[0065] Embodiment 1

[0066] As Figures 1 to 4 shown, in the embodiment of the present invention, a washing tub assembly of a washing device is introduced. The washing tub assembly includes a washing tub 100 and a water stirring member 200 installed on the washing tub 100. When the washing device operates, the rotation of the water stirring member 200 drives the rotation of the washing water in the washing tub 100, so as to realize the washing of the clothes in the washing tub 100.

[0067] In this embodiment, the washing tub 100 is a tub without holes.

[0068] 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 likely to accumulate in the gap between the bottom of the water stirring member 200 and the bottom of the tub. The area in this gap does not contact the clothes. Therefore, the impurities in the gap are in a state of long-term accumulation, and they cannot be effectively cleaned simply by flushing, which is likely to breed bacteria and contaminate the clothes with the washing water.

[0069] 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 the washing water from entering the gap between the water stirring member 200 and the bottom of the washing tub 100. Thus, it is possible to prevent dirt, lint and other impurities dropped from the clothes from entering and accumulating in the gap between the water stirring member 200 and the bottom of the tub, improve the cleanliness of the space in the washing tub 100 that contacts the washing water, and thus improve the washing effect on the clothes.

[0070] In this embodiment, the water stirring member 200 extends along the axial direction of the washing tub 100. The lower end of the water stirring member 200 is inserted and rotatably engaged with the inner surface of the bottom of the washing tub 100. A water seal structure 500 is provided between the circumferential surface of the lower end of the water stirring member 200 and the center of the bottom of the tub closest to the center where the clothes can reach.

[0071] In this embodiment, by arranging the water stirring member 200 to extend 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 laundry can reach and the circumferential surface of the lower end of the water stirring member 200, the bottom of the washing tub 100 outside the water seal structure 500 can contact the laundry. The friction between the laundry and the inner surface of the tub bottom is utilized to prevent 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 washing water from flushing the dirt to positions inaccessible to the laundry, effectively avoiding the problem that it is easy for dirt to accumulate between the water stirring member 200 and the tub bottom and is difficult to clean, thus improving the user experience.

[0072] 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 water stirring ribs 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 ribs 220 are arranged on the circumferential side of the support column 210 and extend along the length direction of the support column 210. The lower end of the support column 210 is in rotational cooperation with the bottom of the washing tub 100.

[0073] An installation groove 100-1 is provided at the bottom of the tub closest to its center where the laundry 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 arranged between the groove wall of the installation groove 100-1 and the circumferential surface of the lower end of the support column 210.

[0074] Specifically, in this embodiment, the stirring shaft 300 of the washing device extends coaxially 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 installation groove 100-1 is arranged on the inner surface of the bottom of the washing tub 100 and is coaxially arranged with the washing tub 100. The installation groove 100-1 corresponds to the lower end of the support column 210. At least part of the lower end of the support column 210 is inserted into the installation groove 100-1 and forms a rotational pair with the groove wall of the installation groove 100-1. The water seal structure 500 is arranged between the groove wall of the installation 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. The circumferential side of the support column 210 is disposed 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 bottom of the washing tub 100 outside the support column 210. By using the friction between the clothes and the support column 210 and between the clothes and the part of the bottom of the tub outside the support column 210, it is possible to prevent lint or other dirt from adhering to the circumferential side of the support column 210 and the bottom of the tub outside the support column 210, effectively avoiding the problem that it is easy to hide dirt between the water stirring member 200 and the bottom of the tub and difficult to clean, and improving the user experience.

[0077] The water seal structure 500 is annular and is disposed between the wall of the installation groove 100-1 and the lower end circumferential surface of the support column 210; the outer circumference of the water seal structure 500 is connected to the wall of the installation groove 100-1, and the inner circumference of the water seal structure 500 is elastically abutted against the lower end circumferential surface of the support column 210.

The support column 210 is rotationally engaged with the wall of the installation groove 100-1 through the connecting portion 215, and the water seal structure 500 is disposed between the connecting portion 215 of the support column 210 and the inner wall of the installation groove 100-1.

[0079] An embedding groove is coaxially provided at the notch of the installation groove 100-1. The diameter of the embedding groove is larger than the diameter of the installation groove 100-1. The water seal structure 500 is disposed in the embedding groove, its lower end surface is attached to the bottom of the embedding groove, and its upper end surface is substantially flush with the inner surface of the bottom of the tub. Preferably, the outer diameter of the water seal structure 500 is greater than or equal to the inner diameter of the embedding groove, and the elastic abutment between the inner edge of the water seal structure 500 and the lower end circumferential surface of the support column 210.

[0080] In this embodiment, the statement that "the upper end surface of the water seal structure 500 is substantially flush with the inner surface of the bottom of the tub" may specifically be that the upper end surface of the water seal structure 500 is flush with the inner surface of the bottom of the tub, or that the upper end surface of the water seal structure 500 protrudes from the inner surface of the bottom of the tub, or that the upper end surface of the water seal structure 500 is slightly lower than the inner surface of the bottom of the tub.

[0081] As Figures 2 to 4 shown, in this embodiment, the water seal structure 500 includes a rubber body and a spring ring 500-5. The rubber body is disposed in the embedding groove and includes a rubber body main body adapted to the embedding groove and a sealing lip 500-4 disposed between the inner circumference of the rubber body main body and the lower end circumferential surface of the support column 210 for elastic abutment. The spring ring 500-5 is sleeved on the rubber body. By sleeving the spring ring 500-5 on the rubber body, the sealing effect of the water seal structure 500 can be enhanced.

