Abstract: The present invention relates to a sensor means (11, 35, 49, 71) or module for determining a particularly elastic displacement or deflection or bending of a panel (3), in particular a glass panel, or of a section of a panel or of an insert in relation to the panel (3). The sensor means (11, 35, 49, 71) or module and the panel (3) or said section thereof forming a weighing means, in particular a scale. The sensor means (11, 35, 49, 71) or module is adapted to be integrated in or allocated to a household appliance (1), in particular a cooking hob, more in particular an induction cooking hob, and comprises or is connected to at least one processing and/or interpretation and/or compilation means, preferably for providing a particular high sensor sensitivity and/or evaluation unit accuracy. Further, a household appliance (1) is disclosed which comprises an at least approximately horizontal panel (3), in particular a glass panel. The panel (3) is part of or is in functional connection with a scale for weighing an item (15) placed on the panel (3). Finally, the invention relates to a method for determining the weight of an item (15) on an at least approximately horizontal panel (3) of a household appliance (1), in particular on a top panel (3) of a cooking hob. An acceleration of a panel (3) section or of a panel reference point or reference area, in particular a reference point or a reference area on a panel surface (7), is estimated or determined during a displacement or deflection or bending of the panel section or the panel reference point or reference area due to a placing of the item (15) on the panel.

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).
