Abstract

PURPOSE:To automatically set a heating time by comparing the change rate of resistance of burning odor sensor with a specified value set in advance when a specified time set in advance has elapsed from the specified cooking start time. CONSTITUTION:If a time elapsing from the start until the change in resistance h1 of temperature detecting element 8 in a device from the initial resistance value becomes 10 is within 11 minutes, a basic heating time TEO is set to 25 minutes. If the change rate h2 of a burning odor sensor 7 from the initial resistance value is not higher than 1 when 11 minutes has elapsed from the start, and if the change rate is not higher than 1.4 when 12 minutes has elapsed from the start, the corrected heating time TE of gratin 12 is set to (25 minutes X0.92). If the change rate h2 of resistance of burning odor sensor 7 is higher than 1.4 and not higher than 2, the corrected heating time TE of gratin 12 is set to (25 minutes X 0.96). If the change rate is higher than 2, the corrected heating time TE of gratin 12 is set to 25 minutes. This device enables automatic setting of heating time in accordance with the type and quantity of object being cooked.
