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 in 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 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

[0047] Such as Figure 2-Figure 6 As shown, a footing for a household appliance in this embodiment includes:

[0048] Hydraulic plate 101;

[0049] The sheath 103 is fixedly connected with the hydraulic plate 101;

[0050] The adjustment foot 104 is arranged in the sheath 103 and can move axially relative thereto;

[0051] An accommodating chamber is formed between the hydraulic plate 101, the sheath 103 and the adjustment foot 104;

[0052]The hydraulic medium 102 is arranged in the accommodating chamber, and as the pressure changes, the hydraulic medium 102 compresses / expands to drive the adjustment foot 104 to move axially in the sheath 103 for leveling;

[0053] At least two feet 100 for household appliances are connected to each other to realize the circulation of hydraulic medium between the feet for household appliances;

[0054] The hydraulic plate 101 is provided with a liquid channel for hydraulic medium circulation, and at least one of the connected household ap...

Embodiment 2

[0074] Such as Figure 7-Figure 14 As shown, a footing for a household appliance in this embodiment includes:

[0075] Hydraulic plate 101;

[0076] The sheath 103 is fixedly connected with the hydraulic plate 101;

[0077] The adjustment foot 104 is arranged in the sheath 103 and can move axially relative thereto;

[0078] An accommodating chamber is formed between the hydraulic plate 101, the sheath 103 and the adjustment foot 104;

[0079] The hydraulic medium 102 is arranged in the accommodating chamber, and as the pressure changes, the hydraulic medium compresses / expands to drive the adjustment foot 104 to move axially in the sheath 103 for leveling.

[0080] The feet for household appliances in this embodiment are based on the principle of hydraulic pressure. Due to the different pressures caused by unevenness, the fluidity of the hydraulic medium makes the adjustment feet automatically perform adaptive adjustments until the feet for household appliances reach balance...

Embodiment 3

[0135] The feet for household appliances in this embodiment include: a hydraulic plate 101, which is provided with a throttling channel inside; a sheath 103, which is fixedly connected with the hydraulic plate 101; an adjustment foot 104, which is arranged in the sheath 103 and can be arranged relative to its axis. to move toward; the hydraulic plate 101, the sheath 103 and the adjustment foot 104 form an accommodating chamber; the flexible accommodating body 108, which contains the hydraulic medium inside, is arranged in the accommodating chamber; under pressure, the flexible accommodating body 108 The expansion and contraction of the containing body 108 drives the adjustment foot 104 to move axially in the sheath 103 for leveling; it also includes a rubber gasket 105, which is fixed on the bottom of the adjustment foot 104, and the bottom of the rubber gasket 105 has designed lines to improve the friction against the ground force and enhance stability.

Abstract

The invention provides a bottom foot for a household appliance and the household appliance. The bottom foot for the household appliance comprises a hydraulic plate, a protecting bush which is fixedlyconnected to the hydraulic plate, an adjusting foot which is arranged in the protecting bush and can axially move relative to the protecting bush and forms a storing chamber with the hydraulic plate and the protecting bush, and a hydraulic medium which is arranged in the storing chamber, wherein the adjusting foot is driven to axially move in the protecting bush to realize levelling by the compressing / expansion of the hydraulic medium as the pressure changes; at least two bottom feet for the household appliance intercommunicate to realize the flowing of the hydraulic medium between the bottomfeet for the household appliance; a liquid flowing channel through which the hydraulic medium flows is arranged in the hydraulic plate; and at least one of the intercommunicated bottom feet for the household appliance is provided with a control device for controlling the liquid flowing channel to open / close. According to the bottom foot for the household appliance, the control device is arrangedon the bottom foot for the household appliance; and the liquid flowing channel of the bottom foot for the household appliance is controlled to connect and disconnect to realize high levelling supporting effect.

Description

technical field [0001] The invention relates to the technical field of support and leveling of household appliances, in particular to a household appliance foot and the household appliance. 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 complete 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 machine by screw...
