Description

Technical Field

[0001] The utility model belongs to the technical field of clothing processing, and in particular relates to a washing barrel assembly, and also relates to a washing device with the washing barrel assembly. 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 washing water in the inner barrel is driven to rotate by the rotation of the pulsator, 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 thread scraps 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 thread scraps are easy to breed bacteria in a humid environment for a long time, which brings a bad user experience to users. 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. In addition, when the above-mentioned pulsator washing machine is washing, all the clothes are located above the pulsator and covered on the surface of the pulsator over a large area. The friction between the pulsator 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 pulsator will also increase the energy consumption required for the drive motor to drive the pulsator to rotate.

[0004] Moreover, for a hole-free barrel washing machine, during dehydration and drainage, debris such as lint can easily clog the drain port of the washing barrel, causing poor drainage.

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

[0042] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0043] 1. The utility model sets the maximum radius of the water stirring member at a certain distance from the bottom of the washing barrel, so that the clothes can be washed below the maximum radius of the water stirring member, so that the surface of the water stirring member below the maximum radius can contact the clothes in the barrel, and the friction between the clothes and the surface of the water stirring member is used to prevent the attachment of line scraps or other dirt on the surface of the water stirring member. By setting the drain port on the washing barrel below the maximum radius of the water stirring member, the friction between the clothes and the inner wall of the washing barrel can be used to clean the drain port, and the problem of dirt and grime easily hidden between the water stirring member and the bottom of the barrel and the easy clogging of the drain port of the washing barrel is effectively avoided, thereby improving the user experience.

[0044] 2. In the present invention, by providing a recessed portion, the centrifugal valve can be easily installed, the overall effect of the washing tub can be improved, and at the same time, the washing surface of the washing tub can be enriched, so that the washing device has a better washing effect.

[0047] 5.

[0067] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0068] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0069] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0070] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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.

[0071] like Figures 1 to 15 As shown, an embodiment of the utility model provides a washing bucket assembly of a washing device, and a washing device having the washing bucket assembly. The washing device can be a washing machine, a washing and drying machine, a care machine, and other washing devices with a clothing washing function.

[0072] 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 also includes a driving device, such as a driving motor, which is transmission-connected to the washing tub 100 and the water stirring member 200, respectively.

[0073] More specifically, the output shaft of the driving device is respectively connected to the stirring shaft 300 and the dehydrating shaft. 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 is fixed to the bottom of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0074] 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 stir the clothes and the washing water in the tub by utilizing the relative rotation trend between the water stirring member 200 and the washing tub 100, and achieve a washing effect on the clothes. 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 uses centrifugal force to spin dry the clothes in the tub.

[0075] However, when the lint and dirt shed during the washing process of the clothes 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 and cause the problem of secondary pollution of the clothes.

[0076] Embodiment 1

[0077] like Figures 1 to 4As shown, this embodiment provides a washing tub assembly and a washing device having the washing tub assembly, which are used to solve the problem that there is a dead corner between the water stirring member 200 and the washing tub 100 where dirt and grime are hidden and difficult to clean.

[0078] Specifically, the washing tub assembly of 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 of the washing tub 100, and has a maximum radius at a certain distance from the bottom of the tub, and the certain distance enables the laundry to be washed below the position where the radius of the water stirring member 200 is the largest.

[0079] The water stirring member 200 and the washing tub 100 described in this embodiment have the above-mentioned matching structure. Compared with the traditional pulsator washing machine or the stirring washing machine with a radial agitator, there is a washing space below the maximum radius of the water stirring member 200. The washing space is composed of the surface of the water stirring member 200 below the maximum radius, the barrel wall of the washing tub 100, and the barrel bottom of the washing tub 100. Clothes can be washed in the washing space, so that the surface of the water stirring member 200 below the maximum radius and the barrel bottom of the washing tub 100 can contact the clothes washed in the barrel. During the washing process, the friction between the clothes and the surface of the water stirring member 200 can prevent the attachment of line scraps or other dirt on the surface of the water stirring member 200, effectively avoiding the problem that dirt is easy to hide between the water stirring member 200 and the barrel bottom and is difficult to clean, thereby improving the user experience.

[0080] It should be noted that, in the embodiment of the present invention, the radius of the water-stirring member 200 refers to the distance from the farthest point from the rotation center to the rotation center on the horizontal cross section of the water-stirring member 200 taken along the horizontal direction.

[0081] Specifically, if the cross section of the water stirring member 200 is circular, the radius is the radius R1 of the circular cross section. If the cross section of the water stirring member 200 is non-circular, the radius is the distance R2 from the farthest point on the cross section to the rotation center.

[0082] As a specific implementation, in this embodiment, the distance h between the maximum radius of the water stirring member 200 and the bottom of the barrel is more than 10 cm, thereby ensuring that the clothes can be washed below the maximum radius.

[0083] In a further solution of this embodiment, the maximum diameter of the water stirring member 200 is lower than the highest water level of the washing tub 100, that is, the maximum radius of the water stirring member 200 is also at a certain distance from the barrel mouth of the washing tub 100 in the height direction, so that the washing water level can be higher than the maximum radius of the water stirring member 200, so that the clothes can be washed above the position of the maximum radius of the water stirring member 200. The highest water level refers to the water level height when the washing tub 100 reaches the maximum water capacity.

[0084] In the above scheme, the washing tub 100 can accommodate clothes for washing both above and below the maximum radius of the water stirring member 200. In this way, the outer surface of the water stirring member 200 can basically contact the clothes to be washed, generating friction with the clothes, and the washing effect can be enhanced by increasing the surface area in contact with the clothes.

[0085] 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, 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 an effect of preventing the clothes from being entangled. If the water level is higher than the height of the maximum radius, although some clothes will be washed above the maximum radius, since the maximum radius of the water stirring member 200 in this embodiment is much smaller than the diameter 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.

[0086] 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.

[0087] In this embodiment, the side of the water stirring member 200 is configured such that as the height of the rotation axis increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 remains constant, or changes gradually or stepwise.

[0088] As a specific embodiment, the water stirring member 200 has a single maximum radius point in the height direction. Further, at least below the maximum radius point, as the height increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 decreases as the height increases.

[0089] It should be noted that the single point with the largest radius may refer to the point with the largest radius of the water-stirring member 200 at a specific height position, or may refer to the point with the largest radius of the water-stirring member 200 within a certain continuous height range.

