Description

技術分野
本発明は、ビルディング等に据え付けられた空気調和装置等に使用されるエアーフィルターに関するものである。
背景技術
従来、この種の空調用エアーフィルターとして、片面にエアー流入口を、反対面にエアー流出口をそれぞれ開口してなる本体ボックスを作り、この本体ボックス内のエアー流入口とエアー流出口との間に、フィルター濾材をジグザグ状に配して接着剤で一体的に貼り付けたものがある。また、最近では、本体ボックス内にフィルター濾材のみを直接に張り付けるに代えて、フィルター濾材の外周をフィルター枠で囲む複数枚のフィルター本体を作り、この複数枚のフィルター本体を本体ボックス内にジグザグ状に配置するというものもある。
しかるに、前者のように本体ボックスにフィルター濾材が分離不可能に一体接合されている上記空調用エアーフィルターでは、単に１回の使用のみで廃棄処分されており、つまり使い捨てタイプであって、ゴミ発生の増大を招くばかりか、不経済極まりなかった。
後者のようにフィルター濾材の外周をフィルター枠で囲むフィルター本体を作り、このフィルター本体を本体ボックス内に取り外し可能に収納配備すると、本体ボックスとフィルター本体とが分離可能であるため、フィルター本体のみの洗浄や交換を可能にして省資源化、ゴミ減量化を図れて有利である。
しかしながら、このようにボックス本体から取り出し可能なフィルター本体において、フィルター枠の内部とフィルター濾材の外周端との間に隙間があると、この隙間からエアーが濾過されないまま漏れてエアーの濾過効率が低下するため、フィルター枠の内周に対してフィルター濾材の外周端を接着剤で一体的に貼り付けることにより前記エアー漏れを防止している。このため、フィルター枠とフィルター濾材とを完全に分離することができず、フィルター濾材のみの交換やフィルター枠のリサイクルを困難ないし不可能にし、またフィルター濾材を清掃ないし洗浄するにしてもフィルター枠が付いたままであるため十分に清掃ないし洗浄することができなかった。
そこで、本発明の目的は、フィルター濾材とフィルター枠よりなるフィルター本体のみの清掃ないし洗浄や交換を可能にして省資源化、ゴミ減量化及びコストダウンを図れる空調用エアーフィルターを提供することにある。また本発明の目的は、フィルター濾材のみの清掃ないし洗浄や交換、フィルター枠のリサイクルの簡易化を図れる空調用エアーフィルターを提供することにある。
発明の開示
本発明の空調用エアーフィルターは、片面にエアー流入口を、反対面にエアー流出口をそれぞれ開口してなる本体ボックスと、この本体ボックス内のエアー流入口とエアー流出口との間にジグザグ状にかつ出し入れ可能に収納されるフィルター本体とを備える。そして、前記フィルター本体は、一対の分割枠体を分離可能に突き合わせ接合することにより、断面溝形枠材を四角形状に枠組みしてなるフィルター枠内に、多数の山部が連なる蛇腹状のフィルター濾材を取り外し可能に嵌め込んでいる。前記フィルター濾材は、山部連なり方向と直交する幅方向の両端部の表裏両面もしくはその片面に、隣接する山部同士間の谷部を埋めるシール材を山部連なり方向にわたって一体に形成しており、そのシール材によって前記断面溝形枠材の溝内とこれに嵌合される前記幅方向両端部との間の隙間が塞がれるようにしたものである。
このように構成された空調用エアーフィルターによれば、フィルター本体が本体ボックスに対し出し入れ可能に収納されるので、フィルター本体を本体ボックスから取り出して簡単に清掃ないし洗浄や交換を行ない得て再使用することができる。
上記蛇腹状のフィルター濾材の幅方向両端部と断面溝形枠材の溝内との間の隙間を塞ぐシール材は、フィルター濾材側のみに一体に形成されていて、断面溝形枠材の溝内面とは密接しても分離できる接合関係にある。したがって、フィルター濾材の幅方向両端部と断面溝形枠材の溝内との間の隙間からエアーが濾過されないまま漏れるを防止でき、しかも蛇腹状のフィルター濾材は断面溝形枠材の溝から容易に取り出すことができ、フィルター濾材のみの清掃ないし洗浄や取り替えを可能にし、また耐用年数の過ぎたフィルター枠のみのリサイクルを可能にする。
