Description

[0001] This application is a divisional application of Chinese Patent Application No. 202323447812.4.

[0003] Original application number: 202323447812.4

[0004] Original utility model title: A washing tub assembly and washing equipment for a washing machine Technical Field

[0005] This utility model belongs to the field of washing equipment technology, specifically, it relates to a washing device. Background Technology

[0006] Washing machines, as a convenient garment cleaning device, have become widely used in people's lives. Currently available washing machines are divided into front-loading and top-loading types, with top-loading washing machines being more popular due to their superior cleaning performance.

[0007] Top-loading washing machines typically consist of an inner tub and an pulsator, with the pulsator located at the bottom of the inner tub. During operation, the rotation of the pulsator rotates the washing water within the inner tub, washing the clothes. Existing pulsators are usually flat and round. During washing, dirt, lint, and other impurities from clothes easily accumulate in the gap between the bottom of the pulsator and the inner tub, which cannot be effectively cleaned by simply rinsing. Furthermore, dirt and lint in a damp environment can easily breed bacteria, leading to a poor user experience. Thorough cleaning requires removing the pulsator to scrub the dirt in the gap, a cumbersome process that further degrades the user experience.

[0008] Existing technologies also include agitator-type washing machines, which use an agitator of a certain size along the axial direction of the inner tub to replace the pulsator in a top-loading washing machine. However, as... Figure 1 As shown, the agitator 1 in existing agitator washing machines is often in an inverted T-shape, consisting of an axial agitator 2 and a radial agitator 3. The radial agitator 3 is located at the bottom of the washing tub 4 and has a larger radial dimension. Clothes Y can only be washed in the area above the radial agitator 3 inside the tub, which still cannot solve the problem of dirt and grime accumulating in the gap between the agitator 1 and the bottom of the tub, making it difficult to clean. Some other agitator washing machines directly install the columnar agitator rod on the pulsator at the bottom of the tub, but dirt and bacteria can still easily accumulate between the pulsator and the bottom of the tub.

[0009] In view of the above, this utility model is hereby proposed. Utility Model Content

DETAILED DESCRIPTION

[0066] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings of the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0067] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0068] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0069] As shown in the drawings, Figures 2 to 16 The embodiments of the present application provide a washing tub assembly of a washing device, and a washing device with the washing tub assembly. The washing device can be a washing machine, a washing and drying integrated machine, a care machine, or other washing devices with clothes washing function.

[0070] Specifically, the washing tub assembly comprises a washing tub 100 and a water stirring member 200 rotatably arranged inside the washing tub 100. The washing apparatus further comprises a driving device, such as a driving motor, which is in driving connection with the washing tub 100 and the water stirring member 200 respectively.

[0071] More specifically, the output shaft of the driving device is in driving connection with the stirring shaft 300 and the dewatering shaft 110 respectively. The stirring shaft 300 is connected with and fixed relative to the water stirring member 200 for driving the water stirring member 200 to rotate. The dewatering shaft 110 is fixed with the bottom of the washing tub 100 for driving the washing tub 100 to rotate.

[0072] 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 reversely, so as to stir the clothes C and washing water in the washing tub by the relative rotation trend between the water stirring member 200 and the washing tub 100, and to clean the clothes C. During the dewatering process, the driving device drives the water stirring member 200 and the washing tub 100 to rotate synchronously at high speed, so as to spin dry the clothes C in the washing tub by centrifugal force.

[0073] However, if there is a relatively narrow gap structure between the water stirring member 200 and the washing tub 100, the lint and dirt falling off the clothes C during the washing process can easily hide in the gap structure and are difficult to be brought out by the water flow impact force during the washing process, and thus need to be cleaned manually by the user by disassembling the water stirring member 200. If the user does not clean 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 can easily breed bacteria and cause secondary pollution of the clothes C.

[0074] Embodiment One

[0075] As shown in Figure 2 and Figure 3 The present embodiment provides a washing tub assembly of a washing apparatus and a washing apparatus with the same, for solving the problem that the water stirring member 200 and the washing tub 100 have a dead angle for hiding dirt and are difficult to clean.

[0076] Specifically, the washing tub assembly comprises a washing tub 100 and a water stirring member 200 rotatably arranged inside the washing tub 100. The water stirring member 200 extends upwards from the bottom of the washing tub 100 and has a maximum diameter at a certain distance from the bottom, and the certain distance allows the clothes C to be washed below the position where the water stirring member 200 has the maximum diameter Dmax.

[0077] The water stirring member 200 described in the embodiment has the matching structure described above with the washing tub 100, and compared with a traditional pulsator washing machine or a stirring type washing machine with a radial stirrer, has a washing space below the maximum diameter position Dmax of the water stirring member 200, the washing space is formed by the surface of the water stirring member 200 below the maximum diameter position Dmax, the tub wall of the washing tub 100 and the bottom of the washing tub 100, the clothes C can be washed in the washing space, so that the surface of the water stirring member 200 below the maximum diameter position Dmax and the bottom of the washing tub 100 can be in contact with the clothes C in the tub. During the washing process, the friction between the clothes C and the surface of the water stirring member 200 can prevent lint or other dirt from adhering to the surface of the water stirring member 200, effectively avoiding the problem that the water stirring member 200 and the bottom are easy to hide dirt and difficult to clean, and improving the user experience.

