Description

本発明は、クリーンルームで使用するのに適したフィルタ装置に関する。   The present invention relates to a filter device suitable for use in a clean room.

従来、ＨＥＰＡフィルタを用いた一般的なクリーンルーム用のフィルタ装置は、ＨＥＰＡフィルタをケーシングの内部に配置して、ＨＥＰＡ ＢＯＸを構成している（例えば、特許文献１、２、３参照）。フィルタ装置は、コンベンショナルフロー（乱流方式）の場合、クリーンルームの天井に間隔を置いて配置して使用される。   Conventionally, a filter device for a general clean room using a HEPA filter has a HEPA BOX in which a HEPA filter is disposed inside a casing (see, for example, Patent Documents 1, 2, and 3). In the case of a conventional flow (turbulent flow system), the filter device is used by being spaced from the ceiling of the clean room.

しかしながら、特許文献１乃至３に記載のフィルタ装置では、フィルタの取付けにケーシングを必要としていたため、材料費が嵩み、コスト低減に限界があるという課題があった。また、フィルタ装置の設置の際、ケーシングの取付けに工数を要するため、取付けの作業時間が長くかかるという課題があった。フィルタの交換の際には、ケーシングを開いて中からフィルタを取り外す必要があるため、メンテナンスに手数がかかるという課題があった。さらに、特許文献１乃至３に記載のフィルタ装置では、フィルタを通して空気を吹き出すのみの構造のため、空気の拡散性が悪く、空調が十分に行われないという課題があった。   However, since the filter devices described in Patent Documents 1 to 3 require a casing for mounting the filter, there is a problem that the material cost increases and the cost reduction is limited. In addition, when installing the filter device, it takes a lot of man-hours to install the casing. When replacing the filter, it is necessary to open the casing and remove the filter from the inside. Furthermore, since the filter devices described in Patent Documents 1 to 3 have a structure in which air is only blown out through the filter, there is a problem that air diffusibility is poor and air conditioning is not sufficiently performed.

本発明は、このような課題に着目してなされたもので、材料費の低減および取付け作業時間の短縮を図ることができ、メンテナンスが容易で、かつ空調効果の高いフィルタ装置を提供することを目的としている。   The present invention has been made paying attention to such problems, and can provide a filter device that can reduce the material cost and shorten the installation work time, is easy to maintain, and has a high air conditioning effect. It is aimed.

上記目的を達成するために、本発明に係るフィルタ装置は、ルーバ部材を室内側に配置し、横方向に向いた天井面取付のダクト口に接続して使用されるフィルタ装置であって、枠状のホールディングフレームの内側にフィルタパックを配置して成るフィルタと、前記ダクト口に接続可能なダクト接続枠と、ダクト側支持部材と、前記ルーバ部材と、ルーバ側支持部材と、固定部材とを有し、前記ダクト接続枠は、前記フィルタより大きく前記フィルタの背面周囲に密着可能な背面対向面を有し、前記ダクト側支持部材は、断面がＬ字型のアングル材から成り、外側の一方の面の背面側支持面を上に向け、外側の他方の面のダクト側接触面を前記背面対向面に接触させて固定されており、前記ルーバ部材は、ルーバ保持枠の内側に風向調整用のルーバを設けて成り、前記ルーバ保持枠は前記フィルタより大きく前記フィルタの正面周囲に密着可能な正面対向面を有し、ルーバ側支持部材は、断面がＬ字型のアングル材から成り、外側の一方の面の正面側支持面を上に向け、外側の他方の面のルーバ側接触面を前記正面対向面に接触させて固定されており、前記固定部材は、前記背面側支持面と前記正面側支持面とで前記フィルタを支持した状態で、前記フィルタを前記ダクト接続枠と前記ルーバ部材との間に挟んで着脱可能に固定し、前記ダクト接続枠の背面対向面を前記フィルタの背面周囲に密着させ、前記ルーバ保持枠の正面対向面を前記フィルタの正面周囲に密着させていることを、特徴とする。
In order to achieve the above object, a filter device according to the present invention is a filter device that is used by arranging a louver member on the indoor side and connecting it to a duct-attached ceiling surface facing in the lateral direction.

