Abstract
Ranges which include mounting systems for securing the heating elements so that the heating elements are maintained against an underside surface of the glass panel with a substantially constant force over a broad temperature range are described. In one embodiment, the cooktop includes a frame having an opening for receiving the glass panel. Flanges extend into the opening from the frame and support the panel in the opening. A metal plate is secured to an underside surface of the glass panel, and the plate includes a plurality of radiant heating element openings. The mounting system includes coil springs, or other types of springs, for engaging to the plate and to the radiant heating elements for positioning the radiant heating elements within the radiant heating element openings and against the glass panel. Various alternative embodiments of the above described mounting system are also described.
