Description

Lint filtering assembly, drying system, clothes processing machine and control method Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a lint filtering component, a drying system, a clothing processing machine, and a control method and drying system for a clothing processing machine. Background Art

[0002] With the advancement of society and technology, people's demands for a higher quality of life are growing. As a common household appliance, clothes processors are also becoming more demanding. Consequently, the functions of clothes processors are becoming increasingly comprehensive and diverse. Among them, clothes processors that can dry washed clothes are particularly popular because they are well-suited to rainy and humid weather and can shorten the drying time of clothes.

[0003] When a clothes washer dries clothes, the circulating airflow carries lint from washing into the drying system. Over time, this lint can clog the drying system (in electrically heated washer-dryers, lint can get stuck in the heater and air duct; in heat pump washer-dryers, lint can get stuck in the fins), affecting drying efficiency. To address this issue, a single (or double) filter is typically installed in the drying system's air inlet duct to filter out lint. To ensure the drying system's stable operation, the filter must be maintained by the user.

[0004] However, the air duct is typically located inside the laundry machine, with the drum module's air outlet located at the rear end. The air inlet of the duct extends to the rear end of the drum module and connects to the air outlet. The filter is located near the drum module's air outlet. With this structure, removing the filter from the side of the machine requires pulling it a long distance in the correct direction, making it difficult to remove and place the filter, severely impacting the user experience.

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

[0006] If lint is only filtered through the filter, it will accumulate on the filter. In order to ensure the stability of the drying system, the user needs to clean the filter after the clothes processor uses the drying function several times. The high cleaning frequency seriously affects the user experience.

[0007] Therefore, designing a drying system that can ensure high filtering effect and reduce the frequency of filter cleaning by users has become a technical problem that needs to be solved urgently by those skilled in the art.

[0008] To facilitate user cleaning of the filter, some models feature a lint filter assembly that pulls out from the front panel of the machine, with the front end of the pull-out section positioned on the front panel. While this improves user convenience in removing and cleaning the filter, the pull-out section creates protrusions and / or grooves on the front panel to facilitate pulling the section out, making the panel of the machine unsmooth and affecting the overall appearance of the machine.

[0009] Therefore, designing a clothes processing machine that is convenient for users to remove the filter for cleaning and can also ensure the appearance of the clothes has become a technical problem that needs to be solved urgently by those skilled in the art.

[0010] In view of this, the present invention is proposed. Summary of the Invention

[0011] One object of the present invention is to provide a drying system, which arranges the air duct above the drum module, arranges the compressor in the lower middle part of the drum module and is spaced apart from the vertical axial bisector of the drum module, that is, arranges the compressor on the lower side of the drum module, thereby making full use of the space on both sides of the lower side of the drum module, and laying out the drying system to make the layout more compact, thereby solving the problems of existing clothing processing equipment with drying function, such as poor compactness of internal structure layout and large size of the whole machine.

[0012] Another object of the present invention is to provide a drying system, in which a sedimentation section and a filter are provided on the air duct, so that the hot and humid drying air flow blown into the air duct first flows through the sedimentation section, and contacts and exchanges heat with the condensed water in the sedimentation section. The condensed water condenses the hot and humid drying air flow, and the lint and water droplets carried in the drying air flow condense and settle, thereby achieving a primary filtration of the drying air flow. The drying air flow then flows through the filter for a secondary filtration, which can ensure the filtering effect of the lint in the drying air flow. Moreover, the filter downstream of the sedimentation section only needs to filter the residual lint in the drying air flow, which solves the problem that the filter of the existing drying system needs to be cleaned frequently.

[0013] Another object of the present invention is to provide a clothes processing machine, which can improve the convenience of users in cleaning and disassembling the filter by setting a pull-out part of the pull-out mechanism to be pulled out from the panel on the front side of the box. By setting the buckle part to be opened in a push-open and flip-over manner, the buckle part can be hidden when the filter is not being pulled out. There is no need to set a protrusion or groove for facilitating the pulling out of the pull-out part on the front end of the pull-out part and the panel around the front end of the pull-out part, which can ensure the integrity and aesthetics of the panel. When the filter needs to be pulled out, the buckle part is pushed open to facilitate user operation, thereby solving the problems of inconvenient filter disassembly and assembly and poor integrity of the box appearance of existing clothes processing machines.

[0014] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0015] A lint filter assembly includes a detachable filter screen installed in an air duct, and a pulling mechanism arranged on the side of the air duct and extending along the disassembly direction of the filter screen. The pulling mechanism includes: a shell, which defines a channel for disassembly and assembly of the filter screen; and a pulling portion, which is pullable and arranged in the shell from an end of the shell away from the air duct, the filter screen is slidably arranged on the pulling portion, and an end of the filter screen close to the pulling mechanism at least partially extends outside the air duct, and a positioning structure for limiting the relative position between the two is provided between the pulling portion and the pulling portion.

[0016] A drying system includes an air duct, which includes a sedimentation section. The sedimentation section extends in a bottom-up direction. The lower end of the sedimentation section is provided with an air inlet of the air duct, and the upper end of the sedimentation section is provided with a condensation water inlet for introducing condensation water; a filter is provided in the air duct downstream of the sedimentation section along the air flow direction.

[0017] A clothes processing machine includes a box body and a lint filter assembly arranged in the box body, the lint filter assembly includes a filter screen extending in the front-to-back direction, and a pull-out portion connected to the front end of the filter screen and pulled out from a panel on the front side of the box body; it also includes: a buckle portion, which is embedded in the panel, one end of which is hinged to the front end of the pull-out portion, and the other end is connected to the front end of the pull-out portion by a push-lock lock; and an elastic component for driving the buckle portion to flip forward.

[0018] The present invention also provides a control method for a clothing processing machine, on which the above-mentioned lint filter assembly is provided; the control method includes: when the drying function is started, obtaining the filter position; if the filter is in the pushed-in position, executing the drying program; if the distance between the filter and the pushed-in position is less than or equal to a preset value, executing the drying program and issuing a first alarm message; if the distance between the filter and the pushed-in position is greater than the preset value, stopping the operation and issuing a second alarm message; preferably, the first alarm message and the second alarm message are different.

[0019] Preferably, when the distance between the filter screen and the bottom of the mounting groove is less than or equal to a first value, the filter screen is in a pushed-in position; when the distance between the filter screen and the bottom of the mounting groove is greater than the first value and less than or equal to a second value, the distance between the filter screen and the pushed-in position is less than or equal to a preset value; when the distance between the filter screen and the bottom of the mounting groove is greater than the second value, the distance between the filter screen and the pushed-in position is greater than the preset value.

[0020] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0021] 1. The present invention utilizes a pull-out mechanism to take out and place the filter in the air duct. By sliding the filter on the pull-out portion and providing a positioning structure between the filter and the pull-out portion for limiting the relative position therebetween, the user can take out the filter by pulling in two steps. That is, the user can first pull out the pull-out portion and then pull out the filter on the pull-out portion. Thus, the user can shorten the moving length of the pull-out portion when disassembling and maintaining the filter, thereby improving the user experience.

[0022] 2. The present invention is provided with a sedimentation section and a filter on the air duct, so that the hot and humid drying air flow blown into the air duct first flows through the sedimentation section, contacts and exchanges heat with the condensed water in the sedimentation section, and the condensed water condenses the hot and humid drying air flow, and the lint and water droplets carried in the drying air flow condense and settle, thereby realizing a primary filtration of the drying air flow. The drying air flow then flows through the filter for a secondary filtration, which can ensure the filtering effect of the lint in the drying air flow. Moreover, the filter downstream of the sedimentation section only needs to filter the residual lint in the drying air flow, which can reduce the accumulation speed of the lint on the filter, thereby reducing the frequency of cleaning the filter by users.

[0023] 3. The present invention sets the buckle part to open in a push-and-flip manner, so that the buckle part can be hidden when the filter is not being pulled out. There is no need to set a protrusion or groove on the front end of the pull-out part or the panel around the front end of the pull-out part to facilitate pulling out the pull-out part. The integrity and aesthetics of the panel can be ensured. When the filter needs to be pulled out, the buckle part is pushed open, which is convenient for the user to operate. By setting the pull-out part of the pull-out mechanism to be pulled out from the panel on the front side of the box, the convenience of the user in cleaning and disassembling the filter can be improved. The user does not need to move the clothes processing machine or bend over to pull out the filter, check the filter status, clean and maintain the filter, thereby ensuring the stability of the filter effect.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0059] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0060] As shown in FIG. 1 to FIG. 29 , in an embodiment of the present invention, a drying system 2 is introduced. The drying system 2 is applied to a clothes processing machine to dry clothes in the clothes processing machine.

