Field of the Invention The present invention relates to an ionic water generator for electrolyzing tap water or the like to generate alkaline ionized water and acidic ionic water, and more particularly to an ionic water generator capable of obtaining a stable oxidation-reduction potential value. It is about.

[0002]

2. Description of the Related Art Various ion water generators have been developed as devices for removing impurities in tap water and obtaining water quality suitable for drinking purposes. Such an ion water generator passes tap water through an electrolytic bath and applies a constant voltage in the electrolytic bath to electrolyze water to obtain alkaline ionized water and acidic ionized water. Only
However, the voltage applied to the electrolytic cell is constant, and the pH of the ionic water obtained due to differences in water quality, flow rate and the like is not constant. For this reason, an electrolytic cell unit equipped with a pH detecting device for ionic water and a feedback mechanism has been disclosed in Japanese Unexamined Utility Model Publication No.

It is thought that it may be. However, conventionally, evaluation of electrolytic ionic water was performed only based on pH, and thus evaluation of electrolytic ionic water was not sufficient.

That is, the water quality of the electrolytic ionic water must be evaluated not only at the pH value but also at the oxidation-reduction potential. For this reason, conventionally, water having a constant oxidation-reduction potential even at the same pH is obtained. I couldn't do that.

In the figure, reference numeral 16 denotes a water supply path connecting a water tap 17 and a water supply port 18 of the electrolytic cell 1.
6 is provided with a water purification cartridge 19 for removing impurities contained in water. Reference numeral 4 denotes an electrolytic ion water discharge channel, and two electrolytic ion water discharge channels 4 are provided, and one electrolytic ion water discharge channel 4a is
3 is connected to a discharge port 20 provided in the counter electrode chamber 14, and the other electrolytic ion water discharge channel 4 b is connected to a discharge port 21 provided in the counter electrode chamber 14. On one electrolytic ion water discharge channel 4a, there is provided a multistage dissolution tank 5 in which dissolution chambers 5a are provided in multiple stages.
In the figure, reference numerals 22 and 23 denote solenoid valves, and reference numeral 24 denotes a flow control valve.

In the ion water generator configured as described above, when tap water or the like flows through the water supply port 18 of the electrolytic cell 1 after impurities in the water are removed through the water purification cartridge 19, a voltage is applied between the electrodes 2 and 3. Is applied, electrolysis is performed, and ionic water having a changed pH is generated. That is, when a negative electrode is applied to the electrode 2 serving as a working electrode and a positive electrode is applied to the electrode 3 serving as a counter electrode, alkali ion water is generated in the working electrode chamber 13 and acidic ion water is generated in the counter electrode chamber 14. Will be.

When the solenoid valves 22 and 23 are opened, the alkali ion water generated in the working electrode chamber 13 flows from the discharge port 20 provided in the working electrode chamber 13 to one of the electrolytic ion water discharge passages 4a, and the counter electrode chamber is opened.

4 flows into the other electrolytic ionized water discharge flow path 4b from the discharge port 21 provided. Here, a large amount of reducing substances such as hydrogen gas are generated in the alkaline ionized water by electrolysis. However, the generation of the hydrogen gas or the like in the water is performed in a multi-stage dissolution tank 5 provided in the electrolytic ionized water discharge flow path 4a. The gas is efficiently dissolved, and alkali ion water having a high reducing property, that is, a low oxidation-reduction potential is obtained. Here, in the multi-stage dissolving tank 5, the dissolving chamber 5a can be provided in multiple stages to prolong the contact time between the generated gas and water and promote the dissolution in water. The alkaline ionized water thus obtained is p
Although H becomes 9 to 10 and has a reducing property, it can have a stable reducing property because it dissolves hydrogen gas and the like generated by electrolysis.

Schematic configuration diagram of another gas dissolution mechanism for dissolving gas
Is shown. In Fig. 2, the basic structure is the same as FIG. 1 for a description of parts of the same configuration is omitted. The In Fig 2 is characterized in dissolving vessel 5 in order to increase the solubility in water of the product gas in that a cooling device 6 is provided. The shape of the cooling device 6 and the means for cooling are not particularly limited. In the present embodiment, a Peltier element is arranged on the outer wall of the melting tank 5.

The shape of the pressurizing device 7 and the means for pressurizing are not particularly limited, but in this example , pressurization is performed by a piston. When such a pressurizing device 7 is provided, when the hydrogen gas generated in the electrolytic bath 5 is dissolved in the dissolving bath 5, the hydrogen gas is pressurized and dissolved in water by the pressurizing device 7, and has a strong reducing property, that is, an oxidation-reduction potential. Low alkaline ionized water is obtained. Here, the dissolution of the gas in water follows the Henry's law and the pressure increases the solubility. In FIG. 3, reference numeral 25 denotes a solenoid valve.

