Description

Technical Field

[0001] The present invention relates to the technical field of clothing treatment, and particularly relates to a lifting rib, a cylinder assembly and a clothing treatment device. Background Art

[0002] In existing clothing treatment equipment, such as a drum washing machine, a filtering device for collecting lint is usually installed in front of a drainage pump to prevent the drainage pump from being blocked by lint during drainage. In this way, lint can only be collected during drainage. The drainage is discharged from the bottom of the drum washing machine, and the lint floating in the water above the clothes remains on the clothes and cannot be removed.

[0003] Lifting ribs are usually provided on the inner wall of the inner drum in a drum washing machine. During the continuous rotation of the inner drum, the lifting ribs prevent the clothes from slipping along the drum and drive the clothes to turn up and down, with a single function. In existing drum washing machines, there is an integration of the lifting ribs and a lint filter, so that the lifting ribs have a lint filtering function. However, the filter screen usually covers the water outlet of the lifting ribs. When there is a lot of lint accumulated on the filter screen, the water outlet will be blocked, resulting in the failure of filtering. Summary of the Invention

[0004] The purpose of the present invention is to provide a lifting rib, a cylinder assembly and a clothing treatment device to solve the technical problem that the lint accumulated on the filter screen in the prior art is likely to block the water outlet.

[0005] With the above concept, the technical solution adopted by the present invention is as follows:

[0006] A lifting rib, comprising:

[0007] A lifting rib body, a collection cavity for collecting lint is defined in the lifting rib body, and a water inlet and a water outlet communicating with the collection cavity are formed on the lifting rib body;

[0008] A one-way conduction member, which is arranged in the collection cavity and at the water inlet, and the one-way conduction member is adapted to conduct the one-way conduction between the water inlet and the collection cavity when water flows from the outside through the water inlet into the collection cavity;

[0009] A filtering member, which is arranged in the collection cavity and on the water outlet path, the filtering member is spaced from the water outlet, and the filtering member includes a guiding portion, and the guiding portion protrudes in a direction away from the water outlet to guide the lint to flow along the filtering member to the periphery of the guiding portion.

[0010] Wherein, an installation cavity is formed on one side of the collection cavity close to the water outlet, the installation cavity has an installation opening communicating with the collection cavity, the filtering member is arranged to be inserted into the installation cavity from the installation opening, and the guiding portion protrudes from the installation opening into the collection cavity.

[0011] Wherein, in the direction from the installation port to the water outlet, the cross-sectional area of the installation cavity gradually increases.

[0012] Wherein, positioning bosses are arranged at both ends of the filter element in the installation cavity. An installation gap is formed between the positioning bosses and the inner wall of the installation cavity. At least part of the filter element is inserted into the installation gap, and the positioning bosses seal the ends of the filter element.

[0013] Wherein, water inlets are formed on both the left side and the right side of the lifting rib body. The one-way conduction member includes a support portion and two groups of flexible portions arranged at intervals on the support portion. The support portion can slide along the left-right direction of the lifting rib body. When one group of the two groups of flexible portions opens the water inlet on one side, the other group closes the water inlet on the other side.

[0014] Wherein, the flexible portion includes a flexible disc, and the flexible disc is recessed in a direction away from the water inlet to form a water collecting cavity.

[0015] A cylinder assembly, comprising:

[0016] An outer cylinder;

[0017] An inner cylinder, arranged in the outer cylinder. A containing space is formed between the inner cylinder and the outer cylinder. Water passing holes communicating with the containing space are formed on the inner cylinder.

[0018] The lifting rib as described above, and the lifting rib is arranged on the inner wall of the inner cylinder.

[0019] Wherein, a water permeable component is arranged at the bottom of the lifting rib body, and the water permeable component is configured to allow the water in the collection cavity to permeate under the action of centrifugal force when the inner cylinder rotates.

[0020] Wherein, a stud component is arranged at the bottom of the lifting rib body. An installation hole and a guiding groove communicating with the installation hole are formed on the inner cylinder. The stud component is configured to be inserted into the installation hole and can slide into the guiding groove to be clamped with the inner cylinder.