[0090] In a first specific solution, the largest radius of the water-stirring member 200 is arranged at the top of the water-stirring member 200 , that is, the top surface of the water-stirring member 200 is the cross section with the largest radius.

[0091] In the second specific solution, the maximum radius of the water stirring member 200 is close to the top of the water stirring member 200, but is at a certain distance from the top of the water stirring member 200. Specifically, the upper side surface of the water stirring member 200 at the maximum radius is an upwardly convex curved surface, and the highest point of the curved surface forms the top of the water stirring member 200.

[0092] In the third specific solution, the maximum radius of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0093] In a detailed solution, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 changes continuously in the height direction. Specifically, as the height increases, the diameter of the water stirring member 200 gradually increases from the bottom of the washing tub 100 to the top until the maximum radius is formed, and then the diameter of the water stirring member 200 gradually decreases and finally reaches the top of the water stirring member 200.

[0094] In another detailed solution, the distance between the side of the water stirring member 200 and the barrel wall of the washing tub 100 has a sudden change at at least one height position. Specifically, as the height increases, the diameter of the water stirring member 200 first gradually increases from the barrel bottom of the washing tub 100 upwards, and when it reaches a certain height, the diameter suddenly increases to form the maximum radius, and then the diameter of the water stirring member 200 remains constant within a certain height range, then suddenly decreases, and then continues to gradually decrease, and finally forms the top of the water stirring member 200. In this solution, the distance from the maximum radius on the water stirring member 200 to the barrel bottom of the washing tub 100 refers to the distance from the lowest height in the height range where the diameter of the water stirring member 200 remains constant to the barrel bottom of the washing tub 100.

[0095] As another specific embodiment, the water stirring member 200 has a plurality of spaced maximum radius locations in the axial direction of the washing tub 100. Specifically, as the height increases, the diameter of the water stirring member 200 increases and decreases alternately, each time increasing to the same diameter size and then decreasing, thereby forming a plurality of spaced maximum radius locations.

[0096] In a further solution of this embodiment, the height of the maximum radius of the water stirring member 200 is set between the highest water level and the lowest water level of the washing device. In this way, when the washing device uses different water levels for washing, the rotation of the water stirring member 200 can generate different water flow modes to drive the clothes to move for washing. In particular, as a specific embodiment, below the maximum radius of the water stirring member 200, the clothes can move along a circular path for washing.

[0097] The circular path mentioned above means that the water moves toward the center in the bottom area of ​​the washing tub 100, is lifted by the water stirring member 200 to a position close to the maximum radius of the water stirring member 200, moves toward the periphery, and then falls.

[0098] As a specific solution, the circular path of the clothes moving below the maximum radius of the water stirring member 200 during washing includes: the clothes move along the bottom of the washing tub 100 toward the central area, move upward along the side of the water stirring member 200 in the central area to below the maximum radius and then move toward the periphery, and move downward in the area close to the wall of the washing tub 100.

[0099] In a further solution of this embodiment, the water stirring member 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water stirring rib 220 protruding from the side wall of the support column 210, and the water stirring rib 220 and the protruding direction on the side wall of the support column 210 coincide with the radial direction of the washing tub 100, or form 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. Among them, the support column 210 is used to transmit and connect the driving device of the washing equipment, so that the water stirring member 200 can rotate under the drive of the driving device. The water stirring rib 220 rotates in the washing tub 100 with the water stirring member 200, stirring the clothes and water flow in the tub. The bottom of the washing tub 100, the side walls of the support column 210 and the wall of the washing tub 100 together form a space that can accommodate the laundry during washing, and the laundry can move along the above-mentioned annular path in the space.

[0100] The water-stirring member 200 having the above structure has a side surface including both the side wall of the support column 210 and the surface of the water-stirring rib 220 farthest from the rotation axis, and the radius is the distance from the point on the water-stirring rib 220 farthest from the rotation axis to the rotation center.

[0101] When the washing tub assembly of this embodiment is applied to a washing device, in a specific implementation, when operating at a low water level lower than the maximum radius of the water stirring member 200, the clothes can move in the water along the circular path described above.

[0102] Specifically, during the washing process, relative rotation occurs between the water stirring member 200 and the washing tub 100, and the clothes move toward the central area along the bottom of the washing tub 100 and gather in the space below the maximum radius of the water stirring member 200. In the central area, the clothes are lifted to below the maximum radius along the side walls of the support columns 210 or the outer edges of the water stirring ribs 220, and then move toward the periphery, and then fall to the bottom of the washing tub 100 in the area close to the wall of the washing tub 100, forming a circular motion.

[0103] When operating at a high water level higher than the maximum radius of the water stirring member 200, the clothes move along the above-mentioned circular path in the water in an area below the maximum radius of the water stirring member 200; and in an area above the maximum radius of the water stirring member 200, the clothes move close to the circumferential direction of the washing tub 100.

[0104] Specifically, during the washing process, the water stirring member 200 and the washing tub 100 rotate relative to each other, and in the area below the maximum radius of the water stirring member 200, the movement path of the clothes is substantially the same as the movement path at a low water level. In the area above the maximum radius of the water stirring member 200, the clothes move alternately forward and reverse along the circumference of the washing tub 100 as the water stirring member 200 rotates alternately forward and reverse.

[0105] In the above scheme, when different washing water levels are used, the water stirring member 200 can drive the clothes in the barrel to move in different ways for washing, providing more diverse washing method options. In addition, in the area below the maximum radius of the water stirring member 200, since the clothes move along a circular path, on the one hand, the clothes can be tumbled and the washing effect can be enhanced, and on the other hand, the problem that the existing pulsator washing machine easily drives the clothes to gather at the center, causing the clothes to be entangled, is avoided.

[0106] Regarding the solution in which the maximum radius of the water-stirring member 200 is located at or close to the top of the water-stirring member 200 , as a specific implementation, the maximum radius of the water-stirring member 200 is formed by the upper end of the outer peripheral edge of the water-stirring rib 220 .

[0107] In this embodiment, the washing tub 100 is a tub without holes, which independently holds washing water when washing clothes.

[0108] The washing tub 100 below the maximum radius of the water stirring member 200 is provided with a drain port 100-32 and a centrifugal valve 601 for blocking the drain port 100-32. When the rotation speed of the washing tub 100 is greater than or equal to a predetermined rotation speed, the centrifugal valve 601 opens the drain port 100-32 under the action of centrifugal force.

