Patent ID: 8479721

Claim:
A gas burner for a cooking appliance comprising: a first gases flow passage including an inlet and an outlet, a second gases flow passage including an inlet and an outlet, gases flowing through said outlet of said second gases flow passage flowing in an outlet direction, at least one fuel gas jet configured to supply fuel to said second gases flow passage, a source of oxidizing gases at said inlet of said first gases flow passage, a source of oxidizing gases at said inlet of said second gases flow passage, a flame locator within said second gases flow passage, and spaced upstream from said outlet of said second gases flow passage, and spaced downstream of said inlet of said second gases flow passage, said spacing upstream from said outlet of said second gases flow passage sufficient to shelter a flame, when said burner is at a low power setting, and to prevent the flame from being extinguished by said oxidizing gases in said first gases flow passage, and said outlet of said first gases flow passage proximate to said outlet of said second gases flow passage, and a moveable burner cap extending transversely to said outlet direction of said second gases flow passage, said cap having a first extended operating condition and a second retracted non-operating condition, wherein with said burner cap in said first extended operating condition, said burner cap is spaced downstream from said outlet of said first gases flow passage, and with said burner cap in said second retracted non-operating condition, said burner cap substantially closes said outlet of said first gases flow passage.
