The indoor air enters the shell and contacts the indoor heat exchanger, the indoor heat exchanger exchanges heat with the air, and then the air after heat exchange is output to the indoor under the action of the indoor fan, so as to realize the adjustment of the indoor temperature.

[0070] In the following, the present application will be described in detail through exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can be beneficially combined into other embodiments without further description.

[0071] Please refer to all the drawings, in one exemplary embodiment of the air conditioner indoor unit of the present application, the air conditioner indoor unit comprises a shell 100, the top of the shell 100 is provided with an air conditioner air inlet, the air conditioner air inlet is used for air passing and entering the shell 100.

[0072] In some embodiments, the air conditioner indoor unit comprises an indoor heat exchanger, which is arranged inside the shell 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In the cooling mode, the refrigerant evaporates in the heat exchanger and absorbs the heat of the surrounding air.

[0073] 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 input into the indoor after heat exchange through the indoor heat exchanger.

[0074] In some embodiments, the air conditioner indoor unit comprises a filter module, which is arranged in the shell 100. The filter module of the air conditioner is mainly used for purifying the air entering the inside of the air conditioner, intercepting 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.

[0075] In some embodiments, the filtering module comprises a first turning rod 200, a second turning rod 300, and a filter screen. The first turning rod 200 is arranged in the shell 100 and located at one end of the air conditioner air inlet. The second turning rod 300 is arranged in the shell 100 and located at the end of the air conditioner air inlet away from the first turning rod 200. The filter screen is annular and sleeved on the first turning rod 200 and the second turning rod 300. The first turning rod 200 and the second turning rod 300 located at both ends of the air conditioner air inlet jointly support the filter screen. The first turning rod 200 and the second turning rod 300 pull both ends of the filter screen, so that the annular filter screen can be stretched straight and kept in a relatively flat and stable filtering plane, preventing the filter screen from collapsing or wrinkling, and ensuring that air can pass through each part of the filter screen without obstruction, maintaining stable and efficient filtering effect.

[0076] In some embodiments, the air conditioner indoor unit comprises a cleaning module arranged in the shell 100. The cleaning module has multiple technical effects, which not only improves cleaning efficiency, prolongs the service life of the filter screen, and improves air quality, but also maintains air conditioner performance, enhances user experience, and promotes environmental protection and energy saving. These effects collectively bring users a more comfortable, healthy, and convenient air conditioner use experience.

[0077] In some embodiments, the cleaning module comprises a cleaning brush 400. The cleaning brush 400 is arranged in the shell 100 and abuts against the outer wall of the filter screen. The cleaning module comprises a driving brush 500 arranged in the shell 100, the peripheral wall of the driving brush 500 contacting the outer wall of the filter screen, and the length of the driving brush 500 being less than the width of the filter screen. The cleaning module comprises a driving motor 600 arranged at one end of the driving brush 500 close to the front side of the shell 100.

[0078] Through the above scheme, the filter screen is annular and sleeved on the first turning rod 200 and the second turning rod 300, and cooperates with the arrangement of the cleaning brush 400 and the driving brush 500 to provide a basic structure for subsequent filter screen cleaning mechanism without affecting the normal filtering function, ensuring the continuity and effectiveness of air filtration. By arranging the driving motor 600 at one end of the driving brush 500 close to the front side of the shell 100, the layout mode of the traditional driving motor 600 located at one end of the length direction of the shell 100 and at the end of the filter screen is changed, effectively saving the space in the length direction of the shell 100, avoiding excessive lengthening of the size of the air conditioner indoor unit due to the layout of the motor, and making the overall structure of the air conditioner indoor unit more compact, which can adapt to more space-limited installation environments.

[0079] In some embodiments, the end of the driving brush 500 away from the driving motor 600 is point A, the end of the driving motor 600 away from the driving brush 500 is point B, and the distance from point A to point B is not more than the width of the filter screen. Through this design, the compactness of the combination of the driving motor 600 and the driving brush 500 in space is further ensured, preventing the two from being too long to exceed the range of the filter screen, thereby affecting the layout of other components inside the air conditioner indoor unit or causing the overall size to increase, which helps to maintain the design goal of miniaturization of the air conditioner indoor unit.

[0080] In some embodiments, the side of the driving brush 500 facing the front of the shell 100 is the C end, and point A is located on the C end surface. The C end surface is flush with the side of the filter screen facing the front of the shell 100.

[0081] In some embodiments, the side of the driving motor 600 away from the front of the shell 100 is not more than the side of the filter screen facing the back of the shell 100. This ensures that the driving motor 600 plus the driving brush 500 can not exceed the width of the filter screen. In this way, while ensuring that the driving motor 600 does not occupy the length direction space of the shell 100, the driving motor 600 also does not occupy the front-back direction space of the shell 100.

[0082] In some embodiments, the driving brush 500 and the driving motor 600 are located on the side of the filter screen facing the bottom of the shell 100; the filter screen is projected from the top of the shell 100 to the bottom of the shell 100, and the driving brush 500 and the driving motor 600 are located within the projected area of the filter screen. This layout makes full use of the space below the filter screen, avoids occupying additional space in other directions of the shell 100, optimizes the space utilization inside the air conditioner indoor unit, and also makes the positions of the driving brush 500 and the driving motor 600 relatively concentrated, which is convenient for the design and arrangement of the transmission structure and improves the working stability and reliability of the cleaning module.

