Referring to fig. 1-14, an embodiment of the present disclosure provides an air conditioner indoor unit 80 including a heat exchanger 10, a fan 20, a cleaning member 30, and a driving assembly 40.

As shown in fig. 2 and 3, the cleaning member 30 is disposed between the heat exchanger 10 and the fan 20, the cleaning member 30 extends in an arc shape along a circumferential direction of the fan 20, and the cleaning member 30 is capable of contacting the fan 20, and the driving assembly 40 is drivingly connected with the cleaning member 30 to drive the cleaning member 30 to move in an axial direction of the fan 20.

The circumference of the fan 20 is shown in the direction of the arrow in fig. 2. The axial direction of the fan 20 is shown by the arrow direction in fig. 6.

The cleaning member 30 is disposed between the evaporator and the fan 20, and the cleaning member 30 can be in contact with the fan 20. When the cleaning member 30 is in contact with the fan 20, the cleaning member 30 is in an operating state, and dust deposited by the fan 20 can be cleaned. In combination with the rotation of the fan 20, the cleaning member 30 can achieve the full cleaning of the circumference of the fan 20. In combination with the movement of the cleaning member 30 itself in the axial direction of the fan 20, the cleaning member 30 can achieve the overall cleaning of the axial direction of the fan 20. By contacting the cleaning member 30 when the fan 20 rotates, dust adhering to the fan 20 can be effectively removed. By the cross movement of both the fan 20 and the cleaning member 30 in the direction intersecting with each other in the longitudinal and transverse directions, more cleaning area can be covered, so that dust of the fan 20 can be removed more effectively. The fan 20 may be a cross-flow fan 20.

With the air conditioner indoor unit 80 provided by the embodiment of the present disclosure, the cleaning member 30 is disposed between the heat exchanger 10 and the fan 20, so that direct influence on the air outlet effect can be avoided. This reduces the number of storage devices for the drive unit 40, and thus simplifies the air duct internal structure. At the same time, this also makes the cleaning member 30 not easily seen directly during operation, thereby improving the cleanliness and beauty of the appearance of the indoor unit 80 of the air conditioner. The cleaning member 30 extends in an arc shape along the circumferential direction of the fan 20, so that the cleaning member 30 can be better contacted with the surface of the fan 20, thereby improving the cleaning effect of the fan 20. The cleaning member 30 is driven to move along the axial direction of the fan 20 by the driving assembly 40, so that the cleaning range of the cleaning member 30 can cover the whole area of the fan 20 along the axial direction, and the overall cleaning of the fan 20 can be realized. In addition, through the setting of cleaning member 30, need not to take apart the air conditioner and can realize fan 20's self-cleaning, convenient and fast has promoted user experience.

In addition, the cleaning member 30 is disposed between the heat exchanger 10 and the fan 20, and condensed water on the surface of the heat exchanger 10 can catch and adsorb dust generated during cleaning, thereby reducing flying of the dust in the air duct and reducing influence of the dust on indoor air quality.

Alternatively, as shown in connection with FIG. 3, the arc of cleaning members 30 is consistent with the arc of fan 20.

The radian of the cleaning member 30 is consistent with that of the fan 20, so that the cleaning member 30 can better fit the surface of the fan 20, dead angle cleaning is reduced, and the cleaning efficiency of the cleaning member 30 is improved.

Alternatively, as shown in conjunction with fig. 2 and 3, the cleaning member 30 extends downward in the circumferential direction of the fan 20.

When the air conditioner is a wall-mounted air conditioner, the cross flow fan 20 in the air conditioner indoor unit 80 is generally located between the heat exchanger 10 and the air outlet. The heat exchanger 10 is disposed adjacent to the fan 20 so that efficient heat exchange is possible when air flows through the heat exchanger 10. The drip tray 70 is typically disposed below the heat exchanger 10.

The cleaning member 30 extends downward along the circumference of the fan 20, so that dust cleaned by the cleaning member 30 can be effectively guided to be collected downward along the cleaning member 30, and the dust can fall into the dust containing mechanism such as the water pan 70 under the action of gravity, thereby improving the dust collecting effect.

