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, 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 is placed in the air duct and comes into contact with the air duct wall. In order to avoid affecting the air output effect of the air conditioner, a storage groove for the transmission component needs to be set in the air duct wall, which increases the structural complexity inside the air duct.

[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.

[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 1-14 As shown, this embodiment of the present disclosure provides an indoor unit 80 for an air conditioner, including a heat exchanger 10, a fan 20, a cleaning component 30, and a drive assembly 40.

[0055] Combination Figure 2 and Figure 3 As shown, the cleaning component 30 is disposed between the heat exchanger 10 and the fan 20. The cleaning component 30 extends in an arc shape along the circumference of the fan 20 and can contact the fan 20. The drive assembly 40 is drivenly connected to the cleaning component 30 to drive the cleaning component 30 to move along the axial direction of the fan 20.

[0056] Circumferential direction of fan 20 Figure 2 As indicated by the middle arrow. The axial direction of fan 20 is as follows. Figure 6 The direction indicated by the middle arrow.

[0057] A cleaning component 30 is disposed between the evaporator and the fan 20, and the cleaning component 30 can contact the fan 20. When the cleaning component 30 is in contact with the fan 20, it is in an active state and can clean the dust deposited on the fan 20. Combined with the rotation of the fan 20, the cleaning component 30 can achieve comprehensive circumferential cleaning of the fan 20. Combined with its own axial movement along the fan 20, the cleaning component 30 can achieve comprehensive axial cleaning of the fan 20. Through the contact between the fan 20 and the cleaning component 30 during fan rotation, dust adhering to the fan 20 can be effectively removed. The crisscrossing movement of the fan 20 and the cleaning component 30 in intersecting directions can cover a larger cleaning area, thus more effectively removing dust from the fan 20. The fan 20 can be a cross-flow fan 20.

[0058] The air conditioner indoor unit 80 provided in this embodiment has a cleaning component 30 positioned between the heat exchanger 10 and the fan 20, avoiding direct impact on airflow performance. This reduces the need for storage of the drive assembly 40, simplifying the internal structure of the air duct. Furthermore, this design makes the cleaning component 30 less visible during operation, improving the neatness and aesthetics of the air conditioner indoor unit 80. The cleaning component 30 extends in an arc along the circumference of the fan 20, allowing for better contact with the fan 20 surface and enhancing cleaning effectiveness. Driven by the drive assembly 40, the cleaning component 30 moves along the axial direction of the fan 20, covering the entire axial area of ​​the fan 20 for comprehensive cleaning. Moreover, the cleaning component 30 enables automatic cleaning of the fan 20 without disassembling the air conditioner, providing convenience, speed, and an improved user experience.

[0059] In addition, the cleaning component 30 is disposed between the heat exchanger 10 and the fan 20. The condensate on the surface of the heat exchanger 10 can capture and adsorb the dust generated during the cleaning process, reduce the dust flying in the air duct, and reduce the impact of dust on indoor air quality.

[0060] Optionally, combined Figure 3 As shown, the curvature of the cleaning component 30 is consistent with the curvature of the fan 20.

[0061] The curvature of the cleaning component 30 is consistent with that of the fan 20, which allows the cleaning component 30 to better fit the surface of the fan 20, reducing cleaning dead corners and thus improving the cleaning efficiency of the cleaning component 30.

[0062] Optionally, combined Figure 2 and Figure 3 As shown, the cleaning component 30 extends downward along the circumference of the fan 20.

[0063] When the air conditioner is a wall-mounted unit, the cross-flow fan 20 in the indoor unit 80 is typically located between the heat exchanger 10 and the air outlet. The heat exchanger 10 and the fan 20 are arranged adjacent to each other to facilitate effective heat exchange as air flows through the heat exchanger 10. The drip tray 70 is typically located below the heat exchanger 10.

[0064] The cleaning component 30 extends downward along the circumference of the fan 20, which can effectively guide the dust cleaned by the cleaning component 30 to collect downward along the cleaning component 30. Under the action of gravity, the dust can fall into the dust collection mechanism such as the water tray 70, thereby improving the dust collection effect.

