold air flows into vegetable compartment 903, ozone generator 1010 increases the supply amount of ozone with 45% operating rate, under the situation that does not flow into cold air, ozone generator 1010 is operated with 17% operating rate, thereby even The cooled cold air is diffused from the vegetable compartment 903 by the fan 906, and by increasing the operating rate of the ozone generator 1010, it can also be efficiently and reliably sent to the vegetable compartment 903 to decompose and adhere to the surface of the vegetables stored in the storage compartment. A small amount of ozone at 0.03ppm is aimed at the residual pesticides and other harmful substances.

That is, the ozone generating device 1010 that the vegetable room has can be low-power, can realize more resource-saving, the ozone concentration that energy-conservation effect is played, and even in case ozone flows out to the storage room, because it is a relatively small amount of ozone Therefore, it can be said that it is a structure that takes the safety of users into consideration.

In addition, an ozone concentration sensor may be attached to the vegetable compartment 903 so that the ozone concentration does not increase, and the ozone generator 1010 may be controlled so that the ozone concentration in the vegetable compartment 903 becomes 0.03 ppm or less.

In addition, the fifth light source 1021 as an activation accelerator is an LED element, but in order to efficiently activate the biological defense reaction of fruits and vegetables, blue light with a center wavelength of 470 nm is used as a wavelength for allowing light to permeate the surface of fruits and vegetables. It is preferable to use green light with a central wavelength of 520 nm as the wavelength of light directed toward the interior of fruits and vegetables. At this time, the irradiation intensity from the fifth light source 1021 having the blue LED and the green LED that irradiates the object (fruit and vegetable) is in the range of 5 lx to 500 lx.

With regard to the irradiation intensity, when the irradiation intensity is less than 5 lx, it is difficult to increase the vitamin as an antioxidant substance which increases the defense reaction of the living body under light irradiation. In addition, if the irradiation intensity is less than 5 lx, it is difficult for the user to recognize the brightness of the lighting when opening and closing the door, so it is actually difficult to obtain the effect promotion of the product when it is placed on the refrigerator. demands.

On the other hand, if it exceeds 500lx, the light intensity will be too strong, and the water evaporation of fruits and vegetables will be promoted on the contrary, and the freshness may be reduced. In addition, depending on the situation, the irradiated light may be bent or discolored, and the functional quality may deteriorate. Also, when the amount of light increases when the door is opened and closed, it tends to be difficult for the user as a consumer to enjoy the refreshing feeling as a refrigerator.

In view of this, as the light quantity of the fifth light source 1021, the brightness range of 20lx-100lx can realize the increase of vitamins as antioxidant substances on the functional level, and is an effective range that does not promote the evaporation of water from fruits and vegetables, and is sensory. When opening and closing, the user can experience the functional effect of the light irradiation from the fifth light source 1021, and the brightness range that embraces a refreshing feeling is more preferable.

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

In addition, in an actual product, when checking the intensity of the irradiation ratio, the intensity of the brightness of the indoor space itself can be confirmed with a luminance meter. Specifically, also in the case of two-color irradiation, switching the control board etc. to irradiate each color and measuring the respective luminances can confirm the intensity of each wavelength, that is, the luminance of each color.

This is because green light has a wavelength that has no side effects on fruits and vegetables. Therefore, in order to increase the amount of vitamins in fruits and vegetables as an antioxidant substance and increase the intensity of green light penetrating into fruits and vegetables, the quality of fruits and vegetables will not be reduced. , can increase the amount of vitamins, so it is effective. According to experiments, it is found that the brightness of the green light is set to be 3 to 10 times that of the blue light, which is effective. That is, at a level of less than 3 times, the effect of increasing the amount of vitamins inside fruits and vegetables is insufficient, and at a level of more than 10 times, it is difficult to expect the effect of increasing the amount of vitamins on the surface of fruits and vegetables, and it is difficult to obtain a comprehensive result in either case. The effect of increasing the amount of vitamins.

In addition, the intermittent irradiation of fruits and vegetables can stimulate the vegetables more than the continuous lighting irradiation. In addition to photosynthesis to generate vitamin C, it can also promote the generation of vitamin C as an antioxidant in the defense reaction of vegetables, which can further promote the harmful effects of pesticides and other harmful substances. substance removal. Therefore, the fifth light source 1021 is preferably controlled to flash and irradiate (intermittently irradiate) the green LED and the blue LED simultaneously at any frequency in the range of 20-50 Hz around 40 Hz.

This causes a problem that, in the case where the slow flickering of 20 Hz or less can be clearly recognized by the user as flickering of intermittent illumination, the flickering of the light feels a warning such as notifying any abnormality, or a sense of psychological pressure is felt when the flickering continues to be sluggish. , or angry emotions such as irritability caused by visual stimulation.

In addition, such a frequency of 20 Hz to 50 Hz performs flicker irradiation at a frequency of 50 Hz or less, that is, in other words, a power supply frequency in China, Japan, or European countries. Therefore, by using a frequency lower than the power supply frequency, the reliability of the fifth light source 1021 can be improved by flickering at a frequency lower than that of an illuminating device or LED used at a common power supply frequency.

In addition, the wavelength emitted by the fifth light source 1021 is blue or green, but may be an infrared wavelength that induces vibration 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 this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, it is preferable that the wavelength of the strongest absorption portion corresponds to a valley portion of the spectrum, for example. For example, "-CH3" exists as a functional group in a large amount in the molecular structure of harmful substances such as pesticides, and the infrared absorption spectrum of the "-CH3" functional group is 3378nm (wavenumber 2960/cm) and 3484nm (wavenumber 2870/cm). Therefore, wavelengths in the infrared region including 3378 nm (wave number 2960/cm) and 3484 nm (wave number 2870/cm) are used as the wavelength emitted by the fifth light source 1021 . Then, the light emitted from the fifth light source 1021 is likely to be decomposed in the “-CH3” portion of harmful substances such as pesticides.

In addition, wavelengths determined from the infrared absorption spectrum of organophosphorus pesticides such as chlorpyrifos, malathion, or quinaphos, or pyrethroid pesticides such as permethrin are preferred. These are pesticides that are used in large quantities in food and have a high possibility of remaining in food. In addition, organophosphorus pesticides are highly toxic pesticides compared with other types of pesticides, and their safety to the human body can be further improved by removing them as much as possible. In addition, since the wavelengths of these infrared rays exist in the range of 1250nm (wavenumber 800/cm) to 3333nm (wavenumber 3000/cm), the wavelength emitted by the fifth light source 1021 is preferably within this wavelength range.

In addition, the fifth light source 1021 can also be used as an ozone activation device by including the wavelength for ozone activation in the infrared wavelength of the fifth light source 1021 . For example, it is a wavelength in the infrared region that ozone absorbs. This is because when ozone is activated, decomposition of harmful substances such as agricultural chemicals is accelerated.

Therefore, wavelengths including the infrared region can also be used as an ozone activator that activates harmful substances such as pesticides and ozone at the same time, and has an additive effect of decomposing pesticides at a lower concentration of ozone.

In addition, the fifth light source 1021 is preferably a light emitting method that easily decomposes harmful substances such as pesticides. For example, it is considered that the fifth light source 1021 is driven only when the ozone concentration in the vegetable compartment 920 is above a predetermined value, that is, when the harmful substances such as pesticides are decomposed by ozone. The way of the fifth light source 1021 . The predetermined value is preferably 0.01 ppm or more in consideration of the decomposition efficiency of harmful substances such as pesticides. It is also an effective means to blink the fifth light source 1021 at light emission intervals corresponding to multiples and divisors of the natural frequency of the molecules constituting the pesticide. Thus, light energy can be efficiently injected into the pesticide, and molecular coupling of harmful substances such as the pesticide can be easily broken and decomposed by ozone.

In addition, in this embodiment, a light emitting diode is used as the fifth light source 1021, but it is not particularly limited, and the fifth light source 1021 that emits light may be used. In addition, when a structure in which a plurality of light emitting diodes emitting lights of different wavelengths are combined is used as the fifth light source 1021, a multi-layered effect can be further obtained.

On the other hand, the use of ozone to remove harmful substances is carried out through an oxidation reaction, so generally the higher the temperature, the more the oxidative decomposition is promoted, and the temperature of the ozone can be higher. In addition, since the amount of ozone generated from the ozone generator 1010 decreases due to a decrease in the resistance value in the circuit, the lower the temperature, the more it increases, and the risk of the ozone concentration in the vegetable compartment 903 becoming 0.03 ppm or higher increases. The amount of ozone generated by the ozone generator 1010 can make the temperature of the ozone generator 1010 higher, that is, the temperature of the gas environment near the ozone generator 1010 can be made into a higher temperature zone. In this way, by installing the ozone generator 1010 at a high temperature, the amount of ozone generation can be easily suppressed without using special means. Thus, by suppressing the amount of ozone, it is easy to control the low concentration of 0.03ppm ozone, and even the ozone concentration lower than 0.03ppm can further promote the decomposition of harmful substances such as agricultural chemicals.

Here, in this embodiment, the upper side in contact with the vegetable compartment 903, which is a storage compartment for supplying ozone, is the refrigerator compartment 902, and the adjacent lower side is the freezer compartment 904, so the upper surface of the vegetable compartment 903 is kept in contact with 5°C. The refrigerator compartment 902 is in contact with the freezer compartment 904 maintained at -18°C. Therefore, the vegetable compartment 903 is configured by maintaining the temperature of the vegetable compartment 903 at 5° C., and is also affected by the temperature of the adjacent storage compartment. That is, affected by the temperature of the upper refrigerator compartment 902 kept at 3°C and the lower freezer compartment 904 kept at -18°C, temperature unevenness occurs in the vegetable compartment 903, and the temperature of the upper part of the vegetable compartment 903 is higher than that of the vegetable compartment. The temperature of the lower part of 903 is high. In addition, in the front-back direction of the vegetable compartment 903, since the air cooled by the cooler 905 is blown from the cooling air passage 907 provided on the back side, the inside of the vegetable compartment 903 is exposed to cooler air, so the inside of the vegetable compartment 903 is relatively cold. Cold ahead. Therefore, although the vegetable compartment 903 has a structure maintained at 5° C., temperature unevenness occurs in the vegetable compartment 903 , and the temperature in the vegetable compartment 903 has the highest temperature zone in the front upper part.

Therefore, from the viewpoint of suppressing the ozone concentration, the installation position of the ozone generator 1010 is studied, it is easy to control the low concentration of 0.03ppm, and the ozonolysis of harmful substances such as pesticides can be further promoted, so the temperature of the ozone generator 1010 is maintained at Higher temperature is effective under the conditions of actual use, but as its practical method, higher temperature in the highest temperature band in the temperature distribution of the vegetable compartment 903 kept at 5°C, that is, in the adjacent storage room The ozone generator 1010 is arranged on the wall surface side of the belt storage room, that is, on the wall surface on the upper side of the vegetable compartment 903 .

Thus, in this embodiment, the ozone generator 1010 is arrange|positioned in the part with a high temperature distribution for the purpose of raising the temperature around the ozone generator 1010 as one of the ozone amount reduction devices.

In addition, in the present embodiment, vegetable compartment 903 is provided on the front side in the front-rear direction, and is provided on the front side of the heat insulating wall between vegetable compartment 903 and adjacent refrigerating compartment 902 .

However, depending on the type of the ozone generator 1010, it may be necessary to install it in a place that is difficult for the user to touch. In particular, when a high voltage flows into the ozone generator 1010, the user's safety needs to be considered, and it may be installed on the wall side of the adjacent storage room and on the rear side in the front-rear direction. In this case, it is preferable to provide it at an appropriate location in consideration of practical use.

In addition, in this embodiment, as the ozone amount reduction device, on the basis of the structure in which the ozone generator 1010 is installed in the above-mentioned high temperature zone, the ozone adsorption filter 1022 is installed in the storage room, and the ozone amount is reduced by reducing the amount of ozone. The device adopts the ozone adsorption filter 1022, so that the amount of ozone can be reduced in an energy-saving manner without using electric energy.

