Description

Technical Field

[0001] The present invention belongs to the field of washing equipment, and more specifically, relates to a water-stirring member and a washing tub assembly of a washing equipment. Background Art

[0002] As a convenient clothing cleaning equipment, washing machines have been widely used in people's lives. Existing washing machines are divided into drum washing machines and pulsator washing machines. Among them, pulsator washing machines are favored by a large number of users due to their good cleaning effect.

[0003] A pulsator washing machine usually includes a washing inner tub and a pulsator. The pulsator is arranged at the bottom of the washing inner tub. When the pulsator washing machine works, the rotation of the pulsator drives the washing water in the inner tub to rotate, so as to realize the washing of the clothes to be cleaned in the inner tub.

[0004] During the washing process, the clothes are in contact with and rubbed against the pulsator. Since the pulsator is generally made of plastic, the friction force on the clothes is relatively large, which easily causes the surface of the clothes to form lint balls, especially for clothes made of certain materials that are prone to linting.

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

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a water-stirring member and a washing tub assembly of a washing equipment, which have less friction on clothes and make the clothes not easy to form lint balls.

[0007] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] On the one hand, a water-stirring member of a washing equipment is provided.

[0009] The water-stirring member includes a support column with a certain extension length, and a water-stirring disk extending towards one end of the support column at a certain length of the support column; at a certain extension position of the water-stirring disk, there is a maximum radius section, and there is a distance between the maximum radius section and the other end of the support column;

[0010] At least part of the outer surface of the water-stirring member is wrapped with a flexible material.

[0011] Further, a number of water-stirring ribs are arranged on the support column. The inner edge of the water-stirring rib extends along the axial direction of the support column, and the outer edge extends radially outward along the support column;

[0019] At least part of the outer surface of the water stirring rib is wrapped with a flexible material.

[0020] On the other hand, a washing tub assembly including the water stirring member of the above washing device is also provided.

[0021] The washing tub assembly includes a washing tub.

There is a gap between the maximum radius section and the inner surface of the bottom of the tub, and the clothes can be washed within this gap.

[0022] Further, the support column extends upward from the top end of the assembly part coaxially arranged with the bottom of the tub;

[0023] The bottom of the washing tub has a groove-like structure extending downward. The assembly part is arranged in the groove-like structure, and its upper end protrudes from the groove-like structure higher than the inner surface of the bottom of the tub or is flush with the inner surface of the bottom of the tub. The radius of the groove-like structure is slightly larger than the radius of the assembly part;

[0024] An installation opening is provided at the bottom surface of the groove-like structure. The stirring shaft passes through the installation opening and is inserted into the assembly part to be connected with the water stirring member;

[0025] The part of the outer periphery of the assembly part protruding from the groove-like structure higher than the inner surface of the bottom of the tub is wrapped with a flexible material.

[0026] Further, several water stirring ribs are arranged at intervals on the outer periphery of the support column. The outer edge of the water stirring rib is provided with a flexible material, and the projection perpendicular to the bottom of the tub at any position on the outer edge is directly located on the inner surface of the bottom of the washing tub.

[0060] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" 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 those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] As Figures 1 to 17 shown, the present invention provides a water-stirring member and a washing tub assembly for a washing device.

[0062] On the one hand, a water-stirring member for a washing device is provided.

[0063] The water-stirring member includes a support column with a certain extended length, and a water-stirring disk extending towards one end of the support column at a certain length of the support column; a maximum radius section is provided at a certain extended position of the water-stirring disk;

[0064] At least part of the outer surface of the water-stirring member is wrapped with a flexible material 260.

[0065] For the water-stirring member provided by the present invention, since its outer surface is wrapped with the flexible material 260, the friction between the water-stirring member and the clothes is small, and the clothes are not easily fuzzed.

[0066] On the other hand, a washing tub assembly including the above-mentioned water-stirring member of the washing device is also provided.

[0067] The washing tub assembly includes a washing tub.

[0068] For the washing tub assembly provided by the present invention, since it includes the above-mentioned water-stirring member, during the washing process of the clothes, water flow can enter the gap to wash away stains, avoiding dirt accumulation between the water-stirring member and the bottom of the tub. This solution improves the user experience.

[0069] Embodiment 1

[0070] As Figure 1 and Figure 2 shown, this embodiment provides a water-stirring member for a washing device.

[0071] The water-stirring member includes a support column with a certain extended length, and a water-stirring disk extending towards one end of the support column at a certain length of the support column; a maximum radius section is provided at a certain extended position of the water-stirring disk;

[0072] At least a part of the outer surface of the water stirring member is wrapped with a flexible material 260.

[0073] The water stirring member provided in this embodiment is arranged in the washing tub of the washing machine to drive the washing water to rotate, so as to realize the washing of the clothes in the washing tub.