[0065] Optionally, combined Figure 3 , Figure 7 , Figure 9 and Figure 14As shown, the drive assembly 40 includes a lead screw 41 and a nut 42. The lead screw 41 is located between the heat exchanger 10 and the fan 20 and 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.

[0066] 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.

[0067] Optionally, combined Figure 7 As shown, the length of the lead screw 41 is adapted to the axial length of the fan 20.

[0068] 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.

[0069] Optionally, combined Figure 5 , Figure 6 , Figure 9 and Figure 14 As shown, the indoor unit 80 of the air conditioner also includes a support frame 50, which is located between the heat exchanger 10 and the fan 20 and extends along the axial direction of the fan 20. A lead screw 41 is located on the support frame 50 and is rotatably connected to the support frame 50.

[0070] By providing a support frame 50 between the heat exchanger 10 and the fan 20, with both the support frame 50 and the lead screw 41 extending along the axial direction of the fan 20 and the lead screw 41 positioned within the support frame 50, the stability and structural strength of the lead screw 41 are enhanced. The rotatable connection between the lead screw 41 and the support frame 50 makes the lead screw 41 more stable during operation. This also makes the overall structure more compact, saving space occupied in the air duct.

[0071] Optionally, combined Figure 13 and Figure 14As shown, the indoor unit of the air conditioner also includes a pressure cover 54, the support frame 50 is provided with a first slot, the pressure cover 54 is correspondingly provided with the first slot 501, and the pressure cover 54 is connected to the support frame 50. The pressure cover is provided with a second slot 541, the second slot 541 and the first slot 501 together enclose a limiting space 55, the lead screw 41 passes through the limiting space 55, and the lead screw 41 can rotate relative to the limiting space 55.

[0072] The pressure cap 54 is connected to the support frame 50, which can securely fix the lead screw 41 in the limiting space 55. This provides a stable support point for the lead screw 41 and improves the stability of the lead screw 41.

[0073] Optionally, the pressure cap 54 is detachably connected to the support frame 50.

[0074] The gland 54 is detachably connected to the support frame 50, making the assembly and disassembly process between the lead screw 41 and the support frame 50 easier. When maintenance, repair or replacement of the lead screw 41 or the support frame 50 is required, the detachable gland 54 can be quickly removed.

[0075] Optionally, combined Figure 5 and Figure 6 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, and the two ends of the support frame 50 are connected to the side tube plate 11.

[0076] The two ends of the support frame 50 are connected to the side tube plate 11, which enables the structural stability of the support frame 50. It can be understood that the indoor unit of the air conditioner includes a casing, and the two ends of the support frame 50 can also be connected to the side panel of the casing. The two ends of the lead screw 41 can also be rotatably connected to the side tube plate 11 of the heat exchanger 10, or rotatably connected to the side panel of the casing.

[0077] Optionally, combined Figure 13 and Figure 14 As shown, the support frame 50 is provided with a slide groove 52, and the lead screw 41 is provided in the slide groove 52 and can rotate within the slide groove 52.

[0078] The lead screw 41 is mounted on the support frame 50, and the slide groove 52 provides the necessary rotation space for the lead screw 41 to avoid affecting its normal operation. At the same time, the slide groove 52 also limits the movement of the lead screw 41 to prevent it from moving excessively or falling off during operation, thus improving its stability.

[0079] Optionally, combined Figure 2-4 As shown, the cleaning component 30 is rotatably connected to the nut 42, and the cleaning component 30 can rotate 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.

[0080] like Figure 2 As shown, the cleaning component is located in the working position. Figure 4 As shown, the cleaning component is located in a non-working position. Figure 4 The direction indicated by the middle arrow is the radial direction of the fan. The cleaning component 30 can move axially along the fan 20 under the drive of the nut 42, achieving comprehensive axial cleaning of the fan 20. Simultaneously, the cleaning component 30 is rotatably connected to the nut 42, allowing it to rotate radially toward or away from the fan 20. When the cleaning component 30 rotates toward 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 toward 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.

