Abstract

A microwave oven has a magnetron (44) for supplying microwave power to the oven cavity and a fan and electrical resistance heating element (32) for supplying a forced flow of recirculating hot air through the oven cavity. To increase the penetration of microwave power into the food, and thereby shorten the cooking time, the magnetron (44) has an operating frequency such as 896 or 915 Megahertz which is lower than is conventionally used in microwave ovens.
