[0003] Current air conditioner indoor units exchange indoor air through a fan system, with a filter installed in front of the fan to trap dust, lint, and other impurities in the air. However, over time, dirt accumulates on the filter surface. If not promptly removed, it can breed bacteria and even create odors, causing secondary indoor air pollution. Furthermore, it can reduce air intake, thereby impacting air conditioning performance.

[0004] At present, the filter is mainly cleaned in the following ways: using a dust suction device to absorb the dust on the filter; or using a brush to clean the dust on the filter; or using a driving mechanism to drive the filter and the brush or dust suction device to move simultaneously to clean the dust. For example, a filter dust removal mechanism is provided in the related art. The filter dust removal mechanism includes a winding device and an unfolding device for winding and unfolding the filter, respectively, wherein a dust removal part is provided on the winding device, and during the process of winding and / or unfolding the filter, the dust on the filter will be removed by the dust removal part. In this way, the automatic cleaning of the dust on the filter is achieved, the purification degree of the air outlet of the air conditioner is improved, and the air outlet quality of the air conditioner is improved.

[0005] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0006] To facilitate filter cleaning, the air conditioner indoor unit is equipped with a filter guide and dust removal mechanism. However, the filter is located between the air inlet and the heat exchanger. If the heat exchanger temperature is too high or too low, the filter guide mechanism may deform, resulting in guide failure. This can cause the filter to deform, affecting filter cleaning and even causing problems such as jamming and blocking of the filter stack.

[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0052] In conjunction with Figures 1, 2, 5, 14 and 16, an embodiment of the present disclosure provides a self-cleaning structure for an air conditioning filter, comprising a filter mounting frame 10, a rotating reel group, a filter 104 and a dust collecting device 40. The filter mounting frame 10 is constructed with a first reel mounting space 11 and a second reel mounting space 12 on opposite sides, with a keel frame 13 between the first reel mounting space 11 and the second reel mounting space 12; wherein the first reel mounting space 11 and / or the second reel mounting space 12 has an opening, and a support plate 14 is formed on the side of the opening; the rotating reel group comprises a first reel 20 and a second reel 30, the first reel 20 is rotatably disposed in the first reel mounting space 11, and the second reel 30 is rotatably disposed in the second reel mounting space 12; the filter The net is arranged on the first supporting surface 141 of the keel frame 13 and the support plate 14, and the first side is detachably connected to the first reel 20, and the second side is detachably connected to the second reel 30; wherein, the filter screen 104 is pre-wound on the first reel 20 or the second reel 30, and the pre-wound length is greater than or equal to the path distance of the filter screen 104 moving; the dust collecting device 40 is arranged on the first supporting surface 141 side of the support plate 14, and the dust collecting device 40 has a brush assembly 42 abutting against the filter screen, which is used to clean the filter screen 104 at the first supporting surface 141.

[0053] The self-cleaning structure of the air conditioning filter provided by the embodiment of the present disclosure comprises a curved keel frame 13 between the first reel mounting space 11 and the second reel mounting space 12. The first reel mounting space 11 and / or the second reel mounting space 12 have downwardly open sides formed with support plates 14. The first reel 20 is rotatably disposed within the first reel mounting space 11, and the second reel 12 is rotatably disposed within the second reel mounting space 12. Thus, during the movement of the filter 104, the curved keel frame 13 and support plates 14 can provide effective support for the entire surface of the filter 104, thereby preventing the sides of the filter from bending or deforming, allowing the filter to fully perform its filtering function. Furthermore, the filter 104 is pre-wound around the first reel 20 or the second reel 30, and the pre-wound length is greater than or equal to the path distance of the filter 104's movement. Thus, even when the filter is being cleaned, the pre-wound portion of the filter can still function as a filter. On this basis, a dust collecting device 40 is further provided below the first supporting surface 141 of the supporting plate 14. The filter screen 104 at the first supporting surface 141 is cleaned by the brush assembly 42, which enables the brush assembly 42 to fully contact the filter screen 104, thereby achieving a better cleaning effect.

[0054] In the disclosed embodiment, a first reel mounting space 11 and a second reel mounting space 12 are constructed on opposite sides of the filter mounting frame 10, with a curved keel frame 13 disposed between the first reel mounting space 11 and the second reel mounting space 12. Optionally, the first reel mounting space 11 has a downward opening, with support plates 14 formed on the sides of the opening. Optionally, the second reel mounting space 12 has a downward opening, with support plates 14 formed on the sides of the opening. Optionally, both the first reel mounting space 11 and the second reel mounting space 12 have downward openings, with support plates 14 formed on the sides of the opening.

[0055] Here, compared to a flat keel structure, the curved keel 13 and support plate 14 between the first and second reel mounting spaces 11, 12 can support the filter 104, ensuring that the filter 104 does not bend or deform, eliminating the need for a guide structure on the side. Furthermore, the movement of the filter 104 is not affected during cooling or heating.

