At this time, normally, the forward voltage force switch 51 disposed in the purified water supply flow path 20 is closed to provide the electrolytic action, but the flow path is also switched to the backwash water supply flow path 25. In this way, the reverse voltage force switch disposed in the backwash water supply passage 25
52 is in a closed state, and the + and-poles are reversed, and a reverse electrolytic action for removing scales and the like attached to the electrodes can be provided.

After that, the backwash acidic water generated by the reverse electrolytic action flows out of the alkaline water tank 24. The backwash acid water is supplied to an alkaline water outlet 34, an alkaline water outlet channel.
40, alkaline water extraction flow path 42, flow path switching valve 43, this time as a branch flow path for backwash acidic water extraction, a branch flow path for alkaline water extraction
45. In this case, the water is discharged to the outside through the backwash alkaline water outlet branch channel 45a that functions as a backwash acid water outlet. On the other hand, backwashed alkaline water generated by the reverse electrolytic action flows out of the acidic water tank 23. The backwashed alkaline water is discharged to the outside through the acidic water outlet 37, the acidic water outflow channel 41, the acidic water outlet channel 46, and the acidic water outlet 46b. The outlets for the backwash acidic water and the backwash alkaline water are provided at positions away from the purified water supply port 18a and the alkaline water outlet 44a to prevent accidental ingestion.

In addition, a means for recognizing insoluble water (for example, a buzzer or the like) may be replaced with a water purifier A or an electrolytic water purifier C.
It is also conceivable to provide the

As described above, the flow path switching valve (flow path switching valves 15 and 18), the separate flow path (backwash water supply flow path 25), and the reverse electrolysis switch (reverse voltage switch 52) are connected to the water purifier A. This is convenient because the reverse electrolytic action for removing the scale and the like attached to the electrodes can be given only by operating the operation handle 50 of the water purifier A at the user's hand position. Here, the forward voltage switch 51 and the reverse voltage switch 52 are disposed inside the electrolysis water conditioner C.

The backwash water from the water purifier A may be discharged to the outside after passing through the electrolytic water conditioner C without performing the electrolytic action in the electrolytic water conditioner C.
