Description

TECHNICAL FIELD

[0001] The present application relates to the field of washing machines, in particular, to a lifting rib structure and a clothes processing device. BACKGROUND

[0002] The lifting rib is often needed to be arranged in the washing drum to lift the water flow in the washing drum. At present, there are patents that arrange a filter structure in the lifting rib to filter the lint and other impurities in the washing water. However, the filter structure arranged in the lifting rib often stores the filtered impurities in the lifting rib, and when the lint and other impurities accumulate to a certain amount, the impurities need to be manually taken out. Or some patents disclose that a drain port is arranged on the shell of the lifting rib, and a filter screen is arranged at the drain port. When the water in the lifting rib is controlled to be drained out of the drain port, the water flow in the lifting rib flowing to the washing drum is filtered by the filter screen, so as to ensure the cleanliness of the water flow flowing into the washing drum. However, such arrangement causes the lint and other impurities generated by the filtration to be suspended on the filter screen, and the filter screen needs to be regularly replaced or cleaned.

[0003] In summary, the filter structure arranged in the lifting rib at present cannot achieve the self-cleaning effect, and needs to be regularly cleaned or replaced. Therefore, a lifting rib structure is needed, and the filter structure arranged in the lifting rib can achieve the self-cleaning effect.

[0004] In view of the above problems, the present application is proposed. SUMMARY

[0005] The application aims to provide a lifting rib structure, which can filter the water flow in the washing drum and automatically discharge the filtered impurities, so as to achieve the self-cleaning effect of the filter structure. The application also aims to provide a clothes processing device, which can filter the impurities by the lifting rib and make the filter structure self-cleaned when draining water.

[0006] The present application provides a lifting rib structure, which comprises a shell, the shell is fixed on the inner wall of a washing drum and forms an inner cavity with the inner wall of the washing drum, a through hole is arranged on the shell and communicates with the washing drum, a filter structure is arranged in the inner cavity to filter the water flowing into the through hole, the inner cavity communicates with a drain port of the washing drum, and a drain water flow formed by the water flowing through the filter structure from the through hole and flowing to the drain port is formed in the inner cavity to flush the filter structure. The through hole for water inlet is arranged on the lifting rib, and at least one drain port is covered, so that the filter structure in the lifting rib can filter the water in the washing drum, and the drain water flow formed by the water flowing from the through hole to the drain port and flowing through the filter structure can be generated in the lifting rib. The drain water flow can flush the filter structure, so as to achieve the self-cleaning effect of the filter structure and ensure the filtering effect of the filter structure.

[0007] Further, the drain port is provided with a drain valve for controlling the opening and closing of the drain port; when the drain port is connected, a drain flow is formed in the inner cavity; when the drain port is disconnected, a washing flow is formed in the inner cavity, which reciprocally flows between the washing tub and the through hole. The filter structure is arranged in the inner cavity, at the position where the drain flow and the washing flow pass. By arranging the drain valve, when the drain hole is not connected with the inner cavity, the washing flow reciprocally flowing between the washing tub and the washing flow can be formed in the inner cavity, and the filter structure is arranged in the washing flow, so that the washing flow can be filtered, thereby reducing the content of impurities such as lint in the water flow in the washing tub. When the drain valve controls the connection between the drain hole and the inner cavity, the drain flow from the through hole to the drain hole is formed in the inner cavity, and the filter structure is arranged in the drain flow, so that the filter structure can be washed by the drain flow, thereby self-cleaning the filter structure.

[0008] Further, the filter structure includes a filter section for intercepting impurities in the water flow, and an angle is formed between the water flow direction of the drain flow and the washing flow passing through the filter section position and the filter section; preferably, the water flow direction of the drain flow and the washing flow passing through the filter section position is perpendicular to the filter section. The water flow direction of the drain flow and the washing flow passing through the filter section position forms an angle with the filter section, so that the drain flow and the washing flow contact the filter section, thereby filtering the washing flow by the filter structure; and the filter structure is washed by the drain flow, thereby removing the residual lint and other impurities on the filter section.

