Description

Technical Field

[0001] The invention belongs to the technical field of clothing processing, and in particular relates to a washing device. Background Art

[0002] As a convenient clothes washing device, washing machines have been widely used in people's lives. Existing washing machines are divided into drum washing machines and pulsator washing machines, among which pulsator washing machines are popular with users due to their good washing effect.

[0003] A pulsator washing machine generally includes a washing tub and a pulsator, wherein the pulsator is arranged at the bottom of the washing tub. When the pulsator washing machine is working, the rotation of the pulsator drives the washing water in the washing tub to rotate, thereby washing the clothes to be washed in the washing tub.

[0004] For example, Chinese utility model patent application number CN201520398758.5 ​​discloses a pulsator washing machine, which belongs to the field of electrical appliances and solves the technical problem of insufficient cleaning ability of washing machines in the prior art. The pulsator washing machine provided by the utility model comprises a machine body, a water tub and a washing and dehydrating tub. A rotatable pulsator disc is provided at the bottom of the washing and dehydrating tub, and an intermediate column coaxial with the pulsator disc is provided on the pulsator disc. A detergent inlet and a detergent outlet are provided on the intermediate column, and the detergent inlet and the detergent outlet are connected, and the detergent outlet is connected to the washing space above the pulsator disc.

[0005] Existing pulsator washing machines usually have a flat circular pulsator disc, which fits the bottom of the washing tub. During use, the portion between the pulsator disc and the bottom of the washing tub does not come into contact with the clothes in the washing tub. During washing, dirt and lint on the clothes are easily accumulated in the gap between the bottom of the pulsator disc and the washing tub, and cannot be effectively cleaned by simply flushing. In addition, dirt and lint are easily bred with bacteria when they are in a humid environment for a long time, which brings a bad user experience.

[0006] Therefore, designing a washing device that can avoid dirt accumulation between the water stirring portion of the water stirring member and the bottom of the washing tub has become a technical problem that needs to be solved urgently by those skilled in the art.

[0007] In addition, in order to remove the dirt accumulated at the bottom of the barrel, the impeller and its components need to be disassembled for cleaning. However, in the prior art, the impeller is mostly installed and locked by screws, and special tools need to be used for disassembly, resulting in a cumbersome disassembly and assembly process of the impeller.

[0008] The Chinese invention patent with application number CN201910501974.0 discloses a pulsator assembly and a washing machine. The pulsator assembly includes a pulsator body detachably connected to the output shaft of the washing machine, and a positioning body fixed on the pulsator body, and the positioning body can fix a disassembly body through a snap-fit ​​structure; the positioning body includes a positioning cavity, a limiter, a clamping member and an insert, and the volume of the positioning cavity increases in the direction in which the pulsator body is separated from the output shaft; the top of the limiter is connected to the disassembly body; the clamping member is limited by the limiter; the insert is connected to the output shaft, and a limiter groove is provided on it; the insert is inserted into the positioning cavity and the limiter from the bottom, and the clamping member can enter and exit the limiter groove in the radial direction of the insert. When assembling, the clamping member is clamped in the limiter groove to clamp the insert, and the pulsator body is locked in the axial direction; when disassembling, the disassembly body is rotated and pulled, the circumferential space of the clamping member is increased, the clamping of the insert is released, and the pulsator body is separated from the output shaft, which solves the problem of cumbersome disassembly of the washing machine pulsator. However, the above scheme is only applicable to the installation of impellers with smaller axial lengths, and is not applicable to water-stirring components with larger axial lengths, such as stirring columns, stirring rods, stirring rods, etc. Water-stirring components with larger axial lengths can only be installed using traditional, difficult-to-disassemble installation methods such as screws.

[0009] Therefore, designing a washing device that can improve the convenience of disassembly and assembly of a water-stirring component with a large axial length has become a technical problem that needs to be solved urgently by those skilled in the art.

