Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a cleaning mechanism for an air conditioner and an air conditioner. Background Technology

[0002] Currently, with increasing public concern about indoor air quality, healthy air conditioning has become a key demand for users. During long-term use, the fan, as a crucial air-flow component, easily accumulates dust on its blades. This affects the airflow quality and necessitates frequent fan cleaning. However, since the fan is located inside the indoor unit, it requires disassembly and removal for cleaning, making it difficult for users to clean the fan themselves.

[0003] To achieve automatic cleaning of the fan, a duct cleaning device has been disclosed in the related technology. The duct cleaning device includes a cleaning component and a transmission assembly. The cleaning component is disposed in the duct and contacts the duct wall, extending along the arc of the duct. The transmission assembly is connected to a first motor and the cleaning component, and is used to drive the cleaning component to move left and right in the duct and between the two fixed ends of the impeller to clean the duct and the impeller.

[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, the cleaning component extends along the arc of the air duct and cleans the air duct and impeller by moving left and right between the two fixed ends of the impeller. However, the cleaning efficiency is relatively low.

[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.

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0055] Combination Figures 1-15 As shown, this disclosure provides a cleaning mechanism for an air conditioner, the air conditioner including a fan 20, and the cleaning mechanism including a cleaning component 30 and a drive component 40.

[0056] Combination Figure 6 , Figure 7 and Figure 9 As shown, the cleaning component 30 includes a first cleaning component 31 and a second cleaning component 32. The first cleaning component 31 and the second cleaning component 32 are adapted to be disposed on the outside of the fan 20 and can contact the fan 20. The drive component 40 is drivenly connected to both the first cleaning component 31 and the second cleaning component 32 to drive the first cleaning component 31 and the second cleaning component 32 to move along the axial direction of the fan 20.

[0057] The axial direction of fan 20 is as follows Figure 6 As indicated by the middle arrow. The first cleaning component 31 and the second cleaning component 32 move along the axial direction of the fan 20. Simultaneously, in conjunction with the rotation of the fan 20, the first cleaning component 31 and the second cleaning component 32 form crisscrossing mutual movements with the fan 20, achieving comprehensive cleaning of the fan 20. The fan 20 can be a cross-flow fan 20.

[0058] The cleaning mechanism for an air conditioner provided in this embodiment allows both the first cleaning component 31 and the second cleaning component 32 to contact the fan 20 and clean and remove dust from it. The drive assembly 40 drives the first cleaning component 31 and the second cleaning component 32 to move along the axial direction of the fan 20, enabling them to clean the fan 20 synchronously. This allows the first cleaning component 31 and the second cleaning component 32 to clean different areas of the fan 20 simultaneously, effectively improving cleaning efficiency and reducing the time required for a single cleaning cycle.

[0059] Optionally, combined Figure 6 , Figure 7 and Figure 9 As shown, the drive assembly 40 includes a lead screw assembly 41, which extends along the axial direction of the fan 20 and is connected to both the first cleaning component 31 and the second cleaning component 32 in a transmission manner; wherein the first cleaning component 31 and the second cleaning component 32 are arranged along the axial direction of the fan 20.

[0060] The lead screw assembly 41 provides a precise transmission mechanism, accurately controlling the reciprocating motion of the first cleaning component 31 and the second cleaning component 32 along the axial direction of the fan 20. Extending axially along the fan 20, the lead screw assembly 41 ensures that the cleaning range of the first cleaning component 31 and the second cleaning component 32 covers the entire axial length of the fan 20, thereby improving cleaning coverage and ensuring that every part of the fan 20 is cleaned. During cleaning, the fan 20 rotates, the first cleaning component 31 and the second cleaning component 32 are aligned along the axial direction of the fan 20, and the lead screw assembly 41 drives the first cleaning component 31 and the second cleaning component 32 to move along the axial direction of the fan 20. This allows the first cleaning component 31 and the second cleaning component 32 to simultaneously clean corresponding positions on the same circumference of the fan 20, improving the consistency of the cleaning process and enhancing cleaning efficiency and effectiveness.

[0061] Optionally, combined Figure 7 and Figure 9As shown, the lead screw assembly 41 includes a first lead screw 42 and a second lead screw 43. The first lead screw 42 extends along the axial direction of the fan 20 and is connected to the first cleaning component 31 in a driving manner; the second lead screw 43 extends along the axial direction of the fan 20 and is connected to the second cleaning component 32 in a driving manner; wherein the first lead screw 42 and the second lead screw 43 have opposite driving directions, so as to drive the first cleaning component 31 and the second cleaning component 32 to move towards each other or away from each other along the axial direction of the fan 20.

