　［概要］
　まず、図１を参照して、実施の形態１に係る静電霧化装置の概要について説明する。 (Embodiment 1)
[Overview]

As shown in FIG. 1, the electrostatic atomizer 100 according to Embodiment 1 includes a first solution tank 10, an ejection plate 20, a counter electrode 30, a first voltage application unit 40, and a second voltage application. The unit 41 includes a first electrode 110, a second electrode 120, and a controller 70. The ejection plate 20 includes an electrode support plate 21 and a plurality of nozzles 26.
　なお、図１では、コントローラ７０を機能的なブロックとして表している。コントローラ７０は、例えばマイコン（マイクロコントローラ）等で実現され、静電霧化装置１００の外殻筐体（図示せず）の内部に配置されている。コントローラ７０は、例えば、第１溶液槽１０の外側に取り付けられていてもよい。 In FIG. 1, the controller 70 is represented as a functional block. The controller 70 is realized by, for example, a microcomputer (microcontroller) or the like, and is disposed inside an outer casing (not shown) of the electrostatic atomizer 100. For example, the controller 70 may be attached to the outside of the first solution tank 10.
　静電霧化装置１００は、溶液２００を霧化して噴出する噴霧装置である。具体的には、静電霧化装置１００は、溶液２００に電圧を印加して殺菌効果を有する電解水（言い換えると、機能水）を生成し、生成した電解水に高電圧を印加して静電気力を発生させ、発生させた静電気力によって溶液２００を微細化し霧化させる。静電霧化装置１００は、例えば、殺菌装置又は除菌装置等に利用される。 The electrostatic atomizer 100 is a spray device that atomizes the solution 200 and ejects it. Specifically, the electrostatic atomizer 100 generates electrolyzed water having a bactericidal effect by applying a voltage to the solution 200 (in other words, functional water), and applies a high voltage to the generated electrolyzed water to generate static electricity. A force is generated, and the solution 200 is atomized and atomized by the generated electrostatic force. The electrostatic atomizer 100 is used for a sterilizer or a sterilizer, for example.
　静電霧化装置１００は、図示しないポンプ等により第１溶液槽１０内に収容された溶液２００を複数のノズル２６の各々の先端へ導き、先端に設けられた開口２７から溶液２００を霧状にしたミストＭを噴出する。具体的には、第１電圧印加部４０が第１電極１１０と対向電極３０との間に高電圧を印加することで、複数のノズル２６の開口２７から、霧状の溶液２００を噴出する。ここで、高電圧とは、例えば、図１に示すグランド電位（０Ｖ）を基準とした場合に、５ｋＶ程度であるが、特に限定されない。なお、対向電極３０の電圧は、グランド電位に対して、正であってもよいし、負であってもよい。 The electrostatic atomizer 100 guides the solution 200 accommodated in the first solution tank 10 to each tip of the plurality of nozzles 26 by a pump or the like (not shown), and the solution 200 is atomized from the opening 27 provided at the tip. The mist M made is ejected. Specifically, when the first voltage application unit 40 applies a high voltage between the first electrode 110 and the counter electrode 30, the mist-like solution 200 is ejected from the openings 27 of the plurality of nozzles 26. Here, the high voltage is, for example, about 5 kV when the ground potential (0 V) shown in FIG. 1 is used as a reference, but is not particularly limited. Note that the voltage of the counter electrode 30 may be positive or negative with respect to the ground potential.
　ノズル２６の内部には、第１溶液槽１０内の溶液２００を開口２７へ導くが形成されており、当該流路を通って開口２７から出た溶液２００は、電界によって形状が変化し、テーラーコーンを形成する。テーラーコーンの先端で溶液２００が微細化されることで、ミストＭが生成される。 Inside the nozzle 26 is formed a guide for the solution 200 in the first solution tank 10 to the opening 27. The shape of the solution 200 that has passed through the flow path from the opening 27 is changed by an electric field, and is tailored. Form a cone. The mist M is produced | generated when the solution 200 is refined | miniaturized by the front-end | tip of a tailor cone.
　なお、図１には、ノズル２６を４つ図示しているが、噴出板２０に形成されるノズルの数は、特に限定されず、３以下であってもよいし、５以上であってもよい。 In FIG. 1, four nozzles 26 are illustrated, but the number of nozzles formed on the ejection plate 20 is not particularly limited, and may be 3 or less, or 5 or more. Good.
