The filter module of the air conditioner is mainly used to purify the air entering the interior of the air conditioner, intercept dust, pollen, hair and other impurities in the air, and plays an important role in the normal operation of the air conditioner and the improvement of indoor air quality.

[0111] In some embodiments, the filter module comprises a first rotating roller 300 located at one end of the air conditioner air inlet. The filter module comprises a second rotating roller 400 located at the end of the air conditioner air inlet away from the first rotating roller 300. The filter module comprises a filter screen 500, which is annular and sleeved with the first rotating roller 300 and the second rotating roller 400. The first rotating roller 300 and the second rotating roller 400 rotate synchronously to realize the rotation of the filter screen 500.

[0112] In some embodiments, the filter module comprises a driving assembly for driving the first rotating roller 300 and the second rotating roller 400 to rotate.

[0113] In some embodiments, the driving assembly comprises a transmission shaft 900 which is rotatably connected in the housing 100. The transmission shaft 900 is arranged at one side of the filter screen 500. The driving assembly comprises a driving member for driving the transmission shaft 900 to rotate. The driving assembly comprises a first transmission gear 110 which is coaxially connected to one end of the first rotating roller 300. The driving assembly comprises a second transmission gear 120 which is coaxially connected to the transmission shaft 900 and engaged with the first transmission gear 110. The driving member drives the transmission shaft 900 to rotate, and the transmission shaft 900 drives the second transmission gear 120 to rotate. The second transmission gear 120 is engaged with the first transmission gear 110 to drive the first rotating roller 300 to rotate.

[0114] In some embodiments, the driving assembly comprises a third transmission gear 130 which is coaxially connected to one end of the second rotating roller 400. The driving assembly comprises a fourth transmission gear 140 which is coaxially connected to the transmission shaft 900 and engaged with the third transmission gear 130. The driving member drives the transmission shaft 900 to rotate, and the transmission shaft 900 drives the fourth transmission gear 140 to rotate. The fourth transmission gear 140 is engaged with the third transmission gear 130 to drive the second rotating roller 400 to rotate.

[0115] In some embodiments, the air conditioner indoor unit further comprises a cleaning module for cleaning the filter screen 500.

[0116] Through the above scheme, the first rotating roller 300 and the second rotating roller 400 of the module cooperate with the filter screen 500, which can realize the movement of the filter screen 500 and clean the dust on the filter screen 500 in cooperation with the cleaning module. Therefore, the filter screen 500 can effectively filter impurities in the air and improve the indoor air quality. The driving assembly utilizes the linkage of the transmission shaft 900, the driving member and the plurality of transmission gears. Only one driving member can drive the first rotating roller 300 and the second rotating roller 400 to work cooperatively, which reduces the number of driving members, reduces the cost, improves the synchronization rate of the filter screen 500 winding or unwinding, and avoids the filter screen 500 from being wrinkled or torn. The cleaning module is used for cleaning the filter screen 500, which can prolong the service life of the filter screen 500 and continuously ensure the filtering effect.

[0117] In some embodiments, the specific structures of the first transmission gear 110, the second transmission gear 120, the third transmission gear 130, the fourth transmission gear 140 and the structure of the cleaning module are the same as those described above, and will not be described here.
