PROBLEM TO BE SOLVED: To prevent the corrosion and deterioration of water paths and to make work management simpler and more efficiency by switchably and selectively connecting respective supply sections for sterilizing water and washing water to respective water circuits of instruments and sinks of plural chair units, and discharging the washing water and sterilizing water after use from discharge pipelines. SOLUTION: When a simultaneous manipulation switch for a console panel 46 is pushed, washing water opening/closing valves 19a and sterilizing water opening/closing valves 19b on a discrete side close and washing water opening/ closing valves 20a and sterilizing water opening/closing valves 20b on a simultaneous side open. When, the simultaneous sterilizing switch is, thereupon, pushed, the washing water opening/closing valves 21 on the simultaneous side close and the sterilizing water opening/closing valves 21b open. The sterilizing water is then supplied to sinks 41 and respective chair unit sections 42 to 45. The sterilizing water passes the water circuits of sinks 6 and the water circuits of the instruments of respective chair units 2 to 5 and is then discharged outside from discharge pipelines 13 through discharge flow passages 14. As a result, the inside of the water circuits may be easily and efficiently sterilized. |
