A structure for fixing is generally used.

またルーバに後付けでファンを取付けるために、特許文献1に示されるように、キャビネットとルーバ取付部材との間にファンを取付ける取付部材を挟持させる構造がある。この取付部材の四隅にはファンを取付けるためのビス止め座部が形成されている。   Further, in order to attach a fan to the louver as a retrofit, there is a structure in which an attachment member for attaching the fan is sandwiched between a cabinet and a louver attachment member as disclosed in Patent Document 1. Screw fixing seats for mounting the fan are formed at the four corners of the mounting member.

しかし特許文献1のような構造であると、ルーバ取付部材とビス止め座部との距離が近いことや、ビス止め座部の相互間の間隔が狭いことにより、ルーバ取付部材を手で回転させて締め付けようとしたときに手がビス止め座部に当たってしまい、締付作業性が悪くなるという問題があった。   However, in the structure as in Patent Document 1, the louver mounting member is rotated by hand because the distance between the louver mounting member and the screw fixing seat portion is short or the distance between the screw fixing seat portions is narrow. When trying to tighten, there is a problem that the hand hits the screw stop seat and the tightening workability deteriorates.

以下に本発明の好ましい実施形態を示す。
図1は本発明の実施形態を示す斜視図、図2と図3はその分解図である。これらの図において、1は電気機器収納用キャビネットの壁面であり、一部のみが矩形に切り取られた状態で図示されている。この壁面はキャビネットの側板であっても、扉であっても、背面板であってもよい。
Preferred embodiments of the present invention are shown below.
FIG. 1 is a perspective view showing an embodiment of the present invention, and FIGS. 2 and 3 are exploded views thereof. In these drawings, reference numeral 1 denotes a wall surface of an electric equipment storage cabinet, and only a part of the wall is shown in a rectangular shape. This wall surface may be a side plate of a cabinet, a door, or a back plate.

2はキャビネットに形成された円形の換気口である。図8に示されるように、換気口2にはキャビネットの外側からルーバ3が取付けられる。ルーバ3は合成樹脂製であり、ルーバ本体の背面には換気口2に挿入される筒状部4が一体成形されている。この筒状部4の外周面にはオネジ5が形成されており、図2、図3に示すようにキャビネットの内側からこのオネジ5にナット状のルーバ取付部材6を螺合させ、ルーバ3を固定している。また、換気口2の内周上とオネジ5の外周上には直線状に切り欠いた直線部23をそれぞれ対応して形成しており、直線部23がそれぞれ当接することでルーバ3がキャビネットに対して回転しない構造となっている。   Reference numeral 2 denotes a circular ventilation port formed in the cabinet. As shown in FIG. 8, a louver 3 is attached to the ventilation opening 2 from the outside of the cabinet. The louver 3 is made of synthetic resin, and a cylindrical portion 4 to be inserted into the ventilation port 2 is integrally formed on the back surface of the louver body. A male screw 5 is formed on the outer peripheral surface of the cylindrical portion 4. As shown in FIGS. 2 and 3, a nut-like louver mounting member 6 is screwed onto the male screw 5 from the inside of the cabinet, and the louver 3 is attached. It is fixed. In addition, linear portions 23 that are notched in a straight line are formed on the inner periphery of the ventilation port 2 and the outer periphery of the male screw 5 respectively, and the louver 3 is attached to the cabinet by the linear portions 23 contacting each other. The structure does not rotate.

上記の構造は従来と同様であるが、この実施形態ではキャビネットの壁面1とルーバ取付部材6との間に取付部材7を介在させ、この取付部材7にファン8と風抜防止部材9とを取付けている。   Although the above structure is the same as the conventional structure, in this embodiment, a mounting member 7 is interposed between the wall surface 1 of the cabinet and the louver mounting member 6, and the fan 8 and the draft prevention member 9 are provided on the mounting member 7. It is installed.

図4に示すように取付部材7は長方形の平板であり、その中央に筒状部4を通すことができる孔10を備えている。また一方の対角位置のみに、ファン取付部12が折曲形成されている。このファン取付部12はネジ孔11を備えたネジ止め用座部であり、ネジ止め用座部は取付部材7の平板部21よりもキャビネットの内側位置に略コ字状に形成して平板部21とネジ止め面22の間に空間を形成している。また取付けた状態において、このネジ止め面22はルーバ取付部材6の厚さよりもキャビネットの壁面1からキャビネット内側の位置に形成してあり、ルーバ取付部材6との干渉をなくしている。また取付部材7の平板部21を貫通させることなく、ファン8と風抜防止部材9とを取付けることができる。なお、オネジ5の外周状に形成した直線部23と対応して、孔10の内周上にも直線部23を形成しておけばファン取付部材がキャビネットやルーバ3に対する回転を防止することができる。   As shown in FIG. 4, the attachment member 7 is a rectangular flat plate, and has a hole 10 through which the tubular portion 4 can pass. Further, the fan mounting portion 12 is bent at only one diagonal position. The fan mounting portion 12 is a screwing seat portion having a screw hole 11, and the screwing seat portion is formed in a substantially U-shape at a position inside the cabinet from the flat plate portion 21 of the mounting member 7. A space is formed between 21 and the screwing surface 22. Further, in the mounted state, the screwing surface 22 is formed at a position inside the cabinet from the wall surface 1 of the cabinet with respect to the thickness of the louver mounting member 6, thereby eliminating interference with the louver mounting member 6. Further, the fan 8 and the air vent prevention member 9 can be attached without penetrating the flat plate portion 21 of the attachment member 7. In addition, if the linear part 23 is formed also on the inner periphery of the hole 10 corresponding to the linear part 23 formed in the outer periphery shape of the external thread 5, the fan mounting member can prevent the rotation with respect to the cabinet or the louver 3. it can.

