[0039] Currently, most of the existing washing machines have the agitator assembly and the output shaft of the driving component fixed and connected through threaded connectors. The disassembly and installation of the agitator assembly require professional operation, resulting in time-consuming disassembly and installation of the agitator assembly. In the present invention, a limiting part is provided on the box cover of the agitator box, so that the quick installation and disassembly of the agitator body can be realized without the need for external tools.

[0040] To further elaborate on the technical solutions in the present invention, the following specific embodiments are provided in combination with Figures 1-6 as shown.

[0041] Embodiment 1

[0042] In an embodiment of the present invention, there is provided a kind of as Figures 1-3The shown pulsator washing machine includes a pulsator shaft 1 installed at the bottom of the inner drum of the washing machine and a pulsator body 2 sleeved on the pulsator shaft 1. Among them, the pulsator body 2 is connected to the pulsator shaft 1 in the form of a spline. The pulsator shaft 1 is configured to limit the radial and circumferential movement of the pulsator body 2 relative to the pulsator shaft 1 and can drive the pulsator body 2 to rotate.

[0043] It further includes a pulsator box 3 fixedly covered on the middle part of the pulsator body 2. The pulsator box 3 is a round box and is installed on the pulsator body 2 by means of screw fastening. Among them, the shaft extension end of the pulsator shaft 1 is placed inside the pulsator box 3. A limiting groove is opened on the pulsator shaft 1. The opening end of the pulsator box 3 is provided with a box cover 4. The box cover 4 can close or open the pulsator box 3. A limiting portion 41 is provided on the box cover 4. When the box cover 4 closes the pulsator box 3, the limiting portion 41 on the box cover 4 can be embedded in the limiting groove to limit the axial movement of the pulsator body 2 relative to the pulsator shaft 1. After the box cover 4 opens the pulsator box 3, the limiting portion 41 can be disengaged from the limiting groove to realize the disassembly of the pulsator body 2.

[0044] As Figure 2 and Figure 4 shown, when the pulsator body 2 and the pulsator shaft 3 are installed, the box cover 4 at this time closes the opening of the pulsator box 3, and the limiting portion 41 on the box cover 4 is embedded in the limiting groove on the pulsator shaft 1, thereby restricting the axial movement of the pulsator body 2 relative to the pulsator shaft 1.

[0045] As Figure 3 and Figure 6 shown, when it is necessary to remove the pulsator body 2 from the pulsator shaft 3, the box cover 4 at this time opens the opening of the pulsator box 3, and the limiting portion 41 on the box cover 4 is disengaged from the limiting groove on the pulsator shaft 1. At this time, the limiting portion 41 is separated from the limiting groove, and at this time, the pulsator body 2 can be pulled out from the pulsator shaft 2, thereby realizing the rapid disassembly of the pulsator body 2.

[0046] The following is a specific description of the box cover 4 of the pulsator box 3:

[0047] The above-mentioned box cover 4 is an integral cover body. Specifically, as Figure 3 and Figure 6 shown, one end of the above-mentioned box cover 4 is hinged on the peripheral wall of the pulsator box 3, and the other end can be turned around its hinge axis to open or close the pulsator box 3.

[0048] Of course, in some alternative embodiments, the above-mentioned pulsator box 3 may also be a split cover. When the box cover 4 is a split cover, the box cover 4 at this time includes a first cover body and a second cover body arranged oppositely. The above-mentioned limiting part 41 is provided on both the first cover body and the second cover body. One end of each of the first cover body and the second cover body is hinged on the circumferential walls on both radial sides of the pulsator box 3. The free ends of the first cover body and the second cover body can be respectively turned around their hinged ends to open or close the pulsator box 3. When the first cover body and the second cover body close the pulsator box 3, the two limiting parts 41 on the first cover body and the second cover body are both embedded in the limiting grooves on the pulsator shaft 1 to jointly limit the axial movement of the pulsator body 2 relative to the pulsator shaft 1. By setting the box cover 4 as a split cover and providing the limiting parts 41 on both cover bodies, the axial limiting effect of the pulsator body 2 on the pulsator shaft 1 can be further improved.

