[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] like Figures 1-9 As shown, this utility model discloses a water-repellent rib assembly with a detachable filter screen assembly, comprising:

[0043] The water-dispelling rib body 1 is fixedly installed on the inner side wall of the washing tub of the washing machine. The water-dispelling rib body 1 forms a hollow trough-shaped structure. A water-dispelling rib passage 2 is provided on one side of the water-dispelling rib body 1, so that water in the washing tub can enter the trough-shaped structure through the water-dispelling rib passage 2.

[0044] A filter assembly 3 is detachably disposed in the trough structure for filtering water entering the trough structure;

[0045] The drainage component is installed on the water-repellent rib body 1 and is used to discharge the water filtered by the filter screen component 3 out of the washing tub when the washing machine is in the draining or spin-drying state.

[0046] Through the above setting, the water dispersing rib body 1 and the filter screen assembly 3 and the drainage assembly are matched to form an integrated structure, which on the one hand reduces the number of parts dispersedly arranged in the washing tub, saves the washing space, improves the assembly efficiency, and on the other hand can comprehensively filter the water discharged from the washing tub, thereby effectively removing the cloth scraps therein and avoiding the risk of clogging of the drainage pipeline. In addition, when the filter screen assembly 3 needs to be cleaned, the filter screen assembly 3 can be separately detached from the water dispersing rib body 1 for cleaning, which is simple and convenient to operate. Through the above setting, the place in the washing tub except the water dispersing rib can also be set as a non-porous structure to form a non-porous inner tub, and the drainage assembly is in a closed state in the washing tub static state or the washing state, so as to isolate the inner tub and the outer tub from each other in the washing process, prevent the dirt in the outer tub from entering the inner tub, and cause secondary pollution to the clothes. In the drainage state or the dehydration state, the water in the washing tub can be completely drained through the drainage assembly. It should be noted that the water dispersing rib assembly provided in the example is fixedly arranged on the inner side wall of the washing tub and is more than one in number. The fixing mode can adopt any one of the following implementation modes, such as bolt connection, concave-convex cooperation, clamping, and fixing by a third connecting piece, and is not limited herein.

[0047] Specifically in the example, as Figure 8As shown, the filter screen assembly 3 comprises a filter screen base 35 and a filter screen substrate 36, the filter screen base 35 and the filter screen substrate 36 cooperate to form a filter box body, one end of the filter screen base 35 is rotatably connected with the filter screen substrate 36 through a filter screen shaft 33, for rotating to open or close the filter box body, a water inlet structure is arranged on one side of the filter box body, the water inlet structure is arranged corresponding to the water passing channel 2 of the water pushing rib body 1, and filter screen mesh parts 38 are arranged on at least two surfaces of the filter box body close to and away from the bottom of the water pushing rib body 1 respectively, when the washing machine is in a drainage working condition or a dehydration working condition, the water filtered through the filter screen mesh parts 38 can be discharged out of the washing tub through the drainage assembly. It should be noted that the bottom of the water pushing rib body 1 refers to the surface of the water pushing rib body 1 close to the inner side wall of the washing tub. Through the above arrangement, the water passing through the water passing channel 2 of the water pushing rib can smoothly enter the filter box body, and then the cloth scraps in the washing water can be filtered by the filter screen mesh part 38 away from the bottom of the water pushing rib body 1 during the washing working condition, and the cloth scraps can be collected in the filter box body, and the water discharged from the washing tub during the dehydration working condition and the drainage working condition needs to pass through the filter screen mesh part 38 close to the bottom of the water pushing rib body 1 before being discharged, so that the cloth scraps in the water can be effectively prevented from entering the drainage pipeline, in addition, during the dehydration working condition and the drainage working condition, the filter screen mesh part 38 away from the bottom of the water pushing rib body 1 can also be used as the water inlet of the filter box body, so as to improve the drainage efficiency. Preferably, the filter screen base 35 and the filter screen substrate 36 are provided with filter screen mesh parts 38 on all surfaces except the surface provided with the water inlet structure, which can further improve the filtering effect and filtering efficiency of the filter screen assembly 3.