ファン8は従来と同様のものであり、前記したようにファン8の通風路は排気側に向かって拡大されている。このため、吸気口13は図6のように円形であるが、排気口14は図7に示すように、吸気口13よりもサイズが大きい8角形となっている。   The fan 8 is the same as the conventional one, and the air passage of the fan 8 is expanded toward the exhaust side as described above. Therefore, the intake port 13 is circular as shown in FIG. 6, but the exhaust port 14 is an octagon that is larger in size than the intake port 13 as shown in FIG. 7.

風抜防止部材9は図5に示すような浅い箱状体であり、その中央部にファン8の排気口14の開口以上の大きさに通気口15が形成されている。またその周縁部16は取付部材7のファン取付部12の外側に嵌め込むことができるように折り曲げられている。折り曲げ深さはファン取付部12の突出量とほぼ等しくし、取付状態において風抜防止部材9の周縁部16の先端が、換気口2の周囲の全周にわたってキャビネットの壁面1に当接するようにしておく。これにより、風抜防止部材9によってキャビネット内に位置する換気装置全体を覆うことができるので、ファン8からの排気がキャビネット内部に漏れることを完全の防止することができ、しかも風抜防止部材9を簡易な構造とすることができる。   The ventilating prevention member 9 is a shallow box-like body as shown in FIG. 5, and a vent 15 is formed in the center of the vent 15 so as to be larger than the opening of the exhaust port 14 of the fan 8. Further, the peripheral edge portion 16 is bent so as to be fitted to the outside of the fan attachment portion 12 of the attachment member 7. The folding depth is substantially equal to the protruding amount of the fan mounting portion 12 so that the tip of the peripheral edge portion 16 of the air vent prevention member 9 abuts against the wall surface 1 of the cabinet over the entire circumference around the ventilation port 2 in the mounted state. Keep it. Thereby, since the whole ventilation apparatus located in the cabinet can be covered by the draft prevention member 9, it is possible to completely prevent the exhaust from the fan 8 from leaking into the cabinet, and the draft prevention member 9 can be prevented. Can have a simple structure.

風抜防止部材9は、風抜防止部材9とファン8を取付部材7に同時に取付けるための貫通孔17を一方の対角位置に形成し、ファン8を風抜防止部材9に取付けるネジ孔18を他方の対角位置に形成したものである。このため、先ずファン8を風抜防止部材9にネジ19によって固定したうえ、ネジ20によって風抜防止部材9をファン8とともに取付部材7のファン取付部12に固定することができるので、施工性がよい。またファン8は四隅をネジ19,20により固定されるので、がたつくことがない。なお、取付部材7の一方の対角にのみファン取付部12を形成してあるので、ルーバ取付部材6を手で回して締め付ける際にファン取付部12が邪魔になることがない。また、風抜防止部材を取付部材7と同様に長方形に形成して、共に嵌め合せる構造としたので、風抜防止部材の向きを間違えることなく取付けることができ、作業性がよくなる。   The draft prevention member 9 is formed with through holes 17 at one diagonal position for attaching the draft prevention member 9 and the fan 8 to the attachment member 7 at one diagonal position, and screw holes 18 for attaching the fan 8 to the draft prevention member 9. Is formed at the other diagonal position. For this reason, first, the fan 8 can be fixed to the draft prevention member 9 with the screw 19, and the draft prevention member 9 can be fixed together with the fan 8 to the fan attachment portion 12 of the attachment member 7 with the screw 20. Is good. Further, since the fan 8 is fixed at the four corners by the screws 19 and 20, the fan 8 does not rattle. Since the fan mounting portion 12 is formed only on one diagonal of the mounting member 7, the fan mounting portion 12 does not get in the way when the louver mounting member 6 is turned by hand. Further, since the air vent preventing member is formed in a rectangular shape like the mounting member 7 and fitted together, the air vent preventing member can be attached without making a mistake in direction, and workability is improved.

図8は上記のようにして固定された後の排気側の断面図である。図8に示されるように、ファン8の排気口14は吸気口13よりも拡大されているが、ファン8は風抜防止部材9の通気口15の周囲に当接している。また風抜防止部材9の周縁部16の先端はキャビネットの壁面1に当接しているので、ファン8からの排気がキャビネット内部に漏れることがない。なお、吸気側では図9に示すようにファン8は向きを変えて風抜防止部材9に取付けられるが、この場合にもファン8は風抜防止部材9の通気口15の周囲に当接しており、支障はない。   FIG. 8 is a cross-sectional view of the exhaust side after being fixed as described above. As shown in FIG. 8, the exhaust port 14 of the fan 8 is larger than the intake port 13, but the fan 8 is in contact with the periphery of the vent hole 15 of the ventilating prevention member 9. Moreover, since the front-end | tip of the peripheral part 16 of the ventilation prevention member 9 is contact | abutting to the wall surface 1 of a cabinet, the exhaust_gas | exhaustion from the fan 8 does not leak into the cabinet inside. On the intake side, as shown in FIG. 9, the fan 8 changes its orientation and is attached to the air vent member 9. In this case, however, the fan 8 abuts around the vent 15 of the air vent member 9. There is no hindrance.

以上に説明したように、本発明の電気機器収納箱用換気装置は、ルーバ取付部材の締付作業を容易に行うことができ、またルーバが取付られた換気口の内側にファン8を施工性よく取付けることができる利点がある。   As described above, the ventilating apparatus for an electrical equipment storage box according to the present invention can easily perform the tightening operation of the louver mounting member, and the fan 8 can be installed inside the ventilation port to which the louver is mounted. There is an advantage that can be installed well.
