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).
