Description

Technical Field

[0001] The 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 which pulsator washing machines are popular with users due to their good washing effect.

[0003] A pulsator washing machine usually includes a washing inner barrel and a pulsator, and the pulsator is arranged at the bottom of the washing inner barrel. When the pulsator washing machine is working, the rotation of the pulsator drives the washing water in the inner barrel to rotate, so as to wash the clothes to be washed in the inner barrel. The existing pulsator is usually a flat circular pulsator. When washing, impurities such as dirt and lint on the clothes are easily accumulated in the gap between the bottom surface of the pulsator and the inner barrel, and cannot be effectively cleaned by simply flushing. In addition, dirt and lint are easy to breed bacteria 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 more complicated, which further deteriorates the user experience.

[0004] In the prior art, a stirring type washing machine is also proposed, which uses an agitator with a certain size along the axial direction of the washing inner barrel to replace the pulsator in the pulsator washing machine. Figure 1 As shown, the agitator 1 in the existing agitator washing machine is often in an "inverted T" shape, consisting of an axial agitator 2 and a radial agitator 3, wherein the radial agitator 3 is arranged at the bottom of the washing tub 4 and has a larger radial dimension, and the clothes Y can only be washed in the area above the radial agitator 3 in the tub, which still cannot solve the problem that the gap between the agitator 1 and the bottom of the tub is easy to hide dirt and is difficult to clean. Some other agitator washing machines directly install the columnar agitator rod on the impeller at the bottom of the tub, and dirt and bacteria are still easy to accumulate between the impeller and the bottom of the tub.

[0005] On the other hand, for washing machines with a bottom impeller, the clothes cover a large area on the impeller surface during washing. The friction between the impeller and the clothes drives the clothes to move in the washing water, which increases the entanglement and wear of the clothes. At the same time, the friction between the clothes and the impeller will also increase the energy consumption required by the drive motor to drive the impeller to rotate.

[0006] Meanwhile, the existing impeller or agitator stirs the washing water more strongly in the bottom area of ​​the washing tub, thus achieving a better washing effect when washing at a low water level. However, when washing at a high water level, the washing water in the upper area of ​​the tub is less stirred, and the impact force of the water flow is relatively small, which cannot achieve a good washing effect in the upper area of ​​the tub.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing barrel assembly of a washing device and a washing device, which can enhance the washing effect and avoid dirt and grime accumulation between the water stirring component and the bottom of the barrel.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] A washing tub assembly of a washing device, comprising a washing tub and a water stirring member rotatably disposed inside the washing tub, wherein the water stirring member has a certain height along the axial direction of the washing tub and has a maximum radius along the radial direction of the washing tub at a certain distance from the inner surface of the bottom of the washing tub; no impeller is disposed between the bottom of the water stirring member and the bottom of the washing tub;

[0011] The washing tub has a convex washing attachment disposed on the tub peripheral wall, and the washing attachment is at least partially disposed in an area not lower than the maximum radius of the water stirring member.

[0012] Furthermore, the washing tub has a first washing space above the maximum radius of the water stirring member, and a second washing space is formed between the maximum radius of the water stirring member and the inner surface of the tub bottom;

[0013] The washing attachment block is provided at least at a position where the first washing space and the second washing space are connected.

[0014] Further, the washing attachment block includes a first washing attachment block arranged in the first washing space, and a second washing attachment block arranged in the second washing space;

[0015] Alternatively, at least part of the washing blocks has a certain extension length, extending from the first washing space to the second washing space.

[0016] Furthermore, the maximum dimension of the first washing attachment block disposed in the first washing space along the radial direction of the washing tub is greater than or equal to the maximum dimension of the second washing attachment block disposed in the second washing space along the radial direction of the washing tub.

[0017] Furthermore, the upper end of the second washing attachment block is not higher than the height of the maximum radius of the water stirring member, and at least part of the first washing attachment block extends downward into the second washing space;

[0018] Preferably, the upper end of the second washing block is flush or substantially flush with the maximum radius of the water stirring member.

[0019] Furthermore, a maximum dimension D1 of a portion of the washing attachment in the first washing space along the radial direction of the washing tub is greater than a maximum dimension D2 of a portion of the washing attachment in the second washing space along the radial direction of the washing tub.

[0020] Furthermore, the maximum radial dimension D1 of the washing attachment block in the first washing space is formed at a position close to the upper end of the washing attachment block, and the maximum radial dimension D2 of the washing attachment block in the second washing space is formed at a position close to the lower end of the washing attachment block;

[0021] Between the positions where the radial maximum dimension D1 and the radial maximum dimension D2 are formed, the radial dimension of the washing attachment block along the washing tub is first reduced to a radial minimum dimension D0 from top to bottom, and then increases.

[0022] Furthermore, the height at which the radial minimum dimension D0 is located is flush or substantially flush with the height at which the radius of the water-stirring member is at its maximum.

[0023] Furthermore, the top of the water-stirring member is arranged below the barrel opening of the washing barrel, and the washing attachment block is at least partially arranged in an area higher than the top of the water-stirring member.

[0024] A washing device comprises the washing barrel assembly of the washing device described above.

[0025] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0026] In the present invention, the maximum radius of the water stirring member is at a certain distance from the bottom of the washing barrel, and no impeller is arranged between the bottom of the water stirring member and the inner surface of the barrel bottom, thus eliminating the structure of the impeller covering the barrel bottom, and avoiding the problem of dirt and grime accumulating at the barrel bottom. At the same time, a raised washing block is arranged at least in the area of ​​the barrel circumference not lower than the maximum radius of the water stirring member. When washing with a water level higher than the maximum radius, the washing block can strengthen the stirring force of the upper washing water, ensuring that the clothes at this location also have a good washing effect.

[0027] In the present invention, the water stirring member can provide a certain stirring force to the washing water in the second washing space, while in the first washing space, the stirring force of the water stirring member on the washing water due to rotation is very small. The washing blocks in the first washing space are arranged to have a larger size along the radial direction of the washing tub, which is beneficial to control the water flow impact force on the washing blocks in the first washing space and the second washing space to be relatively close, thereby avoiding affecting the stability of the washing tub structure.

[0028] In the present invention, the washing block has a minimum dimension along the radial direction of the washing tub at or near the height where the radius of the water stirring member is the largest, which is conducive to cooperating with the water stirring member to drive the clothes in the first washing space and the second washing space to move in their respective washing spaces for washing, thereby achieving a better washing effect.

[0051] 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 are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] 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.

[0053] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] like Figures 2 to 18 As shown, an embodiment of the present invention provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing device having a clothes washing function.

[0056] 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.

[0057] More specifically, the output shaft of the driving device is respectively connected to the stirring shaft 300 and the dehydrating shaft 110. The stirring shaft 300 is connected to the water stirring member 200 and relatively fixed, and is used to drive the water stirring member 200 to rotate. The dehydrating shaft 110 is fixed to the bottom 100-3 of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0058] During the washing process, the driving device drives the water stirring member 200 to rotate alone, or drives the water stirring member 200 and the washing tub 100 to rotate in opposite directions, so as to utilize the relative rotation trend between the water stirring member 200 and the washing tub 100 to stir the clothes C and the washing water in the tub, thereby achieving a cleaning effect on 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 a high speed, and utilizes centrifugal force to spin dry the clothes C in the tub.

[0059] However, when the lint and dirt shed from the clothes C during the washing process are mixed into the washing water, if there is a relatively narrow gap structure between the water stirring member 200 and the washing tub 100, these lint and dirt are easily hidden in the gap structure and are difficult to be taken out by the impact force of the water flow during the washing process, and the user needs to manually disassemble the water stirring member 200 for cleaning. If the user does not clean it for a long time, a large amount of dirt will accumulate in the gap between the water stirring member 200 and the washing tub 100, which is easy to breed bacteria, causing the problem of secondary contamination of the clothes C.

[0060] On the other hand, since the water stirring member 200 is installed close to the bottom 100-3 of the washing tub 100, when washing at a relatively low water level, the washing water can be effectively stirred by rotating the water stirring member 200 relative to the washing tub 100. However, if washing is performed at a higher water level, especially when the water level exceeds a certain height of the water stirring member 200, the washing water in the upper part cannot receive sufficient stirring force, and thus the clothes in this space may not be fully washed.

[0061] Embodiment 1

[0062] like Figure 2 As shown, this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly. On the one hand, it solves the problem that there are dead corners between the water stirring member 200 and the washing tub 100 that are difficult to clean and can hide dirt and grime. On the other hand, it can improve the cleaning effect of clothes in the upper space during high water level washing.

