[0042] Combination Figure 1-9 As shown, this embodiment of the present disclosure provides an indoor air conditioning unit, including a housing 10, a fan 20, a cleaning component 30, and a drive module 40. The housing 10 forms an air duct 11 and an installation space 13 inside, and the outlet of the installation space is located on one side end face of the housing. The fan is disposed in the air duct. The cleaning component 30 is movably disposed in the air duct corresponding to the fan. The drive module 40 is slidably disposed in the installation space 13. The drive module 40 is drivenly connected to the cleaning component 30 and is used to drive the cleaning component to move along the length direction of the air duct to clean the fan. The drive module can be separated from the cleaning component and pulled out from the outlet of the installation space to the outside of the housing.

[0043] Combination Figure 1 As shown, when the drive module needs maintenance or replacement, the drive module 40 can be pulled out from one side of the housing through the mounting space to the outside of the housing. Combined with... Figure 2 and Figure 3 As shown, when the indoor unit of the air conditioner is working normally, the drive module 40 is located inside the installation space 13.

[0044] The air conditioner indoor unit provided in this embodiment integrates the drive module 40 into a single independent module and installs it within a dedicated installation space 13. The outlet of the installation space is located on one side of the housing, allowing the drive module to move from the outlet relative to the installation space to the outside of the housing. Users can remove the drive module by pulling it out without disassembling the housing. This simplifies the maintenance process and improves the assembly efficiency of the drive module.

[0045] Optionally, combined Figure 3 As shown, the installation space 13 is located outside the air duct 11, independent of the internal space of the air duct.

[0046] The installation space 13 is located on the outside of the air duct 11, specifically at the lower end of the outside of the air duct 11. This makes the installation space independent of the internal space of the air duct, avoiding affecting the airflow inside the air duct 11 and maintaining the normal air supply performance of the air conditioner. This layout also facilitates the operation and maintenance of the drive module 40 on the outside of the air duct 11, further improving the convenience of maintenance and assembly of the drive module 40. In addition, the location of the installation space 13 on the outside of the air duct 11 also reduces the need for modifications to the structure of the housing 10.

[0047] Optionally, the end of the housing 10 along the length of the air duct 11 is provided with an opening that connects to the installation space 13.

[0048] The length direction of air duct 11 is as follows Figure 6 As indicated by the middle arrow, this opening allows the drive module 40 to easily enter and exit the installation space 13. The position and shape of the opening match the size of the drive module 40, improving the smoothness of installation and removal. This opening design also makes the repair and maintenance process more efficient.

[0049] Optionally, combined Figure 7 and Figure 8 As shown, the drive module 40 includes a housing 41, a transmission belt 42, and a drive component. The housing 41 is located in the installation space 13; the transmission belt 42 is located inside the housing 41 and is connected to the cleaning component 30 to drive the cleaning component 30 to move; the drive component 45 is located in the housing and is connected to the transmission belt to drive the transmission belt to work.

[0050] Using the transmission belt 42 as a transmission element offers advantages such as simple structure, smooth operation, and low noise. It stably transmits power from the drive source to the cleaning component 30, enabling the cleaning component 30 to move along a predetermined trajectory and speed, thus achieving comprehensive and uniform cleaning of the fan 20 or the inner wall of the air duct 11. Simultaneously, the housing 41 provides protection for the transmission belt 42 and drive-related components, preventing dust and debris from entering the drive module 40 and extending its service life. Integrating all drive components into the housing 10 also makes the drive module 40 more compact and easier to assemble.

[0051] Optionally, the synchronous belt drives along the length of the air duct 11 to drive the cleaning component 30 to move along the length of the air duct 11.

[0052] The synchronous belt drives along the length of the air duct 11. Correspondingly, the installation space 13 and the housing 41 both extend along the length of the air duct 11. This allows the cleaning range of the cleaning component 30 to fully cover the length of the air duct 11, thereby achieving all-round cleaning of the interior of the air duct 11 and effectively improving the cleaning effect.

