Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a washing tub assembly, and also relates to a washing device having the washing tub assembly. Background Art

[0002] A pulsator washing machine typically includes a washing tub and a pulsator, which is located at the bottom of the tub. The pulsator and the drum rotate relative to each other, driving the wash water and clothing within the tub, thereby washing the laundry. Existing pulsators are typically flat, circular pulsators. During washing, dirt, lint, and other impurities from the laundry easily accumulate in the gap between the bottom of the pulsator and the tub, making them ineffective for simple rinsing. Furthermore, dirt and lint left in a humid environment for extended periods can easily breed bacteria, resulting in a poor user experience. For thorough cleaning, the pulsator must be removed to scrub the dirt from the gap, a complex operation that further degrades the user experience. Furthermore, in these pulsator washing machines, the laundry is completely positioned above the pulsator, covering a large area of ​​the pulsator surface. The friction between the pulsator and the laundry drives the laundry through the wash water, which can increase entanglement and wear. Furthermore, the friction between the laundry and the pulsator increases the energy consumption of the drive motor required to rotate the pulsator.

[0003] To solve the above problems, the manufacturer has developed a water-stirring component that eliminates the bottom disc-shaped stirring part, so that the surface of the water-stirring component below its maximum radius and the inner surface of the barrel bottom at the periphery of the water-stirring component can come into contact with the laundry in the barrel, and the friction between the clothes and the two can prevent lint or other dirt from adhering to the surfaces of the two.

[0004] However, when the water stirring member is used on a hole-free drum washing machine, the drain outlet on the washing drum will be directly exposed to the washing surface at the bottom of the drum. When draining, the drain valve will open the drain outlet, and the clothes in the inner drum will easily enter the drain outlet, causing the drain valve to be unable to be completely closed, thereby causing water leakage.

[0005] At the same time, debris such as lint will enter the drain with the washing water, which can easily cause blockage of the drain, drainage pipes and floor drains in the user's home.

[0006] Therefore, designing a washing tub assembly that can prevent debris such as clothes and thread scraps in the tub from entering the drain port during drainage has become a technical problem that needs to be urgently solved by those skilled in the art.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The present invention provides a washing tub assembly. By arranging a valve plug to be embedded in a drain outlet, the valve plug can reduce the scratching of clothes by the valve plug during the washing process. When the valve plug moves to the open position, the washing water is discharged from the drain hole on the side of the valve plug, which can prevent clothes, lint and other debris from entering the drain outlet. This solves the problem that in the existing washing tub assembly, clothes in the tub easily enter the drain outlet when draining, preventing the drain valve from closing the drain outlet, and lint and other debris from entering the drain outlet, causing blockage of the drain outlet, drainage pipeline and floor drain in the user's home.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] A washing tub assembly comprising:

[0011] Washing tub, which holds washing water independently when washing clothes;

[0012] A water stirring member extends along the axial direction of the washing tub, with its lower end rotatably mounted on the tub bottom;

[0013] A drain outlet is provided on the bottom of the barrel, extending outward from the lower end of the water stirring member to the barrel wall. A drain valve is provided at the drain outlet. The drain valve includes a sealing position in which the valve plug is downwardly embedded in the drain outlet, and an open position in which the valve plug protrudes upward from the inner surface of the barrel bottom.

[0014] A drainage hole is provided on the periphery of the valve plug of the drainage valve.

[0015] Furthermore, the valve plug comprises:

[0016] The top wall has the same shape as the drain outlet and is substantially flush with the inner surface of the barrel bottom at the periphery of the drain outlet;

[0017] A surrounding wall extends downward from the edge of the top wall, and drainage holes are provided on the surrounding wall, wherein the plurality of drainage holes are arranged at intervals along the circumference of the valve plug;

[0018] Preferably, the drainage hole is configured as a waist-shaped hole extending along the axial direction of the surrounding wall, and a plurality of drainage holes are evenly arranged along the circumference of the valve plug.

[0019] Furthermore, the valve plug further includes a sealing portion;

[0020] The lower end of the drain outlet is provided with a reduced diameter portion extending toward the middle of the drain outlet, and the sealing portion is provided on the inner periphery of the surrounding wall and elastically abuts against the reduced diameter portion; and / or,

[0021] The lower end of the drain outlet is provided with a reduced diameter portion extending toward the middle of the drain outlet, and the sealing portion is provided at the lower end of the surrounding wall and elastically abuts against the reduced diameter portion; and / or,

[0022] The sealing portion is arranged on the outer periphery of the top wall and elastically contacts the inner wall of the upper end of the drain outlet.

[0023] Furthermore, the sealing part is arranged on the inner periphery of the surrounding wall and spaced apart from the surrounding wall. The inner periphery of the reduced diameter part extends to just below the sealing part. The upper end of the sealing part is connected to the top wall, and the lower end is elastically in contact with the reduced diameter part.

[0024] Furthermore, the sealing portion includes:

[0025] The sealing rib is annular and extends downward from the top wall of the inner periphery of the surrounding wall and is spaced apart from the surrounding wall;

[0026] The sealing sleeve is annular and is placed on the sealing rib, with its top fitting against the inner side of the top wall of the valve plug;

[0027] Preferably, the upper end of the sealing sleeve on the inner periphery of the sealing rib extends along the inner side of the top wall of the valve plug in a direction close to the axis of the drain outlet.

[0028] Furthermore, the diameter-reduced portion is inclined downward along an extending direction of the axis close to the drain outlet.

[0029] Furthermore, it also includes: a supporting component, one end of which is fixedly mounted on the bottom of the washing tub, and the other end of which extends below the drain outlet, and the valve plug of the drain valve is relatively slidably mounted on the supporting component;

[0030] an elastic component, disposed between the valve plug and the supporting component, and configured to drive the valve plug to move downward;

[0031] The driving component is used to drive the valve plug to move upward.

[0032] Furthermore, the supporting member includes:

[0033] A fixing portion, a first end of which is fixedly mounted on the bottom of the washing tub and a second end of which extends below the drain outlet;

[0034] The sleeve portion is fixedly connected to the second end of the fixed portion and has a hollow slideway. A sliding rod is provided at the bottom of the valve plug of the drain valve, and the sliding rod is slidably provided in the hollow slideway of the sleeve portion.

[0035] The elastic component is arranged between the sleeve portion and the sliding rod.

[0036] Furthermore, the water stirring member has a maximum radius in the radial direction of the washing tub at a certain distance from the inner surface of the tub bottom, and a first guide surface is formed on the lower side of the stirring member, extending from a region close to the axis toward the periphery, for guiding the clothes below the stirring member to move toward the periphery along the first guide surface during washing;

[0037] A second guide surface extending upward is formed below the first guide surface, for guiding the clothes to move along the second guide surface toward the first guide surface during washing.

[0038] The present invention also provides a washing device, comprising the washing tub assembly; and

[0039] The driving device is respectively connected to the washing tub and the water stirring member, and is used to drive the washing tub and the water stirring member to rotate simultaneously or alternately during washing, driving at least part of the clothes to move in an area below the maximum radius of the water stirring member for washing.

[0040] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0041] 1. The present invention reduces the possibility of the valve plug scratching clothes by inserting the valve plug into the drain outlet. When the valve plug moves to the open position, washing water is discharged from the drainage holes around the valve plug, preventing debris such as clothes and lint from entering the drain outlet. This prevents clothes in the washing tub from obstructing the drain valve from closing the drain outlet, thereby improving the working stability of the drain valve. At the same time, it has a filtering effect on debris such as lint in the washing water, preventing them from entering the drain outlet and causing blockage of the drain outlet, drainage pipes, and floor drains in the user's home.

[0042] 2. The present invention arranges the sealing part on the inner periphery of the surrounding wall and is spaced apart from the surrounding wall. When draining water, the top wall of the valve plug and the surrounding wall can be used to stop the clothes, thereby preventing the clothes from entering between the sealing part of the valve plug and the reduced diameter part of the bottom of the barrel, and preventing the clothes from obstructing the seal between the sealing part and the reduced diameter part.

[0043] 3. In the present invention, the maximum radius of the water-stirring member within the washing tub is located a certain distance from the tub bottom. During washing, the drive device drives the washing tub and the water-stirring member to rotate relative to each other, driving the laundry to move below the maximum radius of the water-stirring member for washing. This allows the laundry to fully contact the outer surface of the water-stirring member and the inner wall of the washing tub below the maximum radius, effectively avoiding the problem of dirt and grime easily accumulating between the water-stirring member and the tub bottom, making cleaning difficult and improving the user experience. Furthermore, the laundry does not extensively cover the water-stirring member, reducing the resistance to the water-stirring member's rotation, thereby reducing energy consumption of the motor used by the drive device to rotate the water-stirring member.

[0044] At the same time, the present invention has a simple structure, significant effects, and is suitable for popularization and use.

[0045] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0053] like Figures 1 to 11 As shown, an embodiment of the present invention introduces a washing machine, which includes at least a washing tub 100, a water stirring member 200, and a driving device. The washing tub 100 is used to accommodate laundry, and the water stirring member 200 is rotatably disposed within the washing tub 100. When the washing machine is in operation, the rotation of the water stirring member 200 drives the washing water in the washing tub 100 to rotate, thereby washing the laundry in the washing tub 100.

[0054] In this embodiment, the washing tub 100 is a non-porous tub. During washing, the washing tub 100 independently holds wash water. Specifically, the washing apparatus of this embodiment includes the washing tub 100 and a water collection device. A drain port 100-32 is defined at the bottom of the washing tub 100. During washing, no water flows between the washing tub 100 and the water collection device. During drainage and dehydration, water in the washing tub 100 enters the water collection device and is discharged therefrom. In this embodiment, the water collection device can be an external tub or located solely at the bottom of the washing tub 100. This allows the washing water in the washing tub 100 to flow into the water collection device before being discharged. Thus, the water collection device temporarily stores water, and the height of the water collection device is less than that of the washing tub 100.

[0055] The driving device of the washing equipment is respectively connected to the washing tub 100 and the water stirring member 200 for driving the washing tub 100 and the water stirring member 200 to rotate.

[0056] More specifically, the output shaft of the drive device is connected to the agitator shaft 300 and the spindle shaft. The agitator shaft 300 is connected to and fixed relative to the agitator member 200, driving the agitator member 200 to rotate. The spindle shaft is fixed to the bottom of the washing tub 100, driving the washing tub 100 to rotate.