These ozone reduction devices can also be used independently, respectively, but the effect can be further enhanced by using them in combination.

In addition, as a method of accelerating the oxidative decomposition by ozone, there is a method of raising the pressure of ozone. As a means of using this method, when the ozone generator 1010 is driven, the refrigerator compartment shutter 908 and the freezer compartment shutter 910 can be closed, and the vegetable compartment shutter 909 can be opened to drive the fan 906 to The pressure of the vegetable compartment 903 rises. Thereby, ozone decomposition can be promoted.

On the other hand, harmful substances such as pesticides adhering to the surfaces of vegetables and fruits are efficiently decomposed by ozone at a low concentration of 0.03 ppm to produce decomposed substances. The decomposed substances are less harmful than the original harmful substances, but still produce substances that should be removed as much as possible. Therefore, the spray device 1023 serving as a decomposed matter reducing means for distributing water mist on the surfaces of vegetables and fruits stored in the vegetable compartment 903 is driven to reduce the decomposed matter. This is because harmful substances such as pesticides adhering to the surface of vegetables and fruits are decomposed by ozone, but the molecular weight of the decomposed substances after ozonolysis is smaller than that of the original harmful substances, and in addition, it is easy to decompose the harmful substances by the oxidation reaction using ozone. Since "-OH" or "=O" is formed on the functional group, it is easy to dissolve in water, and the decomposed substance is dissolved in the water mist sprayed by the spray device 1023 of the decomposed substance reduction device, thereby hydrolyzing.

In addition, as another aspect of the device for reducing decomposed substances, a UV lamp for irradiating ultraviolet wavelengths is provided, and the decomposed substances can be decomposed by irradiation of the UV lamp.

In addition, since the molecular weight of the decomposed substance is smaller than that of the original harmful substance, it may evaporate and float in the air. These evaporated and floated decomposed substances can be removed by a decomposition reaction using a light medium by replenishing the decomposed substances through a filter such as activated carbon containing a light medium on the cold air outlet path of the vegetable compartment 903 and irradiating light.

As above, in this embodiment, the ozone generator 1010 is provided on the vegetable compartment 903, and the harmful residual pesticides and the like that are attached to the surface of the vegetables stored in the vegetable compartment 903 are decomposed by the ozone generated by the ozone generator 1010. The ozone amount reduction device that reduces the amount of ozone from the vegetable compartment 903 after the substance can reliably suppress the amount of ozone even if the ozone concentration is increased due to any conditions.

In addition, the ozone amount reducing device of the present invention can further reliably reduce the amount of ozone by providing an ozone discharge mechanism that discharges the air in vegetable compartment 903 from vegetable compartment 903 to the outside of refrigerator 900 .

In addition, in this embodiment, in addition to the structure in which the ozone generating device 1010 is installed in the above-mentioned high temperature zone as the ozone reduction device, the ozone adsorption filter 1022 is also installed in the storage room, but the vegetable room 903 and the refrigerator Holes are opened on the partition plate of the store main body, a fan is installed, and the ozone discharge mechanism that discharges the air of the vegetable compartment 903 from the vegetable compartment to the outside of the refrigerator 900 is provided as an ozone reduction device, which can further reduce ozone, so it is preferable. According to this, even if the ozone concentration becomes high for any reason, the ozone can be quickly discharged, so that the user's safety can be further improved.

In addition, in this embodiment, the ozone adsorption filter 1022 is used as the ozone reduction device, but the UV lamp that irradiates ultraviolet rays can also be used as the ozone reduction device. The drive of 1011 decomposes harmful substances such as pesticides adhering to the surface of vegetables and fruits, and at the same time lights up a UV lamp that irradiates ultraviolet rays as an ozone reduction device and a decomposed substance reduction device. As a result, the ozone remaining after decomposing and removing harmful substances is irradiated with a UV lamp to decompose the ozone into oxygen molecules. As a result, the ozone filling the vegetable compartment 903 can be reliably removed.

In addition, as another device, it can be a water spray device. The water spray device sprays water on the surface of vegetables and fruits, and the ozone is partially dissolved in the water to make ozone water with a concentration of 0.03 ppm or more. And the pesticide lamp harmful substances on the surface of the fruit are decomposed by ozone.

In addition, in this embodiment, as the ozone amount reduction device of the ozone generator 1010, the purpose is to increase the temperature around the ozone generator 1010, and the ozone generator 1010 is arranged in a part with a high temperature distribution. The means for the temperature rise of the generating device 1010 can also prevent the temperature rise of the vegetable compartment 903 during the operation of the defrosting heater 912 in order to melt the frost attached to the cooler 905, and the vegetable compartment shutter 909 forms a closed state, but the defrosting heater After the operation of 912, the vegetable compartment shutter 909 is opened, the fan 906 is driven, and the thawed high-temperature air is introduced into the vegetable compartment 903, so that the temperature of the ozone generator 1010 is raised.

In addition, as a method of raising the temperature of another ozone generator 1010, in order to make the ozone generator 1010 high temperature, the ozone generator 1010 may be installed near the vegetable compartment heater 911 provided in the lower part of the vegetable compartment 903.

About the refrigerator 1100 comprised as mentioned above, the operation|movement is demonstrated below.

During the operation of refrigerator 1100, the high-temperature and high-pressure refrigerant compressed by the compressor is cooled and condensed by condenser 1105 to form a liquid refrigerant. The refrigerant condensed by the condenser 1105 flows to the first decompression device or the second decompression device through the switching valve, and is a decompressed low-pressure and low-humidity gas-liquid two-state refrigerant.

Here, the refrigerant flowing to the first decompression device flows through the refrigerating evaporator, evaporates in the freezer compartment 1103, cools the freezer compartment 1103 by the heat of evaporation, and is sucked into the compressor again.

In addition, the refrigerant flowing from the switching valve to the second decompression device flows from the refrigerating evaporator 1109 to the freezing evaporator, and evaporates in the refrigerating room 1104 and the freezing room 1103, thereby cooling the refrigerating room 1104 and the freezing room by the heat of evaporation and vaporization. Chamber 1103 is cooled and drawn again to the compressor.

Here, the cold air obtained by the heat of evaporation and vaporization of the liquid refrigerant in the refrigerating evaporator 1109 flows in the refrigerating cooling air passage 1116 through the fan 1117, and is blown from the first outlet 1118, the second outlet 1119, and the third outlet. The outlet 1120 and the fourth outlet 1121 blow out to cool the respective partitions.

In addition, the inside of the second storage box 1114 and the third storage box 1115 are cooled by the return air that cools the partitions other than the inside and outside of the box.

Then, the relatively high-temperature return air sucked in from the first suction port 1122, the second suction port 1123, and the third suction port 1124 causes the liquid refrigerant in the refrigeration evaporator 1109 to evaporate due to the temperature difference, and the heat is taken away to form a low temperature, and then The fan 1117 is directed into the cabinet to cool the partitions.

Next, the ozone generator 1127 located in the third storage box 1115 is driven to generate ozone gas. At this time, the third storage box 1115 for storing fruits and vegetables is filled with ozone gas. At this time, the filled ozone gas has a low concentration of 0.03ppm. Then, the filled low-concentration ozone gas contacts harmful substances such as pesticides attached to the surface of fruits and vegetables, and these harmful substances undergo oxidation and decomposition reactions with ozone to further reduce harmful substances and decompose them into safe substances. In addition, while the ozone gas is decomposed and removed, light is emitted from the sixth light source 1129 to activate the biological defense reaction of fruits and vegetables, and to increase the release of vitamin C as an antioxidant substance, and the increased vitamin C is released from the inside of fruits and vegetables. Oxidative decomposition of harmful substances such as pesticides.

In addition, at this time, since the ozone generator 1127 and the third storage box 1115 are located at the bottom of the refrigerator compartment 1104, ozone heavier than air can efficiently slip into the third storage box 1115. Thus, a small amount of ozone, such as 0.03 ppm, can be efficiently filled in the third storage box 1115 reliably, and the antibacterial preservation of the third storage box 1115 and the antibacterial preservation of food can be improved, and the amount of ozone adhering to the food can be reduced. Harmful substances such as pesticides can further improve food safety.

In addition, since the third storage box 1115 is located at the bottom, even when the ozone flows out of the refrigerator 1100 due to taking out and putting in the food, the high-concentration ozone can be used to quickly flow out downward, and the user The possibility of inhaling ozone into the body by the nose becomes low, and the refrigerator 1100 with higher safety can be provided.

In addition, on the other hand, the cold air blown out from the first outlet 1118, the second outlet 1119, the third outlet 1120, and the fourth outlet 1121 is cooled by natural convection to the third storage box 1115, and then is discharged to the second inlet. 1123 suction, and then return to the evaporator 1109 for refrigeration. In the circulation of such cold air, after the ozone gas generated from the ozone generator 1127 flows into the third storage box 1115, a part of the ozone gas is sucked from the second suction port 1123 by the air flow of the cold air circulation, and blows into the first blower. The outlet 1118, the second outlet 1119, the third outlet 1120, and the fourth outlet 1121 circulate. Therefore, the ozone gas spreads over the refrigeration cooling air duct 1116 and the entire refrigerator compartment 1104 . Thereby, not only the third storage box 1115, but also the refrigerating and cooling air passage 1116 where miscellaneous bacteria are more likely to multiply can concentrate antibacterial activity by ozone, and can more reliably realize the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food. , and reduce harmful substances such as pesticides attached to food, which can further improve food safety.

In addition, since the ozone generating device 1127 is provided with an ozone generating device in the storage compartment located on the most downstream side in the refrigerator compartment 1104, the storage compartment located on the most downstream side of the refrigerating and cooling air passage 1116 flows into the environment containing bacteria and the like in each storage compartment. air conditioner. Therefore, even though it is an environment where miscellaneous bacteria are easy to multiply in general, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of antibacterial preservation in storage rooms based on refrigeration temperature zones and the antibacterial preservation of food, and reduce the amount of bacteria attached to food. Harmful substances such as pesticides can further improve food safety.

In addition, the ozone generator 1127 does not need to be specially installed on the partition plate 1126 , and can also be installed in the refrigeration cooling air passage 1116 . Thereby, antibacterial can be reliably realized by ozone in the refrigerating and cooling air passage 1116 where miscellaneous bacteria are easy to multiply, and the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food can be realized more reliably, and the reduction of adhesion on Harmful substances such as pesticides on food can further improve food safety.

In addition, the ozone generating device 1127 may also be provided in the storage room or storage partition with the highest temperature among the storage rooms in the refrigerated temperature zone. Thus, due to the high temperature, even though it is an environment where bacteria are easy to multiply, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigerated temperature zone and the antibacterial preservation of food, and reduce Harmful substances such as pesticides attached to food can further improve food safety.

In addition, in this embodiment, an ozone adsorption filter 1131 is installed in the storage room as the ozone reduction device. By using the ozone adsorption filter 1131 as the ozone reduction device, it is possible to reduce the ozone amount in an energy-saving manner without using electric energy. .

These ozone reduction devices can also be used individually, respectively, but can also be used in combination.

On the other hand, harmful substances such as pesticides adhering to the surfaces of vegetables and fruits are efficiently decomposed by low-concentration ozone of 0.03 ppm to produce decomposed substances. The decomposed substance is a decomposed substance that is less harmful than the original hazardous substance but still needs to be removed as much as possible. Therefore, the decomposed matter reducing means is driven to reduce the decomposed matter by driving the water spraying device that sprays water mist on the surface of the vegetables and fruits stored in the third storage box 1115 .

In addition, as another aspect of the device for reducing decomposed substances, a UV lamp is provided, and the decomposed substances can be decomposed by irradiation of the UV lamp.

