[0049] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0050] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0051] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "front", "rear", "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the accompanying drawings. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.

[0052] In the description of the present invention, if terms such as "first", "second", etc. are described, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence of the indicated technical features.

[0053] In the description of the present invention, it should be noted that terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0054] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some, but not all, embodiments of the present invention.

[0055] During the long-term use of a wall-mounted air conditioner indoor unit, dust will accumulate on the filter screen at the air inlet, which is likely to breed bacteria and affect air quality. Therefore, it is necessary to clean the filter screen regularly. In the related art, a filter screen cleaning device is adopted for the wall-mounted air conditioner indoor unit. Usually, a brush and flushing water are used to clean the filter screen. This solution requires adding a water pumping motor and a solenoid valve, which has problems such as high cost, low assembly efficiency, and easy occurrence of failures. Moreover, the flushing process requires repeated operations to remove dust, the working procedure is complex, the working efficiency is low, and the cleaning effect is difficult to satisfy.

[0056] In addition, by installing the brush in the space where the filter screen is located, the filter screen cleaning device needs to increase the body size due to the need to drive the brush to move, which is likely to cause the body size to be too large to be acceptable to users. The solution has poor compatibility and high cost. Moreover, the overall structure of the filter screen cleaning device is complex, and the disassembly and assembly operations of the filter screen are cumbersome, which is not conducive to maintenance.

[0057] To solve the above problems, an embodiment of the present invention provides a filter cleaning module 1000, which is applicable to an air conditioner indoor unit 2000, specifically a wall-mounted air conditioner indoor unit. The following will refer to Figures 1 to 11 to introduce the filter cleaning module 1000 according to the embodiment of the present invention.

[0058] Referring to Figure 1 and Figure 4 As shown, the filter cleaning module 1000 provided by the embodiment of the present invention 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, and the installation space 110 is matched with the filter 200. 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. A water tank 301 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 301, so that the filter 200 can be cleaned by the water in the water tank 301.

[0059] Taking the application to the air conditioner indoor unit 2000 as an example for illustration, the filter cleaning module 1000 is installed on the front frame 700 of the air conditioner indoor unit 2000. The grille assembly 100 covers the air inlet 710 of the front frame 700. The grille assembly 100 can be understood as the installation structure of the filter 200. 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, such as a track, a guiding groove or other guiding structures. After the filter 200 is installed in place, when the air conditioner indoor unit 2000 operates, air will pass through the grille assembly 100 and the filter 200 and enter the interior. The air can be filtered by the filter 200. When the filter 200 needs to be cleaned, under the action of the driving assembly 400, the filter 200 can be guided into the water tank 301 for cleaning, and the filter 200 can be driven to move out of the water tank 301, so that the filter 200 can move back and forth between the installation space 110 and the water tank 301, and the dust accumulated on the filter 200 can be removed, realizing automatic cleaning of the filter 200.

[0060] Referring to Figure 1As shown, the grille assembly 100 is generally rectangular. An installation space 110 is formed inside the grille assembly 100. The cleaning box 300 and the drive 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 113 is provided on one side of the installation space 110 facing the cleaning box 300. The opening 113 is also arranged along the length direction of the grille assembly 100. The opening 113 allows the filter screen 200 to move into or out of the installation space 110, and the opening 113 is oppositely arranged with the notch of the water tank 301. That is to say, the installation space 110 communicates with the water tank 301 through the opening 113. The filter screen 200 can enter the installation space 110 from the opening 113 and can also enter the water tank 301 through the opening 113 for cleaning.

[0061] Among them, the drive assembly 400 may include a motor 410 and a transmission structure. The motor 410 drives the filter screen 200 to move through the transmission structure. For example, the transmission structure may be components such as rollers and gears. Taking the gear as an example, a rack is provided on the filter screen 200, and the gear meshes with the rack. By driving the gear to rotate through the motor 410, the filter screen 200 is driven to move.

[0062] Refer to Figure 2 and Figure 4 As shown, the filter screen cleaning module 1000 further includes an ultrasonic component 500. The ultrasonic component 500 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. By transmitting the ultrasonic waves into the water tank 301, the water in the water tank 301 can be made to generate high-frequency oscillations, which can accelerate the shedding of dirt such as dust from the filter screen 200. In this way, the filter screen 200 can be cleaned more cleanly, the cleaning efficiency can be improved, and the cleaning is more efficient and convenient.

[0063] It can be understood that the grille assembly 100 is assembled with the filter screen 200, the ultrasonic component 500 and the drive assembly 400 to form the entire module structure. That is to say, the filter screen cleaning module 1000 is an independent component, which is detachably assembled on the front frame 700 of the air conditioner indoor unit 2000. When assembling the air conditioner indoor unit 2000, after completing the assembly of the filter screen cleaning module 1000, the entire filter screen cleaning module 1000 can be installed on the front frame 700. The maintenance and installation are more convenient, the cost is reduced, and it can be compatible with different model platforms, which is beneficial to the expansion of the filter screen cleaning module 1000 on various model platforms and has higher compatibility.

