Abstract: An electrolyzed water-manufacturing apparatus comprises: a flow-through-type electrolysis tank, having a pair of electrodes disposed parallel to each other, obtained by forming an anode chamber and a cathode chamber with a diaphragm stretched between the electrodes parallel therewith, and through which water flows through the anode chamber and the cathode chamber sequentially; a electrolysis starting water supply tube connected to the inlet of the anode chamber for supplying electrolysis starting water only to the anode chamber; an electrolyzed water extraction tube connected to the outlet of the cathode chamber for extracting the electrolyzed water; a circulation tube connecting the anode chamber outlet to the cathode chamber inlet; a free chlorine-removing filter disposed in the circulation tube; and a circulation tube formed downstream of the free chlorine-removing filter.

Abstract: An electrolyzed water producing apparatus comprises an electrolysis unit including a diaphragm electrolytic cell and a diaphragmless electrolytic cell; a water supply pipe with a three-way valve; a water take-out pipe having one end connected to each anode chamber to remove anode electrolyzed water; a water take-out pipe having one end connected to each cathode chamber to remove cathode electrolyzed water; and a water take-out pipe provided with a free chlorine removing filter and having one end connected to each diaphragmless electrolytic chamber to remove mixed electrolyzed water. The diaphragm electrolytic cell contains a pair of electrode plates, and a plurality of electrolytic chambers, at least one of which includes an anode chamber and a cathode chamber. The diaphragmless electrolytic cell contains a pair of electrode plates, and diaphragmless electrolytic chambers which are the remaining electrolytic chambers.
