Abstract
A cook-top (10) is provided which includes at least one cooking section (12a) heated by at least one heating element which is activated by function controls (9). It includes at least one detector (20) which detects the presence of a cooking utensil on at least one cooking section (12a), the detector actuating a timing means (22) (24) in order to turn off or to reduce the heating of the cooking section when the utensil has been removed, and to turn on the heating of the cooking section when the utensil is put back on the cooking surface if the absence time has been shorter than a given time. The detector may be responsive (20) (26) to the weight of the utensil and/or the temperature of the heating surface.
