[0074] In some embodiments, the rotary wheel 13 is a cam 132.
[0075] In some embodiments, the cam 132 comprises a wheel body 1322 rotatably arranged on the cabinet 10, and a driving arm 1324 arranged around the wheel body 1322, the driving arm 1324 being configured to drive the clamping hook structure 12 to disengage from the cabinet 10 and to actuate or release the fourth micro switch 21.
[0076] In the embodiments, the cam 132 comprises a wheel body 1322 and a driving arm 1324. The wheel body 1322 is rotatably installed on the cabinet 10, and the driving arm 1324 is arranged around the wheel body 1322. When the wheel body 1322 rotates to drive the driving arm 1324 to rotate, the hook structure 12 can be driven by the driving arm 1324 to disengage from the cabinet 10, so that the door body 11 can be conveniently opened. The phenomenon of jamming or laboring that may occur in the conventional opening mode of the door body 11 is effectively avoided, and the smoothness of the user experience is greatly improved. Meanwhile, the driving arm 1324 can actuate or release the fourth micro switch 21 when it rotates, that is, the driving arm 1324 is associated with the actuation and release of the fourth micro switch 21, and a close mechanical and electrical linkage mechanism is constructed. When the driving arm 1324 moves to a specific position, the state change of the fourth micro switch 21 can be accurately controlled, so as to coordinate the start and stop of the driving motor 14, so that the motor can be operated or stopped at the right time. Effective control of the opening process of the door body 11 is realized, and the synchronization and coordination between the mechanical action and the electrical control of the whole system are ensured, so that the fault or safety hazard caused by improper cooperation of the two is prevented, and the stability and safety of the overall operation of the microwave oven 1 are further enhanced.
[0077] In some embodiments, optionally, the number of the driving arms 1324 is multiple, and the multiple driving arms 1324 are arranged at intervals along the circumference of the wheel body 1322 (in the direction A indicated in FIG. 12). Figure 1

[0080] In some embodiments, optionally, the microwave oven 1 further comprises an elastic member arranged between the cabinet 10 and the door body 11, for driving the door body 11 to move towards the open position.
[0081] In the embodiments, the elastic member can be arranged between the cabinet 10 and the door body 11 to improve the convenience of opening the door body 11. When the door body 11 of the microwave oven 1 is in the closed state, the elastic member is in a compressed or stretched state and stores a certain elastic potential energy. Once the hook structure 12 releases the locking of the door body 11, the elastic potential energy stored in the elastic member is released and converted into the driving force for driving the door body 11 to move towards the open position. This enables the door body 11 to be automatically opened by a certain angle without the user needing to exert a large opening force, greatly improving the convenience of opening the door body 11. Especially for users with less strength or when both hands are busy with other matters, the user only needs to trigger the door body 11 unlocking mechanism gently, and the door body 11 will be automatically opened by a part under the action of the elastic member, facilitating the user to further completely open the door body 11.

[0088] According to one embodiment of the first aspect of the utility model, the first aspect of the utility model proposes a microwave oven, including control box subassembly, furnace door subassembly (door body), electric interlocking subassembly, cavity subassembly and motor several parts. User sends out signal, control box subassembly's information board (or structural component parts) receives operation signal, power board supplies power for motor. Furnace door subassembly contains the door hook (hook structure) that can slide up and down. Electric interlocking subassembly is equipped with cam, and the cam is divided into a plurality of arms. When the cam rotates, the cam arm (drive arm) moves the door hook (hook structure) upward, and the cam releases the power-off switch that contacts the motor position, controls the motor to disconnect and stops power on. Synchronous interlocking lever A (first rotating arm) releases contact microswitch B (second microswitch), disconnects transformer and stops power on. When the cam rotates and the cam arm moves the door hook upward, interlocking lever B moves upward, disconnects microswitch C, and conveys switch door information. In the process that the cam arm moves the door hook upward, microswitch D is separated from the door hook, and the main circuit power is disconnected.
[0089] Working process:
[0090] Door opening: The door opening key on the control box assembly is depressed, sending a signal to the control board. The control board receives the signal and powers the drive motor. The cam on the motor rotates and the drive arm of the cam moves the door hook upward to disengage the catch. The cam releases the power off switch at the motor home position and the synchronous lever A (first rotating arm) arm releases the micro switch B (second micro switch) contact, shorting the transformer (ensuring no output). During the upward movement of the door hook, the interlock lever B (second rotating arm) moves upward and the interlock lever B clears the micro switch C (third micro switch) contact, signaling the power board that the door is open. During the upward movement of the cam to move the door hook, the micro switch D (first micro switch) is separated from the door hook, breaking the main circuit power.