シール材がフィルター濾材に一体に形成されていることにより、フィルター濾材の幅方向両端部を断面溝形枠材の溝内に嵌め込むと同時に両者間の隙間をシールする状態を得ることができ、その嵌め込みとは別にシール作業する必要がなくなる。したがって、フィルター本体の組立て作業、とくにフィルター濾材のみの清掃ないし洗浄時や取り替え時におけるフィルター枠に対するフィルター濾材の取り付け、取り外し作業が能率的に行える。
また、本発明の空調用エアーフィルターにおける上記シール材は、フィルター濾材の幅方向両端部の谷部の深さよりも少し高くなるよう形成してあるものである。
このように形成されたシール材によれば、フィルター枠の断面溝形枠材の溝幅とフィルター濾材の幅方向両端部の山部の高さ寸法との間に少々の寸法ばらつきがある場合も、フィルター濾材の幅方向両端部と断面溝形枠材の溝内との間の隙間を確実にシールすることができる。
この場合、シール材の素材としてはポリプロピレン系樹脂を用いると、適度の弾性があるため断面溝形枠材の溝内に対し隙間なく密着させることができてシール効果を高め、また耐候性に優れ、さらにフィルター濾材に対する接着性にも優れて容易に剥がれるようなことがなくて有利である。
フィルター濾材の材料としてはポリオレフィン系繊維を用いると、洗浄によく耐え、また付着ゴミ粒子を洗い落し易い。
発明を実施するための最良の形態
図１及び図２において、この空調用エアーフィルターは、本体ボックス１と、この本体ボックス１内に出し入れ可能に収納する複数枚のフィルター本体２とを備える。本体ボックス１は正面側にエアー流入口３を、背面側にエアー流出口４をそれぞれ開口し、上面側は天板５で、底面側は底板６で、左右側面側は左右側板７，８でそれぞれ塞いでなる。天板５、底板６及び左右側板７，８には鋼板等の金属板、合成樹脂成形体あるいは木材を使用できる。
図３及び図４に示すように、フィルター本体２は、四角形枠状のフィルター枠９にフィルター濾材１０を嵌め込んでなる。フィルター枠９はＡＢＳ樹脂等プラスチック製の断面溝形枠材１１を四角形状に枠組みしてなる。断面溝形枠材１１は左右の分割枠１１１，１１２を分離可能に突き合わせ結合するものとしてあり、各分割枠１１１，１１２は断面Ｌ形の上下枠１１１ａ，１１２ａ，１１１ｂ，１１２ｂと前後枠１１１ｃ，１１２ｃ，１１１ｄ，１１２ｄとを有する四角形枠状に形成される。左右の分割枠１１１，１１２を突き合わせることにより上下枠１１１ａ，１１２ａ，１１１ｂ，１１２ｂ及び前後枠１１１ｃ，１１２ｃ，１１１ｄ，１１２ｄはそれぞれ断面溝形を呈する。
フィルター濾材１０の素材としては合成繊維を使用し、合成繊維のうちでも特に洗浄によく耐え、また付着ゴミ粒子を洗い落し易いポリエチレン繊維、ポリプロピレン繊維等のポリオレフィン系繊維が使用される。ポリオレフィン系繊維を不織布あるいは編物、織物などの布帛にし、この布帛を図４に示すごとく多数の山部１０ａが連なる蛇腹状に折り曲げることによりフィルター濾材１０が構成される。
この蛇腹状のフィルター濾材１０の山部連なり方向と直交する幅方向の両端部の表裏両面には、ポリプロピレン系樹脂からなるシール材１２を山部連なり方向にわたって隣接する山部１０ａ，１０ａ同士間の谷部１０ｂを埋めるよう塗布し乾燥固化することにより一体に形成する。
そして、このフィルター濾材１０は、図５及び図７に示すように、上記断面溝形枠材１１の左右の分割枠１１１，１１２同士間に取り外し可能に挟持される。その際、フィルター濾材１０の幅方向両端部が断面溝形枠材１１の溝内に嵌合するとともに、その幅方向両端部と断面溝形枠材１１の溝内との間の隙間がシール材１２で塞がれる状態が得られる。
この場合、フィルター枠９の断面溝形枠材１１の溝幅Ｗ（図７参照）とフィルター濾材１０の幅方向両端部の山部１０ａの高さ寸法Ｈ（図７参照）との間に少々の寸法ばらつきがある場合も、フィルター濾材１０の幅方向両端部と断面溝形枠材１１の溝内との間の隙間を確実にシールすることができるように、上記シール材１２は、フィルター濾材１０の谷部１０ｂの深さＤ（図７参照）よりも少し高くなるよう形成することが好ましい。