[0109] By setting the drain outlet 100-32 on the washing tub 100 below the maximum radius of the water stirring member 200, the drain outlet 100-32 can be cleaned by utilizing the friction between the clothes and the inner wall of the washing tub 100, thereby preventing debris such as lint from clogging the drain outlet 100-32, thereby effectively avoiding the problem of easy clogging of the drain outlet 100-32 of the washing tub 100 and improving the user experience.

[0110] By arranging the drain outlet 100-32 on the washing tub 100 below the maximum radius of the water stirring member 200, the clothes can be in contact with the position of the drain outlet 100-32 when the washing machine washes clothes at any water level, thereby preventing debris such as lint from accumulating at the drain outlet 100-32 and preventing the drain outlet 100-32 from being blocked.

[0111] Specifically, since the clothes move along a circular path below the maximum radius of the water-stirring member 200 during washing, the circular path of movement includes: the clothes move along the bottom of the washing tub 100 toward the central area, move upward along the side of the water-stirring member 200 in the central area to below the maximum radius and then move toward the periphery, and move downward in an area close to the wall of the washing tub 100, so that the clothes can fully contact the bottom and wall of the washing tub 100 below the maximum radius of the water-stirring member 200, so that when the washing device washes clothes at any water level, the clothes can contact and rub against the position at the drain outlet 100-32, thereby avoiding blockage of the drain outlet 100-32.

[0112] In this embodiment, the working mode of the centrifugal valve 601 is that during the normal washing process of the washing device, the centrifugal valve 601 blocks the drain port 100-32. When the washing barrel 100 of the washing device rotates at high speed, the centrifugal valve 601 opens the drain port 100-32 due to the centrifugal force.

[0113] In this embodiment, the predetermined rotation speed is a preset value that is greater than the washing rotation speed of the washing tub 100 and less than or equal to the dehydration rotation speed of the washing tub 100 .

[0114] In this embodiment, the centrifugal valve 601 is arranged outside the washing tub 100, and the drain outlet 100-32 is blocked from one end where the drain outlet 100-32 is connected to the outside of the washing tub 100. Thus, the centrifugal valve 601 can be prevented from occupying the internal space of the washing tub 100 and scratching clothes. Moreover, the cleaning effect of the clothes on the drain outlet 100-32 of the washing tub 100 can be improved.

[0115] like Figure 1 As shown, in this embodiment, the drain port 100 - 32 is arranged on the barrel wall below the maximum radius of the water stirring member 200 , and the centrifugal valve 601 is arranged on the barrel wall on a side away from the water stirring member 200 .

[0116] The centrifugal valve 601 includes a movable rod 601-1 and an elastic component 601-3. Specifically, the movable rod 601-1 is arranged on the washing bucket 100, and the first end of the movable rod 601-1 is hinged to the washing bucket 100. A sealing portion 601-4 corresponding to the drain outlet 100-32 is arranged in the middle of the movable rod 601-1, and a counterweight block 601-2 is arranged at the second end of the movable rod 601-1. The driving component is used to drive the movable rod 601-1 to rotate toward the side close to the drain outlet 100-32.

[0117] In this embodiment, the first end of the movable rod 601-1 is hinged on the barrel wall of the washing barrel 100, and the elastic component 601-3 is arranged on the side of the movable rod 601-1 away from the drain outlet 100-32 and abuts against the movable rod 601-1. Under the action of the elastic component 601-3, the movable rod 601-1 rotates toward the drain outlet 100-32, so that the sealing part 601-4 abuts against the barrel wall at the drain outlet 100-32, thereby achieving sealing of the drain outlet 100-32. When the rotation speed of the washing barrel 100 reaches the set rotation speed, the centrifugal force exerted on the counterweight block 601-2 is greater than the elastic force applied by the elastic component 601-3 to the movable rod 601-1, and the counterweight block 601-2 shrinks, causing the movable rod 601-1 to rotate away from the drain outlet 100-32 under the drive of the counterweight block 601-2, and the sealing part 601-4 is separated from the barrel wall at the drain outlet 100-32, thereby opening the drain outlet 100-32.

[0118] In some preferred embodiments of the present invention, the first end of the movable rod 601 - 1 is hinged to the washing tub 100 via a rotating shaft, and the movable rod 601 - 1 rotates around the axis of the rotating shaft, and the axis of the rotating shaft is parallel to the rotation center of the washing tub 100 .

[0119] Preferably, in this embodiment, the drain outlet 100-32 is protruding toward the outside of the washing barrel 100, and the sealing portion 601-4 includes a groove-type sealing portion, which is sleeved on the drain outlet 100-32 and elastically abuts against the outer peripheral wall of the drain outlet 100-32; and / or, the sealing portion 601-4 includes a columnar sealing portion, which is inserted into the drain outlet 100-32 and elastically abuts against the inner wall of the drain outlet 100-32.

[0120] like Figure 2 and Figure 4 As shown, in this embodiment, the barrel wall at the drain outlet 100-32 protrudes and extends outside the washing barrel 100, forming a boss with a gradually decreasing diameter on the barrel wall, and the shape of the groove-shaped sealing portion is adapted to the shape of the boss-shaped drain outlet 100-32, and at least the end of the groove-shaped sealing portion is made of a soft material such as rubber. The sealing groove 210-4 abuts against the outer peripheral wall of the drain outlet 100-32 and / or the barrel wall of the washing barrel 100 around the drain outlet 100-32 to achieve sealing of the drain outlet 100-32.

[0121] Preferably, in some possible embodiments, the bottom of the groove of the groove-type sealing part is made of rubber, or a rubber pad is provided on the bottom of the groove of the groove-type sealing part, and the end of the drain port 100-32 elastically abuts against the bottom of the groove of the groove-type sealing part.

[0122] In some possible embodiments, the cylindrical sealing portion protrudes from the middle of the movable rod 601-1, and the diameter of the cylindrical sealing portion gradually decreases in the direction away from the movable rod 601-1. The movable rod 601-1 rotates toward the drain outlet 100-32 under the action of the elastic component 601-3, so that the cylindrical sealing portion on the movable rod 601-1 is inserted into the drain outlet 100-32, and the side wall of the cylindrical sealing portion elastically abuts against the inner wall of the drain outlet 100-32 to achieve sealing of the drain outlet 100-32.

[0123] In some possible embodiments, the sealing portion 601 - 4 includes a groove-type sealing portion and a columnar sealing portion, and the columnar sealing portion is disposed on the groove bottom of the groove-type sealing portion.