[0063] Specifically, the washing tub assembly described in this embodiment includes a washing tub 100, and a water stirring member 200 rotatably disposed inside the washing tub 100. The water stirring member 200 extends upward from the bottom area of ​​the washing tub 100, has a certain height along the axial direction of the washing tub 100, and has a maximum radius along the radial direction of the washing tub 100 at a certain distance from the inner surface of the tub bottom 100-3, forming the maximum radius Rmax of the water stirring member 200. No impeller is disposed between the bottom of the water stirring member 200 and the tub bottom 100-3 of the washing tub 100, or a similar structure with a larger size in the radial direction is provided.

[0064] Further, the water stirring member 200 includes a mounting portion 210-1 having a certain length 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, and 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.

[0065] In the above scheme, the assembly part 210-1 is arranged at the bottom of the water stirring member 200 for connecting with the stirring shaft 300. During washing, the water stirring member 200 rotates relative to the washing tub 100, and the water stirring part 240 is used to stir the washing water and clothes in the tub.

[0066] In this embodiment, no impeller is provided between the bottom of the water stirring member 200 and the barrel bottom 100-3 of the washing barrel 100, which means that the lower end surface of the assembly portion 210-1 is directly opposite to the inner surface of the barrel bottom 100-3, and there is no shielding structure between the two.

[0067] As a specific embodiment, the lower end surface of the assembly part 210-1 is flush with or slightly higher than the inner surface of the barrel bottom 100-3, the side wall of the assembly part 210-1 is directly opposite to the inner surface of the side wall of the washing barrel 100, and the distance from the side wall of the assembly part 210-1 to the outer periphery of the barrel bottom 100-3 is basically the same as the distance from the side wall of the stirring shaft 300 to the outer periphery of the barrel bottom 100-3.

[0068] More specifically, the assembly part 210-1 is mounted on the upper end of the stirring shaft 300, and the distance from the side wall of the assembly part 210-1 to the outer periphery of the barrel bottom 100-3 is slightly larger than the distance from the side wall of the stirring shaft 300 to the outer periphery of the barrel bottom 100-3, and the difference between the two is only the wall thickness of the assembly part 210-1.

[0069] As another specific 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 in the area near the mounting portion 210-1. In other words, within a certain height range from the lower end of the water stirring member 200 upward, the mounting portion 210-1 is the smallest radius section within the range, and the disc-shaped water stirring portion without a bottom of the water stirring member 200 will not cover the tub bottom 100-3.

[0070] As another specific embodiment, in the area between the upper end of the assembly portion 210 - 1 and the maximum radius Rmax, the vertical downward projection of the outer periphery of any horizontal cross section of the water stirring portion 240 is directly located on the inner surface of the barrel bottom 100 - 3 .

[0071] In the above scheme, by removing the impeller arranged at the bottom of the washing tub 100, it is beneficial to expose most of the area of ​​the tub bottom 100-3 in the washing space. It should be noted that the washing space refers to the space area that the clothes can reach during the washing process. Therefore, by adopting the above structure, most of the area of ​​the tub bottom 100-3 can be in contact with the clothes during the washing process to prevent dirt from adhering, avoiding the problem that dirt is easily hidden between the stirring device and the tub bottom of the existing washing equipment and is difficult to clean.

[0072] Thus, compared with a conventional pulsator washing machine or an agitator washing machine with a radial agitator, the water stirring member 200 of this embodiment is installed in the washing tub 100, so that the bottom 100-3 of the tub can be almost completely exposed in the washing space, and the contact and friction between the clothes and the bottom 100-3 of the tub can be used to prevent the adhesion of dirt. In this way, the effect of preventing dirt accumulation is better, and the secondary contamination of the clothes by the dirt accumulation can be avoided, thereby improving the user experience.

[0073] On the other hand, in a conventional pulsator washing machine, when washing, the clothes are covered with a large area on the upper surface of the pulsator and contact with it, and the relative rotation of the pulsator and the barrel body generates a large force on the clothes, which easily causes the clothes to be entangled. Compared with the pulsator washing machine, when the water stirring member 200 in this embodiment is washed at a water level lower than the height of the maximum radius Rmax, the clothes will only contact the side of the water stirring member 200, and the clothes are mainly driven to move in the barrel by the water flow impact generated by the water stirring member 200 stirring the washing water, and the force directly applied by the water stirring member 200 to the clothes is greatly reduced, which also plays a role in preventing the clothes from being entangled. If the water level is higher than the height of the maximum radius Rmax, although some clothes will be washed above the maximum radius Rmax, since the maximum radius of the water stirring member 200 in this embodiment is much smaller than the radius of the washing barrel 100, instead of being closer to the barrel diameter like the pulsator diameter in the pulsator washing machine, the contact area between the water stirring member 200 and the clothes in this embodiment is much smaller than the contact area between the pulsator and the clothes in the pulsator washing machine, and the possibility of clothes being entangled is greatly reduced.

[0074] Furthermore, since the contact area between the clothes and the water stirring member 200 is reduced, the friction between the clothes and the water stirring member 200 is reduced, which helps to reduce the wear of the water stirring member 200 on the clothes and can also reduce the motor energy consumption when the driving device drives the water stirring member 200 to rotate.

[0075] It should be noted that, in the embodiment of the present invention, the radius of the water stirring member 200 refers to the cross section of the water stirring member taken along the horizontal direction (see Figure 3 ), the distance from the farthest point on the horizontal section to the center of rotation.

[0076] Specifically, if the horizontal cross section of the water stirring member 200 is Figure 4 If the horizontal cross section of the water stirring member 200 is Figures 5 to 10 For the non-circular shape shown, 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 figure).

[0077] Accordingly, in this embodiment and subsequent embodiments, the “diameter” mentioned refers to twice the radius mentioned above.

[0078] In a further solution of this embodiment, a raised washing block 600 is provided on the barrel peripheral wall 100 - 4 of the washing barrel 100 , and the washing block 600 is at least partially provided in an area not lower than the maximum radius Rmax of the water stirring member 200 .

[0079] The washing attachment block 600 can be an independent part separated from the washing tub 100 and fixed to the tub peripheral wall 100-4 by screws or similar connecting parts. The washing attachment block 600 can also be connected or formed integrally with the tub peripheral wall 100-4 of the washing tub 100. When the tub peripheral wall 100-4 of the washing tub 100 is made of metal, the washing attachment block 600 can also be a press-type structure on the tub peripheral wall 100-4.

[0080] The washing device has the above structure. When washing at a water level lower than the maximum radius Rmax, the water stirring member 200 rotates relative to the washing tub 100 to stir the washing water, thereby driving the clothes to move below the maximum radius Rmax of the water stirring member 200 for washing. When washing at a water level higher than the maximum radius Rmax, the stirring force of the water stirring member 200 on the upper washing water is insufficient, but the washing attachment block 600 protruding from the tub peripheral wall 100-4 can strengthen the stirring force of the upper washing water, thereby ensuring that the clothes located above the maximum radius Rmax can also have a good washing effect.

[0081] It is understandable that when washing with a water level higher than the maximum radius Rmax, the preferred washing method is to simultaneously drive the washing tub 100 and the water stirring member 200 to rotate, so that the stirring effect of the upper washing water is more obvious.

[0082] In a preferred embodiment, the top of the water stirring member 200 is arranged below the barrel opening of the washing tub 100, and the washing attachment block 600 is at least partially arranged in an area higher than the top of the water stirring member 200. In this way, the washing attachment block 600 can be used to strengthen the impact of the washing water flow in the space above the water stirring member 200 to ensure the washing effect.

[0083] Furthermore, the washing tub 100 has a first washing space above the maximum radius Rmax of the water stirring member 200, and a second washing space is formed between the maximum radius Rmax of the water stirring member 200 and the inner surface of the tub bottom 100-3. Specifically, the second washing space is composed of the side of the water stirring member 200, the tub peripheral wall 100-4 and the inner surface of the tub bottom 100-3. When washing in the second washing space, the clothes can fully contact the above surfaces, thereby preventing the problem of dirt and grime between the water stirring member 200 and the inner wall of the washing tub 100 to the greatest extent.

[0084] As a specific embodiment, at least at the position where the first washing space and the second washing space meet, a washing block 600 is provided. More specifically, the washing block 600 has a certain extension length in the axial direction, and its lower end at least extends to the height where the maximum radius Rmax is located.

