Detailed Embodiments

[0071] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

This is only for convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0073] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected to", "communicated with" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0074] First, refer to Figure 1 , as Figure 1 shown, the agitator of the present invention includes an agitator disk 1 and a first flexible part 2 provided on the agitator disk 1. The first flexible part 2 covers at least a partial area of the agitator disk 1. The first flexible part 2 includes a first embedding member 221, and the first embedding member 221 is embedded in the agitator disk 1. The embedding direction of the first embedding member 221 is perpendicular to the shedding direction (upward shedding) of the first flexible part 2. By embedding the first embedding member 221 in the agitator disk 1, the shedding of the first flexible part 2 can be avoided. The first flexible part 2 can cover a partial area of the agitator disk 1 or the entire area of the agitator disk 1, and those skilled in the art can set it according to the actual situation.

[0075] Further, in this preferred embodiment, the first flexible portion 2 covers the upper surface of the impeller disk 1 and the peripheral side of the impeller disk 1, and a plurality of embedding grooves 12 are provided on the peripheral side of the impeller disk 1, and a plurality of first embedding members 221 are respectively located in the plurality of embedding grooves 12. Specifically, the first flexible portion 2 includes a surface disk 21 and a peripheral side portion 22, the peripheral side portion 22 surrounds the surface disk 21, and the peripheral side portion 22 extends downward, the surface disk 21 can completely cover the upper surface of the impeller disk 1, the peripheral side portion 22 can surround and cover the peripheral side of the impeller disk 1, the peripheral side portion 22 is connected to the first embedding member 221, the first embedding member 221 is horizontally embedded in the embedding groove 12, the falling direction of the first flexible portion 2 is vertically upward, or the first flexible portion 2 is easy to be lifted upward, fall off with the passage of time and cause wear to the clothes, and the horizontal embedding of the first embedding member 221 can prevent the first flexible portion 2 from falling off.

[0076] In addition, in the present preferred embodiment, there are multiple first embedded components 221, and the multiple first embedded components 221 are circumferentially arranged and evenly distributed. Correspondingly, the number of embedded grooves 12 is the same as the number of first embedded components 221. The embedded grooves 12 extend downwardly through the bottom of the impeller disc 1, so that a wear-resistant portion 13 is formed between every two adjacent embedded grooves 12. The wear-resistant portion 13 is a protrusion extending downward from the impeller disc 1, that is, there is one embedded groove 12 between two wear-resistant portions 13. The lower surface of the first embedded component 221 is higher than the lower surface of the wear-resistant portion 13. When the impeller rotates, if an offset occurs, the wear-resistant portion 13 is rubbed first, thereby preventing the first flexible portion 2 from being worn.

[0077] It should be noted that the present invention does not impose any limitation on the specific structure of the embedding groove 12 and the first embedded component 221. The first embedded component 221 may be a plurality of embedded columns or a plurality of embedded plates, which match the plurality of embedded grooves 12. Alternatively, the first embedded component 221 may be a continuous annular structure, which is embedded in the peripheral side surface of the impeller 1, and the embedding groove 12 may also be an annular receiving groove structure. Those skilled in the art may set it according to actual conditions.

[0078] See also Figure 1 and Figure 3 ,like Figure 1 and Figure 3 As shown, a plurality of protrusions 11 are arranged on the peripheral side of the impeller disk 1, and the plurality of protrusions 11 are arranged circumferentially around the impeller disk 1 and are evenly distributed. A through hole 222 is arranged at a position corresponding to the protrusion 11 of the first flexible portion 2, and the protrusion 11 passes through the through hole 222 and extends to the outside of the through hole 222. Specifically, the protrusion 11 extends in a direction away from the center of the impeller disk 1, and the distance between the side of the protrusion 11 away from the center of the impeller disk 1 and the center of the impeller disk 1 is greater than the distance between the outer side of the peripheral side portion 22 and the center of the impeller disk 1. In other words, Figure 1The indicated direction is the reference direction. The right side of the protrusion 11 is located on the right side of the peripheral part 22. Figure 3 The indicated direction is the reference direction. The left side of the protrusion 11 is located on the left side of the peripheral part 22. When the agitator rotates, if there is an offset, the first part to be rubbed is the protrusion 11, preventing the peripheral part 22 of the first flexible part 2 from being worn.

[0079] Furthermore, the position height of the protrusion 11 is higher than that of the embedding groove 12, such that the first embedding member 221 is located below the protrusion 11. There is a wear-resistant part 13 to protect the lower part of the first embedding member 221, and there is a protrusion 11 to protect the side of the first embedding member 221 away from the center of the agitator disk 1, preventing the first embedding member 221 from detaching under the action of external force, and further enabling the first flexible part 2 to fit more firmly on the agitator disk 1.

