Description

本発明は、静電霧化現象によりナノメータサイズのイオンミストを発生させる静電霧化装置に関するものである。   The present invention relates to an electrostatic atomizer that generates nanometer-sized ion mist by an electrostatic atomization phenomenon.

従来から、霧化電極部である霧化針と、該霧化針の先端に対向して位置する相手側電極部（対向電極部）と、霧化針に水を供給する供給手段とを備え、霧化針と相手側電極部との間に高電圧を印加することで霧化針に保持される水を霧化させてナノメータサイズで強い電荷を持つイオンミスト（以下、これをナノイオンミストという）を発生させる静電霧化装置が、特許文献１、特許文献２、特許文献３等により知られている。   Conventionally, an atomizing needle that is an atomizing electrode part, a counterpart electrode part (opposite electrode part) that faces the tip of the atomizing needle, and a supply means that supplies water to the atomizing needle are provided. , An ion mist having a strong charge in the nanometer size by atomizing water held in the atomization needle by applying a high voltage between the atomization needle and the counterpart electrode part (hereinafter referred to as nano ion mist) ) Is known from Patent Document 1, Patent Document 2, Patent Document 3, and the like.

上記のような静電霧化装置で生成した帯電微粒子水は、粒径が３〜数十ｎｍ程度であって、人体の角質細胞の大きさである７０ｎｍよりも小さな粒径であるため、広範囲に飛散し、滞留時間が長く、壁面などの内部にも浸透し、高い脱臭効果や殺菌効果を発揮することができ、また、皮膚に対してはナノイオンミストの暴露により角質層表面の奥までも水分が十分に補給されて、高い保湿効果が得られ、また、毛髪の保湿効果等の効果も得られるようになっているので、多様な商品に備えることで多様な効果が得られるものである。   The charged fine particle water generated by the electrostatic atomizer as described above has a particle size of about 3 to several tens of nm and a particle size smaller than 70 nm which is the size of the keratinocytes of the human body. It has a long residence time, penetrates into the interior of walls, etc., and exhibits high deodorizing and bactericidal effects. Moisture is sufficiently replenished to obtain a high moisturizing effect, and hair moisturizing effect and the like can be obtained. By preparing for various products, various effects can be obtained. .

ところが、上記した特許文献１、特許文献２、特許文献３等に示される従来の静電霧化装置は、霧化針と相手側電極部との間で空中放電をさせて霧化針の先端に供給した水を静電霧化して帯電微粒子水を生成するようにしていた。   However, the conventional electrostatic atomizers disclosed in Patent Document 1, Patent Document 2, Patent Document 3, and the like described above cause air discharge between the atomization needle and the counterpart electrode portion to cause the tip of the atomization needle to be discharged. The water supplied to is electrostatically atomized to generate charged fine particle water.

このような空中放電により霧化針の先端部に保持した水を静電霧化するには、霧化電極部を構成する霧化針は先端が尖った極細の針状に形成する必要があり、３次元の精密加工となって製作が難しく、特に、霧化針の先端の放電部となる部分の加工が難しく、コストも高くなるという問題があった。   In order to electrostatically atomize the water retained at the tip of the atomization needle by such an air discharge, the atomization needle constituting the atomization electrode must be formed into a very fine needle shape with a sharp tip. Manufacturing is difficult due to the three-dimensional precision processing, and in particular, there is a problem that processing of the portion that becomes the discharge portion at the tip of the atomizing needle is difficult and the cost increases.

また、霧化針を熱交換器の冷却部により直接冷却して空気中の水分を結露させることで霧化針に水を供給するに当たり、上記のように霧化針が極細の針状であるため、表面積が小さく、必要量の結露水を安定して得難いという問題があった。   In addition, when the atomization needle is directly cooled by the cooling unit of the heat exchanger to condense moisture in the air to supply water to the atomization needle, the atomization needle has an extremely fine needle shape as described above. Therefore, there has been a problem that the surface area is small and it is difficult to stably obtain the necessary amount of condensed water.

