Abstract: A mixing chamber for use in a toilet sanitizing system consists of a cylindrical housing having an upper opening closed by a closure cap. The closure cap is removed to gain access to the internal chamber of the housing and is threaded over the upper opening to close the internal chamber. The internal chamber of the housing includes a spring to support a lower surface of a dispenser enclosing a block of germicide substance that is inserted into the internal chamber through the upper opening while the closure cap is removed. The internal chamber has three ports, an upper inlet port that enters the internal chamber tangentially, a middle outlet port exiting the chamber radially, and a lower outlet port radially exiting the chamber and located just above a lower wall of the chamber. The upper port is connected to a source of water, the middle port is connected to a toilet bowl, and the lower port is connected to the associated toilet seat.

Abstract: A self-sanitizing toilet seat cleaning apparatus includes a seat in the shape of a generally circular ring that is rotatably mounted above the toilet bowl and includes a gear on its underside meshing with a pinion gear attached to the drive shaft of a drive motor for the seat. An arm extends over a rear portion of the seat and includes flow passages that convey a disinfectant on top of the seat, under the seat, and into the toilet bowl. Under the arm, a wiper is provided that wipes the top surface of the seat as it rotates. The toilet includes a weight sensor that stops rotation of the seat if a person is sitting on it and a proximity sensor to activate flushing of the toilet and rotation and disinfecting of the seat and bowl.
