- 16 - C381.1/M ABSTRACT Title: Microwave Ovens and Methods of Cooking Food A microwave oven has a magnetron for delivering microwave power to the oven cavity, and a fan (36) and electrical resistance heating element (38) for recirculating hot air through the cavity. The oven cooks cakes by subjecting the cakes to a first cooking stage during which hot air but no microwave power is produced, and a second cooking stage during which microwave power is produced but the electrical resistance heating element (38) is not energised, and a third cooking stage during which hot air power is applied and microwave power is produced for a certain proportion of the third cooking stage. The transitions between the stages are determined by the recirculated air temperature as detected by a thermocouple (40) positioned to detect the temperature of the air as the latter leaves the oven cavity.