[0049] It should be noted that, as Figure 1 and Figure 6 shown, when the box cover 4 is a split cover, the first cover body can also be designed as a flip cover 42 rotatably arranged on the pulsator box 3 and the second cover body can be designed as a fixed cover 43 fixedly arranged on the circumferential wall of the pulsator box 3. Among them, the limiting part 41 is formed on the flip cover 42. When the flip cover 42 is rotated, the limiting part 41 on the flip cover 42 can be embedded in the limiting groove on the pulsator shaft 1 to limit the axial movement of the pulsator body 2 relative to the pulsator shaft 1. Specifically, as Figure 1 and Figure 4As shown, the flip cover 42 has a rotating shaft, and a shaft hole 46 adapted to the rotating shaft is provided on the pulsator box 3. The rotating shaft on the flip cover 42 is installed in the shaft hole on the pulsator box 3 so that the flip cover 42 can be flipped relative to the pulsator box 3. Specifically, the shaft hole 46 on the pulsator box 3 includes a first shaft hole 461 and a second shaft hole 462 provided relative to the center of the pulsator box 3. Among them, the first shaft hole 461 is a circular through hole penetrating the outer peripheral wall of the pulsator box 3, and the second shaft hole 462 is a notch formed at the top of the outer peripheral wall of the pulsator 3. The rotating shaft on the flip cover 42 is rotatably arranged on the through hole and the notch. A fixed cover tab 431 is provided on the fixed cover 43. When the fixed cover 43 is installed on the pulsator box 3, the pulsator cover tab 431 covers the notch to limit the up and down movement of the rotating shaft. More specifically, when installing the flip cover 42, the rotating shaft provided near the first shaft hole 461 on the flip cover 42 is inserted into the first shaft hole 461 by means of side assembly, and the rotating shaft provided near the second shaft hole 462 on the flip cover 42 is inserted into the second shaft hole 462 by means of surface pressing assembly. After installing the flip cover 42, the fixed cover 43 is assembled with the pulsator box 3 by fastening means such as snap fasteners, glue or screws, etc. It is necessary to ensure that there is no looseness after the pulsator fixed cover 43 is assembled. When the fixed cover 43 is assembled, at this time, the fixed cover tab 431 on the fixed cover 43 covers the second shaft hole 462 (i.e., the notch) to prevent the up and down movement of the rotating shaft in the second shaft hole 462.

[0050] Furthermore, as Figure 5 and Figure 6 shown, the limiting part 41 includes a first limiting part formed at a position where the box cover 4 faces the pulsator shaft 1. The first limiting part includes a convex arm extending from the inner wall surface of the box cover towards the inside of the pulsator box 3 and a clamping block protruding laterally from the convex arm; a limiting groove is formed on the circumferential surface of the pulsator shaft 1 corresponding to the position of the clamping block, and the clamping block and the limiting groove are snap-fitted laterally on the pulsator shaft. When the box cover 4 closes or opens the pulsator box 3, the clamping block can be embedded in the limiting groove or disengaged from the limiting groove to realize the installation and disassembly of the pulsator body 2.

[0051] More specifically, the above-mentioned limiting part 41 includes an L-shaped clamping block formed towards the inner bottom surface of the pulsator box 3. Among them, the L-shaped clamping block includes a first side perpendicular to the box cover 4 and a second side parallel to the box cover 4. The second side of the L-shaped clamping block can be embedded in the limiting groove of the pulsator shaft 1 to limit the axial movement of the pulsator body 2 relative to the pulsator shaft 1. It should be noted that as Figure 5 shown, a fillet is processed at the mating surface where the L-shaped clamping block mates with the limiting groove of the pulsator shaft 1 to prevent the L-shaped clamping block from interfering with the limiting groove of the pulsator shaft 1 during flipping.

[0052] Further, the limiting portion 41 further includes a second limiting portion formed at the other end of the box cover 4 opposite to the hinged end. A clamping groove or bayonet is provided on the peripheral wall of the wave wheel box. When the clamping block of the first limiting portion is in snap-fit with the limiting groove, the second limiting portion is also in snap-fit with the clamping groove or bayonet.

[0053] In order to prevent the washed clothes from entering the wave wheel box 3, in this embodiment, a retaining wall 44 is provided at the edge of the box cover 4. The retaining wall 44 is perpendicular to the surface of the box cover 4. When the box cover 4 is flipped to close the opening on the wave wheel box 3, the retaining wall 44 surrounds the outer peripheral wall of the wave wheel box 3 at this time, thereby preventing the washed clothes from entering the wave wheel box 3 and affecting the normal rotation of the wave wheel shaft 1.

[0054] Furthermore, as Figure 6 shown, the above-mentioned second limiting portion includes a fixing member 45 provided on the retaining wall 44. The fixing member 45 includes a fixing buckle, and a fixing clamping groove adapted to the fixing buckle is provided on the wave wheel box 3. When the box cover 4 closes the wave wheel box 3, the fixing buckle is embedded in the fixing clamping groove to lock and fix the wave wheel box 3 and the box cover 4, thereby further improving the axial limiting effect of the limiting portion 41 on the wave wheel body 2. It should be noted that the mating surface where the buckle (i.e., the fixing member 45) cooperates with the fixing clamping groove is also chamfered to prevent the buckle (i.e., the fixing member 45) from interfering with the fixing clamping groove on the wave wheel box 3 during flipping.

[0055] Of course, in some alternative embodiments, it is not limited to using the fixing buckle method to improve the fixing effect between the wave wheel box 3 and the box cover 4. For example, a magnetic attraction method can also be used to achieve the locking and fixing between the wave wheel box 3 and the box cover 4. When the magnetic attraction fixing method is adopted, the above-mentioned fixing member 45 includes a magnetic attraction member provided on the retaining wall 44. When the box cover 4 closes the wave wheel box 3, the magnetic attraction member on the retaining wall 44 is magnetically fixed to the outer peripheral surface of the wave wheel box 3 at this time. Thereby, the fixing effect between the wave wheel box 3 and the box cover 4 is improved.

[0056] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
