Abstract

PURPOSE: To enhance safety in door opening time by coupling the operation of a safety switch with the operation of a monitor switch which makes a high-frequency oscillator inoperative when a trouble has occurred in the safety switch.
CONSTITUTION: When a door is open, a door cam 15 parts from a cam lever 8, a safety switch 1 is turned on, and a monitor switch 2 is turned off. With the door closed, the door cam 15 contacts the lever 8 to rotate it in the direction B', so that the switch 2 is turned off and then the switch 1 is turned on. In the case where the opening of the door does not turn off the switch 1 because of a trouble such as fusion of a contact during heating, although it is expected that a latch switch 58 or the like opens a relay contact 56 to break the circuit on the opening of the door, it is possible that the relay contact 56 also is fused, which is dangerous. According to the present invention in such a case the monitor switch 2 turns on to form a short-circuit L-C-D-N, resulting in the melting of a fuse 13 and the breaking of the circuit.
