[Embodiment 1]
　図１から図３を参照して、実施形態１に係る放電装置１００を説明する。 The discharge device 100 according to the first embodiment will be described with reference to Figures 1 to 3.
　図１は、実施形態１の放電装置１００を示す一部切欠き斜視図である。図２は、実施形態１の放電装置１００における縦断面を拡大して示す斜視図である。図３は、実施形態１の放電装置１００が備える本体６０のケース６１及びカバー６５を拡大して示す分解斜視図である。 FIG. 1 is a partially cutaway perspective view showing the discharge device 100 of embodiment 1. FIG. 2 is an enlarged perspective view showing a vertical cross section of the discharge device 100 of embodiment 1. FIG. 3 is an enlarged exploded perspective view showing the case 61 and cover 65 of the main body 60 of the discharge device 100 of embodiment 1.
　図１に示されるように、放電装置１００は、コネクタ７０と、昇圧部８１と、放電電極３０と、本体６０とを備える。コネクタ７０は、外部から電圧が印加される。昇圧部８１は、電子部品群８０の一部であるプリント基板及び昇圧トランス（いずれも不図示）等から構成され、コネクタ７０に印加された電圧を昇圧する。放電電極３０は、昇圧部８１で昇圧された電圧により放電する。本体６０は、コネクタ７０及び放電電極３０を収容する。本体６０は、放電電極３０を囲う開口部６６と、所定方向から折り返された複数の折返部５０とを有する。複数の折返部５０は、少なくとも１つが開口部６６に形成されている。したがって、折返部５０は、本体６０における沿面経路４０に位置する。沿面経路４０は、放電電極３０の放電による電荷がコネクタ７０まで流れるおそれのある経路であるが、折返部５０により電荷の流れが妨げられる。 As shown in FIG. 1, the discharge device 100 includes a connector 70, a booster 81, a discharge electrode 30, and a main body 60. A voltage is applied to the connector 70 from the outside. The booster 81 is composed of a printed circuit board and a step-up transformer (neither of which are shown) that are part of an electronic component group 80, and boosts the voltage applied to the connector 70. The discharge electrode 30 discharges using the voltage boosted by the booster 81. The main body 60 houses the connector 70 and the discharge electrode 30. The main body 60 has an opening 66 that surrounds the discharge electrode 30, and multiple folded parts 50 that are folded back from a predetermined direction. At least one of the multiple folded parts 50 is formed in the opening 66. Therefore, the folded parts 50 are located on the creeping path 40 in the main body 60. The creeping path 40 is a path through which electric charge due to discharge of the discharge electrode 30 may flow to the connector 70, but the folded parts 50 prevent the flow of electric charge.
　沿面経路４０は、折返部５０を複数有することにより、長く複雑になるので、電荷の流れを十分に妨げる。したがって、放電装置１００は、リーク電流を十分に抑えることができる。また、沿面経路４０が折返部５０を複数有するので、本体６０を大型化しなくても沿面経路４０が長くなる。したがって、放電装置１００は、大型化することなく、リーク電流を十分に抑えることができる。 The surface path 40 has multiple turn-back sections 50, making it long and complex, which adequately impedes the flow of charge. Therefore, the discharge device 100 can adequately suppress leakage current. Also, because the surface path 40 has multiple turn-back sections 50, the surface path 40 becomes long without the need to enlarge the main body 60. Therefore, the discharge device 100 can adequately suppress leakage current without enlarging its size.
　放電電極３０は、基端側が昇圧部８１に接続され、先端が放電する。放電電極３０は、ワイヤ電極（不図示）よりも、棒電極（不図示）又は針電極３０である方が好ましい。ワイヤ電極は、多数の導電繊維（例えば、金属繊維）を束状にした電極である。棒電極は、棒状の導電材料で構成される電極である。針電極３０は、先端が基端側よりも細い針状の導電材料で構成される電極である。 The base end of the discharge electrode 30 is connected to the booster section 81, and the tip discharges. The discharge electrode 30 is preferably a rod electrode (not shown) or a needle electrode 30 rather than a wire electrode (not shown). A wire electrode is an electrode made of a bundle of numerous conductive fibers (e.g., metal fibers). A rod electrode is an electrode made of a rod-shaped conductive material. A needle electrode 30 is an electrode made of a needle-shaped conductive material whose tip is thinner than the base end.
