[0002] As a convenient clothes washing device, washing machines have been widely used in people's lives. Existing washing machines are divided into drum washing machines and pulsator washing machines. Among them, pulsator washing machines are popular among users because of their better cleaning effect.

[0003] A pulsator washing machine typically includes a washing tub and a pulsator, which is located at the bottom of the tub. During operation, the rotation of the pulsator drives the washing water in the tub, washing the laundry inside. Existing pulsators are typically flat, circular pulsators. During washing, impurities such as dirt and lint from clothing 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, creating a negative user experience.

[0004] Chinese invention patent application number CN201910681427.5 discloses a washing machine comprising a pulsator and a washing tub, with a sealing structure disposed between the pulsator and the washing tub for sealing the area between the pulsator and the washing tub. In the above solution, the sealing structure is disposed between the annular rib and the stepped portion. Washing water can still enter the gap between the pulsator and the peripheral wall, forming dirt between the pulsator and the bottom of the washing tub, posing a risk of secondary contamination of laundry. Furthermore, the pulsator of this structure has a large sealing structure, which can easily cause significant damping to the pulsator's rotation. Furthermore, the sealing structure is extremely susceptible to damage.

[0005] Therefore, designing a washing device that can avoid dirt from being generated between the water stirring component and the bottom of the washing tub has become a technical problem that needs to be solved urgently by those skilled in the art.

[0006] Chinese utility model patent application number CN201520398758.5 ​​discloses a pulsator washing machine, belonging to the field of electrical appliances, and addressing the technical problem of insufficient cleaning capacity in existing washing machines. The utility model provides a pulsator washing machine comprising a body, a water storage tub, and a washing and dehydrating tub. A rotatable pulsator disc is provided at the bottom of the washing and dehydrating tub, and an intermediate column is provided on the pulsator disc, which is coaxial with the pulsator disc. The intermediate column is provided with a detergent inlet and a detergent outlet, and the detergent inlet and the detergent outlet are connected. The detergent outlet communicates with the washing space above the pulsator disc. In the above solution, the intermediate column is provided on the pulsator disc, and dirt easily accumulates between the pulsator disc and the bottom of the washing and dehydrating tub, making it difficult to clean.

[0007] Therefore, designing a washing tub assembly of a washing device that can avoid dirt accumulation between the water stirring member and the bottom of the washing tub has become a technical problem that needs to be solved urgently by those skilled in the art.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] As shown in Figures 1 to 28, an embodiment of the present invention describes a washing machine comprising a washing tub assembly, wherein the washing tub assembly comprises a washing tub 100 and a water stirring member 200 mounted on the washing tub 100. When the washing machine is in operation, the washing water in the washing tub 100 rotates through the rotation of the water stirring member 200, thereby washing the clothes in the washing tub 100.

[0058] The washing machine also includes a drive device in driving connection with the washing tub 100 and the water-stirring member 200. Specifically, the output shaft of the drive device is respectively in driving connection with the stirring shaft 300 and the dehydrating shaft. The stirring shaft 300 is connected to and fixed relative to the water-stirring member 200, driving the water-stirring member 200 to rotate. The dehydrating shaft is fixed to the bottom of the washing tub 100, driving the washing tub 100 to rotate.

[0059] The water stirring member 200 of the existing washing equipment is usually a flat circular impeller. The water stirring part of the water stirring member 200 is generally a bottom disc-shaped stirring part, that is, the impeller disc. When washing, impurities such as lint on the clothes fall off and are easily accumulated in the gap between the bottom surface of the impeller and the washing tub 100.

[0060] In this embodiment, the water-stirring component 200 includes an assembly portion 210-1 and a water-stirring portion arranged on the top of the assembly portion 210-1. The assembly portion 210-1 is arranged above the inner surface of the barrel bottom, or the assembly portion 210-1 at least partially extends to the inner surface of the barrel bottom of the washing barrel 100, and the water-stirring portion extends upward from the top of the assembly portion 210-1; the part of the assembly portion 210-1 located between the water-stirring portion and the barrel bottom can contact the clothes in the washing barrel 100.

[0061] Specifically, in this embodiment, a mounting through hole cooperating with the stirring shaft 300 is provided on the bottom of the washing tub 100 , and the stirring shaft 300 extends from the mounting through hole to the inside of the washing tub 100 , and the stirring shaft 300 and the washing tub 100 are coaxially arranged.

[0062] The water stirring member 200 is assembled with the stirring shaft 300 via the assembly portion 210 - 1 .

[0063] In this embodiment, the assembly portion of the water-stirring component is sleeved on the upper end of the stirring shaft, and the assembly portion and the stirring shaft are key-connected. The assembly portion and the stirring shaft are circumferentially positioned by splines. Preferably, the assembly portion of the water-stirring component and the stirring shaft are axially positioned by a clamping structure or screws.

[0064] Example 1

[0065] As shown in FIG. 1 to FIG. 4 , in this embodiment, the washing tub 100 is a tub without holes.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] The water seal structure divides the inner wall of the bottom of the washing tub into two areas, including a first area and a second area. The first area is close to the center of the bottom of the washing tub and is blocked by the water seal structure. The water seal structure can prevent water and clothes from entering the first area; the second area is the space inside the washing tub except the first area and can come into contact with washing water and clothes.

[0073] Specifically, in this embodiment, the area below the water seal structure and the area within the water seal structure are the first area, and the area above the water seal structure and the area outside the water seal structure are the second area. That is, the first area includes the gap between the groove wall of the installation groove 100-1 and the bottom peripheral surface of the water-stirring member, and the gap between the groove bottom of the installation groove and the bottom end surface of the water-stirring member.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] As shown in Figures 2 to 4 , in this embodiment, the water seal structure 500 includes a rubber body and a spring ring 500-5. The rubber body is positioned within the mounting groove and includes a rubber body body adapted to fit within the mounting groove, and a sealing lip 500-4 elastically abutting between the inner periphery of the rubber body body and the lower end surface of the support column 210. The spring ring 500-5 is sleeved onto the rubber body. Sleeving the spring ring 500-5 onto the rubber body enhances the sealing effect of the water seal structure 500.

[0082] 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 .

[0083] As shown in Figures 2 and 3, in some possible embodiments, the rubber body includes a main body and a sealing lip 500-4 disposed on the inner periphery of the main body. The main body includes a first extension portion 500-1 and a second extension portion 500-2, which are integrally formed. The first extension portion 500-1 extends upward from the bottom of the mounting groove along the groove wall, and 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. The sealing lip 500-4 extends from the inner periphery of the second extension portion 500-2 toward the support column 210. The water seal structure 500 abuts the groove wall of the mounting groove through the first extension portion 500-1 and abuts the lower end circumference of the support column 210 through the sealing lip 500-4.

[0084] Specifically, in this embodiment, the area below the second extension part 500-2 and the inner periphery of the first extension part 500-1 is the shielded first area, and the area above the second extension part 500-2 and the outer periphery of the first extension part 500-1 are the second area that can come into contact with water and clothing.

[0085] 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.

[0087] 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.

[0088] 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.

[0089] As shown in Figure 3, 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 upward at an angle close to the axis of the water-stirring member 200, the sealing lip 500-4 located in the middle 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 downward at an angle close to the axis of the water-stirring member 200.

[0092] Preferably, in this embodiment, the spring ring 500 - 5 is sleeved on the lowermost sealing lip 500 - 4 .

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 .

[0099] 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.

[0100] As shown in FIG. 4 , in some other possible embodiments, the rubber body includes a rubber body main body and a sealing lip 500 - 4 provided on the inner periphery of the rubber body main body.

[0101] 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.

Thus, contact between the spring ring 500-5 and washing water can be prevented.

[0103] 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.

[0104] 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 .

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] In this embodiment, the axial cross-section of the first sealing lip 500 - 6 located at the bottom is a long rectangular strip.

[0116] 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.

[0117] 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 .

[0118] Preferably, in this embodiment, the lower end surface of the second rubber segment 500-9 is set as an inclined surface inclined downward in the direction close to the axis of the water-stirring member 200, and the lower end of the second rubber segment 500-9 abuts against the bottom of the embedding groove through the inclined surface inclined downward in the direction close to the axis of the water-stirring member 200.

