Description

Technical Field

[0001] The present invention belongs to the technical field of clothing treatment, and particularly relates to a lint filtering component, and also relates to a control method for a clothing treatment machine equipped with the lint filtering component. Background Art

[0002] With the progress of society and the development of technology, people's requirements for the quality of life are getting higher and higher. As a common household appliance in life, people's requirements for clothing treatment machines are also getting higher and higher. Therefore, the functions of clothing treatment machines are becoming more and more comprehensive and diverse. Among them, clothing treatment machines that can dry the washed clothes are widely popular because they can better adapt to rainy and humid weather and can shorten the drying time of clothes in the later stage.

[0003] During the drying process of clothes by a clothing treatment machine, the circulating air flow will carry the lint shed during clothing washing into the drying system. Over time, the lint will block the drying system (in an electric heating type washing and drying integrated machine, the lint will hang on the electric heater and the air duct; in a heat pump type washing and drying integrated machine, the lint will get stuck in the fins), thereby affecting the drying efficiency. To solve this problem, usually a layer (or two layers) of filters is set in the air inlet passage of the drying system to filter the lint shed from clothes. To ensure the stability of the drying system, users need to maintain the filter.

[0004] However, the air duct is generally arranged inside the clothing treatment machine. The air outlet of the drum module is arranged at the rear end, the air inlet end of the air duct extends to the rear end of the drum module and is connected to the air outlet, and the filter is arranged at the air outlet of the air duct close to the drum module. In this structure, if the user wants to take out the filter from the side of the cabinet, the user needs to pull it out a long distance in the pulling direction, and it is difficult to take out and put in the filter, which seriously affects the user experience.

[0005] Therefore, designing a drying system that can facilitate the user to disassemble and assemble the filter has become a technical problem that needs to be solved urgently by those skilled in the art.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0071] Embodiment 1

[0072] As Figures 1 to 6 shown, in an embodiment of the present invention, a lint filtering assembly 3 is introduced.

[0073] In this embodiment, the lint filtering assembly 3 is disposed in the drying system 2. Specifically, the drying system 2 is in communication with the tub module of the laundry processor, and includes an air duct 21 for air flow. The lint filtering assembly 3 is disposed on the air duct 21 and is used to filter sundries such as lint and fluff in the air flowing through the air duct 21, so as to prevent sundries such as lint and fluff from clogging the drying system 2 and ensure the drying efficiency of the drying system 2.

[0074] The lint filtering assembly 3 includes a filter screen 31 and a pulling mechanism 32 for disassembling and assembling the filter screen 31.

[0075] As Figure 1 shown, in this embodiment, the filter screen 31 is detachably installed in the air duct 21 and is used to filter fluff in the air duct 21. The pulling mechanism 32 is disposed on the side of the air duct 21 and is connected to the filter screen 31 for disassembling the filter screen 31.

[0076] When the conventional lint filtering assembly 3 disassembles the filter screen 31, it is often necessary to first pull out the pulling part 322 connected to the filter screen 31, and then continue to pull to pull out the filter screen 31 connected to the pulling part 322. That is, it is necessary to pull out the pulling part 322 by a length equal to its own length plus the length of the filter screen 31. The pulling distance is too long, which is not convenient for disassembling, assembling, and maintaining the filter screen 31, and is likely to interfere with other furniture in the user's home, seriously affecting the user experience. In this embodiment, the pulling mechanism 32 is improved to address this defect.

[0077] In this embodiment, the pulling mechanism 32 includes a shell 321 and a pulling portion 322 arranged in the shell 321. The shell 321 defines a channel for disassembly and assembly of the filter 31. The pulling portion 322 is pulled out from the end of the shell 321 away from the air duct 21 and is arranged in the shell 321. The filter 31 is slidably arranged on the pulling portion 322. One end of the filter 31 close to the pulling mechanism 32 at least partially extends to the outside of the air duct 21, and a positioning structure for limiting the relative position between the two is arranged between the pulling portion 322. In this embodiment, the pull-out mechanism 32 is used to take and place the filter 31 in the air duct 21. The filter 31 is slidably set on the pull-out portion 322, and a positioning structure for limiting the relative position of the filter 31 and the pull-out portion 322 is set between the filter 31 and the pull-out portion 322. The user can take out the filter 31 by pulling in two stages, that is, the user can first pull out the pull-out portion 322, and then pull out the filter 31 on the pull-out portion 322. This can shorten the moving length of the pull-out portion 322 when the user disassembles and maintains the filter 31, thereby improving the user's experience.