[0124] like Figure 4As shown, in this embodiment, the elastic component 601-3 includes a guide cylinder 601-31, a sliding column 601-32 and a compression spring 601-33. Specifically, the guide cylinder 601-31 is arranged on the washing bucket 100, and an opening is arranged at one end of the guide cylinder 601-31 facing the movable rod 601-1. The sliding column 601-32 is arranged in the guide cylinder 601-31 and slides with the guide cylinder 601-31. The sliding column 601-32 at least partially extends to the outside of the opening of the guide cylinder 601-31 and abuts against the movable rod 601-1; a compression spring 601-33 is arranged between the end of the sliding column 601-32 away from the movable rod 601-1 and the guide cylinder 601-31.

[0125] The sliding column 601-32 extends to one end outside the guide cylinder 601-31 and slides with the movable rod 601-1. Initially, the sliding column 601-32 slides toward the outside of the guide cylinder 601-31 under the action of the compression spring 601-33, pressing the movable rod 601-1 against the barrel wall, so that the sealing part 601-4 on the movable rod 601-1 blocks the drain outlet 100-32; when the rotation speed of the washing barrel 100 reaches the set rotation speed, the movable rod 601-1 rotates away from the drain outlet 100-32 under the action of centrifugal force, so that the sealing part 601-4 is separated from the drain outlet 100-32, and the drain outlet 100-32 is opened. During this process, the movable rod 601-1 and the sliding column 601-32 slide relative to each other, so that the drain outlet 100-32 is smoothly opened.

[0126] Preferably, in this embodiment, the end portion of the sliding column 601 - 32 extending outside the guide cylinder 601 - 31 is configured as a spherical surface or an arcuate surface to improve the smoothness of the rotation of the movable rod 601 - 1 .

[0127] Preferably, the elastic component 601 - 3 is coaxially arranged with the drain outlet 100 - 32 to improve the sealing effect of the drain outlet 100 - 32.

[0128] Preferably, one end of the guide cylinder 601 - 31 away from the movable rod 601 - 1 is closed and connected to the barrel wall.

By providing the recessed portion 100-4, it is convenient to install the centrifugal valve 601, which can improve the overall effect of the washing barrel 100, and at the same time, it can enrich the washing surface 100-31 of the washing barrel 100, so that the washing device has a better washing effect.

[0130] Specifically, in this embodiment, the recessed portion 100-4 includes a first wall 100-41 and a second wall 100-42 which are connected to each other. The first wall 100-41 is arranged at the top of the recessed portion 100-4, and the end away from the axis of the washing tub 100 is connected to the tub wall. The second wall 100-42 extends downward from the end of the first wall 100-41 close to the axis of the washing tub 100 and is connected to the bottom of the tub. The first wall 100-41 and the second wall 100-42 together constitute the recessed portion 100-4.

[0131] In this embodiment, the second wall 100-42 may be an arc convex to the inside of the washing tub 100, an arc convex to the outside of the washing tub 100, or a U-shaped opening disposed outside the washing tub 100, and the bottom of the U-shaped second wall 100-42 may be an arc convex to the inside of the washing tub 100, or a flat surface. The first wall 100-41 of the recessed portion 100-4 is adapted to the second wall 100-42, and the first wall 100-41 extends from the upper edge of the second wall 100-42 in a direction away from the axis of the washing tub 100, and is connected to the tub wall.

[0132] In this embodiment, the second wall 100 - 42 is arranged at an angle with the bottom of the washing tub 100 , and the angle is greater than 0° and less than or equal to 90°.

[0133] In this embodiment, the drain port 100 - 32 is disposed on the second wall 100 - 42 .

Further preferably, the first wall 100-41 extends upwardly in a direction away from the axis of the washing tub 100. Thus, it is possible to prevent the washing water from accumulating on the first wall 100-41 of the recessed portion 100-4.

[0135] Preferably, in this embodiment, the second wall 100-42 of the recessed portion 100-4 is at least partially configured as a plane, and the drain outlet 100-32 is disposed on the plane of the second wall 100-42, so that the swing rod can seal the drain outlet 100-32.

[0136] Preferably, in this embodiment, the recessed portion 100 - 4 extends toward both sides of the washing tub 100 in a horizontal direction, the extending direction of the recessed portion 100 - 4 is a straight line, and the second wall 100 - 42 is a vertical plane as a whole.

[0137] In some embodiments of the present invention, the drain port 100-32 is provided as one, and is blocked by a centrifugal valve 601. Preferably, the drain port 100-32 is provided in the middle of the second wall 100-42.

[0138] In some possible embodiments of the present invention, a plurality of drain ports 100 - 32 are provided, and a centrifugal valve 601 is correspondingly provided at each drain port 100 - 32 , and each drain port 100 - 32 is sealed by a centrifugal valve 601 .

[0139] In some possible embodiments of the present invention, there are multiple drain ports 100-32, and two or more drain ports 100-32 are blocked simultaneously by one centrifugal valve 601. In this embodiment, two or more sealing parts 601-4 are respectively provided on the movable rod 601-1 of each centrifugal valve 601, and each sealing part 601-4 is respectively used to seal a corresponding drain port 100-32.

[0140] Preferably, in this embodiment, when the centrifugal valve 601 is provided in plurality, the number of the centrifugal valve 601 is preferably set to an even number, and the plurality of centrifugal valves 601 are symmetrically arranged on the second wall 100 - 42 to reduce the eccentric force of the washing tub 100 rotating.

[0141] In this embodiment, the recessed portion 100-4 extends along a horizontal straight line, and the recessed portion 100-4 is symmetrical with respect to a vertical line between the center of the recessed portion 100-4 and the axis of the washing bucket 100, that is, the recessed portion 100-4 is vertically bisected by a diameter of the washing bucket 100 which is perpendicular to its extension direction.

[0142] There are multiple centrifugal valves 601 , which are arranged symmetrically with respect to a vertical line between the center of the recessed portion 100 - 4 and the axis of the washing tub 100 .

[0143] Preferably, in this embodiment, there are multiple recessed portions 100-4, which are evenly arranged along the circumference of the washing tub 100, and each of the recessed portions 100-4 is respectively provided with one or more centrifugal valves 601, and each of the centrifugal valves 601 is symmetrically arranged along the axis of the washing tub 100.

[0144] Preferably, in this embodiment, a plurality of centrifugal valves 601 are respectively provided on each of the recessed portions 100-4, and the centrifugal valves 601 are symmetrically arranged relative to the vertical line between the center of the recessed portion 100-4 and the axis of the washing bucket 100, and the opening and closing ends of the centrifugal valves 601 are oriented toward the vertical line between the center of the recessed portion 100-4 and the axis of the washing bucket 100.

