Abstract
A microwave oven having an improved air outlet and humidity sensor mounting structure includes a body partitioned in its interior into a cooking cavity and a machine room, and a cooling fan installed in the machine room which draws atmospheric air into the cooking cavity while cooling a variety of elements installed in the machine room. In the microwave oven, an air outlet unit discharges air from the cooking cavity, and the humidity sensor senses a cooking atmosphere of the cooking cavity. This microwave oven further comprises a control unit which determines the conditions of food in response to automatically or manually inputted information, and controls the rpm of the cooling fan in response to the determined conditions of the food so as to improve the sensing performance of the humidity sensor.
