従来より、いわゆる空気清浄機（エアクリーナ）として、ペーパーフィルタなどの乾式フィルタを利用した空気清浄機が一般的に使用されている。このような乾式フィルタによる空気清浄機は、塵、埃、花粉などの粒子状の物質に対してはある程度の効果を発揮するものの、通常、ホルムアルデヒド、アセトアルデヒド、アンモニア、ダイオキシンといったガス状の有害物質を有効に取り除くことはできない。   Conventionally, as a so-called air cleaner (air cleaner), an air cleaner using a dry filter such as a paper filter is generally used. Although such air cleaners using a dry filter are effective to a certain degree against particulate matter such as dust, dust, and pollen, they usually remove gaseous harmful substances such as formaldehyde, acetaldehyde, ammonia, and dioxin. It cannot be removed effectively.

また、ウイルスなどの極細微粒子の異物については、それを取り除くことができない場合が多いといった問題がある。つまり、異物除去可能性が除去対象である異物のサイズに依存するという難点がある。また、そのような乾式フィルタにおいては、通常、目詰まりにより異物除去能力が短期間の内に低下するため、フィルタを頻繁に清掃したり、頻繁に取り替えたりする必要があり、保守が煩雑であるとともに、ランニングコストが高くなるといった問題がある。   In addition, there is a problem that extra fine particles such as viruses are often unable to be removed. That is, there is a difficulty that the possibility of removing foreign matter depends on the size of the foreign matter to be removed. Further, in such a dry filter, since the foreign substance removing ability usually decreases within a short time due to clogging, it is necessary to frequently clean the filter or replace it, and maintenance is complicated. At the same time, there is a problem that the running cost becomes high.

本発明はかかる従来技術の課題に鑑みなされたものであって、粒子サイズおよび状態に拘わらず空気中の異物および有害物質を有効に取り除くことができるとともに、ランニングコストが低コストでありかつ保守が容易な空気洗浄装置を提供することを目的としている。   The present invention has been made in view of the problems of the prior art, and can effectively remove foreign substances and harmful substances in the air regardless of the particle size and state, has a low running cost, and can be maintained. An object is to provide an easy air cleaning device.

A water flow-down device and a water recovery mechanism for returning water from the water flow-down device to the tank, and the air to be cleaned is passed through the water flowed down by the water flow-down device and washed. To do.

本発明の空気洗浄装置においては、前記水流下器がメッシュサイズの異なる２枚の網板を重ね合わせてなるものであるのが好ましい。   In the air cleaning apparatus of the present invention, it is preferable that the water flow down device is formed by overlapping two mesh plates having different mesh sizes.

また、本発明の空気洗浄装置においては、前記水流下器が水返し材を有してなるのが好ましい。   Moreover, in the air cleaning apparatus of this invention, it is preferable that the said water flow down device has a water return material.

本発明によれば、メンテナンスの簡素化およびランニングコストの低減を図りながら、室内の空気浄化がなし得るという優れた効果が得られる。   According to the present invention, it is possible to obtain an excellent effect of purifying indoor air while simplifying maintenance and reducing running costs.

以下、添付図面を参照しながら本発明を実施形態に基づいて説明するが、本発明はかかる実施形態のみに限定されるものではない。   Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.

図１および図２に、本発明の一実施形態に係る空気洗浄装置を模式的に示す。   1 and 2 schematically show an air cleaning device according to an embodiment of the present invention.

空気洗浄装置１は、図１および図２に示すように、装置１下部に配置され、空気洗浄用の水Ｗを貯留するタンク２と、タンク２内の水Ｗを装置１上部まで揚水するポンプ３と、洗浄される空気を送風するファン４と、ポンプ３により装置１上部まで揚水された水Ｗを、ファン４により送風される空気を洗浄するのに適した態様で流下させる水流下器５と、水流下器５により装置１下部まで流下された水Ｗをタンク２に戻すよう回収する水回収機構６とを主要構成要素として備えてなるものとされる。   As shown in FIGS. 1 and 2, the air cleaning device 1 is disposed at the lower portion of the device 1, and a tank 2 that stores water W for air cleaning, and a pump that pumps the water W in the tank 2 to the upper portion of the device 1. 3, a fan 4 that blows air to be cleaned, and a water flow down device 5 that causes water W pumped up to the upper part of the apparatus 1 by the pump 3 to flow down in a mode suitable for cleaning the air blown by the fan 4. And a water recovery mechanism 6 that recovers the water W that has flowed down to the lower part of the apparatus 1 by the water flow down device 5 so as to return it to the tank 2 as a main component.