[0074] The water stirring member includes a support column and a water stirring disc. The support column has a certain extension length, one end of which is matched with the bottom of the washing tub, and the other end extends towards the mouth of the washing tub. One end of the water stirring disc is arranged at any height of the support column, and the other end extends above the washing tub. The water stirring disc has a maximum radius section, and this maximum radius section can be located at any extension height of the water stirring disc.

[0075] In the solution of this embodiment, a flexible material 260 is wrapped on the outer surface of the water stirring member. Thus, the friction between the water stirring member and the clothes is small, and the clothes are not easy to fuzz.

[0076] Since one end of the water stirring disc is arranged at any height of the support column, the other end extends above the washing tub, and the maximum radius section can be at a certain extension position. That is to say, the water stirring disc has a certain thickness, and the maximum radius section is at this arbitrary thickness. The shape of the water stirring disc can be a candied fruit-like structure or an umbrella surface-like structure. Of course, it can also be other shapes. In the solution of this embodiment, the specific shape is not limited. As long as it can stir the water flow to rotate.

[0077] It should be noted that in the embodiment of the present invention, the maximum radius section refers to the radius of the horizontal section of the water stirring part 240. The water stirring part 240 takes a section along the horizontal direction (see Figure 10 ), and the distance from the point farthest from the rotation center to the rotation center on the obtained horizontal section.

[0078] Specifically, if the horizontal section of the water stirring part 240 is Figure 11 the shown circle, then the radius mentioned above is the radius R1 of this circular section. If the horizontal section of the water stirring part 240 is Figures 12 to 17 the shown non-circle, then the radius mentioned above is the distance R2 from the point farthest from the rotation center to the rotation center (i.e., the position marked by "×" in the figure) on this section.

[0079] The solution of this embodiment further includes: a plurality of water stirring ribs are arranged on the support column, the inner edge of the water stirring rib extends along the axial direction of the support column, and the outer edge extends radially outward along the support column;

[0080] At least a part of the outer surface of the support column and / or the water stirring rib is wrapped with a flexible material.

[0081] In the middle area of the upper part of the water stirring disc, there is a sealing cover 210-5 higher than the upper surface, and the outer peripheral area of the sealing cover is a curved surface extending downward;

[0082] The sealing cover is made of flexible material and / or the outer peripheral area of the sealing cover is wrapped with flexible material 260.

[0083] A number of raised stirring parts are arranged on the curved surface;

[0084] The stirring part has a certain extension length, one end of which is arranged near the central area of the upper surface of the water stirring disc, and the other end extends towards the edge direction of the water stirring disc;

[0085] The outer surface of the stirring part is wrapped with flexible material 260.

[0086] Next, the specific structure of the water stirring component will be introduced in detail:

[0087] The water stirring component includes a support column 210 coaxially arranged with the bottom of the barrel, a water stirring rib 220 arranged on the outer periphery of the support column 210, and a water stirring disc 230 arranged at the end of the support column 210. That is to say, one end of the support column 210 is cooperatively connected with the bottom of the barrel, and the other end extends towards the barrel mouth, and a water stirring disc 230 is arranged at its extended end. The water stirring rib 220 extends obliquely upward from the outer periphery of the end of the support column 210 away from the water stirring disc towards the upper part of the washing barrel 100.

[0088] In a specific solution of this embodiment, the support column 210 is a cylindrical structure, and the radius of this cylindrical structure is the same along its extending direction.

[0089] In another specific solution of this embodiment, the support column 210 includes two parts, namely a connected first extension section 211 and a second extension section 212. Among them, the first extension section 211 extends upward from the bottom of the washing barrel 100, and its side wall forms a second guiding surface 214. The second extension section 212 extends upward from the first extension section 211, and the radius of the second extension section 212 gradually increases with the increase of height, and its side wall forms a first guiding surface 213. That is to say, the radii of the first extension section 211 and the second extension section 212 are not the same. The radius of the first extension section 211 remains unchanged, and the radius of the second extension section 212 gradually becomes larger with the increase of height. By setting the first extension section 211 and the second extension section 212, the included angle between the side wall at the upper end of the support column 210 and the lower surface of the water stirring disc 230 is greatly increased, thereby effectively reducing the problem of cleaning dead corners where clothes cannot be reached between the upper end of the support column 210 and the lower surface of the water stirring disc 230. And in this solution, the contact area between the end cover and the support column 210 is increased, making the two fixed more firmly.

[0090] In the above solution, the outer periphery of the support column is wrapped with flexible material 260, thereby further reducing the friction with clothes.

[0091] In this embodiment, the water stirring rib 220 is a plate-like structure with one end arranged on the support column 210 along the extending height direction of the support column 210 and the other end extending outward along the radial direction of the support column 210.

[0092] It should be noted that at different height positions of the support column 210, the extending lengths of the water stirring ribs 220 are different. That is to say, the outer contour of the water stirring ribs 220 is arc-shaped. And a flexible material 260 is wrapped around the outer contour, thereby further reducing the friction with the clothes.