[0078] Specifically, the filter 31 is arranged at a certain angle to the extension direction of the air duct 21, and the filter 31 covers the cross section of the air duct 21 along the width direction, that is, the projection of the filter 31 covers the flow area of the air duct 21 at the installation position of the filter 31, so that the airflow passing through the air duct 21 is filtered by the filter 31. The extension direction of the filter 31 can be perpendicular to the extension direction of the air duct 21, or it can be non-perpendicular, as long as the projection of the filter 31 can cover the cross section of the air duct 21.

[0079] The filter 31 is arranged in the air duct 21 in a pullout manner from one side of the air duct 21. Specifically, the filter 31 is arranged in the air duct 21 in a pullout manner along its length direction. The user can pull out the filter 31 and take it in and put it in. The pulling mechanism 32 is arranged on the side of the air duct 21, and the pulling part 322 is connected to the filter 31, so that the filter 31 can be pulled out and put in by the pulling mechanism 32.

[0080] In this embodiment, the pull-out mechanism 32 extends in the disassembly direction of the filter 31. Specifically, a take-out opening for disassembling the filter 31 is provided on the side wall of the air duct 21, and the housing 321 is installed at the take-out opening on the air duct 21. The end of the channel of the housing 321 that is connected to the air duct 21 is arranged around the take-out opening on the air duct 21, and the channel extends in the length direction of the filter 31. The shape of the pull-out portion 322 is adapted to the shape of the channel, and the pull-out portion 322 reciprocates in the channel of the housing 321.

[0081] Preferably, in this embodiment, an annular sealing strip is provided between the housing 321 and the side wall of the air duct 21. The sealing strip surrounds the access opening of the filter screen 31 on the air duct 21 and is used to seal the position where the air duct 21 is connected to the housing 321 of the drawer part 322, so as to prevent air flow and lint from leaking out.

[0082] In some preferred embodiments, the air duct 21 is provided in a flat shape with a rectangular cross-section. The filter screen 31 extends along the width direction of the air duct 21, and the disassembly and assembly direction of the filter screen 31 is perpendicular to the extension direction of the air duct 21.

[0083] As Figure 3 and Figure 5 As shown, the drawer part 322 is in the shape of a strip plate and has a certain thickness. The shape of the drawer part 322 is adapted to the shape of the channel of the housing 321. The drawer part 322 is slidably arranged in the housing 321 from one end of the housing 321 away from the air duct 21, and a sliding pair is formed between the drawer part 322 and the housing 321. A guiding groove 322-1 extending along its length direction is provided on one side surface of the drawer part 322, and the filter screen 31 is slidably arranged in the guiding groove 322-1, and another sliding pair is formed between the filter screen 31 and the drawer part 322.

[0084] In this embodiment, the drawer part 322 has a pulled-out position and a pushed-in position relative to the housing 321. When the filter screen 31 needs to be disassembled, first pull out the drawer part 322 to the pulled-out position. At this time, at least part of the end of the filter screen 31 close to the drawer mechanism 32 extends outside the channel, that is, when the drawer part 322 moves to the pulled-out position, at least part of the end of the filter screen 31 close to the drawer mechanism 32 extends outside one end of the housing 321 away from the air duct 21. At this time, the user can pull the filter screen 31 through the end of the filter screen 31 extending outside the housing 321.

[0085] Preferably, as Figure 3 and Figure 6 As shown, in this embodiment, a first handle part 312-1 is provided at the end of the filter screen 31 close to the drawer mechanism 32. The first handle part 312-1 is annular and formed at the end of the filter screen 31 close to the drawer mechanism 32. The user can pull the filter screen 31 through the first handle part 312-1. When the drawer part 322 moves to the pulled-out position, at least the first handle part 312-1 moves outside the housing 321.