[0061] The clothing processing machine includes a housing and a drum module 1 installed in the housing. The drying system 2 is connected to the drum module 1 of the clothing processing machine. The drying system 2 includes an air duct 21, a fan 22, a condensing structure 5 and a heating structure 6. The drum module 1 includes an air inlet 11 and an air outlet 12. The two ends of the air duct 21 are respectively connected to the air inlet 11 and the air outlet 12 of the drum module 1. The drying airflow is powered by the fan 22 and circulates between the air duct 21 and the drum module 1. The air is heated by the heating structure 6 and blown into the drum module 1. The hot air comes into contact with the clothes in the drum and takes away moisture in the clothes, thereby drying the clothes in the drum module 1.

[0062] In some specific embodiments, the drum module 1 includes an inner drum for accommodating clothes to be washed, and an outer drum coaxially sleeved outside the inner drum, and the drying system 2 is connected to the outer drum of the drum module 1 .

[0063] In this embodiment, the fan 22 can be provided separately or integrated within the air duct 21. Preferably, in this embodiment, the fan 22 is provided separately. The drying system 2 includes a first air duct 211, a second air duct 212, and the fan 22 connected between the first and second air ducts 211 and 212. The fan 22 provides power for the flow of the drying airflow, which flows from the second air duct 212 to the first air duct 211 under the action of the fan 22.

[0064] Example 1

[0065] As shown in FIG. 12 to FIG. 17 , in an embodiment of the present invention, a lint filter assembly 3 is introduced.

[0066] In this embodiment, the lint filtering assembly 3 is arranged in the drying system 2. Specifically, the drying system 2 is connected to the barrel module of the clothing processing machine, and includes an air duct 21 for air circulation. The lint filtering assembly 3 is arranged on the air duct 21, and is used to filter lint, hair and other debris in the air flow flowing through the air duct 21, so as to prevent lint, hair and other debris from clogging the drying system 2, thereby ensuring the drying efficiency of the drying system 2.

[0067] The lint filter assembly 3 includes a filter screen 31 and a pulling mechanism 32 for disassembling and assembling the filter screen 31 .

[0068] As shown in FIG12 , in this embodiment, the filter 31 is detachably installed in the air duct 21 for filtering the hair debris in the air duct 21 , and the pulling mechanism 32 is arranged on the side of the air duct 21 and connected to the filter 31 for disassembling the filter 31 .

[0069] When removing the filter 31 of a conventional lint filter assembly 3, it is often necessary to first pull out the pull-out portion 322 connected to the filter 31, and then continue to pull it out to remove the filter 31 connected to the pull-out portion 322. That is, the pull-out portion 322 needs to be pulled out by the length of the pull-out portion 322 plus the length of the filter 31. This long pulling distance makes it inconvenient to disassemble and maintain the filter 31. In addition, it is easy to interfere with other furniture in the user's home, seriously affecting the user's experience. This embodiment addresses this defect by improving the pull-out mechanism 32.

[0070] In this embodiment, the pulling-out mechanism 32 includes a shell 321 and a pulling-out portion 322 arranged in the shell 321. The shell 321 defines a channel for disassembly and assembly of the filter 31. The pulling-out 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-out portion 322. The end of the filter 31 close to the pulling-out 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 provided between the filter 31 and the pulling-out portion 322. In this embodiment, a pulling mechanism 32 is used to take and place the filter 31 in the air duct 21. The filter 31 is slidably set on the pulling portion 322, and a positioning structure is set between the filter 31 and the pulling portion 322 to limit the relative position between the two. The user can take out the filter 31 by pulling in two stages, that is, the user can first pull out the pulling portion 322, and then pull out the filter 31 on the pulling portion 322. In this way, the user can shorten the moving length of the pulling portion 322 when disassembling and maintaining the filter 31, thereby improving the user's experience.

[0071] Specifically, the filter 31 is arranged at a certain angle to the extension direction of the air duct 21. 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 location where the filter 31 is installed, 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.

[0072] The filter 31 can be pulled out from one side of the air duct 21 and is arranged in the air duct 21. Specifically, the filter 31 can be pulled out along its length direction in the air duct 21. The user can pull out and take the filter 31 out. The pulling mechanism 32 is set on the side of the air duct 21, and the pulling part 322 is connected to the filter 31. Therefore, the filter 31 can be pulled out and taken out through the pulling mechanism 32.

[0073] In this embodiment, the pull-out mechanism 32 extends in the direction of removal of the filter 31. Specifically, a removal opening for installing and removing the filter 31 is provided on the sidewall of the air duct 21. The housing 321 is mounted at the removal opening on the air duct 21. The end of the channel of the housing 321 that interfaces with the air duct 21 is arranged around the removal opening on the air duct 21, and the channel extends along the length of the filter 31. The shape of the pull-out portion 322 matches the shape of the channel and reciprocates within the channel of the housing 321.

[0074] Preferably, in this embodiment, an annular sealing strip is provided between the shell 321 and the side wall of the air duct 21. The sealing strip is arranged around the taking-in and putting-out opening of the filter 31 on the air duct 21, and is used to seal the connecting position between the air duct 21 and the shell 321 of the pull-out portion 322 to prevent leakage of airflow and wire scraps.

[0075] In some preferred embodiments, the air duct 21 is configured to be flat with a rectangular cross-section, the filter 31 extends along the width direction of the air duct 21 , and the disassembly direction of the filter 31 is perpendicular to the extension direction of the air duct 21 .

[0076] As shown in Figures 14 and 16, the drawer portion 322 is in the shape of a strip plate and has a certain thickness. The shape of the drawer portion 322 is adapted to the shape of the passage of the housing 321. The drawer portion 322 is retractable from the end of the housing 321 away from the air duct 21 and is disposed within the housing 321, forming a sliding pair between the drawer portion 322 and the housing 321. A guide groove 322-1 extending along the length of the drawer portion 322 is provided on one side of the drawer portion 322. The filter 31 is slidably disposed within the guide groove 322-1, forming another sliding pair between the filter 31 and the drawer portion 322.

[0077] In this embodiment, the pull-out portion 322 has an extended position and an inserted position relative to the housing 321. To remove the filter 31, the pull-out portion 322 is first pulled out to the extended position. At this point, the end of the filter 31 near the pull-out mechanism 32 at least partially extends outside the passage. That is, when the pull-out portion 322 is moved to the extended position, the end of the filter 31 near the pull-out mechanism 32 at least partially extends outside the end of the housing 321 away from the air duct 21. At this point, the user can pull the filter 31 out through the end of the filter 31 that extends outside the housing 321.

[0078] Preferably, as shown in Figures 14 and 17, in this embodiment, a first handle portion 312-1 is provided at one end of the filter 31 near the drawer mechanism 32. The first handle portion 312-1 is annular and formed at the end of the filter 31 near the drawer mechanism 32. The user can use the first handle portion 312-1 to draw the filter 31. When the drawer portion 322 moves to the withdrawn position, at least the first handle portion 312-1 moves to the outside of the housing 321.

[0079] In this embodiment, the filter screen 31 is slidably disposed within the guide groove 322-1, and the depth of the guide groove 322-1 is greater than or equal to the thickness of the filter screen 31. Preferably, the depth of the guide groove 322-1 is equal to the thickness of the filter screen 31. The filter screen 31 is embedded within the guide groove 322-1, with the side of the filter screen 31 near the bottom of the guide groove 322-1 in contact with the bottom of the guide groove 322-1, and the side of the filter screen 31 away from the bottom of the guide groove 322-1 being coplanar with the plane of the notch of the guide groove 322-1.

[0080] In this embodiment, the outer side of the groove wall of the guide groove 322-1 fits with the inner wall of the channel. Preferably, the outer sides of the two groove walls of the guide groove 322-1 fit with the upper and lower inner walls of the channel respectively, and the left and right sides of the pull-out portion 322 fit with the left and right inner walls of the channel.

