Abstract

Disclosed is a cooking apparatus having a pressurized air entering a heating volume through apertures, pulling the flame from the burner and heating the inner housing, thereby providing radiant heat for cooking food, allowing high temperatures to fully evaporate fats and oils while maintaining excellent fuel efficiency. Cooking apparatus (10) for cooking food by a barbecue grilling method, the apparatus comprising an outer housing (18), an inner housing (12) received within the outer housing defining a heating volume (50), a chamber (20) for pressurised air defined between the outer housing and the inner housing, means to supply pressurised air into the chamber, a plurality of apertures (22) in the inner housing communicating with the chamber to allow pressurised air to exit the chamber into the heating volume, at least one burner (16) located in the inner housing, means to supply a combustible fuel/air mixture to the burner which is separate from the supply of pressurised air to the chamber, and a cooking surface (44) for supporting food wherein the means to supply a combustible fuel/air mixture to the burner comprises a Venturi gas valve linked to a variable speed fan (30).

Claims (6)

CLAIMS :
1. Cooking apparatus for cooking food by a barbecue grilling method, the apparatus comprising an outer housing, an inner housing received within the outer housing defining a heating volume, a chamber for pressurised air defined between the outer housing and the inner housing, means to supply pressurised air into the chamber, a plurality of apertures in the inner housing communicating with the chamber to allow pressurised air to exit the chamber into the heating volume, at least one burner located in the inner housing, means to supply a combustible fuel/air mixture to the burner which is separate from the supply of pressurised air to the chamber, and a cooking surface for supporting food, wherein the means to supply a combustible fuel/air mixture to the burner comprises a Venturi gas valve linked to a variable speed fan.
2. Cooking apparatus as claimed in claim 1, wherein the cooking surface is above the heating volume.
3. Cooking apparatus as claimed in claim 1, further comprising a top wall which is above the heating volume and which is connected to the inner housing, wherein the heating volume is enclosed by the inner housing and the top wall; wherein the cooking surface is located within the heating volume.
4. Cooking apparatus as claimed in claim 1, further comprising a thermostat for controlling the speed of the variable speed fan.
5. Cooking apparatus as claimed in any preceding claim, wherein the inner housing comprises a base and side walls and wherein at least one aperture is provided in each side wall towards one end of the side wall and adjacent a corner where the side wall joins another side wall.
6. Cooking apparatus as claimed in any preceding claim, further comprising a support structure located between the inner housing and the outer housing, configured to support the burner and provide a passage for the supply of the combustible fuel/air mixture to the burner which is separated from the supply of pressurised air to the chamber.
