この考案は、自動車の空調装置等に用いられる空気清浄装置に関する。 The present invention relates to an air cleaning device used for an air conditioner of an automobile.
【０００２】[0002]
従来、例えば、実開昭６２−５６１５３号公報に示されるように、塵埃をプラ スに帯電させる荷電部（アイオナイザ）を配し、その下流にマイナスに帯電した 集塵部（コレクタ）を配し、２段式による集塵装置を形成して塵埃を電気的に捕 集していた。また、実開昭６２−１６０２２３号公報に示されるように、荷電部 と集塵部を上流側と下流側と位置を隔てずに、荷電部の電極と集塵部の電極を上 下に交互に積層することにより一か所に配置して、小型化を図ったものがある。 そして、荷電部と集塵部とが上下に交互に積層されている電極には、アルミニウ ム等の導電性金属板を使用すると共に、荷電部の電極が放電するための放電対向 電極に円状透孔を形成した金属平板を使用して構成されており、それらに直流の 高電圧をかけて塵埃を捕集する形態をとっている。 Conventionally, for example, as disclosed in Japanese Utility Model Laid-Open No. 62-56153, a charging portion (ionizer) for charging dust to a plus is arranged, and a dust collecting portion (collector) charged to a minus is arranged downstream thereof. A two-stage type dust collector was formed to electrically collect dust. In addition, as disclosed in Japanese Utility Model Laid-Open No. 62-160223, the charging section electrode and the dust collecting section are not separated from the upstream side and the downstream side, and the charging section electrode and the dust collecting section electrode are alternately turned up and down. Some of them are placed in one place by stacking them on one another to reduce the size. A conductive metal plate such as aluminum is used for the electrode in which the charging part and the dust collecting part are alternately stacked one above the other, and a circular electrode is used as the discharge counter electrode for the electrode of the charging part to discharge. It is constructed by using metal flat plates with through holes, and takes the form of collecting dust by applying a high DC voltage to them.
【０００３】[0003]
ところで、近年の自動車における空気清浄装置が占める割合は、エンジンの高 性能化に伴って機能が付加されたり、エアバック等の安全装置の組み込み等によ り減少する傾向にある。したがって、前者の従来技術のように、荷電部と集塵部 とを独立させて二カ所配備式の集塵装置が装備された空気清浄装置では、場所を 取るために大型車なら良いが、小型車には専有空間を確保するのに厳しいという 問題点があった。 By the way, the percentage of air purifying devices in automobiles in recent years tends to decrease due to the addition of functions as the performance of engines increases and the incorporation of safety devices such as airbags. Therefore, as in the former prior art, an air purifier equipped with a dust collector with two separate locations for the charging part and the dust collecting part is good for large vehicles to save space, but for small vehicles. Had a problem that it was difficult to secure a private space.
【０００４】 また、後者の従来技術においては、アルミニウム等の導電性金属板を用いて形 成された荷電部の電極及び集塵部の電極が、異なる電極ではあるが交互に積層さ れて構成されているために隣合わせの電極間でリークする危険があるという問題 点がある。また放電対向電極が金属平板に円状透孔を形成して構成されているの で、空気の通気抵抗が大きくなり必要風量及び圧力が得れず、車室内に不快感が 生じることがあると共に、塵埃を帯電するためのコロナ放電が限られた範囲とな るため捕集効率に難点が見られた。In the latter prior art, the electrodes of the charging part and the electrodes of the dust collecting part, which are formed by using a conductive metal plate such as aluminum, are different electrodes, but are alternately laminated. Therefore, there is a problem that there is a risk of leaking between adjacent electrodes. Further, since the discharge counter electrode is formed by forming the circular through hole on the metal flat plate, the ventilation resistance of air becomes large, the required air volume and pressure cannot be obtained, and uncomfortable feeling may occur in the passenger compartment. There was a problem in the collection efficiency because the corona discharge for charging dust was in a limited range.
【０００５】 このために、この考案は、大型車に限らず小型車にも搭載可能とし、電極間で のリークの危険性の少ない集塵装置を有すると共に、風量不足による不快感をな くし、塵埃捕集効率の高い空気清浄装置を提供することにある。For this reason, the present invention can be mounted not only on a large vehicle but also on a small vehicle, has a dust collector with a low risk of leakage between electrodes, eliminates discomfort due to insufficient air flow, and reduces dust. An object of the present invention is to provide an air cleaning device having high collection efficiency.
