Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to a pulsator assembly and clothing processing equipment. Background Art

[0002] As people's demands for higher quality of life at home increase, the demand for efficient, multifunctional household appliances is also growing. Traditional pulsator washing machines are simple to operate, relying on friction between the clothes and between the clothes and the drum wall to clean them. However, they are not very effective when handling clothes that require special treatment, such as wool and silk. Agitator washing machines rely primarily on the rotation of the agitator to effectively tumble and rub the clothes in the water to clean them. While they can achieve good cleaning results for wool and silk, agitator washing machines do not achieve good cleaning results when handling clothes that require more intensive cleaning, such as denim and cotton. To address this issue, the main method currently used is to equip the washing machine with a detachable agitator and combine it with the pulsator washing machine, allowing users to switch between agitator and pulsator washing machines at any time according to different clothing types and washing needs, thereby providing a better washing experience.

[0003] In the related art, the locking between the agitator and the impeller is achieved by relying on the locking structure on the agitator to achieve a detachable connection with the impeller. When the locking structure is worn or loose, it is easy to cause the locking effect between the agitator and the impeller to deteriorate, thereby reducing the working reliability of the agitator. Replacing the locking structure requires replacing the entire agitator, thereby increasing maintenance costs. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a pulsator assembly that, when maintenance and replacement of a locking member are required, only the locking rod needs to be replaced, rather than the entire agitator, thereby saving maintenance costs. Moreover, due to the locking member provided between the locking rod and the agitator, the operating reliability of the agitator can be improved.

[0005] The present invention also provides a clothes processing device having the above-mentioned pulsator assembly.

[0006] According to the impeller assembly of the first aspect of the present invention, the impeller assembly includes: an impeller disc, an agitator, a locking rod and a locking member, wherein the agitator has an accommodating cavity; the locking rod is arranged in the accommodating cavity, and the agitator is detachably connected to the impeller disc through the locking rod; the locking member is connected to the locking rod, and the locking rod is connected to the agitator through the locking member.

[0007] According to the impeller assembly of the present invention, the agitator is detachably connected to the impeller disc via a locking rod, which can realize both impeller and stirring washing modes, thereby improving the user's washing experience. Compared with the related art, the locking and unlocking between the agitator and the impeller disc are achieved by relying on the locking structure on the agitator. As a result, when the locking structure is worn, loose and needs to be replaced, the entire agitator must be replaced, resulting in increased maintenance costs. In the present invention, by setting the locking member on the locking rod in the accommodating chamber a, when the locking member needs to be replaced, only the locking rod needs to be replaced without replacing the entire agitator, thereby saving maintenance costs. At the same time, since a locking member is set between the locking rod and the agitator, the problem of the locking effect between the agitator and the impeller disc being weakened due to the loosening of the locking member can be avoided, which can effectively improve the working reliability of the agitator.

[0013] Furthermore, the driving member further includes: an elastic member, which is arranged in the handle, one end of the elastic member is connected to the handle, and the other end of the elastic member is connected to the pressing portion and / or the second locking portion.

[0014] According to some embodiments of the present invention, one of the first locking portion and the second locking portion is configured as a socket, and the other is configured as a retractable pin, which can be selectively extended into the socket to lock the agitator and the locking rod to limit the relative movement of the agitator and the locking rod in the axial direction and / or circumferential direction.

[0015] According to some embodiments of the present invention, a limit plate extending radially away from the axis is provided on the outer periphery of the locking rod, and a limit surface is formed on the inner wall of the accommodating cavity, which is suitable for axially abutting against the side of the limit plate toward the impeller disk.

[0016] Furthermore, the diameter of the accommodating cavity is reduced at one end close to the impeller disk in the axial direction, and defines a limiting step, and the limiting surface is formed on the limiting step.

[0017] In some embodiments, the agitator is provided with a first limiting portion adapted to cooperate with the impeller disc in a circumferential upper limit position, and the locking rod is provided with a second limiting portion adapted to cooperate with the impeller disc in an axial upper limit position.

[0018] Furthermore, a groove open toward the agitator is formed on the impeller disk, and a partition is provided in the groove and spaced from the side wall of the groove to divide the groove into a first cavity and a second cavity adjacent to each other in the radial direction; wherein, a third limiting portion suitable for limiting cooperation with the first limiting portion is formed on the inner wall of the first cavity, and a fourth limiting portion suitable for limiting cooperation with the second limiting portion is formed on the inner wall of the second cavity.

