Abstract

Disclosed herein is a cooking system including a housing defining a hollow chamber configured to receive a food container. The housing has an upper portion defining an opening to said hollow chamber. A food container is receivable within said hollow chamber. A lid is attachable about the upper portion of the housing and is configured to extend across said 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 conductive cooking mode and a convective cooking mode. In the conductive cooking mode, the cooking system is operable as a conductive cooker and in said convective cooking mode, the cooking system is operable as a convection cooker. The cooking system is operable in the conductive cooking mode and then the convective cooking mode without removing the food container from said hollow chamber.

Claims

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

a housing defining a hollow chamber configured to receive a food container, said housing having an upper portion defining an opening to said hollow chamber;

a food container receivable within said hollow chamber;

a lid attachable about said upper portion of said housing and configured to extend across said opening to said hollow chamber;

at least one heating element and at least one fan associated with at least one of said housing and said lid;

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;

wherein an annulus is formed between an inner wall of said food container and an outer wall of said insert,

wherein said insert further comprises a base and an open end, said base being said support surface including said plurality of apertures that allow fluid to flow through said base,

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 convective cooking mode;

wherein said cooking system is operable in a plurality of modes that are selectable and input by a user via a user interface, said plurality of cooking modes including a conductive cooking mode and a convective cooking mode, wherein in said conductive cooking mode the cooking system is operable as a conductive cooker and in said convective cooking mode the cooking system is operable as a convection cooker, and

wherein said cooking system is operable in said conductive cooking mode, and then is operable in said convective cooking mode, without having to remove said food container from said hollow chamber.

2. The cooking system of claim 1, wherein said food container is received within said hollow chamber, said food container having a base and an open end, and said lid is attached to said upper portion of said housing and seals said opening to said food container.

3. The cooking system of claim 2, wherein said cooking system is operable in said conductive cooking mode when said lid is attached to said upper portion of said housing and seals said open end of said food container.

4. The cooking system of claim 1, wherein said upper portion of said housing is configured with a bayonet locking feature and said lid is configured with a compatible bayonet locking feature.

5. The cooking system of claim 2, further including a second lid that is adapted to abut said upper portion of said housing and cover said lid when said lid is attached to said upper portion of said housing and seal said open end to said food container.

6. The cooking system of claim 1, further including a second lid moveably attached to said housing, said second lid moveable between a first position that covers an opening to said hollow chamber and a second position where said second lid does not cover said opening to said hollow chamber, wherein said second lid includes a heating element.

7. The cooking system of claim 6, wherein said cooking system is operable in said convective cooking mode when said second lid is in said first position.

8. The cooking system of claim 6, wherein said cooking system is operable in either of said conductive cooking mode and said convective cooking mode when said second lid is in said first position.

9. The cooking system of claim 6, wherein said cooking system is operable in said conductive cooking mode when said second lid is in said first position.

10. The cooking system of claim 1, wherein when in said convective cooking mode the cooking system is operable as at least one of an air fryer, baking/roasting oven, broiler, and dehydrator.

11. The cooking system of claim 6, wherein said at least one heating element is a first heating element and a second heating element, said first heating element being disposed at or below a lower extent of said hollow chamber, and said second heating element being disposed at or above said opening of said hollow chamber.

12. The cooking system of claim 11, wherein said second heating element is disposed in said second lid.

13. The cooking system of claim 11, wherein said second heating element is disposed in said lid, and wherein said at least one fan is also disposed in said lid at or above said opening of said hollow chamber.

14. The cooking system of claim 1, wherein the cooking system is operable in either said conductive cooking mode and said convective cooking mode without having to remove said food container or said insert from the hollow chamber.

15. The cooking system of claim 11, wherein said second lid is coupled to said housing when said cooking system is in said conductive cooking mode.

16. The cooking system of claim 1, further including a diffuser disposed in said hollow chamber, said diffuser including at least one vane configured to impart rotation to fluid circulating through said hollow chamber.

17. The cooking system of claim 1, wherein said insert is positioned in said food container, and both said food container and said insert are received in said hollow chamber, wherein said fan is 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.

18. The cooking system of claim 1, wherein said diffuser is configured to create a vortex of air circulating through said insert.

19. The cooking system of claim 18, wherein said food container includes an upward facing lower surface that is curved upward in a direction of an upper opening of said 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.

20. The cooking system of claim 17, wherein said fan is positioned to draw air relatively upward through said insert and through said at least one heating element in said convective cooking mode.

21. The cooking system of claim 1, wherein said lid abuts said housing about a substantial entirety of said upper surface thereof when said lid is in said closed position.

22. The cooking system of claim 1, wherein said housing is configured to surround said food container around a substantial entirety of at least a portion thereof when said food container is received within said hollow chamber.
