Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a filter self-cleaning device for an air conditioner and an air conditioner. Background Technology

[0002] Currently, air conditioners continuously draw in indoor air during operation and filter it through a filter. During this process, tiny particles such as dust, hair, and dander are trapped by the filter and accumulate there. If the filter is not cleaned for a long time, these particles will build up, forming a layer of grime. This not only reduces the filter's filtration performance but may also cause the accumulated particles to be blown back into the room during air conditioning operation, leading to decreased indoor air quality and respiratory discomfort.

[0003] To achieve automatic dust removal from the filter screen, a related technology discloses an indoor air conditioning unit. The indoor unit includes a housing with an air inlet and an air outlet, a filter screen for filtering air at the air inlet, and a cleaning device for automatically cleaning dust from the filter screen. The cleaning device is located below the filter screen and can clean and collect dust from it. The cleaning device includes a brush and a dust collection box. The brush contacts the lower surface of the filter screen, and the dust collection box is located below the brush. When cleaning the filter screen is required, the filter screen moves in a circular motion driven by a drive shaft. The brush gradually contacts different parts of the filter screen, thereby brushing off the dust from the entire filter screen. The dust falls into the dust collection box, thus achieving automatic cleaning of the filter screen.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: In related technologies, the dust collection box is slidably engaged with a guide rail and a groove on a guide box to achieve pull-out loading and unloading. While this sliding engagement method can complete the disassembly and cleaning of the dust collection box, the friction during the sliding process is relatively large, which may result in less smooth pulling, especially when there is a lot of dust inside the dust collection box and the weight increases, requiring the user to apply more force.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0032] Combination Figure 1-10 As shown, this disclosure provides a filter self-cleaning device for an air conditioner, including a filter 10, a cleaning component 20, a dust collection funnel 30, and a dust collection box 40.

[0033] The filter screen 10 is suitable for installation at the air inlet 61 of the air conditioner; the cleaning component 20 is correspondingly arranged with the filter screen 10 and can contact the filter screen 10 to clean it; the dust collection funnel 30 is located below the cleaning component 20 and has a dust guiding cavity 31 with an inlet 311 and an outlet 312. The inlet 311 corresponds to the contact position between the cleaning component 20 and the filter screen 10 and is used to guide the dust collected during cleaning downward into the dust guiding cavity 31; the dust collection box 40 is located below the dust collection funnel 30 and has a dust collection box 40. A storage space with an opening 41 is provided, which corresponds to the outlet 312 of the dust collection funnel 30 and is used to receive dust in the dust guiding chamber 31. The dust collection box 40 is detachably connected to the dust collection funnel 30. The dust collection funnel 30 is provided with a rolling part 32, and the dust collection box 40 is provided with a rolling engagement part 42 adapted to the rolling part 32. During the process of disassembling or installing the dust collection box 40 relative to the dust collection funnel 30, the rolling part 32 and the rolling engagement part 42 roll in engagement.

[0034] The air conditioner filter self-cleaning device provided in this embodiment maintains a rolling engagement between the rolling part 32 of the dust collection funnel 30 and the rolling mating part 42 of the dust collection box 40 during disassembly and installation. This rolling friction significantly reduces the force required to operate the dust collection box 40, improving the ease of installation and removal. Simultaneously, the rolling engagement structure formed by the rolling part 32 and the rolling mating part 42 also reduces contact wear between components, extending the service life of the dust collection box 40 and the dust collection funnel 30.

[0035] In addition, the filter 10 is located at the air inlet 61 of the air conditioner, which can effectively intercept dust in the incoming airflow and prevent pollutants from entering the air duct. The cleaning component 20 contacts the filter 10 and can effectively clean the dust attached to the filter 10, preventing the filter 10 from becoming clogged and reducing its filtration performance. The dust collection funnel 30 is located below the cleaning component 20. The inlet 311 of the dust guiding chamber 31 of the dust collection funnel 30 corresponds to the contact position between the cleaning component 20 and the filter 10, which can guide the cleaned dust to fall steadily along the dust guiding chamber 31 and prevent the dust from scattering during the fall. The dust collection box 40 is located below the dust collection funnel 30. The opening 41 of the storage space of the dust collection box 40 corresponds to the outlet 312 of the dust guiding chamber 31. After the dust cleaned by the cleaning component 20 from the filter 10 is guided down by the dust guiding chamber 31, it can fall completely into the storage space of the dust collection box 40, preventing the dust from spreading again. Furthermore, the dust collection box 40 and the dust collection funnel 30 are detachably connected. When the dust in the dust collection box 40 accumulates to a preset amount, the dust collection box 40 can be disassembled from below the dust collection funnel 30 to clean the dust in the box. After cleaning, the dust collection box 40 can be reinstalled in its original position, which can realize convenient dust disposal and improve the convenience of maintenance.

