[0042] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0043] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0044] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0045] For ease of description, unless otherwise specified, references to up, down, left, right, front, and back in this disclosure are based on the operating state of the air conditioner indoor unit. The side of the air conditioner indoor unit facing the user is the front side, and the side opposite to it is the back side. The height of the air conditioner indoor unit is the up and down direction. The length of the air conditioner indoor unit is the left and right direction, and the thickness of the air conditioner indoor unit is the front and back direction.

[0046] With the widespread use of air conditioners, users' requirements for them are constantly increasing. The air conditioner indoor unit consists of an air inlet and an air outlet. A filter is installed at the air inlet to filter the air entering the indoor unit, preventing dust and other debris from entering the unit. After the indoor unit has been running for a while, excessive dust and other debris may clog the filter, causing it to partially clog, reducing the air intake and lowering the cooling or heating efficiency of the air conditioner.

[0047] Typically, a roller brush is installed in the air conditioner indoor unit to remove debris attached to the filter, so that the filter maintains a high filtering capacity, thereby maintaining the cooling or heating efficiency of the air conditioner indoor unit. When the air conditioner indoor unit has been in operation for a period of time, a lot of debris will be attached to the filter, and there will be a need to remove the filter assembly to clean the filter and roller brush in the filter assembly. During the process of removing the filter assembly, since the drive motor that drives the filter to move relative to the roller brush is connected to the filter, the drive motor must be removed before the filter assembly can be removed. However, when removing the filter assembly, there is a safety hazard of electric shock due to contact with the drive motor. In addition, the filter assembly is not easy to install and remove, which makes the assembly efficiency of the air conditioner indoor unit low and is not conducive to users cleaning the filter assembly.

[0048] Some embodiments of the present disclosure provide an air-conditioning indoor unit 1000, as shown in Figures 1, 5 and 6, the air-conditioning indoor unit 1000 includes a shell 100, a filter assembly 200, a self-cleaning assembly 300, at least one drive assembly 400 (see Figure 11) and at least one transmission assembly 500 (see Figure 11).

[0049] The housing 100 includes a front panel 191, a back panel 192, a first side panel 193, and a second side panel 194. The front panel 191 is the side panel on the side away from the wall when the air conditioner indoor unit is installed on the indoor wall. The back panel 192 is the side panel on the side closer to the wall when the air conditioner indoor unit is installed on the indoor wall. The first side panel 193 and the second side panel 194 are connected to the front panel 191 and the back panel 192, respectively, and extend in directions perpendicular to the front panel 191 and the back panel 192, respectively. For example, the first side panel 193 is the side panel on one side of the housing 100 in the longitudinal direction (i.e., the left-right direction as shown in Figure 1), and the second side panel 194 is the side panel on the other side of the housing 100 in the longitudinal direction (i.e., the left-right direction as shown in Figure 1). For example, the first side panel 193 is the side panel on the left side of the air conditioner indoor unit 1000, and the second side panel 194 is the side panel on the right side of the air conditioner indoor unit 1000.

[0050] The housing 100 includes an air inlet 110. For example, a portion of the top of the housing 100 is open to form the air inlet 110. The filter assembly 200 is disposed within the housing 100 and is located at the air inlet 110. The filter assembly 200 is configured to filter air entering the air conditioner indoor unit 1000 from the air inlet 110 to prevent foreign matter in the air from entering the air conditioner indoor unit 1000. The self-cleaning assembly 300 is disposed within the housing 100 and is configured to remove foreign matter attached to the filter assembly 200.

[0051] The drive assembly 400 is disposed on the housing 100, and the transmission assembly 500 is disposed within the housing 100. The transmission assembly 500 is respectively connected to the self-cleaning assembly 300 and the drive assembly 400, and is configured to drive the self-cleaning assembly 300 to move under the drive of the drive assembly 400, so that the self-cleaning assembly 300 removes debris attached to the filter assembly 200 to perform a self-cleaning operation, thereby maintaining the cooling or heating efficiency of the air conditioner indoor unit 1000.

[0052] In some embodiments, as shown in Figures 2 and 5, the air conditioner indoor unit 1000 further includes an indoor heat exchanger 600, a fan assembly 700, and an air outlet. The indoor heat exchanger 600 is disposed within the housing 100 and is configured to exchange heat with indoor air entering through the air inlet 110. The fan assembly 700 is disposed on a side of the indoor heat exchanger 600 away from the air inlet 110 and is configured to draw in and pump out indoor air.

[0053] For example, when the fan assembly 700 is in operation, the fan rotates, sucking indoor air in through the air inlet 110, exchanging heat with the indoor heat exchanger 600, and then pumping the indoor air, which has been heat-exchanged by the indoor heat exchanger 600, out through the air outlet. The air conditioner indoor unit 1000 heats or cools the indoor air through the indoor heat exchanger 600, thereby increasing or decreasing the indoor temperature, thereby achieving a heating or cooling effect.

[0054] In some embodiments, as shown in Figures 6, 7A, and 7B, the filter assembly 200 includes a filter 210. The filter 210 is disposed between the air inlet 110 and the indoor heat exchanger 600 (as shown in Figure 5), and covers the air inlet 110, so that the filter 210 can filter foreign matter in the air entering the air conditioner indoor unit 1000 from the air inlet 110.

[0055] The self-cleaning assembly 300 includes a base 310, a first cleaning brush 320, a first reel 330 and a second reel 340. The base 310 is arranged in the housing 100 and includes a mounting member 311 and a bracket 312. One side of the bracket 312 is connected to the side of the mounting member 311 close to the back plate 192 and extends along the thickness direction of the air conditioning indoor unit 1000 (the front-to-back direction as shown in Figure 7A). An installation cavity 313 is defined in the mounting member 311, and a portion of the top of the installation cavity 313 is open. The bracket 312 is configured to carry the filter 210. The filter 210 is arranged on the bracket 312 and can move relative to the bracket 312.

[0056] A first cleaning brush 320, a first reel 330, and a second reel 340 are rotatably disposed within the mounting cavity 313. The first cleaning brush 320, the first reel 330, and the second reel 340 each extend along the length of the air conditioner indoor unit 1000. The first cleaning brush 320 includes a first bristle brush 321 and is configured to remove debris attached to the filter 210. The first cleaning brush 320 is disposed adjacent to the first reel 330. The first reel 330 and the second reel 340 are spaced apart and substantially parallel to each other. One end of the filter 210 is connected to the first reel 330, and the other end is connected to the second reel 340. The filter 210 is wound around the periphery of at least one of the first reel 330 and the second reel 340, with the filter 210 being tensioned between the first reel 330 and the second reel 340.

[0057] 5 , 10 and 11 , the transmission assembly 500 is disposed in the base 310 and is connected to the first reel 330 and the second reel 340 . The transmission assembly 500 is connected to the filter 210 via the first reel 330 and the second reel 340 .

[0058] The drive assembly 400 is disposed on the housing 100 and includes a drive gear 410. The drive gear 410 is connected to the power output terminal. The power output terminal of the drive assembly 400 is detachably connected to the transmission assembly 500. For example, the drive assembly 400 is a drive motor. The drive assembly 400 can drive the first reel 330 and the second reel 340 to rotate in opposite directions through the transmission assembly 500 to drive the filter 210 to move along a predetermined trajectory. In other words, relative motion occurs between the first cleaning brush 320 and the filter 210, so that different areas of the filter 210 are arranged relative to the first cleaning brush 320.

[0059] For example, the drive assembly 400 drives the first reel 330 and the second reel 340 to rotate through the transmission assembly 500, so that the filter 210 is wound on the first reel 330 and unwound on the second reel 340, or the filter 210 is unwound on the first reel 330 and wound on the second reel 340, so that the filter 210 is stretched between the first reel 330 and the second reel 340 and moves relative to the first cleaning brush 320. In this way, the first cleaning brush 320 can clean the area of ​​the filter 210 opposite to it.

[0060] In some embodiments, any of the at least one drive assembly 400 includes a drive motor and a drive gear 410. Any of the at least one transmission assembly 500 includes a first driven gear 510, a second driven gear 520, a third driven gear 530, and an intermediate gear 540. The first driven gear 510 is mounted on one end of the first reel 330 and meshes with the drive gear 410. The second driven gear 520 is mounted on one end of the second reel 340 and meshes with the first driven gear 510. The third driven gear 530 is mounted on one end of the first cleaning brush 320 and meshes with the intermediate gear 540. The first driven gear 510 also meshes with the intermediate gear 540.

[0061] During operation of the self-cleaning assembly 300, the drive assembly 400 operates, causing the drive gear 410 on the power output end to rotate in a first direction, thereby driving the first driven gear 510 to rotate in a second direction, thereby driving the first reel 330 to rotate in the second direction. Simultaneously, the first driven gear 510 also drives the second driven gear 520 to rotate in the first direction, thereby driving the second reel 340 to rotate in the first direction.

[0062] In this way, under the action of the first reel 330 and the second reel 340, the filter 210 stretched between the first reel 330 and the second reel 340 moves along a predetermined trajectory, so that different areas on the filter 210 are opposite to the first cleaning brush 320 in turn, and the first cleaning brush 320 cleans the filter 210 in different areas.

[0063] It should be noted that the first direction is opposite to the second direction. When the first reel 330 rotates along the first direction and reels the filter screen 210 , the second reel 340 rotates along the second direction and unreels the filter screen 210 .

[0064] For example, referring to Figures 7A, 7B, and 11, the first driven gear 510 rotates counterclockwise under the drive gear 410, driving the first reel 330 to rotate counterclockwise to reel in the filter screen 210. Then, while rotating counterclockwise, the first driven gear 510 simultaneously drives the second driven gear 520 to rotate clockwise, thereby driving the second reel 340 to rotate clockwise and unwind the filter screen 210.

[0065] It is understood that the first driven gear 510 rotates clockwise under the drive gear 410, driving the first reel 330 to rotate clockwise to unwind the filter screen 210. Then, the first driven gear 510 rotates clockwise while driving the second driven gear 520 to rotate counterclockwise, thereby driving the second reel 340 to rotate counterclockwise and rewind the filter screen 210.

[0066] In addition, the first driven gear 510 also drives the intermediate gear 540 to rotate along the first direction, so that the intermediate gear 540 drives the third driven gear 530 to rotate along the second direction, and then drives the first cleaning brush 320 to rotate along the second direction, so that the rotation direction of the first cleaning brush 320 is opposite to the movement direction of the filter 210, which is beneficial to improve the cleaning effect of the first cleaning brush 320 on the filter 210.

[0067] For example, the first driven gear 510 and the second driven gear 520 have the same number of teeth, so that the rotation speeds of the first reel 330 and the second reel 340 are consistent, thereby tightening the filter screen 210 on the first reel 330 and the second reel 340 .

