With the water conditioner C connected, a water purification operation position and a backwash operation position can be set.

Next, a method of using the water purifier A having the above configuration will be specifically described with reference to FIGS.

First, as shown in FIG. 2, a case where the water purifier A is used alone will be described.

In the case of the water purification operation, the raw water flow path switching valve B and the flow path switching valves 15, 18, and 43 are positioned in the state shown in FIG.

Thereafter, the tap water flowing into the raw water inlet 1 from a tap or the like is purified through the safety valve 16, the flow switching valve 15, the activated carbon 12, and the hollow fiber membrane 14. It can be taken out through the valve 18 and the purified water supply port 18a.

In the case of the backwashing operation of the water purifier A, the operation handle 50 is rotated by a predetermined circumferential angle in the state shown in FIG. At the same time, the flow is switched through the flow path 19 and the flow path switching valve 43 is switched so that the alkaline water extraction flow path 42 is connected to the backwash alkaline water extraction branch flow path 45.

Thereafter, the tap water flowing from the tap into the raw water inlet 1 flows through the safety valve 16, the flow path switching valve 15, the flow path switching valve 18, the hollow fiber membrane 14, the activated carbon 12 and the hollow fiber membrane 14 and the activated carbon The backwash water after washing can be discharged to the outside through the flow path switching valve 15.

As described above, when the water purifier A is used alone, as shown in FIG. 2, the flow path connection port 42a, the alkaline water A cap 90 is attached to each of the outlet 44a, the backwash alkaline water outlet 45a, the flow path connecting port 46a, and the acidic water outlet 46b.

Next, referring to FIG. 5, a case where the water purifier A is used with the electrolytic water purifier C connected thereto will be described.

First, a flow path connecting port 42a, an alkaline water outlet 44a, a backwashing alkaline water outlet 45a, a flow path connecting port 46a, and an acidic water outlet 46b, which form a connection portion with the electrolytic water purifier C, are provided. Remove the cap 90 from.

On the other hand, the raw water flow path switching valve B and the flow path switching valves 15, 18, and 43 are positioned as shown in FIG.

Thereafter, the tap water flowing from the tap into the raw water inlet 1 is purified through the safety valve 16, the flow switching valve 15, the activated carbon 12, and the hollow fiber membrane 14. The purified water flows into the acidic water tank 23 and the alkaline water tank 24 of the electrolysis water purifier C through the flow path switching valve 18, the purified water supply port 18a, and the purified water supply flow path 20, and is subjected to an electrolytic action. .

The alkaline water generated by the electrolytic action is supplied to an alkaline water outlet 34, an alkaline water outlet channel 40, an alkaline water outlet channel 42, a channel switching valve 43, an alkaline water outlet branch channel 44, an alkaline water outlet. It can be obtained as alkaline drinking water through 44a.

As described above, the acidic water can be discharged from the casing 10 located at the position at hand of the user, so that the convenience in using the acidic water as the face washing or sterilizing water is improved. Further, since the acidic water outlet 46b is provided at a position below the raw water direct outlet 4 by the distance H, it is easy to recognize the raw water and the acidic water.

In the case of the backwashing operation of the water purifier A, the operation handle 50 is rotated by a predetermined circumferential angle in the state shown in FIG. In addition to communicating with the passage 19, the passage switching valve 43 is switched so that the alkaline water extraction passage 42 is connected to the backwash alkaline water extraction branch passage 45.

Thereafter, the tap water flowing from the tap into the raw water inlet 1 is washed with the safety valve 16, the flow switching valves 15 and 18, the hollow fiber membrane 14 and the activated carbon 12 to clean the hollow fiber membrane 14 and the activated carbon 12. Then, the backwash water after washing is passed through the flow path switching valve 15, the backwash water supply flow path 25, the purified water branch flow path 26, the purified water branch flow path 27, and into the acidic water tank 23 of the electrolytic water purifier C. It flows into the alkaline water tank 24.

At this time, normally, the forward voltage force switch 51 disposed in the purified water supply flow path 20 is closed to perform the electrolytic action, but the flow path is also switched to the backwash water supply flow path 25. As a result, the reverse voltage force switch 52 disposed in the backwash water supply flow path 25 is closed, and the positive and negative electrodes are reversed to provide a reverse electrolytic action for removing scales and the like attached to the electrodes. I can do it.

After that, the backwash acidic water generated by the reverse electrolytic action flows out of the alkaline water tank 24. The backwashed acidic water is supplied to an alkaline water outlet 34, an alkaline water outlet flow passage 40, an alkaline water outlet flow passage 42, a flow path switching valve 43, and in this case, a backflow acidic water outlet branch flow passage. The water is discharged to the outside through a channel 45, this time a branch channel 45a for backwashing alkaline water removal which serves as a backwashing acidic water outlet. On the other hand, from the acidic water tank 23, the backwashed alkaline water generated by the reverse electrolytic action flows out. The backwashed alkaline water is discharged to the outside through the acidic water outlet 37, the acidic water outlet 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, it is conceivable to provide a means for recognizing water that cannot be drunk (for example, a buzzer or the like) in the water purifier A or the electrolytic water purifier C.

As described above, the flow path switching valves (flow path switching valves 15 and 18), the separate flow path (backwash water supply flow path 25), the reverse electrolysis switch (reverse voltage switch 52) are provided to the water purifier A. By providing the water purifier A, a reverse electrolytic action for removing scales and the like attached to the electrodes can be provided only by operating the operation handle 50 (reverse voltage operation switch) of the water purifier A at a position at hand of the user. is there. Here, the forward voltage switch 51 and the reverse voltage switch 52 are disposed inside the electrolysis water conditioner C. In this embodiment, the reverse voltage operation switch is a rotary type, but a push type switch can be applied as a matter of course.

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