【発明の属する技術分野】
本発明は、エアフィルタの交換部構造及びエアフィルタの交換方法に関し、特に、専用のエアフィルタ交換口を形成することなく、有害物質の洩れを防止しながら、排気側又は給気側の開口部（本明細書において、「給排気口の開口部」と総称する。）を介してエアフィルタを交換することができるエアフィルタの交換部構造及びエアフィルタの交換方法に関するものである。
【０００２】
【従来の技術】
病院や生物・化学研究施設等のバイオハザードやケミカルハザード等についての対策が必要とされる施設に用いられる空調機には、清浄度を維持するために、集塵能力に優れるＨＥＰＡ等のエアフィルタが採用されている。
【０００３】
一方、病院や生物・化学研究施設等のバイオハザードやケミカルハザード等についての対策が必要とされる施設に用いられる濾過装置の使用済のエアフィルタを交換する際には、ハウジングに設けたエアフィルタ交換口にエアフィルタ収容袋を予め取り付けておき、このエアフィルタ交換口に取り付けられたエアフィルタ収容袋によって有害物質の洩れを完全に防止しながら、エアフィルタを交換するエアフィルタの交換部構造が提案され、実用化されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記の濾過装置のエアフィルタの交換部構造においては、エアフィルタ交換口をエアフィルタの吸い込み方向と直交するハウジングの側部に形成する必要があり、このため、床置き型や壁付け型の給排気口には実施できるとしても、例えば、天井埋め込み型の給排気口には実施することができないという問題があった。
【０００５】
本発明は、上記従来のエアフィルタの交換部構造の有する問題点に鑑み、専用のエアフィルタ交換口を形成することなく、有害物質の洩れを防止しながら、給排気口の開口部を介してエアフィルタを交換することができるエアフィルタの交換部構造及びエアフィルタの交換方法を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、本発明のエアフィルタの交換部構造は、天井埋め込み型の給排気口の天井面の開口部に給排気を行うグリル部を着脱可能に配設するとともに、ハウジングに装着されたエアフィルタを給排気口の開口部を介して交換するようにしたエアフィルタの交換部構造において、グリル部を取り外した給排気口の開口部に、周方向に複数の溝部を備えたエアフィルタ収容袋取付部を着脱可能に配設したことを特徴とする。
【０００７】
また、本発明のエアフィルタの交換方法は、天井埋め込み型の給排気口の天井面の開口部に給排気を行うグリル部を着脱可能に配設するとともに、ハウジングに装着されたエアフィルタを給排気口の開口部を介して交換するエアフィルタの交換方法であって、グリル部を取り外した給排気口の開口部に、周方向に複数の溝部を備えたエアフィルタ収容袋取付部を設けてフィルタ収容袋を取り付けるとともに、エアフィルタを取り外して該フィルタ収容袋内に収容した後、該フィルタ収容部分とフィルタ収容袋の残部との間を閉塞し、該閉塞部分を切断してフィルタ収容部分を分離除去し、次いで、交換用エアフィルタを収容したフィルタ収容袋を、エアフィルタ収容袋取付部に残ったフィルタ収容袋の残部を覆うようにエアフィルタ収容袋取付部に取り付け、該残部の閉塞部分を開いて、交換用エアフィルタをハウジング内に装着した後、フィルタ収容袋の残部をエアフィルタ収容袋取付部から取り外し、後から取り付けたフィルタ収容袋内に収容した後、該フィルタ収容袋をエアフィルタ収容袋取付部から取り外し、開口部からエアフィルタ収容袋取付部を取り外すとともに、開口部にグリル部を装着することを特徴とする。
【０００８】
上記エアフィルタの交換部構造及びエアフィルタの交換方法は、専用のエアフィルタ交換口を形成することなく、有害物質の洩れを防止しながら、給排気口の開口部を介してエアフィルタを簡易に交換することができる。
【０００９】
【発明の実施の形態】
以下、本発明のエアフィルタの交換方法の実施の形態を図面に基づいて説明する。
【００１０】
図１〜図５に、本発明のエアフィルタの交換部構造及びエアフィルタの交換方法の１実施例を示す。
【００１１】
このエアフィルタの交換部構造は、例えば、病院や生物・化学研究施設等のバイオハザードやケミカルハザードについての中位又は低位レベルの対策が必要とされる施設に用いられる天井埋め込み型の給排気口に適用し、ハウジング１に装着されたエアフィルタ２を給排気口（本実施例においては排気側。空調機の形式等によって給気側の場合もあり、これを排除するものではない。）の開口部３を介して交換することができるようにしたもので、給排気口の開口部３にグリル部６を着脱可能に配設するとともに、グリル部６を取り外した給排気口の開口部３に、周方向に複数の溝部４１を備えたエアフィルタ収容袋取付部４を着脱可能に配設するようにしている。
【００１２】
そして、エアフィルタ２を交換するに際しては、給排気口の開口部３に筒状のエアフィルタ収容袋取付部４を装着し、エアフィルタ収容袋取付部４にフィルタ収容袋５を取り付けるとともに、エアフィルタ２をハウジング１から取り外し、フィルタ収容袋５内に収容した後、フィルタ収容部分５１とフィルタ収容袋の残部５２との間を閉塞し、閉塞部分５３を切断してフィルタ収容部分５１を分離除去する。

そして、図３（ａ）に示すように、フィルタ収容部分５１とフィルタ収容袋の残部５２との間を閉塞し、図３（ｂ）（ｃ）に示すように、閉塞部分５３を切断してフィルタ収容部分５１を分離除去する。
この場合、フィルタ収容袋５の閉塞は、切断後のフィルタ収容部分５１と残部５２とが両方とも閉塞されるように、上下２箇所をひも８で結んだり、所要幅広く溶着したりする。
【００１５】
そして、図３（ｄ）に示すように、交換用エアフィルタ２’を収容した別のフィルタ収容袋５’を、エアフィルタ収容袋取付部４に残ったフィルタ収容袋の残部５２を覆うようにエアフィルタ収容袋取付部４に取り付け、次に、図４（ａ）〜（ｃ）に示すように、残部５２の閉塞部分５３を開いて、交換用エアフィルタ２’をハウジング１内に装着する。
【００１６】
