Description

【０００１】
【発明の属する技術分野】
本発明は、屋外に設置した配電盤、制御盤等の盤類のキャビネット内に換気口から雨水が浸入するのを防止させて換気を行う盤用換気装置に関するものである。
【０００２】
【従来の技術】
キャビネット内に雨水が浸入するのを防止させて換気を行う盤用換気装置としては、換気口の外側にガラリを設け、これにより先ず雨水の浸入を防止して、ガラリを通過した雨水はガラリの内側に配設した防塵用フィルタにより防ぐものが普通であった。
【０００３】
【発明が解決しようとする課題】
ところが、この従来のものにあっては、暴風やビル風等により吹き上げられる雨水の噴流は防塵用フィルタを通過して浸入し、また、雨水の浸入を防止できるように防塵用フィルタを厚くしたり、フィルタの目を細かくした場合に換気効率が悪くなる問題がある。
【０００４】
【課題を解決するための手段】
前記の課題を解決するためになされた本発明の盤用換気装置は、外側ガラリに内側ガラリと防塵フィルタ収納部を仮装着したうえキャビネットに開口した換気孔に外側から取り付ける盤用換気装置であって、前記防塵フィルタ収納部にフィルタ脱落防止カバーを取り付けて、該フィルタ脱落防止カバーは換気扇を取り付け可能として、さらに、前記フィルタ脱落防止カバーは係止鉤片を前記防塵フィルタ収納部に係合させるとともに止めねじにより着脱自在として取り付けることを特徴とするものを請求項１に係る発明とする。この請求項１の発明において、内側ガラリと防塵フィルタ収納部の取付フランジを外側ガラリの周枠部の内側に嵌合して仮装着したものを請求項２に係る発明とする。また、前記請求項１又は２の発明において、外側ガラリと内側ガラリの間に空間を設けたものを請求項３に係る発明とする。また、これらの発明において、内側ガラリに設けたガラリ板の先端を下向きとしたものを請求項４に係る発明とし、また、請求項１〜３の発明において、内側ガラリのガラリ板を上向きにしたものを請求項５に係る発明とする。そして、前記請求項２〜５の何れかの発明において、内側ガラリの垂直板を外側ガラリの開口）に対応するように設けたものを請求項６に係る発明とし、また、これらの発明において、フィルタ脱落防止カバーにガラリ板を設けたものを請求項７に係る発明とし、さらに、これらの発明おいて、フィルタ脱落防止カバーにガラリ板を設けたものを請求項８に係る発明としたものである。
【０００５】
【発明の実施の形態】
次に、本発明の好ましい実施の形態を示す。
１は板状のガラリ本体１１に先端が外向きで斜め下向きの多数のガラリ板１２を配設して各ガラリ板１２により横長の換気口１２ａを形成した外側ガラリであり、該外側ガラリ１のガラリ本体１１の周縁には内向きの周枠部１３が張設されている。２は板状のガラリ本体２１に多数の傾斜板よりなるガラリ板２２を配設して各ガラリ板２２により横長の換気口２２ａを形成した内側ガラリであり、該内側ガラリ２は前記外側ガラリ１に仮装着可能とされている。即ち、図６に示す実施形態においては、板状のガラリ本体２１の周縁を前記外側ガラリ１の周枠部１３の内面に防水用のパッキン１４を介して嵌合して仮装着し、また、図７に示す実施形態においてはパッキン１４を介することなく周枠部１３に直接嵌合して仮装着をするものとしている。さらに、図８に示す実施形態にあっては、外側ガラリ１の背面４隅に取付ボルト１５を植設して、該取付ボルト１５に内側ガラリ２の四隅に穿設したボルト挿通孔２３を嵌合して仮装着させている。
【０００６】
３は前記内側ガラリ２の背面に設けた防塵フィルタ収納部、この防塵フィルタ収納部３は枠筒体３１の前縁に外形寸法を内側ガラリ２の外形寸法と略同一とした取付フランジ部３２を張設したもので、該取付フランジ部３２を内側ガラリ２の背面に添装して設けられており、前記内側ガラリ２と同様に外側ガラリ１に仮装着可能とされている。なお、防塵フィルタ収納部３を内側ガラリ２と一体構造とした場合には内側ガラリ２を外側ガラリ１に仮装着することにより防塵フィルタ収納部３も仮装着されることは勿論である。
【０００７】