[0078] It should be noted that in the embodiment of the utility model, the diameter of the water stirring member 200 refers to the diameter of the cross section of the water stirring member 200 along the direction perpendicular to the rotation axis (see Figure 4 ) of the water stirring member 200, and the diameter is twice the distance between the farthest point on the cross section from the rotation center and the rotation center.

[0079] Specifically, if the cross section of the water stirring member 200 is a circle as shown in the figure, Figure 5 the diameter is the diameter D of the circular cross section. If the cross section of the water stirring member 200 is a non-circular shape as shown in the figure, Figures 6 to 11 the diameter is twice the distance R from the farthest point on the cross section to the rotation center (i.e. the position marked by "X" in the figure).

[0080] As a specific embodiment, in the embodiment, the distance h between the maximum diameter position Dmax of the water stirring member 200 and the bottom is more than 10 cm, so as to ensure that the clothes C can be washed below the maximum diameter position Dmax.

[0081] In a further scheme of the embodiment, the maximum diameter position Dmax of the water stirring member 200 and the opening of the washing tub 100 also have a certain distance in the height direction, so that the washing water level can be higher than the maximum diameter position Dmax of the water stirring member 200, and the clothes C can be washed above the position of the maximum diameter position Dmax of the water stirring member 200.

[0082] In the above scheme, the clothes C can be accommodated and washed above and below the maximum diameter position Dmax of the water stirring member 200 in the washing tub 100, so that the outer surface of the water stirring member 200 can basically contact the clothes C and generate friction with the clothes C, and the washing effect can be enhanced by increasing the surface area in contact with the clothes C.

[0083] In comparison with the pulsator washing machine, in the present embodiment, when the water level is lower than the height of the maximum diameter Dmax, the laundry C only contacts the side surface of the water stirring member 200, and the laundry C is moved in the tub mainly by the water flow generated by the water stirring member 200, so that the force directly applied by the water stirring member 200 to the laundry C is greatly reduced, and the effect of preventing the laundry from being entangled is achieved. If the water level is higher than the height of the maximum diameter Dmax, although part of the laundry C is washed above the maximum diameter Dmax, since the maximum diameter of the water stirring member 200 in the present embodiment is much smaller than the diameter of the washing tub 100, and is not close to the diameter of the tub as in the pulsator washing machine, the contact area between the water stirring member 200 and the laundry C is greatly smaller than the contact area between the pulsator and the laundry in the pulsator washing machine, so that the possibility of the laundry being entangled is greatly reduced.

[0084] Furthermore, since the contact area between the laundry C and the water stirring member 200 is reduced, the friction between the laundry C and the water stirring member 200 is reduced, which helps to reduce the abrasion of the laundry by the water stirring member 200, and the power consumption of the motor when the driving device drives the water stirring member 200 to rotate is reduced.

[0085] In the present embodiment, the side surface of the water stirring member 200 is arranged such that, as the height of the rotation axis increases, the distance between the side surface of the water stirring member 200 and the tub wall of the washing tub 100 remains constant, or gradually or stepwise changes.

[0086] As a specific embodiment, as shown in Figure 2 the water stirring member 200 has a unique maximum diameter Dmax in the height direction. Further, at least below the maximum diameter Dmax, as the height increases, the distance between the side surface of the water stirring member 200 and the tub wall of the washing tub 100 decreases as the height increases.

[0087] It should be noted that the unique maximum diameter Dmax can refer to that the water stirring member 200 has the maximum diameter Dmax at a specific height position, or can refer to that the water stirring member 200 has the maximum diameter Dmax in a certain continuous height range.

[0088] In a specific scheme, as shown in Figure 2As shown, the maximum diameter Dmax of the water stirring member 200 is close to the top of the water stirring member 200, but is at a distance from the top of the water stirring member 200. Specifically, the upper side surface of the water stirring member 200 at the maximum diameter Dmax is a convex curved surface, and the highest point of the curved surface forms the top of the water stirring member 200.

[0089] In a further aspect of the embodiment, the height of the maximum diameter Dmax of the water stirring member 200 is arranged between the highest water level and the lowest water level of the washing apparatus. In this way, when the washing apparatus is operated at different water levels, the rotation of the water stirring member 200 can generate different water flow patterns to drive the laundry C to move for washing. In particular, as a specific embodiment, below the maximum diameter Dmax of the water stirring member 200, the laundry C can move along the annular path for washing.

[0090] The annular path described above refers to moving towards the center in the bottom region of the washing tub 100, being lifted by the water stirring member 200 to a position close to the maximum diameter Dmax of the water stirring member 200, moving outwardly after falling.

[0091] Referring to Figure 12 and Figure 13 , as a specific embodiment, the annular path of the laundry moving below the maximum diameter Dmax of the water stirring member 200 during washing includes: the laundry moving towards the center along the bottom of the washing tub 100, moving upwards along the side of the water stirring member 200 below the maximum diameter Dmax and then moving outwardly, and moving downwards in the region close to the wall of the washing tub 100.

[0092] In a further aspect of the embodiment, the water stirring member 200 includes a support column 210 arranged coaxially with the washing tub 100, and a water stirring rib 220 protruding from the side wall of the support column 210. The support column 210 is used to drive connect the driving device of the washing apparatus, so that the water stirring member 200 can rotate under the driving of the driving device. The water stirring rib 220, along with the rotation of the water stirring member 200 in the washing tub 100, stirs the laundry C and water flow in the tub. The bottom of the washing tub 100, the side wall of the support column 210 and the wall of the washing tub 100 together form a space capable of accommodating the laundry C during washing, and the laundry C can move along the annular path described above in the space.

