[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0031] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not.

[0032] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0033] The embodiment of the present invention provides a pulsator assembly and a clothing processing device. The pulsator assembly described in the embodiment of the present invention can be applied to a stirring type washing machine and a pulsator type washing machine. When the pulsator and the stirring rod are installed, it is a stirring type washing machine; when the pulsator and the stirring rod are removed, it is a pulsator type washing machine. A connecting structure and a positioning structure are provided on both the pulsator and the stirring rod; the connecting structure allows the relative movement between the pulsator and the stirring rod in the radial direction to connect and disconnect, and the positioning structure limits the radial position of the pulsator and the stirring rod in the connected state. The double limiting of the connecting structure and the positioning structure makes the connection between the pulsator and the stirring rod more stable, thereby improving the connection reliability of the pulsator and the stirring rod. It can be understood that the washing machine includes a single-wash washing machine with a separate washing function, a washing machine with a washing and dehydrating function, and a washing-drying machine with a washing and drying function.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a pulsator assembly 10, which includes a pulsator 1 and a stirring rod 2. The pulsator 1 can rotate around the axis; the stirring rod 2 is detachably connected to the pulsator 1 coaxially, that is, the stirring rod 2 is coaxially arranged with the pulsator 1, and the stirring rod 2 is detachably connected to the pulsator 1. When the pulsator 1 is connected to the stirring rod 2, the pulsator 1 can rotate around the axis, and can drive the stirring rod 2 to rotate around the axis together. Several stirring wings are also provided on the side wall of the stirring rod 2, which can rotate back and forth within 360° according to different clothing textures, dirtiness, and the quality of the laundry, etc., and the clothes can be held in the arms and rubbed back and forth to thoroughly remove the stains.

[0035] like Figure 1 and Figure 2 As shown, a connecting structure 3 and a positioning structure 4 are provided on the impeller 1 and the stirring rod 2 to realize a detachable connection between the impeller 1 and the stirring rod 2; the connecting structure 3 allows radial relative movement between the impeller 1 and the stirring rod 2 to connect and disconnect. It can be understood that the connecting structure 3 allows radial relative movement between the impeller 1 and the stirring rod 2. For example, when the connecting structure 3 of the impeller 1 and the connecting structure 3 of the stirring rod 2 move relative to each other in the radial direction until they have an overlapping part, the impeller 1 is connected to the stirring rod 2; when the connecting structure 3 of the impeller 1 and the connecting structure 3 of the stirring rod 2 move relative to each other in the radial direction until there is no overlapping part, the impeller 1 is disconnected from the stirring rod 2. The positioning structure 4 limits the radial position of the impeller 1 and the stirring rod 2 in the connected state. It can be understood that when the impeller 1 and the stirring rod 2 are in the connected state, the impeller 1 and the stirring rod 2 can still move relative to each other in the radial direction to disconnect, and the positioning structure 4 can limit the relative movement of the impeller 1 and the stirring rod 2 in the radial direction, thereby limiting the radial position of the impeller 1 and the stirring rod 2 in the connected state, so that the connection between the impeller 1 and the stirring rod 2 can be more stable and not easy to produce relative movement in the radial direction.

[0036] The stirring rod and the impeller in the embodiment of the present invention are detachably coaxially connected, so that the user can remove or install the stirring rod on the impeller according to actual washing needs; the impeller and the stirring rod are provided with a connecting structure and a positioning structure, so that the connecting structure and the positioning structure can double-limit the connection between the impeller and the stirring rod and disperse the resistance; through the connecting structure and the positioning structure, that is, the connecting structure allows the radial relative movement between the impeller and the stirring rod to connect and disconnect, so that under the limitation of the connecting structure, the impeller and the stirring rod can be connected with radial relative movement, and the positioning structure limits the radial position of the impeller and the stirring rod in the connected state, so that the stirring rod and the impeller are not easy to produce relative movement, the connection between the stirring rod and the impeller can be more stable, and the connection reliability of the impeller and the stirring rod is improved.

