Due to uneven ground, household appliances are generally equipped with a leveling device at the bottom of the casing. When placing household appliances, the leveling device can be adjusted to achieve a stable placement state. After leveling and placement, the leveling device can also support Home appliances keep it stable.

Take the washing machine as an example. Due to the large vibrations generated when the washing machine is working, when the floor where the washing machine is placed is uneven, the washing machine will move during operation. This will not only aggravate the vibration and noise of the washing machine, but also make it very unsafe. Worse, the washing machine is also easily damaged by hitting other objects. Existing washing machines are generally equipped with leveling feet on the bottom of the casing or the whole machine. Although the leveling of the washing machine is achieved, the distance between the bottom of the washing machine and the ground is small, and the thin gap between the bottom of the washing machine and the ground is extremely small. It is easy to harbor dirt and breed mold, making it difficult for users to clean the small gaps; and because the body of the washing machine is heavy and difficult to move, it is very difficult for users to clean the floor under the household appliances.

In addition, if the washing machine is placed in the bathroom or other humid environment, due to the small distance between the washing machine and the ground and poor ventilation, water mist will easily condense on the inner surface of the washing machine box, which will easily lead to corrosion of the inner wall of the box over a long period of time. Reduce the service life of the washing machine.

In order to improve the support stability of the washing machine and facilitate cleaning of dirt between the washing machine and the floor, feet are usually provided at the bottom of the washing machine for supporting the washing machine and for adjusting the height of the washing machine. However, the height adjustment of the existing feet is limited, and the feet are movable and have poor stability. After the washing machine has been used for a period of time, the height of individual feet may change due to the vibration of the washing machine, which may cause the washing machine to become uneven on the ground, requiring the user to adjust the feet after a period of time, which reduces the user experience.

Therefore, some manufacturers have studied auxiliary devices, such as movable brackets supported under the washing machine. The Chinese patent application with application number CN201810364557.1 discloses an aluminum movable bracket that facilitates the movement of the washing machine, including aluminum profiles. The bracket frame is made, and the corners of the bracket frame are equipped with a supporting body made of aluminum sheets with a right-angled triangle shape. The supporting body includes an L-shaped bending part and a supporting piece part. The L-shaped bending part It is sleeved on the corresponding side of the bracket frame. The support piece is located inside the corner of the corresponding bracket frame. The upper surface of the support piece is provided with anti-slip circular protrusions distributed at equal intervals. The corners of the bracket frame A universal wheel is provided below, and feet are provided on the universal wheel. Although the above solution can move the washing machine and clean the floor at the bottom of the washing machine, moving the washing machine requires additional space. The inlet and drain pipes of the washing machine, especially the drain pipes, must be pulled out from the drain outlet, otherwise they will be easily damaged and cause the risk of water leakage. , which is inconvenient for users to operate.

In view of this, the present invention is proposed.