[0010] In view of this, the present invention is proposed. Summary of the invention

[0011] An object of the present invention is to provide a washing device to solve the problem that dirt is easily accumulated between the impeller disc of the water stirring member and the bottom of the barrel of the existing washing device.

[0012] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0013] A washing device comprises a washing tub and a water stirring member, wherein the water stirring member comprises:

[0031] Furthermore, a first elastic member is provided between the driven part and the top inner wall of the installation cavity, for driving the driven part to move downward.

[0032] Further, the driven part includes a hollow limiting column arranged on the positioning cavity or the limiting member and an extension plate extending from the outer wall of the hollow limiting column in a radial direction away from the axis direction of the water stirring member;

[0033] The driving part is columnar, and an abutting part is provided at one end of the driving part close to the axis of the water stirring member, which protrudes toward the axis of the water stirring member and abuts against one end of the extension plate away from the axis of the water stirring member.

[0034] Furthermore, a first guide groove is provided at one end of the abutting portion close to the axis of the water-stirring member, and the end of the extension plate is inserted into the first guide groove and abuts against the bottom of the first guide groove; the end of the extension plate is provided as an inclined surface inclined from bottom to top in a direction away from the axis of the water-stirring member, and the bottom of the first guide groove is in contact with the end of the driven portion;

[0035] Preferably, a relief groove for evading the upper end of the extension plate is provided on the driving portion above the abutting portion.

[0043] It should be noted that the maximum radius of the water-stirring component refers to the maximum radius of the horizontal section of the water-stirring component. The radius of the horizontal section of the water-stirring component refers to the distance from the farthest point from the center of rotation to the center of rotation on the horizontal section of the water-stirring component.

[0044] Specifically, if the horizontal cross section of the water stirring member is circular, the radius is the radius R1 of the circular cross section. If the horizontal cross section of the water stirring member is non-circular, the radius is the distance R2 from the farthest point on the cross section to the rotation center.

[0045] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0046] 1. The water stirring component of the present invention eliminates the impeller disk. The water stirring component includes an assembly part and a water stirring part.

[0076] Embodiment 1

[0077] like Figures 1 to 4 As shown, in an embodiment of the present invention, 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.

[0078] In this embodiment, the washing tub 100 is a tub without holes.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] In the present embodiment, a water-stirring member 200 is provided to extend along the axial direction of the washing tub 100, and a water seal structure 500 is provided between the bottom of the tub where the clothes can reach and the circumferential surface of the lower end of the water-stirring member 200. The bottom of the washing tub 100 outside the water seal structure 500 can be in contact with the clothes, and the friction between the clothes and the inner surface of the bottom of the tub is utilized to prevent lint or other dirt from adhering to the inner surface of the bottom of the tub. At the same time, the water seal structure 500 can prevent the washing water from flushing the dirt to a position where the clothes cannot reach, thereby effectively avoiding the problem of dirt and grime being easily hidden and difficult to clean between the water-stirring member 200 and the bottom of the tub, thereby improving the user experience.

[0083] In this embodiment, the water stirring member 200 extends upward from the bottom of the washing tub 100, and includes a support column 210 and a water stirring rib 220 arranged on the support column 210. The support column 210 extends along the axial direction of the washing tub 100, and the water stirring rib 220 is arranged on the circumferential side of the support column 210 and extends along the length direction of the support column 210. The lower end of the support column 210 is rotatably engaged with the bottom of the washing tub 100.

[0084] An installation groove 100-1 is provided at the bottom of the barrel closest to the center where the clothes can reach, and the lower end of the support column 210 is inserted into the installation groove 100-1. The water seal structure 500 is provided between the groove wall of the installation groove 100-1 and the lower end circumference of the support column 210.

[0085] Specifically, in this embodiment, the stirring shaft 300 of the washing device coaxially extends into the washing tub 100 , the lower end of the support column 210 of the water stirring member 200 is connected to the upper end of the stirring shaft 300 , and the stirring shaft 300 is used to drive the water stirring member 200 to rotate.

