Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to an indoor unit of an air conditioner and an air conditioner. Background Technology

[0002] Currently, during the use of air conditioners, the fan and air duct easily accumulate dust. Due to the enclosed structure of the air duct and the complex layout of the fan, it is difficult for users to clean the internal dust in a timely manner through conventional methods. Usually, it is necessary to rely on professional cleaning teams to come to the site for disassembly and cleaning, which is costly.

[0003] The related technology provides an indoor unit for an air conditioner, which includes an air duct structure, a fan, a cleaning mechanism, and a dust collection mechanism. The fan is rotatably disposed within the air duct structure. The cleaning mechanism includes a dust removal component for cleaning the fan. The dust collection mechanism includes a dust collection trough located at the bottom of the air outlet side of the air duct structure and has a drainage structure. The dust removal component can move along the axial direction of the fan to clean the entire fan and collects the dust and other dirt in the dust collection trough. The dust removal component includes a brush component that is slidably disposed within the air duct near the air outlet. The brush component is connected to a slider, which moves along a worm gear, thereby driving the brush component to move.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, one end of the brush component is connected to the worm gear via a slider, while the other end of the brush component is limited by its contact with the duct wall and the volute. The contact surfaces between the brush and the duct and volute are prone to wear due to friction, leading to loosening of the limit and affecting the movement stability of the brush component.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] Combination Figure 1-8 As shown, this embodiment of the present disclosure provides an indoor unit of an air conditioner, including a housing 10, a limiting track 101, a cleaning component 30, and a rolling engagement part 403. The housing 10 is configured with an air duct 11. The limiting track 101 is disposed within the housing along the length direction of the air duct. The cleaning component 30 is disposed within the air duct 11 and contacts the inner wall surface 111 of the air duct 11. The rolling engagement part 403 is disposed on the limiting track 101, and the cleaning component 30 is connected to the rolling engagement part 403. The rolling engagement part 403 can roll along the extension direction of the limiting track 101 to drive the cleaning component 30 to move along the length direction of the air duct.

[0042] The length direction of air duct 11 is as follows Figure 6 The direction indicated by the middle arrow.

[0043] The air conditioner indoor unit provided in this embodiment features a cleaning component 30 connected to a rolling engagement part 403. The rolling engagement part 403 rolls within the limiting track 101, driving the cleaning component 30 to move. This reduces friction during the movement of the cleaning component 30, thereby improving its stability. Simultaneously, the rolling engagement part 403 and the limiting track 101 limit the movement of the cleaning component 30, allowing it to smoothly conform to the inner wall of the air duct. During its movement, the cleaning component 30 contacts the inner wall of the air duct, cleaning it. This allows the cleaning component 30 to move more precisely along the extension direction of the limiting track 101, better cleaning the dust inside the air duct 11 and improving the cleaning efficiency and effectiveness of the air conditioner indoor unit.

[0044] Optionally, combined Figure 2 As shown, the limiting track 101 is located on the outside of the air duct 11, and the limiting track 101 and the outer wall of the air duct 11 enclose a track space 102 for the rolling mating part 403 to roll.

[0045] The limiting track 101 is concealed on the outside of the air duct 11. The movement space of the rolling mating part 403 is relatively independent of the internal space of the air duct 11, and it does 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 403.

[0046] Optionally, combined Figure 3 and Figure 4 As shown, the rolling engagement part 403 includes a roller 404 and a connecting part 405. The roller 404 rolls with the limiting track 101. One end of the connecting part 405 is connected to the roller 404, and the other end of the connecting part 405 is connected to the cleaning component 30. The air duct wall 112 is provided with a guide gap 103, which connects to the track space 102, and the width of the guide gap 103 is adapted to the size of the connecting part 405.

