PURPOSE: To increase the washing and draining effect and water-saving effect, by mixing air into the washing water fed in the toilet stool and cleaning the bowl face and the wall face of the top part by a jet-flushing water with air bubbles.
CONSTITUTION: A user pushes on a flush valve to supply the flushing water from the water feed pipe 7 to the jet nozzle 6 and mix the air from the air pipe 8 to generate a foamed water. Next, the foamed water is ejected from the ejecting outlet into sewage W in the bowl 2 to flush out the sewage W into the trap 4 to fill it with water and discharge it into the drain pipe by siphon action. In this time, stains stuck on the bowl 2 face and the path wall of the trap 4 are removed by the mixed air in the foamed water and hence, the cleaning effect is increased.