[0086] 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.

[0087] 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.

[0088] The water seal structure 500 is annular and is arranged between the groove wall of the installation groove 100-1 and the lower end circumference of the support column 210; the outer periphery of the water seal structure 500 is connected to the groove wall of the installation groove 100-1, and the inner periphery of the water seal structure 500 is elastically abutted against the lower end circumference of the support column 210.

[0090] The mounting groove is coaxially arranged at the notch of the mounting groove 100-1, and the diameter of the mounting groove is larger than the diameter of the mounting groove 100-1. The water seal structure 500 is arranged in the mounting groove, and its lower end surface is in contact with the groove bottom of the mounting groove, and its upper end surface is substantially flush with the inner surface of the barrel bottom. 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.

[0091] In this embodiment, the "upper end surface of the water seal structure 500 is basically flush with the inner surface of the barrel bottom" can specifically mean that the upper end surface of the water seal structure 500 is flush with the inner surface of the barrel bottom, or that the upper end surface of the water seal structure 500 protrudes from the inner surface of the barrel bottom, or that the upper end surface of the water seal structure 500 is slightly lower than the inner surface of the barrel bottom.

[0092] like Figures 2 to 4 As shown, in this embodiment, the water seal structure 500 includes a rubber body and a spring ring 500-5. The rubber body is arranged in the embedding groove, including a rubber body main body adapted to the embedding groove, and a sealing lip 500-4 arranged between the inner periphery of the rubber body main body and the lower end circumference of the support column 210 and elastically abutting. The spring ring 500-5 is sleeved on the rubber body. By sleeve-arranging the spring ring 500-5 on the rubber body, the sealing effect of the water seal structure 500 can be enhanced.

[0093] Preferably, in this embodiment, the spring ring 500 - 5 is hidden in the embedding groove, which can prevent the spring ring 500 - 5 from contacting with washing water, thereby preventing the spring ring 500 - 5 from rusting and improving the stability of the effect of the water seal structure 500 .

[0131] Embodiment 2

[0132] like Figures 5 to 10As shown, in an embodiment of the present invention, a washing device is introduced, the washing device includes a washing tub assembly, 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.

[0133] In this embodiment, the washing tub 100 may include an inner tub and an outer tub coaxially sleeved outside the inner tub. When washing clothes, there may be water or no water between the inner tub and the outer tub, and the water stirring member 200 is arranged on the inner side of the bottom of the inner tub.

[0134] Alternatively, the washing tub 100 may be a tub without holes, and the washing tub 100 is used for containing both clothes and washing water.

[0135] The washing device further comprises a driving device, which is in driving connection with the washing tub 100 and the water stirring member 200. Specifically, the output shaft of the driving device is respectively in driving connection with the stirring shaft 300 and the dehydrating shaft. The stirring shaft 300 is connected to the water stirring member 200 and is 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.

[0136] The water stirring member 200 of the existing washing equipment is usually a flat circular impeller, and the water stirring part of the water stirring member 200 is generally a bottom disc-shaped stirring part, that is, the impeller disc. When washing, impurities such as lint on the clothes fall off and are easily accumulated in the gap between the bottom surface of the impeller and the washing tub 100.

[0137] In this embodiment, the water stirring member 200 includes an assembly portion 210-1 and a water stirring portion arranged on the top of the assembly portion 210-1. The assembly portion 210-1 is arranged above the inner surface of the barrel bottom, or the assembly portion 210-1 at least partially extends to the inner surface of the barrel bottom of the washing barrel 100, and the water stirring portion extends upward from the top of the assembly portion 210-1; the portion of the assembly portion 210-1 located between the water stirring portion and the barrel bottom can contact the clothes in the washing barrel 100.

[0138] Specifically, in this embodiment, a mounting through hole cooperating with the stirring shaft 300 is provided on the bottom of the washing tub 100 , and the stirring shaft 300 extends from the mounting through hole to the inside of the washing tub 100 , and the stirring shaft 300 and the washing tub 100 are coaxially arranged.