[0093] When the washing tub assembly of the embodiment is applied to a washing apparatus, in a specific embodiment, as shown in Figure 12 , when operated at a low water level W1 below the maximum diameter Dmax of the water stirring member 200, the laundry can move along the annular path described above in the water.

[0094] Specifically, during the washing process, the relative rotation between the water stirring member 200 and the washing tub 100 is generated, and the laundry moves along the path shown by the arrow in the figure in the space below the maximum diameter Dmax of the water stirring member 200. That is, the laundry moves to the central area along the bottom of the washing tub 100, is lifted to below the maximum diameter Dmax along the side wall of the support column 210 or the outer peripheral edge of the water stirring rib 220 in the central area, moves outwardly, and then falls to the bottom of the washing tub 100 in the area close to the tub wall, forming a circular motion mode.

[0095] As shown in Figure 13 When the high water level W2 higher than the maximum diameter Dmax of the water stirring member 200 is used, the laundry moves along the circular path in the water in the area below the maximum diameter Dmax of the water stirring member 200, and the laundry moves close to the circumferential direction of the washing tub 100 in the area above the maximum diameter Dmax of the water stirring member 200.

[0096] Specifically, during the washing process, the relative rotation between the water stirring member 200 and the washing tub 100 is generated, and the laundry moves along the path shown by the arrow in the figure in the space below the maximum diameter Dmax of the water stirring member 200. That is, the laundry moves to the central area along the bottom of the washing tub 100, is lifted to below the maximum diameter Dmax along the side wall of the support column 210 or the outer peripheral edge of the water stirring rib 220 in the central area, moves outwardly, and then falls to the bottom of the washing tub 100 in the area close to the tub wall, forming a circular motion mode.

[0097] In the above scheme, when different water levels are used, the water stirring member 200 can drive the laundry in the tub to move in different ways for washing, providing more diversified washing mode selection. Moreover, in the area below the maximum diameter Dmax of the water stirring member 200, since the laundry moves along the circular path, on the one hand, the turning of the laundry can be enhanced, and the washing effect can be enhanced, and on the other hand, the problem that the laundry is easily driven to the center to be gathered and to be entangled in the existing impeller washing machine can be avoided.

[0098] In the embodiment, the protruding direction of the water stirring rib 220 on the side wall of the support column 210 is radially coincident with the washing tub 100 or forms an angle less than 90° with 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 rotating direction, which can effectively stir the water.

[0099] More specifically, a plurality of water stirring ribs 220 are circumferentially spaced apart on the side wall of the support column 210, and are preferably symmetrically arranged with respect to the rotation axis. The laundry C can be washed in the interval between two adjacent water stirring ribs 220, so as to contact the two side surfaces of the water stirring ribs 220 and the region of the side wall of the support column 210 between the two water stirring ribs 220, avoiding the existence of cleaning dead angles on the side wall of the support column 210 which are prone to attach dirt. At the same time, during washing, the laundry C moving towards the central region along the bottom of the washing tub 100 is lifted along the side wall of the support column 210 to below the maximum diameter Dmax of the water stirring member 200, and then falls after moving towards the periphery, forming a circular path.

[0100] The water stirring member 200 having the above structure has a side surface comprising 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 diameter of the water stirring member 200 is twice the distance between the farthest end of the water stirring rib 220 from the rotation axis and the rotation axis.

[0101] In the above structure, the diameter of the water stirring member 200, specifically referring to the cross section of the water stirring member 200 taken along the horizontal direction, in the obtained cross section, the distance between the farthest end of the water stirring rib 220 from the rotation axis and the central axis is twice. When the number of water stirring ribs 220 is even, the length of the line connecting the farthest ends of the two water stirring ribs 220 from the rotation axis is the diameter of the water stirring member 200 at that position. When the number of water stirring ribs 220 is odd, there is no oppositely arranged water stirring rib 220, and the cross section of the water stirring member 240 taken along the horizontal direction does not form an axisymmetric figure, but the diameter of the cross section of the water stirring member 240 is still twice the distance between the farthest end of the water stirring rib 220 from the rotation axis and the central axis.

[0102] As a specific solution of the present embodiment, as shown in Figure 2 At the position below the maximum diameter Dmax of the water stirring member 200, the support column 210 has or substantially maintains the same diameter along the axial direction.

[0103] Here, the support column 210 having the same diameter along the axial direction means that the side wall of the support column 210 is arranged to extend upward along the vertical direction until reaching the position of the maximum diameter Dmax of the water stirring member 200. The support column 210 substantially maintaining the same diameter along the axial direction can mean that the side wall of the support column 210 extends upward along a straight line close to the vertical direction until reaching the position of the maximum diameter Dmax of the water stirring member 200.

[0104] The water stirring ribs 220 protrude from the side wall of the support column 210 and have a certain height in the axial direction of the washing tub 100. The radial dimension of the water stirring ribs 220 increases with the height, so that the distance between the side of the water stirring member 200 and the tub wall of the washing tub 100 decreases with the height.

