ABSTRACT:
The components of an electric warm-air humidifier are enclosed in a housing resting on a base having a water supply compartment. The housing includes an evaporation chamber in the shape of an inverted cup which has a steam outlet in its top and contains an electric heating element positioned a short distance above its open end. The evaporation chamber and the heating element are immersed in water contained in the water supply compartment. The neck of an inverted, removable, water container filled with water is placed into the water supply compartment and water fills the water supply compartment until its level reaches the lower rim of the water container's neck. The housing and the water container are displaceable from the base so as to provide access to the water supply compartment and the heating element to facilitate cleaning. The humidifier also contains a control element to prevent damage to the heating element when the heating element is not immersed in water and signal lamps warning an attendant to refill the water container with water.