[0086] In this embodiment, the filter screen 31 is slidably disposed in the guiding groove 322-1, and the depth of the guiding groove 322-1 is greater than or equal to the thickness of the filter screen 31. Preferably, the depth of the guiding groove 322-1 is equal to the thickness of the filter screen 31, the filter screen 31 is embedded in the guiding groove 322-1, one side of the filter screen 31 close to the bottom of the guiding groove 322-1 is in contact with the bottom of the guiding groove 322-1, and the other side of the filter screen 31 away from the bottom of the guiding groove 322-1 is coplanar with the plane where the notch of the guiding groove 322-1 is located.

[0087] In this embodiment, the outer side of the groove wall of the guiding groove 322-1 is in contact with the inner wall of the channel. Preferably, the outer sides of the two groove walls of the guiding groove 322-1 are respectively in contact with the inner walls on the upper and lower sides of the channel, and the left and right sides of the pulling part 322 are in contact with the inner walls on the left and right sides of the channel.

[0088] A mutually cooperating guiding groove 3-2 and guiding rib 3-1 are provided between the inner side of the groove wall of the guiding groove 322-1 and the filter screen 31. Specifically, the guiding groove 3-2 is provided on the groove wall of the guiding groove 322-1 or the side wall of the filter screen 31 and extends along the length direction of the pulling part 322, the guiding rib 3-1 is provided on the side wall of the filter screen 31 or the groove wall of the guiding groove 322-1 and extends along the length direction of the pulling part 322, and the guiding rib 3-1 is correspondingly installed in the guiding groove 3-2 and slides along the guiding groove 3-2. The guiding groove 3-2 and the guiding rib 3-1 cooperate with each other to limit the filter screen 31 in the guiding groove 322-1 and limit the relative movement between the filter screen 31 and the pulling part 322 to sliding along the length direction of the guiding groove 322-1.

[0089] Preferably, in this embodiment, the guiding groove 3-2 is provided on one of the two groove walls of the guiding groove 322-1, the guiding rib 3-1 is provided on the other, and the corresponding guiding rib 3-1 and guiding groove 3-2 are respectively provided on the side wall of the filter screen 31.

[0090] Preferably, in this embodiment, the bottom of the guiding groove 322-1 extends along the length direction of the pulling part 322, the groove wall of the guiding groove 322-1 is perpendicular to the bottom of the guiding groove 322-1, and the depth direction of the guiding groove 3-2 is perpendicular to the length direction of the pulling part 322, that is, the depth direction of the guiding groove 3-2 is perpendicular to the groove wall of the guiding groove 322-1.

[0091] The filter screen 31 is disassembled and assembled from the side of the pulling part 322 where the guiding groove 322-1 is provided. Specifically, at least one end of the guiding groove 3-2 and / or guiding edge 3-1 on the groove wall of the guiding groove 322-1, which is far away from the air duct 21, bends away from the bottom of the guiding groove 322-1 in the direction away from the air duct 21; an installation opening 3-3 for taking and placing the filter screen 31 is provided on the end surface of the pulling part 322 that is flush with the notch of the guiding groove 322-1.

[0092] In this embodiment, the guiding groove 3-2 and the guiding edge 3-1 on the groove wall of the guiding groove 322-1 correspond to each other. The guiding edge 3-1 and the guiding groove 3-2 on the side wall of the filter screen 31 correspond to each other. The guiding edge 3-1 on the side wall of the filter screen 31 is in sliding fit with the guiding groove 3-2 on the groove wall of the guiding groove 322-1, and the guiding groove 3-2 on the side wall of the filter screen 31 is in sliding fit with the guiding edge 3-1 on the groove wall of the guiding groove 322-1. Specifically, the width direction of the filter screen 31 extends longitudinally, and the upper and lower side walls of the filter screen 31 are respectively in sliding fit with the groove wall of the guiding groove 322-1.