[0093] More notably, in this solution, the water stirring rib 220 first extends obliquely towards the edge of the barrel mouth of the washing barrel 100 and then tends to extend parallel to the support column 210 above the barrel mouth of the washing barrel 100 at the extending end. And the extending end abuts against the water stirring disc 230. In the above preferred solution, the initial inclination angle is the angle between the bottom of the washing barrel 100 and the straight line connecting the end of the water stirring rib 220 and the edge of the barrel mouth of the washing barrel 100.

[0094] In the specific solution of this embodiment, the water stirring member 200 includes a plurality of water stirring ribs 220, and the plurality of water stirring ribs 220 are arranged at equal intervals along the circumferential direction of the support column 210. The ends of the water stirring ribs 220 at the same height position of the support column 210 enclose a circle, and along the upward extending direction of the support column 210, the radius of the circle enclosed by the ends of the water stirring ribs 220 increases. Among them, the radius of the circle enclosed by the ends of the water stirring ribs 220 can increase gradually, or increase first and then decrease, or the radius change range is smaller at first and then larger.

[0095] For example, the dimension of the water stirring rib 220 along the radial direction of the washing barrel 100 first increases and then decreases from the lower end to the upper end. As a specific implementation manner, the cross-sectional shape of the water stirring rib 220 along the direction parallel to the radial direction of the washing barrel 100 is approximately spindle-shaped, and the outer peripheral edge of the water stirring rib 220 extends from bottom to top, and the included angle between the extending direction and the vertical direction gradually decreases, so that the outer peripheral edge of the water stirring member 200 forms a curve bending towards the barrel wall of the washing barrel 100. The upper end of the outer peripheral edge of the water stirring rib 220 coincides with the outer circumference of the water stirring disc 230. In this solution, the number of water stirring ribs can be set according to requirements.

[0096] In this solution, the upper surface of the water stirring rib abuts against the inner surface of the water stirring disc, and the abutting area of the two is wrapped with a flexible material 260. Also, since the water stirring rib is a plate-like structure, the outer edge and both side surfaces of the water stirring rib are wrapped with a flexible material 260. That is to say, in this solution, the areas where the water stirring rib contacts the clothes are all wrapped with a flexible material 260. Thereby further reducing the friction between it and the clothes.

[0097] Since the water stirring rib 220 has the above structure, the Coanda effect can be formed during washing, driving the water flow to flow along the outer peripheral edge of the water stirring rib 220, so that in the area near the axis of the washing tub 100, the water flow has a tendency to flow along the outer peripheral edge of the water stirring rib 220. As the height increases, the flow direction of the water flow is closer to upward rather than flowing outward. In this way, the lifting force of the water flow on the clothes in the area near the axis can be enhanced, driving the clothes to move upward along the second guiding surface 214 to the first guiding surface 213 and finally forming an annular movement path.

[0098] It can be understood that the clothes moving from the bottom of the tub to the central area can also be lifted along the outer peripheral edge of the water stirring rib 220 after contacting the water stirring rib 220. After moving to the maximum radius section Dmax of the water stirring member 200, they move outward under the action of inertia and centrifugal force and finally fall along the wall of the washing tub 100 to the bottom of the tub.

[0099] Of course, in other solutions of this embodiment, only one water stirring rib 220 can be provided, and the water stirring rib 220 is spirally wound around the outer surface of the support column 210.

[0100] In the above structure, the radius of any horizontal section of the water stirring part 240 specifically refers to the distance from the farthest end of the water stirring rib 220 from the axis to the central axis on this horizontal section. When the number of water stirring ribs 220 is even, the length of the connection line between the farthest ends of the two opposite water stirring ribs 220 from the axis is the diameter of the horizontal section of the water stirring part 240. When the number of water stirring ribs 220 is odd, there are no opposite water stirring ribs 220. At this time, the horizontal section of the water stirring part 240 does not form an axisymmetric figure, but the diameter of the horizontal section of the water stirring part 240 is still twice the radius determined above.

[0101] In another specific embodiment, the water stirring rib spirally extends along the side wall surrounding the support column. At this time, the horizontal section of the water stirring part may not form a regular geometric figure, but the radius of the horizontal section of the water stirring part is still the distance from the farthest end of the water stirring rib from the axis to the central axis on this section.

[0102] As Figure 3 shown, in a specific solution of this embodiment, the water stirring member is in an umbrella shape, the support column 210 is equivalent to the handle of the umbrella, and the water stirring disk 230 is equivalent to the umbrella surface. In this water stirring member 200, the radius of the water stirring disk 230 becomes smaller from bottom to top, and the maximum radius section Dmax on the water stirring disk 230 is located at the lowermost end of the water stirring disk 230. Since the water stirring ribs 220 are circumferentially spaced along the support column 210, the uppermost ends of the water stirring ribs 220 are arranged below the water stirring disk 230.

