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] Although the prior art also proposes a solution of setting the agitator as a stirring column, such as the technical solution disclosed in Chinese patent application CN201711031993.9, the stirring column only reduces the area covered by the bottom of the barrel, but cannot completely solve the problem that the gap between the agitator and the bottom of the barrel is easy to hide dirt.

[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 washing equipment, which can avoid the problem of dirt and grime accumulating between the water stirring component and the bottom of the washing tub.

[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 extends along the axial direction of the washing tub to have a certain length, and a stirring shaft for driving the water stirring member to rotate passes through the bottom of the washing tub and is connected to the lower end of the water stirring member;

[0010] A certain distance is formed between the lower end surface of the water stirring member and the inner surface of the bottom of the washing tub, and the certain distance enables the clothes to contact the lower end surface of the water stirring member.

[0011] Further, the bottom of the water stirring member has a mounting cavity with an open lower side, and the central area of ​​the bottom of the washing tub has a mounting portion for mounting the stirring shaft, and the stirring shaft rotatably passes through the mounting portion and is inserted into the mounting cavity;

[0012] The lower end surface of the water stirring member is arranged opposite to the mounting portion, and the spacing distance between the lower end surface of the water stirring member and the mounting portion enables the clothes to contact the area of ​​the lower end surface of the water stirring member close to the stirring shaft.

[0013] Furthermore, the area of ​​the barrel bottom extending outward from the mounting portion to the barrel wall of the washing barrel is a washing surface that can contact clothes during washing; the downward projection of the lower end surface of the water stirring member directly falls on the mounting portion or the washing surface.

[0014] Further, the mounting portion is flush with the washing surface; or, the mounting portion is protruding from the washing surface.

[0015] Furthermore, at a certain height upward from the lower end of the water-stirring member, the horizontal cross-section of the water-stirring member has a maximum radius along the radial direction of the washing tub;

[0016] A first washing space is formed between the lower end surface of the water stirring member and the bottom of the barrel, and a second washing space is formed between the maximum radius of the water stirring member and the lower end surface.

[0017] Further, the water stirring member includes an assembly portion formed by extending a certain length upward from the lower end surface, and a water stirring portion arranged above the assembly portion and connected to the assembly portion;

[0018] The maximum radius of the water stirring member is formed at the top, bottom, or middle area of ​​the water stirring portion; or, along the axial direction of the washing tub, a plurality of maximum radius points are formed on the water stirring portion at intervals.

[0019] Furthermore, the maximum radius of the water-stirring member is higher than the bottom of the water-stirring portion, and between the bottom of the water-stirring portion and the maximum radius, the horizontal cross-sectional radius of the water-stirring portion at least within a certain height range is smaller than the radius of the assembly portion.

[0020] Furthermore, the maximum radius of the water-stirring member is higher than the bottom of the water-stirring portion, and the radius of any horizontal cross-section of the water-stirring portion between the bottom of the water-stirring portion and the maximum radius is greater than or equal to the radius of the assembly portion.

[0021] Furthermore, the surface or partial surface of the stirring shaft is covered with an antibacterial layer, and the coverage of the antibacterial layer at least includes the area of ​​the stirring shaft between the lower end of the water stirring member and the inner surface of the barrel bottom.

[0022] A washing device comprises the washing barrel assembly of the washing device described above.

[0023] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0024] In the present invention, by setting a sufficient spacing distance between the lower end surface of the water stirring member and the inner surface of the bottom of the washing tub, the lower end surface of the water stirring member can be exposed in a space that can contact the laundry, so that when washing, the laundry contacts the lower end surface of the water stirring member, which can effectively prevent dirt from adhering to the lower end surface of the water stirring member, thereby avoiding the presence of a space between the lower end surface of the water stirring member and the inner surface of the bottom of the tub for harbouring dirt and grime. The lower end surface of the water stirring member is directly opposite to the inner surface of the bottom of the tub, and there is no impeller or other shielding structure between the two, which further ensures that the inner surface of the bottom of the tub will not harbor dirt and grime.

[0025] In the present invention, the water stirring member forms a horizontal cross section with the largest radius at a certain height from the lower end, and a first washing space and a second washing space are formed in an area below the maximum radius of the water stirring member. When washing, the clothes can contact the lower end surface of the water stirring member and the inner surface of the barrel bottom in the first washing space, and can fully contact the side of the water stirring member in the second washing space, which ensures that dirt is not easily attached to the surface of the water stirring member to the greatest extent. On the other hand, part of the clothes can be washed in the first washing space between the lower end surface of the water stirring member and the inner surface of the barrel bottom, and the clothes will not be completely covered on the water stirring member, which is conducive to reducing the energy consumption of the motor driving the water stirring member to rotate.

[0026] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[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 Figures 2 to 19 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.

[0055] 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 at least includes the above-mentioned washing tub assembly and a driving device, wherein the driving device is respectively connected to the washing tub 100 and the water stirring member 200 for driving the washing tub 100 and the water stirring member 200 to rotate.

[0056] More specifically, the driving device drives the washing tub 100 and the water stirring member 200 through a deceleration clutch device. The deceleration clutch device includes a stirring shaft 300 connected to the water stirring member 200, and a dehydration shaft 110 connected to the washing tub 100.

[0057] During the washing process, the deceleration clutch device performs the washing condition. Under the driving of the driving device, the stirring shaft 300 drives the water stirring member 200 to rotate, and the dehydration shaft 110 is fixed so that the washing tub 100 remains stationary, or the dehydration shaft 110 and the stirring shaft 300 rotate in the opposite direction to drive the washing tub 100 and the water stirring member 200 to rotate in the opposite direction, thereby utilizing 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, and achieve a cleaning effect on the clothes C. During the dehydration process, the deceleration clutch device performs the dehydration condition. Under the driving action of the driving device, the stirring shaft 300 and the dehydration shaft 110 rotate synchronously at a high speed, thereby driving the water stirring member 200 and the washing tub 100 to rotate synchronously at a high speed, and utilizing the centrifugal force to spin dry the clothes C in the tub.

