[0008] A first sealing ring is located along the axial direction of the filter assembly at one end of the filter assembly facing the air outlet, and the first sealing ring has a first sealing rib extending circumferentially along the first sealing ring; and

[0009] The second sealing ring contacts the first sealing ring radially along the filter assembly, and the second sealing ring is interference-fitted with the first sealing rib.

[0010] One of the first sealing ring and the second sealing ring is connected to the filter assembly, and the other of the first sealing ring and the second sealing ring is connected to the mounting bracket.

[0011] In one embodiment, the first sealing ring is a rigid component, and the second sealing ring is an elastic component.

[0012] In one embodiment, the first sealing ring is integrally formed with the filter assembly, or the first sealing ring is detachably connected to the filter assembly.

[0013] In one embodiment, the first sealing rib is annular.

[0014] In one embodiment, the filter device has a second sealing rib, which is located between the first sealing ring and the second sealing ring along the axial direction of the filter assembly, and is located outside the first sealing rib along the radial direction of the filter assembly; the second sealing rib is spaced from the first sealing ring by a first preset distance, and / or the second sealing rib is spaced from the second sealing ring by a second preset distance.

[0015] In one embodiment, the second sealing rib is annular.

[0016] In one embodiment, the filter assembly includes:

[0017] Connecting base, which is driven to connect with the driving component; and

[0018] A first filter screen surrounds the connecting seat, forming the air outlet. The first filter screen and the connecting seat together form a flow channel communicating with the air outlet, and the air outlet is located at one end of the flow channel axially away from the connecting seat.

[0019] In one embodiment, the connector has a mounting cavity located on the side of the connector opposite to the flow channel, the mounting cavity being recessed toward the air outlet, and the drive member being located within the mounting cavity.

[0020] In one embodiment, the mounting bracket includes:

[0021] The front bracket is located at one end of the filter assembly axially opposite to the air outlet; and

[0022] A rear bracket is connected to the front bracket. The rear bracket is located at one end of the filter assembly facing the air outlet along the axial direction. The rear bracket and the front bracket form the air intake channel. The first sealing ring and the second sealing ring are both located between the rear bracket and the filter assembly. The first sealing ring and the second sealing ring are selectively connected to the rear bracket.

[0023] In one embodiment, the drive element is mounted on the front bracket.

[0024] In one embodiment, the rear support includes:

[0025] A bracket body is located at one end of the filter assembly facing the air outlet along the axial direction. The bracket body and the front bracket form the air intake channel. Both the first sealing ring and the second sealing ring are located between the bracket body and the filter assembly. One of the first sealing ring and the second sealing ring is selectively connected to the bracket body. The bracket body forms an exhaust channel communicating with the air outlet.

[0026] The second filter is connected to the bracket body and is located inside the exhaust channel.

[0033] In the filtering device of this application embodiment, since the second sealing ring and the first sealing rib form an interference fit in radial contact, axial installation position deviation of the filter assembly will not affect the radial contact and sealing between the second sealing ring and the first sealing rib. This ensures a good sealing effect between the first sealing rib and the second sealing ring, and prevents excessive axial compression between the filter assembly and the mounting bracket due to axial installation position deviation, thus avoiding interference with the rotation of the filter assembly. The radial contact and interference fit between the second sealing ring and the first sealing rib eliminates the need to consider end-face sealing of the first and second sealing rings along the axial direction of the filter assembly, thereby alleviating to some extent the problem of difficult control of dimensional tolerances of the first and second sealing rings along the axial direction of the filter assembly.

Detailed Implementation

[0057] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0058] In the description of the embodiments in this application, "upper," "lower," "top," "bottom," orientation, or positional relationship are based on the appendix. Figure 1 The orientations or positional relationships shown are for illustrative purposes only and do not imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Figure 1 For reference, the direction indicated by arrow R1 in the diagram is the up and down direction.

[0059] In the description of the embodiments of this application, Figure 2 For reference, the direction indicated by arrow R2 in the diagram is the front-to-back direction.

[0060] In the description of the embodiments of this application, please refer to Figure 11 , Figure 14 as well as Figure 17 The driving component 3 drives the filter assembly 2 to rotate around the rotation axis CL. The inner and outer directions refer to the direction along the radial direction of the filter assembly 2 pointing towards the rotation axis CL as inner, and the direction along the radial direction of the filter assembly 2 away from the rotation axis CL as outer.

