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] The 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. The two are caused to rotate relative to each other, thereby driving the washing water and clothes in the inner barrel to move, and washing 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.

[0003] To solve the above problem, the manufacturer has developed a water-stirring component, which eliminates the bottom disc-shaped stirring part, so that the surface of the water-stirring component below its maximum radius and the inner surface of the barrel bottom at the periphery of the water-stirring component can contact the laundry in the barrel, and the friction between the clothes and the two is used to prevent lint or other dirt from adhering to the surfaces of the two.

[0004] However, when the water stirring member is used in a non-hole drum washing machine, the drain port on the washing drum will be directly exposed to the washing surface at the bottom of the drum. When draining, the drain valve will open the drain port, and the clothes in the inner drum will easily enter the drain port, causing the drain valve to be unable to be completely closed, thereby causing water leakage. At the same time, debris such as lint will enter the drain port with the washing water, which will easily cause the drain port, drainage pipeline and floor drain in the user's home to be blocked.

[0005] Therefore, designing a washing tub assembly that can prevent debris such as clothes and thread scraps in the tub from entering the drain port during drainage has become a technical problem that needs to be solved urgently by those skilled in the art.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0063] 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

[0064] 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.

[0065] 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.

[0066] 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.

[0067] like Figures 1 to 14 As shown, in the embodiment of the utility model, a washing device is introduced, and the washing device at least includes a washing tub 100, a water stirring member 200 and a driving device, wherein the washing tub 100 is used to accommodate the laundry, and the water stirring member 200 is rotatably arranged inside 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 laundry in the washing tub 100.

[0068] In this embodiment, the washing tub 100 is a tub without holes. When washing, the washing tub 100 independently holds washing water. Specifically, the washing device of this embodiment includes the washing tub 100 and a water collecting device. The bottom of the washing tub 100 is provided with a drain port 100-32. During the washing process, there is no water between the washing tub 100 and the water collecting device. During the drainage process and the dehydration process, the water in the washing tub 100 enters the water collecting device and is discharged therefrom. In this embodiment, the water collecting device can be an outer tub or a water collecting device only provided at the bottom of the washing tub 100. In this way, the washing water in the washing tub 100 is discharged after being discharged to the water collecting device. Therefore, the water collecting device has the function of temporarily storing water. The height of the water collecting device is less than the height of the washing tub 100.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] However, when the lint and dirt shed from the clothes 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. Over a long period of time, the gap between the water stirring member 200 and the washing tub 100 will cause dirt to be hidden, bacteria to breed, and cause the problem of secondary pollution of the clothes.

[0073] Embodiment 1

[0074] like Figures 1 to 3 As shown, in an embodiment of the utility model, a washing tub assembly is introduced, the washing tub assembly comprising a washing tub 100 and a water stirring member 200 installed on the bottom of the washing tub 100, and the washing tub assembly is applied to a washing device.

[0075] In this embodiment, the washing tub 100 is a tub without holes, which independently holds washing water when washing clothes.

[0076] In the present embodiment, a washing device is provided 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.

[0077] In this embodiment, the water stirring member 200 extends upward from the bottom of the washing tub 100 and is rotatably disposed in the washing tub 100. The middle or top of the water stirring member 200 has a point with a maximum radius. The point with a maximum radius of the water stirring member 200 faces the bottom of the tub, and the space between the two is used for washing clothes.

[0078] Specifically, the washing device described in this embodiment includes a washing tub 100, a water stirring member 200 and a driving device. The water stirring member 200 is rotatably arranged inside 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 bottom of the washing tub 100, and the certain distance enables the clothes to be washed below the position where the maximum radius Rmax of the water stirring member 200 is located.

[0079] The driving device is transmission-connected to the washing tub 100 and the water-stirring member 200 respectively, and drives the washing tub 100 and the water-stirring member 200 to rotate simultaneously or alternately during washing, thereby driving the clothes in the tub to move for washing.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] In a further solution of this embodiment, the water stirring member 200 at the maximum radius Rmax is also at a certain distance from the barrel mouth of the washing barrel 100 in the height direction, so that the washing water level can be higher than the water stirring member 200 at the maximum radius Rmax, so that the clothes can be washed above the position of the water stirring member 200 at the maximum radius Rmax.

[0092] In the above scheme, the washing tub 100 can accommodate clothes for washing above and below the water stirring member 200 at the maximum radius Rmax. In this way, the outer surface of the water stirring member 200 can basically contact the clothes to be washed and generate friction with the clothes. The washing effect can be enhanced by increasing the surface area in contact with the clothes.

