摘要： A water closet having a drainage port in a position higher than the floor. During a flushing operation, an air vent space is partitioned by a water wall formed by a water flux dropping from a dam and by an increase of the water level in a reservoir, and the air in a trap is pushed out speedily toward the drainage port due to the rapid flow of water to make vacuous the interior of a trap's drainage passage and make it ready to start a siphoning action. When the feeding of water from a tank has been completed, so that the continuous siphoning action approaches the end thereof, a notch is formed in the water wall to permit the air to enter the air vent space immediately. Accordingly, the entry of the air into the air vent space occurs earlier, and the siphoning action terminates speedily.
Abstract
A water closet having a drain hole above a floor, in which at the time of flushing, a vent space is partitioned in a wall-like manner by a water bundle falling from a weir portion and a rise in water level of a sump portion, air within a trap is quickly forced toward a drain hole side by water power to render the interior of a trap drainage negative pressure so that siphon action easily occurs, and when feed of water from a tank terminates to be about to terminate siphon duration, air is promptly introduced from a notch in a partitioning wall whereby timing of air introduction is quickened and siphon is quickly shut off.
摘要翻译：水箱的排水口位于高于地面的位置。在冲洗操作期间，排气空间由通过从大坝下落的水流通道形成的水壁以及储存器中的水位的增加而分隔开。陷阱中的空气由于水的快速流动而迅速向排水口推出，使得陷阱排水通道的内部变空，并使其准备好开始虹吸作用。当从罐中供水已经完成时，连续的虹吸作用接近尾端，在水壁上形成一个凹口。这个缺口允许空气立即进入通风口。

摘要： Problem: To provide a flush toilet capable of effectively expelling waste using a swirl flow without utilizing a strong siphon action.
Solution Means: The present invention is a flush toilet (1), comprising a bowl portion (2) having a bowl-shaped waste-receiving surface and a rim portion, the inside wall surface on the top edge of which protrudes inward; a trap pipe (4) connected to the bottom portion of the bowl portion to expel waste within the bowl portion; a first shelf portion (6) formed to follow the rim portion; a second shelf portion (8) formed on the waste-receiving surface below the first shelf portion and above an initial accumulated water level; a first orifice (10) for issuing water onto the first shelf portion and forming a swirl flow on the waste-receiving surface; a second orifice (12) for issuing water onto the second shelf portion and forming a flow to stir flush water within the bowl portion; and first and second flow paths (14, 16) for respectively supplying flush water to the first and second orifices.

摘要： A water closet comprises a bowl part (2) in the form of a bowl in which flush water is stored; a rim water path (1) provided in the peripheral edge portion at the upper end of the bowl part; a substantially inverted U-type trap discharge passage (3) which is formed in communication with the bottom of the bowl part and which is provided with a weir (37) on the way; and a water supply part (5, 6) provided at the back of the bowl part and supplying flush water to the bowl part and the rim water path, said trap discharge passage (3) being formed with a flush water peeling-off part (4) constituted by suddenly changing the form of the inner wall surface from the weir (37) to the descending passage (33) of the trap discharge passage. Further, a flow resistance means (63) for delaying an arrival of flush water at the rim water path (1) is provided between the water supply part (5, 6) and the rim water path (1).
