HEATING/COOKING DEVICE

PURPOSE:To cook many kind of dishes in menu with the automatic cooking key by halting the operation of a circulation fan when it has reached a setting temperature in a heating chamber, judging the type of a cooked article based on the output of a gas sensor at that time, and driving a fan accordingly so as to heat the food. CONSTITUTION:A selection key 23 is used to drive an oven fan 16 and a heater 18. The fan 16 and the heater 18 come to a halt at that time when a temperature sensor 25 reaches a preheating temperature. In T seconds, the value V10 of a gas sensor is detected. A cake material 1 is mounted on a heating base 3, when a start key is depressed to start heating. When the temperature sensor 25 detects ta, the fan 16 and the heater 18 come to a halt again. In T seconds, the value of the sensor 15 Vta is detected where V=V1a/Vto is computed. When it is V>=x, it is judged to be a bound cake or a sponge cake with a small surface area where heating is continued at an additional higher temperature. This construction makes it possible to control heating/cooking with higher accuracy with a single key, responding to the type of food.
