Abstract
The present invention relates to an induction cooking hob (10) including at least one cooking area (12), wherein the cooking area (12) comprises at least three induction coils (14). The induction coils (14) of at least one cooking area (12) are arranged side-by-side and in series. Each induction coil (14) of at least one cooking area (12) has an elongated shape. The longitudinal axes of the induction coils (14) within one cooking area (12) are arranged in parallel. Each induction coil (14) of 10 the cooking area (12) is associated with a dedicated induction generator (16). The induction generators (16) are connected or connectable to at least one current line (18). The induction generators (16) are connected to and controlled or controllable by at least one control unit (20). Requested powers (rP) for each used induction generator (16) are adjusted or adjustable independent from each other by a user interface (22). Instant powers (iP) of the induction generators (16) within a cycle pattern (T1, T2, . . . , T11) are controlled or controllable independent from each other by the control unit (20). Further, the present invention relates to a method for controlling a cooking area.
