Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to an inner drum assembly, an outer drum assembly, clothing processing equipment and a control method. Background Art

[0002] Clothes processing equipment produces dander when drying clothes, so general clothes processing equipment has a drying filter.

[0003] Filters are divided into manual cleaning filters and automatic cleaning filters. Because manual cleaning is troublesome and affects the user experience, high-end models generally use automatic cleaning filters.

[0004] Generally, the automatic cleaning filter is fixed in the air duct near the outer cylinder, and the filter is removed by spraying water. This method can remove dander to a certain extent but cannot completely remove it. After a long period of operation, a small amount of dander that cannot be washed away will be repeatedly sprayed, soaked and dried, and will become stuck on the filter, affecting the drying cycle air volume, and thus affecting the drying time and effect.

[0005] In addition, a layer of water film will be formed on the surface of the filter after flushing with water. When the water film is not broken in the early stage of drying, the system circulating air volume is small, which affects the drying rate. Summary of the Invention

[0006] In order to overcome the problem in the related art that after long-term operation of clothing processing equipment, lint will be caked on the filter screen, affecting the drying time and drying effect, the embodiment of the present invention proposes an inner drum assembly, an outer drum assembly, a clothing processing equipment and a control method, which realizes the opening and closing of the filter screen by the force of the inner drum rotation. During drying, the filter screen is opened and attached to the side wall of the inner drum to filter lint. During washing, the filter screen is closed and separated from the side wall of the inner drum. The filter screen is soaked in washing water to dissolve the lint, and the forward and reverse oscillation of the inner drum is used to remove the lint attached to the surface of the filter screen. In addition, the dehydration process breaks the water film on the surface of the filter screen, completely solving the problem of incomplete lint removal and the water film reducing the air volume in the early stage of drying.

[0007] In a first aspect, an embodiment of the present invention provides an inner drum assembly for use in a clothes processing device. The inner drum assembly includes an inner drum and a filter module, wherein:

[0008] The outer wall of the inner cylinder is provided with a plurality of water-permeable hole groups communicating with the inner cylinder and the outer cylinder. The inner cylinder includes a water-permeable hole area with water-permeable hole groups and a non-water-permeable hole area between two adjacent water-permeable hole groups.

[0009] The filter module is arranged on the outer peripheral wall of the inner cylinder, and can be driven to be arranged in the water permeable hole area, and can also be driven to move away from the water permeable hole area to the non-water permeable hole area.

[0010] In the above technical solution, a track is provided on the inner cylinder;

[0011] The filter module is provided with a moving part and a limiting component;

[0012] The moving part is used to cooperate with the track;

[0014] The track is provided with a first limit position corresponding to the filter module cover being provided in the water permeable hole area and a second limit position corresponding to the filter module being moved from the water permeable hole area to the non-water permeable hole area; the moving part moves between the first limit position and the second limit position;

[0015] The limiting assembly is designed as follows: the movable part can move to the first limiting position under the rotation of the inner cylinder and the filter module is pressed against the water permeable hole area by the force of the limiting assembly; it can also move to the second limiting position by overcoming the force of the limiting assembly under the rotation of the inner cylinder.

One movable portion is movably arranged in the track of the track disk on the front side of the inner cylinder, and the other movable portion is movably arranged in the track of the track disk on the rear side of the inner cylinder. When the movable portion moves to the starting end of the track, the filter screen adheres to the outer wall of the inner cylinder to cover the water permeable hole group. When the movable portion moves to the ending end of the track, the filter screen separates from the outer wall of the inner cylinder to eliminate the coverage of the water permeable hole group.

[0020] When the inner cylinder rotates clockwise, the moving part can move from the side of the track starting end to the side of the track ending end to separate the filter screen from the outer wall of the inner cylinder. When the inner cylinder rotates counterclockwise, the moving part can move from the side of the track ending end to the side of the track starting end to fit the filter screen to the outer wall of the inner cylinder.