[0081] A cooperating guide groove 3-2 and guide rib 3-1 are provided between the inner wall of the guide groove 322-1 and the filter 31. Specifically, the guide groove 3-2 is provided on the wall of the guide groove 322-1 or on the sidewall of the filter 31, extending along the length of the drawer 322. The guide rib 3-1 is provided on the sidewall of the filter 31 or on the wall of the guide groove 322-1, extending along the length of the drawer 322. The guide rib 3-1 is mounted within the guide groove 3-2 and slides along the guide groove 3-2. The guide groove 3-2 and guide rib 3-1 cooperate to retain the filter 31 within the guide groove 322-1, limiting the relative movement between the filter 31 and the drawer 322 to sliding movement along the length of the guide groove 322-1.

[0082] Preferably, in this embodiment, a guide groove 3-2 is provided on one of the two groove walls of the guide groove 322-1, and a guide rib 3-1 is provided on the other, and corresponding guide ribs 3-1 and guide grooves 3-2 are provided on the side walls of the filter screen 31 respectively.

[0083] Preferably, in this embodiment, the bottom of the guide groove 322-1 extends along the length direction of the pull-out portion 322, the groove wall of the guide groove 322-1 is arranged perpendicular to the groove bottom of the guide groove 322-1, and the depth direction of the guide groove 3-2 is perpendicular to the length direction of the pull-out portion 322, that is, the depth direction of the guide groove 3-2 is perpendicular to the groove wall of the guide groove 322-1.

[0084] The filter 31 is installed and removed from the side of the drawer portion 322 on the side where the guide groove 322-1 is provided. Specifically, the guide groove 3-2 and / or guide ridge 3-1 on the wall of the guide groove 322-1 bends away from the air duct 21, at least on the end thereof away from the air duct 21, toward the bottom of the guide groove 322-1. The end surface of the drawer portion 322, flush with the notch of the guide groove 322-1, is provided with an installation opening 3-3 for removing and placing the filter 31.

[0085] In this embodiment, the guide grooves 3-2 and guide ribs 3-1 on the walls of guide groove 322-1 correspond to each other. The guide ribs 3-1 and guide grooves 3-2 are arranged on the side walls of filter screen 31 so as to correspond to each other. The guide ribs 3-1 on the side walls of filter screen 31 slide in engagement with the guide grooves 3-2 on the walls of guide groove 322-1. The guide grooves 3-2 on the side walls of filter screen 31 slide in engagement with the guide ribs 3-1 on the walls of guide groove 322-1. Specifically, the width of filter screen 31 extends longitudinally, and the upper and lower side walls of filter screen 31 slide in engagement with the walls of guide groove 322-1.

[0086] The filter 31 is made of an elastic material. When the user pulls the filter 31 away from the air duct 21, the filter 31 moves along the guide groove 3-2 and guide rib 3-1 on the wall of the guide groove 322-1. When the filter 31 reaches the position where the guide groove 3-2 and guide rib 3-1 on the wall of the guide groove 322-1 bend, it elastically deforms and bends accordingly. An installation opening 3-3 for removing the filter 31 is located on the end of the guide groove 3-2 and guide rib 3-1 on the wall of the guide groove 322-1 that is away from the air duct 21 and away from the bottom of the guide groove 322-1. The filter 31 can be removed and installed through the installation opening 3-3 from a plane on the pull-out portion 322 that is coplanar with the notch of the guide groove 322-1.

[0087] Preferably, in this embodiment, a smooth transition is formed between the guide groove 3-2 on the groove wall of the guide groove 322-1, which is close to the groove bottom of the guide groove 322-1, and the side surface of the drawer portion 322, which is on the side of the mounting opening 3-3 away from the air duct 21. The end of the guide ridge 3-1 on the groove wall of the guide groove 322-1, which is away from the air duct 21, corresponds to the middle of the mounting opening 3-3 on the guide groove 3-2 on the groove wall of the other guide groove 322-1. This ensures that the upper and lower sides of the filter 31 can be removed and installed simultaneously.

[0088] Preferably, both ends of the guide rib 3-1 are provided with guide portions whose thickness gradually decreases as they move away from each other. That is, the thickness of the end of the guide rib 3-1 that is closer to the air duct 21 gradually decreases as it approaches the air duct 21, while the thickness of the end of the guide rib 3-1 that is farther from the air duct 21 gradually decreases as it moves away from the air duct 21. Specifically, the side of the guide portion that is opposite the notch of the guide groove 322-1 and the side of the guide portion that is opposite the bottom of the guide groove 322-1 are each provided with an arcuate surface. Preferably, the arcuate surface on the side of the guide portion that is opposite the groove wall of the guide groove 322-1 extends longer than the arcuate surface on the side of the guide portion that is opposite the notch of the guide groove 322-1.

[0089] In this embodiment, the guide groove 3-2 and the guide rib 3-1 on the groove wall of the guide groove 322-1 can be set as a whole to be an arc that bends along the direction away from the air duct 21 toward the side of the groove opening of the guide groove 322-1, or only the end of the guide groove 3-2 and the guide rib 3-1 on the groove wall of the guide groove 322-1 away from the air duct 21 can be set as an arc that bends along the direction away from the air duct 21 toward the side of the groove opening of the guide groove 322-1.

[0090] Preferably, in this embodiment, the bending position of the guide groove 3-2 and the guide edge 3-1 on the groove wall of the guide groove 322-1 is only set at one end away from the air duct 21 to ensure that after the filter 31 is installed on the pull-out portion 322, the filter 31 as a whole remains straight, thereby reducing the stress between the filter 31 and the pull-out portion 322, improving the service life of the filter 31, and at the same time, avoiding the filter 31 from protruding from the guide groove 322-1, ensuring the smoothness of pulling the pull-out portion 322.

[0091] In this embodiment, the side of the filter 31 opposite to the bottom of the guide groove 322-1 abuts and slides with the bottom of the guide groove 322-1. Preferably, at least one end of the bottom of the guide groove 322-1 away from the air duct 21 bends along the direction away from the air duct 21 toward the direction close to the slot of the guide groove 322-1.

[0092] Preferably, the bottom of the guide groove 322-1 is parallel to the extending direction of the guide groove 3-2 and / or the guide rib 3-1 on the groove wall of the guide groove 322-1, and smoothly transitions to the side surface of the pull-out portion 322. Specifically, the bottom of the guide groove 322-1 is parallel to the extending direction of the guide groove 3-2 and the guide rib 3-1 on the groove wall of the guide groove 322-1.

[0093] In this embodiment, after the filter 31 is installed in the guide groove 322-1 on the pull-out portion 322, the filter 31 is connected to the pull-out portion 322 through the positioning structure between the end of the filter 31 away from the air duct 21 and the pull-out portion 322 to avoid relative sliding between the two. Therefore, in the process of pushing and pulling the pull-out portion 322 in and out, the filter 31 follows the pull-out portion 322 to be pushed into the air duct 21 or pulled out from the air duct 21.

[0094] As shown in FIG. 14 , in this embodiment, an end of the pull-out portion 322 close to the air duct 21 at least partially overlaps with an end of the filter 31 close to the pull-out mechanism 32 .

[0095] The positioning structure can be any detachable structure, such as a screw structure, a magnetic structure, and a snap-fit ​​structure. Specifically, after the filter 31 is installed on the pull-out portion 322, it can be positioned by passing through the filter 31 and tightening a screw on the pull-out portion 322, and / or, a magnetic structure can be set between the end of the filter 31 away from the air duct 21 and the pull-out portion 322. After the filter 31 is installed on the pull-out portion 322, the magnetic structures between the two are attracted to each other to achieve positioning between the filter 31 and the pull-out portion 322, and / or, after the filter 31 is installed on the pull-out portion 322, it can be positioned by a snap-fit ​​structure set between the end of the filter 31 away from the air duct 21 and the pull-out portion 322.

[0096] Preferably, in this embodiment, the filter 31 and the drawer 322 are positioned together using a snap-fit ​​structure. Specifically, the snap-fit ​​structure includes a snap 312-2 provided on the filter 31 and a first slot 322-5 provided on the drawer 322 and adapted to the snap 312-2. The snap 312-2 is provided at the end of the filter 31 near the drawer 32 and is bent toward the side near the drawer 322. The first slot 322-5 is provided in the middle of the drawer 322 or at the end of the drawer 322 near the air duct 21 and engages with the snap 312-2.

[0097] The buckle 312-2 is provided on the first handle portion 312-1, and bends and extends toward one side of the bottom of the guide groove 322-1 in a direction perpendicular to the pull portion 322. The first locking groove 322-5 is provided in the middle of the push-pull portion.

[0098] In this embodiment, the distance between the first latching slot 322 - 5 at the pushed-in position of the drawer portion 322 and the inner wall of the air duct 21 away from the drawer mechanism 32 is equal to the length of the filter 31 .