[0093] In this embodiment, the water stirring component 200 includes a support column 210, which extends along the axial direction of the washing barrel 100 and is coaxially arranged between the washing barrel 100, and a water stirring rib 220 is arranged on the circumferential side of the support column 210 and extends along the axial direction of the support column 210. The lower end of the support column 210 is rotatably matched with the bottom of the washing barrel 100.

[0094] A mounting hole is provided at the center of the bottom of the washing tub 100, and the stirring shaft 300 for driving the water stirring member 200 to rotate is rotatably inserted into the mounting hole. The lower end of the support column 210 is sleeved on the upper end of the stirring shaft 300 and is connected to the stirring shaft 300 through a spline to achieve circumferential positioning; the support column 210 and the stirring shaft 300 are axially positioned by screws or a clamping structure.

[0095] The water stirring member 200 may be disposed as a whole above the inner surface of the bottom of the washing tub 100 , or the lower end of the support column 210 of the water stirring member 200 may be at least partially inserted into the inner surface of the bottom of the washing tub 100 .

[0096] Preferably, the area of ​​the barrel bottom extending outward from the lower end of the support column 210 to the barrel wall is the washing surface 100-31, that is, when washing clothes, the area of ​​the barrel bottom extending outward from the lower end of the support column 210 to the barrel wall can contact the clothes in the barrel, that is, the clothes in the washing barrel 100 can reach the outer periphery of the lower end of the support column 210.

[0097] In this embodiment, by setting a water stirring member 200 that rotates with the bottom of the washing tub 100 through the support column 210, the bottom disc-shaped stirring portion is eliminated, and the area of ​​the bottom of the tub extending outward from the lower end of the support column 210 to the tub wall is set as the washing surface 100-31, so that the clothes can come into contact and friction with the area of ​​the bottom of the tub extending outward from the lower end of the support column 210 to the tub wall, thereby avoiding the accumulation of dirt.

[0098] Preferably, in some possible embodiments, the water stirring member 200 is extended upward from the bottom of the washing tub 100, and the lower end of the water stirring member 200 is sleeved on the upper end of the stirring shaft 300 and is not lower than the bottom surface of the outer periphery of the installation through hole; the lower end of the water stirring member 200 is flush or substantially flush with the side wall of the stirring shaft 300 in the radial direction. The area of ​​the bottom of the washing tub 100 extending outward from the installation through hole to the wall of the washing tub 100 is the washing surface 100-31.

[0099] With the structure that the lower end of the water-stirring member 200 has almost no lower end surface, the bottom of the washing tub 100 is completely exposed to the washing water during washing, and the clothes can come into contact with various parts of the bottom of the tub, especially the area around the installation through hole, avoiding the existence of cleaning dead corners at the bottom of the tub that are easy to hide dirt.

[0100] In this embodiment, the horizontal plane where the mounting through hole is located is flush with the washing surface 100-31; or, the washing surface 100-31 has a protruding surface on the periphery of the mounting through hole.

[0101] In other possible embodiments, a mounting groove 100-1 is provided on the upper surface of the bottom of the washing bucket 100, the lower end of the support column 210 is inserted into the mounting groove 100-1, the outer periphery of the lower end of the support column 210 is rotatably matched with the groove wall of the mounting groove 100-1, and the upper surface of the bottom of the outer periphery of the mounting groove 100-1 is the washing surface 100-31.

[0102] Preferably, a water seal structure 500 is provided between the outer periphery of the lower end of the support column 210 and the groove wall of the installation groove 100-1, and the upper end surface of the water seal structure 500 and the inner surface of the barrel bottom of the outer periphery of the water seal structure 500 constitute the washing surface 100-31.

[0103] In a specific solution of this embodiment, the washing surface 100 - 31 occupies 90% or more of the total area of ​​the bottom of the washing tub 100 , and preferably 95% or more of the total area of ​​the bottom of the washing tub 100 .

[0104] In this embodiment, a drain port 100 - 32 and a drain valve 600 for keeping the drain port 100 - 32 normally closed are provided on the bottom of the barrel on the outer periphery of the water stirring member 200 .

