Abstract

Abstract An oven includes two tungsten-halogen lamp units (4, 5) strategically positioned, so that infra-red radiation generated by the units (4, 5) is emitted into the oven cavity to brown or grill food placed in the cavity. The cavity also includes, in one embodiment, an infra-red-reflective support (19, 20, 21) for reflecting infra-red radiation emitted from the lamp units (4, 5) onto the underside of the food. In another embodiment, the support includes a heat transfer medium for absorbing infra-red radiation from the lamp units (4, 5) to produce heat and convey the heat to the underside of the food for browning. The oven may include a source of microwave energy and the support may have a microwave absorbent coating, which produces heat for browning the underside of the food.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 94 words
(1) An oven including at least one tungsten-halogen lamp (9) emissive of infra-red radiation for browning or grilling food (12) placed in the oven cavity (1), said at least one lamp (9) being positioned to brown or grill predominantly regions of said food (12) directly exposed to infra-red radiation from said at least one lamp (9), characterised in that said cavity (1) includes means (19, 20, 21; 23, 24) for utilising infra-red radiation from said at least one lamp (9) to brown or grill regions of said food (12) obscured from said direct exposure.
Claim 2
Dependent Claim 41 words
(2) An oven is claimed in claim 1 wherein said means (19, 20, 21; 23, 24) for utilising infra-red radiation from said at least one lamp (9) consists of reflective means (21) for reflecting the infra-red radiation towards said obscured regions.
Claim 3
Dependent Claim 46 words
(3) An oven as claimed in claim 1 wherein said means (19, 20, 21; 23, 24) for utilising infra-red radiation from said at least one lamp (9) includes means (24) for absorbing heat from said infra-red radiation and for conveying said heat to said obscured regions.
Claim 4
Dependent Claim 50 words
(4) An oven as claimed in any preceding claim and including a turntable (2) in said cavity (1) for rotating said food (12) and said means (19, 20, 21; 23, 24) for utilising infra-red radiation from said at least one lamp (9) relative to said at least one lamp (9).
Claim 5
Dependent Claim 26 words
(5) An oven as claimed in any preceding claim and including a source of microwave energy for cooking food (12) placed in said oven cavity (1).
Claim 6
Dependent Claim 26 words
(6) An oven as claimed in any preceding claim and including a radiant resistive heating element for cooking food (12) placed in said oven cavity (1).
Claim 7
Dependent Claim 94 words
(7) An oven including a source of microwave energy for cooking food (12) placed in the oven cavity (1) and means (9) emissive infra-red radiation for browning said food (12), said infra-red-emissive means (9) being positioned to brown predominantly regions of said food (12) directly exposed to infra-red radiation from said infra-red-emissive means (9), characterised in that said oven includes support means for supporting said food (12), said support means being provided with a coating absorbent of microwave energy to generate heat for browning regions of said food (12) obscured from said direct exposure.