【０００６】[0006]
しかして、この考案は、空調ダクト内に直流電源を介して接続された放電電極 とこの放電電極に対向する集塵電極とを交互に配置し、導電体により形成された メッシュ状の放電対向電極を前記放電電極より上流側に配置し、この放電対向電 極は、前記直流電源の前記放電電極が接続された極と反対側の極に接続されてお り、前記放電電極及び集塵電極は絶縁部材に導電性部材を設けて構成され、前記 放電電極の導電性部材は、前記集塵電極の絶縁部材と対峙していることにある。 In this invention, therefore, a discharge electrode connected via a DC power source in the air conditioning duct and a dust collection electrode facing the discharge electrode are alternately arranged, and a mesh-shaped discharge counter electrode formed of a conductor is formed. Is arranged on the upstream side of the discharge electrode, and the discharge opposite electrode is connected to a pole on the opposite side of the pole to which the discharge electrode of the DC power source is connected, and the discharge electrode and the dust collecting electrode are The insulating member is provided with a conductive member, and the conductive member of the discharge electrode faces the insulating member of the dust collecting electrode.
【０００７】[0007]
したがって、この考案においては、集塵装置を構成する交互に積層された荷電 部の電極と集塵部の電極にプラスチックフィルムの素材を使用し、それらの電極 の片面に導電性部材を設けたので、荷電部と集塵部の二か所配備から一か所で多 層配備が行えることは勿論であり、隣極間でのリークがないので、隣極間を狭め ることができるため、小型化が可能となる。また、放電電極より上流に導電体金 属により形成された放電対向電極をメッシュ状にしたため、風圧を下げることな く広範囲での塵埃の帯電が行えるので、不快感を防ぎ、捕集効率を高くでき、上 記課題が達成できるものである。 Therefore, in the present invention, the material of the plastic film is used for the electrodes of the charging part and the electrodes of the dust collecting part which are alternately laminated to constitute the dust collecting device, and the conductive member is provided on one side of these electrodes. Of course, it is possible to perform multi-layer deployment in one place from two places of charging part and dust collecting part, and since there is no leak between adjacent poles, it is possible to narrow between adjacent poles, so it is compact. Can be realized. In addition, since the discharge counter electrode, which is made of conductive metal upstream from the discharge electrode, has a mesh shape, dust can be charged in a wide range without lowering the wind pressure, preventing discomfort and increasing collection efficiency. Yes, the above tasks can be achieved.

以下、この考案の実施例について図面により説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【０００９】 図１に示す自動車用空気調和装置１は、送風部２と、冷却部３と、温調部４と を接合して基本的に構成されている。The automobile air conditioner 1 shown in FIG. 1 is basically configured by joining a blower unit 2, a cooling unit 3, and a temperature control unit 4.
【００１０】 送風部２は、外気吸入口５と内気吸入口６とを有し、インテーク切替ドア７で 選択導入された吸入口からの空気をモータ８で駆動されるファン９で下流側に送 風するようになっている。The blower unit 2 has an outside air intake port 5 and an inside air intake port 6, and sends air from the intake port selectively introduced by the intake switching door 7 to a downstream side by a fan 9 driven by a motor 8. It is supposed to wind.
【００１１】 冷却部３は、冷房サイクルを構成するエバポレータ（熱交換器）１１を配して 基本的に構成され、送風部２からの送風空気を冷却する。The cooling unit 3 is basically configured by arranging an evaporator (heat exchanger) 11 that constitutes a cooling cycle, and cools the blown air from the blower unit 2.
【００１２】 温調部４は、ヒータコア１２とエアミックスドア１３とを有して基本的の構成 され、エアミックスドア１３の開度を適宜に調節することで、冷却部３からの冷 却空気をヒータコア１２を通過させて加熱するものと、ヒータコア１２を単にバ イパスさせるものとに分流し、この分流した空気を下流側のエアミックス室１４ で混合し、温調空気を所望される温度に調節する。そしてこの温調された空気は 、各モードドア１５，１６，１７を介して選択開放された各吹出口１８，１９， ２０から図示されない車室内に吹き出されるようになっている。The temperature control unit 4 has a basic configuration including a heater core 12 and an air mix door 13. By appropriately adjusting the opening of the air mix door 13, the cooling air from the cooling unit 3 is cooled. Is passed through the heater core 12 to be heated and the heater core 12 is simply bypassed, and the split air is mixed in the downstream air mix chamber 14 to bring the temperature-controlled air to a desired temperature. Adjust. Then, the temperature-controlled air is blown out into the vehicle interior (not shown) from the respective outlets 18, 19 and 20 that are selectively opened via the mode doors 15, 16 and 17.
