Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a cleaning component 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, a second groove is provided on the side wall of the air duct to house the cleaning component, keeping it in a non-working state. When the cleaning device is not in use, the cleaning component will not obstruct the normal operation of the air conditioner. This increases the complexity of the air duct structure.

[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.

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a cleaning component and an air conditioner for an air conditioner, which reduces the structural complexity of the air conditioner while achieving fan self-cleaning.

[0009] According to a first aspect of the present invention, a cleaning assembly for an air conditioner is provided. The air conditioner includes a fan, and the cleaning assembly includes: a cleaning member adapted to be disposed beside the fan and movable between a working position in contact with the fan along the radial direction of the fan and a non-working position separated from the fan; and a limiting portion adapted to be disposed on the end side of the fan along the axial direction, wherein the limiting portion limits the cleaning member when the cleaning member is in the non-working position.

[0010] Optionally, the limiting part includes a limiting stop surface located at the end of the limiting part away from the fan, so that the cleaning component can abut against the limiting stop surface when it is not in the working position, thereby restricting the cleaning component from moving toward the fan.

[0011] Optionally, the fan's axial end side includes a first end side and a second end side. When the limiting part is provided on the first end side, the limiting stop surface is inclined away from the fan axis in the direction from the middle of the fan toward the first end side; when the limiting part is provided on the second end side, the limiting stop surface is inclined away from the fan axis in the direction from the middle of the fan toward the second end side.

[0012] Optionally, the cleaning component extends circumferentially along the fan, and the dimension of the limiting portion along the axial direction of the fan is adapted to the dimension of the cleaning component along the axial direction of the fan.

[0013] Optionally, the cleaning assembly for the air conditioner further includes a drive assembly, which is driven to connect with the cleaning component to drive the cleaning component to move along the axial direction of the fan; wherein, when the cleaning component moves to the end side of the fan along the axial direction, the cleaning component can cooperate with the limiting part.

[0014] Optionally, the drive assembly includes: a lead screw extending along the axial direction of the fan; and a nut connected to the lead screw and connected to the cleaning component; wherein the lead screw rotates to drive the nut to move along the axial direction of the fan, thereby driving the cleaning component to move along the axial direction of the fan.

[0015] Optionally, the cleaning component is rotatably connected to the nut, and the cleaning component can rotate radially between the working and non-working positions of the fan.

[0016] Optionally, the nut is provided with a first stop portion, and the cleaning component is provided with a first stop mating portion, the first stop portion and the first stop mating portion cooperating to limit the rotation angle of the cleaning component toward the working position; and / or, the cleaning assembly further includes a support frame, the support frame extending along the axial direction of the fan, and the lead screw being rotatably connected to the support frame, the support frame being provided with a second stop portion, and the cleaning component being provided with a second stop mating portion, the second stop portion and the second stop mating portion cooperating to limit the rotation angle of the cleaning component toward the non-working position.

[0017] Optionally, the cleaning component for the air conditioner further includes a reset component connected to the cleaning component to drive the cleaning component to reset from a non-working position to a working position.

[0018] Optionally, the cleaning component and the nut are rotatably connected via a rotating shaft. The reset component includes a torsion spring, which is sleeved on the rotating shaft. One end of the torsion spring abuts against the nut, and the other end of the torsion spring abuts against the cleaning component. When the cleaning component rotates to a non-working position, the torsion spring undergoes elastic deformation.

[0021] The cleaning component and air conditioner for air conditioners provided in this disclosure can achieve the following technical effects:

[0022] By limiting the cleaning component, it is stably confined to a non-operating position separated from the fan, effectively preventing interference with the fan's normal operation and ensuring the air conditioner's proper functioning. Even without a cleaning component storage structure, the cleaning component remains stably in its non-operating position, reducing the structural complexity of the air conditioner. The limiting component is located on the axial end of the fan, minimizing its impact on the duct's internal space and airflow, thus reducing its influence on air delivery performance.

[0052] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0053] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0054] Combination Figure 1-11 As shown, this disclosure provides a cleaning component for an air conditioner, the air conditioner including a fan 20, and the cleaning component including a cleaning element 30 and a limiting part 60.

[0055] The cleaning component 30 is adapted to be disposed on the side of the fan 20, and the cleaning component 30 is capable of moving along the radial direction of the fan between a working position in contact with the fan 20 and a non-working position separated from the fan 20; the limiting part 60 is adapted to be disposed on the end side 21 of the fan 20 along the axial direction, and when the cleaning component 30 is in the non-working position, the limiting part 60 limits the cleaning component 30.

