[0058] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0059] The embodiments of the present invention are described in detail below, and examples of the embodiments 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.

[0060] In the description of the present invention, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0061] In the description of the present utility model, if the words "first", "second", etc. are described, they are only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0062] In the description of the present utility model, it should be noted that the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model based on the specific content of the technical solution.

[0063] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only part of the embodiments of the present utility model, not all of the embodiments.

[0064] During long-term use of the indoor unit of a wall-mounted air conditioner, dust will accumulate on the filter at the air inlet, which is prone to breed bacteria and affect the air quality, so it needs to be cleaned regularly. In the related art, the indoor unit of a wall-mounted air conditioner uses a brush and flushing to clean the filter. This solution adds a pumping motor and a solenoid valve, which has many parts, high cost, low assembly efficiency, and easy failure. In addition, the flushing process requires repeated operations, the work procedure is complicated, the work efficiency is low, and the cleaning effect is difficult to be satisfactory.

[0065] In addition, the air conditioner indoor unit installs a brush in the space where the filter is located. Since the brush needs to be driven to move, the size of the unit needs to be increased, which may easily lead to a unit size that is too large for users to accept. The solution has poor compatibility and high cost. Moreover, the overall structure of the filter cleaning device is complex, and the filter disassembly and assembly operations are cumbersome, which is not conducive to maintenance.

[0066] In order to solve the above problems, the embodiment of the utility model proposes a filter cleaning module 1000, which is suitable for an air conditioner indoor unit 2000, specifically a wall-mounted air conditioner indoor unit. Figures 1 to 15 The filter cleaning module 1000 according to an embodiment of the present invention is introduced.

[0067] Reference Figure 1 , Figure 3 and Figure 4 As shown, the filter cleaning module 1000 provided by the embodiment of the utility model includes a grille assembly 100, a filter 200, a cleaning box 300 and a driving assembly 400. The grille assembly 100 is provided with an installation space 110, the installation space 110 matches the filter 200, and the filter 200 is movably installed in the installation space 110; the cleaning box 300 is arranged on one side of the grille assembly 100, and a water tank 310 is arranged in the cleaning box 300. The driving assembly 400 is connected to the filter 200, and is used to drive the filter 200 to move between the installation space 110 and the water tank 310, so that the filter 200 can be cleaned by the water in the water tank 310.

[0068] Specifically, the filter cleaning module 1000 of the embodiment is used to be installed on the face frame 700 of the air-conditioning indoor unit 2000, wherein the grille assembly 100 covers the air inlet 710 of the face frame 700, and the grille assembly 100 can be understood as the installation structure of the filter 200, and the installation space 110 is a receiving structure on the grille assembly 100 for the filter 200 to move. The filter 200 can be received in the receiving structure, and the receiving structure has a guiding function, for example, it can be a rail, a guide groove or other guiding structure.

[0069] It can be understood that after the filter 200 is installed in place, when the air conditioner indoor unit 2000 is running, the air will pass through the grille assembly 100 and the filter 200 to enter the interior, and the air can be filtered by the filter 200. When the filter 200 needs to be cleaned, the filter 200 can be guided into the water tank 310 for cleaning under the action of the driving assembly 400, and the filter 200 can be moved out of the water tank 310, so that the filter 200 can move back and forth between the installation space 110 and the water tank 310, and the dust accumulated on the filter 200 can be removed, so that the filter 200 can be automatically cleaned.

[0070] Reference Figure 1As shown, the grille assembly 100 is roughly rectangular, and the installation space 110 is formed inside the grille assembly 100. In the embodiment, the installation space 110 is specifically a cavity structure. The cleaning box 300 and the driving assembly 400 are located at the bottom of the grille assembly 100. The cleaning box 300 is arranged along the length direction of the grille assembly 100. An opening 114 is provided on the side of the installation space 110 facing the cleaning box 300. The opening 114 is also arranged along the length direction of the grille assembly 100. The opening 114 can allow the filter 200 to move in or out of the installation space 110, and the opening 114 is arranged opposite to the notch of the water tank 310. The installation space 110 is connected to the water tank 310 through the opening 114, so that the filter 200 can enter the installation space 110 from the opening 114, and can enter the water tank 310 through the opening 114 for cleaning.

[0071] Among them, the driving component 400 may include a motor 410 and a transmission structure. The motor 410 drives the filter 200 to move through the transmission structure. For example, the transmission structure may be a roller, a gear or other components. Taking the gear as an example, a rack is provided on the filter 200, and the gear is meshed with the rack. The gear is driven to rotate by the motor 410, thereby driving the filter 200 to move.

[0072] Reference Figure 2 As shown, the filter cleaning module 1000 also includes an ultrasonic component 500, which is connected to the cleaning box 300. Specifically, the ultrasonic component 500 is arranged at the bottom of the cleaning box 300. The ultrasonic component 500 is used to generate ultrasonic waves, which are transmitted to the water tank 310 through the ultrasonic waves. This can cause the water in the water tank 310 to produce high-frequency oscillations, which can accelerate the removal of dust and other dirt from the filter 200. In this way, the filter 200 can be cleaned more cleanly, the cleaning efficiency can be improved, and the cleaning is more efficient and convenient.

[0073] It can be understood that the grille assembly 100 is assembled with the filter 200, the ultrasonic assembly 500 and the drive assembly 400 to form the entire module structure, that is, the filter cleaning module 1000 is an independent component, which can be detachably assembled on the face frame 700. When the air conditioner indoor unit 2000 is assembled, after completing the assembly of the filter cleaning module 1000, the entire filter cleaning module 1000 can be installed on the face frame 700, which makes maintenance and installation more convenient and reduces costs. In addition, it can be used on different machine platforms, which is conducive to the expansion of the filter cleaning module 1000 on various machine platforms and has higher compatibility.

[0074] Specific reference Fig.16As shown, the air inlet 710 is located at the top of the face frame 700, and the filter cleaning module 1000 is embedded in the face frame 700. After being installed in place, the cleaning box 300, the driving component 400 and the ultrasonic component 500 are located inside the air conditioner indoor unit 2000, which does not affect the appearance of the whole machine. Of course, the shape of the grille component 100 is not limited to a rectangle, and can also be a square, oval, etc. The specific size of the filter cleaning module 1000 can be designed according to the size of the air inlet 710.

[0075] Reference Figure 3 and Figure 4 As shown, the installation space 110 includes a first cavity 111 and a second cavity 112, and the grille assembly 100 includes a first grille 120, a second grille 130, and a third grille 140, which are arranged in sequence from top to bottom, wherein a first cavity 111 is formed between the first grille 120 and the second grille 130, and a second cavity 112 is formed between the second grille 130 and the third grille 140, and the first cavity 111 is located above the second cavity 112, and the filter screen 200 can move back and forth between the first cavity 111 and the second cavity 112. The first cavity 111 can be understood as an upper track, and the second cavity 112 can be understood as a lower track.