【００１３】 また、ファン９の下流側には、メッシュ状の導電体で形成された放電対向電極 １０が設けられ、この放電対向電極１０より下流側で、且つエバポレータ１１よ りも上流側には、下記する積層電極群２５が配されている。Further, a discharge counter electrode 10 formed of a mesh-shaped conductor is provided on the downstream side of the fan 9, and on the downstream side of the discharge counter electrode 10 and on the upstream side of the evaporator 11. The following laminated electrode group 25 is arranged.
【００１４】 この積層電極群２５は、放電電極２６と集塵電極２７とを所定の間隔を開けて 交互に複数段積層配置して構成されて、積層方向が通風方向に対して直角になっ ている。The laminated electrode group 25 is configured by alternately arranging a plurality of discharge electrodes 26 and dust collecting electrodes 27 at predetermined intervals so as to be laminated, and the laminating direction is perpendicular to the ventilation direction. There is.
【００１５】 積層電極群２５の放電電極２６は、５〜７ＫＶの直流高電圧電源２８の正極側 に接続され、集塵電極２７は直流高電圧電源２８の負極側に接続されている。The discharge electrode 26 of the stacked electrode group 25 is connected to the positive electrode side of the DC high voltage power supply 28 of 5 to 7 KV, and the dust collecting electrode 27 is connected to the negative electrode side of the DC high voltage power supply 28.
【００１６】 放電電極２６は、プラスチックフィルム等の絶縁部材２６ｂに導電体２６ａで ある例えばアルミ金属箔を片面に塗布して形成したものである。アルミ金属箔が 塗布された片面側先端は、放電対向電極１０に向かって尖頭形状に成形され、尖 頭部分は、放電対向電極１０側に突出してより接近するようにして形成されてい る。そして、放電電極２６と放電対向電極１０との距離は、放電電極１０の尖頭 部分からの放電が放電対向電極１０の全面に行き届く範囲でできるだけ小さく設 定されている。The discharge electrode 26 is formed by coating an insulating member 26b such as a plastic film with a conductor 26a such as an aluminum metal foil on one surface. The one-sided tip coated with the aluminum metal foil is formed in a pointed shape toward the discharge counter electrode 10, and the pointed portion is formed so as to project toward the discharge counter electrode 10 side and be closer to the discharge counter electrode 10. The distance between the discharge electrode 26 and the discharge counter electrode 10 is set to be as small as possible within the range in which the discharge from the tip of the discharge electrode 10 reaches the entire surface of the discharge counter electrode 10.
【００１７】 前記放電対向電極１０は、荒いゴミを除去するフィルタの役目を果たすと共に 、前記放電電極２６の放電の相手極と成るため放電電極２６と反対の電極となる よう直流高電圧電源２８の負極側に大地を介して接続されている。The discharge counter electrode 10 plays a role of a filter for removing rough dust, and serves as a counter electrode of the discharge electrode 26 for discharging, so that the discharge counter electrode 10 is an electrode opposite to the discharge electrode 26. It is connected to the negative electrode side through the ground.
【００１８】 また、集塵電極２７も、プラスッチックフィルム等の絶縁部材２７ｂに導電体 ２７ａである例えばアルミ金属箔を片面に塗布して形成されている。The dust collecting electrode 27 is also formed by coating an insulating member 27b such as a plastic film with a conductor 27a such as an aluminum metal foil on one surface.
【００１９】 そして、放電電極２６と集塵電極２７が交互に複数段積層配置されて成る積層 電極群２５においては、放電電極２６の導電体２６ａが集塵電極２７の絶縁部材 ２７ｂ（あるいは、放電電極２６の絶縁部材２６ｂが集塵電極２７の導電体２７ ａ）に対峙するように絶縁部材２６ｂ，２７ｂと導電体２７ａ，２６ａとが異極 間で常に向かい合う構成となっている。In the laminated electrode group 25 in which the discharge electrodes 26 and the dust collecting electrodes 27 are alternately laminated in a plurality of layers, the conductors 26 a of the discharge electrodes 26 are the insulating members 27 b (or the discharge electrodes of the dust collecting electrodes 27). The insulating members 26b, 27b and the conductors 27a, 26a are always opposed to each other in different poles so that the insulating member 26b of the electrode 26 faces the conductor 27a) of the dust collecting electrode 27.
