Hereinafter, the operation and concentration control method of the electrolytic sterilizing water generating device having the above configuration will be described.

Figure 4 is a flow chart showing a method for producing electrolytic sterilization water according to the electrolytic sterilization water generating apparatus according to the present invention.

As shown in the drawings, the method for producing electrolytic sterilization water according to the present invention is a raw water supply step (S100) that is first supplied to the dilution tank (1) and the storage tank 2 is introduced from the outside, such as tap water or groundwater Proceed. In the raw water supply step (S100), the raw water is introduced into the dilution tank supply process (S120) provided to the dilution tank (1), and the sodium chloride solution manufacturing process (S140) in which the sodium chloride solution is prepared by entering the storage tank (2) Will be implemented.

In the sodium chloride solution manufacturing process (S140), sodium chloride is dissolved in raw water to prepare a sodium chloride solution, and the prepared sodium chloride solution is stored in the storage tank 2. Then, sodium chloride is dissolved in an amount corresponding to solubility in the raw water that is stored in a large amount in the storage tank 2, and becomes a sodium chloride solution having a constant concentration.

Then, the prepared sodium chloride solution is passed through the sodium chloride solution supply step (S200) which is supplied to the dilution tank (1) through the metering pump (3). When the sodium chloride solution is reduced in the storage tank 2 in the sodium chloride solution supply step (S200), the raw water is introduced into the storage tank (2). At this time, the raw water may be configured to be supplied when the sodium chloride solution is reduced below the set value.

In addition, in the sodium chloride solution supply step (S200), the metering pump 3 is controlled by the pulse control unit 4 is adjustable the number of times the sodium chloride solution is supplied to the dilution tank (1). That is, the sodium chloride solution supply step (S200) is controllable to adjust the concentration of sodium chloride in the dilution tank (1), the concentration of the electrolytic sterilization water is controlled later by the sodium chloride concentration of the dilution tank (1).

In addition, the sodium chloride solution supply step (S200) in the metering pump (3) is composed of a plurality of alternating operation so that excessive heat is not generated in the pump.

The raw water supply step (S100) and the sodium chloride solution supply step (S200) may be generated sequentially, but in order to control the sodium chloride concentration in the dilution tank (1) can be selectively changed in order, and thus, simultaneously or vice versa It may happen.

In addition, in the dilution tank 1, the raw water and the sodium chloride solution are mixed, and the mixed water supply step (S300) in which the mixed water is supplied to the electrolytic cell 5 is performed. That is, the sodium chloride solution is introduced in the raw water and the sodium chloride solution supply step (S200) introduced in the raw water supply step (S100) is mixed with each other in the dilution tank (1). This mixed water is mixed for a sufficient time before being supplied to the electrolytic cell 5 so that the sodium chloride concentration of the mixed water is uniform.

 After passing the mixed water supply step (S300), the mixed water is electrolyzed in the electrolytic cell 5 to perform an electrolytic step (S400) which is manufactured as sterilized water. In the electrolysis step (S400), the mixed water introduced from the dilution tank 1 is electrolyzed in the electrolytic cell 5, and is prepared as electrolytic sterilization water containing sodium hypochlorite. In addition, in the electrolysis step (S400), the main controller 8 controls the reaction rate of the mixed water by adjusting the current and the voltage intensity to the electrode 6 of the electrolytic cell 5.

In addition, in the electrolysis step (S400), the cathode and the anode, which are the electrodes 6 of the electrolytic cell 5, are alternately changed in polarity. Therefore, the adsorbate is prevented from occurring on the surface of the electrode to extend the life of the electrolytic cell 5.

After the electrolytic step (S400), the electrolytic sterilization water is discharged through the outlet 7 in the electrolytic cell 5, the user is selectively outside the valve or nozzle provided between the electrolytic cell 5 and the outlet 7 Can be discharged.

Electrolytic sterilization water is prepared in this way, the sodium chloride solution supply step (S200) in the metering pump 3 is controlled by a pulse to adjust the supply amount of sodium chloride, the concentration of the electrolytic sterilization water can be adjusted accordingly.
