ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is directed to a burner apparatus and more specifically, to a new and novel burner apparatus that can be used on a gas or electric range to prepare food.
Various heating methods have been used for preparing food and we call attention to those gas and electric ranges that have a plurality of openings in their cook top where they have a gas or electric heating element positioned to heat the contents of a cooking vessel. These openings leave the range or stove interior and their elements at risk. When a spill occurs on such a gas or electric range the liquid or food of the spill can fall into the opening, onto the heating elements and also enter the range or stove interior. On a gas range the spill can extinguish the flame and clog the gas jets. On an electric range the spill can cause damage to the wiring and electrical contacts. Cleaning the elements and the interior of either range is difficult.
Accordingly, there exists a need for a new and novel burner apparatus that can be used with a gas or electric cooking range; that is relatively easy to clean and maintain; that can provide a heating surface that can accommodate various sizes of cooking vessels; that permits the cooking of certain foods without the use of cooking vessels, that is securely positioned on the range surface, to seal and protect the range interior and its elements from spills.
SUMMARY OF THE INVENTION
The present invention is directed to a new and novel burner apparatus for use with gas or electric stoves and ranges. In a preferred embodiment of the invention, the burner apparatus comprises a heating surface and a magnetic means for securing the burner apparatus in position on the cooking stove or range.
In another preferred embodiment of the invention, the burner apparatus comprises a heating element.
In another preferred embodiment of the invention, the burner apparatus comprises more than one heating element.
In another preferred embodiment of the invention the burner apparatus is adapted for use with a gas range.
In another preferred embodiment of the invention the burner apparatus is adapted for use with an electric range.
In another preferred embodiment of the invention, the heating surface of the burner apparatus is substantially smooth and even.
In another preferred embodiment of the invention, the burner apparatus further comprises an upper heating surface having a non-stick material coating.
In another preferred embodiment of the invention, the burner apparatus is formed of ceramic material
In another preferred embodiment of the invention, the burner apparatus further comprises means for preventing spillage from entering the basin of the range.
In another preferred embodiment of the invention, the burner apparatus further comprises means for regulating the temperature of the upper surface of said burner apparatus.
In another preferred embodiment of the invention, the burner apparatus further comprises a metal grid for improving the transfer of heat across the upper surface of said burner apparatus.
In another preferred embodiment of the invention, the burner apparatus is formed of a ceramic material having metal strands, flakes or shavings incorporated in the ceramic material for improving heat transfer throughout the burner apparatus.
A primary object of the present invention therefore, is to provide a new and novel burner apparatus for use with a gas or an electric range.
Another primary object of the present invention is provide a new and novel burner apparatus for use with a gas or an electric range that can provide a heating surface that can accommodate various number and sizes of cooking vessels.
Another primary object of the present invention is to provide a new and novel burner apparatus for use with a gas or an electric range that permits the cooking of certain foods without the use of a cooking vessel.
Another primary object of the present invention is to provide a new and novel burner apparatus for use with a gas or an electric range that is relatively inexpensive to manufacture.
Another primary object of the present invention is to provide a new and novel burner apparatus that is easy to install and use with a gas or an electric range.
Another primary object of the present invention is to provide a new and novel burner apparatus for use with an electric range that can replace the conventional electric burners.
