Description

Technical Field

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

[0002] As a convenient clothes washing device, washing machines have been widely used in people's lives. Existing washing machines are divided into drum washing machines and pulsator washing machines, among which pulsator washing machines are popular with users due to their good washing 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, and cannot be effectively cleaned by simply flushing. In addition, dirt and lint are easy to breed bacteria 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 more 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] On the other hand, for washing machines with a bottom impeller, the clothes cover a large area on the impeller surface during washing. The friction between the impeller and the clothes drives the clothes to move in the washing water, which increases the entanglement and wear of the clothes. At the same time, the friction between the clothes and the impeller will also increase the energy consumption required by the drive motor to drive the impeller to rotate.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing tub assembly and washing equipment for a washing device, which can avoid dirt and grime accumulation between the water stirring component and the bottom surface of the washing tub on the one hand, and reduce the energy consumption of the motor used to drive the water stirring component on the other hand.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A washing tub assembly of a washing device comprises a washing tub and a water stirring member rotatably arranged inside the washing tub, wherein the water stirring member has a maximum diameter along the radial direction of the washing tub at a certain distance from the bottom surface of the washing tub, and a first guide surface extending from an area close to an axis toward the periphery is formed at the area, for guiding the clothes below the area to move toward the periphery along the first guide surface during washing.

[0010] Furthermore, the water-stirring member forms a second guiding surface extending upward below the largest diameter portion, for guiding the clothes to move along the second guiding surface toward the largest diameter portion of the water-stirring member during washing.

[0011] Further, the water stirring member includes a support column coaxially arranged with the washing tub, and a water stirring plate arranged perpendicularly to the axis of the support column;

[0012] The outer periphery of the water stirring tray forms the largest diameter portion of the water stirring member. The first guide surface is formed at the lower side of the water stirring tray and extends horizontally or obliquely upward from an area close to the center of the water stirring tray to the outer periphery.

[0013] Furthermore, a second guide surface extending upward is formed on the side of the support column. During washing, part or all of the clothes move along the bottom of the washing tub toward the central area, and then move upward along the second guide surface to the first guide surface.

[0014] Furthermore, the diameter of the connection between the support column and the lower surface of the water stirring plate is smaller than the diameter of the water stirring plate; the first guide surface includes at least a partial area of ​​the lower surface of the water stirring plate, and the second guide surface includes at least an area where the side wall of the support column is located below the water stirring plate.

[0015] Furthermore, a transition curved surface for smooth transition is provided at the connection between the side wall of the support column and the lower surface of the water stirring plate, and the first guide surface also includes the transition curved surface.

[0016] Furthermore, the side wall of the support column extends upward from the bottom surface of the washing tub to a position lower than the lower surface of the water-stirring tray, forming a second guide surface. During washing, the clothes move along the bottom of the washing tub toward the central area, and then move upward along the second guide surface to the first guide surface; the first guide surface extends upward from the upper end of the second guide surface to the outer periphery to the lower surface of the water-stirring tray.

[0017] Furthermore, an extended end of the first guide surface coincides with an outer circumference of the water stirring tray.

[0018] Furthermore, the water stirring member also includes a water stirring rib protruding from the side wall of the support column; the water stirring rib is arranged below the first guide surface and has a certain extension length along the axial direction of the washing barrel, and the upper end of the water stirring rib is connected to the first guide surface.

[0019] A washing device comprises the washing tub assembly of the washing device as described above.

[0020] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0021] In the present invention, the largest diameter of the water stirring member is set at a certain distance from the bottom surface of the washing barrel, and a first guide surface is formed there. On the one hand, the clothes can be washed below the largest diameter of the water stirring member, and come into contact and friction with the guide surface and the surrounding outer surface of the water stirring member, preventing the attachment of wire scraps or other dirt to the outer surface of the water stirring member, thereby avoiding the problem of dirt and dirt easily accumulating between the water stirring member and the bottom surface of the washing barrel. On the other hand, the clothes can move outward along the first guide surface, which enhances the effect of the water stirring member rotating to drive the clothes to move outward and flip during the washing process, thereby improving the washing effect and preventing the clothes from gathering in the center and getting entangled. In addition, since the clothes can be washed below the largest diameter of the water stirring member without covering the water stirring member over a large area, the energy consumption of the motor used to drive the water stirring member can be reduced.

[0022] In the present invention, the water stirring member includes a water stirring plate, and a first guide surface is formed on the lower side of the water stirring plate, and the first guide surface is directly opposite to the bottom surface of the washing tub and is arranged at a certain distance, so that the clothes can be washed in the space between the water stirring plate and the bottom surface of the washing tub, and contact with the area of ​​the side wall of the support column located below the water stirring plate, further avoiding the possibility of the existence of lint and dirt adhering to the outer surface of the water stirring member. By setting a transition curved surface or setting the first guide surface to extend upwardly in an inclined direction toward the outer circumference, it is further prevented that there is a dead corner on the water stirring member that cannot contact the clothes to be washed and is easy to hide dirt.

