Odor-removing hinge system for toilets and portable commodes

摘要

An odor-removing hinge system and method of use for withdrawing noxious odors from toilets and portable commodes is disclosed. The present seat hinge system includes an integrated housing that functions as a portion of an exhaust pathway for noxious gases expelled within the toilet bowl. The present hinge system includes at least one hollow bolt disposed in fluid communication with the housing, which is used to secure the toilet seat to the toilet. In one embodiment the noxious gases within the toilet bowl are carried by convection or vacuum via connective tubing to an exhaust conduit installed in an adjacent wall. In other embodiments the noxious gases are directed through a detachable air filter assembly secured to the housing and the odorless filtered air is recirculated. In a method of use the present hinge system is retrofitted to existing toilets and portables commodes in replacement of standard toilet seat hinges.

1. An odor-removing hinge system for toilets and portable commodes, said hinge system comprising:
a toilet seat hinge assembly configured for pivoting a toilet seat and a seat cover from an open position to a closed position, wherein said toilet seat hinge assembly includes an upper pair of hinge plates attached to said seat cover, a base plate attached to said toilet and a plurality of arcuate hinge plate segments for adjustable attachment to an underside of said toilet seat, wherein each of said segments is configured for articulating engagement with a mating adjacent segment to adapt said hinge assembly to toilet seats of different configurations, said hinge assembly further comprising an integral housing that defines an internal conduit having an inlet opening and an exhaust opening formed therein, said inlet opening being disposed in fluid communication with a toilet bowl cavity within a toilet, wherein at least one hollow hinge bolt extends from said integral housing in fluid communication with said internal conduit to conduct air and noxious gases from said hinge assembly to an exhaust conduit; a brushless fan motor disposed in fluid communication with said exhaust opening of said internal conduit enabling said air and noxious gases to be withdrawn from said toilet bowl cavity through said internal conduit and urged to said exhaust conduit; and fan motor actuating means including a power source for automatic operation of said fan motor in said open position of said seat cover, wherein said fan actuating means further includes a magnetically actuated switch disposed within said integral housing for automatic operation of said fan motor each time said seat cover is lifted.
