Title:
REFRIGERATOR AND DEFROSTING CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/128944
Kind Code:
A1
Abstract:
A refrigerator and a defrosting control method thereof: on the basis of the surface temperature of an evaporator (300), adjusting the voltage applied to an electromagnetic defrosting apparatus (400); when the surface temperature of the evaporator rises by a certain temperature value, reducing the voltage applied to the electromagnetic defrosting apparatus (400) in order to reduce the power of the electromagnetic defrosting apparatus (400). When the frost on the surface of the evaporator (300) is thick and the temperature is low, making the electromagnetic defrosting apparatus (400) operate at a high power in order to increase the defrosting efficiency; when the frost on the surface of the evaporator (300) is relatively little and the temperature is high, making the electromagnetic defrosting apparatus (400) operate at a low power in order to prevent the surface temperature of the evaporator rising too quickly; defrosting efficiency is improved whilst ensuring that the surface temperature of the evaporator (300) rises normally and steadily, optimising the working process of the electromagnetic defrosting apparatus (400).