[0056] The radial direction of fan 20 is as follows Figure 8 As indicated by the middle arrow. (Combined) Figure 6 and Figure 7 As shown, in the working position, the cleaning component 30 contacts the fan 20, enabling it to clean the fan 20 and remove dust adhering to it. Figure 8 and Figure 9 As shown, in the non-operating position, the cleaning component 30 is separated from the fan 20, which avoids interfering with the normal operation of the fan 20. This improves the adaptability and flexibility of the cleaning assembly, allowing the cleaning component 30 to perform cleaning operations or remain in a non-operating state as needed. The fan 20 can be a cross-flow fan 20.

[0057] The axial direction of fan 20 is as follows Figure 2 As indicated by the middle arrow. The cleaning component 30 can move along the axial direction of the fan 20, and when the cleaning component 30 moves to the end side 21 of the fan 20 along the axial direction, it can cooperate with the limiting part 60. It can be understood that the cleaning component 30 can also extend along the axial direction of the fan 20, and the length of the cleaning component 30 can be adapted to the length of the fan 20 along the axial direction, with the limiting part 60 limiting the end of the cleaning component 30. This application takes the example of the cleaning component 30 being able to move along the axial direction of the fan 20.

[0058] To prevent the cleaning component from interfering with the normal operation of the air conditioner, compared with the method of setting a second groove on the side wall of the air duct to store the cleaning component in related technologies, the setting of limiting part to limit the cleaning component in the embodiment of this disclosure is relatively simple and reduces the structural complexity.

[0059] The cleaning assembly for an air conditioner provided in this embodiment limits the cleaning component 30 by means of a limiting part 60, ensuring that the cleaning component 30 is stably positioned in a non-working position separate from the fan. This effectively prevents the cleaning component 30 from interfering with the normal operation of the fan 20, allowing the air conditioner to operate normally. Even without a storage structure for the cleaning component 30, it can be stably maintained in a non-working position, thus reducing the structural complexity of the air conditioner. The limiting part 60 is located on the axial end of the fan 20, reducing the space occupied within the duct and obstructing airflow, thereby minimizing the impact on the air delivery effect.

[0060] Optionally, combined Figure 4 and Figure 9-11 As shown, the limiting part 60 includes a limiting stop surface 61, which is located at the end of the limiting part 60 away from the fan 20. When the cleaning member 30 is in a non-working position, it can abut against the limiting stop surface 61 to restrict the cleaning member 30 from moving toward the fan 20.

[0061] A limiting stop 61 is located at the end of the limiting part 60 opposite to the fan 20. The limiting stop 61 can abut against the cleaning component 30, separating the cleaning component 30 from the fan 20, thereby stably limiting the cleaning component 30 to a non-working position. When the cleaning component 30 abuts against the limiting stop 61, it can restrict the movement of the cleaning component 30 toward the fan 20, thereby preventing the cleaning component 30 from affecting the airflow operation of the fan 20.

[0062] Optionally, combined Figure 3 and Figure 4 As shown, the limiting stop surface 61 extends along the axial direction of the fan 20.

[0063] The limiting part 60 is located at the axial end 21 of the fan 20, and the limiting stop surface 61 extends along the axial direction of the fan 20, effectively limiting the cleaning component 30 to a non-working position separated from the fan 20. The limiting stop surface 61 is provided at the end of the limiting part 60 away from the fan 20, and extends along the axial direction of the fan 20. When the drive assembly 40 drives the cleaning component 30 to move along the axial direction of the fan 20, it can increase the contact area between the limiting stop surface 61 and the cleaning component 30, thereby improving the limiting effect.

[0064] Optionally, combined Figure 2-4As shown, the end side 21 of the fan 20 along the axial direction includes a first end side 211 and a second end side 212. When the limiting part 60 is provided on the first end side 211, the limiting stop surface 61 is inclined away from the axis of the fan 20 along the direction from the middle of the fan 20 toward the first end side 211; when the limiting part 60 is provided on the second end side 212, the limiting stop surface 61 is inclined away from the axis of the fan 20 along the direction from the middle of the fan 20 toward the second end side 212.