[0062] For example, in the non-operating state, the first cleaning component 31 is located at the first end side 211 of the fan 20 along the axial direction, and the second cleaning component 32 is located at the second end side 212 of the fan 20 along the axial direction. In the operating state, under the transmission action of the first lead screw 42 and the second lead screw 43, the first cleaning component 31 and the second cleaning component 32 move simultaneously from the end side 21 of the fan 20 toward the middle of the fan 20 towards each other, and then the first cleaning component 31 and the second cleaning component 32 can also move simultaneously from the middle of the fan 20 toward the end side 21 towards each other. Through the reciprocating motion of the first cleaning component 31 and the second cleaning component 32 along the axial direction of the fan 20, combined with the rotation of the fan 20, effective cleaning of the fan 20 can be achieved. After the cleaning work is completed, the first lead screw 42 drives the first cleaning component 31 to move toward the first end side 211, and the second lead screw 43 drives the second cleaning component 32 to move toward the second end side 212. Through the opposite movement of the first cleaning component 31 and the second cleaning component 32, they move to the first end side 211 and the second end side 212 of the fan 20 along the axial direction, and then return to the non-working state.

[0063] The first lead screw 42 drives the first cleaning component 31 to move axially along the fan 20, and the second lead screw 43 drives the second cleaning component 32 to move axially along the fan 20. The first lead screw 42 and the second lead screw 43 drive in opposite directions, allowing the first cleaning component 31 and the second cleaning component 32 to move towards each other or away from each other. This allows the first cleaning component 31 and the second cleaning component 32 to move synchronously to the end side 21 of the fan 20 along the axial direction, and then to separate synchronously from the fan 20 and be stored in the end side 21.

[0064] Optionally, combined Figure 9 As shown, the threads of the first lead screw 42 and the second lead screw 43 have opposite directions of rotation.

[0065] The threads of the first lead screw 42 and the second lead screw 43 are set to opposite directions, that is, one is a right-hand thread and the other is a left-hand thread. With the threads of the first lead screw 42 and the second lead screw 43 being opposite, when the first lead screw 42 and the second lead screw 43 rotate in the same direction, the transmission directions of the first lead screw 42 and the second lead screw 43 are opposite, thereby driving the first cleaning component 31 and the second cleaning component 32 to move towards or away from each other along the axial direction of the fan 20.

[0066] It is understandable that the threads of the first lead screw 42 and the second lead screw 43 could have the same direction of rotation. By making the rotation directions of the first lead screw 42 and the second lead screw 43 opposite, the first cleaning component 31 and the second cleaning component 32 could move in opposite directions. For example, when the first lead screw 42 rotates clockwise, the second lead screw 43 rotates counterclockwise, so that the first cleaning component 31 and the second cleaning component 32 would move in opposite directions or move towards each other.

[0067] Optionally, combined Figure 13 and Figure 14 As shown, the first lead screw 42 and the second lead screw 43 are arranged along the axial direction of the fan 20. The first lead screw 42 is provided with a snap-fit ​​part 421, and the second lead screw 43 is provided with a snap-fit ​​mating part 431. The snap-fit ​​part 421 and the snap-fit ​​mating part 431 cooperate to connect the first lead screw 42 and the second lead screw 43.

[0068] The first lead screw 42 and the second lead screw 43 are arranged along the axial direction of the fan 20, making the lead screw assembly 41 more compact in spatial layout, reducing the space occupied inside the air conditioner, and also facilitating installation and maintenance. Simultaneously, the arrangement of the first lead screw 42 and the second lead screw 43 along the axial direction of the fan 20 also enables the first cleaning component 31 and the second cleaning component 32 to move collinearly along the axial direction of the fan 20, thereby improving cleaning efficiency. The locking portion 421 of the first lead screw 42 and the locking engagement portion 431 of the second lead screw 43 cooperate to ensure a stable connection between the first lead screw 42 and the second lead screw 43, thereby improving the driving stability of the first cleaning component 31 and the second cleaning component 32. Furthermore, the locking engagement of the locking portion 421 and the locking engagement portion 431 facilitates quick disassembly and assembly, improving maintenance convenience.

[0069] Optionally, combined Figure 6 , Figure 13 and Figure 15 As shown, the cleaning mechanism for the air conditioner also includes a support frame 50, which extends along the axial direction of the fan 20. The support frame 50 is provided with a limiting groove 51, and the lead screw assembly 41 is provided in the limiting groove 51 and is rotatably connected to the support frame 50.

