Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a washing barrel assembly of a washing device and the washing device. Background Art

[0002] As a washing device for washing clothes, washing machines have been widely used in people's lives. Existing washing machines are divided into drum washing machines and pulsator washing machines, among which pulsator washing machines are popular with users due to their good cleaning effect.

[0003] A pulsator washing machine usually includes a washing inner barrel and a pulsator, and the pulsator is arranged at the bottom of the washing inner barrel. When the pulsator washing machine is working, the rotation of the pulsator drives the washing water in the inner barrel to rotate, so as to wash the clothes to be washed in the inner barrel. The existing pulsator is usually a flat circular pulsator. When washing, impurities such as dirt and lint on the clothes are easily accumulated in the gap between the bottom surface of the pulsator and the inner barrel. It is impossible to effectively clean them by simply flushing. In addition, most of the clothes are covered on the pulsator during washing, which easily causes the clothes to be entangled and worn, and increases the energy consumption of the motor. In addition, dirt and lint are easy to breed bacteria when they are in a humid environment for a long time, which brings a bad user experience. If you want to clean it thoroughly, you need to remove the pulsator and scrub the dirt in the gap. This operation is relatively complicated, which further deteriorates the user experience.

[0004] In the prior art, a stirring type washing machine is also proposed, which uses an agitator with a certain size along the axial direction of the washing inner barrel to replace the pulsator in the pulsator washing machine. Figure 1 As shown, the agitator 1 in the existing agitator washing machine is often in an "inverted T" shape, consisting of an axial agitator 2 and a radial agitator 3, wherein the radial agitator 3 is arranged at the bottom of the washing tub 4 and has a larger radial dimension, and the clothes Y can only be washed in the area above the radial agitator 3 in the tub, which still cannot solve the problem that the gap between the agitator 1 and the bottom of the tub is easy to hide dirt and is difficult to clean. Some other agitator washing machines directly install the columnar agitator rod on the impeller at the bottom of the tub, and dirt and bacteria are still easy to accumulate between the impeller and the bottom of the tub.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing barrel assembly and washing apparatus for a washing device. By setting the radius of the bottom end face of the water stirring member to be equal to or substantially equal to the radius of the mounting portion, and making the barrel bottom at the periphery of the mounting portion form a washing surface extending outward from the mounting portion to the inner peripheral wall of the washing barrel, the radius of the bottom end face of the water stirring member is sufficiently small, and a connection without an impeller between the water stirring member and the barrel bottom is achieved, so that most of the area of ​​the barrel bottom is exposed to form a washing surface in contact with clothes, so as to avoid the problem that dirt and grime are easily hidden between the stirring device and the barrel bottom of the existing washing device and are difficult to clean, and clothes can be prevented from covering the impeller during washing, so as to reduce the entanglement and wear of clothes and reduce the energy consumption of the motor.

[0014] Furthermore, the water-stirring rib has a certain extension length along the axial direction of the support column, the bottom end of the water-stirring rib is connected to the side wall of the assembly part located in the washing tub, and the position where the water-stirring rib is connected to the assembly part is separated from the bottom of the tub by the side wall of the assembly part; or, the bottom end of the water-stirring rib is connected to the bottom end of the side wall of the assembly part located in the washing tub.

[0015] Further, the side wall of the assembly part, the inner surface of the bottom of the barrel extending outward from the mounting part to the inner peripheral wall of the washing barrel, the water stirring ribs and the inner peripheral wall of the washing barrel form a washing space; or, the inner side surface of the bottom of the barrel extending outward from the mounting part to the inner peripheral wall of the washing barrel, the water stirring ribs and the inner peripheral wall of the washing barrel form a washing space;

[0016] Preferably, the topmost end of the water-stirring rib extends to the maximum radius of the water-stirring member, and the washing space is formed below the maximum radius of the water-stirring member.

[0017] Furthermore, the side wall of the assembly portion is parallel or substantially parallel to the inner circumferential wall of the washing tub, and the distance between the water stirring rib and the inner surface of the tub bottom gradually increases from the bottom end of the water stirring rib to the inner circumferential wall of the washing tub.

[0018] Furthermore, the water-stirring rib has an arc-shaped outer side surface convex outwardly relative to the axis of the support column, and the radial spacing between the arc-shaped outer side surface and the axis of the support column gradually increases from the bottom to the top starting from the bottom of the water-stirring rib.

This can avoid the problem that dirt and grime are easily hidden between the stirring device and the bottom of the barrel of the existing washing equipment, which is difficult to clean, and can prevent clothes from covering the impeller during washing, thereby reducing the entanglement and wear of clothes and reducing the energy consumption of the motor.

[0050] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0052] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

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

[0054] like Figure 2-18 As shown, an embodiment of the present invention provides a washing tub 100 assembly of a washing device, and a washing device having the washing tub 100 assembly. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing device with a clothes washing function. When the washing device is a washing machine, the washing machine is preferably a pulsator washing machine.

[0055] Specifically, the washing tub 100 assembly includes the washing tub 100 and the water stirring member 200 rotatably disposed inside the washing tub 100. The washing device also includes a driving device, which is transmission-connected to the washing tub 100 and the water stirring member 200.

[0056] More specifically, the output shaft of the driving device is respectively connected to the stirring shaft 300 and the dehydrating shaft. The stirring shaft 300 is connected to the water stirring member 200 and relatively fixed, and is used to drive the water stirring member 200 to rotate. The dehydrating shaft is fixed to the bottom 100-3 of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0057] During the washing process, the driving device drives the water stirring member 200 to rotate alone, or drives the water stirring member 200 and the washing tub 100 to rotate in opposite directions, so as to utilize the relative rotation trend between the water stirring member 200 and the washing tub 100 to stir the clothes C and the washing water in the tub, thereby achieving a cleaning effect on the clothes C. During the dehydration process, the driving device drives the water stirring member 200 and the washing tub 100 to rotate synchronously at a high speed, and utilizes centrifugal force to spin dry the clothes C in the tub.

