Electrolyzed water generation device

An electrolyzed water generation device comprising:

• an electrolytic chamber to which water to be electrolyzed is supplied;
• a first power feeder and a second power feeder disposed facing each other in the electrolytic chamber;
• and
• a membrane arranged between the first power feeder and the second power feeder and dividing the electrolytic chamber into a first polar chamber on a side of the first power feeder and a second polar chamber on a side of the second power feeder, characterized in that the electrolyzed water generation device further comprises:
• a first flow passage delivering electrolyzed water generated in one of the first polar chamber and the second polar chamber to a first water discharge port;
• a second flow passage delivering electrolyzed water generated in another one of the first polar chamber and the second polar chamber to a second water discharge port;
• a flow passage switching valve switching connections of the first polar chamber and the second polar chamber to the first flow passage and the second flow passage;
• a polarity switching unit switching polarities of the first power feeder and the second power feeder;
• a voltage detection unit detecting a voltage to be applied to the first power feeder and the second power feeder;
• a current detection unit detecting a current to be supplied to the first power feeder and the second power feeder;
• a storage unit storing a switching interval for the polarity switching unit and the flow passage switching valve;
• and
• a switching control unit switching the polarity and the flow passage switching valve based on the switching interval, wherein
• the switching control unit changes the switching interval stored in the storage unit based on a ratio of the voltage to the current.
