DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention produces sterilized water containing hypochlorous acid and hypochlorite ions by electrolyzing a sterilized stock solution composed of water, an acid such as sodium chloride and hydrochloric acid. The present invention relates to an electrolytic cell of an electrolytic neutral water generator.

[0002]

2. Description of the Related Art Conventionally, an electrolytic cell of this type of electrolytic neutral water generator is disclosed in Japanese Patent Application Laid-Open No. Hei 6-292892.

Hereinafter, the electrolytic cell of the neutral water generator will be described with reference to FIG. As shown in the figure, a disinfecting stock solution 1 composed of pure water, sodium chloride, and an acid such as hydrochloric acid.
01, an electrolytic cell 105 having a positive electrode plate 103 and a negative electrode plate 104, a power supply device 106 for supplying electricity to the positive electrode plate 103 and the negative electrode plate 104, A liquid passage 108 having a pump 107 for feeding the sterilized stock solution 101 downward.
And a water passage 112 having a cock 111 for adjusting the mixing ratio of the generated electrolytic neutral water 110 above the tap water 109 and the electrolytic cell 105 is provided.
A water discharge passage 114 for discharging sterilized water 113 obtained by diluting the electrolytic neutral water 110 with the tap water 109 from 1 is provided, and a pair of the positive electrode plate 103 and the negative electrode plate 104 are provided at both ends of the electrolytic tank 105. Provided.

[0004]

In such a conventional electrolytic neutral water generator, a pair of plate-like positive and negative electrode plates is provided at both ends of the electrolytic cell. The side surface on which the current flowing between the negative electrode plate is directly and effectively involved is only the inner side surface facing the positive electrode plate and the negative electrode plate, and the positive electrode plate and the There is a problem that the negative electrode plate is not effectively used, and the effective area of the positive electrode plate through which current can flow by effectively utilizing both side surfaces of the plate-like positive electrode plate is increased. There is a demand for an electrolytic cell of a neutral water generator for electrolysis, which can reduce the size of the plate and, consequently, the size of the electrolytic cell and reduce the cost.

[0005] Further, since the positive electrode plate and the negative electrode plate are plate-shaped, a configuration is adopted in which the positive electrode plate and the negative electrode plate face each other from the viewpoint that a current flows between the positive electrode plate and the negative electrode plate. There is a problem that only the space between the inner side surfaces facing the positive electrode plate and the negative electrode plate is effectively utilized, and when the sterilized stock solution flows between the positive electrode and the negative electrode, It is always surrounded by the positive and negative electrodes from any direction, and while keeping the effective area of the negative electrode, through which current can flow, equal to that of conventional plate-shaped electrodes, the size of the electrodes can be reduced, and the size of the electrolytic cell can be reduced, resulting in lower cost. There is a demand for an electrolytic cell of a neutral water generator for electrolysis, which can be used for electrolysis.

[0006] Further, since the sterilized stock solution flows between the positive electrode and the negative electrode only approximately once from below to above, the sterilized stock solution is electrolyzed in almost one pass, and all chloride ions are removed. It is sufficient that hypochlorite is generated by reacting with water by generating chlorine gas by generating chlorine gas, but there is a problem that all chlorine ions may not be converted into chlorine radicals. There is a demand for an electrolytic cell of an electrolytic neutral water generator that can improve the ratio of converting ions into chlorine radicals.

Another problem is that it is necessary to reduce the size of the currently used positive electrode and negative electrode while keeping the same shape without changing the structure and structure of the positive electrode and the negative electrode. There is a demand for an electrolytic cell of an electrolytic neutral water generator that can increase the effective surface area per the same area of the electrode, thereby reducing the size of the electrode and, consequently, the size of the electrolytic cell and reducing the cost.

[0008] Further, when discharging the neutral water for electrolysis, water is discharged from one hole from above the electrolytic tank. However, the neutral water for electrolysis is discharged only in the vicinity of the hole, and it is difficult to discharge water in other places. The concentration of the hypochlorous acid and the hypochlorite ion is not constant when water is discharged when the proportions of the hypochlorous acid and the hypochlorite ion contained in the electrolytic neutral water are different. Therefore, there is a demand for an electrolytic cell of an electrolytic neutral water generator capable of always keeping hypochlorous acid and hypochlorite ions contained in discharged electrolytic neutral water constant.