[0081] Optionally, combined Figure 10 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.

[0082] 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.

[0083] Optionally, combined Figure 10 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.

[0084] 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.

[0085] Optionally, combined Figure 10 As shown, the support frame 50 is provided with a second stop 51, and the cleaning component 30 is provided with a second stop mating part 33. The second stop 51 and the second stop mating part 33 cooperate to limit the rotation angle of the cleaning component 30 toward the non-working position.

[0086] 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 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 excessive rotation angle of the cleaning component 30 in the non-working position, which could damage the cleaning component 30 or the evaporator.

[0087] Optionally, combined Figure 10 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.

[0088] 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.

[0089] Optionally, combined Figure 12 As shown, the support frame 50 is provided with a positioning part 53, and the nut 42 is provided with a positioning mating part 423. The positioning part 53 and the positioning mating part 423 cooperate to restrict the nut 42 from rotating relative to the support frame 50.

[0090] A lead screw 41 is mounted on the support frame 50 and is rotatably connected to it. Rotation of the lead screw 41 drives the nut 42 to move axially relative to the support frame 50 along the fan 20, thereby causing the cleaning component 30 to move axially along the fan 20. The engagement of the positioning part 53 and the positioning mating part 423 restricts the rotation of the nut 42 relative to the support frame 50, preventing the nut 42 from shifting or rotating during movement. This improves the stability of the nut 42 during transmission, ensuring the cleaning component 30 moves accurately along a predetermined path and enhancing the cleaning effect.

[0091] Optionally, combined Figure 12 As shown, the positioning part 53 includes a first limiting surface 531 and a second limiting surface 532, which are disposed in the slide groove 52. The positioning mating part 423 includes a first limiting mating surface 424 and a second limiting mating surface 425. The first limiting surface 531 and the first limiting mating surface 424 cooperate to prevent the nut 42 from rotating toward the fan 20. The second limiting surface 532 and the second limiting mating surface 425 cooperate to prevent the nut 42 from rotating toward the heat exchanger 10.

[0092] A positioning part 53 is provided on the support frame 50. The positioning part 53 includes a first limiting surface 531 and a second limiting surface 532, both of which are located in the groove 52 of the support frame 50. A positioning mating part 423 is provided on the nut 42. The positioning mating part 423 includes a first limiting mating surface 424 and a second limiting mating surface 425, which can be located on the surface of the nut 42. The first limiting surface 531 and the first limiting mating surface 424 cooperate to prevent the nut 42 from rotating toward the fan 20. The second limiting surface 532 and the second limiting mating surface 425 cooperate to prevent the nut 42 from rotating toward the heat exchanger 10. This allows the nut 42 to be fixed in two main directions of rotation, thereby effectively preventing the nut 42 from rotating relative to the support frame 50.

[0093] Optionally, the drive assembly 40 also includes a motor, which is drivenly connected to the lead screw 41 and is located on the outside of the side tube plate 11 of the heat exchanger 10.

[0094] The motor drives the lead screw 41 to rotate, which in turn moves the cleaning component 30 smoothly. Placing the motor on the outside of the side tube plate 11 avoids occupying the air duct space inside the side tube plate 11, and also facilitates the motor's heat dissipation and maintenance, while also making it easier to install and replace the motor.

[0095] Optionally, combined Figure 3 and Figure 10 As shown, the cleaning component 30 includes a brush 31.

[0096] 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 brush material is typically durable and can withstand repeated use, making it suitable as a long-term cleaning tool.

[0097] It is understandable that cleaning component 30 can also be a cleaning material such as a sponge, cloth pad, or rubber.

[0098] Optionally, combined Figure 14 As shown, the cleaning component 30 includes a first cleaning section 34 and a second cleaning section 35. The first cleaning section 34 is drivenly connected to the drive assembly 40 and extends in an arc shape along the circumference of the fan 20. The second cleaning section 35 is connected to the first cleaning section 34 and extends along the axial direction of the fan 20.