[0037] In some embodiments, Figure 1 and Figure 2 As shown, the connection structure 3 includes a mortise and tenon structure 31 provided at one axial end of the stirring rod 2 and at one axial end of the impeller 1, so that the mortise and tenon structure 31 provided at one axial end of the stirring rod 2 and the mortise and tenon structure 31 provided at one axial end of the impeller 1 can be connected and disconnected, and the mortise and tenon structure 31 is located in the middle area of ​​the impeller 1, so that the stirring rod 2 is connected to the middle area of ​​the impeller 1 through the mortise and tenon structure 31. When used in a clothing processing device, the stirring rod 2 is located in the middle area of ​​the barrel, so that when washing clothes, the friction force between the clothes in the barrel and the stirring rod 2 is relatively uniform. The mortise and tenon structure 31 corresponds to the radial direction that passes through the stirring rod 2 and the impeller 1, that is, the mortise and tenon structure 31 corresponds to the radial direction that passes through the overall structure formed by the stirring rod 2 and the impeller 1, for example, the mortise and tenon structure 31 of the stirring rod 2 radially passes through the mortise and tenon structure 31 of the impeller 1; or, the mortise and tenon structure 31 of the impeller 1 radially passes through the mortise and tenon structure 31 of the stirring rod 2, so as to realize the relative movement between the impeller 1 and the stirring rod 2 in the radial direction. Combined with Figure 3 and Figure 4 As shown, the positioning structure 4 includes a positioning pin 41 and a positioning hole 42. The positioning pin 41 and the positioning hole 42 are arranged outside the mortise and tenon structure 31. The positioning pin 41 can be inserted into the positioning hole 42, thereby limiting the radial position of the impeller 1 and the stirring rod 2 in the connected state.

[0038] The mortise and tenon structure connection is a concave-convex combination of two components. The protruding part is called the tenon (or tenon head); the concave part is called the mortise (or mortise, tenon groove, groove), and the tenon and the mortise bite together to play a connecting role. The mortise and tenon structure is a combination of the tenon (tenon head) and the mortise (groove). It is an ingenious combination of more and less, high and low, long and short between components, which can effectively limit the twisting of wooden parts in all directions. The most basic mortise and tenon structure consists of two components, one of which has the tenon inserted into the mortise of the other, so that the two components are connected and fixed. The part of the tenon that extends into the mortise is called the tenon tongue, and the rest is called the tenon shoulder.

[0039] The connection structure of the embodiment of the present invention includes a mortise and tenon structure arranged at one axial end of the stirring rod and at one axial end of the impeller, and the mortise and tenon structure corresponds to a radial direction that passes through the stirring rod and the impeller, so that the impeller and the stirring rod can move relative to each other in the radial direction to achieve connection and disconnection between the impeller and the stirring rod; the positioning structure includes a positioning pin and a positioning hole, that is, the positioning pin can be inserted into the positioning hole, so as to limit the radial position of the impeller and the stirring rod in the connected state, so that the stirring rod and the impeller are not prone to relative movement, the connection between the stirring rod and the impeller can be more stable, and the connection reliability between the impeller and the stirring rod is improved.

[0040] In some embodiments, Figure 4 and Figure 5 As shown, the stirring rod 2 includes a body 21, a first telescopic rod 23 and a tenon 25. The body 21 has a cavity 22; the first telescopic rod 23 is located in the cavity 22, the first telescopic rod 23 is coaxially arranged with the body 21, and the first telescopic rod 23 can produce relative translation with the body 21 along the axial direction; the positioning pin 41 is connected to the first telescopic rod 23, so the positioning pin 41 can produce relative translation with the body 21 along the axial direction together with the first telescopic rod 23; the positioning pin 41 protrudes from the first end 24 of the body 21 in the axial direction, and the first end 24 refers to the end of the body 21 close to the impeller 1 in the axial direction; the tenon 25 is used to connect with the groove 11 opened on the impeller 1 to form a connection of the tenon and mortise structure 31, that is, the tenon 25 slides into the groove 11 in the radial direction, thereby connecting to the connection of the tenon and mortise structure 31; the tenon 25 is axially protruding from the first end 24 of the body 21, and the tenon 25 extends from one radial end of the body 21 to the other end, and the positioning pin 41 is located on the radial outer side of the tenon 25.

