Description

Technical Field

[0001] The present invention belongs to the field of laundry treatment equipment, and more particularly, relates to a washing equipment. Background Art

[0002] As a convenient laundry 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, and 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 wash the clothes to be cleaned in the inner tub. The existing pulsator is usually a flat circular pulsator. During washing, dirt, lint and other impurities on the clothes are likely to accumulate in the gap between the bottom surface of the pulsator and the inner tub, and cannot be effectively cleaned simply by flushing. Moreover, most of the clothes cover the pulsator during washing, which is likely to cause clothes entanglement and wear, and at the same time increases the energy consumption of the motor. And, dirt and lint are prone to breed bacteria in a humid environment for a long time, bringing a bad user experience. If you want to thoroughly clean, you need to remove the pulsator and brush the dirt in the gap, which is a relatively complicated operation and further deteriorates the user experience.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0062] Embodiment 1

[0063] As Figures 1 to 3 shown, this embodiment provides a washing device.

[0064] The washing device includes an outer tub, and a washing tub coaxially disposed in the outer tub. There are cleaning particles for cleaning the tub wall between the outer tub and the washing tub.

[0065] The interior of the washing tub has a rotatable water-stirring member that extends upward from the bottom of the washing tub, and no dial is provided inside the washing tub.

[0066] The washing device provided in this embodiment is a washing machine with a self-cleaning function. The washing machine includes an outer tub 100-1, and a washing tub 100 coaxially disposed in the outer tub 100-1. There are cleaning particles 270 for cleaning the tub wall between the outer tub 100-1 and the washing tub 100, thus preventing stains from adhering between the outer tub 100-1 and the washing tub 100.

[0067] In addition, a water-stirring member is provided inside the washing tub, but no dial is provided. The water-stirring member extends upward from the bottom of the washing tub. Among them, 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.

[0068] The solution provided by the present invention provides cleaning particles 270 between the outer tub 100-1 and the washing tub to keep them clean. Moreover, no dial is provided inside the washing device, thus avoiding dirt and grime accumulation between the water-stirring member and the bottom of the washing tub. This solution can prevent residual stains or bacteria in the washing device from causing secondary pollution to the clothes to be washed, improving the user experience.

[0069] The solution of this embodiment further includes: the water stirring member has a maximum radius section at a certain extension height, there is a distance between the maximum radius section and the inner surface of the bottom of the barrel, and the clothes can be washed below the position where the maximum radius section of the water stirring member is located.

[0070] The water stirring member 200 is arranged in the washing barrel 100 by extending upward along its axis from the bottom of the washing barrel 100. The water stirring member 200 has a maximum radius section Dmax at one of its extension heights. There is a distance between the maximum radius section Dmax and the inner surface of the bottom of the washing barrel 100, and the height value of this distance is greater than a preset value, so that the clothes to be washed can be washed within this distance, avoiding dirt accumulation at this distance. In this solution, the washing space refers to the space area that the clothes C can reach during the washing process.

[0071] It should be noted that in the embodiment 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 where the distance from the rotation center is the largest on the cross-section obtained by taking a cross-section of the water stirring member 200 along the direction perpendicular to its rotation axis.

[0072] Next, the specific structure of the water stirring member in the washing barrel will be introduced in detail:

[0073] The water stirring member provided in this embodiment is rotatably arranged in the washing barrel of the washing machine to drive the washing water to rotate and realize the washing of the clothes in the washing barrel.

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

[0075] In the solution of this embodiment, a flexible material 260 is wrapped on the outer surface of the water stirring member. The flexible material 260 is wrapped only on the support column, or only on the water stirring disk, or on both the support column and the water stirring disk.

[0076] For the water stirring member provided in this embodiment, 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.

[0077] Since one end of the water-stirring disk is set at any height of the support column, the other end extends above the washing tub, and the maximum radius segment can be at a certain extended position. That is to say, the water-stirring disk has a certain thickness, and the maximum radius segment is at this arbitrary thickness. The shape of the water-stirring disk can be a candied gourd-like structure or an umbrella surface-like structure. Of course, it can also be other shapes, and the specific shape is not limited in the solution of this embodiment. As long as it can stir the water flow to rotate.

