Composed. The electrolytic cell is classified into two types depending on its structure. One is, for example, Shokai Sho 5

Of the above-mentioned two methods, the latter continuous method is also mainstream to add a water purification function because it is convenient because ion water can be obtained instantly.

As it is, the water supplied from the inlet of the electrolytic cell is electrolyzed while passing through the cathode chamber and the anode chamber partitioned by the electrolytic diaphragm, and the alkaline ionized water is fed from the cathode chamber side of the electrolytic cell and the acidic ionized water is fed from the anode side. It is configured to generate. Further, unlike the batch type, the continuous type ion water purifier further efficiently produces alkaline ionized water having a large pH (index indicating hydrogen ion concentration) or acidic ionized water having a small pH, or downsizing, in a short time. In order to prevent this, various flowing water type electrolytic cells have been proposed.

【発明が解決しようとする課題】しかしながら、本発明
者が研究実験した結果、電解槽の開発には以下の２つの
課題があることが解った。However, as a result of the research and experiment conducted by the present inventor, it was found that the development of the electrolytic cell had the following two problems.
【０００７】１つめの課題は、最近、消費者の飲料水の

い。[0007] The first problem is trihalomethane, which has recently been attracting attention due to the increased awareness of consumers regarding the safety of drinking water. The ion-stream water purifiers having a water purifying function have become the mainstream, but the safety of trihalomethane in the electrolytic cell has not yet been examined.
【０００８】本発明者は電解槽部でのトリハロメタンの

験確認したところ表１に示すようにトリハロメタンの生
成が起こることが確認された。The inventor of the present invention paid attention to the possibility of trihalomethane formation in the electrolytic cell part, and conducted experimental confirmation in a batch system using a beaker, and as shown in Table 1, it was confirmed that trihalomethane formation occurred.
【０００９】[0009]
【表１】 [Table 1]

がトリハロメタンが生成することが確認された。Also, in an experiment using a flowing water type (continuous type) electrolytic cell, as shown in Table 2, it was confirmed that trihalomethane was produced although it was slight depending on the structure.
【００１１】[0011]
【表２】 [Table 2]
【００１２】このトリハロメタンの生成メカニズムは、
次のハロホルム反応によるものが代表的反応機構であ

The following reaction mechanism is based on the haloform reaction.

【００１４】そして上記の加水分解反応は水酸化物イオ

されてトリハロメタンが生成される。The above-mentioned hydrolysis reaction is promoted by the use of hydroxide ion as a catalyst as shown in the following reaction formula. That is, the more alkaline the reaction is, the more accelerated the hydrolysis is to produce trihalomethane. .
【００１５】[0015]
【化２】 [Chemical 2]
【００１６】上記のことから、電解槽の陰極室において

ことによるものであり、その結果、陰極室で前駆物質が
次亜塩素酸と反応し、さらに陰極で生成するＯＨイオン
が反応を促進することでトリハロメタンが発生すること
が解った。From the above, the reason why trihalomethane is generated in the alkaline ionized water generated in the cathode chamber of the electrolytic cell is that chlorine generated in the anode chamber (hypochlorous is also generated by the equilibrium reaction of chlorine) is the cathode. It is due to mixing into the chamber through the diaphragm, and as a result, the precursor reacts with hypochlorous acid in the cathode chamber, and OH ions generated at the cathode accelerate the reaction to generate trihalomethane. I understand.

アルカリ表示されるという不都合が発生する。Another problem is a phenomenon found in water using groundwater containing a large amount of carbonic acid as a water source. In producing weak acidic ionized water, so-called astringent water, in the anode chamber, immediately after leaving the electrolytic cell. This water has a pH of 7.
Although it shows an alkalinity of about -8, the phenomenon that water received in a cup or the like returns to a weak acidity of about pH 6 with time is observed. Due to this phenomenon, when adding a pH sensing function to the water distribution route, the pH of the generated cup water is
Although pH is acidic, there is a disadvantage that the sensed pH is displayed as alkali.

１０以上の強いアルカリの水が生成される。The situation in which such an alkaline display of pH occurs is as follows. (1) Not found in tap water that uses river water as a water source, but in water with a high carbonic acid content such as tap water that uses groundwater as a water source. (2) When generating alkaline ionized water, the discharge side of the electrolytic cell is the cathode chamber and the drain side is the anode chamber. If the direction of application to such an electrode is the forward direction, the discharge water is generated when weakly acidic ionized water is generated. side is the anode chamber, pH only when the drainage side is performed in the reverse direction by reversing the polarity of the electrodes so that the negative electrode chamber, for generating a weak acid ion water with application of the reverse
You can see the alkali display. On the other hand, when the water is applied in the forward direction, the drainage side is acidic ionized water, but this acidic ionized water does not show an alkaline indication of pH. (3) Since the ionized water on the drainage side becomes discarded water, generally, by narrowing the piping flow path on the outlet side on the drainage side, the amount of water discharged from the water discharge side is increased to minimize the amount of drainage water from the drainage side. ing. As a result, the acidic ionized water on the drainage side when applying the forward direction is strongly acidic water with a pH of 4 or less, and the alkaline ionized water on the drainage side when applying the reverse direction has
Strong alkaline water of 10 or more is produced.

酸成分の緩衝作用が働き、From the above, the present inventor has found that the cause of the phenomenon of alkaline display of pH is that strong alkaline ionized water (water is generated in the electrode chamber on the drainage side (in this case, the cathode chamber) is generated in the reverse applied state. It was found that the oxide ion OH − ) permeates to the water discharge side through the diaphragm and mixes with the acidic ionized water, and the principle is as follows. That is, when there is no influence of the carbonic acid component, even if a small amount of OH − is mixed in, the neutralization reaction of OH − + H + → H 2 O occurs instantly, so that the alkali display of pH is not observed. However, when there are many carbonic acid components, the buffering action of the carbonic acid components shown by the following formula works,

One of the objects is to provide a continuous ion water purifier in which pH is not displayed as an alkali when weakly acidic ionized water is generated when a pH sensing function is added to a water distribution path.
