Description

本発明は、屋外に設置した配電盤、制御盤等の電気機器キャビネット内に換気口から雨水が浸入するのを防止して換気を行う電気機器キャビネット用ルーバーに関するものである。   The present invention relates to a louver for an electrical equipment cabinet that ventilates by preventing rainwater from entering into electrical equipment cabinets such as switchboards and control panels installed outdoors.

従来の防水構造を採用した電気機器キャビネット用ルーバーとしては、特開2000−295721公報(特許文献1)に示すように、外側のガラリの背面に逆向きの内側ガラリを設けて、これらガラリにより雨水を下方に流下させてルーバー下部に設けた水抜き孔から外部に排出して、また、流下せずフィルタに到達する雨水はフィルタで捕捉したうえフィルタ内を流下させたうえ下部のシンクを経て前記水抜き孔から排出させてキャビネット内に雨水が浸入するのを防止するものであった。   As a louver for an electrical equipment cabinet adopting a conventional waterproof structure, as shown in Japanese Patent Laid-Open No. 2000-295721 (Patent Document 1), a reverse inner louver is provided on the back of an outer louver, and rainwater is generated by these louvers. The rainwater that reaches the filter without flowing down is captured by the filter and then flows down through the filter and passes through the sink at the lower part. It was discharged from the drain hole to prevent rainwater from entering the cabinet.

ところが、この従来のものは内側ガラリを外側のガラリの背面に溶接して製作するのを普通とするため、ルーバーの表面に溶接跡が残る。このため外観品質を良くするため塗装を施しており、ステンレスのように地肌が綺麗で耐食性のある材質であっても塗装を行う必要があり、製作コストがその分高くなるという問題があった。   However, since the conventional one is usually manufactured by welding the inner louver to the back surface of the outer louver, a welding mark remains on the surface of the louver. For this reason, the coating is applied to improve the appearance quality, and it is necessary to perform the coating even if the surface is clean and corrosion-resistant, such as stainless steel, resulting in a problem that the manufacturing cost is increased accordingly.

特開2000−295721公報(図1参照)JP 2000-295721 A (see FIG. 1)

本発明は前記のような問題点を解決して、内側ガラリを外側ガラリに溶接することなく設置でき、また、外側ガラリに取付用のボルト・ナットを溶接することなくフィルタ収納ケースに取り付けができ、外側ガラリの表面に溶接跡がなくて塗装を不要とする防水性に優れた電気機器キャビネット用ルーバーを提供することを目的として完成されたものである。   The present invention solves the above-described problems, and can be installed without welding the inner louver to the outer louver, and can be attached to the filter storage case without welding bolts and nuts for attachment to the outer louver. The present invention has been completed for the purpose of providing a louver for an electrical equipment cabinet that has no weld marks on the surface of the outer louver and is excellent in waterproofness that does not require painting.

本発明の電気機器キャビネット用ルーバーは、キャビネットの換気孔に前面から嵌合して取り付けるフィルタケースの前面開口周縁に連設した取付用フランジ部の枠部に内側ガラリを取り付けたうえ、前記内側ガラリの前面を覆う外側ガラリを該外側ガラリの周縁後方に連設した周枠部を前記取付用フランジ部の周縁を囲装したうえ該周枠部の両側板部の先端に内向きに設けた係止爪を取付用フランジ部の側枠部に設けた係止溝部に係止させて取り付けたことを特徴とするものを基本の発明とする。また、内側ガラリを、フィルタケースの側枠部に設けた低段部に該内側ガラリの両側縁部に張設した係止片部を嵌合させて取り付けてもよい。   The louver for an electrical equipment cabinet of the present invention has an inner louver attached to a frame portion of a mounting flange portion that is continuously provided on the periphery of the front opening of a filter case that is fitted and fitted into a ventilation hole of the cabinet from the front. A peripheral frame portion that is formed by continuously connecting an outer louver covering the front surface of the outer louver and surrounding the rim of the mounting flange portion and inwardly provided at the front ends of both side plate portions of the peripheral rim portion. A basic invention is characterized in that the pawl is attached by being engaged with an engaging groove provided in the side frame of the mounting flange. Further, the inner louver may be attached by fitting a locking piece portion stretched on both side edges of the inner louver to a lower step portion provided on the side frame portion of the filter case.

前記のような本発明は、外側ガラリは取付用のボルト・ナットを溶接することなくフィルタケースに取り付けができるので、外側ガラリの表面に溶接跡がないので地肌が綺麗で耐食性のある材質のものにあっては塗装を不要として安価に提供できるものである。そして、本発明に係るものはフィルタケースと外側ガラリの間に内側ガラリが位置しているので、外側ガラリを通過した雨水は先ずこの内側ガラリにより下方に流下されて外側ガラリの周枠部の下板部に設けた排出口から外部に排出して、流下せずフィルタケースに到達する雨水は該フィルタケースに収納したフィルタで捕捉したうえフィルタ内を流下させたうえフィルタケースの下面を経て前記排出口から排出させてキャビネット内に雨水が浸入す
るのを防止するものである。
In the present invention as described above, since the outer louver can be attached to the filter case without welding the bolts and nuts for attachment, there is no welding mark on the surface of the outer louver, so the surface is clean and has a corrosion-resistant material. In this case, it is possible to provide coating at low cost without requiring painting. In the present invention, since the inner louver is located between the filter case and the outer louver, the rain water that has passed through the outer louver is first caused to flow downward by the inner louver and below the peripheral frame portion of the outer louver. Rainwater that reaches the filter case without flowing down through the discharge port provided in the plate part is captured by a filter housed in the filter case, flows down in the filter, passes through the lower surface of the filter case, and then drains. It is discharged from the outlet to prevent rainwater from entering the cabinet.

また、本発明に係るものは、内側ガラリを該内側ガラリの両側縁部に張設した係止片部をフィルタケースの側枠部に設けた低段部に嵌合したうえ、外側ガラリにより覆って取り付けたものであるから、内側ガラリと外側ガラリの取付作業が容易なものである。   Further, according to the present invention, the engaging piece portion in which the inner louver is stretched on both side edges of the inner louver is fitted to the low step portion provided in the side frame portion of the filter case, and is covered with the outer louver. Therefore, it is easy to attach the inner louver and the outer louver.