４は防塵フィルタ収納部３の背面開口３３に取り付けるフィルタ脱落防止カバーであり、該フィルタ脱落防止カバー４は下端に形成した係止鉤片４１を防塵フィルタ収納部３の下部に折曲形成した折曲板部３４に係合させるとともに上端側を止めねじ４２により着脱自在として取り付けられている。また、このフィルタ脱落防止カバー４には換気扇５が取付可能とされている。即ち、図示の実施形態ではフィルタ脱落防止カバー４の四隅に設けた押え片４３にねじ孔４４を設けて止めねじ４５により換気扇５を取付可能としている。なお、フィルタ脱落防止カバー４に係止孔を設け、換気扇側に係止爪を設けてもよく、取付手段は特に限定されるものではない。さらに、図１３に示すように該フィルタ脱落防止カバー４にガラリ４６を設けてもよい。６は外側ガラリ１と内側ガラリ２との間に形成した空間であり、該空間６は外側ガラリ１の四隅に取り付けた取付ナット１６をスペーサとして形成されている。
【０００８】
また、前記内側ガラリ２の板状のガラリ本体２１に多数配設したガラリ板２２の形状は、図１〜図８に示す実施形態においてはガラリ板２２をガラリ本体２１から後向き斜め下向きとし、図９に示す実施形態においてはガラリ板２２を前向き斜め上向きとし、図１０に示す実施形態においてはガラリ板２２をガラリ本体２１から後向き斜め下向きとしたうえ先端下方を垂直となるように折り曲げたものとしている。また、図１１に示す実施形態においては内側ガラリ２のガラリ板２２を外側ガラリ１のガラリ板１２と同数として、対応するガラリ板２２を外側ガラリ１のガラリ板１２より少し下方に位置させて言い換えれば互い違いに配置し、ガラリ板１２からの雨水の大部分が垂直部２２ｃに当たるようにしておきガラリ本体２１から後向き斜め下向きとし、図１２に示す実施形態においては内側ガラリ２のガラリ２２を外側ガラリ１のガラリ板１２と同数として、対応するガラリ板２２を外側ガラリ１のガラリ板１２より少し下方に位置させて言い換えれば互い違いに配置し、ガラリ板１２からの雨水の大部分が垂直部２２ｃに当たるようにしておきガラリ本体２１から後向き斜め上向きに形成している。また、図１３に示す実施形態においては、図１の実施形態のものにフィルタ脱落防止カバー４にガラリ板４６を設けたものである。
【０００９】
このように構成されたものは、外側ガラリ１に内側ガラリ２と防塵フィルタ収納部３を仮装着して組み合わせた状態でキャビネット７に開口した換気孔８に外側から取り付けるものであるから、取り付けが作業を容易となるものである。この場合、内側ガラリ２と防塵フィルタ収納部３の取付フランジ部３２を外側ガラリ１の周枠部１３の内側に嵌合して仮装着することにより、外側ガラリ１の四隅に取り付けた取付ナット１６と内側ガラリ２の四隅に穿設したボルト挿通孔２３及び防塵フィルタ収納部３の取付フランジ部３２の四隅に穿設したボルト挿通孔３３とが位置ずれしないのでキャビネット７側から螺合する取付ボルト１７の螺合作業も容易となり、防塵フィルタ収納部３と内側ガラリ２を一体構造とした場合にはさらに作業が容易となる。
【００１０】
そして、本発明にか係る盤用換気装置は前記したとおり、外側ガラリ１に内側ガラリ２と防塵フィルタ収納部３を組み合わせたものであるから、外側ガラリ１を通過した雨水は内側ガラリ２に当ったうえ下方に流下して外部に排出され、また、霧化した雨水は防塵フィルタ収納部３に収納した防虫網９ａ、防塵フィルタ９ｂ等のフィルタ類９により阻止されるのでキャビネット７内に雨水が浸入する虞が無いものである。
【００１１】
また、前記防塵フィルタ収納部３にはフィルタ脱落防止カバー４が取り付けられているので、防塵フィルタ収納部３に収納したフィルタ類９が内側ガラリ２を通して吹き込む風で脱落する虞のないものである。さらに、この防塵フィルタ収納部３は換気扇取り付け可能なものとされているので、換気効率を高めるため換気扇５を後付けする場合に追加部品を用意することなく取り付けできるものであり、また、換気扇５はフィルタ脱落防止カバー４に取り付けられていることから、フィルタ脱落防止カバー４を外すことにより換気扇５も防塵フィルタ収納部３の背面開口から外れるのでフィルタ類９の交換作業の障害とはならないものである。
【００１２】