[0021] A laundry treatment device, comprising a machine shell and the cylinder assembly as described above, and the outer cylinder is arranged in the machine shell.

[0022] Advantages of the present invention:

[0023] For the lifting rib proposed by the present invention, when water flow enters the collection chamber from the water inlet, the one-way conduction member conducts unidirectionally between the water inlet and the collection chamber, so that water can only enter the water inlet and cannot flow out. The filtering member is located on the water outlet path, and the water flow in the collection chamber flows out from the water outlet after passing through the filtering member. The filtering member intercepts the thread debris in the water flow in the collection chamber. The filtering member is spaced from the water outlet. Since the guiding portion of the filtering member protrudes away from the water outlet to guide the thread debris to flow along the filtering member towards the periphery of the guiding portion, the thread debris will not accumulate at the guiding portion, thus ensuring the smoothness of the water outlet.

[0054] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0055] Embodiment 1

[0056] Refer to Figures 1 to 11 , the present invention provides a laundry treatment device, which can be a washing machine, a dryer, or a washer-dryer combination. The laundry treatment device includes a housing 100 and a drum assembly. The drum assembly includes an outer drum and an inner drum 200. The outer drum is disposed inside the housing 100, and the inner drum 200 is disposed inside the outer drum. A receiving space is formed between the inner drum 200 and the outer drum, and a water passing hole 210 communicating with the receiving space is formed on the inner drum 200. The laundry is placed in the inner drum 200. During washing and dehydration, the inner drum 200 rotates around its own first axis. During dehydration, under the action of centrifugal force, the water on the laundry passes through the water passing hole 210 and enters the receiving space and is discharged from the outer drum.

[0057] The inner drum 200 has a laundry access opening, and the laundry treatment device further includes a door body 400. The door body 400 is disposed on the housing 100 and is used to open and close the laundry access opening. It is defined that the first axis extends in the front-rear direction, and the laundry access opening is located on the front side of the inner drum 200. The drum assembly further includes a lifter 300, and the lifter 300 is disposed on the inner wall of the inner drum 200. Usually, after the lifter 300 is installed on the inner drum 200, the lifter 300 extends along the front-rear direction of the inner drum 200. The structure of the lifter 300 will be introduced in detail below.

[0058] The lifting rib 300 includes a lifting rib body 310, a one-way conduction member 320, and a filtering member 330. A collection cavity 311 for collecting lint is defined within the lifting rib body 310. An inlet 312 and an outlet 313 that communicate with the collection cavity 311 are formed on the lifting rib body 310. The one-way conduction member 320 is disposed within the collection cavity 311 and at the inlet 312. The one-way conduction member 320 is adapted to conduct unidirectionally between the inlet 312 and the collection cavity 311 when water flows from the outside through the inlet 312 into the collection cavity 311. The filtering member 330 is disposed within the collection cavity 311 and on the water outlet path. The filtering member 330 is spaced apart from the outlet 313. When the water flow within the collection cavity 311 flows toward the outlet 313, it passes through the filtering member 330 for filtration, such that the lint is intercepted within the collection cavity 311. The guiding portion 331 protrudes in a direction away from the outlet 313 to guide the lint to flow along the filtering member 330 toward the periphery of the guiding portion 331, so that the lint does not accumulate at the guiding portion 331, thereby ensuring the smoothness of the outlet 313.

[0059] It is defined that the lifting rib body 310 extends along a first straight line direction. Along a direction perpendicular to the first straight line direction, the cross-sectional shape of the collection cavity 311 is trapezoidal or quasi-trapezoidal. Usually, after the lifting rib 300 is installed on the inner cylinder 200, the first straight line is parallel to the first axis.

