Abstract
A humidifier unit with a water supply reservoir, a media unit which passes through the reservoir and picks up moisture, a motor and fan unit together with drive mechanism for rotating the media unit and for blowing air through the media unit and into the surrounding area, and a removable, refillable liquid water treatment dispenser. As depicted, the humidifier is a console room humidifier with the water reservoir accessible from the rear. The removable dispenser is an auxiliary unit consisting of an elongate bottle, the cap of which carries a spring biased poppet valve with a projecting stem. The bottle is inverted and received through an opening in the top wall of the humidifier with its valve operating stem resting on an abutment above a flow passage funnel unit mounted on structure within the humidifier above the water reservoir. The dispenser, when in place, can be pressed down against the biasing force of the spring biased poppet valve, causing the valve to open and dispense a selected amount of treatment fluid such as an anti-liming composition into the water reservoir.
