Description

空気調和機の室外機Air conditioner outdoor unit
　本発明は空気調和機の室外機に関する。 The present invention relates to an outdoor unit of an air conditioner.
　従来、家屋用の空気調和機としては一般的にヒートポンプ方式が採用され、室外機と室内機とに分かれた分離型（セパレート型）が主流である。屋外に室外機が配置され、屋内には室内機が配置され、家屋の外壁を貫通する冷媒配管で室外機と室内機とが接続される。空気調和機の室外機に係る技術が特許文献１に開示されている。 Conventionally, a heat pump system is generally adopted as an air conditioner for a house, and a separate type (separate type) divided into an outdoor unit and an indoor unit has been mainstream. An outdoor unit is arranged outdoors, an indoor unit is arranged indoors, and the outdoor unit and the indoor unit are connected by a refrigerant pipe penetrating the outer wall of the house. A technique related to an outdoor unit of an air conditioner is disclosed in Patent Document 1.
　特許文献１に記載された従来の空気調和機はケーシングと、空気熱交換器と、軸流ファンと、ファンモータと、ファンガードと、を備える。軸流ファンはケーシングの空気の吹き出し口である空気流通口に臨み、ファンモータによって回転される。ファンガードは空気流通口に固定される。そして、ファンモータがファンガードの内面に固定される。ファンモータがファンガードに直接取り付けられることで、別部材からなるモータ取付板を必要とせず、室外機のコストダウンを図ることができる。 The conventional air conditioner described in Patent Document 1 includes a casing, an air heat exchanger, an axial fan, a fan motor, and a fan guard. The axial fan faces an air circulation port which is an air outlet of the casing and is rotated by a fan motor. The fan guard is fixed to the air circulation port. The fan motor is fixed to the inner surface of the fan guard. By directly attaching the fan motor to the fan guard, it is possible to reduce the cost of the outdoor unit without requiring a motor mounting plate made of a separate member.
実開昭６２－１０５４３３号公報Japanese Utility Model Publication Sho 62-105433
　近年、空気調和機の室外機のケーシングは、底面と、上面と、４個の側面とを組み合わせた構成を有している。そして、特許文献１に記載された従来の空気調和機の室外機のように、ファンガードに対して、ファンモータを直接取り付けると、ケーシングのファンガードが取り付けられる側面でモータを支持する。そして、ファンモータが駆動による振動も、ファンガードが取り付けられる側面に作用する。従来のケーシングの側面は、荷重や振動に耐える、すなわち、強度部材としての役割を果たしていない。 Recently, the casing of an outdoor unit of an air conditioner has a configuration in which a bottom surface, a top surface, and four side surfaces are combined. And if a fan motor is directly attached with respect to a fan guard like the conventional outdoor unit of the air conditioner described in patent document 1, a motor will be supported by the side surface to which the fan guard of a casing is attached. And the vibration by a fan motor drive also acts on the side surface to which a fan guard is attached. The side surface of the conventional casing resists loads and vibrations, that is, does not play a role as a strength member.
　そのため、ケーシングの側面に、ファンモータが取り付けられ、その荷重、振動、推力が側面に作用する。その結果、側面の固定が外れて、側面が筐体から分離し、脱落することがある。また、側面の筐体からの脱落により、ファンモータ及び軸流ファンが落下して、ファンモータ及び軸流ファンが破損するおそれがある。 Therefore, a fan motor is attached to the side surface of the casing, and its load, vibration, and thrust act on the side surface. As a result, the fixing of the side surface is released, and the side surface may be separated from the housing and fall off. Moreover, the fan motor and the axial fan may fall due to the side surface falling off from the casing, and the fan motor and the axial fan may be damaged.
　本発明は、上記の点に鑑みなされたものであり、室外機の薄型化を図りながら、ファンモータの脱落を抑制することができる空気調和機の室外機を提供することを目的とする。 This invention is made in view of said point, and it aims at providing the outdoor unit of the air conditioner which can suppress drop-off | omission of a fan motor, aiming at thickness reduction of an outdoor unit.
