[0037] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0038] like Figure 7 and Figure 8 As shown in the figure, this application embodiment provides a filtration device 100, including: a filter support 1, a filter 2, and a cleaning assembly 3.

[0039] The filter support 1 is provided with a detachable connection part. The detachable connection part is configured to be detachably connected to the housing of the air conditioner, so that the filter device 100 is detachably connected to the housing.

[0040] Filter screen 2 is installed on filter screen bracket 1.

[0041] The cleaning component 3 is installed on the filter support 1 and is configured to clean the filter 2.

[0042] The filter device 100 provided in this embodiment of the application is equipped with a cleaning component 3, which can be used to clean the filter screen 2. This helps to improve the problem of dust accumulation on the filter screen 2 leading to clogging and bacterial growth, without requiring the user to remove the filter screen 2 separately for manual cleaning, thus improving the user experience. Furthermore, the filter device 100 is detachably connected to the air conditioner housing, making it convenient for the user to remove the entire filter device 100 for inspection, replacement, and other operations.

[0043] In some exemplary embodiments, the detachable connection includes a plug-in portion and a fixing portion. The plug-in portion is configured to plug into the housing, and the fixing portion is configured to be connected to the housing via fasteners. The fasteners may be, but are not limited to, screws.

[0044] During installation, simply insert the connector of the filter device 100 into the housing, then install the fasteners to mount the filter device 100 onto the housing. For disassembly, remove the fasteners and then pull out the filter device 100; the process is very convenient and quick.

[0045] In some exemplary embodiments, such as Figure 8 As shown, the insertion part is located at one end of the filter support 1 facing away from the air conditioner (i.e., the rear end), and the fixing part is located at one end of the filter support 1 facing the air conditioner (i.e., the front end).

[0046] In other words, the insertion part is located at the rear end of the filter screen bracket 1, and the fixing part is located at the front end of the filter screen bracket 1. This provides more operating space for the installation of fasteners, making it easier for operators to install fasteners quickly and smoothly.

[0047] In some exemplary embodiments, such as Figure 8 As shown, the insertion part includes a plurality of spaced-apart snaps 14. Correspondingly, the housing is provided with a plurality of insertion holes 41, such as... Figure 6 As shown. Multiple snap fasteners 14 and multiple insertion holes 41 are matched one by one, which can realize the insertion and matching of multiple parts of the filter device 100 and the housing, which helps to improve the positioning reliability of the filter device 100 and the housing.

[0048] The fixing part includes a plurality of fixing holes 15 spaced apart, such as Figure 8 As shown. Accordingly, the housing is provided with multiple connection holes 42, such as... Figure 6 As shown, multiple fixing holes 15 and multiple connecting holes 42 are fixedly connected by multiple fasteners, which helps to improve the connection reliability between the filter device 100 and the housing.

[0049] In some exemplary embodiments, such as Figure 8 As shown, the filter support 1 includes a first support 11, a second support 12, and a third support 13 stacked together. The first support 11 and the second support 12 together form a first guide groove 161, and the second support 12 and the third support 13 together form a second guide groove 162, as shown. Figure 4 As shown. The portions of the first bracket 11, the second bracket 12, and the third bracket 13 corresponding to the filter screen 2 can be configured as a grid, such as... Figure 8 As shown.

[0050] The cleaning component 3 is located at one end along the length of the filter support 1. The height of the cleaning component 3 is greater than the thickness of the filter support 1, resulting in an L-shaped overall layout of the filter device 100. Figure 7 As shown. For wall-mounted air conditioner indoor units, the filter device 100 can be placed on the top and left side of the casing, which helps to reduce the space occupied by the filter device 100 inside the casing.

[0051] like Figure 4 and Figure 8 As shown, the cleaning assembly 3 includes a roller 32, a brush 33, and a drive mechanism 31. The drive mechanism 31 is configured to drive the roller 32 to rotate. The roller 32 is in transmission cooperation with the filter screen 2, and the filter screen 2 is a flexible part, so that the filter screen 2 can pass around the roller 32 under the drive of the roller 32 and reciprocate between the first guide groove 161 and the second guide groove 162. The brush 33 is configured to clean the part of the filter screen 2 that passes through the roller 32.

[0052] The first guide groove 161 and the second guide groove 162 allow the filter screen 2 to move within the filter screen support 1, so that dust on the filter screen 2 can be swept off by the brush 33. When the filter device 100 is in normal use, at least a portion of the filter screen 2 is located within the first guide groove 161 (e.g., ...). Figure 5 The filter screen 2 is located on the upper side to filter the airflow entering the housing. When the filter screen 2 needs cleaning, the drive mechanism 31 drives the roller 32 to rotate, causing the roller 32 to move the filter screen 2 towards the second guide groove 162 (as shown). Figure 5 (The filter screen is located on the lower side). During the movement of the filter screen 2, the filter screen 2 will come into contact with the brush 33 through friction, causing the dust on the filter screen 2 to be swept off by the brush 33.

