Description

TECHNICAL FIELD

[0001] The present application relates to the field of washing machines, in particular, to a laundry treatment apparatus. BACKGROUND

[0002] The lifting ribs are often arranged in the inner drum of the washing machine to lift the water flow. The existing patents use the lifting ribs to set the filter structure, so that the water flow in the washing drum can be filtered by the lifting ribs. The filter structure arranged in the lifting rib is usually a filter screen. The lint and other residues are easy to remain on the filter screen, and it is difficult to clean the filter screen. Usually, the filter screen needs to be replaced regularly. The mesh of the filter screen is usually arranged relatively small. Once the lint and other residues are accumulated on the filter screen, the filter screen is easy to be blocked. Moreover, the filter screen is a planar structure, so that the contact area between the filter screen and the lint and other impurities is small, thereby affecting the filtering effect. In view of the above-mentioned shortcomings of the filter screen structure arranged in the lifting rib, the present application needs a filter structure arranged in the lifting rib, which can better filter the lint and other impurities, and is not easy to be blocked by the lint and other impurities and easy to clean.

[0003] In view of the above problems, the present application is proposed. SUMMARY

[0004] The present application aims to provide a lifting rib. The filter structure arranged in the lifting rib can not only better filter the lint and other impurities, but also is not easy to be blocked by the lint and other impurities, and is easy to clean. The present application also aims to provide a laundry treatment apparatus. The water in the washing drum can be filtered by the lifting rib, and the lifting rib is not easy to be blocked in the filtering process.

[0005] The present application provides a lifting rib, which comprises an outer shell, a through hole for water flow in and out is arranged on the outer shell, a hollow inner cavity is formed in the outer shell, and a comb-shaped filter structure is arranged in the inner cavity. The water flow in the washing drum is filtered by the comb-shaped filter structure. Compared with the filter screen, the comb-shaped filter structure is not easy to be blocked by the lint and other residues. Moreover, the filter screen is a planar structure, and the comb-shaped filter structure is a three-dimensional extension structure. The contact area between the comb-shaped filter structure and the water flow is larger, so that the comb-shaped filter structure can achieve better filtering effect.

[0006] Further, the specific structure of the comb-shaped filter structure is that the comb-shaped filter structure comprises a plurality of combs, and the comb is a cylindrical structure.

[0007] Further, the through hole is arranged on any side wall of the outer shell, the comb is fixed on the side wall where the through hole is arranged, the top of the comb is connected with the side wall, and the comb extends towards the inner wall of the washing drum. The comb is arranged close to the through hole, so that the comb is close to the water source of the through hole.

[0008] Further, the water flow direction of the at least one through hole intersects with the extending direction of any comb tooth. That is, the extending direction of the comb tooth is such that the comb tooth can be contacted by the water flow flowing from the through hole, thereby achieving the effect of facilitating filtration of the comb tooth.

[0009] Further, the arrangement of the plurality of comb teeth is that a plurality of comb teeth are arranged on the same side wall, and the plurality of comb teeth are uniformly distributed on the side wall; when the plurality of comb teeth are arranged in rows, the plurality of comb teeth in each row are transversely equidistantly arranged; and / or when the plurality of comb teeth are arranged in columns, the plurality of comb teeth in each column are longitudinally equidistantly arranged.

[0010] Further, the plurality of comb teeth are arranged in multiple rows on the side wall, and the comb teeth between adjacent two rows are staggered; the extending length of the comb teeth in each row is the same, and the extending length of the comb teeth in adjacent two rows is different. The staggered arrangement of the comb teeth between adjacent two rows avoids mutual blocking between the comb teeth in adjacent two rows, thereby enabling the water flow to contact more comb teeth when flowing in any direction in the lifting rib, and enabling the water flow to be filtered by the plurality of comb teeth. Similarly, the extending length of the comb teeth in adjacent rows is different, which avoids blocking at the bottom of the adjacent comb teeth, and also enables the water flow to contact more comb teeth.

[0011] As an embodiment, the comb tooth-shaped filtering structure further comprises a "tree" structure that spreads outward, and the "tree" structure comprises a cylindrical rod that is a "trunk", and the cylindrical rod is provided with outwardly protruding "branch" shaped filtering rods.

[0012] Further, the filtering rods are obliquely arranged on the cylindrical rod, and the filtering rods gradually extend outward from the bottom to the top along the axial direction of the cylindrical rod; a plurality of filtering rods are arranged on different sides of the cylindrical rod, and the plurality of filtering rods on each side are sequentially arranged along the axial direction of the cylindrical rod. The obliquely arranged filtering rods make it easier for lint and other impurities to be intercepted by the filtering rods, and the plurality of filtering rods arranged on the cylindrical rod enable the plurality of filtering rods to intercept lint and other impurities, thereby achieving a better filtering effect.

[0013] Further, the filtering rod of the comb tooth extends to the side of the cylindrical rod where the through hole is closest to, and the filtering rod projects to the side wall where the through hole is arranged, and the projection can cover part of the area of the through hole; all the filtering rods arranged on any comb tooth have gaps between the comb tooth and the adjacent comb teeth around it. The filtering rod of the comb tooth extends to the side of the cylindrical rod where the through hole is closest to, so that the water flow flowing out of the through hole can contact the filtering rod, thereby facilitating the filtering rod to intercept lint and other impurities in the water flow. While the filtering rod on the comb tooth extends to the surrounding through hole, it also needs to not contact the surrounding adjacent comb teeth. Because if the filtering rod on the comb tooth has a position of abutting contact with the surrounding adjacent comb teeth, it may easily cause blockage of the water flow.

[0014] The application further provides a clothes treatment device, wherein the lifting rib is arranged as described above.

[0015] Compared with the prior art, the application has the following beneficial effects:

[0016] 1) The lifting rib of the application filters the water flow in the washing cylinder through the comb-shaped filter structure. Compared with the prior art of arranging a filter screen in the lifting rib to filter the water flow in the washing cylinder, the thickness of the filter screen is small, while the comb-shaped filter structure is a three-dimensional extension structure, so that the comb-shaped filter structure can achieve better filtering effect. Moreover, the mesh gap of the filter screen is small and not easy to clean, while the comb-shaped filter structure is relatively not easy to be blocked by lint and other residues, which affects the filtering effect, and is more convenient to clean.

[0017] 2) The application provides two forms of combs, one is arranged in a cylindrical structure, which is relatively convenient to process. The other comb is arranged with a filter rod extending outward in the form of a "branch" on the cylindrical rod, so that the comb has a structure similar to a "tree", thereby increasing the contact area of the comb with the water flow, so that the comb has better filtering effect. In actual use, the user can select the appropriate comb form according to actual needs.

[0018] 3) The filter rod structure arranged on the cylindrical rod is also reasonable. The filter rod is arranged obliquely on the cylindrical rod, so that compared with the filter rod arranged vertically on the cylindrical rod, the oblique filter rod is more likely to cause the lint and other impurities to be clamped or suspended on the filter rod, so that the filter rod achieves better filtering effect. Moreover, multiple filter rods are arranged on each side of the cylindrical rod, so that the multiple filter rods have better effect of intercepting lint and other impurities. The filter rods on each side are arranged in sequence along the axial direction, so that the comb occupies a smaller volume, avoiding mutual influence between adjacent combs.

