Electrolyzed water generation device and production device for water for dialysate preparation and method for electrolyzed water generation that use same

Abstract

An electrolyzed water generation device 1 comprising a plurality of electrolysis chambers 30, 40, ... for the electrolysis of water. Each electrolysis chamber 30, 40, ... has arranged therein: a firstpower feeder 31, 41, ... and a second power feeder 32, 42, ... arranged facing each other; and a partition membrane 33, 43, ... that divides the electrolysis chamber 30, 40,... into a first polar chamber 30A, 40A on the first power feeder 31, 41 ... side and a second polar chamber 30B, 40B, ... on the second power feeder 32, 42, ... side. A solid polymer membrane is used as the partition membrane33, 43, .... At least two electrolysis chambers 30, 40 are connected by parallel water channels 51 that connect the first polar chambers 30A, 40A in parallel and by a serial water channel 55 that connects the second polar chambers 30B, 40B in series.

Description

technical field [0001] The present invention relates to an electrolyzed water generating device and the like which electrolyze water to generate electrolyzed water. Background technique [0002] Conventionally, there is known an electrolyzed water generator that includes an electrolyzer having electrolyzed chambers partitioned by a diaphragm, and electrolyzes tap water or the like supplied to the electrolyzed chamber to generate electrolyzed hydrogen water in which hydrogen is dissolved. For example, Patent Document 1 discloses an electrolyzed water generator including two electrolytic cells connected in series in order to increase the dissolved hydrogen concentration. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent No. 4417707 [0006] In the electrolyzed water generating device described above, the electrolyzed hydrogen water is generated in the cathode chamber in which the cathode power supply is disposed. At this ti...

Problems solved by technology

Also, in this case, since the water flow in the anode chamber is suppressed, it is difficult for the oxygen in the bubble state to be discharged from the anode chamber together with the electrolyzed water, so that the oxygen in the bubble state stays in the anode chamber

When the oxygen gas in this bubble state stays attached to the surface of the anode power supply body, etc., the water supplied to the surface of the power supply body decreases, so electrolysis in th