[0078] The water-stirring member includes a support column 210 coaxially arranged with the bottom of the tub, water-stirring ribs 220 arranged on the outer periphery of the support column 210, and a water-stirring disk 230 arranged at the end of the support column 210. That is to say, one end of the support column 210 is connected and cooperated with the bottom of the tub, and the other end extends towards the tub opening, and the water-stirring disk 230 is arranged at its extended end. The water-stirring ribs 220 extend obliquely upward from the outer periphery of the support column 210 away from the water-stirring disk towards the washing tub 100.

[0079] 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.

[0080] In another specific solution of this embodiment, the support column 210 includes two parts, namely a connected first extension segment 211 and a second extension segment 212. Among them, the first extension segment 211 extends upward from the bottom of the washing tub 100, and its side wall forms a second guiding surface 214. The second extension segment 212 extends upward from the first extension segment 211, and the radius of the second extension segment 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 segment 211 and the second extension segment 212 are not the same. The radius of the first extension segment 211 remains unchanged, and the radius of the second extension segment 212 gradually becomes larger with the increase of height. By setting the first extension segment 211 and the second extension segment 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 disk 230 is greatly increased, and thus 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 disk 230 is effectively reduced. And in this solution, the contact area between the end cover and the support column 210 is increased, making the fixation between the two more firm.

[0081] It should be noted that in the embodiment of the present invention, the maximum radius segment refers to the radius of the horizontal cross-section of the water-stirring part 240. The water-stirring part 240 takes a cross-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 cross-section.

[0082] Specifically, if the horizontal cross-section of the water-stirring part 240 is Figure 11For the circular shape shown, the radius mentioned is the radius R1 of the circular cross-section. If the horizontal cross-section of the water-stirring part 240 is Figures 12 to 17 a non-circular shape as shown, the radius mentioned is the distance R2 from the point on the cross-section farthest from the rotation center to the rotation center (i.e., the position marked by "×" in the figure).

[0083] In the above solution, a flexible material 260 is wrapped around the outer periphery of the support column, thereby further reducing the friction with the clothes.

[0084] The water-stirring rib 220 in this embodiment 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.

[0085] 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 rib 220 is arc-shaped. And a flexible material 260 is wrapped around the outer contour, thereby further reducing the friction with the clothes.

[0086] More particularly, the water-stirring rib 220 in this solution 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.

[0087] 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 first increase gradually and then decrease, or the radius can change within a smaller range at first and then within a larger range.

[0088] 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 periphery of the water-stirring disc 230. In this solution, the number of water-stirring ribs can be set according to requirements.

[0089] Specifically, as Figure 3 shown, in this embodiment, the water stirring member 200 includes an assembling part 210-1 and a water stirring part 240 extending upward from the assembling part 210-1. The assembling 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 is provided with a cavity extending axially from the top end towards the assembling part 210-1.

[0090] Specifically, in this embodiment, the assembling part 210-1 is a solid cylinder, 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 assembling part 210-1, and the assembling part 210-1 can also seal the lower end of the hollow structure of the water stirring part 240.

[0091] 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 periphery of the support column in the width direction, and can be arranged along the radial direction or deviate from the radial direction.

[0092] In this embodiment, the assembling part 210-1 is a solid cylinder, preferably a cylinder, and the hollow column 210-8 extends upward from the upper end surface of the assembling part 210-1. The outer diameter of the connection part between the hollow column 210-8 and the assembling part 210-1 can be greater than the radius of the assembling part 210-1, or less than or equal to the radius of the assembling part 210-1; the outer peripheral wall of the hollow column 210-8 and the outer peripheral wall of the assembling part 210-1 extend smoothly upward.

[0093] The water stirring part 240 has a horizontal section with the largest radius at a certain height from the upper end of the assembling part 210-1. A water stirring disc 230 is arranged at the top end of the support column 210. The maximum 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 external shape of the support column 210 is formed inside the hollow column 210-8.

[0094] Preferably, the water stirring ribs 220 are also arranged as hollow structures.