[0053] The drive mechanism 31 may include a drive element (such as a motor). The drive mechanism 31 may also include a transmission mechanism (such as a gear transmission mechanism).

[0054] like Figure 4As shown, the brush 33 can be located below the roller 32. The brush 33 can be rotatably supported on the filter support 1 via the rotating shaft 3421. When the filter 2 moves and comes into contact with the brush 33 through friction, it can drive the brush 33 to rotate together, thereby enabling all parts of the brush 33 in the circumference to participate in the cleaning process and improve cleaning efficiency.

[0055] The roller 32 can be provided with teeth, and the filter screen 2 can be provided with a meshing part 21 that meshes with the teeth, such as... Figure 4 As shown. In this way, roller 32 can rotate in both directions, driving filter 2 to move in both directions. Alternatively, filter 2 can be connected to a conveyor belt, with the conveyor belt tensioned on roller 32.

[0056] In some exemplary embodiments, the first bracket 11 and the third bracket 13 are snap-fitted together, the second bracket 12 is sandwiched between the first bracket 11 and the third bracket 13, and a detachable connecting part is provided on the third bracket 13. In this way, the installation process of the filter bracket 1 is simple and quick.

[0057] For example, such as Figure 8 As shown, the first bracket 11 has buckles 112 at both ends in the width direction, the third bracket 13 has locking holes 132 at both ends in the width direction, and the second bracket 12 has positioning grooves 121 at both ends in the width direction. The buckles 112 of the first bracket 11, the positioning grooves 121 of the second bracket 12, and the locking holes 132 of the third bracket 13 are corresponding. The buckles 112 pass through the positioning grooves 121 and engage with the corresponding locking holes 132. In this way, the first bracket 11 and the third bracket 13 are connected by a snap-fit, and the buckles 112 and the positioning grooves 121 provide a positioning and limiting function for the second bracket 12, which helps to improve the positional stability of the first bracket 11, the second bracket 12, and the third bracket 13, thereby improving the reliability of the filter support 1.

[0058] In some exemplary embodiments, such as Figure 4 and Figure 8 As shown, one end of the third bracket 13 along its length is provided with a mounting base 131, and the cleaning component 3 is mounted on the mounting base 131. One end of the first bracket 11 along its length is provided with a mounting cover 111. The mounting base 131 is provided with a mounting cavity 1311, and the end of the mounting cavity 1311 facing the mounting cover 111 is provided with a mounting opening 1312 (e.g., ...). Figure 9 As shown), this allows the brush 33 and roller 32 to be installed into the mounting base 131 from top to bottom.

[0059] The mounting cover 111 seals the mounting opening 1312 and, together with the mounting base 131, forms a third guide groove 163 that connects the first guide groove 161 and the second guide groove 162. Figure 4As shown. The first guide groove 161, the third guide groove 163, and the second guide groove 162 are connected in sequence to form a U-shaped guide groove, ensuring that the filter screen 2 can reciprocate between the first guide groove 161 and the second guide groove 162.

[0060] like Figure 2 , Figure 8 and Figure 10 As shown, the cleaning assembly 3 also includes a dust collection box 34 detachably installed in the mounting cavity 1311. The top of the dust collection box 34 is open and located below the brush 33, configured to collect dust swept by the brush 33. The dust collection box 34 can collect dust, preventing dust from flying and polluting the air. Furthermore, the dust collection box 34 can be removed for easy emptying of the collected dust.

[0061] Mounting base 131 and third bracket 13 can be an integral structure or a separate assembly structure. Mounting cover 111 and first bracket 11 can be an integral structure or a separate assembly structure. Mounting cover 111 and mounting base 131 can be connected by the engagement of buckle 112 and buckle hole 132, or by fasteners or other connection methods.

[0062] The volume of the dust collection box 34 can be designed based on the dust accumulation data of the filter under long-term operating conditions in the home environment (such as more than 1 year). The volume can meet the needs of a regular air conditioner for more than a year, so as to avoid frequent dust emptying during daily use.

[0063] The drive mechanism 31 can be installed at the rear of the mounting base 131. The rear of the dust collection box 34 can be provided with clearance to allow the drive mechanism 31 to pass.

