Description

オゾン発生装置Ozone generator
　本発明は、第１の電極と第２の電極との間で放電を起こすことによってオゾンを発生させるオゾン発生装置に関する。 The present invention relates to an ozone generator that generates ozone by causing a discharge between a first electrode and a second electrode.
　一般的に、オゾン発生装置は、誘電体で覆われた第１の電極及び第２の電極をそれぞれ対向させ、第１の電極と第２の電極との間に高電圧を印加することにより、第１の電極と第２の電極との間で放電（無声放電）を起こし、オゾンを発生させる。 In general, an ozone generator is configured such that a first electrode and a second electrode covered with a dielectric are opposed to each other, and a high voltage is applied between the first electrode and the second electrode, A discharge (silent discharge) is caused between the first electrode and the second electrode to generate ozone.
　この種のオゾン発生装置として、板状の第１の電極及び第２の電極を相対的にスライドさせる技術が知られている（特許文献１参照）。この技術によれば、第１の電極と第２の電極との間で放電が起こる空間の体積、すなわち、第１の電極と第２の電極とが対向する表面積を変更することによって、オゾンの発生量を容易に調整できる。 As this type of ozone generator, a technology of relatively sliding a plate-like first electrode and a second electrode is known (see Patent Document 1). According to this technique, by changing the volume of the space in which discharge occurs between the first electrode and the second electrode, that is, the surface area where the first electrode and the second electrode face each other, The amount generated can be easily adjusted.
日本国特開２００１－１１０５４９号公報(JP 2001-110549 A)Japanese Laid-Open Patent Publication No. 2001-110549 (JP 2001-110549 A)
　しかしながら、上述した従来のオゾン発生装置では、第１の電極及び第２の電極が一定の領域（第１の領域）で長時間放電された場合、第１の電極及び第２の電極のそれぞれの表面において放電部と非放電部とが形成されてしまう。このため、放電部と非放電部とによって第１の電極及び第２の電極のそれぞれの表面上にムラが生じてしまう。 However, in the conventional ozone generator described above, when the first electrode and the second electrode are discharged for a long time in a certain region (first region), each of the first electrode and the second electrode A discharge portion and a non-discharge portion are formed on the surface. For this reason, the discharge part and the non-discharge part cause unevenness on the surfaces of the first electrode and the second electrode.
　そして、オゾンの発生量を変更するために、第１の電極及び第２の電極の放電領域を上記第１の領域から他の領域へ変更した場合、表面にムラが生じた第１の電極及び第２の電極との間で放電が起こり、偏った放電（偏放電）が生じてしまう。従って、従来のオゾン発生装置では、オゾンの発生量を容易に調整できるものの、オゾンの発生量が安定しないという問題があった。 Then, when the discharge region of the first electrode and the second electrode is changed from the first region to another region in order to change the amount of ozone generated, the first electrode having unevenness on the surface and Discharge occurs between the second electrode and uneven discharge (biased discharge) occurs.

The second electrode 20 is connected to the high-voltage power supply 40 by a conducting wire 7. The second electrode 20 is provided at a predetermined distance (arbitrary interval) from the first electrode 10. The second electrode 20 is formed in a disc shape and is provided concentrically with the first electrode 10.

As described above, any one of the large electrode member 11, the middle electrode member 12, and the small electrode member 13 is brought close to the second electrode 20 by the electrode member changing device 30.
　電極部材変更装置３０は、大電極部材１１、中電極部材１２及び小電極部材１３のいずれを第２の電極２０に近づけるように構成される。電極部材変更装置３０は、第１支持体３１と、第２支持体３２と、歯車３３と、減速装置３４と、モータ３５とによって構成される。 The electrode member changing device 30 is configured to bring any one of the large electrode member 11, the middle electrode member 12, and the small electrode member 13 closer to the second electrode 20. The electrode member changing device 30 includes a first support 31, a second support 32, a gear 33, a speed reduction device 34, and a motor 35.
　第１支持体３１は、小電極部材１３を支持する。また、第１支持体３１の一方の面には、歯車３３が噛合する歯部が形成される。第１支持体３１には、歯車３３を介して第２支持体３２が対向する。この第２支持体３２は、大電極部材１１を支持する。第２支持体３２の一方の面には、歯車３３が噛合する歯部が形成される。 The first support 31 supports the small electrode member 13.

Specifically, the gear 33 meshes with the teeth of the first support 31 and the teeth of the second support 32. The gear 33 is connected to a reduction gear 34 that can reduce the rotation of the gear 33.
　減速装置３４は、モータ３５に接続される。具体的には、減速装置３４は、図２（ａ）に示すように、モータ３５の軸心に連結される大歯車３４Ａと、大歯車３４Ａに噛合するとともに歯車３３と同軸に連結される小歯車３４Ｂとによって構成される。 The reduction gear 34 is connected to the motor 35.