[0023] In the present invention, the water stirring ribs protruding from the side wall of the support column are used to strengthen the stirring force of the clothes and water flow in the barrel when the water stirring member rotates, thereby enhancing the washing effect. By arranging the water stirring ribs to be connected to the first guide surface, and the size of the water stirring ribs changing in the extension direction thereof, a dead angle between the outer surface of the water stirring ribs and the first guide surface and the bottom surface of the washing barrel is avoided, and the cleanliness of the water stirring member is guaranteed to the greatest extent.

[0048] 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

[0049] 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.

[0050] 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.

[0051] 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.

[0052] like Figures 2 to 20 As shown, an embodiment of the present invention provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing device having a clothes washing function.

[0053] Specifically, the washing tub assembly includes a washing tub 100 and a water stirring member 200 rotatably disposed inside the washing tub 100. The washing device further includes a driving device, which is transmission-connected to the washing tub 100 and the water stirring member 200, respectively.

[0054] More specifically, the output shaft of the driving device is respectively connected to the stirring shaft 300 and the dehydrating shaft 110. 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 110 is fixed to the bottom of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0055] 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.

[0056] However, when the clothes C are washed, the lint and dirt are mixed into the washing water. If there is a narrow gap between the water stirring member 200 and the washing tub 100, the lint and dirt are easily hidden in the gap and are difficult to be taken out by the impact of the water flow during the washing process. Over time, the gap between the water stirring member 200 and the washing tub 100 will cause dirt to accumulate and bacteria to breed, causing secondary contamination of the clothes C.

[0057] On the other hand, during washing, the clothes C tend to gather toward the central axis under the influence of the water flow stirred by the water stirring member 200, and it is easy for the clothes C to get tangled. Once the clothes C are tangled together, some of the clothes C cannot fully contact the washing water, which affects the washing effect of the clothes C. In addition, in the subsequent dehydration process, it will make it difficult to evenly distribute the clothes C, thereby causing an eccentric dehydration failure.

[0058] Embodiment 1

[0059] like Figure 2 and Figure 3 As shown, this embodiment provides a washing tub assembly for a washing device, and a washing device having the washing tub assembly, which are used to solve the problem that there are dead corners between the water stirring member 200 and the washing tub 100 where dirt and grime are hidden, which are difficult to clean and easily cause clothes C to be entangled during washing.

[0060] Specifically, the washing tub assembly described in this embodiment includes a washing tub 100, and a water stirring member 200 rotatably disposed inside the washing tub 100. The water stirring member 200 extends upward from the bottom of the washing tub 100, and has a maximum diameter at a certain distance from the bottom surface of the washing tub 100 (i.e., the inner surface of the bottom of the washing tub 100), and the certain distance enables the clothes C to be washed below the position where the maximum diameter Dmax of the water stirring member 200 is located.

[0061] The water stirring member 200 and the washing tub 100 described in this embodiment have the above-mentioned matching structure. Compared with the traditional pulsator washing machine or the agitator washing machine with a radial agitator, there is a washing space below the maximum diameter Dmax of the water stirring member 200. The washing space is composed of the surface of the water stirring member 200 below the maximum diameter Dmax, the barrel wall of the washing tub 100, and the barrel bottom of the washing tub 100. The clothes C can be washed in the washing space, so that the surface of the water stirring member 200 below the maximum diameter Dmax and the barrel bottom of the washing tub 100 can contact the washed clothes C in the barrel. During the washing process, the friction between the clothes C and the surface of the water stirring member 200 can prevent the attachment of line scraps or other dirt on the surface of the water stirring member 200, effectively avoiding the problem that dirt is easy to hide between the water stirring member 200 and the barrel bottom and is difficult to clean, thereby improving the user experience.

[0062] At the same time, since the clothes C can be washed in the space between the maximum diameter Dmax of the water-stirring member 200 and the bottom of the washing tub 100, and the clothes C will not cover the water-stirring member 200 over a large area like a pulsator washing machine, the resistance of the clothes C to the rotation of the water-stirring member 200 can be reduced, thereby reducing the energy consumption of the motor of the driving device to drive the water-stirring member 200 to rotate.

[0063] It should be noted that, in the embodiment of the present invention, the diameter of the water stirring member 200 refers to the diameter of the water stirring member 200 taken along a direction perpendicular to the rotation axis thereof (see Figure 4 ), the point on the obtained cross section that is farthest from the center of rotation is twice the distance between the center of rotation.

[0064] 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 the non-circular shape shown, the diameter is twice 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).

[0065] As a specific implementation, in this embodiment, the distance h between the maximum diameter Dmax of the water stirring member 200 and the inner surface of the barrel bottom is more than 10 cm, thereby ensuring that the clothes C can be washed below the maximum diameter Dmax.