[0086] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0087] The existing clothing processing equipment currently has the problem that lint will stick to the filter after long-term operation, affecting the drying time and drying effect. The embodiment of the present invention proposes an inner drum assembly, an outer drum assembly, a clothing processing equipment and a control method, which realizes the opening and closing of the filter by the force of the inner drum rotation. During drying, the filter is opened and attached to the side wall of the inner drum to filter lint. During washing, the filter is closed and separated from the side wall of the inner drum. The filter is soaked in washing water to dissolve the lint, and the forward and reverse oscillation of the inner drum is used to remove the lint attached to the surface of the filter. In addition, the dehydration process breaks the water film on the surface of the filter, completely solving the problem of incomplete lint removal and the water film reducing the air volume in the early stage of drying.

[0088] The following is combined with Figure 1 -Attached Figure 10 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0089] Example

[0090] like Figures 1-9 As shown, in a first aspect of this embodiment, an inner drum assembly is provided for use in a clothes processing device. The inner drum assembly includes an inner drum 1 and a filter module, wherein:

[0091] The inner barrel assembly includes an inner barrel 1 and a filter module, wherein:

[0092] The inner tube 1 has an inner tube outer tube wall 1c, on which are distributed a plurality of water-permeable hole groups 11 connecting the inner tube interior and the inner tube exterior. The inner tube 1 includes a water-permeable hole area having the water-permeable hole groups 11 and a non-water-permeable hole area between two adjacent water-permeable hole groups.

[0093] The filter module is arranged on the inner and outer cylinder walls 1c. It can be driven to be attached to the water permeable hole area, or driven to move from the water permeable hole area to the non-water permeable hole area and be arranged at a distance from the non-water permeable hole area.

[0094] In the embodiment of the present invention, a filter module is provided on the inner and outer cylinder walls 1c, and the filter module can be switched between the water permeable hole area and the non-water permeable hole area. The filter module cover can be set in the water permeable hole area during drying to filter the hair debris of the clothes during drying. The filter module can also be moved to the non-water permeable hole area and separated from the inner and outer cylinder walls 1c during washing. At this time, the filter module can be soaked in washing water to dissolve the hair debris on the filter module.

[0095] Specifically, the inner cylinder 1 is provided with a track 21;

[0096] The filter module is provided with a moving portion 32 and a limit assembly;

[0097] The moving portion 32 is used to cooperate with the track 21;

[0098] The track 21 is designed so that the moving portion 32 of the filter module can move along the track 21 when the inner drum 1 rotates. The moving direction of the moving portion 32 is different when the inner drum 1 rotates in different directions, and the moving position of the moving portion 32 is different when the inner drum 1 rotates at different speeds.

[0099] The track 21 is provided with a first limit position corresponding to the filter module cover being provided in the water permeable hole area and a second limit position corresponding to the filter module being moved from the water permeable hole area to the non-water permeable hole area; the moving portion moves between the first limit position and the second limit position;

[0100] The limiting assembly is designed as follows: the moving part 32 can move to the first limiting position under the rotation of the inner cylinder 1 and the filter module is pressed against the water permeable hole area by the force of the limiting assembly; it can also move to the second limiting position under the rotation of the inner cylinder 1, overcoming the force of the limiting assembly and being set at a distance from the non-water permeable hole area.

[0101] In this embodiment, the rotational properties of the inner drum 1 enable the filter module to switch between the first and second limit positions, eliminating the need for manual adjustment of the filter module's position. Furthermore, the inner drum's forward and reverse rotations can also oscillate to remove debris adhering to the filter module's surface. Furthermore, the dehydration process breaks down the water film on the filter module's surface, completely resolving the issues of incomplete debris removal and reduced airflow during the initial drying phase.

[0102] Further, such as Figure 1 As shown, the inner cylinder 1 has an inner cylinder front side 1a and an inner cylinder rear side 1b opposite to each other, and an inner cylinder outer cylinder wall 1c between the inner cylinder front side 1a and the inner cylinder rear side 1b;

[0103] The inner barrel assembly also includes:

[0104] Track plates 2 are provided on the front side 1a and the rear side 1b of the inner cylinder. Both track plates 2 are provided with track structures. The two track structures are symmetrical in the axial direction of the inner cylinder 1. The track structures include tracks 21 arranged along the circumferential direction of the track plates 2. The tracks 21 include a track starting end 211 close to the axis of the inner cylinder 1 and a track ending end 212 away from the axis of the inner cylinder 1. The position corresponding to the track starting end is the first limit position mentioned above, and the position corresponding to the track ending end is the second limit position mentioned above.