[0056] In the disclosed embodiment, the first reel 20 can be used to deploy or reel the filter, and the second reel 30 can also be used to deploy or reel the filter. The filter is sufficiently long that it can filter regardless of whether deployed or reeled. Thus, the first reel 20 and the second reel 30 work together to deploy or reel the filter.

[0057] In the disclosed embodiment, the first reel 20 of the rotating reel assembly is rotatably mounted within the first reel mounting space 11, and the second reel 30 of the rotating reel assembly is rotatably mounted within the second reel mounting space 12. Furthermore, the first side of the filter 104 is detachably connected to the first reel 20, and the second side of the filter 104 is detachably connected to the second reel 30. The filter 104 can be wound around the reels, which ensures more uniform force on both sides of the filter, prevents localized deformation of the filter edges, and avoids problems such as filter stacking. Furthermore, the filter 104 is pre-wound around the first reel 20 or the second reel 30, with the pre-wound length being greater than or equal to the path of the filter 104's movement. Even when the filter is being cleaned, the pre-wound portion of the filter can still perform a filtering function. Furthermore, by wrapping the filter around the reels, the volume of the entire self-cleaning structure is reduced, thereby not obstructing the air inlet area, thereby increasing the air volume of the air conditioner and enhancing the cooling and heating performance.

[0058] In the disclosed embodiment, a dust collector 40 is disposed below the first support surface 141 of the support plate 14. The dust collector 40 includes a brush assembly 42 that abuts the filter. The first support surface 141 of the support plate 14 effectively supports the filter 104, preventing deformation. When cleaning the filter, the bristles of the brush assembly 42 abut against the filter, ensuring full contact with the filter 104 and enhancing cleaning effectiveness.

[0059] As shown in Figures 3 to 5, in some embodiments, the surface of the keel frame 13 that contacts the filter screen is a second supporting surface, and a sliding structure and / or rolling structure is provided on the second supporting surface. Since the filter screen is a flexible mesh structure, the keel frame 13 can provide effective support to the surface of the entire filter screen 10, preventing the filter screen from bending, deformation and other problems, thereby enabling the filter screen to fully play its filtering role. In addition, a sliding structure and / or rolling structure is provided on the second supporting surface of the keel frame 13, and the surface of the filter screen is in contact with the sliding structure and / or rolling structure. During the movement of the filter screen, the friction with the keel frame 13 can be reduced, which can not only reduce the noise generated by the movement of the filter screen, but also prevent problems such as filter screen damage.

[0060] In the disclosed embodiment, the filter mounting bracket 10 is positioned below the air inlet of the air conditioner and above the heat exchanger 100 to filter dust, impurities, and the like from the air inlet. The filter mounting bracket 10 comprises a frame 101 and an air conditioner connecting bracket 102. The frames 101 and 102 match in shape, with the connecting bracket 102 fixedly mounted above the heat exchanger 100 and the frame 101 removably mounted thereto.

[0061] In the embodiment of the present disclosure, the filter 104 is arranged above the keel frame 13. Here, in order to enable the keel frame 13 to provide effective support, the keel frame 13 is composed of a plurality of ribs with a large spacing between the plurality of ribs for air conditioning.

[0062] Alternatively, the keel frame 13 may be composed of a plurality of vertical ribs arranged in an array, wherein the vertical ribs are arranged perpendicular to the direction of movement of the filter screen. Alternatively, the keel frame 13 may be composed of a plurality of transverse ribs arranged in an array, wherein the transverse ribs are arranged parallel to the direction of movement of the filter screen. Alternatively, the keel frame 13 may be composed of a plurality of transverse ribs and vertical ribs arranged in an alternating manner. Alternatively, the keel frame 13 may be composed of a plurality of oblique ribs.

[0063] In conjunction with the above embodiments, regardless of the structure of the keel frame 13, a sliding structure and / or rolling structure is provided on the second support surface side of the keel frame 13, that is, a sliding structure and / or rolling structure is provided on the rib side, thereby effectively reducing the contact area between the filter screen and the keel frame 13. In this way, the resistance of the keel frame 13 to the filter screen can be reduced. At the same time, the noise generated by the movement of the filter screen can also be reduced. In addition, since the filter screen is a flexible mesh, it can also prevent the filter screen from being damaged by sliding contact with the sliding structure and / or rolling structure.

[0064] 3 to 5 , in some embodiments, the sliding structure 131 includes a plurality of arc-shaped protrusions provided on the keel frame 13 , so that the filter can slide smoothly on the keel frame 13 .

