ABSTRACT:
A heating unit suitable for mounting in a cooking hob includes a circular tray having a layer of thermally-insulative material disposed therein and a peripheral thermally-insulative wall, within which four infra-red lamps, each containing a tungsten filament, are supported. The tray also includes an inner thermally-insulative wall, which encloses the length of each filament. Between the peripheral and inner walls, two conventional, wire-wound heating elements are disposed. The filaments and the elements are energizable independently and/or concurrently, and series and/or parallel combinations of the filaments and the elements may be switched to provide various discrete power outputs.
