A filtration device and a garment processing equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on and claims priority to Chinese Patent Application No. 202410515316.8, filed on April 26, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clothing processing equipment technology, and more particularly to a filtration device and clothing processing equipment. Background Technology

[0004] Taking the filtration device of a garment processing equipment as an example, during use, impurities such as lint remain inside the filtration device. Related technologies utilize flexible scrapers to clean the filter screen. This approach requires a rigid support on one side of the flexible scraper to prevent excessive deformation and allow for the application of appropriate elastic force to the filter screen. However, this structure requires a special rigid support to support the flexible scraper, and the contact area between the flexible scraper and the end of the rigid support is prone to shearing force and cracking. To improve shearing force, the end of the rigid support needs to be designed as spherical, which increases the structural requirements of the rigid support and also increases the dimension perpendicular to the thickness direction of the flexible scraper.

[0005] Summary of the Invention

[0006] In view of this, embodiments of this application aim to provide a filtration device and a garment processing equipment to ensure the cleaning ability of the flexible scraper while reducing the structural requirements of the rigid support.

[0007] To achieve the above objectives, a first aspect of the embodiments of this application provides a filtration device, comprising:

[0022] In some embodiments, at least one of the damping protrusions and the protrusions are spaced apart on the surface of the scraper body, and the degree of protrusion of the protrusions on the surface of the scraper body is greater than the degree of protrusion of the protrusions; and / or, at least one of the damping protrusions is disposed at the end of the protrusions away from the scraper body.

[0049] Referring to Figures 1, 2 and 3, a first aspect of the present application provides a filtering device 10, including: a housing 101, a first filtering component 102 and a cleaning component 103.

[0050] The filter device 10 can filter impurities in the passing airflow according to the usage scenario.

[0051] Referring to Figures 2 and 3, the housing 101 has an air inlet 101b and an air outlet 101c. Specifically, the interior of the housing 101 has a receiving space 101a, which connects the air inlet 101b and the air outlet 101c. It can be understood that airflow from outside the housing 101 flows into the receiving space 101a through the air inlet 101b and then flows out through the air outlet 101c.

[0052] The first filter assembly 102 is disposed on the housing 101 and is used to filter the airflow flowing through the housing 101. It is understood that the airflow flowing through the housing 101 can pass through the first filter assembly 102, and the first filter assembly 102 can intercept impurities in the airflow, so as to reduce the impurity content in the airflow flowing out of the housing 101.

[0053] Referring to Figures 4 and 5, the cleaning assembly 103 is at least partially disposed inside the housing 101. The cleaning assembly 103 includes a frame structure 1032 and a flexible scraper 1031, the flexible scraper 1031 being connected to one end of the frame structure 1032 along a first direction. This makes the cleaning assembly 103 have a compact structure.

[0054] The skeleton structure 1032 is used to drive the flexible scraper 1031 to move, so that the flexible scraper 1031 contacts the first filter assembly 102 during movement and cleans the first filter assembly 102. It can be understood that after impurities in the airflow flowing through the first filter assembly 102 are intercepted, some impurities are left on the first filter assembly 102. During the movement, the flexible scraper 1031 can scrape and clean the impurities accumulated on the first filter assembly 102.

[0055] Referring to Figures 9, 10, and 11, a stepped surface 1031a is provided on the side of the flexible scraper 1031 away from the air inlet 101b. The stepped surface 1031a faces the side where the frame structure 1032 is located. The stepped surface 1031a is used to abut against the end face 1032c of the frame structure 1032 to limit the degree of sway when the flexible scraper 1031 moves toward the side where the air inlet 101b is located.

[0056] Understandably, as the cleaning component 103 moves toward the air inlet 101b, the flexible scraper 1031 will sway toward the direction away from the air inlet 101b. After the stepped surface 1031a abuts against the end face 1032c of the skeleton structure 1032, the end face 1032c of the skeleton structure 1032 restricts the swaying of the stepped surface 1031a, thereby preventing the flexible scraper 1031 from continuing to sway toward the direction away from the air inlet 101b. In other words, the degree of elastic deformation of the flexible scraper 1031 is limited, so that the flexible scraper 1031 applies a suitable elastic force to the first filter component 102, thereby maintaining the cleaning ability of the flexible scraper 1031.