[0085] With the above structure, during washing, the washing water in the first washing space is stirred by the washing attachment 600, thereby driving the clothes to move in the first washing space. In the second washing space, the relative rotation of the water stirring member 200 and the washing tub 100 can drive the clothes to rise to the maximum radius Rmax, and then move toward the periphery. After the clothes contact the washing attachment 600, they are blocked and then fall back to the bottom of the washing tub 100 along the tub peripheral wall 100-4.

[0086] In a further solution of this embodiment, the bottom 100-3 of the washing tub 100 has a mounting portion 100-2 located at the center, the assembly portion 210-1 is arranged above the mounting portion 100-2 of the bottom 100-3, and the stirring shaft 300 rotatably passes through the mounting portion 200-1 and is connected to the assembly portion 210-1. The area of ​​the bottom 100-3 extending outward from the mounting portion 100-2 to the barrel wall 100-4 of the washing tub 100 is a washing surface 100-31 that can contact clothes during washing.

[0087] As a specific embodiment, the mounting portion 100-2 is a mounting through hole opened at the center of the barrel bottom 100-3, and the mounting through hole passes through the upper and lower sides of the barrel bottom 100-3. The stirring shaft 300 is rotatably inserted into the mounting through hole, and the diameter of the lower end of the assembly portion 210-1 is equal to or substantially equal to the diameter of the mounting through hole.

[0088] With the above structure, the projection area formed by the lower end of the assembly portion 210-1 projecting onto the barrel bottom 100-3 of the washing barrel 100 substantially coincides with the installation through hole. The barrel bottom 100-3 located outside the installation through hole is the washing surface 100-31, so that the washing surface 100-31 is completely exposed to the washing space, thereby preventing the problem of dirt accumulation on the inner surface of the barrel bottom 100-3 of the washing barrel 100 to the greatest extent.

[0089] As a specific implementation, the washing surface 100 - 31 occupies 90% or more of the total area of ​​the barrel bottom 100 - 3 of the washing barrel 100 , and preferably 95% or more of the total area of ​​the barrel bottom 100 - 3 of the washing barrel 100 .

[0090] As a detailed structure, the assembly part 210-1 is mounted on the upper end of the stirring shaft 300, and the diameter of the lower end of the assembly part 210-1 is greater than or equal to the diameter of the stirring shaft 300. The aperture of the mounting through hole is adapted to the diameter of the stirring shaft 300. Specifically, the aperture of the mounting through hole is slightly larger than the diameter of the stirring shaft 300, and the side wall of the stirring shaft 300 does not contact the outer periphery of the mounting through hole, ensuring that the rotation of the stirring shaft 300 is not affected.

[0091] In a specific embodiment, the diameter of the lower end of the assembly part 210-1 is equal to the diameter of the installation through hole, so that the projection of the lower end of the assembly part 210-1 to the barrel bottom 100-3 completely overlaps with the installation through hole. At this time, the lower end of the assembly part 210-1 can be set to be flush with the inner surface of the barrel bottom 100-3, and the washing surface 100-31 around the installation through hole can also be completely exposed to the washing space.

[0092] In another specific embodiment, the diameter of the lower end of the assembly part 210-1 is slightly larger than the diameter of the installation through hole. At this time, the projection of the lower end of the assembly part 210-1 to the barrel bottom 100-3 slightly exceeds the area of ​​the installation through hole. In order to avoid the problem of dirt and grime being hidden in the area of ​​the washing surface 100-31 covered by the projection area of ​​the lower end of the assembly part 210-1, the lower end surface of the assembly part 210-1 is spaced from the inner surface of the barrel bottom 100-3, so that the clothes can contact the lower end surface of the assembly part 210-1 and the area of ​​the washing surface 100-31 close to the installation part 100-2.

[0093] In another specific embodiment, the diameter of the lower end of the assembly part 210-1 is slightly smaller than the diameter of the installation through hole. In this case, the projection of the lower end of the assembly part 210-1 to the barrel bottom 100-3 is within the range of the installation through hole. Similar to the first specific embodiment, the lower end of the assembly part 210-1 can also be set to be flush with the inner surface of the barrel bottom 100-3. Since the projection area of ​​the lower end of the assembly part 210-1 does not overlap with the washing surface 100-31, it can be ensured that the washing surface 100-31 is completely exposed in the washing space.

[0094] In a further solution of this embodiment, the water stirring portion 240 includes a support column 210 extending axially from the upper end of the assembly portion 210-1, and a water stirring structure disposed on the side wall of the support column 210. Since a second washing space is formed in the washing tub 100 in a region lower than the maximum radius Rmax, the water stirring structure is at least disposed in a region lower than the maximum radius Rmax.

[0095] As a specific embodiment, the water stirring structure includes a water stirring rib 220 protruding from the side wall of the support column 210 and extending in the axial direction. The protruding 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 water stirring rib 220 has a surface arranged opposite to the rotation direction, which can achieve an effective stirring effect.

[0096] More specifically, a plurality of water-stirring ribs 220 are arranged at intervals along the circumferential direction on the side wall of the support column 210, and the plurality of water-stirring ribs 220 are preferably arranged symmetrically with respect to the rotation axis. The clothes C can be washed in the interval area between two adjacent water-stirring ribs 220, thereby contacting the two side surfaces of the water-stirring ribs 220 and the area of ​​the side wall of the support column 210 between the two water-stirring ribs 220, thereby avoiding the existence of a cleaning dead corner on the side wall of the support column 210 where dirt is easily attached.

[0097] The water-stirring member 200 having the above structure has a side surface below the maximum radius Rmax, which includes 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 point on the water-stirring rib 220 from the rotation axis and the rotation axis.

[0098] In the above structure, the radius of any horizontal section of the water stirring portion 240 specifically refers to the distance from the farthest end of the water stirring rib 220 from the axis to the central axis on the horizontal section. When the number of the water stirring ribs 220 is an even number, the length of the line connecting the farthest ends of two relative water stirring ribs 220 from the axis is the diameter of the horizontal section of the water stirring portion 240. When the number of the water stirring ribs 220 is an odd number, there are no relatively arranged water stirring ribs 220, and at this time the horizontal section of the water stirring portion 240 does not form an axisymmetric figure, but the diameter of the horizontal section of the water stirring portion 240 is still twice the radius determined above.

[0099] In another specific embodiment, the water stirring ribs extend spirally along the side wall surrounding the support column. In this case, the horizontal cross section of the water stirring portion may not form a regular geometric shape, but the radius of the horizontal cross section of the water stirring portion is still the distance from the farthest end of the water stirring ribs from the axis to the central axis on the cross section.

[0100] In a specific structure of this embodiment, the maximum radius Rmax is formed at a position close to the top of the water stirring portion 240, but at a certain distance from the top of the water stirring member 200. Specifically, the upper side surface of the water stirring portion 240 at the maximum radius Rmax is an upwardly convex curved surface, and the highest point of the curved surface forms the top of the water stirring member 200.

[0101] As a detailed solution, a water stirring plate 230 perpendicular to the axial direction is provided at the upper end of the support column 210 , the upper surface of the water stirring plate 230 is an upwardly convex curved surface, and the outer periphery of the water stirring plate 230 forms the maximum radius Rmax of the water stirring portion 240 .

[0102] In the preferred structure, the upper end of the water-stirring rib 220 extends upward to the lower surface of the water-stirring pan 230, thereby preventing a dead corner between the water-stirring rib 220 and the water-stirring pan 230 that cannot contact clothes and is prone to dirt and grime.

[0103] 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. Similarly, 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.

[0104] As a specific solution, the side wall of the support column 210 extends in the vertical direction or close to the vertical direction, and the radial dimension of the water-stirring rib 220 along the washing tub 100 increases with the increase of 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 dimension of the water-stirring rib 220 along the washing tub 100 is maximized as much as possible, which can enhance the agitation of the washing water and enhance the washing effect.

[0105] In this embodiment, the lower end of the water stirring rib 220 can extend to the position where the water stirring portion 240 is connected to the assembly portion 210-1, or can extend to the side wall of the assembly portion 210-1. However, it is understandable that the lower end of the water stirring rib 220 extends to be flush with the lower end surface of the assembly portion 210-1.

[0106] In a preferred embodiment, there is a gap between the lower end of the water-stirring rib 220 and the inner surface of the barrel bottom 100 - 3 to prevent a narrow gap from forming between the lower end of the water-stirring rib 220 and the barrel bottom 100 - 3 that could easily harbor dirt.

