Abstract: A flush toilet which including a bowl portion having a waste-receiving surface, a rim and a recess; a water spouting portion for spouting the flush water forwardly; and a drainage conduit. The recess of the bowl portion has a bottom below a pooled water level, and a wall surface connecting between the bottom and a lower edge of the waste-receiving surface, wherein the bottom of the recess has a front bottom surface and a rear bottom surface. The bowl portion is configured to allow flush water to form a major stream which is directed to flow from an front end of the bowl portion toward the inlet of the drainage conduit, and the rear bottom surface of the bottom is configured to allow a part of the major stream to collide therewith, and then guide the collided major stream to a front region inside the drainage conduit.

Abstract: A flush toilet which includes: a bowl portion having a waste-receiving surface, a rim and a recess; a first rim spout portion which spouts flush water toward a front end of the bowl portion so as to form a swirl flow; and a second rim spout portion which spouts flush water so as to form a swirl flow having a same flow direction as that of the swirl flow formable by the first rim spout portion. The bowl portion is configured to allow flush water spouted from the first rim spout portion to form a major stream which flows from the front end of the bowl portion into the recess, and allow flush water spouted from the second rim spout portion to flow into the recess from a lateral side of the bowl portion and then merge with the major stream M.
