Description

Technical Field

[0001] The present application relates to the technical field of clothing processing equipment, and in particular to a filtering device and clothing processing equipment. Background Art

[0002] Take the filter device of the clothing processing equipment as an example. During the use of the filter device, impurities such as hair scraps remain in the filter device. In the related art, a flexible scraper is used to scrape and clean the filter. In this solution, a hard bracket needs to be set on one side of the plate surface of the flexible scraper to support the flexible scraper so that the flexible scraper will not be excessively deformed, which is convenient for applying a suitable elastic force to the filter. However, this structure requires a special hard bracket to support the flexible scraper. The part where the flexible scraper contacts the end of the hard bracket is prone to shear force and cracking. If the shear force is to be improved, the end of the hard bracket needs to be designed into a spherical shape. This will increase the requirements for the structure of the hard bracket and also increase the size in the thickness direction perpendicular to the flexible scraper. Utility Model Content

[0003] In view of this, the embodiments of the present application hope to provide a filtering device and a clothing processing device to ensure the cleaning ability of the flexible scraper while reducing the structural requirements of the hard bracket.

[0018] The flexible scraper includes a vibration-damping protrusion, which is located on a side of the scraper body away from the air inlet, and is used to abut against the first side wall to keep the skeleton structure spaced apart from the first side wall.

[0019] In some embodiments, at least one of the vibration-damping protrusions and the protrusions are spaced apart on the surface of the scraper body, and the protrusion degree of the protrusion on the surface of the scraper body is greater than the protrusion degree of the protrusion; and / or, at least one of the vibration-damping protrusions is arranged at an end of the protrusion away from the scraper body.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 A first aspect of an embodiment of the present application provides a filtering device 10 , comprising: a box body 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] See also Figure 2 and Figure 3 , the box body 101 has an air inlet 101b and an air outlet 101c. Specifically, the box body 101 has a receiving space 101a inside, and the receiving space 101a communicates with the air inlet 101b and the air outlet 101c. It can be understood that the airflow outside the box body 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 in the box body 101, and is used to filter the airflow passing through the box body 101. It is understandable that the airflow passing through the box body 101 can pass through the first filter assembly 102, and the first filter assembly 102 can intercept impurities in the airflow, so that the content of impurities in the airflow flowing out of the box body 101 is reduced.

[0053] Please refer to Figure 4 and Figure 5 The cleaning assembly 103 is at least partially disposed inside the box body 101. The cleaning assembly 103 includes a skeleton structure 1032 and a flexible scraper 1031, and the flexible scraper 1031 is connected to one end of the skeleton structure 1032 along the first direction. In this way, the cleaning assembly 103 is compact.

[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 the movement and cleans the first filter assembly 102. It can be understood that after the impurities in the airflow passing through the first filter assembly 102 are intercepted, some of the impurities are left on the first filter assembly 102. During the movement of the flexible scraper 1031, the flexible scraper 1031 can scrape and clean the impurities accumulated on the first filter assembly 102.

[0055] Please refer to Fig. 9 , Fig.10 and Fig.11 A step surface 1031a is provided on the side of the flexible scraper 1031 away from the air inlet 101b, and the step surface 1031a faces the side where the skeleton structure 1032 is located. The step surface 1031a is used to abut against the end surface 1032c of the skeleton structure 1032 to limit the degree of deflection of the flexible scraper 1031 when it moves toward the side where the air inlet 101b is located.

[0056] It can be understood that when the cleaning component 103 moves toward the direction approaching the air inlet 101b, the flexible scraper 1031 will swing toward the direction away from the air inlet 101b, and after the step surface 1031a abuts against the end surface 1032c of the skeleton structure 1032, the end surface 1032c of the skeleton structure 1032 limits the swing of the step surface 1031a, thereby preventing the flexible scraper 1031 from continuing to swing in the direction away from the air inlet 101b as a whole. In other words, the elastic deformation degree of the flexible scraper 1031 is limited, so that the flexible scraper 1031 exerts a suitable elastic force on the first filter component 102, thereby maintaining the cleaning ability of the flexible scraper 1031.

