Description

本発明は、各種機器を収納するためのキャビネットに設けられた換気用窓に取り付けられるルーバ装置に関するものである。   The present invention relates to a louver device attached to a ventilation window provided in a cabinet for storing various devices.

キャビネットに電気機器や通信機器を収納した場合、機器からはかなりの発熱が考えられる。近年の情報化に伴って、電気機器や通信機器を用いる場面は多く、キャビネットに密集させて収納させることが増えてきている。そこで、キャビネット内部の空気を換気する必要が出てきており、キャビネットの側面には通気孔を設けたり、換気用の窓を設けてファンを取り付けたりしている。   When electrical equipment and communication equipment are stored in a cabinet, considerable heat can be generated from the equipment. Along with computerization in recent years, there are many scenes where electric devices and communication devices are used, and the number of cases where they are stored in a cabinet is increasing. Therefore, it is necessary to ventilate the air inside the cabinet, and a ventilation hole is provided on the side surface of the cabinet or a fan is attached by providing a ventilation window.

このように構成されたキャビネットに設けられた換気用窓に取り付けられるルーバ装置は、ルーバ装置を構成する部品をキャビネットの内側と外側とから挟んで固定する。キャビネットの外側に取り付けられるカバー体は、複数の通気孔と、それぞれの通気孔を被覆するようにガラリが設けられている。ガラリは、通気孔から空気を取り入れながら、塵埃や雨水の侵入を防ぐため、通気孔の前面側を覆い、下側から空気を取り入れる形状であった。また、通気孔から侵入してしまった塵埃や雨水を下側の通気孔から排出する構造であった。   The louver device attached to the ventilation window provided in the cabinet configured in this manner fixes parts constituting the louver device between the inside and the outside of the cabinet. The cover body attached to the outside of the cabinet is provided with a plurality of vent holes and a louver so as to cover each of the vent holes. The gallery has a shape that covers the front side of the vent hole and takes in air from the lower side in order to prevent dust and rainwater from entering while taking in air from the vent hole. In addition, the structure is such that dust and rainwater that has entered through the air vent are discharged from the lower air vent.

特開2006−329522号公報JP 2006-329522 A

ルーバ装置の設置目的は、キャビネット内部の換気にあるため、カバー体に設ける通気孔はできるだけ大きく設定したい。しかし、大きな通気孔では塵埃や雨水が侵入しやすいという欠点があった。ただ、通気孔にそれぞれ設けられたガラリが、風によって吹き上げられた雨水をよけるため、その下にガラリが設けられている通気孔からの雨水の浸入は防がれていた。図4に示すように、最下位置の通気孔には雨水よけになる構造がないため、雨水が浸入しやすくなっていた。   Since the purpose of installing the louver device is to ventilate the inside of the cabinet, it is desirable to set the vent hole provided in the cover body as large as possible. However, there is a drawback that dust and rainwater are likely to enter through a large vent. However, since the louvers provided in the vent holes prevent rainwater blown up by the wind, the intrusion of rainwater from the vent holes in which the louvers are provided is prevented. As shown in FIG. 4, the lowermost vent has no structure to prevent rainwater, so rainwater easily enters.

そこで本発明は、確実に雨水の浸入を防ぐ構造を提供することを目的とし、その構造は、ルーバ装置表面に取り付けられる、複数の通気孔と、通気孔をそれぞれ被覆するガラリとを設けたカバー体の最下位置の通気孔の下側に、最下位置のガラリと相対面するようにリブを設けることを特徴とする。   Accordingly, an object of the present invention is to provide a structure that reliably prevents the ingress of rainwater, and the structure is a cover provided with a plurality of vent holes attached to the surface of the louver device, and a gall that covers each of the vent holes. A rib is provided on the lower side of the vent hole at the lowermost position of the body so as to face the louver at the lowermost position.

本発明に係るルーバ装置は、ルーバ装置表面に取り付けられる、複数の通気孔と、通気孔をそれぞれ被覆するガラリとを設けたカバー体の最下位置の通気孔の下側に、最下位置のガラリと相対面するようにリブを設けるため、降雨時に風が吹いたときに雨水が吹き上げられて最下位置の通気孔から浸入することを防ぐことができる。簡単な構造であるため、製造コストを抑えて製作することができる。   The louver device according to the present invention has a lowermost position on the lower side of the lowermost vent hole of the cover body provided with a plurality of vent holes attached to the surface of the louver device and a louver covering each of the vent holes. Since the rib is provided so as to face the louver, it is possible to prevent rainwater from being blown up and entering from the lowermost vent hole when wind blows during rain. Since it has a simple structure, it can be manufactured at a low manufacturing cost.

