Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner filter cleaning, in particular to an air conditioner filter self-cleaning mechanism. Background Art

[0002] An air conditioner is an air conditioner that adjusts temperature and humidity. The air conditioner includes an indoor unit and an outdoor unit. The outdoor unit is set outdoors. Its main function is to bring in external air and discharge internal hot air. In order to ensure the quality of the air, a filter is usually installed in the air conditioner to filter the air and reduce the amount of dust that enters the air conditioner. During the use of the filter, it is generally necessary to use a cleaning mechanism to clean the dust adsorbed on the filter, thereby ensuring the normal use of the filter and improving the air filtering effect.

[0003] In a Chinese patent with publication number CN215675509U, a self-cleaning mechanism for a deodorizing air-conditioning unit is disclosed, in which an electric push rod pushes a connecting rod at the bottom end to move downward, and the connecting rod pushes a first movable plate and a second movable plate at both ends to move downward. During the downward movement of the first movable plate, a first card block in a first card slot is driven to move downward, and then the first card block drives a filter brush to move downward and automatically rubs the filter to clean dust and foreign matter. However, in actual use, the above-mentioned cleaning mechanism generally realizes reciprocating cleaning of the filter through the friction between the filter brush and the filter. However, the filter is prone to deformation and relaxation during long-term use, and there is a gap between the deformed filter and the filter brush, so that the filter brush and the filter cannot be cleaned in time, affecting the practicality of the cleaning mechanism.