　複数のノズル２６の各々の先端で生成されたミストＭは、対向電極３０に向けて放出される。ミストＭを対向電極３０の前方に放出させるために、対向電極３０の平板部３１には、ノズル２６の正面に対応する位置に、貫通孔３２が設けられている。これにより、ミストＭは、貫通孔３２を介して対向電極３０の前方に放出される。なお、「前方」とは、ミストＭが放出される方向であって、対向電極３０を基準としてノズル２６とは反対側の方向である。 The mist M generated at the tip of each of the plurality of nozzles 26 is discharged toward the counter electrode 30. In order to discharge the mist M to the front of the counter electrode 30, the flat plate portion 31 of the counter electrode 30 is provided with a through hole 32 at a position corresponding to the front surface of the nozzle 26. Thereby, the mist M is discharged to the front of the counter electrode 30 through the through hole 32. The “front” is a direction in which the mist M is emitted and is a direction opposite to the nozzle 26 with respect to the counter electrode 30.
　なお、本明細書においては、第１溶液槽１０に収容されており、第１電極１１０及び第２電極１２０によって電気分解される前の溶液、及び、電気分解された後の溶液を総称して、溶液２００と呼称する場合がある。 In the present specification, the solution stored in the first solution tank 10 and before being electrolyzed by the first electrode 110 and the second electrode 120 and the solution after being electrolyzed are collectively referred to. , Sometimes referred to as solution 200.

The nozzle 26 may have a height ratio to the outer diameter (hereinafter referred to as an aspect ratio) of 4 or more. Here, the height of the nozzle 26 is represented by the distance from the tip of the nozzle 26 to the main surface 22. The height is, for example, 2 mm or more. As the aspect ratio of the nozzle 26 increases, the electric field tends to concentrate on the tip of the nozzle 26. For this reason, the aspect ratio of the nozzle 26 may be 6 or more, for example. According to the study by the present inventors, it was confirmed that when the aspect ratio is 4 or more, the shape of the tailor cone is stabilized and the spray amount of the mist M is stabilized.

Although the opening diameter of the through-hole 32 is not specifically limited, For example, it is the range of 1 mm or more and 2.25 mm or less.

A voltage is applied between the nozzle 26 that discharges to the outside of the tank 10 and the nozzle 26 outside the first solution tank 10, and the electrolyzed solution is applied to the first electrode 110. A counter electrode 30 which is discharged from the nozzle 26 and atomized.
　従来、溶液を電気分解して電解水を生成し、生成した電解水を霧状にして噴出する装置では、溶液を電気分解して電解水を生成する電極対と、電解水を霧状にして噴出する電極対とがそれぞれ別に設けられていた。 Conventionally, in an apparatus that electrolyzes a solution to generate electrolyzed water, and sprays the generated electrolyzed water in the form of a mist, an electrode pair that electrolyzes the solution to generate electrolyzed water and the electrolyzed water in the form of a mist A pair of electrodes to be ejected was provided separately.
　しかしながら、静電霧化装置１００は、溶液２００を電気分解して電解水を生成する電極対の一方と、電解水を霧状にして噴出する電極対の一方とが、共通化されている。具体的には、静電霧化装置１００が有する第１電極１１０は、第２電極１２０との間に電圧が印加されることで溶液２００の電気分解を行い、対向電極３０との間に電圧が印加されることで電気分解された溶液２００の霧化とを行う。 However, in the electrostatic atomizer 100, one of the electrode pair that electrolyzes the solution 200 to generate electrolyzed water and one of the electrode pair that ejects the electrolyzed water in a mist form are shared. Specifically, the first electrode 110 included in the electrostatic atomizer 100 electrolyzes the solution 200 by applying a voltage between the second electrode 120 and the voltage between the first electrode 110 and the counter electrode 30. Is applied to atomize the electrolyzed solution 200.
　そのため、このような構成によれば、従来の構成と比較して、電極の数を減らすことができる。つまり、このような構成によれば、静電霧化装置１００は、簡便な構造で、殺菌、脱臭等の効果の高い霧状の液体（ミストＭ）を噴霧することができる。 Therefore, according to such a configuration, the number of electrodes can be reduced as compared with the conventional configuration. That is, according to such a configuration, the electrostatic atomizer 100 can spray a mist-like liquid (mist M) having a simple structure and high effects such as sterilization and deodorization.
　例えば、第１溶液槽１０に収容される溶液２００に含まれる電解質は、塩素イオンを含む。 For example, the electrolyte contained in the solution 200 accommodated in the first solution tank 10 contains chlorine ions.
