ABSTRACT:
A portable warm air humidifier for delivery to a room a steam air mixture of uniform moisture and at a temperature that does not cause sensation of pain. A steam ejector is used to mix the steam from an evaporation chamber with the air entering the humidifier with the advantage, among others, of eliminating the need for motors and blowers. A difference in the water level between a water supply compartment and the evaporation chamber provides a constant pressure in the evaporation chamber which is necessary to drive generated steam through a steam nozzle communicating with the steam ejector. The dimensions of the steam nozzle are determined in relation with the rate of steam generation in accordance with steam velocity to effectively eliminate or minimize the noise normally associated with the passage of steam through a nozzle. The humidifier may have a filter medium to filter particulates from the air notwithstanding the drop in pressure of the air across the filter medium from the outside to the interior of the humidifier.