[0139] The water stirring member 200 is assembled with the stirring shaft 300 via the assembly portion 210 - 1 .

[0140] In this embodiment, the assembly portion of the water-stirring component is sleeved on the upper end of the stirring shaft, and the assembly portion and the stirring shaft are key-connected. The assembly portion and the stirring shaft are circumferentially positioned by splines. Preferably, the assembly portion of the water-stirring component and the stirring shaft are axially positioned by a clamping structure or screws.

[0141] In this embodiment, the assembly part 210-1 corresponds to the mounting through hole in the middle of the barrel bottom, and the diameter of the assembly part is greater than the diameter of the stirring shaft. Preferably, the inner surface of the barrel bottom of the washing barrel 100 is provided with a mounting groove 100-1, and the lower end of the assembly part 210-1 is provided with a connecting part 215 rotatably inserted in the mounting groove 100-1, and the radial dimension of the connecting part 215 is greater than or equal to the radial dimension of the portion of the assembly part 210-1 between the connecting part 215 and the water stirring part, and is smaller than the radial dimension of any horizontal cross section of the water stirring part.

[0142] In this embodiment, the installation groove 100-1 is arranged around the stirring shaft 300, the installation through hole is arranged on the bottom of the installation groove 100-1, and the stirring shaft passes through the installation groove 100-1 and extends into the washing tub 100. The assembly portion of the water stirring member is sleeved on the stirring shaft 300, the diameter of the connecting portion 215 at the bottom of the assembly portion 210-1 is adapted to the diameter of the installation groove 100-1, and a rotation pair is formed between the outer edge of the connecting portion 215 and the groove wall of the installation groove 100-1.

[0143] The connecting portion 215 is cylindrical, and the assembly portion 210-1 between the connecting portion 215 and the water stirring portion is columnar. It can be a columnar shape with a diameter gradually increasing from top to bottom, a columnar shape with a diameter gradually decreasing from top to bottom, a cylindrical shape, or a prism shape. It is only necessary to ensure that the clothes in the washing tub can contact the part of the assembly portion placed between the connecting portion and the water stirring component.

[0144] In this embodiment, even if the gap between the water stirring member 200 and the bottom of the barrel is extremely small, there is still a certain possibility of dirt accumulation. Since the space in the gap is relatively narrow, it is inconvenient for users to operate, and users usually need to remove the impeller to clean the dirt in the gap. Existing washing equipment usually installs the water stirring member 200 on the stirring shaft 300 of the washing equipment through screws 210-7. This structure is not conducive to the user to disassemble and assemble the water stirring member 200.

[0145] In this embodiment, an installation structure of a water stirring component 200 is also introduced. The installation structure is suitable for a water stirring component 200 with a large axial length. The glue component with a large axial length can specifically be a stirring column, a stirring rod, a stirring rod, etc.

[0146] like Figure 5As shown, in this embodiment, the mounting structure is disposed between the assembly portion 210 - 1 and the stirring shaft 300 of the washing device, so as to realize the axial positioning between the water stirring member 200 and the stirring shaft 300 .

[0147] like Figure 6 As shown, the installation structure includes an insert 401 arranged at the end of the stirring shaft 300 and a locking assembly arranged in the assembly portion 210-1 of the water stirring member 200. When the water stirring member 200 is installed, the insert 401 is at least partially inserted into the assembly portion 210-1, and the locking assembly in the assembly portion 210-1 locks the insert 401 along the axial direction of the water stirring member 200, thereby realizing the axial positioning between the water stirring member 200 and the stirring shaft 300.

[0148] Specifically, the locking assembly includes a positioning cavity 402 and a stopper 403, and the positioning cavity 402 and the stopper 403 are coaxially arranged. An installation cavity 210-2 is arranged in the assembly portion 210-1, and the positioning cavity 402 and the stopper 403 are arranged in the installation cavity 210-2.