[0099] The cleaning component 30 extends in an arc shape along the circumference of the fan 20, and includes a first cleaning section 34 and a second cleaning section 35. The first cleaning section 34 extends in an arc shape along the circumference of the fan 20, forming an arc structure. The second cleaning section 35 extends axially relative to the first cleaning section 34 along the fan 20. When the cleaning component 30 moves along the axial direction of the fan 20, the second cleaning section 35 can compensate for the cleaning dead angles of the first cleaning section 34 along the axial direction of the fan 20. At the same time, the second cleaning section 35 is also arc-shaped along the circumference of the fan 20, which can effectively fit against the surface of the fan 20. The combination of the first cleaning section 34 and the second cleaning section 35 can effectively improve the cleaning effect of the cleaning component 30. When the second cleaning section 35 is located at the end of the first cleaning section 34 away from the drive assembly 40, the cleaning component 30 has a T-shaped structure or a similar T-shaped structure. The second cleaning section 35 can also be located at other positions along the circumference of the fan along the first cleaning section 34. It is understandable that the second cleaning segment 35 can also be located at one end of the first cleaning segment 34 near the drive component 40, and the second cleaning segment 35 is connected to the drive component.

[0100] Optionally, combined Figure 6 and Figure 7 As shown, the drive assembly 40 drives the cleaning component 30 to move between the first end side 211 and the second end side 212 of the fan 20 along the axial direction. When the cleaning component 30 is located at the first end side 211 and / or the second end side 212, the cleaning component 30 can be separated from the fan 20.

[0101] The drive assembly 40 drives the cleaning component 30 to move between the first end side 211 and the second end side 212 of the fan 20 along the axial direction, enabling comprehensive cleaning of the fan 20. When the cleaning component 30 is located at the first end side 211 and / or the second end side 212, the cleaning component 30 can be separated from the fan 20. When cleaning is not required, the cleaning component 30 can automatically move to the first end side 211 or the second end side 212 of the fan 20, at which point the cleaning component 30 is in a non-operating state, thus avoiding interference with the normal operation of the fan 20.

[0102] Optionally, combined Figure 6 , Figure 7 and Figure 9 As shown, there are multiple cleaning components 30, including a first cleaning component 36 and a second cleaning component 37. The first cleaning component 36 can move to the first end side 211, and the second cleaning component 37 can move to the second end side 212.

[0103] The arrangement of multiple cleaning components 30 can improve cleaning efficiency. The first cleaning component 36 can move to the first end side 211 when not in operation, and the second cleaning component 37 can move to the second end side 212 when not in operation, so as to separate the first cleaning component 36 and the second cleaning component 37 from the fan 20 and avoid affecting the normal air supply operation of the fan 20.

[0104] Optionally, combined Figure 4 , Figure 7 and Figure 8 As shown, the indoor unit of the air conditioner also includes a limiting part 60, which is provided on the first end side 211 and / or the second end side 212 of the fan 20 along the axial direction. The limiting part 60 cooperates with the cleaning member 30 so that the cleaning member 30 is limited to a non-working position separated from the fan 20.

[0105] When the cleaning component 30 is located at the first end 211 and / or the second end 212, the limiting part 60 engages with the cleaning component 30, allowing the cleaning component 30 to be confined to a non-working position separated from the fan 20. This ensures that the cleaning component 30 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 cleaning component 30 to move along the axial direction of the fan 20, releasing the limiting part 60 and allowing the cleaning component 30 to move to the working position.

[0106] Optionally, combined Figure 8 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. The cleaning member 30 can abut against the limiting stop surface 61 to restrict the cleaning member 30 from moving toward the fan 20.

[0107] 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.

[0108] Optionally, the limiting stop 61 extends along the axial direction of the fan 20.

[0109] 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.

[0110] Optionally, combined Figure 7 and Figure 8 As 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.

