Abstract: An oven includes two tungsten-halogen lamp units strategically positioned, so that infra-red radiation generated by the units is emitted into the oven cavity to brown or grill food placed in the cavity. The cavity also includes, in one embodiment, an infra-red-reflective support for reflecting infra-red radiation emitted from the lamp units onto the underside of the food. In another embodiment, the support includes a heat transfer medium for absorbing infra-red radiation from the lamp units to produce heat and convey the heat to the underside of the food for browning. The oven may include a source of microwave energy and the support may have a microwave absorbent coating, which produces heat for browning the underside of the food.

Abstract: A microwave oven consists of an oven cavity containing a turntable, a source of microwave energy and a waveguide for directing microwave energy into the oven cavity. Two lamp units accommodate tungsten-halogen lamps for browning food cooked by the microwave energy. To inhibit arcing through the lamps due to exposure to the microwave energy, support coils supporting the filament of each lamp are each formed from an incomplete turn of the coil to inhibit arcing between adjacent regions thereof. Other modifications to the lamps and/or the units may also be provided to protect the lamps from exposure to the microwave energy.
