Constant humidity evaporative wicking filter humidifier

Abstract

A constant humidity evaporative wicking filter humidifier is disclosed as having a water reservoir tank for holding a supply of water. The water reservoir tank is mounted on a supporting base and is constructed to dispense water as needed into a catch basin formed in the supporting base. A wick element of predetermined height has its lower end positioned within the catch basin for absorbing water up into the wick element by capillary action. A motor driven fan is also mounted on the supporting base relative to the wick element for drawing air with increased humidity through the wick element for discharge from the humidifier into the surrounding atmosphere. The water reservoir tank includes a valve which is selectively responsive to the level of water in the catch basin for dispensing water from the water reservoir tank into the catch basin when the water in the catch basin is below a predetermined level. The fan is driven by a motor that is mounted within a one-piece injection molded motor frame having quick interconnect locking elements for assembly of the motor frame to the supporting base and for quick assembly of other electrical components to the motor frame.
