Description

A washing device Technical Field

[0001] The present invention belongs to the field of clothing processing equipment, and in particular, relates to a washing equipment. Background Art

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

[0003] A pulsator washing machine usually includes a washing tub and a pulsator, with the pulsator being located at the bottom of the washing tub. When the pulsator washing machine is working, the rotation of the pulsator drives the washing water in the tub to rotate, thereby washing the clothes to be washed in the tub. Existing pulsators are usually flat, circular pulsators. During washing, impurities such as dirt and lint on the clothes are easily accumulated in the gap between the bottom surface of the pulsator and the tub. They cannot be effectively cleaned by simply flushing. In addition, most of the clothes are covered on the pulsator during washing, which easily causes the clothes to become entangled and worn, while also increasing the energy consumption of the motor. In addition, dirt and lint are easily bred by bacteria when they are in a humid environment for a long time, which brings a bad user experience. If you want to clean it thoroughly, you need to remove the pulsator and scrub the dirt in the gap. This operation is relatively complicated, which further deteriorates the user experience.

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

[0005] Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing device in which no dial is provided in the washing tub, thereby avoiding accumulation of stains between the water stirring member and the bottom of the washing tub.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is to provide a washing device.

[0008] The washing device comprises an outer barrel, and a washing barrel coaxially arranged in the outer barrel, and cleaning particles for cleaning the barrel wall are arranged between the outer barrel and the washing barrel;

[0009] A rotatable water stirring member is provided inside the washing tub, and the water stirring member extends upward from the bottom of the washing tub. No dial is provided inside the washing tub.

[0010] The solution provided by the present invention not only places cleaning particles between the outer tub and the washing tub, keeping them clean, but also eliminates the need for a dial inside the washing machine, thereby preventing dirt and grime from accumulating between the water-stirring member and the washing tub floor. This solution prevents residual stains or bacteria in the washing machine from causing secondary contamination of the laundry, thereby improving the user experience.

[0011] Furthermore, the water stirring member has a maximum radius section at a certain extension height, and there is a distance between the maximum radius section and the inner surface of the barrel bottom, so that clothes can be washed below the position of the maximum radius section of the water stirring member.

[0012] Furthermore, the water stirring member includes a mounting portion coaxially arranged with the bottom of the barrel and a water stirring portion arranged above the mounting portion;

[0013] The inner surface of the bottom of the washing tub has a groove-like structure extending downward, the assembly portion is arranged in the groove-like structure, the upper end of the assembly portion protrudes from the groove-like structure and is higher than the inner surface of the bottom of the tub or is arranged flush with the inner surface of the bottom of the tub, and the radius of the groove-like structure is slightly larger than the radius of the assembly portion;

[0014] The bottom surface of the groove structure is provided with an installation opening, and the stirring shaft passes through the installation opening and is inserted into the assembly portion to be connected with the water stirring portion;

[0019] The support column extends upward from the top of the assembly portion, and the radius of the connection between the support column and the assembly portion is similar.

[0020] Furthermore, the bottom of the washing tub and the bottom of the outer tub are both parallel to the horizontal plane, and the gap between them is larger than the radius of the cleaning particles;

[0021] The stirring shaft passes through the bottom of the outer barrel, the mounting opening and the flange in sequence and is inserted into the assembly part to connect with the water stirring part;

[0022] The water stirring part further comprises a water stirring disk with an umbrella structure, which is installed above the water stirring rib and at the extended end position of the water stirring member, and the maximum radius section is located on the water stirring disk.

[0023] Furthermore, the middle area of ​​the upper part of the water stirring plate has a sealing cover higher than the upper surface, and the peripheral area of ​​the sealing cover is a curved surface extending downward;

[0024] A plurality of raised stirring parts are arranged on the curved surface. The stirring parts have a certain extension length. One end of the stirring part is arranged near the central area of ​​the upper surface of the water stirring plate, and the other end is extended toward the edge of the water stirring plate.

[0027] Furthermore, the accommodating chamber is communicated with the drain pipe, and a filtering device for blocking cleaning particles is provided between the two.

[0028] Furthermore, the washing device includes a drain valve arranged above the drain pipe, and the drain valve closes or opens the drain pipe by abutting against or moving away from the accommodating cavity wall on the side where the filtering device is located.

[0029] Furthermore, the outer surface of the water-stirring member is at least partially wrapped with a flexible material.

[0030] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0031] 1. The solution provided by the present invention not only places cleaning particles between the outer tub and the washing tub, keeping them clean, but also eliminates the need for a dial inside the washing machine, thereby preventing dirt and grime from accumulating between the water-stirring components and the washing tub floor. This solution prevents residual stains or bacteria from contaminating the laundry, improving the user experience.

[0032] 2. In the solution provided by the present invention, since the outer surface of the water-stirring member is at least partially wrapped with a flexible material, the friction between the water-stirring member and the clothes is reduced, making the clothes less likely to become linted.

[0033] 3. The solution provided by the present invention further increases the contact area with the clothes due to the provision of a plurality of raised stirring parts on the upper surface of the water stirring tray, so that the clothes are washed more cleanly.

