In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] The present invention provides a dust removal device, please refer to Figures 1 to 5 , having a filter element 20 and a first cleaning element 10 for cleaning the first side of the filter element 20, and the filter element 20 moves back and forth along a preset trajectory; the dust removal device also includes: a second cleaning element 30, which is arranged on opposite sides of the preset trajectory with the first cleaning element 10, and the second cleaning element 30 is used to clean the second side of the filter element 20.

[0029] The dust removal device of the present invention has a filter element 20 and a first cleaning element 10. The dust removal device also includes a second cleaning element 30. The filter element 20 moves back and forth along a preset trajectory. The first cleaning element 10 cleans the first side of the filter element 20. The second cleaning element 30 and the first cleaning element 10 are arranged on opposite sides of the preset trajectory and are used to clean the second side of the filter element 20. In the process of the filter element 20 moving back and forth along the preset trajectory, the first side and the second side of the filter element 20 are both cleaned by the first cleaning element 10 and the second cleaning element 30, which solves the problem that both the inside and outside of the filter net cannot be completely cleaned.

[0030] It should be noted that the filter element 20 located in the first movable channel 81 is used to filter the air entering from the air inlet 80. The first side of the filter element 20 is the air inlet side when the filter element 20 filters the air, and the second side of the filter element 20 is the leeward side when the filter element 20 filters the air; that is, when the filter element 20 filters the air, the first side of the filter element 20 is located on the side of the second side close to the air inlet 80.

[0031] Specifically, the first cleaning member 10 and the second cleaning member 30 are both brushes.

[0032] In this embodiment, if Figure 1As shown, the dust removal device also includes a first rotating part 50, which is rotatably arranged, and part of the filter element 20 is wound around the first rotating part 50; the filter element 20 is arranged at the air inlet 80 of the dust removal device; the dust removal device has a first moving channel 81, a second moving channel 82 and a third moving channel 83, and the first moving channel 81 and the third moving channel 83 are connected through the second moving channel 82; the second moving channel 82 is arranged around the circumference of the first rotating part 50, and the first moving channel 81 is located on the side of the third moving channel 83 close to the air inlet 80; the filter element 20 reciprocates in the first moving channel 81, the second moving channel 82 and the third moving channel 83; wherein the first cleaning element 10 is located on one side of the second moving channel 82 or one side of the third moving channel 83; the second cleaning element 30 is located on the other side of the third moving channel 83.

[0033] During specific implementation, the filter element 20 moves back and forth in the first moving channel 81, the second moving channel 82 and the third moving channel 83 driven by the first rotating part 50. During the reciprocating movement of the filter element 20, the first cleaning element 10 and the second cleaning element 30 clean both sides of the filter element 20.

[0034] Specifically, the filter element 20 includes a filter body 21 and a transmission part 22, the filter body 21 is a filter net, the transmission part 22 has a first meshing tooth, the first rotating part 50 includes a transmission gear 52, the transmission gear 52 has a second meshing tooth, and the transmission part 22 and the transmission gear 52 are meshed and connected through the first meshing tooth and the second meshing tooth.

[0035] Optionally, there are two transmission parts 22, which are located on opposite sides of the filter body 21. The first rotating part 50 includes two transmission gears 52. The two transmission parts 22 are arranged in a one-to-one correspondence with the two transmission gears 52, and each transmission part 22 is meshed with a corresponding transmission gear 52. This arrangement enables the first rotating part 50 to reliably drive the filter element 20.

[0036] During specific implementation, when the filter element 20 is in the working state, at least part of it is located in the first moving channel 81 and is arranged opposite to the air inlet 80 to filter the wind entering the air conditioner from the air inlet 80; when the filter element 20 is in the cleaning state, it moves from the first moving channel 81 to the second moving channel 82 through the meshing action of its transmission part 22 and the transmission gear 52 of the first rotating part 50. Since the second moving channel 82 is arranged circumferentially around the first rotating part 50, the moving direction of the filter element 20 is reversed, thereby entering the third moving channel 83. In the process of the filter element 20 entering the third moving channel 83 from the second moving channel 82, the first side of the filter element 20 is cleaned by the first cleaning element 10, and the second side of the filter element 20 is cleaned by the second cleaning element 30.

