AN INDUCTION COOKING HOB INCLUDING A COOKING AREA WITH THREE OR MORE INDUCTION COILS AND A METHOD FOR CONTROLLING A COOKING AREA

摘要

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 the cooking area (12) is associated with a dedicated induction generator (16) 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). The induction cooking hob (10) comprises a number of pot detection devices for each induction coil (14). 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). The sum of the instant powers (iP) of the activated induction coils (14) within each selected cycle pattern (T1, T2, ..., T11) is equal to the sum of the requested powers (rP) for each used induction coil (14). A cooking mode is activatable by a user, in which the requested power (rP) is automatically changed according to the position of the cooking vessel on the cooking area (12), wherein the requested power (rP) is low, if the cooking vessel is placed on one of the extreme parts of the cooking area (12), the requested power (rP) is high, if the cooking vessel is placed on the other extreme part of the cooking area (12), and the requested power (rP) has an average value, if the cooking vessel is placed on a central portion of the cooking area (12).