[0019] 4) The comb of the application is arranged on the inner surface of the side wall with through holes. Since the water flow flows into the through holes on the side wall, the amount of water flow on the inner surface of the side wall is large and concentrated, so that the comb can contact more water flow, thereby filtering more water flow. Moreover, the comb extends from the inner surface to the inner wall of the washing cylinder, so that the arrangement direction of the comb is consistent with the flow direction of the water flow flowing into the lifting rib, thereby making the comb contact more water flow to filter more water flow.

[0020] 5) The position of the filter rods on the comb teeth in the present application is reasonable, the filter rods all extend to the closest through hole on the setting side, so that the water flow flowing into the through hole can contact the filter rods, and then the lint and other impurities in the water flow are more easily intercepted by the filter rods, thereby ensuring the filtering effect. During the extension of the filter rods to the through hole, attention should also be paid to not contacting the surrounding adjacent comb teeth. When the filter rods have an abutting portion with the surrounding adjacent comb teeth, the water flow will not flow through the abutting portion, and once the lint and other impurities are intercepted on the filter rods, the water flow may be completely blocked. 6) The comb teeth of the comb tooth-shaped filtering structure in the present application are staggered, so that the comb teeth do not block each other. Since the water flow entering the lifting ribs can flow in any direction, this arrangement facilitates the flowing water flow to contact more comb teeth to achieve better filtering effect. And the extension lengths of the multiple rows of comb teeth are different, which is also for the purpose of staggering the multiple comb teeth, so that the water flow flowing in any direction in the lifting ribs can pass through more comb teeth for filtering and interception, thereby achieving better filtering effect.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the embodiments will be described in detail below with reference to the drawings of the embodiments of the present application.

[0035] Embodiment 1

[0036] A washing drum is arranged in a washing machine to hold washing water, wash clothes and discharge the washing water. A lifting rib is often arranged on the inner wall 3 of the washing drum to lift the water flow. The lifting rib comprises an outer shell 1 arranged on the inner wall 3 of the washing drum, and an inner cavity 4 formed between the outer shell 1 and the inner wall 3 of the washing drum. The lifting rib actually uses the outer shape of the outer shell 1 to achieve the effect of lifting the water flow, and the inner cavity 4 is a hollow cavity. Therefore, in order to save space, components required inside the washing machine can be arranged in the hollow cavity of the inner cavity 4. At present, a filtering structure is arranged in the space of the inner cavity 4 according to a patent. A through hole 2 is arranged on any side wall 8 of the outer shell 1 for the water flow to enter and exit, so that the water flow in the washing drum can flow into the inner cavity 4 through the through hole 2, and the water flow can be filtered by the filtering structure in the inner cavity 4. The filtered water flow can flow into the inner cavity 4 again through the through hole 2, so as to achieve the effect of filtering the water flow.

[0037] But the current in the lifting rib set filter structure of the patent, often in the lifting rib set filter screen, and filter screen has the shortcoming of easy to retain line dregs and other residues, not easy to clean, need to be replaced regularly. Therefore, the embodiment proposes a lifting rib as shown in the figure, the lifting rib is provided with a comb-shaped filter structure 14, the comb-shaped filter structure 14 is not easy to be blocked by line dregs and other residues, and is easy to clean. The comb-shaped filter structure 14 has a comb-shaped extension volume, compared with the previous planar filter screen, the comb-shaped filter structure 14 has a larger extension volume and can contact more water flow, thereby filtering more water flow entering the lifting rib and achieving better filtering effect. And the gap of the comb-shaped filter structure 14 is larger than the grid on the filter screen, and the comb-shaped filter structure 14 has a larger extension volume, so that the line dregs are not easy to cause the blockage of the comb-shaped filter structure 14 and are easier to clean.

[0038] As shown in Figure 2 、 6 , the comb-shaped filter structure 14 includes a plurality of combs 17, when the water flow containing impurities flows through the comb-shaped filter structure 14, the line dregs and other residues can be suspended on the combs 17, thereby achieving the effect of filtering residues. The combs of the comb-shaped filter structure 14 can be various shapes, as long as they are convenient for intercepting line dregs and other impurities. In the embodiment, the combs 17 are provided in the form of cylindrical rod structure, so that the combs 17 are easier to process.

[0039] In order to improve the filtering effect, the contact area of the water flow in the lifting rib with the combs 17 should be as large as possible. The water flow flows into the lifting rib from the through hole 2 provided on the side wall 8, and it is obvious that the water flow is most concentrated at the position of flowing into the lifting rib, and the water flow is largest. After entering the lifting rib, the water flow will be dispersed and flow in any direction in the lifting rib. In order to make the combs 17 contact more water flow, the combs 17 can be fixed on the side wall 8 provided with the through hole 2. As shown in Figure 3 、 6 , the combs 17 are provided on the side wall 8 provided with the through hole 2, the top of the comb 17 is connected with the inner surface 8 of the side wall 8 and extends to the inner wall 3 of the washing drum. The combs 17 are fixed on the side wall 8 provided with the through hole 2, so that the combs 17 are close to the water inlet through hole 2, thereby making the water flow just flowing into the lifting rib more concentrated. The larger water flow can directly contact the combs 17 and be filtered by the combs 17.

[0040] The water flow just entering the lifting rib through the through hole 2 can flow in any direction, but if the water flow needs to be discharged into the washing drum again through the through hole 2 during the water flow flowing in the lifting rib, the water flow will definitely form a flowing track between the shell 1 and the inner wall 3 of the washing drum. In order to make the comb teeth 17 contact the water flow flowing in the lifting rib, the comb teeth 17 can be extended to the inner wall 3 of the washing drum along the fixed side wall 8, that is, the comb teeth 17 have a certain extension distance between the shell 1 and the inner wall 3 of the washing drum. The water flow flowing in the lifting rib, which can flow into the lifting rib through the through hole 2 and flow back to the washing drum through the through hole 2, will have the possibility of contacting the comb teeth 17 and then being filtered by the comb teeth 17.

[0041] As shown in Figure 1 , 5 , the through holes 2 are arranged on the plurality of side walls 8 of the shell 1, so the comb teeth 17 can be correspondingly arranged on the plurality of side walls 8. The lifting ribs are arranged in the axial direction of the inner wall 3 of the washing drum, and the water flow in the washing drum is more likely to flow into the through holes 2 arranged on the circumferential side wall of the shell 1 when flowing to the lifting rib, so the comb teeth 17 can be fixed on the inner surface 18 of the circumferential side wall.

[0042] In order to improve the filtering effect, a plurality of comb teeth 17 can be arranged on the same side wall. When the comb teeth 17 are more, the comb teeth 17 need to be arranged so that the comb teeth 17 do not affect each other.

[0043] As shown in Figure 2 , 6 , the plurality of comb teeth 17 arranged on the same side wall 8 are uniformly distributed on the side wall 8; when the plurality of comb teeth 17 are arranged in rows, the comb teeth 17 in each row are transversely equidistantly arranged; and / or when the plurality of comb teeth 17 are arranged in columns, the comb teeth 17 in each column are longitudinally equidistantly arranged. Uniformly arranging the comb teeth 17 is more convenient for processing, and the spacing between adjacent comb teeth 17 can be better controlled. The spacing between adjacent comb teeth 17 can be set to a set value, and the user can set the set value according to the general size of the lint and other impurities. The set value is often set to be relatively small, so that the spacing between adjacent comb teeth 17 is relatively small, and the lint and other impurities are more likely to be hung on the comb teeth 17 or stuck between the two comb teeth 17. Preferably, when the through holes 2 on the same side wall 8 are arranged in rows, the plurality of comb teeth 17 are arranged in rows; and / or when the through holes 2 on the same side wall 8 are arranged in columns, the plurality of comb teeth 17 are arranged in columns. That is, because the comb teeth 17 need to be washed by the water flow flowing into the through holes 2, the arrangement of the comb teeth 17 should be consistent with the arrangement of the through holes 2; therefore, when the through holes 2 are arranged in rows, the comb teeth 17 are also arranged in rows; and when the through holes 2 are arranged in columns, the comb teeth 17 are also arranged in columns.