[0057] During washing, the drive device drives the stirring shaft 300 and the spin shaft to rotate simultaneously or alternately, which in turn drives the water stirring member 200 and the washing tub 100 to rotate simultaneously or alternately. The relative rotation between the water stirring member 200 and the washing tub 100 stirs the clothes and the wash water in the tub, effectively cleaning the clothes. During the spin cycle, the drive device drives the stirring shaft 300 and the spin shaft to rotate synchronously at high speed, which in turn drives the water stirring member 200 and the washing tub 100 to rotate synchronously at high speed, using centrifugal force to spin dry the clothes in the tub.

[0058] However, when washing clothes, lint and dirt are mixed into the wash water. If there is a relatively narrow gap between the agitating member 200 and the washing tub 100, these lint and dirt can easily hide in the gap and be difficult to be removed by the impact of the water flow during the washing process. Over time, this gap between the agitating member 200 and the washing tub 100 can trap dirt and bacteria, causing secondary contamination of the clothes.

[0059] Example 1

[0060] like Figures 1 to 4 As shown, in an embodiment of the present invention, a washing tub 100 assembly is introduced. The washing tub 100 assembly includes a washing tub 100 and a water stirring member 200 installed on the bottom of the washing tub 100. The washing tub 100 assembly is applied to a washing device.

[0061] In this embodiment, the washing tub 100 is a tub without holes, which independently holds washing water during washing. The water stirring member 200 extends along the axial direction of the washing tub 100, and its lower end is rotatably mounted on the tub bottom.

[0062] In this embodiment, the bottom of the tub is provided with a drain port 100-32 and a drain valve 600 for keeping the drain port 100-32 normally closed. Specifically, the drain port 100-32 is provided in the area of ​​the tub bottom extending outward from the lower end of the water-stirring member 200 to the tub wall. That is, the drain port 100-32 of the washing tub 100 is provided on the washing surface 100-31 of the tub bottom, eliminating the disc-shaped stirring portion 231 at the bottom. This prevents the water-stirring member 200 from obstructing the flow of wash water to the drain port 100-32 on the washing surface 100-31, thereby improving drainage speed.

[0063] A drain valve 600 is provided at the drain outlet 100-32. The washing tub 100 is self-sealed through the drain valve 600, so that when the washing equipment is working, no water will accumulate between the washing tub 100 and the water collection device, thereby preventing contamination. It is also an application of water-saving technology for users. In addition, after the washing tub 100 is self-sealed through the drain valve 600, the washing tub 100 and the water stirring member 200 can rotate relative to each other, realizing the function of dual-power washing clothes.

[0064] like Figure 1 and Figure 2 As shown, in this embodiment, the drain valve 600 includes a blocking position where the valve plug 600-1 is downwardly embedded in the drain outlet 100-32, and an open position where the valve plug 600-1 protrudes upward from the inner surface of the barrel bottom.

[0065] Specifically, in this embodiment, the drain port 100-32 extends vertically downward to the inner surface of the bottom of the washing tub 100, having a certain extension length. The valve plug 600-1 of the drain valve 600 is shaped to match the shape of the drain port 100-32 and is embedded in the drain port 100-32. It elastically abuts against the inner wall of the drain port 100-32 and / or the inner surface of the bottom of the washing tub 100 around the drain port 100-32, thereby sealing the drain port 100-32. The valve plug 600-1 is installed in the drain port 100-32 from the inner side of the bottom of the washing tub 100, and moves downward to seal the drain port 100-32, and moves upward to open the drain port 100-32.

[0066] A drainage hole 600-13 is provided around the valve plug 600-1 of the drain valve 600. When the valve plug 600-1 moves to the open position, the valve plug 600-1 protrudes from the inner surface of the bottom of the washing tub 100, exposing the drainage hole 600-13. The washing water in the washing tub 100 enters the drain port 100-32 through the drainage hole 600-13 and is discharged.

[0067] By setting the valve plug 600-1 to be embedded in the drain outlet 100-32, the valve plug 600-1 can reduce the scratching of clothes by the valve plug 600-1. When the valve plug 600-1 moves to the open position, the washing water is discharged from the drain hole 600-13 on the side of the valve plug 600-1, which can prevent clothes, lint and other debris from entering the drain outlet 100-32, thereby preventing the clothes in the washing tub 100 from obstructing the drain valve 600 from closing the drain outlet 100-32, thereby improving the working stability of the drain valve 600. At the same time, it has a filtering effect on lint and other debris in the washing water, preventing lint and other debris from entering the drain outlet 100-32 and causing blockage of the drain outlet 100-32, the drainage pipe and the floor drain in the user's home.

[0068] In this embodiment, the valve plug 600-1 includes a top wall 600-11 and a surrounding wall 600-12. The top wall 600-11 of the valve plug 600-1 has the same shape as the drain outlet 100-32 and is basically flush with the inner surface of the barrel bottom around the drain outlet 100-32. The surrounding wall 600-12 extends downward from the edge of the top wall 600-11. The drainage hole 600-13 is set on the surrounding wall 600-12, and multiple drainage holes 600-13 are arranged at intervals along the circumference of the valve plug 600-1.

[0069] In this embodiment, the shape of the drain outlet 100-32 can be any shape, preferably an ellipse or a circle. The shape of the top wall 600-11 is the same as that of the drain outlet 100-32, and the size of the top wall 600-11 is substantially equal to that of the drain outlet 100-32. Preferably, the size of the top wall 600-11 is slightly smaller than that of the drain outlet 100-32. The surrounding wall 600-12 extends vertically downward from the edge of the top wall 600-11, corresponding to and slidingly fitting with the inner peripheral wall of the drain outlet 100-32.

[0070] The drainage hole 600 - 13 is provided on the surrounding wall 600 - 12 , and the drainage hole 600 - 13 may be a hole of any shape.

[0071] Preferably, the drainage hole 600 - 13 is configured as a waist-shaped hole extending along the axial direction of the valve plug 600 - 1 , and a plurality of drainage holes 600 - 13 are evenly arranged along the circumference of the valve plug 600 - 1 .

[0072] Preferably, in this embodiment, when the valve plug 600-1 of the drain valve 600 is in the blocking position, the upper end surface of the valve plug 600-1 is flush with the inner surface of the bottom of the washing tub 100; when the valve plug 600-1 of the drain valve 600 is in the open position, the lower end of the surrounding wall 600-12 of the valve plug 600-1 is flush with the inner surface of the bottom, or the lower end of the surrounding wall 600-12 at least partially extends below the inner surface of the bottom, thereby preventing debris such as clothes or thread scraps from entering between the lower end of the surrounding wall 600-12 and the inner surface of the bottom, thereby improving the smoothness of the valve plug 600-1 moving from the open position to the blocking position.

[0073] Preferably, in this embodiment, when the valve plug 600-1 is in the open position, the lower end of the drainage hole 600-13 is flush with the inner surface of the barrel bottom, or the lower end of the drainage hole 600-13 is lower than the inner surface of the barrel bottom, thereby ensuring smooth drainage and being able to fully drain the washing water in the washing barrel 100.

[0074] In this embodiment, the valve plug 600 - 1 of the drain valve 600 further includes a sealing portion 600 - 14 , and the valve plug 600 - 1 elastically contacts the washing tub 100 through the sealing portion 600 - 14 to block the drain port 100 - 32 .

[0075] Specifically, the lower end of the drain outlet 100-32 is provided with a reduced diameter portion 100-33 extending toward the middle of the drain outlet 100-32, and the sealing portion 600-14 is provided on the inner periphery of the surrounding wall 600-12, elastically abutting against the reduced diameter portion 100-33; and / or, the lower end of the drain outlet 100-32 is provided with a reduced diameter portion 100-33 extending toward the middle of the drain outlet 100-32, and the sealing portion 600-14 is provided on the lower end of the surrounding wall 600-12, elastically abutting against the reduced diameter portion 100-33; and / or, the sealing portion 600-14 is provided on the outer periphery of the top wall 600-11, elastically abutting against the inner wall of the upper end of the drain outlet 100-32.

[0076] Preferably, in this embodiment, in order to ensure the sealing effect of the valve plug 600-1 moving downward and blocking the drain outlet 100-32, the sealing portion 600-14 is arranged at the lower end of the surrounding wall 600-12 and / or on the top wall 600-11 of the inner periphery of the surrounding wall 600-12.

[0077] In this embodiment, the drain outlet 100 - 32 first extends vertically downward from the inner surface of the bottom of the washing tub 100 , and then contracts inward to form a reduced diameter portion 100 - 33 .

[0078] In some possible embodiments, the sealing portion 600-14 is disposed at the lower end of the surrounding wall 600-12. In this embodiment, the inner periphery of the diameter-reducing portion 100-33 extends at least to directly below the surrounding wall 600-12. When the valve plug 600-1 moves downward, the lower end of the surrounding wall 600-12 elastically abuts against the diameter-reducing portion 100-33 via the sealing portion 600-14.

[0079] In some possible embodiments, the sealing portion 600-14 is arranged on the inner periphery of the surrounding wall 600-12 and is spaced apart from the surrounding wall 600-12. The inner periphery of the reduced diameter portion 100-33 extends to directly below the sealing portion 600-14. The upper end of the sealing portion 600-14 is connected to the top wall 600-11, and the lower end is elastically abutted against the reduced diameter portion 100-33.

[0080] By arranging the sealing part 600-14 on the inner periphery of the surrounding wall 600-12 and spaced apart from the surrounding wall 600-12, the top wall 600-11 of the valve plug 600-1 and the surrounding wall 600-12 can be used to stop the clothes when draining water, thereby preventing the clothes from entering between the sealing part 600-14 of the valve plug 600-1 and the reduced diameter part 100-33 at the bottom of the barrel, and preventing the clothes from obstructing the seal between the sealing part 600-14 and the reduced diameter part 100-33. At the same time, the smoothness of the reciprocating movement of the valve plug 600-1 between the blocking position and the open position can be improved.

[0081] Preferably, in this embodiment, when the sealing portion abuts against the diameter-reduced portion, the surrounding wall and the necked portion are spaced apart.