[0105] The filter module includes a filter screen 31 provided on the outer wall 1c of the inner cylinder and located between the two track discs 2. The filter module also includes a movable portion 32 provided at both ends of the length direction of the filter screen 31. The two movable portions 32 are symmetrically arranged in the axial direction of the inner cylinder 1. One movable portion 32 is movably provided in the track 21 of the track disc 2 on the front side 1a of the inner cylinder, and the other movable portion 32 is movably provided in the track 21 of the track disc 2 on the rear side 1b of the inner cylinder. When the movable portion 32 moves to the track starting end 211, the filter screen 31 is attached to the outer wall 1c of the inner cylinder to cover the water permeable hole group 11. At this time, the filter screen 3 1 is in the open state, and when the moving part 32 moves to the track end 212, the filter screen 31 is separated from the inner and outer cylinder walls 1c to eliminate the coverage of the water permeable hole group 11. At this time, the filter screen 31 is in the closed state. {It is worth noting that the filter screen 31 in the embodiment of the present invention is in the open state, which means that the filter screen is attached to the outer wall surface of the inner cylinder. At this time, the filter screen plays a filtering role on the airflow passing through the water permeable hole group, while the filter screen 31 is in the closed state, which means that the filter screen is separated from the outer wall surface of the inner cylinder. At this time, the filter screen does not play a filtering role on the airflow passing through the water permeable hole group, or the filtering role is poor at this time};

[0106] Specifically, when the inner cylinder 1 rotates clockwise, under the action of centrifugal force, the moving portion 32 can move from the side of the track starting end 211 to the side of the track ending end 212, so that the filter screen 31 and the inner cylinder outer cylinder wall 1c are separated. When the inner cylinder 1 rotates counterclockwise, under the action of centrifugal force, the moving portion 32 can move from the side of the track ending end 212 to the side of the track starting end 211, so that the filter screen 31 and the inner cylinder outer cylinder wall 1c are fitted together.

[0107] It is worth noting that the clockwise and counterclockwise directions mentioned in the embodiments of the present invention are merely relative directions. In some alternative embodiments, when the inner cylinder rotates counterclockwise, the movable portion 32 may move from the track starting end 211 to the track ending end 212, and when the inner cylinder rotates clockwise, the movable portion 32 may move from the track ending end 212 to the track starting end 211. For ease of description of the solution in this embodiment, in this embodiment, when the inner cylinder rotates clockwise, the movable portion 32 moves from the track starting end 211 to the track ending end 212, and when the inner cylinder rotates counterclockwise, the movable portion 32 moves from the track ending end 212 to the track starting end 211.

[0108] Therefore, in this embodiment, by movably positioning the filter 31 between the two track plates 2 and combining it with the washing characteristics of the laundry processing device, the centrifugal force of the rotating inner drum of the laundry processing device can be used to open and close the filter. Specifically, during drying, the filter 31 can be opened and attached to the outer wall of the inner drum to filter out lint. During washing, the filter 31 can be closed and separated from the inner and outer walls. Wash water can be used to soak the filter to dissolve lint, and the forward and reverse rotation of the inner drum can be used to remove lint adhering to the filter surface. Furthermore, the dehydration process breaks down the water film on the filter surface, completely resolving the problems of incomplete lint removal and reduced air volume during the early stages of drying due to the water film.

[0109] Further, such as Figure 1-Figure 7 As shown, the track plate 2 is provided with a plurality of tracks 21, which are evenly distributed in the circumferential direction of the track plate 2. The movable portion 32 includes a first movable portion 321 and a second movable portion 322 distributed on both sides of the filter screen 31 in the width direction. The first movable portion 321 and the second movable portion 322 are both capable of moving in the track 211. The track 21 where the first movable portion 321 is located and the track 21 where the second movable portion 322 is located are adjacent in the circumferential direction of the track plate 2.

