Abstract: A toilet has a trapway extending between a bowl opening and a toilet outlet opening. A heel links and provides a bend between a down leg and an out leg of the trapway. The heel has a cross-sectional profile having a major dimension and a minor dimension. The major dimension increases as the down leg transitions into the heel and reduces as the heel transitions into the out leg. This heel configuration in the trapway forms a siphon during a flushing action of the toilet.

Abstract: A flush toilet bowl comprises a bowl part (1) and a discharge trap (2) formed continuously at the bottom of the bowl part. The discharge trap (2) further comprises a rising channel (22) extending in the obliquely upward direction from the bottom of the bowl part, a first weir (27) formed at the upper end of the rising channel, a descending channel (23) extending downwardly from the first weir, and a cross-laid channel (24) extending substantially in the horizontal direction from the lower end of the descending channel and having a discharge opening (25) at the end. The cross-laid channel (24) is provided with an upwardly bent second weir (28) between the lower end of the descending channel and the discharge opening, and a gathered water part (29) is formed between the second weir (28) and the lower end of the descending channel. The descending channel is formed in the vicinity of the lower end thereof with a horizontal part (26) extending horizontally toward the cross-laid channel (24).

Abstract: In connecting a flushing port (2) of a toilet stool (1) which is formed so as to face the floor surface to which the toilet stool (1) is installed to a drainpipe (3) of the building, the connection is made by means of a flushing-side connecting pipe (6) which connects to the flushing port (2), a drain-side connecting pipe (7) which connects to the drainpipe (3), and a linking pipe (8) which makes connection between the above-noted two pipes. In making the pipe connections, the linking pipe (8) is cut off in accordance with the distance between the flushing port (2) and the drainpipe (3) or pipe insertion overlap can be used to adjust the length of the linking pipe (8).

Abstract: A water closet having a trap drainage exit in a wall above a floor, in which at the time of flushing, a vent space is partitioned in a wall-like manner by water falling from a weir. A rise in the water level of a sump portion of the trap results, and air within the trap is quickly forced toward the drainage exit side by the force of the water flow to cause the interior of the trap drainage to have a decreased pressure so that siphon action easily occurs. When the feed rate of water from a tank slows, to terminate the siphon action, air is promptly introduced into the siphon area from a notch in a partitioning wall, whereby the air introduction is hastened and the siphon effect is terminated quickly.

Abstract: A water closet has a flush tank which reduces the head of flush water presented to a downwardly converging bowl which receives waste to be discharged through an outlet to a siphon trap, the bowl having a rim which causes the flush water to be presented to the trap in a vortex fashion. The trap is U-shaped and includes an upleg and downleg, the upleg having a converging-diverging cross-section to cause the dischrge to be pushed quickly from the bowl into the downleg, which becomes filled and creates a siphon. As waste travels down the downleg it passes through an expansion chamber which imparts a swirling movement to the waste and is again restricted at the outlet, which prevents air from entering the trapway and breaking the siphon.

Abstract: The provision of a flush guiding means at a position with respect to main flush inlet to thereby constitute a very strong and swift correlated flushing action to readily remove the waste out of the bowl with a minimum amount of water and silent flushing operation.