[0119] 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 .

[0120] 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 .

[0121] Example 2

[0122] As shown in Figures 5 to 10, in this embodiment, the washing tub 100 may include an inner tub and an outer tub coaxially sleeved outside the inner tub. When washing clothes, there may be water or no water between the inner tub and the outer tub, and the water stirring member 200 is arranged on the inner side of the bottom of the inner tub.

[0123] Alternatively, the washing tub 100 may be a tub without holes, and the washing tub 100 is used for containing both clothes and washing water.

[0124] In this embodiment, the mounting portion 210-1 corresponds to the mounting hole in the middle of the bottom of the tub, and its diameter is greater than the diameter of the agitator shaft. Preferably, the inner surface of the bottom of the washing tub 100 is provided with a mounting groove 100-1. The lower end of the mounting portion 210-1 is provided with a connecting portion 215 that is rotatably inserted into the mounting groove 100-1. The radial dimension of the connecting portion 215 is greater than or equal to the radial dimension of the portion of the mounting portion 210-1 between the connecting portion 215 and the water stirring portion, and is less than the radial dimension of any horizontal cross-section of the water stirring portion.

[0125] In this embodiment, the mounting groove 100-1 is disposed around the agitator shaft 300, and the mounting through-hole is provided at the bottom of the mounting groove 100-1. The agitator shaft passes through the mounting groove 100-1 and extends into the interior of the washing tub 100. The assembly portion of the agitator member is sleeved onto the agitator shaft 300. The diameter of the connecting portion 215 at the bottom of the assembly portion 210-1 matches the diameter of the mounting groove 100-1, and a revolute pair is formed between the outer edge of the connecting portion 215 and the wall of the mounting groove 100-1.

[0126] The connecting portion 215 is cylindrical, and the assembly portion 210-1 between the connecting portion 215 and the water stirring portion is columnar. It can be a columnar shape with a diameter gradually increasing from top to bottom, a columnar shape with a diameter gradually decreasing from top to bottom, a cylindrical shape, or a prismatic shape. It is only necessary to ensure that the clothes in the washing tub can contact the part of the assembly portion placed between the connecting portion and the water stirring component.

[0127] In this embodiment, even though the gap between the agitating member 200 and the bottom of the drum is extremely small, there's still a certain amount of potential for dirt to accumulate. Because the gap is relatively narrow and inconvenient for users to access, they typically need to remove the impeller to clean the dirt within. Existing washing machines typically attach the agitating member 200 to the agitator shaft 300 via screws 210-7, making it difficult for users to remove and assemble the agitating member 200.

[0128] In this embodiment, an installation structure of a water-stirring component 200 is also introduced. The installation structure is suitable for a water-stirring component 200 with a large axial length. The glue component with a large axial length can specifically be a stirring column, a stirring rod, a stirring rod, etc.

[0129] As shown in FIG. 5 , in this embodiment, the mounting structure is provided between the assembly portion 210 - 1 and the stirring shaft 300 of the washing device, for achieving axial positioning between the water stirring member 200 and the stirring shaft 300 .

[0130] As shown in Figure 6, the installation structure includes an insert 401 arranged at the end of the stirring shaft 300 and a locking assembly arranged in the assembly part 210-1 of the water-stirring member 200. When the water-stirring member 200 is installed, the insert 401 is at least partially inserted into the assembly part 210-1, and the locking assembly in the assembly part 210-1 locks the insert 401 along the axial direction of the water-stirring member 200, thereby realizing axial positioning between the water-stirring member 200 and the stirring shaft 300.

[0131] Specifically, the locking assembly includes a positioning cavity 402 and a stopper 403, which are coaxially arranged. The assembly portion 210-1 is provided with an installation cavity 210-2, and the positioning cavity 402 and the stopper 403 are arranged in the installation cavity 210-2.

[0132] The positioning cavity 402, the limiting member 403, and the insert 401 are coaxially arranged. When the water-stirring member 200 is installed, the insert 401 is inserted into the installation cavity 210-2 from the bottom of the assembly portion 210-1 and into the limiting member 403. The positioning cavity 402 and the limiting member 403 are close to each other, which can lock the insert 401. The positioning cavity 402 and the limiting member 403 are far away from each other, which can unlock the insert 401.

[0133] In this embodiment, the insert 401 is cylindrical and can be coaxially arranged on the upper end of the stirring shaft 300 by any feasible means such as welding, bonding, molding, and threaded connection. A limiting groove is provided on the insert 401, and the limiting groove is arranged around the peripheral wall of the insert 401; the limiting member 403 includes a limiting cavity 4031 and a clamping member 4032, and a limiting hole 4033 is provided on the side wall of the limiting cavity 4031. The clamping member 4032 can enter and exit the limiting groove in the radial direction of the insert 401, and the limiting hole 4033 is used to limit the entry and exit path of the clamping member 4032 in the radial direction of the insert 401; the limiting member 403 is at least partially inserted into the positioning cavity 402, and the diameter of the positioning cavity 402 gradually increases in the direction of the limit member 403 coming out, and the inner wall of the positioning cavity 402 confines the clamping member 4032 in the limiting groove.

[0134] In this embodiment, the positioning cavity 402 and the limiting member 403 tend to approach each other. When the stirring assembly is installed, the insert 401 is inserted into the installation cavity 210-2 from the bottom of the assembly portion 210-1. During the insertion of the insert 401 into the locking assembly, the insert 401 first squeezes the limiting member 403, separating the positioning cavity 402 from the limiting member 403. Under the action of the insert 401, the clamping member 4032 moves along the limiting hole 4033 in a direction away from the axis of the water stirring member 200. The clamping member 4032 will not completely disengage from the limiting hole 4033 due to the stopping action of the positioning cavity 402. At this time, the insert 401 can enter the limiting cavity 4031. When the clamping member 4032 corresponds to the limiting groove, the clamping member 4032 enters the limiting groove, and the limiting member 403 and the positioning cavity 402 move closer to each other. Due to the effect of the gradually decreasing diameter of the positioning cavity 402, the clamping member 4032 enters the limiting member 403 from the limiting hole 4033 and is stuck in the limiting groove of the insert 401, thereby clamping the insert 401, thereby positioning the water stirring member 200 from the axial direction of the stirring shaft 300.

[0135] Preferably, in this embodiment, the inner wall of the positioning cavity 402 is configured as a frustum that is inclined in a direction away from the axis of the water-stirring member 200 along the direction in which the limiting member 403 escapes.

[0136] Preferably, in this embodiment, the limiting groove extends along the circumference of the insert 401, and the limiting groove is configured to gradually increase in depth along the direction in which the limiting member 403 is inserted into the positioning cavity 402. After the water-stirring member 200 is installed, the clamping member 4032 abuts against the middle portion of the bottom of the limiting groove to ensure that the clamping member 4032 locks the insert 401 and prevents axial shaking of the water-stirring member 200 during operation.

[0137] Preferably, as shown in Figure 7, in this embodiment, the limiting cavity 4031 is configured as a column with an isosceles trapezoidal axial cross-section, and the side wall of the limiting cavity 4031 is configured as a frustum with a diameter gradually increasing in the direction of escaping the positioning cavity 402. The inclination angle of the side wall of the limiting cavity 4031 in the direction of escaping the positioning cavity 402 toward the direction away from the axis of the water-stirring component 200 is less than or equal to the inclination angle of the inner wall of the positioning cavity 402 in the direction of escaping the limiting member 403 toward the direction away from the axis of the water-stirring component 200.

[0138] Preferably, as shown in Figures 7 to 9, the limiting holes 4033 are provided with a plurality of them evenly arranged along the circumference of the limiting cavity 4031, and each of the limiting holes 4033 is provided with a clamping member 4032, and the clamping member 4032 is set to a spherical shape that matches the shape of the limiting hole 4033.

[0139] Preferably, three limiting holes 4033 are provided.