フィルター濾材１０は蛇腹状に折り曲げることにより、一定の縦横サイズのフィルター濾材１０に対する空気の接触面積をできだけ増やすことができるので通気抵抗を低減させる効果がある。
上記フィルター枠９において、左右の分割枠１１１，１１２を分離可能に結合する手段としては、図４に示すように、左右の分割枠１１１，１１２の一方の数箇所に係合突起１３を一体に突設し、他方に該係合突起１３に対応する係合孔１４をあけて、係合突起１３を係合孔１４に係脱可能に弾性係合させるという手段を採用する（図９参照）。また、フィルター枠９内で蛇腹状のフィルター濾材１０が伸縮方向に移動することのないように、左右の分割枠１１１，１１２の各内面の数箇所には濾材保持突起１１５を一体に突設し、この濾材保持突起１１５にフィルター濾材１０の隣り合う山部１０ａ，１０ａの山頂部同士間を係入させる（図９参照）。
このように分割枠１１１，１１２に一体に形成した係合突起１３と係合孔１４との係合でもって左右の分割枠１１１，１１２同士を分離可能に結合し、また同じく分割枠１１１，１１２に一体に形成した濾材保持突起１１５でフィルター濾材１０の伸縮方向移動を規制することにより、フィルター枠９とは別体のそれら結合部材や移動規制部材を特別に用意する必要が無くなり、それだけ部材点数や組立工数の減少を図れるばかりか、フィルター枠９の廃棄にあたってリサイクルする場合も異質部材の分別作業を省略できるため、それだけリサイクルしやすくなる。なお、図４に示す左右の分割枠１１１，１１２は共に同じ形状に形成され、互いに上下逆様にして突き合わせることができるようにしてある。
フィルター本体２は、図１及び図６に示すごとく本体ボックス１内に左右方向にジグザグ状に配されるように本体ボックス１の正面側から出し入れ可能に装着される。フィルター本体２をジグザグ状に配置するのは、一定枚数のフィルター本体２に対する空気の接触面積をできる限り増大して通気抵抗を低減し空気の濾過処理量を高めるためである。
図２及び図５に示すように、本体ボックス１の天板５の内面及び底板６の内面には断面凸形のガイドレール１５とこのガイドレール１５の左右両側に平行に配されるガードレール１６，１６とがそれぞれジグザグ状に配置固定される一方、各フィルター本体２のフィルター枠９の上枠１１１ａ，１１２ａの上端面及び下枠１１１ｂ，１１２ｂの下端面に、ガイドレール１５にスライド自在に嵌合する断面凸形のスライド溝１７がそれぞれ前後方向全長にわたって設けられる。左右のガードレール１５，１５の各内側の前後には係合突片１８を水平に突設する一方、各フィルター本体２のフィルター枠９の上枠１１１ａ，１１２ａの両側面及び下枠１１１ｂ，１１２ｂの両側面に、係合突片１８にスライド自在に嵌合する係合溝１９がそれぞれ前後方向全長にわたって設けられる。
かくして、フィルター本体２は上下のスライド溝１７を本体ボックス１内の上下に対向するガードレール１６，１６間のガイドレール１５に摺動させることにより本体ボックス１内に脱線することなく前後斜め方向に円滑に出し入れすることができる。また、本体ボックス１の天板５及び底板６の各内面とフィルター本体２の上枠１１１ａ，１１２ａ及び下枠１１１ｂ，１１２ｂとの重合面間の隙間は、ガードレール１６，１６、及びガイドレール１５とスライド溝１７との嵌合により迷路となるため、エアー流入口３からのエアーが濾過されないままエアー流出口４側へ漏れるのをできる限り防止できる。
図２及び図６に示すように、本体ボックス１の背面側のエアー流出口４内には断面溝形の後ろ縦桟２０がガイドレール１５の後端位置に対応すべく左右方向に所定間隔をおいて配置固定され、この後ろ縦桟２０の溝２０ａ内でフィルター本体２の後枠１１１ｄ，１１２ｄを受け入れるようにしている。そして本体ボックス１の正面側のエアー流入口３内には、断面溝形の前縦桟２１がガイドレール１５の前端位置に対応すべく左右方向に所定間隔をおいて並ぶように上下の横桟２２，２３でつないでなる押さえ枠体２４が嵌め込み自在とされている。フィルター本体２を本体ボックス１内に差し込み収納した後、押さえ枠体２４を本体ボックス１の正面側に嵌め込み固定すると、前縦桟２１の溝２１ａ内でフィルター本体２の前枠１１１ｃ，１１２ｃが押されてフィルター本体２全体が後ろ縦桟２０に対し押しつけられる。