Alternatively, as shown in fig. 3, 7, 9 and 14, the driving assembly 40 includes a screw 41 and a nut 42, the screw 41 is disposed between the heat exchanger 10 and the fan 20 and extends in an axial direction of the fan 20, the nut 42 is in driving connection with the screw 41, and the nut 42 is connected with the cleaning member 30, wherein the screw 41 is rotated to drive the nut 42 to move in the axial direction of the fan 20, thereby driving the cleaning member 30 to move in the axial direction of the fan 20.

The screw 41 transmission system has higher transmission efficiency, and the screw 41 extends along the axial direction of the fan 20 and can drive the nut 42 and the cleaning piece 30 to move along the axial direction of the fan 20, so that automatic cleaning of the fan 20 is realized. The mating transmission engagement of the screw 41 and the nut 42 can provide precise linear motion control so that the cleaning member 30 can be smoothly and accurately moved in the axial direction of the fan 20, improving cleaning effect. Meanwhile, the transmission structure of the screw 41 and the nut 42 is simple, and the screw is easy to maintain and replace.

Alternatively, as shown in connection with fig. 7, the length of the screw 41 is adapted to the length of the fan 20 in the axial direction.

The length of the screw 41 is adapted to the length of the fan 20 in the axial direction, which means that the length of the screw 41 is the same as the length of the fan 20 in the axial direction, or that the length of the screw 41 is longer than the length of the fan 20 in the axial direction, so that the transmission length of the screw 41 to the cleaning member 30 can cover the entire area of the fan 20 in the axial direction. This allows cleaning members 30 to clean the entire length of fan 20, improving the overall cleaning.

Alternatively, as shown in fig. 5, 6, 9 and 14, the indoor unit 80 of the air conditioner further includes a supporting frame 50, the supporting frame 50 is disposed between the heat exchanger 10 and the fan 20 and extends along an axial direction of the fan 20, the screw 41 is disposed on the supporting frame 50, and the screw 41 is rotatably connected with the supporting frame 50.

By providing the support frame 50 between the heat exchanger 10 and the fan 20, both the support frame 50 and the screw 41 extend in the axial direction of the fan 20, and the screw 41 is provided to the support frame 50, stability and structural strength of the screw 41 can be enhanced. The screw 41 is rotatably connected with the supporting frame 50, so that the screw 41 is more stable in the operation process. Meanwhile, the whole structure is more compact, and the occupation of the air duct space is saved.

Optionally, as shown in fig. 13 and 14, the indoor unit of an air conditioner further includes a pressing cover 54, the supporting framework 50 is provided with a first clamping groove, the pressing cover 54 is correspondingly arranged with the first clamping groove 501, the pressing cover 54 is connected with the supporting framework 50, the pressing cover is provided with a second clamping groove 541, the second clamping groove 541 and the first clamping groove 501 enclose a limit space 55 together, the screw 41 is penetrated in the limit space 55, and the screw 41 can rotate relative to the limit space 55.

The pressing cover 54 is connected to the supporting frame 50, and can firmly fix the screw 41 in the limit space 55. This can provide a stable support point for the screw 41, and improve the stability of the screw 41.

Optionally, the gland 54 is removably coupled to the support frame 50.

The gland 54 is detachably connected with the supporting framework 50, so that the assembling and disassembling process between the screw 41 and the supporting framework 50 is simpler and more convenient. The removable gland 54 may be quickly removed when maintenance, repair or replacement of the lead screw 41 or support frame 50 is required.

Alternatively, as shown in conjunction with fig. 5 and 6, the heat exchanger 10 includes a side tube plate 11, the side tube plate 11 being located at an end side 21 of the fan 20 in the axial direction, and both ends of the support frame 50 being connected to the side tube plate 11.

Both ends of the supporting frame 50 are connected to the side tube plates 11, and structural stability of the supporting frame 50 can be achieved. It will be appreciated that the air conditioner indoor unit includes a housing, and that both ends of the supporting frame 50 may be connected to side panels of the housing. Both ends of the screw 41 may be rotatably connected to the side tube plates 11 of the heat exchanger 10 or to side plates of the housing.