[0064] In some exemplary embodiments, such as Figure 9 As shown, the opposite side walls of the mounting cavity 1311 are provided with a first elastic fastener 1313 and a second elastic fastener 1314. The dust collection box 34 is sandwiched between the first elastic fastener 1313 and the second elastic fastener 1314 to limit the dust collection box 34 from vibration and loosening. This helps to improve the positional stability of the dust collection box 34 during use.

[0065] The first elastic buckle 1313 and the second elastic buckle 1314 can undergo elastic deformation, which makes it easy for users to disassemble and install the dust collection box 34 separately. The reset elastic force of the first elastic buckle 1313 and the second elastic buckle 1314 can be used to prevent the dust collection box 34 from vibrating and loosening, so that the dust collection box 34 can maintain a stable position during the operation of the air conditioner, the cleaning of the filter screen 2, or the dust collection process of the vacuum cleaner 6.

[0066] The dust collection box 34 can be provided with a corresponding groove to cooperate with the first elastic buckle 1313 / second elastic buckle 1314 to further improve the positional reliability. Alternatively, the dust collection box 34 can be provided without a groove, and can directly abut against the first elastic buckle 1313 / second elastic buckle 1314 using its smooth outer wall surface.

[0067] In some exemplary embodiments, the dust collection box 34 is provided with a handle position 3413, such as Figure 10 As shown, the handle 3413 allows the user to hold the dust collection box 34, making it easy for the user to remove the dust collection box 34, reducing the difficulty of disassembling the dust collection box 34 and improving the user experience.

[0068] The specific structural form of the handle position 3413 is not limited, and it can be, but is not limited to, at least one of the following: a protruding handle, a concave handle groove, etc.

[0069] In some exemplary embodiments, such as Figure 9 As shown, the mounting cavity 1311 has an open end (i.e., front end) facing the air conditioner panel 5. The dust collection box 34 includes a box body 341 and a box cover 342 connected to the box body 341. A vacuum cleaner interface 3411 is provided at the end of the box body 341 facing the panel 5, such as... Figure 12 As shown. The cover 342 is located at the vacuum cleaner interface 3411 and is configured to open or close the vacuum cleaner interface 3411, as shown. Figure 11 and Figure 12 As shown.

[0070] In this way, the user can connect the vacuum cleaner 6 to the dust collection box 34, such as... Figure 12 As shown, the dust in the dust collection box 34 is sucked out by the vacuum cleaner 6 without disassembling the dust collection box 34 for emptying.

[0071] In some exemplary embodiments, the bottom of the vacuum cleaner interface 3411 is provided with a baffle 3412, such as... Figures 10 to 12 As shown. The top of the lid 342 is rotatably connected to the box body 341, and the bottom of the lid 342 is stopped by the baffle 3412. The lid 342 is configured to be able to rotate inward and open under external force.

[0072] In this way, when using the vacuum cleaner 6, the user can simply press the vacuum cleaner 6 against the lid 342 to open the lid 342 and insert it into the container 341 to perform vacuuming. When vacuuming is complete, simply pull the vacuum cleaner 6 out, and the lid 342 will automatically fall down under gravity, closing the vacuum cleaner interface 3411. The entire operation requires no separate operation of the lid 342 by the user, making it highly convenient. Furthermore, the baffle 3412 helps to limit the lid 342 from rotating outwards and causing dust to leak out.

[0073] In some exemplary embodiments, the cleaning assembly 3 further includes a resilient reset member 343, such as Figure 11 and Figure 12 As shown, the elastic reset member 343 cooperates with the cover 342 and is configured to use its reset elasticity to drive the cover 342 back to the position where the vacuum cleaner interface 3411 is closed. This allows the cover 342 to remain stably in the closed position, improving the sealing of the dust collection box 34 and helping to prevent the cover 342 from being accidentally opened and causing dust to leak out.

[0074] The elastic reset component 343 can be, but is not limited to, a torsion spring, leaf spring, tension spring, compression spring, etc.

[0075] For example, the lid 342 is rotatably connected to the box body 341 via a pivot 3421. A torsion spring is sleeved on the pivot 3421. One torsion arm of the torsion spring abuts against the inner wall of the box body 341, and the other torsion arm abuts against the lid 342.

[0076] like Figures 1 to 6 As shown in the illustration, this application also provides an air conditioner, including: a housing and a filter device 100 as described in any of the above embodiments, which is installed in the housing and detachably connected to the housing via a detachable connection portion. The air conditioner may also include structures such as a heat exchanger 7 and a chassis assembly 8.

[0077] The air conditioner provided in this application embodiment has all the above-mentioned beneficial effects because it includes the filter device 100 of any of the above embodiments, and will not be repeated here.