[0149] The positioning cavity 402, the limiting member 403, and the insert 401 are coaxially arranged. When the water-stirring member 200 is installed, the insert 401 is inserted into the installation cavity 210-2 from the bottom of the assembly portion 210-1, and is inserted into the limiting member 403. The positioning cavity 402 and the limiting member 403 are close to each other, so as to lock the insert 401. The positioning cavity 402 and the limiting member 403 are far away from each other, so as to unlock the insert 401.

[0150] In this embodiment, the insert 401 is columnar, and the insert 401 can be coaxially arranged on the upper end of the stirring shaft 300 by any feasible method such as welding, bonding, molding, threaded connection, etc. A limiting groove is arranged on the insert 401, and the limiting groove is arranged around the peripheral wall of the insert 401; the limiting member 403 includes a limiting cavity 4031 and a clamping member 4032, and a limiting hole 4033 is provided on the side wall of the limiting cavity 4031, and the clamping member 4032 can enter and exit the limiting groove in the radial direction of the insert 401, and the limiting hole 4033 is used to limit the entry and exit path of the clamping member 4032 in the radial direction of the insert 401; the limiting member 403 is at least partially inserted in the positioning cavity 402, and the caliber of the positioning cavity 402 gradually increases in the direction in which the limiting member 403 is disengaged, and the inner wall of the positioning cavity 402 confines the clamping member 4032 in the limiting groove.

[0151] In this embodiment, the positioning cavity 402 and the stopper 403 have a tendency to approach each other. When the stirring assembly is installed, the insert 401 is inserted into the installation cavity 210-2 from the bottom of the assembly portion 210-1. During the insertion of the insert 401 into the locking assembly, the insert 401 first squeezes the stopper 403 to separate the positioning cavity 402 from the stopper 403. Under the action of the insert 401, the clamping member 4032 moves along the stopper hole 4033 in a direction away from the axis of the water stirring member 200. Under the stopper action of the positioning cavity 402, the clamping member 4032 will not completely disengage from the stopper hole 4033. At this time, the insert 401 can enter the stopper cavity 4031. When the clamping member 4032 corresponds to the limiting groove, the clamping member 4032 enters the limiting groove, and the limiting member 403 and the positioning cavity 402 move towards each other. Due to the effect of the gradually decreasing diameter of the positioning cavity 402, the clamping member 4032 enters the limiting member 403 from the limiting hole 4033 and is clamped in the limiting groove of the insert 401, thereby clamping the insert 401, thereby positioning the water stirring member 200 from the axial direction of the stirring shaft 300.

[0152] Preferably, in this embodiment, the inner wall of the positioning cavity 402 is configured as a frustum surface that is inclined in a direction away from the axis of the water stirring member 200 along the direction in which the stopper 403 escapes.

[0153] Preferably, in this embodiment, the limiting groove extends along the circumferential direction of the insert 401, and the limiting groove is configured such that the groove depth gradually increases along the direction in which the limiting member 403 is inserted into the positioning cavity 402. After the water stirring member 200 is installed, the clamping member 4032 abuts against the middle of the groove bottom of the limiting groove to ensure the locking effect of the clamping member 4032 on the insert 401, thereby preventing the water stirring member 200 from axial shaking when working.

[0154] Preferably, Figure 7 As shown, in this embodiment, the limiting cavity 4031 is configured as a column with an isosceles trapezoidal axial cross-section, and the side wall of the limiting cavity 4031 is configured as a frustum of which the diameter gradually increases in the direction of escaping the positioning cavity 402, and the inclination angle of the side wall of the limiting cavity 4031 in the direction of escaping the positioning cavity 402 away from the axis of the water stirring member 200 is less than or equal to the inclination angle of the inner wall of the positioning cavity 402 in the direction of escaping the limiting member 403 away from the axis of the water stirring member 200.

