[0002] In order to improve the problem that the lifting ribs of the drum washing machine filter lint, which affects the flow of washing water from the outlet.

[0003] In the prior art, a lint filter is usually arranged in a lifting rib in a drum washing machine. For example, the invention patent with application number CN108866941 A discloses a lifting rib of a drum washing machine, which is provided with the lifting rib on the side wall of the inner barrel of the drum washing machine, including a shell, wherein a accommodating cavity with a cavity structure is formed in the shell, the shell includes a peripheral wall connected to the side wall of the inner barrel and a top wall connected to the peripheral wall and spaced a certain distance from the side wall of the inner barrel, a drainage hole is provided on the top wall, the drainage hole connects the accommodating cavity with the inner barrel, the opening of the drainage hole at one end of the inner wall of the shell is smaller than the opening at one end of the outer wall of the shell, when there are too many lints in the drum washing machine, the drainage hole is easily blocked by the lints, thereby blocking the washing water from flowing out of the water outlet, affecting the user's experience.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The object of the present invention is to provide a lifting rib of a drum washing machine, wherein a cavity is formed inside the lifting rib, and a water outlet and a water inlet are respectively arranged on the top wall and the side wall of the cavity, a filter is arranged between the water inlet and the water outlet, and the filter at least partially protrudes in the direction away from the top wall. When water flows through the filter, lint is blocked by the filter and is guided by the protruding part and accumulated around the protruding part, thereby preventing the lint from covering the filter and preventing the water from passing smoothly, and at the same time enabling the lifting rib to have the function of filtering lint.

[0006] Another object of the present invention is to provide a drum washing machine, in which the above-mentioned lifting ribs are installed on the inner wall of the inner drum, and the part of the inner drum covered by the lifting ribs is provided with a water hole connecting the two sides of the inner drum, and the water hole can only realize the unidirectional flow of water from the inside of the cavity to the outside, and then during the dehydration rotation, the residual water in the cavity can be discharged, and at the same time, the lint will not be discharged synchronously with the residual water, thereby realizing the collection of lint.

[0007] To achieve the above object, the technical solution of the present invention is:

[0008] A lifting rib of a drum washing machine, wherein a cavity is formed in the lifting rib, comprising a top wall and a side wall, a water outlet is arranged on the top wall, a water inlet is arranged on the side wall, a filter is arranged in the cavity, and the water inlet and the water outlet are separated on both sides of the filter by the filter;

[0009] The filter net is at least partially protruding away from the top wall. The filter net is partially protruding away from the top wall. While filtering the wire scraps, the wire scraps can be guided to accumulate around the protruding portion, preventing the wire scraps from completely covering the filter net and preventing water from passing through. The filtered wire scraps remain in the cavity, thereby achieving the filtering and collection of the wire scraps.

[0010] Optionally, the filter net includes at least a first part and a second part, one end of the first part and the second part are respectively connected to the inner wall of the cavity, and the other end extends from the connection point in a direction away from the water outlet and is connected to form a protrusion, separating the water inlet and the water outlet on both sides of the filter net.

[0011] The above scheme increases the area of ​​the filter screen, and the lint blocked by the filter screen is gathered near the inner wall of the cavity under the guidance of the inclined surfaces of the first and second parts, further reducing the probability of the filter screen being completely covered by the lint, and can better ensure the passage of water.

[0012] Optionally, the lifting ribs include a top wall and a side wall, and the water outlet and the water inlet are arranged on the top wall and the side wall respectively;

[0013] One end of the first part and the second part of the filter is fixed at the junction of the top wall and the side wall, and the protrusion formed at the other end is opposite to the position of the water outlet, which can better avoid the position of the water outlet and reduce the influence of the attachment of lint on the water flow velocity in the cavity. The water flow discharged from the water outlet can form a water curtain with a higher flow rate, thereby improving the cleaning ability of the drum washing machine.

[0014] Optionally, the first part and the second part are flat-plate shaped as a whole, and the first part and the second part are integrally arranged to form the filter screen;

[0015] The filter screen is made of elastic material and has an initial state. In the initial state, the distance between one end of the first part and one end of the second part connected to the inner wall is greater than the width of the top wall.

[0016] In the above scheme, the filter can only be installed in the cavity after being compressed and deformed, thereby realizing the detachable setting of the filter, which is convenient for users to clean and maintain; the force applied to the inner wall of the cavity by restoring the filter to its initial state can further improve the reliability of the filter installation.