In addition, since the molecular weight of the decomposed substance is smaller than that of the original harmful substance, it may evaporate and float in the air. These evaporated and floating decomposed substances are discharged from the first outlet 1118 , the second outlet 1119 , the third outlet 1120 , and the fourth outlet 1121 through the refrigerating and cooling air passage 1116 sucked in from the second inlet 1123 , It will diffuse to the entire refrigerator compartment 1104, so the decomposed substance reducing device is not only installed on the third storage box 1115, but also preferably installed on the top surface of the refrigerator compartment 1104 in terms of safer use of the refrigerator 1100 by the user.

In addition, as another device for reducing decomposed substances, the decomposed substances can be removed by a decomposition reaction using a light medium by replenishing the decomposed substances through a filter such as activated carbon containing a light medium and irradiating light.

As mentioned above, in the embodiment of the present invention, the refrigerator 1100 includes: an insulated box with a plurality of heat-insulated partitions, a storage room with a refrigerated temperature zone in which the temperature inside the store is kept at the refrigerated temperature zone, And the temperature in the storeroom is maintained at the freezing temperature zone storage room in the freezing temperature zone, and there are refrigerating evaporators 1109 for cooling the refrigeration temperature zone storage room and freezing evaporators for cooling the freezing temperature zone storage room, An ozone generator 1127 that produces ozone supplied to the storage room in the refrigerated temperature band and an activation device that promotes the decomposition of harmful substances such as pesticides are provided, so that the ozone concentration in the lowermost storage room in the refrigerated temperature band storage room is the highest, so it can improve Based on the antibacterial preservation of the storage room in the refrigeration temperature zone and the antibacterial preservation of food, and the reduction of harmful substances such as pesticides attached to the food, the safety of the food can be further improved. Even if the food is taken out and put in, the ozone will flow into the refrigerator Even when it flows out of the refrigerator 1100, the high-concentration ozone can be quickly flowed downward, so that a safer refrigerator 1100 can be provided. The third storage box 1115 is used to reduce the amount of ozone after decomposing harmful substances such as residual pesticides attached to the surface of vegetables stored in the third storage box 1115 by the ozone generated by the ozone generator 1127. The ozone adsorption filter 1131 can reliably suppress the amount of ozone even if the ozone concentration is increased due to any conditions.

Moreover, the ozone amount reduction apparatus of this invention can reduce an ozone amount more reliably by providing the ozone discharge mechanism which discharges the air of the 3rd storage box 1115 from the 3rd storage box 1115 to the outside of the refrigerator 1100.

In addition, in this embodiment, a cover 1130 is provided in the third storage box 1115, but the present invention is not limited thereto, and the third storage box 1115 and its cover 1130 may not be present, and the storage box divided by the partition plate 1126 Store food directly in the space. Alternatively, the third partition device 1128 and the cover 1130 are separately formed structures, but it is not particularly limited, and the shape of the third partition device 1128 can also be formed into a shape in which the third storage box 1115 can be sealed, and a shape without a cover 1130 can be formed. .

In addition, since the ozone generator 1127 generates ozone gas in the storage space divided at the lowest position of the refrigerator compartment 1104, it is possible to reduce the chance that the ozone gas heavier than air directly contacts the user's face when the door of the refrigerator compartment 1100 is developed, Ozone gas is inhaled from the user's nose and mouth, and the possibility of inhalation into the human body is reduced, so the user can use refrigerator 1100 more safely.

In addition, the cold air blown out from the first outlet 1118, the second outlet 1119, the third outlet 1120 and the fourth outlet 1121 is sucked into the second inlet 1123 after cooling the third storage box 1115 by natural convection, and then returns The cold air cycle of the evaporator 1109 for refrigeration is heavy, and most of the ozone gas generated from the ozone generator 1127 flows into the third storage box 1115, although a part of the ozone gas is sucked from the second suction port 1123 by the circulating fluid of the cold air. , circulates to the first outlet 1118, the second outlet 1119, the third outlet 1120, and the fourth outlet 1121, so the ozone gas with an extremely low concentration spreads throughout the entire refrigerator compartment 1104. Thus, the oxidizing power of the extremely low-concentration ozone gas spread throughout the entire refrigerator compartment 1104 not only removes the residual pesticides in the fruits and vegetables stored in the third storage box 1115, but also removes the air in the refrigerator compartment 1104. smelly effect. In addition, it also has the antibacterial effect of ozone gas on other foods stored in the refrigerator compartment 1104 at the same time.

In addition, the refrigerator compartment door 1108 adopts one revolving door, but it is not limited thereto, and multiple doors can also be used. The third storage box 1115 adopts a storage box drawn from a pull-out door, and when the door is opened, the fruits and vegetables are directly drawn to the side. The way the third storage box 1115 is stored.

Here, utilizing the decomposition and removal of the ozone generated from the ozone generator 1310, the high-concentration oxidative decomposition is carried out as soon as possible for oxidative decomposition. As a result, these harmful substances can be efficiently decomposed. It has bad effects, and you may worry about its smell being noticed, so try to use a low concentration. Therefore, in order to keep the vegetable compartment 1203 at an ozone concentration that does not have a bad influence on the human body and the smell of ozone is not felt, that is, an ozone concentration below 0.03 ppm, the ozone generator 1310 is repeatedly stopped and the operation rate is controlled at 17%. , control the ozone concentration does not rise more than 0.03ppm.

On the other hand, when cooling vegetable compartment 1203 , the cooled cold air passes through cooling air passage 1207 by fan 1206 , blows toward vegetable compartment 1203 , and flows out. Therefore, the ozone filling the vegetable compartment 1203 enters an environment where it is easy to diffuse from the vegetable compartment 1203 along with the blown air during cooling and the cold air flowing out. Therefore, during the cooling of the vegetable compartment 1203, the operating rate of the ozone generator 1310 is controlled to 45%, and the operating rate of the ozone generating device is increased to compensate for the ozone lost from the vegetable compartment 1203 by diffusion. Thereafter, when the cooling of the vegetable compartment 1203 was stopped, the ozone generator 1310 supplied ozone to the vegetable compartment 1203 again at an operation rate of 17%.

In this way, when cold air flows into the vegetable compartment 1203, the ozone generator 1310 increases the supply of ozone at an operation rate of 45%, and when no cold air flows in, the ozone generator 1310 is operated at an operation rate of 17%. The cooled cold air is diffused from the vegetable compartment 1203 by the fan 1206, and by increasing the operating rate of the ozone generator 1310, it can also be efficiently and reliably injected into the vegetable compartment 1203 to decompose and adhere to the surface of the vegetables stored in the storage compartment. A small amount of ozone at 0.03ppm is aimed at the residual pesticides and other harmful substances.

That is, the ozone generating device 1310 that the vegetable room 1203 has can be low power, can realize the ozone concentration that more resource-saving, energy-conserving effect is played, and even if under the situation that just in case ozone flows out to the storage room, since it is relatively small The amount of ozone, so it can be said that it is a structure that takes the safety of the user into consideration.

In addition, an ozone concentration sensor may be attached to the vegetable compartment 1203 so that the ozone concentration does not increase, and the ozone generator 1310 may be controlled so that the ozone concentration in the vegetable compartment 1203 becomes 0.03 ppm or less.

In addition, the seventh light source 1321 as an activation accelerator is an LED element, but in order to efficiently activate the biological defense reaction of fruits and vegetables, blue light with a center wavelength of 470 nm is used as a wavelength for allowing light to permeate the surface of fruits and vegetables. It is preferable to use green light with a central wavelength of 520 nm as the wavelength of light directed toward the interior of fruits and vegetables. At this time, the irradiation intensity from the seventh light source 1321 having the blue LED and the green LED that irradiates the object (fruit and vegetable) is in the range of 5 lx to 500 lx.

With regard to the irradiation intensity, when the irradiation intensity is less than 5 lx, it is difficult to increase the vitamin as an antioxidant substance which increases the defense reaction of the living body under light irradiation. In addition, if the irradiation intensity is less than 5 lx, it is difficult for the user to recognize the brightness of the lighting when opening and closing the door, so it is actually difficult to obtain the effect promotion of the product when it is placed on the refrigerator. demands.

On the other hand, if it exceeds 500lx, the light intensity will be too strong, and the water evaporation of fruits and vegetables will be promoted on the contrary, and the freshness may be reduced. In addition, depending on the situation, the irradiated light may be bent or discolored, and the functional quality may deteriorate. Also, when the amount of light increases when the door is opened and closed, it tends to be difficult for the user as a consumer to enjoy the refreshing feeling as a refrigerator.

In view of this, as the light quantity of the seventh light source 1321, the brightness range of 20lx-100lx can realize the increase of vitamins as antioxidant substances on the functional level, and is an effective range that does not promote the evaporation of water from fruits and vegetables, and is sensory. When opening and closing, the user can experience the functional effect of the light irradiation from the seventh light source 1321 , and the brightness range that embraces a refreshing feeling is more preferable.

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

In addition, in an actual product, when checking the intensity of the irradiation ratio, the intensity of the brightness of the indoor space itself can be confirmed with a luminance meter. Specifically, also in the case of two-color irradiation, switching the control board etc. to irradiate each color and measuring the respective luminances can confirm the intensity of each wavelength, that is, the luminance of each color.

This is because green light has a wavelength that has no side effects on fruits and vegetables. Therefore, in order to increase the amount of vitamins in fruits and vegetables as an antioxidant substance and increase the intensity of green light penetrating into fruits and vegetables, the quality of fruits and vegetables will not be reduced. , can increase the amount of vitamins, so it is effective. According to experiments, it is found that the brightness of the green light is set to be 3 to 10 times that of the blue light, which is effective. That is, at a level of less than 3 times, the effect of increasing the amount of vitamins inside fruits and vegetables is insufficient, and at a level of more than 10 times, it is difficult to expect the effect of increasing the amount of vitamins on the surface of fruits and vegetables, and it is difficult to obtain a comprehensive result in either case. The effect of increasing the amount of vitamins.

In addition, the intermittent irradiation of fruits and vegetables can stimulate the vegetables more than the continuous lighting irradiation. In addition to photosynthesis to generate vitamin C, it can also promote the generation of vitamin C as an antioxidant in the defense reaction of vegetables, which can further promote the harmful effects of pesticides and other harmful substances. substance removal. Therefore, the seventh light source 1321 is preferably controlled to flash and irradiate (intermittently irradiate) the green LED and the blue LED simultaneously at any frequency in the range of 20-50 Hz around 40 Hz.

This causes a problem that, in the case where the slow flickering of 20 Hz or less can be clearly recognized by the user as flickering of intermittent illumination, the flickering of the light feels a warning such as notifying any abnormality, or a sense of psychological pressure is felt when the flickering continues to be sluggish. , or angry emotions such as irritability caused by visual stimulation.

In addition, such a frequency of 20 Hz to 50 Hz performs flicker irradiation at a frequency of 50 Hz or less, that is, in other words, a power supply frequency in China, Japan, or European countries. Therefore, by using a frequency lower than the power supply frequency, lighting devices or LEDs used at generally popular power supply frequencies are used, and flickering is performed at a frequency lower than that, thereby improving the reliability of the seventh light source 1321 .

In addition, the wavelength emitted by the seventh light source 1321 is blue or green, but may be an infrared wavelength that induces vibration 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 this wavelength is considered to exist in the infrared region. More specifically, using the infrared absorption spectrum of the target pesticide, it is preferable that the wavelength of the strongest absorption portion corresponds to a valley portion of the spectrum, for example. For example, "-CH3" exists as a functional group in a large amount in the molecular structure of harmful substances such as pesticides, and the infrared absorption spectrum of the "-CH3" functional group is 3378nm (wavenumber 2960/cm) and 3484nm (wavenumber 2870/cm). Therefore, wavelengths in the infrared region including 3378 nm (wave number 2960/cm) and 3484 nm (wave number 2870/cm) are used as the wavelength emitted by the seventh light source 1321 . Then, the light emitted from the seventh light source 1321 is likely to be decomposed in the “-CH3” portion of harmful substances such as pesticides.

