Abstract
A humidifier comprises a container having an air inlet and an air outlet; a water reservoir in the container; an absorbent mass having extensive upper surface and lower surfaces, the absorbent mass being floatable on the surface of water in the reservoir; a plate disposed on the lower surface of the absorbent mass to limit the degree of immersion of the absorbent mass while it floats in the reservoir; and a blower for drawing air through the air inlet and directing it onto the upper surface of the absorbent mass so that the air can deposit particles thereon, and absorb moisture therefrom, prior to flowing out of the container through the air outlet. The humidifier is highly efficient, quiet in operation and not affected by varying water levels.
Claims6
A humidifier comprising:
- a) a container having air inlet means and air outlet means, and defining a water reservoir therein;
- b) a humidifier element floatable on the surface of water in said reservoir having extensive upper and lower surfaces;
- c) blower means for drawing air through said air inlet means and directing a stream of air onto said upper surface of said humidifier element such that it strikes said upper surface and is deflected thereoff toward said air outlet means;
- and
- d) said humidifier element comprising:
- (i) a generally solid block of low density spongy foam material having a main body portion and an undulating upper surface forming said extensive upper surface of said humidifier element;
- and
- (ii) a submerged floating plate supporting said block of low density foam such that when said humidifier element floats in said reservoir said block of low density foam remains partially submerged with said undulating upper surface thereof substantially fully exposed to said stream of air directed thereon whereby entrained particles in said stream of air are deposited on, and moisture is absorbed from, said undulating upper surface of said block as said stream of air is deflected thereoff.
