[0060] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0061] The following describes a filter cleaning system 1 for an air conditioner according to an embodiment of the present invention with reference to the accompanying drawings.

[0062] like Figure 1 , Figure 3 As shown, the filter cleaning system 1 of the air conditioner according to the embodiment of the present invention includes a housing 10 , a cleaning device and a sterilizing device 30 .

[0063] The shell 10 defines a water storage chamber 11, and the cleaning device is disposed in the shell 10. The cleaning device includes a cleaning member, which is rotatably disposed in the water storage chamber 11 to clean the filter 64. When the water level in the water storage chamber 11 reaches a preset water level, at least a portion of the cleaning member is immersed in water to wet the cleaning member, and then when the cleaning member rotates, the cleaning member can brush the filter 64.

[0064] Specifically, when the cleaning piece cleans the filter 64, dirt such as hair and dust on the filter 64 will adhere to the cleaning piece. When the cleaning piece rotates, the water in the water storage chamber 11 can clean the cleaning piece on the one hand, and provide enough water for the cleaning piece on the other hand, so that the cleaning piece can clean the filter 64.

[0065] The sterilization device 30 is arranged in the shell 10, and is used to sterilize the water in the water storage chamber 11 to prevent bacteria and other microorganisms from growing in the water storage chamber 11. At the same time, when the water level in the water storage chamber 11 reaches a preset state, at least a part of the cleaning element is immersed in water. The water in the water storage chamber 11 can sterilize the cleaning element to prevent excessive bacteria from growing on the cleaning element, thereby enabling the cleaning element to better clean the filter 64.

[0066] Among them, after the sterilization device 30 has sterilized the water in the water storage chamber 11, when the cleaning part uses the water in the water storage chamber 11 to clean the filter 64, on the one hand, it can clean the filter 64, and on the other hand, it can also use the water in the water storage chamber 11 to sterilize the filter 64. That is to say, the cleaning part can sterilize the filter 64 while removing dust and hair on the filter 64, and thus can fully clean the filter 64 to prevent excessive bacteria from growing on the filter 64. When the user uses the air conditioner 7, the cleanliness of the air outlet of the air conditioner 7 can be improved, thereby improving the user experience.

[0067] Therefore, the filter cleaning system 1 of the air conditioner according to the embodiment of the present invention utilizes the sterilization device 30 to sterilize the water in the water storage chamber 11. By sterilizing the water in the water storage chamber 11, the cleaning component can also sterilize the filter 64 when using the water in the water storage chamber 11 to clean the filter 64, thereby reducing the bacteria growing on the filter 64 and improving the cleanliness of the air outlet of the air conditioner 7.

[0068] The following describes a filter cleaning system 1 for an air conditioner according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0069] like Figure 1 , Figure 3 As shown, the filter cleaning system 1 of the air conditioner according to the embodiment of the present invention includes a housing 10 , a cleaning device and a sterilizing device 30 .

[0070] In some embodiments of the present invention, Figure 3 As shown, the sterilization device 30 includes a storage box 400 and a feeding assembly 300. The storage box 400 is used to store sterilization raw materials 63. The feeding assembly 300 is arranged on the shell 10, and is used to transport the sterilization raw materials 63 to the water storage chamber 11, so as to be able to sterilize the water in the water storage chamber 11. When the cleaning part uses the water in the water storage chamber 11 to clean the filter 64, the cleaning part can sterilize the filter 64 while cleaning the filter 64.

[0071] In some embodiments, the sterilization raw material 63 may be in a solid state. After the feeding component 300 feeds the sterilization raw material 63 into the water storage chamber 11 , the sterilization raw material 63 dissolves in water and can sterilize the water in the water storage chamber 11 .

[0072] For example, the sterilizing raw material 63 can be bleaching powder, which contains calcium hydroxide, calcium chloride and calcium hypochlorite. When bleaching powder is dissolved in water, it will produce extremely unstable hypochlorous acid. At this time, the hypochlorous acid decomposes to produce chlorine atoms and oxygen atoms. Through the effects of oxidation and chlorination, the chlorine atoms and oxygen atoms will produce a strong sterilization effect, quickly eliminating bacterial spores, viruses and fungi in the water in the water storage chamber 11.

[0073] In other embodiments, the sterilization raw material 63 may be a liquid. After the feeding component 300 delivers the sterilization raw material 63 to the water storage chamber 11, the sterilization raw material 63 may sterilize the water in the water storage chamber 11. For example, the sterilization raw material 63 may be a hypochlorous acid solution, and the hypochlorous acid solution may sterilize the water in the water storage chamber 11.

[0074] In some optional embodiments of the present invention, the feeding assembly 300 includes a feeding piece 310 and a feeding drive piece. The feeding piece 310 can be movably disposed in the water storage chamber 11. The feeding piece 310 has a feeding portion for accommodating the sterilization raw material 63. The feeding drive piece is suitable for cooperating with the feeding piece 310, and is used to drive the feeding piece 310 to move to transport the sterilization raw material 63, so as to deliver the sterilization raw material 63 to the water storage chamber 11, thereby achieving sterilization treatment of the water in the water storage chamber 11.

[0075] In some embodiments, the feeding member 310 is formed as a conveyor belt, and the feeding drive member includes a first pulley, a second pulley and a motor; or, the feeding member 310 is formed as a chain portion, and the feeding drive member includes a first sprocket portion, a second sprocket portion and a motor. The feeding drive member can drive the feeding member 310 to move. When the feeding member 310 drives the sterilization raw material 63 to move to a designated position, the sterilization raw material 63 falls into the water storage chamber 11 or contacts the water in the water storage chamber 11 to deliver the sterilization raw material 63 to the water storage chamber 11.

[0076] In other embodiments, the feeding member 310 and the feeding driving member cooperate through gear racks, and the feeding driving member can drive the feeding member 310 to move. When the feeding member 310 drives the sterilization raw material 63 to move to a designated position, the sterilization raw material 63 falls into the water storage chamber 11 or contacts with the water in the water storage chamber 11 to deliver the sterilization raw material 63 to the water storage chamber 11.

[0077] In some optional embodiments of the present invention, Figure 4 , Figure 5 As shown, the feeding piece 310 is a rotatable disc structure, and the feeding part is a feeding trough 311 arranged on the peripheral wall of the feeding piece 310. The sterilization raw material 63 in the storage box 400 can fall into the feeding trough 311. When the feeding piece 310 rotates, the feeding trough 311 rotates around its rotation center and delivers the sterilization raw material 63 therein to the water storage chamber 11.

[0078] In some embodiments, the feeding drive member can be a motor, which can drive the feeding member 310 to rotate. At this time, the feeding trough 311 rotates downward around the rotation center of the feeding member 310 so that the sterilization material 63 in the feeding trough 311 can fall into the water storage chamber 11.

[0079] In other embodiments, Figure 4 As shown, the feeding drive member is a floating member 320, and the floating member 320 is arranged in the water storage chamber 11 so as to float up and down according to the water level in the water storage chamber 11. When the water level in the water storage chamber 11 rises, the floating member 320 can move upward, and the floating member 320 cooperates with the feeding member 310 to drive the feeding member 310 to rotate when the floating member 320 moves up and down.

[0080] In some examples, the floating member 320 includes a rack portion, and the feeding member 310 has a gear portion, and the gear portion and the rack portion are meshed for transmission. When the floating member 320 moves upward, the floating member 320 can drive the feeding member 310 to rotate. At this time, the feeding trough 311 rotates downward around the rotation center of the feeding member 310, so that the sterilization raw material 63 in the feeding trough 311 can fall into the water storage chamber 11.

