[0053] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] As Figures 1 to 11 shown, the present invention also provides a washing tub assembly of a washing machine, and the washing tub assembly includes an inner tub 1 and an inner tub cover 11.

[0055] One end of the inner tub 1 has an opening. The peripheral wall of the opening end of the inner tub 1 is provided with dehydration holes 12. The inner tub cover 11 is arranged on the opening end of the inner tub 1 for closing or opening the opening. The inner tub 1 can be used to hold water below the dehydration holes 12, and it is a non-porous inner tub 1. When the washing machine is dehydrating, the rotation of the inner tub 1 can drive the water flow to rise along the inner peripheral wall of the inner tub 1 to the dehydration holes 12 and drain away, realizing that the outside of the inner tub 1 is not easily wetted for a long time and avoiding the deposition of dirt.

[0056] The inner peripheral wall of the inner tub 1 is provided with a guiding portion 13 arranged in a concave manner. The guiding portion 13 extends from the bottom of the inner tub 1 towards the opening end. The first side wall 131 on one side of the extending direction of the guiding portion 13 is inclined and extends for guiding the water flow towards the dehydration holes 12 during dehydration.

[0057] In the present invention, an inner barrel cover 11 is provided on the opening of the inner barrel 1, and dehydration holes 12 are provided at the opening end of the inner barrel 1. The inner barrel cover 11 can block the upward overflow of water during the dehydration of the inner barrel 1. A recessed guiding portion 13 is provided on the inner peripheral wall of the inner barrel 1, and the guiding portion 13 extends from the bottom of the barrel towards the opening end. When the inner barrel 1 rotates during dehydration, the centrifugal force generated drives the water flow to rise along the first side wall 131 of the guiding portion 13 to the dehydration holes 12, which can accelerate the drainage speed, improve the drainage efficiency, have a low structural cost, and also increase the washing effect and improve the washing ratio.

[0058] As Figures 1 to 4 shown, the inclination direction of the first side wall 131 of the guiding portion 13 is opposite to the dehydration rotation direction of the inner barrel 1.

[0059] When the inner barrel 1 rotates during dehydration, the water on the clothes detaches under the action of inertia and moves in the direction opposite to the rotation direction of the inner barrel 1, along the first side wall 131 opposite to the rotation direction of the inner barrel 1, and rises along the first side wall 131 to the dehydration holes 12 at the opening end. Cooperating with the rotation direction of the inner barrel 1, it accelerates the drainage rate and guides the water detached from the clothes to be quickly discharged.

[0060] The first side wall 131 may be inclined upward along a straight line, and the inclination angle between the first side wall 131 of the guiding portion 13 and the horizontal plane is 20° - 80°.

[0061] The first side wall 131 may also be inclined upward in an arc shape. The inclination angle between the bottom end of the first side wall 131 and the horizontal plane is 20° - 80°, or the inclination angle between the connecting line of the bottom end and the top end of the first side wall 131 and the horizontal plane is 20° - 80°.

[0062] Preferably, the inclination angle between the first side wall 131 of the guiding portion 13 and the horizontal plane is 30° - 60°. The first side wall 131 extends obliquely along the counterclockwise direction from the bottom of the inner barrel 1.

[0063] The second side wall 132 on the other side of the extending direction of the guiding portion 13 extends vertically from the bottom of the inner barrel 1 towards the opening end along the axis. During the process of the guiding portion 13 extending towards the opening end, the first side wall 131 of the guiding portion 13 extends obliquely and gradually moves away from the second side wall 132 of the guiding portion 13.

[0064] The bottom of the guiding portion 13 of the present invention is narrow and the upper end is wide, which can collect the detached water at the bottom and then discharge the detached water by rising along the first side wall 131. The guiding portion 13 can also increase the contact washing area with the clothes during the washing process.

[0065] The inner tub 1 is arranged in a flared and inclined manner, with the inner diameter gradually increasing from the bottom of the tub to the open end. In cooperation with the concave guiding portion 13 provided on the inner peripheral wall of the inner tub 1, it is more conducive to the water flow in the inner tub 1 to easily flow upward during dehydration and be discharged more quickly from the dehydration holes 12.

[0066] The peripheral wall of the inner tub 1 is inclined outward at an angle of 1° - 5° in the vertical direction of the central axis.

[0067] The dehydration holes 12 are round holes or square holes, etc., and no additional drainage holes are provided on the peripheral wall of the inner tub 1 below the dehydration holes 12.

[0068] Furthermore, the guiding portion 13 extends from the bottom of the inner tub 1 to the dehydration holes 12 of the inner tub 1, and the first side wall 131 of the guiding portion 13 extends obliquely into the dehydration holes 12.

[0069] In the present invention, by extending the guiding portion 13 from the bottom of the inner tub 1 to the dehydration holes 12 of the inner tub 1, the extension length of the first side wall 131 is increased, and the end of the first side wall 131 directly extends into the dehydration holes 12. During dehydration, the water flow at the bottom of the inner tub 1 can directly rise along the first side wall 131 to the dehydration holes 12, further improving the dehydration efficiency of the inner tub 1.