[0070] The support frame 50 provides a stable support structure for the lead screw assembly 41, accommodating and positioning it, thereby improving transmission stability. The lead screw assembly 41 is positioned within the limiting groove 51, enhancing its stability and accuracy during movement and preventing deviation or loosening. Simultaneously, the support frame 50 also provides some protection for the lead screw assembly 41. The rotatable connection between the lead screw assembly 41 and the support frame 50 prevents the support frame 50 from affecting the transmission operation of the lead screw assembly 41, allowing it to smoothly drive the first cleaning component 31 and the second cleaning component 32 along the axial direction of the fan 20 for cleaning.

[0071] Optionally, combined Figure 13 and Figure 15 As shown, the limiting groove 51 is provided on the support frame 50 and extends along the axial direction of the fan 20. The length of the limiting groove 51 matches the length of the lead screw assembly 41.

[0072] The lead screw assembly 41 extends along the axial direction of the fan 20, and the limiting groove 51 of the support frame 50 also extends along the axial direction of the fan 20. The length of the limiting groove 51 matches the length of the lead screw assembly 41, so that the limiting groove 51 can effectively limit the lead screw assembly 41 along the entire axial direction of the fan 20.

[0073] Optionally, combined Figure 13 and Figure 15 As shown, when the lead screw assembly 41 includes a first lead screw 42 and a second lead screw 43, the ends of the first lead screw 42 and the second lead screw 43 are connected. The support frame 50 is also provided with a first slot 52. The cleaning mechanism also includes a pressure cover 60, which is correspondingly provided with the first slot 52 and is connected to the support frame 50. The pressure cover 60 is provided with a second slot 61, which together with the first slot 52 encloses a limiting space 62. The ends of the first lead screw 42 and the second lead screw 43 are embedded in the limiting space 62.

[0074] The pressure cap 60 is connected to the support frame 50, which can firmly fix the connecting ends of the first lead screw 42 and the second lead screw 43 in the limiting space 62. This provides a stable connection point for the first lead screw 42 and the second lead screw 43, reduces the vibration and displacement of the lead screw assembly 41 during operation, and improves the stability of the lead screw assembly 41. Moreover, the ends of the first lead screw 42 and the second lead screw 43 are rotatable relative to the limiting space 62, so that the lead screw assembly 41 can operate normally.

[0075] Optionally, the pressure cap 60 is detachably connected to the support frame 50.

[0076] The gland 60 is detachably connected to the support frame 50, making the assembly and disassembly process between the lead screw assembly 41 and the support frame 50 easier. When maintenance, repair or replacement of the lead screw assembly 41 or the support frame 50 is required, the detachable gland 60 can be quickly removed.

[0077] Optionally, combined Figure 15 As shown, the first cleaning component 31 includes a first cleaning section 311, which is drivenly connected to the drive assembly 40 and extends in an arc shape along the circumference of the fan 20.

[0078] Circumferential direction of fan 20 Figure 2 As indicated by the middle arrow. The first cleaning segment 311 is drivenly connected to the drive assembly 40. When the drive assembly 40 includes a first lead screw 42, the first cleaning segment 311 is drivenly connected to the first lead screw 42. By making the first cleaning segment 311 extend in an arc shape along the circumference of the fan 20, the first cleaning component 31 can better conform to the shape of the fan 20, achieving more effective cleaning. The arc design allows the first cleaning component 31 to maintain continuous contact with the fan 20 during movement, improving the continuity and thoroughness of cleaning, thereby enhancing the cleaning effect on the fan 20.

[0079] Optionally, combined Figure 15 As shown, the second cleaning component 32 includes a second cleaning section 321, which is drivenly connected to the drive assembly 40 and extends in an arc shape along the circumference of the fan 20.

[0080] The second cleaning section 321 is drivenly connected to the drive assembly 40. When the drive assembly 40 includes a second lead screw 43, the second cleaning section 321 is drivenly connected to the second lead screw 43. By making the second cleaning section 321 extend in an arc shape along the circumference of the fan 20, the second cleaning component 32 can better conform to the shape of the fan 20, achieving more effective cleaning. The arc design allows the second cleaning component 32 to maintain continuous contact with the fan 20 during movement, improving the continuity and thoroughness of cleaning, thereby enhancing the cleaning effect on the fan 20.

[0081] Optionally, combined Figure 15 As shown, the first cleaning component 31 also includes a third cleaning section 312, which is connected to the first cleaning section 311 and extends along the axial direction of the fan 20.