[0017] Optionally, multiple layers of filter screens are arranged in the cavity, and the closer the filter screen is to the water outlet, the smaller the filter hole is, and the multiple layers of filter screens are fixed at the junction of the top wall and the side wall. The multi-stage filter screens can more effectively block the lint; the filter screens are used to grade the lint of different sizes, which avoids the entanglement of lint of different lengths with each other, and further reduces the probability of the filter screen being blocked by lint.

[0018] Preferably, the filter screen includes a first filter screen and a second filter screen arranged from the water inlet to the water outlet, and the filter holes of the first filter screen are larger than the filter holes of the second filter screen. When the drum washing machine is in the washing state, the washing water enters the cavity from the water inlet and first passes through the first filter screen to filter the larger lint, and then passes through the second filter screen to filter the smaller lint.

[0019] Optionally, a water inlet is provided on at least two opposite side walls of the lifting rib, and the edge of the water inlet extends into the cavity to form a water inlet channel; the water inlet extends into the cavity to form a water inlet channel, the water inlet and the water inlet channel are not on the same axis, and the water inlet channel is inclined away from the water outlet.

[0020] In the above scheme, the water inlet is arranged on at least two side walls opposite to the lifting ribs, so that water can enter the cavity from multiple directions, cooperating with the washing process of the inner drum alternating forward and reverse rotation, and always maintaining the generation of the water curtain during the washing process; by setting the water inlet channel, it is avoided that water enters the cavity from the water inlet on one side and is directly discharged from the water inlet on the other side, so that the cavity can better store water, which is more conducive to the formation of the water curtain.

[0021] Preferably, a flexible rubber sleeve is provided at the end of the water inlet channel.

[0022] In the above scheme, the flexible rubber sleeve plays a role similar to a switch, which can be opened when water flows through, and closed when the water flows in the reverse direction to close the water inlet channel, thereby further improving the water storage effect of the cavity.

[0023] Optionally, a plurality of water inlets are spaced apart on the side wall in a direction parallel to the top wall, and the water inlets on the two side walls are staggered, which reduces the probability of water entering from the water inlet on one side and then being directly discharged from the water inlet on the other side, thereby improving the water storage capacity of the cavity.

[0024] Preferably, the width of the water inlet in the direction parallel to the top wall is greater than the width in other directions, the shape of the water inlet channel is adapted to the shape of the water inlet, and when the rubber sleeve is in place and no washing water enters the rubber sleeve, the rubber sleeve is more easily closed, further preventing the washing water entering the cavity from flowing out of the water inlet. Optionally, the water outlet is elliptical in shape as a whole, and is gradually opened inward from the outside of the lifting rib. The shape and contraction of the water outlet further increase the flow rate of the water flow at the water outlet; even when there is less water in the cavity, the structure can be used to discharge water at a faster speed, and a water curtain can be formed more stably.

[0025] Optionally, the lifting rib further comprises a bottom wall, and the bottom wall, top wall and side walls cooperate to form the cavity; a semi-permeable hole is provided on the bottom wall for one-way communication of water from the inside of the cavity to the outside.

[0026] In the above scheme, the semi-permeable holes can only realize one-way flow of water, preventing the wire scraps from being discharged along with the water, and then retaining the wire scraps in the cavity of the lifting ribs, so that the lifting ribs have the function of storing wire scraps, which is convenient for users to clean the wire scraps uniformly.

[0027] Preferably, the semi-permeable holes are formed by cross-cuts and longitudinal cuts cross-arranged on the soft material. When the drum washing machine performs the spin-drying step, the lint collected in the lifting ribs is subjected to the centrifugal force to discharge the residual water in the cavity, while blocking the lint to prevent the washing machine from becoming eccentric due to the weight difference of the lifting ribs during the dehydration process.

[0028] The present invention also provides a drum washing machine using the lifting ribs.

[0029] In the above scheme, the lifting ribs are arranged on the peripheral wall of the inner drum. During the washing process, no matter the inner drum rotates forward or reversely, the water flow can enter the cavity through the water inlet to form a water curtain; the lint that enters the cavity with the water is blocked by the filter net and remains in the cavity, thereby achieving the filtering of the lint.

