Abstract
Abstract The present apparatus for a toilet has the following features: (1) a spray conduit in a recess in the bottom of the toilet seat at the back; (2) a fluid-tight, rotatable water supply fitting aligned with the hinge axis of the toilet seat and connecting the spray conduit in the seat to an external water pipe; (3) a switch-operated valving arrangement for purging the spray conduit in the seat of standing water and filling it with hot water, and then causing the spraying operation to take place; (4) a switch-operated mechanism for flushing the toilet; (5) a pressure switch in the toilet seat to prevent spraying or flushing except when the seat is down and a person is seated on it; and (6) wiring extending through a tubular safety frame for the toilet to switches at the front for the valving arrangement and the toilet flushing mechanism.
