Abstract
The components of an electric warm-air humidifier are enclosed in a housing. The components include 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 at a short distance above its open bottom. The chamber bottom and the heating elements are immersed in water contained in the main compartment of an open, removable tray, having a smaller filling compartment communicating with the main compartment. The tray may be removed from the housing for cleaning. The neck of an inverted, removable jug filled with water is placed into the filling compartment, and water fills the tray until its level reaches the lower rim of the jug'"'"'s neck. A blower is mounted above the evaporation chamber and delivers cool air through a duct which communicates with the evaporation chamber via its steam outlet, and humidified air is blown back into the room. The humidifier also contains a control element to prevent damage to the heating element and signal lamps warning an attendant to refill the jug with water. The humidifier may also include a removable drawer.
