Abstract

The device detects the presence of a food cooking container (9) placed on a cooking hob (1), in particular of glass ceramic and is provided with one heater element such as an electrical resistance element (2, 40, 41, 42), a gas burner (30) or it comprises a halogen lamp. Plates (11, 12) of electrically conducting material associated with the hob (1) and connected to an electrical circuit (13) and being of opposite polarities. The plates acts as plates of a capacitor, i.e. forming a capacitive sensor the capacitance of which changes when the food container is placed on the hob (1) in a position corresponding with the plates (11, 12) the change in capacity of the capacitor being sensed by the electrical circuit (13) which therefore detects the presence of the container (9), to generate a control signal as a result of such detection. This signal is fed to indicator (20) to indicate which heater element has to be operated to heat the container.
