Washing drum assembly for washing machines, and washing equipment

Abstract

The invention relates to a washing drum assembly for a washing and laundry appliance. This washing drum assembly comprises a washing drum and a water agitator arranged in a rotating manner within the washing drum. The water agitator extends upwards from the bottom of the washing drum. The water agitator has a maximum radius at a certain distance from the bottom of the drum, and this certain distance allows at least the portion of laundry to be washed below the position where the maximum radius of the water agitator is located. According to the invention, the relative rotational movement between the water agitator and the washing drum is used to agitate the laundry and the water flow to wash the laundry in the drum. Since the laundry can be washed below the position where the maximum radius of the water agitator is located and thereby come into contact with the surface of the water agitator facing towards the bottom of the drum, the problem of existing washing appliances in which dirt and residue easily accumulate between the agitator and the bottom of the drum and are difficult to clean is avoided.At the same time, the relative force between the laundry and the agitator can be reduced, thereby reducing the energy consumption of the motor used to drive the agitator.

Description

Washing bucket assembly of washing equipment and washing equipment Technical Field

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

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

[0003] A pulsator washing machine usually contains 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 in the tub. Existing pulsators are usually flat, circular pulsators. During washing, impurities such as dirt and lint on the clothes easily accumulate in the gap between the bottom surface of the pulsator and the tub, and cannot be effectively cleaned by simply flushing. In addition, dirt and lint are prone to breed bacteria when left 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] Agitator-type washing machines have also been proposed in the prior art, using an agitator with a certain size along the axial direction of the washing tub to replace the pulsator in a pulsator washing machine. However, as shown in Figure 1, the agitator 1 in existing agitator-type washing machines is often in an "inverted T" shape, consisting of an axial agitator 2 and a radial agitator 3. The radial agitator 3 is located at the bottom of the washing tub 4 and has a larger radial size. Clothes Y can only be washed in the area above the radial agitator 3 in the tub. This still does not solve the problem that the gap between the agitator 1 and the tub bottom is prone to accumulating dirt and grime, making it difficult to clean. Some other agitator-type washing machines directly install a cylindrical agitator rod on the pulsator at the bottom of the tub. Dirt and bacteria still easily accumulate between the pulsator and the tub bottom.

[0005] On the other hand, for washing machines with a bottom pulsator, a large area of ​​clothing covers the pulsator surface during washing. The friction between the pulsator and the clothing causes the clothing to move in the wash water, which can increase clothing entanglement and wear. Furthermore, the friction between the clothing and the pulsator increases the energy consumption of the drive motor to rotate the pulsator.

[0006] In view of this, the present invention is proposed.

[0007] Summary of the Invention

[0065] The support column and the assembly portion have the same radius at their connection points, and the two are integrally formed.

[0066] Furthermore, the projection of any position at the maximum radius perpendicular to the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel.

[0067] Furthermore, the projection of any position of the outer edge of the water stirring rib vertically toward the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel.

[0068] Furthermore, a circle is drawn with the vertical distance between any position of the outer edge of the water stirring rib and the support column as the radius and the axis of the support column parallel to the outer edge as the center. 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.

[0070] The water stirring tray has an extended height in the direction of the central axis of the washing tub, and the maximum radius is located at any extended height position of the water stirring tray.

[0071] Furthermore, the water stirring ribs first extend obliquely toward the edge of the washing tub opening, and then extend upwards toward the tub opening in a direction parallel to the support column.

[0072] The length of the largest section does not exceed the radius of the washing tub.

[0073] Furthermore, the washing tub includes a tub body and a tub bottom, and the maximum radius of the water stirring member is arranged higher than the highest point of the tub bottom.

[0074] A sixth aspect of the present invention provides a washing device, comprising the washing tub assembly of the washing device provided above.

[0075] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0076] 1. The maximum radius of the water-stirring member is set at a certain distance from the bottom of the washing tub, so that the clothes can be washed below the maximum radius of the water-stirring member, and the surface of the water-stirring member below the maximum radius can contact the clothes in the tub, and the friction between the clothes and the surface of the water-stirring member is used to prevent lint or other dirt from adhering to the surface of the water-stirring member.

[0077] 2. The assembly portion of the water-stirring member arranged near the bottom of the washing tub is not the point where the radius of the water-stirring member is the largest, thereby avoiding the water-stirring member having a large radius in the area close to the bottom of the tub, which is beneficial for exposing most of the bottom of the tub to the space where clothes can be in contact. In addition, the contact and friction between the clothes and the bottom of the tub during the washing process can be used to prevent the adhesion of lint and other dirt, thereby avoiding the problem of dirt and grime easily accumulating between the stirring device and the bottom of the tub of existing washing equipment and being difficult to clean.

[0078] 3. The radius of the bottom end face of the water-stirring component is small enough to achieve a connection between the water-stirring component and the bottom of the barrel without an impeller, so that most of the area of ​​the bottom of the barrel is exposed to form a washing surface in contact with the clothes, which can avoid the problem that dirt and grime are easily hidden between the stirring device and the bottom of the barrel of existing washing equipment and are difficult to clean; since clothes can be washed below the maximum radius of the water-stirring component without covering a large area on the water-stirring component, it can also reduce entanglement and wear on clothes and reduce the energy consumption of the motor used to drive the water-stirring component.

[0079] 4. A first guiding surface is formed at the largest radius of the water-stirring member. While preventing lint or other dirt from adhering to the outer surface of the water-stirring member, the clothes can move outward along the first guiding surface, thereby enhancing the effect of the water-stirring member rotating to drive the clothes to move outward and flip during the washing process, thereby improving the washing effect and preventing the clothes from gathering in the center and getting entangled.

[0080] 5. There is a gap between the maximum radius of the water-stirring component and the bottom of the barrel for washing clothes, and the height of the gap is greater than the preset value, so that water can flow into the gap to flush away stains, avoiding the accumulation of dirt between the water-stirring component and the bottom of the barrel. This solution improves the user experience.

[0110] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0111] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0112] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. 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.

[0113] 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.

[0114] As shown in Figures 2 to 25, embodiments of the present invention provide a washing tub assembly for a washing machine, and a washing machine having the washing tub assembly. The washing machine may be a washing machine, a washer-dryer, a care machine, or other washing machine having a laundry washing function.

[0115] Specifically, the washing tub assembly includes a washing tub 100 and a water stirring member 200 rotatably disposed inside the washing tub 100. The washing device further includes a driving device, which is transmission-connected to the washing tub 100 and the water stirring member 200, respectively.

[0116] More specifically, the output shaft of the drive device is connected to the agitator shaft 300 and the dehydration shaft 110. The agitator shaft 300 is connected to and fixed relative to the water agitation member 200, driving the rotation of the water agitation member 200. The dehydration shaft 110 is fixed to the bottom 100-3 of the washing tub 100, driving the rotation of the washing tub 100.

[0117] During the washing process, the driving device drives the water-stirring member 200 to rotate independently, or drives the water-stirring member 200 and the washing tub 100 to rotate in opposite directions, thereby utilizing the relative rotational tendency between the water-stirring member 200 and the washing tub 100 to agitate the clothes C and the wash water in the tub, thereby cleaning the clothes C. During the dehydration process, the driving device drives the water-stirring member 200 and the washing tub 100 to rotate synchronously at high speed, utilizing centrifugal force to spin dry the clothes C in the tub.

[0118] However, if the narrow gap between the agitating member 200 and the washing tub 100 exists, the lint and dirt that falls off during the washing process can easily become lodged in the wash water. This makes it difficult for the agitating member 200 to be removed by the impact of the water flow during the washing process, requiring the user to manually disassemble the agitating member 200 for cleaning. If the user fails to clean the gap for a long time, a large amount of dirt can accumulate in the gap between the agitating member 200 and the washing tub 100, easily breeding bacteria and causing secondary contamination of the clothes C.

[0119] Example 1

[0120] As shown in Figures 2 and 3, this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly, which is used to solve the problem that there is a dead corner between the water stirring member 200 and the washing tub 100 where dirt and grime are hidden and difficult to clean.

[0121] Specifically, the washing tub assembly of this embodiment includes a washing tub 100 and a water-stirring member 200 rotatably disposed within the washing tub 100. The water-stirring member 200 includes a mounting portion 210-1 extending along the axial direction of the washing tub 100 and a water-stirring portion 240 connected to the mounting portion 210-1. The mounting portion 210-1 is located between the bottom surface of the washing tub 100 and the water-stirring portion 240 of the water-stirring member 200. The radial dimension of the mounting portion 210-1 along the radial direction of the washing tub 100 is smaller than the maximum radial dimension of the water-stirring member 200. Furthermore, the bottom of the water-stirring member 200 does not have a disc-shaped stirring portion.

[0122] In the above embodiment, mounting portion 210-1 is provided at the bottom of water-stirring member 200 for connection to stirring shaft 300. During washing, water-stirring member 200 rotates relative to washing tub 100, stirring the wash water and clothing within the tub using stirring portion 240. Mounting portion 210-1 does not constitute the maximum radius of water-stirring member 200, and the bottom of water-stirring member 200 lacks a disc-shaped stirring portion. In other words, water-stirring member 200 does not extend radially across tub bottom 100-3 at the bottom of washing tub 100, leaving a substantial portion of tub bottom 100-3 exposed within the washing space.

[0123] In the embodiments of the present invention, the washing space is defined as the area accessible to clothing during the washing process. Therefore, with the above-described structure, the majority of the tub bottom 100-3 is in contact with clothing during the washing process, preventing dirt from adhering. This avoids the problem of dirt easily accumulating between the stirring device and the tub bottom in conventional washing equipment, making it difficult to clean.

[0124] Furthermore, in the specific embodiment of this embodiment, the radius of the mounting portion 210-1 along the radial direction of the washing tub 100 is less than or equal to the radius of any horizontal cross-section of the water-stirring portion 240 near the mounting portion 210-1. In other words, within a certain height range upward from the lower end of the water-stirring member 200, the mounting portion 210-1 has the smallest radius within that range.

[0125] In this embodiment, the radius of the mounting portion 210-1 is set sufficiently small, and the radius increases above the mounting portion 210-1, that is, in the area where the water stirring portion 240 is close to the mounting portion 210-1. This is equivalent to the water stirring member 200 being provided with a slightly larger radial structure at a certain height above the barrel bottom 100-3. In other words, the water stirring member 200 of this embodiment does not have a radially extending wave plate structure at its bottom.

[0126] Compared to conventional pulsator washing machines or agitator washing machines with radial agitators, installing the water-stirring member 200 of this embodiment in the washing tub 100 allows the tub bottom 100-3 to be almost completely exposed within the washing space. This prevents dirt from adhering to the tub bottom 100-3 by utilizing the contact and friction between the clothing C and the tub bottom 100-3. This effectively prevents dirt accumulation, avoids secondary contamination of clothing caused by dirt accumulation, and improves the user experience.

[0127] It should be noted that, in the embodiment of the present invention, the radius dimension of the horizontal cross section of the water stirring portion 240 refers to the distance from the farthest point from the rotation center to the rotation center on the horizontal cross section of the water stirring portion 240 taken along the horizontal direction (see Figure 4).

[0128] Specifically, if the horizontal cross-section of the agitating portion 240 is circular as shown in Figure 5 , 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 6 to 11 , 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).

[0129] Accordingly, in this embodiment and subsequent embodiments, the “diameter” mentioned refers to twice the radius size mentioned above.

[0130] In a further embodiment of this embodiment, the water stirring portion 240 has a horizontal cross-section with a maximum radius at a certain height above the upper end of the mounting portion 210-1, namely, the maximum radius Rmax shown in Figures 2 and 3. The radius at this point is also the maximum radius of the water stirring member 200. A washing space is formed between the height of the maximum radius Rmax and the bottom 100-3 of the washing tub 100. The area of ​​the water stirring portion 240 below the maximum radius Rmax serves as a first clothing contact surface capable of contacting the clothing C during washing.

[0131] As a specific embodiment, in this embodiment, the distance h between the maximum radius Rmax of the water stirring member 240 and the tub bottom 100-3 is greater than 10 cm, thereby ensuring that the clothes C can be washed in the washing space at a height lower than the maximum radius Rmax. This ensures that the clothes C are fully in contact with the tub bottom 100-3 and the surface of the water stirring member 240 below the maximum radius Rmax, preventing dirt from accumulating between the water stirring member 200 and the tub 100.

[0132] In a further solution of this embodiment, there is also a certain distance in height between the maximum radius Rmax of the water stirring part 240 and the barrel mouth of the washing barrel 100, so that the washing water level can be higher than the maximum radius Rmax of the water stirring part 240, so that the clothes C can be washed above the position of the maximum radius Rmax of the water stirring part 240.

[0133] In the above solution, the washing tub 100 can accommodate clothes C for washing both above and below the water stirring portion 240 at the maximum radius Rmax. In this way, the outer surface of the water stirring portion 240 can basically contact the washed clothes C and generate friction with the clothes C. By increasing the surface area in contact with the clothes C, the washing effect can be enhanced.

[0134] Furthermore, in this embodiment, the water stirring portion 240 includes a support column 210 extending axially from the upper end of the mounting portion 210-1, and a water stirring structure disposed on the sidewall of the support column 210. Because a washing space is formed within the washing tub 100 in an area below the maximum radius Rmax of the water stirring portion 240, the water stirring structure is disposed at least in the area below the maximum radius Rmax.

[0135] In one specific embodiment, the water stirring structure includes a water stirring rib 220 protruding from the sidewall of the support column 210 and extending axially. The protrusion direction of the water stirring rib 220 on the sidewall of the support column 210 coincides with the radial direction of the washing tub 100, or forms an angle less than 90° with the radial direction of the washing tub 100. This ensures that when the water stirring rib 220 rotates with the water stirring member 200, the surface of the water stirring rib 220 is positioned opposite the direction of rotation, effectively stirring the water.

[0136] More specifically, a plurality of agitating ribs 220 are circumferentially spaced apart on the sidewall of the support column 210. The agitating ribs 220 are preferably symmetrically arranged about the rotation axis. Clothes C can be washed in the area between two adjacent agitating ribs 220, thereby contacting both sides of the agitating ribs 220 and the area between the two agitating ribs 220 on the sidewall of the support column 210. This avoids any blind spots on the sidewall of the support column 210 where dirt can easily accumulate.

[0137] The water-stirring component 200 having the above-mentioned structure has a side surface of the water-stirring portion 240 including both the side wall of the support column 210 and the surface of the water-stirring rib 220 that is farthest from the rotation axis, and the radius of the water-stirring portion 240 is the distance between the farthest surface from the rotation axis on the water-stirring rib 220 and the rotation axis.

[0138] 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. For structures where the sidewalls of the support column 210 are provided with raised stirring ribs 220, 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.

[0139] 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.

[0140] In this embodiment, the side of the water stirring portion 240 is configured such that as the height of the rotation axis increases, the distance between the side of the water stirring portion 240 and the wall of the washing tub 100 remains constant or changes gradually or stepwise.

[0141] As a specific embodiment, as shown in Figure 2 and Figures 12 to 14, the water stirring portion 240 has a unique maximum radius Rmax in the height direction, and at least below the maximum radius Rmax, as the height increases, the distance between the side of the water stirring portion 240 and the barrel wall of the washing barrel 100 decreases as the height increases, that is, the horizontal cross-sectional radius of the water stirring portion 240 increases upward along the axis.

[0142] In a first specific solution, as shown in FIG12 , the maximum radius Rmax of the agitating portion 240 is set at the top of the agitating member 200 , that is, the top surface of the agitating member 200 is the horizontal section of the agitating portion 240 having the maximum radius.

[0143] In a second embodiment, as shown in FIG2 , the maximum radius Rmax of the agitating portion 240 is close to the top of the agitating member 200, but is a certain distance away from the top of the agitating member 200. Specifically, the upper surface of the agitating portion 240 at the maximum radius Rmax is an upwardly convex curved surface, the highest point of which forms the top of the agitating member 200.