　このような構成によれば、殺菌効果の高い次亜塩素酸を生成することができる。つまり、このような構成によれば、静電霧化装置１００は、殺菌効果の高い電解水を生成することができるため、殺菌効果の高いミストＭを噴霧させることができる。 According to such a configuration, hypochlorous acid having a high bactericidal effect can be generated. That is, according to such a structure, since the electrostatic atomizer 100 can produce | generate electrolyzed water with a high bactericidal effect, it can spray the mist M with a high bactericidal effect.
　（実施の形態２）
　続いて、図２を参照して、実施の形態２に係る電解水生成装置について説明する。 (Embodiment 2)
Then, with reference to FIG. 2, the electrolyzed water generating apparatus which concerns on Embodiment 2 is demonstrated.
　実施の形態２に係る静電霧化装置は、実施の形態１に係る静電霧化装置１００の構成に、さらに、溶液２００内のイオンの移動を制限する隔膜であるイオン透過膜を備える。 The electrostatic atomizer according to the second embodiment further includes an ion permeable membrane that is a diaphragm that restricts the movement of ions in the solution 200 in addition to the configuration of the electrostatic atomizer 100 according to the first embodiment.
　なお、実施の形態２に係る静電霧化装置の説明においては、実施の形態１に係る静電霧化装置１００と実質的に同一の構成に関しては同一の符号を付しており、重複する説明は省略又は簡略化される場合がある。 In addition, in description of the electrostatic atomizer which concerns on Embodiment 2, the same code | symbol is attached | subjected about the structure substantially the same as the electrostatic atomizer 100 which concerns on Embodiment 1, and it overlaps. The description may be omitted or simplified.
　図２は、実施の形態２に係る静電霧化装置１０１の構成を示す図である。 FIG. 2 is a diagram illustrating a configuration of the electrostatic atomizer 101 according to the second embodiment.
　図２に示すように、実施の形態２に係る静電霧化装置１０１は、実施の形態１に係る静電霧化装置１００と同様に、第１溶液槽１０と、噴出板２０と、対向電極３０と、第１電圧印加部４０と、第２電圧印加部４１と、第１電極１１０と、第２電極１２０と、コントローラ７０とを有する。また、静電霧化装置１０１は、さらに、イオン透過膜１４０を有する。 As shown in FIG. 2, the electrostatic atomizer 101 according to the second embodiment is opposite to the first solution tank 10, the ejection plate 20, and the electrostatic atomizer 100 according to the first embodiment. The electrode 30, the first voltage application unit 40, the second voltage application unit 41, the first electrode 110, the second electrode 120, and the controller 70 are included. The electrostatic atomizer 101 further includes an ion permeable film 140.
　イオン透過膜１４０は、第１溶液槽１０内の溶液２００に含まれるイオンの移動を制限する部材である。イオン透過膜１４０は、例えば、多孔質膜又はイオン交換膜である。多孔質膜の材料は、例えば、セラミック材料、樹脂材料が採用されるが、特に限定されない。また、イオン交換膜としては、例えば、陽イオン交換膜又は陰イオン交換膜が採用されてもよいし、両イオン交換膜が採用されてもよい。 The ion permeable membrane 140 is a member that restricts the movement of ions contained in the solution 200 in the first solution tank 10. The ion permeable membrane 140 is, for example, a porous membrane or an ion exchange membrane. As the material of the porous membrane, for example, a ceramic material or a resin material is adopted, but is not particularly limited. Moreover, as an ion exchange membrane, a cation exchange membrane or an anion exchange membrane may be employ | adopted, for example, and both ion exchange membranes may be employ | adopted.
　イオン透過膜１４０は、第１溶液槽１０内で、第１電極１１０と第２電極１２０との間に配置される。言い換えると、第１電極１１０は、イオン透過膜１４０によって仕切られた第１溶液槽１０の一方側である第１室１０ａに配置され、第２電極１２０は、第１電極１１０とは反対側の他方側である第２室１０ｂに配置される。また、イオン透過膜１４０は、第１溶液槽１０内を、ノズル２６と内部が繋がっており、溶液２００が直接移動可能な側である第１室１０ａと、ノズル２６と内部が繋がっておらず、溶液２００が直接移動不可能な側である第２室１０ｂとに仕切っている。第１電極１１０は、イオン透過膜１４０によって仕切られた第１溶液槽１０内のノズル２６側である第１室１０ａに配置されている。 The ion permeable membrane 140 is disposed between the first electrode 110 and the second electrode 120 in the first solution tank 10. In other words, the first electrode 110 is disposed in the first chamber 10 a that is one side of the first solution tank 10 partitioned by the ion permeable membrane 140, and the second electrode 120 is on the opposite side of the first electrode 110. It arrange | positions at the 2nd chamber 10b which is the other side. The ion permeable membrane 140 is connected to the inside of the first solution tank 10 with the nozzle 26, and is not connected to the inside of the first chamber 10 a on the side where the solution 200 can directly move and the nozzle 26. The solution 200 is partitioned from the second chamber 10b, which is the side that cannot directly move. The first electrode 110 is disposed in the first chamber 10 a on the nozzle 26 side in the first solution tank 10 partitioned by the ion permeable membrane 140.