[0060] The filtering member 330 and the lifting rib body 310 can be connected by fasteners, such as screws. In this embodiment, the filtering member 330 is inserted into the lifting rib body 310, which is convenient for installation and disassembly. Specifically, an installation cavity 314 is formed on one side within the collection cavity 311 close to the outlet 313. The installation cavity 314 has an installation opening 3141 that communicates with the collection cavity 311. The filtering member 330 is arranged to be inserted into the installation cavity 314 from the installation opening 3141, and the guiding portion 331 protrudes from the installation opening 3141 into the collection cavity 311.

[0061] During installation, the filtering member 330 can be inserted into the installation cavity 314 from the installation opening 3141. The filtering member 330 can be a filter net. Since the filter net itself has a certain elasticity, when inserted into the installation opening 3141, the filter net is squeezed and deformed. After entering the installation cavity 314, the filter net unfolds under its own elastic force and then fits against the inner wall of the installation cavity 314, and will not fall off from the installation opening 3141. No other fixing methods are required, which is convenient for installation and disassembly. The guiding portion 331 of the filtering member 330 protrudes from the installation opening 3141, which is convenient for guiding the lint.

[0062] In the direction from the installation opening 3141 to the water outlet 313, the cross-sectional area of the installation cavity 314 gradually increases, which facilitates the unfolding of the filter element 330 after it enters the installation cavity 314, and also makes the distance between the filter element 330 and the water outlet 313 relatively far. It can be understood that the installation cavity 314 extends along the length direction of the lifting rib body 310, and is used to install and limit the movement of the filter element 330. The shape of the installation cavity 314 is adapted to the shape of the filter element 330. The lifting rib body 310 extends along the first straight line direction. Along the direction perpendicular to the first straight line direction, the cross-sectional shape of the filter element 330 is arc-shaped or triangular. The filter element 330 can also be prismatic. In this embodiment, the cross-sectional shape of the filter element 330 is arc-shaped, and the installation cavity 314 is semi-circular, which facilitates the filter element 330 to share the water pressure when filtering water.

[0063] Positioning bosses 315 are arranged at both ends of the filter element 330 in the installation cavity 314. An installation slot 3151 is formed between the positioning bosses 315 and the inner wall of the installation cavity 314. At least part of the filter element 330 is inserted into the installation slot 3151, and the positioning bosses 315 block the ends of the filter element 330. The filter element 330 is inserted into the installation slot 3151 from the installation opening 3141. On the one hand, the installation slot 3151 plays a role in limiting the filter element 330 to prevent the filter element 330 from falling off; on the other hand, the setting of the positioning bosses 315 blocks both ends of the filter element 330, which can prevent lint from overflowing.

[0064] The filter element 330 can be provided with one layer or multiple layers, as long as the guiding portion 331 can guide the lint, and the filter element 330 is spaced apart from the water outlet 313 by a certain distance, so as to separate the lint and efficiently drain the water.

[0065] Define the side of the lifting rib body 310 close to the inner wall of the inner cylinder 200 as the bottom, and the side far from the inner wall of the inner cylinder 200 as the top. The lifting rib body 310 also includes the left side, right side, front side and rear side arranged between the top and the bottom.

[0066] In this embodiment, water inlets 312 are provided on both the left side and the right side of the lifting rib body 310, and the water outlet 313 is arranged at the top of the lifting rib body 310. During the rotation of the inner cylinder 200, when the lifting rib 300 rotates with the inner cylinder 200 to a lower position, water enters the collection cavity 311 from the water inlets 312 and accumulates in the collection cavity 311. The excess water is filtered by the filter element 330 and then flows out from the water outlet 313 arranged at the top, and the lint remains in the collection cavity 311. An appropriate amount of water accumulates inside the collection cavity 311. When the lifting rib 300 rotates with the inner cylinder 200 to a higher position, the water inside the collection cavity 311 is discharged from the water outlet 313, and the water flow hammers the clothes from top to bottom, forming a water curtain spraying effect, which improves the washing and cleaning ability.

[0067] The cross-sectional shape of the water outlet 313 is oval, circular or polygonal. Along the water outlet direction, the cross-sectional area of the water outlet 313 gradually decreases, which is convenient for water collection. In this way, even if the water stored inside the collection cavity 311 becomes less, a concentrated water flow can be formed instead of scattered water droplets, improving the impact force of the water flow on the clothes. The water outlet 313 includes a plurality of water outlet holes, and the plurality of water outlet holes are arranged at intervals in the front-rear direction.