[0082] Preferably, in this embodiment, the coil spring 500-5 is hidden in the embedding groove, which can prevent the coil spring 500-5 from contacting the washing water. Thus, rusting of the coil spring 500-5 can be avoided, and the stability of the effect of the water seal structure 500 can be improved.

[0083] As Figure 2 and Figure 3 shown, in some possible embodiments, the rubber body includes a rubber body main body and a sealing lip 500-4 provided on the inner circumference of the rubber body main body. The rubber body main body includes a first extension portion 500-1 and a second extension portion 500-2.

The outer diameter of the first extension portion 500-1 is greater than or equal to the groove wall of the embedding groove, and the inner diameter of the first extension portion 500-1 is greater than the inner diameter of the installation groove 100-1. The extending direction of the second extension portion 500-2 is substantially perpendicular to the extending direction 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 be arranged to extend obliquely downward along the direction close to the axis of the water-stirring member 200, or may be arranged to extend obliquely upward along the direction close to the axis of the water-stirring member 200.

[0085] Preferably, the second extension portion 500-2 extends along the radial direction of the water-stirring member 200.

[0086] 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.

[0094] In this embodiment, the inner diameter of the spring coil 500-5 is less than or equal to the diameter of the lower end of the support column 210, so that the sealing lip 500-4 is hoop-shaped on the support column 210, and at the same time, the spring coil 500-5 can be prevented from contacting the washing water.

[0095] Preferably, in this embodiment, the water seal structure 500 further includes a skeleton 500-3, and the skeleton 500-3 is located inside the rubber body main body, and its extending direction is basically the same as the extending direction of the rubber body main body. The "basically the same" may mean that the extending direction of the skeleton 500-3 is the same as the extending direction of the rubber body main body, or there may be a slight deviation between the extending direction of the skeleton 500-3 and the extending direction of the rubber body main body.

[0096] In this embodiment, by using the setting method of the cooperation between the skeleton 500-3 and the rubber body, by embedding the skeleton 500-3 inside the rubber body, the shape and position of the first extension portion 500-1 and the second extension portion 500-2 of the rubber body can be shaped and supported, so that the strength of the rubber body is higher.

[0097] Specifically, the skeleton 500-3 is made of a hard material, and the skeleton 500-3 is injection-molded inside the rubber body and is arranged in the middle of the first extension portion 500-1 and the second extension portion 500-2.

[0098] Preferably, the skeleton 500-3 is arranged inside the rubber body main body, and both ends of the skeleton 500-3 extend into the first extension portion 500-1 and the second extension portion 500-2 respectively from the corners of the first extension portion 500-1 and the second extension portion 500-2.

[0099] As Figure 4 shown, in some other possible embodiments, the rubber body includes a rubber body main body and a sealing lip 500-4 arranged on the inner circumference of the rubber body main body.

[0100] In this embodiment, the shape of the rubber body main body is substantially the same as that of the embedding groove. The rubber body main body includes a first rubber section 500-8 and a second rubber section 500-9 with gradually decreasing outer diameters from top to bottom, and the first rubber section 500-8 and the second rubber section 500-9 are integrally formed.

[0101] There is an elastic abutment between the outer periphery of the first rubber section 500-8 and the groove wall of the embedding groove, and / or, there is an adhesion between the outer periphery of the first rubber section 500-8 and the groove wall of the embedding groove. The spring ring 500-5 is sleeved on the outer periphery of the second rubber section 500-9. Thus, it can be avoided that the washing water contacts the spring ring 500-5.

[0102] Preferably, in this embodiment, the lower end of the rubber body main body abuts against the bottom of the embedding groove, and the upper end of the rubber body main body is substantially flush with the inner surface of the barrel bottom. Preferably, the upper end surface of the rubber body main body is flush with the inner surface of the barrel bottom of the washing barrel 100.

[0103] Preferably, in this embodiment, an annular groove is provided on the outer periphery of the second rubber section 500-9, and the spring ring 500-5 is arranged in the annular groove. Thus, it can be avoided that the spring ring 500-5 disengages from the second rubber section 500-9.

[0104] and / or, the lower end of the outer periphery of the second rubber section 500-9 bulges outward in a direction away from the water stirring member 200, for limiting the axial position of the spring ring 500-5 to avoid the spring ring 500-5 disengaging from the second rubber section 500-9.

[0105] 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 section 500-8, and the second sealing lip 500-7 is arranged on the inner periphery of the second rubber section 500-9. The water seal structure 500 elastically abuts 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.

[0106] Specifically, the first sealing lip 500-6 is arranged on the inner periphery of the first rubber section 500-8 and extends obliquely upward along the inner periphery of the first rubber section 500-8 in a direction close to the axis of the water stirring member 200; the first sealing lip 500-6 has at least two turns and is arranged at intervals along the axis of the first rubber section 500-8.

[0107] Preferably, in this embodiment, the inner diameter of the first rubber section 500-8 is larger than that of the second rubber section 500-9. A step is formed between the inner walls of the first rubber section 500-8 and the second rubber section 500-9. The lowermost first sealing lip 500-6 is arranged at the junction of the inner circumferences of the first rubber section 500-8 and the second rubber section 500-9, and the top of the uppermost first sealing lip 500-6 is flush with the upper end face of the rubber body main body.