[0030] Optionally, the lifting ribs are detachably fixed on the circumferential wall of the inner drum, and the portion of the circumferential wall of the inner drum covered by the lifting ribs is provided with a water passing area connecting the two sides of the circumferential wall of the inner drum, and the semi-permeable holes are connected to the outside of the inner drum through the water passing area. When the washing machine is in the spin-drying step, the lint filtered in the lifting ribs is subjected to the centrifugal force to throw the water out of the semi-permeable holes, while the lint is blocked by the semi-permeable holes and will not be thrown out of the lifting ribs, that is, the lint entering the cavity will not be discharged during the washing or dehydration process, thereby realizing the collection of lint, which is convenient for users to clean.

[0031] Optionally, the bottom wall of the lifting rib has a protruding rib on one side facing the outside of the cavity, and when the lifting rib is installed in place, the end of the rib abuts against the peripheral wall of the inner tube, forming a gap between the lifting rib and the peripheral wall of the inner tube.

[0032] The present invention has at least the following beneficial effects:

[0033] 1. The present invention arranges a multi-layer filter between the water inlet and the water outlet of the lifting rib, and the filter holes of the filter gradually decrease from the water inlet to the water outlet. In the process of washing water entering the cavity from the water inlet to flowing out of the cavity at the water outlet, the lint in the washing water is filtered at multiple stages by the multi-layer filter and filtered onto the filter, thereby achieving filtrating of lint while forming a water curtain.

[0034] 2. The present invention forms a water inlet channel by extending the water inlet toward the cavity near the cavity, and the water inlet channel and the water inlet are arranged in different directions at the lifting ribs, thereby preventing the washing water entering the cavity from the water inlet on one side from flowing out from the water inlet on the other side wall. In addition, the water inlet channel is also equipped with a rubber sleeve, and the washing water enters the cavity through the rubber sleeve. After the water intake is completed, the rubber sleeve naturally droops to block the water inlet, further preventing the washing water entering the cavity from flowing out from the water inlet again, thereby improving the water storage capacity of the lifting ribs, being conducive to forming a stable water curtain, and improving the cleaning effect of the drum washing machine.

[0035] 3. The present invention arranges semi-permeable holes on the bottom wall of the lifting ribs. When the drum washing machine is in the spin-drying step, the residual water in the cavity of the lifting ribs is thrown out from the semi-permeable holes due to the centrifugal force, while the lint is blocked by the semi-permeable holes and stays in the cavity, thereby realizing the collection of lint and facilitating cleaning by users; at the same time, it also avoids the residual water in the lifting ribs causing changes in the weight distribution of the inner drum and thus causing eccentricity, which will not affect the dehydration.

DETAILED DESCRIPTION

[0044] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0045] In the description of the present invention, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0046] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0047] The present invention discloses a lifting rib 300 of a drum washing machine 100. A cavity is formed in the lifting rib 300. The cavity is connected to the outside through a water inlet 350 and a water outlet 340. The lifting rib 300 also includes a filter 500. The filter 500 is arranged in the cavity to separate the water inlet 350 and the water outlet 340 on both sides of the filter. The filter 500 is at least partially protruded in a direction away from the water outlet 340. During the washing process, the lifting rib 300 rotates synchronously with the inner drum 600. When the lifting rib 300 rotates to the bottom position of the inner drum 600, the washing water is discharged from the inlet of the lifting rib 300. The water enters through the water inlet 350 and is accumulated in the cavity inside the lifting rib 300. When the lifting rib 300 rotates to a position near the top along with the inner drum 600, the washing water flows out from the water outlet 340. During this process, the lint is blocked by the filter 500 and remains on the filter 500. It is guided by the protruding portion of the filter 500 and gathers around the protruding portion, and does not completely cover the surface of the filter 500 to block the filter 500. This ensures that the lifting ribs can smoothly form a water curtain while giving the lifting ribs 300 the function of filtering lint, thereby improving the user experience.

[0048] Furthermore, the filter net 500 includes at least a first part and a second part, one end of the first part and the second part are respectively connected to the inner wall of the cavity, and the other end extends from the connection in a direction away from the water outlet 340 and is connected to form a protrusion, separating the water inlet 350 and the water outlet 340 on both sides of the filter net 500. It should be noted that the first part can be a straight plate shape or an arc shape, and can be adjusted according to the specific structure inside the lifting rib cavity.