[0065] The axis of fan 20 is the center line of fan 20 along its axial direction, and fan 20 rotates around this axis. The middle part of fan 20 refers to the middle part of fan 20 along its axial direction. When the limiting part 60 is provided at the first end side 211, the cleaning member 30 can move along the axial direction of fan 20 to the first end side 211 and cooperate with the limiting part 60 at the first end side 211. At this time, the limiting stop surface 61 is inclined away from the axis of fan 20 along the direction from the middle part of fan 20 toward the first end side 211, which can guide the cleaning member 30 and guide it to move away from fan 20. This can effectively guide the cleaning member 30 to a non-working position separated from fan 20.

[0066] With the limiting part 60 located at the second end 212, the cleaning member 30 can move along the axial direction of the fan 20 to the second end 212 and engage with the limiting part 60 at the second end 212. At this time, the limiting stop surface 61 is inclined away from the axis of the fan 20 along the direction from the middle of the fan 20 toward the second end 212, which can guide the cleaning member 30 and guide it away from the fan 20. This can effectively guide the cleaning member 30 to a non-working position separated from the fan 20.

[0067] Optionally, combined Figure 3 As shown, there are multiple limiting parts 60, including a first limiting part 62 and a second limiting part 63. The first limiting part 62 is located on the first end side 211, and the second limiting part 63 is located on the second end side 212. There are multiple cleaning parts 30, including a first cleaning part 34 and a second cleaning part 35. The first cleaning part 34 can move to the first end side 211 and cooperate with the first limiting part 62 to limit the first cleaning part 34 to a non-working position. The second cleaning part 35 can move to the second end side 212 and cooperate with the second limiting part 63 to limit the second cleaning part 35 to a non-working position.

[0068] Multiple cleaning components 30 can simultaneously clean the fan 20, improving the cleaning effect. Both the first cleaning component 34 and the second cleaning component 35 can move along the axial direction of the fan 20, cleaning different areas of the fan 20 along the axial direction respectively. The first cleaning component 34 can move between the first end side 211 and the middle of the fan 20. After moving to the first end side 211, the first cleaning component 34 can cooperate with the first limiting part 62, separating the first cleaning component 34 from the fan 20, thus limiting the first cleaning component 34 to a non-working position. The second cleaning component 35 can move between the second end side 212 and the middle of the fan 20. After moving to the second end side 212, the second cleaning component 35 can cooperate with the second limiting part 63, separating the second cleaning component 35 from the fan 20, thus limiting the second cleaning component 35 to a non-working position.

[0069] Optionally, combined Figure 6-9 As shown, the cleaning component 30 extends circumferentially along the fan 20, and the dimension of the limiting portion 60 along the axial direction of the fan 20 is adapted to the dimension of the cleaning component 30 along the axial direction of the fan 20.

[0070] Circumferential direction of fan 20 Figure 6 As indicated by the middle arrow. The dimension of the limiting portion 60 along the axial direction of the fan 20 is adapted to the dimension of the cleaning component 30 along the axial direction of the fan 20, meaning the dimension of the limiting portion 60 along the axial direction of the fan 20 is equal to or greater than the dimension of the cleaning component 30 along the axial direction of the fan 20. The limiting portion 60 is located at the end 21 of the fan 20 along the axial direction, and the cleaning component 30 extends circumferentially along the fan 20. The adaptation of the dimension of the limiting portion 60 along the axial direction of the fan 20 to the dimension of the cleaning component 30 along the axial direction of the fan 20 allows for a more effective limiting fit between the limiting portion 60 and the cleaning component 30. This improves the stability of the cleaning component 30 in its non-working position.

[0071] Optionally, combined Figure 6-9 As shown, the cleaning component 30 extends in an arc shape along the circumference of the fan 20, and the curvature of the cleaning component 30 is consistent with the curvature of the fan 20.

[0072] The cleaning component 30 extends in an arc shape along the circumference of the fan 20, allowing it to make better contact with the surface of the fan 20. The curvature of the cleaning component 30 matches that of the fan 20, enabling it to better conform to the surface of the fan 20, reducing cleaning dead angles, and thus improving the cleaning efficiency of the cleaning component 30.

[0073] Optionally, combined Figure 3As shown, the cleaning assembly for the air conditioner also includes a drive assembly 40, which is drivenly connected to the cleaning component 30 to drive the cleaning component 30 to move along the axial direction of the fan 20; wherein, when the cleaning component 30 moves to the end side 21 of the fan 20 along the axial direction, the cleaning component 30 can cooperate with the limiting part 60.