[0048] Optionally, a shielding part is arranged at the water inlet structure of the filter screen assembly 3, which can open the water inlet structure under the action of centrifugal force when the washing tub rotates along a first direction, and can block the water inlet structure under the action of centrifugal force when the washing tub rotates along a second direction, the first direction being the rotating direction of the washing tub during dehydration or drainage, and the second direction being opposite to the first direction. Preferably, the shielding part is a flexible part made of flexible materials such as rubber, one side of the shielding part is fixedly connected with the filter screen assembly 3, and the other three sides are movable sides. When the washing tub rotates along the first direction, the shielding part is bent and deformed towards the inside of the filter box body under the action of centrifugal force, so that the water inlet structure is opened and the water during washing can be filtered. When the washing tub rotates along the second direction, the shielding part returns to the shielding state and is arranged in abutment with the inner wall of the filter screen assembly 3, so as to block the water inlet structure, avoid the collected lint in the filter box body from flowing into the washing water again, and ensure the collection and filtering effect of the filter screen assembly 3 on the lint. As another optional example, the shielding part can also be made of hard materials such as plastic, and one side of the shielding part is rotatably connected with the filter screen assembly 3. When the washing tub rotates along the first direction, the shielding part rotates towards the inside of the filter box body under the action of centrifugal force, so that the water inlet structure is opened and the water during washing can be filtered. When the washing tub rotates along the second direction, the shielding part rotates towards the water inlet structure and abuts against the inner wall of the filter screen assembly 3, so as to block the water inlet structure, avoid the collected lint in the filter box body from flowing into the washing water again, and ensure the collection and filtering effect of the filter screen assembly 3 on the lint. It should be noted that the water passing channel 2 and the water inlet structure are arranged on one side of the lint removing rib body 1, and the side faces the forward direction when the washing tub rotates along the first direction.

[0049] As an example of the present application, as shown in Figure 8 The water inlet structure includes a water passing groove 34 and a filter screen substrate water inlet 37, the water passing groove 34 is arranged on one side of the filter screen base 35, the filter screen substrate water inlet 37 is arranged on the filter screen substrate 36, and the water passing groove 34 and the filter screen substrate water inlet 37 are correspondingly arranged. The arrangement of the water passing groove 34 and the filter screen substrate water inlet 37 can significantly improve the water inlet efficiency in the filter box body, and further improve the filtering effect and drainage efficiency of the filter screen assembly 3.

Optionally, a screw table is arranged in the second space, and the top cover 4 is fixedly connected with the screw table by a screw to be arranged on the second space. The communication between the first space and the second space means that the water filtered by the filter screen assembly 3 in the first space can enter the second space.

Optionally, a screw table is arranged in the second space, and the top cover 4 is fixedly connected with the screw table by a screw to be arranged on the second space. The communication between the first space and the second space means that the water filtered by the filter screen assembly 3 in the first space can enter the second space.

[0052] Specifically, an elastic locking structure is arranged between the first end of the filter screen assembly 3 and the drain rib body 1, the elastic locking structure can be locked in cooperation when the filter screen assembly 3 is installed, and a limiting structure is arranged between the second end of the filter screen assembly 3 and the top cover 4, the limiting structure is used for limiting the second end of the filter screen assembly 3. Through the cooperation of the elastic locking structure and the limiting structure, the filter screen assembly 3 can be detachably arranged on the drain rib body 1. Specifically, when installed, the second end of the filter screen assembly 3 is limited in cooperation with the top cover 4, and then the first end is pressed towards the drain rib body 1, which is simple and convenient.

