As shown in fig. 6, the control method is suitable for the kitchen device, and when the door needs to be opened after the kitchen device is operated, the control method further includes:

controlling the electromagnet to be in a reverse electrifying state so that the electromagnet applies repulsive force to the permanent magnet;

controlling a driving device of the kitchen equipment to start so as to drive the door body to rotate towards a direction far away from the machine body;

wherein, in the rotating process of the door body, the potential state of the proximity switch is detected;

when the proximity switch is detected to be in a continuous low potential state within a third preset time, judging that the door body is in an opening state; otherwise, the door body is prompted to have a door opening fault.

Like this, when needs are opened the door automatically, control module control electro-magnet is in reverse circular telegram state to make the effort between the door body and the fuselage less, and then make drive arrangement's start-up easier, laborsaving, do not receive the electromagnetic force influence.

Specifically, the control method in the present embodiment further includes an automatic door opening function for the kitchen appliance. After the kitchen equipment is operated, a user presses a door opening key, the control module controls the electromagnet to be in a reverse power-on state, the electromagnet applies repulsive force to the permanent magnet, the acting force between the electromagnet and the permanent magnet is the resultant force of the repulsive force applied by the electromagnet to the permanent magnet and the magnetic attraction force applied by the permanent magnet to the electromagnet, and the two acting forces are opposite in direction, so that the door body and the machine body can be separated more easily. And then, starting the driving device, wherein the driving device drives the door body to rotate towards the direction far away from the machine body through the transmission assembly so as to realize the door opening action. And in the rotating process of the door body, detecting the potential state of the proximity switch in real time, and judging that the door body and the machine body are not closed any more when detecting that the proximity switch is in a continuous low potential state (the proximity switch is in a non-electrified state) within a third preset time, so that the door opening action is completed, and the automatic door opening is realized. If the proximity switch is detected to be in a continuous high potential state (the proximity switch is in a power-on state) within a third preset time, the door opening fault of the door body is judged, the control module controls the alarm device to send out a third alarm signal to prompt a user that the door body is in the door opening fault, and the user maintains the door body after receiving the third alarm signal. Wherein the third preset time can be adjusted according to the size or specification of the kitchen equipment.

The manner of opening the door of the kitchen appliance is not limited to this. In other embodiments not shown in the drawings, after the kitchen equipment is operated, a user presses a door opening key, the control module controls the electromagnet to be in a reverse power-on state, the electromagnet applies repulsive force to the permanent magnet, the door body is bounced to open the first gap, and the user can directly pull open the door body, so that semi-automatic door opening is achieved.

Optionally, the transmission assembly is pneumatic-hydraulic, or gear-driven, or belt-driven, or rail-driven, or pulley-driven.

As shown in fig. 7, the control method further includes:

detecting the power-on state of the kitchen equipment in the operation process of the kitchen equipment;

and when detecting that the kitchen equipment is in the power-on state again after the power is off, continuously executing the step of detecting whether the door body and the machine body are closed or not.

Specifically, the control method in this embodiment further includes a power-off restart function. Kitchen equipment is dish washer, the washing module of dish washer includes a plurality of sub-cleaning module that carry out in proper order according to time sequence, in the in-process of washing module execution washing action, real-time detection kitchen equipment's on-state, if dish washer is in the on-state again after the outage when carrying out one of them sub-cleaning module of dish washer, continue to carry out and detect the door body and whether closed step of fuselage, detect proximity switch's on-state promptly, if proximity switch circular telegram, then proximity switch is in the high potential state, then judge that the door body is closed mutually with the fuselage. If the proximity switch is detected to be not electrified, the proximity switch is in a low-potential state, the door body and the machine body are judged not to be closed, and the control module controls the alarm device to generate a first alarm signal to prompt that the door body and the machine body are not closed. Meanwhile, the control module controls the execution assembly to drive the door body to close the door so as to realize the automatic door closing action of the kitchen equipment. And after the door body and the machine body are judged to be closed, detecting the potential state of a pressure switch arranged on the machine body, and prompting the door body to have a door closing fault when detecting that the pressure switch is in a continuous low potential state within a second preset time. If the pressure switch is detected to be in a continuous high potential state within the second preset time, the door body and the machine body are closed completely, and the dish washing machine executes the sub-cleaning module executed when the main power supply is disconnected again.
