Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning equipment, and in particular to an air-conditioning indoor unit. Background Art

[0002] An air conditioner, or air conditioner, is a device that manually adjusts and controls the temperature, humidity, flow rate, and other parameters of the ambient air within a building or structure. To meet real-life needs, some air conditioners have a fresh air function, which can transfer outdoor air indoors.

[0003] Air conditioner filter cleaning is becoming increasingly important. If not regularly cleaned, these filters can accumulate dust and bacteria, which not only affects air conditioner efficiency and increases energy consumption, but can also negatively impact human health, such as respiratory illnesses. Wall-mounted air conditioners, in particular, are difficult to clean because they hang from indoor walls. Therefore, existing technologies often incorporate cleaning modules within these systems.

[0004] The current industry solution is to place the air conditioner cleaning device inside the panel. These filter cleaning devices are often relatively large, taking up space and impacting the overall appearance of the machine, especially in terms of thickness. Previous self-cleaning machines were very thick, resulting in an unsightly appearance. Furthermore, the cleaning device is complex, unreliable, and expensive, resulting in poor cleaning performance. Furthermore, because the filter must be connected to the cleaning module, the installation of the filter is affected, reducing installation efficiency. Utility Model Content

[0005] The utility model solves one of the technical problems in the related art at least to a certain extent.

[0006] To this end, the present application provides an air conditioner indoor unit in which a filter is placed over a first rotating rod and a second rotating rod, separating the filter into two layers. Air is filtered through the upper filter before being filtered through the lower filter. Consequently, the upper filter contains more impurities and dust. Because the drive brush abuts the filter, when the drive assembly rotates the drive brush, it also causes the filter to roll, gradually rolling the dust-laden upper filter to the lower layer. At this point, the cleaning brush removes the dust from the filter, effectively cleaning the filter. The annular filter filters through both layers, providing excellent filtration efficiency and reliable movement. Cleaning is possible in any position. Furthermore, since the filter position does not require detection, a position sensor is not required, saving costs. Furthermore, during installation, the main frame and side brackets are connected via elastic snaps. Simply placing the filter over the main frame and side brackets and then connecting the main frame and side brackets allows for easy support of the filter, making operation convenient.

[0007] In order to achieve the above object, the utility model provides an air conditioner indoor unit, comprising:

[0008] The shell has an air-conditioning air inlet on the top;

[0009] an indoor heat exchanger, which is disposed inside the shell;

[0010] an indoor fan disposed inside the housing; under the action of the indoor fan, air flow is input into the housing through the air-conditioning air inlet, and is input into the room after heat exchange through the indoor heat exchanger;

[0011] a first rotating rod, the first rotating rod being disposed in the housing and located at one end of the air inlet in the length direction of the air conditioner;

[0012] a second rotating rod, the second rotating rod being disposed in the housing and located at an end of the air inlet of the air conditioner in the length direction away from the first rotating rod;

[0013] A filter screen, the filter screen is annular and is sleeved on the first rotating rod and the second rotating rod;

[0014] A cleaning module is disposed in the housing; the cleaning module comprises:

[0015] a cleaning brush, the cleaning brush being used to abut against the filter screen;

[0016] a driving brush, the driving brush being used to abut against the filter screen;

[0017] A driving assembly, the driving assembly is used to drive the driving brush to rotate;

[0018] When the driving brush rotates, the filter screen is driven to roll, and at this time, the cleaning brush cleans the filter screen.

[0019] In the technical solution, the filter is installed behind the first and second rotating rods. The filter is divided into two layers, the upper and lower layers. The air is filtered by the upper filter first and then by the lower filter. Therefore, there is more impurities and dust on the upper filter.

[0020] Because the driving brush is in contact with the filter, when the driving assembly drives the driving brush to rotate, it also drives the filter to roll. The filter with more dust on the upper layer gradually rolls to the lower layer. At this time, the dust on the filter is cleaned by the cleaning brush to achieve cleaning of the filter.

