PROBLEM TO BE SOLVED: To provide a washing device capable of reliably washing and sterilizing fingers, etc.SOLUTION: A washing device (M) includes a sink (41) which has an insertion port for putting in/taking out an object to be washed, can accommodate the object to be washed, and has an outlet for discharging used washing liquid, washing means (11, 12, 13, 14, etc.) for discharging the washing liquid in the sink, and air supply means (21, 22, 411, etc.) for supplying air into the sink. The washing means discharges, as washing liquid, diluted hypochlorous acid water of pH 4-6 made by mixing high-concentration hypochlorous acid water of pH 6-7 with dilution water. Thus, a degree of freedom can be increased for the adjustment of concentration, supply quantity, etc. of the washing liquid supplied to the object to be washed in washing. Also, washing utilizing hypochlorous acid excellent in a bactericidal effect most effectively is possible. Furthermore, by supplying ozone into the sink all the time, it is possible not only to sterilize fingers, but also to perform self-cleaning of the device and cleaning of the device installation space efficiently.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】手指等の洗浄および除菌を確実に行える洗浄装置を提供する。【解決手段】本発明の洗浄装置(M)は、洗浄対象を出し入れする挿入口を有し洗浄対象を収容できると共に使用した洗浄液を排出させる排出口を有するシンク(41)と、シンク内へ洗浄液を吐出する洗浄手段(11、12、13、14等)と、シンク内へ送気する送気手段(21、22、411等)とを備える。その洗浄手段は、pH6~7の高濃度次亜塩素酸水へ希釈水を混合したpH4~6の希釈次亜塩素酸水を洗浄液として吐出する。これにより、洗浄時に洗浄対象へ供給する洗浄液の濃度や供給量等の調整自由度を大きくできる。また、殺菌効果に優れる次亜塩素酸を最も有効に活用した洗浄が可能となる。さらに、シンク内へオゾンを常時供給することにより、手指の除菌のみならず、装置の自己浄化や装置の設置空間の清浄も効率的に行える。【選択図】図2
