PROBLEM TO BE SOLVED: To prevent overload by switching an output regulating means to lower the output of a microwave oven depending on the switching control of a power supply switching means when the microwave oven is operated together with a ventilation motor. SOLUTION: A hood 100 comprises a second switching means 34 and a hood lamp 36 connected in series between first and second normal AC lines 30, 32 and a first switching means 38, a strong/weak selection switching means 40 and a ventilation motor 42 connected in series between the first and second normal AC lines 30, 32. When a microwave oven is operated together with the ventilation motor 42 thereof, a control section 140 switches an output regulating means 51 to lower the output of the microwave oven depending on the switching control of the first or second switching means 38, 34. According to the arrangement, overload can be prevented and a high output microwave oven can be designed. |