[0080] Next, refer to Figure 2 and Figure 3 . Multiple water deflecting blades 14 are provided on the agitator disk 1. The multiple water deflecting blades 14 are arranged circumferentially around the center of the agitator disk 1, and the first flexible part 2 covers the surfaces of the multiple water deflecting blades 14. Specifically, the water deflecting blade 14 is a structure that protrudes upward from the agitator disk 1. The number of water deflecting blades 14 is set to 4, and the 4 water deflecting blades 14 are arranged circumferentially around the center of the agitator disk 1 and are evenly distributed. The surface disk 21 covers the water deflecting blades 14 and the upper surface of the agitator disk 1, and the area of the water deflecting blades 14 covered by the surface disk 21 and other areas on the upper surface of the agitator disk 1 are continuously and smoothly transitioned.

[0081] Next, refer to Figure 2 and 4 . As shown in Figure 2 and 4 , multiple first drainage holes 15 are provided on the agitator disk 1, and multiple second drainage holes 211 are provided on the first flexible part 2. The multiple first drainage holes 15 and the multiple second drainage holes 211 are in one-to-one communication. The first drainage holes 15 penetrate the agitator disk 1 vertically, the second drainage holes 211 are provided on the surface disk 21 and penetrate the surface disk 21 vertically, and the first drainage holes 15 and the second drainage holes 211 are in communication for drainage.

[0082] Furthermore, a flanging structure 212 is connected to the side of the second drainage hole 211 close to the agitator disk 1. Figure 4 The indicated direction is the reference direction. The flanging structure 212 is connected to the lower part of the second drainage hole 211. The second drainage hole 211 is partially embedded in the first drainage hole 15, and the flanging structure 212 covers around the first drainage hole 15. The flanging structure 212 is a sheet-like circular ring structure, closely attached to the lower part of the first drainage hole 15. The setting of the flanging structure 212 can improve the connection stability between the first flexible part 2 and the agitator disk 1 without hindering drainage, preventing the first flexible part 2 from falling off.

[0083] Next, refer to Figures 3 to 6 , as shown in Figures 3 to 6 , the impeller disk 1 includes an impeller body 17 and a detachable cover 3 disposed at the central portion of the impeller body 17. The first flexible portion 2 covers the upper surface (except the area of the cover 3) and the circumferential side surface of the impeller body 17. The cover 3 is covered with a second flexible portion 4. When the cover 3 is connected to the impeller body 17 in place, the first flexible portion 2 and the second flexible portion 4 form a smooth surface. Specifically, the impeller body 17 is disc-shaped, and its central portion protrudes upward. The cover 3 is disposed in the installation groove 16 at the central portion of the impeller body 17. Bolt holes (not shown in the figure) are provided in the installation groove 16. Bolts are inserted through the bolt holes to fix the impeller body 17 and a motor (not shown in the figure) for driving the impeller to rotate. The first flexible portion 2 is provided with a plurality of first engaging members 24. The shape of the second flexible portion 4 can match the cover 3. A plurality of second engaging members 41 are provided around the second flexible portion 4. When the cover 3 is connected to the installation groove 16 in place, the first engaging members 24 and the second engaging members 41 are engaged, and the connection portion between the first flexible portion 2 and the second flexible portion 4 forms a continuous and smooth surface, so that the first flexible portion 2 and the second flexible portion 4 can completely cover the upper surface of the impeller disk 1.

[0084] It should be noted that the present invention does not impose any restrictions on the specific structures of the first engaging member 24 and the second engaging member 41. One of the first engaging member 24 and the second engaging member 41 is a clamping post or a clamping block, and the other of the first engaging member 24 and the second engaging member 41 is a clamping hole. Those skilled in the art can set it according to the actual situation.

[0085] As shown in Figure 6 , in another preferred embodiment, the second flexible portion 4 includes a second embedding member 42. The second embedding member 42 is embedded in the cover 3. A groove-like structure matching the second embedding member 42 is provided on the cover 3. The columnar structure or plate-like structure of the second embedding member 42, or an annular plate-like structure, is embedded in the groove-like structure of the cover 3. The embedding direction of the second embedding member 42 (horizontally left and right and embedded into the cover 3) is perpendicular to the detachment direction of the second flexible portion 4 (detaching upward).

[0086] In another feasible embodiment, the cover 3 is non-detachable, that is, the cover 3 and the impeller body 17 are integrally provided, and the first flexible portion 2 and the second flexible portion 4 are also integrally provided.