[0034] 4. The solution provided by the present invention can prevent cleaning particles from entering the drain pipe and being discharged because a filtering device is provided between the accommodating chamber and the drain pipe.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0058] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0059] As shown in FIG. 1 to FIG. 16 , the present invention provides a washing device.

[0060] The washing device comprises an outer barrel, and a washing barrel coaxially arranged in the outer barrel, and cleaning particles for cleaning the barrel wall are arranged between the outer barrel and the washing barrel;

[0061] A rotatable water stirring member is provided inside the washing tub, and the water stirring member extends upward from the bottom of the washing tub. No dial is provided inside the washing tub.

[0062] The solution provided by the present invention does not have a dial inside the washing machine, thereby preventing dirt and grime from accumulating between the water stirring member and the washing tub floor. This solution can prevent residual stains or bacteria in the washing machine from causing secondary contamination of the laundry, thereby improving the user experience.

[0063] Example 1

[0064] As shown in FIG. 1 to FIG. 3 , this embodiment provides a washing device.

[0065] The washing device comprises an outer barrel, and a washing barrel coaxially arranged in the outer barrel, and cleaning particles for cleaning the barrel wall are arranged between the outer barrel and the washing barrel;

[0066] A rotatable water stirring member is provided inside the washing tub, and the water stirring member extends upward from the bottom of the washing tub. No dial is provided inside the washing tub.

[0067] This embodiment provides a washing machine with a self-cleaning function. The washing machine includes an outer tub 100-1 and a wash tub 100 coaxially disposed within the outer tub 100-1. Cleaning particles 270 are disposed between the outer tub 100-1 and the wash tub 100 to clean the tub wall, thereby preventing dirt from accumulating between the outer tub 100-1 and the wash tub 100.

[0068] 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. The water stirring member 200 can rotate relative to the washing tub 100, and can also rotate together with the washing tub 100 in the same direction or in the opposite direction.

[0069] The present invention provides a solution that incorporates cleaning particles 270 between the outer tub 100-1 and the washing tub, maintaining a clean space between them. Furthermore, no dial is provided inside the washing tub, preventing dirt from accumulating between the agitator and the floor of the washing tub. This solution prevents residual stains or bacteria from contaminating the laundry, improving the user experience.

[0070] The solution of this embodiment also includes: the water stirring member has a maximum radius section at a certain extension height, and there is a distance between the maximum radius section and the inner surface of the barrel bottom, so that clothes can be washed below the position of the maximum radius section of the water stirring member.

[0071] The water-stirring member 200 extends axially upward from the bottom of the washing tub 100 and is disposed within the washing tub 100. The water-stirring member 200 has a maximum radius section Dmax at one portion of its extension. A distance exists between this maximum radius section Dmax and the inner surface of the bottom of the washing tub 100, and this distance is greater than a predetermined value. This allows the laundry to be washed within this distance, preventing dirt from accumulating there. In this embodiment, the washing space refers to the spatial area accessible to the laundry C during the washing process.

[0072] 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 a circle formed by taking a cross section of the water-stirring member 200 in a direction perpendicular to its rotation axis and taking the rotation center as the center at the maximum distance from the rotation center on the cross section.

[0073] Next, we will introduce the specific structure of the water stirring component in the washing tub in detail:

[0074] The water stirring member provided in this embodiment is rotatably arranged in the washing tub of the washing machine to drive the washing water to rotate and wash the clothes in the washing tub.

[0075] The water stirring member includes a support column and a water stirring tray. The support column has a certain extension length, one end of which engages with the bottom of the washing tub and the other end extends toward the tub opening. One end of the water stirring tray is positioned at any height relative to the support column, and the other end extends upward from the washing tub. The water stirring tray has a maximum radius section, which can be located at any extension height of the water stirring tray.

[0076] In the solution of this embodiment, the outer surface of the water stirring member is wrapped with a flexible material 260. The flexible material 260 can be wrapped only on the support column, only on the water stirring plate, or both on the support column and the water stirring plate.

[0077] The water-stirring member provided in this embodiment has its outer surface wrapped with the flexible material 260 , thereby reducing the friction between the water-stirring member and the clothes, making the clothes less likely to become linted.

[0078] One end of the water stirring tray is positioned at any height on the support column, while the other end extends upward from the washing tub, with the maximum radius section located at a specific extension position. This means the water stirring tray has a certain thickness, with the maximum radius section located at that arbitrary thickness. The shape of the water stirring tray can be a candied haws or umbrella-shaped. Of course, other shapes are possible, and this embodiment does not limit the specific shape. Any shape is sufficient as long as it can stir the water flow and cause it to rotate.

[0079] The water stirring member includes a support column 210 coaxially arranged with the bottom of the washing tub, a water stirring rib 220 disposed on the outer periphery of the support column 210, and a water stirring tray 230 disposed at the end of the support column 210. Specifically, one end of the support column 210 is matingly connected to the bottom of the washing tub, while the other end extends toward the opening of the washing tub, with the water stirring tray 230 disposed at the end of the extension. The water stirring rib 220 extends obliquely from the outer periphery of the end of the support column 210 away from the water stirring tray toward the top of the washing tub 100.