[0105] Further, the lower end of the water stirring ribs 220 is spaced apart from the bottom of the washing tub 100. Specifically, the bottom of the support column 210 has a mounting portion for connecting the stirring shaft 300, and the outer peripheral edge of the water stirring ribs 220 extends upwardly at a constant or gradually changing angle from the side wall of the support column 210 at a certain distance from the upper end of the mounting portion, and finally extends to the height at which the diameter Dmax of the water stirring member 200 is the largest. There is no structure extending in the radial direction of the washing tub 100 between the lower end of the water stirring ribs 220 and the mounting portion, and the bottom of the washing tub 100 is not covered, so that there is substantially no area on the bottom of the washing tub 100 that cannot contact the laundry.

[0106] In the first specific embodiment, a recess structure with an open upper side is provided on the bottom of the washing tub 100, the mounting through hole provided in the bottom wall of the recess structure is penetrated by the stirring shaft 300, the mounting portion is rotatably inserted into the recess structure, and the lower end of the water stirring ribs 220 is not lower than the upper end of the mounting portion, so that the lower end surface of the water stirring ribs 220 can contact the laundry. At the same time, since there is no structure extending in the radial direction of the washing tub between the lower end of the water stirring ribs 220 and the mounting portion, the area of the bottom of the washing tub 100 outside the periphery of the recess structure can also contact the laundry, preventing the attachment of lint and dirt.

[0107] In the second specific embodiment, the lower end surface of the mounting portion is spaced apart from the bottom of the washing tub, and the stirring shaft 300 is connected to the mounting portion by penetrating the mounting through hole provided in the bottom of the washing tub 100. The spacing allows the lower end surface of the mounting portion and the area of the bottom of the washing tub 100 outside the periphery of the mounting through hole to contact the laundry, preventing the existence of a cleaning dead angle where dirt is easily attached.

[0108] In the third specific embodiment, the stirring shaft 300 penetrates the mounting through hole provided in the bottom of the washing tub 100 to extend into the interior of the washing tub 100, the mounting portion is sleeved on the upper end of the stirring shaft 300, and there is a small gap between the lowermost end of the mounting portion and the bottom of the washing tub 100. The difference between the outer diameter and the inner diameter of the bottom of the mounting portion is small enough, so that the outer surface of the mounting portion can contact the laundry during washing, and the area of the bottom of the washing tub 100 outside the periphery of the mounting through hole can also contact the laundry, preventing the existence of a cleaning dead angle where dirt is easily attached. Preferably, the outer side wall of the mounting portion and the side wall of the stirring shaft 300 are smoothly connected, further avoiding the possibility of a cleaning dead angle.

[0109] For the case that the maximum diameter Dmax of the water stirring member 200 is located at or close to the top of the water stirring member 200, as a specific embodiment, as shown in Figure 2 The water stirring member 200 further comprises a water stirring disc 230, which is connected to the upper end of the support column 210, and the outer periphery of the water stirring disc 230 forms the maximum diameter Dmax of the water stirring member 200. The upper end of the water stirring rib 220 is connected to the lower side surface of the water stirring disc 230, preventing the existence of dead angles between the water stirring rib 220 and the water stirring disc 230, which are not in contact with the laundry C and are easy to hide dirt.

[0110] Further, the water stirring member 200 of the present embodiment forms a guide surface extending to the outer periphery below the maximum diameter Dmax. During washing, the laundry C lifted to the position below the maximum diameter Dmax of the water stirring member 200 moves along the guide surface to the outer periphery. More specifically, in the present embodiment, the guide surface comprises the lower side surface of the water stirring disc 230.

[0111] Preferably, a transition curved surface is arranged between the upper end of the side wall of the support column 210 and the lower side surface of the water stirring disc 230. More preferably, a rounded transition is arranged between the two side surfaces of the water stirring rib 220 and the lower side surface of the water stirring disc 230. In this way, the dead angles on the water stirring member 200 that are difficult to clean are further reduced.

[0112] As a specific embodiment, the upper end of the water stirring rib 220 of the present embodiment is away from the side of the support column 210 and coincides with the outer periphery of the water stirring disc 230, so that the radial dimension of the water stirring rib 220 along the washing tub 100 is maximized, which can strengthen the stirring force of the washing water and enhance the washing effect.

[0113] The washing equipment with the washing tub assembly of the present embodiment can drive the laundry C to move along a circular path below the maximum diameter Dmax of the water stirring member 200 for washing by controlling the relative rotation between the water stirring member 200 and the washing tub 100 during washing of the laundry C.

[0114] Specifically, in the bottom region of the washing tub 100, the stirring action of the water stirring member 200 on the water flow drives the water flow to have a radial flow trend along the washing tub 100, which in turn drives the laundry C to move along the bottom of the washing tub 100 to the central region. The laundry C gathered to the center contacts the side surface of the water stirring member 200 and is lifted upward under the rotation of the water stirring member 200 until it moves to the lower side of the maximum diameter Dmax of the water stirring member 200. At the lower side of the maximum diameter Dmax of the water stirring member 200, the upward movement trend of the water flow and the laundry C is blocked, and they move along the guide surface at the lower side of the maximum diameter Dmax of the water stirring member 200 to the outer periphery, and finally fall back to the bottom of the washing tub 100 under the action of gravity and the water flow in the region close to the wall of the washing tub 100 or after contacting the wall of the washing tub 100.