　ワイヤ電極は、全ての導電繊維の先端から一斉に放電を行うのではなく、各導電繊維の先端から別個に放電を行う。一方、棒電極及び針電極３０は、単一の導電材料の先端から放電を行う。したがって、ワイヤ電極に比べて、棒電極及び針電極３０は、安定した放電を行う。特に、針電極３０は、先鋭化された針状、つまり、放電を行う先端の一点に電界が集中しやすい形状であるため、棒電極よりも安定した放電を行う。 A wire electrode does not discharge simultaneously from the tips of all conductive fibers, but rather discharges separately from the tip of each conductive fiber. On the other hand, rod electrodes and needle electrodes 30 discharge from the tip of a single conductive material. Therefore, compared to wire electrodes, rod electrodes and needle electrodes 30 discharge more stably. In particular, the needle electrode 30 has a sharpened needle shape, meaning that the shape makes it easy for the electric field to concentrate at the single point at the tip where the discharge occurs, and therefore discharges more stably than a rod electrode.
　ワイヤ電極では、コネクタ７０に近い側の導電繊維から放電する場合、コネクタ７０と放電する位置とが近くなると考えられる。言い換えれば、棒電極及び針電極３０では、ワイヤ電極よりも、コネクタ７０と放電する位置とが遠くなると考えられる。したがって、棒電極及び針電極３０では、ワイヤ電極よりも、放電によって発生した荷電性粒子に起因するコネクタ７０へのリーク電流を一層抑えられる。また、ワイヤ電極では、本体６０に近い側の導電繊維から放電する場合、放電による電荷が本体６０に蓄えられやすく（帯電しやすく）なると考えられる。言い換えれば、棒電極及び針電極３０では、ワイヤ電極よりも、放電による電荷が本体６０に蓄えられにくい（帯電しにくい）と考えられる。したがって、棒電極及び針電極では、ワイヤ電極よりも、本体６０の帯電によるリーク電流を一層抑えられる。 In the case of a wire electrode, when discharging from the conductive fiber closer to the connector 70, it is considered that the connector 70 and the discharge position are closer. In other words, in the case of a rod electrode and a needle electrode 30, it is considered that the connector 70 and the discharge position are farther away than in the case of a wire electrode. Therefore, in the case of a rod electrode and a needle electrode 30, it is possible to further suppress the leakage current to the connector 70 caused by the charged particles generated by the discharge than in the case of a wire electrode. Also, in the case of a wire electrode, it is considered that the charge due to the discharge is more likely to be stored (easily charged) in the main body 60 when discharging from the conductive fiber closer to the main body 60. In other words, in the case of a rod electrode and a needle electrode 30, it is considered that the charge due to the discharge is less likely to be stored (easily charged) in the main body 60 than in the case of a wire electrode. Therefore, in the case of a rod electrode and a needle electrode, it is possible to further suppress the leakage current due to the charging of the main body 60 than in the case of a wire electrode.
　放電装置１００は、１つの放電電極３０を備えてもよく、２つ以上の放電電極３０，３５を備えてもよい。放電装置１００が２つ以上の放電電極３０，３５を備える場合、少なくともコネクタ７０に最も近い側の放電電極３０からの沿面経路４０に、複数の折返部５０が形成されていればよい。リーク電流が発生しやすいのは、コネクタ７０に最も近い側の放電電極３０だからである。 The discharge device 100 may include one discharge electrode 30, or two or more discharge electrodes 30, 35. When the discharge device 100 includes two or more discharge electrodes 30, 35, it is sufficient that a plurality of folds 50 are formed on the creeping path 40 from at least the discharge electrode 30 closest to the connector 70. This is because it is the discharge electrode 30 closest to the connector 70 that is most susceptible to leak current.
