Convection based cooking apparatus with improved draft chimney
View Patent ↗A draft chimney for a convention based apparatus. The draft chimney comprises a flue at least partially defining a path of convection airflow through at least a portion of the interior of a cabinet. The flue passes convection airflow to the exterior of the cabinet.
1. A cooking apparatus comprising:
a cabinet having surfaces that define a cabinet interior;
a heating chamber located within the cabinet interior and including an air inlet;
an indirect cooking chamber located within the cabinet interior and having a substantially horizontal displacement from the heating chamber and including at least three vertically oriented surfaces;
a multi-walled baffle positioned between the heating chamber and cooking chamber wherein at least one wall of the multi-walled baffle defines a wall of a multi-walled reservoir operable to contain a liquid material;
an air outlet defined by at least one surface of the indirect cooking chamber; and
a first air flow path from the air inlet to the air outlet that passes through the indirect cooking chamber.
2. The cooking apparatus of claim 1 , wherein the multi-walled baffle comprises at least one surface that at least partially prevents airflow from the heating chamber from entering the indirect cooking chamber.
3. The cooking apparatus of claim 1 , further comprising:
a cooking grate that resides in the indirect cooking chamber and includes an upper surface and a lower surface; and
the multi-walled baffle comprises at least one surface that at least partially restricts the air flow in the first air flow path from entering the indirect cooking chamber below the lower surface of the cooking grate.
4. The cooking apparatus of claim 3 , wherein the air outlet is defined by a vertical surface of the indirect cooking chamber.
5. The cooking apparatus of claim 3 , wherein the indirect cooking chamber includes an upper surface and an internally defined chimney, and wherein the air outlet is defined by the upper surface of the indirect cooking chamber and the internally defined chimney further defines the first air flow path.
6. The cooking apparatus of claim 1 , wherein the multi-walled baffle comprises a first wall adjacent to the heating chamber and a second wall adjacent to the indirect cooking chamber and defines a space between the first wall and the second wall.
7. The cooking apparatus of claim 6 , wherein at least one surface of the multi-walled baffle prevents liquid that may be located in the indirect cooking chamber from entering into the heating chamber.
8. A cooking apparatus comprising:
a cabinet having surfaces that define a cabinet interior;
a reservoir for holding a liquid material;
a heating chamber located within the cabinet interior and including an air inlet;
an indirect cooking chamber located within the cabinet interior and having a substantially horizontal displacement from the heating chamber and including at least three vertically oriented surfaces;
a multi-walled baffle positioned between the heating chamber and cooking chamber wherein at least one wall of the multi-walled baffle is integral with the reservoir;
an air outlet defined by at least one surface of the indirect cooking chamber; and
an air flow path from the air inlet to the air outlet that passes through the indirect cooking chamber.