[0044] As shown in Figure 2As shown in FIG. 1, the plurality of comb teeth 17 arranged on the same side wall 8 are staggered in the direction of the rows of the side wall 8. That is, after the positions of the comb teeth 17 in a row are fixed, the comb teeth 17 in the adjacent rows are arranged in the gaps between the comb teeth 17 in the row. Such arrangement prevents the comb teeth 17 in the adjacent rows from blocking each other and affecting the filtering effect of the comb teeth 17. The comb teeth 17 in each row have the same length, and the comb teeth 17 in the adjacent rows have different lengths. Similarly, the comb teeth 17 in the adjacent rows have different lengths in the length direction, so that the comb teeth 17 are staggered in the length direction. When the water flow in the inner cavity 4 flows in the inner cavity 4, the water flow can flow in various directions. When the water flow flows in a direction intersecting the side wall of the comb teeth 17, the above-mentioned staggered arrangement of the plurality of rows of comb teeth 17 in the direction of the rows and in the length direction can enable the water flow intersecting the side wall of the comb teeth 17 to contact more comb teeth 17, thereby improving the filtering effect. That is, because the water flow can flow in any direction in the lifting rib, the plurality of comb teeth 17 should be staggered in as many directions as possible, so that the comb teeth 17 in various directions do not block each other, and the water flow flowing in any direction can contact as many comb teeth 17 as possible, thereby increasing the possibility of intercepting the lint and other impurities.

[0045] The lifting rib provided with the comb tooth-shaped filtering structure 14 in the embodiment is used to filter the water flow in the washing drum. Compared with the prior art of arranging a filtering screen structure in the lifting rib, the comb tooth-shaped filtering structure 14 in the embodiment has more gaps, so that the lint and other impurities are less likely to be blocked. In addition, the comb tooth-shaped filtering structure 14 in the embodiment extends a certain length, so that the comb tooth-shaped filtering structure 14 can achieve a better filtering effect than the filtering screen with a relatively small thickness.

[0046] Embodiment 2

[0047] The lifting rib provided in the embodiment is also provided with the comb tooth-shaped filtering structure 14. The difference between the comb tooth-shaped filtering structure 14 in the embodiment and the comb tooth-shaped filtering structure 14 in Embodiment 1 is that the structure of the comb teeth 17 in the comb tooth-shaped filtering structure 14 in the embodiment is different from that of the comb teeth 17 in Embodiment 1. In the embodiment, the comb teeth 17 have a structure similar to a “tree”, as shown in FIG. 2. Figure 6 As shown in FIG. 2, the comb teeth 17 include a cylindrical rod 19, and a “branch”-shaped filtering rod 20 is arranged on the cylindrical rod 19. Like Embodiment 1, the cylindrical rod 19 itself can suspend the lint and other impurities, and the adjacent cylindrical rods 19 can enable the lint and other impurities to be clamped. In addition, the “branch”-shaped filtering rod 20 arranged on the cylindrical rod 19 can also suspend the lint and other impurities, and can enable the lint and other impurities to be clamped between the cylindrical rod 19 and the filtering rod 20.

[0048] As shown in FIG. 2, the comb teeth 17 include a cylindrical rod 19, and a “branch”-shaped filtering rod 20 is arranged on the cylindrical rod 19. Like Embodiment 1, the cylindrical rod 19 itself can suspend the lint and other impurities, and the adjacent cylindrical rods 19 can enable the lint and other impurities to be clamped. In addition, the “branch”-shaped filtering rod 20 arranged on the cylindrical rod 19 can also suspend the lint and other impurities, and can enable the lint and other impurities to be clamped between the cylindrical rod 19 and the filtering rod 20. Figure 6As shown in FIG. 1, the filter rods 20 are obliquely arranged on the cylindrical rod 19, and each of the filter rods 20 extends obliquely outward from the bottom to the top along the axial direction of the cylindrical rod 19. The oblique arrangement of the filter rods 20 makes it easier for lint and other impurities to be suspended on the filter rods 20 and to be clamped between the filter rods 20 and the cylindrical rod 19, relative to the horizontal arrangement of the filter rods 20. Since the top end of the comb teeth 17 is fixed to the side wall of the outer shell 1, and the bottom end of the comb teeth 17 is closer to the inner wall 3 of the washing drum according to the extension direction of the comb teeth 17, and the water flow inside the lifting rib often needs to flow from the outer shell 1 to the inner wall 3 of the washing drum, the filter rods 20 obliquely extend outward from the bottom to the top, so that the lint and other residues in the water flow are more likely to be intercepted by the filter rods 20 as the water flow flows, thereby achieving better filtering effect. That is, the filter rods 20 gradually shrink in the direction of the water flow, making it easier for the lint and other residues to be clamped or suspended on the filter rods 20. As shown in FIG. 1, the filter rods 20 are arranged on the cylindrical rod 19 in a staggered manner. Figure 4 As shown in FIG. 1, the cylindrical rod 19 is arranged with a plurality of comb teeth 17 on different sides, and the plurality of filter rods 20 on the same side are arranged in sequence along the axial direction of the cylindrical rod 19. Arranging a plurality of comb teeth 17 on different sides of the cylindrical rod 19 can increase the expansion area of the cylindrical rod 19, thereby making it easier for lint and other impurities to be intercepted. Arranging the plurality of filter rods 20 on the same side in sequence along the axial direction can make the arrangement of the filter rods 20 more space-saving, reduce the occupied volume of the comb teeth 17, and make it less likely for adjacent comb teeth 17 to affect each other.

[0049] As can be seen from Example 1, the cylindrical rod 19 is fixed to the side wall 8 with the through hole 2, so that the cylindrical rod 19 can only be arranged staggered with the through hole 2. In fact, the water flow flows in from the through hole 2, so if the filter rods 20 are to be arranged to filter the water flow, the filter rods 20 should be extended to the position of the through hole 2, so that the water flow flowing in from the through hole 2 can directly contact the filter rods 20, thereby filtering the water flow through the filter rods 20. That is, the cylindrical rod 19 cannot be directly arranged at the through hole 2 of the side wall 8, but the filter rods 20 on the cylindrical rod 19 can be extended outward from the cylindrical rod 19, so that the filter rods 20 are directly opposite the through hole 2, thereby increasing the contact area between the water flow and the filter rods 20, and thereby improving the filtering effect of the filter rods 20. As shown in FIG. 1, the filter rods 20 extend outward from the cylindrical rod 19 to the position of the through hole 2 closest to the side wall 8 where the filter rods 20 are arranged, and the projection of the filter rods 20 on the side wall 8 with the through hole 2 covers part of the area of the through hole 2. Such an arrangement makes the filter rods 20 opposite part of the area of the through hole 2, thereby making the water flow flowing in from the through hole 2 contact the filter rods 20 and be filtered by the filter rods 20. Figure 4

