As shown in FIGS. 1 and 2, a main body 3 of the electrolytic water conditioning apparatus 1 includes a diaphragm electrolytic cell in which a negative electrode 7 and a positive electrode 8 are partitioned into a cathode chamber 10 and an anode chamber 11 by an electrolytic diaphragm 9. 2
A water supply pipe 12 such as tap water is connected to a water supply side of the diaphragm electrolyzer 2, and an alkaline water drainage pipe 13 communicating with the cathode chamber 10 and an anode chamber 1 are connected to a drainage side of the electrolyzer 2.
1 is provided with a continuous electrolytic water generator 15 to which an acidic water drain pipe 14 communicating with 1 is connected. Note that a water purifier 16 is usually provided in the water supply pipe 12.

The alkali ion water drain pipe 12 and the acidic water drain pipe 13 are separately connected to a pair of drain pipes (not shown) in the curran 5 mounted on the kitchen table 6,
The drain ports 4a and 4b at the ends of the pair of drain pipes are connected to each other. The drain outlets 4a and 4b may be provided in common for one carran 5 as shown in FIG. 1 or may be provided separately for separate carans 5 and 5 as shown in FIG.

The main body 3 of the electrolytic water conditioning apparatus 1 shown in FIG. 1 further includes a chloride salt such as sodium chloride (NaCl) and hydrochloric acid (HCl) added to water passing through the water supply pipe 12 of the continuous electrolytic water generator 15. A chemical solution adding device 17 for adding
This chemical solution adding device 17 connects a chemical solution supply pipe 19 to a water supply pipe 12 from a chemical solution tank 18 of a chloride salt aqueous solution and hydrochloric acid,
The chemical supply pipe 19 is preferably provided with a motor-operated on-off valve 20 interposed therebetween. When the on-off valve 20 is opened, a fixed amount of the chloride salt aqueous solution and hydrochloric acid are added to the water in the water supply pipe 12. I have. Although not shown, the chemical solution may be sent out by a metering pump.

Further, the main body 3 of the electrolytic water conditioning apparatus 1 shown in FIG.
The mixing pipe 21 branched from the alkaline ionized water drainage pipe 13 is connected to the acidic water drainage pipe 14, and an electrically operated flow path switching valve 22 is provided at the branch portion, whereby the alkaline ionized water drainage is performed. The water in the pipe 13 can be selectively supplied to the alkaline water discharge port 4 a of the curan 5 and the acidic water drain pipe 14.

The chemical liquid adding device 17 and the mixing line 21 are
The water in the anode chamber 11 generated by the electrolysis in the electrolytic cell 2 and the cathode chamber 10
Is mixed to produce sterilized water containing a large amount of hypochlorous acid in the entire feedwater, chloride salts such as sodium chloride adjust the chlorine concentration of the electrolytic mixed water, and hydrochloric acid is the electrolytically generated water. Is adjusted to pH 3 to 8, preferably pH 4 to 7 to adjust a desired hypochlorous acid sterilizing water.

Thus, the apparatus shown in FIG.
7 is closed, and the flow path switching valve 22 of the mixing line 21 is closed.
When the water passed through the electrolytic cell 2 is electrolyzed in a state where the water is opened to the alkaline water discharge port 4a side of the curran 5, alkali ion water and acidic water are separately generated in the electrolytic cell 2, and the alkaline water is alkaline water. Water is taken from the alkaline water outlet 4a of the caran 5 through the drain pipe 13 and the acidic water is drained through the acidic water drain pipe 14.

When the water passed through the electrolytic cell 2 is electrolyzed while being opened to the side, the electrolytic water discharged from the cathode chamber 10 of the electrolytic cell 2 merges with the water discharged from the anode chamber 11 so that the total amount of supplied water is It becomes sterile water containing a large amount of chlorite water and is taken out from the drain port 4b through the acidic water drain pipe 14. In this case, since 80% or more of the free residual chlorine in water exists in the form of hypochlorous acid when the pH is in the range of 3 to 8, in order to efficiently generate hypochlorous acid, the pH of the mixed water must be adjusted to pH of the mixed water. Is adjusted to 3 to 8, preferably 4 to 7. In this way, the apparatus of FIG. 1 can selectively generate alkaline ionized water and hypochlorite sterilized water by electrolysis.

As the flow path switching valve 22 of the mixing line 21 and the opening / closing valve 20 of the chemical liquid adding device 17, both electric valves operated by signals are used, and the operation switches 23 of these electric valves are connected to the body of the callan 5.

That is, the electrolyzed water conditioning apparatus 1 of FIG. 2 also includes the main body 3 and the curran 5 that constitute the continuous electrolyzed water generator 15 similar to FIG. In addition to the above configuration, the apparatus shown in FIG. 2 has a bypass pipe 25 branched from the water supply pipe 12 of the electrolytic cell 2 via a flow path switching valve 24 connected to the acidic water drain pipe 14 of the electrolytic cell 2. A mixing section 26 of sodium hypochlorite (NaClO) is interposed in the bypass pipe 25.

The flow path switching valve 24 of the water supply pipe 12 is used for selectively switching the raw water to be supplied to the electrolytic cell 2 and the bypass pipe 25 to supply water.
The switching operation is performed by a switch 23 installed in the control unit.

Thus, the apparatus shown in FIG.
Is opened to the electrolysis tank 2 side, and electrolysis is performed while supplying raw water to the electrolysis tank 2, thereby producing alkali ionized water and acidic water in the same manner as in the apparatus of FIG. 4a, and the acidic water is drained from the acidic water drain pipe 4b. On the other hand, when the flow path switching valve 24 is opened to the bypass pipe 25 side, the raw water passes through the bypass pipe 25 and dilutes the sodium hypochlorite added in the mixing section 26 to have a desired concentration of hypochlorous acid. It is adjusted to a sodium aqueous solution and drained through an acidic water drain pipe 14. Of course, in this case, the application of the electrolytic voltage to the electrolytic cell 2 is stopped. In this way, alkaline ionized water and an aqueous solution of sodium hypochlorite are selectively produced.