[0081] In other examples, such as Figure 5 As shown, the feeding member 310 has a first toggle portion 312. When the floating member 320 moves upward, the floating member 320 drives the feeding member 310 to rotate by toggling the first toggle portion 312. At this time, the feeding trough 311 rotates downward around the rotation center of the feeding member 310 so that the sterilization material 63 in the feeding trough 311 can fall into the water storage chamber 11.

[0082] In some optional embodiments of the present invention, Figure 4 As shown, the feeding drive member is a floating member 320, which is arranged in the water storage chamber 11 and can float up and down according to the water level in the water storage chamber 11, wherein the feeding member 310 has a first toggle portion 312, and the floating member 320 drives the feeding member 310 to move by toggling the first toggle portion 312, so that the feeding member 310 can deliver the sterilization raw material 63 at the feeding portion to the water storage chamber 11 when it is active.

[0083] In some examples, such as Figure 4 , Figure 5 As shown, the feeding member 310 is a rotatable disc structure. When the water level in the water storage chamber 11 rises, the floating member 320 drives the feeding member 310 to rotate by toggling the first toggle portion 312. At this time, the feeding portion rotates downward around the rotation center of the feeding member 310, so that the sterilization material 63 on the feeding portion can fall into the water storage chamber 11, or the sterilization material 63 on the feeding portion can contact the water in the water storage chamber 11.

[0084] In other embodiments, the feeding member 310 is a swingable rod-shaped structure. When the water level in the water storage chamber 11 rises, the floating member 320 drives the feeding member 310 to swing by toggling the first toggle portion 312. At this time, the feeding portion swings downward so that the sterilization material 63 on the feeding portion can fall into the water storage chamber 11, or the sterilization material 63 on the feeding portion can contact the water in the water storage chamber 11.

[0085] In some other embodiments, the feeding member 310 is movable up and down in the water storage chamber 11. When the water level in the water storage chamber 11 rises, the floating member 320 drives the feeding member 310 to move upward by toggling the first toggle portion 312. At this time, the feeding member 310 opens the feeding port of the storage box 400 so that the sterilization raw material 63 in the storage box 400 can fall into the water storage chamber 11.

[0086] In some specific embodiments of the present invention, Figure 5 As shown, the floating member 320 includes a horizontal rod 321 and a vertical rod 322. At least two opposite side walls of the horizontal rod 321 are slidably matched with the inner wall of the water storage chamber 11. One end of the vertical rod 322 is connected to the horizontal rod 321 and the other end is suitable for matching with the first toggle portion 312. When the water level in the water storage chamber 11 rises, the inner wall of the water storage chamber 11 can limit the movement of the horizontal rod 321 so that the horizontal rod 321 can move upward smoothly, thereby preventing the floating member 320 from tipping over or other displacements, which would affect the matching between the horizontal rod 321 and the first toggle portion 312.

[0087] At the same time, by setting the horizontal rod 321, it is convenient to increase the contact area between the floating member 320 and the water surface in the water storage chamber 11, so as to provide a larger buoyancy for the floating member 320. On the one hand, it can enable the vertical rod 322 to push the first pushing part 312 with a greater force, thereby fully driving the movement of the feeding member 310, so that the feeding member 310 can deliver the sterilization raw material 63 to the water storage chamber 11. On the other hand, it is convenient to ensure that the floating member 320 floats stably on the water surface, so that the floating member 320 can move up or down with the water level, and the floating member 320 will not sink into the water easily.

[0088] In some optional embodiments of the present invention, Figure 1 As shown, the sterilization device 30 is an electrolytic sterilization device 30, and the sterilization device 30 also includes an electrolysis unit 510. The electrolysis unit 510 is arranged in the water storage chamber 11, and is used to electrolyze the solution after the sterilization raw material 63 is added into the water storage chamber 11 to form a sterilization solution, and then use the sterilization solution to sterilize the water in the water storage chamber 11.

[0089] In some embodiments, the main component of the sterilization raw material 63 is sodium chloride. After the sterilization raw material 63 is dissolved in water, the electrolysis unit 510 can electrolyze the solution in the water storage chamber 11 to form hypochlorous acid in the water storage chamber 11, and then the hypochlorous acid can be used to sterilize the water in the water storage chamber 11.

[0090] In some specific embodiments of the present invention, Figure 6 As shown, the sterilization device 30 also includes a switch 520, and the feeding member 310 has a second toggle portion 313. The feeding member 310 drives the switch 520 to close through the second toggle portion 313 to enable the electrolysis unit 510 to work. At this time, the electrolysis unit 510 can ionize the solution in the water storage chamber 11 to form a sterilizable solution in the water storage chamber 11, thereby sterilizing the water in the water storage chamber 11.

[0091] In the process of the feeding drive member driving the feeding member 310 to move, the feeding member 310 can, on the one hand, deliver the sterilization raw material 63 to the water storage chamber 11, and on the other hand, close the switch 520 through the second toggle part 313 to enable the electrolysis unit 510 to ionize the solution in the water storage chamber 11.

[0092] It should be understood that when the feeding drive member drives the feeding member 310 to move, the second toggle portion 313 drives the switch 520 to close and the sterilizing material 63 is delivered to the water storage chamber 11, which can occur simultaneously or successively.

[0093] Specifically, when the feeding drive drives the feeding member 310 to move to a certain position, the feeding member 310 delivers the sterilizing raw material 63 to the water storage chamber 11, and at the same time closes the switch 520 through the second toggle part 313 to open the electrolysis unit 510. Alternatively, the feeding member 310 first delivers the sterilizing raw material 63 to the water storage chamber 11, and the feeding member 310 continues to move for a period of time before closing the switch 520 through the second toggle part 313 to open the electrolysis unit 510; or, the feeding member 310 first closes the switch 520 through the second toggle part 313 to open the electrolysis unit 510, and the feeding member 310 continues to move for a period of time before delivering the sterilizing raw material 63 to the water storage chamber 11.

[0094] like Figure 6 , Figure 7 As shown, in the present embodiment, the feeding driving member is a floating member 320, the feeding member 310 is a rotatable disc-shaped structure, the feeding portion is a feeding trough 311 arranged on the peripheral wall of the feeding member 310, the feeding member 310 has a first toggle portion 312, and the floating member 320 drives the feeding member 310 to rotate by toggling the first toggle portion 312. During the rotation of the feeding member 310, the feeding member 310 can deliver the sterilization raw material 63 in the feeding trough 311 to the water storage chamber 11, and close the switch 520 through the second toggle portion 313 to open the electrolysis unit 510.

[0095] When the water level in the water storage chamber 11 rises, the floating member 320 floats upward, and at the same time, the floating member 320 drives the rotating disk to rotate through the first toggle portion 312. When the water level in the water storage chamber 11 rises to the first water level, the floating member 320 drives the rotating disk to rotate to the first position, and at this time, the sterilization raw material 63 in the feeding trough 311 will fall into the water storage chamber 11 under the action of gravity. When the water level in the water storage chamber 11 rises to the second water level, the floating member 320 drives the rotating disk to rotate to the second position, and at this time, the rotating disk drives the switch 520 to close through the second toggle portion 313 to open the electrolysis unit 510.

[0096] In some embodiments, the first water level and the second water level are the same water level, the first position and the second position are the same position, and when the water level in the water storage chamber 11 rises to the first water level, the feeder 310 feeds the sterilizing raw material 63 into the water storage chamber 11, and at the same time closes the switch 520 through the second toggle portion 313 to turn on the electrolysis unit 510. In other embodiments, the first water level and the second water level are different water levels, and the feeder 310 successively feeds the sterilizing raw material 63 into the water storage chamber 11 in a certain order, and closes the switch 520 through the second toggle portion 313 to turn on the electrolysis unit 510.