[0050] As shown in FIG. 1, the filter rods 20 are obliquely arranged on the cylindrical rod 19, and each of the filter rods 20 extends obliquely outward from the bottom to the top along the axial direction of the cylindrical rod 19. The oblique arrangement of the filter rods 20 makes it easier for lint and other impurities to be suspended on the filter rods 20 and to be clamped between the filter rods 20 and the cylindrical rod 19, relative to the horizontal arrangement of the filter rods 20. Since the top end of the comb teeth 17 is fixed to the side wall of the outer shell 1, and the bottom end of the comb teeth 17 is closer to the inner wall 3 of the washing drum according to the extension direction of the comb teeth 17, and the water flow inside the lifting rib often needs to flow from the outer shell 1 to the inner wall 3 of the washing drum, the filter rods 20 obliquely extend outward from the bottom to the top, so that the lint and other residues in the water flow are more likely to be intercepted by the filter rods 20 as the water flow flows, thereby achieving better filtering effect. That is, the filter rods 20 gradually shrink in the direction of the water flow, making it easier for the lint and other residues to be clamped or suspended on the filter rods 20. As shown in FIG. 1, the filter rods 20 are arranged on the cylindrical rod 19 in a staggered manner. Figure 6 ​As shown in the figure, each filter rod 20 extends to the closest through hole 2 on the corresponding side. For example, the filter rods 20 arranged on the right side of the cylindrical rod 19 all extend to the closest through hole 2 on the right side of the filter rod 20, and the filter rods 20 arranged on the left side of the cylindrical rod 19 all extend to the closest through hole 2 on the left side of the filter rod 20. That is, the plurality of filter rods 20 on the cylindrical rod 19 respectively continue to extend outward along the respective arrangement side, so that the filter rods 20 are fully unfolded on the cylindrical rod, so that the water flow fully contacts the filter rods 20, thereby achieving a better filtering effect.

[0051] When the plurality of filter rods 20 on different sides of the comb teeth 17 all extend outward, the filter rods 20 should also be unable to contact the adjacent comb teeth 17. Specifically, all the filter rods 20 arranged on any comb tooth 17 have a gap between the comb tooth 17 and the surrounding adjacent comb teeth 17. Because when the filter rod 20 has no gap with the adjacent comb tooth 17, that is, when the filter rod 20 and the adjacent comb tooth 17 abut, the water flow at the abutting position will not be able to pass through, and at this time if the filter rod 20 also has lint and other impurities, it is more likely to cause the water flow to be completely blocked. Therefore, the filter rod 20 should maintain a gap with the adjacent comb tooth 17. The comb-tooth-shaped filter structure 14 provided in the raised rib of the present embodiment has a more reasonable design of the comb tooth 17 structure. In addition to the same cylindrical rod 19 as in Embodiment 1, each comb tooth 17 is also provided with a plurality of filter rods 20 on the cylindrical rod 19, so that the lint and other residues can also be suspended or clamped on the filter rods 20, thereby enabling the comb-tooth-shaped filter structure 14 to achieve a better filtering effect. Moreover, the arrangement of the filter rods 20 enlarges the overall area of the comb tooth 17, thereby increasing the area of the comb tooth 17 in contact with the water flow, so that more water flow passes through the filtering treatment of the comb tooth 17, improving the filtering effect.

[0052] Embodiment 3

[0053] The inner wall 3 of the washing drum is often provided with a raised rib 16 for lifting the water flow. The raised rib 16 includes an outer shell 1 arranged on the inner wall 3 of the washing drum, and an inner cavity 4 is formed between the outer shell 1 and the inner wall 3 of the washing drum. The inner cavity 4 has a certain volume, in order to fully utilize the space and save volume, the components required in the washing machine can be arranged in the inner cavity 4 of the raised rib 16. For example, for the current non-hole washing machine, there is a patent for arranging a drainage device in the inner cavity 4 of the raised rib 16. The non-hole washing machine usually has a drainage port 6 on the inner wall 3 of the washing drum, each raised rib 16 covers at least one drainage port 6, and a drainage valve 15 for blocking the drainage port 6 is arranged in the inner cavity 4 of the raised rib 16 at the position of the drainage port 6. The effect of controlling the opening and closing of the drainage port 6 can be achieved by controlling the drainage valve 15. In this way, by using one washing drum, the drainage port 6 can be controlled to be closed, so that the washing machine can be filled with water and washed; the drainage port 6 can be controlled to be opened for drainage. That is, only one washing drum is arranged, and the entire washing process of the washing drum, such as water filling, washing, spinning, and drainage, can be realized.

[0054] And the other washing machine components such as filter device can be set in the lifting rib 16, but the setting of other washing machine components can affect the work of the drainage device. In view of the above technical problems, the present application provides a lifting rib structure, the internal structure of the lifting rib is reasonable, so that multiple components required in the washing machine can be arranged in the lifting rib, and the multiple components will not affect each other.

[0055] To solve the above technical problems, the present application provides a lifting rib 16 as shown in the figure. The inner cavity 4 of the lifting rib 16 of the present application includes two independent parts: a filter space 21 and a drainage space 35. The filter space 21 is used to filter the water flow in the washing drum, and the drainage space 35 is used to drain the water in the washing drum. The housing 1 is provided with a through hole 2 which can exchange with the water flow in the washing drum, and the filter space 21 covers the through hole 2 provided on the housing 1, that is, the filter space 21 can exchange with the water flow in the washing drum, that is, the filter space 21 filters the water flow in the washing drum flowing into the filter space 21, and drains the filtered clean water flow back into the washing drum 5. The inner wall 3 of the washing drum is provided with a drainage port 6 for draining water in the washing drum, and the drainage space 35 covers at least one drainage port 6, and the drainage space 35 can guide the water in the washing drum to the drainage port 6 opened on the inner wall 3 of the washing drum to achieve the effect of drainage.

[0056] As shown in Figure 7 , 3 The drainage valve 15 is arranged at the drainage port 6 to control the on-off of the water flow of the drainage port 6. The drainage valve 15 includes a liftable valve core which can correspond to block the drainage port 6. That is, as shown in the figure, when the valve core is lowered, the drainage port 6 is blocked, so that the water flow cannot be discharged from the drainage port 6; when the valve core is raised, the valve core no longer blocks the drainage port 6, so that the water flow can be discharged from the drainage port 6. The lifting of the valve core is realized by the counterweight structure 23 connected with the valve core to drive the lifting of the valve core. That is, the counterweight structure 23 itself can be lifted and has a large gravity, and the lifting of the counterweight structure 23 can drive the lifting of the valve core connected with it.

[0057] The drainage space 35 is further divided into two independent installation cavity 22 and drainage cavity 36. The installation cavity 22 is a closed chamber where water flow cannot enter, and the counterweight structure 23 and part of the structure of the drain valve 15 are arranged in the installation cavity 22, so that the lifting movement of the counterweight structure 23 is not affected by the water flow. For example, when the water flow in the washing drum has impurities such as lint, if the water flow enters the installation cavity 22, it will cause the lint and other impurities to possibly wrap around the counterweight structure 23, which may affect the normal lifting of the counterweight structure 23, and further cause the valve core to fail to accurately reach the set position and accurately control the water flow of the drain port 6. Therefore, the installation cavity 22 where the counterweight structure 23 is installed should be a closed chamber where water flow cannot enter. The drainage space 35 should also include a drainage cavity 36 where water flow is discharged, and the other structures of the drain valve 15 that are not arranged in the installation cavity 22 and the drain port 6 are arranged in the drainage cavity 36. The drainage cavity 36 should be able to allow the water in the washing drum to flow in and be discharged from the drain port 6 due to its drainage effect, so the drainage cavity 36 is arranged as an open cavity.

