Description

本発明は、静電霧化装置に関するものである。   The present invention relates to an electrostatic atomizer.

脱臭を行うことができる空気清浄機能を有するものとして、特許文献1に示された静電霧化装置がある。これは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、ここで得られたミストは脱臭や防黴性を有することが知られている。このナノメータサイズの帯電微粒子水を発生させる静電霧化装置を空気調和機に組み込んだものが特許文献2に示されている。これは、空気調和機から吹き出す風とともに上記帯電微粒子水を室内に供給するものであり、カーテンや壁などに付着した臭気成分を取り除くことができる上に空気調和機の送風経路内に発生した黴による臭気も取り除くことができる。   There exists an electrostatic atomizer shown by patent document 1 as what has an air purifying function which can perform a deodorizing. This generates nanometer-sized charged fine particle water (mist), and the mist obtained here is known to have deodorization and antifungal properties. Patent Document 2 discloses that an electrostatic atomizer that generates nanometer-sized charged fine particle water is incorporated in an air conditioner. This is to supply the charged fine particle water together with the wind blown out from the air conditioner to remove odorous components adhering to the curtains and walls, etc. Odor can be removed.

しかし、上記静電霧化装置は送風経路中に配置されていることから、ナノメータサイズの帯電微粒子水を送風に乗せて室内に送り出すことができるようにした場合、静電霧化装置が送風経路内において送風抵抗となって空気調和機本来の性能の妨げになってしまう。   However, since the electrostatic atomizer is disposed in the air passage, when the nanometer-sized charged fine particle water can be put into the air and sent out indoors, the electrostatic atomizer is in the air passage. It becomes a ventilation resistance in the inside and hinders the original performance of the air conditioner.

そこで、本願発明者は管を介して帯電微粒子を放出させることで、静電霧化装置を送風経路外に配設することを考えたが、帯電微粒子水の管内壁への付着等によって放出される帯電微粒子水の量が少なくなる恐れがある。   Therefore, the present inventor considered that the electrostatic atomizer is disposed outside the ventilation path by discharging charged fine particles through the tube, but the charged fine particles are released due to adhesion of the water to the inner wall of the tube. The amount of charged fine particle water may decrease.

本発明は上記問題点に鑑みて発明したものであって、管を介して帯電微粒子水(ミスト)を放出するにあたって、当該放出を効率良く行うことができ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 problems, and provides an electrostatic atomizer that can efficiently perform discharge of charged fine particle water (mist) through a tube. It is to be an issue.

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、放電電極上に供給された水を放電によって帯電微粒子水とする静電霧化装置であって、前記帯電微粒子水を外部に放出するための放出口と、該放出口に一端が接続され他端が開口する管とを備え、該管は、緩やかな曲率又は小さな曲率の屈曲部を有するとともに、導電性の少なく且つ帯電しにくい材質で形成されていることに特徴を有している。   In order to solve the above problems, an electrostatic atomizer according to the present invention is an electrostatic atomizer that uses charged water as a charged fine particle water by discharging water supplied onto a discharge electrode. A discharge opening for discharging, and a tube having one end connected to the discharge port and an opening at the other end. The tube has a bent portion having a gentle curvature or a small curvature, and has a low conductivity and is charged. It is characterized by being made of a difficult material.

前記管は前記屈曲部の曲率を規定することができる剛性を有する材質で形成されていることが好ましい。   The tube is preferably formed of a material having rigidity capable of defining the curvature of the bent portion.

空気吸い込み口から吸い込んだ空気をハウジング内の送風経路を経て空気吹き出し口から吐出する空気調和機に配設され、前記管の前記他端が前記送風経路内部に開口していることが好ましい。   It is preferable that the air sucked from the air suction port is disposed in an air conditioner that discharges air from the air blowout port through a blower path in the housing, and the other end of the pipe is opened inside the blower path.

本発明は、帯電微粒子水(ミスト)の管を介した放出を効率良く行いやすくすることができる。   The present invention makes it easy to efficiently discharge charged fine particle water (mist) through a tube.

