The brush can cover the entire length of the blower fan and is slightly longer than the length of the blower fan itself. By abutting against the blower fan, the brush can clean and remove dust from the blower fan.

[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 long, narrow brush is used to clean the air blower, and the length of the brush is slightly longer than the length of the air blower. However, the long, narrow brush does not make sufficient contact with the air blower, which affects the cleaning effect.

[0055] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0056] Combination Figure 1-14As shown, this embodiment of the present disclosure provides a cleaning device 30 for an indoor unit of an air conditioner. The indoor unit includes a housing 10 and a fan 20. The housing 10 has an internal space 11, and the fan 20 is disposed in the internal space 11. The cleaning device 30 includes a cleaning component 40 and a support frame 50. The cleaning component 40 is adapted to be disposed in the internal space 11 and located beside the fan 20, and the cleaning component 40 extends along the axial direction of the fan 20. The support frame 50 is adapted to be supported within the internal space 11, and the support frame 50 is correspondingly disposed to the cleaning component 40. The cleaning component 40 is provided with a connecting mating part 41, and the support frame 50 is provided with a connecting part 51. The connecting part 51 and the connecting mating part 41 cooperate to connect the cleaning component 40 and the support frame 50.

[0057] The axial direction of fan 20 is as follows Figure 1 and Figure 7 As shown, the cleaning component 40 extends along the axial direction of the fan 20. The length of the cleaning component 40 is the same as the axial length of the fan 20, or the length of the cleaning component 40 is longer than the axial length of the fan 20. This allows the cleaning component 40 to cover the entire axial length of the fan 20, thereby improving cleaning efficiency.

[0058] The cleaning device 30 for an indoor unit of an air conditioner provided in this embodiment has a cleaning component 40 extending axially along the fan 20, covering the entire axial length of the fan 20 and providing more comprehensive cleaning, thereby improving cleaning efficiency. The cleaning component 40 is connected to a support frame 50, which supports the cleaning component 40 and enhances its stability. This allows the cleaning component 40 to make close contact with the fan 20, thereby improving the cleaning effect on the fan 20.

[0059] Furthermore, the automatic cleaning and dust removal function of fan 20 significantly improves the maintenance efficiency of the air conditioner. It eliminates the need to disassemble fan 20 components, reducing manual intervention and simplifying operation. The automatic cleaning of fan 20 by cleaning component 40 reduces dust accumulation, improves airflow quality, and thus enhances air conditioner performance. The automated dust removal function eliminates user concerns about dust accumulation on fan 20, thereby improving the overall user experience. Fan 20 can be a cross-flow fan 20.

[0060] Optionally, the cleaning component 40 is rotatably connected to the support frame 50, and the cleaning component 40 can rotate between a working position in contact with the fan 20 and a non-working position separated from the fan 20.

[0061] The direction of rotation of the cleaning component is as follows Figure 4 As shown. The support frame 50 is supported in the internal space 11 and is fixedly connected to the housing 10 or other components of the indoor unit of the air conditioner. The support frame 50 supports and limits the cleaning component 40, and the cleaning component 40 is rotatably connected to the support frame 50. Figure 4 and Figure 5 As shown, when fan 20 needs cleaning, cleaning component 40 rotates towards fan 20 to the working position. In the working position, cleaning component 40 contacts fan 20, enabling effective cleaning of fan 20. When cleaning component 40 is in working condition, fan 20 starts rotating, allowing cleaning component 40 to clean the entire circumferential area of ​​fan 20. Figure 2 and Figure 3 As shown, when the fan 20 does not require cleaning, it is rotated to a non-working position. In the non-working position, the cleaning component 40 is separated from the fan 20, which avoids affecting the normal operation of the fan 20. At the same time, the cleaning component 40 can switch between the working and non-working positions by rotating, which improves the flexibility of the cleaning component 40's position adjustment, allowing the cleaning component 40 to respond to different work needs in a timely manner.

[0062] When the indoor unit of the air conditioner is a wall-mounted indoor unit, both the fan 20 and the cleaning component 40 are set in a horizontal direction. The cleaning component 40 can be rotated to a non-working position by rotating upward or downward from the working position.