　本発明の例示的な空気調和機の室外機は、筐体と、前記筐体の内側に配置されたファンモータとを備え、前記筐体は、底部材と、前記底部材から鉛直方向に伸びる前壁とを有しており、前記前壁は、前記前壁を貫通する通気孔を有する通風部を有し、前記ファンモータは、前記通風部に取り付けられ、前記前壁は、前記底部材と単一の部材である。 An exemplary outdoor unit of an air conditioner according to the present invention includes a housing and a fan motor disposed inside the housing, and the housing extends in a vertical direction from the bottom member and the bottom member. A front wall, the front wall has a ventilation portion having a vent hole penetrating the front wall, the fan motor is attached to the ventilation portion, and the front wall is the bottom member And a single member.
　例示的な本発明の空気調和機の室外機によれば、室外機の薄型化を図りながら、ファンモータの脱落を抑制することができる。 According to the outdoor unit of an air conditioner of the present invention, it is possible to suppress the fan motor from falling off while reducing the thickness of the outdoor unit.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view showing an appearance of an outdoor unit of an air conditioner according to the present invention. FIG. 2 is a front view of the outdoor unit of the air conditioner shown in FIG. 3 is an exploded perspective view of the outdoor unit of the air conditioner shown in FIG.
＜１．１　空気調和機の室外機の概略構成＞
　室外機１は、不図示の室内機との組み合わせで構成される分離型の空気調和機の室外機である。室外機１は、例えばベランダ、屋上等の屋外の床面上に設置される。図３に示すように、室外機１は、筐体２と、通風部４と、電源部５と、圧縮機６と、熱交換器７と、ファンモータ８とを備えている。そして、室外機１において、電源部５と、圧縮機６と、熱交換器７と、ファンモータ８とは、筐体２の内部に配置される。すなわち、空気調和機の室外機１は、筐体２と、筐体２の内側に配置されたファンモータ８とを備えている。 <1.1 Outline configuration of outdoor unit of air conditioner>
The outdoor unit 1 is an outdoor unit of a separation type air conditioner configured by a combination with an indoor unit (not shown). The outdoor unit 1 is installed on an outdoor floor such as a veranda or a rooftop. As shown in FIG. 3, the outdoor unit 1 includes a housing 2, a ventilation unit 4, a power supply unit 5, a compressor 6, a heat exchanger 7, and a fan motor 8. In the outdoor unit 1, the power supply unit 5, the compressor 6, the heat exchanger 7, and the fan motor 8 are disposed inside the housing 2. That is, the outdoor unit 1 of an air conditioner includes a housing 2 and a fan motor 8 disposed inside the housing 2.
　筐体２は、箱型である。筐体２は、例えば、合成樹脂部品と板金部品とで構成される。しかしながら、これに限定されるものではなく、合成樹脂部品で全体を構成してもよいし、板金部品で全体を構成してもよい。また、これら以外の材料で構成してもよい。筐体２は外部に配置されるものであり、雨、風、日照等の天候の変化から、内部の物品を保護できる構成を広く採用できる。 The housing 2 has a box shape. The housing 2 is composed of, for example, a synthetic resin part and a sheet metal part. However, the present invention is not limited to this, and the whole may be composed of synthetic resin parts, or the whole may be composed of sheet metal parts. Moreover, you may comprise with materials other than these. The housing 2 is arranged outside, and a configuration that can protect internal articles from weather changes such as rain, wind, and sunshine can be widely adopted.
　図３に示すように、筐体２は、底部材２１と、前壁２２と、一対の側壁２３および２４と、背面板２５と、天面板２６とを有している。筐体２の詳細については、後述する。 As shown in FIG. 3, the housing 2 includes a bottom member 21, a front wall 22, a pair of side walls 23 and 24, a back plate 25, and a top plate 26. Details of the housing 2 will be described later.
　電源部５は、例えば筐体２の内部に設置される不図示の支持部に支持される。電源部５は、外部の商用電源等から電力供給を受けて、室外機１が動作するために必要な電圧を生成する。電源部５は、不図示の電気回路等を用いて整流、降圧、昇圧等を行って室外機１で用いられる各種電圧を生成する。電源部５は、室外機１の各構成要素に電力を供給する。 The power supply unit 5 is supported by a support unit (not shown) installed inside the housing 2, for example. The power supply unit 5 receives power supply from an external commercial power supply or the like, and generates a voltage necessary for the outdoor unit 1 to operate. The power source unit 5 generates various voltages used in the outdoor unit 1 by performing rectification, step-down, step-up, and the like using an electric circuit (not shown). The power supply unit 5 supplies power to each component of the outdoor unit 1.
