A kind of refrigerator adopting direct cooling and micro-frost technology

Abstract

The invention relates to a direct-cooling micro-frost technology adopted refrigerator which comprises a freezing door, a freezing chamber inner container, a refrigerator body and a compressor. A water vapor condensation and separation board made of glass or metal materials is arranged between the freezing door and a freezing chamber of the refrigerator body. The water vapor condensation and separation board and the refrigerator body are fixed to a sunken table of the freezing chamber inner container through separation board shafts on lateral plastic pieces. The water vapor condensation and separation board is connected with the refrigerator body in a manually-opened-and-closed mode. A separation board sealing sleeve is installed on the periphery of the water vapor condensation and separation board and erected on the sunken table of the freezing chamber inner container. An opening of the freezing chamber inner container is right opposite to the water vapor condensation and separation board. The area of the water vapor condensation and separation board is larger than the area of the opening of the freezing chamber inner container. The refrigerator has the advantages that after the direct-cooling micro-frost technology is adopted for the direct-cooling refrigerator, the frosting time of an evaporator of the refrigerator can be shortened, the thickness of a condensed frost layer can be reduced, the refrigerating efficiency of the refrigerator can be improved, energy consumption can be reduced, and meanwhile the defrosting frequency of the refrigerator can be reduced.

Description

technical field [0001] The invention relates to the field of refrigerators, and mainly relates to a refrigerator adopting direct cooling micro-frost technology. Background technique [0002] In the current household refrigerator industry, the refrigeration methods of refrigerators generally adopt two types: air-cooled circulation and direct cooling. The air-cooled cycle uses forced convection to transfer the cold energy of the evaporator to the stored food through the medium of wind. The direct cooling refrigerator uses natural convection to transfer the cold energy of the evaporator to the food. [0003] The air-cooling circulation process will condense the water vapor (water vapor) of the food on the evaporator along with the medium of the circulating air, forming frost flowers. As the frosting becomes more and more serious, it will block the gap of the evaporator for wind flow, thereby reducing the heat exchange efficiency of the air-cooling cycle. Therefore, air-coole...

AI Technical Summary

Problems solved by technology

[0006] 1. The stored food itself will generate water vapor (water vapor);

[0007] 2. During the use of the direct cooling refrigerator, water vapor (water vapor) in the outside air enters due to opening the door;

[0008] 3. Although the door of the direct-cooling refrigerator is closed during use, there is an impossible gap between the refrigerator door and the cabinet, and at the same time, after cooling, a vacuum will be formed to suck the outside air due to the temperature drop, so that the Ingress of water vapor (water vapor) in the air