[0064] Specifically refer to Figure 12As shown, it shows the air conditioner indoor unit 2000 of the embodiment. Among them, the air inlet 710 is located at the top of the front frame 700, and the filter screen cleaning module 1000 is embedded in the front 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 without affecting the appearance of the whole machine. Of course, the shape of the grille component 100 is not limited to a rectangle, and it can also be square, oval, etc. The specific size of the filter screen cleaning module 1000 can be designed according to the size of the air inlet 710.

[0065] Since the installation space 110 is formed inside the grille component 100 and the opening 113 of the installation space 110 is close to the cleaning box 300, after the filter screen 200 is removed from the opening 113 of the installation space 110 and enters the water tank 301, considering the limitations of the assembly structure, in order to facilitate the disassembly of the filter screen 200, the grille component 100 of the embodiment of the present invention adopts a detachable structure.

[0066] Refer to Figure 1 As shown, specifically, the grille component 100 includes a bracket 120 and a grille member 130. The grille member 130 is detachably connected to the bracket 120, so that an installation space 110 is formed between the grille member 130 and the bracket 120. In the embodiment, the grille member 130 is located at the top of the bracket 120, the grille member 130 is a grid structure, and at the same time, a grid structure is also provided at the position of the bracket 120 opposite to the grille member 130. The installation space 110 is located between the upper and lower grid structures. In this way, air can pass through the grid structure and enter the air conditioner indoor unit 2000 after being filtered by the filter screen 200. It can be understood that the filter screen 200 can be taken out after the grille member 130 is disassembled, the operation is simple, it is convenient to replace the filter screen 200, and it is also convenient to assemble the filter screen 200. The installation and maintenance of the filter screen cleaning module 1000 are more simple and fast.

[0067] It should be noted that the grille member 130 and the bracket 120 can be connected by means of snap connection, plug connection, screw connection, etc. For example, the grille member 130 is provided with a buckle, and the bracket 120 is provided with a slot, and they are fixed by the cooperation of the buckle and the slot. Specifically, it can be set according to application requirements.

[0068] Refer to Figure 3 and Figure 4As shown, the installation space 110 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 are spaced apart, and the first cavity 111 is located above the second cavity 112. The grille assembly 100 includes a first grille, a second grille 121, and a third grille 122. The first grille, the second grille 121, and the third grille 122 are sequentially spaced apart from top to bottom. Among them, the first grille is the grille member 130. A first cavity 111 is formed between the first grille and the second grille 121, and a second cavity 112 is formed between the second grille 121 and the third grille 122. The filter screen 200 can move back and forth between the first cavity 111 and the second cavity 112. Among them, the first cavity 111 can be understood as the upper track, and the second cavity 112 can be understood as the lower track.

[0069] It can be understood that the first cavity 111 and the second cavity 112 are connected through an opening 113. The filter screen 200 can slide out of the first cavity 111 and enter the second cavity 112, or can slide into the first cavity 111 from the second cavity 112. Both the first cavity 111 and the second cavity 112 are communicated with the water tank 301. Under the action of the driving assembly 400, the filter screen 200 slides out of the first cavity 111 and enters the water tank 301, and after being cleaned by the water tank 301, it enters the second cavity 112; then it slides into the water tank 301 from the second cavity 112, and after being cleaned by the water tank 301, it returns to the first cavity 111 again. Repeating the above operations can clean the filter screen 200 multiple times. Combining with the ultrasonic assembly 500 to oscillate the water in the water tank 301 makes the cleaning more efficient.

[0070] Refer to 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 beneficial to saving the assembly space of the grille assembly 100. The water tank 301 is located on the same side of the first cavity 111 and the second cavity 112. Through the first cavity 111 and the second cavity 112, the two ends of the filter screen 200 can be guided to move. As Figure 4 shows the state of the filter screen 200 during the moving process. One end of it is located in the first cavity 111, and the other end is located in the second cavity 112. That is to say, the two ends of the filter screen 200 can be separated from each other during the moving process without affecting each other, avoiding the filter screen 200 from bending and overlapping itself and increasing the resistance.

[0071] Considering that when the filter screen 200 moves back and forth between the first cavity 111 and the second cavity 112, it is necessary to bend and change the direction of the filter screen 200. In the embodiment, the filter screen 200 can be made of a flexible frame structure, which is convenient for the filter screen 200 to bend and slide in the first cavity 111 and the second cavity 112. For example, the frame of the filter screen 200 is made of flexible plastic material, which can be bent and has a certain strength.