[0087] Furthermore, a bending portion 23 is provided on the first flexible portion 2. The bending portion 23 is located in the installation groove 16. The bending portion 23 hooks the edge of the installation groove 16, improving the connection stability between the first flexible portion 2 and the impeller disk 1, and further preventing the first flexible portion 2 from detaching.

[0088] When installing the first flexible part 2, snap the flanging structure 212 under the first drain hole 15, snap the first embedding member 221 into the embedding groove 12, and snap the protrusion 11 into the through hole 222. After being installed in place, the first flexible part 2 is stably and firmly connected to the wave wheel disc 1 and is not likely to fall off. It is also possible that the first flexible part 2 and the wave wheel disc 1 are integrally formed by two-color injection molding. Similarly, in the embodiment with the second flexible part 4, the second flexible part 4 and the cover body 3 are integrally formed by two-color injection molding.

[0089] In a second aspect, the present invention also claims to protect a washing tub assembly, which includes a tub body 5 and a rotatable wave wheel disposed in the tub body 5, and the wave wheel is the wave wheel described in any one of the above embodiments.

[0090] Refer to Figure 7 and 8 , as Figure 7 and 8 shown, a plurality of lifting ribs 6 are provided on the inner wall of the tub body 5, and the surface of the lifting ribs 6 is covered with a third flexible part 7. Specifically, the lifting ribs 6 are arranged circumferentially inside the tub body 5 and are evenly distributed, and the lifting ribs 6 are inclined in the height direction of the tub body 5. When the wave wheel rotates, a scroll water flow will be formed, which will drive the clothes to tumble and rotate in the tub body 5. The rotation direction of the tub body 5 is opposite to that of the wave wheel to increase the washing effect. During this process, the lifting ribs 6 in the tub body 5 play a role in guiding the movement of the clothes, moving along their extending direction. Since the lifting ribs 6 themselves show an upward trend, the clothes are continuously lifted, reducing the degree of extrusion between the clothes and releasing the space in the tub body 5. When the clothes reach the highest point, they fall to the bottom of the tub body 5 under the action of gravity, forming a slapping effect. Since the lifting ribs 6 directly contact the clothes, in order to avoid abrasion of the clothes by the lifting ribs 6, a layer of the third flexible part 7 is covered on the surface of the lifting ribs 6. The third flexible part 7 is embedded into the inner wall of the tub body 5 through a third embedding member 71. The third embedding member 71 includes a first embedding part 711 and a second embedding part 712 that are connected and perpendicular to each other. The embedding direction of the second embedding part 712 is perpendicular to the falling-off direction of the third flexible part 7, enhancing the connection stability between the third flexible part 7 and the lifting ribs 6.

[0091] In another feasible example, the lifting ribs 6 are detachably connected to the inner wall of the tub body 5. Taking Figure 8 the direction shown as the reference direction, screw holes are provided below the lifting ribs 6, and threaded holes penetrating the tub body 5 are provided at corresponding positions of the tub body 5. Screws are inserted upward from the bottom of the tub body 5 into the threaded holes and the screw holes to fix the lifting ribs 6 on the inner wall of the tub body 5. In this case, the lifting ribs 6 and the third flexible part 7 are integrally formed by two-color injection molding.

[0092] The first flexible part 2, the second flexible part 4 and the third flexible part 7 are preferably made of thermoplastic silicone elastomer (TPV-Si / TPU). Thermoplastic silicone elastomer (TPV-Si / TPU) is a stable TPV polymer alloy material formed by uniformly dispersing vulcanized silicone rubber particles in the thermoplastic material TPU through dynamic vulcanization cross-linking technology. It can be formed by injection molding or extrusion molding and has excellent heat resistance, weather resistance, low surface energy, stain resistance and wear resistance.

[0093] Table 1: Characteristics of materials that the first flexible part 2, the second flexible part 4 and the third flexible part 7 can adopt.

[0094] As can be seen from Table 1, according to the standards in Table 1, the Shore A hardness of the materials that the flexible part can adopt is between 50A and 90A; the tensile strength is greater than or equal to 11 MPa; the elongation at break of the material used for the first flexible part is greater than or equal to 600%; the compression set is less than or equal to 20%; the Akron abrasion is less than or equal to 0.1 cm -3 ·1.61 km -1 ; the friction resistance ΔL is less than or equal to 0.3.

[0095] In another preferred embodiment, the material hardness of the first flexible part 2, the second flexible part 4 and the third flexible part 7 is less than the material hardness of the agitator, and a soft or elastic material is used, which can be one or any combination or all of the 6 material characteristics in Table 1. Those skilled in the art can set it according to the actual situation.
