PROBLEM TO BE SOLVED: To supply an acid water and alkaline water with optimal particle size.SOLUTION: An ionized water supplying mechanism is provided with: an ionized water generator (60) which includes an electrode unit (62) having a water storage tank (61), an electrode pair (64, 65) and a power source (70) applying a voltage to the electrode pair (64, 65), and an ultrasonic generation part (104), and generates an acid water and alkaline water by electrolyzing the water in the storage tank (61) and a spray mechanism (90, 95) performing an acid water and alkaline water spray operations. The spray mechanism (90, 95) is composed so that the particle size of the alkaline water sprayed by the alkaline water spray operation is smaller than that of the acid water sprayed by the acid water spray operation. The electrode unit (62) forms a discharge field on the current pathway between the electrode pair (64, 65), and a hydroxide radical is generated by discharge. The ultrasonic generation part (104) converts hydrogen peroxide generated by change of the hydroxide radical into the hydroxide radical by ultrasonic irradiation into water.COPYRIGHT: (C)2013,JPO&INPIT【課題】酸性水やアルカリ水を最適な粒子径で供給する。【解決手段】イオン水供給機構に、貯水タンク(61)と電極対(64,65)及び該電極対(64,65)に電圧を印加する電源部(70)を有する電極ユニット部(62)と超音波発生部(104)とを含み、貯水タンク(61)内の水を電気分解して酸性水及びアルカリ水を生成するイオン水生成器(60)と、酸性水噴霧動作とアルカリ水噴霧動作とを行う噴霧機構(90,95)とを設ける。噴霧機構(90,95)は、酸性水噴霧動作により噴霧される酸性水の粒子径よりもアルカリ水噴霧動作により噴霧されるアルカリ水の粒子径を小さくするように構成され、電極ユニット部(62)は、電極対(64,65)間の電流経路に放電場を形成し、放電によって水酸ラジカルを生成し、超音波発生部(104)は、水中への超音波照射により、水酸ラジカルが変化して生成される過酸化水素を水酸ラジカルに変換する。【選択図】図1