[0082] The first cleaning component 31 includes a first cleaning section 311 and a third cleaning section 312. The first cleaning section 311 extends in an arc shape along the circumference of the fan 20, forming an arc structure. The third cleaning section 312 extends axially relative to the first cleaning section 311 along the fan 20. When the cleaning component moves along the axial direction of the fan 20, the third cleaning section 312 can compensate for the cleaning dead angles of the first cleaning section 311 along the axial direction of the fan 20. At the same time, the third cleaning section 312 is also arc-shaped along the circumference of the fan 20, which can effectively fit with the surface of the fan 20. Through the combination of the first cleaning section 311 and the third cleaning section 312, the cleaning effect of the first cleaning component 31 can be effectively improved. When the third cleaning section 312 is located at the end of the first cleaning section 311 away from the drive assembly 40, the first cleaning component 31 has a T-shaped structure or a similar T-shaped structure. The third cleaning section 312 can also be located at other positions of the first cleaning section 311 along the circumference of the fan. It is understandable that the third cleaning segment 312 can also be located at the end of the first cleaning segment 311 near the drive component 40, and the third cleaning segment 312 is connected to the drive component.

[0083] Optionally, combined Figure 15 As shown, the second cleaning component 32 also includes a fourth cleaning section 322, which is connected to the second cleaning section 321 and extends along the axial direction of the fan 20.

[0084] The second cleaning component 32 includes a second cleaning section 321 and a fourth cleaning section 322. The second cleaning section 321 extends in an arc shape along the circumference of the fan 20, forming an arc structure. The fourth cleaning section 322 extends axially relative to the second cleaning section 321 along the fan 20. When the cleaning component moves along the axial direction of the fan 20, the fourth cleaning section 322 can compensate for the cleaning dead angles of the second cleaning section 321 along the axial direction of the fan 20. At the same time, the fourth cleaning section 322 is also arc-shaped along the circumference of the fan 20, which can effectively fit against the surface of the fan 20. Through the combination of the second cleaning section 321 and the fourth cleaning section 322, the cleaning effect of the first cleaning component 31 can be effectively improved.

[0085] When the cleaning mechanism includes a pressure cap 60, the ends of the first lead screw 42 and the second lead screw 43 are connected and located within the second slot 61 of the pressure cap 60. When the first cleaning member 31 and the second cleaning member 32 move to the position of the pressure cap 60, the first cleaning segment 311 and the second cleaning segment 321, which extend circumferentially along the fan 20, cannot clean the position of the fan 20 corresponding to the pressure cap 60. At this time, the third cleaning segment 312 and the fourth cleaning segment 322, which extend axially along the fan 20, can supplement the cleaning to the position of the fan 20 corresponding to the pressure cap 60, thereby improving the cleaning effect.

[0086] Optionally, combined Figure 2 and Figure 4As shown, the first cleaning component 31 is capable of rotating radially along the fan 20 between a working position in contact with the fan 20 and a non-working position separated from the fan 20.

[0087] Combination Figure 2 and Figure 3 As shown, when the first cleaning component 31 is in the working position, it is in contact with the fan 20, enabling it to perform cleaning operations. Combined with... Figure 4 As shown, when the first cleaning component 31 is in the non-working position, it is separated from the fan 20, thus avoiding interference with the normal operation of the fan 20. This improves the adaptability and flexibility of the cleaning mechanism, allowing the first cleaning component 31 to perform cleaning operations or remain in a non-working state as needed.

[0088] Optionally, combined Figure 7 and Figure 9 As shown, the drive assembly 40 also includes a first nut 44, which is connected to a first lead screw 42 and to a first cleaning component 31. The first lead screw 42 rotates to drive the first nut 44 to move along the axial direction of the fan 20, thereby driving the first cleaning component 31 to move along the axial direction of the fan 20. The first cleaning component 31 is rotatably connected to the first nut 44, so that the first cleaning component 31 can rotate along the radial direction of the fan 20 between a working position in contact with the fan 20 and a non-working position separated from the fan 20.

[0089] The first nut 44 reduces direct friction between the first lead screw 42 and the first cleaning component 31, extending the service life of the cleaning mechanism. Simultaneously, the first cleaning component 31 is rotatably connected to the first nut 44, allowing it to rotate towards or away from the fan 20. When rotating towards the fan 20, the first cleaning component 31 can reach a working position in contact with the fan 20, enabling it to clean the fan 20. When rotating away from the fan 20, the first cleaning component 31 can reach a non-working position, preventing interference with the normal airflow operation of the fan 20. This improves the flexibility and adaptability of the cleaning component, making the cleaning process more efficient and avoiding disruption to the normal operation of the air conditioner.