[0009] Further, the lifting rib extends along the axial direction of the washing tub, the through hole is arranged on both sides of the lifting rib, and the filter structure is arranged close to the through hole. Since both the washing flow and the drain flow enter the inner cavity from the through hole, the filter structure is arranged close to the through hole, so that the filter structure is close to the water source of the washing flow, thereby contacting more water flow and filtering more water flow; the filter structure is close to the water source of the drain flow, so that the filter structure is washed by the large water flow, thereby facilitating the removal of residual lint and other impurities.

[0010] Further, the filter structure is arranged opposite to the side wall with the through hole of the shell, and extends to the inner wall of the washing tub where the drain port is arranged. Arranging the filter structure on the side wall with the through hole facilitates the filter structure to be close to the water flow entering from the through hole, that is, to facilitate the filtration of the water flow and the washing of the filter structure by the water flow.

[0011] Further, a guide wall is arranged in the lifting rib for guiding the flow of the drain flow and the washing flow, the guide wall, the side wall of the shell with the through hole, and the inner wall of the washing tub form a filter cavity, the filter cavity covers at least part of the through holes on the side wall, and the filter structure is arranged in the filter cavity. The filter cavity surrounded by the guide wall and the like in the lifting rib guides the washing flow and the drain flow entering the lifting rib, preventing the water flow from being too dispersed to contact the filter structure.

[0012] Further, the drain port is located in the filter cavity, and the guide side wall extends to abut the inner wall of the washing drum; or the drain port is located outside the filter cavity, and a gap is formed between one of the guide side walls close to the drain port and the inner wall of the washing drum, the gap constituting an opening for water flow in the filter cavity to flow to the drain port, and the rest of the guide side walls extend to abut the inner wall of the washing drum. According to the setting position of the drain port, the guide side wall has two setting modes, and the setting of the guide side wall can connect the water entering through the through hole with the drain port.

[0013] Further, the bottom of the filter cavity is provided with a guide plate inclined downward from the guide side wall to the drain port. Through the setting of the guide plate, the water flow can be better guided to the drain port, which is beneficial to the discharge of the impurities such as lint after washing.

[0014] Further, the specific arrangement of the guide plate in the filter cavity is that when the drain port is located in the filter cavity, an inclined guide plate is arranged on each guide side wall to the drain port, and a plurality of guide plates enclose a conical surface with the tip pointing to the drain port; when the drain port is located outside the filter cavity, an inclined guide plate is arranged on the guide side wall away from the drain port to the opening.

[0015] Further, the drain port on the inner wall of the washing drum is located between the two guide side walls, and the two guide side walls extend to abut the inner wall of the washing drum; or the drain port on the inner wall of the washing drum is located outside the two guide side walls, and a gap is formed between one of the guide side walls close to the drain port and the inner wall of the washing drum, the gap constituting an opening for water flow in the filter cavity to flow to the drain port, and the other guide side wall extends to abut the inner wall of the washing drum; the side wall, the inner wall of the washing drum and the two guide side walls enclose the filter cavity, and the filter structure is arranged in the filter cavity. The water flow cleaned by the filter structure in the filter cavity needs to be finally discharged from the drain port, so the two guide side walls also need to be arranged to guide the cleaned water possibly containing impurities such as lint to the position of the drain port. Therefore, according to the position of the drain port, the structure of the two guide side walls is reasonably arranged to ensure that the water flow containing impurities such as lint can be finally discharged from the drain port.

[0016] Further, the bottom of the filter cavity is provided with a guide plate inclined downward from the guide side wall to the drain port; when the drain port is located between the two guide side walls, inclined guide plates are arranged on the two guide side walls to the drain port; when the drain port is located outside the two guide side walls, an inclined guide plate is arranged on the guide side wall away from the drain port to the opening; the side wall, the inner wall of the washing drum, the two guide side walls and the guide plate enclose the filter cavity, and the filter structure is arranged in the filter cavity. The present application also arranges the guide plate in the filter cavity, and through the setting of the guide plate, the water flow is better guided to the drain port for discharge.

[0017] Further, the filtering structure comprises a filtering section for intercepting sundries in the water flow, and the water flow direction at the filtering section position in the filtering cavity forms an included angle with the filtering section; preferably, the water flow direction at the filtering section position in the filtering cavity is perpendicular to the filtering section. The filtering structure is arranged at a position in the filtering cavity, so that the filtering section for intercepting sundries such as line scraps can be washed by the drainage water flow, and then the line scraps and other sundries remaining on the filtering section can be washed away by the water, so as to ensure the cleaning of the filtering structure.