[0068] In some embodiments, as shown in Figures 10, 11, and 12, the base 310 further includes a receiving cavity 314. One side of the mounting member 311 along the length of the air conditioner indoor unit 1000 is recessed toward the other side to form the receiving cavity 314. The transmission assembly 500 is disposed within the receiving cavity 314, namely, the first driven gear 510, the second driven gear 520, the third driven gear 530, and the intermediate gear 540 are respectively disposed within the receiving cavity 314. Providing the receiving cavity 314 on the base 310 helps protect and conceal the first driven gear 510, the second driven gear 520, the intermediate gear 540, and the third driven gear 530, facilitates wiring within the air conditioner indoor unit 1000, and prevents operating components (such as the intermediate gear 540) from damaging other components (such as the fan assembly 700 shown in Figure 5).

[0069] In some embodiments, as shown in Figures 7B, 12, and 14, the bottom side of the accommodating cavity 314 is provided with a first opening 3141, a second opening 3142, and a third opening 3143 that communicate with the mounting cavity 313. A first prism 511 is provided in the middle of the first driven gear 510, and a first hole is provided at the end of the first reel 330 to match the first prism 511. The first prism 511 passes through the first opening 3141 and is inserted into the first hole, thereby fixedly connecting the first driven gear 510 to the first reel 330.

[0070] A second prism 521 is provided in the middle of the second driven gear 520. A second hole is provided at the end of the second reel 340 to mate with the second prism 521. The second prism 521 passes through the second opening 3142 and is inserted into the second hole, thereby securely connecting the second driven gear 520 to the second reel 340. A third prism 531 is provided in the middle of the third driven gear 530. A third hole is provided at the end of the first cleaning brush 320 to mate with the third prism 531. The third prism 531 passes through the third opening 3143 and is inserted into the third hole, thereby securely connecting the third driven gear 530 to the first cleaning brush 320.

[0071] The first opening 3141, the first prism 511, the first hole, the second opening 3142, the second prism 521, the second hole, the third opening 3143, the third prism 531 and the third hole are arranged in the air-conditioning indoor unit 1000, which is conducive to realizing the connection between the first driven gear 510 and the first reel 330, the connection between the second driven gear 520 and the second reel 340, and the connection between the third driven gear 530 and the first cleaning brush 320, thereby improving the stability of rotation.

[0072] In this way, the indoor air enters the housing 100 from the air inlet 110 under the action of the fan assembly 700, and flows to the indoor heat exchanger 600 after being filtered by the filter 210. Then, the indoor air is blown out from the air outlet after heat exchange in the indoor heat exchanger 600.

[0073] After the air conditioner indoor unit 1000 has been operating for a period of time, debris in the indoor air, after being filtered by the filter 210, accumulates on the surface of the filter 210, causing a large amount of debris to adhere to the filter 210, thereby affecting the filtering and air intake performance of the filter 210. When a large amount of debris adheres to the filter 210, the self-cleaning assembly 300 of the air conditioner indoor unit 1000 can remove the debris adhered to the filter 210, allowing the filter 210 to maintain its filtering capacity, thereby improving the cooling or heating efficiency of the air conditioner indoor unit 1000.

[0074] In some embodiments, as shown in Figures 8A and 8B , the first reel 330 includes a first portion 331 and a second portion 332, which are detachably connected. The second reel 340 includes a third portion 341 and a fourth portion 342, which are detachably connected. One end of the filter screen 210 is clamped between the first portion 331 and the second portion 332, and the other end of the filter screen 210 is clamped between the third portion 341 and the fourth portion 342.

[0075] It should be noted that the first scroll 330 and the second scroll 340 are respectively set as a two-part structure that can be detachably connected, and the two ends of the filter 210 are respectively fixed to the first scroll 330 and the second scroll 340 by clamping, which can improve the stability of the connection between the filter 210 and the first scroll 330 and the second scroll 340, and is conducive to maintaining the tension of the filter between the first scroll 330 and the second scroll 340.

[0076] The first portion 331, the second portion 332, the third portion 341, and the fourth portion 342 extend along the thickness direction of the air conditioner indoor unit 1000 (the front-to-back direction as shown in Figures 8A and 8B) and have an arcuate cross-section. The outer surfaces of the first portion 331, the second portion 332, the third portion 341, and the fourth portion 342 are smooth, which facilitates the winding and unwinding of the filter 210 on the first reel 330 and the second reel 340.

[0077] A first snap-fit ​​portion 333 is provided on the inner side of the first portion 331, and a second snap-fit ​​portion 334 is provided on the inner side of the second portion 332. The first snap-fit ​​portion 333 and the second snap-fit ​​portion 334 are snap-fitted together, allowing the first portion 331 and the second portion 332 to be detachably connected. A third snap-fit ​​portion 343 is provided on the inner side of the third portion 341, and a fourth snap-fit ​​portion 344 is provided on the inner side of the fourth portion 342. The third snap-fit ​​portion 343 and the fourth snap-fit ​​portion 344 are snap-fitted together, allowing the third portion 341 and the fourth portion 342 to be detachably connected. In this way, the snap-fit ​​connection between the first portion 331 and the second portion 332, and between the third portion 341 and the fourth portion 342, facilitates the user's removal of the filter 210 for cleaning.

[0078] In some embodiments, referring to Figures 2, 9, 10, and 15, an air conditioner indoor unit 1000 includes multiple filter assemblies 200 and multiple self-cleaning assemblies 300. The housing 100 includes multiple air inlets 110. Each filter assembly 200 corresponds to a self-cleaning assembly 300, and each air inlet 110 corresponds to a filter assembly 200.

[0079] It can be understood that the provision of multiple air inlets 110, multiple filter components 200 and multiple self-cleaning components 300 in the air-conditioning indoor unit 1000 is beneficial to increasing the air intake and air output of the air-conditioning indoor unit 1000, thereby improving the cooling or heating efficiency of the air-conditioning indoor unit 1000.

[0080] The air conditioning indoor unit 1000 further includes multiple drive assemblies 400 and multiple transmission assemblies 500, with each drive assembly 400 corresponding to a transmission assembly 500. Each drive assembly 400 is connected to the filter assembly 200 via its corresponding transmission assembly 500. In this way, each filter assembly 200 can be driven independently to perform self-cleaning operations.

[0081] In some embodiments, as shown in Figures 13 and 14, the air conditioning indoor unit 1000 further includes at least one connecting rod 550, the multiple transmission assemblies 500 are connected by the connecting rod 550, and the power output end of the drive assembly 400 is connected to the connecting rod 550. In this way, the drive assembly 400 can drive the multiple self-cleaning assemblies 300 to operate via the connecting rod 550 and the multiple transmission assemblies 500, which helps to simplify the structure of the air conditioning indoor unit 1000.

[0082] In some embodiments, as shown in Figures 5, 11, and 12, the base 310 further includes a notch 315. For example, the side of the accommodating cavity 314 near the back plate 192 is open to form the notch 315. A portion of the first driven gear 510 extends from the notch 315, and the driving gear 410 meshes with the portion of the first driven gear 510.

[0083] It will be appreciated that the removable connection between the transmission assembly 500 and the drive assembly 400 is achieved through the meshing between the first driven gear 510 and the drive gear 410. The notch 315 provided on the base 310 facilitates meshing between the drive gear 410 and the first driven gear 510. When the transmission assembly 500 is disassembled, the first driven gear 510 can be removed from the housing 100 along with the mounting member 311, while the drive gear 410 remains.

[0084] That is, since the power output end of the drive assembly 400 is detachably connected to the transmission assembly 500, and the transmission assembly 500 is connected to the self-cleaning assembly 300, and the filter assembly 200 is connected to the self-cleaning assembly 300, when the user needs to remove the filter assembly 200 and the self-cleaning assembly 300 for cleaning, the base 310 can be removed from the housing 100 to remove the self-cleaning assembly 300 from the housing 100. At the same time, the transmission assembly 500 is removed from the housing 100 along with the self-cleaning assembly 300, while the drive assembly 400 is not removed from the housing 100 along with the transmission assembly 500.

[0085] In this way, the user can disassemble the filter assembly 200 and the self-cleaning assembly 300 without touching the drive assembly 400, and clean the filter assembly 200 and the self-cleaning assembly 300, thereby avoiding safety hazards caused by contact with the drive assembly 400. In addition, the drive assembly 400 is hidden in the housing 100, which helps to protect it from damage by external factors.

[0086] In some embodiments, as shown in Figure 2, the housing 100 further includes a through hole 120 and a mounting slot 130. For example, a portion of the front side of the housing 100 is open to form the through hole 120. The housing 100 defines a mounting slot 130. The front side of the mounting slot 130 is open. The through hole 120 is connected to the mounting slot 130, and the through hole 120 is located above the mounting slot 130. The mounting member 311 is disposed in the mounting slot 130. The self-cleaning assembly 300 is disposed on the inner side of the mounting member 311, and the transmission assembly 500 is disposed on the outer side of the mounting member 311. The bracket 312 is disposed in the housing 100 through the through hole 120.

[0087] Because the first reel 330, the second reel 340, and the first cleaning brush 320 are disposed within the mounting member 311, which is disposed within the mounting slot 130, and one side of the bracket 312 is connected to the mounting member 311 and extends rearward through the through hole 120, the user can remove the mounting member 311 from the mounting slot 130 through the through hole 120, thereby removing the bracket 312 and the filter screen 210 from the housing 100 along with the mounting member 311, thereby removing the filter assembly 200 and the self-cleaning assembly 300. This reduces the difficulty of removing and installing the filter assembly 200 and the self-cleaning assembly 300, making it easier for the user to clean the removed filter assembly 200 and the self-cleaning assembly 300.

[0088] Similarly, the user can install the mounting member 311 in the mounting groove 130 through the through hole 120, so that the bracket 312 and the filter screen 210 are installed in the housing 100 together with the mounting member 311, thereby installing the filter assembly 200 and the self-cleaning assembly 300.

[0089] 9 , the air conditioner indoor unit 1000 further includes a stopper 160. The stopper 160 is rotatably mounted on the front plate 191 of the housing 100 and adjacent to the mounting slot 130. The stopper 160 is configured to rotate and switch between a locked position and an unlocked position.

[0090] For example, when the stop block 160 is in the locked position, at least a portion of the stop block 160 is located on the front side of the mounting member 311 to prevent the mounting member 311 from sliding out of the mounting slot 130. When the stop block 160 is in the unlocked position, the stop block 160 is located on the front plate 191 of the housing 100 to allow the mounting member 311 to slide forward and out of the mounting slot 130.