　例えば、２つの放電電極３０，３５のうちの一方は、放電することにより正イオンを放出する。正イオンは、水素イオン（Ｈ+）の周囲に複数の水分子がクラスター化したクラスターイオン［Ｈ+（Ｈ2Ｏ）m（ｍは零以上の任意の正数）］である。さらに、例えば、２つの放電電極３０，３５のうちの他方は、放電することにより負イオンを放出する。負イオンは、酸素イオン（Ｏ2 -）の周囲に複数の水分子がクラスター化したクラスターイオン［Ｏ2 -（Ｈ2Ｏ）n（ｎは零以上の任意の正数）］である。 For example, one of the two discharge electrodes 30, 35 emits positive ions when discharged. The positive ions are cluster ions [H + ( H2O ) m (m is any positive number equal to or greater than zero)] in which a plurality of water molecules are clustered around a hydrogen ion (H + ). Furthermore, for example, the other of the two discharge electrodes 30, 35 emits negative ions when discharged. The negative ions are cluster ions [ O2- ( H2O ) n (n is any positive number equal to or greater than zero)] in which a plurality of water molecules are clustered around an oxygen ion ( O2- ).
　コネクタ７０に近い側の放電電極３０が放電することにより正イオンを放出する場合、折返部５０で流れが妨げられる電荷は、正電荷である。一方、コネクタ７０に近い側の放電電極３０が放電することにより負イオンを放出する場合、折返部５０で流れが妨げられる電荷は、負電荷である。 When the discharge electrode 30 closer to the connector 70 discharges positive ions, the charge whose flow is impeded at the turn-around section 50 is positive. On the other hand, when the discharge electrode 30 closer to the connector 70 discharges negative ions, the charge whose flow is impeded at the turn-around section 50 is negative.
　図２に示されるように、複数の折返部５０は、放電電極３０から近い順に、第１折返部５１、第２折返部５２、及び、第３折返部５３である。第１折返部５１及び第３折返部５３の所定方向１３と、第２折返部５２の所定方向２０とが異なる。具体的には、第１折返部５１及び第３折返部５３の所定方向１３は、放電電極３０からコネクタ７０への方向（Ｘ方向）である。第２折返部５２の所定方向２０は、放電電極３０からコネクタ７０への方向に直交する方向（Ｚ方向）である。すなわち、複数の折返部５０は、いずれか折返部５１，５３の所定方向１３が、他の折返部５２の所定方向２０と異なる。 As shown in FIG. 2, the multiple fold portions 50 are, in order of proximity to the discharge electrode 30, a first fold portion 51, a second fold portion 52, and a third fold portion 53. The predetermined direction 13 of the first fold portion 51 and the third fold portion 53 is different from the predetermined direction 20 of the second fold portion 52. Specifically, the predetermined direction 13 of the first fold portion 51 and the third fold portion 53 is the direction from the discharge electrode 30 to the connector 70 (X direction). The predetermined direction 20 of the second fold portion 52 is a direction (Z direction) perpendicular to the direction from the discharge electrode 30 to the connector 70. In other words, among the multiple fold portions 50, the predetermined direction 13 of any of the fold portions 51, 53 is different from the predetermined direction 20 of the other fold portions 52.
　したがって、複数の折返部５０に付着した結露による水滴及び汚れ等が、自重により、いずれかの所定方向１３，２０に流れても、他の所定方向２０，１３に流れない。結果として、放電装置１００は、どのような姿勢であっても、水滴及び汚れ等の流れない折返部５０が確保される。よって、放電装置１００は、どのような姿勢であっても、リーク電流を十分に抑えることができる。 Therefore, even if water droplets and dirt due to condensation adhering to the multiple folded sections 50 flow in one of the specified directions 13, 20 due to their own weight, they do not flow in the other specified directions 20, 13. As a result, the discharge device 100 ensures that the folded sections 50 do not allow water droplets and dirt to flow, regardless of the position. Therefore, the discharge device 100 can sufficiently suppress leakage current, regardless of the position.