[0103] As Figure 8As shown, in the solution of this embodiment, the middle area of the water stirring disc is recessed downward to form a sealing groove 210-4. The screw enters the sealing groove 210-4 and sequentially passes through the bottom of the sealing groove 210-4 to be fixedly connected to the mounting post. The sealing cover is made of a flexible material and is partially inserted into the screw sealing groove 210-4 to prevent water flow from entering the sealing groove 210-4 to corrode the screw.

[0104] The upper surface of the water stirring disc 230 is a curved surface with the middle area higher than the outer peripheral area. That is to say, the middle area of the upper part of the water stirring disc has a sealing cover 210-5 higher than the upper surface, and the outer peripheral area of the sealing cover is a curved surface extending downward. And a flexible material 260 is covered on the outer peripheral area of the sealing cover.

[0105] In order to further increase the contact area between the water stirring member 200 and the clothes to be washed, raised stirring parts 231 are arranged on the curved surface. In order to further reduce the friction with the clothes, the outer surface of the stirring part is wrapped with a flexible material 260.

[0106] The stirring part has a certain extension length, one end of which is arranged close to the central area of the upper surface of the water stirring disc, and the other end extends towards the edge direction of the water stirring disc.

[0107] More specifically, as Figure 1 shown, the stirring part 231 is in the shape of a rocket. The end where the rocket body is located is arranged close to the central area of the upper surface of the water stirring disc 230, and the end where the rocket head is located extends towards the edge direction of the water stirring disc 230. In this solution, a plurality of stirring parts 231 are arranged at intervals on the upper surface of the water stirring disc 230. Thus, during the washing process of the clothes, the stirring parts 231 can stir the washing water above the water stirring disc 230 as the water stirring member 200 rotates, and can also make the clothes fully rub against the surfaces of the plurality of stirring parts 231 to wash the clothes cleaner.

[0108] In a preferred solution, the uppermost end of the water stirring rib 220 abuts and is fixed to the inner surface of the water stirring disc 230.

[0109] It should be noted that in this solution, the distance from the outermost contour of the water stirring rib 220 to the mounting post is less than the radius of the maximum radius section Dmax of the water stirring disc 230. In the solution of this embodiment, the maximum radius section Dmax can be set at any extension height position of the water stirring disc 230. The water stirring disc 230 can be divided into three parts along the extension direction of the height of the water stirring disc 230, namely the lower area, the middle area and the upper area, and the maximum radius section Dmax can be set in any one of the lower area, the middle area and the upper area. That is to say, along the extension direction of the height of the water stirring disc 230, the radius of the end cover can gradually become smaller, can gradually become larger, or can first gradually become larger and then gradually become smaller.

[0110] For example, the water stirring disk 230 is composed of two parts. One part is a cylindrical structure that abuts against the water stirring ribs 220 and extends upward, and the other part is a conical structure with a gradually decreasing radius at the extending end of the cylindrical structure. In this solution, the maximum radius segment Dmax is still located in the lower region of the water stirring disk 230.

[0111] For example, as Figure 4 shown, the water stirring disk 230 is a disk-shaped structure arranged above the water stirring ribs.

[0112] For example, the water stirring disk 230 is a structure with a radius that first gradually increases and then gradually decreases from bottom to top. In this solution, the maximum radius segment Dmax is located in the middle region of the water stirring disk 230.

[0113] For example, as Figure 6 shown, the water stirring disk 230 is composed of two parts. One part is a frustum-shaped structure that abuts against the water stirring ribs 220 and extends upward, and the other part is a conical structure with a gradually decreasing radius at the extending end of the frustum-shaped structure. In this solution, the maximum radius segment Dmax is still located in the lower region of the water stirring disk 230.

[0114] The water stirring disk can also be in an irregular shape as Figure 5 shown.

[0115] In other solutions of this embodiment, the shape of the water stirring disk 230 can also be a regular or other irregular shape. For example, the cross-section at a certain height position of the water stirring disk 230 can be circular, elliptical, triangular, square, rectangular, a polygon with equal side lengths, a polygon with unequal side lengths, or an irregular shape composed of semi-circles with different radii.

[0116] Of course, since the water stirring disk 230 has a certain thickness, the cross-sectional shape at different thickness positions can also be different.

[0117] In the above solution, the water stirring member is made of plastic, and the flexible material 260 wrapped outside the water stirring member is rubber or silica gel. The water stirring member and the flexible material 260 can be connected together by double injection molding or by secondary plugging. In addition, in order to make the water stirring member more prominent in the washing tub, the flexible material 260 can be colored. In order to make the washing effect better, the flexible material is an antibacterial material.

[0118] For the water stirring member provided in this embodiment, since its outer surface is wrapped with the flexible material 260, the friction with the clothes to be washed is reduced, and the clothes are not easily fuzzed.

[0119] Embodiment 2

[0120] AsFigure 7 As shown in the figure, this embodiment provides a washing tub assembly including the water stirring member of the washing device described in the above embodiment.