In addition, wavelengths determined from the infrared absorption spectrum of organophosphorus pesticides such as chlorpyrifos, malathion, or quinaphos, or pyrethroid pesticides such as permethrin are preferred. These are pesticides that are used in large quantities in food and have a high possibility of remaining in food. In addition, organophosphorus pesticides are highly toxic pesticides compared with other types of pesticides, and their safety to the human body can be further improved by removing them as much as possible. In addition, since the wavelengths of these infrared rays exist in the range of 1250nm (wavenumber 800/cm) to 3333nm (wavenumber 3000/cm), the wavelength emitted by the seventh light source 1321 is preferably in this wavelength range.

In addition, the seventh light source 1321 can also be used as an ozone activation device by including the wavelength for ozone activation in the infrared wavelength of the seventh light source 1321 . For example, it is a wavelength in the infrared region that ozone absorbs. This is because when ozone is activated, decomposition of harmful substances such as agricultural chemicals is promoted.

Therefore, wavelengths including the infrared region can also be used as an ozone activator that activates harmful substances such as pesticides and ozone at the same time, and has an additive effect of decomposing pesticides at a lower concentration of ozone.

In addition, the seventh light source 1321 is preferably light-emitting in a way that easily decomposes harmful substances such as pesticides. For example, it is considered that the seventh light source 1321 is driven only when the ozone concentration in the vegetable compartment 1203 is above a predetermined value, that is, when the harmful substances such as pesticides are decomposed by ozone. The way of the seventh light source 1321 . The predetermined value is preferably 0.01 ppm or more in consideration of the decomposition efficiency of harmful substances such as pesticides. It is also an effective means to blink the seventh light source 1321 at light emission intervals corresponding to multiples and divisors of the natural frequency of the molecules constituting the pesticide. Thus, light energy can be efficiently injected into the pesticide, and molecular coupling of harmful substances such as the pesticide can be easily broken and decomposed by ozone.

In addition, in this embodiment, a light emitting diode is used as the seventh light source 1321 , but it is not particularly limited, and the seventh light source 1321 that emits light may also be used. In addition, when a structure in which a plurality of light emitting diodes emitting lights of different wavelengths are combined is used as the seventh light source 1321, a multi-layered effect can be further obtained.

On the other hand, the use of ozone to remove harmful substances is carried out through an oxidation reaction, so generally the higher the temperature, the more the oxidative decomposition is promoted, and the temperature of the ozone can be higher. In addition, since the amount of ozone generated from the ozone generator 1310 decreases due to the decrease in the resistance value in the circuit, the lower the temperature, the more it increases, and the risk of the ozone concentration in the vegetable compartment 1203 becoming 0.03 ppm or higher increases. The amount of ozone generated by the ozone generator 1310 can make the ozone generator 1310 have a higher temperature, that is, the gas ambient temperature near the ozone generator 1310 can be made into a higher temperature zone. In this way, by installing the ozone generator 1310 at a high temperature, the amount of ozone generation can be easily suppressed without using special means. Thus, by suppressing the amount of ozone, it is easy to control the low concentration of 0.03ppm ozone, and even the ozone concentration lower than 0.03ppm can further promote the decomposition of harmful substances such as agricultural chemicals.

Here, in this embodiment, the upper side in contact with the vegetable compartment 1203, which is a storage compartment for supplying ozone, is the refrigerator compartment 1202, and the adjacent lower side is the freezer compartment 1204, so the upper surface of the vegetable compartment 1203 is kept in contact with 5°C. The refrigerator compartment 1202 is in contact with the freezer compartment 1204 maintained at -18°C. Therefore, the vegetable compartment 1203 is configured by keeping the temperature of the vegetable compartment 1203 at 5° C., and is also affected by the temperature of the adjacent store room. That is, under the influence of the temperature of the refrigerating compartment 1202 kept at 3°C on the upper side and the freezer compartment at -18°C on the lower side, temperature unevenness occurs in the vegetable compartment 1203, and the temperature of the upper part of the vegetable compartment 1203 is higher than that of the vegetable compartment 1203. The temperature of the lower part is high. In addition, in the front-back direction of the vegetable compartment 1203, since the air cooled by the cooler 1205 is blown from the cooling air passage 1207 provided on the back side, the inside of the vegetable compartment 1203 is exposed to cooler air, so the inside of the vegetable compartment 1203 is relatively cold. Cold ahead. Therefore, although the vegetable compartment 1203 has a structure maintained at 5° C., temperature unevenness occurs in the vegetable compartment 1203 , and the temperature in the vegetable compartment 1203 has the highest temperature zone in the front upper part.

Therefore, from the viewpoint of suppressing the ozone concentration, the installation position of the ozone generator 1310 is studied, it is easy to control the low concentration of 0.03ppm, and the ozonolysis of harmful substances such as pesticides can be further promoted, so the temperature of the ozone generator 1310 is kept at A higher temperature is effective under the conditions of actual use, but as a practical method thereof, a higher temperature in the highest temperature band in the temperature distribution of the vegetable compartment 1203 maintained at 5°C, that is, in the adjacent storage room The ozone generator 1310 is arranged on the wall surface side of the belt storage room, that is, on the wall surface on the upper side of the vegetable compartment 1203 .

In this way, in this embodiment, as one of the ozone reduction devices, the ozone generator 1310 is arranged in a part with a high temperature distribution for the purpose of raising the temperature around the ozone generator 1310 .

In addition, in this embodiment, vegetable compartment 1203 is provided on the front side in the front-rear direction, and is provided on the front side of the heat insulating wall between vegetable compartment 1203 and adjacent refrigerator compartment 1202 .

However, depending on the type of the ozone generator 1310, it may be necessary to install it in a place that is difficult for the user to touch. In particular, when a high voltage flows into the ozone generator 1310, the user's safety needs to be considered, and it may be installed on the wall side of the adjacent storage room and on the rear side in the front-rear direction. In this case, it is preferable to provide it at an appropriate location in consideration of practical use.

In addition, in this embodiment, as the ozone amount reduction device, on the basis of the structure in which the ozone generator 1310 is installed in the above-mentioned high temperature zone, the ozone adsorption filter 1322 is installed in the storage room, and the ozone amount is reduced like this. The device adopts the ozone adsorption filter 1322, so that the amount of ozone can be reduced in an energy-saving manner without using electric energy.

These ozone reduction devices can also be used independently, respectively, but the effect can be further enhanced by using them in combination.

In addition, there is a method of raising the pressure of ozone as a method of accelerating the oxidative decomposition by ozone. As a means of utilizing this method, when the ozone generator 1310 is driven, the refrigerator compartment shutter 1208 and the freezer compartment shutter 1210 can be closed, and the vegetable compartment shutter 1209 can be opened to drive the fan 1206 to The pressure of the vegetable compartment 1203 rises. Thereby, ozone decomposition can be promoted.

On the other hand, harmful substances such as pesticides adhering to the surfaces of vegetables and fruits are efficiently decomposed by ozone at a low concentration of 0.03 ppm to produce decomposed substances. The decomposed substances are less harmful than the original harmful substances, but still produce substances that should be removed as much as possible. Therefore, the spraying device 1323 as a decomposed matter reducing means for distributing water mist on the surface of the vegetables and fruits stored in the vegetable compartment 1203 is driven to reduce the decomposed matter. This is because harmful substances such as pesticides adhering to the surface of vegetables and fruits are decomposed by ozone, but the molecular weight of the decomposed substances after ozonolysis is smaller than that of the original harmful substances, and in addition, it is easy to decompose the harmful substances by the oxidation reaction using ozone. Since "-OH" or "=O" is formed on the functional group, it is easy to dissolve in water, and the decomposed substance is dissolved in the water mist sprayed by the spray device 1323 of the decomposed substance reducing device, thereby hydrolyzing.

In addition, as another aspect of the device for reducing decomposed substances, a UV lamp for irradiating ultraviolet wavelengths is provided, and the decomposed substances can be decomposed by irradiation of the UV lamp.

In addition, since the molecular weight of the decomposed substance is smaller than that of the original harmful substance, it may evaporate and float in the air. These evaporated and floating decomposed substances can be removed by a decomposition reaction using a light medium by replenishing the decomposed substances through a filter such as activated carbon containing a light medium on the cold air outlet path of the vegetable compartment 1203, and irradiating light.

As above, in this embodiment, the ozone generator 1310 is provided on the vegetable compartment 1203, and the harmful residual pesticides, such as pesticides, adhering to the surface of the vegetables stored in the vegetable compartment 1203 are decomposed by the ozone generated by the ozone generator 1310. The ozone amount reduction device that reduces the amount of ozone from the vegetable compartment 1203 after the substance can reliably suppress the amount of ozone even if the ozone concentration is increased due to any conditions.

In addition, the ozone amount reduction device of the present invention can further reliably reduce the amount of ozone by providing an ozone discharge mechanism that discharges the air in vegetable compartment 1203 from vegetable compartment 1203 to the outside of refrigerator 1200 .

In addition, in this embodiment, in addition to the structure in which the ozone generating device 1310 is installed in the above-mentioned high temperature zone as the ozone reduction device, the ozone adsorption filter 1322 is also installed in the storage room, but the vegetable room 1203 and the refrigerator Holes are opened on the partition plate of the warehouse main body, a fan is installed, and the ozone discharge mechanism that discharges the air of the vegetable compartment 1203 from the vegetable compartment 1203 to the outside of the refrigerator 1200 is provided as an ozone reduction device, which can further reduce ozone, so it is preferred. According to this, even if the ozone concentration becomes high for any reason, the ozone can be quickly discharged, so that the user's safety can be further improved.

In addition, in this embodiment, the ozone adsorption filter 1322 is used as the ozone reduction device, but the UV lamp that irradiates ultraviolet rays can also be used as the ozone reduction device. The drive of 1311 decomposes harmful substances such as pesticides adhering to the surfaces of vegetables and fruits, and at the same time turns on a UV lamp that irradiates ultraviolet rays as an ozone reduction device and a decomposed substance reduction device. As a result, the ozone remaining after decomposing and removing harmful substances is irradiated with a UV lamp to decompose the ozone into oxygen molecules. As a result, the ozone filling the vegetable compartment 1203 can be reliably removed.

In addition, as another device, it can be a water spray device. The water spray device sprays water on the surface of vegetables and fruits, and the ozone is partially dissolved in the water to make ozone water with a concentration of 0.03 ppm or more. And the pesticide lamp harmful substances on the surface of the fruit are decomposed by ozone.

In addition, in this embodiment, as the ozone amount reduction device of the ozone generator 1310, the purpose of increasing the temperature around the ozone generator 1310 is to arrange the ozone generator 1310 in a part with a high temperature distribution. The means for the temperature rise of the generator 1310 is to melt the frost adhering to the cooler 1205. It is also possible to prevent the temperature rise of the vegetable compartment 1203 during the operation of the defrosting heater 1212. The vegetable compartment shutter 1209 forms a closed state, but the defrosting heater After the action of 1212, the vegetable compartment shutter 1209 is opened, the fan 1206 is driven, and the high-temperature air after thawing is introduced into the vegetable compartment 1203, so that the temperature of the ozone generator 1310 is raised.

In addition, as a method of raising the temperature of another ozone generator 1310, the ozone generator 1210 may be installed near the vegetable compartment heater 1211 provided in the lower part of the vegetable compartment 1203 in order to make the ozone generator 1310 high temperature.

In addition, FIG. 37 is a perspective view of a storage box, a partition plate, and an ozone generator of the refrigerator according to Embodiment 10 of the present invention. As shown in FIG. 37 , the ozone generator 1427 is buried on the lower surface side of the partition plate 1426 toward the inner side of the third storage box 1415 .

Thus, by burying the ozone generator 1427 in the partition plate 1426, even if the temperature of the 4th storage box 1425 changes, the temperature of the ozone generator 1427 is hard to change, and ozone generation efficiency can be maintained stably.

A hole 1433 is also provided in the lid 1430 of the third storage box 1415 . In addition, the fourth partition device 1428 is a member made of the ozone generator 1427 and a thin plate that divides the storage room, and holes are also provided on the lower surface of the fourth partition device 1428, and the ozone gas generated from the ozone generator 1427 is distributed in the fourth partition.