[0047] The rolling engagement part 403 adopts the structure of roller 404 and connecting part 405. The roller 404 rolls with the limiting track 101, and the connecting part 405 connects the roller 404 and the cleaning part 30. The guide gap 103 of the air duct wall 112 connects to the track space 102 and is adapted to the size of the connecting part 405. This allows the roller 404 to roll smoothly along the limiting track 101 during the movement of the cleaning part 30. The connecting part 405 can stably transmit power between the roller 404 and the cleaning part 30, so that the cleaning part 30 can move stably along the extension direction of the limiting track 101.

[0048] The width of the guide gap 103 is adapted to the size of the connecting part 405. Specifically, the width of the guide gap 103 is slightly larger than the width of the connecting part 405, allowing the connecting part 405 to move smoothly within the guide gap 103 without causing it to wobble or become unstable during movement due to excessive clearance. This adaptation ensures that the connecting part 405 can pass smoothly through the guide gap 103, achieving a stable connection and motion transmission between the cleaning component 30 and the rolling mating part 403. 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.

[0049] Furthermore, the width of the guide gap 103 is matched with the size of the connecting part 405, which also prevents airflow in the duct 11 from flowing out through the guide gap 103. Since the width of the guide gap 103 is only slightly larger than the width of the connecting part 405, when the connecting part 405 moves within the guide gap 103, a certain sealing effect is formed between the connecting part 405 and the side wall of the guide gap 103, thereby reducing or preventing airflow leakage from the duct 11 through the guide gap 103. 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.

[0050] Optionally, the cleaning component 30 extends circumferentially along the air duct, and the curvature of the extension of the cleaning component matches the curvature of the inner wall of the air duct.

[0051] Wind duct 11 circumferential direction Figure 2 As indicated by the middle arrow, the length of air duct 11 is as follows: Figure 6 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 limiting track 101 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. Simultaneously, the curvature of the extending cleaning component matches the curvature of the inner wall surface of the air duct, allowing the cleaning component to better conform to the inner wall surface of the air duct. This achieves comprehensive, thorough cleaning of the interior of the air duct 11, thereby improving cleaning efficiency and quality.

[0052] Optionally, combined Figure 3 and Figure 4As shown, there are multiple rolling mating parts 403, including a first rolling mating part 43 and a second rolling mating part 361. The first rolling mating part 43 is disposed at the first end 34 of the cleaning component 30 along the circumference of the air duct; the second rolling mating part 361 is disposed at the second end 35 of the cleaning component 30 along the circumference of the air duct. There are multiple limiting tracks 101, including a first limiting track 44 and a second limiting track 141. The first limiting track 44 is disposed corresponding to the first rolling mating part 43; the second limiting track 141 is disposed corresponding to the second rolling mating part 361.

[0053] The first rolling engagement part 43 and the second rolling engagement part 361 are respectively disposed at both ends of the cleaning component 30 along the circumference of the air duct 11. The first limiting track 44 and the second limiting track 141 are also correspondingly disposed at both ends of the cleaning component 30 along the circumference of the air duct 11, and both the first limiting track 44 and the second limiting track 141 extend along the length direction of the air duct 11. In this way, by the engagement of the first rolling engagement part 43 with the first limiting track 44, and the engagement of the second rolling engagement part 361 with the second limiting track 141, both ends of the cleaning component 30 along the circumference of the air duct 11 can move synchronously along the length direction of the air duct 11.

[0054] The first rolling engagement part 43 and the second rolling engagement part 361 are respectively located at both ends of the cleaning component 30, and the first limiting rail 44 and the second limiting rail 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 or tilting during movement, thereby improving the stability of the cleaning component 30's movement. This allows the cleaning component 30 to maintain good contact with the inner wall of the air duct 11 throughout the entire movement, running smoothly against the inner wall of the air duct 11.

[0055] The inner wall surface of the air duct that the cleaning component described in this application contacts 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 air duct volute of the air duct 11, and the other is located at the bottom of the air duct volute of the air duct 11 near the air outlet, thus achieving a concealed arrangement of the limiting rail 101. This minimizes changes to the overall profile of the air duct 11. Simultaneously, the concealed arrangement of the limiting rail 101 improves the lubrication and service life of the rolling mating part 403.