本発明に係るルーバ装置の実施例を図1〜図3の添付図面に基いて説明する。   An embodiment of a louver device according to the present invention will be described with reference to the accompanying drawings of FIGS.

電気機器や通信機器等の各種機器を収納するキャビネットは、機器類から排出される熱によって温度上昇しやすい環境にある。しかも、機器の中には、温度上昇に弱い精密機器も含まれるため、キャビネットからの排熱の必要があった。キャビネットには、換気用窓が設けられ、自然換気をしたり、ファン等を取り付けて強制換気をしたりしている。   Cabinets for storing various devices such as electric devices and communication devices are in an environment where the temperature is likely to rise due to heat exhausted from the devices. In addition, some of the equipment includes precision equipment that is vulnerable to temperature rise, so it was necessary to exhaust heat from the cabinet. The cabinet is equipped with ventilation windows for natural ventilation or forcible ventilation with fans.

ルーバ装置1は、このように設けられた換気用窓に取り付けられるものであり、換気する目的で、且つ塵埃や雨水の侵入を防ぐことのできる構造である。   The louver device 1 is attached to the ventilation window provided in this way, and has a structure capable of preventing intrusion of dust and rainwater for the purpose of ventilation.

ルーバ装置1は前面に複数の通気孔2を有するカバー体3で換気用窓を被覆している。キャビネットにベース体4と固定体5とを互いに対向させて取り付ける。固定体5にカバー体3を固定することでルーバ装置1をキャビネットに装着することができる。   The louver device 1 covers a ventilation window with a cover body 3 having a plurality of ventilation holes 2 on the front surface. The base body 4 and the fixed body 5 are attached to the cabinet so as to face each other. The louver device 1 can be mounted on the cabinet by fixing the cover body 3 to the fixed body 5.

カバー体3に設ける通気孔2は、多くの空気を採り入れられるよう、できるだけ面積を大きく設定する。また、誤って取り込んでしまった塵埃や雨水は下の方の通気孔2から排出させる。そして、それぞれの通気孔2はガラリ6によって被覆する。ガラリ6は庇状に、通気孔2の上辺2aから前面に張り出し、そこから下向きに延接され、通気孔2の前面側はスペースを持ちながら被覆している。通気孔2それぞれに設けられるので、上下に連接される。ガラリ6を設けることで塵埃や雨水の侵入を防いでいる。また、降雨時に風が吹いた場合、雨水が吹き上げられ通気孔2に侵入することがあったが、ガラリ6が通気孔2の下辺2bまで覆うと共に、その下の通気孔2に設けられたガラリ6が上の通気孔2も、通気させる分だけ空けて覆っているので、雨水の侵入を抑えている。   The vent hole 2 provided in the cover body 3 is set as large as possible so that a large amount of air can be taken in. In addition, dust and rainwater taken in by mistake are discharged from the lower vent 2. Each vent hole 2 is covered with a louver 6. The louver 6 projects in a bowl shape from the upper side 2a of the vent hole 2 to the front surface and extends downward therefrom, and covers the front surface side of the vent hole 2 with a space. Since it is provided in each of the vent holes 2, it is connected up and down. Intrusion of dust and rainwater is prevented by providing the louver 6. Further, when the wind blows during rain, rainwater is blown up and may enter the ventilation hole 2. Since the upper ventilation hole 6 is also opened and covered by the amount to be ventilated, the entry of rainwater is suppressed.

さらに本発明では、最下位置に設けられている通気孔2bの下に、その通気孔2bを上側から被覆しているガラリ6に相対面するリブ7を形成する。リブ7は、ルーバ装置1の形状に対向させて、図2示のように円形のルーバ装置の場合、カバー体3の下部の弧の部分に対向させて形成することが美観も損なわず望ましい。このリブ7によって最下位置に設けられた通気孔2cからも空気の取り入れや、一旦取り込んでしまった塵埃、雨水の排出は行いながら、直接的な塵埃や雨水の侵入は抑えることができる。   Further, in the present invention, a rib 7 facing the louver 6 covering the vent hole 2b from above is formed below the vent hole 2b provided at the lowest position. In the case of a circular louver device as shown in FIG. 2, the rib 7 is preferably formed so as to face the shape of the louver device 1 so as to face the arc portion of the lower portion of the cover body 3 without losing aesthetics. Direct entry of dust and rainwater can be suppressed while air is taken in from the air holes 2c provided at the lowest position by the ribs 7 and dust and rainwater once taken in are discharged.