[0105] Specifically, in the present embodiment, a drain outlet 100-32 is provided on the area of ​​the barrel bottom extending outward from the lower end of the water stirring member 200 to the barrel wall, that is, the drain outlet 100-32 of the washing barrel 100 is provided on the washing surface 100-31 of the barrel bottom, and the bottom disc-shaped stirring portion is eliminated, so that the water stirring member 200 can be prevented from hindering the washing water from flowing to the drain outlet 100-32 on the washing surface 100-31, thereby improving the drainage speed.

[0106] A drain valve is provided at the drain outlet, and the washing tub 100 is self-sealed through the drain valve 600, so that when the washing equipment is working, no water will accumulate between the washing tub 100 and the water collecting device to prevent contamination. It is also an application of water-saving technology for users. In addition, after the washing tub 100 is self-sealed through the drain valve 600, the washing tub 100 and the water stirring member 200 can achieve relative rotation to realize the function of dual-power washing clothes.

[0107] In this embodiment, a driving component corresponding to the drain valve 600 is provided at the bottom of the water collecting device, and the driving component is used to drive the drain valve 600 to open. When the washing device is washing, the working end of the driving component shrinks downward and separates from the valve plug 600-1 of the drain valve 600 to avoid interference with the rotation of the washing tub 100; when the washing device is draining, the washing tub 100 rotates to the position where the drain valve 600 corresponds to the working end of the driving component, and the working end of the driving component extends upward to push the valve plug 600-1 of the drain valve 600 to move upward, thereby opening the drain port 100-32.

[0108] Preferably, in this embodiment, the washing device further comprises a locking component, which can lock and position the washing tub 100. After the locking component locks the washing tub 100, it is easier for the driving component to drive the drain valve 600 to open, thereby ensuring normal drainage.

[0109] In this embodiment, the specific structure of the locking component of the washing device can adopt the structure of the locking component in the existing dual-power washing device.

[0110] Preferably, Figure 1 and Figure 2 As shown, in this embodiment, a valve cover 800 is provided on the inner surface of the barrel bottom and covers the drain outlet 100-32, and a hollow hole 803 for washing water to pass through is provided on the wall of the valve cover 800.

[0111] In this embodiment, by arranging the valve cover 800 on the inner surface of the barrel bottom, the washing water is discharged through the hollow hole 803 on the valve cover 800, which can prevent the clothes and debris such as thread scraps in the washing barrel 100 from entering the drain port 100-32, thereby preventing the clothes in the washing barrel 100 from blocking the drain valve 600 from closing the drain port 100-32, improving the working stability of the drain valve 600, and at the same time, filtering the debris such as thread scraps in the washing water, preventing the debris such as thread scraps from entering the drain port 100-32 and causing the drain port 100-32, the drainage pipeline and the floor drain in the user's home to be blocked. In addition, by arranging the drain port 100-32 on the area where the lower end of the water stirring member 200 extends outward to the barrel wall, the valve cover 800 can be brought into contact with the clothes in the barrel, and the friction of the clothes can be used to prevent the debris such as thread scraps from clogging the hollow hole 803 on the valve cover 800, thereby ensuring the drainage efficiency.

[0112] At the same time, it can also enrich the structure of the washing surface 100-31 at the bottom of the barrel and improve the washing effect on clothes.

[0113] like Figure 3As shown, in this embodiment, the valve cover 800 includes a top wall 801 and a surrounding wall 802, and the top wall 801 and the surrounding wall 802 are integrally formed to form the valve cover 800. The projection of the valve cover 800 on the barrel bottom covers the drain port 100-32, the lower end of the surrounding wall 802 is arranged around the drain port 100-32, and the lower end of the surrounding wall 802 abuts against the inner surface of the barrel bottom at the periphery of the drain port 100-32, so that the drain port 100-32 is covered in the valve cover 800, and the top wall 801 and / or the surrounding wall 802 of the valve cover 800 are provided with a hollow hole 803 for discharging washing water.

[0114] In this embodiment, the top wall 801 of the valve cover 800 is arranged above the drain outlet 100-32, and the surrounding wall 802 of the valve cover 800 extends downward from the edge of the top wall 801, and the lower end of the surrounding wall 802 abuts against the inner surface of the barrel bottom around the drain outlet 100-32; the hollow hole 803 is arranged on the top wall 801 and / or the surrounding wall 802.

[0115] In this embodiment, the valve cover 800 may be of any shape as long as the drain port 100 - 32 can be covered within the valve cover 800 .