Alternatively, as shown in fig. 13 and 14, the supporting frame 50 is provided with a slide groove 52, and the screw 41 is provided in the slide groove 52 and is rotatable in the slide groove 52.

The lead screw 41 is arranged on the supporting framework 50, and the chute 52 can provide necessary rotation space for the lead screw 41, so that the normal operation of the lead screw 41 is prevented from being influenced. Meanwhile, the sliding groove 52 can also form a limiting effect on the screw 41, so that the screw 41 is prevented from excessively moving or falling off in the running process, and the stability of the screw 41 can be improved.

Alternatively, as shown in connection with fig. 2-4, the cleaning member 30 is rotatably coupled to the nut 42 such that the cleaning member 30 can rotate in the radial direction of the fan between an operative position in contact with the fan 20 and an inoperative position spaced apart from the fan 20.

As shown in fig. 2, the cleaning elements are in the operative position. As shown in fig. 4, the cleaning elements are in the rest position, the direction indicated by the arrow in fig. 4 being radial to the fan. The cleaning member 30 can move along the axial direction of the fan 20 under the drive of the nut 42, so as to clean the fan 20 in all aspects along the axial direction. At the same time, the rotational connection between the cleaning member 30 and the nut 42 is capable of rotating in the radial direction of the fan toward the fan 20 or away from the fan 20. When the cleaning member 30 rotates toward the fan 20, the cleaning member 30 can be rotated to an operating position contacting the fan 20, and the cleaning member 30 is in an operating state at this time, thereby cleaning the fan 20. When the cleaning member 30 is rotated away from the fan 20 toward the heat exchanger 10, it can be rotated to a non-operating position separated from the fan 20, and the cleaning member 30 is in a non-operating state at this time, so that the normal air supply operation of the fan 20 can be prevented from being affected. This can improve the flexibility and adaptability of the cleaning member 30, make the cleaning process more efficient, and avoid affecting the normal operation of the air conditioner.

Alternatively, as shown in fig. 10, the nut 42 is provided with a first stopper 421, the cleaning member 30 is provided with a first stopper engaging portion 32, and the first stopper 421 engages with the first stopper engaging portion 32 to limit the rotation angle of the cleaning member 30 toward the working position.

The cleaning member 30 can be rotated to an operating position contacting the fan 20 when rotated toward the fan 20. When the cleaning member 30 is in the operating state, the fan 20 is also in the rotating state, and the cleaning member 30 can clean the entire circumferential area of the fan 20 by the rotation of the fan 20. By the first stopper 421 being engaged with the first stopper engagement portion 32, the rotation angle of the cleaning member 30 toward the fan 20 can be restricted, thereby defining the operation position of the cleaning member 30. In this way, the positioning accuracy of the cleaning member 30 at the working position can be improved, and the influence on the rotation of the fan 20 due to the overlarge rotation angle of the cleaning member 30 at the working position can be prevented. Damage caused by excessive rotation of the cleaning member 30 can also be avoided by limiting the stopper of the cleaning member 30 in the operating position.

Alternatively, as shown in fig. 10, the first stopper 421 includes a first stopper surface 422, and the first stopper engaging portion 32 includes a first stopper engaging surface 321, and the first stopper surface 422 engages with the first stopper engaging surface 321 to limit the rotation angle of the cleaning member 30 toward the working position.

The first stop surface 422 and the first stop mating surface 321 abut against each other, so that the working position can be precisely limited, and the cleaning member 30 can be properly contacted with the fan 20 in the working position. The first stop surface 422 abuts against the first stop matching surface 321, so that effective limit is formed on the cleaning piece 30, and the cleaning piece 30 can be prevented from continuing to rotate after moving to the working position. This can prevent the cleaning member 30 from rotating in a direction toward the operating position in a short way and not coming into contact with the fan 20, and can prevent damage caused by excessive rotation of the cleaning member 30.

Alternatively, as shown in fig. 10, the supporting frame 50 is provided with a second stopper 51, the cleaning member 30 is provided with a second stopper engaging portion 33, and the second stopper 51 engages with the second stopper engaging portion 33 to limit the rotation angle of the cleaning member 30 toward the non-operating position.