[0140] The bottom of the assembly portion 210-1 is provided with a through hole communicating with the installation cavity 210-2, and the through hole is adapted to fit the insert 401. Preferably, the diameter of the lower end of the through hole gradually increases from top to bottom, so as to improve the smoothness of the insertion of the insert 401.

[0141] The top of the insert 401 is preferably designed as a round head, and the clamping member 4032 is also preferably designed as a spherical ball, so that when the insert 401 is pushed into the limiting member 403, when the radial cross-section of the positioning cavity 402 becomes larger, the clamping member 4032 can more easily fall into the limiting groove of the insert 401.

[0142] In this embodiment, there is a tendency for the positioning cavity 402 and the limiting member 403 to approach each other to lock the insert 401, and an unlocking component is also provided between the outer periphery of the positioning cavity 402 or the limiting member 403 and the side wall of the assembly part 210-1 for driving the limiting cavity 4031 and the limiting member 403 to separate from each other to unlock the insert 401.

[0143] The unlocking assembly is arranged at the portion of the assembly portion 210 - 1 between the water stirring portion and the inner surface of the barrel bottom, which makes it easy for the user to operate the unlocking assembly.

[0144] Specifically, in this embodiment, one of the positioning cavity 402 and the limiting member 403 is fixed to the assembly portion 210 - 1 , and the other can slide along the axial direction of the water-stirring member 200 .

[0145] In some possible embodiments, the limit member 403 is coaxially fixed on the bottom inner wall of the installation cavity 210-2, the positioning cavity 402 is coaxially arranged above the limit member 403, the opening of the positioning cavity 402 faces downward, and the diameter of the positioning cavity 402 gradually increases from top to bottom, and the unlocking component is used to drive the positioning cavity 402 to move axially.

[0146] The insert 401 is inserted into the installation cavity 210-2 from the bottom of the assembly portion 210-1, and the upper end of the insert 401 abuts against the clamping member 4032 in the limit member 403. At this time, the side of the clamping member 4032 close to the axis of the water-stirring member 200 abuts against the upper end of the insert 401, and the side of the clamping member 4032 away from the water-stirring member 200 abuts against the inner wall of the positioning cavity 402. Since the positioning cavity 402 tends to move toward the limit member 403, the insert 401 cannot continue to be inserted.

[0147] The user operates the unlocking component to move the positioning cavity 402 upward. Since the inner wall of the positioning cavity 402 gradually increases from top to bottom, as the positioning cavity 402 moves upward, the diameter of the inner wall at the point where the positioning cavity 402 and the clamping member 4032 abut against each other increases. The clamping member 4032 moves in a direction away from the axis of the water-stirring member 200 under the squeezing of the insert 401. At this time, the insert 401 can continue to be inserted.

[0148] As the insert 401 is inserted, when the clamping piece 4032 enters the limiting groove, the positioning cavity 402 moves downward, and the end of the clamping piece 4032 close to the axis of the water-stirring member 200 abuts against the bottom of the limiting groove, and the end of the clamping piece 4032 away from the axis of the water-stirring member 200 abuts against the inner wall of the positioning cavity 402, thereby realizing axial positioning of the insert 401.

[0149] In this embodiment, the unlocking assembly includes a driving portion 404 and a driven portion 405 . The driving portion 404 is disposed on the side wall of the assembly portion 210 - 1 , and the driven portion 405 is disposed on the positioning cavity 402 and cooperates with the driving portion 404 in transmission.

[0150] Specifically, the driven portion 405 includes a hollow limiting post 4051 disposed on the positioning cavity 402 and an extension plate 4052 extending radially from the outer wall of the hollow limiting post 4051 away from the axis of the water-stirring member 200. The hollow limiting post 4051 extends upward from the top of the positioning cavity 402 and is integrally connected to the positioning cavity 402. The inner diameter of the hollow limiting post 4051 matches the diameter of the insert 401. The extension plate 4052 abuts against the driving portion 404 via an inclined surface that tilts from top to bottom toward the axis of the water-stirring member 200. When the driving portion 404 moves toward the axis of the water-stirring member 200, the driving portion 404 presses the end of the extension plate 4052, pushing the positioning cavity 402 upward.

[0151] As shown in Figures 6 to 10, in other possible embodiments, the positioning cavity 402 is fixedly arranged on the bottom inner wall of the installation cavity 210-2, the opening of the positioning cavity 402 faces upward, and the diameter of the positioning cavity 402 gradually increases from bottom to top. The limiting member 403 is arranged above the positioning cavity 402, and the lower end of the limiting member 403 is at least partially inserted in the positioning cavity 402, and the unlocking component is used to drive the limiting member 403 to move upward.

[0152] The insert 401 is inserted from the bottom of the assembly portion 210-1 into the mounting cavity 210-2. The upper end of the insert 401 abuts against the clamping member 4032 in the stopper 403, pushing the stopper 403 upward. Since the diameter of the positioning cavity 402 gradually increases from bottom to top, the insert 401 pushes the stopper 403 upward while also pushing the insert 401 away from the axis of the water-stirring member 200, allowing the insert 401 to smoothly enter the stopper 403. As the insert 401 is inserted, when the clamping member 4032 enters the limiting groove, the limiter 403 moves downward. The end of the clamping member 4032 closer to the axis of the water-stirring member 200 abuts against the bottom of the limiting groove, while the end of the clamping member 4032 farther from the axis of the water-stirring member 200 abuts against the inner wall of the positioning cavity 402, thereby achieving axial positioning of the insert 401.

[0153] In this embodiment, the driven portion 405 of the unlocking assembly is disposed on the stopper 403, specifically, at the end of the stopper 403 away from the positioning cavity 402. A hollow stopper post 4051 of the driven portion 405 extends upward from the top of the stopper 403. An extension plate 4052 of the driven portion 405 extends radially away from the axis of the agitating member 200 from the outer wall of the hollow stopper post 4051. The extension plate 4052 of the driven portion 405 abuts the inner edge of the driving portion 404 via an inclined surface that slopes upward away from the axis of the agitating member 200. When the driving portion 404 moves toward the axis of the agitating member 200, it compresses the end of the extension plate 4052, pushing the stopper 403 upward.

[0154] As shown in Figures 7 and 10, in this embodiment, the driving part 404 is columnar, and the end of the driving part 404 close to the axis of the water-stirring member 200 is provided with an abutting part 4041 that protrudes toward the direction close to the axis of the water-stirring member 200 and abuts against the end of the extension plate 4052 away from the axis of the water-stirring member 200.

The end of the extension plate 4052 is inserted into the first guide groove 4042 and abuts against the bottom of the first guide groove 4042. The end of the extension plate 4052 is configured as an inclined surface that slopes upward from bottom to top away from the axis of the water-stirring member 200. The bottom of the first guide groove 4042 abuts against the end of the driven portion 405. In this embodiment, the provision of the first guide groove 4042 enhances the guiding effect on the movement of the driven portion 405, thereby achieving circumferential positioning of the driven portion 405.

[0157] Preferably, in this embodiment, an avoidance groove 4043 for avoiding the upper end of the extension plate 4052 is provided on the driving part 404 above the abutting part 4041, so that when the driving part 404 moves in the direction close to the axis of the water-stirring member 200, the driven part 405 moves upward under the push of the driving part 404, and the upper end of the extension plate 4052 away from the axis of the water-stirring member 200 is inserted into the avoidance groove 4043 to prevent mutual interference with the driving part 404, thereby ensuring the moving distance of the driving part 404 in the direction close to the axis of the water-stirring member 200 and improving the compactness of the matching structure between the driving part 404 and the driven part 405.

The provision of the guide sleeve 407 can further enhance the guiding effect on the movement of the driven portion 405.

[0159] In this embodiment, a first elastic member is disposed between the driven portion 405 and the top inner wall of the installation cavity 210-2, for driving the driven portion 405 downward. The first elastic member provides a tendency for the positioning cavity 402 and the limiting member 403 to approach each other. Specifically, the first elastic member is a compression spring, which is sleeved around the outer periphery of the guide sleeve 407. One end of the first elastic member abuts the top inner wall of the installation cavity 210-2, and the other end of the first elastic member abuts the extension plate 4052. The first elastic member is compressed to a certain extent, causing the limiting member 403 and the positioning cavity 402 to approach each other, thereby locking the inserted member 401 therein.

