Gas burner head with means for evacuating trapped water condensate

Claim 1

In a gas burner head wherein the burner head includes a generally concave circular top portion having a central portion, a peripheral portion, and a corrugated portion therebetween comprising a plurality of circumferentially spaced depressions; wherein the burner head further includes a circular bottom portion having a central portion, a peripheral portion, and a corrugated portion therebetween comprising a plurality of circumferentially spaced depressions; wherein the depressions of the top and bottom portions cooperate to define a plurality of outlet ports for a burner flame; wherein the burner head is positioned below and in axial alignment with the flue of a water heater; and wherein the burner head is susceptible to water dripping into the top portion thereof and accumulating therein, the water being caused by condensation of the water vapor content of the flue gas on the walls of the flue, the improvement comprising means formed by cutting of the peripheral portion of the top portion at one or more of the depressions therein for enabling the accumulated water to flow out of said top portion, and means in the peripheral portion of the bottom portion which cooperate with said means in said peripheral portion of said top portion for preventing said flow of water from adhering to said bottom portion, whereby the burner flame at the outlet ports is not adversely affected by said flow of water, wherein said means formed by cutting of said peripheral portion of said top portion comprises one or more tabs bent downwardly, wherein the diameters of said top portion and said bottom portion are the same, wherein said peripheral portion of said bottom portion comprises a generally flat portion, and wherein said means in said peripheral portion of said bottom portion comprises one or more openings, each said opening being located directly beneath each said tab and spaced therefrom.
