ABSTRACT:
An oven is disclosed combining microwave, infrared and convection cooking. The oven includes in addition to a magnetron, a pair of quartz infrared lamps and a rotatable heat exchanger/fan. The quartz infrared lamps have blinds which either direct the infrared rays toward the food for broiling, or towards the rotating heat exchanger/fan, which in turn transfers heat to the air and blows it out and down towards the food. The entire oven is maintained at negative pressure to prevent the escape of hot, smoke-filled air into other parts of the oven or the kitchen.