[0065] In the embodiment disclosed herein, a keel frame 13 is taken as an example, which is composed of a plurality of staggered transverse ribs and vertical ribs. Here, the transverse ribs serve to fix the plurality of vertical ribs together, ensure the stability of the entire keel frame 13, and prevent the vertical ribs from bending or breaking. Among them, the sliding structure 131 includes a plurality of arc-shaped protrusions, which are arranged on the vertical ribs, that is, the number of arc-shaped protrusions is the same as the number of vertical ribs. In addition, the length of the arc-shaped protrusions matches the length of the vertical ribs, and the cross-section of the arc-shaped protrusions is an arched structure. During the movement of the filter screen, the filter screen contacts the uppermost part of the arc-shaped protrusions, which greatly reduces the contact area compared to the contact with the ribs, thereby not only playing a supporting role, but also enabling the filter screen to slide smoothly on the keel frame 13, avoiding the filter screen stack from being stuck on the frame 101.

[0066] In some embodiments, the rolling structure includes a plurality of rotating rollers disposed on the keel frame 13 , so that the filter can move smoothly on the keel frame 13 .

[0067] In the embodiment disclosed herein, the keel frame 13 is taken as an example and is composed of a plurality of staggered transverse ribs and vertical ribs. Among them, the sliding structure 131 includes a plurality of rotating rollers (not shown in the figure), which are arranged on the vertical ribs, and the number of the rotating rollers is the same as the number of the vertical ribs. The rotating roller includes a through groove opened on the vertical rib, and the shaft of the roller rotates in the through groove. In this way, during the movement of the filter screen, sliding friction can be converted into rolling friction, further reducing the resistance to the filter screen, so that the filter screen can move smoothly on the keel frame 13, and avoid being stuck on the frame 101.

[0068] 4 and 5 , in some embodiments, the cross-section of the keel frame 13 is a curved structure, which ensures that the filter screen is always in contact with the keel frame 13 and the filter screen is fully expanded.

[0069] In the embodiment of the present disclosure, since the filter is a flexible mesh, it is easy to wrinkle and deform in the absence of supporting force. Therefore, the filter can be stretched straight by the force at both ends. Here, there is a height difference between the first reel installation space 11 and the second reel installation space 12, and the keel frame 13 provided between the first reel installation space 11 and the second reel installation space 12 has a curvature, so that the keel frame 13 forms an arch. In this way, the filter can be stretched straight by the first reel 20 and the second reel 30, and the keel frame 13 can support the filter so that the filter is always in contact with the keel frame 13.

[0070] 6 , in some embodiments, a side connection portion 103 detachably connected to the air conditioner connection frame 102 is provided on the side frame of the frame body 101. A corresponding matching structure is provided on the air conditioner connection frame 102 for detachably connecting to the side connection portion 103.

[0071] As shown in FIG. 6 , in some embodiments, the side connection portion 103 includes a fixing structure 1031 , which is disposed in the middle of the side frame of the frame 101 and is used to connect and fix the air conditioner connecting frame 102 to the frame 101 .

[0072] In the embodiment of the present disclosure, a fixing structure 1031 is provided in the middle of the side frame of the frame 101, and correspondingly, a corresponding fixing matching structure is provided on the air-conditioning connecting frame 102. In this way, the fixing structure 1031 and the fixing matching structure can fix the frame 101 on the air-conditioning connecting frame 102. Here, one of the fixing structure 1031 and the fixing matching structure is a buckle, and the other of the fixing structure 1031 and the fixing matching structure is a slot. Specifically, in the case where the fixing structure 1031 is a buckle, the fixing matching structure is a slot; in the case where the fixing structure 1031 is a slot, the fixing matching structure is a buckle. In this way, the buckle and the slot are mutually engaged to connect and fix the frame 101 to the air-conditioning connecting frame 102.

[0073] As shown in FIG6 , in some embodiments, the side connection portion 103 further includes a positioning structure 1032 , which is provided at both ends of the side frames of the frame 101 and is used to position the air conditioner connecting frame 102 and the frame 101 .

[0074] In the embodiment of the present disclosure, a positioning structure 1032 is provided in the middle of the side frame of the frame 101, and correspondingly, a corresponding positioning and matching structure is provided on the air-conditioning connecting frame 102. Here, the side frame of the frame 101 is provided with a fixing structure 1031 and a positioning structure 1032, and the air-conditioning connecting frame 102 is provided with a fixing and matching structure and a positioning and matching structure, and the fixing structure 1031 and the fixing and matching structure are engaged in the engagement position in the orientation direction of the positioning structure 1032 and the positioning and matching structure. Among them, the fixing structure 1031 and the fixing and matching structure are used to ensure the connection stability between the frame 101 and the air-conditioning connecting frame 102; the positioning structure 1032 and the positioning and matching structure are used to ensure the connection accuracy between the frame 101 and the air-conditioning connecting frame 102. In this way, the connection and fixation between the frame 101 and the air-conditioning connecting frame 102 are facilitated.

[0075] Optionally, one of the positioning structure 1032 and the positioning matching structure is a positioning guide rail, and the other of the positioning structure 1032 and the positioning matching structure is a positioning slot. Specifically, when the positioning structure 1032 is a positioning guide rail, the positioning matching structure is a positioning slot; when the positioning structure 1032 is a positioning slot, the positioning matching structure is a positioning guide rail.