図６に示すように、後ろ縦桟２０及び前縦桟２１の各溝２０ａ，２１ａにはスポンジゴム等からなるエアー漏れ防止用のクッション材２５を内在させることにより、隣り合うフィルター本体２の前枠１１１ｃ，１１２ｃ同士の合掌部分、及び後枠１１１ｄ，１１２ｄ同士の合掌部分から流入空気が濾過されないままエアー流出口４側へ漏れるのを防止している。
上記構成の空調用エアーフィルターにおいて、エアー流入口３から流入する空気はフィルター本体２のフィルター濾材１０の濾過作用により清浄化されてエアー流出口４から流出する。その際、図６のようにフィルター濾材１０の幅方向両端部とフィルター枠９の断面溝形枠材１１の溝内との間の隙間はシール材１２によって塞がれているので、フィルター濾材１０の幅方向両端部と断面溝形枠材１１の溝内との間の隙間からエアーが濾過されないまま漏れるのを防止することができる。したがって、この空調用エアーフィルターによれば、空気清浄の効率を高めることができる。
使用に伴いフィルター本体２が破損した場合は、本体ボックス１はそのまま使用し、フィルター本体２のみを本体ボックス１から取り出して新規なものと取り替えればよく、この取り替えは簡単に行える。
またフィルター濾材１０のみが汚れたり、破損した場合は、フィルター枠９の断面溝形枠材１１の溝からフィルター濾材１０を取り外すことができてその清掃洗浄や取り替えを容易に行うことができる。フィルター濾材１０は洗浄後、再度フィルター枠９内に嵌め込み直すことで再使用できる。
上記実施例ではフィルター濾材１０の幅方向両端部の表裏両面にシール材１２をそれぞれ一体に形成するが、これに代えてシール材１２はフィルター濾材１０の幅方向両端部の表面側のみまたは裏面側のみに一体に形成することもできる。また、図１０に示すように、フィルター濾材１０のシール材１２として空気を通さないように形成された不織布やその他のプラスチックシート材などを用い、これをフィルター濾材１０の幅方向端面に一体的に貼り付けて表裏両面の谷部１０ｂもしくはその片面の谷部１０ｂを塞ぐものであってもよい。
なお、上記フィルター枠９の四角形状の断面溝形枠材１１は、上記実施例のように左右に二分割可能に形成されるものに限定されるものではない。

BACKGROUND ART Conventionally, as this type of air filter for air conditioning, a body box is formed by opening an air inlet on one side and an air outlet on the opposite side, and an air inlet and an air outlet in the body box are provided. Among them, there is a filter filter medium arranged in a zigzag shape and attached integrally with an adhesive. Recently, instead of directly attaching only the filter medium in the main body box, a plurality of filter bodies are formed by surrounding the outer periphery of the filter medium with a filter frame, and the plurality of filter bodies are zigzag in the main body box. Some are arranged in a shape.