Light-emitting diodes (LEDs). Activated fruits and vegetables have increased vitamins as antioxidant substances, and decompose harmful substances such as pesticides by ozone, and decompose harmful substances such as pesticides attached to the surface of fruits and vegetables by vitamins increased in fruits and vegetables. Thereby, the decomposition of pesticides by ozone can be accelerated.

In addition, the eighth light source 1429 is disposed inside the partition plate 1426 . This is because the dew condensation of the eighth light source 1429 absorbs light of a predetermined wavelength, thereby preventing a decrease in the decomposition efficiency of the pesticide.

Therefore, at least the fourth partition device 1428 is preferably made of a light-transmitting material so as to sufficiently transmit light of a necessary wavelength among the lights emitted by the eighth light source 1429 .

In addition, the partition plate 1426 is provided with: the eighth light source 1429 used to promote the activation device for decomposing harmful substances attached to the surfaces of vegetables and fruits by the ozone generated by the ozone generator 1427, and to reduce the ozone generated by the ozone generator.

A spraying device that acts as a decomposed substance reduction device for decomposed substances generated after substances.

About the refrigerator 1400 comprised as mentioned above, the operation|movement is demonstrated below.

During the operation of refrigerator 1400, the high-temperature and high-pressure refrigerant compressed by the compressor is cooled and condensed by condenser 1405 to form a liquid refrigerant. The refrigerant condensed by the condenser 1405 flows to the first decompression device or the second decompression device through the switching valve, and is a decompressed low-pressure and low-humidity gas-liquid two-state refrigerant.

Here, the refrigerant flowing to the first decompression device flows through the refrigerating evaporator, evaporates in the freezer compartment 1403, cools the freezer compartment 1403 by the heat of evaporation and vaporization, and is sucked into the compressor again.

In addition, the refrigerant flowing from the switching valve to the second decompression device flows from the refrigerating evaporator 1409 to the freezing evaporator, and evaporates in the refrigerating chamber 1404 and the freezing chamber 1403, thereby cooling the refrigerating chamber 1404 and the freezing chamber by the heat of evaporation and vaporization. Chamber 1403 is cooled and drawn again to the compressor.

Here, the cold air obtained by the heat of evaporation and vaporization of the liquid refrigerant in the refrigerating evaporator 1409 flows in the refrigerating cooling air passage 1416 through the fan 1417, and is blown from the first air outlet 1418, the second air outlet 1419, and the third air outlet. The outlet 1420 and the fourth outlet 1421 blow out to cool the respective partitions.

In addition, the inside of the second storage box 1414 and the third storage box 1415 are cooled by the return air that cools the partitions other than the inside and outside of the box.

Then, the relatively high-temperature return air sucked in from the first suction port 1422, the second suction port 1423, and the third suction port 1424 causes the liquid refrigerant in the refrigeration evaporator 1409 to evaporate due to the temperature difference, and the heat is taken away to form a low temperature, and then The fan 1417 is directed into the cabinet to cool the partitions.

Next, the ozone generator 1427 located in the third storage box 1415 is driven to generate ozone gas. At this time, the third storage box 1415 for storing fruits and vegetables is filled with ozone gas. At this time, the filled ozone gas has a low concentration of 0.03ppm. Then, the filled low-concentration ozone gas contacts harmful substances such as pesticides attached to the surface of fruits and vegetables, and these harmful substances undergo oxidation and decomposition reactions with ozone to further reduce harmful substances and decompose them into safe substances. In addition, while the ozone gas is decomposed and removed, light is emitted from the eighth light source 1429 to activate the biological defense reaction of fruits and vegetables, and to increase the release of vitamin C as an antioxidant substance. Oxidative decomposition of harmful substances such as pesticides.

In addition, since the ozone generator 1427 and the third storage box 1415 are located at the bottom of the refrigerator compartment 1404 at this time, the ozone heavier than air can efficiently slip into the third storage box 1415 . Thus, it is possible to efficiently fill the third storage box 1415 with a small amount of ozone of 0.03 ppm reliably, and it is possible to realize the antibacterial preservation of the third storage box 1415 and the improvement of the antibacterial preservation of food, as well as the reduction of adhering to the food. Harmful substances such as pesticides can further improve food safety.

In addition, since the third storage box 1415 is located at the bottom, even when the ozone flows out of the refrigerator 1400 due to taking out and putting in the food, the high-concentration ozone can be used to quickly flow out downward, and the user The possibility of inhaling ozone into the body by the nose becomes low, and the refrigerator 1400 with higher safety can be provided.

In addition, on the other hand, the cold air blown out from the first outlet 1418, the second outlet 1419, the third outlet 1420, and the fourth outlet 1421 is cooled by natural convection to the third storage box 1415, and then is discharged to the second inlet. 1423 suction, and then return to the evaporator 1409 for refrigeration. In the circulation of such cold air, after the ozone gas generated from the ozone generator 1427 flows into the third storage box 1415, a part of the ozone gas is sucked from the second suction port 1423 by the air flow of the cold air circulation, and blows into the first blower. The outlet 1418, the second outlet 1419, the third outlet 1420, and the fourth outlet 1421 circulate. Therefore, the ozone gas spreads over the refrigeration cooling air duct 1416 and the entire refrigerator compartment 1404 . Thereby, not only the third storage box 1415, but also the refrigerating and cooling air passage 1416 where miscellaneous bacteria are more likely to multiply can concentrate antibacterial activity by ozone, and can more reliably realize the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food. , and reduce harmful substances such as pesticides attached to food, which can further improve food safety.

In addition, since the ozone generating device 1427 is provided with an ozone generating device in the storage subregion located on the most downstream side in the refrigerating and cooling air passage 1416 for cooling the refrigerating room 1404, the storage subregion located on the most downstream side of the refrigerating and cooling air passage 1416 flows into the storage subregion containing each Air-conditioning for bacteria, etc. in the storage partition. Therefore, even though it is an environment where miscellaneous bacteria are easy to multiply in general, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of antibacterial preservation in storage rooms based on refrigeration temperature zones and the antibacterial preservation of food, and reduce the amount of bacteria attached to food. Harmful substances such as pesticides can further improve food safety.

In addition, the ozone generator 1427 does not need to be specially installed on the partition plate 1426 , and can also be installed in the refrigeration cooling air passage 1416 . Thereby, antibacterial can be reliably realized by ozone in the refrigerating and cooling air passage 1416 where miscellaneous bacteria are easy to multiply, and the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food can be realized more reliably, and the reduction of adhesion on Harmful substances such as pesticides on food can further improve food safety.

In addition, the ozone generating device 1427 may also be provided in the storage room or storage partition with the highest temperature among the storage rooms in the refrigerated temperature zone. Thus, due to the high temperature, even though it is an environment where bacteria are easy to multiply, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigerated temperature zone and the antibacterial preservation of food, and reduce Harmful substances such as pesticides attached to food can further improve food safety.

In addition, in this embodiment, an ozone adsorption filter 1431 is installed in the storage room as the ozone reduction device. By using the ozone adsorption filter 1431 as the ozone reduction device, it is possible to reduce the ozone amount in an energy-saving manner without using electric energy. .

These ozone reduction devices can also be used individually, respectively, but can also be used in combination.

On the other hand, harmful substances such as pesticides adhering to the surfaces of vegetables and fruits are efficiently decomposed by low-concentration ozone of 0.03 ppm to produce decomposed substances. The decomposed substance is a decomposed substance that is less harmful than the original hazardous substance but still needs to be removed as much as possible. Therefore, the water spraying device 1432, which is the decomposed substance reducing device, is driven to spray water mist on the surface of the vegetables and fruits stored in the third storage box 1415, and the decomposed substance is reduced.

In addition, as another aspect of the device for reducing decomposed substances, a UV lamp is provided, and the decomposed substances can be decomposed by irradiation of the UV lamp. In addition, it is not limited to a UV lamp, and may be a light source as a device for emitting light.

In addition, since the molecular weight of the decomposed substance is smaller than that of the original harmful substance, it may evaporate and float in the air. These evaporated and floating decomposed substances are ejected from the first outlet 1418 , the second outlet 1419 , the third outlet 1420 and the fourth outlet 1421 through the refrigerating and cooling air passage 1416 sucked in from the second inlet 1423 , It will diffuse to the entire refrigerator compartment 1404, so the decomposed substance reducing device is not only installed on the third storage box 1415, but also preferably installed on the top surface of the refrigerator compartment 1404 from the perspective of the user using the refrigerator 1400 more safely.

In addition, as another device for reducing decomposed substances, the decomposed substances can be removed by a decomposition reaction using a light medium by replenishing the decomposed substances through a filter such as activated carbon containing a light medium and irradiating light.

As above, in the embodiment of the present invention, the refrigerator 1400 has: an insulated box with a plurality of heat-insulated partitions; And the temperature in the storeroom is maintained at the freezing temperature zone storage room in the freezing temperature zone, and there are refrigerating evaporators 1409 for cooling the refrigeration temperature zone storage room and freezing evaporators for cooling the freezing temperature zone storage room, The ozone generator 1427 that generates ozone supplied to the storage room with refrigeration temperature is provided, and the ozone generated by the ozone generation efficiency 1427 decomposes harmful substances such as residual pesticides adhering to the surface of vegetables stored in the storage room and decomposes the harmful substances after they are decomposed. The decomposed substance reduction device of the decomposed products of the refrigerated temperature zone makes the ozone concentration in the storage room at the bottom of the refrigerated temperature zone the highest, so it is possible to improve the antibacterial preservation of the storage room based on the refrigerated temperature zone and the antibacterial preservation of food, And reduce harmful substances such as pesticides adhering to the food, the safety of the food can be further improved, and even if the ozone flows out of the refrigerator 1400 by taking out and putting in the food, the high-concentration ozone can be quickly released to the refrigerator 1400. Outflow from below can provide a more secure refrigerator 1400 . In addition, at the same time, even when harmful substances such as pesticides adhering to the surface of vegetables are removed by ozonolysis, their harmfulness is lower compared with pesticides after decomposition, but since the decomposed substances that are desired to be removed as much as possible can be removed , so food can be provided to consumers in a more assured state.

In addition, after the harmful substances such as residual pesticides attached to the surface of vegetables stored in the third storage box 1415 are decomposed by the ozone generated by the ozone generation efficiency 1427, the ozone adsorption that reduces the amount of ozone in the third storage box 1415 is installed. The filter 1431 can reliably suppress the amount of ozone even if the ozone concentration increases due to any conditions.

Moreover, the ozone amount reduction apparatus of this invention can reduce an ozone amount more reliably by providing the ozone discharge mechanism which discharges the air of the 3rd storage box 1415 from the 3rd storage box 1415 to the outside of the refrigerator 1400.

In addition, in this embodiment, a cover 1430 is provided in the third storage box 1415, but the present invention is not limited thereto, and the third storage box 1415 and its cover 1430 may not be present, and the storage box divided by the partition plate 1426 Store food directly in the space. Alternatively, the fourth partitioning device 1428 and the cover 1430 are separately formed structures, but it is not particularly limited. The shape of the fourth partitioning device 1428 can also be formed into a shape that the third storage box 1415 can seal, and a shape without a cover 1430 can be formed. .

In addition, since the ozone generating device 1427 generates ozone gas in the storage space divided on the lowest position of the refrigerator compartment 1404, it is possible to reduce the chance that the ozone gas heavier than air directly contacts the user's face when the door of the refrigerator compartment 1400 is developed, Ozone gas is inhaled from the user's mouth and nose, and the possibility of inhalation into the human body is reduced, so the user can use refrigerator 1400 more safely.

In addition, the refrigerator compartment door 1408 adopts one revolving door, but it is not limited to this, and multiple doors can also be used. The third storage box 1415 adopts a storage box drawn from the pull-out door, and when the door is opened, the fruits and vegetables are directly drawn to the side. The storage method of the third storage box 1415.

