l) An electrolytic water supply device that supplies water (generally tap water) to which an electrolytic aid such as is added, applies a DC voltage between the electrodes, and electrolyzes the water to generate acidic water or alkaline water. Are known. In that case, a strongly acidic water containing, for example, pH 2.7 or less containing sterilizing component hypochlorous acid (HClO) is generated on the plus electrode side, while a pH 11 or less is obtained on the minus electrode side.
The above strong alkaline water is generated. In general, a separation plate (for example, see Japanese Utility Model Publication No. 57-8957) or a separation passage (for example, Japanese Patent Application Laid-Open No. 6-246272) for preventing the generated strong acid water and strong alkali water from mixing with each other in the electrolytic cell.
Separation means is provided, for example, and strongly acidic water and strongly alkaline water are separately taken out of the electrolytic cell and used.

On the other hand, the weakly alkaline water, after generating the strongly acidic water and the strongly alkaline water in the electrolytic cell having no separating means described above, without separating them, that is, while mixing in the electrolytic cell There is known a method of taking out and using as a result weak alkaline water. The reason that the neutral water before the electrolysis is made alkaline by the electrolysis is that chlorine and carbonic acid dissolved in the water are gasified by the electrolysis on the positive electrode side and dissipated into the air. Since such weak alkaline water contains hypochlorous acid generated in the process of electrolysis, it has a bactericidal action in addition to a washing action, and is often used, for example, for cleaning foods in supermarkets.

供給装置を得ることにある。However, the conventional apparatus for producing weak alkaline water has the following problems. (1) Chlorine gas and carbon dioxide gas dissipate in the air, but the amount is small.If the tap water of raw water is slightly acidic at pH 6-7 due to chlorine disinfection, A large amount remains in water without being gasified, and it is not possible to sufficiently generate electrolyzed water on the alkaline side. If the electrolytic power is increased to compensate for this, power consumption will increase, and hypochlorous acid will be generated more than necessary, resulting in increased odor and corrosiveness to metals. By the way, hypochlorous acid is corrosive to metals, and if its concentration is too high, it may corrode food containers and cooking utensils, while if its concentration is low, its sterilizing effect is reduced. (2) Since strongly acidic water and strong alkaline water are all mixed in the electrolytic cell, they cannot be taken out as they are. Therefore, when strongly acidic water or strongly alkaline water is required, an electrolyzed water supply device for separating and extracting these must be separately provided. (3) In the conventional weak alkaline water generator, the main body and the accompanying electrolytic water tank, supply pump, watering hose, etc. are supplied separately, so it is troublesome to combine them as a system at the installation site, and it is difficult to move It is. Therefore, an object of the present invention is to solve the above problems, to obtain a properly adjusted weakly alkaline water, to obtain strongly acidic water and strongly alkaline water at the same time, and to use electrolytic water which is convenient for installation and handling. It is to obtain a supply device.

It is based on the new finding that it is better to separate them once, take them out separately, and mix them again outside the electrolytic cell, instead of mixing them. That is, the present invention provides an electrolytic cell in which a positive electrode and a negative electrode are installed facing each other, supplies water with an electrolytic aid added thereto, and applies a DC voltage between the electrodes to electrolyze the water, In the electrolyzed water supply device for generating strong acidic water on the positive electrode side and generating strong alkaline water on the negative electrode side, the strong acidic water and the strong alkaline water are separated and separately taken out of the electrolytic cell. In addition, the strongly acidic water and the strongly alkaline water are mixed with each other outside the electrolytic cell to generate weakly alkaline water.