[0066] In a further solution of this embodiment, the water stirring member 200 forms a first guide surface extending toward the periphery at its maximum diameter Dmax. During washing, the first guide surface can guide the clothes C located below the maximum diameter Dmax to move toward the periphery along the first guide surface.

[0067] Specifically, 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 that the water stirring member 200 and the washing tub 100 generate relative rotation. Through the setting of the first guide surface, the clothes C can move from the central area to the periphery below the maximum diameter Dmax of the water stirring member 200, and after moving to the periphery for a certain distance, or moving beyond the coverage of the first guide surface, the clothes C will fall under the action of gravity and the water flow. In this way, the effect of the water stirring member 200 rotating to drive the clothes C to move to the periphery and flip during the washing process is enhanced, thereby improving the washing effect, while preventing the clothes C from gathering toward the center and getting entangled.

[0068] Furthermore, the water stirring member 200 of the present embodiment does not have a disc-shaped stirring portion at the bottom, that is, the water stirring member 200 does not have a structure extending radially along the washing barrel 100 to cover the barrel bottom 100-3 at the bottom area of ​​the washing barrel 100, thereby ensuring that the inner surface of the barrel bottom is exposed to the washing space that can contact the clothes during washing.

[0069] In this embodiment, the side of the water stirring member 200 is configured such that as the height of the rotation axis increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 remains constant, or changes gradually or stepwise.

[0070] As a specific implementation method, Figure 2 ,as well as Figure 12 to Figure 14 As shown, the water stirring member 200 has a single maximum diameter Dmax in the height direction. Further, at least below the maximum diameter Dmax, as the height increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 decreases with the increase in height, and finally, at the maximum diameter Dmax, a first guide surface extending toward the periphery can be formed.

[0071] It should be noted that the single maximum diameter point Dmax may refer to the water-stirring member 200 having the maximum diameter point Dmax at a specific height position, or may refer to the water-stirring member 200 having the maximum diameter point Dmax within a certain continuous height range.

[0072] In the first specific embodiment, if Fig.12 As shown, the maximum diameter 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 diameter. The water stirring member 200 forms a first guide surface at the lower side of its top, and during washing, the clothes moving close to the top of the water stirring member 200 will move toward the periphery along the first guide surface.

[0073] In the second specific scheme, if Figure 2 As shown, the maximum diameter 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 surface of the water stirring member 200 at the maximum diameter Dmax is a curved surface convex upward, and the highest point of the curved surface forms the top of the water stirring member 200. In this solution, the formation position of the first guide surface is similar to that in the previous solution, and is also on the lower side of the top of the water stirring member 200.

[0074] In the third specific scheme, if Fig.13 and Fig.14 As shown, the maximum diameter Dmax of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0075] 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 diameter of the water stirring member 200 gradually increases from the bottom of the washing tub 100 to the top until the maximum diameter Dmax is formed, and then the diameter of the water stirring member 200 gradually decreases and finally reaches the top of the water stirring member 200.

[0076] In the above solution, the first guide surface is formed in the middle of the water stirring member 200 in the height direction, and the laundry washed below the maximum diameter Dmax of the water stirring member 200 can move toward the periphery along the first guide surface.

[0077] In another detailed scheme, Fig.14 As shown, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 has a sudden change at at least one height position. Specifically, as the height increases, the diameter of the water stirring member 200 gradually increases from the bottom of the washing tub 100 to the top, and when reaching a certain height, the diameter suddenly increases to form the maximum diameter Dmax, and then the diameter of the water stirring member 200 remains constant within a certain height range, then suddenly decreases, and then continues to gradually shrink, and finally forms the top of the water stirring member 200.

[0078] In this solution, the distance from the maximum diameter Dmax of the water stirring member 200 to the bottom of the washing tub 100 refers to the distance from the lowest height in the height range where the diameter of the water stirring member 200 remains constant to the bottom of the washing tub 100. The first guide surface at least includes a surface formed at the location where the diameter of the water stirring member 200 changes suddenly and facing the bottom of the washing tub 100.

[0079] As another specific implementation method, Fig.15As shown, the water stirring member 200 has a plurality of interval-distributed maximum diameter points Dmax in the axial direction of the washing tub 100. Specifically, as the height increases, the diameter of the water stirring member 200 increases and decreases alternately, each time increasing to the same diameter size and then decreasing, thereby forming a plurality of interval-distributed maximum diameter points Dmax. In this solution, each maximum diameter point Dmax of the water stirring member 200 can form a first guide surface extending toward the periphery, thereby driving the clothes to move toward the periphery at different heights.

[0080] The different structures provided above can all achieve the goal of washing clothes below the maximum diameter Dmax of the water stirring member 200, preventing the existence of cleaning dead corners between the water stirring member 200 and the bottom of the washing tub 100 where dirt is easily accumulated, and forming a first guide surface at the maximum diameter Dmax to guide the clothes to move toward the periphery, thereby reducing the entanglement of clothes.