[0082] In this embodiment, the sealing portion 600-14 comprises a sealing rib and a sealing sleeve mounted on the sealing rib. Specifically, the sealing rib is annular and extends downward from the top wall 600-11 on the inner periphery of the surrounding wall 600-12. The sealing rib and the top wall 600-11 are integrally formed, and the sealing rib and the surrounding wall 600-12 are spaced apart. The sealing sleeve is annular and mounted on the sealing rib, with the top of the sealing sleeve in contact with the inner side of the top wall 600-11 of the valve plug 600-1.

[0083] like Figure 3 and Figure 4 As shown, in this embodiment, the sealing sleeve is generally U-shaped and is mounted on the sealing rib from the lower end thereof, with its upper end abutting the inner side of the top wall 600-11. Preferably, the upper end of the sealing sleeve on the inner periphery of the sealing rib extends along the inner side of the top wall 600-11 of the valve plug 600-1 toward the axis of the drain outlet 100-32.

[0084] Preferably, in this embodiment, a water retaining rib is further provided on the top wall 600-11 of the inner periphery of the sealing rib, and the water retaining rib extends downward from the top wall 600-11. The water retaining rib and the sealing rib are spaced apart, and the inner periphery of the sealing sleeve extends along the inner side of the top wall 600-11 until it abuts against the outer peripheral wall of the water retaining rib.

[0085] Preferably, in this embodiment, the reduced diameter portion 100-33 is inclined downward along the extending direction of the axis near the drain outlet 100-32. The inner circumference of the reduced diameter portion 100-33 extends at least to directly below the sealing portion 600-14. The lower end surface of the sealing sleeve is configured as an inclined surface that is inclined downward along the direction near the inner circumference of the drain outlet 100-32 and is in contact with the reduced diameter portion 100-33.

[0086] In this embodiment, the washing tub 100 assembly further includes a support member 700, through which the drain valve 600 is mounted on the washing tub 100. Specifically, the support member 700 includes a fixing portion 700-1 and a sleeve portion 700-2. The fixing portion 700-1 is fixedly mounted on the bottom of the washing tub 100 and extends to directly below the drain outlet 100-32. The sleeve portion 700-2 is fixedly connected to the sleeve portion 700-2, which has a hollow slide. The valve plug 600-1 of the drain valve 600 includes a sealing portion 600-14 and a sliding rod 600-15. The sliding rod 600-15 is slidably disposed within the hollow slide of the sleeve portion 700-2, enabling the sealing portion 600-14 to block / open the drain outlet 100-32.

[0087] To maintain the self-sealing properties of the sealing portion 600-14 and restore the seal after drainage, the drain valve 600 includes an elastic member 600-3. One end of the elastic member 600-3 abuts against the support member 700, and the other end abuts against the valve plug 600-1. The elastic member 600-3 deforms when the sealing portion 600-14 slides away from the drain outlet 100-32, achieving elastic restoration of the sealing portion 600-14. The elastic member 600-3 is initially compressed to maintain the sealing portion 600-14 sealed against the upper end of the drain outlet 100-32.

[0088] As one implementation of this embodiment, the elastic component 600-3 is a compression spring, which is sleeved within the hollow slideway of the sleeve portion 700-2. One end of the compression spring abuts against the sleeve portion 700-2, and the other end abuts against the bottom of the valve plug 600-1. Furthermore, a screw is mounted on the end of the sliding rod 600-15. The upper end of the sleeve portion 700-2 has a stopper step extending a certain distance toward the interior of the hollow slideway. The compression spring is sleeved on the center rod, with one end abutting against the screw and the other end abutting against the stopper step.

[0089] In this embodiment, a driving component 600-2 is provided at the bottom of the water collection device, corresponding to the drain valve 600. The driving component 600-2 is used to drive the drain valve 600 to open. When the washing machine is washing, the working end of the driving component 600-2 retracts downward, separating from the valve plug 600-1 of the drain valve 600 to avoid interfering with the rotation of the washing tub 100. When the washing machine is draining, the washing tub 100 rotates to a point where the drain valve 600 corresponds to the working end of the driving component 600-2. The working end of the driving component 600-2 extends upward, pushing the valve plug 600-1 of the drain valve 600 upward, thereby opening the drain port 100-32.

[0090] Preferably, in some possible embodiments, the washing device further includes a locking component, which can lock and position the washing tub 100. After the locking component locks the washing tub 100, it is easier for the driving component 600-2 to drive the drain valve 600 to open, thereby ensuring normal drainage.

[0091] In this embodiment, the specific structure of the locking component of the washing device can adopt the structure of the locking component in the existing dual-power washing device.

[0092] Example 2

[0093] In this embodiment, a washing device is further provided to solve the problem that there is a dead corner between the water stirring member 200 and the washing tub 100 where dirt and grime are hidden and difficult to clean.

[0094] In this embodiment, the water stirring member 200 extends upward from the bottom of the washing tub 100 and is rotatably disposed in the washing tub 100. The middle or top of the water stirring member 200 has a point with the largest radius. The point with the largest radius of the water stirring member 200 faces the bottom of the tub, and the space between the two is used for washing clothes.

[0095] Specifically, the washing machine described in this embodiment includes a washing tub 100, a water-stirring member 200, and a driving device. The water-stirring member 200 is rotatably disposed within the washing tub 100, having a predetermined height along the axial direction of the washing tub 100 and a maximum radius along the radial direction of the washing tub 100 at a predetermined distance from the inner surface of the bottom of the washing tub 100. This predetermined distance allows laundry to be washed below the location of the maximum radius Rmax of the water-stirring member 200. The driving device is in transmission connection with the washing tub 100 and the water-stirring member 200, respectively. During washing, the driving device drives the washing tub 100 and the water-stirring member 200 to rotate simultaneously or alternately, thereby moving the laundry within the tub for washing.

[0096] More specifically, in this embodiment, the driving device drives the washing tub 100 and the water-stirring member 200 via a deceleration clutch device. The deceleration clutch device includes a stirring shaft 300 connected to the water-stirring member 200 and a dehydration shaft connected to the washing tub 100. During washing, the deceleration clutch device performs a washing operation. Driven by the driving device, the stirring shaft 300 and the dehydration shaft rotate simultaneously or alternately. In the case of simultaneous rotation, at least one of the rotation direction and speed differs, thereby driving relative rotation between the water-stirring member 200 and the washing tub 100 for washing. During dehydration, the deceleration clutch device performs a dehydration operation. Driven by the driving device, the stirring shaft 300 and the dehydration shaft rotate synchronously at high speed, thereby driving the water-stirring member 200 and the washing tub 100 to rotate synchronously at high speed for dehydration.

[0097] In the above solution, the specific structure of the deceleration clutch device can adopt the structure of the deceleration clutch in the existing dual-power washing equipment.

[0098] In this embodiment, the relative rotation between the washing tub 100 and the water-stirring member 200 during the washing process can be utilized to drive the clothes in the tub to move in an area below the maximum radius Rmax of the water-stirring member 200 for washing. On the one hand, the clothes can fully contact the outer surface of the water-stirring member 200 and the inner wall of the washing tub 100 below the maximum radius Rmax, effectively avoiding the problem of dirt and grime easily accumulating between the water-stirring member 200 and the bottom of the tub, making it difficult to clean, thereby improving the user experience. On the other hand, some or all of the clothes are below the maximum radius Rmax of the water-stirring member 200 during washing, rather than covering a large area above the water-stirring member 200. This can significantly reduce the resistance of the clothes to the rotation of the water-stirring member 200, thereby helping to reduce the energy consumption of the motor used by the drive device to drive the water-stirring member 200 to rotate.

[0099] As a specific embodiment, during the washing process, the driving device drives the washing tub 100 and the water stirring member 200 to rotate in opposite directions to perform washing.

[0100] Specifically, during washing, the driving device drives the water stirring member 200 to rotate alternately forward and reverse, and simultaneously drives the washing tub 100 to rotate alternately forward and reverse in the opposite direction of the water stirring member 200. When the water stirring member 200 rotates clockwise, the washing tub 100 rotates counterclockwise; conversely, when the water stirring member 200 rotates counterclockwise, the washing tub 100 rotates clockwise.

[0101] In the above embodiment, when the washing tub 100 and the water stirring member 200 rotate in opposite directions, their rotational speeds can be the same or different. In a preferred embodiment, the washing tub 100 and the water stirring member 200 rotate in opposite directions at different rotational speeds, wherein the rotational speed of the water stirring member 200 is greater than the rotational speed of the washing tub 100.

[0102] As another specific embodiment, during the washing process, the driving device drives the washing tub 100 and the water stirring member 200 to rotate in the same direction at different speeds for washing. For example, the speed of the washing tub 100 is lower than the speed of the water stirring member 200. In this way, relative rotation can also be formed between the washing tub 100 and the water stirring member 200.

[0103] Similar to the previous embodiment, the washing tub 100 and the water stirring member 200 also rotate in a forward and reverse alternating manner during the washing process. That is, the washing tub 100 and the water stirring member 200 rotate clockwise at different speeds at the same time, and then rotate counterclockwise at the same time, repeating the cycle.

[0104] As another specific embodiment, during the washing process, the driving device drives the washing tub 100 and the water-stirring member 200 to rotate alternately, that is, the washing tub 100 remains stationary when the water-stirring member 200 is driven to rotate, and the water-stirring member 200 remains stationary when the washing tub 100 is driven to rotate. In this way, relative rotation can also be generated between the washing tub 100 and the water-stirring member 200.

[0105] It should be noted that, in the embodiment of the present invention, the radius of the water-stirring member 200 refers to the distance from the farthest point from the rotation center to the rotation center on the horizontal cross section of the water-stirring member 200 .

[0106] Specifically, if the cross section of the agitating member 200 is circular, the radius is the radius R1 of the circular cross section. If the cross section of the agitating member 200 is non-circular, the radius is the distance R2 from the farthest point on the cross section to the rotation center.

[0107] In a further solution of this embodiment, the water-stirring member 200 at the maximum radius Rmax is also at a certain distance from the barrel mouth of the washing barrel 100 in the height direction, so that the washing water level can be higher than the water-stirring member 200 at the maximum radius Rmax, so that the clothes can be washed above the position of the water-stirring member 200 at the maximum radius Rmax.

[0108] In the above solution, the washing tub 100 can accommodate clothes for washing both above and below the water-stirring member 200 at the maximum radius Rmax. In this way, the outer surface of the water-stirring member 200 can basically contact the clothes to be washed, generating friction with the clothes, and the washing effect can be enhanced by increasing the surface area in contact with the clothes.