The direction of the water stirring rib 220 is at an angle to the rotation direction of the water stirring member 200, and is used to stir the washing water on the side of the water stirring member 200 in the washing tub 100.

[0167] In this embodiment, the assembly portion 210-1 of the water-stirring member 200 is a portion of the support column 210 of the water-stirring member 200. That is, in this embodiment, the support column 210 of the water-stirring member 200 includes two parts. The first part of the support column 210 is the assembly portion 210-1, and the second part of the support column 210 extends upward from the top of the assembly portion 210-1. The second part of the support column 210 corresponds to the water-stirring portion of the water-stirring member, and the outer peripheral wall of the second part of the support column 210 is provided with a water-stirring rib 220.

[0168] In this embodiment, the assembly portion 210-1 of the water-stirring component 200 includes an outer cover and a mounting plate that are interlocked to form an installation cavity 210-2.

[0175] 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.

[0176] 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.

In this embodiment, by providing a rotatable engagement between the support column and the bottom of the tub, the bottom disc-shaped stirring portion is eliminated, which can reduce the coverage area of ​​the gap between the water-stirring member and the bottom of the tub, thereby alleviating the retention of dirt. At the same time, the size of the water seal structure can be reduced, reducing the damping of the rotational action of the water-stirring member.

[0183] Preferably, in this embodiment, the surface of the support column 210 that contacts the water seal structure 500 is a metal surface. A metal insert is provided at the lower end of the support column 210. The support column 210 contacts the water seal structure 500 through the metal insert, which makes the lower end surface of the support column 210 smooth, thereby further improving the sealing effect between the support column 210 and the water seal structure 500 and reducing the damping force between the two.

[0213] Example 4

[0214] As shown in Figures 15 and 16, this embodiment provides a washing tub assembly for a washing machine, and a washing machine having the same. In this embodiment, below the point where the radius of the water-stirring member 200 is the largest, the distance between the sidewall of the support column 210 and the tub wall of the washing tub 100 decreases as the height increases.

[0215] 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.

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.

[0218] 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.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] 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 .

[0225] In a preferred embodiment of this invention, as shown in Figure 16, the upper surface of the water stirring tray 230 is a curved surface with a central region higher than the outer peripheral region. 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.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] 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.

[0230] 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.

[0231] 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.

[0232] 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.

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] 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] Example 5

[0243] An embodiment of the present invention provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly, wherein the washing device may be a washing machine, a washer-dryer, a care machine, or other washing device having a clothes washing function.

[0244] 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 110 connected to the washing tub 100.

[0245] During the washing process, the deceleration clutch device performs a washing operation. Driven by the driving device, the stirring shaft 300 drives the water stirring member 200 to rotate, while the dehydration shaft 110 is fixed, so that the washing tub 100 remains stationary. Alternatively, the dehydration shaft 110 and the stirring shaft 300 rotate in opposite directions, driving the washing tub 100 and the water stirring member 200 to rotate in opposite directions. The relative rotation between the water stirring member 200 and the washing tub 100 agitates the clothes and the wash water in the tub, achieving a cleaning effect on the clothes. During the dehydration process, the deceleration clutch device performs a dehydration operation. Driven by the driving device, the stirring shaft 300 and the dehydration shaft 110 rotate synchronously at high speed, thereby driving the water stirring member 200 and the washing tub 100 to rotate synchronously at high speed, and using centrifugal force to spin the clothes in the tub.

[0246] However, lint and dirt shed during the washing process mix into the wash water. If there is a large, narrow gap between the agitating member 200 and the washing tub 100, these lint and dirt can easily become lodged in the gap, making it difficult for the water to remove them during the wash cycle. This requires the user to manually disassemble the agitating member 200 for cleaning. If the user fails to clean the gap for a long time, a large amount of dirt can accumulate in the gap between the agitating member 200 and the washing tub 100, particularly between the bottom surface of the agitating member 200 and the bottom 100-3 of the washing tub 100. This can easily breed bacteria and cause secondary contamination of the clothes.

[0247] As shown in FIG. 18 to FIG. 20 , in the embodiment of the present invention, the washing tub 100 is a tub without holes.

[0248] 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.

[0249] 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.

[0250] 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.

[0251] In this embodiment, by providing a water-stirring member 200 extending along the axial direction of the washing tub 100 and providing a water seal structure 500 between the bottom of the tub, closest to its center where the clothes can reach, and the lower end circumference of the water-stirring member 200, the bottom of the washing tub 100 outside the water seal structure 500 can be in contact with the clothes, and the friction between the clothes and the inner surface of the tub bottom prevents lint or other dirt from adhering to the inner surface of the tub bottom. At the same time, the water seal structure 500 can prevent the wash water from flushing dirt to a position where the clothes cannot reach it, 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. Moreover, the provision of the water seal structure 500 can prevent wash water from entering the connection between the stirring shaft 300 and the water-stirring member 200, thereby preventing dirt from accumulating at the connection between the two.

[0252] In this embodiment, the water-stirring member 200 extends axially along the washing tub 100. The lower end of the water-stirring member 200 is rotatably engaged with the bottom of the washing tub 100. An injection-molded insert 250 is provided at least on the circumferential surface of the lower end of the water-stirring member 200. A water seal structure 500 is provided between the injection-molded insert 250 on the circumferential surface of the lower end of the water-stirring member 200 and the center of the bottom, where clothes can reach. The abutment between the injection-molded insert 250 and the water seal structure 500 of the water-stirring member 200 smoothes the lower end surface of the water-stirring member 200, thereby further improving the sealing effect between the water-stirring member 200 and the water seal structure 500 and reducing the damping force between the two.

[0253] Preferably, the injection molded insert 250 is made of metal.

[0254] In this embodiment, the agitating member 200 includes a mounting portion 210-1 and a stirring portion 240. The mounting portion 210-1 extends upward from the lower end of the agitating member 200 for a certain length. It is hollowed out to form a spline groove 210-6 with an open bottom. The upper end of the agitating shaft 300 is inserted into the spline groove 210-6 and is keyed to the mounting portion 210-1, thereby driving the agitating member 200 to rotate. The stirring portion 240 is connected to the upper end of the mounting portion 210-1. When the agitating member 200 rotates relative to the washing tub 100, the stirring portion 240 agitates the wash water and clothing within the tub.

[0255] The water seal structure 500 is disposed between the bottom of the washing tub 100 and the circumferential surface of the assembly portion 210-1. Specifically, an extension wall 100-2 is disposed on the bottom of the washing tub 100 surrounding the assembly portion 210-1, and the water seal structure 500 is disposed between the inner circumference of the extension wall 100-2 and the outer circumferential wall of the assembly portion 210-1. Alternatively, a mounting groove is disposed closest to the center of the bottom where clothes can reach, with the lower end of the assembly portion 210-1 inserted into the mounting groove, and the water seal structure 500 is disposed between the groove wall of the mounting groove and the circumferential surface of the assembly portion 210-1. Alternatively, a mounting groove is disposed closest to the center of the bottom where clothes can reach, and an extension wall 100-2 is disposed on the inner surface of the bottom surrounding the mounting groove. The inner circumference of the extension wall 100-2 is coplanar with the groove wall of the mounting groove, and the water seal structure 500 is disposed between the groove wall of the mounting groove, the inner circumference of the extension wall 100-2, and the circumferential wall of the assembly portion 210-1.

[0256] Alternatively, a mounting groove is provided on the bottom of the tub, the upper end of the dehydration shaft 110 is connected to the bottom of the tub 100, corresponding to the mounting groove. The tub 100 and the dehydration shaft 110 are connected via a connector that passes through the inside of the tub bottom and connects to the dehydration shaft 110. The connector is disposed within the mounting groove. The lower end of the water-stirring member 200 corresponds to the mounting groove and is spaced apart from the bottom of the mounting groove. The extension wall 100-2 is disposed around the mounting groove, the inner diameter of the extension wall 100-2 being larger than the diameter of the mounting groove. The water seal structure 500 is disposed between the inner periphery of the extension wall 100-2 and the lower end circumferential surface of the water-stirring member 200.