[0072] It should be noted that the first grille, the second grille 121, and the third grille 122 all have a grid structure, facilitating the passage of air through the first cavity 111 and the second cavity 112. When the air conditioner indoor unit 2000 is operating normally, the filter screen 200 can be located in the first cavity 111 or the second cavity 112, thereby filtering the air through the filter screen 200. Since the first grille is detachably connected to the bracket 120, it is convenient to take out the filter screen 200 from the first cavity 111. During assembly, the filter screen 200 only needs to be placed in the first cavity 111. In some embodiments, the second grille 121, the third grille 122, and the bracket 120 are integrally injection-molded, facilitating the assembly of the grille assembly 100 and making the structure more stable.

[0073] Referring Figure 1 and Figure 4 As shown, the cleaning box 300 is provided 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, combined with Figure 12 it can be understood that in order to enable the filter screen cleaning module 1000 to be matched and installed on the air conditioner indoor unit 2000, in the embodiment, the cleaning box 300 is located on the front side of the grille assembly 100. When the filter screen cleaning module 1000 is installed on the air conditioner indoor unit 2000, the cleaning box 300 is located on the front side of the air conditioner indoor unit 2000. In this way, the space on the front side of the air conditioner indoor unit 2000 can be fully utilized, the structural design is reasonable, and the smooth movement of the filter screen 200 is realized.

[0074] In some embodiments, the filter screen 200 includes a first filter element and a second filter element. That is to say, the filter screen 200 is divided into two parts. Taking Figure 1 the shown direction as the reference direction, the first filter element can be understood as the left filter screen 200, and the second filter element can be understood as the right filter screen 200. A first installation space 110 and a second installation space 110 are formed in the grille assembly 100. The first filter element is movably installed in the first installation space 110, and the second filter element is movably installed in the second installation space 110 to realize the assembly of the first filter element and the second filter element.

[0075] It can be understood that the first installation space 110 and the second installation space 110 are respectively provided with openings 113, and both openings 113 face the water tank 301. In this way, the first filter element can enter the water tank 301 from the first installation space 110 for cleaning, and the second filter element can enter the water tank 301 from the second installation space 110 for cleaning, and the left and right filter screens 200 can be cleaned simultaneously.

[0076] Referring Figure 1As shown, in some embodiments, the grille member 130 includes a first grid portion 131 and a second grid portion 132. The top of the bracket 120 is provided with a first mounting position 127 and a second mounting position 128, and the first mounting position 127 and the second mounting position 128 are spaced along the length direction of the bracket 120. The first grid portion 131 is slidably connected within the first mounting position 127, and the second grid portion 132 is slidably connected within the second mounting position 128, so that the first grid portion 131 and the second grid portion 132 are respectively detachably connected to the bracket 120. The first grid portion 131 can be understood as the left grille, and the second grid portion 132 can be understood as the right grille, that is, the first grid portion 131 covers the first filter element, and the second grid portion 132 covers the second filter element. In this way, both the first filter element and the second filter element can be disassembled and assembled separately, and the operation is simple.

[0077] It can be understood that the first installation space 110 and the second installation space 110 respectively include the first cavity 111 and the second cavity 112 of the above embodiments, and the two installation spaces 110 respectively have a second grille 121 and a third grille 122. Taking the first installation space 110 as an example for illustration, combined with Figure 4 It can be understood that the first installation space 110 includes a first cavity 111 and a second cavity 112. The first grid portion 131, the second grille 121, and the third grille 122 are arranged in sequence from top to bottom. A first cavity 111 is formed between the first grid portion 131 and the second grille 121, and a second cavity 112 is formed between the second grille 121 and the third grille 122. Among them, the first grid portion 131 is a detachable structure, which is convenient for removing the first filter element.

[0078] Under the driving action of the driving assembly 400, the first filter element moves out of the first cavity 111 along the opening 113 and enters the water tank 301 for cleaning. After passing through the water tank 301, it enters the second cavity 112. It can also be moved from the second cavity 112 into the water tank 301, and after being cleaned by the water tank 301, it enters the first cavity 111. In this way, driving the first filter element to move back and forth can perform multiple cleanings, and ultrasonic waves are generated by the ultrasonic assembly 500 to cause the water in the water tank 301 to oscillate at a high frequency, so as to improve the cleaning efficiency and make the cleaning of the first filter element cleaner.