[0058] However, the lint and dirt shed from the clothes C during the washing process are mixed into the washing water. If there is a large and 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. 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, especially between the lower end surface 210-11 of the water stirring member 200 and the bottom 100-3 of the washing tub 100, which is easy to breed bacteria and cause the problem of secondary pollution of clothes.

[0059] Embodiment 1

[0060] like Figure 2 and Figure 3 As shown, this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly, which is used to solve the problem that there is a dead corner between the lower end surface 210-11 of the water stirring member 200 and the bottom 100-3 of the washing tub 100, which is difficult to clean.

[0061] Specifically, the washing tub assembly of 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 along the axial direction of the washing tub 100 to have a certain length, and the stirring shaft 300 of the speed reduction clutch device passes through the bottom 100-3 of the washing tub 100 and is connected to the lower end of the water stirring member 200.

[0062] In this embodiment, after the water stirring member 200 and the stirring shaft 300 are installed in place, the lower end surface 210-11 of the water stirring member 200 has a certain distance from the inner surface of the barrel bottom 100-3 of the washing barrel 100, and the certain distance allows the clothes C to contact the lower end surface 210-11 of the water stirring member 200.

[0063] Specifically, the water stirring member 200 includes an assembly part 210-1 and a water stirring part 240. The assembly part 210-1 is extended upward from the lower end of the water stirring member 200 by a certain length, and its interior is hollow to form a mounting cavity with an open lower side. The upper end of the stirring shaft 300 is inserted into the mounting cavity and is key-connected with the assembly part 210-1, so as to drive the water stirring member 200 to rotate. The water stirring part 240 is connected to the upper end of the assembly part 210-1. When the water stirring member 200 rotates relative to the washing tub 100, the washing water and clothes in the tub can be stirred by the water stirring part 240. The lower end surface 210-11 of the water stirring member 200 is also the lower end surface 210-11 of the assembly part 210-1.

[0064] In the solution of this embodiment, by setting a sufficient spacing distance between the lower end surface 210-11 of the water stirring member 200 and the inner surface of the barrel bottom 100-3 of the washing barrel 100, the lower end surface 210-11 of the water stirring member 200 can be exposed in the washing space that can contact the clothes C during washing, and then through the contact between the clothes C and the lower end surface 210-11 of the water stirring member 200 during the washing process, it is possible to prevent the attachment of lint and dirt to the lower end surface 210-11 of the water stirring member 200. At the same time, through the above structure, the coverage area formed by the downward projection of the lower end surface 210-11 of the water stirring member 200 on the inner surface of the barrel bottom 100-3 can also contact the clothes during washing, thus effectively avoiding the problem of the existing washing equipment easily hiding dirt between the bottom surface of the stirring device and the barrel bottom.

[0065] In a further solution of this embodiment, the central area of ​​the bottom 100-3 of the washing barrel 100 has a mounting portion 100-2 for mounting the stirring shaft 300, and the stirring shaft 300 can be rotatably inserted into the mounting cavity inside the assembly portion 210-1 through the mounting portion 100-2. The mounting portion 100-2 is specifically a mounting through hole, and the stirring shaft 300 can be rotatably penetrated in the mounting through hole. The aperture of the mounting through hole is adapted to the diameter of the stirring shaft 300. Specifically, the aperture of the mounting through hole is slightly larger than the diameter of the stirring shaft 300, and the side wall of the stirring shaft 300 does not contact the outer periphery of the mounting through hole, ensuring that the rotation of the stirring shaft 300 is not affected.

[0066] After the water stirring member 200 and the stirring shaft 300 are assembled in place, the assembly portion 210-1 is located directly above the mounting portion 100-2, and the lower end surface 210-11 of the water stirring member 200 is arranged opposite to the mounting portion 100-2 of the barrel bottom 100-3. The certain interval between the lower end surface 210-11 of the water stirring member 200 and the inner surface of the barrel bottom 100-3, that is, the interval distance between the lower end surface 210-11 of the assembly portion 210-1 and the mounting portion 100-2. This interval distance allows the clothing C to contact the area of ​​the lower end surface 210-11 of the water stirring member 200 close to the stirring shaft 300.

[0067] In the above scheme, a first washing space is formed between the lower end surface 210-11 of the assembly part 210-1 and the bottom 100-3 of the washing barrel 100. By reserving a sufficient spacing distance between the lower end surface 210-11 of the assembly part 210-1 and the mounting part 100-2, the clothes in the first washing space can move toward the center area to the side wall of the stirring shaft 300 during washing, so that the lower end surface 210-11 of the assembly part 210-1 can contact the clothes at all places, avoiding the existence of cleaning dead corners that cannot contact the clothes and easily accumulate dirt.

[0068] Furthermore, the area of ​​the barrel bottom 100-3 extending outward from the mounting portion 100-2 to the barrel wall of the washing barrel 100 is the washing surface 100-31 that can contact clothes during washing, and the downward projection of the lower end surface 210-11 of the water stirring member 200 falls directly on the mounting portion 100-2 or the washing surface 100-31.

[0069] The projection directly falls on the mounting portion 100-2 or the washing surface 100-31, that is, there is no obstruction in the process of the lower end surface 210-11 of the water stirring member 200 being projected downward to the inner surface of the barrel bottom 100-3 of the washing tub 100. Specifically, between the lower end surface 210-11 of the water stirring member 200 and the inner surface of the barrel bottom 100-3, the side wall of the stirring shaft 300 is directly opposite to the barrel wall of the washing tub 100, and no impeller or other structures with a larger size extending radially along the washing tub 100 are arranged thereon.

[0070] With the above structure, the washing surface 100-31 of the barrel bottom 100-3 is completely exposed to the washing water during washing, and the clothes C in the first washing space can move along the washing surface 100-31, for example, along the washing surface 100-31 toward the center area to the side wall of the stirring shaft 300. In this way, the clothes can contact various parts of the barrel bottom 100-3, especially the area around the mounting portion 100-2, avoiding the existence of cleaning dead corners in the barrel bottom 100-3 that are easy to hide dirt.