[0076] Specifically, the first cavity 111 is connected to the second cavity 112, and the filter 200 can slide out of the first cavity 111 and enter the second cavity 112, or slide into the first cavity 111 from the second cavity 112. It can be understood that the first cavity 111 and the second cavity 112 are both connected to the water tank 310. Under the action of the driving component 400, the filter 200 slides out of the first cavity 111 and enters the water tank 310, and enters the second cavity 112 after being cleaned by the water tank 310; then slides from the second cavity 112 into the water tank 310, and returns to the first cavity 111 after being cleaned by the water tank 310. Repeating the above operation can clean the filter 200 multiple times, and the ultrasonic component 500 generates an oscillation effect on the water in the water tank 310, so that the cleaning is more efficient.

[0077] Reference Figure 4 As shown, it can be understood that the first cavity 111 and the second cavity 112 are distributed along the height direction, which is conducive to saving the installation space of the grille assembly 100. The water tank 310 is located on the same side of the first cavity 111 and the second cavity 112. The first cavity 111 and the second cavity 112 can guide the two ends of the filter 200 to move, such as Figure 4 The figure shows the state of the filter 200 during the movement process, with one end of the filter 200 located in the first cavity 111 and the other end located in the second cavity 112. That is to say, the two ends of the filter 200 can be separated during the movement and do not affect each other, thereby preventing the filter 200 from bending and overlapping to increase resistance.

[0078] Considering that the filter screen 200 needs to bend to change its direction when moving back and forth between the first cavity 111 and the second cavity 112 , the filter screen 200 in the embodiment may be made of a flexible frame structure to facilitate the filter screen 200 to bend and slide in the first cavity 111 and the second cavity 112 .

[0079] It should be noted that the first grille 120, the second grille 130 and the third grille 140 respectively have a grid structure, all of which allow air to flow through. When the air-conditioning indoor unit 2000 is working normally, the filter 200 can be located in the first cavity 111 or the second cavity 112, so that the air is filtered through the filter 200.

[0080] Reference Figure 1 and Figure 4 As shown, the cleaning box 300 is disposed at one end of the grille assembly 100 along its width direction. Specifically, considering that the cleaning box 300 protrudes from the bottom of the grille assembly 100, Fig.18 It can be understood that in order to enable the filter cleaning module 1000 to be installed on the air-conditioning indoor unit 2000, the cleaning box 300 in the embodiment is located on the front side of the grille assembly 100. When the filter cleaning module 1000 is installed on the air-conditioning indoor unit 2000, the cleaning box 300 is located on the front side of the air-conditioning indoor unit 2000. In this way, the space on the front side of the air-conditioning indoor unit 2000 can be fully utilized, the structural design is reasonable, and the filter 200 can be smoothly moved.

[0081] Reference Figure 1 and Figure 4 As shown, in some embodiments, the driving assembly 400 includes a roller 420 and a driver. The roller 420 is arranged along the length direction of the cleaning box 300. Both ends of the roller 420 are rotatably connected to the opposite side walls in the water tank 310. The roller 420 contacts the filter screen 200. Figure 4 As shown, when the driver drives the drum 420 to rotate, the filter screen 200 can be driven to move around the drum 420 , and the filter screen 200 itself can be bent, so that the filter screen 200 moves along the first cavity 111 and the second cavity 112 .

[0082] It is understandable that the driver in the embodiment is a motor 410, a rotating shaft may be provided in the drum 420, and the motor 410 is connected to the rotating shaft through a gear set 430, so as to drive the drum 420 to rotate. The outer peripheral wall of the drum 420 and the filter screen 200 may be in contact with each other through the connection mode of the transmission gear. For example, the outer peripheral wall of the drum 420 is provided with a transmission gear, and the filter screen 200 is provided with a tooth portion meshing with the transmission gear, so that the drum 420 can drive the filter screen 200 to move when rolling, so that the filter screen 200 is not easy to deviate. By driving the drum 420 to rotate forward or reversely by the motor 410, the filter screen 200 can slide from the first cavity 111 to the second cavity 112, or from the second cavity 112 to the first cavity 111.

[0083] Reference Figure 1 As shown, the motor 410 is installed on the outer wall on the right side of the cleaning box 300, and the gear set 430 includes a driving wheel and a transmission wheel. The driving wheel is connected to the driving shaft of the motor 410, and the transmission wheel is connected to the rotating shaft. The driving wheel and the transmission wheel are meshed to realize the driving roller 420 to rotate.

[0084] Reference Figure 4 As shown, since the drum 420 is located in the water tank 310, when the drum 420 drives the filter 200 to move around it, different parts of the filter 200 can be immersed in the water tank 310 for cleaning, and the dust on the surface is removed by washing with water, and the ultrasonic component 500 vibrates the water in the water tank 310, making the cleaning cleaner and more efficient. Compared with the cleaning method of brush and water flushing, it can prevent dust from flying, the cleaning procedure is simpler, the cleaning cleanliness is higher, and the cost is lower.

[0085] It should be noted that the embodiment of the utility model adopts a double cavity and a roller 420. The double cavity not only has a guiding effect on the filter 200, but also can be used as an installation space 110 for the filter 200. Only one motor 410 and one roller 420 are required to meet the driving requirements, realize the back and forth rolling cleaning of the filter 200, simplify the structure, achieve a reduction in material costs and an improvement in production efficiency, and at the same time reduce costs It can also improve the reliability of the filter cleaning module 1000.

[0086] Considering that the grille assembly 100 has a structure of three layers of grilles and two layers of cavities, and the overall thickness is relatively high, the filter cleaning module 1000 will increase the height of the entire machine when installed on the top of the air conditioner indoor unit 2000. The inventors of the utility model have found that the air conditioner indoor unit 2000 adopts the above structure, and its body height will increase by 40mm, resulting in a body size that is too large and difficult for users to accept. Therefore, in some embodiments of the utility model, the structure of the grille assembly 100 is further optimized to reduce the overall thickness.

