PURPOSE: To ensure the siphon effect and increase the washing effect and the water-saving effect, by mixing air into the jet-flushing water to wash the toilet stool or directly washing it without air bubbles by a controller.
CONSTITUTION: When the feed water pressure of washing water flowing in the feed water pipe 7 of a toilet stool 1 is high, the air adjusting valve 11 is opened large to increase the air volume flowing in the air pipe 8. In this case, the air mixed in the jet-flushing water ejected from the jet nozzle 6 is increased. When the feed water pressure is reversely low, the opening of the air adjusting valve 11 is made small to lesson the mixed air. In this case, the air adjusting valve is opened large to mix air into the flushing water at the initial stage of the jet-flushing by a controller 13 to break night soil in the sewage W. Thereafter, the sewage W with night soil is drained by the siphon action of flushing water without air bubbles. Moreover, in another control of the controller 13, the air adjusting valve 11 is closed at the initial stage of the jet-flushing and the sewage W is flushed out to the trap 4 side to ensure the siphon action.
