Title:
METHOD AND DEVICE FOR SELF-CLEANING OF AIR CONDITIONER FILTER, AND AIR CONDITIONER INDOOR UNIT
Document Type and Number:
WIPO Patent Application WO/2023/056773
Kind Code:
A1
Abstract:
A method and device for self-cleaning of an air conditioner filter, and an air conditioner indoor unit. An air conditioner comprises a filter (12), and a rotation mechanism (13), which is controlled to drag the filter to turn over back and forth between an air inlet (111) and a heat exchanger. The method comprises: acquiring a pollutant adhesion amount; determining a target amount of movement of a filter (12) and a target rotation speed of an indoor fan (14) when the pollutant adhesion amount is greater than or equal to a set threshold; controlling a rotation mechanism (13) to rotate, so as to drag the filter (12) to move to a heat exchanger according to the target amount of movement; and adjusting the rotation speed of the indoor fan (14) to the target rotation speed, and adsorbing pollutants from the filter (12) to the heat exchanger. The target amount of movement of the filter (12) is determined according to a relationship between the pollutant adhesion amount and the set threshold, such that the rotation mechanism (13) drags, according to the target amount of movement, the filter (12) to move to turn over a dirty surface of the filter (12) to the heat exchanger, thereby improving the precision of the turning-over of the filter.