[0145] In a specific embodiment of the utility model, the recessed portion 100-4 is set in two, and two drain outlets 100-32 are respectively arranged on the second walls 100-42 of the two recessed portions 100-4. The two drain outlets 100-32 are symmetrical with respect to the vertical line between the center of the recessed portion 100-4 and the axis of the washing barrel 100. Two centrifugal valves 601 are respectively arranged in each of the recessed portions 100-4, and each centrifugal valve 601 is respectively used to seal each drain outlet 100-32.

[0146] In this embodiment, the two centrifugal valves 601 on the same recessed portion 100-4 are symmetrical with respect to the vertical line between the center of the recessed portion 100-4 and the axis of the washing bucket 100, and the opening and closing ends of the two centrifugal valves 601 are both oriented toward the vertical line between the center of the recessed portion 100-4 and the axis of the washing bucket 100, that is, the opening and closing ends of the two centrifugal valves 601 on the same recessed portion 100-4 are relatively arranged.

[0147] Specifically, the first end of the movable rod 601-1 of the centrifugal valve 601 is connected to the first wall 100-41 of the recessed portion 100-4 through a rotating shaft, the upper end of the rotating shaft is connected to the first wall 100-41, and extends vertically downward from the first wall 100-41, the first end of the movable rod 601-1 is connected to the rotating shaft through a bushing, and the first end of the movable rod 601-1 is axially limited with the rotating shaft.

[0148] The first end of the movable rod 601-1 is connected to the end of the first wall 100-41 of the recessed portion 100-4 on a side close to the second wall 100-42, and the movable rod 601-1 is bent at a position close to the rotation center of the movable rod 601-1 toward the second wall 100-42, and the bent portion is bent away from the rotation center of the movable rod 601-1 toward the side close to the second wall 100-42, and the movable rod 601-1 on the side away from the rotation center of the movable rod 601-1 is in contact with the second wall 100-42. The bent portion is arranged between the drain outlet 100-32 and the rotation center of the bent portion.

[0149] In this embodiment, by setting the movable rod 601-1 to be hinged with the end of the first wall 100-41 and providing a bending portion on the movable rod 601-1, the movable rod 601-1 can have a larger rotation angle without exceeding the range of the recessed portion 100-4, thereby improving the smoothness of drainage.

[0150] Preferably, Figure 1 As shown, in this embodiment, a water baffle 100 - 5 is further provided on the washing tub 100 , and the water baffle 100 - 5 is used to guide the washing water discharged from the drainage port 100 - 32 to the bottom of the washing tub 100 .

[0151] The water baffle 100-5 is arranged on the side of the drain outlet 100-32 away from the axis of the washing tub 100, one end of which is connected to the tub wall and the other end extends downward, which can stop and gather the washing water discharged from the drain outlet 100-32 to prevent the washing water from splashing everywhere.

[0152] Specifically, the water baffle 100 - 5 is disposed on a side of the recessed portion 100 - 4 away from the axis of the washing tub 100 , and extends downward from the top of the recessed portion 100 - 4 .

[0153] Preferably, in this embodiment, the water baffle 100-5 extends along the circumference of the washing tub 100, the upper end of the water baffle 100-5 is connected to the side of the first wall 100-41 of the recessed portion 100-4 away from the axis of the washing tub 100, and the length direction of the water baffle 100-5 extends along the edge of the first wall 100-41 away from the axis of the washing tub 100. Preferably, the water baffle 100-5 extends vertically downward.

[0154] The movable rod 601 - 1 of the centrifugal valve 601 rotates between the second wall 100 - 42 and the water retaining plate 100 - 5 .

[0155] Preferably, the elastic component 601 - 3 of the centrifugal valve 601 is disposed on the water retaining plate 100 - 5 and is coaxial with the drain outlet 100 - 32 .

[0156] In this embodiment, the water stirring member 200 has a maximum radius along the radial direction of the washing tub 100 at a certain distance from the inner surface of the bottom of the tub, and a first guide surface 213 is formed on the lower side thereof, extending from the area close to the axis toward the periphery, for guiding the clothes below the area to move toward the periphery along the first guide surface 213 during washing; a second guide surface 214 is formed below the first guide surface 213, extending upward, for guiding the clothes to move along the second guide surface 214 toward the first guide surface 213 during washing.

[0157] Specifically, in this embodiment, the water stirring component 200 includes a support column 210 coaxially arranged with the washing tub 100, and a water stirring rib 220 protruding from the side wall of the support column 210; clothes can be washed in a space jointly formed by the bottom of the washing tub 100, the side wall of the support column 210 and the wall of the washing tub 100.

[0158] The support column 210 is arranged to change its diameter along the axial direction below the maximum diameter of the water-stirring member 200, and includes a first extension section 211 and a second extension section 212 that are connected; the side wall of the first extension section 211 extends upward from the bottom of the washing tub 100, and is used to guide the clothes to move toward the maximum diameter of the water-stirring member 200 during washing; the side wall of the second extension section 212 extends from the upper end of the first extension section 211 toward the periphery and tilts upward, extending to the height of the maximum diameter of the water-stirring member 200, and is used to guide the clothes below this location to move toward the periphery during washing.

[0159] The side wall of the first extension section 211 constitutes the second guiding surface 214 , and the side wall of the second extension section 212 constitutes the first guiding surface 213 .

[0160] 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 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 wall 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 tangled is reduced.

[0161] Preferably, in this embodiment, the water stirring rib 220 has a certain extension length along the axial direction of the washing tub 100 , extending from the second guide surface 214 to the first guide surface 213 .

[0162] In this embodiment, a plurality of water-stirring ribs 220 are arranged at intervals along the circumference of the support column 210. The interval angle between two adjacent water-stirring ribs 220 allows the clothes to be washed in the interval area between the two adjacent water-stirring ribs 220, avoiding dead corners where dirt is easily accumulated.

[0163] Preferably, the distance between the side of the water-stirring rib 220 away from the axis of the water-stirring member 200 and the axis of the water-stirring member 200 increases with increasing height.

[0164] 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.

[0165] It can be understood that the clothes moving along the bottom of the barrel toward the central area during washing 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, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom of the barrel along the wall of the washing barrel 100.