[0090] Optionally, combined Figure 10As shown, the first nut 44 is provided with a first stop portion 423, and the first cleaning component 31 is provided with a first stop mating portion 33. The first stop portion 423 and the first stop mating portion 33 cooperate to limit the rotation angle of the first cleaning component 31 toward the working position; the support frame 50 is provided with a second stop portion 53, and the first cleaning component 31 is provided with a second stop mating portion 34. The second stop portion 53 and the second stop mating portion 34 cooperate to limit the rotation angle of the first cleaning component 31 toward the non-working position.

[0091] By engaging the first stop portion 423 with the first stop mating portion 33, the rotation angle of the first cleaning component 31 toward the fan 20 can be limited, thereby defining the working position of the first cleaning component 31. This improves the positioning accuracy of the first cleaning component 31 in the working position and prevents excessive rotation angle of the first cleaning component 31 in the working position, which could affect the rotation of the fan 20. By limiting the first cleaning component 31 in the working position, damage caused by excessive rotation of the cleaning component can also be avoided. By engaging the second stop portion 53 with the second stop mating portion 34, the rotation angle of the first cleaning component 31 toward the non-working position can be limited, thereby defining the non-working position of the first cleaning component 31. This improves the positioning accuracy of the first cleaning component 31 in the non-working position and prevents excessive rotation angle of the first cleaning component 31 in the non-working position, which could damage the first cleaning component 31 or the heat exchanger 10.

[0092] Optionally, combined Figure 10 As shown, the first stop portion 423 includes a first stop surface 424, and the first stop mating portion 33 includes a first stop mating surface 331. The first stop surface 424 and the first stop mating surface 331 mate to limit the rotation angle of the first cleaning member 31 toward the working position.

[0093] The first stop surface 424 and the first stop mating surface 331 abut against each other, precisely limiting the working position of the first cleaning component 31, ensuring that the first cleaning component 31 can properly contact the fan 20 when in the working position. The abutment between the first stop surface 424 and the first stop mating surface 331 effectively limits the first cleaning component 31, preventing it from continuing to rotate after reaching the working position. This avoids the first cleaning component 31 not rotating fully towards the working position and failing to contact the fan 20, and also prevents damage caused by excessive rotation.

[0094] Optionally, combined Figure 10 As shown, the second stop portion 53 includes a second stop surface 531, and the second stop mating portion 34 includes a second stop mating surface 341. The second stop surface 531 and the second stop mating surface 341 mate to limit the rotation angle of the first cleaning member 31 toward the non-working position.

[0095] The second stop surface 531 and the second stop mating surface 341 abut against each other, precisely limiting the non-working position of the first cleaning component 31, allowing the first cleaning component 31 to better separate from the fan 20 when in the non-working position. The abutment between the second stop surface 531 and the second stop mating surface 341 effectively limits the first cleaning component 31, preventing it from continuing to rotate after reaching the non-working position. This avoids damage caused by excessive rotation of the first cleaning component 31 towards the non-working position.

[0096] Optionally, combined Figure 12 As shown, the support frame 50 is provided with a first positioning part 54, and the first nut 44 is provided with a first positioning mating part 441. The first positioning part 54 and the first positioning mating part 441 cooperate to restrict the first nut 44 from rotating relative to the support frame 50.

[0097] The first lead screw 42 is rotatably connected to the support frame 50. Rotation of the first lead screw 42 drives the first nut 44 to move axially relative to the support frame 50 along the fan 20, thereby driving the first cleaning component 31 to move axially along the fan 20. The engagement of the first positioning part 54 and the first positioning mating part 441 restricts the rotation of the first nut 44 relative to the support frame 50, preventing the first nut 44 from shifting or rotating during movement. This improves the stability of the first nut 44 during transmission, allowing the first cleaning component 31 to move accurately along a predetermined path, thus improving the cleaning effect. The first positioning part 54 includes a first groove wall 541 and a second groove wall 542 of the limiting groove 51 of the support frame 50. The first positioning mating part 441 includes a first outer surface 442 and a second outer surface 443 of the first nut 44. The first groove wall 541 abuts against the first outer surface 442, preventing the first nut 44 from rotating towards the fan 20. The second groove wall 542 abuts against the second outer surface 443, preventing the first nut 44 from rotating away from the fan 20. This effectively prevents the first nut 44 from rotating relative to the support frame 50 and the first lead screw 42.