[0097] like Figure 5 , Figure 7 As shown, in the present embodiment, the first water level and the second water level are the same water level and are preset water levels, that is, when the water level in the water storage chamber 11 reaches the preset water level, the feeding member 310 delivers the sterilization raw material 63 into the water storage chamber 11, and at the same time, the feeding member 310 closes the switch 520 through the second toggle member, and the electrolysis unit 510 starts to electrolyze the solution in the water storage chamber 11 to form a sterilization solution in the water storage chamber 11, and the water in the water storage chamber 11 is sterilized by the sterilization solution.

[0098] At the same time, when the water level in the water storage chamber 11 reaches the preset water level, at least a portion of the cleaning element is immersed in water, so that the cleaning element can remove dust and hair on the filter 64 while also sterilizing the filter 64, thereby fully cleaning the filter 64 to prevent excessive bacteria from growing on the filter 64. When the user uses the air conditioner 7, the cleanliness of the air outlet of the air conditioner 7 can be improved, thereby improving the user experience.

[0099] In some specific embodiments of the present invention, Figure 6 As shown, the feeding drive member is a floating member 320, and the floating member 320 is arranged in the water storage chamber 11 so as to float up and down according to the water level in the water storage chamber 11. The filter cleaning system 1 also includes a first filter member 61, and the first filter member 61 is arranged in the water storage chamber 11 and is located below the floating member 320 and above the electrolysis unit 510. The first filter member 61 can separate the electrolysis unit 510 and the floating member 320, thereby preventing the floating member 320 from hooking with the electrolysis unit 510 when floating.

[0100] Specifically, when the cleaning element cleans the filter 64, hair debris, dust, etc. on the filter 64 will reach the water storage chamber 11. The first filter element 61 can filter the hair debris and other pollutants in the water storage chamber 11 to prevent the hair debris and other pollutants from adhering to the electrolysis unit 510 and affecting the electrolysis of the solution by the electrolysis unit 510.

[0101] Among them, when the water level in the water storage chamber 11 is lower than the first filter element 61, the floating member 320 can be supported on the first filter element 61 to limit the movable range of the floating member 320, so as to ensure the stability of the cooperation between the floating member 320 and the feeding member 310, and avoid the floating member 320 from being stuck at a certain position in the water storage chamber 11, so as to ensure that the floating member 320 can stably drive the feeding member 310 to move.

[0102] In some examples, such as Figure 2 As shown, the feeding member 310 is formed as a rotatable disc structure, and a feeding groove 311 is provided on the circumference of the feeding member 310. The feeding member 310 also has a first toggle portion 312. When the floating member 320 is supported on the first filter element 61, the top of the floating member 320 is supported and cooperated with the first toggle portion 312 to limit the position of the feeding member 310, so that the feeding groove 311 on the feeding member 310 can stop against the bottom of the storage box 400, and then the sterilization material 63 in the storage box 400 can smoothly reach the feeding groove 311.

[0103] When the water level in the water storage chamber 11 gradually rises, the floating member 320 drives the feeding member 310 to rotate through the first driving portion 312 . When the feeding member 310 rotates, the feeding trough 311 rotates around its rotation center and delivers the sterilization material 63 therein to the water storage chamber 11 .

[0104] In some optional embodiments of the present invention, Figure 5 As shown, at least a portion of the bottom wall of the storage box 400 or a guide surface 410 is provided between the storage box 400 and the feeding member 310. The guide surface 410 extends downwardly along a direction close to the feeding member 310 to guide the sterilization material 63 in the storage box 400 to the feeding part by gravity, and then when the feeding drive member drives the feeding member 310 to move, the feeding member 310 can deliver the sterilization material 63 to the water storage chamber 11.

[0105] In some embodiments, the bottom wall of the material storage box 400 is a guide surface 410, the end of the guide surface 410 cooperates with the feeding part, and the material storage box 400 has a feeding port on the side away from the feeding part, and the guide surface 410 extends downwardly and tilted toward the feeding member 310, and the sterilizing raw material 63 can be added to the material storage box 400 from the feeding port. Under the action of gravity, the sterilizing raw material 63 can flow along the guide surface 410 to the feeding part, and when the feeding drive member drives the feeding member 310 to move, the feeding member 310 can deliver the sterilizing raw material 63 to the water storage chamber 11.

[0106] In other embodiments, a guide surface 410 is provided between the material storage box 400 and the feeding piece 310. The material storage box 400 is pullable and arranged on the shell 10. When it is necessary to replenish the sterilization raw materials 63, the material storage box 400 can be pulled to replenish the sterilization raw materials 63 into the material storage box 400. The sterilization raw materials 63 in the material storage box 400 can flow along the guide surface 410 to the feeding piece 310. When the feeding drive member drives the feeding piece 310 to move, the feeding piece 310 can deliver the sterilization raw materials 63 to the water storage chamber 11.

[0107] In some embodiments of the present invention, a drain outlet is provided at the bottom of the water storage chamber 11, and a second filter element is provided at the drain outlet. After the cleaning element completes cleaning the filter 64, the water in the water storage chamber 11 can be discharged from the drain outlet, and pollutants such as hair debris in the water will be collected by the second filter element to prevent pollutants such as hair debris from clogging the drain outlet.

[0108] A specific embodiment of the filter cleaning system 1 according to the present invention is described below with reference to the accompanying drawings. The filter cleaning system 1 includes a housing 10 , a cleaning device and a sterilizing device 30 .

[0109] like Figure 1 , Fig.11 As shown, the housing 10 defines a water storage chamber 11, which includes a first chamber 111 and a second chamber 112 that are connected. The sterilization device 30 includes a feeding member 310, a floating member 320, a storage box 400 and an electrolysis unit 510. The floating member 320 is arranged in the first chamber 111. When the water level in the first chamber 111 rises, the floating member 320 will move upward. The feeding member 310 is formed into a rotatable disc structure. There is a feeding trough 311, and the storage box 400 is arranged on one side of the feeding piece 310. At least a part of the bottom wall of the storage box 400 or a guide surface 410 is provided between the storage box 400 and the feeding piece 310. Under the action of gravity, the sterilization material 63 in the storage box 400 can fall into the feeding trough 311 along the guide surface 410. The feeding piece 310 also has a first toggle part 312, and the floating part 320 drives the feeding piece 310 to rotate by toggling the first toggle part 312.

[0110] Among them, a first filter element 61 is provided in the first chamber 111, a floating member 320 is provided above the first filter element 61, and an electrolysis unit 510 is provided below the first filter element 61. When the water level in the first chamber 111 is lower than the first filter element 61, the floating member 320 is supported on the first filter element 61. At this time, the top of the floating member 320 is supported and cooperated with the first toggle portion 312 to limit the position of the feeding member 310, so that the feeding trough 311 can stop against the end of the guide surface 410, so that the sterilization raw material 63 in the storage box 400 can smoothly reach the feeding trough 311.

[0111] When the water level in the first chamber 111 gradually rises, the floating member 320 moves upward, and the floating member 320 drives the feeding member 310 to rotate through the first driving part 312. When the feeding member 310 rotates, the feeding trough 311 rotates clockwise and downward around its rotation center. When the water level in the first chamber 111 reaches the preset water level, the feeding member 310 delivers the sterilization material 63 in the feeding trough 311 to the water storage chamber 11.

[0112] The sterilization device 30 also includes a switch 520, which is used to control the electrolysis unit 510. The switch 520 is arranged on one side of the feeding piece 310, and the feeding piece 310 is provided with a second toggle portion 313. When the floating piece 320 moves upward and the floating piece 320 drives the feeding piece 310 to rotate clockwise through the first toggle portion 312, the feeding piece 310 drives the second toggle portion 313 to rotate, and the second toggle portion 313 rotates in a direction close to the switch 520. When the water level in the first chamber 111 reaches the preset water level, the second toggle portion 313 closes the switch 520, and the electrolysis unit 510 starts working.