[0108] Specifically, in this embodiment, the first sealing lip 500-6 is provided with two circles, arranged along the axial direction of the first rubber section 500-8. The top of the upper first sealing lip 500-6 is flush with the upper end face of the rubber body main body. The lower end face of this first sealing lip 500-6 extends obliquely upward from the inner circumference of the first rubber section 500-8 along the direction close to the axis of the water stirring member 200. The thickness of the upper first sealing lip 500-6 gradually increases along the direction away from the axis of the water stirring member 200.

[0109] The lower first sealing lip 500-6 extends obliquely upward from the junction of the inner circumferences of the first rubber section 500-8 and the second rubber section 500-9 along the direction close to the axis of the water stirring member 200. The lower end of the root of the lower first sealing lip 500-6 is connected to the upper end of the inner circumference of the second rubber section 500-9, and the upper end of the root of the lower first sealing lip 500-6 is connected to a position on the inner circumference of the first rubber section 500-8 close to its lower end. That is, the lower first sealing lip 500-6 extends upward and in the direction close to the axis of the water stirring member 200 from the corner of the inner wall of the first rubber section 500-8 and the inner wall of the second rubber section 500-9.

[0110] Preferably, in this embodiment, a third sealing lip 500-10 is further included. The third sealing lip 500-10 is arranged between the two first sealing lips 500-6. Specifically, a third sealing lip 500-10 extending downward is provided at the root of the upper first sealing lip 500-6, and the end of the third sealing lip 500-10 abuts against the middle of the lower first sealing lip 500-6.

[0111] 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 and bends away from the circumference of the water stirring member 200 from the middle of the upper first sealing lip 500-6. The end of the side 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 and obliquely in the direction close to the axis of the water stirring member 200 from the root of the upper first sealing lip 500-6.

[0112] 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. There may be abutment between the third sealing lip 500-10 and the first sealing lip 500-6 located below, or there may be a certain distance therebetween.

[0113] In this embodiment, the arrangement 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, and assist the first sealing lip 500-6 located below to rebound towards the direction close to the axis of the water stirring member 200, so as to improve the sealing effect.

[0114] In this embodiment, the axial section of the first sealing lip 500-6 located below is a long rectangular shape.

The second sealing lip 500-7 is serrated, and the axial section of the second sealing lip 500-7 is a triangular shape protruding towards the direction close to the axis of the water stirring member 200.

[0116] Preferably, the second sealing lip 500-7 is arranged in at least two continuous turns along the axial direction of the second rubber section 500-9.

[0119] Further preferably, the upper end surface of the first rubber section 500-8 is set as a horizontal surface extending along the radial direction of the water stirring member 200.

[0120] Embodiment Two

[0121] As Figures 5 to 10As shown, in an embodiment of the present invention, a washing device is introduced, the washing device includes a washing tub assembly, the washing tub assembly includes a washing tub 100 and a water stirring member 200 installed on the washing tub 100. When the washing device is working, the washing water in the washing tub 100 is driven to rotate by the rotation of the water stirring member 200, so as to wash the clothes in the washing tub 100.

[0122] 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] The washing device further comprises a driving device, which is in driving connection with the washing tub 100 and the water stirring member 200. Specifically, the output shaft of the driving device is respectively in driving connection with the stirring shaft 300 and the dehydrating shaft. The stirring shaft 300 is connected to the water stirring member 200 and is relatively fixed, and is used to drive the water stirring member 200 to rotate. The dehydrating shaft is fixed to the bottom of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0125] The water stirring member 200 of the existing washing equipment is usually a flat circular impeller, and 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.

[0126] In this embodiment, the water stirring member 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 portion 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.

[0127] 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.

[0128] The water stirring member 200 is assembled with the stirring shaft 300 via the assembly portion 210 - 1 .

[0129] In this embodiment, the assembly part of the water-stirring member is sleeved on the upper end of the stirring shaft. The assembly part is key-connected to the stirring shaft. Specifically, the assembly part and the stirring shaft are circumferentially positioned by splines. Preferably, the assembly part of the water-stirring member and the stirring shaft are axially positioned by a clamping structure or screws.

[0130] In this embodiment, the assembly part 210-1 corresponds to the installation through-hole in the middle of the bottom of the barrel. The diameter of the assembly part is larger than the diameter of the stirring shaft. Preferably, an installation groove 100-1 is provided on the inner surface of the bottom of the washing barrel 100. A connecting part 215 that is rotatably inserted into the installation groove 100-1 is provided at the lower end of the assembly part 210-1. The radial dimension of the connecting part 215 is greater than or equal to the radial dimension of the part of the assembly part 210-1 between the connecting part 215 and the water-stirring part, and less than the radial dimension of any horizontal cross-section of the water-stirring part.

[0131] In this embodiment, the installation groove 100-1 is arranged around the stirring shaft 300. The installation through-hole is provided at the bottom of the installation groove 100-1. The stirring shaft passes through the installation groove 100-1 and extends into the washing barrel 100. The assembly part of the water-stirring member is sleeved on the stirring shaft 300. The diameter of the connecting part 215 at the bottom of the assembly part 210-1 is adapted to the diameter of the installation groove 100-1. A rotational pair is formed between the outer edge of the connecting part 215 and the groove wall of the installation groove 100-1.

[0132] The connecting part 215 is cylindrical. The assembly part 210-1 between the connecting part 215 and the water-stirring part can be columnar. It can be columnar with a gradually increasing diameter from top to bottom, can be columnar with a gradually decreasing diameter from top to bottom, can be cylindrical, or can be prismatic, as long as it is ensured that the clothes in the washing barrel can contact the part of the assembly part between the connecting part and the water-stirring member.