[0076] As shown in Figure 7, in some embodiments, the first reel 20 is provided with a first mounting structure 21 along its axial surface, and the first side of the filter is detachably connected to the first mounting structure 21; the second reel 30 is provided with a second mounting structure 31 along its axial surface, and the second side of the filter is detachably connected to the second mounting structure 31.

[0077] In the embodiment of the present disclosure, both reels of the rotating reel assembly are used to install the filter screen, so that the first reel 20 and the second reel 30 can form a rotating structure. Among them, the first reel 20 and the second reel 30 are both round rod structures. In this way, when the filter screen is installed on the first reel 20 and the second reel 30, the filter screen can be moved in a variety of ways. Optionally, the second reel 30 is driven to rotate by the active rotation of the first reel 20. Optionally, the first reel 20 is driven to rotate by the active rotation of the second reel 30. Optionally, the first reel 20 and the second reel 30 are driven to rotate by synchronization.

[0078] Because the filter is pre-wound around the first or second reel 20, 30, and the pre-wound length is greater than or equal to the path the filter travels, to prevent the filter mounting bracket 10 from obstructing the movement of the filter 104, in some embodiments, a predetermined distance is provided between the circumferential surface of the first reel 20 and the inner wall of the first reel mounting space 11; and a predetermined distance is provided between the circumferential surface of the second reel 30 and the inner wall of the second reel mounting space 12. This ensures that the filter on the first or second reel 20, 30, does not come into contact with the first or second reel mounting space 11, 12, thereby allowing the filter to move smoothly.

[0079] Optionally, as shown in FIG5 , the first reel installation space 11 and the second reel installation space 12 are both arc-shaped trough structures. Since the first reel 20 and the second reel 30 are both round rod structures, the installation form of the first reel 20 in the first reel installation space 11 is the same as the installation form of the second reel 30 in the second reel installation space 12. Here, taking the installation of the first reel 20 in the first reel installation space 11 as an example, the two ends of the first reel 20 are respectively connected to the two ends of the arc-shaped trough, and there is a specific set distance between the outer surface of the first reel 20 and the inner wall of the arc-shaped trough. The path distance of the set distance must at least meet the thickness of the stacked filter after the filter is pre-wound. In this way, it can be ensured that the filter on the first reel 20 or the second reel 30 will not contact the first reel installation space 11 or the second reel installation space 12, so that the filter can move smoothly.

[0080] As shown in Figures 7 and 8, in the embodiment of the present disclosure, taking the active rotation of the second reel 30 driving the passive rotation of the first reel 20 as an example, the first side edge of the filter screen is mounted on the first mounting structure 21, and the filter screen is partially pre-wound along the outer circumference of the first reel 20. Optionally, the first mounting structure 21 includes a first strip groove 211 provided on the surface of the first reel 20 and a first clamping strip 212 provided in the first strip groove 211, and the first side edge of the filter screen is clamped in the first strip groove 211 by the first clamping strip 212. Optionally, the first mounting structure 21 includes a bonding portion, and the first side edge of the filter screen can also be directly fixed to the axial surface of the first reel 20 by bonding.

[0081] In the disclosed embodiment, the first strip groove 211 is a through groove extending along the axial surface of the first reel 20. The length of the first clamping bar 212 matches the length of the first strip groove 211. To install the filter, first place the side of the filter into the first strip groove 211, then insert the first clamping bar 212 into the first strip groove 211. This secures the filter in place within the first strip groove 211. To remove the filter, simply remove the first clamping bar 212 from the first strip groove 211.

[0082] As shown in Figures 7 and 8 , in the disclosed embodiment, a second mounting structure 31 is provided on the axial surface of the second reel 30. Optionally, the second mounting structure 31 includes a second strip groove 311 provided on the surface of the second reel 30 and a second clamping strip 312 provided within the second strip groove 311. The second side edge of the filter screen is clamped within the second strip groove 311 by the second clamping strip 312. Optionally, the second mounting structure 31 includes an adhesive portion, and the second side edge of the filter screen can also be directly fixed to the axial surface of the second reel 30 by adhesive bonding. Here, the form in which the filter screen is mounted on the second mounting structure 31 is the same as the form in which the filter screen is mounted on the first mounting structure 21, and will not be repeated here.

[0083] In the above embodiment, one side of the filter screen is fixed by clamping, and the other side can also be fixed by bonding.

[0084] As shown in Figures 7 and 8, in some embodiments, the first reel 20 includes: a first shaft rod 22, at least partially a hollow through cavity in the axial middle portion thereof; a first sleeve 23, one end of which is plugged and fixed to the first end of the first shaft rod 22, and the other end is rotatably connected to the first end of the first reel installation space 11; an elastic reset assembly 24, one end of which is plugged and fixed to the second end of the first shaft rod 22, and the other end is fixedly connected to the second end of the first reel installation space 11.