[0068] The water inlets 312 are arranged on the left and right sides of the lifting rib body 310 close to the bottom of the lifting rib body 310. Specifically, a vertical wall 3111 perpendicular to the bottom is provided at the bottom of the inner side wall of the collection cavity 311, and the water inlet 312 is opened on the vertical wall 3111 so as to be sealed by the one-way conduction member 320 even when the one-way conduction member 320 rotates.

[0069] In this embodiment, the one-way conduction member 320 includes a support portion 321 and two groups of flexible portions 322 arranged at intervals on the support portion 321. The support portion 321 can slide along the left-right direction of the lifting rib body 310. When one of the two groups of flexible portions 322 opens the water inlet 312 on one side, the other group closes the water inlet 312 on the other side. When the water inlet 312 on the left side intakes water, under the impact of the water flow, the support portion 321 and the flexible portions 322 slide to the right, so that the water inlet 312 on the left side is opened, and the flexible portion 322 on the right side seals the water inlet 312 on the right side. When the water inlet 312 on the right side intakes water, under the impact of the water flow, the support portion 321 and the flexible portions 322 slide to the left, so that the water inlet 312 on the right side is opened, and the flexible portion 322 on the left side seals the water inlet 312 on the left side.

[0070] The flexible portion 322 includes a flexible disk. The flexible disk is in a disk shape and can be made of soft heat-resistant materials such as rubber or silica gel. The flexible disk is not a flat disk structure, but the flexible disk is recessed in the direction away from the water inlet 312 to form a water collection cavity. When sealing, the flexible disk can be deformed and can fit the vertical wall 3111 of the collection cavity 311 under the action of the water flow, and the sealing effect is better; the flexible disk can also play a role in holding water. The water collection cavity can collect more water to push the one-way conduction member 320 to move. Compared with the flat disk structure, the water collection cavity can hold water to generate a greater force. In this way, the one-way conduction member 320 responds quickly. As long as the water inlet 312 on one side intakes water, the water inlet 312 on the other side can be immediately blocked to prevent water from flowing out.

[0071] The water inlet 312 includes a plurality of water inlet holes, and the plurality of water inlet holes are arranged at intervals in the front-rear direction. Among the two groups of flexible portions 322, one group is used to seal the water inlet holes on the left side, and the other group is used to seal the water inlet holes on the right side. It can be understood that a flexible disk is provided for each water inlet hole. Therefore, each group of flexible portions 322 includes a plurality of flexible disks.

[0072] The support portion 321 includes support columns, and the flexible disk is connected to the support columns. In this embodiment, the water inlet holes on the left side of the lifting rib body 310 and the water inlet holes on the right side are in one-to-one correspondence and coaxially arranged. Two relatively arranged water inlet holes share one support column. Therefore, the support columns extend linearly. Multiple support columns can be provided, and two flexible disks are provided on each support column. Each support column can be independently arranged, or each support column can be connected as a whole. In other embodiments, the water inlet holes on the left side of the lifting rib body 310 and the water inlet holes on the right side can be arranged in a staggered manner, and the support columns can extend in a bent manner, as long as it is ensured that the flexible disks can correspond to the water inlet holes one by one.

[0073] In some embodiments, a one-way valve can be provided at the water outlet 313. The one-way valve is adapted to unidirectionally conduct the water outlet 313 and the outside when the water flows from the collection chamber 311 to the outside. The one-way valve can be a conventional ball valve. There is also an advantage in providing a one-way valve at the water outlet 313, that is, when the lifting rib 300 rotates with the inner cylinder 200 to a lower position, the water in the inner cylinder 200 will not enter the collection chamber 311 from the water outlet 313, so as to ensure the filtering function of the collection chamber 311.