[0053] Optionally, combined Figure 5 and Figure 8 As shown, the drive module 40 also includes a first rolling engagement part 43, which is located inside the housing 41. The first rolling engagement part 43 is connected to the transmission belt 42 and the cleaning component 30. The movement of the transmission belt 42 drives the first rolling engagement part 43 to move along the length of the air duct 11, thereby driving the cleaning component 30 to move.

[0054] When the transmission belt 42 moves along the length of the air duct 11, it drives the first rolling engagement part 43 to move along the length of the air duct 11, thereby driving the cleaning part 30 to move along the length of the air duct 11. The rolling engagement reduces the friction of the cleaning part 30 during its movement, thereby improving the stability of the cleaning part 30's movement.

[0055] Optionally, combined Figure 5 and Figure 8 As shown, the outer shell 41 is constructed with a first limiting track 44, which extends along the length of the air duct 11, and the first rolling engagement part 43 rolls into engagement with the first limiting track 44.

[0056] The first limiting track 44 guides and limits the movement of the first rolling mating part 43, making the driving trajectory of the drive module 40 more accurate, thereby providing precise guidance for the movement of the cleaning component 30. This allows the cleaning component 30 to move more accurately along the extension direction of the first limiting track 44, and also allows the cleaning component 30 to run smoothly against the inner wall of the air duct 11, performing cleaning more efficiently and effectively, thus improving the cleaning efficiency and effect of the indoor unit of the air conditioner.

[0057] Optionally, combined Figure 1 and Figure 6 As shown, the outer casing 41 is provided with a first guide gap 411, and the first rolling engagement part 43 is connected to the cleaning part 30 through the first guide gap 411.

[0058] The first guide gap 411 provides a connection channel between the first rolling engagement part 43 and the cleaning component 30, allowing the first rolling engagement part 43 to maintain a reliable transmission connection with the cleaning component 30 during movement, while not excessively obstructing the airflow within the air duct 11. Figure 6 As shown, one side wall of the outer casing 41 can be part of the air duct wall 112, and the first guide gap connects to the ventilation duct 11. This allows the overall structure of the indoor unit of the air conditioner to be more compact.

[0059] Optionally, combined Figure 6 As shown, both the outer casing 41 and the first guide gap 411 extend along the length of the air duct 11 to guide the cleaning component 30 to move along the length of the air duct 11.

[0060] This allows the cleaning component 30 to move smoothly and accurately along the length of the air duct 11, preventing the cleaning component 30 from shifting or shaking during movement, thereby achieving a thorough cleaning of the inside of the air duct 11.

[0061] Optionally, combined Figure 5 As shown, the first rolling engagement part 43 includes a first roller 431 and a first connecting part 432. The first roller 431 rolls with the first limiting track 44. One end of the first connecting part 432 is connected to the first roller 431, and the other end of the first connecting part 432 is connected to the first end 34 of the cleaning component 30. The width of the first guide gap 411 is adapted to the size of the first connecting part 432.

[0062] The first roller 431 rolls in cooperation with the first limiting track 44. The first connecting part 432 connects the first roller 431 and the first end 34 of the cleaning component 30. The first guide gap 411 is adapted to the size of the first connecting part 432, so that the roller can roll smoothly along the limiting track during the movement of the cleaning component 30. The power can be stably transmitted between the roller and the cleaning component 30 through the connecting part, so that the cleaning component 30 can move stably along the extension direction of the limiting track.

[0063] Optionally, combined Figure 5 As shown, there are at least two first rollers, and every two first rollers are symmetrically arranged relative to the first connecting part. This improves the motion stability of the first rolling mating part.

[0064] The width of the first guide gap 411 is adapted to the size of the first connecting part 432. Specifically, the width of the first guide gap 411 is slightly larger than the width of the first connecting part 432, allowing the first connecting part 432 to move smoothly within the first guide gap 411 without causing it to wobble or become unstable during movement due to excessive clearance. This adaptation allows the first connecting part 432 to pass smoothly through the first guide gap 411, achieving a stable connection and motion transmission between the cleaning component 30 and the first rolling mating part 43. It also allows the cleaning component 30 to move smoothly along a predetermined trajectory during movement, thereby improving the accuracy and stability of the cleaning component 30's movement.