[0110] The first moving part 321 and the second moving part 322 on the two adjacent rails 21 are designed as follows: when the first moving part 321 is at the rail starting end 211 of one of the rails 21, the second moving part 322 is at the rail starting end 211 of the other barrel rail 21; when the first moving part 321 is at the rail ending end 212 of one of the rails 21, the second moving part 322 is at the rail ending end 212 of the other rail 21.

[0111] In the embodiment of the present invention, a moving part {a first moving part 321 and a second moving part 322} is provided at both ends of the filter screen 31 in the width direction, and the two moving parts in the width direction are respectively provided on two adjacent tracks 21 on the track plate 2. In this way, when the moving part moves to the starting end position of the track, the filter screen 31 can be completely attached to the inner cylinder and outer cylinder walls 1c, so that the filter screen 31 is fully opened. When the moving part moves to the ending end of the track, the filter screen 31 can be completely separated from the inner cylinder and outer cylinder walls 1c, so that the filter screen 31 is completely closed. Therefore, when the filter screen 31 is opened, the filtering effect of the filter screen 31 is improved, and when the filter screen 31 is closed, the cleaning effect of the filter screen 31 is improved.

[0112] like Figure 2-Figure 7 As shown, of two tracks 21 adjacent in the circumferential direction of the track disc 2 , a track starting end 211 of one track 21 and a track ending end 212 of an adjacent track 21 are opposite to each other in the radial direction of the track disc 2 and are spaced apart.

[0113] In the embodiment of the present invention, by arranging two adjacent tracks 21 in the circumferential direction of the track disk 2 according to the above-mentioned structure {that is, the track starting end 211 of one track 21 and the track ending end 212 of the adjacent track 21 are opposite to each other and spaced apart in the radial direction of the track disk 2}, when the first movable portion 321 is at the track starting end 211 position of one of the tracks 21, the second movable portion 322 can be at the track starting end 211 position of the other tube track 21; and when the first movable portion 321 is at the track ending end 212 position of one of the tracks 21, the second movable portion 322 can be at the track ending end 212 position of the other track 21.

[0114] Further, such as Figure 3 As shown, the filtering module also includes:

[0115] The connecting rod unit 33 is rotatably mounted on the inner cylinder shaft 12 at the rear side of the inner cylinder and is connected to the moving portion 32 located on the track plate 2 at the rear side of the inner cylinder 1;

[0116] When the inner cylinder 1 driven by the inner cylinder shaft 12 rotates, the moving portion 32 can move on the track 21 and drive the connecting rod unit 33 to rotate relative to the inner cylinder shaft 12 .

[0117] That is, the filter screen 31 in the embodiment of the present invention moves relative to the inner drum 1 , which is driven by the connecting rod unit 33 .

[0118] Specifically, such as Figure 3-Figure 7 As shown, the connecting rod unit 33 includes two telescopic rod units 331 of the same structure, wherein one telescopic rod unit 33 is connected to the first moving portion 321 of the rear side 1b of the inner cylinder, and the other telescopic rod unit 33 is connected to the second moving portion 322 of the rear side 1b of the inner cylinder;

[0119] like Figure 8 As shown, the telescopic rod unit 331 includes:

[0120] A spring mounting housing 3311 is provided along the radial direction of the inner cylinder 1, wherein the spring mounting housing 3311 is limited in the radial direction of the inner cylinder 1;

[0121] and a telescopic rod 3312 capable of radial displacement along the inner tube 1, with a portion of the telescopic rod 3312 slidably disposed within the spring mounting housing 3311 and another portion located outside the spring mounting housing 3311 for connection with the corresponding moving portion 32;

[0122] and a telescopic rod spring 3313 connected to the telescopic rod 3312 for limiting radial displacement of the telescopic rod 3312;

[0123] When the filter screen 31 and the side circumferential wall 1c of the inner tube are separated, the telescopic rod 3312 moves radially outward of the inner tube 1, and the telescopic rod spring 3313 is in a stretched state. When the filter screen 31 and the side circumferential wall 1c of the inner tube are attached, the telescopic rod 3312 moves radially inward of the inner tube 1, and the telescopic rod spring 3313 is in a contracted state.