[0041] The stirring rod of the embodiment of the present invention includes a main body, a first telescopic rod and a tenon. The first telescopic rod can produce relative translation with the main body along the axial direction. The positioning pin is connected to the first telescopic rod, so the positioning pin can produce relative translation with the main body along the axial direction together with the first telescopic rod. The tenon is used to connect with the groove provided on the impeller to form a mortise and tenon structure; for example, when removing the stirring rod from the impeller, first remove the radial position limitation of the impeller and the stirring rod in the connected state by the positioning pin, and then remove the mortise and tenon structure; when installing the stirring rod on the impeller, first pull the first telescopic rod in the direction away from the impeller to drive the positioning pin to move in the direction away from the impeller, so that the positioning pin does not interfere with the radial sliding of the tenon. After the mortise and tenon structure is connected in place, release the first telescopic rod to insert the positioning pin into the positioning hole to limit the radial position of the impeller and the stirring rod in the connected state, and then install it in place at the same time. Therefore, when removing the stirring rod from the impeller or installing the stirring rod on the impeller, the first telescopic rod can be pulled away from the impeller to drive the positioning pin to move away from the impeller, thereby avoiding interference of the positioning pin with the connection and disassembly of the mortise and tenon structure.

[0042] In some embodiments, Figure 2 and Figure 4 As shown, the tenon 25 includes a trapezoidal portion 26, one axial end of the trapezoidal portion 26 is the end of the tenon 25 away from the body 21, and the other axial end of the trapezoidal portion 26 is the end of the tenon 25 connected to the body 21; the cross-sectional area of ​​the trapezoidal portion 26 decreases from one end to the other axial end, and correspondingly, the cross-sectional area of ​​the groove 11 opened on the impeller 1 increases from the end close to the stirring rod 2 to the other end away from the stirring rod 2 in the axial direction, so that when the tenon 25 is connected to the groove 11 opened on the impeller 1 to form a connection of the mortise and tenon structure 31, that is, after the tenon 25 slides into the groove 11 radially and cooperates with the groove 11, the tenon 25 is not easy to move axially and disengage. Specifically, when the tenon 25 moves along the direction of the opening end of the axial groove 11, since the cross-sectional area of ​​the groove 11 gradually decreases as it approaches the opening end, the groove 11 causes axial movement restriction on the portion of the tenon 25 with a relatively larger cross-sectional area, so that the tenon 25 cannot move axially and is confined in the groove 11. Furthermore, after the tenon 25 slides into the groove 11 in the radial direction and cooperates with the groove 11 , the stirring rod 2 and the impeller 1 are connected by the mortise and tenon structure 31 and are also difficult to rotate in the circumferential direction.

[0043] The tenon of the embodiment of the present invention includes a trapezoidal portion, and the cross-sectional area of ​​the trapezoidal portion decreases from one end to the other end in the axial direction. Correspondingly, the cross-sectional area of ​​the groove opened on the impeller increases from one end close to the stirring rod to the other end away from the stirring rod in the axial direction. Therefore, when the tenon moves along the axial direction of the opening end of the groove, the cross-sectional area of ​​the groove gradually decreases as it approaches the opening end, and the groove restricts the axial movement of the portion of the tenon with a relatively larger cross-sectional area, so that the tenon cannot move axially and is confined in the groove, thereby restricting the stirring rod and the impeller in the axial direction.

[0044] In some embodiments, Figure 2 and Figure 3 As shown, one end of the groove 11 in the axial direction is the open end of the groove 11 close to the body 21; the cross-sectional area of ​​the groove 11 increases from the open end to the closed end in the axial direction. That is to say, the cross-sectional area of ​​the groove 11 in the axial direction is smaller at the open end, and the cross-sectional area of ​​the closed end in the axial direction is larger, so that when the tenon 25 is connected with the groove 11 opened on the impeller 1 to form a connection of the mortise and tenon structure 31, that is, after the tenon 25 slides into the groove 11 in the radial direction and cooperates with the groove 11, the tenon 25 is not easy to move in the axial direction and disengage. Specifically, when the tenon 25 moves in the direction of the open end of the axial groove 11, since the cross-sectional area of ​​the groove 11 gradually decreases as it approaches the open end, the groove 11 causes an axial movement restriction on the portion of the tenon 25 with a relatively larger cross-sectional area, so that the tenon 25 cannot move in the axial direction and is confined in the groove 11.

