Apparatus for producing electrolytic reduced water and control method thereof

An apparatus for producing electrolytic reduced water, the apparatus comprising:

• a water purifying unit configured to generate purified water by filtering water;
• an electrolytic reduced water generating unit comprising a first electrode and a second electrode that have different polarities, and configured to generate reduced water containing a dissolved hydrogen gas by performing electrolysis on the purified water through the first electrode and the second electrode;
• a water storage unit configured to store the received electrolytic reduced water;
• a power supply unit configured to apply a different polarity of electricity to each of the first electrode and the second electrode;
• a flow rate detecting unit configured to detect a flow rate of purified water discharged from the water purifying unit;
• a control unit configured to determine a point of time for switching polarities of the first electrode and the second electrode based on the flow rate of purified water, and configured, if it is determined that the points of time for switching the polarities of the first electrode and the second electrode is reached, to control an operation of the power supply unit such that the polarities of the first electrode and the second electrode are switched.
