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 movable relative to the housing. The lid contacts the housing in a closed position about the upper portion of the housing to close 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 cooking 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 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 first lid movable relative to said housing, said first lid contacting said housing in a closed position about said upper portion of said housing to close said opening to said hollow chamber;

a second lid movable relative to said housing, said second lid contacting said housing in a closed position about said upper portion of said housing to close said opening to said hollow chamber;

a heating element included with said first lid;

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

wherein said second lid is attachable to said housing in a locked arrangement during said pressure mode.

2. The cooking system of claim 1, wherein said cooking system is operable in either of said pressure cooking mode and said dry cooking mode when said first lid is in said closed position.

3. The cooking system of claim 1, wherein said cooking system is operable in said pressure cooking mode when said first lid is not in said closed position, and wherein said cooking system is operable in said dry cooking mode when said lid is in said closed position.

4. The cooking system of claim 1, further including an additional heating element disposed at or below a lower extent of said hollow chamber.

5. The cooking system of claim 1, further including a fan disposed in said first lid.

6. The cooking system of claim 1, wherein the system is operable in said pressure cooking mode and then said dry cooking mode without having to remove said food container from the hollow chamber.

7. The cooking system of claim 6, wherein said second lid is attachable to said housing to seal an opening to said opening to said food container when said food container is received in said hollow chamber.

8. The cooking system of claim 7, wherein said second lid is attachable to said housing to seal said opening to said food container when said first lid is not in said closed position.

9. The cooking system of claim 1, further including an insert for supporting a food item in said food container, said insert being 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 10, 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, further including a fan disposed with said at least one heating element in said first 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 when said insert is positioned in said food container, said diffuser is disposed beneath said base, and said food container is received within said hollow chamber, and wherein said fan is positioned to draw air relatively upward through said insert and through said at least one heating element associated with said lid.

13. The cooking system of claim 11, 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 a 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 1, wherein said first lid abuts said housing about an entirety of said upper surface thereof when said first lid is in said closed position, and wherein said housing is configured to surround said food container around an entirety of at least a portion thereof when said food container is received within said hollow chamber.

15. The cooking system of claim 1, wherein said lid remains attached to said housing while being movable from said closed position to an open position.