[0058] Or when the drain valve 15 is a valve driven by moving against other structures, such as when the drain valve 15 is a solenoid valve, the components that may be affected by water flow, such as solenoid components, can be arranged in the installation cavity 22, and the other devices of the drain valve 15 can be arranged in the drainage cavity 36.

[0059] As shown in Figure 7 , 8 From the working principle of the above-mentioned drain valve 15, it can be seen that the drain valve 15 should be arranged in the axial direction of the drain port 6, and the end of the drain valve 15 away from the drain port 6 is connected to the counterweight structure 23. When the counterweight structure 23 of the drain valve 15 is lowered, it can drive the valve core to descend, and further make the valve core block the drain port 6, which is sealed; when the counterweight structure 23 of the drain valve 15 is raised, it drives the valve core to rise, and further makes the water flow discharge from the drain port 6. As shown in the figure, the installation cavity 22 and the drainage cavity 36 are arranged in the axial direction of the drain port 6, from far to near. As mentioned above, the counterweight structure 23 is arranged at the end of the drain valve 15 away from the drain port 6, so the installation cavity 22 containing the drain valve 15 should be arranged at a position away from the drain port 6 in the axial direction of the drain port 6. That is, the installation cavity 22 and the drainage cavity 7 can be arranged as shown in the figure, up and down.

[0060] As described above, in order to prevent the water flow in the washing drum from flowing into the installation cavity 22, the installation cavity 22 should be provided as a closed cavity. As discussed above, the installation cavity 22 should be provided in the drainage space 35 away from the side of the drainage port 6 provided on the inner wall 3 of the washing drum, and the outer shell 1 is away from the inner wall 3 of the washing drum, so the installation cavity 22 can be enclosed by the outer shell 1. Specifically, as shown in the drawings, the installation cavity 22 is a closed cavity connected to the outer shell 1; including a plurality of installation cavity side walls 24 extending from the outer shell 1 to the inner wall 3 of the washing drum, and an installation cavity bottom wall 25 connected to the bottom end surface of all installation cavity side walls 24. The installation cavity bottom wall 25 is provided with a mounting through hole 26 at a position opposite to the drain valve 15, and the drain valve 15 is partially embedded in the mounting through hole 26 and penetrates into the installation cavity 22 through the mounting through hole 26, and the part of the drain valve 15 penetrating into the installation cavity 22 is connected to the counterweight structure 23. In order to ensure the sealing, a sealing structure can also be provided at the position of the mounting through hole 26 to prevent water leakage at the mounting through hole 26.

[0061] As shown in Figure 7 , 8 , a limiting groove 27 is provided on the installation cavity bottom wall 25 to limit the falling limit position of the counterweight structure 23, and the counterweight structure 23 embedded in the limiting groove 27 falls to the limit position. The counterweight structure 23 can be lifted and lowered, and the counterweight structure 23 falls under the action of centrifugal force, and when the counterweight structure 23 falls to the set position, the drainage port 6 will be unblocked. In order to ensure the sealing when the drainage port 6 is blocked, the falling limit position of the counterweight structure 23 should be limited, and the falling position of the valve core corresponding to the counterweight structure 23 when moving to the falling limit position is limited, and the valve core is moved to the position required to block the drainage port 6. The limiting groove 27 is provided on the installation cavity bottom wall 25, and the limiting groove 27 can be embedded with the part of the counterweight structure 23 falling to the limit position, so that the counterweight structure 23 will be embedded and limited once it falls to the limiting groove 27. When the drainage port 6 is blocked, the counterweight structure 23 is moved to the position of the limiting groove 27, and the valve core is limitedly moved to the position of the drainage port 6, thereby achieving good blocking of the drainage port 6.

[0062] As shown in Figure 7 , 8As shown in the figure, the fixing groove 28 is arranged on the bottom wall 25 of the mounting cavity, the inner wall of the fixing groove 28 is consistent with the part of the outer shape of the drain valve 15, and the drain valve 15 is partially embedded in the fixing groove 28. The bottom end surface of the bottom wall 25 of the mounting cavity is provided with the fixing groove 28 which protrudes from the mounting cavity bottom wall 25 to the outer shell 1, the inner wall of the fixing groove 28 is consistent with the part of the outer shape of the drain valve 15, and part of the structure of the drain valve 15 can be embedded in the fixing groove 28. Through the arrangement of the fixing groove 28, the drain valve 15 can be limited and fixed, thereby ensuring that the drain valve 15 moves along the direction defined by the fixing groove 28. Specifically, the fixing groove 28 has a cylindrical groove structure, which can be embedded in the valve core of the drain valve 15, thereby enabling the valve core to lift along the cylindrical groove structure during lifting.

[0063] Since the lower part of the mounting cavity 22 in the drain space 35 is the drain cavity 36, the bottom wall of the mounting cavity 22 needs to form a water inlet gap 37 with the inner wall 3 of the washing drum, and the water inlet gap 37 is in communication with the inside of the washing drum. That is, through the arrangement of the water inlet gap 37, the water flow in the inside of the washing drum can enter the drain cavity 36, and then be discharged from the drain cavity 36. Since the lifting rib 16 itself needs to be installed on the inner wall 3 of the washing drum, the position of the lifting rib 16 close to the inner wall 3 of the washing drum needs to be provided with a bottom plate, and the bottom plate is fixed on the inner wall 3 of the washing drum. Preferably, in order to save materials, the bottom plate of the lifting rib 16 and the mounting cavity bottom wall 25 of the mounting cavity 22 are arranged as one plate, as shown in Figures 7-9 As shown in the figure, the bottom of the mounting cavity bottom wall 25 of the mounting cavity 22 between the mounting cavity side walls 24 of the mounting cavity 22 can abut against the inner wall 3 of the washing drum, that is, the part of the mounting cavity bottom wall 25 surrounding the mounting cavity 22 abuts against the inner wall 3 of the washing drum, and there is no gap between the mounting cavity bottom wall 25 at the position and the inner wall 3 of the washing drum, so as to ensure that the water in the washing drum does not flow into the mounting cavity 22 and ensure the sealing of the mounting cavity 22. As shown in Figure 5 As shown in the figure, the part of the mounting cavity bottom wall 25 outside the mounting cavity 22 can be arranged as a structure not completely abutting against the inner wall 3 of the washing drum, and the mounting cavity bottom wall 25 has a water inlet gap 37 with the inner wall 3 of the washing drum, so that the water flow in the washing drum can flow into the drain cavity 36 through the water inlet gap 37. As shown in the figure, the area between the mounting cavity bottom wall 25 of the mounting cavity 22 and the inner wall 3 of the washing drum in the drain space 35 constitutes the drain cavity 36. The washing drum water flowing through the water inlet gap 37 can be discharged through the drain device in the drain cavity 36. That is, the arrangement of the drain cavity 36 can make the water in the washing drum flow into the drain cavity 36 through the water inlet gap 37 and finally be discharged at the drain port 6.

[0064] As shown in Figure 7 , 8As shown in the figure, the filter space 21 is a space connected with the outer shell 1, and the filter structure 26 is arranged in the filter space 21. The outer shell 1 is provided with a plurality of through holes 2 for water to flow in and out. Through the arrangement of the through holes 2, the water in the washing drum can flow into the filter space 21 through the through holes 2 and be filtered in the filter space 21. The filter space 21 can be a closed space, so that the water in the washing drum flowing into the through holes 2 on the outer shell 1 can be filtered in the filter space 21 and finally discharged into the washing drum again through the through holes 2, achieving the effect of filtering the water in the washing drum. Or the filter space is an open space, and an opening 10 is arranged in communication with the drain cavity 36; and then the filtered sewage in the filter space 21 can be discharged through the drain opening 6.

