Description

本発明は、半導体工場、食品工場などの清浄空間を必要とするクリーンルームで使用されるファンフィルタユニットに関する。 The present invention relates to a fan filter unit used in a clean room requiring a clean space such as a semiconductor factory or a food factory.

従来、この種のファンフィルタユニットの取付装置は、ファンフィルタユニット構造体のチャンバ下流側に設けられる除塵フィルタと共に積層構造を成してクリーンルーム内の構造物天面に取付けられたものが知られている(例えば特許文献1参照)。   Conventionally, this type of fan filter unit mounting device is known to have a laminated structure with a dust filter provided on the downstream side of the chamber of the fan filter unit structure to be mounted on the top surface of the structure in the clean room. (For example, refer to Patent Document 1).

ここで、ファンフィルタユニットについて具体的な構成を図8を参照しながら説明する。 Here, a specific configuration of the fan filter unit will be described with reference to FIG.

図に示すように、ファンフィルタユニット5はファン1とモータ2からなるファンユニットを内包するチャンバ3とチャンバ3の下方に着脱可能な除塵フィルタ4からなり、前記除塵フィルタ4の断面略C形状または□形状の枠部に設けたフィルタの上流側貫通穴101と下流側貫通穴102を設け、固定手段103により上流側貫通穴101で前記チャンバ3に固定される。また、ファンフィルタユニット5は、開口部を設けた構造物106の開口部天面104に配し、前記チャンバ3に配した本体固定金具11により開口部縁部に固定している。また前記除塵フィルタ4の下流側貫通穴102は、前記チャンバ3に除塵フィルタ4固定後は、穿孔手段105を施している。   As shown in the figure, the fan filter unit 5 includes a chamber 3 containing a fan unit including a fan 1 and a motor 2 and a dust filter 4 that can be attached to and detached from the lower part of the chamber 3. The upstream through hole 101 and the downstream through hole 102 of the filter provided in the square frame are provided, and fixed to the chamber 3 by the upstream through hole 101 by the fixing means 103. The fan filter unit 5 is disposed on the top surface 104 of the opening 106 of the structure 106 provided with the opening, and is fixed to the edge of the opening by the body fixing bracket 11 disposed in the chamber 3. Further, the downstream through hole 102 of the dust filter 4 is provided with a punching means 105 after the dust filter 4 is fixed to the chamber 3.

また、フィルタの交換やモータのメンテナンス交換などの際、ファンフィルタユニットを除塵フィルタと共に構造物から一旦メンテナンスのための作業スペースに移動し、フィルタ、モータなどをファンフィルタユニットから分離する必要がある。除塵フィルタを分離する際、一般的に除塵フィルタは本体下面よりねじ等の固定手段で固定されているので、除塵フィルタが固定された状態でファンフィルタユニットを天地逆にひっくり返し、穿孔手段を取り除き、構成部品の除塵フィルタを取り外す必要があり、着脱に有する時間と手間がかかるものであった。   In addition, when the filter is replaced or the motor is replaced, it is necessary to move the fan filter unit together with the dust filter from the structure to the work space for maintenance, and to separate the filter, motor, and the like from the fan filter unit. When separating the dust filter, the dust filter is generally fixed from the bottom of the main body with fixing means such as screws, so the fan filter unit is turned upside down with the dust filter fixed, and the punching means is removed. Therefore, it is necessary to remove the dust filter of the component, which takes time and labor to attach and detach.

( Reference Example 3 )
As shown in FIG. 7, instead of the holding part 13 described in the reference example 2 , the fixing bolt 8 is inserted into a support hole (not shown) of the main body fixing bracket 11 so that the chamber 3 can be temporarily fixed. I have to.

上記構成において、除塵フィルタ4を交換するときは、チャンバ3を上方に平行移動したときに、先に取り外した固定用ボルト8を本体固定金具11の支持穴(図示せず)に挿入して、チャンバ3を仮固定することにより、不使用部品を有効利用して、部品点数を削減できるとともに、不使用時に紛失することを防ぐことができる。   In the above configuration, when the dust filter 4 is replaced, when the chamber 3 is translated upward, the fixing bolt 8 previously removed is inserted into the support hole (not shown) of the main body fixing bracket 11, By temporarily fixing the chamber 3, it is possible to effectively use unused parts, reduce the number of parts, and prevent them from being lost when not in use.

立壁面をなす構造物にファンフィルタユニットを取付けた場合に、除塵フィルタの交換に際して、チャンバのみをスライドして仮固定することにより、設置方向の異なるフィルタの交換作業の用途に適用できる。   When the fan filter unit is attached to a structure having a standing wall surface, when replacing the dust removal filter, only the chamber is slid and temporarily fixed, so that it can be applied to the replacement work of filters having different installation directions.
