Description

本発明は、静電霧化装置、殊にナノメータサイズの帯電微粒子水（ミスト）を発生させる静電霧化装置を備えた空調装置に関するものである。   The present invention relates to an electrostatic atomizer, and more particularly to an air conditioner including an electrostatic atomizer that generates nanometer-sized charged fine particle water (mist).

水を静電霧化することでナノメータサイズの帯電微粒子水（ミスト）を発生させる静電霧化装置が特許文献１で知られている。これは水が供給される放電電極と対向電極との間に高電圧を印加して放電させ、放電電極が保持している水にレイリー分裂を生じさせて霧化させることによってナノメータサイズの帯電微粒子水（ミスト）を発生させるものであり、このようにして形成されるミストはラジカルを含んでいるとともに長寿命であって、空間内への拡散を大量に行うことができ、室内の壁面や衣服やカーテンなどに付着した悪臭成分などに効果的に作用して無臭化することができるといった特徴を有している。 An electrostatic atomizer that generates nanometer-sized charged fine particle water (mist) by electrostatic atomization of water is known from Patent Document 1. This is because nanometer-sized charged fine particles are produced by applying a high voltage between the discharge electrode to which water is supplied and the counter electrode to discharge, causing Rayleigh splitting in the water held by the discharge electrode, and atomizing. Water (mist) is generated, and the mist thus formed contains radicals and has a long life, and can diffuse a large amount into the space. It has the characteristic that it can act effectively on malodorous components adhering to the curtain or the like and can be made non-brominated.

そして上記ミストは、空調装置の風に乗せることで室内に拡散させることができるが、静電霧化装置を空調装置内に組み込む場合、次の点が問題となる。すなわち、エバポレータやヒータといった機器を備えた空調装置内の送風路上に静電霧化装置を設置すると、空調装置によって調整された高温度の空気及び／又は低湿度の空気に静電霧化装置が晒されることになり、この場合、静電霧化させるために放電電極に供給している水が上記調整された空気によって蒸発してしまい、放電による静電霧化が阻害されてしまう。   And although the said mist can be spread | diffused indoors by putting on the wind of an air conditioner, when incorporating an electrostatic atomizer in an air conditioner, the following points will pose a problem. That is, when an electrostatic atomizer is installed on an air passage in an air conditioner equipped with devices such as an evaporator and a heater, the electrostatic atomizer is applied to high-temperature air and / or low-humidity air adjusted by the air-conditioner. In this case, water supplied to the discharge electrode for electrostatic atomization is evaporated by the adjusted air, and electrostatic atomization due to discharge is inhibited.

特に放電電極を冷却することで空気中の水分を結露させて放電電極上に静電霧化させるための水を生成するようにした静電霧化装置では、水の補給の手間がいらないという点で優れた使い勝手を有するが、このタイプのものでは放電電極上に結露水を生成することすらできない場合が生じてしまう。   In particular, in an electrostatic atomizer that generates water for electrostatic atomization on the discharge electrode by condensing moisture in the air by cooling the discharge electrode, there is no need to supply water. However, with this type, there may be a case where condensed water cannot even be generated on the discharge electrode.

また、車載用の空調装置のように、エバポレータやヒータといった機器と、調整した空気を室内に吹き出す吹き出し口との間をダクトで形成した長い送風路で接続しているものにおいては、上記送風路内で静電霧化によりミストを発生させても、送風路内の温風はかなり高温低湿度であるために、吹き出し口に至るまでに消失してしまって、室内に吐出されるミスト量がきわめて少なくなる。
特許第３２６０１５０号公報 In addition, in the case where a long air passage formed by a duct is connected between a device such as an evaporator or a heater and a blow-out port for blowing out the adjusted air into the room like an in-vehicle air conditioner, the above air passage Even if mist is generated by electrostatic atomization in the inside, the warm air in the air passage is quite hot and low in humidity, so it disappears until it reaches the outlet, and the amount of mist discharged into the room is small. Very little.
Japanese Patent No. 3260150

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、静電霧化によって得たミストを効果的に室内に拡散させることができる静電霧化装置を備えた空調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 provides an air conditioner equipped with an electrostatic atomizer capable of effectively diffusing mist obtained by electrostatic atomization into a room. It is an object to do.

上記課題を解決するために本発明は、高電圧が印加される放電電極と、上記放電電極を冷却して放電電極部分に空気中の水分を基に静電霧化させるための水を生成させる冷却手段と、静電霧化したミストを放出する放出口とを備える静電霧化装置が設けられた空調装置であって、上記静電霧化装置は、高温度の空気または低湿度の空気を供給するエバポレータを具備する空調装置における調整後の空気の吹き出し口の近辺で且つ上記吹き出し口に至る送風路外に配設されているとともに、上記吹き出し口に隣接配置され、吹き出し口から吐出される調整された空気の流れに乗せるミストを放出する放出口と上記吹き出し口とが別体であってほぼ同面に位置し、且つ、上記放出口からのミストの放出方向の延長線と吹き出し口からの風の吐出方向とが交叉していることに特徴を有している。
In order to solve the above problems, the present invention generates a discharge electrode to which a high voltage is applied and water for electrostatically atomizing the discharge electrode portion based on moisture in the air by cooling the discharge electrode. An air conditioner provided with an electrostatic atomizer including a cooling means and an outlet for discharging electrostatic atomized mist, wherein the electrostatic atomizer includes high-temperature air or low-humidity air. together they are arranged outside the air passage to and in the vicinity of the outlet of the air after the adjustment reaches the above outlet of the air conditioning apparatus comprising an evaporator for supplying, disposed adjacent to the outlet, discharged from outlet The outlet for discharging the mist to be put on the adjusted air flow and the outlet are separate and located substantially on the same plane, and the extension line of the mist emission direction from the outlet and the outlet How to discharge wind from Bets are characterized in that they intersect.