[0093] The filter screen 31 is made of an elastic material. When the user pulls the filter screen 31 in the direction away from the air duct 21, the filter screen 31 moves along the guiding groove 3-2 and the guiding edge 3-1 on the groove wall of the guiding groove 322-1. When the filter screen 31 moves to the position where the guiding groove 3-2 and the guiding edge 3-1 on the groove wall of the guiding groove 322-1 bend, it undergoes elastic deformation and generates corresponding bending. The installation opening 3-3 for disassembling and assembling the filter screen 31 is provided at one end of the guiding groove 3-2 and the guiding edge 3-1 on the groove wall of the guiding groove 322-1 that is far away from the air duct 21 and on the side away from the bottom of the guiding groove 322-1. The filter screen 31 is disassembled and assembled from the plane of the pulling part 322 that is coplanar with the notch of the guiding groove 322-1 through the installation opening 3-3.

[0094] Preferably, in this embodiment, the groove wall of the guiding groove 3-2 on the groove wall of the guiding groove 322-1, which is close to the bottom of the guiding groove 322-1, is smoothly connected to the side surface of the pulling part 322 on the side away from the air duct 21 of the installation opening 3-3; one end of the guiding edge 3-1 on the groove wall of the guiding groove 322-1 that is far away from the air duct 21 corresponds to the middle of the installation opening 3-3 on the guiding groove 3-2 on the groove wall of another guiding groove 322-1. To ensure that the upper and lower sides of the filter screen 31 can be disassembled and assembled synchronously.

[0095] Preferably, guiding portions with gradually decreasing thickness in a direction away from each other are provided at both ends of the guiding rib 3-1. That is, the thickness of the guiding rib 3-1 near the air duct 21 gradually decreases in the direction approaching the air duct 21, and the thickness of the guiding rib 3-1 away from the air duct 21 gradually decreases in the direction away from the air duct 21. Specifically, the sides of the guiding portion opposite to the notch of the guiding groove 322-1 and opposite to the bottom of the guiding groove 322-1 are respectively provided as arc surfaces. Preferably, the extension length of the arc surface on the side of the guiding portion opposite to the groove wall of the guiding groove 322-1 is greater than the extension length of the arc surface on the side of the guiding portion opposite to the notch of the guiding groove 322-1.

[0096] In this embodiment, the guiding groove 3-2 and the guiding rib 3-1 on the groove wall of the guiding groove 322-1 can be integrally provided as arcs curved toward the side close to the notch of the guiding groove 322-1 in a direction away from the air duct 21, or only the guiding groove 3-2 and the end of the guiding rib 3-1 on the groove wall of the guiding groove 322-1 away from the air duct 21 can be provided as arcs curved toward the side close to the notch of the guiding groove 322-1 in a direction away from the air duct 21.

[0097] Preferably, in this embodiment, the bending position of the guiding groove 3-2 and the guiding rib 3-1 on the groove wall of the guiding groove 322-1 is only set at the end away from the air duct 21, so as to ensure that after the filter screen 31 is installed on the drawing portion 322, the whole filter screen 31 remains flat, thereby reducing the stress between the filter screen 31 and the drawing portion 322, improving the service life of the filter screen 31, and at the same time, preventing the filter screen 31 from protruding from the guiding groove 322-1 and ensuring the smoothness of the drawing of the drawing portion 322.

[0098] In this embodiment, the side of the filter screen 31 opposite to the bottom of the guiding groove 322-1 abuts against and is in sliding fit with the bottom of the guiding groove 322-1. Preferably, at least the end of the bottom of the guiding groove 322-1 away from the air duct 21 is curved in a direction approaching the notch of the guiding groove 322-1 in a direction away from the air duct 21.

[0099] Preferably, the bottom of the guiding groove 322-1 is parallel to the extension direction of the guiding groove 3-2 and / or the guiding rib 3-1 on the groove wall of the guiding groove 322-1, and is smoothly connected with the side surface of the drawing portion 322 in a smooth transition. Specifically, the bottom of the guiding groove 322-1 is parallel to the extension direction of the guiding groove 3-2 and the guiding rib 3-1 on the groove wall of the guiding groove 322-1.

[0100] In this embodiment, after the filter screen 31 is installed in the guiding groove 322-1 on the pulling part 322, it is connected to the pulling part 322 through the positioning structure between the end of the filter screen 31 far from the air duct 21 and the pulling part 322, so as to avoid relative sliding between the two. Thus, during the process of pushing and pulling out the pulling part 322, the filter screen 31 is pushed into the air duct 21 or pulled out from the air duct 21 following the pulling part 322.