[0070] The inner tub 1 includes a connected bottom wall of the tub and a cylindrical body with openings at both ends. The bottom wall of the tub and the cylindrical body are integrally injection - molded, and the guiding portion 13 is provided on the inner peripheral wall of the cylindrical body.

[0071] The inner tub 1 is made of plastic and is integrally injection - molded. By providing the guiding portion 13 on the inner peripheral wall of the cylindrical body, the strength of the inner tub 1 can be improved, and it is convenient to demold during the production of the plastic tub, greatly improving the production efficiency and reducing the production cost.

[0072] As Figure 5 shown, the bottom of the inner tub cover 11 is snap - fitted on the opening, and the bottom wall of the inner tub cover 11 protrudes outward from the outer peripheral wall of the inner tub 1. The inner tub cover 11 has a water - retaining plate 114, which extends downward from the outer peripheral edge of the bottom wall of the inner tub cover 11 protruding from the outer peripheral wall of the inner tub 1 to the dehydration holes 12.

[0073] In the present invention, by providing the water - retaining plate 114 on the inner tub cover 11, when the washing machine is a double - tub washing machine and the inner tub 1 is arranged in the outer tub 4, there is no water between the inner tub 1 and the outer tub 4 during washing. When the inner tub 1 is dehydrated, after the water is discharged from the dehydration holes 12, the water - retaining plate 114 can guide the water flow flowing out from the dehydration holes 12 to flow downward into the outer tub 4, preventing the water discharged from the dehydration holes 12 from hitting the outer tub 4 and splashing water.

[0074] As Figures 6 to 8As shown, the washing tub assembly further includes a support frame 2, which is rotatably fixed in the outer tub 4, enabling convenient and rapid replacement of the inner tub 1, achieving partitioned washing, and avoiding cross-contamination.

[0075] The support frame 2 has a receiving cavity, and a balance ring 3 is provided at the inlet at one end of the receiving cavity. The inner tub 1 is detachably fixed in the receiving cavity of the support frame 2 and is circumferentially limited with the support frame 2. The bottom of the inner tub 1 enters the receiving cavity through the inlet. During the dehydration of the washing machine, it drives the water flow to rise along the first side wall 131 on the inner peripheral wall of the inner tub 1 and is discharged through the dehydration holes 12.

[0076] By adding the support frame 2 in the present invention, the support frame 2 can be rotatably fixed inside the outer tub 4 of the washing machine, and the bottom end of the inner tub 1 is detachably fixed in the support frame 2, reducing the space occupied by the support frame 2 in the washing machine. The balance ring 3 is provided at the inlet of the support frame 2, and the support frame 2 can play a role in fixing the inner tub 1. It has a small structural volume and low cost, and can realize replacing the inner tub 1 to wash clothes separately, avoiding cross-infection. The replaceable inner tub 1 greatly improves the application of personalized scenarios and enhances the user experience.

[0077] Furthermore, the balance ring 3 on the support frame 2 is lower than the height of the opening of the inner tub 1. The axial height of the support frame 2 is much smaller than the axial height of the inner tub 1.

[0078] Preferably, the balance ring 3 on the support frame 2 is lower than the height of the dehydration holes 12 of the inner tub 1. The upper edge of the support frame 2 is also lower than the height of the dehydration holes 12 of the inner tub 1.

[0079] In the present invention, the balance ring 3 on the support frame 2 is lower than the height of the dehydration holes 12 of the inner tub 1, so that the balance ring 3 on the support frame 2 avoids occupying the space outside the outer periphery of the inner tub cover 11. Compared with the existing balance ring 3 arranged on the middle tub between the inner tub 1 and the outer tub 4, it can avoid reducing the washing capacity of the inner tub 1, and can also facilitate the dehydration of the inner tub 1 and avoid the water reflected from the dehydration holes 12 splashing onto the support frame 2.

[0080] The inner peripheral side of the receiving cavity of the support frame 2 has protrusions 21 extending to both axial ends, and a concave chute 15 is provided on the outer peripheral wall at the bottom end of the inner tub 1, which is slidably clamped on the protrusions 21 inside the support frame 2.

[0081] On the inner peripheral side of the accommodation cavity of the support frame 2, there are protrusions 21 extending to both axial ends. On the outer peripheral wall at the bottom end of the inner barrel 1, there is a recessed sliding groove 15, which is arranged to extend axially. The sliding groove 15 is slidably clamped on the protrusions 21 inside the support frame 2 from the inlet of the accommodation cavity, which not only facilitates the quick disassembly and assembly of the inner barrel 1 and the support frame 2, but also can prevent the inner barrel 1 from rotating circumferentially relative to the support frame 2, preventing the inner barrel 1 from rotating, shifting, and shaking.