[0085] In the disclosed embodiment, at least a portion of the axially central portion of the first shaft 22 is hollow, allowing the elastic return assembly 24 to extend therethrough. A first strip-shaped groove 211 is defined on the surface of the first shaft 22. Both ends of the first strip-shaped groove 211 are sealed by a first sleeve 23 and an elastic return assembly 24.

[0086] In the embodiment disclosed herein, the first scroll 20 is driven to rotate, and the second scroll 30 is actively rotated. The first scroll 20 includes a first shaft 22 and a first sleeve 23 and an elastic reset assembly 24 provided at both ends. The first sleeve 23 is rotatably connected to the first end of the first scroll installation space 11 for the rotation of the first shaft 22. The elastic reset assembly 24 is fixedly connected to the second end of the first scroll installation space 11 for the reset rotation of the first shaft 22. For example, when the second scroll 30 rotates, the filter screen will move accordingly, and the first scroll 20 will also rotate accordingly. After the filter screen is cleaned, the second scroll 30 rotates in the opposite direction. At this time, the first scroll 20 is reset through the elastic reset assembly 24, so that the filter screen can return to its original position.

[0087] In the above embodiment, the first reel 20 reels the filter screen through the elastic return assembly 24 , and the second reel 30 unfolds the filter screen.

[0088] In combination with Figures 9 and 10, in order to facilitate the elastic reset assembly 24 to perform the filter reeling action, in some embodiments, the elastic reset assembly 24 includes: a connecting seat 241, which is inserted into the second end of the first shaft 22, and a socket 242 is provided in the middle of the connecting seat 241; a pin shaft 243, one end of which extends into the hollow cavity of the first shaft rod 22 through the socket 242, and the other end is used to be fixedly connected to the second end of the first reel installation space 11; a torsion spring 244, which is sleeved on the pin shaft 243, and one end is fixedly connected to the connecting seat 241, and the other end is fixedly connected to the end of the pin shaft 243 located in the hollow cavity.

[0089] In the disclosed embodiment, the elastic reset assembly 24 includes a connecting seat 241, a pin 243, and a torsion spring 244. Because the axial center portion of the first shaft 22 is a hollow cavity, after the connecting seat 241 is inserted and fixed, the pin 243 can extend into the hollow cavity through the insertion hole 242, and the torsion spring 244 is sleeved on the pin 243. One end of the torsion spring 244 is fixedly connected to the connecting seat 241, and the other end of the torsion spring 244 is fixedly connected to the end of the pin 243 located in the hollow cavity.

[0090] When the second reel 30 drives the first reel 20 to rotate, the first shaft 22 drives the connecting seat 241 in the elastic reset assembly 24 to rotate, so that the connecting seat 241 rotates on the pin 243. Since one end of the torsion spring 244 is fixedly connected to the connecting seat 241 and the other end of the torsion spring 244 is fixedly connected to the pin 243, the connecting seat 241 and the pin 243 rotate relative to each other, so that the torsion spring 244 is twisted and elastically deformed to generate elastic force; when the second reel 30 rotates in the opposite direction, the elastic force of the torsion spring 244 forces the first shaft 22 to return to its original position.

[0091] As shown in Figure 10, in some embodiments, the axial length of the pin 243 is greater than the axial length of the torsion spring 244, wherein a fixing groove 247 is provided at the end of the pin 243 located in the hollow cavity, and the other end of the torsion spring 244 is fixedly connected to the fixing groove 247.

[0092] In the embodiment of the present disclosure, the length of the torsion spring 244 or the spacing between the coils of the torsion spring 244 can be changed according to the torque or rotational force required by the first shaft 22. Here, the first end of the torsion spring 244 is fixed to the connecting seat 241, and the second end of the torsion spring 244 is fixed to the pin 243. A fixing groove 247 is provided at the end of the pin 243, and the axial end of the torsion spring 244 is inserted and fixed in the fixing groove 247. For example, the end of the torsion spring 244 is a steel wire, and the steel wire is fixedly inserted in the fixing groove 247. When the first shaft 22 rotates in the opposite direction around the center of the torsion spring 244, the two ends of the torsion spring 244 will generate torque or rotational force.

[0093] As shown in Figure 10, in some embodiments, the pin shaft 243 is provided with a connecting slot 245 on the side of the connecting seat 241, and the elastic reset assembly 24 also includes: a fixing plate 246, one end of which is inserted into the connecting slot 245, and the other end is fixedly connected to the second end of the first reel installation space 11.

[0094] In the disclosed embodiment, to facilitate the securing of the pin 243, a square connection notch 245 is provided on the pin 243. This prevents the fixing plate 246 from rotating with the pin 243 when the fixing plate 246 is inserted into the connection notch 245. The fixing plate 246 is located on one side of the second end of the first reel mounting space 11 and is provided with a fixing hole. The fixing plate 246 is secured to the second end of the first reel mounting space 11 by screws passing through the fixing hole.

