Hydraulic lifting bottom legs, washing machine with bottom legs and control method of washing machine

Abstract

The invention provides hydraulic lifting bottom legs, a washing machine with the bottom legs and a control method of the washing machine. The hydraulic lifting bottom legs include hydraulic bottom legbodies, a communicating device and a liquid storage device. The hydraulic bottom leg bodies include a fixing part and a movable adjusting part, wherein the fixing part is installed on the bottom of ahousehold appliance, and the movable adjusting part sleeves the fixing part and can relatively move in the axial direction. A containing cavity for containing a hydraulic medium is formed between thefixing part and the movable adjusting part; at least two hydraulic bottom leg bodies and the liquid storage device are communicated with each other through the communicating device. Along with the changes of pressure, the hydraulic medium flows among the hydraulic bottom leg bodies and drive the movable adjusting part to move axially under the action of pressure for levelling. The hydraulic medium is injected into / sucked out of the hydraulic bottom leg bodies through the liquid storage device, and lifting adjustment of the hydraulic bottom legs is controlled. The hydraulic lifting bottom legs are particularly applicable to a roller washing machine, the supporting height of the hydraulic bottom leg bodies is increased by means of the liquid storage device in order to lift an opening of adoor body, and therefore the water level is lower than the opening of the door body so that the door body can be opened for adding clothes during running of the washing machine.

Description

technical field [0001] The invention relates to the technical field of support and leveling of household appliances, in particular to a hydraulic lifting foot, a washing machine with the foot and a control method thereof. Background technique [0002] Household appliances are generally equipped with a leveling device at the bottom of the shell. When placing the household appliance, the leveling device can be adjusted to make it reach a stable placement state. After leveling and placing, the leveling device can support the household appliance to keep it Stablize. [0003] Taking the washing machine as an example, the existing washing machines are generally equipped with bolt feet at the bottom of the shell or the whole machine. The bolt feet include screw rods, nut washers and rubber pads. The nut washers can be rotated up and down on the screw rods, and the screw rods can also be Rotate up and down in the screw hole of the bottom plate of the shell, and adjust the height of...

AI Technical Summary

Problems solved by technology

[0004] Although the feet of the above-mentioned washing machine realize the leveling of the washing machine, the user needs to manually adjust it. If the washing machine has a large weight or the installation space is small, the user's operation is inconvenient

In addition, the vibration of the washing machine during the long-term working process also has an effect on the leveling feet, which can easily lead to the failure of its support and cause the washing machine to be placed unevenly.

[0005] For example, the existing 8KG drum washing machine is generally about 80Kg, which is relatively heavy, and it is extremely inconvenient for consumers to adjust. Even if the adjustment is completed, the washing machine cannot be adjusted to the best state. The washing machine is accelerated from 0r / min to about 1600r / min when washing. During drying and dehydration, once the washing machine is not level or there is a problem with weak legs, it will cause great vibration, which greatly affects the comfort of consumers

[0006] The vibration caused by the unevenness of the washing machine may loosen the foot screws, allowing the foot brackets to move vertically, this instability may change the level of the washing machine, resulting in stronger vibrations

This vicious cycle makes the washing machine use for a long time, the noise will become louder, and it will also cause some damage to the washing machine itself, shortening the service life.

[0007] Therefore, the leveling of the existing washing machine requires manual adjustment, which is time-consuming, laborious and has poor precision.

[0008] In addition, there is the problem of adding clothes in the middle of the drum washing machine, but the washing outer drum of the drum washing machine is generally set horizontally. After the washing water is filled, sometimes the liquid level exceeds the seal of the door and window. Once opened, the washing water will spurt Therefore, in the existing technology, after the washing program is started, consumers cannot open the doors and windows to add clothes in the middle, but it brings great inconvenience to consumers when they need to add clothes.