[0057] The filtering device 10 of this application embodiment limits the sway of the flexible scraper 1031 by the contact between the stepped surface 1031a and the end face 1032c of the skeleton structure 1032. It does not require the rigid support set on one side of the flexible scraper 1031 as in related technologies, making the structure simpler and reducing the structural requirements of the skeleton structure 1032. It also helps to reduce the size of the cleaning component 103 along the thickness direction of the flexible scraper 1031. Compared with the technical solution of setting a rigid support on one side of the flexible scraper 1031 in related technologies, this application embodiment adopts another technical approach to solve the sway limitation of the flexible scraper 1031.

[0058] It should be noted that the specific structure of the flexible scraper 1031 is not limited.

[0059] For example, the flexible scraper 1031 can be made of materials such as rubber or silicone; the flexible scraper 1031 is an integral structure. It is understood that the flexible scraper 1031 is elastic. During the movement along the surface of the first filter assembly 102, the brush head 10311 of the flexible scraper 1031 contacts the first filter assembly 102, and the first filter assembly 102 applies a force to the flexible scraper 1031, compressing the flexible scraper 1031 in the first direction, so that the stepped surface 1031a abuts against the end face 1032c of the skeleton structure 1032. In this way, the skeleton structure 1032 can restrict the movement of the stepped surface 1031a in the first direction, thereby restricting the movement of the brush head 10311 in the first direction and improving the stability of the flexible scraper 1031 in the cleaning state.

[0060] In some embodiments, as shown in Figures 9 and 10, the flexible scraper 1031 has a natural state, in which the stepped surface 1031a and the end face 1032c are spaced apart. It is understood that in the natural state, the gap between the stepped surface 1031a and the end face 1032c of the skeleton structure 1032 reduces the constraint of the skeleton structure 1032 on the flexible scraper 1031, allowing the flexible scraper 1031 to undergo a certain degree of elastic deformation and sway.

[0061] It should be noted that the natural state refers to the state in which no external force is applied to the flexible scraper 1031, that is, the state in which the flexible scraper 1031 does not undergo elastic deformation.

[0062] Of course, in other embodiments, the flexible scraper 1031 can also maintain contact between the step surface 1031a and the end surface 1032c in its natural state.

[0063] For example, the flexible scraper 1031 is detachably connected to the frame structure 1032. It is understood that when the flexible scraper 1031 experiences significant wear and needs replacement or repair, it can be removed from the frame structure 1032, replaced, and then the new flexible scraper 1031 can be attached to the frame structure 1032. There is no need to disassemble and reassemble the frame structure 1032, thus facilitating user replacement or repair of the flexible scraper 1031 and simplifying the operation. Furthermore, since the frame structure 1032 does not need to be replaced, it can be used for a long time, saving materials and reducing operating costs. Of course, in other embodiments, the flexible scraper 1031 and the frame structure 1032 can also be connected by non-detachable methods such as welding, riveting, or bonding.

[0064] In some embodiments, referring to Figures 9 and 10, one end of the skeleton structure 1032 has a mounting groove 1032a, and the end of the flexible scraper 1031 near the skeleton structure 1032 has a connector 10312, which is accommodated in the mounting groove 1032a. It is understood that the connector 10312 and the mounting groove 1032a cooperate to achieve a detachable connection between the flexible scraper 1031 and the skeleton structure 1032. When the connector 10312 is accommodated in the mounting groove 1032a, the flexible scraper 1031 can clean the first filter assembly 102 under the action of the skeleton structure 1032. When the connector 10312 is removed from the mounting groove 1032a, the flexible scraper 1031 disengages from the skeleton structure 1032, thus facilitating the replacement and maintenance of the flexible scraper 1031.

[0065] It should be noted that the shape of the mounting groove 1032a is adapted to the shape of the connector 10312 so that the inner wall of the mounting groove 1032a can constrain the connector 10312, allowing the skeleton structure 1032 to drive the flexible scraper 1031 to move during the movement.

[0066] It should be noted that the specific matching method between the connector 10312 and the mounting groove 1032a is not limited, as long as a detachable connection between the flexible scraper 1031 and the frame structure 1032 can be achieved.