[0065] Furthermore, the width of the first guide gap 411 is matched with the size of the first connecting part 432, which also prevents airflow in the duct 11 from flowing out through the first guide gap 411. Since the width of the first guide gap 411 is only slightly larger than the width of the first connecting part 432, when the first connecting part 432 moves within the first guide gap 411, a certain sealing effect is formed between the connecting part and the side wall of the first guide gap 411, thereby reducing or preventing airflow leakage from the duct 11 through the first guide gap 411. This allows the airflow in the duct 11 to be mainly discharged through the air outlet of the duct 11, maintaining normal airflow and ventilation effect of the indoor unit of the air conditioner.

[0066] Optionally, combined Figure 1 As shown, the outer shell 41 includes a first shell 412 and a second shell 413; the second shell 413 and the second shell 413 enclose the internal space of the outer shell 41, the first guide gap 411 is provided in the first shell 412 or the second shell 413, and the first shell 412 and the second shell 413 are detachably connected.

[0067] The outer casing 41 includes a first casing 412 and a second casing 413, which are detachably connected and enclose the internal space of the outer casing 41. This split design improves the ease of manufacturing, assembly, and maintenance of the outer casing 41. During manufacturing, the first casing 412 and the second casing 413 can be processed separately and then assembled, which not only reduces processing difficulty but also improves production efficiency. During assembly, the detachable outer casing 41 design makes it easier to install and adjust drive components located inside the outer casing 41, such as the cleaning component 30, the transmission belt 42, and the first rolling mating part 43. When it is necessary to inspect, maintain, or replace the components inside the drive module 40, simply disassembling the first casing 412 and the second casing 413 provides convenient access to the internal space of the outer casing 41, saving maintenance time and costs. One of the first housing 412 and the second housing 413 is provided on the outer wall of the corresponding air duct 11. The first guide gap 411 is provided on the outer wall of the first housing 412 or the second housing 413 corresponding to the air duct 11, so that the first rolling fit part 43 in the housing 41 can be connected to the cleaning part 30 in the air duct 11 through the first guide gap 411.

[0068] Optionally, the cleaning component 30 extends circumferentially along the air duct 11, and the first limiting track 44 extends along the length of the air duct 11.

[0069] Wind duct 11 circumferential direction Figure 3 As indicated by the middle arrow, the cleaning component 30 extends circumferentially, enabling comprehensive wiping of the circumferential surface of the inner wall of the air duct 11. The first limiting track 44 extends along the length, allowing the cleaning component 30 to move along the length of the air duct 11, thereby covering the dust accumulation area within the entire length of the air duct 11. This achieves all-round, thorough cleaning of the interior of the air duct 11, thus improving cleaning efficiency and quality.

[0070] Optionally, combined Figure 3 and Figure 5 As shown, the first end 34 of the cleaning component 30 is provided with a plug-in portion 37, and the first rolling fitting portion 43 is provided with a plug-in fitting portion 433. The plug-in portion 37 and the plug-in fitting portion 433 cooperate to make the first end 34 of the cleaning component 30 and the first rolling fitting portion 43 detachably connected.

[0071] The insertion portion 37 of the first end 34 of the cleaning component 30 engages with the insertion portion 433 of the first rolling engagement portion 43 to achieve a detachable connection. This detachable design facilitates the separate installation, replacement, and maintenance of the cleaning component 30 and the rolling engagement portion. In practical use, when the cleaning component 30 wears or is damaged due to prolonged use, it is not necessary to replace the entire cleaning assembly; only the damaged cleaning component 30 needs to be disassembled and replaced, reducing maintenance costs and difficulty. This also facilitates assembly and debugging during the manufacturing process, improving production efficiency.

[0072] Optionally, combined Figure 5 As shown, one of the plug-in part 37 and the plug-in mating part 433 is a plug block 434 and the other is a socket 371. The plug block 434 can be inserted into the socket 371 for positioning.

