1. A draft chimney for a convection based apparatus, said convection based apparatus having a cabinet defining a cabinet interior and including a hood and a lower container, said draft chimney at least partially defining a path of convection airflow through at least a portion of the cabinet interior, said draft chimney passing convection airflow from said cabinet; andsaid cabinet being operable to open, thereby exposeing said cabinet interior and separating said draft chimney into at least two portions at least one portion of said draft chimney remaining within said lower container of said cabinet interior. 2. The draft chimney of claim 1 wherein said path communicates with the exterior of the cabinet at an end of said path. 3. The draft chimney of claim 1 wherein said draft chimney is entirely defined within the cabinet. 4. The draft chimney of claim 1 wherein the length of said draft chimney in the direction of airflow is longer than the width of said draft chimney. 5. The draft chimney of claim 1 wherein said draft chimney is prismatic and at least partially defined by an interior surface of the cabinet. 6. The draft chimney of claim 1 wherein said draft chimney includes opposing first and second openings, said first opening communicating with the cabinet interior and at least being partially defined by at least a portion of an interior surface of the cabinet. 7. The draft chimney of claim 1, wherein said first opening is at least partially defined by at least a portion of an interior bottom surface of the cabinet. 8. The draft chimney of claim 1 wherein said first opening is at least partially defined by the entire width of an interior bottom surface of the cabinet. 9. A convection cooking apparatus comprising:a cabinet having surfaces that define a cabinet interior and including a hood and a lower container; anda draft chimney for creating airflow through the interior of the cabinet, said drafting chimney at least partially defining an airflow path through at least a portion of the cabinet interior, wherein said cabinet being operable to open, thereby exposing said cabinet interior and separating said drafting chimney into at least two portions. 10. The apparatus of claim 9 wherein said path communicates with the exterior of said cabinet at an end of said path. 11. The apparatus of claim 9 wherein said drafting chimney is entirely defined within said cabinet. 12. The apparatus of claim 9 wherein said draft chimney comprises an elongated conduit defining a first opening and a second opening on opposing ends of said elongated conduit, said first opening communicating with said interior of said cabinet. 13. The apparatus of claim 12 wherein said elongated conduit is substantially vertically oriented. 14. The apparatus of claim 12 wherein the length of said draft chimney in the direction of airflow is longer than the width of said draft chimney. 15. The apparatus of claim 12 wherein said first opening communicates with the cabinet interior and is at least partially defined by at least a portion of one of the interior surfaces of said cabinet. 16. The apparatus of claim 12 wherein said first opening is at least partially defined by at least a portion of an interior bottom surface of the cabinet. 17. The draft chimney of claim 12 wherein said fist opening is at least partially defined by the entire width of an interior bottom surface of the cabinet. 18. The apparatus of claim 12 wherein said draft chimney is prismatic and at least partially defined by one of the interior surfaces of the cabinet. 19. The apparatus of claim 12 wherein a first portion of said draft chimney is substantially contained within an upper portion of the cabinet interior and a second portion of said draft chimney is substantially contained within a lower portion of the cabinet interior.