[0155] Preferably, Figures 7 to 9 As shown, the limiting holes 4033 are provided with a plurality of holes evenly arranged along the circumference of the limiting cavity 4031 , and each limiting hole 4033 is provided with a clamping member 4032 , and the clamping member 4032 is set to be a spherical shape that matches the shape of the limiting hole 4033 .

[0156] Preferably, three limiting holes 4033 are provided.

[0157] The bottom of the assembly portion 210-1 is provided with a through hole communicating with the installation cavity 210-2, and the through hole is adapted to the insert 401. Preferably, the aperture of the lower end of the through hole gradually increases from top to bottom, so as to improve the smoothness of the insertion of the insert 401.

[0158] The top of the insert 401 is preferably designed as a round head, and the clamping member 4032 is also preferably designed as a spherical ball, so that when the insert 401 is pushed into the limiting member 403, when the radial cross-section of the positioning cavity 402 becomes larger, the clamping member 4032 can more easily fall into the limiting groove of the insert 401.

[0159] In this embodiment, there is a tendency for the positioning cavity 402 and the limiting member 403 to approach each other to lock the insert 401, and an unlocking component is also provided between the outer periphery of the positioning cavity 402 or the limiting member 403 and the side wall of the assembly part 210-1 for driving the limiting cavity 4031 and the limiting member 403 to separate from each other to unlock the insert 401.

[0160] The unlocking assembly is arranged at the portion of the assembly portion 210 - 1 between the water stirring portion and the inner surface of the barrel bottom, so that the user can operate the unlocking assembly conveniently.

[0161] Specifically, in this embodiment, one of the positioning cavity 402 and the limiting member 403 is fixed to the assembly portion 210 - 1 , and the other can slide along the axial direction of the water-stirring member 200 .

[0162] In some possible embodiments, the limit member 403 is coaxially fixed on the bottom inner wall of the installation cavity 210-2, the positioning cavity 402 is coaxially arranged above the limit member 403, the opening of the positioning cavity 402 faces downward, the diameter of the positioning cavity 402 gradually increases from top to bottom, and the unlocking component is used to drive the positioning cavity 402 to move axially.

[0163] The insert 401 is inserted into the installation cavity 210-2 from the bottom of the self-assembly portion 210-1, and the upper end of the insert 401 abuts against the clamping piece 4032 in the limit member 403. At this time, the side of the clamping piece 4032 close to the axis of the water-stirring member 200 abuts against the upper end of the insert 401, and the side of the clamping piece 4032 away from the water-stirring member 200 abuts against the inner wall of the positioning cavity 402. Since the positioning cavity 402 tends to move toward the direction close to the limit member 403, the insert 401 cannot continue to be inserted.

[0164] The user operates the unlocking assembly to move the positioning cavity 402 upward. Since the inner wall of the positioning cavity 402 gradually increases from top to bottom, as the positioning cavity 402 moves upward, the diameter of the inner wall at the point where the positioning cavity 402 and the clamping member 4032 abut against each other increases. The clamping member 4032 moves in a direction away from the axis of the water-stirring member 200 under the squeezing of the insert 401. At this time, the insert 401 can continue to be inserted.

[0165] As the insert 401 is inserted, when the clamping piece 4032 enters the limiting groove, the positioning cavity 402 moves downward, and the end of the clamping piece 4032 close to the axis of the water-stirring member 200 abuts against the bottom of the limiting groove, and the end of the clamping piece 4032 away from the axis of the water-stirring member 200 abuts against the inner wall of the positioning cavity 402, thereby realizing axial positioning of the insert 401.

The driving portion 404 is disposed on the side wall of the assembly portion 210 - 1 , and the driven portion 405 is disposed on the positioning cavity 402 and cooperates with the driving portion 404 in transmission.