[0021] The ring-shaped filter screen filters through two layers, providing excellent filtration efficiency and reliable operation. It can be cleaned in any condition. Furthermore, there is no need to detect the filter screen position, eliminating the need for a position sensor, saving costs.

[0022] In some embodiments of the present application, a support frame is installed at the air inlet of the air conditioner, and the first rotating rod and the second rotating rod are respectively arranged at both ends of the support frame; the filter is arranged on the first rotating rod and the second rotating rod and is also arranged on the support frame.

[0023] In the technical solution, the support frame is set up to enhance the support stability of the filter, ensure the stability of the filter during the rolling cleaning process, and at the same time simplify the installation structure to facilitate maintenance and replacement of the filter.

[0024] In some embodiments of the present application, the support frame includes:

[0025] a main frame, wherein the first rotating rod is provided at one end of the main frame;

[0026] a side bracket, wherein the side bracket is arranged at an end of the main frame away from the first rotating rod, and the second rotating rod is arranged at an end of the side bracket away from the main frame;

[0027] The side bracket is connected to the main frame via an elastic buckle.

[0028] In the technical solution, during installation, the filter can be placed on the main frame and side brackets first, and then the main frame and side brackets are connected to each other. The filter can be supported by adjusting the angle, which facilitates production and manufacturing. In addition, the support frame adopts a design that connects the main frame and side brackets with elastic clips. This not only facilitates assembly and disassembly, but also improves the flexibility and adaptability of the structure, making it easy to adjust according to the needs of different air conditioner models.

[0029] In some embodiments of the present application, the support frame further includes:

[0030] an upper grille, the upper grille being arranged on a side of the main frame and the side bracket away from the indoor fan;

[0031] A lower bracket is arranged on a side of the main bracket and the side bracket close to the indoor fan.

[0032] In the technical solution, an upper grille and a lower bracket are added to the support frame to further stabilize the position of the filter and prevent it from shifting or falling off during rolling. At the same time, it optimizes the airflow path and improves the heat exchange efficiency of the air conditioner.

[0033] In some embodiments of the present application, the driving component includes:

[0034] a first gear, the first gear being coaxially connected to one end of the cleaning brush;

[0035] a second gear, the second gear being coaxially connected to one end of the driving brush, the first gear being meshed with the second gear;

[0036] A driving motor is used to drive the first gear or the second gear to rotate.

[0037] In this technical solution, a first gear meshes with a second gear, and a drive motor drives one of the gears to rotate, thereby driving the cleaning brush and the driving brush to rotate synchronously in opposite directions. Therefore, the filter screen's contact with the cleaning brush moves in the opposite direction of the bristles' movement, increasing friction between the cleaning brush and the filter screen, thereby enhancing cleaning force and, consequently, effectiveness. Furthermore, the drive assembly requires only a single motor to simultaneously drive the filter screen and the cleaning brush, resulting in a compact structure that saves space and costs.

[0038] In some embodiments of the present application, the driving assembly further includes a transmission gear, wherein the transmission gear is engaged with the first gear or the second gear;

[0039] The driving motor is used to drive the transmission gear to rotate.

[0040] In the technical solution, a transmission gear is added to the drive assembly, allowing the drive motor to indirectly drive the cleaning brush and driving brush through the transmission gear. The transmission ratio can be adjusted as needed to optimize the cleaning effect. In addition, this design can avoid directly placing the drive motor at the end of the driving brush or cleaning brush. The drive motor can be placed to the side of the driving brush or cleaning brush, thereby reducing the space occupied by the front and rear of the air conditioner and shortening the size of the air conditioner indoor unit.

[0041] In some embodiments of the present application, the cleaning module further includes a fixing frame disposed in the housing; the cleaning brush, the driving brush and the driving assembly are all disposed on the fixing frame.

[0042] In the technical solution, a fixing frame is provided for installing the cleaning brush, driving brush and driving assembly, which improves the integration and stability of the entire cleaning module, facilitates maintenance and replacement of components, and reduces interference with other internal structures of the air conditioner indoor unit.

[0043] In some embodiments of the present application, a dust box is detachably connected to the bottom of the fixing frame.