[0067] In some embodiments, referring to Figures 2, 4, 5, and 9, the skeleton structure 1032 includes a pivot mounting portion 10322 and a frame 10321. The pivot mounting portion 10322 is rotatably connected to the housing 101, and the frame 10321 connects the pivot mounting portion 10322 and the flexible scraper 1031. It is understood that during rotation, the skeleton structure 1032 enables the flexible scraper 1031 to remain in contact with the first filter assembly 102, thereby cleaning the first filter assembly 102. Furthermore, the skeleton structure 1032 can rotate around the axis of its pivot mounting portion 10322 under external force, thereby driving the flexible scraper 1031 to move, so that the flexible scraper 1031 cleans the first filter assembly 102.

[0068] In some embodiments, referring to FIG2, the housing 101 has a first sidewall 101h1, and one end of the first filter assembly 102 is close to the first sidewall 101h1. It should be noted that the first sidewall 101h1 is located at the end of the first filter assembly 102 away from the air inlet 101b.

[0069] In some embodiments, the flexible scraper 1031 is used to abut against the first sidewall 101h1 to maintain a distance between the skeleton structure 1032 and the first sidewall 101h1. It is understood that the flexible scraper 1031 can act as a buffer; when the cleaning assembly 103 collides with the first sidewall 101h1 during movement, the flexible scraper 1031 contacts the first sidewall 101h1 and absorbs some of the energy generated by the collision, reducing damage and impact noise to the skeleton structure 1032 caused by the collision with the first sidewall 101h1.

[0070] In some embodiments, along a direction perpendicular to the plane of the flexible scraper 1031, the portion of the flexible scraper 1031 that abuts against the first sidewall 101h1 extends beyond the surface of the frame 10321 on the side away from the air inlet 101b. This ensures that when the flexible scraper 1031 abuts against the first sidewall 101h1, a gap exists between the frame 10321 and the first sidewall 101h1, preventing the frame 10321 from impacting the first sidewall 101h1.

[0071] In some embodiments, along a direction perpendicular to the plane of the flexible scraper 1031, the portion of the flexible scraper 1031 that abuts against the first sidewall 101h1 is flush with the end of the pivot mounting portion 10322. This ensures that when the cleaning assembly 103 contacts the first sidewall 101h1, the frame structure 1032 will not contact the first sidewall 101h1 before the flexible scraper 1031, thus reducing the possibility of damage to the frame structure 1032 due to contact with the first sidewall 101h1.

[0072] In some embodiments, referring to Figures 6 to 8, both the end face 1032c and the stepped surface 1031a of the skeleton structure 1032 extend along the second direction, and the length of the stepped surface 1031a along the second direction is not less than half the length of the end face 1032c along the second direction. It is understood that this increases the contact area between the stepped surface 1031a and the end face 1032c of the skeleton structure 1032, enhances the support force of the skeleton structure 1032 on the flexible scraper 1031, and strengthens the limitation on the degree of deflection of the flexible scraper 1031 by the skeleton structure 1032 during movement.

[0073] It should be noted that the first and second directions intersect.

[0074] It should be noted that the specific formation method of step surface 1031a is not limited.

[0075] For example, the stepped surface 1031a can be formed by a recessed portion of the flexible scraper 1031 away from the air inlet 101b, or it can be formed by a protruding portion of the flexible scraper 1031 away from the air inlet 101b.

[0076] In some embodiments, referring to Figures 9 to 11, the flexible scraper 1031 includes a scraper body 10313 and a protrusion 10314. The protrusion 10314 protrudes from the surface of the scraper body 10313, and the side of the protrusion 10314 facing the skeleton structure 1032 forms a stepped surface 1031a. It is understood that the protrusion 10314 not only forms a stepped surface 1031a for abutting against the end face 1032c of the skeleton structure 1032, but also improves the structural strength of the flexible scraper 1031 and enhances the stability of the flexible scraper 1031 during movement.

