Abstract
A microwave oven delivers microwave power to the oven cavity simultaneously with thermal power provided by a circulation of hot air forced through the cavity by a fan. A temperature sensor in the cavity and timing means monitor the temperature/time variation. If a predetermined maximum temperature (e.g. 250.degree. C.) is reached in the cavity in a predetermined time (e.g. 30 minutes) from commencement of cooking with the oven in a cold condition, the oven automatically switches off to finish the cooking process. Most food items other than large meat or casserole dishes will be cooked within the predetermined time by this method. For larger meat and casserole dishes, where the maximum temperature is reached after the predetermined time, the delivery of microwave power is increased and the delivery of thermal power decreased when the maximum temperature is reached in order to complete cooking of these denser food items.
