Description

  The present invention relates to a refrigerator provided with a storage room maintained at high humidity.

  Factors that affect the decline in freshness of vegetables include temperature, humidity, environmental gas, microorganisms, and light. Vegetables are living creatures that are breathing and transpiration, and in order to maintain freshness, it is necessary to suppress respiration and transpiration. Except for some vegetables, such as those that cause chilling disorders, respiration is suppressed at low temperatures, and transpiration can be prevented by high humidity. In recent years, refrigerators for home use have been designed to preserve vegetables, and are equipped with sealed vegetable containers that are controlled to cool vegetables to an appropriate temperature and to increase the humidity in the cabinet to suppress transpiration of vegetables. Yes. In addition, as a means for increasing the humidity in the cabinet, there is also a means that uses a means for spraying mist.

  Conventionally, as a refrigerator equipped with this kind of mist spraying function, there is a refrigerator that suppresses transpiration of vegetables by generating and spraying mist with an ultrasonic humidifier when the vegetable compartment is low in humidity (for example, , See Patent Document 1).

  19 and 20 show a conventional refrigerator provided with the ultrasonic humidifier described in Patent Document 1. FIG. As shown in FIGS. 19 and 20, the vegetable compartment 1 is provided at the lower part of the main body case 3 of the refrigerator main body 2, and its front opening is closed by a drawer door 4 that can be freely opened and closed. The vegetable compartment 1 is partitioned by a partition plate 5 from the refrigerator compartment (not shown) above it.

  A fixed hanger 6 is fixed to the inner surface of the drawer door 4, and a vegetable case 7 for storing food such as vegetables is mounted on the fixed hanger 6. The top opening of the vegetable case 7 is sealed with a lid 8. A thawing chamber 9 is provided inside the vegetable case 7, and the thawing chamber 9 is provided with an ultrasonic humidifier 10.

  The ultrasonic humidifier 10 is provided with a mist outlet 11, a water storage container 12, a humidity sensor 13, and a hose receiver 14. The water storage container 12 is connected to a defrost water hose 15 by a hose receiver 14. The defrost water hose 15 is provided with a purification filter 16 for purifying the defrost water at a part thereof.

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

  The cooling air cooled by a heat exchanger (not shown) flows through the outer surface of the vegetable case 7 and the lid 8 so that the vegetable case 7 is cooled and the food stored therein is cooled. Further, the defrost water generated from the cooler during the cooling operation is purified by the purification filter 16 when passing through the defrost water hose 15 and supplied to the water storage container 12 of the ultrasonic humidifier 10.

  Next, when the humidity sensor 13 detects that the internal humidity is 80% or less, the ultrasonic humidifier 10 starts humidification, and the atmosphere in the vegetable case 7 is moderate for keeping the vegetables and the like fresh. The humidity can be adjusted.

  On the other hand, when the humidity sensor 13 detects that the internal humidity is 90% or more, the ultrasonic humidifier 10 stops the humidification and prevents the vegetable case 7 from becoming excessively humid.

By these operations, the vegetable case 7 can be quickly humidified, and the inside of the vegetable case 7 is always at a high humidity, and the transpiration action of vegetables and the like can be suppressed and the freshness can be maintained.

  However, in the above conventional configuration, there is only one mist outlet 11 and the mist can be ejected only by aiming at the gap between the lid 8 and the thawing chamber 9 in FIG. In the case 7, the concentration of mist particles is not uniformly distributed, and variation occurs depending on the location. As a result, the freshness varies depending on the location of the vegetables stored in the vegetable case 7. In particular, the lower part of the thawing chamber 9 is a blind spot from the mist ejection direction, which is the worst place. Furthermore, when a large amount of vegetables are stored in the vegetable case 7, the gap between the lid 8 and the thawing chamber 9 is blocked, and it becomes difficult to spray mist over the entire vegetable case 7.