[0109] In this embodiment, the water-stirring component 200 includes a support column 210, which extends along the axial direction of the washing tub 100 and is coaxially arranged with the washing tub 100, and a water-stirring rib 220 arranged on the circumferential side of the support column 210 and extending along the axial direction of the support column 210. The lower end of the support column 210 is rotatably engaged with the bottom of the washing tub 100.

[0110] A mounting hole is provided at the center of the bottom of the washing tub 100, and the stirring shaft 300 for driving the water stirring member 200 to rotate is rotatably passed through the mounting hole. The lower end of the support column 210 is mounted on the upper end of the stirring shaft 300 and is connected to the stirring shaft 300 through a spline to achieve circumferential positioning; the support column 210 and the stirring shaft 300 are axially positioned by screws or a clamping structure.

[0111] The water stirring member 200 may be entirely disposed above the inner surface of the bottom of the washing tub 100 , or the lower end of the support column 210 of the water stirring member 200 may be at least partially inserted into the inner surface of the bottom of the washing tub 100 .

[0112] Preferably, the area of ​​the barrel bottom extending outward from the lower end of the support column 210 to the barrel wall is the washing surface 100-31, that is, when washing clothes, the area of ​​the barrel bottom extending outward from the lower end of the support column 210 to the barrel wall can contact the clothes in the barrel, that is, the clothes in the washing barrel 100 can reach the outer periphery of the lower end of the support column 210.

[0113] In this embodiment, by setting a water stirring member 200 to rotate with the bottom of the washing tub 100 through the support column 210, the bottom disc-shaped stirring portion 231 is eliminated, and the area of ​​the bottom of the tub extending outward from the lower end of the support column 210 to the tub wall is set as the washing surface 100-31, so that the clothes can come into contact and friction with the area of ​​the bottom of the tub extending outward from the lower end of the support column 210 to the tub wall, thereby avoiding the accumulation of dirt.

[0114] Preferably, in some possible embodiments, the water-stirring member 200 extends upward from the bottom of the washing tub 100. The lower end of the water-stirring member 200 is sleeved onto the upper end of the stirring shaft 300 and is no lower than the bottom surface of the tub around the mounting hole. The lower end of the water-stirring member 200 is radially flush or substantially flush with the sidewall of the stirring shaft 300. The area of ​​the bottom of the washing tub 100 extending outward from the mounting hole to the tub wall of the washing tub 100 is the washing surface 100-31.

[0115] Combined with the structure in which the lower end surface of the water-stirring component 200 almost does not exist, the bottom of the washing tub 100 is completely exposed to the washing water during washing, and the clothes can come into contact with all parts of the bottom of the tub, especially the area around the installation through hole, avoiding the existence of cleaning dead corners at the bottom of the tub where dirt and grime are easily hidden.

[0116] In this embodiment, the horizontal plane where the mounting through hole is located is flush with the washing surface 100 - 31 ; or, the washing surface 100 - 31 has a protruding surface on the periphery of the mounting through hole.

[0117] In other possible embodiments, a mounting groove 100-1 is provided on the upper surface of the bottom of the washing bucket 100, the lower end of the support column 210 is inserted into the mounting groove 100-1, the outer periphery of the lower end of the support column 210 is rotatably matched with the groove wall of the mounting groove 100-1, and the upper surface of the bottom of the outer periphery of the mounting groove 100-1 is the washing surface 100-31.

[0118] Preferably, a water seal structure 500 is provided between the outer periphery of the lower end of the support column 210 and the groove wall of the installation groove 100-1, and the upper end surface of the water seal structure 500 and the inner surface of the barrel bottom at the outer periphery of the water seal structure 500 constitute the washing surface 100-31.

[0119] In a specific solution of this embodiment, the washing surface 100-31 occupies 90% or more of the total area of ​​the bottom of the washing tub 100, preferably 95% or more of the total area of ​​the bottom of the washing tub 100100.

[0120] In this embodiment, the water stirring member 200 has a maximum radius along the radial direction of the washing tub 100 at a certain distance from the inner surface of the tub bottom, and a first guide surface 213 is formed on the lower side thereof, extending from the area close to the axis toward the periphery, for guiding the clothes below this area to move toward the periphery along the first guide surface 213 during washing; a second guide surface 214 is formed below the first guide surface 213, extending upward, for guiding the clothes to move along the second guide surface 214 toward the first guide surface 213 during washing.

[0121] Specifically, in this embodiment, the water stirring component 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water stirring rib 220 protruding from the side wall of the support column 210; clothes can be washed in the space formed by the bottom of the washing tub 100, the side wall of the support column 210 and the wall of the washing tub 100.

[0122] The support column 210 is arranged to change diameter axially below the maximum diameter of the water-stirring member 200, and includes a first extension section 211 and a second extension section 212 connected to each other; the side wall of the first extension section 211 extends upward from the bottom of the washing tub 100, and is used to guide the clothes to move toward the maximum diameter of the water-stirring member 200 during washing; the side wall of the second extension section 212 extends from the upper end of the first extension section 211 toward the periphery and tilts upward, extending to the height of the maximum diameter of the water-stirring member 200, and is used to guide the clothes below this point to move toward the periphery during washing.

[0123] The side wall of the first extending section 211 constitutes the second guiding surface 214 , and the side wall of the second extending section 212 constitutes the first guiding surface 213 .

[0124] Specifically, the water stirring member 200 provided in this embodiment is applied to a washing machine. During washing, the water stirring member 200 rotates relative to the washing tub 100, causing the clothes to move along the bottom of the washing tub 100 toward the center, then upward along the second guide surface 214 to the first guide surface 213. Guided by the first guide surface 213, they move toward the periphery and then fall near the wall of the washing tub 100, forming a circular path. This not only enhances the tumbling of the clothes within the tub, thereby improving the washing effect, but also reduces the probability of clothes converging toward the center and becoming tangled.

[0125] Preferably, in this embodiment, the water stirring rib 220 has a certain extension length along the axial direction of the washing tub 100 , extending from the second guide surface 214 to the first guide surface 213 .

[0126] In this embodiment, a plurality of water-stirring ribs 220 are arranged at circumferential intervals along the support column 210. The spacing angle between two adjacent water-stirring ribs 220 allows clothes to be washed in the spacing area between the two adjacent water-stirring ribs 220, avoiding dead corners where dirt is easily accumulated.

[0127] Preferably, the distance between the side of the agitating rib 220 away from the axis of the agitating member 200 and the axis of the agitating member 200 increases with increasing height.

[0128] The aforementioned structure of the agitating ribs 220 creates a Coanda effect during washing, driving water along the outer edges of the agitating ribs 220. This results in the water flowing along the outer edges of the agitating ribs 220 in the area near the axis of the washing tub 100. As the height increases, the water flows more upwards rather than outwards. This enhances the lifting force of the water flow on the clothes near the axis, driving the clothes upwards to the first guide surface 213, ultimately forming a circular path.

[0129] It can be understood that during washing, the clothes moving along the bottom of the barrel toward the central area can also be lifted along the outer edge of the water-stirring rib 220 after contacting the water-stirring rib 220. After moving to the maximum radius Rmax of the water-stirring part, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom of the barrel along the wall of the washing barrel 100.

[0130] In this embodiment, the washing water in the washing tub 100 rotates around the rotation center of the water stirring member 200 under the stirring of the water stirring member 200, moves toward the central area along the bottom of the washing tub 100, then moves upward along the second guide surface 214 to the first guide surface 213, moves toward the periphery under the guidance of the first guide surface 213, and then falls in an area close to the wall of the washing tub 100.

[0131] In the preferred solution of this embodiment, a smoothly transitioned rounded structure is provided at the connection position between the water stirring rib 220 and the support column 210, so that there are almost no cleaning dead corners on the water stirring component 200 where dirt is easily accumulated, thereby ensuring the cleanliness and hygiene inside the washing tub 100 to the greatest extent.

[0132] Further preferably, there is a rounded transition between the outer edge of the water-stirring rib 220 and the two side surfaces of the water-stirring rib 220 to avoid the existence of sharp corner structures that may scratch and damage clothes.

[0133] In this embodiment, by designing the specific structure of the water-stirring component 200, the side wall of the support column 210 is used to form a guiding surface that can guide the movement of clothes. Combined with the specific structure of the water-stirring rib 220, the effect of driving the clothes to move along a circular path below the maximum radius Rmax is better.

[0134] In an embodiment of the present invention, a control method for a washing device is further provided, wherein the washing device is equipped with the above-mentioned washing tub assembly. The control method for the washing device comprises:

[0135] During the drainage process of the washing tub 100, the water stirring member 200 rotates to speed up the drainage.

[0136] Preferably, in this embodiment, the washing machine detects the drainage speed during the drainage process. When the drainage speed slows, the water stirring member 200 is driven to rotate to agitate the clothes. Alternatively, when the washing machine detects that the drainage has timed out, the water stirring member 200 is driven to rotate to agitate the clothes. Alternatively, during the drainage process, the washing machine drives the water stirring member 200 to rotate intermittently or continuously to prevent clothes from clogging or blocking the drain outlet 100-32.

[0137] In this embodiment, the side of the water stirring member 200 is configured such that as the height of the rotation axis increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 remains constant or changes gradually or stepwise.

[0138] As a specific embodiment, the water-stirring member 200 has a single maximum radius point in the height direction. Furthermore, at least below the maximum radius point, as the height increases, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 decreases.

[0139] It should be noted that the single point with the largest radius may refer to the point with the largest radius of the water-stirring member 200 at a specific height position, or may refer to the point with the largest radius of the water-stirring member 200 within a certain continuous height range.

[0140] In the first specific solution, the point with the largest radius of the water-stirring member 200 is set at the top of the water-stirring member 200, that is, the top surface of the water-stirring member 200 is the cross-section with the largest radius.

[0141] In a second embodiment, the maximum radius of the agitating member 200 is close to the top of the agitating member 200, but is a certain distance away from the top of the agitating member 200. Specifically, the upper surface of the agitating member 200 at the maximum radius is an upwardly convex curved surface, and the highest point of the curved surface forms the top of the agitating member 200.