[0073] In this embodiment, the plug-in portion 37 can be a plug block 434, and the plug-in mating portion 433 can be a socket 371. Alternatively, the plug-in portion 37 can be a socket 371, and the plug-in mating portion 433 can be a plug block 434. This application takes the plug-in portion 37 as a socket 371 and the plug-in mating portion 433 as a plug block 434 as an example. When the cleaning component 30 needs to be installed, the plug block 434 of the first rolling mating portion 43 is aligned with the socket 371 of the first end 34 of the cleaning component 30, and then the first end 34 of the cleaning component 30 is pressed down so that the plug block 434 can be smoothly inserted into the socket 371, which can realize the quick connection and limiting of the cleaning component 30 and the first rolling mating portion 43. This connection method is simple and quick, without complicated tools or operating steps, which greatly shortens the installation time and improves the installation efficiency. Meanwhile, the engagement of the insert block 434 and the socket 371 ensures a stable connection between the cleaning component 30 and the first rolling engagement part 43 during movement, preventing problems such as poor cleaning effect or detachment of the cleaning component 30 due to loose connection. When it is necessary to disassemble the cleaning component 30 for cleaning or replacement, simply lift the first end 34 of the cleaning component 30 upwards to disengage the insert block 434 from the socket 371, thus easily removing the cleaning component 30. This detachable design not only facilitates regular cleaning and maintenance of the cleaning component 30, extending its service life, but also allows for quick replacement when the cleaning component 30 is damaged, reducing maintenance costs and downtime.

[0074] Optionally, combined Figure 5 As shown, when the first rolling mating part 43 includes the first connecting part 432, the end of the first connecting part 432 serves as the insert 434, and the first end 34 of the cleaning member 30 is provided with an insertion port 371, so that the end of the first connecting part 432 can be inserted into the insertion port 371 for positioning.

[0075] When the first rolling mating part 43 includes the first connecting part 432, the end of the first connecting part 432 can be directly inserted into the socket 371 of the first end 34 of the cleaning component 30 as a plug 434 structure. This eliminates the need to manufacture a separate plug 434 component, simplifies the component structure, and reduces the number of parts and assembly steps.

[0076] Optionally, combined Figure 3 As shown, the cleaning component 30 is in contact with the inner wall surface 111 of the air duct 11.

[0077] This enables the cleaning components 30 to effectively wipe and clean the inner wall of the air duct 11.

[0078] Optionally, combined Figure 3 and Figure 4 As shown, the housing 10 is also equipped with a second limiting track 141, and the air conditioner indoor unit also includes a second rolling engagement part 361. The second rolling engagement part 361 is located at the second end 35 of the cleaning component 30, and the second limiting track 141 is correspondingly provided with the second rolling engagement part 361.

[0079] The second rolling engagement part 361 cooperates with the second limiting track 141 to limit the second end 35 of the cleaning component 30, thereby allowing the cleaning component 30 to move stably against the inner wall surface 111 of the air duct 11. The first end 34 and the second end 35 of the cleaning component 30 are opposite ends of the cleaning component 30 along the circumference of the air duct 11, at which time the cleaning component 30 moves along the length of the air duct 11. The first rolling engagement part 43 and the second rolling engagement part 361 are respectively provided at both ends of the cleaning component 30, and the first limiting track 44 and the second limiting track 141 are respectively provided correspondingly. This multi-point support and guidance method ensures that both ends of the cleaning component 30 receive stable limiting and rolling support during movement, avoiding instability such as twisting and tilting during movement, thereby improving the stability of the movement of the cleaning component 30. At the same time, the first rolling engagement part 43 and the second rolling engagement part 361 at both ends of the cleaning component 30 work together to distribute the force on the cleaning component 30 more evenly during movement, reduce the risk of wear and deformation caused by single-point force, further extend the service life of the cleaning component, and also ensure that the cleaning component 30 maintains good contact with the inner wall of the air duct 11 throughout the entire movement process, and runs smoothly in close contact with the inner wall of the air duct 11.

