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 1400r / min for 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] Also, the vibration caused by the unevenness of the washing machine may loosen the foot screws, causing the foot bracket to move vertically, this instability may change the level of the washing machine, resulting in stronger vibration
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.

Embodiment 1

[0057] Such as Figure 1-Figure 6 As shown, a hydraulic leveling device for household appliances in this embodiment includes a hydraulic foot 100. The hydraulic foot 100 includes a fixed part and a movable part. The chamber is filled with hydraulic medium in the chamber.

[0058] At least two of the hydraulic feet 100 are connected through a communication device. Under pressure, the hydraulic medium circulates between the hydraulic feet 100 , and the movable part of the hydraulic feet 100 expands and contracts accordingly for leveling.

[0059] The hydraulic leveling device for household appliances in this embodiment is based on the principle of hydraulic pressure. Due to the different pressures caused by unevenness, the fluidity of the hydraulic medium makes the movable part automatically adjust adaptively until the hydraulic medium in the hydraulic foot reaches balance and stops circulation. , to achieve automatic leveling.

[0060] The leveling effect of the hydraulic lev...

Embodiment 2

[0077] Such as Figure 7-Figure 12 As shown, a hydraulic foot of the present embodiment includes:

[0078] Hydraulic plate 101;

[0079] The sheath 103 is fixedly connected with the hydraulic plate 101;

[0080] The adjustment foot 104 is arranged in the sheath 103 and can move axially relative thereto;

[0081] An accommodating chamber is formed between the hydraulic plate 101, the sheath 103 and the adjustment foot 104;

[0082] The hydraulic medium 102 is arranged in the accommodating chamber, and as the pressure changes, the hydraulic medium compresses / expands to drive the adjusting foot 104 to move axially in the sheath 103 for leveling.

[0083] The hydraulic foot of this embodiment is based on the principle of hydraulic pressure. Due to the different pressures caused by unevenness and the fluidity of the hydraulic medium, the adjustment foot is automatically adjusted adaptively until the hydraulic foot reaches balance, and the flow of the hydraulic medium stops to ac...

Embodiment 3

[0138] Such as Figure 7-Figure 12 , Figure 13 and Figure 14 As shown, a hydraulic foot of the present embodiment includes:

[0139] Hydraulic plate 101;

[0140] The sheath 103 is fixedly connected with the hydraulic plate 101;

[0141] The adjustment foot 104 is arranged in the sheath 103 and can move axially relative thereto;

[0142] An accommodating chamber is formed between the hydraulic plate 101, the sheath 103 and the adjustment foot 104;

[0143] The hydraulic medium 102 is arranged in the accommodation chamber, and as the pressure changes, the hydraulic medium compresses / expands to drive the adjusting foot to move axially in the sheath for leveling;

[0144] The overall height h and lateral length D of the hydraulic feet are respectively determined by the specification parameters of the installed household appliances.

[0145] The hydraulic foot of this embodiment is based on the principle of hydraulic pressure. Due to the different pressures caused by uneve...

Abstract

The invention provides a hydraulic leveling device for a household appliance and the household appliance. The hydraulic leveling device for the household appliance comprises at least two hydraulic bottom feet, the hydraulic bottom feet comprise fixed portions and movable portions, the fixed portions are movably connected with the movable portions, containing cavities are formed between the fixed portions and the movable portions and filled with hydraulic media, the hydraulic bottom feet communicate through a communicating device, under the pressure effect, the hydraulic media flow among the hydraulic bottom feet, the movable portions of the hydraulic bottom feet are stretched and retracted for leveling, the communicating device comprises a hydraulic pipe connected with the hydraulic bottomfeet for flowing of the hydraulic media inside the hydraulic bottom feet, and the hydraulic bottom feet and the hydraulic pipe are in sealed connection through an elastic clamping device capable of being elastically deformed or reset. Since the hydraulic bottom feet and the hydraulic pipe are in sealed connection through the elastic clamping device capable of being elastically deformed or reset,elastic deformation of the elastic clamping device facilitates installation of the hydraulic pipe, and after the hydraulic pipe is installed, the elastic clamping device is elastically reset to keep sealed connection.

Description

technical field [0001] The invention relates to the technical field of leveling of household appliances, in particular to a hydraulic leveling device for household appliances and the household appliances. 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 the washing mach...
