Description
本発明は、車両用空気調和装置に関するものである。 The present invention relates to a vehicle air conditioner.
従来の車両用空気調和装置は、空調装置本体枠と金属製の上面カバーと側面カバーとから外殻を構成しており、内部に圧縮機、熱交換器、室内送風機等を配置している。
その車両用空気調和装置は取付足により車両の屋根に載置されている。
側面カバーが金属製で形成されている場合は、ＪＩＳ規格の電車用ユニットクーラーＥ６６０２に定められている耐電圧試験に合格するために、側面カバー、上面カバーと空調装置本体枠との隙間及び側面カバー、上面カバーと圧縮機などの内部機器との間に、一定の絶縁距離（少なくともＡ寸法）を設ける必要があった。
この場合、内部機器を収納する空調装置本体枠のサイズは前述の絶縁距離に制約され、外殻全体が大きくなるという問題があった。
そこで、側面カバーをＦＲＰ等の合成樹脂製にすることにより、ＪＩＳ規格の耐電圧試験の規程をクリヤーでき、樹脂で製作した側面カバーと空調装置本体枠の間、または、側面カバーと取付足の隙間寸法をＢ寸法とし、絶縁のための隙間寸法を必要としなくなり、側面カバー含めた外径寸法を大幅に小さくすることができる（例えば、特許文献１参照）。
A conventional vehicle air conditioner has an outer shell made up of an air conditioner body frame, a metal top cover, and a side cover, and a compressor, a heat exchanger, an indoor blower, and the like are disposed therein.
The vehicle air conditioner is mounted on the roof of the vehicle by mounting feet.
When the side cover is made of metal, in order to pass the withstand voltage test defined in the JIS standard train unit cooler E6602, the gap between the side cover, the top cover and the air conditioner main body frame and the side surface It was necessary to provide a certain insulation distance (at least A dimension) between the cover and the top cover and the internal device such as the compressor.
In this case, there is a problem that the size of the air conditioner body frame that houses the internal equipment is limited by the above-described insulation distance, and the entire outer shell becomes large.
Therefore, by making the side cover made of synthetic resin such as FRP, the regulations of the withstand voltage test of JIS standard can be cleared. Between the side cover made of resin and the air conditioner body frame, or between the side cover and the mounting foot. The gap dimension is set to B dimension, so that the gap dimension for insulation is not required, and the outer diameter dimension including the side cover can be greatly reduced (for example, see Patent Document 1).
従来の車両用空気調和装置の外殻を構成するのは空調装置本体枠と上面カバーと側面カバーの他に、端面カバーに相当する妻カバーもあり、端面カバーが金属製で形成されている場合には、空調装置本体枠と端面カバーとの間に、一定の絶縁空間距離（少なくともＡ寸法）を設ける必要があり、そのため、内部機器を収納する空調装置本体枠のサイズが前述の絶縁空間距離に制約され、車両用空気調和装置のレール方向長さが大きくなるという問題があった。
また、端面カバーが合成樹脂製の場合には、端面カバーと空調装置本体枠との間に、絶縁のための隙間寸法を必要とせず、車両用空気調和装置のレール方向長さが端面カバーが金属製の場合に比べて小さくて済むが、端面カバーの存在により、車両用空気調和装置のレール方向長さを小さくするには限界があるという問題があった。
そこで、車両用空気調和装置の小型化および軽量化を考慮し、端面カバーを廃止することも考えられるが、端面カバーを廃止したとしても、ＪＩＳ規格の電車用ユニットクーラーＥ６６０２に定められている耐電圧試験に合格する必要がある。
加えて、端面カバーを廃止すると、空気調和装置本体枠と側面カバーの間に隙間ができ、外観を損ねるという問題があった。
本発明はかかる問題を解決するためになされたもので、車両用空気調和装置のレール方向長さを小さくし、ＪＩＳ規格の電車用ユニットクーラーＥ６６０２に定められている耐電圧試験に合格し、しかも空気調和装置本体枠と側面カバーの間に隙間を埋めて外観を損ねることがない車両用空気調和装置を得ることを目的とする。
In addition to the air conditioner body frame, top cover, and side cover, there is a wife cover that corresponds to the end cover, and the end cover is made of metal. Therefore, it is necessary to provide a certain insulating space distance (at least A dimension) between the air conditioner main body frame and the end surface cover. Therefore, the size of the air conditioner main body frame for housing the internal device is the above-described insulating space distance. There is a problem that the length of the vehicle air conditioner in the rail direction becomes large.