[0095] As shown in Figures 7 and 8, in some embodiments, the second reel 30 includes: a second shaft 32; a transmission member 33, one end of which is plugged and fixed to the first end of the second shaft 32, and the other end is connected to the driving end of the second reel installation space 12; a second sleeve 34, one end of which is plugged and fixed to the second end of the second shaft 32, and the other end is rotatably connected to the rotating end of the second reel installation space 12.

[0096] In the disclosed embodiment, the second shaft 32 is a solid rod, and a second strip groove 311 is formed on the surface of the second shaft 32. The ends of the second strip groove 311 are sealed by a second sleeve 34 and a transmission member 33. Furthermore, the second sleeve 34 and the transmission member 33 can be fixed to the ends of the second shaft 32 by screws.

[0097] In the disclosed embodiment, the second reel 30 is actively rotated. The second reel 30 includes a second shaft 32, a second sleeve 34 disposed at both ends, and a transmission member 33. The second sleeve 34 is rotatably connected to the rotating end of the second reel mounting space 12 for rotating the second shaft 32. The transmission member 33 is connected to the drive end of the second reel mounting space 12 for actively rotating the second shaft 32. Optionally, a drive motor is disposed on the drive end side of the second reel mounting space 12, and the drive motor is connected to the transmission member 33.

[0098] In the above embodiment, the first sleeve 23 and the second sleeve 34 are both made of self-lubricating material, which can reduce the friction between each reel and the connecting portion.

[0099] As shown in conjunction with Figures 11 to 14, in some embodiments, the dust collection device 40 includes: a dust box 41 disposed below a first support surface 141 of the support plate 14, the dust box 41 having an opening facing the first support surface 141; a brush assembly 42 disposed within the dust box 41, below the opening, with bristles of the brush assembly 42 protruding from the opening; and a support plate 14 disposed at the opening of the dust box 41, through which a filter passes, to provide effective support for the filter and prevent deformation of the filter. The brush assembly 42 is disposed within the dust box 41, and the bristles of the brush assembly 42 abut against the filter. Thus, when cleaning the filter, the first support surface 141 can provide effective support for the filter, preventing excessive deformation caused by contact with the bristles of the brush assembly 42. This allows the bristles of the brush assembly 42 to fully contact the filter, facilitating the removal of dust and impurities from the filter, thereby improving the cleaning efficiency of the dust removal structure.

[0100] 14 , in some embodiments, the first support surface 141 of the support plate 14 is a dome structure or a plane structure, wherein the first support surface 141 of the support plate 14 is further provided with a support protrusion 142 to support the filter passing through the first support surface 141 .

[0101] In the embodiment of the present disclosure, since the first support surface 141 of the support plate 14 can support the filter screen, the first support surface 141 is an arched surface structure or a plane structure. Here, the arched surface structure refers to the support plate 14 being an arc-shaped plate, and the plane structure refers to the support plate 14 being a flat plate. The filter screen abuts against the first support surface 141, and at the same time, the bristles of the brush assembly 42 also abut against the filter screen, so that the first support surface 141 can ensure that the brush assembly 42 does not deform the filter screen. On this basis, a support protrusion 142 is also provided on the first support surface 141, and the support protrusion 142 has a certain height on the first support surface 141. Therefore, the filter screen at this position is separated from the first support surface 141. In this way, the bristles of the brush assembly 42 can pass through the filter holes of the filter screen to further clean the filter screen.

[0102] As shown in FIG14 , in some embodiments, the first support surface 141 is further provided with an escape groove 143 located on the side of the movement path of the brush assembly 42. The bristles of the brush assembly 42 can enter the escape groove 143 when passing through the filter. This not only ensures that the bristles of the brush assembly 42 are in full contact with the filter, but also reduces the force on the brush assembly 42, preventing the bristles of the brush assembly 42 from being squeezed by the first support surface 141 for a long time, which could cause the bristles of the brush assembly 42 to bend.

[0103] In some embodiments, the side edges of the first support surface 141 of the support plate 14 are curved. This prevents the side edges of the support plate 14 from scratching the filter screen. Here, the filter screen passes through the entire first support surface 141, but the filter screen is wound around the support plate 14, meaning that the filter screen can abut against the side edges of the first support surface 141. To prevent the support plate 14 from scratching the filter screen, the edges of the first support surface 141 are rounded. This not only reduces the resistance of the side edges to the filter screen, but also prevents the side edges of the support plate 14 from scratching the filter screen.

[0104] As shown in Figures 14 and 15, in some embodiments, the dust collecting device 40 further includes: a cleaning structure 43, which is arranged in the dust box 41 and / or at the opening of the dust box 41, for cleaning the bristles in the brush assembly 42.

[0105] In the embodiment of the present disclosure, during the process of the brush assembly 42 cleaning the dust from the filter, the dust from the filter can be cleaned. However, there will inevitably be residual dust and impurities on the bristles of the brush assembly 42. After long-term use, the cleaning effect will deteriorate or even lose the cleaning ability. Therefore, the dust on the bristles of the brush assembly 42 is cleaned by the cleaning structure 43 to improve the cleaning effect. Optionally, a cleaning structure 43 can be provided in the dust box 41. Optionally, a cleaning structure 43 can be provided at the opening of the dust box 41. Optionally, a cleaning structure 43 can be provided both in the dust box 41 and at the opening of the dust box 41.