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1において、外殻を構成するハウジング2の前面上部に空気吸い込み口6が設けられるとともに前面下部にルーバ8を備えた空気吹き出し口7が設けられている空気調和機(の室内機)0は、その内部に熱交換器1と横流ファンで形成されたファン3とが配設されている。また上記ハウジング2内には、空気吸い込み口6からファン3を経て空気吹き出し口7に至る送風経路5を形成するための隔壁4が配設されている。   Hereinafter, the present invention will be described with reference to the embodiment shown in the accompanying drawings. In FIG. The air conditioner (indoor unit) 0 provided with the port 7 is provided with a heat exchanger 1 and a fan 3 formed of a cross-flow fan. In the housing 2, a partition wall 4 is provided for forming a blowing path 5 from the air suction port 6 through the fan 3 to the air blowing port 7.

そして上記ハウジング2内の下部後方部分は、上記隔壁4によって送風経路5から区画されている部分であるとともに、排水用のドレインパイプがハウジング2の右端乃至左端から外部に引き出される際に使用されるだけでのデッドスペースであり、ドレインパイプを通す場合においてもその全域が使用されるわけではない部分であるが、ナノメータサイズの帯電微粒子水を発生させる静電霧化装置11は、上記デッドスペースに設置してある。   The lower rear portion in the housing 2 is a portion partitioned from the air blowing path 5 by the partition wall 4 and is used when a drain pipe for drainage is pulled out from the right end to the left end of the housing 2. The electrostatic atomizer 11 that generates nanometer-sized charged fine particle water is used as the dead space in the dead space. It is installed.

図2及び図3にここで用いている静電霧化装置11を示す。曲線を描いている上記隔壁4に合わせて一面が傾斜曲面となっている静電霧化装置11は、その下端部に静電霧化ユニットを、上部に高圧トランスや制御回路といった回路ブロック18を、中段に冷却用のファン17を納めたもので、静電霧化ユニットは放電電極12、放電電極12に対向する対向電極13、上記放電電極12を冷却して空気中の水分を放電電極12上に結露させる熱電素子(ペルチェ素子)14、そして熱電素子14の放熱側に連結された放熱フィン15とからなるもので、放電電極12上に結露で生じた水を放電電極12と対向電極13との間の放電によってナノメータサイズの帯電微粒子水(ミスト)とする。上記ファン17は放熱フィン14に風を当てて冷却するためのものである。   2 and 3 show the electrostatic atomizer 11 used here. The electrostatic atomizer 11 whose one surface is an inclined curved surface in accordance with the curved partition wall 4 has an electrostatic atomizer unit at the lower end and a circuit block 18 such as a high-voltage transformer and a control circuit at the upper portion. The cooling fan 17 is housed in the middle stage, and the electrostatic atomization unit cools the discharge electrode 12, the counter electrode 13 facing the discharge electrode 12, and the discharge electrode 12, and removes moisture in the air to the discharge electrode 12. It consists of a thermoelectric element (Peltier element) 14 that condenses on top and a radiation fin 15 connected to the heat radiation side of the thermoelectric element 14. Water generated by condensation on the discharge electrode 12 is discharged to the discharge electrode 12 and the counter electrode 13. It becomes nanometer-sized charged fine particle water (mist) by the discharge between. The fan 17 is used to cool the radiating fin 14 by blowing air.

そして上記静電霧化装置11で発生させたミストは、その側面に位置する放出口16から外部に放出するのであるが、ここでは放出口16に一端を接続した管21を設けるとともに、この管21の他端を隔壁4に位置させて上記送風経路5内において開口させているとともに、この位置における送風方向と上記開口方向とをほぼ一致させている。   The mist generated by the electrostatic atomizer 11 is discharged to the outside from the discharge port 16 located on the side surface. Here, a tube 21 having one end connected to the discharge port 16 is provided. The other end of 21 is positioned in the partition wall 4 to be opened in the air blowing path 5, and the air blowing direction at this position is substantially coincident with the opening direction.

このために静電霧化装置11からのミストは送風経路5内を流れる風に乗って空気吹き出し口7から外部に放出されるものである。また、静電霧化装置11そのものは送風経路5中になく、ハウジング2内のデッドスペースに配置されているために、送風抵抗となることがないのはもちろん、その設置のためのスペースをハウジング2内に新たに確保する必要もない。   For this reason, the mist from the electrostatic atomizer 11 is discharged to the outside from the air outlet 7 along with the wind flowing in the air blowing path 5. Moreover, since the electrostatic atomizer 11 itself is not in the ventilation path 5 and is disposed in the dead space in the housing 2, it does not become a blowing resistance. There is no need to newly secure within 2.

