Abstract
A smokeless, non-polluting barbecue cooker has a base canister with a centrally located firebox which communicates with a flue to conduct heat, produced from burning fuel within the firebox, upwards to an oven enclosure supported by the base canister. The heat enters the oven enclosure along its central axis. A grill for the support of food stuffs, to be cooked within the oven, prevents the placement of food stuffs directly over the firebox. Thus no drippings from the food can fall onto the hot fuel within the firebox to produce carcinogenic byproducts. A forced air blower provides sufficient oxygen to the firebox so that essentially complete combustion is achieved; and, the barbecue cooker is smokeless in its operation. Various methods for controlling the heat accumulated within the oven enclosure are disclosed.
Claims16
An improved barbecue grill comprising:
- a firebox in which fuel is combusted to generate heat for cooking;
- a flue stack coupled to said firebox for transferring heat from said firebox;
- an enclosure having a removable cover and a floor, said floor having a heat entry coupled to said flue stack for conducting heat from said flue stack into said enclosure;
- a grill placed within said enclosure upon which foods may be placed and supported for cooking above said floor, said grill being free of a support surface for food above said heat entry, whereby drippings from food cooking on said grill will fall free of said heat entry and no drippings will be burned by fuel burning in said fire box.