[0133] In this embodiment, even if the clearance area between the water-stirring member 200 and the bottom of the barrel is extremely small, there is still a certain possibility of dirt accumulation. Since the space in the clearance is relatively narrow and it is inconvenient for the user to operate, the user usually needs to remove the agitator to clean the dirt in the clearance. Existing washing devices usually install the water-stirring member 200 on the stirring shaft 300 of the washing device through screws 210-7, and this structure is not conducive to the user to disassemble and assemble the water-stirring member 200.

[0134] In this embodiment, an installation structure of the water-stirring member 200 is also introduced. This installation structure is applicable to the water-stirring member 200 with a large axial length. The water-stirring member with a large axial length can specifically be a stirring column, a stirring rod, a stirring bar, etc.

[0135] Such as Figure 5As shown in the figure, in this embodiment, the mounting structure is arranged between the assembly part 210-1 and the stirring shaft 300 of the washing device, and is used to realize the axial positioning between the water stirring member 200 and the stirring shaft 300.

[0136] As Figure 6 shown, the mounting 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, at least part of the insert 401 is inserted into the assembly part 210-1, and the locking assembly in the assembly part 210-1 locks the insert 401 along the axis of the water stirring member 200, realizing the axial positioning between the water stirring member 200 and the stirring shaft 300.

[0137] Specifically, the locking assembly includes a positioning cavity 402 and a limiting member 403, and the positioning cavity 402 and the limiting member 403 are coaxially arranged. An installation cavity 210-2 is arranged in the assembly part 210-1, and the positioning cavity 402 and the limiting member 403 are arranged in the installation cavity 210-2.

[0138] 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 part 210-1 and inserted into the limiting member 403. The positioning cavity 402 and the limiting member 403 approach each other and can lock the insert 401, and the positioning cavity 402 and the limiting member 403 move away from each other and can unlock the insert 401.

[0139] In this embodiment, the insert 401 is columnar, and the insert 401 can be coaxially arranged at the upper end of the stirring shaft 300 by any feasible means such as welding, bonding, forming, and threaded connection. A limiting groove is arranged on the insert 401, and the limiting groove is arranged around the circumferential wall of the insert 401; the limiting member 403 includes a limiting cavity 4031 and a clamping member 4032. A limiting hole 4033 is opened on the side wall of the limiting cavity 4031, and 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 moving in the radial direction of the insert 401; at least part of the limiting member 403 is inserted into the positioning cavity 402, and the diameter of the positioning cavity 402 gradually increases in the direction in which the limiting member 403 comes out, and the inner wall of the positioning cavity 402 limits the clamping member 4032 in the limiting groove.

[0140] In this embodiment, the positioning cavity 402 and the stopper 403 have a tendency 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 stopper 403 to separate the positioning cavity 402 from the stopper 403. Under the action of the insert 401, the clamping member 4032 moves along the stopper hole 4033 in a direction away from the axis of the water stirring member 200. Under the stopper action of the positioning cavity 402, the clamping member 4032 will not completely disengage from the stopper hole 4033. At this time, the insert 401 can enter the stopper 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 towards 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 clamped 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.

[0141] Preferably, in this embodiment, the inner wall of the positioning cavity 402 is configured as a frustum surface that is inclined in a direction away from the axis of the water stirring member 200 along the direction in which the stopper 403 escapes.

[0142] Preferably, in this embodiment, the limiting groove extends along the circumferential direction of the insert 401, and the limiting groove is configured such that the groove depth gradually increases 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 of the groove bottom of the limiting groove to ensure the locking effect of the clamping member 4032 on the insert 401, thereby preventing the water stirring member 200 from axial shaking when working.

[0143] Preferably, Figure 7 As shown, 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 of which the diameter gradually increases in the direction of escaping the positioning cavity 402, and the inclination angle of the side wall of the limiting cavity 4031 in the direction of escaping the positioning cavity 402 away from the axis of the water stirring member 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 away from the axis of the water stirring member 200.

[0144] Preferably, Figures 7 to 9 As shown, the limiting holes 4033 are provided with a plurality of holes evenly arranged along the circumference of the limiting cavity 4031 , and each limiting hole 4033 is provided with a clamping member 4032 , and the clamping member 4032 is set to be a spherical shape that matches the shape of the limiting hole 4033 .

[0145] Preferably, three limiting holes 4033 are provided.

[0146] A through hole communicating with the installation cavity 210-2 is formed at the bottom of the assembly part 210-1, and the through hole is adapted to the insert 401. Preferably, the aperture of the lower end of the through hole gradually increases from top to bottom, improving the smoothness of the insertion of the insert 401.

[0147] The top of the insert 401 preferably has a round head design, and the clamping member 4032 also preferably has a spherical design, 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 is more likely to fall into the limiting groove of the insert 401.

[0148] 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. An unlocking assembly for driving the limiting cavity 4031 and the limiting member 403 to separate from each other to unlock the insert 401 is further 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.

[0149] The unlocking assembly is arranged at the part of the assembly part 210-1 between the water stirring part and the inner surface of the barrel bottom, which is convenient for the user to operate the unlocking assembly.

[0150] Specifically, in this embodiment, one of the positioning cavity 402 and the limiting member 403 is fixed to the assembly part 210-1, and the other can slide along the axial direction of the water stirring member 200.

[0151] In some possible embodiments, the limiting member 403 is coaxially fixed to the inner wall of the bottom of the installation cavity 210-2, the positioning cavity 402 is coaxially arranged above the limiting member 403, the opening of the positioning cavity 402 faces downward, the diameter of the positioning cavity 402 gradually increases from top to bottom, and the unlocking assembly is used to drive the positioning cavity 402 to move axially.