[0063] Optionally, combined Figure 3 and Figure 5 As shown, the connecting part 41 includes a rotating shaft 411, and the connecting part 51 includes a limiting groove 511. The rotating shaft 411 is rotatably embedded in the limiting groove 511 so that the cleaning component 40 is rotatably connected to the support frame 50. The rotating shaft 411 and the limiting groove 511 both extend along the axial direction of the fan 20 so that the cleaning component 40 can rotate around the rotating shaft 411 between the working position and the non-working position.

[0064] The rotating connection between the cleaning component 40 and the support frame 50 is achieved through the rotating engagement structure of the rotating shaft 411 and the limiting groove 511. Both the rotating shaft 411 and the limiting groove 511 extend along the axial direction of the fan 20. The rotating shaft 411 is embedded within the limiting groove 511, allowing the cleaning component 40 to rotate around the rotating shaft 411, thus switching between working and non-working positions. Furthermore, the rotating connection between the rotating shaft 411 and the limiting groove 511 reduces direct contact between the cleaning component 40 and the support frame 50, reducing wear and extending the service life of the cleaning component 40. The rotating connection of the cleaning component 40 around the rotating shaft 411 simplifies the rotation operation of the cleaning component 40, allowing it to be easily moved to either the working or non-working position, thus improving the ease of use of the cleaning component 40.

[0065] Optionally, combined Figure 12 and Figure 14 As shown, the limiting groove 511 extends in an arc shape to fit the outer surface of the rotating shaft 411.

[0066] The arc-shaped limiting groove 511 is adapted to the outer surface of the rotating shaft 411, which allows the rotating shaft 411 to rotate smoothly within the limiting groove 511, improving the fitting accuracy between the rotating shaft 411 and the limiting groove 511, thereby enhancing the rotational stability of the cleaning component 40.

[0067] Optionally, combined Figure 8 As shown, the support frame 50 has through holes 54 at both ends along the axial direction of the fan 20, and the rotating shaft 411 is located in the middle of the cleaning component 40 along the axial direction of the fan 20. The two ends of the cleaning component 40 along the axial direction of the fan 20 pass through the through holes 54 and are rotatably connected to the support frame 50.

[0068] By providing through holes 54 at both ends of the support frame 50, and having both ends of the cleaning component 40 pass through the through holes 54, the stability of the cleaning component 40 can be improved.

[0069] Optionally, combined Figure 10 and Figure 13 As shown, the connecting part 41 also includes a buckle 412, which is disposed on the rotating shaft 411; the connecting part 51 also includes a slot 513, which is formed in the groove wall 512 of the limiting groove 511, and the slot 513 engages with the buckle 412 to prevent the cleaning part 40 from moving towards the fan 20 in the radial direction of the fan 20; wherein, the buckle 412 is rotatable relative to the slot 513 around the rotating shaft 411.

[0070] The radial direction of fan 20 is as follows Figure 2 As indicated by the arrow, the cleaning component 40 is rotatably connected to the limiting groove 511 of the support frame 50 via a rotating shaft 411. A slot 513 is provided in the groove wall 512 of the limiting groove 511, and a buckle 412 is provided on the rotating shaft 411. The buckle 412 engages with the slot 513, preventing the cleaning component 40 from moving radially toward the fan 20. This increases the connection strength between the cleaning component 40 and the support frame 50, making it less prone to radial displacement of the cleaning component 40 during operation, effectively improving the stability of the cleaning component 40. The connection between the cleaning component 40 and the support frame 50 via the buckle 412 and slot 513 not only limits the movement of the cleaning component 40 but also prevents it from deforming due to force during cleaning.

[0071] During the rotation of the cleaning component 40 around the rotating shaft 411 between the working position and the non-working position, the rotating shaft 411 can also rotate relative to the limiting groove 511 at the same time. When the rotating shaft 411 rotates, it can drive the buckle 412 to rotate synchronously around the rotating shaft 411. This makes the engagement between the buckle 412 and the bayonet 513 prevent the cleaning component 40 from moving radially toward the fan 20, while also avoiding affecting the rotation of the cleaning component 40 between the working position and the non-working position.