[0167] Specifically, the driven part 405 includes a hollow limiting column 4051 disposed on the positioning cavity 402 and an extension plate 4052 extending radially from the outer wall of the hollow limiting column 4051 in the direction away from the axis of the water stirring member 200. The hollow limiting column 4051 extends upward from the top of the positioning cavity 402 and is connected to the positioning cavity 402 as a whole. The inner diameter of the hollow limiting column 4051 is adapted to the diameter of the insert 401. The extension plate 4052 abuts against the driving part 404 through an inclined surface inclined from top to bottom in the direction close to the axis of the water stirring member 200. When the driving part 404 moves in the direction close to the axis of the water stirring member 200, the driving part 404 squeezes the end of the extension plate 4052 to push the positioning cavity 402 to move upward.

Since the diameter of the positioning cavity 402 gradually increases from bottom to top, the insert 401 pushes the limiter 403 to move upward while pushing the limiter 403 to move in the direction away from the axis of the water stirring member 200, so that the insert 401 can smoothly enter the limiter 403. With the insertion of the insert 401, when the clamping member 4032 enters the limiting groove, the limiter 403 moves downward, and the end of the clamping member 4032 close to the axis of the water stirring member 200 abuts against the bottom of the limiting groove, and the end of the clamping member 4032 away from the axis of the water stirring member 200 abuts against the inner wall of the positioning cavity 402, so as to realize the axial positioning of the insert 401.

[0190] Embodiment 3

[0193] 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.

[0194] 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.

When the water stirring member 200 is disassembled, the unlocking assembly is operated to make the locking assembly release the lock on the insert 401, so that the water stirring member 200 can be detached from the upper end of the stirring shaft 300.

[0227] The water stirring member 200 and the stirring shaft 300 are axially positioned by a screw 210-7.

[0228] In this embodiment, the setting of the water seal structure 500 can, on the one hand, prevent washing water from entering the gap between the water stirring component 200 and the bottom of the barrel, and on the other hand, can also prevent washing water from entering the connection between the water stirring component 200 and the stirring shaft 300, so that the interior of the water stirring component 200 remains dry.

[0229] In this embodiment, a sealing groove 210 - 4 is provided at the top of the water stirring member 200 , and a sealing cover 210 - 5 for sealing the upper end of the water stirring member 200 is provided at the sealing groove 210 - 4 to prevent washing water from entering the interior of the water stirring member 200 .

[0230] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion.

The inserting portion is inserted into the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0231] The top of the flat plate portion and the top of the water stirring member 200 are in the same plane.

[0232] The sealing groove 210-4 includes a first section and a second section with increasing diameters from top to bottom.

[0234] In this embodiment, a sealing ridge extending along the circumference of the plug-in portion is provided in the middle of the plug-in portion, and the plug-in 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 along the circumference of the plug-in portion and is provided with multiple circles arranged at intervals along the axial direction of the plug-in portion.

[0235] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring member 200 to improve the smoothness of the insertion of the sealing cover 210 - 5 .

[0236] Preferably, in this embodiment, the water stirring member 200 has a maximum radius along the radial direction of the washing tub 100 at a certain distance from the bottom surface of the washing tub 100, and a guide surface extending toward the periphery is formed there, for guiding the clothes below thereto move toward the periphery along the guide surface during washing.

[0237] Embodiment 4

[0238] like Fig.15 and Fig.16 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.

[0239] It should be noted that, in the embodiment of the present invention, the maximum radius of the water-stirring member 200 refers to the maximum radius of the horizontal cross-section of the water-stirring member 200, and the radius of the horizontal cross-section of the water-stirring member 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 member 200 taken along the horizontal direction.

[0240] 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.

[0241] 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.

[0242] 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.

[0243] 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.

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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.

[0248] 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 .

[0249] In the preferred embodiment of this embodiment, Fig.16 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.

[0250] 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.

[0251] 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.

[0252] 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.

[0253] 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.

[0254] 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.

[0255] 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.

[0256] 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.

[0257] 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.

[0258] 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.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.