[0107] In another preferred embodiment, when the lower end of the water stirring rib 220 is flush with the lower end surface of the assembly portion 210-1, the radial dimension of the water stirring rib 220 at the lower end is close to zero, and the peripheral edge of the water stirring rib 220 on the side away from the axis is extended upward from the outer periphery of the lower end surface of the assembly portion 210-1 toward the outer periphery. In this way, a certain angle is formed between the peripheral edge of the water stirring rib 220 and the inner surface of the barrel bottom 100-3, thereby ensuring that the area near the center of the barrel bottom 100-3 is exposed to the second washing space, and will not be blocked by the water stirring rib 220 and have a dead corner where dirt and grime are hidden.

[0108] In a more optimal solution, at the lower end of the water-stirring rib 220, the acute angle between its outer edge and the horizontal direction is greater than 20°, and more preferably greater than 30°, to ensure that the area near the center of the barrel bottom 100-3 can contact the clothes.

[0109] With the water stirring member 200 having the above structure, during washing, in the second washing space, the water stirring ribs 220 rotate with the water stirring member 220 to stir the washing water and clothes in the second washing space. In the first washing space, the washing water is mainly stirred by the washing attachment 600 and moves with the water flow, and the washing effect can be further enhanced by friction with the upper curved surface of the water stirring plate 230.

[0110] However, it is understandable that the diameter of the water stirring pan 230 in this embodiment is significantly smaller than the barrel diameter of the washing tub 100, rather than being closer to the barrel diameter than the radial dimension of the impeller in the impeller washing machine. Therefore, although the clothes in the first washing space will contact the upper surface of the water stirring pan 230, the resistance to the rotation of the water stirring member 200 is relatively small, which does not affect the effect of the water stirring member 200 in this embodiment in reducing the energy consumption of the driving device motor. In addition, since part of the clothes are washed in the second washing space below the water stirring pan 230, that is, the relative reduction in the first washing space will not be too much, it is also beneficial to reduce the resistance to the rotation of the water stirring member 200, thereby reducing the energy consumption of the driving device motor.

[0111] In a further solution of this embodiment, the side of the water stirring rib 220 away from the axis is a curved surface extending in a curved manner, which can drive the washing water in the second washing space to have a tendency to flow along the curved surface during washing.

[0112] As a specific implementation, the peripheral edge of the water stirring rib 220 on the side away from the axis extends upward at a certain angle to the horizontal direction, and in the lower area, the acute angle between it and the horizontal direction increases with the increase of height, forming a curved surface that bends away from the axis. After extending beyond a certain height, the acute angle between it and the horizontal direction decreases with the increase of height, forming a curved surface that bends toward the axis, and finally extends to the periphery of the water stirring plate 230.

[0113] In the above scheme, the outer edge of the water stirring rib 220 is a curved surface extending upward. During the washing process, in the second washing space, the rotation of the water stirring member 200 can drive the washing water to produce a flow trend that conforms to the curved surface, thereby lifting the clothes upward near the center area of ​​the barrel bottom 100-3, and guiding the clothes to move toward the periphery after the clothes rise with the water flow to a point close to the maximum radius Rmax. In this way, the turning movement of the clothes in the barrel is strengthened, the washing effect can be enhanced, and at the same time, the clothes can be prevented from excessively gathering toward the center and causing entanglement.

[0114] In this embodiment, the water stirring member 200 is generally in an inverted cone shape. During washing, the relative rotation of the water stirring member 200 and the washing tub 100 can drive the clothes in the second washing space to move and be washed.

[0115] In a specific embodiment, the clothes move along a circular path in the second washing space. The circular path 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 below the position close to the maximum radius Rmax, then move toward the periphery, and then fall back to the bottom of the washing tub 100.

[0116] In a further embodiment, the washing attachment 600 disposed on the barrel peripheral wall 100 - 4 at least partially extends from the first washing space to the second washing space.

[0117] In a specific structure, the washing attachment block 600 extends in a direction parallel to the axis, and the upper end of the washing attachment block 600 is higher than the height of the maximum radius Rmax, preferably higher than the top height of the water stirring member 200. The lower end of the washing attachment block 600 is set lower than the height of the maximum radius Rmax. In other words, the same washing attachment block 600 is located in the first washing space and the second washing space at the same time.

[0118] In a more detailed structure, a plurality of washing attachment blocks 600 of the same structure are arranged on the barrel peripheral wall 100-4, and the plurality of washing attachment blocks 600 are spaced apart along the circumference of the washing barrel 100. Preferably, the spacing angles between any two adjacent washing attachment blocks 600 are consistent.

[0119] When the washing device having the above structure washes, in the first washing space, the upper part of the washing attachment 600 stirs the washing water, thereby generating a water flow close to the circumferential flow along the washing tub 100, thereby driving the clothes to move alternately forward and reverse along the circumference in the first washing space for washing.

[0120] In the second washing space, the clothes move along a circular path, specifically: the clothes move toward the central area along the washing surface 100-31 of the barrel bottom 100-3, and move upward along the side wall of the support column 210 with the central area. When rising to a point close to the maximum radius Rmax, the clothes move toward the periphery, and after contacting the barrel washing block 600, they move downward along the surface of the washing block 600. After falling below the lower end of the washing block 600, they continue to fall along the inner surface of the barrel wall 100-4, and finally return to the bottom of the washing barrel 100.

[0121] It should be noted that after the clothes move outward at the maximum radius Rmax, they may also directly contact the area of ​​the barrel peripheral wall 100-4 between two adjacent washing attachment blocks 600. In the above case, the clothes directly fall along the inner surface of the barrel peripheral wall 100-4 to the bottom of the washing barrel 100.

[0122] In addition, the clothes moving to the central area along the washing surface 100-3 can also be lifted to the maximum radius Rmax along the outer edge of the water-stirring ribs 220, and then move toward the periphery under the action of inertia and centrifugal force until they contact the washing attachment 600 or the barrel wall 100-4, and then move downward back to the bottom of the washing barrel 100.

[0123] In the above scheme, the clothes may first move downward along the surface of the washing attachment 600, and then continue along the barrel wall 100-4 and finally return to the barrel bottom 100-3. Especially at the lower end of the washing attachment 600, the movement direction of the clothes will turn to the barrel wall 100-4, which is equivalent to extending the movement path of the clothes during the falling process. Compared with the method of falling directly along the barrel wall 100-4, the surface contacted by the clothes during the falling process is increased, thereby increasing the friction on the clothes and improving the washing effect.

[0124] In a further solution of this embodiment, the washing attachment 600 has a maximum dimension D1 in the radial direction of the washing tub 100 in the first washing space, and has a maximum dimension D2 in the radial direction of the washing tub 100 in the second washing space. The maximum dimension D1 is greater than the maximum dimension D2.

[0125] During washing, as the washing tub 100 rotates, the surface of the washing attachment 600 perpendicular to the rotation direction pushes the washing water, thereby stirring the washing water to drive the clothes to move. Under the condition of a certain water flow intensity, the larger the surface area perpendicular to the rotation direction, the greater the reaction force of the washing water on the washing attachment 600.

[0126] It is understandable that the radial dimension of the washing attachment block 600 mentioned above along the washing tub 100 is the height of the protrusion of the washing attachment block 600 relative to the inner surface of the tub peripheral wall 100-4. The larger the radial dimension of the washing attachment block 600 along the washing tub 100, the larger the surface area perpendicular to the rotation direction within the same height range, and the greater the reaction force of the washing water under the same water flow intensity.

[0127] In the solution of this embodiment, the stirring effect of the water stirring member 200 on the washing water in the first washing space is weak and even negligible, while in the second washing space, the water stirring member 200 plays a major role in stirring the washing water, thereby providing a higher water flow intensity. By setting the portion of the washing attachment 600 in the first washing space to have a larger protrusion height, it is helpful to control the water flow impact force on the upper and lower parts of the washing attachment 600 to be closer, avoiding a large difference in the force of the water flow on the washing attachment 600 between the upper and lower parts, thereby causing a significant torque between the upper and lower parts of the washing tub 100, affecting the stability of the structure of the washing tub 100.

[0128] In a detailed structure, the distance from the upper end of the washing attachment 600 to the height of the maximum radius Rmax of the water stirring member 200 is greater than the distance from the lower end of the washing attachment 600 to the height of the maximum radius Rmax of the water stirring member 200. In other words, the extension length of the washing attachment 600 in the first washing space is greater than its extension length in the second washing space. The maximum radial dimension D1 of the washing attachment is greater than the maximum radial dimension D2, which further ensures that the washing attachment 600 has a larger surface area perpendicular to the rotation direction in the first washing space.

