Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a food storage for storing food at appropriate temperature and appropriate humidity.

BACKGROUND OF THE INVENTION Traditionally, various foods have been preserved by storing them.

Problems to be Solved by the Invention However, in the above example, the food stored in the 3'-inch food storage is not controlled for temperature, humidity, etc. exposed to certain conditions. In recent years, housing structures have become more airtight, making it easy for heat and moisture to build up in the kitchen, resulting in high temperature and humid conditions.In addition, temperature and humidity can drop significantly at night, causing fluctuations in temperature and humidity. Oxidation and loss of vitamin C occur during food storage, which is not uncommon.

This was not a good storage condition for foods, as moisture absorption and flavor deterioration were likely to occur. Furthermore, high-temperature vegetables such as sweet potatoes, and tropical fruits such as bananas and pineapple, which have recently become well-known, such as papaya and mango, are highly temperature-dependent, and can be stored at temperatures below 10"C in the refrigerator. Refrigerated storage causes low temperature damage and insufficient ripening, and since high humidity conditions are desirable, it has been difficult to find an appropriate storage location.

Furthermore, known refrigerated storage has the problem that preserved foods become too dry.

On the other hand, due to the unique characteristics of foods, it is difficult to store all foods in one place.If they are stored together in the same place, the unique flavor of the food may be lost due to the transfer of moisture, etc. There were also problems in that the materials migrated and caused mutual deterioration.

The present invention solves the above-mentioned conventional problems, and
Food oxidation, loss of vitamin C, moisture absorption.

A dry goods room that prevents deterioration of flavor and allows switching between a medium-temperature storage function that preserves food at an appropriate temperature and humidity and a well-known refrigeration function, and that separates dry goods with strong odors to prevent odors from transferring. The purpose of the present invention is to provide a food storage in which a deodorizing device consisting of a high-pressure generator, an ozone generator, a catalyst, a deodorizing blower, etc. is built into an air path component.

Means for Solving the Problems In order to solve the above-mentioned problems, the food storage of the present invention has a heat insulating box body with a first . Second. forming a third storage chamber;
The second storage chamber is equipped with a storage container equipped with a moisture-permeable membrane, the third storage chamber is equipped with a storage container with an open top, and the first storage chamber is equipped with a rotary type storage container. the door,
Second. The third storage chamber is provided with a pull-out door connected to the storage container. 687 A well-known refrigeration cycle, a blower for forcing air into each storage compartment, and a standard temperature range of each storage compartment to medium temperature (approximately 1°C to 1°C) are used.
8°C) and refrigeration (approximately 1 to 8°C); a dry goods room provided in the first storage room with a door that can be opened and closed; and a dry goods room provided in the cold air circulation path. It consists of a deodorizing device consisting of a high pressure generator, an ozone generator, a catalyst, a deodorizing blower, etc.

Function The present invention uses the above-described configuration to circulate air cooled by a cooler in each storage room using a blower, and to switch between medium temperature (approximately 10 to 18°C) and refrigeration (about 10 to 18 degrees Celsius) in each storage room by a controller that performs switching control. It is possible to maintain the temperature by switching control between the temperature range (approximately 1 to 8 degrees Celsius). In addition, the humidifying and dehumidifying effects of the cooler caused by the ○N10FF operation of the compressor make it possible to maintain the appropriate humidity (approximately 30 to 50% RH) of the dry goods. Furthermore, when stored at medium temperatures (approximately 10 to 18° C.), the temperature difference with the outside air temperature is smaller than when stored in a refrigerator, so dew condensation can be suppressed when dry goods, etc. that dislike moisture are taken out.

In addition, a dry goods room with a door that can be opened and closed is provided in the first storage room, and a deodorizing device consisting of a high pressure generator, an ozone generator, a catalyst, a deodorizing air blower m, etc. is installed on the upper right side of the air path component. Since they are internally related, it is possible to separate dry foods with strong odors, deodorize and remove the strong odors of dry foods with strong odors, and at the same time, to prevent the transfer of odors.

In addition, in the storage container in the second storage chamber, water vapor generated by the fish spraying or breathing action of the fruits and vegetables to be stored is self-controlled by a moisture-permeable membrane to prevent drying.

