Gas burner

Abstract

What is shown is an improved gas burner assembly that is easily adapted to attach to a range top or cooktop, or the floor of the range and can draw air from either above the range top level by external vents or from below range top level through an open style mixing cup. The improved gas burner assembly uses a plurality of flame rings providing the user a wide variety of temperature settings starting from a low intensity simmer to high intensity cooking heat. A gas transfer channel provides a sustaining ignition source. The gas transfer channel has sustaining flame buttons interior to the burner body, and provides the initial ignition for the main flame rings. The gas transfer channel additionally has slots that provide additional sustaining flames for the main flame rings located on the exterior of the burner body. The improved gas burner assembly additionally uses a cover plate of transparent or translucent, heat proof material that allows the user to observe the interior of the burner to which flame rings have ignited. The cover plate also transfers heat from the internal flame rings to the cooking utensil imparting a more uniform transfer of heat to the cooking utensil.
