Description

【０００１】
【発明の属する技術分野】
本発明は、イオン発生装置及びそれを備えた空気清浄機並びに空気調和機に関するものである。
【０００２】
【従来の技術】
近年、住環境の高気密化に伴い、室内等の居住空間に浮遊する人体に有害な成分を取り除き、健康で快適な生活を送りたいという要望が強くなっている。この要望に応えるため、各種のフィルタを備えた空気清浄機が開発されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、このような空気清浄機では、空間にある空気を吸引してフィルタにより汚染物質を吸着又は分解する方式であるため、長期にわたる使用によりフィルタの交換等のメンテナンスが不可欠であり、しかも、フィルタの特性が充分でないため、満足のいく性能が得られていない。
【０００４】
それに対し、イオン発生装置を用いて、空気中のイオン濃度を増加させる空気清浄機や空気調和機も開発されているが、現在、市販されているものは、負イオンのみを発生させるものであったため、負イオンによる人間をリラックスさせる効果はある程度期待できるものの、空気中の浮遊細菌の積極的な除去についてはほとんど効果が認められていない。
【０００５】
また、このような従来のイオン発生装置は、直流高電圧方式やパルス高電圧方式を用いて負イオンを放電針から発生させるものであったため、電圧として５ｋＶ以上の高電圧を必要とし、このため、製品や周辺の機器等に塵や埃が多く付着する問題が生じている。更に、高電圧を使用するために機器の安全性の確保に課題があり、安全回路を設置する等の対策が必要であった。
【０００６】
そこで、このような問題に鑑みて鋭意研究を重ねた結果、本発明者らは比較的小さな交流電圧の印加により滅菌効果に優れた活性種を発生するイオン発生装置の開発に成功した。そして、このイオン発生装置を空気清浄機や空気調和機に搭載することで、上記活性種を室内等の居住空間に送出して浮遊細菌を効率よく除去できることを実験により確認した。
【０００７】
このイオン発生装置は、筒状又は板状のガラス等の絶縁体を挟んで対向するメッシュ状の電極間に交流電圧を印加することにより正イオンと負イオンを同時に発生させるように構成されたものである。
【０００８】
このイオン発生装置の動作原理について説明する。イオン発生装置の電極間に交流高電圧を印加すると、大気中で放電等の電離現象が起こり、正イオン及び負イオンが同時に発生する。このとき、正イオンとしてはＨ+（Ｈ2Ｏ）n、負イオンとしてはＯ2 -（Ｈ2Ｏ）nが最も安定に生成する。
【０００９】
これらのイオンは、正イオン又は負イオン単独では空気中の浮遊細菌に対し、格別な効果はない。しかし、これらのイオンが同時に生成すると、化学反応によって活性種である過酸化水素Ｈ2Ｏ2又は水酸化ラジカル・ＯＨが生成する。このＨ2Ｏ2又は・ＯＨは、極めて強力な活性を示すため、これにより空気中の浮遊細菌を除去することができる。
【００１０】
しかしながら、このようなイオン発生装置は、筒状又は板状の絶縁体を挟んでメッシュ状の電極を対向させて設けた構成であるため、電極を固定する際の絶縁体との密着の再現性に課題があった。また、電極に空気中の塵や埃が付着した場合、清掃等のメンテナンスが困難であるという課題があった。
【００１１】
本発明は、上記の課題に鑑みてなされたものであり、メンテナンスが容易で安定した性能が再現性よく得られるイオン発生装置を提供することを目的とする。また、本発明は、そのようなイオン発生装置を備えた空気清浄機及び空気調和機を提供することを目的とする。
【００１２】
【課題を解決するための手段】
上記目的を達成するため本発明によるイオン発生装置は、絶縁体に埋設された第１電極と、前記絶縁体の表面に設けた第２電極とを対向させ、メッシュ状の電界集中が起こりやすい形状からなる前記第１及び第２電極間に交流電圧を印加することにより正イオンとしてＨ+（Ｈ2Ｏ）nと、負イオンとしてＯ2―（Ｈ2Ｏ）nとを発生させて、空気中に浮遊する浮遊細菌を除去すことを特徴とする。
【００１３】
これによると、絶縁体への電極の固定が容易となるとともに、絶縁体に埋め込まれた第１電極に塵や埃が付着することがない。
【００１５】
また、前記イオン発生装置を空気清浄機又は空気調和機に搭載したことにより、上記活性種を空間の隅々まで行き届かせて適度な除菌効果を得ることができる。
【００１６】
その場合、前記イオン発生装置を空気清浄機又は空気調和機の送風回路の空気吹出口の内部近傍に設けると、上記活性種を効率よく空間の隅々まで行き届かせて速やかに適度な除菌効果を得ることができる。
【００１７】
【発明の実施の形態】
＜第１の実施形態＞
本発明の第１の実施形態について図面を参照して説明する。図１は本実施形態に係る空気清浄機の概略的な側面断面図である。図１において、１１は後述するするイオン発生装置、１２は空気吸込口、１３は空気吸込口１２の下流側に配設された除塵フィルタ、１４は送風ファン、１５は空気吹出口である。
【００１８】
次に、イオン発生装置１１の構成を説明する。図２はイオン発生装置の概略的な側面断面図であり、図３はそのイオン発生部を図２のＦの方向から見た平面図である。尚、図２はあくまで模式的に示した図であり、図３のガラス板２１を縦に切って断面で見ると、電極２２，２３はおびただしい数のメッシュとして存在するはずであるが、その一つ一つを図示するのは困難なので省略して示している。また、電極２２，２３の断面の厚みも、図２では分かりやすくするため誇張して示している。