[0144] As a detailed solution, a plurality of water-stirring ribs 220 are disposed on the side of the support column 210. The radial dimensions of the water-stirring ribs 220 gradually increase from bottom to top, forming the maximum radius Rmax of the water-stirring portion 240 at the top. A water-stirring disc 230 is disposed at the top end of the support column 210, perpendicular to the axis. The top surface of the water-stirring disc 230 is an upwardly convex curved surface.

[0145] In the third specific solution, as shown in FIG. 13 and FIG. 14 , the maximum radius Rmax of the water stirring portion 240 is located in the middle of the water stirring portion 240 along the height direction.

[0146] In one detailed embodiment, as shown in Figure 13 , the distance between the side of the water stirring portion 240 and the wall of the washing tub 100 continuously changes in height. Specifically, as the height increases, the horizontal cross-sectional radius of the water stirring portion 240 gradually increases from the bottom 100-3 of the washing tub 100 upward, until it reaches the maximum radius Rmax. Above the maximum radius Rmax, the side of the water stirring portion 240 extends upward and gradually approaches the axis, causing the horizontal cross-sectional radius of the water stirring portion 240 to gradually decrease, ultimately forming the top of the water stirring member 200.

[0147] In another detailed embodiment, as shown in Figure 14, the distance between the side of the water stirring member 240 and the wall of the washing tub 100 has a sudden change at at least one height. Specifically, as the height increases, the horizontal cross-sectional radius of the water stirring member 240 first gradually increases from the bottom 100-3 of the washing tub 100 upward, and at a certain height, the radius suddenly increases, forming the maximum radius Rmax. The horizontal cross-sectional radius of the water stirring member 200 then remains constant within a certain height range before suddenly decreasing. The side of the water stirring member 240 then extends upward and approaches the axis, causing the horizontal cross-sectional radius of the water stirring member 240 to gradually decrease, ultimately forming the top of the water stirring member 200. In this embodiment, the distance h from the maximum radius Rmax to the bottom 100-3 of the washing tub 100 refers to the distance from the lowest height within the height range where the horizontal cross-sectional radius of the water stirring member 240 remains constant to the bottom 100-3 of the washing tub 100.

[0148] In the above scheme, Figures 13 and 14 show the outer contour of the water stirring portion 240 of the water stirring member 200. Taking the structure shown in Figure 14 as an example, a specific scheme of the structure is to set a water stirring rib extending from the lower end to the upper end on the support column, and the side of the water stirring rib away from the axis extends upward along the outer contour of the water stirring portion 240 in the figure, that is, it first tilts toward the periphery, then extends horizontally outward, then extends vertically, then extends horizontally inward, and finally extends obliquely toward the axis. Another specific scheme of the structure can be to set a disc-shaped water stirring structure perpendicular to the support column and having a certain thickness in the middle of the support column to form the maximum radius Rmax, and on the upper and lower sides of the maximum radius Rmax, water stirring ribs extending along the axial direction are respectively set on the side walls of the support column.

[0149] It should be understood that the above-mentioned structure is only used for illustration and is not intended to limit the present invention.

[0150] As another specific embodiment, as shown in Figure 15, the water stirring portion 240 has a unique maximum radius Rmax in the height direction, but below the maximum radius Rmax, as the height increases, the distance between the side of the water stirring portion 240 and the barrel wall of the washing barrel 100 alternately increases and decreases with the increase in height, that is, the horizontal cross-sectional radius of the water stirring portion 240 alternately increases and decreases upward along the axis.

[0151] In detail, between the maximum radius Rmax of the water stirring part 240 and the lower end of the water stirring part 240, one or more radially protruding structures are provided. Along the axial direction upward, the horizontal cross-sectional radius of the water stirring part 240 first gradually increases to the lowest protruding structure, then gradually decreases, and then gradually increases to the next protruding structure. After passing the protruding structure, it gradually decreases and then gradually increases until it finally increases to the maximum radius Rmax of the water stirring part 240.

[0152] It is understandable that the above-mentioned protruding structure can be formed by the outer contour of the water-stirring rib itself, or can be formed by a plurality of disc-shaped water-stirring structures arranged perpendicular to the support column.

[0153] As another specific embodiment, as shown in FIG16 , the water stirring portion 240 has a plurality of maximum radii Rmax spaced apart along the axis of the washing tub 100. Specifically, as the height increases, the horizontal cross-sectional radius of the water stirring portion 240 alternately increases and decreases, each time increasing to the same radius and then decreasing, thereby forming a plurality of spaced-apart maximum radii Rmax spaced apart.

[0154] In the above solution, between two adjacent maximum radius points Rmax, the side surface of the water stirring portion 240 extends upward, first tilts toward the axis, and then tilts toward the periphery.

[0155] In a further embodiment of the present invention, the distance between the maximum radius Rmax of the water stirring portion 240 and the upper end of the mounting portion 210-1 is greater than the axial extension of the mounting portion 210-1 along the washing tub 100. Preferably, the distance between the maximum radius Rmax of the water stirring portion 240 and the upper end of the mounting portion 210-1 is several to ten times the axial extension of the mounting portion 210-1 along the washing tub 100.

[0156] In this way, the washing space formed below the maximum radius Rmax of the water stirring part 240 is ensured to be large enough, so that the clothes can fully contact the side of the water stirring part 240 and the bottom 100-3 of the washing tub 100 in the washing space to prevent dirt from adhering.

[0157] In this embodiment, the washing tub 100 has a mounting portion at the center of the bottom 100-3 for mounting the agitator shaft 300. The agitator shaft 300 rotatably passes through the mounting portion and is connected to the mounting portion 210-1 of the water-stirring member 200. The mounting portion 210-1 is located above the mounting portion and has a radius equal to or substantially equal to the radius of the mounting portion.

[0158] With this structure, the projection area formed by the mounting portion 210-1 onto the bottom 100-3 of the washing tub 100 substantially overlaps with the area occupied by the mounting portion. The area on the bottom 100-3 surface outside this projection area constitutes the second clothing contact surface within the washing space defined between the maximum radius Rmax and the bottom 100-3. This second clothing contact surface can contact clothing during the washing process. This substantial overlap between the projection area and the area occupied by the mounting portion maximizes the area of ​​the second clothing contact surface, thereby minimizing the accumulation of dirt on the bottom 100-3 of the washing tub 100.

[0159] As a specific embodiment, the second clothing contact surface occupies 90% or more of the total area of ​​the barrel bottom 100 - 3 of the washing tub 100 , and preferably 95% or more of the total area of ​​the barrel bottom 100 - 3 of the washing tub 100 .

[0160] In a further solution of this embodiment, the water-stirring rib 220 provided on the side wall of the support column 210 has its lower end spaced apart from the bottom 100-3 of the washing tub 100, thereby preventing a dead angle that cannot contact clothes from being formed between the lower end of the water-stirring rib 220 and the bottom 100-3.

[0161] Preferably, the water stirring portion 240 further includes a water stirring pan 230 disposed at the upper end of the support column 210. The outer periphery of the water stirring pan 230 defines the maximum radius Rmax of the water stirring portion 240. The water stirring ribs 220 extend upward to the underside of the water stirring pan 230 to prevent the formation of a dead corner between the water stirring ribs 220 and the water stirring pan 230, which is inaccessible to the clothing C and easily harbors dirt.

[0162] Preferably, a smoothly curved transition surface is provided between the upper end of the sidewall of the support column 210 and the lower surface of the water-stirring pan 230. Similarly, rounded corners are provided between the two side surfaces of the water-stirring rib 220 and the lower surface of the water-stirring pan 230. This further reduces the number of hard-to-clean corners on the water-stirring member 200.

[0163] As a specific solution, as shown in Figure 2, the side wall of the support column 210 extends in the vertical direction or close to the vertical direction, and the radial size of the water-stirring rib 220 along the washing tub 100 increases with increasing height. The upper end of the water-stirring rib 220 is away from the side of the support column 210 and coincides with the outer periphery of the water-stirring plate 230, so that the radial size of the water-stirring rib 220 along the washing tub 100 is maximized as much as possible, which can enhance the stirring force of the washing water and enhance the washing effect.

[0164] In a preferred embodiment, the radial dimension of the lower end of the agitating rib 220 is approximately zero, and the side of the agitating rib 220 away from the axis extends obliquely upward toward the periphery at the lower end region. This ensures that the lower end surface of the agitating rib 220 does not directly face the bottom 100-3 of the washing tub 100, or the area of ​​the lower end surface is sufficiently small that the flow of wash water sufficiently prevents dirt from accumulating there, thereby avoiding the formation of a cleaning dead corner where dirt easily accumulates.

[0165] In the preferred embodiment, at the lower end of the water-stirring rib 220, the acute angle α between the side away from the axis and the horizontal direction is greater than 20°, preferably greater than 30°, to ensure that the lower area of ​​the water-stirring rib 220 can contact the clothes.

[0166] In a further embodiment, the side of the agitating rib 220 away from the axis forms a curved surface. Specifically, in this embodiment, the side of the agitating rib 220 away from the axis extends upward at a certain angle to the horizontal. In the lower region, the acute angle with the horizontal increases with increasing height, forming a curved surface that curves away from the axis. After extending beyond a certain height, the acute angle with the horizontal decreases with increasing height, forming a curved surface that curves toward the axis and ultimately extends to the periphery of the agitating tray 230.

[0167] In this embodiment, the outer periphery of the water-stirring ribs 220 is a curved surface extending upward. During washing, the rotation of the water-stirring member 220 causes the wash water to flow along this curved surface, thereby lifting the clothes near the center of the tub bottom 100-3. After the clothes rise with the water to a point close to the maximum radius Rmax, they are guided toward the periphery. This enhances the tumbling movement of the clothes within the tub, improving the washing effect while preventing the clothes from excessively converging toward the center and causing entanglement.

[0168] In a further embodiment, the height of the maximum radius Rmax of the agitating portion 240 of the agitating member 200 in this embodiment is positioned between the highest and lowest water levels of the washing machine. Thus, when washing at different water levels, the relative rotation of the agitating member 200 and the washing tub 100 can generate different water flow patterns to move the clothes C for washing. In particular, below the maximum radius Rmax, the clothes C are washed along a circular path.

[0169] The circular path mentioned above means that the clothes move toward the center in the bottom area of ​​the washing tub 100, are lifted by the water stirring member 200 to a position close to the maximum radius Rmax of the water stirring portion 240, move toward the periphery, and then fall.

[0170] 17 and 18 , as a specific solution, the circular path of the movement of the clothes below the maximum radius Rmax of the water stirring part 240 during washing includes: the clothes move toward the central area along the bottom 100-3 of the washing tub 100, move upward along the side of the water stirring part 240 in the central area to below the maximum radius Rmax and then move toward the periphery, and move downward in the area close to the wall of the washing tub 100.

[0171] More specifically, the washing tub assembly of this embodiment is applied to a washing device, as shown in FIG17 . When operating at a low water level W1 lower than the maximum radius Rmax of the water stirring portion 240 , the clothes move in the water along the circular path described above.

[0172] Specifically, during the washing process, the water-stirring member 200 and the washing tub 100 rotate relative to each other, causing the clothing to move along the path indicated by the arrow in the figure, within the space below the maximum radius Rmax of the water-stirring portion 240. Specifically, the clothing moves along the bottom 100-3 of the washing tub 100 toward the center, where it is collected. From there, the clothing is lifted along the sidewalls of the support column 210 or the outer edges of the water-stirring ribs 220 to below the maximum radius Rmax. The clothing then moves toward the periphery, ultimately falling along the walls of the washing tub 100 to the bottom 100-3, forming a circular motion.

[0173] As shown in Figure 18, when operating at a high water level W2 that is higher than the maximum radius Rmax of the stirring part 240, in the area below the maximum radius Rmax of the stirring part 240, the clothes move along the above-mentioned circular path in the water; and in the area above the maximum radius Rmax of the stirring part 240, the clothes move close to the circumferential direction of the washing tub 100.

[0174] Specifically, during the washing process, the agitating member 200 and the washing tub 100 rotate relative to each other. Within the area below the maximum radius Rmax of the agitating portion 240, the clothing's movement path is essentially the same as that observed at the low water level W1. Above the maximum radius Rmax of the agitating portion 240, the clothing moves alternately forward and reverse along the circumference of the washing tub 100, following the alternating forward and reverse rotation of the agitating member 200.

[0175] In the above solution, when using different wash water levels, the water stirring member 200 can move the clothes in the tub in different ways for washing, providing more diverse washing options. Furthermore, in the area below the maximum radius Rmax of the water stirring member 240, the clothes move along a circular path, which not only enhances the tumbling of the clothes and improves the washing effect, but also avoids the problem of clothes tending to converge toward the center and causing entanglement in existing pulsator washing machines.

[0176] In this embodiment, the assembly relationship between the water stirring member 200, the stirring shaft 300 and the washing tub 100 can adopt the following embodiments.

[0177] In a first embodiment, a groove structure with an open top is provided on the bottom 100-3 of the washing tub 100 as the mounting portion. The stirring shaft 300 extends into the inner side of the washing tub 100 through a mounting through-hole provided on the bottom wall of the groove structure. The assembly portion 210-1 is rotatably plugged into the groove structure. Because the lower end of the water-stirring rib 220 is not lower than the upper end of the assembly portion 210-1, the lower end surface of the water-stirring rib 220 can contact the clothing. At the same time, because there are no other structures extending radially along the washing tub 100 between the lower end of the water-stirring rib 220 and the assembly portion 210-1, the area of ​​the bottom 100-3 of the washing tub 100 located outside the groove structure can contact the clothing during washing, preventing the adhesion of lint and dirt.

[0178] In a second embodiment, a gap exists between the lower end surface of the mounting portion 210-1 and the bottom 100-3 of the washing tub. The mounting portion at the center of the bottom 100-3 serves as a through-hole. The agitator shaft 300 passes through the through-hole in the bottom 100-3 of the washing tub 100 and connects to the mounting portion 210-1. The gap between the lower end surface of the mounting portion 210-1 and the bottom 100-3 allows both the lower end surface of the mounting portion 210-1 and the area surrounding the through-hole on the bottom 100-3 of the washing tub 100 to contact clothing, preventing the formation of blind spots where dirt can easily accumulate.

[0179] In a third embodiment, the mounting portion at the center of the bottom 100-3 is also a through-hole. The agitator shaft 300 extends through the through-hole in the bottom 100-3 of the washing tub 100 and into the interior of the washing tub 100. The mounting portion 210-1 is mounted on the upper end of the agitator shaft 300, with little or no clearance between the lowermost end of the mounting portion 210-1 and the bottom 100-3 of the washing tub 100. The difference between the outer diameter and inner diameter of the bottom of the mounting portion 210-1 is sufficiently small that the outer surface of the mounting portion 210-1 can contact the clothes during the washing process, and the area of ​​the bottom 100-3 of the washing tub 100 located outside the through-hole can contact the clothes, preventing the formation of cleaning dead corners where dirt easily accumulates. Preferably, the outer wall of the mounting portion 210-1 and the sidewall of the agitator shaft 300 have a smooth transition, further avoiding the possibility of cleaning dead corners.

[0180] When washing clothes C, the washing device having the washing tub assembly described in this embodiment can drive the clothes C to move along a circular path below the maximum radius Rmax of the water stirring part 240 of the water stirring member 200 by controlling the relative rotation between the water stirring member 200 and the washing tub 100 for washing.

[0181] Specifically, at the bottom of the washing tub 100, the stirring action of the water flow by the water stirring member 200 creates a radial flow pattern within the washing tub 100, thereby driving the clothing C along the bottom 100-3 of the washing tub 100 toward the center. The clothing C, gathering toward the center, moves to the area where it contacts the mounting portion 210-1 of the water stirring member 200. The rotation of the water stirring member 200 lifts the clothing C upward until it reaches below the maximum radius Rmax of the water stirring portion 240. Below the maximum radius Rmax of the water stirring portion 240, the upward movement of the water flow and clothing C is blocked. The water flow and clothing C then move along the bottom Rmax of the water stirring portion 240 toward the outer tub wall, ultimately descending along the tub wall back to the bottom 100-3 under the influence of gravity and the water flow.