[0113] That is, when the sterilizing raw material 63 is delivered to the water storage chamber 11 , the electrolysis unit 510 also starts to work, so that the electrolysis unit 510 can ionize the solution in the water storage chamber 11 to sterilize the water in the water storage chamber 11 .

[0114] The cleaning device includes a cleaning member, which is disposed in the second chamber 112 . The cleaning member includes a rotating portion 211 and a brush (not shown in the figure). When the rotating portion 211 rotates, the brush can be driven to rotate, and the brush can clean the filter 64 .

[0115] A drain outlet is provided at the bottom of the second chamber 112, and a second filter element is provided at the drain outlet. After the cleaning element completes cleaning of the filter screen 64, the water in the water storage chamber 11 can be discharged from the drain outlet, and pollutants such as hair debris in the water will be collected by the second filter element to prevent pollutants such as hair debris from clogging the drain outlet.

[0116] Next, the air conditioner 7 according to the embodiment of the present invention will be described.

[0117] like Fig.11 , Fig.13 As shown, the air conditioner 7 according to the embodiment of the present invention comprises an air conditioner body 70 , a filter driving assembly 80 , the filter cleaning system 1 of the air conditioner according to the above-mentioned embodiment of the present invention, and a water pump 91 .

[0118] The air conditioner body 70 has an air inlet 71, and a movable filter 64 is provided at the air inlet 71. The filter 64 can filter the air entering the air conditioner body 70 to ensure the cleanliness of the incoming air, prevent unclean air from polluting the environment inside the air conditioner body 70, and prevent the air conditioner body 70 from introducing unclean air into the room.

[0119] The filter driving assembly 80 is disposed on the air conditioner body 70, and the filter driving assembly 80 is connected to the filter 64. The filter driving assembly 80 is used to drive the filter 64 to move. The filter cleaning system 1 is disposed on one side of the filter 64. When the filter 64 moves, the filter 64 and the cleaning part move relative to each other so that the cleaning part can fully clean the filter 64.

[0120] At the same time, when the filter driving assembly 80 drives the filter 64 to move, the hair and dust on the filter 64 will fall off the filter 64 to perform preliminary cleaning on the filter 64.

[0121] The water pump 91 is used to transport the water in the water receiving tray of the air conditioner body 70 to the water storage chamber 11 to replenish the water in the water storage chamber 11, so that the water level in the water storage chamber 11 can reach a preset water level, so that the water in the water storage chamber 11 can immerse at least a part of the cleaning part, and the cleaning part can use the water in the water storage chamber 11 to fully clean the filter 64.

[0122] According to the air conditioner 7 of the embodiment of the present invention, by utilizing the filter cleaning system 1 of the air conditioner according to the above-mentioned embodiment of the present invention, the water in the water storage chamber 11 is sterilized by utilizing the sterilization device 30. By sterilizing the water in the water storage chamber 11, the cleaning part can also sterilize the filter 64 when using the water in the water storage chamber 11 to clean the filter 64, thereby reducing the bacteria breeding on the filter 64 and improving the cleanliness of the air outlet of the air conditioner 7.

[0123] In some embodiments of the present invention, Fig.11 As shown, the filter driving assembly 80 is rotatably disposed on one side of the length direction of the filter 64 and meshed with the filter 64. The cleaning member is located on the peripheral side of the filter driving assembly 80 to clean the filter 64 covering the filter driving assembly 80. When the filter driving assembly 80 rotates, the filter driving assembly 80 can drive the filter 64 to move. At this time, the cleaning member can clean the filter 64 clamped between the cleaning member and the filter driving assembly 80.

[0124] Specifically, the cleaning member can clean the portion of the filter 64 sandwiched between the filter drive assembly 80 and the cleaning member. With the support of the filter drive assembly 80, the cleaning member can apply a certain force to the filter 64 so that the cleaning member can fully clean this portion of the filter 64. At the same time, under the drive of the filter drive assembly 80, the filter 64 can move relative to the cleaning member so that the cleaning member can fully clean all areas of the filter 64.

[0125] In some embodiments of the present invention, the rotation axis of the cleaning member is parallel to the rotation axis of the filter drive assembly 80. This arrangement facilitates increasing the contact area between the cleaning member and the filter 64, so that when the filter drive assembly 80 drives the filter 64 to move, the cleaning member can fully clean the filter 64.

[0126] A specific implementation of the air conditioner 7 according to an embodiment of the present invention is described below:

[0127] like Figure 1 , Fig.11 , Fig.13 As shown, the air conditioner 7 according to the embodiment of the present invention includes an air conditioner body 70, a filter 64, a filter driving assembly 80, a water pump 91 and a filter cleaning system 1.

[0128] The air conditioner body 70 has an air inlet 71, a filter 64 is disposed at the air inlet 71, the filter 64 extends in the left-right direction, a filter driving assembly 80 is disposed at the left end of the filter 64, and the filter driving assembly 80 can drive the filter 64 to move from the left end of the filter 64. The filter cleaning system 1 is disposed on the left side of the air conditioner body 70, and the filter cleaning system 1 includes a housing 10, a cleaning device, and a sterilizing device 30.

[0129] The housing 10 defines a water storage chamber 11, which includes a first chamber 111 and a second chamber 112 that are connected. The sterilizing device 30 includes a feeding member 310, a floating member 320, a storage box 400 and an electrolytic unit 510. The floating member 320 is arranged in the first chamber 111. When the water level in the first chamber 111 rises, the floating member 320 will move upward. The feeding member 310 is formed into a rotatable disc structure. The feeding member 310 is provided with a feeding member 310 on its circumference. The material trough 311 and the material storage box 400 are arranged on one side of the feeding piece 310. At least a part of the bottom wall of the material storage box 400 or a guide surface 410 is provided between the material storage box 400 and the feeding piece 310. Under the action of gravity, the sterilization material 63 in the material storage box 400 can fall into the feeding trough 311 along the guide surface 410. The feeding piece 310 also has a first toggle part 312. The floating part 320 drives the feeding piece 310 to rotate by toggling the first toggle part 312.

[0130] Among them, a first filter element 61 is provided in the first chamber 111, a floating member 320 is provided above the first filter element 61, and an electrolysis unit 510 is provided below the first filter element 61. When the water level in the first chamber 111 is lower than the first filter element 61, the floating member 320 is supported on the first filter element 61. At this time, the top of the floating member 320 is supported and cooperated with the first toggle portion 312 to limit the position of the feeding member 310, so that the feeding trough 311 can stop against the end of the guide surface 410, so that the sterilization raw material 63 in the storage box 400 can smoothly reach the feeding trough 311.

[0131] The water pump 91 is used to transport the water in the water receiving tray of the air conditioner body 70 to the water storage chamber 11 to replenish the water storage chamber 11. When the water pump 91 pumps the water in the water receiving tray into the water storage chamber 11, the water level in the first chamber 111 gradually rises, and the floating member 320 moves upward. The floating member 320 drives the feeding member 310 to rotate through the first toggle portion 312. When the feeding member 310 rotates, the feeding trough 311 rotates clockwise and downward around its rotation center. When the water level in the first chamber 111 reaches a preset water level, the feeding member 310 delivers the sterilization material 63 in the feeding trough 311 to the water storage chamber 11.

[0132] The sterilization device 30 also includes a switch 520, which is used to control the electrolysis unit 510. The switch 520 is arranged on one side of the feeding piece 310, and the feeding piece 310 is provided with a second toggle portion 313. When the floating piece 320 moves upward and the floating piece 320 drives the feeding piece 310 to rotate clockwise through the first toggle portion 312, the feeding piece 310 drives the second toggle portion 313 to rotate, and the second toggle portion 313 rotates in a direction close to the switch 520. When the water level in the first chamber 111 reaches the preset water level, the second toggle portion 313 closes the switch 520, and the electrolysis unit 510 starts working.