[0065] As shown in the figure, Figure 7 , 8 As shown in the figure, the filter space 21 is surrounded by the filter space side wall 29 and the filter space bottom wall 30, and the filter space side wall 29 extends from the outer shell 1 to the inner wall 3 of the washing drum. When the filter space 21 is a closed structure, the filter space bottom wall 30 is connected with the bottom end surface of all the filter space side walls 29, that is, the filter space bottom wall 30 and the filter space side wall 29 together form a closed structure. When the filter space 21 has an opening 10, the filter space bottom wall 30 is connected with the bottom end surface of all the filter space side walls 29 except the filter space side wall 29 closest to the drain opening 6. The filter space side wall 29 closest to the drain opening 6 has a gap 31 with the filter space bottom wall 30, and the gap 31 forms the opening 10. That is, when the filter space 21 is not closed, the opening 10 can be formed directly through the gap 31 between the filter space side wall 29 and the filter space bottom wall 30, so that the filtered sewage can flow to the drain cavity 36 through the opening 10 for discharge.

[0066] The filter space 21 and the drainage space 35 in the inner cavity 4 of the lifting rib 16 are two independent spaces, which can be arranged at will, but in order to save space and make the structure in the inner cavity 4 compact, the filter space 21 and the drainage space 35 can be arranged adjacent to each other. As known from the foregoing, the mounting cavity 22 in the filter space 21 and the drainage space 35 is arranged in connection with the shell 1, so as to save space, the mounting cavity 22 can be arranged adjacent to the filter space 21. In order to save materials, the mounting cavity 22 and the filter space 21 have a common side wall 32, the common side wall 32 extends from the shell 1 to above the inner wall 3 of the washing drum, and the mounting cavity bottom wall 25 of the mounting cavity 22 is connected with the bottom end surface of the common side wall 32. The common side wall 32 does not abut against the inner wall 3 of the washing drum, so that the filter space 21 can use the gap between the common side wall 32 and the inner wall 3 of the washing drum as the opening 10 for draining water to the drainage cavity 36. And the common side wall 32 does not abut against the inner wall 3 of the washing drum, so that the area between the mounting cavity bottom wall 25 of the mounting cavity 22 and the inner wall 3 of the washing drum just constitutes the space of the drainage cavity 36, and most of the structure of the drainage valve 15 is arranged in the space of the drainage cavity 36.

[0067] As shown in the drawings, the adjacent filter space 21 is arranged in the hollow position in the lifting rib 16, and the drainage space 35 in the lifting rib 16 is arranged outside the filter space 21. The fixing device for fixing the lifting rib 16 is arranged outside the drainage space 35 and the filter space 21. The fixing device is arranged outside the drainage space 35 and the filter space 21, so that when the lifting rib 16 is installed, the installation of the fixing device will not affect the filter space 21 and the drainage space 35. The fixing device includes a mounting hole 33 arranged on the inner wall 3 of the washing drum and a positioning column 34 inserted into the mounting hole 33, so that when the lifting rib 16 is installed, the positioning column 34 can be inserted into the mounting hole 33 to preliminarily position the lifting rib 16. Then the lifting rib 16 can be fastened to the inner wall 3 of the washing drum by screws or the like.

[0068] The lifting rib 16 provided by the present application comprises the independent drainage space 35 and the filter space 21, so that the filter space 21 of the lifting rib 16 can filter the water in the washing drum, and the drainage space 35 of the lifting rib 16 can drain the water in the washing drum. And due to the reasonable arrangement of the filter space 21 and the drainage space 35, they do not affect each other.

[0069] Example 4

[0070] The lifting ribs provided on the inner wall of the washing drum are used to lift water flow. Currently, there are patents that can introduce water in the washing drum into the lifting ribs, and filter the water in the washing drum by providing a filter structure in the lifting ribs. However, the lifting ribs provided with the filter structure can only collect the filtered lint and other impurities in the lifting ribs, and the lifting ribs need to be cleaned regularly to remove the impurities. This will result in that the filter structure provided in the lifting ribs may have more lint and other impurities remaining on it after long-term use, which will affect the filtering effect of the filter structure. The filter structure in the lifting ribs cannot be self-cleaned, and the filter structure needs to be cleaned regularly, which is troublesome. In view of the above technical problems, the present application provides a lifting rib structure 16, and the filter structure 5 in the lifting rib 16 can be self-cleaned, and the filter structure 5 can be kept clean and the filtering effect can be ensured without manually cleaning the filter structure 5.

[0071] The lifting rib 16 provided by the present embodiment includes a shell 1 provided on the inner wall 3 of the washing drum, the shell 1 constitutes the outer contour of the lifting rib 16, and the shell 1 and the inner wall 3 of the washing drum constitute an inner cavity 4, which is the internal space of the lifting rib 16. The shell 1 is provided with a through hole 2 for water flow, so that the water in the washing drum can flow into the inner cavity 4 of the lifting rib 16 through the through hole 2, and the water flow in the inner cavity 4 of the lifting rib 16 can flow out of the inner cavity 4 through the through hole 2. The filter structure 5 is provided in the inner cavity 4, so that the water flowing through the inner cavity 4 of the lifting rib 16 can be filtered by the filter structure 5. The inner wall 3 of the washing drum is provided with a plurality of drain holes 6 for draining water in the washing drum, and the inner cavity 4 covers at least one drain hole 6. Such arrangement makes the water flow into the inner cavity 4 of the lifting rib 16 through the through hole 2, and then the water in the washing drum flowing into the inner cavity 4 is drained through the drain hole 6. That is, the drain flow in the washing drum includes a drain path flowing from the through hole 2 to the drain hole 6. Since the inner cavity 4 covers at least one drain hole 6, the inner cavity 4 at least includes one of the above-mentioned drain paths, and the filter structure 5 is provided in the inner cavity 4, so that the drain path can pass through the filter structure 5 in the inner cavity 4. In this way, the filter structure 5 can be washed by the drain water flowing according to the drain path, so as to remove the lint and other impurities remaining on the filter structure 5, and achieve the effect of cleaning the filter structure 5.

[0072] As shown in the figure, the drain port 6 is provided with a drain valve 15 for controlling the communication or isolation of the drain port 6 and the inner cavity 4. When the drain valve 15 controls the communication of the drain port 6 and the inner cavity 4, the inner cavity 4 can be communicated with the drain port 6, and a drain water flow formed by the through hole 2 flowing to the drain port 6 to drain the water in the washing drum is formed in the inner cavity 4. The filter structure 5 is arranged at a position where the drain water flow flows through, so that the drain water flow can wash the filter structure 5 and wash away the impurities such as thread scraps remaining on the filter structure 5, thereby achieving the effect of cleaning the filter structure 5. When the drain valve 15 controls the isolation of the drain port 6 and the inner cavity 4, the inner cavity 4 forms a closed structure except the through hole 2, and a washing water flow formed by the through hole 2 flowing in and out of the inner cavity 4 reciprocally with the washing drum is formed in the inner cavity 4. With the rotation of the washing drum during washing, the through hole 2 will rotate to different positions, and the water in the washing drum is easy to flow into the inner cavity 4 when the through hole 2 is at some positions, and the water in the inner cavity 4 is easy to flow to the washing drum when the through hole 2 is at some positions. That is, the water reciprocally flows between the washing drum and the inner cavity 4, achieving the effect of repeatedly washing the inner cavity 4 and forming the washing water flow. The filter structure 5 is arranged at a position where the washing water flow flows through in the inner cavity 4, so that the washing water flow is subjected to the filtering treatment of the filter structure 5 during washing, achieving the effect of filtering the water in the washing drum. As shown in the figure, the drain valve 15 is arranged above the drain port 6, and whether the water flow is drained from the drain port 6 is controlled by controlling whether the drain port 6 is communicated with the inner cavity 4, and the drain valve 15 can also be arranged below the drain port 6 to directly control whether the water flow at the drain port 6 can flow outside the washing drum wall.

