  • Patent number: 6121587
    Abstract: In a radiant heating body for a cooking location, in particular in the case of a glass ceramic plate (4), an insulating bottom (2) with an insulating annular rim portion (3) is provided in a pot member (1). A heating element (6) is arranged in an air space (5) above the insulating bottom (2). A safety temperature limiter is provided on the pot member (1). In order to achieve a low degree of switching hysteresis and to avoid an expansion bar regulator, the safety temperature limiter is in the form of a bimetal switch component (8) having a housing (9) which is fixed to the pot member (1) and in which a bimetal element (11) is disposed at the side: towards the air space (5). Provided at the annular rim portion (3) is an opening (20, 24) through which the bimetal element (11) is thermally coupled directly or indirectly to the air space (5).
