<p>PROBLEM TO BE SOLVED: To provide a microwave oven inrush current prevention circuit reducing manufacturing costs, suppressing power consumption, and stabilizing microwave oven operation. SOLUTION: An microwave oven is provided with a fan motor 45 fed with a normal AC voltage from outside, driven, and turning cooling fan, and an inrush resistor 53 set on the input side of a high voltage transformer 60 transforming the normal AC voltage to a predetermined high voltage. Therein, an inrush coil 55 excited by a predetermined low voltage fed via a tap formed at the predetermined position of the fan motor 45, and an inrush relay 57 switching operated by the excitement of the inrush coil 55 are provided.</p> |