[0061] As part of the inventive concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons why it is difficult to simultaneously achieve the rotation of the filter assembly and the sealing effect of the filter device in the related art, and obtain the technical solution of the embodiments of this application through reasonable analysis.

[0062] For related technologies, please refer to Figure 21 and Figure 22 The filtration device 83 of the garment processing system includes a mounting bracket 1, a first sealing ring 4, a second sealing ring 5, and a filter assembly 2 located within the mounting bracket 1. At the air outlet 21 of the filter assembly 2, the filter assembly 2 of the filtration device 83 is sealed to the mounting bracket 1 by the end faces of the first sealing ring 4 and the second sealing ring 5 arranged along the axial direction of the filter assembly 2. The first sealing ring 4 is connected to the filter assembly 2, and the second sealing ring 5 is connected to the mounting bracket 1. The sealing effect between the first sealing ring 4 and the second sealing ring 5 is greatly affected by the tightness between the filter assembly 2 and the mounting bracket 1. The filter assembly 2 may need to be removed from the mounting bracket 1 for replacement and maintenance. During the disassembly and assembly process, the tightness between the filter assembly 2 and the mounting bracket 1 is greatly affected by the human factors of the operator. There may be a certain deviation in the axial installation position of the filter assembly 2. The dimensional tolerance of the first sealing ring 4 and the second sealing ring 5 along the axial direction of the filter assembly 2 is difficult to control. It is difficult to grasp the tightness between the filter assembly 2 and the mounting bracket 1 just right. There may be cases where the filter assembly 2 is too loose or too tight. If the filter assembly 2 and the mounting bracket 1 are installed too tightly, the first sealing ring 4 and the second sealing ring 5, which are arranged axially along the filter assembly 2, will be subjected to greater compressive force, which is beneficial for sealing. However, the friction between the end faces of the first sealing ring 4 and the second sealing ring 5 along the axial direction of the filter assembly 2 will be greater, which may make it difficult for the filter assembly 2 to rotate. If the filter assembly 2 and the mounting bracket 1 are installed too loosely, a gap will form between the first sealing ring 4 and the second sealing ring 5. The friction between the end faces of the two sealing rings along the axial direction of the filter assembly 2 will be less or even almost non-existent, which is beneficial for the rotation of the filter assembly 2. However, due to the gap between the two sealing rings, the sealing effect will be poor, and unfiltered airflow may flow in through the gap between the first sealing ring 4 and the second sealing ring 5, resulting in a higher content of lint and other dust in the subsequent airflow.

[0063] Therefore, this application provides a garment processing system. Please refer to the embodiments provided. Figures 1 to 8 The garment handling system includes a housing assembly 81, a garment handling drum 82, and a filter device 83. The garment handling drum 82 is mounted on the housing assembly 81. The filter device 83 is mounted on the housing assembly 81, and the airflow for handling garments circulates between the garment handling drum 82 and the filter device 83. With this structure, lint and other debris carried by the airflow exiting the garment handling drum 82 are filtered out as it passes through the filter device 83. The airflow after filtration by the filter device 83 carries less lint and other debris, thus having less impact on subsequent components through which the airflow passes.

[0064] In one embodiment, the clothing handling system can be a dryer.