[0071] As a specific embodiment, the mounting portion 100-2 is flush with the washing surface 100-31, that is, the inner surface of the barrel bottom 100-3 is a flat structure as a whole. When washing, the clothes C in the barrel are more easily moved along the washing surface 100-31 in the first washing space driven by the water flow, and gathered from the outer circumference to the stirring shaft 300.

[0072] As another specific implementation, Fig.17As shown, the mounting portion 100-2 is convexly arranged on the washing surface 100-31, so that the barrel bottom 100-3 forms a convex surface on the outer periphery of the mounting portion 100-2. In one detailed structure, the washing surface 100-31 extends downwardly from the outer periphery of the mounting through hole at an angle for a distance, and then extends horizontally to the barrel wall of the washing barrel 100. In another detailed structure, the washing surface 100-31 first extends horizontally from the outer periphery of the mounting through hole for a short distance, then extends downwardly at an angle for a distance, and then extends horizontally to the barrel wall of the washing barrel 100.

[0073] By adopting the above structure, an angle greater than 90° can be formed between the inner surface of the barrel bottom 100-3 and the side wall of the stirring shaft 300 on the periphery of the stirring shaft 300, making it easier to fully expose the area of ​​the washing surface 100-31 close to the mounting portion 100-2 and the area of ​​the side wall of the stirring shaft 300 close to the barrel bottom 100-3, thereby making it more conducive for the above-mentioned areas to contact with clothes and prevent the adhesion and accumulation of dirt.

[0074] In a specific solution of this embodiment, the washing surface 100-31 occupies 90% or more of the total area of ​​the bottom 100-3 of the washing tub 100, and preferably 95% or more of the total area of ​​the bottom 100-3 of the washing tub 100.

[0075] As a preferred solution of this embodiment, the surface or partial surface of the stirring shaft 300, especially the side wall of the stirring shaft 300, is covered with an antibacterial layer, and the coverage range of the antibacterial layer at least includes the area of ​​the side wall of the stirring shaft 300 between the lower end of the water stirring member 200 and the inner surface of the barrel bottom 100-3.

[0076] In the above solution, the side wall of the stirring shaft 300 is covered with an antibacterial layer at least in the area directly exposed to the washing water. The antibacterial layer can be formed by coating with an existing antibacterial coating, or by coating the side wall of the stirring shaft 300 with an antibacterial material, such as a flexible sheet made of an antibacterial material. In this way, even if a small amount of dirt remains on the side wall of the stirring shaft 300, the antibacterial layer can prevent bacteria from growing there, thereby avoiding secondary contamination of the clothes.

[0077] In a further solution of this embodiment, at a certain height upward from the lower end of the water stirring member 200, the horizontal cross section of the water stirring member 200 has a maximum radius along the radial direction of the washing tub 100, and a second washing space is formed between the maximum radius Rmax of the water stirring member 200 and the lower end surface 210-11 of the water stirring member 200. Specifically, the maximum radius Rmax of the water stirring member 200 is at least not lower than the top of the assembly portion 210-1.

[0078] During washing, as the water stirring member 200 and the washing tub 100 rotate relative to each other, the clothes C follow the water flow in a movement path: the clothes in the first washing space move along the washing surface 100-31 of the tub bottom 100-3 toward the central area to the side wall of the stirring shaft 300, rise along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the water stirring member 200, move toward the periphery along the lower end surface 210-11 of the water stirring member 200, continue to rise along the side of the water stirring member 200 to enter the second washing space, continue to rise to below the maximum radius Rmax of the water stirring member 200, and then move toward the periphery, and fall back to the bottom of the washing tub 100 in the area close to the barrel wall of the washing tub 100. In this way, the clothes C move around the water stirring member 200 along the outwardly turned circular path for washing, which can prevent the clothes from being entangled.

[0079] It should be noted that when the washing water level of the washing tub 100 is close to the height of the maximum radius Rmax of the water stirring member 200, the above-mentioned movement path is more likely to be formed. If the washing water level is lower than the maximum radius Rmax, the clothes C in the second washing space rise along the side of the water stirring member 200 to a height close to the washing water level, tend to move toward the periphery, and then fall back to the bottom of the washing tub 100.

[0080] In the embodiment of the present invention, the radius of the horizontal cross section of the water stirring member 200 refers to the radius of 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 horizontal cross section of the water stirring portion 240 is Figure 5 If the horizontal cross section of the stirring portion 240 is Figures 6 to 11 For the non-circular shape shown, the radius is the distance R2 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] Accordingly, in this embodiment and subsequent embodiments, the "diameter" mentioned refers to twice the radius size mentioned above.

[0083] The water stirring member 200 described in this embodiment has the above structure, and a first washing space and a second washing space are formed inside the washing tub 100. During washing, the clothes C can contact the lower end surface 210-11 of the water stirring member 200 and the inner surface of the tub bottom 100-3 in the first washing space, and can fully contact the side surface of the water stirring member 200 in the second washing space, which ensures that dirt is not easily attached to the surface of the water stirring member 200 to the greatest extent.

[0084] In addition, during washing, the clothes C mainly contact the lower end surface 210-11 and the side surface of the water stirring member 200. Different from the existing pulsator washing machine, during washing, the washing device of this embodiment mainly drives the clothes C to move in the barrel by the impact of the water flow generated by the water stirring member 200 stirring the washing water. The friction force of the water stirring member 200 on the clothes C only plays an auxiliary role, and the force directly applied by the water stirring member 200 to the clothes is greatly reduced, which is conducive to preventing the clothes C from getting entangled and reducing the wear on the clothes C. At the same time, compared with the washing method of the pulsator washing machine in which the clothes cover a large area on the surface of the pulsator, the contact area between the clothes C and the water stirring member 200 in this embodiment is reduced, and then the resistance to the rotation of the water stirring member 200 is reduced, which can reduce the motor energy consumption when the driving device drives the water stirring member 200 to rotate.