[0152] The insert 401 is inserted into the installation cavity 210-2 from the bottom of the assembly part 210-1. The upper end of the insert 401 abuts against the clamping member 4032 in the limiting 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 far from the water stirring member 200 abuts against the inner wall of the positioning cavity 402. Since the positioning cavity 402 has a tendency to move towards the limiting member 403, the insert 401 cannot be inserted further.

[0153] 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 of the positioning cavity 402 at the contact with the clamping member 4032 increases. The clamping member 4032 moves in a direction away from the axis of the water stirring member 200 under the extrusion of the insert 401. At this time, the insert 401 can continue to be inserted.

[0154] As the insert 401 is inserted, when the clamping member 4032 enters the limiting groove, the positioning cavity 402 moves downward. One end of the clamping member 4032 close to the axis of the water stirring member 200 abuts against the bottom of the limiting groove, and the other end of the clamping member 4032 away from the axis of the water stirring member 200 abuts against the inner wall of the positioning cavity 402, realizing the axial positioning of the insert 401.

[0155] In this embodiment, the unlocking component includes a driving part 404 and a driven part 405. The driving part 404 is arranged on the side wall of the assembling part 210-1, and the driven part 405 is arranged on the positioning cavity 402 and is in transmission cooperation with the driving part 404.

[0156] Specifically, the driven part 405 includes a hollow limiting column 4051 arranged on the positioning cavity 402 and an extension plate 4052 extending radially from the outer wall of the hollow limiting column 4051 in a direction away from the axis of the water stirring member 200. The hollow limiting column 4051 extends upward from the top of the positioning cavity 402 and is integrally connected with the positioning cavity 402. The inner diameter of the hollow limiting column 4051 is adapted to the diameter of the insert 401. The extension plate 4052 abuts against the driving part 404 through an inclined surface that inclines downward and toward the axis of the water stirring member 200. When the driving part 404 moves in a direction toward the axis of the water stirring member 200, the driving part 404 squeezes the end of the extension plate 4052 to push the positioning cavity 402 upward.

[0157] As Figures 6 to 10 As shown, in some 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 caliber of the positioning cavity 402 gradually increases from bottom to top. The limiting member 403 is arranged above the positioning cavity 402, and at least part of the lower end of the limiting member 403 is inserted into the positioning cavity 402. The unlocking component is used to drive the limiting member 403 to move upward.

[0158] The insert 401 is inserted into the installation cavity 210-2 from the bottom of the self-assembly part 210-1. The upper end of the insert 401 abuts against the clamping part 4032 in the limiting part 403, pushing the limiting part 403 to move upward. Since the diameter of the positioning cavity 402 gradually increases from bottom to top, when the insert 401 pushes the limiting part 403 to move upward, the insert 401 will be pushed to move away from the axis of the water-stirring member 200, enabling the insert 401 to smoothly enter the limiting part 403. As the insert 401 is inserted, when the clamping part 4032 enters the limiting groove, the limiting part 403 moves downward. One end of the clamping part 4032 close to the axis of the water-stirring member 200 abuts against the bottom of the limiting groove, and one end of the clamping part 4032 away from the axis of the water-stirring member 200 abuts against the inner wall of the positioning cavity 402, realizing the axial positioning of the insert 401.

[0159] In this embodiment, the driven part 405 of the unlocking assembly is arranged on the limiting part 403. Specifically, it is arranged at one end of the limiting part 403 away from the positioning cavity 402. The hollow limiting column 4051 of the driven part 405 extends upward from the top of the limiting part 403. The extension plate 4052 of the driven part 405 extends radially away from the axis of the water-stirring member 200 from the outer wall of the hollow limiting column 4051 and abuts against the inner edge of the driving part 404 through an inclined surface that slopes away from the axis of the water-stirring member 200 from bottom to top. When the driving part 404 moves toward the axis of the water-stirring member 200, the driving part 404 squeezes the end of the extension plate 4052, pushing the limiting part 403 to move upward.

[0160] As Figure 7 and Figure 10 shown, in this embodiment, the driving part 404 is columnar. One 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 axis of the water-stirring member 200 and abuts against one end of the extension plate 4052 away from the axis of the water-stirring member 200.

[0161] Preferably, one end of the abutting part 4041 close to the axis of the water-stirring member 200 is set as an inclined surface that fits the end of the extension plate 4052.

[0162] Preferably, in this embodiment, a first guiding groove 4042 is provided at one end of the abutting portion 4041 close to the axis of the water stirring member 200. The end of the extension plate 4052 is inserted into the first guiding groove 4042 and abuts against the bottom of the first guiding groove 4042. The end of the extension plate 4052 is provided with an inclined surface that slopes upward and away from the axis of the water stirring member 200 from bottom to top, and the bottom of the first guiding groove 4042 fits against the end of the driven portion 405. In this embodiment, the provision of the first guiding groove 4042 can improve the guiding effect on the movement of the driven portion 405 and achieve circumferential limitation of the driven portion 405.

[0163] Preferably, in this embodiment, an avoidance groove 4043 for avoiding the upper end of the extension plate 4052 is provided on the driving portion 404 above the abutting portion 4041. Thus, when the driving portion 404 moves in the direction close to the axis of the water stirring member 200, the driven portion 405 moves upward under the push of the driving portion 404, and the upper end of the 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 interference with the driving portion 404, which can ensure the moving distance of the driving portion 404 moving in the direction close to the axis of the water stirring member 200 and improve the compactness of the cooperation structure between the driving portion 404 and the driven portion 405.