[0087] Reference Figure 4As shown, in some embodiments, in the direction of the grille assembly 100 away from the water tank 310, that is, along the front-to-back direction of the grille assembly 100, the lengths of the first grille 120 and the third grille 140 are both greater than the length of the second grille 130, and the first cavity 111 and the second cavity 112 are connected at one end away from the water tank 310 to form a third cavity 113, and the third cavity 113 is located between the first grille 120 and the third grille 140; it can be understood that the lengths of the first cavity 111 and the second cavity 112 are equal or close, the length of the third cavity 113 can be close to or slightly smaller than the length of the first cavity 111 or the second cavity 112, the third cavity 113 is a single-layer cavity, and the filter 200 can slide from the first cavity 111 into the third cavity 113, and can slide from the second cavity 112 into the third cavity 113.

[0088] It can be understood that a portion of the installation space 110 has a double-layer cavity and the other portion has a single-layer cavity, wherein the double-layer cavity is located at the front of the grille assembly 100 and the single-layer cavity is located at the rear of the grille assembly 100, the height of the third cavity 113 is smaller than the distance between the top wall of the first cavity 111 and the bottom wall of the second cavity 112, and the single-layer cavity has a smaller thickness dimension relative to the double-layer cavity, which can reduce the thickness of the rear of the grille assembly 100.

[0089] Specifically, the third cavity 113 can be understood to be formed by merging the rear of the first cavity 111 and the second cavity 112. The sum of the lengths of the third cavity 113 and the first cavity 111 or the second cavity 112 is set equal to or greater than the length of the filter 200. The length of the third cavity 113 is determined according to the length of the second grid 130, considering that the second grid 130 is used to separate the first cavity 111 and the second cavity 112 to avoid overlapping of the two ends of the filter 200. In some preferred embodiments, the sum of the length of the second grid 130 and the diameter of the drum 420 is set equal to or greater than half of the filter 200.

[0090] In addition, the heights of the first cavity 111, the second cavity 112, and the third cavity 113 are slightly greater than the thickness of the filter 200, so that there is enough clearance for the movement of the filter 200, and the specific sizes of the first cavity 111, the second cavity 112, and the third cavity 113 can be set according to the actual size of the filter 200. In order to maintain a uniform thickness distribution at the rear of the grille assembly 100, the third grille 140 is thickened at the rear position, which is beneficial to improving the structural strength of the rear of the grille assembly 100 while ensuring that the third cavity 113 has enough clearance.

[0091] Continue to refer to Figure 4As shown, it should be noted that since the cleaning box 300 is located at the lower front part of the grille assembly 100, the space on the front side of the air-conditioning indoor unit 2000 can be used. In order to match the position of the cleaning box 300, the front part of the grille assembly 100 has a bending section 150. Specifically, the first grille 120, the second grille 130 and the third grille 140 are all bent to form the bending section 150, so that the first grille 120, the second grille 130 and the third grille 140 extend to the position of the water tank 310 respectively, so that the first cavity 111 and the second cavity 112 can be connected to the water tank 310, and the front part of the grille assembly 100 does not affect the size of the whole machine.

[0092] That is to say, when the front portion of the grille assembly 100 is bent downward and the rear portion has only a single-layer cavity, the thickness of the grille assembly 100 can be reduced, thereby facilitating the reduction of the height of the fuselage. Figure 4 According to the structure of the embodiment shown, the height of the air conditioner indoor unit 2000 does not need to be increased by 40 mm, and the height of the air conditioner indoor unit 2000 can even be reduced.

[0093] Understandably, refer to Figure 1 As shown, since the cleaning box 300 and the driving assembly 400 are both located on the front side of the air-conditioning indoor unit 2000, compared with the method of installing them on the left or right side of the air-conditioning indoor unit 2000, the space on the front side of the air-conditioning indoor unit 2000 is fully utilized, and the occupied space on the left and right sides is reduced, which can further reduce the length of the fuselage, and the user acceptance is higher.

[0094] Reference Figure 1 and Figure 4 As shown, in the embodiment, the cleaning box 300 is made of plastic material, and the grille assembly 100 and the cleaning box 300 are made into an integrated injection molding structure through an injection molding process. After injection molding, the cleaning box 300 is fixedly connected to the lower side of the front end of the grille assembly 100, which reduces the number of parts, makes installation more convenient, and has a stable and reliable structure.

[0095] Reference Figure 3 and Figure 4 As shown, in some embodiments, a metal part 320 is provided on the outside of the cleaning box 300. The metal part 320 is specifically a sheet metal part, which is wrapped around the outer surface of the cleaning box 300, so that the inner layer of the cleaning box 300 is a plastic layer and the outer layer is a metal layer; the ultrasonic component 500 includes a plurality of ultrasonic oscillator plates 510, and the plurality of ultrasonic oscillator plates 510 are arranged at intervals along the length direction of the cleaning box 300 and are connected to the metal part 320. Ultrasonic waves are transmitted through the metal part 320, so that the water in the water tank 310 can have a sufficiently large oscillation frequency, thereby effectively cleaning the filter 200.

[0096] Combination Figure 2 and Figure 3 As shown, in the embodiment, there are four ultrasonic oscillating pieces 510, and the four ultrasonic oscillating pieces 510 are connected to the bottom of the cleaning box 300. Of course, the number of ultrasonic oscillating pieces 510 is not limited to four, and can also be three, five or more, depending on the actual application requirements.

[0097] The ultrasonic oscillator 510 can be distributed in parallel or in series on the bottom side of the cleaning box 300. The ultrasonic oscillator 510 is a piezoelectric element that converts electrical energy into mechanical energy. It is composed of piezoelectric ceramic materials and metal electrodes. When an electric field is applied, the piezoelectric material will produce a piezoelectric effect, thereby generating mechanical vibrations to form ultrasonic waves. Ultrasonic waves have the characteristics of short wavelength and high frequency. They can generate high-frequency oscillations through the metal parts 320 of the cleaning box 300, thereby causing the water in the water tank 310 to oscillate. The high-frequency oscillations of water molecules will wash away the dust on the filter 200, thereby achieving rapid cleaning of the filter 200, which is cleaner than cleaning with a brush.

[0098] In some embodiments, the cleaning box 300 further includes an insulating shell 360, which is made of plastic material, also called a plastic shell, and covers the outer surface of the metal part 320, that is, the cleaning box 300 includes a plastic box body, a metal layer and a plastic shell from the inside to the outside, and the plastic shell has an insulating protection function to prevent the metal part 320 from being exposed and prevent the generated ultrasonic wave from hurting people. Of course, the insulating shell 360 is not limited to plastic material, and can also be made of materials such as silicone and ceramic.

[0099] It should be noted that the metal part 320 can be connected to the cleaning box 300 by bonding, interference fit, etc.; the plastic shell can be connected to the metal part 320 by bonding, interference fit, etc., and the specific selection is made according to actual application requirements.