  In order to solve these problems, it is sufficient to increase the spray amount of mist sufficiently. However, if the spray amount of mist increases, condensation occurs in the vegetable case 7 and condensed water accumulates at the bottom. Another problem occurs. Excess water in the vegetable case 7 promotes damage to the stored vegetables, which is not preferable from the viewpoint of vegetable preservation.

Further, a diffusing unit 27 is disposed in the vicinity of and above the discharge port 28. In the present embodiment, an air convection blower is used as the diffusing means 27, but the diffusing means is a concept including various functional parts and structures that will eventually have a diffusing function. The present invention is not limited to the form, and various modifications can be made.

  The mist circulation means 30 is constituted by the circulation air passage 25, the circulation duct 24 constituting the circulation air passage 25, the air blowing means 25a, the discharge port 28 and the suction port 29 provided in the circulation duct 24, and the diffusion means 27. It is configured. The selection means 31 for selecting the particle diameter of the mist is composed of a diffusion means 27 and a spray means 26.

  A drain 32 for discharging excess water from the circulation air passage 25 to the outside of the storage chamber 18 is provided below the spraying means 26.

  Temperature sensors 33 and 34 are provided on the top surface of the storage chamber 18 and the bottom of the circulation duct 24, respectively.

  The door 21 is provided with a pair of left and right plate-like slide rails 35 extending into the storage chamber 18, and a food storage container 36 is placed on the door 21. The door 21 is opened and closed by pulling it horizontally along the direction in which the slide rail 35 is movable. The discharge port 28 is located higher than the outer edge of the food storage container 36 so that mist always enters the food storage container 36. In addition, a plurality of vent holes 37 are provided on the bottom surface of the food container 36.

  A heater 38 for heating the lower part of the storage chamber 18 is provided at the bottom of the circulation duct 24.

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

  Above and below the storage chamber 18, storage chambers 19 and 20 set in a temperature range lower than that of the storage chamber 18 are arranged, and the storage chamber 18 is naturally cooled by these storage chambers 19 and 20.

  When the door 21 is pulled out horizontally in the front direction, vegetables are put in the food container 36 and then the door 21 is closed, the door opening detection means (not shown) detects the closed state, and the spray means 26 starts spraying mist. To do. The sprayed mist rises upward by the air blowing means 25a disposed above the spraying means 26, passes through the discharge port 28, and is diffused and sprayed into the storage chamber 18 by the diffusion means 27.

  As the spraying means 26, for example, a means for atomizing and spraying water with ultrasonic waves may be used, and the particle diameter of the sprayed mist is distributed as shown in FIG. When the mist is to be diffused uniformly in the storage chamber 18, it is better that the mist particles stay in the storage chamber 18 for as long as possible, and fine particles are more advantageous. In FIG. 5, it can be said that, for example, water particles having a particle diameter X or less may be taken out and sprayed by diffusion.

  As the spray means 26, it is conceivable to use not only the ultrasonic method but also an electrostatic atomization method, a pump method, and the like.

  As for the mist sprayed by the spraying means 26, those having a particle diameter of X or more fall downward due to their own weight, and those having a relatively light particle diameter of X or less rise by the blowing means 25a. . Thereby, it becomes possible to selectively take out mist particles having a certain diameter or less. The target particle size X can be set freely and can be adjusted according to the operating degree of the spraying means 26, the operating degree of the blowing means 25a and the diffusing means 27, and the distance between the spraying means 26 and the blowing means 25a. Is possible. This operating degree refers to, for example, the vibration frequency when an ultrasonic generator is used for the spraying means 26 and the fan rotation speed when a blowing fan is used for the blowing means 25a and the diffusing means 27. Further, the mist having a particle diameter X or more dropped downward is discharged from the drain 32 to the outside of the storage chamber 18.

  Since the discharge port 28 is above the food storage container 36, the mist sprayed in the storage chamber 18 pours from above the food storage container 36, that is, from above the stored vegetables.