　図２に示されるように、いずれか折返部５１，５３の所定方向１３と、他の折返部５２の所定方向２０とは、直交することが好ましい。直交することにより、放電装置１００は、どのような姿勢であっても、水滴及び汚れ等の流れない折返部５０が確実に確保される。よって、放電装置１００は、どのような姿勢であっても、リーク電流を確実に抑えることができる。 As shown in FIG. 2, it is preferable that the predetermined direction 13 of any one of the folded portions 51, 53 is perpendicular to the predetermined direction 20 of the other folded portion 52. By making them perpendicular, the folded portion 50 is reliably secured so that water droplets, dirt, etc. do not flow, regardless of the position of the discharge device 100. Therefore, the discharge device 100 can reliably suppress leakage current, regardless of the position.
　本体６０は、保護枠６７を有する。保護枠６７は、放電電極３０の先端を保護する。保護枠６７は、複数の大通気口６８と、複数の小通気口６９とを有する。複数の小通気口６９のうち、放電電極３０に最も近い側は、第２折返部５２を構成する。保護枠６７は、開口部６６に設けられる。したがって、第２折返部５２は、開口部６６に形成されていると言える。 The main body 60 has a protective frame 67. The protective frame 67 protects the tip of the discharge electrode 30. The protective frame 67 has a number of large ventilation holes 68 and a number of small ventilation holes 69. Of the number of small ventilation holes 69, the side closest to the discharge electrode 30 constitutes the second folded portion 52. The protective frame 67 is provided in the opening 66. Therefore, it can be said that the second folded portion 52 is formed in the opening 66.
　図３に示されるように、本体６０は、ケース６１と、カバー６５とを有する。ケース６１は、コネクタ７０及び放電電極３０が配置される。カバー６５は、ケース６１に組み付けられる。ケース６１は、少なくとも放電電極３０とコネクタ７０との間で、カバー６５と密着している部分を有する。 As shown in FIG. 3, the main body 60 has a case 61 and a cover 65. The case 61 has the connector 70 and the discharge electrode 30 arranged therein. The cover 65 is attached to the case 61. The case 61 has a portion that is in close contact with the cover 65 at least between the discharge electrode 30 and the connector 70.
　放電電極３０とコネクタ７０との間では、ケース６１とカバー６５とが密着しているので、ケース６１とカバー６５との境界に隙間が無い。したがって、境界を介するリーク電流が発生しないので、リーク電流を十分に抑えることができる。 Between the discharge electrode 30 and the connector 70, the case 61 and the cover 65 are in close contact with each other, so there is no gap at the boundary between the case 61 and the cover 65. Therefore, no leakage current occurs through the boundary, and leakage current can be sufficiently suppressed.
　ケース６１は、仕切壁６２を有する。仕切壁６２は、放電電極３０を囲う。仕切壁６２は、例えば、平面視が矩形の枠状である。ケース６１において、カバー６５と密着するのは、仕切壁６２の上端である。仕切壁６２の上端のうち、カバー６５と密着するのは、少なくとも、放電電極３０とコネクタ７０との間に位置する一辺である。仕切壁６２の上端のうち、カバー６５と密着するのは、全ての辺（四辺）、つまり、全周であることが好ましい。密着する部分が多いほど、リーク電流が発生し得る経路を遮断するからである。 The case 61 has a partition wall 62. The partition wall 62 surrounds the discharge electrode 30. The partition wall 62 is, for example, in the shape of a rectangular frame in a plan view. In the case 61, it is the upper end of the partition wall 62 that comes into close contact with the cover 65. Of the upper end of the partition wall 62, at least one side that is located between the discharge electrode 30 and the connector 70 comes into close contact with the cover 65. Of the upper end of the partition wall 62, it is preferable that all sides (four sides), that is, the entire circumference, come into close contact with the cover 65. This is because the more parts that come into close contact, the more paths that can generate leakage current are blocked.