[0129] In a further embodiment, the maximum radial dimension D1 of the washing attachment block 600 in the first washing space is formed at a position close to the upper end of the washing attachment block 600, and the maximum radial dimension D2 of the washing attachment block 600 in the second washing space is formed at a position close to the lower end of the washing attachment block 600. Between the positions where the maximum radial dimensions D1 and D2 are formed, the radial dimension of the washing attachment block 600 along the washing tub 100 is first reduced to a minimum radial dimension D0 from top to bottom, and then increases.

[0130] As a specific solution, the surface of the washing block 600 facing the axis of the washing tub 100 extends downwardly from the position where the maximum radial dimension D1 is formed, gradually approaching the tub peripheral wall 100-4, until it extends to a position that is flush or substantially flush with the height of the maximum radius Rmax of the water stirring member 200. Afterwards, the surface of the washing block 600 continues to extend downwardly in a direction gradually away from the tub peripheral wall 100-4, and finally forms the maximum radial dimension D2. Thus, at a position substantially consistent with the height of the maximum radius Rmax of the water stirring member 200, the surface of the washing block 600 facing the axis of the washing tub 100 forms an inner concave portion 603.

[0131] In the above solution, the height at which the minimum radial dimension D0 of the washing attachment 600 is located is flush with the height at which the maximum radius Rmax of the water stirring member 200 is located, or it may be slightly higher or lower than the height at which the maximum radius Rmax is located.

[0132] By adopting the above-mentioned structure of the washing attachment block 600 and the relative position relationship between the washing attachment block 600 and the water stirring member 200, during washing, in the second washing space, the clothes moving toward the periphery below the maximum radius Rmax can just contact the inner recess 603 of the washing attachment block 600. Above the inner recess 603, the surface of the washing attachment block 600 extends obliquely toward the direction close to the central axis, which has a certain blocking effect on the clothes, so that the clothes can be better guided to move downward along the surface of the washing attachment block 600.

[0133] In the first washing space, when the clothes move with the water flow and contact the inner concave portion 603 of the washing attachment 600, they can be lifted along the surface of the washing attachment 600. In this way, during washing, the clothes in the first washing space and the second washing space are washed relatively independently, and the clothes rarely move between the first washing space and the second washing space, which can prevent the problem of clothes moving irregularly and easily getting tangled.

[0134] In a more detailed structure, the upper end surface of the washing attachment block 600 is substantially parallel to the horizontal plane, and a first transition fillet 601 is provided between the upper end surface and the surface of the washing attachment block 600 facing the axis of the washing tub 100, and the radial maximum dimension D1 of the washing attachment block 600 is formed at the lowest point of the first transition fillet 604.

[0135] There is almost no lower end surface parallel to the horizontal plane at the lower end of the washing attachment block 600, but it starts to extend in a horizontal or nearly horizontal direction from the inner surface of the barrel peripheral wall 100-4, and the extension direction is bent upward along an arc to form a second transition fillet 602, and finally connected to the surface of the washing attachment block 600 facing the axis of the washing barrel 100. The arc angle corresponding to the second transition fillet 602 is greater than 90°, and the radial maximum dimension D2 of the washing attachment block 600 is formed at a position slightly above the middle of the second transition fillet 602.

[0136] The washing attachment block 600 has the above structure, which can reduce the scratches on the clothes during washing, thereby preventing the clothes from being damaged by friction with the washing attachment block 600.

[0137] In this embodiment, the water stirring member 200 forms a first washing space and a second washing space in the washing tub 100. The inner surface of the bottom 100-3 of the washing tub 100 is directly exposed to the second washing space and can contact the clothes during washing, effectively avoiding the problem of dirt and grime between the water stirring member 200 and the bottom 100-3. By arranging a raised washing attachment 600 on the tub peripheral wall 100-4 and cooperating with the specific structure of the washing attachment 600, on the one hand, the water flow intensity in the first washing space is enhanced to ensure the washing effect, and on the other hand, it can also cooperate with the water stirring member 200 to better guide the clothes to move in the first washing space or the second washing space, further ensuring the washing effect.

[0138] Embodiment 2

[0139] like Fig.11 and Fig.12 As shown, this embodiment provides a specific structure of a water stirring member 200 based on the above-mentioned embodiment 1.

[0140] Specifically, in this embodiment, the water stirring portion 240 of the water stirring member 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.

[0141] As a specific embodiment, the top surface of the water stirring plate 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.

[0142] As a specific embodiment, the assembly portion 210-1 is provided with a spline groove 210-6 extending coaxially upward from the bottom end face of the assembly portion 210-1, and the spline groove 210-6 is at least partially sleeved on the end of the stirring shaft (not shown in the figure) and is key-connected to the stirring shaft.

[0143] In one detailed structure, the assembly part 210-1 and the support column 210 are an integrally formed structure, and the spline groove 210-6 is directly formed inside the assembly part 210-1. In another detailed structure, the assembly part 210-1 includes a main body integrally formed with the support column 210, and a spline shaft arranged at the lower end of the main body, and the spline groove 210-6 is arranged on the spline shaft.

[0144] In a specific structure of this embodiment, the maximum radius Rmax of the water stirring part 240 is formed by the outer periphery of the water stirring plate 230. Below the water stirring plate 230, the radial dimension of the support column 210 increases with the increase of height, thereby forming a guiding surface for guiding the movement of clothes during washing.

[0145] Specifically, the support column 210 extends from bottom to top and includes a first extension section 211 and a second extension section 212 connected in sequence. The side wall of the first extension section 211 extends upward from the upper end of the assembly portion 210-1. The side wall of the second extension section 212 extends from the upper end of the first extension section 211 to the periphery and tilts upward, and finally extends to the height where the radius Rmax of the water stirring portion 240 is the maximum, that is, extends to the lower surface of the water stirring plate 230.

[0146] It should be noted that the side wall of the first extension section 211 extends upward from the upper end of the assembly portion 210-1, and can be either vertically extended upward or inclined upward relative to the vertical direction, gradually approaching or moving away from the barrel wall 100-4 of the washing barrel 100, or can be extended upward along a curve with a larger curvature and gradually approaching or moving away from the barrel wall 100-4 of the washing barrel 100.

[0147] More specifically, the side wall of the first extension section 211 extends in a straight line and is inclined outward at a small angle relative to the vertical direction. The side wall of the second extension section 212 is inclined at a larger angle to the vertical direction than the side wall of the first extension section 211, and as the height increases, the inclination angle between the side wall of the second extension section 212 and the vertical direction gradually increases, forming a curved surface that bends toward the axis.

[0148] In a detailed solution, the upper end of the side wall of the second extension section 212 overlaps 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 .

[0149] 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 central area of ​​the washing tub 100 to the bottom of the central 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 to rise from the second guide surface 214 to the first guide surface 213 during washing.

[0150] Specifically, the water stirring member 200 provided in this embodiment is applied to a washing device. During washing, the water stirring member 200 rotates relative to the washing tub 100, and the clothes can move along the bottom 100-3 of the washing tub 100 toward the central area, and then move upward along the second guide surface 214 to the first guide surface 213, and then move toward the periphery under the guidance of the first guide surface 213, and then fall in the area close to the barrel wall 100-4 of the washing tub 100, forming a circular path. On the one hand, the tumbling of the clothes in the tub can be enhanced to improve the washing effect, and on the other hand, the probability of the clothes concentrating toward the center and getting entangled is reduced.

[0151] 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 both and the vertical direction is the same. That is, 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.

[0152] As another specific embodiment, the inclination angle of the side wall of the second extension section 212 relative to the vertical direction at the lower end position is slightly higher than the inclination angle of the side wall of the first extension section 211 relative to the vertical direction, so that an angle less than but close to 180° is formed at the connection between the first guide surface 213 and the second guide surface 214. In this way, when the clothes move upward along the second guide surface 214 to the first guide surface 213, it can play a certain buffering role on the clothes, and strengthen the tendency of the clothes to move toward the periphery in a rolling manner.

[0153] In a further solution of this embodiment, the lower end of the washing attachment block 600 is flush or substantially flush with the height of the connecting position of the first extension section 211 and the second extension section 212. In other words, the lower end of the washing attachment block 600 can be just flush with the height of the connecting position of the first extension section 211 and the second extension section 212, or can be slightly higher or slightly lower than the height.