[0091] It should be noted that when the air conditioner indoor unit 1000 is working, the stop block 160 is in the locked position to prevent the mounting member 311 from sliding out of the mounting slot 130. When the filter assembly 200 needs to be cleaned, the stop block 160 is rotated to the unlocked position and the mounting member 311 can be removed.

[0092] For example, the air conditioner indoor unit 1000 includes a plurality of stoppers 160. The plurality of stoppers 160 are provided on the housing 100 to facilitate the user in removing and installing the filter assembly 200.

[0093] In some embodiments, as shown in Figures 5 and 15, the self-cleaning assembly 300 further includes a dust box 350 and a dust box 360. The dust box 350 is disposed on the base 310 and is located below the first cleaning brush 320. The dust box 350 is configured to collect debris removed from the filter 210.

[0094] As shown in Figures 3 and 10, the air conditioning indoor unit 1000 also includes a slot 150. The slot 150 is provided on the front plate 191 of the housing 100. The ash box 360 is provided in the slot 150, and the ash box 360 is located below the dust box 350. The slot 150 has a first side wall 151 and a second side wall 152 that are spaced apart along the length direction of the air conditioning indoor unit 1000 (i.e., the left and right direction in Figure 9). The first side wall 151 is provided with a first card slot 153, and the second side wall 152 is provided with a second card slot 154. As shown in Figure 12, the ash box 360 is provided with a first card block and a second card block that are spaced apart along the length direction of the air conditioning indoor unit 1000 (i.e., the left and right direction in Figure 9).

[0095] The ash box 360 is detachably installed in the slot 150 through the cooperation between the first clamping block and the first clamping slot 153 , and the cooperation between the second clamping block and the second clamping slot 154 .

[0096] In some embodiments, as shown in Figures 15 and 16, the self-cleaning assembly 300 further includes a second cleaning brush 370. The second cleaning brush 370 is disposed in the dust box 350 and is configured to remove debris attached to the first cleaning brush 320 into the dust box 350. The second cleaning brush 370 includes a second brush 371, which is configured to be inserted into the first cleaning brush 320.

[0097] When the self-cleaning component is working, some debris will adhere to the first brush 321. The second brush 371 can brush the debris attached to the first brush 321 into the dust collection box 350, so that the first brush 321 can contact the filter 210 without being attached to the debris and remove the debris attached to the filter 210, which is beneficial to improving the effect of cleaning the filter 230.

[0098] In some embodiments, as shown in Figures 1 and 4, the air conditioning indoor unit 1000 further includes a panel 800. The panel 800 is detachably connected to the front side of the housing 100 to block the through-hole 120. For example, when the air conditioning indoor unit 1000 is in operation, the panel 800 is placed on the front side of the housing 100 to enhance the appearance of the air conditioning indoor unit 100. When it is necessary to remove and clean the filter assembly 200 and the self-cleaning assembly 300, the panel 800 can be removed from the front side of the housing 100, and then the filter assembly 200 and the self-cleaning assembly 300 can be removed from the housing 100 through the through-hole 120.

[0099] As shown in Figure 2, a first matching portion is provided on the inner side surface of the panel 800, and a second matching portion 140 is provided on the front side of the shell 100. The first matching portion and the second matching portion 140 are connected by a snap so that the panel 800 can be detachably connected to the front side of the shell 100.

[0100] In some embodiments, as shown in FIG17 , the filter 210 includes a filter portion 211 and a blocking portion 212 connected in sequence. The filter portion 211 is configured to filter the air entering the housing 100 from the air inlet 110, and the blocking portion 212 is configured to block the air entering the housing 100 from the air inlet 110.

[0101] For example, when the filter 210 moves along a predetermined trajectory, the filter 210 can move between a filtering position and a blocking position. When the filter 210 is in the filtering position, the filter portion 211 covers the air inlet 110, filtering the air entering the housing 100 from the air inlet 110. When the filter 210 is in the blocking position, the blocking portion 212 covers the air inlet 110, blocking the air entering the housing 100 from the air inlet 110.

[0102] It should be noted that when the air conditioner indoor unit 1000 is operating, the filter 210 is in the filtering position, the filter portion 211 covers the air inlet 110, and filters the air entering through the air inlet 110. When the air conditioner indoor unit is stopped, the filter 210 moves from the filtering position to the blocking position, and the blocking portion 212 covers the air inlet 110, so that air and dust are blocked by the blocking portion 212, preventing dust from entering the interior of the housing 100.

[0103] It is understood that the filter portion 211 is a region having multiple small pores. These pores can filter large particles of dust and other impurities from the air, allowing the filtered air to enter the housing 100. The blocking portion 212 is a non-porous region that prevents air and dust from passing through. For example, the blocking portion 212 is made of a plastic film, and a hot-melt portion is provided between the blocking portion 212 and the filter portion 211 to connect the two portions.

[0104] In this way, by setting a sealing portion 212 in the filter 210, air and dust cannot enter the shell 100 when the air-conditioning indoor unit 1000 is shut down, thereby preventing dust and other debris from entering the interior of the shell 100, and preventing dust and other debris from adhering to the indoor heat exchanger 600 or the fan assembly 700 in the shell 100, making the interior of the air-conditioning indoor unit 1000 cleaner, which is beneficial to improving the cooling or heating effect of the air-conditioning indoor unit 1000.

[0105] In some embodiments, the air conditioner indoor unit 1000 further includes a sensor and a controller. The sensor is configured to send a signal to the controller indicating the start of a self-cleaning mode. For example, the signal instructs the air conditioner indoor unit 1000 to start or stop the self-cleaning mode. When the amount of debris on the filter 210 reaches a preset level, the sensor sends a signal to the controller indicating the start of the self-cleaning mode. When the amount of debris on the filter 210 falls below a preset level, the sensor sends a signal to the controller indicating the stop of the self-cleaning mode.

[0106] The controller is configured to receive a signal from the sensor and, in response to the signal, control the air conditioner indoor unit 1000 to perform an operation indicated by the signal. For example, upon receiving a signal from the sensor indicating that the self-cleaning mode is to be executed, the controller controls the air conditioner indoor unit 1000 to execute the self-cleaning mode. Upon receiving a signal from the sensor indicating that the self-cleaning mode is to be stopped, the controller controls the air conditioner indoor unit 1000 to stop the self-cleaning mode.

[0107] For example, after the air conditioner indoor unit 1000 has been operating for a period of time, indoor air continuously flows from the air inlet 110 to the indoor heat exchanger 600 under the action of the fan assembly 700. After heat exchange in the indoor heat exchanger 600, it is delivered to the indoor room through the air outlet by the fan assembly 700. As a result, the amount of debris attached to the filter 210 opposite the air inlet 110 in the air conditioner indoor unit 1000 increases. When the amount of debris on the filter 210 reaches a predetermined level, the sensor sends a signal to the controller indicating that the self-cleaning mode is activated.

[0108] The controller receives a signal from the sensor indicating the self-cleaning mode is in operation and controls the air conditioner indoor unit 1000 to operate in the self-cleaning mode. When in the self-cleaning mode, the drive assembly 400 drives the first reel 330 and the second reel 340 to rotate in opposite directions via the transmission assembly 500, thereby driving the filter 210 along a predetermined trajectory. The first cleaning brush 320 can be positioned opposite different areas of the filter 210 and clean the area of ​​the filter 210 opposite to the first cleaning brush 320.

[0109] When the first reel 330 and the second reel 340 rotate in opposite directions, the first cleaning brush 320 contacts the first reel 330 to remove debris from the filter 210 wound on the first reel 330, causing the debris to fall into the dust box 350 for collection. When the dust box 350 contains a lot of debris, the dust box 350 can be removed for cleaning.

[0110] Some embodiments of the present disclosure provide another air-conditioning indoor unit 100A. As shown in FIG18 , the air-conditioning indoor unit 100A includes a shell 10, an indoor heat exchanger 20, a fan assembly 30, at least one filter 40, at least one self-cleaning assembly 50, at least one drive assembly 60, and at least one transmission assembly 70.

[0111] As shown in Figures 19 to 21, the housing 10 includes a front panel 12, a back panel 13, a first side panel 14, and a second side panel 15. The front panel 12 is the side panel facing away from the wall when the air conditioner indoor unit is mounted on a room wall. The back panel 13 is the side panel facing closer to the wall when the air conditioner indoor unit is mounted on a room wall. The first side panel 14 and the second side panel 15 connect the front panel 12 and the back panel 13, respectively, and extend perpendicularly to the front panel 12 and the back panel 13, respectively.

[0112] For example, the first side panel 14 is a side panel on one side in the longitudinal direction of the housing 10 (i.e., the left-right direction as shown in FIG19 ), and the second side panel 15 is a side panel on the other side in the longitudinal direction of the housing 10. For example, the first side panel 14 is a side panel on the left side of the air conditioning indoor unit 100A, and the second side panel 15 is a side panel on the right side of the air conditioning indoor unit 100A.

[0113] The housing 10 includes at least one air inlet 11 and an air outlet. A portion of the top of the housing 10 is open to form the air inlet 11. For example, as shown in FIG19 , the housing 10 includes two air inlets 11, each disposed at the top of the housing 10 and spaced apart along the length of the housing 10.

[0114] A portion of the bottom of the housing 10 is open to form the air outlet. The indoor heat exchanger 20 is disposed within the housing 10 and is configured to exchange heat with the indoor air entering through the air inlet 11. The fan assembly 30 is disposed on a side of the indoor heat exchanger 20 away from the air inlet 11 and is configured to inhale and pump out the indoor air. For example, when the fan assembly 30 is in operation, the fan rotates, inhaling indoor air from the air inlet 11, causing the indoor air to exchange heat with the indoor heat exchanger 20, and then pumping the indoor air that has exchanged heat with the indoor heat exchanger 20 out of the air outlet.

[0115] It is understood that indoor air enters the housing 10 through the air inlet 11 under the action of the fan assembly 30, and enters the indoor heat exchanger 20 for heat exchange after being filtered by the filter 40. For example, when the air conditioner indoor unit 100A is cooling, the indoor air is converted into cold air after heat exchange with the indoor heat exchanger 20 and blown into the room through the air outlet.

[0116] It should be noted that the fan assembly 30 can guide indoor air from the air inlet 11 to the indoor heat exchanger 20, increase the air intake from the air inlet 11 into the indoor heat exchanger 20, and the fan assembly 30 can adjust the air intake into the indoor heat exchanger 20.

[0117] The filter 40 is disposed between the air inlet 11 and the indoor heat exchanger 20 and covers the air inlet 11. The filter 40 is configured to filter air entering the air conditioner indoor unit 100A from the air inlet 11 to prevent foreign matter in the air from entering the air conditioner indoor unit 100A.