[0116] In some possible embodiments, the projection coverage of the top wall 801 of the valve cover 800 on the barrel bottom is smaller than the range of the drain outlet 100-32, and the surrounding wall 802 extends obliquely from top to bottom toward the periphery of the drain outlet 100-32, and the lower end of the surrounding wall 802 is arranged around the drain outlet 100-32.

[0117] In other possible embodiments, the coverage of the projection of the top wall 801 of the valve cover 800 on the bottom of the barrel is greater than or equal to the range of the drain outlet 100-32, and the surrounding wall 802 extends vertically from top to bottom, or the surrounding wall 802 extends obliquely from top to bottom toward the periphery of the projection of the top wall 801 on the bottom of the barrel.

[0118] In this embodiment, the top wall 801 is arranged opposite to the drain outlet 100 - 32 , and the top wall 801 can be arranged in a horizontal form, an inclined form, or a curved form.

[0119] Preferably, in this embodiment, the top wall 801 of the valve cover 800 is set to a regular plane, an arc-shaped curved surface, or a wavy curved surface to avoid the presence of four corners that are easy to hide dirt.

[0120] Preferably, in this embodiment, the top wall 801 is arranged above the drain outlet 100-32, facing the drain outlet 100-32, the projection of the top wall 801 of the valve cover 800 on the bottom of the barrel covers the drain outlet 100-32, and the surrounding wall 802 extends vertically downward from the edge of the top wall 801.

[0121] Preferably, in this embodiment, a circular chamfer is provided at the connection between the top wall 801 and the side wall of the valve cover 800. Thus, during the washing process, it is easy for clothes to pass through the valve cover 800, and the valve cover 800 can be prevented from damaging the clothes. At the same time, the dead corners on the valve cover 800 that are difficult to clean can be further reduced.

[0122] Preferably, in this embodiment, the valve cover 800 is configured to be in the shape of a long strip, and the length direction of the valve cover 800 is perpendicular to the vertical line between the rotation center of the water stirring member 200 and the center of the drain port 100-32. Thus, the resistance of the valve cover 800 to the clothes can be reduced, and the smoothness of the clothes moving in the washing tub 100 can be improved.

[0123] The top wall 801 of the valve cover 800 is configured to be curved downward. Specifically, the top wall 801 of the valve cover 800 is curved downward in a direction away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32. Preferably, the end of the top wall 801 of the valve cover 800 away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32 is substantially in contact with the inner surface of the bottom of the barrel. In this embodiment, the clothes in the barrel mainly move along the circumferential direction of the washing barrel 100 under the stirring of the water stirring member 200. Through the above configuration, the valve cover 800 can further reduce the resistance to the rotation of the clothes, so that the clothes can pass smoothly through the area where the valve cover 800 is located.

[0124] In this embodiment, the end of the top wall 801 of the valve cover 800, which is away from the vertical line between the rotation center of the water-stirring member 200 and the center of the drain outlet 100-32, is basically in contact with the inner surface of the barrel bottom. Specifically, the end of the upper end surface of the valve cover 800 and the inner surface of the barrel bottom can be smoothly transitioned, or the end of the upper end surface of the valve cover 800 is slightly higher than the inner surface of the barrel bottom, thereby further reducing the resistance of the valve cover 800 to the circumferential movement of the clothes in the washing barrel 100.

[0125] Preferably, in this embodiment, the upper end surfaces at both ends of the valve cover 800 smoothly transition to the inner surface of the barrel bottom through a rounded corner or a downwardly inclined slope that bends downward in a direction away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32.

[0126] Further preferably, the width of the valve cover 800 gradually decreases along a direction away from a vertical line between a rotation center of the water agitation member 200 and a center of the drain port 100 - 32 .

[0127] In this embodiment, through the above-mentioned arrangement, when the clothes pass through the area on the inner surface of the barrel bottom where the valve cover 800 is located, they can move smoothly along the upper end surface of the valve cover 800, the side close to the water-stirring component 200, and the side away from the water-stirring component 200. On the one hand, it can facilitate the clothes to pass through this area. On the other hand, the contact and friction between the clothes and the valve cover 800 can be used to prevent dirt from adhering to the valve cover 800, thereby avoiding the formation of dead corners that are difficult to clean on the washing surface 100-31 of the barrel bottom due to the arrangement of the valve cover 800.

[0128] Still further preferably, in this embodiment, the valve cover 800 is bilaterally symmetrical with respect to a vertical line between a rotation center of the water stirring member 200 and a center of the drain outlet 100 - 32 .