　電解水は、第１電極１１０及び第２電極１２０の間に電圧が印加されて溶液２００が電気分解されることで、生成される。より具体的には、例えば、溶液２００が塩素イオンを含む水であり、且つ、第１電極１１０を陽極電極とし、第２電極を陰極とするように、第２電圧印加部４１によって第１電極１１０及び第２電極１２０に電位が印加された場合、第１電極１１０側に、次亜塩素酸等の高い殺菌効果を有する物質を含む酸性の電解水が生成され、第２電極１２０側に、アルカリ性の電解水が生成される。このような配置とすることで、第１電極１１０側に生成される殺菌効果の高い次亜塩素酸等の塩素系物質を含む酸性の電解水は、ミストＭとして第１溶液槽１０内から噴出され易くなる。 Electrolyzed water is generated by applying a voltage between the first electrode 110 and the second electrode 120 to electrolyze the solution 200. More specifically, for example, the first voltage is applied by the second voltage application unit 41 so that the solution 200 is water containing chlorine ions, the first electrode 110 is an anode electrode, and the second electrode is a cathode. When an electric potential is applied to 110 and the second electrode 120, acidic electrolyzed water containing a substance having a high bactericidal effect such as hypochlorous acid is generated on the first electrode 110 side, and on the second electrode 120 side, Alkaline electrolyzed water is generated. With this arrangement, acidic electrolyzed water containing a chlorine-based substance such as hypochlorous acid having a high bactericidal effect generated on the first electrode 110 side is ejected from the first solution tank 10 as mist M. It becomes easy to be done.
　［効果等］
　以上のように、実施の形態２に係る静電霧化装置１０１は、実施の形態１に係る静電霧化装置１００の構成要素に加えて、さらに、第１電極１１０と第２電極１２０との間に配置されるイオン透過膜１４０を有する。 [Effects]
As described above, in addition to the components of the electrostatic atomizer 100 according to the first embodiment, the electrostatic atomizer 101 according to the second embodiment further includes the first electrode 110 and the second electrode 120. The ion permeable membrane 140 is disposed between the two.
　このような構成によれば、実施の形態１に係る静電霧化装置１００の効果に加えて、さらに、第１電極１１０側に生成される電解水（実施の形態２においては、酸性の電解水）と、第２電極１２０側に生成される電解水（実施の形態２においては、アルカリ性の電解水）とを分離して混ざりにくくすることができる効果を得ることができる。そのため、例えば、溶液２００に塩化ナトリウムが添加されている場合、ナトリウムイオンが陽極となっている第１電極１１０側へ移動しにくくなり、第１電極１１０側に生成された電解水にナトリウムイオンが混ざりにくくなるため、当該電解水がミストＭとなって噴出される際に、ミストＭにナトリウムイオンが混ざりこんで、ナトリウムイオンが第１溶液槽１０の外部に取り出されることを抑制できる。また、このような構成によれば、陽極となっている第１電極１１０側に生成される電解水の殺菌効果の低下を抑制することができる。 According to such a configuration, in addition to the effect of the electrostatic atomizer 100 according to the first embodiment, the electrolyzed water generated on the first electrode 110 side (in the second embodiment, acidic electrolysis) Water) and electrolyzed water produced on the second electrode 120 side (alkaline electrolyzed water in the second embodiment) can be separated and made difficult to mix. Therefore, for example, when sodium chloride is added to the solution 200, it becomes difficult for sodium ions to move to the first electrode 110 side serving as an anode, and sodium ions are generated in the electrolyzed water generated on the first electrode 110 side. Since it becomes difficult to mix, when the electrolyzed water is ejected as mist M, it is possible to prevent sodium ions from mixing into the mist M and taking out sodium ions to the outside of the first solution tank 10. Moreover, according to such a structure, the fall of the bactericidal effect of the electrolyzed water produced | generated on the 1st electrode 110 side used as an anode can be suppressed.