[0099] In this embodiment, an avoidance groove 322-2 is provided on the bottom of the guide groove 322-1 for avoiding the buckle 312-2. 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 straight part of the bottom of the guide groove 322-1. During the disassembly and assembly of the filter 31, the buckle 312-2 on the filter 31 moves along the avoidance groove 322-2, which can improve the smoothness of the disassembly and assembly of the filter 31.

[0100] The first engaging slot 322-5 is provided at an end of the avoidance slot 322-2 near the air duct 21. Specifically, the end of the filter 31 away from the air duct 21 corresponds to the point where the bottom of the guide slot 322-1 begins to bend away from the air duct 21 toward the notch of the guide slot 322-1. When the user pulls the filter 31 to disengage the buckle 312-2 from the first engaging slot 322-5, the guide groove 3-2 and guide ridge 3-1 on the wall of the guide slot 322-1 begin to bend away from the air duct 21 toward the side near the notch of the guide slot 322-1, allowing the buckle 312-2 to smoothly disengage from the first engaging slot 322-5 and the filter 31 to be smoothly withdrawn.

[0101] In this embodiment, when the pull-out portion 322 moves to the pushed-in position, the end of the pull-out portion 322 close to the air duct 21 is flush with the end of the shell 321 close to the air duct 21, and the end of the pull-out portion 322 away from the air duct 21 at least partially extends outside the shell 321, allowing the user to pull the pull-out portion 322.

[0102] Preferably, the inner wall of the first slot 322 - 5 on the side away from the air duct 21 , at least one end close to the filter 31 , is configured as an inclined surface inclined from the direction close to the filter 31 toward the side away from the air duct 21 .

[0103] Preferably, in this embodiment, a positioning device is further provided between the housing 321 and the drawer portion 322 , and the positioning device is used to lock the drawer portion 322 in the drawer portion when the drawer portion 322 moves to the drawer portion.

[0104] Specifically, as shown in Figures 13 and 15, in this embodiment, the guide groove 322-1 is provided on the first side surface of the drawer 322, and the positioning device is provided between the second side surface of the drawer 322 and the housing 321. The positioning device includes an elastic positioning arm 321-1 and a second latching groove 322-4. The elastic positioning arm 321-1 is provided on the side of the drawer 322 away from the filter 31, one end of which is connected to the housing 321, and the other end of which is provided with a positioning protrusion 321-2. The elastic positioning arm 321-1 abuts against the drawer 322 via the positioning protrusion 321-2. The second latching groove 322-4 is provided on the drawer 322 on the side of the first latching groove 322-5 near the air duct 21, and is adapted to the positioning protrusion 321-2. When the drawer 322 is withdrawn, the positioning protrusion 321-2 is engaged with the second latching groove 322-4 to position the drawer 322 in the withdrawn position.

[0105] By providing an elastic positioning arm 321-1, the drawer 322 can be positioned in the extended position, making it easier for the user to remove and install the filter 31 on the drawer 322. This also prevents the user from pulling the drawer 322 too far, making it difficult to install the filter, further improving the user's convenience in removing and installing the filter 31 and enhancing the user experience. By arranging the second slot 322-4 on the side of the first slot 322-5 closer to the air duct 21, it ensures that when the elastic positioning arm 321-1 is inserted into the second slot 322-4, the end of the filter 31 away from the air duct 21 can extend outside the housing 321, making it easier for the user to remove the filter 31.

[0106] Preferably, in this embodiment, the elastic positioning arm 321 - 1 is provided at one 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 shell body 321 corresponding to the second side surface of the pull-out portion 322, and the groove includes a first wall arranged opposite to the second side surface of the pull-out portion 322, and a second wall arranged at one end of the first wall close to the air duct 21 and opposite to the opening of the end of the shell body 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 pull-out portion 322 in the direction away from the air duct 21. The elastic positioning arm 321-1 is inclined along the extension direction away from the air duct 21 toward the side close to the pull-out portion 322. A positioning protrusion 321-2 is provided on the side of the elastic positioning arm 321-1 close to the pull-out portion 322. The positioning protrusion 321-2 is adapted in shape to the second slot 322-4 on the pull-out portion 322, and the elastic positioning arm 321-1 abuts against the pull-out portion 322 through the positioning protrusion 321-2.

[0107] Preferably, in this embodiment, the second wall of the groove is configured to be an arc with the middle portion convex toward the direction close to the air duct 21, and a U-shaped groove structure is formed between the first wall, the second wall and the elastic positioning arm 321-1, and the U-shaped groove structure is provided with reinforcing ribs extending along the first wall, the second wall and the elastic positioning arm 321-1.

[0108] Preferably, a spring sheet is provided between the first wall and the elastic positioning arm 321 - 1 , and the spring sheet is clamped and positioned with the housing 321 . The spring sheet is U-shaped and fits into the U-shaped groove structure formed by the first wall, the second wall and the elastic positioning arm 321 - 1 .

[0109] Preferably, the second slot 322-4 and the first slot 322-5 are staggered with each other in the length direction of the pull-out portion 322, and / or the size and / or shape of the positioning protrusion 321-2 are different from those of the first slot 322-5, so as to prevent the positioning protrusion 321-2 from being stuck in the first slot 322-5.

[0110] Preferably, in this embodiment, the elastic positioning arm 321-1 at least partially extends to the outside of the end of the housing 321 away from the air duct 21. Therefore, the user can release the locking of the pull-out portion 322 by pushing the end of the elastic positioning arm 321-1.

[0111] Preferably, in this embodiment, the inner wall of the second slot 322-4 on the side away from the air duct 21 is provided with an inclined surface inclined toward the side away from the air duct 21 along the direction away from the filter 31; and / or, a guide platform 312-3 is provided on the filter 31, and the guide platform 312-3 at least partially extends from the side of the second slot 322-4 away from the air duct 21 to the inside of the second slot 322-4, and the guide platform 312-3 is configured as a triangle with a height gradually increasing along the direction away from the air duct 21; and an avoidance opening 322-3 for the guide platform 312-3 to slide is provided on the pull-out portion 322.

[0112] Specifically, as shown in Figure 15 , the filter 31 is provided with a guide platform 312-3. The guide platform 312-3 protrudes from the side of the filter 31 near the pull-out portion 322. The height of the guide platform 312-3 gradually increases as it moves away from the air duct 21, and a smooth transition is formed between the end of the guide platform 312-3 near the air duct 21 and the side of the filter 31. The avoidance opening 322-3 communicates with the second slot 322-4 from the side away from the air duct 21 and extends from the side of the second slot 322-4 away from the air duct 21 along the length of the pull-out portion 322 away from the air duct 21. The avoidance opening 322-3 is used to accommodate and guide the guide platform 312-3 on the filter 31 when the filter 31 is withdrawn.

[0113] When the filter 31 is installed on the drawer 322, that is, when the buckle 312-2 is engaged with the first slot 322-5, the guide platform 312-3 is positioned at the junction between the avoidance opening 322-3 and the second slot 322-4. The guide platform 312-3 at least partially extends from the side of the second slot 322-4 away from the air duct 21 into the second slot 322-4. Therefore, when the drawer 322 is pushed in, the guide platform 312-3, whose inclined surface slopes from away from the air duct 21 toward the side closer to the drawer 322, contacts the positioning protrusion 321-2. The guide platform 312-3 pushes the positioning protrusion 321-2 out of the second slot 322-4, allowing the drawer 322 to be smoothly pushed in.

[0114] By providing an inclined surface on the inner wall of the second slot 322-4 away from the air duct 21, which is inclined toward the side away from the air duct 21 along the direction away from the filter 31, and / or providing a guide platform 312-3 on the filter 31, when the user pushes the pull-out portion 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 second slot 322-4 away from the air duct 21 and / or through the guide platform 312-3, so that the elastic positioning arm 321-1 releases the lock on the pull-out portion 322, thereby improving the smoothness of the pulling-out process of the pull-out portion 322.

[0115] In this embodiment, the guide platform 312-3 includes a hole section that passes through the pull-out portion 322 and a slot section with the slot opening facing the side where the filter 31 is located. The slot section is arranged at the end of the hole section away from the air duct 21. The bottom of the slot section is close to the end of the air duct 21, and the slot wall on the side of the slot section away from the air duct 21 is arranged to be an inclined surface inclined along the direction away from the air duct 21 toward the side close to the filter 31, so as to improve the smoothness of pulling the filter 31 out of the pull-out portion 322.

