Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a food storage for storing food at a suitable humidity.

Conventional technology Conventionally, samples that require cooling for preservation are stored in the refrigerator, and other foods are stored in a food storage cabinet in the kitchen. .

Problems to be Solved by the Invention However, in the above example, the food stored in the food storage is not controlled in temperature and humidity, and is kept under the temperature and humidity conditions in the kitchen. There is. On the other hand, in recent years, housing structures have become more airtight, and heat and humidity are trapped in the kitchen, resulting in high temperature and high humidity conditions. This has led to oxidation, loss of vitamin C, moisture absorption, and deterioration of flavor during food storage. This was a concern and the storage conditions were not good for food. Also, due to the unique characteristics of foods, it is difficult to store all kinds of foods in one place, and if they are mixed together in the same place, the unique flavor of the food may be lost due to the movement of moisture, etc. There were also problems in that they migrated and caused mutual deterioration.

The present invention solves the above-mentioned conventional problems,
The purpose is to prevent food oxidation, loss of vitamin C, moisture absorption, deterioration of flavor, etc., and to provide a food storage facility that preserves food for a long time.

Means for Solving the Problems In order to solve the above problems, the food storage of the present invention includes a first dry storage chamber and a second storage chamber formed of a heat-insulating box body;
A storage container provided in a second storage chamber with an opening on one side and a lid made of a moisture permeable membrane that seals the opening surface, a refrigeration cycle for cooling these storage chambers, and a blower for forced ventilation; It is equipped with a temperature control device that maintains the temperature inside the storage chamber at 10 to 15°C.

Function The present invention uses the above-described configuration to circulate air cooled by a cooler in a food storage by a blower, and maintain the temperature inside the door at 10 to 15°C by a temperature control device. Moreover, the inside of the storage can be dried due to the dehumidifying effect of the cooler.

On the other hand, in a storage container provided in the second storage chamber that is open on one side and equipped with a lid made of a moisture-permeable membrane that seals the opening, water vapor generated from stored vegetables and fruits due to transpiration or respiration is removed. However, if the saturated humidity is higher than this, it will permeate through the moisture-permeable membrane of the lid, and the inside of the container will be maintained at an appropriate humidity without condensation on the inner surface of the container, making it possible to preserve vegetables, fruits, etc. for a long time.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 denotes the main body of the food storage, which is composed of an outer box 2, an inner box 3, and a heat insulating material 4 filled between these two boxes 2 and 3. Reference numeral 6 denotes a partition wall which defines a first storage chamber 6 at the upper part and a second storage chamber 7 at the lower part.
The front openings of the storage rooms 8 and 7 each have a door body 8 that can be opened and closed freely.
, 9 are provided. 1o is a storage container provided in the second storage chamber T, and is configured to have a substantially airtight structure with a lid 11 fixed to the storage chamber 7 side as the main part,
It is supported by the door body 9 and can be moved forward and backward to open and close.

The lid body 11 is made of a resin flat plate 1 having a large number of through holes.
2, a moisture permeable membrane 13 welded to one side of this flat plate 12,
It is constituted by a resin frame 14 adhered to the outer periphery of the flat plate 12. Then, the upper end of the opening surface of the container 1o and the lower end of the frame 14 of the lid 11 are fitted together to form a sealed state. Here, the moisture permeable membrane 13 will be explained.

The moisture permeable membrane 13 is made by laminating a silicon thin film 15 and a hydrophilic nylon fiber 15. The silicon thin film 15 has a thickness of about 10 μm to about 60 μm and is made up of mostly amorphous chain-like molecular aggregates. The aggregate of molecules of the shape completely blocks liquid, and has gas permeability due to the molecular spacing of 10 to 10'. In other words, water vapor, air,
If there is a difference in concentration between the inside and outside of the membrane, carbon dioxide gas will permeate through the membrane. Further, the reason for using the hydrophilic nylon fiber 15 is to prevent dew condensation.

1A is a compressor of the refrigeration cycle; 18 is a cooler; 19 is a blower for forcing the air cooled by the cooler 18 into the first and second storage chambers 6 and 7; 20.21 is the cooling unit; A duct 22 guides the cold air cooled by the container 18 to the first and second storage chambers 6.7 using the blower 19, and 22 is a duct that controls the temperature in the first and second storage chambers 6.7 to 10 to 10. 15
This is a temperature control device that maintains the temperature at °C.

The operation in this configuration will be explained. The cold air cooled by the cooler 18 is circulated by the blower 19 to cool the first and second storage chambers 6 and 7.

On the other hand, the compressor 17 and the blower 19 are controlled by the temperature control device 22.
The operation and stop of the storage chambers 6 and 7 are controlled and the temperature inside the first and second storage chambers 6 and 7 is maintained at 10 to 15°C. Therefore, stored foods are not exposed to high humidity conditions, reducing oxidation, loss of vitamin C, flavor deterioration, etc., and has the advantage of being able to better preserve vegetables and fruits, which can suffer from low-temperature damage in refrigeration. are doing.

Furthermore, since there is a smaller difference from room temperature compared to refrigeration, there is less chance of condensation occurring when food is taken out.

In addition, the dehumidifying effect of the cooler 18 dries the first storage chamber 6, preventing oxidation, moisture absorption, and flavor deterioration of the stored food.
Historically, it has the effect of preventing the transfer of odors caused by the transfer of moisture, etc., making it possible to store a variety of foods in the same place.

Furthermore, the second storage chamber 7 has a sealed structure, so that cold air does not directly enter into the storage container 10, and the inside of the storage container 10 is kept at high humidity due to moisture evaporated from stored vegetables, fruits, etc. dripping The moisture above the saturated humidity gradually permeates through the moisture permeable film 13 on the surface of the lid 11 to the side of the refrigerator compartment 4 where the humidity is low. Therefore, dew condensation often occurs on the inner surface of the lid 11 of the container 1o, and vegetables and fruits are not damaged due to falling water droplets or contact with water. In this way, vegetables, fruits, etc. can maintain their freshness for a long period of time without drying out and wilting.

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

(1) 10 which is said to be the ideal storage temperature for food stored at room temperature
By storing food at ~15°C, oxidation, loss of vitamin C, flavor deterioration, etc. that are promoted under high temperature conditions are reduced, and food can be stored in good condition for a long period of time. Also, 10~15°
Compared to refrigeration, medium temperature temperature C has the advantage that there is less chance of condensation occurring when food is served because the difference from room temperature is smaller.

(2) By keeping the inside of the storage room dry, food oxidation, moisture absorption, flavor deterioration, etc. can be prevented.

(3) By keeping the inside of the storage room dry, the transfer of odors between foods is reduced, and various foods can be stored in the same place, making inventory management easier.

(4) Even vegetables and fruits that frequently suffer from low-temperature damage when stored in conventional vegetable canes can be stored well by keeping them at 10 to 15°C and high humidity.

(5) When storing vegetables and fruits, the container is sealed with a lid equipped with a moisture-permeable membrane, so the inside of the container becomes highly humid due to water vapor from the transpiration of the vegetables and fruits, and excess moisture is absorbed by the moisture-permeable membrane. Moisture permeates through the surface, preventing condensation from forming inside the container, allowing vegetables and fruits to be stored for long periods of time without drying out or being damaged by water droplets.
