ABSTRACT:

FIELD OF THE INVENTION
The present application relates to burners and more specifically to side burners for grills.
BACKGROUND INFORMATION
Propane cooking grills often include side burners for providing an auxiliary heating surface in addition to the main grilling surface. Conventional side burner assemblies, however, can be quite complex, often requiring large numbers of components. For example, a typical side burner assembly includes a base, bowl, facia, lid, burner, grid, valve, valve bracket, knob, electrode and a variety of screws, nuts and washers. Parts counts of 25 or more are typical. Such complexity leads to substantial assembly time, cost, lost parts and reduced reliability.
Known side burner designs can also be inefficient, failing to deliver a substantial portion of the heat generated to the cooking surface. The heat not delivered to the cooking surface is typically dissipated in the base, raising the temperature of the base.
SUMMARY OF THE INVENTION
The present invention provides a burner, which can be used as a side burner of a grill, that overcomes many problems of conventional side burners.
An exemplary embodiment of a side burner assembly in accordance with the present invention comprises a burner base sub-assembly, a grid and a valve. The burner base sub-assembly includes a base and a burner, with the base and burner being staked together. An exemplary embodiment of the burner has a generally circular configuration with a substantially oval cross section. A fuel feed channel extends radially from a lower portion of the burner. An upper portion of the burner comprises a plurality of apertures arranged about a generally cylindrical protrusion at the top of the burner.
Both the base and the burner may be composed of stamped sheet metal, the base preferably of stainless steel and the burner preferably of aluminized or stainless steel. A dual spark electrode may also be arranged proximate to the burner for ignition.
The burner of the present invention has a substantially reduced parts count, leading to reduced assembly time, reduced cost and improved reliability over known burners.
In addition, the burner of the present invention includes a novel arrangement of flame ports which provides improved heat delivery and distribution to the cooking surface, thus also improving efficiency. Comparisons to known burner arrangements show a 25-30% improvement in efficiency. Heat dissipated in the base is substantially reduced, resulting in a cooler base.