[0053] As one of the optional examples, the elastic locking structure comprises a hook structure 31 and a lock structure 11, the hook structure 31 and the lock structure 11 can be locked in cooperation and can be elastically deformed to be unlocked under the action of an external force. The hook structure 31 is arranged on the filter screen assembly 3 or the drain rib body 1, and the lock structure 11 is correspondingly arranged on the drain rib body 1 or the filter screen assembly 3. It should be noted that the hook structure 31 can be an elastic buckle as shown in Figure 2 、 Figure 7 The hook structure 31 can be an elastic buckle as shown in

[0054] As an example of the utility model, the limiting structure includes filter screen buckle part 32 and reverse buckle structure 41, the filter screen buckle part 32 is set on filter screen assembly 3, and is protruded to top cover 4 direction, the reverse buckle structure 41 is set on top cover 4, and is protruded to filter screen assembly 3 direction, when filter screen assembly 3 is installed, the filter screen buckle part 32 is attached the inner side of reverse buckle structure 41 and forms limit.The inner side of reverse buckle structure 41 refers to its one side towards groove structure space. Optionally, the reverse buckle structure 41 forms an angle with the support plate, and / or, an angle is formed between filter screen buckle part 32 and the wall surface where it is located, in this case, when filter screen buckle part 32 is attached to the inner side of reverse buckle structure 41, the end of reverse buckle structure 41 abuts against the wall surface where filter screen buckle part 32 is located, and / or, filter screen buckle part 32 abuts against the support plate, in the case that top cover 4 and support plate have been fixed, the second end of filter screen assembly 3 is also limited.

[0055] As one of the optional examples, the drainage assembly includes a drainage through hole and a centrifugal valve group, the drainage through hole is arranged at the bottom of the water-repellent rib body 1, a drainage port is arranged on the washing barrel, the drainage through hole is arranged corresponding to the drainage port to cooperate to form a drainage passage, the centrifugal valve group is arranged on the drainage through hole, the centrifugal valve group can block the drainage passage when the washing barrel is static or rotates at low speed, and can open the drainage passage under the action of centrifugal force when the washing barrel rotates at high speed.

[0056] By the above arrangement, the washing tub can be arranged as a non-porous inner tub, which is a non-porous structure at positions other than the drain port. By arranging the centrifugal valve group, the drain passage is blocked when the non-porous inner tub is stationary or rotates at a low speed, avoiding the outflow of washing water and ensuring the normal operation of the washing condition. At the same time, it can effectively prevent washing water from entering between the outer tub and the inner tub, avoid secondary pollution caused by the exchange of washing water between the inner and outer tubs during the washing process, and ensure the washing effect of the clothes. When the non-porous inner tub rotates at a high speed, it is usually in a draining or dewatering condition. At this time, the centrifugal valve group is connected under the action of centrifugal force or inertial force, thereby connecting the drain passage and draining the washing water in the non-porous inner tub outside the tub, realizing the smooth drainage of the non-porous inner tub. It should be noted that low-speed rotation refers to the rotational speed of the non-porous inner tub in the washing condition, which is usually below 150 r / min, and high-speed rotation refers to the rotational speed of the non-porous inner tub in the draining or dewatering condition, which is usually above 150 r / min. It should be noted that the low-speed rotation and high-speed rotation in the present application can be set by a preset rotational speed. When the rotational speed of the non-porous inner tub is below a first preset rotational speed, it is low-speed rotation, and the washing machine is in a water inlet condition, a washing condition, or a rinsing condition. When the rotational speed is above a second preset rotational speed, it is high-speed rotation, and the washing machine is in a dewatering condition or a draining condition. The first preset rotational speed is less than the second preset rotational speed, and preferably, the first preset rotational speed is between 100 and 150 r / min, and the second preset rotational speed is between 150 and 200 r / min. The specific value can be determined according to the specifications and models of the washing machine, which will not be limited here. In addition, a third preset rotational speed can also be set according to the requirements, which is greater than the second preset rotational speed, and the third preset rotational speed is between 200 and 300 r / min. When the rotational speed of the washing tub reaches the third preset rotational speed or above, the centrifugal valve group is completely opened, facilitating the smooth progress of the dewatering or draining process. In one example, when the washing tub is not rotating or the rotational speed of the washing tub is below 100 r / min, the centrifugal valve group is in a closed state. When the washing tub needs to be dewatered or drained, the rotational speed reaches 150 r / min or above, the centrifugal valve group gradually opens, and the drain passage gradually connects. When the rotational speed reaches 200 r / min or above, the centrifugal valve group is completely opened, realizing the drainage or dewatering of the washing tub. In this example, the first preset rotational speed is 100 r / min, the second preset rotational speed is 150 r / min, and the third preset rotational speed is 200 r / min. It should be noted that the centrifugal valve group includes a centrifugal valve 7 and / or a duckbill check valve 5.