[0073] As Figures 2-4As shown in the figure, the filtering structure 5 includes filtering screen 13, comb-tooth filtering structure 14 and other filtering structures. In order to enable the water in the washing drum to wash the filtering structure 5 and pass through the filtering process of the filtering structure 5, the filtering structure 5 should be reasonably arranged in the inner cavity 4, which is beneficial to the filtering process of the filtering structure 5 and the removal of the residual lint and other impurities. The filtering structure 5 includes filtering section 12 which intercepts the impurities in the water flow. After the filtering process, the impurities will be attached to the filtering section 12. In order to ensure the filtering effect of the filtering structure 5, the washing water flow should flow through the filtering section 12. When the filtering structure 5 is washed by the drainage water flow, the drainage water flow should also flow through the surface of the filtering section 12 to remove the residual lint and other impurities. As shown in the figure, the filtering section 12 can be the cross section of the filtering screen 13 or the cross section of the comb-tooth filtering structure 14 which can intercept the lint and other impurities. As shown in the figure, each row of comb-tooth protrusions forms a plane which is parallel to the side wall 8 of the setting through hole 2 and intercepts the impurities. The cross section of the filtering structure is used as the filtering section 13 to intercept the lint and other impurities. The water flow direction in the inner cavity 4 at the position of the filtering section 12 forms an angle with the filtering section 12. In this way, the washing water flow and the drainage water flow will definitely flow through the filtering section 12, so that the washing water flow passes through the filtering process of the filtering section 12 and the drainage water flow can remove the residual lint and other impurities on the surface of the filtering section 12. Preferably, the water flow direction in the inner cavity 4 at the position of the filtering section 12 is perpendicular to the filtering section 12. Preferably, the washing water flow and the drainage water flow are perpendicular to the filtering section 12, so that the contact area of the washing water flow and the drainage water flow with the filtering section 12 is the largest, which is more beneficial to the filtering of the washing water flow and the removal of the impurities by the drainage water flow. The plane which intercepts the impurities can be removed by the drainage water flow, so the washing water flow and the drainage water flow at the position of the filtering section 13 intersect with the filtering section 13. If it is other type of filtering structure 5, the drainage water flow and the washing water flow should also flow through the position of the filtering section 12.

[0074] More preferably, the filtering section 12 is arranged parallel to the side wall 8 on which the through holes 2 are arranged for water inlet. Since the through holes 2 are arranged on the side wall 8 for water inlet, the filtering section 12 is arranged parallel to the side wall 8 so that the water flow entering through the through holes 2 on the side wall 8 is perpendicular to the filtering section 12. And no matter whether it is the above-mentioned flushing water flow or the drainage water flow, the water flow enters the inner cavity 4 through the through holes 2. The filtering section 12 is arranged parallel to the side wall 8 on which the through holes 2 are arranged, so that the drainage water flow entering the inner cavity 4 is easier to flush the filtering section 12, and the flushing water flow entering the inner cavity 4 can be filtered. The filtering section 12 is projected to the side wall 8, and the projection covers at least part of the through holes 2 on the side wall 8; preferably, the projection covers all the through holes 2 on the side wall 8. In this way, the water flow entering through the through holes 2 on the side wall 8 can flow to the filtering section 12. That is, for the filter screen 13, the filter screen 13 needs to be arranged parallel to the side wall 8, so that the drainage water flow flowing through the through holes 2 on the side wall 8 can directly flow to the filter screen 13, achieving the effect that the flushing water flow is filtered by the filter screen 13 and the drainage water flow flushes the filter screen 13.

[0075] More preferably, as shown in the drawings, the filtering section 12 is arranged close to the side wall 8 in the filtering cavity 7. Since the through holes 2 for water inlet are arranged on the side wall 8, the filtering section 12 is arranged close to the side wall 8, that is, close to the through holes 2 for water inlet. The water flow entering the inner cavity 4 is certainly greater close to the water inlet, so arranging the filtering section 12 close to the through holes 2 for water inlet can make the filtering section 12 obtain a greater flushing water flow, thereby facilitating the cleaning of the thread scraps and other impurities remaining on the filtering structure 5. And the water flow is the greatest at the position of the through holes 2, arranging the filtering section 12 close to the side wall 8 on which the through holes 2 are arranged can make the filtering section 12 filter more water flow entering the inner cavity 4, thereby achieving a better filtering effect. The lifting ribs 16 extend axially along the washing drum, the through holes 2 are arranged on the circumferential two sides of the lifting ribs 16, and the filtering structure 5 is arranged close to the through holes 2.

[0076] Specifically as Figures 2-4As shown in the drawings, the guide wall 9 is arranged in the lifting rib 16 to guide the flow of the drainage water and the washing water, the guide wall 9, the side wall 8 of the through hole 2 of the outer shell 1, and the inner wall 3 of the washing drum form the filtering cavity 7, the filtering cavity 7 covers at least part of the through hole 2 on the side wall 8, and the filtering structure 5 is arranged in the filtering cavity 7. That is, the filtering cavity 7 connects the through hole 2 of the outer shell 1 and the drainage port 6 on the inner wall 3 of the washing drum to drain the water in the washing drum. In addition, the filtering structure 5 is arranged in the filtering cavity 7. When the water in the inner drum of the washing machine flows along the filtering cavity 7, the filtering structure 5 in the filtering cavity 7 can be cleaned. The position and structure of the lifting rib 16 on the inner wall 3 of the washing drum in the embodiment are reasonable, so that the inner cavity 4 of the lifting rib 16 can form the filtering cavity 7 for guiding the flow of the drainage water and the washing water. The washing water can flow through the filtering structure 5 under the guidance of the filtering cavity 7 and be filtered by the filtering structure 5. The drainage water can flow through the filtering structure 5 under the guidance of the filtering cavity 7. In this way, the filtering structure 5 can be automatically cleaned by the water flow for drainage in the washing drum.

[0077] As described above, the drainage water in the filtering cavity 7 is the water supply for cleaning the filtering structure 5, and the water flow in the filtering cavity 7 should be sufficient when draining. Therefore, a partition type structure can be arranged in the inner cavity 4 of the lifting rib 16, the partition type structure can form the filtering cavity 7, so that the filtering cavity 7 with the partition type structure can make the drainage flow along the set track, thereby controlling the water flow to flow through the structure 5 better. As shown in the drawings, the outer shell 1 of the lifting rib 16 includes a plurality of side walls 8, and a plurality of through holes 2 are arranged on the side walls 8. Two guide walls 9 are connected to the side walls 8 to form the filtering cavity 7, and the guide walls 9 can be perpendicular to the side walls 8 and extend from the side walls 8 to the inner wall 3 of the washing drum. The area between the guide walls 9 on the side walls 8 covers at least part of the through holes 2 on the side walls 8, and the filtering structure 5 is arranged between the two guide walls 9. Preferably, the area between the guide walls 9 covers all the through holes 2 on the side walls 8. The guide wall 9 is a partition type guide structure. Through the limitation of the guide wall 9, the drainage water and the washing water can only flow in the area between the guide walls 9. If the flow range of the drainage water is too wide, the drainage water will be too divergent, and the impact force of the drainage water will be insufficient, which will affect the cleaning effect of the filtering structure 5.