[0065] For the filtering device 83 of this application embodiment, please refer to [link / reference]. Figure 9 , Figure 12 as well as Figure 15The filter device 83 includes a mounting bracket 1, a filter assembly 2, a drive member 3, a first sealing ring 4, and a second sealing ring 5. The mounting bracket 1 forms an air inlet channel 11. The filter assembly 2 is used to filter airflow. The filter assembly 2 is located within the mounting bracket 1, communicates with the air inlet channel 11, and has an air outlet 21. The drive member 3 is driven to rotate the filter assembly 2. The first sealing ring 4 is located along the axial direction of the filter assembly 2 at one end facing the air outlet 21, and has a first sealing rib 41 extending circumferentially along its length. The second sealing ring 5 contacts the first sealing ring 4 radially along the filter assembly 2, and is press-fitted with the first sealing rib 41. One of the first sealing ring 4 and the second sealing ring 5 is connected to the filter assembly 2, and the other is connected to the mounting bracket 1. In this structure, one of the first sealing ring 4 and the second sealing ring 5 is connected to the filter assembly 2, and the other of the first sealing ring 4 and the second sealing ring 5 is connected to the mounting bracket 1. The driving component 3 drives the filter assembly 2 to rotate, so that the first sealing ring 4 and the second sealing ring 5 will rotate relative to each other. The second sealing ring 5 is interference-fitted with the first sealing rib 41 of the first sealing ring 4, so that the first sealing rib 41 and the second sealing ring 5 can be well sealed. The second sealing ring 5 and the first sealing rib 41 are interference-fitted, causing the first sealing rib 41 and the second sealing ring 5 to press against each other and generate a certain frictional force during mutual rotation. This frictional force is mainly determined by the interference amount between the second sealing ring 5 and the first sealing rib 41, which is determined by the radial dimensions of the second sealing ring 5 and the first sealing rib 41. The axial installation position of the filter assembly 2 has almost no effect on the interference amount between the second sealing ring 5 and the first sealing rib 41, and will not affect the sealing effect between the second sealing ring 5 and the first sealing rib 41. During the installation of the filter assembly 2, even if the axial installation position of the filter assembly 2 changes slightly, the frictional force between the first sealing rib 41 and the second sealing ring 5 in radial contact along the filter assembly 2 will hardly change. The first sealing rib 41 and the second sealing ring 5 are press-fitted together to form a seal. This effectively alleviates the problem of the filter assembly 2 being too tightly installed between the filter assembly 2 and the mounting bracket 1, resulting in high friction between the first sealing ring 4 and the second sealing ring 5, and difficulty in rotating the filter assembly 2, caused by slight changes in the axial installation position of the filter assembly 2 or deviations in the axial installation position. Since the second sealing ring 5 and the first sealing rib 41 are press-fitted together to form a seal, it is not necessary for the end faces of the first sealing ring 4 and the second sealing ring 5 to adhere to each other along the axial direction of the filter assembly 2 for sealing. Therefore, the dimensional tolerances of the first sealing ring 4 and the second sealing ring 5 along the axial direction of the filter assembly 2 do not need to be considered in terms of sealing, reducing the difficulty of tolerance control.

[0066] It should be explained that the driving component 3 drives the filter assembly 2 to rotate around the rotation axis CL, and the axial direction of the filter assembly 2 refers to the extension direction of the rotation axis CL.

[0067] It should be explained that the driving component 3 drives the filter assembly 2 to rotate around the rotation axis CL, and the radial direction of the filter assembly 2 refers to the direction perpendicular to the rotation axis CL.

[0068] It should be explained that the interference fit between the second sealing ring 5 and the first sealing rib 41 is not merely a tight contact, but rather there is a certain amount of interference between them, resulting in mutual compression. The interference fit referred to in this application embodiment includes not only the interference fit typically defined by tolerances in the mechanical field, but also the interference caused by the basic size of the outer diameter of the first sealing rib 41 being larger than the basic size of the inner diameter of the second sealing ring 5.

[0069] For example, the basic outer diameter of the first sealing rib 41 is 15mm, the basic inner diameter of the second sealing ring 5 is 13mm, the second sealing ring 5 is located outside the first sealing rib 41, and the basic inner diameter of the second sealing ring 5 is smaller than the basic outer diameter of the first sealing rib 41. When the second sealing ring 5 is fitted onto the first sealing rib 41, a compression is formed between the first sealing ring 41 and the first sealing rib 41, and the interference between the second sealing ring 5 and the first sealing rib 41 is approximately 1mm.

[0070] In one embodiment, please refer to Figure 19 The first sealing rib 41 is annular. In this way, a better seal can be formed.

[0071] In one embodiment, the first sealing ring 4 and the second sealing ring 5 can be made of materials with a low coefficient of friction. For example, the first sealing ring 4 can be made of Teflon or nylon, and / or the second sealing ring 5 can be made of Teflon or nylon.