[0077] In some embodiments, the end of the protrusion 10314 away from the scraper body 10313 is used to abut against the first sidewall 101h1, so that the skeleton structure 1032 and the first sidewall 101h1 are kept apart. Specifically, along the direction perpendicular to the plane where the flexible scraper 1031 is located, the end of the protrusion 10314 extends beyond the surface of the skeleton 10321 on the side away from the air inlet 101b. It can be understood that the protrusion 10314 can form a stepped surface 1031a for abutting against the end face 1032c of the skeleton structure 1032, and can also be used to abut against the first sidewall 101h1, so that the structure of the flexible scraper 1031 is compact, which is conducive to the miniaturization of the flexible scraper 1031.

[0078] In some embodiments, referring to Figures 9 to 11, the flexible scraper 1031 includes a damping protrusion 10315. The damping protrusion 10315 is located on the side of the scraper body 10313 away from the air inlet 101b. The damping protrusion 10315 is used to abut against the first sidewall 101h1 to keep the frame structure 1032 spaced from the first sidewall 101h1. It is understood that the damping protrusion 10315 can play a buffering role. When the cleaning component 103 collides with the first sidewall 101h1 during movement, the damping protrusion 10315 can absorb part of the energy generated by the collision, reducing the damage and impact noise caused by the collision between the frame structure 1032 and the first sidewall 101h1.

[0079] Specifically, along a direction perpendicular to the plane of the flexible scraper 1031, the end of the damping protrusion 10315 extends beyond the surface of the frame 10321 on the side away from the air inlet 101b. In this way, the damping protrusion 10315 can ensure that the frame 10321 will not impact the first sidewall 101h1.

[0080] It should be noted that the specific positional relationship between the vibration damping protrusion 10315 and the protrusion 10314 is not limited.

[0081] In some embodiments, at least one damping protrusion 10315 and a protrusion 10314 are spaced apart on the surface of the scraper body 10313, and the degree of protrusion of the damping protrusion 10315 on the surface of the scraper body 10313 is greater than that of the protrusion 10314. It is understood that when the flexible scraper 1031 collides with the first sidewall 101h1, the damping protrusion 10315 contacts the first sidewall 101h1 before the protrusion 10314, thereby reducing the collision energy absorbed by the protrusion 10314. This improves the service life of the protrusion 10314 and also enhances the stability of the contact between the stepped surface 1031a formed by the protrusion 10314 and the end face 1032c of the frame structure 1032.

[0082] In other embodiments, referring to Figures 9 to 11, at least one damping protrusion 10315 is disposed at the end of the protrusion 10314 away from the scraper body 10313. In this way, on the one hand, the structure of the flexible scraper 1031 can be made compact; on the other hand, the protrusion degree of the damping protrusion 10315 can be increased, thereby increasing the distance between the skeleton structure 1032 and the first sidewall 101h1.

[0083] It should be noted that the specific number of vibration damping protrusions 10315 and protrusions 10314 is not limited; there can be one or more. For example, referring to Figure 7, there are multiple vibration damping protrusions 10315, which are arranged at intervals along the second direction. For example, referring to Figure 7, there is one protrusion 10314.

[0084] In some embodiments, referring to Figures 9 and 10, the flexible scraper 1031 has a brush head 10311 at the end away from the skeleton structure 1032. It is understood that during movement, the brush head 10311 can contact the first filter assembly 102 and scrape away impurities accumulated on the first filter assembly 102. The two opposite ends of the flexible scraper 1031 along a first direction are a connector 10312 and a brush head 10311, respectively. The force on the connector 10312 can be transmitted to the brush head 10311, allowing the brush head 10311 to move along the surface of the first filter assembly 102. Furthermore, the flexible scraper 1031 can also be moderately bent, so that the brush head 10311 applies a moderate elastic force to the first filter assembly 102.

[0085] In some embodiments, referring to FIG11, the surface of the brush head 10311 includes a smooth surface 10311a and a scraping surface 10311b, and the junction of the smooth surface 10311a and the scraping surface 10311b forms a corner for scraping the object. It is understood that the frictional force generated by the contact between the smooth surface 10311a and the surface of the first filter assembly 102 is small, which facilitates the movement of the brush head 10311 on the surface of the first filter assembly 102. During the movement, the corner of the brush head 10311 can more easily scrape up the impurities accumulated on the first filter assembly 102, thereby improving the cleaning ability of the brush head 10311 on the first filter assembly 102 during the movement.