[0072] Optionally, combined Figure 10 As shown, the latch 412 includes a first latch 413 and a second latch 414. The latch 513 includes a third sidewall 514 and a fourth sidewall 515 that are axially opposite to each other along the pivot 411. The first latch 413 engages with the third sidewall 514 and can rotate along the third sidewall 514. The second latch 414 engages with the fourth sidewall 515 and can rotate along the fourth sidewall 515.

[0073] The axial direction of the rotating shaft 411 is the same as the axial direction of the fan 20. The first claw 413 engages with the third side wall 514, and the second claw 414 engages with the fourth side wall 515, preventing the latch 412 from moving radially toward the fan 20 relative to the latch 513. The first claw 413 rotates along the third side wall 514, and the second claw 414 rotates along the fourth side wall 515, allowing the latch 412 to rotate around the rotating shaft 411 relative to the latch 513.

[0074] Optionally, combined Figure 10 As shown, the third sidewall 514 and the fourth sidewall 515 extend in an arc shape along the circumference of the pivot 411.

[0075] Circumferential direction of shaft 411 Figure 9 As shown. The arc-shaped third sidewall 514 and fourth sidewall 515 enable the first claw 413 and the second claw 414 to rotate smoothly along the circumference of the pivot 411, thereby improving the stability of the buckle 412 rotating around the pivot 411.

[0076] Optionally, combined Figure 2-5 As shown, the support frame 50 is located on the side of the cleaning component 40 away from the fan 20.

[0077] The support frame 50 is located on the side of the cleaning component 40 away from the fan 20, which can optimize the layout of the internal space 11, so that the support frame can stably support the cleaning component 40 without affecting the cleaning work of the cleaning component 40.

[0078] Optionally, combined Figure 9 and Figure 10 As shown, the support frame has a 50mm hollowed-out design.

[0079] The hollow design of the support frame 50 reduces the amount of material used, thereby reducing its overall weight. The hollow design of the support frame 50 also reduces the impact on airflow within the internal space 11 of the housing.

[0080] Optionally, combined Figure 10 and Figure 13As shown, the cleaning component 40 is provided with a limiting engagement part 42, and the support frame 50 is provided with a first limiting part 52. The limiting engagement part 42 and the first limiting part 52 cooperate to limit the rotation angle of the cleaning component 40 toward the working position. When the connecting engagement part 41 includes a buckle 412 and the connecting part 51 includes a latch 513, the limiting engagement part 42 is the buckle 412, and the first limiting part 52 is the latch 513. The first side wall 521 along the circumference of the rotating shaft 411 is used. When in the working position, the buckle 412 abuts against the first side wall 521.

[0081] When the cleaning component 40 rotates toward the working position, it drives the limiting engagement part 42 to rotate synchronously. When the limiting engagement part 42 rotates to engage with the first limiting part 52, it prevents the cleaning component 40 from continuing to rotate, thereby limiting the rotation angle of the cleaning component 40 toward the working position. This precisely limits the working position of the cleaning component 40, preventing the cleaning component 40 from rotating too much in the working position and affecting the rotation of the fan 20. By limiting the cleaning component 40 in the working position, damage caused by excessive rotation of the cleaning component 40 can also be avoided.

[0082] Combination Figure 10 and Figure 13 As shown, when the connecting part 41 includes a snap fastener 412 and the connecting part 51 includes a latch 513, the snap fastener 412 can be directly used as a limiting part 42. When the cleaning component 40 rotates, the snap fastener 412 can rotate relative to the latch 513 around the pivot 411, that is, the snap fastener 412 can rotate circumferentially along the pivot 411. The latch 513 includes a first sidewall 521 arranged circumferentially along the pivot 411. When the snap fastener 412 rotates circumferentially along the pivot 411 until it abuts against the first sidewall 521, the cleaning component 40 can be limited to the working position.

