Abstract
The present invention relates to an induction hob with a cooking surface (10) and a number of induction coils (12; 16, 18) within said cooking surface (10). The induction coils (12; 16, 18) are arranged on the cooking surface (10) according to predetermined scheme, so that at least two induction coils (12; 16, 18) can be covered by a standard cooking vessel (14). Each induction coil (12; 16, 18) is connected to at least one induction generator being switched or switchable between a high power and a low power. Each induction generator is separately controllable, so that the induction coils (12; 16, 18) are switched or switchable between the high power and the low power. At least one control unit is provided for controlling the individual induction coils (12; 16, 18) according to a predetermined time pattern. Further, the present invention relates to a corresponding method for controlling the induction hob.