[0115] In this embodiment, the water-stirring component 200 installed inside the washing tub 100 forms a maximum diameter Dmax at a certain distance from the bottom of the tub. This allows the clothes C to be washed below the maximum diameter Dmax, exposing most of the bottom surface of the washing tub 100 to the washing water, enabling it to contact the clothes C being washed. During the washing process, the clothes C can contact the bottom of the washing tub 100 and the outer surface of the water-stirring component 200 below the maximum diameter Dmax, generating friction. This effectively avoids the problem of cleaning dead zones between the water-stirring component 200 and the washing tub 100, which easily accumulate lint and dirt.

[0116] On the other hand, during the washing process, the agitator 200 can cause the clothes C to gather from the bottom of the tub towards the center, then be lifted to a certain height, and then guide the clothes C to move outward and fall down, thus moving around the agitator 200 along a circular path, which can both enhance the washing effect and prevent the clothes C from getting tangled.

[0117] Example 2

[0118] like Figure 14 and Figure 15 As shown, this embodiment provides a washing tub assembly for a washing device, and a washing device having the washing tub assembly. The washing tub assembly provided in this embodiment differs from that in Embodiment 1 above in that: below the maximum diameter Dmax of the agitator 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.

[0119] In this embodiment, a raised agitator rib 220 is also provided on the side wall of the support column 210. However, unlike in Embodiment 1 above, the radial dimension of the agitator rib 220 along the washing tub 100 can remain constant with increasing height, or it can gradually or progressively change. Because the distance between the side wall of the support column 210 and the tub wall of the washing tub 100 decreases with increasing height, the distance between the side of the agitator rib 200 and the tub wall of the washing tub 100 also shows a decreasing trend with increasing height. Similar to Embodiment 1 above, in this embodiment, clothes can also be washed within the space formed by the bottom of the washing tub 100, the side wall of the support column 210, and the tub wall of the washing tub 100.

[0120] In the specific scheme of the embodiment, the support column 210 comprises a first extension section 211 and a second extension section 212 arranged below and connected to the maximum diameter Dmax of the water stirring member 200. The sidewall of the first extension section 211 extends upward from the bottom of the washing tub 100. The sidewall of the second extension section 212 extends outward from the upper end of the first extension section 211 and is inclined upward, and extends to the height of the maximum diameter Dmax of the water stirring member 200, so that the laundry can be washed below the sidewall of the second extension section 212 and move outward along the sidewall of the second extension section 212.

[0121] It should be noted that the sidewall of the first extension section 211 extends upward from the bottom of the washing tub 100, which can be vertically upward, or inclined upward relative to the vertical direction, gradually approaching or moving away from the tub wall of the washing tub 100, or extending upward along a curve with large curvature and gradually approaching or moving away from the tub wall of the washing tub 100.

[0122] As a specific embodiment, the sidewall of the first extension section 211 extends along a straight line and is inclined outward at a small angle relative to the vertical direction. The sidewall of the second extension section 212 has a larger angle between the vertical direction relative to the sidewall of the first extension section 211, and the angle between the sidewall of the second extension section 212 and the vertical direction gradually increases with the increase of the height, forming a curved surface curved toward the axis.

[0123] In the embodiment, the upper end of the support column 210 is also provided with a water stirring disc 230. Specifically, the upper end of the second extension section 212 is connected to the lower side surface of the water stirring disc 230. The support column 210 of the water stirring member 200 has the above structure, which effectively reduces the problem of cleaning dead angle that the laundry cannot contact between the upper end of the support column 210 and the lower side surface of the water stirring disc 230.

[0124] In a detailed scheme, the upper end of the sidewall of the second extension section 212 coincides with the outer periphery of the water stirring disc 230, so that the lower side surface of the water stirring disc 230 is completely covered by the upper end of the support column 210.

[0125] In the preferred scheme of the embodiment, as shown in Figure 15 The upper side surface of the water stirring disc 230 is a curved surface with the middle region higher than the outer peripheral region, and the stirring part 231 protruding is arranged on the curved surface. When the water level in the washing tub 100 is higher than the top of the water stirring disc 230, the stirring part 231 can stir the washing water above the water stirring disc 230 and rub the laundry above the water stirring disc 230 when the water stirring member 200 rotates, thereby enhancing the washing effect.

[0126] Further, in the embodiment, the side wall of the second extending section 212 forms a first guide surface 213 for guiding the laundry below the first guide surface 213 to move outwardly in the washing process. The side wall of the first extending section 211 forms a second guide surface 214 for guiding the laundry to move upwardly to the first guide surface 213 in the washing process.

[0127] Specifically, in the washing process, the washing equipment using the washing tub assembly in the embodiment rotates the water stirring member 200 relative to the washing tub 100, and the laundry moves to the central area along the bottom of the washing tub 100, then moves upwardly along the first guide surface 213 to the second guide surface 214, moves outwardly under the guidance of the second guide surface 214, and then falls in the area close to the wall of the washing tub 100 to form a circular path. On the one hand, the laundry in the washing tub can be stirred to improve the washing effect, and on the other hand, the probability of the laundry winding around the center is reduced.

[0128] As a specific embodiment of the embodiment, the included angle between the side wall of the first extending section 211 and the second extending section 212 and the vertical direction is the same at the connecting position of the two extending sections. That is, the first guide surface 213 and the second guide surface 214 have the same inclination angle at the connecting position, and smooth transition connection is achieved.