[0085] In this embodiment, further, the height of the maximum radius Rmax of the water stirring member 200 is set between the highest water level and the lowest water level of the washing device. During washing, when a washing water level higher than the maximum radius Rmax is used, after the clothes C rising along the side of the water stirring member 200 move to the maximum radius Rmax, they can continue to rise along the side of the water stirring member 200 until they are close to the height of the washing water level, and then move toward the periphery and then fall.

[0086] Furthermore, in this embodiment, the water stirring portion 240 includes a support column 210 extending upward along the axis from the upper end surface of the assembly portion 210-1, and a water stirring structure disposed on the side wall of the support column 210. Since a second washing space is formed between the maximum radius Rmax of the water stirring portion 240 and the lower end of the water stirring member 200 in the washing tub 100, the water stirring structure is at least disposed in a region lower than the maximum radius Rmax.

[0087] As a specific embodiment, the water stirring structure includes a water stirring rib 220 protruding from the side wall of the support column 210. 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 is inclined to the radial direction of the washing tub 100, and forms an angle less than 90° with the radial direction. 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.

[0088] Furthermore, the water stirring rib 220 has a certain extension length along the axial direction. Specifically, the lower end of the water stirring rib 220 can extend to a region not lower than the upper end of the assembly portion 210-1, and the assembly portion 210-1 is only used for the installation and fixation of the water stirring member 200 and the stirring shaft 300. Alternatively, the lower end of the water stirring rib 200 can also extend to the side wall of the assembly portion 210-1, and when the water stirring member 200 rotates, the washing water on the periphery of the assembly portion 210-1 can also be stirred by the water stirring rib 220.

[0089] 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. The clothes C can be washed in the interval area between two adjacent water-stirring ribs 220, so as to contact the two side surfaces of the water-stirring ribs 220 and the area of ​​the side wall of the support column 210 between the two water-stirring ribs 220, thereby avoiding the existence of a cleaning dead corner on the side wall of the support column 210 where dirt is easily attached.

[0090] The side surface of the water-stirring member 200 having the above structure includes both the side wall of the support column 210 and the surface of the water-stirring rib 220 that is farthest from the rotation axis, and the horizontal cross-sectional radius of the water-stirring member 200 within the water-stirring portion 240 is the distance between the farthest surface from the rotation axis on the water-stirring rib 220 and the rotation axis.

[0091] In the above structure, the radius of any horizontal section of the water stirring portion 240 specifically refers to the distance from the farthest end of the water stirring rib 220 from the axis to the central axis on the horizontal section. When the number of the water stirring ribs 220 is an even number, the length of the line connecting the farthest ends of two relative water stirring ribs 220 from the axis is the diameter of the horizontal section of the water stirring portion 240. When the number of the water stirring ribs 220 is an odd number, there are no relatively arranged water stirring ribs 220, and at this time the horizontal section of the water stirring portion 240 does not form an axisymmetric figure, but the diameter of the horizontal section of the water stirring portion 240 is still twice the radius determined above.

[0092] In another specific embodiment, the water stirring ribs extend spirally along the side wall surrounding the support column. In this case, the horizontal cross section of the water stirring portion may not form a regular geometric shape, but the radius of the horizontal cross section of the water stirring portion is still the distance from the farthest end of the water stirring ribs from the axis to the central axis on the cross section.

[0093] In this embodiment, the maximum radius Rmax of the water stirring member 200 can be formed at the top, bottom, or middle area of ​​the water stirring portion 240. The water stirring member 200 can have a single maximum radius Rmax, or multiple maximum radius Rmax can be arranged at intervals.

[0094] As a specific implementation of this embodiment, Figure 2 ,as well as Figure 12 to Figure 14 As shown, the water-stirring member 200 has a single maximum radius point Rmax in the height direction, and at least below the maximum radius point Rmax, the horizontal cross-sectional radius of the water-stirring portion 240 increases upward along the axis as the height increases.

[0095] In the first specific embodiment, if Fig.12As shown, the maximum radius Rmax of the water-stirring member 200 is set at the top of the water-stirring portion 240, that is, the top surface of the water-stirring portion 240 is the horizontal cross-section of the water-stirring member 200 with the maximum radius.

[0096] In the second specific scheme, if Figure 2 As shown, the maximum radius Rmax of the water stirring member 200 is close to the top of the water stirring portion 240, but is at a certain distance from the top of the water stirring portion 240. Specifically, the upper side surface of the water stirring portion 240 at the maximum radius Rmax is an upwardly convex curved surface, and the highest point of the curved surface forms the top of the water stirring member 200.

[0097] As a detailed solution, a plurality of water stirring ribs 220 are arranged on the side of the support column 210, and the radial dimension of the water stirring ribs 220 gradually increases from bottom to top, and the maximum radius Rmax of the water stirring member 200 is formed at the upper end. A water stirring plate 230 perpendicular to the axial direction is arranged at the upper end of the support column 210, and the upper side surface of the water stirring plate 230 is an upwardly convex curved surface.

[0098] In the third specific scheme, if Fig.13 and Fig.14 As shown, the maximum radius Rmax is located in the middle area of ​​the water stirring portion 240 along the height direction.

[0099] In a detailed scheme, Fig.13 As shown, the horizontal cross-sectional radius of the water stirring portion 240 changes continuously in the height direction. Specifically, as the height increases, the horizontal cross-sectional radius of the water stirring portion 240 gradually increases from the bottom to the top until the maximum radius Rmax is formed, and above the maximum radius Rmax, the horizontal cross-sectional radius of the water stirring portion 240 gradually decreases until the top of the water stirring member 200 is formed.

