Acidic water is water containing a relatively large amount of hydrogen ions, and alkaline water is water containing a relatively large amount of hydroxyl ions. At this time, if an ion exchange diaphragm is provided between the electrodes, hydrogen ions move to the electrode to which electricity is applied, and hydroxyl ions move to the electrode to which the electricity is applied.

Hereinafter, an electrolytic water generating device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an electrolytic water generating device according to the present invention, FIG. 2 is a cross-sectional view of an electrolyte supply unit in FIG. 1, and FIG. 3 is an exploded perspective view of the electrolyte supply unit of FIG. 2.

As shown, the electrolyzed water generating apparatus according to the present invention, at least one or more electrolyzer 10 for generating electrolyzed water, a raw water supply line 20 for supplying raw water to the electrolyzer, and the electrolyte to the raw water supply line 20 And a power supply 40 for applying a direct current voltage to the first and second electrode plates 13 and 17 of the electrolytic cell 10 and selectively reversing the direct current voltage. do.

The electrolytic cell 10 is separated into the first chamber 12 and the second chamber 16 by the ion diaphragm 11. The first chamber 12 is connected to the first discharge line 14 in which the first electrode plate 13 is installed and the generated electrolytic water is discharged. The second chamber 16 is provided with a second electrode plate 17 and a second discharge line 18 through which the generated electrolytic water is discharged is connected. That is, the first electrode plate 13 is provided on one side of the ion diaphragm 11, the second electrode plate 17 is provided on the other side, and the electrolyzed water generated by the first and second electrode plates 13 and 17 is ionized. The diaphragm 11 is separated into acidic and alkaline water.

The raw water supply line 20 supplies raw water to the first and second chambers 12 and 16, respectively, and is connected to the electrolyte supply unit 30 to be described later.

As shown in FIGS. 2 and 3, the electrolyte supply unit 30 has an inlet 32 through which raw water is introduced at one lower end thereof, and an outlet 33 connected to the raw water supply line 20 at another lower end thereof. Is formed in the housing 31, the electrolyte cartridge 35 selectively filled in the housing 31 and filled with the electrolyte N, and the electrolyte cartridge 35 in the housing 31 so that the electrolyte cartridge 35 is completely received into the housing 31. And a lid 37 that is screwed on. To this end, each of the lid 37 and the housing 31 is formed with a screw portion (37a) (31a) that is screwed together. By this structure, the user can easily exchange the electrolyte cartridge 35 after opening the lid 37 from the housing 31.

The electrolyte cartridge 35 has a tubular shape in which two or more holes 36 are formed at a lower end thereof, and the holes 36 are formed at positions corresponding to the inlet 32 and the outlet 33 of the housing 31. do. The electrolyte cartridge 35 is filled with an electrolyte N, and the electrolyte is supplied to the raw water via the housing 31. Examples of the electrolyte include NaCl, HCl, KCl and the like, and NaCl is used in this embodiment.

When the electrolyte cartridge 35 is not installed in the housing 31, the raw water passing through the housing 31 is directly transferred to the electrolytic cell 10 through the raw water supply line 20, and the weakly electrolyzed water (weak acid water, weak alkaline water). ).

When the electrolyte cartridge 35 is installed in the housing 31, the electrolyte N is gradually supplied to the raw water via the housing 31. Then, the electrolyte N is transferred to the electrolytic cell 10 through the raw water supply line 20 to contribute to the generation of strong electrolytic water (strong acidic water, strong alkaline water).

The power supply 40 is for applying an appropriate DC voltage to the first and second pole plates 13 and 17 of the electrolytic cell 10, and the current flowing through the first and second pole plates 13 and 17 is greater than or equal to a predetermined value. When the sensor 41 detects this, the voltage reversing unit 43 receives the signal generated by the sensor 41 and reverses the DC voltage flowing through the first electrode plate 13 and the second electrode plate 17. The control unit 45 is organically connected to the sensor 41 and the voltage reversing unit 43.

The electrolytic water generating apparatus having the above-described structure will be described as follows for generating weakly electrolyzed water (weakly acidic water and weakly alkaline water) or strongly electrolyzed water (strongly acidic and strong alkaline water).