[0018] Further, the filtering section is arranged parallel to the side wall, and the filtering section is projected on the side wall, and the projection covers at least part of the through holes on the side wall; preferably, the projection covers all the through holes on the side wall. The filtering section is arranged parallel to the side wall, so that the water inlet flow in the through holes on the side wall is perpendicular to the filtering section, and then the contact area of the water inlet flow in the through holes with the filtering section is maximized, which facilitates the water flow in the through holes to wash away the line scraps and other sundries at the filtering section position.

[0019] Further, the filtering section is arranged at a position close to the side wall in the filtering cavity. Since the drainage water flow flows into the filtering cavity from the side wall, the water flow at the side wall position is the largest, and the filtering section is arranged at a position close to the side wall, so that the filtering section is washed by the water flow with large flow, and the line scraps and other sundries at the filtering section position are washed away.

[0020] The application also provides a clothes treatment device with the reinforcing rib structure.

[0021] By adopting the above technical scheme, the application has the following beneficial effects compared with the prior art:

[0022] 1) The reinforcing rib structure provided by the application has the through holes for water inlet and the drainage port covered by at least one reinforcing rib, so that the drainage water flow generated by the water flow in the through holes and finally flowing to the drainage port can wash the filtering structure. That is, the reinforcing rib structure provided by the application can wash away the line scraps and other sundries remaining on the internal filtering structure, so as to achieve the self-cleaning of the filtering structure and ensure the filtering effect of the filtering structure without manual operation.

[0023] 2) The lifting rib structure provided by the application is provided with a drainage valve for controlling the opening and closing of the drainage hole and the inner cavity. When the drainage valve controls the drainage hole to be not communicated with the inner cavity, the water flow in and out of the through hole forms a reciprocating washing water flow between the washing cylinder and the inner cavity. The filtering structure is arranged in the path of the washing water flow, so that the filtering structure filters the washing water flow, thereby achieving the effect of filtering the water in the washing cylinder. When the drainage valve controls the drainage hole to be communicated with the inner cavity, a drainage water flow is formed between the communication through hole and the drainage hole. The filtering structure is arranged in the position of the drainage water flow, so that the drainage water flow washes the filtering structure, thereby making the residual line scraps and other impurities on the filtering structure be washed away by the drainage water flow, and the filtering device can realize self-cleaning.

[0024] 3) The position of the filtering structure of the application is reasonable, so that the filtering cross section for intercepting line scraps and other impurities can be washed by the drainage water flow, thereby making the line scraps and other impurities possibly remaining on the filtering cross section be washed away by the drainage water flow, achieving the effect of cleaning the filtering structure. The washing water flow also flows through the filtering cross section, so that the filtering cross section can filter the line scraps and other impurities in the washing water flow.

[0025] 4) In the application, the drainage water flow and the washing water flow are both flowed into the inner cavity from the through hole. The water flow at the position of the through hole has a large flow rate. Therefore, the filtering structure is arranged at the position close to the through hole, so that the filtering structure contacts more washing water flow, thereby filtering more washing water flow. In addition, the filtering structure is arranged on the side wall of the shell provided with the through hole, so that the filtering structure is close to the through hole for water inflow, making it convenient for the filtering structure to wash the inflowing washing water flow and for the filtering structure to be washed by the water flow.

[0026] 5) The application sets a filtering cavity in the lifting rib, which is jointly surrounded by the flow guide side wall, the side wall provided with the through hole and the inner wall of the washing cylinder. The setting of the filtering cavity makes the water flow entering the lifting rib from the through hole not too divergent, so that the inflowing water flow is mainly concentrated in the filtering cavity. The filtering structure is arranged in the filtering cavity, so that the filtering structure contacts the washing water flow and the drainage water flow.

[0027] 6) The drainage water flow after washing the filtering structure has line scraps and other impurities, which will affect the flow of the drainage water flow. The application sets an inclined flow guide plate at the bottom of the filtering cavity, so that the flow guide plate can better guide the flow of the drainage water flow, thereby facilitating the discharge of the sewage with line scraps and other impurities. In combination with the position of the drainage port, the setting of the flow guide plate is reasonable, so that the drainage water flow is more easily flowed out of the drainage port along the inclined taper surface.