[0049] Furthermore, one end of the first part and the second part of the filter 500 is fixed at the junction of the top wall and the side wall, and the protrusion formed at the other end is arranged opposite to the water outlet 340. Specifically, the projection of the filter 500 on the longitudinal section of the lifting rib 300 is V-shaped, U-shaped or arc-shaped, and the water outlet 340 is arranged opposite to the gradually shrinking end of the V-shaped, U-shaped or arc-shaped filter. The lint blocked by the filter 500 is guided by the filter 500 and pushed by the water flow to gather near the connection between the V-shaped, U-shaped or arc-shaped filter 500 and the inner wall of the cavity, thereby avoiding the influence of the attachment of lint on the flow rate of water passing through the filter. On the other hand, when the washing water flows out through the water outlet 340, the lifting rib 300 is just located at the top position of the inner drum 600. At this time, the water flow of the water outlet 340 forms a water curtain, which hammers the clothes. While completing the filtration of the washing water, the lifting rib 300 further improves the clothes washing ability of the drum washing machine 100 through the water curtain.

[0050] Furthermore, multiple filter screens 500 are arranged between the water inlet 350 and the water outlet 340, and the closer the filter screen is to the water outlet 340, the smaller the filter hole is. The lifting ribs 300 are used to arrange filter screens 500 with gradually smaller filter holes between the water inlet 350 and the water outlet 340 to filter the lint in a graded manner. While improving the effect of the lifting ribs 300 in filtering the lint, the lint can be more easily gathered under the guidance of the filter screen 500, preventing lint of different sizes from being attached to the surface of the filter screen 500 in a tangled manner, causing the filter screen to be covered with lint.

[0051] As a specific implementation of this embodiment, Figure 2 , Figure 3 As shown, the cross-section and longitudinal section of the lifting rib 300 are both roughly trapezoidal, and the filter screen 500 is installed in the cavity inside the lifting rib 300 in a V-shape on the axial longitudinal section of the inner drum 600, and the water outlet 340 is opposite to the V-shaped tip of the filter screen 500. When the lifting rib 300 rotates with the inner drum 600 to the upper end of the drum washing machine 100, the lint after the washing water is filtered by the filter screen 500 gathers to both sides along the slope of the V-shaped filter screen 500, avoiding the position of the water outlet 340, preventing the lint from being lost from the water outlet 340 without affecting the drainage efficiency.

[0052] As a specific implementation of this embodiment, when two rows of water outlets 340 are set on the top wall in the radial direction of the drum washing machine 100, the filter 500 is installed in the cavity inside the lifting rib 300 in a W-shape on the axial longitudinal section of the inner drum 600, and the two rows of water outlets 340 are respectively opposite to the two W-shaped protrusions of the filter 500, ensuring that the filtered linen scraps avoid the position of the water outlet 340 and do not affect the drainage efficiency.

[0053] Furthermore, the bottom wall 400 is installed at the bottom of the cavity in cooperation with the side wall, the width of the bottom wall 400 of the lifting rib 300 is greater than the width of the top wall, and the side wall is inclined between the top wall and the bottom wall 400. When the drum washing machine 100 is in a washing state, the inclined side wall is conducive to the washing water entering the cavity of the lifting rib 300 from the water inlet 350, and when the lifting rib 300 rotates to the upper end position of the drum washing machine 100 with the inner drum 600, the inclined side wall produces a gathering effect on the washing water, thereby increasing the water pressure at the water outlet 340 and increasing the speed of the washing water discharged from the water outlet 340, thereby enhancing the hammering effect of the water curtain on the clothes, and further improving the washing ability of the drum washing machine 100 on the clothes.

[0054] Furthermore, the opening of the water outlet 340 on one side close to the cavity is larger than the opening on the other side. When the lifting rib 300 rotates to the upper end along with the inner drum 600, the washing water flows out from the water outlet 340 to form a water curtain to hammer the clothes at the lower end. The larger outlet close to the cavity is conducive to the washing water flowing out of the cavity. When the washing water in the cavity becomes less, the water outlet 340 will also gather the washing water in the cavity into a water curtain and spray it out instead of scattering it in drops. In addition, if Figure 1 As shown, the opening of the water outlet 340 on the top wall of the lifting rib 300 is elliptical, which further improves the water gathering capacity of the water outlet 340 and improves the water curtain effect formed by the washing water from the water outlet 340, thereby further enhancing the cleaning effect of the drum washing machine 100.