[0036] The cleaning component 20 can be a brush, a sponge, or other cleaning structure. The cleaning component 20 extends along the width of the filter screen, and the inlet 311 of the dust collection funnel also extends accordingly along the width of the filter screen. When the filter screen moves along its length, the cleaning component can clean the entire width area of ​​the filter screen, improving the cleaning effect.

[0037] Optionally, combined Figure 2 and Figure 3 As shown, one of the rolling part 32 and the rolling mating part 42 is a roller 321, and the other is a guide rail 422. The guide rail 422 extends along a first direction, and the roller 321 is adapted to the guide rail 422. When the dust collection box 40 is disassembled or installed relative to the dust collection funnel 30, the roller 321 rolls along the guide rail 422 to guide the movement of the dust collection box 40. The first direction is the front-back direction or the up-down direction of the air conditioner.

[0038] Forward and backward directions, such as Figure 10 As indicated by the middle arrow, the up and down directions are as follows: Figure 9 The direction indicated by the middle arrow.

[0039] The rolling engagement structure between roller 321 and guide rail 422 is stable. When the dust collection box 40 is pulled out or driven to move relative to the dust collection funnel 30, roller 321 will strictly roll along guide rail 422, preventing the dust collection box 40 from shifting left or right or getting stuck during movement, thus ensuring that the dust collection box 40 can be loaded and unloaded stably and smoothly. Alternatively, the rolling part 32 can be roller 321, located in the dust collection funnel 30, and the rolling engagement part 42 can be guide rail 422, located in the dust collection box 40. Or, the rolling part 32 can be guide rail 422, located in the dust collection funnel 30, and the rolling engagement part 42 can be roller 321, located in the dust collection box 40. This application uses roller 321 as the rolling part 32 and guide rail 422 as the rolling engagement part 42 as an example.

[0040] Taking a wall-mounted air conditioner as an example, the air conditioner includes a housing 60, which comprises a front panel 64, a rear panel, a top panel, a bottom panel 65, and two side panels, collectively enclosing the internal installation space and the external appearance. When the air conditioner is installed and in normal use, the rear panel is the panel of the housing 60 facing the mounting carrier (such as a wall), the front panel 64 is the panel of the housing 60 facing away from the mounting carrier and towards the user's activity area, the top panel is the panel of the housing 60 located at the top along the direction of gravity (i.e., vertically), and the bottom panel 65 is the panel of the housing 60 located at the bottom along the direction of gravity (i.e., vertically). Figure 10 As shown, "front" refers to the direction from the front panel 64 towards the user. "Rear" refers to the direction from the rear panel towards the mounting medium (such as a wall). Figure 9 As shown, "above" refers to the direction from the bottom plate 65 towards the top plate. "Below" refers to the direction from the top plate towards the bottom plate 65.

[0041] When the guide rail 422 extends along the front-to-back direction of the air conditioner, the guide rail 422, in conjunction with the matching roller 321, guides the dust collection box 40 to move relative to the dust collection funnel 30 in the front-to-back direction. To remove the dust collection box 40, pull or drive it forward; the roller 321 rolls forward along the guide rail 422 until the dust collection box 40 is completely pulled out from under the dust collection funnel 30. At this point, the dust collection box 40 protrudes from one side of the front panel 64 of the air conditioner, and the user can directly remove the dust collection box 40 from the front panel 64. To install the dust collection box 40, push or drive it backward; the roller 321 rolls backward along the guide rail 422 until the opening 41 of the dust collection box 40 aligns with the outlet 312 of the dust collection funnel 30, completing the assembly. When the guide rail 422 extends vertically along the air conditioner, it engages with the matching roller 321 to guide the dust collection box 40 to move vertically relative to the dust collection funnel 30. To remove the dust collection box 40, pull or drive it downwards; the roller 321 rolls downwards along the guide rail 422, and the dust collection box 40 gradually moves down from below the dust collection funnel 30 until it is completely detached. The user can then remove the dust collection box 40 directly from the bottom plate 65. To install the dust collection box 40, push or drive it upwards; the roller 321 rolls upwards along the guide rail 422 until the top of the dust collection box 40 contacts the bottom of the dust collection funnel 30, and the opening 41 of the dust collection box 40 precisely aligns with the outlet 312 of the dust collection funnel 30, completing the assembly.