[0080] The inner wall surface of the air duct that the cleaning component contacts in this application can be the wall surface of the air duct volute. The volute, as a key functional section of the air duct wall, is the core component constituting the convergence of airflow in the air duct. Both the first limiting rail 44 and the second limiting rail 141 are located on the outer side of the air duct 11. When the first limiting rail 44 and the second limiting rail 141 are arranged opposite each other along the circumference of the air duct 11, one of the first limiting rail 44 and the second limiting rail 141 is located at the top of the volute of the air duct 11, and the other is located at the bottom of the volute of the air duct 11 near the air outlet, thus achieving a concealed setting of the limiting rails. This minimizes changes to the overall profile of the air duct 11. Simultaneously, the concealed setting of the limiting rails improves the lubrication and service life of the rolling mating parts. It can be understood that when the cleaning component 30 moves circumferentially along the air duct 11, the first rolling mating part 43 and the second rolling mating part 361 are also located at both ends of the cleaning component 30 along the length direction of the air duct 11.

[0081] Optionally, combined Figure 3 and Figure 5As shown, the second limiting track 141 is located on the outside of the air duct 11, and the second limiting track 141 and the outer wall of the air duct 11 enclose a track space for the rolling mating part to roll.

[0082] The second limiting track 141 is concealed on the outside of the air duct 11. The movement space of the second rolling mating part 361 is relatively independent of the internal space of the air duct 11, and will not occupy the internal space of the air duct 11, thus avoiding affecting the airflow inside the air duct 11 and the normal operation of the impeller. At the same time, it can also prevent airflow, dust and other factors inside the air duct 11 from interfering with the movement of the rolling mating part.

[0083] Optionally, combined Figure 4 As shown, the second rolling engagement part 361 includes a second roller 362 and a second connecting part 363. The second roller 362 rolls with the second limiting track 141. One end of the second connecting part 363 is connected to the second roller 362, and the other end of the second connecting part 363 is connected to the second end 35 of the cleaning component 30. The air duct wall 112 is provided with a second guide gap 113, which communicates with the track space, and the width of the second guide gap 113 is adapted to the size of the second connecting part 363.

[0084] The second roller 362 rolls in conjunction with the second limiting track 141. The second connecting part 363 connects the second roller 362 and the second end 35 of the cleaning component 30. The second guide gap 113 of the air duct wall 112 connects the track space and is adapted to the size of the connecting part. This allows the second roller 362 to roll smoothly along the second limiting track 141 during the movement of the cleaning component 30. The second connecting part 363 can stably transmit power between the second roller 362 and the cleaning component 30, thereby enabling the cleaning component 30 to move stably along the extension direction of the limiting track.

[0085] Optionally, combined Figure 4 As shown, there are at least two second rollers, and every two second rollers are symmetrically arranged relative to the second connecting part. This improves the motion stability of the second rolling mating part.

[0086] Optionally, combined Figure 4 As shown, the second end 35 of the cleaning component 30 is provided with a snap-fit ​​portion 38, and the second rolling engagement portion 361 is provided with a snap-fit ​​engagement portion 364. The snap-fit ​​portion 38 and the snap-fit ​​engagement portion 364 cooperate to make the second end 35 of the cleaning component 30 detachably connected to the second rolling engagement portion 361.

[0087] The snap-fit ​​portion 38 of the second end 35 of the cleaning component 30 engages with the snap-fit ​​portion 364 of the second rolling engagement portion 361, allowing the second end 35 of the cleaning component 30 and the second rolling engagement portion 361 to be detachably connected via a snap-fit ​​structure, enabling more convenient assembly and disassembly of the cleaning component. When the cleaning component 30 needs to be cleaned, replaced, or the rolling engagement portion needs maintenance, the snap-fit ​​structure can quickly separate and connect the two, improving maintenance efficiency.

[0088] Optionally, combined Figure 4 As shown, the snap-fit ​​part 38 includes a snap-fit ​​groove 381 and a snap-fit ​​hole 382, ​​and the snap-fit ​​mating part 364 includes a snap-fit ​​protrusion 365. The snap-fit ​​groove 381 corresponds to the snap-fit ​​protrusion 365. After the snap-fit ​​protrusion 365 is snapped into the snap-fit ​​groove 381, it is mated with the snap-fit ​​hole 382 by a fastening member to limit the snap-fit ​​protrusion 365 to the snap-fit ​​groove 381.

