  • Radiant heating element with a metal foil heat conductor
    Patent number: 6207935
    Abstract: A radiant heating body for a cooking hob has a heating conductor comprising a metal foil and an insulating bottom (12). To make the heating conductor easy to fit and to provide advantageous heat radiation properties the flat geometrical heating conductor pattern is separated out of the metal foil. The pattern forms heating limbs (1) whose large surface is towards the cooking hob and which are held at least at an outer annular rim (13) of the insulating bottom (12).

  • Heat conductor for a cooking plate
    Patent number: 6137090
    Abstract: A heating conductor which can be fitted in a geometrical pattern into a radiant heating body is to be easy to fit and is to have good radiation properties. The heating conductor is separated in the form or partial form of the geometrical pattern out of a metal foil and forms heating limbs (1). In the geometrical pattern there are stabilisation limbs (5) whose width is less than the width of the heating limbs (1) in such a way that they can burn through upon the application of an electrical voltage which is harmless to the heating limbs (1).