[0129] In this embodiment, the end of the valve cover 800 close to the water stirring member 200 and the end away from the water stirring member 200 are respectively spaced apart from the water stirring member 200 and the barrel wall, and the two ends of the valve cover 800 away from the vertical line between the rotation center of the water stirring member 200 and the center of the drain outlet 100-32 are spaced apart from the barrel wall, so that clothes can pass smoothly between the water stirring member 200 and the valve cover 800, and between the valve cover 800 and the barrel wall, avoiding the situation where clothes are stuck.

[0130] In this embodiment, the drain port 100-32 can be of any shape. Preferably, the drain port 100-32 is circular or elliptical, and the center of the drain port 100-32 is the center of the circular drain port 100-32, or the midpoint of the connecting line of the two foci of the elliptical drain port 100-32. The vertical line between the rotation center of the water stirring member 200 and the center of the drain port 100-32 is perpendicular to the rotation center of the water stirring member 200.

[0131] Preferably, in this embodiment, the water stirring member 200 is coaxially arranged with the washing tub 100 , and a vertical line between a rotation center of the water stirring member 200 and a center of the drain port 100 - 32 extends along a radial direction of the washing tub 100 .

[0132] In this embodiment, the hollow holes 803 on the wall of the valve cover 800 include a first hollow hole 8031 ​​arranged on the top wall 801 of the valve cover 800, and a second hollow hole 8032 arranged on the surrounding wall 802 of the valve cover 800, and a plurality of the first hollow holes 8031 ​​and the second hollow holes 8032 are respectively arranged.

[0133] In this embodiment, the first hollow hole 8031 ​​and the second hollow hole 8032 are both small holes, which can prevent the passage of debris such as lint in the washing water to a certain extent. The first hollow hole 8031 ​​and the second hollow hole 8032 can be of any shape.

[0134] Preferably, in some specific embodiments of the present invention, the first hollow hole 8031 ​​and the second hollow hole 8032 may be small round holes, strip holes, or multiple coaxially arranged annular holes.

[0135] In this embodiment, the first hollow hole 8031 ​​is a small round hole, and the second hollow hole 8032 is configured as a grille hole.

[0136] Specifically, in this embodiment, the second hollow hole 8032 is arranged at the lower end of the surrounding wall 802, and is U-shaped with the opening facing downward, and is formed by being recessed upward from the lower end surface of the surrounding wall 802. There are multiple second hollow holes 8032 arranged along the length direction of the surrounding wall 802.

[0137] When the valve cover 800 is mounted on the bottom of the tub, the lower end of the surrounding wall 802 of the valve cover 800 fits with the inner surface of the bottom of the tub, and the inner surface of the bottom of the tub closes the opening of the U-shaped second hollow hole 8032 to form a grille hole. Therefore, during the washing process, the washing water can flow between the cavity of the valve cover 800 and the washing tub 100, thereby improving the flushing effect of the inside of the valve cover 800 and ensuring the drainage effect, so that the washing water in the washing tub 100 can be completely discharged from the second hollow hole 8032.

[0138] In some possible embodiments, the hollow holes may be distributed throughout the entire valve cover. Specifically, the first hollow holes cover the entire top wall of the valve cover, and the second hollow holes cover the entire surrounding wall of the valve cover. The hollow holes may also be concentrated in a certain area of ​​the top wall and / or the surrounding wall.

[0139] Preferably, in this embodiment, the second hollow holes 8032 are concentratedly arranged on a side of the surrounding wall 802 of the valve cover 800 close to the water stirring member 200 and a side away from the water stirring member 200, which can improve drainage efficiency.

[0140] Further preferably, in this embodiment, the first hollow holes 8031 ​​are concentrated and arranged in the middle of the top wall 801 of the valve cover 800 .

[0141] Still further preferably, the first hollow holes 8031 ​​are concentratedly arranged within a range covered by a vertical projection of the drain outlet 100 - 32 on the top wall 801 of the valve cover 800 .

[0142] In this embodiment, the top wall 801 of the valve cover 800 is configured to be bent downward, which can further increase the layout area for setting the first hollow holes 8031, which is beneficial to increase the number of the first hollow holes 8031.

[0143] In this embodiment, the valve cover 800 is detachably mounted on the bottom of the barrel.