[0042] Optionally, combined Figure 2 and Figure 3 As shown, the guide rail 422 extends in the front-to-back direction and is located on the side wall of the opening 41 of the dust collection box 40. The guide rail 422 has a U-shaped groove structure, and the opening of the U-shaped groove of the guide rail 422 is upward. The roller 321 is correspondingly located on the side wall of the outlet 312 of the dust collection funnel 30, and the installation height of the roller 321 is adapted to the installation height of the guide rail 422. The roller 321 can be embedded in the U-shaped groove through the opening of the guide rail 422 to form a rolling fit.

[0043] The U-shaped groove is a U-shaped or similar groove structure. The lateral clearance between the two side walls of the U-shaped groove and the roller 321 is controlled within a reasonable range, which can effectively limit the left and right deviation of the roller 321 while allowing the roller 321 to roll smoothly, so that the dust collection box 40 always maintains precise alignment with the dust collection funnel 30 during the movement in the front and back direction.

[0044] Optionally, combined Figure 3 and Figure 5 As shown, when the guide rail 422 extends in the front-back direction, the length of the guide rail 422 is greater than or equal to the length of the outlet 312 of the dust collection funnel 30 in the front-back direction, so as to reserve the extension space after the dust collection box 40 is completely pulled out.

[0045] This ensures that during the disassembly process, the rollers 321 of the dust collection box 40 remain within the constraint range of the guide rail 422, providing stable guidance throughout the process. This prevents the dust collection box 40 from tilting, sagging, or falling off due to loss of guidance during extraction, thereby improving the smoothness and safety of the disassembly operation.

[0046] Optionally, combined Figure 3 As shown, the rolling part 32 includes a first roller group 322 and a second roller group 323. The first roller group 322 is located on one side of the outlet 312 of the dust collection funnel 30 along the second direction; the second roller group 323 is located on the other side of the outlet 312 of the dust collection funnel 30 along the second direction. The rolling mating part 42 includes a first guide rail 423 and a second guide rail 424. The first guide rail 423 is located on one side of the opening 41 of the dust collection box 40 along the second direction and corresponds to and mates with the first roller group 322; the second guide rail 424 is located on the other side of the opening 41 of the dust collection box 40 along the second direction and corresponds to and mates with the second roller group 323. The second direction is the length direction or width direction of the outlet 312 of the dust collection funnel 30. The first roller group 322 includes a plurality of first rollers, which are spaced apart along the first direction. The second roller group 323 includes a plurality of second rollers, which are spaced apart along the first direction.

[0047] The first roller group 322 and the second roller group 323 are respectively located on both sides of the outlet 312 of the dust collection funnel 30 along its length. The first guide rail 423 and the second guide rail 424 are respectively located on both sides of the dust collection box 40 along the length of the outlet 312 of the dust collection funnel 30. Alternatively, the first roller group 322 and the second roller group 323 can be located on both sides of the outlet 312 of the dust collection funnel 30 along its width, and the first guide rail 423 and the second guide rail 424 can be respectively located on both sides of the dust collection box 40 along the width of the outlet 312 of the dust collection funnel 30. Each guide rail 422 forms a guide channel for the corresponding roller group 321 to be embedded and rolled. The two rows of roller groups 321 roll in cooperation with the corresponding first guide rail 423 and second guide rail 424, which enables the smooth movement of the dust collection box 40.