[0072] In one embodiment, please refer to Figure 12 and Figure 15 The first sealing ring 4 and the second sealing ring 5 are spaced a third preset distance D2 along the axial direction of the filter assembly 2. This structural design facilitates smoother rotation of the filter assembly 2 by the drive component 3.

[0073] In one embodiment, please refer to Figure 12 , Figure 15 , Figure 18 as well as Figure 19The filter device 83 has a second sealing rib 6, which is located axially between the first sealing ring 4 and the second sealing ring 5 of the filter assembly 2, and radially outside the first sealing rib 41 of the filter assembly 2. With this structure, the second sealing rib 6, located outside the first sealing rib 41, can, to a certain extent, block lint and other debris in the airflow passing between the first sealing ring 4 and the second sealing ring 5 towards the first sealing rib 41, thereby improving the overall sealing effect of the filter device 83.

[0074] In one embodiment, the second sealing rib 6 is spaced apart from the first sealing ring 4 by a first preset distance. With this structure, there is almost no friction between the second sealing rib 6 and the first sealing ring 4, which facilitates smoother rotation of the filter assembly 2.

[0075] In one embodiment, when the second sealing rib 6 is spaced apart from the first sealing ring 4 by a first preset distance, the second sealing rib 6 can be integrally formed with the second sealing ring 5.

[0076] In one embodiment, please refer to Figure 12 and Figure 15 The second sealing rib 6 and the second sealing ring 5 are spaced apart by a second preset distance D1.

[0077] In one embodiment, please refer to Figure 12 and Figure 15 When the second sealing rib 6 and the second sealing ring 5 are spaced apart by a second preset distance D1, the second sealing rib 6 can be integrally formed with the first sealing ring 4. With this structure, there is almost no friction between the second sealing rib 6 and the second sealing ring 5, which is conducive to the smoother rotation of the filter assembly 2.

[0078] In one embodiment, the second sealing rib 6 is spaced apart from the first sealing ring 4 by a first preset distance, and the second sealing rib 6 is spaced apart from the second sealing ring 5 by a second preset distance D1. The second sealing rib 6 can be supported on the mounting bracket 1.

[0079] In one embodiment, please refer to Figure 19 The second sealing rib 6 is ring-shaped. In this way, it can effectively block lint and other debris.

[0080] In one embodiment, the first sealing ring 4 is a rigid component, and the second sealing ring 5 is an elastic component. With this structure, when the first sealing rib 41 and the second sealing ring 5 are pressurized together by an interference fit, the second sealing ring 5 will be concave away from the first sealing rib 41 at the contact point due to the pressure from the first sealing rib 41. The first sealing rib 41 will be partially pressed into the space formed by the concavity of the second sealing ring 5. Even if fluid carrying lint or other debris flows between the first sealing rib 41 and the second sealing ring 5, the path of the fluid carrying lint or other debris will be tortuous, increasing the flow resistance and improving the sealing performance between the second sealing ring 5 and the first sealing rib 41.

[0081] It should be explained that rigid and elastic components are relative terms. When two objects are pressed and in contact, the object that deforms more at the contact point is an elastic component, while the object that deforms less at the contact point is a rigid component.

[0082] In one embodiment, the first sealing ring 4 can be a rigid component made of a relatively hard material such as plastic or metal.

[0083] In one embodiment, the second sealing ring 5 can be an elastic element made of a softer material such as rubber or silicone.

[0084] In one embodiment, the first sealing ring 4 may be configured as an elastic element or a rigid element, depending on the circumstances.

[0085] In one embodiment, please refer to Figure 9 ,as well as Figures 13-19 The first sealing ring 4 can be integrally formed with the filter assembly 2. With this structural form, the first sealing ring 4 and the filter assembly 2 can be made into a single component, reducing the number of parts and simplifying the overall structure, which can reduce the failure rate to a certain extent.

[0086] It is understandable that the first sealing rib 41 of the first sealing ring 4 contacts and rubs against the second sealing ring 5, making the first sealing ring 4 more prone to wear and requiring maintenance. In one embodiment, please refer to... Figures 9-12 The first sealing ring 4 is detachably connected to the filter assembly 2. With this structure, when the first sealing ring 4 needs to be replaced or repaired, it can be removed from the filter assembly 2, repaired or replaced, and then reinstalled onto the filter assembly 2. It is not necessary to replace the entire filter assembly 2, which is beneficial for equipment maintenance.

