ABSTRACT:
A sheetmetal water tank has spaced vapor ports in its upper end arranged in a circle. An inverted, generally can-shaped shroud, which has an outer diameter smaller than that of the tank, is secured coaxially on the tank with its lower, open end positioned in spaced, near tangential registry with the vapor ports. An electric fan is mounted in the shroud to rotate in a horizontal plane positioned axially inwardly from the lower, open end of the shroud. The fan is controlled by a combination switch-rheostat unit, which is mounted on top of the shroud for operation by a manually rotatable knob.
In use the tank is placed on a heated surface, and its fan is energized to draw fresh air through vent openings in the top of the shroud, and to force the air radially out of the lower end of the shroud and over the vapor ports so that the air entrains moisture for delivery to the surrounding room. When the water level falls below a predetermined level a float-operated switch in the water tank energizes a warning lamp or neon bulb, which is mounted in an opening in the top of the shroud.