[0166] In the present embodiment, the washing water in the washing tub 100 moves toward the central area along the bottom of the washing tub 100 while rotating around the rotation center of the water stirring member 200 under the stirring of the water stirring member 200, then moves upward along the second guide surface 214 to the first guide surface 213, moves toward the periphery under the guidance of the first guide surface 213, and then falls in an area close to the wall of the washing tub 100.

[0167] 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.

[0168] 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.

[0169] In this embodiment, by designing the specific structure of the water-stirring component 200, the side wall of the support column 210 is used to form a guiding surface that can guide the movement of clothes. Combined with the specific structure of the water-stirring rib 220, the effect of driving the clothes to move along a circular path below the maximum radius Rmax is better.

[0170] Preferably, in some specific embodiments of the present invention, the driving device of the washing equipment is respectively connected to the washing tub 100 and the water stirring member 200 for driving the washing tub 100 and the water stirring member 200 to rotate.

[0171] More specifically, the output shaft of the driving device is respectively connected to the stirring shaft 300 and the dehydrating shaft. 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 is fixed to the bottom of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0172] During washing, the driving device drives the stirring shaft 300 and the dehydrating shaft to rotate simultaneously or alternately, and then drives the water stirring member 200 and the washing tub 100 to rotate simultaneously or alternately, and utilizes the relative rotation between the water stirring member 200 and the washing tub 100 to stir the clothes and the washing water in the tub, so as to achieve a washing effect on the clothes. During dehydration, the driving device drives the stirring shaft 300 and the dehydrating shaft to rotate synchronously at high speed, and then drives the water stirring member 200 and the washing tub 100 to rotate synchronously at high speed, and utilizes centrifugal force to spin dry the clothes in the tub.

[0173] More specifically, in this embodiment, the driving device drives the washing tub 100 and the water stirring member 200 through a deceleration clutch device. The deceleration clutch device includes a stirring shaft 300 connected to the water stirring member 200, and a dehydration shaft connected to the washing tub 100. During washing, the deceleration clutch device performs a washing operation. Under the drive of the driving device, the stirring shaft 300 and the dehydration shaft rotate simultaneously or alternately. In the case of simultaneous rotation, at least one of the rotation direction and the rotation speed is different, thereby driving the water stirring member 200 and the washing tub 100 to generate relative rotation for washing. During dehydration, the deceleration clutch device performs a dehydration operation. Under the drive of the driving device, the stirring shaft 300 and the dehydration shaft rotate synchronously at a high speed, thereby driving the water stirring member 200 and the washing tub 100 to rotate synchronously at a high speed for dehydration.

[0174] In the above scheme, the specific structure of the deceleration clutch device can adopt the structure of the deceleration clutch in the existing dual-power washing equipment.

[0175] In this embodiment, the relative rotation between the washing tub 100 and the water stirring member 200 during the washing process can be used to drive the clothes in the tub to move in an area below the maximum radius Rmax of the water stirring member 200 for washing. On the one hand, the clothes can fully contact the outer surface of the water stirring member 200 and the inner wall of the washing tub 100 below the area of ​​the maximum radius Rmax, effectively avoiding the problem that dirt and grime are easily hidden between the water stirring member 200 and the bottom of the tub and are difficult to clean, thereby improving the user experience. On the other hand, part or all of the clothes are below the maximum radius Rmax of the water stirring member 200 during washing, and will not cover a large area above the water stirring member 200, which can significantly reduce the resistance of the clothes to the rotation of the water stirring member 200, thereby helping to reduce the energy consumption of the motor of the driving device driving the water stirring member 200 to rotate.

[0176] As a specific implementation, during the washing process, the driving device drives the washing tub 100 and the water stirring member 200 to rotate in opposite directions to perform washing.

[0177] Specifically, during washing, the driving device drives the water stirring member 200 to rotate alternately forward and reversely, and at the same time drives the washing tub 100 to rotate alternately forward and reversely in the opposite direction of the water stirring member 200. When the water stirring member 200 rotates clockwise, the washing tub 100 rotates counterclockwise; conversely, when the water stirring member 200 rotates counterclockwise, the washing tub 100 rotates clockwise.

[0178] In the above solution, when the washing tub 100 and the water stirring member 200 rotate in opposite directions, the rotation speeds of the two can be the same or different. In the preferred solution, the washing tub 100 and the water stirring member 200 rotate in opposite directions at different rotation speeds, wherein the rotation speed of the water stirring member 200 is greater than the rotation speed of the washing tub 100.

[0179] As another specific embodiment, during the washing process, the driving device drives the washing tub 100 and the water stirring member 200 to rotate in the same direction at different speeds for washing. For example, the speed of the washing tub 100 is less than the speed of the water stirring member 200. In this way, relative rotation can also be formed between the washing tub 100 and the water stirring member 200.

[0180] Similar to the previous embodiment, the washing tub 100 and the water stirring member 200 also rotate alternately in positive and negative directions during the washing process. That is, the washing tub 100 and the water stirring member 200 rotate clockwise at different speeds at the same time, and then rotate counterclockwise at the same time, in a reciprocating cycle.

[0181] As another specific embodiment, during the washing process, the driving device drives the washing tub 100 and the water stirring member 200 to rotate alternately, that is, when the water stirring member 200 is driven to rotate, the washing tub 100 remains stationary, and when the washing tub 100 is driven to rotate, the water stirring member 200 remains stationary. In this way, relative rotation can also be formed between the washing tub 100 and the water stirring member 200.

[0182] Embodiment 2

[0183] like Figures 5 to 8 As shown, in the embodiment of the utility model, a washing tub assembly of a washing device is introduced. The washing tub assembly includes a washing tub 100 and a water stirring member 200 installed on the washing tub 100. When the washing device is working, the washing water in the washing tub 100 is driven to rotate by the rotation of the water stirring member 200, so as to wash the clothes in the washing tub 100.

[0184] In this embodiment, the washing tub 100 is a tub without holes.

[0185] In this embodiment, when the water stirring member 200 is installed, a gap is formed between the bottom of the water stirring member 200 and the bottom of the washing tub 100. During the washing process, dirt and impurities such as lint on the clothes are easily accumulated in the gap between the bottom of the water stirring member 200 and the bottom of the washing tub. The area in the gap does not contact the clothes, so the impurities in the gap are in a state of long-term accumulation, which cannot be effectively cleaned by simply flushing, and are easy to breed bacteria, causing contamination to the clothes with the washing water.

