Abstract

The present invention provides an electrolyzed water producing apparatus capable of efficiently producing electrolyzed water containing hypochlorous acids and of being installed stably. An electrolyzed water producing apparatus of the present invention includes: an electrolyzing section, the electrolyzing section including (i) an electrode pair having a positive electrode and a negative electrode facing the positive electrode and (ii) a no-diaphragm-type electrolytic solution channel between the positive electrode and the negative electrode, the electrode pair being inclined in such a manner that the positive electrode is positioned higher than the negative electrode, the electrolytic solution channel allowing an electrolytic solution to flow into the electrolytic solution channel from below and allowing electrolyzed water, which has been produced by electrolyzing the electrolytic solution with use of the electrode pair and which contains hypochlorous acids, to flow out from an upper portion of the electrolytic solution channel, the electrode pair being inclined at an angle of not less than 10 degrees and not more than 85 degrees relative to a vertical direction.

First claim

1 . An electrolyzed water producing apparatus, comprising:
an electrolyzing section, the electrolyzing section including (i) an electrode pair having a positive electrode and a negative electrode facing the positive electrode and (ii) a no-diaphragm-type electrolytic solution channel between the positive electrode and the negative electrode, the electrode pair being inclined in such a manner that the positive electrode is positioned higher than the negative electrode, the electrolytic solution channel allowing an electrolytic solution to flow into the electrolytic solution channel from below and allowing electrolyzed water, which has been produced by electrolyzing the electrolytic solution with use of the electrode pair and which contains hypochlorous acids, to flow out from an upper portion of the electrolytic solution channel, the electrode pair being inclined at an angle of not less than 10 degrees and not more than 85 degrees relative to a vertical direction.

2 . The electrolyzed water producing apparatus according to claim 1 ,
wherein the electrode pair is inclined at an angle of not less than 50 degrees and not more than 80 degrees relative to the vertical direction.

3 . The electrolyzed water producing apparatus according to claim 1 ,
wherein the positive electrode and the negative electrode each have a substantially rectangular electrode surface and are each oriented in such a manner that a first lengthwise end of the electrode surface is positioned higher than a second lengthwise end of the electrode surface.

4 . The electrolyzed water producing apparatus according to claim 3 ,
wherein the electrode pair is configured such that a ratio of (i) a distance between the positive electrode and the negative electrode to (ii) a length of the electrode surface is within a range of 1:100 to 1:10.

5 . The electrolyzed water producing apparatus according to claim 1 ,
wherein the negative electrode is a Ti electrode.

6 . The electrolyzed water producing apparatus according to claim 1 ,
wherein the electrolytic solution includes an aqueous solution containing an acidic substance and an alkali metal chloride.

7 . The electrolyzed water producing apparatus according to claim 1 , further comprising:
a diluting section configured to dilute the electrolyzed rater, which is produced by the electrolyzing section.

8 . The electrolyzed water producing apparatus according to claim 7 , further comprising:
a cooling section configured to cool the electrode pair, wherein the cooling section cools the electrode pair with use of water intended for dilution of the electrolyzed water.

9 . The electrolyzed water producing apparatus according to claim 1 , further comprising:
an electrolytic solution supplying section; and a detecting section, wherein the detecting section includes a detection electrode for measuring an electrical property of the electrolytic solution, the electrolyzed water, or a mixture of the electrolytic solution and the electrolyzed water and is configured to detect (i) a decrease in an amount of the electrolytic solution which amount is supplied to the electrolyzing section or (ii) a decrease in an amount of the electrolyzed water which amount is discharged from the electrolyzing section.

10 . The electrolyzed water producing apparatus according to claim 1 , further comprising:
an electrolytic solution supplying section; and a detecting section, wherein the detecting section is configured to, on a basis of an amount of change over time in a relationship between a current flowing through the electrode pair and a voltage applied to the electrode pair, detect a decrease in an amount of the electrolytic solution which amount is supplied to the electrolyzing section.