[0164] Preferably, as Figure 8 shown, a guiding sleeve 407 is further provided in the installation cavity 210-2. The guiding sleeve 407 extends downward from the inner wall of the top of the installation cavity 210-2 and is sleeved on the outer periphery of the hollow limiting column 4051; a second guiding groove 4071 for accommodating the extension plate 4052 is provided on the guiding sleeve 407 and extends upward from the lower end of the guiding sleeve 407.

Specifically, the first elastic member is a compression spring. The first elastic member is sleeved on the outer periphery of the guiding sleeve 407. One end of the first elastic member abuts against the inner wall of the top of the installation cavity 210-2, and the other end of the first elastic member abuts against the extension plate 4052. The first elastic member has a certain amount of compression, so that the limiting member 403 and the positioning cavity 402 approach each other to lock the inserted member 401 inserted therein.

[0166] In this embodiment, a guiding hole 406 is provided on the side wall of the assembling part 210-1, which communicates the installation cavity 210-2 with the outside of the assembling part 210-1 and is used to accommodate the driving part 404. The guiding hole 406 extends along the radial direction of the water-stirring member 200 and is adapted to the shape of the driving part 404. The driving part 404 is arranged in the guiding hole 406 and slides along the guiding hole 406 to drive the driven part 405 to move upward.

Two extending plates 4052 are arranged on the hollow limiting column 4051, which respectively correspond to and abut against the two driving parts 404. A second elastic member for driving the two driving parts 404 to move away from each other is arranged between the two opposite driving parts 404.

[0169] In some other possible embodiments, a rubber connecting wall is arranged between the inner wall of the guiding hole 406 and the driving part 404 to seal the gap between the two and to drive the driving part 404 to rebound. Specifically, the rubber connecting wall extends along the circumferential direction of the driving part 404. One end of the rubber connecting wall is connected to the driving part 404, and the other end is connected to the side wall of the installation cavity 210-2.

In the height direction, the side surface of the conical water-stirring member 200 is a curved surface. An inclination angle is formed between the side surface of the water-stirring member 200 and the bottom surface of the washing tub 100. The barrel wall of the washing tub 100 is vertically arranged. As the height of the support column 210 increases, the distance between the side surface of the water-stirring member 200 and the barrel wall of the washing tub 100 gradually decreases, and at the same time, the distance between the side surface of the water-stirring member 200 and the bottom surface of the washing tub 100 gradually increases.

The first part of the support column 210 is the assembly part 210-1, and the second part of the support column 210 extends upward from the top of the assembly part 210-1. The second part of the support column 210 corresponds to the water stirring part of the water stirring member 200, and water stirring ribs 220 are arranged on the outer peripheral wall of the second part of the support column 210.

[0174] In this embodiment, the assembly part 210-1 of the water stirring member 200 includes an outer cover and a mounting plate that are buckled together to form a mounting cavity 210-2.

[0175] In this embodiment, the mounting plate constitutes the connecting part 215 of the assembly part 210-1. The side wall of the mounting cavity 210-2 constitutes a part between the water stirring part and the bottom of the tub. The outer peripheral wall of this part is in contact with the clothes in the washing tub 100.

[0176] In this embodiment, the water stirring part is formed on the outer cover. A spline shaft for key connection with the stirring shaft 300 is arranged at the bottom of the mounting plate. The water stirring member 200 is circumferentially limited and connected with the stirring shaft 300 through the spline shaft.

The spline groove 210-6 at least partially sleeves the end of the stirring shaft 300, and the inner peripheral wall of the spline groove 210-6 cooperates with the splines on the outer peripheral wall of the upper end of the stirring shaft 300 to realize the circumferential positioning between the water stirring member 200 and the stirring shaft 300.

[0177] In this embodiment, the diameter of the mounting plate is greater than or equal to the outer diameter of the mounting cavity 210-2. An installation groove 100-1 is arranged on the bottom of the washing tub 100. At least a part of the lower end of the mounting plate is inserted into the installation groove 100-1, and a water seal structure 500 is arranged between the notch of the installation groove 100-1 and the mounting plate.

[0179] Embodiment III

[0180] As Figures 11 to 14 shown, in the embodiment of the present invention, a washing device is introduced. The washing device includes a washing tub 100 and a water stirring member 200 installed on the washing tub 100. When the washing device works, the rotation of the water stirring member 200 drives the washing water in the washing tub 100 to rotate, so as to realize the washing of the clothes in the washing tub 100.

[0181] In this embodiment, the washing tub 100 is a tub without holes.

[0182] 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 likely to accumulate in the gap between the bottom of the water stirring member 200 and the bottom of the tub. The area in this gap does not contact the clothes. Therefore, the impurities in the gap are in a state of long-term accumulation, and they cannot be effectively cleaned simply by flushing, which is easy to breed bacteria and cause pollution to the clothes with the washing water.

[0183] 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 the washing water from entering the gap between the water stirring member 200 and the bottom of the washing tub 100. Thus, it is avoided that dirt, lint and other impurities dropped from the clothes enter the gap between the water stirring member 200 and the bottom of the tub and accumulate, improving the cleanliness of the space in the washing tub 100 that contacts the washing water, and thus improving the washing effect on the clothes.