[0116] As shown in FIG. 12 , in this embodiment, the lint filter assembly 3 further includes a sensing assembly 33 . The sensing assembly 33 is disposed between the end of the filter 31 and the inner wall of the air duct 21 for detecting the installation position of the filter 31 .

[0117] Specifically, the sensor assembly 33 is positioned between the inner wall of the air duct 21, away from the pull-out mechanism 32, and the end of the filter 31. The sensor assembly 33 may be an infrared sensor module or a reed switch. The provision of the sensor assembly 33 improves the reliability of the lint filter assembly 3 and ensures effective lint filtering. The sensor assembly 33 is communicatively connected to the control unit of the laundry machine.

[0118] Preferably, in this embodiment, a mounting groove 2125 for accommodating the end of the filter 31 is provided on the inner wall of the air duct 21. The mounting groove 2125 is provided on the inner wall of the air duct 21 away from the pulling mechanism 32. When the filter 31 is installed in the air duct 21, the end of the filter 31 away from the pulling part 322 is inserted into the mounting groove 2125 to ensure the installation stability and working reliability of the filter 31.

[0119] The sensing component 33 is arranged between the bottom of the mounting groove 2125 and the end of the filter 31. The maximum detection distance of the sensing component 33 is less than or equal to the groove depth of the mounting groove 2125. Therefore, the sealing performance and normal operation can be guaranteed in the fuzzy area recognized by the sensing component 33, further improving the user experience.

[0120] In some specific embodiments, the sensing assembly 33 comprises a cooperating reed switch and a magnet. The reed switch is positioned at the bottom of the mounting slot 2125, and the magnet is positioned at the end of the filter 31 away from the drawer mechanism 32. The maximum detection distance of the reed switch is less than or equal to the depth of the mounting slot 2125. When the reed switch detects the magnet, it indicates that the end of the filter 31 is at least partially inserted into the mounting slot 2125. At this point, the airflow through the air duct 21 is guaranteed to be filtered by the filter 31.

[0121] Specifically, in this embodiment, the magnetic block is embedded on the end surface of the filter 31 away from the drawer portion 322 .

[0122] When the reed switch detects the position of the magnetic block, as the magnetic block approaches the reed switch, the reed switch has a transition identification area with fuzzy identification and an area where it can be clearly identified. When the reed switch can clearly identify the magnetic block, it is determined that the filter 31 is in the pushed-in position, and the two reeds of the reed switch are attracted. When the magnetic block stays in the transition identification area of ​​the reed switch, the two reeds of the reed switch may be judged to be attracted, or may not be attracted, and may fluctuate between attraction and disconnection.

[0123] In this embodiment, the setting of the installation groove 2125 can ensure that when the reed switch initially recognizes the magnetic block, the filter 31 can stably play its role. Even if the subsequent reed switch judgment fluctuates between attraction and disconnection, the filter 31 can also stably play its filtering role. At this time, it is judged that the drying process can proceed smoothly.

[0124] In this embodiment, the reed switch can also be replaced by an infrared detection module, which accurately detects the distance between the end of the filter 31 away from the pulling mechanism 32 and the bottom of the installation groove 2125.

[0125] In this embodiment, a control method for a clothes processing machine is also provided. The clothes processing machine is provided with the above-mentioned lint filter assembly 3. The control method includes:

[0126] When the drying function is started, the position of the filter 31 is obtained;

[0127] If the filter 31 is in the pushed-in position, the drying process is performed;

[0128] If the distance between the filter 31 and the pushed position is less than or equal to the preset value, the drying process is executed and a first alarm message is issued;

[0129] If the distance between the filter screen 31 and the pushed-in position is greater than a preset value, the operation is stopped and a second alarm message is issued.

[0130] In this embodiment, the first alarm information and the second alarm information may be prompt sounds, and / or lights, and / or push messages.

[0131] Preferably, in this embodiment, the first alarm information and the second alarm information are different.

[0132] In this embodiment, when the distance between the filter 31 and the bottom of the installation groove 2125 is less than or equal to a first value, it is defined that the filter 31 is in the pushed-in position. When the filter 31 is in the pushed-in position, the clothes processing machine operates normally; when the distance between the filter 31 and the bottom of the installation groove 2125 is greater than the first value and less than or equal to the second value, it is defined that the distance between the filter 31 and the pushed-in position is less than or equal to the preset value. At this time, the clothes processing machine executes the drying program and issues a first alarm message; when the distance between the filter 31 and the bottom of the installation groove 2125 is greater than the second value, it is defined that the distance between the filter 31 and the pushed-in position is greater than the preset value. At this time, the clothes processing machine stops running and issues a second alarm message.

[0133] 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.

[0134] 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.

[0135] In this embodiment, the clothes processing machine can be a dryer or a washer-dryer.

[0136] Specifically, the air inlet 11 is arranged at the top front end of the barrel module 1, and the air outlet 12 is arranged at the top rear end of the barrel module 1. The air inlet 11 and the air outlet 12 are located on both sides of the central axis of the barrel module 1 in the horizontal direction. The air duct 21 includes a first air duct 211 extending backward from the air inlet 11 along the axial direction of the barrel module 1, and a second air duct 212 extending laterally from the rear end of the first air duct 211 and connected to the air outlet 12.

[0137] The filter 31 is arranged in the air duct 21 on the upper rear side of the barrel module 1 and is taken in and out from the side of the box. If a conventional pulling mechanism 32 is used, the pulling part 322 needs to be pulled out a long distance to pull out the filter 31. This embodiment improves the pulling mechanism 32 to address this defect.

[0138] Specifically, in this embodiment, the second air duct 212 extends horizontally in the left-right direction at the top rear side of the barrel module 1. The filter 31 is disposed within the second air duct 212 and extends in the front-to-back direction. The pull-out portion 322 of the pull-out mechanism 32 is drawn from the front panel of the housing. Conventional pull-out mechanisms 32 require the front end of the pull-out portion 322 to be pulled out the distance between the panel and the rear side of the second air duct 212 in order to extract the filter 31. However, the purpose of this embodiment is to extract the filter 31 with a shorter pull-out distance. In this embodiment, the filter 31 is disposed within the second air duct 212, near one end of the barrel module 1's air outlet 12.

[0139] Preferably, in this embodiment, the access opening of the filter 31 is arranged at the front side of the second air duct 212, and the user pulls out and takes out the filter 31 from the front end of the clothes processing machine.

The lint filter assembly includes a filter 31 arranged in the second air duct 212. The lint entering the drying system 2 is filtered through the filter 31 to prevent the lint from entering the fan 22.

[0223] Further preferably, in this embodiment, the filter 31 is disposed at an end of the second air duct 212 away from the first air duct 211 .

[0224] Example 4

[0225] As shown in Figures 19 and 26 to 29, an embodiment of the present invention describes a drying system 2, which is applied to a laundry machine and is used to dry laundry within a drum module 1 of the laundry machine. Drying system 2 also includes a lint filter assembly 3, which includes a filter 31 disposed within an air duct 21 for filtering lint entering the air duct 21. Filter 31 is detachably mounted within air duct 21 and further includes a pull-out mechanism 32 for removing filter 31.

[0226] In this embodiment, a replacement solution for the lint filter assembly in the above-mentioned embodiment 1 is specifically provided, which is also used to solve the problem in the prior art that when the filter 31 is set in the air duct on the upper rear side of the barrel module 1, it is taken out and placed from the side of the box. If a conventional pulling mechanism is used, the pulling part needs to be pulled out a long distance to pull out the filter, which results in a poor user experience.

[0227] The lint filtering assembly in this embodiment can be applied to the drying systems in the above-mentioned second and third embodiments.

[0228] Specifically, in this embodiment, the second air duct 212 extends horizontally in the left-right direction at the top rear side of the cartridge module. The filter 31 is disposed within the second air duct 212 and extends in the front-to-back direction. The pull-out portion of the pull-out mechanism is drawn from the front panel of the housing. Conventional pull-out mechanisms require the front end of the pull-out portion to be pulled out the distance between the panel and the rear side of the second air duct in order to remove the filter. This embodiment aims to remove the filter with a shorter pull-out distance.

[0229] In this embodiment, the filter 31 is disposed within the second air duct 212, near one end of the air outlet of the cartridge module 1. The filter 31 is disposed at a certain angle to the extension direction of the second air duct 212, covering the cross-section of the filter 31 along the width direction, so that all airflow passing through the second air duct 212 is filtered by the filter 31. The extension direction of the filter 31 can be perpendicular to the extension direction of the second air duct 212, or it can be non-perpendicular, as long as the projection of the filter 31 can cover the cross-section of the second air duct 212.