[0101] As Figure 3 shown, in this embodiment, at least a part of the end of the pulling part 322 close to the air duct 21 overlaps with the end of the filter screen 31 close to the pulling mechanism 32.

[0102] The positioning structure can be any detachable structure, such as a screw structure, a magnetic attraction structure, and a clamping structure. Specifically, after the filter screen 31 is installed on the pulling part 322, it can be positioned by a screw passing through the filter screen 31 and tightened on the pulling part 322, and / or, a magnetic attraction structure can be arranged between the end of the filter screen 31 far from the air duct 21 and the pulling part 322. After the filter screen 31 is installed on the pulling part 322, the magnetic attraction structures between the two attract each other to realize the positioning between the filter screen 31 and the pulling part 322, and / or, after the filter screen 31 is installed on the pulling part 322, it can be positioned by the clamping structure arranged between the end of the filter screen 31 far from the air duct 21 and the pulling part 322.

[0103] Preferably, in this embodiment, the filter screen 31 and the pulling part 322 are positioned through a clamping structure. Specifically, the clamping structure includes a buckle 312-2 arranged on the filter screen 31 and a first clamping groove 322-5 arranged on the pulling part 322 and adapted to the buckle 312-2. The buckle 312-2 is arranged at the end of the filter screen 31 close to the pulling mechanism 32 and bends towards the side close to the pulling part 322, and the first clamping groove 322-5 is arranged in the middle of the pulling part 322 or at the end of the pulling part 322 close to the air duct 21 and cooperates with the buckle 312-2.

[0104] The buckle 312-2 is arranged on the first handle part 312-1 and bends and extends towards the side close to the bottom of the guiding groove 322-1 in a direction perpendicular to the pulling part 322, and the first clamping groove 322-5 is arranged in the middle of the pushing and pulling part.

[0105] In this embodiment, the distance between the first clamping groove 322-5 at the pushing position of the pulling part 322 and the inner wall of the air duct 21 far from the pulling mechanism 32 is equal to the length of the filter screen 31.

[0106] In this embodiment, an avoidance groove 322-2 for avoiding the buckle 312-2 is provided on the bottom of the guiding groove 322-1. The avoidance groove 322-2 extends in a direction away from the air duct 21 and corresponds to the buckle 312-2. The bottom of the avoidance groove 322-2 is coplanar with the flat part of the bottom of the guiding groove 322-1. During the disassembly and assembly process of the filter screen 31, the buckle 312-2 on the filter screen 31 moves along the avoidance groove 322-2, which can improve the smoothness of the disassembly and assembly of the filter screen 31.

[0107] The first clamping groove 322-5 is provided at one end of the avoidance groove 322-2 close to the air duct 21. Specifically, the end of the filter screen 31 away from the air duct 21 corresponds to the start of the bend of the bottom of the guiding groove 322-1 in a direction away from the air duct 21 towards the notch of the guiding groove 322-1. When the user pulls the filter screen 31 to disengage the buckle 312-2 from the first clamping groove 322-5, the guiding groove 3-2 and the guiding rib 3-1 on the groove wall of the guiding groove 322-1 start to bend towards the side close to the notch of the guiding groove 322-1 in a direction away from the air duct 21, so that the buckle 312-2 can smoothly disengage from the first clamping groove 322-5 and the filter screen 31 can be smoothly pulled out.

[0108] In this embodiment, when the pulling part 322 moves to the pushing-in position, the end of the pulling part 322 close to the air duct 21 is flush with the end of the housing 321 close to the air duct 21, and at least part of the end of the pulling part 322 away from the air duct 21 extends outside the housing 321 for the user to pull the pulling part 322.

[0109] Preferably, the inner wall on the side of the first clamping groove 322-5 away from the air duct 21, at least the end close to the filter screen 31, is provided as an inclined surface that inclines towards the side away from the air duct 21 in a direction close to the filter screen 31.

