Abstract
A cooking appliance including a combustion zone and a cooking zone. The combustion zone has a combustion zone air flow path extending from a combustion zone air inlet to a combustion zone air outlet. The cooking zone overlies the combustion zone, and the cooking zone includes a closed cooking volume having a cooking surface and an openable lid. Combustion products produced in the combustion zone are isolated from the closed cooking volume.
Claims20
A cooking appliance comprising:
- (a) a combustion zone having a combustion zone air flow path extending from a combustion zone air inlet to a combustion zone air outlet;
- and,
- (b) a cooking zone positioned overlying the combustion zone, the cooking zone comprising a closed cooking volume having a cooking surface and an openable lid,
- (c) a chimney in a fixed position relative to the combustion zone and downstream from the combustion zone, the chimney has a chimney air outlet that is provided at an upper end of the chimney and the chimney air outlet is located at an elevation above the closed cooking volume,
- whereby combustion products produced in the combustion zone are isolated from the closed cooking volume;
- and
- wherein the openable lid is moveable between a closed position overlying the cooking surface and an open position in which the cooking surface is uncovered while the chimney remains in the fixed position downstream from the combustion zone, wherein the openable lid is rotatable in an upward direction from the closed position to the open position.

A cooking appliance comprising:
- (a) a combustion zone having a combustion zone air flow path extending from a combustion zone air inlet to a combustion zone air outlet;
- and,
- (b) a cooking zone positioned overlying the combustion zone, the cooking zone comprising a closed cooking volume having a cooking surface and an openable lid,
- whereby combustion products produced in the combustion zone are isolated from the closed cooking volume;
- and
- wherein a chimney is positioned downstream from the combustion zone, the chimney comprises an inner air flow duct and an outer duct spaced from the inner duct, and a chimney air outlet is provided at an upper end of the inner duct of the chimney.

A cooking appliance comprising:
- (a) a combustion zone having a combustion zone air flow path extending from a combustion zone air inlet to a combustion zone air outlet;
- and,
- (b) a cooking zone positioned overlying the combustion zone, the cooking zone comprising a closed cooking volume having a cooking surface and an openable lid,
- whereby combustion products produced in the combustion zone are isolated from the closed cooking volume;
- and
- wherein the combustion zone air inlet has a variable sized inlet cross-sectional flow area and the cooking appliance further comprises an inlet adjustment mechanism which automatically varies the variable sized inlet cross-sectional flow area of the combustion zone air inlet as a temperature in the combustion zone varies.