[0098] Optionally, combined Figure 2 and Figure 4 As shown, the second cleaning component 32 is capable of rotating radially along the fan 20 between a working position in contact with the fan 20 and a non-working position separated from the fan 20.

[0099] When in the working position, the second cleaning component 32 is in contact with the fan 20, enabling cleaning operations. When not in the working position, the second cleaning component 32 is separated from the fan 20, preventing interference with the normal operation of the fan 20. This improves the adaptability and flexibility of the cleaning mechanism, allowing the second cleaning component 32 to perform cleaning operations or remain in a non-working state as needed.

[0100] Optionally, combined Figure 7 and Figure 9 As shown, the drive assembly 40 also includes a second nut 45, which is connected to the second lead screw 43 and to the second cleaning component 32. The second lead screw 43 rotates to drive the second nut 45 to move along the axial direction of the fan 20, thereby driving the second cleaning component 32 to move along the axial direction of the fan 20. The second cleaning component 32 is rotatably connected to the second nut 45, so that the second cleaning component 32 can rotate along the radial direction of the fan 20 between a working position in contact with the fan 20 and a non-working position separated from the fan 20.

[0101] The second nut 45 reduces direct friction between the second lead screw 43 and the second cleaning component 32, extending the service life of the cleaning mechanism. Simultaneously, the second cleaning component 32 is rotatably connected to the second nut 45, allowing it to rotate towards or away from the fan 20. When rotating towards the fan 20, the second cleaning component 32 can rotate to a working position in contact with the fan 20, enabling it to clean the fan 20. When rotating away from the fan 20, the second cleaning component 32 can rotate to a non-working position separated from the fan 20, preventing interference with the normal airflow operation of the fan 20. This improves the flexibility and adaptability of the cleaning component, making the cleaning process more efficient and avoiding disruption to the normal operation of the air conditioner.

[0102] Optionally, the second nut 45 is provided with a third stop portion, and the second cleaning component 32 is provided with a third stop mating portion. The third stop portion and the third stop mating portion cooperate to limit the rotation angle of the second cleaning component 32 toward the working position; the support frame 50 is provided with a fourth stop portion, and the second cleaning component 32 is provided with a fourth stop mating portion. The fourth stop portion and the fourth stop mating portion cooperate to limit the rotation angle of the second cleaning component 32 toward the non-working position.

[0103] By engaging the third stop with the third stop mating part, the rotation angle of the second cleaning component 32 toward the fan 20 can be limited, thereby defining the working position of the second cleaning component 32. This improves the positioning accuracy of the second cleaning component 32 in the working position and prevents excessive rotation angle of the second cleaning component 32 in the working position, which could affect the rotation of the fan 20. By limiting the second cleaning component 32 in the working position, damage caused by excessive rotation of the cleaning component can also be avoided. By engaging the fourth stop with the fourth stop mating part, the rotation angle of the second cleaning component 32 toward the non-working position can be limited, thereby defining the non-working position of the second cleaning component 32. This improves the positioning accuracy of the second cleaning component 32 in the non-working position and prevents excessive rotation angle of the second cleaning component 32 in the non-working position, which could damage the second cleaning component 32 or the heat exchanger 10.

[0104] Optionally, the third stop portion includes a third stop surface, and the third stop mating portion includes a third stop mating surface. The third stop surface and the third stop mating surface mate with each other to limit the rotation angle of the second cleaning member 32 toward the working position; the fourth stop portion includes a fourth stop surface, and the fourth stop mating portion includes a fourth stop mating surface. The fourth stop surface and the fourth stop mating surface mate with each other to limit the rotation angle of the second cleaning member 32 toward the non-working position.

[0105] The working position of the second cleaning component 32 can be effectively limited by the abutting and engagement of the third stop surface and the third stop mating surface. The non-working position of the second cleaning component 32 can be effectively limited by the abutting and engagement of the fourth stop surface and the fourth stop mating surface.

[0106] Optionally, the support frame 50 is provided with a second positioning part, and the second nut 45 is provided with a second positioning mating part. The second positioning part and the second positioning mating part cooperate to restrict the rotation of the second nut 45 relative to the support frame 50.