[0058] However, when the lint and dirt shed from the clothes C during the washing process are mixed into the washing water, if there is a relatively narrow gap structure between the water stirring member 200 and the washing tub 100, these lint and dirt are easily hidden in the gap structure and are difficult to be taken out by the impact force of the water flow during the washing process, and the user needs to manually disassemble the water stirring member 200 for cleaning. If the user does not clean it for a long time, a large amount of dirt will accumulate in the gap between the water stirring member 200 and the washing tub 100, which is easy to breed bacteria, causing the problem of secondary contamination of the clothes C.

[0059] The present embodiment provides a washing tub 100 assembly of a washing device, and a washing device having the washing tub 100 assembly, which are used to solve the problem that there is a dead corner between the water stirring device and the washing tub 100 of the existing equipment, which is difficult to clean and can hide dirt.

[0060] Specifically, the washing barrel 100 assembly described in this embodiment includes a washing barrel 100, a water stirring member 200 and a stirring shaft 300 that drives the water stirring member 200 to rotate relative to the washing barrel 100. The barrel bottom 100-3 of the washing barrel 100 has a mounting portion 100-2 rotatably assembled with the stirring shaft 300. The stirring shaft 300 passes through the mounting portion 100-2 and is connected to the water stirring member 200. The bottom of the water stirring member 200 is arranged opposite to the mounting portion 100-2. The radius of the bottom end face of the water stirring member 200 is equal to or substantially equal to the radius of the mounting portion 100-2. The inner surface of the barrel bottom 100-3 extending outward from the mounting portion 100-2 to the inner circumferential wall of the washing barrel 100 is a washing surface 100-31 that can contact clothes.

[0061] The water-stirring member 200 and the washing tub 100 described in the present embodiment have the above-mentioned matching structure. Compared with the traditional pulsator washing machine or the stirring washing machine with a radial agitator, the radius of the bottom end face of the water-stirring member 200 of the present application is small enough to achieve a connection between the water-stirring member 200 and the tub bottom 100-3 without an impeller, so that the washing tub has no bottom disc-shaped stirring portion, thereby exposing most of the area of ​​the tub bottom 100-3 to form a contact surface with the clothes, which can avoid the problem of easy accumulation of dirt and grime between the stirring device and the tub bottom 100-3 of the existing washing equipment and difficulty in cleaning, and can prevent clothes from covering the impeller during washing, which can reduce entanglement and wear on clothes and reduce energy consumption of the motor.

[0062] The mounting portion 100-2 of the present application is for the stirring shaft 300 to pass through and connect with the water stirring member 200. Since the radius of the stirring shaft 300 is small enough, in order to adapt to the stirring shaft 300, the radius of the mounting portion 100-2 is also small enough. The radius of the bottom end face of the water stirring member 200 is set to be equal to or substantially equal to the radius of the mounting portion 100-2. Then, the radius of the bottom end face of the water stirring member 200 will be small enough. In the prior art, the radius of the impeller set on the barrel bottom 100-3 is much larger than the radius of the mounting portion 100-2. Therefore, it can be considered that the barrel bottom 100-3 of the present application has no impeller, and there is no impeller connection between the water stirring member 200 of the present application and the barrel bottom 100-3, so that most of the area of ​​the barrel bottom 100-3 is exposed to form a washing surface 100-31 that is in direct contact with the clothes, so that the washing surface 100-31 formed by the barrel bottom 100-3 is in contact with the clothes during washing, which can be distinguished from the direct contact between the clothes and the impeller during washing in the prior art.

[0063] It should be noted that the radii of the components involved in the present application are all radii along the radial direction of the washing barrel 100; the barrel bottom 100-3 includes a barrel bottom body, and the mounting portion is arranged on the barrel bottom body, rather than providing a component on the barrel bottom and the mounting portion is arranged on the component.

[0064] The radius of the bottom end surface of the water stirring member 200 is substantially equal to the radius of the mounting portion 100-2, including that the radius of the bottom end surface of the water stirring member 200 is slightly larger than the radius of the mounting portion 100-2, or that the radius of the bottom end surface of the water stirring member 200 is slightly smaller than the radius of the mounting portion 100-2;

[0065] Further, the mounting portion 100-2 is a mounting through hole 100-21 provided on the barrel bottom 100-3. The mounting through hole 100-21 may be circular, square, etc. The mounting through hole 100-21 passes through the barrel bottom 100-3. The water-stirring member 200 and the mounting through hole 100-21 are arranged relative to each other in the following manner: when the bottom end face of the water-stirring member 200 is equal to or greater than the radius of the mounting through hole 100-21, the bottom end face of the water-stirring member 200 is overlapped on the upper end face of the mounting through hole 100-21 and abuts against the upper end face of the mounting through hole 100-21; or, when the bottom end face of the water-stirring member 200 is smaller than the radius of the mounting through hole 100-21, the bottom end face of the water-stirring member 200 is inserted into the mounting through hole 100-21.

[0066] More specifically, the stirring shaft 300 extends from the mounting through hole 100-21 to the inside of the washing tub 100, and the stirring shaft 300 is coaxially arranged with the washing tub 100; the water stirring member 200 of the present application includes an assembly portion 210-1 coaxially arranged with the tub bottom 100-3 and a water stirring portion 240 arranged above the assembly portion 210-1, and the water stirring portion 240 is assembled with the stirring shaft 300 through the assembly portion 210-1;

[0067] The assembly part 210-1 of the water-stirring member 200 is sleeved on the upper end of the stirring shaft 300, and the assembly part 210-1 and the stirring shaft 300 are key-connected. The assembly part 210-1 and the stirring shaft 300 are circumferentially positioned by splines. Preferably, the assembly part 210-1 of the water-stirring member 200 and the stirring shaft 300 are axially positioned by a clamping structure or screws.

[0068] The assembly part 210-1 corresponds to the installation through hole 100-21 in the middle of the barrel bottom 100-3. The inner side of the barrel bottom 100-3 is provided with an installation groove 100-1. The lower end of the assembly part 210-1 can be rotatably inserted into the installation groove 100-1. The installation groove 100-1 is arranged around the stirring shaft 300. The installation through hole 100-21 is arranged on the bottom of the installation groove 100-1. The stirring shaft 300 passes through the installation groove 100-1 and extends to the inside of the washing barrel 100. The radius of the bottom of the assembly part 210-1 is adapted to the radius of the installation groove 100-1.