[0057] The filtering device 10 of the embodiment of the present application limits the degree of deflection of the flexible scraper 1031 by abutting the step surface 1031a with the end surface 1032c of the skeleton structure 1032. There is no need to adopt the hard bracket set on one side of the flexible scraper 1031 in the related art. The structure is simpler, and the structural requirements for the skeleton structure 1032 can be reduced. It is also beneficial 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 hard bracket on one side of the flexible scraper 1031 in the related art, the embodiment of the present application adopts another technical thinking to solve the deflection limitation of the flexible scraper 1031.

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

[0059] Exemplarily, the flexible scraper 1031 can be made of materials such as rubber or silicone; the flexible scraper 1031 is an integrated structure. It can be understood that the flexible scraper 1031 has elasticity. During the movement along the surface of the first filter component 102, the brush head 10311 of the flexible scraper 1031 contacts the first filter component 102. The first filter component 102 applies a force to the flexible scraper 1031, compressing the flexible scraper 1031 along the first direction so that the step surface 1031a abuts against the end surface 1032c of the skeleton structure 1032. In this way, the skeleton structure 1032 can limit the movement of the step surface 1031a along the first direction, thereby limiting the movement of the brush head 10311 along the first direction, and improving the stability of the flexible scraper 1031 in the cleaning state.

[0060] In some embodiments, Fig. 9 and Fig.10 , the flexible scraper 1031 has a natural state, in which the step surface 1031a and the end surface 1032c are spaced apart. It is understandable that in the natural state, there is a gap between the step surface 1031a and the end surface 1032c of the skeleton structure 1032, which can reduce the constraint of the skeleton structure 1032 on the flexible scraper 1031 and allow the flexible scraper 1031 to undergo a certain degree of elastic deformation and deflection.

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

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

[0063] Exemplarily, the flexible scraper 1031 is detachably connected to the skeleton structure 1032. It is understandable that when the flexible scraper 1031 is greatly worn and needs to be replaced or repaired, the flexible scraper 1031 is removed from the skeleton structure 1032, and after replacement, the new flexible scraper 1031 is connected to the skeleton structure 1032, without the need to disassemble and install the skeleton structure 1032. In this way, it is convenient for users to replace or repair the flexible scraper 1031, and the operation is relatively simple; in addition, there is no need to replace the skeleton structure 1032, and the skeleton structure 1032 can be used for a long time, saving materials and reducing the cost of use. Of course, in other embodiments, the flexible scraper 1031 and the skeleton structure 1032 can also be connected by a non-detachable connection method such as welding, riveting, and bonding.

[0064] In some embodiments, please refer to Fig. 9 and Fig.10 , one end of the skeleton structure 1032 has a mounting groove 1032a, and one end of the flexible scraper 1031 close to the skeleton structure 1032 has a connector 10312, and the connector 10312 is accommodated in the mounting groove 1032a. It can be understood that the flexible scraper 1031 and the skeleton structure 1032 are detachably connected through the mutual cooperation of the connector 10312 and the mounting groove 1032a. When the connector 10312 is accommodated in the mounting groove 1032a, the flexible scraper 1031 can clean the first filter assembly 102 under the drive of the skeleton structure 1032; when the connector 10312 is pulled out of the mounting groove 1032a, the flexible scraper 1031 is out of contact with the skeleton structure 1032, so that the flexible scraper 1031 can be easily replaced and repaired.

[0065] It should be noted that the shapes of the mounting groove 1032a and the connecting head 10312 are adapted to each other so that the inner wall of the mounting groove 1032a can constrain the connecting head 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 connecting head 10312 and the installation groove 1032a is not limited, as long as a detachable connection between the flexible scraper 1031 and the skeleton structure 1032 can be achieved.

