実施の形態１．
図１〜３は実施の形態１を示す図で、図１は空気調和機の室外機の斜視図、図２は空気調和機の室外機の正面図、図３は図２のＺ−Ｚ断面図である。
図１において、室外機は圧縮機、冷媒回路、及び電気部品を収納する機械室５を下部に設け、その上部に熱交換器２や送風機３が配置される送風室６を備える。熱交換器２は平面形状がＬ字状のものを２個組み合わせたものであり、全体で四角筒形状をなしている。 Embodiment 1 FIG.
1 to 3 are diagrams showing Embodiment 1, FIG. 1 is a perspective view of an outdoor unit of an air conditioner, FIG. 2 is a front view of the outdoor unit of the air conditioner, and FIG. 3 is a ZZ cross section of FIG. FIG.
In FIG. 1, the outdoor unit is provided with a machine room 5 that houses a compressor, a refrigerant circuit, and electrical components in a lower part, and a blower room 6 in which a heat exchanger 2 and a blower 3 are arranged. The heat exchanger 2 is a combination of two L-shaped planar shapes, and has a square tube shape as a whole.

室外機の側面は鋼板パネル７にて囲まれており、各部品を固定し剛性を確保している。   The side surface of the outdoor unit is surrounded by a steel plate panel 7, and each part is fixed to ensure rigidity.

また、熱交換器２周辺における鋼板パネル７の４つの側面は空気吸い込み口１となるが、この空気吸い込み口１に任意の個数の吸込みパネル８が設けられる。吸込みパネル８には、複数個の開口部９が設けられる。   The four side surfaces of the steel plate panel 7 around the heat exchanger 2 serve as the air suction port 1, and an arbitrary number of suction panels 8 are provided in the air suction port 1. The suction panel 8 is provided with a plurality of openings 9.

吸込みパネル８を設けない空気吸い込み口１は、例えばワイヤーガード等で構成される。   The air suction port 1 not provided with the suction panel 8 is constituted by, for example, a wire guard.

次に動作について説明する。
このように構成された空気調和室外機において、送風機３を駆動させると送風室６は負圧となり、空気吸い込み口１から吸込まれた空気は熱交換器２を通過して熱交換され、温度変化を伴った空気となって送風機３を通過して室外機上方へ送風される。 Next, the operation will be described.
In the air conditioner outdoor unit configured as described above, when the blower 3 is driven, the blower chamber 6 has a negative pressure, and the air sucked from the air suction port 1 passes through the heat exchanger 2 and is heat-exchanged to change the temperature. Is passed through the blower 3 and blown upward to the outdoor unit.

図２に示すように、吸込みパネル８に設けられる複数の開口部９の中、送風機３に近い領域の開口部９の形状を、内側に傾斜したベーン形状１０としている。   As shown in FIG. 2, the shape of the opening 9 in the region near the blower 3 among the plurality of openings 9 provided in the suction panel 8 is a vane shape 10 inclined inward.

これにより、図３に示すように、送風機からの音１１が熱交換器２を通過し、ベーン形状１０にて反射し、外部に漏れないようにすることができる。   Thereby, as shown in FIG. 3, the sound 11 from the blower can pass through the heat exchanger 2, be reflected by the vane shape 10, and not leak outside.

図２、３では、送風機３に近い領域の開口部９の形状を、内側に傾斜したベーン形状１０とした開口部９を有する吸込みパネル８を、熱交換器２周辺における鋼板パネル７の対向する２つの空気吸い込み口１に設けたものを示したが、吸込みパネル８の個数は任意でよい。吸込みパネル８を設けた方向の騒音が低下する。吸込みパネル８を設けない空気吸い込み口１は、前述のようにワイヤーガード等で構成する。   In FIGS. 2 and 3, the suction panel 8 having the opening 9 in which the shape of the opening 9 in the region close to the blower 3 is the vane shape 10 inclined inward is opposed to the steel plate panel 7 around the heat exchanger 2. Although what was provided in the two air suction inlets 1 was shown, the number of the suction panels 8 may be arbitrary. Noise in the direction in which the suction panel 8 is provided is reduced. The air inlet 1 without the suction panel 8 is constituted by a wire guard or the like as described above.

以上のように、送風機３から発生した騒音を、吸込みパネル８のベーン形状１０で反射させることにより熱交換器２を通過して外部に漏れる割合を抑制でき、かつ風量を確保できる開口部９形状にしているので、送風機３から発生する騒音の漏れを低減させることが可能となる。   As described above, the noise generated from the blower 3 is reflected by the vane shape 10 of the suction panel 8 so that the ratio of leaking to the outside through the heat exchanger 2 can be suppressed and the air flow rate 9 can be secured. Therefore, noise leakage generated from the blower 3 can be reduced.

実施の形態２．
図４〜６は実施の形態２を示す図で、図４は空気調和機の室外機の斜視図、図５は空気調和機の室外機の正面図、図６は図５のＹ−Ｙ断面図である。
上記実施の形態１では、送風機３に近い領域の開口部９の形状をベーン形状１０としたが、開口部面積を変化させた場合にも同等な効果を確保することができる。 Embodiment 2. FIG.
4 to 6 are diagrams showing Embodiment 2, FIG. 4 is a perspective view of the outdoor unit of the air conditioner, FIG. 5 is a front view of the outdoor unit of the air conditioner, and FIG. 6 is a YY cross section of FIG. FIG.
In Embodiment 1 described above, the shape of the opening 9 in the region close to the blower 3 is the vane shape 10, but the same effect can be ensured even when the area of the opening is changed.

