Claim 13

The air treating apparatus defined in claim 1 wherein means are provided for removably securing said tray to said housing comprising a mounting flange on said tray, a mounting flange on said housing engaging said tray mounting flange, and threaded fastening means for securing said flanges together.

Claim 14

A humidifier adapted to be connected to an air system comprising a housing, an evaporator pad mounted in said housing, water distribution means disposed above said evaporator pad for providing a substantially uniformly distributed flow of water to said evaporator pad, said water distribution means comprising an elongated tray having a bottom wall and an upright continuous wall including side and end wall portions, a target element located centrally between said side and end wall portions and extending upwardly from the bottom wall of said tray, said target element having a side wall and being provided on the upper end thereof with a top surface divided into an inner zone and an outer zone, a first pair of internal vertical wall elements extending upwardly from the bottom wall of said tray and located on opposite sides of said target element, each of said first pair of internal wall elements having a pair of end surfaces which abut the side wall of and are secured to said target element and define a channel, a plurality of additional internal wall elements on opposite sides of said target element, each of said additional internal wall elements having a pair of end surfaces which abut the side wall of and are secured on one end surface to said target element and on the other end surface to one of said side wall portions of said tray and define a channel, a plurality of longitudinally spaced apertures formed in the bottom wall of said tray, one aperture being provided for each channel, the top edges of said internal wall elements and the inner zone of said target element being located in generally the same plane, whereby water directed to the apparatus impinges with a certain velocity head on the top surface of said target element from where the water flows and while still in motion impinges upon the top edges of said internal wall elements which divides and directs the flowing water into said channels and from where the water is distributed to the evaporator pad through said apertures.

Claim 15

A humidifier adapted to be connected to an air system comprising a housing, an evaporator pad mounted in said housing, water distribution means disposed above said evaporator pad for providing a substantially uniformly distributed flow of water to said evaporator pad, said water distribution means comprising an elongated tray having a bottom wall and an upright continuous wall including side and end wall portions, a target element located centrally between said side and end wall portions and extending upwardly from the bottom wall of said tray, said target element having a side wall and being provided on the upper end thereof with a top surface divided into an inner zone and an outer zone, a first pair of internal vertical wall elements extending upwardly from the bottom wall of said tray and located on opposite sides of said target element, each of said first pair of internal wall elements having a pair of end surfaces which abut the side wall of and are secured to said target element and define a channel, a plurality of additional internal wall elements on opposite sides of said target element, each of said additional internal wall elements having a pair of end surfaces which abut the side wall of and are secured on one end surface to said target element and on the other end surface to one of said side wall portions of said tray and define a channel, a plurality of longitudinally spaced apertures formed in the bottom wall of said tray, one aperture being provided for each channel, the top edges of said internal wall elements and the inner zone of said target element being located in generally the same plane, whereby water directed to the apparatus impinges with a certain velocity head on the top surface of said target element from where the water flows and while still in motion impinges upon the top edges of said internal wall elements which divides and directs the flowing water into said channels and from where the water is distributed to the evaporator pad through said apertures.
