Heating apparatus.

摘要

Heating apparatus consists of a shallow circular tray (1) having a layer (2) of thermally insulative material disposed therewithin and supporting a number of infra-red-emitting, tunsten-halogen lamps (7) on flanges (3,4), beneath a glass ceramic cooktop. A moulding (8) of ceramic fibre material is press-fitted around the ends of the lamps (7) and a thermal limiter (11) is provided to limit the operating termperature of the cooktop. The tray is constructed so as to constrain infrared energy from the lamps to preferentially heat a defined area of the cooktop so as to form a hot plate in said area.