[0056] Optionally, combined Figure 4As 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 air duct wall 112 is provided with a first guide gap 411, which connects to the first limiting track 44. The width of the first guide gap 411 is adapted to the size of the first connecting part 432.

[0057] The first roller 431 rolls in engagement 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 to form a limit at the first end 34 of the cleaning component 30. The first guide gap 411 is sized to match the first connecting part 432, so that during the movement of the cleaning component 30, the roller 404 can roll smoothly along the limiting track 101. The connecting part 405 can stably transmit power between the roller 404 and the cleaning component 30, thereby enabling the cleaning component 30 to move stably along the extension direction of the limiting track 101.

[0058] Optionally, combined Figure 4 As shown, there are at least two first rollers 431, and every two first rollers 431 are symmetrically arranged with respect to the first connecting part 432. This improves the motion stability of the first rolling mating part 43.

[0059] Optionally, combined Figure 3 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 102, and the width of the second guide gap 113 is adapted to the size of the second connecting part 363.

[0060] 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 to the track space 102 and is adapted to the size of the connecting part 405. 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 101.

[0061] Optionally, combined Figure 3As shown, there are at least two second rollers 362, and every two second rollers 362 are symmetrically arranged with respect to the second connecting part 363. This improves the motion stability of the second rolling mating part 361.

[0062] Optionally, combined Figure 4 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.

[0063] 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 403. In practical use, when the cleaning component 30 wears or is damaged due to prolonged use, 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.

[0064] Optionally, combined Figure 4 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.

[0065] 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.

[0066] Optionally, combined Figure 4 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.

[0067] 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.

[0068] Optionally, combined Figure 3 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.

[0069] 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 easier assembly and disassembly of the cleaning component 30. When cleaning or replacing the cleaning component 30, or when maintaining the rolling engagement portion 403, the snap-fit ​​structure allows for quick separation and connection, improving maintenance efficiency.

[0070] Optionally, combined Figure 3 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.

[0071] 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 403 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 and the rolling mating part 403.

[0072] 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.

[0073] For example, combined Figure 2-4 As shown, the first end 34 of the cleaning component 30 is connected to the insertion block 434 of the first rolling engagement part 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 part 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 part 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 part 361. Next, the first end 34 of the cleaning component 30 is pressed towards the first rolling engagement part 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 part 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.

[0074] 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.

[0075] Optionally, combined Figure 2 As shown, the indoor unit of the air conditioner also includes a fan 20, which is located inside the air duct 11. A cleaning component 30 is located between the fan 20 and the inner wall 111 of the air duct 11. The cleaning component 30 is provided with a sweeping part 31 and a wiping part 33. The sweeping 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.

[0076] 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 blades of the fan 20, reducing dust accumulation. 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.

[0077] 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.

[0078] 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.

[0079] Optionally, combined Figure 2 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 403.

[0080] 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.

[0081] Optionally, the cleaning unit 31 includes a brush.

[0082] The brush has excellent cleaning performance and can effectively remove dust and dirt from the fan blades. The brush bristles are soft and flexible, allowing them to reach into the gaps and corners between the fan blades and effectively remove dust and dirt adhering to the blade surface.

[0083] Optionally, the wiping part 33 includes a felt.

[0084] 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.

[0085] Optionally, combined Figure 2 and Figure 5-8 As shown, the indoor unit of the air conditioner also includes a drive module 40, which is drivenly connected to the rolling mating part 403, and the drive module 40 is correspondingly set with the limit rail 101.

[0086] By connecting the drive module 40 to the rolling mating part 403, a stable power source is provided for the movement of the cleaning component. Simultaneously, the drive module 40 is correspondingly positioned with the limiting rail 101, minimizing the space occupied inside the air duct 11 and ensuring smooth airflow without interference from the drive module 40. Furthermore, the corresponding positioning of the drive module 40 and the limiting rail 101 results in a more compact overall structure. This compact design not only reduces wasted space but also improves the overall aesthetics and installation flexibility of the air conditioner's indoor unit.

