Title:
REFRIGERATOR AND DEFROSTING CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/128943
Kind Code:
A1
Abstract:
Disclosed are a refrigerator and a defrosting control method therefor. The refrigerator comprises: a refrigeration circulation system composed of a compressor (100), an evaporator (300) and a condenser (200); an electromagnetic defrosting device (400) comprising a plurality of defrosting modules arranged in a height direction of the evaporator (300); and a temperature detection device (310) and a power detection module (410). The method comprises: adjusting the power of a corresponding defrosting module based on variations in a surface temperature of the evaporator (300) and the position of each defrosting module, and if the surface temperature of the evaporator (300) exceeds a pre-set temperature, appropriately reducing the power of each defrosting module, and respectively reducing the power of the plurality of defrosting modules based on the different positions of the plurality of defrosting modules, so as to prevent an overly-quick temperature rise of the evaporator (300) from affecting subsequent refrigerator refrigeration.
