Description
Technical Field
The invention relates to the technical field of supporting and leveling of household appliances, in particular to a household appliance footing and a household appliance.
Background
The household electrical appliance is generally provided with a leveling device at the bottom of a shell, the household electrical appliance can be placed stably by adjusting the leveling device, and the household electrical appliance can be supported and kept stable after being placed after being leveled.
Taking a washing machine as an example, the bolt footing is generally installed at the bottom of a shell or the whole washing machine in the prior art, the bolt footing comprises a screw rod, a nut gasket and a rubber pad, the nut gasket can rotate up and down on the screw rod, the screw rod can also rotate up and down in a screw hole of a bottom plate of the shell, the height of the washing machine can be adjusted by the length of the screw rod of the bolt footing screwed into the screw hole of the bottom plate, the feet of most washing machines rotate anticlockwise for height adjustment, and rotate clockwise for height reduction, and after the height of the bolt footing is adjusted, the nut gasket which is prevented from loosening is screwed down to keep stable.
The bottom foot of the washing machine realizes the leveling of the washing machine, but needs manual adjustment by a user, and if the washing machine has heavy dead weight or the setting space is narrow, the operation of the user is inconvenient. In addition, the vibration of the washing machine in the long-term working process also acts on the flat bottom of the exchange, so that the support of the washing machine is easy to lose efficacy, and the washing machine is not placed flatly.
For example, the existing 8KG drum washing machine is generally about 80KG, heavy, inconvenient for consumers to adjust, and even if the adjustment is completed, the adjustment of the washing machine cannot be guaranteed to be in the best state, and once the washing machine is not horizontal or has leg weakness problems when the washing machine is used for spin-drying and dewatering by accelerating from 0r/min to about 1400r/min, the washing machine vibrates greatly, and the use comfort of the consumers is greatly influenced.
In addition, vibration caused by the unevenness of the washing machine may loosen the foot screw to move the foot bracket vertically, and such instability may change the horizontal state of the washing machine, resulting in more intense vibration. The vicious circle prolongs the time for the washing machine, the noise becomes bigger and bigger, certain damage is caused to the washing machine, and the service life is shortened.
Therefore, the leveling of the existing washing machine has the problems of time and labor waste and poor precision due to the fact that manual adjustment is needed.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
In order to solve the above problems, a first object of the present invention is to provide a foot for a household appliance, specifically, the following technical solution is adopted:

the hydraulic plate is internally provided with a liquid flow passage, and the hydraulic plate is provided with a connecting hole communicated with the liquid flow passage;
the hydraulic nozzle is arranged on the connecting hole and is used for connecting a hydraulic pipeline;
the sheath is fixedly connected with the hydraulic plate;
the adjusting foot is arranged in the sheath and can move axially relative to the sheath;
an accommodating chamber is formed among the hydraulic plate, the sheath and the adjusting foot;
and the hydraulic medium is arranged in the accommodating cavity, and along with the change of pressure, the hydraulic medium is compressed/expanded and flows in the liquid flow channel and the hydraulic pipeline to drive the adjusting foot to axially move in the sheath for leveling.
Further, the liquid flow channel is a throttling flow channel used for limiting the flow speed of the hydraulic medium, and the diameter of the connecting hole is larger than the aperture of the throttling flow channel.
The flexible accommodating body is arranged in the accommodating cavity, a cavity is formed in the flexible accommodating body, the hydraulic medium is accommodated in the cavity, and the flexible accommodating body deforms along with the flow of the hydraulic medium to drive the adjusting foot to move axially along the sheath for leveling; the flexible containing body comprises an opening part, and the opening part of the flexible containing body is hermetically arranged on the hydraulic plate and is communicated with the liquid flow channel.
Furthermore, a sinking groove is formed in the lower end face of the hydraulic plate, the opening portion of the flexible accommodating body surrounds the sinking groove, and the liquid flow channel is communicated with the sinking groove.
Furthermore, a throttling flow channel is arranged in the hydraulic nozzle, the hydraulic nozzle is installed on the connecting port, and the throttling flow channel in the hydraulic nozzle is communicated with the liquid flow channel and used for limiting the flow speed of a hydraulic medium.
Furthermore, the hydraulic nozzle is in sealing connection with the connecting hole in an interference fit mode.
Further, the connecting hole in set up the internal thread, set up the external screw thread on the connecting end of hydraulic pressure mouth, hydraulic pressure mouth sets up sealed glue or sealing strip with the threaded connection department of connecting hole to carry out the sealed fastening connection between hydraulic pressure mouth and connecting hole.
Furthermore, the hydraulic nozzle and the connecting hole are connected in a sealing and fastening mode through thermal welding or ultrasonic welding.
Furthermore, the upper end of the sheath is flanged outwards to form a mounting plane, and the mounting plane is attached to and fixedly connected with the bottom surface of the hydraulic plate; and avoidance ports for accommodating the hydraulic nozzle are formed in the positions of the mounting plane and the hydraulic plate corresponding to the connecting holes respectively. A second object of the present invention is to provide a household appliance having a foot for a household appliance as described in any of the above.
According to the hydraulic principle, due to different pressures generated by unevenness, the bottom foot for the household appliance automatically adjusts the adaptability by the fluidity of the hydraulic medium until the bottom foot for the household appliance is balanced, and the hydraulic medium stops flowing, so that the automatic leveling is realized.
The hydraulic nozzle and the hydraulic plate are two components which are assembled after being processed respectively, so that the difficulty of processing the liquid flow channel on the hydraulic plate can be reduced, and particularly, the difficulty of processing the liquid flow channel with the throttling function in the hydraulic plate is greatly reduced.
This is mainly because: on one hand, the thickness of the hydraulic plate is small, so that the process of processing a long liquid flow channel in the hydraulic plate is difficult; on the other hand, when the liquid flow channel with the throttling function with the smaller aperture needs to be processed, the difficulty is increased by multiple times, and the yield is lower. Even when the foot for household appliances needs to realize the throttling function of the hydraulic medium, the throttling flow channel can be arranged in the hydraulic nozzle.