[0079] Refer to Figure 1 、 Figure 3 and Figure 7As shown, it should be noted that both the first filter element and the second filter element are driven by the drive assembly 400. In the embodiment of the present invention, the drive assembly 400 includes a first roller 430, a second roller 440, and a driver. The cleaning box 300 includes a first box body 310 and a second box body 320. Among them, the first box body 310 corresponds to the first installation space 110. The first roller 430 extends along the length direction of the first box body 310. Both ends of the first roller 430 are rotatably connected inside the first box body 310. The first roller 430 is connected to the first filter element. The motor 410 drives the first roller 430 to rotate, which can drive the filter screen 200 of the first filter element to move around the first roller 430, so that the first filter element moves along the first cavity 111 and the second cavity 112 in the first installation space 110.

[0080] The second box body 320 corresponds to the second installation space 110. The second roller 440 extends along the length direction of the second box body 320. Both ends of the second roller 440 are rotatably connected inside the second box body 320. The second roller 440 is connected to the second filter element. The motor 410 drives the second roller 440 to rotate, which can drive the filter screen 200 of the second filter element to move around the second roller 440, so that the second filter element moves along the first cavity 111 and the second cavity 112 in the second installation space 110. It should be noted that the first roller 430 and the second roller 440 are driven by the same driver and can operate synchronously, so as to drive the first filter element and the second filter element to be cleaned synchronously.

[0081] Taking the first roller 430 and the first filter element as an example for illustration, the outer peripheral wall of the first roller 430 and the first filter element can be in contact through the connection method of transmission gears. For example, the outer peripheral wall of the first roller 430 is provided with teeth, and the first filter element is provided with a tooth portion meshing with the teeth. In this way, when the first roller 430 rolls, it can drive the first filter element to move, making the first filter element not easily shift and operate more stably. Moreover, the motor 410 can drive the first roller 430 to rotate forward or backward, so that the first filter element can slide from the first cavity 111 to the second cavity 112, or slide from the second cavity 112 to the first cavity 111, achieving the purpose of cleaning the filter screen 200 back and forth.

[0082] Combined with Figure 6 and Figure 7It can be understood that the driver is fixedly connected to the middle position of the bracket 120. In the embodiment, the driver is the motor 410. The drive assembly 400 further includes a transmission gear set 420 and a transmission shaft 450. A support 124 is formed at the middle position of the bracket 120. The support 124 is located between the first installation position 127 and the second installation position 128, and separates the first box body 310 from the second box body 320 through the support 124. The support 124 is provided with an installation cavity, and the installation cavity is located between the first box body 310 and the second box body 320. The transmission gear set 420 is rotatably connected in the installation cavity, so that the drive assembly 400 can be isolated from water, and the size of the water tank 301 is not affected by the transmission gear set 420. In the embodiment, the transmission gear set 420 has three gears. The motor 410 is located outside the installation cavity. The motor 410 is connected to one of the gears through a drive shaft. The transmission shaft 450 is connected to the gear far from the motor 410. The two ends of the transmission shaft 450 respectively pass through the first box body 310 and the second box body 320 and are connected to the first roller 430 and the second roller 440. In this way, the motor 410 drives the transmission gear set 420 to operate, drives the transmission shaft 450 to rotate through the transmission gear set 420, so that the transmission shaft 450 can drive the first roller 430 and the second roller 440 to rotate synchronously. The transmission shaft 450 and the first roller 430 and the second roller 440 can be connected by direct coupling, coupling and other methods, so as to realize that one motor 410 can drive two rollers to rotate at the same time.

[0083] It can be understood that since the drive assembly 400 is installed in the middle position of the bracket 120 and drives two rollers to rotate at the same time, the forces on the two rollers can be more uniform, the rotation consistency is better, and the movement of the first filter element and the second filter element is more stable. In addition, it can also save length space, that is to say, the drive assembly 400 will not increase the overall length of the filter screen cleaning module 1000, which is convenient for 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 meter, reducing the wiring cost.

[0084] It should be noted that in the embodiment, the sizes of the first box body 310 and the second box body 320 can meet the requirements of accommodating the first roller 430 and the second roller 440, and respectively drive the first filter element and the second filter element to enter the water tank 301 for cleaning. It can be understood that the greater the depth of the water tank 301, the larger the area where the filter screen 200 enters the water tank 301, the more the water level soaks the filter screen 200, and the better the cleaning effect, so that the filter screen 200 can be cleaned to the greatest extent. Combined with the ultrasonic component 500 to generate oscillation in the water in the water tank 301, the cleaning is cleaner and more efficient; compared with the cleaning method of brush and water flushing, it can prevent dust from flying, has a higher cleaning cleanliness and lower cost.

[0085] It should be noted that the first cavity 111 and the second cavity 112 in the embodiments of the present invention not only have a guiding effect on the filter screen 200, but also can serve as the installation space 110 for the filter screen 200. Only one motor 410 and two drums are required to meet the driving requirements, realizing the back-and-forth rolling cleaning of the first filter element and the second filter element, simplifying the structure, reducing the material cost and improving the production efficiency. Moreover, while reducing the cost, the reliability of the filter screen cleaning module 1000 can also be improved.