[0045] In some embodiments, Figure 2 and Figure 4As shown, the first telescopic rod 23 includes a handle 231 and a rod body 232. A telescopic first elastic member 27 is disposed between the handle 231 and the body 21 in the axial direction. For example, the first elastic member 27 may be a spring, etc. The rod body 232 is coaxially disposed with the handle 231 and connected to a side of the handle 231 away from the first elastic member 27. The end of the rod body 232 away from the handle 231 is connected to the positioning pin 41. Among them, when the stirring rod 2 is connected to the impeller 1, the initial state of the first elastic member 27 is a compressed state, and the first elastic member 27 presses the first telescopic rod 23 so that the positioning pin 41 is stably inserted into the positioning hole 42 to limit the radial position of the impeller 1 and the stirring rod 2 in the connected state, so that the stirring rod 2 and the impeller 1 are stably connected; when the stirring rod 2 is removed from the impeller 1 or the stirring rod 2 is installed on the impeller 1, the first telescopic rod 23 can be pulled in the direction away from the impeller 1 to drive the positioning pin 41 to move in the direction away from the impeller 1, and the first elastic member 27 is further compressed at this time. When the mortise and tenon structure 31 is installed or disassembled into place, the first telescopic rod 23 is released, the first elastic member 27 returns to its original state, and presses the first telescopic rod 23 so that the positioning pin 41 is inserted into the positioning hole 42, and the stirring rod 2 is installed in place; or the first telescopic rod 23 is released after the mortise and tenon structure 31 is disassembled, and the disassembly is completed at the same time.

[0046] The first telescopic rod of the embodiment of the present invention includes a handle and a rod body, and a telescopic first elastic member is arranged between the handle and the body in the axial direction. When the stirring rod is connected to the impeller, the first elastic member is initially in a compressed state, and the first elastic member presses the first telescopic rod so that the locating pin is stably inserted into the locating hole, thereby stably connecting the stirring rod and the impeller. When the stirring rod is removed from the impeller or installed on the impeller, the first telescopic rod can be pulled in a direction away from the impeller to drive the locating pin to move in a direction away from the impeller, and the first elastic member is further compressed at this time. When the mortise and tenon structure is installed or disassembled into place, the first telescopic rod is released, the first elastic member returns to its original state, and presses the first telescopic rod so that the locating pin is inserted into the locating hole, and the stirring rod is installed in place. Or the first telescopic rod is released after the mortise and tenon structure is disassembled, and the disassembly is completed at the same time. The pressure of the first elastic member ensures that the stirring rod and the impeller can be stably connected in the axial direction, and when the mortise and tenon structure is installed or removed, the first telescopic rod that is pulled to avoid the locating pin interfering with the connection of the mortise and tenon structure can be restored to its original state under the pressure of the first elastic member, ensuring that the locating pin and the locating hole can also be installed or removed in place.

[0047] In some embodiments, Figure 3As shown, the impeller 1 includes a bottom plate 12 and a connecting protrusion 14. The bottom plate 12 is provided with a plurality of rotary blades 13 along the axial direction, and the plurality of rotary blades 13 are evenly arranged along the circumferential direction. When the impeller 1 rotates, the plurality of rotary blades 13 increase the friction between the clothes and the impeller 1, so that the clothes and the impeller 1 are rubbed to remove dirt and wash. The connecting protrusion 14 is located at the center of the impeller 1, and the connecting protrusion 14 is used to be detachably connected to the stirring rod 2, and the plurality of rotary blades 13 are arranged around the connecting protrusion 14; wherein the connecting protrusion 14 is provided with a groove 11 that passes through the radial direction, and the wall surface of the groove 11 can abut against the wall surface of the tenon 25, thereby limiting the circumferential rotation of the tenon 25 relative to the impeller 1; the connecting protrusion 14 is provided with a positioning hole 42 located outside the groove 11, and the positioning hole 42 includes a plurality of, for example, two, and the two positioning holes 42 are located on both sides of the groove 11.