更に、針状をした霧化針と、霧化針の先端に対して空間を介して対向する相手側電極部とをハウジングに支持し、更に、霧化針の後端部側にペルチェユニットを配置するという構造であるため、構造が複雑になると共に、組み立てが面倒で、また、組み立て精度にばらつきがあると、霧化針と相手側電極部との間の距離の精度が悪くなり、目的とする静電霧化が得られなくなり、また、薄型にできず、装置全体が大型化してしまうという問題があった。
特開２００６−６８７１１号公報 特開２００５−１３１５４９号公報 特開２００４−３５８３６４号公報 Furthermore, a needle-shaped atomizing needle and a counterpart electrode part facing the tip of the atomizing needle through a space are supported by the housing, and a Peltier unit is further provided on the rear end side of the atomizing needle. Since the structure is arranged, the structure becomes complicated, the assembly is troublesome, and if the assembly accuracy varies, the accuracy of the distance between the atomizing needle and the counterpart electrode part deteriorates. There is a problem in that the electrostatic atomization cannot be obtained, the thickness cannot be reduced, and the entire apparatus is enlarged.

本発明は上記の従来の問題点に鑑みて発明したものであって、沿面放電により帯電微粒子水を生成するための静電霧化ができて構造が簡略化し、精度が良く、製作コストも安く、また、装置のコンパクト化が図れる静電霧化装置を提供することを課題とするものである。   The present invention has been invented in view of the above-described conventional problems, and can be electrostatically atomized to generate charged fine particle water by creeping discharge, simplifying the structure, improving accuracy, and reducing manufacturing costs. Another object of the present invention is to provide an electrostatic atomizer that can be made compact.

上記課題を解決するために本発明に係る静電霧化装置は、絶縁体１の外面に設けたられた霧化電極部２と、絶縁体１の外面に上記霧化電極部２に対して離して設けられた相手側電極部３と、霧化電極部２に水を供給するための水供給手段４と、霧化電極部２に供給された水に高電圧を印加するための高電圧印加手段５とを備え、高電圧印加手段５により高電圧を印加することで霧化電極部２と相手側電極部３との間で絶縁体１の外面に沿った沿面放電を発生させて霧化電極部２に供給された水を静電霧化することを特徴とするものである。   In order to solve the above-mentioned problem, an electrostatic atomizer according to the present invention is provided with an atomizing electrode portion 2 provided on the outer surface of the insulator 1 and the atomizing electrode portion 2 on the outer surface of the insulator 1. The counterpart electrode part 3 provided at a distance, the water supply means 4 for supplying water to the atomizing electrode part 2, and the high voltage for applying a high voltage to the water supplied to the atomizing electrode part 2 The application means 5 is provided, and a high voltage is applied by the high voltage application means 5 to generate a creeping discharge along the outer surface of the insulator 1 between the atomizing electrode portion 2 and the counterpart electrode portion 3 to generate fog. The water supplied to the chemical electrode part 2 is electrostatically atomized.

このように、霧化電極部２に供給された水を沿面放電により静電霧化して帯電微粒子水を生成することができ、従来の霧化針の先端部に供給された水を空中放電により静電霧化するものに比べて、霧化電極部２の構造が簡単な構造となり、装置の組み立てが容易で、精度も高くなり、また、製作コストも安くなり、コンパクト化が図れ、また、沿面放電により静電霧化するので、高電圧をかけなくても大電流を流すことができる。   As described above, the water supplied to the atomizing electrode unit 2 can be electrostatically atomized by creeping discharge to generate charged fine particle water, and the water supplied to the tip of the conventional atomizing needle can be generated by air discharge. Compared with the electrostatic atomizing device, the structure of the atomizing electrode unit 2 is simple, the assembly of the device is easy, the accuracy is high, the manufacturing cost is low, and the size can be reduced. Since electrostatic atomization is caused by creeping discharge, a large current can flow without applying a high voltage.

また、絶縁体１の外面の霧化電極部２と、相手側電極部３との間に遮水部６を設けることが好ましい。   Moreover, it is preferable to provide the water shielding part 6 between the atomizing electrode part 2 on the outer surface of the insulator 1 and the counterpart electrode part 3.

このような構成とすることで、絶縁体１の外面に設けた霧化電極部２と相手側電極部３との間が水によって短絡するのが防止され、霧化電極部２に供給された水を沿面放電により確実に静電霧化することができる。   By setting it as such a structure, it is prevented that the atomization electrode part 2 provided in the outer surface of the insulator 1 and the other party electrode part 3 are short-circuited with water, and the atomization electrode part 2 was supplied. Water can be reliably atomized by creeping discharge.