[0080] In a specific solution of this embodiment, the support column 210 is a cylindrical structure, and the radius of the cylindrical structure is the same along its extension direction.

[0081] In another specific embodiment of this embodiment, the support column 210 includes two parts: a first extension section 211 and a second extension section 212. The first extension section 211 extends upward from the bottom of the washing tub 100, with its sidewall forming a second guide surface 214. The second extension section 212 extends upward from the first extension section 211, and its radius gradually increases with increasing height. Its sidewall forms a first guide surface 213. In other words, the radii of the first extension section 211 and the second extension section 212 are different. The radius of the first extension section 211 remains constant, while the radius of the second extension section 212 gradually increases with increasing height. By providing the first extension section 211 and the second extension section 212, the angle between the sidewall of the upper end of the support column 210 and the lower surface of the water stirring tray 230 is significantly increased, thereby effectively reducing the problem of cleaning dead corners between the upper end of the support column 210 and the lower surface of the water stirring tray 230, where clothes cannot reach. Furthermore, in this solution, the contact area between the end cover and the support column 210 is increased, so that the two are fixed more firmly.

[0082] It should be noted that, in the embodiment of the present invention, the maximum radius section refers to the radius of the horizontal cross section of the water stirring portion 240, and the water stirring portion 240 is cross-sectioned in the horizontal direction (see FIG10), and the distance from the farthest point from the center of rotation on the obtained horizontal cross section to the center of rotation.

[0083] Specifically, if the horizontal cross-section of the agitating portion 240 is circular as shown in Figure 11, the radius is the radius R1 of the circular cross-section. If the horizontal cross-section of the agitating portion 240 is non-circular as shown in Figures 12 to 17, the radius is the distance R2 from the farthest point on the cross-section from the center of rotation to the center of rotation (i.e., the position marked with "×" in the figures).

[0084] In the above solution, the outer periphery of the support column is wrapped with a flexible material 260, thereby further reducing the friction with the clothes.

[0085] The water stirring rib 220 in this embodiment is a plate-like structure with one end provided 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 .

[0086] It is worth noting that the extension length of the water-stirring rib 220 varies at different heights of the support column 210. In other words, the outer contour of the water-stirring rib 220 is arc-shaped. Furthermore, the outer contour is wrapped with a flexible material 260, thereby further reducing friction with clothing.

[0087] It is worth noting that the water-stirring rib 220 in this embodiment initially extends obliquely toward the edge of the washing tub 100, then extends upward toward the top of the washing tub 100, parallel to the support column 210, at its distal end. The distal end of the extension abuts the water-stirring pan 230. In the preferred embodiment described above, the initial inclination angle is the angle between the bottom of the washing tub 100 and the line connecting the end of the water-stirring rib 220 and the edge of the washing tub 100.

[0088] In a specific embodiment of this embodiment, the agitating member 200 includes a plurality of agitating ribs 220, which are spaced equidistantly along the circumference of the support column 210. The ends of the agitating ribs 220 at the same height of the support column 210 form a circle, and the radius of the circle formed by the ends of the agitating ribs 220 increases as the support column 210 extends upward. The radius of the circle formed by the ends of the agitating ribs 220 can gradually increase, increase gradually first and then decrease, or initially have a small radius range and then a larger radius range.

[0089] For example, the radial dimension of the water-stirring rib 220 along the washing tub 100 increases first and then decreases from the lower end to the upper end. As a specific embodiment, the cross-sectional shape of the water-stirring rib 220 parallel to the radial direction of the washing tub 100 is approximately spindle-shaped. The outer peripheral edge of the water-stirring rib 220 extends from bottom to top, and the angle between the extension direction and the vertical direction gradually decreases, so that the outer peripheral edge of the water-stirring member 200 forms a curve that bends toward the wall of the washing tub 100. The upper end of the outer peripheral edge of the water-stirring rib 220 coincides with the outer periphery of the water-stirring tray 230. In this embodiment, the number of water-stirring ribs can be set as needed.

[0090] Specifically, as shown in Figure 3, in this embodiment, the water-stirring member 200 includes an assembly portion 210-1 and a water-stirring portion 240 extending upward from the assembly portion 210-1. The assembly portion 210-1 is configured as a solid structure, and the water-stirring portion 240 is at least partially configured as a hollow structure. For example, the water-stirring portion 240 is a cavity configured from the top along the axial direction toward the assembly portion 210-1.

[0091] Specifically, in this embodiment, the assembly portion 210-1 is a solid cylinder, which can increase the connection strength of the water-stirring member 200. The water-stirring portion 240 has an integrally formed hollow structure, which is formed on the top of the assembly portion 210-1. The assembly portion 210-1 can also block the lower end of the hollow structure of the water-stirring portion 240.

[0092] As a specific embodiment, the water-stirring member 200 includes a support column 210, and a water-stirring rib 220 arranged on the side wall of the support column 210, protruding along the radial direction or near radial direction of the support column away from the axis of the support column 210. The water-stirring rib 220 extends along the axial direction of the support column in the length direction, and extends in the width direction away from the circumference of the support column. It can be arranged radially or deviate from the radial direction.