[0048] The opening 41 of the dust collection box 40 is rectangular, and the outlet 312 of the dust collection funnel 30 is also rectangular. The shape and size of the opening 41 of the dust collection box 40 and the outlet 312 of the dust collection funnel 30 are compatible, allowing for smooth dust collection. Based on the symmetry of the rectangular structure, rolling fit structures are symmetrically arranged on opposite sides of the opening 41 of the dust collection box 40 and the outlet 312 of the dust collection funnel 30, such as symmetrically arranged on the left and right sides along the width direction of the outlet 312 or on the front and rear sides along the length direction of the outlet 312. This symmetrical layout allows the dust collection box 40 to receive a balanced guiding force during movement, effectively avoiding movement jamming, skewing, or uneven wear of parts caused by unilateral force, thereby effectively improving the smoothness of movement. The specific positions of the first roller group 322, the second roller group 323, and the corresponding first guide rail 423 and second guide rail 424 must be compatible with the movement direction of the dust collection box 40 during assembly and disassembly.

[0049] When the dust collection box 40 moves in the front-back direction, the length direction of the outlet 312 of the dust collection funnel 30 is consistent with the front-back direction. The first guide rail 423 and the second guide rail 424 extend in the front-back direction. The first roller group 322 and the second roller group 323 can be symmetrically arranged on both sides of the width direction of the outlet 312 of the dust collection funnel 30, respectively, so as to form a stable support on the movement trajectory.

[0050] When the dust collection box 40 moves in the vertical direction, the first guide rail 423 and the second guide rail 424 extend in the vertical direction. The first roller group 322 and the second roller group 323 can be symmetrically arranged on both sides of the width direction of the dust collection funnel 30 outlet 312, or they can be symmetrically arranged on both sides of the length direction of the dust collection funnel 30 outlet 312. A balanced guiding force is applied from both sides of the movement trajectory of the dust collection box 40 to avoid force deviation caused by unilateral guidance.

[0051] Multiple first rollers and multiple second rollers are arranged at intervals along the first direction, that is, along the direction of movement of the dust collection box 40, forming evenly distributed support points along the movement trajectory of the dust collection box 40. On the one hand, this avoids a single roller 321 bearing the entire weight of the dust collection box 40, preventing local overload from causing deformation of the roller 321 or guide rail 422, and reducing component wear. On the other hand, the evenly distributed support points can distribute the weight of the dust collection box 40. Even if the dust accumulation inside the dust collection box 40 is uneven, the force can be balanced by multiple support points, avoiding movement jamming caused by local gravity concentration, allowing the dust collection box 40 to slide smoothly along the first direction.

[0052] Optionally, combined Figure 3 As shown, multiple first rollers are set up in a one-to-one correspondence with multiple second rollers.

[0053] Multiple first rollers are arranged in a one-to-one correspondence with multiple second rollers, that is, multiple first rollers and multiple second rollers are symmetrically distributed along the second direction, which can form a symmetrical guiding structure and prevent the dust collection box 40 from tilting to one side when it moves. Optionally, combined Figure 3 As shown, the dust collection funnel 30 is provided with a limiting part 33, and the dust collection box 40 is provided with a limiting fitting part 43. When the dust collection box 40 and the dust collection funnel 30 are assembled, the limiting part 33 and the limiting fitting part 43 cooperate to restrict the dust collection box 40 from detaching from the dust collection funnel 30.

[0054] When the dust collection box 40 is assembled with the dust collection funnel 30, the engagement of the limiting part 33 and the limiting mating part 43 locks the dust collection box 40 in place. This prevents the dust collection box 40 from disengaging in the direction perpendicular to the direction of movement (i.e., the first direction), such as accidental displacement in the left-right or up-down directions. Since the dust collection box 40 is located below the dust collection funnel 30, it tends to move downwards under gravity in the installed state. The locking structure of the limiting part 33 and the limiting mating part 43 effectively counteracts the effect of gravity and prevents the dust collection box 40 from falling. At the same time, this limiting structure does not affect the normal assembly and disassembly of the dust collection box 40 in the first direction and does not interfere with the rolling part 32 and the rolling mating part 42.

[0055] Optionally, combined Figure 3 As shown, one of the limiting part 33 and the limiting mating part 43 is a locking protrusion 331 and the other is a flange 431. When the dust collection box 40 is assembled with the dust collection funnel 30, the locking protrusion 331 and the flange 431 abut against each other in a direction perpendicular to the movement direction of the dust collection box 40, so as to limit the separation of the dust collection box 40 from the dust collection funnel 30 in a direction perpendicular to the movement direction of the dust collection box 40.