[0110] Preferably, in this embodiment, a positioning device is further provided between the housing 321 and the pulling part 322. The positioning device is used to lock the pulling part 322 at the pulling-out position when the pulling part 322 moves to the pulling-out position.

[0111] Specifically, as Figure 2 and Figure 4As shown, in this embodiment, the guiding groove 322-1 is provided on the first side surface of the pulling part 322, and the positioning device is arranged between the second side surface of the pulling part 322 and the housing 321. The positioning device includes an elastic positioning arm 321-1 and a second card slot 322-4. The elastic positioning arm 321-1 is arranged on the side of the pulling part 322 away from the filter screen 31. One end of it is connected to the housing 321, and the other end is provided with a positioning bump 321-2. The elastic positioning arm 321-1 abuts against the pulling part 322 through the positioning bump 321-2. The second card slot 322-4 is arranged on the pulling part 322 on the side of the first card slot 322-5 close to the air duct 21 and is adapted to the positioning bump 321-2. During the process of pulling out the pulling part 322, the positioning bump 321-2 is snapped into the second card slot 322-4 to position the pulling part 322 at the pulled-out position.

[0112] By arranging the elastic positioning arm 321-1, the pulling part 322 can be positioned at the pulled-out position, which is convenient for the user to disassemble and assemble the filter screen 31 on the pulling part 322. At the same time, it can prevent the situation that the user pulls out the pulling part 322 by too long a length and is not convenient for installation, further improving the convenience of the user to disassemble and assemble the filter screen 31 and enhancing the user experience. By arranging the second card slot 322-4 on the side of the first card slot 322-5 close to the air duct 21, it can be ensured that when the elastic positioning arm 321-1 is snapped into the second card slot 322-4, the end of the filter screen 31 away from the air duct 21 can extend to the outside of the housing 321, facilitating the user to disassemble the filter screen 31.

[0113] Preferably, in this embodiment, the elastic positioning arm 321-1 is arranged at the end of the housing 321 away from the air duct 21 and is hidden inside the housing 321. Specifically, a groove is provided on the inner wall of the housing 321 corresponding to the second side surface of the pulling part 322. The groove includes a first wall opposite to the second side surface of the pulling part 322 and a second wall arranged at one end of the first wall close to the air duct 21 and opposite to the opening at the end of the housing 321 away from the air duct 21. The elastic positioning arm 321-1 is connected to the second wall of the groove and extends from the end of the second wall of the groove close to the pulling part 322 in the direction away from the air duct 21. The elastic positioning arm 321-1 inclines towards the side close to the pulling part 322 along the extending direction away from the air duct 21. A positioning bump 321-2 is arranged on the side of the elastic positioning arm 321-1 close to the pulling part 322. The positioning bump 321-2 is adapted to the shape of the second card slot 322-4 on the pulling part 322, and the elastic positioning arm 321-1 abuts against the pulling part 322 through the positioning bump 321-2.

[0114] Preferably, in this embodiment, the second wall of the groove is arranged as an arc protruding towards the air duct 21 in the middle. A U-shaped groove structure is formed among the first wall, the second wall and the elastic positioning arm 321-1, and a reinforcing rib extending along the first wall, the second wall and the elastic positioning arm 321-1 is arranged in the U-shaped groove structure.

[0115] Preferably, a spring piece is arranged between the first wall and the elastic positioning arm 321-1. The spring piece is clamped and positioned with the housing 321. The spring piece is U-shaped and fits with the U-shaped groove structure formed by the first wall, the second wall and the elastic positioning arm 321-1.

[0116] Preferably, the second card slot 322-4 and the first card slot 322-5 are arranged in a mutually staggered manner in the length direction of the pulling part 322, and / or the size and / or shape of the positioning convex block 321-2 are different from those of the first card slot 322-5, so as to prevent the positioning convex block 321-2 from being caught in the first card slot 322-5.

[0117] Preferably, in this embodiment, at least part of the elastic positioning arm 321-1 extends to the outside of the end of the housing 321 away from the air duct 21. Thus, the user can push the end of the elastic positioning arm 321-1 to release the locking of the pulling part 322 by the elastic positioning arm 321-1.