[0095] More preferably, the internal space of the water stirring ribs 220 is communicated with the cavity 210-9 inside the hollow column 210-8.

[0096] Further preferably, at least a part of the lower end of the water stirring rib 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.

[0097] In this embodiment, the water stirring part 240 is connected to the stirring shaft that can rotatably pass through the bottom of the washing tub 100 through the assembly part 210-1, so that the water stirring member 200 can rotate relative to the washing tub 100.

[0098] Specifically, the assembly part 210-1 and the stirring shaft are circumferentially positioned by splines and rotate together, and are axially positioned by screws 210-7.

[0099] In this embodiment, a spline groove that extends coaxially upward from the bottom end face of the assembly part 210-1 is provided 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.

[0100] 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 inside 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.

[0101] Preferably, a sealing groove 210-4 is provided at the top of the water stirring member 200. The sealing groove 210-4 is recessed coaxially downward from the top surface of the water stirring disc 230. An opening communicating with the cavity 210-9 is provided at the bottom of the sealing groove 210-4.

[0102] Specifically, a through hole, preferably a threaded hole, is provided at the upper end part 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. 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.

[0103] 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.

[0104] Specifically, the sealing cover 210-5 includes a flat plate portion and a plugging 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 plugging portion is plugged into the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0105] The top of the flat plate portion is in the same plane as the top of the water stirring member 200.

[0106] The sealing groove 210-4 includes a first section and a second section with an increasing diameter from top to bottom. The lower end of the plugging portion is provided with a limiting convex protruding from the outer wall of the lower end of the plugging portion in a direction away from the axis of the water stirring member 200. The limiting convex is engaged at the junction between the first section and the second section.

[0107] Preferably, the inner wall of the first section and the inner wall of the second section of the sealing groove 210-4 are connected by a tapered surface that slopes downward and away from the axis of the water stirring member 200. The shape of the limiting convex 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 convex fits with the inner wall of the second section, and the top of the limiting convex fits with the tapered surface between the first section and the second section of the limiting groove. Preferably, the bottom of the limiting convex is provided with a tapered surface with a gradually decreasing outer diameter from top to bottom, and the outer diameter of the bottom of the limiting convex is smaller than the inner diameter at the notch of the sealing groove 210-4.

[0108] In this embodiment, a sealing convex rib extending along the circumferential direction of the plugging portion is provided in the middle of the plugging portion. The plugging 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 along the circumferential direction of the plugging portion and is provided with multiple circles arranged at intervals along the axial direction of the plugging portion.

[0109] 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.

[0110] In this solution, the upper surface of the water stirring rib abuts against the inner surface of the water stirring disc, and the area where the two abut is wrapped with a flexible material 260. Also, since the water stirring rib is a plate-like structure, its outer edge and both side surfaces of the water stirring rib are wrapped with the flexible material 260. That is to say, in this solution, the areas where the water stirring rib contacts the clothes are all wrapped with the flexible material 260. Thus, the friction between it and the clothes is further reduced.

[0111] Due to the above structure of the water stirring rib 220, 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 close to 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 close to 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.

[0112] It can be understood that the clothes moving from the bottom of the tub towards the central area can also be lifted along the outer peripheral edge of the water stirring rib 220 after contacting the water stirring rib 220. After moving to the 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.

[0113] In the above structure, the radius of any horizontal section of the water stirring part 240 specifically refers to the distance from the farthest point from the axis on the water stirring rib 220 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 points from the axis of the two opposite water stirring ribs 220 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 oppositely arranged 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.

[0114] In another specific embodiment, the water stirring rib spirally extends along the side wall around 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 point from the axis on the water stirring rib to the central axis on this section.

[0115] In this embodiment, the water stirring disk 230 has an extension height in the central axis direction of the washing tub 100, and the maximum radius section Dmax is located on the water stirring disk 230.

[0116] As Figures 4 - 5 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 umbrella handle of the umbrella, and the water stirring disk 230 is equivalent to the umbrella surface of the umbrella. 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 arranged at intervals along the circumferential direction of the support column 210, the uppermost ends of the water stirring ribs 220 are arranged below the water stirring disk 230.

