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.

A humidifier, comprising a water tank having a substantially closed upper end which has therein a plurality of spaced vapor ports, an inverted, generally cup-shaped shroud mounted on said tank centrally thereof, and with its lower, open end spaced above the upper end of said tank, an electric fan mounted to rotate in said shroud coaxially thereof, and in spaced, confronting relation to said upper end of said tank, and means for connecting said fan to an electrical power supply for operation thereby, said shroud having in its upper end a plurality of vent openings, whereby upon energization of the fan air is drawn by the fan inwardly through said vent openings, and is discharged radially outwardly through the lower end of said shroud and across said vapor ports to entrain moisture therefrom, said tank having an outside diameter larger than that of said shroud, and said vapor ports being positioned so that at least portions thereof extend radially outwardly beyond and relative to said lower end of the shroud.
