ABSTRACT:
A utensil detection arrangement for an induction heating apparatus which provides a signal indicative of an off-center position of a cooking utensil supported on a cooking surface which overlies an induction heating coil. The detection arrangement comprises a conductive loop configuration located intermediate the heating coil and the cooking utensil in a plane parallel to the plane of the cooking surface and concentric with respect to the axis of the coil. The conductive loop is linked with the magnetic flux generated by the induction heating coil, which flux changes as a result of the position of a cooking utensil with respect to the axis of the coil and thereby generates a signal which changes in amplitude as a result of utensil position.
