Description

この発明は、空気清浄機又は脱臭機に関するものである。   The present invention relates to an air cleaner or a deodorizer.
従来の技術Conventional technology
喫煙所等のたばこの喫煙量が多い場所や臭気ガスが多く発生する場所では、煙や臭気が充満するので、その除去のために空気清浄機や脱臭機等が設置されている。しかし、脱臭に関しては、満足できる性能を発揮していない。また、衣類、カーペット、壁などに臭い物質が付着すると、空気清浄機等では除去することが難しく、喫煙所等から離れた後も衣類に臭いが付着し、不快である。   Smoke and odor are filled in places where there is a large amount of cigarette smoking, such as a smoking area, or where a lot of odor gas is generated. However, with respect to deodorization, satisfactory performance is not exhibited. Also, if odorous substances adhere to clothes, carpets, walls, etc., it is difficult to remove them with an air cleaner or the like, and odors adhere to clothes even after leaving a smoking area, which is uncomfortable.
従来は、衣類等に付着した臭いを除去するために、消臭剤を霧吹き等で衣類に吹き付け、臭いをマスキングしたり除去したりしている。しかし、霧吹きで液体を噴霧した場合、液体の粒径が大きく、吹きつけムラが多いために消臭剤が有効に使用されていないのが現状である。また、液体の粒径が大きいために、床や地面に落下するスピードが速くて浮遊している時間が短く、衣類等の裏側には付着しにくい。   Conventionally, in order to remove odors attached to clothes or the like, a deodorant is sprayed on the clothes with a spray or the like to mask or remove the odors. However, when the liquid is sprayed by spraying, the deodorant is not effectively used because the liquid has a large particle size and a large amount of spray unevenness. In addition, since the liquid has a large particle size, the speed of falling on the floor or the ground is high, and the floating time is short, and it is difficult to adhere to the back side of clothing or the like.
ところで、静電霧化の技術は、塗装や農薬散布など様々な分野に応用されている。静電霧化とは、液体に高電圧を印加し、電界中に液体をさらすと水が霧化するという現象である。このしくみは、液体表面の電界が大きくなると、表面に働く静電気力によって多数の微粒状液滴が発生する。液体が微粒子化すると、単位質量あたりの表面積が大きくなると同時に、液滴が同極に帯電しているので、斥力によって液体は広い範囲に散布される。   By the way, electrostatic atomization technology is applied to various fields such as painting and agricultural chemical application. Electrostatic atomization is a phenomenon in which water is atomized when a high voltage is applied to the liquid and the liquid is exposed to an electric field. In this mechanism, when the electric field on the liquid surface increases, a large number of fine droplets are generated by the electrostatic force acting on the surface. When the liquid is finely divided, the surface area per unit mass increases, and at the same time, the liquid droplets are charged to the same polarity, so that the liquid is dispersed over a wide range by repulsive force.
そこで、この発明は、このような静電霧化の技術に着目し、上述の問題点を解決できる空気清浄機又は脱臭機を提案したものである。   Therefore, the present invention proposes an air purifier or a deodorizer capable of solving the above-mentioned problems by paying attention to such an electrostatic atomization technique.
すなわち、この発明は、液体を静電霧化する際に液体にマイナスの電荷を帯電させて噴霧することによりマイナスイオン効果を生じるようにしたことを特徴とする。   That is, the present invention is characterized in that a negative ion effect is produced by charging a liquid with a negative charge and spraying the liquid when the liquid is electrostatically atomized.
静電気が帯電することによって、静電霧化した液体は、粒径が小さくなると同時に、静電気的に斥力が働くために広範囲にわたって噴霧することができる。また、噴霧された液体は、静電気を帯びているために衣類の裏側にも付着させることができる。   When the static electricity is charged, the electrostatic atomized liquid can be sprayed over a wide range since the particle size becomes small and the repulsive force works electrostatically. Further, since the sprayed liquid is charged with static electricity, it can be attached to the back side of the clothing.
現在の室内環境は、気密性が高いため、一定微粒子や有害ガスに汚染されると室内に滞留することになる。その対策として空気清浄機や脱臭機等を用いているが、汚染物質が常に排出されている状態では満足な効果が得られない。   Since the current indoor environment is highly airtight, it will stay in the room if it is contaminated with certain fine particles or harmful gases. As countermeasures, air purifiers, deodorizers, and the like are used, but satisfactory effects cannot be obtained when pollutants are constantly discharged.
そこで、請求項2に係る発明では、帯電させて噴霧された液体と同時に浮遊微粒子等を静電気にて吸着するための静電吸着部を備える。   In view of this, the invention according to claim 2 includes an electrostatic adsorption unit for adsorbing suspended fine particles and the like with static electricity simultaneously with the liquid sprayed by charging.
静電霧化によって帯電した液体は、浮遊微粒子や有害ガスに電荷を与えるので、電荷を与えられた有害物質等は、接地されている面に引き付けられるようになって空気中より除去できるようになる。   The liquid charged by electrostatic atomization gives electric charge to airborne particulates and harmful gases, so that the harmful substances that are charged can be attracted to the grounded surface and removed from the air. Become.
