ABSTRACT:
This invention is directed to a method of and apparatus or device for flame switching in order to associate a flame and the energy of the flame with different and distinct energy using systems. The flame switchable gas burning device, when adapted to be mounted or attached within the oven cavity of a gas stove, provides an improved gas stove which can, within the one oven cavity, operate in the broil, bake and self-clean mode without the need for multiple burners or multiple oven cavities and without the need for manually operated baffles or dampers. 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, by the method of establishing a flame in the first direction, providing a source of fresh air directed toward the source portion of the flame and creating a low pressure zone or a negative pressure field in a region proximate to the source portion of the flame and directed in the second direction thereby causing the flame to switch and be established in the second direction.
