- the reservoir 1 is provided with an outlet 5 for hypochlorous acid water 7 and an intake port 6 for introducing air into the reservoir 1 .
- the intake port 6 is arranged above the outlet 5 with a difference in height, thereby making it easier for air to enter from the intake port 6. - ⁇
- the size of the outlet 5 is designed to be as small as possible, and the opening of the intake port 6 is also made small by a filter or the like. As a result, small air bubbles enter the storage part 1 from the intake port 6, the vertical width of the water surface of the storage part 1 is reduced, and the generation of impact and kinetic energy is prevented, thereby suppressing the decomposition of hypochlorous acid.
- the intake port 6 is preferably provided at a position lower than the bottom surface 11 of the reservoir 1 and higher than the outlet 5 .
- a tank made of glass or resin can be used as the reservoir 1.
- Materials such as glass, PET resin, PMMA resin, ABS resin, ASA resin, and styrenic resin (GPPS, HIPS, etc.) are used for the members that make up the reservoir.
- PET resin, PMMA resin, ABS resin, styrenic resin (GPPS, HIPS, etc.) and the like are preferably used because they may accelerate the process and reduce the concentration of hypochlorous acid.
- the atomization mechanism 2 can be composed of, for example, an ultrasonic element 2a including an ultrasonic transducer and a diaphragm 2b.
- the diaphragm 2b is porous, and the lower surface is configured to contact the induction mechanism 3 described later, so that the hypochlorous acid water sucked up by the capillary phenomenon of the induction mechanism 3 reaches the diaphragm 2b. It's becoming
- the frequency range used is preferably high.
- the frequency range of the ultrasonic waves used is too high, the average particle size of the atomized hypochlorous acid water becomes smaller, and the hypochlorous acid tends to decompose easily. Therefore, the frequency region to be used can be appropriately selected in consideration of these tendencies.
- the frequency range to be used is not particularly limited, but is preferably 1.0 MHz or higher, more preferably 1.2 MHz or higher, and preferably 3.0 MHz or lower, more preferably 2.4 MHz or lower, and 1.6 MHz. More preferred are:

[5]前記霧化機構において使用する超音波の周波数領域が、1.0~3.0MHz、好ましくは1.0~2.4MHz、より好ましくは1.2~1.6MHzである上記[1]~[4]のいずれかに記載の次亜塩素酸水の噴霧装置
に関する。
実施の形態1による次亜塩素酸水7の噴霧装置100は、図1に示されるように、次亜塩素酸水7を貯留する貯留部1と、超音波振動を用いて次亜塩素酸水7を霧化する霧化機構2と、貯留部1から霧化機構2へ次亜塩素酸水7を毛細管現象により誘導する誘導機構3を備える。また、必要に応じて、霧化した霧状の次亜塩素酸水7を噴霧する噴霧機構4を備えてもよい。次亜塩素酸水7は、貯留部1から出口5を通って誘導機構3が配置される領域に供給され、誘導機構3の毛細管現象により霧化機構2の上、つまり振動板2b上に誘導される。これにより、振動素子2aや振動板2b上に滞留する次亜塩素酸水の量を減らすことができ、霧化機構2による次亜塩素酸への直接的な影響を抑制する構造となっている。
実施の形態2による次亜塩素酸水7の噴霧装置100は、上昇気流を発生させることにより、霧化された霧状の次亜塩素酸水を上方に噴霧する気流発生機構をさらに備えたものである。図2に示すように、噴き出し口8が、上昇気流(図中、矢印)を生成するためのファン9を備えた外周部10に覆われている構成となっている。つまり、図2においては、ファン9および外周部10により、霧化された霧状の次亜塩素酸水を上方に噴霧する気流発生機構が構成されている。ここで気流を生成するための手段はファンに限定されるものではないが、ガイドとなる外周部10と合わせて、生成された上昇気流により間接的に霧化された霧状の次亜塩素酸水を上方に噴霧できるような構成とすることが意図される。超音波による霧化機構2により霧化した霧状の次亜塩素酸水7は、通常ファン9を用いて噴き出し口8より外部へと噴出されるが、ファン9の風が霧状の次亜塩素酸水に直接当たることにより霧状の次亜塩素酸水中の次亜塩素酸が失活し、噴出した霧中の有効塩素濃度が低下する可能性がある。これに対し、図2に示すように外部に上昇気流を発生させて霧化した霧状の次亜塩素酸水の噴出を促すことにより、霧状の次亜塩素酸水は上方に効率よく噴出され、かつ直接ファンの風を当てた場合と比較して、次亜塩素酸の失活が良好に改善される。なお、図2において図1と同じ部分には図1と同じ符号を付してその説明は省略する。
