[0057] The implementation principle of the embodiment of the present application is:

[0058] When the sealing door 3 needs to be opened, the operator inputs a control signal 1 into the controller 4, and the controller 4 receives the control signal 1 and outputs an execution signal 1 to the execution unit 5. The execution unit 5 receives the execution signal 1, controls the opening of the sealing door 3 and controls the rotation of the support plate 61 at the same time. When the sealing door 3 is opened to a horizontal state, the support plate 61 and the sealing door 3 are perpendicular to each other, thereby achieving the opening of the sealing door 3 and the opening of the support plate 61 at the same time.

[0059] Similarly, when the sealing door 3 needs to be closed, the operator inputs control signal 2 into the controller 4. The controller 4 receives the control signal 2, outputs execution signal 2 to the execution unit 5, and the unit receives the execution signal 2, controls the sealing door 3 to close and controls the support plate 61 to rotate into the receiving groove 31. When the sealing door 3 is in the closed state, the support plate 61 rotates into the receiving groove 31, so that the sealing door 3 is closed and the support plate 61 is stored in the receiving groove 31.

[0060] When the dishwashing frame 2 needs to be pushed out of the dishwashing chamber 11, the controller 4 controls the first power supply unit 8 to energize the first electromagnetic coil 71 in the forward direction, so that the first electromagnetic coil 71 generates the same magnetism as the electromagnetic net 72, pushing the dishwashing frame 2 to move toward the sealing door 3. When the first in-position detection switch 95 detects that the dishwashing frame 2 is completely located on the inner wall of the sealing door 3, the first in-position detection switch 95 outputs a first in-position detection signal to the controller 4, and the controller 4 fixes the dishwashing frame 2 through the limit assembly 9.

[0061] Similarly, when it is necessary to move the dishwashing frame 2 into the dishwashing chamber 11, the controller 4 controls the first power supply unit 8 to reversely energize the first electromagnetic coil 71, so that the first electromagnetic coil 71 generates a magnetism opposite to the magnetism of the electromagnetic net 72, attracting the dishwashing frame 2 to move into the dishwashing chamber 11, and when the second in-position detection switch 96 detects the dishwashing frame 2, it outputs a second in-position detection signal to the controller 4, and the controller 4 fixes the dishwashing frame 2 through the limit assembly 9.

[0062] Since the body 1 is equipped with a GPS module, it is convenient to locate the dishwasher, which is beneficial to achieve the purpose of managing and serving discrete customers.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