[0086] Referring to Figure 7 As shown, it can be understood that the drive assembly 400 further includes bearings, which support the transmission shaft 450 through the bearings, making the operation of the transmission shaft 450 more stable. Considering that the transmission shaft 450 needs to pass through the cleaning box 300 and be connected to the two drums, in some embodiments, a waterproof ring 460 is provided at the bearing, and the waterproof ring 460 can prevent the water in the water tank 301 from flowing out through the gap between the transmission shaft 450 and the cleaning box 300, increasing the waterproof sealing performance.

[0087] Specifically, since both ends of the transmission shaft 450 pass through the first box body 310 and the second box body 320 respectively, there are two bearings, which respectively support both ends of the transmission shaft 450, and waterproof rings 460 are respectively provided at the bearings at both ends, so as to improve the waterproof performance of the first box body 310 and the second box body 320. Among them, the waterproof ring 460 can be a silicone sealing ring or other forms of sealing rings, and the number of the waterproof rings 460 is not limited to one. Two or more waterproof rings 460 can also be provided at the same bearing to improve the sealing performance.

[0088] It can be understood that since the first grid portion 131 and the second grid portion 132 are respectively slidably connected to the first installation position 127 and the second installation position 128, in the embodiments of the present invention, a limiting structure is added to limit the first grid portion 131 and the second grid portion 132 to ensure that the first grid portion 131 and the second grid portion 132 are not easily separated from the bracket 120 after being installed in place. The following uses specific examples to illustrate the limiting structure of the first grid and the second grid.

[0089] Referring to Figure 8 As shown, the grille assembly 100 further includes a first limiting member 140. The first grid portion 131 is provided with a first limiting rib 1311. The first limiting rib 1311 is located on the side of the first grid portion 131 close to the cleaning box 300 and extends along the length direction of the first grid portion 131; the first limiting member 140 is specifically strip-shaped, and a first clamping groove 141 is provided on the first limiting member 140, and the first clamping groove 141 extends along the length direction of the first limiting member 140.

[0090] It can be understood that guide grooves 129 are formed on both sides of the first installation position 127, facilitating the first grid portion 131 to slide into the first installation position 127 along the guide grooves 129. During assembly, when the first grid portion 131 is introduced into the first installation position 127 in a flat-pushing manner, the two ends of the first limiting member 140 are respectively snapped into the guide grooves 129 on both sides, and at the same time, the first limiting rib 1311 is inserted into the first card slot 141 for limiting cooperation, which can prevent the first grid portion 131 from loosening.

[0091] Combined with Figure 4 It can be understood that the first limiting rib 1311 is located at the end of the first grid portion 131, and the first card slot 141 is arranged facing the first grid portion 131. The cooperation between the first limiting rib 1311 and the first card slot 141 can prevent the first grid portion 131 from shaking up and down, and the structure is more stable and reliable.

[0092] It should be noted that in the embodiment, a groove is provided on one side of the support 124 facing the first installation position 127. One end of the first limiting member 140 can be inserted into the groove for fixation, and the other end can be fixedly connected to the bracket 120 through a screw. Thus, the first grid portion 131 can be fixed with just one screw, and the assembly is convenient. In some embodiments, the first grid portion 131 is fixed to the bracket 120 by a snap-fastening method. However, the snap-fastening method has problems such as difficult disassembly and long disassembly time. Compared with the snap-fastening method, Figure 8 using the first limiting member 140 in the shown embodiment to fix the first grid portion 131 is more convenient for disassembly, facilitates installation and maintenance, and is beneficial to cost reduction.

[0093] Referring to Figure 9 As shown, the grille assembly 100 further includes a second limiting member 150. The second grid portion 132 is provided with a second limiting rib 1321. The second limiting rib 1321 is arranged on the side of the second grid portion 132 away from the first grid portion 131 and extends along the width direction of the second grid portion 132. The second limiting member 150 is specifically in a long strip shape, and a second card slot (not shown in the drawings) is provided on the second limiting member 150, and the second card slot extends along the length direction of the second limiting member 150.

[0094] It can be understood that in the embodiment, guide grooves 129 are formed on both sides of the second installation position 128. The second grid portion 132 is moved into the second installation position 128 through the guide grooves 129. A slot matching the second limiting member 150 is formed on the side of the second installation position 128 away from the first installation position 127, enabling the second limiting member 150 to be assembled into the second installation position 128. The second limiting rib 1321 and the second card slot cooperate for limiting, which can prevent the second grid portion 132 and the second limiting member 150 from loosening and prevent the second grid from shaking up and down, and the structure is stable and reliable.