Second. 21 is a blower for forcing air into each of the third storage compartments 8, 9, and 10, and 21 is the cooler 19;
A temperature sensing part is provided on the lee side of
This is a controller (hereinafter referred to as a thermostat) that switches and controls between (8°C) and refrigeration (approximately 1 to 8°C). Further, 22 is a discharge air passage leading into the first storage chamber 8, and 23 is a discharge air passage leading into the second storage chamber 8.
a discharge air passage leading into the storage chamber 9 and the third storage chamber 1°;
241d A return air passage 241d provided at the back surface of the lower part of the first storage chamber 8 and leading to the cooler 19; This is a return air path leading to the cooler 19. Reference numeral 26 denotes an operating member (hereinafter referred to as thermo dial) for switching the thermostat 21 between medium temperature (approximately 10 to 18 degrees Celsius) and refrigeration (approximately 1 to 8 degrees Celsius).

2γ is a dry goods room provided in the upper part of the first storage chamber 8, and has a substantially sealed structure consisting of an inner box 3, an air passage forming member 28, a dry goods shelf 29, and a dry goods door 3o which can be opened and closed.

Reference numeral 31 is a deodorizing device, and the structure 9 of the discharge air passage 22 is located on the upper right side of the air passage forming member 28 located at the rear of the dry goods room 27, which has a door 30 that can be opened and closed in the first storage room 8. It is built in like this. The deodorizing device 31 has a deodorized cold air suction port 32 from the dry matter chamber 27 and a deodorized cold air discharge port 33 to the dry matter chamber 27, and a high pressure generator 34, an ozone generator 36, and a catalyst 36 from the deodorized cold air suction port 32. The deodorizing blower 37, the fan 38, and the deodorizing cold air outlet 33 are arranged in communication so that convection occurs in this order.

The high voltage generator 34 and the ozone generator 35 are connected in parallel to a power source via a relay 39. The deodorizing blower 37 is also connected in parallel to the power source via a relay 39, similar to the high pressure generator 34 and the ozone generator 36. When the power is turned on, the excitation coil of the relay 39 is energized to close the contacts. 40 is a driver circuit configured to send a signal to turn ON10FF the relay 39.

In this configuration, the air cooled by the cooler 19 is circulated by the blower 20, cools the first storage chamber 8 through the discharge air passage 22, is returned to the cooler 19 through the return air passage 24, and is returned to the cooler 19 through the return air passage 24. 23 through the second storage chamber 9. The third storage chamber 1o is cooled and returned to the cooler 19 through the air passage 25.

On the other hand, by setting the thermostat 21 to medium temperature with the thermo dial 26, the compressor 18 and the blower 20 can be turned on/off.
The temperature inside the first, second, and third storage chambers 8, 9, and 10 is maintained at medium temperature (approximately 10 to 18°C), and the humidifying action of the cooler 19 is maintained by the 0N10FF operation of the compressor 18. The dehumidifying action maintains the appropriate humidity of dry goods (approx. RH 30-50%). For this reason, stored foods are not exposed to high temperature conditions, and oxidation, loss of vitamin C, and flavor deterioration are suppressed, making it possible to preserve them until the very end. By storing fruits and vegetables that are not suitable for the surface and require high humidity conditions in the storage container 11 of the second storage room 9, water vapor generated by the evaporation or respiration of the stored items can be absorbed by the moisture permeable membrane. Since the high humidity condition is controlled by the lid 13, good storage can be achieved. On the other hand, the first storage room 8. Third storage room 1
0 is maintained under dry conditions, which prevents oxidation, moisture absorption, and deterioration of flavor of stored foods.It also has the effect of preventing transferred odors caused by moisture transfer, making it ideal for storing various foods in the same place. It is possible to store it.

Furthermore, unlike low-temperature storage, refrigeration at 10"C or lower has a small relationship with the outside temperature, so condensation on the food that is pressed when taking out the stored food or opening/closing the door is suppressed, and the food does not get spoiled.

Furthermore, food that requires drying is stored in the first storage chamber 8 on the upper shelf, but since most of the food items are generally light, the user's convenience is not affected even if the food is on the upper shelf, and the door is a revolving door 16. It is also convenient for storing and taking out food.