[0182] In this embodiment, the water-stirring member 200 installed in the washing tub 100 is an assembly portion 210-1 with a smaller radius at the portion close to the bottom 100-3 of the washing tub 100, and the radius of the water-stirring member 200 is further increased above the assembly portion 210-1, thereby avoiding the water-stirring member having a larger radius in the area close to the bottom 100-3. In combination with setting the maximum radius Rmax of the water-stirring portion 240 at a certain height above the upper end of the assembly portion 210-1, most of the area of ​​the bottom 100-3 and the area on the side of the water-stirring portion 240 below the maximum radius Rmax are exposed to the space where clothes can be in contact. In addition, the contact and friction between the clothes and the bottom 100-3 and the surface of the water-stirring member 200 during the washing process can be used to prevent the adhesion of lint and other dirt, thereby avoiding the problem that dirt and grime are easily hidden between the stirring device and the bottom of the tub of the existing washing equipment and are difficult to clean.

[0183] On the other hand, during the washing process, the water-stirring component 200 can drive the clothes C to gather towards the center at the bottom of the barrel 100-3, then be lifted to a certain height, and then guide the clothes C to move toward the periphery and then fall, thereby moving along a circular path around the water-stirring component 200, which can not only enhance the washing effect, but also prevent the clothes C from getting entangled.

[0184] Example 2

[0185] As shown in FIG. 19 to FIG. 22 , this embodiment further provides a washing tub assembly and a washing device including the washing tub assembly based on the above-mentioned embodiment 1.

[0186] Specifically, in this embodiment, the water stirring portion 240 of the water stirring component 200 includes a support column 210 extending upward from the top of the assembly portion 210-1, a water stirring rib 220 protruding radially or nearly radially on the side wall of the support column 210, and a water stirring plate 230 arranged at the top of the support column 210.

[0187] As a specific embodiment, the top surface of the water stirring tray 230 is an upwardly convex curved surface. In a preferred embodiment, a convex stirring portion 231 is provided on the curved surface for rubbing against the clothes above and stirring the washing water when washing at a higher water level, thereby enhancing the washing effect.

[0188] In this embodiment, the maximum radius Rmax of the water stirring portion 240 is also formed by the outer periphery of the water stirring plate 230. However, unlike the first embodiment described above, in this embodiment, the radial dimension of the support column 210 increases with increasing height, thereby forming a guide surface for guiding the movement of clothes during washing.

[0189] Specifically, in this embodiment, the support column 210 extends from bottom to top and includes a first extension section 211 and a second extension section 212. The sidewalls of the first extension section 211 extend upward from the bottom 100-3 of the washing tub 100, gradually approaching the tub wall of the washing tub 100. The sidewalls of the second extension section 212 extend from the upper end of the first extension section 211 toward the periphery and tilt upward, ultimately extending to the height of the maximum radius Rmax of the water stirring portion 240, that is, to the lower surface of the water stirring tray 230. This allows clothes to be washed below the sidewalls of the second extension section 212 and move toward the periphery along the sidewalls of the second extension section 212.

[0190] More specifically, the sidewalls of the first extension section 211 extend in a straight line and are inclined outward at a slight angle relative to the vertical direction. The sidewalls of the second extension section 212 are inclined at a greater angle relative to the vertical direction than the sidewalls of the first extension section 211. Furthermore, as the height increases, the angle of inclination of the sidewalls of the second extension section 212 relative to the vertical direction gradually increases, forming a curved surface that bends toward the axis.

[0191] As a specific embodiment, the upper end of the second extension section 212 is connected to the lower surface of the water stirring tray 230. The support column 210 of the water stirring member 200 has the above-mentioned structure, which effectively reduces the problem of a cleaning dead corner between the upper end of the support column 210 and the lower surface of the water stirring tray 230 where clothes cannot reach.

[0192] In a detailed solution, the upper end of the side wall of the second extension section 212 coincides with the outer periphery of the water stirring tray 230 , so that the lower surface of the water stirring tray 230 is completely covered by the upper end surface of the support column 210 .

[0193] Furthermore, in this embodiment, the guide surface includes a first guide surface 213 formed by the side wall of the second extension section 212, which is used to guide the clothes rising from the center area of ​​the washing tub 100 to the bottom of the center area to move toward the periphery along the first guide surface 213 during washing. The guide surface also includes a second guide surface 214 formed by the side wall of the first extension section 211, which is used to guide the clothes rising along the second guide surface 214 to the first guide surface 213 during washing.

[0194] Specifically, during washing, the washing machine using the washing tub assembly described in this embodiment rotates the water agitating member 200 relative to the washing tub 100, causing the laundry to move along the bottom 100-3 of the washing tub 100 toward the center, then upward along the first guide surface 213 to the second guide surface 214. Guided by the second guide surface 214, the laundry moves toward the periphery before falling near the wall of the washing tub 100, forming a circular path. This enhances the tumbling of the laundry within the tub, thereby improving the washing effect, while also reducing the likelihood of the laundry converging toward the center and becoming tangled.

[0195] As a specific implementation of this embodiment, at the connecting position of the first extension section 211 and the second extension section 212, the angle between the side walls of the two and the vertical direction is the same. In other words, the first guide surface 213 and the second guide surface 214 have the same inclination angle at the connecting position, achieving a smooth transition connection.

[0196] In another specific embodiment, the inclination angle of the sidewall of the second extension section 212 at the lower end relative to the vertical direction is slightly higher than the inclination angle of the sidewall of the first extension section 211 relative to the vertical direction, thereby forming an angle less than but close to 180° at the junction of the first guide surface 213 and the second guide surface 214. This provides a certain cushioning effect on the clothing as it moves upward along the second guide surface 214 to the first guide surface 213, enhancing the tendency of the clothing to roll toward the periphery.

[0197] In a further embodiment of this embodiment, the agitating ribs 220 extend a certain length along the axial direction of the washing tub 100, extending from the sidewall of the first extension section 211 to the sidewall of the second extension section 212. A plurality of agitating ribs 220 are spaced apart circumferentially around the support column 210, and the angle between adjacent agitating ribs 220 allows laundry to be washed in the area between the adjacent agitating ribs 220 while allowing the laundry to contact the sidewall of the first extension section 211, thereby moving upward along the sidewall of the first extension section 211, i.e., the second guide surface 214.

[0198] In this way, the area of ​​the side walls of the first extension section 211 and the second extension section 212 located between two adjacent water-stirring ribs 220 can come into contact with the clothes, and no dead corner where dirt is easily accumulated is generated.

[0199] Furthermore, in this embodiment, the radial dimension of the water-stirring rib 220 along the washing tub 100 first increases and then decreases from the lower end to the upper end.

[0200] In one specific embodiment, the cross-section of the water-stirring rib 220 parallel to the radial direction of the washing tub 100 is approximately fusiform. The outer edge of the water-stirring rib 220 extends from bottom to top, with the acute angle between the extension direction and the vertical direction gradually decreasing, so that the outer edge of the water-stirring member 200 forms a curved surface that bends toward the wall of the washing tub 100. The upper end of the outer edge of the water-stirring rib 220 coincides with the outer periphery of the water-stirring tray 230.

[0201] The aforementioned structure of the agitating ribs 220 creates a Coanda effect during washing, driving water along the outer edges of the agitating ribs 220. This results in the water flowing along 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 flows more upwards rather than outwards. This enhances the lifting force of the water flow on the clothes near the axis, driving the clothes upwards to the first guide surface 213, ultimately forming a circular path.

[0202] It can be understood that the clothes moving along the bottom 100-3 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 Rmax of the water-stirring part 240, they move toward the periphery under the action of inertia and centrifugal force, and finally fall along the wall of the washing barrel 100 to the bottom 100-3 of the barrel.

[0203] As a preferred embodiment, in order to ensure that there is no cleaning dead corner between the lower end of the water-stirring rib 220 and the bottom 100-3 of the washing bucket 100, the side of the water-stirring rib 220 away from the axis (that is, the peripheral edge surface of the water-stirring rib 220) at least extends obliquely upward toward the periphery in the lower end area. At the lower end position of the water-stirring rib 220, the acute angle α between the extension direction of the peripheral edge surface of the water-stirring rib 220 and the horizontal direction is not less than 20°, and preferably not less than 30°.

[0204] By setting the above-mentioned inclination angle, the clothes can be ensured to contact the lower end of the water stirring rib 220, thus avoiding the formation of a blind spot between the lower end of the water stirring rib 220 and the surface of the bottom 100-3 of the washing tub 100. At the same time, the outer edge of the water stirring rib 220 forms a curved surface that curves toward the wall of the washing tub 100, which helps to create a sufficiently large washing space below the maximum radius Rmax of the water stirring portion 240. This ensures that the surface of the water stirring portion 240 below the maximum radius Rmax can fully contact the clothes, eliminating the blind spot of cleaning.

[0205] As another preferred embodiment, in combination with Figures 19 and 22, the maximum radius Rm of the water stirring portion 240, the radius R0 of the assembly portion 210-1, and the axial height difference h0 between the maximum radius Rmax of the water stirring portion 240 and the upper end of the assembly portion 210-1 satisfy: Rm≤4×R0, and h0≥Rm-R0.

[0206] This proportional relationship ensures that the radial dimension of the agitating member 200 is smaller than its axial dimension. Furthermore, at the bottom of the agitating member 200, near the tub bottom 100-3, the agitating member 200 extends more upward rather than laterally. This allows for a larger angle between the sides of the agitating member 200 and the tub bottom 100-3 of the wash tub 100, effectively exposing the area of ​​the tub bottom 100-3 outside the projection of the mounting portion to the laundry-accessible washing space.

[0207] In a further embodiment of the present invention, the water stirring member 200, the stirring shaft 300 and the tub bottom 100-3 of the washing tub 100 have the following assembly relationship.

[0208] The lowermost mounting portion 210-1 of the agitating member 200 is provided with an open mounting cavity. A mounting portion for the agitator shaft 300 is located at the center of the bottom 100-3 of the washing tub 100. The mounting portion comprises a mounting groove 100-1 recessed from the surface of the bottom 100-3. The mounting portion 210-1 rotatably engages with the mounting groove 100-1. The agitator shaft, which drives the agitating member 200, passes through a mounting hole in the bottom wall of the mounting groove 100-1 and is inserted from its lower end into the mounting cavity of the mounting portion 210-1, where it is secured. The agitator shaft is keyed to the agitator shaft.

[0209] Furthermore, the diameter of the mounting through-hole is consistent with, or slightly smaller than, the radial dimension of the mounting groove 100-1. The projection of the assembly portion 210-1 onto the bottom 100-3 of the washing tub 100 completely overlaps with the area occupied by the mounting groove 100-1 on the bottom 100-3. As a result, the bottom 100-3 of the washing tub 100 outside of the mounting groove 100-1 can contact clothing, effectively preventing dirt from accumulating on the surface of the bottom 100-3 of the washing tub 100.

[0210] The lower end of the water stirring rib 220 is at least flush with the upper end of the assembly portion 210-1, and preferably higher than the upper end of the assembly portion 210-1. A water seal structure 500 can be provided between the assembly portion 210-1 and the installation groove 100-1 to prevent dirt and grime from accumulating inside the installation groove 100-1.

[0211] More preferably, a smoothly transitioned rounded structure is provided at the connection position between the water stirring rib 220 and the support column 210, so that there are almost no cleaning dead corners on the water stirring component 200 where dirt is easily accumulated, thereby ensuring the cleanliness and hygiene inside the washing tub 100 to the greatest extent.

[0212] Further preferably, there is a rounded transition between the outer edge of the water-stirring rib 220 and the two side surfaces of the water-stirring rib 220 to avoid the existence of sharp corner structures that may scratch and damage clothes.

[0213] It will be appreciated that in this embodiment, a certain distance between the lower end surface of the mounting portion and the bottom of the washing tub can be provided, or the difference between the outer and inner diameters of the mounting portion can be sufficiently small, so that the outer surface of the mounting portion (including the outer sidewall and lower end surface) and the area of ​​the washing tub bottom located outside the mounting hole can contact the clothes, thereby preventing the formation of cleaning blind spots. In the above embodiment, the bottom of the washing tub does not need to be provided with a groove structure. Instead, the upper surface of the bottom can be flat, preferably with an upwardly convex area outside the mounting hole.

[0214] In this embodiment, the mounting portion 210-1 at the lower end of the water-stirring member 200 matches the mounting portion, or groove structure, at the center of the bottom 100-3 of the washing tub 100. Mounting portion 210-1 fits over the upper end of the agitator shaft 300. The radial dimension of mounting portion 210-1 is only three to five times the diameter of the upper end of the agitator shaft 300, making it very small. Combined with the structure of the water-stirring rib 220 above mounting portion 210-1, the area of ​​the bottom 100-3 of the washing tub 100 located outside the mounting groove 100-1 is fully exposed, minimizing the risk of dirt and debris accumulating between the water-stirring member 200 and the washing tub 100.

[0215] Example 3

[0216] As shown in Figures 19 to 21, this embodiment is a further limitation of the above-mentioned embodiment 2. 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 has a cavity arranged axially from the top end toward the assembly portion 210-1.

[0217] 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.

[0218] 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.

[0219] In this embodiment, the support column 210 includes an assembly portion 210-1 and a hollow column 210-8 coaxially connected to the upper portion of the assembly portion 210-1. The assembly 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 assembly portion 210-1. The outer diameter of the hollow column 210-8 at the connection between the assembly portion 210-1 and the assembly portion 210-1 can be greater than the diameter of the assembly portion 210-1, or less than or equal to the diameter of the assembly portion 210-1. The outer wall of the hollow column 210-8 smoothly transitions upward with the outer wall of the assembly portion 210-1.

[0220] 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.

[0221] Preferably, the water stirring rib 220 is also configured as a hollow structure.

[0222] Further preferably, the internal space of the water stirring rib 220 is connected to the cavity 210-9 inside the hollow column 210-8.

[0223] 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 connection strength between the assembly portion 210 - 1 and the water-stirring portion 240 .

[0224] In this embodiment, the water stirring portion 240 is connected to the stirring shaft 300 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 .

[0225] Specifically, the assembly portion 210 - 1 and the stirring shaft 300 are circumferentially positioned by splines and rotate together, and are axially positioned by screws 210 - 7 .

[0226] In this embodiment, the assembly portion 210-1 is provided with a spline groove 210-6 extending coaxially upward from the bottom end surface of the assembly portion 210-1. The spline groove 210-6 is at least partially sleeved on the upper end portion of the agitator shaft 300 and is keyed to the agitator shaft 300. The spline groove 210-6 is formed on the assembly portion 210-1 of the water-stirring member 200.

[0227] 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 300 keyed to the assembly portion 210-1, thereby axially securing the agitating member 200 to the agitating shaft 300. To prevent water from entering the cavity 210-9, a sealing member is installed at the opening.

[0228] 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.

[0229] 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.

[0230] 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 .

[0231] 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.

[0232] The top of the flat plate portion and the top of the water-stirring member 200 are in the same plane.

[0233] 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.

[0234] 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.

[0235] In this embodiment, a sealing ridge extending circumferentially along the central portion of the plug-in portion is provided. 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 in multiple circles spaced apart along the axial direction of the plug-in portion.

[0236] 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 .

[0237] This embodiment provides a specific assembly structure for the agitating member 200 and the agitating shaft 300. By providing a hollow interior of the agitating portion 240 of the agitating member 200, screws 210-7 can be installed from top to bottom to secure the agitating member 200 and the agitating shaft 300. This also reduces the overall weight of the agitating member 200, further reducing the energy consumption of the motor driving the agitating member 200. The provision of a sealing cap 210-5 prevents wash water from entering the agitating member 200, thereby preventing lint or dirt from entering with the wash water and remaining inside the agitating member 200, where it cannot be cleaned.