[0019] Furthermore, the first limiting portion is constructed as a plurality of first teeth arranged at the bottom end of the agitator and spaced circumferentially, and the third limiting portion is constructed as a second tooth protruding from the inner wall of the first cavity, and the second tooth is suitable for engaging with the first tooth to limit the circumferential movement of the agitator relative to the impeller.

[0020] In some embodiments, the second limiting portion is arranged on at least a portion of the outer periphery of the locking rod and extends circumferentially, and at least a portion of the fourth limiting portion extends circumferentially along the inner wall of the first cavity; wherein the locking rod has a first position, and in the first position, the second limiting portion and the fourth limiting portion are at least partially overlapped in their axial projections to limit the axial movement of the locking rod relative to the impeller disk.

[0021] Furthermore, the locking lever has a second position where the second limiting portion and the fourth limiting portion are projected and staggered in the axial direction, and the locking lever rotates relative to the impeller disk to switch between the first position and the second position.

By detachably connecting the agitator to the pulsator disc via the locking rod, both pulsator and agitator modes can be achieved, thereby enhancing the user's laundry experience. Furthermore, by disposing the locking member on the locking rod within the receiving chamber a, when the locking member needs to be replaced, only the locking rod needs to be replaced, rather than the entire agitator, thereby reducing maintenance costs. Furthermore, the provision of a locking member between the locking rod and the agitator prevents the locking member from becoming loose, thereby preventing a poor locking effect between the agitator and the pulsator disc, thereby effectively improving the reliability of the agitator. In addition, due to the circumferential limitation between the agitator and the locking rod and the impeller, which is achieved through the cooperation between the first limiting part on the agitator and the impeller, in the agitation washing mode, the agitator is the main component for transmitting washing force. The agitator is located on the outer periphery of the locking rod, has a larger diameter, and has higher structural strength and rigidity, which is beneficial to improving the service life of the agitator and the locking rod, and can improve the working reliability of the agitator and the locking rod.

[0054] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0055] Reference below Figures 1-8 A pulsator assembly 1 and a clothes treating apparatus according to an embodiment of the present invention are described.

[0056] like Figure 1 As shown, according to the pulsator assembly 1 of the first embodiment of the present invention, the pulsator assembly 1 includes: a pulsator disk 11, a stirrer 12, a locking rod 13 and a locking member.

[0057] Among them, the agitator 12 has a accommodating cavity 12a; the locking rod 13 is arranged in the accommodating cavity 12a, and the agitator 12 is detachably connected to the impeller 11 through the locking rod 13; the locking piece is connected to the locking rod 13, and the locking rod 13 is connected to the agitator 12 through the locking piece.

[0058] Specifically, the pulsator 11 can be set in the clothing processing device and can rotate in the clothing processing device. When the clothing processing device is working, the pulsator 11 can rotate continuously to rub against the clothes to be cleaned, and by generating a stirring effect in the water, the clothes to be cleaned are fully in contact with the detergent, thereby achieving a good clothing washing effect; the locking rod 13 can be accommodated in the accommodating cavity 12a of the agitator 12, and the agitator 12 is detachably connected to the pulsator 11 through the locking rod 13. When the locking member locks the agitator 12 and the locking rod 13, and the agitator 12 is set on the pulsator 11, the rotation of the pulsator 11 can drive the agitator 12 to rotate, corresponding to the stirring washing mode; when the user selects the pulsator washing mode, the locking member can unlock the agitator 12 and the locking rod 13, so that the agitator 12 and the locking rod 13 can be easily removed from the pulsator 11 to meet the requirements of the pulsator washing mode.

[0059] According to the pulsator assembly 1 of the present invention, the agitator 12 is detachably connected to the pulsator disc 11 via the locking rod 13, which can realize both the pulsator and stirring washing modes, thereby improving the user's washing experience. Compared with the related art, the locking and unlocking between the agitator 12 and the pulsator disc 11 are realized by relying on the locking structure on the agitator 12, resulting in that when the locking structure is worn, loose and needs to be replaced, the entire agitator 12 must be replaced, resulting in increased maintenance costs. In the present invention, by setting the locking member on the locking rod 13 in the accommodating cavity 12a, when the locking member needs to be replaced, only the locking rod 13 needs to be replaced without replacing the entire agitator 12, thereby saving maintenance costs. At the same time, since the locking member 13 is set between the locking rod 13 and the agitator 12, the problem of the locking effect between the agitator 12 and the pulsator disc 11 being deteriorated due to the loosening of the locking member 13 can be avoided, which can effectively improve the working reliability of the agitator 12.