[0044] In the technical solution, a detachable dust box is set at the bottom of the fixed frame to facilitate the collection of dust and impurities generated during the cleaning process, reduce secondary pollution after cleaning, and improve the hygiene performance and user experience of the air conditioner.

[0045] In some embodiments of the present application, a tooth comb is provided in the fixing frame, and the tooth comb is used to contact the cleaning brush.

[0046] In the technical solution, a tooth comb is arranged in the fixed frame to contact the cleaning brush, which helps to remove dust and impurities attached to the cleaning brush when it rotates, maintains the cleanliness and working efficiency of the cleaning brush, and extends the service life of the cleaning module.

[0047] In addition, the present application also provides an air conditioner indoor unit, which includes:

[0048] The shell has an air-conditioning air inlet on the top;

[0049] an indoor heat exchanger, which is disposed inside the shell;

[0050] an indoor fan disposed inside the housing; under the action of the indoor fan, air flow is input into the housing through the air-conditioning air inlet, and is input into the room after heat exchange through the indoor heat exchanger;

[0051] a first rotating rod, the first rotating rod being disposed in the housing and located at one end of the air inlet in the length direction of the air conditioner;

[0052] a second rotating rod, the second rotating rod being disposed in the housing and located at an end of the air inlet of the air conditioner in the length direction away from the first rotating rod;

[0053] A filter screen, the filter screen is annular and is sleeved on the first rotating rod and the second rotating rod;

[0054] A cleaning module is disposed in the housing; the cleaning module comprises:

[0055] a cleaning brush, the cleaning brush being used to abut against the filter screen;

[0056] a driving structure, wherein the driving structure is used to drive the filter to roll on the first grab bar and the second rotating bar, and the driving structure drives the cleaning brush to rotate, and the cleaning brush and the filter roll in opposite directions;

[0057] The driving structure drives the filter screen to roll, and the cleaning brush cleans the filter screen.

[0058] In the technical solution, the filter is installed behind the first and second rotating rods. The filter is divided into two layers, the upper and lower layers. The air is filtered by the upper filter first and then by the lower filter. Therefore, there is more impurities and dust on the upper filter.

[0059] The driving component drives the filter to roll, and the filter with more dust on the upper layer gradually rolls to the lower layer. At this time, the dust on the filter is cleaned by the cleaning brush to achieve the cleaning of the filter.

[0060] The ring-shaped filter screen filters through two layers, providing excellent filtration efficiency and reliable operation. It can be cleaned in any condition. Furthermore, there is no need to detect the filter screen position, eliminating the need for a position sensor, saving costs.

[0086] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may also be beneficially combined in other embodiments.

[0087] In this application, the air conditioner includes an outdoor unit and an indoor unit. The outdoor unit is equipped with a compressor, an outdoor heat exchanger, and an outdoor fan. The indoor unit is equipped with an indoor heat exchanger and an indoor fan. The outdoor heat exchanger and the indoor heat exchanger serve as the evaporator and condenser, respectively, to achieve heat exchange. The indoor fan outputs the air after heat exchange in the indoor heat exchanger to the indoor room, achieving indoor cooling or heating.

[0088] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0089] As attached Figures 1 to 5 As shown, in an exemplary embodiment of an air conditioning indoor unit according to the present invention, the air conditioning indoor unit comprises a housing 100 having an air conditioning inlet defined at the top thereof. The air conditioning indoor unit may further comprise an indoor heat exchanger 200 disposed within the housing 100. The air conditioning indoor unit may further comprise an indoor fan 300 disposed within the housing 100. Under the action of the indoor fan 300, air is input into the housing 100 through the air conditioning inlet, and then, after heat exchange in the indoor heat exchanger 200, is input into the indoor room.