[0057] As one of the optional examples, Figures 2-6As shown, the centrifugal valve group comprises a duckbill check valve 5, the drain through hole comprises a second drain hole arranged at the bottom of the drain rib body 1 corresponding to the first space, and the duckbill check valve 5 is arranged at the second drain hole and can be opened to guide the second drain hole and the drain port in communication when the washing tub rotates at high speed. Through the above arrangement, when the washing tub rotates at low speed, the duckbill check valve 5 is in a closed state, which can prevent water in the washing tub from entering between the outer tub and the inner tub, and when rotating at high speed, the duckbill check valve 5 is opened to guide the second drain hole and the drain port in communication, facilitating the water in the washing tub to be discharged. It should be noted that the opening pressure of the duckbill check valve 5 opened or closed under different rotating speeds according to different models and specifications can be adjusted by adjusting one or more parameters of the raw rubber material of the duckbill check valve 5, such as the material, hardness, length and width of the duckbill, and the thickness of the duckbill valve tongue. The specific adjustment method can refer to the prior art, which is not limited here.

[0058] As one of the examples, as Figure 9 As shown, the duckbill check valve 5 comprises a mounting portion 501 and first and second valve tongues 502 and 503, the mounting portion 501 is fixedly installed on the circumference of the second drain hole, and the first and second valve tongues 502 and 503 are in sealing abutment in a normal state. Under the high-speed rotating state of the washing tub, the first and second valve tongues 502 and 503 are away from each other under the action of centrifugal force and water pressure, so that the second drain hole and the drain port are in communication. Among them, the normal state refers to the state of the washing tub at rest or low speed rotation. It should be noted that when the washing tub rotates at low speed, the centrifugal force and water pressure borne by the first and second valve tongues 502 and 503 are not enough to separate the two, so that they can be kept in a sealed state to prevent water in the washing tub from flowing out, and when the washing tub rotates at high speed, the first and second valve tongues 502 and 503 gradually move away from each other, thereby being able to discharge the water in the washing tub.

[0059] As another optional example, as Figure 2As shown, the centrifugal valve group comprises a centrifugal valve 7 arranged in the second space, the drain through hole comprises a first drain hole arranged at the bottom of the lint body 1 corresponding to the second space, the centrifugal valve 7 is arranged in cooperation with the first drain hole, and the centrifugal valve 7 can guide the first drain hole to be communicated with the drain port when the washing tub rotates at a high speed. It should be understood that the distance between the inner tub and the outer tub in the washing machine is small, the valve tongue of the duckbill check valve 5 is relatively long, and is easy to contact or interfere with the outer tub, thereby affecting the plugging effect and the drainage effect. In order to avoid the contact or interference between the duckbill check valve 5 and the outer tub, the duckbill check valve 5 is moved in the direction of the center of the inner tub in the specific arrangement, and the side of the duckbill check valve 5 close to the inner tub is arranged protruding relative to the bottom of the lint body 1. In this case, if the duckbill check valve 5 is arranged alone, a part of water cannot be drained out of the tub, thereby affecting the drainage effect of the inner tub. Therefore, the corresponding centrifugal valve 7 needs to be arranged in cooperation to ensure that the water in the inner tub is drained, so as to improve the user experience. In addition, if the centrifugal valve 7 is arranged alone, the space occupied by the structure similar to the seesaw is large, and the corresponding filter structure cannot be arranged, so that the lint in the water cannot be removed, thereby affecting the user experience. Since the duckbill check valve 5 occupies a small space, the filter structure can be conveniently arranged at the position of the duckbill check valve 5. Therefore, the duckbill check valve 5 and the centrifugal valve 7 are arranged on the lint at the same time, which can ensure that the water in the inner tub is drained, and the filter screen can be arranged to filter the lint in the water, thereby significantly improving the user experience.