[0060] like Figure 1 As shown, according to some embodiments of the present invention, the locking member is arranged at one end of the locking rod 13 away from the impeller 11, and the locking member includes a first locking portion 14 and a second locking portion 15. The first locking portion 14 is arranged on the agitator 12, and the second locking portion 15 is arranged on the locking rod 13.

[0061] Specifically, the locking member can be provided at an end of the locking rod 13 away from the pulsator disk 11, so that there is sufficient space for the locking rod 13 to perform locking and unlocking operations without interfering with the connection between the locking rod 13 and the pulsator disk 12. The first locking portion 14 and the second locking portion 15 are provided on the agitator 12 and the locking rod 13, respectively. Through the cooperation of the first locking portion 14 and the second locking portion 15, the agitator 12 and the locking rod 13 can be quickly locked or unlocked to complete the installation or removal of the agitator 12, thereby switching between the pulsator washing mode and the agitator washing mode to fully meet different washing needs.

[0062] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the locking member further includes: a locking shell 16, the locking shell 16 is connected to one end of the locking rod 13 and is formed with a limiting end surface 1611 suitable for abutting against one end of the agitator 12, and the second locking portion 15 is movably arranged on the locking shell 16 to selectively protrude from the limiting end surface 1611.

[0063] Specifically, the locking housing 16 can be connected to one end of the locking rod 13 in the axial direction. For example, the locking housing 16 can be connected to the locking rod 13 by a fastener. A limited end surface 1611 is formed on the locking housing 16. The limited end surface 1611 is suitable for abutting against one end of the agitator 12 in the axial direction. The limited end surface 1611 can increase the contact area between the locking housing 16 and the agitator 12, thereby improving the connection stability between the locking rod 13 and the agitator 12; the second locking portion 1 The second locking portion 15 can optionally protrude from the limiting end surface 1611. When the second locking portion 15 protrudes from the limiting end surface 1611, one end of the locking rod 13 in the axial direction can be connected to the agitator 12 for limiting position, and the other end of the locking rod 13 can be connected to the impeller disk 11 for limiting position in the axial direction. This can achieve axial limiting of the locking rod 13 and the agitator 12 as a whole and the impeller disk 11, prevent the locking rod 13 and the agitator 12 from falling out, and effectively improve the installation stability of the agitator 12 and the locking rod 13.

[0064] It should be pointed out that since the second locking portion 15 is arranged on the locking shell 16, and the locking shell 16 can be connected to the locking rod 13 by fasteners, when the second locking portion 15 needs to be maintained and replaced, only the locking shell 16 can be maintained and replaced without replacing the locking rod 13, thereby further saving economic costs.

[0065] like Figure 3 As shown, according to some embodiments of the present invention, the locking member further includes: a driving member 17 movably disposed on the locking housing 16 and adapted to drive the second locking portion 15 to move relative to the locking housing 16 .

[0066] Specifically, the driving member 17 is movably provided on the locking housing 16. By operating the driving member 17 to move relative to the locking housing 16, the driving member 17 can transmit the driving force to the second locking portion 15, so that the second locking portion 15 produces linear motion, that is, the second locking portion 15 is retractable. Therefore, by operating the driving member 17, the second locking portion 15 can be quickly matched with the agitator 12 to correspondingly play a locking or unlocking role, thereby improving the convenience of installation and disassembly of the locking rod 13 and the agitator 12.

[0067] like Figure 1 、 Figure 4 and Figure 6 As shown, according to some embodiments of the present invention, the locking housing 16 includes: a support plate 161 , a first support portion 162 , a second support portion 163 and a handle 164 .

[0068] Among them, a limited end surface 1611 is set at the bottom of the support plate 161; the first support part 162 and the second support part 163 are arranged on the support plate 161 and a receiving cavity suitable for accommodating the second locking part 15 is formed inside; the handle 164 is connected between the first support part 162 and the second support part 163 and is separated from the support plate 161 to form a handle space 164a.

