Abstract
Abstract A humidifier adapted for mounting on an air conduit to add water vapor to air flowing through the conduit. The humidifier includes a flexible resilient plastic tank for holding water. A plurality of screen discs is rotatably mounted in the tank. Each of the discs has a plurality of holes, which holes are aligned to allow air to flow through the discs. The discs are rotated by a motor to pick up water in the tank and place the water in an air stream. The tank is secured to an air conduit by a frame which has a plurality of fingers which extend through apertures in the tank. Wedges in the fingers hold the tank in position. The tank has a hose connected to its bottom to provide a drain for the tank. A transparent tube is connected to one end of the hose, which tube acts as a sight glass for the tank when the tube is mounted in a stored position and through which the tank may be drained when the tube and hose are lowered. The tank also has a pair of windows near the upper portion thereof to allow inspection of the interior of the tank while the humidifier is in operation.
