Control method of air-cooled refrigerator and air-cooled refrigerator

Abstract

The invention discloses a control method of an air-cooled refrigerator and the air-cooled refrigerator. The control method comprises the following steps that whether the air-cooled refrigerator meetsa defrosting condition or not is judged in a refrigeration process of the air-cooled refrigerator; if the defrosting condition is met, a compressor of the air-cooled refrigerator is controlled to be shut down, meanwhile, a freezing fan of the air-cooled refrigerator is controlled to continue to operate, and whether the freezing fan meets the shutdown condition or not is judged in real time; and ifthe freezing fan meets the shutdown condition, the freezing fan is controlled to be shut down, the air-cooled refrigerator is controlled to enter a defrosting mode, and a defrosting device is startedfor defrosting. According to the control method of the air-cooled refrigerator, the shutdown of the freezing fan is controlled through judging the shutdown time of the freezing fan in real time, so that the air-cooled refrigerator makes full use of the residual cooling capacity of an evaporator, the situation of food deterioration caused by large temperature change of a freezing chamber due to defrosting is prevented, and it can also be ensured that the time needed for the air-cooled refrigerator to enter the refrigeration mode again and reach the freezing temperature is shortened.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a control method of an air-cooled refrigerator and the air-cooled refrigerator. Background technique [0002] It is pointed out in the related art that after the air-cooled refrigerator works in the cooling mode for a long time, serious frosting may occur on the evaporator located in the freezing room. Therefore, after the air-cooled refrigerator runs in the cooling mode for a period of time, it needs Control the air-cooled refrigerator to exit the cooling mode and turn on the defrosting device for defrosting. [0003] In the existing defrosting mode, after the air-cooled refrigerator is transferred from the cooling mode to the defrosting mode, it usually controls the compressor to stop, and controls the freezing fan to continue running for a fixed time to make full use of the remaining cooling capacity of the evaporator. The defrosting device is controlled to st...

Problems solved by technology

[0003] In the existing defrosting mode, after the air-cooled refrigerator is transferred from the cooling mode to the defrosting mode, it usually controls the compressor to stop, and controls the freezing fan to continue running for a fixed time to make full use of the remaining cooling capacity of the evaporator. The defrosting device is controlled to start defrosting after the refrigerating fan continues to run for a fixed time. This method of controlling the refrigerating fan to continue running for a fixed time mainly has the following problems: It is difficult to control the defrosting device of the air-cooled refrigerator to be put into operation accurately at the right time Defrost
