In the closed state of the door assembly 30 closing the front barrel opening 201, the flexible sealing ring 304 is in sealing butt joint with the connecting ring 1, the aim of closing the front barrel opening 201 can be achieved through the sealing butt joint of the flexible sealing ring 304 and the connecting ring 1, and a good sealing effect can be achieved.

Generally, laundry treatment apparatuses such as drum washing machines in the market are provided with a door gasket, which is engaged with a door assembly for sealing purposes. The commonly used door seal ring is mostly made of rubber. After the clothes processing equipment such as a drum washing machine is used for a long time, the door sealing ring is easy to have the defects of blackening, incrustation, mold and the like. These drawbacks can lead to a very poor user experience for the user.

According to the clothes treatment equipment 100 of the embodiment of the invention, the connecting ring 1 is arranged on the outer cylinder 20, the connecting ring 1 is arranged around the front cylinder opening 201, the flexible sealing ring 304 is arranged in the door assembly 30, and the flexible sealing ring 304 seals a gap between the door inner ring 302 and the door glass 301 on one hand, and is in sealing and abutting joint with the connecting ring 1 in a state that the door assembly 30 is closed on the other hand, so that the problem of poor sealing can be effectively solved, the problem of water leakage or air leakage of the clothes treatment equipment 100 is avoided, and meanwhile, as a part of the flexible sealing ring 304 is hidden between the door inner ring 302 and the door glass 301, the problem of poor appearance caused by the defects of blackening, mould, mildew and the like of the flexible sealing ring 304 is avoided at least to a certain extent, and the use experience of a user is improved at least to a certain extent.

Other configurations and operations of the laundry treating apparatus 100 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