[0238] Example 4

[0239] As shown in Figures 19 to 21, this embodiment is a further limitation of the above-mentioned embodiment 2 or 3. The water stirring member 200 includes a mounting portion 210-1 and a water stirring portion 240 extending upward from the mounting portion 210-1. The stirring shaft 300 rotatably passes through the center of the barrel bottom 100-3 and is connected to the mounting portion 210-1.

[0240] As a specific embodiment, the distance between the sidewall of the mounting portion 210-1 and the inner surface of the peripheral wall of the washing tub 100 is close to the distance between the sidewall of the agitator shaft 300 and the inner surface of the peripheral wall of the washing tub 100. More specifically, the distance between the sidewall of the mounting portion 210-1 and the inner surface of the peripheral wall of the washing tub 100 is slightly smaller than the distance between the sidewall of the agitator shaft 300 and the inner surface of the peripheral wall of the washing tub 100.

[0241] In this way, the bottom surface of the washing tub 100 is substantially completely exposed to the washing space above, thus avoiding the problem of dirt and grime accumulating at the tub bottom 100 - 3 .

[0242] In this embodiment, the dehydration shaft 110 connected to the washing barrel 100 is mounted on the stirring shaft 300. At the upper end of the dehydration shaft 110, a sealing structure 120 is provided between the dehydration shaft 110 and the stirring shaft 300, so that the dehydration shaft 110 and the stirring shaft 300 can be sealed and connected in a relatively rotatable manner to prevent water from entering between the dehydration shaft 110 and the stirring shaft 300.

[0243] Specifically, the sealing structure 120 is sleeved on the stirring shaft 300 , and the outer peripheral wall of the sealing structure 120 is relatively fitted with the inner peripheral wall of the dehydration shaft 110 .

[0244] As a specific embodiment, the upper end surface of the sealing structure 120 is flush or substantially flush with the inner surface of the barrel bottom 100 - 3 , thereby preventing a gap that is easy to harbor dirt and grime from being formed between the dehydration shaft 110 and the stirring shaft 300 .

[0245] The above-mentioned “substantially flush” means that the upper end surface of the sealing structure 120 may be slightly higher than the inner surface of the barrel bottom 100 - 3 , or slightly lower than the inner surface of the barrel bottom 100 - 3 .

[0246] In a configuration where the upper end surface of the sealing structure 120 is slightly higher than the inner surface of the barrel bottom 100-3, no concave gap is formed between the dehydration shaft 110 and the stirring shaft 300. In a configuration where the upper end surface of the sealing structure 120 is slightly lower than the inner surface of the barrel bottom 100-3, a concave gap is formed, but the size of the concave gap is very small. The flushing force of the water flowing through this gap during washing is sufficient to remove lint and dirt from this area, and no dirt will remain.

[0247] In one embodiment, the lower end surface of the agitating member 200, i.e., the lower end surface of the mounting portion 210-1, is at least partially opposed to the upper end surface of the sealing structure 120. The mounting portion 210-1 is mounted on the upper end of the agitating shaft 300, and the diameter of the lower end of the mounting portion 210-1 is larger than the diameter of the agitating shaft 300.

[0248] Furthermore, the diameter of the lower end of the fitting portion 210 - 1 is greater than the outer diameter of the sealing structure 120 .

[0249] In a specific embodiment, the difference between the diameter of the lower end of the assembly portion 210 - 1 and the outer diameter of the sealing structure 120 is close to the wall thickness of the assembly portion 210 - 1 in the radial direction.

[0250] In this embodiment, the specific assembly relationship between the bottom of the water stirring member 200, the stirring shaft 300 and the barrel bottom 100-3 further ensures that the barrel bottom 100-3 does not harbor dirt.

[0251] Example 5

[0252] As shown in FIG. 23 , the difference between this embodiment and the above-mentioned embodiment 1 is that the assembly portion 210 - 1 is no longer the minimum radius section within a certain height range at the bottom of the water-stirring member 200 .

[0253] Specifically, in this embodiment, the maximum radius Rmax is formed on the water stirring portion 240 of the water stirring member 200 at a certain height away from the assembly portion 210-1. Between the bottom end of the water stirring portion 240 and the maximum radius Rmax, the horizontal cross-sectional radius of the water stirring portion 240 is smaller than the maximum radius of the assembly portion 210-1 at least within a certain height range.

[0254] As a specific embodiment, the horizontal cross-sectional radius of the water-stirring portion 240 gradually decreases upward from the bottom end connected to the assembly portion 210-1 until a horizontal cross-sectional radius with the smallest radius is formed, and then gradually increases with increasing height until the maximum radius Rmax of the water-stirring component 200 is formed.

[0255] It is understood that the horizontal cross-section with the smallest radius refers to the horizontal cross-section with the smallest radius located below the maximum radius Rmax. For solutions in which the maximum radius Rmax is not located at the top of the water stirring portion 240, the water stirring portion 240 may also have a horizontal cross-section with a smaller radius above the maximum radius Rmax.

[0256] In one detailed configuration, the aforementioned changing trend in the horizontal cross-sectional radius of the water-stirring portion 240 is caused by the water-stirring ribs 220. Specifically, the radius of the support column 210 along the axial direction remains consistent, and the water-stirring ribs 220 are disposed on the sidewalls of the support column 210. The radial dimension of the water-stirring ribs 220 first decreases and then increases with increasing height, thereby ensuring that, within a certain height range, the radius of the water-stirring portion 240 is smaller than the radius of the assembly portion 210-1.

[0257] Furthermore, since the mounting portion 210-1 has a larger radius, the lower end surface area of ​​the mounting portion 210-1 is larger. To prevent dirt and grime from accumulating between the lower end surface of the mounting portion 210-1 and the tub bottom 100-3, a certain distance is provided between the lower end surface of the mounting portion 210-1 and the inner surface of the tub bottom 100-3. This distance allows clothing to contact the lower end surface of the mounting portion 210-1.

[0258] Specifically, in this embodiment, the assembly part 210-1 is mounted on the upper end of the stirring shaft 300. After installation, the lower end surface of the assembly part 210-1 is kept at a certain distance from the inner surface of the barrel bottom 100-3, and the downward projection of the lower end surface of the assembly part 210-1 falls directly on the inner surface of the barrel bottom 100-3.

[0259] The projection falls directly onto the inner surface of the tub bottom 100-3. This means that the lower end surface of the mounting portion 210-1 is projected downwardly onto the inner surface of the tub bottom 100-3 without obstruction. Specifically, between the lower end surface of the agitating member 200 and the inner surface of the tub bottom 100-3, the sidewall of the agitator shaft 300 directly faces the tub wall of the washing tub 100, without a pulsator or other large radially extending structure disposed thereon.

[0260] With the above structure, during the washing process, the lower end surface of the assembly part 210-1 and the inner surface of the barrel bottom 100-3, especially the area near the center of the inner surface of the barrel bottom 100-3, can be completely exposed in the washing space and come into contact with the clothes during washing, thereby avoiding the problem of dirt and grime accumulating between the lower end surface of the assembly part 210-1 and the barrel bottom 100-3.

[0261] In a preferred embodiment of the present invention, the barrel bottom 100-3 has a raised surface at the center. In this way, an angle greater than 90° can be formed between the inner surface of the barrel bottom 100-3 and the side wall of the stirring shaft 300 on the periphery of the stirring shaft 300, making it easier to fully expose the area of ​​the barrel bottom 100-3 close to the center and the area of ​​the side wall of the stirring shaft 300 close to the barrel bottom 100-3, thereby making it more conducive to the contact between the above-mentioned areas and the clothes and preventing the adhesion and accumulation of dirt.

[0262] This embodiment has the above-mentioned specific structure. When the washing machine uses a water level lower than the maximum radius Rmax of the water stirring member 200 for washing, the water stirring member 200 rotates relative to the washing tub 100 to drive the clothes to follow the water flow. A specific motion path is as follows:

[0263] The clothes move toward the center along the bottom 100-3 of the washing tub 100 in the bottom area, move to the side wall of the stirring shaft 300, and then move upward along the side wall of the stirring shaft 300 to the lower end surface of the assembly part 210-1; the clothes here move toward the periphery along the lower end surface of the assembly part 210-1, and after moving to a point beyond the coverage of the lower end surface of the assembly part 210-1, continue to rise along the side of the water-stirring member 200; during the rising process of the clothes, after exceeding the top of the assembly part 210-1, a movement trend toward the central axis is generated, and then after moving obliquely upward toward the central axis for a certain distance, the clothes continue to rise obliquely toward the periphery; the clothes can rise as high as below the maximum radius Rmax of the water-stirring member 200 or the height of the washing water level, and then move toward the periphery, and finally fall along the barrel wall of the washing tub 100 to the barrel bottom 100-3.

[0264] In this embodiment, the assembly portion 210-1 of the water-stirring member 200 is no longer the minimum radius section of the water-stirring member 200 below the area of ​​maximum radius Rmax. Instead, at a certain height above the assembly portion 210-1, the water-stirring member 240 first forms a minimum radius and then continues upward to form the maximum radius Rmax. The increased radius of the portion of the water-stirring member 200 near the bottom 100-3 can enhance the agitation of the washing water in the bottom area of ​​the washing tub 100, thereby improving the washing effect to a certain extent. By increasing the installation height of the water-stirring member 200, sufficient spacing can be reserved between the lower end surface of the assembly portion 210-1 and the inner surface of the bottom 100-3, allowing clothes to contact the lower end surface of the assembly portion 210-1. In combination with the enhanced water flow intensity of the washing water in the bottom area of ​​the washing tub 100, the lower end surface of the assembly portion 210-1 and the inner surface of the bottom 100-3 can be effectively flushed to prevent dirt from adhering.

[0265] Example 6

[0266] As shown in FIG. 2 and FIG. 3 , this embodiment provides a washing tub assembly and a washing device having the washing tub assembly.

[0267] Specifically, the washing tub assembly of this embodiment includes a washing tub 100 and a water stirring member 200 rotatably disposed within the washing tub 100. The water stirring member 200 extends upward from the bottom of the washing tub 100 and has a maximum radius at a certain distance from the bottom 100-3 (i.e., the bottom surface of the washing tub 100). This certain distance allows at least some clothes C to be washed below the location of the maximum radius Rmax of the water stirring member 200.

[0268] The water-stirring member 200 and the washing tub 100 described in this embodiment have the aforementioned mating structure. Compared to conventional pulsator washing machines or agitator washing machines with radial agitators, a washing space is defined below the maximum radius Rmax of the water-stirring member 200. This washing space is formed by the surface of the water-stirring member 200 below the maximum radius Rmax, the walls of the washing tub 100, and the bottom of the washing tub 100. Clothes C can be washed within this washing space, allowing the surface of the water-stirring member 200 below the maximum radius Rmax and the bottom of the washing tub 100 to come into contact with the laundry C within the tub. During the washing process, friction between the laundry C and the surface of the water-stirring member 200 prevents lint and other dirt from adhering to the surface of the water-stirring member 200, effectively avoiding the problem of dirt easily accumulating between the water-stirring member 200 and the bottom of the tub, making it difficult to clean. This improves the user experience.

[0269] At the same time, since the clothes C can be washed in the space between the maximum radius Rmax of the water-stirring member 200 and the bottom of the washing tub 100, and there will be no situation where the clothes C cover the water-stirring member 200 over a large area as in a pulsator washing machine, the resistance of the clothes C to the rotation of the water-stirring member 200 can be reduced, thereby reducing the energy consumption of the motor of the driving device that drives the water-stirring member 200 to rotate.

[0270] In this embodiment, the radius of the agitating member 200 refers to the distance between the point on the agitating member 200 that is farthest from the center of rotation and the center of rotation, as measured along a cross section perpendicular to the axis of rotation (see FIG. 4 ). Specifically, this is similar to the definition of the "radius of the horizontal cross section of the agitating portion 240" in the first embodiment.

[0271] As a specific implementation, in this embodiment, the distance h between the maximum radius Rmax of the water stirring member 200 and the barrel bottom 100-3 is greater than 10 cm, thereby ensuring that the clothes C can be washed below the maximum radius Rmax.

[0272] In a further solution of this embodiment, the water stirring member 200 forms a first guide surface extending toward the periphery at its maximum radius Rmax. During washing, the first guide surface can guide the clothes C located below the maximum radius Rmax to move toward the periphery along the first guide surface.

[0273] Specifically, during the washing process, the drive device drives the water-stirring member 200 to rotate independently, or drives the water-stirring member 200 and the washing tub 100 to rotate in opposite directions, thereby generating relative rotation between the water-stirring member 200 and the washing tub 100. The provision of the first guide surface allows the clothing C to move from the central area toward the periphery below the maximum radius Rmax of the water-stirring member 200. After moving a certain distance toward the periphery, or after moving beyond the coverage of the first guide surface, the clothing C will fall under the influence of gravity and the water flow. This enhances the effect of the water-stirring member 200 rotating during the washing process, causing the clothing C to move toward the periphery and flip, thereby improving the washing effect and preventing the clothing C from gathering toward the center and becoming entangled.

[0274] In a further solution of this embodiment, the maximum radius Rmax of the water-stirring component 200 is also at a certain distance from the barrel mouth of the washing barrel 100 in the height direction, so that the washing water level can be higher than the maximum radius Rmax of the water-stirring component 200, so that the clothes C can be washed above the position of the maximum radius Rmax of the water-stirring component 200.

[0275] In the above scheme, the washing tub 100 can accommodate clothes C for washing above and below the maximum radius Rmax of the water-stirring member 200. In this way, the outer surface of the water-stirring member 200 can basically contact the washed clothes C, generating friction with the clothes C, and the washing effect can be enhanced by increasing the surface area in contact with the clothes C.

[0276] In this embodiment, the side of the water stirring member 200 is configured such that as the height of the rotation axis increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 remains constant or changes gradually or stepwise.

[0277] As a specific embodiment, as shown in Figures 2 and 12 to 14 , the water-stirring member 200 has a single maximum radius Rmax in the height direction. Furthermore, at least below this maximum radius Rmax, the distance between the side surface of the water-stirring member 200 and the wall of the washing tub 100 decreases with increasing height, ultimately forming a first guide surface extending toward the periphery at the maximum radius Rmax.

[0278] It should be noted that the single maximum radius Rmax may refer to the water-stirring member 200 having the maximum radius Rmax at a specific height position, or may refer to the water-stirring member 200 having the maximum radius Rmax within a certain continuous height range.

[0279] In the first embodiment, as shown in Figure 12 , the maximum radius Rmax of the agitating member 200 is located at the top of the agitating member 200. That is, the top surface of the agitating member 200 is the cross-section with the maximum radius. A first guide surface is formed on the underside of the top of the agitating member 200. During washing, clothing that approaches the top of the agitating member 200 moves outward along the first guide surface.

[0280] In the second embodiment, as shown in Figure 2 , the maximum radius Rmax of the agitating member 200 is located near the top of the agitating member 200, but at a distance therefrom. Specifically, the upper surface of the agitating member 200 at its maximum radius Rmax is an upwardly convex curved surface, with the highest point of the curved surface forming the top of the agitating member 200. In this embodiment, the first guide surface is formed at a position similar to that of the previous embodiment, also below the top of the agitating member 200.

[0281] In the third specific solution, as shown in FIG. 13 and FIG. 14 , the maximum radius Rmax of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0282] In one detailed embodiment, as shown in FIG13 , the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 continuously changes in height. Specifically, as the height increases, the radius of the water-stirring member 200 gradually increases from the bottom of the washing tub 100 upward until reaching the maximum radius Rmax. Thereafter, the radius of the water-stirring member 200 gradually decreases until it reaches the top of the water-stirring member 200.

[0283] In the above solution, the first guide surface is formed in the middle of the water stirring member 200 in the height direction, and the laundry washed below the maximum radius Rmax of the water stirring member 200 can move toward the periphery along the first guide surface.