　圧縮機６は、筐体２の底板２１の上面に設置される。圧縮機６は、冷凍サイクルで用いる冷媒を圧縮し、高温高圧気体の冷媒を生成する。圧縮機６が吐出する冷媒は、室外機１の熱交換器７および室内機が収容する熱交換器（不図示）に送られる。 The compressor 6 is installed on the upper surface of the bottom plate 21 of the housing 2. The compressor 6 compresses the refrigerant used in the refrigeration cycle, and generates a high-temperature and high-pressure gaseous refrigerant. The refrigerant discharged from the compressor 6 is sent to a heat exchanger 7 of the outdoor unit 1 and a heat exchanger (not shown) accommodated in the indoor unit.
　熱交換器７は、筐体２の底板２１の上面に設置される。熱交換器７は、筐体２の側壁２３および背面板２５に設けられた吸込口２８に隣接して配置される。ファンモータ８を駆動すると、外部から吸込口２８を通って筐体２の内部に吸い込まれた外気が熱交換器７を通過する。熱交換器７は、筐体２の内部に吸い込まれた外気との間で熱交換を行う。例えば、空気調和機が冷房運転のとき、熱交換器７に流入した冷媒は、吸込口２８から吸い込まれた外気に熱を渡す。また、空気調和機が暖房運転のとき、熱交換器７に流入した冷媒は、吸込口２８から吸い込まれた外気から熱を奪う。 The heat exchanger 7 is installed on the upper surface of the bottom plate 21 of the housing 2. The heat exchanger 7 is disposed adjacent to the suction port 28 provided in the side wall 23 and the back plate 25 of the housing 2. When the fan motor 8 is driven, the outside air sucked into the housing 2 from the outside through the suction port 28 passes through the heat exchanger 7. The heat exchanger 7 exchanges heat with the outside air sucked into the housing 2. For example, when the air conditioner is in a cooling operation, the refrigerant that has flowed into the heat exchanger 7 transfers heat to the outside air sucked from the suction port 28. Further, when the air conditioner is in the heating operation, the refrigerant that has flowed into the heat exchanger 7 takes heat from the outside air sucked from the suction port 28.
　ファンモータ８は、筐体２の内側に配置される。ファンモータ８は、その回転軸線を略水平にして配置される。ファンモータ８は、インペラ８１と、これを回転させるモータ８２とを組み合わせたものである。ファンモータ８は、後述の通風部４を介して、前壁２２の後述する開口部２２１に取り付けられる。ファンモータ８は、後述の図５等に示すように、モータ８２の回転によってインペラ８１を回転させて、軸線方向の気流を発生させる。空気調和機の室外機１において、インペラ８１の回転によって発生する気流は、開口部２２１から外部に流出する方向である。 The fan motor 8 is disposed inside the housing 2. The fan motor 8 is arranged with its rotation axis substantially horizontal. The fan motor 8 is a combination of an impeller 81 and a motor 82 that rotates the impeller 81. The fan motor 8 is attached to an opening 221 (described later) of the front wall 22 through a ventilation unit 4 (described later). As shown in FIG. 5 and the like described later, the fan motor 8 rotates the impeller 81 by the rotation of the motor 82 to generate an airflow in the axial direction. In the outdoor unit 1 of the air conditioner, the air flow generated by the rotation of the impeller 81 is a direction that flows out from the opening 221 to the outside.
　その他、室外機１は、不図示の四方弁、膨張弁等の構成要素を備える。四方弁は、冷房運転時、暖房運転時などの異なる運転モードにおいて冷媒の流通方向を切り替えるために設けられる。膨張弁には、開度制御の可能なものが用いられる。 In addition, the outdoor unit 1 includes components such as a four-way valve and an expansion valve (not shown). The four-way valve is provided to switch the refrigerant flow direction in different operation modes such as cooling operation and heating operation. As the expansion valve, a valve whose opening degree can be controlled is used.
＜１．２　筐体の構成＞
　続いて、室外機１の筐体２の詳細について、図面を参照して説明する。底部材２１は、板金部材であり、長方形状の板材である。上述のとおり、圧縮機６および熱交換器７が底部材２１の上面に固定される。 <1.2 Case configuration>
Next, details of the housing 2 of the outdoor unit 1 will be described with reference to the drawings. The bottom member 21 is a sheet metal member and is a rectangular plate material. As described above, the compressor 6 and the heat exchanger 7 are fixed to the upper surface of the bottom member 21.
