Patent ID: 7895682

Claim:
A system intended to remove noxious odors resulting from disposal of human waste into the porcelain bowl of an ordinary flush toilet while seated upon its hinged seat spaced apart from and in contact with the top surface of said porcelain bowl and mounted to the rear of said top surface with a pair of mounting bolts; said system comprising: at least one manifold, at least one hood, conduit, and at least one blower; each said manifold possessing a manifold inlet, a manifold plenum, and a manifold extension with a manifold outlet; said manifold inlet possessing dimensions sufficiently diminutive to fit the same in the space: between the hinged seat and the top surface of the porcelain bowl of an ordinary flush toilet and between the pair of mounting bolts mounting said hinged seat to the rear of the top surface of said porcelain bowl; said manifold plenum possessing communication with said manifold inlet and said manifold extension facilitating air flow through said manifold inlet and then through said manifold plenum and thence through said manifold extension with a negative pressure differential with respect to ambient pressure supplied to said manifold extension; said manifold extension being adapted for connection of said conduit to said manifold outlet; each said blower being remotely located from said manifold and connected with said conduit such that operation of said blower effects the supply of a negative pressure differential upon said manifold inlet with said conduit connected to said manifold extension; each said manifold further possessing two lateral wings each possessing one slot spaced apart from each other and possessing dimensions enabling the mounting bolts of an ordinary flush toilet to be passed therethrough in location of said manifold; each said hood possessing a medial section and two lateral wings each possessing one slot spaced apart from each other and possessing dimensions enabling the mounting bolts of an ordinary flush toilet to be passed therethrough in location of said hood; said medial section of said hood possessing a curved fore edge and a straight rear edge spaced apart from each other a distance sufficient to locate said curved fore edge in an overhang of the rear of the cavity of the porcelain bowl of an ordinary flush toilet and said straight rear edge in contact with said manifold inlet when both said manifold inlet and said hood are disposed upon the rear of the top surface of the porcelain bowl with the mounting bolts for the hinged seat passing through said slots through said wings of said hood and said wings of said manifold; whereby operation of at least one said blower with said conduit connected to at least one said manifold extension effects a negative pressure differential upon said manifold inlet and air borne odors associated with disposal of human waste into the porcelain bowl of a flush toilet are removed with the flow of air under said medial section of said hood into said manifold inlet, through said manifold plenum, manifold extension, and conduit.