[0067] In some embodiments, please refer to Figure 2 , Figure 4 , Figure 5 and Fig. 9 The skeleton structure 1032 includes a shaft mounting portion 10322 and a skeleton 10321. The shaft mounting portion 10322 is rotatably connected to the box body 101, and the skeleton 10321 connects the shaft mounting portion 10322 and the flexible scraper 1031. It can be understood that during the rotation of the skeleton structure 1032, the flexible scraper 1031 can maintain contact with the first filter assembly 102 to clean the first filter assembly 102. In addition, the skeleton structure 1032 can rotate around the axis of its shaft mounting portion 10322 under the action of an 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, please refer to Figure 2 The box body 101 has a first side wall 101h1, and one end of the first filter assembly 102 is close to the first side wall 101h1. It should be noted that the first side wall 101h1 is located at one 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 side wall 101h1 so that the skeleton structure 1032 is spaced apart from the first side wall 101h1. It is understandable that the flexible scraper 1031 can play a buffering role. When the cleaning component 103 collides with the first side wall 101h1 during movement, the flexible scraper 1031 contacts the first side wall 101h1 and absorbs part of the energy generated by the collision, thereby reducing the damage and impact sound caused by the collision between the skeleton structure 1032 and the first side wall 101h1.

[0070] In some embodiments, along a direction perpendicular to the plane where the flexible scraper 1031 is located, the portion of the flexible scraper 1031 that is used to abut against the first side wall 101h1 exceeds the surface of the frame 10321 on the side away from the air inlet 101b. In this way, when the flexible scraper 1031 abuts against the first side wall 101h1, a gap can be ensured between the frame 10321 and the first side wall 101h1, so that the frame 10321 will not hit the first side wall 101h1.

[0071] In some embodiments, along a direction perpendicular to the plane where the flexible scraper 1031 is located, the portion of the flexible scraper 1031 that is used to abut against the first side wall 101h1 is flush with the end of the shaft mounting portion 10322. In this way, when the cleaning assembly 103 contacts the first side wall 101h1, the skeleton structure 1032 will not contact the first side wall 101h1 before the flexible scraper 1031, thereby reducing the possibility of the skeleton structure 1032 being damaged by contact with the first side wall 101h1.

[0072] In some embodiments, please refer to Figure 6 to Figure 8 , the end surface 1032c of the skeleton structure 1032 and the step surface 1031a both extend along the second direction, and the length of the step surface 1031a along the second direction is not less than 1 / 2 of the length of the end surface 1032c along the second direction. It can be understood that the contact surface between the step surface 1031a and the end surface 1032c of the skeleton structure 1032 can be improved, the support force of the skeleton structure 1032 on the flexible scraper 1031 can be enhanced, and the restriction of the deflection degree of the flexible scraper 1031 by the skeleton structure 1032 during the movement can be strengthened.

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

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

[0075] Exemplarily, the step surface 1031a may be formed by a depression of a part of the side of the flexible scraper 1031 away from the air inlet 101b, or may be formed by a protrusion of a part of the side of the flexible scraper 1031 away from the air inlet 101b.

[0076] In some embodiments, please refer 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. The side of the protrusion 10314 facing the side where the skeleton structure 1032 is located forms a step surface 1031a. It can be understood that the protrusion 10314 can not only form the step surface 1031a for abutting against the end surface 1032c of the skeleton structure 1032, but also improve the structural strength of the flexible scraper 1031 and enhance 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 side wall 101h1, so that the skeleton structure 1032 is spaced apart from the first side wall 101h1. Specifically, along the direction perpendicular to the plane where the flexible scraper 1031 is located, the end of the protrusion 10314 exceeds the surface of the skeleton 10321 away from the air inlet 101b. It can be understood that the protrusion 10314 can form a step surface 1031a for abutting against the end surface 1032c of the skeleton structure 1032, and can also be used to abut against the first side wall 101h1, so that the structure of the flexible scraper 1031 is compact, which is conducive to the miniaturization of the structure of the flexible scraper 1031.

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

[0079] Specifically, along a direction perpendicular to the plane where the flexible scraper 1031 is located, the end of the vibration reduction protrusion 10315 exceeds the surface of the frame 10321 away from the air inlet 101b. In this way, the vibration reduction protrusion 10315 can ensure that the frame 10321 does not hit the first side wall 101h1.

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

[0081] In some embodiments, at least one vibration-damping protrusion 10315 and the protrusion 10314 are arranged at intervals on the surface of the scraper body 10313, and the protrusion degree of the vibration-damping protrusion 10315 on the surface of the scraper body 10313 is greater than the protrusion degree of the protrusion 10314. It can be understood that when the flexible scraper 1031 collides with the first side wall 101h1, the vibration-damping protrusion 10315 contacts the first side wall 101h1 before the protrusion 10314, which can reduce the collision energy absorbed by the protrusion 10314. In this way, the service life of the protrusion 10314 can be improved, and the stability of the step surface 1031a formed by the protrusion 10314 and the end surface 1032c of the skeleton structure 1032 can be improved.