  Further, the mist diffused and sprayed by the diffusing means 27 provided on the upper portion of the discharge port 28 falls downward through the gap between the food container 36 and the vegetable or between the vegetable and the vegetable. At this time, the distance between the end portions of the plurality of discharge ports 28 is set to a size equivalent to the lateral width of the food storage container 36, and distribution variation of the mist concentration in the lateral direction can be suppressed.

  A plurality of vents 37 are provided on the bottom surface of the food storage container 36, and mist in the food storage container 36 passes through the vent 37 to the lower part of the storage chamber 18. Therefore, it does not stop in the food storage container 36, and water does not accumulate at the bottom. In the present embodiment, the vent 37 is provided on the bottom surface, but it may be provided on the side wall surface of the food storage container 36 as well as the bottom surface.

  The mist that has passed through the vent 37 returns to the circulation air passage 25 from the suction port 29, and a part thereof is sprayed again into the storage chamber 18. Some of the water droplets are large and are discharged from the drain 32 to the outside of the storage chamber 18. In order to perform this drainage efficiently, the lower part of the circulation air passage 25 is inclined toward the drain 32 as shown in FIG. If the suction port 29 of the circulation duct 24 and the ventilation port 37 of the food container 36 are opened at substantially the same position, the circulation resistance is low and the efficiency is high.

  As means for optimizing the mist distribution in the food container 36 and making it the most uniform, adjustment of the operating degree of the diffusion means 27 and adjustment of the positions and areas of the discharge port 28, the vent 37, and the suction port 29 are possible. It is good to do.

  In addition, although it is necessary to supply water continuously to the spraying means 26, a water supply tank is provided for this, and the method of replenishing water regularly and the water collection structure which collects and collect | recovers moisture in a storage chamber are taken. Good. Furthermore, a water supply tank and a water recovery structure may be used in combination.

  When the door 21 is not opened or closed at night or the like, the degree of decrease in humidity is gradual, and the mist spraying may be stopped for a certain period of time. In this case, when it is determined by the door opening detection means (not shown) that a certain time has elapsed since the door was closed, the operation of the spraying means 26 and the operation of the blower means 25a and the diffusing means 27 are stopped and simultaneously provided in the circulation duct 24. The heater 38 is energized to heat the lower part of the storage chamber 18. The heating control of the heater 38 is controlled so that the temperature difference between the temperature sensor 33 provided on the top surface of the storage chamber 18 and the temperature sensor 34 provided at the bottom of the circulation duct 24 becomes a certain value. As a result, there is a temperature difference between the upper part and the lower part of the storage chamber 18, and natural convection of air is promoted. The heater 38 may be a heater that generates heat substantially uniformly over a wide range, and may be a linear heater or a sheet heater. The means for providing the temperature difference is not limited to the heater, and the temperature of the storage chamber 19 may be controlled lower than that of the storage chamber 20.

The door 21 is opened and closed by pulling it horizontally along the direction in which the slide rail 35 is movable. The discharge port 28 is located higher than the outer edge of the food storage container 36 so that mist always enters the food storage container 36. In addition, a plurality of vent holes 37 are provided on the bottom surface of the food container 36.

  A heater 38 for heating the lower part of the storage chamber 18 is provided at the bottom of the circulation duct 24.

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

  Above and below the storage chamber 18, storage chambers 19 and 20 set in a temperature range lower than that of the storage chamber 18 are arranged, and the storage chamber 18 is naturally cooled by these storage chambers 19 and 20.

  When the door 21 is pulled out horizontally in the front direction, vegetables are put in the food container 36 and then the door 21 is closed, the door opening detection means (not shown) detects the closed state, and the spray means 26 starts spraying mist. To do. The sprayed mist rises upward by the air blowing means 25a disposed above the spraying means 26, and is stored in the storage chamber 18 by the discharge port 828 provided in the extending portion 39 of the circulation duct 24 disposed on the top surface. It is sprayed by diffusion. The mist sprayed from the plurality of discharge ports 828 is supplied to the vegetables stored in the food storage container 36 more uniformly, and the freshness of the vegetables can be maintained with a small spray amount.