[0154] During the movement of the clothes along the aforementioned circular path, the clothes moving along the guide surface formed by the support column 210 change their movement direction at the connecting position of the first extension section 211 and the second extension section 212, from moving upward in a nearly vertical direction to moving obliquely upward toward the periphery. The clothes moving downward in the area close to the barrel peripheral wall 100-4 of the washing barrel 100 move along the first washing attachment block 600, and when they move to the lower end of the washing attachment block 600, they further approach the barrel peripheral wall 100-4, and then fall back to the barrel bottom 100-3 along the barrel peripheral wall 100-4.

[0155] The height at which the lower end of the washing block 600 is located is the same as or close to the height at which the first extension section 211 and the second extension section 212 are connected, which can avoid interference between clothes moving toward the periphery from the central area and clothes moving downward along the washing block 600, thereby ensuring that the clothes are washed along a stable circular path.

[0156] In a further solution of this embodiment, the water stirring rib 220 has a certain extension length along the axial direction of the washing tub 100, extending from the side wall of the first extension section 211 to the side wall of the second extension section 212. A plurality of water stirring ribs 220 are arranged at intervals along the circumference of the support column 210, and the interval angle between two adjacent water stirring ribs 220 enables the clothes to be washed in the interval area between the two adjacent water stirring ribs 220, and the clothes can contact the side wall of the first extension section 211, so as to move upward along the side wall of the first extension section 211, that is, the second guide surface 214.

[0157] In this way, the area between two adjacent water-stirring ribs 220 of the side walls of the first extension section 211 and the second extension section 212 can contact the clothes without generating dead corners where dirt is easily accumulated.

[0158] Furthermore, in the present embodiment, the radial dimension of the water stirring rib 220 along the washing tub 100 increases first and then decreases from the lower end to the upper end.

[0159] As a specific embodiment, the cross-sectional shape of the water stirring rib 220 parallel to the radial direction of the washing tub 100 is close to a shuttle shape, and the peripheral edge surface of the water stirring rib 220 extends from bottom to top, and the acute angle between the extension direction and the vertical direction gradually decreases, so that the peripheral edge surface of the water stirring member 200 forms a curved surface that bends toward the barrel wall of the washing tub 100. The upper end of the peripheral edge surface of the water stirring rib 220 coincides with the outer periphery of the water stirring tray 230.

[0160] The water-stirring ribs 220 have the above-mentioned structure, which can form a Coanda effect during washing, driving the water flow to flow along the outer peripheral edge of the water-stirring ribs 220, so that in the area close to the axis of the washing tub 100, the water flow has a flow tendency to fit the outer peripheral edge of the water-stirring ribs 220, and as the height increases, the flow direction of the water flow is closer to upward rather than flowing toward the periphery. In this way, the lifting force of the water flow on the clothes in the area close to the axis can be enhanced, driving the clothes to move upward to the first guide surface 213, and finally forming a circular path.

[0161] 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 ribs 220 after contacting the water-stirring ribs 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 to the bottom 100-3 of the barrel along the wall of the washing barrel 100.

[0162] In the preferred scheme of this embodiment, a smoothly transitioned rounded corner 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 of the inside of the washing barrel 100 to the greatest extent.

[0163] 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 corners that may scratch and damage clothes.

[0164] In this embodiment, by designing the specific structure of the water stirring member 200, a space for washing clothes is formed below the maximum radius Rmax of the water stirring portion 240. Washing clothes in this space effectively avoids the problem that the water stirring member 200 is easy to hide dirt and grime between the barrel bottom 100-3 and is difficult to clean. At the same time, the specific structure of the support column 210 and the water stirring rib 220 is coordinated, and the relative position relationship between the washing attachment 600 and the guide surface on the support column 210 is combined, so that the effect of driving the clothes to move along the circular path below the maximum radius Rmax is better.

In order to prevent water from entering the cavity 210-9, a blocking component is installed at the opening.

[0178] Preferably, a sealing groove 210-4 is provided on the top of the water stirring member 200, and the sealing groove 210-4 is formed by being coaxially recessed downward from the top surface of the water stirring plate 230.

The operator disassembles and assembles the screw 210-7 through the opening on the bottom of the sealing groove 210-4 and the cavity 210-9 of the hollow column 210-8. The screw is preferably a countersunk screw.

[0180] 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 .

[0181] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion.

[0182] The top of the flat plate portion and the top of the water stirring member 200 are in the same plane.

[0183] The sealing groove 210-4 includes a first section and a second section with increasing diameters from top to bottom. The lower end of the plug-in portion is provided with a limiting protrusion protruding from the outer wall of the lower end of the plug-in portion in a direction away from the axis of the water-stirring member 200, and the limiting protrusion is engaged at the junction between the first section and the second end.

[0184] 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 conical surface that is inclined from top to bottom in a direction away from the axis of the water stirring member 200, the shape of the limiting protrusion is adapted to the shape between the first section and the second section of the sealing groove 210-4, the outer peripheral surface of the limiting protrusion is in contact with the inner wall of the second section, and the top of the limiting protrusion is in contact with the conical surface between the first section and the second section of the limiting groove.

[0186] 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 .

[0187] In this embodiment, a specific assembly structure of the water stirring member 200 and the stirring shaft 300 is provided. By setting the water stirring portion 240 of the water stirring member 200 to be hollow inside, the purpose of fixing the water stirring member 200 and the stirring shaft 300 by installing the screws 210-7 from top to bottom can be achieved, and the overall weight of the water stirring member 200 is also reduced, thereby further reducing the energy consumption of the motor of the driving device driving the water stirring member 200 to rotate. By setting the sealing cover 210-5, washing water can be prevented from entering the interior of the water stirring member 200, thereby preventing the problem of wire scraps or dirt entering with the washing water and remaining in the interior of the water stirring member 200 and being unable to be cleaned.

[0188] Embodiment 4

[0189] like Figures 12 to 16 As shown, this embodiment is a further limitation of the above-mentioned embodiment four or five: the mounting portion 100-2 includes a mounting groove 100-1 arranged on the inner surface of the barrel bottom 100-3, the assembly portion 210-1 of the water stirring member 200 is at least partially inserted into the mounting groove 100-1, and a water seal structure 500 is arranged between the inner wall of the mounting groove 100-1 and the outer surface of the assembly portion 210-1.

[0190] Specifically, in this embodiment, a mounting through hole that matches the stirring shaft 300 is provided at the center of the bottom surface of the mounting groove 100-1, and the stirring shaft 300 can be rotatably passed through the mounting through hole and plugged and fixed with the assembly portion 210-1 of the water stirring member 200. By providing a water seal structure 500, the washing water is prevented from penetrating into the gap between the mounting groove 100-1 and the assembly portion 210-1 without affecting the relative rotational cooperation between the assembly portion 210-1 and the mounting groove 100-1, thereby preventing the wire scraps or other dirt in the washing water from remaining in the mounting groove 100-1, and effectively avoiding the problem of dirt and dirt hiding between the water stirring member 200 and the bottom 100-3 of the barrel.

[0191] In the specific scheme of this embodiment, the assembly part 210-1 forms the minimum radius section of the water-stirring member 200 below the maximum radius Rmax, and the assembly part 210-1 can be rotatably inserted in the installation groove 100-1, and the upper end of the assembly part 210-1 is not lower than the inner surface of the barrel bottom 100-3 of the outer periphery of the installation groove 100-1.

[0192] As a specific implementation method, Fig.15 As shown, the water seal structure 500 includes an annular first water seal structure 501, which is arranged between the bottom surface of the installation groove 100-1 and the lower end surface of the assembly part 210-1. Specifically, the lower end surface of the first water seal structure 501 is fixed on the bottom surface of the installation groove 100-1, and the upper end surface of the first water seal structure 501 is elastically abutted against the lower end surface of the assembly part 210-1. Preferably, the outer periphery of the first water seal structure 501 is in contact with the groove peripheral wall of the installation groove 100-1.

[0193] More specifically, the upper end surface of the first water seal structure 501 is configured to be sawtooth-shaped, and the upper end surface of the first water seal structure 501 includes a plurality of sawteeth continuously arranged along the radial direction.

[0194] As another specific implementation, Fig.15 As shown, the water seal structure 500 includes an annular second water seal structure 502, which is arranged between the groove peripheral wall of the installation groove 100-1 and the side wall of the assembly part 210-1. Specifically, the outer peripheral surface of the second water seal structure 502 is connected to the groove peripheral wall of the installation groove 100-1, and the inner peripheral surface of the second water seal structure 502 is elastically abutted against the side wall of the assembly part 210-1.

