Description

本発明は、太陽光発電システムに用いられ、太陽電池が発電する直流電力を交流電力に変換するパワーコンディショナに関する。   The present invention relates to a power conditioner that is used in a solar power generation system and converts DC power generated by a solar cell into AC power.

従来、太陽光発電システムに用いられ、太陽電池が発電する直流電力を交流電力に変換するパワーコンディショナが用いられている。パワーコンディショナには、例えば特許文献1に示すように、屋外に設置して用いられるものがある。   Conventionally, a power conditioner that is used in a solar power generation system and converts DC power generated by a solar battery into AC power is used. Some power conditioners are installed and used outdoors, as shown in Patent Document 1, for example.

特許第4063716号公報Japanese Patent No. 4063716

上記のように、屋外に設置して用いられるパワーコンディショナは、壁面に固定された取付板に対してパワーコンディショナの本体を引っ掛けて取り付けられる場合がある。雨天時には、壁面を伝って取付板に到達した水が、取付板の側面に集中して流れ落ちる。そのため、取付板の側面の下方部分で壁面に汚れが生じやすく、住宅の外観を損なってしまうという問題があった。   As described above, the power conditioner installed and used outdoors may be attached by hooking the main body of the power conditioner to the mounting plate fixed to the wall surface. When it rains, the water that reaches the mounting plate along the wall concentrates on the side surface of the mounting plate and flows down. Therefore, there is a problem in that the wall surface is easily contaminated at the lower part of the side surface of the mounting plate, and the appearance of the house is impaired.

本発明は、上記に鑑みてなされたものであって、壁面に汚れが生じるのを抑えることができる屋外設置型のパワーコンディショナを得ることを目的とする。   This invention is made | formed in view of the above, Comprising: It aims at obtaining the outdoor installation type power conditioner which can suppress that a stain | pollution | contamination arises on a wall surface.

上述した課題を解決し、目的を達成するために、本発明は、壁面に取り付けられて、太陽電池が発電する直流電力を交流電力に変換する直交変換回路を備えるパワーコンディショナであって、直交変換回路を内部に収容する本体と、本体の背面から本体よりも下方に突出する水切板と、を備え、水切板は、本体の横幅よりも広い横幅に形成され、本体よりも下方に突出する部分が本体側に折り曲げられていることを特徴とする。   In order to solve the above-described problems and achieve the object, the present invention is a power conditioner including an orthogonal transformation circuit that is attached to a wall surface and converts DC power generated by a solar cell into AC power. A main body that houses the conversion circuit and a draining plate that protrudes downward from the main body from the back of the main body. The draining plate is formed to have a width wider than the width of the main body, and protrudes downward from the main body. The portion is bent toward the main body.

本発明によれば、水切板が本体よりも横幅が広いので、本体の側方で壁面を流れ落ちる水は、水切板上を流れることになる。そして、水切板上を流れる水は、水切板の下端に至る。水切板は本体よりも下方に突出する部分が本体側に折り曲げられているので、水切板の下端は壁面から離れることとなる。したがって、水切板上を流れる水は水切板の下端から滴下され、壁面を流れ落ちない。そのため、壁面に汚れが生じるのを抑えることができるという効果を奏する。   According to the present invention, since the draining plate is wider than the main body, the water flowing down the wall surface on the side of the main body flows on the draining plate. And the water which flows on a draining board reaches the lower end of a draining board. Since the portion of the draining plate that projects downward from the main body is bent toward the main body, the lower end of the draining plate is separated from the wall surface. Therefore, the water flowing on the draining plate is dripped from the lower end of the draining plate and does not flow down the wall surface. Therefore, there is an effect that it is possible to suppress the occurrence of contamination on the wall surface.

実施の形態1.
図1は、本発明の実施の形態1にかかるパワーコンディショナの外観斜視図である。図2は、パワーコンディショナが備える直交変換回路を示す図である。パワーコンディショナ100は、本体1と取付板2を備える。本体1の内部には直交変換回路3が収容される。
Embodiment 1 FIG.
FIG. 1 is an external perspective view of a power conditioner according to a first embodiment of the present invention. FIG. 2 is a diagram illustrating an orthogonal transform circuit included in the power conditioner. The power conditioner 100 includes a main body 1 and a mounting plate 2. An orthogonal transformation circuit 3 is accommodated in the main body 1.

直交変換回路3は、昇圧部4、インバータ部5、フィルタ部6を有する。図2に示すように、太陽光発電用のパワーコンディショナ100は、太陽電池50の発電電圧を昇圧部4で昇圧し、インバータ部5で交流に変換し、フィルタ部6で波形を整えて商用系統に出力する。   The orthogonal transform circuit 3 includes a booster unit 4, an inverter unit 5, and a filter unit 6. As shown in FIG. 2, the power conditioner 100 for photovoltaic power generation boosts the power generation voltage of the solar cell 50 by the boosting unit 4, converts it to alternating current by the inverter unit 5, and adjusts the waveform by the filter unit 6 for Output to the grid.

図3は、本体1と取付板2を分解した状態を示す斜視図である。パワーコンディショナ100は、屋外設置型のものであり、建物の壁面に取り付けられて用いられる。パワーコンディショナ100は、壁面に固定された取付板2に本体1を保持させることで壁面に取り付けられる。   FIG. 3 is a perspective view showing a state in which the main body 1 and the mounting plate 2 are disassembled. The power conditioner 100 is an outdoor installation type, and is used by being attached to a wall surface of a building. The power conditioner 100 is attached to the wall surface by holding the main body 1 on the mounting plate 2 fixed to the wall surface.