　例えば、イオン透過膜１４０は、ノズル２６と繋がる第１室１０ａと、ノズル２６と繋がらない第２室１０ｂとに第１溶液槽１０の内部を仕切る。この場合、第１電極１１０は、第１室１０ａに配置され、第２電極１２０は、第２室１０ｂに配置されるとよい。 For example, the ion permeable membrane 140 partitions the inside of the first solution tank 10 into a first chamber 10 a connected to the nozzle 26 and a second chamber 10 b not connected to the nozzle 26. In this case, the first electrode 110 may be disposed in the first chamber 10a, and the second electrode 120 may be disposed in the second chamber 10b.
　このような構成によれば、第２室１０ｂに第１電極１１０が配置される場合と比較して、第１電極１１０と対向電極３０との距離が近くなる。そのためノズル２６から放出される電気分解された溶液２００に電圧が印加されやすくなるため、当該溶液２００が霧化されやすくなる。 According to such a configuration, the distance between the first electrode 110 and the counter electrode 30 is shorter than when the first electrode 110 is disposed in the second chamber 10b. Therefore, since a voltage is easily applied to the electrolyzed solution 200 discharged from the nozzle 26, the solution 200 is easily atomized.
　（実施の形態２の変形例１）
　上記実施の形態２においては、静電霧化装置１０１は、１つのイオン透過膜１４０を備える。しかしながら、静電霧化装置は、例えば、２つのイオン透過膜を備えてもよい。 (Modification 1 of Embodiment 2)
In the second embodiment, the electrostatic atomizer 101 includes one ion permeable membrane 140. However, the electrostatic atomizer may include, for example, two ion permeable membranes.
　図３は、実施の形態２の変形例１に係る静電霧化装置１０１ａの構成を示す図である。 FIG. 3 is a diagram illustrating a configuration of an electrostatic atomizer 101a according to the first modification of the second embodiment.
　図３に示すように、静電霧化装置１０１ａは、２つのイオン透過膜１４０ａ、１４０ｂを備える。２つのイオン透過膜１４０ａ、１４０ｂは、いずれも筐体１０内で第１電極１１０及び第２電極１２０の間に配置される。また、第１溶液槽１０の内部には、第１電極１１０及び第２電極１２０が配置されない溶液２００が収容される空間である第３室１０ｃが形成される。静電霧化装置１０１ａが電気分解を実行する前には、第１溶液槽１０内において、第３室１０ｃに塩化ナトリウム等の塩素イオン等の電解質を含む溶液が収容され、第１電極１１０が配置される空間である第１室１０ａ及び第２電極１２０が配置される空間である第２室１０ｂには水が収容される。 As shown in FIG. 3, the electrostatic atomizer 101a includes two ion permeable membranes 140a and 140b. The two ion permeable membranes 140 a and 140 b are both disposed between the first electrode 110 and the second electrode 120 in the housing 10. In addition, a third chamber 10c that is a space for storing the solution 200 in which the first electrode 110 and the second electrode 120 are not disposed is formed in the first solution tank 10. Before the electrostatic atomizer 101a performs electrolysis, a solution containing an electrolyte such as chlorine ion such as sodium chloride is accommodated in the third chamber 10c in the first solution tank 10, and the first electrode 110 is Water is accommodated in the first chamber 10a, which is a space where the second electrode 120 is disposed, and the second chamber 10b, which is a space where the second electrode 120 is disposed.
　例えば、２つのイオン透過膜１４０ａ、１４０ｂのうち、陽極となる第１電極１１０側に配置される側のイオン透過膜１４０ａには、陰イオン透過膜が採用され、陰極となる第２電極１２０側に配置される側のイオン透過膜１４０ｂには、陽イオン透過膜が採用される。 For example, of the two ion permeable membranes 140a and 140b, an anion permeable membrane is employed for the ion permeable membrane 140a on the side disposed on the first electrode 110 side serving as the anode, and the second electrode 120 side serving as the cathode. A cation permeable membrane is adopted as the ion permeable membrane 140b on the side disposed on the surface.
　このような構成によれば、第１電極１１０側に生成された電解水にナトリウムイオンがより混ざりにくくなる。もちろん、２つのイオン透過膜１４０ａ、１４０ｂには、それぞれ両イオン交換膜が採用されてもよいし、一方に両イオン交換膜が採用され、他方に陽イオン透過膜又は陰イオン透過膜が採用される等、適宜変更がなされてよい。 According to such a configuration, sodium ions are less likely to be mixed with the electrolyzed water generated on the first electrode 110 side. Of course, both ion exchange membranes may be adopted for the two ion permeable membranes 140a and 140b, respectively, both ion exchange membranes are adopted on one side, and cation permeable membranes or anion permeable membranes are adopted on the other side. Changes may be made as appropriate.
