FLAME SWITCHING - A METHOD AND DEVICE THEREFORE AND IMPROVED GAS OVEN USING THE SAME

摘要

ABSTRACT OF THE INVENTIONThis invention is directed to a method of and apparatus or devicefor flame switching in order to associate a flame and the energy of theflame with different and distinct energy using systems. The flameswitchable gas burning device, when adapted to be mounted or attachedwithin the oven cavity of a gas stove, provides an improved gas stovewhich can, within the one oven cavity, operate in the broil, bake andself-clean mode without the need for multiple burners or multiple ovencavities and without the need for manually operated baffles ordampers. The flame is caused to be established in a first direction(typically in the broil mode), to being established in a second direction(typically the bake/self-clean mode), that is the flame is switched, bythe method of establishing a flame in the first direction, providing asource of fresh air directed toward the source portion of the flame andcreating a low pressure zone or a negative pressure field in a regionproximate to the source portion of the flame and directed in the seconddirection thereby causing the flame to switch and be established in thesecond direction.
