Abstract The rotary drum humidifier is mounted in an opening in the horizontal supply duct of a forced warm air furnace. An annular mounting bracket surrounds the opening on the inside of the duct and has a plurality of spaced apart mounting studs extending through holes provided in the wall and surrounding the opening. The humidifier includes a housing having a bottom wall and upstanding side walls forming a water reservoir, with the side walls being provided with horizontally extending mounting flanges having apertures for receiving the studs which are then provided with nuts. A cylindrical porous drum, motor driven, is rotatably mounted in the housing and is adapted to be wetted by the water in the reservoir. Hinge means are provided along one flange of the housing through which a pair of adjacent mounting studs extend. When the nuts are removed, except for the nuts adjacent the hinge means, the entire humidifier is permitted to swing downwardly whereby the humidifier, drum and housing may be serviced or routinely maintained in a fast and efficient manner. The bottom wall has an opening therein terminating in a downward extending annular rim. A combined tubular and flexible over-flow stem and quick drain tube assembly has one end into which the rim extends. The assembly has two positions, one position being with the stem extending upwardly from the bottom wall of the reservoir whereby excess water can over-flow the stem. In the second position, the combined funnel-shape stem and tube extend downwardly away from the bottom wall of the reservoir to permit the water in the reservoir to drain.
A humidifier apparatus comprising a housing having a water reservoir therein and means for maintaining the water at a substantially constant level in said reservoir, a porous evaporator means rotatably mounted in said housing and adapted to be wetted by the water in said reservoir, the bottom wall of said reservoir having an opening therein terminating in a downwardly extending annular rim, a manually operated combined tubular and flexible non-metallic over-flow stem and quick drain tube assembly in the form of a wide mouthed generally conically shaped vessel which terminates in a tube, with the wide mouth end of said vessel receiving said rim, means securing the vessel of said combined over-flow stem and drain tube assembly of said combined over-flow stem and drain tube assembly to said rim, said assembly having two positions, one position being with the tube telescopically located within said vessel and forming said over-flow stem, with said assembly located within said reservoir and extending upwardly from the bottom wall of said reservoir whereby excess water in said reservoir can over-flow said stem, and a second position being where the vessel and tube are located outside of said reservoir and extend downwardly away from the bottom wall of the reservoir to permit the water in the reservoir to drain through said vessel and tube.