[0069] The washing surface 100-31 and the space above the washing surface 100-31 form a washing space, and the water stirring member 200 has a maximum radius at a certain distance from the washing surface 100-31, and the clothes can be washed in the washing space below the maximum radius of the water stirring member 200, or the clothes are guided from below the maximum radius of the water stirring member 200 to the washing space above for washing. The water stirring member 200 becomes smaller after the maximum radius, and the washing space below the maximum radius of the water stirring member 200 forms a first space 100a, and a second space 100b is formed between the maximum radius of the water stirring member and the minimum radius above.

[0070] The minimum radius above the maximum radius of the water stirring member 200 is at a certain distance from the barrel opening of the washing tub 100, and the washing space between the minimum radius above the maximum radius of the water stirring member 200 and the barrel opening forms a third space 100c;

[0071] When the water level in the washing tub is higher than a set water level, the water stirring member rotates to guide part of the clothes from the first space and the second space to the third space for washing.

[0072] At the lowest water level, the laundry may be washed in the first space 100a and the second space 100b, and at the highest water level, the laundry may be washed in the first space 100a, the second space 100b, and the third space 100c.

[0073] Specifically, the washing bucket 100 assembly of this embodiment is applied to washing equipment, such as Fig.16 As shown, when operating at a low water level W1 lower than the maximum radius Dmax of the water stirring member 200, the laundry moves along a reverse circular path in the water.

[0074] In detail, during the washing process, relative rotation occurs between the water stirring member 200 and the washing tub 100, and the clothes move along the path indicated by the arrow in the figure in the first space 100a below the maximum radius Dmax of the water stirring member 200, move toward the central area along the bottom 100-3 of the washing tub 100, and then are lifted to the bottom of the first guide surface 213 along the water stirring ribs 220, and then move toward the periphery along the first guide surface 213, and then fall to the bottom 100-3 in the area close to the wall of the washing tub 100, forming a circular motion.

[0075] like Fig.17 As shown, when a high water level W2 higher than the maximum radius Dmax of the water stirring member 200 is used, in an area lower than the maximum radius Dmax of the water stirring member 200, the clothes move in the water along the above-mentioned circular path; and in an area at a minimum radius higher than the maximum radius of the water stirring member 200, the clothes are close to moving circumferentially along the washing tub 100, that is, the clothes are washed in the third space 100c.

[0076] In detail, during the washing process, the water stirring member 200 and the washing tub 100 rotate relative to each other, and in the area below the maximum radius Dmax of the water stirring member 200, the movement path of the clothes is basically the same as the movement path under the low water level W1. In the area above the minimum radius Dmax of the water stirring member 200, the clothes move alternately forward and reverse along the circumference of the washing tub 100100 as the water stirring member 200 rotates alternately forward and reverse.

[0077] In the above scheme, when different washing water levels are used, the water stirring member 200 can drive the clothes in the barrel to move in different ways for washing, providing a more diverse selection of washing methods. Moreover, in the area below the maximum radius Dmax of the water stirring member 200, since the clothes move along a reverse circular path, on the one hand, the turning of the clothes can be strengthened, the washing effect can be enhanced, and on the other hand, the problem that the existing pulsator washing machine easily drives the clothes to gather toward the center, causing the clothes to be entangled, can be avoided. It should be noted that the upper end of the water stirring rib 220 is connected to the first guide surface 213, and the first guide surface 213 in the first embodiment can be formed on the water stirring rib 220.

[0078] In this embodiment, the water stirring component 200 includes an assembly portion 210-1 coaxially arranged with the barrel bottom 100-3 and a water stirring portion 240 arranged above the assembly portion 210-1. The stirring shaft 300 is inserted into the assembly portion 210-1 through the installation portion 100-2 and connected to the water stirring portion 240. The water stirring component 200 has a maximum radius at a certain distance from the inner surface of the washing barrel 100, and the radius of the assembly portion 210-1 is the minimum radius of the water stirring component 200 below the maximum radius of the water stirring component 200.

[0079] In this embodiment, the assembly part 210-1 of the present application is the assembly part 210-1, and the assembly part 210-1 may be cylindrical, and may be a cylindrical shape with a radius that changes from top to bottom, or may be a cylindrical shape with a constant radius from top to bottom; wherein the assembly part 210-1 has a cavity inside for inserting the stirring shaft 300;

[0080] It should be noted that the radius of the water stirring member 200 refers to the cross section of the water stirring member 200 taken along the horizontal direction (see Figure 4 ), the distance from the farthest point on the horizontal section to the center of rotation.

[0081] Specifically, if the cross section of the water stirring member 200 is Figure 5 If the cross section of the water stirring member 200 is Figures 6 to 11 For a non-circular shape as shown, the radius is the distance R from the farthest point on the cross section from the center of rotation to the center of rotation (i.e. the position marked with "×" in the figure).

[0082] Below the maximum radius of the water-stirring member 200, the radius of the assembly portion 210-1 is the minimum radius of the water-stirring member 200, so that the radius of the assembly portion 210-1 is small enough to achieve a non-pulsator connection between the water-stirring member 200 and the barrel bottom 100-3, thereby exposing most of the area of ​​the barrel bottom 100-3 to form a washing surface 100-31 that contacts the clothes.

[0083] In this embodiment, the water stirring portion 240 includes a support column 210 coaxial with the assembly portion 210-1 and a water stirring rib 220 protruding from the side wall of the support column 210. The maximum radius of the water stirring member 200 is arranged on the support column 210, and the radius of the support column 210 below the maximum radius of the water stirring member 200 is greater than or equal to the radius of the assembly portion 210-1.

[0084] In this embodiment, the support column 210 may be columnar, specifically, Figure 1-15 As shown, the support column 210 can be a column with a constant radius from bottom to top, and the radius of the support column 210 is set to be greater than or equal to the radius of the assembly part 210-1, so that the radius of the assembly part 210-1 can be small enough; preferably, the assembly part 210-1 and the support column 210 are integrally formed.

