【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、例えば半導体産業やバイオ産業において必要とされるクリーンルー ムに使用される空気清浄用のフィルタユニットに関する。 The present invention relates to a filter unit for air cleaning used in a clean room required in, for example, the semiconductor industry or the biotechnology industry.

【0002】[0002]

【従来の技術】[Prior art]

上記クリーンルーム内に清浄な空気を供給するため、送風機の下流側にチャン バ室を介してエアフィルタが取り付けられたフィルタユニットが用いられている 。このような従来のフィルタユニットの構造を図2を用いて説明すると、クリー ンルーム(図示せず)に固定される筐体a内に空気の流れ方向に沿って距離Hを 存して対峙するように2枚の仕切板b・cを筐体aの内周面に溶接し、該2枚の 仕切板b・cに挟まれた空間をチャンバ室dとする。そして、上流側の仕切板b の中央部分にチャンバ室dに連通する送風機取付口eを設け、該送風機取付口e に送風機fの吹出口を連結する。一方、下流側の仕切板cの中央部分に開口部g を開設し、該開口部gをチャンバ室dの外側から覆うようにエアフィルタhを取 り付け、パンチングプレートiからなる吹出口から清浄な空気をクリーンルーム へと供給するようにしている。 In order to supply clean air into the clean room, a filter unit in which an air filter is attached downstream of the blower via a chamber is used. The structure of such a conventional filter unit will be described with reference to FIG. 2, in which a housing a fixed to a clean room (not shown) is faced with a distance H along the air flow direction. The two partition plates b and c are welded to the inner peripheral surface of the casing a, and the space sandwiched between the two partition plates b and c is defined as a chamber chamber d. Then, a blower mounting port e communicating with the chamber d is provided in the central portion of the upstream partition b, and the blower outlet of the blower f is connected to the blower mounting port e. On the other hand, an opening g is opened in the central portion of the partition plate c on the downstream side, an air filter h is attached so as to cover the opening g from the outside of the chamber d, and the air is cleaned from the air outlet formed by the punching plate i. The clean air is supplied to the clean room.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記従来のフィルタユニットでは、チャンバ室d内の気密を確保するために2 枚の仕切板b・cの溶接部分をチャンバ室dの内側から全周にわたってシリコン シール剤等を塗布しなければならない。ところが、この作業はエアフィルタhを 取り付ける前に開口部gから手を挿入して行なわなければならず、作業性が悪い ため作業に長時間と熟練とを要するという不具合がある。また、シール剤の塗布 部分を確認しづらいため、特に2枚の仕切板b・cの間隔Hが短い場合にはシー ル剤を完全に塗布できずチャンバ室dの気密を確保できないおそれがある。 そこで本考案は、上記の問題点に鑑み、簡単に、かつ確実にチャンバ室の気密 を確保することのできるフィルタユニットを提供することを目的とする。 In the above-mentioned conventional filter unit, in order to ensure airtightness in the chamber chamber d, the welded portions of the two partition plates b and c must be coated with a silicone sealant or the like from the inside of the chamber chamber d to the entire circumference. However, this work has to be performed by inserting a hand through the opening g before attaching the air filter h, and the workability is poor, which requires a long time and skill. Further, since it is difficult to confirm the applied portion of the sealing agent, there is a possibility that the sealing agent cannot be applied completely and the airtightness of the chamber chamber d cannot be secured, especially when the distance H between the two partition plates b and c is short. . In view of the above problems, it is an object of the present invention to provide a filter unit that can easily and reliably ensure the airtightness of a chamber.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するために、請求項1の考案は、送風機から空気が圧送される チャンバ室に臨ませてエアフィルタを密設させたフィルタユニットにおいて、プ レス加工等により成形された継ぎ目のない有底筒状部材の内部空間をチャンバ室 にすると共に、有底円筒部材の開口部にシール部材を介してエアフィルタを取り 付け、かつ有底筒状部材の壁部にチャンバ室に連通する送風機取付口を設けたこ とを特徴とする。 また、請求項2の考案は、請求項1の考案において、上記有底筒状部材を、エ アフィルタ及び送風機を取り付けた状態で筐体内に着脱自在に設けたことを特徴 とする。 In order to achieve the above-mentioned object, the invention of claim 1 is a filter unit in which an air filter is densely placed so as to face a chamber chamber in which air is pressure-fed by a blower, and there is no joint formed by press working or the like. A blower that makes the inner space of the bottomed cylindrical member a chamber, attaches an air filter to the opening of the bottomed cylindrical member via a seal member, and communicates with the chamber of the wall of the bottomed cylindrical member. It is characterized by having a mounting port. A second aspect of the present invention is characterized in that, in the first aspect of the invention, the bottomed tubular member is detachably provided in the housing with the air filter and the blower attached.

【0005】[0005]

【作用】[Action]

チャンバ室をプレス加工等により成形した有底筒状部材で形成することにより シール剤を塗布しなければならないような溶接部分を無くし、この有底筒状部材 の開口部分にシール部材を介してエアフィルタを取り付けることによりチャンバ 室の気密を確保するようにした。 そして、これらの作業を筐体外で行ない気密が確保された状態で筐体内に取り 付けるようにすることにより、作業性をより向上させるようにした。 By forming the chamber with a bottomed tubular member formed by press work, etc., the welded part where the sealant has to be applied is eliminated, and the air is inserted into the opening of this bottomed tubular member through the seal member. The filter was attached to ensure the airtightness of the chamber. The workability is further improved by performing these operations outside the housing and mounting them inside the housing while ensuring airtightness.

