この発明は、工場等におけるフードによる室内の排気方
法および排気フードに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for exhausting indoor air using a hood in a factory or the like, and an exhaust hood.
（従来の技術）
型材等のアルマイト処理を行う際、エツチング槽での製
品引き上げ時に多量のエツチングミストが発生する。こ
のためエツチング槽および天蓋に、第１０図に示すよう
に先端にフランジ２１を設けた断面アサガオ形状の排気
フード２０を取付けて、発生するエツチングミストを吸
入し、工場内の空気浄化を図っている。(Prior Art) When performing alumite treatment on molded materials, etc., a large amount of etching mist is generated when the product is pulled up from the etching bath. For this reason, an exhaust hood 20 with a morning glory-shaped cross section and a flange 21 at the tip is attached to the etching tank and the canopy, as shown in Figure 10, to suck in the etching mist generated and purify the air inside the factory. .
（発明が解決すべき問題点）
しかしながら、従来の排気フードは局所排気用のもので
あるため、特に天蓋位置に取付けた場合には第１０図、
第１１図に示す如く排気フ−ド２０を複数設けても吸込
口周辺部のみしか吸引できず、均一な換気ができない。(Problems to be Solved by the Invention) However, since conventional exhaust hoods are for local exhaustion, especially when installed in a canopy position, as shown in Fig. 10,
Even if a plurality of exhaust hoods 20 are provided as shown in FIG. 11, only the area around the suction port can be suctioned, and uniform ventilation cannot be achieved.
また発生するエツチングミストの全量を吸引できないの
で、残ったミストにより材料が腐蝕しやすくなり、作業
環境も汚染されてしまう。Furthermore, since the entire amount of the etching mist generated cannot be sucked out, the remaining mist tends to corrode the material and contaminate the working environment.
さらに排気フード２０と排気ダクト４に連通ずる排気管
２２とはそれぞれエルボ２３を介して連結しており（第
１０図、第１１図参照）。Furthermore, the exhaust hood 20 and the exhaust pipe 22 communicating with the exhaust duct 4 are connected via elbows 23 (see FIGS. 10 and 11).
また各排気管２２の径が小さいため、エルボ２６、排気
管２２内にカスが付着して目詰まりが起こりやすく、吸
引力が低下してしまうという欠点があった。Furthermore, since the diameter of each exhaust pipe 22 is small, debris tends to adhere to the inside of the elbow 26 and the exhaust pipe 22, causing clogging, resulting in a reduction in suction power.
この発明は、前記従来の問題点を解決するために創案さ
れたもので、その目的は天蓋位置においても均一かつ充
分な排気を行うことができ、排気管内の目詰まりが生じ

よる室内の排気方法および排気フードを提供することに
ある。This invention was devised to solve the above-mentioned conventional problems, and its purpose is to be able to perform uniform and sufficient exhaust even in the canopy position, prevent clogging in the exhaust pipe, and prevent maintenance. The object of the present invention is to provide an indoor exhaust method using a hood that is almost unnecessary, and an exhaust hood.
（問題点を解決するための手段）
この出願の第１発明のフードによる室内の排気方法は、
室内上方を覆うフードの下方の開口面積を全体的または
部分的に可変とし、フード側端部の吸入口よりフード内
の空気を横方向に吸引すると共に、吸入口方向に向けて
フード内に吹込エアーを噴射することを特徴とする。(Means for solving the problem) The indoor exhaust method using the hood of the first invention of this application is as follows:
The opening area at the bottom of the hood that covers the upper part of the room is fully or partially variable, and the air inside the hood is sucked in laterally through the inlet at the end of the hood, and is blown into the hood in the direction of the inlet. It is characterized by jetting air.
またこの出願の第２発明の排気フードは、前記第１発明
を実施するための装置であって、室内上方を覆う開口部
を下方に形成したフードの側端に、排気ダクトと連通ず
る吸入口を設け、フードの開口部に複数の可動ガラリ（
風向板）を配設し、フードの吸入口方向に向けた吹込エ
アノズルを、フード内に設けてなることを特徴とする。Further, an exhaust hood according to a second invention of this application is a device for carrying out the first invention, wherein the hood has an opening that covers the upper part of the room and has an inlet port communicating with the exhaust duct at the side end of the hood. and multiple movable louvers (
The hood is characterized by a wind direction plate) and a blowing air nozzle directed toward the inlet of the hood.
以上の排気フードの構成において、ガラリの配置間隔は
吸込口側を密とする。さらに吹込エアノズルは、吸入口
より離れた部分に多く設置する。In the configuration of the exhaust hood described above, the intervals between the louvers are closer on the suction port side. Furthermore, many blowing air nozzles are installed in areas away from the inlet.
（作 用）
室内上面はフードに覆われており、フード下方の開口部
より吸引された排気は、フード内側端の吸入口を通って
排気ダクトへ送られるが、フードの開口面積が広いため
、吸入口に近い位置と離れた位置とでは、開口部の吸引
力に差が生じる。(Function) The upper surface of the room is covered by a hood, and the exhaust gas sucked in from the opening at the bottom of the hood is sent to the exhaust duct through the inlet at the inner end of the hood, but because the opening area of the hood is wide, There is a difference in the suction force of the opening between a position close to the suction port and a position away from the suction port.
そこで本発明では開口部の面積を可変とし、吸入口近傍
の開口面積を小さくし、吸入口より離れるに従い開口面
積を大きくとることにより、開口部の吸引力を均一化し
ている。Therefore, in the present invention, the area of the opening is made variable, and the opening area near the suction port is made small, and the opening area increases as the distance from the suction port increases, thereby making the suction force of the opening uniform.
さらに本発明では吸入口方向に向けてフード内に吹込エ
アーを噴射して負圧を発生させると共に、フード内を流

向上および排気効率の向上を図っている。Furthermore, in the present invention, blow air is injected into the hood toward the suction port to generate negative pressure, and the exhaust gas flowing inside the hood is rectified to improve suction power and exhaust efficiency at a position away from the suction port. We are working to improve this.