[0085] Specifically, the maximum radius of the water-stirring member 200 is located at the position of the water-stirring member 200 support column 210, including the maximum radius of the water-stirring member 200 being located at the top of the water-stirring member 200 support column 210; or, the maximum radius of the water-stirring member 200 is spaced from the top of the water-stirring member 200 support column 210.

[0086] As a specific implementation method, Figure 2,as well as Figure 12 to Figure 14 As shown, the water stirring member 200 has a unique maximum radius Dmax in the height direction. Further, at least below the maximum radius Dmax, as the height increases, the distance between the side of the water stirring member 200 and the inner peripheral wall of the washing tub 100 decreases as the height increases.

[0087] It should be noted that the unique maximum radius Dmax may refer to the water-stirring member 200 having the maximum radius Dmax at a specific height position, or may refer to the water-stirring member 200 having the maximum radius Dmax within a certain continuous height range.

[0088] In a first specific solution, the maximum radius Dmax 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.

[0089] In the second specific scheme, if Fig.12 As shown, the maximum radius Dmax of the water stirring member 200 is close to the top of the water stirring member 200, but is at a certain distance from the top of the water stirring member 200. Specifically, the upper side surface of the water stirring member 200 at the maximum radius Dmax is an upwardly convex curved surface, and the highest point of the curved surface forms the top of the water stirring member 200.

[0090] In the third specific scheme, if Fig.13 and Fig.14 As shown, the maximum radius Dmax of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0091] In a detailed scheme, Fig.13 As shown, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 changes continuously in the height direction. Specifically, as the height increases, the radius of the water stirring member 200 gradually increases from the bottom 100-3 of the washing tub 100 upward until the maximum radius Dmax is formed, and then the radius of the water stirring member 200 gradually decreases and finally reaches the top of the water stirring member 200.

[0092] In another detailed scheme, Fig.14As shown, the distance between the side of the water stirring member 200 and the barrel wall of the washing tub 100 has a sudden change at at least one height position. Specifically, as the height increases, the radius of the water stirring member 200 first gradually increases from the barrel bottom 100-3 of the washing tub 100 upwards, and when reaching a certain height, the radius suddenly increases to form the maximum radius Dmax, and then the radius of the water stirring member 200 remains constant within a certain height range, then suddenly decreases, and then continues to gradually decrease, and finally forms the top of the water stirring member 200. In this solution, the distance h from the maximum radius Dmax on the water stirring member 200 to the barrel bottom 100-3 of the washing tub 100 refers to the distance from the lowest height in the height range where the radius of the water stirring member 200 remains constant to the barrel bottom 100-3 of the washing tub 100.

[0093] The maximum radius of the water stirring member 200 is located at the position of the support column 210 of the water stirring member 200, and also includes the maximum radius of the support column 210 of the water stirring member 200 having a plurality of intervals distributed from top to bottom.

[0094] As another specific implementation, Fig.15 As shown, the water stirring member 200 has a plurality of spaced maximum radius points Dmax in the axial direction of the washing tub 100. Specifically, as the height increases, the radius of the water stirring member 200 increases and decreases alternately, each time increasing to the same radius size and then decreasing, thereby forming a plurality of spaced maximum radius points Dmax.

[0095] Furthermore, the present application sets the axial length of the assembly part 210-1 to be smaller than the axial length of the support column 210. If the above-mentioned axial direction is the axial direction of the washing barrel 100, the axial length of the assembly part 210-1 is much smaller than the axial length of the support column 210, which can reduce the axial thickness of the assembly part 210-1, so that a larger area of ​​the barrel bottom 100-3 can be exposed.

[0096] In this embodiment, the water-stirring rib 220 has a certain extension length along the axial direction of the support column 210, and the bottom end of the water-stirring rib 220 is connected to the assembly part 210-1 located in the washing barrel 100. The position where the water-stirring rib 220 is connected to the assembly part 210-1 is separated from the barrel bottom 100-3 by the side wall of the assembly part 210-1, which can prevent dirt and grime from being easily hidden between the water-stirring rib 220 and the barrel bottom 100-3, and make the bottom of the washing space formed by the side wall of the assembly part 210-1, the inner surface of the barrel bottom 100-3 extending outward from the inner circumferential wall of the washing barrel 100, and the water-stirring rib 220 and the inner circumferential wall of the washing barrel be large enough.

[0097] Alternatively, the bottom end of the water-stirring rib 220 is connected to the bottom end of the side wall of the assembly portion 210-1 located in the washing tub 100, so that the mounting portion 100-2 extends outward to the inner side surface of the barrel bottom 100-3 of the inner circumferential wall of the washing tub 100, the water-stirring rib 220 and the inner circumferential wall of the washing tub 100 form a washing space; when the assembly portion 210 is entirely in the washing tub, the bottom end of the water-stirring rib 220 is connected to the bottom end of the side wall of the assembly portion 210-1, and when the first part of the assembly portion 210 is in the washing tub, the bottom end of the water-stirring rib 220 is connected to the bottom end of at least part of the side wall of the assembly portion 210.

[0098] In this embodiment, the lower end of the water stirring rib 220 is spaced apart from the bottom 100-3 of the washing tub 100, and the top end of the water stirring rib 220 extends to the maximum radius of the water stirring member 200. Preferably, the top end of the water stirring rib 220 extends to the peripheral edge close to the maximum radius of the water stirring member 200. Specifically, the bottom of the support column 210 has an assembly portion 210-1 for connecting the stirring shaft 300, and the peripheral edge of the water stirring rib 220 extends upwardly from a certain distance from the upper end of the assembly portion 210-1 on the side wall of the support column 210, and the inclination angle remains constant or gradually changes, and finally extends to the height of the maximum radius Dmax of the water stirring member 200. There is no other structure extending radially along the washing tub 100 between the lower end of the water stirring rib 220 and the assembly portion 210-1, and the bottom 100-3 of the washing tub 100 will not be covered, ensuring that there is basically no area on the bottom 100-3 of the washing tub 100 that cannot contact the clothes.