図４〜６に示すように、吸込みパネル８に設けられている開口部９は、送風機３に近い領域の開口面積を送風機３に遠い領域の開口面積よりも小さな形状としている。その他の構成は、実施の形態１と同様であり、説明は省略する。   As shown in FIGS. 4 to 6, the opening 9 provided in the suction panel 8 has an opening area in a region near the blower 3 smaller than an opening area in a region far from the blower 3. Other configurations are the same as those in the first embodiment, and a description thereof will be omitted.

図６に示すように、送風機からの音１１は、熱交換器２を通過し、送風機３に近い開口部面積が小さい領域の吸込みパネル１２で反射させることが可能となる。   As shown in FIG. 6, the sound 11 from the blower can pass through the heat exchanger 2 and be reflected by the suction panel 12 in a region having a small opening area close to the blower 3.

図５、６では、送風機３に近い領域の開口部９の開口面積を送風機３に遠い領域の開口部９の開口面積よりも小さな形状とした吸込みパネル８を、熱交換器２周辺における鋼板パネル７の対向する２つの空気吸い込み口１に設けたものを示したが、実施の形態１と同様、吸込みパネル８の個数は任意でよい。吸込みパネル８を設けた方向の騒音が低下する。吸込みパネル８を設けない空気吸い込み口１は、前述のようにワイヤーガード等で構成する。   5 and 6, the suction panel 8 in which the opening area of the opening 9 in the region near the blower 3 is smaller than the opening area of the opening 9 in the region far from the blower 3 is a steel plate panel around the heat exchanger 2. 7, the two air suction ports 1 opposed to each other are shown. However, the number of the suction panels 8 may be arbitrary as in the first embodiment. Noise in the direction in which the suction panel 8 is provided is reduced. The air inlet 1 without the suction panel 8 is constituted by a wire guard or the like as described above.

以上のように、送風機３から発生した騒音が、送風機３に近い開口部面積が小さい領域の吸込みパネル１２で反射させて、熱交換器２を通過して漏れる割合を抑制でき、かつ風量を確保できる開口部９形状にしているので、送風機３から発生する騒音の漏れを低減させることが実施の形態１同様に可能となる。   As described above, the noise generated from the blower 3 is reflected by the suction panel 12 in a region having a small opening area close to the blower 3, and the rate of leakage through the heat exchanger 2 can be suppressed, and the air volume is secured. Since the shape of the opening 9 is made, it is possible to reduce the leakage of noise generated from the blower 3 as in the first embodiment.

実施の形態３．
図７〜９は実施の形態３を示す図で、図７は空気調和機の室外機の斜視図、図８は空気調和機の室外機の正面図、図９は図８のＸ−Ｘ断面図である。

これにより、図９に示すように、送風機からの音１１が熱交換器２を通過し、水平ベーン形状１５にて反射し、外部に漏れないようにすることができる。   As a result, as shown in FIG. 9, the sound 11 from the blower passes through the heat exchanger 2, is reflected by the horizontal vane shape 15, and can be prevented from leaking outside.

上記実施の形態１と比較した場合、水平ベーン形状１５の先端と熱交換器２との干渉が生じる恐れがある反面、開口部の面積は、実施の形態１のものより大きくなり、開口部面積を確保できる利点がある。   When compared with the first embodiment, there is a possibility that the tip of the horizontal vane shape 15 and the heat exchanger 2 may interfere with each other, but the area of the opening is larger than that of the first embodiment, and the area of the opening is larger. There is an advantage that can be secured.

図８、９では、送風機３に近い領域の開口部９の形状を、内側に直角にした水平ベーン形状１５とした開口部９を有する吸込みパネル８を、熱交換器２周辺における鋼板パネル７の対向する２つの空気吸い込み口１に設けたものを示したが、上記実施の形態と同様、吸込みパネル８の個数は任意でよい。吸込みパネル８を設けた方向の騒音が低下する。吸込みパネル８を設けない空気吸い込み口１は、前述のようにワイヤーガード等で構成する。   8 and 9, the suction panel 8 having the opening 9 in the horizontal vane shape 15 in which the shape of the opening 9 in the region close to the blower 3 is perpendicular to the inside is used for the steel plate panel 7 around the heat exchanger 2. Although what was provided in the two air suction inlets 1 which opposes was shown, the number of the suction panels 8 may be arbitrary similarly to the said embodiment. Noise in the direction in which the suction panel 8 is provided is reduced. The air inlet 1 without the suction panel 8 is constituted by a wire guard or the like as described above.

以上のように、送風機３から発生した騒音を、吸込みパネル８の水平ベーン形状１５で反射させることにより熱交換器２を通過して外部に漏れる割合を抑制でき、かつ風量を十分に確保できる開口部９形状にしているので、送風機３から発生する騒音の漏れを低減させることが可能となる。   As described above, the noise generated from the blower 3 is reflected by the horizontal vane shape 15 of the suction panel 8 so that the ratio of leaking outside through the heat exchanger 2 can be suppressed, and the air volume can be sufficiently secured. Since the shape of the portion 9 is adopted, it is possible to reduce noise leakage generated from the blower 3.