And a gear 34B.
　なお、減速装置３４は、必ずしも大歯車３４Ａと小歯車３４Ｂとによって構成される必要はない。例えば、図２（ｂ）に示すように、減速装置３４は、モータ３５の軸心に連結される大ドラム３４Ｃと、歯車３３と同軸に連結される小ドラム３４Ｄと、大ドラム３４Ｃと小ドラム３４Ｄとの外周に巻きつけられる平ベルト３４Ｅとによって構成されていてもよい。 Note that the reduction gear 34 does not necessarily have to be constituted by the large gear 34A and the small gear 34B. For example, as shown in FIG. 2B, the speed reducer 34 includes a large drum 34C coupled to the shaft center of the motor 35, a small drum 34D coupled coaxially with the gear 33, a large drum 34C and a small drum.

（１－２）オゾン発生装置１００の動作
　高圧電源４０のスイッチがＯＮになると、導線５を介して第１の電極１０に電流が流れるとともに、導線7を介してと第２の電極２０に電流が流れる。そして、第１の電極１０及び第２の電極２０に高電圧を印加されることによって、第１の電極１０と第２の電極２０との間で放電が起こる。第１の電極１０と第２の電極２０との間で放電が起こると、高いエネルギーを持つ電子と気体中の酸素分子が衝突し、オゾンが生成される。なお、オゾンの発生量は、第２の電極２０と放電を起こす第１の電極１０の部材が、大電極部材１１、中電極部材１２及び小電極部材１３かによって可変し、大電極部材１１のように太い方がオゾンの発生量が多くなる。 (1-2) Operation of the ozone generator 100 When the switch of the high-voltage power supply 40 is turned on, a current flows to the first electrode 10 through the conductor 5, and a current to the second electrode 20 through the conductor 7. Flows. Then, when a high voltage is applied to the first electrode 10 and the second electrode 20, a discharge occurs between the first electrode 10 and the second electrode 20. When a discharge occurs between the first electrode 10 and the second electrode 20, electrons having high energy collide with oxygen molecules in the gas, and ozone is generated. Note that the amount of ozone generated varies depending on whether the member of the first electrode 10 that causes discharge with the second electrode 20 is the large electrode member 11, the middle electrode member 12, and the small electrode member 13. As the thickness increases, the amount of ozone generated increases.
　図３（ａ）に示すように、通常時として、中電極部材１２が第２の電極２０の中心位置に最も近づいている状態にすることにより、中電極部材１２と第２の電極２０との間で放電が起こる。 As shown in FIG. 3A, as a normal condition, the middle electrode member 12 is closest to the center position of the second electrode 20, so that the middle electrode member 12 and the second electrode 20 are Discharge occurs between them.
　また、オゾンの発生量を下げる場合、すなわち使用者が操作部６０からオゾンの発生量を下げるように操作した場合、この情報を含む信号が制御部５０へ送られ、モータ３５が作動することによって、歯車３３が時計回り方向へ回転する。これにより、歯車３３を介して第１支持体３１が第２の電極２０側（図面では上方）に移動し、第２支持体３２が第２の電極２０から離れる方向（図面では下方）に移動する。そして、図３（ｂ）に示すように、小電極部材１３が第２の電極２０の中心位置に最も近づいている状態で、モータ３５の回転が停止し、小電極部材１３と第２の電極２０との間で放電を起こすことが可能となる。 Further, when the amount of generated ozone is decreased, that is, when the user operates the operation unit 60 to decrease the amount of generated ozone, a signal including this information is sent to the control unit 50 and the motor 35 is activated. The gear 33 rotates in the clockwise direction. As a result, the first support 31 moves to the second electrode 20 side (upward in the drawing) via the gear 33, and the second support 32 moves in the direction away from the second electrode 20 (downward in the drawing). To do. Then, as shown in FIG. 3B, in a state where the small electrode member 13 is closest to the center position of the second electrode 20, the rotation of the motor 35 is stopped, and the small electrode member 13 and the second electrode are stopped. It is possible to cause a discharge with 20.
　一方、オゾンの発生量を上げる場合、すなわち使用者が操作部６０からオゾンの発生量を上げるように操作した場合、この情報を含む信号が制御部５０へ送られ、モータ３５が作動することによって、歯車３３が反時計回り方向へ回転する。そして、図３（ｃ）に示すように、大電極部材１１が第２の電極２０の中心位置に最も近づいている状態で、モータ３５の回転が停止し、大電極部材１１と第２の電極２０との間で放電を起こすことが可能となる。 On the other hand, when the ozone generation amount is increased, that is, when the user operates the operation unit 60 to increase the ozone generation amount, a signal including this information is sent to the control unit 50 and the motor 35 is activated. The gear 33 rotates counterclockwise. Then, as shown in FIG. 3C, the rotation of the motor 35 is stopped in a state where the large electrode member 11 is closest to the center position of the second electrode 20, and the large electrode member 11 and the second electrode are stopped. It is possible to cause a discharge with 20.
（１－３）作用・効果