[0100] Reference Figure 4 As shown, in some embodiments, the side wall of the water tank 310 is provided with an overflow port 330, and the height h1 of the overflow port 330 relative to the bottom wall of the water tank 310 is set to be greater than the height h2 of the drum 420 relative to the bottom wall of the water tank 310. Specifically, the overflow port 330 is provided with one, and the overflow port 330 can be set at a slot position close to the water tank 310. The overflow port 330 can be connected to the water receiving tank in the air-conditioning indoor unit 2000, and the water receiving tank is used to receive condensed water.

[0101] It can be understood that the drum 420 drives the filter 200 to roll, so that the filter 200 enters the water of the water tank 310 for cleaning. Considering that when the water level of the water tank 310 is too high, water is easy to overflow the water tank 310 and flow into the air-conditioning indoor unit 2000, affecting the normal operation of the air-conditioning indoor unit 2000, the overflowing water can be drained into the water receiving tank through the overflow port 330, and the water can be drained through the water receiving tank to prevent excessive water from overflowing and affecting the operation of components such as the motor 410.

[0102] Of course, this is only an example, and the number of overflow ports 330 is not limited to one, but can also be two or more, and the overflow ports 330 can be evenly distributed along the length direction of the cleaning box 300; in addition, the overflow ports 330 are not limited to being connected to the water receiving tank, but can also be directly discharged from the air conditioner indoor unit 2000 through a drain pipe.

[0103] Reference Figure 1 and Figure 3 As shown, the cleaning box 300 is provided with a fixing member 340, one end of the fixing member 340 is connected to a side wall of the cleaning box 300, and the other end is arranged toward the other opposite side wall and connected to the grille assembly 100, so that the fixing member 340 is fixed at the notch of the water tank 310. The fixing member 340 has a limiting effect on the drum 420, which can effectively prevent the drum 420 from separating from the water tank 310 during rotation.

[0104] Specifically, the water tank 310 is roughly in the shape of a rectangular parallelepiped, and the notch of the water tank 310 is located on the upper side. The size of the notch is larger than the size of the drum 420, so that the drum 420 can be installed in the water tank 310 through the notch. The fixing member 340 is an independent part, which can be a buckle, a baffle and other components. Taking the buckle as an example, a boss 350 is provided on the outer wall of the water tank 310 away from the grille assembly 100, and a slot is provided on the grille assembly 100. The slot can be set at the position of the first grille 120 or the second grille 130. One end of the buckle is fixedly connected to the boss 350, and the other end is inserted into the slot, so that the buckle can be fixed at the notch, wherein the buckle can be connected to the boss 350 by screws, which is convenient for installation.

[0105] Of course, this is only an example, and the buckle is not limited to being connected to the cleaning box 300 by screws, and can also be fixed by buckling, etc. The fixing member 340 is not limited to one, and can also be two or more, which is selected according to the size of the water tank 310 and the drum 420.

[0106] It can be understood that since the installation space 110 is formed inside the grille assembly 100 and the opening 114 of the installation space 110 is close to the cleaning box 300, the filter 200 can only be moved out of the installation space 110 from the opening 114. Considering the limitations of the above-mentioned assembly structure, in order to facilitate the disassembly of the filter 200, the grille assembly 100 of the embodiment of the utility model adopts a detachable assembly structure.

[0107] Reference Figure 5 As shown, in some embodiments, the grille assembly 100 includes a bracket 160, the first grille 120 is detachably connected to the bracket 160, the second grille 130 and the third grille 140 are an integrally formed structure with the bracket 160, and the bracket 160 can be understood as a frame structure of the grille assembly 100, which is roughly rectangular in shape. The first grille 120 is located at the top of the bracket 160. After disassembling the first grille 120, the filter 200 can be moved to the first cavity 111 and taken out. The operation is simple, and the filter 200 is easy to replace and assemble. The installation and maintenance of the filter cleaning module 1000 are simpler and faster.

[0108] It should be noted that the first grille 120 and the bracket 160 can be connected by buckling, plugging, screw connection, etc. For example, the first grille 120 is provided with a buckle, and the bracket 160 is provided with a slot, and the buckle and the slot are fixed together. The specific settings can be made according to application requirements.

[0109] Reference Figure 7 and Figure 8 As shown, in the embodiment, the first cavity 111 and the second cavity 112 are distributed along the height direction, and the water tank 310 is located on the same side of the first cavity 111 and the second cavity 112. The first cavity 111 and the second cavity 112 can guide the movement of the two ends of the filter 200. During the movement, the two ends of the filter 200 can be separated and do not affect each other, thereby preventing the filter 200 from bending and overlapping itself to increase resistance.

[0110] Reference Figure 1 and Figure 5 As shown, the filter cleaning module 1000 of the present utility model embodiment includes two filters 200. Figure 1 The direction shown is a reference direction, and the two filters 200 are respectively a left filter and a right filter. Two installation spaces 110 are formed in the grille assembly 100, including a left installation space 110 and a right installation space 110. The left filter is movably installed in the left installation space 110, and the right filter is movably installed in the right installation space 110, so as to realize the movable assembly of the left filter and the right filter.

[0111] It can be understood that the left installation space 110 and the right installation space 110 are respectively provided with an opening 114, and the two openings 114 are both arranged toward the sink 310, so that the left filter can enter the sink 310 from the left installation space 110 for cleaning, and the right filter can enter the sink 310 from the right installation space 110 for cleaning, and the left and right filters 200 can be cleaned at the same time.

[0112] It should be noted that Figure 1In the embodiment shown, the two filters 200 can be driven to move simultaneously by the roller 420, and the motor 410 is installed on the right side of the cleaning box 300. The motor 410 can drive the roller 420 to rotate through the gear set; in some embodiments, two rollers 420 can be provided, one of which is connected to the left filter and the other is connected to the right filter. The two rollers 420 are linked by a rotating shaft or other transmission components, so that one motor 410 can drive two rollers 420 to rotate. In addition, Figure 1 The cleaning box 300 in the embodiment is a single box structure, that is, the two filters 200 share the same cleaning box 300 .

[0113] Of course, this is only an example, and the number of the filter screen 200 and the installation space 110 is not limited to two, and can also be three or more, depending on the actual application requirements.

[0114] Reference Figure 5 As shown, in some embodiments, two first grilles 120 are provided, and a first mounting position 164 and a second mounting position 165 are provided on the top of the bracket 160, and the first mounting position 164 and the second mounting position 165 are arranged at intervals along the length direction of the bracket 160. One of the first grilles 120 is slidably connected to the first mounting position 164, and the other first grille 120 is slidably connected to the second mounting position 165, so that both first grilles 120 can be detachably connected to the bracket 160. The two first grilles 120 can also be understood as a left grille and a right grille, so that the left filter and the right filter can be disassembled and assembled separately, and maintenance is more flexible.

