1. A device for controlling a cooking area (4) on a glass-ceramic cooking surface, said device comprising at least one inductive cooking utensil detection device for detecting the presence of a cooking utensil placed on the cooking area and at least one temperature measurement device for measuring a temperature of the glass-ceramic cooking surface in the cooking area;

  • wherein said at least one inductive cooking utensil detection device includes an outer conductor track (1) and an inner conductor track (3), said inner conductor track (3) being nested within said outer conductor track, and said outer conductor track (1) and said inner conductor track (3) are arranged in the glass-ceramic cooking surface within the cooking area; and

    wherein said at least one temperature measurement device comprises said outer conductor track (1) and said inner conductor track (3) of said at least one inductive cooking utensil device, and said outer conductor track (1) includes a conductor track section (2) extending from said outer conductor track (1) into a center part of said cooking area (4), whereby said at least one inductive cooking utensil detection device and said at least one temperature measurement device share said inner conductor (3) and said outer conductor track (1) so as to minimize a total number of device components.