[0129] As another specific embodiment, the inclination angle of the side wall of the second extending 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 extending section 211 relative to the vertical direction, so that the included angle at the connecting position of the first guide surface 213 and the second guide surface 214 is less than 180° but close to 180°. In this way, when the laundry moves upwardly along the second guide surface 214 to the first guide surface 213, the laundry can be buffered to some extent, and the tendency of the laundry to move outwardly in the form of rolling is enhanced.

[0130] In a further scheme of the embodiment, the water stirring ribs 220 have a certain extension length along the axial direction of the washing tub 100, extending from the side wall of the first extending section 211 to the side wall of the second extending section 212. A plurality of water stirring ribs 220 are arranged at intervals along the circumferential direction of the supporting column 210, and the interval angle between the adjacent two water stirring ribs 220 is such that the laundry can be washed in the interval area between the adjacent two water stirring ribs 220, and the laundry can contact the side wall of the first extending section 211 to move upwardly along the side wall of the first extending section 211, that is, the second guide surface 214.

[0131] In this way, the area between the side walls of the first extending section 211 and the second extending section 212 and the adjacent two water stirring ribs 220 can contact the laundry, and no dead angle where dirt is easily accumulated is generated.

[0132] Further, in the embodiment, the radial dimension of the water stirring ribs 220 increases first and then decreases from the lower end to the upper end.

[0133] As a specific embodiment, the cross-sectional shape of the water stirring ribs 220 parallel to the radial direction of the washing tub 100 is approximately shuttle-shaped. The outer peripheral edge of the water stirring ribs 220 extends from the lower end to the upper end, and the included angle between the extending direction and the vertical direction gradually decreases, so that the outer peripheral edge of the water stirring member 200 forms a curve bending towards the tub wall of the washing tub 100. The upper end of the outer peripheral edge of the water stirring ribs 220 coincides with the outer periphery of the water stirring disc 230.

[0134] The water stirring ribs 220 have the above structure, can form a Coanda effect during washing, and drive 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 trend adhering to 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 outward. In this way, the lifting force of the water flow on the clothes in the area close to the axis can be enhanced, the clothes are driven to move upward to the first guide surface 213, and finally form a circular path.

[0135] It can be understood that the clothes moving towards the central area along the bottom of the tub can also be lifted along the outer peripheral edge of the water stirring ribs 220 after contacting the water stirring ribs 220, move to the maximum diameter Dmax of the water stirring member 200, and then move outward under the action of inertia and centrifugal force, and finally fall along the tub wall of the washing tub 100 to the bottom of the tub.

[0136] In the preferred embodiment of the present 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 ribs 220 and the bottom of the washing tub 100, so as to avoid the existence of a cleaning dead angle between the water stirring ribs 220 and the bottom. Specifically, the bottom of the support column 210 is provided with a mounting portion 210-1 for connecting the stirring shaft 300, the bottom of the washing tub 100 has a groove structure for mounting the mounting portion 210-1, the mounting portion 210-1 and the groove structure are rotatably inserted and matched, the stirring shaft 300 for driving the water stirring member 200 to rotate penetrates through the mounting through hole in the bottom wall of the groove structure, and is fixed by being inserted into the mounting portion 210-1 from the lower end. The lower end of the water stirring ribs 220 is at least flush with the upper end of the mounting portion 210-1, and preferably higher than the upper end of the mounting portion 210-1. A water seal structure is arranged between the mounting portion 210-1 and the groove structure, for preventing dirt from being hidden in the interior of the groove structure.

[0137] More preferably, the connection positions of the water stirring ribs 220 and the support column 210 are all provided with smooth transition fillet structures, so that there is almost no cleaning dead angle on the water stirring member 200 where dirt is easy to accumulate, and the cleaning and sanitation of the interior of the washing tub 100 are maximally ensured.

[0138] More preferably, the outer peripheral edge of the water-stirring rib 220 and the two side surfaces of the water-stirring rib 220 have rounded corner transitions to avoid sharp corner structures that may scratch and damage clothing.

[0139] It is understandable that by setting a certain distance between the lower end face of the assembly part and the bottom of the washing tub, or by setting the difference between the outer diameter and the inner diameter of the assembly part to be small enough, the outer surface of the assembly part (including the outer wall and the lower end face) and the area of ​​the bottom of the washing tub located around the mounting hole can contact the clothes, thus preventing the existence of cleaning dead corners. In the above solutions, the bottom of the washing tub does not need to have a groove structure, but can adopt a structure where the upper surface of the tub bottom is flat, preferably a structure where the area around the mounting hole protrudes upwards.

[0140] In one specific embodiment, the thickness of the water-stirring rib 220 gradually decreases radially outward in the circumferential direction, and along the axial direction, the thickness of the middle region of the water-stirring rib 220 is greater than the thickness of the upper and lower ends.

[0141] In this embodiment, the change in distance between the side of the agitator 200 and the wall of the washing tub 100 is formed by the change in the cross-sectional dimensions of the support column 210 itself. This also creates a structure where the distance between the maximum diameter Dmax and the bottom of the washing tub 100 is a certain, ensuring that clothes are washed below the maximum diameter Dmax of the agitator 200. Simultaneously, the side wall of the support column 210 forms a first guide surface 213 and a second guide surface 214 that guide the movement of clothes during washing. This effectively drives the clothes to move and tumble along a circular path below the maximum diameter Dmax of the agitator 200, resulting in better washing performance and preventing clothes from tangling.