[0118] For example, when the air conditioner indoor unit 100A is in operation, indoor air entering the housing 10 through the air inlet 11 first passes through the filter 40 and then enters the indoor heat exchanger 20 after being filtered by the filter 40. This prevents debris in the indoor air from entering the indoor heat exchanger 20 and accumulating on the indoor heat exchanger 20 to prevent it from clogging and reducing the heat exchange efficiency of the indoor heat exchanger 20. After heat exchange in the indoor heat exchanger 20, the indoor air is blown out of the air outlet by the fan assembly 30.

[0119] The self-cleaning assembly 50 is disposed within the housing 10 and is configured to clean debris attached to the filter 40. A drive assembly 60 is disposed on the housing 10, and a transmission assembly 70 is disposed within the housing 10. The drive assembly 60 is configured to drive the transmission assembly 70 to rotate. The transmission assembly 70 is connected to the self-cleaning assembly 50 and the drive assembly 60, and is configured to drive the self-cleaning assembly 50 to move under the drive of the drive assembly 60, so that the self-cleaning assembly 50 cleans debris attached to the filter 40, thereby maintaining the cooling or heating efficiency of the air conditioner indoor unit 100A.

[0120] In some embodiments, as shown in Figure 23, the self-cleaning assembly 50 includes a base 51, a first reel 52, a second reel 53, a cleaning brush assembly 54 and a dust box 55. The base 51 is arranged in the shell 10 and is close to the front plate 12. The base 51 includes a base body 511A and a bracket 512. One side of the bracket 512 is connected to a side of the base body 511A close to the back plate 13 and extends along the thickness direction of the shell 10 (i.e., the front and rear direction as shown in Figure 19). The bracket 512 is configured to carry the filter 40. The filter 40 is arranged on the bracket 512 and can move along a predetermined trajectory on the bracket 512.

[0121] The first reel 52, the second reel 53, and the cleaning brush assembly 54 are rotatably connected to the base body 511A, and the first reel 52, the second reel 53, and the cleaning brush assembly 54 extend along the length of the housing 10. The second reel 53 is spaced apart from the first reel 52 and is substantially parallel to the first reel 52. One end of the filter screen 40 is connected to the second reel 53, and the other end is connected to the first reel 52. The filter screen 40 is wound around the outer periphery of at least one of the second reel 53 and the first reel 52, and the filter screen 40 is tensioned between the second reel 53 and the first reel 52. The cleaning brush assembly 54 is disposed near the first reel 52 and is configured to clean debris on the filter screen 40 while the first reel 52 is winding or unwinding the filter screen 40.

[0122] The self-cleaning assembly 50 also includes a cleaning chamber 56. The cleaning chamber 56 is defined within the base body 511A. The cleaning chamber 56 includes a first opening 563 and a second opening 564. The top of the cleaning chamber 56 is open to form the first opening 563, and the bottom of the cleaning chamber 56 is open to form the second opening 564. The second reel 53 is located above the first opening 563, the first reel 52 is located at the first opening 563, and the cleaning brush assembly 54 is located in the cleaning chamber 56. The dust box 55 is arranged below the second opening 564 and is configured to accommodate debris cleaned from the filter 40 by the cleaning brush assembly 54.

[0123] In some embodiments, the second reel 53 and the first reel 52 rotate in opposite directions. During the cleaning process of the self-cleaning assembly 50, the filter 40 is wound on the first reel 52 and unwound on the second reel 53, or the filter 40 is unwound on the first reel 52 and wound on the second reel 53. At least a portion of the cleaning brush assembly 54 is in contact with the filter 40, and as the filter 40 is wound and unwound, the cleaning brush assembly 54 and the filter 40 generate relative motion. The cleaning brush assembly 54 can be arranged relative to different areas of the filter 40 and can clean different areas of the filter 40. The debris on the filter 40 is cleaned into the dust box 55 by the cleaning brush assembly 54.

[0124] In some embodiments, as shown in Figures 21 and 24, the cleaning brush assembly 54 includes a cleaning brush base 541, a cleaning brush 542, and at least one elastic member 543. The cleaning brush 542 is disposed on the cleaning brush base 541. The cleaning brush base 541 includes a first mounting portion 5411 and a second mounting portion 5412. The first mounting portion 5411 is disposed on and connected to the second mounting portion 5412. One end of any one of the at least one elastic member 543 abuts the first mounting portion 5411, and the other end abuts the second mounting portion 5412.

[0125] For example, the elastic member 543 is a spring. The cleaning brush 542 is disposed on a side of the first mounting portion 5411 away from the second mounting portion 5412. When the cleaning brush 542 abuts the first reel 52, the first reel 52 applies a force to the cleaning brush 542, thereby applying a force to the first mounting portion 5411, causing the first mounting portion 5411 to compress the elastic member 543.

[0126] Because the second mounting portion 5412 is stationary along the height direction of the housing 10 (i.e., the vertical direction as shown in FIG19 ), the elastic member 543 applies an elastic force of equal magnitude and opposite direction to the first mounting portion 5411, causing the cleaning brush 542 to apply force to the first reel 52, thereby elastically abutting the cleaning brush 542 against the first reel 52. The cleaning brush base 541, through the elastic member 543, abuts the cleaning brush 542 against the first reel 52. This facilitates ensuring that the cleaning brush 542 always abuts the first reel 52 during rotation of the first reel 52 or the cleaning brush base 541, thereby improving the cleaning ability of the cleaning brush 542 on the filter 40 wound on the first reel 52. Furthermore, this prevents excessive wear of the cleaning brush 542 due to hard contact between the first reel 52 and the cleaning brush 542, thereby extending the service life of the cleaning brush 542.

[0127] It is understood that the cleaning brush 542 is in contact with the first reel 52 via the elastic member 543. When the second reel 53 and the first reel 52 rotate in opposite directions, the cleaning brush 542 can contact the first reel 52 and clean the filter 40 at the contact point, causing debris brushed off the filter 40 to fall into the dust box 55 for collection. Since the first reel 52 may generate vibration or radial runout during rotation, the elasticity of the elastic member 543 helps to improve the stability of the contact between the cleaning brush 542 and the first reel 52, avoiding hard contact between the first reel 52 and the cleaning brush 542.

[0128] For example, after the air conditioner indoor unit 100A has been operating for a period of time, indoor air continuously enters the indoor heat exchanger 20 under the action of the fan assembly 30, is heated by the indoor heat exchanger 20, and is then delivered indoors. After the indoor air entering the indoor heat exchanger 20 is filtered by the filter 40, impurities in the indoor air may accumulate on the surface of the filter 40, increasing the amount of impurities attached to the filter 40 and affecting the filtering and air intake performance of the filter 40.

[0129] When the filter 40 is clogged with debris, the air conditioner indoor unit 100A can operate in a self-cleaning mode to remove debris from the filter 40, maintaining its filtering capacity and improving the cooling or heating efficiency of the air conditioner indoor unit 100A. When the air conditioner indoor unit 100A operates in self-cleaning mode, the second reel 53 and the first reel 52 rotate, causing the filter 40 to reel on the second reel 53 and unreel on the first reel 52, or vice versa. The filter 40 unreeled on the second reel 53 and reeled on the first reel 52. The second reel 53 and the first reel 52 cause the filter 40 to move relative to the cleaning brush 542, causing the cleaning brush 542 to be positioned opposite different areas of the filter 40 and clean those areas.

[0130] In some embodiments, as shown in Figures 20, 21, and 25, the dust box 55 includes a dust box body 551 and a latch hole 553. The latch hole 553 is provided at one end of the dust box body 551 along the length direction of the housing 10. The housing 10 further includes a positioning member provided on a side panel of the housing 10 along the length direction. The dust box 55 is engaged with the housing 10 through the latch hole 553 and the positioning member to achieve a detachable connection between the dust box 55 and the housing 10. When it is necessary to clean debris in the dust box 55, the dust box 55 can be removed from the housing 10 through the latch hole 553 and the positioning member to clean the debris in the dust box 55.

[0131] As shown in FIG25 , the dust box 55 further includes a baffle 552. The baffle 552 is disposed on the front side of the dust box body 551. One end of the baffle 552 is connected to the dust box body 551, and the other end of the baffle 552 extends upward in the height direction of the housing 10 (i.e., the vertical direction as shown in FIG19 ). The baffle 552 is configured to seal the gap between the front side of the dust box 55 and the front surface of the base 51 when the dust box 55 is assembled with the base 51, thereby preventing debris in the dust box 55 from spilling out of the gap.

[0132] In some embodiments, as shown in Figure 24, the cleaning brush assembly 54 also includes a mounting cavity 544. The side of the second mounting portion 5412 facing the cleaning brush 542 is open, and the first mounting portion 5411 is arranged on the open side of the second mounting portion 5412. The first mounting portion 5411 and the second mounting portion 5412 together define the mounting cavity 544. The elastic member 543 is arranged in the mounting cavity 544. Since the two ends of the elastic member 543 are respectively abutted against the first mounting portion 5411 and the second mounting portion 5412, when the first mounting portion 5411 is squeezed, the first mounting portion 5411 can move toward the second mounting portion 5412. In this way, the provision of the mounting cavity 544 in the cleaning brush assembly 54 is conducive to the installation of the elastic member 543 and prevents the elastic member 543 from falling off the cleaning brush base 541.

[0133] In some embodiments, as shown in FIG24 , the cleaning brush assembly 54 further includes at least one positioning post 545 . Any one of the at least one positioning post 545 is disposed on either the first mounting portion 5411 or the second mounting portion 5412 . The elastic member 543 is sleeved on any one of the positioning posts 545 .

[0134] Taking the example of a cleaning brush assembly 54 comprising two positioning posts 545 and two elastic members 543, with the two positioning posts 545 disposed on the second mounting portion 5412, the two positioning posts 545 are disposed at both ends of the second mounting portion 5412 along the length of the housing 10. The elastic members 543 are respectively sleeved onto the positioning posts 545. Thus, providing the positioning posts 545 in the cleaning brush assembly 54 facilitates the positioning and installation of the elastic members 543, allowing the elastic members 543 to move along the height direction of the housing 10, thereby causing the first mounting portion 5411 to drive the cleaning brush 542 to move relative to the second mounting portion 5412.

[0135] In some embodiments, as shown in FIG24 , the cleaning brush base 541 further includes at least one slot 5414 and at least one buckle 5415. The at least one slot 5414 is disposed on at least one of the two side walls of the first mounting portion 5411 along the width direction of the housing 10. The at least one buckle 5415 is disposed on at least one of the two side walls of the second mounting portion 5412 along the width direction of the housing 10. The buckle 5415 and the slot 5414 engage with each other to connect the first mounting portion 5411 to the second mounting portion 5412. When the buckle 5415 is engaged in the slot 5414, the buckle 5415 can move within the slot 5414 along the height direction of the housing 10.