[0081] In a further solution of this embodiment, the water stirring member 200 further forms a second guiding surface extending upward below the maximum diameter Dmax, which is used to guide the clothes C to move along the second guiding surface toward the maximum diameter Dmax of the water stirring member 200 during washing. Through the cooperation of the first guiding surface and the second guiding surface, the clothes C can move along a circular path below the maximum diameter Dmax of the water stirring member 200 for washing.

[0082] The annular path mentioned above means that the water moves toward the center in the bottom area of ​​the washing tub 100, is lifted by the water stirring member 200 to a position close to the maximum diameter Dmax of the water stirring member 200, moves toward the periphery, and then falls.

[0083] See also Fig.16 and Fig.17 As a specific solution, the circular path of the clothes moving below the maximum diameter Dmax of the water stirring member 200 during washing includes: the clothes move along the bottom of the washing tub 100 toward the central area, move upward along the side of the water stirring member 200 in the central area to below the maximum diameter Dmax and then move toward the periphery, and move downward in the area close to the wall of the washing tub 100.

[0084] In a specific solution of this embodiment, the water stirring member 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water stirring plate 230 arranged perpendicular to the axis of the support column 210. The support column 210 is used to drive the driving device connected to the washing device, so that the water stirring member 200 can rotate under the drive of the driving device. The outer periphery of the water stirring plate 230 forms the maximum diameter Dmax of the water stirring member 200, and the first guide surface is formed on the lower side of the water stirring plate 230, extending horizontally or obliquely upward from the area close to the center of the water stirring plate 230 to the outer periphery.

[0085] The second guide surface is formed on the side of the support column 210. During washing, the clothes C move along the bottom of the washing tub 100 toward the central area, then move upward along the second guide surface to the first guide surface, move toward the periphery along the first guide surface, and then fall back to the bottom of the tub along the wall of the washing tub.

[0086] In the above scheme, during the washing process, the water stirring member 200 and the washing tub 100 generate relative rotation. Since the diameter of the water stirring member 200 near the bottom of the tub is smaller, during washing, the clothes C at the bottom of the washing tub 100 can be gathered along the bottom of the tub toward the center, then move upward along the second guide surface to below the first guide surface, then move toward the periphery along the first guide surface, and then fall along the wall of the washing tub to the bottom area of ​​the tub, thus forming a circular motion path that turns from the center to the outside.

[0087] In a further solution of this embodiment, the maximum diameter Dmax of the water-stirring member 200 is also at a certain distance from the barrel mouth of the washing barrel 100 in the height direction, so that the washing water level can be higher than the maximum diameter Dmax of the water-stirring member 200, so that the clothes C can be washed above the position where the maximum diameter Dmax of the water-stirring member 200 is located.

[0088] In the above scheme, the washing tub 100 can accommodate clothes C for washing both above and below the maximum diameter Dmax of the water stirring member 200. In this way, on the other hand, the outer surface of the water stirring member 200 can basically contact the washed clothes C and generate friction with the clothes C. By increasing the surface area contacting the clothes C, the washing effect can be enhanced.

[0089] In a further embodiment, the height at which the maximum diameter Dmax of the water stirring member 200 is located is set between the highest water level and the lowest water level of the washing device. In this way, when the washing device uses different water levels for washing, the water stirring member 200 rotates relative to the washing tub 100 to generate different water flow modes to drive the clothes C to move for washing.

[0090] Specifically, the washing tub 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 diameter Dmax of the water stirring member 200, the laundry moves along a reverse circular path in the water.

[0091] 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 space below the maximum diameter Dmax of the water stirring member 200, move toward the central area along the bottom of the washing tub 100 and gather, and then are lifted to below the first guide surface along the second guide surface formed by the side wall of the support column 210, and then move toward the periphery along the first guide surface, and then fall to the bottom of the tub in the area close to the wall of the washing tub 100, forming a circular motion.

[0092] like Fig.17 As shown, when a high water level W2 higher than the maximum diameter Dmax of the water stirring member 200 is used, in the area below the maximum diameter Dmax of the water stirring member 200, the clothes move along the above-mentioned circular path in the water; and in the area above the maximum diameter Dmax of the water stirring member 200, the clothes move close to the circumferential direction of the washing tub 100.

[0093] 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 diameter 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 maximum diameter Dmax of the water stirring member 200, the clothes move alternately forward and reverse along the circumference of the washing tub 100 as the water stirring member 200 rotates alternately forward and reverse.

[0094] 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 more diverse washing method options. In addition, in the area below the maximum diameter Dmax of the water stirring member 200, since the clothes move along the reverse circular path, on the one hand, the clothes can be tumbled and 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 at the center, causing the clothes to be entangled, is avoided.