[0074] A water permeable component 340 is provided at the bottom of the lifting rib body 310. The water permeable component 340 is arranged to allow the water in the collection chamber 311 to permeate under the action of centrifugal force when the inner cylinder 200 rotates. The permeated water is discharged through the water passing holes 210 on the inner cylinder 200. This enables the water accumulated inside the lint to be discharged under the action of centrifugal force, that is, to dehydrate the lint, avoiding uneven weight caused by excessive water accumulation in the lint, which may cause abnormal vibration of the washing machine, and also preventing the growth of bacteria and generation of odors due to the presence of water in the lint.

[0075] It can be understood that the water permeable component 340 allows the water in the collection chamber 311 to permeate, but the lint will still remain in the collection chamber 311. In some embodiments, the water permeable component 340 includes a flip plate hinged to the lifting rib body 310. The flip plate is opened under the action of centrifugal force against the elastic force of the torsion spring. In order to prevent the lint from overflowing, a filter net is provided at the position corresponding to the flip plate in the collection chamber 311, so that the water permeable component 340 only allows water to pass through and no lint will overflow.

[0076] In this embodiment, the water permeable component 340 includes a flexible plate 341. Cut slits 342 are formed on the flexible plate 341. The cut slits 342 divide the flexible plate 341 into at least two wall flaps. Since the flexible plate 341 is made of silicone or rubber and has elasticity, after the cut slits 342 are provided, the structures on both sides of the cut slits 342 will still squeeze each other. When static, the wall flaps are closed and do not leak water. When subjected to a large centrifugal force, the wall flaps will move away from each other, exposing a gap through which water can flow out. The cut slits 342 are relatively small, and basically no lint will overflow.

[0077] In this embodiment, the slit 342 is in a cross shape, and the slit 342 divides the flexible plate 341 into four wall flaps. To facilitate the opening of the wall flaps, the thickness of the flexible plate 341 gradually decreases from the periphery of the flexible plate 341 towards the middle. Specifically, a pit 343 can be formed on the bottom surface or the top surface of the flexible plate 341 to change the wall thickness of the flexible plate 341, making it easier to open the slit 342 during dehydration.

[0078] Part of the water passing holes 210 on the upper part of the inner cylinder 200 are arranged opposite to the lifting rib body 310, so that the water accumulated in the lint collected in the collection cavity 311 can be smoothly thrown out. To prevent the bottom wall of the lifting rib body 310 from closely adhering to the inner cylinder 200 and the water permeable component 340 not being aligned with the water passing holes 210 of the inner cylinder 200, resulting in drainage failure, a convex rib 318 is provided at the bottom of the lifting rib body 310. The convex rib 318 protrudes outward to facilitate abutting against the inner cylinder 200, so that there is a gap between the water permeable component 340 and the inner cylinder 200, facilitating the opening of the water permeable component 340. The convex rib 318 can be arranged in strips or distributed in dots.

[0079] To install the various components inside the lifting rib body 310, the lifting rib body 310 is set as a split structure. Specifically, the lifting rib body 310 includes a body part 316 and a bottom plate 317. The body part 316 and the bottom plate 317 enclose a collection cavity 311, and the bottom plate 317 is arranged at the bottom of the body part 316. The water inlet 312 and the water outlet 313 are arranged on the body part 316, and the water permeable component 340 and the convex rib 318 are arranged on the bottom plate 317.

[0080] The bottom plate 317 and the body part 316 can be snap-connected. Specifically, an opening is formed at the bottom of the body part 316, and the bottom plate 317 can be snapped into the opening. To facilitate installation and limit the position of the bottom plate 317, the opening at the bottom of the body part 316 is in a stepped shape. After the lifting rib 300 is installed on the inner cylinder 200, the bottom plate 317 is pressed against the bottom of the body part 316, and the convex rib 318 abuts against the inner cylinder 200, so that the bottom plate 317 will not shift.

[0081] The lifting rib 300 is detachably connected to the inner cylinder 200 to regularly clean the lint inside the lifting rib 300. Specifically, the lifting rib body 310 is connected to the inner cylinder 200. It can be connected by fasteners, such as screws. In this embodiment, the lifting rib body 310 is snap-connected to the inner cylinder 200, which is convenient for installation and disassembly.