　（実施の形態２の変形例２）
　上記実施の形態２においては、第２電極１２０がグランド電極となるように設計されていたが、グランド電極となる電極は、第１電極１１０でもよい。 (Modification 2 of Embodiment 2)
In the second embodiment, the second electrode 120 is designed to be a ground electrode. However, the electrode to be the ground electrode may be the first electrode 110.
　図４は、実施の形態２の変形例２に係る静電霧化装置１０２の構成を示す図である。 FIG. 4 is a diagram illustrating a configuration of the electrostatic atomizer 102 according to the second modification of the second embodiment.
　図４に示すように、実施の形態２の変形例２に係る静電霧化装置１０２は、実施の形態２に係る静電霧化装置１０１と同様の構成要素を有する。ここで、実施の形態２の変形例２に係る静電霧化装置１０２は、実施の形態２に係る静電霧化装置１０１と、接地される電極が異なる。具体的には、静電霧化装置１０２が有する第２電極１２０が、グランド電極となっている。この場合、例えば、対向電極３０には、第２電極１２０から見て＋５ｋＶ又は－５ｋＶ程度の電位が第１電圧印加部４０によって印加される。また、第１電極１１０には、第２電極１２０から見て＋５Ｖ又は－５Ｖ程度の電位が第２電圧印加部４１によって印加される。このような構成によってもまた、実施の形態２の変形例２に係る静電霧化装置１０２は、実施の形態２に係る静電霧化装置１０１と同様の効果を奏する。 As shown in FIG. 4, the electrostatic atomizer 102 according to the second modification of the second embodiment has the same components as the electrostatic atomizer 101 according to the second embodiment. Here, the electrostatic atomizer 102 according to the second modification of the second embodiment is different from the electrostatic atomizer 101 according to the second embodiment in the grounded electrode. Specifically, the 2nd electrode 120 which the electrostatic atomizer 102 has is a ground electrode. In this case, for example, a potential of about +5 kV or −5 kV as viewed from the second electrode 120 is applied to the counter electrode 30 by the first voltage application unit 40. In addition, a potential of about +5 V or −5 V as viewed from the second electrode 120 is applied to the first electrode 110 by the second voltage application unit 41. Also with such a configuration, the electrostatic atomizer 102 according to the second modification of the second embodiment has the same effects as the electrostatic atomizer 101 according to the second embodiment.

　なお、実施の形態３に係る静電霧化装置の説明においては、実施の形態１に係る静電霧化装置１００と実質的に同一の構成に関しては同一の符号を付しており、重複する説明は省略又は簡略化される場合がある。 In addition, in description of the electrostatic atomizer which concerns on Embodiment 3, about the structure substantially the same as the electrostatic atomizer 100 which concerns on Embodiment 1, the same code | symbol is attached | subjected and it overlaps. The description may be omitted or simplified.

　図５に示すように、実施の形態３に係る静電霧化装置１０３は、実施の形態１に係る静電霧化装置１００と同様に、第１溶液槽１０と、噴出板２０と、対向電極３０と、第１電圧印加部４０と、第２電圧印加部４１と、第１電極１１０と、第２電極１２０と、コントローラ７０とを有する。また、静電霧化装置１０３は、さらに、第２溶液槽１１と、循環部８０とを有する。 As shown in FIG. 5, the electrostatic atomizer 103 according to the third embodiment is opposite to the first solution tank 10, the ejection plate 20, and the electrostatic atomizer 100 according to the first embodiment. The electrode 30, the first voltage application unit 40, the second voltage application unit 41, the first electrode 110, the second electrode 120, and the controller 70 are included. The electrostatic atomizer 103 further includes a second solution tank 11 and a circulation unit 80.
　第２溶液槽１１は、第１溶液槽１０と繋がり、少なくとも電解質を含む溶液２００を収容する。具体的には、第２溶液槽１１には、第１溶液槽１０に収容されている溶液２００と同様の溶液が収容されていればよい。そのため、第２溶液槽１１に収容されている溶液２００の含まれる電解質もまた、第１溶液槽１０に収容されている溶液２００に含まれる電解質と同様であればよい。当該電解質は、例えば、塩素イオンを含む。 The second solution tank 11 is connected to the first solution tank 10 and contains a solution 200 containing at least an electrolyte. Specifically, the second solution tank 11 only needs to store a solution similar to the solution 200 stored in the first solution tank 10. Therefore, the electrolyte contained in the solution 200 accommodated in the second solution tank 11 may be the same as the electrolyte contained in the solution 200 accommodated in the first solution tank 10. The electrolyte includes, for example, chlorine ions.