[0095] In this embodiment, the diameter of the connection between the support column 210 and the lower surface of the water stirring tray 230 is smaller than the diameter of the water stirring tray 230, that is, most of the lower surface of the water stirring tray 230 is exposed to the internal space of the washing tub 100. The first guide surface at least includes a portion of the lower surface of the water stirring tray 230, and the second guide surface at least includes the area of ​​the side wall of the support column 210 below the water stirring tray 230.

[0096] As a specific implementation method, Figure 2 As shown, the water stirring plate 230 is connected to the upper end of the support column 210. Specifically, the upper end of the support column 210 is connected to the center of the lower surface of the water stirring plate 230, and the area of ​​the lower surface of the water stirring plate 230 not covered by the upper end surface of the support column 210 forms the first guide surface.

[0097] More specifically, the side wall of the support column 210 extends upward from the bottom of the washing tub 100 in a vertical direction or a nearly vertical direction until it is connected to the lower surface of the water stirring member 200. The side wall of the support column 210 starting from the area higher than the bottom surface of the washing tub 100 can serve as the second guide surface.

[0098] In a further embodiment, a transitional curved surface for smooth transition is provided at the connection between the side wall of the support column 210 and the lower surface of the water stirring plate 230, and the first guide surface also includes the transitional curved surface. In this way, a cleaning dead angle between the upper end of the support column 210 and the water stirring plate 230 where it is difficult to contact the clothes C is avoided.

[0099] In a further solution of this embodiment, the water stirring component 200 also includes a water stirring rib 220 protruding from the side wall of the support column 210, and on the lower side of the water stirring plate 230, the water stirring rib 220 has a certain extension length along the axial direction of the washing barrel 100, and the upper end of the water stirring rib 220 is connected to the first guide surface.

[0100] The protruding direction of the water stirring rib 220 coincides with the radial direction of the washing tub 100, or is at a certain angle to 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 effectively stir the clothes C and the water flow in the tub. The upper end of the water stirring rib 220 is connected to the first guide surface, that is, the lower surface of the water stirring plate 230, which can 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.

[0101] Preferably, rounded transitions are provided between the two side surfaces of the water stirring ribs 220 and the lower side 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.

[0102] In this embodiment, 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. In this way, the cleaning dead corners on the side wall of the support column 210 where dirt is easily attached are avoided, and the effect of guiding the clothes C to move upward by the second guide surface formed by the side wall of the support column 210 is also ensured.

[0103] It should be noted that in the above scheme, the side of the water-stirring member 200 includes both the side wall of the support column 210 and the surface on the water-stirring rib 220 that is farthest from the rotation axis, and the diameter of the water-stirring member 200 is twice the distance between the farthest point on the water-stirring rib 220 from the rotation axis and the rotation axis.

[0104] In the above structure, the diameter of the water stirring member 200 specifically refers to the diameter of the water stirring member 200 taken along the horizontal direction. On the obtained cross section, the water stirring rib 220 is twice the distance from the farthest end of the axis to the central axis. When the number of the water stirring ribs 220 is an even number, the length of the line connecting the farthest ends of the two relative water stirring ribs 220 from the axis is the diameter of the water stirring member 200 at that location. When the number of the water stirring ribs 220 is an odd number, there are no relatively arranged water stirring ribs 220. At this time, the cross section of the water stirring portion 240 taken along the horizontal direction does not constitute an axisymmetric figure, but the diameter of the horizontal cross section of the water stirring portion 240 is still twice the distance from the farthest end of the axis to the central axis of the water stirring rib 220.

[0105] In another specific embodiment, the water stirring ribs extend spirally along the side wall around the support column. In this case, the cross section of the water stirring member in the horizontal direction may not form a regular geometric shape, and the radius is still twice the distance from the farthest end of the water stirring rib from the axis to the central axis on the cross section.

[0106] Furthermore, in this embodiment, the radial dimension of the water stirring ribs 220 along the washing tub 100 increases with increasing height, thereby forming a structure in which the distance between the side of the water stirring member 200 and the wall of the washing tub 100 decreases with increasing height.

[0107] As a specific 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 axis of the support column 210, so that the radial dimension of the water stirring rib 220 along the washing tub 100 is maximized as much as possible, thereby enhancing the stirring force of the washing water and improving the washing effect.

[0108] As a preferred solution, the lower end of the water stirring rib 220 is spaced from the bottom of the washing tub 100. Specifically, the bottom of the support column 210 has a mounting portion for connecting the stirring shaft 300, and the outer peripheral edge of the water stirring rib 220 extends upward from a certain distance from the upper end of the mounting portion on the side wall of the support column 210, and the inclination angle remains constant or gradually changes, and finally extends to the outer periphery of the water stirring plate 230. There is no other structure extending radially along the washing tub 100 between the lower end of the water stirring rib 220 and the mounting portion, and the bottom of the washing tub 100 will not be covered, ensuring that there is basically no area on the bottom of the washing tub 100 that cannot contact the clothes.

