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 defrost...

Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0027] figure 1 It is a structural schematic diagram of the defrosting system provided by the specific embodiment of the present invention. Such as figure 1 As shown, this scheme starts from various aspects of design to form an efficient and reliable defrosting technology. The defrosting system includes an evaporator body 1 and a pre-cooling evaporator 2 arranged at the bottom of the evaporator body 1 for cooling and dehumidifying the high-temperature and high-humidity air returning from the return air outlet. The pre-cooling evaporator 2 One end communicates with the air return port, and the other end communicates with the main body 1 of the evaporator.

[0028] In the air-cooled refrigerator with the defrosting system of the present invention, the high-temperature and high-humidity air returned...

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...