[0095] It should be noted that in the embodiment, the second limiting member 150 can be fixedly connected to the bracket 120 by a screw, which is convenient for assembly. When disassembling, the second grid portion 132 and the second limiting member 150 can be moved out of the second installation position 128 along the guiding groove 129 together. Compared with the fixing method of the buckle, the structure is simplified, the disassembly is more convenient, which is convenient for installation and maintenance, and is beneficial to cost reduction.

[0096] In addition, in the embodiment, both the first grid portion 132 and the second grid portion 150 are loaded onto the bracket 120 by a flat-pushing method, and accurate positioning installation is not required, and the installation operation is simple. Moreover, the first limiting member 140 and the second limiting member 150 adopt different installation methods, which has the function of preventing misoperation and is convenient for installation. Of course, this is only an example here, and the installation positions of the first limiting member 140 and the second limiting member 150 are not limited to the structures shown in the above embodiments. For example, the first limiting member 140 is arranged on the left side of the first grid portion 131, and the second limiting member 150 is arranged on the front side of the second grid portion 132.

[0097] Referring to Figure 8 and Figure 9 As shown, the first grid portion 131 and the second grid portion 132 are respectively provided with extension segments 133, the extension segments 133 are arranged towards the cleaning box 300, and the first grid portion 131 and the second grid portion 132 are respectively detachably connected to the cleaning box 300 through the extension segments 133. The extension segment 133 can be understood as a bending segment 123 formed by bending the first grid portion 131 and the second grid portion 132 downward.

[0098] In some embodiments, the extension segment 133 is connected to the cleaning box 300 by a screw, which is convenient for installation and disassembly. And by connecting with the cleaning box 300 through the extension segment 133, the reliability of the first grid portion 131 and the second grid portion 132 is further improved. After being installed in place, the extension segment 133 covers the notch position of the water tank 301, which can prevent the first roller 430 and the second roller 440 from detaching from the cleaning box 300.

[0099] Referring to Figure 8As shown in the figure, a first limiting groove 1312 is provided on the side of the first grid part 131 away from the cleaning box 300. The first limiting groove 1312 is formed on the frame structure of the first grid part 131. A first limiting buckle 1271 is provided on the bracket 120. The first limiting buckle 1271 is formed at the peripheral wall position of the first installation position 127. Specifically, it can be a convex block or a convex rib, etc., protruding from the top of the peripheral wall and located at the corner position of the first installation position 127. The first limiting groove 1312 is a concave structure formed on the upper surface of the first grid part 131. The first limiting buckle 1271 matches the first limiting groove 1312. When the first grid part 131 is pushed flat into the first installation position 127, the first limiting buckle 1271 is inserted into the first limiting groove 1312. In this way, the first grid part 131 can be pressed tightly by the first limiting buckle 1271, so that the first grid part 131 can be limited.

[0100] It should be noted that in the embodiment, the first installation position 127 is generally rectangular. The first limiting buckle 1271 can be arranged at the two corner positions on the side of the first installation position 127 away from the cleaning box 300, so that the two corners of the first grid part 131 can be limited at the same time. Since the first limiting member 140 and the first limiting rib 1311 limit the front side of the first grid part 131, and the first limiting buckle 1271 and the first limiting groove 1312 cooperate to limit the rear side of the first grid part 131, both the front and rear sides of the first grid part 131 are limited, the disassembly and assembly are simple, and the situation that the first grid part 131 moves up and down and disengages from the bracket 120 is effectively prevented, and the structure is more stable and reliable.

[0101] Refer to Figure 9 As shown in the figure, a second limiting groove is provided on the side of the second grid part 132 away from the cleaning box 300. The second limiting groove is formed on the frame structure of the second grid part 132. A second limiting buckle 1281 is provided on the bracket 120. The second limiting buckle 1281 is formed at the peripheral wall position of the second installation position 128. The second limiting buckle 1281 matches the second limiting groove. When the second grid part 132 is pushed flat into the second installation position 128, the second limiting buckle 1281 is inserted into the second limiting groove, so that the second grid part 132 can be limited. The assembly structure of the second limiting buckle 1281 and the second limiting groove can specifically refer to Figure 8 the structure of the first limiting buckle 1271 and the first limiting groove 1312 shown in

[0102] It should be noted that the second limiting member 150 and the second limiting rib 1321 limit the right side of the second grid part 132, and the second limiting buckle 1281 and the second limiting groove cooperate to limit the rear side of the second grid part 132, so that different sides of the second grid part 132 are limited, and the situation that the second grid part 132 moves up and down and disengages from the bracket 120 is effectively prevented, and the assembly is more stable and reliable.