[0117] The upper surface of the water-stirring plate 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 plate has a sealing cover 210-5 higher than the upper surface, and the outer peripheral area of the sealing cover 210-5 is a curved surface extending downward. And a flexible material 260 is covered on the outer peripheral area of the sealing cover 210-5.

[0118] 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 parts is wrapped with a flexible material 260.

[0119] The stirring parts have a certain extension length, one end of which is arranged close to the central area of the upper surface of the water-stirring plate, and the other end extends towards the edge direction of the water-stirring plate.

[0120] More specifically, as Figure 4 shown, the stirring part 231 is in the shape of a rocket, one end where the rocket body is located is arranged close to the central area of the upper surface of the water-stirring plate 230, and the end where the rocket head is located extends towards the edge direction of the water-stirring plate 230. In this solution, a plurality of stirring parts 231 are arranged at intervals on the upper surface of the water-stirring plate 230. Thus, during the washing process of the clothes, the stirring parts 231 can stir the washing water above the water-stirring plate 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, washing the clothes cleaner.

[0121] In a preferred solution, the uppermost end of the water-stirring rib 220 is in contact and fixed with the inner surface of the water-stirring plate 230.

[0122] 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 plate 230. That is to say, the radius of the maximum radius section Dmax on the water-stirring plate 230 is greater than or equal to the radius of the circle formed by the outer periphery of the water-stirring rib 220.

[0123] In the solution of this embodiment, the maximum radius section Dmax can be set at any extension height position of the water-stirring plate 230. The water-stirring plate 230 can be divided into three parts along the extension direction of the height of the water-stirring plate 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 plate 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.

[0124] 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.

[0125] For example, as Figure 7 shown, the water stirring disk 230 is a disk-shaped structure disposed above the water stirring ribs.

[0126] 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.

[0127] For example, as Figure 9 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.

[0128] The water stirring disk can also be in the Figure 8 irregular shape shown.

[0129] 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.

[0130] Of course, since the water stirring disk 230 has a certain thickness, the cross-sectional shapes at different thickness positions can also be different.

[0131] 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. Additionally, in order to make the water stirring member more prominent in the washing tub, the flexible material 260 can be colored.

[0132] The water stirring member provided in this embodiment reduces the friction with the clothes to be washed due to the flexible material 260 wrapped around its outer surface, making the clothes less likely to pill.

[0133] In the solution of this embodiment, both the washing tub and the outer tub 100-1 of the washing machine are designed to be approximately parallel to the horizontal plane, and the gap between them is larger than the radius of the cleaning particles 270, so that the cleaning particles 270 can smoothly move in the gap along with the movement of the water flow to clean the tub wall.

[0134] The washing machine further includes an assembly part coaxially arranged with the bottom of the washing tub, and the water stirring member is connected to the bottom of the tub through the assembly part.

[0135] 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.

[0136] 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 extended 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. In the solution of the present invention, since the height value of this spacing is set to be greater than the preset value, the power of the water flow will not become very small when it moves into the spacing, and it can also wash the stains at this spacing, thus avoiding dirt accumulation at this spacing. In addition, since there is a spacing between the maximum radius section Dmax and the inner surface of the washing tub 100, the clothes to be washed can be washed within this spacing.

[0137] It should be noted that in the embodiment 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 largest 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.

[0138] In this solution, a wave wheel disc is not provided at the bottom of the washing tub 100, and the clothes to be washed are directly in contact with the inner surface of the bottom of the washing tub 100.

[0139] In this solution, since a wave wheel disc is not 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 clothes, the water flow can wash this gap, thus avoiding dirt accumulation between the water stirring member 200 and the bottom of the washing tub 100.

[0140] The solution of this embodiment further includes: 10 cm. That is to say, the minimum distance between the maximum radius section on the water stirring member and the inner surface of the bottom of the washing tub is 10 cm. Thus, sufficient washing space is guaranteed for the clothes C.

