Air-cooled refrigerator and defrosting method of same

Abstract

The invention relates to an air-cooled refrigerator, in particular to a defrosting device of the air-cooled refrigerator. The invention provides the air-cooled refrigerator with simpler and effective defrosting method and the defrosting method of same, wherein the air-cooled refrigerator is formed by improving the original components of the refrigerator. The air-cooled refrigerator comprises a CPU and an air channel, wherein the air channel is internally provided with a fan, the fan is connected with the CPU, the fan comprises a cold room fan and a refrigerating room fan, the cold room fan is set into a two-way fan, when the temperature of a cold room rises to the set temperature, the cold room fan starts to reverse so as to lead evaporator defrosting water vapour to be blown back into the cold room. The defrosting method can slow down the temperature rising in the cold room so as to prolong the downtime of a compressor, thereby reducing the starting ratio of the compressor; humid air is blown back to the cold room and a fruit and vegetable room, thereby ensuring the humidity in the cold room and the fruit and vegetable room, and being beneficial to keep fruit and vegetable fresh; meanwhile, because the temperature of gas in the cold room is higher, the frost layer on a refrigeration evaporator is effectively removed, and the purpose that the defrosting function of the evaporator fine adjusts the temperature of the cold room is achieved.

Description

technical field [0001] The invention relates to an air-cooled refrigerator, in particular to a defrosting device and a defrosting method for an air-cooled refrigerator. Background technique [0002] After the air-cooled refrigerator works for a period of time, because the water inside the box passes through the evaporator, a layer of frost forms on the surface of the evaporator, which reduces the evaporation effect of the evaporator. Therefore, after the evaporator of the air-cooled refrigerator has been working for a period of time, it must be defrosted to remove the frost layer on the surface of the evaporator in order to continue to ensure the evaporation effect of the evaporator. The air-cooled refrigerators in the prior art generally adopt the defrosting method of the heater. The heater not only takes up space and consumes electricity in the refrigerator, but also there may be flammable and explosive gases in the refrigerator, so it is more dangerous; The controller al...

AI Technical Summary

Problems solved by technology

The air-cooled refrigerators in the prior art generally adopt the defrosting method of the heater. The heater not only takes up space and consumes electricity in the refrigerator, but also there may be flammable and explosive gases in the refrigerator, so it is more dangerous; The controller also occupies the interface of the main control board in the refrigerator.
