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

Induction cooking hob including a cooking area with three or more induction coils and a method for controlling a cooking area

A cooking hob includes at least one heating power transferring element with multiple concentrically arranged windings, one or more heating power energy units for powering the windings, a control unit that controls the heating power energy units, and detection means that determines the coverage of the windings by a cookware item. The control unit balances the heat provided to the cookware item by determining a rescaled electric power for the windings based on power requests and information regarding the coverage of the windings and establishes an operating cycle by determining a duty cycle for one or more windings. The duty cycle defines the activation time of the respective winding and is chosen such that the mean electric power provided to the respective winding within the operating cycle is equal or essentially equal to the rescaled electric power associated with the winding.

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

The invention relates to a hob comprising a transparent or semi-transparent hob plate () and multiple heating elements () arranged below said hob plate (), the hob further comprising illumination means arranged below said hob plate () for providing light markings () at the upper side () of the hob plate (), said light markings () indicating heating zones () associated with the heating elements (), wherein the illumination means comprise a light box () with at least a bottom wall portion () and a pair of side wall portions (), said light box () including one or more lighting elements () for illuminating an interior space () of the light box (), wherein the light box () further comprises an upper portion () being adapted to emit light towards the hob plate () in order to provide said light marking () at the upper side of the hob plate ().

Hob comprising heating zone illumination means

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

Induction hob with induction coils and an apparatus for determining the temperatures on the induction coils

A method for controlling a cooking process on an induction cooking hob (). The method includes setting a temperature value or parameter value corresponding with the temperature by a user. A control unit of the induction cooking hob () sets a maximum power (Pmax) for a corresponding cooking zone, calculates an average slope value (S, S, ASP) of a temperature-time-diagram () of the cooking process, compares the average slope value (S, S, ASP) with a corresponding threshold value (THR, THR, THR), and indicates that the temperature or parameter has obtained the set temperature value or parameter value, respectively, if the average slope value (S, S, ASP) is equal with or smaller than the corresponding threshold value (THR, THR, THR). The method and control unit are provided for controlling a boiling process and a frying process on an induction cooking hob.