[0099] The water stirring ribs 220 rotate in the washing tub 100 with the water stirring member 200, stirring the clothes C and the water flow in the tub. The rotation of the water stirring member 200 can generate different water flow modes to drive the clothes C to move for washing, especially, below the maximum radius Dmax of the water stirring member 200, the clothes C move along a circular path in the formed washing space for washing. The above-mentioned circular path refers to the movement toward the center in the barrel bottom 100-3 area of ​​the washing tub 100, being lifted by the water stirring member 200 to the position close to the maximum radius Dmax of the water stirring member 200, and then falling after moving toward the periphery. That is, the clothes move toward the central area along the barrel bottom 100-3 of the washing tub 100, and are gathered, and are lifted to the position below the maximum radius Dmax along the side wall of the support column 210 or the outer peripheral edge of the water stirring ribs 220 in the central area, and then move toward the periphery, and then fall to the barrel bottom 100-3 in the area close to the barrel wall of the washing tub 100, forming a circular motion mode.

[0100] Furthermore, the protruding direction of the water stirring rib 220 on the side wall of the support column 210 coincides with the radial direction of the washing tub 100, or forms an angle 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 rotation direction, which can achieve an effective stirring effect.

[0101] More specifically, a plurality of water-stirring ribs 220 are arranged at intervals along the circumferential direction on the side wall of the support column 210, and the plurality of water-stirring ribs 220 are preferably arranged symmetrically with respect to the rotation axis. Clothes C can be washed in the interval area between two adjacent water-stirring ribs 220, thereby contacting the two side surfaces of the water-stirring ribs 220 and the area between the two water-stirring ribs 220 on the side wall of the support column 210, thereby avoiding the existence of cleaning dead corners on the side wall of the support column 210 where dirt is easily attached. At the same time, during washing, the clothes C moving toward the central area along the bottom 100-3 of the washing barrel 100 are lifted along the side wall of the support column 210 to below the maximum radius Dmax of the water-stirring member 200, and then move toward the periphery and fall, forming a circular path.

[0102] Below the maximum radius Dmax of the water stirring member 200, the side wall of the support column 210 is extended in the vertical direction or nearly in the vertical direction until it reaches the position where the maximum radius Dmax of the water stirring member 200 is located. The water stirring rib 220 protrudes from the side wall of the support column 210 and has a certain height along the axial direction of the washing tub 100. The radial dimension of the water stirring rib 220 along the washing tub 100 increases with the increase of the height, thereby forming a structure in which the distance between the side of the water stirring member 200 and the barrel wall of the washing tub 100 decreases with the increase of the height.

[0103] Specifically, the side wall of the assembly portion 210-1 is parallel or substantially parallel to the inner peripheral wall of the washing tub, and the distance between the water stirring rib 220 and the inner surface of the tub bottom 100-3 gradually increases from the bottom end of the water stirring rib 220 toward the inner peripheral wall of the washing tub. The water stirring rib 220 has an arc-shaped outer side surface that protrudes outward relative to the axis of the support column 210, and the radial distance between the arc-shaped outer side surface and the axis of the support column 210 gradually increases from the bottom to the top from the bottom end of the water stirring rib 220, further realizing that most of the area of ​​the tub bottom 100-3 is exposed; the arc-shaped outer side surface can reduce the wear on the clothes.

[0104] As a specific implementation, in this embodiment, the distance h between the maximum radius Dmax of the water stirring member 200 and the barrel bottom 100 - 3 is greater than 5 mm, thereby ensuring that the clothes C can be washed below the maximum radius Dmax.

[0105] Furthermore, in this embodiment, the depth of the washing tub 100 is H, and the distance h and the depth H of the washing tub 100 satisfy: h / H≥1%. Through a large number of tests conducted in advance, it is found that when the distance h and the depth H of the washing tub 100 satisfy the above proportional relationship, the effect of preventing dirt from accumulating between the water stirring member 200 and the washing tub 100 is the best.

[0106] In a further solution of this embodiment, there is also a certain distance in height between the maximum radius Dmax of the water-stirring component 200 and the barrel mouth of the washing barrel 100, so that the washing water level can be higher than the maximum radius Dmax of the water-stirring component 200, so that the clothes C can be washed above the position where the maximum radius Dmax of the water-stirring component 200 is located.

[0107] In the above scheme, the washing tub 100 can accommodate clothes C for washing both above and below the maximum radius Dmax of the water-stirring member 200. On the one hand, the volume of the washing tub 100 that can accommodate clothes C is increased. On the other hand, the outer surface of the water-stirring member 200 can basically contact the clothes C to be washed and generate friction with the clothes C. By increasing the surface area in contact with the clothes C, the washing effect can be enhanced.

[0108] For the solution in which the maximum radius Dmax of the water-stirring member 200 is located at or close to the top of the water-stirring member 200, as a specific implementation, Fig.12 As shown, the maximum radius Dmax of the water-stirring member 200 is formed by the upper end of the outer peripheral edge of the water-stirring rib 220 .

[0109] As another specific implementation, Figure 2 As shown, the water stirring member 200 further includes a water stirring plate 230, which is connected to the upper end of the support column 210, and the outer periphery of the water stirring plate 230 forms the maximum radius Dmax of the water stirring member 200. The upper end of the water stirring rib 220 is connected to the lower surface of the water stirring plate 230, so as to prevent the existence of a dead corner between the water stirring rib 220 and the water stirring plate 230 that cannot contact the clothes C and is easy to hide dirt.

[0110] Furthermore, the water stirring member 200 of the present embodiment forms a guide surface extending toward the periphery below the maximum radius Dmax, and during washing, the clothes C lifted to below the maximum radius Dmax of the water stirring member 200 move toward the periphery along the guide surface. More specifically, in the present embodiment, the guide surface includes the lower surface of the water stirring plate 230. Preferably, a smoothly transitioning curved surface is provided between the upper end of the side wall of the support column 210 and the lower surface of the water stirring plate 230. More preferably, a rounded transition is provided between the two side surfaces of the water stirring rib 220 and the lower surface of the water stirring plate 230. In this way, the dead corners on the water stirring member 200 that are difficult to clean are further reduced.