[0144] In a specific embodiment of the present invention, the valve cover 800 is mounted on the bottom of the barrel by screws. Specifically, the valve cover 800 is fixed by at least two screws. A connecting groove 804 extending vertically downward is respectively provided on the top wall 801 of the valve cover 800 and close to both ends of the valve cover 800. A through hole for the rod of the screw to pass through is provided on the bottom of the connecting groove 804. Preferably, an internal thread matching the external thread on the rod of the screw is provided on the inner wall of the through hole. A threaded hole matching the screw is provided on the bottom of the barrel. The rod of the screw passes through the through hole on the bottom of the connecting groove 804 and is tightened in the threaded hole on the bottom of the barrel. The head of the screw is embedded in the connecting groove 804 and abuts against the bottom of the connecting groove 804 to achieve the installation of the valve cover 800. At the same time, the connecting groove 804 can hide the head of the screw to prevent the head of the screw from damaging the clothes.

[0145] In this embodiment, the drain valve 600 includes a valve plug 600 - 1 and an elastic component for driving the drain valve 600 to close.

[0146] In this embodiment, the valve plug 600-1 is arranged at the drain outlet 100-32, and the sealing part of the valve plug 600-1 is arranged in the cavity of the valve cover 800, moving from top to bottom to block the drain outlet 100-32; the elastic component is arranged between the valve plug 600-1 and the bottom of the barrel to drive the valve plug 600-1 to move downward.

[0147] Specifically, the shape of the sealing part of the valve plug 600-1 is adapted to the shape of the drain outlet 100-32, and the outer peripheral wall of the sealing part is inclined from top to bottom toward the center of the sealing part. The valve plug 600-1 is inserted into the drain outlet 100-32 from top to bottom, and the sealing part is at least partially inserted into the drain outlet 100-32. The outer peripheral wall of the sealing part is elastically abutted against the drain outlet 100-32 to close the drain outlet 100-32.

[0148] Preferably, in this embodiment, the inner diameter of the upper end of the drain port 100-32 gradually decreases from top to bottom, and the sealing portion of the valve plug 600-1 is embedded in the upper end of the drain port 100-32 from top to bottom to seal the drain port 100-32. Preferably, the upper end surface of the valve plug 600-1 is substantially flush with the inner surface of the barrel bottom at the periphery of the drain port 100-32.

[0149] In this embodiment, the upper end surface of the valve plug 600-1 is basically flush with the inner surface of the barrel bottom around the drain outlet 100-32. The upper end surface of the valve plug 600-1 can be flush with the inner surface of the barrel bottom around the drain outlet 100-32, or the upper end surface of the valve plug 600-1 can be slightly higher than the inner surface of the barrel bottom around the drain outlet 100-32, or the upper end surface of the valve plug 600-1 can be slightly lower than the inner surface of the barrel bottom around the drain outlet 100-32.

[0150] In this embodiment, when the drain valve 600 is opened, the sealing portion of the valve plug 600-1 moves into the cavity of the valve cover 800, and the washing water enters the cavity of the valve cover 800 from the hollow hole 803 on the valve cover 800, and then flows out from the drain port 100-32.

[0151] In a specific embodiment of the present invention, the drain valve 600 also includes a supporting component, which is fixedly installed at the bottom of the washing tub 100 and extends to the bottom of the drain outlet. The valve plug 600-1 of the drain valve 600 can be relatively slidably installed on the supporting component.

[0152] The supporting component includes a fixing part and a sleeve part. The fixing part is fixedly installed at the bottom of the washing bucket 100 and extends to the bottom of the drain outlet. The sleeve part is fixedly connected to the sleeve part. The sleeve part has a hollow slide. The valve plug 600-1 of the drain valve 600 includes a sealing part and a sliding rod. The sliding rod is slidably arranged in the hollow slide of the sleeve part to realize the sealing part to block / conduct the drain outlet.

[0153] The sealing part further comprises a sealing gasket, which is an annular structure and is arranged on the outer peripheral wall of the sealing part. The sealing part abuts against the inner wall of the drain outlet through the sealing gasket.

[0154] In order to maintain the self-sealing of the sealing part and the reset seal after drainage, the drain valve 600 includes an elastic component, one end of which is abutted against the supporting component and the other end is abutted against the valve plug 600-1. The elastic component is deformed when the sealing part slides to a state separated from the drain port, thereby realizing the elastic reset seal of the sealing part. The initial state of the elastic component is in a compressed state to keep the sealing part sealing the upper end of the drain port.

