Offset igniter assembly

Abstract

A gas burner assembly for connection to a source of gas is provided. The gas burner assembly includes a burner body defining an opening therethrough and a generally circular outer periphery. The outer periphery includes a recess therein. The gas burner additionally includes a bracketing unit secured to the burner body and including a igniter holder and at least one igniter being concentric about a vertical axis and positioned within at least one of the recess and the igniter holder. The igniter includes an ignition element that is adjustably positioned to provide an optimal radial distance from the burner body, and wherein the gas burner assembly is configured to operatively accommodate a variety of igniter styles.

Description

BACKGROUND OF THE DISCLOSURE[0001]The following disclosure relates generally to gas burners, and more particularly to ignition elements for igniting the fuel gas on the gas burners. The present disclosure finds particular application in accommodating a variety of ignition elements within a single family of burners.[0002]Traditionally gas burner cook tops include ignition devices that generate a spark to ignite a burner when applicable fuel valves are opened, delivering fuel to the burner. Increasingly, however, the spark ignition devices are being replaced by ceramic hot surface ignition devices to ignite burners more reliably. Rather than relying on a spark, the ceramic hot surface igniter includes an element that generates a sufficient amount of heat to ignite the gas supplied to the burner. The ceramic hot surface igniter is essentially a hot filament and, as opposed to a spark, makes no noise and can be left on constantly such that a user can re-light the flame should it extingu...

Problems solved by technology

Therefore, the optimal location of a hot surface ignition device may not be the same as that needed for a spark electrode, depending on the burner design and other design limitations.

However, having to replace burner parts when changing ignition styles increases the number of parts to manage throughout the production and manufacturing chain, thereby increasing cost and complexity.