[0078] The specific structure of the filter cavity 7 provided by the flow guide side wall 9 is divided into two types. One is when the drain port 6 on the inner wall 3 of the washing drum is located between the flow guide side walls 9, and the other is when the drain port 6 on the inner wall 3 of the washing drum is located outside the flow guide side walls 9. When the drain port 6 is located between the flow guide side walls 9, the flow guide side wall 9 is extended from the side wall 8 to abut the inner wall 3 of the washing drum, that is, the flow guide side wall 9 penetrates the side wall 8 and the inner wall 3 of the washing drum. Since the drain port 6 is located between the two flow guide side walls 9 on the inner wall 3 of the washing drum, the flow guide side wall 9, the side wall 8, and the inner wall 3 of the washing drum form a filter cavity 7 that is closed except for the through hole 2 and the drain port 6. The filter structure 5 is arranged in the filter cavity 7, so that the water flow is guided to form a drain water flow and a flushing water flow, and the drain water flow flows through the filter structure 5 to clean the filter structure 5, and the flushing water flow flows through the filter structure 5 and is filtered.

[0079] When the drain port 6 is located outside the flow guide side wall 9, the flow guide side wall 9, the side wall 8, and the inner wall 3 of the washing drum cannot form the above-mentioned closed filter cavity 7, because this will make the drain water flow unable to flow into the drain port 6. Therefore, at least an opening 10 is needed in the filter cavity 7, so that the drain water flow can flow into the drain port 6 from the opening 10. As shown in Figure 2 、 4 , one of the flow guide side walls 9 near the drain port 6 has a gap with the inner wall 3 of the washing drum, and the gap forms an opening 10 for the water flow in the inner cavity 4 to flow to the drain port 6; the rest of the flow guide side walls are arranged to extend from the side wall 8 to abut the inner wall 3 of the washing drum. That is, one of the flow guide side walls near the drain port 6 extends from the side wall 8 to the inner wall 3 of the washing drum, but does not extend to abut the inner wall 3 of the washing drum, but has a gap with the inner wall 3 of the washing drum, and the gap forms an opening 10, so that the drain water flow can flow out from the opening 10 and finally flow to the drain port 6. Of course, the flow guide side wall 9 can also be arranged to extend from the side wall 8 to abut the inner wall 3 of the washing drum, and an opening 10 is arranged on one of the flow guide side walls near the drain port 6. The side wall 8, the inner wall 3 of the washing drum, and the flow guide side wall 9 form a filter cavity 7 with the opening 10, and the filter structure is arranged in the filter cavity 7; so that the water flow is better guided to form a drain water flow, and the drain water flow flows through the filter structure 5 to clean the filter structure 5.

[0080] Since the water flow in the filtering cavity 7 needs to flow to the drain port 6 finally, a guide plate 11 can be arranged in the filtering cavity 7 to guide the water flow to the drain port 6. The arrangement of the guide plate 11 makes the water flow in the filtering cavity 7 easy to gather to the drain port 6, so that the water flow to the drain port 6 is larger, and the water flow containing the wire scraps and other impurities after the filter structure 5 is cleaned can flow to the drain port 6 and be drained under the guidance of the guide plate 11. Since the water flow contains the wire scraps and other impurities after the filter structure 5 is cleaned, the arrangement of the guide plate 11 can make the water flow more gathered, so that the water flow to the drain port 6 is larger, and the wire scraps and other impurities are more easily drained from the drain port 6.

[0081] Specifically as shown in Figure 2 、 4 The bottom of the filtering cavity 7 is provided with the guide plate 11 which is inclined downward to the drain port 6 from the guide side wall 9. The inclined structure of the guide plate 11 is more conducive to the water flow flowing to the drain port 6 along the inclined guide plate 11, and the inclined structure of the guide plate 11 can improve the flow rate of the water flow, which is more conducive to washing away the wire scraps and other impurities in the water flow. Since the drain port 6 can be arranged between the guide side walls 9 or outside the guide side walls 9, the guide plate 11 which guides the water flow to the drain port 6 also has two structures. When the drain port 6 is arranged between the guide side walls 9, the guide side walls 9 are respectively provided with the guide plate 11 which is inclined to the drain port 6. All the guide plates 11 form a conical surface with the tip pointing to the drain port 6.

[0082] The conical surface formed by the inclined guide plate 11 makes the cross-sectional area of the water flow to the drain port 6 gradually decrease, so that the flow rate of the water flow to the drain port 6 accelerates, which is more conducive to the water flow containing the wire scraps being drained from the drain port 6. When the drain port 6 is arranged outside the guide side walls 9, as mentioned above, an opening 10 needs to be arranged on a guide side wall close to the drain port 6, which causes the water flow in the filtering cavity 7 to be guided to flow to the side where the opening 10 is arranged, i.e. the water flow needs to be deviated to flow to the guide side wall where the opening 10 is arranged. Therefore, the part of the guide side wall far from the drain port 6 and above the opening 10 is provided with the guide plate 11 which is inclined to the opening 10, so that the water flow is guided to flow to the drain port 6 and be drained by the arrangement of the guide plate 11. After the guide plate 11 is arranged, the side wall 8, the inner wall 3 of the washing drum, the two guide side walls 9 and the guide plate 11 together form the filtering cavity 7, and the filter structure is arranged in the filtering cavity 7. The arrangement of the filtering cavity 7 can better guide the water flow, so that the filter structure 5 in the filtering cavity 7 can be better washed by the water flow.

[0083] The lifting rib 16 provided by the embodiment has a reasonable internal structure, so that the washing water flowing into the lifting rib 16 can be filtered by the filtering structure 5; the drainage water can clean the filtering structure 5 in the lifting rib 16, so as to clean the residual lint and other impurities on the filtering structure 5, and ensure the filtering effect of the filtering structure 5. That is, the filtering structure 5 in the lifting rib 16 can be self-cleaned, so that the filtering structure 5 does not need to be cleaned by human, and the self-cleaning of the filtering structure 5 can be realized by using the drainage in the washing drum.

[0084] Embodiment 5

[0085] The embodiment provides a non-porous washing machine based on the above-mentioned embodiments. The non-porous washing machine is usually provided with a washing drum, so that the functions of introducing washing water, washing by using the washing water and draining the washing water for spinning can be realized by one washing drum. The non-porous washing machine is provided with a drainage port 6 on the inner wall 3 of the washing drum, and a drainage valve 15 is arranged at the drainage port 6, so that the opening and closing of the water flow at the drainage port 6 can be controlled by using the drainage valve 15. By arranging the drainage valve 15, the effect that the drainage port 6 is isolated from the washing drum during the water inletting and washing process and the washing drum is closed and the water flow cannot flow out of the washing drum can be realized. During the water inletting and washing process, the above-mentioned washing water flow is formed, so that the filtering structure 5 can filter the washing water flow. The drainage valve 15 can be used to control the communication between the drainage port 6 and the washing drum, so that during the drainage and spinning process, the water flow in the washing drum is drained from the drainage port 6, and during the normal drainage of the non-porous washing machine, the drainage water flow for washing the filtering structure 5 can be formed, so that the effect of cleaning the filtering structure 5 can be achieved. That is, the non-porous washing machine can use the drainage to clean the filtering structure 5 in the lifting rib 16, so as to ensure the filtering effect.