The cleaning member 30 can be rotated to a non-operating position separated from the fan 20 when rotated toward the heat exchanger 10 away from the fan 20. By the engagement of the second stopper 51 and the second stopper engagement 33, the rotation angle of the cleaning member 30 toward the non-operating position can be restricted, thereby defining the non-operating position of the cleaning member 30. Thus, the positioning accuracy of the cleaning member 30 in the non-working position can be improved, and the cleaning member 30 or the evaporator is prevented from being damaged due to the overlarge rotation angle of the cleaning member 30 in the non-working position.

Alternatively, as shown in connection with fig. 10, the second stopper 51 includes a second stopper surface 511, and the second stopper fitting portion 33 includes a second stopper fitting surface 331, and the second stopper surface 511 cooperates with the second stopper fitting surface 331 to limit the rotation angle of the cleaning member 30 toward the rest position.

The second stop surface 511 and the second stop mating surface 331 abut to precisely limit the non-operative position to better separate the cleaning member 30 from the fan 20 in the non-operative position. By the second stop surface 511 abutting against the second stop mating surface 331, an effective limit is formed on the cleaning member 30, and the cleaning member 30 can be prevented from continuing to rotate after moving to the rest position. This can prevent damage caused by excessive rotation of the cleaning member 30 toward the rest position.

Alternatively, as shown in connection with fig. 12, the supporting frame 50 is provided with a positioning portion 53, the nut 42 is provided with a positioning engaging portion 423, and the positioning portion 53 engages with the positioning engaging portion 423 to restrict the rotation of the nut 42 with respect to the supporting frame 50.

The lead screw 41 is arranged on the supporting framework 50, the lead screw 41 is rotationally connected with the supporting framework 50, and the lead screw 41 can drive the nut 42 to move relative to the supporting framework 50 along the axial direction of the fan 20 through rotation, so that the nut 42 drives the cleaning piece 30 to move along the axial direction of the fan 20. By the engagement of the positioning portion 53 with the positioning engaging portion 423, the rotation of the nut 42 with respect to the support frame 50 can be restricted, so that the nut 42 can be prevented from being shifted or rotated during the movement. This can promote stability of the nut 42 during driving, thereby enabling the cleaning member 30 to accurately move along a predetermined path, and improving cleaning effect.

Alternatively, as shown in fig. 12, the positioning portion 53 includes a first limiting surface 531 and a second limiting surface 532, where the first limiting surface 531 and the second limiting surface 532 are disposed on the chute 52, the positioning mating portion 423 includes a first limiting mating surface 424 and a second limiting mating surface 425, the first limiting surface 531 is mated with the first limiting mating surface 424 to prevent the nut 42 from rotating toward the fan 20, and the second limiting surface 532 is mated with the second limiting mating surface 425 to prevent the nut 42 from rotating toward the heat exchanger 10.

The positioning portion 53 is disposed on the supporting frame 50, and the positioning portion 53 includes a first limiting surface 531 and a second limiting surface 532, where the first limiting surface 531 and the second limiting surface 532 are both disposed on the chute 52 of the supporting frame 50. The positioning mating portion 423 is disposed on the nut 42, where the positioning mating portion 423 includes a first limiting mating surface 424 and a second limiting mating surface 425, and the first limiting mating surface 424 and the second limiting mating surface 425 may be disposed on a surface of the nut 42. The first stop surface 531 and the first stop mating surface 424 cooperate to prevent the nut 42 from rotating toward the fan 20. The second stop surface 532 and the second stop mating surface 425 cooperate to prevent rotation of the nut 42 toward the heat exchanger 10. This can fix the nut 42 in two main rotational directions, so that the nut 42 can be effectively prevented from rotating relative to the support frame 50.

Optionally, the driving assembly 40 further comprises a motor in driving connection with the screw 41, and the motor is provided outside the side tube plate 11 of the heat exchanger 10.

