Flush toilet

A flush toilet that uses a prescribed amount of cleansing water to cleanse the toilet and discharge waste, said flush toilet comprises:

• a bowl having a bowl-shaped waste receiving surface, a rim constituting an upper edge portion whose inner surface overhangs inward and a shelf formed between the rim and the waste receiving surface;
• a drainage channel whose inlet is connected to the bottom of the bowl for discharging waste;
• a first water channel having an end forming a first water spout for spouting a first amount of cleansing water onto the shelf of the bowl to form a vortex, the first water channel supplying the first amount of cleansing water to the first water spout;
• a second water channel having an end forming a second water spout for spouting a second amount of cleansing water onto the shelf of the bowl in the same direction as the swirling direction of the vortex, the second water channel making a substantially horizontal U-turn prior to supplying the second amount of cleansing water to the second water spout, the first amount of cleansing water being greater than the second amount of cleansing water;
• and
• a jet hole section arranged to spout water toward the inlet of the drainage channel;
• wherein the bowl is substantially elliptical, having laterally opposed sides and a fore and an aft end, the sides having a radius of curvature that is relatively large compared to a radius of curvature of the aft end, the first water spout is located on one side of the bowl relative to its fore-aft center axis at a location adjacent a point where a radius of curvature of the bowl changes from a smaller value to a larger value and the second water spout is located on the other side of the fore-aft center axis at a location adjacent a point where the radius of curvature of the bowl changes from a larger value to a smaller value.