[0115] It can be understood that the left installation space 110 and the right installation space 110 include a first cavity 111 and a second cavity 112 respectively, and the two installation spaces 110 have a second grille 130 and a third grille 140 respectively. Figure 8 As shown, taking the left installation space 110 as an example, the left installation space 110 includes a first cavity 111 and a second cavity 112, and the first grille 120, the second grille 130 and the third grille 140 are arranged in sequence from top to bottom, and the first cavity 111 is formed between the first grille 120 and the second grille 130, and the second cavity 112 is formed between the second grille 130 and the third grille 140, wherein the first grille 120 is a detachable structure to facilitate the removal of the left filter.

[0116] Under the driving action of the driving component 400, the left filter moves out of the first cavity 111 along the opening 114 and enters the water tank 310 for cleaning, and then enters the second cavity 112 after passing through the water tank 310. It can also be moved from the second cavity 112 into the water tank 310, and then enters the first cavity 111 after being cleaned by the water tank 310. In this way, the left filter is driven to move back and forth for multiple cleanings, and ultrasonic waves are generated by the ultrasonic component 500 to cause the water in the water tank 310 to produce high-frequency oscillations to improve the cleaning efficiency and make the left filter clean more thoroughly.

[0117] Reference Figure 1 , Fig.10 and Fig.11 As shown, it should be noted that both the left filter and the right filter are driven by a driving assembly 400. In the embodiment, the driving assembly 400 includes a first roller 421, a second roller 422 and a motor 410, and the cleaning box 300 includes a first box body 301 and a second box body 302, wherein the first box body 301 corresponds to the left installation space 110, and the first roller 421 is extended along the length direction of the first box body 301. Both ends of the first roller 421 are rotatably connected in the first box body 301, and the first roller 421 is connected to the left filter. The motor 410 drives the first roller 421 to rotate, which can drive the left filter to move around the first roller 421, thereby causing the left filter to move along the first cavity 111 and the second cavity 112 in the left installation space 110. The second box body 302 corresponds to the right installation space 110, the second roller 422 is extended along the length direction of the second box body 302, the two ends of the second roller 422 are rotatably connected in the second box body 302, the second roller 422 is connected to the right filter screen, and the motor 410 drives the second roller 422 to rotate, which can drive the right filter screen to move around the second roller 422, so that the right filter screen moves along the first cavity 111 and the second cavity 112 in the right installation space 110. It should be noted that the first roller 421 and the second roller 422 are driven by the same motor 410, and can realize synchronous operation, thereby driving the left filter screen and the right filter screen to be cleaned synchronously.

[0118] Reference Figure 8 As shown, taking the first roller 421 and the left filter as an example, the outer peripheral wall of the first roller 421 and the left filter can be in contact with each other through the connection of a transmission gear. For example, the outer peripheral wall of the first roller 421 is provided with gear teeth, and the left filter is provided with a tooth portion meshing with the gear teeth. In this way, the first roller 421 can drive the left filter to move when rolling, so that the left filter is not easily offset and the operation is more stable.

[0119] Combination Figure 7 , Fig.10 and Fig.11It can be understood that the motor 410 is fixedly connected to the middle position of the bracket 160, the driving assembly 400 also includes a gear set and a transmission shaft 440, and a support 161 is formed in the middle position of the bracket 160, the support 161 is located between the first mounting position 164 and the second mounting position 165, and the first box body 301 and the second box body 302 are separated by the support 161, the support 161 is provided with an installation cavity, and the installation cavity is located between the first box body 301 and the second box body 302, and the gear set is rotatably connected in the installation cavity, so that the driving assembly 400 can be isolated from the water, and the size of the water tank 310 is not affected by the gear set.

[0120] Reference Fig.10 and Fig.11 As shown, the gear set in the embodiment has three gears, the motor 410 is located outside the installation cavity, the motor 410 is connected to one of the gears through a driving shaft, the transmission shaft 440 is connected to the gear far away from the motor 410, and the two ends of the transmission shaft 440 pass through the first box body 301 and the second box body 302 respectively, and are connected to the first roller 421 and the second roller 422, so that the motor 410 drives the gear set to operate, and drives the transmission shaft 440 to rotate through the gear set, so that the transmission shaft 440 can drive the first roller 421 and the second roller 422 to rotate synchronously, and the transmission shaft 440 and the first roller 421 and the second roller 422 can be connected by direct coupling, couplings, etc., so that one motor 410 can drive two rollers 420 to rotate at the same time.

[0121] It is understandable that, since the driving assembly 400 is installed in the middle of the bracket 160 and drives the two rollers 420 to rotate at the same time, the force on the two rollers 420 can be more uniform, the rotation consistency can be better, and the movement of the left filter and the right filter can be more stable. Figure 1 The overall structure of the illustrated embodiment can also save length space. The drive assembly 400 will not increase the overall length of the filter cleaning module 1000, which facilitates module installation and can shorten the length of the power cord of the motor 410. In the embodiment, the length of the power cord can be reduced from 1 meter to 0.5 meters, reducing wiring costs.

[0122] It should be noted that the size of the first box body 301 and the second box body 302 in the embodiment can accommodate the first roller 421 and the second roller 422, and respectively drive the left filter and the right filter into the water tank 310 for cleaning. It can be understood that the greater the depth of the water tank 310, the greater the area of ​​the filter 200 entering the water tank 310, the more the water level soaks the filter 200, and the better the cleaning effect, so that the filter 200 can be cleaned to the greatest extent. In addition, the ultrasonic component 500 is combined to vibrate the water in the water tank 310, making the cleaning cleaner and more efficient; compared with the cleaning method of brush and water flushing, it can prevent dust from flying, and the cleaning cleanliness is higher and the cost is lower.

[0123] In the embodiment of the utility model, the first cavity 111 and the second cavity 112 not only have a guiding function for the filter 200, but also can be used as the installation space 110 of the filter 200. Only one motor 410 and two rollers 420 are needed to meet the driving requirements, realize the back-and-forth rolling cleaning of the left filter and the right filter, simplify the structure, achieve the reduction of material costs and the improvement of production efficiency, and at the same time improve the reliability of the filter cleaning module 1000 while reducing costs.

[0124] Reference Fig.11 As shown, it can be understood that the driving assembly 400 also includes a bearing, through which the transmission shaft 440 is supported, so that the transmission shaft 440 runs more stably. Considering that the transmission shaft 440 needs to pass through the cleaning box 300 and connect with the two rollers 420, in some embodiments, a waterproof ring 450 is provided at the bearing, and the waterproof ring 450 can prevent the water in the water tank 310 from flowing out from the gap between the transmission shaft 440 and the cleaning box 300, thereby increasing the waterproof sealing performance.

