PROBLEM TO BE SOLVED: To provide an electrolytic oxygen micro-nano bubble water generator having a physiological activity effect.SOLUTION: In the electrolytic oxygen micro-nano bubble water generator, a booster tank X including a pipe 24 for discharging excessive gas bubbles which float as a gas pool and stored water and further for retaining the surface level of the stored water, which is installed at the center, and a pair of electrodes with reversible positive and negative polarities for applying low-voltage direct current, which is installed on the bottom, is connected to a main tank Y longitudinally. In the booster tank, electrolytic oxygen micro-nano bubble water is generated by electrolysis of city water and supplied to the main tank, and in the main tank, the electrolytic oxygen micro-nano bubbles is increased by re-electrolysis. A donut-like peripheral residual portion is provided on the upper surface of a water purifying filter 15 constituted by activated carbon and a filtering material which are stored in the main tank or including molded fine powder activated carbon to form a recessed portion 27, and purified electrolytic oxygen micro-nano bubble water is discharged to the outside through a pipe communicating the recessed portion with a body bottom cylinder 22.COPYRIGHT: (C)2012,JPO&INPIT【課題】生理活性効果を持つ電解酸素マイクロナノバブル水生成器を提供する。【解決手段】電解酸素マイクロナノバブル水生成器は、浮上してガス溜まりとなる余分なガス気泡と、貯水の排出と、さらに貯水の液面レベルを保持するパイプ24を中央に、また、底部には陰、陽の極性を反転自在とした低電圧の直流を印加する対の電極をそれぞれに設置したブースタータンクXとメインタンクYを前後に連結し、ブースタータンクは水道水を電気分解して電解酸素マイクロナノバブル水を生成してメインタンクに給水し、メインタンクでは再度電気分解して電解酸素マイクロナノバブルを加増する。メインタンクに内蔵する活性炭およびろ過材で構成した、もしくは微粉活性炭を成形した浄水フィルター15の上面にドーナツ状の外周残部を設けて凹部27を形成、凹部と本体底円筒22を連通するパイプから浄水した電解酸素マイクロナノバブル水を外部に排出する。【選択図】図5
