Defrosting system and refrigerator with same

Abstract

The invention relates to the field of refrigeration defrosting of refrigerators, in particular to a defrosting system and a refrigerator with the defrosting system. The defrosting system comprises an evaporator body and a precooling evaporator, wherein the precooling evaporator is arranged at the bottom of the evaporator body and is used for cooling and dehumidifying high-temperature high-humidity air returning from a return air inlet. One end of the precooling evaporator is communicated with the return air inlet. The other end of the precooling evaporator is communicated with the evaporator body. According to the defrosting system, the precooling evaporator is arranged at the bottom of the evaporator body, after the high-temperature high-humidity air returning from the return air inlet is cooled and dehumidified through the precooling evaporator, cooling and heat exchange are conducted on the cooled and dehumidified air through the evaporator body, and therefore part of frost condenses on the precooling evaporator; in this way, the amount of frost on the evaporator body is obviously reduced, frost is even, and the heat exchange efficiency of the evaporator body is effectively improved.

Description

technical field [0001] The invention relates to the field of refrigeration and defrosting of refrigerators, in particular to a defrosting system and a refrigerator provided with the defrosting system. Background technique [0002] The air-cooled refrigerator is also called frost-free refrigerator. The air-cooled refrigerator is equipped with an evaporator and a set of air circulation components. When working, the fan motor will circulate the air in the box cooled by the evaporator to achieve the purpose of cooling. . Due to the cold air flow blown in, it will not cause frost to absorb moisture from the stored food. However, the air-cooled refrigerator only has no frost on the surface of the inner wall, and the surface of the evaporator is still frosted. [0003] At present, with more and more air-cooled refrigerators on the market, the application of air-cooled technology is becoming more and more extensive, among which the defrosting technology for evaporators is particul...

AI Technical Summary

Problems solved by technology

This kind of defrosting method has the problem of defrosting when defrosting is not needed, but it may not be able to defrost in time when defrosting is required, and it will consume too much power

The other is intelligent defrosting. This kind of defrosting technology is more complex and combined with the actual use conditions of the refrigerator to defrost on demand, but this kind of defrosting method cannot fully guarantee the sufficiency of defrosting

[0005] In view of the above problems, there is an urgent need for a defrosting system that reduces the amount of frosting, so as to solve the problems in the prior art that the defrosting consumes more power, the sufficiency of defrosting cannot be fully guaranteed, and the heat exchange efficiency of the evaporator is low. The problem
