Abstract

A cooking system positionable on a support surface includes a housing having a hollow chamber including an internal cooking chamber for receiving a food item, at least one radiative heating element arranged within the hollow interior and operable to heat said cooking chamber and a convection heater disposed within the hollow chamber and operable to heat the cooking chamber. The cooking system is operable in a convection cooking mode and during the convection cooking mode, the at least one radiative heating element is selectively energized.

Claims (26)

1. A cooking system positionable on a support surface, the cooking system comprising:

a housing having a hollow interior including an internal cooking chamber for receiving a food item, the interior of the housing having a ceiling, a floor, and a height extending between the ceiling and the floor;

at least one radiative heating element arranged within the hollow interior and operable to heat the cooking chamber;

a fan shroud mounted within the hollow interior, the fan shroud forming a partition that separates the cooking chamber from a convection chamber, the convection chamber being in fluid communication with the cooking chamber;

an air movement device; and

a convection heater disposed within the convection chamber and operable to heat an air flow moved by the air movement device;

wherein the cooking system is operable in a convection cooking mode, and during the convection cooking mode the at least one radiative heating element is selectively energized;

characterized in that openings are formed within the fan shroud at respective sides of the fan shroud, the openings extending generally over a full height of the fan shroud between the ceiling and the floor of the interior of the housing, and the air movement device is arranged to force the air flow out from the convection chamber through the openings, evenly over the height of the interior of the housing between the ceiling and the floor.

2. The cooking system of claim 1 , wherein a cooking cycle of said convection cooking mode includes at least one convection cooking segment during which said convection heater is energized, and at least one pulsing segment during which said at least one radiative heating element is energized.

3. The cooking system of claim 2 , wherein said convection heater includes a convective heating element, and during said at least one pulsing segment, said convective heating element is de-energized.

4. The cooking system of claim 2 , wherein the convection heater includes a convective heating element, and during the at least one pulsing segment the air movement device is energized, while the convective heating element is de-energized.

5. The cooking system of claim 2 , wherein during said at least one pulsing segment, a power provided to said at least one radiative heating element is less than a full power associated with operation of said at least one radiative heating element.

6. The cooking system of claim 5 , wherein during the at least one pulsing segment, the at least one radiative heating element is operated at 50% of the full power.

7. The cooking system of claim 2 , wherein a time of said at least one pulsing segment is shorter than a time of said at least one convection cooking segment.

8. The cooking system of claim 2 , wherein said at least one pulsing segment occurs at a predetermined interval within said cooking cycle.

9. The cooking system of claim 2 , wherein said at least one pulsing segment is initiated in response to a detection of a sensed condition.

10. The cooking system of claim 9 , wherein said sensed condition includes accumulation of a food byproduct on said at least one radiative heating element.

11. The cooking system of claim 2 , wherein a power delivered to the at least one radiative heating element during a pulsing segment is less than a power delivered to the convection heater during the convection cooking segment.

12. The cooking system of claim 2 , wherein a time of said pulsing segment is less than a time of said convection cooking segment.

13. The cooking system of claim 12 , wherein the convection cooking segment is three times as long as a pulsing segment.

14. The cooking system of claim 1 , wherein said at least one radiative heating element includes a first radiative heating element arranged adjacent the ceiling of said cooking chamber and a second radiative heating element arranged adjacent the floor of said cooking chamber.

15. The cooking system of claim 14 , wherein during said convection cooking mode, said second radiative heating element is selectively energized to clean said second radiative heating element.

16. The cooking system of claim 14 , wherein during said convection cooking mode, both said first radiative heating element and said second radiative heating element are selectively energized to clean said second radiative heating element.

17. The cooking system of claim 1 , wherein the cooking system is operable in a radiative cooking mode.

18. The cooking system of claim 17 , wherein in the radiative cooking mode, only the at least one radiative heating element is energized.

19. The cooking system of claim 1 , wherein the cooking system has a maximum power of 1800 W.