[0083] Optionally, combined Figure 10 and Figure 13 As shown, the cleaning component 40 is provided with a limiting engagement part 42, and the support frame 50 is provided with a second limiting part 53. The limiting engagement part 42 and the second limiting part 53 cooperate to limit the rotation angle of the cleaning component 40 toward the non-working position. When the connecting part 51 includes a buckle 412 and the connecting engagement part 41 includes a latch 513, the limiting engagement part 42 is the buckle 412, and the second limiting part 53 is the second side wall 531 of the latch 513 along the circumference of the rotating shaft 411. When in the non-working position, the buckle 412 abuts against the second side wall 531.

[0084] When the cleaning component 40 rotates toward the non-working position, it drives the limiting engagement part 42 to rotate synchronously. When the limiting engagement part 42 rotates to engage with the second limiting part 53, it prevents the cleaning component 40 from continuing to rotate, thereby limiting the rotation angle of the cleaning component 40 toward the non-working position. This precisely limits the non-working position of the cleaning component 40, preventing damage caused by excessive rotation angle of the cleaning component 40 in the non-working position.

[0085] Combination Figure 10 and Figure 13 As shown, when the connecting part 41 includes a snap fastener 412 and the connecting part 51 includes a latch 513, the latch 513 includes a second sidewall 531 arranged circumferentially along the pivot 411, and the second sidewall 531 and the first sidewall 521 are arranged opposite each other circumferentially along the pivot 411. When the snap fastener 412 rotates circumferentially along the pivot 411 to abut against the second sidewall 531, the cleaning component 40 can be confined to a non-working position.

[0086] By engaging with the first limiting part 52 and the second limiting part 53 respectively, the cleaning part 40 can rotate within a specific angle range, precisely defining the working position and non-working position of the cleaning part 40.

[0087] Optionally, combined Figure 8 and Figure 11 As shown, the cleaning component 40 includes a first cleaning section 43 and a second cleaning section 44. The first cleaning section 43 extends along the axial direction of the fan 20; the second cleaning section 44 extends along the axial direction of the fan 20 and is connected to the first cleaning section 43.

[0088] The cleaning component 40 is configured as two parts: a first cleaning section 43 and a second cleaning section 44, which are connected to each other. This increases the rigidity of the cleaning component 40 and effectively prevents it from deforming during the cleaning process. It is understood that the cleaning component 40 can also be configured as a multi-segment structure, such as three or four segments.

[0089] Optionally, combined Figure 14 As shown, the first cleaning section 43 is provided with a snap-fit ​​part 431, and the second cleaning section 44 is provided with a snap-fit ​​mating part 441. The snap-fit ​​part 431 and the snap-fit ​​mating part 441 cooperate to make the first cleaning section 43 and the second cleaning section 44 snap-fit ​​together.

[0090] By engaging the snap-fit ​​part 431 and the snap-fit ​​mating part 441, the first cleaning section 43 and the second cleaning section 44 are connected in a snap-fit ​​manner, which can improve the connection stability between the first cleaning section 43 and the second cleaning section 44 and prevent relative displacement or separation of the first cleaning section 43 and the second cleaning section 44 during use.

[0091] Optionally, combined Figure 14As shown, the snap-fit ​​part 431 includes a snap-fit ​​groove 432, and the snap-fit ​​mating part 441 includes a snap-fit ​​protrusion 442, which can snap-fit ​​with the snap-fit ​​groove 432; when the connecting mating part 41 includes a rotating shaft 411, the rotating shaft 411 is located at one end of the first cleaning section 43 facing the second cleaning section 44, the snap-fit ​​groove 432 is opened in the rotating shaft 411, and the snap-fit ​​protrusion 442 is located at one end of the second cleaning section 44 facing the first cleaning section 43.

[0092] The snap-fit ​​structure of the protrusion 442 and the slot 432 is simple and has high connection stability. It can simplify the assembly and connection process between the first cleaning section 43 and the second cleaning section 44, and also enhance the reliability of the connection.

[0093] When the connecting part 41 includes a rotating shaft 411, the rotating shaft 411 is located at the end of the first cleaning section 43 facing the second cleaning section 44, and a slot 432 is formed inside the rotating shaft 411, while a protrusion 442 is located at the end of the second cleaning section 44 facing the first cleaning section 43. The slot 432, located inside the rotating shaft 411, allows for a more compact structure of the cleaning component 40. The protrusion 442 engages with the slot 432, connecting the end of the first cleaning section 43 to the end of the second cleaning section 44. The rotating shaft 411, located between the first cleaning section 43 and the second cleaning section 44, provides a rotational support point at the center of the cleaning component 40, thereby improving the stability of the cleaning component 40's rotation.