[0111] As a specific solution, in this embodiment, the upper end of the water stirring rib 220 is aligned with the outer periphery of the water stirring plate 230 away from the support column 210, so that the radial dimension of the water stirring rib 220 along the washing barrel 100 is maximized as much as possible, which can enhance the stirring force of the washing water and improve the washing effect.

[0112] When washing clothes C, the washing device having the washing tub 100 assembly described in this embodiment can drive the clothes C to move along a circular path below the maximum radius Dmax of the water stirring member 200 by controlling the water stirring member 200 to rotate relative to the washing tub 100 for washing.

[0113] Specifically, in the bottom area of ​​the washing tub 100, the stirring action of the water stirring member 200 on the water flow drives the water flow to generate a flow trend along the radial direction of the washing tub 100, and then drives the clothes C to move along the bottom 100-3 of the washing tub 100 toward the central area. The clothes C gathered toward the center contact the side of the water stirring member 200, and are lifted upward under the rotation of the water stirring member 200 until they move to the lower side of the maximum radius Dmax of the water stirring member 200. At the lower side of the maximum radius Dmax of the water stirring member 200, the trend of the water flow and the clothes C to continue to move upward is blocked, and then they move toward the periphery along the guide surface at the lower side of the maximum radius Dmax of the water stirring member 200, and finally fall back to the bottom 100-3 in the area close to the wall of the washing tub 100, or after contacting the wall of the washing tub 100, driven by gravity and the water flow.

[0114] In this embodiment, the water stirring member 200 installed in the washing tub 100 forms a maximum radius Dmax at a certain distance from the tub bottom 100-3, so that the clothes C can be washed below the maximum radius Dmax, so that most of the surface of the tub bottom 100-3 of the washing tub 100 is exposed in the washing water and can contact the washed clothes C. During the washing process, the clothes C can contact the tub bottom 100-3 of the washing tub 100 and the outer surface of the water stirring member 200 located below the maximum radius Dmax, generating friction, effectively avoiding the problem of a cleaning dead angle between the water stirring member 200 and the washing tub 100, which is easy to accumulate lint and dirt.

[0115] On the other hand, during the washing process, the water stirring member 200 can drive the clothes C to gather toward the center at the bottom of the barrel 100-3, then be lifted to a certain height, and then guide the clothes C to move toward the periphery and then fall, thereby moving along a reverse circular path around the water stirring member 200, which can both enhance the washing effect and prevent the clothes C from getting entangled.

[0116] Embodiment 2

[0117] like Figure 18-20As shown, this embodiment provides a washing tub 100 assembly of a washing device, and a washing device having the washing tub 100 assembly. The difference between the washing tub 100 assembly provided in this embodiment and the above-mentioned embodiment 1 is that: below the maximum radius Dmax of the water stirring member 200, the support column 210 can also be a columnar shape with a radius that changes from bottom to top, and the distance between the side wall of the support column 210 and the barrel wall of the washing tub 100 decreases with increasing height.

[0118] In this embodiment, the water-stirring member 200 includes an assembly portion 210-1 and a water-stirring portion 240 extending upward from the assembly portion 210-1. The assembly portion 210-1 is configured as a solid structure, and the water-stirring portion 240 is at least partially configured as a hollow structure. For example, the water-stirring portion 240 is a cavity configured from the top end axially toward the assembly portion 210-1.

[0119] Specifically, in this embodiment, the assembly part 210-1 is a solid column, which can increase the connection strength of the water stirring member 200. The water stirring part 240 has an integrally formed hollow structure, and the water stirring part 240 is formed on the top of the assembly part 210-1, and the assembly part 210-1 can also block the lower end of the hollow structure of the water stirring part 240.

[0120] As a specific embodiment, the water-stirring member 200 includes a support column 210, and a water-stirring rib 220 arranged on the side wall of the support column 210 and protruding along the radial direction or near radial direction of the support column away from the axis of the support column 210. The water-stirring rib 220 extends along the axial direction of the support column in the length direction, and extends in the width direction away from the peripheral direction of the support column. The water-stirring rib 220 can be arranged radially or deviate from the radial direction.

[0121] In this embodiment, the support column 210 includes an assembly portion 210-1 and a hollow column 210-8 coaxially connected to the upper portion of the assembly portion 210-1. The assembly portion 210-1 is a solid column, preferably a cylindrical body, and the hollow column 210-8 extends upward from the upper end surface of the assembly portion 210-1.

[0122] The water stirring portion 240 has a horizontal cross section with the largest radius at a certain height from the upper end of the assembly portion 210-1. A water stirring plate 230 is provided at the top of the support column 210. The maximum radius Rmax of the water stirring portion 240 is formed by the outer periphery of the water stirring plate 230. The top surface of the water stirring plate 230 is a curved surface convex upward. A cavity 210-9 similar to the outer shape of the support column 210 is formed inside the hollow column 210-8.

[0123] Preferably, the water stirring ribs 220 are also configured as hollow structures.

[0124] Further preferably, the inner space of the water stirring rib 220 is connected to the cavity 210 - 9 inside the hollow column 210 - 8 .

[0125] Further preferably, the lower end of the water-stirring rib 220 at least partially extends to the outer peripheral wall of the assembly portion 210 - 1 and is integrally formed with the assembly portion 210 - 1 , thereby further strengthening the strength of the connection between the assembly portion 210 - 1 and the water-stirring portion 240 .

[0126] In this embodiment, the water stirring part 240 is connected to the stirring shaft 300 that can rotatably pass through the bottom of the washing tub 100 through the assembly part 210-1, so that the water stirring member 200 can rotate relative to the washing tub 100. Specifically, the assembly part 210-1 and the stirring shaft 300 are circumferentially positioned by splines, rotate together, and are axially positioned by screws 210-7.

The spline groove 210-6 is formed on the assembly portion 210-1 of the water stirring member 200.

[0128] In this embodiment, the top of the water stirring member 200 is provided with an opening communicating with the cavity 210-9 inside the hollow column, and the screw 210-7 enters the cavity 210-9 through the opening and downwardly connects with the stirring shaft 300 key-connected in the assembly portion 210-1, thereby axially fixing the water stirring member 200 with the stirring shaft 300. In order to prevent water from entering the cavity 210-9, a blocking component is installed at the opening.