[0056] The direction of movement of the dust collection box 40 is the first direction. Through the abutment and limiting cooperation between the locking protrusion 331 and the flange 431, the separation of the dust collection box 40 from the dust collection funnel 30 in the direction perpendicular to the movement of the dust collection box 40 can be restricted, thereby improving the connection stability between the dust collection box 40 and the dust collection funnel 30, and also improving the movement stability of the dust collection box 40.

[0057] Optionally, combined Figure 3As shown, the rolling part 32 is a roller 321 provided in the dust collection funnel 30, and the roller 321 is rotatably connected to the dust collection funnel 30 through a bearing seat; the rolling engagement part 42 is a guide rail 422 provided in the dust collection box 40, and the roller 321 and the guide space of the guide rail 422 form a rolling engagement; the limiting part 33 includes a locking protrusion 331, which is provided on the outside of the bearing seat; the limiting engagement part 43 includes a flange 431, and the upper edge of the side wall of the guide rail 422 extends inward to form a flange 431, and the flange 431, together with the side wall and bottom wall of the guide rail 422, forms a semi-enclosed guide space; when the dust collection box 40 is installed, the roller 321 is embedded in the guide space of the guide rail 422, and the locking protrusion 331 is simultaneously located in the guide space, and the locking protrusion 331 can abut against the flange 431 to limit the dust collection box 40 from disengaging from the dust collection funnel 30 in the first upward direction. The locking protrusion 331 is located on the outside of the bearing seat and is adapted to the flange 431 extending from the upper edge of the side wall of the guide rail 422. When the dust collection box 40 is installed, the roller 321 is embedded in the semi-enclosed guide space of the guide rail 422, and the locking protrusion 331 is simultaneously located in the space and abuts against the flange 431. This abutting structure can precisely limit the detachment of the dust collection box 40 in the direction perpendicular to the first direction (such as the up and down direction). When the dust collection box 40 moves along the first direction, the flange 431 is always abutted against and limited by the locking protrusion 331. Because the dust collection box 40 is located below the funnel, it always has a downward tendency due to gravity. The abutment between the locking protrusion 331 and the flange 431 can form a reverse support force to counteract the effect of gravity and prevent the dust collection box 40 from falling from below the funnel. At the same time, the side wall of the semi-enclosed guide space can help limit the lateral displacement of the dust collection box 40. In addition, the flange 331 is integrated on the outside of the bearing housing and can be integrally injection molded or stamped with the bearing housing. The flange 431 is directly extended from the side wall of the guide rail 422, eliminating the need for additional independent limiting parts 33, thus reducing the number of parts.

[0058] Optionally, combined Figure 3 As shown, the upper edges of the two side walls of the guide rail 422 extend inward to form two symmetrical flanges 431. Two locking protrusions 331 are provided on the symmetrical sides above the roller 321, and the two locking protrusions 331 correspond to and abut against the two flanges 431 one by one.

[0059] When the dust collection box 40 is installed, the roller 321 is embedded in the semi-enclosed guide space of the guide rail 422, and the two locking protrusions 331 simultaneously abut against the two flanges 431. The symmetrically arranged limiting abutment structure can evenly apply reverse support force from both sides of the roller 321, preventing the dust collection box 40 from detaching perpendicularly to the first direction. The cooperation between the symmetrical flanges 431 and the locking protrusions 331 can also limit the left and right displacement of the dust collection box 40, preventing the guide rail 422 from tilting due to vibration.

[0060] It is understandable that the limiting part 33 and the limiting mating part 43 can also be a limiting mating structure such as a hook and a groove, or a flange 431 and a notch.

[0061] Optionally, combined Figure 4-6 As shown, the filter self-cleaning device for an air conditioner also includes a first transmission member 34, a second transmission member 44, and a drive motor 50. The first transmission member 34 is disposed in the dust collection funnel 30; the second transmission member 44 is disposed in the dust collection box 40, and the first transmission member 34 and the second transmission member 44 are in a transmission engagement; the drive motor 50 is drivenly connected to the first transmission member 34 or the second transmission member 44, so as to drive the dust collection box 40 to move relative to the dust collection funnel 30 through the transmission engagement of the first transmission member 34 and the second transmission member 44.