次に、図４（ｄ）〜図５（ａ）に示すように、フィルタ収容袋の残部５２をエアフィルタ収容袋取付部４から取り外し、後から取り付けたフィルタ収容袋５’内に収容した後、フィルタ収容袋５’をエアフィルタ収容袋取付部４から取り外す。
これにより、フィルタ収容袋の残部５２に付着した有害物質の洩れを防止しながら廃棄することができる。なお、フィルタ収容袋５’は、汚染されていない場合には、再利用することができる。
そして、図５（ｂ）に示すように、ハウジング１の開口部３からエアフィルタ収容袋取付部４を取り外すとともに、開口部３にグリル部６を装着して作業が終了する。
【００１７】
ところで、フィルタ収容袋５、５’は、通常は、その上から上記各操作を行うことができるように、柔軟性を備えたポリエチレン樹脂等の合成樹脂製袋を用いるようにするが、さらに、フィルタ収容袋５、５’に、手を嵌め入れることができる手袋部を形成したり、付属品としての手袋部を装着することができるようにすることにより、操作性を向上することができる。
【００１８】
本実施例のエアフィルタの交換部構造及びエアフィルタの交換方法は、ハウジング１の給排気口の開口部３に筒状のエアフィルタ収容袋取付部４を装着し、エアフィルタ収容袋取付部４にフィルタ収容袋５を取り付けるとともに、エアフィルタ２を取り外してフィルタ収容袋５内に収容した後、フィルタ収容部分５１とフィルタ収容袋の残部５２との間を閉塞し、閉塞部分５３を切断してフィルタ収容部分５１を分離除去し、次いで、交換用エアフィルタ２’を収容したフィルタ収容袋５’を、エアフィルタ収容袋取付部４に残ったフィルタ収容袋の残部５２を覆うようにエアフィルタ収容袋取付部４に取り付け、残部５２の閉塞部分５３を開いて、交換用エアフィルタ２’をハウジング１内に装着することから、専用のエアフィルタ交換口を形成することなく、有害物質の洩れを防止しながら、給排気口の開口部３を介してエアフィルタ２を交換することができる。
また、フィルタ収容袋の残部５２をエアフィルタ収容袋取付部４から取り外し、後から取り付けたフィルタ収容袋５’内に収容した後、フィルタ収容袋５’をエアフィルタ収容袋取付部４から取り外すことにより、フィルタ収容袋の残部５２に付着した有害物質の洩れを防止しながら廃棄することができる。
そして、このエアフィルタの交換部構造及びエアフィルタの交換方法によれば、専用のエアフィルタ交換口を形成することなく、有害物質の洩れを防止しながら、給排気口の開口部を介してエアフィルタを簡易に交換することができることから、特に、簡易気密型のものに好適に用いることができる。
【００１９】
以上、本発明のエアフィルタの交換部構造及びエアフィルタの交換方法の実施例を説明したが、本発明の構成は、上記実施例の構成に限定されるものではなく、例えば、エアフィルタ収容袋取付部を、開口部に予め形成するようにしておく等、その趣旨を逸脱しない範囲において適宜に変更することが可能である。
【００２０】
【発明の効果】
本発明のエアフィルタの交換部構造及びエアフィルタの交換方法によれば、専用のエアフィルタ交換口を形成することなく、有害物質の洩れを防止しながら、給排気口の開口部を介してエアフィルタを簡易に交換することができる。
そして、特に、給排気口の開口部にグリル部を着脱可能に配設するとともに、グリル部を取り外した給排気口の開口部に、周方向に複数の溝部を備えたエアフィルタ収容袋取付部を着脱可能に配設することにより、グリル部を取り付けるようにした給排気口の開口部近傍の構造を簡略化して、コストの低廉化を図ることができるとともに、デザインの自由度を高めることができる。

When the air filter 2 is replaced, a cylindrical air filter storage bag mounting portion 4 is mounted on the opening 3 of the air supply / exhaust port, and the filter storage bag 5 is mounted on the air filter storage bag mounting portion 4, After the filter 2 is removed from the housing 1 and accommodated in the filter housing bag 5, the space between the filter housing portion 51 and the remaining portion 52 of the filter housing bag is closed, and the closed portion 53 is cut to separate and remove the filter housing portion 51. To do.
Then, a filter housing bag 5 ′ that houses the replacement air filter 2 ′ is prepared separately, and the filter housing bag 5 ′ covers the remaining portion 52 of the filter housing bag remaining in the air filter housing bag mounting portion 4. Attached to the accommodation bag attaching portion 4, the closed portion 53 of the remaining portion 52 is opened, and the replacement air filter 2 ′ is mounted in the housing 1.
[0013]
The case where this air filter replacement method is implemented in a ceiling-embedded air supply / exhaust port will be specifically described.