次に、外側ガラリ１と内側ガラリ２との間に空間６を設けることにより、内側ガラリ２は外側ガラリ１から離れるためその分雨水の到達距離が遠くなり、内側ガラリ２を通過する雨水をより減少させることができる。また、外側ガラリ１の開口１９と内側ガラリ２の開口２９とを合致させなくともよいので、外側ガラリ１と内側ガラリ２のガラリ板の枚数選定や、外側ガラリ１の開口１９に対応する内側ガラリ２の垂直板２２ｃを配置して雨風の大部分を垂直板２２ｃに当たるようにして通過する雨水を減少させることができる。
【００１３】
また、内側ガラリ２の板状のガラリ本体２１に多数配設したガラリ板２２の形状を、図１〜図８に示す実施形態のようにガラリ板２２をガラリ本体２１から後向き斜め下向きとしたものにあっては、ガラリ２２板が防塵フィルタ収納部３内に入り込む構成となるからガラリ板２２から流れ落ちた雨水は防塵フィルタ収納部３の底部からガラリ本体２１の下方に設けた水抜き孔２４を介して外側ガラリ１の周枠部１３の下枠板１３ａに設けた水抜き部である切欠部１３ｂから外部に排出されることとなる。
【００１４】
図９に示す実施形態に示すように、ガラリ板２２を前向き斜め上向きとしたものにあっては、ガラリ板２２が空間６に位置することとなるから、雨水が防塵フィルタ収納部３に入る前に空間６の下方即ち、外側ガラリ１の周枠部１３の下枠板１３ａに流れ落ちるから防水性能を上げることができる。また、この実施形態ではガラリ板２２が防塵フィルタ収納部３内に位置しないのでその分防塵フィルタ収納部３の厚さを薄くすることができ装置全体の厚さを薄くすることができる。
【００１５】
図１０に示す実施形態のように、ガラリ板２２をガラリ本体２１から後向き斜め下向きとしたうえ先端下方を垂直となるように折り曲げたものにあっては、この垂直個所により雨水が真下に流下するのでキャビネット内への浸入をより防止できるものである。
【００１６】
また、図１１に示す実施形態のように、内側ガラリ２のガラリ板２２を外側ガラリ１のガラリ板１２と同数として、対応するガラリ板２２を外側ガラリ１のガラリ板１２より少し下方に位置させてガラリ本体２１から後向き斜め下向きとしたものにあっては、外側ガラリ１を通過して浸入する雨水を内側ガラリ２の開口の無い垂直板２２ｃに当て、勢いを減少させ、防塵フィルタ収納部３への浸入を抑制することができる。
【００１７】
さらに、図１２に示す実施形態のように内側ガラリ２のガラリ板２２を外側ガラリ１のガラリ１２板と同数として、対応するガラリ板２２を外側ガラリ１のガラリ１２より少し下方に位置させてガラリ本体２１から後向き斜め上向きに形成したものにあっては、外側ガラリ１から浸入する雨水を内側ガラリ２の開口の無い垂直板２２ｃに当て、勢いを減少させ、防塵フィルタ収納部３への浸入を抑制するとともに雨水の流れる向きを真上に変え、防塵フィルタ収納部３への浸入をさらに抑制するものである。
【００１８】
また、図１３に示すようにフィルタ脱落防止カバー４にガラリ板４６を設けていることにより内側ガラリ２で防ぎ切れない雨水があっても、該ガラリ板４６によりキャビネット内への浸入を阻止できるものである。
【００１９】
【発明の効果】
以上に説明したように、本発明の盤用換気装置は外側ガラリに内側ガラリと防塵フィルタ収納部を仮装着してキャビネットに開口した換気孔に外側から取り付けるものであるから、取り付け作業を容易に行えるものであり、また、外側ガラリを通過して浸入した雨水は内側ガラリにより阻止されるのでキャビネット内への浸入を防止できるものである。
よって、本発明は従来の盤用換気装置の問題点を解決したものとして、業界にもたらす益大なものである。

Reference numeral 6 denotes a space formed between the outer louver 1 and the inner louver 2, and the space 6 is formed with mounting nuts 16 attached to the four corners of the outer louver 1 as spacers.