[0118] Preferably, in this embodiment, the inner wall on the side of the second card slot 322-4 away from the air duct 21 is provided with an inclined surface inclined towards the side away from the air duct 21 along the direction away from the filter screen 31; and / or a guiding platform 312-3 is arranged on the filter screen 31. At least part of the guiding platform 312-3 extends from the side of the second card slot 322-4 away from the air duct 21 into the second card slot 322-4. The guiding platform 312-3 is arranged as a triangle with a gradually increasing height along the direction away from the air duct 21; an avoidance opening 322-3 for the guiding platform 312-3 to slide is arranged on the pulling part 322.

[0119] Specifically, as Figure 4 shown, a guiding platform 312-3 is arranged on the filter screen 31. The guiding platform 312-3 protrudes from the side surface of the filter screen 31 close to the pulling part 322.

[0120] The protruding height of the guiding platform 312-3 gradually increases in the direction away from the air duct 21, and there is a smooth transition between one end of the guiding platform 312-3 close to the air duct 21 and the side surface of the filter screen 31. The avoidance opening 322-3 communicates with the second card slot 322-4 from the side away from the air duct 21 of the second card slot 322-4, and extends in the direction away from the air duct 21 along the length direction of the drawing part 322 from the side away from the air duct 21 of the second card slot 322-4. The avoidance opening 322-3 is used to accommodate and guide the guiding platform 312-3 on the filter screen 31 when the filter screen 31 is drawn.

[0121] When the filter screen 31 is installed on the drawing part 322, that is, when the buckle 312-2 is clamped in the first card slot 322-5, the guiding platform 312-3 is placed at the connection between the avoidance opening 322-3 and the second card slot 322-4, and at least part of the guiding platform 312-3 extends from the side away from the air duct 21 of the second card slot 322-4 into the second card slot 322-4. Thus, during the process of pushing in the drawing part 322, the guiding platform 312-3 abuts against the positioning convex block 321-2 through an inclined surface that inclines from the side close to the drawing part 322 in the direction away from the air duct 21, and the positioning convex block 321-2 is pushed out of the second card slot 322-4 through the guiding platform 312-3, so that the drawing part 322 can be smoothly pushed in.

[0122] By arranging the inner wall of the side away from the air duct 21 of the second card slot 322-4 with an inclined surface that inclines from the side away from the filter screen 31 in the direction away from the air duct 21, and / or by arranging the guiding platform 312-3 on the filter screen 31, when the user pushes the drawing part 322 in the direction close to the air duct 21, the elastic positioning arm 321-1 can be reset through the inner wall of the side away from the air duct 21 of the second card slot 322-4 and / or through the guiding platform 312-3, so that the elastic positioning arm 321-1 releases the locking of the drawing part 322, and the smoothness of the process of pushing in the drawing part 322 can be improved.

[0123] In this embodiment, the guiding platform 312-3 includes a hole section penetrating the drawing part 322 and a groove section with the notch facing the side where the filter screen 31 is located. The groove section is arranged at one end of the hole section away from the air duct 21. One end of the groove bottom of the groove section close to the air duct 21 and the groove wall on the side away from the air duct 21 of the groove section are both arranged as inclined surfaces that incline from the side away from the air duct 21 in the direction close to the filter screen 31, so as to improve the smoothness of the filter screen 31 being drawn out from the drawing part 322.

[0124] As Figure 1 shown, in this embodiment, the lint filtering component 3 further includes an induction component 33. The induction component 33 is arranged between the end of the filter screen 31 and the inner wall of the air duct 21 and is used to detect the installation position of the filter screen 31.

[0125] Specifically, the induction component 33 is arranged between the inner wall of the air duct 21 on the side far from the pulling mechanism 32 and the end of the filter screen 31. The induction component 33 can be an infrared induction module or a reed switch. By setting the induction component 33, the working reliability of the lint filtering component 3 can be improved, and the filtering effect on lint can be ensured. The induction component 33 is communicatively connected to the control unit of the clothing processor.

[0126] Preferably, in this embodiment, an installation groove 2125 for accommodating the end of the filter screen 31 is provided on the inner wall of the air duct 21. The installation groove 2125 is provided on the inner wall of the air duct 21 on the side far from the pulling mechanism 32. When the filter screen 31 is inserted into the air duct 21, the end of the filter screen 31 far from the pulling part 322 is inserted into the installation groove 2125 to ensure the installation stability and working reliability of the filter screen 31.

