Abstract
In a water closet flushing apparatus of the type in which the flushing water from a flushing water supply source is fed through different flushing water feed lines to a bowl portion and a trap discharge passage defined adjacent to the bottom portion of the bowl portion, a water jet injector is provided so as to inject the flushing water jet toward the trap discharge passage, an opening-closing valve is disposed in each of different feed lines, and the operation of the opening-closing valve is controlled by a control unit. The flushing water is flushed into the bowl portion so as to clean the same while the jet of flushing water is injected into the trap discharge passage to cause the same to act as a siphon, whereby waste matter is discharged.
