INLET SHROUDS FOR FANS USED PRINCIPALLY IN WATER-CIRCULATION PUMPS OF SWIMMING POOLS AND SPAS

摘要

Motor housings and shrouds are detailed. Inlets of the shrouds may be included on any or all portions of their peripheries (as well as on rears of shrouds if desired). Air hence need not necessarily be drawn wholly linearly into the shrouds, permitting the shrouds to abut, or at least be closely proximate, other objects without materially diminishing air flow into the shrouds. Moreover, plates within the shrouds may be positioned so as to create torturous paths through which the air must travel. Channeling air through these torturous paths helps reduce noise as the air moves to the fans.