送風路外に配置された静電霧化装置での静電霧化によって得たミストは静電霧化装置の放出口から吐出された後、空調装置の吹き出し口からの風に乗って室内に拡散されるようにしたものである。 The mist obtained by electrostatic atomization in the electrostatic atomizer arranged outside the air passage is discharged from the discharge port of the electrostatic atomizer, then rides on the wind from the air outlet of the air conditioner and enters the room. It is intended to be diffused.

本発明は、静電霧化によって得たミストは静電霧化装置の放出口から吐出された後、空調装置の吹き出し口からの風に乗って室内に拡散されるものであり、吹き出し口に至るまでの送風路内でミストを発生させたりミストを混合するものではないために、水の生成に関する問題やミストの消失といった問題を招くことがないものである。   In the present invention, the mist obtained by electrostatic atomization is discharged from the discharge port of the electrostatic atomizer and then diffused into the room by riding on the wind from the air outlet of the air conditioner. Since mist is not generated or mixed with the mist in the entire air passage, the problem of water generation and the problem of disappearance of mist are not caused.

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と、図２は車載用の空調装置２の一例を示しており、ブロア２０とフィルタ２２とエバポレータ２３とを備えて、吸い込み口２１から吸い込んだ車室内空気（並びに車室外空気）を調整した後、送風路２４を通じて複数の吹き出し口２５から車室内に吹き出すものとして形成されている。   Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. FIG. 2 shows an example of an in-vehicle air conditioner 2, which includes a blower 20, a filter 22, and an evaporator 23. After adjusting the sucked vehicle interior air (and vehicle exterior air), the air is blown out from the plurality of outlets 25 into the vehicle interior through the air passage 24.

静電霧化装置１は、上記複数の吹き出し口２５のうちの一つに隣接して配置されたもので、図１に示すように、放電電極１１と、この放電電極１１を囲む絶縁材からなる筒体の先端開口部に配設されて上記放電電極１１に対向する対向電極１２と、上記放電電極１１を冷却することで空気中の水分を放電電極上に結露させる冷却手段１３と、放電電極１１と対向電極１２との間に高電圧を印加する高圧電源部（図示せず）とからなるもので、ペルチェ素子で構成されている上記冷却手段１３は放熱用フィン１４を備えている。   The electrostatic atomizer 1 is disposed adjacent to one of the plurality of outlets 25. As shown in FIG. 1, the electrostatic atomizer 1 includes a discharge electrode 11 and an insulating material surrounding the discharge electrode 11. A counter electrode 12 which is disposed at the front end opening of the cylindrical body and which faces the discharge electrode 11, a cooling means 13 for condensing moisture in the air on the discharge electrode by cooling the discharge electrode 11, and a discharge The cooling means 13 is composed of a high voltage power supply unit (not shown) for applying a high voltage between the electrode 11 and the counter electrode 12.

この静電霧化装置１では、冷却手段１３で放電電極１１を冷却することで空気中の水分を結露させて放電電極１１上に結露水を生成し、この結露水を放電電極１１と対向電極１２との間の放電によって静電霧化させてナノメータサイズの帯電微粒子水（ミスト）Ｍを発生させるのであるが、このようにして発生させたミストＭは、放電電極１１を囲む筒体の先端開口部を放出口としてこの放出口から外部に吐出される。 In this electrostatic atomizer 1, the discharge electrode 11 is cooled by the cooling means 13 to condense moisture in the air to generate condensed water on the discharge electrode 11, and this condensed water is used as the discharge electrode 11 and the counter electrode. 12 is generated by electrostatic atomization by discharge between the discharge electrode 12 and the nanometer-sized charged fine particle water (mist) M. The mist M generated in this way is the tip of the cylinder surrounding the discharge electrode 11. The opening is used as a discharge port and discharged from the discharge port.

ここにおいて、上記静電霧化装置１はその放出口が空調装置２における吹き出し口２５とほぼ同面に位置するように配設されているとともに、放出口の延長線が空調装置２における吹き出し口２５から吐出される風の吐出方向と交叉するように設置されており、このために静電霧化装置１の放出口から吐出されたミストＭは、吹き出し口２５から吐出される風の流れに乗って車室内に拡散される。   Here, the electrostatic atomizer 1 is disposed so that the discharge port thereof is positioned substantially on the same plane as the blowout port 25 in the air conditioner 2, and the extended line of the discharge port is the blowout port in the air conditioner 2. For this reason, the mist M discharged from the discharge port of the electrostatic atomizer 1 is changed into the flow of the wind discharged from the blower port 25. Ride and diffuse into the passenger compartment.

また、静電霧化装置１は、空調装置２における吹き出し口２５に至る送風路２４外に設置されており、このために放電電極２上への結露水の生成や静電霧化に関して、送風路２４内の流れる調整された空気の影響を受けることがなく、ミストＭの発生を確実に行うことができる。   Moreover, the electrostatic atomizer 1 is installed outside the ventilation path 24 which leads to the blower outlet 25 in the air conditioner 2, and for this purpose, the generation of condensed water on the discharge electrode 2 and electrostatic atomization are performed. The mist M can be reliably generated without being affected by the regulated air flowing in the passage 24.

なお、図示例では複数存在している吹き出し口２５のうちの一つに隣接させて静電霧化装置１を設けたものを示したが、複数の吹き出し口２５に夫々隣接させて複数の静電霧化装置１を設けたものであってもよいのはもちろんである。   In the illustrated example, the electrostatic atomizer 1 is provided adjacent to one of the plurality of outlets 25. However, the static atomizer 1 is provided adjacent to the plurality of outlets 25. Of course, the one provided with the electroatomizer 1 may be used.