The screw 41 is driven to rotate by the power of the motor, and the cleaning member 30 can be driven to move smoothly. The motor is arranged on the outer side of the side tube plate 11, so that the occupation of the air channel space on the inner side of the side tube plate 11 can be avoided, the heat dissipation and the maintenance of the motor are facilitated, and meanwhile, the motor is convenient to install and replace.

Alternatively, as shown in conjunction with fig. 3 and 10, the cleaning member 30 includes a brush 31.

The brush 31 has better softness and flexibility, and can better fit the surface of the fan 20, thereby achieving more comprehensive cleaning. The brush 31 can also be adapted to various shapes of surfaces including curved portions of the blades of the fan 20, effectively removing dust and dirt attached to the fan 20. The brush 31 is used as the cleaning member 30, which not only improves cleaning efficiency but also reduces damage to the blades of the fan 20. In addition, the brush material is generally durable and can withstand repeated use, and is suitable for use as a long-term cleaning tool.

It will be appreciated that the cleaning member 30 may also be a sponge, cloth pad, rubber, or like cleaning material.

Alternatively, as shown in connection with fig. 14, the cleaning member 30 includes a first cleaning section 34 and a second cleaning section 35, the first cleaning section 34 is drivingly connected to the driving assembly 40 and extends in an arc shape along the circumferential direction of the fan 20, and the second cleaning section 35 is connected to the first cleaning section 34 and extends in the axial direction of the fan 20.

The cleaning member 30 extends in an arc shape entirely along the circumferential direction of the fan 20, and the cleaning member 30 includes a first cleaning section 34 and a second cleaning section 35. The first cleaning stage 34 extends in an arc shape along the circumferential direction of the fan 20 to form an arc strip structure. The second cleaning section 35 extends along the axial direction of the fan 20 relative to the first cleaning section 34, and the second cleaning section 35 can compensate for the dead space of the first cleaning section 34 along the axial direction of the fan 20 when the cleaning member 30 moves along the axial direction of the fan 20. Meanwhile, the second cleaning section 35 is also arc-shaped along the circumferential direction of the fan 20, and can be effectively attached to the surface of the fan 20. By the combination of the first cleaning stage 34 and the second cleaning stage 35, the cleaning effect of the cleaning member 30 can be effectively improved. The second cleaning section 35 is disposed at an end of the first cleaning section 34 remote from the driving assembly 40, such that the cleaning member 30 has a T-shaped or T-shaped-like structure. The second cleaning section 35 may be provided at other positions of the first cleaning section 34 in the circumferential direction of the fan. It will be appreciated that the second cleaning section 35 may also be provided at an end of the first cleaning section 34 adjacent to the drive assembly 40, the second cleaning section 35 being in driving connection with the drive assembly.

Alternatively, as shown in conjunction with fig. 6 and 7, the driving assembly 40 drives the cleaning member 30 between the first end side 211 and the second end side 212 of the fan 20 in the axial direction, and the cleaning member 30 can be separated from the fan 20 when the cleaning member 30 is located at the first end side 211 and/or the second end side 212.

The driving assembly 40 drives the cleaning member 30 to move between the first end side 211 and the second end side 212 of the fan 20 in the axial direction, enabling full cleaning of the fan 20. The cleaning member 30 can be separated from the fan 20 when the cleaning member 30 is located at the first end side 211 and/or the second end side 212. The cleaning member 30 can be automatically moved to the first end side 211 or the second end side 212 of the fan 20 when cleaning is not required, and the cleaning member 30 is in a non-operating state at this time, so that the normal operation of the fan 20 can be prevented from being affected.

Alternatively, as shown in fig. 6, 7 and 9, the number of cleaning members 30 is plural, and the plural cleaning members 30 include a first cleaning member 36 and a second cleaning member 37, the first cleaning member 36 being movable to the first end side 211, and the second cleaning member 37 being movable to the second end side 212.

The provision of the plurality of cleaning members 30 can enhance cleaning efficiency. The first cleaning member 36 can move to the first end side 211 in the non-working state, and the second cleaning member 37 can move to the second end side 212 in the non-working state, so that the separation of the first cleaning member 36 and the second cleaning member 37 from the fan 20 is realized, and the normal air supply operation of the fan 20 is prevented from being influenced.