[0124] In the embodiment of the present invention, a telescopic rod unit 331 is provided to connect with the moving part. On the one hand, the moving part can be moved relative to the inner cylinder 1. On the other hand, the moving part can be located at different radial positions of the inner cylinder during movement, thereby realizing the opening and closing of the filter screen 31.

[0125] In any of the above embodiments, Figure 1-Figure 4 As shown, the connecting rod unit 33 also includes:

[0126] The connecting rod includes a first connecting rod 332 rotatably mounted on the inner cylinder shaft 12 and extending radially along the inner cylinder 1 , and a second connecting rod 333 connected to an extended end of the first connecting rod 332 and connecting the two telescopic rod units 331 ;

[0127] The inner cylinder assembly further includes a rotating component 4 disposed on the inner cylinder shaft 12 and capable of rotating synchronously with the inner cylinder 1. The rotating component 4 has a connecting rod mounting groove capable of accommodating a portion of the first connecting rod 332. The connecting rod mounting groove includes a first mounting groove 41 and a second mounting groove 42 distributed in the circumferential direction of the inner cylinder 1. A limiting structure 43 is provided between the first mounting groove 41 and the second mounting groove 42. The limiting structure is used to limit the first connecting rod 332 in the first mounting groove 41 or the second mounting groove 42.

[0128] When the inner cylinder 1 rotates at an acceleration a, the first connecting rod 332 can break through the restriction of the limiting structure and move from the first mounting groove 41 to the second mounting groove 42 or from the second mounting groove 42 to the first mounting groove 41 .

[0129] That is, in the embodiment of the present invention, the filter 31 is opened and closed by controlling the acceleration a of the inner drum 1 in different rotation directions.

[0130] It is worth noting that the acceleration a is greater than the normal forward and reverse acceleration of the inner cylinder 1. The force generated by the acceleration can enable the first connecting rod 332 to break through the restriction of the limiting structure 43 to complete the switching of the first connecting rod 332 between the first installation groove 41 and the second installation groove 42.

[0131] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown, the rotating component 4 includes:

[0132] A rotating disk 4a is provided at the center of the rear side 1b of the inner cylinder and rotates synchronously with the inner cylinder 1. The rotating disk 4a includes an inner disk surface close to the rear side 1b of the inner cylinder and an outer disk surface away from the rear side 1b of the inner cylinder;

[0133] The cam 4a is a kind of cam which is fixed on the cam 4b and is used for the rotation of the cam 4b. The cam 4a is a kind of cam which is fixed on the cam 4b and is used for the rotation of the cam 4b.

[0134] The first connecting rod 332 rotatably arranged on the inner cylinder shaft 12 can switch from the first state to the second state when the inner cylinder 1 rotates clockwise at an acceleration a, and can switch from the second state to the first state when the inner cylinder 1 rotates counterclockwise at an acceleration a.

[0135] It is worth noting that the contact surfaces of the rotating disk 4a and the limit disk 4b have a surface treatment that increases friction. When the two are elastically connected, the rotating disk 4a drives the limit disk 4b to rotate by friction, and the first connecting rod 332 is located in the first mounting groove 41 or the second mounting groove 42 to drive the filter screen 31 to rotate around the inner cylinder axis 12 along with the tripod 13 and the inner cylinder 1.

[0136] Further, such as Figure 1 As shown, the inner barrel assembly also includes:

[0137] A rear cylinder spring fixing ring 5 is provided on the outer disk side of the limiting disk 4b and rotates synchronously with the inner cylinder 1. A rear cylinder spring 6 is provided inside the rear cylinder spring fixing ring 5. The rear cylinder spring 6 elastically contacts the outer disk surface of the limiting disk 4b, so that the inner disk surface of the limiting disk 4b elastically contacts the outer disk surface of the rotating disk 4a.

