Abstract

Disclosed herein is a cooking system for cooking food, the system including a housing defining a hollow chamber configured to receive a food container. The housing has an upper portion defining an opening to the hollow chamber. A lid is attachable about the upper portion of the housing and is configured to extend across the opening to the hollow chamber. At least one heating element is associated with at least one of said housing and said lid. The cooking system is operable in a plurality of modes including a pressure cooking mode and a dry cooking mode. In the pressure cooking mode, the cooking system is operable as a pressure cooker and in the dry cooking mode, the cooking system is operable as a dry cooker.

Claims

1. A cooking system for cooking food, the system comprising:

a heating element included with said convection lid;

wherein said cooking system operates in a plurality of modes, said plurality of modes including a pressure cooking mode and a dry cooking mode, wherein in said pressure cooking mode the cooking system operates as a pressure cooker and in said dry cooking mode the cooking system operates as a dry cooker.

2. The cooking system of claim 1, further including a food container that is receivable within said hollow chamber wherein said cooking system is operable in said pressure cooking mode when said pressure lid is attached to said upper portion of said housing and seals said open end of said food container.

3. The cooking system of claim 2, wherein said convection lid covers said pressure lid when said pressure lid is attached to said upper portion of said housing and is sealing an opening to said food container.

4. The cooking system of claim 1, wherein convection lid moveably attached to said housing, said convection lid being moveable between a first position that covers an opening to said hollow chamber and a second position where said convection lid does not cover said opening to said hollow chamber.

5. The cooking device of claim 2, wherein said food container includes a food support surface, and food is receivable in said food container in contact with said food support surface in both said pressure cooking mode and said dry cooking mode.

6. The cooking system of claim 1, further including a second heating element being disposed at or below a lower extent of said hollow chamber.

7. The cooking system of claim 2, wherein the cooking system is operable in either said pressure cooking mode and said dry cooking mode without having to remove said food container from the hollow chamber.

8. The cooking system of claim 1, wherein said second lid is coupled to said housing when said cooking system is in said pressure cooking mode.

9. The cooking system of claim 2, further comprising an insert for supporting a food item in said hollow chamber, wherein said insert is positionable within said food container to form an annulus between an inner wall of said food container and an outer wall of said insert.

10. The cooking system of claim 9, wherein said insert further comprises a base and an open end, said base including a plurality of apertures that allow fluid to flow through said base.

11. The cooking system of claim 9, further including a diffuser disposed beneath said base, said diffuser including at least one vane configured to impart rotation to fluid circulating through said plurality of apertures during said dry cooking mode.

12. The cooking system of claim 11, wherein said insert is disposed in said food container, said food container is received in said hollow chamber, and further including a fan with said heating element in said convection lid, said fan being positioned to move heated air relatively downward through said annulus, relatively horizontally across a lower surface of said food container, and relatively upward through said diffuser and said plurality of apertures of said base, wherein said fan is positioned to draw air relatively upward through said insert and through said at least one heating element in said dry cooking mode.

13. The cooking system of claim 12, wherein said food container includes an upward facing lower surface that is curved upward in a direction of an upper opening of said food container, and said diffuser includes downward facing lower surface that is curved or sloped to conform to said upward facing lower surface of said food container.

14. The cooking system of claim 2, wherein said pressure lid abuts said housing about a substantial entirety of said upper surface thereof when said pressure lid is in said closed position, and/or wherein said housing is configured to surround food container around a substantial entirety of at least a portion thereof when said food container is received within said hollow chamber.

16. The cooking system of claim 1, further including an insert positionable within said food container, wherein said insert includes a food support surface with a plurality of apertures that allow fluid to flow therethrough.

21. The cooking system of claim 16, wherein the cooking system is operable in either said wet cooking mode and said dry cooking mode without having to remove said food container or said insert from the hollow chamber.