[0142] Example 3

[0143] like Figures 14 to 16 As shown, this embodiment is a further limitation of the above embodiment two. The water stirring component 200 includes an assembly part 210-1 and a water stirring part 240 extending upward from the assembly part 210-1. The assembly part 210-1 is configured as a solid structure, and the water stirring part 240 is at least partially configured as a hollow structure. For example, the water stirring part 240 has a cavity provided axially from the top end toward the assembly part 210-1.

[0144] Specifically, in this embodiment, the assembly part 210-1 is a solid column, which can increase the connection strength of the water-stirring component 200. The water-stirring part 240 has an integrally formed hollow structure, and the water-stirring part 240 is formed on the top of the assembly part 210-1. The assembly part 210-1 can also seal the lower end of the hollow structure of the water-stirring part 240.

[0145] As a specific embodiment, the water stirring member 200 comprises a support column 210, and water stirring ribs 220 arranged on the side wall of the support column 210, protruding in the radial direction of the support column or in a direction close to the radial direction away from the axis of the support column 210, extending in the length direction along the axial direction of the support column, and extending in the width direction away from the outer periphery of the support column, which can be arranged in the radial direction or deviated from the radial direction.

[0146] In the embodiment, the support column 210 comprises an assembly part 210-1 and a hollow column 210-8 coaxially connected to the upper part of the assembly part 210-1, the assembly part 210-1 is a solid column, preferably a cylindrical column, and the hollow column 210-8 extends upward from the upper end surface of the assembly part 210-1. The outer diameter of the connection between the hollow column 210-8 and the assembly part 210-1 can be greater than the diameter of the assembly part 210-1, or can be less than or equal to the diameter of the assembly part 210-1; the outer peripheral wall of the hollow column 210-8 and the outer peripheral wall of the assembly part 210-1 are smoothly transitioned and extend upward.

[0147] The water stirring part 240 has a horizontal cross section with the maximum radius at a certain height from the upper end of the assembly part 210-1. A water stirring disc 230 is arranged at the top end of the support column 210, the maximum diameter Dmax of the water stirring part 240 is formed by the outer periphery of the water stirring disc 230, and the top surface of the water stirring disc 230 is a curved surface protruding upward. The hollow column 210-8 forms a cavity 210-9 inside which has a shape similar to the outer shape of the support column 210.

[0148] Preferably, the water stirring ribs 220 are also arranged in a hollow structure.

[0149] Further preferably, the internal space of the water stirring ribs 220 is in communication with the cavity 210-9 inside the hollow column 210-8.

[0150] Further preferably, the lower end of the water stirring ribs 220 at least partially extends to the outer peripheral wall of the assembly part 210-1, and is integrally formed with the assembly part 210-1, thereby further strengthening the connection between the assembly part 210-1 and the water stirring part 240.

[0151] In the embodiment, the water stirring part 240 is connected to the stirring shaft 300 which can rotate through the bottom of the washing tub 100, so that the water stirring member 200 can rotate relative to the washing tub 100.

[0152] Specifically, the assembly part 210-1 and the stirring shaft 300 are circumferentially positioned by spline, rotate together, and are axially positioned by screw 210-7.

[0153] In the embodiment, the assembling part 210-1 is provided with a spline groove 210-6 extending coaxially upward from the bottom end surface of the assembling part 210-1, and the spline groove 210-6 is at least partially sleeved on the upper end of the stirring shaft 300 and is keyed connected with the stirring shaft 300. The spline groove 210-6 is formed on the assembling part 210-1 of the water stirring member 200.

[0154] In the embodiment, the top of the water stirring member 200 is provided with an opening communicating with the cavity 210-9 in the hollow column, a screw 210-7 passes through the opening into the cavity 210-9 and is connected with the stirring shaft 300 keyed connected in the assembling part 210-1, and the water stirring member 200 is fixedly connected with the stirring shaft 300 in the axial direction. In order to avoid water entering the cavity 210-9, a plugging part is installed at the opening.

[0155] Preferably, the top of the water stirring member 200 is provided with a sealing groove 210-4 which is recessed coaxially downward from the top surface of the water stirring disc 230. The groove bottom of the sealing groove 210-4 is provided with an opening communicating with the cavity 210-9.

[0156] Specifically, the upper end of the assembling part 210-1 is provided with a through hole, preferably a threaded hole, the rod part of the screw 210-7 is screwed in the threaded hole through the top of the assembling part 210-1, and the head part of the screw 210-7 abuts against the top of the assembling part 210-1. The operator disassembles and assembles the screw 210-7 through the opening on the groove bottom of the sealing groove 210-4 and the cavity 210-9 of the hollow column 210-8. The screw is preferably a countersunk screw.

[0157] A sealing cover 210-5 for closing the upper end of the water stirring member 200 is arranged at the sealing groove 210-4 to avoid washing water entering the inside of the water stirring member 200.

[0158] Specifically, the sealing cover 210-5 includes a flat plate part and a plug-in part, the flat plate part covers the slot of the sealing groove 210-4 and is embedded on the top of the water stirring member 200, and the plug-in part is plugged in the sealing groove 210-4 and is in interference fit with the sealing groove 210-4.

[0159] The top of the flat plate part is in the same plane with the top of the water stirring member 200.