[0093] In this embodiment, the mounting portion 210-1 is a solid column, preferably a circular cylinder, and the hollow column 210-8 extends upward from the upper end surface of the mounting portion 210-1. The outer diameter of the hollow column 210-8 at the connection point with the mounting portion 210-1 can be greater than the radius of the mounting portion 210-1, or less than or equal to the radius of the mounting portion 210-1. The outer wall of the hollow column 210-8 smoothly transitions upward with the outer wall of the mounting portion 210-1.

[0094] The water-stirring portion 240 has a horizontal cross-section with its maximum radius at a predetermined height from the upper end of the assembly portion 210-1. A water-stirring disc 230 is disposed at the top of the support column 210. The maximum radius Rmax of the water-stirring portion 240 is defined by the outer periphery of the water-stirring disc 230, whose top surface is an upwardly convex curved surface. A cavity 210-9 is formed within the hollow column 210-8, similar in shape to the outer shape of the support column 210.

[0095] Preferably, the water stirring rib 220 is also configured as a hollow structure.

[0096] Further preferably, the internal space of the water stirring rib 220 is connected to the cavity 210-9 inside the hollow column 210-8.

[0097] Further preferably, the lower end of the water-stirring rib 220 at least partially extends to the outer peripheral wall of the assembly portion 210 - 1 and is integrally formed with the assembly portion 210 - 1 , thereby further strengthening the strength of the connection between the assembly portion 210 - 1 and the water-stirring portion 240 .

[0098] In this embodiment, the water stirring portion 240 is connected to a stirring shaft rotatably passing through the bottom of the washing tub 100 through the assembly portion 210 - 1 , so that the water stirring member 200 can rotate relative to the washing tub 100 .

[0099] Specifically, the assembly portion 210 - 1 and the stirring shaft are circumferentially positioned by splines and rotate together, and are axially positioned by screws 210 - 7 .

[0100] In this embodiment, the assembly portion 210-1 is provided with a spline groove extending coaxially upward from the bottom end surface of the assembly portion 210-1. The spline groove is at least partially sleeved on the upper end portion of the agitator shaft and is keyed to the agitator shaft. The spline groove is formed on the assembly portion 210-1 of the water-stirring member 200.

[0101] In this embodiment, the top of the agitating member 200 is provided with an opening that communicates with the cavity 210-9 within the hollow column. A screw 210-7 passes through the opening and enters the cavity 210-9, downwardly engaging the agitating shaft keyed to the assembly portion 210-1, thereby axially securing the agitating member 200 to the agitating shaft. To prevent water from entering the cavity 210-9, a sealing member is installed at the opening.

[0102] Preferably, a sealing groove 210-4 is provided on the top of the water stirring member 200. The sealing groove 210-4 is formed by being coaxially recessed downward from the top surface of the water stirring plate 230. An opening communicating with the mold cavity 210-9 is provided at the bottom of the sealing groove 210-4.

[0103] Specifically, the upper end of the assembly portion 210-1 is provided with a through-hole, preferably a threaded hole. The shaft of a screw 210-7 passes through the top of the assembly portion 210-1 and is tightened in the threaded hole, with the head of the screw 210-7 abutting the top of the assembly portion 210-1. Operators remove and install 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 screw.

[0104] The sealing groove 210 - 4 is provided with a sealing cover 210 - 5 for sealing the upper end of the water-stirring member 200 to prevent washing water from entering the interior of the water-stirring member 200 .

[0105] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion. The flat plate portion covers the notch of the sealing groove 210-4 and is embedded in the top of the water-stirring component 200. The inserting portion is inserted into the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0106] The top of the flat plate portion and the top of the water-stirring member 200 are in the same plane.

[0107] The sealing groove 210-4 includes a first section and a second section with increasing diameter from top to bottom. The lower end of the plug-in part is provided with a limiting protrusion protruding from the outer wall of the lower end of the plug-in part in the direction away from the axis of the water-stirring component 200. The limiting protrusion is engaged at the junction between the first section and the second end.

[0108] Preferably, the inner wall of the first section and the inner wall of the second section of the sealing groove 210-4 are transitionally connected by a tapered surface that tilts downward from top to bottom away from the axis of the water-stirring member 200. The shape of the limiting protrusion matches the shape between the first and second sections of the sealing groove 210-4. The outer circumferential surface of the limiting protrusion fits with the inner wall of the second section, and the top of the limiting protrusion fits with the tapered surface between the first and second sections of the limiting groove. Preferably, the bottom of the limiting protrusion is configured as a tapered surface with a gradually decreasing outer diameter from top to bottom, and the outer diameter of the bottom of the limiting protrusion is smaller than the inner diameter of the notch of the sealing groove 210-4.

[0109] In this embodiment, a sealing ridge extending circumferentially along the central portion of the plug-in portion is provided, and the plug-in portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 via the sealing ridge. Preferably, the sealing ridge extends circumferentially along the plug-in portion and is provided with multiple circles spaced apart along the axial direction of the plug-in portion.