[0086] In some embodiments, the corner is located on the side of the brush head 10311 facing the air inlet 101b. When the brush head 10311 moves towards the air inlet 101b, the corner contacts the surface of the first filter assembly 102, increasing the friction between them and improving the ability of the brush head 10311 to scrape impurities towards the air inlet 101b. When the brush head 10311 moves away from the air inlet 101b, the smooth surface 10311a contacts the surface of the first filter assembly 102, reducing the friction and allowing the brush head 10311 to move smoothly on the surface of the first filter assembly 102. In other words, the resistance to movement of the brush head 10311 when moving towards the air inlet 101b is greater than the resistance when moving away from the air inlet 101b.

[0087] For example, referring to FIG11, the scraping surface 10311b is located on the side of the brush head 10311 facing the air inlet 101b. The surface of the scraping surface 10311b has a groove 10311c, which extends along the second direction. It is understood that the brush head 10311 is elastic. When the brush head 10311 moves toward the air inlet 101b, the corner contacts the surface of the first filter assembly 102. The brush head 10311 is deflected under the combined action of the friction force of the first filter assembly 102 and the thrust of the skeleton structure 1032, so that at least a portion of the scraping surface 10311b contacts the surface of the first filter assembly 102. In this way, the groove 10311c on the scraping surface 10311b can improve the ability of the scraping surface 10311b to scrape impurities on the first filter assembly 102.

[0088] In some embodiments, referring to Figures 6 and 7, the skeleton structure 1032 has a weight-reducing groove 1032b. It is understood that the weight-reducing groove 1032b can reduce the weight of the skeleton structure 1032, facilitating its movement under external forces and thus improving user convenience.

[0089] In some embodiments, referring to FIG2, the flexible scraper 1031 has an initial position in which it is located at the end of the first filter assembly 102 away from the air inlet 101b. It is understood that in the initial position, the obstruction of the airflow from the air inlet 101b to the air outlet 101c by the flexible scraper 1031 can be reduced, and internal space of the filter device 10 can also be saved.

[0090] Referring to Figure 3, the flexible scraper 1031 has an end position. In the end position, the flexible scraper 1031 is located at the end of the first filter assembly 102 near the air inlet 101b. The flexible scraper 1031 moves between the initial position and the end position. It can be understood that the flexible scraper 1031 can scrape impurities on the surface of the first filter assembly 102 toward the air inlet 101b, facilitating the removal of impurities from the filter device 10 through the air inlet 101b.

[0091] It should be noted that in the embodiment where the flexible scraper 1031 has a scraping surface 10311b and a groove 10311c, both the scraping surface 10311b and the groove 10311c are located on the side of the flexible scraper 1031 facing the air inlet 101b.

[0092] For example, referring to Figures 2 and 3, the first filter assembly 102 has at least an arc-shaped segment, with the cleaning assembly 103 and the air inlet 101b located on the concave side of the arc-shaped segment. It is understood that the arc-shaped segment of the first filter assembly 102 increases its effective area, thereby increasing the filtration area of ​​the first filter assembly 102 for airflow. Simultaneously, the airflow through the first filter assembly increases, thus improving the filtration efficiency of the first filter assembly 102.

[0093] In some embodiments, referring to Figure 3, the filter device 10 further includes a force-applying member 104, which is disposed outside the housing 101. The force-applying member 104 is used to drive the frame structure 1032 to rotate, so that the frame structure 1032 drives the flexible scraper 1031 to move. It is understood that the force-applying member 104 does not occupy the space inside the housing 101, leaving space for more airflow to enter the housing 101, thereby improving the filtration efficiency of the filter device 10.

[0094] The method by which the force-applying component 104 drives the frame 10321 assembly is not limited. For example, in some embodiments, the force-applying component 104 has a power source, such as a motor, which can drive automatically without requiring user force. In other embodiments, the force-applying component 104 is a non-powered mechanism, requiring the user to manually apply force to the force-applying component 104 to force it to move, thereby driving the frame structure 1032 to move.