[0074] The fan 20 has an axially oriented end side 21 including a first end side 211 and a second end side 212. The drive assembly 40 drives the cleaning member 30 to move along the axial direction of the fan 20 between the first end side 211 and the second end side 212. A limiting portion 60 may be provided on the first end side 211, allowing the cleaning member 30 to engage with the limiting portion 60 on the first end side 211. This allows the cleaning member 30 to move to the first end side 211 and be confined to a non-working position when the fan 20 does not require cleaning. The limiting portion 60 may also be provided on the second end side 212, allowing the cleaning member 30 to engage with the limiting portion 60 on the second end side 212. This allows the cleaning member 30 to move to the second end side 212 and be confined to a non-working position when the fan 20 does not require cleaning. The limiting portion 60 may also be provided on both the first end side 211 and the second end side 212 simultaneously.

[0075] When the limiting part 60 is provided on the first end side 211 and the limiting stop surface 61 is inclined away from the axis of the fan 20 along the direction from the middle of the fan 20 toward the first end side 211, when the drive assembly 40 drives the cleaning part 30 to move from the middle of the fan 20 to the first end side 211, the limiting stop surface 61 can guide the cleaning part 30 to move toward the non-working position. When the drive assembly 40 drives the cleaning part 30 to move from the first end side 211 toward the middle of the fan 20, the limiting stop surface 61 can guide the cleaning part 30 to move toward the working position.

[0076] When the limiting part 60 is provided on the second end side 212 and the limiting stop surface 61 is inclined away from the axis of the fan 20 along the direction from the middle of the fan 20 toward the second end side 212, when the drive assembly 40 drives the cleaning part 30 to move from the middle of the fan 20 to the second end side 212, the limiting stop surface 61 can guide the cleaning part 30 to move toward the non-working position. When the drive assembly 40 drives the cleaning part 30 to move from the second end side 212 toward the middle of the fan 20, the limiting stop surface 61 can guide the cleaning part 30 to move toward the working position.

[0077] During the cleaning process, the fan 20 starts to rotate. The drive assembly 40 can drive the cleaning component 30 to move along the axial direction of the fan 20. Combined with the rotation of the fan 20 itself, it can achieve comprehensive cleaning of the fan 20 in both directions. The limiting part 60 is provided on the end side 21 along the axial direction of the fan 20. When the cleaning component 30 moves to the end side 21 along the axial direction of the fan 20, the cleaning component 30 can cooperate with the limiting part 60 to limit the cleaning component 30 to a non-working position.

[0078] Optionally, combined Figure 3 , Figure 12 and Figure 13 As shown, the drive assembly 40 includes a lead screw 41 and a nut 42. The lead screw 41 extends along the axial direction of the fan 20. The nut 42 is connected to the lead screw 41 and is also connected to the cleaning component 30. The lead screw 41 rotates to drive the nut 42 to move along the axial direction of the fan 20, thereby driving the cleaning component 30 to move along the axial direction of the fan 20.

[0079] The lead screw 41 transmission system has high transmission efficiency. Extending axially along the fan 20, the lead screw 41 drives the nut 42 and the cleaning component 30 to move axially along the fan 20, achieving automated cleaning of the fan 20. The coordinated transmission of the lead screw 41 and nut 42 provides precise linear motion control, allowing the cleaning component 30 to move smoothly and accurately along the fan 20's axial direction, improving cleaning effectiveness. Furthermore, the transmission structure of the lead screw 41 and nut 42 is simple, making it easy to maintain and replace.

[0080] Optionally, combined Figure 3 As shown, the length of the lead screw 41 is adapted to the axial length of the fan 20.

[0081] The length of the lead screw 41 is matched with the axial length of the fan 20, meaning that the length of the lead screw 41 is the same as the axial length of the fan 20, or the length of the lead screw 41 is longer than the axial length of the fan 20, so that the transmission length of the lead screw 41 to the cleaning component 30 can cover the entire axial area of ​​the fan 20. This allows the cleaning component 30 to clean along the entire length of the fan 20, improving the comprehensiveness of cleaning.

[0082] Optionally, combined Figure 6-9 As shown, the cleaning component 30 is rotatably connected to the nut 42, and the cleaning component 30 can rotate between the working position and the non-working position along the radial direction of the fan 20.