[0090] Please refer to Figure 5 、 Figure 13 and Figure 14 The air conditioner indoor unit also includes a filter assembly, which includes a first rotating rod 400, a second rotating rod 500, and a filter 600. The first rotating rod 400 is disposed in the housing 100 and is located at one end of the air conditioner air inlet in the length direction. The air conditioner indoor unit may also include a second rotating rod 500, which is disposed in the housing 100 and is located at one end of the air conditioner air inlet in the length direction away from the first rotating rod 400. The air conditioner indoor unit may also include a filter 600, which is annular and is mounted on the first rotating rod 400 and the second rotating rod 500. The filter 600 is supported by the first rotating rod 400 and the second rotating rod 500. After being supported by the first rotating rod 400 and the second rotating rod 500, the filter 600 is divided into two layers, upper and lower. The air entering the housing 100 is filtered by the upper filter 600 and then by the lower filter 600. The filter screen 600 can roll on the first rotating rod 400 and the second rotating rod 500 .

[0091] Please refer to Figures 6 to 17 The air conditioner indoor unit may further include a cleaning module disposed within the housing 100. The cleaning module includes a cleaning brush 800, a driving brush 900, and a driving assembly. The cleaning brush 800 is configured to abut the filter 600. The driving brush 900 is configured to abut the filter 600. The driving assembly is configured to rotate the driving brush 900. Rotating the driving brush 900 causes the filter 600 to roll, thereby cleaning the filter 600.

[0092] With the above solution, after the filter 600 is mounted on the first rotating rod 400 and the second rotating rod 500, the filter 600 is divided into two layers, and the air is first filtered by the upper filter 600 and then filtered by the lower filter 600. Therefore, there is more impurities and dust on the upper filter 600.

[0093] Because the driving brush 900 is in contact with the filter 600, when the driving component drives the driving brush 900 to rotate, it also drives the filter 600 to roll. The filter 600 with more dust on the upper layer gradually rolls to the lower layer. At this time, the dust on the filter 600 is cleaned by the cleaning brush 800 to achieve cleaning of the filter 600.

[0094] The ring-shaped filter 600 filters through two layers, providing excellent filtration and reliable operation. It can be cleaned in any state. Furthermore, there is no need to detect the position of the filter 600, eliminating the need for a position sensor, thus saving costs.

[0095] Please refer to Figures 5 to 15 In some embodiments, the cleaning module is located within the housing 100 at one end of the indoor heat exchanger 200 in the longitudinal direction. Alternatively, the cleaning module is located within the housing 100 at one end of the indoor fan 300 in the longitudinal direction. This reduces the space occupied by the air conditioner in the front-to-back direction and in the height direction, ensuring a well-proportioned and aesthetically pleasing air conditioner and improving the user experience.

[0096] Please refer to Figures 1 to 12 In some embodiments, the entire filter 600 is located inside the housing 100, with the upper layer of the filter 600 near the air conditioner inlet and the lower layer of the filter 600 near the indoor heat exchanger 200. Air entering through the air conditioner inlet is filtered by the upper filter 600 and then filtered by the lower filter 600 before entering the housing 100 to exchange heat with the indoor heat exchanger 200. The two layers of filter 600 provide better filtering and enhance the air purification effect.

[0097] Please refer to Figure 5 、 Figure 13 and Figure 14 In some embodiments, the first rotating rod 400 and the second rotating rod 500 are parallel to each other, ensuring the flatness of the filter 600 after being supported. The filter 600 is arranged in an annular belt shape. When the first rotating rod 400 and the second rotating rod 500 support the filter 600, the filter 600 can cover the air inlet of the air conditioner, preventing dust from entering the housing 100 through the gap between the filter 600 and the air inlet of the air conditioner, thereby ensuring the filtering effect.

[0098] In some embodiments, the first rotating rod 400 and the second rotating rod 500 are both rotatably connected to the housing 100. When the filter screen 600 is driven to roll, the filter screen 600 also drives the first rotating rod 400 and the second rotating rod 500 to rotate, converting static friction into rolling friction. This reduces the resistance of the filter screen 600 during rolling, improves the rolling stability of the filter screen 600, reduces wear on the filter screen 600, and increases the service life of the filter screen 600.