[0142] In the third specific solution, the largest radius of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0143] In one detailed embodiment, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 continuously changes in the height direction. Specifically, as the height increases, the diameter of the water stirring member 200 gradually increases from the bottom of the washing tub 100 upward until it reaches the maximum radius, after which the diameter of the water stirring member 200 gradually decreases until it reaches the top of the water stirring member 200.

[0144] In another detailed embodiment, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 changes abruptly at at least one height. Specifically, as the height increases, the diameter of the water-stirring member 200 gradually increases from the bottom of the washing tub 100 upwards. At a certain height, the diameter suddenly increases, forming the maximum radius. The diameter of the water-stirring member 200 then remains constant within a certain height range before suddenly decreasing, and then continues to gradually decrease, ultimately forming the top of the water-stirring member 200. In this embodiment, the distance from the maximum radius of the water-stirring member 200 to the bottom of the washing tub 100 refers to the distance from the lowest height within the height range where the diameter of the water-stirring member 200 remains constant to the bottom of the washing tub 100.

[0145] In another specific embodiment, the water-stirring member 200 has a plurality of maximum radii spaced apart along the axis of the washing tub 100. Specifically, as the height increases, the diameter of the water-stirring member 200 alternately increases and decreases, each time increasing to the same diameter and then decreasing, thereby forming a plurality of maximum radii spaced apart.

[0146] In a further embodiment of this embodiment, the maximum radius of the agitating member 200 is positioned at a height between the highest and lowest water levels of the washing machine. This allows the rotation of the agitating member 200 to generate different water flow patterns to move the laundry during washing at different water levels. In particular, as a specific embodiment, below the maximum radius of the agitating member 200, the laundry can be moved along a circular path during washing.

[0147] The circular path mentioned above means that the water moves toward the center of the bottom area of ​​the washing tub 100, is lifted by the water stirring member 200 to a position close to the maximum radius of the water stirring member 200, moves toward the periphery, and then falls.

[0148] As a specific solution, the circular path of the clothes moving below the maximum radius of the water-stirring member 200 during washing includes: the clothes move along the bottom of the washing tub 100 toward the central area, move upward along the side of the water-stirring member 200 in the central area to below the maximum radius and then move toward the periphery, and move downward in the area close to the wall of the washing tub 100.

[0149] In a further embodiment of the present invention, the water-stirring member 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water-stirring rib 220 protruding from the side wall of the support column 210. The direction of the water-stirring rib 220 and the protrusion on the side wall of the support column 210 coincide with the radial direction of the washing tub 100, or form an angle of less than 90° with the radial direction of the washing tub 100. In this way, when the water-stirring rib 220 rotates with the water-stirring member 200, the water-stirring rib 220 has a surface arranged opposite to the direction of rotation, which can achieve an effective stirring effect. The support column 210 is used to transmit the drive device connected to the washing equipment, so that the water-stirring member 200 can rotate under the drive of the drive device. The water-stirring rib 220 rotates in the washing tub 100 as the water-stirring member 200 does, stirring the clothes and water flow in the tub. The bottom of the washing tub 100, the side walls of the support column 210 and the walls of the washing tub 100 together form a space that can accommodate the laundry during washing, and the laundry can move along the above-mentioned annular path in the space.

[0150] The water-stirring member 200 has the above-mentioned structure, and the side surface of the water-stirring member 200 includes both the side wall of the support column 210 and the surface on the water-stirring rib 220 farthest from the rotation axis. The radius is the distance from the point on the water-stirring rib 220 farthest from the rotation axis to the center of rotation.

[0151] When the washing tub assembly of this embodiment is applied to a washing machine, in a specific implementation, when operating at a low water level lower than the maximum radius of the water stirring member 200, the clothes can move in the water along the circular path described above.

[0152] Specifically, during the washing process, relative rotation occurs between the water-stirring member 200 and the washing tub 100. The clothes move toward the central area along the bottom of the washing tub 100 in the space below the maximum radius of the water-stirring member 200 and gather in the space. In the central area, they are lifted to the bottom of the maximum radius along the side wall of the support column 210 or the outer edge of the water-stirring rib 220, and then move toward the periphery. After that, they fall to the bottom of the tub in the area close to the wall of the washing tub 100, forming a circular motion.

[0153] When operating at a high water level higher than the maximum radius of the water stirring member 200, the clothes move along the above-mentioned circular path in the water in the area below the maximum radius of the water stirring member 200; and in the area above the maximum radius of the water stirring member 200, the clothes move close to the circumferential direction of the washing tub 100.

[0154] Specifically, during the washing process, the agitating member 200 and the washing tub 100 rotate relative to each other. In the area below the maximum radius of the agitating member 200, the movement path of the clothes is essentially the same as that at low water levels. In the area above the maximum radius of the agitating member 200, the clothes move alternately forward and reverse along the circumference of the washing tub 100 as the agitating member 200 rotates alternately forward and reverse.

[0155] In the above solution, when using different wash water levels, the agitating member 200 can move the clothes in the tub in different ways for washing, providing more diverse washing options. Furthermore, in the area below the maximum radius of the agitating member 200, the clothes move in a circular path, which not only enhances the tumbling of the clothes and improves the washing effect, but also avoids the problem of clothes tending to gather in the center of the drum and causing entanglement in existing pulsator washing machines.

[0156] Regarding the solution in which the maximum radius of the agitating member 200 is located at or close to the top of the agitating member 200 , as a specific implementation, the maximum radius of the agitating member 200 is formed by the upper end of the outer peripheral edge of the agitating rib 220 .

[0157] Example 3

[0158] like Figures 5 to 8 As shown, an embodiment of the present invention describes a washing tub assembly for a washing machine. The washing tub assembly includes a washing tub 100 and a water agitation member 200 mounted on the washing tub 100. During operation, the washing tub 100 is rotated by the water agitation member 200, thereby washing the clothes in the washing tub 100.

[0159] In this embodiment, the washing tub 100 is a tub without holes.

[0160] In this embodiment, when the water-stirring member 200 is installed, a gap is formed between the bottom of the water-stirring member 200 and the bottom of the washing tub 100. During the washing process, dirt, lint, and other impurities on the clothes are easily accumulated in the gap between the bottom of the water-stirring member 200 and the bottom of the tub. The area within this gap does not come into contact with the clothes, so the impurities in the gap accumulate for a long time and cannot be effectively removed by simply flushing. This can easily breed bacteria and contaminate the clothes with the wash water.

[0161] In this embodiment, a water seal structure 500 is provided between the water stirring member 200 and the bottom of the washing tub 100. The water seal structure 500 is used to prevent washing water from entering the gap between the water stirring member 200 and the bottom of the washing tub 100, thereby preventing impurities such as dirt and lint that fall from the clothes from entering and accumulating in the gap between the water stirring member 200 and the bottom of the tub, thereby improving the cleanliness of the space in the washing tub 100 that is in contact with the washing water, thereby improving the cleaning effect on the clothes.

[0162] In this embodiment, the water-stirring member 200 extends axially along the washing tub 100, and the lower end of the water-stirring member 200 is plugged and rotatably engaged with the inner surface of the bottom of the washing tub 100. A water seal structure 500 is provided between the lower end circumference of the water-stirring member 200 and the center of the bottom of the washing tub where the clothes can reach.

[0163] In this embodiment, a water-stirring member 200 is provided to extend along the axial direction of the washing tub 100, and a water seal structure 500 is provided between the bottom of the tub where the clothes can reach, closest to its center, and the circumferential surface of the lower end of the water-stirring member 200. This allows the bottom of the washing tub 100 outside the water seal structure 500 to come into contact with the clothes, and the friction between the clothes and the inner surface of the bottom of the tub is used to prevent lint or other dirt from adhering to the inner surface of the bottom of the tub. At the same time, the water seal structure 500 can prevent the washing water from flushing the dirt to a position where the clothes cannot reach, effectively avoiding the problem of dirt easily accumulating between the water-stirring member 200 and the bottom of the tub and being difficult to clean, thereby improving the user experience.

[0164] In this embodiment, the water-stirring member 200 extends upward from the bottom of the washing tub 100, and includes a support column 210 and a water-stirring rib 220 arranged on the support column 210. The support column 210 extends along the axial direction of the washing tub 100, and the water-stirring rib 220 is arranged on the circumferential side of the support column 210 and extends along the length direction of the support column 210. The lower end of the support column 210 is rotatably engaged with the bottom of the washing tub 100.

[0165] An installation groove 100-1 is provided at the bottom of the barrel closest to the center where the clothes can reach. The lower end of the support column 210 is inserted into the installation groove 100-1, and the water seal structure 500 is provided between the groove wall of the installation groove 100-1 and the lower end circumference of the support column 210.

[0166] Specifically, in this embodiment, the stirring shaft 300 of the washing device coaxially extends into the washing tub 100 , the lower end of the support column 210 of the water stirring member 200 is connected to the upper end of the stirring shaft 300 , and the stirring shaft 300 is used to drive the water stirring member 200 to rotate.

[0167] The mounting groove 100-1 is arranged on the inner surface of the bottom of the washing bucket 100 and is coaxial with the washing bucket 100. The mounting groove 100-1 corresponds to the lower end of the support column 210. The lower end of the support column 210 is at least partially inserted into the mounting groove 100-1 and forms a rotating pair with the groove wall of the mounting groove 100-1. The water seal structure 500 is arranged between the groove wall of the mounting groove 100-1 and the circumferential surface of the lower end of the support column 210.

[0168] In this embodiment, the support column 210 extends along the axial direction of the washing tub 100, and the circumferential side of the support column 210 is arranged opposite to the barrel wall of the washing tub 100. The clothes in the washing tub 100 are arranged around the support column 210. During the rotation of the water-stirring member 200, the clothes can contact the circumferential side of the support column 210 and the barrel bottom of the washing tub 100 outside the support column 210. The friction between the clothes and the support column 210 and between the clothes and the part of the barrel bottom placed outside the support column 210 is used to prevent lint or other dirt from adhering to the circumferential side of the support column 210 and the barrel bottom outside the support column 210, effectively avoiding the problem that dirt and grime are easily hidden between the water-stirring member 200 and the barrel bottom and difficult to clean, thereby improving the user experience.