[0136] For example, when at least one first mounting portion 5411 includes a plurality of slots 5414, the plurality of slots 5414 are spaced apart on both side walls of the first mounting portion 5411 along the width direction of the housing 10. Corresponding to the plurality of slots 5414, a plurality of latches 5415 are provided on both side walls of the second mounting portion 5412 along the width direction of the housing 10, and the plurality of latches 5415 are spaced apart along the length direction of the housing 10.

[0137] When the first mounting portion 5411 and the second mounting portion 5412 are engaged with each other, the plurality of slots 5414 and the plurality of buckles 5415 are engaged with each other to achieve the installation of the first mounting portion 5411 and the second mounting portion 5412 .

[0138] For example, the length of the slot 5414 along the height direction of the shell 10 is greater than the length of the buckle 5415 along the height direction of the shell 10, so that the first mounting portion 5411 can move relative to the second mounting portion 5412 along the height direction of the shell 10.

[0139] It is understood that when the cleaning brush 542 abuts the first reel 52, the first mounting portion 5411 moves toward the second mounting portion 5412. When the cleaning brush 542 separates from the first reel 52, the first mounting portion 5411 moves away from the second mounting portion 5412. Thus, the first mounting portion 5411 and the second mounting portion 5412 are engaged and connected via the slot 5414 and the buckle 5415, which helps improve the assembly efficiency of the first mounting portion 5411 and the second mounting portion 5412, simplifies the structure of the cleaning brush base 541, and improves the stability of the assembly of the first mounting portion 5411 and the second mounting portion 5412.

[0140] Moreover, when the buckle 5415 is engaged in the slot 5414, the buckle 5415 can move relative to the slot 5414, which is conducive to the movement of the first mounting part 5411 relative to the second mounting part 5412, so that the cleaning brush 542 abuts against the first reel 52, thereby improving the efficiency of the cleaning brush 542 in cleaning the filter 40.

[0141] In some embodiments, as shown in Figures 23 to 25, the first mounting portion 5411 includes a first side portion 5416, a second side portion 5417, and a connecting portion 5413. The connecting portion 5413 has two ends along the thickness direction of the housing 10 that connect to the upper sides of the first side portion 5416 and the second side portion 5417, respectively. The lower sides of the first side portion 5416 and the second side portion 5417 extend toward the second mounting portion 5412 along the height direction of the housing 10. The first side portion 5416, the second side portion 5417, and the connecting portion 5413 collectively constitute the first mounting portion 5411.

[0142] The first side portion 5416 and the second side portion 5417 extend toward the second mounting portion 5412. One end of the elastic member 543 abuts against the connecting portion 5413, and the other end of the elastic member 543 is sleeved on the positioning post 545 provided on the second mounting portion 5412. The first side portion 5416 and the second side portion 5417 are connected to the second mounting portion 5412 through the engagement of the slot 5414 and the buckle 5415. When the first mounting portion 5411 and the second mounting portion 5412 are assembled, the first side portion 5416 and the second side portion 5417 are located outside the two side walls of the second mounting portion 5412 along the thickness direction of the housing 10, thereby limiting the second mounting portion 5412 and preventing the elastic member 543 from falling out.

[0143] A first side portion 5416, a second side portion 5417 and a connecting portion 5413 are provided in the cleaning brush base 541 to constitute a first mounting portion 5411, so that the first mounting portion 5411 has good structural strength, which is beneficial to the installation of the first mounting portion 5411 and the cleaning brush 542, making the installation of the cleaning brush 542 more secure and preventing the cleaning brush 542 from falling off the cleaning brush base 541.

[0144] In some embodiments, as shown in Figures 24 and 25, the self-cleaning component 50 further includes a mounting groove 57. The mounting groove 57 is provided on the side of the connecting portion 5413 away from the second mounting portion 5412. The cleaning brush 542 is provided in the mounting groove 57. The bottom surface of the mounting groove 57 is flush with the surface of the side of the cleaning brush 542 close to the first reel 52 and is arc-shaped, so that when the cleaning brush 542 abuts against the first reel 52, it can clean the filter 40 and allow debris generated by cleaning to fall from the surface of the cleaning brush 542 into the cleaning chamber 56. In this way, providing the mounting groove 57 in the self-cleaning component 50 is conducive to the installation of the cleaning brush 542, improves the stability of the installation of the cleaning brush 542, and increases the position limiting effect of the first mounting portion 5411 on the cleaning brush 542.

[0145] In some embodiments, as shown in Figures 21, 22, and 25, the self-cleaning assembly 50 is connected to two transmission assemblies 70. The drive assembly 60 is connected to either of the two transmission assemblies 70. The two transmission assemblies 70 are respectively arranged at both ends of the self-cleaning assembly 50 along the length direction of the housing 10. The drive assembly 60 is arranged at one end of the housing 10 along the length direction of the housing 10.

[0146] The transmission assembly 70 includes a first gear 71, a second gear 72, and a third gear 73. The first gear 71 meshes with the second gear 72. In the two transmission assemblies 70, the two first gears 71 are respectively disposed at both ends of the second reel 53, the two second gears 72 are respectively disposed at both ends of the first reel 52, and the two third gears 73 are respectively disposed at both ends of the cleaning brush base 541.

[0147] The drive assembly 60 includes a first drive motor 61 and a second drive motor 62. The first drive motor 61 is connected to one of the first gear 71 and the second gear 72 and is configured to drive the rotation of the first gear 71 and the second gear 72. The second drive motor 62 is connected to the third gear 73 and is configured to drive the third gear 73 to rotate.

[0148] Taking the connection between the first drive motor 61 and the second gear 72 as an example, when the self-cleaning assembly 50 is in self-cleaning mode, the first drive motor 61 drives the second gear 72 to rotate in the first direction, thereby driving the first reel 52 to rotate in the first direction. Simultaneously, the second gear 72 also drives the first gear 71 to rotate in the second direction, thereby driving the second reel 53 to rotate in the second direction. The second drive motor 62 drives the third gear 73 to rotate, thereby driving the cleaning brush base 541 to rotate.

[0149] It should be noted that the first direction is opposite to the second direction. When the second reel 53 rotates along the second direction and unwinds the filter screen 40 , the first reel 52 rotates along the first direction and rewinds the filter screen 40 .

[0150] In this way, under the action of the second reel 53 and the first reel 52 , the filter screen 40 tensioned between the second reel 53 and the first reel 52 moves along a predetermined trajectory, so that the cleaning brush 542 and the filter screen 40 move relative to each other, so that the cleaning brush 542 can clean the filter screen 40 .

[0151] It is understood that both ends of the second reel 53 are connected to the first gear 71, and the second reel 53 is rotationally connected to the base 51 via the first gear 71. Both ends of the first reel 52 are connected to the second gear 72, and the first reel 52 is rotationally connected to the base 51 via the second gear 72. Both ends of the cleaning brush base 541 are connected to the third gear 73, and the cleaning brush base 541 is rotationally connected to the base 51 via the third gear 73.

[0152] In some embodiments, as shown in Figures 20 to 22, the air conditioning indoor unit 100A includes two self-cleaning assemblies 50, two drive assemblies 60, and four transmission assemblies 70. One self-cleaning assembly 50, one drive assembly 60, and two transmission assemblies 70 constitute a self-cleaning device, that is, the air conditioning indoor unit 100A includes two self-cleaning devices. The two self-cleaning assemblies 50 are spaced apart along the length of the housing 10.

[0153] Taking a self-cleaning device as an example, the self-cleaning assembly 50 is connected to two transmission assemblies 70, and the two transmission assemblies 70 are respectively arranged at both ends of the self-cleaning assembly 50. The drive assembly 60 is connected to the transmission assembly 70 near the side wall of the housing 10. The drive assembly 60 drives the transmission assembly 70 to rotate, thereby driving the self-cleaning assembly 50 to rotate.

[0154] Since the transmission assemblies 70 are respectively provided at both ends of the two self-cleaning assemblies 50 , it is not necessary to distinguish between left and right when installing the self-cleaning assemblies 50 and the housing 10 , which is beneficial to improving the installation efficiency of the self-cleaning assemblies 50 .

[0155] In some embodiments, as shown in Figure 26, the drive assembly 60 further includes a housing portion 63 and a bending portion 64. The housing portion 63 is connected to the housing 10. The bending portion 64 is arranged on one side of the housing portion 63 along the width direction of the housing 10, and the free end of the bending portion 64 extends toward the base 51 along the length direction of the housing 10. The bending portion 64, the housing portion 63 and the base 51 define a storage space, and the first drive motor 61 and the second drive motor 62 are arranged in the storage space. In this way, it is helpful to reduce the entry of moisture or dust in the air into the storage space, thereby avoiding damage to the first drive motor 61 and the second drive motor 62, and extending the service life of the drive assembly 60.

[0156] In some embodiments, as shown in Figures 25, 26 and 27, the base body 511A includes two end covers 514 and a connecting plate 516. The two end covers 514 are respectively arranged at both ends of the base 51 along the length direction of the shell 10. The connecting plate 516 connects the two end covers 514 and is located on the side of the two end covers away from the back plate 13. The connecting plate 516 includes a gripping portion 5161, which is arranged at the top of the connecting plate 516. The gripping portion 5161 includes a plurality of grooves, which are recessed toward the dust box 55 along the height direction of the shell 10. The plurality of grooves are continuously arranged on the connecting plate 516 along the length direction of the shell 10. In this way, it is convenient for the user to grip the self-cleaning assembly 50 when disassembling and assembling the self-cleaning assembly 50, thereby improving the assembly efficiency of the self-cleaning assembly 50.

[0157] In some embodiments, as shown in Figures 25 and 26, the base 51 further includes a base front cover 513. The base front cover 513 is disposed on the front side of the housing 10 and below the connecting plate 516. The lower end of the base front cover 513 is detachably connected to the base body 511A. The upper end of the base front cover 513 is rotatably connected to the base body 511A.

[0158] The base front cover 513 is configured to open or close the front side of the cleaning chamber 56. This facilitates cleaning of the cleaning brush 542 in the cleaning chamber 56, improves the working efficiency of the cleaning brush 542, and allows maintenance of the components inside the self-cleaning assembly 50 through the base front cover 513 when a malfunction occurs in the components inside the self-cleaning assembly 50. It also facilitates installation and removal of the components inside the self-cleaning assembly 50 (such as the second reel 53, the first reel 52, and the cleaning brush 542).

[0159] For example, as the self-cleaning assembly 50 works for a long time, the ability of the cleaning brush 542 to remove debris on the filter screen 40 is reduced. When it is necessary to clean the cleaning brush 542, the cleaning brush 542 in the cleaning chamber 56 can be cleaned by opening the base front cover 513.