[0125] Specifically, since the two ends of the transmission shaft 440 pass through the first box body 301 and the second box body 302 respectively, two bearings are provided, the two bearings respectively support the two ends of the transmission shaft 440, and waterproof rings 450 are respectively provided at the bearings at the two ends, so that the waterproofness of the first box body 301 and the second box body 302 can be improved. Among them, the waterproof ring 450 can be a silicone sealing ring or a sealing ring in other forms, and the number of waterproof rings 450 is not limited to one, and more than two waterproof rings 450 can also be provided at the same bearing to improve the sealing performance.

[0126] It is understandable that, since the two first grilles 120 are respectively slidably connected to the first mounting position 164 and the second mounting position 165, the embodiment of the utility model limits the two first grilles 120 by adding a limiting structure to ensure that they are not easily separated from the bracket 160 after being installed in place. The limiting structure is described below with a specific example.

[0127] Reference Fig.12 and Fig.13 As shown, the first grille 120 on the left is the left grille member 121, and the first grille 120 on the right is the right grille member 122. The grille assembly 100 also includes a first limiting member 170 and a second limiting member 180. The left grille member 121 is provided with a first limiting rib 1211, which is located on the side of the left grille member 121 close to the cleaning box 300 and extends along the length direction of the left grille member 121; the first limiting member 170 is specifically in the shape of a long strip, and a first card slot 171 is provided on the first limiting member 170, and the first card slot 171 extends along the length direction of the first limiting member 170.

[0128] It is understandable that guide grooves 166 are formed on both sides of the first installation position 164, so that the left grille member 121 can slide into the first installation position 164 along the guide grooves 166. During assembly, when the left grille member 121 is introduced into the first installation position 164 by a horizontal push, the two ends of the first limiting member 170 are respectively inserted into the guide grooves 166 on both sides, and the first limiting rib 1211 is inserted into the first clamping groove 171 for limiting cooperation, so as to prevent the left grille member 121 from loosening.

[0129] Combination Figure 8 It can be understood that the first limiting rib 1211 is located at the end of the left grille member 121, and the first slot 171 is set toward the left grille member 121. The first limiting rib 1211 cooperates with the first slot 171 to prevent the left grille member 121 from shaking up and down, and the structure is more stable and reliable.

[0130] It should be noted that in the embodiment, a groove is provided on the side of the support 161 facing the first mounting position 164, one end of the first stopper 170 can be inserted into the groove for fixing, and the other end can be fixedly connected to the support 160 by a screw, so that the left grille 121 can be fixed by a single screw, which is convenient for assembly. In some embodiments, the left grille 121 is fixed to the support 160 by a snap-fit ​​method, but the snap-fit ​​fixing method has the problems of being difficult to disassemble and taking a long time to disassemble. Compared with the snap-fit ​​fixing method, the use of Fig.12 The first stopper 170 of the illustrated embodiment fixes the left grille member 121 , making disassembly more convenient, and facilitating installation and maintenance, thereby helping to reduce costs.

[0131] Reference Fig.13 As shown, the right grille member 122 is provided with a second limiting rib 1221, which is arranged on the side of the right grille member 122 away from the left grille member 121 and extends along the width direction of the right grille member 122; the second limiting member 180 is specifically in the shape of a long strip, and a second card slot (not shown in the drawings) is provided on the second limiting member 180, and the second card slot extends along the length direction of the second limiting member 180.

[0132] It can be understood that in the embodiment, guide grooves 166 are formed on both sides of the second mounting position 165, and the right grille member 122 moves into the second mounting position 165 through the guide grooves 166. A groove matching the second limiting member 180 is formed on the side of the second mounting position 165 away from the first mounting position 164, so that the second limiting member 180 can be assembled with the second limiting member 180 into the second mounting position 165, and the second limiting rib 1221 cooperates with the second card slot for limiting, which can prevent the right grille member 122 and the second limiting member 180 from loosening, prevent the second grid from shaking up and down, and the structure is stable and reliable.

[0133] It should be noted that, in the embodiment, the first and second stoppers 180 can be fixedly connected to the bracket 160 by a screw, which is convenient for assembly. When disassembling, the right grille member 122 and the second stopper 180 can be moved out of the second installation position 165 along the guide groove 166. Compared with the fixing method of the buckle, the structure is simplified, the disassembly is more convenient, and it is easy to install and maintain, which is conducive to reducing costs.

[0134] In addition, in the embodiment, the two first grilles 120 are both installed on the bracket 160 by a flat push method, which does not require precise positioning and installation, and the installation operation is simple, and the first stopper 170 and the second stopper 180 are installed in different ways, which has a foolproof effect and is easy to install. Of course, this is only an example, and the installation positions of the first stopper 170 and the second stopper 180 are not limited to the structure shown in the above embodiment. For example, the first stopper 170 is set on the left side of the left grille member 121, and the second stopper 180 is set on the front side of the right grille member 122.

[0135] Reference Fig.12 and Fig.13 As shown, the left grille member 121 and the right grille member 122 are respectively provided with an extension section 123 , and the extension section 123 is arranged toward the cleaning box 300 . The left grille member 121 and the right grille member 122 are respectively detachably connected to the cleaning box 300 via the extension section 123 .

[0136] In some embodiments, the extension section 123 is connected to the cleaning box 300 by screws, which is convenient for installation and removal, and the connection between the extension section 123 and the cleaning box 300 further improves the reliability of the left grille member 121 and the right grille member 122. After being installed in place, the extension section 123 covers the notch position of the water tank 310, which can prevent the first roller 421 and the second roller 422 from being separated from the cleaning box 300.

[0137] Reference Fig.12 As shown, a first limiting groove 1212 is provided on the side of the left grille member 121 away from the cleaning box 300, and the first limiting groove 1212 is formed on the frame structure of the left grille member 121; a first limiting buckle 1641 is provided on the bracket 160, and the first limiting buckle 1641 is formed on the peripheral wall position of the first installation position 164, and can be a convex block or convex rib, etc., protruding from the top of the peripheral wall, and located at the corner position of the first installation position 164; the first limiting groove 1212 is a concave structure formed on the upper surface of the left grille member 121, and the first limiting buckle 1641 matches the first limiting groove 1212. When the left grille member 121 is pushed horizontally into the first installation position 164, the first limiting buckle 1641 is inserted into the first limiting groove 1212, so that the left grille member 121 can be pressed by the first limiting buckle 1641, so that the left grille member 121 can be limited.