[0121] The solution of this embodiment includes: The washing tub assembly includes a washing tub. One end of the support column is cooperatively installed with the bottom of the washing tub, and the other end provided with a water stirring plate extends upward from the bottom of the tub. There is a gap between the maximum radius section and the inner surface of the bottom of the tub, and clothes can be washed within this gap.

[0122] The support column extends upward from the top end of the assembly part coaxially arranged with the bottom of the tub;

[0123] The bottom of the washing tub has a groove-like structure 250 extending downward. The assembly part is arranged in the groove-like structure 250, and its upper end protrudes from the groove-like structure 250 higher than the inner surface of the bottom of the tub or is flush with the inner surface of the bottom of the tub. The radius of the groove-like structure 250 is slightly larger than the radius of the assembly part;

[0124] An installation opening is provided on the bottom surface of the groove-like structure 250, and the stirring shaft passes through the installation opening and is inserted into the assembly part to be connected with the water stirring member;

[0125] The part of the assembly part protruding from the groove-like structure 250 higher than the inner surface of the bottom of the tub is wrapped with a flexible material 260 around its outer circumference.

[0126] The support column includes two parts, namely a connected first extension section and a second extension section;

[0127] Among them, the first extension section is connected to the assembly part and extends upward, and its side wall forms a second guiding surface; the second extension section extends upward from the first extension section, and the radius of the second extension section gradually increases with the increase of height, and its side wall forms a first guiding surface;

[0128] The first guiding surface and the second guiding surface are wrapped with a flexible material 260.

[0129] The first extension section has the same radius as the assembly part, and the two are integrally formed.

[0130] Next, the washing tub assembly will be introduced in detail:

[0131] The washing tub assembly provided in this embodiment includes a water stirring member, and the water stirring member is rotatably arranged in the washing tub. The water stirring member 200 can rotate relative to the washing tub 100, and can also rotate in the same direction or in the opposite direction together with the washing tub 100.

[0132] The washing tub assembly further includes an assembly part coaxially arranged with the bottom of the tub. The water stirring member is connected to the bottom of the tub through the assembly part.

[0133] Specifically, the support column 210 is coaxially arranged with the assembly part 210-1, and the support column 210 extends upward from the top end of the assembly part 210-1. That is to say, the upper end of the assembly part 210-1 is connected to the lower end of the support column 210.

[0134] The water-stirring member 200 is arranged in the washing tub 100 by extending upward along its axis from the bottom of the washing tub 100. The water-stirring disc on the water-stirring member 200 has a maximum radius section Dmax at one of its extending heights. There is a spacing between the maximum radius section Dmax and the inner surface of the bottom of the washing tub 100, and the height value of this spacing is greater than a preset value to prevent dirt and grime from accumulating at this spacing. In this solution, the washing space refers to the space area that the clothes C can reach during the washing process.

[0135] It should be noted that in the embodiments of the present invention, the radius of the water-stirring member 200 refers to the radius of the circle formed with the rotation center as the center at the position with the maximum distance from the rotation center on the cross-section obtained by taking a cross-section of the water-stirring member 200 along the direction perpendicular to its rotation axis.

[0136] More specifically, as Figure 9 shown, in this embodiment, the water-stirring member 200 includes an assembly part 210-1 and a water-stirring part 240 extending upward from the assembly part 210-1. The assembly part 210-1 is arranged as a solid structure, and at least part of the water-stirring part 240 is arranged as a hollow structure. For example, the water-stirring part 240 has a cavity arranged axially from the top end towards the assembly part 210-1.

[0137] 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. 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.

[0138] As a specific implementation manner, the water-stirring member 200 includes a support column 210 and water-stirring ribs 220 arranged on the side wall of the support column 210 and protruding in a direction away from the axis of the support column 210 along the radial direction or close to the radial direction of the support column. The water-stirring ribs 220 extend along the axial direction of the support column in the length direction, and the water-stirring ribs 220 extend in a direction away from the outer circumference of the support column in the width direction. They can be arranged radially or deviate from the radial direction.

[0139] In this embodiment, the assembly part 210-1 is a solid cylinder, preferably a circular cylinder, and the hollow column 210-8 extends upward from the upper end surface of the assembly part 210-1. The outer diameter at the connection of the hollow column 210-8 and the assembly part 210-1 may be greater than the radius of the assembly part 210-1, or may be less than or equal to the radius of the assembly part 210-1; the outer peripheral wall of the hollow column 210-8 and the outer peripheral wall of the assembly part 210-1 extend upward with a smooth transition.

[0140] The water stirring part 240 has a horizontal section with the largest radius at a certain height above the upper end of the assembly part 210-1. A water stirring disc 230 is arranged at the top end of the support column 210. The position with the largest radius Rmax of the water stirring part 240 is formed by the outer periphery of the water stirring disc 230, and the top surface of the water stirring disc 230 is a curved surface protruding upward. A cavity 210-9 similar to the outer shape of the support column 210 is formed inside the hollow column 210-8.

[0141] Preferably, the water stirring ribs 220 are also arranged in a hollow structure.

