Abstract
When a hood fan of a microwave oven installed at a high place operates, the air below the microwave oven is guided to a prescribed direction. Namely, the microwave oven may be used as a ventilation fan. When manner of setting of the hood fan is changed, the direction of an air outlet of the fan can be changed. When the hood fan exhausts air to the room, the number of rotation of the hood fan is made lower than when the air is exhausted outside the room.