[0107] The second lead screw 43 is rotatably connected to the support frame 50. Rotation of the second lead screw 43 drives the second nut 45 to move axially relative to the support frame 50 along the fan 20, thereby driving the second cleaning component 32 to move axially along the fan 20. The cooperation between the second positioning part and the second positioning mating part restricts the rotation of the second nut 45 relative to the support frame 50, preventing the second nut 45 from shifting or rotating during movement. This improves the stability of the second nut 45 during transmission, allowing the second cleaning component 32 to move accurately along a predetermined path, thus improving the cleaning effect. The second positioning part includes a third and fourth groove wall of the limiting groove 51 of the support frame 50, and the first positioning mating part 441 includes a third and fourth outer surface of the second nut 45. The third groove wall abuts against the third outer surface, preventing the second nut 45 from rotating towards the fan 20. The fourth groove wall abuts against the fourth outer surface, preventing the second nut 45 from rotating away from the fan 20. This effectively prevents the second nut 45 from rotating relative to the support frame 50 and the second lead screw 43.

[0108] Optionally, combined Figure 7 As shown, the cleaning mechanism for the air conditioner also includes a first limiting part 80, which is disposed on the first end side 211 of the fan 20 along the axial direction. When the first cleaning member 31 moves along the axial direction of the fan 20 to the first end side 211, the first limiting part 80 cooperates with the first cleaning member 31 to limit the first cleaning member 31 to a non-working position.

[0109] When the first cleaning component 31 moves to the first end 211 of the fan 20 along the axial direction, the first limiting part engages with the first cleaning component 31, allowing the first cleaning component 31 to be confined to a non-working position separated from the fan 20. This ensures that the first cleaning component 31 can be stably maintained in the non-working position when not in operation, thereby preventing the first cleaning component 31 from interfering with the fan 20 during air conditioner operation and allowing the air conditioner to operate normally. When the fan 20 needs cleaning, the drive assembly 40 drives the first cleaning component 31 to move along the axial direction of the fan 20, which releases the first cleaning component 31 from the limiting part 80, allowing the first cleaning component 31 to move to the working position.

[0110] Optionally, combined Figure 7 and Figure 8 As shown, the cleaning mechanism for the air conditioner also includes a second limiting part 81. The second limiting part 81 is provided on the second end side 212 of the fan 20 along the axial direction. When the second cleaning member 32 moves along the axial direction of the fan 20 to the second end side 212, the second limiting part 81 cooperates with the second cleaning member 32 to limit the second cleaning member 32 to a non-working position.

[0111] When the second cleaning component 32 moves to the second end 212 along the axial direction of the fan 20, the second limiting part engages with the second cleaning component 32, allowing the second cleaning component 32 to be confined to a non-working position separated from the fan 20. This ensures that the second cleaning component 32 remains stably in the non-working position, preventing interference with the fan 20 during air conditioner operation and allowing the air conditioner to function normally. When the fan 20 requires cleaning, the drive assembly 40 drives the second cleaning component 32 to move along the axial direction of the fan 20, releasing the second cleaning component 32 from the limiting part 81 and allowing it to move to the working position.

[0112] Optionally, combined Figure 10 and Figure 11 As shown, the cleaning mechanism for the air conditioner also includes a first reset member 46, which is connected to the first cleaning member 31 to drive the first cleaning member 31 to reset from the non-working position to the working position.

[0113] When the first cleaning component 31 is in the non-working position, it is separated from the fan 20. Under the action of the first reset component 46, the first cleaning component 31 can automatically reset to the working position where it contacts the fan 20. This improves the automation level of the first cleaning component 31, reduces manual intervention, and makes the cleaning process more convenient and efficient. Simultaneously, the reset force of the first reset component 46 provides support to the first cleaning component 31 towards the fan 20, improving the contact effect between the first cleaning component 31 and the fan 20 during operation. Figure 10 andFigure 11 As shown, the first cleaning component 31 and the first nut 44 are rotatably connected via a rotating shaft 48, and the first reset component 46 is sleeved on the outside of the rotating shaft 48. The first reset component 46 can be a torsion spring. Torsion springs have a simple structure and can provide a stable and continuous reset force. By utilizing the elastic deformation of the torsion spring to store and release energy, the automatic reset of the first cleaning component 31 is achieved.

[0114] Optionally, the cleaning mechanism for the air conditioner further includes a second reset member connected to the second cleaning member 32 to drive the second cleaning member 32 to reset from the non-working position to the working position.

