PROBLEM TO BE SOLVED: To provide a simple means for achieving desired chloride ion concentration in water in an electrolysis unit of a system wherein hypochlorous acid is produced by electrolyzing water, provided that the desired chloride concentration is achieved when raw water supplied to the electrolysis unit has a low chloride ion concentration, by diffusing salt into the raw water so as to increase the chloride ion concentration in the raw water.SOLUTION: An electrolytic water generator includes: a cartridge 100 for sustained release of salt and the electrolysis unit 110 wherein electrolytic water 114 containing hypochlorous acid is produced by electrolyzing water. The cartridge 100 for sustained release of salt comprises: a cartridge body 102 filled with an aqueous solution of an inorganic salt chemically combined with Cl-, such as NaCl and a diffusion functional member 104 which is installed inside the cartridge body so that a tip thereof is exposed at a feed tip of the cartridge body, is infiltrated with the aqueous solution and diffuses chloride ions from the aqueous solution to the water in which the chloride ion concentration needs to be increased. The cartridge 100 has a sealable structure except the exposed tip part of the diffusion functional member 104 and is installed in the electrolysis unit so that the portion of the diffusion functional member exposed from the feed tip is immersed in the water in the electrolysis unit.COPYRIGHT: (C)2012,JPO&INPIT【課題】水を電気分解して次亜塩素酸を生成するシステムにおいて、塩化物イオン濃度が低い原水が電解部へ供給される状況の場合、その原水の塩化物イオン濃度を上昇させるために、食塩を原水に拡散させて電解部の水の塩化物イオン濃度が所期の値となる簡単な手段を提供する。【解決手段】カートリッジ本体部102内にNaCl等のCl-が化合した無機塩の水溶液が充填され、この水溶液が染み込みこの水溶液から塩化物イオンが塩化物イオン濃度を高めたい水に拡散する拡散機能部材104が、カートリッジ本体部の供給端部に露出するようにカートリッジ本体部内に配置され、供給端部の拡散機能部材部分を除いて密閉可能構造である塩徐放用カートリッジ100と、水の電気分解によって次亜塩素酸を含む電解水114を生成する電解部110を備え、供給端部から露出する拡散機能部材部分が電解部の水に浸るように、電解部に塩徐放用カートリッジを備える。【選択図】図1
