It consists of the storage chamber 30 enclosed by the pipe | tube 32 and the heat insulating material, and the door 20 fixed by the hinge which covers the outer side of the said outer case 10.

In the machine room 40, a compressor 41 for compressing a refrigerant, a condenser 42 connected by a pipe to a discharge side of the compressor 41, a blower 43 and a kimchi refrigerator for supplying air to the condenser 42 are provided. The control unit of the microcomputer 44 is configured, the condenser 42 is connected to the expansion valve, the expansion valve is connected to the evaporation tube 32 surrounding the outside of the storage chamber (30).

Referring to the operation of the kimchi storage, the compressor 41 is operated to compress the refrigerant to a high temperature and high pressure, and then send it to the condenser 42, and the refrigerant moved into the condenser 42 is sucked by the blower 43 to the outside. In the process of heat exchange with air, it is converted into a liquid state, and the liquid refrigerant is converted into a gas state of low temperature and low pressure while passing through an expansion valve.

The low-temperature and low-pressure gas passes through the evaporation tube 32 to absorb heat from the storage chamber 30. In this process, the air in the storage chamber 30 is cooled to maintain a low temperature.

As shown in FIG. 2, the door 20 of the conventional kimchi storage is in contact with the upper end of the outer case 10 at the upper part of the storage compartment 30 to form a sealed structure, and the outer case 10 is the storage compartment 30. At the top of the step forming the step portion 50, the end of the inner case 31 is coupled to the inside of the outer case (10).

Here, the inside of the door 20 is formed of a non-metallic material, the outer case 10 is made of a plastic material forming a contact portion and the step portion 50 of the door 20, the door 20 and Since both the outer case 10 has a low thermal conductivity, a cold air transfer effect is lowered below the door 20, that is, above the storage compartment 30.

As described above, in the conventional kimchi storage room, the inside of the door is formed of a non-metallic material having a low thermal conductivity, and since the cold air cannot be transmitted because it is not in contact with the step of the storage room, the kimchi is easily overheated and stored for a long time. Had a difficult problem.

As described above, the problem that the cold air is not transferred from the upper part of the kimchi storage room has a problem in that the door of the kimchi storage is made of a material that does not transmit heat, and in order to solve this problem, a material having good thermal conductivity It is necessary to configure the inner cover of the furnace door to be in contact with the storage compartment inner case to enable heat transfer.

Accordingly, an object of the present invention is to improve the door structure of the kimchi storage to facilitate the transfer of cold air between the storage compartment and the door, to maintain the low temperature in the lower part of the door to suppress over-maturation during kimchi storage and long-term storage have.