[0069] Specifically, at least a portion of the support plate 161 can be connected to one end of the locking rod 13 in the axial direction, and the bottom of the support plate 161 (the side of the support plate 161 facing the locking rod 13 in the thickness direction) forms a limited end surface 1611. The support plate 161 can support and fix some other components of the locking housing 16 (such as the handle 164), the driving member 17 and the second locking portion 15, so as to ensure the normal operation of the driving member 17 and the second locking portion 15; the first support portion 162 and the second support portion 16 The first support portion 162 and the second support portion 163 may be provided on a side of the support plate 161 that is away from the locking rod 13 in the thickness direction. The receiving cavities inside the first support portion 162 and the second support portion 163 are suitable for receiving the second locking portion 15, thereby providing sufficient installation space for the second locking portion 15. The handle 164 may be connected to the first support portion 162 and the second support portion 163 at both ends in the extension direction, respectively. The handle 164 is spaced apart from the support plate 161 in the axial direction to form a handle space 164a for the user to hold the locking rod 13.

[0070] Furthermore, in some specific embodiments of the present invention, a through hole is formed on the support plate 161 , the receiving cavity is communicated with the through hole, and the second locking portion 15 can selectively extend out of the receiving cavity to protrude from the limiting end surface 1611 .

[0071] like Figure 3 As shown, according to some embodiments of the present invention, the driving member 17 includes: a pressing portion 171, the pressing portion 171 is connected to the second locking portion 15 and is movably arranged on the side of the handle 164 facing the support plate 161, and the pressing portion 171 drives the second locking portion 15 to move relative to the locking shell 16.

[0072] Specifically, the pressing portion 171 is movably disposed on the side of the handle 164 facing the support plate 161, so that the pressing portion 171 is accommodated in the handle space 164a, which can improve the convenience and comfort of the user when pressing the pressing portion 171. The pressing portion 171 is connected to the second locking portion 15. When the user presses the pressing portion 171, the pressing portion 171 can drive the second locking portion 15 to move relative to the locking housing 16, facilitating the installation or removal of the locking lever 13. For example, during the installation of the locking rod 13, the pressing portion 171 can be pressed to drive the second locking portion 15 to move axially away from the agitator 12, so that the second locking portion 15 moves to a state where it is completely accommodated in the accommodating cavity, thereby ensuring a normal position-limited connection between the locking rod 13 and the pulsator disk 11. After the locking rod 13 is connected to the pulsator disk 11, the pressing portion 171 can be released, and the pressing portion 171 can drive the second locking portion 15 to move axially closer to the agitator 12 to a position where the locking rod 13 is locked with the agitator 12. When it is necessary to switch to the washing mode, the pressing portion 171 can be pressed to move the second locking portion 15 to a position away from the agitator 12, thereby unlocking the locking rod 13 and the agitator 12 for disassembly.

[0073] like Figure 3 、 Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the driving member 17 further includes: an elastic member 172, the elastic member 172 is arranged in the handle 164, one end of the elastic member 172 is connected to the handle 164, and the other end of the elastic member 172 is connected to the pressing portion 171 and / or the second locking portion 15.

[0074] Specifically, the arrangement of the elastic member 172 can be that one end of the elastic member 172 is connected to the handle 164, and the other end of the elastic member 172 is connected only to the pressing portion 171, but not to the second locking portion 15. When the pressing portion 171 is pressed, the pressing portion 171 can compress the elastic member 172; the arrangement of the elastic member 172 can also be that one end of the elastic member 172 is connected to the handle 164, and the other end of the elastic member 172 is connected only to the second locking portion 15, but not to the pressing portion 171. When the pressing portion 171 is pressed, the pressing portion 171 can compress the elastic member 172. When the pressing part 171 is pressed, the pressing part 171 can drive the second locking part 15 to move, and the movement of the second locking part 15 can compress the elastic part 172; the arrangement of the elastic part 172 can also be that one end of the elastic part 172 is connected to the handle 164, and the other end of the elastic part 172 is connected to both the pressing part 171 and the second locking part 15. When the pressing part 171 is pressed, the pressing part 171 can drive the second locking part 15 to move, and the pressing part 171 and the second locking part 15 move in the same direction and compress the elastic part 172. By setting the elastic member 172, when the pressing portion 171 is pressed and the second locking portion 15 moves in a direction away from the agitator 12, the elastic member 172 can be compressed under the action of the pressing portion 171 and / or the second locking portion 15, so that when the pressing portion 171 is released, under the restoring force of the elastic member 172, the elastic member 172 can drive the second locking portion 15 to move to a position protruding from the limiting end surface 1611. In this way, the locking automation and locking efficiency between the locking rod 13 and the agitator 12 can be improved, which can further enhance the user experience.