Optionally, as shown in fig. 4, 7 and 8, the indoor unit of the air conditioner further includes a limiting portion 60, where the limiting portion 60 is disposed at a first end side 211 and/or a second end side 212 of the fan 20 in an axial direction, and the limiting portion 60 cooperates with the cleaning member 30 to limit the cleaning member 30 to a non-working position separated from the fan 20.

When the cleaning member 30 is located at the first end side 211 and/or the second end side 212, the stopper 60 is engaged with the cleaning member 30, so that the cleaning member 30 can be restricted to the non-operating position separated from the fan 20. Thus, the cleaning member 30 can be stably maintained at the non-operating position in the non-operating state, thereby avoiding the interference of the cleaning member 30 to the fan 20 when the air conditioner is operated, and enabling the air conditioner to be operated normally. When the fan 20 needs to be cleaned, the driving assembly 40 drives the cleaning member 30 to move along the axial direction of the fan 20, so that the cleaning member 30 and the limiting part 60 are released from limiting fit, and the cleaning member 30 can move to the working position.

Optionally, as shown in fig. 8, the limiting portion 60 includes a limiting blocking surface 61, where the limiting blocking surface 61 is disposed at an end of the limiting portion 60 facing away from the fan 20, and the cleaning member 30 can abut against the limiting blocking surface 61 to limit the movement of the cleaning member 30 toward the fan 20.

The limiting blocking surface 61 is arranged at one end of the limiting part 60, which is away from the fan 20, and the limiting blocking surface 61 can be propped against the cleaning piece 30, so that the cleaning piece 30 is separated from the fan 20, and the cleaning piece 30 is stably limited at the non-working position. When the cleaning member 30 abuts against the limiting stop surface 61, the cleaning member 30 can be limited to move toward the fan 20, so that the cleaning member 30 is prevented from affecting the air supply operation of the fan 20.

Optionally, the stop surface 61 extends in the axial direction of the fan 20.

The stopper 60 is located at the axial end 21 of the fan 20, and the stopper surface 61 extends in the axial direction of the fan 20, so that the cleaning member 30 can be effectively stopped at the non-operating position separated from the fan 20. The spacing baffle surface 61 is located the one end that spacing portion 60 deviates from fan 20, and spacing baffle surface 61 extends along the axial of fan 20, under the circumstances that drive assembly 40 drive cleaning member 30 moves along the axial of fan 20, can increase the area of contact between spacing baffle surface 61 and the cleaning member 30 to improve spacing effect.

Alternatively, as shown in fig. 7 and 8, the axial end side 21 of the fan 20 includes a first end side 211 and a second end side 212, and the stopper surface 61 is inclined away from the fan 20 axis in a direction toward the first end side 211 in the middle of the fan 20 in the case where the stopper 60 is provided at the first end side 211, and the stopper surface 61 is inclined away from the fan 20 axis in a direction toward the second end side 212 in the middle of the fan 20 in the case where the stopper 60 is provided at the second end side 212.

The axis of fan 20, i.e., the axial centerline of fan 20, fan 20 rotates about the axis of fan 20. The middle of the fan 20 refers to the middle of the fan 20 in the axial direction. In the case where the stopper 60 is provided at the first end side 211, the cleaning member 30 can move to the first end side 211 in the axial direction of the fan 20, and is engaged with the stopper 60 at the first end side 211. At this time, the stopper surface 61 is inclined away from the axis of the fan 20 in a direction toward the first end side 211 in the middle of the fan 20, and can guide the cleaning member 30 to move away from the fan 20. This effectively guides the movement of the cleaning member 30 to the inactive position separated from the fan 20. In the case where the stopper 60 is provided at the second end side 212, the cleaning member 30 can be moved to the second end side 212 in the axial direction of the fan 20, and is engaged with the stopper 60 at the second end side 212. At this time, the stopper surface 61 is inclined away from the axis of the fan 20 in a direction toward the second end side 212 in the middle of the fan 20, and can guide the cleaning member 30 to move away from the fan 20. This effectively guides the movement of the cleaning member 30 to the inactive position separated from the fan 20.