[0041] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the embodiments will be described in detail below with reference to the drawings of the embodiments of the present application.

[0042] Embodiment 1

[0043] The lifting ribs provided on the inner wall of the washing drum for lifting water flow have been patented, and the water in the washing drum can be introduced into the lifting ribs, and the filtering structure provided in the lifting ribs can filter the water in the washing drum. However, the filtering structure provided in the lifting ribs 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 cause the filtering structure provided in the lifting ribs to be covered with a large amount of lint and other impurities after long-term use, which will affect the filtering effect of the filtering structure. The filtering structure in the lifting ribs cannot be cleaned automatically, and the filtering 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 filtering structure 5 in the lifting rib 16 can be cleaned automatically, and the filtering structure 5 can be kept clean and the filtering effect can be ensured without manually cleaning the filtering structure 5.

[0044] The lifting rib 16 provided in the embodiment includes an outer shell 1 provided on the inner wall 3 of the washing drum, the outer shell 1 constitutes the outer contour of the lifting rib 16, and the inner cavity 4 is formed between the outer shell 1 and the inner wall 3 of the washing drum, and the inner cavity 4 is the internal space of the lifting rib 16. The through hole 2 provided on the outer shell 1 is used for water to flow in and out, 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 filtering 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 filtering structure 5. A plurality of drain holes 6 for draining water in the washing drum are provided on the inner wall 3 of the washing drum, and the inner cavity 4 covers at least one drain hole 6. Such a configuration allows water to flow into the inner cavity 4 of the lifting rib 16 through the through hole 2, and then the water flowing into the inner cavity 4 of the washing drum is drained through the drain hole 6. That is, the water draining flow in the washing drum includes a water draining path from the through hole 2 to the drain hole 6, and since the inner cavity 4 covers at least one drain hole 6, the inner cavity 4 at least includes one of the above-mentioned water draining paths, and the filtering structure 5 is provided in the inner cavity 4, so that the water draining path can pass through the filtering structure 5 in the inner cavity 4. In this way, the filtering structure 5 can be washed by the water draining flow according to the water draining path, so as to wash away the lint and other impurities remaining on the filtering structure 5 by the water draining flow, and achieve the effect of cleaning the filtering structure 5.

[0045] 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 out of the wall of the washing drum.

[0046] 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.

[0047] More preferably, the filtering section 12 is arranged parallel to the side wall 8 on which the through holes 2 are arranged. Since the through holes 2 are arranged on the side wall 8 for water to flow in, the filtering section 12 is arranged parallel to the side wall 8 so that the water flow from the through holes 2 on the side wall 8 is perpendicular to the filtering section 12. And no matter whether it is the flushing water flow or the drainage water flow, the water flow enters the inner cavity 4 from 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 can more easily flush the filtering section 12, and the flushing water flow entering the inner cavity 4 can be filtered. The filtering section 12 projects towards 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 from 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 from 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.

[0048] 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 to flow in 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 to flow in. The water flow entering the inner cavity 4 is certainly greater the closer it is to the water inlet, so arranging the filtering section 12 close to the through holes 2 for water to flow in 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, so 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 sides of the lifting ribs 16, and the filtering structure 5 is arranged close to the through holes 2.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Since the drainage water in the filter chamber 7 ultimately needs to flow to the drain outlet 6 for discharge, a guide plate 11 can be installed in the filter chamber 7 to guide the water flow to the drain outlet 6. The guide plate 11 makes it easier for the water flow in the filter chamber 7 to converge at the drain outlet 6, resulting in a larger flow of water towards the drain outlet 6. Even after cleaning the filter structure 5, the water containing debris such as lint can flow to the drain outlet 6 and be discharged under the guidance of the guide plate 11. Because the water flow after cleaning the filter structure 5 contains debris such as lint that obstructs the water flow, the guide plate 11 further concentrates the water flow, resulting in a larger flow of water towards the drain outlet 6, making it easier for debris such as lint to be discharged from the drain outlet 6.