図4は、壁面7に固定された取付板2の横断面図である。図4に示すように、取付板2は、ビスなどを用いて壁面7に固定される。そして、取付板2に形成された引っ掛け部2aに本体1を引っ掛けることで、本体1が取付板2に保持される。このように、取付板2は、本体1の背面側に設けられることとなる。   FIG. 4 is a cross-sectional view of the mounting plate 2 fixed to the wall surface 7. As shown in FIG. 4, the mounting plate 2 is fixed to the wall surface 7 using screws or the like. And the main body 1 is hold | maintained at the attachment plate 2 by hooking the main body 1 on the hook part 2a formed in the attachment plate 2. FIG. As described above, the mounting plate 2 is provided on the back side of the main body 1.

取付板2には、その下側部分に水切板8が一体に設けられている。水切板8は、本体1の横幅よりも広い横幅で形成されている。また、水切板8は、本体1よりも下方に突出するとともに、その下端が壁面7から離れるように本体1側に折り曲げられている。   The mounting plate 2 is integrally provided with a draining plate 8 at a lower portion thereof. The draining plate 8 is formed with a wider width than the width of the main body 1. The draining plate 8 protrudes downward from the main body 1 and is bent toward the main body 1 so that the lower end thereof is separated from the wall surface 7.

以上説明したように、水切板8が本体1よりも横幅が広いので、本体1の側方で壁面7を流れ落ちる水は、水切板8上を流れることになる。そして、水切板8上を流れる水は、水切板8の下端に至る。水切板8の下端は壁面7から離れているので、水切板8上を流れる水は水切板8の下端から滴下され、壁面7を流れ落ちない。そのため、壁面7に汚れが生じるのを抑えることができる。   As described above, since the draining plate 8 is wider than the main body 1, the water flowing down the wall surface 7 on the side of the main body 1 flows on the draining plate 8. Then, the water flowing on the draining plate 8 reaches the lower end of the draining plate 8. Since the lower end of the draining plate 8 is separated from the wall surface 7, the water flowing on the draining plate 8 is dripped from the lower end of the draining plate 8 and does not flow down the wall surface 7. Therefore, it is possible to prevent the wall surface 7 from being contaminated.

なお、水切板8の折り曲げ箇所を1箇所にした例を挙げて説明しているが、これに限られない。例えば、水切板8の折り曲げ箇所を複数設けて、水切板8が本体1の下方に突出する部分で段階的に折り曲げられるように構成してもよい。   In addition, although the example which made the bending place of the water draining board 8 into one place is given and demonstrated, it is not restricted to this. For example, a plurality of folding portions of the draining plate 8 may be provided so that the draining plate 8 is bent stepwise at a portion protruding downward from the main body 1.

また、水切板8が取付板2に一体に形成された例を挙げて説明しているが、これに限られない。例えば、水切板8と取付板2とが別体で構成され、これらをビスなどで連結する構成としても構わない。   Moreover, although the water draining plate 8 has been described by taking an example in which the draining plate 8 is formed integrally with the mounting plate 2, the present invention is not limited thereto. For example, the draining plate 8 and the mounting plate 2 may be configured separately and connected with screws or the like.

実施の形態2.
図5は、本発明の実施の形態2にかかるパワーコンディショナの外観斜視図である。なお、上記実施の形態と同様の構成にてついては、同様の符号を付して詳細な説明を省略する。
Embodiment 2. FIG.
FIG. 5 is an external perspective view of the power conditioner according to the second embodiment of the present invention. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

実施の形態2にかかるパワーコンディショナ150は、本体1を壁面に固定するための固定部11が本体1に一体に形成されている。固定部11には、ビス孔11aが形成されており、このビス孔11aを介して壁面にビスを用いて本体1が固定される。   In the power conditioner 150 according to the second embodiment, a fixing portion 11 for fixing the main body 1 to a wall surface is formed integrally with the main body 1. A screw hole 11a is formed in the fixing portion 11, and the main body 1 is fixed to the wall surface using a screw through the screw hole 11a.

また、本体1には、水切板18が一体に形成されている。水切板18は、本体1の背面側に本体1の幅よりも広く形成されるとともに、本体1の下方に突出した部分が本体1側に折り曲げられて、その下端が壁面から離れるようになっている。   Further, the body 1 is integrally formed with a draining plate 18. The draining plate 18 is formed wider than the width of the main body 1 on the back side of the main body 1, and a portion protruding downward from the main body 1 is bent toward the main body 1 so that its lower end is separated from the wall surface. Yes.

このように、本体1に水切板18を一体に形成した場合にも、上記実施の形態1と同様に、水切板18上を流れる水は水切板18の下端から滴下されるので、壁面7を流れ落ちない。そのため、壁面7に汚れが生じるのを抑えることができる。また、水切板18および固定部11を本体1に一体に形成することで、部品点数の削減を図ることができる。   As described above, even when the draining plate 18 is formed integrally with the main body 1, the water flowing on the draining plate 18 is dropped from the lower end of the draining plate 18 as in the first embodiment. It does n’t flow down. Therefore, it is possible to prevent the wall surface 7 from being contaminated. Further, by forming the draining plate 18 and the fixing portion 11 integrally with the main body 1, the number of parts can be reduced.

以上のように、本発明にかかるパワーコンディショナは、太陽電池が発電する直流電力を交流電力に変換するパワーコンディショナに有用であり、特に、壁面に取り付けられる屋外設置型のパワーコンディショナに適している。   As described above, the power conditioner according to the present invention is useful for a power conditioner that converts DC power generated by a solar cell into AC power, and is particularly suitable for an outdoor installation type power conditioner that is attached to a wall surface. ing.
