Drainless humidifier with water level sensing

摘要

A housing is permanently connected to a water supply of a building and includes an evaporative water panel allowing water to flow downwardly and wick upwardly. A circulating device is provided for directing air from the building through the water panel. A reservoir is positioned in the housing for supporting the water panel and holding excess water deposited from the water panel. A water distributor is supplied for moving water from the water supply to a top of the water panel. A water control arrangement is responsive to the water level therein for automatically controlling the flow of water to the water panel to provide a desired humidity level in the building.