[0094] Optionally, combined Figure 14 As shown, the inner wall 433 of the slot 432 is polygonal, and the outer wall 443 of the protrusion 442 is polygonal. The inner wall 433 of the slot 432 and the outer wall 443 of the protrusion 442 are adapted to each other.

[0095] The inner wall 433 of the slot 432 is adapted to the outer wall 443 of the protrusion 442, meaning that the inner wall 433 of the slot 432 and the outer wall 443 of the protrusion 442 have the same number of polygons. When the protrusion 442 engages with the slot 432, the polygonal inner wall 433 and the polygonal outer wall 443 fit together, providing multiple engagement contact points and thus increasing the connection strength. This improves the stability of the cleaning component 40.

[0096] Optionally, combined Figure 14 As shown, the inner wall 433 of the slot 432 is hexagonal, and the outer wall 443 of the protrusion 442 is hexagonal.

[0097] The hexagon has symmetry. When the protrusion 442 and the slot 432 are engaged, the inner wall 433 and the outer wall 443 of the hexagon fit tightly together, which can distribute the force more evenly and improve the stability and reliability of the connection.

[0098] Optionally, combined Figure 8 and Figure 11 As shown, the cleaning component 40 includes a base 45 and a cleaning part 46. The base 45 is connected to the support frame 50, and the connecting mating part 41 is provided on the base 45. The cleaning part 46 is provided on the base 45 and can contact the fan 20.

[0099] The cleaning part 46 can contact the fan 20 for cleaning the fan 20. The cleaning part 46 is disposed on the base 45, which provides the necessary structural strength for the cleaning part 46 to maintain stable contact with the fan 20 during the cleaning process. The cleaning part 46 is disposed on the base 45, and the base 45 is connected to the support frame 50, which enhances the stability and durability of the entire cleaning component 40. The base 45 extends along the axial direction of the fan, and the rotating shaft 411 can be fitted onto the outside of the base.

[0100] Optionally, combined Figure 8 As shown, the cleaning component 40 includes a brush 48, a base 45 which is a brush shaft 481, and a cleaning part 46 which is a brush bristle 482, with the bristles distributed along the axial direction of the brush shaft.

[0101] The brush 48 is soft and flexible, allowing it to better conform to the surface of the fan 20 for a more thorough cleaning. The brush 48 can also adapt to surfaces of different shapes, effectively removing dust adhering to the fan 20. Rotation of the base 45 allows the brush bristles to oscillate between working and non-working positions. Furthermore, the brush 48 is typically made of durable material, capable of withstanding repeated use, making it suitable as a long-term cleaning tool.

[0102] It is understandable that cleaning component 40 could also be a sponge, felt, or other cleaning material.

[0103] Optionally, the base 45 is provided with a groove extending along the axial direction of the fan 20, and the bristles are disposed in the groove; when the cleaning component 40 includes a first cleaning section 43 and a second cleaning section 44, the first cleaning section 43 includes a first base 45, the first base 45 is provided with a first groove extending along the axial direction of the fan 20, the second cleaning section 44 includes a second base 45, the second base 45 is provided with a second groove extending along the axial direction of the fan 20, and the first groove and the second groove penetrate each other.

[0104] The first and second grooves are intersecting, allowing the bristles to be distributed along the axial direction of the fan 20, so that the cleaning area of ​​the brush 48 covers the entire axial surface of the fan 20, achieving a thorough cleaning without any dead corners.

[0105] Optionally, combined Figure 8 and Figure 11 As shown, the cleaning component 40 also includes reinforcing ribs 47, which surround the outer side of the base 45 and extend in a ring along the circumference of the base 45; when there are multiple reinforcing ribs 47, the multiple reinforcing ribs 47 are arranged at intervals along the axial direction of the fan 20.

