Unitary gas burner

Abstract

A gas burner and a gas burner assembly for an appliance are provided. The gas burner assembly includes a unitary gas burner comprising a body portion, a cap portion, and a gas conduit portion. A plurality of burner ports is defined in the sidewall of the body portion of the unitary gas burner. A gas burner is also provided. The gas burner comprises a body portion, a cap portion, and a gas conduit portion that are segments of a single piece forming the gas burner.

Description

FIELD OF THE INVENTION[0001]The subject matter of the present disclosure relates generally to a gas burner for the cooktop of an appliance.BACKGROUND OF THE INVENTION[0002]Gas burners commonly are used on the cooktops of household gas cooking appliances, including, e.g., range ovens and cooktops built into cabinetry. Because of, e.g., limitations in traditional manufacturing processes, such burners typically are assembled from several separate pieces, such as a burner body, a cap, and a gas conduit. For consistent burner performance, the tolerances and clearance fits for these pieces generally are small, e.g., gaps in the interface between the burner body and the cap, which is placed on top of the burner body, often must be controlled to less than 0.008 inches. These tolerances are difficult to maintain with typical manufacturing processes, such as, e.g., forging and casting.[0003]Additionally, gas burners commonly are exposed to extremely high temperatures, e.g., between 700° F. an...

AI Technical Summary

Benefits of technology

The present invention provides a gas burner assembly for an appliance, which includes a single-piece gas burner with multiple burner ports and a gas conduit portion. This gas burner assembly also includes an igniter and a gas supply conduit for supplying gas to the gas burner. Additionally, the gas burner assembly includes a gas burner, which has a body portion with a sidewall and a top section, and a cap portion at the top section of the sidewall with multiple burner ports. The gas burner and the gas conduit portion are segments of a single piece. The invention offers improved gas burner performance and control for cook compatibility.

Problems solved by technology

Because of, e.g., limitations in traditional manufacturing processes, such burners typically are assembled from several separate pieces, such as a burner body, a cap, and a gas conduit.

These tolerances are difficult to maintain with typical manufacturing processes, such as, e.g., forging and casting.

Additionally, gas burners commonly are exposed to extremely high temperatures, e.g., between 700° F. and 1100° F., and over time, exposure to such high temperatures can cause the gas burner components to warp.

The expansion and / or deformation of burner components can interfere with the performance of the gas burner by altering how the burner components fit together, specifically with respect to the mating of dissimilar materials.