[0087] In one embodiment, the detachable connection can be a bolted connection, a screw connection, or a snap-fit ​​connection, etc.

[0088] In one embodiment, the first sealing ring 4 may be riveted or welded to the filter assembly 2.

[0089] It is understandable that in connection methods such as welding, riveting, or detachable connections, the first sealing ring 4 and the filter assembly 2 are two different components connected together. The material of the first sealing ring 4 can be different from that of the filter assembly 2, and the material of the first sealing ring 4 can be selected according to actual needs. For example, the first sealing ring 4 can be made of a material with a low coefficient of friction, while the material of the filter assembly 2 does not have requirements regarding the coefficient of friction.

[0090] In one embodiment, the first sealing ring 4 is integrally formed with the filter assembly 2, and the second sealing ring 5 is connected to the mounting bracket 1. The first sealing ring 4 is either detachably or non-detachably connected to the filter assembly 2, and the second sealing ring 5 is connected to the mounting bracket 1.

[0091] In one embodiment, the first sealing ring 4 can be connected to the mounting bracket 1, and the second sealing ring 5 can be connected to the filter assembly 2, depending on the situation.

[0092] In one embodiment, please refer to Figures 9-15 The second sealing ring 5 is located radially outside the first sealing rib 41 of the filter assembly 2. With this structure, the second sealing ring 5 will not obstruct the air outlet 21 of the filter assembly 2, which is conducive to the airflow passing through the filter assembly 2 being discharged from the air outlet 21 of the filter assembly 2.

[0093] In one embodiment, the second sealing ring 5 may be located radially inside the first sealing rib 41 of the filter assembly 2.

[0094] In one embodiment, please refer to Figures 16-19 The filter assembly 2 includes a connecting seat 22 and a first filter 23. The connecting seat 22 is drivenly connected to the driving component 3. The first filter 23 surrounds the connecting seat 22, forming an air outlet 21. The first filter 23 and the connecting seat 22 form a flow channel 24 communicating with the air outlet 21. The air outlet 21 is located at one end of the flow channel 24 axially away from the connecting seat 22. With this structure, the airflow reaching the filter assembly 2 through the air inlet channel 11 is filtered by the first filter 23, enters the flow channel 24, and flows out from the air outlet 21. The connecting seat 22 is located at the end of the flow passage 24 away from the air outlet 21 and serves to block it. On the one hand, it prevents the filtered airflow in the flow passage 24 from flowing out from the end of the flow passage 24 away from the air outlet 21 and mixing with the unfiltered airflow, thus contaminating the filtered airflow. On the other hand, it prevents the airflow that has not been filtered by the first filter screen 23 from entering the flow passage 24 from the end of the flow passage 24 away from the air outlet 21 and contaminating the filtered airflow in the flow passage 24.

[0095] It should be explained that the driving component 3 drives the connecting seat 22 to rotate around the rotation axis CL, and the end of the flow channel 24 that is axially away from the connecting seat 22 refers to the end of the flow channel 24 that is away from the connecting seat 22 along the extension direction of the rotation axis CL.

[0096] In one embodiment, please refer to Figure 9 ,as well as Figures 13-19 The first sealing ring 4 can be integrally formed with the first filter screen 23.

[0097] In one embodiment, please refer to Figures 16-19 The connecting seat 22 has a mounting cavity 221 located on the side of the connecting seat 22 opposite to the flow channel 24. The mounting cavity 221 is recessed towards the air outlet 21, and the drive member 3 is located inside the mounting cavity 221. This structural configuration, with the mounting cavity 221 recessed towards the air outlet 21, fully utilizes the space inside the first filter 23 to arrange the connecting seat 22 and the drive member 3 within the mounting cavity 221, saving space. The drive member 3 being located within the mounting cavity 221 conceals it within the connecting seat 22, reducing the exposure of the drive member 3 and lowering the risk of the drive shaft of the drive member 3 becoming entangled in lint carried by the airflow.

[0098] In one embodiment, the driving element 3 can be a motor.