In this embodiment, a heating type deaeration tank 26a provided with the heating device 8 is provided as the deaeration tank 26. That is, in the embodiment, a heater constituting the heating device 8 is wound around the heating type deaeration tank 26a so as to be able to perform electrothermal heating. Here, the heating device 8 is not particularly limited, and may be another heating means such as a gas burner.
In the figure, reference numeral 27 denotes an exhaust unit provided in the degassing tank 26, and the exhaust unit 27 is provided with a solenoid valve. Then
In this embodiment, the alkaline ionized water generated by the electrolysis in the electrolytic cell 1 flows into the heated deaeration tank 26a. Here, alkaline ionized water has a high pH and a large amount of hydrogen gas generated by electrolysis is also dissolved, so it is a highly reducing water.However, if there is a large amount of dissolved oxygen or carbon dioxide in tap water, it may be an interfering substance. And no reducibility is exhibited or the reducibility is not stable. Therefore, if dissolved oxygen or carbon dioxide is driven out of water by heating, a low oxidation-reduction potential will be exhibited. Therefore, in the present embodiment, dissolved oxygen and carbon dioxide are deaerated from the alkaline ionized water by heating in the heating type deaeration tank 26a (in this case, a part of a large amount of hydrogen gas generated by electrolysis is also deaerated. ),
The air is exhausted from the exhaust part 27. However, in this case, since a large amount of hydrogen gas is generated by electrolysis, even if a part of the hydrogen gas is exhausted by the above-described degassing, the hydrogen gas is still contained in the alkaline ionized water.

In FIG. 4, a deaeration tank 26 is provided in place of the multi-stage dissolution tank 5 of FIG. 1 , and in this example , a decompression deaeration provided with a decompression device 9 as the deaeration tank 26. The feature is that the tank 26b is provided. That is, in the embodiment, a decompression pump constituting the decompression device 9 is connected to the decompression type deaeration tank 26b, and the inside of the decompression type deaeration tank 26b is depressurized by a decompression pump constituting the decompression device 9. ,
The air is exhausted from the exhaust part 27. That this
Also in the example , the alkaline ionized water generated by the electrolysis in the electrolytic cell 1 flows into the decompression type degassing tank 26b. Here, alkaline ionized water has a high pH and a large amount of hydrogen gas generated by electrolysis is also dissolved, so it is a highly reducing water.However, if there is a large amount of dissolved oxygen or carbon dioxide in tap water, it may be an interfering substance. It does not show reducibility. Therefore, if dissolved oxygen or carbon dioxide is driven out of water by heating, a low oxidation-reduction potential will be exhibited. Therefore, in this example , the gas is degassed from the alkaline ionized water by reducing the pressure in the decompression type degassing tank 26b (in this case, a part of a large amount of hydrogen gas generated by electrolysis is also degassed), and The exhausted oxygen or carbon dioxide gas is exhausted from the exhaust unit 27.
However, in this case, since a large amount of hydrogen gas is generated by electrolysis, even if a part of the hydrogen gas is exhausted by the above-described degassing, the hydrogen gas is still contained in the alkaline ionized water. It shows the oxidation-reduction potential.

Next, an embodiment of the present invention will be described with reference to FIG. In this embodiment, an oxidation-reduction potential detecting means 10 (that is, an ORP value detecting means) is provided at the most downstream portion of the electrolytic ionic water discharge flow path 4 (in the embodiment, the electrolytic ionic water discharge flow path 4a) to detect the oxidation-reduction potential.

And a redox potential detecting means 1
Based on the result detected by 0, this data is fed back and the control means operates the gas dissolving mechanism to dissolve the gas, or operates the gas degassing mechanism to remove the gas. The redox potential is controlled by controlling the amount of dissolved gas in the electrolytic ionic water by controlling one or a combination of these. Here, the pH of the electrolytic ionic water is adjusted by adjusting the voltage applied to the electrodes 2 and 3 of the electrolytic cell 1 or controlling the flow rate .

FIG. 6 shows an example of this embodiment. In FIG. 6, a degassing tank 26 and a dissolving tank 5
Are provided. In this embodiment, the heating device 8 is provided in the degassing tank 26, and the decompression device 9 is connected to the degassing tank 26 so that the degassing is performed by heating and decompression.
Further, the dissolving tank 5 is provided with a cooling device 6 and a pressurizing device 7, so that the gas is dissolved in water by cooling and pressurizing. Thus, in the embodiment shown in FIG.
First, the oxidation-reduction potential of the electrolytic ion water (alkaline ion water in the example) to be obtained is set. Then, the electrolytic ionic water generated in the electrolytic cell 1 flows through one electrolytic ionic water discharge flow path 4a, and the oxidation-reduction potential detection means 10 detects the oxidation-reduction potential. If the detected value is not the set oxidation-reduction potential, Is controlled to stop the degassing action by the degassing tank 26 by the control means 11 and perform the dissolving action by the dissolving tank 5, or to stop the dissolving action by the dissolving tank 5 and perform the degassing action by the degassing tank 26.