[0195] More specifically, the lower portion of the assembly portion 210-1 is inserted into the mounting groove 100-1, and there are gaps between the lower area of ​​the side wall of the assembly portion 210-1 and the peripheral wall of the mounting groove 100-1, and between the lower end surface of the assembly portion 210-1 and the bottom surface of the mounting groove 100-1. The second water seal structure 502 is at least arranged between the notch of the mounting groove 100-1 and the side wall of the assembly portion 210-1.

[0196] In the above scheme, the second water seal structure 502 is set in an annular shape and is arranged around the lower part of the assembly part 210-1. The second water seal structure 502 can be set only at the notch of the installation groove 100-1, or it can be set in the entire installation groove 100-1. The outer peripheral surface of the second water seal structure 502 is connected to the groove wall of the installation groove 100-1, and the inner peripheral surface of the second water seal structure 502 is elastically abutted against the lower area of ​​the side wall of the assembly part 210-1 through a serrated surface, and the serrated surface includes a plurality of serrations arranged continuously along the axial direction.

[0197] In some possible specific structures, the second water seal structure 502 extends along the axial direction of the installation groove 100-1, and its lower end surface is in contact with the groove bottom of the installation groove 100-1, and its upper end surface is substantially flush with the inner surface of the barrel bottom 100-3. A sealant is provided between the outer peripheral surface of the second water seal structure 502 and the groove wall of the installation groove 100-1, and / or a sealant is provided between the lower end surface of the second water seal structure 502 and the groove bottom surface of the installation groove 100-1.

[0198] Preferably, in some possible specific structures, the lower end of the second water seal structure 502 extends radially toward the central area, and the inner circumference of the second water seal structure 502 at least partially extends between the lower end surface of the assembly part 210-1 and the bottom surface of the installation groove 100-1, so as to further enhance the sealing effect of the gap between the assembly part 210-1 and the barrel bottom 100-3.

[0199] In a further solution, an embedding groove is coaxially arranged at the groove opening of the installation groove 100-1, the diameter of the embedding groove is larger than the diameter of the installation groove 100-1, and the second water seal structure 502 is arranged in the embedding groove, and its lower end surface is in contact with the groove bottom of the embedding groove, and the upper end surface is substantially flush with the inner surface of the barrel bottom 100-3. Preferably, the outer diameter of the second water seal structure 502 is greater than or equal to the inner diameter of the embedding groove, and the inner circumference of the second water seal structure 502 is elastically abutted against the lower area of ​​the side wall of the assembly portion 210-1.

[0200] The "basically flush" mentioned above can mean that the upper end surface of the second water seal structure 502 is flush with the inner surface of the barrel bottom 100-3, or that the upper end surface of the second water seal structure 502 protrudes from the inner surface of the barrel bottom 100-3, or that the upper end surface of the second water seal structure 502 is slightly lower than the inner surface of the barrel bottom 100-3.

[0201] In this embodiment, as a specific implementation method, Fig.15 and Fig.16 As shown, the first water seal structure 501 and the second water seal structure 502 can be provided separately. As another specific implementation, Fig.14 As shown, the first water seal structure 501 and the second water seal structure 502 can also be provided at the same time.

[0202] In a further solution of this embodiment, the inner surface of the barrel bottom 100-3 is provided with an extension wall surrounding the assembly portion 210-1 of the water stirring member 200 and protruding upward, and the inner periphery of the extension wall is coplanar with the groove peripheral wall of the installation groove 100-1.

[0203] Preferably, for a structure in which the first water seal structure 501 is provided alone, the inner periphery of the extension wall is coplanar with the groove peripheral wall of the installation groove 100-1. For a structure in which the second water seal structure 502 is provided, the extension wall is provided around the embedded groove and extends along the axial direction of the washing bucket 100, and the inner periphery of the extension wall is coplanar with the groove peripheral wall of the embedded groove. More specifically, the lower end of the second water seal structure 502 is in contact with the groove bottom of the embedded groove, the upper end surface of the second water seal structure 502 is substantially flush with the upper end surface of the extension wall 100-2, the outer periphery of the second water seal structure 502 is bonded to the groove wall of the embedded groove, and / or the lower end surface of the second water seal structure 502 is bonded to the groove bottom of the embedded groove.

[0204] 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 arranged 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 relatively rotatably to prevent water from entering between the dehydration shaft 110 and the stirring shaft 300.

[0205] 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 .

[0206] As a specific implementation, 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 .

[0207] 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 .

[0208] For the structure 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. For the structure where the upper end surface of the sealing structure 120 is slightly lower than the inner surface of the barrel bottom 100-3, although a concave gap is formed, the concave size of the gap is very small, and the flushing force of the water flow passing through this place during washing is sufficient to remove the lint and dirt there, and no dirt will remain.

[0209] In this embodiment, the lower end of the water stirring rib 220 can extend to the position where the water stirring portion 240 is connected to the assembly portion 210-1, or can extend to the side wall of the assembly portion 210-1. However, it can be understood that since the assembly portion 210-1 is inserted into the mounting groove 100-1 of the barrel bottom 100-3, the lower end of the water stirring rib 220 extends to the lowest point to be flush with the inner surface of the barrel bottom 100-3 at the periphery of the mounting groove 100-1.

[0210] For the solution in which the barrel bottom 100 - 3 is provided with an upwardly protruding extension wall, the lower end of the water-stirring rib 220 extends to a point flush with the upper end surface of the extension wall.

[0211] Preferably, the lower end of the water-stirring rib 220 is spaced from the inner surface of the barrel bottom 100-3 to avoid a narrow gap between the lower end of the water-stirring rib 220 and the barrel bottom 100-3 that is easy to hide dirt. Alternatively, when the lower end of the water-stirring rib 220 is flush with the inner surface of the barrel bottom 100-3, the radial dimension of the water-stirring rib 220 at the lower end is close to zero, and the outer peripheral edge of the water-stirring rib 220 away from the axis is inclined upwardly extended from the lower end toward the outer periphery.

[0212] In this embodiment, a mounting groove 100-1 is provided on the bottom 100-3 of the washing tub 100, which is used to be plugged and matched with the assembly portion 210-1 of the water stirring member 200. The water stirring member 200 and the washing tub 100 are directly mounted and matched, and the relative rotation of the two is more stable when the washing machine is working. By providing a water seal structure 500, the washing water can be prevented from entering the mounting groove 100-1 without affecting the relative rotation of the water stirring member 200 and the washing tub 100, thereby avoiding the problem of dirt and grime between the water stirring member 200 and the washing tub 100, especially inside the mounting groove 100-1.

[0213] Embodiment 5

[0214] like Fig.17 As shown, the difference between this embodiment and the above-mentioned embodiments 1 to 4 is that the washing attachment block 600 includes a first washing attachment block 610 and a second washing attachment block 620, wherein the first washing attachment block 610 is arranged in the first washing space, and the second washing attachment block 620 is arranged in the second washing space.

[0215] As a specific implementation, a plurality of the first washing auxiliary blocks 610 and the second washing auxiliary blocks 620 are both arranged along the circumference of the washing tub 100, and the first washing auxiliary blocks 610 and the second washing auxiliary blocks 620 are staggered in the circumferential direction.

[0216] The first washing block 610 and the second washing block 620 may have the same specific structure, but may have different installation positions. Alternatively, the first washing block 610 and the second washing block 620 may have different specific structures.

[0217] In the above solution, washing attachment blocks 600 are respectively arranged in the first washing space and the second washing space. During the washing process, clothes in different washing spaces can contact different washing attachment blocks 600, thereby providing more diverse clothing movement modes.

[0218] In a further solution of this embodiment, the first washing block 610 and the second washing block 620 both have a certain extension length in the axial direction. The upper end of the second washing block 620 is not higher than the height of the maximum radius Rmax of the water stirring member 200, and at least part of the first washing block 610 extends downward into the second washing space.

[0219] As a specific embodiment, a plurality of first washing blocks 610 of the same structure are arranged in the upper area of ​​the barrel peripheral wall 100-4, and the upper end of each first washing block 610 is located at a height higher than the top of the water stirring member 200, and the lower end of each first washing block 610 is lower than the maximum radius Rmax of the water stirring member 200.

[0220] The specific structure of the first washing block 610 can refer to the specific structure of the washing block 600 in the first embodiment. During washing, the stirring effect of the first washing block 610 on the washing water and the guiding effect on the clothes are similar to those of the washing block 600 in the first embodiment, which will not be repeated here.