[0060] As one of the preferred examples, one or more first drain holes are arranged at the bottom of the lint body 1, and / or one or more second drain holes are arranged at the bottom of the lint body 1, the number of the centrifugal valves 7 is arranged corresponding to the number of the first drain holes, and the number of the duckbill check valves 5 is arranged corresponding to the number of the second drain holes. Through the above arrangement, the number of the first drain holes, the centrifugal valves 7, the second drain holes and the duckbill check valves 5 can be arranged according to the specific model and specifications of the washing machine, so as to ensure the drainage efficiency of the washing machine.

[0061] As an example of the present application, the diameter of the first drain hole is larger than the diameter of the second drain hole. Through the above arrangement, the drainage capacity of the first drain hole can be significantly improved, so as to quickly drain the water in the non-porous inner tub and improve the drainage efficiency.

[0062] As one of the examples, as shown in FIG. 1, the first drain hole is arranged at the bottom of the lint body 1 corresponding to the second space, and the second drain hole is arranged at the bottom of the lint body 1 corresponding to the first space. Figure 2As shown, the centrifugal valve 7 includes a counterweight part 701, a rotating shaft part 702, a torsion spring 703, and a sealing part 704. The centrifugal valve 7 is locked or rotated relative to the bottom of the water deflector body 1 through the rotating shaft part 702 and the torsion spring 703. The counterweight part 701 and the sealing part 704 are respectively arranged on opposite sides of the rotating shaft part 702. When the washing tub is static or rotates at a low speed, the sealing part 704 is in sealing contact with the first drain hole under the action of the torsion spring 703. When the washing tub rotates at a high speed, the counterweight part 701 of the centrifugal valve 7 rotates against the action of the torsion spring 703 under the action of centrifugal force, and then separates the sealing part 704 from the first drain hole. It should be noted that, through the above structure, the centrifugal valve 7 forms a structure similar to a seesaw around the rotating shaft part 702. When the washing tub is static or rotates at a low speed, the pre-tightening force of the torsion spring 703 applied to the counterweight part 701 keeps it away from the bottom of the water deflector body 1. Correspondingly, the sealing part 704 keeps close to the bottom of the water deflector body 1, so as to block the first drain hole. When the washing tub rotates at a high speed, the counterweight part 701 moves towards the bottom of the water deflector body 1 against the pre-tightening force of the torsion spring 703 under the action of centrifugal force or inertial force. At this time, the sealing part 704 moves away from the bottom of the water deflector body 1 around the rotating shaft part 702, so as to separate the sealing part 704 from the first drain hole, thereby facilitating the water in the washing tub to be drained. It should be noted that, in order to ensure that the auxiliary counterweight part 701 overcomes the action of the torsion spring 703 under the action of centrifugal force, a counterweight block (not shown in the figure) is arranged on the counterweight part 701. It should be noted that the length of the counterweight part 701 and the sealing part 704, the mass of the counterweight block, and the related parameters of the torsion spring 703 can be obtained by calculation. The related calculation method belongs to the prior art and will not be limited herein.

[0063] As one of the preferred examples, as shown in Figure 2 、 Figure 5 As shown, a rubber sealing ring 6 is sleeved on the circumference of the first drain hole. When the washing tub is static or rotates at a low speed, the sealing part 704 cooperates with the rubber sealing ring 6 to form a seal. Specifically, when the washing tub is static or rotates at a low speed, the sealing part 704 of the centrifugal valve 7 cooperates with the rubber sealing ring 6 to form a seal under the action of the torsion spring 703, thereby blocking the first drain hole, which can effectively prevent washing water from entering between the outer tub and the inner tub. When the washing tub rotates at a high speed, the counterweight part 701 of the centrifugal valve 7 moves towards the bottom of the water deflector body 1 against the action of the torsion spring 703 under the action of centrifugal force or inertial force, thereby driving the sealing part 704 to move away from the bottom of the water deflector body 1. Then, the sealing part 704 is separated from the rubber sealing ring 6, so that the first drain hole is communicated with the drain port, thereby draining the water in the washing tub.

