Abstract

There is provided an apparatus for producing strong alkaline reductive electrolyzed water and acidic water that enables efficient production of electrolyzed water that has excellent washing and sterilizing effects. There is provided an apparatus for producing strong alkaline reductive electrolyzed water and acidic water, which includes an electrolyzer provided with a strong alkaline reductive electrolyzed water-producing chamber, an acidic water-producing chamber and a partitioning membrane, wherein a flow path diffusing device is provided in the electrolyzer, and a gap between the cathode plate and the anode plate of 0.1 mm to 1 mm.

Claims

1. An apparatus for producing strong alkaline reductive electrolyzed water and acidic water, which comprises:

an electrolyzer for producing strong alkaline reductive electrolyzed water and acidic water comprising;

a strong alkaline reductive electrolyzed water-producing chamber having a cathode plate, a raw material water introducing inlet, and a strong alkaline reductive electrolyzed water draining outlet;

an acidic water-producing chamber having an anode plate, a raw material water introducing inlet, and an acidic water draining outlet;

a partitioning membrane for partitioning the alkaline reductive electrolyzed water-producing chamber and the acidic water-producing chamber;

a flow path diffusing device in said electrolyzer for diffusing the raw material water in the alkaline water-producing chamber and the acidic water-producing chamber, respectively; and

said cathode plate and said anode plate being separated by a distance of 0.1 mm to 1 mm.

2. The apparatus according to claim 1, further comprising a circulating path for circulating strong alkaline reductive electrolyzed water or acidic water drained from the strong alkaline reductive electrolyzed water draining outlet or the acidic water draining outlet, and again introducing the water into the electrolyzer;

said circulating path being connected to either the strong alkaline reductive electrolyzed water draining outlet or the acidic water draining outlet.

3. The apparatus according to claim 2, further comprising an electrolyte supplying container filled with one or more additives selected from the group consisting of calcium carbonate, sodium bicarbonate, sodium chloride, ammonium chloride, calcium chloride and potassium chloride;

said electrolyte supplying container being positioned for supplying electrolyte components in the electrolyzer.

4. The apparatus according to claim 3, wherein an additive in the electrolyte supplying container is in the form of a pellet or a solid.

5. The apparatus according to claim 2, further comprising a gas releasing device for releasing oxygen gas and hydrogen gas produced in the electrolyzer to the outside of the apparatus.

6. The apparatus according to claim 2, further comprising a raw material water supplying device for automatically supplying raw material water at the same amount as that of decreased raw material water, when raw material water circulating in the circulating path is decreased.

7. The apparatus according to claim 1, further comprising a direct current electricity source for supplying electricity to the cathode plate and the anode plate.

8. The apparatus according to claim 7, further comprising a voltmeter for measuring the voltage value of the direct current electricity source, and a detecting device for signaling when the voltage measured by the voltmeter is above a set voltage.

9. The apparatus according to claim 1, further comprising an impurity-removing device for removing impurities from the raw material water introduced into the strong alkaline reductive electrolyzed water-producing chamber.