[0155] As an implementation of this embodiment, the elastic component is a compression spring, which is sleeved in the hollow slideway of the sleeve portion. One end of the compression spring stops at the sleeve portion, and the other end stops at the bottom of the valve plug 600-1.

[0156] Furthermore, a screw is installed at the end of the sliding rod, and the upper end of the sleeve portion has a limiting step extending a certain distance toward the inside of the hollow slideway. The compression spring is sleeved on the center rod, one end of which stops on the screw and the other end stops on the limiting step.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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 .

[0161] 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.

[0162] 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 .

[0163] 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] By arranging the second hollow holes 8032 on the side of the surrounding wall 802 of the valve cover 800 close to the water-stirring component 200 and the side away from the water-stirring component 200, the washing water can be stirred by the water-stirring component 200 and rushed into the cavity of the valve cover 800 from the second hollow holes 8032 on the side of the valve cover 800 away from the water-stirring component 200, and after flushing the cavity in the valve cover 800, it flows out from the second hollow holes 8032 on the side of the valve cover 800 close to the water-stirring component 200, thereby improving the flushing effect on the interior of the valve cover 800. At the same time, during the washing process, the washing water in the valve cover 800 can always be in a state of circulation with the washing water outside the cavity, thereby reducing the force applied to the valve cover 800 and improving the service life and installation stability of the valve cover 800.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] In an embodiment of the present invention, a control method for a washing device is also provided, wherein the washing device is equipped with the above-mentioned washing bucket assembly. The control method for the washing device comprises:

[0173] During the drainage process of the washing tub 100, the water stirring member 200 rotates to speed up the drainage.

[0174] Specifically, in the present embodiment, by arranging the water stirring member 200 to rotate during the drainage process of the washing tub 100, on the one hand, the washing water can flow toward the periphery and smoothly enter the drainage port 100-32; on the other hand, during the rotation of the water stirring member 200, the clothes in the washing tub 100 move upward and toward the periphery along the side walls of the first extension section 211 and the side walls of the second extension section 212, thereby preventing the clothes from clogging the through holes on the valve cover and increasing the drainage speed.

[0175] Preferably, in this embodiment, the washing device detects the drainage speed during the drainage process, and when the drainage speed slows down, the water stirring member 200 is driven to rotate to stir the clothes. Alternatively, when the washing device detects that the drainage is overtime, the water stirring member 200 is driven to rotate to stir the clothes. Alternatively, during the drainage process, the washing device drives the water stirring member 200 to rotate intermittently or continuously to prevent the clothes from blocking or blocking the drainage port 100-32.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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 .

[0196] Embodiment 2

[0197] like Figures 4 to 7 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.

[0198] In this embodiment, the washing tub 100 is a tub without holes.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] 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 peripheral 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.

[0203] 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.

[0206] The mounting groove 100-1 is arranged on the inner surface of the bottom of the washing bucket 100 and is coaxially arranged with the washing bucket 100. The mounting groove 100-1 corresponds to the lower end of the support column 210. The lower end of the support column 210 is at least partially inserted into the mounting groove 100-1 to form a rotating pair with the groove wall of the mounting groove 100-1. The water seal structure 500 is arranged between the groove wall of the mounting groove 100-1 and the circumferential surface of the lower end of the support column 210.

[0207] In this embodiment, the support column 210 extends along the axial direction of the washing tub 100, and the circumferential side of the support column 210 is arranged opposite to the barrel wall of the washing tub 100. 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.

Preferably, the outer diameter of the water seal structure 500 is greater than or equal to the inner diameter of the mounting groove, and the inner edge of the water seal structure 500 is elastically abutted against the lower end circumference of the support column 210.

[0251] Embodiment 3

[0254] 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.

[0298] Embodiment 4

[0299] like Fig.12 and Fig.13 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.

[0300] 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.

[0301] 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.

[0302] 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.

[0303] 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.

[0304] 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.

[0305] 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.

[0306] 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.

[0307] 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.

[0308] 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.

[0309] 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 .

[0310] In the preferred embodiment of this embodiment, Fig.13 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.

[0311] 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.

[0312] 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.

[0313] 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.

[0314] 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.

[0315] 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.

[0316] 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.

[0317] 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.

[0318] 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.

[0319] 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.

[0320] 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.

[0321] 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.

[0322] 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.

[0323] 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.

[0324] 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.

[0325] 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.

[0326] 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.