[0109] In the first specific embodiment, a groove structure with an open upper side is provided on the bottom of the washing tub 100, and the stirring shaft 300 extends into the inner side of the washing tub 100 from the mounting through hole provided on the bottom wall of the groove structure, and the assembly part and the groove structure are rotatably plugged and matched, and the lower end of the water stirring rib 220 is not lower than the upper end of the assembly part, so that the lower end surface of the water stirring rib 220 can contact the clothes. At the same time, since there is no other structure extending along the radial direction of the washing tub between the lower end of the water stirring rib 220 and the assembly part, the area of ​​the bottom of the washing tub 100 located at the periphery of the groove structure can also contact the clothes, preventing the attachment of lint and dirt.

[0110] In the second specific embodiment, there is a gap between the lower end surface of the assembly part and the bottom of the washing tub, and the stirring shaft 300 passes through the mounting through hole opened on the bottom of the washing tub 100 and is connected to the assembly part. The gap allows the lower end surface of the assembly part and the area of ​​the bottom of the washing tub 100 located at the periphery of the mounting through hole to contact the clothes, thereby preventing the existence of a cleaning dead corner where dirt is easily attached.

[0111] In the third specific embodiment, the stirring shaft 300 extends into the washing barrel 100 through the mounting through hole on the bottom of the washing barrel 100, and the assembly part is mounted on the upper end of the stirring shaft 300, and there is a small gap between the lowermost end of the assembly part and the bottom of the washing barrel 100. The difference between the outer diameter and the inner diameter of the bottom of the assembly part is small enough so that the outer surface of the assembly part can contact the clothes during the washing process, and the area of ​​the bottom of the washing barrel 100 located at the periphery of the mounting through hole can contact the clothes, preventing the existence of cleaning dead corners that are easy to adhere to dirt. Preferably, the outer side wall of the assembly part and the side wall of the stirring shaft 300 have a smooth transition, further avoiding the possibility of cleaning dead corners.

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

[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 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 along the second guide surface under the rotation of the water stirring member 200 until they move to the lower side of the maximum diameter Dmax of the water stirring member 200. Under the lower side of the maximum diameter 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 first guide surface formed by the maximum diameter Dmax of the water stirring member 200, and finally fall back to the bottom of the tub in an 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 diameter point Dmax at a certain distance from the bottom of the tub, and forms a first guide surface extending toward the periphery thereat, and a second guide surface connected to the first guide surface is formed below the maximum diameter point Dmax. During washing, most of the bottom surface of the washing tub 100 is exposed to the washing water, and the clothes C can be washed below the maximum diameter point Dmax of the water stirring member 200, and fully contact and rub with the bottom of the washing tub 100 and the outer surface of the water stirring member 200, avoiding the problem of a cleaning dead corner between the water stirring member 200 and the washing tub 100 that is difficult to contact the clothes C, and easy accumulation of line scraps and dirt.

[0115] At the same time, the clothes C move along the bottom of the washing tub 100, the second guide surface, the first guide surface and the wall of the washing tub 100 to form a circular path for washing, that is, they gather toward the center at the bottom of the tub, and then are lifted to a certain height, and then move toward the periphery under the maximum diameter Dmax of the water stirring member 200 and fall. In this way, the washing effect of the clothes C is enhanced, and the clothes C can be effectively prevented from being entangled.

[0116] Embodiment 2

[0117] like Figures 18 to 20 As shown, this embodiment provides a washing bucket assembly of a washing device, and a washing device having the washing bucket assembly. The difference between the washing bucket assembly provided in this embodiment and the above-mentioned embodiment 1 is that the first guide surface 213 extends upwardly from the upper end of the second guide surface 214 to the lower side surface of the water stirring tray 230.

[0118] Specifically, in this embodiment, the side wall of the support column 210 extends upward from the bottom surface of the washing tub 100 to a position lower than the lower surface of the water stirring tray 230, forming the second guide surface 214. The first guide surface 213 extends upward from the end of the second guide surface 214 toward the periphery and is finally connected to the lower surface of the water stirring tray 230.

[0119] In the above solution, the support column 210 includes a first extension section 211 and a second extension section 212 connected to each other, wherein the first extension section 211 extends upward from the bottom of the washing tub 100, and its side wall forms the second guide surface 214. The second extension section 212 extends upward from the first extension section 211, and the diameter of the second extension section 212 gradually increases with the increase of the height, and its side wall forms the first guide surface 213. Through the above structure, the angle between the side wall of the upper end of the support column 210 and the lower surface of the water stirring tray 230 is greatly increased, thereby effectively reducing the problem of a cleaning dead angle between the upper end of the support column 210 and the lower surface of the water stirring tray 230 that cannot be touched by clothes.

[0120] It should be noted that the side wall of the first extension section 211 extends upward from the bottom of the washing tub 100, and can be extended vertically upward, or extended upward at an angle relative to the vertical direction, gradually approaching or moving away from the wall of the washing tub 100, or can be extended upward along a curve with a larger curvature and gradually approaching or moving away from the wall of the washing tub 100.

