Abstract (en)

[origin: EP0169643A1] Heating apparatus includes four infra-red, quartz-halogen, tubular lamps (6), each including a tungsten filament (8), supported above a generally circular shallow tray (1) formed from an infra-red-reflective ceramic material. The apparatus may be mounted beneath a glass ceramic cook-top (19) to form a hotplate area of a cooking hob. The ceramic tray (1) acts as a good reflector, so that radiation emitted from the lamps (6) in a downward direction is reflected upwardly towards, and transmitted through, the glass ceramic cook-top (19). As an alternative to the tray (1), a substantially flat, infra-red-reflective ceramic sheet, a ceramic sheet profiled around the lamps (6), or respective ceramic troughs below each lamp (6), may be utilised.