[0075] In addition, in some specific embodiments of the present invention, the other end of the elastic member 172 is connected to both the pressing portion 171 and the second locking portion 15, and the pressing portion 171 and the latch are arranged adjacent to each other in the horizontal direction. In this way, the structural integration of the elastic member 172, the pressing portion 171 and the second locking portion 15 can be improved, which is conducive to saving layout space.

[0076] like Figure 6 As shown, according to some embodiments of the present invention, one of the first locking portion 14 and the second locking portion 15 is configured as a socket, and the other is configured as a retractable pin, which can be selectively extended into the socket to lock the agitator 12 and the locking rod 13 to limit the relative movement of the agitator 12 and the locking rod 13 in the axial direction and / or the circumferential direction.

[0077] Specifically, the first locking portion 14 and the second locking portion 15 can be configured as a mating pin and a socket, wherein the pin can be selectively inserted into the socket to lock the agitator 12 and the locking rod 13, thereby limiting relative axial and / or circumferential movement of the agitator 12 and the locking rod 13. Thus, under the combined action of the pin and the socket, the locking rod 13 can be secured to the agitator 12 and mounted on the impeller 11. When the laundry processing device is in operation, the rotation of the impeller 11 can drive the agitator 12 and the locking rod 13 to rotate synchronously, causing the laundry to tumble and rub effectively in the water, thereby achieving a good agitation washing mode function. Furthermore, by utilizing the mating pin and the socket, the locking rod 13 can be easily and quickly unlocked from the agitator 12 by retracting the pin, thereby improving the convenience and efficiency of disassembling the agitator 12 and the locking rod 13.

[0078] It should be pointed out that when the above-mentioned socket and pin limit the relative movement of the agitator 12 and the locking rod 13 in the axial direction and / or the circumferential direction, the axial limitation between the locking rod 13 and the agitator 12 as a whole and the impeller 11 can be achieved.

[0079] In some specific embodiments of the present invention, the socket can be located on the periphery of the agitator 12, and the pin can be telescopically arranged on the periphery of the locking rod 13. The pin can be selectively inserted into the socket radially to limit the relative movement of the agitator 12 and the locking rod 13 in the circumferential and axial directions.

[0080] In some other specific embodiments of the present invention, the socket and the latch may extend axially, and the latch may be selectively inserted into the socket along the axial direction to limit the relative movement of the agitator 12 and the locking rod 13 in the axial direction.

[0081] like Figure 3-Figure 5 As shown, according to some embodiments of the present invention, a limiting plate 132 extending radially away from the axis is provided on the outer periphery of the locking rod 13, and a limiting surface 122 is formed on the inner wall of the accommodating cavity 12a, and the limiting surface 122 is suitable for axially stopping against the side of the limiting plate 132 toward the impeller disk 11.

[0082] Specifically, the limiting plate 132 can be provided on the outer periphery of the locking rod 13. The limiting plate 132 has a certain thickness in the axial direction and extends radially away from the axis, so that the limiting plate 132 protrudes from the outer periphery of the locking rod 13, and the limiting surface 122 of the inner wall of the accommodating chamber 12a is suitable for cooperating with the limiting plate 132. During the assembly process of the locking rod 13 and the agitator 12, when the locking rod 13 is extended into the accommodating chamber 12a, the limiting surface 122 can abut against the limiting plate 132 in the thickness direction (axial direction) of the limiting plate 132 toward the side of the impeller disc 11, thereby ensuring that the locking rod 13 can be located at a preset position in the accommodating chamber 12a. Therefore, by setting the limiting plate 132 and the limiting surface 122, the locking rod 13 and the agitator 12 can be positioned and limited, which can increase the assembly efficiency, assembly accuracy and reliability between the two. In addition, the limiting surface 122 cooperates with the limiting plate 132 to play a positioning role in the limiting cooperation between the locking rod 13 and the impeller 11, which can further improve the positioning accuracy of the locking rod 13 and the agitator 12 installed as a whole on the impeller 11.

[0083] It should be pointed out that the cooperation between the limiting plate 132 and the limiting surface 122 is only an exemplary illustration. The axial limiting structure between the locking rod 13 and the inner wall of the accommodating cavity 12a in the present invention is not limited to the above-mentioned limiting plate 132 and the limiting surface 122, and the scope of protection is not limited to this. For example, the axial limiting structure between the locking rod 13 and the inner wall of the accommodating cavity 12a can also be other forms of structures such as snap-fit or plug-fit.

[0084] like Figure 1 As shown, according to some embodiments of the present invention, the diameter of the accommodating cavity 12a is reduced at one end close to the impeller disk 11 in the axial direction, and a limiting step is defined, and a limiting surface 122 is formed on the limiting step.