　本実施形態にかかる底部材２１および前壁２２は、いずれも、長方形状の板金部材である。前壁２２は、底部材２１と単一の部材で形成されている。すなわち、底部材２１と前壁２２とは、単一の部材で形成されている。なお、ここで、底部材２１と前壁２２とを単一の部材で形成するとは、底部材２１と前壁２２とを同一の材料で、同一の部材として形成することである。すなわち、底部材２１と前壁２２とを一体として形成することである。以下の説明において、２つの部材が、単一の部材であるとの記載がある場合、上述と同様に、２つの部材を一体として形成していることを指す。 The bottom member 21 and the front wall 22 according to the present embodiment are both rectangular sheet metal members. The front wall 22 is formed of the bottom member 21 and a single member. That is, the bottom member 21 and the front wall 22 are formed of a single member. Here, forming the bottom member 21 and the front wall 22 as a single member means that the bottom member 21 and the front wall 22 are formed of the same material and as the same member. That is, the bottom member 21 and the front wall 22 are integrally formed. In the following description, when there is a description that two members are a single member, it means that the two members are integrally formed as described above.
　本実施形態において、底部材２１および前壁２２は、１枚の金属板（板金）から形成される。図４は、図３に示す筐体の底部材と前壁とを形成する金属板である。図４に示す金属板３は、鋼製の平板、いわゆる、板金である。金属板３は、長方形状の第１領域３１と、長方形状の第２領域３２とを有している。そして、第１領域３１は長辺で、第２領域３２と隣り合う。つまり、第１領域３１の長辺が境界線Ｂ１である。金属板３を、境界線Ｂ１で折り曲げて、底部材２１および前壁２２が、形成される。なお、第１領域３１が底部材２１になる領域であり、第２領域３２が前壁２２になる領域である。つまり、金属板３において、「領域」は、「面」である。また、金属板３には、第２領域３２に円形の貫通孔３２０が形成されている。この貫通孔３２０が、前壁２２の開口部２２１である。この貫通孔３２０は、折り曲げる前に形成してもよいし、折り曲げ加工と同時に形成してもよい。また、折り曲げ後に形成してもよい。また、図示は省略しているが、貫通孔３２０の隣に、リブ２７となる部分が形成される。 In the present embodiment, the bottom member 21 and the front wall 22 are formed from a single metal plate (sheet metal). 4 is a metal plate that forms the bottom member and the front wall of the housing shown in FIG. The metal plate 3 shown in FIG. 4 is a steel flat plate, a so-called sheet metal. The metal plate 3 has a rectangular first region 31 and a rectangular second region 32. The first region 31 has a long side and is adjacent to the second region 32. That is, the long side of the first region 31 is the boundary line B1. The bottom plate 21 and the front wall 22 are formed by bending the metal plate 3 at the boundary line B1. The first region 31 is a region that becomes the bottom member 21, and the second region 32 is a region that becomes the front wall 22. That is, in the metal plate 3, the “region” is a “surface”. The metal plate 3 is formed with a circular through hole 320 in the second region 32. This through hole 320 is the opening 221 of the front wall 22. The through hole 320 may be formed before being bent or may be formed simultaneously with the bending process. Moreover, you may form after bending. Although not shown, a portion that becomes the rib 27 is formed next to the through hole 320.
　金属板３を折り曲げるときの、第１領域３１と第２領域３２とがなす角度は、直角より小さいことが好ましい。なぜなら、金属板３は、弾性変形による戻りが発生するためである。また、側壁２３および側壁２４を取り付けたときに、弾性力で、前壁２２を側壁２３および側壁２４に押し付ける。これにより、筐体２の剛性を高めることができる。 The angle formed by the first region 31 and the second region 32 when the metal plate 3 is bent is preferably smaller than a right angle. This is because the metal plate 3 returns due to elastic deformation. Further, when the side wall 23 and the side wall 24 are attached, the front wall 22 is pressed against the side wall 23 and the side wall 24 by an elastic force. Thereby, the rigidity of the housing | casing 2 can be improved.