[0106] As shown in Figures 14 and 15, in some embodiments, the cleaning structure 43 includes: a first cleaning part 431, which is arranged in the dust box 41 and is located below the first support surface 141 of the support plate 14. The first cleaning part 431 has a first cleaning edge that abuts against the bristles of the brush assembly 42.

[0107] In the disclosed embodiment, the first cleaning portion 431 is positioned opposite the support plate 14, and the distance between the first cleaning portion 431 and the first support surface 141 is smaller than the diameter of the brush assembly 42. Therefore, during rotation, the brush assembly 42 abuts not only against the filter but also against the first cleaning edge of the first cleaning portion 431. This allows the brush assembly 42 to clean dust from the filter, and then the first cleaning edge of the first cleaning portion 431 sweeps away any remaining dust.

[0108] Optionally, as shown in FIG15 , the first cleaning portion 431 includes one or more vertical plates 4311 arranged in series, wherein the vertical surface of each vertical plate 4311 forms an angle with the axis of the brush assembly 42, and each vertical plate 4311 has a serrated structure on the side facing the brush assembly 42, and multiple serrated structures constitute the first cleaning edge. To achieve a better cleaning effect, multiple vertical plates 4311 are arranged at an angle at the bottom of the dust collection box 41, and a serrated structure is provided on the vertical plates 4311, which is also arranged at an angle. This allows the serrated structure to be arranged more densely, thereby cleaning more thoroughly.

[0109] As shown in Figures 14 and 15, in some embodiments, the cleaning structure 43 also includes: a second cleaning part 432, which is arranged on the open side of the dust box 41 and is located on the side of the support plate 14. The second cleaning part 432 has a second cleaning edge that abuts against the bristles of the brush assembly 42.

[0110] In the disclosed embodiment, during the rotation of the brush assembly 42, the brush assembly 42 first cleans the filter screen on the first support surface 141. The brush assembly 42 then passes through the second cleaning portion 432, which performs a rough cleaning on the brush assembly 42 to remove larger dust particles on the brush assembly 42. The brush assembly 42 then passes through the first cleaning portion 431, which performs a fine cleaning on the brush assembly 42 to remove the remaining fine dust particles on the brush assembly 42. In this way, the brush assembly 42, after being cleaned by the second cleaning portion 432 and the first cleaning portion 431, can remove most of the dust and impurities in the brush assembly 42, ensuring that the clean brush assembly 42 cleans the filter screen.

[0111] Optionally, the second cleaning portion 432 includes an extended edge 4321 extending from the opening of the dust box 41 toward the support plate 14. The side edges of the extended edge 4321 are serrated, and the continuous serrated structure constitutes the second cleaning edge. The extended edge 4321 faces the support plate 14 and curves toward the bottom of the dust box 41. This ensures that dust and impurities from the brush assembly 42 enter the dust box 41 and avoid falling outside the dust box 41.

[0112] In some embodiments, the inner wall of the dust box 41 is affixed with a sticker or coating of antibacterial material. In this way, it is convenient to clean the dust collected in the dust box 41, and it is also possible to prevent the dust in the dust box 41 from generating bacteria and flowing into the room.

[0113] In the embodiment of the present disclosure, the antibacterial material includes inorganic antibacterial agents, organic (synthetic) antibacterial agents, natural organic antibacterial agents, polymer antibacterial agents or composite antibacterial agents, etc., and a sticker is made by using one or more of the above antibacterial agents, and the sticker is applied to the inner wall of the dust box 41.

[0114] In the embodiment of the present disclosure, one or more antibacterial agents mentioned above may be used to make a coating, and the coating may be applied to the inner wall of the dust box 41 .

[0115] Optionally, a corresponding sensor may be provided in the dust box 41 , and when it is detected that the dust in the dust box 41 has reached a set threshold, the dust box 41 is cleaned.

[0116] As shown in Figures 16 and 17, in some embodiments, the self-cleaning structure for the air conditioning filter also includes: a driving device 50, which is arranged on the side of the filter mounting frame 10 and drives the second reel 30 and the brush assembly 42 to rotate synchronously through the transmission gear set 60.

[0117] In the disclosed embodiment, the second reel 30 is actively rotated. A drive device 50 is disposed adjacent to the second reel 30. This drive device 50 can utilize a drive motor capable of both forward and reverse rotation. Thus, when the filter needs to be cleaned, the drive motor rotates forward, unrolling the filter via the second reel 30. After the filter is cleaned, the drive motor rotates reversely, rewinding the filter via the first and second reels 20 and 30. Here, the drive device 50 drives the second reel 30 and the brush assembly 42 to rotate synchronously via a transmission gear set 60. This ensures that the brush assembly 42 can clean the filter as long as the filter is moving.