[0054] Specifically, such as Figure 2 , 4 As shown, the bottom of the filter chamber 7 is provided with a guide plate 11 that slopes downwards from the guide sidewall 9 towards the drain outlet 6. The inclined structure of the guide plate 11 facilitates the flow of drainage water along the inclined guide plate 11 towards the drain outlet 6, and the inclined structure of the guide plate 11 increases the flow velocity of the drainage water, making it easier to flush away debris such as lint in the drainage water. Since the drain outlet 6 has two possible configurations: it can be located between the guide sidewalls 9 or outside the guide sidewalls 9, the guide plate 11 that guides the water flow to the drain outlet 6 also has two configurations. When the drain outlet 6 is located between the guide sidewalls 9, guide plates 11 that slope towards the drain outlet 6 are respectively provided on the guide sidewalls 9. All guide plates 11 form a conical surface with the tip pointing towards the drain outlet 6.

[0055] The conical surface formed by the inclined guide plate 11 gradually reduces the cross-sectional area flowing towards the drain outlet 6, thus accelerating the flow velocity of the water towards the drain outlet 6 and making it easier for water containing lint to be discharged from the drain outlet 6. When the drain outlet 6 is located outside the guide sidewall 9, as mentioned above, this situation requires an opening 10 to be set on the guide sidewall near the drain outlet 6. This necessitates guiding the drainage water flow in the filter chamber 7 towards the side where the opening 10 is located, i.e., the drainage water flow needs to be deflected towards the guide sidewall where the opening 10 is located. Therefore, a guide plate 11 inclined towards the opening 10 is set on the guide sidewall away from the drain outlet 6, above the opening 10. The guide plate 11 guides the drainage water flow towards the drain outlet 6 and discharges it. After the guide plate 11 is set, the sidewall 8, the inner wall 3 of the washing drum, the two guide sidewalls 9, and the guide plate 11 together form the filter chamber 7, and the filter structure is set inside the filter chamber 7. The design of the filter chamber 7 allows for better guidance of the drainage water flow, thereby enabling the filter structure 5 within the filter chamber 7 to be effectively flushed by the drainage water flow.

[0056] 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 wash away 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 manually cleaned, and the self-cleaning of the filtering structure 5 can be realized by using the drainage in the washing drum.

[0057] Embodiment 2

[0058] On the basis of the above-mentioned embodiment, the present embodiment provides a non-porous washing machine. 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 using 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. By using the drainage valve 15, the drainage port 6 can be connected with 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 process of the non-porous washing machine, the drainage water flow which can wash the filtering structure 5 is 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 make the filtering structure 5 in the lifting rib 16 self-cleaned, so as to ensure the filtering effect.

[0059] Embodiment 3

[0060] The washing machine is provided with a washing drum for containing washing water, washing clothes, and draining the washing water. The lifting rib for lifting water flow is usually arranged on the inner wall 3 of the washing drum. The lifting rib includes 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 shape of the outer shell 1 to achieve the effect of lifting water flow, and the inner cavity 4 is a hollow cavity. Therefore, in order to save space, the components required in the washing machine can be arranged in the hollow cavity of the inner cavity 4. At present, there is a patent which uses the space of the inner cavity 4 to arrange a filtering structure, and a through hole 2 for water inletting and outletting is arranged on any side wall 8 of the outer shell 1, so that the water flow in the washing drum can flow into the inner cavity 4 through the through hole 2, and then 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.

[0061] 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.

[0062] 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.

[0063] 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 the water flow is obviously the most concentrated and largest at the position of flowing into the lifting rib. 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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 in through 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.

[0068] 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.

[0069] 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.

[0070] Embodiment 4

[0071] 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. Figure 6 As 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.