[0133] That is, when the sterilizing raw material 63 is delivered to the water storage chamber 11 , the electrolysis unit 510 also starts to work, so that the electrolysis unit 510 can ionize the solution in the water storage chamber 11 to sterilize the water in the water storage chamber 11 .

[0134] The cleaning device includes a cleaning piece, which is arranged in the second chamber 112. The cleaning piece includes a rotating part 211 and a brush (not shown in the figure). When the rotating part 211 rotates, it can drive the brush to rotate, and the brush can clean the filter 64. The filter drive assembly 80 is arranged above the second chamber 112, above the cleaning piece.

[0135] The axis of the cleaning member extends in the front-to-back direction, and the axis of the filter driving assembly 80 also extends in the front-to-back direction (it should be understood here that the above-mentioned direction limitation is only for the convenience of describing the accompanying drawings and will not limit the actual setting position and direction of the air conditioner 7). When the water level in the second chamber 112 reaches the preset water level, a part below the cleaning member is immersed in water. At this time, the filter driving assembly 80 rotates to drive the filter 64 to move relative to the cleaning member. When the cleaning member rotates, the filter 64 can be cleaned.

[0136] Among them, the filter driving assembly 80 and the cleaning member can rotate in different directions, or rotate in the same direction at different speeds. When the filter driving assembly 80 drives the filter 64 to move, the hair and dust on the filter 64 will fall off the filter 64 to perform preliminary cleaning on the filter 64, and the hair and dust on the filter 64 will fall into the second chamber 112.

[0137] A drain outlet is provided at the bottom of the second chamber 112, and a second filter element is provided at the drain outlet. After the cleaning element completes cleaning of the filter screen 64, the water in the water storage chamber 11 can be discharged from the drain outlet, and pollutants such as hair debris in the water will be collected by the second filter element to prevent pollutants such as hair debris from clogging the drain outlet.

[0138] The following describes a method for controlling the air conditioner 7 according to an embodiment of the present invention.

[0139] like Figure 1 , Fig.11 , Fig.13 As shown, the air conditioner 7 includes an air conditioner body 70 , a filter driving assembly 80 , a water pump 91 and a filter cleaning system 1 .

[0140] The filter driving assembly 80 is used to drive the filter 64 of the air conditioner body 70 to move. The filter cleaning system 1 has a water storage chamber 11. The water pump 91 is used to transport the water in the water receiving tray of the air conditioner body 70 to the water storage chamber 11. The filter cleaning system 1 includes a cleaning device and a sterilizing device 30. The cleaning device includes a rotatable cleaning part. The cleaning part is used to clean the filter 64. The sterilizing device 30 is used to sterilize the water in the water storage chamber 11. The cleaning part can use the water in the water storage chamber 11 to sterilize the filter 64, so as to sterilize the filter 64 while cleaning the dander, dust and other pollutants on the filter 64.

[0141] Among them, Fig.14 As shown, the control method of the air conditioner 7 according to the embodiment of the present invention includes the following control steps:

[0142] S1: Obtaining a cleaning instruction and detecting the water level in the water storage chamber 11;

[0143] S21: Determine that the water level in the water storage chamber 11 reaches a preset water level, and detect the on / off state of the switch 520 of the sterilization device 30;

[0144] S31: Determine that the switch 520 of the sterilization device 30 is closed, control the water pump 91 to be closed, and control the sterilization device 30 to work for a first preset time;

[0145] S4: Control the cleaning device and the filter driving assembly 80 to work.

[0146] Specifically, after the user applies an instruction and the air conditioner 7 obtains the cleaning instruction, it first detects the water level in the water storage chamber 11; when it detects that the water level in the water storage chamber 11 reaches the preset water level; detects the open and closed state of the switch 520, and after determining that the switch 520 of the sterilization device 30 is closed; controls the water pump 91 to turn off, and then controls the sterilization device 30 to work for the first preset time, at which time the sterilization device 30 fully sterilizes the water in the water storage chamber 11; then controls the cleaning device and the filter drive assembly 80 to work, the filter drive assembly 80 drives the filter 64 to move, and the cleaning device can clean the filter 64.

[0147] According to the control method of the air conditioner 7 in the embodiment of the present invention, the cleaning member is controlled to clean the filter 64, so that the sterilization device 30 sterilizes the water in the water storage chamber 11. By sterilizing the water in the water storage chamber 11, the cleaning member can also sterilize the filter 64 when using the water in the water storage chamber 11 to clean the filter 64, thereby reducing the bacteria grown on the filter 64 and improving the cleanliness of the air outlet of the air conditioner 7.

[0148] In some embodiments of the present invention, Fig.15 As shown, after obtaining the cleaning instruction, it also includes S22: determining that the water level in the water storage chamber 11 is lower than the preset water level, and controlling the water pump 91 to work so that the water level in the water storage chamber 11 reaches the preset water level.

[0149] Specifically, after the user applies an instruction and the air conditioner 7 obtains the cleaning instruction, it first detects the water level in the water storage chamber 11; when it is detected that the water level in the water storage chamber 11 is lower than the preset water level, the water pump 91 is controlled to work, and the water pump 91 transfers the water in the water receiving tray to the water storage chamber 11 to increase the amount of water in the water storage chamber 11; when it is detected that the water level in the water storage chamber 11 reaches the preset water level, the open and closed state of the switch 520 of the sterilization device 30 is detected; after determining that the switch 520 of the sterilization device 30 is closed, the water pump 91 is controlled to be closed, and water is no longer replenished to the water storage chamber 11.

[0150] Then the sterilization device 30 is controlled to work for the first preset time, at which time the sterilization device 30 sterilizes the water in the water storage chamber 11; then the cleaning device and the filter driving assembly 80 are controlled to work, the filter driving assembly 80 drives the filter 64 to move, and the cleaning device can clean the filter 64.

[0151] In some optional embodiments of the present invention, when the working time of the water pump 91 reaches a second preset time and the water level in the water storage chamber 11 is lower than a preset water level, the air conditioner 7 is controlled to issue a first alarm message.

[0152] Specifically, after the user issues an instruction and the air conditioner 7 obtains the cleaning instruction, it first detects the water level in the water storage chamber 11; when it detects that the water level in the water storage chamber 11 is lower than the preset water level; it controls the water pump 91 to work, and the water pump 91 transports the water in the water receiving tray to the water storage chamber 11, so that the water level in the water storage chamber 11 reaches the preset water level. After the water pump 91 continues to work for a second preset time, when the water level in the water storage chamber 11 is still lower than the preset water level; it controls the air conditioner 7 to issue a first alarm message to remind the user to repair the air conditioner. At this time, the air conditioner 7 cannot clean the filter 64 normally.

[0153] In some embodiments, the water level in the water storage chamber 11 can be continuously detected. Once it is detected that the water level in the water storage chamber 11 reaches a preset water level, the on / off state of the switch 520 of the electrolysis unit 510 is detected. If the switch 520 of the electrolysis unit 510 is closed, the water pump 91 is controlled to stop working. If the water level in the water storage chamber 11 is still lower than the preset water level after the water pump 91 continues to work for a second preset time, an alarm is required to remind the user.

[0154] In other embodiments, the water level in the water storage chamber 11 is detected every T time. When the water level in the water storage chamber 11 is initially detected to be lower than a preset water level, the water pump 91 works for T time. At this time, the water level in the water storage chamber 11 is detected again. If the water level in the water storage chamber 11 reaches the preset water level, the on / off state of the switch 520 of the electrolysis unit 510 is detected. If the switch 520 of the electrolysis unit 510 is closed, the water pump 91 is controlled to stop working.

