  • Microwave oven having a source of infra-red radiation
    Patent number: 4728763
    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.