[0160] In some embodiments, as shown in FIG25 , the base front cover 513 includes a rotation shaft 5131. The rotation shaft 5131 is disposed at both ends of the base front cover 513 along the length of the housing 10. The base body 511A also includes a rotation shaft hole disposed on the base body 511A. The rotation shaft 5131 engages with the rotation shaft hole to achieve a rotational connection between the base front cover 513 and the base body 511A. Thus, when the base front cover 513 is opened, the lower side of the base front cover 513 flips upward to open the front side of the cleaning chamber 56.

[0161] In some embodiments, as shown in Figures 24 and 25, the cleaning brush assembly 54 further includes at least one stopper 546. The at least one stopper 546 is disposed at one end of the cleaning brush base 541 along the length of the housing 10. For example, the at least one stopper 546 includes one stopper 546 disposed at one end of the second mounting portion 5412 along the length of the housing 10. For example, the at least one stopper 546 includes two stoppers 546 disposed at each end of the second mounting portion 5412 along the length of the housing 10.

[0162] As shown in FIG27 , the cleaning brush assembly 54 further includes a stopper 547 . The stopper 547 is disposed on the inner wall of the cleaning chamber 56 .

[0163] The limiting portion 546 is configured to abut against the stopper 547 to limit the rotation angle of the cleaning brush assembly 54. When the cleaning brush assembly 54 is in operation and the limiting portion 546 abuts against the stopper 547, the cleaning brush 542 abuts against the first reel 52 and cleans debris from the filter 40 at the abutment point. The provision of the limiting portion 546 and the stopper 547 in the cleaning brush assembly 54 facilitates limiting the rotation angle of the cleaning brush assembly 54, allowing the cleaning brush 542, under the action of the cleaning brush base 541, to precisely abut against the first reel 52, thereby cleaning the filter 40 and reducing the possibility of the cleaning brush 542 shifting during abutment with the filter 40.

[0164] For example, at least one limiting portion 546 includes a first limiting protrusion 5461 and a second limiting protrusion 5462. The first limiting protrusion 5461 and the second limiting protrusion 5462 are disposed at ends of the second mounting portion 5412 along the length direction of the housing 10 and are symmetrically disposed along the radial direction of the second mounting portion 5412.

[0165] The limiting portion 546 is configured to rotate to a first position so that the first limiting protrusion 5461 abuts against the stop portion 547, thereby causing the cleaning brush 542 to not contact the first reel 52, and the limiting portion 546 is configured to rotate to a second position so that the second limiting protrusion 5462 abuts against the stop portion 547, thereby causing the cleaning brush 542 to abut against the first reel 52.

[0166] For example, when the cleaning brush assembly 54 rotates in the clockwise direction and the limiting portion 546 rotates to the first position, the first limiting protrusion 5461 abuts against the stop portion 547, and the stop portion 547 limits the limiting portion 546 to continue rotating. The cleaning brush 542 does not contact the first reel 52, and the first limiting protrusion 5461 is located below the second limiting protrusion 5462, and the cleaning brush 542 is located below the central axis of the cleaning brush base 541.

[0167] When the cleaning brush assembly 54 rotates counterclockwise and the limiting portion 546 rotates to the second position, the second limiting protrusion 5462 abuts against the stop portion 547, and the stop portion 547 limits the limiting portion 546 to continue rotating. The cleaning brush 542 abuts against the first reel 52 and cleans the debris on the filter 40 at the abutment point.

[0168] The abutment between the second limiting protrusion 5462 and the stop portion 547 causes the cleaning brush 542 to abut against the first reel 52 , which helps to prevent the cleaning brush 542 from being misaligned with the filter 40 due to inertia, thereby reducing the cleaning effect of the cleaning brush 542 .

[0169] In some embodiments, as shown in FIG27 , the stopper 547 includes a first stopper surface 5471 and a second stopper surface 5472. When the stopper 546 is rotated to the first position, the first stopper protrusion 5461 abuts the first stopper surface 5471, and the cleaning brush 542 is not in contact with the first reel 52. When the stopper 546 is rotated to the second position, the second stopper protrusion 5462 abuts the second stopper surface 5472, and the cleaning brush 542 abuts the first reel 52 to remove debris from the filter 40.

[0170] One end of the first stop surface 5471 is connected to one end of the second stop surface 5472, and the first stop surface 5471 is located below the second stop surface 5472. The other end of the first stop surface 5471 extends along the thickness direction of the housing 10 toward the direction close to the back plate 13 and extends at an angle downward. The other end of the second stop surface 5472 extends along the thickness direction of the housing 10 toward the direction close to the back plate 13 and extends at an angle upward.

[0171] For example, when the cleaning brush base 541 rotates clockwise and the limiting portion 546 rotates to the first position, the first limiting protrusion 5461 abuts against the first stop surface 5471. The first stop surface 5471 limits the first limiting protrusion 5461 from continuing to rotate, the cleaning brush 542 does not contact the first reel 52, the first limiting protrusion 5461 is located below the second limiting protrusion 5462, and the cleaning brush 542 is located below the central axis of the cleaning brush base 541.

[0172] As the cleaning brush base 541 rotates counterclockwise and the limiting portion 546 rotates from the first position to the second position, the first limiting protrusion 5461 changes from abutting against the first stop surface 5471 to separating, and then the second limiting protrusion 5462 abuts against the second stop surface 5472, so that the cleaning brush 542 abuts against the first reel 52 to clean the filter 40.

[0173] In this way, the first stop surface 5471 and the second stop surface 5472 are set in the stop part 547, which is conducive to the abutment between the first limiting protrusion 5461 and the second limiting protrusion 5462 and the stop part 547, thereby improving the stability and reliability of the abutment between the limiting part 546 and the stop part 547 and reducing the rotation error of the cleaning brush assembly 54.

[0174] In some embodiments, as shown in Figures 23, 25, and 26, the self-cleaning assembly 50 further includes a cleaning member 59. The cleaning member 59 is disposed on a side of the base front cover 513 near the cleaning chamber 56. For example, the cleaning member 59 and the base front cover 513 can be connected by an adhesive or a snap-fit ​​structure. The cleaning member 59 is disposed on a side wall of the cleaning chamber 56 opposite to the stopper 547. When the limiter 546 rotates back and forth between the first position and the second position, the cleaning member 59 is configured to clean debris on the cleaning brush 542.

[0175] For example, the stopper 547 is disposed on the rear wall of the cleaning chamber 56, and the cleaning member 59 is disposed on the front wall of the cleaning chamber 56. When a large amount of debris is present on the filter 40 and the filter 40 needs to be cleaned, the stopper 546 rotates from the first position to the second position, and the cleaning brush 542 abuts against the first reel 52 to clean the filter 40. During this rotation, the cleaning member 59 can contact the cleaning brush 542, clearing debris from the cleaning brush 542 and keeping the cleaning brush 542 in a relatively clean state.

[0176] In this way, when the second limiting protrusion 5462 abuts against the stop portion 547 again, the cleaning brush 542 cleaned by the cleaning member 59 can better clean the debris on the filter 40, thereby improving the cleaning effect of the cleaning brush assembly 54 on the filter 40.

[0177] 23 and 25 , the base front cover 513 further includes an escape section 5132 and an extension section 5133. The structures of the escape section 5132 and the extension section 5133 are similar to those of the first cover 812 below and are not described in detail here.

[0178] In some embodiments, as shown in FIG23 , the base 51 further includes a base rear cover 515 . The base rear cover 515 is disposed between the two end covers 514 and is positioned on the rear side of the cleaning chamber 56 along the thickness direction of the housing 10 . The base rear cover 515 is opposite the base front cover 513 and is rotatably connected to the base body 511A. The base rear cover 515 includes a connecting groove disposed therein. The connecting groove is open on one side facing the cleaning brush assembly 54 . A sealing member is disposed within the connecting groove.

[0179] When the base rear cover 515 is closed to seal the rear side of the cleaning chamber 56, the sealing member is configured to seal the gap between the base rear cover 515 and the first reel 52. When the base rear cover 515 is opened to open the rear side of the cleaning chamber 56, the sealing member is spaced apart from the first reel 52. Specifically, when the base rear cover 515 is connected to the base body 511A, the base body 511A has a connecting groove on the side facing the first reel 52, and the sealing member is disposed within the connecting groove, detachably connected to the connecting groove.

[0180] The rear side of the sealing member is located in the connecting groove, and the front side of the sealing member extends out of the connecting groove and abuts against the first reel 52. For example, the sealing member is a sponge foamed with polyurethane and having high resilience.

[0181] In this way, the connecting groove is provided on the base back cover 515, and the sealing member is provided in the connecting groove, so that the first opening 563 of the cleaning chamber 56 can be abutted against the first reel 52 through the sealing member to form a seal on the first opening 563, which is beneficial to prevent the dust in the cleaning chamber 56 from flowing to the fan assembly 30 or the indoor heat exchanger 20, thereby extending the service life of the air-conditioning indoor unit 100A.

[0182] In some embodiments, as shown in FIG23 , the width of the second opening 564 is arranged to be inclined from top to bottom along the height direction of the housing 10, that is, the cross-sectional area of ​​the second opening 564 decreases from top to bottom along the height direction of the housing 10. The second opening 564 is located at the bottom of the cleaning chamber 56. The second opening 564 has a larger opening at the end closer to the cleaning chamber 56 and a smaller opening at the end closer to the dust box 55.

[0183] When the cleaning brush 542 cleans debris from the filter 40, some debris may splash onto the inner wall of the cleaning chamber 56 due to the centrifugal force generated by the rotation of the cleaning brush 542. Decreasing the diameter of the second opening 564 from top to bottom along the height direction of the housing 10 facilitates the flow of dust toward the dust box 55, avoiding dead corners on the side walls of the cleaning chamber 56 where dust could accumulate.

[0184] In some embodiments, as shown in FIG23 , the cleaning chamber 56 further includes a first extension section 561 and a second extension section 562. The first extension section 561 and the second extension section 562 are disposed at the lower portion of the cleaning chamber 56. The first extension section 561 is connected to the front wall of the cleaning chamber 56, and the second extension section 562 is connected to the rear wall of the cleaning chamber 56. A second opening 564 is defined between the first extension section 561 and the second extension section 562. The distance between the first extension section 561 and the second extension section 562 decreases from top to bottom along the height direction of the housing 10.

[0185] For example, one end of the first extension section 561 is connected to the bottom of the front wall of the cleaning chamber 56 and is located below the cleaning brush 542. The other end of the first extension section 561 extends obliquely toward the dust box 55. One end of the second extension section 562 is connected to the bottom of the rear wall of the cleaning chamber 56 and is located below the cleaning brush 542. The other end of the second extension section 562 extends obliquely toward the dust box 55.

