The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

Example one

As shown in fig. 1, the present embodiment provides a wall-mounted washing machine, which includes,

Preferably, as shown in fig. 1 and fig. 2, the inner cylinder cover 6 is arranged coaxially with the inner cylinder 3, the radial dimension of the outer periphery of the inner cylinder cover 6 is greater than or equal to the dimension of the cylinder opening 17 of the inner cylinder, and a ring of sealing ring 32 is arranged at the outer periphery of one side of the inner cylinder cover 6 facing the inner cylinder 3; the seal ring 32 is made of a material such as rubber that can be elastically deformed, and is configured to seal the inner cylinder cover 6 and the inner cylinder opening 17 by the elastic deformation thereof.

In the embodiment shown in fig. 2, the outer casing 1 covers the outer part of the outer cylinder 2, the outer casing 1 is detachably connected with the outer cylinder 2 through a snap structure, and the door 5 is rotatably installed on the outer casing 1 and/or the outer cylinder 2 through a hinge structure. In this embodiment, the door 5 may be mounted on the outer cylinder 2, may be mounted on the outer casing 1, and may be connected to both the outer cylinder 2 and the outer casing 1.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
