<P>PROBLEM TO BE SOLVED: To provide a urinal capable of suppressing the occurrence of a urinary calculus in a drain horizontal branch pipe while securing the water-saving performance. <P>SOLUTION: In a urinal, the flow speed decreases at a downstream overflow part TPe and therefore, washing water Wf flows into a drain horizontal branch pipe in a state where the instantaneous flow is relatively low. <P>COPYRIGHT: (C)2012,JPO&INPIT |
