Abstract
A portable humidifier including a base defining a reservoir; a storage tank demountably supported by the base and adapted to retain a supply of liquid, the tank defining an orifice communicating with the reservoir; and a valve for controlling liquid flow from the tank into the reservoir through the orifice, the valve adapted to provide a liquid flow rate that maintains a given liquid level in the reservoir. Also included is a wick means comprising supply portions disposed in the reservoir below the given liquid level and evaporation portions disposed above that level, the wick means adapted to provide by capillary action a liquid flow from the supply portions to the evaporation portions; a housing defining an air flow path including the evaporation portions, the housing defining inlet openings and discharge openings; and a blower for producing air flow into the inlet openings, through the evaporation portions, and out of the discharge openings. The combination of a base reservoir and a demountable storage tank enhances the storage volume to unit size of the humidifier.
