Abstract
Abstract A humidifier assembly comprises a two part housing with a lower housing member being a water reservoir pan attached along opposite ends by projecting lips and slidable clamp strips to an inverted U-shaped upper housing member that may be reversed side for side for different air flow direction connections. The upper housing member supports all of the moving parts including the motor, rotor and float valve. The float valve unit includes an integral inlet conduit, discharge nozzle and shroud pivotally mounting a valve seat controlled by the float.

Claim 3
Dependent Claim
252 words
A humidifier assembly comprising an upper housing part having a top wall from opposite ends of which depend substantially parallel end walls, opposite front and rear side walls depending from said top wall and formed with downwardly facing openings of substantially the same shape and size for selective registry with a plenum opening in a hot air heating or like system, a lower housing part providing an upwardly open water reservoir extending across and closing the bottom of said upper part, fastener means releasably securing said housing parts together, means in said upper housing part for supporting and driving a water pick-up rotor that extends between the end walls of said upper housing part and has its lower sector disposed in the water in said reservoir, said rotor being removably separable from its drive and support, means defining an opening in one end wall of the upper housing part opposite an end of said rotor and above said securing means and adapted to be connected to a bypass air flow conduit of said system, either of said side openings of the upper housing part being adapted for positioning adjacent and in registry with said plenum opening in end for end reversed positions of said upper housing part relative to the lower housing part and a removable cover for closing the opposite side wall opening, and both of said side wall openings being of sufficient size to permit bodily removal of the rotor therethrough upon removal of said cover for servicing and/or replacement.
Claim 4
Dependent Claim
252 words
A humidifier assembly comprising an upper housing part having a top wall from opposite ends of which depend substantially parallel end walls, opposite front and rear side walls depending from said top wall and formed with downwardly facing openings of substantially the same shape and size for selective registry with a plenum opening in a hot air heating or like system, a lower housing part providing an upwardly open water reservoir extending across and closing the bottom of said upper part, fastener means releasably securing said housing parts together, means in said upper housing part for supporting and driving a water pick-up rotor that extends between the end walls of said upper housing part and has its lower sector disposed in the water in said reservoir, said rotor being removably separable from its drive and support, means defining an opening in one end wall of the upper housing part opposite an end of said rotor and above said securing means and adapted to be connected to a bypass air flow conduit of said system, either of said side openings of the upper housing part being adapted for positioning adjacent and in registry with said plenum opening in end for end reversed positions of said upper housing part relative to the lower housing part and a removable cover for closing the opposite side wall opening, and both of said side wall openings being of sufficient size to permit bodily removal of the rotor therethrough upon removal of said cover for servicing and/or replacement.