[0184] The water seal structure 500 is at least provided at one end where the gap between the water stirring member 200 and the bottom of the tub communicates with the washing space inside the washing tub 100.

[0227] Such as Figure 15 AndFigure 16 As shown in the figure, this embodiment provides a washing tub assembly of a washing device and a washing device having the washing tub assembly. In this embodiment, below the position where the radius of the water stirring member 200 is the largest, the distance between the side wall of the support column 210 and the tub wall of the washing tub 100 decreases as the height increases.

[0228] It should be noted that in the embodiments of the present invention, the position where the radius of the water stirring member 200 is the largest refers to the position where the radius dimension of the horizontal cross-section of the water stirring member 200 is the largest. The radius dimension of the horizontal cross-section of the water stirring member 200 means that the water stirring member 200 is sectioned along the horizontal direction, and the distance from the point farthest from the rotation center on the obtained horizontal cross-section to the rotation center.

[0229] Specifically, if the horizontal cross-section of the water stirring member 200 is circular, then the radius is the radius R1 of the circular cross-section. If the horizontal cross-section of the water stirring member 200 is non-circular, then the radius is the distance R2 from the point farthest from the rotation center on the cross-section to the rotation center.

[0230] In this embodiment, water stirring ribs 220 are provided on the side wall of the support column 210. The dimension of the water stirring ribs 220 along the radial direction of the washing tub 100 may remain constant as the height increases, or may gradually or stepwise change. By the distance between the side wall of the support column 210 and the tub wall of the washing tub 100 decreasing as the height increases, the distance between the side surface of the water stirring member 200 and the tub wall of the washing tub 100 shows a trend of decreasing as the height increases.

[0231] 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 point of the water stirring ribs 220 from the axis on the horizontal cross-section to the central axis.

[0232] In another specific embodiment, the water stirring ribs extend spirally along the side wall of the support column. At this time, the horizontal cross-section of the water stirring member 200 may not form a regular geometric figure, but the radius of the horizontal cross-section of the water stirring member 200 is still the distance from the farthest point of the water stirring ribs from the axis on the cross-section to the central axis.

[0233] In this embodiment, the clothes can also be washed in the space jointly formed by the bottom of the washing tub 100, the side wall of the support column 210, and the tub wall of the washing tub 100.

[0234] In the specific solution of this embodiment, the support column 210 includes a first extension section 211 and a second extension section 212 that are arranged below and connected to each other at the maximum radius of the water-stirring member 200. Among them, the side wall of the first extension section 211 extends obliquely upward from the bottom of the washing tub 100 and gradually approaches the barrel wall of the washing tub 100. The side wall of the second extension section 212 extends outward and obliquely upward from the upper end of the first extension section 211 to the height where the maximum radius of the water-stirring member 200 is located, so that the clothes can be washed under the side wall of the second extension section 212 and move outward along the side wall of the second extension section 212.

[0235] More specifically, the side wall of the first extension section 211 extends along a straight line and is inclined outward at a small angle relative to the vertical direction. The angle between the side wall of the second extension section 212 and the vertical direction is larger than that between the side wall of the first extension section 211 and the vertical direction, and as the height increases, the angle between the side wall of the second extension section 212 and the vertical direction gradually increases, forming a curved surface that bends toward the axis.

[0236] In this embodiment, a water-stirring plate 230 is also provided at the upper end of the support column 210. Specifically, the upper end of the second extension section 212 is connected to the lower surface of the water-stirring plate 230. The support column 210 of the water-stirring member 200 has the above structure, effectively reducing the problem of cleaning dead corners where clothes cannot reach between the upper end of the support column 210 and the lower surface of the water-stirring plate 230.

[0237] 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 plate 230, so that the lower surface of the water-stirring plate 230 is completely covered by the upper end surface of the support column 210.

[0238] In the preferred solution of this embodiment, as Figure 16 shown, the upper surface of the water-stirring plate 230 is a curved surface with the middle area higher than the outer peripheral area, and 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 plate 230, the stirring portion 231 can stir the washing water above the water-stirring plate 230 as the water-stirring member 200 rotates, and can also rub the clothes located above the water-stirring plate 230, thereby enhancing the washing effect.

[0239] Furthermore, in this embodiment, the side wall of the second extension section 212 forms a first guiding surface 213 for guiding the clothes below it to move outward along the first guiding surface 213 during washing. The side wall of the first extension section 211 forms a second guiding surface 214 for guiding the clothes to rise along the second guiding surface 214 to the first guiding surface 213 during washing.

[0240] Specifically, when the washing device applying the washing tub assembly described in this embodiment is washing, the water-stirring member 200 rotates relative to the washing tub 100, causing the clothes to move from the bottom of the washing tub 100 towards the central area, then move upward along the first guiding surface 213 to the second guiding surface 214, move outward along the guidance of the second guiding surface 214, and then fall in the area near the wall of the washing tub 100, forming an annular path. On the one hand, it can strengthen the tumbling of the clothes in the tub, thereby improving the washing effect. On the other hand, it also reduces the probability of the clothes concentrating towards the center and getting entangled.

[0241] As a specific implementation manner of this embodiment, at the connection position of the first extension section 211 and the second extension section 212, the angles between the side walls of both and the vertical direction are the same. That is, the first guiding surface 213 and the second guiding surface 214 have the same inclination angle at the connection, achieving a smooth transition connection.