[0048] The impeller of the embodiment of the present invention includes a bottom plate and a connecting protrusion, and a plurality of rotating blades increase the friction between the clothes and the impeller, so that the clothes and the impeller are rubbed to remove dirt and clean; the connecting protrusion is provided with a radial groove, and the wall surface of the groove can abut against the wall surface of the tenon, so as to limit the circumferential rotation of the tenon relative to the impeller; and the axial movement of the tenon is also limited by itself, and a positioning hole located outside the groove is provided on the connecting protrusion. When the positioning pin is inserted into the positioning hole, the radial movement of the tenon relative to the groove can be limited, so that the stirring rod and the impeller are restricted in the circumferential, axial and radial directions, and the clothes and the stirring rod are rubbed in the water, resulting in the stirring rod being subjected to a larger rotational resistance borne by the mortise and tenon structure, and the mortise and tenon structure has sufficient structural strength, so that the connection between the impeller and the stirring rod is more stable, and in fact the radial force along the extension direction of the groove on the stirring rod is relatively small, so the positioning structure connected by the positioning pin and the positioning hole is sufficient to support the connection between the stirring rod and the impeller.

[0049] In some embodiments, Figure 6 As shown, the impeller 1 further includes a mortise and tenon pin 5, which can fill the groove 11 and be detachably connected to the connecting protrusion 14. The mortise and tenon pin 5 allows the relative movement between the impeller 1 and the stirring rod 2 in the radial direction to connect and disconnect, and the mortise and tenon pin 5 limits the relative movement between the impeller 1 and the stirring rod 2 in the radial direction, thereby limiting the radial position of the impeller 1 and the stirring rod 2 in the connected state. The impeller of the embodiment of the present invention further includes a mortise and tenon pin, which can fill the groove and be detachably connected to the connecting protrusion, so that the gap generated on the impeller after the stirring rod is removed can be removably inserted by the mortise and tenon pin to prevent clothes from being entangled in the gap.

[0050] In some embodiments, Figure 6 and Figure 7 As shown, the mortise and tenon pin 5 includes a pin body 51, a second telescopic rod 52 and a second elastic member 53. The appearance of the mortise and tenon pin 5 is similar to the structure of the tenon. Figure 3 and Figure 8As shown, the pin body 51 has an axial through hole 54, and the side wall of the pin body 51 can abut against the groove 11, thereby limiting the circumferential rotation of the pin body relative to the impeller, so that the pin body can stably move radially relative to the impeller; the second telescopic rod 52 passes through the through hole 54 and can move axially; the second elastic member 53 is sleeved outside the second telescopic rod 52 and is located in the through hole 54, and the two ends of the second elastic member 53 abut against the pin body 51 and the second telescopic rod 52 respectively, and the second elastic member 53 is in a compressed state in the initial state, and presses the pin body 51 and the second telescopic rod 52 to be in the initial position, when the second telescopic rod 52 moves axially, it drives the second elastic member 53 to move and be further compressed, and when the second telescopic rod 52 is released, the second elastic member 53 recovers and drives the second telescopic rod 52 to recover to the initial state together. When the pin body 51 and the second telescopic rod 52 are in the initial position, the second telescopic rod 52 protrudes from the end of the pin body 51 close to the impeller 1, and the portion of the second telescopic rod 52 protruding from the pin body 51 can be inserted into the central hole of the impeller 1 to limit the relative movement of the impeller 1 and the mortise and tenon pin 5 in the radial direction, thereby limiting the radial position of the impeller 1 and the mortise and tenon pin 5 in the connected state. When installing or removing the mortise and tenon pin 5, it is necessary to first pull the second telescopic rod 52 in a direction away from the impeller 1 so that the second telescopic rod 52 does not protrude from the pin body 51, and then slide the pin body 51 in the radial direction to install it into the groove 11.

