At present, with the implementation of the double carbon policy and the increasing demand for healthy life quality, the cleaning problem of air conditioner filter screens has gradually been put on the agenda. If the air conditioner filter screen is not cleaned regularly, a large amount of dust and bacteria will accumulate, which not only affects the working efficiency of the air conditioner and increases energy consumption, but also may affect human health, such as causing respiratory diseases. Therefore, a cleaning module is usually provided in the prior art to clean the filter screen.

[0004] However, the cleaning module in the prior art is usually integrated. Therefore, when the cleaning module and the filter screen need to be cleaned and maintained, the air conditioner needs to be disassembled, the cleaning module and the filter screen are disassembled as a whole, and then reassembled after cleaning and maintenance.

In the cooling mode, the refrigerant evaporates in the heat exchanger and absorbs the heat of the surrounding air.

[0089] In some embodiments, the air conditioner indoor unit comprises an indoor fan, which is arranged inside the shell 100; the indoor fan makes the airflow input into the shell 100 through the air conditioner air inlet and then input into the indoor after heat exchange through the indoor heat exchanger.

[0090] In some embodiments, the air conditioner indoor unit comprises a disassembly structure, which can be directly taken out from the air conditioner air inlet.

[0091] In some embodiments, the detachable structure comprises a support frame 200 which is detachably arranged at the air inlet of the air conditioner. The primary function of the support frame 200 is to fix the filter screen 700 so that it can be accurately positioned at the air inlet of the air conditioner or other places where filtration is required. Without the support frame 200, the filter screen 700 may be displaced.

[0092] In some embodiments, the detachable structure comprises a first winding roller 300 which is rotatably connected to one end of the support frame 200.

[0093] In some embodiments, the detachable structure comprises a second winding roller 400 which is rotatably connected to one end of the support frame 200 close to the first winding roller 300.

[0094] In some embodiments, the detachable structure comprises a first gear 500 which is arranged at one end of the first winding roller 300.

[0095] In some embodiments, the detachable structure comprises a second gear 600 which is arranged at one end of the second winding roller 400, and the first gear 500 and the second gear 600 are engaged. When the first gear 500 rotates, it will drive the second gear 600 to rotate, so as to realize the linkage of the first winding roller 300 and the second winding roller 400.

[0096] In some embodiments, the detachable structure comprises a filter screen 700, both ends of which are wound on the first winding roller 300 and the second winding roller 400 respectively. The filter screen 700 is used to filter impurities in the air passing through the air inlet of the air conditioner, so as to avoid the impurities affecting the internal components of the air conditioner.

[0097] In some embodiments, the detachable structure comprises a cleaning brush 800 which is arranged in the support frame 200 and can contact the filter screen 700. The main function of the cleaning brush 800 contacting the filter screen 700 is to effectively remove dust on the filter screen 700. When the brush moves on the filter screen 700, the bristles of the brush can penetrate into the pores of the filter screen 700, so as to clean the filter screen 700.

[0098] In some embodiments, the air conditioner indoor unit further comprises a fixing structure which is usually fixed in the air conditioner.

[0099] In some embodiments, the fixing structure comprises a mounting box 120 which is arranged in the shell 100.

[0100] In some embodiments, the fixed structure comprises a first driving motor 130, which is arranged in the mounting box 120.

[0101] In some embodiments, the fixed structure comprises a first driving gear 140, which is connected to the first driving motor 130.

The filter screen 700 is arranged around the first turning rod 230. That is, one end of the filter screen 700 is wound on the first winding roller 300, and the filter screen 700 is wound on the second winding roller 400 after passing through the first turning rod 230. The first turning rod 230 ensures that the filter screen 700 can close the air inlet, so that the airflow passing through the air inlet can be filtered by the filter screen 700.

[0105] In some embodiments, the winding amount of the first winding roller 300 and the winding amount of the second winding roller 400 are the same, ensuring that the filter screen 700 can be stretched straight, avoiding a large gap between the edge of the filter screen 700 and the shell 100, and ensuring the filtering effect of the filter screen 700.

[0106] In some embodiments, the diameter of the first winding roller 300 is A, and the diameter of the second winding roller 400 is B. The diameter of the first gear 500 is C, and the diameter of the second gear 600 is D. It is ensured that A:B=D:C. In this way, the winding amount of the first winding roller 300 and the second winding roller 400 is the same.

[0107] In some embodiments, the dismounting structure further comprises a first transmission gear 110, the first transmission gear 110 is engaged with the first gear 500, and the first drive gear 140 is engaged with the first transmission gear 110 after the dismounting structure is installed in the shell 100. The first transmission gear 110 can make the first winding roller 300 not need to be particularly close to the edge of the support frame 200, avoiding interference caused by the contact between the filter screen 700 on the first winding roller 300 and the support frame 200. Moreover, the first transmission gear 110 can adjust the transmission ratio as needed, change the winding and unwinding speed of the filter screen 700, and flexibly cope with different air quality environments. For example, in the pollen season and other high-particle-pollution periods, the replacement rhythm of the filter screen 700 is accelerated; in the daily mild pollution, the speed is moderately reduced to save energy and reduce noise. At the same time, the transmission stability is optimized, the single-stage gear wear is reduced, the system reliability is improved, the clean system of the filter screen 700 is ensured to operate persistently and accurately, the complex working conditions are adapted, the equipment downtime is reduced, and the user experience is improved.

[0108] In some embodiments, the first winding roller 300 and the second winding roller 400 are parallel. The length direction of the first winding roller 300 and the second winding roller 400 is perpendicular to the length direction of the shell 100.

[0109] In some embodiments, the second gear 600 is located on the side of the first gear 500 away from the first drive gear 140. The first transmission gear 110 is located on the side of the first gear 500 away from the second gear 600. The first transmission gear 110 is rotationally connected to the support frame 200, and the axes of the first transmission gear 110, the first gear 500, and the second gear 600 are parallel. When the dismounting structure is installed in the shell 100, the axis of the first drive gear 140 is also parallel to the axis of the first transmission gear 110.

[0110] In some embodiments, the dismounting structure further comprises a tooth comb 900 for cleaning the cleaning brush 800. The cleaning brush 800 is in contact with the tooth comb 900, and the tooth comb 900 sweeps the bristles of the cleaning brush 800.

[0111] Please refer to all the drawings, in some embodiments, the fixed structure further comprises a second driving motor 150, which is arranged in the mounting box 120. The second driving motor 150 is used to drive the cleaning brush 800 to rotate. The second driving motor 150 can drive the cleaning brush 800 to rotate and contact the tooth comb 900, so as to realize the cleaning of the cleaning brush 800, effectively solve the self-cleaning problem of the cleaning brush 800, prevent dust from being hardened and blocked on the cleaning brush 800, always maintain the cleaning efficiency of the cleaning brush 800, and ensure that the filter screen 700 can be deeply cleaned every time.

[0112] In some embodiments, the air conditioner indoor unit further comprises a second turning rod 240, which is located on the side of the first winding roller 300 away from the second winding roller 400. The filter screen 700 is wound on the first winding roller 300 after passing through the second turning rod 240.
