Abstract

Disclosed herein is a cooking system for cooking food, the system including a housing having a hollow interior, a lid movable relative to the housing, at least one heating element associated with one of the housing and the lid, wherein the cooking system is operable in a plurality of modes including a conductive cooking mode and a convective cooking mode, wherein in the conductive cooking mode the cooking system is operable as a conductive cooker and in the convective cooking mode the cooking system is operable as a convection cooker.

First claim

What is claimed is:

1. A cooking system for cooking food, the cooking system being functional in a plurality of cooking modes, the cooking system comprising:
a housing having a hollow interior;
at least one lid movable relative to said housing;
at least one heating element associated with one of said housing and said at least one lid;
a rotational air movement device associated with at least one of said housing and said at least one lid,
a controller in communication with said at least one heating element and said rotational air movement device,
wherein during operation of said rotational air movement device, said rotational air movement device is operable by said controller to rotate at a plurality of speeds including a first non-zero rotational speed and a second non-zero rotational speed, said second rotational speed being different than said first rotational speed,
wherein said first rotational speed or said second rotational speed of said rotational air movement device is selectable by said controller in response to a user selectable cooking mode of said plurality of cooking modes, and
wherein said plurality of cooking modes includes a user selectable pressure cooking mode operable at a pressure of at least 40 kPa, wherein said rotational air movement device does not rotate or move air during said pressure cooking mode, and said at least one lid is positionable in a sealing arrangement with said housing during said pressure cooking mode.

2. The cooking system of claim 1 , wherein said first rotational speed is faster than said second rotational speed.

3. The cooking system of claim 1 , wherein said plurality of cooking modes includes a first cooking mode and a second cooking mode separate from said pressure cooking mode, and said rotational air movement device is controlled by said controller to move air through said hollow interior at a first speed in said first cooking mode and moves air through said hollow interior at a second speed in said second cooking mode.

4. The cooking system of claim 3 , wherein in said first cooking mode, said cooking system is operable as at least one of an air fryer mode, a roasting/baking mode, and a broiling mode, and said rotational air movement device moves air at said first rotational speed.

5. The cooking system of claim 4 , wherein in said second cooking mode, said cooking system is operable as a dehydrator, and said rotational air movement device moves air at said second rotational speed.

6. The cooking system of claim 5 , wherein said second rotational speed is half as fast as said first rotational speed.

7. The cooking system of claim 5 , wherein said rotational air movement device rotates at 2650 RPM at said first rotational speed and 1200 RPM at said second rotational speed.

8. The cooking system of claim 5 , wherein when at said second rotational speed said rotational air movement device operates at 50% power relative to operation at said first rotational speed.

9. The cooking system of claim 1 , wherein said rotational air movement device is arranged within said at least one lid.

10. The cooking system of claim 1 , wherein said at least one heating element is arranged within said at least one lid.