[0085] Specifically, the accommodating chamber 12a may include a first matching chamber and a second matching chamber, the first matching chamber being located at an end of the second matching chamber that is axially closer to the impeller 11, and the diameter of the first matching chamber being smaller than the diameter of the second matching chamber (the axial projection of the second matching chamber covers the axial projection of the first matching chamber), so that the inner wall of the accommodating chamber 12a is at least partially formed as a limiting step, and the limiting surface 122 is formed on the limiting step, so that the limiting surface 122 can cooperate with the limiting plate 132 to play a good positioning and limiting role between the locking rod 13 and the agitator 12.

[0086] like Figure 1 As shown, according to some embodiments of the present invention, the agitator 12 is provided with a first limiting portion 121 suitable for cooperating with the impeller disc 11 in the circumferential upper limit position, and the locking rod 13 is provided with a second limiting portion 131 suitable for cooperating with the impeller disc 11 in the axial upper limit position.

[0087] Specifically, the second limiting portion 131 on the locking rod 13 is axially limited to the pulsator disc 11, while the circumferential limitation between the agitator 12 and the locking rod 13 and the pulsator disc 11 is achieved by the cooperation of the first limiting portion 121 on the agitator 12 and the pulsator disc 11. Therefore, in the agitation washing mode, the agitator 12 is the main component for transmitting the washing force. The agitator 12 is located on the outer periphery of the locking rod 13, has a larger diameter, and has higher structural strength and rigidity, which is conducive to improving the service life of the agitator 12 and the locking rod 13 and can improve the working reliability of the agitator 12 and the locking rod 13. By providing the first limiting portion 121 and the second limiting portion 131, the circumferential and axial limitation between the overall structure of the agitator 12 and the locking rod 13 and the pulsator disc 11 can be achieved, which can ensure that the agitator 12 and the locking rod 13 have good stability and working reliability on the pulsator disc 11.

[0088] like Figure 2 As shown, according to some embodiments of the present invention, a groove 11a open toward the agitator 12 is formed on the impeller disk 11, and a partition 111 is provided in the groove 11a and spaced from the side wall of the groove 11a to separate the groove 11a into a first cavity 11b and a second cavity 11c adjacent to each other in the radial direction; wherein, a third limiting portion 112 suitable for limiting cooperation with the first limiting portion 121 is formed on the inner wall of the first cavity 11b, and a fourth limiting portion 113 suitable for limiting cooperation with the second limiting portion 131 is formed on the inner wall of the second cavity 11c.

[0089] Specifically, the partition 111 is arranged in the groove 11a and separated from the side wall of the groove 11a. The partition 111 has a certain thickness in the radial direction, which can separate the groove 11a into a first cavity 11b and a second cavity 11c adjacent to each other in the radial direction. The first cavity 11b is located on the periphery of the second cavity 11c. The third limiting portion 112 on the inner wall of the first cavity 11b is suitable for cooperating with the first limiting portion 121 to limit the circumferential movement between the impeller 11 and the agitator 12, and the fourth limiting portion 113 on the inner wall of the second cavity 11c is suitable for cooperating with the second limiting portion 131 to limit the axial movement between the impeller 11 and the agitator 12, so that the agitator 12 and the locking rod 13 can be fixed on the impeller 11 through the first limiting portion 121, the second limiting portion 131, the third limiting portion 112 and the fourth limiting portion 113 to ensure that the rotation of the impeller 11 can drive the agitator 12 and the locking rod 13 to rotate, thereby ensuring that the agitator 12 can perform normal stirring work in the agitation washing mode to clean the clothes. In the agitation washing mode, the circumferential limitation between the agitator 12 and the locking rod 13 and the impeller 11 is achieved by the cooperation between the first limiting part 121 on the agitator 12 and the third limiting part 112 on the impeller 11. During the agitation process, the force of the impeller 11 to drive the locking rod 13 and the agitator 12 to rotate is transmitted by the agitator 12 located on the outer periphery of the locking rod 13, which can effectively improve the working reliability and life of the agitator 12 and the locking rod 13.

[0090] like Figure 2 As shown, according to some embodiments of the present invention, the first limiting portion 121 is constructed as a plurality of first teeth arranged at the bottom end of the agitator 12 and spaced circumferentially, and the third limiting portion 112 is constructed as a second tooth protruding from the inner wall of the first cavity 11b, and the second tooth is suitable for engaging with the first tooth to limit the circumferential movement of the agitator 12 relative to the impeller 11.

