Referring to the operation of the ionized water production apparatus consisting of this configuration and the ionized water production method as follows. First, the ionized water production method of the present invention is a raw water purification step of removing foreign matter from raw water, an underwater discharge step of discharging the purified raw water in the discharge tank 20 to form discharge ionized water, and the discharge ionized water in the electrolytic cell 70 The electrolysis step consists of an electrolysis step that separates acidic and alkaline water.

The raw water purification step is performed by passing raw water, such as tap water or ground water, through the pretreatment filter unit 10 as shown in FIG. 2, while the raw water passes through the block carbon filter 11 of the pretreatment filter unit 10. , Organic chemicals and the like are adsorbed and removed, and various bacteria and impurities are removed while passing through the hollow fiber membrane filter 12. The purified raw water is accommodated in the discharge vessel 20 through the inlet 21 of the discharge vessel 20.

Subsequently, in the underwater discharge step, by applying power to the discharge cells 30 of the discharge vessel 20 to discharge the water under water, the received raw water is brought into an underwater plasma ion state to form discharge ionized water, that is, as shown in FIGS. 2 and 3. Likewise, when power is applied to the discharge wire 32 of the discharge cell 30 to cause a discharge between the discharge plate 31 and the discharge wire 32, the raw water introduced through the inlet 21 is instantaneously cathode. ) Vaporizes at a high temperature (about 100 degrees to several thousand degrees) and becomes an underwater plasma ion state.

This results in continuously vaporized underwater discharge ionized water containing low specific gravity anion gases (hydrogen ions, chlorine ions, oils, detergents) and high specific gravity cationic materials (metals, minerals, etc.). Underwater discharge active oxygen generated at this time has a strong bactericidal power and generates a metal oxide within a short time. However, minerals (Na, Ca, Mg, K) are dissolved in water and preserved.

Raw water introduced into the discharge vessel 20 through this process is converted into discharge ionized water through the discharge cell 30 to generate active ions and hydrogen gas. Active ions generated in the discharge tank 20 oxidizes bacteria and organic matter contained in the raw water, changes the structure of the inorganic material, and hydrogen ions and chlorine ion gas generated in the discharge tank 20 are discharged from the discharge tank 20. It is filled in the empty space. This anion gas serves to prevent the growth of bacteria.

Driving the pump 61 installed in the discharge tank 20 forcibly supplying the discharge ionized water in the discharge tank 20 through the inlet 71 of the electrolytic cell 70, and at the same time, the negative terminal 72 and the positive terminal ( 73) When the electric current is discharged by passing a current therebetween, alkaline ions such as calcium ions, magnesium ions, potassium ions, sodium ions and the like are collected on the negative electrode terminal 72 to form alkaline water, and on the positive terminal 73 side. Acidic ions, such as chloride ions and sulfur ions, become acidic water, and the acidic water and the alkaline water are separated and discharged through the alkaline water outlet 75 and the acidic water outlet 76 of the electrolytic cell 70 to produce ionized water. .

As described above, the present invention does not directly electrolyze raw water in the electrolytic cell 70, but first forms discharge ion water by the underwater discharge action in the discharge cell 20, and then supplies the discharge ion water to the electrolytic cell 70 to electrolysis. As a result, the discharge ionized water can be electrolyzed at lower voltage and current to directly electrolyze raw water, thereby separating the acidic water and the alkaline water.

The table below shows the voltage and current difference applied to the electrolyzer 70 when electrolyzing raw water and discharge ionized water, and as can be seen from the table, lower voltage and current than when directly electrolyzing conventional raw water. As a result, an alkaline water having a higher ORP value than PH can be produced.
