Abstract
A centrifugal humidifier having a rotatable body for propelling water outwardly on to an impingement surface that brake up the propelled water into droplets which are then entrained in a stream of air and discharged to the surroundings, wherein the impingement surface has a multiplicity of sawtooth ridges oriented with the more gradually inclined sides facing toward the direction from which the water is propelled by the rotatable body which promotes breaking up the water into finer droplets.
Claims6
A centrifugal humidifier, comprising:
- at least one body rotatable on an axis for propelling supplied water outwardly therefrom by centrifugal force;
- an impingement surface, generally concentric to said axis, for breaking up said outwardly propelled water into fine droplets;
- means to intake a stream of air for entraining said fine droplets and thereafter to discharge said stream of air to the surroundings;
- a rotatable shaft coupled to said body;
- drive means for rotating said shaft and said body, said drive means including a motor;
- a fan coupled to said drive means;
- and
- a water supply, including a reservoir;
- said impingement surface having a multiplicity of sawtooth ridges, each defined by a broader, more gradually inclined first side that faces toward the direction of rotation of said rotatable body, and a narrower, steeper second side that faces away from the direction of rotation of said rotatable body;
- and
- said rotatable body having a generally circular rim, and being bell-shaped, with a broader flared rim and a narrower lower portion immersed in said reservoir.