The dry goods compartment 27 provided in the upper part of the first storage chamber 8 has a substantially airtight structure consisting of an inner box 3, an air passage component 28, a dry goods shelf 29, and a dry goods door 30 that can be opened and closed, so it has a strong odor. Dry goods can be stored in sections, and a deodorizing device 31 is installed in the discharge air passage on the upper right side of the air passage forming member 28 located behind the dry goods room 27 which is provided with a door 30 that can be opened and closed in the first storage room 8. 22 so as not to interfere with the structure of the deodorizing cold air suction port 32 , the high pressure generator 34 , the ozone generator 35 , the catalyst 36 , the deodorizing blower 37 , the fan 38 , and the deodorizing cold air discharge port 33 are connected so that convection occurs in this order. When the power is turned on, the excitation coil of the relay 39 is energized and the contacts are closed.
Electricity is supplied to the high-pressure generator 34, ozone generator 36, and deodorizing blower 3, so when the temperature is set to medium, the ozone deodorizing effect deodorizes and removes strong odors from dry goods in the dry goods compartment 27, and at the same time eliminates the smell of dry goods. It can prevent odors from transferring to other stored items, and it can deodorize and remove odors from pickles etc. when refrigerated, and also prevent odors from pickles from transferring to other stored items. can. ! Since the deodorizing device 31 is built into the upper right side of the air passage forming member 28, the effective internal volume does not decrease. In addition, many of the high-temperature vegetables and tropical fruits stored in the second storage chamber 9 in the middle tier, and the drinks and seasonings stored in the third storage chamber 10 in the lower tier, are relatively heavy foods. Since the storage chambers are arranged at low positions in the middle and lower tiers and the doors have drawer holes n16 and 17, the user's usability is not impaired.

On the other hand, thermostat 211 with thermodia/L/26
3. By setting the unit to refrigeration, the compressor 18 and blower 20 are set to 0N1.
0FF control, each of the first, second and third storage chambers 8, 9.
The inside of the chamber 10 is kept refrigerated (approximately 1 to 8° C.) and maintained at an appropriate humidity (approximately 30 to 60% RH) by the humidifying and dehumidifying effects of the cooler 19 caused by the 0N10FF operation of the compressor 18. Therefore, it is well known that refrigerated storage prevents over-drying first and second.

Food preservation in each of the third storage compartments 8, 9, 10 is improved.

Effects of the Invention As is clear from the above explanation, according to the present invention, the following effects can be obtained.

When setting medium temperature (1) By maintaining the temperature in each storage room at approximately 10 to 18 degrees Celsius, oxidation and vitamin C are promoted by high temperature conditions.
Loss of food and flavor deterioration are reduced, food can be stored for a long time in good condition, and the temperature difference with the outside temperature is reduced, so condensation and moisture absorption on food is suppressed when taking food out or opening/closing the door. .

4 (odor) The humidity in the first and third storage chambers is approximately RH30-6.
By maintaining the dry condition at 0%, food oxidation,
Moisture absorption, flavor comparison, etc. can be prevented.

By maintaining the inside of the first and third storage chambers under dry conditions, the transfer of odors between foods is reduced, and various foods can be stored in the same place, making inventory management easier.

(→ Even for high-temperature vegetables and tropical fruits that would cause low-temperature damage or insufficient ripening if stored in the vegetable compartment of a conventional refrigerator, they should be kept at a high humidity of 10 to 18°C in the second storage compartment using a moisture-permeable membrane. This allows for good storage.

(Light foods that require zero drying can be stored in the upper shelf with a revolving door, while other bulk items such as fruits and vegetables, drinks, and seasonings can be stored in the middle and lower shelves with a pull-out door. Food can be conveniently stored and taken out without sacrificing usability.

(The dry goods room installed in the upper part of the first storage room has a nearly sealed structure consisting of an inner box, air path components, dry goods shelves, and a dry goods door that can be opened and closed, and a high-pressure generator and an ozone generator. A deodorizing device consisting of a container, a catalyst, a deodorizing blower, etc. is built into the upper right side of the air path component, so dry goods with strong odors can be stored in compartments when the temperature is set to medium. At the same time, it is possible to deodorize and remove the odor of the dried goods, and also to prevent the odor of the dried goods from being transferred to other stored items, thereby preventing a decrease in the effective internal volume.

At the time of refrigeration setting, the temperature in each storage room can be maintained at about 1 to 8 degrees Celsius, and the humidity in each storage room can be maintained at about RH30 to 60%, so the humidity at the time of known refrigeration storage is about RHes to 1.
It can prevent over-drying by 6% and improve the shelf life of food.It also deodorizes and removes the smell of pickles and prevents the smell of pickles from being transferred to other stored items. be able to.