次に、作用について説明する。
フィルタ装置１０は、例えばクリーンルーム生産装置機械室などに空気を吹き出すように、ルーバ部材１４を室内側に配置し、ダクト接続枠１２を天井面取付のダクト口１に接続して使用する。フィルタ１１は、ダクト口１から吹き出る空気を浄化し、クリーンな空気にして室内に供給する。ダクト接続枠１２の背面対向面１２ｃおよびルーバ保持枠１４ａの正面対向面１４ｅはそれぞれフィルタ１１の背面周囲および正面周囲に密着しており、ダクト内の浄化されていない空気が各部材の間から室内に漏れ出ることは防止されている。また、各ガスケット１７により、ダクト接続枠１２とフィルタ１１との間およびルーバ保持枠１４ａとフィルタ１１との間の気密性がさらに高められている。ルーバ１４ｂは、フィルタ１１を通して浄化された空気を、角度を変えて風向を調整することにより室内に拡散させることができる。 Next, the operation will be described.
The filter device 10 is used by arranging a louver member 14 on the indoor side so as to blow air into, for example, a clean room production device machine room and the like, and connecting the duct connection frame 12 to the duct opening 1 attached to the ceiling surface. The filter 11 purifies the air blown from the duct port 1 and supplies it to the room as clean air. The back facing surface 12c of the duct connection frame 12 and the front facing surface 14e of the louver holding frame 14a are in close contact with the periphery of the back surface and the front surface of the filter 11, respectively. Leakage is prevented. Further, the gasket 17 further enhances the airtightness between the duct connection frame 12 and the filter 11 and between the louver holding frame 14 a and the filter 11. The louver 14b can diffuse the air purified through the filter 11 into the room by changing the angle and adjusting the air direction.

フィルタ装置１０は、フィルタ１１をダクト接続枠１２とルーバ部材１４との間に挟み、各固定部材１６が各ダクト側取付孔１２ｄと各ルーバ側取付孔１４ｆとに着脱可能に取り付けられてフィルタ１１を着脱可能に固定している。このため、フィルタ１１の固定にケーシングを必要としないので、ケーシングにかかる材料費の低減およびその取付け作業時間の短縮を図ることができる。各固定部材１６を緩め、フィルタ１１の上方、各側方、または下方のうちのいずれかの固定部材１６を２本取り外せば、ダクト接続枠１２とルーバ部材１４との間からフィルタ１１を取り外して容易に交換することができ、メンテナンスが容易である。ダクト側支持部材１３とルーバ側支持部材１５とが、ダクト側支持部材取付孔１３ｃおよびルーバ側支持部材取付孔に固定部材１６を貫通されて両側からフィルタ１１を支持した状態でフィルタ１１に固定されるため、フィルタ１１を確実に支持し固定することができる。また、従来は、重いケーシングを取り付けていたため、施工性が悪かったが、フィルタ装置１０ではケーシングを使用しないため、施工性が良好である。   In the filter device 10, the filter 11 is sandwiched between the duct connection frame 12 and the louver member 14, and each fixing member 16 is detachably attached to each duct side attachment hole 12 d and each louver side attachment hole 14 f. Is fixed detachably. For this reason, since a casing is not required for fixation of the filter 11, the material cost concerning a casing and the shortening of the installation operation time can be aimed at. By loosening each fixing member 16 and removing two fixing members 16 above, each side, or below the filter 11, the filter 11 is removed from between the duct connection frame 12 and the louver member 14. It can be easily replaced and maintenance is easy. The duct-side support member 13 and the louver-side support member 15 are fixed to the filter 11 with the duct-side support member mounting hole 13c and the louver-side support member mounting hole penetrating the fixing member 16 and supporting the filter 11 from both sides. Therefore, the filter 11 can be reliably supported and fixed. Moreover, conventionally, since the heavy casing was attached, workability was bad, but in the filter apparatus 10, since the casing is not used, the workability is good.

図２および図３に示すように、フィルタ装置１０は、フィルタ１１の両側方の固定部材１６が１箇所ずつであってもよい。この場合、各固定部材１６を緩め、一方の側方の固定部材１６を１つだけを取り外すことにより、フィルタ１１を取り外すことができ、交換などのメンテナンスがさらに容易である。   As shown in FIGS. 2 and 3, the filter device 10 may have one fixing member 16 on each side of the filter 11. In this case, the filter 11 can be removed by loosening each fixing member 16 and removing only one fixing member 16 on one side, and maintenance such as replacement is further facilitated.

なお、フィルタ装置１０は、図３（ａ）に示すように、フィルタ１１の正面を横方向に向けた状態、あるいは、図３（ｂ）に示すように、フィルタ１１の正面を下方に向けた状態で取り付けることができる。このため、フィルタ装置１０を設置するクリーンルームの形状や大きさ、天井や壁の設置位置、ダクトの設置条件などに合わせて、フィルタ１１の向きを変えて取り付けることができる。   3A, the filter device 10 is in a state where the front surface of the filter 11 is directed in the lateral direction, or as illustrated in FIG. 3B, the front surface of the filter 11 is directed downward. Can be installed in a state. Therefore, the direction of the filter 11 can be changed according to the shape and size of the clean room in which the filter device 10 is installed, the installation position of the ceiling or wall, the installation conditions of the duct, and the like.
