Abstract: A hydraulic leveling base comprises a bracket which can be used in a combination and connection manner or independently and a leveling foot mounted below the bracket. Above the bracket is a supporting surface for bearing. A hydraulic medium is provided inside the leveling foot and can flow inside the leveling foot and/or between the leveling feet to achieve the leveling. In the present disclosure, the leveling foot is provided below the bracket of the hydraulic leveling base, the hydraulic medium flows inside the leveling foot and/or between the leveling feet, and so the amount of compression of the leveling foot under bigger pressure is large, the leveling foot under smaller pressure can extends by the action of the liquid pressure, and then automatic height leveling can be achieved.

Abstract: An automatic leveling washing machine includes a shell and a barrel assembly. A bottom plate of the shell has leveling bottom feet with hydraulic medium therein and hydraulic medium flows between leveling bottom feet to execute automatic leveling washing machine. The bottom plate of the shell has mounting grooves for fixing and mounting leveling bottom feet. Hydraulic medium and some gas flows inside each leveling bottom foot or between leveling bottom feet. The amount of compression of the leveling bottom foot which is under bigger pressure is big, and the amount of compression of the leveling bottom foot which is under smaller pressure can still stretch, thereby automatically realizing the leveling of the height. The mounting groove effectively and quickly positions the leveling bottom feet. A circumferential surface of the mounting groove protects the leveling bottom feet and allows high reliability of operation.

Abstract: The bottom of a washing machine is provided with feet that compromise a fixed part and a movable part, and a hollow chamber is formed between the fixed part and the movable part. The hollow chamber is provided with a hydraulic medium. The feet are connected by high-pressure oil pipes, to communicate hollow chambers of the feet. Under the action of pressure, the hydraulic medium can be circulated between hollow chambers of connected feet to realize the expansion and contraction of the movable part, to execute automatic leveling. Under different pressures, the foot is made to automatically adjust adaptively due to the fluidity of the hydraulic medium. The hydraulic medium can flow between the feet, so the adjusting range is larger and can achieve better results.

Abstract: A foot of a washing machine comprises a foot base, a flexible accommodating body and an adjustable foot, a hollow chamber is arranged in the foot base, and the hollow chamber comprises at least a gas chamber for filling gas. The flexible accommodating body is arranged in the hollow chamber and is communicated with the gas chamber, an accommodating chamber is arranged in the flexible accommodating body and is provided with a hydraulic medium. The hydraulic medium can flow to the gas chamber under pressure. An end of the adjustable foot is relatively slidably set in the hollow chamber and the flexible accommodating body is in contact or connected with the adjustable foot. The foot of a washing machine can automatically adjust adaptively due to the fluidity of the hydraulic medium under different pressures.

Abstract: The bottom of a household appliance is provided with leveling feet. The leveling foot comprises a fixed part and a movable part, and a hollow chamber is formed between the fixed part and the movable part. The hollow chamber is provided with a hydraulic medium. Under the action of pressure, the hydraulic medium can be circulated in the hollow chamber inside the leveling foot and/or the hollow chamber between leveling feet to realize the expansion and contraction of the movable part, to execute automatic leveling. The leveling device of a household appliance of the present disclosure, according to the hydraulic principle, is provided with a hydraulic medium in the leveling foot. Under different pressures, the leveling foot is made to automatically adjust adaptively due to the fluidity of the hydraulic medium.

Abstract: Provided is a self-cleaning method for a filter assembly of a washing machine, the method comprising: receiving a user operation instruction for starting a self-cleaning process; executing the self-cleaning process, so as to clean the filter assembly of the washing machine, and before the self-cleaning process is completed, only receiving user operation instructions for turning off the washing machine, pausing the self-cleaning process and unpausing the self-cleaning process, and prohibiting receipt of or ignoring the user operation instructions other than user operation instructions for turning off the washing machine, pausing the self-cleaning process and unpausing the self-cleaning process. According to the present invention, the filter assembly of the washing machine is thoroughly cleaned, prolonging the service life of the filter assembly in the washing machine and ensuring that the filter assembly always has a high filtration flux.

Abstract: A clean-water-washing function control method of a washing machine, the method comprising: step A: receiving a selection instruction of a laundry process; step B: enabling or disabling selection of a clean-water-washing function of the washing machine according to the selection instruction. A user at self-select the laundry process and decide whether to use the water-washing function, so that the control method not only helps guide the user in choosing to wash clothing in a water saving manner, but can also wash the clothing effectively, and protect the clothing and a recycled water filtration system. Moreover, an autonomous and intelligent washing environment is created for the user.
