Alternatively, the driving rod is mounted on the side plate of the housing 10 , and the transmission component is mounted on the side wall of the household appliance body 20 .

The built-in household appliance 1 may include a set of driving components, the driving rods of which are mounted on the bottom plate 12 of the housing 10 , and the transmission components are mounted on the bottom wall 22 of the household appliance body 20 . The built-in household appliance 1 may also include at least two sets of drive assemblies, the drive rods of each set of drive assemblies may be respectively installed on the side plates of the housing 10, and the transmission components are respectively installed on the body 20 of the household appliance. on the side wall. Of course, the driving rods of each group of driving components can also be installed on the bottom plate 12 of the housing 10 , and the transmission components are installed on the bottom wall 22 of the main body 20 of the household appliance. It can be understood that, according to the size of the home appliance body 20 and the casing 10 and the convenience of movement, three or more sets of driving components can be selected.

Of course, the driving rod can also be installed on the bottom wall 22 of the household appliance body 20, and the transmission component is installed on the bottom plate 12 of the housing 10; or, the driving rod can be installed on the household appliance On the side wall of the body 20 , the transmission component is installed on the side plate of the housing 10 .

Preferably, the driving rod is a ball screw, and the ball screw includes a steel ball, a pre-compressor, a reverser and a dust-proof device.

As another embodiment, the driving rod is a sliding rod, the transmission part is a sliding sleeve, and the sliding sleeve is fixedly installed on the household appliance body 20 or the housing 10, and the sliding sleeve is along the The length direction of the slide bar is slidable. At this time, the driving motor of the driving assembly is connected to the sliding sleeve, and is used to drive the sliding sleeve to slide to drive the main body of the household appliance to move.

In some embodiments, four corners of the bottom of the bottom plate 12 are protruded with supporting feet 35 .

In the above solution, by protruding from the four corners of the bottom of the bottom plate 12, there are supporting feet 35, and the supporting feet 35 are in contact with the ground, which can reduce the contact area between the embedded household appliance 1 and the ground, and can Play the effect of shock absorption.

In some embodiments, as shown in FIG. 2 and FIG. 3 , at least one moving wheel is installed on opposite sides of the household appliance body 20 respectively;

Preferably, the moving wheels are moving casters 21 .

Of course, the home appliance body 20 can also choose to set a plurality of moving wheels on opposite sides of the home appliance body 20 according to its actual size and the need to consider the balance of the home appliance body 20 when moving.

It can be understood that the moving wheels may be directional wheels, universal wheels or other wheels capable of moving the home body.

The above-mentioned embedded household appliance 1 of the present invention can be installed in a cabinet body, and the side of the cabinet body is provided with an opening for the entry and exit of the household appliance body.

In some embodiments, the cabinet and the housing are integrated, or the housing is designed as the cabinet;

It should be noted that the cabinet body can be a kitchen cabinet or a bathroom cabinet, etc., or other structures that can accommodate the installation space of household appliances in other households. The washing machine body is a tub assembly capable of performing laundry functions in the washing machine, including an outer tub, an inner tub, a motor driving the rotation of the inner tub, a shock-absorbing module and a frame for supporting the outer tub and the inner tub.

When the user needs the washing machine to move out automatically, the user controls the drive motor to work by using the remote control or pressing the function key set on the washing machine, and drives the screw to rotate so that the nut seat moves forward in a straight line. When the nut seat moves to the second position , and contact with the second stop switch, as shown in Figure 2, at this moment, the washing machine body is moved out in place, and the driving motor is controlled to stop working. After the washing machine is launched, the upper cover of the washing machine can be opened to put in the clothes. After putting in the clothes, the user controls the drive motor to work again by using the remote control or pressing the function key. At this time, the screw rod rotates in the opposite direction, and then the nut seat moves backward in a straight line. When the nut seat moves to the first position, it The first stop switch contacts, as shown in Figure 1, now the washing machine body moves into place, and the control drive motor stops working, and now the washing machine starts to run the washing program.

It is understandable that the household appliance may also be other household appliances such as a coffee machine, a cold drink machine, and a freezer.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form.
