ABSTRACT:
A barbecue cooking device includes a housing having a casing defining a combustion chamber supported centrally therein spaced from the walls of the housing. A heat shield surrounds the combustion casing and is spaced therefrom. A diffuser plate is mounted in the combustion chamber and includes openings in at least a portion thereof for the passage of air under pressure for creating a primary combustion zone. Air is forced against the bottom of the diffuser plate under pressure by an electrically driven fan. The combustion casing has a top open end spaced from the open top end of the housing where a cooking grill is supported. Air also is caused to flow between the combustion casing and the heat shield to supply air to the area at the top of the combustion casing for mixing with heated fuel gas from the primary combustion zone, whereby a secondary combustion zone is created above the combustion chamber and beneath the cooking grill.