[0284] In another detailed embodiment, as shown in Figure 14, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 changes abruptly at at least one height. Specifically, as the height increases, the radius of the water-stirring member 200 gradually increases from the bottom of the washing tub 100 upwards. At a certain height, the radius suddenly increases, forming the maximum radius Rmax. The radius of the water-stirring member 200 then remains constant within a certain height range before suddenly decreasing, and then continues to gradually decrease, ultimately forming the top of the water-stirring member 200. In this embodiment, the distance h from the maximum radius Rmax on the water-stirring member 200 to the bottom of the washing tub 100 refers to the distance from the lowest height within the height range where the radius of the water-stirring member 200 remains constant to the bottom of the washing tub 100.

[0285] In the above embodiment, the distance from the maximum radius Rmax of the water-stirring member 200 to the bottom of the washing tub 100 refers to the distance from the lowest height within the height range where the radius of the water-stirring member 200 remains constant to the bottom of the washing tub 100. The first guide surface includes at least the surface facing the bottom of the washing tub 100 formed at the point where the radius of the water-stirring member 200 suddenly changes.

[0286] As another specific embodiment, as shown in Figure 16 , the agitating member 200 has a plurality of maximum radii Rmax spaced apart along the axis of the washing tub 100. Specifically, as the height increases, the radius of the agitating member 200 alternately increases and decreases, each time increasing to a constant radius and then decreasing, thereby forming multiple spaced maximum radii Rmax spaced apart. In this embodiment, each maximum radius Rmax of the agitating member 200 forms a first guide surface extending outward, thereby driving clothing toward the periphery at different heights.

[0287] The different structures provided above can all enable clothes to be washed below the maximum radius Rmax of the water stirring member 200, preventing the existence of cleaning dead corners between the water stirring member 200 and the bottom of the washing tub 100 where dirt is easily accumulated, and forming a first guide surface at the maximum radius Rmax to guide clothes to move toward the periphery, thereby reducing the entanglement of clothes.

[0288] In a further embodiment of the present invention, the water-stirring member 200 further includes a second, upwardly extending guide surface below the point of maximum radius Rmax, for guiding the clothing C along the second guide surface toward the point of maximum radius Rmax of the water-stirring member 200 during washing. The cooperation of the first and second guide surfaces allows the clothing C to be washed while moving along a circular path below the point of maximum radius Rmax of the water-stirring member 200.

[0289] In this embodiment, the height at which the maximum radius Rmax of the water-stirring member 200 is located is positioned between the highest and lowest water levels of the washing machine. This allows the rotation of the water-stirring member 200 to generate different water flows when washing at different water levels. In particular, as a specific embodiment, below the maximum radius Rmax of the water-stirring member 200, the clothes C can be washed along a circular path.

[0290] The circular path mentioned above means that the water moves toward the center of the bottom area of ​​the washing tub 100, is lifted by the water stirring member 200 to a position close to the maximum radius Rmax of the water stirring member 200, moves toward the periphery, and then falls.

[0291] 17 and 18 , as a specific solution, the circular path of the movement of the clothes below the maximum radius Rmax of the water-stirring member 200 during washing includes: the clothes move along the bottom of the washing tub 100 toward the central area, move upward along the side of the water-stirring member 200 in the central area to below the maximum radius Rmax and then move toward the periphery, and move downward in the area close to the wall of the washing tub 100.

[0292] In a further embodiment of the present invention, the water-stirring member 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water-stirring rib 220 protruding from the side wall of the support column 210. The support column 210 is used to transmit a drive connected to the washing apparatus, thereby allowing the water-stirring member 200 to rotate under the drive of the drive. As the water-stirring rib 220 rotates within the washing tub 100, it stirs the clothes C and the water flow within the tub. The bottom of the washing tub 100, the side walls of the support column 210, and the walls of the washing tub 100 together form a space capable of accommodating the clothes C being washed, and the clothes C can move along the aforementioned circular path within the space.

[0293] When the washing tub assembly of this embodiment is applied to a washing device, in a specific implementation, as shown in FIG17 , when operating at a low water level W1 lower than the maximum radius Rmax of the water stirring member 200 , the clothes can move in the water along the circular path described above.

[0294] Specifically, during the washing process, the water-stirring member 200 and the washing tub 100 rotate relative to each other, causing the clothing to move along the path indicated by the arrow in the figure within the space below the maximum radius Rmax of the water-stirring member 200. Specifically, the clothing moves along the bottom of the washing tub 100 toward the center, where it is collected. In the center, the clothing is lifted along the sidewalls of the support column 210 or the outer edges of the water-stirring ribs 220 to below the maximum radius Rmax. The clothing then moves toward the periphery before falling to the bottom of the washing tub 100 near the wall, forming a circular motion.

[0295] As shown in Figure 18, when operating at a high water level W2 that is higher than the maximum radius Rmax of the water stirring member 200, in the area below the maximum radius Rmax of the water stirring member 200, the clothes move along the above-mentioned circular path in the water; and in the area above the maximum radius Rmax of the water stirring member 200, the clothes move close to the circumferential direction of the washing tub 100.

[0296] Specifically, during the washing process, the agitating member 200 and the washing tub 100 rotate relative to each other. Within the area below the maximum radius Rmax of the agitating member 200, the clothing moves along a path substantially consistent with that at the low water level W1. Above the maximum radius Rmax of the agitating member 200, the clothing moves along the circumference of the washing tub 100 in alternating forward and reverse motion, following the alternating forward and reverse rotation of the agitating member 200.

[0297] In the above solution, when using different wash water levels, the agitating member 200 can move the clothes in the tub in different ways for washing, providing more diverse washing options. Furthermore, in the area below the maximum radius Rmax of the agitating member 200, the clothes move along a circular path, which not only enhances the tumbling of the clothes and improves the washing effect, but also avoids the problem of clothes tending to converge toward the center and causing entanglement in existing pulsator washing machines.

[0298] In this embodiment, the protrusion direction of the water-stirring rib 220 on the side wall of the support column 210 coincides with the radial direction of the washing tub 100, or forms an angle less than 90° with the radial direction of the washing tub 100. In this way, when the water-stirring rib 220 rotates with the water-stirring member 200, the surface of the water-stirring rib 220 is arranged opposite to the direction of rotation, thereby achieving an effective stirring effect.

[0299] More specifically, a plurality of agitating ribs 220 are circumferentially spaced apart on the sidewall of the support column 210. These agitating ribs 220 are preferably arranged symmetrically with respect to the axis of rotation. Clothes C can be washed in the space between two adjacent agitating ribs 220, thereby contacting both sides of the agitating ribs 220 and the area between the two agitating ribs 220 on the sidewall of the support column 210, thereby avoiding blind spots on the sidewall of the support column 210 where dirt easily accumulates. Furthermore, during washing, clothes C moving along the bottom of the washing tub 100 toward the center are lifted along the sidewall of the support column 210 to below the maximum radius Rmax of the agitating member 200, then moving toward the periphery before falling, forming a circular path.

[0300] The water-stirring member 200 having the above-mentioned structure has a side surface including both the side wall of the support column 210 and the surface of the water-stirring rib 220 that is farthest from the rotation axis, and the radius of the water-stirring member 200 is the distance between the farthest surface from the rotation axis on the water-stirring rib 220 and the rotation axis.

[0301] In the above structure, the radius of the agitating member 200 specifically refers to the distance from the point at which the agitating rib 220 is furthest from the axis to the center axis on a horizontal cross-section of the agitating member 200. When the number of agitating ribs 220 is even, the length of the line connecting the points at which two agitating ribs 220 are furthest from the axis is the diameter of the agitating member 200 at that point. When the number of agitating ribs 220 is odd, there are no opposing agitating ribs 220. In this case, the horizontal cross-section of the agitating portion 240 does not form an axisymmetric figure. However, the diameter of the horizontal cross-section of the agitating portion 240 is still twice the distance from the point at which the agitating rib 220 is furthest from the axis to the center axis.

[0302] In another embodiment, the agitating ribs extend spirally along the sidewall surrounding the support column. In this case, a horizontal cross-section of the agitating member may not form a regular geometric shape, and the radius is still the distance from the farthest end of the agitating rib from the axis to the central axis in the cross-section.

[0303] As a specific solution of this embodiment, as shown in FIG. 2 and FIG. 12 , below the maximum radius Rmax of the water-stirring member 200 , the support column 210 has or substantially maintains the same radius along the axial direction.

[0304] The support column 210 having a uniform radius along the axial direction means that the sidewall of the support column 210 extends upward in the vertical direction until it reaches the position of the maximum radius Rmax of the water-stirring member 200. The support column 210 maintaining substantially a uniform radius along the axial direction may mean that the sidewall of the support column 210 extends upward along a straight line that is close to the vertical direction until it reaches the position of the maximum radius Rmax of the water-stirring member 200.

[0305] The water-stirring rib 220 protrudes from the sidewall of the support column 210 and has a certain height along the axial direction of the washing tub 100. The radial dimension of the water-stirring rib 220 increases with increasing height of the washing tub 100, thereby forming a structure in which the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 decreases with increasing height.

[0306] Furthermore, the lower end of the water-stirring rib 220 is spaced apart from the bottom of the washing tub 100. Specifically, the bottom of the support column 210 has a mounting portion for connecting to the agitator shaft 300. The outer edge of the water-stirring rib 220 extends upward at an angle from a point on the sidewall of the support column 210 at a predetermined distance from the upper end of the mounting portion. The angle of inclination remains constant or gradually changes, ultimately extending to the height of the maximum radius Rmax of the water-stirring member 200. There is no other structure extending radially along the washing tub 100 between the lower end of the water-stirring rib 220 and the mounting portion, and the water-stirring rib 220 does not cover the bottom of the washing tub 100, ensuring that there is essentially no area on the bottom of the washing tub 100 that is inaccessible to clothing.

[0307] In the first embodiment, the bottom of the washing tub 100 is provided with a recessed structure with an open top. The agitator shaft 300 extends into the interior of the washing tub 100 through a mounting hole provided in the bottom wall of the recessed structure. The mounting portion rotatably engages with the recessed structure, and the lower end of the agitator rib 220 is not lower than the upper end of the mounting portion, thereby allowing the lower end surface of the agitator rib 220 to contact clothing. Furthermore, since there is no other structure extending radially along the washing tub between the lower end of the agitator rib 220 and the mounting portion, the area of ​​the bottom of the washing tub 100 located outside the recessed structure can also contact clothing, preventing the adhesion of lint and dirt.

[0308] In a second embodiment, a gap is formed between the lower end surface of the mounting portion and the bottom of the washing tub. The agitator shaft 300 passes through a mounting hole formed in the bottom of the washing tub 100 and is connected to the mounting portion. This gap allows both the lower end surface of the mounting portion and the area of ​​the bottom of the washing tub 100 located outside the mounting hole to contact clothing, preventing the formation of blind spots where dirt can easily accumulate.

[0309] In a third embodiment, the agitator shaft 300 extends into the washing tub 100 through a mounting hole in the bottom of the washing tub 100. The mounting portion fits over the upper end of the agitator shaft 300, leaving a small gap between the lower end of the mounting portion and the bottom of the washing tub 100. The difference between the outer and inner diameters of the mounting portion's bottom is sufficiently small to allow the outer surface of the mounting portion to contact clothing during washing. Furthermore, the area of ​​the washing tub 100 bottom surrounding the mounting hole can also contact clothing, preventing the formation of blind spots where dirt can easily accumulate. Preferably, a smooth transition is formed between the outer wall of the mounting portion and the sidewall of the agitator shaft 300, further eliminating the possibility of blind spots during cleaning.

[0310] Regarding the solution in which the maximum radius Rmax of the water-stirring member 200 is located at or close to the top of the water-stirring member 200, as a specific implementation, as shown in Figure 12, the maximum radius Rmax of the water-stirring member 200 is formed by the upper end of the outer peripheral edge of the water-stirring rib 220.

[0311] As another specific embodiment, as shown in FIG2 , the water-stirring member 200 further includes a water-stirring pan 230 connected to the upper end of the support column 210. The outer periphery of the water-stirring pan 230 defines the maximum radius Rmax of the water-stirring member 200. The upper end of the water-stirring rib 220 is connected to the lower surface of the water-stirring pan 230, thereby preventing the formation of a dead corner between the water-stirring rib 220 and the water-stirring pan 230, which is inaccessible to clothing C and easily harbors dirt.

[0312] Furthermore, the agitating member 200 of this embodiment has a guide surface extending outwardly below the maximum radius Rmax. During washing, the clothes C lifted below the maximum radius Rmax of the agitating member 200 move outwardly along the guide surface. More specifically, in this embodiment, the guide surface includes the lower surface of the agitating tray 230.

[0313] Preferably, a smoothly curved transition surface is provided between the upper end of the sidewall of the support column 210 and the lower surface of the water-stirring pan 230. More preferably, rounded corners are provided between the two side surfaces of the water-stirring rib 220 and the lower surface of the water-stirring pan 230. This further reduces hard-to-clean corners on the water-stirring member 200.

[0314] As a specific solution, in this embodiment, the upper end of the water-stirring rib 220 is aligned with the outer periphery of the water-stirring plate 230 away from the support column 210, so that the radial dimension of the water-stirring rib 220 along the washing tub 100 is maximized as much as possible, thereby enhancing the agitation of the washing water and improving the washing effect.

[0315] When washing clothes C, the washing device having the washing tub assembly described in this embodiment can drive the clothes C to move along a circular path below the maximum radius Rmax of the water stirring member 200 by controlling the water stirring member 200 to rotate relative to the washing tub 100 for washing.

[0316] Specifically, at the bottom of the washing tub 100, the stirring action of the water flow by the water stirring member 200 creates a radial flow pattern within the washing tub 100, thereby driving the clothing C along the bottom of the washing tub 100 toward the center. Clothes C converging toward the center come into contact with the side surfaces of the water stirring member 200 and, due to the rotation of the water stirring member 200, are lifted upward until they reach the bottom of the maximum radius Rmax of the water stirring member 200. Below the maximum radius Rmax of the water stirring member 200, the upward movement of the water flow and clothing C is blocked, causing them to move outward along the guiding surface below the maximum radius Rmax of the water stirring member 200. Ultimately, near the wall of the washing tub 100, or after contacting the wall, they descend back to the bottom of the washing tub 100 due to gravity and the water flow.

[0317] In this embodiment, the water-stirring member 200 installed in the washing tub 100 forms a maximum radius Rmax at a certain distance from the tub bottom, and does not have a disc-shaped water-stirring portion near the bottom of the tub. This allows the clothes C to be washed below the maximum radius Rmax, leaving a large portion of the bottom surface of the washing tub 100 exposed to the wash water and accessible to the washed clothes C. During the washing process, the clothes C can come into contact with the bottom of the washing tub 100 and the outer surface of the water-stirring member 200 located below the maximum radius Rmax, generating friction. This effectively avoids the problem of a blind spot between the water-stirring member 200 and the washing tub 100, which can easily accumulate lint and dirt.

[0318] On the other hand, during the washing process, the water-stirring component 200 can drive the clothes C to gather at the bottom of the barrel toward the center, then be lifted to a certain height, and then guide the clothes C to move toward the periphery and then fall, thereby moving along a circular path around the water-stirring component 200, which can not only enhance the washing effect, but also prevent the clothes C from getting entangled.

[0319] Example 7

[0320] As shown in Figures 2 and 3, this embodiment further defines the sixth embodiment described above. The water-stirring member 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water-stirring tray 230 perpendicularly arranged to the axis of the support column 210. The support column 210 is used to transmit power to a drive device connected to the washing machine, thereby allowing the water-stirring member 200 to rotate under the drive device. The outer periphery of the water-stirring tray 230 defines the maximum radius Rmax of the water-stirring member 200. The first guide surface is formed on the underside of the water-stirring tray 230, extending horizontally or obliquely upward from a region near the center of the water-stirring tray 230 toward the outer periphery.