また、絶縁体１の一外面に霧化電極部２と相手側電極部３とを設けることが好ましい。   Moreover, it is preferable to provide the atomizing electrode part 2 and the counterpart electrode part 3 on one outer surface of the insulator 1.

このような構成とすることで、装置をコンパクト化できる。   With such a configuration, the apparatus can be made compact.

また、絶縁体１の一外面に霧化電極部２を設けると共に絶縁体１の上記霧化電極部２を設けた一外面とは異なる他の外面に相手側電極部３を設けることが好ましい。   Moreover, it is preferable to provide the other electrode part 3 on the outer surface different from the one outer surface provided with the atomizing electrode part 2 of the insulator 1 while providing the atomizing electrode part 2 on one outer surface of the insulator 1.

このような構成とすることで、霧化電極部２と相手側電極部３とが水で接続されて短絡するのを防止できる。   By setting it as such a structure, it can prevent that the atomization electrode part 2 and the other party electrode part 3 are connected with water, and are short-circuited.

また、絶縁体１の外面に面状をした霧化電極部２を形成し、霧化電極部２に絶縁部８を介して該霧化電極部２を冷却するための熱交換器７を設け、霧化電極部２を冷却することで空気中の水分を結露させて霧化電極部２の表面に水を供給することが好ましい。   Further, the atomizing electrode portion 2 having a planar shape is formed on the outer surface of the insulator 1, and the atomizing electrode portion 2 is provided with a heat exchanger 7 for cooling the atomizing electrode portion 2 via the insulating portion 8. It is preferable that water in the air is condensed by cooling the atomizing electrode part 2 to supply water to the surface of the atomizing electrode part 2.

このような構成とすることで、面状をした霧化電極部２を冷却して霧化電極部２に結露水を生成するので、面状で面積が広くなった霧化電極部２に確実に安定して結露水を生成することができる。   By adopting such a configuration, the atomized electrode portion 2 having a planar shape is cooled to generate condensed water in the atomized electrode portion 2, so that the atomized electrode portion 2 having a planar shape and a large area can be reliably provided. Can stably generate condensed water.

本発明は、上記のように構成したので、沿面放電により霧化電極部に供給された水を静電霧化して帯電微粒子水を生成することができ、霧化電極部の構造が簡略化すると共に装置の構造も簡略化し、精度が良く、製作コストも安く、また、装置のコンパクト化が図れる。   Since the present invention is configured as described above, the charged fine particle water can be generated by electrostatic atomization of water supplied to the atomization electrode portion by creeping discharge, and the structure of the atomization electrode portion is simplified. In addition, the structure of the device is simplified, the accuracy is high, the manufacturing cost is low, and the device can be made compact.

以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

絶縁体１の外面に霧化電極部２と、相手側電極部３とが離して設けてある。添付図面に示す実施形態においては、導電材料よりなる霧化電極部２と、導電材料よりなる相手側電極部３とをセラミックのような絶縁体１の外面に設けてある。   An atomizing electrode portion 2 and a counterpart electrode portion 3 are provided apart from each other on the outer surface of the insulator 1. In the embodiment shown in the accompanying drawings, an atomizing electrode portion 2 made of a conductive material and a counterpart electrode portion 3 made of a conductive material are provided on the outer surface of an insulator 1 such as ceramic.

導電材料よりなる霧化電極部２、相手側電極部３を絶縁体１の外面に設けるに当っては、例えば、金属箔や金属板を板状をした絶縁体１の外面に取着して、エッチングすることで、絶縁体１の外面に所定形状の霧化電極部２や相手側電極部３を形成したり、あるいは、金属箔や金属板であらかじめ所定の形状に形成した霧化電極部２や相手側電極部３をそれぞれ絶縁体１の外面に取着したり、あるいは、導電性材料を印刷により絶縁体１の外面に印刷することで、絶縁体１の外面に所定形状の霧化電極部２や相手側電極部３を形成したりすることができる。いずれにせよ、従来の空中放電により静電霧化するための霧化電極部のような精密な３次元加工を必要とすることなく、簡単且つ精度よく霧化電極部２、相手側電極部３を形成できる。   In providing the atomizing electrode part 2 and the counterpart electrode part 3 made of a conductive material on the outer surface of the insulator 1, for example, a metal foil or a metal plate is attached to the outer surface of the plate-like insulator 1. The atomizing electrode part 2 and the counterpart electrode part 3 having a predetermined shape are formed on the outer surface of the insulator 1 by etching, or the atomizing electrode part previously formed in a predetermined shape with a metal foil or a metal plate 2 or the mating electrode part 3 is attached to the outer surface of the insulator 1, or a conductive material is printed on the outer surface of the insulator 1 by printing to form an atomized atom on the outer surface of the insulator 1. The electrode part 2 and the counterpart electrode part 3 can be formed. In any case, the atomizing electrode unit 2 and the counterpart electrode unit 3 can be easily and accurately obtained without the need for precise three-dimensional processing such as the conventional atomizing electrode unit for electrostatic atomization by air discharge. Can be formed.

