Sealed gas burner assembly
First Claim
1. A sealed gas burner assembly of the type including an electrically conductive burner cap having a sidewall provided with a plurality of burner ports and an electrode aperture, means for supplying a primary air/gas mixture to the burner ports, an electrically insulative support member mounted in the electrode aperture and provided with an electrode passageway therethrough, a spark electrode extending through the electrode passageway and completely surrounded by the support member, and the spark electrode including a terminal end portion disposed exteriorly of the support member, wherein the improvement comprises means for maintaining a substantially fluid tight engagement between the support member and the electrode aperture to prevent the primary air/gas mixture from passing through the aperture.

Abstract
A sealed gas burner assembly provides fast spark ignition of the primary air/gas mixture by supporting the electrode in an electrically insulative member that is disposed in a fluid-tight sealing engagement through the electrode aperture of a burner head, whereby ignition is facilitated by providing an ignition port directly adjacent an exterior terminal end portion of the electrode. The burner head has a low profile defined partly by a circumferential curved sidewall which eliminates turbulence in secondary airflow to the burner ports during high burner rates. A venturi tube providing the primary air/gas mixture to the burner and ignition is fully contained within an internal chamber of the burner head. The assembly is detachably secured to the burner opening of a range top through a twist lock engagement therewith, and is also provided with a seal to prevent spillovers from leaking between the assembly and the range top into the burner box.

6. A sealed gas burner assembly comprising:
-
a) a burner head defined by a cap and a base; b) the cap including a vertical sidewall provided with a plurality of burner ports and an electrode aperture formed therein, and a first curved sidewall extending downwardly and outwardly from the vertical sidewall and terminating in a first circumferential edge; c) the base including an annular rim, a second curved sidewall extending downwardly and outwardly from the annular rim and terminating in a second circumferential edge, and a cylindrical sidewall disposed inwardly of the second curved sidewall and extending downwardly from the annular rim, the cylindrical sidewall terminating in a bottom wall provided with a central aperture formed therein; d) the cap and base being secured together at their corresponding circumferential edges to dispose the first and second curved sidewalls in overlying relationship with each other, whereby the cap and base collectively define an internal chamber therebetween; and e) a venturi member for directing a primary air and gas mixture into the internal chamber. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