[0321] The second guide surface is formed on the side of the support column 210. During washing, the clothes C move along the bottom of the washing tub 100 toward the central area, then move upward along the second guide surface to the first guide surface, move toward the periphery along the first guide surface, and then fall back to the bottom of the tub along the wall of the washing tub.

[0322] In the above embodiment, during the washing process, the water-stirring member 200 and the washing tub 100 rotate relative to each other. Because the radius of the water-stirring member 200 near the bottom of the tub is smaller, during washing, the clothes C at the bottom of the washing tub 100 can converge along the bottom toward the center, then move upward along the second guide surface to below the first guide surface, then move outward along the first guide surface, and finally fall along the tub wall to the bottom area, thus forming a circular motion path that rotates from the center outward.

[0323] In this embodiment, the height at which the maximum radius Rmax of the water-stirring member 200 is located is also set between the highest water level and the lowest water level of the washing equipment.

[0324] The washing tub assembly is applied to a washing machine. As shown in FIG17 , when the washing tub assembly is operated at a low water level W1 lower than the maximum radius Rmax of the water stirring member 200 , the clothes move along a reverse circular path in the water.

[0325] In detail, during the washing process, relative rotation occurs between the water stirring member 200 and the washing tub 100, and the clothes move along the path indicated by the arrow in the figure in the space below the maximum radius Rmax of the water stirring member 200, move toward the central area along the bottom of the washing tub 100 and gather, and then are lifted to the bottom of the first guide surface along the second guide surface formed by the side wall of the support column 210, and then move toward the periphery along the first guide surface, and then fall to the bottom of the tub in the area close to the wall of the washing tub 100, forming a circular motion.

[0326] As shown in Figure 18, when operating at a high water level W2 that is higher than the maximum radius Rmax of the water stirring member 200, in the area below the maximum radius Rmax of the water stirring member 200, the clothes move along the above-mentioned circular path in the water; and in the area above the maximum radius Rmax of the water stirring member 200, the clothes move close to the circumferential direction of the washing tub 100.

[0327] Specifically, during the washing process, the agitating member 200 rotates relative to the washing tub 100. Within the area below the maximum radius Rmax of the agitating member 200, the clothing moves along a path substantially consistent with that at the low water level W1. Above the maximum radius Rmax of the agitating member 200, the clothing moves along the circumference of the washing tub 100 in alternating forward and reverse motion, following the alternating forward and reverse rotation of the agitating member 200.

[0328] In this embodiment, the radius of the connection between the support column 210 and the lower surface of the water stirring tray 230 is smaller than the radius of the water stirring tray 230. That is, most of the lower surface of the water stirring tray 230 is exposed to the interior space of the washing tub 100. The first guide surface includes at least a portion of the lower surface of the water stirring tray 230, and the second guide surface includes at least the area of ​​the side wall of the support column 210 located below the water stirring tray 230.

[0329] As a specific embodiment, as shown in Figure 2, the water stirring tray 230 is connected to the upper end of the support column 210. Specifically, the upper end of the support column 210 is connected to the center of the lower surface of the water stirring tray 230, and the area of ​​the lower surface of the water stirring tray 230 not covered by the upper end surface of the support column 210 forms the first guide surface.

[0330] More specifically, the sidewalls of the support column 210 extend upward from the bottom of the washing tub 100 in a vertical direction or a nearly vertical direction until they connect with the lower surface of the water-stirring member 200. The sidewalls of the support column 210, starting from an area higher than the bottom surface of the washing tub 100, can serve as the second guide surface.

[0331] In a further embodiment, a transitional curved surface for smooth transition is provided at the junction of the sidewall of the support column 210 and the lower surface of the water-stirring pan 230, and the first guide surface also includes the transitional curved surface. This avoids a blind spot between the upper end of the support column 210 and the water-stirring pan 230 where the clothes C are difficult to reach.

[0332] In a further solution of this embodiment, the water-stirring component 200 also includes a water-stirring rib 220 protruding from the side wall of the support column 210. On the lower side of the water-stirring plate 230, the water-stirring rib 220 has a certain extension length along the axial direction of the washing bucket 100, and the upper end of the water-stirring rib 220 is connected to the first guide surface.

[0333] In this embodiment, a plurality of water-stirring ribs 220 are circumferentially spaced apart on the sidewall of the support column 210. Clothes C can be washed in the space between two adjacent water-stirring ribs 220, thereby contacting both sides of the water-stirring ribs 220 and the area between the two water-stirring ribs 220 on the sidewall of the support column 210. This avoids blind spots on the sidewall of the support column 210 where dirt easily accumulates, while also ensuring that the second guide surface formed by the sidewall of the support column 210 effectively guides the clothes C upward.

[0334] As a specific embodiment, the upper end of the water-stirring rib 220 is aligned with the outer periphery of the water-stirring plate 230 away from the axis of the support column 210, so that the radial dimension of the water-stirring rib 220 along the washing tub 100 is maximized as much as possible, thereby enhancing the agitation of the washing water and improving the washing effect.

[0335] When washing clothes C, the washing device having the washing tub assembly described in this embodiment can drive the clothes C to move along a circular path below the maximum radius Rmax of the water stirring member 200 by controlling the water stirring member 200 to rotate relative to the washing tub 100 for washing.

[0336] Specifically, at the bottom of the washing tub 100, the stirring action of the water flow by the water stirring member 200 creates a radial flow pattern around the washing tub 100, thereby driving the clothing C along the bottom of the washing tub 100 toward the center. Clothes C converging toward the center come into contact with the side surfaces of the water stirring member 200 and, due to the rotation of the water stirring member 200, are lifted upward along the second guide surface until they reach below the maximum radius Rmax of the water stirring member 200. Below the maximum radius Rmax of the water stirring member 200, the upward movement of the water flow and clothing C is blocked, causing them to move outward along the first guide surface formed by the maximum radius Rmax of the water stirring member 200. Finally, near the wall of the washing tub 100, or after contacting the wall, they descend back to the bottom of the washing tub 100 due to gravity and the water flow.

[0337] In this embodiment, the water-stirring member 200 installed within the washing tub 100 has a maximum radius Rmax formed at a certain distance from the tub bottom. A first guide surface extending outward from this location is also formed there. Below this maximum radius Rmax, a second guide surface connected to the first guide surface is also formed. During washing, a large portion of the bottom surface of the washing tub 100 is exposed to the wash water. Clothes C can be washed below the maximum radius Rmax of the water-stirring member 200, ensuring full contact and friction with the tub bottom 100 and the outer surface of the water-stirring member 200. This avoids the problem of blind spots between the water-stirring member 200 and the washing tub 100, where clothes C are difficult to reach and easily accumulate lint and dirt.

[0338] At the same time, the clothes C are washed along the bottom of the washing tub 100, the second guide surface, the first guide surface, and the wall of the washing tub 100, forming a circular path. That is, the clothes are collected at the bottom of the tub toward the center, then lifted to a certain height, and then move toward the periphery below the maximum radius Rmax of the water stirring member 200 before falling. This not only enhances the washing effect of the clothes C, but also effectively prevents the clothes C from getting entangled.

[0339] Example 8

[0340] As shown in FIG. 2 , FIG. 3 and FIG. 25 , this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly.

[0341] Specifically, the washing bucket assembly described in this embodiment includes a washing bucket 100, a water stirring member 200 and a stirring shaft 300 that drives the water stirring member 200 to rotate relative to the washing bucket 100. The bottom 100-3 of the washing bucket 100 has a mounting portion 100-2 rotatably assembled with the stirring shaft 300. The stirring shaft 300 passes through the mounting portion 100-2 and is connected to the water stirring member 200. The bottom of the water stirring member 200 is arranged opposite to the mounting portion 100-2. The radius of the bottom end face of the water stirring member 200 is equal to or substantially equal to the radius of the mounting portion 100-2. The inner surface of the bottom 100-3 of the mounting portion 100-2 extending outward to the inner circumferential wall of the washing bucket 100 is a washing surface 100-31 that can contact clothes.

[0342] The water-stirring member 200 and the washing tub 100 described in this embodiment have the above-mentioned matching structure. Compared with a traditional pulsator washing machine or an agitator washing machine with a radial agitator, the radius of the bottom end face of the water-stirring member 200 of this embodiment is small enough to achieve a connection between the water-stirring member 200 and the tub bottom 100-3 without an impeller, so that the washing tub has no bottom disc-shaped stirring portion, thereby exposing most of the area of ​​the tub bottom 100-3 to form a contact surface with the clothes, which can avoid the problem of dirt and grime easily accumulating between the stirring device and the tub bottom 100-3 of the existing washing equipment and being difficult to clean, and can prevent clothes from covering the impeller during washing, thereby reducing entanglement and wear on clothes and reducing energy consumption of the motor.

[0343] The mounting portion 100-2 of this embodiment is for the stirring shaft 300 to pass through and connect with the water-stirring member 200. Since the radius of the stirring shaft 300 is small enough, the mounting portion 100-2 is adapted to the stirring shaft 300. Therefore, the radius of the mounting portion 100-2 is also small enough. The radius of the bottom end face of the water-stirring member 200 is set to be equal to or substantially equal to the radius of the mounting portion 100-2. Then, the radius of the bottom end face of the water-stirring member 200 is small enough. In the prior art, the radius of the impeller set on the barrel bottom 100-3 is much larger than the radius of the mounting portion 100-2. Therefore, it can be considered that the barrel bottom 100-3 of this embodiment has no impeller, and there is no impeller connection between the water-stirring member 200 of this embodiment and the barrel bottom 100-3, so that most of the area of ​​the barrel bottom 100-3 is exposed to form a washing surface 100-31 that is in direct contact with the clothes, so that the washing surface 100-31 formed by the barrel bottom 100-3 is in contact with the clothes during washing, which can be distinguished from the direct contact between the clothes and the impeller during washing in the prior art.

[0344] It should be noted that the radii of the components involved in this embodiment are all radii along the radial direction of the washing tub 100. The tub bottom 100-3 includes a tub bottom body, and the mounting portion is provided on the tub bottom body, rather than providing a component on the tub bottom and the mounting portion on the component.

[0345] The radius of the bottom end surface of the water stirring member 200 is substantially equal to the radius of the mounting portion 100-2, including the radius of the bottom end surface of the water stirring member 200 being slightly larger than the radius of the mounting portion 100-2, or the radius of the bottom end surface of the water stirring member 200 being slightly smaller than the radius of the mounting portion 100-2;

[0346] Furthermore, the mounting portion 100-2 is a mounting through hole 100-21 provided on the bottom 100-3 of the barrel. The mounting through hole 100-21 can be circular, square, etc. The mounting through hole 100-21 passes through the bottom 100-3 of the barrel, and the water-stirring member 200 and the mounting through hole 100-21 are arranged relative to each other in the following manner: when the bottom end face of the water-stirring member 200 is equal to or greater than the radius of the mounting through hole 100-21, the bottom end face of the water-stirring member 200 is overlapped on the upper end face of the mounting through hole 100-21 and abuts against the upper end face of the mounting through hole 100-21; or, when the bottom end face of the water-stirring member 200 is smaller than the radius of the mounting through hole 100-21, the bottom end face of the water-stirring member 200 is inserted into the mounting through hole 100-21.

[0347] More specifically, the stirring shaft 300 extends from the mounting through-hole 100-21 to the interior of the washing tub 100, and the stirring shaft 300 is coaxially arranged with the washing tub 100. The water stirring member 200 of this embodiment includes an assembly portion 210-1 coaxially arranged with the tub bottom 100-3 and a water stirring portion 240 disposed above the assembly portion 210-1. The water stirring portion 240 is assembled with the stirring shaft 300 through the assembly portion 210-1.

[0348] The assembly part 210-1 of the water-stirring member 200 is sleeved on the upper end of the stirring shaft 300, and the assembly part 210-1 and the stirring shaft 300 are key-connected. The assembly part 210-1 and the stirring shaft 300 are circumferentially positioned by splines. Preferably, the assembly part 210-1 of the water-stirring member 200 and the stirring shaft 300 are axially positioned by a clamping structure or screws.

[0349] Mounting portion 210-1 corresponds to mounting hole 100-21 in the center of tub bottom 100-3. A mounting groove 100-1 is provided inside tub bottom 100-3, and the lower end of mounting portion 210-1 rotatably extends into mounting groove 100-1. Mounting groove 100-1 is positioned around agitator shaft 300, and mounting hole 100-21 is provided at the bottom of mounting groove 100-1. Agitator shaft 300 passes through mounting groove 100-1 and extends into the interior of washing tub 100. The radius of the bottom of mounting portion 210-1 matches the radius of mounting groove 100-1.

[0350] Washing surface 100-31 and the space above washing surface 100-31 form a washing space. Water agitating member 200 has a maximum radius at a certain distance from washing surface 100-31. Clothes can be washed in the washing space below the maximum radius of water agitating member 200, or they can be guided from below the maximum radius of water agitating member 200 to the washing space above for washing. Water agitating member 200 decreases in size after its maximum radius. The washing space below the maximum radius of water agitating member 200 forms a first space 100a, while the space between the maximum radius of water agitating member 200 and the minimum radius above it forms a second space 100b.

[0351] The minimum radius above the maximum radius of the water stirring member 200 is at a certain distance from the barrel opening of the washing tub 100, and the washing space between the minimum radius above the maximum radius of the water stirring member 200 and the barrel opening forms a third space 100c;

[0352] When the water level in the washing tub is higher than a set water level, the water stirring member rotates to guide part of the clothes from the first space and the second space to the third space for washing.

[0353] At the lowest water level, laundry can be washed in the first space 100a and the second space 100b, and at the highest water level, laundry can be washed in the first space 100a, the second space 100b, and the third space 100c.

[0354] Specifically, the washing tub assembly of this embodiment is applied to a washing device. As shown in FIG17 , when operating at a low water level W1 lower than the maximum radius Rmax of the water stirring member 200 , the clothes move along a reverse circular path in the water.

[0355] In detail, during the washing process, relative rotation occurs between the water-stirring member 200 and the washing tub 100, and the clothes move along the path indicated by the arrow in the figure in the first space 100a below the maximum radius Rmax of the water-stirring member 200, move toward the central area along the bottom 100-3 of the washing tub 100, and then are lifted to the bottom of the first guide surface 213 along the water-stirring ribs 220, and then move toward the periphery along the first guide surface 213, and then fall to the bottom 100-3 of the washing tub 100 in the area close to the wall of the washing tub 100, forming a circular motion.

[0356] As shown in Figure 18, when operating at a high water level W2 that is higher than the maximum radius Rmax of the water-stirring member 200, in an area lower than the maximum radius Rmax of the water-stirring member 200, the clothes move along the above-mentioned circular path in the water; and in an area at the minimum radius above the maximum radius of the water-stirring member 200, the clothes move close to the circumferential direction of the washing tub 100, that is, the clothes are washed in the third space 100c.

[0357] Specifically, during the washing process, the agitating member 200 rotates relative to the washing tub 100. Within the area below the maximum radius Rmax of the agitating member 200, the clothing moves along a path substantially consistent with the path taken at low water level W1. Within the area above the minimum radius Rmax of the agitating member 200, the clothing moves along the circumference of the washing tub 100100 in alternating forward and reverse rotation of the agitating member 200.

[0358] In the above scheme, when different washing water levels are used, the water stirring member 200 can drive the clothes in the barrel to move in different ways for washing, providing a more diverse selection of washing methods. Moreover, in the area below the maximum radius Rmax of the water stirring member 200, since the clothes move along a reverse circular path, on the one hand, the tumbling of the clothes can be enhanced, thereby enhancing the washing effect, and on the other hand, it avoids the problem that the existing pulsator washing machine easily drives the clothes to gather towards the center, causing the clothes to become entangled. It should be noted that the upper end of the water stirring rib 220 is connected to the first guide surface 213, and the first guide surface 213 in the first embodiment can be formed on the water stirring rib 220.