[0087] Optionally, combined Figure 2 As shown, the drive module 40 is configured to correspond to one of the first limiting rail 44 and the second limiting rail 141, and the drive module 40 is driven to one of the first rolling mating part 43 and the second rolling mating part 361.

[0088] This application takes an example where the drive module 40 is correspondingly configured with the first limiting track 44, and the drive module 40 is drivenly connected to the first rolling engagement part 43. The drive module 40 drives the first rolling engagement part 43 to roll along the first limiting track 44. The first rolling engagement part 43 drives the first end 34 of the cleaning part 30 to move along the extension direction of the first limiting track 44. The second end 35 of the cleaning part 30 moves synchronously with the first end 34, thereby driving the second rolling engagement part 361 to roll along the second limiting track 141. By connecting the drive module 40 to one of the first rolling engagement part 43 and the second rolling engagement part 361, the complexity of the drive system is simplified, the number of components and connecting lines are reduced, and production costs and maintenance difficulties are lowered.

[0089] Optionally, combined Figure 2 As shown, the housing 10 has an installation space 13 located outside the air duct 11. The drive module 40 can move relative to the housing 10 between the inside and outside of the installation space 13.

[0090] By integrating the drive module 40 into a separate module and installing it within a dedicated mounting space 13, and by allowing the drive module 40 to move between the inside and outside of the mounting space 13 relative to the housing 10, accessibility of the drive module 40 is effectively improved. This mobility allows the drive module 40 to be easily pulled out or pushed in from the mounting space 13, enabling users to access it via a pull-out mechanism without disassembling the housing 10. This simplifies the maintenance process and improves the assembly efficiency of the drive module 40.

[0091] Optionally, combined Figure 5 and Figure 8 As shown, the drive module 40 includes a housing 41 and a transmission belt 42. 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] Optionally, combined Figure 8 As shown, the first limiting track 44 is confined within the outer casing 41, the first rolling fit part 43 is correspondingly disposed within the outer casing 41, one side wall of the outer casing 41 serves as part of the air duct wall 112, and the first guide gap 411 is disposed within the outer casing 41. This allows the overall structure to be more compact.

[0096] Optionally, combined Figure 7 As shown, the drive module 40 also includes a drive component 45, which is disposed in the housing 41 and is connected to the transmission belt 42 to drive the transmission belt 42 to work.

[0097] 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 can be located inside or outside the housing 41. By placing the drive unit 45 in the housing 41, the power component and the transmission component are integrated, making the structure of the drive module 40 more compact and reasonable, and facilitating its installation and arrangement within the limited space of the air conditioner.

[0098] Optionally, combined Figure 8 As shown, the drive module 40 also includes a gear assembly 46, which is drivenly connected to the drive member 45 and is also drivenly connected to the transmission belt 42. The drive member 45 drives the gear assembly to rotate, thereby driving the transmission belt 42 to move.

[0099] Optionally, combined Figure 8 As shown, the gear assembly 46 includes a transmission gear 461, which is drivenly connected to the drive member 45, and one end of the transmission belt 42 is sleeved around the transmission gear 461.

[0100] The driving component 45 is a motor. The motor shaft is coaxially connected to the transmission gear 461. The motor drives the transmission gear 461 to rotate. The outer surface of the transmission belt 42 is provided with a structure that meshes with the transmission gear 461, so that the transmission gear 461 can drive the transmission belt 42 to move.

[0101] Optionally, combined Figure 8 As shown, the drive module 40 also includes a rotating shaft 47, and the other end of the transmission belt 42 is sleeved on the rotating shaft 47. The rotating shaft 47 is parallel to the axis of the transmission gear 461, so that the transmission belt 42 forms a closed-loop transmission structure.

[0102] 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 module 40 can drive the cleaning component 30 to move into the storage space.

[0103] This prevents the cleaning component 30 from affecting the operation of the fan 20 when the air conditioner is working normally.
