Refrigerator and its defrosting control method and device

Abstract

The present invention provides a refrigerator and a defrosting control method and device thereof. The method includes: when the defrosting control program is executed, acquiring the defrosting temperature; determining that the defrosting temperature does not reach a preset exit temperature, and acquiring the compartment temperature ; Determine the defrost control parameters corresponding to the defrost control program according to the defrost temperature and the compartment temperature; execute the defrost control program according to the control parameters, and obtain the corresponding real-time defrost temperature when the defrost control program is executed each time; determine the real-time defrost control program When the defrost temperature reaches the preset exit temperature, the defrost program is exited to complete the defrost. The defrosting control method of the present invention can select a corresponding defrosting scheme according to the defrosting temperature and the compartment temperature when a single defrosting is incomplete in the refrigerator, so as to ensure the complete defrosting of the evaporator and avoid the occurrence of multiple incomplete defrosting. , causing the heater to work for a long time, the tank and the air duct will be yellowed, deformed, and even cause the risk of safety accidents.

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