[0082] Specifically, a nail clamping component 350 is provided at the bottom of the lifting rib body 310. An installation hole 220 and a guiding groove 230 communicating with the installation hole 220 are formed on the inner cylinder 200. The nail clamping component 350 is set to be inserted into the installation hole 220 and can slide into the guiding groove 230 to be snap-connected to the inner cylinder 200.

[0083] The staple assembly 350 includes a screw 351, a spring 352, and a guide cap 353. The screw 351 includes a screw rod and a nut. The guide cap 353 is sleeved on the screw rod. The spring 352 is sleeved on the screw rod and is located between the nut and the guide cap 353. The guide cap 353 has a guide surface that protrudes away from the spring 352. The screw rod is threadedly connected to the bottom of the lifting rib body 310. Before installing the lifting rib 300 on the inner cylinder 200, the screw rod is first threadedly connected to the lifting rib body 310. When installing the lifting rib 300 on the inner cylinder 200, the lifting rib body 310 is located inside the inner cylinder 200, the guide cap 353 is located outside the inner cylinder 200, and the spring 352 is used to tightly press the guide cap 353 against the outer wall of the inner cylinder 200, so that the lifting rib body 310 is tightly pressed against the inner cylinder 200.

[0084] The size of the installation hole 220 is convenient for the larger one of the nut and the guide cap 353 to pass through. The guide groove 230 only allows the screw rod to pass through. Therefore, during installation, the nut, the guide cap 353, and the spring 352 in the staple assembly 350 are passed through the installation hole 220 to the outside of the inner cylinder 200. When sliding along the guide groove 230, the nut, the guide cap 353, and the spring 352 all slide outside the inner cylinder 200. The guide cap 353 is a spherical shell or a part similar to a spherical shell to form a guide surface. There is a through hole in the center of the guide cap 353 for the screw rod to pass through.

[0085] An elastic member 360 is provided at the bottom of the lifting rib body 310. A limiting hole 240 is formed at one end of the guide groove 230 away from the installation hole 220. A limiting portion 250 is provided on the extending path of the guide groove 230. The staple assembly 350 is arranged to be inserted from the installation hole 220 and can slide along the guide groove 230 into the limiting hole 240. The elastic member 360 can be tightly pressed against the limiting portion 250. During installation, the staple assembly 350 is inserted into the installation hole 220. At this time, the elastic member 360 is spaced from the limiting portion 250 by a certain distance. The lifting rib body 310 is slid along the guide groove 230, so that the staple assembly 350 slides along the guide groove 230. During the sliding process, the elastic member 360 abuts against the limiting portion 250 until the staple assembly 350 slides into the limiting hole 240. The lifting rib body 310 is released. Under the action of the elastic member 360, the staple assembly 350 is tightly pressed against the limiting hole 240. During disassembly, just slide in the opposite direction, and the installation and disassembly are convenient.

[0086] In this embodiment, the guide groove 230 extends in a U shape. The installation hole 220 and the limiting hole 240 are located at two ends of the guide groove 230. The limiting portion 250 is provided at the bending portion of the guide groove 230. Specifically, the guide groove 230 includes two vertically arranged grooves spaced apart and a horizontal groove located between the two vertical grooves. Among them, the vertical grooves extend parallel to the first axis of the inner cylinder 200, and the horizontal groove extends circumferentially around the inner cylinder 200.

[0087] During installation, the operator places the lifting rib 300 at the corresponding position of the inner cylinder 200, aligns one of the staple components 350 with the mounting hole 220 and inserts it. Then, the operator moves the lifting rib 300 to ensure that the other staple components 350 also enter the mounting hole 220. At this time, the elastic member 360 and the limiting portion 250 are arranged at intervals. Press the lifting rib body 310 downward to the bottom, and then slide it along the guiding groove 230 so that the guiding cap 353 is located outside the inner cylinder 200. During the sliding process, the elastic member 360 abuts against the limiting portion 250. Continue to slide until the staple component 350 is located in the limiting hole 240. After releasing the hand, under the action of the elastic member 360, the staple component 350 abuts tightly against the limiting hole 240, and the elastic member 360 abuts tightly against the limiting portion 250.