[0186] In this embodiment, a water seal structure 500 is provided between the water stirring member 200 and the bottom of the washing tub 100. The water seal structure 500 is used to prevent washing water from entering the gap between the water stirring member 200 and the bottom of the washing tub 100, thereby preventing impurities such as dirt and lint dropped from the clothes from entering and accumulating in the gap between the water stirring member 200 and the bottom of the washing tub, thereby improving the cleanliness of the space in the washing tub 100 that is in contact with the washing water, thereby improving the cleaning effect on the clothes.

[0187] In this embodiment, the water stirring member 200 extends axially along the washing tub 100, and the lower end of the water stirring member 200 is plugged and rotatably engaged with the inner surface of the bottom of the washing tub 100, and a water seal structure 500 is provided between the bottom of the tub where the clothes can reach, closest to its center, and the lower end circumferential surface of the water stirring member 200.

[0188] In the present embodiment, a water-stirring member 200 is provided to extend along the axial direction of the washing tub 100, and a water seal structure 500 is provided between the bottom of the tub where the clothes can reach and the circumferential surface of the lower end of the water-stirring member 200. The bottom of the washing tub 100 outside the water seal structure 500 can be in contact with the clothes, and the friction between the clothes and the inner surface of the bottom of the tub is utilized to prevent lint or other dirt from adhering to the inner surface of the bottom of the tub. At the same time, the water seal structure 500 can prevent the washing water from flushing the dirt to a position where the clothes cannot reach, thereby effectively avoiding the problem of dirt and grime being easily hidden and difficult to clean between the water-stirring member 200 and the bottom of the tub, thereby improving the user experience.

[0189] In this embodiment, the water stirring member 200 extends upward from the bottom of the washing tub 100, and includes a support column 210 and a water stirring rib 220 arranged on the support column 210. The support column 210 extends along the axial direction of the washing tub 100, and the water stirring rib 220 is arranged on the circumferential side of the support column 210 and extends along the length direction of the support column 210.

The clothes in the washing tub 100 are arranged around the support column 210. During the rotation of the water stirring member 200, the clothes can contact the circumferential side of the support column 210 and the barrel bottom of the washing tub 100 outside the support column 210. The friction between the clothes and the support column 210 and between the clothes and the part of the barrel bottom placed on the outer periphery of the support column 210 is used to prevent lint or other dirt from adhering to the circumferential side of the support column 210 and the barrel bottom outside the support column 210, which effectively avoids the problem that dirt is easy to hide between the water stirring member 200 and the barrel bottom and is difficult to clean, thereby improving the user experience.

[0237] Embodiment 3

[0238] like Figures 9 to 12As shown, in the embodiment of the utility model, a washing device is introduced, which includes a washing tub 100 and a water stirring member 200 installed on the washing tub 100. When the washing device is working, the washing water in the washing tub 100 is driven to rotate by the rotation of the water stirring member 200, so as to wash the clothes in the washing tub 100.

[0239] In this embodiment, the washing tub 100 is a tub without holes.

[0240] In this embodiment, when the water stirring member 200 is installed, a gap is formed between the bottom of the water stirring member 200 and the bottom of the washing tub 100. During the washing process, dirt and impurities such as lint on the clothes are easily accumulated in the gap between the bottom of the water stirring member 200 and the bottom of the washing tub. The area in the gap does not contact the clothes, so the impurities in the gap are in a state of long-term accumulation, which cannot be effectively cleaned by simply flushing, and are easy to breed bacteria, causing contamination to the clothes with the washing water.

[0241] In this embodiment, a water seal structure 500 is provided between the water stirring member 200 and the bottom of the washing tub 100. The water seal structure 500 is used to prevent washing water from entering the gap between the water stirring member 200 and the bottom of the washing tub 100, thereby preventing impurities such as dirt and lint dropped from the clothes from entering and accumulating in the gap between the water stirring member 200 and the bottom of the washing tub, thereby improving the cleanliness of the space in the washing tub 100 that is in contact with the washing water, thereby improving the cleaning effect on the clothes.

[0268] Specifically, for the inner surface of the barrel bottom provided with an extension wall 100 - 2 , the lower end of the water stirring rib extends to a position flush with the upper end surface of the extension wall.

[0269] Preferably, in this embodiment, the lower end of the water-stirring rib 220 is spaced from the bottom of the barrel so that clothes can enter the space between the lower end of the water-stirring rib 220 and the bottom of the barrel, and clothes can contact the lower end circumference of the support column 210.

[0271] Specifically, a spline groove 210-6 is coaxially arranged at the bottom of the water-stirring member 200, and the spline groove 210-6 is at least partially sleeved on the end of the stirring shaft 300 and is key-connected to the stirring shaft 300.

When the water stirring member 200 is installed, the insert 401 is inserted into the mounting cavity 210-2, and the axial positioning of the insert 401 is achieved by the locking assembly. When the water stirring member 200 is disassembled, the unlocking assembly is operated to make the locking assembly release the lock on the insert 401, so that the water stirring member 200 can be detached from the upper end of the stirring shaft 300.

[0274] The water stirring member 200 and the stirring shaft 300 are axially positioned by a screw 210-7. Specifically, an assembly hole 210-3 is provided on the water stirring member 200, which penetrates the water stirring member 200 axially.

[0276] In this embodiment, a sealing groove 210 - 4 is provided at the top of the water stirring member 200 , and a sealing cover 210 - 5 for sealing the upper end of the water stirring member 200 is provided at the sealing groove 210 - 4 to prevent washing water from entering the interior of the water stirring member 200 .

[0277] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion. The flat plate portion covers the notch of the sealing groove 210-4 and is embedded in the top of the water stirring member 200.

Preferably, the sealing ridge extends along the circumference of the plug-in portion and is provided with multiple circles arranged at intervals along the axial direction of the plug-in portion.

[0282] 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 .

[0283] Preferably, in this embodiment, the water stirring member 200 has a maximum radius along the radial direction of the washing tub 100 at a certain distance from the bottom surface of the washing tub 100, and a guide surface extending toward the periphery is formed there, for guiding the clothes below thereto move toward the periphery along the guide surface during washing.

[0284] Embodiment 4

[0285] like Fig.13 and Fig.14 As shown, this embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub assembly. In this embodiment, below the maximum radius of the water stirring member 200, the distance between the side wall of the support column 210 and the tub wall of the washing tub 100 decreases with increasing height.

[0286] It should be noted that in the embodiment of the present utility model, the maximum radius of the water-stirring component 200 refers to the maximum radius of the horizontal cross-section of the water-stirring component 200, and the radius of the horizontal cross-section of the water-stirring component 200 refers to the distance from the farthest point from the center of rotation to the center of rotation on the horizontal cross-section of the water-stirring component 200 taken along the horizontal direction.