[0099] In one embodiment, please refer to Figures 9-15 The mounting bracket 1 includes a front bracket 12 and a rear bracket 13. The front bracket 12 is located at the end of the filter assembly 2 facing away from the air outlet 21 along the axial direction. The rear bracket 13 is connected to the front bracket 12. The rear bracket 13 is located at the end of the filter assembly 2 facing the air outlet 21 along the axial direction. The rear bracket 13 and the front bracket 12 form an air intake channel 11. The first sealing ring 4 and the second sealing ring 5 are both located between the rear bracket 13 and the filter assembly 2, and one of the first sealing ring 4 and the second sealing ring 5 is selectively connected to the rear bracket 13. With this structure, the filter assembly 2 is installed between the front bracket 12 and the rear bracket 13, and receives airflow carrying lint and other debris through the air intake channel 11 formed by the front bracket 12 and the rear bracket 13. The airflow carrying lint and other debris flows to the filter assembly 2 through the air intake channel 11. When maintenance of the filter assembly 2 is required, the front bracket 12 and the rear bracket 13 can be disassembled, allowing the filter assembly 2 to be easily removed for maintenance, making the maintenance operation relatively convenient.

[0100] It should be explained that the filter assembly 2 is axially away from the end of the air outlet 21, and the filter assembly 2 is axially towards the end of the air outlet 21. Here, the axial direction refers to the extension direction of the rotation axis CL.

[0101] In one embodiment, the front bracket 12 and the rear bracket 13 are detachably connected.

[0102] In one embodiment, please refer to Figures 9-15The drive component 3 is mounted on the front bracket 12. With this structure, on the one hand, the front bracket 12 can provide relatively stable support for the drive component 3. On the other hand, the drive component 3 being mounted on the front bracket 12 will not obstruct the air outlet 21 of the filter assembly 2, which can conveniently drive the filter assembly 2 to rotate without affecting the air outlet 21 of the filter assembly 2.

[0103] In one embodiment, the filter device 83 further includes a motor mounting plate connected to the front bracket 12. The drive component 3 is mounted on the motor mounting plate.

[0104] In one embodiment, please refer to Figure 20 The rear support 13 includes a support body 131 and a second filter 132. The support body 131 is located at the end of the filter assembly 2 facing the air outlet 21 along the axial direction. The support body 131 and the front support 12 form an air intake channel 11. The first sealing ring 4 and the second sealing ring 5 are both located between the support body 131 and the filter assembly 2. The first sealing ring 4 and the second sealing ring 5 are selectively connected to the support body 131. The support body 131 forms an exhaust channel 1311 that communicates with the air outlet 21. The second filter 132 is connected to the support body 131 and is located within the exhaust channel 1311. With this structure, the gas filtered by the filter assembly 2 and flowing out of the air outlet 21 of the filter assembly 2 will flow through the exhaust channel 1311 and undergo a second filtration through the second filter 132 within the exhaust channel 1311, thereby reducing the content of impurities such as lint carried in the airflow.

[0105] In one embodiment, please refer to Figure 10 , Figure 13 as well as Figure 20 The air intake channel 11 is located above the filter assembly 2, and / or the air intake channel 11 is located on at least one side of the filter assembly 2 along the target direction, which is respectively intersected with the vertical direction and the rotation axis CL.

[0106] In one embodiment, the target direction is perpendicular to the vertical direction and the rotation axis CL.

[0107] In one embodiment, please refer to Figure 10 as well as Figure 13 The target direction is as shown by arrow R3 in the figure.

[0108] In one embodiment, please refer to Figure 10 as well as Figure 13 The front bracket 12 and the rear bracket 13 also form a sewage discharge channel 14, which is located below the filter assembly 2. This facilitates the discharge of wastewater generated during the cleaning of the filter assembly 2 through the sewage discharge channel 14.

[0109] In one embodiment, please refer to Figure 5 as well as Figure 8The housing assembly 81 has a flow guide surface 811 and a water storage tank 812. The flow guide surface 811 is located below the filter device 83 to guide the wastewater generated during cleaning of the filter device 83 to the water storage tank 812.

[0110] In one embodiment, please refer to Figure 5 The guide surface 811 is located below the filter assembly 2 to guide the wastewater generated from cleaning the filter assembly 2 to the water storage tank 812.

[0111] In one embodiment, the sewage discharged from the sewage channel 14 flows into the guide surface 811.