霧化電極部２は面状をしていて、端部に先端が尖った尖部９を設けてある。図１に示す実施形態では霧化電極部２が円板状をしていて、外周縁部に周方向に連続して複数の尖部９を設けた例であり、図２、図３に示す実施形態では霧化電極部２が帯板状をしていて長手方向の一端部に先端が尖った尖部９を設けた例である。   The atomizing electrode portion 2 has a planar shape, and has a pointed portion 9 with a sharp tip at the end. The embodiment shown in FIG. 1 is an example in which the atomizing electrode portion 2 has a disk shape, and a plurality of cusps 9 are provided continuously in the circumferential direction on the outer peripheral edge portion, as shown in FIGS. The embodiment is an example in which the atomizing electrode portion 2 has a band plate shape and a pointed portion 9 having a sharp tip is provided at one end portion in the longitudinal direction.

霧化電極部２には高電圧印加手段５が接続してある。また、添付図面に示す実施形態では相手側電極部３はフレームグランド（例えば、本発明の静電霧化装置を組み込む電気機器などのフレーム）に接続してあるが、高電圧印加手段５の一端部を霧化電極部２に、他端を相手側電極部３に接続するものであってもよい。   High voltage application means 5 is connected to the atomizing electrode section 2. Further, in the embodiment shown in the accompanying drawings, the counterpart electrode unit 3 is connected to a frame ground (for example, a frame of an electric device incorporating the electrostatic atomizer of the present invention). The part may be connected to the atomizing electrode part 2 and the other end connected to the counterpart electrode part 3.

また、霧化電極部２に水を供給するための水供給手段４が設けてある。水供給手段４として添付図面に示す実施形態では熱交換器７の例が示してある。   Further, water supply means 4 for supplying water to the atomizing electrode unit 2 is provided. In the embodiment shown in the accompanying drawings as the water supply means 4, an example of the heat exchanger 7 is shown.

熱交換器７としては、例えば、ペルチェユニットを用いることができる。ペルチェユニットは、熱伝導性の高いアルミナや窒化アルミニウムから成る絶縁板の片面側に回路を形成してある一対のペルチェ回路板を、互いの回路側が向い合うように対向させ、多数列設してあるＢｉＴｅ系の熱電素子を両ペルチェ回路板間で挟持するとともに隣接する熱電素子同士を両側の回路で電気的に接続させ、熱電素子への通電により一方のペルチェ回路板側から他方のペルチェ回路板側に向けて熱が移動するように設けたものであり、上記ペルチェユニットの一方の側が冷却側、他方の側が放熱側となっている。この熱交換器７を構成するペルチェユニットの冷却側を絶縁部８を介して霧化電極部２に接続し、霧化電極部２を冷却することで、空気中の水分が霧化電極部２に結露水として生成することで、霧化電極部２に水を供給するようになっている。   As the heat exchanger 7, for example, a Peltier unit can be used. The Peltier unit consists of a pair of Peltier circuit boards that form a circuit on one side of an insulating plate made of alumina or aluminum nitride with high thermal conductivity, facing each other so that the circuit sides face each other. A BiTe-based thermoelectric element is sandwiched between both Peltier circuit boards, and adjacent thermoelectric elements are electrically connected to each other by circuits on both sides. It is provided so that heat moves toward the side, and one side of the Peltier unit is a cooling side, and the other side is a heat dissipation side. By connecting the cooling side of the Peltier unit constituting the heat exchanger 7 to the atomizing electrode unit 2 through the insulating unit 8 and cooling the atomizing electrode unit 2, moisture in the air is atomized electrode unit 2. The water is supplied to the atomizing electrode unit 2 by generating as condensed water.