【0006】[0006]

【実施例】【Example】

以下、本考案フィルタユニットの実施例を図面に基づき説明する。 図1を参照して、1はフィルタユニットを格納する筐体であり、図外のクリー ンルームに固定されている。本考案によるフィルタユニットは該筐体1の外で予 め組み立てるもので、プレス加工により一体に成形された継ぎ目のない有底筒状 部材2を仕切板3にビス4によりねじ留めすることにより組み立てる。このねじ 留めに際し、有底筒状部材2の開口部と仕切板3との間にはシール部材5を介在 させて気密を確保するようにした。一方、筐体1の内周面には仕切板3の取付金 具であるブランケット6を予め溶接等により固定しておき、有底筒状部材2を取 り付けた状態の仕切板3を有底筒状部材1の開口部8側から挿入して該ブランケ ット6に対してビス7により取り付けるようにした。 Hereinafter, embodiments of the filter unit of the present invention will be described with reference to the drawings. Referring to FIG. 1, reference numeral 1 is a housing for housing a filter unit, which is fixed to a clean room (not shown). The filter unit according to the present invention is preassembled outside the housing 1, and is assembled by screwing a seamless bottomed cylindrical member 2 integrally formed by press working with a partition plate 3 with a screw 4. .. At the time of this screwing, a seal member 5 is interposed between the opening of the bottomed tubular member 2 and the partition plate 3 to ensure airtightness. On the other hand, on the inner peripheral surface of the housing 1, a blanket 6 which is a mounting tool for the partition plate 3 is fixed in advance by welding or the like, and the partition plate 3 with the bottomed tubular member 2 attached thereto is provided. The bottom tubular member 1 was inserted from the opening 8 side and attached to the blanket 6 with screws 7.

【0007】 ところで、上記有底筒状部材2の底部には該有底筒状部材2の内部空間である チャンバ室10に連通する送風機取付口9を突設し、該送風機取付口9に送風機 11の吹出口を連結させた。また、仕切板3には予めチャンバ室10に対して開 口する位置に開口部13を開設しておき、該開口部13を介してチャンバ室10 に臨むようにエアフィルタ12を交換自在に取り付けるようにした。そして、エ アフィルタ12を取り付けた後、上記開口部8をパンチングプレート14で覆い 該パンチングプレート14の開口を吹出口としてクリーンルーム内へ清浄な空気 を供給するようにした。By the way, the bottom of the bottomed tubular member 2 is provided with a blower attachment port 9 that communicates with a chamber 10 that is an internal space of the bottomed tubular member 2, and the blower attachment port 9 is provided with a blower. 11 outlets were connected. Further, an opening portion 13 is previously formed in the partition plate 3 at a position where it is opened to the chamber chamber 10, and an air filter 12 is replaceably attached so as to face the chamber chamber 10 through the opening portion 13. I did it. Then, after the air filter 12 was attached, the opening 8 was covered with a punching plate 14 so that clean air was supplied into the clean room using the opening of the punching plate 14 as a blowout port.

【0008】 上記構成によれば、チャンバ室10は有底筒状部材2を仕切板3に取り付ける ことにより形成されるが、有底筒状部材2には上述のごとく継ぎ目がないのでシ ール剤等を塗布する必要がなく、また仕切板3に対して取り付ける際にシール部 材5を介在させているので確実に気密を確保することができる。そしてこの仕切 板3への取り付け作業を筐体1の外部で行なうことができるのできわめて容易に 作業を行なうことができ、また、チャンバ室10の気密テストも容易に行なうこ とができる。According to the above configuration, the chamber chamber 10 is formed by attaching the bottomed tubular member 2 to the partition plate 3, but since the bottomed tubular member 2 is seamless as described above, it is a seal. It is not necessary to apply an agent or the like, and since the seal member 5 is interposed when the partition plate 3 is attached, airtightness can be reliably ensured. Since the work of attaching to the partition plate 3 can be performed outside the housing 1, the work can be performed very easily, and the airtightness test of the chamber 10 can be performed easily.

【0009】[0009]

【考案の効果】[Effect of device]

以上の説明から明らかなように、請求項1の考案によれば、簡単な作業で、か つ熟練を有することなくチャンバ室の気密を確実に確保することができる。 また、請求項2の考案によれば、予めフィルタユニットを筐体外で組み立てる ことができるので、更に作業性が向上すると共に、チャンバ室の気密テスト等を 容易に行なえ、チャンバ室の気密に対する信頼性を向上させることができる。 As is clear from the above description, according to the first aspect of the invention, the airtightness of the chamber can be surely ensured by a simple work and without skill. Further, according to the invention of claim 2, since the filter unit can be assembled in advance outside the housing, the workability is further improved, and the airtightness test of the chamber can be easily performed, and the reliability of the airtightness of the chamber is improved. Can be improved.