[0112] In one embodiment, please refer to Figures 1-5 Along the direction from the filter device 83 to the water storage tank 812, the guide surface 811 gradually slopes downwards. The filter device 83 and the water storage tank 812 are located at the same end of the clothing processing drum 82. This structural configuration results in a closer distance between the filter device 83 and the water storage tank 812. For the same height difference, this increases the angle between the guide surface 811 and the horizontal direction, facilitating the smooth flow of wastewater and debris such as lint carried in the wastewater on the guide surface 811. This prevents the accumulation of lint and other debris on the guide surface 811.

[0113] It should be explained that the gradual downward tilt of the guide surface 811 indicates that the height of the guide surface 811 gradually decreases.

[0114] In one embodiment, please refer to Figures 1-5 The water storage tank 812 and the filter device 83 are located at the front end of the clothing processing drum 82.

[0115] In one embodiment, please refer to Figures 1 to 8 The garment handling system also includes a wastewater discharge component 85, which is used to discharge wastewater from the water storage tank 812.

[0116] In one embodiment, please refer to Figure 6 and Figure 8 The garment processing system also includes a water supply component 86, which supplies water to the filter device 83 for cleaning the filter device 83.

[0117] In one embodiment, the water supply component 86 is connected to an external water source, and the external water source flows through the water supply component 86 to the filter device 83 to clean the filter device 83.

[0118] In one embodiment, when the water supply component 86 is connected to an external water source, the water supply component 86 can be an inlet valve.

[0119] In one embodiment, the water supply component 86 can deliver condensate to the filter device 83 to clean the filter device 83.

[0120] In one embodiment, when the water supply component 86 is used to transport condensate, the water supply component 86 can be a water supply pump.

[0121] In one embodiment, please refer to Figure 2 The garment processing system also includes a heat exchanger 84 installed on the housing assembly 81. The airflow for processing the garments circulates sequentially between the garment processing cylinder 82, the filter device 83, and the heat exchanger 84. In this configuration, the airflow from the garment processing cylinder 82 is filtered by the filter device 83, and the cleaner airflow passes through the heat exchanger 84 to form a hot airflow that flows back to the garment processing cylinder 82 to dry the garments.

[0122] In one embodiment, the water supply component 86 delivers the condensate discharged from the heat exchanger 84 to the filter device 83 to clean the filter device 83.

[0123] In one embodiment, the heat exchanger 84 includes an evaporator 841 and a condenser 842. The airflow for processing clothes circulates sequentially between the clothes processing drum 82, the filter device 83, the evaporator 841, and the condenser 842. The clean airflow filtered by the filter device 83 flows to the evaporator 841 and then enters the condenser 842 to form a hot airflow. The hot airflow flows to the clothes processing drum 82 to dry the clothes.

[0124] In one embodiment, the water supply component 86 delivers the condensate discharged from the evaporator 841 to the filter device 83 to clean the filter device 83.

[0125] In one embodiment, the condensate discharged from the heat exchanger 84 can flow to the water storage tank 812.

[0126] Once the operation is successful, the condensate produced by the evaporator 841 can flow to the water storage tank 812.

[0127] Understandably, because the filter assembly 2 and the mounting bracket 1 have good sealing performance and the filter assembly 2 can rotate relatively smoothly, the airflow flowing through the air intake channel 11 is basically filtered by the filter assembly 2 before flowing to the heat exchanger 84, which can effectively prevent lint and other debris in the airflow from clogging the heat exchanger 84.

[0128] In one embodiment, it is possible to prevent debris such as lint in the airflow from clogging the evaporator 841.

[0129] In one embodiment, please refer to Figure 7 and Figure 8The housing assembly 81 has an operation window 813, and the filter device 83 is located inside the operation window 813 and connected to the housing assembly 81. The heat exchanger 84 is located at one end of the operation window 813. This structure allows for easy assembly and disassembly of the filter device 83 as a modular unit within the operation window 813, facilitating its maintenance. Furthermore, the location of the heat exchanger 84 at one end of the operation window 813 allows for convenient cleaning and maintenance of the heat exchanger 84 by removing the filter device 83 and accessing it through the operation window 813 when lint or other blockages occur.
