BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion water supply apparatus, and more particularly to an ion water supply apparatus capable of cleaning electrodes or alternately using the electrode tanks by applying a reverse voltage to electrodes arranged in an electrolytic cell. Regarding the improvement of the device.

2. Description of the Related Art A running water type ion water supply device which is connected to an outlet of a tap water and electrolyzes while running tap water to generate alkaline ionized water and acidic ionized water has been generally known. Examples of such a conventional ion water supply device include (1) "ion water supply device" according to Japanese Utility Model Application No. 62-129390 (Japanese Utility Model Application No. 64-36092) and (2) Japanese application No. 63- No. 74059 (Practical application 1-179
No. 798) related to "field ionized water generator".
In the conventional ionized water supply device of the above (1), the water supply line connected to the outflow side of each electrolytic cell portion of the electrolytic cell is connected to a single supply pipe via a single three-way valve. Therefore, if one of the alkaline ionized water and the acidic ionized water produced at the same time is caused to flow through the supply pipe, the other cannot flow. Further, the conventional ion water supply device of the above (2) prevents the ion water of the opposite polarity from being mixed in the ion water supply device of the type in which the electrolytic cell is cleaned by applying a reverse voltage to the electrodes in the electrolysis cell. However, there is a problem that the structure becomes complicated.

By the way, when a reverse voltage is applied to the electrode plate of the electrolytic cell to wash the electrode plate, during the cleaning, ionized water of the reverse nature is generated in each electrolytic cell portion of the electrolytic cell, which is different from the normal use. Therefore, this reverse ionic water must be discarded. In order to eliminate such waste, as shown in FIG. 7, a three-way valve f and a pair of water supply lines d and e connected to the outflow sides of the two electrolytic cell portions b and c of the electrolytic cell a are respectively provided. It is necessary to connect g and switch both three-way valves at the same time to control the connection between the pair of supply pipes h and i and the electrolytic cell portion of the electrolytic cell. However, in such a device, it is necessary to provide two three-way valves, so that there is a problem that a large space is required and a sequence for operation is complicated.

Further, if a valve having an airtight structure is used as the three-way valve, the ion water supply device does not normally have a pressure resistant structure, and therefore the effluent side of the electrolytic cell is closed by an erroneous operation to pressurize the inside of the electrolytic cell. There is also a problem that the electrolytic cell will be damaged.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a structure in which a pair of water supply lines connected to the outflow side of an electrolytic cell are provided with a single four-way valve in an ion water supply device. Achieving compactness and simplification.

[0006]

One of the inventions of the present application is that the inside is divided into two electrolytic cell parts by a diaphragm, and an electrode is arranged in each part so that alkaline ionized water and acid In an ion water supply device provided with an electrolyzer for generating ion water and a pair of water supply lines connected to the outflow side of each part of the electrolyzer, each port of the four-way valve is provided in the water supply line of the pair. And the remaining ports are respectively connected to an outlet for alkaline ionized water and an outlet for acidic ionized water. Another invention of the present application is an electrolytic cell in which the inside is divided into two electrolytic cell portions by a diaphragm and electrodes are arranged in the respective portions to generate alkaline ionized water and acidic ionized water from inflowing water. , In a pair of water supply lines connected to the inflow side of each part of the electrolytic cell, and a pair of water supply lines connected to the outflow side of each part of the electrolytic cell, Connect each port of the first four-way valve to the water supply line, connect the remaining ports to the outlet for alkaline ionized water and the outlet for acid ionized water, respectively, and connect the pair of water supply lines to the second four-way valve. It is configured to be connected to each water supply source via.

[0007]

In the above structure, when water is supplied into each electrolytic cell part of the electrolytic cell while the pair of electrodes in the electrolytic cell are charged to opposite polarities, alkaline ionized water is contained in one electrolytic cell part. Is generated and acidic ionized water is generated in the other electrolytic cell portion. The generated alkaline ionized water and acidic ionized water flow to the four-way valve through the respective water supply lines, and flow out from the respective outlets via the four-way valve.
When the electrodes in the electrolytic cell are charged oppositely to wash the electrodes, acidic ionized water is generated in the one electrolytic cell portion and alkaline ionized water is generated in the other electrolytic cell portion.
Therefore, if the four-way valve is switched and the connection between the water supply line and each outlet is changed, the alkaline ionized water and acidic ionized water generated during electrode cleaning will flow out from the corresponding outlets as before. Can be done.

Another embodiment of the present invention is shown in FIG. In this embodiment, the structure on the downstream side of the electrolytic cell 2 is the same as that of the above embodiment, but the upstream side is different. That is, in the ion supply system 1'of this embodiment, the water supply lines 3a 'and 3b' are the ports 13a 'of the four-way valve 10'.

On the other hand, the acidic ionized water then enters the port 13b of the four-way valve 10 through the water supply line 6b, exits the four-way valve from the port 13d and flows to the alkaline ionized water outlet 7b.

When the voltage applied to the two electrodes 24 and 25 of the electrolytic cell 2 is reversed from that in the normal operation described above to wash the electrodes, that is, when the electrode 24 itself is positively charged and the electrode 25 itself is negatively charged. As described in the previous example, acidic ionized water is generated in the electrolytic cell portion 22 and alkaline ionized water is generated in the electrolytic cell portion 23.