[0037] Specifically, if Figure 4 As shown, the dust removal device also includes a first plate 84 and a second plate 85, the air inlet 80 is arranged through the first plate 84, and a partition is provided between the first plate 84 and the second plate 85. At least a portion of the first moving channel 81 is formed between the first plate 84 and the partition, and at least a portion of the third moving channel 83 is formed between the second plate 85 and the partition.

[0038] Specifically, the partition is a plate-shaped structure.

[0039] In this embodiment, if Figure 1 and Figure 3 As shown, the dust removal device also includes: a support frame 60 for supporting the filter element 20, and the filter element 20 moves back and forth along the surface of the support frame 60; the surface of the support frame 60 includes a first supporting surface 62, and the first supporting surface 62 has a first supporting end and a second supporting end arranged in sequence along the moving direction of the filter element 20; in the direction from the first supporting end to the second supporting end, the first supporting surface 62 is inclined upward relative to the horizontal plane; the second cleaning member 30 is arranged opposite to at least part of the first supporting surface 62 and is spaced apart from the first supporting surface 62, and the second cleaning member 30 is located between the first supporting end and the second supporting end; the second cleaning member 30 contacts the second side of the filter element 20, and the second cleaning member 30 has a first cleaning end and a second cleaning end arranged in sequence along its extension direction; the first cleaning end extends to the edge of the filter element 20 or protrudes from the edge of the filter element 20, and the first cleaning end is arranged lower than the second cleaning end.

[0040] During specific implementation, the second cleaning member 30 is located between the first supporting end and the second supporting end of the first supporting surface 62, and the first supporting surface 62 is inclined upward relative to the horizontal plane in the direction from the first supporting end to the second supporting end; the first cleaning end of the second cleaning member 30 extends to the edge of the filter element 20 or protrudes from the edge of the filter element 20, so that the dust cleaned by the second cleaning member 30 from the filter element 20 can fall along the first cleaning end and will not continue to remain on the surface of the filter element 20, and the first cleaning end is lower than the second cleaning end, so that the dust moves to the first cleaning end due to gravity.

[0041] Optionally, the first supporting surface 62 is an arcuate surface. The setting of the arcuate surface enables the filter element 20 to completely fit with the first side of the first supporting surface 62 during movement, thereby making the second cleaning element 30 more fully in contact with the second side of the filter element 20.

[0042] Specifically, the dust removal device also includes a dust removal main body, which includes the above-mentioned first plate 84, second plate 85 and partition; the dust removal main body cover is arranged on the drive box 110, and the two ends of the support frame 60 are fixed parts, and the two fixed parts are clamped between the dust removal main body and the drive box 110 to fix the support frame 60.

[0043] In this embodiment, the first cleaning member 10 is rotatably provided; and / or the second cleaning member 30 is rotatably provided. Specifically, the first cleaning member 10 and the second cleaning member 30 are respectively driven by a motor to achieve rotation.

[0044] In specific implementation, such a setting enables the first cleaning member 10 and the second cleaning member 30 to be in contact with the filter member 20 on all surfaces in the circumferential direction when in the cleaning state, thereby avoiding the filter member 20 contacting only a part of the first cleaning member 10 and the second cleaning member 30, which affects the service life of the first cleaning member 10 and the second cleaning member 30.

[0045] In specific implementation, the filter element 20 moves counterclockwise under the drive of the first rotating part 50, enters the second moving channel 82 from the first moving channel 81, and then enters the third moving channel 83. During this movement, the first cleaning element 10 and the second cleaning element 30 move clockwise to clean the filter element 20. This arrangement enhances the cleaning effect.

[0046] In this embodiment, if Figure 3 As shown, the dust removal device further includes: a pressing portion 40 , which is arranged on two opposite sides of the filter element 20 with the first cleaning element 10 , and the pressing portion 40 is pressed on the second side of the filter element 20 .

[0047] In a specific implementation, the arrangement of the pressing portion 40 keeps the filter element 20 in a tense state during movement, ensuring that the filter element 20 can be in close contact with the first cleaning element 10, so that the first side of the filter element 20 can be effectively cleaned.

[0048] In this embodiment, if Figure 3 As shown, the dust removal device further includes: a support frame 60 for supporting the filter element 20, the support frame 60 has an avoidance opening, and the first cleaning element 10 contacts the filter element 20 through the avoidance opening.