[0100] In another detailed scheme, Fig.14 As shown, the horizontal cross-sectional radius of the water stirring portion 240 has a sudden change at at least one height position. Specifically, as the height increases, the horizontal cross-sectional radius of the water stirring portion 240 first gradually increases from the bottom to the top, and when reaching a certain height, the radius suddenly increases to form the maximum radius Rmax; then the horizontal cross-sectional radius of the water stirring member 200 remains constant within a certain height range, and then suddenly decreases; thereafter, the horizontal cross-sectional radius of the water stirring portion 240 gradually decreases, and finally forms the top of the water stirring member 200.

[0101] In the above scheme, Fig.13 and Fig.14 The outer contour of the water stirring member 200 is shown. Fig.14Taking the structure shown as an example, a specific solution of the structure is to set a water-stirring rib extending from the lower end to the upper end on the support column, and the peripheral edge of the water-stirring rib on the side away from the axis extends upward along the outer contour of the water-stirring portion 240 in the figure, that is, it first tilts toward the periphery, then extends horizontally outward, then extends vertically, then extends horizontally inward, and finally extends obliquely toward the axis. Another specific solution of the structure can be to set a disc-shaped water-stirring structure perpendicular to the support column and having a certain thickness in the middle of the support column to form the maximum radius Rmax, and water-stirring ribs extending along the axial direction are respectively set on the upper and lower sides of the maximum radius Rmax on the side walls of the support column.

[0102] It should be understood that the above-mentioned structure is only used for illustration and is not intended to limit the present invention.

[0103] In this embodiment, when the water stirring member 200 has Figure 2 ,as well as Figure 12 to Figure 14 In the structure shown, if the washing device adopts a water level lower than the maximum radius Rmax for washing, a circular movement path of the clothes in the barrel is: the clothes move along the barrel bottom 100-3 toward the central area to the side wall of the stirring shaft 300, rise along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the water stirring member 200, move toward the periphery along the lower end surface 210-11 of the water stirring member 200, and then continue to rise along the side of the water stirring member 200 and approach the barrel wall. When rising to a height close to the maximum radius Rmax or the washing water level, the clothes move toward the periphery and finally fall back to the bottom of the washing barrel 100 from the area close to the barrel wall of the washing barrel 100.

[0104] for Fig.13 and Fig.14 In the structure shown, a third washing space is formed inside the washing tub 100 between the top of the water stirring member 200 and the maximum radius Rmax. If the washing device uses a water level higher than the maximum radius Rmax and lower than the top of the water-stirring member 200 for washing, one movement path of the clothes in the barrel is: the clothes move along the barrel bottom 100-3 toward the central area to the side wall of the stirring shaft 300, rise along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the water-stirring member 200, move toward the periphery along the lower end surface 210-11 of the water-stirring member 200, and then continue to rise along the side of the water-stirring member 200, and gradually approach the barrel wall. After reaching the maximum radius Rmax, part of the clothes moves toward the periphery and finally falls back to the bottom of the washing barrel 100 from the area close to the barrel wall of the washing barrel 100. Some of the clothes can also continue to rise along the side of the water-stirring member 200 to the third washing space and gradually approach the axis. After rising to a height close to the washing water level, this part of the clothes moves toward the periphery again and finally falls back to the bottom of the washing barrel 100 from the area close to the barrel wall of the washing barrel 100.

[0105] As another specific implementation, Fig.15 As shown, the water stirring member 200 has a unique maximum radius Rmax in the height direction, but below the maximum radius Rmax, as the height increases, the horizontal cross-sectional radius of the water stirring portion 240 increases and decreases alternately upward along the axis.

[0106] In detail, between the maximum radius Rmax and the bottom end of the water stirring portion 240, one or more radially protruding structures are provided. Along the axial direction upward, the horizontal cross-sectional radius of the water stirring portion 240 first gradually increases to the lowest protruding structure, then gradually decreases, and then gradually increases to the next protruding structure. After passing the protruding structure, it gradually decreases and then gradually increases until it finally increases to the maximum radius Rmax of the water stirring portion 240.

[0107] It is understandable that the above-mentioned protruding structure can be formed by the outer contour of the water-stirring rib itself, or can be formed by a plurality of disc-shaped water-stirring structures arranged perpendicular to the supporting column.

[0108] The water-stirring member 200 has the above-mentioned structure. When the washing device adopts a water level lower than the maximum radius Rmax for washing, a circular movement path of the clothes in the barrel is: the clothes move along the barrel bottom 100-3 toward the central area to the side wall of the stirring shaft 300, rise along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the water-stirring member 200, move toward the periphery along the lower end surface 210-11 of the water-stirring member 200, and then continue to rise along the side of the water-stirring member 200, and alternately approach the barrel wall and the axis during the rising process. When rising to a height close to the maximum radius Rmax or the washing water level, the clothes move toward the periphery and finally fall back to the bottom of the washing barrel 100 from the area close to the barrel wall of the washing barrel 100.

[0109] As another specific implementation method, Fig.16 As shown, the water stirring member 200 has a plurality of spaced maximum radius points Rmax in the axial direction of the washing tub 100. Specifically, as the height increases, the horizontal cross-sectional radius of the water stirring portion 240 increases and decreases alternately, each time increasing to the same radius size and then decreasing, thereby forming a plurality of spaced maximum radius points Rmax.

[0110] In the above scheme, when the washing equipment uses a water level lower than the top of the water-stirring component 200 for washing, a circular movement path of the clothes in the barrel is: the clothes move along the barrel bottom 100-3 toward the central area to the side wall of the stirring shaft 300, rise along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the water-stirring component 200, move toward the periphery along the lower end surface 210-11 of the water-stirring component 200, and then continue to rise along the side of the water-stirring component 200. During the rising process, the clothes alternately approach the barrel wall and the axis, and the distance approaching the barrel wall each time is basically the same. When rising to a point close to the maximum radius Rmax or the washing water level, the clothes move toward the periphery and finally fall back to the bottom of the washing barrel 100 from the area close to the barrel wall of the washing barrel 100.

[0111] It is understandable that the maximum radius of the water stirring member may also be set at the bottom of the water stirring portion, and above the maximum radius, the horizontal cross-sectional radius of the water stirring portion decreases with increasing height.