[0186] The first extension section 561 and the second extension section 562 extend obliquely toward each other, that is, the other ends of the first extension section 561 and the second extension section 562 extend obliquely toward the center of the dust collecting box 55 at the same time, so that the first extension section 561 and the second extension section 562 are configured to form a funnel-shaped second opening 564.

[0187] In addition, the other ends of the first extension section 561 and the second extension section 562 are flush with the bottom of the cleaning chamber 56 to prevent the first extension section 561 and the second extension section 562 from interfering with the installation of the dust collecting box 55 .

[0188] Thus, the distance between the first extension section 561 and the second extension section 562 decreases from top to bottom along the height direction of the housing 10, which helps to ensure that debris removed by the cleaning brush 542 falls into the dust box 55, reducing the possibility of debris accumulating inside the cleaning chamber 56 or at the second opening 564, and reducing the risk of debris falling into areas outside the dust box 55. Furthermore, the first extension section 561 and the second extension section 562 are located entirely below the cleaning brush 542, which helps to guide debris removed from the filter 40 into the dust box 55, preventing debris from accumulating in the cleaning chamber 56.

[0189] In some embodiments, as shown in Figures 23 and 25, the self-cleaning assembly 50 further includes a plug-in portion 58. The plug-in portion 58 is provided on the connecting plate 516 and can move relative to the connecting plate 516 along the length direction of the housing 10. When the self-cleaning assembly 50 is mounted on the housing 10, the plug-in portion 58 moves along the length direction of the housing 10 to a portion of the end extending out of the base 51, and engages with the housing 10 to achieve the installation of the self-cleaning assembly 50. When the self-cleaning assembly 50 needs to be disassembled, the plug-in portion 58 is toggled so that the plug-in portion 58 moves along the length direction of the housing 10 toward the center of the base 51 to separate the plug-in portion 58 from the housing 10, thereby achieving the disassembly of the self-cleaning assembly 50 from the housing 10.

[0190] The plug-in portion 58 is provided in the self-cleaning component 50 , which facilitates the installation and removal of the self-cleaning component 50 and improves the efficiency of installing and removing the self-cleaning component 50 .

[0191] Some embodiments of the present disclosure further provide a base 81 for an air conditioner indoor unit 1000. Referring to Figures 28 and 29, the base 81 includes a base body 811, a first cover 812, and a second cover 813. The base body 811, the first cover 812, and the second cover 813 collectively define a cleaning chamber 86. The top of the cleaning chamber 86 is open to form a first opening, and the bottom of the cleaning chamber 86 is open to form a second opening.

[0192] 9 and 28 , the bracket 312 is disposed on a side of the base body 811 close to the air inlet 110 of the housing 100 and extends along the thickness direction of the housing 100 (the front-to-back direction as shown in FIG. 32 ).

[0193] 31 , in some embodiments, a first cover 812 is rotatably connected to one side (e.g., the front side) of the base body 811 and is configured to open and close at least a portion of the one side of the cleaning chamber 56. A second cover 813 is rotatably connected to the other side (e.g., the rear side) of the base body 811 opposite to the one side and is configured to open and close at least a portion of the other side of the cleaning chamber 56.

[0194] In this way, a first cover body 812 and a second cover body 813 that can rotate relative to the base body 811 are provided to facilitate the installation and disassembly of components such as the first scroll 330, the second scroll 340 and the first cleaning brush 320, so as to thoroughly clean the first cleaning brush 320 in the cleaning chamber 86 or maintain the first scroll 330 and the second scroll 340.

[0195] In some embodiments, referring to Figures 28 and 31, the base body 811 includes two end caps 814, a first connector 815, and a second connector 816. The two end caps 814 are spaced apart along the length direction of the housing 100. The first reel 330, the second reel 340, and the first cleaning brush 320 are rotatably connected between the two end caps 814. The first connector 815 and the second connector 816 both extend along the length direction of the housing 100 (the left-right direction as shown in Figure 10). The first connector 815 is connected between one side (e.g., the front side) of the two end caps 814. The second connector 816 is connected between the other side (e.g., the rear side) of the two end caps 814.

[0196] In some embodiments, the first cover 812 is rotatably connected between the front sides of the two end covers 814, and the first connector 815 is located above the first cover 812. The first cover 812 and the second connector 816 are disposed opposite each other, and a cleaning chamber 86 is defined between the first cover 812 and the second connector 816. The second cover 813 is rotatably connected between the rear sides of the two end covers 814, and the second connector 816 is located below the second cover 813. The second cover 813 and the first connector 815 are disposed opposite each other, and a first opening is defined between the second cover 813 and the first connector 815.

[0197] It is understood that the first cover 812 is part of the cleaning chamber 86 and can form a seal on the front side of the cleaning chamber 86. When the front side of the cleaning chamber 56 needs to be opened, the first cover 812 can be rotated until it abuts against the first connecting member 815. When the rear side of the cleaning chamber 56 needs to be opened, the second cover 813 can be rotated until it abuts against the second connecting member 816.

[0198] Therefore, the first connecting member 815 and the second connecting member 816 are set between the two end covers 814, and the first connecting member 815 and the second connecting member 816 connect the two end covers 814, which can increase the structural strength of the base 81 and facilitate the formation of limitations on the first cover body 812 and the second cover body 813 when the first cover body 812 and the second cover body 813 are opened.

[0199] In some embodiments, referring to Figures 28 and 31 , the first connector 815 includes a first sub-connector 8151 and a second sub-connector 8152. The first sub-connector 8151 extends along the height direction of the housing 100 (i.e., the vertical direction as shown in Figure 32 ). The end of the second sub-connector 8152 near the air inlet 110 (i.e., the upper end) is connected to the lower end of the first sub-connector 8151. Along the thickness direction of the housing 100, the end of the second sub-connector 8152 near the first cover 812 (i.e., the lower end) extends obliquely toward the first cleaning brush 320.

[0200] The arrangement of the first sub-connector 8151 and the second sub-connector 8152 ensures the structural strength of the base body 811. Since the vibration generated by the rotation of the first reel 330 may cause debris on the filter 40 to fall off, the second sub-connector 8152 is arranged to extend downward toward the first cleaning brush 320. This not only reduces the size of the self-cleaning assembly 300, but also allows debris dropped from the filter 40 to quickly fall along the second sub-connector 8152 into the cleaning chamber 86.

[0201] In some embodiments, referring to Figures 31 to 33 , one of the side of the first cover 812 that is closer to the air inlet 110 (i.e., the upper side) and the side that is farther from the air inlet 110 (i.e., the lower side) is rotatably connected to the two end caps 814. For example, the upper sides of the first cover 812 at both ends along the length of the housing 100 are rotatably connected to the two end caps 814. This allows the lower side of the first cover 812 to flip upward to open the front side of the cleaning chamber 86.

[0202] In some embodiments, the base 81 further includes at least one first positioning structure, which is disposed between the other of the side of the first cover 812 proximal to the air inlet 110 and the side distal to the air inlet 110 and at least one of the two end caps 814. The first positioning structure includes a first positioning hole 8121 and a first mating portion. The first positioning hole 8121 is formed in one of the first cover 812 and the end cap 814, and the first mating portion is disposed in the other of the first cover 812 and the end cap 814. The first mating portion is detachably connected to the first positioning hole 8121.

[0203] For example, first positioning holes 8121 are formed in the first cover 812 and are located on the lower sides of both ends of the first cover 812 along the length direction of the housing 100. A first engaging portion is provided on a side of at least one of the two end covers 814 adjacent to the cleaning chamber 86. When the first engaging portion engages with the first positioning hole 8121, the first cover 812 keeps the front side of the cleaning chamber 86 closed. When the first engaging portion is separated from the first positioning hole 8121, the first cover 812 is adapted to rotate about the upper side of the first cover 812 to open the front side of the cleaning chamber 56.

[0204] Thus, by providing a first mating portion on one of the first cover 812 and the end cover 814 and providing a first positioning hole 8121 on the other, and by engaging the first mating portion with the first positioning hole 8121, a detachable connection is achieved between the first cover 812 and the end cover 814. This simplifies the disassembly of the base 81 and facilitates opening the cleaning chamber 86 for cleaning when the first cleaning brush 320 needs to be cleaned. Furthermore, the simplicity of the first positioning structure can effectively reduce the cost of the air conditioner indoor unit 1000.

[0205] In other embodiments, the lower sides of the first cover 812 at both ends along the length of the housing 100 can be rotatably connected to the two end caps 814. In this case, the first cover 812 can be flipped downward to open the front side of the cleaning chamber 86. The first positioning holes 8121 are provided on the upper sides of both ends of the first cover 812, and the first mating portions are provided on the upper sides of the two end caps 814. The first cover 812 can be flipped upward so that the first mating portions engage with the first positioning slots to close the front side of the cleaning chamber 86.

[0206] In some embodiments, referring to FIG. 31 , the first cover 812 includes a first body 8120 and a first pivot shaft 8122. The first pivot shaft 8122 is disposed on a side (i.e., the upper side) of the first body 8120 near the air inlet 110 and extends along the length of the housing 100. First pivot holes 8142 are formed in the two end caps 814, respectively, and are disposed opposite the first pivot shaft 8122. The ends of the first pivot shaft 8122 are rotatably engaged with the first pivot holes 8142 of the two end caps 814, respectively, to enable rotation of the first cover 812.

[0207] For example, the first pivot shaft 8122 is provided on one side of the first body 8120 away from the center of the cleaning chamber 86. The lower side of the first cover 812 is rotatable around the central axis of the first pivot hole 8142 to open and close one side (e.g., the front side) of the cleaning chamber 56.

[0208] It should be noted that positioning the first pivot shaft 8122 on the upper side of the first cover 812 can increase the stability of the connection between the first cover 812 and the base body 811. Furthermore, the first cover 812 can close the front side of the cleaning chamber 86 under its own weight, thereby improving the sealing performance of the cleaning chamber 86.

[0209] In other embodiments, the first pivot shaft 8122 can also be set on the side of the two end covers 814 adjacent to the center of the cleaning chamber 56, and the first pivot hole 8142 can be set at both ends of the first cover body 812 along the length direction of the shell 100, so as to achieve the matching snap connection between the first cover body 812 and the end cover 814.

[0210] Therefore, a first pivot hole 8142 and a first pivot shaft 8122 are respectively provided on the two end covers 814 and the first cover body 812, and the rotational connection between the first cover body 812 and the two end covers 814 is realized by the fitting engagement of the first pivot shaft 8122 and the first pivot hole 8142. The structure is simple, and it is convenient to open the first cover body 812 to clean the interior of the cleaning chamber 56.