[0138] And the spring fixing ring shell 7, the rear tube spring fixing ring 5 is fixed on the spring fixing ring shell 7, and the spring fixing ring shell 7 is fixed on the tripod 13 of the inner tube 1.

[0139] The elastic contact effect between the limiting disk 4b and the rotating disk 4a is achieved by providing a rear cylinder spring 6 that is elastically contacted with the limiting disk 4b.

[0140] In any of the above embodiments, Figure 5-Figure 7 As shown, the filter module further includes rollers 33 symmetrically fixed on both sides of the filter screen 31 in the width direction, and the rollers 33 extend along the length direction of the filter screen 31;

[0141] The first moving portion 321 includes a first pulley rotatably mounted on the end of one of the rollers, and the second moving portion 322 includes a second pulley rotatably mounted on the end of the other roller.

[0142] In any of the above embodiments, Figure 1-Figure 4 As shown, multiple groups of filter modules are provided, and the multiple groups of filter modules are evenly distributed in the circumferential direction of the inner tube 1;

[0143] The side wall of the inner cylinder 1 is provided with a plurality of water-permeable hole groups along the circumference of the inner cylinder 1. When the inner cylinder 1 rotates, each group of filter modules can open or close a corresponding water-permeable hole group 11;

[0144] Each water permeable hole group 11 includes a plurality of water permeable holes.

[0145] In order to more clearly understand the working principle of the inner cylinder assembly in this embodiment, Figures 1-9 For further explanation:

[0146] In this embodiment, the filter 31 is arranged on the side wall {i.e., the outer wall of the inner tube} 1c of the inner tube 1. There are water-permeable holes on the wall of the inner tube 1 corresponding to the open position of the filter 31, which are used for drying ventilation and washing water drainage. There are no holes on the wall of the inner tube corresponding to the closed position of the filter to prevent part of the circulating air from not being filtered by the filter 31 during drying.

[0147] The filter 31 is secured at both ends in the width direction by rollers 33, with pulleys mounted on the front and rear sides of the rollers 33. Track plates 2 are installed on both the front 1a and rear 1b sides of the inner cylinder. The track plates 2 on the front 1a side of the inner cylinder contain six tracks 21 for the pulleys to slide on, while the track plates 2 on the rear 1b side of the inner cylinder contain six tracks 21 for the pulleys to slide on. The pulleys roll within the tracks 21, thereby switching the position of the filter 31 and opening and closing it.

[0148] The roller 33 is connected to the telescopic rod unit 331, which includes a spring mounting housing 3311, a telescopic rod 3312, and a telescopic rod spring 3313. When the filter 31 is in the open position (the filter 31 is in contact with the outer wall of the inner cylinder), the telescopic rod spring 3313 is in a stretched state, ensuring that the roller 33 on the filter 31 is tightly attached to the outer wall of the inner cylinder 1. When the filter 31 is in the closed position (the filter 31 is separated from the outer wall of the inner cylinder), the telescopic rod spring 3313 is in a compressed state, and the roller slides to the end of the track.

[0149] The two telescopic rod units 331 are fixed by a connecting rod, which includes a first connecting rod 332 and a second connecting rod 333 connected to each other. The second connecting rod 333 connects the two telescopic rod units 331, and the first connecting rod 332 is rotatably arranged around the inner cylinder shaft 12. The filter 31 is opened and closed by rotating the first connecting rod 332.

[0150] The rotating disk 4a is fixed to the tripod 13 and rotates with the tripod 13. A limit plate 4b contacts the outer surface of the rotating disk 4a. The limit plate 4b defines a connecting rod mounting slot. The connecting rod mounting slot includes a first mounting slot 41 and a second mounting slot 42 separated by a limit structure 43. The root of the first connecting rod 332 can be inserted into the first mounting slot 41 or the second mounting slot 42.