Fig. 40 is a front view of the operation panel of the refrigerator according to Embodiment 11 of the present invention. In refrigerator 1500 , notification device 1652 for notifying the user of the effect and effectiveness of the function of improving the storage state of food is provided inside operation panel 1650 and vegetable compartment 1520 . The notification device provided on the operation panel 1650 is provided with a function notification device 1652a and a function notification device 1652a for notifying the effect and efficacy of the ozone generator 1600 as an improvement in the storage state of food and the ninth light source 1620 as shown in FIG. 40 . Function notification device 1652b of effect and efficacy. In addition, instead of using the display on the operation panel 1650 provided on the door surface, the ninth light source 1620, which is a functional device to improve the storage state of food, is provided inside the vegetable compartment 1520 when the door 1511b that is a revolving door is opened. The sensory notification device 1652c of the effect and efficacy of the action.

In this way, in this embodiment, there is a combination of a function notification device that displays the function and the effect itself in characters, etc., and a function notification device that can notify the user without reading characters. known device.

Moreover, on the operation panel 1650, the operation switch 1651a which can open and close the operation|movement of the ozone generator which is a function which improves the storage state of food is provided in the vicinity of the function notification device 1652a. Similarly, an operation switch 1651b capable of opening and closing the operation of the ninth light source 1620 as a function of improving the storage state of food is provided near the function notification device 1652b.

Moreover, the character "pesticide removal" which shows the effect and efficacy of the ozone gas which generate|occur|produces from the ozone generator 1600 is displayed on the operation switch 1651a. In addition, the text "vitamin improvement" indicating the effect and efficacy of the light emitted from the ninth light source 1620 is displayed on the operation switch 1651b.

In addition, in this embodiment, the function notification device 1652a, the function notification device 1652b, and the sensory notification device 1652c are light emitting diodes (LEDs) including light sources of visible light.

When the operation switch 1651a is pressed to start the operation of the ozone generating device 1600, the LED of the function notification device 1652a lights up, and the words "pesticide removal" as the effect of the function obtained by the operation of the ozone generating device 1600 become eye-catching, which is useful for users. The person reports that the function to obtain the effect of pesticide removal works. In addition, when the operation switch 1651a is pressed to end the function of the ozone generator 1600, the LED as the function notification device 1652a goes out, so that the characters of "pesticide removal" are no longer conspicuous, and the function of obtaining the effect of pesticide removal can be notified to the user. does not work.

Similarly, when the operation switch 1651b is pressed to start the function of the ninth light source 1620, the LED as the function notification device 1652b lights up, so that the words "vitamin improvement" become prominent, and the user is notified of the effect of improving nutritional elements. function is working. In addition, when the operation switch 1651b is pressed to end the ninth light source 1620, the LED as the function notification device 1652b goes out, the text "vitamin improvement" is no longer conspicuous, and the function of notifying the user of the effect of improving nutritional elements does not operate.

In addition, when the function of the ninth light source 1620 is active and the door 1511b is opened, the LED as the sensory notification device 1652c is lit, so that the user's sensory notification function is active, and the function of the ninth light source 1620 is no longer active. At this time, the LED as the ninth light source 1620 is turned off.

Here, the function notifying device 1652a directly informs the user that the effect and efficacy of ozone gas on food antibacterial and pesticide removal are "pesticide removal", but it is not limited thereto, and serves as a sign indicating the effect and efficacy of ozone gas. "Decomposition of pesticides", "antibacterial", "deodorizing", etc. can also be displayed. In addition, similarly, the function notification device 1652b uses the ninth light source 1620 to increase the effect and efficacy of vitamins in food as "vitamin improvement", but it is not limited thereto, and may also display "vitamin preservation", "vitamin preservation", "Vitamin saving", "Nutrition improvement" and so on.

In addition, the operation switch 1651a is a switch for opening and closing the ozone generator 1600, but by providing an LED light source in the operation switch 1651a, it can also be used as the function notification device 1652a. In addition, similarly, by providing a light source of an LED in the operation switch 1651b, thereby providing an LED, it is also possible to also serve as the function notification device 1652b.

The LED as the sensory notification device 1652c is installed above the vegetable compartment 1520 . Therefore, the front surface of the storage container 1521 is preferably made of a material that can sufficiently transmit light, so that the light emitted from the LED of the sensory notification device 1652c can pass through the storage container 1521 and reach the user.

In addition, here, the function notification device 1652b can also serve as the ninth light source 1620 because it is LED light. In this way, there is no need to specially install the function notifying device 1652b, and the installation space can be saved.

In addition, ozone generator 1600 is buried on the lower surface side of shelf 1515 as a heat insulating wall separating refrigerator compartment 1510 and vegetable compartment 1520 toward the inside of vegetable compartment 1520 . Therefore, the ozone generator 1600 is arranged above the opening 1527 of the storage container 1521 described later, at a position away from the opening 1527 of the storage container 1521 and at a position facing the opening 1527 .

Thus, by burying the ozone generator 1600 on the shelf 1515 as a heat insulating wall, even if the temperature of the vegetable compartment 1520 changes, it is difficult to change the temperature of the ozone generator 1600, and the ozone generation efficiency can be maintained stably.

Here, the ozone generator 1600 is a device that generates ozone, but is not particularly limited. Specifically, an apparatus that irradiates oxygen molecules (O ₂ ) in the air with ultraviolet rays to generate ozone (O ₃ ) or an electrode placed in the air at a high voltage to convert oxygen molecules in the air into Ozone equipment, equipment that electrolyzes oxygen-containing substances such as water, and supplies ozone to the air, etc.

Fig. 41 is a front view of the partition device of the refrigerator according to Embodiment 11 of the present invention. The fifth partition device 1610 is a member made of a thin plate that separates the ozone generator 1600 from the storage room. As shown in FIG. The fifth partition device 1610 covers the ozone generator 1600 buried in the heat insulating wall and is installed on the lower surface of the shelf 1515 as the heat insulating wall, thereby partitioning the ozone generating device 1600 and the vegetable compartment 1520 .

In addition, the fifth partition device 1610 is provided with a suction hole 1612 at the rear of the lower part. The suction hole 1612 disposed at the rear mainly functions as a hole for sucking the gas atmosphere outside the fifth partition device 1610 . In the case of the present embodiment, since the suction hole 1612 is located near a cool air discharge port 1613 described later, cool air in a relatively dry state is sucked in. Therefore, the humidity inside the fifth partition device 1610 can be kept low, and the ozone generation efficiency of the ozone generator 1600 can be maintained in a high state.

In addition, in this embodiment, by providing the fifth partition device 1610 between the storage container 1521 and the ozone generating device 1600, which has become high humidity due to the evaporation of moisture from the vegetables, the upper part of the fifth partition device 1610, That is, the periphery of the ozone generator 1600 is maintained at low humidity.

In addition, in the case where the ozone generator 1600 is configured to generate ozone by applying a high voltage, the ozone generator 1600 is installed near the cool air outlet 1613 where cold air flows in from the outside of the storage room and becomes low temperature in the temperature distribution of the storage room. , so that the inside of the fifth partition device 1610 becomes low temperature, so that ozone can be generated with higher efficiency. Therefore, power consumption necessary for ozone generation can be suppressed, contributing to energy saving.

In addition, the fifth partition device 1610 can adjust the ozone concentration of the vegetable compartment 1520 according to the relationship between the ozone generation efficiency of the ozone generator 1600, the amount of oxygen flowing into the fifth partition device 1610 from the suction hole 1612, and the amount of ozone flowing out from the discharge hole 1611. .

That is, the fifth partition device 1610 can adjust the ozone concentration of the vegetable compartment 1520 to some extent by determining the total opening area of the discharge holes 1611 and the total area of the suction holes 1612 provided in the fifth partition device 1610 at the design stage. Specifically, when there are many discharge holes 1611 (total opening area is large), the outflow amount of ozone increases, and the ozone concentration in vegetable compartment 1520 becomes high. In addition, the inflow of oxygen increases in proportion to the outflow of ozone, so the number of discharge holes 1611 is proportional to the ozone concentration of the vegetable compartment 1520 within the limit of the capacity of the ozone generator 1600 . On the contrary, when there are few discharge holes 1611 (total opening area is small), the outflow amount of ozone is small, and the ozone concentration in vegetable compartment 1520 is low.

In addition, the above-mentioned fifth partition device 1610 flows out ozone and flows in oxygen by natural convection, but a fan may be used to force ozone to flow out and oxygen to flow in. In addition, it is also possible to arrange the ozone concentration meter in a manner that can measure the ozone concentration in the storage container 1521, and adjust (for example, switch on and off the fan) the ozone generation amount of the ozone generator 1600 according to the information from the cover ozone concentration meter, so that the storage container The ozone concentration in 1521 was kept within the specified range.

Fig. 42 is a perspective view showing a cover of the refrigerator according to Embodiment 11 of the present invention, and Fig. 43 is a cross-sectional view showing a passage hole of the cover of the refrigerator.

The lid 1522 is a plate-shaped member that closes the opening of the storage container 1521 , and has a passage hole 1524 and an adjustment hole 1525 . In addition, the cover 1522 is made of a material capable of sufficiently transmitting light having a necessary wavelength among the light emitted from the ninth light source 1620 . The cover 1522 is a part that has the function of adjusting the humidity in the storage container 1521. Specifically, the moisture evaporated from the vegetables stored in the storage container 1521 is maintained in the storage container 1521 to a certain extent, and at the same time, it is kept in the storage container 1521. Regulate the humidity inside to the extent that the moisture does not condense.

Passage hole 1524 is a hole mainly having a function of passing ozone, and penetrates through in the thickness direction of cover 1522 . In addition, as shown in FIG. 42 , the passage hole 1524 has a tapered shape gradually increasing in diameter upward. In addition, the passage hole 1524 is a hole for introducing the ozone generated by the ozone generator 1600 into the inside of the storage container 1521 .

By forming the passing hole 1524 in the above shape, the ozone falling from the discharge hole 1611 of the fifth partition device 1610 can be received by the larger diameter portion of the passing hole 1524, and the ozone can be efficiently introduced into the storage container 1521. On the other hand, the moisture existing inside the storage container 1521 can match the outflow amount of the adjustment hole 1525 described later, and the humidity inside the storage container 1521 can be adjusted according to the design.

In addition, in the present embodiment, it is preferable to maintain the ozone concentration in the vegetable compartment 1520 and the third storage container 1521 which are food storage compartments at 0.05 ppm or less. This is because there is a concern that when the ozone concentration is high and foods such as vegetables are taken out of the storage container 1521, there is a concern that it will have any influence on the human body performing these operations. In addition, it is preferably maintained at 0.03 ppm or less. This is because when the concentration of ozone is high, the odor of ozone will give discomfort to the people who perform the work. However, when the ozone concentration is as low as 0.05ppm or less, the concentration is too low to decompose harmful substances such as pesticides, but on the other hand, ozone gas activates the biological defense reaction of vegetables and fruits and increases the effect of vitamins , so not only the harmful substances such as pesticides are directly decomposed by ozone gas, but also harmful substances such as pesticides can be decomposed from the inside through the vitamins added in fruits and vegetables, so even the low concentration of ozone gas below 0.05ppm can decompose and remove harmful substances such as pesticides .

It was actually confirmed that the ozone generator 1600 located in the vegetable compartment 1520 was driven to generate 0.03 ppm of ozone gas, and the filled low-concentration ozone gas removed harmful substances such as pesticides adhering to the surfaces of fruits and vegetables. As a result, 0.067 μg/cm ² of the organophosphorus pesticide malathion was attached to both stalks cut into 4 x 4 cm, and then decomposed and removed for 24 hours. As a result, malathion on the stalks was confirmed. The removal rate was 93%. Even low-concentration ozone gas will not harm the user's health, and can decompose and remove harmful substances such as pesticides adhering to the surfaces of vegetables and fruits.

Furthermore, since ozone gas also has an effect of reducing ethylene gas, food such as vegetables can be prevented from deteriorating, such as vegetables being browned by the etching gas.

