Abstract
A cooking device has an exhaust duct () configured and arranged to mix together exhaust air discharged from an opening () at a tip of a nozzle part () and part of cooling air discharged from a cooling fan and guide the mixed exhaust air to discharge it outside of a casing, and an exhaust duct temperature sensor () placed within the exhaust duct () to detect a temperature of an atmosphere inside the exhaust duct at a portion upper than the opening () of the nozzle (). A fan abnormal-stop detection part detects an abnormal stop of the fan when an increment per unit time of an atmosphere temperature inside the exhaust duct () detected by the temperature sensor () during cooking becomes equal to or higher than a first threshold value.