[0110] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring member 200 to improve the smoothness of the insertion of the sealing cover 210 - 5 .

[0111] In this embodiment, the upper surface of the agitator rib abuts the inner surface of the agitator tray, and the contact area is coated with flexible material 260. Furthermore, since the agitator rib is a plate-like structure, its outer edge and both sides of the rib are coated with flexible material 260. In other words, in this embodiment, the areas of the agitator rib that come into contact with clothing are all coated with flexible material 260, further reducing friction between the rib and clothing.

[0112] Because the agitating ribs 220 have the aforementioned structure, a Coanda effect is created during washing, driving the water flow along the outer edges of the agitating ribs 220. This results in the water flow tending to follow the outer edges of the agitating ribs 220 in the area near the axis of the washing tub 100. As the height increases, the water flow tends to flow upward rather than outward. This enhances the lifting force of the water flow on the clothes near the axis, driving the clothes upward along the second guide surface 214 to the first guide surface 213, ultimately forming a circular motion path.

[0113] It can be understood that the clothes moving along the bottom of the barrel toward the central area can also be lifted along the outer edge of the water-stirring rib 220 after contacting the water-stirring rib 220. After moving to the maximum radius section Dmax of the water-stirring component 200, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom of the barrel along the wall of the washing barrel 100.

[0114] In the above structure, the radius of any horizontal cross-section of the stirring portion 240 specifically refers to the distance from the center axis to the point at which the stirring rib 220 is furthest from the axis on that horizontal cross-section. When the number of stirring ribs 220 is even, the length of the line connecting the points at which two opposing stirring ribs 220 are furthest from the axis is the diameter of the horizontal cross-section of the stirring portion 240. When the number of stirring ribs 220 is odd, there are no opposing stirring ribs 220. In this case, the horizontal cross-section of the stirring portion 240 does not form an axisymmetric shape, but the diameter of the horizontal cross-section of the stirring portion 240 is still twice the radius determined above.

[0115] In another embodiment, the agitating ribs extend spirally along the sidewall surrounding the support column. In this case, the horizontal cross-section of the agitating portion may not form a regular geometric shape, but the radius of the horizontal cross-section of the agitating portion is still the distance from the farthest end of the agitating ribs from the axis to the central axis on that cross-section.

[0116] In this embodiment, the water stirring tray 230 has an extended height in the central axis direction of the washing tub 100 , and the maximum radius section Dmax is located on the water stirring tray 230 .

[0117] As shown in Figures 4-5 , in one specific embodiment of this embodiment, the water-stirring member is an umbrella-shaped structure, with the support column 210 serving as the umbrella's handle and the water-stirring pan 230 serving as the umbrella's canopy. In this water-stirring member 200, the radius of the water-stirring pan 230 decreases from bottom to top, with the maximum radius Dmax located at the lowest end of the water-stirring pan 230. Because the water-stirring ribs 220 are spaced apart circumferentially around the support column 210, the highest end of the water-stirring ribs 220 is positioned below the water-stirring pan 230.

[0118] The upper surface of the water stirring tray 230 is a curved surface with the middle region higher than the outer region. Specifically, the middle region of the upper portion of the water stirring tray has a sealing cover 210-5 that is higher than the upper surface, and the outer region of the sealing cover 210-5 is a downwardly extending curved surface. The outer region of the sealing cover 210-5 is covered with a flexible material 260.

[0119] In order to further increase the contact area between the water stirring member 200 and the clothes to be washed, a raised stirring portion 231 is provided on the curved surface. In order to further reduce the friction between the water stirring member 200 and the clothes, the outer surface of the stirring portion is wrapped with a flexible material 260.

[0120] The stirring portion has a certain extension length, one end of which is arranged close to the central area of ​​the upper surface of the water stirring tray, and the other end of which is extended toward the edge of the water stirring tray.

[0121] More specifically, as shown in Figure 4, the stirring portion 231 is in the shape of a rocket. The rocket body is positioned near the center of the upper surface of the water-stirring pan 230, while the rocket head extends toward the edge of the water-stirring pan 230. In this embodiment, multiple stirring portions 231 are spaced apart on the upper surface of the water-stirring pan 230. As the clothes are washed, the stirring portions 231 rotate with the water-stirring member 200, stirring the wash water above the water-stirring pan 230. Furthermore, the clothes rub against the surfaces of the multiple stirring portions 231, resulting in a cleaner wash.

[0122] In a preferred embodiment, the uppermost end of the water-stirring rib 220 is fixedly abutted against the inner surface of the water-stirring tray 230 .

[0123] It is worth noting that, in this embodiment, the distance between the outermost perimeter of the agitating rib 220 and the mounting post is less than the radius of the maximum radius segment Dmax of the agitating pan 230. In other words, the radius of the maximum radius segment Dmax of the agitating pan 230 is greater than or equal to the radius of the circle formed by the outer perimeter of the agitating rib 220.

[0124] In this embodiment, the maximum radius section Dmax can be set at any height position along the extension of the water stirring tray 230. The water stirring tray 230 can be divided into three sections along its height: a lower area, a middle area, and an upper area. The maximum radius section Dmax can be set in any of these areas. In other words, the radius of the end cap can gradually decrease, gradually increase, or first gradually increase and then gradually decrease along the extension of the height of the water stirring tray 230.