[0242] As another specific implementation manner, the inclination angle of the side wall of the second extension section 212 relative to the vertical direction at the lower end position is slightly higher than the inclination angle of the side wall of the first extension section 211 relative to the vertical direction, thereby forming an angle less than but close to 180° at the connection of the first guiding surface 213 and the second guiding surface 214. In this way, when the clothes move upward along the second guiding surface 214 to the first guiding surface 213, it can play a certain buffering role for the clothes and strengthen the tendency of the clothes to move outward in a tumbling manner.

[0243] In a further solution of this embodiment, the water-stirring ribs 220 have a certain extension length along the axial direction of the washing tub 100, extending from the side wall of the first extension section 211 to the side wall of the second extension section 212. A plurality of water-stirring ribs 220 are arranged at intervals along the circumferential direction of the support column 210, and the interval angle between two adjacent water-stirring ribs 220 enables the clothes to be washed in the interval area between two adjacent water-stirring ribs 220, and at the same time the clothes can contact the side wall of the first extension section 211, and thus move upward along the side wall of the first extension section 211, that is, the second guiding surface 214.

[0244] In this way, the areas of the side walls of the first extension section 211 and the second extension section 212 between two adjacent water-stirring ribs 220 can contact the clothes, and no dead corners that are prone to accumulating dirt will be generated.

[0245] Furthermore, in this embodiment, the dimension of the water-stirring rib 220 along the radial direction of the washing tub 100 first increases and then decreases from the lower end to the upper end.

[0246] As a specific implementation manner, the water stirring rib 220 is approximately spindle-shaped in a cross-section parallel to the radial direction of the washing tub 100. The outer peripheral edge of the water stirring rib 220 extends from bottom to top, and the included angle between the extending direction and the vertical direction gradually decreases, so that the outer peripheral edge of the water stirring member 200 forms a curve that bends towards the barrel wall of the washing tub 100. The upper end of the outer peripheral edge of the water stirring rib 220 coincides with the outer circumference of the water stirring disk 230.

[0247] With the above structure, the water stirring rib 220 can form the Coanda effect during washing, driving the water flow to flow along the outer peripheral edge of the water stirring rib 220, so that in the area near the axis of the washing tub 100, the water flow has a tendency to conform to the outer peripheral edge of the water stirring rib 220. As the height increases, the flowing direction of the water flow is closer to upward rather than flowing outward. In this way, the lifting force of the water flow on the clothes in the area near the axis can be enhanced, driving the clothes to move upward to the first guiding surface 213 and finally forming a circular path.

[0248] It can be understood that the clothes moving from the bottom of the barrel towards the central area can also be lifted along the outer peripheral edge of the water stirring rib 220 after contacting the water stirring rib 220. After moving to the position with the maximum radius of the water stirring member 200, they move outward under the action of inertia and centrifugal force and finally fall along the barrel wall of the washing tub 100 to the bottom of the barrel.

[0249] In the preferred solution of this embodiment, the water stirring member 200 is installed in the washing tub 100, and there is a certain interval between the lower end of the water stirring rib 220 and the bottom of the washing tub 100 to avoid cleaning dead corners between the water stirring rib 220 and the bottom of the barrel. Specifically, the lower end of the support column 210 has a connecting portion 215 that is rotatably inserted into the mounting groove 100-1 on the bottom of the barrel. The lower end of the water stirring rib 220 is at least flush with the upper end of the connecting portion 215, and preferably higher than the upper end of the connecting portion 215. The stirring shaft for driving the rotation of the water stirring member 200 is fixed by being inserted into the connecting portion 215 from the lower end.

[0250] More preferably, a fillet structure with a smooth transition 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 member 200 that are prone to accumulating dirt, ensuring the cleaning hygiene inside the washing tub 100 to the greatest extent.

[0251] Further preferably, there is a fillet transition between the outer peripheral edge of the water stirring rib 220 and the two side surfaces of the water stirring rib 220 to avoid sharp corner structures that may scratch and damage clothes.

[0252] It can be understood that the connecting part at the lower end of the support column can also be completely arranged inside the washing tub, and the stirring shaft passes through the installation groove 100-1 on the bottom of the washing tub and is inserted into the connecting part. By setting a certain interval between the lower end surface of the connecting part and the bottom of the washing tub, or setting the difference between the outer diameter and the inner diameter of the connecting part small enough, the outer surface of the connecting part (including the outer side wall and the possible lower end surface) and the area of the bottom of the washing tub located outside the installation groove 100-1 can contact the clothes, and the purpose of preventing cleaning dead corners can also be achieved.

[0253] As a specific implementation manner, the thickness of the water-stirring rib 220 in the circumferential direction gradually decreases along the radially outward direction, and along the axial direction, the thickness of the middle region of the water-stirring rib 220 is greater than the thickness of the upper and lower ends.

[0254] In this embodiment, the change in the distance between the side surface of the water-stirring member 200 and the barrel wall of the washing tub 100 is formed by the change in the cross-sectional dimension of the support column 210 itself. Similarly, a structure with a certain distance from the bottom of the washing tub 100 at the maximum radius can be formed, ensuring that the clothes can be washed below the maximum radius of the water-stirring member 200. At the same time, the side wall of the support column 210 forms a first guiding surface 213 and a second guiding surface 214 for guiding the movement of the clothes during washing, which can effectively drive the clothes to move along a circular path and flip below the maximum radius of the water-stirring member 200, with better washing effect and can prevent the clothes from tangling.

[0264] In this embodiment, the water stirring portion 240 is connected to a stirring shaft 300 that can rotatably pass through the bottom of the washing tub 100 through the assembly portion 210-1, so that the water stirring member 200 can rotate relative to the washing tub 100.