[0103] Continue to refer to Figure 4 As shown, since the cleaning box 300 is located at the lower front side of the grille assembly 100, the space in front of the air conditioner indoor unit 2000 can be utilized. To match the position of the cleaning box 300, the first grille, the second grille 121, and the third grille 122 are all bent to form a bent section 123, so that the first grille, the second grille 121, and the third grille 122 respectively extend to the position of the water tank 301. In this way, the first cavity 111 and the second cavity 112 can communicate with the water tank 301, and the front part of the grille assembly 100 does not affect the size of the whole machine. It should be noted that the extended section 133 of the first grille can be understood as the bent section 123 of the first grille.

[0104] Since the cleaning box 300 is located at the front side of the air conditioner 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 both the left and right sides of the air conditioner indoor unit 2000, which can reduce the length dimension of the fuselage and is more acceptable to users.

[0105] Refer to Figure 2 As shown, the first box body 310 and the second box body 320 are both metal parts. In the embodiment, the first box body 310 and the second box body 320 are respectively made of sheet metal parts. The ultrasonic component 500 includes two ultrasonic vibrating sheets 510, and the two ultrasonic vibrating sheets 510 are respectively connected to the bottoms of the first box body 310 and the second box body 320. The ultrasonic wave is transmitted through the sheet metal part, so that the water in the water tank 301 can have a large enough oscillation frequency, thereby effectively cleaning the filter screen 200.

[0106] Of course, this is only an example here. The number of ultrasonic vibrating sheets 510 on each box body is not limited to one, and can also be two or more. Two or more ultrasonic vibrating sheets 510 can be connected in parallel or in series, and the specific connection method is selected according to the actual application.

[0107] It should be noted that the ultrasonic vibrating sheet 510 is a piezoelectric element that converts electrical energy into mechanical energy. It is composed of a piezoelectric ceramic material and a metal electrode. When an electric field is applied, the piezoelectric material will have a piezoelectric effect, thereby generating mechanical vibration and forming ultrasonic waves. Ultrasonic waves have the characteristics of short wavelength and high frequency. Through the metal layer of the cleaning box 300, high-frequency oscillation can be generated, so that the water in the water tank 301 oscillates. The high-frequency oscillation of water molecules will wash the dust on the filter screen 200, realizing the rapid cleaning of the filter screen 200, which is cleaner than the method of cleaning with a brush.

[0108] In addition, the ultrasonic vibrating sheet 510 is rectangular, and the two ultrasonic vibrating sheets 510 are respectively arranged along the length direction of the first box body 310 and the second box body 320. It can be understood that each box body uses a single ultrasonic vibrating sheet 510 to generate ultrasonic waves. Compared with the structure of two or more ultrasonic vibrating sheets 510, the single ultrasonic vibrating sheet has a greater length. In this way, a single ultrasonic vibrating sheet 510 can be used to replace two or more ultrasonic vibrating sheets 510 with smaller sizes, reducing costs and improving the cleaning rate. In terms of cost savings, it mainly reduces the assembly cost, material cost, and electronic control cost. The reason is that the cost of a single ultrasonic vibrating sheet 510 is equivalent to half of the cost of two sheets, the installation efficiency is higher, and the power supply cost also drops by 1 / 3.

[0109] It should be noted that since the parallel or series operation of two or more ultrasonic vibrating sheets 510 will cause the electronic control cost to increase exponentially, the embodiment of the present invention is optimized to use a high-power single-piece ultrasonic vibrating sheet 510. Taking the first box body 310 as an example, the ultrasonic vibrating sheet 510 is arranged at the middle position of the first box body 310, so as to achieve an effective cleaning effect while reducing the electronic control cost.

[0110] Refer to Figure 1 As shown, in some embodiments, the cleaning box 300 further includes an insulating housing 330. The insulating housing is made of plastic, silicone, or other insulating materials. Taking the plastic insulating housing 330 as an example, the insulating housing 330 can be an integral structure, covering the outside of the first box body 310 and the second box body 320. The plastic housing has an insulating and protective effect, preventing the sheet metal parts from being exposed and preventing the generated ultrasonic waves from hurting people.

[0111] Refer to Figure 10 and Figure 11 As shown, in some embodiments, the insulating housing 330 includes a first housing portion 331 and a second housing portion 332, that is, the insulating housing 330 adopts a split structure. Among them, the first housing portion 331 is used to cover the first box body 310, and the second housing portion 332 is used to cover the second box body 320. In the embodiment, the length of the first box body 310 and the second box body 320 is the same as that of the first housing portion 331 and the second housing portion 332. The bracket 120 is provided with a snap 126 and a chute 125. Slots are respectively arranged on the opposite sides of the first housing portion 331 and the second portion. The snap 126 is located at the middle position of the bracket 120, and the chute 125 extends along the left-right direction of the cleaning box 300. The first housing portion 331 and the second housing portion 332 can slide along the chute 125. Through the guiding action of the chute 125, the first housing portion 331 and the second housing portion 332 can be spliced relatively to form the insulating housing 330. The snap 126 and the slot are cooperated for buckling, so as to fix the first housing portion 331 and the second housing portion 332, and the assembly is simple.Figure 10 and Figure 11 shows the installation state where the first housing 331 is assembled in place and the second housing 332 moves along the sliding groove 125.