However, as in the former case, the air filter for air conditioning in which the filter medium is integrally joined to the main body box in a non-separable manner is disposed of only by one use. It was not only extremely uneconomical.
If the filter body surrounding the outer periphery of the filter medium with a filter frame is made like the latter and this filter body is detachably stored in the body box, the body box and filter body can be separated, so only the filter body can be separated. This is advantageous because it can be cleaned and replaced to save resources and reduce waste.
However, in the filter body that can be removed from the box body in this way, if there is a gap between the inside of the filter frame and the outer peripheral edge of the filter medium, the air leaks without being filtered from this gap and the air filtration efficiency decreases. Therefore, the air leakage is prevented by integrally bonding the outer peripheral end of the filter medium with an adhesive to the inner periphery of the filter frame. For this reason, the filter frame and the filter medium cannot be completely separated, making it difficult or impossible to replace only the filter medium or recycling the filter frame. It was still attached and could not be cleaned or washed sufficiently.
Accordingly, an object of the present invention is to provide an air filter for air conditioning that enables cleaning, washing, and replacement of only a filter body including a filter medium and a filter frame, thereby saving resources, reducing dust, and reducing costs. . Another object of the present invention is to provide an air filter for air conditioning capable of simplifying cleaning, washing or replacement of only the filter medium and recycling of the filter frame.
DISCLOSURE OF THE INVENTION An air-conditioning air filter according to the present invention comprises a main body box having an air inlet on one side and an air outlet on the opposite side, and an air inlet and an air outlet in the main body box. And a filter main body that is housed in a zigzag shape and is detachable. The filter main body has a bellows-like filter in which a large number of mountain portions are connected in a filter frame formed by framing a cross-sectional groove-shaped frame material by butt-joining a pair of divided frame bodies in a separable manner. The filter medium is detachably fitted. The filter medium is formed integrally on the front and back surfaces of both ends in the width direction perpendicular to the ridge line direction or on one side thereof with a sealing material filling the valleys between adjacent ridge parts over the ridge line direction. The sealing material closes the gap between the groove of the cross-sectional groove frame and the both ends in the width direction fitted to the groove.
According to the air filter for air conditioning configured in this way, the filter body is stored in a removable manner with respect to the main body box, so the filter main body can be removed from the main body box and easily cleaned, washed or replaced for reuse. can do.
The sealing material that closes the gap between the widthwise ends of the bellows-like filter medium and the groove of the cross-sectional groove frame material is formed integrally only on the filter medium side, and the groove of the cross-sectional groove frame material It is in a joint relationship that can be separated from the inner surface even when in close contact. Therefore, air can be prevented from leaking without being filtered from the gap between the both ends in the width direction of the filter medium and the groove of the cross-sectional grooved frame material, and the bellows-shaped filter medium can be easily removed from the groove of the cross-sectional grooved frame material. The filter media can be cleaned, washed or replaced, and only the filter frame that has passed its service life can be recycled.