　第１領域３１には、境界線Ｂ１の隣の両辺に設けられた、一対の第１継ぎしろ３１１が形成されている。第１継ぎしろ３１１は、長方形状の板材である。一対の第１継ぎしろ３１１は、第１領域３１に対して折り曲げられる。第１継ぎしろ３１１は、底部材２１の短辺から鉛直方向に起立した一対の側部取付部材２１１となる。すなわち、底部材２１は側部取付部材２１１を有している。そして、側部取付部材２１１は、底部材２１と単一の部材となっている。また、第１領域３１の境界線Ｂ１と反対側の長辺には、第２継ぎしろ３１２が設けられている。第２継ぎしろ３１２も、第１領域３１に対して折り曲げられる。第２継ぎしろ３１２は、底部材２１の長辺から鉛直方向に起立した背面取付部材２１２となる。 In the first region 31, a pair of first joints 311 provided on both sides adjacent to the boundary line B1 are formed. The first joint 311 is a rectangular plate material. The pair of first joining margins 311 is bent with respect to the first region 31. The first joint 311 serves as a pair of side attachment members 211 erected in the vertical direction from the short side of the bottom member 21. That is, the bottom member 21 has a side attachment member 211. The side attachment member 211 is a single member with the bottom member 21. A second joint 312 is provided on the long side of the first region 31 opposite to the boundary line B1. The second joining margin 312 is also bent with respect to the first region 31. The second joint 312 serves as a back surface mounting member 212 that stands in the vertical direction from the long side of the bottom member 21.
　底部材２１は、下面に設けられた２個の脚部２０を有している。すなわち、底部材２１は、下面に設けられた脚部２０を有している。脚部２０は、底部材２１の長手方向の両端の近傍に設けられており、脚部２０は、底部材２１の短辺よりも長い長尺状である。脚部２０は、底部材２１を鉛直方向に見たとき、底部材２１の長辺から突出した部分を有している。脚部２０を備えていることで、空気調和機の室外機２が、底部材２１の短手方向に倒れにくくなる。脚部２０は、一面が開口する箱型であってもよいし、板状或いは棒状の部材であってもよい。なお、空気調和機の室外機２では、設置面に配置された設置台（不図示）の上に配置されることが多い。このような場合、脚部２０は、設置台に固定される。 The bottom member 21 has two legs 20 provided on the lower surface. That is, the bottom member 21 has the leg part 20 provided in the lower surface. The leg portion 20 is provided in the vicinity of both ends in the longitudinal direction of the bottom member 21, and the leg portion 20 has a long shape longer than the short side of the bottom member 21. The leg portion 20 has a portion protruding from the long side of the bottom member 21 when the bottom member 21 is viewed in the vertical direction. By providing the leg portion 20, the outdoor unit 2 of the air conditioner is less likely to fall in the short direction of the bottom member 21. The leg portion 20 may be a box shape with one surface open, or may be a plate-shaped or bar-shaped member. In addition, in the outdoor unit 2 of an air conditioner, it is often arranged on an installation table (not shown) arranged on the installation surface. In such a case, the leg portion 20 is fixed to the installation base.
　前壁２２は、長方形状の板材である。前壁２２は、底部材２１の一方の長辺と接続され、底部材２１と直角をなす。すなわち、筐体２は、底部材２１と、底部材２１から鉛直方向に延びる前壁２２とを有している。 The front wall 22 is a rectangular plate material. The front wall 22 is connected to one long side of the bottom member 21 and forms a right angle with the bottom member 21. That is, the housing 2 includes a bottom member 21 and a front wall 22 extending from the bottom member 21 in the vertical direction.

The front wall 22, the front rib 231 and the front rib 241 are fixed using a fixing member Fp. Here, the fixing member Fp may be a screw, but is not limited thereto. For example, rivets, screw rivets, push rivets and the like can be mentioned. Moreover, you may fix by fixing structures, such as welding and brazing, without using the fixing member Fp. A structure that can fix the front wall 22, the front rib 231 and the front rib 241 can be widely employed.