[0257] Preferably, in this embodiment, the water seal structure 500 is annular and is disposed between the inner periphery of the extension wall 100 - 2 and the peripheral surface of the assembly portion 210 - 1 .

[0258] In this embodiment, the mounting portion 210-1 is cylindrical and coaxially disposed with the washing tub 100. The extension wall 100-2 is coaxially disposed with the washing tub 100. The water seal structure 500 comprises a soft body and a skeleton disposed within the soft body. Specifically, the soft body comprises a first extension portion 500-1 that seals with the inner periphery of the extension wall 100-2, a second extension portion 500-2 that seals with the outer periphery of the mounting portion 210-1, and a third extension portion 500-11 connected between the upper ends of the first extension portion 500-1 and the second extension portion 500-2.

[0259] The first extension portion 500-1 and the second extension portion 500-2 are both configured to be cylindrical, and the first extension portion 500-1 and the second extension portion 500-2 extend axially along the extension wall 100-2 and the assembly portion 210-1, respectively. The outer peripheral wall of the first extension portion 500-1 is fitted and sealed with the inner periphery of the extension wall 100-2, and the inner periphery of the second extension portion 500-2 is fitted and sealed with the outer periphery of the assembly portion 210-1. The third extension portion 500-11 extends from the upper end of the first extension portion 500-1 in a direction close to the axis of the washing barrel 100, and is connected as a whole with the upper end of the second extension portion 500-2.

[0260] The skeleton is arranged inside the soft body, and its extending direction is the same as that of the soft body.

[0261] In some possible embodiments, the skeleton is provided as a whole, is disposed in the middle of the soft body, and is adapted to the shape of the soft body.

[0262] Preferably, as shown in Figures 18 and 20, in some other possible embodiments, the skeleton includes at least two parts. Specifically, the skeleton includes a first skeleton 500-31 and a second skeleton 500-32, wherein the first skeleton 500-31 is disposed in the first extension portion 500-1 and extends along the extension direction of the first extension portion 500-1, and the upper end of the first skeleton 500-31 at least partially extends into the third extension portion 500-11, and the second skeleton 500-32 is disposed in the second extension portion 500-2 and extends along the extension direction of the second extension portion 500-2, and the upper end of the second skeleton 500-32 at least partially extends into the third extension portion 500-11.

[0263] Preferably, the ends of the first skeleton 500-31 and the second skeleton 500-32 extending into the third extension portion 500-11 are spaced apart from each other.

[0264] In this embodiment, the skeleton and the soft body are arranged in a coordinated manner, and the skeleton is embedded within the soft body to provide support for the shape and position of the first extension portion 500-1 and the second extension portion 500-2 of the soft body, thereby enhancing the strength of the water seal structure 500. By spacing the ends of the first skeleton 500-31 and the second skeleton 500-32 extending into the third extension portion 500-11, the water seal structure 500 can produce corresponding elastic deformation in response to eccentric displacement caused by the rotation of the water stirring member 200, thereby improving the buffering effect of the eccentric displacement caused by the rotation of the water stirring member 200.

[0265] Preferably, in this embodiment, a third skeleton can also be provided in the third extension portion 500-11, and the third skeleton is provided at the interval between the first skeleton 500-31 and the second skeleton 500-32, and the third skeleton extends along the extension direction of the third extension portion 500-11, and the third skeleton and one end of the first skeleton 500-31 and the second skeleton 500-32 extending into the third extension portion 500-11 are staggered in the thickness direction of the third extension portion 500-11, thereby ensuring that the water seal structure 500 has a higher buffering effect on the radial swing of the water stirring member 200 and the service life of the water seal structure 500, and also enabling the water seal structure 500 to have greater supporting strength.

[0266] In this embodiment, the soft body is provided with a sealing lip 500-4, and the water seal structure 500 is sealed with the extension wall 100-2 and the water stirring member 200 via the sealing lip 500-4 on the soft body. Specifically, the soft body is sealed with the inner periphery of the extension wall 100-2 and the outer peripheral wall of the assembly portion 210-1 via the sealing lip 500-4. The sealing lip 500-4 includes a first sealing lip 500-6 provided on the outer periphery of the first extension portion 500-1 and a second sealing lip 500-7 provided on the inner periphery of the second extension portion 500-2. The first sealing lip 500-6 and the second sealing lip 500-7 extend circumferentially along the first extension portion 500-1 and the second extension portion 500-2, respectively, and include multiple turns arranged axially along the first extension portion 500-1 and the second extension portion 500-2. The first extension portion 500-1 is elastically abutted against the inner periphery of the extension portion by the first sealing lip 500-6, and the second extension portion 500-2 is elastically abutted against the outer peripheral wall of the assembly portion 210-1 by the second sealing lip 500-7, thereby achieving sealing.

[0267] Preferably, the first sealing lip 500-6 is configured to be serrated or wavy in a direction protruding away from the axis of the washing tub 100, and its axial cross-section is a plurality of triangles arranged continuously along the axial direction of the first extension portion 500-1, or, the side of its axial cross-section away from the axis of the washing tub 100 is a wavy line.

[0268] The second sealing lip 500 - 7 extends upwardly and tilted in a direction close to the axis of the washing tub 100 .

[0269] The first sealing lip 500 - 6 and the second sealing lip 500 - 7 are both configured to have at least three circles.

[0270] Preferably, the second sealing lip 500-7 is provided with at least three layers arranged from top to bottom, and the axial cross-section of the second sealing lip 500-7 is a triangle, and the length of the side located at the bottom of the triangle is greater than the length of the side located at the top, or, the axial cross-section of the second sealing lip 500-7 is a rectangle inclined upward in the direction close to the axis of the washing tub 100, or, the axial cross-section of the second sealing lip 500-7 is a parallelogram inclined upward in the direction close to the axis of the washing tub 100.

[0271] Preferably, in this embodiment, the second sealing lips 500-7 are of two types, with axial cross-sections of the two types being triangular and rectangular, respectively. The two types of second sealing lips 500-7 are staggered axially along the second extension portion 500-2. The upper edges of the second sealing lips 500-7 with triangular axial cross-sections extend downwardly and tilted toward the axis of the washing tub 100, while the lower edges extend upwardly and tilted toward the axis of the washing tub 100.

[0272] The uppermost end of the first layer of second sealing lip 500-7, located at the uppermost end of the inner periphery of the second extension portion 500-2, is lower than the upper end surface of the second extension portion 500-2. Preferably, the axial cross-section of the second sealing lip 500-7, located at the uppermost end of the inner periphery of the second extension portion 500-2, is triangular, and the upper end of the base of the second sealing lip 500-7 is lower than the upper end surface of the second extension portion 500-2.

[0273] Preferably, the second sealing lip 500-7 is disposed at least on the inner periphery of the second extension portion 500-2, near its upper end. The water seal structure 500 also includes a sleeve 500-12 disposed between the inner periphery of the second extension portion 500-2 below the sealing lip 500-4 and the outer peripheral wall of the assembly portion 210-1. The provision of sleeve 500-12 reduces the relative displacement between the lower end of the second extension portion 500-2 and the lower peripheral surface of the water agitation member 200 when the water seal structure 500 is elastically deformed by the eccentric displacement of the water agitation member 200, thereby ensuring a sealing effect between the upper end of the second extension portion 500-2 and the lower peripheral surface of the water agitation member 200.

[0274] In this embodiment, by arranging a shaft sleeve 500-12 between the second extension portion 500-2 and the lower end circumference of the assembly portion 210-1, and at the same time arranging the first skeleton 500-31 and the second skeleton 500-32 extending to one end of the third extension portion 500-11 to be spaced apart from each other, when the water-stirring member 200 produces radial displacement, the shaft sleeve 500-12 can drive the entire second extension portion 500-2 to produce synchronous displacement, that is, drive the second extension portion 500-2 to follow the deflection of the assembly portion 210-1, so that the deformation of the water seal structure 500 mainly occurs at the third extension portion 500-11, reducing the relative displacement in the radial direction between the assembly portion 210-1 and the second extension portion 500-2, thereby avoiding the situation where the second sealing lip 500-7 on the other side is excessively squeezed by the assembly portion 210-1 and causes water leakage.