[0142] More preferably, the internal space of the water stirring ribs 220 communicates with the cavity 210-9 inside the hollow column 210-8.

[0143] More preferably, at least a part of the lower end of the water stirring ribs 220 extends to the outer peripheral wall of the assembly part 210-1 and is integrally formed with the assembly part 210-1, thereby further strengthening the connection strength between the assembly part 210-1 and the water stirring part 240.

[0144] In this embodiment, the water stirring part 240 is connected to a stirring shaft that can rotate through the bottom of the washing tub 100 through the assembly part 210-1, so that the water stirring member 200 can rotate relative to the washing tub 100.

[0145] Specifically, the circumferential positioning between the assembly part 210-1 and the stirring shaft is carried out through a spline, and they rotate together, and the axial positioning is carried out through a screw 210-7.

[0146] In this embodiment, a spline groove coaxial with and extending upward from the bottom end surface of the assembly part 210-1 is arranged on the assembly part 210-1. The spline groove at least partially sleeves the upper end part of the stirring shaft and is key-connected to the stirring shaft. The spline groove is formed on the assembly part 210-1 of the water stirring member 200.

[0147] In this embodiment, an opening communicating with the cavity 210-9 inside the hollow column is provided at the top of the water stirring member 200. The screw 210-7 enters the cavity 210-9 through the opening and is connected downward to the stirring shaft key-connected in the assembly part 210-1, fixedly connecting the water stirring member 200 and the stirring shaft axially. To prevent water from entering the cavity 210-9, a sealing component is installed at the opening.

[0148] Preferably, a sealing groove 210-4 is provided at the top of the water stirring member 200, and the sealing groove 210-4 is coaxially recessed downward from the top surface of the water stirring disk 230. An opening communicating with the cavity 210-9 is provided at the bottom of the sealing groove 210-4.

[0149] Specifically, a through hole, preferably a threaded hole, is provided at the upper end of the assembly part 210-1. The rod part 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 at 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 head screw.

[0150] A sealing cover 210-5 for closing the upper end of the water stirring member 200 is provided at the sealing groove 210-4 to prevent washing water from entering the inside of the water stirring member 200.

[0151] Specifically, the sealing cover 210-5 includes a flat plate part and a plugging part. The flat plate part covers the notch of the sealing groove 210-4 and is embedded in the top of the water stirring member 200, and the plugging part is plugged in the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0152] The top of the flat plate part is in the same plane as the top of the water stirring member 200.

[0153] The sealing groove 210-4 includes a first section and a second section with an increasing diameter from top to bottom. A limiting convex protruding from the outer wall of the lower end of the plugging part in a direction away from the axis of the water stirring member 200 is provided at the lower end of the plugging part, and the limiting convex is engaged at the junction between the first section and the second section.

[0154] Preferably, between the inner walls of the first and second sections of the sealing groove 210-4, there is a tapered surface that slopes downward and away from the axis of the water-stirring member 200 for transitional connection. The shape of the limiting protrusion is adapted to the shape between the first and second sections of the sealing groove 210-4. The outer peripheral surface of the limiting protrusion fits against the inner wall of the second section, and the top of the limiting protrusion fits against the tapered surface between the first and second sections of the limiting groove. Preferably, the bottom of the limiting protrusion is a tapered surface with an outer diameter gradually decreasing from top to bottom, and the outer diameter at the bottom of the limiting protrusion is smaller than the inner diameter at the notch of the sealing groove 210-4.

[0155] In this embodiment, a sealing convex rib extending circumferentially along the plug-in portion is provided in the middle of the plug-in portion. The plug-in portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 through the sealing convex rib. Preferably, the sealing convex rib extends circumferentially along the plug-in portion and is provided with multiple circumferential rows arranged at intervals along the axial direction of the plug-in portion.

[0156] Preferably, in this embodiment, the sealing convex rib slopes upward along the extending direction away from the axis of the water-stirring member 200 to improve the smoothness of inserting the sealing cover 210-5.

[0157] In this solution, no wave wheel disc is provided at the bottom of the washing tub 100, and the laundry to be washed directly contacts the inner surface of the bottom of the washing tub 100.

[0158] In this solution, since no wave wheel disc is provided at the bottom of the washing tub 100 and a spacing is provided between the maximum radius section Dmax and the inner surface of the bottom of the washing tub 100, during the process of washing the laundry, the water flow can scour this gap, thereby preventing dirt accumulation between the water-stirring member 200 and the bottom of the washing tub 100.

[0159] The solution of this embodiment further includes: the preset value is 10 cm. That is to say, the distance between the maximum radius section on the water-stirring member and the inner surface of the bottom of the washing tub is at least 10 cm. Thus, sufficient washing space for the laundry C is ensured.

[0160] More specifically, the washing tub includes a bottom 100-a provided at the lower part and a tub body 100-b provided above the bottom. The maximum radius section of the water-stirring member is provided higher than the highest point of the bottom 100-a. That is to say, the maximum radius section is provided in the tub body 100-b and has a certain distance from the highest position of the bottom 100-a.