[0112] In a further solution of this embodiment, for a structure in which the maximum radius Rmax of the water stirring member 200 is higher than the bottom end of the water stirring portion 240, the assembly portion 210-1 forms a minimum radius section of the water stirring member 200 that is lower than the area of ​​the maximum radius Rmax. Specifically, between the bottom end of the water stirring portion 240 and the maximum radius Rmax, the radius of any horizontal cross section of the water stirring portion 240 is greater than or equal to the radius of the assembly portion 210-1.

[0113] In the above solution, the second washing space has a maximum radial dimension at the outer periphery of the assembly portion 210-1, and the area of ​​the lower end surface 210-11 of the assembly portion 210-1 is relatively small, that is, the bottom of the water stirring member 200 does not have a disc-shaped stirring portion, so that the clothes are more likely to fully contact with the lower end surface 210-11 of the assembly portion 210-1. At the same time, the clothes in the first washing space that rise along the side wall of the stirring shaft 300 with the water flow are more likely to pass over the lower end surface 210-11 of the assembly portion 210-1 and enter the second washing space.

[0114] Furthermore, the distance between the maximum radius Rmax of the water stirring portion 240 and the upper end of the assembly portion 210-1 is greater than the extension length of the assembly portion 210-1 along the axial direction of the washing tub 100. Preferably, the distance between the maximum radius Rmax of the water stirring portion 240 and the upper end of the assembly portion 210-1 is several to more than ten times the axial length of the assembly portion 210-1 along the washing tub 100. In this way, it is ensured that the second washing space formed below the maximum radius Rmax is large enough.

[0115] As a specific solution of this embodiment, Figure 2As shown, the water stirring portion 240 further includes a water stirring plate 230 disposed at the upper end of the support column 210, and the outer periphery of the water stirring plate 230 forms the maximum radius Rmax of the water stirring portion 240. The water stirring ribs 220 extend upward to the lower surface of the water stirring plate 230 to prevent the existence of a dead corner between the water stirring ribs 220 and the water stirring plate 230 that cannot contact the clothes and is easy to hide dirt.

[0116] 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. Similarly, 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.

[0117] As a specific solution, Figure 2 As shown, the side wall of the support column 210 extends in the vertical direction or close to the vertical direction, and the radial dimension of the water-stirring rib 220 along the washing tub 100 increases with the increase of the height. The upper end of the water-stirring rib 220 is away from the side of the support column 210 and coincides with the outer periphery of the water-stirring plate 230, so that the radial dimension of the water-stirring rib 220 along the washing tub 100 is maximized as much as possible, which can enhance the agitation of the washing water and enhance the washing effect.

[0118] In a further solution, the peripheral edge of the water stirring rib 220 away from the axis is a curved surface that extends. Specifically, in this embodiment, the peripheral edge of the water stirring rib 220 away from the axis extends upward at a certain angle to the horizontal direction. In the lower area, the acute angle between the water stirring rib 220 and the horizontal direction increases with the increase in height, forming a curved surface that bends away from the axis. After extending beyond a certain height, the acute angle between the water stirring rib 220 and the horizontal direction decreases with the increase in height, forming a curved surface that bends toward the axis, and finally extends to the periphery of the water stirring plate 230.

[0119] In this embodiment, the outer edge of the water stirring rib 220 is a curved surface extending upward. During the washing process, the rotation of the water stirring member 200 can drive the washing water to produce a flow trend that conforms to the curved surface, so that in the second washing space, the clothes can be driven to produce a movement trend of rising along the outer edge of the water stirring rib 220, and the clothes are guided to move toward the periphery after the clothes rise with the water flow to a point close to the maximum radius Rmax. In this way, the turning movement of the clothes in the barrel is strengthened, the washing effect can be enhanced, and at the same time, the clothes can be prevented from excessively gathering toward the center and causing entanglement.

[0120] In addition, in this embodiment, when the washing machine adopts low water level washing, the clothes will not rise above the water stirring plate 230, and thus will not have large-area contact and friction with the water stirring member 200. When washing at a high water level that covers the water stirring plate 230, since the diameter of the water stirring plate 230 is much smaller than the inner diameter of the washing tub 100, rather than the radial dimension of the impeller in the pulsator washing machine being close to the tub diameter, even if some clothes are covered on the upper side of the water stirring plate 230, the contact area between the clothes and the water stirring member 200 is greatly reduced compared with the contact area between the clothes and the impeller in the pulsator washing machine, and does not affect the effect of reducing clothes entanglement, reducing clothes wear, and reducing the energy consumption of the driving device motor in this embodiment.

[0121] In this embodiment, a sufficient spacing distance is reserved between the lower end surface 210-11 of the water-stirring member 200 installed in the washing barrel 100 and the inner surface of the barrel bottom 100-3. During the washing process, the clothes can contact the lower end surface 210-11 of the water-stirring member 200 and the area where the side wall of the stirring shaft 300 is located between the lower end surface 210-11 of the water-stirring member 200 and the inner surface of the barrel bottom 100-3, thereby avoiding the problem of dirt and grime accumulating between the lower end surface 210-11 of the water-stirring member 200 and the barrel bottom 100-3.

[0122] The water-stirring member 200 forms a horizontal section with a maximum radius at a position higher than the lower end surface 210-11, and the clothes can be washed below the maximum radius Rmax of the water-stirring member 200. On the one hand, the clothes can be in contact with the surface of the water-stirring member 200 to prevent dirt from adhering. On the other hand, the clothes are prevented from being completely covered on the water-stirring member 200, which has the effects of reducing entanglement of clothes, alleviating wear of clothes, and reducing energy consumption of the motor of the driving device.

[0123] Embodiment 2

[0124] like Fig.17 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that the water stirring portion 240 has a horizontal cross section between its bottom end and the maximum radius Rmax, the radius of which is smaller than the radius of the assembly portion 210 - 1 .