By forming the sealing material integrally with the filter medium, it is possible to obtain a state in which both ends in the width direction of the filter medium are fitted into the grooves of the cross-sectional groove frame material and at the same time the gap between the two is sealed. There is no need to perform sealing work separately from the fitting. Therefore, the assembling work of the filter body, in particular, the attaching / detaching operation of the filter medium to / from the filter frame at the time of cleaning or washing only the filter medium or replacement can be efficiently performed.
Moreover, the said sealing material in the air filter for air conditioning of this invention is formed so that it may become a little higher than the depth of the trough part of the width direction both ends of a filter medium.
According to the sealing material formed in this way, there may be a slight dimensional variation between the groove width of the cross-sectional groove frame material of the filter frame and the height dimension of the crests at both ends in the width direction of the filter medium. The gap between the both ends in the width direction of the filter medium and the inside of the groove of the cross-sectional groove frame can be reliably sealed.
In this case, if polypropylene resin is used as the material for the sealing material, it has moderate elasticity, so that it can be tightly adhered to the inside of the groove of the cross-sectional grooved frame material, improving the sealing effect, and excellent in weather resistance. Furthermore, it is advantageous in that it is excellent in adhesion to the filter medium and does not easily peel off.
When a polyolefin fiber is used as a material for the filter medium, it can withstand washing well and easily removes adhering dust particles.
BEST MODE FOR CARRYING OUT THE INVENTION In FIGS. 1 and 2, the air filter for air conditioning includes a main body box 1 and a plurality of filter main bodies 2 that are housed in the main body box 1 so as to be able to be taken in and out. The main body box 1 has an air inlet 3 on the front side and an air outlet 4 on the back side. The top surface is a top plate 5, the bottom surface is a bottom plate 6, and the left and right side surfaces are left and right side plates 7 and 8. Each blockade. For the top plate 5, the bottom plate 6, and the left and right side plates 7, 8, a metal plate such as a steel plate, a synthetic resin molded body, or wood can be used.
As shown in FIGS. 3 and 4, the filter body 2 is formed by fitting a filter medium 10 into a filter frame 9 having a rectangular frame shape. The filter frame 9 is formed by forming a cross-sectional groove-shaped frame material 11 made of plastic such as ABS resin into a quadrangular shape. The cross-sectional groove-shaped frame member 11 is configured so that the left and right divided frames 111 and 112 are butt-coupled so as to be separable, and each divided frame 111 and 112 has an L-shaped upper and lower frames 111a, 112a, 111b and 112b and front and rear frames 111c, It is formed in a rectangular frame shape having 112c, 111d, and 112d. By matching the left and right divided frames 111 and 112, the upper and lower frames 111a, 112a, 111b, and 112b and the front and rear frames 111c, 112c, 111d, and 112d each have a cross-sectional groove shape.
Synthetic fibers are used as the material for the filter medium 10, and among the synthetic fibers, polyolefin fibers such as polyethylene fibers and polypropylene fibers that are particularly resistant to washing and easily wash off attached dust particles are used. The filter medium 10 is configured by making polyolefin fibers into a fabric such as a nonwoven fabric, a knitted fabric, or a fabric, and bending the fabric into a bellows shape in which a large number of peak portions 10a are continuous as shown in FIG.
On both the front and back surfaces of both end portions in the width direction perpendicular to the direction of the ridges of the bellows-shaped filter medium 10, a sealing material 12 made of polypropylene resin is provided between the ridges 10a, 10a adjacent to each other in the direction of the ridges. It forms so that it may be united by apply | coating so that the trough part 10b may be filled, and drying and solidifying.
