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.