[0230] The filter 31 can be pulled out from one side of the second air duct 212 and is arranged in the second air duct 212. The user can pull out the filter 31 to take it in and put it in. The pulling mechanism 32 is set on the side of the second air duct 212 and is connected to the filter 31. Therefore, the filter 31 can be pulled out and put in by the pulling mechanism 32.

[0231] Preferably, in this embodiment, the access opening of the filter 31 is arranged at the front side of the second air duct 212, and the user pulls out and takes out the filter 31 from the front end of the clothes processing machine.

[0232] Specifically, the pulling mechanism 32 includes a shell 321 and a pulling portion 322 installed in the shell 321. The shell 321 is configured as a strip, extending from the removal port of the filter 31 along the pulling direction of the filter 31. The pulling portion 322 is slidably arranged in the shell 321. The pulling portion 322 is connected to the filter 31, and the pulling portion 322 extends in the shell 321 along the pulling direction of the filter 31. Therefore, the user can pull out and remove the filter 31 through the pulling portion 322 to realize the disassembly, replacement, maintenance and cleaning of the filter 31.

[0233] The existing pull-out portion 322 is generally directly connected to the end of the filter 31. When the user takes out the filter 31, the user needs to first pull out the pull-out portion 322 completely, and then continue to pull out the pull-out portion 322 to pull out the filter 31. The sum of the lengths of the pull-out portion 322 and the filter 31 needs to be pulled out. The disassembly process is very inconvenient, which seriously affects the user experience.

[0234] In this regard, in an embodiment of the present invention, the pull-out portion 322 of the pull-out mechanism 32 is disposed within the housing 321 and can be pulled out from the end of the housing 321 away from the air duct 21. The pull-out portion 322 is connected to the filter 31 via a transmission device 325. When the pull-out portion 322 is pulled out, the filter 31 is driven to slide relative to the pull-out portion 322. In this embodiment, the filter 31 within the air duct 21 is pulled out using the pull-out mechanism 32. By setting the pull-out portion 322 of the pull-out mechanism 32 to be connected to the filter 31 via a transmission device 325, the filter 31 is driven to slide relative to the pull-out portion 322. This allows the user to move the filter 31 in the same direction at a relatively fast speed when moving the pull-out portion 322. This shortens the distance the user must move the pull-out portion 322 when disassembling and maintaining the filter 31, thereby improving the user experience.

[0235] Preferably, in this embodiment, the second air duct 212 is a flat pipe extending horizontally and having a rectangular cross-section. The taking-in and putting-out opening of the filter 31 is opened on the front side of the second air duct 212. The pulling direction of the filter 31 is perpendicular to the extension direction of the second air duct 212, that is, the filter 31 is pulled along the front-to-back direction.

[0236] The shell 321 is arranged on the front side of the second air duct 212 and extends horizontally in the front-to-back direction. The rear port of the shell 321 is connected to the take-in and put-out port on the second air duct 212. The front end of the filter 31 at least partially extends into the shell 321 and is transmission-connected to the pull-out part 322. The pull-out part 322 pulls the filter 31 out of the channel in the shell 321.

[0237] In this embodiment, the pull-out portion 322 is connected to the filter screen 31 through a transmission device 325 . The transmission device 325 is a gear 3253 rack transmission device 325 , which includes a first rack 3251 , a second rack 3252 and a gear 3253 .

[0238] In some possible embodiments, the first rack 3251 is installed on the shell 321 and extends along the pulling direction of the pulling portion 322. The second rack 3252 is installed on the filter 31 and is parallel to the first rack 3251. The first rack 3251 and the second rack 3252 are arranged opposite to each other. The gear 3253 is installed on the pulling portion 322 through a rotating shaft and is arranged between the first rack 3251 and the second rack 3252. The two sides are respectively engaged with the first rack 3251 and the second rack 3252 for transmission.

[0239] Thus, when the user pulls the pull-out portion 322, the gear 3253 rotates under the action of the first rack 3251, and drives the filter 31 to produce a same-direction displacement relative to the pull-out portion 322 through the second rack 3252. That is, during the movement of the pull-out portion 322, the filter 31 is driven by the gear 3253 rack to synchronously produce a faster same-direction displacement, thereby shortening the moving length of the pull-out portion 322 when the user disassembles and maintains the filter 31.

[0240] In this embodiment, the number of the gear 3253 is one. In this case, the moving speed of the filter 31 relative to the housing 321 is twice the moving speed of the drawer 322 relative to the housing 321 .

[0241] Preferably, in this embodiment, the gears 3253 can also be set to be two coaxially arranged and circumferentially limited connected, and the two gears 3253 are respectively engaged with the first rack 3251 and the second rack 3252. Thus, by changing the size of the two gears 3253, the speed difference between the filter 31 and the pull-out part 322 can be changed, that is, the moving speed of the filter 31 relative to the pull-out part 322 can be changed.

[0242] In other possible embodiments, the first rack 3251 of the transmission device 325 is installed on the pulling portion 322 and extends along the pulling direction of the pulling portion 322. The second rack 3252 is installed on the filter 31, parallel to the first rack 3251, and arranged opposite to the first rack 3251. The gear 3253 is installed on the shell 321, including a first gear 3253 and a second gear 3253 coaxially arranged and circumferentially limited, and a third gear 3253 arranged between the first gear 3253 and the first rack 3251, or between the second gear 3253 and the second rack 3252. One of the first gear 3253 and the second gear 3253 is meshed with the first rack 3251 or the second rack 3252 through the third gear 3253, and the other of the first gear 3253 and the second gear 3253 is directly meshed with the first rack 3251 or the second rack 3252.

[0243] In this embodiment, the function of the third gear 3253 is to make the moving direction of the filter 31 consistent with the moving direction of the drawer 322 .

[0244] Preferably, in this embodiment, the pull-out portion 322 drives the first gear 3253 and the second gear 3253 to rotate synchronously in the first direction through the first rack 3251, the second gear 3253 drives the third gear 3253 to rotate in the second direction, and the third gear 3253 drives the filter 31 and the pull-out portion 322 to move in the same direction through the second rack 3252.

[0245] In this embodiment, the ratio of the diameters of the first gear 3253 and the second gear 3253 is equal to the ratio of the displacement of the pull-out portion 322 relative to the housing 321 and the displacement of the filter screen 31 relative to the housing 321.

[0246] Preferably, in this embodiment, the width of the second air duct 212 is less than or equal to the distance between the end of the filter 31 and the front end of the housing 321. Preferably, the diameter of the second gear 3253 is twice the diameter of the first gear 3253.

[0247] In this embodiment, the drawer portion 322 is configured to be plate-shaped, the filter screen 31 is disposed on a first side of the drawer portion 322 , and the transmission device 325 is disposed on a second side of the drawer portion 322 .

[0248] Specifically, the pull-out portion 322 is configured as a strip plate perpendicular to the extension direction of the second air duct 212, the filter 31 is longitudinally arranged on the first side of the pull-out portion 322, and the lower end of the filter 31 is provided with a transmission portion 313 that extends laterally and at least partially extends to the second side of the pull-out portion 322, and the transmission device 325 is arranged between the transmission portion 313, the shell 321 and the pull-out portion 322.

[0271] Example 5

[0272] In this embodiment, the clothes processing machine includes a lint filter assembly 3, which is used to filter lint.

[0273] Preferably, the lint filter assembly 3 can be used to filter the washing water flow, and can also be used to filter the drying air flow. In this embodiment, the lint filter assembly 3 filtering the drying air flow is used as an example for discussion.

[0274] The lint filter assembly 3 includes a filter screen 31 disposed in the air duct 21 and a pulling mechanism 32 disposed outside the air duct 21 for pulling out and disassembling the filter screen 31 .

[0275] In this embodiment, the lint filter assembly 3 may be the lint filter assembly 3 in the above-mentioned embodiment 1 or embodiment 4, and may be applied to the drying system in the above-mentioned embodiment 2 or embodiment 3.

[0277] A decorative panel 323 for shielding the pulling mechanism 32 is embedded on the panel. The material, color, and / or glossiness of the decorative panel 323 are consistent with those of the panel. When the pulling part 322 of the pulling mechanism 32 is reset, the decorative panel 323 is embedded in the panel, and the peripheral side of the decorative panel 323 transitions smoothly with the panel.