[0221] The upper end of the second washing attachment block 620 is not higher than the maximum radius Rmax of the water stirring member 200, that is, the second washing attachment block 620 is completely arranged in the second washing space. Therefore, the second washing attachment block 620 is mainly used to cooperate with the water stirring member 200 to increase the friction on the clothes in the second washing space, thereby enhancing the cleaning effect of the clothes in the second washing space.

[0222] In a specific solution of this embodiment, the upper end of the second washing block 620 is flush or substantially flush with the maximum radius Rmax of the water stirring member 200. In other words, the upper end of the second washing block 620 can be at the same height as the maximum radius Rmax of the water stirring member 200, or slightly lower than the height of the maximum radius Rmax.

[0223] With the above structure, during washing, the clothes move in a circular path in the second washing space: the clothes move along the bottom 100-3 of the washing barrel 100 toward the central area, move upward along the side of the water stirring member 200 in the central area to a point close to the maximum radius Rmax, then move toward the periphery, and after contacting the second washing block 620, move downward along the surface of the second washing block 620, and after falling below the lower end of the second washing block 620, continue to fall along the inner surface of the barrel wall 100-4, and finally return to the bottom of the washing barrel 100.

[0224] If the upper end of the second washing attachment block 620 is significantly lower than the maximum radius Rmax of the water stirring member 200, the clothes will first contact the barrel peripheral wall 100-4 after moving outward near the height of the maximum radius Rmax, and then contact the second washing attachment block 620 during the downward movement. Since the second washing attachment block 620 protrudes from the inner surface of the barrel peripheral wall 100-4, it will cause a certain obstruction to the downward movement of the clothes.

[0225] In the above scheme, the provision of the second washing attachment 620, on the one hand, strengthens the agitation of the washing water in the second washing space, near the barrel wall 100-4, and on the other hand, extends the movement path of the clothes when the clothes fall in the area near the barrel wall 100-4, thereby increasing the friction on the clothes and improving the washing effect in the second washing space.

[0226] In a further solution of this embodiment, the maximum dimension of the first washing auxiliary block 610 along the radial direction of the washing tub 100 is greater than or equal to the maximum dimension of the second washing auxiliary block 620 disposed in the second washing space along the radial direction of the washing tub 100.

[0227] As a specific embodiment, the first washing block 610 and the second washing block 620 have the same structure, and cooperate with the stirring member 200 to stir the washing water in the second washing space, and the water flow intensity of the washing water in the second washing space is higher than the water flow intensity in the first washing space.

[0228] Since the first washing space is located above the second washing space, during the washing process, relatively light and thin clothes are more likely to float up and enter the first washing space for washing, while heavier clothes tend to be washed in the lower second washing space. It is understandable that, under the condition of the required cleaning effect being the same, the washing force required for light and thin clothes is smaller than that for heavy clothes, and if the washing force in the first washing space is too strong, the clothes may be damaged.

[0229] Therefore, by setting the first washing block 610 and the second washing block 620 to have the same structure, a greater water flow intensity can be formed in the second washing space, which can achieve the purpose of washing different types of clothes at the same time and ensure the washing effect in the two washing spaces, while ensuring that light and thin clothes will not be damaged.

[0230] In a detailed structure, the size of the second washing attachment block 620 along the radial direction of the washing tub 100 gradually decreases from top to bottom, and then gradually increases. In this way, when the clothes in the second washing space move downward along the second washing attachment block 620, they first gradually approach the tub peripheral wall 100-4, then gradually move away from the tub peripheral wall 100-4, and finally move toward the second washing attachment block 620 again at the lower end of the second washing attachment block 620, which can more significantly extend the path of the clothes moving downward.

[0231] As another specific embodiment, the protrusion height of the first washing block 610 is greater than that of the second washing block 620 , and the maximum protrusion height of the first washing block 610 is located in the first washing space above the maximum radius Rmax of the water stirring member 200 .

[0232] The above structure is advantageous for controlling the water flow impact force on the first washing attachment 610 to be close to the water flow impact force on the second washing attachment 620, thereby minimizing the difference in the water flow impact force on the washing attachment 600 in the upper and lower parts of the washing tub 100, thereby reducing the torque generated between the upper and lower parts of the washing tub 100, and ensuring the structural stability of the washing tub 100.

[0233] In a preferred solution of this embodiment, the lower end of the second washing block 620 is not lower than the lower end of the assembly portion 210 - 1 of the water agitating member 200 .

[0234] Preferably, the distance between the lower end of the second washing block 620 and the inner surface of the barrel bottom 100-3 needs to be sufficient so that the clothes moving downward along the second washing block 620 can change their direction of movement at the lower end of the second washing block 620, and then can contact the inner surface of the barrel wall 100-4 and continue to move downward along the barrel wall 100-4. In this way, the effect of the second washing block 620 extending the movement path of the clothes is ensured.

[0235] In this embodiment, by respectively arranging the first washing auxiliary block 610 and the second washing auxiliary block 620 at different heights of the barrel peripheral wall 100-4, the water flow intensity in the first washing space and the second washing space can be more specifically enhanced, which is particularly suitable for washing light and thin clothes and heavy clothes at the same time. Different water flow intensities can be provided in different washing spaces, and can be adapted to the characteristics of the clothes washed in the space, so as to provide a better user experience.

[0236] Embodiment 6

[0237] like Fig.18 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that the washing attachment block 600 is only arranged in the first washing space.

[0238] Specifically, in this embodiment, all of the washing attachments 600 are disposed on the barrel peripheral wall 100 - 4 at a height not lower than Rmax of the maximum radius of the water stirring member 200 .

[0239] As a specific embodiment, the washing block 600 has a certain extension length along the axial direction of the washing tub 100, the upper end of the washing block 600 is higher than the top height of the water stirring member 200, and the lower end of the washing block 600 is higher than the maximum radius Rmax of the water stirring member 200, or is flush with the height of the maximum radius Rmax.

[0240] In the solution of this embodiment, in the second washing space, there is no additional protrusion structure on the barrel peripheral wall 100-4, and the washing water is stirred only by the rotation of the water stirring member 200. In the first washing space, since the stirring effect of the water stirring member 200 on the washing water is almost negligible, the washing attachment 600 can be rotated with the washing barrel 100 to strengthen the stirring of the washing water.

[0241] As a specific embodiment, the size of the washing attachment block 620 along the radial direction of the washing tub 100 gradually decreases from top to bottom and then gradually increases, and a concave portion 603 is formed in the middle of the washing attachment block 620. The height of the concave portion 603 is not lower than the top of the water stirring member 200, specifically, not lower than the highest position of the water stirring plate 230.

[0242] More specifically, in the area on the barrel circumferential wall 100 - 4 corresponding to the first washing space, a plurality of washing blocks 600 of the same structure are spaced and evenly distributed along the circumferential direction, so that the inner recesses 603 of each washing block 603 are at the same level.

[0243] In this embodiment, in the first washing space, the washing water generates a circumferentially alternating forward and reverse flow trend as the washing tub 100 rotates forward and reverse alternately, thereby driving the clothes in the first washing space to move forward and reverse alternately in the circumferential direction. By setting the washing attachment 600 to have the above-mentioned specific structure, the clothes can be driven to move in the circumferential direction at a height close to the inner concave portion 603 for washing, that is, the clothes float up compared to the water stirring plate 230. In this way, the problem of clothes directly covering the water stirring plate 230 and increasing the rotation resistance of the water stirring member 200 is avoided.

[0244] In a more preferred solution of this embodiment, the maximum protrusion height of the washing attachment 600 in the upper area of ​​the inner recess 603 is greater than the maximum protrusion height of the lower side of the inner recess 603. Although the stirring force of the water stirring plate 230 of the water stirring member 200 on the washing water in the first washing space is relatively weak, it does not completely play a stirring role. The washing attachment 600 has a greater protrusion height near the barrel mouth, which is conducive to controlling the water flow intensity in the first washing space along the height direction to be relatively close.

[0245] In this embodiment, the washing attachment block 600 is only arranged in the first washing space, which can also enhance the water flow intensity in the first washing space, thereby improving the washing effect of the clothes in the first washing space. By arranging the washing attachment block 600 with a suitable structure, the resistance of the clothes in the first washing space to the rotation of the water stirring member 200 can also be reduced, thereby achieving the effect of reducing the energy consumption of the motor of the driving device.

[0246] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
