URINAL

摘要

A urinal capable of suppressing the flow speed differential between the flow speed of flush water flowing into the front side of an ascending pipe and the flow speed of flush water flowing into the back side thereof, and of suppressing the occurrence of stagnation in the flow of flush water, and of suppressing the occurrence of uric scale. The urinal having a discharge trap including a horizontal pipe; a top portion of horizontal pipe is formed by a return flow path-forming portion at the bottom end of the shared wall; and a resistance portion for slowing the flow speed of flush water flowing in the vicinity of this bottom portion is formed at the bottom portion of the horizontal pipe.

主权项

1. A urinal in which a bowl portion is flushed with flush water, having:
a bowl portion furnished with a discharge opening at the bottom; a discharge trap into which flush water which has passed through the discharge opening flows, for accumulating flush water and forming a water seal; and a connecting portion for connecting the discharge trap with discharge plumbing for discharging water connected on the downstream side of this discharge trap; whereby the discharge trap comprises: a descending pipe extending downward from the discharge opening; and an ascending pipe extending upward; whereby the rear wall of the descending pipe and the front wall of the ascending pipe are formed by a shared wall; and the discharge trap further comprises: a horizontal pipe connecting the downstream end of the descending pipe and the upstream end of the ascending pipe, whereby the top portion of this horizontal pipe is formed by a return flow path-forming portion at the bottom end of the shared wall, and a resistance portion for reducing the flow speed of flush water flowing in the vicinity of the bottom portion is formed at the bottom portion of the horizontal pipe.