[0278] The housing 100 is further provided with a detergent box 71 for storing detergent. The detergent box 71 is drawable and arranged on the front side of the housing 100 . Specifically, the detergent box 71 can be drawn from the panel of the housing 100 .

[0279] The front end of the detergent box 71 is provided with a front decorative panel 72 for engaging with the panel and shielding the detergent box 71. The material, color, and / or glossiness of the front decorative panel 72 are consistent with those of the panel. When the detergent box 71 is closed, the front decorative panel 72 is engaged with the panel, and the peripheral side of the front decorative panel 72 has a smooth transition with the panel.

[0280] In this embodiment, the panel can be divided into two areas, including a main control panel area for controlling the clothes processing machine and a front decorative panel 72 area for pulling out the detergent box 71 .

[0281] The panel can also be divided into three areas, including a main control panel area for controlling the clothes processing machine, a front decorative panel 72 area for pulling out the detergent box 71, and a decorative panel 323 area for pulling out the lint filter assembly 3.

[0282] In this embodiment, a control switch, and / or a display screen, and / or a knob, and / or a control button, and / or a touch screen, etc. can be set in the main control panel area. The main control panel is communicated with the control computer board of the clothing processing machine for the user to input control instructions and to provide feedback to the user on the working status of the clothing processing machine.

[0283] In this embodiment, the detergent box 71 is disposed on one side of the pulling mechanism 32 of the debris filtering assembly 3 .

[0284] In some possible embodiments, the front decorative panel 72 of the detergent box 71 constitutes a decorative panel 323 for shielding the drawing mechanism 32 .

[0285] Specifically, the pulling mechanism 32 is arranged on one side of the detergent box 71 and adjacent to the detergent box 71. The front decorative panel 72 of the detergent box 71 extends toward the side where the pulling mechanism 32 is located. When the detergent box 71 is closed, the front decorative panel 72 of the detergent box 71 covers the pulling mechanism 32.

[0286] In this embodiment, only one interlocking groove is required on the panel, and the shape of the interlocking groove is adapted to the shape of the front decorative panel 72. The pull-out opening of the pull-out portion 322 and the pull-out opening of the detergent box 71 are both set in the interlocking groove, so that there are only the front decorative panel 72 area and the main control panel area on the panel, which further improves the aesthetics of the panel.

[0287] In this embodiment, the pulling portion 322 of the pulling mechanism 32 can be pulled out synchronously with the detergent box 71 , or can be pulled out independently of the detergent box 71 .

[0288] Specifically, the synchronous pulling of the pulling portion 322 and the detergent box 71 is achieved as follows:

[0289] The pull-out portion 322 has the same pulling direction as the detergent box 71. The front end of the pull-out portion 322 is connected to the front decorative panel 72 of the detergent box 71. When the user pulls the detergent box 71, the front decorative panel 72 drives the pull-out portion 322 to be pulled synchronously through the connection structure between the front end of the pull-out portion 322, and the filter 31 is pulled out synchronously.

[0290] By connecting the front end of the pull-out portion 322 to the front decorative panel 72 of the detergent box 71, the pull-out mechanism 32 and the detergent box 71 can be pulled out synchronously, so that the user can check the condition of the filter 31 every time when adding detergent. The user can promptly discover any problems with the filter 31, clean and maintain the filter 31 in time, and ensure the working stability of the filter 31.

[0291] Of course, in this embodiment, another connection structure may be provided between the drawer portion 322 and the detergent box 71 , as long as the detergent box 71 and the drawer portion 322 can be drawn synchronously.

[0292] Preferably, in this embodiment, for the implementation mode in which the detergent box 71 and the drawing portion 322 are synchronously drawn, the drawing mechanism 32 is provided on the left side or the right side of the detergent box 71 .

[0293] In this embodiment, the pull-out portion 322 is pulled out independently of the detergent box 71 in the following manner:

[0294] The front end of the pull-out portion 322 is spaced apart from the front decorative panel 72 of the detergent box 71 and no connecting structure is provided. After the detergent box 71 is pulled out, the front end of the pull-out portion 322 covered by the front decorative panel 72 is exposed. At this time, the user can pull out the filter 31 through the pull-out portion 322.

[0295] In the above arrangement, the length of the pulling path of the pulling portion 322 is less than or equal to the length of the pulling path of the detergent box 71 to ensure that the filter 31 can be pulled out.

[0296] Preferably, in this embodiment, during the pulling process of the detergent box 71 , the front decorative plate 72 of the detergent box 71 can avoid the pulling path of the pulling portion 322 , thereby ensuring that the pulling portion 322 has a sufficient pulling path to pull the filter 31 .

[0361] In this embodiment, a lint filter assembly 3 for filtering lint in the drying air flow is provided in the air duct 21 . The lint filter assembly 3 includes a filter screen 31 provided in the air duct 21 .

[0362] During daily use, after the user operates the clothes processing machine to run the drying function several times, some lint will gather on the filter 31. In order to ensure the stability of the drying effect, the user needs to remove the filter 31 and clean it.

[0363] In order to improve the intelligence level of the clothes processing machine and enhance the user experience, in the embodiment of the present invention, a filter cleaning structure 4 for cleaning the filter 31 is provided in the air duct 21 .

[0364] Specifically, as shown in Figures 5, 6, and 21 to 25, the filter cleaning structure 4 includes an electric scraper 41 and a spray device 42. The electric scraper 41 is used to scrape and collect the hair debris on the filter 31, and the spray device 42 is used to flush the hair debris collected on the filter 31, thereby cleaning the hair debris out of the air duct 21.

[0365] In this embodiment, the air duct 21 is configured as a flat pipe with a rectangular cross-section, and the filter 31 is configured in the air duct 21 so as to be pullable from the front end of the air duct 21 to cover the cross-section of the air duct 21 and filter the drying airflow passing therethrough.

[0366] The electric scraper 41 includes a scraper body and a driver for driving the scraper body to reciprocate.

[0367] In this embodiment, the scraper body is disposed along the width of the filter 31, and the side of the scraper body proximate to the filter 31 elastically abuts against the filter 31. Specifically, the scraper body includes a sliding seat and a flexible portion disposed on the sliding seat.

[0388] Preferably, in this embodiment, two adjacent rows of spray ports are staggered in the circumferential direction of the first spray pipe 421 .

The water flow of the second spray pipe 422 flushes the hair scraps remaining at the corners of the air inlet end of the air duct 21 and on the inner wall of the port at the air inlet end of the air duct 21, which can ensure that all the hair scraps cleaned from the filter 31 are cleared out.

[0396] In this embodiment, the laundry machine is provided with a water box 7, the detergent box 71 is pullable and arranged in the water box 7, a water separation tray is provided on the water box 7, and the first spray pipe 421 and the second spray pipe 422 are connected to the water separation tray of the water box 7.

[0397] Preferably, in this embodiment, the first spray pipe 421 and the second spray pipe 422 are supplied with water through the same water supply pipe.

Preferably, the diverter device can be a tee.

[0398] The present invention also discloses a control method for the aforementioned laundry machine. Specifically, the laundry machine includes a washing program and a drying program. When the laundry machine is running the drying program, if the filter 31 is detected to be clogged, the electric scraper 41 can be controlled to scrape the lint on the filter 31 and gather it on the side of the filter 31 to ensure the smooth running of the drying program. Then, when the laundry machine is running the washing program, the spray device 42 is operated to flush the accumulated lint into the drum module 1 and discharge it through the laundry machine's drainage pipe.

[0399] Preferably, in this embodiment, the hair scraps accumulated on the filter screen 31 are flushed during the washing and drainage stage, and the hair scraps are flushed into the outer drum of the drum module 1 and discharged through the drainage pipe.

[0403] The flow rate of the spray device 42 is controlled according to the water level in the outer tube so that the water level in the outer tube is lower than the bottom of the inner tube.

[0404] In this embodiment, by detecting the water level in the outer drum and adjusting the flow rate of the spray device 42 according to the water level in the outer drum, the water level of the spray water for flushing the lint can always be lower than the bottom of the inner drum, thereby preventing the lint from sticking to the clothes and ensuring the cleaning effect of the clothes.

[0406] Example 7

[0407] In an embodiment of the present invention, a drying system 2 is introduced.

[0408] A lint filter assembly 3 for filtering lint in the drying air flow is provided in the air duct 21 of the drying system 2 . The lint filter assembly 3 includes a filter screen 31 and a sedimentation section 213 provided in the air duct 21 .