[0091] Specifically, a plurality of first teeth can be provided at the bottom end of the agitator 12, and the agitator 12 can be assembled with the impeller disk 11 along the axial direction. During assembly, the first teeth are adapted to mesh with the second teeth, so that the second teeth can block the circumferential movement of the first teeth, thereby limiting the circumferential movement of the agitator 12 relative to the impeller disk 11. By meshing the first teeth with the second teeth to limit the circumferential position, on the one hand, the stability and reliability of the connection between the agitator 12 and the impeller disk 11 can be improved, which helps to improve the working performance and safety of the agitator 12; on the other hand, the meshing of the plurality of first teeth with the plurality of second teeth allows the load to be evenly distributed between the first teeth and the second teeth, thereby avoiding local load concentration, effectively extending the service life of the agitator 12 and the impeller disk 11, and saving maintenance costs.

[0092] like Figure 4As shown, according to some embodiments of the present invention, the second limiting portion 131 is arranged on at least a portion of the outer periphery of the locking rod 13 and extends circumferentially, and at least a portion of the fourth limiting portion 113 extends circumferentially along the inner wall of the first cavity 11b; wherein, the locking rod 13 has a first position, and in the first position, the second limiting portion 131 and the fourth limiting portion 113 are at least partially overlapped in the axial projection, so as to limit the axial movement of the locking rod 13 relative to the impeller 11.

[0093] Specifically, the second limiting portion 131 can be provided at the other end of the locking rod 13. The second limiting portion 131 can protrude from at least a portion of the outer circumferential surface of the locking rod 13, and at least a portion of the second limiting portion 131 can extend circumferentially. At least a portion of the fourth limiting portion 113 can extend circumferentially along the inner wall of the first cavity 11b. In the first position, the second limiting portion 131 can at least partially overlap with the axial projection of the fourth limiting portion 113 to limit the axial movement of the locking rod 13 relative to the impeller disk 11. Under the action of the first locking portion 14 and the second locking portion 15, the locking rod 13 is fixedly connected to the agitator 12. Therefore, in the first position, the axial movement of the locking rod 13 and the agitator 12 as a whole relative to the impeller disk 11 is limited, thereby optimizing the anti-slip performance of the agitator 12 and the locking rod 13 and improving the working reliability and stability of the agitator 12 and the locking rod 13.

[0094] In addition, in some other specific embodiments of the present invention, the second limiting portion 131 is constructed as a plurality of portions arranged at intervals in the circumferential direction of the locking rod 13, and the fourth limiting portion 113 is constructed as a plurality of portions corresponding one to one to the second limiting portion 131. By increasing the number of the second limiting portion 131 and the fourth limiting portion 113, the anti-slip performance of the agitator 12 and the locking rod 13 can be further optimized.

[0095] like Figure 4 As shown, according to some embodiments of the present invention, the locking rod 13 has a second position where the second limiting portion 131 and the fourth limiting portion 113 are projected axially offset, and the locking rod 13 rotates relative to the impeller 11 to switch between the first position and the second position.

[0096] Specifically, in the second position, the axial projections of the second limiting portion 131 and the fourth limiting portion 113 are offset. At this point, the axial restraint between the locking lever 13 and the pulsator disk 11 is released, allowing the locking lever 13 and the agitator 12 to be removed from the pulsator disk 11, thereby switching to the pulsator washing mode. The locking lever 13 can rotate relative to the pulsator disk 11 to switch between the first and second positions, corresponding to the engagement or release of the second limiting portion 131 and the fourth limiting portion 113, to facilitate installation or removal of the locking lever 13 and the agitator 12. By rotating the locking lever 13, the user can simply rotate the locking lever 13 to engage or disengage the axial restraint between the locking lever 13 and the pulsator disk 11 without the need for additional tools or complex steps, thereby improving the efficiency and convenience of installing and removing the locking lever 13 and the agitator 12.

[0097] like Figure 2 As shown, according to some embodiments of the present invention, the fourth limiting portion 113 includes: a first section 1131 and a second section 1132 .

[0098] The first section 1131 extends along the circumferential direction, and the second section 1132 extends along the axial direction, and is suitable for abutting against the free end of the second limiting portion 131 in the circumferential direction at the first position.

