常温度表示装置。 In a power supply circuit for a microwave oven that is equipped with a high-frequency oscillation circuit that has a magnetron on the secondary side of a high-voltage transformer and a control circuit that controls it, each thermal switch that has a bimetal as an over-rise temperature detector is connected to a single-pole double-throw contact. These are connected in series, and each of the thermal switches is connected to the above magnetron and the oven, and each common terminal of each of the above thermal switches is connected to the power supply side of the above power supply circuit. Each movable contact piece is connected to each normally closed terminal on the load side, and each normally open terminal facing each other is connected to the power supply side via each abnormality indicator lamp. An abnormal temperature display device for a microwave oven, characterized in that the movable contact piece is switched to each normally open terminal by the bimetal, and each abnormality indicator lamp is lit to display each abnormal temperature.