Optionally, as shown in fig. 11, the driving assembly 40 further includes a reset element 43, where the reset element 43 is connected to the cleaning element 30 to drive the cleaning element 30 to reset from a non-operating position separated from the fan 20 to an operating position contacting the fan 20.

Illustratively, the cleaning members 30 are rotatable between an operative position in contact with the fan 20 and an inoperative position spaced apart from the fan 20. In the operating state, the cleaning member 30 is rotatable to an operating position in contact with the fan 20, and the cleaning member 30 moves between the first end side 211 and the second end side 212 of the fan 20 in the axial direction of the fan 20, thereby achieving cleaning of the fan 20. In the non-operating state, the cleaning member 30 is stopped after being moved to the first end side 211 or the second end side 212 of the fan 20, and is rotatable to a non-operating position separated from the fan 20. When the fan 20 needs to be started again in the working state, the driving assembly 40 drives the cleaning member 30 to move along the axial direction of the fan 20, and meanwhile, the resetting member 43 drives the cleaning member 30 to rotate towards the fan 20, so that the cleaning member 30 can be reset to the working position.

The cleaning member 30 is separated from the fan 20 in the non-working position, and the cleaning member 30 can be driven to automatically reset to the working position contacting with the fan 20 under the action of the resetting member 43. Therefore, the degree of automation of the cleaning system can be improved, manual intervention is reduced, and the cleaning process is more convenient and efficient. Meanwhile, under the action of the restoring force of the restoring member 43, a supporting force towards the fan 20 can be formed on the cleaning member 30, and the contact effect of the cleaning member 30 and the fan 20 in the working state is improved.

Optionally, as shown in fig. 10, the restoring member 43 is a torsion spring 431, the cleaning member 30 is rotationally connected with the nut 42 through a rotation shaft 44, the torsion spring 431 is sleeved on the rotation shaft 44, one end of the torsion spring 431 abuts against the nut 42, the other end of the torsion spring 431 abuts against the cleaning member 30, and the torsion spring 431 is elastically deformed when the cleaning member 30 rotates to the non-working position.

The torsion spring 431 is simple in structure and can provide a stable and continuous restoring force. The elastic deformation of the torsion spring 431 is utilized to store and release energy, thereby realizing the automatic reset of the cleaning member 30. This allows the cleaning member 30 to maintain an appropriate tension during cleaning, to enhance cleaning effect, and to be returned to the working position promptly and accurately when cleaning is required.

Alternatively, the shaft 44 may be a pin.

The cleaning member 30 and the nut 42 are fixedly coupled by a pin. The cleaning member 30 is rotatable relative to the nut 42 between an operative position and an inoperative position with the pin as the shaft 44.

Optionally, as shown in fig. 2, the indoor unit of the air conditioner further includes a water tray 70, the water tray 70 is disposed below the heat exchanger 10, and the water tray 70 corresponds to the cleaning member 30.

The water pan 70 is provided under the heat exchanger 10 and corresponds to the cleaning member 30, and can effectively collect dust falling during cleaning. Meanwhile, the water pan 70 may also effectively collect condensed water generated during the cooling process of the heat exchanger 10. Dust is collected by the water pan 70, so that secondary pollution caused by flying of the dust into the air in the cleaning process is avoided, and the air supply quality can be improved. In the case where the cleaning member 30 extends downward in the circumferential direction of the fan 20, the cleaning member 30 can better guide dust to fall into the lower drip tray 70, so that dust can be collected more efficiently.

Alternatively, the heat exchanger 10 is a multi-stage evaporator including a plurality of evaporator stages, and the cleaning member 30 is disposed between the lowermost evaporator stage and the fan 20.

The multi-stage evaporator can promote the flexibility of space utilization and can be more compactly arranged in the indoor unit of the air conditioner. When the air conditioner is a wall-mounted air conditioner, the water pan 70 is provided below the lowermost evaporator section. By disposing the cleaning member 30 between the lowermost evaporator section and the fan 20, the distance between the cleaning member 30 and the water tray 70 can be reduced, thereby reducing the risk of dust spreading in the air, and improving the dust collecting effect.
