PURPOSE:To obtain low cost constitution and achieve steadily safety function by a method wherein a monitor switch is provided, one side of the monitor switch is a door switch, the other side of the monitor switch is made OFF by mechanical interlocking with the continuous ON action at the trouble of a cooking switch. CONSTITUTION:A monitor switch 3, a timer contact 4, a door switch 5 and a cooking switch 6 are arranged in order from a power source 1 side between the power source 1 and an electromagnetic wave generating part 2. A safety device is composed by double structure of the door switch 5 and the monitor switch 3 in a main circuit. An electromagnetic wave does not generated from the electromagnetic wave generating part 2 unless the both switches are made ON. The monitor switch 3 is made OFF by mechanical interlocking with the continuous ON action at the trouble of the cooking switch 6. The switch 3 is located rearward of the cooking switch 6, provided to be corresponded to the other end 18 of a supporting body 17 for contacts 14, 15, an acting end 19 thereof is protruded forward. Thereby, a relay switch is not used as a safety device, accordingly, the manufacturing cost can be lowered, further, the electronic oven having excellent safety capability can be obtained. |