[0409] As shown in FIG. 1 to FIG. 4 , the difference between this embodiment and the drying system in the above-mentioned embodiments 1 to 6 is that a settling section is added to the air duct.

[0410] Specifically, the air duct 21 includes a settling section 213, which constitutes the air inlet end of the air duct 21. The settling section 213 extends from bottom to top. The lower end of the settling section 213 is provided with an air inlet 2137 for the air duct 21, and the upper end of the settling section 213 is provided with a condensate inlet 2136 for introducing condensate. The filter 31 is disposed in the air duct 21 downstream of the settling section 213 along the airflow direction.

[0411] In this embodiment, condensed water is introduced into the settling section 213 from the condensed water inlet 2136, causing the hot and humid dry air flow blown into the air duct 21 to first flow through the settling section 213, where it comes into contact with the condensed water in the settling section 213 for heat exchange. The condensed water condenses the hot and humid dry air flow, and at the same time, the lint and water droplets carried in the dry air flow condense and settle, achieving a primary filtration of the dry air flow. The dry air flow then flows through the filter 31, which performs a secondary filtration of the dry air flow, thereby ensuring the filtration effect of the lint in the dry air flow. Moreover, the filter 31 downstream of the settling section 213 only needs to filter the lint remaining in the dry air flow, which can reduce the accumulation rate of lint on the filter 31, thereby reducing the frequency of cleaning of the filter 31 by the user.

[0412] In this embodiment, in the initial and middle stages of the drying, the humidity of the drying airflow in the air duct 21 is relatively high, and the amount of condensed water generated during the drying process is also relatively large. Therefore, the sedimentation section 213 is used to condense, sediment and filter the drying airflow flowing into the air duct 21, which can achieve good condensation and sedimentation effects. When the drying process reaches the middle and late stages, the humidity of the drying airflow is low, and the amount of condensed water condensed on the condensation structure 5 becomes less, so that the sedimentation section 213 has a poor sedimentation effect on the lint. Therefore, the filter 31 is used to filter the drying air in the middle and late stages of the drying process, which can make up for the shortcomings of the sedimentation section 213 and ensure the filtering effect of the drying airflow.

[0413] As shown in Figure 2, in this embodiment, the lower end of the sedimentation section 213 is closed, and includes a first guide wall 2131 and a second guide wall 2132 extending from bottom to top and arranged opposite to each other. Guide side walls are also provided on the left and right sides of the first guide wall 2131 and the second guide wall 2132. The first guide wall 2131, the second guide wall 2132 and the guide side walls on the left and right sides surround the sedimentation section 213 of the air duct 21.

[0414] The lower end of the settling section 213 is closed. The air inlet 2137 of the air duct 21 is located at the bottom of the first guide wall 2131, opposite the bottom of the second guide wall 2132. The condensed water inlet 2136 is located above the second guide wall 2132, corresponding to the upper end of the second guide wall 2132. Thus, the condensed water is introduced from the upper end of the second guide wall 2132 and flows along the second guide wall 2132. The drying airflow is blown in from the air inlet 2137 at the bottom of the first guide wall 2131, blows onto the second guide wall 2132, and then flows upward through the guides of the second guide wall 2132 and the first guide wall 2131. The drying airflow is blown onto the second guide wall 2132 and can come into contact with the condensed water on the second guide wall 2132. Then, as the drying airflow flows upward along the sedimentation section 213, it will also come into contact with the condensed water on the second guide wall 2132. The condensed water condenses the hot and humid drying airflow, and the lint and water droplets carried in the drying airflow condense and settle.

[0415] Preferably, the extension direction of the air inlet 2137 of the air duct 21 is perpendicular to the bottom of the second guide wall 2132 .

[0416] As shown in FIG3 and FIG4 , in some specific embodiments, the hollow chamber inside the settling section 213 is introduced in detail.

[0417] In this embodiment, a water retaining structure 213-1 is provided on the side wall of the hollow chamber. When the condensed water flowing into the hollow chamber flows to the water retaining structure 213-1, it is broken up into a water splash. The water splash can not only flush the side wall of the hollow chamber while the drying process is in progress, but also dissolve the lint in the circulating airflow in the water splash. The lint then flows out of the air inlet 2137 with the condensed water and is finally discharged from the machine through the drain pipe. The water retaining structure 213-1 can be a water retaining rib, a water retaining block, or a water retaining plate. Such adjustments and changes to the specific structural form of the water retaining structure 213-1 do not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention.

[0418] A first arc-shaped structure, a second arc-shaped structure and a diversion structure 213-4 located between the first arc-shaped structure and the second arc-shaped structure are arranged on the second guide wall 2132. The left guide side wall and the right guide side wall of the hollow chamber, that is, the guide side walls on both sides of the first guide wall 2131 and the second guide wall 2132, are both arranged to be arc-shaped. The two ends of the left guide side wall are smoothly connected to the first arc-shaped structure and the left end of the first guide side wall respectively, and the two ends of the right guide side wall are smoothly connected to the second arc-shaped structure and the right end of the first guide side wall respectively.

[0419] The air inlet 2137 is arranged on the first guide side wall of the hollow chamber, and the diverter structure 213-4 is opposite to the air inlet 2137. Through such an arrangement, the gas entering from the air inlet 2137 can just hit the diverter structure 213-4, and the diverter structure 213-4 can divide the airflow into two airflows, recorded as the first airflow 213-2 and the second airflow 213-3, and can make the first airflow 213-2 enter the first arc structure roughly along the tangential direction of the first arc structure. Under the impetus of the subsequent airflow, the first airflow 213-2 can rotate counterclockwise and rise along the first arc structure, the left guide side wall and the left part of the first guide side wall, and can make the second airflow 213-3 enter the second arc structure roughly along the tangential direction of the second arc structure. Under the impetus of the subsequent airflow, the second airflow 213-3 can rotate clockwise and rise along the second arc structure, the right guide side wall and the right part of the first guide side wall.

[0420] The hollow chamber includes two gas channels. The first arc-shaped structure, the left guide side wall and the left part of the first guide side wall constitute the first gas channel. The second arc-shaped structure, the right guide side wall and the right part of the first guide side wall constitute the second gas channel. After the gas enters the hollow chamber from the air inlet 2137, it is divided into a first airflow 213-2 and a second airflow 213-3 by the diversion structure 213-4. The first airflow 213-2 can rotate and rise along the inner wall of the first gas channel, and the second airflow 213-3 can rotate and rise along the inner wall of the second gas channel.

[0421] The sedimentation section 213 of the present invention creatively provides a diversion structure 213-4 on the second guide side wall of the hollow chamber, and the diversion structure 213-4 divides the gas entering from the air inlet 2137 into a first airflow 213-2 and a second airflow 213-3, so that the first airflow 213-2 and the second airflow 213-3 respectively rotate and rise. By rotating and rising the first airflow 213-2 and the second airflow 213-3, the distances of the first airflow 213-2 and the second airflow 213-3 in the sedimentation section 213 become longer, thereby improving the cooling effect.

[0422] In addition, two rotating upward air flows carry the broken up condensed water splashes, forming "cyclone" shaped water splashes in the sedimentation section 213. By controlling the amount of condensed water, a vortex-shaped water splash with a certain liquid level height is formed in the sedimentation section 213. When the air flow passes through here, the lint is dissolved in the water splash. At the same time, at the air inlet 2137 where lint accumulation is most likely to form, the constantly fluctuating water splashes are used to flush the bottom of the sedimentation section 213 in real time, thereby improving the filtering effect on lint. After the program runs stably, the amount of condensed water entering and leaving the sedimentation section 213 reaches a dynamic balance.

[0423] The water retaining structure 213-1 is disposed close to the diversion structure 213-4. By disposing the water retaining structure 213-1 close to the diversion structure 213-4, the condensed water can meet the two spiral airflows immediately after being dispersed, thereby achieving a better effect of filtering lint and condensing.

[0424] Preferably, in this embodiment, the condensate inlet 2136 corresponds to the air inlet 2137 of the air duct 21 in the vertical direction.

[0425] Preferably, in this embodiment, the width of the settling section 213 gradually decreases from top to bottom, and the width of the lower end of the settling section 213 is adapted to the width of the air inlet 2137 of the air duct 21. Specifically, the distance between the guide side walls on the left and right sides of the first guide wall 2131 and the second guide wall 2132 gradually decreases from top to bottom.
