Abstract
Description
オゾン水は上記の如く優れた殺菌効果を有するものであるが、従来の電気化学的製造装置によって製造したオゾン水の場合にあっては、電解時において発生する粒径の大きなオゾンガスの気泡が多量に含まれている。そして、このオゾンガスは異臭が強いため、手足の殺菌等に用いるときにおいて気泡が破裂すると強い不快感を覚えることになる。
また、従来の電気化学的製造装置、特に有底円筒形の縦型電解槽ケース内に、板状陽極給電バーと板状陰極給電バーを平行して立設し、これらの間に、夫々が板状をなし、同一位置に所要径の貫通孔を穿設した、陽イオン交換膜を挟んで陽極電極と陰極電極を積層してなる電極アッセンブリを、上下方向に所定の間隔をおいて平行して配設した電気化学的製造装置の場合には、上下に位置する電極アッセンブリの全てが水平である。
このため上位と下位の電極アッセンブリ間において水の淀みが生じ易く、下位側の電極アッセンブリにより発生したオゾンガスの気泡が上位側の電極アッセンブリとの間に溜まってジュール熱の放散を妨げることになる。そして、これに伴い温度が40~50℃以上の高温になると電極アッセンブリの周辺の樹脂部品が変形してしまうこともある。そしてまた、この事態を避けるためにポンプを常に稼動させて水の流れを良くし、ジュール熱の放散を促進しなければならず、このために相当な電力を必要とする。

次に、上記実施形態の作用について説明する。
先ず、電解槽1における水の電気分解について説明すると、キャップ5の貫挿孔5aから突出する板状陽極給電バー7と板状陰極給電バー8の夫々を導線Lを介して電源(図示せず。)に接続して給電する。これにより電解槽1中に原水流入口3から流入した原水は、各電極アッセンブリ9、9、9により電気分解される。そして、その際に発生するオゾンガスの気泡を含んだ水は、全ての電極アッセンブリ9、9、9が上下方向において所定の角度に統一して傾斜していることから、各電極アッセンブリ9、9、9間を淀むことなくスムーズに通過する。したがって、各電極アッセンブリ9、9、9の間にオゾンガスの気泡が溜まることがない。そして、その後オゾン水流出口4から流出し、パイプ(図示せず。)を介してミキサー23に送出される。
電解槽1から送出されたオゾンガスの気泡を含んだ水は、ミキシングケース底部24のオゾン水流入口25から流入するが、このとき該オゾン水流入口25はミキシングケース底部24の下部側面における中心線を外れた位置に設けていることから、該ミキシングケース底部24の内壁に沿った円周方向の流れとなって上昇する。そして、下位に位置する渦流発生板30の通水孔30a、30aを経てこれの上部に位置する円筒形混合カラー32内に流入する。このとき、該渦流発生板30の通水孔30a、30aは、板厚方向に対して斜めで且つ円周方向に沿っていることから、円筒形混合カラー32内において水流が渦流となる。そして、渦流発生板30の通水孔30a、30aは、その傾きがミキシングケース底部24の内壁に沿った円周方向の水流に沿っていることと、流出側を窄めていることにより、該通水孔30a、30aから流出する際の流速が高められる。これにより、円筒形混合カラー32内の水は激しい渦流となり、水中に含まれるオゾンガスの気泡はこの渦流によってせん断され、微細化されるものである。そして、更に上位に位置する渦流発生板31により再度同様にオゾンガスの気泡のせん断が行われ、その後ミキシングケース本体27のオゾン水流出口28から流出するものである。