図１に示す実施形態では、絶縁体１の外面に設けた霧化電極部２の絶縁体１の外面と反対側の面に絶縁部８を介して熱交換器７の冷却側を接続した例である。   In the embodiment shown in FIG. 1, an example in which the cooling side of the heat exchanger 7 is connected to the surface opposite to the outer surface of the insulator 1 of the atomizing electrode portion 2 provided on the outer surface of the insulator 1 via the insulating portion 8. It is.

また、図２、図３に示す実施形態では、霧化電極部２及び相手側電極部３を外面に設けた絶縁体１に熱交換器７の冷却側を取付けた例であり、この実施形態では霧化電極部２及び相手側電極部３を設ける絶縁体１が、熱交換器７の冷却側と霧化電極部２との間に介在される絶縁部８を構成している。   Moreover, in embodiment shown in FIG. 2, FIG. 3, it is an example which attached the cooling side of the heat exchanger 7 to the insulator 1 which provided the atomization electrode part 2 and the other party electrode part 3 in the outer surface, and this embodiment Then, the insulator 1 which provides the atomizing electrode part 2 and the counterpart electrode part 3 constitutes an insulating part 8 interposed between the cooling side of the heat exchanger 7 and the atomizing electrode part 2.

この図２、図３に示す実施形態において、板状をした絶縁体１の霧化電極部２を設けた一外面（表側外面）と反対側の他の外面（裏側外面）の上記霧化電極部２に表裏対応する部位に熱交換器７の冷却側を取付けてある。したがって、絶縁体１は熱交換器７の冷却側が取着してある部分が最も冷却される。一方、セラミックのような絶縁体１は金属などに比べると熱を伝え難いが、絶縁体１を板状として薄く形成することで、熱交換器７の冷却側が取着された部分に対応した霧化電極部２を効果的に冷却して霧化電極部２部分に結露水を生成することができる。一方、絶縁体１の外面の霧化電極部２を設けた部分以外の部分は熱交換器７の冷却側との距離が長くなり、霧化電極部２から離れるほどその距離は長くなって熱が伝わりにくく、したがって、絶縁体１の外面の霧化電極部２を設けた部分から離れた部分では結露水ができ難くなっている。   In the embodiment shown in FIGS. 2 and 3, the atomizing electrode on the other outer surface (backside outer surface) opposite to the outer surface (front side outer surface) provided with the atomizing electrode portion 2 of the plate-like insulator 1 is provided. The cooling side of the heat exchanger 7 is attached to the part corresponding to the front and back of the part 2. Therefore, the insulator 1 is most cooled at the portion where the cooling side of the heat exchanger 7 is attached. On the other hand, the insulator 1 such as a ceramic is less likely to transmit heat than a metal or the like, but by forming the insulator 1 as a thin plate, a mist corresponding to the portion where the cooling side of the heat exchanger 7 is attached. The atomizing electrode part 2 can be effectively cooled to generate condensed water in the atomizing electrode part 2 part. On the other hand, the portion of the outer surface of the insulator 1 other than the portion where the atomizing electrode portion 2 is provided has a longer distance from the cooling side of the heat exchanger 7, and the distance from the atomizing electrode portion 2 increases as the distance increases. Therefore, it is difficult to form dew condensation water at a portion away from the portion provided with the atomizing electrode portion 2 on the outer surface of the insulator 1.

そして、本発明においては、上記のように熱交換器７の冷却側で霧化電極部２を冷却して、空気中の水分を霧化電極部２に結露水として供給すると共に、高電圧印加手段５により上記霧化電極部２に供給された水に高電圧を印加すると、高電圧印加手段５により高電圧を印加することで霧化電極部２と相手側電極部３との間で絶縁体１の外面に沿った沿面放電が発生して霧化電極部２に供給された水が静電霧化される。すなわち、霧化電極部２に供給された水は高電圧が印加することで帯電し、帯電した水にクーロン力が働き、霧化電極部２の端部の尖部９に沿って相手側電極部３側に引かれ、その先端に電荷が集中して電荷の密度が高密度となり、先端部分の水が大きなエネルギー（高密度となった電荷の反発力）を受けて表面張力を超えてはじけるようにして水が***・飛散（レイリー***）を繰り返して静電霧化を行い、活性種（ラジカル）を含むナノメータサイズの帯電微粒子水が発生する。   And in this invention, while atomizing electrode part 2 is cooled by the cooling side of heat exchanger 7 as mentioned above, while supplying the moisture in the air to atomizing electrode part 2 as a dew condensation water, high voltage application When a high voltage is applied to the water supplied to the atomizing electrode unit 2 by the means 5, the high voltage is applied by the high voltage applying means 5 to insulate between the atomizing electrode part 2 and the counterpart electrode part 3. Creeping discharge along the outer surface of the body 1 is generated, and water supplied to the atomizing electrode unit 2 is electrostatically atomized. That is, the water supplied to the atomizing electrode part 2 is charged by applying a high voltage, and the Coulomb force acts on the charged water, and the counter electrode along the apex 9 at the end of the atomizing electrode part 2 Pulled to the side of the part 3, the charge concentrates on the tip and the charge density becomes high, and the water at the tip part receives large energy (repulsive force of the charge that has become high density) and repels over the surface tension. In this way, the water is repeatedly atomized and scattered (Rayleigh fission) to perform electrostatic atomization, and nanometer-sized charged fine particle water containing active species (radicals) is generated.