[0062] The drive motor 50 drives the first transmission component 34 or the second transmission component 44, causing the first transmission component 34 and the second transmission component 44 to form a stable transmission engagement, thereby driving the dust collection box 40 to move relative to the dust collection funnel 30, enabling the automatic installation and removal of the dust collection box 40. Users do not need to directly contact the dust collection box 40; they only need to issue a command through the air conditioner's control panel or remote control to trigger the drive motor 50 to work, completing the automatic extraction or insertion of the dust collection box 40, thus improving operational convenience.

[0063] Optionally, combined Figure 4 and Figure 6 As shown, the first transmission component 34 includes a gear 341, which is disposed on the side wall of the dust collection funnel 30; the second transmission component 44 includes a rack 441, which is disposed on the side wall of the dust collection box 40 and extends along a first direction, and the gear 341 meshes with the rack 441; wherein, the gear 341 is driven to connect with the drive motor 50, and the drive motor 50 drives the gear 341 to rotate to drive the rack 441 to move, thereby driving the dust collection box 40 to move relative to the dust collection funnel 30 along the first direction.

[0064] The first transmission component 34 is a gear 341 located on the side wall of the dust collection funnel 30, and the second transmission component 44 is a rack 441 located on the side wall of the dust collection box 40 and extending along the first direction. The gear 341 and the rack 441 mesh with each other, and the transmission direction is consistent with the movement direction of the dust collection box 40 and the extension direction of the guide rail 422. Through the transmission cooperation between the gear 341 and the rack 441, the accuracy and stability of the automatic movement of the dust collection box 40 can be improved. When the drive motor 50 drives the gear 341 to rotate, the rack 441 can move in a uniform linear motion along the first direction, driving the dust collection box 40 to move smoothly, so that the dust collection box 40 can accurately reach the preset position of being fully pulled out or fully installed, avoiding the dust collection box 40 from being misaligned with the funnel outlet 312 due to stroke deviation or from impacting the internal structure due to excessive movement. The program control of the drive motor 50 can replace the traditional mechanical stop structure. When the dust collection box 40 moves to the fully installed or fully withdrawn position, the motor automatically stops, which can prevent excessive movement of the dust collection box 40 and reduce independent stop components. At the same time, the rigid support of the meshing transmission can counteract the eccentric force caused by uneven dust distribution inside the dust collection box 40. Combined with the guidance of the roller 321 and guide rail 422, the stability of the dust collection box 40's movement is improved. In addition, the gear 341 and rack 441 transmission structure is compact, occupies little space, and is suitable for the narrow installation environment inside the air conditioner.

[0065] The dust collection box 40 and the dust collection funnel 30 are connected by a guide rail 422 and a roller 321. The dust collection box 40 can be removed for cleaning by manually pulling it out. Alternatively, the gear 341 can be connected to the dust collection funnel 30, and the rack 441 can be fixedly connected to the dust collection box 40. The gear 341 and rack 441 are driven by the drive motor 50, so that the gear 341 drives the rack 441 to move, thereby causing the dust collection box 40 to move automatically.

[0066] Gear 341 and rack 441 form a separable transmission engagement. After the dust collection box 40 is disassembled, rack 441 disengages from gear 341 along with the dust collection box 40, without structural jamming, allowing the dust collection box 40 to be easily and completely removed without disassembling the transmission components, making cleaning convenient. During the installation of the dust collection box 40, as it is pushed in along guide rail 422, rack 441 automatically aligns with and re-engages with gear 341. At this time, the guiding action of guide rail 422 provides auxiliary positioning, eliminating the need for manual adjustment. After installation, the automatic transmission function can be restored by drive motor 50.

[0067] Optionally, combined Figure 2 and Figure 5 As shown, the inlet area 311 of the dust collection funnel 30 is larger than the outlet area 312. The dust collection funnel 30 includes a first sidewall and a second sidewall opposite to each other. The first sidewall is inclined toward the second sidewall along the direction from the inlet 311 toward the outlet 312, forming a funnel-shaped dust guiding cavity 31.

[0068] The inlet area 311 of the dust collection funnel 30 is larger than the outlet area 312, which expands the dust collection range and guides dust to naturally converge in the dust guiding chamber 31, avoiding accumulation and blockage. The smaller outlet 312 can also precisely fit the dust collection box 40. The first sidewall is inclined towards the second sidewall along the direction from the inlet 311 to the outlet 312, forming a funnel-shaped guide channel that converges towards the outlet 312, accelerating the flow of dust to the outlet 312 and preventing dust from accumulating and remaining in the dust collection funnel 30. Alternatively, the first sidewall can be inclined towards the second sidewall along the direction from the inlet 311 to the outlet 312, and the second sidewall can be inclined towards the first sidewall along the direction from the inlet 311 to the outlet 312. By setting both the first and second sidewalls inclined, the dust guiding effect can be effectively improved.

