URINAL SYSTEM AND WASHING METHOD OF URINAL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a urinal system capable of preventing accumulation of foreign substances within a lateral piping while saving water with a simple structure.SOLUTION: A urinal system includes: plural urinals 10-12; and a washing water supply pipe 20 for supplying intermediate water as washing water. The washing water supply pipe 20 for supplying intermediate water and a lateral pipe 40 are directly connected to each other via a by-pass pipe 60. A predetermined amount of intermediate water is flown in the lateral pipe 40 at optional timing to thereby flow out foreign substances such as hair trapped within the lateral pipe 40. The by-pass pipe 60 is interposed by a valve mechanism 61 to supply the intermediate water to the lateral pipe 40 and thus, no tank is required to be disposed in the midway. The urinal system of a simple structure is achieved at a low cost.
