ABSTRACT:
A quartz lamp heater is disclosed for a combined microwave, infrared and convection cooking oven. The quartz infrared lamps have blinds which either direct the infrared rays toward the food for broiling, or towards a rotating heat exchanger/fan, which in turn transfers heat to the air and blows it out and down towards the food. A quarterwave choke is provided to prevent microwaves from exiting the cavity through the power leads to the quartz lamp heaters.
