Cooking apparatus
First Claim
1. A cooking apparatus comprising:
- a glass-ceramic plate (10),at least one heat radiator arranged beneath the plate,at least one sensor (14) arranged underneath the plate (10), in an area (20) which is shielded from heat radiation (16) from said at least one heat radiator, for measuring the temperature of the plate (10) in this area, and a control device (25) for controlling heating power of said at least one heat radiator in dependence upon signals supplied by the sensor (14),characterized in that;
the at least one heat radiator is a halogen lamp system (12), the glass-ceramic plate (10) is of a composition such that it is highly transparent to halogen lamp radiation and has a degree of absorption of said radiation of approximately ≦
40%, the sensor (14) engages against the underside of the plate (10), the area (20) is shielded from the heat radiation (16) essentially only by a shielding tube (15) enclosing the area (20), and the control device (25) comprises an element (25a) for selecting a nominal temperature.

Abstract
A cooking apparatus comprises a glass-ceramic plate, at least one heat radiator arranged underneath the plate, at least one sensor arranged underneath the plate in an area which is shielded from the heat radiation, for measuring the temperature in this area, and a device for controlling the heating power in dependence upon signals supplied by the sensor. A simple and reliable method of measuring the temperature of the bottom of the cooking vessel can be obtained when, in the cooking apparatus the heat radiator is a halogen lamp system and the hotplate is a ceramic plate which is highly transparent to halogen-lamp radiation and has a degree of absorption of approximately ≦40%, the sensor engages against the underside of the ceramic plate, and the control device comprises an element for selecting a nominal.
