Technical scheme of the present invention can also be described as follows:

The wall-mounted drum washing machine is mainly composed of a cabinet, an outer cylinder 1, an inner cylinder 3, a driving motor and other auxiliary structures. The inner cylinder 3 is fixed in the outer cylinder 1, and realizes washing and dehydration functions under the drive of the motor. The box body is connected with the outer cylinder 1 to protect the internal circuit and the beautiful appearance. The rear surface of the outer cylinder 1 is a plane, and there are through holes for installing bolts. When the installation is fixed, the rear surface of the outer cylinder 1 is in tight contact with the wall surface through expansion bolts. The cleaning brush (corresponding to the above-mentioned cleaning element 4) is located at the bottom of the outer cylinder 1, one end is fixed on the outer cylinder 1, and the other end is a free end. The installation position is perpendicular to the plane of the inner cylinder 3, in a single row or in other shapes, and the width is equivalent to the height of the inner cylinder 3, mainly considering that the cleaning range can completely cover the outer wall of the inner cylinder 3. The length of the hairbrush is the length after floating and can fully contact the outer wall of the inner tube 3 . The brush is wear-resistant flexible material, its density should be lower than that of washing water, suitable for cleaning metal surface stains and without noise.

The working principle is: when the washing function of the washing machine is turned on, the washing water is filled between the inner and outer drums 1 of the washing machine. With the help of the buoyancy of the water, one end of the hair brush floats and sticks to the outer wall of the inner drum 3. When the inner drum 3 rotates, it will always be in contact with the hair brush. The brush contact functions to clean the surface, preventing the deposition of stains. When the washing machine is dehydrating, it is necessary to drain the water in the cylinder. At this time, the brush loses buoyancy and falls back on the outer cylinder 1 to separate from the outer wall of the inner cylinder 3 . It avoids the noise caused by the high-speed rotation of the inner cylinder 3 and the increased friction and the increased wear of the brush, which increases the service life and improves the user experience.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology of this patent Without departing from the scope of the technical solution of the present invention, personnel can use the technical content of the above prompts to make some changes or modify them into equivalent embodiments with equivalent changes. In essence, any simple modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the solutions of the present invention.