[0051] The mortise and tenon pin of the embodiment of the present invention comprises a pin body, a second telescopic rod and a second elastic member, the side wall of the pin body can abut against the groove, thereby limiting the circumferential rotation of the pin body relative to the impeller, so that the pin body can stably move radially relative to the impeller; the second telescopic rod protrudes from one end of the pin body close to the impeller, and the part of the second telescopic rod protruding from the pin body can be inserted into the center hole of the impeller to limit the relative movement of the impeller and the mortise and tenon pin in the radial direction, thereby limiting the radial position of the impeller and the mortise and tenon pin in the connected state; the pressure of the second elastic member ensures that the mortise and tenon pin and the impeller can be stably connected in the axial direction, and when the pin body is installed or removed into place, the second telescopic rod that is pulled to avoid the protruding part of the second telescopic rod interfering with the connection between the pin body and the groove can be restored to its original state under the pressure of the second elastic member, ensuring that the protruding part of the second telescopic rod and the center hole of the impeller can also be installed or removed into place.

[0052] In some embodiments, Figure 6 and Figure 7As shown, the wall surface of the pin body 51 adjacent to the through hole 54 is in a step shape, and the second telescopic rod 52 includes a column portion 521 and a handle portion 522 . The side wall of the column part 521 is provided with a protrusion 523 extending outward, and the protrusion 523 abuts against the step at one end of the wall surface adjacent to the pin body 51 and the through hole 54 in the axial direction. The step at the wall surface adjacent to the pin body 51 and the through hole 54 has two ends in the axial direction. Therefore, the second telescopic rod 52 moves in the two end spaces at the step at the wall surface adjacent to the pin body 51 and the through hole 54 under the restriction of the protrusion 523; the handle part 522 is connected to the end of the column part 521 away from the impeller 1 in the axial direction. Pulling the handle part 522 can drive the column part 521 and the protrusion 523 to move axially together; wherein the second elastic member 53 is sleeved outside the side wall of the column part 521, and the second elastic member 53 abuts between the protrusion 523 and the step at the other end, that is, the second elastic member 53 is located in the two end spaces at the step at the wall surface adjacent to the pin body 51 and the through hole 54.

[0053] The second telescopic rod of the embodiment of the present invention includes a column part and a handle part. The side wall of the column part is provided with a protrusion extending outward, and the protrusion abuts against the step at one end of the wall surface adjacent to the through hole of the pin body in the axial direction, and the second elastic member abuts between the protrusion and the step at the other end of the wall surface adjacent to the through hole of the pin body, so that the second elastic member presses the protrusion to press the column part to stabilize it in the initial position, so that the part of the column part protruding from the pin body can be stably inserted into the center hole of the impeller, thereby realizing stable limiting. The setting of the handle part makes it convenient for holding the handle part to pull the column part to move axially.

[0054] like Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides a clothing processing device, for example, the clothing processing device can be a stirring washing machine, etc. The clothing processing device includes a barrel body and a pulsator assembly 10. Among them, the barrel body has a accommodating cavity for accommodating clothing; the pulsator assembly 10 is located in the accommodating cavity and the pulsator 1 is connected to the bottom of the barrel body. When the clothing processing device is dehydrating, the pulsator 1 and the barrel body both rotate; when washing, the pulsator 1 rotates, the barrel body does not rotate, and the pulsator 1 drives the stirring rod 2 to rotate together, thereby driving the water flow in the body and the movement of clothes; the moving water flow pushes the clothes to turn over continuously, so that the clothes, the clothes and the barrel wall and the stirring rod rub in the water, and the decontamination and cleaning are achieved under the action of the detergent.

[0055] The clothing processing device of the embodiment of the present invention comprises a barrel body and a pulsator assembly, wherein the pulsator is connected to the bottom of the barrel body. When washing clothes, the pulsator rotates forward and reversely and drives the stirring rod to rotate together, thereby driving the water flow in the body and the movement of clothes; the moving water flow pushes the clothes to turn over continuously, so that the clothes, the inner wall surface of the barrel body and the stirring rod rub against each other in the water, and decontamination and cleaning are achieved under the action of detergent. When the pulsator rotates forward and reversely and drives the stirring rod to rotate together, the stirring rod is subjected to a large rotational resistance due to the friction between the clothes and the stirring rod in the water, so that the structure for limiting the rotation of the pulsator and the stirring rod needs to bear a large rotational resistance. The connection between the pulsator and the stirring rod of the embodiment of the present invention is stable, so that when the pulsator drives the stirring rod to rotate together, the structure for limiting the rotation of the pulsator and the stirring rod is not easy to break, so that the stirring rod and the pulsator can be stably limited and rotate together.