[0099] Specifically, the first section 1131 and the second section 1132 can both protrude from the inner wall of the second cavity 11c, the first section 1131 extends circumferentially on the inner wall of the second cavity 11c, the first section 1131 and the second limiting portion 131 are at least partially overlapped in the axial projection, and the side of the first section 1131 axially away from the locking rod 13 can be stopped against the side of the second limiting portion 131 axially away from the impeller disk 11 to limit the axial movement of the locking rod 13 relative to the impeller disk 11; the second section 1132 extends axially, and the first section 1131 and the second limiting portion 131 are at least partially overlapped in the axial projection. position, the second section 1132 can abut against the free end of the second limiting portion 131 in the circumferential direction to prevent the second limiting portion 131 from continuing to rotate in one direction (for example, only clockwise or only counterclockwise). In this way, the second limiting portion 131 can be kept in the limited position to ensure the stability of the connection between the locking rod 13 and the impeller 11, and when it is necessary to release the limit between the locking rod 13 and the impeller 11, the second limiting portion 131 can smoothly rotate in the direction away from the second section 1132 to quickly release the limit.

[0100] In addition, in some specific embodiments of the present invention, the first section 1131 and the second section 1132 are connected, and an arc-shaped transition section is formed between the first section 1131 and the second section 1132. The arc-shaped transition section has a smooth surface, which is beneficial to protecting the second limiting portion 131 from damage and extending its service life.

[0101] like Figure 6 As shown, according to some embodiments of the present invention, a fitting hole 12b is formed at the top end of the stirrer 12, and the latch is adapted to extend into the fitting hole 12b at the second position.

[0102] Specifically, the latch can be inserted into the matching hole 12b when the locking rod 13 is in the second position to connect the locking rod 13 to the agitator 12. In the second position, the axial restraint between the locking rod 13 and the impeller disk 11 is released. By further releasing the restraint between the agitator 12 and the impeller disk 11, the agitator 12 and the locking rod 13 can be removed. Therefore, by using the latch to engage with the matching hole 12b to connect the agitator 12 and the locking rod 13, the agitator 12 and the locking rod 13 can be removed from the impeller disk 11 as a whole, thereby improving disassembly efficiency and enhancing the user experience.

[0103] In addition, in some specific embodiments of the present invention, the matching hole 12b and the insertion hole are arranged at intervals in the circumferential direction. In this way, it can be ensured that the locking rod 13 rotates and switches between the first position and the second position, and the pin can be correspondingly inserted into the insertion hole or the matching hole 12b for installation or disassembly.

[0104] like Figures 1-8 As shown, according to the clothing processing device of the second embodiment of the present invention, the clothing processing device includes: the pulsator assembly 1 described in any one of the above embodiments, and the technical effects produced are consistent with those in the above embodiments, which will not be repeated here.

[0105] In summary, the pulsator assembly 1 according to the present invention includes: a pulsator disc 11, an agitator 12, a locking rod 13, and a locking member. The locking rod 13 is disposed within the accommodating cavity 12a of the agitator 12. The agitator 12 is detachably connected to the pulsator disc 11 via the locking rod 13. The agitator 12 is provided with a first limiter 121 adapted to engage with the pulsator disc 11 in the circumferential upper limit position. The locking rod 13 is provided with a second limiter 131 adapted to engage with the pulsator disc 11 in the axial upper limit position. The locking rod 23 is connected to the agitator 12 via the locking member. By arranging for the agitator 12 to be detachably connected to the pulsator disc 11 via the locking rod 13, both pulsator and agitator washing modes can be achieved, thereby enhancing the user's washing experience. Furthermore, by arranging the locking member on the locking rod 13 within the accommodating chamber 12a, when the locking member needs to be replaced, only the locking rod 13 needs to be replaced without replacing the entire agitator 12, thereby saving maintenance costs. Furthermore, since the locking member 13 is disposed between the locking rod 13 and the agitator 12, the problem of the locking member 13 becoming loose, which may lead to a deterioration in the locking effect between the agitator 12 and the impeller 11, can be avoided, thereby effectively improving the reliability of the agitator. Furthermore, since the circumferential limit between the agitator 12, the locking rod 13, and the impeller 11 is achieved by the first limiter 121 on the agitator 12 cooperating with the impeller 11, in the agitation washing mode, the agitator 12 is the main component for transmitting the washing force. The agitator 12 is located on the outer periphery of the locking rod 13, has a larger diameter, and has higher structural strength and rigidity, thereby facilitating the extension of the service life of the agitator 12 and the locking rod 13, thereby improving the reliability of the agitator 12 and the locking rod 13.
