Abstract:
A production system of electrolyzed water including an electrolyzer having a pair of electrode chambers subdivided by a partition membrane and supplied with treatment water from an external water supply source to continuously electrolyze the water for producing alkaline water and acid water;a pair of discharge conduits connected to the electrode chambers and provided with a faucet at their outlet ends respectively, a pair of drain conduits respectively bifurcated from the discharge conduits at upstream of the faucets and each provided with a dram valve to be opened and closed; and a control circuit including control means for closing the drain valve of the drain conduit bifurcated from the discharge conduit opened at its faucet when either one of the faucets or both the faucets was opened; wherein the control circuit includes determination means for determining whether or not either one of the faucets was opened while the other faucet is closed so that the electrolyzed water is discharged only through the discharge conduit opened at its faucet, and drain control means for intermittently opening and closing the drain valve of the drain conduit bifurcated from the discharge conduit closed at its faucet in a condition where the electrolyzed water is discharged only through said discharge conduit.