[0141] More specifically, the washing tub includes a tub bottom 100-a provided at the lower part and a tub body 100-b provided above the tub bottom, and the maximum radius section of the water stirring member is provided higher than the highest point of the tub 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 tub bottom 100-a.

[0142] Of course, in order to enable the clothes to be washed within this distance, the value of this distance 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 distance can be increased. That is to say, the distance between the maximum radius section Dmax of the water stirring member 200 and the tub bottom of the washing tub 100 is increased, so that some clothes are washed in 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 tub 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.

[0143] In the specific solution of this embodiment, the radius at the connection between the assembly part 210-1 and the support column 210 is the same, and the two 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.

[0144] When the support column 210 is of a cylindrical structure and the radius of the 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.

[0145] When the support column includes a connected first extension section 211 and a second extension section 212, the first extension section is connected to the assembly part.

[0146] In this solution, the washing device includes a flange provided outside the tub bottom of the washing tub, and also includes a driving device provided outside the outer tub 100-1. A stirring shaft is installed on the driving device. An installation opening is provided on the tub bottom of the washing tub 100, and the installation opening is an opening penetrating the tub bottom. The stirring shaft of the driving device is inserted into the interior of the assembly part 210-1 through the flange and the installation opening to be connected to the water stirring member 200. When the washing device performs a washing operation, the stirring shaft drives the assembly part to rotate the water stirring member 200.

[0147] In a 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. A groove-like structure 250 is formed by downward depression in the middle area of the bottom of the tub. An installation opening is provided on the bottom surface of the groove-like structure 250. The stirring shaft of the driving device is connected to the water-stirring member 200 by passing through the installation opening and inserting into the assembly part 210-1 vertically arranged in the groove-like structure 250. 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 connected to one end of the support column 210, the lower end of the water-stirring ribs 220 abuts against the inner surface of the bottom of the tub.

[0148] As Figure 7 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. A groove-like structure 250 is formed by downward depression in the middle area of the bottom of the tub. An installation opening is provided on the bottom surface of the groove-like structure 250. The stirring shaft of the driving device is connected to the water-stirring member 200 by passing through the installation opening and inserting 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 tub higher than 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. Among them, the first part is vertically arranged in the groove-like structure 250 and 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.

[0149] 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 ribs 220 and the inner surface of the bottom of the tub.

[0150] 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 groove-like structure 250 higher than the inner surface of the bottom of the tub, that is, the flexible material 260 is wrapped around the outer periphery of the second part of the assembly part.

[0151] In the solution provided by this embodiment, the lowermost end of the water-stirring ribs 220 does not directly contact the bottom of the washing tub, but is spaced 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 ribs 220 will not rub the inner surface of the bottom of the washing tub, so that the friction force between the water-stirring member and the bottom of the washing tub during rotation will not increase.

[0152] In the solution of this embodiment, since there is a groove-like structure in the middle area of the washing tub, a number of water passing holes are provided in the area between the outer periphery of the groove-like structure and the peripheral wall of the washing tub, so that the water in the washing tub can enter the outer tub 100-1. Among them, the inner diameter of the water passing holes is smaller than the radius of the cleaning particles 270, so as to prevent the cleaning particles 270 from entering the washing tub from between the washing tub and the outer tub 100-1.

[0153] 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 opened on the surface of the bottom of the tub, and the assembly part directly protrudes from 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.

[0154] 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 spaced 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 the inner surface of the bottom of the washing tub 100, so that the friction force between the water stirring member 200 and the bottom of the washing tub 100 during rotation will not be increased. In addition, it can also prevent there from being a cleaning dead angle between the water stirring rib 220 and the bottom of the tub.

[0155] The solution of this embodiment further includes: a receiving cavity 280 for collecting cleaning particles 270 is provided at the lower part of the washing device and is connected to the outer tub 100-1;

[0156] When draining water, the cleaning particles 270 enter the receiving cavity 280 from between the outer tub 100-1 and the washing tub; when filling water, the cleaning particles 270 enter between the outer tub 100-1 and the washing tub from the receiving cavity 280.

