PURPOSE:To cool a heat emitting component in good performance even when an oven is in service and enable stable use of induction heating by furnishing a blower fan and a wind duct in the oven, and spouting the exhaust air aslant downward from a spout hole. CONSTITUTION:When heating is started by an operational part 3, a control circuit 25 drives an induction heating coil 8 or a heater 22. A heat sink 18 on which a switching element 19 as a heat emitting component is mounted, is cooled by the wind from a suction hole 2 generated by a cooling fan 16. If therein an oven situated below 10 is in service, hot air is exhausted from the exhaust hole 11 being willing to be included in the suction air for the fan 16. Now a blower fan 12 sends the wind to a wind duct 13, and if it is spouted out of a spout hole 14 aslant downward through a louver 15, the exhaust air from the oven 10 is prevented from inclusion in the suction air for the fan 16. Thereby stable induction heating can be made without dropping the cooling performance of the heat emitting component even when the oven is in service. |