【００１９】
図２及び図３に示すように、絶縁体であるガラス板２１（３５ｍｍ×３５ｍｍ、厚み３ｍｍ）には金属のメッシュからなる第１電極２２（３３ｍｍ×３３ｍｍ）が埋設されている。このような埋設は、所定のサイズの鋳型内において板状に溶融したガラス中に金属のメッシュを挿入して位置決めした後、ガラスを冷却して凝固させることで容易に行える。
【００２０】
このようにして第１電極２２を埋設したガラス板２１の表面に、同じく金属のメッシュからなる第２電極２３（３３ｍｍ×３３ｍｍ）を第１電極２２と対向するように接着により施した。このとき、第１電極２２と第２電極２３との間隔（図２中のｄ）が１ｍｍとなるように、金属メッシュのガラス中への上記位置決めがなされているものとする。また、１インチあたりのメッシュの目の粗さ（金属線の数）は、第１，第２電極２２，２３ともに４８ｍｅｓｈとした。尚、第１，第２電極２２，２３の材料としては、ステンレス（ＳＵＳ３０４）を用いた。
【００２１】
以上のように構成されるイオン発生装置１１の第２電極２３を接地電位として、第１，第２電極２２，２３間に高周波回路を用いて周波数２０ｋＨｚ、電圧３ｋＶ（実効値）の交流高電圧を印加した。
【００２２】
そして、このような条件において、イオン発生装置１１から発生するイオンを空気イオンカウンタによって測定した。移動度１ｃｍ2／Ｖｓｅｃ以上の小イオンを検出した結果、第２電極２３から距離が１０ｃｍの位置で、５万個／ｃｃ程度の正イオンと負イオンが同時に観測された。
【００２３】
このような特性を持つイオン発生装置１１を、図１に示すように、空気清浄機の送風回路の空気吹出口１５の内部近傍に設け、この空気清浄機による空気中の浮遊細菌に対する除去性能を評価した。容積１ｍ3の容器の中にこの空気清浄機を設置し、予め培地上で培養した一般生菌と真菌を容器内に散布した。
【００２４】
そして、イオン発生装置１１を動作させるとともに、空気清浄機の運転を開始し、所定の時間ごとに、細菌の濃度を測定した。測定は、エアーサンプラーを用いて、４０Ｌ／分の割合で容器内の空気を吸引し、４分間のサンプリングを行う方法を採用した。その結果を表１に示す。
【００２５】
【表１】

【００２６】
表１から明らかなように、空気清浄機の運転を開始してから３時間後、一般生菌は７１％、真菌は７６％を除去できた。従って、本実施形態に係るイオン発生装置を備えた空気清浄機によると、極めて良好に空気中の浮遊細菌の大部分を除去できることが確認できた。
【００２７】
＜第２の実施形態＞
本発明の第２の実施形態について図面を参照して説明する。図４は、本実施形態に係るイオン発生装置を備えた空気調和機の概略的な側面断面図である。図３において、１１は前述した本発明に係るイオン発生装置（図２、図３参照）、４２は空気吸込口、４３は空気吸込口４２の下流側に配設されたフィルタ、４４は送風ファン、４５は熱交換器、４６は空気吹出口である。
【００２８】
上記第１の実施形態の同様に、イオン発生装置１１を、図４に示すように、空気調和機の送風回路の空気吹出口４６の内部近傍に設け、この空気調和機による空気中の浮遊細菌に対する除去性能を評価した。容積１ｍ3の容器の中にこの空気調和機を設置し、予め培地上で培養した一般生菌と真菌を容器内に散布した。
【００２９】
そして、イオン発生装置１１を動作させるとともに、空気調和機の運転を開始し、所定の時間ごとに、細菌の濃度を測定した。測定は、エアーサンプラーを用いて、４０Ｌ／分の割合で容器内の空気を吸引し、４分間のサンプリングを行う方法を採用した。その結果を表２に示す。
【００３０】
【表２】

表２から明らかなように、空気調和機の運転を開始してから３時間後、一般生菌は７４％、真菌は７８％を除去できた。従って、本実施形態に係るイオン発生装置を備えた空気調和機によると、極めて良好に空気中の浮遊細菌の大部分を除去できることが確認できた。
【００３２】
尚、本発明は上記の実施形態に限定されず、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。例えば、電極の形状をメッシュ状としたが、その他、格子状、平行線状、パンチングメタルのように電界の集中が起こりやすい形状であればよい。また、絶縁体として、平板状のガラス板を使用する場合について説明したが、円筒状の絶縁体であっても同様の効果が得られることは言うまでもない。更に、絶縁体の材料としては、ガラス以外にも樹脂等が使用可能であるが、表面の耐酸化性の問題からガラスが望ましい。
【００３３】
【発明の効果】
以上説明したように本発明によると、絶縁体に埋設された第１電極と、前記絶縁体の表面に設けた第２電極とを対向させ、前記第１及び第２電極間に交流電圧を印加することにより正イオンと負イオンを発生させるようなイオン発生装置の構成としたことにより、前記絶縁体への電極の固定が容易となりるとともに、イオン発生装置から再現性よく安定して充分な正イオンと負イオンを発生させることができる。
【００３４】
また、絶縁体に埋設された第１電極は空気中に露出していないので、これに塵や埃が付着して汚染されることがなく、清掃等のメンテナンスの手間が大幅に省ける。
【００３５】
