【産業上の利用分野】[Industrial applications]

本考案は可搬式クリーンブース内に濾過処理した清浄空気を一方から巻き上げ ることなく送気できて他方から押出状に排気できるようにした可搬式クリーンブ ースにおける曲面多孔板吹出構造に関するものである。 The present invention relates to a curved perforated plate blowing structure in a portable clean boot in which filtered clean air can be fed into one of the portable clean booths without being rolled up from one side and can be discharged in an extruded form from the other side. .

【従来の技術】[Prior Art]

可搬式クリーンブースは食品工業をはじめとするバイオクリーンルームや半導 体工業をはじめとするインダストリアルクリーンルームに広く用いられ、工場内 の必要なエリアだけを選択的に清浄空間とすることができ、工場全体をクリーン にしないで済むので、経済性、省エネルギー性、省力性から優れた利点がある。 The portable clean booth is widely used in bio-clean rooms such as the food industry and industrial clean rooms such as the semiconductor industry, and it is possible to selectively clean only the necessary areas in the factory, and the entire factory can be used. Since it does not need to be cleaned, it has excellent advantages from economical efficiency, energy saving, and labor saving.

【0003】 従来、可搬式クリーンブースの清浄空気の吹出口は平板形の多孔板がブース天 井面に取り付けられて使用されているが、その吹出口からクリーンブース内に吹 出された清浄空気によりクリーンブース内の塵埃を多量に含む空気は対流や渦流 等を生起して巻き上げられたり攪拌されたりして塵埃を拡散して清浄な空間を確 保することが極めて困難であった。通常の場合、送風量150回/時、ブース内 発塵ゼロ(無負荷)の条件下で、0.5μ径の粉塵が約10,000個(クラス 10000)程度の性能であり、清浄度に劣る欠点があった。Conventionally, as a clean air outlet of a portable clean booth, a flat plate-shaped perforated plate is used by being attached to the booth ceiling surface, but the clean air blown into the clean booth from the outlet is used. As a result, the air containing a large amount of dust in the clean booth was convected and swirled, and was swirled up and agitated, and it was extremely difficult to diffuse the dust and maintain a clean space. Under normal conditions, the airflow rate is 150 times / hour, and there is no dust inside the booth (no load), the performance is about 10,000 particles of 0.5μ diameter (class 10000), and the cleanliness is high. There was an inferior drawback.

【作用及び実施例】[Action and Example]