[0055] Furthermore, a plurality of water inlets 350 and water outlets 340 are respectively arranged along the side walls and top walls of the lifting ribs 300. The lifting ribs 300 filter the washing water as the inner drum 600 rotates. The multiple water inlets 350 arranged on the two side walls ensure that washing water can enter the cavity regardless of whether the inner drum 600 rotates forward or reversely during the washing process, thereby ensuring stable generation of the water curtain. The multiple water outlets 340 ensure the coverage of the water curtain, which can more fully hammer the laundry, further improving the washing effect of the drum washing machine 100.

[0056] Further, as a specific implementation of this embodiment, Figure 3 As shown, the filter 500 includes a first filter and a second filter arranged from the water inlet 350 to the water outlet 340. The first filter is integrally mounted on the second filter. The filter holes of the first filter are larger than the filter holes of the second filter. In the process of the washing water flowing from the water inlet 350 through the water outlet 340, the first filter and the second filter perform multi-stage filtration on the washing water. The larger lint in the washing water is blocked by the first filter, and the smaller lint is blocked by the second filter. By graded filtration of the lint, entanglement between lints of different sizes is avoided, so that the lint can be better gathered under the guidance of the filter, thereby reducing the probability of clogging of the filter 500.

[0057] Furthermore, as a preferred implementation mode of this embodiment, in order to facilitate the installation and disassembly of the first filter screen and the second filter screen in the cavity, the first filter screen and the second filter screen are both installed at the junction of the top wall and the side wall of the cavity, and the filter screen 500 is made of elastic material and has an initial state. In the initial state, the distance between the end of the first part and the end of the second part is greater than the width of the top wall, so that the filter screen 500 is in a compressed state when installed in place, and the filter screen 500 can continuously apply force to the junction of the top wall and the side wall. An installation groove for installing the filter screen 500 is set at the connection between the top wall and the side wall of the cavity. After the filter screen 500 abuts against the installation groove, it can be stably installed in the cavity by relying on the force applied by the filter screen 500, and this installation method is easy to disassemble, thereby improving the user experience.

[0058] During operation of the drum washing machine 100 , in order to further prevent the washing water entering the cavity through the water inlet 350 on one side of the lifting rib 300 from flowing out through the water inlet 350 on the other side, the water inlets 350 on the two side walls are staggered. Furthermore, as a specific implementation of this embodiment, the water inlet 350 extends toward the inner cavity on one side close to the cavity to form a water inlet channel 360. The water inlet 350 is connected to the cavity through the water inlet channel 360, and the water inlet 350 and the water inlet channel are set at different angles. In this implementation, the water inlet channel is tilted downward as a whole. When washing water enters the water inlet channel through the water inlet 350, it is guided by the downward tilted water inlet channel to prevent the washing water from flowing out from the water inlet 350 on the other side, thereby further improving the water storage and filtering performance of the lifting rib 300. On the other hand, it ensures that there is enough washing water in the cavity of the lifting rib 300. After the washing water is filtered by the filter net 500, the washing water flowing out from the water outlet 340 forms a water curtain to rinse the clothes, thereby improving the clothes washing ability of the drum washing machine 100.

[0059] Furthermore, a rubber sleeve 370 is installed at the water outlet end of the water inlet channel 360. The rubber sleeve 370 is flexible, that is, it can be affected by gravity and sag in the direction of gravity in a static state. After the washing water enters through the water inlet 350 through the water inlet channel 360, it enters the cavity of the lifting rib 300 through the rubber sleeve 370. Specifically, a circle of grooves is arranged around the outer wall of the water outlet end of the water inlet channel 360. The rubber sleeve 370 is fixed in the groove of the outer wall of the water inlet channel 360. When the washing water passes through the rubber sleeve 370, When the rubber sleeve 370 enters the cavity, the rubber sleeve 370 is squeezed and stretched by the water flow. After the washing water has finished flowing in, the rubber sleeve 370 naturally deflates and droops, blocking the washing water in the cavity from flowing out from the water inlet 350. That is, the rubber sleeve 370 plays a function similar to a switch, which prevents water from being discharged from the water inlet 350 while realizing one-way water inlet at the water inlet 350, thereby improving the water storage capacity of the lifting ribs, thereby improving the stability of the water curtain and the beating force of the water curtain on the laundry, thereby improving the user experience.