[0095] In some embodiments, referring to Figures 1, 2, and 3, the housing 101 includes a side wall 101h, which connects the top wall 101f and the bottom wall. An air inlet 101b and an air outlet 101c are respectively located on different sides of the side wall 101h. This allows for full utilization of the area of ​​the side wall 101h of the housing 101, resulting in larger areas for the air inlet 101b and the air outlet 101c, thereby increasing airflow and improving filtration area and efficiency.

[0096] In some embodiments, referring to FIG1, the housing 101 has a handle assembly 108 at a second end along a third direction. Thus, when the filter device 10 is installed in an object, the filter device 10 can be pulled out of the object via the handle assembly 108.

[0097] For example, referring to FIG1, the filter device 10 includes a sealing structure 107 disposed outside the third-direction first end of the housing 101 and surrounding the air inlet 101b. It is understood that when the handle assembly 108 is pushed along the third-direction first end, the mating effect between the air inlet 101b and the sealing structure 107 is enhanced, thereby improving the sealing performance of the sealing structure 107.

[0098] Understandably, after the filter device 10 is installed on the object, the sealing structure 107 seals the gap between the filter device 10 and the object, improving the waterproof rating at the connection between the filter device 10 and the object. For example, it can achieve a waterproof rating of IP65 (full name: Ingress Protection 65, which means completely dustproof and can prevent the intrusion of sprayed water).

[0099] In some embodiments, referring to FIG3, the first filter assembly 102 includes a first support frame 1021 and a first filter screen 1022 disposed on the first support frame 1021. In this way, the first support frame 1021 can provide support for the first filter screen 1022, so that the first filter screen 1022 maintains its filtering capacity under the impact of airflow.

[0100] In some embodiments, referring to FIG3, the filtering device 10 further includes a second filtering component 105. Along the airflow direction, the second filtering component 105 is disposed upstream of the air outlet 101c, or at the air outlet 101c. In this way, the airflow flowing out of the receiving space 101a must pass through the second filtering component 105 before flowing out of the air outlet 101c, so that the airflow filtered by the first filtering component 102 undergoes a second filtration by the second filtering component 105, further improving the filtration effect of the filtering device 10.

[0101] For example, the second filter assembly 105 is detachably connected to the housing 101. This facilitates the removal of the second filter assembly 105 from the housing 101, making it easier to replace, clean, or repair the second filter assembly 105.

[0102] The method by which the second filter component 105 is detachably connected to the housing 101 is not limited, such as screw connection, sliding connection, snap-fit, etc., and no restrictions are imposed here.

[0103] In some embodiments, referring to Figure 3, the second filter assembly 105 can be pulled out of the housing 101 from one end in the third direction. Pulling out of the housing 101 means that the second filter assembly 105 is completely separated from the housing 101, thus facilitating manual disassembly of the second filter assembly 105. In this embodiment, the handle assembly 108 does not interfere with the extraction of the second filter assembly 105; the two do not interfere with each other. Furthermore, when the filter device 10 is placed into an object, the side with the handle assembly 108 is generally the exterior surface, and the extraction structure reserved for the second filter assembly 105 at the first end of the housing 101 in the third direction does not affect the appearance of the filter device 10. In addition, when the second filter assembly 105 is pulled out of the housing 101 from the first end in the third direction, force can be applied to the second end of the handle assembly 108 in the third direction to more easily extract the second filter assembly 105 from the housing 101.

[0104] For example, referring to FIG3, the second filter assembly 105 includes a second support frame 1051 and a second filter screen 1052 connected to the second support frame 1051. The second support frame 1051 can provide support for the second filter screen 1052 so that the second filter screen 1052 maintains its filtering capacity under the impact of airflow.

[0105] For example, referring to FIG3, the housing 101 has a guide rail groove 101d adapted to the second support frame 1051. The second support frame 1051 is disposed in the guide rail groove 101d. The guide rail groove 101d extends along the second direction and penetrates the end face 1032c of the housing 101 and defines a bayonet 101d1. The bayonet 101d1 is used for the second support frame 1051 to be pulled out to the outside of the guide rail groove 101d. The second filter assembly 105 is pulled out from the second end of the housing 101 along the third direction through the guide rail groove 101d and the bayonet 101d1.

