[0029] The present invention will be described in detail below through embodiments.

[0030] A pulsator washing machine with a detachable drum, such as Figures 1-2 As shown, the pulsator washing machine includes a casing 7, an outer drum 5, a washing drum 6, a flange 10, and a door cover 1. The outer drum 5 is disposed within the casing 7. The flange 10 is disposed on a reduction clutch at the bottom of the outer drum 5, supporting the washing drum 6 disposed within the outer drum 5. The door cover 1 is disposed at the outer opening of the outer drum 5. A detachable structure is provided on the washing drum 6, and a detachable structure cooperating with the flange 10 is provided, allowing the washing drum 6 to be easily removed from the opening of the outer drum 5. This design allows the washing drum of the pulsator washing machine to be easily and quickly disassembled and removed from the outer drum, facilitating cleaning and maintenance of the pulsator washing machine. The flange 10 is mounted and connected to the reduction clutch of the washing machine through mounting holes 104.

[0031] Specifically, such as Figures 1-3 As shown, the detachable structure includes a latch 9, which is located at the edge of the washing drum 6. Correspondingly, the detachable structure's mating structure includes a reinforcing strip 102 and a latch 101. The reinforcing strip 102 is located on the flange 10 and extends upwards along the washing drum wall. The latch 101 is located at the end of the reinforcing strip 102 and corresponds to the position of the latch 9 on the washing drum 6. This structure, with the latch located at the opening of the washing drum and the latch located on the support frame and also at the opening of the outer drum, facilitates installation of the detachable structure and its mating structure during production, and also makes disassembly of the washing drum more convenient.

[0032] Furthermore, such as Figure 4 As shown, a groove 61 is provided on the outer wall of the washing drum 6. The groove 61 is axially arranged on the outer side of the drum wall of the washing drum 6 and engages with the reinforcing strip 102. By providing a groove on the drum wall, the washing drum can remain stable during removal and disassembly, preventing rotation and shaking during disassembly or installation, thus further facilitating the disassembly and installation of the washing drum.

[0033] Furthermore, the bottom of the washing drum 6 is provided with a groove that engages with the flange 10, and correspondingly, the flange 10 is provided with a boss 103 that engages with the bottom of the washing drum 6. The boss and groove allow the washing drum to be installed more neatly and securely on the flange 10.

[0034] Furthermore, the bottom of the washing drum 6 is provided with a pulsator 8 that can rotate relative to the washing drum 6. A metal insert 81 that is axially connected to the washing machine deceleration clutch is embedded in the center of the pulsator 8. The bottom of the pulsator 8 is loosely fitted to the bottom of the washing drum 6 by a limiting ring 82 and a fastening screw 83.

[0035] The washing drum 6 has a balance ring 4 at its opening, and the latch 9 is installed on the outer wall of the balance ring 4. Since the balance ring has a greater mass and stronger material than other parts of the washing drum, the latch 9 is installed on the balance ring 4, making the installation of the latch 9 more secure.

[0036] Specifically, such as Figures 5-6 As shown, the latch 9 includes a lock body 91, a return spring 92, a rotating shaft 93, and a lock head 94. The lock body 91 is rotatably fixed to the upper outer wall of the washing tub 6 via the rotating shaft 93, specifically, it is set on the balance ring 4. The return spring 92 is set on the lock body 91 and located above the rotating shaft 93. The lock head 94 is set on the lock body 91 and located below the rotating shaft 93. According to the lever principle, when the part of the lock body 91 located on the rotating shaft 93 tilts, the lock head 94 can engage or disengage with the latch 101.

[0037] Furthermore, a portion of the spring body of the return spring 92 can be securely fixed inside the balance ring 4 to make the return spring 92 more stable and prevent it from swinging arbitrarily.

[0038] When the washing drum does not need to be disassembled, the washing drum 6 and the outer drum 3 are fixed together by a detachable structure and a detachable structure mating structure, as follows: Figure 5 As shown, the return spring 92 of the latch 9 has a spring force that pushes the lock body 91 to the right (taking the direction in the figure as an example, the same below). Due to the lever principle, the lock head 94 located below the pivot 93 moves to the left, that is, it engages with the latch 101 at the same height. At this time, the washing tub 6 is fixedly connected to the outer tub 3.

[0039] When it is necessary to disassemble the washing drum, specifically as follows: Figure 6 As shown, under the action of external force (such as manual action by a person), the upper end of the lock body 91 of the latch 9 is subjected to a force to the left, and this force to the left is greater than the elastic force of the return spring 92. Due to the lever principle, the lock head 94 located below the pivot 93 moves to the right, causing the lock head 94 to separate from the latch 101. At this time, the washing tub 6 can be disassembled and separated from the outer tub 3. Simply pull up the washing tub 6 to remove the washing tub.

[0040] The outer cylinder 5 is movably installed inside the housing 7. The top of the housing 7 is provided with a cover 2, and the cover 2 is provided with a door cover 1 that can be opened to facilitate the removal of the washing cylinder 6.

[0041] The washing drum 6, the impeller 8, and the balance ring 4 form a single assembly that can be quickly removed from the outer drum 5. The inner diameter of the outer drum ring 3 at the top of the outer drum 5 and the diameter of the middle opening of the lid 2 are both larger than the outer diameter of the washing drum 6.

[0042] When the washing tub 6 assembly is placed into the outer tub 5, the latch 9, under the action of the return spring 92, rotates the lock body 91, causing the lock head 94 to engage with the latch 101 of the reinforcing strip 102 of the flange 10 and lock itself. This is a dead point and will not fall off on its own. To remove the washing tub 6, press the lock body 91 of the latch 9 by hand and rotate it to disengage the lock head 94 from the latch 101. Then pull up the washing tub 6 to remove it.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