[0161] Of course, in order to enable the clothes to be washed within this spacing, the value of this spacing can be adjusted according to the actual situation. That is, in order to divide the washing tub 100 into two washing spaces, the preset value of the spacing can be increased. That is to say, the distance between the maximum radius section Dmax of the water-stirring member 200 and the bottom of the washing tub 100 is increased, so that part of the clothes are washed within this area. As for the preset value and the specific distance between the maximum radius section Dmax of the water-stirring member 200 and the bottom of the washing tub 100 in the finished product, they can be determined according to requirements, and no specific limitation is made in the solution of this embodiment.

[0162] In the specific solution of this embodiment, the radii at the connection between the assembly part 210-1 and the support column 210 are the same, and they are of an integrally formed structure. Of course, in other solutions of this embodiment, the shape of the assembly part 210-1 can be other shapes except for a cylindrical shape, and the solution where its radius is slightly larger than the radius of the support column 210 is also within the protection scope of the present invention.

[0163] When the support column 210 is of a cylindrical structure and the radius of this cylindrical structure is the same along its extending direction. The support column 210 extends upward from the top end of the assembly part 210-1, and a water-stirring disc 230 is provided at the extending end.

[0164] When the support column includes a connected first extending section 211 and a second extending section 212, the first extending section is connected to the assembly part.

[0165] In this solution, a driving device is provided on the washing equipment, and a stirring shaft is installed on the driving device. An installation opening is formed in the bottom of the washing tub 100, and this installation opening is an opening penetrating the bottom of the tub. The stirring shaft of the driving device is inserted into the interior of the assembly part 210-1 through the installation opening to be connected to the water-stirring member 200. When the washing equipment performs a washing operation, the stirring shaft drives the assembly part so that the water-stirring member 200 rotates.

[0166] In a solution of this embodiment, the bottom of the washing tub has a groove-like structure 250 extending downward, and an installation opening is formed in the bottom surface of the groove-like structure 250. The stirring shaft of the driving device is inserted into the assembly part 210-1 vertically arranged in the groove-like structure 250 through the installation opening to be connected to the water-stirring member 200. Among them, the upper end of the assembly part 210-1 is flush with the inner surface of the bottom of the tub. That is to say, in this solution, the lower end of the support column 210 is also flush with the inner surface of the bottom of the tub. Since the water-stirring ribs 220 are arranged on the support column 210 and are connected to one end of the support column 210, the lower ends of the water-stirring ribs 220 are in contact with the inner surface of the bottom of the tub.

[0167] As Figure 7As shown, in another solution of this embodiment, the bottom of the washing tub has a groove-like structure 250 extending downward. The bottom of the washing tub is almost flush with the horizontal plane, and a groove-like structure 250 is formed by downward depression in the middle area of the bottom. An installation opening is provided on the bottom surface of the groove-like structure 250, and the stirring shaft of the driving device is inserted through the installation opening and connected to the water-stirring member 200 by being inserted into the assembly part 210-1 vertically arranged in the groove-like structure 250. Among them, the assembly part 210-1 is vertically arranged and protrudes above the inner surface of the bottom of the groove-like structure 250. The assembly part includes two parts, namely a first part and a second part that are connected to each other. The first part is vertically arranged in the groove-like structure 250 and is connected to the stirring shaft, and the second part protrudes above the inner surface of the bottom of the tub and is connected to the support column 210. In this solution, the radius of the groove-like structure 250 is slightly larger than the radius of the assembly part. More specifically, the radius of the groove-like structure 250 is slightly larger than the radius of the assembly part installed therein, that is, the radius of the first part.

[0168] That is to say, in this solution, there is a certain distance between the upper end of the second part of the assembly part and the inner surface of the bottom of the tub, so there is also a certain distance between the lower end of the water-stirring rib 220 and the inner surface of the bottom of the tub.

[0169] In this solution, a flexible material 260 is covered on the outer periphery of the assembly part. Specifically, the flexible material 260 is wrapped around the part that protrudes above the inner surface of the bottom of the groove-like structure 250, that is, the flexible material 260 is wrapped around the outer periphery of the second part of the assembly part.

[0170] In the solution provided by this embodiment, the lowermost end of the water-stirring rib 220 does not directly contact the bottom of the washing tub, but is arranged at an interval between the assembly part and the inner surface of the bottom of the tub. Thus, during use, when the stirring shaft drives the water-stirring member to rotate, the water-stirring rib 220 will not rub against the inner surface of the bottom of the washing tub, and thus will not increase the frictional force between the water-stirring member and the bottom of the washing tub during rotation.

[0171] Of course, in other solutions of this embodiment, the groove-like structure 250 may not be provided at the bottom of the washing tub, and an installation opening may be directly provided on the surface of the bottom of the tub, and the assembly part directly protrudes above the inner surface of the bottom of the tub. That is to say, there is a certain distance between the lower end of the support rib and the inner surface.