[0083] The cleaning component 30 can move along the axial direction of the fan 20 under the drive of the nut 42, achieving comprehensive cleaning of the fan 20 along the axial direction. Simultaneously, the cleaning component 30 is rotatably connected to the nut 42, allowing it to rotate towards or away from the fan 20. When the cleaning component 30 rotates towards the fan 20, it can rotate to a working position in contact with the fan 20, at which point the cleaning component 30 is in working condition and can clean the fan 20. When the cleaning component 30 rotates away from the fan 20 and towards the heat exchanger 10, it can rotate to a non-working position separated from the fan 20, at which point the cleaning component 30 is in a non-working state, avoiding interference with the normal airflow operation of the fan 20. This improves the flexibility and adaptability of the cleaning component 30, making the cleaning process more efficient and avoiding disruption to the normal operation of the air conditioner.

[0084] Optionally, combined Figure 13 As shown, the nut 42 is provided with a first stop portion 421, and the cleaning component 30 is provided with a first stop mating portion 32. The first stop portion 421 and the first stop mating portion 32 cooperate to limit the rotation angle of the cleaning component 30 toward the working position.

[0085] When the cleaning component 30 rotates toward the fan 20, it can rotate to a working position that contacts the fan 20. When the cleaning component 30 is in working condition, the fan 20 is also rotating. Through the rotation of the fan 20, the cleaning component 30 can clean the entire circumferential area of ​​the fan 20. By cooperating with the first stop part 421 and the first stop mating part 32, the rotation angle of the cleaning component 30 toward the fan 20 can be limited, thereby defining the working position of the cleaning component 30. This improves the positioning accuracy of the cleaning component 30 in the working position and prevents the cleaning component 30 from rotating too much in the working position, which would affect the rotation of the fan 20. By limiting the cleaning component 30 in the working position with a stop, damage caused by excessive rotation of the cleaning component 30 can also be avoided.

[0086] Optionally, combined Figure 13 As shown, the first stop portion 421 includes a first stop surface 422, and the first stop mating portion 32 includes a first stop mating surface 321. The first stop surface 422 and the first stop mating surface 321 mate to limit the rotation angle of the cleaning component 30 toward the working position.

[0087] The first stop surface 422 and the first stop mating surface 321 abut against each other, precisely limiting the working position so that the cleaning component 30 can properly contact the fan 20 when in the working position. The abutment between the first stop surface 422 and the first stop mating surface 321 effectively limits the cleaning component 30, preventing it from continuing to rotate after reaching the working position. This avoids the cleaning component 30 not rotating fully towards the working position and thus failing to contact the fan 20, and also prevents damage caused by excessive rotation.

[0088] Optionally, combined Figure 12 and Figure 13 As shown, the cleaning assembly also includes a support frame 50, which extends along the axial direction of the fan 20, and the lead screw 41 is rotatably connected to the support frame 50. The support frame 50 is provided with a second stop portion 51, and the cleaning component 30 is provided with a second stop mating portion 33. The second stop portion 51 and the second stop mating portion 33 cooperate to limit the rotation angle of the cleaning component 30 toward the non-working position.

[0089] The support frame 50 extends axially along the fan 20, and the lead screw 41 is rotatably connected to the support frame 50, which enhances the stability and structural strength of the lead screw 41 and makes it more stable during operation. When the cleaning component 30 rotates away from the fan 20 and toward the heat exchanger 10, it can rotate to a non-working position separated from the fan 20. Through the cooperation of the second stop part 51 and the second stop mating part 33, the rotation angle of the cleaning component 30 toward the non-working position can be limited, thereby defining the non-working position of the cleaning component 30. This improves the positioning accuracy of the cleaning component 30 in the non-working position and prevents the cleaning component 30 from rotating too much in the non-working position, which could damage the cleaning component 30 or the evaporator.

[0090] Optionally, combined Figure 13 As shown, the second stop portion 51 includes a second stop surface 511, and the second stop mating portion 33 includes a second stop mating surface 331. The second stop surface 511 and the second stop mating surface 331 mate to limit the rotation angle of the cleaning member 30 toward the non-working position.

[0091] The second stop surface 511 abuts against the second stop mating surface 331, precisely limiting the non-working position and allowing the cleaning component 30 to better separate from the fan 20 when in the non-working position. The abutment between the second stop surface 511 and the second stop mating surface 331 effectively limits the cleaning component 30, preventing it from continuing to rotate after reaching the non-working position. This avoids excessive rotation of the cleaning component 30 towards the non-working position, which could cause damage.

[0092] Optionally, combined Figure 13 As shown, the cleaning assembly for the air conditioner also includes a reset member 43, which is connected to the cleaning member 30 to drive the cleaning member 30 to reset from the non-working position to the working position.