[0155] If the water level in the water storage chamber 11 has not reached the preset water level at this time, the water pump 91 works again for T time, and the water level in the water storage chamber 11 is detected again at this time; if the water level in the water storage chamber 11 reaches the preset water level at this time, the open and closed state of the switch 520 of the electrolysis unit 510 is detected; if the switch 520 of the electrolysis unit 510 is closed, the water pump 91 is controlled to stop working.

[0156] If the water level in the water storage chamber 11 has not reached the preset water level after the water pump 91 works again for T time, the air conditioner 7 is controlled to send out a first alarm message to remind the user to repair the air conditioner. At this time, the air conditioner 7 cannot clean the filter 64 normally. Here 2T is the second preset time.

[0157] In some embodiments, the water in the water receiving tray is condensed water generated when the air conditioner 7 is cooling, and the condensed water will collect in the water receiving tray. The second preset time can be 30 minutes, 1 hour, 2 hours or 3 hours, which can be determined according to the local humidity environment. After the air conditioner 7 works for the second preset time, it should be sufficient to generate enough water to make the water storage chamber 11 reach the preset water level.

[0158] If the water pump 91 continues to work for the second preset time and the water in the water storage chamber 11 has not reached the preset water level, it may be that the refrigeration function of the air conditioner 7 fails and cannot store enough condensed water in the water receiving tray. It may also be that the water pump 91 fails. Therefore, the air conditioner 7 needs to issue a first alarm message to remind the user.

[0159] In some embodiments, the first alarm message may be to remind the user through video or picture, or may be to remind the user through sound, light signal or other means.

[0160] In some optional embodiments of the present invention, after determining that the water level in the water storage chamber 11 reaches the preset water level, it also includes S32: determining that the switch 520 of the sterilization device 30 is turned on, and controlling the air conditioner 7 to issue a second alarm message.

[0161] Specifically, after the user applies an instruction and the air conditioner 7 obtains the cleaning instruction, it first detects the water level in the water storage chamber 11; when it is detected that the water level in the water storage chamber 11 reaches the preset water level, the on / off state of the switch 520 of the sterilization device 30 is detected; after determining that the switch 520 of the sterilization device 30 is turned on, the air conditioner 7 is controlled to issue a second alarm message; at this time, the sterilization device 30 is not turned on, and the solution in the water storage chamber 11 cannot be ionized, and the water in the water storage chamber 11 cannot be sterilized. At this time, a second alarm message can be issued to remind the user that the water in the water storage chamber 11 cannot be sterilized, thereby reminding the user to perform repairs in time.

[0162] In some embodiments, the second alarm message can be a video or picture to remind the user, or a sound, light signal or other method to remind the user.

[0163] A specific embodiment of the air conditioner 7 and the control method of the air conditioner 7 of the present invention is described below with reference to the accompanying drawings:

[0164] like Figure 1 , Fig.11 , Fig.13 As shown, the air conditioner 7 includes an air conditioner body 70, a filter 64, a filter driving assembly 80, a water pump 91 and a filter cleaning system 1.

[0165] The air conditioner body 70 has an air inlet 71, a filter 64 is disposed at the air inlet 71, the filter 64 extends in the left-right direction, a filter driving assembly 80 is disposed at the left end of the filter 64, and the filter driving assembly 80 can drive the filter 64 to move from the left end of the filter 64. The filter cleaning system 1 is disposed on the left side of the air conditioner body 70, and the filter cleaning system 1 includes a housing 10, a cleaning device, and a sterilizing device 30.

[0166] The housing 10 defines a water storage chamber 11, which includes a first chamber 111 and a second chamber 112 that are connected. The sterilizing device 30 includes a feeding member 310, a floating member 320, a storage box 400 and an electrolytic unit 510. The floating member 320 is arranged in the first chamber 111. When the water level in the first chamber 111 rises, the floating member 320 will move upward. The feeding member 310 is formed into a rotatable disc structure. The feeding member 310 is provided with a feeding member 310 on its circumference. The material trough 311 and the material storage box 400 are arranged on one side of the feeding piece 310. At least a part of the bottom wall of the material storage box 400 or a guide surface 410 is provided between the material storage box 400 and the feeding piece 310. Under the action of gravity, the sterilization material 63 in the material storage box 400 can fall into the feeding trough 311 along the guide surface 410. The feeding piece 310 also has a first toggle part 312. The floating part 320 drives the feeding piece 310 to rotate by toggling the first toggle part 312.

[0167] Among them, a first filter element 61 is provided in the first chamber 111, a floating member 320 is provided above the first filter element 61, and an electrolysis unit 510 is provided below the first filter element 61. When the water level in the first chamber 111 is lower than the first filter element 61, the floating member 320 is supported on the first filter element 61. At this time, the top of the floating member 320 is supported and cooperated with the first toggle portion 312 to limit the position of the feeding member 310, so that the feeding trough 311 can stop against the end of the guide surface 410, so that the sterilization raw material 63 in the storage box 400 can smoothly reach the feeding trough 311.

[0168] The water pump 91 is used to transport the water in the water receiving tray of the air conditioner body 70 to the water storage chamber 11 to replenish the water storage chamber 11. When the water pump 91 pumps the water in the water receiving tray into the water storage chamber 11, the water level in the first chamber 111 gradually rises, and the floating member 320 moves upward. The floating member 320 drives the feeding member 310 to rotate through the first toggle portion 312. When the feeding member 310 rotates, the feeding trough 311 rotates clockwise and downward around its rotation center. When the water level in the first chamber 111 reaches a preset water level, the feeding member 310 delivers the sterilization material 63 in the feeding trough 311 to the water storage chamber 11.

[0169] The sterilization device 30 also includes a switch 520, which is used to control the electrolysis unit 510. The switch 520 is arranged on one side of the feeding piece 310, and the feeding piece 310 is provided with a second toggle portion 313. When the floating piece 320 moves upward and the floating piece 320 drives the feeding piece 310 to rotate clockwise through the first toggle portion 312, the feeding piece 310 drives the second toggle portion 313 to rotate, and the second toggle portion 313 rotates in a direction close to the switch 520. When the water level in the first chamber 111 reaches the preset water level, the second toggle portion 313 closes the switch 520, and the electrolysis unit 510 starts working.

[0170] That is, when the sterilizing raw material 63 is delivered to the water storage chamber 11 , the electrolysis unit 510 also starts to work, so that the electrolysis unit 510 can ionize the solution in the water storage chamber 11 to sterilize the water in the water storage chamber 11 .

[0171] The cleaning device includes a cleaning piece, which is arranged in the second chamber 112. The cleaning piece includes a rotating part 211 and a brush (not shown in the figure). When the rotating part 211 rotates, it can drive the brush to rotate, and the brush can clean the filter 64. The filter drive assembly 80 is arranged above the second chamber 112, above the cleaning piece.

[0172] The axis of the cleaning member extends in the front-to-back direction, and the axis of the filter driving assembly 80 also extends in the front-to-back direction. When the water level in the second chamber 112 reaches the preset water level, a portion below the cleaning member is immersed in water. At this time, the filter driving assembly 80 rotates to drive the filter 64 to move relative to the cleaning member. When the cleaning member rotates, the filter 64 can be cleaned.

[0173] Among them, the filter driving assembly 80 and the cleaning member can rotate in different directions or in the same direction at different speeds. When the filter driving assembly 80 drives the filter 64 to move, the hair and dust on the filter 64 will fall off the filter 64 to perform preliminary cleaning on the filter 64, and the hair and dust on the filter 64 will fall into the second chamber 112.

[0174] A drain outlet is provided at the bottom of the second chamber 112, and a second filter element is provided at the drain outlet. After the cleaning element completes cleaning of the filter screen 64, the water in the water storage chamber 11 can be discharged from the drain outlet, and pollutants such as hair debris in the water will be collected by the second filter element to prevent pollutants such as hair debris from clogging the drain outlet.

