Abstract
A grilling compartment includes two tungsten-halogen lamps emissive of infra-red radiation and separated from a grilling area by a ceramic protective screen. Infra-red radiation emitted by the lamps passes through the protective screen to irradiate the grilling area to grill food placed therein. A metallic mesh screen is also provided between the lamps and the grilling area, only in close proximity to the lamps and configured to provide a substantially uniform distribution of intensity of infra-red radiation over substantially the whole of the grilling area.
Claims10
An apparatus for grilling or browning food, the apparatus comprising a compartment having a region in which food to be grilled or browned can be placed;
- at least one infra-red emissive lamp having a longitudinal axis and being positioned to heat said region and screening means located between said lamp and said region and being effective to provide a substantially uniform distribution of heat in said region, wherein the screening means comprises a first sheet of a metallic mesh material arranged lengthwise with respect to the lamp and a second sheet of a metallic mesh material adjacent to said first sheet of a metallic mesh material, the second sheet being shorter than, and arranged centrally with respect to the ends of, said first sheet, the screening means being located in sufficiently close proximity to said at least one lamp as to absorb radiation produced by the lamp and re-radiate said radiation at a wavelength which is greater than that produced by the lamp and is more conducive to browning or grilling food.
An apparatus for grilling or browning food, the apparatus comprising a compartment having a region in which food to be grilled or browned can be placed;
- at least one infra-red emissive lamp having a longitudinal axis and being positioned to heat said region and screening means located between said lamp and said region and being effective to provide a substantially uniform distribution of heat in said region, wherein the screening means comprises a sheet of a metallic material having a plurality of apertures, the apertures having progressively different sizes and or spacings depending on the relative transverse distances of the apertures from the longitudinal axis of the lamp, and
- the screening means being located in sufficiently close proximity to said lamp as to absorb radiation produced by the lamp and re-radiate said radiation at a wavelength which is greater than that produced by the lamp and is more conductive to browning or grilling food.