[0211] In some embodiments, referring to FIG. 31 , the first body 8120 includes a relief section 8123 and an extension section 8124. The relief section 8123 is located between the two end caps 814 and protrudes away from the central axis of the first cleaning brush 320. Along the thickness direction of the housing 100, the relief section 8123 is opposite the first cleaning brush 320. The relief section 8123 is configured to avoid the first cleaning brush 320. The first pivot shaft 8122 is disposed on a side of the relief section 8123 away from the first cleaning brush 320.

[0212] The extension section 8124 extends along the height direction of the housing 100, and the avoidance section 8123 is located above the extension section 8124. That is, the upper end of the extension section 8124 is connected to the lower end of the avoidance section 8123, and the lower end of the extension section 8124 is engaged with the dust collection box 350.

[0213] It is understood that when the first cover 812 is engaged with the base body 811, the end of the extension section 8124, which is away from the avoidance section 8123 in the height direction of the housing 10, is engaged with the upper portion of the dust box 350. In other words, when the dust box 350 is assembled with the base body 811, the upper portion of the dust box 350 is engaged with the first cover 812, thereby sealing the cleaning chamber 86 at the front and bottom sides of the base body 811.

[0214] Thus, the arrangement of the avoidance section 8123 can prevent the first cover 812 from interfering with the installation and rotation of components such as the first cleaning brush 320 inside the cleaning chamber 86. The extension section 8124 can form a seal on the front side of the cleaning chamber 86, facilitating the installation of the first cover 812 and the base body 811.

[0215] 32 and 33 , the avoidance section 8123 is formed into an arc shape that bulges away from the central axis of the first cleaning brush 320 , and the centerline of the avoidance section 8123 coincides with the central axis of the first cleaning brush 320 . That is, the avoidance section 8123 and the first cleaning brush 320 are coaxially disposed.

[0216] This, on the one hand, prevents interference between the first cover 812 and the first cleaning brush 320 when it engages with the base body 811. Furthermore, it increases the utilization of the space in the base 81, reduces the volume of the self-cleaning assembly 50, and facilitates the integrated and miniaturized design of the self-cleaning assembly 300. Furthermore, by limiting the spacing between the first cover 812 and the first cleaning brush 320, dust particles generated during the rolling of the first cleaning brush 320 can fall into the dust box 350 along the avoidance section 8123, thereby reducing dust within the cleaning chamber 86 and increasing the rate at which debris settles.

[0217] In some embodiments, referring to Figures 31 to 33 , the first pivot shaft 8122 is connected to a side of the avoidance section 8123 away from the first cleaning brush 320. The first cover 812 further includes a connecting portion 8125 disposed between the first pivot shaft 8122 and the avoidance section 8123. In other words, the first pivot shaft 8122 is connected to the avoidance section 8123 via the connecting portion 8125.

[0218] In some embodiments, referring to Figure 33, a side surface of the first pivot axis 8122 adjacent to the first scroll 330 is tangent to the first surface of the connecting portion 8125 adjacent to the first scroll 330, or a side surface of the first pivot axis 8122 adjacent to the first scroll 330 is located on the side of the first surface of the connecting portion 8125 away from the first scroll 330.

[0219] That is, the first pivot shaft 8122 and the connecting portion 8125 are located on the side of the avoidance section 8123 away from the first cleaning brush 320, and the first pivot shaft 8122 is flush with the first surface of the connecting portion 8125, and the surface of the first pivot shaft 8122 adjacent to the first reel 330 abuts the second surface of the first connecting member 815 away from the first reel 330.

[0220] In some embodiments, the upper end of the avoidance section 8123 is at least partially located on a side of the connecting portion 8125 adjacent to the first reel 52. When the first cover 812 is closed, the end surface of the second sub-connector 8152, which is adjacent to the first cleaning brush 320, abuts against a surface of the avoidance section 8123 (the surface of the upper end of the avoidance section 8123) away from the first cleaning brush 320. Furthermore, the surface of the second sub-connector 8152, which is away from the first reel 330, abuts against the first surface of the connecting portion 8125. This improves the sealing performance of the connection between the avoidance section 8123 and the first connecting portion 815, preventing dust within the cleaning chamber 86 from escaping through the connection.

[0221] 31 , the first body 8120 further includes a snap-fit ​​portion 8126 extending toward the interior of the cleaning chamber 86 . A first positioning hole 8121 is provided on a side of the snap-fit ​​portion 8126 near the cleaning chamber 86 to engage with the base body 811 .

[0222] In some embodiments, referring to Figures 31 and 33, the second cover 813 includes a second body 8130, a first extension portion 871, and a second extension portion 872. The first extension portion 871 and the second extension portion 872 are disposed at the lower end of the second body 8130. The first extension portion 871 extends obliquely downward toward the first cleaning brush 320. The second extension portion 872 is disposed on a side of the first extension portion 871 away from the first reel 330 and extends obliquely downward toward the first cleaning brush 320.

[0223] A clearance groove 8131 is defined between the first extension portion 871 and the second extension portion 872. The clearance groove 8131 is configured to clear the end (i.e., the upper end) of the second connector 816 that is adjacent to the second body 8130. The side of the clearance groove 8131 that is adjacent to the first cleaning brush 320 is open. When the second cover 813 is closed, the upper end of the second connector 816 is adapted to abut against the inner wall of the clearance groove 8131. Thus, the clearance groove 8131 can limit the second cover 813 and ensure a tight seal between the second cover 813 and the second connector 816.

[0224] In some embodiments, the second cover 813 further includes a second pivot shaft 8132. For example, the second cover 813 includes two second pivot shafts 8132. The two second pivot shafts 8132 are respectively disposed at the ends of the second extension 872 along the length direction of the housing 100. Second pivot holes 8144 are provided on the two end caps 814 at positions opposite the second pivot shafts 8132. The second pivot shafts 8132 engage with the second pivot holes 8144 to achieve a rotational connection between the second cover 813 and the two end caps 814.

[0225] 29 to 31 , a mounting groove 87 is formed on the second body 8130. The side of the mounting groove 87 facing the first reel 330 is open. The base 81 further includes a sealing member 88 disposed within the mounting groove 87. The sealing member 88 is detachably connected to the mounting groove 87.

[0226] When the second cover 813 is closed, the seal 88 is configured to seal the gap between the second cover 813 and the first reel 330. When the second cover 813 is open, the seal 88 and the first reel 330 are spaced apart. Specifically, the rear side of the seal 88 is located within the mounting groove 87, while the front side of the seal 88 extends out of the mounting groove 87 and abuts against the first reel 330. The seal 88 may be a polyurethane foam sponge.

[0227] It should be noted that the center line of the sealing member 88 and the center axis of the first reel 330 may be located in the same plane in the front-to-back direction of the housing 100 .

[0228] Thus, a mounting groove 87 is formed on the second cover 813, and a sealing member 88 is disposed within the mounting groove 87. The sealing member 88 abuts against the first reel 330 at the first opening of the cleaning chamber 86, thereby forming a seal at the first opening. This prevents dust within the cleaning chamber 86 from flowing with the air toward the fan assembly 700 or the indoor heat exchanger 600, thereby extending the service life of the air conditioner indoor unit 1000. Furthermore, the sealing member 88 is tangential to the first reel 330 to maintain contact, allowing for secondary cleaning of the filter 40 wound on the first reel 330, thereby improving the filtering effect of the filter 210 and the filtering capacity of the self-cleaning assembly 300.

[0229] 31 to 33 , the second body 8130 further includes a third extension 873, a fourth extension 874, and a fifth extension 875. The third extension 873 and the fourth extension 874 are located at opposite ends of the fifth extension 875 along the height direction of the housing 100, with the third extension 873 located above the fourth extension 874. The third extension 873 and the fourth extension 874 both extend forward, and the third extension 873, the fourth extension 874, and the fifth extension 875 collectively define a mounting slot 87.

[0230] Specifically, the second cover 813 is provided with a third extension portion 873 and a fourth extension portion 874 on a side adjacent to the first reel 330. The third extension portion 873 and the fourth extension portion 874 extend along the length of the housing 100. The seal 88 is disposed between the third extension portion 873 and the fourth extension portion 874. This simplifies the structure of the base 81 and facilitates installation of the seal 88. The third extension portion 873, the fourth extension portion 874, and the fifth extension portion 875 can be integrally formed.

[0231] In some embodiments, referring to Figures 29 and 30 , the base 81 further includes at least one second positioning structure, which is disposed between a side (i.e., the upper side) of the second cover 813 near the air inlet 110 and at least one of the two end covers 814. The second positioning structure includes a second positioning hole 8143 and a second mating portion 8133. The second positioning hole 8143 is formed in the second cover 813 and one of the two end covers 814, and the second mating portion 8133 is disposed in the other of the second cover 813 and the end cover 814. The second mating portion 8133 is detachably connected to the second positioning hole 8143.

[0232] For example, a second positioning hole 8143 is formed in each of the two end caps 814. Two second mating portions 8133 are provided on the upper portion of the second cover 813. The two second mating portions 8133 are located at both ends of the second cover 813 along the length of the housing 100. Referring to Figure 30 , the two second mating portions 8133 are located at both ends of the third extension 873 along the length of the housing 100.

[0233] It is understood that the second cover 813 is adapted to rotate about the central axis of the second pivot hole 8144 to space the sealing member 88 from the first reel 330. The shape of the second positioning hole 8143 can be rectangular or circular.

[0234] In other embodiments, the second positioning hole 8143 may also be provided at the end of the second cover 813 along the length of the housing 100, with the second mating portion 8133 provided on the side of the two end caps 814 adjacent to the cleaning chamber 56. The second cover 813 can be separated from the end caps 814 by an external force. Along the length of the housing 100, the cross-sectional area of ​​the second positioning hole 8143 is larger than the cross-sectional area of ​​the second mating portion 8133, thereby facilitating the mating engagement of the second mating portion 8133 with the second positioning hole 8143.

[0235] Therefore, a second positioning hole 8143 is set on the end cover 814, and a second matching part 8133 is set on the second cover body 813. The second cover body 813 and the end cover 814 are connected by the second positioning hole 8143 and the second matching part 8133. The detachable connection method is simple and convenient for the second cover body 813 to open the rear side of the cleaning chamber 86 to clean and replace the seal 88.

[0236] In some embodiments, referring to FIG. 28 , the second cleaning brush 370 may also be disposed on a side of the second connecting member 816 of the base body 811 close to the cleaning chamber 86 to brush away debris on the first cleaning brush 320 .

[0237] Those skilled in the art will understand that the scope of the present invention is not limited to the above specific embodiments, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application. The scope of the present application is limited by the appended claims.