[0099] In some embodiments, the drive brush 900 is parallel to the first rotating rod 400 and the second rotating rod 500. As the drive brush 900 rotates, it causes the filter 600 to roll through friction. The drive brush 900 directly and effectively drives the filter 600 through friction during rotation. This direct transmission reduces energy loss in the intermediate transmission link, improves energy transfer efficiency, and enables the filter 600 to roll at a higher speed and with a more stable trajectory.

[0100] Please refer to Figures 5 to 16 In some embodiments, the filter assembly includes a support frame, which is positioned at the air inlet of the air conditioner. A first rotating rod 400 and a second rotating rod 500 are respectively positioned at opposite ends of the support frame. The filter 600 is positioned within the first rotating rod 400 and the second rotating rod 500, and is also positioned within the support frame. The support frame enhances the support stability of the filter 600, ensuring smooth operation during rolling cleaning. It also simplifies the installation structure, facilitating maintenance and replacement of the filter 600.

[0101] In some embodiments, the support frame is detachably connected to the housing 100 and is near the air inlet of the air conditioner. It is easy to install manually, and the structural parts are inside the housing 100 and are not exposed to the user's field of vision.

[0102] Please refer to Figures 6 to 15 In some embodiments, the support frame includes a main frame 701, with the first rotating rod 400 disposed at one end of the main frame 701. The support frame includes a side bracket 702, which is disposed at an end of the main frame 701 away from the first rotating rod 400. The second rotating rod 500 is disposed on an end of the side bracket 702 away from the main frame 701. The side bracket 702 is connected to the main frame 701 via an elastic buckle.

[0103] During installation, the filter 600 can be placed on the main frame 701 and side brackets 702, and then the main frame 701 and side brackets 702 are connected to each other. By adjusting the angle, the filter 600 is supported, which facilitates production. In addition, the support frame adopts a design that connects the main frame 701 and side brackets 702 with elastic clips, which not only facilitates assembly and disassembly, but also improves the flexibility and adaptability of the structure, making it easy to adjust according to the needs of different air conditioner models.

[0104] Please refer to Figure 18 and Figure 19 In some embodiments, an elastic clip is provided on the main frame 701 and includes an elastic sheet 180 with a latch 190 disposed thereon. A latch slot 210 is provided on the side frame 702. When the elastic sheet 180 is pushed, the latch 190 moves toward the latch slot 210. When the elastic sheet 180 is released, the latch 190 snaps into the latch slot 210 upon rebounding, thereby connecting the main frame 701 to the side frame 702.

[0105] The elastic sheet 180 may be directly connected to the main frame 701. Alternatively, a deformation cavity for bending the elastic sheet 180 may be provided between the elastic sheet 180 and the main frame 701.

[0106] In some embodiments, a resilient clip is provided on the side bracket 702 and includes an elastic sheet 180 with a latch 190 disposed thereon. A latch slot 210 is provided on the main frame 701. When the elastic sheet 180 is pushed, the latch 190 moves toward the latch slot 210. When the elastic sheet 180 is released, the latch 190 snaps into the latch slot 210 upon rebounding, connecting the main frame 701 to the side bracket 702.

[0107] The elastic sheet 180 and the side bracket 702 may be directly connected. Alternatively, a deformation cavity for bending the elastic sheet 180 may be provided between the elastic sheet 180 and the side bracket 702 .

[0108] In some embodiments, a chamfer is provided on one side of the clamping block 190 facing the clamping slot 210 , so that the elastic sheet 180 can be deformed after the clamping block 190 contacts the corresponding structure during installation.

[0109] In some embodiments, the main frame 701 and the side frame 702 can rotate at their elastic snap-fit ​​connection. This means they can be arranged at an angle. During installation, after connecting the main frame 701 and the side frame 702, the two frames can be bent at an angle. After wrapping the filter 600 around the main frame 701 and the side frame 702, the two frames can be bent so that they form a flat surface. This straightens the filter 600, facilitating manual installation.

[0110] Please refer to Figures 6 to 10 In some embodiments, the support frame further includes an upper grille 700, which is disposed on the side of the main frame 701 and side bracket 702 away from the indoor fan 300. The support frame further includes a lower bracket 703, which is disposed on the side of the main frame 701 and side bracket 702 closer to the indoor fan 300. The addition of the upper grille 700 and lower bracket 703 to the support frame further stabilizes the position of the filter 600, preventing it from shifting or falling off during rolling, while also optimizing the airflow path and improving the heat exchange efficiency of the air conditioner.