[0275] The outer circumferential wall of the first extension portion 500-1 is aligned with the inner circumference of the extension wall 100-2. The lower end of the first extension portion 500-1 abuts the inner surface of the tub bottom, while the upper end is substantially flush with the upper end of the extension wall 100-2.

The water-stirring component 200 is connected to the stirring shaft 300 through the internal spline of the first insert 250-1. By providing the external spline, it can be more tightly connected to the injection molded body of the water-stirring component 200, and at the same time, it can better transmit torque. The axial cross section of the second insert 250 - 2 is U-shaped. The second insert 250 - 2 covers the lower end circumference of the water-stirring member 200 and the lower end surface of the water-stirring member 200 on the outer periphery of the first insert 250 - 1 .

[0293] Example 6

[0294] As shown in FIG. 22 to FIG. 24 , in an embodiment of the present invention, a washing tub assembly is introduced.

[0295] 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.

[0296] In this embodiment, a drain port 100 - 32 and a drain valve 600 for keeping the drain port 100 - 32 normally closed are provided on the bottom of the barrel on the outer periphery of the water stirring member 200 .

[0297] Specifically, in this embodiment, a drain outlet 100-32 is provided on the area of ​​the barrel bottom extending outward from the lower end of the water stirring member 200 to the barrel wall, that is, the drain outlet 100-32 of the washing barrel 100 is provided on the washing surface 100-31 of the barrel bottom, and the bottom disc-shaped stirring portion is eliminated, which can avoid the water stirring member 200 hindering the washing water from flowing to the drain outlet 100-32 on the washing surface 100-31, thereby improving the drainage speed.

[0298] A drain valve is provided at the drain outlet, and 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. At the same time, 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.

[0299] In this embodiment, a driving component is provided at the bottom of the water collection device, corresponding to the drain valve 600. The driving component is used to drive the drain valve 600 to open. When the washing machine is washing, the working end of the driving component 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 the point where the drain valve 600 corresponds to the working end of the driving component. The working end of the driving component then extends upward, pushing the valve plug 600-1 of the drain valve 600 upward, thereby opening the drain port 100-32.

[0300] Preferably, in this embodiment, 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 to drive the drain valve 600 to open, ensuring normal drainage.

[0301] 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.

[0302] Preferably, as shown in FIG. 22 and FIG. 23 , in this embodiment, a valve cover 800 covering the drain outlet 100 - 32 is provided on the inner surface of the barrel bottom, and a hollow hole 803 for washing water to pass through is provided on the wall of the valve cover 800 .

[0303] In this embodiment, by providing a valve cover 800 on the inner surface of the tub bottom, wash water is discharged through the hollow holes 803 in the valve cover 800. This prevents debris such as clothing and lint from entering the tub 100, thereby preventing the clothing from obstructing the drain valve 600 from closing the drain outlet 100-32. This improves the operational stability of the drain valve 600 and filters out debris such as lint in the wash water, preventing it from entering the drain outlet 100-32 and potentially clogging the drain outlet 100-32, the drainage pipeline, and the user's home floor drain. Furthermore, by locating the drain outlet 100-32 in the area where the lower end of the water-stirring member 200 extends outwardly from the tub wall, the valve cover 800 can contact the clothing in the tub. The friction of the clothing prevents debris such as lint from clogging the hollow holes 803 in the valve cover 800, thereby ensuring efficient drainage.

[0304] At the same time, it can also enrich the structure of the washing surface 100-31 at the bottom of the barrel and improve the washing effect on clothes.

[0305] As shown in Figure 24, in this embodiment, the valve cover 800 includes a top wall 801 and a surrounding wall 802. The top wall 801 and the surrounding wall 802 are integrally formed to form the valve cover 800. The projection of the valve cover 800 on the bottom of the tub covers the drain opening 100-32. The lower end of the surrounding wall 802 is arranged around the drain opening 100-32 and abuts against the inner surface of the tub bottom around the drain opening 100-32, thereby covering the drain opening 100-32 within the valve cover 800. The top wall 801 and / or the surrounding wall 802 of the valve cover 800 are provided with a hollow hole 803 for draining wash water.

[0306] In this embodiment, the top wall 801 of the valve cover 800 is arranged above the drain outlet 100-32, and the surrounding wall 802 of the valve cover 800 extends downward from the edge of the top wall 801, and the lower end of the surrounding wall 802 abuts against the inner surface of the barrel bottom outside the drain outlet 100-32; the hollow hole 803 is arranged on the top wall 801 and / or the surrounding wall 802.

[0307] In this embodiment, the valve cover 800 can be of any shape as long as the drain outlet 100 - 32 can be covered within the valve cover 800 .

[0308] In some possible embodiments, the projection coverage of the top wall 801 of the valve cover 800 on the bottom of the barrel is smaller than the range of the drain outlet 100-32, and the surrounding wall 802 extends obliquely from top to bottom toward the periphery of the drain outlet 100-32, and the lower end of the surrounding wall 802 is arranged around the drain outlet 100-32.

[0309] In other possible embodiments, the coverage of the projection of the top wall 801 of the valve cover 800 on the bottom of the barrel is greater than or equal to the range of the drain outlet 100-32, and the surrounding wall 802 extends vertically from top to bottom, or the surrounding wall 802 extends obliquely from top to bottom toward the periphery of the projection of the top wall 801 on the bottom of the barrel.

[0310] In this embodiment, the top wall 801 is arranged opposite to the drain outlet 100 - 32 , and the top wall 801 can be arranged in a horizontal form, an inclined form, or a curved form.

[0311] Preferably, in this embodiment, the top wall 801 of the valve cover 800 is set to a regular plane, an arc-shaped curved surface, or a wavy curved surface to avoid the presence of four corners that are easy to harbor dirt and grime.

[0312] Preferably, in this embodiment, the top wall 801 is arranged above the drain outlet 100-32, facing the drain outlet 100-32, the projection of the top wall 801 of the valve cover 800 on the bottom of the barrel covers the drain outlet 100-32, and the surrounding wall 802 extends vertically downward from the edge of the top wall 801.

[0313] Preferably, in this embodiment, the connection between the top wall 801 and the side wall of the valve cover 800 is provided with an arc-shaped chamfer. This facilitates the passage of clothing through the valve cover 800 during the washing process, preventing the valve cover 800 from damaging the clothing. Furthermore, this further reduces the number of hard-to-clean corners on the valve cover 800.

[0314] Preferably, in this embodiment, the valve cover 800 is configured in an elongated strip shape, with the length of the valve cover 800 being perpendicular to a line connecting the rotation center of the water agitation member 200 and the center of the drain outlet 100-32. This reduces the resistance of the valve cover 800 to the laundry, improving the smoothness of laundry movement within the washing tub 100.

[0315] The top wall 801 of the valve cover 800 is configured to be curved downward. Specifically, the top wall 801 of the valve cover 800 is curved downward in a direction away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32. Preferably, the end of the top wall 801 of the valve cover 800 away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32 is substantially in contact with the inner surface of the bottom of the barrel. In this embodiment, the clothes in the barrel mainly move along the circumferential direction of the washing barrel 100 under the stirring of the water stirring member 200. Through the above-mentioned configuration, the resistance of the valve cover 800 to the rotation of the clothes can be further reduced, so that the clothes can pass smoothly through the area where the valve cover 800 is located.

[0316] In this embodiment, the top wall 801 of the valve cover 800 is basically in contact with the inner surface of the barrel bottom, away from the end of the vertical line between the rotation center of the water-stirring member 200 and the center of the drain outlet 100-32. Specifically, the end of the upper end surface of the valve cover 800 and the inner surface of the barrel bottom can be smoothly transitioned, or the end of the upper end surface of the valve cover 800 is slightly higher than the inner surface of the barrel bottom, thereby further reducing the resistance of the valve cover 800 to the circumferential movement of the clothes in the washing barrel 100.

