Problems solved by technology

[0003] However, since the inner cylinder and the outer cylinder are interfitted with each other, dirt is easy to accumulate between the inner and outer cylinders during the use of the washing machine; at the same time, because the inner and outer cylinders are intertwined, the user cannot clean the outer wall of the inner cylinder and the inner wall of the outer cylinder, which increases the number of bacteria in the washing machine , reducing the washing efficiency of the washing machine and the cleanliness of the clothes after washing
[0004] Simultaneously, in the above-mentioned existing washing machine, because the inner cylinder is equipped with an outer cylinder, the washing process of the washing machine is to beat and wash the clothes through the rotation of the inner cylinder, so that the washing capacity of the washing machine is based on the inner cylinder, so that the internal space utilization rate of the washing machine is Low, unable to expand the washing capacity of the washing machine on the existing basis

Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a drum washing machine in this embodiment includes a body 3, a door body 5 and an inner cylinder 7, the inner cylinder 7 is rotatably arranged in the body 3, and the inner cylinder 7 holds water during the washing process; The front portion of the inner cylinder 7 is provided with an opening for picking and placing clothes, and the door body 5 can be opened / closed and installed on the front portion of the body 3 and corresponds to the insertion opening of the inner cylinder 7; on the door body 5 or the door A rotatable sealing sleeve 24 is arranged on the body 3 on the outer periphery of the body 5 , and the insertion port end of the inner cylinder 7 is sealedly connected with the sealing sleeve 24 .

[0031] The inner cylinder 7 of the drum washing machine of this embodiment is a non-porous inner cylinder without dehydration holes on the cylinder wall. When washing, the inner cylinder 7 contains washing...

Embodiment approach

[0033] As an embodiment of the present invention, the inner side of the door body 5 in this embodiment is provided with an annular seat body 26, and the sealing sleeve 24 is rotatably sealed and installed in the annular seat body 26, and the injection of the inner cylinder 7 A sealing connector is arranged on the periphery of the mouth, and the sealing connector is sealed and connected with the sealing sleeve 24 as a whole. The sealing connector drives the sealing sleeve 24 to rotate relative to the body 3 as the inner cylinder 7 rotates. In this embodiment, the seal is realized through the cooperation between the rotatable sealing sleeve 24 on the door body 5 and the sealing connector on the inner cylinder 7. The two are separated when the door body 5 is opened, and are dynamically and sealed when the door body 5 is closed. The structure is simple and does not affect the opening and closing of the door body 5 .