以下、本考案一実施例の構成を図面を参照しながら作用と共に説明する。 クリーンブース1を構成する4本の脚フレーム2には帯電防止ビニールカーテ ン3が取り付けられ、その下端部に鎖の重り4が付着されて該ブース1内の風圧 に適当に対抗して壁面を構成するようになされている。該ブース1の上部に天井 パネル5が張設され、それと前記カーテン3とによりブース空間6が形成されて いる。 該天井パネル5の上には吐出チャンバー7とそれに隣接させたファンケーシン グ8が取り付けられ、該ファンケーシング8にはその側面に開穿された吸込口9 と該吸込口9部に張設されたプレフィルター10、内部に配置されたファン11 とそのファンモーター12が配設され、前記吐出チャンバー7の下面に穿設され た吐出口13にはメインフィルター(高性能フィルター)14が敷設され、前記 ファンモーター12の作動によりファン11が回転駆動するとファンケーシング 8の吸込口9から外部空気が吸い込まれてプレフィルター10を通る過程で粗濾 過されて吐出チャンバー7内に入気し、該吐出チャンバー7を経由してメインフ ィルター14を通過する過程で精濾過されて吐出口13からブース空間6内に清 浄空気が吐出される。 該吐出口13の下側に位置する天井パネル5には曲面多孔板吹出15が取り付 けられ、前記曲面多孔板吹出15の内部には案内羽根16が吐出チャンバー7の 吐出口13に対して等間隔平行に取り付けられると共に、該各案内羽根16によ り形成される空気の流出方向が曲面17に対して略直角になるように配置されて いる。それにより上記吐出口13から吐出された清浄空気は曲面多孔板吹出15 の案内羽根16間に等量の清浄空気が導入され、且つその流出方向が曲面17に 対して略直角になるようになされているから、該清浄空気は曲面多孔板吹出15 の曲面17を一端部としてブース空間6に放射状に等速に流出する。 従って、曲面多孔板吹出15から流出した清浄空気はブース空間6に向かって 整流となって平行移動的即ちトコロテン式に押し出されて排気される。 そして、前記天井パネル5の下面にはブース空間6を照明する蛍光灯18が取 り付けられ、脚フレーム2の所要箇所には上記ファンモーター12用のファンス イッチ19、上記蛍光灯用の照明スイッチ20、その他、コンセント21が付設 され、また、その下部にプラグ付電源コード22が取り付けられている。前記脚 フレーム2の下端にはストッパー付キャスター23が設けられて、ブース1が可 搬式に構成されている。 Hereinafter, a configuration of an embodiment of the present invention will be described together with its operation with reference to the drawings. An antistatic vinyl carton 3 is attached to the four leg frames 2 that make up the clean booth 1, and a chain weight 4 is attached to the lower end of the legframe 2 to properly oppose the wind pressure in the booth 1 and to protect the wall surface. It is designed to be configured. A ceiling panel 5 is stretched over the booth 1, and a curtain space 3 is formed by the ceiling panel 5 and the curtain 3. A discharge chamber 7 and a fan casing 8 adjacent to the discharge chamber 7 are mounted on the ceiling panel 5, and the fan casing 8 is provided with a suction port 9 opened on the side surface thereof and stretched around the suction port 9. A pre-filter 10, a fan 11 and a fan motor 12 arranged inside the pre-filter 10, and a main filter (high-performance filter) 14 is laid on a discharge port 13 formed in the lower surface of the discharge chamber 7. When the fan 11 is driven to rotate by the operation of the fan motor 12, external air is sucked from the suction port 9 of the fan casing 8 and is coarsely filtered in the process of passing through the pre-filter 10 to be introduced into the discharge chamber 7 to be discharged. Clean air is discharged into the booth space 6 from the discharge port 13 after being finely filtered in the process of passing through the chamber 7 and the main filter 14. That. A curved perforated plate outlet 15 is attached to the ceiling panel 5 located below the ejection port 13, and a guide vane 16 is provided inside the curved perforated plate outlet 15 with respect to the ejection port 13 of the ejection chamber 7. The guide blades 16 are mounted in parallel at equal intervals, and are arranged so that the outflow direction of the air formed by each of the guide vanes 16 is substantially perpendicular to the curved surface 17. As a result, the clean air discharged from the discharge port 13 has an equal amount of clean air introduced between the guide blades 16 of the curved porous plate outlet 15 and its outflow direction is substantially perpendicular to the curved surface 17. Therefore, the clean air radially flows out to the booth space 6 at a constant velocity with the curved surface 17 of the curved porous plate outlet 15 as one end. Therefore, the clean air flowing out from the curved porous plate blowout 15 is rectified toward the booth space 6 and is extruded in a parallel movement, that is, a tokoroten type. A fluorescent lamp 18 for illuminating the booth space 6 is attached to the lower surface of the ceiling panel 5, and a fan switch 19 for the fan motor 12 and a lighting switch for the fluorescent lamp are provided at required portions of the leg frame 2. 20, an outlet 21 is additionally provided, and a power cord 22 with a plug is attached to the lower part thereof. A caster 23 with a stopper is provided at the lower end of the leg frame 2 to make the booth 1 portable.

【考案の効果】[Effect of the device]

本考案は以上の説明により明らかなように、曲面多孔板吹出から流出した清浄 空気はブース空間に向かって整流となって放射状に流動して押し出されて排気さ れるものであるから、濾過処理されてブース空間内に導入された清浄空気は乱流 を生ぜず、従って、塵埃や粉塵等を巻き上げることがないので、高度の清浄度が 確保できるものである。 As is clear from the above description, the present invention is that the clean air that has flowed out from the curved perforated plate is rectified toward the booth space, radially flows, is pushed out, and is exhausted, so that it is filtered. The clean air introduced into the booth space does not generate turbulence and therefore does not wind up dust or dust, so that a high degree of cleanliness can be secured.

【0008】 上記実施例で、送風量150回/時、ブース内発塵ゼロ(無負荷)の条件で、 0.5μ径の粉塵が約10個(クラス10)程度の性能が確認された。In the above-mentioned example, performance of about 10 particles (class 10) having a diameter of 0.5 μm was confirmed under the condition that the air flow rate was 150 times / hour and no dust was generated in the booth (no load).
