Abstract
Abstract A humidifier for mounting in the plenum of a forced air heater and/or conditioner comprising an elongated U-shaped pan horizontally mounted in the plenum with an upwardly and slightly inwardly inclined U-shaped filter member supported therein. A spray nozzle for generating a wide-angle, flat spray is supported in the plenum opposite the filter member to direct a liquid spray across the plenum and onto the filter member transverse to air flowing upwardly in the plenum. The spray is designed to have a velocity and density relative to the upwardly flowing air sufficient to redirect the air into and through the filter member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A humidifier for mounting in the plenum of a forced air heater and/or conditioner comprising: an elongated pan having an open top; means for horizontally mounting said pan in said plenum; an open top filter member extending vertically from said open top of said pan; nozzle means for producing a high velocity wide-angle, liquid spray; means including pressure regulating means for supplying liquid to said nozzle means to produce a nonvarying liquid spray; and means for mounting said nozzle means in said plenum adjacent an inner wall thereof facing said filter member to direct said high-velocity liquid spray only across said plenum and onto said filter member transverse to air flowing upwardly in said plenum, said spray having a velocity and density relative to said upwardly flowing air sufficient to redirect portions of said air into, through, and upwardly along said filter member.
Claim 2
Dependent Claim
143 words
A humidifier for mounting in the plenum of a forced air heater and/or conditioner comprising: an elongated pan having an open top; means for horizontally mounting said pan in said plenum; an open top filter member extending vertically from said open top of said pan; nozzle means for producing a high velocity wide-angle, liquid spray; means including pressure regulating means for supplying liquid to said nozzle means to produce a nonvarying liquid spray; and means for mounting said nozzle means in said plenum adjacent an inner wall thereof facing said filter member to direct said high-velocity liquid spray only across said plenum and onto said filter member transverse to air flowing upwardly in said plenum, said spray having a velocity and density relative to said upwardly flowing air sufficient to redirect portions of said air into, through, and upwardly along said filter member.
Claim 3
Dependent Claim
88 words
The humidifier of claim 1 wherein said means for mounting said pan and means for mounting said nozzle means are manually adjustable and provide independent adjustment of the horizontal position of said pan and vertical adjustment of the angle of said liquid spray respectively and wherein said pressure regulating means is hand adjustable, whereby said pan, filter member, nozzle, and pressure regulator may be adjusted relative to the velocity of said upwardly flowing air to insure that a resultant vector of said air is through said filter memBer.
Claim 4
Dependent Claim
95 words
The humidifier of claim 1 wherein: said pan and said filter member are generally U-shaped in plan; said nozzle means includes a head having a wide mouth port for producing a wide-angle, flat liquid spray; and said means for mounting said nozzle means supports said nozzle means at an upward acute angle to the horizontal such that said flat liquid spray acts as an upwardly inclined substantially air impervious top of a cavity defined by said spray and an inner surface of said filter member for redirecting said upwardly flowing air through said filter member.
Claim 5
Dependent Claim
46 words
A humidifier of claim 2 wherein said pan includes inner and outer sidewalls joined along a lower edge and extending upwardly therefrom, said sidewalls being substantially concavo-convex in cross section to direct air engaging said pan upwardly along inner and outer surfaces of said filter member.
Claim 6
Dependent Claim
32 words
The humidifier of claim 3 wherein said filter member inclines upwardly and slightly inwardly from a base thereof in said open top of said pan to define a hollow substantially semifrustoconical member.
