Description

Manufacturing apparatus of electrolyzed-reduced water

The present invention relates to an apparatus for producing electrolytic water, and more particularly, to an apparatus for manufacturing electrolyzed water capable of controlling the pH of electrolytic water (hereinafter, abbreviated as pH).

In general, the anode water in the electrolyzed water formed by electrolysis shows a high redox potential because it has an oxidizing property, and the cathode water shows a low redox potential because it has a reducing property.

In general, an electrolyzed water production apparatus for producing alkaline water that can be used for drinking water and acidic water that can be used for cleaning or disinfection and sterilization is an oil-water type that generates acidic or alkaline water by electrolysis in a flowing water state connected to a water supply facility such as tap water. There is a batch method in which electrolysis is carried out in a state where water is retained.

In the flow-type electrolytic water production apparatus, a negative electrode and a positive electrode are installed in a cathode chamber and an anode chamber in which an interior of an electrolytic cell is divided into an ion permeable diaphragm, and a predetermined current is supplied to the cathode and the positive electrode while raw water is continuously supplied into the electrolytic cell. By supplying the raw water is electrolyzed between the diaphragm to produce acidic water and alkaline water.

The disclosed electrolytic water purifier includes a primary electrolytic unit including two electrode chambers in which an electrode chamber in which one positive electrode plate and a negative electrode plate are installed so that water flowing into the inlet of the electrolytic unit is separated into alkaline water and acidic water; Two positive electrode plates and two negative electrode plates are installed by three ion separation membranes so that only the alkaline water generated from the primary electrolytic part is introduced and separated into three kinds of electrolytic ionized waters: strong alkaline water, weak alkaline water and acidic water. It consists of the secondary electrolytic part formed from the electrode chamber.

The electrolytic water purifier configured as described above is composed of three electrodes and three electrode chambers, but since the coin is applied to two adjacent electrodes, neutral water cannot be produced, and strong acidic water and strong alkaline water are difficult to manufacture. .

Electrolytic water generating devices are disclosed in Korean Unexamined Patent Publication Nos. 2003-0064640, 2002-0020163, and Korean Utility Model Registration No. 20-0250783.

The electrolytic water generating devices disclosed in the above patents can produce acidic water and alkaline water using the principle of electrolysis, but since the electrolysis is directly connected to the water pipe or water supply means for supplying the raw water, There is a problem in that pH values of water and alkaline water are non-uniform.

An electrolytic water generation method and apparatus for solving such a problem are disclosed in Korean Patent Registration No. 0133975.

The disclosed electrolytic water generation method includes at least one anode chamber and at least one cathode chamber divided into diaphragms, and a cathode electrode is installed in the cathode chamber, and raw water is continuously supplied to an electrolytic cell in which an anode electrode is installed in the anode chamber. A current is applied between the cathode electrode and the anode electrode, and an electrolyte solution is injected into and added to the raw water, and at least one of the intake amount of the raw water, the discharge amount of the electrolyzed water, and the amount of the aqueous electrolyte solution are measured according to the measured value. The flow rate is controlled, and thus the degree of electrolysis or the amount of generated electrolytic water of at least one of the acidic water of the anode chamber and the alkaline water of the cathode chamber is controlled.

The apparatus for producing electrolytic water controls the electrolyticity and the amount of acidic or alkaline water generated by controlling at least one of the extraction amount of raw water, the electrolytic water discharge amount, and the aqueous solution amount of the electrolyte. Such a method simply controls the supply amount of raw water, the discharge amount of electrolyzed water, the degree of electrolysis, and the amount of production, so that it is difficult to control the pH values of acidic and alkaline water.

The present invention is to solve the problems described above, it is possible to produce acidic water, neutral water and alkaline water, and to provide an electrolytic water production apparatus that is easy to adjust the pH value of acidic and alkaline water.

As a result, the concentration of hydrogen ions increases and acidic water is produced. In the third electrode chamber 23 in which the third electrode 33 is installed, cations of mineral components such as calcium, magnesium, and potassium in raw water are collected, and hydrogen ions obtain electrons by the third electrode 33 to obtain active hydrogen. Is generated and the concentration of hydrogen ions is lowered to generate alkaline water. Neutral water is generated in the second electrode chamber 22 positioned in the middle.

In this process, when the supply of raw water supplied through the raw water supply unit 50 becomes unstable, the pH value of the electrolyzed water generated from each of the electrode chambers 21, 22 and 23 is varied. The pH value of the electrolyzed water can be uniformly controlled by controlling the supply amount of raw water according to the set pH value. That is, the pH value of the electrolyzed water discharged from the electrolytic cell 20 is measured by the measuring sensors 91, 92 and 93 installed in the discharge pipes 61-63, and the measured value by the controller 120. The pH value is set by comparing the set pH value and controlling the flow rate control valve 56a based on the supply amount sensed by the flow rate line. Here, the voltage applied to the first, second, and third electrodes 31, 32, 33 may be adjusted by the controller 110 to adjust the pH value.

In this way, the electrolytic water production apparatus according to the present invention can adjust the pH value of each electrolytic water, that is, acidic water, neutral water and alkaline water to a set value.