[0127] The induction component 33 is arranged between the bottom of the installation groove 2125 and the end of the filter screen 31. The maximum detection distance of the induction component 33 is less than or equal to the depth of the installation groove 2125. Thus, it can ensure that the sealing performance and normal operation can be guaranteed even in the fuzzy recognition area recognized by the induction component 33, further improving the user experience.

[0128] In some specific embodiments, the induction component 33 is a reed switch and a magnet that cooperate with each other. The reed switch is arranged on the bottom of the installation groove 2125, and the magnet is arranged on the end of the filter screen 31 far from the pulling mechanism 32. The maximum detection distance of the reed switch is less than or equal to the depth of the installation groove 2125. When the reed switch detects the magnet, it indicates that at least part of the end of the filter screen 31 is inserted into the installation groove 2125. At this time, it can ensure that the air flow flowing through the air duct 21 can be filtered by the filter screen 31.

[0129] Specifically, in this embodiment, the magnet is embedded in the end face of the end of the filter screen 31 far from the pulling part 322.

[0130] When the reed switch detects the position of the magnet, as the magnet approaches the reed switch, the reed switch has a transition recognition area with fuzzy recognition and an area that can be clearly recognized. When the reed switch can clearly recognize the magnet, it is determined that the filter screen 31 is in the pushed-in position, and the two reed pieces of the reed switch are attracted. When the magnet stays in the transition recognition area of the reed switch, the two reed pieces of the reed switch may be determined to be attracted, may not be attracted, or may fluctuate between attraction and disconnection.

[0131] In this embodiment, the setting of the installation groove 2125 can ensure that when the reed switch initially recognizes the magnet, the filter screen 31 can stably play its role. Even if the reed switch is subsequently determined to fluctuate between attraction and disconnection, the filter screen 31 can still stably play its filtering role. At this time, it is determined that the drying program can proceed smoothly.

[0132] In this embodiment, the reed switch can also be replaced by an infrared detection module, and the infrared detection module accurately detects the distance between one end of the filter screen 31 away from the pulling mechanism 32 and the bottom of the installation groove 2125.

[0133] In this embodiment, a control method for a laundry processor is also provided. The laundry processor is provided with the above-mentioned lint filtering assembly 3. The control method includes:

[0134] When starting the drying function, obtain the position of the filter screen 31;

[0135] If the filter screen 31 is in the pushed-in position, execute the drying program;

[0136] If the distance between the filter screen 31 and the pushed-in position is less than or equal to a preset value, execute the drying program and send out a first alarm message;

[0137] If the distance between the filter screen 31 and the pushed-in position is greater than the preset value, stop running and send out a second alarm message.

[0138] In this embodiment, the first alarm message and the second alarm message can be a prompt tone, and / or a light, and / or a push message.

[0139] Preferably, in this embodiment, the first alarm message and the second alarm message are different.

[0140] In this embodiment, when the distance between the filter screen 31 and the bottom of the installation groove 2125 is less than or equal to a first value, it is defined that the filter screen 31 is in the pushed-in position. When the filter screen 31 is in the pushed-in position, the laundry processor operates normally; when the distance between the filter screen 31 and the bottom of the installation groove 2125 is greater than the first value and less than or equal to a second value, it is defined that the distance between the filter screen 31 and the pushed-in position is less than or equal to the preset value. At this time, the laundry processor executes the drying program and sends out a first alarm message; when the distance between the filter screen 31 and the bottom of the installation groove 2125 is greater than the second value, it is defined that the distance between the filter screen 31 and the pushed-in position is greater than the preset value. At this time, the laundry processor stops running and sends out a second alarm message.

[0141] In this embodiment, the second value is less than or equal to the depth of the installation groove 2125. The preset value is the difference between the second value and the first value.

[0142] In this embodiment, when the sensing component 33 is a reed switch, the first value is the area that the reed switch can clearly identify, and the preset value is the transition identification area of the reed switch.
