BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electrode structure unit for a sterilizing / reducing water electrolyzer, and an electrode module including the sterilizing / reducing water electrolytic bath,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode structure unit, and more particularly, to an electrode structure unit for a sterilizing / reducing electrolytic cell and an electrode module including the electrode structure unit.

Environmental pollution such as atopy is increasing as the pollution of air or soil becomes worse, but the interest of health is getting bigger due to the spread of wellness. In addition, due to the improvement in living standards, there is an increasing need to use not only drinking water but also cleaning and other living water for sterilization. Therefore, in recent years, development of a sterilization / reduced water production apparatus has been promoted.

Sterilization and Reduction Water In the sterilizing / reducing water electrolyzer using electrolysis of water in the apparatus, a positive electrode plate and a negative electrode plate are installed in the main body, and a positive electrode plate and a negative electrode plate are connected to the positive electrode and negative electrode of the external power source, respectively. When raw water is injected into the main body and then power is applied, oxygen can be obtained by the oxidation reaction at the anode, and hydrogen can be obtained by the reduction reaction at the cathode.

Plate-shaped or mesh-shaped electrodes are generally used for such a sterilized / reduced-water electrolytic cell. In the case of the above-mentioned plate-shaped or mesh-type electrode, the initial electrolytic force is high when the gap between the positive electrode and the negative electrode is close to each other, but as time passes, the electrolyzed bubbles are entangled with each other to form a large bubble layer. Such a bubble layer can damage the electrode and degrade the electrolysis efficiency. On the contrary, when the distance between the positive electrode plate and the negative electrode plate is long, the electrolytic power is low and the electrolytic efficiency is lowered.

The prior art Korean Patent Laid-Open Publication No. 2006-0021968 (hereinafter referred to as "prior patent") relates to a method for producing ionized water and an apparatus for producing ionized water, which are installed inside the first and second electrode chambers 21 and 22 The first and second electrodes 31 and 32 may be formed by plating or coating a plate member made of a metal, an alloy, a metal oxide, or the like, and a conductive material such as sintered carbon. Shape or a punching plate.

In the case of an electrode having a plate shape such as a plate shape or a punching plate as in the prior art, electrolysis is actively performed only at a corner of the plate when applied to a sterilized / reduced water electrolyzer. Therefore, uniform electrolysis does not occur throughout the electrodes, and as a result, damage is caused to the edges of the electrode over time, which causes a short life span.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are assigned to the same or similar components throughout the specification.

The present invention will now be described more specifically with reference to the following examples. However, the following examples should not be construed as limiting the scope of the present invention, and should be construed to facilitate understanding of the present invention.

1 is a plan view of an electrode structure unit for a sterilizing / reducing water electrolyzer according to an embodiment of the present invention.

Referring to FIG. 1, an electrode structure unit for a sterilizing / reducing water electrolyzer according to an embodiment of the present invention includes a first electrode 10 and a second electrode 20.

The first electrode 10 may be an oxidizing electrode. The first electrode 10 has a ring shape having a predetermined diameter R1 and is a closed curve whose cross section has no line segment. Accordingly, the oxidation or reduction reaction can be prevented from being biased at a specific portion, since it does not have an edge over the entire surface of the first electrode 10, and power supply is uniformly formed over the entire electrode, And even though corrosion occurs over time, corrosion is uniformly generated over the entire surface of the electrode, so that the life of the electrode is prolonged.

The second electrode 20 may be a reducing electrode. As the power is supplied to the second electrode 20, a return gas and reduced water are generated. The second electrode 20 is a closed curve having the same center point on the same plane as the first electrode 10 and having no cross-sectional line segment, and has a diameter R2 larger than that of the first electrode 10 Ring shape. Thus, since the first electrode 10 does not have an edge over the entire surface, it is possible to prevent the oxidation or reduction reaction from being biased at a specific portion. In addition, since the power supply is uniform over the entire electrode, the effect of electrolyzing water molecules is improved, and even though corrosion occurs over time, uniform corrosion occurs across the entire surface of the electrode, thereby prolonging the life of the electrode have.

The diameter of the inner circumferential surface of the second electrode 20 may be larger than the diameter of the outer circumferential surface of the first electrode 10 in order to secure space for sterilizing and reducing electrolysis between the first electrode 10 and the second electrode 20. [ Diameter.

On the other hand, in the case of the electrode structure unit for a sterilization / reducing water electrolyzer, the closer the distance between the two electrodes is, the more excellent the electrolysis effect of water molecules is. However, in the case of a conventional plate-shaped electrode, as the distance between the electrodes becomes closer, the degree of damage to the electrode becomes larger and causes a failure, and therefore, it has to be maintained at a predetermined distance. However, in the case of the electrode for a sterilizing / reducing water electrolyzer according to an embodiment of the present invention, the first electrode 10 and the second electrode 20 have a ring shape, and the cross- Even if the distance between the first electrode 10 and the second electrode 20 is arranged close to each other, uniform electrolysis occurs over the entire surface of both electrodes, thereby improving the stability of the electrode. Accordingly, since the distance between the electrodes can be arranged closer to that of the plate-shaped electrode, the water molecule electrolytic resolution can be improved, and since the distance between the electrodes is close to each other, operation at low voltage is possible.

Specifically, the distance between the first electrode 10 and the second electrode 20 may be 0.5 mm to 2 mm. If the distance between the first electrode 10 and the second electrode 20 is less than 0.5 mm, the electrode may be damaged. If the distance is more than 2 mm, the water-electrolytic resolution may be deteriorated. It is most preferable that the distance between the first electrode 10 and the second electrode 20 is 1.0 mm.

The first electrode 10 and the second electrode 20 may have a circular cross section. When the cross section of the first electrode 10 and the second electrode 20 is circular, power supply is most uniformly provided over the entire surface of the electrode, so that the effect of electrolyzing water molecules can be further improved.

The first electrode 10 and the second electrode 20 may include at least one selected from the group consisting of titanium (Ti), platinum (Pt), and iridium (Ir). For example, the first electrode 10 and the second electrode 20 may be plated with platinum (Pt). Platinum (Pt) plated electrodes can reduce the manufacturing cost of the electrode and have an excellent stability of the electrode.

As the reduced water is simultaneously generated between the first electrode 10 and the second electrode 20, the sterilization and reduction proceeds at the same time, so that the sterilizing power between the first electrode and the second electrode is higher than that of the electrolytic cell including the separation membrane And reducing power.