　第２溶液槽１１は、例えばステンレス等の金属材料を用いて形成されているが、樹脂材料を用いて形成されていてもよい。このとき、第２溶液槽１１は、耐酸性若しくは耐アルカリ性又はこれらの両方の性質を有する材料を用いて形成されていてもよい。 The second solution tank 11 is formed using, for example, a metal material such as stainless steel, but may be formed using a resin material. At this time, the second solution tank 11 may be formed using a material having acid resistance, alkali resistance, or both of these properties.
　第２溶液槽１１の形状は、例えば、上面が開放された円柱状であるが、これに限らない。第２溶液槽１１の形状は、立方体又は直方体状でもよく、扁平なトレイ状でもよい。第２溶液槽１１は、例えば、第２溶液槽１１の開放された上面が板体等によって覆われている。具体的には、第２溶液槽１１と当該板体とが組み合わされて、第２溶液槽１１内の溶液２００が漏れ出ないように密閉容器を形成している。また、当該板体には、例えば、配管６０、６１を差し込むための貫通孔が形成されている。 The shape of the second solution tank 11 is, for example, a cylindrical shape with an open upper surface, but is not limited thereto. The shape of the second solution tank 11 may be a cube or a rectangular parallelepiped, or may be a flat tray. As for the 2nd solution tank 11, the open upper surface of the 2nd solution tank 11 is covered with the plate etc., for example. Specifically, the second solution tank 11 and the plate body are combined to form a sealed container so that the solution 200 in the second solution tank 11 does not leak. Moreover, the through-hole for inserting piping 60, 61 is formed in the said plate, for example.
　循環部８０は、第１溶液槽１０内に収容されている溶液２００を第２溶液槽１１へ送液し、且つ、第２溶液槽１１内に収容されている溶液２００を、第１溶液槽１０へ送液するように、第１溶液槽１０内及び第２溶液槽１１内の溶液２００を循環させるための機構である。循環部８０は、例えば、ポンプ５０、５１と、配管６０、６１とを備える。 The circulation unit 80 sends the solution 200 accommodated in the first solution tank 10 to the second solution tank 11, and the solution 200 accommodated in the second solution tank 11 is transferred to the first solution tank 11. 10 is a mechanism for circulating the solution 200 in the first solution tank 10 and the second solution tank 11 so as to be fed to the liquid. The circulation unit 80 includes, for example, pumps 50 and 51 and pipes 60 and 61.
　ポンプ５０は、第１溶液槽１０内の溶液２００を、第２溶液槽１１に送液する送液装置である。ポンプ５０による第２溶液槽１１への溶液２００の供給量を調整することで、循環される液量が制御される。 The pump 50 is a liquid feeding device that feeds the solution 200 in the first solution tank 10 to the second solution tank 11. By adjusting the supply amount of the solution 200 to the second solution tank 11 by the pump 50, the amount of liquid to be circulated is controlled.
　配管６０は、溶液２００を第１溶液槽１０から第２溶液槽１１へ送液するために、第１溶液槽１０と第２溶液槽１１とを繋ぐ管である。図５では、配管６０の途中にポンプ５０が設けられている。 The pipe 60 is a pipe connecting the first solution tank 10 and the second solution tank 11 in order to send the solution 200 from the first solution tank 10 to the second solution tank 11. In FIG. 5, a pump 50 is provided in the middle of the pipe 60.
　配管６０は、例えば、ステンレス等の金属材料を用いて形成されている。配管６０は、溶液２００の性質に応じて、耐酸性若しくは耐アルカリ性又はこれらの両方の性質を有する材料を用いて形成されていてもよい。 The pipe 60 is formed using a metal material such as stainless steel, for example. The pipe 60 may be formed using a material having acid resistance or alkali resistance, or both of these characteristics, depending on the properties of the solution 200.

In FIG. 5, a pump 51 is provided in the middle of the pipe 61.
　配管６１は、例えば、ステンレス等の金属材料を用いて形成されている。配管６１は、溶液２００の性質に応じて、耐酸性若しくは耐アルカリ性又はこれらの両方の性質を有する材料を用いて形成されていてもよい。 The piping 61 is formed using metal materials, such as stainless steel, for example. The pipe 61 may be formed using a material having acid resistance or alkali resistance, or both of these characteristics depending on the properties of the solution 200.