[0175] When the cleaning element is controlled by the controller of the air conditioner 7 to clean the filter 64, three results will be produced:

[0176] Result 1, such as Fig.14 , Fig.15 As shown:

[0177] S1: Obtaining a cleaning instruction and detecting the water level in the water storage chamber 11;

[0178] S21: Determine that the water level in the water storage chamber 11 reaches a preset water level, and detect the on / off state of the switch 520 of the sterilization device 30;

[0179] S31: Determine that the switch 520 of the sterilization device 30 is closed, control the water pump 91 to be closed, and control the sterilization device 30 to work for a first preset time;

[0180] S4: Control the cleaning device and the filter driving assembly 80 to work.

[0181] or,

[0182] S1: Obtaining a cleaning instruction and detecting the water level in the water storage chamber 11;

[0183] S22: Determine that the water level in the water storage chamber 11 is lower than a preset water level, and control the water pump 91 to operate so that the water level in the water storage chamber 11 reaches the preset water level;

[0184] S21: Determine that the water level in the water storage chamber 11 reaches a preset water level, and detect the on / off state of the switch 520 of the sterilization device 30;

[0185] S31: Determine that the switch 520 of the sterilization device 30 is closed, control the water pump 91 to be closed, and control the sterilization device 30 to work for a first preset time;

[0186] S4: Control the cleaning device and the filter driving assembly 80 to work.

[0187] Result 2:

[0188] S1: Obtaining a cleaning instruction and detecting the water level in the water storage chamber 11;

[0189] S22: Determine that the water level in the water storage chamber 11 is lower than a preset water level, and control the water pump 91 to operate so that the water level in the water storage chamber 11 reaches the preset water level;

[0190] When the working time of the water pump 91 reaches the second preset time and the water level in the water storage chamber 11 is lower than the preset water level, the air conditioner 7 is controlled to issue a first alarm message.

[0191] Result three, such as Fig.16 As shown:

[0192] S1: Obtaining a cleaning instruction and detecting the water level in the water storage chamber 11;

[0193] S21: Determine that the water level in the water storage chamber 11 reaches a preset water level, and detect the on / off state of the switch 520 of the sterilization device 30;

[0194] S32: Determine that the switch 520 of the sterilization device 30 is turned on, and control the air conditioner 7 to issue a second alarm message.

[0195] It should be explained here that when it is determined that the water level in the water storage chamber 11 reaches the preset water level, the water pump 91 may work for a period of time before the water level in the water storage chamber 11 reaches the preset water level, which will not be repeated here.

[0196] Next, the air conditioner 7 according to the embodiment of the present invention will be described.

[0197] like Figure 1 , Fig.11 , Fig.13 , Fig.17As shown, the air conditioner 7 according to the embodiment of the present invention includes an air conditioner body 70, a filter drive assembly 80, a filter cleaning system 1, a water pump 91, a water level detection component 72, an acquisition assembly 73 and a control device 74. The air conditioner body 70 has an air inlet 71, and a movable filter 64 is provided at the air inlet 71. The filter drive assembly 80 is arranged on the air conditioner body 70 and connected to the filter 64. The filter drive assembly 80 is used to drive the filter 64 to move.

[0198] The filter cleaning system 1 has a water storage chamber 11, and the filter cleaning system 1 includes a cleaning device and a sterilizing device 30. The cleaning device includes a rotatable cleaning part, and the cleaning part is used to clean the filter 64. The water pump 91 is used to transport the water in the water receiving tray of the air conditioner body 70 to the water storage chamber 11 to replenish the water in the water storage chamber 11. The sterilizing device 30 is used to sterilize the water in the water storage chamber 11, so that the cleaning part can use the water in the water storage chamber 11 to sterilize the filter 64, so as to sterilize the filter 64 while cleaning the dander, dust and other pollutants on the filter 64.

[0199] The water level detection component 72 is used to detect the water level in the water storage chamber 11, and the acquisition component 73 is used to obtain the detection result of the water level detection component 72. The control device 74 communicates with the water level detection component 72. After the acquisition component 73 acquires the detection structure of the water level detection component 72, the acquisition component 73 transmits the water level information in the water storage chamber 11 to the control device 74.

[0200] The control device 74 also communicates with the switch 520 of the sterilization device 30, the cleaning device and the filter drive assembly 80. When the water level detection component 72 detects that the water level in the water storage chamber 11 reaches the preset water level and the switch 520 of the sterilization device 30 is closed, the control device 74 controls the water pump 91 to turn off and controls the sterilization device 30 to work for the first preset time. After the sterilization device 30 stops working, the control device 74 also controls the cleaning device and the filter drive assembly 80 to work.

[0201] At this time, the sterilization device 30 has sterilized the water in the water storage chamber 11. After the sterilization device 30 stops working, the control device 74 controls the cleaning device and the filter drive assembly 80 to work. At this time, the filter drive assembly 80 drives the filter 64 to move, and the cleaning component can clean and sterilize the filter 64.

[0202] According to the air conditioner 7 of the embodiment of the present invention, the sterilization device 30 is used to sterilize the water in the water storage chamber 11. By sterilizing the water in the water storage chamber 11, the cleaning part can also sterilize the filter 64 when using the water in the water storage chamber 11 to clean the filter 64, thereby reducing the bacteria growing on the filter 64 and improving the cleanliness of the air outlet of the air conditioner 7.

[0203] In some embodiments of the present invention, when the water level detection component 72 detects that the water level in the water storage chamber 11 is lower than a preset water level, the control device 74 controls the water pump 91 to operate so that the water level in the water storage chamber 11 reaches the preset water level, so as to provide sufficient water for the cleaning component, so that the cleaning component can fully clean the filter screen 64 and use the sterilized water to sterilize the filter screen 64.

[0204] A specific embodiment of the air conditioner 7 according to the embodiment of the present invention is described below.

[0205] like Figure 1 , Fig.11 , Fig.13 As shown, the air conditioner 7 includes an air conditioner body 70, a filter 64, a filter driving assembly 80, a water pump 91 and a filter cleaning system 1.

[0206] The air conditioner body 70 has an air inlet 71, a filter 64 is disposed at the air inlet 71, the filter 64 extends in the left-right direction, a filter driving assembly 80 is disposed at the left end of the filter 64, and the filter driving assembly 80 can drive the filter 64 to move from the left end of the filter 64. The filter cleaning system 1 is disposed on the left side of the air conditioner body 70, and the filter cleaning system 1 includes a housing 10, a cleaning device, and a sterilizing device 30.

[0207] The housing 10 defines a water storage chamber 11, which includes a first chamber 111 and a second chamber 112 that are connected. The sterilizing device 30 includes a feeding member 310, a floating member 320, a storage box 400 and an electrolytic unit 510. The floating member 320 is arranged in the first chamber 111. When the water level in the first chamber 111 rises, the floating member 320 will move upward. The feeding member 310 is formed into a rotatable disc structure. The feeding member 310 is provided with a feeding member 310 on its circumference. The material trough 311 and the material storage box 400 are arranged on one side of the feeding piece 310. At least a part of the bottom wall of the material storage box 400 or a guide surface 410 is provided between the material storage box 400 and the feeding piece 310. Under the action of gravity, the sterilization material 63 in the material storage box 400 can fall into the feeding trough 311 along the guide surface 410. The feeding piece 310 also has a first toggle part 312. The floating part 320 drives the feeding piece 310 to rotate by toggling the first toggle part 312.

[0208] Among them, a first filter element 61 is provided in the first chamber 111, a floating member 320 is provided above the first filter element 61, and an electrolysis unit 510 is provided below the first filter element 61. When the water level in the first chamber 111 is lower than the first filter element 61, the floating member 320 is supported on the first filter element 61. At this time, the top of the floating member 320 is supported and cooperated with the first toggle portion 312 to limit the position of the feeding member 310, so that the feeding trough 311 can stop against the end of the guide surface 410, so that the sterilization raw material 63 in the storage box 400 can smoothly reach the feeding trough 311.

