Refrigerator and defrosting control method and device thereof

Abstract

The invention provides a refrigerator and a defrosting control method and device thereof. The method comprises the following steps that 1, when the execution of a defrosting control program is completed, a defrosting temperature is acquired; 2, it is determined that the defrosting temperature does not reach a preset exit temperature, and a room temperature is obtained; 3, a defrosting control parameter corresponding to the defrosting control program is determined according to the defrosting temperature and the room temperature; 4, the defrosting control program is executed according to the control parameter, and a real-time defrosting temperature corresponding to each completion of execution of the defrosting control program is obtained; and 5, it is determined that the real-time defrosting temperature reaches the preset exit temperature, and the defrosting program is exited to complete defrosting. According to the defrosting control method, the corresponding defrosting scheme can be selected according to the defrosting temperature and the room temperature when the single defrosting of the refrigerator is incomplete, so that it is ensured that the defrosting of an evaporator is complete, incomplete defrosting multiple times is avoided, an oven liner and an air flue are prevented from being scaled and deformed due to long-time work of a heater, and even the risk of safety accidents is caused.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a defrosting control method of a refrigerator, a defrosting control device of a refrigerator, a refrigerator, an electronic device and a computer-readable storage medium. Background technique [0002] The defrosting control program of the current air-cooled refrigerator is mainly to execute the defrosting program when the defrosting condition is met after the refrigerator is refrigerated. Among them, when the defrosting sensor reaches the exit temperature or the defrosting time reaches the maximum allowable value, the defrosting heater Stop working, perform dripping action, let the defrosting water on the evaporator flow into the water receiving tray, so far the defrosting is over, and turn to normal refrigeration control. [0003] However, when the evaporator is heavily frosted, it is very likely that a single defrost (the longest single operation time allowed by th...

Problems solved by technology

[0003] However, when the evaporator is heavily frosted, it is very likely that a single defrost (the longest single operation time allowed by the heater) cannot remove the frost layer on the evaporator (the defrost sensor has not reached the exit temperature) , the refrigerator continues to refrigerate, and continues to defrost after reaching the defrosting condition, and the phenomenon of being unable to completely defrost occurs again. After repeating this many times, the tank and air duct will be yellowed, deformed, and even cause the risk of spontaneous combustion accidents of the refrigerator
