<p>TOUCH CONTROL PANEL FOR INDUCTION HEATING COOk-TOP OF The DISCLOSURE The specification discloses a touch control panel particularly adapted for use with an induction heating cook-top. The panel includes a plate of insulating material such as glass having outer and inner planar surfaces separated by a predetermined thickness. Discrete conductive film areas such as tin oxid? are formed on the outer planar surface of the plate. A printed circuit board includes a plurality of pairs of spaced apart conductive regions formed of copper or the like thereon. Springs are provided to urge the printed circuit board continually against the inner surface of the plate, such that the pairs of conductive regions are disposed in a predetermined symmetrical orientation below the film areas on the outer surface of the plate. Circuitry is connected on the printed circuit board and is coupled to the conductive regions in order to generate electrical signals in response to contact with the film area by a finger of the operator By touching various ones of the film areas formed on the plate, the operator can then control the energization and heating level of the induction heating coils located in the cook-top.</p> |