[0287] Specifically, if the horizontal cross section of the agitating member 200 is circular, the radius is the radius R1 of the circular cross section. If the horizontal cross section of the agitating member 200 is non-circular, the radius is the distance R2 from the farthest point on the cross section to the rotation center.

[0288] In this embodiment, a protruding water stirring rib 220 is provided on the side wall of the support column 210, and the radial dimension of the water stirring rib 220 along the washing tub 100 may remain constant as the height increases, or may change gradually or stepwise. As the distance between the side wall of the support column 210 and the wall of the washing tub 100 decreases as the height increases, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 shows a trend of decreasing as the height increases.

[0289] In the above structure, the radius of any horizontal cross section of the water-stirring member 200 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 cross section.

[0290] 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 member 200 may not form a regular geometric shape, but the radius of the horizontal cross section of the water stirring member 200 is still the distance from the farthest end of the water stirring ribs from the axis to the central axis on the cross section.

[0291] In this embodiment, the clothes can also be washed in the space formed by the bottom of the washing tub 100, the side wall of the support column 210 and the wall of the washing tub 100.

[0292] In a specific solution of this embodiment, the support column 210 includes a first extension section 211 and a second extension section 212 which are arranged below and connected to the maximum radius of the water stirring member 200. The side wall of the first extension section 211 extends upwardly and tilts from the bottom of the washing tub 100, gradually approaching the tub wall of the washing tub 100. 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 to the height of the maximum radius of the water stirring member 200, so that the clothes can be washed below the side wall of the second extension section 212 and move toward the periphery along the side wall of the second extension section 212.

[0293] 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 has a larger angle with the vertical direction than the side wall of the first extension section 211, and as the height increases, the 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.

[0294] In this embodiment, the upper end of the support column 210 is also provided with a water stirring tray 230, and specifically, the upper end of the second extension section 212 is connected to the lower surface of the water stirring tray 230. The support column 210 of the water stirring member 200 has the above structure, which effectively reduces the problem of a cleaning dead corner between the upper end of the support column 210 and the lower surface of the water stirring tray 230 that cannot be touched by clothes.

[0295] 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 .

[0296] In the preferred embodiment of this embodiment, Fig.14 As shown, the upper side surface of the water stirring tray 230 is a curved surface with a middle area higher than the outer peripheral area, and a protruding stirring portion 231 is provided on the curved surface. When the water level in the washing tub 100 is higher than the top of the water stirring tray 230, the stirring portion 231 rotates with the water stirring member 200 to stir the washing water above the water stirring tray 230, and can also rub the clothes above the water stirring tray 230, thereby enhancing the washing effect.

[0297] Further, in this embodiment, the side wall of the second extension section 212 forms a first guide surface 213, which is used to guide the clothes below the first guide surface 213 to move toward the periphery during washing. The side wall of the first extension section 211 forms a second guide surface 214, which is used to guide the clothes to rise to the first guide surface 213 along the second guide surface 214 during washing.

[0298] Specifically, when washing, the washing device using the washing tub assembly described in this embodiment rotates relative to the washing tub 100, so that the clothes move along the bottom of the washing tub 100 toward the central area, then move upward along the first guide surface 213 to the second guide surface 214, move toward the periphery under the guidance of the second guide surface 214, and then fall in the area close to the wall 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 tangled is reduced.

[0299] 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.

[0300] 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.

[0301] 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.

[0302] 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.

[0303] 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.

[0304] 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 of the water stirring rib 220 extends from bottom to top, and the angle between the extension direction and the vertical direction gradually decreases, so that the peripheral edge of the water stirring member 200 forms a curve that bends toward the barrel wall of the washing tub 100. The upper end of the peripheral edge of the water stirring rib 220 coincides with the outer periphery of the water stirring plate 230.

[0305] 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.

[0306] It can be understood that the clothes moving along the bottom of the barrel toward the central area can also be lifted along the outer edge of the water-stirring ribs 220 after contacting the water-stirring ribs 220. After moving to the maximum radius of the water-stirring component 200, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom of the barrel along the wall of the washing barrel 100.

[0307] In the preferred solution of this embodiment, the water stirring member 200 is installed in the washing tub 100, and there is a certain gap between the lower end of the water stirring rib 220 and the bottom of the washing tub 100 to avoid a cleaning dead angle between the water stirring rib 220 and the bottom of the tub. Specifically, the lower end of the support column 210 has a connecting portion 215 rotatably inserted into the mounting groove 100-1 on the bottom of the tub, and the lower end of the water stirring rib 220 is at least flush with the upper end of the connecting portion 215, preferably higher than the upper end of the connecting portion 215. The stirring shaft used to drive the water stirring member 200 to rotate is inserted into the connecting portion 215 from the lower end and fixed.

[0308] More preferably, 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.

[0309] 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.

[0310] It is understandable that the connection part at the lower end of the support column can also be completely arranged inside the washing bucket, and the stirring shaft passes through the mounting groove 100-1 on the bottom of the washing bucket and is inserted into the connection part. By setting a certain interval between the lower end surface of the connection part and the bottom of the washing bucket, or setting the difference between the outer diameter and the inner diameter of the connection part to be small enough, the outer surface of the connection part (including the outer side wall and the lower end surface that may exist) and the area of ​​the bottom of the washing bucket located at the periphery of the mounting groove 100-1 can contact the clothes, and the purpose of preventing the existence of cleaning dead corners can also be achieved.

[0311] As a specific implementation, the thickness of the water-stirring rib 220 in the circumferential direction gradually decreases radially outward, and along the axial direction, the thickness of the middle area of ​​the water-stirring rib 220 is greater than the thickness at the upper and lower ends.

[0312] In this embodiment, the distance between the side of the water stirring member 200 and the wall of the washing tub 100 changes, which is formed by the change in the cross-sectional size of the support column 210 itself. Similarly, a structure can be formed in which the maximum radius is at a certain distance from the bottom of the washing tub 100, ensuring that the clothes can be washed below the maximum radius of the water stirring member 200. At the same time, the side wall of the support column 210 forms a first guide surface 213 and a second guide surface 214 for guiding the movement of the clothes during washing, which can effectively drive the clothes to move and turn along a circular path below the maximum radius of the water stirring member 200, so as to achieve a better washing effect and prevent the clothes from being entangled.
