초록 ▼

An exhaust fan for bathrooms and the like having two principal structural elements--a housing assembly and a motor plate assembly--wherein the housing assembly includes a generally cylindrical housing formed of injection molded plastic. The housing assembly includes a circumferential mounting flange and mounting clips carried thereon for mounting the fan in a ceiling panel or the like in an arbitrary angular orientation. Flexible mounting tabs on the motor plate assembly releasably engage notches on the housing for snap together assembly. Integral strain relief for power supply wiring is molded into a wiring compartment in the housing. An oval duct connector having an outer circumferential lip extends from an exhaust outlet and is adapted to releasably engage a round flexibly resilient spring reinforced duct thereover. The motor plate assembly also covers the wiring compartment when fitted into the housing assembly.

[ What is claimed is:] [1.] An exhaust fan for mounting in a circular opening in a panel and providing for unlimited angular positioning of an exhaust port with respect to the ceiling panel, comprising a fan housing having a generally cylindrical body portion adapted to be received within said circular opening,said body portion having the exhaust port extending generally outwardly therefrom and positioned above said panel when said body portion is inserted within said panel opening,said body portion further provided with a generally radially extending circumferential flange proportioned to abut a lower surface of said ceiling panel when said body portion is fully inserted in said circular opening,said housing being rotatable in relation to said panel to position said exhaust port for ease of access to an air exhaust duct above said panel, a plurality of fasteners carried on said flange accessible from a position below said panel,each said fastener having a threaded portion above said flange terminating in a generally radially extending retainer portion, each said fastener being moveable between a retracted position in which said retainer portion is turned to a position adjacent said body portion and an extended position in which said retainer portion extends generally radially from said housing, stop means on said housing defining said retracted and extended positions,each said threaded portion receiving an operator screw extending through a hole in said flange with the driving head of said screw positioned below said flange for access from a position below said panel,said fastener being rotatable by said screw from said retracted position to said extended position by said stop means and thereafter moveable linearly along said screw to draw said retainer portion against said panel for securing said housing in a selected position with respect to said panel, andwherein said exhaust port is oval in cross-section over a substantial portion of its length, and is proportioned to receive a spring reinforced flexible exhaust hose thereover by the flattening of said hose into an oval shape against its reinforcing spring whereby the resiliency of said hose when released tends to cause said hose to return to a circular shape on said exhaust port causing the sides of said hose to grip said exhaust port along its long transverse axis.