[0078] The type of air conditioner is not limited; it can be the indoor unit of a split air conditioner (such as a wall-mounted indoor unit, a ceiling-mounted indoor unit, or a cabinet-type indoor unit), or a complete split air conditioner including both an indoor and outdoor unit, or an integrated air conditioner.

[0079] In one embodiment, such as Figures 1 to 7 As shown, the air conditioner is a wall-mounted indoor unit. The filter device 100 is arranged in an L-shape and installed on the top and left side of the wall-mounted indoor unit. The top of the filter device 100 is located at the air inlet on the top of the casing. The left side of the filter device 100 is obscured by the panel 5.

[0080] In some exemplary embodiments, such as Figures 1 to 6 As shown, the housing includes a face frame 4 and a panel 5 rotatably connected to the face frame 4. The filter device 100 is mounted on the face frame 4 and detachably connected to the face frame 4 via a detachable connection.

[0081] Panel 5 can rotate relative to faceplate 4 between an open position and a closed position. This is based on panel 5 being in the closed position (e.g., ...). Figure 1As shown), panel 5 blocks the portion of filter device 100 facing panel 5 to ensure the integrity of the air conditioner's appearance. This is based on panel 5 being in the open position (e.g., Figure 2 As shown, the filter device 100 can be detached from the faceplate 4. Therefore, when it is necessary to detach the filter device 100, simply open the faceplate 5 to see the filter device 100, and then detach or assemble the filter device 100.

[0082] In one embodiment, the front end of the faceplate 4 is provided with a clearance notch for the filter device 100 to enter and exit. The clearance notch includes a first notch 431 for the top of the filter device 100 to enter and exit, and a second notch 432 for the left side of the filter device 100 to enter and exit. Figure 6 As shown. The detachable connection includes a snap fastener 14 and a fixing hole 15.

[0083] During installation, first push the filter device 100 into the face frame 4 through the clearance notch, so that the buckle 14 is inserted into the insertion hole 41 at the rear end of the face frame 4. At this time, the fixing hole 15 of the filter device 100 is aligned with the connecting hole 42 at the front end of the face frame 4. Then tighten the screws. At this time, the front end of the dust collection box 34 is located at the first notch 431. The user can disassemble and assemble the dust collection box 34 through the first notch 431, or insert the vacuum cleaner 6 through the first notch 431 for vacuuming. After that, rotate the panel 5 to the closed position.

[0084] When maintenance, repair, or replacement of the filter device 100 is required, rotate the panel 5 to the open position, remove the fasteners at the fixing holes 15, and then pull the filter device 100 forward. This method can be applied when there is no interference between the panel 5 and the filter device 100, such as when the connection between the panel 5 and the frame 4 is completely located on the left and right sides of the filter device 100, and the filter device 100 will not interfere with the panel 5 when moving back and forth relative to the frame 4. However, when the connection between the panel 5 and the frame 4 is not completely located on the left and right sides of the filter device 100, the panel 5 can be removed first, and then the filter device 100 can be disassembled and assembled.

[0085] In other embodiments, the filter device 100 can also be installed by upward disassembly and downward installation. For example, during installation, the filter device 100 is first pushed into the face frame 4 at an angle through the return air vent, so that the buckle 14 is inserted into the insertion hole 41 at the rear end of the face frame 4. Then, the filter device 100 is laid flat, at which point the fixing hole 15 of the filter device 100 is aligned with the connecting hole 42 at the front end of the face frame 4. Then, the screws are tightened. At this time, the front end of the dust collection box 34 is located at the first notch 431. The user can disassemble and assemble the dust collection box 34 through the first notch 431, or insert a vacuum cleaner 6 through the first notch 431 for vacuuming. Then, the panel 5 is rotated to the closed position. When it is necessary to perform maintenance, repair, or replacement of the filter device 100, the panel 5 is rotated to the open position, then the fasteners at the fixing hole 15 are removed, the panel 5 is replaced, and then the filter device 100 is tilted appropriately so that the buckle 14 is dislodged from the insertion hole 41. Then, the filter device 100 is pulled upward. Of course, when the filter device 100 is disassembled and installed in this way, the panel 5 can also be removed in advance to reduce the difficulty of disassembling and installing the filter device 100 later.

[0086] In some exemplary embodiments, the air conditioner also includes a control device electrically connected to the cleaning assembly 3 and configured to control the cleaning assembly 3. The control device may store an automatic cleaning program, enabling periodic automatic cleaning and user-initiated cleaning of the filter 2 as needed, thereby achieving automatic dust removal from the air intake filter 2, preventing clogging and bacterial growth, and improving the air conditioner's performance.