The filter medium 10 is detachably sandwiched between the left and right divided frames 111 and 112 of the cross-sectional groove frame 11 as shown in FIGS. 5 and 7. At that time, both ends in the width direction of the filter medium 10 are fitted into the grooves of the cross-sectional groove frame material 11, and a gap between the both ends in the width direction and the grooves in the cross-sectional groove frame material 11 is a sealing material. A state of being blocked at 12 is obtained.
In this case, there is a little between the groove width W (see FIG. 7) of the cross-sectional groove-shaped frame member 11 of the filter frame 9 and the height dimension H (see FIG. 7) of the crests 10a at both ends in the width direction of the filter medium 10. In order to ensure that the gap between the both ends in the width direction of the filter medium 10 and the inside of the groove of the cross-sectional grooved frame material 11 can be reliably sealed, It is preferable to form so as to be slightly higher than the depth D (see FIG. 7) of the ten valley portions 10b.
By folding the filter medium 10 into a bellows shape, the air contact area with respect to the filter medium 10 having a certain vertical and horizontal size can be increased as much as possible, so there is an effect of reducing the ventilation resistance.
In the filter frame 9, as means for detachably coupling the left and right divided frames 111, 112, as shown in FIG. 4, the engaging protrusions 13 are integrally formed at one of the left and right divided frames 111, 112. A means is employed in which a protrusion is provided, an engagement hole 14 corresponding to the engagement protrusion 13 is formed on the other side, and the engagement protrusion 13 is elastically engaged with the engagement hole 14 in a detachable manner (see FIG. 9). . Further, filter medium holding projections 115 are integrally projected at several positions on the inner surfaces of the left and right divided frames 111 and 112 so that the bellows-shaped filter medium 10 does not move in the expansion / contraction direction in the filter frame 9. Then, the peak portions of the adjacent peak portions 10a and 10a of the filter medium 10 are engaged with the filter medium holding projection 115 (see FIG. 9).
The left and right divided frames 111 and 112 are detachably coupled to each other by the engagement of the engaging projections 13 and the engaging holes 14 formed integrally with the divided frames 111 and 112 as described above. By restricting the movement of the filter medium 10 in the expansion / contraction direction by the filter medium holding protrusion 115 formed integrally with the filter frame 9, it is not necessary to prepare these connecting members and movement restriction members separately from the filter frame 9, and the number of members is accordingly increased. In addition, the number of assembly steps can be reduced, and when the filter frame 9 is recycled when it is discarded, the separation work of the foreign member can be omitted, so that it becomes easier to recycle. Note that the left and right divided frames 111 and 112 shown in FIG. 4 are both formed in the same shape, and can be abutted upside down.
As shown in FIGS. 1 and 6, the filter main body 2 is detachably mounted from the front side of the main body box 1 so as to be arranged in a zigzag shape in the left-right direction in the main body box 1. The reason why the filter main bodies 2 are arranged in a zigzag shape is to increase the contact area of the air to the fixed number of filter main bodies 2 as much as possible to reduce the airflow resistance and increase the air filtration processing amount.
As shown in FIGS. 2 and 5, a guide rail 15 having a convex cross section on the inner surface of the top plate 5 and the inner surface of the bottom plate 6 of the main body box 1 and guard rails 16 arranged in parallel on the left and right sides of the guide rail 15, 16 are arranged and fixed in a zigzag shape, and are slidably fitted to the guide rail 15 on the upper end surfaces of the upper frames 111a and 112a and the lower end surfaces of the lower frames 111b and 112b of the filter frame 9 of each filter body 2. The slide grooves 17 having a convex cross section are provided over the entire length in the front-rear direction. Engagement protrusions 18 are provided horizontally on the front and rear sides of the left and right guard rails 15 and 15, respectively, while the side surfaces of the upper frames 111a and 112a of the filter frame 9 of each filter body 2 and the lower frames 111b and 112b. Engaging grooves 19 slidably fitted to the engaging protrusions 18 are provided on both side surfaces over the entire length in the front-rear direction.
