IPC: C02F1/46
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent the saprophytic propagation in an electrolytic bath during the stop of water supply without special operation by a user. SOLUTION: A channel 3d by-passing a pure water tank 9 is installed, and a valve 20 which is opened during the stop of water supply is installed in the channel 3d. In this way, during the stop of water supply, since raw water containing residual chlorine, which does not pass through the tank 9, is introduced into an electrolytic bath 10 through the channel 3d, the saprophytic propagation is prevented in the bath 10. Since the channel 3 is closed by the valve 20 during the introduction of raw water, pure water which has passed through the tank 9 is supplied stably during the passage of water, and no special operation by a user is required for opening/closing the channel 3.