[0160] The sealing groove 210-4 includes a first section and a second section with increasing diameters from top to bottom, and the lower end of the plug-in part is provided with a limiting convex protruding from the outer wall of the lower end of the plug-in part away from the axis of the water stirring member 200, and the limiting convex is engaged at the junction between the first section and the second section.

[0161] Preferably, the inner walls of the first and second sections of the sealing groove 210-4 are connected by a tapered surface that slopes downwards away from the axis of the agitator 200. The shape of the limiting protrusion is adapted to the shape between the first and second sections of the sealing groove 210-4. The outer circumferential surface of the limiting protrusion fits against the inner wall of the second section, and the top of the limiting protrusion fits against the tapered surface between the first and second sections of the limiting groove. Preferably, the bottom of the limiting protrusion is a tapered surface with an outer diameter that gradually decreases from top to bottom, and the outer diameter of the bottom of the limiting protrusion is smaller than the inner diameter at the opening of the sealing groove 210-4.

[0162] In this embodiment, a sealing ridge extending circumferentially along the middle of the insertion portion is provided, and the insertion portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 through the sealing ridge. Preferably, the sealing ridge extends circumferentially along the insertion portion and is provided in multiple rings spaced apart axially along the insertion portion.

[0163] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring component 200 to improve the smoothness of the insertion of the sealing cap 210-5.

[0164] In this embodiment, a specific assembly structure for the water-stirring component 200 and the stirring shaft 300 is provided. By making the water-stirring part 240 of the water-stirring component 200 hollow, the water-stirring component 200 and the stirring shaft 300 can be fixed by screws 210-7 from top to bottom. At the same time, the overall weight of the water-stirring component 200 is reduced, thereby further reducing the energy consumption of the motor that drives the water-stirring component 200 to rotate. By setting the sealing cover 210-5, washing water can be prevented from entering the interior of the water-stirring component 200, thereby preventing lint or dirt from entering with the washing water and remaining inside the water-stirring component 200 and being difficult to clean.

[0165] Example 4

[0166] like Figures 14 to 16 As shown, this embodiment is a further limitation of the above-described embodiments two or three. The water-stirring component 200 includes an assembly part 210-1 and a water-stirring part 240 extending upward from the assembly part 210-1. The stirring shaft 300 is rotatably connected to the assembly part 210-1 at the center of the bottom of the bucket.

[0167] In one specific embodiment, the distance from the side wall of the assembly part 210- to the inner surface of the circumferential wall of the washing tub 100 is close to the distance from the side wall of the agitator shaft 300 to the inner surface of the circumferential wall of the washing tub 100. More specifically, the distance from the side wall of the assembly part 210- to the inner surface of the circumferential wall of the washing tub 100 is slightly smaller than the distance from the side wall of the agitator shaft 300 to the inner surface of the circumferential wall of the washing tub 100.

[0168] In this way, the bottom surface of the washing tub 100 is substantially completely exposed to the washing space above, avoiding the problem of dirt being hidden in the bottom of the tub.

[0169] In this embodiment, the dewatering shaft 110 connected to the washing tub 100 is sleeved on the stirring shaft 300, and a sealing structure 120 is arranged between the upper end of the dewatering shaft 110 and the stirring shaft 300, so that the dewatering shaft 110 and the stirring shaft 300 are sealingly connected in a relative rotation manner, preventing water from entering between the dewatering shaft 110 and the stirring shaft 300.

[0170] Specifically, the sealing structure 120 is sleeved on the stirring shaft 300, and the outer peripheral wall of the sealing structure 120 is in close contact with the inner peripheral wall of the dewatering shaft 110.

[0171] As a specific embodiment, the upper end surface of the sealing structure 120 is flush or substantially flush with the inner surface of the tub bottom, thereby preventing the dewatering shaft 110 and the stirring shaft 300 from forming a gap that is easy to hide dirt.

[0172] The "substantially flush" mentioned above means that the upper end surface of the sealing structure 120 can be slightly higher than the inner surface of the tub bottom, or slightly lower than the inner surface of the tub bottom.

[0173] For the structure in which the upper end surface of the sealing structure 120 is slightly higher than the inner surface of the tub bottom, no concave gap is formed between the dewatering shaft 110 and the stirring shaft 300. For the structure in which the upper end surface of the sealing structure 120 is slightly lower than the inner surface of the tub bottom, although a concave gap is formed, the size of the concave gap is very small, and the scouring force of the water flow when washing is sufficient to carry out the lint and dirt at this position, so that there is no dirt remaining.

[0174] As a specific embodiment, the lower end surface of the water stirring member 200, i.e., the lower end surface of the fitting portion 210-1, is at least partially arranged opposite to the upper end surface of the sealing structure 120. The fitting portion 210-1 is sleeved on the upper end of the stirring shaft 300, and the diameter of the lower end of the fitting portion 210-1 is greater than the diameter of the stirring shaft 300.

[0175] Further, the diameter of the lower end of the fitting portion 210-1 is greater than the outer diameter of the sealing structure 120.

[0176] In a specific scheme, the difference between the diameter of the lower end of the fitting portion 210-1 and the outer diameter of the sealing structure 120 is close to the wall thickness of the fitting portion 210-1 in the radial direction.

[0177] In this embodiment, the specific assembly relationship between the bottom of the water stirring member 200 and the stirring shaft 300 and the tub bottom further ensures that the tub bottom does not hide dirt.
