According to an embodiment of the present invention, the power control unit 150 may individually adjust the amount of power supplied to the two metal plates of the first electrode 111a, respectively, during the generation of the electrolytic sterilization water.

By separately controlling the two metal plates in this way, it becomes possible to more precisely control the operation rate of the electrolysis unit.

According to an embodiment, it is possible to control the supply of power to one of the two metal plates by an On/Off method, and to variably control the supply of power to the other one through a PWM signal or the like. In this case, the control range of the electrolysis operation rate can be further expanded and more precisely controlled according to a change in flow rate or a change in treatment tools. That is, when it is necessary to minimize the electrolysis operation rate, the power supplied to the single metal plate may be turned off, and in the opposite case, the power may be turned on.