[0008]
Further, the shape of the louver plate 22 disposed in the plate-like louver main body 21 of the inner louver 2 is such that the louver plate 22 is inclined rearward and downward from the louver main body 21 in the embodiment shown in FIGS. In the embodiment shown in Fig. 9, the louver plate 22 is inclined forward and upward, and in the embodiment shown in Fig. 10, the louver plate 22 is inclined backward and downward from the main body 21 and the lower end of the louver is bent vertically. Yes. In the embodiment shown in FIG. 11, the number of the louver plates 22 of the inner louver 2 is the same as that of the louver plates 12 of the outer louver 1, and the corresponding louver plates 22 are positioned slightly below the louver plate 12 of the outer louver 1. For example, in the embodiment shown in FIG. 12, the louver 22 of the inner louver 2 is the outer louver 22 in a staggered manner so that most of the rainwater from the louver 12 hits the vertical part 22c. As the same number of louver plates 12, the corresponding louver plates 22 are positioned slightly below the louver plate 12 of the outer louver 1, in other words, arranged in a staggered manner, and most of the rainwater from the louver plate 12 hits the vertical portion 22c. In this way, it is formed obliquely upward and backward from the louver main body 21. In the embodiment shown in FIG. 13, a louver plate 46 is provided on the filter drop-off prevention cover 4 in the embodiment shown in FIG. 1.
[0009]
Since what was comprised in this way is attached to the ventilation hole 8 opened to the cabinet 7 in the state which attached the inner side louver 2 and the dustproof filter storage part 3 temporarily to the outer side louver 1, and attached, it is attached from the outside. It will make your work easier. In this case, the mounting nuts 16 attached to the four corners of the outer louver 1 by fitting and temporarily mounting the inner louver 2 and the mounting flange 32 of the dustproof filter storage part 3 inside the peripheral frame 13 of the outer louver 1. And the bolt insertion holes 23 drilled at the four corners of the inner louver 2 and the bolt insertion holes 33 drilled at the four corners of the mounting flange portion 32 of the dustproof filter storage portion 3 are not misaligned. The screwing work of 17 is also facilitated, and the work is further facilitated when the dust-proof filter housing portion 3 and the inner louver 2 are integrated.
[0010]
As described above, the panel ventilator according to the present invention is a combination of the outer louver 1 and the inner louver 2 and the dustproof filter housing 3, so that rainwater that has passed through the outer louver 1 hits the inner louver 2. In addition, the rainwater that flows down and is discharged to the outside is blocked by the filters 9 such as the insect screen 9a and the dust filter 9b stored in the dust filter storage section 3, so that the rain water enters the cabinet 7. There is no risk of intrusion.
