The technical scheme of the invention can also be described as follows:
the wall-mounted drum washing machine mainly comprises a box body, an outer barrel 1, an inner barrel 3, a driving motor and other auxiliary structures. The inner cylinder 3 is fixed in the outer cylinder 1 and realizes the functions of washing and dehydration under the drive of a motor. The box body is connected with the outer barrel 1 to protect the internal circuit and beautify the appearance. The rear part of the outer cylinder 1 is a plane and is provided with a through hole for installing a bolt, and the rear surface of the outer cylinder 1 is in fastening contact with a wall surface through an expansion bolt when the outer cylinder is fixedly installed. The cleaning brush (corresponding to the cleaning piece 4) is positioned at the bottom of the outer cylinder 1, one end of the cleaning brush is fixed on the outer cylinder 1, and the other end of the cleaning brush is a free end. The installation position is vertical to the plane of the opening of the inner cylinder 3, the single-row or other shapes are formed, the width is equivalent to the height of the inner cylinder 3, and the outer wall of the inner cylinder 3 can be completely covered mainly in consideration of the cleaning range. The length of the brush is the length after floating and can fully contact the outer wall of the inner barrel 3. The brush is made of wear-resistant flexible material, the density of the brush is lower than that of washing water, and the brush is suitable for cleaning stains on the surface of metal and has no noise.
The working principle is as follows: when the washing function of the washing machine is started, the space between the inner barrel 1 and the outer barrel 1 of the washing machine is filled with washing water, one end of the brush floats by virtue of the buoyancy of the water and is attached to the outer wall of the inner barrel 3, and the inner barrel 3 can always contact with the brush to play a role in cleaning the surface when rotating, so that the deposition of stains is prevented. When the washing machine dehydrates, the water in the barrel needs to be drained, and at the moment, the brush loses buoyancy and falls back to the outer barrel 1 to be separated from the outer wall of the inner barrel 3. The noise and the brush aggravation loss caused by the high-speed rotation aggravation friction of the inner barrel 3 are avoided, the service life is prolonged, and the use experience is improved.
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.