[0157] The receiving cavity 280 is communicated with the drain pipe 300, and a filtering device 290 for blocking the cleaning particles 270 is provided therebetween.

[0158] The washing device includes a drain valve 310 provided above the drain pipe 300, and the drain valve 310 closes or opens the drain pipe 300 by abutting against or away from the wall of the receiving cavity 280 on the side where the filtering device 290 is located.

[0159] A receiving cavity 280 for collecting cleaning particles 270 is provided below the bottom wall of the outer tub 100-1 of the washing machine, and the receiving cavity 280 is communicated with the outer tub 100-1 through an opening provided on the bottom wall. In addition, the receiving cavity 280 is also communicated with the drain pipe 300, and a filtering device 290 for blocking the cleaning particles 270 is provided between the drain pipe 300 and the receiving cavity 280.

[0160] Specifically, the filtering device 290 is a filter screen, which is arranged on the right side of the accommodation cavity 280. A drain valve 310 is installed on the right side of the filter screen. A valve plug is arranged on the drain valve 310, and the water inlet of the drain pipe 300 is located below the valve plug. When the washing machine executes the washing program, the valve plug of the drain valve 310 moves to the position of the accommodation cavity 280 to block the water inlet of the drain pipe 300, and the washing bucket inlet cleaning particles 270 enter between the outer tub 100-1 and the washing bucket from the accommodation cavity 280. When the washing is over, the valve plug of the drain valve 310 moves to a position away from the accommodation cavity 280 to open the water inlet of the drain pipe 300, and the cleaning particles 270 enter the accommodation cavity 280 with the water flow for storage between the outer tub 100-1 and the washing bucket.

[0161] It should be noted that in this solution, there is no bottom disk-shaped stirring part.

[0162] In the solution of this embodiment, the outer edge of the water stirring rib 220 is arc-shaped, and a flexible material 260 is arranged on this outer edge. Since there is no dial plate in the washing bucket, the projection of any position of this outer edge vertically towards the bottom of the bucket is directly and unobstructedly located on the inner surface of the bottom of the washing bucket 100. Any position of the outer edge of the water stirring rib 220 vertically extends down to the inner bottom of the barrel and contacts the inner surface of the inner bottom of the barrel.

[0163] Since the water stirring ribs 220 in this embodiment are arranged at intervals along the circumferential direction of the support column 210, the outer edges of several water stirring ribs at any position perpendicular to the support column are connected into a circle, and the projection of any position on the circumference of this circle vertically towards the bottom of the bucket is directly located on the inner surface of the bottom of the washing bucket 100.

[0164] Since the water stirring rib is a plate-like structure, the opposite side surfaces of any two adjacent water stirring ribs are wrapped with the flexible material 260.

[0165] In the solution of this embodiment, a circle is drawn with the vertical 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. The position where the projection of the edge of this circle vertically towards the bottom of the bucket is located forms an annular area with no dial plate between the outer circumference of the support column 210.

[0166] Similarly, for the circle formed by the edge of the maximum radius segment Dmax on the water stirring disk 230, the position where the projection of the edge of this circle vertically towards the bottom of the bucket is located forms an annular area with no dial plate between the outer circumference of the support column 210.

[0167] 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 section Dmax on the water stirring disc 230 of the water stirring member 200 and the inner surface of the tub bottom, 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 and scale from accumulating between the water stirring member 200 and the washing tub 100 is the best.

[0168] 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.

[0169] In this solution, in order to ensure the washing space for clothes, the maximum radius section Dmax on the water stirring disc 230 cannot be too large. Specifically, the length of the maximum radius section Dmax can be set to not exceed the radius length of the inner tub.

[0170] The solution provided by this embodiment not only sets cleaning particles 270 between the outer tub 100-1 and the washing tub to keep them clean. Moreover, no dial is provided inside the washing to avoid dirt and scale from accumulating between the water stirring member and the washing tub floor. This solution can avoid secondary pollution of the clothes to be washed caused by residual stains or bacteria in the washing equipment, and improves the user experience.

[0171] The above are only the 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 the 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 using the technical content prompted above into equivalent embodiments of equivalent changes. However, 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's solution.