[0088] The limiting portion 250 is a flange provided on the inner wall of the inner cylinder 200, which is convenient for abutting against the elastic member 360 to fix the lifting rib 300. The elastic member 360 extends along the front-back direction of the lifting rib body 310. After the elastic member 360 abuts against the limiting portion 250, the elastic force of the elastic member 360 causes the staple component 350 to abut tightly against the limiting hole 240. Since the lifting rib 300 bears lateral force during operation and hardly bears axial force, it is almost impossible to fall off without human operation.

[0089] The lifting rib body 310 further includes reinforcing portions 319 provided at the front and rear ends of the body portion 316. The reinforcing portions 319 and the body portion 316 enclose a receiving space 3191. The elastic member 360 is arranged in the receiving space 3191. The reinforcing portion 319 has the advantages of small space, large structural stiffness and large wall thickness, which is convenient for installing the staple component 350. The staple component 350 can be threadedly connected to the bottom of the reinforcing portion 319. The reinforcing portion 319 and the body portion 316 can be integrally formed.

[0090] In this embodiment, four groups of staple components 350 are provided, four elastic members 360 are provided, and four mounting holes 220, four guiding grooves 230, four limiting holes 240 and four limiting portions 250 are correspondingly provided on the inner cylinder 200.

[0091] When the lifting rib 300 needs to be cleaned, slide the lifting rib 300 along the guiding groove 230 until the staple component 350 is located in the mounting hole 220, remove the lifting rib 300, and disassemble the bottom plate 317. Then, the lint in the collection chamber 311 can be cleaned. Pour out the lint, and the filter element 330 and the lifting rib body 310 can be rinsed with water. When necessary, the filter element 330 can also be disassembled or replaced. Finally, reinstall it in the reverse order.

[0092] The lifting rib 300 provided in this embodiment can be made of hard plastic. The lifting rib 300 has a lint filtering function, and the lifting rib 300 is easy to install and disassemble, facilitating the cleaning of lint. When in use, the water inlet 312 only allows water to enter and does not allow water to flow out, enabling only lint to enter and not flow out again after entering. At the same time, an appropriate amount of water is stored inside the lifting rib 300. When the lifting rib 300 rotates to near the top of the inner cylinder 200, the water inside the lifting rib 300 is discharged from the water outlet 313, and the water flow hammers the clothes from top to bottom, improving the washing effect. When dehydrating, the water permeable component 340 is opened, and the water accumulated inside the lint in the lifting rib 300 is discharged under the action of centrifugal force, avoiding excessive water accumulation in the lint resulting in uneven weight and preventing abnormal vibration of the washing machine.

[0093] Embodiment Two

[0094] Figures 12 to 16 Embodiment Two is shown, in which the same or corresponding components as those in Embodiment One are provided with the corresponding reference numerals in Embodiment One. For simplicity, only the differences between Embodiment Two and Embodiment One are described. The difference lies in that the one-way conduction member 320 includes a valve plate 323 and a hinge structure 324. The valve plate 323 is installed on the inner wall of the collection chamber 311 through the hinge structure 324. After the valve plate 323 droops, it exactly covers the water inlet hole, and the valve plate 323 can be opened unidirectionally, so that the effect of restricting water outflow on one side while allowing water to enter on the other side can be achieved.

[0095] The hinge structure 324 includes a hinge shaft and a torsion spring. The torsion spring is sleeved on the hinge shaft, and one end of the valve plate 323 is rotatably connected to the hinge shaft. Multiple hinge shafts can be provided, and the valve plate 323 corresponds to the hinge shaft one by one. Multiple valve plates 323 can also share one hinge shaft, which is convenient for installation and reduces the number of components. The hinge shaft extends along the front-back direction of the lifting rib body 310.
