Abstract:
1. A flush toilet in which flush water cleanses the toilet and expels waste, the toilet comprising: a bowl portion having a bowl-shaped waste-receiving surface and a rim portion; a trap pipe connected to and extending from the bottom of the bowl portion to expel waste, and defining the initial accumulated water level of the bowl portion; a shelf portion formed on the waste-receiving surface extending from a back portion of the bowl portion to at least a side portion of the bowl portion and having a portion which extends above the initial accumulated water level; a protruding portion formed on the waste-receiving surface adjacent an upper region of the shelf portion so as to at least partially cover the shelf portion; a first orifice for issuing flush water on a top edge of the waste-receiving surface, forming a swirl flow on the waste-receiving surface; a second orifice for issuing flush water onto the shelf portion, to discharge flush water from a gap between the protruding portion and an inner perimeter portion of the shelf portion, the gap being positioned at the side portion of the bowl portion, such that the flush water discharged from the gap collides with a part of the bowl portion to induce up and down stirring flow of the flush water in the bowl portion and causes an accumulated water level to rise substantially above the initial accumulated water level; a first flow path for supplying flush water to the first orifice; and a second flow path for supplying flush water to the second orifice.