[0125] For example, the water-stirring pan 230 is composed of two parts. One part is a cylindrical structure that extends upward from the water-stirring ribs 220, and the other part is a conical structure with a gradually decreasing radius at the end of the cylindrical structure. In this embodiment, the maximum radius section Dmax is still located in the lower area of ​​the water-stirring pan 230.

[0126] For example, as shown in FIG7 , the water stirring plate 230 is a disc-shaped structure disposed above the water stirring rib.

[0127] For example, the water stirring pan 230 is a structure in which the radius gradually increases from bottom to top and then gradually decreases. In this solution, the maximum radius section Dmax is equivalent to the middle area of ​​the water stirring pan 230.

[0128] For example, as shown in Figure 9, the water-stirring pan 230 is composed of two parts. One part is a truncated cone-shaped structure that extends upward from the water-stirring rib 220, and the other part is a conical structure with a gradually decreasing radius at the end of the truncated cone. In this embodiment, the maximum radius section Dmax is still located in the lower area of ​​the water-stirring pan 230.

[0129] The water stirring tray may also be in an irregular shape as shown in FIG8 .

[0130] In other embodiments of this embodiment, the shape of the water stirring tray 230 may be regular or irregular. For example, the cross-section of the water stirring tray 230 at a certain height may be a circle, an ellipse, a triangle, a square, a rectangle, a polygon with equal sides, a polygon with unequal sides, or an irregular shape consisting of semicircles of different radii.

[0131] Of course, since the water stirring tray 230 has a certain thickness, the cross-sectional shapes at different thickness positions may be different.

[0132] In the above embodiment, the water stirring member is made of plastic, and the flexible material 260 surrounding the water stirring member is made of rubber or silicone. The water stirring member and the flexible material 260 can be connected together using double injection molding. In addition, to make the water stirring member more prominent within the washing tub, the flexible material 260 can be colored.

[0133] The water-stirring member provided in this embodiment has its outer surface wrapped with the flexible material 260, thereby reducing the friction between the water-stirring member and the clothes to be washed, making the clothes less likely to become linted.

[0134] In the solution of this embodiment, the washing tub and outer tub 100-1 of the washing machine are designed to be parallel to the horizontal plane, and the gap between the two is larger than the radius of the cleaning particles 270, so that the cleaning particles 270 can move smoothly in the gap with the movement of water to clean the tub wall.

[0135] The washing machine further comprises an assembly portion coaxially arranged with the bottom of the washing tub, and the water stirring member is connected with the bottom of the tub via the assembly portion.

[0136] Specifically, the support column 210 is coaxially arranged with the assembly portion 210 - 1 , and the support column 210 extends upward from the top of the assembly portion 210 - 1 . In other words, the upper end of the assembly portion 210 - 1 is connected to the lower end of the support column 210 .

[0137] The water stirring member 200 is arranged in the washing tub 100 and extends upward from the bottom of the washing tub 100 along its axial direction. The water stirring plate on the water stirring member 200 has a maximum radius section Dmax at one of its extended heights. There is a distance between the maximum radius section Dmax and the inner surface of the bottom of the washing tub 100, and the height value of the distance is greater than a preset value. In the solution of the present invention, since the height value of the distance 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 distance, and the stains at the distance can be washed away, thereby avoiding the accumulation of dirt and grime in the distance. In addition, since there is a distance between the maximum radius section Dmax and the inner surface of the washing tub 100, the clothes to be washed can be washed within the distance.

[0138] 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 a circle formed by taking a cross section of the water-stirring member 200 in a direction perpendicular to its rotation axis and taking the rotation center as the center at the maximum distance from the rotation center on the cross section.

[0139] In this solution, no pulsator is provided at the bottom of the washing tub 100 , and the clothes to be washed directly come into contact with the inner surface of the bottom of the washing tub 100 .

[0140] In this solution, since there is no impeller at the bottom of the washing tub 100, and a gap is set 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 flush the gap, thereby avoiding dirt accumulation between the water stirring member 200 and the bottom of the washing tub 100.

[0141] The solution of this embodiment also includes: 10 cm. That is, the distance between the maximum radius section of the water stirring member and the inner surface of the bottom of the washing tub is at least 10 cm, thereby ensuring that the clothes C have enough washing space.

[0142] More specifically, the washing tub includes a bottom 100-a disposed at the bottom and a tub body 100-b disposed above the bottom, and the maximum radius section of the water stirring member is disposed above the highest point of the bottom 100-a. In other words, the maximum radius section is disposed in the tub body 100-b and is a certain distance away from the highest point of the bottom 100-a.

[0143] Of course, to ensure that clothes can be washed within this spacing, the value of this spacing can be adjusted based on actual conditions. Specifically, to divide the washing tub 100 into two washing spaces, the preset value of the spacing can be increased. In other words, the distance between the maximum radius Dmax of the water-stirring member 200 and the bottom of the washing tub 100 can be increased, allowing some clothes to be washed within this area. The preset value and the specific distance between the maximum radius Dmax of the water-stirring member 200 and the bottom of the washing tub 100 in the finished product can be determined based on actual needs and are not specifically limited in this embodiment.