[0125] Specifically, between the bottom end of the water stirring portion 240 and the maximum radius Rmax, the radius of the horizontal section of the water stirring portion 240 at least within a certain height range is smaller than the maximum radius of the mounting portion 210 - 1 .

[0126] As a specific embodiment, the radius of the assembly portion 210-1 gradually increases with the increase of height, thereby forming a smooth rounded transition between the lower end surface 210-11 of the assembly portion 210-1 and the side wall, so that the clothes in the first washing space below the lower end surface 210-11 of the assembly portion 210-1 can be more easily raised to the second washing space.

[0127] Furthermore, the horizontal cross-sectional radius of the water stirring portion 240 gradually decreases upward from the bottom end connected to the assembly portion 210 - 1 until a horizontal cross-sectional radius of the minimum is formed, and then gradually increases with increasing height until the maximum radius Rmax of the water stirring member 200 is formed.

[0128] It is understandable that the horizontal cross section with the smallest radius refers to the horizontal cross section with the smallest radius located below the maximum radius Rmax. For a solution in which the maximum radius Rmax is not disposed at the top of the water stirring portion 240, the water stirring portion 240 may also have a horizontal cross section with a smaller radius above the maximum radius Rmax.

[0129] In a detailed structure, the above-mentioned variation trend of the horizontal cross-sectional radius of the water stirring portion 240 is formed by the water stirring rib 220. Specifically, the diameter of the support column 210 along the axial direction remains consistent, the water stirring rib 220 is arranged on the side wall of the support column 210, and the radial dimension of the water stirring rib 220 first decreases and then increases with the increase of the height, so that within a certain height range, the radius of the water stirring portion 240 is smaller than the radius of the assembly portion 210-1.

[0130] In a further solution of this embodiment, the bottom 100-3 has a raised surface on the outer periphery of the mounting portion 100-2, so that the mounting portion 100-2 is convexly disposed on the washing surface 100-31. Specifically, the washing surface 100-31 extends outward from the mounting through hole, starts from the outer periphery of the mounting through hole, or starts to extend obliquely downward from a certain distance from the outer periphery of the mounting through hole, and then extends horizontally to connect with the barrel wall of the washing barrel 100.

[0131] In this embodiment, the assembly part 210-1 has a larger radius, and thus the area of ​​the lower end surface 210-11 of the assembly part 210-1 is larger. The barrel bottom 100-3 is set to a structure in which the central area is raised relative to the peripheral area, so that clothes can more easily enter the interval area between the lower end surface 210-11 of the assembly part 210-1 and the inner surface of the barrel bottom 100-3, ensuring that the clothes can contact the lower end surface 210-11 of the assembly part 210-1, especially the area close to the center of the lower end surface 210-11 of the assembly part 210-1.

[0132] It is understandable that the bottom 100-3 of the washing tub 100 in this embodiment may also be formed as follows: Figure 2 However, compared with the structure in which the central area of ​​the barrel bottom 100-3 is convex, when the barrel bottom 100-3 is set as an overall planar structure, the spacing distance between the lower end surface 210-11 of the assembly part 210-1 and the installation part 100-2 needs to be set larger.

[0133] In this embodiment, when the washing device uses a water level lower than the maximum radius Rmax of the water stirring member 200 for washing, the water stirring member 200 and the washing tub 100 rotate relative to each other, driving the clothes to follow the water flow in a movement path as follows:

[0134] The clothes move toward the center along the washing surface 100-31 of the bottom 100-3 of the washing tub 100 in the bottom area, move to the side wall of the stirring shaft 300, and then move upward along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the water-stirring member 200; the clothes here move toward the periphery along the lower end surface 210-11 of the water-stirring member 200, and after moving to a point beyond the coverage of the lower end surface 210-11 of the water-stirring member 200, continue to rise along the side of the water-stirring member 200; during the rising process of the clothes, after exceeding the top of the assembly part 210-1, a movement trend toward the central axis is generated, and then after moving obliquely upward toward the central axis for a certain distance, the clothes continue to rise obliquely toward the peripheral direction; the clothes can rise to below the maximum radius Rmax of the water-stirring member 200 or the height of the washing water level, and then move toward the periphery, and finally fall along the barrel wall of the washing tub 100 to the barrel bottom 100-3.

[0135] In this embodiment, the assembly portion 210-1 of the water stirring member 200 is no longer the minimum diameter section of the water stirring member 200 below the maximum radius Rmax area, but at a certain height above the assembly portion 210-1, the water stirring portion 240 first forms a minimum radius, and then continues upward to form the maximum radius Rmax. The radius size of the part of the water stirring member 200 close to the barrel bottom 100-3 is increased, which can strengthen the stirring force of the washing water in the bottom area of ​​the washing barrel 100, enhance the water flow intensity in the first washing space, and then better flush the lower end surface 210-11 of the water stirring member 200 and the inner surface of the barrel bottom 100-3 to prevent dirt from adhering.

[0136] Embodiment 3

[0137] like Figures 18 to 20 As shown, this embodiment provides a specific structure of a water stirring member 200 based on the above-mentioned embodiment 1.

[0138] Specifically, the water stirring member 200 of this embodiment includes a mounting portion 210-1 extending vertically upward from the lower end to a certain height, and a water stirring portion 240 located above the mounting portion 210-1 and connected to the upper end of the mounting portion 210-1. The water stirring portion 240 specifically includes: a support column 210 extending upward from the top end of the mounting portion 210-1, a water stirring rib 220 protruding radially or nearly radially on the side wall of the support column 210, and a water stirring disc 230 arranged at the top end of the support column 210.

[0139] As a specific embodiment, the top surface of the water stirring plate 230 is an upwardly convex curved surface. In a preferred embodiment, a convex stirring portion 231 is provided on the curved surface for rubbing against the clothes above and stirring the washing water when washing at a higher water level, thereby enhancing the washing effect.