　カバー６５とケース６１との密着は、接着剤を使用した接着であること好ましい。接着剤を使用した接着であることにより、確実に隙間が防止されるからである。カバー６５とケース６１との密着には、爪等による係合ではなく、当接であることが好ましい。当接であることにより、製造を容易にすることができる。 The cover 65 and the case 61 are preferably bonded together using an adhesive. This is because bonding using an adhesive reliably prevents gaps. The cover 65 and the case 61 are preferably bonded together by abutment rather than engagement using claws or the like. Abutment makes manufacturing easier.
　ケース６１は、電子部品群８０をさらに有する。電子部品群８０は、仕切壁６２の内側に配置される。電子部品群８０は、コネクタ７０と放電電極３０とを電気的に接続する。電子部品群８０は、放電電極３０での放電を可能にするために、昇圧部８１と、各種電子部品（不図示）とを有する。 The case 61 further includes an electronic component group 80. The electronic component group 80 is disposed inside the partition wall 62. The electronic component group 80 electrically connects the connector 70 and the discharge electrode 30. The electronic component group 80 includes a booster section 81 and various electronic components (not shown) to enable discharge at the discharge electrode 30.
　ケース６１は、絶縁材料６３をさらに有する。絶縁材料６３は、仕切壁６２の内側に充填される。絶縁材料６３は、放電電極３０の基端側と、電子部品群８０とを埋設する。 The case 61 further includes an insulating material 63. The insulating material 63 is filled inside the partition wall 62. The insulating material 63 embeds the base end side of the discharge electrode 30 and the electronic component group 80.
　絶縁材料６３が放電電極３０の基端側を埋設することにより、リーク電流を十分に抑えることができる。また、絶縁材料６３が電子部品群８０を埋設することにより、電子部品群８０を保護することができる。絶縁材料６３は、樹脂であることが好ましい。絶縁材料６３が樹脂であれば、製造を容易にすることができる。
［実施形態２］ By embedding the base end side of the discharge electrode 30 in the insulating material 63, it is possible to sufficiently suppress leakage current. Furthermore, by embedding the electronic component group 80 in the insulating material 63, it is possible to protect the electronic component group 80. The insulating material 63 is preferably a resin. If the insulating material 63 is a resin, it is possible to facilitate manufacturing.
[Embodiment 2]
　次に、図４から図６を参照して、実施形態２に係る放電装置１００を説明する。実施形態２では、複数の折返部５０の位置が実施形態１と異なる。以下、実施形態２が実施形態１と異なる点を説明する。 Next, a discharge device 100 according to embodiment 2 will be described with reference to Figs. 4 to 6. In embodiment 2, the positions of the multiple folded portions 50 differ from embodiment 1. The differences between embodiment 2 and embodiment 1 will be described below.
　図４は、実施形態２の放電装置１００を示す斜視図である。図５は、実施形態２の放電装置１００を拡大して示す縦断面図である。図６は、実施形態２の放電装置１００の変形例を示す斜視図である。 FIG. 4 is a perspective view showing the discharge device 100 of embodiment 2. FIG. 5 is an enlarged longitudinal cross-sectional view showing the discharge device 100 of embodiment 2. FIG. 6 is a perspective view showing a modified example of the discharge device 100 of embodiment 2.
　図４に示されるように、カバー６５は、開口部６６を有する。開口部６６は、放電電極３０を囲う。複数の折返部５０は、開口部６６に形成される。複数の折返部５０の所定方向１３は、放電電極３０からコネクタ７０への方向と交差する。 As shown in FIG. 4, the cover 65 has an opening 66. The opening 66 surrounds the discharge electrode 30. The multiple folded portions 50 are formed in the opening 66. The predetermined direction 13 of the multiple folded portions 50 intersects with the direction from the discharge electrode 30 to the connector 70.