[0106] A ring-shaped reinforcing rib 47 is provided on the outer side of the base 45 to form a ring support for the base 45, thereby improving the torsional and bending resistance of the base 45 and effectively improving the strength of the cleaning component 40. By arranging multiple reinforcing ribs 47 at intervals along the axial direction of the fan 20, uniform support can be provided to the base 45, reducing the deformation of the base 45 under stress, thereby improving the structural stability of the cleaning component 40.

[0107] Combination Figure 1-7 As shown, this disclosure provides an indoor unit for an air conditioner, including a housing 10, a fan 20, and a cleaning device 30 for the indoor unit as described in any of the above-disclosed embodiments. The housing 10 has an internal space 11; the fan 20 is disposed in the internal space 11; the cleaning component 40 is disposed in the internal space 11 and located beside the fan 20; and a support frame 50 is supported in the internal space 11.

[0108] The air conditioner indoor unit provided in this embodiment includes the cleaning device 30 for the air conditioner indoor unit as described in any of the above-described embodiments, and therefore has all the beneficial effects of the cleaning device 30 for the air conditioner indoor unit as described in any of the above-described embodiments, which will not be repeated here.

[0109] Optionally, combined Figure 2-6 As shown, the indoor unit of the air conditioner also includes a heat exchanger 60, which is located in the internal space 11, and a cleaning component 40 is located between the heat exchanger 60 and the fan 20.

[0110] Placing the cleaning component 40 between the heat exchanger 60 and the fan 20 avoids its direct impact on airflow performance. This also makes the cleaning component 40 less visible during operation, improving the cleanliness and aesthetics of the indoor unit. Furthermore, by positioning the cleaning component 40 between the heat exchanger 60 and the fan 20, the condensate on the surface of the heat exchanger 60 can capture and absorb dust generated during cleaning, reducing dust dispersion in the air duct and minimizing its impact on indoor air quality.

[0111] Optionally, combined Figure 2 and Figure 4 As shown, the indoor unit of the air conditioner also includes a water tray 70, which is located in the internal space 11. The water tray 70 is correspondingly arranged with the cleaning component 40 to collect the dust cleaned by the cleaning component 40.

[0112] The cleaning component 40 is used to clean dust that falls onto the fan 20. A water tray 70 is correspondingly positioned to collect dust that falls during the cleaning process. The water tray 70 can be located below the cleaning component 40 to effectively collect dust. Simultaneously, the water tray 70 can also effectively collect condensate generated by the heat exchanger 60 during the cooling process. Collecting dust through the water tray 70 prevents dust from flying around during cleaning, thereby improving airflow quality. The water tray 70 extends along the axial direction of the fan 20, corresponding to the extension direction of the cleaning component 40, enabling the water tray 70 to effectively collect dust.

[0113] Optionally, the indoor unit of the air conditioner also includes a controller configured to control the cleaning component 40 to move to the working position and to control the fan 20 to rotate in the forward or reverse direction.

[0114] When fan 20 needs cleaning, the controller moves the cleaning component 40 to the working position so that it contacts fan 20, and controls fan 20 to rotate. This effectively removes dust adhering to fan 20, improving cleaning efficiency. The controller can control fan 20 to rotate clockwise. This allows fan 20 to complete self-cleaning by using the same rotation direction as during normal airflow. Controlling fan 20 to rotate clockwise simplifies the self-cleaning control process, eliminating the need for additional structures and control logic to handle reverse rotation, making the entire cleaning process simpler. The controller can also control fan 20 to rotate counter-clockwise. In reverse rotation, due to centrifugal force, dust on fan 20 is more easily dislodged, improving cleaning efficiency.

[0115] Optionally, combined Figure 6 As shown, the cleaning device 30 also includes a drive member 31, which is driven to the cleaning member 40 to drive the cleaning member 40 to rotate between a working position and a non-working position; a controller is connected to the drive member to control the operation of the drive member.

[0116] The controller controls the drive unit to move the cleaning component 40, enabling the cleaning component 40 to automatically rotate between working and non-working positions, thus achieving automated cleaning of the fan 20. The drive unit can be a motor.
