1. An apparatus, comprising:
a container having a solid, generally planar heat conducting bottom and a side portion for holding a fluid for boiling; one or more stationary deflector ramps in said container defining one or more vent openings; and said one or more deflector ramps and said one or more vent openings being configured to impart lateral movement to heated fluid currents and/or vapor bubbles moving upwardly away from said heat conducting bottom as to stir said fluid without rotation or other movement of said deflector ramps; wherein said one or more deflector ramps are part of a deflector structure (deflector) that is removably or fixedly disposed in said container, said deflector comprising: a lower side; at least one friction contact point for frictionally engaging said container to prevent movement of said deflector; an inner portion configured for placement proximate to a center of said container; an outer portion configured for placement proximate to a side of said container; plural deflector ramps defining plural radially extending vent openings that provide fluid pathways from said lower side to said upper side, said vent openings extending generally radially outwardly from said inner portion to said outer portion; and each of said deflector ramps including an upper edge and a lower edge, said upper and lower edges being arranged such that, when said deflector is seen in a side view orientation looking in a direction that is normal to one of said lower or upper edges, said lower edge is substantially straight and horizontal and said upper edge is angled relative to said lower edge for at least a portion of its length. |