[0144] In the specific solution of this embodiment, the radius of the connection between the assembly portion 210-1 and the support column 210 is the same, and the two are integrally formed. Of course, in other solutions of this embodiment, the shape of the assembly portion 210-1 can be other than cylindrical, and solutions with a radius slightly larger than the radius of the support column 210 are also within the scope of protection of the present invention.

[0145] When the support column 210 is a cylindrical structure, and the radius of the cylindrical structure is the same along its extension direction, the support column 210 extends upward from the top of the assembly portion 210-1, and a water stirring tray 230 is provided at the extension end.

[0146] When the support column includes a first extension section 211 and a second extension section 212 connected to each other, the first extension section is connected to the assembly portion.

[0147] In this embodiment, the washing machine includes a flange mounted on the outside of the washing tub bottom and a drive mechanism mounted outside the outer tub 100-1, with an agitator shaft mounted on the drive mechanism. The bottom of the washing tub 100 has a mounting opening extending through the bottom. The agitator shaft of the drive mechanism passes through the flange, the mounting opening, and the interior of the mounting portion 210-1, where it connects to the water-stirring member 200. When the washing machine performs a washing operation, the agitator shaft drives the mounting portion, causing the water-stirring member 200 to rotate.

[0148] In one solution of this embodiment, the bottom of the washing barrel has a groove-like structure 250 extending downward. The bottom of the washing barrel is almost flush with the horizontal plane, and the middle area of ​​the bottom is recessed downward to form a groove-like structure 250. A mounting opening is provided on the bottom surface of the groove-like structure 250, and the stirring shaft of the driving device is connected to the water-stirring member 200 by passing through the mounting opening and inserting the assembly part 210-1 vertically arranged in the groove-like structure 250. The upper end of the assembly part 210-1 is flush with the inner surface of the barrel bottom. That is to say, in this solution, the lower end of the support column 210 is also flush with the inner surface of the barrel bottom. Since the water-stirring rib 220 is arranged on the support column 210 and is connected to one end of the support column 210, the lower end of the water-stirring rib 220 abuts against the inner surface of the barrel bottom.

[0149] As shown in Figure 7, in another embodiment of the present invention, the bottom of the washing tub has a downwardly extending groove-like structure 250. The bottom of the washing tub is nearly flush with the horizontal plane, with a recessed center area forming the groove-like structure 250. A mounting opening is provided on the bottom of the groove-like structure 250. The agitator shaft of the drive device is inserted through the mounting opening into a mounting portion 210-1 vertically disposed within the groove-like structure 250, thereby connecting to the agitator member 200. The mounting portion 210-1 is vertically disposed and protrudes from the groove-like structure 250, extending above the inner surface of the tub bottom. The mounting portion comprises two interconnected parts: a first portion and a second portion. The first portion is vertically disposed within the groove-like structure 250 and connected to the agitator shaft, while the second portion protrudes from the inner surface of the tub bottom and connects to the support column 210. In this embodiment, the radius of the groove-like structure 250 is slightly larger than the radius of the mounting portion. More specifically, the radius of the groove-like structure 250 is slightly larger than the radius of the mounting portion, i.e., the radius of the first portion, which is mounted within the groove-like structure 250.

[0150] That is to say, in this solution, the upper end of the second portion of the assembly portion is at a certain distance from the inner surface of the barrel bottom, so the lower end of the water stirring rib 220 is also at a certain distance from the inner surface of the barrel bottom.

[0151] In this embodiment, the outer periphery of the assembly portion is covered with flexible material 260. Specifically, the outer periphery of the portion protruding from the groove structure 250 and higher than the inner surface of the barrel bottom is wrapped with flexible material 260, that is, the outer periphery of the second portion of the assembly portion is wrapped with flexible material 260.

[0152] In this embodiment, the lowest end of the water-stirring rib 220 does not directly contact the bottom of the washing tub. Instead, it is spaced apart from the inner surface of the bottom via the mounting portion. Therefore, when the agitator shaft rotates the water-stirring member, the water-stirring rib 220 does not rub against the inner surface of the washing tub bottom, thereby preventing increased friction between the rotating water-stirring member and the bottom of the washing tub.

[0153] In this embodiment, a groove-like structure is formed in the middle of the washing tub. Several water holes are provided between the outer periphery of the groove and the surrounding wall of the washing tub, allowing water from the washing tub to flow into the outer tub 100-1. The inner diameter of the water holes is smaller than the radius of the cleaning particles 270, thereby preventing the cleaning particles 270 from entering the washing tub from between the washing tub and the outer tub 100-1.

[0154] Of course, in other solutions of this embodiment, the groove-shaped structure 250 may not be provided on the bottom of the washing tub, and the mounting opening may be directly provided on the surface of the bottom, with the mounting portion directly protruding from the inner surface of the bottom. In other words, the lower end of the support rib is at a certain distance from the inner surface.