このナノメータサイズの帯電微粒子水はナノメータサイズと極めて小さいために空気中に長時間浮遊すると共に拡散性が高いため、霧化対象空間内の隅々まで浮遊して、霧化対象空間の内面や霧化対象空間内に収納した収納物に付着するものであり、しかも、ナノメータサイズの帯電微粒子水は活性種が水分子に包み込まれるようにして存在するため脱臭効果、カビや菌の除菌や繁殖の抑制効果があり、また、活性種が水分子に包み込まれるようにして存在するナノメータサイズの帯電微粒子水は遊離基単独で存在する場合より寿命が長いため、上記拡散性、脱臭効果、カビや菌の除菌や繁殖の抑制効果がより向上することになる。また、ナノメータサイズの帯電微粒子水は保湿効果があるため、保湿する効果がある。   Since this nanometer-sized charged fine particle water is extremely small as nanometer size, it floats in the air for a long time and has high diffusivity, so it floats to every corner of the atomization target space, The nanometer-sized charged fine particle water is present in such a way that the active species are encapsulated in water molecules, and thus deodorizing effect, mold and fungus sterilization and propagation In addition, the nanometer-sized charged fine particle water that exists in such a manner that the active species is encapsulated in water molecules has a longer life than the case where it exists as a free radical alone, so that the diffusibility, deodorizing effect, mold and The sterilization effect of bacteria and the suppression effect of reproduction will be further improved. In addition, since nanometer-sized charged fine particle water has a moisturizing effect, it has an effect of moisturizing.

ここで、絶縁体１の外面の霧化電極部２と、相手側電極部３との間に遮水部６を設けることで、霧化電極部２に供給された水が絶縁体１の外面にこぼれたり、あるいは、絶縁体１の外面の霧化電極部２の近くで仮に結露水が発生することがあっても、該結露水が霧化電極部２から離れた相手側電極部３までつながるのを遮水部６で防止することができ、これにより短絡が生じないようにできる。   Here, by providing the water shielding portion 6 between the atomizing electrode portion 2 on the outer surface of the insulator 1 and the counterpart electrode portion 3, the water supplied to the atomizing electrode portion 2 is the outer surface of the insulator 1. Even if spillage occurs or dew condensation water is generated near the atomization electrode part 2 on the outer surface of the insulator 1, the dew condensation water is separated from the atomization electrode part 2 to the counterpart electrode part 3. Connection can be prevented by the water-impervious portion 6, thereby preventing a short circuit from occurring.

図３の実施形態では絶縁体１の外面の霧化電極部２と、相手側電極部３との間に突部を設けて水を遮水する遮水部６を設けた例であるが、突部の代わりに凹溝を形成して遮水部６としてもよい。   In the embodiment of FIG. 3, it is an example in which a water shielding portion 6 that shields water by providing a protrusion between the atomizing electrode portion 2 on the outer surface of the insulator 1 and the counterpart electrode portion 3 is provided. It is good also as a water shielding part 6 by forming a ditch | groove instead of a protrusion.