[0140] In a specific solution of this embodiment, the upper end of the stirring shaft 300 is keyed to the assembly portion 210-1 to achieve circumferential positioning between the water stirring member 200 and the stirring shaft 300, so that the rotation of the stirring shaft 300 can drive the water stirring member 300 to rotate synchronously. After the assembly portion 210-1 is mounted on the upper end of the stirring shaft 300, the assembly portion 210-1 is axially limited by screws with the upper end of the stirring shaft 300.

[0141] In a detailed structure, an assembly hole 210-3 is provided on the water stirring member 200, which penetrates the water stirring member 200 in the axial direction. A screw is inserted from the upper end of the assembly hole 210-3 and tightened on the stirring shaft 300 to axially limit the water stirring member 200. A sealing groove 210-4 communicating with the assembly hole 210-3 is provided at the top of the water stirring member 200. A sealing cover 210-5 for sealing the upper end of the water stirring member 200 is provided at the sealing groove 210-4 to prevent washing water from entering the interior of the water stirring member 200.

[0142] Specifically, the sealing groove 210-4 is arranged at the center of the water stirring plate 230, the support column 210 is an internal hollow structure, and an assembly hole 210-3 communicating with the sealing groove 210-4 is formed inside the support column 210. In a preferred structure, the support column 210 and the water stirring rib 220 are integrally an internal hollow structure, and the assembly portion 210-1 at the bottom is a solid structure, so that the center of gravity of the water stirring member 200 is lower than half of its height.

[0143] More specifically, the sealing cover 210-5 includes a flat plate portion and an insertion 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 insertion portion is inserted into the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0144] As a preferred structure, the top of the flat plate portion and the top of the water stirring member 200 are in the same plane.

[0145] The sealing groove 210-4 specifically includes a first section and a second section whose diameters increase from top to bottom. The lower end of the insertion portion is provided with a limiting protrusion protruding from the outer wall of the lower end of the insertion portion in a direction away from the central axis, and the limiting protrusion is engaged at the junction between the first section and the second end.

[0146] As a preferred structure, 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 tilts from top to bottom away from the central axis, 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 fits with the inner wall of the second section, and the top of the limiting protrusion fits 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.

[0147] In this embodiment, a sealing ridge extending along the circumference of the inserting portion is provided in the middle of the inserting portion, and the inserting 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 inserting portion and is provided with multiple circles spaced apart along the axial direction of the inserting portion.

[0148] Further preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the central axis to improve the smoothness of the insertion of the sealing cover 210-5.

[0149] In this embodiment, the maximum radius Rmax of the water stirring member 200 is formed by the outer periphery of the water stirring plate 230. Below the water stirring plate 230, the radial dimension of the support column 210 remains constant or gradually increases with increasing height, thereby forming a guiding surface for guiding the movement of clothes during washing.

[0150] Specifically, in this embodiment, the support column 210 extends from bottom to top and sequentially includes a first extension section 211 and a second extension section 212. The side wall of the first extension section 211 extends upward from the upper end of the assembly portion 210-1. The side wall of the second extension section 212 extends from the upper end of the first extension section 211 to the periphery and tilts upward, and finally extends to the height where the radius Rmax of the water stirring portion 240 is the maximum, that is, extends to the lower surface of the water stirring plate 230.

[0151] It should be noted that the side wall of the first extension section 211 extends upward from the upper end of the assembly portion 210-1, and can be extended vertically upward, or extended upward at an angle relative to the vertical direction, gradually approaching or moving away from the barrel wall of the washing barrel 100, or can be extended upward along a curve with a larger curvature and gradually approaching or moving away from the barrel wall of the washing barrel 100.

[0152] 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 is inclined at a larger angle to the vertical direction than the side wall of the first extension section 211, and as the height increases, the inclination 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.

[0153] 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 .

[0154] Furthermore, in this embodiment, the guide surface includes a first guide surface 213 formed by the side wall of the second extension section 212, which is used to guide the clothes rising from the central area of ​​the washing tub 100 to the bottom of the central area to move toward the periphery along the first guide surface 213 during washing. The guide surface also includes a second guide surface 214 formed by the side wall of the first extension section 211, which is used to guide the clothes to rise from the second guide surface 214 to the first guide surface 213 during washing.

[0155] Specifically, the water stirring member 200 provided in this embodiment is applied to the washing device. During washing, the water stirring member 200 rotates relative to the washing tub 100, and the clothes can move along the bottom 100-3 of the washing tub 100 toward the central area, and then rise along the side wall of the stirring shaft 300 to the lower end surface 210-11 of the assembly part 210-1, move toward the periphery along the lower end surface 210-11, and then move upward along the side wall of the assembly part 210-1 and the second guide surface 214 to the first guide surface 213, move toward the periphery under the guidance of the first guide surface 213, 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 strengthened to improve the washing effect, and on the other hand, the probability of the clothes concentrating toward the center and getting entangled is reduced.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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 surface of the water stirring rib 220 extends from bottom to top, and the acute angle between the extension direction and the vertical direction gradually decreases, so that the peripheral edge surface of the water stirring member 200 forms a curved surface that bends toward the barrel wall of the washing tub 100. The upper end of the peripheral edge surface of the water stirring rib 220 coincides with the outer periphery of the water stirring tray 230.

[0162] 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.

[0163] It can be understood that during washing, the clothes that move toward the periphery along the lower end surface 210-11 of the assembly part 210-1 and then rise can also be lifted along the outer edge of the water-stirring rib 220 after contacting the water-stirring rib 220. After moving to the maximum radius Rmax of the water-stirring part 240, they move toward the periphery under the action of inertia and centrifugal force, and finally fall along the wall of the washing barrel 100 to the bottom 100-3 of the barrel.

[0164] In the preferred scheme of this embodiment, 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.

[0165] 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.

[0166] In this embodiment, by designing the specific structure of the water-stirring component 200, the side wall of the support column 210 is used to form a guiding surface that can guide the movement of clothes. Combined with the specific structure of the water-stirring rib 220, the effect of driving the clothes to move along a circular path below the maximum radius Rmax is better.