[0209] The water pump 91 is used to transport the water in the water receiving tray of the air conditioner body 70 to the water storage chamber 11 to replenish the water storage chamber 11. When the water pump 91 pumps the water in the water receiving tray into the water storage chamber 11, the water level in the first chamber 111 gradually rises, and the floating member 320 moves upward. The floating member 320 drives the feeding member 310 to rotate through the first toggle portion 312. When the feeding member 310 rotates, the feeding trough 311 rotates clockwise and downward around its rotation center. When the water level in the first chamber 111 reaches a preset water level, the feeding member 310 delivers the sterilization material 63 in the feeding trough 311 to the water storage chamber 11.

[0210] The sterilization device 30 also includes a switch 520, which is used to control the electrolysis unit 510. The switch 520 is arranged on one side of the feeding piece 310, and the feeding piece 310 is provided with a second toggle portion 313. When the floating piece 320 moves upward and the floating piece 320 drives the feeding piece 310 to rotate clockwise through the first toggle portion 312, the feeding piece 310 drives the second toggle portion 313 to rotate, and the second toggle portion 313 rotates in a direction close to the switch 520. When the water level in the first chamber 111 reaches the preset water level, the second toggle portion 313 closes the switch 520, and the electrolysis unit 510 starts working.

[0211] That is, when the sterilizing raw material 63 is delivered to the water storage chamber 11 , the electrolysis unit 510 also starts to work, so that the electrolysis unit 510 can ionize the solution in the water storage chamber 11 to sterilize the water in the water storage chamber 11 .

[0212] The cleaning device includes a cleaning piece, which is arranged in the second chamber 112. The cleaning piece includes a rotating part 211 and a brush (not shown in the figure). When the rotating part 211 rotates, it can drive the brush to rotate, and the brush can clean the filter 64. The filter drive assembly 80 is arranged above the second chamber 112, above the cleaning piece.

[0213] The axis of the cleaning member extends in the front-to-back direction, and the axis of the filter driving assembly 80 also extends in the front-to-back direction. When the water level in the second chamber 112 reaches the preset water level, a portion below the cleaning member is immersed in water. At this time, the filter driving assembly 80 rotates to drive the filter 64 to move relative to the cleaning member. When the cleaning member rotates, the filter 64 can be cleaned.

[0214] Among them, the filter driving assembly 80 and the cleaning member can rotate in different directions or in the same direction at different speeds. When the filter driving assembly 80 drives the filter 64 to move, the hair and dust on the filter 64 will fall off the filter 64 to perform preliminary cleaning on the filter 64, and the hair and dust on the filter 64 will fall into the second chamber 112.

[0215] A drain outlet is provided at the bottom of the second chamber 112, and a second filter element is provided at the drain outlet. After the cleaning element completes cleaning of the filter screen 64, the water in the water storage chamber 11 can be discharged from the drain outlet, and pollutants such as hair debris in the water will be collected by the second filter element to prevent pollutants such as hair debris from clogging the drain outlet.

[0216] Among them, when the water level detection component 72 detects that the water level in the water storage chamber 11 has not reached the preset water level, the control device 74 controls the water pump 91 to work, and the water pump 91 pumps the water in the water receiving tray into the water storage chamber 11 to replenish the water storage chamber 11. When the water level detection component 72 detects that the water level in the water storage chamber 11 has reached the preset water level, the water pump 91 stops working.

[0217] At the same time, when the water level in the water storage chamber 11 reaches the preset water level, the floating member 320 moves upward, and the floating member 320 drives the feeding member 310 to feed the sterilization material 63 into the water storage chamber 11 through the first toggle part 312. At the same time, the feeding member 310 closes the switch 520 of the sterilization device 30 through the second toggle part 313. At this time, the control device 74 controls the water pump 91 to turn off and controls the cleaning member and filter screen driving assembly 80 to rotate, so that the cleaning member can clean and sterilize the filter screen 64.

[0218] In some embodiments, when the water level detection component 72 detects that the water level in the water storage chamber 11 has reached a preset water level but the switch 520 of the sterilization device 30 is not closed, the control device 74 controls the air conditioner 7 to issue a second alarm message to remind the user that there is a fault in the sterilization device 30 and the water level detection component 72 at this time, which may be an error in the water level detection component 72 in detecting the water level, or it may be a fault in the switch 520 of the sterilization device 30 or the sterilization device 30.

[0219] In some embodiments, the second alarm information may be used to remind the user through video or picture, or may be used to remind the user through sound, light signal or other means.

[0220] In some embodiments, after the control device 74 controls the water pump 91 to work for the second preset time, the water level detected by the water level detection component 72 has not reached the preset water level. The control device 74 controls the air conditioner 7 to issue a first alarm message to remind the user to repair the air conditioner. At this time, the air conditioner 7 cannot clean the filter 64 normally.

[0221] In some embodiments, the water level detection component 72 can continuously detect the water level in the water storage chamber 11. Once it is detected that the water level in the water storage chamber 11 reaches the preset water level, the control module detects the open and closed state of the switch 520 of the electrolysis unit 510. If the switch 520 of the electrolysis unit 510 is closed, the control module controls the water pump 91 to stop working. If the water level in the water storage chamber 11 is still lower than the preset water level after the water pump 91 continues to work for the second preset time, an alarm is required to remind the user.

[0222] In other embodiments, the water level detection component 72 detects the water level in the water storage chamber 11 every T time. When the water level detection component 72 initially detects that the water level in the water storage chamber 11 is lower than a preset water level, the water pump 91 works for T time. At this time, the water level detection component 72 detects the water level in the water storage chamber 11 again. If the water level detection component 72 detects that the water level in the water storage chamber 11 reaches the preset water level at this time, the control module detects the open and closed state of the switch 520 of the electrolysis unit 510. If the switch 520 of the electrolysis unit 510 is closed, the control module controls the water pump 91 to stop working.

[0223] If the water level detection component 72 detects that the water level in the water storage chamber 11 has not reached the preset water level at this time, the control module controls the water pump 91 to work again for T time. At this time, the water level detection component 72 detects the water level in the water storage chamber 11 again. If the water level in the water storage chamber 11 reaches the preset water level at this time, the control module detects the open and closed state of the switch 520 of the electrolysis unit 510. If the switch 520 of the electrolysis unit 510 is closed, the control module controls the water pump 91 to stop working.

[0224] If the water level in the water storage chamber 11 has not reached the preset water level after the water pump 91 works again for T time, the control module controls the air conditioner 7 to issue a first alarm message to remind the user to repair the air conditioner. At this time, the air conditioner 7 cannot clean the filter 64 normally. Here 2T is the second preset time.

[0225] In some embodiments, the water in the water receiving tray is condensed water generated when the air conditioner 7 is cooling, and the condensed water will collect in the water receiving tray. The second preset time can be 30 minutes, 1 hour, 2 hours or 3 hours, which can be determined according to the local humidity environment. After the air conditioner 7 works for the second preset time, it should be sufficient to generate enough water to make the water storage chamber 11 reach the preset water level.

[0226] If the water pump 91 continues to work for the second preset time and the water in the water storage chamber 11 has not reached the preset water level, it may be that the refrigeration function of the air conditioner 7 fails and cannot store enough condensed water in the water receiving tray. It may also be that the water pump 91 fails. Therefore, the air conditioner 7 needs to issue a first alarm message to remind the user.

[0227] In some embodiments, the first alarm message may be to remind the user through video or picture, or may be to remind the user through sound, light signal or other means.

[0228] Other structures and operations of the air conditioner according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