　前壁２２には、上下方向または左右方向に延びる凹凸であるリブ２７が設けられている。リブ２７を設けることで、筐体２自体の揺れ、共振を抑制する。例えば、リブ２７が、上下方向延びる構成の場合、筐体２が、上下方向の中間部分で折れるのを抑制することができる。リブ２７が前壁２２の上端から下端まで到達する形状であってもよい。また、リブ２７が左右方向に延びる構成の場合、圧縮機６やファンモータ８の振動の側壁２３、２４への、伝播を抑制することができる。リブ２７が前壁２２の左端から右端まで到達する形状であってもよい。 The front wall 22 is provided with ribs 27 that are unevenness extending in the vertical direction or the horizontal direction. Providing the ribs 27 suppresses shaking and resonance of the housing 2 itself. For example, when the rib 27 is configured to extend in the vertical direction, the casing 2 can be prevented from being bent at an intermediate portion in the vertical direction. The rib 27 may have a shape that reaches from the upper end to the lower end of the front wall 22. Further, when the rib 27 extends in the left-right direction, propagation of vibrations of the compressor 6 and the fan motor 8 to the side walls 23 and 24 can be suppressed. The rib 27 may have a shape that reaches from the left end to the right end of the front wall 22.

Then, the ventilation part 4 is demonstrated with reference to drawings. FIG. 5 is a rear view showing a state in which a fan motor is attached to the ventilation portion. FIG. 6 is a cross-sectional view showing a state where the fan motor is attached to the ventilation portion. In addition, in FIG. 6, since the fan motor 8 shows the arrangement | positioning, it has shown schematic shape.
　通風部４は、前壁２２の開口部２２１を覆う。通風部４は、開口部２２１の形状に対応した円形である。通風部４の形状は、円形以外であっても良い。通風部４は、前壁２２とは別部材である。通風部４は、例えば合成樹脂で構成される。通風部４は、例えばねじ等の固定部材Ｆｐを用いて前壁２２に固定される。通風部４は、合成樹脂に限定されるものではなく、金属製であってもよい。通風部４は、ファンモータ８を支持することができる、剛性を有する構成を広く採用することができる。また、通風部４の前壁２２への固定は、ねじに限定されない。固定構造は、前壁２２と前リブ２３１および前リブ２４１との固定で示した固定構造のいずれかを利用してもよい。 The ventilation section 4 covers the opening 221 of the front wall 22. The ventilation part 4 has a circular shape corresponding to the shape of the opening 221. The shape of the ventilation part 4 may be other than circular. The ventilation part 4 is a separate member from the front wall 22. The ventilation part 4 is comprised, for example with a synthetic resin. The ventilation part 4 is fixed to the front wall 22 using a fixing member Fp such as a screw. The ventilation part 4 is not limited to a synthetic resin, and may be made of metal. The ventilation part 4 can widely employ a rigid structure that can support the fan motor 8. Moreover, fixation to the front wall 22 of the ventilation part 4 is not limited to a screw. As the fixing structure, any of the fixing structures shown by fixing the front wall 22 to the front rib 231 and the front rib 241 may be used.
　通風部４は、円板部４０と、リブ部４１と、ガード部４２と、通気孔４３とを備えている。円板部４０は、通風部４の中央に形成された円形部分である。円板部４０には、ファンモータ８が取り付けられる。すなわち、ファンモータ８は、通風部４に取り付けられる。ファンモータ８は、ここでは、ねじで固定されているが、これに限定されない。駆動時を含めて、ファンモータ８が円板部４０に対して移動しない固定構造を広く採用することができる。 The ventilation part 4 includes a disk part 40, a rib part 41, a guard part 42, and a vent hole 43. The disc part 40 is a circular part formed in the center of the ventilation part 4. A fan motor 8 is attached to the disc portion 40. That is, the fan motor 8 is attached to the ventilation part 4. Here, the fan motor 8 is fixed with screws, but is not limited thereto. A fixing structure in which the fan motor 8 does not move with respect to the disc portion 40 can be widely adopted including during driving.
　リブ部４１は、円板部４０から径方向に延びている。リブ部４１は複数個備えられており、周方向に等間隔に配列されている。そして、ガード部４２は、円板部４０の周囲に配置され、周方向に延びる。ガード部は複数個備えられており、径方向に配列されている。通気孔４３は、周方向に延び、通風部４を軸線方向に貫通している。つまり、通気孔４３は、通風部４で開口部２２１を覆ったとき、前壁２２を貫通している。通気孔４３は、ファンモータ８の駆動によって発生する空気が吹出す開口である。すなわち、前壁２２は、前壁２２を貫通する通気孔４３を有する通風部４を有する。そして、通風部４は、中央にファンモータ８が取り付けられるとともに、ファンモータ８の周囲に通気孔４３が設けられている。 The rib portion 41 extends in the radial direction from the disc portion 40.

