Description

【０００１】
【発明の属する技術分野】
本発明は分電盤、制御盤等の電気機器収納用箱の換気孔に関するものである。
【０００２】
【従来の技術】
従来、図3及び4に示すように、分電盤、制御盤等の電気機器収納用箱１０に、内部機器の発熱により内部温度上昇を防ぐため、箱体の壁面に換気孔１１を透設し、この換気孔１１に換気扇を組み付けるために換気孔周辺に換気扇取付孔１２を透設していた。しかしながら、換気扇を取付ける際に危険防止のため不用意に手が入らないように換気扇ガードを取付けなければならず、さらに、発熱量の少ない内部機器に変更する時など、換気扇を取り付けない場合には、不用意に手が入らないように図５に示すように換気孔１１を覆い隠すためにブラインド板１３を取り付けていたが、見苦しいものであった。
【０００３】
【発明が解決しようとする課題】
本発明は、上記の問題点を解決するためになされたものであり、電気機器収納用箱の換気孔の美観を優れたものとするとともに、換気扇を取付ける場合には、換気扇ガードを不要とし、換気扇を取り付けない場合にはブラインド板の取付を不要とする電気機器収納用箱の換気孔構造を提供する。
【０００４】
【課題を解決するための手段】
上記の問題を解決した本発明の電気機器収納用箱体の換気孔は、換気扇を装着可能な電気機器収納用箱の換気孔において、複数のスリットを設けるとともに、換気扇取付孔を前記スリットの最も外側の各スリットの外側端部に一連に設け、換気扇取付孔に換気扇を電気機器収納用箱体の内部にねじ止めにより取付けたことを特徴とするものである。
【０００５】
【発明の実施の形態】
次に、図1及び２を参照して本発明の実施形態について説明する。
１は分電盤、制御盤等の電気機器収納用箱体、２は箱体１の側壁に設けられた換気孔であり、この換気孔２は複数のスリット３からなる。この換気孔２を構成する複数のスリット３のうち、最も外側の各スリット３の外側端部には、スリット３と一連の換気扇取付孔４が透設されている。そして必要に応じてねじ止めなどにより電気機器収納用箱体１の内部に換気扇５を取付けるものである。なお、スリット3の本数、間隔は換気風量、換気孔面積等を考慮して決めればよいものであり、換気孔の位置も電気機器収納用箱体の扉などに設けてもよく、この実施形態に限定されるものではない。
【０００６】
まず、電気機器収納用箱体の内部機器の発熱により換気扇を取付ける場合には、換気孔２を構成する複数のスリット３のうち、最も外側の各スリット３の外側端部に透設されている、スリット３と一連の換気扇取付孔４に、鎖線で示す換気扇５をねじ止めなどにより取付ける。そして複数のスリット３を通過して空気の流出が行われ、電気機器収納用箱体内部の温度上昇を抑える。また、換気扇５は電気機器収納用箱体１の内部に取付けられており、スリット３により内部に手などが入らないので換気扇ガードを設ける必要がない。
そして、発熱量の少ない内部機器を使用し、自然放熱を利用し換気扇５が不要な場合に、換気孔２は複数のスリット３で構成されているため不用意に手を入る恐れはないので、そのままの状態で使用すればよく、別途ブラインド板を取付ける必要がない。このとき、換気扇を取付けるための換気扇取付孔４はスリット３と一連に設けられており、一見しては目立たないので、美感に優れているものである。
【０００７】
【発明の効果】
本発明の電気機器収納用箱の換気孔は以上に説明したように構成されているので、換気扇を取付けて使用するときには、換気孔は複数のスリットで構成されているため不用意に手を入る恐れはないので、換気扇ガードを取付ける必要がなく、換気扇が不要な場合にも、換気孔は複数のスリットで構成されているため不用意に手を入る恐れはないので、そのままの状態で使用すればよく、別途ブラインド板を取付ける必要がない。このとき、換気扇を取付けるための換気扇取付孔はスリットと一連に設けられており、一見しては目立たないので、美感に優れているという効果がある。よって本発明は従来の問題点を解消した電気機器収納用箱の換気孔として、その工業的価値は極めて大なるものがある。

BACKGROUND OF THE INVENTION
The present invention relates to a ventilation hole of an electric equipment storage box such as a distribution board or a control board.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 3 and 4, a ventilation hole 11 is provided in the wall surface of the box body in order to prevent the internal temperature from rising due to heat generated by the internal equipment in the electrical equipment storage box 10 such as a distribution board and a control board. In order to assemble the ventilation fan into the ventilation hole 11, the ventilation fan mounting hole 12 is made transparent around the ventilation hole. However, when installing a ventilation fan, it is necessary to attach a ventilation fan guard to prevent inadvertent access to prevent danger, and when a ventilation fan is not installed, such as when changing to an internal device with low heat generation. As shown in FIG. 5, the blind plate 13 was attached to cover the ventilation hole 11 so as not to inadvertently enter the hand, but it was unsightly.