　なお、循環部８０が有するポンプ５０、５１は、それぞれ独立して駆動できるように設計されていてもよいし、コントローラ７０によって制御されてもよい。例えば、コントローラ７０は、ポンプ５０、５１を制御することで、第１溶液槽１０及び第２溶液槽１１の間を循環する溶液２００の液量、流速、及び、タイミング等を制御する。この場合、コントローラ７０は、ポンプ５０、５１を制御することができればよく、無線信号を送信することでポンプ５０、５１を制御してもよいし、ポンプ５０、５１と制御線等により接続されていてもよい。 The pumps 50 and 51 included in the circulation unit 80 may be designed so that they can be driven independently, or may be controlled by the controller 70. For example, the controller 70 controls the pumps 50 and 51 to control the amount, flow rate, timing, and the like of the solution 200 that circulates between the first solution tank 10 and the second solution tank 11. In this case, the controller 70 only needs to be able to control the pumps 50 and 51, and may control the pumps 50 and 51 by transmitting radio signals, or is connected to the pumps 50 and 51 by a control line or the like. May be.
　また、例えば、ポンプ５０、５１は、それぞれ独立したポンプで構成されてもよいし、双方向に送液可能な１つのポンプ等の送液装置により構成されてもよい。この場合、配管は、第１溶液槽１０と第２溶液槽１１とを繋ぐ１つの配管によって構成されてもよい。 Further, for example, the pumps 50 and 51 may be constituted by independent pumps or may be constituted by a liquid feeding device such as one pump capable of feeding in both directions. In this case, the pipe may be configured by one pipe connecting the first solution tank 10 and the second solution tank 11.
　［効果等］
　以上のように、実施の形態３に係る静電霧化装置１０３は、実施の形態１に係る静電霧化装置１００の構成要素に加えて、さらに、第１溶液槽１０と繋がり、少なくとも電解質を含む溶液２００を収容する第２溶液槽１１と、第１溶液槽１０及び第２溶液槽１１に収容されている溶液２００を循環させる循環部８０と、を有する。 [Effects]
As described above, the electrostatic atomizer 103 according to Embodiment 3 is further connected to the first solution tank 10 in addition to the components of the electrostatic atomizer 100 according to Embodiment 1, and at least the electrolyte. A second solution tank 11 that contains a solution 200 containing, and a circulation unit 80 that circulates the solution 200 contained in the first solution tank 10 and the second solution tank 11.
　このような構成によれば、第１溶液槽１０内及び第２溶液槽１１内のそれぞれに収容されている溶液２００が、第１溶液槽１０内及び第２溶液槽１１内の一方から他方へ移動されるために、溶液２００を簡便に攪拌することができるため、ミストＭを生成するために悪影響を及ぼす溶液２００内の気泡等を取り除くことができる。また、電気分解によって次亜塩素酸等の殺菌効果を有する塩素系物質を生成した場合に、当該塩素系物質の溶液２００中の濃度むらを抑制することができる。さらには、静電霧化装置１０３が循環部８０を有することにより、循環部８０が溶液２００を循環する際に生じる循環圧によって、ノズル２６へ溶液２００を供給することができるため、別途第１溶液槽１０内の溶液２００をノズル２６へ送液するためのポンプ等が不要となり、構造が簡略化される。 According to such a configuration, the solution 200 accommodated in each of the first solution tank 10 and the second solution tank 11 is transferred from one of the first solution tank 10 and the second solution tank 11 to the other. Since the solution 200 is moved, the solution 200 can be easily stirred, so that bubbles or the like in the solution 200 that adversely affect the generation of the mist M can be removed. In addition, when a chlorine-based substance having a bactericidal effect such as hypochlorous acid is generated by electrolysis, uneven concentration of the chlorine-based substance in the solution 200 can be suppressed. Furthermore, since the electrostatic atomizer 103 includes the circulation unit 80, the solution 200 can be supplied to the nozzle 26 by the circulation pressure generated when the circulation unit 80 circulates the solution 200. A pump or the like for feeding the solution 200 in the solution tank 10 to the nozzle 26 becomes unnecessary, and the structure is simplified.
　なお、実施の形態３に係る静電霧化装置１０３は、実施の形態２に係る静電霧化装置１０１と同様に、イオン透過膜１４０をさらに備えてもよい。こうすることで、実施の形態３に係る静電霧化装置１０３は、実施の形態２に係る静電霧化装置１０１と同様の効果をさらに得ることができる。 Note that the electrostatic atomizer 103 according to the third embodiment may further include an ion permeable membrane 140 as in the electrostatic atomizer 101 according to the second embodiment. By doing so, the electrostatic atomizer 103 according to Embodiment 3 can further obtain the same effects as the electrostatic atomizer 101 according to Embodiment 2.