[0111] In some embodiments, the upper grille 700 is disposed at the air inlet of the air conditioner. The upper grille 700 is connected to the main frame 701 and the side bracket 702 to secure the main frame 701 and the side bracket 702, thereby preventing bending between the main frame 701 and the side bracket 702 and ensuring that the filter 600 can be supported by the main frame 701 and the side bracket 702.

[0112] In some embodiments, the lower bracket 703 is connected to the main frame 701, and the lower bracket 703 is also connected to the side bracket 702. This prevents bending between the main frame 701 and the side bracket 702, ensuring that the filter 600 can be supported by the main frame 701 and the side bracket 702.

[0113] In some embodiments, the drive assembly includes a first gear 130, which is coaxially connected to one end of the cleaning brush 800. The drive assembly may also include a second gear 140, which is coaxially connected to one end of the driving brush 900, and the first gear 130 meshes with the second gear 140. The drive assembly may also include a drive motor 160, which is used to drive the first gear 130 or the second gear 140 to rotate.

[0114] By meshing the first gear 130 and the second gear 140, the drive motor 160 drives one of the gears to rotate, thereby driving the cleaning brush 800 and the driving brush 900 to rotate synchronously in opposite directions. Therefore, the direction of travel of the side of the filter 600 where it contacts the cleaning brush 800 is opposite to the direction of travel of the bristles of the cleaning brush 800. This increases the friction between the cleaning brush 800 and the filter 600, thereby enhancing the cleaning force and, consequently, the cleaning effect. Furthermore, the structure of the drive assembly requires only one motor 160 to simultaneously drive the movement of the filter 600 and the cleaning brush 800, resulting in a compact structure, space saving, and cost savings.

[0115] In some embodiments, the cleaning brush 800 is located below the first rotating rod 400. The cleaning brush 800 and the first rotating rod 400 clamp the cleaning filter 600 to improve the cleaning effect.

[0116] In some embodiments, the drive assembly further includes a transmission gear 150, which meshes with the first gear 130 or the second gear 140; a drive motor 160 is used to drive the transmission gear 150 to rotate. Adding the transmission gear 150 to the drive assembly allows the drive motor 160 to indirectly drive the cleaning brush 800 and the driving brush 900 to rotate via the transmission gear 150. The transmission ratio can be adjusted as needed to optimize the cleaning effect. This design also avoids the drive motor 160 being directly positioned at the end of the driving brush 900 or the cleaning brush 800. Instead, the drive motor 160 can be positioned to one side of the driving brush 900 or the cleaning brush 800, thereby reducing the space occupied by the front and rear of the air conditioner and shortening the size of the air conditioner indoor unit.

[0117] In some embodiments, the transmission gear 150, the first gear 130, and the second gear 140 may have the same module, but may have different numbers of teeth and pitch circle diameters. The transmission ratio of the transmission gear 150, the first gear 130, and the second gear 140 may be adjusted as needed to adjust the movement speed of the filter 600 and the rotation speed of the cleaning brush 800.

[0118] In some embodiments, the cleaning module further includes a mounting bracket 110 disposed within the housing 100. The cleaning brush 800, the driving brush 900, and the driving assembly are all mounted on the mounting bracket 110. The mounting bracket 110, for mounting the cleaning brush 800, the driving brush 900, and the driving assembly, improves the integration and stability of the entire cleaning module, facilitates maintenance and component replacement, and reduces interference with other internal structures of the air conditioner indoor unit.

[0119] In some embodiments, a dust box 170 is detachably connected to the bottom of the fixing frame 110. The detachable dust box 170 is provided at the bottom of the fixing frame 110 to facilitate the collection of dust and impurities generated during the cleaning process, thereby reducing secondary pollution after cleaning and improving the hygienic performance and user experience of the air conditioner indoor unit.