[0317] Preferably, in this embodiment, the upper end surfaces of the valve cover 800 at both ends are smoothly transitioned to the inner surface of the barrel bottom through a rounded corner or a downwardly inclined slope that bends downward in the direction away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32.

[0318] Further preferably, the width of the valve cover 800 gradually decreases in a direction away from a vertical line between the rotation center of the water-stirring member 200 and the center of the drain outlet 100 - 32 .

[0319] In this embodiment, through the above-mentioned arrangement, when the clothes pass through the area on the inner surface of the barrel bottom where the valve cover 800 is located, they can move smoothly along the upper end surface of the valve cover 800, the side close to the water-stirring component 200, and the side away from the water-stirring component 200. On the one hand, it can facilitate the passage of clothes through this area. On the other hand, it can utilize the contact and friction between the clothes and the valve cover 800 to avoid dirt from adhering to the valve cover 800, and avoid the formation of dead corners that are difficult to clean on the washing surface 100-31 of the barrel bottom due to the arrangement of the valve cover 800.

[0320] Still more preferably, in this embodiment, the valve cover 800 is bilaterally symmetrical with respect to a vertical line between the rotation center of the water-stirring member 200 and the center of the drain outlet 100 - 32 .

[0321] In this embodiment, the valve cover 800 is spaced apart from the water stirring member 200 at one end and the barrel wall at the other end, and the valve cover 800 is spaced apart from the barrel wall at both ends of the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32 at the other end, so that clothes can pass smoothly between the water stirring member 200 and the valve cover 800 and between the valve cover 800 and the barrel wall, avoiding the situation where clothes are stuck.

[0322] In this embodiment, the drain outlet 100-32 can be of any shape. Preferably, the drain outlet 100-32 is circular or elliptical. The center of the drain outlet 100-32 is the center of the circular drain outlet 100-32, or the midpoint of the line connecting the two foci of the elliptical drain outlet 100-32. The vertical line between the rotation center of the water-stirring member 200 and the center of the drain outlet 100-32 is perpendicular to the rotation center of the water-stirring member 200.

[0323] Preferably, in this embodiment, the water stirring member 200 is coaxially arranged with the washing tub 100 , and a vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100 - 32 extends along the radial direction of the washing tub 100 .

[0324] In this embodiment, the hollow holes 803 on the wall of the valve cover 800 include a first hollow hole 8031 ​​arranged on the top wall 801 of the valve cover 800, and a second hollow hole 8032 arranged on the surrounding wall 802 of the valve cover 800. There are multiple first hollow holes 8031 ​​and second hollow holes 8032 respectively.

[0325] In this embodiment, the first hollow hole 8031 ​​and the second hollow hole 8032 are both small holes, which can prevent debris such as lint in the washing water from passing through to a certain extent. The first hollow hole 8031 ​​and the second hollow hole 8032 can be of any shape.

[0326] Preferably, in some specific embodiments of the present invention, the first hollow hole 8031 ​​and the second hollow hole 8032 can be small circular holes, can be strip-shaped holes, or can be a plurality of coaxially arranged annular holes.

[0327] In this embodiment, the first hollow hole 8031 ​​is a small round hole, and the second hollow hole 8032 is configured as a grille hole.

[0328] Specifically, in this embodiment, the second hollow hole 8032 is set at the lower end of the surrounding wall 802, and is U-shaped with the opening facing downward, and is formed by being recessed upward from the lower end surface of the surrounding wall 802. There are multiple second hollow holes 8032 arranged along the length direction of the surrounding wall 802.

[0329] When the valve cover 800 is mounted on the tub bottom, the lower end of the surrounding wall 802 of the valve cover 800 abuts against the inner surface of the tub bottom, which seals the opening of the U-shaped second hollow hole 8032 to form a grille. This allows wash water to flow between the cavity of the valve cover 800 and the washing tub 100 during the washing process, improving the flushing effect within the valve cover 800 and ensuring drainage, allowing all wash water in the washing tub 100 to be discharged through the second hollow hole 8032.

[0330] In some possible embodiments, the hollow holes may be distributed throughout the entire valve cover. Specifically, the first hollow holes may cover the entire top wall of the valve cover, and the second hollow holes may cover the entire surrounding wall of the valve cover. The hollow holes may also be concentrated in a certain area of ​​the top wall and / or surrounding wall.

[0331] Preferably, in this embodiment, the second hollow holes 8032 are concentratedly arranged on a side of the surrounding wall 802 of the valve cover 800 close to the water stirring member 200 and a side away from the water stirring member 200, which can improve drainage efficiency.

[0332] Further preferably, in this embodiment, the first hollow holes 8031 ​​are concentratedly arranged in the middle of the top wall 801 of the valve cover 800.

[0333] Still more preferably, the first hollow holes 8031 ​​are concentratedly arranged within a range covered by a vertical projection of the drain outlet 100 - 32 on the top wall 801 of the valve cover 800 .

[0334] In this embodiment, the top wall 801 of the valve cover 800 is configured to be bent downward, which can further increase the layout area for setting the first hollow holes 8031, which is conducive to increasing the number of the first hollow holes 8031.

[0335] In this embodiment, the valve cover 800 is detachably mounted on the bottom of the barrel.

[0336] In a specific embodiment of the present invention, the valve cover 800 is mounted on the bottom of the barrel by screws. Specifically, the valve cover 800 is fixed by at least two screws. A vertically downwardly extending connection groove 804 is provided on the top wall 801 of the valve cover 800, near both ends of the valve cover 800. The bottom of the connection groove 804 is provided with a through hole for the screw shaft to pass through. Preferably, the inner wall of the through hole is provided with an internal thread that matches the external thread on the screw shaft. The barrel bottom is provided with a threaded hole that matches the screw. The screw shaft passes through the through hole on the bottom of the connection groove 804 and is tightened into the threaded hole on the barrel bottom. The head of the screw is embedded in the connection groove 804 and abuts against the bottom of the connection groove 804, thereby achieving the installation of the valve cover 800. At the same time, the connection groove 804 can hide the head of the screw, preventing the screw head from damaging clothing.

[0337] In this embodiment, the drain valve 600 includes a valve plug 600 - 1 and an elastic component for driving the drain valve 600 to close.

[0338] In this embodiment, the valve plug 600-1 is arranged at the drain outlet 100-32, and the sealing part of the valve plug 600-1 is arranged in the cavity of the valve cover 800, moving from top to bottom to block the drain outlet 100-32; the elastic component is arranged between the valve plug 600-1 and the bottom of the barrel to drive the valve plug 600-1 to move downward.

[0339] Specifically, the shape of the sealing part of the valve plug 600-1 is adapted to the shape of the drain outlet 100-32, and the outer peripheral wall of the sealing part is inclined from top to bottom toward the center of the sealing part. The valve plug 600-1 is inserted into the drain outlet 100-32 from top to bottom, and the sealing part is at least partially inserted into the drain outlet 100-32. The outer peripheral wall of the sealing part elastically abuts against the drain outlet 100-32 to close the drain outlet 100-32.

[0340] Preferably, in this embodiment, the inner diameter of the upper end of the drain port 100-32 gradually decreases from top to bottom, and the sealing portion of the valve plug 600-1 is embedded in the upper end of the drain port 100-32 from top to bottom to seal the drain port 100-32. Preferably, the upper end surface of the valve plug 600-1 is substantially flush with the inner surface of the barrel bottom surrounding the drain port 100-32.

[0341] In this embodiment, the upper end surface of the valve plug 600-1 is basically flush with the inner surface of the barrel bottom around the drain outlet 100-32. The upper end surface of the valve plug 600-1 can be flush with the inner surface of the barrel bottom around the drain outlet 100-32, or the upper end surface of the valve plug 600-1 can be slightly higher than the inner surface of the barrel bottom around the drain outlet 100-32, or the upper end surface of the valve plug 600-1 can be slightly lower than the inner surface of the barrel bottom around the drain outlet 100-32.

