The toaster oven of the present invention includes a housing having an internal heating compartment, an upper heating element and a lower heating element. The upper heating element and the lower heating element are independently controllable between zero power and full power in dependence upon a user-selected operating mode.
1. A toaster oven, comprising:
a housing having an internal heating compartment;
at least one upper heating element adjacent to a top of said heating compartment, said at least one upper heating element being operable at a first wattage between zero power and full power;
at least one lower heating element adjacent to a floor of said heating compartment, said second heating element being operable at a second wattage between zero power and full power;
a user interface for selecting one of a plurality of preset cooking modes to be automatically carried out by said toaster oven; and
a control unit in communication with said upper heating element, said lower heating element and said user interface, said control unit being configured to control said upper heating element and said lower heating element in dependence upon a selected preset cooking mode;
wherein in at least one of said preset cooking modes, said control unit is configured to selectively vary an operational time period for said upper heating element and lower heating element, such that one of said wattage of said upper heating element and lower heating element is selectively varied from above zero wattage to below maximum wattage during a cooking operation; and
wherein within said preset cooking modes, said operational time period and said wattage of said upper heating element are controllable independent of said operational time period and said wattage of said lower heating element by a user through said user interface.
2. The toaster oven of claim 1 , wherein:
said first wattage is the same as said second wattage.
3. The toaster oven of claim 1 , wherein:
said first wattage is different from said second wattage.
4. The toaster oven of claim 1 , wherein:
said first wattage is approximately halfway between zero power and full power; and
said second wattage is full power.
5. The toaster over of claim 1 , wherein:
said second wattage is approximately halfway between zero power and full power; and
said first wattage is full power.
6. The toaster oven of claim 1 , wherein:
said at least one upper heating element is two upper heating elements; and
said at least one lower heating element is two lower heating elements.
7. The toaster over of claim 1 , wherein:
said heating elements are tubular heating elements.
8. A toaster oven, comprising:
a housing having an internal heating compartment;
an upper heating element; and
a lower heating element, said upper heating element and said lower heating element being independently controllable between zero power and full power; and
a user interface for selecting one of a plurality of preset cooking modes and for manually controlling said upper heating element and said lower heating element;
wherein in said preset cooking modes, a control unit of said toaster over is configured to automatically control said upper heating element and said lower heating element according to wattages and operational time periods stored in memory and corresponding to said preset cooking mode;
wherein within said preset cooking modes, said wattages and said operational time periods of said upper heating element and said lower heating element are manually and individually adjustable by a user through said user interface for providing precise control over a cooking operation; and
wherein in at least one of said preset cooking modes at least one of said upper heating element and lower heating element is operable at a first power level selectively varied from above zero wattage to below maximum wattage for a first predetermined period of time, and operable at a second power level for a second predetermined period of time, said second power level being different than said first power level within a common cooking period.
