Abstract

A microwave oven is installed above a cooking counter such as a kitchen stove counter. The microwave oven has its housing covered by an oven case, and incorporates a fan. By driving the fan, the microwave oven can have the hot air generated at the cooking counter inhaled from beneath the oven case and discharged from a front opening. The front opening is formed at the front face of the oven case. An operation display device is provided at the front face of the oven case. By one operation of a predetermined key on the operation display device, the drive of the fan is initiated and then automatically terminated at an elapse of a predetermined time (for example, 10 minutes).