[0151] like Figure 9 As shown, the left side of the first mounting groove 41 is an axial vertical surface, and the right side of the first mounting groove 41 is a curved transition surface. When the first connecting rod 332 is placed in the first mounting groove 41, the first connecting rod 332 can only rotate to the right relative to the limit plate 4b, but cannot rotate to the left. There are three such first mounting grooves 41, corresponding to the roots of the three first connecting rods 332 in the open position of the filter 31. Correspondingly, the left side of the second mounting groove is a curved transition surface, and the right side of the second mounting groove 42 is an axial vertical surface. When the first connecting rod 332 is placed in the second mounting groove 42, the first connecting rod 332 can only rotate to the left relative to the limit plate 4b, but cannot rotate to the right. There are three such second mounting grooves 42, corresponding to the roots of the three first connecting rods 332 in the closed position of the filter 31.

[0152] The contact surfaces of the rotating disk 4a and the limiting disk 4b have a surface treatment that increases friction. Behind the limiting disk 4b are multiple rear-tube spring retaining rings 5, each containing a rear-tube spring 6. The bottoms of the spring retaining rings 5 ​​are fixed to the spring retaining ring housing 7, which is in turn fixed to the tripod 13. When the filter 31 is in the open position, the limiting disk 4b, driven by the rear-tube spring 6, makes close contact with the rotating disk 4a. The rotating disk 4a drives the limiting disk 4b to rotate due to friction. The first connecting rod 332, located in the first mounting slot 41, drives the filter 31 to rotate along with the tripod 13 and the inner cylinder 1 around the inner cylinder axis 12.

[0153] To switch to the filter 31 closed position, the counterclockwise rotation acceleration of the inner drum 1 is increased. Under the action of inertia, the first connecting rod 332 rotates clockwise relative to the limit plate 4b, passing through the transition surface, gradually compressing the rear drum spring 6, causing the first connecting rod 332 to pass over the transition surface and eventually move into the second mounting slot 42 corresponding to the filter closed position. The rear drum spring 6 returns to its original state, and the first connecting rod 332 is unable to continue rotating clockwise due to the vertical surface to the right of the second mounting slot 42, thus ending its rotation. The rightward rotation of the first connecting rod 332 drives the pulley within the track 21 of the track plate 2, compressing the telescopic rod spring 3313 and extending the pulley radially outward, ultimately moving to the filter closed position. Conversely, to switch the filter 31 to the open position, the counterclockwise rotation acceleration of the inner drum 1 is simply increased, and the process is similar to the above.

[0154] When the clothes processing device having the inner drum assembly performs a drying process, the filter 31 is opened, and hair debris adheres to the filter 31 when passing through the filter.

[0155] When a laundry treatment device with the aforementioned inner drum assembly is executing a wash cycle, the filter is in the closed state. Filter 31 is closed and spaced a certain distance from the outer wall of inner drum 1. After the wash cycle is complete, filter 31 is submerged in the wash water, allowing hair debris to dissolve in the water and drain from the gap between filter 31 and the outer wall of inner drum 1. During washing, inner drum 1 rotates forward and backward, and any hair debris that is not dissolved and carried away is thrown off and carried away by the forward and reverse rotation of the inner drum. During high-speed dehydration, the water film attached to filter 31 breaks apart under the action of centrifugal force, thereby achieving the purpose of completely removing hair debris and breaking up the water film.

[0156] Specifically, the system first checks whether the filter needs to be turned on and its current on / off state. If the filter needs to be switched on, the drum rotates counterclockwise at acceleration a for b seconds. If the filter needs to be switched off, the drum rotates clockwise at acceleration a for b seconds. Acceleration a is greater than the normal forward and reverse acceleration of the drum. The force generated by this acceleration can push the rear cylinder spring open, completing the rotation of the first connecting rod. The value can range from 50 rpm / s to 100 rpm / s. Time b is the time required for the connecting rod to complete the switching rotation.

[0157] In summary, the inner drum assembly provided in the embodiment of the present invention adopts the filter screen 31 of the above-mentioned structure, which soaks and dissolves hair debris during the washing process, completely removes hair debris on the filter screen 31 through the vibration of the inner drum 1, and uses the centrifugal force during dehydration to break the water film, completely solving the problem of hair debris compaction due to long-term operation of the filter screen 31 and the water film in the early stage of drying affecting the drying air volume.
