Microwave oven with heating chamber temperature detecting circuit |
摘要 |
In a circuit for detecting the heating chamber temperature in a microwave oven, a switching transistor is connected in series or parallel with a heating chamber temperature detecting thermistor. If and when the heating chamber temperature need not be detected, the switching transistor is turned on when the switching transistor and thermistor are connected in parallel and off when the switching transistor and thermistor are connected in series to consequently prevent corrosion of the terminals of such thermistor.