[0129] Preferably, a sealing groove 210-4 is provided on the top of the water stirring member 200, and the sealing groove 210-4 is formed by being coaxially recessed downward from the top surface of the water stirring plate 230. An opening communicating with the mold cavity 210-9 is provided on the bottom of the sealing groove 210-4.

[0130] Specifically, the upper end of the assembly part 210-1 is provided with a through hole, preferably a threaded hole, the rod of the screw 210-7 passes through the top of the assembly part 210-1 and is tightened in the threaded hole, and the head of the screw 210-7 abuts against the top of the assembly part 210-1. The operator disassembles and assembles the screw 210-7 through the opening on the bottom of the sealing groove 210-4 and the cavity 210-9 of the hollow column 210-8. The screw is preferably a countersunk screw.

[0131] The sealing groove 210 - 4 is provided with a sealing cover 210 - 5 for sealing the upper end of the water stirring member 200 to prevent washing water from entering the interior of the water stirring member 200 .

[0132] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion. The flat plate portion covers the notch of the sealing groove 210-4 and is embedded in the top of the water stirring member 200. The inserting portion is inserted into the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0133] The top of the flat plate portion and the top of the water stirring member 200 are in the same plane.

[0134] The sealing groove 210-4 includes a first section and a second section with increasing diameters from top to bottom. The lower end of the plug-in portion is provided with a limiting protrusion protruding from the outer wall of the lower end of the plug-in portion in a direction away from the axis of the water-stirring member 200, and the limiting protrusion is engaged at the junction between the first section and the second end.

[0135] Preferably, the inner wall of the first section and the inner wall of the second section of the sealing groove 210-4 are transitionally connected by a conical surface that is inclined from top to bottom in a direction away from the axis of the water stirring member 200, the shape of the limiting protrusion is adapted to the shape between the first section and the second section of the sealing groove 210-4, the outer peripheral surface of the limiting protrusion is in contact with the inner wall of the second section, and the top of the limiting protrusion is in contact with the conical surface between the first section and the second section of the limiting groove.

[0136] In this embodiment, a sealing ridge extending along the circumference of the plug-in portion is provided in the middle of the plug-in portion, and the plug-in portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 through the sealing ridge. Preferably, the sealing ridge extends along the circumference of the plug-in portion and is provided with multiple circles arranged at intervals along the axial direction of the plug-in portion.

[0137] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring member 200 to improve the smoothness of the insertion of the sealing cover 210 - 5 .

[0138] The side wall of the support column 210 is also provided with a raised water-stirring rib 220, but unlike the above-mentioned first embodiment, the radial dimension of the water-stirring rib 220 along the washing tub 100 can remain constant as the height increases, or can also change gradually or stepwise. The distance between the side wall of the support column 210 and the barrel wall of the washing tub 100 decreases as the height increases, so that the distance between the side of the water-stirring member 200 and the barrel wall of the washing tub 100 shows a trend of decreasing as the height increases. Similar to the above-mentioned first embodiment, in this embodiment, the clothes can also form a washing space between the side wall of the assembly portion 210-1, the inner surface of the barrel bottom 100-3 extending outward from the installation portion 100-2 to the inner circumferential wall of the washing tub 100, the water-stirring rib 220 and the inner circumferential wall of the washing tub;

[0139] In a specific solution 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 Dmax of the water stirring member 200. The side wall of the first extension section 211 extends upwardly and tilts from the bottom 100-3 of the washing tub 100, gradually approaching the tub wall of the washing tub 100. 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 where the maximum radius Dmax of the water stirring member 200 is located, so that the clothes can be washed below the side wall of the second extension section 212 and move toward the periphery along the side wall of the second extension section 212.

[0140] More specifically, the side wall of the first extension section 211 extends in a straight line and is inclined outward at a small angle relative to the vertical direction. The side wall of the second extension section 212 has a larger angle with the vertical direction than the side wall of the first extension section 211, 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.

[0141] In this embodiment, the upper end of the support column 210 is also provided with a water stirring tray 230, and 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 structure, which effectively reduces the problem of a cleaning dead corner between the upper end of the support column 210 and the lower surface of the water stirring tray 230 that cannot be touched by clothes.

[0142] In a detailed solution, the upper end of the side wall of the second extension section 212 overlaps 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 .

[0143] In the preferred embodiment of this embodiment, Fig.21As shown, the upper side surface of the water stirring tray 230 is a curved surface with a middle area higher than the outer peripheral area, and a protruding 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 washing water above the water stirring tray 230, and can also rub the clothes above the water stirring tray 230, thereby enhancing the washing effect.

[0144] Further, in this embodiment, the side wall of the second extension section 212 forms a first guide surface 213, which is used to guide the clothes below the first guide surface 213 to move toward the periphery during washing. The side wall of the first extension section 211 forms a second guide surface 214, which is used to guide the clothes to rise to the first guide surface 213 along the second guide surface 214 during washing.

[0145] Specifically, when washing, the water stirring member 200 rotates relative to the washing tub 100, so that the clothes move along the bottom 100-3 of the washing tub 100 toward the central area, then move upward along the first guide surface 213 to the second guide surface 214, move toward the periphery under the guidance of the second guide surface 214, and then fall in the area close to the wall of the washing tub 100, forming a circular path. On the one hand, the tumbling of the clothes in the tub can be enhanced to improve the washing effect, and on the other hand, the probability of the clothes concentrating toward the center and getting tangled is reduced.

[0146] 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 both and the vertical direction is the same. That is, 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.

[0147] As another specific embodiment, 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, so that an angle less than but close to 180° is formed at the connection between the first guide surface 213 and the second guide surface 214. In this way, when the clothes move upward along the second guide surface 214 to the first guide surface 213, it can play a certain buffering role on the clothes, and strengthen the tendency of the clothes to move toward the periphery in a rolling manner.

