Abstract: A method for controlling a cooking hob including induction coils, wherein a heating process includes time cycles subdivided into time slots. The method includes: setting a requested power for each induction coil to be activated by a user, defining a group of induction coils that have the same requested power, determining a number of time slots given by the number of different requested powers, activating all groups of induction coils to be activated during a first time slot at a same current power for a calculated duration, and activating a part of groups of induction coils to be activated during a further time slot at the same current powers in each time slot for a calculated duration if more than one group of induction coils are defined, so that an average current power of each induction coil within the time cycle corresponds with the requested power for the induction coil.

Abstract: The present invention relates to a household appliance (1), in particular to a cooking hob, which comprises or is connected to an acceleration detection and/or measuring means (11) and a control unit (23) for controlling operating processes. The acceleration detection and/or measuring means (11), which may be an acceleration sensor and particularly a gravity sensor, is adapted for a detection of an acceleration of a section or a reference point of a wall or a panel (3) of the household appliance (1). The household appliance (1) may comprise a user interface (9) for providing information to a user, particularly status information, and/or for receiving input, particularly of control commands or data input, from the user. The acceleration detection and/or measuring means (11) is connected to the control unit (23) and/or, if applicable, to the user interface (9) for an exchange of data, and forms a trigger element for the control unit (23) and/or, if applicable, for the user interface (9). Further, the acceleration detection and/or measuring means (11) is adapted to provide a trigger signal for a control of a function and/or an operating process in the household appliance (1). Further, the present invention also relates to a method for controlling a household appliance (1), in particular a cooking hob. According to the invention, a function and/or an operating process in or of the household appliance (1) is triggered by an acceleration detection and/or measuring means (11), particularly by an acceleration sensor, more particularly by a gravity sensor, as a result of a detection of an acceleration of a section or a reference point of a wall or a panel (3) of the household appliance (1).
