A hydraulic lifting foot, a washing machine with the foot and a control method thereof

Abstract

The invention provides a hydraulic lift foot, a washing machine with the foot and a control method thereof. The hydraulic lift foot includes a hydraulic foot, a communication device, and a liquid storage device. The hydraulic foot includes: a fixing part installed on a household appliance the bottom of the bottom; the movable adjustment part is sheathed with the fixed part and can move axially relative to it; there is an accommodation chamber for accommodating the hydraulic medium between the fixed part and the movable adjustment part; at least two hydraulic feet, storage The hydraulic devices communicate with each other through the communication device: as the pressure changes, the hydraulic medium circulates between the hydraulic feet and drives the movable adjustment part to move axially for leveling under the pressure; it is injected into the hydraulic feet through the liquid storage device / Suck out the hydraulic medium and control the lifting adjustment of the hydraulic feet. The hydraulic lifting feet of the present invention are especially suitable for drum washing machines. The liquid storage device raises the support height of the hydraulic feet to raise the door opening so that the water level is lower than the door opening, so that the door can be opened midway by adding clothes.

Description

Technical field[0001]The invention relates to the technical field of support and leveling of household appliances, and 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 housing. When placing the household appliance, the leveling device can be adjusted to achieve a stable placement. After leveling, the leveling device can support the household appliance to keep it stable.[0003]Take washing machines as an example. Existing washing machines are generally equipped with bolt feet on the bottom of the casing or the whole machine. The bolt feet include a screw, a nut washer and a rubber washer. The nut washer can rotate up and down the screw, and the screw can also be Rotate up and down in the screw hole of the bottom plate of the housing, and adjust the height of the washing machine by screwing the screw of the bolt foot in...

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.
