  • Patent number: 6946631
    Abstract: A browning device for use in a microwave oven. The browning device can include an infrared generator for generating infrared radiation. The browning device being formed such that it has a hollow space. The interior surface of the hollow space facing the microwave oven cavity having an infrared absorbing material for absorbing infrared radiation from an infrared generator. The infrared absorbing material is constructed such that it is able to reach a temperature of 500° C. at which soot is vaporized or ignited. Quartz tubes may be utilized as the infrared generator.
    Type: Grant

  • Patent number: 6448540
    Abstract: A microwave oven for heating foodstuffs, comprising an oven cavity (4), a loading zone for the foodstuffs arranged in the oven cavity, a microwave unit for feeding microwaves to the oven cavity, and a browning device (13) having a radiation means (17) for generating infrared (IR) radiation. The browning device also comprises a reflector (16) adapted to reflect IR radiation essentially towards the loading zone. At least a surface layer of the reflector is made of a non-metallic, reflective and heat-resisting material.
