Abstract
A grilling arrangement comprises a compartment including two tungsten-halogen lamps mounted adjacent the top of the compartment behind a screen of infra-red-transmissive material. The lamps are emissive of infra-red radiation, which grills food supported on a shelf in the compartment. Each lamp has a reflector, which is preferably parabolic in cross-section, to reflect infra-red radiation from the lamps onto the grilling surface. A control arrangement is also provided to impart oscillatory movement to the reflectors and lamps, so that infra-red radiation from the lamps is swept across the grilling surface, thereby achieving a substantially uniform distribution of intensity of infra-red radiation over the surface over a given length of time.
Claims7
A grilling arrangement including a grilling surface for supporting food to be grilled, a source of infra-red radiation for grilling said food, means for reflecting infra-red radiation generated by said source towards said grilling surface, and power driven means operative during grilling for imparting movement to said reflecting means so that during grilling said reflected radiation is swept across said surface to enhance the uniformity of distribution of intensity of infra-red radiation over said surface over a predetermined length of time, as compared with the degree of said uniformity that would prevail in the absence of said movement of said reflecting means.