[0342] In this embodiment, when the drain valve 600 is opened, the sealing portion of the valve plug 600-1 moves into the cavity of the valve cover 800, and the washing water enters the cavity of the valve cover 800 from the hollow hole 803 on the valve cover 800, and then flows out from the drain port 100-32.

[0343] In a specific embodiment of the present invention, the drain valve 600 also includes a supporting component, which is fixedly installed at the bottom of the washing tub 100 and extends to the bottom of the drain outlet. The valve plug 600-1 of the drain valve 600 can be relatively slidably installed on the supporting component.

[0344] The supporting component includes a fixing part and a sleeve part. The fixing part is fixedly installed at the bottom of the washing bucket 100 and extends to the bottom of the drain outlet. It is fixedly connected to the sleeve part, and the sleeve part has a hollow slide. The valve plug 600-1 of the drain valve 600 includes a sealing part and a sliding rod. The sliding rod is slidably arranged in the hollow slide of the sleeve part to realize the sealing part to block / conduct the drain outlet.

[0345] The sealing portion further comprises a sealing gasket which is an annular structure and is arranged on the outer peripheral wall of the sealing portion. The sealing portion abuts against the inner wall of the drain outlet through the sealing gasket.

[0346] To maintain the sealing portion's self-sealing function and restore its seal after drainage, drain valve 600 includes an elastic component. One end of the elastic component abuts against the support component, and the other end abuts against valve plug 600-1. This elastic component deforms when the sealing portion slides away from the drain outlet, achieving elastic restoration of the sealing portion. Initially, the elastic component is compressed, maintaining the sealing portion's seal against the upper end of the drain outlet.

[0347] As an implementation of this embodiment, the elastic component is a compression spring, which is sleeved in the hollow slide of the sleeve portion. One end of the compression spring stops at the sleeve portion, and the other end stops at the bottom of the valve plug 600-1.

[0348] Furthermore, a screw is installed at the end of the sliding rod, and the upper end of the sleeve portion has a limit step extending a certain distance toward the inside of the hollow slideway. The compression spring is sleeved on the center rod, with one end resting on the screw and the other end resting on the limit step.

[0349] 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.

[0350] 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.

[0351] 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.

[0352] 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.

[0353] 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.

[0354] 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.

[0355] 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.

[0356] 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.

[0357] 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.

[0358] 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.

[0359] 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.

[0360] 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.

[0361] 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 .

[0362] 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.

[0363] 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.

[0364] 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.

[0365] 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.

[0366] 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.

[0367] 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 .

[0368] 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.

[0369] 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.

[0370] 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 , and preferably 95% or more of the total area of ​​the bottom of the washing tub 100 .

[0371] 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.

[0372] 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.

[0373] 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.

[0374] 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 .

[0375] 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.

[0376] 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 .

[0377] 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.

[0378] 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.

[0379] 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.

[0380] 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.

[0381] 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.

[0382] 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.

[0383] 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.

[0384] 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.

[0385] 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:

[0386] During the drainage process of the washing tub 100, the water stirring member 200 rotates to speed up the drainage.

[0387] 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.

[0388] 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.

[0389] 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.

[0390] 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.

[0391] 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.

[0392] 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.

[0393] 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.

[0394] 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.

[0395] 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.

[0396] 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.

[0397] 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.

[0398] 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.

[0399] 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.

[0400] 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.

[0401] 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.

[0402] 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.

[0403] 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.

[0404] 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.

[0405] 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.

[0406] 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.

[0407] 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 .

[0408] Example 7

[0409] An embodiment of the present invention provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly, wherein the washing device may be a washing machine, a washer-dryer, a care machine, or other washing device having a clothes washing function.

[0410] Specifically, the washing tub assembly includes a washing tub 100 and a water-stirring member 200 rotatably disposed within the washing tub 100. The washing apparatus includes at least the above-mentioned washing tub assembly and a driving device, which 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.

[0411] More specifically, 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 110 connected to the washing tub 100.

[0412] During the washing process, the deceleration clutch device performs a washing operation. Driven by the driving device, the stirring shaft 300 drives the water stirring member 200 to rotate, while the dehydration shaft 110 is fixed, so that the washing tub 100 remains stationary. Alternatively, the dehydration shaft 110 and the stirring shaft 300 rotate in opposite directions, driving the washing tub 100 and the water stirring member 200 to rotate in opposite directions. The relative rotation between the water stirring member 200 and the washing tub 100 agitates the clothes and the wash water in the tub, achieving a cleaning effect on the clothes. During the dehydration process, the deceleration clutch device performs a dehydration operation. Driven by the driving device, the stirring shaft 300 and the dehydration shaft 110 rotate synchronously at high speed, thereby driving the water stirring member 200 and the washing tub 100 to rotate synchronously at high speed, and using centrifugal force to spin the clothes in the tub.

[0413] However, lint and dirt shed during the washing process mix into the wash water. If there is a large, narrow gap between the agitating member 200 and the washing tub 100, these lint and dirt can easily become lodged in the gap, making it difficult for the water to remove them during the wash cycle. This requires the user to manually disassemble the agitating member 200 for cleaning. If the user fails to clean the gap for a long time, a large amount of dirt can accumulate in the gap between the agitating member 200 and the washing tub 100, particularly between the bottom surface of the agitating member 200 and the bottom 100-3 of the washing tub 100. This can easily breed bacteria and cause secondary contamination of the clothes.

[0414] As shown in Figures 25 to 27, in an embodiment of the present invention, an upwardly protruding assembly platform is provided on the inner surface of the bottom of the washing tub 100; the bottom of the water stirring member 200 is provided with an assembly groove 210-10 whose inner diameter is adapted to the outer diameter of the assembly platform, and the water stirring member 200 is mounted on the assembly platform through the assembly groove 210-10, forming a gap between the assembly platform and the assembly platform, which first extends upward and then extends toward the direction close to the axis of the washing tub 100, and the gap is closed at one end close to the axis of the washing tub 100. In this embodiment, a gap is formed between the water-stirring member 200 and the bottom of the washing tub 100, which first extends upward and then extends toward the axis of the washing tub 100. By closing one end of the gap close to the axis of the washing tub 100, the air pressure in the gap between the water-stirring member 200 and the bottom of the washing tub 100 can be utilized to form an air seal, thereby preventing the washing water from flowing toward the inner periphery of the gap. This prevents impurities such as dirt and lint that fall from clothes from entering and accumulating in the gap between the water-stirring member 200 and the bottom of the tub, effectively avoiding the problem of dirt and grime easily accumulating between the water-stirring member 200 and the bottom of the tub and being difficult to clean, thereby improving the user experience.

[0415] The washing machine also includes a drive device, which is transmission-connected to the water-stirring member 200 via a stirring shaft 300 and to the washing tub 100 via a dehydration shaft 110. The stirring shaft 300 and the dehydration shaft 110 are coaxially arranged, and a water seal is provided between the stirring shaft 300 and the dehydration shaft 110 to ensure sealing between them. Water seal structures 500 are respectively provided between the stirring shaft 300 and the water-stirring member 200 and between the dehydration shaft 110 and the washing tub 100. A second water seal structure 502 between the stirring shaft 300 and the water-stirring member 200 and a first water seal structure 501 between the dehydration shaft 110 and the washing tub 100 seal the gap between the water-stirring member 200 and the bottom of the washing tub 100 at the end near the axis of the washing tub 100.

[0416] Specifically, the upper end of the dehydration shaft 110 is plugged into the bottom of the washing barrel 100 and extends above the inner surface of the bottom of the washing barrel 100. An upwardly extending extension wall 100-2 is provided around the dehydration shaft 110 on the inner surface of the bottom, and a first water seal structure 501 is provided between the inner periphery of the extension wall 100-2 and the outer peripheral wall of the dehydration shaft 110; the extension wall 100-2, the first water seal structure 501 and the upper end of the dehydration shaft 110 constitute an assembly table; preferably, the upper end surface of the extension wall 100-2, the upper end surface of the first water seal structure 501, and the upper end surface of the dehydration shaft 110 are basically flush.

By providing the external spline, the water-stirring member 200 can be more tightly connected to the injection-molded body of the water-stirring member 200, and at the same time, the torque can be better transmitted.