[0089] The snap-fit ​​design makes the connection and disassembly between the second end 35 of the cleaning component 30 and the second rolling mating part 361 very convenient. Through the engagement of the slot 381 and the protrusion 365, and the further limiting effect of the fastening clip and the locking hole 382, ​​this structure enhances the connection stability between the cleaning component 30 and the second rolling mating part 361. When cleaning, replacing, or maintaining the rolling mating part is required, simply pulling the fastening clip out of the locking hole 382 allows the protrusion 365 to disengage from the slot 381, quickly separating the cleaning component 30 from the rolling mating part.

[0090] When the second rolling mating part 361 includes the second connecting part 363, the end of the second connecting part 363 can be directly inserted into the slot 381 of the second end 35 of the cleaning part 30 as a snap-fit ​​protrusion 365 structure. This eliminates the need to manufacture a separate snap-fit ​​protrusion 365 component, simplifies the component structure, and reduces the number of parts and assembly steps.

[0091] For example, the first end 34 of the cleaning component 30 is connected to the insertion block 434 of the first rolling engagement portion 43 via the insertion port 371, and the second end 35 of the cleaning component 30 is connected to the engagement protrusion 365 and the fastening clip of the second rolling engagement portion 361 via the slot 381. During installation, the slot 381 of the second end 35 of the cleaning component 30 is first engaged with the engagement protrusion 365 of the second rolling engagement portion 361. Then, the fastening clip is inserted into the slot 382 of the second end 35 of the cleaning component 30, thus achieving a limiting connection between the second end 35 of the cleaning component 30 and the second rolling engagement portion 361. Next, the first end 34 of the cleaning component 30 is pressed towards the first rolling engagement portion 43, causing the insertion port 371 of the first end 34 of the cleaning component 30 to engage with the insertion block 434 of the first rolling engagement portion 43. This allows for a stable connection between the first end 34 and the second end 35 of the cleaning component 30 and the corresponding first rolling mating part 43 and second rolling mating part 361, respectively. This ensures that the cleaning component 30 maintains a stable connection with the first rolling mating part 43 and second rolling mating part 361 during movement, improving the stability and reliability of the cleaning component 30's movement. This connection method not only facilitates the installation and disassembly of the cleaning component 30 but also enhances the connection strength between the cleaning component 30 and the first rolling mating part 43 and second rolling mating part 361 through a dual connection structure of snap-fit ​​and plug-in. It is understood that screws or other fasteners can also be used to fix the cleaning component 30 to the first rolling mating part 43 and second rolling mating part 361, thereby further improving the connection strength.

[0092] It is understandable that one of the snap-fit ​​part 38 and the snap-fit ​​mating part 364 could be a snap-fit ​​post and the other a snap-fit ​​opening, with the snap-fit ​​post engaging the snap-fit ​​opening to directly achieve a snap-fit ​​connection between the second end 35 of the cleaning component 30 and the second rolling mating part 361. This snap-fit ​​connection method can also achieve a detachable connection between the cleaning component 30 and the second rolling mating part 361.

[0093] Optionally, combined Figure 1 and Figure 7 As shown, the driving component 45 is located on the outer surface of one end of the housing along the length of the air duct.

[0094] The drive unit 45 can be a motor or other power device. Its stable power output can drive the transmission belt 42 to move at a predetermined speed and direction, thereby driving the cleaning unit 30 to reliably perform the cleaning task. The drive unit 45 is located on the outer surface of the housing, which reduces the size of the housing, making the structure of the drive module 40 more compact and reasonable, facilitating installation and arrangement within the limited space of the air conditioning indoor unit. Simultaneously, the drive unit 45 is located at one end of the housing along the length of the air duct, which can be placed near the outlet of the installation space, facilitating maintenance or replacement of the drive unit. It is understood that the drive unit 45 can also be located inside the housing 41.

[0095] Optionally, combined Figure 8 As shown, the drive module 40 also includes a gear assembly 46, which is driven by the drive component and driven by the transmission belt. The drive component drives the gear set to rotate, thereby driving the transmission belt 42 to move.

[0096] Optionally, combined Figure 8 As shown, the gear assembly 46 includes a transmission gear 461, which is driven by a driving component, and one end of a transmission belt is sleeved around the transmission gear.