[0359] In this embodiment, the water-stirring component 200 includes an assembly portion 210-1 coaxially arranged with the barrel bottom 100-3 and a water-stirring component 240 arranged above the assembly portion 210-1. The stirring shaft 300 is inserted into the assembly portion 210-1 through the installation portion 100-2 and connected to the water-stirring component 240. The water-stirring component 200 has a maximum radius at a certain distance from the inner surface of the washing barrel 100. The radius of the assembly portion 210-1 is the minimum radius of the water-stirring component 200 below the maximum radius of the water-stirring component 200.

[0360] In this embodiment, the assembly portion 210-1 of this embodiment is the assembly portion 210-1, and the assembly portion 210-1 can be cylindrical, and can be a cylindrical shape with a radius that changes from top to bottom, or can be a cylindrical shape with a constant radius from top to bottom; wherein, the assembly portion 210-1 has a cavity inside for inserting the stirring shaft 300;

[0361] In this embodiment, the radius of the water-stirring member 200 has the same meaning as in the sixth embodiment.

[0362] Below the maximum radius of the water-stirring member 200, the radius of the assembly part 210-1 is the minimum radius of the water-stirring member 200, so that the radius of the assembly part 210-1 is small enough to achieve a pulsator-free connection between the water-stirring member 200 and the barrel bottom 100-3, thereby exposing most of the area of ​​the barrel bottom 100-3 to form a washing surface 100-31 that contacts the clothes.

[0363] In this embodiment, the water stirring portion 240 includes a support column 210 coaxial with the assembly portion 210-1 and a water stirring rib 220 protruding from the side wall of the support column 210. The maximum radius of the water stirring member 200 is set on the support column 210, and the radius of the support column 210 below the maximum radius of the water stirring member 200 is greater than or equal to the radius of the assembly portion 210-1.

[0364] In this embodiment, the support column 210 can be cylindrical. Specifically, as shown in FIG2 and FIG12 to FIG16 , the support column 210 can be cylindrical with a constant radius from bottom to top. The radius of the support column 210 is set to be greater than or equal to the radius of the assembly portion 210-1, so that the radius of the assembly portion 210-1 can be sufficiently small. Preferably, the assembly portion 210-1 and the support column 210 are integrally formed.

[0365] Specifically, the position where the maximum radius of the water-stirring member 200 is located at the support column 210 of the water-stirring member 200 includes the position where the maximum radius of the water-stirring member 200 is located at the top of the support column 210 of the water-stirring member 200; or, the position where the maximum radius of the water-stirring member 200 is located at the top of the support column 210 of the water-stirring member 200 is spaced apart from the top of the support column 210 of the water-stirring member 200.

[0366] As a specific embodiment, as shown in Figures 2 and 12 to 14, the water stirring member 200 has a single maximum radius Rmax in the height direction. Furthermore, at least below the maximum radius Rmax, the distance between the side surface of the water stirring member 200 and the inner peripheral wall of the washing tub 100 decreases as the height increases.

[0367] It should be noted that the single maximum radius Rmax may refer to the water-stirring member 200 having the maximum radius Rmax at a specific height position, or may refer to the water-stirring member 200 having the maximum radius Rmax within a certain continuous height range.

[0368] In a first specific solution, as shown in FIG12 , the maximum radius Rmax of the water-stirring member 200 is set at the top of the water-stirring member 200 , that is, the top surface of the water-stirring member 200 is the cross-section with the largest radius.

[0369] In a second embodiment, as shown in FIG2 , the maximum radius Rmax of the agitating member 200 is close to the top of the agitating member 200 but is a certain distance away from the top of the agitating member 200. Specifically, the upper surface of the agitating member 200 at the maximum radius Rmax is an upwardly convex curved surface, with the highest point of the curved surface forming the top of the agitating member 200.

[0370] In the third specific solution, as shown in FIG. 13 and FIG. 14 , the maximum radius Rmax of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0371] In one detailed embodiment, as shown in FIG13 , the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 continuously changes in height. Specifically, as the height increases, the radius of the water-stirring member 200 gradually increases from the bottom 100 - 3 of the washing tub 100 upward, until reaching the maximum radius Rmax. Thereafter, the radius of the water-stirring member 200 gradually decreases, ultimately reaching the top of the water-stirring member 200.

[0372] In another detailed embodiment, as shown in Figure 14, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 changes abruptly at at least one height. Specifically, as the height increases, the radius of the water-stirring member 200 gradually increases from the bottom 100-3 of the washing tub 100 upward. At a certain height, the radius suddenly increases, forming the maximum radius Rmax. The radius of the water-stirring member 200 then remains constant within a certain height range before suddenly decreasing, and then continues to gradually decrease, ultimately forming the top of the water-stirring member 200. In this embodiment, the distance h from the maximum radius Rmax on the water-stirring member 200 to the bottom 100-3 of the washing tub 100 refers to the distance from the lowest height within the height range where the radius of the water-stirring member 200 remains constant to the bottom 100-3 of the washing tub 100.

[0373] The maximum radius of the agitating member 200 is located at the support column 210 of the agitating member 200 , and also includes a plurality of maximum radius locations of the support column 210 of the agitating member 200 distributed at intervals from top to bottom.

[0374] As another specific embodiment, as shown in FIG16 , the water-stirring member 200 has a plurality of maximum radii Rmax spaced apart along the axis of the washing tub 100. Specifically, as the height increases, the radius of the water-stirring member 200 alternately increases and decreases, each time increasing to the same radius and then decreasing, thereby forming a plurality of maximum radii Rmax spaced apart.

[0375] Furthermore, in this embodiment, the axial length of the assembly part 210-1 is set to be smaller than the axial length of the support column 210. As the above-mentioned axial direction is the axial direction of the washing barrel 100, the axial length of the assembly part 210-1 is much smaller than the axial length of the support column 210, which can reduce the axial thickness of the assembly part 210-1, so that a larger area of ​​the barrel bottom 100-3 can be exposed.

[0376] In this embodiment, the water-stirring rib 220 has a certain extension length along the axial direction of the support column 210, and the bottom end of the water-stirring rib 220 is connected to the assembly part 210-1 located in the washing tub 100. The position where the water-stirring rib 220 is connected to the assembly part 210-1 is separated from the bottom 100-3 of the tub by the side wall of the assembly part 210-1, which can prevent dirt and grime from easily accumulating between the water-stirring rib 220 and the bottom 100-3 of the tub, and makes the bottom of the washing space formed by the side wall of the assembly part 210-1, the mounting part 100-2 extending outward to the inner surface of the bottom 100-3 of the inner peripheral wall of the washing tub 100, and the water-stirring rib 220 and the inner peripheral wall of the washing tub be large enough.

[0377] Alternatively, the bottom end of the water-stirring rib 220 is connected to the bottom end of the side wall of the assembly part 210-1 located in the washing tub 100, so that the mounting part 100-2 extends outward to the inner side surface of the barrel bottom 100-3 of the inner peripheral wall of the washing tub 100, and the water-stirring rib 220 and the inner peripheral wall of the washing tub 100 form a washing space; when the assembly part 210 is entirely in the washing tub, the bottom end of the water-stirring rib 220 is connected to the bottom end of the side wall of the assembly part 210-1, and when the first part of the assembly part 210 is in the washing tub, the bottom end of the water-stirring rib 220 is connected to the bottom end of at least part of the side wall of the assembly part 210.

[0378] In this embodiment, the lower end of the water-stirring rib 220 is spaced apart from the bottom 100-3 of the washing tub 100. The top end of the water-stirring rib 220 extends to the maximum radius of the water-stirring member 200. Preferably, the top end of the water-stirring rib 220 extends to the outer peripheral edge of the maximum radius of the water-stirring member 200. Specifically, the bottom of the support column 210 has a mounting portion 210-1 for connecting to the stirring shaft 300. The outer peripheral edge of the water-stirring rib 220 extends upwardly from a point on the side wall of the support column 210 at a predetermined distance from the upper end of the mounting portion 210-1. The inclination angle remains constant or gradually changes, ultimately extending to the height of the maximum radius Rmax of the water-stirring member 200. No other structure extending radially along the washing tub 100 exists between the lower end of the water-stirring rib 220 and the mounting portion 210-1. The water-stirring rib 220 does not cover the bottom 100-3 of the washing tub 100, ensuring that there is essentially no area of ​​the bottom 100-3 of the washing tub 100 that is inaccessible to clothing.

[0379] As the agitating member 200 rotates within the washing tub 100, the agitating ribs 220 agitate the clothes C and the water flow within the tub. The rotation of the agitating member 200 can generate various water flows to move the clothes C for washing. Specifically, below the maximum radius Rmax of the agitating member 200, the clothes C move along a circular path within the formed washing space for washing. The aforementioned circular path refers to the movement of the clothes C from the bottom 100-3 of the washing tub 100 toward the center, where they are lifted by the agitating member 200 to a position near the maximum radius Rmax of the agitating member 200, then move toward the periphery before falling. Specifically, the clothes move toward the center of the bottom 100-3 of the washing tub 100, where they are lifted along the sidewalls of the support column 210 or the outer edges of the agitating ribs 220 to below the maximum radius Rmax. They then move toward the periphery before falling to the bottom 100-3 near the wall of the washing tub 100, forming a circular motion.

[0380] Furthermore, the protrusion direction of the water-stirring rib 220 on the side wall of the support column 210 coincides with the radial direction of the washing tub 100, or forms an angle less than 90° with the radial direction of the washing tub 100. In this way, when the water-stirring rib 220 rotates with the water-stirring member 200, the surface of the water-stirring rib 220 is arranged opposite to the direction of rotation, which can achieve an effective stirring effect.

[0381] More specifically, a plurality of agitating ribs 220 are circumferentially spaced apart on the sidewall of the support column 210. The agitating ribs 220 are preferably symmetrically arranged relative to the axis of rotation. Clothes C can be washed in the space between two adjacent agitating ribs 220, thereby contacting both side surfaces of the agitating ribs 220 and the area between the two agitating ribs 220 on the sidewall of the support column 210, thereby avoiding the presence of blind spots on the sidewall of the support column 210 where dirt easily accumulates. Simultaneously, during washing, clothes C moving toward the center along the bottom 100-3 of the washing tub 100 are lifted along the sidewall of the support column 210 to below the maximum radius Rmax of the agitating member 200, then move toward the periphery before falling, forming a circular path.

[0382] Below the maximum radius Rmax of the water-stirring member 200, the sidewall of the support column 210 extends vertically or nearly vertically until it reaches the maximum radius Rmax of the water-stirring member 200. A water-stirring rib 220 protrudes from the sidewall of the support column 210 and extends a certain height along the axial direction of the washing tub 100. The radial dimension of the water-stirring rib 220 increases with increasing height of the washing tub 100, thereby forming a structure in which the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 decreases with increasing height.

[0383] Specifically, the sidewall of the mounting portion 210-1 is parallel or substantially parallel to the inner circumferential wall of the washing tub. The spacing between the water stirring rib 220 and the inner surface of the tub bottom 100-3 gradually increases from its lowest end toward the inner circumferential wall of the washing tub. Furthermore, the water stirring rib 220 has an arcuate outer surface that bulges outward relative to the axis of the support column 210. The radial spacing between the arcuate outer surface and the axis of the support column 210 gradually increases from the lowest end of the water stirring rib 220 upward, further exposing a larger area of ​​the tub bottom 100-3. This arcuate outer surface reduces wear on clothing.

[0384] As a specific implementation, in this embodiment, the distance h between the maximum radius Rmax of the water stirring member 200 and the barrel bottom 100-3 is greater than 5 mm, thereby ensuring that the clothes C can be washed below the maximum radius Rmax.

[0385] Furthermore, in this embodiment, the depth of the washing tub 100 is H, and the relationship between the distance h and the depth H of the washing tub 100 satisfies the following relationship: h / H ≥ 1%. Extensive prior testing has revealed that when the distance h and the depth H of the washing tub 100 satisfy this proportional relationship, the best effect of preventing dirt and grime from accumulating between the water-stirring member 200 and the washing tub 100 is achieved.

[0386] In a further solution of this embodiment, there is also a certain distance in height between the maximum radius Rmax of the water-stirring member 200 and the barrel mouth of the washing barrel 100, so that the washing water level can be higher than the maximum radius Rmax of the water-stirring member 200, so that the clothes C can be washed above the position of the maximum radius Rmax of the water-stirring member 200.

[0387] In the above scheme, the washing tub 100 can accommodate clothes C for washing both above and below the maximum radius Rmax of the water-stirring member 200. On the one hand, the volume of the washing tub 100 that can accommodate clothes C is increased. On the other hand, the outer surface of the water-stirring member 200 can basically contact the clothes C to be washed, generating friction with the clothes C. By increasing the surface area in contact with the clothes C, the washing effect can be enhanced.

[0388] Regarding the solution in which the maximum radius Rmax of the water-stirring member 200 is located at or close to the top of the water-stirring member 200, as a specific implementation, as shown in Figure 12, the maximum radius Rmax of the water-stirring member 200 is formed by the upper end of the outer peripheral edge of the water-stirring rib 220.

[0389] As another specific embodiment, as shown in FIG2 , the water stirring member 200 further includes a water stirring pan 230 connected to the upper end of the support column 210. The outer periphery of the water stirring pan 230 defines the maximum radius Rmax of the water stirring member 200. The upper end of the water stirring rib 220 is connected to the lower surface of the water stirring pan 230, thereby preventing the formation of a dead corner between the water stirring rib 220 and the water stirring pan 230, which is inaccessible to clothing C and easily harbors dirt.

[0390] Furthermore, the water-stirring member 200 of this embodiment forms a guide surface extending toward the periphery below the maximum radius Rmax. During washing, the clothes C lifted to below the maximum radius Rmax of the water-stirring member 200 move toward the periphery along the guide surface. More specifically, in this embodiment, the guide surface includes the lower surface of the water-stirring plate 230. Preferably, a smoothly transitioning curved surface is provided between the upper end of the side wall of the support column 210 and the lower surface of the water-stirring plate 230. More preferably, a rounded transition is provided between the two side surfaces of the water-stirring rib 220 and the lower surface of the water-stirring plate 230. In this way, the dead corners on the water-stirring member 200 that are difficult to clean are further reduced.

[0391] As a specific solution, in this embodiment, the upper end of the water-stirring rib 220 is aligned with the outer periphery of the water-stirring plate 230 away from the support column 210, so that the radial dimension of the water-stirring rib 220 along the washing tub 100 is maximized as much as possible, thereby enhancing the agitation of the washing water and improving the washing effect.

[0392] When washing clothes C, the washing device having the washing tub assembly described in this embodiment can drive the clothes C to move along a circular path below the maximum radius Rmax of the water stirring member 200 by controlling the water stirring member 200 to rotate relative to the washing tub 100 for washing.

[0393] Specifically, at the bottom of the washing tub 100, the stirring action of the water flow by the water stirring member 200 creates a radial flow pattern within the washing tub 100, thereby driving the clothing C along the bottom 100-3 of the washing tub 100 toward the center. Clothes C converging toward the center come into contact with the side surfaces of the water stirring member 200 and, due to the rotation of the water stirring member 200, are lifted upward until they reach below the maximum radius Rmax of the water stirring member 200. Below the maximum radius Rmax of the water stirring member 200, the upward movement of the water flow and clothing C is blocked, causing them to move outward along the guiding surface below the maximum radius Rmax of the water stirring member 200. Ultimately, near the wall of the washing tub 100, or after contacting the wall, they descend back to the bottom 100-3 due to gravity and the water flow.

[0394] In this embodiment, the water-stirring member 200 installed in the washing tub 100 forms a maximum radius Rmax at a certain distance from the tub bottom 100-3, allowing the clothes C to be washed below the maximum radius Rmax. This allows the majority of the surface of the tub bottom 100-3 of the washing tub 100 to be exposed to the wash water and come into contact with the clothes C. During the washing process, the clothes C can come into contact with the tub bottom 100-3 of the washing tub 100 and the outer surface of the water-stirring member 200 located below the maximum radius Rmax, generating friction. This effectively avoids the problem of a blind spot between the water-stirring member 200 and the washing tub 100, which can easily accumulate lint and dirt.