[0072] As 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. Figure 6As shown, the filter rods 20 are inclinedly arranged on the cylindrical rods 19, with each filter rod 20 extending gradually outward from the bottom to the top along the axial direction of the cylindrical rod 19. The inclined arrangement of the filter rods 20, compared to a horizontal arrangement, makes it easier for impurities such as lint to be suspended on the filter rods 20 and for them to be more easily trapped between the filter rods 20 and the cylindrical rod 19. Since the top of the comb teeth 17 is fixed to the side wall of the outer casing 1, and as can be seen from the aforementioned extension direction of the comb teeth 17, the bottom of the comb teeth 17 is closer to the inner wall 3 of the washing drum. Since water flow inside the lifting ribs often needs to flow from the outer casing 1 to the inner wall 3 of the washing drum, the filter rods 20 extend gradually outward from the bottom to the top, allowing lint and other debris in the water flow to be more easily intercepted by the filter rods 20, thus achieving a better filtration effect. In other words, the filter rods 20 gradually contract along the direction of the incoming water flow, making it easier for lint and other debris to be trapped or suspended on the filter rods 20. Figure 4 As shown, multiple comb teeth 17 are provided on different sides of the cylindrical rod 19, and multiple filter rods 20 on each side are arranged sequentially along the axial direction on the cylindrical rod 19. Providing multiple comb teeth 17 on different sides of the cylindrical rod 19 increases the unfolded area of ​​the cylindrical rod 19, making it easier to intercept impurities such as lint. Arranging multiple filter rods 20 sequentially along the axial direction on the same side saves space, reduces the volume occupied by the comb teeth 17, and minimizes the mutual interference between adjacent comb teeth 17.

[0073] As shown in Example 1, the cylindrical rod 19 is fixed to the side wall 8 where the through hole 2 is located, so that the cylindrical rod 19 can only be staggered with the through hole 2. In reality, water flows in through the through hole 2. Therefore, to filter the water flow, the filter rod 20 should extend towards the through hole 2 so that the water flowing in through the through hole 2 can directly contact the filter rod 20, thereby filtering the water flow through the filter rod 20. That is, the cylindrical rod 19 cannot be directly set at the through hole 2 in the side wall 8, but because the filter rod 20 on the cylindrical rod 19 extends outward from the cylindrical rod 19, the filter rod 20 can be directly facing the through hole 2, thereby increasing the contact area between the water flow and the filter rod 20, and thus improving the filtering effect of the filter rod 20. Specifically, as follows... Figure 4 As shown, the filter rod 20 extends outward from the cylindrical rod 19 to the through hole 2 closest to the side where the filter rod 20 is located, and the filter rod 20 projects onto the side wall 8 where the through hole 2 is located, the projection covering a portion of the area of ​​the through hole 2. This arrangement ensures that a portion of the area of ​​the filter rod 20 is opposite to that of the through hole 2, allowing the water flowing into the through hole 2 to contact the filter rod 20 and be filtered by it.

[0074] like Figure 6As 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.

[0075] 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 and the adjacent comb tooth 17 have no gap, that is, there is a position of abutment, the water flow at the position of abutment 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 is subjected to the filtering treatment of the comb tooth 17, improving the filtering effect.

[0076] Embodiment 5

[0077] 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 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 water filling, washing, spinning and drainage can be realized.

[0078] 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.

[0079] 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.

[0080] As shown in Figure 7 , 3 The drainage valve 15 is arranged at the drainage port 6 to control the water flow of the drainage port 6. The drainage valve 15 includes a liftable valve core, and the valve core can correspondingly 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] As shown in Figure 7 、 8 , the installation cavity bottom wall 25 is provided with a limiting groove 27 limiting the falling limit position of the counterweight structure 23, and the counterweight structure 23 falling to the limit position is embedded in the limiting groove 27. The counterweight structure 23 can be lifted and lowered, and the counterweight structure 23 will fall 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 limited to move to the position of the drainage port 6, thereby achieving good blocking of the drainage port 6.

[0086] 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.

[0087] 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 the figure, 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 and the inner wall 3 of the washing drum have a water inlet gap 37, 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.

[0088] As shown in the figure, 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.

[0089] 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.

[0090] 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.

[0091] 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 in the mounting hole 33 arranged on the inner wall 3 of the washing drum, and the positioning column 34 corresponding to the mounting hole 33 is inserted into the mounting hole 33. In this way, 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.

[0092] The lifting rib 16 provided by the present application comprises the drainage space 35 and the filter space 21 which are independent of each other, so that the filter space 21 of the lifting rib 16 can filter water in the washing drum, and the drainage space 35 of the lifting rib 16 can drain water in the washing drum. Due to the reasonable arrangement of the filter space 21 and the drainage space 35, they do not affect each other.

[0093] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content with the above-mentioned prompt as equivalent embodiments with equivalent changes without departing from the technical solution of the present application. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical solution of the present application still belongs to the scope of the present application.