[0060] Furthermore, as a specific implementation of this embodiment, after the lifting rib 300 is installed in place in the inner cylinder 600, the length of the opening of the water inlet 350 in the axial direction of the inner cylinder 600 is greater than the length of the opening in the radial direction, and the water inlet channel of the mounting platform 360 is adapted to the shape of the water inlet hole. When the washing water passes through the water inlet channel from the water inlet 350 and finally enters the cavity through the rubber sleeve 370, since the rubber sleeve 370 is installed on the flat mounting platform 360 and no washing water passes through the rubber sleeve 370, the rubber sleeve 370 naturally becomes deflated and is easier to seal, thereby preventing the washing water that has entered the cavity from flowing out of the cavity through the water inlet 350 on the other side.

[0061] Furthermore, in the drum washing machine 100 described in this embodiment, the bottom wall 400 blocks the bottom of the cavity and is installed on the peripheral wall of the inner drum 600 through the staples 330. Generally speaking, the inner drum 600 does not have a water flow area at the position where the lifting ribs 300 are installed. In the present invention, the part of the inner drum 600 covered by the lifting ribs is provided with a water flow area that connects the two sides of the inner drum 600, and a semi-transparent hole 420 is provided on the bottom wall 400. When the lifting ribs are installed in place, the semi-transparent hole 420 is located in the water flow area.

[0062] Furthermore, as an implementation method of this embodiment, a water hole 610 is set in the water flow area, and the water hole 610 is arranged opposite to the semi-permeable hole 420. When the drum washing machine 100 performs the spin-drying step, the residual moisture of the lint in the lifting rib 300 is thrown out through the semi-permeable hole 420 and the water hole 610 under the action of centrifugal force.

[0063] As an implementation method of this embodiment, Figure 2 , Figure 4 , Figure 5 As shown, a semi-permeable hole 420 is provided on the bottom wall 400, and the bottom wall 400 is made of soft materials such as silicone and rubber. An incision is cut on the bottom wall 400. Specifically, the semi-permeable hole 420 is formed by the transverse incisions 422 and the longitudinal incisions 423 staggered on the soft material. After the incisions are formed on the soft material, the soft materials on both sides of the incisions will still squeeze each other. When the drum washing machine 100 is in the washing state, the rotation speed is low, and the centrifugal force is insufficient to throw out the washing water entering the lifting rib 300; when the drum washing machine 100 is in the dehydration state, the rotation speed increases, the centrifugal force on the incision increases, and it is partially opened to dehydrate the thread scraps in the lifting rib 300, and the thread scraps in the cavity are blocked by the semi-permeable hole 420 and will not be thrown out of the cavity of the lifting rib 300. Dehydrating the thread scraps in the lifting rib 300 assembly can prevent the thread scraps from breeding bacteria, reduce weight, thereby reducing the vibration of the washing machine, and improve the user experience.

[0064] Furthermore, in order to make the wall petal 424 of the semi-permeable hole 420 at the incision thinner, a pit 421 is formed on the bottom wall 400. When the drum washing machine 100 is in the spin-drying state, the incision is more likely to be partially opened due to the action of centrifugal force, thereby improving the dehydration efficiency of the lint, and the lint after dehydration is easier to clean.

[0065] Furthermore, in order to improve the matching degree between the semi-permeable hole 420 on the bottom wall 400 and the water hole 610 on the inner cylinder 600, ensure that the positions of the semi-permeable hole 420 and the water hole 610 are relative, and improve the dehydration efficiency of the wire scraps in the lifting rib 300, a convex rib 410 is set at the contact position between the bottom wall 400 and the inner cylinder 600, and the convex rib 410 and the semi-permeable hole 420 are arranged at intervals, and the spacing between the convex rib 410 and the semi-permeable hole 420 is equal to the spacing between the convex rib 410 and the water hole 610. When the lifting rib 300 is installed in place on the inner cylinder 600, the semi-permeable holes 420 are all opposite to the water hole 610.

[0066] Furthermore, the lifting rib 300 is detachably arranged on the inner cylinder 600. When the lifting rib 300 needs to be cleaned, the lifting rib 300 is removed from the inner cylinder 600, and after the bottom wall 400 is removed, the wire scraps between the bottom wall 400 and the first filter screen, and between the first filter screen and the second filter screen are removed.