[0082] Further, a plurality of guiding portions 13 are provided on the peripheral wall of the inner barrel 1 at circumferential intervals. The guiding portions 13 protrude from the inner side to the outer side of the inner barrel 1, forming a recessed portion on the inner side and a protruding portion 14 on the outer side.

[0083] The area between adjacent protruding portions 14 on the outer side of the inner barrel 1 forms the sliding groove 15. The sliding groove 15 of the inner barrel 1 is installed on the protrusions 21 from top to bottom.

[0084] In the present invention, by protruding the guiding portions 13 from the inner side to the outer side of the inner barrel 1 to form a plurality of protruding portions 14 on the outer side, a plurality of recessed areas are formed on the inner peripheral wall of the inner barrel 1, which facilitates the water flow to rise along the first side wall 131 of each recessed area and discharge from the dehydration holes 12, accelerating the water flow discharge. Also, a plurality of protruding portions 14 can be formed on the outer peripheral wall of the inner barrel 1, and the sliding groove 15 is formed between adjacent protruding portions 14. When cooperating with the support frame 2 for installation, it is convenient for integral injection molding. At the same time, the sliding groove 15 and the guiding portions 13 are formed, and there is no need to separately process the sliding groove 15, with simple processing and low cost.

[0085] Preferably, the protrusions 21 on the support frame 2 match the sliding grooves 15 on the inner barrel 1. Both the protrusions 21 and the sliding grooves 15 extend from the bottom to the inlet end, and the outer diameters gradually decrease. The extending length of the sliding groove 15 is greater than the extending length of the protrusions 21. When the inner barrel 1 is installed into the support frame 2, the sliding groove 15 at the bottom end of the inner barrel 1 aligns with the protrusions 21 on the support frame 2 and is slidably clamped on the protrusions 21 from top to bottom with the inner diameter gradually decreasing.

[0086] There are 2 - 6 guiding portions 13 provided on the inner peripheral wall of the inner barrel 1. A handle 16 is provided at the open end of the inner barrel 1.

[0087] The support frame 2 includes a bottom plate 22, a plurality of connecting plates 24, and an annular plate 23. One ends of the plurality of connecting plates 24 are arranged at circumferential intervals on the outer peripheral edge of the bottom plate 22, and the other ends extend axially. The annular plate 23 is connected to the other ends of the plurality of connecting plates 24 to form the accommodation cavity. By connecting the bottom plate 22, the connecting plates 24, and the annular plate 23 to form a frame - type support frame 2, the manufacturing cost can be reduced, and it is convenient for the disassembly and assembly with the inner barrel 1.

[0088] The inner side wall of the connecting plate 24 protrudes inwardly from the annular plate 23 to form the protrusion 21, which is slidably clamped in the chute 15. The protruding part 14 of the inner barrel 1 is installed between two adjacent connecting plates 24.

[0089] The multiple connecting plates 24 extend from the bottom end of the support frame 2 towards the inlet end, and the width gradually decreases. The thickness of the connecting plate 24 in the radial direction is greater than the thickness of the annular plate 23.

[0090] One side wall of the connecting plate 24 in the extending direction matches the first side wall 131 of the guiding part 13.

[0091] The protruding part 14 is clamped in the gap between two adjacent connecting plates 24 of the support frame 2, further limiting the circumferential movement of the inner barrel 1 and the support frame 2.

[0092] Preferably, a pulsator hole 222 is provided on the bottom plate 22, and a pulsator input shaft 51 extending outward is passed through. A fixing hole 223 is provided on the outer periphery of the pulsator hole 222 for connecting with the dewatering shaft 61 of the speed reduction clutch 6. The shape of the inner side wall of the connecting plate 24 matches the bottom end of the chute 15, and it is slidably clamped at the bottom end of the chute 15.

[0093] Further, corresponding drain holes and mounting holes that can be opened and closed are provided at the bottom of the inner barrel 1 and on the support frame 2, that is, the mounting holes are provided on the bottom plate 22. The drain holes can be closed or opened by inserting a plug through the mounting holes, so that the inner barrel 1 can hold water or quickly drain water from the bottom.

[0094] Preferably, a support foot 17 protruding towards the bottom wall of the support frame 2 is provided at the outer peripheral edge of the bottom of the inner barrel 1. By providing the support foot 17 outside the bottom of the inner barrel 1, the transportation or placement of the inner barrel 1 can be facilitated, and the inner barrel 1 can be prevented from being damaged. There is an annular cavity 221 on the bottom wall inside the support frame 2, and the support foot 17 is inserted into the annular cavity 221.

[0095] Reinforcing ribs are provided outside the bottom of the inner barrel 1, including an annular reinforcing rib provided at the outer peripheral edge of the bottom of the barrel and reinforcing ribs connected to the inner peripheral wall of the annular reinforcing rib. Through holes penetrating the inner and outer peripheral sides are provided on the annular reinforcing rib.