[0064] As one of the preferred examples, as shown in Figure 1 、 Figure 7 The top cover 4 is provided as a filter structure. A plurality of through holes for filtering are provided on the top cover 4. Through the above arrangement, when draining, part of the water can be filtered through the top cover 4 and then drained from the second space, which can ensure that all the drained water is filtered and can improve the drainage efficiency.

[0065] The duckbill check valve 5 and the centrifugal valve 7 in the water pushing rib described in the present application are opened when rotating at high speed in the dehydration and drainage working condition of the washing tub, and are kept closed in the non-dehydration and non-drainage working condition, thereby ensuring the normal operation of each working condition in the clothes washing process.

[0066] As one of the preferred examples, one or more first drainage holes are provided on the water pushing rib body 1, and / or one or more second drainage holes are provided on the water pushing rib body 1, the number of the centrifugal valves 7 is correspondingly arranged according to the number of the first drainage holes, and the number of the duckbill check valves 5 is correspondingly arranged according to the number of the second drainage holes. Through the arrangement, the number of the first drainage holes, the centrifugal valves 7, the second drainage holes, and the duckbill valves can be set according to the specific model and specifications of the washing machine, so as to ensure the drainage efficiency of the washing machine.

[0067] Specifically, the working principle of the water pushing rib assembly is as follows:

[0068] When the washing tub is not rotating or the rotating speed is lower than the first preset rotating speed (100 r / min, i.e. the washing state), the duckbill check valve 5 and the centrifugal valve 7 are in the closed state, and the first drain hole and the second drain hole are blocked, respectively. At this time, the water entering the water deflector will not be discharged out of the tub, nor will it enter between the inner tub and the outer tub, but will only circulate in the washing tub, thereby avoiding secondary pollution of the laundry. When it is necessary to drain or spin, the rotating speed of the washing tub is increased, and when it is increased to above the second preset rotating speed (150 r / min), the duckbill check valve 5 and the centrifugal valve 7 are gradually opened, and the first drain hole and the second drain hole are respectively communicated with the drain port. The water in the washing tub is gradually discharged outward. When the rotating speed of the washing tub reaches above the third preset rotating speed (200 r / min), the duckbill check valve 5 and the centrifugal valve 7 are completely opened, and the water can be discharged at the maximum speed. The washing tub is a non-porous inner tub, and all the water needs to be discharged through the duckbill check valve 5 and the centrifugal valve 7. In this case, the discharged water needs to pass through the filter of the filter assembly 3 before being discharged, which can effectively filter the lint in the water. Preferably, during the draining process, the rotating speed of the washing tub is lower than the third preset rotating speed, and when most of the water in the washing tub is discharged (which can be determined according to the water level or other means, and is not limited herein), the rotating speed of the washing tub is increased for high-speed spinning. This setting can avoid high-speed spinning of the washing tub under heavy load, thereby preventing mechanical damage.

[0069] When it is necessary to clean the filter assembly 3, the hook structure 31 is pressed by hand to unlock the elastic locking structure, and the filter assembly 3 is rotated outward, so that the filter screen fastening part 32 at the other end of the filter assembly 3 is separated from the reverse fastening structure 41, thereby separating the filter assembly 3 from the groove-shaped structure. Then, the filter screen base 35 and the filter screen substrate 36 are rotated by a certain angle around the filter screen rotating shaft 33 to open the filter box (as shown in Figure 8 After cleaning, the filter assembly 3 can be installed back into the groove-shaped structure by reversing the above operation, which is simple and convenient to disassemble and assemble.