As shown in FIGS. 1A to 1D, the grill 6 is removed from the opening 3 formed in the lower portion of the housing 1 of the air supply / exhaust port, and the cylindrical air filter housing bag mounting portion 4 is attached with a bolt or the like. As shown in FIGS. 2A to 2B, the filter housing bag 5 is attached to the air filter housing bag mounting portion 4.
As shown in FIG. 1 (c), the air filter storage bag mounting portion 4 includes a plurality of circumferential groove portions 41, and the mouth of the filter storage bag 5 covered by the groove portions 41 is fixed by an O-ring 7 or the like. It has become.
[0014]
Next, as shown in FIG. 2 (b), the air filter 2 is grasped and removed from the housing 1 together with the filter containing bag 5 from the outside of the filter containing bag 5, and as shown in FIG. House in bag 5.
Then, as shown in FIG. 3 (a), the space between the filter housing portion 51 and the remaining portion 52 of the filter housing bag is closed, and the closed portion 53 is cut as shown in FIGS. 3 (b) and 3 (c). The filter accommodating portion 51 is separated and removed.
In this case, the filter housing bag 5 is closed by tying the upper and lower two places with the string 8 so that both the cut filter housing portion 51 and the remaining portion 52 are closed, or welding as wide as required.
[0015]
And as shown in FIG.3 (d), another filter accommodation bag 5 'which accommodated replacement | exchange air filter 2' is covered so that the remaining part 52 of the filter accommodation bag remaining in the air filter accommodation bag attaching part 4 may be covered. It attaches to the air filter accommodation bag attaching part 4, and next, as shown to Fig.4 (a)-(c), the obstruction | occlusion part 53 of the remaining part 52 is opened, and replacement | exchange air filter 2 'is mounted in the housing 1. FIG. .
[0016]
Next, as shown in FIGS. 4D to 5A, after the remaining portion 52 of the filter storage bag is removed from the air filter storage bag mounting portion 4 and stored in the filter storage bag 5 ′ attached later. The filter housing bag 5 ′ is removed from the air filter housing bag mounting portion 4.
Thereby, it can discard, preventing the leakage of the harmful substance adhering to the remaining part 52 of a filter accommodation bag. The filter housing bag 5 ′ can be reused when it is not contaminated.
And as shown in FIG.5 (b), while removing the air filter accommodation bag attaching part 4 from the opening part 3 of the housing 1, the grill part 6 is attached to the opening part 3, and work is complete | finished.