(a) when generating weakly electrolyzed water (weakly acidic and weakly alkaline water),

When generating weak electrolyzed water, the electrolyte is not supplied to the raw water flowing into the electrolytic cell 10, a positive voltage is applied to the first electrode plate 13, and a − voltage is applied to the second electrode plate 17. The voltage applied between the first and second electrode plates 13 and 17 was set in the range of 4.5V to 30V. In this case, depending on the voltage, the current value flowing between the first electrode plate 13 and the second electrode plate 17 is about 0.25A to about 3.3A. In this state, weakly acidic water is produced in the first chamber 12 in which the first electrode plate 13 is located, and weakly alkaline water is generated in the second chamber 16. The weakly acidic water and the weak alkaline water are discharged to the outside through the first discharge line and the second discharge line for use by the user.

The pH of the weakly acidic water produced in the first chamber 12 is in the range of 4 to 6, and the ORP is about 800 mV. Such weakly acidic water has higher anion content than chlorine ion and sulfate ion than raw water, and has an astringent effect, so that it can be used for beauty care such as lotion and face wash.

The pH of the weak alkaline water produced in the 2nd chamber 12 has a range of 8.5-10, and ORP has about -50-250 mV. The weak alkaline water has a higher content of cations such as calcium ions, magnesium ions, potassium ions and sodium ions than raw water, and is effective in preventing gastrointestinal abnormal fermentation, chronic diarrhea, constipation improvement, antacids, and excessive gastric acid.

(b) when generating strong seawater (strongly acidic and strong alkaline water),

When generating strong electric water, the electrolyte must be supplied to the raw water flowing into the electrolytic cell (10). That is, the electrolyte cartridge 35 is to be inserted into the housing 31 so that the electrolyte is dissolved into raw water.

When the raw water containing the electrolyte flows into the electrolytic cell 10, the current value flowing between the first and second electrode plates 13 and 17 is much larger than the raw water containing no electrolyte. In this embodiment, when the voltage applied between the first and second electrode plates 13 and 17 is in the range of 4.5V to 30V, the current value flowing between the first electrode plate 13 and the second electrode plate 17 is It became about 8.5A-10A.

When the current flowing between the first and second electrode plates 13 and 17 is 7A or more, the sensor 41 detects this and transmits a signal for operating the voltage reversing unit 42 to the controller 45. Then, the controller 45 reverses the polarity of the voltage flowing through the first and second electrode plates 13 and 17.

In this state, strong acidic water and strong alkaline water are generated. In contrast to the generation of weak electrolytic water, strong alkaline water is generated in the first chamber 12 and strong acidic water is generated in the second chamber 16. The strong acidic water produced under the above voltage and current conditions has a pH of 3 or less, an effective chlorine concentration of 20 ppm or more, and an ORP of 1000 mV or more. Strong acidic water is generated in the second chamber 16 and discharged to the outside through the second discharge line. The strong alkaline water is generated in the first chamber 12 and then discharged to the outside through the first discharge line.

The reason for reversing the voltages applied to the first electrode plate 13 and the second electrode plate 17 when generating the strong electric water is to prevent the first and second electrode plates 13 and 17 from fatigue. That is, when generating weak electrolyzed water, a positive voltage is applied to the first electrode plate 13 and a negative voltage is applied to the second electrode plate 17 so that weakly alkaline water is generated in the second chamber 16 in the first chamber 12. do. However, when generating strong electric water, if strong acidic water is generated in the first electrode plate 13 and strong alkaline water is produced in the second electrode plate 17, similarly to the weak electric water, each of the first and second electrode plates 13 and 17 is formed. Fatigue accumulates, shortening the life of the plate. Therefore, the positions of generation of acidic and alkaline water generated during weak electrolytic water generation and strong electrolytic water generation are changed so that the fatigue degree of the electrode plate is not accumulated.

As such, when the electrolyte is supplied from the electrolyte supply unit 30 to the raw water in order to generate the strong electric water, a current value flowing between the first and second electrode plates 13 and 17 is increased, and the sensor 41 detects this. By notifying the control unit 45, the control unit 45 operates the voltage reversing unit 42. Then, the electrodes applied to the first and second electrode plates 13 and 17 are automatically switched. That is, when generating weak electrolytic water and generating strong electrolytic water, the service life of the first and second electrode plates 13 and 17 can be extended as much as possible by reversing the voltage applied to the first and second electrode plates.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.

As described above, according to the electrolytic water generating device according to the present invention, the electrolyte is selectively added to the raw water flowing into the electrolytic cell, and then, by reversing the voltage applied to the first and second electrode plates, the weak electrolytic water and the strong electrolytic water are effectively generated. In addition, there is an effect that can further extend the service life by reducing the fatigue of the first and second electrode plates accordingly.