[0169] The water seal structure 500 is annular and is arranged between the groove wall of the installation groove 100-1 and the lower end circumference of the support column 210; the outer periphery of the water seal structure 500 is connected to the groove wall of the installation groove 100-1, and the inner periphery of the water seal structure 500 is elastically abutted against the lower end circumference of the support column 210.

[0170] In this embodiment, a connecting portion 215 is provided at the lower end of the support column 210, and the support column 210 is rotated to cooperate with the groove wall of the installation groove 100-1 through the connecting portion 215, and the water seal structure 500 is provided between the connecting portion 215 of the support column 210 and the inner wall of the installation groove 100-1.

[0171] A mounting groove is coaxially disposed at the opening of mounting groove 100-1. The mounting groove has a larger diameter than mounting groove 100-1. A water seal structure 500 is disposed within the mounting groove, with its lower end surface abutting against the bottom of the mounting groove and its upper end surface substantially flush with the inner surface of the barrel bottom. Preferably, the outer diameter of water seal structure 500 is greater than or equal to the inner diameter of the mounting groove, and the inner edge of water seal structure 500 elastically abuts against the lower circumferential surface of support column 210.

[0172] In this embodiment, the "upper end surface of the water seal structure 500 is basically flush with the inner surface of the barrel bottom" can specifically mean that the upper end surface of the water seal structure 500 is flush with the inner surface of the barrel bottom, or that the upper end surface of the water seal structure 500 protrudes from the inner surface of the barrel bottom, or that the upper end surface of the water seal structure 500 is slightly lower than the inner surface of the barrel bottom.

[0173] like Figures 6 to 8 As shown, in this embodiment, the water seal structure 500 includes a rubber body and a spring ring 500-5. The rubber body is arranged in the embedding groove and includes a rubber body body adapted to the embedding groove and a sealing lip 500-4 arranged between the inner periphery of the rubber body body and the lower end circumference of the support column 210 for elastic contact. The spring ring 500-5 is sleeved on the rubber body. By sleeved on the spring ring 500-5 on the rubber body, the sealing effect of the water seal structure 500 can be enhanced.

[0174] Preferably, in this embodiment, the spring ring 500 - 5 is hidden in the embedding groove, which can prevent the spring ring 500 - 5 from contacting with washing water, thereby preventing the spring ring 500 - 5 from rusting and improving the stability of the effect of the water seal structure 500 .

[0175] like Figure 6 and Figure 7 As shown, in some possible embodiments, the rubber body includes a rubber body main body and a sealing lip 500-4 disposed on the inner circumference of the rubber body main body. The rubber body main body includes a first extension portion 500-1 and a second extension portion 500-2, the first extension portion 500-1 and the second extension portion 500-2 being integrally formed. The first extension portion 500-1 extends upward from the bottom of the mounting groove along the groove wall of the mounting groove, the second extension portion 500-2 extends from the upper end of the first extension portion 500-1 toward the axis of the water-stirring member 200, and the sealing lip 500-4 extends from the inner circumference of the second extension portion 500-2 toward the support column 210. The water seal structure 500 abuts against the groove wall of the mounting groove through the first extension portion 500-1 and abuts against the lower end circumference of the support column 210 through the sealing lip 500-4.

[0176] In this embodiment, the first extension portion 500-1 extends axially along the water-stirring member 200. The outer diameter of the first extension portion 500-1 is greater than or equal to the wall of the mounting groove, and the inner diameter of the first extension portion 500-1 is greater than the inner diameter of the mounting groove 100-1. The second extension portion 500-2 extends in a direction substantially perpendicular to the direction of extension of the first extension portion 500-1. Specifically, the second extension portion 500-2 may extend horizontally along the radial direction of the water-stirring member 200, or may extend downwardly and tilted toward the axis of the water-stirring member 200, or may extend upwardly and tilted toward the axis of the water-stirring member 200.

[0177] Preferably, the second extending portion 500 - 2 extends along the radial direction of the water-stirring member 200 .

[0178] Preferably, in this embodiment, the thickness of the first extension portion 500-1 is substantially the same as the thickness of the second extension portion 500-2. The thickness of the first extension portion 500-1 is the difference between the outer radius and the inner radius of the first extension portion 500-1, and the thickness of the second extension portion 500-2 is the distance between the lower end surface and the upper end of the second extension portion 500-2.

[0179] In this embodiment, the sealing lip 500-4 is arranged on the inner periphery of the second extension portion 500-2 and extends from the inner periphery of the second extension portion 500-2 in a direction close to the axis of the water-stirring member 200. The end of the sealing lip 500-4 is elastically abutted against the circumferential surface of the lower end of the support column 210, and the sealing lip 500-4 has multiple circles arranged along the axial direction of the water-stirring member 200.

[0180] like Figure 7 As shown, in this embodiment, the sealing lip 500-4 located at the upper end of the inner circumference of the second extension portion 500-2 extends upwardly at an angle close to the axis of the water-stirring member 200, the sealing lip 500-4 located in the middle part of the inner circumference of the second extension portion 500-2 extends horizontally at an angle close to the axis of the water-stirring member 200, and the sealing lip 500-4 located at the lower end of the inner circumference of the second extension portion 500-2 extends downwardly at an angle close to the axis of the water-stirring member 200.

[0181] In this embodiment, the "sealing lip 500-4 located at the upper end of the inner circumference of the second extension portion 500-2", the "sealing lip 500-4 located in the middle of the inner circumference of the second extension portion 500-2", and the "sealing lip 500-4 located at the lower end of the inner circumference of the second extension portion 500-2" are respectively provided in at least one circle.

[0182] In this embodiment, the sealing lip 500-4 on the inner periphery of the second extension portion 500-2 can be provided in two circles, with the "sealing lip 500-4 located at the upper end of the inner periphery of the second extension portion 500-2", the "sealing lip 500-4 located in the middle part of the inner periphery of the second extension portion 500-2", and the "sealing lip 500-4 located at the lower end of the inner periphery of the second extension portion 500-2" being provided in one circle respectively.

[0183] Preferably, in this embodiment, the spring ring 500 - 5 is sleeved on the lowermost sealing lip 500 - 4 .

[0185] Preferably, in this embodiment, the curvature of the end portion of the sealing lip 500-4, which is located at the inner periphery of the second extension portion 500-2 and is located at the bottom, and which curves downward and away from the axis of the water-stirring member 200, is the same as the curvature of the cross-section of the spring coil 500-5. The end portion of the sealing lip 500-4, which is located at the inner periphery of the second extension portion 500-2 and is located at the bottom, covers the spring coil 500-5. Specifically, the end portion of the sealing lip 500-4, which is located at the inner periphery of the second extension portion 500-2 and is located at the bottom, covers at least the side of the spring coil 500-5 that is closest to the axis of the water-stirring member 200.

[0186] In this embodiment, the inner diameter of the spring ring 500-5 is smaller than or equal to the diameter of the lower end of the support column 210, thereby reinforcing the sealing lip 500-4 on the support column 210 and preventing the spring ring 500-5 from contacting the washing water.

[0187] Preferably, in this embodiment, the water seal structure 500 further includes a skeleton 500-3, which is located within the rubber body and extends in a direction substantially identical to that of the rubber body. The term "substantially identical" may mean that the skeleton 500-3 extends in the same direction as the rubber body, or that there is a slight deviation between the directions.

[0188] In this embodiment, the skeleton 500-3 and the rubber body are arranged in a coordinated manner. By embedding the skeleton 500-3 inside the rubber body, the shape and position of the first extension part 500-1 and the second extension part 500-2 of the rubber body can be shaped and supported, making the rubber body stronger.

[0189] Specifically, the skeleton 500 - 3 is made of a hard material, is injection-molded inside the rubber body, and is disposed in the middle of the first extension portion 500 - 1 and the second extension portion 500 - 2 .

[0190] Preferably, the skeleton 500-3 is disposed inside the rubber body, and both ends of the skeleton 500-3 extend from the corners of the first extension portion 500-1 and the second extension portion 500-2 toward the inside of the first extension portion 500-1 and the second extension portion 500-2 respectively.

[0191] like Figure 8As shown, in some other possible embodiments, the rubber body includes a rubber body main body and a sealing lip 500 - 4 arranged on the inner periphery of the rubber body main body.

[0192] In this embodiment, the shape of the rubber body is substantially the same as that of the embedding groove. The rubber body includes a first rubber segment 500-8 and a second rubber segment 500-9, the outer diameters of which gradually decrease from top to bottom. The first rubber segment 500-8 and the second rubber segment 500-9 are integrally formed.

[0193] The outer periphery of the first rubber segment 500-8 elastically abuts against the wall of the mounting groove, and / or the outer periphery of the first rubber segment 500-8 is bonded to the wall of the mounting groove, and the spring ring 500-5 is sleeved around the outer periphery of the second rubber segment 500-9. Thus, contact between the spring ring 500-5 and washing water can be prevented.

[0194] Preferably, in this embodiment, the lower end of the rubber body is in contact with the bottom of the mounting groove, and the upper end of the rubber body is basically flush with the inner surface of the barrel bottom. Preferably, the upper end surface of the rubber body is flush with the inner surface of the barrel bottom of the washing barrel 100.

[0195] Preferably, in this embodiment, an annular groove is provided on the outer periphery of the second rubber segment 500 - 9 , and the spring ring 500 - 5 is provided in the annular groove, thereby preventing the spring ring 500 - 5 from separating from the second rubber segment 500 - 9 .

[0196] And / or, the outer circumferential lower end of the second rubber segment 500-9 protrudes outward in a direction away from the water-stirring member 200 to limit the axial position of the spring ring 500-5 and prevent the spring ring 500-5 from separating from the second rubber segment 500-9.

[0197] In this embodiment, the sealing lip 500-4 includes a first sealing lip 500-6 and a second sealing lip 500-7. The first sealing lip 500-6 is arranged on the inner periphery of the first rubber segment 500-8, and the second sealing lip 500-7 is arranged on the inner periphery of the second rubber segment 500-9. The water seal structure 500 is elastically abutted against the outer periphery of the lower end of the support column 210 through the first sealing lip 500-6 and the second sealing lip 500-7.

[0198] Specifically, the first sealing lip 500-6 is arranged on the inner periphery of the first rubber segment 500-8, and extends upwardly and obliquely from the inner periphery of the first rubber segment 500-8 in a direction close to the axis of the water-stirring member 200; the first sealing lip 500-6 is provided with at least two circles, which are arranged at intervals along the axial direction of the first rubber segment 500-8.