[0067] Further, such as Figure 2 As shown, the lifting rib 300 is provided with reinforcement parts 310 along the axial sides of the inner cylinder 600 in the installation direction of the inner cylinder 600, and a receiving space is formed inside the reinforcement part 310. A staple 330 and a first spring 320 are installed on the side of the receiving space away from the cavity. The first spring 320 is arranged along the axial direction of the inner cylinder 600. When the lifting rib 300 is installed in place on the inner cylinder 600, the first spring 320 is in a compressed state, respectively abutting against the inner cylinder 600 and the reinforcement part 310. The lifting rib 300 is fixed to the inner cylinder 600 by cooperating with a plurality of staples 330 and a plurality of first springs 320 respectively provided on the two reinforcement parts 310. Exemplarily, there are 4 staples 330 and 4 first springs 320.

[0068] Further, such as Figure 6 , Figure 7 As shown, the staple 330 includes a guide cap 331, a screw 332, and a second spring 333; the screw 332 is fixed to the bottom of the side wall of the reinforcement portion 310 of the lifting rib 300 by threads, the guide cap 331 is a hemispherical shell or a hemispherical shell-like shape, the second spring 333 is installed inside the guide cap 331, and the other side abuts against the nut of the screw 332, and the center of the guide cap 331 has a center hole for the screw 332 to pass through, when the lifting rib 300 is installed on the inner cylinder 600 by the staple 330, the guide cap 331 and the outer wall of the inner cylinder 600 are kept pressed tightly, and the second spring 333 provides elastic force to the guide cap 331 to ensure that the lifting rib 300 and the inner cylinder 600 are firmly installed.

[0069] Furthermore, as a specific implementation of this embodiment, in order to ensure the stability of the lifting rib 300 installed in the inner cylinder 600, the two corners of the reinforcement part 310 on both sides of the lifting rib 300 are provided with pins 330 and the first spring 320, and the lifting rib 300 is fixed to the inner cylinder 600 by four pins 330 and the first spring 320.

[0070] Specifically, Figure 7 As shown, the inner cylinder 600 is provided with a slot 630 at a corresponding position, and the slot 630 includes a circular hole 631, a first vertical slot 632, a transverse slot 633, a flange 620 perpendicular to the inner wall of the inner cylinder 600 formed by folding the transverse slot 633 when cutting, and a second vertical slot 634, wherein the length of the first vertical slot 632 is longer than the length of the second vertical slot 634. When the lifting rib 300 is installed on the inner cylinder 600, the user places the lifting rib 300 at the corresponding position of the inner cylinder 600, and aligns one of the staples 330 with the circular hole 631 of the slot 630 and inserts it, and then rotates the lifting rib 300 to ensure that all the staples 330 are in place and inserted into the circular hole 631. At this time, the first spring 320 abuts against the flange 620, as shown in FIG. Figure 7 As shown, the lifting rib 300 is pulled down along the first vertical groove 632 as a whole to compress the first spring 320 so that the staple 330 reaches the position of the transverse groove 633, and then the lifting rib 300 is moved horizontally, and the staple 330 moves along the transverse groove 633 to the second vertical groove 634. After releasing the hand at this moment, the first spring 320 will push the lifting rib 300 to move upward, and the staple 330 is pressed against the top of the second vertical groove 634. Since the length of the first spring 320 is longer than the length of the second vertical groove 634 and smaller than the length of the first vertical groove 632, when the staple 330 is located in the second vertical groove 634, the first spring 320 is in a compressed state, fixing the staple 330 in the second vertical groove 634, so that the lifting rib 300 is fixed in all directions, thereby realizing the installation of the lifting rib 300. In the absence of external human force, the lifting rib 300 will not loosen during washing.

[0071] Furthermore, after the lifting rib 300 is installed in place in the inner cylinder 600 , the first spring 320 and the second spring 333 respectively exert forces on the staple 330 along the axial and radial directions of the inner cylinder 600 , ensuring that the lifting rib 300 is firmly installed on the inner cylinder 600 .

[0072] Furthermore, when the lifting rib 300 needs to be disassembled, the reinforcement portion 310 of the lifting rib 300 is compressed to the bottom along the second vertical groove 634 against the first spring 320, and then moves along the transverse groove 633 to the first vertical groove 632. Since the length of the first vertical groove 632 is greater than the length of the first spring 320, the first spring 320 naturally stretches, and the elastic force on the lifting rib 300 disappears. When the pin 330 moves to the top of the second vertical groove 634, the lifting rib 300 can be taken out of the circular hole 631, thereby realizing the disassembly of the lifting rib 300 in the inner cylinder 600.