【００２０】 図２に示すように、特にこの実施例においては、放電電極２６と集塵電極２７ とのピッチｌ2 が、１０ｍｍ程度となっており、集塵装置として通風方向に必要 な長さ、即ち、放電対向電極１０から放電電極２６の下流側端までの長さｌ1 が 、５０ｍｍ以下となっている。また、放電電極自体の通風方向の長さｌ3 は、２ ０ｍｍ位となっている。As shown in FIG. 2, particularly in this embodiment, the pitch l 2 between the discharge electrode 26 and the dust collecting electrode 27 is about 10 mm, which is the length required in the ventilation direction as the dust collecting device. That is, the length l 1 from the discharge counter electrode 10 to the downstream end of the discharge electrode 26 is 50 mm or less. Further, the length l 3 of the discharge electrode itself in the ventilation direction is about 20 mm.
【００２１】 このように、構成された自動車用空気調和装置１において、直流高電圧電源２ ８より電圧が印加されると放電電極２６はプラスに帯電し、放電対向電極１０は マイナスに帯電する。そのことにより両電極間に、コロナ放電が発生する。In the air conditioner 1 for an automobile thus constructed, the discharge electrode 26 is positively charged and the discharge counter electrode 10 is negatively charged when a voltage is applied from the DC high voltage power supply 28. As a result, corona discharge occurs between both electrodes.
【００２２】 このため、ファン９の回転によって送風されてきた空気は、放電対向電極１０ を通過するわけであるが、荒いゴミはそこで除去され、塵埃はメッシュ状の網目 を通過する際に、放電対向電極１０と放電電極２６間でおきるコロナ放電によっ て放電電極２６側と同じプラスの極性に帯電される。Therefore, the air blown by the rotation of the fan 9 passes through the discharge counter electrode 10, but the coarse dust is removed there, and the dust is discharged when passing through the mesh mesh. Corona discharge between the counter electrode 10 and the discharge electrode 26 charges the same positive polarity as the discharge electrode 26 side.
【００２３】 また、一方、集塵電極２７は、直流高電圧電源２８の負極側に接続されている ので、印加電圧によって放電電極２６との間に電位差が形成され、ファン９の送 風圧によって押し流されるプラスに帯電された塵埃は、マイナスに帯電している 集塵電極２７の方へ移動し、此処において、積層電極群２５を通過しようとする 際に該集塵電極２７に電気的に捕集される。On the other hand, since the dust collecting electrode 27 is connected to the negative electrode side of the DC high voltage power supply 28, a potential difference is formed between the dust collecting electrode 27 and the discharge electrode 26 due to the applied voltage, and the dust is swept away by the blowing pressure of the fan 9. The positively charged dust moves toward the negatively charged dust collecting electrode 27, where it is electrically collected by the dust collecting electrode 27 as it passes through the laminated electrode group 25. To be done.
【００２４】 尚、本実施例では、集塵電極２７の導電体２７ａの素材にアルミ箔を使用した が、半導体塗料を塗布しても同様の作用効果が得れる。したがって、放電電極２ ６及び集塵電極２７の導電体２６ａ，２７ａは、半導体をも含む広い意味である 。Although aluminum foil is used as the material of the conductor 27a of the dust collecting electrode 27 in this embodiment, the same effect can be obtained by applying a semiconductor paint. Therefore, the conductors 26a and 27a of the discharge electrode 26 and the dust collecting electrode 27 have a broad meaning including semiconductors.
【００２５】[0025]
以上説明したように、この考案においては、メッシュ状の放電対向電極を形成 し、その下流側に放電電極と集塵電極とを交互に対向配置し、放電電極と集塵電 極とを絶縁部材とその片面側に設けられた導電性部材とにより構成し、隣合う電 極間で絶縁部材と導電性部材とを対向させるようにしたので、電極間の抵抗値を 高くすることができ、電極間を狭めても隣同士でリークする危険がなくなり小型 化が可能となる。また、導電体のメッシュ状の放電対向電極を使用したため、コ ロナ放電範囲が大きくなり捕集効率を高めると共に、必要とする風圧を損なう事 もない。 As described above, in the present invention, the discharge counter electrode in the form of a mesh is formed, and the discharge electrode and the dust collecting electrode are alternately arranged on the downstream side, and the discharge electrode and the dust collecting electrode are insulated from each other. And the conductive member provided on one side thereof, and the insulating member and the conductive member are made to face each other between the adjacent electrodes, so that the resistance value between the electrodes can be increased, Even if the space is narrowed, there is no danger of leaks next to each other, and miniaturization is possible. Further, since the mesh-shaped discharge counter electrode of the conductor is used, the corona discharge range is widened, the collection efficiency is improved, and the required wind pressure is not impaired.