[0121] As a specific embodiment, the second guide surface 214 extends upward in a straight line and is inclined outward at a small angle relative to the vertical direction, so that as the height of the support column 210 increases, the distance between the second guide surface 214 and the wall of the washing tub 100 gradually decreases. At the lower end of the first guide surface 213, the angle between it and the vertical direction is not less than the angle between the second guide surface 214 and the vertical direction, and as the height increases, the angle between the first guide surface 213 and the vertical direction gradually increases, forming a curved surface that bends toward the side where the water stirring tray 230 is located.

[0122] In a specific solution, at the position where the first guide surface 213 and the second guide surface 214 are connected, the two have the same inclination angle, thereby achieving a smooth transition connection.

[0123] In another specific solution, the first guide surface 213 has a slightly higher inclination angle at the position where the first guide surface 213 and the second guide surface 214 are connected, 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, a certain buffering effect can be exerted on the clothes, and the tendency of the clothes to move toward the periphery in a tumbling manner can be strengthened.

[0124] In a detailed scheme of this embodiment, the upper end of the side wall of the second extension section 212, that is, the extended end of the first guide surface 213 located at the periphery coincides with the periphery of the water stirring plate 230, so that the lower side surface of the water stirring plate 230 is completely covered by the upper end surface of the support column 210.

[0125] In the preferred embodiment of this embodiment, Fig.19 As 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.

[0126] In this embodiment, a plurality of water stirring ribs 220 are also provided on the side wall of the support column 210. Specifically, 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. The plurality of water stirring ribs 220 are distributed 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 at the same time, the clothes can contact the side wall of the first extension section 211, thereby moving upward along the side wall of the first extension section 211, that is, the second guide surface 214.

[0127] 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.

[0128] Furthermore, in the present 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.

[0129] 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 tray 230.

[0130] 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 along the second guide surface 214 to the first guide surface 213, and finally forming a circular motion path.

[0131] It can be understood that the clothes moving along the bottom of the barrel toward the central area can also be lifted along the outer edge of the water-stirring ribs 220 after contacting the water-stirring ribs 220. After moving to the maximum diameter 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 of the barrel along the wall of the washing barrel 100.

[0132] 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 bottom of the washing barrel 100 to avoid the existence of a cleaning dead angle between the water stirring rib 220 and the bottom of the barrel. Specifically, the bottom of the support column 210 is provided with an assembly part 210-1 for connecting the stirring shaft 300, and the bottom of the washing barrel 100 has a groove structure for installing the assembly part 210-1. The assembly part 210-1 and the groove structure are rotatably plugged and matched. The stirring shaft 300 used to drive the water stirring member 200 to rotate passes through the installation through hole on the bottom wall of the groove structure, and is inserted into the assembly part 210-1 from the lower end for fixing. The lower end of the water stirring rib 220 is at least flush with the upper end of the assembly part 210-1, and preferably higher than the upper end of the assembly part 210-1. A water seal structure can be set between the assembly part 210-1 and the groove structure to prevent dirt from being hidden inside the groove structure.

[0133] 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.

[0134] 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.

[0135] It is understandable that the purpose of preventing the existence of cleaning dead corners can also be achieved by setting a certain interval between the lower end surface of the assembly part and the bottom of the washing bucket, or setting the difference between the outer diameter and the inner diameter of the assembly part to be small enough, so that the outer surface of the assembly part (including the outer side wall and the lower end surface) and the area of ​​the bottom of the washing bucket located at the periphery of the installation through hole can contact the clothes. In the above scheme, the bottom of the washing bucket does not need to be provided with a groove structure, but can adopt a structure in which the upper side surface of the bottom is a plane, and preferably a structure in which the peripheral area of ​​the installation through hole is convex upward.

[0136] As a specific implementation, the thickness of the water-stirring rib 220 in the circumferential direction gradually decreases radially outward, and along the axial direction, the thickness of the middle area of ​​the water-stirring rib 220 is greater than the thickness at the upper and lower ends.

[0137] In this embodiment, the first guide surface 213 and the second guide surface 214 for guiding the clothes are formed by the change of the cross-sectional dimensions of the support column 210 itself in the water stirring member 200, so that the clothes are guided to form a circular path around the water stirring member 200 during the washing process, which improves the washing effect and prevents the clothes from being entangled. In addition, the structure in which the first guide surface 213 extends upward obliquely and finally completely covers the lower surface of the water stirring plate 230 is adopted, and the position where the first guide surface 213 and the second guide surface 214 are connected is easier to contact the clothes during the washing process, thereby preventing the problem of a cleaning dead angle at this location.

[0138] Embodiment 3

[0139] like Figures 18 to 20 As shown, this embodiment is a further limitation of the above-mentioned embodiment 2, and 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, and 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 has a cavity arranged axially from the top end to the assembly portion 210-1.

