Document Type and Number:
WIPO Patent Application WO/2024/060699
Kind Code:
A1
Abstract:
The present application relates to the technical field of intelligent household appliances. Disclosed is a method for controlling a dehumidifier. The method comprises: determining an evaporator tube temperature change value △Tinner tube, an inner ring temperature change value △Tinner ring and an air output temperature change value △Tair output between a power-on moment t0 of a dehumidifier and a moment ts after powering on; and according to △Tinner tube, △Tinner ring and △Tair output, determining whether there is a lack of refrigerants of the dehumidifier, and controlling the dehumidifier to execute a corresponding remedial strategy. In the method, whether there is a lack of refrigerants of a dehumidifier is determined according to an evaporator tube temperature change value, an inner ring temperature change value and an air output temperature change value between a power-on moment t0 of the dehumidifier and a moment ts after powering on, and a corresponding remedial strategy is executed, thereby being conducive to more intelligently and more accurately determining, according to an actual operation condition of the dehumidifier, whether there is a lack of refrigerants, avoiding untimely protection against a lack of refrigerants of a system, avoiding false protection performed when there is not a lack of refrigerants, and improving the degree of intelligence and the accuracy.