[0199] Preferably, in this embodiment, the inner diameter of the first rubber segment 500-8 is greater than the inner diameter of the second rubber segment 500-9. A step is formed between the inner walls of the first rubber segment 500-8 and the second rubber segment 500-9. The first sealing lip 500-6 located at the bottom is arranged at the intersection of the inner circumferences of the first rubber segment 500-8 and the second rubber segment 500-9. The top of the first sealing lip 500-6 located at the top is flush with the upper end surface of the rubber body.

[0200] Specifically, in this embodiment, the first sealing lip 500-6 is provided with two circles, which are arranged along the axial direction of the first rubber segment 500-8. The top of the first sealing lip 500-6 located at the top is flush with the upper end surface of the rubber body, and the lower end surface of the first sealing lip 500-6 extends upward from the inner circumference of the first rubber segment 500-8 in a direction close to the axis of the water-stirring member 200. The thickness of the first sealing lip 500-6 located at the top gradually increases in a direction away from the axis of the water-stirring member 200.

[0201] The first sealing lip 500-6 located below extends upwardly and obliquely from the junction of the inner circumference of the first rubber segment 500-8 and the second rubber segment 500-9 in a direction close to the axis of the water-stirring member 200. The lower end of the root of the first sealing lip 500-6 located below is connected to the upper end of the inner circumference of the second rubber segment 500-9, and the upper end of the root of the first sealing lip 500-6 located below is connected to a position on the inner circumference of the first rubber segment 500-8 near its lower end. That is, the first sealing lip 500-6 located below extends upwardly and in a direction close to the axis of the water-stirring member 200 from the corner of the inner wall of the first rubber segment 500-8 and the inner wall of the second rubber segment 500-9.

[0202] Preferably, this embodiment further includes a third sealing lip 500-10, which is disposed between the two first sealing lips 500-6. Specifically, the root of the upper first sealing lip 500-6 is provided with a downwardly extending third sealing lip 500-10, with the end of the third sealing lip 500-10 abutting against the middle of the lower first sealing lip 500-6.

[0203] In this embodiment, the third sealing lip 500-10 extends vertically downward as a whole. The side of the third sealing lip 500-10 close to the axis of the water-stirring member 200 extends downward from the middle of the first sealing lip 500-6 located above in a direction away from the circumference of the water-stirring member 200, and the end of the third sealing lip 500-10 close to the axis of the water-stirring member 200 extends vertically downward. The side of the third sealing lip 500-10 away from the axis of the water-stirring member 200 extends downward from the root of the first sealing lip 500-6 located above in a direction close to the axis of the water-stirring member 200 and is inclined downward.

[0204] The end of the third sealing lip 500-10 corresponds to the middle of the first sealing lip 500-6 located below. Specifically, the end of the third sealing lip 500-10 corresponds to the position above the first sealing lip 500-6 located below and close to the root of the first sealing lip 500-6. The third sealing lip 500-10 and the first sealing lip 500-6 located below can be in contact or have a certain distance between them.

[0205] In this embodiment, the provision of the first sealing lip 500-6 can enhance the sealing effect of the first sealing lip 500-6. Specifically, the third sealing lip 500-10 can support the first sealing lip 500-6 located below, helping the first sealing lip 500-6 located below to rebound toward the axis of the water-stirring member 200, thereby improving the sealing effect.

[0206] In this embodiment, the axial cross-section of the first sealing lip 500 - 6 located at the bottom is a long rectangular strip.

[0207] In this embodiment, the second sealing lip 500-7 is provided on the inner periphery of the second rubber segment 500-9. The second sealing lip 500-7 is sawtooth-shaped. The axial cross section of the second sealing lip 500-7 is a triangle convex toward the axis of the water stirring member 200.

[0208] Preferably, the second sealing lip 500 - 7 is provided with at least two consecutive circumferences along the axial direction of the second rubber segment 500 - 9 .

[0210] In this embodiment, the middle portion of the lower end surface of the second sealing lip 500 - 7 located at the bottom abuts against the edge of the groove bottom of the embedding groove close to the axis of the water-stirring member 200 .

[0211] Further preferably, the upper end surface of the first rubber segment 500 - 8 is set to be a horizontal plane extending along the radial direction of the water-stirring member 200 .

[0212] Example 4

[0213] like Figure 9 and Figure 10As shown, this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly. In this embodiment, below the maximum radius of the water-stirring member 200, the distance between the side wall of the support column 210 and the tub wall of the washing tub 100 decreases as the height increases.

[0214] It should be noted that, in the embodiment of the present invention, the maximum radius of the water-stirring member 200 refers to the maximum radius of the horizontal cross-section of the water-stirring member 200, and the radius of the horizontal cross-section of the water-stirring member 200 refers to the distance from the farthest point from the center of rotation to the center of rotation on the horizontal cross-section of the water-stirring member 200 taken along the horizontal direction.

[0215] Specifically, if the horizontal cross-section of the agitating member 200 is circular, the radius is the radius R1 of the circular cross-section. If the horizontal cross-section of the agitating member 200 is non-circular, the radius is the distance R2 from the farthest point on the cross-section to the rotation center.

[0216] In this embodiment, a raised water-stirring rib 220 is provided on the sidewall of the support column 210. The radial dimension of the water-stirring rib 220 can remain constant as the height of the washing tub 100 increases, or it can change gradually or stepwise. Since the distance between the sidewall of the support column 210 and the wall of the washing tub 100 decreases as the height increases, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 decreases as the height increases.

[0217] In the above structure, the radius of any horizontal cross section of the water-stirring member 200 specifically refers to the distance from the farthest end of the water-stirring rib 220 from the axis to the central axis on the horizontal cross section.

[0218] In another embodiment, the agitating ribs extend spirally along the sidewall surrounding the support column. In this case, the horizontal cross-section of the agitating member 200 may not form a regular geometric shape, but the radius of the horizontal cross-section of the agitating member 200 is still the distance from the farthest end of the agitating ribs from the axis to the central axis in the cross-section.

[0219] In this embodiment, clothes can also be washed in the space formed by the bottom of the washing tub 100, the side walls of the support column 210 and the walls of the washing tub 100.

[0220] In a specific embodiment of this embodiment, the support column 210 includes a first extension section 211 and a second extension section 212, which are arranged below and connected to the maximum radius of the water-stirring member 200. The sidewalls of the first extension section 211 extend upward and tilt from the bottom of the washing tub 100, gradually approaching the tub wall of the washing tub 100. The sidewalls of the second extension section 212 extend from the upper end of the first extension section 211 toward the periphery and tilt upward to the height of the maximum radius of the water-stirring member 200. This allows laundry to be washed below the sidewalls of the second extension section 212 and move toward the periphery along the sidewalls of the second extension section 212.

[0221] More specifically, the sidewalls of the first extension section 211 extend in a straight line and are inclined outward at a slight angle relative to the vertical direction. The sidewalls of the second extension section 212 have a larger angle with the vertical direction than the sidewalls of the first extension section 211. Furthermore, as the height increases, the angle between the sidewalls of the second extension section 212 and the vertical direction gradually increases, forming a curved surface that bends toward the axis.

[0222] In this embodiment, the upper end of the support column 210 is also provided with a water stirring tray 230. Specifically, the upper end of the second extension section 212 is connected to the lower surface of the water stirring tray 230. The support column 210 of the water stirring member 200 has the above-described structure, which effectively reduces the problem of a cleaning dead angle between the upper end of the support column 210 and the lower surface of the water stirring tray 230, where clothes cannot reach.

[0223] In a detailed solution, the upper end of the side wall of the second extension section 212 coincides with the outer periphery of the water stirring tray 230 , so that the lower surface of the water stirring tray 230 is completely covered by the upper end surface of the support column 210 .

[0224] In the preferred embodiment of this embodiment, Figure 10 As shown, the upper surface of the water stirring tray 230 is a curved surface with a middle area higher than the outer area. A raised stirring portion 231 is provided on the curved surface. When the water level in the washing tub 100 is higher than the top of the water stirring tray 230, the stirring portion 231 rotates with the water stirring member 200 to stir the wash water above the water stirring tray 230 and rub the clothes above the water stirring tray 230, thereby enhancing the washing effect.

[0225] Furthermore, in this embodiment, the sidewall of the second extension section 212 forms a first guide surface 213 for guiding the clothes below it to move toward the periphery along the first guide surface 213 during washing. The sidewall of the first extension section 211 forms a second guide surface 214 for guiding the clothes to rise along the second guide surface 214 to the first guide surface 213 during washing.

[0226] Specifically, during washing, the washing machine using the washing tub assembly described in this embodiment rotates the water agitating member 200 relative to the washing tub 100, causing the laundry to move along the bottom of the washing tub 100 toward the center, then upward along the first guide surface 213 to the second guide surface 214. Guided by the second guide surface 214, the laundry moves toward the periphery before falling near the wall of the washing tub 100, forming a circular path. This enhances the tumbling of the laundry within the tub, thereby improving the washing effect, while also reducing the likelihood of the laundry converging toward the center and becoming tangled.

[0227] As a specific implementation of this embodiment, at the connecting position of the first extension section 211 and the second extension section 212, the angle between the side walls of the two and the vertical direction is the same. In other words, the first guide surface 213 and the second guide surface 214 have the same inclination angle at the connecting position, achieving a smooth transition connection.

[0228] In another specific embodiment, the inclination angle of the sidewall of the second extension section 212 at the lower end relative to the vertical direction is slightly higher than the inclination angle of the sidewall of the first extension section 211 relative to the vertical direction, thereby forming an angle less than but close to 180° at the junction of the first guide surface 213 and the second guide surface 214. This provides a certain cushioning effect on the clothing as it moves upward along the second guide surface 214 to the first guide surface 213, enhancing the tendency of the clothing to roll toward the periphery.

[0229] In a further embodiment of this embodiment, the agitating ribs 220 extend a certain length along the axial direction of the washing tub 100, extending from the sidewall of the first extension section 211 to the sidewall of the second extension section 212. A plurality of agitating ribs 220 are spaced apart circumferentially around the support column 210, and the angle between adjacent agitating ribs 220 allows laundry to be washed in the area between the adjacent agitating ribs 220 while allowing the laundry to contact the sidewall of the first extension section 211, thereby moving upward along the sidewall of the first extension section 211, i.e., the second guide surface 214.

