[0035] The present invention will be described in detail below through examples.

[0036] A drum washing machine with a detachable washing drum, such as Figure 1 to Figure 7 As shown, the drum washing machine comprises a housing 4, an outer drum 3, a support frame 33, a washing drum 2 and a door cover 1. The outer drum 3 is arranged in the housing 4, the support frame 33 is arranged inside the outer drum 3, and is used to support the washing drum 2 arranged in the outer drum 3. The door cover 1 is arranged at the outer opening of the outer drum 3. A detachable structure is arranged on the washing drum 2, and a detachable structure matching structure cooperating with the detachable structure is arranged on the support frame 33, so that the washing drum 2 can be conveniently taken out from the opening of the outer drum 3. With such a design, the washing drum of the drum washing machine can be conveniently and quickly disassembled and taken out from the outer drum, which is convenient for cleaning and maintenance of the drum washing machine.

[0037] Specifically, the detachable structure includes a self-locking device 26, and the self-locking device 26 is arranged at the edge of the barrel opening of the washing tub 2. Correspondingly, the detachable structure matching structure includes a lock buckle 31, and the lock buckle 31 is arranged on the support frame 33 and corresponds to the barrel opening edge position of the washing tub 2. The structure in which the self-locking device and the lock buckle are matched, and the self-locking device is arranged at the barrel opening position of the washing tub, and the lock buckle is arranged on the support frame and is also at the barrel opening position of the outer tub, on the one hand, makes it easy to install the detachable structure and the detachable structure matching structure itself during the production process, and on the other hand, makes it more convenient to disassemble the washing tub.

[0038] Furthermore, a guide rail 25 is provided on the wall of the washing tub 2, and the guide rail 25 is axially arranged on the outer side of the wall of the washing tub 2; the self-locking device 26 is specifically arranged on the end of the washing tub 2 close to the guide rail 25. The manner of providing the guide rail on the wall of the washing tub can keep the washing tub stable during the process of taking out and unloading, and will not fall during the process of disassembly or installation, which further facilitates the disassembly and installation of the washing tub.

[0039] Furthermore, the support frame 33 is connected with a guide groove column 32 which is slidably matched with the guide rail 25 , and the lock buckle 31 is arranged at the end of the guide groove column 32 extending toward the outer opening of the outer tube 3 .

[0040] Furthermore, a groove 24 engaging with the support frame 33 is provided on the bottom of the washing tub 2, so that the washing tub can be installed on the support frame 33 more neatly and firmly.

[0041] Furthermore, the wall of the washing tub 2 is provided with a water-repelling rib 21, and the guide rail 25 is arranged in the recessed space on the back of the water-repelling rib 21; the mouth of the washing tub 2 is provided with a balancing ring 22, and the wall is provided with a water-repelling hole 23; the self-locking device 26 can be further arranged on the balancing ring 22. In this way, the guide rail 25 can be arranged on the wall of the washing tub 2 more compactly, saving space, and the self-locking device 26 is arranged on the balancing ring 22. Since the balancing ring has a larger mass and a greater material strength than other parts of the washing tub, the self-locking device 26 is arranged on the balancing ring 22, so that the installation of the self-locking device 26 is more stable.

[0042] Furthermore, a rotating shaft 34 is provided at a position corresponding to the bottom of the outer drum 3 and the bottom of the washing drum 2. The rotating shaft 34 is movably installed in the center hole at the bottom of the outer drum 3 through a bearing 35 and a water seal. The rotating shaft 34 passes through the center hole at the bottom of the outer drum 3 and is connected to a pulley 36; the support frame 33 is installed and connected to the rotating shaft 34.

[0043] Specifically, Figure 8As shown, the self-locking device 26 includes a lock body 261, and a positioning pin 266 is provided on the lock body 261 for locking or separating with the lock buckle 31; the positioning pin 266 is pushed out or retracted by controlling a lock core 263 that moves up and down in the lock body 261 to achieve the effect of locking or separating with the lock buckle 31.

[0044] Specifically, Fig. 9 As shown, a return spring 267 is provided between the positioning pin 266 and the lock body 261, and a stepped surface 269 is provided on the lock core 263, and the stepped surface 269 can facilitate the sliding of the positioning pin 266; a spring sheet 262 is provided on the lock body 261, and the spring sheet 262 is used to elastically support the lock core 263.

[0045] Specifically, Figure 8 As shown, a positioning rib 265 is provided on the lock core 263 , and a limiting rod 268 for locking the positioning rib 265 is also provided on the front side of the lock body 261 .

[0046] When the washing tub does not need to be disassembled, the washing tub 2 and the outer tub 3 are fixed to each other through a detachable structure and a detachable structure matching structure. Fig.10 As shown, the lock core 263 of the self-locking device 26 is located below the lock body 261 (taking the direction in the figure as an example, the same below), so that the stepped surface 269 on the lock core 263 squeezes the positioning pin 266 out of the lock body 261 and engages with the lock buckle 31 on the support frame 33. At this time, the washing drum 2 is fixedly connected to the outer drum 3.

[0047] When you need to disassemble the washing drum, Fig. 9 As shown, the lock core 263 of the self-locking device 26 is located in the middle of the lock body 261, so that the stepped surface 269 on the lock core 263 retreats to the upper part of the lock body 261. At this time, the positioning pin 266 that was originally squeezed out of the lock body 261 is reset to the inside of the lock body 261 under the action of the reset spring 267, and then separated from the lock buckle 31 on the support frame 33. At this time, the washing drum 2 and the outer drum 3 can be disassembled and separated.

[0048] 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 in the scope of protection of the present invention.