[0138] It should be noted that in the embodiment, the first mounting position 164 is roughly rectangular, and the first limiting buckle 1641 can be set at two corners of the first mounting position 164 away from the cleaning box 300, so that the two corners of the left grille member 121 can be simultaneously limited. Since the first limiting member 170 and the first limiting rib 1211 limit the front side of the left grille member 121, the first limiting buckle 1641 and the first limiting groove 1212 cooperate to limit the rear side of the left grille member 121, so that the front and rear sides of the left grille member 121 are both limited, and the disassembly and assembly are simple, which effectively prevents the left grille member 121 from moving up and down and detaching from the bracket 160, and the structure is more stable and reliable.

[0139] Reference Fig.13 As shown, a second limiting groove 1222 is provided on the side of the right grille member 122 away from the cleaning box 300, and the second limiting groove 1222 is formed on the frame structure of the right grille member 122; a second limiting buckle 1651 is provided on the bracket 160, and the second limiting buckle 1651 is formed on the peripheral wall position of the second installation position 165, and the second limiting buckle 1651 matches the second limiting groove 1222. When the right grille member 122 is pushed horizontally into the second installation position 165, the second limiting buckle 1651 is inserted into the second limiting groove 1222, so that the right grille member 122 can be limited. The assembly structure of the second limiting buckle 1651 and the second limiting groove 1222 can be specifically referred to Fig.12 The structure of the first limiting buckle 1641 and the first limiting groove 1212 is shown in FIG.

[0140] It should be noted that the second limiting member 180 and the second limiting rib 1221 limit the right side of the right grille member 122, and the second limiting buckle 1651 and the second limiting groove 1222 cooperate to limit the rear side of the right grille member 122, so that the different sides of the right grille member 122 are limited, which effectively prevents the right grille member 122 from moving up and down and detaching from the bracket 160, and the assembly is more stable and reliable.

[0141] Since the cleaning box 300 is located at the front side of the air-conditioning indoor unit 2000 and the driving assembly 400 is installed in the middle position of the grille assembly 100, the cleaning box 300 and the driving assembly 400 do not occupy the space on the left and right sides of the air-conditioning indoor unit 2000, the length of the fuselage can be reduced, and the user acceptance is higher.

[0142] Reference Figure 6As shown, in some embodiments, the first box body 301 and the second box body 302 are both metal parts, specifically made of sheet metal. The ultrasonic component 500 includes two ultrasonic oscillating plates 510, and the two ultrasonic oscillating plates 510 are respectively connected to the bottom of the first box body 301 and the second box body 302. The ultrasonic wave is transmitted by the sheet metal, so that the water in the water tank 310 can have a sufficiently large oscillation frequency, so that the filter 200 can be effectively cleaned.

[0143] and Figure 2 The difference between the shown embodiments is that Figure 6 In the illustrated embodiment, the ultrasonic oscillator 510 is rectangular, and two ultrasonic oscillator plates 510 are respectively extended in the length direction of the first box body 301 and the second box body 302. It can be understood that each box body uses a single ultrasonic oscillator plate 510 to generate ultrasonic waves. Compared with the structure of two or more ultrasonic oscillator plates 510, a single ultrasonic oscillator plate has a longer length, so that a single ultrasonic oscillator plate 510 can be used to replace two or more ultrasonic oscillator plates 510 of smaller size, thereby reducing costs and improving cleaning rates. In terms of cost saving, the main cost is to reduce assembly costs, material costs and electrical control costs, because the cost of a single ultrasonic oscillator plate 510 is equivalent to half the cost of two plates, the installation efficiency is higher, and the power supply cost is also reduced by 1 / 3.

[0144] It should be noted that since two or more ultrasonic oscillator plates 510 are connected in parallel or in series, the cost of electronic control will be doubled. The embodiment of the utility model is designed to use a high-power single-chip ultrasonic oscillator plate 510. Taking the first box body 301 as an example, the ultrasonic oscillator plate 510 is set in the middle position of the first box body 301. This can achieve an effective cleaning effect while reducing the cost of electronic control.

[0145] Reference Figure 5 and Figure 7 As shown, in some embodiments, the cleaning box 300 also includes an insulating shell 360, which is made of plastic, silicone or other insulating materials. Taking the plastic insulating shell 360 as an example, the insulating shell 360 can be an integral structure, and the insulating shell 360 covers the outside of the first box body 301 and the second box body 302. The plastic shell has an insulating protection function, avoids exposure of sheet metal parts, and can prevent the generated ultrasonic waves from hurting people.

[0146] Reference Fig.14 and Fig.15As shown, in some embodiments, the insulating shell 360 includes a first shell 361 and a second shell 362, that is, the insulating shell 360 adopts a split structure. Among them, the first shell 361 is used to cover the first box body 301, and the second shell 362 is used to cover the second box body 302. In the embodiment, the length of the first box body 301 and the second box body 302 are the same as the length of the first shell 361 and the second shell 362. The bracket 160 is provided with a buckle 163 and a slide 162. The first shell 361 and the second shell are respectively provided with a slot on the opposite side. The buckle 163 is located in the middle position of the bracket 160. The slide 162 extends along the left and right directions of the cleaning box 300. The first shell 361 and the second shell 362 can slide along the slide 162. Through the guiding effect of the slide 162, the first shell 361 and the second shell 362 can be relatively spliced ​​to form the insulating shell 360. The buckle 163 is engaged with the slot for buckling, so that the first shell 361 and the second shell 362 can be fixed, and the assembly is simple. Fig.14 and Fig.15 3 shows the installation state where the first shell part 361 is assembled in place and the second shell part 362 moves along the slide groove 162 .

[0147] Specifically, the first shell portion 361 and the second shell portion 362 are respectively provided with open ports, and the port of the first shell portion 361 is arranged opposite to the port of the second shell portion 362. When the first shell portion 361 and the second shell portion 362 are assembled into place along the slide groove 162, the two ports can abut against each other, so that the first shell portion 361 and the second shell portion 362 are spliced ​​to form an insulating shell 360, and are fixed by the buckle 163 cooperating with the slot.

[0148] Combination Fig.11 It can be understood that the buckle 163 is arranged at the bottom of the support 161 and protrudes from the bottom surface of the first box body 301 and the second box body 302. The buckle 163 extends toward both sides to form a first plug-in end 1631 and a second plug-in end 1632. The end of the first shell 361 facing the second shell 362 is provided with a first slot 3611, and the end of the second shell 362 facing the first shell 361 is provided with a second slot 3621. The first plug-in end 1631 is engaged with the first slot 3611 and the second plug-in end 1632 is engaged with the second slot 3621 to achieve the fixation of the first shell 361 and the second shell 362. Taking the first shell 361 and the first slot 3611 as an example, the first shell 361 moves along the slide groove 162 toward the first shell 361. When it approaches the position of the second shell 362, the first plug-in end 1631 can be inserted into the first slot 3611 for buckling, thereby achieving the purpose of fixing the first shell 361.