[0112] Specifically, the first housing 331 and the second housing 332 are respectively provided with open ports. The port of the first housing 331 is arranged opposite to the port of the second housing 332. When the first housing 331 and the second housing 332 are assembled in place along the sliding groove 125, the two ports can abut against each other, so that the first housing 331 and the second housing 332 are spliced to form the insulating housing 330, and are fixed by the cooperation of the snap 126 and the slot.

[0113] Combined with Figure 7 it can be understood that the snap 126 is arranged at the bottom of the support 124 and protrudes from the bottom surfaces of the first box body 310 and the second box body 320. The snap 126 extends towards both sides to form a first insertion end 1261 and a second insertion end 1262. One end of the first housing 331 facing the second housing 332 is provided with a first slot 3311, and one end of the second housing 332 facing the first housing 331 is provided with a second slot 3321. The first insertion end 1261 is engaged with the first slot 3311, and the second insertion end 1262 is engaged with the second slot 3321 to realize the fixation of the first housing 331 and the second housing 332. Taking the first housing 331 and the first slot 3311 as an example, the first housing 331 moves along the sliding groove 125 towards the first housing 331. When approaching the position of the second housing 332, the first insertion end 1261 can be inserted into the first slot 3311 for engagement, so as to achieve the purpose of fixing the first housing 331.

[0114] It can be understood that the splicing of the first housing 331 and the second housing 332 can be realized through the cooperation of the snap 126 and the slot, and it is also convenient for disassembly, so that the first housing 331 and the second housing 332 can be quickly detached from the cleaning box 300. The snap 126 and the slot have different connection forms, and their design can fix the opposite ends of the first housing 331 and the second housing 332 to prevent them from moving up and down and left and right. In the production process, the above installation method can effectively improve the installation efficiency and save the cost of structural parts. The specific forms of the snap 126 and the slot can be selected according to application requirements.

[0115] It should be noted that, combined with Figure 4 and Figure 5As shown, the first housing portion 331 can be smoothly inserted along the sliding groove 125, which also effectively prevents misinsertion and enables the first housing portion 331 to be accurately assembled in place. In addition, in some embodiments, the first housing portion 331 and the second housing portion 332 can be respectively connected to the bracket 120 by screws. Specifically, the screw connection positions can be set away from the end of the snap 126. In this way, the first housing portion 331 and the second housing portion 332 can respectively achieve the purpose of fixation by using one screw, improving the installation efficiency.

[0116] In addition, since the insulating housing 330 wraps around the outside of the first box body 310 and the second box body 320, when water overflows or leaks from the first box body 310 and the second box body 320, the insulating housing 330 can prevent the water from further flowing to the outside of the cleaning box 300, avoiding water leakage of the cleaning box 300 and improving the product reliability.

[0122] During normal operation, air enters the interior of the air conditioner indoor unit 2000 from the air inlet 710 through the grille assembly 100 and the filter screen 200, and then is discharged from the air outlet 720 of the air duct 611 after heat exchange by the heat exchanger. The air can be filtered by the filter screen 200. When the filter screen 200 needs to be cleaned, the first roller 430 and the second roller 440 are driven to rotate by a driver, which can drive the filter screen 200 to roll, so that different parts of the filter screen 200 can be immersed in the water tank 301 for cleaning. And by transmitting the ultrasonic waves generated by the ultrasonic component 500 to the water tank 301, the water in the water tank 301 can be made to oscillate. The high-frequency oscillation will improve the cleaning efficiency, make the filter screen 200 cleaner, and realize automatic cleaning of the filter screen 200.

[0123] Since the grille member 130 and the bracket 120 are connected in a detachable manner, it is convenient to disassemble the grille member 130 and take out the filter screen 200, and it is also convenient to assemble the filter screen 200, making the installation and maintenance of the filter screen cleaning module 1000 simpler and improving the disassembly and assembly efficiency of the air conditioner indoor unit 2000.

[0124] It should be noted that in the embodiment, the cleaning box 300 is located on the front side of the front frame 700, which can make full use of the space on the front side of the air conditioner indoor unit 2000 without increasing the height and length dimensions of the fuselage. A panel is also provided on the front side of the front frame 700, through which the cleaning box 300 can be blocked to prevent the cleaning box 300 from being exposed and affecting the appearance.