[0120] In some embodiments, the dust box 170 is connected to the fixing frame 110 , and the connection methods include but are not limited to elastic buckles, snap connections, threaded connector connections, plug-in connections, etc.

[0121] In some embodiments, the dust box 170 is connected to the housing 100, and the connection methods include but are not limited to elastic buckles, snap connections, threaded connector connections, plug-in connections, etc.

[0122] In some embodiments, a tooth comb 120 is disposed within the fixing frame 110, and the tooth comb 120 is configured to contact the cleaning brush 800. Providing the tooth comb 120 within the fixing frame 110 so as to contact the cleaning brush 800 helps remove dust and impurities attached to the cleaning brush 800 as it rotates, thereby maintaining the cleanliness and working efficiency of the cleaning brush 800 and extending the service life of the cleaning module.

[0123] In some embodiments, the tooth comb 120 also contacts the driving brush 900 , and the tooth comb 120 cleans the driving brush 900 while cleaning the cleaning brush 800 .

[0124] The present application also provides an air conditioner indoor unit, comprising a housing 100 having an air conditioning inlet defined at the top thereof. The air conditioner indoor unit may further include an indoor heat exchanger 200 disposed within the housing 100. The air conditioner indoor unit may further include an indoor fan 300 disposed within the housing 100. Under the action of the indoor fan 300, airflow is input into the housing 100 through the air conditioning inlet, and then, after heat exchange in the indoor heat exchanger 200, is input into the indoor room.

[0125] The air conditioner indoor unit also includes a first rotating rod 400, which is disposed within the housing 100 and located at one end of the air conditioner air inlet in the longitudinal direction. The air conditioner indoor unit may also include a second rotating rod 500, which is disposed within the housing 100 and located at one end of the air conditioner air inlet in the longitudinal direction away from the first rotating rod 400. The air conditioner indoor unit may also include a filter 600, which is annular and is mounted on the first and second rotating rods 400 and 500. The filter 600 is supported by the first and second rotating rods 400 and 500. The filter 600 is divided into two layers, upper and lower, after being supported by the first and second rotating rods 400 and 500. Air entering the housing 100 is filtered by the upper filter 600 and then by the lower filter 600. The filter 600 is capable of rolling on the first and second rotating rods 400 and 500.

[0126] The air conditioner indoor unit further includes a cleaning module, which is disposed in the housing 100. The cleaning module is used to clean the filter 600;

[0127] The air conditioner indoor unit also includes a support frame, which is arranged at the air inlet of the air conditioner; the first rotating rod 400 and the second rotating rod 500 are respectively arranged at both ends of the support frame; the filter 600 is mounted on the first rotating rod 400 and the second rotating rod 500 and is also mounted on the support frame.

[0128] The support frame includes a main frame 701 , and the first rotating rod 400 is disposed at one end of the main frame 701 .

[0129] The support frame further includes a side bracket 702 , which is disposed on an end of the main frame 701 away from the first rotating rod 400 , and the second rotating rod 500 is disposed on an end of the side bracket 702 away from the main frame 701 .

[0130] The side bracket 702 and the main bracket 701 are detachably connected via an elastic bending portion.

[0131] With the above solution, after the filter 600 is mounted on the first rotating rod 400 and the second rotating rod 500, the filter 600 is divided into two layers, and the air is first filtered by the upper filter 600 and then filtered by the lower filter 600. Therefore, there is more impurities and dust on the upper filter 600.

[0132] The driving component drives the filter 600 to roll, and the filter 600 with more dust on the upper layer gradually rolls to the lower layer. At this time, the dust on the filter 600 is cleaned under the action of the cleaning brush 800 to achieve cleaning of the filter 600.

[0133] The ring-shaped filter 600 filters through two layers, providing excellent filtration and reliable operation. It can be cleaned in any state. Furthermore, there is no need to detect the position of the filter 600, eliminating the need for a position sensor, thus saving costs.

[0134] In some embodiments, the side bracket 702 is detachably connected to the main bracket 701, and the angle between the bracket and the main bracket 701 is variable.

[0135] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