[0155] In the above embodiment, the lowest end of the water-stirring rib 220 does not directly contact the bottom of the washing tub 100, but is instead spaced apart from the inner surface of the bottom. Therefore, during use, when the agitator shaft rotates the water-stirring rib 220, the water-stirring rib 220 does not rub against the inner surface of the bottom of the washing tub 100, thereby preventing increased friction between the water-stirring rib 220 and the bottom of the washing tub 100. Furthermore, this prevents any blind spots from forming between the water-stirring rib 220 and the bottom of the washing tub.

[0156] The solution of this embodiment also includes: a receiving chamber 280 connected to the outer barrel 100-1 for collecting cleaning particles 270 is provided at the lower part of the washing device;

[0157] When draining, the cleaning particles 270 enter the accommodating chamber 280 from between the outer tub 100 - 1 and the washing tub; when water is entering, the cleaning particles 270 enter the accommodating chamber 280 from between the outer tub 100 - 1 and the washing tub.

[0158] The accommodating chamber 280 is in communication with the drain pipe 300 , and a filter device 290 for blocking the cleaning particles 270 is provided between the two.

[0159] The washing device includes a drain valve 310 disposed above the drain pipe 300 . The drain valve 310 closes or opens the drain pipe 300 by abutting against or moving away from the wall of the accommodating chamber 280 on the side where the filter device 290 is located.

[0160] A chamber 280 for collecting cleaning particles 270 is located below the bottom wall of the washing machine's outer tub 100-1. This chamber 280 communicates with the outer tub 100-1 through an opening in the bottom wall. Furthermore, chamber 280 communicates with a drain pipe 300, and a filter 290 is located between the drain pipe 300 and chamber 280 to block cleaning particles 270.

[0161] Specifically, filter device 290 is a filter screen positioned to the right of accommodating chamber 280. A drain valve 310 is mounted to the right of the filter screen. A valve plug is mounted on drain valve 310, and below the valve plug is the water inlet of drain pipe 300. When the washing machine is performing a wash cycle, the valve plug of drain valve 310 moves into accommodating chamber 280, blocking the water inlet of drain pipe 300. Water enters the washing tub, allowing cleaning particles 270 to flow from accommodating chamber 280 into the space between outer tub 100-1 and the washing tub. When washing is complete, the valve plug of drain valve 310 moves away from accommodating chamber 280, opening the water inlet of drain pipe 300. The cleaning particles 270 are then stored in accommodating chamber 280, flowing through the space between outer tub 100-1 and the washing tub.

[0162] It is worth noting that, in this solution, there is no bottom disc-shaped stirring portion.

[0163] In this embodiment, the outer edge of the water-stirring rib 220 is curved and is provided with a flexible material 260. Because there is no dial in the wash tub, the projection of any position of the outer edge perpendicular to the tub bottom directly and unobstructedly rests on the inner surface of the bottom of the wash tub 100. Any position of the outer edge of the water-stirring rib 220 extends vertically downward to the inner tub bottom, contacting the inner surface of the inner tub bottom.

[0164] Since the water-stirring ribs 220 in this embodiment are arranged at intervals along the circumference of the support column 210, the outer edges of several water-stirring ribs at any position perpendicular to the support column are connected to form a circle, and the projection of any position on the circumference of the circle vertically to the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0165] Since the water-stirring ribs are plate-shaped structures, the opposite sides of any two adjacent water-stirring ribs are wrapped with the flexible material 260 .

[0166] In the solution of this embodiment, a circle is drawn with the vertical distance between the edge where the maximum radius of the water-stirring rib 220 is located and 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 circle. No dial is set in the circular area formed between the position where the circular edge is projected vertically to the bottom of the barrel and the outer periphery of the support column 210.

[0167] Similarly, the circular area formed by the edge of the maximum radius segment Dmax on the water stirring plate 230 and the circular area formed between the position where the circular edge is projected vertically to the bottom of the barrel and the outer periphery of the support column 210 is not provided with a dial.

[0168] This embodiment also includes a solution where the depth of the washing tub 100 is H, and a distance of h is defined between the maximum radius section Dmax of the water-stirring disc 230 of the water-stirring member 200 and the inner surface of the tub bottom. The distance h and the depth H of the washing tub 100 satisfy the following relationship: h / H ≥ 1%. Extensive prior testing has shown that when the distance h and the depth H of the washing tub 100 meet this ratio, the best effect in preventing dirt and grime from accumulating between the water-stirring member 200 and the washing tub 100 is achieved.

[0169] Of course, in other solutions of this embodiment, the ratio of the height h of the interval to the height H of the washing tub 100 may also be greater than or equal to other values.

[0170] In this solution, in order to ensure the washing space for clothes, the maximum radius section Dmax on the water stirring tray 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 drum.

[0171] This embodiment provides a solution that not only places cleaning particles 270 between the outer tub 100-1 and the washing tub, keeping them clean, but also eliminates the need for a dial inside the washing machine, thereby preventing dirt from accumulating between the agitator and the floor of the washing tub. This solution prevents residual stains or bacteria from contaminating the laundry, improving the user experience.

[0172] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