[0069] Optionally, combined Figure 6 As shown, the filter self-cleaning device for an air conditioner also includes a roller assembly and a traction rope 93. The roller assembly includes a first roller 91 and a second roller 92. A first end of the filter 10 along its own length is wound and connected to the first roller, and a second end of the filter 10 along its own length is wound and connected to the second roller. When one of the first roller and the second roller is wound up, the other is released, which drives the filter 10 to reciprocate along its own length. One end of the traction rope 93 is wound and connected to the first roller, and the other end is wound and connected to the second roller. When one end of the traction rope is wound up, the other end is released. One end is released; wherein, the cleaning component 20, the dust collection funnel 30 and the dust collection box 40 are all correspondingly provided at the same end along the length of the filter screen 10, and the cleaning component 20 maintains contact with the filter screen 10 in motion; the first end of the filter screen 10 and the first end of the traction rope 93 are wound in opposite directions and connected to the first reel 91, and the second end of the filter screen 10 and the second end of the traction rope 93 are wound in opposite directions and connected to the second reel 92; when the first reel rotates in the forward direction to reel in the filter screen 10, the traction rope is released simultaneously, and when the first reel rotates in the reverse direction to release the filter screen 10, the traction rope is reeled in simultaneously.

[0070] The filter 10 is driven to reciprocate along its length by a roller assembly, forming a single-layer filter structure, which improves air intake efficiency. The cleaning component 20, dust collection funnel 30, and dust collection box 40 are located at the same end along the length of the filter 10, making the overall structure of the filter self-cleaning device more compact and allowing for concentrated use of the limited space at the end of the filter 10, adapting to the narrow installation environment inside the air conditioner. The filter 10 and the traction rope are connected and wound in opposite directions on the first and second rollers. The traction rope indirectly drives the filter 10 to reciprocate by pulling the first and second rollers to wind or release. This effectively reduces the tensile force on both ends of the filter 10, thereby reducing the risk of damage during the cleaning process. Simultaneously, the traction rope, as a transmission component, has the advantages of low cost and small size, which not only reduces production costs but also improves space utilization, making the layout of the entire filter self-cleaning device within the air conditioner more flexible. In addition, the cleaning component is in continuous contact with the filter 10 during its movement, which can effectively remove dust from the filter 10 and improve the air conditioner's filtration performance and indoor air quality.

[0071] Combination Figure 1 and Figure 10 As shown, this embodiment of the present disclosure provides an air conditioner, including a housing 60 and a filter self-cleaning device for an air conditioner as described in any of the above-disclosed embodiments. The housing 60 is provided with an air inlet 61; the filter self-cleaning device is disposed inside the housing 60, and the filter 10 of the filter self-cleaning device is disposed at the air inlet 61.

[0072] The air conditioner provided in this embodiment includes the filter self-cleaning device for air conditioners as described in any of the above-described embodiments, and therefore has all the beneficial effects of the filter self-cleaning device for air conditioners as described in any of the above-described embodiments, which will not be repeated here.

[0073] Optionally, combined Figure 1 and Figure 10 As shown, the housing 60 has an air duct space 62 and an auxiliary space 63. The air inlet 61 is located on the top of the housing 60 and is connected to the air duct space 62. The filter 10 is installed in the air duct space 62. The air conditioner also includes a cross-flow fan 70, which is located in the air duct space 62 and is installed in the air inlet 61. The air duct space 62 and the auxiliary space 63 are arranged along the axial direction of the cross-flow fan 70. The auxiliary space 63 is located at the end of the air duct space 62 along the axial direction of the cross-flow fan 70. The filter 10 is located between the cross-flow fan 70 and the air inlet 61, and the length of the filter 10 extends along the axial direction of the cross-flow fan 70. The dust collection funnel 30 and the dust collection box 40 are located in the auxiliary space 63.