[0148] In a further solution of this embodiment, the water stirring rib 220 has 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 circumference 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 the two adjacent water stirring ribs 220, and the clothes can contact the side wall of the first extension section 211, so as to move upward along the side wall of the first extension section 211, that is, the second guide surface 214.

[0149] In this way, the area between two adjacent water-stirring ribs 220 of the side walls of the first extension section 211 and the second extension section 212 can contact the clothes without generating dead corners where dirt is easily accumulated.

[0150] In this embodiment, the radial dimension of the water stirring rib 220 along the washing tub 100 increases first and then decreases from the lower end to the upper end.

[0151] As a specific embodiment, the cross-sectional shape of the water stirring rib 220 parallel to the radial direction of the washing tub 100 is close to a shuttle shape, and the peripheral 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 peripheral edge of the water stirring member 200 forms a curve that bends toward the barrel wall of the washing tub 100. The upper end of the peripheral edge of the water stirring rib 220 coincides with the outer periphery of the water stirring plate 230.

[0152] The water-stirring ribs 220 have the above-mentioned structure, which can form a Coanda effect during washing, driving the water flow to flow along the outer peripheral edge of the water-stirring ribs 220, so that in the area close to the axis of the washing tub 100, the water flow has a flow tendency to fit the outer peripheral edge of the water-stirring ribs 220, and as the height increases, the flow direction of the water flow is closer to upward rather than flowing toward the periphery. In this way, the lifting force of the water flow on the clothes in the area close to the axis can be enhanced, driving the clothes to move upward to the first guide surface 213, and finally forming a circular path.

[0153] It can be understood that the clothes moving along the bottom 100-3 of the barrel toward the central area can also be lifted along the outer edge of the water-stirring ribs 220 after contacting the water-stirring ribs 220. After moving to the maximum radius Dmax of the water-stirring member 200, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom 100-3 of the barrel along the wall of the washing barrel 100.

[0154] In the preferred solution of this embodiment, the water stirring member 200 is installed in the washing barrel 100, and there is a certain interval between the lower end of the water stirring rib 220 and the barrel bottom 100-3 of the washing barrel 100 to avoid a cleaning dead angle between the water stirring rib 220 and the barrel bottom 100-3. Specifically, the bottom of the support column 210 has a connecting portion rotatably inserted into the installation through hole 10-21 on the barrel bottom 100-3, and the lower end of the water stirring rib 220 is at least flush with the upper end of the connecting portion, preferably higher than the upper end of the connecting portion. The stirring shaft 300 used to drive the water stirring member 200 to rotate is inserted into the connecting portion from the lower end for fixing.

[0155] More preferably, a smoothly transitioned rounded corner 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 of the inside of the washing barrel 100 to the greatest extent.

[0156] 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 corners that may scratch and damage clothes.

[0157] like Fig.19 and Fig. 20 As shown, in this embodiment, the water stirring member 200 includes a mounting portion 210-1 and a water stirring portion 240 extending upward from the mounting portion 210-1. The stirring shaft 300 rotatably passes through the mounting portion 100-2 of the barrel bottom 100-3 and is connected to the mounting portion 210-1.

[0158] As a specific embodiment, the distance from the side wall of the mounting portion 210- to the inner surface of the peripheral wall of the washing tub 100 is close to the distance from the side wall of the stirring shaft 300 to the inner surface of the peripheral wall of the washing tub 100. More specifically, the distance from the side wall of the mounting portion 210- to the inner surface of the peripheral wall of the washing tub 100 is slightly smaller than the distance from the side wall of the stirring shaft 300 to the inner surface of the peripheral wall of the washing tub 100.

[0159] In this way, the washing surface 100 - 3 of the barrel bottom 100 - 3 extending outward from the mounting portion 100 - 2 is completely exposed to the washing space above, thereby avoiding the problem of dirt and grime accumulating in the barrel bottom 100 - 2 .

[0160] In this embodiment, the dehydration shaft 110 connected to the washing barrel 100 is mounted on the stirring shaft 300. At the upper end of the dehydration shaft 110, a sealing structure 120 is arranged between the dehydration shaft 110 and the stirring shaft 300, so that the dehydration shaft 110 and the stirring shaft 300 can be sealed and connected relatively rotatably to prevent water from entering between the dehydration shaft 110 and the stirring shaft 300.

[0161] Specifically, the sealing structure 120 is sleeved on the stirring shaft 300 , and the outer peripheral wall of the sealing structure 120 is relatively fitted with the inner peripheral wall of the dehydration shaft 110 .

[0162] As a specific implementation, the upper end surface of the sealing structure 120 is flush or substantially flush with the inner surface of the barrel bottom 100 - 3 , thereby preventing a gap that is easy to harbor dirt and grime from being formed between the dehydration shaft 110 and the stirring shaft 300 .

[0163] The above-mentioned “substantially flush” means that the upper end surface of the sealing structure 120 may be slightly higher than the inner surface of the barrel bottom 100 - 3 , or slightly lower than the inner surface of the barrel bottom 100 - 3 .

[0164] For the structure where the upper end surface of the sealing structure 120 is slightly higher than the inner surface of the barrel bottom 100-3, no concave gap is formed between the dehydration shaft 110 and the stirring shaft 300. For the structure where the upper end surface of the sealing structure 120 is slightly lower than the inner surface of the barrel bottom 100-3, although a concave gap is formed, the concave size of the gap is very small, and the flushing force of the water flow passing through this place during washing is sufficient to remove the lint and dirt there, and no dirt will remain.

[0165] As a specific embodiment, the lower end surface of the water stirring member 200, that is, the lower end surface of the assembly portion 210-1, is at least partially arranged opposite to the upper end surface of the sealing structure 120. The assembly portion 210-1 is mounted on the upper end of the stirring shaft 300, and the lower end radius of the assembly portion 210-1 is greater than the radius of the stirring shaft 300.

[0166] Furthermore, a radius of a lower end of the fitting portion 210 - 1 is greater than an outer diameter of the sealing structure 120 .

[0167] In a specific embodiment, the difference between the radius of the lower end of the assembly portion 210 - 1 and the outer diameter of the sealing structure 120 is close to the wall thickness of the assembly portion 210 - 1 in the radial direction.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