[0149] It is understandable that the first shell 361 and the second shell 362 can be spliced ​​together by the buckle 163 and the slot, and it is also easy to disassemble, so that the first shell 361 and the second shell 362 can be quickly separated from the cleaning box 300. The buckle 163 and the slot have different connection forms, and its design can fix the opposite end of the first shell 361 and the second shell 362 to prevent them from moving up and down and shaking left and right. In the production process, the above-mentioned installation method effectively improves the installation efficiency and saves the cost of structural parts. The specific form of the buckle 163 and the slot can be selected according to the application requirements.

[0150] It should be noted that, combined with Figure 8 and Fig. 9 As shown, the first shell 361 can be smoothly installed along the slide groove 162, which can effectively prevent mis-installation, so that the first shell 361 can be accurately assembled in place. In addition, in some embodiments, the first shell 361 and the second shell 362 can be connected to the bracket 160 by screws, and specifically, the screw connection position can be set away from the end of the buckle 163, so that the first shell 361 and the second shell 362 can be fixed by one screw, thereby improving installation efficiency.

[0151] In addition, since the insulating shell 360 is wrapped around the outside of the first box body 301 and the second box body 302, when water overflow or leakage occurs in the first box body 301 and the second box body 302, the insulating shell 360 can prevent water from further flowing to the outside of the cleaning box 300, thereby avoiding water leakage in the cleaning box 300 and improving product reliability.

[0152] It should be noted that, considering that the first box body 301 and the second box body 302 are both sheet metal parts, in order to facilitate the assembly of the first roller 421 and the second roller 422, in some embodiments, a support seat 311 is respectively provided in the first box body 301 and the second box body 302, and the two ends of the first roller 421 and the second roller 422 are rotatably connected to the support seat 311 respectively, and the support seat 311 is made of plastic. The support seat 311 is roughly U-shaped, and its bottom is connected to the inner cavity of the two box bodies, so that the two rollers 420 can be immersed in water, ensuring that the filter 200 is in contact with water.

[0153] Reference Figure 8 and Fig. 9As shown, taking the first box body 301 as an example, the support seat 311 is fixed on the inner side of the first box body 301, a slide groove 162 is formed on one side of the bracket 160, and flanges are respectively provided on both sides of the first shell 361, the first box body 301 and the support seat 311, wherein the flange on one side can be inserted into the slide groove 162 for assembly, and the first flange 3111 of the support seat 311, the second flange 3011 of the first box body 301 and the third flange 3612 of the first shell 361 are arranged in sequence from top to bottom in the slide groove 162, so that the first shell 361, the first box body 301 and the support seat 311 can be slidably assembled along the slide groove 162. In addition, the flange on the other side of the first shell 361 and the support seat 311 is connected to the extension section 123 of the first grille 120 by screws, and the flange of the first box body 301 can be clamped with the first shell 361 through the support seat 311, so that the cleaning box 300 and the grille assembly 100 can be assembled into an integral structure.

[0154] It can be understood that the grille assembly 100 is assembled with the bracket 160 and the first grille 120, and the left grille member 121 and the right grille member 122 can be assembled by sliding horizontally; the grille assembly 100 and the cleaning box 300 are split structures, and the cleaning box 300 is assembled with the first box body 301, the second box body 302, the first shell 361 and the second shell 362, so that the multiple components of the filter cleaning module 1000 can be easily disassembled and replaced, and the maintainability is strong.

[0155] Reference Fig.16 As shown, the embodiment of the utility model further proposes an air-conditioning indoor unit 2000, specifically a wall-mounted air-conditioning indoor unit, including a chassis 600, a surface frame 700 and a filter cleaning module 1000 of the above embodiment, the surface frame 700 is installed on the chassis 600, and an air inlet 710 is opened on the top of the surface frame 700. The filter cleaning module 1000 can be detachably connected to the surface frame 700 so that the grille assembly 100 covers the air inlet 710; the filter cleaning module 1000 is an independent module structure, which can be disassembled and assembled as a whole, and maintenance and installation are more convenient, so that the filter cleaning module 1000 can be expanded to different model platforms, and has higher compatibility.

[0156] Reference Fig.17 and Fig.18 As shown, a volute 610 and a wind wheel (not shown in the drawings) are provided on the chassis 600, the volute 610 forms an air duct 611, and the air outlet 720 of the air duct 611 is located at the bottom of the surface frame 700, and the air conditioner indoor unit 2000 also includes a heat exchanger (not shown in the drawings), which is arranged between the filter cleaning module 1000 and the volute 610.

[0157] During normal operation, air enters the air conditioner indoor unit 2000 through the grille assembly 100 and the filter 200 from the air inlet 710, and then is discharged from the air outlet 720 of the air duct 611 after heat exchange in the heat exchanger, and the air can be filtered through the filter 200. When the filter 200 needs to be cleaned, the motor 410 drives the drum 420 to rotate, which can drive the filter 200 to rotate around the drum 420, so that different parts of the filter 200 can be immersed in the water tank 310 for cleaning, and the ultrasonic wave generated by the ultrasonic component 500 is transmitted to the water tank 310, so that the water in the water tank 310 is vibrated, and the high-frequency vibration will improve the cleaning efficiency, so that the filter 200 is cleaned more cleanly, and the filter 200 is automatically cleaned.

[0158] It should be noted that, in the embodiment, the cleaning box 300 is located at the front side of the face frame 700, which can make full use of the space at the front side of the air conditioner indoor unit 2000 without increasing the height and length of the fuselage; the front side of the face frame 700 is also provided with a panel 730, through which the cleaning box 300 can be shielded to prevent the cleaning box 300 from being exposed and affecting the appearance. In addition, when the filter 200 needs to be cleaned, water can be directly added to the water tank 310 by opening the panel 730, which is easy to operate, and the excess water can be discharged to the water tank through the overflow port 330, realizing fast water addition and anti-leakage and anti-overflow design.

[0159] The utility model also provides an air conditioner, including the air conditioner indoor unit 2000 of the above embodiment, the air conditioner indoor unit 2000 is installed with the filter cleaning module 1000 of the above embodiment, which can realize automatic cleaning of the filter 200, with high cleaning efficiency and high cleanliness.

[0160] Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