また、図１、図２に示す実施形態では絶縁体１の一外面に霧化電極部２を形成し、霧化電極部２を設けた一外面とは異なる他の外面に相手側電極部３を設けることで、絶縁体１の一外面の端部と他の外面の端部との間に部分（絶縁体１の一外面の端部と他の外面の端部とが一致している場合もある）、つまり、絶縁体１の一端部が水切部分となって遮水部６を構成している例である。   Moreover, in embodiment shown in FIG. 1, FIG. 2, the atomization electrode part 2 is formed in one outer surface of the insulator 1, and the other party electrode part 3 is provided in the other outer surface different from the one outer surface which provided the atomization electrode part 2. In FIG. Is provided between the end portion of one outer surface of the insulator 1 and the end portion of the other outer surface (when the end portion of one outer surface of the insulator 1 and the end portion of the other outer surface coincide with each other). In other words, this is an example in which one end portion of the insulator 1 is a drained portion to constitute the water shielding portion 6.

また、図１の実施形態のように、絶縁体１とは別の絶縁部８を介して熱交換器７の冷却側を霧化電極部２に接続したものにおいては、絶縁体１を冷却することなく霧化電極部２のみを効果的に冷却して、霧化電極部２に効果的に結露水を生成することができる。   Further, as in the embodiment of FIG. 1, the insulator 1 is cooled in the case where the cooling side of the heat exchanger 7 is connected to the atomizing electrode portion 2 via the insulating portion 8 different from the insulator 1. It is possible to effectively cool only the atomizing electrode part 2 without generating condensed water in the atomizing electrode part 2 effectively.

霧化電極部２には表面に結露した水をスムーズに端部の尖部９に供給できるように尖部９側に向かう導水溝を形成したり、あるいは、霧化電極部２の表面を尖部９側に向けて僅かに下り傾斜するように傾斜面としたり、あるいは、霧化電極部２を多孔質として毛細管現象により端部の尖部９側に水を供給するようにしたりするのが好ましい。   The atomizing electrode part 2 is formed with a water guide groove toward the apex 9 side so that water condensed on the surface can be smoothly supplied to the apex 9 at the end, or the surface of the atomizing electrode part 2 is sharpened. The inclined surface may be slightly inclined downward toward the portion 9 side, or the atomizing electrode portion 2 may be made porous to supply water to the end portion 9 side by capillary action. preferable.

また、上記実施形態においては、霧化電極部２に水を供給する水供給手段４としてペルチェユニットのような熱交換器７を用い、該熱交換器７の冷却側を絶縁部８を介して霧化電極部２に接続した例を示したが、熱交換器７の冷却側に絶縁手段を介して冷却板を接続し、該冷却板を冷却することで空気中の水分を冷却板に結露水として生成し、該冷却板に生成した結露水を冷却板に直接接続した、又は通水性を有する接続部材を介して接続した霧化電極部２に供給するようにしたり、あるいは、上記冷却板で生成した結露水を多孔質体あるいは容器よりなる保水部に溜め、保水部に溜めた水を保水部に直接接続した、あるいは、通水性を有する接続部材を介して接続した霧化電極部２に供給するようにしてもよい。これらの実施形態の場合、霧化電極部２としては、供給される水を端部の尖部９側に毛細管現象により供給する多孔質のものが好ましく、この場合には霧化電極部２としては必ずしも金属である必要はない。   Moreover, in the said embodiment, the heat exchanger 7 like a Peltier unit is used as the water supply means 4 which supplies water to the atomization electrode part 2, and the cooling side of this heat exchanger 7 is passed through the insulation part 8. Although the example which connected to the atomization electrode part 2 was shown, the cooling plate was connected to the cooling side of the heat exchanger 7 via an insulating means, and the water in the air was condensed on the cooling plate by cooling the cooling plate. It is generated as water and the condensed water generated on the cooling plate is supplied to the atomizing electrode portion 2 connected directly to the cooling plate or connected through a connecting member having water permeability, or the cooling plate The condensate water generated in step 1 is stored in a water holding part made of a porous body or a container, and the water stored in the water holding part is directly connected to the water holding part or connected through a connecting member having water permeability. You may make it supply to. In the case of these embodiments, the atomizing electrode part 2 is preferably a porous one that supplies the supplied water to the end 9 at the end by capillarity, and in this case, as the atomizing electrode part 2 Need not be metal.

また、水供給手段４としては、他の例として水タンクをあげることができ、水タンクに溜めた水を任意の搬送手段で霧化電極部２に供給するようにしてもよい。   As another example of the water supply means 4, a water tank can be used, and the water stored in the water tank may be supplied to the atomization electrode unit 2 by an arbitrary transport means.