[0230] In this way, the area of ​​the side walls of the first extension section 211 and the second extension section 212 located between two adjacent water-stirring ribs 220 can come into contact with the clothes, and no dead corner where dirt is easily accumulated is generated.

[0231] Furthermore, in this embodiment, the radial dimension of the water-stirring rib 220 along the washing tub 100 first increases and then decreases from the lower end to the upper end.

[0232] In one specific embodiment, the cross-section of the water-stirring rib 220 parallel to the radial direction of the washing tub 100 is approximately fusiform. The outer edge of the water-stirring rib 220 extends from bottom to top, and the angle between the extension direction and the vertical direction gradually decreases, so that the outer edge of the water-stirring member 200 forms a curve that bends toward the wall of the washing tub 100. The upper end of the outer edge of the water-stirring rib 220 coincides with the outer periphery of the water-stirring tray 230.

[0233] The aforementioned structure of the agitating ribs 220 creates a Coanda effect during washing, driving water along the outer edges of the agitating ribs 220. This results in the water flowing along the outer edges of the agitating ribs 220 in the area near the axis of the washing tub 100. As the height increases, the water flows more upwards rather than outwards. This enhances the lifting force of the water flow on the clothes near the axis, driving the clothes upwards to the first guide surface 213, ultimately forming a circular path.

[0234] It can be understood that the clothes moving along the bottom of the barrel toward the central area can also be lifted along the outer edge of the water-stirring rib 220 after contacting the water-stirring rib 220. After moving to the maximum radius of the water-stirring component 200, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom of the barrel along the wall of the washing barrel 100.

[0235] In a preferred embodiment of this embodiment, the agitating member 200 is installed in the washing tub 100. A certain distance exists between the lower end of the agitating rib 220 and the bottom of the washing tub 100 to avoid any blind spots between the agitating rib 220 and the bottom. Specifically, the lower end of the support column 210 includes a connecting portion 215 that is rotatably inserted into the mounting groove 100-1 on the tub bottom. The lower end of the agitating rib 220 is at least flush with, and preferably higher than, the upper end of the connecting portion 215. The agitating shaft, which drives the agitating member 200, is inserted from its lower end into the connecting portion 215 and secured thereto.

[0236] More preferably, a smoothly transitioned rounded structure is provided at the connection position between the water stirring rib 220 and the support column 210, so that there are almost no cleaning dead corners on the water stirring component 200 where dirt is easily accumulated, thereby ensuring the cleanliness and hygiene inside the washing tub 100 to the greatest extent.

[0237] Further preferably, there is a rounded transition between the outer edge of the water-stirring rib 220 and the two side surfaces of the water-stirring rib 220 to avoid the existence of sharp corner structures that may scratch and damage clothes.

[0238] It is understood that the connection portion at the lower end of the support column can also be completely located inside the washing tub, with the agitator shaft inserted into the connection portion through the mounting groove 100-1 on the washing tub bottom. By setting a certain distance between the lower end surface of the connection portion and the washing tub bottom, or by setting the difference between the outer diameter and the inner diameter of the connection portion to be sufficiently small, the outer surface of the connection portion (including the outer wall and any lower end surface) and the area of ​​the washing tub bottom located outside the mounting groove 100-1 can contact the clothes, thereby preventing the formation of blind spots during cleaning.

[0239] As a specific embodiment, the thickness of the water-stirring rib 220 in the circumferential direction gradually decreases radially outward, and along the axial direction, the thickness of the middle area of ​​the water-stirring rib 220 is greater than the thickness at the upper and lower ends.

[0240] In this embodiment, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 varies due to the varying cross-sectional dimensions of the support column 210 itself. This also creates a structure where the point of maximum radius is a certain distance from the bottom of the washing tub 100, ensuring that clothes can be washed below the point of maximum radius of the water-stirring member 200. Furthermore, the sidewalls of the support column 210 form a first guide surface 213 and a second guide surface 214 that guide the movement of clothes during washing. This effectively drives clothes to move and turn along a circular path below the point of maximum radius of the water-stirring member 200, resulting in better washing results and preventing clothes from becoming entangled.

[0242] like Figure 11 As shown, in this embodiment, the water-stirring member 200 includes an assembly portion 210-1 and a water-stirring portion 240 extending upward from the assembly portion 210-1. The assembly portion 210-1 is configured as a solid structure, and the water-stirring portion 240 is at least partially configured as a hollow structure. For example, the water-stirring portion 240 is a cavity configured axially from the top end toward the assembly portion 210-1.

[0243] Specifically, in this embodiment, the assembly portion 210-1 is a solid cylinder, which can increase the connection strength of the water-stirring member 200. The water-stirring portion 240 has an integrally formed hollow structure, which is formed on the top of the assembly portion 210-1. The assembly portion 210-1 can also block the lower end of the hollow structure of the water-stirring portion 240.

[0244] As a specific embodiment, the water-stirring member 200 includes a support column 210, and a water-stirring rib 220 arranged on the side wall of the support column 210, protruding along the radial direction or near radial direction of the support column away from the axis of the support column 210. The water-stirring rib 220 extends along the axial direction of the support column in the length direction, and extends in the width direction away from the circumference of the support column. It can be arranged radially or deviate from the radial direction.

[0245] In this embodiment, the support column 210 includes an assembly portion 210-1 and a hollow column 210-8 coaxially connected to the upper portion of the assembly portion 210-1. The assembly portion 210-1 is a solid column, preferably a circular cylinder, and the hollow column 210-8 extends upward from the upper end surface of the assembly portion 210-1. The outer diameter of the hollow column 210-8 at the connection between the assembly portion 210-1 and the assembly portion 210-1 can be greater than the diameter of the assembly portion 210-1, or less than or equal to the diameter of the assembly portion 210-1. The outer wall of the hollow column 210-8 smoothly transitions upward with the outer wall of the assembly portion 210-1.

[0246] The water-stirring portion 240 has a horizontal cross-section with its maximum radius at a predetermined height from the upper end of the assembly portion 210-1. A water-stirring disc 230 is disposed at the top of the support column 210. The maximum radius Rmax of the water-stirring portion 240 is defined by the outer periphery of the water-stirring disc 230, whose top surface is an upwardly convex curved surface. A cavity 210-9 is formed within the hollow column 210-8, similar in shape to the outer shape of the support column 210.

[0247] Preferably, the water stirring rib 220 is also configured as a hollow structure.

[0248] Further preferably, the internal space of the water stirring rib 220 is connected to the cavity 210-9 inside the hollow column 210-8.

[0250] In this embodiment, the water stirring portion 240 is connected to the stirring shaft 300 rotatably passing through the bottom of the washing tub 100 through the assembly portion 210 - 1 , so that the water stirring member 200 can rotate relative to the washing tub 100 .

[0251] Specifically, the assembly portion 210 - 1 and the stirring shaft 300 are circumferentially positioned by splines and rotate together, and are axially positioned by screws 210 - 7 .

[0252] In this embodiment, the assembly portion 210-1 is provided with a spline groove 210-6 extending coaxially upward from the lower end surface of the assembly portion 210-1. The spline groove 210-6 is at least partially sleeved on the upper end portion of the agitator shaft 300 and is keyed to the agitator shaft 300. The spline groove 210-6 is formed on the assembly portion 210-1 of the water-stirring member 200.

[0253] In this embodiment, the top of the agitating member 200 is provided with an opening that communicates with the cavity 210-9 within the hollow column. A screw 210-7 passes through the opening and enters the cavity 210-9, downwardly engaging the agitating shaft 300 keyed to the assembly portion 210-1, thereby axially securing the agitating member 200 to the agitating shaft 300. To prevent water from entering the cavity 210-9, a sealing member is installed at the opening.

[0254] Preferably, a sealing groove 210-4 is provided on the top of the water stirring member 200. The sealing groove 210-4 is formed by being coaxially recessed downward from the top surface of the water stirring plate 230. An opening communicating with the mold cavity 210-9 is provided at the bottom of the sealing groove 210-4.

[0255] Specifically, the upper end of the assembly portion 210-1 is provided with a through-hole, preferably a threaded hole. The shaft of a screw 210-7 passes through the top of the assembly portion 210-1 and is tightened in the threaded hole, with the head of the screw 210-7 abutting the top of the assembly portion 210-1. Operators remove and install the screw 210-7 through the opening at the bottom of the sealing groove 210-4 and the cavity 210-9 of the hollow column 210-8. The screw is preferably a countersunk screw.

[0256] The sealing groove 210 - 4 is provided with a sealing cover 210 - 5 for sealing the upper end of the water-stirring member 200 to prevent washing water from entering the interior of the water-stirring member 200 .

[0257] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion. The flat plate portion covers the notch of the sealing groove 210-4 and is embedded in the top of the water-stirring component 200.

[0258] The top of the flat plate portion and the top of the water-stirring member 200 are in the same plane.

[0259] The sealing groove 210-4 includes a first section and a second section with increasing diameter from top to bottom. The lower end of the plug-in part is provided with a limiting protrusion protruding from the outer wall of the lower end of the plug-in part in the direction away from the axis of the water-stirring component 200. The limiting protrusion is engaged at the junction between the first section and the second end.

[0260] Preferably, the inner wall of the first section and the inner wall of the second section of the sealing groove 210-4 are transitionally connected by a tapered surface that tilts downward from top to bottom away from the axis of the water-stirring member 200. The shape of the limiting protrusion matches the shape between the first and second sections of the sealing groove 210-4. The outer circumferential surface of the limiting protrusion fits with the inner wall of the second section, and the top of the limiting protrusion fits with the tapered surface between the first and second sections of the limiting groove. Preferably, the bottom of the limiting protrusion is configured as a tapered surface with a gradually decreasing outer diameter from top to bottom, and the outer diameter of the bottom of the limiting protrusion is smaller than the inner diameter of the notch of the sealing groove 210-4.

[0261] In this embodiment, a sealing ridge extending circumferentially along the central portion of the plug-in portion is provided, and the plug-in portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 via the sealing ridge. Preferably, the sealing ridge extends circumferentially along the plug-in portion and is provided with multiple circles spaced apart along the axial direction of the plug-in portion.

[0262] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring member 200 to improve the smoothness of the insertion of the sealing cover 210 - 5 .