[0115] When the second cleaning component 32 is not in the working position, it is separated from the fan 20. Under the action of the second reset component, the second cleaning component 32 can be automatically reset to the working position in contact with the fan 20. This improves the automation level of the second cleaning component 32, reduces manual intervention, and makes the cleaning process more convenient and efficient. At the same time, the reset force of the second reset component can form a supporting force on the second cleaning component 32 towards the fan 20, improving the contact effect between the second cleaning component 32 and the fan 20 in the working state. The second reset component can be a torsion spring. The torsion spring has a simple structure and can provide a stable and continuous reset force. The elastic deformation of the torsion spring is used to store and release energy to achieve the automatic reset of the second cleaning component 32.

[0116] Optionally, combined Figure 9 As shown, the first cleaning component 31 includes a first brush 313; and / or, the second cleaning component 32 includes a second brush 323.

[0117] The brush 31 structure possesses good softness and flexibility, allowing it to better conform to the surface of the fan 20 for more thorough cleaning. The brush 31 structure can also adapt to surfaces of different shapes, including the curved portions of the fan 20 blades, effectively removing dust and dirt adhering to the fan 20. The first cleaning component 31 includes a first brush 313, or the second cleaning component 32 includes a second brush 323, which not only improves the cleaning efficiency of the first cleaning component 31 or the second cleaning component 32 but also reduces damage to the fan 20 blades. Furthermore, the material of the brush 31 is generally durable and can withstand repeated use, making it suitable as a long-term cleaning tool.

[0118] It is understood that the first cleaning component 31 and / or the second cleaning component 32 may also be cleaning materials such as sponges, cloth pads, and rubber.

[0119] Combination Figure 1 and Figures 5-7 As shown, this embodiment of the present disclosure provides an air conditioner, including a fan 20 and a cleaning mechanism for the air conditioner as described in any of the above-disclosed embodiments, wherein a first cleaning member 31 and a second cleaning member 32 are disposed outside the fan 20.

[0120] The air conditioner provided in this disclosure embodiment, because it includes the cleaning mechanism for air conditioners as described in any of the above-disclosed embodiments, possesses all the beneficial effects of the cleaning mechanism for air conditioners as described in any of the above-disclosed embodiments. By integrating the cleaning mechanism into the air conditioner, the cleaning efficiency and convenience of the air conditioner fan 20 can be significantly improved. Users no longer need to frequently disassemble the air conditioner to clean the fan 20, greatly reducing the user's maintenance burden.

[0121] Optionally, combined Figure 2 As shown, the cleaning mechanism is located between the heat exchanger 10 and the fan 20.

[0122] By placing the cleaning mechanism between the heat exchanger 10 and the fan 20, direct impact on airflow efficiency can be avoided. This reduces the need for additional storage of the drive assembly 40 at the air outlet, simplifying the internal structure of the duct. Furthermore, this design makes the first and second cleaning components 31 and 32 less visible during operation, improving the cleanliness and aesthetics of the air conditioner. Additionally, the placement of the cleaning components between the heat exchanger 10 and the fan 20 allows condensate on the surface of the heat exchanger 10 to capture and absorb dust generated during cleaning, reducing dust dispersion in the duct and minimizing its impact on indoor air quality.

[0123] Optionally, the heat exchanger 10 includes a side tube sheet 11 (such as...). Figure 5 and Figure 6 As shown, the side tube plate 11 is located on the axial end side 21 of the fan 20; the drive assembly 40 also includes a motor, which is drivenly connected to the first lead screw 42 and / or the second lead screw 43, and the motor is located on the outside of the side tube plate 11 of the heat exchanger 10.

[0124] The first lead screw 42 and / or the second lead screw 43 are driven to rotate by the power of the motor, which can drive the first cleaning component 31 and / or the second cleaning component 32 to move smoothly. The motor is set on the outside of the side tube plate 11, which can avoid occupying the air duct space on the inside of the side tube plate 11, and is also conducive to the heat dissipation and maintenance of the motor, and at the same time, it is convenient to install and replace the motor.

[0125] Optionally, combined Figure 2 and Figure 6 As shown, the air conditioner also includes a water tray 70, which is located below the heat exchanger 10 and corresponds to the first cleaning component 31 and / or the second cleaning component 32.

[0126] The drip tray 70 is located below the heat exchanger 10 and corresponds to the first cleaning component 31 and / or the second cleaning component 32, effectively collecting dust that falls during the cleaning process. Simultaneously, the drip tray 70 can also effectively collect condensate generated by the heat exchanger 10 during the cooling process. By collecting dust through the drip tray 70, secondary pollution caused by dust being blown into the air during cleaning is prevented, thereby improving airflow quality.

[0127] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments. Embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from its scope. The scope of the present disclosure is limited only by the appended claims.