And the guard part 42 is arrange | positioned around the disc part 40, and is extended in the circumferential direction. A plurality of guard portions are provided and arranged in the radial direction. The ventilation hole 43 extends in the circumferential direction and penetrates the ventilation portion 4 in the axial direction. That is, the vent hole 43 penetrates the front wall 22 when the opening 221 is covered with the ventilation portion 4. The vent hole 43 is an opening through which air generated by driving the fan motor 8 is blown. That is, the front wall 22 has the ventilation portion 4 having the vent holes 43 that penetrate the front wall 22. The ventilation section 4 is provided with a fan motor 8 at the center and a vent hole 43 around the fan motor 8.
　図５に示すように、リブ部４１とガード部４２とは、単一の部材で形成されている。つまり、通気孔４３は、リブ部４１と、ガード部４２とで囲まれている。なお、通風部４の形状は、これに限定されない。例えば、六角形状の通気孔４３が、２次元配列された構造、すなわち、ハニカム構造であってもよい。 As shown in FIG. 5, the rib part 41 and the guard part 42 are formed of a single member. That is, the vent hole 43 is surrounded by the rib portion 41 and the guard portion 42. In addition, the shape of the ventilation part 4 is not limited to this. For example, a structure in which hexagonal air holes 43 are two-dimensionally arranged, that is, a honeycomb structure may be used.
　図５に示すように、複数のリブ部４１及び複数のガード部４２を備えることで、通気孔４３から人の手指が筐体２の内部に入ることを抑制する。また、通風部４を用いることで、通風部４の外面と、ファンモータ８のインペラ８１との間の隙間Ｌを大きくすることができる。これにより、通気孔４３から人の手指が侵入した場合でも、手指がインペラ８１に接触しにくくなる。そのため、人の手指が傷つくのを抑制することができる。また、複数のリブ部４１及び複数のガード部４２は、通気孔４３から筐体２の内部に異物が混入することも抑制できる。 As shown in FIG. 5, by providing a plurality of rib portions 41 and a plurality of guard portions 42, it is possible to prevent human fingers from entering the inside of the housing 2 from the air holes 43. Moreover, by using the ventilation part 4, the clearance gap L between the outer surface of the ventilation part 4 and the impeller 81 of the fan motor 8 can be enlarged. Accordingly, even when a human finger enters the air hole 43, the finger is unlikely to contact the impeller 81. Therefore, it can suppress that a person's finger is damaged. Further, the plurality of rib portions 41 and the plurality of guard portions 42 can also prevent foreign matters from being mixed into the housing 2 through the air holes 43.
＜１．４　室外機の底部材および前壁の構成＞
　続いて、室外機１の底部材２１と前壁２２とについて説明する。図３に示すように、空気調和機の室外機１において、ファンモータ８は、通風部４に取り付けられる。そして、通風部４が、全面板２２に取り付けられる。このとき、通風部４は、開口部２２１の軸線方向の外側を覆う。すなわち、通風部４は、開口部２２１を覆っている。また、通風部４は、ねじ等の固定部材を用いて、前壁２２に対して、分離可能に取り付けられていてもよい。 <1.4 Configuration of bottom unit and front wall of outdoor unit>

As shown in FIG. 3, the fan motor 8 is attached to the ventilation unit 4 in the outdoor unit 1 of the air conditioner. And the ventilation part 4 is attached to the whole board 22. At this time, the ventilation part 4 covers the outer side of the opening part 221 in the axial direction. That is, the ventilation part 4 covers the opening part 221. Moreover, the ventilation part 4 may be detachably attached to the front wall 22 using a fixing member such as a screw.