[0395] On the other hand, during the washing process, the water-stirring component 200 can drive the clothes C to gather towards the center at the bottom of the barrel 100-3, then be lifted to a certain height, and then guide the clothes C to move toward the periphery and then fall, thereby moving along a reverse circular path around the water-stirring component 200, which can not only enhance the washing effect, but also prevent the clothes C from getting entangled.

[0396] Example 9

[0397] As shown in FIG. 2 and FIG. 3 , this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly.

[0398] Specifically, the washing tub 100 assembly includes a washing tub 100 and a water stirring member 200 rotatably arranged inside the washing tub 100. The water stirring member 200 extends upward from the bottom of the washing tub 100 and has a maximum radius Rmax at a certain extension height. There is a distance between the maximum radius Rmax and the inner surface of the bottom of the tub constituting the washing space, and the height value of the distance is greater than a preset value.

[0399] More specifically, 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.

[0400] In the above scheme, there is a gap between the maximum radius Rmax of the water-stirring component 200 and the bottom of the barrel 100-3 for washing clothes, and the height value of the gap is greater than the preset value, so that water can enter the gap to flush out stains, avoiding the problem of dirt and grime hiding between the water-stirring component 200 and the bottom of the barrel 100-3, and improving the user experience.

[0401] In this embodiment, the water-stirring member 200 is provided in the washing tub 100, extending upward from the bottom of the washing tub 100 along its axial direction. The water-stirring member 200 has a maximum radius Rmax at one of its extended heights. There is a distance between the maximum radius Rmax and the inner surface of the bottom of the washing tub 100 constituting the washing space, 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 a preset value, the clothes C to be washed can be washed within the distance, avoiding the accumulation of dirt and grime in the distance. In existing washing machines, a dial is provided in the washing tub, and the washing space in the washing machine refers to the area above the dial. However, the washing tub of the washing machine in this solution does not have a dial, and an upwardly extending water-stirring member is provided at the bottom of the washing tub. The washing space in this solution refers to the area between the outer periphery of the water-stirring member and the inner peripheral wall of the washing tub.

[0402] It should be noted that in this embodiment, the radius of the agitating member 200 refers to the radius of a circle centered at the rotation center at the point of greatest distance from the rotation center on a cross section of the agitating member 200 taken perpendicular to its rotation axis. Alternatively, this is similar to the definition of "radius of the horizontal cross section of the agitating portion 240" in the first embodiment.

[0403] In this embodiment, no pulsator is provided at the bottom of the washing tub 100 , and the clothes C to be washed directly come into contact with the inner surface of the bottom of the washing tub 100 .

[0404] Since there is no impeller at the bottom of the washing tub 100 and a gap is provided between the maximum radius Rmax and the inner surface of the bottom of the washing tub 100, water flow can flush the gap during the washing process of the clothes C, thereby preventing dirt from accumulating between the water stirring member 200 and the bottom of the washing tub 100.

[0405] The solution of this embodiment also includes: the preset value is 10 cm. That is, the distance between the maximum radius 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 sufficient washing space.

[0406] More specifically, the washing tub includes a tub bottom 100-3 disposed at the bottom and a tub body 100-4 disposed above the tub bottom. The water stirring member has a maximum radius disposed above the highest point of the tub bottom 100-3. In other words, the maximum radius is disposed in the tub body 100-4 and is a certain distance away from the highest point of the tub bottom 100-3.

[0407] The solution of this embodiment also includes: the water-stirring component 200 includes an assembly part 210-1 coaxially arranged with the bottom of the barrel and a water-stirring part 240 arranged above the assembly part 210-1, and the assembly part 210-1 cooperates with the bottom of the barrel; the water-stirring part 240 has a support column 210 and a water-stirring rib 220 arranged on the support column 210 along the extension direction of the support column, and the water-stirring rib 220 extends toward the peripheral wall of the washing barrel 100; the support column 210 extends upward from the top of the assembly part 210-1, and the radius of the connection between the support column 210 and the assembly part 210-1 is similar; the maximum radius Rmax is at a distance from the top of the assembly part 210-1.

[0408] The center of the washing tub 100 is recessed to form a mounting groove 250. The mounting portion 210-1 is positioned within the groove, with its upper end protruding from the groove 250, either above or flush with the inner surface of the tub bottom. A mounting hole is defined in the bottom of the groove, through which the agitator shaft passes, inserts into the mounting portion 210-1, and connects to the water stirring portion 240. The support column 210 and the mounting portion 210-1 have the same radius at their connection, and the two are integrally formed.

[0409] The water stirring portion 240 further includes a water stirring pan 230, which is mounted above the water stirring ribs 220 and at the extended end of the water stirring member 200. The water stirring pan 230 has an extended height along the central axis of the washing tub 100, and the maximum radius Rmax is located at any extended height of the water stirring pan 230.

[0410] The water stirring rib 220 first extends obliquely toward the edge of the washing tub 100 opening, and then extends upward toward the opening parallel to the support column 210. The length of the maximum radius Rmax does not exceed the radius of the washing tub.

[0411] In the solution of this embodiment, the water stirring member 200 includes an assembly portion 210-1 coaxially arranged with the bottom of the barrel and a water stirring portion 240 arranged above the assembly portion 210-1. The water stirring portion 240 includes a support column 210 coaxially arranged with the bottom of the barrel, a water stirring rib 220 arranged on the outer periphery of the support column 210, and a water stirring tray 230 arranged at the end of the support column 210. In other words, one end of the support column 210 is connected to the top of the assembly portion 210-1, and the other end extends upward. The water stirring tray 230 is provided at its extended end. The water stirring rib 220 extends obliquely from the outer periphery of the connection between the support column 210 and the assembly portion 210-1 toward the top of the washing tub 100.

[0412] The support column 210 is cylindrical and is coaxially arranged with the assembly portion 210 - 1 , and 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 .

[0413] In one specific embodiment of this invention, the assembly portion 210-1 and the support column 210 have the same radius at their connection, and the two are integrally formed. Of course, in other embodiments of this invention, the assembly portion 210-1 can be shaped other than cylindrical, and its inner diameter can be slightly larger than the inner diameter of the support column 210, all of which are within the scope of protection of the present invention.

[0414] In a specific embodiment of this embodiment, the support column 210 is a cylindrical structure with a uniform radius along its extension. The support column 210 extends upward from the top of the mounting portion 210-1, and a water stirring tray 230 is provided at the distal end of the extension. In this embodiment, the maximum radius Rmax is located on the water stirring tray 230.

[0415] In another embodiment of the present invention, 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 inner diameters of the first and second extension sections 211 and 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. The provision of the first and second extension sections 211 and 212 significantly increases the angle between the sidewall of the upper end of the support column 210 and the lower surface of the water agitation tray 230, thereby effectively reducing the problem of a blind spot between the upper end of the support column 210 and the lower surface of the water agitation tray 230, where clothing C cannot reach. In this solution, the contact area between the end cap and the support column 210 is increased, making the two more firmly fixed. In this solution, the assembly portion 210-1, the first extension section 211 and the second extension section 212 are integrally formed, and the assembly portion 210-1 and the first extension section 211 have the same radius.

[0416] The washing machine is equipped with a drive device, on which an agitator shaft is mounted. A mounting hole is provided in the bottom of the washing tub 100, extending through the bottom. The agitator shaft of the drive device is inserted through the mounting hole into the interior of the mounting portion 210-1 and connected to the water stirring unit 240. When the washing machine is performing a washing operation, the agitator shaft drives the mounting portion, thereby rotating the water stirring unit 240.

[0417] In one solution of this embodiment, the bottom of the washing tub has a downwardly extending mounting groove, and a mounting through-hole is provided on the bottom surface of the mounting groove. The agitator shaft of the driving device is connected to the water stirring portion 240 by being inserted through the mounting through-hole into the assembly portion 210-1 vertically disposed in the mounting groove. The upper end of the assembly portion 210-1 is flush with the inner surface of the tub bottom. That is, in this solution, 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 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 tub bottom.

[0418] As shown in Figures 19 to 22, in another embodiment of the present invention, the bottom of the washing tub is substantially flush with the horizontal plane. The center of the bottom of the washing tub is recessed downward to form a mounting groove 100-1. A mounting hole 100-21 is provided in the bottom surface of the mounting groove 100-1. The agitator shaft of the driving device is inserted through the mounting hole 100-21 into a mounting portion 210-1 vertically disposed in the mounting groove, thereby connecting to the water stirring portion 240. The mounting portion 210-1 is vertically disposed and protrudes from the mounting groove 100-1, 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 in the mounting groove 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 mounting groove 100-1 is slightly larger than the radius of the mounting portion. More specifically, the radius of the mounting groove 100-1 is slightly larger than the radius of the mounting portion, i.e., the radius of the first portion, which is disposed within the mounting groove.

[0419] 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.

[0420] 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.

[0421] Of course, in other solutions of this embodiment, the bottom of the washing tub may not have a mounting groove, but may instead have a mounting hole formed directly on the surface of the bottom, with the assembly portion protruding directly from the inner surface of the bottom. In other words, the lower end of the support rib is spaced a certain distance from the inner surface.

[0422] 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 .

[0423] It is worth noting that the extension length of the water-stirring rib 220 is different at different height positions of the support column 210. In other words, the outer contour of the water-stirring rib 220 is an arc.

[0424] 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.

[0425] 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.

[0426] For example, the radial dimension of the water-stirring ribs 220 along the washing tub 100 increases first and then decreases from the lower end to the upper end. In this solution, the number of the water-stirring ribs can be set as required.

[0427] In this embodiment, the radius of any horizontal cross-section of the agitating portion 240 specifically refers to the distance from the center axis to the point at which the agitating rib 220 is furthest from the axis on that horizontal cross-section. When the number of agitating ribs 220 is even, the length of the line connecting the furthest points of two opposing agitating ribs 220 from the axis is the diameter of the horizontal cross-section of the agitating portion 240. When the number of agitating ribs 220 is odd, there are no opposing agitating ribs 220. In this case, the horizontal cross-section of the agitating portion 240 does not form an axisymmetric shape, but the diameter of the horizontal cross-section of the agitating portion 240 remains twice the radius determined above.

[0428] 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.

[0429] 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.

[0430] 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 Rmax is located on the water stirring tray 230 .

[0431] In one embodiment of this invention, the agitating ribs 220 are umbrella-shaped, with the support column 210 serving as the handle and the agitating pan 230 serving as the canopy. In this agitating member 200, the radius of the agitating pan 230 decreases from bottom to top, with the maximum radius Rmax located at the bottom of the pan 230. Because the agitating ribs 220 are spaced apart circumferentially around the support column 210, their top ends are positioned below the pan 230.

[0432] The upper surface of the water stirring tray 230 is a curved surface with a middle area higher than the outer peripheral area. In order to further increase the contact area between the water stirring member 200 and the clothes C to be washed, a raised stirring portion 231 is provided on the curved surface.

[0433] As shown in Figure 20, 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 garments C 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 garments C rub against the surfaces of the multiple stirring portions 231, resulting in a cleaner wash.

[0434] 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 .

[0435] It is worth noting that, in this solution, the distance between the outermost periphery of the water-stirring rib 220 and the mounting column is smaller than the radius Rmax of the maximum radius of the water-stirring plate 230 .

[0436] In this embodiment, the maximum radius Rmax can be set at any height position along the height 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 Rmax can be set in any of these areas. In other words, the radius of the end cap can gradually decrease, increase, or first increase and then decrease along the height of the water stirring tray 230.

[0437] 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 rib 220, and the other part is a conical structure with a gradually decreasing inner diameter at the end of the cylindrical structure. In this embodiment, the maximum radius Rmax is still located in the lower area of ​​the water-stirring pan 230.

[0438] For example, as shown in FIG2 , the water stirring plate 230 is a disc-shaped structure disposed above the water stirring rib.

[0439] For example, the water stirring pan 230 is a structure in which the radius gradually increases and then gradually decreases from bottom to top. In this solution, the maximum radius Rmax is equivalent to the middle area of ​​the water stirring pan 230.

[0440] For example, as shown in Figure 14, the water stirring pan 230 is composed of two parts. One part is a truncated cone-shaped structure that abuts the water stirring rib 220 and extends upward. The other part is a conical structure with a gradually decreasing inner diameter at the end of the truncated cone. In this embodiment, the maximum radius Rmax is still located in the lower area of ​​the water stirring pan 230.

[0441] The water stirring tray may also be in an irregular shape as shown in FIG13 .

[0442] 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.

[0443] Of course, since the water stirring tray 230 has a certain thickness, the cross-sectional shapes at different thickness positions may be different.

[0444] The solution of this embodiment also includes: the projection of any position of the outer edge of the water stirring rib 220 perpendicular to the barrel bottom is directly located on the inner surface of the barrel bottom of the washing barrel 100.

[0445] With the vertical distance between any position on the outer edge of the water-stirring rib 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 the circle vertically to the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0446] The projection of any position of the maximum radius Rmax vertically toward the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0447] In this embodiment, the outer edge of the water-stirring rib 220 is curved, and its projection perpendicular to the bottom of the tub from any position directly and unobstructedly rests on the inner surface of the bottom of the washing tub 100. The outer edge of the water-stirring rib 220 extends perpendicularly downward to the inner tub bottom at any position, contacting the inner surface of the inner tub bottom. In other words, no dial is provided in the linear area between the projection perpendicular to the bottom of the edge of the water-stirring rib 220 at its maximum radius and the outer perimeter of the support column 210. In this embodiment, there is no bottom disc-shaped stirring portion.

[0448] Since the water-stirring ribs 220 in this embodiment are arranged at circumferential intervals along the support column 210, a circle is drawn with the vertical distance between any position on the outer edge of the water-stirring rib 220 and the support column 210 as the radius and the axis of the support column parallel to the outer edge as the center. 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.

[0449] 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.

[0450] Similarly, the circular area formed by the edge of the maximum radius Rmax on the water stirring plate 230, 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.

[0451] 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 Rmax 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.

[0452] 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.

[0453] In this solution, in order to ensure the washing space for the clothes C, the maximum radius Rmax on the water stirring tray 230 cannot be too large. Specifically, the length of the maximum radius Rmax can be set to not exceed the radius length of the washing tub.

[0454] The solution provided by this embodiment, by providing the water stirring member 200 in the washing tub 100, can not only prevent dirt and grime from accumulating between the water stirring member 200 and the tub bottom, thus improving the user experience, but also save energy.

[0455] Example 10

[0456] As shown in Figures 19 to 22, this embodiment provides a washing tub assembly for washing equipment, and a washing equipment having the same. The washing tub assembly provided in this embodiment differs from the sixth to ninth embodiments described above in that the distance between the sidewall of the support column 210 and the tub wall of the washing tub 100 decreases with increasing height below the maximum radius Rmax of the water-stirring member 200.

[0457] Specifically, in this embodiment, a raised water-stirring rib 220 is provided on the sidewall of the support column 210. The radial dimension of the water-stirring rib 220 along the washing tub 100 can remain constant as the height increases, or it can change gradually or stepwise. Because the distance between the sidewall of the support column 210 and the wall of the washing tub 100 decreases with increasing height, the distance between the side of the water-stirring member 200 and the wall of the washing tub 100 decreases with increasing height. Similar to the previous embodiment, clothes can also be washed within the space formed by the bottom of the washing tub 100, the sidewall of the support column 210, and the wall of the washing tub 100.

[0458] More specifically, the specific structures of the support column 210 and the water-stirring rib 220 of the water-stirring member 200 may be the specific structures in the above-mentioned embodiment 2, which will not be described in detail here.

[0459] Furthermore, in this embodiment, the further specific structure of the water stirring member 200 can adopt the solution in the above embodiment three, and the specific assembly relationship between the water stirring member 200 and the stirring shaft 300 and the barrel bottom 100-3 can adopt the solution in the above embodiment three or four.

[0460] 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.