In addition, when the end cover is made of synthetic resin, there is no need for a gap dimension for insulation between the end cover and the air conditioner body frame, and the length of the vehicle air conditioner in the rail direction is the length of the end cover. Although it may be smaller than that made of metal, there is a problem that there is a limit to reducing the length in the rail direction of the vehicle air conditioner due to the presence of the end face cover.
Therefore, considering the miniaturization and weight reduction of the vehicle air conditioner, it may be possible to abolish the end face cover, but even if the end face cover is abolished, the JIS standard electric train unit cooler E6602 Must pass the voltage test.
In addition, if the end face cover is abolished, there is a problem that a gap is formed between the air conditioner main body frame and the side cover, and the appearance is impaired.
The present invention has been made to solve such a problem. The length of the vehicle air conditioner in the rail direction is reduced, and it passes the withstand voltage test defined in the JIS standard electric unit cooler E6602. An object is to obtain a vehicle air conditioner that does not impair the appearance by filling a gap between the air conditioner main body frame and the side cover.
本発明の車両用空気調和装置は、空調装置本体枠と、上面カバー及び側面カバーとから外殻を構成し、前記外殻の内部に圧縮機、熱交換器、及び室内送風機が設けられている車両用空気調和装置であって、前記空調装置本体枠の端面に端面カバーを設けずに、絶縁シートを貼付又は絶縁塗料を塗布して絶縁塗装膜を形成して構成されている。 In the vehicle air conditioner of the present invention, an outer shell is constituted by an air conditioner body frame, an upper surface cover, and a side cover, and a compressor, a heat exchanger, and an indoor fan are provided inside the outer shell. An air conditioner for a vehicle is configured by applying an insulating sheet or applying an insulating paint to form an insulating coating film without providing an end face cover on the end face of the air conditioner body frame.
本発明に係る車両用空気調和装置は、空調装置本体枠と、上面カバー及び側面カバーとから外殻を構成した車両用空気調和装置であって、前記空調装置本体枠の端面に絶縁シートを貼付又は絶縁塗料を塗布して絶縁塗装膜を形成しているので、端面カバーがない分、車両用空気調和装置のレール方向長さを小さくすることができ、その分のスペースの有効利用ができると共に車両用空気調和装置を軽量化することができ、しかも空調装置本体枠と端面カバーとの間に必要な絶縁空間距離を設けなくともＪＩＳ規格の耐圧試験を合格することができるという効果がある。
また、空調装置本体枠の端面に絶縁フィルムを貼付又は絶縁塗料を塗布して絶縁塗装膜を形成するようにしているので、端面カバーの取り付け作業を行わないため、車両用空気調和装置の組立作業の効率化を図ることができるという効果もある。
An air conditioner for a vehicle according to the present invention is an air conditioner for a vehicle having an outer shell made up of an air conditioner body frame, an upper surface cover, and a side cover, and an insulating sheet is attached to an end surface of the air conditioner body frame. Or, since the insulating coating film is formed by applying insulating paint, the length in the rail direction of the vehicle air conditioner can be reduced by the absence of the end cover, and the space can be used effectively. The vehicle air conditioner can be reduced in weight, and the JIS standard pressure test can be passed without providing the necessary insulation space distance between the air conditioner body frame and the end cover.
In addition, since an insulating coating film is formed by applying an insulating film or applying an insulating paint to the end face of the air conditioner main body frame, the installation work of the end face cover is not performed. There is also an effect that it is possible to improve efficiency.