[0074] By constructing an air duct space 62 and an auxiliary space 63 within the housing 60, and arranging the air duct space 62 and auxiliary space 63 along the axial direction of the cross-flow fan 70, space optimization can be achieved while realizing functional integration. The air duct space 62 is used to accommodate the cross-flow fan 70 and the filter 10, while the auxiliary space 63, located at the end of the air duct space 62, is used to accommodate the dust collection funnel 30 and the dust collection box 40. This partitioned layout ensures that the dust collection funnel 30, the dust collection box 40, and the cleaning component 20 of the filter self-cleaning device do not occupy the core airflow path space of the air duct, avoiding component obstruction and thus reducing airflow. At the same time, the cleaning component 20 and the dust collection funnel 30 are located within the auxiliary space 63, achieving an ultra-thin structure and avoiding occupying space in the overall length and height of the machine.

[0075] Optionally, combined Figure 10 As shown, the housing 60 includes a front panel 64, which has a first operation port 641. The first operation port 641 is connected to the auxiliary space 63 and corresponds to the front end of the dust collection box 40. The dust collection box 40 can move inside and outside the auxiliary space 63 through the first operation port 641.

[0076] By providing a first operating port 641 on the front panel 64, a convenient path for removing and placing the dust collection box 40 can be provided without disassembling the panel. The size of the first operating port 641 is adapted to the size of the dust collection box 40. The first operating port 641 directly connects to the auxiliary space 63 and corresponds to the front end of the dust collection box 40. Users can directly pull out the dust collection box 40 through the first operating port 641, which can effectively improve the convenience of cleaning and maintenance.

[0077] Optionally, combined Figure 7 and Figure 8 As shown, the housing 60 includes a front panel 64 and a bottom plate 65. The air conditioner also includes an air guide baffle 80. The lower end of the front panel 64 and the front end of the bottom plate 65 of the housing 60 form an air outlet 67. The air guide baffle 80 is movably disposed at the air outlet to open or close the air outlet. The dust collection box 40 is located on the lower side of the front panel 64 and inside the air guide baffle 80. When the air guide baffle 80 is in the closed state, it can cover the dust collection box 40. When the air guide baffle 80 is in the open state, it can expose the dust collection box 40 so that the dust collection box 40 can be directly taken out and put in.

[0078] The dust collection box 40 is located inside the air guide baffle 80, eliminating the need for an additional operating port on the front panel 64 and maintaining the integrity of the air conditioner's appearance. When the air guide baffle 80 is closed, it completely conceals the dust collection box 40, preventing dust or foreign objects from falling into it and avoiding any visual impact. Utilizing the existing structure of the air guide baffle 80, the dust collection box 40 is concealed and easily accessible. Users can simply open the air guide baffle 80 in the conventional way to reveal the inner dust collection box 40 without disassembling any other components.

[0079] Optionally, combined Figure 7 and Figure 8 As shown, the air outlet corresponds to the air duct space 62. A connecting plate 66 is connected between the lower end of the front panel 64 of the housing 60 and the front end of the bottom plate 65. The connecting plate 66 corresponds to the auxiliary space 63 and is located inside the air guide plate. The connecting plate 66 is provided with a third operation port 661. The dust collection box 40 is correspondingly arranged with the third operation port 661. Part of the dust collection box 40 abuts against the bottom wall of the third operation port 661 to support the dust collection box 40.

[0080] Part of the dust collection box 40 abuts against the bottom wall of the third operating port 661, and the bottom wall provides stable support for the dust collection box 40, which can prevent the dust collection box 40 from shifting.

[0081] Optionally, combined Figure 9 As shown, the housing 60 includes a base plate 65, and the base plate 65 has a second operation port 651. The second operation port 651 is connected to the auxiliary space 63 and corresponds to the bottom end of the dust collection box 40. The dust collection box 40 can move inside and outside the auxiliary space 63 through the second operation port 651.

[0082] By providing a second operating port 651 on the base plate 65, a convenient path for removing and placing the dust collection box 40 can be provided without disassembling the panel. The size of the second operating port 651 is adapted to the size of the dust collection box 40. The second operating port 651 directly connects to the auxiliary space 63 and corresponds to the bottom of the dust collection box 40. Users can directly pull out the dust collection box 40 through the second operating port 651, which can effectively improve the convenience of cleaning and maintenance.

[0083] The foregoing description and accompanying drawings fully illustrate 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. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments. 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 its scope.