[0106] The application scenarios of the filter device 10 in this application embodiment are not limited. This application embodiment describes the filter device 10 applied to the garment processing equipment 1 as an example. It can be understood that the filter device 10 can also be applied to other products.

[0107] This application provides a garment processing device 1, as shown in Figures 11 and 12, which includes a cylindrical assembly 11, a housing 12, a base 13, and a filter device 10 of any of the above embodiments.

[0108] The tubular assembly 11 has a garment processing chamber 11a, an air inlet, and an air outlet. The tubular assembly 11 is disposed inside a housing 12, which has a first opening 12a.

[0109] The base 13 has an air duct 13a that connects an air inlet and an air outlet to form a circulating air duct 13a with the clothing processing chamber 11a. The filter device 10 is removably installed on the airflow path of the air duct 13a and can be pulled out of the housing 12 through the first port 12a.

[0110] Clothing processing equipment 1 can be a dryer, washer-dryer combo, etc., and there are no restrictions here.

[0111] Exemplarily, the drying principle of the clothing processing device 1 is as follows: Dry hot airflow in the air duct 13a enters the clothing processing chamber 11a downstream of the airflow direction through the air inlet. In the clothing processing chamber 11a, the dry hot airflow flows over the surface of the wet clothing, exchanging heat and moisture with the clothing, absorbing moisture from the clothing, and becoming humid hot airflow. The humid hot airflow then enters the upstream of the air duct 13a through the air outlet, flowing sequentially through the condenser and dehumidifier and the heating element. During the flow through the condenser and dehumidifier, water vapor in the humid hot airflow is cooled and condenses into water droplets. After being condensed and dehumidified by the condenser and dehumidifier, the humid hot airflow forms a low-temperature dry airflow. When the low-temperature dry airflow passes through the heating element, it is heated into a dry hot airflow. The dry hot airflow then re-enters the clothing processing chamber 11a downstream of the air duct 13a, and this cycle repeats, achieving continuous and efficient drying of the clothing.

[0112] It should be noted that the low-temperature dry airflow is relative to the humid and hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid and hot airflow. In the embodiments of this application, the low temperature can be room temperature.

[0113] In some embodiments, the condensation dehumidification component can be the evaporator 15 in a heat pump system, and the heating component can be the condenser 16 in a heat pump system. In other embodiments, the condensation dehumidification component can dehumidify the airflow by condensing water, and the heating component can be resistance wire heating, etc.

[0114] In some embodiments, referring to FIG11, the laundry treatment device 1 includes a detergent dispenser 14, and a filter device 10 is located above the detergent dispenser 14. This arrangement of the filter device 10 conforms to user habits and enhances the user experience.

[0115] In some embodiments, referring to Figures 2 and 12, the air duct 13a has a connecting interface 13a1, and the air inlet 101b of the housing 101 is disposed on the side wall 101h (hereinafter referred to as the rear side wall 101h2) at one end of the housing 101 along a third direction. The rear side wall 101h2 of the housing 101 is sealed and connected to the connecting interface 13a1 along a third direction. It should be noted that the rear side wall 101h2 of the housing 101 refers to the end of the housing 101 away from the handle assembly 108 along a third direction. It can be understood that the airflow flows through the connecting interface 13a1 of the air duct 13a to the air inlet 101b and enters the filter device 10 for filtration. The sealed connection between the rear side wall 101h2 of the housing 101 and the connecting interface 13a1 along a third direction reduces the leakage of airflow during its flow to the air inlet 101b.

[0116] In some embodiments, referring to FIG12, the base 13 has a transition cavity 13b, a first mounting cavity 13c, and a second mounting cavity 13d. A filter device 10 is disposed in the first mounting cavity 13c. The garment processing device 1 includes an evaporator 15 and a condenser 16, which are disposed in the second mounting cavity 13d. The transition cavity 13b is connected to an air outlet. The transition cavity 13b is located behind the first mounting cavity 13c, and the junction between the two defines a mating interface 13a1. It is understood that the airflow is filtered by the filter device 10 before flowing to the evaporator 15 and condenser 16, reducing the amount of lint adhering to the evaporator 15 and condenser 16 and improving the heat exchange effect between the airflow and the evaporator 15 and condenser 16.

[0117] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0118] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