[0097] The driving component is a motor, and the motor shaft is coaxially connected to the transmission gear. The motor drives the transmission gear to rotate. The outer surface of the transmission belt is provided with a structure that meshes with the transmission gear, so that the transmission gear can drive the transmission belt to move.

[0098] Optionally, combined Figure 8 As shown, the drive module 40 also includes a rotating shaft 47, with the other end of the transmission belt fitted onto the rotating shaft. The rotating shaft is parallel to the axis of the transmission gear, thus forming a closed-loop transmission structure.

[0099] Optionally, combined Figure 3 As shown, the indoor unit of the air conditioner also includes a fan 20, which is located in the air duct 11; wherein, the cleaning component 30 is located between the fan 20 and the inner wall 111 of the air duct 11, and the cleaning component 30 is provided with a cleaning part 31 and a wiping part 33, the cleaning part 31 is correspondingly arranged with the fan 20, and the wiping part 33 is correspondingly arranged with the inner wall of the air duct 11.

[0100] The cleaning unit 30's sweeping section 31 and wiping section 33 can simultaneously clean the fan 20 and the inner wall of the air duct 11. During operation, the fan 20 easily attracts a large amount of dust. The sweeping section 31 can specifically clean the dust on the fan 20 blades, reducing dust accumulation on the fan 20. The wiping section 33 wipes and cleans the inner wall of the air duct 11, preventing stubborn dirt from forming on the inner wall. It can also wipe away dust that falls onto the inner wall of the air duct 11 during the sweeping process. The coordinated cleaning of the fan 20 and the inner wall of the air duct 11 by the cleaning unit 30 improves the overall cleaning effect.

[0101] Optionally, the length of the air duct 11 is aligned with the axial direction of the fan 20, and the circumferential direction of the air duct 11 is aligned with the circumferential direction of the fan 20. Optionally, the fan is a cross-flow fan.

[0102] The cleaning component 30 extends circumferentially along the air duct 11, that is, along the circumferential direction of the fan 20. The cleaning component 30 can move along the length of the air duct 11, that is, the cleaning component 30 can move axially along the fan 20. In this way, the cleaning component 30 can fully cover the inner wall of the air duct 11 during movement, and at the same time, combined with the rotation of the fan 20, it can fully cover the fan blades of the fan 20, thereby achieving all-round cleaning of the fan 20 and the inner wall of the air duct 11.

[0103] Optionally, combined Figure 3 As shown, the cleaning component 30 also includes a base 32, a sweeping part 31 and a wiping part 33 are disposed opposite each other on the two sides of the base 32, and the base 32 is connected to the rolling engagement part.

[0104] The two ends of the cleaning component 30 are detachably connected to the first rolling engagement part 43 and the second rolling engagement part 361, respectively, to achieve detachable limiting and fixing. When the cleaning component 30 is disassembled, the base 32, the sweeping part 31, and the wiping part 33 can be replaced as a whole. It can be understood that the sweeping part 31 and the wiping part 33 can also be replaced individually.

[0105] Optionally, the cleaning unit 31 includes a brush.

[0106] The brush has excellent cleaning performance and can effectively remove dust and dirt from the fan blades 20. The brush bristles are soft and flexible, allowing them to reach into the gaps and corners between the fan blades 20, effectively removing dust and dirt adhering to the blade surface.

[0107] Optionally, the wiping part 33 includes a felt.

[0108] The felt has excellent adsorption properties, effectively wiping the inner wall of the air duct 11 to remove fine dust particles and stains. The fibrous structure of the felt absorbs and retains dust and dirt generated during the cleaning process, preventing them from being re-entrained. While the brush sweeps dust off the fan blades of the fan 20, the felt adsorbs dust that falls onto the inner wall of the air duct 11, improving the cleaning effect of the cleaning component 30.

[0109] Optionally, the housing 10 is also configured with a storage space located at the end of the air duct 11 along its length, and the drive assembly can drive the cleaning component 30 to move into the storage space.

[0110] This prevents the cleaning component 30 from affecting the operation of the fan 20 when the air conditioner is working normally.