そして、このようなイオン発生装置を空気清浄機又は空気調和機の送風回路の吹出口近傍に配設することで、正負のイオン同士の化学反応によって生ずる活性種を空間に送出して空間中の浮遊細菌を効率よく除去できる。

BACKGROUND OF THE INVENTION
The present invention relates to an ion generator, an air purifier equipped with the ion generator, and an air conditioner.
[0002]
[Prior art]
In recent years, with the increase in airtightness in the living environment, there is an increasing demand for a healthy and comfortable life by removing components harmful to the human body floating in a living space such as a room. In order to meet this demand, air purifiers equipped with various filters have been developed.
[0003]
[Problems to be solved by the invention]
However, in such an air purifier, since the air in the space is sucked and the pollutant is adsorbed or decomposed by the filter, maintenance such as replacement of the filter is indispensable for long-term use. However, satisfactory performance has not been obtained due to insufficient characteristics.
[0004]
On the other hand, air purifiers and air conditioners that use ion generators to increase the ion concentration in the air have been developed, but what are currently on the market are those that generate only negative ions. Therefore, although the effect of relaxing humans by negative ions can be expected to some extent, little effect has been observed for the active removal of airborne bacteria in the air.
[0005]
In addition, since such a conventional ion generator generates negative ions from a discharge needle using a DC high voltage method or a pulse high voltage method, a high voltage of 5 kV or more is required as a voltage. There is a problem that a lot of dust or dust adheres to products and peripheral devices. Furthermore, since a high voltage is used, there is a problem in ensuring the safety of the equipment, and measures such as installing a safety circuit are necessary.
[0006]
Thus, as a result of intensive studies in view of such problems, the present inventors have succeeded in developing an ion generator that generates active species having an excellent sterilization effect by applying a relatively small alternating voltage. Then, it was confirmed by experiments that the active species can be sent to a living space such as a room and the floating bacteria can be efficiently removed by mounting the ion generator in an air purifier or an air conditioner.