[0083] In some embodiments, the cleaning module further comprises a first gear 700 and a second gear 800. The first gear 700 is arranged at the end of the driving brush 500 away from the driving motor 600. The second gear 800 is engaged with the first gear 700, and the second gear 800 is fixedly connected to one end of the cleaning brush 400. The first gear 700 and the second gear 800 arranged in the cleaning module are engaged with each other, realizing the mechanical transmission connection between the driving brush 500 and the cleaning brush 400. When the driving motor 600 drives the driving brush 500 to rotate, the cleaning brush 400 can work synchronously through gear transmission. The rotating direction of the cleaning brush 400 is similar to the rotating direction of the filter screen, improving the friction frequency of the cleaning brush 400 on the filter screen per unit time, effectively cleaning the filter screen comprehensively, improving the efficiency and uniformity of the filter screen cleaning, ensuring that the filter screen always maintains good filtering performance during long-term use, and reducing the problem of air conditioner performance degradation caused by filter screen blockage. Moreover, one driving motor 600 can realize the rotation of the cleaning brush 400 and the driving brush 500, saving cost.

[0084] In some embodiments, the cleaning brush 400 is located below the first turning rod 200, and the cleaning brush 400 and the first turning rod 200 clamp the filter screen. During cleaning, on the one hand, the cleaning brush 400 can effectively scrape and clean the filter screen, and on the other hand, the clamping action of the first turning rod 200 can prevent the filter screen from shaking or shifting during cleaning, ensuring that the filter screen receives cleaning in a stable state, improving the accuracy and reliability of cleaning, and also helping to prolong the service life of the filter screen. Moreover, the force of the abutment of the cleaning brush 400 on the filter screen is improved, the pressure and pressure intensity are improved, and the cleaning effect on the filter screen is improved.

[0085] In some embodiments, a tooth comb 900 is arranged below the cleaning brush 400, and the tooth comb 900 is used to contact the cleaning brush 400. When the cleaning brush 400 works, the tooth comb 900 can comb the dust and impurities adsorbed on the cleaning brush 400, prevent the cleaning brush 400 from being affected by the accumulation of impurities, ensure that the cleaning brush 400 is always in a good working state, continuously and effectively clean the filter screen, and further improve the stability and long-term effectiveness of the entire cleaning module for cleaning the filter screen.

[0086] In some embodiments, a dust collecting box 110 is arranged below the cleaning brush 400. Through the arrangement of the dust collecting box 110, it is convenient to collect the dust and impurities brushed off by the cleaning brush 400 during cleaning of the filter screen, avoid the dust from scattering everywhere in the air conditioner indoor unit, pollute other parts or re-enter the air circulation, maintain the clean environment inside the air conditioner indoor unit, and also facilitate regular cleaning of dust, reducing the difficulty and cost of air conditioner maintenance.

[0087] In some embodiments, the filter screen comprises a support frame 101, the first steering rod 200 and the second steering rod 300 are both rotationally connected to the support frame 101. The driving brush 500 and the driving motor 600 are located on the support frame 101. The first steering rod 200 and the second steering rod 300 are both rotationally connected to the support frame 101, which provides a stable structural basis for the installation and rotation of the filter screen, so that the filter screen can rotate flexibly during operation, and ensures that the airflow can pass through each part of the filter screen uniformly, thereby improving the filtering effect. At the same time, the driving brush 500 and the driving motor 600 are located on the support frame 101, so that the combination of the entire cleaning module and the filter screen is more compact, and the structural integrity is stronger, which is conducive to improving the stability and reliability of the air conditioner indoor unit during operation, and reducing faults caused by loose or displacement of parts.

[0088] In some embodiments, the sidewall of the support frame 101 is provided with a containing cavity, and the driving motor 600 is arranged in the containing cavity. The output shaft of the driving motor 600 penetrates the containing cavity and is coaxially connected with the driving brush 500. The design of the containing cavity further optimizes the space utilization, hides the driving motor 600 in the support frame 101, avoids exposing the driving motor 600 in the internal space of the air conditioner indoor unit, reduces the additional space occupied by the external structure of the motor, and also plays a certain protective role for the motor, prevents the motor from being collided or interfered by other parts, improves the service life and working safety of the motor, and also helps to improve the overall aesthetics and internal structure neatness of the air conditioner indoor unit.

[0089] In some embodiments, the cleaning brush 400 is also rotationally connected to the support frame 101. The arrangement of the cleaning brush 400 is facilitated.

[0090] In some embodiments, the first steering rod 200 and the second steering rod 300 are parallel. The parallel arrangement of the first steering rod 200 and the second steering rod 300 can significantly improve the stability and filtering effect of the filter module. The parallel structure makes the filter screen bear force uniformly, reduces the risk of local pulling and deformation, ensures that the filter screen can still maintain a flat and stable filtering plane under long-time operation and airflow impact, and ensures that the air passes uniformly and effectively intercepts impurities.

[0091] In some embodiments, the driving brush 500 is parallel to the first steering rod 200, which ensures that the driving brush 500 drives the filter screen to rotate smoothly under the first steering rod 200 and the second steering rod 300.