[0172] In the above solution, the lowermost end of the water-stirring rib 220 does not directly contact the bottom of the washing tub 100, but is arranged at an interval from the inner surface of the bottom of the tub. Thus, during use, when the stirring shaft drives the water-stirring member 200 to rotate, the water-stirring rib 220 will not rub against the inner surface of the bottom of the washing tub 100, and thus will not increase the frictional force between the water-stirring member 200 and the bottom of the washing tub 100 during rotation. In addition, it can also avoid the existence of cleaning dead corners between the water-stirring rib 220 and the bottom of the tub.

[0173] The solution of this embodiment further includes: a number of water stirring ribs are arranged at intervals on the outer periphery of the support column, a flexible material 260 is arranged on the outer edge of the water stirring ribs, and the projection perpendicular to the bottom of the barrel at any position on the outer edge is directly located on the inner surface of the bottom of the washing barrel.

[0174] Flexible material 260 is wrapped around the opposite sides of any two adjacent water stirring ribs;

[0175] At any position perpendicular to the support column, the outer edges of a number of water stirring ribs are connected into a circle, and the projection perpendicular to the bottom of the barrel at any position on the circumference of this circle is directly located on the inner surface of the bottom of the washing barrel.

[0176] Taking the perpendicular distance from any position on the outer edge of the water stirring rib 220 to the support column 210 as the radius and the axis of the support column parallel to this outer edge as the center of the circle to draw a circle, the projection perpendicular to the bottom of the barrel at any position on the circumference of this circle is directly located on the inner surface of the bottom of the washing barrel 100.

[0177] The projection perpendicular to the bottom of the barrel at any position on the maximum radius segment Dmax is directly located on the inner surface of the bottom of the washing barrel 100.

[0178] In the solution of this embodiment, the outer edge of the water stirring rib 220 is arc-shaped, a flexible material 260 is arranged on this outer edge, and the projection perpendicular to the bottom of the barrel at any position on this outer edge is directly and unobstructedly located on the inner surface of the bottom of the washing barrel 100. The vertical downward extension from any position on the outer edge of the water stirring rib 220 to the inner bottom of the barrel contacts the inner surface of the inner bottom of the barrel. That is to say, in the position where the projection of the edge where the maximum radius of the water stirring rib 220 is located perpendicular to the bottom of the barrel is located, there is no dial arranged in the straight-line area between the outer periphery of the support column 210.

[0179] Since in this embodiment the water stirring ribs 220 are arranged at intervals along the circumferential direction of the support column 210, at any position perpendicular to the support column, the outer edges of a number of water stirring ribs are connected into a circle, and the projection perpendicular to the bottom of the barrel at any position on the circumference of this circle is directly located on the inner surface of the bottom of the washing barrel 100.

[0180] Since the water stirring rib is a plate-like structure, flexible material 260 is wrapped around the opposite sides of any two adjacent water stirring ribs.

[0181] In the solution of this embodiment, taking the perpendicular distance from the edge where the maximum radius of the water stirring rib 220 is located to the support column 210 as the radius and the center of the support column 210 parallel to the edge where the maximum radius of the water stirring rib 220 is located as the center of the circle to draw a circle, there is no dial arranged in the circular ring area formed between the position where the projection of the circular edge perpendicular to the bottom of the barrel is located and the outer periphery of the support column 210. In this solution, there is no bottom disc-shaped stirring part.

[0182] Similarly, for the circle formed by the edge of the maximum radius segment Dmax on the water stirring plate 230, the position of the projection of the circle edge perpendicular to the bottom of the barrel, there is no dial provided in the annular region formed between it and the outer circumference of the support column 210.

[0183] The solution of this embodiment further includes: the depth of the washing tub 100 is H, and there is a spacing between the maximum radius segment Dmax on the water stirring plate 230 of the water stirring member 200 and the inner surface of the bottom of the tub, and the height of the spacing is h. The above distance h and the depth H of the washing tub 100 satisfy: h / H≥1%. Through a large number of pre-tests, it is found that when the above proportional relationship is satisfied between the distance h and the depth H of the washing tub 100, the effect of preventing dirt from accumulating between the water stirring member 200 and the washing tub 100 is the best.

[0184] Of course, in other solutions of this embodiment, the ratio of the height h of the spacing to the height H of the washing tub 100 can also be greater than or equal to other values.

[0185] In this solution, in order to ensure the washing space for clothes, the maximum radius segment Dmax on the water stirring plate 230 cannot be too large. Specifically, the length of the maximum radius segment Dmax can be set to not exceed the radius length of the inner tub.

[0186] The solution provided by this embodiment, by arranging the water stirring member 200 in the washing tub 100, can not only avoid dirt from accumulating between the water stirring member 200 and the bottom of the tub, improving the user experience, but also save energy consumption.

[0187] The above are only preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to the above-mentioned technical content as equivalent embodiments with equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