[0140] 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.

[0141] 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.

[0142] In this embodiment, the support column 210 includes a mounting portion 210-1 and a hollow column 210-8 coaxially connected to the upper portion of the mounting portion 210-1. The mounting 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 mounting portion 210-1. The outer diameter of the connection between the hollow column 210-8 and the mounting portion 210-1 can be greater than the diameter of the mounting portion 210-1, or less than or equal to the diameter of the mounting portion 210-1; the outer peripheral wall of the hollow column 210-8 smoothly transitions with the outer peripheral wall of the mounting portion 210-1 and extends upward.

[0143] 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 disc 230 is provided at the top of the support column 210. The maximum diameter Dmax of the water stirring portion 240 is formed by the outer periphery of the water stirring disc 230. The top surface of the water stirring disc 230 is an upwardly convex curved surface. A cavity 210-9 similar to the outer shape of the support column 210 is formed inside the hollow column 210-8.

[0144] Preferably, the water stirring ribs 220 are also configured as hollow structures.

[0145] Further preferably, the internal space of the water stirring rib 220 is connected to the cavity 210-9 inside the hollow column 210-8.

[0146] 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 .

[0147] In this embodiment, the water stirring portion 240 is connected to the stirring shaft 300 rotatably passing through the bottom of the washing tub 100 through the assembly portion 210 - 1 , so that the water stirring member 200 can rotate relative to the washing tub 100 .

[0148] Specifically, the assembly portion 210 - 1 and the stirring shaft 300 are circumferentially positioned by splines and rotate together, and are axially positioned by screws 210 - 7 .

[0149] In this embodiment, the assembly portion 210-1 is provided with a spline groove 210-6 extending upwardly and coaxially from the bottom end surface of the assembly portion 210-1, and the spline groove 210-6 is at least partially sleeved on the upper end of the stirring shaft 300 and key-connected with the stirring shaft 300. The spline groove 210-6 is formed on the assembly portion 210-1 of the water stirring member 200.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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 .

[0154] 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.

[0155] The top of the flat plate portion and the top of the water stirring member 200 are in the same plane.

[0156] 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.

[0157] 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. Preferably, the bottom of the limiting protrusion is set as a conical surface with a gradually decreasing outer diameter from top to bottom, and the outer diameter of the bottom of the limiting protrusion is smaller than the inner diameter of the notch of the sealing groove 210-4.

[0158] 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.

[0159] 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 .

[0160] In this embodiment, a specific assembly structure of the water stirring member 200 and the stirring shaft 300 is provided. By setting the water stirring portion 240 of the water stirring member 200 to be hollow inside, the purpose of fixing the water stirring member 200 and the stirring shaft 300 by installing the screws 210-7 from top to bottom can be achieved, and the overall weight of the water stirring member 200 is also reduced, thereby further reducing the energy consumption of the motor of the driving device driving the water stirring member 200 to rotate. By setting the sealing cover 210-5, washing water can be prevented from entering the interior of the water stirring member 200, thereby preventing the problem of wire scraps or dirt entering with the washing water and remaining in the interior of the water stirring member 200 and being unable to be cleaned.

[0161] Embodiment 4

[0162] like Figures 18 to 20 As shown, this embodiment is a further limitation of the above-mentioned embodiment 2 or 3, and 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 center of the barrel bottom and is connected to the mounting portion 210-1.

[0163] 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.

[0164] In this way, the bottom surface of the washing tub 100 is substantially completely exposed to the washing space above, thus avoiding the problem of dirt and grime being collected at the bottom of the tub.

[0165] 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.

[0166] 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 .

[0167] 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, 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 .

[0168] 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, or slightly lower than the inner surface of the barrel bottom.

[0169] For the structure in which the upper end surface of the sealing structure 120 is slightly higher than the inner surface of the barrel bottom, no concave gap is formed between the dehydration shaft 110 and the stirring shaft 300. For the structure in which the upper end surface of the sealing structure 120 is slightly lower than the inner surface of the barrel bottom, 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.

[0170] As a specific embodiment, the lower end surface of the water stirring member 200, that is, the lower end surface of the assembly part 210-1, is at least partially arranged opposite to the upper end surface of the sealing structure 120. The assembly part 210-1 is sleeved on the upper end of the stirring shaft 300, and the lower end diameter of the assembly part 210-1 is larger than the diameter of the stirring shaft 300.

[0171] Furthermore, the diameter of the lower end of the fitting portion 210 - 1 is greater than the outer diameter of the sealing structure 120 .

[0172] In a specific embodiment, the difference between the lower end diameter 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.

[0173] In this embodiment, the specific assembly relationship between the bottom of the water stirring member 200, the stirring shaft 300 and the bottom of the barrel further ensures that no dirt or grime is hidden at the bottom of the barrel.

[0174] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