In addition, as the LED element of the ninth light source 1621 of the activation promoting device, in order to efficiently activate the biological defense reaction of fruits and vegetables, blue light with a center wavelength of 470 nm is used as the wavelength for allowing light to permeate the surface of fruits and vegetables. It is preferable to use green light with a central wavelength of 520 nm as the wavelength toward the interior of fruits and vegetables. At this time, the intensity of irradiation from the ninth light source 1620 having blue LEDs and green LEDs to irradiate the target object (fruit and vegetable) is in the range of 5 lx to 500 lx.

With regard to the irradiation intensity, when the irradiation intensity is less than 5 lx, it is difficult to increase the vitamin as an antioxidant substance which increases the defense reaction of the living body under light irradiation.

On the other hand, if it exceeds 500lx, the light intensity will be too strong, and the water evaporation of fruits and vegetables will be promoted on the contrary, and the freshness may be reduced. In addition, depending on the situation, the irradiated light may be bent or discolored, and the functional quality may deteriorate. Also, when the amount of light increases when the door is opened and closed, it tends to be difficult for the user as a consumer to enjoy the refreshing feeling as a refrigerator.

In view of this, as the light quantity of the ninth light source 1621, the brightness range of 20lx to 100lx can realize the increase of vitamins as antioxidant substances on the functional level, and is an effective range that does not promote the evaporation of fruits and vegetables, and is sensory. When opening and closing, the user can experience the functional effect of the light irradiation from the ninth light source 1620, and the brightness range that embraces a refreshing feeling is more preferable.

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

In addition, in an actual product, when checking the intensity of the irradiation ratio, the intensity of the brightness of the indoor space itself can be confirmed with a luminance meter. Specifically, also in the case of two-color irradiation, switching the control board etc. to irradiate each color and measuring the respective luminances can confirm the intensity of each wavelength, that is, the luminance of each color.

In addition, the wavelengths emitted by the ninth light source 1620 are blue and green, but infrared wavelengths that induce vibrations of molecules constituting harmful substances such as pesticides may also be increased. This is because harmful substances such as agricultural chemicals adhering to the food surface can be efficiently decomposed and removed by the ozone gas generated from the ozone generator 1600 .

In addition, as the wavelength including the infrared region, more specifically, the infrared absorption spectrum of the target pesticide is used, and the wavelength corresponding to the valley portion of the spectrum, such as the wavelength of the strongest absorption portion, is preferable. For example, "-CH3" exists as a functional group in a large amount in the molecular structure of harmful substances such as pesticides, and the infrared absorption spectrum of the "-CH3" functional group is 3378nm (wavenumber 2960/cm) and 3484nm (wavenumber 2870/cm). Therefore, wavelengths in the infrared region including 3378 nm (wave number 2960/cm) and 3484 nm (wave number 2870/cm) are used as the wavelength emitted by the ninth light source 1620 . Then, the light emitted from the ninth light source 1620 is likely to decompose in the “-CH3” portion of harmful substances such as pesticides.

In addition, infrared rays emitted from organophosphorus pesticides such as chlorpyrifos, malathion, or quinoxaphos, or pyrethroid pesticides such as permethrin are preferred. The absorption spectrum determines the wavelength. These are pesticides that are used in large quantities in food and have a high possibility of remaining in food. In addition, organophosphorus pesticides are highly toxic pesticides compared with other types of pesticides, and their safety to the human body can be further improved by removing them as much as possible. In addition, since the wavelengths of these infrared rays exist in the range of 1250nm (wavenumber 800/cm) to 3333nm (wavenumber 3000/cm), the wavelength emitted by the ninth light source 1620 is preferably in this wavelength range.

In addition, the ninth light source 1620 can also be used as an ozone activation device by including the wavelength for ozone activation in the infrared wavelength of the ninth light source 1620 . For example, it is a wavelength in the infrared region that ozone absorbs. This is because when ozone is activated, decomposition of harmful substances such as agricultural chemicals is promoted.

In addition, the ninth light source 1620 is disposed inside the fifth partition device 1610 . This is to prevent light of a predetermined wavelength from being absorbed due to dew condensation on the ninth light source 1620 .

Therefore, at least the fifth partition device 1610 is preferably made of a material capable of sufficiently transmitting light of a necessary wavelength among the light emitted by the ninth light source 1620 .

In addition, refrigerator 1500 is provided with a cooling device. In the case of this embodiment, the cooling device is constituted by a cold air circulation provided with two coolers. Specifically, a first cooler 1512a is provided at the rear side of the inner portion of the refrigerating room 1510 . The inner portion of the refrigerator compartment 1510 is cooled by heat conduction from the first cooler 1512a. The air in the refrigerator compartment 1510 is cooled by the cooled inside.

In addition, the second cooler 1512b is provided on the rear side of the freezer compartment 1530 . The inside of the freezer compartment 1530 is cooled by the cold air forcibly passing through the second cooler 1512b, and the cold air for cooling food etc. returns to the second cooler 1512b again.

The cool air released from the second cooler 1512 b is also supplied to the vegetable compartment 1520 through the cool air outlet 1613 . Vegetable compartment 1520 is controlled to control the amount of cool air supplied by opening and closing the damper, and maintains a temperature range between the temperature range of refrigerator compartment 1510 and the temperature range of freezer compartment 1530 . Specifically, it is controlled to maintain the temperature within the range of 4°C or lower and 0°C or higher.

About the food storage comprised as mentioned above, the operation|movement and effect|action are demonstrated below.

The cooling device of refrigerator 1500 is driven to cool refrigerator compartment 1510 , vegetable compartment 1520 , and freezer compartment 1530 . At this time, the vegetable compartment 1520 is cooled to approximately 4°C. Fruits and vegetables are kept in the vegetable compartment 1520 .

Here, when the user wants to perform antibacterial treatment on the fruits and vegetables stored in the vegetable compartment 1520 or remove harmful substances such as pesticides adhering to the surfaces of the fruits and vegetables, he presses the button printed with "pesticide removal" on the operation panel 1650 provided on the door 1511a. The action switch 1651a of the character of the letter drives the ozone generator 1600 to generate ozone gas in the vegetable compartment 1520 . In this way, the food stored in the vegetable compartment 1520 is subjected to antibacterial and pesticide removal operations by the generated ozone gas. The user recognizes that the effect and effect of the ozone gas on antibacterial food and pesticide removal are acting by turning on the LED as the function notification device 1652a provided on the surface of the door 1511a.

In addition, when the user wants to increase the vitamin C of the fruits and vegetables stored in the vegetable compartment 1520, the user presses the operation switch 1651b printed with the words "enhance microorganisms" that emits light from the ninth light source 1620 of the operation panel 1650, and drives the ninth light source 1620. The light source 1620 emits light to the vegetable compartment 1520, and the emitted light activates the ecological defense reaction of fruits and vegetables stored in the vegetable compartment 1520 to increase vitamins. The user can know that the ozone gas has antibacterial and pesticide removal effects and effects on food by turning on the LED as the function notification device 1652a on the surface of the door 1511a, that is, the ninth light source 1620 is turned on.

That is, the user will not use the ozone generator 1600 to generate ozone gas in the vegetable compartment 1520 without knowing the effect and effect of emitting light to the vegetable compartment 1520 by operating the ozone generator 1600. Functional action is based on the understanding of the effect and efficacy of "removal of pesticides" and "increase of vitamins" having these functions.

In this way, the user can easily understand whether the food stored in the vegetable compartment 1520 is stored in the refrigerator 1500 or not by using the operation switch 1651a printed with the characters "pesticide removal" or the operation switch 1651b printed with the characters "vitamin improvement". In the case of removing pesticides or adding vitamins to vegetables and fruits, it is possible to simplify the use of such functions and improve the convenience of use.

In addition, here, when the user actually opens the door 1511b and stores food in the storage container 1521, during the operation of the ninth light source 1620, the LED as the sensory notification device 1652c lights up to confirm whether the ninth light source 1620 is is working.

Thus, when the user puts in and takes out food from the vegetable compartment 1520, he must confirm whether the ninth light source 1620 is working by turning on the sensory notification device 1652c, and does not need to set up and confirm the sensory notification on the door 1511a. The device 1652b can easily recognize the function of "increasing vitamins" of the ninth light source 1620, so the user can recognize it more easily.

In addition, since the ninth light source 1620 is green and blue LEDs, it can also be used as a visible light LED of the sensory notification device 1652c. Thereby, there is no need to install the sensory notification device 1652c, the manufacturing cost can be improved, the storage space in the vegetable compartment 1520 is light, and the convenience of use can be improved.

In addition, the ninth light source 1620 lights up green and blue LEDs, but the intermittent irradiation of fruits and vegetables stimulates the vegetables more than the continuous lighting irradiation. In addition to producing vitamin C through photosynthesis, it can also promote the defense reaction of vegetables. The production of vitamin C, which is an antioxidant substance, can further promote the removal of harmful substances such as pesticides. Therefore, the ninth light source 1620 is preferably controlled to flash and irradiate (intermittently irradiate) the green LED and the blue LED simultaneously at any frequency in the range of 20-50 Hz around 40 Hz. This causes a problem that, in the case where the slow flickering of 20 Hz or less can be clearly recognized by the user as flickering of intermittent illumination, the flickering of the light feels a warning such as notifying any abnormality, or a sense of psychological pressure is felt when the flickering continues to be sluggish. , or angry emotions such as irritability caused by visual stimulation.

In addition, such a frequency of 20 Hz to 50 Hz performs flicker irradiation at a frequency of 50 Hz or less, that is, in other words, a power supply frequency in China, Japan, or European countries. Therefore, by using a frequency lower than the power supply frequency, lighting devices or LEDs used at commonly used power supply frequencies are used, and flickering is performed at a frequency lower than that, thereby improving the reliability of the ninth light source 1620 .

Thus, when the ninth light source 1620 is blinking, the user can use the blinking light to confirm the increased effect and efficacy of the vitamins of the ninth light source 1620 when opening and closing the door, and it is easier than when the ninth light source 1620 is continuously lit. By calling the user's attention, it is possible to more efficiently recognize whether or not the ninth light source 1620 is operating, and as a result, it is possible to further improve usability.

In addition, it is preferable that the operation switch 1651b also serves as a vegetable compartment temperature setting switch for switching the temperature setting of the vegetable compartment 1520 . In this way, one operation button can be reduced, so costs such as material costs when manufacturing refrigerator 1500 can be reduced.

In addition, it is preferable to switch the preset temperature of vegetable compartment 1520 from 0°C to 5°C using a cooling device. In this way, the vegetable compartment 1520 can preserve not only vegetables and fruits, but also meat and fish suitable for preservation at 0°C or 1°C.

In addition, here, it is preferable that ninth light source 1620 operates when vegetable compartment 1520 is set at 2°C to 5°C, and does not operate when set at 0°C to 1°C. This is because the type of food stored in the vegetable compartment 1520 is suitable for storing fruits and vegetables such as vegetables and fruits when it is set at 2° C. to 5° C. By lighting up, it can be recognized that the temperature zone where vegetables and fruits can be stored is set. Conversely, when the ninth light source 1620 is not turned on, it is easy to recognize that the vegetable compartment 1520 is set at 0°C to 1°C, which is not the temperature zone for storing vegetables and fruits, but the temperature zone for storing meat and fish. .

As above, the refrigerator 1500 of the present invention has a storage box forming a storage room for storing food, a functional device for opening and closing the door of the storage box, and improving the storage state of the food stored in the storage room, and has a function of notifying the user.

Improve ease of use.

In addition, since the notification device reports by light or sound when the door is opened, the user can report whether the effect and effect of the function of improving the storage state of the food are in operation when the user opens the door, so the user opens the refrigerator 1500. The effect and effectiveness of the function of improving the storage state of the food will be recognized when taking out or storing it through the door, and the user can more easily recognize the effect of improving the storage state of the food without specifically confirming the notification device installed on the door. Functional effects and efficacy.