また、水流下器５の上方には、ポンプ３により揚水された水Ｗを水流下器５に供給する水供給器１１が設けられるものとされる。   In addition, a water supply device 11 that supplies water W pumped by the pump 3 to the water flow down device 5 is provided above the water flow down device 5.

ここで、ファン４により送風される空気は、装置１後面に設けられる空気取り入れ口７から埃取り用のフィルタ８を介して装置１内に取り入れられる際に水流下器５を通過し、その後、装置１上部前面に設けられる空気吹き出し口９から装置１外部に送出される。   Here, the air blown by the fan 4 passes through the water flow down device 5 when being taken into the device 1 from the air intake port 7 provided on the rear surface of the device 1 via the filter 8 for dust removal, It is sent out of the apparatus 1 from an air outlet 9 provided on the upper front surface of the apparatus 1.

また、図２に示すように、水供給器１１は、水流下器５に上方から水Ｗを漏斗式に注ぐものとして構成されており、ポンプ３により揚水された水Ｗを一時的に保持する管状のバッファ室１２と、バッファ室１２の下面に所定間隔で設けられる水供給孔１３とを有してなるものとされる。また、バッファ室１２においてオーバーフローした水Ｗはドレンパイプ１４を介してタンク２に戻される。   Further, as shown in FIG. 2, the water supply device 11 is configured to pour water W into the water flow down device 5 from above, and temporarily holds the water W pumped by the pump 3. A tubular buffer chamber 12 and water supply holes 13 provided at predetermined intervals on the lower surface of the buffer chamber 12 are provided. Further, the water W overflowed in the buffer chamber 12 is returned to the tank 2 through the drain pipe 14.

図３および図４に示すように、水流下器５は、所定メッシュサイズの例えば樹脂からなる２枚の網板２１（２１Ａ、２１Ｂ）をフレーム２２に重ね合わせて貼り付けたものとして構成されており、網板２１Ａ、２１Ｂのメッシュを伝わらせながら水供給器１１により上方から注がれる水Ｗを流下させる。   As shown in FIG. 3 and FIG. 4, the water flow down device 5 is configured such that two mesh plates 21 (21A, 21B) made of, for example, resin having a predetermined mesh size are overlapped and attached to the frame 22. The water W poured from above is caused to flow down by the water supply device 11 while passing through the meshes of the mesh plates 21A and 21B.

また、図５に示すように、網板２１Ａ、２１Ｂは、メッシュサイズが、例えば３．５×３．５（ｍｍ）と５．０×５．０（ｍｍ）の２種類、というように互いに異なるものに設定されている。これにより、メッシュに水膜が形成されるのが防止されて、水Ｗをスムーズに流下させることが可能となるとともに、ファン４による送風負荷を低減させることが可能となる。   Further, as shown in FIG. 5, the mesh plates 21A and 21B have two kinds of mesh sizes, for example, two types of 3.5 × 3.5 (mm) and 5.0 × 5.0 (mm). It is set to something different. Thereby, the formation of a water film on the mesh is prevented, and the water W can flow smoothly, and the blowing load by the fan 4 can be reduced.

ここで、フレーム２２は、網板２１Ａ、２１Ｂを全体として鉛直に立てた状態で保持する一方で、図３に示すように、網板２１Ａ、２１Ｂの上端から所定幅の部分（以下、上端部という）２３を斜めに折り曲げた状態で保持するように、その上部に段差Ｈ１が設けられたものとされる。すなわち、斜めに曲げられた網板２１Ａ、２１Ｂの上端部２３に上方から水Ｗを注ぐものとすることによって、水供給器１１により注がれる水のほとんど全てを、網板２１Ａ、２１Ｂのメッシュを伝わらせて流下させることが可能となる。   Here, the frame 22 holds the net plates 21A and 21B as a whole in a vertically standing state. On the other hand, as shown in FIG. 3, a portion having a predetermined width from the upper end of the net plates 21A and 21B (hereinafter referred to as the upper end portion). It is assumed that a step H1 is provided on the upper part so that 23 is held obliquely. That is, by pouring water W from above onto the upper end portions 23 of the mesh plates 21A and 21B bent obliquely, almost all of the water poured by the water feeder 11 is transmitted through the mesh of the mesh plates 21A and 21B. It is possible to flow down.