  As the spraying means 26, for example, water sprayed by atomizing water by an ultrasonic vibration method is used. When the mist is to be diffused uniformly in the storage chamber 18, it is better that the mist particles stay in the storage chamber 18 for as long as possible, and fine particles are more advantageous.

  As the spraying means 26, it is possible to use not only the ultrasonic vibration method but also an electrostatic atomization method, a pump method, a water crushing method using centrifugal force, and the like.

  As for the mist sprayed by the spraying means 26, those having a particle diameter of X or more fall downward due to their own weight, and those having a relatively light particle diameter of X or less rise by the blowing means 25a. . Thereby, it becomes possible to selectively take out mist particles having a certain diameter or less. The target particle diameter X can be freely set and can be adjusted by the operating degree of the spraying means 26, the air blowing means 25a, the distance between the spraying means 26 and the air blowing means 25a, and the like. The degree of operation refers to, for example, vibration frequency control / duty operation when an ultrasonic vibration device is used for the spraying means 26 and the rotation speed of the blowing means 25a. Further, the mist having a particle diameter X or more dropped downward is discharged from the drain 32 to the outside of the storage chamber 18.

  Since the discharge port 28 is above the food storage container 36, the mist sprayed in the storage chamber 18 pours from above the food storage container 36, that is, from above the stored vegetables.

  Further, the mist diffused and sprayed from the discharge port 828 falls downward through the gap between the food container 36 and the vegetable or between the vegetable and the vegetable. At this time, the distance between the end portions of the plurality of discharge ports 828 is set to a length substantially equal to the size of the food storage container 36, and the mist concentration distribution variation can be suppressed. Further, in order to limit and concentrate the position where the mist is sprayed, the opening portion can be limited by the closing member 60 in which the plurality of discharge ports 828 are installed so as to be closed. In addition, the bottom of the extending portion 39 of the circulation duct 24 disposed on the top surface is inclined toward the rear surface of the refrigerator, stays without being sprayed from the plurality of discharge ports 828, and aggregates on the bottom of the inner surface of the extending portion 39. The condensed water thus collected can be collected and reused as supply water to the spray means 26. Further, an irradiation means 61 is installed around the extending portion 39 of the circulation duct 24 disposed on the top surface. For example, in the case of white light, the irradiation means 61 has an effect as internal lighting of the storage room 18, and in the case of red light, it functions to increase the nutrients of the stored food. Furthermore, in the case of blue light, since there is a function of opening the pores of the stored vegetables, the vegetables absorb water from the sprayed mist, and the freshness of the vegetables can be improved.

  A plurality of vents 37 are provided on the bottom surface of the food storage container 36, and mist in the food storage container 36 passes through the vent 37 to the lower part of the storage chamber 18. Therefore, it does not stop in the food storage container 36, and water does not accumulate at the bottom. In the present embodiment, the vent 37 is provided on the bottom surface, but it may be provided on the side wall surface of the food storage container 36 as well as the bottom surface.

  The mist that has passed through the vent 37 returns to the circulation air passage 25 from the suction port 29, and a part thereof is sprayed again into the storage chamber 18. Some of the water droplets are large and are discharged from the drain 32 to the outside of the storage chamber 18. In order to efficiently perform this drainage, the lower part of the circulation air passage 25 is inclined toward the drain 32 as shown in FIG. If the suction port 29 of the circulation duct 24 and the ventilation port 37 of the food container 36 are opened at substantially the same position, the circulation resistance is low and the efficiency is high.

  As a means for optimizing and making the mist distribution in the food storage container 36 most uniform, it is preferable to adjust the positions and areas of the discharge port 828, the vent 37, and the suction port 29.