　以上説明した第１実施形態では、第２の電極２０は、第１の電極１０の部材のうち、大電極部材１１、中電極部材１２及び小電極部材１３のいずれか一つと放電する。これにより、オゾンの発生量を変更する場合、異なる放電領域で放電できる、すなわち、第２の電極２０との間で放電する第１の電極１０の部材（大電極部材１１、中電極部材１２及び小電極部材１３）そのものを変更できる。このため、例えば、通常時として、中電極部材１２と第２の電極２０との間で長時間放電されても、従来のように中電極部材１２に放電部と非放電部とが形成されることがない。従って、偏った放電（偏放電）が生じることを抑制でき、オゾンの発生量を確実に安定させることができる。また、第２の電極２０との間で放電する部材（大電極部材１１、中電極部材１２及び小電極部材１３）を変えるのみで、オゾンの発生量を容易に調整できる。 (1-3) Actions / Effects In the first embodiment described above, the second electrode 20 is any one of the members of the first electrode 10, which are the large electrode member 11, the middle electrode member 12, and the small electrode member 13. Discharge with one. Thereby, when changing the generation amount of ozone, it is possible to discharge in different discharge regions, that is, the members of the first electrode 10 (the large electrode member 11, the middle electrode member 12, and the second electrode 20). The small electrode member 13) itself can be changed. For this reason, for example, even if a normal discharge occurs between the intermediate electrode member 12 and the second electrode 20 for a long time, a discharge portion and a non-discharge portion are formed in the intermediate electrode member 12 as in the conventional case. There is nothing. Therefore, it is possible to suppress the occurrence of uneven discharge (partial discharge) and to reliably stabilize the amount of ozone generated. In addition, the amount of ozone generated can be easily adjusted only by changing the members (large electrode member 11, middle electrode member 12, and small electrode member 13) that discharge with the second electrode 20.
　第１実施形態では、大電極部材１１、中電極部材１２及び小電極部材１３は、それぞれ円筒状に形成される。これにより、外周面が平坦状であるため、角柱と比べてオゾンの発生量をさらに安定させることができる。 In the first embodiment, the large electrode member 11, the middle electrode member 12, and the small electrode member 13 are each formed in a cylindrical shape. Thereby, since the outer peripheral surface is flat, the generation amount of ozone can be further stabilized as compared with the prism.
　第１実施形態では、オゾン発生装置１００は、大電極部材１１、中電極部材１２及び小電極部材１３のいずれか一つを第２の電極２０に近づける電極部材変更装置３０を備える。これにより、第２の電極２０との間で放電する部材（大電極部材１１、中電極部材１２及び小電極部材１３）を容易に変更することができる。従って、オゾンの発生量をさらに容易に調整できる。 In the first embodiment, the ozone generator 100 includes an electrode member changing device 30 that brings any one of the large electrode member 11, the middle electrode member 12, and the small electrode member 13 close to the second electrode 20. Thereby, the member (the large electrode member 11, the middle electrode member 12, and the small electrode member 13) which discharges between the 2nd electrodes 20 can be changed easily. Therefore, the amount of ozone generated can be adjusted more easily.
　第１実施形態では、大電極部材１１内に中電極部材１２が設けられ、中電極部材１２内に小電極部材１３が設けられる。このため、大電極部材１１、中電極部材１２及び小電極部材１３がそれぞれ異なる位置に設けられる場合と比較して、省スペース化を実現できる。 In the first embodiment, the middle electrode member 12 is provided in the large electrode member 11, and the small electrode member 13 is provided in the middle electrode member 12. For this reason, space saving is realizable compared with the case where the large electrode member 11, the medium electrode member 12, and the small electrode member 13 are provided in a respectively different position.
　第１実施形態では、第１の電極１０と第２の電極２０とは、同心円上に設けられる。これにより、第２の電極２０との間で放電する部材の位置決めが不要となる。従って、オゾンの発生量をさらに容易に調整できるとともに、位置決めする機構を設ける必要がない。このため、製造コストの低減に寄与する。 In the first embodiment, the first electrode 10 and the second electrode 20 are provided on concentric circles. Thereby, positioning of the member discharged between the 2nd electrode 20 becomes unnecessary. Therefore, the amount of ozone generated can be adjusted more easily, and there is no need to provide a positioning mechanism. For this reason, it contributes to the reduction of manufacturing cost.

　第２実施形態に係るオゾン発生装置２００について、図４～６を参照しながら説明する。なお、上述した第１実施形態に係るオゾン発生装置１００と同一部分には同一の符号を付して、相違する部分を主として説明する。 (2) Second Embodiment An ozone generator 200 according to a second embodiment will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the same part as the ozone generator 100 which concerns on 1st Embodiment mentioned above, and a different part is mainly demonstrated.
　上述した第１実施形態に係るオゾン発生装置１００では、大電極部材１１内に中電極部材１２が設けられ、中電極部材１２内に小電極部材１３が設けられる。これに対して、第２実施形態に係るオゾン発生装置２００では、大電極部材１１、中電極部材１２及び小電極部材１３は、それぞれ異なる位置に設けられる。なお、第２実施形態に係るオゾン発生装置２００は、第１実施形態で説明した制御部５０及び操作部６０を備えていない。 In the ozone generator 100 according to the first embodiment described above, the middle electrode member 12 is provided in the large electrode member 11, and the small electrode member 13 is provided in the middle electrode member 12.