[0011]
In addition, since the filter drop prevention cover 4 is attached to the dustproof filter storage portion 3, the filters 9 stored in the dustproof filter storage portion 3 are not likely to drop off due to the wind blown through the inner louver 2. Further, since the dustproof filter storage unit 3 can be attached to a ventilation fan, it can be attached without preparing additional parts when retrofitting the ventilation fan 5 in order to increase ventilation efficiency. Since the filter drop-off prevention cover 4 is attached, removing the filter drop-off prevention cover 4 also removes the ventilation fan 5 from the rear opening of the dust-proof filter housing 3, so that it does not hinder the replacement work of the filters 9. .
[0012]
Next, by providing the space 6 between the outer gallery 1 and the inner gallery 2, the inner gallery 2 is separated from the outer gallery 1, so that the reach of rainwater is increased accordingly, and the rainwater that passes through the inner gallery 2 is further reduced. Can be reduced. Further, since the opening 19 of the outer gallery 1 and the opening 29 of the inner gallery 2 do not have to be matched, the number of the louver plates of the outer gallery 1 and the inner gallery 2 can be selected, and the inner gallery corresponding to the opening 19 of the outer gallery 1 can be selected. Two vertical plates 22c can be arranged to reduce the amount of rainwater that passes through so that most of the rain and wind hits the vertical plates 22c.
[0013]
Further, the shape of the louver plate 22 arranged in a large number on the plate-like louver main body 21 of the inner louver 2 is such that the louver plate 22 is inclined rearward and downward from the louver main body 21 as in the embodiment shown in FIGS. In this case, since the louver 22 plate enters into the dustproof filter housing 3, rainwater that has flowed down from the louver plate 22 has a drain hole 24 provided below the garage body 21 from the bottom of the dustproof filter housing 3. Accordingly, the water is discharged to the outside from a notch portion 13b which is a drainage portion provided in the lower frame plate 13a of the peripheral frame portion 13 of the outer louver 1.
[0014]
As shown in the embodiment shown in FIG. 9, when the louver plate 22 is inclined forward and upward, the louver plate 22 is located in the space 6, so that the rainwater enters the dustproof filter storage unit 3. In addition, the waterproof performance can be improved because it flows down to the lower frame plate 13a of the peripheral frame portion 13 of the outer louver 1 below the space 6. Further, in this embodiment, since the louver plate 22 is not located in the dustproof filter housing portion 3, the thickness of the dustproof filter housing portion 3 can be reduced correspondingly, and the thickness of the entire apparatus can be reduced.
[0015]
As in the embodiment shown in FIG. 10, in the case where the louver plate 22 is inclined rearward and downward from the louver main body 21 and is bent so that the lower end of the louver is vertical, rainwater flows down directly by this vertical portion. Therefore, it is possible to further prevent the entry into the cabinet.
[0016]
Further, as in the embodiment shown in FIG. 11, the number of the louver plates 22 of the inner louver 2 is the same as the number of the louver plates 12 of the outer louver 1, and the corresponding louver plates 22 are positioned slightly below the louver plate 12 of the outer louver 1. In the case where the main body 21 is inclined rearward and downward, the rainwater entering through the outer gallery 1 is applied to the vertical plate 22c without the opening of the inner gallery 2 to reduce the momentum, and the dustproof filter housing 3 Can be prevented from entering.
[0017]
Further, as in the embodiment shown in FIG. 12, the number of the louver plates 22 of the inner louver 2 is the same as that of the louver 12 plates of the outer louver 1, and the corresponding louver plates 22 are positioned slightly below the louver 12 of the outer louver 1. In the case where the main body 21 is formed so as to be inclined obliquely upward, the rainwater entering from the outer louver 1 is applied to the vertical plate 22c without the opening of the inner louver 2 to reduce the momentum and to enter the dustproof filter storage part 3. In addition to being suppressed, the direction in which the rainwater flows is changed to a position directly above to further suppress intrusion into the dustproof filter storage unit 3.
[0018]
Further, as shown in FIG. 13, by providing a louver plate 46 on the filter drop prevention cover 4, even if there is rainwater that cannot be prevented by the inner louver 2, the louver plate 46 can prevent entry into the cabinet. It is.
[0019]
