ABSTRACT:
A humidifier includes a rotating circular base plate driven by a motor through a gear reduction mechanism. A plurality of elongated troughs are mounted in a spaced circular array adjacent a periphery of the base plate, such that outer edges of the troughs are disposed on the surface of a cylinder. The troughs may have a variety of different transverse cross-sectional shapes, such as semi-circular, U-shaped, or V-shaped. A centrally disposed drive shaft extends axially from the base plate and includes a plurality of radially extending circumferentially spaced fins. The rotating base plate and attached troughs are mounted in a housing having an inlet duct and an outlet duct connected in a cold air return duct of a conventional forced air type furnace. A water tank disposed in the bottom of the housing is connected by a float valve to a water supply source such that a constant water level is maintained in the tank. As the base plate rotates, the troughs scoop up water, carry it upwardly into the air flow path, and gradually spill the water to create a waterfall in the air flow path. The radial fins on the drive shaft create turbulence in the air flow path to maximize the amount of moisture entrained in the air flow stream.