Thereby, even when the ozone gas improves the storage state of the food, which is difficult for the user to visually or olfactorily recognize, the effect of the function of improving the storage state of the food by the ozone gas can be reported by the effect reporting device. In addition, since the functional device is a light source, the function of improving the storage state of food uses a light source, so the light emitted from the light source recognizes whether the effect and efficacy of the function of improving the storage state of food are in operation when the user opens the door, so A light source can also be used as a notification device.

Since the functional device is a blue and green flashing light source, the function of improving the storage state of food by lighting up when the user opens the door is adopted, so when the user opens the door, the flickering of the light source is more likely to attract the user's attention to improve the storage of food Whether the effect and effect of the function of the state are in the action, so the user can recognize it more easily. In addition, the function of improving the storage state of food can be performed more efficiently by blinking.

In addition, in this embodiment, the storage container 1521 is provided in the vegetable compartment 1520, but the present invention is not limited thereto, and food may be directly stored in the storage container 1521 or the vegetable compartment 1520 without a cover.

In addition, the notification device 1652 adopts a light source using an LED, but is not limited thereto, and may be a sound device that transmits a warning sound or a function to the user by sound.

In addition, the door 1511b of the vegetable compartment 1520 is a revolving door, but it is not particularly limited, and may be a pull-out door.

In addition, in this embodiment, a light emitting diode is used as the ninth light source 1620 , but it is not particularly limited, and the ninth light source 1620 that emits light may also be used.

The operation|movement of refrigerator 1700 comprised as mentioned above is demonstrated below.

During the operation of the refrigerator 1700, the high-temperature and high-pressure refrigerant compressed by the compressor is condensed in the condenser 1705 to form a liquid refrigerant. The refrigerant condensed in the condenser 1705 flows to the first decompression device or the second decompression device through the switch valve, and is decompressed to form a low-pressure and low-temperature gas-liquid two-state refrigerant.

Here, the refrigerant flowing to the first decompression device flows through the refrigerating evaporator, evaporates in the freezer compartment 1703, cools the freezer compartment 1703 by the heat of evaporation, and is sucked into the compressor again.

Here, the refrigerant flowing to the second decompression device through the switching valve flows from the refrigerating evaporator 1709 to the freezing evaporator, and evaporates in the refrigerating chamber 1703 and the freezing chamber 1730, and the heat of evaporation and vaporization is applied to the refrigerating chamber 1704 and the refrigerating chamber 1704. The inside of the freezer compartment 1703 is cooled and sucked into the compressor again.

Here, the cool air obtained by the heat of evaporation and vaporization of the liquid refrigerant in the refrigerating evaporator 1709 flows through the cooling air passage 1716 by the fan 1717, and flows from the first air outlet 1718, the second air outlet 1719, and the third air outlet. 1720 and the fourth outlet 1721 blow out to cool each partition.

In addition, the return air that cools the other compartments in the second storage box 1714 and the third storage box 1715 flows through the inside and outside of the box to be cooled.

Here, the user stores fruits and vegetables in the third storage box 1715, and when he wants to perform antibacterial treatment on the fruits and vegetables stored in the third storage box 1715 or remove harmful substances such as pesticides attached to the surface of the fruits and vegetables, he presses the On the operation panel 1650 on the door 1508 , the operation switch 1651 a with the words "pesticide removal" printed thereon drives the ozone generator 1727 to generate ozone gas in the third storage box 1715 . In this way, antibacterial and pesticide removal operations are performed on the food stored in the third storage box 1715 by the generated ozone gas. The user recognizes that the effect and efficacy of the ozone gas on antibacterial food and pesticide removal are acting by turning on the LED as the function notification device 1652a provided on the surface of the door 1508 .

In addition, since the ozone generator 1727 and the third storage box 1715 are located at the bottom of the refrigerator compartment 1704 at this time, the ozone heavier than air can efficiently slip to the third storage box 1715 . Thus, it is possible to efficiently fill the third storage box 1715 with a small amount of ozone of 0.03 ppm reliably, and it is possible to realize the antibacterial preservation of the third storage box 1715 and the improvement of the antibacterial preservation of food, as well as the reduction of adhering to the food. Harmful substances such as pesticides can further improve food safety.

In addition, the user recognizes that the effect and effect of the ozone gas on food antibacterial and pesticide removal are acting by lighting up the LED as the function notification device 1652a provided on the surface of the door 1511a, so it is possible to provide a higher security. Freezer 1700.

In addition, since the third storage box 1715 is located at the bottom, even when the ozone flows out of the refrigerator 1700 due to taking out and putting in the food, the high-concentration ozone can be used to quickly flow out downward, and the user The possibility of inhaling ozone into the body by the nose becomes low, and the refrigerator 1700 with higher safety can be provided.

In addition, on the other hand, the cold air blown out from the first outlet 1718, the second outlet 1719, the third outlet 1720, and the fourth outlet 1721 is cooled by natural convection to the third storage box 1715, and then is discharged to the second inlet. 1723 suction, and then return to the evaporator 1709 for refrigeration. In the circulation of such cold air, after the ozone gas generated from the ozone generator 1727 flows into the third storage box 1715, a part of the ozone gas is sucked in from the second suction port 1723 by the air flow of the cold air circulation, and blows into the first blower. The outlet 1718, the second outlet 1719, the third outlet 1720, and the fourth outlet 1721 circulate. Therefore, the ozone gas spreads over the refrigeration cooling air duct 1716 and the entire refrigerator compartment 1704 . Thereby, not only the third storage box 1715, but also the refrigerating and cooling air duct 1716 where miscellaneous bacteria are more likely to multiply can concentrate on the antibacterial effect of ozone, and can more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food. , and reduce harmful substances such as pesticides attached to food, which can further improve food safety.

In addition, since the ozone generating device 1727 is provided in the storage subregion located at the most downstream side in the refrigerator compartment 1704, the storage subregion located at the most downstream side of the refrigerating and cooling air passage flows into the storage subregion including various bacteria and the like in each storage subregion. air conditioner. Therefore, even though it is an environment where miscellaneous bacteria are easy to multiply in general, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of antibacterial preservation in storage rooms based on refrigeration temperature zones and the antibacterial preservation of food, and reduce the amount of bacteria attached to food. Harmful substances such as pesticides can further improve food safety.

In addition, the ozone generator 1727 does not need to be specially installed on the partition plate 1726 , and can also be installed in the refrigeration cooling air passage 1716 . Thereby, antibacterial can be reliably achieved by ozone in the refrigerating and cooling air passage where miscellaneous bacteria are easy to multiply, and the antibacterial preservation of the storage room based on the refrigerating temperature zone and the antibacterial preservation of food can be realized more reliably, and the reduction of adhesion to food can be achieved. Harmful substances such as pesticides on the surface can further improve food safety.

In addition, the ozone generating device 1727 may also be provided in the storage room or storage partition with the highest temperature among the storage rooms in the refrigerated temperature zone. Thus, due to the high temperature, even though it is an environment where bacteria are easy to multiply, it is possible to achieve antibacterial concentration by ozone, and it is possible to more reliably realize the improvement of the antibacterial preservation of the storage room based on the refrigerated temperature zone and the antibacterial preservation of food, and reduce Harmful substances such as pesticides attached to food can further improve food safety.

As above, the food storage 1700 of the present invention has an insulated box with a plurality of heat-insulated partitions, a storage room with a refrigerated temperature zone on which the temperature in the insulated box is kept in the refrigerated temperature zone, and a storage room with a temperature in the refrigerated temperature zone.

The door, the functional device that improves the storage state of the food stored in the storage room, the sensory notification device that notifies the user of the effect and efficacy of the functional device on the food, the functional device is located at the bottom of the storage room in the refrigerating temperature zone, so it can Improving the antibacterial preservation of the storage room based on the refrigeration temperature zone and the antibacterial preservation of food, and reducing harmful substances such as pesticides adhering to the food, and can directly report the effect and efficacy of the function based on the function of improving the storage state of the food Thus, the user can easily use the functional device that improves the storage state, and the convenience of use can be further improved.

In addition, the refrigerator compartment door 1708 adopts one revolving door, but it is not limited to this, and multiple doors can also be used. The third storage box 1715 adopts a storage box drawn from a pull-out door, and when the door is opened, the fruits and vegetables are directly drawn to the side. The way the third storage box 1715 is stored.

The food storage of the present invention has: a storage box forming a storage room for storing food, a door for opening and closing the storage box, an ozone generator for generating ozone supplied to the storage room, and an agricultural chemical for promoting adhesion to food stored in the storage room, etc. Activation device for the decomposition of harmful substances.

Thereby, since it is low concentration ozone concentration which can be applied to a food storage, by activating decomposition of harmful substances, such as agricultural chemicals, harmful substances, such as agricultural chemicals, can be effectively decomposed. By decomposing harmful substances such as pesticides with low concentration of ozone, it is possible to provide food with higher safety for users.

In addition, the activation device of the food storage of the present invention activates the ecological defense reaction of the fruits and vegetables themselves.

Thereby, release of the antioxidant substance released from the activated fruit and vegetables increases. In addition, the increased antioxidant substances promote the decomposition of harmful substances such as pesticides, and can be more efficiently decomposed. That is, it is possible to improve the efficiency of decomposition of pesticides by ozone.

Moreover, the activation device of the food storage of this invention is a light source which emits the light of the wavelength which releases the antioxidant substance of fruits and vegetables.

And, the intense part of the vibration of the pesticide molecule activated in this way can cut off the molecular part of the pesticide by ozone. That is, it is possible to improve the efficiency of decomposition of pesticides by ozone.

In addition, the pesticide used in the food storage of the present invention is chlorpyrifos, organophosphorus pesticides such as malathion or quinaphos, or pyrethroid pesticides such as permethrin.

Thereby, it is possible to effectively decompose the pesticide which is used in a large amount in food and has a high possibility of remaining in the food, and it is possible to provide food with higher safety to the user.

Moreover, the food storage of this invention has the cooling device which cools the temperature of a storage room to 4 degrees C or less.

Thereby, since the storage room becomes a low-temperature environment, the foodstuffs in the storage room can be preserved for a long period of time. On the other hand, if the temperature in the weak storage room becomes low, the activity of the pesticide becomes low, and it is difficult to decompose ozone by the pesticide. Decomposed by ozone.

In addition, the refrigerator of the present invention has: a heat-insulating box body having a plurality of heat-insulating partitions; a freezing temperature zone storage room maintained in a freezing temperature zone, and having a refrigeration evaporator for cooling the refrigeration temperature zone storage room and a freezing evaporator for cooling the freezing temperature zone storage room, An ozone generating device for generating ozone supplied to the storage room in the refrigerated temperature zone and an activation device for promoting the decomposition of pesticides are provided, and the lowermost storage room in the storage room in the refrigerated temperature zone has the highest ozone concentration.

Thereby, antimicrobial storage in storage rooms in the refrigerated temperature zone and antimicrobial preservation of food can be improved, and harmful substances such as pesticides adhering to food can be reduced, and food safety can be further improved.

In addition, by making the ozone concentration in the storage room at the bottom the highest, even if the ozone flows out of the refrigerator due to taking out and putting in the food, the high-concentration ozone can flow out quickly to the bottom, which can provide safety. More reliable cold storage.

Moreover, the refrigerator of this invention is equipped with the ozone generator in the storage room located in the lowest among the storage rooms in a refrigeration temperature zone.

Accordingly, by directly installing the ozone generator in the lowermost storage room, it is possible to reliably make the ozone concentration of the lowermost storage room among the storage rooms in the refrigeration temperature zone the highest.

In addition, in the refrigerator of the present invention, an ozone generating device is provided in the lowermost storage partition in the storage room in the refrigeration temperature zone.

Thus, by directly installing the ozone generator in the lowermost storage compartment among the storage rooms in the refrigerating temperature zone, the ozone concentration in the lowermost storage room among the storage rooms in the refrigerating temperature zone can be reliably made the highest.
