「産業上の利用分野」
本考案は、クリーンルームにおける天井フイル
ターとその取付け構造に係るものである。[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a ceiling filter in a clean room and its mounting structure.
「従来の技術と考案が解決しようとする課題」
従来、垂直全面層流型のクリーンルームでは、
天井前面にフイルターが配列され、天井チヤンバ

直層流にてクリーンルーム内に流出するようにな
つている。"Problems that conventional technology and ideas are trying to solve" Conventionally, in clean rooms with vertical laminar flow,
Filters are arranged in front of the ceiling, and the air from the ceiling chamber is purified by the filters and flows into the clean room in a vertical laminar flow.
この垂直全面層流型クリーンルームにおけるフ
イルターの取り付けには、通常、第４図又は第５
図の手段がとられる。 The installation of filters in this vertical full-surface laminar flow clean room is usually carried out as shown in Figure 4 or 5.
The measures shown in the figure are taken.
第４図の場合は、吊りボルト１…により格子状
の天井フレーム２を水平に支持し、該天井フレー
ムの上にフイルター３の側板３１を気密に載置す
るものである（参考例実開昭61−204623公報）。 In the case of Fig. 4, a lattice-shaped ceiling frame 2 is horizontally supported by hanging bolts 1, and the side plate 31 of the filter 3 is airtightly placed on the ceiling frame. 61-204623).
また、第５図の場合は、フイルター３は側板３

板相互間にシール材４を介在させている。 In addition, in the case of Fig. 5, the filter 3 is connected to the side plate 3.
By protruding support pieces 33 on the outer periphery of the filters 1 and connecting the support pieces to the hanging bolts 1, the filter 3 is directly supported by the hanging bolts 1, and the sealing material 4 is placed between adjacent side plates. is interposed.

つては、天井フレーム２の下面又は側板３１の下

その幅ａの３〜５倍の長さｂの大きな乱流域ｓが
生ずる欠点がある。 However, when using these filter mounting means, the lower surface of the ceiling frame 2 or the lower surface of the side plate 31 becomes a large dead part, and there are
There is a drawback that a large turbulent area s with a length b that is 3 to 5 times the width a is generated.
ところで、この点を改良すべく、上記第４図の

台形に形成することが提案されている（実開昭62
−147833公報）。 By the way, in order to improve this point, it has been proposed to form the longitudinal section of the ceiling frame into a triangular or trapezoidal shape in the one shown in FIG.
−147833).
しかし、このようにしても、フイルターから流
出する清浄空気は垂直層流（通常、フイルターの
側板が垂直方向であり、ろ過部材が垂直方向に折
り込まれることから、風速ベクトルは垂直方向と
なる。）であるため、実際には、その乱流領域は
ほとんど変わらず、そのまま残つてしまう。 However, even with this method, the clean air flowing out of the filter is a vertical laminar flow (normally, the side plates of the filter are vertical, and the filter member is folded in the vertical direction, so the wind speed vector is vertical.) Therefore, in reality, the turbulent region remains almost unchanged.
一方、天井フレームへのフイルターの取り付け
を容易にするため、フイルターを下方から取り付
けるようにしたものがある（実開昭61−89742公
報）。つまり、下縁が内側に屈曲した回動支持板
を天井フレームから垂設し、該回動支持板でフイ
ルターの側板を抱持するようにしたものである。 On the other hand, in order to facilitate the attachment of the filter to the ceiling frame, there is a structure in which the filter is attached from below (Japanese Utility Model Publication No. 89742/1989). That is, a rotary support plate whose lower edge is bent inward is suspended from the ceiling frame, and the side plate of the filter is supported by the rotary support plate.

くなつて、デツド部の幅ａが益々広くなり、乱流
域ｓが一層大きくなる。 However, in this case, although it is convenient for installation, the width of the frame piece of the frame becomes wider in order to make the required rotation to attach and detach the filter to the rotation support plate, and the width a of the detent part becomes wider. It becomes wider and wider, and the turbulent region s becomes even larger.
本考案は、これらのことを考慮して、上記乱流
域ｓを極力小さくし、併せて、フイルターを下方
から簡単に取り付け得るようにしようとするもの
である。 Taking these matters into consideration, the present invention aims to make the turbulent region s as small as possible, and also to allow the filter to be easily attached from below.