[0049] During specific implementation, the setting of the avoidance port prevents the first side of the filter element 20 from being blocked by the support frame 60, and the filter element 20 contacts the first cleaning element 10 through the avoidance port, so that the first side thereof is fully cleaned; and, a movement space is provided for the pressing portion 40 to press the filter element 20 so that the filter element 20 is in a taut state.

[0050] Specifically, the avoidance opening is arranged opposite to the first cleaning member 10 and passes through the support frame 60 .

[0051] In this embodiment, if Figure 3 As shown, the pressing portion 40 is used to be pressed on the middle part of the filter element 20; the dust removal device also includes: a connecting rod 61, and the pressing portion 40 is connected to the support frame 60 through the connecting rod 61.

[0052] During specific implementation, the connecting rod 61 enables the pressing part 40 to be stably connected to the support frame 60, so that there is a certain distance between the pressing part 40 and the support frame 60, so that the filter element 20 can be pressed by the pressing part 40 and can also pass through the gap between the pressing part 40 and the support frame 60.

[0053] Specifically, the width of the pressing portion 40 is smaller than the width of the filter element 20 , and the pressing portion 40 is pressed on the middle portion of the filter element 20 , so that the filter element 20 is in a tight state.

[0054] In this embodiment, if Figure 2 As shown, the dust removal device also includes: a second rotating part 70, which is rotatably arranged; a connecting member 100, the first end of the connecting member 100 is connected to the second rotating part 70, and the second end of the connecting member 100 is connected to the filter element 20; wherein, the second movable channel 82 is located on the side of the first rotating part 50 away from the second rotating part 70.

[0055] In a specific implementation, the arrangement of the connecting member 100 and the second rotating portion 70 enables the filter element 20 to be converted from a cleaning state to a working state. In the working state, at least a portion of the filter element 20 is arranged opposite to the air inlet 80 .

[0056] Specifically, the first rotating portion 50 is driven to rotate by the first driving member 51, and the second rotating portion 70 is driven to rotate by the second driving member 71. Driven by the first rotating portion 50, the filter element 20 enters a cleaning state, passing from the first moving channel 81 to the second moving channel 82, and then to the third moving channel 83. Driven by the second rotating portion 70, the filter element 20 enters a working state, passing from the third moving channel 83 to the second moving channel 82, and then to the first moving channel 81. Both the first driving member 51 and the second driving member 71 are motors.

[0057] Specifically, the connector 100 is a flexible member. When the second rotating portion 70 drives the first end of the connector 100 to rotate, the connector 100 is wrapped around the second rotating portion 70, and the second end of the connector 100 drives the filter 20 to move opposite to the air inlet 80.

[0058] In this embodiment, the dust removal device further includes: a dust collecting box 90, which is located below the first cleaning member 10 and the second cleaning member 30. The dust collecting box 90 has a dust collecting port 91 for collecting dust.

[0059] Specifically, the dust box 90 is detachably disposed in the dust removal device. When the dust box 90 is full of dust, it can be directly drawn out for cleaning.

[0060] Specifically, the dust collecting port 91 is provided at the top of the dust collecting box 90 to receive the dust dropped by the first cleaning member 10 and the second cleaning member 30 .

[0061] In a specific implementation, the dust removal device further includes a drive box 110 for accommodating the first rotating portion 50, the first cleaning member 10, the second cleaning member 30, and the support frame 60. The drive box 110 is snap-connected to the dust removal body; a dust removal body cover is provided on the opening of the drive box 110. The dust collection box 90 is retractably disposed within the drive box 110, and the dust collection port 91 is in communication with the cavity of the drive box 110.

[0062] The present invention also provides an air-conditioning indoor unit, comprising the dust removal device in the above embodiment.

[0063] The present application solves the following technical problems: it solves the problem that the filter element 20 of the air conditioner indoor unit is clogged with dirt and needs to be frequently disassembled and cleaned, which is inconvenient to operate.

[0064] This application has the following beneficial effects:

[0065] The automatic dust removal of the indoor unit of the air conditioner can be realized, and the filter element 20 can always be kept clean, thereby ensuring the cooling and heating performance of the air conditioner and eliminating health hazards; it solves the problem that the filter element 20 of the existing air conditioner needs to be manually disassembled and cleaned, and the filter element 20 can be effectively cleaned without disassembling it.

[0066] This application has the following invention points:
