Description

Technical Field

[0001] This utility model belongs to the field of washing equipment, specifically, it relates to the water agitation component and washing tub assembly of washing equipment. Background Technology

[0002] Washing machines, as a convenient garment cleaning device, have become widely used in people's lives. Currently available washing machines are divided into front-loading and top-loading types, with top-loading washing machines being more popular due to their superior cleaning performance.

[0003] A top-loading washing machine typically contains an inner tub and a pulsator, with the pulsator located at the bottom of the inner tub. When the washing machine is operating, the rotation of the pulsator causes the washing water inside the inner tub to swirl, thus washing the clothes inside.

[0004] During the washing process, clothes come into contact with and rub against the pulsator. Since pulsators are generally made of plastic, the friction on the clothes is relatively high, which can easily cause pilling on the surface of the clothes, especially for clothes made of certain materials that are prone to pilling.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water agitation component and washing tub assembly of a washing device that reduces friction on clothes and makes them less prone to pilling.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] On the one hand, a water-stirring component for a washing device is provided.

[0009] The water-stirring component includes a support column with a certain extension length, and a water-stirring plate extending to one end of the support column at a certain length of the support column; the water-stirring plate has a maximum radius segment at a certain extension position, and there is a gap between the maximum radius segment and the other end of the support column.

[0010] The outer surface of the water-stirring component is at least partially covered with a flexible material.

[0011] Furthermore, the support column is provided with a number of water-stirring ribs, the inner edge of which extends along the axial direction of the support column and the outer edge extends radially outward along the support column.

[0012] The outer surface of the support column and / or the water-stirring rib is at least partially covered with a flexible material.

[0013] Furthermore, the water stirring plate is an umbrella-shaped structure set at one end of the support column, and the middle area of ​​the upper part of the water stirring plate has a sealing cover that is higher than the upper surface, and the outer periphery of the sealing cover is a downwardly extending curved surface.

[0014] The sealing cap is made of flexible material and / or the outer periphery of the sealing cap is wrapped with flexible material.

[0015] Furthermore, several raised stirring sections are provided on the curved surface;

[0016] The stirring part has a certain extension length, with one end located near the center area of ​​the upper surface of the stirring plate and the other end extending towards the edge of the stirring plate.

[0017] The outer surface of the stirring section is covered with a flexible material.

[0018] Furthermore, the support column is provided with a number of water-stirring ribs, the inner edge of which extends along the axial direction of the support column and the outer edge extends obliquely toward the inner surface of the water-stirring plate.

[0019] The outer surface of the water-stirring rib is at least partially covered with a flexible material.

[0020] On the other hand, a washing tub assembly including the water agitation component of the aforementioned washing device is also provided.

[0021] The washing tub assembly includes a washing tub, one end of a support column is fitted with the bottom of the washing tub, and the other end, which is provided with a water agitator, extends upward from the bottom of the tub. There is a gap between the maximum radius section and the inner surface of the bottom of the tub, allowing clothes to be washed within this gap.

[0022] Furthermore, the support column extends upward from the top of the assembly part that is coaxially arranged with the bottom of the barrel;

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

[0024] The bottom surface of the trough structure is provided with an installation port, through which the stirring shaft passes and is inserted into the assembly part to connect with the water stirring component.

[0025] The portion of the assembly part that protrudes from the groove structure and is higher than the inner surface of the bottom of the barrel is wrapped with flexible material.

[0026] Furthermore, a number of water-stirring ribs are spaced apart on the outer periphery of the support column. The outer edge of the water-stirring ribs is made of flexible material, and the projection of any position of the outer edge vertically toward the bottom of the tub is directly located on the inner surface of the bottom of the washing tub.

[0027] Furthermore, the opposite sides of any two adjacent water-stirring ribs are wrapped with flexible material;

[0028] The outer edges of several agitator 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 this circle perpendicularly to the bottom of the tub is directly located on the inner surface of the bottom of the washing tub.

[0029] Furthermore, the support column comprises two parts, namely a first extension section and a second extension section connected together;

[0030] The first extension section is connected to the assembly section and extends upward, with its sidewall forming a second guide surface; the second extension section extends upward from the first extension section, and the radius of the second extension section gradually increases with the increase of height, with its sidewall forming a first guide surface.

[0031] Flexible material is wrapped around the first and second guide surfaces.

[0032] Furthermore, the first extension section has the same radius as the assembly section, and the two are integrally formed.

[0033] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0034] 1. The water-stirring component provided by this utility model has a flexible material on its outer surface in at least a part, which reduces the friction between the water-stirring component and the clothing, making the clothing less prone to pilling.

[0035] 2. The washing tub assembly provided by this utility model has a water-stirring plate on the water-stirring component, and there is a gap between the maximum radius section of the water-stirring plate and the inner surface of the bottom of the washing tub. This allows water to enter the gap and wash away stains during the washing process, preventing dirt and grime from accumulating between the water-stirring component and the bottom of the tub. This solution improves the user experience.

[0036] 3. In the washing tub assembly provided by this utility model, since the projection of the water-stirring rib at any position of its outer edge onto the bottom of the tub is directly located on the inner surface of the bottom of the washing tub, there is no dial at the position where the projection of the water-stirring rib onto the inner surface of the washing tub is located.

Therefore, they should not be construed as limitations on this utility model.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] like Figures 1 to 17 As shown, this utility model provides a water agitation component and a washing tub assembly for a washing device.

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

[0063] The water-stirring component includes a support column with a certain extension length, and a water-stirring plate extending to one end of the support column at a certain length of the support column; the water-stirring plate has a maximum radius segment at a certain extension position.

[0064] The outer surface of the water-stirring component is at least partially covered with a flexible material 260.

[0065] The water-stirring component provided by this utility model has a flexible material 260 wrapped around its outer surface, which reduces the friction between the water-stirring component and the clothes, making the clothes less prone to pilling.

[0066] On the other hand, a washing tub assembly including the water agitation component of the aforementioned washing device is also provided.

[0067] The washing tub assembly includes a washing tub, one end of a support column is fitted with the bottom of the washing tub, and the other end, which is provided with a water agitator, extends upward from the bottom of the tub. There is a gap between the maximum radius section and the inner surface of the bottom of the tub, allowing clothes to be washed within this gap.

[0068] The washing tub assembly provided by this utility model, by including the aforementioned water-agitating component, allows water to enter the gap and wash away stains during the washing process, preventing dirt and grime from accumulating between the water-agitating component and the bottom of the tub. This solution improves the user experience.

[0069] Example 1

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

[0071] The water-stirring component includes a support column with a certain extension length, and a water-stirring plate extending to one end of the support column at a certain length of the support column; the water-stirring plate has a maximum radius segment at a certain extension position.

[0072] The outer surface of the water-stirring component is at least partially covered with a flexible material 260.

[0073] The water-stirring component provided in this embodiment is installed in the washing tub of the washing machine to drive the washing water to rotate and wash the clothes in the washing tub.

[0074] The water-stirring component includes a support column and a water-stirring disc. The support column has a certain extension length, with one end fitting into the bottom of the washing tub and the other end extending towards the opening of the washing tub. One end of the water-stirring disc is positioned at any height of the support column, and the other end extends upwards towards the washing tub. The water-stirring disc has a maximum radius segment, which can be located at any extension height of the water-stirring disc.

[0075] In this embodiment, a flexible material 260 is wrapped around the outer surface of the water-stirring component. This reduces the friction between the water-stirring component and the clothing, making the clothing less prone to pilling.

[0076] Since one end of the agitator is positioned at any height on the support column, and the other end extends upwards towards the washing tub, with the maximum radius at a certain extension point, the agitator has a certain thickness, and the maximum radius is at this arbitrary thickness. The agitator can be shaped like a candied hawthorn skewer or an umbrella-shaped structure. Of course, other shapes are also possible; in this embodiment, the specific shape is not limited. The only requirement is that it can agitate the water flow.

[0077] It should be noted that, in the embodiments of this utility model, the maximum radius segment refers to the radius of the horizontal cross-section of the water-stirring part 240, and the cross-section of the water-stirring part 240 is taken along the horizontal direction (see...). Figure 10 The distance from the point furthest from the center of rotation on the obtained horizontal cross section is the distance from the center of rotation.

[0078] Specifically, if the horizontal cross-section of the water-stirring section 240 is Figure 11 The radius of the circle shown is the radius R1 of the cross-section of that circle. If the horizontal cross-section of the agitator 240 is... Figures 12 to 17 If the shape shown is not circular, then the radius is the distance R2 from the point on the cross section furthest from the center of rotation to the center of rotation (i.e., the position marked by "×" in the figure).

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

[0080] The outer surface of the support column and / or the water-stirring rib is at least partially covered with a flexible material.

[0081] The middle area of ​​the upper part of the water stirring plate has a sealing cover 210-5 that is higher than the upper surface, and the outer periphery of the sealing cover is a downward-extending curved surface;

[0082] The sealing cap is made of a flexible material and / or the outer periphery of the sealing cap is wrapped with a flexible material 260.

[0083] Several raised stirring sections are provided on the curved surface;

[0084] The stirring part has a certain extension length, with one end located near the center area of ​​the upper surface of the stirring plate and the other end extending towards the edge of the stirring plate.

[0085] The outer surface of the stirring section is covered with a flexible material 260.

[0086] The specific structure of the water-stirring component will be described in detail below:

[0087] The water-stirring component includes a support column 210 coaxially arranged with the bottom of the tub, a water-stirring rib 220 arranged on the outer periphery of the support column 210, and a water-stirring plate 230 arranged at the end of the support column 210. That is, one end of the support column 210 is connected to the bottom of the tub, and the other end extends towards the opening of the tub, with the water-stirring plate 230 arranged at its extended end. The water-stirring rib 220 extends obliquely from the outer periphery of the support column 210 away from the water-stirring plate towards the top of the washing tub 100.

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

[0089] In another specific embodiment, the support column 210 comprises two parts: a first extension 211 and a second extension 212 connected together. The first extension 211 extends upward from the bottom of the washing tub 100, and its sidewall forms a second guide surface 214. The second extension 212 extends upward from the first extension 211, and the radius of the second extension 212 gradually increases with increasing height, and its sidewall forms a first guide surface 213. That is, the radii of the first extension 211 and the second extension 212 are not the same. The radius of the first extension 211 remains constant, while the radius of the second extension 212 gradually increases with increasing height. By setting the first extension 211 and the second extension 212, the angle between the upper sidewall of the support column 210 and the lower surface of the agitator 230 is significantly increased, thereby effectively reducing the problem of cleaning dead zones where clothes cannot reach between the upper end of the support column 210 and the lower surface of the agitator 230. Furthermore, in this design, the contact area between the end cap and the support column 210 is increased, making the two more firmly fixed.

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

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

[0092] 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, a flexible material 260 is wrapped around the outer contour, further reducing friction with clothing.

[0093] More notably, in this design, the agitator 220 initially extends at an incline towards the edge of the washing tub 100's opening, and at its extended end, it tends to extend parallel to the support column 210 upwards towards the opening of the washing tub 100. Furthermore, the extended end abuts against the agitator plate 230. In the aforementioned preferred embodiment, the initial inclination angle is the angle between the bottom of the washing tub 100 and the straight line connecting the end of the agitator 220 to the edge of the washing tub 100's opening.

[0094] In this specific embodiment, the water-stirring component 200 includes a plurality of water-stirring ribs 220, which are equidistantly spaced along the circumference of the support column 210. The ends of the water-stirring ribs 220 at the same height position on the support column 210 form a circle, and the radius of the circle formed by the ends of the water-stirring ribs 220 increases along the upward extension direction of the support column 210. The radius of the circle formed by the ends of the water-stirring ribs 220 can gradually increase, or it can first gradually increase and then decrease, or the radius can initially vary within a small range and then vary within a larger range.

[0095] For example, the radial dimension of the agitator 220 along the washing tub 100 first increases and then decreases from the bottom to the top. In one specific embodiment, the cross-sectional shape of the agitator 220 parallel to the radial direction of the washing tub 100 is approximately spindle-shaped. The outer peripheral edge of the agitator 220 extends from bottom to top, and the angle between the extending direction and the vertical direction gradually decreases, causing the outer peripheral edge of the agitator 200 to form a curve that bends towards the tub wall of the washing tub 100. The upper end of the outer peripheral edge of the agitator 220 coincides with the outer periphery of the agitator plate 230. In this design, the number of agitators can be set according to requirements.

[0096] In this design, the upper surface of the water-stirring rib abuts against the inner surface of the water-stirring disc, and the area in contact is covered with a flexible material 260. Furthermore, since the water-stirring rib has a plate-like structure, its outer edge and both sides are covered with the flexible material 260. In other words, in this design, the area of ​​the water-stirring rib that contacts the clothing is covered with the flexible material 260, thereby further reducing friction between it and the clothing.

[0097] Because the agitator 220 has the aforementioned structure, it can create a Coanda effect during washing, causing water to flow along the outer periphery of the agitator 220. This results in the water flow tending to conform to the outer periphery of the agitator 220 in the area near the axis of the washing tub 100. As the height increases, the direction of water flow becomes more upward rather than outward. This enhances the lifting force of the water flow on the clothes in the area near the axis, causing the clothes to move upward along the second guide surface 214 to the first guide surface 213, ultimately forming a circular motion path.

[0098] Understandably, clothes moving from the bottom of the tub towards the center can also be lifted along the outer edge of the agitator 220 after contacting it. After moving to the maximum radius segment Dmax of the agitator 200, they move outward under the action of inertia and centrifugal force, and finally fall down to the bottom of the tub along the wall of the washing tub 100.

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

[0100] In the above structure, the radius of any horizontal section of the water-stirring part 240 specifically refers to the distance from the farthest point of the water-stirring rib 220 from the axis to the central axis on that horizontal section. When the number of water-stirring ribs 220 is even, the length of the line connecting the farthest points of two opposite water-stirring ribs 220 from the axis is the diameter of the horizontal section of the water-stirring part 240. When the number of water-stirring ribs 220 is odd, there are no oppositely arranged water-stirring ribs 220. In this case, the horizontal section of the water-stirring part 240 does not form an axisymmetric figure, but the diameter of the horizontal section of the water-stirring part 240 is still twice the radius determined above.

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

[0102] like Figure 3 As shown, in one specific embodiment, the water-stirring component is an umbrella-shaped structure, with the support column 210 corresponding to the umbrella handle and the water-stirring plate 230 corresponding to the umbrella canopy. In this water-stirring component 200, the radius of the water-stirring plate 230 decreases from bottom to top, and the maximum radius segment Dmax on the water-stirring plate 230 is located at the bottom of the water-stirring plate 230. Since the water-stirring ribs 220 are spaced apart along the circumference of the support column 210, the uppermost end of the water-stirring ribs 220 is positioned below the water-stirring plate 230.

[0103] like Figure 8As shown, in this embodiment, the middle area of ​​the agitator is recessed to form a sealing groove 210-4. Screws enter the sealing groove 210-4 and pass through its bottom to be fixedly connected to the mounting post. The sealing cap is made of flexible material and is partially inserted into the screw sealing groove 210-4 to prevent water from entering and corroding the screw.

[0104] The upper surface of the stirring plate 230 is a curved surface where the middle region is higher than the outer periphery. That is, the middle region of the upper part of the stirring plate has a sealing cap 210-5 that is higher than the upper surface, and the outer periphery of the sealing cap is a downward-extending curved surface. Furthermore, a flexible material 260 is applied to the outer periphery of the sealing cap.

[0105] To further increase the contact area between the water-stirring component 200 and the clothes to be washed, a raised stirring part 231 is provided on the curved surface. To further reduce friction between the stirring part and the clothes, the outer surface of the stirring part is covered with a flexible material 260.

[0106] The stirring part has a certain extension length, with one end located near the center area of ​​the upper surface of the stirring plate and the other end extending towards the edge of the stirring plate.

[0107] More specifically, such as Figure 1 As shown, the stirring part 231 is rocket-shaped, with one end containing the rocket body positioned near the center of the upper surface of the stirring plate 230, and the other end containing the rocket head extending towards the edge of the stirring plate 230. In this design, multiple stirring parts 231 are spaced apart on the upper surface of the stirring plate 230. This allows the stirring parts 231 to agitate the washing water above the stirring plate 230 as the stirring component 200 rotates during the washing process, and also enables the clothes to rub against the surfaces of the multiple stirring parts 231, resulting in cleaner clothes.

[0108] In the preferred embodiment, the uppermost end of the water-stirring rib 220 is fixed in contact with the inner surface of the water-stirring plate 230.

[0109] It is worth noting that in this design, the distance between the outermost contour of the water-stirring rib 220 and the mounting column is less than the radius of the maximum radius segment Dmax of the water-stirring disc 230. In this embodiment, the maximum radius segment Dmax can be set at any position at the extended height of the water-stirring disc 230. The water-stirring disc 230 can be divided into three parts along the extension direction of its height: a lower region, a middle region, and an upper region. The maximum radius segment Dmax can be set in any one of these three regions. That is, the radius of the end cap can gradually decrease, gradually increase, or first gradually increase and then gradually decrease along the extension direction of the water-stirring disc 230's height.

[0110] For example, the stirring plate 230 is composed of two parts. One part is a cylindrical structure that extends upwards and abuts against the stirring rib 220, and the other part is a conical structure whose radius gradually decreases at the end of the cylindrical structure. In this design, the maximum radius segment Dmax is still located in the lower region of the stirring plate 230.

[0111] For example, such as Figure 4 As shown, the water stirring plate 230 is a disc-shaped structure disposed above the water stirring rib.

[0112] For example, the stirring plate 230 has a structure where the radius gradually increases from bottom to top and then gradually decreases. In this design, the maximum radius segment Dmax corresponds to the central region of the stirring plate 230.

[0113] For example, such as Figure 6 As shown, the stirring plate 230 is composed of two parts. One part is a frustum-shaped structure that extends upwards and abuts against the stirring rib 220, and the other part is a conical structure whose radius gradually decreases at the end of the frustum-shaped structure. In this design, the maximum radius segment Dmax is still located in the lower region of the stirring plate 230.

[0114] The stirring plate can also be as follows: Figure 5 The irregular shape shown.

[0115] In other embodiments of this invention, the shape of the stirring plate 230 can be regular or irregular. For example, the cross-section of the stirring plate 230 at a certain height can be a circle, an ellipse, a triangle, a square, a rectangle, a polygon with equal side lengths, a polygon with unequal side lengths, or an irregular shape composed of semicircles of different radii.

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

[0117] In the above solution, the water-stirring component is made of plastic, and the flexible material 260 surrounding it is made of rubber or silicone. The water-stirring component and the flexible material 260 can be connected together by double injection molding or by a secondary insertion method. Furthermore, to make the water-stirring component more prominent within the washing tub, the flexible material 260 can be colored. For better washing results, the flexible material is antibacterial.

[0118] The water-stirring component provided in this embodiment has a flexible material 260 wrapped around its outer surface, which reduces friction with the clothes to be washed, making the clothes less prone to pilling.

[0119] Example 2

[0120] like Figure 7 As shown, this embodiment provides a washing tub assembly that includes the water-stirring component of the washing equipment described in the above embodiment.

[0121] The solution of this embodiment includes: a washing tub assembly including a washing tub, one end of a support column being fitted with the bottom of the washing tub, and the other end having a water agitator extending upward from the bottom of the tub, with a gap between the maximum radius section and the inner surface of the bottom of the tub, allowing clothes to be washed within this gap.

[0122] The support column extends upward from the top of the assembly part that is coaxial with the bottom of the barrel.

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

[0124] The bottom surface of the trough structure 250 is provided with an installation port, and the stirring shaft passes through the installation port and is inserted into the assembly part to connect with the water stirring component.

[0125] The portion of the assembly part that protrudes from the groove structure 250 and is higher than the inner surface of the bottom of the barrel is wrapped with a flexible material 260.

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

[0127] The first extension section is connected to the assembly section and extends upward, with its sidewall forming a second guide surface; the second extension section extends upward from the first extension section, and the radius of the second extension section gradually increases with the increase of height, with its sidewall forming a first guide surface.

[0128] Flexible material 260 is wrapped around the first and second guide surfaces.

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

[0130] The washing tub components will now be described in detail:

[0131] The washing tub assembly provided in this embodiment includes a water agitator, which is rotatably disposed inside the washing tub. The water agitator 200 can rotate relative to the washing tub 100, or can rotate together with the washing tub 100 in the same or opposite direction.

[0132] The washing tub assembly also includes an assembly part coaxially arranged with the tub bottom. The water agitator is connected to the tub bottom via the assembly part.

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

[0134] The water-stirring component 200 extends axially upward from the bottom of the washing tub 100 and is disposed within the washing tub 100. The water-stirring disc on the water-stirring component 200 has a maximum radius segment Dmax at one extension height. A gap exists between the maximum radius segment Dmax and the inner surface of the bottom of the washing tub 100, and the height of this gap is greater than a preset value to prevent dirt and grime from accumulating at this gap. In this design, the washing space refers to the spatial area that the clothing C can reach during the washing process.

[0135] It should be noted that, in the embodiments of this utility model, the radius of the water-stirring component 200 refers to the radius of the circle formed by taking a cross section of the water-stirring component 200 along a direction perpendicular to its rotation axis, with the rotation center as the center of the circle at the point where the distance from the rotation center is the greatest.

[0136] More specifically, such as Figure 9 As shown, in this embodiment, the water-stirring component 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 has a cavity provided axially from its top end toward the assembly portion 210-1.

[0137] Specifically, in this embodiment, the assembly part 210-1 is a solid column, which can increase the connection strength of the water-stirring component 200. The water-stirring part 240 has an integrally formed hollow structure, and the water-stirring part 240 is formed on the top of the assembly part 210-1. The assembly part 210-1 can also seal the lower end of the hollow structure of the water-stirring part 240.

[0138] In one specific embodiment, the water-stirring component 200 includes a support column 210 and a water-stirring rib 220 disposed 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 or near-radial direction. The water-stirring rib 220 extends along the axial direction of the support column in the length direction and extends in a direction away from the outer periphery of the support column in the width direction. It can be arranged radially or deviated from the radial direction.

[0139] In this embodiment, the assembly part 210-1 is a solid cylinder, preferably a round cylinder, and the hollow column 210-8 extends upward from the upper end surface of the assembly part 210-1. The outer diameter of the connection between the hollow column 210-8 and the assembly part 210-1 can be greater than the radius of the assembly part 210-1, or it can be less than or equal to the radius of the assembly part 210-1; the outer peripheral wall of the hollow column 210-8 smoothly transitions upward from the outer peripheral wall of the assembly part 210-1.

[0140] The water-stirring part 240 has a horizontal cross-section with the largest radius at a certain height from the upper end of the assembly part 210-1. A water-stirring plate 230 is provided at the top 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 plate 230, and the top surface of the water-stirring plate 230 is an upwardly convex curved surface. The hollow column 210-8 has a cavity 210-9 inside that has a shape similar to the outer shape of the support column 210.

[0141] Preferably, the water-stirring rib 220 is also configured as a hollow structure.

[0142] More preferably, the internal space of the water-stirring rib 220 is connected to the cavity 210-9 inside the hollow column 210-8.

[0143] More preferably, the lower end of the water-stirring rib 220 extends at least partially 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 between the assembly part 210-1 and the water-stirring part 240.

[0144] 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 via the assembly part 210-1, so that the water stirring component 200 can rotate relative to the washing tub 100.

[0145] Specifically, the assembly part 210-1 and the stirring shaft are circumferentially positioned by a spline and rotate together, and are axially positioned by screws 210-7.

[0146] In this embodiment, the assembly part 210-1 is provided with a spline groove extending upward in the same direction as the bottom end face of the assembly part 210-1. The spline groove is at least partially sleeved on the upper end of the stirring shaft and is keyed to the stirring shaft. The spline groove is formed on the assembly part 210-1 of the water stirring component 200.

[0147] In this embodiment, the top of the water-stirring component 200 is provided with an opening communicating with the cavity 210-9 inside the hollow column. The screw 210-7 enters the cavity 210-9 through the opening and connects downwards to the stirring shaft that is keyed in the assembly part 210-1, thus fixing the water-stirring component 200 to the stirring shaft in the axial direction. To prevent water from entering the cavity 210-9, a sealing component is installed at the opening.

[0148] Preferably, a sealing groove 210-4 is provided on the top of the water stirring component 200, and the sealing groove 210-4 is formed by a downward indentation coaxially with the top surface of the water stirring plate 230. An opening communicating with the cavity 210-9 is provided on the bottom of the sealing groove 210-4.

[0149] Specifically, the upper end of the assembly part 210-1 is provided with a through hole, preferably a threaded hole. The shank of the screw 210-7 passes through the top of the assembly part 210-1 and is tightened into the threaded hole, with the head of the screw 210-7 abutting against the top of the assembly part 210-1. The operator can assemble and disassemble the screw 210-7 through the opening on the bottom of the sealing groove 210-4 and the cavity 210-9 of the hollow column 210-8. The screw is preferably a countersunk screw.

[0150] A sealing cover 210-5 is provided at the sealing groove 210-4 to seal the upper end of the water agitator 200, so as to prevent washing water from entering the interior of the water agitator 200.

[0151] Specifically, the sealing cap 210-5 includes a flat plate portion and an insertion portion. The flat plate portion covers the opening of the sealing groove 210-4 and is embedded in the top of the water stirring component 200. The insertion portion is inserted into the sealing groove 210-4 and is interference-fitted with the sealing groove 210-4.

[0152] The top of the flat plate and the top of the water-stirring component 200 are on the same plane.

[0153] 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 insertion part is provided with a limiting protrusion that protrudes from the outer wall of the lower end of the insertion part in a direction away from the axis of the water stirring component 200. The limiting protrusion engages at the junction between the first section and the second end.

[0154] Preferably, the inner walls of the first and second sections of the sealing groove 210-4 are connected by a tapered surface that slopes downwards away from the axis of the agitator 200. The shape of the limiting protrusion is adapted to the shape between the first and second sections of the sealing groove 210-4. The outer circumferential surface of the limiting protrusion fits against the inner wall of the second section, and the top of the limiting protrusion fits against the tapered surface between the first and second sections of the limiting groove. Preferably, the bottom of the limiting protrusion is a tapered surface with an outer diameter that gradually decreases from top to bottom, and the outer diameter of the bottom of the limiting protrusion is smaller than the inner diameter at the opening of the sealing groove 210-4.

[0155] In this embodiment, a sealing ridge extending circumferentially along the middle of the insertion portion is provided, and the insertion portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 through the sealing ridge. Preferably, the sealing ridge extends circumferentially along the insertion portion and is provided in multiple rings spaced apart axially along the insertion portion.

[0156] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring component 200 to improve the smoothness of the insertion of the sealing cap 210-5.

[0157] In this design, no impeller is installed at the bottom of the washing tub 100, and the clothes to be washed come into direct contact with the inner surface of the bottom of the washing tub 100.

[0158] In this design, since no impeller is provided at the bottom of the washing tub 100, and a gap is provided between the maximum radius segment Dmax and the inner surface of the bottom of the washing tub 100, the water flow can wash away the gap during the washing process, thereby preventing dirt from accumulating between the agitator 200 and the bottom of the washing tub 100.

[0159] The solution in this embodiment also includes: the preset value is 10cm. That is, the minimum distance between the maximum radius segment of the water agitator and the inner surface of the bottom of the washing tub is 10cm. This ensures that the clothes C have sufficient washing space.

[0160] More specifically, the washing tub includes a bottom 100-a at the bottom and a body 100-b above the bottom, with the maximum radius of the agitator segment being higher than the highest point of the bottom 100-a. In other words, the maximum radius segment is located within the body 100-b and is at a certain distance from the highest point of the bottom 100-a.

[0161] Of course, in order to ensure that clothes can 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. In other words, the distance between the maximum radius segment Dmax of the water agitator 200 and the 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 segment Dmax of the water agitator 200 and the bottom of the washing tub 100 in the finished product, they can be determined according to the requirements, and no specific limitation is made in this embodiment.

[0162] In this specific embodiment, the assembly part 210-1 and the support column 210 have the same radius at their connection point, and they are integrally formed. Of course, in other embodiments of this invention, the shape of the assembly part 210-1 can be any shape other than cylindrical, and a shape with a radius larger than or slightly larger than the radius of the support column 210 is also within the protection scope of this utility model.

[0163] 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 part 210-1, and a water stirring plate 230 is provided at the extended end.

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

[0165] In this design, a drive unit is installed on the washing equipment, and an agitator shaft is mounted on the drive unit. An installation port is provided at the bottom of the washing tub 100, and this installation port is an opening that penetrates the bottom of the tub. The agitator shaft of the drive unit is inserted into the assembly 210-1 through the installation port and connected to the water agitator 200. When the washing equipment performs a washing operation, the agitator shaft drives the assembly, thereby causing the water agitator 200 to rotate.

[0166] In one embodiment, the bottom of the washing tub has a downwardly extending groove-shaped structure 250. An installation port is provided on the bottom surface of the groove-shaped structure 250. The agitator shaft of the drive device is connected to the water-stirring component 200 by passing through the installation port and inserting into an assembly part 210-1 vertically disposed within the groove-shaped structure 250. The upper end of the assembly part 210-1 is flush with the inner surface of the tub bottom. That is, in this embodiment, the lower end of the support column 210 is also flush with the inner surface of the tub bottom. Since the water-stirring rib 220 is disposed on the support column 210 and 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 tub bottom.

[0167] like Figure 7As shown, in another embodiment, the bottom of the washing tub has a downwardly extending groove-shaped structure 250. The bottom of the washing tub is almost flush with the horizontal plane, and a groove-shaped structure 250 is formed by a downward indentation in the middle area of ​​the bottom. An installation port is provided on the bottom surface of the groove-shaped structure 250, and the agitator shaft of the drive device is inserted through the installation port into the assembly part 210-1, which is vertically arranged in the groove-shaped structure 250, and connected to the water agitator 200. The assembly part 210-1 is vertically arranged and protrudes from the groove-shaped structure 250, higher than the inner surface of the bottom of the tub. The assembly part includes two parts, a first part and a second part, which are connected to each other. The first part is vertically arranged in the groove-shaped structure 250 and connected to the agitator shaft, and the second part protrudes from the inner surface of the bottom of the tub and is connected to the support column 210. In this embodiment, the radius of the groove-shaped structure 250 is slightly larger than the radius of the assembly part. More specifically, the radius of the groove-shaped structure 250 is slightly larger than the radius of the assembly part installed therein, that is, the radius of the first part.

[0168] In other words, in this design, the upper part of the second section of the assembly part is a certain distance from the inner surface of the bottom of the bucket, so the lower end of the water-stirring rib 220 is also a certain distance from the inner surface of the bottom of the bucket.

[0169] In this design, a flexible material 260 is used to cover the outer periphery of the assembly section. Specifically, the flexible material 260 is wrapped around the outer periphery of the portion protruding from the groove structure 250 above the inner surface of the barrel bottom, that is, the flexible material 260 is wrapped around the outer periphery of the second part of the assembly section.

[0170] In the solution provided in this embodiment, the lowest end of the agitator 220 does not directly contact the bottom of the washing tub, but is spaced apart from the inner surface of the tub bottom through the assembly part. Therefore, during use, when the agitator shaft drives the agitator component to rotate, the agitator 220 will not rub against the inner surface of the washing tub bottom, thus not increasing the friction between the agitator component and the bottom of the washing tub when rotating.

[0171] Of course, in other embodiments of this invention, the trough structure 250 may not be provided at the bottom of the washing tub. Instead, an installation opening may be directly provided on the surface of the tub bottom, with the assembly part protruding directly from the inner surface of the tub bottom. In other words, the lower end of the support rib is a certain distance from the inner surface.

[0172] In the above design, the lowest point of the agitator 220 does not directly contact the bottom of the washing tub 100, but is spaced apart from the inner surface of the tub bottom. Therefore, during use, when the agitator shaft drives the agitator 200 to rotate, the agitator 220 will not rub against the inner surface of the tub bottom of the washing tub 100, thus not increasing the friction between the agitator 200 and the tub bottom when rotating. Furthermore, it avoids the existence of cleaning dead zones between the agitator 220 and the tub bottom.

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

[0174] The opposite sides of any two adjacent water-stirring ribs are wrapped with flexible material 260;

[0175] The outer edges of several agitator 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 this circle perpendicularly to the bottom of the tub is directly located on the inner surface of the bottom of the washing tub.

[0176] With the vertical distance between any position on the outer edge of the agitator 220 and the support column 210 as the radius, draw a circle with the axis of the support column parallel to the outer edge as the center. The projection of any position on the circumference of this circle perpendicularly to the bottom of the tub is directly located on the inner surface of the bottom of the washing tub 100.

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

[0178] In this embodiment, the outer edge of the agitator 220 is arc-shaped, and a flexible material 260 is provided on this outer edge. The projection of this outer edge vertically towards the bottom of the tub is directly and unobstructed on the inner surface of the bottom of the washing tub 100. The outer edge of the agitator 220 extends vertically downwards to the bottom of the inner tub from any point, contacting the inner surface of the inner tub bottom. That is, no dial is provided in the straight line area between the location of the projection of the agitator 220's maximum radius edge vertically towards the bottom of the tub and the outer periphery of the support column 210.

[0179] Since the agitation ribs 220 in this embodiment are arranged at intervals along the circumference of the support column 210, the outer edges of several agitation 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 perpendicularly to the bottom of the tub is directly located on the inner surface of the bottom of the washing tub 100.

[0180] Because the water-stirring ribs are plate-shaped structures, the opposite sides of any two adjacent water-stirring ribs are wrapped with flexible material 260.

[0181] In this embodiment, a circle is drawn with the vertical distance between the edge of the stirring rib 220 (where its maximum radius is located) and the support column 210 as the radius, and the center of the support column 210 parallel to the edge of the stirring rib 220's maximum radius as the center. No dial is provided in the annular area formed between the projection of the edge of this circle perpendicularly to the bottom of the bucket and the outer periphery of the support column 210. In this embodiment, there is no bottom disc-shaped stirring section.

[0182] Similarly, the circular area formed by the edge of the maximum radius segment Dmax on the stirring plate 230, where the projection of the edge of the circle perpendicularly onto the bottom of the bucket is located, and the annular area formed between the support column 210 and the outer periphery of the support column 210, is not equipped with a dial.

[0183] The solution in this embodiment also includes: the depth of the washing tub 100 is H, and there is a gap between the maximum radius segment Dmax of the agitator plate 230 of the agitator component 200 and the inner surface of the tub bottom, with a gap height of h. The above-mentioned distance h and the depth H of the washing tub 100 satisfy: h / H≥1%. Through extensive preliminary testing, it has been found that when the distance h and the depth H of the washing tub 100 satisfy the above-mentioned proportional relationship, the effect of preventing dirt and grime from accumulating between the agitator component 200 and the washing tub 100 is the best.

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

[0185] In this design, to ensure sufficient washing space for the clothes, the maximum radius segment Dmax on the agitator 230 cannot be too large. Specifically, the length of the maximum radius segment Dmax can be set to not exceed the radius of the inner drum.

[0186] The solution provided in this embodiment, by setting a water-stirring component 200 in the washing tub 100, not only avoids the accumulation of dirt and grime between the water-stirring component 200 and the bottom of the tub, thus improving the user experience, but also saves energy.

[0187] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