[0007]
This ion generator is configured to generate positive ions and negative ions simultaneously by applying an alternating voltage between mesh electrodes facing each other across an insulator such as a cylindrical or plate-like glass. It is.
[0008]
The operating principle of this ion generator will be described. When an alternating high voltage is applied between the electrodes of the ion generator, an ionization phenomenon such as discharge occurs in the atmosphere, and positive ions and negative ions are generated simultaneously. At this time, H + (H 2 O) n as positive ions and O 2 − (H 2 O) n as negative ions are most stably generated.
[0009]
These ions have no particular effect on airborne bacteria by positive ions or negative ions alone. However, when these ions are generated at the same time, hydrogen peroxide H 2 O 2 or hydroxyl radical.OH, which is an active species, is generated by a chemical reaction. Since this H 2 O 2 or .OH exhibits a very strong activity, it is possible to remove airborne bacteria in the air.
[0010]
However, since such an ion generator has a configuration in which a mesh-like electrode is provided facing a cylindrical or plate-like insulator, the reproducibility of adhesion with the insulator when fixing the electrode There was a problem. In addition, when dust or dirt in the air adheres to the electrode, there is a problem that maintenance such as cleaning is difficult.
[0011]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an ion generator that can be easily maintained and has stable performance with good reproducibility. Moreover, an object of this invention is to provide the air cleaner and air conditioner provided with such an ion generator.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, an ion generator according to the present invention has a shape in which a first electrode embedded in an insulator and a second electrode provided on the surface of the insulator face each other, and a mesh-like electric field concentration is likely to occur. and H + (H 2 O) n as positive ions by applying an alternating voltage between the first and second electrodes made of, O 2 as a negative ion - in (H 2 O) to generate and n, air It is characterized by removing floating bacteria floating in it.
[0013]
According to this, it becomes easy to fix the electrode to the insulator, and dust or dust does not adhere to the first electrode embedded in the insulator.
[0015]
Moreover, by mounting the ion generator in an air purifier or an air conditioner, the active species can reach all corners of the space, and an appropriate sterilizing effect can be obtained.
[0016]
In that case, if the ion generator is provided in the vicinity of the air outlet of the air circuit of the air cleaner or air conditioner, the active species can be efficiently distributed to every corner of the space to quickly and appropriately disinfect. An effect can be obtained.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
<First Embodiment>
A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side sectional view of an air cleaner according to the present embodiment. In FIG. 1, 11 is an ion generator to be described later, 12 is an air suction port, 13 is a dust filter disposed on the downstream side of the air suction port 12, 14 is a blower fan, and 15 is an air outlet.
[0018]
Next, the configuration of the ion generator 11 will be described. FIG. 2 is a schematic side cross-sectional view of the ion generator, and FIG. 3 is a plan view of the ion generator viewed from the direction F in FIG. Note that FIG. 2 is a schematic diagram only, and when the glass plate 21 of FIG. 3 is cut vertically and viewed in cross section, the electrodes 22 and 23 should exist as numerous meshes. Since it is difficult to illustrate one by one, it is omitted. Also, the thickness of the cross section of the electrodes 22 and 23 is exaggerated in FIG. 2 for easy understanding.
[0019]
As shown in FIGS. 2 and 3, a first electrode 22 (33 mm × 33 mm) made of a metal mesh is embedded in a glass plate 21 (35 mm × 35 mm, thickness 3 mm) which is an insulator. Such embedding can be easily performed by inserting and positioning a metal mesh in a glass melted in a plate shape in a mold of a predetermined size, and then cooling and solidifying the glass.
[0020]
Thus, the 2nd electrode 23 (33 mm x 33 mm) which consists of a metal mesh similarly was adhere | attached on the surface of the glass plate 21 which embedded the 1st electrode 22 so that the 1st electrode 22 might be opposed. At this time, it is assumed that the positioning of the metal mesh in the glass is performed so that the distance between the first electrode 22 and the second electrode 23 (d in FIG. 2) is 1 mm. The mesh per inch (number of metal wires) was 48 mesh for both the first and second electrodes 22 and 23. Stainless steel (SUS304) was used as the material for the first and second electrodes 22 and 23.
