[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0018] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0019] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0020] Reference Figures 1 to 3, an air conditioner with an automatic filter cleaning function, comprises a casing 1, the casing 1 is provided with an air inlet end 2 and an air outlet end 3, a transmission chain controlled by a transmission motor is installed inside the casing 1, the outer side of the transmission chain is covered with a filter cloth 4, one side of the filter cloth 4 is in contact with the inner wall of the casing 1 at the position of the air outlet end 3; a water tank 5 is provided at the bottom of the casing 1, the lower end of the filter cloth 4 is immersed in the water tank 5, and a high-pressure nozzle 7 connected to a water pump 6 pipeline for flushing the filter cloth 4 is also installed in the casing 1. After the filter cloth 4 is transmitted into the water tank 5 by the transmission chain, the dust and other dirt on the filter cloth 4 are flushed through the high-pressure nozzle 7, so as to achieve the effect of automatic cleaning, and can be cleaned without stopping the machine, so as to achieve multiple uses, save costs, and do not need to rely on personnel to make judgments based on their own experience, so as to effectively improve the ventilation quality of the air conditioner.

[0021] The water tank 5 includes a sewage area 8 and a clean water area 9, and a filter screen 16 for filtering mud and sand is installed between the sewage area 8 and the clean water area 9 (the edge of the filter screen 16 is sealed with the inner side of the water tank 5 to prevent water from entering the clean water area 9 without passing through the filter screen 16), the water inlet end of the water pump 6 is installed in the clean water area 9, and the lower end of the filter cloth 4 is immersed in the sewage area 8. After the water in the sewage area 8 is filtered by the filter screen 16 (such as using activated carbon, filter cotton, etc., only used to filter mud and sand and other impurities with a certain volume of particles), it enters the clean water area 9, and then the water pump 6 is used to rinse the filter cloth 4 through the high-pressure nozzle 7. Sensors for detecting water turbidity are installed in both the sewage area 8 and the clean water area 9. When the turbidity of one side of the sewage area 8 and the clean water area 9 reaches a preset value, the water tank 5 is cleaned and the water is changed.

[0022] One side of the filter cloth 4 is the water inlet side entering the sewage area 8, and the other side is the water outlet side leaving the sewage area 8. The high-pressure nozzle 7 flushes the water outlet side. During the flushing process, the filter cloth 4 is soaked and then flushed to increase the water content of mud, dust, etc., to avoid a large amount of mud, dust being raised during the flushing process and attached to the air in the casing 1, affecting the purification and ventilation effects of the air conditioner.

[0023] A drying area 10 is provided above the water outlet side in the casing 1, and a drying device 11 is installed in the drying area 10 for drying the part that has been rinsed. After the part of the filter cloth is dried, the transmission chain is driven again to transfer the next part of the filter cloth that has been cleaned to the drying area 10. A sensor for detecting ambient humidity is installed in the drying area 10 to detect the drying effect, so as to prevent the filter cloth from leaving the drying area 10 before being completely dried.

[0024] A top plate 12 is installed above the water tank 5, and a first through hole 13 for passing the filter cloth 4 is provided on the top plate 12, so as to reduce the connection area between the water tank 5 and the drying area 10 as much as possible, so as to avoid the water sprayed from the high-pressure nozzle 7 splashing into the drying area 10 during the flushing process, thereby affecting the drying effect. A top cover 14 is installed on the top plate 12, and the top cover 14 and the top plate 12 are combined to form the drying area 10, thereby reducing the contact area between the drying area 10 and the outside, avoiding a large amount of heat loss, and reducing the drying efficiency.

[0025] The top cover 14 is provided with a second through hole 15 for passing through the water outlet side.

[0026] The casing 1 is also equipped with a sensor for detecting the air quality of the air outlet end 3. When the sensor detects that the air quality of the air outlet end 3 drops to a preset value, the filter cloth 4 is cleaned as a whole, that is, the filter cloth 4 rotates one circle, and then rotates half a circle again, and the other side of the filter cloth 4 rotates to the position of the air outlet end 3 and fits against the side wall of the casing 1, that is, the filter cloth 4 is divided into side A and side B. The part currently fitting against the side wall of the casing 1 is side A, and after the next cleaning, the part fitting against the side wall of the casing 1 is side B. By alternating between the A and B sides, the service life of the filter cloth 4 is improved.

[0027] The type of filter cloth 4 can be changed according to customer needs

[0028] The lower end of the water tank 5 is provided with a sewage outlet.