[0118] As shown in Figure 18, in some embodiments, the transmission gear set 60 includes: a first gear 61, which is arranged on the side of the second reel installation space 12 and is connected to the end of the second reel 30; a second gear 62, which is arranged on the side of the dust collecting device 40 and is connected to the end of the brush assembly 42; the second gear 62 is arranged close to the first gear 61 and the second gear 62, and is respectively engaged with the first gear 61 and the second gear 62; a fourth gear 64, which is arranged on the side of the filter mounting frame 10 and is engaged with the third gear 63; wherein the fourth gear 64 is connected to the driving end of the driving device 50.

[0119] In the disclosed embodiment, to enable synchronous rotation of the second reel 30 and the brush assembly 42, the transmission gear set 60 comprises multiple gears, including a first gear 61, a second gear 62, a third gear 63, and a fourth gear 64. The first gear 61 and the second gear 62 serve as direct gears between the second reel 30 and the brush assembly 42, the third gear 63 is a synchronous transmission gear, and the fourth gear 64 is a drive gear. By meshing and rotating the fourth gear 64 with the third gear 63, the third gear 63 simultaneously drives the first gear 61 and the second gear 62 to rotate, thereby achieving synchronous rotation of the second reel 30 and the brush assembly 42.

[0120] In some embodiments, the diameters of the first gear 61, the second gear 62, and the fourth gear 64 are all smaller than the diameter of the third gear 63. This allows the drive device 50 to more conveniently control the rotation angles of the first gear 61 and the second gear 62 via the third gear 63, thereby controlling the movement speed of the filter. Furthermore, the drive device 50 can be installed in a variety of locations, eliminating the need for it to be fixed in a specific location, which could affect the use of other components. For example, if the drive device 50 is installed on the side of the dust collector 40, it may hinder the user's ability to clean dust.

[0121] In the embodiment of the present disclosure, in order for the driving device 50 to drive the filter to move through the transmission gear set 60, the power torque and resistance torque on the gear transmission side should meet the following conditions: M1*Z2 / Z1>M n *Z2 / Z4+M b *Z2 / Z3

[0122] Wherein, M1 is the torque of the driving device 50, M n is the drag torque of the reel, M b is the resistance torque of the brush assembly 42 , Z1 is the diameter of the fourth gear 64 , Z2 is the diameter of the third gear 63 , Z3 is the diameter of the second gear 62 , and Z4 is the diameter of the first gear 61 .

[0123] In the disclosed embodiment, the resistance torque on the reel side should satisfy the following conditions: M n =R4*F n

[0124] Wherein, R4 is the radius of the second scroll 30, F n is the resistance torque of the second reel 30 .

[0125] In the embodiment of the present disclosure, the resistance torque of the second reel 30 should satisfy the following conditions: F n ={K*S / (R5*R5)+f2+f3}

[0126] Wherein, K is the stiffness of the torsion spring 244 , S is the distance the filter moves, R5 is the radius of the first reel 20 , f2 is the resistance between the filter 104 and the brush assembly 42 , and f3 is the resistance between the filter 104 and the filter mounting bracket 10 .

[0127] In the embodiment of the present disclosure, the resistance torque of the brush assembly 42 should meet the following conditions: b =R3*f2

[0128] Wherein, R3 is the radius of the brush assembly 42 .

[0129] In conjunction with the above embodiment, the ratio of the power torque to the resistance torque on the gear transmission side is in the range of [1.1, 1.9], that is, the power torque is greater than the resistance torque. Optionally, the ratio of the power torque to the resistance torque is in the range of [1.2, 1.8]. Optionally, the ratio of the power torque to the resistance torque is in the range of [1.3, 1.7]. Optionally, the ratio of the power torque to the resistance torque is in the range of [1.4, 1.6]. Optionally, the range of the set angle is 1.5.

[0130] In a specific application, the ratio of the dynamic torque to the resistance torque is 1.5. Of course, in other applications, the ratio of the dynamic torque to the resistance torque can be selected from any ratio within the range of [1.1, 1.9] and can be set according to actual needs.

[0131] In the above embodiment, since the filter screen is very thin and the number of winding layers of the filter screen on the first reel 20 and the second reel 20 is limited, the change in the total diameter of the two reels during the winding process of the filter screen is ignored.

[0132] The disclosed embodiment also provides an air conditioner, comprising: an air conditioner body having an air inlet; a self-cleaning structure for an air conditioner filter as described in the aforementioned embodiment, wherein a filter mounting frame 10 of the self-cleaning structure is arranged below the air inlet, and a filter is arranged on the filter mounting frame 10.

[0133] With reference to the above embodiment, the air conditioner includes the above self-cleaning structure for the air conditioning filter. With reference to the above embodiment, it at least has the beneficial effects brought by the technical solutions of the above embodiment, which will not be described one by one here.

[0134] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof.
