Gas burner head

Abstract

A gas burner head assembly characterized by a flame-leading pipe strategically positioned between a burning plate and an igniter to provide a climbing path for the flame. The igniter is a part of a standard gas oven and has a fixed height. The burning plate rests on top of a housing that confines a gas-air mixing chamber. The upper open end of the flame-leading pipe is secured on an upper rim of a peripheral wall of the housing. The lower open end of the flame-leading pipe is aligned to the igniter and the main gas nozzle of a valve module mounted on the oven body. By leading the ignited flame to climb from a lower level located by the igniter to a higher level positioned by the burning plate, the gas burner head effectively eliminates the undesirable ignition obstruction while accommodating the standard gas oven valve assembly and igniter.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to a gas powered burning apparatus and more particularly to a multi-function cooking and broiling gas powered burner. BACKGROUND OF THE INVENTION [0002] Multi-use gas ovens are highly desirable for general purpose cooking, baking, and broiling foodstuff. Unfortunately, standard gas ovens are often limited to serving basic cooking needs and do not provide desirable features such as broiling. A possible way to expand or upgrade a standard gas oven's functionality is to exchange, replace, or retrofit the gas burner head. However, currently there lacks an easy, practical, and viable solution to the problem. [0003] In conventional gas ovens, the igniter and gas injector nozzle disposed on a standard valve has a fixed height. On the other hand, existing gas burner heads generate different heights of burning surface level. The poor height match between the burning surface level and the level located by the igniter would ...

AI Technical Summary

Benefits of technology

[0011] The present invention advantageously eliminates the ignition obstruction caused by height mismatch between a standard gas oven with a fixed igniter and different types of burner heads, especially the infrared burner heads. An important advantage of the present invention is that the elimination of the ignition obstruction is achieved without changing the arrangement, positions, or construction of other standard gas oven components such as the valve assembly and the igniter. The valves, igniters, and gas nozzles are standardized products having a fixed ignition height and fixed position with respect to the body of the burner. Consumers are generally prohibited from changing and modifying these components.

[0012] The gas burner head according to the present invention is compatible with most standard gas ovens and broilers and can be easily installed without hassles. Once installed, the gas burner head enables a user of a standard gas oven to conveniently switch between different uses without having to take the oven apart.

Problems solved by technology

Unfortunately, standard gas ovens are often limited to serving basic cooking needs and do not provide desirable features such as broiling.

However, currently there lacks an easy, practical, and viable solution to the problem.

The poor height match between the burning surface level and the level located by the igniter would obstruct the ignition of the burner, or cause poor flame flare-ups on the upper surface of the burning plate.

This height mismatch is a serious obstacle.