[0082] In some other embodiments, please refer to Figures 9 to 11 At least one vibration-damping protrusion 10315 is disposed at one 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 vibration-damping protrusion 10315 can be increased, and the distance between the skeleton structure 1032 and the first side wall 101h1 can be increased.

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

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

[0085] In some embodiments, please refer to Fig.11The surface of the brush head 10311 includes a smooth surface 10311a and a scraping surface 10311b, and the connection between the smooth surface 10311a and the scraping surface 10311b forms a corner for scraping an object. It can be understood that the friction generated by the contact between the smooth surface 10311a and the surface of the first filter component 102 is small, which facilitates the movement of the brush head 10311 on the surface of the first filter component 102. During the movement of the brush head 10311, the corner can easily scrape up the impurities accumulated on the first filter component 102, which can improve the cleaning ability of the brush head 10311 on the first filter component 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 in the direction of the air inlet 101b, the corner contacts the surface of the first filter assembly 102, which can increase the friction between the two, so as to improve the ability of the brush head 10311 to scrape impurities toward the air inlet 101b. When the brush head 10311 moves in the direction away from the air inlet 101b, the smooth surface 10311a contacts the surface of the first filter assembly 102, which can reduce the friction between the two, so that the brush head 10311 moves smoothly on the surface of the first filter assembly 102. In other words, the movement resistance of the brush head 10311 when it moves in the direction of the air inlet 101b is greater than the resistance of the brush head 10311 when it moves in the direction away from the air inlet 101b.

[0087] For example, please refer to Fig.11 The scraping surface 10311b is located on the side of the brush head 10311 facing the air inlet 101b, and the surface of the scraping surface 10311b has a groove 10311c, and the groove 10311c extends along the second direction. It can be 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 component 102. The brush head 10311 is deflected by the friction force of the first filter component 102 and the thrust of the skeleton structure 1032, so that at least a part of the scraping surface 10311b contacts the surface of the first filter component 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 component 102.

[0088] In some embodiments, please refer to Figure 6 and Figure 7 The skeleton structure 1032 has a weight-reducing groove 1032b. It is understandable that the weight-reducing groove 1032b can reduce the weight of the skeleton structure 1032, making it easier for the skeleton structure 1032 to move under the action of an external force, thereby improving the user's convenience in operation.

[0089] In some embodiments, please refer to Figure 2 The flexible scraper 1031 has an initial position, in which the flexible scraper 1031 is located at an end of the first filter assembly 102 away from the air inlet 101b. It is understandable that in the initial position, the flexible scraper 1031 can reduce the obstruction of the airflow from the air inlet 101b to the air outlet 101c, and the internal space of the filter device 10 can be saved.

[0090] Please refer to Figure 3 The flexible scraper 1031 has an end position, in which the flexible scraper 1031 is located at one end of the first filter assembly 102 close to the air inlet 101b, and 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, so as to clean the impurities out of the filter device 10 through the air inlet 101b.

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

[0092] For example, please refer to Figure 2 and Figure 3 , the first filter assembly 102 has at least an arc segment, and the cleaning assembly 103 and the air inlet 101b are located on the concave side of the arc segment. It can be understood that the arc segment of the first filter assembly 102 can increase the effective area of ​​the first filter assembly 102, thereby increasing the filtering area of ​​the first filter assembly 102 for the airflow, and at the same time, the amount of air flowing through the first filter group increases, thereby improving the filtering efficiency of the first filter assembly 102.

[0093] In some embodiments, please refer to Figure 3 The filter device 10 further includes a force member 104, which is disposed outside the box body 101 and is used to drive the skeleton structure 1032 to rotate, so that the skeleton structure 1032 drives the flexible scraper 1031 to move. It can be understood that the force member 104 does not occupy the space inside the box body 101, and the space is reserved to allow more airflow to enter the box body 101, thereby improving the filtering efficiency of the filter device 10.