[0021]
An AC high voltage having a frequency of 20 kHz and a voltage of 3 kV (effective value) using a high-frequency circuit between the first and second electrodes 22 and 23 with the second electrode 23 of the ion generator 11 configured as described above as a ground potential. Was applied.
[0022]
Under such conditions, ions generated from the ion generator 11 were measured with an air ion counter. As a result of detecting small ions having a mobility of 1 cm 2 / Vsec or more, about 50,000 positive ions and negative ions were simultaneously observed at a distance of 10 cm from the second electrode 23.
[0023]
As shown in FIG. 1, the ion generator 11 having such characteristics is provided in the vicinity of the inside of the air outlet 15 of the blower circuit of the air purifier, and the air purifier removes airborne bacteria in the air. evaluated. This air cleaner was installed in a container having a volume of 1 m 3 , and general viable bacteria and fungi previously cultured on a medium were sprayed into the container.
[0024]
And while operating the ion generator 11, the operation | movement of the air cleaner was started and the density | concentration of bacteria was measured for every predetermined time. For the measurement, an air sampler was used to suck the air in the container at a rate of 40 L / min and perform sampling for 4 minutes. The results are shown in Table 1.
[0025]
[Table 1]
Figure 0003770783
[0026]
As is clear from Table 1, 3 hours after starting the operation of the air purifier, 71% of general viable bacteria and 76% of fungi could be removed. Therefore, according to the air cleaner provided with the ion generator which concerns on this embodiment, it has confirmed that most airborne bacteria in the air could be removed very favorably.
[0027]
<Second Embodiment>
A second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a schematic side cross-sectional view of an air conditioner including the ion generator according to the present embodiment. 3, 11 is the ion generator according to the present invention described above (see FIGS. 2 and 3), 42 is an air inlet, 43 is a filter disposed downstream of the air inlet 42, and 44 is a blower fan. , 45 is a heat exchanger, and 46 is an air outlet.
[0028]
As in the first embodiment, as shown in FIG. 4, the ion generator 11 is provided in the vicinity of the air outlet 46 of the blower circuit of the air conditioner, and airborne bacteria in the air by the air conditioner The removal performance against was evaluated. This air conditioner was installed in a container having a volume of 1 m 3 , and general viable bacteria and fungi previously cultured on a medium were sprayed into the container.
[0029]
And while operating the ion generator 11, the operation | movement of the air conditioner was started and the density | concentration of bacteria was measured for every predetermined time. For the measurement, an air sampler was used to suck the air in the container at a rate of 40 L / min and perform sampling for 4 minutes. The results are shown in Table 2.
[0030]
[Table 2]
Figure 0003770783
[0031]
As is apparent from Table 2, 3 hours after the start of the operation of the air conditioner, 74% of general viable bacteria and 78% of fungi could be removed. Therefore, according to the air conditioner provided with the ion generator which concerns on this embodiment, it has confirmed that most airborne bacteria in the air could be removed very favorably.
[0032]
In addition, this invention is not limited to said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, although the shape of the electrode is a mesh shape, other shapes may be used as long as the electric field concentration is likely to occur, such as a lattice shape, a parallel line shape, or a punching metal. Moreover, although the case where a flat glass plate was used as the insulator has been described, it goes without saying that the same effect can be obtained even with a cylindrical insulator. Further, as the material for the insulator, resin or the like can be used in addition to glass, but glass is desirable because of the problem of surface oxidation resistance.
[0033]
【The invention's effect】
As described above, according to the present invention, the first electrode embedded in the insulator is opposed to the second electrode provided on the surface of the insulator, and an AC voltage is applied between the first and second electrodes. By configuring the ion generator to generate positive ions and negative ions, it becomes easy to fix the electrode to the insulator, and from the ion generator, it is possible to achieve sufficient positive and stable reproducibility. Ions and negative ions can be generated.
[0034]
Further, since the first electrode embedded in the insulator is not exposed to the air, it is not contaminated by dust or dirt attached thereto, and maintenance work such as cleaning can be saved greatly.
[0035]
And by arranging such an ion generator near the blower outlet of the air circuit of the air cleaner or air conditioner, the active species generated by the chemical reaction between the positive and negative ions are sent to the space, Airborne bacteria can be removed efficiently.