[0093] When the cleaning component 30 is not in the working position, it is separated from the fan 20. Under the action of the reset component 43, the cleaning component 30 can be automatically reset to the working position in contact with the fan 20. This can improve the automation level of the cleaning system, reduce manual intervention, and make the cleaning process more convenient and efficient. At the same time, under the reset force of the reset component 43, a supporting force can be formed on the cleaning component 30 towards the fan 20, improving the contact effect between the cleaning component 30 and the fan 20 in the working state.

[0094] Optionally, combined Figure 13 As shown, the cleaning component 30 and the nut 42 are rotatably connected by a rotating shaft 44. The reset component 43 includes a torsion spring 431, which is sleeved on the rotating shaft 44. One end of the torsion spring 431 abuts against the nut 42, and the other end of the torsion spring 431 abuts against the cleaning component 30. When the cleaning component 30 rotates to the non-working position, the torsion spring 431 undergoes elastic deformation.

[0095] The torsion spring 431 has a simple structure and can provide a stable and continuous restoring force. Utilizing the elastic deformation of the torsion spring 431 to store and release energy, the elastic deformation force of the torsion spring 431 allows the cleaning component 30 to automatically return from its non-working position to its working position when cleaning is required. This ensures that the cleaning component 30 maintains appropriate tension during cleaning, improving the cleaning effect, and allows it to quickly and accurately return to its working position when cleaning is needed. Simultaneously, the elastic force of the torsion spring 431 also provides support for the cleaning component 30 in its working position towards the fan 20, thereby improving the contact effect between the cleaning component 30 and the fan 20.

[0096] Optionally, combined Figure 6-9 As shown, the cleaning component 30 includes a brush 31.

[0097] The brush 31 possesses good softness and flexibility, allowing it to better conform to the surface of the fan 20 for a more thorough cleaning. The brush 31 can also adapt to surfaces of different shapes, including the curved sections of the fan 20 blades, effectively removing dust and dirt adhering to the fan 20. Using the brush 31 as the cleaning component 30 not only improves cleaning efficiency but also reduces damage to the fan 20 blades. Furthermore, the material of the brush 31 is typically durable and can withstand repeated use, making it suitable as a long-term cleaning tool.

[0098] It is understandable that cleaning component 30 can also be a cleaning material such as a sponge, cloth pad, or rubber.

[0099] Combination Figure 1-11 As shown, this disclosure provides an air conditioner, including a fan 20 and a cleaning component for the air conditioner as described in any of the above-disclosed embodiments, wherein a cleaning component 30 is disposed beside the fan 20; and a limiting portion 60 is disposed on the axial end side 21 of the fan 20.

[0100] The air conditioner provided in this disclosure includes the cleaning component for air conditioners described in any of the above-disclosed embodiments, and therefore has all the beneficial effects of the cleaning component for air conditioners described in any of the above-disclosed embodiments, which will not be repeated here.

[0101] Optionally, combined Figure 6-9 As shown, the air conditioner also includes a heat exchanger 10, and a cleaning component is disposed between the heat exchanger 10 and the fan 20.

[0102] 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 cleaning component 34 and the second cleaning component 35 less visible during operation, improving the cleanliness and aesthetics of the indoor unit. In addition, the cleaning component 30's placement 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.

[0103] Optionally, combined Figure 1 and Figure 2 As shown, the heat exchanger 10 includes a side tube plate 11, which 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 lead screw 41 and is located outside the side tube plate 11 of the heat exchanger 10.

[0104] The motor drives the lead screw 41 to rotate, which in turn moves the cleaning component 30 smoothly. Positioning the motor on the outside of the side tube plate 11 avoids occupying the air duct space inside the side tube plate 11, facilitates motor heat dissipation and maintenance, and also makes motor installation and replacement easier. The limiting part 60 can be located on the side tube plate 11 of the heat exchanger 10.

[0105] Optionally, combined Figure 6 and Figure 8 As shown, the air conditioner also includes a water tray 70, which is located below the cleaning unit 30 and extends along the axial direction of the fan 20.

[0106] A drip tray 70 is positioned below the cleaning component 30, corresponding to the cleaning component 30, and collects 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, thus improving airflow quality. The cleaning component 30, by moving along the axial direction of the fan 20, can thoroughly clean the fan 20. The drip tray 70 extends along the axial direction of the fan 20, corresponding to the movement direction of the cleaning component 30, enabling the drip tray 70 to effectively collect dust.
