Abstract

The invention relates to a household appliance, in particular to a household appliance, and aims to solve the problem that feet are easy to wear when the existing household appliance moves. For this purpose, the household appliance comprises a main body, a foot and a lifting wheel, wherein the foot and the lifting wheel are arranged at the bottom of the main body, the lifting wheel can move up and down, the lifting wheel is separated from a supporting surface when the lifting wheel moves upwards, so that the foot can support the main body, and the lifting wheel can support the main body and is separated from the supporting surface when the lifting wheel moves downwards. When the household appliance needs to be fixed, the lifting wheel is close to the main body, the lifting wheel is separated from the supporting surface, the bottom feet contact the supporting surface, and the main body is supported by the bottom feet. When the household appliance needs to move, the lifting wheel is far away from the main body, the lifting wheel contacts the supporting surface, and the feet are separated from the supporting surface, so that the lifting wheel supports the main body. At this time, the main body can move through the lifting wheel, and the footing can not contact with the supporting surface, prevents wearing and tearing the footing.

Description

Household appliance Technical Field The invention relates to a household appliance, in particular to a household appliance. Background The household appliances such as the clothes care machine in the market at present generally have the problem of large volume, and in order to ensure the stability and convenient movement, the bottom is usually provided with a foot and a bottom wheel. Specifically, the bottom of the clothes care machine is generally of a rectangular planar design, bottom wheels are arranged at two corners of the rear side of the rectangular bottom, and feet are arranged at two corners of the front side of the rectangular bottom. The purpose of the design of the bottom wheel and the bottom foot is to realize the stable supporting and moving functions of the equipment at the same time. In the case of normal placement of the device, the two bottom wheels and the two feet can simultaneously contact the ground, providing sufficient support to maintain the stability of the device. However, when it is desired to move the laundry care machine, it is often necessary to push the device from the front side, tilting the front side of the device, so as to achieve the separation of the foot from the ground, by means of two bottom wheels at the rear side. While this design appears to provide both support and mobility, it has drawbacks in practice. In particular, when the front side of the laundry machine is tilted in preparation for movement, it is difficult for the front foot to completely leave the ground due to the heavy weight of the laundry machine. Friction between the foot and the ground is often generated, particularly during pushing, resulting in wear of the foot. Such wear not only affects the service life of the foot, but may also deteriorate its supporting effect after a number of movements of the device. In addition, because the friction force between the foot and the ground is overlarge, larger force needs to be applied when the equipment is pushed, so that the difficulty of the mobile equipment is increased, the equipment can be inclined or unstable, and the safety of a user is influenced. Another problem is that, since the foot is usually made of a hard plastic or a metal wear-resistant material, when the foot is rubbed against the floor repeatedly, it may scratch or damage the floor, especially for wooden or ceramic tile floors. Therefore, there is still room for improvement in the design of the support and movement functions of the laundry care machine in the prior art, how to effectively reduce the contact between the foot and the ground and improve the movement convenience of the device, which is a technical problem to be solved in the industry. The presence of these problems not only reduces the user experience, but also adversely affects the overall service life of the laundry care machine. Accordingly, there is a need in the art for a household appliance to solve the above problems. Disclosure of Invention The invention aims to solve the technical problems, namely, the problem that feet are easy to wear when the existing household appliance moves. In a first aspect, the present invention provides a household appliance comprising a main body, a foot and a lifting wheel, both of which are provided at the bottom of the main body, the lifting wheel being movable up and down; When the lifting wheel moves upwards, the lifting wheel is separated from the supporting surface so that the bottom foot supports the main body; when the lifting wheel moves downwards, the lifting wheel can support the main body, and the bottom feet are separated from the supporting surface. In a specific embodiment of the above household appliance, the household appliance further includes: the driving shaft is rotatably connected to the main body and is connected with a power source, and the power source can drive the driving shaft to rotate; one end of the wheel frame is in transmission connection with the driving shaft, the other end of the wheel frame is connected with the lifting wheel, and the middle part of the wheel frame is in rotary connection with the main body; When the driving shaft rotates, the wheel frame can be driven to swing relative to the main body so as to enable the lifting wheel to move up and down. In a specific embodiment of the above household appliance, a connection groove is provided at one end of the driving shaft, and the connection groove can be connected with a screwdriver or an electric gun. In the specific embodiment of the household appliance, the household appliance further comprises a transmission shaft and a sliding block, wherein the driving shaft is in transmission connection with the transmission shaft, and the driving shaft can drive the transmission shaft to rotate; The sliding block is movably arranged on the transmission shaft, the rotation of the transmission shaft can drive the sliding block to axially move relative to the transmission shaft, and the sliding block is hin