[0094] The force member 104 drives the skeleton 10321 assembly in any manner. For example, in some embodiments, the force member 104 has a power source, such as a motor, and can be driven automatically without the user applying force. In other embodiments, the force member 104 is a non-powered mechanism, and the user needs to manually apply force to the force member 104 to force the force member 104 to move, thereby driving the skeleton structure 1032 to move through the force member 104.

[0095] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The box body 101 includes a side wall 101h, the side wall 101h is connected to the top wall 101f and the bottom wall, and the air inlet 101b and the air outlet 101c are respectively arranged on the side wall 101h on different sides. In this way, the area of ​​the side wall 101h of the box body 101 can be fully utilized, so that the area of ​​the air inlet 101b and the air outlet 101c are respectively larger, which can increase the flow of airflow, improve the filtering area and filtering efficiency.

[0096] In some embodiments, please refer to Figure 1 The second end of the box body 101 along the third direction has a handle assembly 108. In this way, when the filter device 10 is installed in an object, the filter device 10 can be pulled out of the object through the handle assembly 108.

[0097] For example, please refer to Figure 1 The filter device 10 includes a sealing structure 107, which is disposed outside the first end of the box body 101 in the third direction and surrounds the air inlet 101b. It can be understood that when the handle assembly 108 is pushed along the first end of the third direction, the docking effect between the air inlet 101b and the sealing structure 107 is enhanced, thereby improving the sealing performance of the sealing structure 107.

[0098] It can be understood that 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, thereby improving the waterproof level of the connection between the filter device 10 and the object. For example, the waterproof level can reach IP65 (full name: Ingress Protection 65, which means completely dustproof and can prevent jet water intrusion).

[0099] In some embodiments, please refer to Figure 3 , 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 force for the first filter screen 1022, so that the first filter screen 1022 maintains filtering capacity under the impact of airflow.

[0100] In some embodiments, please refer to Figure 3The filter device 10 further includes a second filter assembly 105. The second filter assembly 105 is disposed upstream of the air outlet 101c along the air flow direction, or the second filter assembly 105 is disposed at the air outlet 101c. In this way, the airflow flowing out of the accommodation space 101a needs to pass through the second filter assembly 105 before flowing out through the air outlet 101c, so that the airflow filtered by the first filter assembly 102 is filtered for the second time by the second filter assembly 105, further improving the filtering effect of the filter device 10.

[0101] Exemplarily, the second filter assembly 105 is detachably connected to the box body 101. In this way, it is convenient to remove the second filter assembly 105 from the box body 101, so as to facilitate replacement, cleaning, or maintenance of the second filter assembly 105.

[0102] The second filter assembly 105 and the box body 101 may be detachably connected in any manner, such as screw connection, sliding connection, snap connection, etc., which are not limited here.

[0103] In some embodiments, please refer to Figure 3 , the second filter component 105 can be pulled out of the box body 101 from one end of the box body 101 along the third direction. The pulling out of the box body 101 means that the second filter component 105 is completely separated from the box body 101, so that it is convenient for the user to disassemble the second filter component 105 by hand. In this embodiment, the handle component 108 will not interfere with the pulling out action of the second filter component 105, and the two do not interfere with each other; and when the filter device 10 is placed in the object, the side where the handle component 108 is located is generally the appearance surface, and the first end of the box body 101 along the third direction is the extraction structure reserved for the second filter component 105, which will not affect the appearance of the filter device 10; in addition, when the second filter component 105 is pulled out of the box body 101 along the first end of the third direction, the second filter component 105 can be pulled out of the box body 101 more conveniently by applying force along the second end of the handle component 108 along the third direction.

[0104] For example, please refer to Figure 3 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 filtering capacity under the impact of airflow.

[0105] For example, please refer to Figure 3The box body 101 has a guide groove 101d adapted to the second support frame 1051, and the second support frame 1051 is arranged in the guide groove 101d. The guide groove 101d extends along the second direction and passes through the end surface 1032c of the box body 101 and defines a bayonet 101d1. The bayonet 101d1 is used to pull the second support frame 1051 out of the guide groove 101d, and the second filter assembly 105 is pulled out from the second end of the box body 101 along the third direction through the guide groove 101d and the bayonet 101d1.

[0106] The application scenarios of the filter device 10 in the embodiment of the present application are not limited. The embodiment of the present application is described by taking the application of the filter device 10 to the laundry processing device 1 as an example. It is understandable that the filter device 10 can also be applied to other products.