また、フレーム２２の装置１裏面側には、水供給器１１により注がれる水Ｗが空気取り入れ口７からこぼれるのを防止するための水返し材２４が所定間隔で平行に配設されるものとされる。ここで、水返し材２４の上辺は、図３に示すように、上部から垂れてくる水を受けつつ、空気の流通路を確保するように斜め前、つまり装置１後側に突き出されたポケット部２４ａを構成するよう形成されている。   Further, on the back side of the device 1 of the frame 22, water return members 24 for preventing water W poured by the water supply device 11 from spilling from the air intake 7 are arranged in parallel at predetermined intervals. It is said. Here, as shown in FIG. 3, the upper side of the water return member 24 is a pocket protruding obliquely forward, that is, rearward of the apparatus 1 so as to secure an air flow passage while receiving water dripping from the upper part. It is formed so as to constitute part 24a.

しかして、空気洗浄装置１においては、空気取り入れ口７から装置１内部に取り入れられる空気が水流下器５を通過するに際し、網板２１のメッシュを伝わりながら流下する水Ｗと接触する。これによって、空気中に含まれる塵、埃、花粉、ウイルスといった粒子状の異物がそのサイズに拘わらず取り除かれるとともに、シックハウス症候群の元凶とされるホルムアルデヒドおよびアセトアルデヒド（たばこの煙）、ＮＯ２（自動車の排気ガス、工場の煤煙）、ＳＯ２（自動車の排気ガス）、アンモニア（ペットのにおい、たばこの煙）、ダイオキシンといった水溶性気体からなる有害物質（一般的な有害物質はほとんど全てが水溶性である）が取り除かれる。 Thus, in the air cleaning device 1, when the air taken into the device 1 from the air intake 7 passes through the water flow down device 5, it comes into contact with the water W that flows down along the mesh of the mesh plate 21. As a result, particulate foreign matters such as dust, dust, pollen and viruses contained in the air are removed regardless of the size, and formaldehyde and acetaldehyde (cigarette smoke), NO 2 (automobile), which are the main causes of sick house syndrome. Exhaust gas, factory smoke), SO 2 (automobile exhaust), ammonia (pet smell, cigarette smoke), dioxins and other hazardous substances (generally harmful substances are almost all water-soluble) Is removed.

また、水流下器５は、メッシュサイズが互いに異なる２枚の網板２１Ａ、２１Ｂを重ね合わせたものとして構成されているため、網板２１Ａ、２１Ｂのメッシュを伝わりながら流下する水Ｗが、メッシュに膜を形成することなくスムーズに流下していく。これにより、空気と接触する水Ｗがスムーズに交換され、高度の洗浄効率を達成することが可能となる。また、ファン４の送風負荷が軽減されて、消費電力の増大が抑えられる。   Moreover, since the water flow down device 5 is configured by superimposing two mesh plates 21A and 21B having different mesh sizes, the water W flowing down while passing through the meshes of the mesh plates 21A and 21B is meshed. It flows down smoothly without forming a film. As a result, the water W in contact with the air is smoothly exchanged, and a high cleaning efficiency can be achieved. Moreover, the ventilation load of the fan 4 is reduced and the increase in power consumption is suppressed.

その上、水Ｗの流れにより空気を洗浄するため、マイナスイオンが空気中に大量に放出される（滝壺効果）。これにより、室内環境が清涼感あふれるものになるとともに、健康を増進させるといった効果も期待できる。   In addition, since the air is washed by the flow of water W, a large amount of negative ions is released into the air (waterfall effect). As a result, the indoor environment is filled with a refreshing feeling and an effect of improving health can be expected.

また、洗浄用の水Ｗとしては水道水が利用でき（タンク２内の水を最短で２，３日おきに取り替えればよい）、実質、ランニングコストは、ポンプ３およびファン４の消費電力に相当するもののみであるため、ランニングコストを極めて安価（試作機において、約２円毎時）に抑えることが可能となる。   Further, tap water can be used as the cleaning water W (the water in the tank 2 may be replaced every few days at the shortest), and the running cost is substantially the power consumption of the pump 3 and the fan 4. Since it is only the equivalent, the running cost can be kept extremely low (about 2 yen per hour in the prototype).

また、タンク２内に、内容物を凍結させたアイスパック３１を入れるとともに、装置１下部と上部とを仕切る仕切り板３２に通風用のスリット（不図示である）などを形成することによって、冷気を室内に送風することも可能となり、冷房効果も得られる。   In addition, an ice pack 31 in which the contents are frozen is placed in the tank 2, and a ventilation slit (not shown) is formed in the partition plate 32 that partitions the lower portion and the upper portion of the apparatus 1. Can be blown into the room, and a cooling effect can be obtained.

本発明は、室内外の空気を洗浄し、清浄化する場合に適用できる。   The present invention can be applied to the case where indoor and outdoor air is washed and cleaned.