中に散逸される。[0007] When weakly alkaline water is obtained by mixing strongly acidic water and strongly alkaline water, they can be mixed as they are in the electrolytic cell or mixed after being taken out of the electrolytic cell. Sounds like a thing. However, the inventors of the present application have found that mixing outside of the electrolytic cell leads to better dissipation of chlorine gas and carbon dioxide gas generated on the acidic water side. Considering the reason, if water on the acidic water side and water on the alkaline water side were mixed in the electrolytic cell, the generated chlorine gas and carbon dioxide gas diffused into the electrolytic cell and were newly supplied. The part that is dissolved again in the water increases and the part that is carried out of the electrolytic cell together with the weak alkaline water decreases, whereas the strong acidic water and the strong alkaline water It is considered that when they are separated from each other and taken out separately, chlorine gas and carbon dioxide gas on the acidic water side are enclosed together with the strongly acidic water by the separating means, and most of them are carried out of the tank. The chlorine gas and carbon dioxide gas carried out together with the strongly acidic water are dissipated into the air from the outlet when the strongly acidic water is mixed with the strongly alkaline water and discharged as weakly alkaline water.

ることにより適正に調整することが可能である。[0008] By the way, alkaline water is suitable for washing foods and maintaining freshness, but has an action of dissolving fats and proteins.
If the alkalinity is too high, the quality of the ingredients, such as flavor and appearance, is impaired. Therefore, weak alkaline water having a pH of 7 <pH <9 is suitable for uses such as food cleaning. On the other hand, hypochlorous acid has a bactericidal action, but if this concentration is too high, an off-flavor will remain,
Hypochlorous acid concentration is 10 ~ 30pp because it corrodes metal
m, more preferably 15 to 25 ppm. According to the above-described invention, weak alkaline water can be generated which is sufficiently leaned toward the alkali side without increasing the electrolyticity.
There is no danger of excessively generating hypochlorous acid. The pH and the concentration of hypochlorous acid can be properly adjusted by controlling the electrolysis current according to the electric conductivity of water.

In addition, strong acid water is required to effectively sterilize cooking equipment. That point,
In the present invention, the strongly acidic water and the strongly alkaline water are separated and taken out from the electrolytic cell, so that they can be used individually as needed before mixing. For this purpose, a weak alkaline water tank for storing the weak alkaline water is provided, and a switching valve for individually extracting the strong acidic water or strong alkaline water before mixing is provided in the piping connecting the weak alkaline water tank and the electrolytic cell.

れている。Table 1 shows the results obtained by measuring the disinfection effect using weak alkaline water according to the apparatus of the present invention. The test conditions are as follows. Take a test tube with weak alkaline water having a pH of 8 and a hypochlorous acid concentration of 19 ppm as test water, and place in a thermostat at 20 ° C in advance. Inoculate test water into test water (10 5 to 10 6 CUF
/ ml) and mix for 10 seconds, 30 seconds, 1
After 10 minutes, add sterile 3% sodium thiosulfate for 100 minutes.
Add μl to neutralize residual chlorine. Immediately 10-fold serial dilution (
Stock solution to 10 4 times) that the 0.1ml of each diluted stage cultured in trypticase soy agar and defined media, count the generated colonies. From these results, a good sterilization effect was confirmed (<10 indicates that no bacteria were detected in Table 1). That is, while this weak alkaline water has a moderate sterilizing power,
Since the concentration of hypochlorous acid is low, the corrosiveness to metals is also suppressed.

ま利用することが可能である。In each of the above embodiments, the strongly acidic water and the strongly alkaline water generated in the electrolytic cell 2 are separated and taken out of the electrolytic cell 2, so that chlorine gas or The gas is directly carried out of the electrolytic cell 2 together with the strongly acidic water. Therefore, as in a conventional apparatus in which strongly acidic water and strongly alkaline water are mixed in the electrolytic cell 2, chlorine gas or carbon dioxide gas immediately after generation diffuses into the electrolytic cell 2 and returns to newly supplied water. Most of the generated chlorine gas and carbon dioxide gas are taken out of the tank and dissipated without being dissolved, and the alkalinity of the weak alkaline water increases. In addition, strong acid water and strong alkaline water separately taken out,
The three-way valves 11 and 12 can be used as needed by switching.