[0111] The fan 20 axis is the centerline of the fan 20 along its axial direction, and the fan 20 rotates around this axis. The middle part of the fan 20 refers to the middle part of the 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 the fan 20 to the first end side 211 and engage with the limiting part 60 at the first end side 211. At this time, the limiting stop surface 61 is inclined away from the fan 20 axis along the direction from the middle part of the fan 20 toward the first end side 211, 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. When the limiting part 60 is provided at the second end side 212, the cleaning member 30 can move along the axial direction of the fan 20 to the second end side 212 and engage with the limiting part 60 at the second end side 212. At this time, the limiting stop surface 61 is inclined away from the axis of the fan 20 along the middle of the fan 20 toward the second end side 212, which can guide the cleaning component 30 and guide the cleaning component 30 away from the fan 20. In this way, the cleaning component 30 can be effectively guided to a non-working position separated from the fan 20.

[0112] Optionally, combined Figure 11 As shown, the drive assembly 40 also includes a reset member 43, which is connected to the cleaning member 30 to drive the cleaning member 30 to reset from a non-working position separated from the fan 20 to a working position in contact with the fan 20.

[0113] Exemplarily, the cleaning component 30 is rotatable between a working position in contact with the fan 20 and a non-working position separated from the fan 20. In the working state, the cleaning component 30 can rotate to the working position in contact with the fan 20, and moves along the axial direction of the fan 20 between a first end side 211 and a second end side 212 of the fan 20 to clean the fan 20. In the non-working state, the cleaning component 30 moves to either the first end side 211 or the second end side 212 of the fan 20 and stops, and can rotate to the non-working position separated from the fan 20. When the fan 20 needs to be restarted, the drive assembly 40 drives the cleaning component 30 to move along the axial direction of the fan 20, while the reset component 43 drives the cleaning component 30 to rotate towards the fan 20, allowing the cleaning component 30 to reset to the working position.

[0114] 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.

[0115] Optionally, combined Figure 10 As shown, the reset component 43 is a torsion spring 431. The cleaning component 30 and the nut 42 are rotatably connected through the rotating shaft 44. The torsion spring 431 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.

[0116] The torsion spring 431 has a simple structure and can provide a stable and continuous restoring force. The elastic deformation of the torsion spring 431 stores and releases energy, enabling the automatic reset of the cleaning component 30. This allows the cleaning component 30 to maintain appropriate tension during cleaning, improving cleaning efficiency, and enabling it to quickly and accurately return to its working position when cleaning is required.

[0117] Alternatively, the pivot 44 can be a pin.

[0118] The cleaning component 30 and the nut 42 are fixedly connected by a pin. With the pin as the pivot 44, the cleaning component 30 can rotate relative to the nut 42 between a working position and a non-working position.

[0119] Optionally, combined Figure 2 As shown, the indoor unit of the air conditioner also includes a water tray 70, which is located below the heat exchanger 10 and corresponds to the cleaning component 30.

[0120] The drip tray 70 is located below the heat exchanger 10 and corresponds to the cleaning component 30, effectively collecting dust that falls during the cleaning process. Simultaneously, the drip tray 70 also effectively collects condensate generated by the heat exchanger 10 during cooling. Collecting dust through the drip tray 70 prevents dust from being released into the air during cleaning and causing secondary pollution, thereby improving airflow quality. With the cleaning component 30 extending downwards along the circumference of the fan 20, it can better guide dust into the drip tray 70 below, resulting in more efficient dust collection.

[0121] Optionally, the heat exchanger 10 is a multi-stage evaporator, which includes multiple evaporator sections, with the cleaning component 30 located between the lowest evaporator section and the fan 20.

[0122] Multi-stage evaporators offer greater flexibility in space utilization, allowing for more compact installation within the indoor unit of the air conditioner. When the air conditioner is wall-mounted, the drip tray 70 is located below the lowest evaporator stage. By placing the cleaning component 30 between the lowest evaporator stage and the fan 20, the distance between the cleaning component 30 and the drip tray 70 is reduced, thereby decreasing the risk of dust spreading in the air and improving dust collection efficiency.