　複数の折返部５０の所定方向１３が放電電極３０からコネクタ７０への方向と交差することにより、沿面経路４０が長く複雑になるので、電荷の流れを十分に妨げる。したがって、放電装置１００は、リーク電流を十分に抑えることができる。また、複数の折返部５０が開口部６６に形成されているので、本体６０を大型化しなくても沿面経路４０が長くなる。したがって、放電装置１００は、大型化することなく、リーク電流を十分に抑えることができる。 The predetermined direction 13 of the multiple folds 50 intersects with the direction from the discharge electrode 30 to the connector 70, making the creeping path 40 long and complex, sufficiently impeding the flow of charge. Therefore, the discharge device 100 can sufficiently suppress leakage current. Also, because the multiple folds 50 are formed in the opening 66, the creeping path 40 becomes long without the need to increase the size of the main body 60. Therefore, the discharge device 100 can sufficiently suppress leakage current without increasing the size.
　放電電極３０からのコネクタ７０の方向は、例えば、放電電極３０からコネクタ７０への最短の方向（Ｘ方向）である。複数の折返部５０の所定方向１３（±Ｙ方向）と、放電電極３０からコネクタ７０への方向（Ｘ方向）とは、直交することが好ましい。直交することにより、複数の折返部５０が電荷の流れを一層妨げるので、リーク電流を一層抑えることができる。 The direction of the connector 70 from the discharge electrode 30 is, for example, the shortest direction from the discharge electrode 30 to the connector 70 (X direction). It is preferable that the predetermined direction 13 (±Y direction) of the multiple folded parts 50 and the direction from the discharge electrode 30 to the connector 70 (X direction) are perpendicular to each other. By making them perpendicular, the multiple folded parts 50 further hinder the flow of charge, thereby further suppressing leakage current.
　図４及び図５に示されるように、放電電極３０は、先端が開口部６６から突出する。具体的に説明すると、放電電極３０は、基端側が開口部６６からケース６１側（－Ｚ側）に突出し、先端が開口部６６からケース６１の反対側（Ｚ側）に突出する。 As shown in Figures 4 and 5, the tip of the discharge electrode 30 protrudes from the opening 66. More specifically, the base end of the discharge electrode 30 protrudes from the opening 66 towards the case 61 (-Z side), and the tip protrudes from the opening 66 to the opposite side of the case 61 (Z side).
　放電電極３０の先端を開口部６６から突出させれば、放電により放出するイオンを増やすことが可能である。一般に、放出するイオンが増えるにつれて、開口部６６に蓄えられる電荷（開口部６６への帯電）も増えるので、リーク電流が発生しやすくなる。しかしながら、開口部６６に複数の折返部５０が形成されていることで、リーク電流が抑えられる。したがって、放電装置１００は、リーク電流を抑えつつ、放出するイオンを増やすことができる。 If the tip of the discharge electrode 30 is protruded from the opening 66, it is possible to increase the number of ions emitted by discharge. Generally, as the number of ions emitted increases, the charge stored in the opening 66 (the charge at the opening 66) also increases, making it easier for leakage current to occur. However, by forming multiple folded portions 50 at the opening 66, leakage current can be suppressed. Therefore, the discharge device 100 can increase the number of ions emitted while suppressing leakage current.
　カバー６５は、着脱式のピース９０を有する。着脱式のピース９０は、開口部６６が形成されている。図４及び図５に示される開口部６６は、着脱式のピース９０が取り外されることで、図６に示されるように、より大きな開口部９６となる。 The cover 65 has a removable piece 90. The removable piece 90 has an opening 66 formed therein. When the removable piece 90 is removed, the opening 66 shown in Figures 4 and 5 becomes a larger opening 96 as shown in Figure 6.
　以下、図６に示される放電装置１００を、実施形態２の変形例として説明する。 Below, the discharge device 100 shown in FIG. 6 will be described as a modified version of embodiment 2.