ここで、上記放出口16は側方に開口し、管21の他端は前方に向けて開口することから、管21として屈曲部分を備えたものを用いなくてはならないが、この屈曲部分の曲率半径がきわめて小さいと、ミストが管21の内壁に付着して外部へと流れ出るミストの量が少なくなる。また、柔らかい材質のもので管21を形成して屈曲部を設けた場合、時として屈曲部において管21が扁平な状態になって管路が急激に狭くなり、流路抵抗を著しく増加させてミストの吐出の妨げとなってしまうことがある。   Here, since the discharge port 16 opens to the side and the other end of the tube 21 opens to the front, a tube 21 having a bent portion must be used. When the curvature radius is extremely small, the amount of mist that adheres to the inner wall of the tube 21 and flows to the outside decreases. Further, when the bent portion is provided by forming the tube 21 with a soft material, sometimes the tube 21 becomes flat in the bent portion, the pipe line becomes abruptly narrowed, and the flow resistance is significantly increased. It may interfere with the discharge of mist.

このために、緩やかな曲率の屈曲部しか必要でない場合はともかく、屈曲部の曲率が小さくなる場合においては、管21としては曲率を規定することができる剛性を有する材質、更に好ましくは導電性の少なく且つ帯電しにくい材質、たとえばABS,PS、PP、PAなどのプラスチック材料で形成しておくことが、ミストの管を介した放出を効率良く行うことができ好ましい。   For this reason, if only a bent portion having a gentle curvature is required, the tube 21 is made of a material having rigidity capable of defining the curvature, more preferably a conductive material when the curvature of the bent portion is small. It is preferable to use a material that is small and difficult to be charged, for example, a plastic material such as ABS, PS, PP, PA, etc., because it allows efficient discharge through the mist tube.

上記管21の他端はルーバ8に添わせて、ルーバ8近傍で開口させてもよい。風を送ろうとしている方向にミストも放出することから、ミストを室内に容易に行き渡らせることができる。   The other end of the tube 21 may follow the louver 8 and be opened near the louver 8. Since the mist is also released in the direction in which the wind is going to be sent, the mist can be easily distributed in the room.

上記ルーバ8部分で管21の他端を開口させるにあたっては、図4に示すように、一端がルーバ8の先端縁で開口するとともに他端がルーバ8の回動用の軸80と同軸で形成されたコネクタ82となっている管路をルーバ8に一体に形成し、管21の他端を上記コネクタ82に軸80の軸回りに回動自在に連結してもよい。この場合、ルーバを回動させることが管に影響を与えることがなく、ルーバ8の角度を変更しても、管21における屈曲部の曲率が変化することがないために、ルーバ8の角度に拘わらず、安定したミスト放出を行うことができる。   When the other end of the tube 21 is opened at the louver 8 portion, as shown in FIG. 4, one end is opened at the leading edge of the louver 8 and the other end is formed coaxially with the pivot shaft 80 of the louver 8. A pipe line serving as the connector 82 may be formed integrally with the louver 8, and the other end of the pipe 21 may be connected to the connector 82 so as to be rotatable around the axis 80. In this case, rotating the louver does not affect the tube, and even if the angle of the louver 8 is changed, the curvature of the bent portion in the tube 21 does not change. Regardless, stable mist release can be performed.

上記実施例では、静電霧化装置11を隔壁4の後方とハウジング2内面との間のデッドスペースに配置したが、空気調和機0内の側端部等にも送風経路5外となるとともにデッドスペースとなっている部分が少なからず存在することから、このようなデッドスペースを利用して静電霧化装置11を配置してもよいのはもちろんである。   In the said Example, although the electrostatic atomizer 11 was arrange | positioned in the dead space between the back of the partition 4 and the housing 2 inner surface, while being outside the ventilation path 5 also in the side edge part in the air conditioner 0, etc. Since there are not a few portions that are dead spaces, it is a matter of course that the electrostatic atomizer 11 may be arranged using such dead spaces.