市販されているマイナスイオン発生器のほとんどは、空気にマイナスイオンの電荷を帯電させている。空気は、誘電率が低いため、効率良く帯電させることが難しく、マイナスイオンの持つ効果を充分に発揮させることができない。また、オゾン等の生成物を生じる。本発明では静電霧化される液体粒にマイナスの電荷を帯電させるものであって、噴霧された液体は、空気に比べ誘電率が高いために効率よく帯電させることができる。   Most negative ion generators on the market charge negative ions in the air. Since air has a low dielectric constant, it is difficult to charge it efficiently, and the effects of negative ions cannot be fully exhibited. In addition, products such as ozone are produced. In the present invention, the negatively charged liquid particles are charged in the electrostatic atomization, and since the sprayed liquid has a higher dielectric constant than air, it can be charged efficiently.
発明の実施の形態BEST MODE FOR CARRYING OUT THE INVENTION
次に、この発明の実施の形態を図面にしたがって説明する。   Next, embodiments of the present invention will be described with reference to the drawings.
図1は、この発明による消臭剤噴霧装置の概要構成を示し、液状の消臭剤(水滴5)を噴射するノズル1と、これにて噴射される消臭剤(水滴5)に静電気を帯電させて霧化するために高電圧の電界を形成する帯電部2と、その帯電部2を帯電させる高電圧電源6とからなる。この例の帯電部2は、ノズル1から噴射される水柱3を、帯電電極4にて誘電帯電法により静電霧化し、つまり高電圧の電界を通過させることにより粒径を小さくして、帯電した微粒子の水滴5として噴霧する。   FIG. 1 shows a schematic configuration of a deodorant spraying apparatus according to the present invention, in which static electricity is applied to a nozzle 1 for ejecting a liquid deodorant (water droplet 5) and the deodorant (water droplet 5) ejected thereby. The charging unit 2 forms a high-voltage electric field for charging and atomizing, and the high-voltage power source 6 charges the charging unit 2. In this example, the charging unit 2 electrostatically atomizes the water column 3 ejected from the nozzle 1 by the dielectric charging method at the charging electrode 4, that is, by passing a high voltage electric field to reduce the particle size, The water droplets 5 are sprayed as fine particles.
図2はその一例で、ノズル1の一部を円筒形の帯電電極4内に突入させ、高電圧電源6によりノズル1をプラス極、帯電電極4をマイナス極として高電圧を印加し、ノズル1から噴射される微粒子の水滴5をマイナスに帯電させて静電霧化する。このようにマイナスに帯電させた場合には、マイナスイオン効果も発揮できる。   FIG. 2 shows an example of this. A part of the nozzle 1 is inserted into the cylindrical charging electrode 4, and a high voltage is applied by the high voltage power source 6 using the nozzle 1 as a positive electrode and the charging electrode 4 as a negative electrode. The water droplets 5 of the fine particles ejected from the nozzle are negatively charged and electrostatically atomized. When charged negatively in this way, the negative ion effect can also be exhibited.
水滴5に、ビタミンC等の酸化防止剤や殺菌剤を混合し、これらを同時に静電霧化して噴霧することにより、酸化防止剤にて空気中に滞留している活性酸素を除去したり、殺菌剤にて殺菌することができる。   By mixing antioxidants such as vitamin C and bactericides with water droplets 5 and simultaneously spraying them by electrostatic atomization, active oxygen staying in the air can be removed with antioxidants, It can be sterilized with a disinfectant.
高電圧電源6として交流高電圧電源を用いれば、プラス・マイナスの両極性の電荷を微粒子の水滴5に帯電させて、これにて除電することができる。帯電電極4による帯電部4の先に、接地された静電吸着部(図示せず)を設置すれば、水滴5と同時に空気中の浮遊微粒子等を静電気にて吸着回収することができる。   If an AC high-voltage power supply is used as the high-voltage power supply 6, the positive and negative polar charges can be charged to the water droplets 5 of the fine particles, and the charge can be eliminated. If a grounded electrostatic adsorption unit (not shown) is installed at the tip of the charging unit 4 by the charging electrode 4, floating particles in the air can be adsorbed and collected simultaneously with water droplets 5.
図3に示すように、ノズル1自体に高電圧を直接印加すれば、ノズル1自体を帯電部として、水滴5をノズル1にて噴霧と同時に直接帯電させることができる。図2の構造および図3の構造のいずれも、空気清浄機に内蔵して使用することができる。   As shown in FIG. 3, when a high voltage is directly applied to the nozzle 1 itself, the water droplet 5 can be directly charged at the same time as spraying by the nozzle 1 using the nozzle 1 itself as a charging unit. Either the structure of FIG. 2 or the structure of FIG. 3 can be used by being incorporated in an air purifier.
請求項1の発明によれば、液体を静電霧化して広範囲に噴霧でき、また効率良く噴霧することによって液体の使用量を節約することができる。また、液体をマイナスの電荷を帯びるように静電霧化するので、マイナスイオン効果も同時に期待できる。   According to the first aspect of the present invention, the liquid can be sprayed in a wide range by electrostatic atomization, and the amount of liquid used can be saved by spraying efficiently. In addition, since the liquid is electrostatically atomized so as to have a negative charge, a negative ion effect can be expected at the same time.
請求項2の発明によれば、静電霧化した液体は電荷を持っていて空気中に浮遊しているダストや有害ガスに電荷を与え、電荷を与えられたダストや有害ガスを静電吸着部にて空気中から吸着除去することができる。   According to the second aspect of the present invention, the electrostatic atomized liquid has an electric charge, gives electric charge to dust and harmful gas floating in the air, and electrostatically adsorbs the charged dust and harmful gas. It can be adsorbed and removed from the air at the part.