[0107] The present application embodiment provides a clothes processing device 1, please refer to Fig.11 and Fig.12 , including a cylinder assembly 11, a box body 12, a base 13 and a filtering device 10 of any of the above embodiments.

[0108] The drum assembly 11 has a laundry processing chamber 11a, an air inlet and an air outlet. The drum assembly 11 is disposed in a box 12, and the box 12 has a first port 12a.

[0109] The base 13 has an air duct 13a, which communicates with the air inlet and the air outlet to form a circulation air duct 13a with the laundry processing chamber 11a. The filter device 10 is movably arranged on the air flow path of the air duct 13a and can be pulled out of the box body 12 through the first opening 12a.

[0110] The clothing processing device 1 may be a clothes dryer, a washer-dryer, etc., and is not limited here.

[0111] Exemplarily, the principle of drying clothes in the clothes processing device 1 is as follows: the dry hot air flow in the air duct 13a enters the clothes processing chamber 11a from the downstream of the air duct 13a along the air flow direction through the air inlet. In the clothes processing chamber 11a, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs moisture in the clothes, and becomes a humid hot air flow. The humid hot air flow enters the upstream of the air duct 13a through the air outlet, and flows through the condensation dehumidification component and the heating component in turn. In the process of flowing through the condensation dehumidification component, the water vapor in the humid hot air flow is separated from the air flow due to the cooling and condenses into water droplets. The humid hot air flow is condensed and dehumidified by the condensation dehumidification component to form a low-temperature dry air flow. The low-temperature dry air flow is heated to a dry hot air flow when passing through the heating component. The dry hot air flow enters the clothes processing chamber 11a from the downstream of the air duct 13a again, and the cycle is run in this way to achieve continuous and efficient drying of clothes.

[0112] It should be noted that the low-temperature dry airflow is relative to the humid hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid hot airflow. The low temperature in the embodiment of the present application may be room temperature.

[0113] In some embodiments, the condensation and dehumidification element may be an evaporator 15 in a heat pump system, and the heating element may be a condenser 16 in a heat pump system. In other embodiments, the condensation and dehumidification element may condense and dehumidify the airflow through condensed water, and the heating element may be a resistance wire heater.

[0114] In some embodiments, please refer to Fig.11 The laundry processing device 1 includes a detergent box 14, and the filter device 10 is located above the detergent box 14. In this way, the arrangement of the filter device 10 fits the user's usage habits and improves the user's usage experience.

[0115] In some embodiments, please refer to Figure 2 and Fig.12 The air duct 13a has a docking port 13a1, and the air inlet 101b of the box body 101 is arranged on the side wall 101h (hereinafter referred to as the rear side wall 101h2) at one end of the box body 101 along the third direction, and the rear side wall 101h2 of the box body 101 is sealed and docked with the docking port 13a1 along the third direction. It should be noted that the rear side wall 101h2 of the box body 101 refers to the end of the box body 101 away from the handle assembly 108 along the third direction. It can be understood that the airflow flows to the air inlet 101b through the docking port 13a1 of the air duct 13a and enters the filter device 10 for filtering treatment. The rear side wall 101h2 of the box body 101 is sealed and docked with the docking port 13a1 along the third direction, which reduces the leakage of the airflow in the process of flowing to the air inlet 101b.

[0116] In some embodiments, please refer to Fig.12 The base 13 has a transition cavity 13b, a first installation cavity 13c and a second installation cavity 13d, the filter device 10 is arranged in the first installation cavity 13c, the clothing processing device 1 includes an evaporator 15 and a condenser 16, the evaporator 15 and the condenser 16 are arranged in the second installation cavity 13d, and the transition cavity 13b is connected to the air outlet. The transition cavity 13b is arranged on the rear side of the first installation cavity 13c, and the junction between the two defines a docking port 13a1. It can be understood that the airflow is filtered by the filter device 10 and then flows to the evaporator 15 and the condenser 16, so that the amount of hair attached to the evaporator 15 and the condenser 16 is reduced, and the heat exchange effect between the airflow and the evaporator 15 and the condenser 16 is improved.

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

[0118] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
