Abstract
The present invention relates to an induction hob with a number of induction coils (12) on a cooking surface (10) and an apparatus for determining the temperatures on the induction coils (12). The induction coils (12) are arranged on the cooking surface (10) according to a predetermined scheme. At least one temperature sensor (14, 16, 18, 20; 24, 26) is arranged within an intermediate space between two or more induction coils (12). The at least one temperature sensor (14, 16, 18, 20; 24, 26) and the central portions of at least two adjacent induction coils (12) are thermally connected by heat conductor elements (22). The temperature sensors (14, 16, 18, 20; 24, 26) are electrically connected to at least one evaluation circuit for determining the temperatures of the adjacent induction coils (12).
