Abstract
A combination convection and steam oven having a three stage atomizer for breaking up supply water prior to vaporization. The atomizer includes a motor-driven fan having an atomizer cup at its hub which revolves with the fan about an axis of rotation. The atomizer cup has rectilinear or concave walls defining pockets having lengthwise slots at their corners. As the atomizer cup is rotated, supply water is fed into the cup so as to impact the inner surfaces and shear as it exits through the slots under centrifugal force, which directs the water through the fan blades. The supply water thereby is broken up by three separate actions prior to vaporization.