[0003]
[Problems to be solved by the invention]
The present invention has been made to solve the above problems, and has an excellent aesthetic appearance of the ventilation hole of the electrical equipment storage box, and when installing a ventilation fan, makes a ventilation fan guard unnecessary, Provided is a ventilation hole structure for an electric equipment storage box that does not require a blind plate when a ventilation fan is not attached.
[0004]
[Means for Solving the Problems]
The ventilation hole of the electrical equipment storage box of the present invention that has solved the above problems is provided with a plurality of slits in the ventilation hole of the electrical equipment storage box on which the ventilation fan can be mounted, and the ventilation fan mounting hole is located at the most of the slit. It is provided in series at the outer end of each outer slit, and the ventilation fan is attached to the inside of the box for electrical equipment storage by screwing in the ventilation fan mounting hole .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to FIGS.
Reference numeral 1 denotes a box for storing electrical equipment such as a distribution board, a control panel, etc., 2 denotes a ventilation hole provided in a side wall of the box 1, and the ventilation hole 2 includes a plurality of slits 3. Among the plurality of slits 3 constituting the ventilation hole 2, a slit 3 and a series of ventilation fan mounting holes 4 are formed through the outer end of each outermost slit 3. And the ventilation fan 5 is attached inside the box 1 for electrical equipment accommodation by screwing etc. as needed. The number and interval of the slits 3 may be determined in consideration of the ventilation air volume, the ventilation hole area, etc., and the position of the ventilation hole may be provided on the door of the electrical equipment storage box, etc. It is not limited to.
[0006]
First, when a ventilation fan is attached by heat generated from the internal equipment of the electrical equipment storage box, among the plurality of slits 3 constituting the ventilation hole 2, the outermost slits 3 are transparently provided at the outer end portions. The ventilation fan 5 indicated by a chain line is attached to the slit 3 and the series of ventilation fan attachment holes 4 by screwing or the like. And the outflow of air is performed through the some slit 3, and the temperature rise in the box for electrical equipment accommodation is suppressed. Further, the ventilation fan 5 is attached to the inside of the electric equipment storage box 1 and a hand or the like does not enter the slit 3, so that it is not necessary to provide a ventilation fan guard.
And when using an internal device with a small calorific value and utilizing natural heat dissipation and the ventilation fan 5 is unnecessary, the ventilation hole 2 is composed of a plurality of slits 3, so there is no risk of inadvertently putting in hands. It can be used as it is, and there is no need to install a separate blind plate. At this time, the ventilating fan mounting hole 4 for mounting the ventilating fan is provided in series with the slit 3 and is not conspicuous at first glance.
[0007]
【The invention's effect】
Since the ventilation hole of the electrical equipment storage box of the present invention is configured as described above, when the ventilation fan is attached and used, the ventilation hole is composed of a plurality of slits, so care is taken. Since there is no fear, there is no need to install a ventilation fan guard, and even if a ventilation fan is not required, the ventilation hole is made up of multiple slits, so there is no risk of accidental access. There is no need to install a blind plate separately. At this time, the ventilating fan mounting hole for mounting the ventilating fan is provided in series with the slit, and is not conspicuous at first glance, so that there is an effect that the aesthetic sense is excellent. Therefore, the present invention has an extremely large industrial value as a ventilation hole of an electric equipment storage box that has solved the conventional problems.