Thus, the filter main body 2 can be smoothly moved diagonally in the front-rear direction without derailing into the main body box 1 by sliding the upper and lower slide grooves 17 on the guide rails 15 between the guard rails 16, 16 facing the upper and lower sides in the main body box 1. Can be put in and out. Further, the gaps between the inner surfaces of the top plate 5 and the bottom plate 6 of the main body box 1 and the upper frames 111a and 112a and the lower frames 111b and 112b of the filter body 2 are separated from the guard rails 16 and 16 and the guide rail 15 with each other. Since it becomes a maze by fitting with the slide groove 17, it is possible to prevent the air from the air inlet 3 from leaking to the air outlet 4 side without being filtered.
As shown in FIGS. 2 and 6, a rear vertical rail 20 having a groove shape in the cross section is formed in the air outlet 4 on the back side of the body box 1 at a predetermined interval in the left-right direction so as to correspond to the rear end position of the guide rail 15. The rear frames 111d and 112d of the filter main body 2 are received in the groove 20a of the rear vertical beam 20. In the air inlet 3 on the front side of the main body box 1, the upper and lower horizontal beams are arranged so that the front vertical beam 21 having a groove shape is aligned at a predetermined interval in the left-right direction so as to correspond to the front end position of the guide rail 15. A holding frame 24 connected by 22 and 23 can be fitted freely. After the filter main body 2 is inserted and stored in the main body box 1, when the presser frame 24 is fitted and fixed to the front side of the main body box 1, the front frames 111 c and 112 c of the filter main body 2 are pressed in the groove 21 a of the front vertical rail 21. Thus, the entire filter body 2 is pressed against the rear vertical beam 20.
As shown in FIG. 6, each groove 20 a, 21 a of the rear vertical beam 20 and the front vertical beam 21 is provided with a cushion material 25 for preventing air leakage made of sponge rubber or the like so that the front of the adjacent filter main body 2 can be obtained. Inflow air is prevented from leaking to the air outlet 4 side without being filtered from the joint portion between the frames 111c and 112c and the joint portion between the rear frames 111d and 112d.
In the air filter for air conditioning having the above configuration, the air flowing in from the air inlet 3 is purified by the filtering action of the filter medium 10 of the filter body 2 and flows out from the air outlet 4. At this time, as shown in FIG. 6, the gap between the both ends in the width direction of the filter medium 10 and the groove of the cross-sectional groove-shaped frame material 11 of the filter frame 9 is closed by the sealing material 12. It is possible to prevent air from leaking through the gap between the both ends in the width direction and the inside of the groove of the cross-sectional grooved frame member 11 without being filtered. Therefore, according to the air filter for air conditioning, the efficiency of air purification can be increased.
When the filter main body 2 is damaged due to use, the main body box 1 can be used as it is, and only the filter main body 2 can be taken out from the main body box 1 and replaced with a new one. This replacement can be easily performed.
When only the filter medium 10 is soiled or damaged, the filter medium 10 can be removed from the groove of the cross-sectional groove-shaped frame 11 of the filter frame 9 and can be easily cleaned and replaced. The filter medium 10 can be reused by reinserting it into the filter frame 9 after washing.
In the above embodiment, the sealing material 12 is integrally formed on both the front and back surfaces of the both ends in the width direction of the filter medium 10, but instead of this, the sealing material 12 is only the front side or the back side of the both ends in the width direction of the filter medium 10. It is also possible to form a single body only. Further, as shown in FIG. 10, a non-woven fabric or other plastic sheet material formed so as not to allow air to pass is used as the sealing material 12 of the filter medium 10, and this is integrated with the end face in the width direction of the filter medium 10. It may be affixed to close the troughs 10b on both front and back surfaces or the troughs 10b on one side.
Note that the rectangular cross-sectional groove-shaped frame member 11 of the filter frame 9 is not limited to the one that can be divided into right and left as in the above-described embodiment.