　図６に示されるように、開口部９６に形成された複数の折返部５０の所定方向２０（－Ｚ方向）は、放電電極３０からコネクタ７０への方向（Ｘ方向）と直交する。具体的に説明すると、複数の折返部５０の所定方向２０は、カバー６５からケース６１への方向（－Ｚ方向）である。 As shown in FIG. 6, the predetermined direction 20 (-Z direction) of the multiple folded portions 50 formed in the opening 96 is perpendicular to the direction (X direction) from the discharge electrode 30 to the connector 70. More specifically, the predetermined direction 20 of the multiple folded portions 50 is the direction (-Z direction) from the cover 65 to the case 61.
　複数の折返部５０の所定方向２０がカバー６５からケース６１への方向（－Ｚ方向）であることにより、開口部６６を±Ｙ方向に大きくすることが可能である。したがって、放電電極３０から開口部６６の縁までが遠くなる。結果として、ケース６１（開口部６６の縁）の帯電によるリーク電流を一層抑えることができる。 Since the predetermined direction 20 of the multiple folded parts 50 is the direction from the cover 65 to the case 61 (-Z direction), it is possible to enlarge the opening 66 in the ±Y direction. Therefore, the distance from the discharge electrode 30 to the edge of the opening 66 is increased. As a result, leakage current caused by charging the case 61 (edge of the opening 66) can be further suppressed.
　ところで、実施形態２の放電装置１００は、保護枠６７を有しない状態で図示されたが、実施形態１と同様に、図１～３に示される保護枠６７を有してもよい。以下、図１を参照して、保護枠６７について詳細に説明する。 The discharge device 100 of the second embodiment is illustrated without the protective frame 67, but like the first embodiment, it may have the protective frame 67 shown in Figs. 1 to 3. The protective frame 67 will be described in detail below with reference to Fig. 1.
　図１に示されるように、カバー６５は、保護枠６７を有する。保護枠６７は、放電電極３０，３５の先端を保護することができる。 As shown in FIG. 1, the cover 65 has a protective frame 67. The protective frame 67 can protect the tips of the discharge electrodes 30 and 35.
　具体的に説明すると、カバー６５は、放電電極３０，３５ごとに保護枠６７を有する。保護枠６７における複数の大通気口６８は、±Ｙ方向に開口する。保護枠６７における複数の小通気口６９は、±Ｘ方向に開口する。大通気口６８及び小通気口６９の配置は、図１に示される例に限定されず、保護枠６７への風が放電電極３０，３５に導かれて保護枠６７から出る配置であればよい。 Specifically, the cover 65 has a protective frame 67 for each discharge electrode 30, 35. A plurality of large ventilation holes 68 in the protective frame 67 open in the ±Y direction. A plurality of small ventilation holes 69 in the protective frame 67 open in the ±X direction. The arrangement of the large ventilation holes 68 and small ventilation holes 69 is not limited to the example shown in Figure 1, and may be arranged so that the wind to the protective frame 67 is guided to the discharge electrodes 30, 35 and exits from the protective frame 67.
　以下、図７及び図８を参照して、放電装置１００を備える空気調和機１１０を説明する。 Below, the air conditioner 110 equipped with the discharge device 100 will be described with reference to Figures 7 and 8.
　図７は、放電装置１００を備える空気調和機１１０の斜視図である。図８は、空気調和機１１０に配置された放電装置１００の斜視図である。 FIG. 7 is a perspective view of an air conditioner 110 equipped with a discharge device 100. FIG. 8 is a perspective view of the discharge device 100 arranged in the air conditioner 110.
　図７に示されるように、空気調和機１１０は、エアコン１１０、空気清浄機、加湿器、又は、除湿器である。図７は、空気調和機１１０がエアコン１１０である例を示す。 As shown in FIG. 7, the air conditioner 110 is an air conditioner 110, an air purifier, a humidifier, or a dehumidifier. FIG. 7 shows an example in which the air conditioner 110 is an air conditioner 110.
　図７に示されるように、エアコン１１０は、放電装置１００と、電圧印加部１０１と、送風部１０２とを備える。放電装置１００は、実施形態１又は２の放電装置１００である。電圧印加部１０１は、放電装置１００のコネクタ７０に電圧を印加する。送風部１０２は、例えばシロッコファンであり、風Ｗを送る。 As shown in FIG. 7, the air conditioner 110 includes a discharge device 100, a voltage application unit 101, and a blower unit 102. The discharge device 100 is the discharge device 100 of embodiment 1 or 2. The voltage application unit 101 applies a voltage to the connector 70 of the discharge device 100. The blower unit 102 is, for example, a sirocco fan, and blows wind W.
　エアコン１１０は、熱交換フィン１０３と、室内側ドレンパン１０４と、壁側ドレンパン１０５と、上下風向ルーバー１０６と、湾曲板１０７とをさらに備える。熱交換フィン１０３は、送風部１０２を室内側、上部及び壁側から囲うように配置される。室内側ドレンパン１０４は、熱交換フィン１０３の室内側における下方に配置される。壁側ドレンパン１０５は、熱交換フィン１０３の壁側における下方に配置される。湾曲板１０７は、送風部１０２を壁側及び下方から囲うように配置される。上下風向ルーバー１０６は、室内側ドレンパン１０４の下方に配置される。室内側ドレンパン１０４と湾曲板１０７との間から、送風部１０２からの風Ｗが、上下風向ルーバー１０６に案内されて、室内に送られる。 The air conditioner 110 further includes a heat exchange fin 103, an indoor drain pan 104, a wall-side drain pan 105, up-down airflow louvers 106, and a curved plate 107. The heat exchange fin 103 is arranged so as to surround the blower section 102 from the indoor side, the top, and the wall side. The indoor drain pan 104 is arranged below the indoor side of the heat exchange fin 103. The wall-side drain pan 105 is arranged below the wall side of the heat exchange fin 103. The curved plate 107 is arranged so as to surround the blower section 102 from the wall side and below. The up-down airflow louvers 106 are arranged below the indoor drain pan 104. The wind W from the blower section 102 is guided by the up-down airflow louvers 106 between the indoor drain pan 104 and the curved plate 107 and sent into the room.
　放電装置１００は、室内側ドレンパン１０４と湾曲板１０７との間で、エアコン１１０の室内側ドレンパン１０４側に配置される。図８に示されるように、放電装置１００は、送風部１０２からの風Ｗが保護枠６７を通過する向きに配置される。風Ｗが保護枠６７を通過するとは、保護枠６７への風Ｗが放電電極３０，３５まで導かれて保護枠６７から出る状態である。具体的には、保護枠６７に形成された一方の大通気口６８から入った風Ｗが、放電電極３０，３５に至った後、保護枠６７に形成された他方の大通気口６８から出る状態である。 The discharge device 100 is disposed on the indoor drain pan 104 side of the air conditioner 110, between the indoor drain pan 104 and the curved plate 107. As shown in FIG. 8, the discharge device 100 is disposed in a direction such that the wind W from the blower 102 passes through the protective frame 67. The wind W passing through the protective frame 67 refers to a state in which the wind W to the protective frame 67 is guided to the discharge electrodes 30, 35 and exits from the protective frame 67. Specifically, this refers to a state in which the wind W that enters from one of the large air vents 68 formed in the protective frame 67 exits from the other large air vent 68 formed in the protective frame 67 after reaching the discharge electrodes 30, 35.
　風Ｗが保護枠６７を通過する向きに放電装置１００が配置されることで、エアコン１１０は、リーク電流を抑えつつ、室内への風Ｗにイオンを十分に含ませることができる。 By positioning the discharge device 100 so that the wind W passes through the protective frame 67, the air conditioner 110 can ensure that the wind W entering the room contains sufficient ions while suppressing leakage current.