　前壁２２に取り付けられた通風部４には、ファンモータ８が取り付けられている。そのため、前壁２２には、それ自体および通風部４に加えて、ファンモータ８の重量が作用する。また、ファンモータ８の駆動による振動や気流の発生による軸力も作用する。つまり、前壁２２と、側壁２３、側壁２４および天面板２５とを固定している固定部材Ｆｐに振動および力が作用する。そのため、これらの固定部材Ｆｐは外れやすくなる。 A fan motor 8 is attached to the ventilation portion 4 attached to the front wall 22. Therefore, the weight of the fan motor 8 acts on the front wall 22 in addition to itself and the ventilation part 4. Moreover, the axial force by the vibration by the drive of the fan motor 8 and generation | occurrence | production of an airflow acts. That is, vibration and force act on the fixing member Fp that fixes the front wall 22, the side wall 23, the side wall 24, and the top plate 25. Therefore, these fixing members Fp are easily detached.
　従来の室外機のように、前壁２２を底部材２１に固定部材で固定している構成の場合、底部材２１と前壁２２を固定している固定部材Ｆｐが外れる場合がある。そして、固定部材Ｆｐが外れると、前壁２２の下部が、底部材２１から外部に脱落し、前壁２２が、筐体２の内側に倒れる。このように、前壁２２が内側に倒れると、ファンモータ８が、筐体２の内部の構成要素と接触する。これにより、ファンモータ８のインペラ８１やモータ８２が破損してしまう場合がある。また、ファンモータ８が駆動状態であると、構成要素をインペラ８１またはモータ８２の回転子が、構成要素と衝突し、構成要素を破損してしまう。また、前壁２２は、下部が脱落したのち、外側に倒れる場合がある。ファンモータ８が駆動状態の場合、インペラ８１の回転で、人の手足を傷つけてしまう場合がある。また、筐体２の外部の物品に接触して、破損、破壊してしまうこともある。 In the case where the front wall 22 is fixed to the bottom member 21 with a fixing member as in a conventional outdoor unit, the fixing member Fp that fixes the bottom member 21 and the front wall 22 may come off. When the fixing member Fp is removed, the lower portion of the front wall 22 falls out of the bottom member 21, and the front wall 22 falls to the inside of the housing 2. As described above, when the front wall 22 falls inward, the fan motor 8 comes into contact with the components inside the housing 2. Thereby, the impeller 81 and the motor 82 of the fan motor 8 may be damaged. In addition, when the fan motor 8 is in a driving state, the impeller 81 or the rotor of the motor 82 collides with the constituent elements and damages the constituent elements. Further, the front wall 22 may fall outward after the lower part falls off. When the fan motor 8 is in a driving state, the rotation of the impeller 81 may injure human limbs. Moreover, it may be damaged or destroyed by contacting an article outside the housing 2.
　本実施形態にかかる空気調和機の室外機１では、底部材２１と前壁２２とが、単一の部材である。前壁２２を固定する固定部材Ｆｐの一部またはすべてが外れたとしても、前壁２２と底部材２１とが分離されない。これにより、固定部材Ｆｐの一部またはすべてが外れても、前壁２２の下部の、底部材２１からの脱落および前壁２２が倒れるのを抑制できる。これにより、ファンモータ８自体の破損、筐体２の内部の構成要素の破損および人の手足を傷つけるのを抑制することができる。 In the outdoor unit 1 of the air conditioner according to the present embodiment, the bottom member 21 and the front wall 22 are a single member. Even if a part or all of the fixing member Fp for fixing the front wall 22 is removed, the front wall 22 and the bottom member 21 are not separated. Thereby, even if a part or all of the fixing member Fp is detached, it is possible to prevent the lower portion of the front wall 22 from falling off the bottom member 21 and the front wall 22 from falling. Thereby, it is possible to suppress damage to the fan motor 8 itself, damage to the internal components of the housing 2, and damage to human limbs.
　つまり、本実施形態にかかる空気調和機の室外機１は、ファンモータ８を通風部４を介して、前壁２２に取り付けるため、室外機１を薄型化できる。そして、前壁、すなわち、前壁２２を、底部材、すなわち、底部材２１と単一の部材として構成することで、ファンモータ８の脱落を抑制できる。つまり、空気調和機の室外機を薄型化しつつ、ファンモータ８の脱落を抑制できる。 That is, since the outdoor unit 1 of the air conditioner according to the present embodiment is attached to the front wall 22 through the ventilation unit 4 of the fan motor 8, the outdoor unit 1 can be thinned. Then, the front wall, that is, the front wall 22 is configured as a bottom member, that is, the bottom member 21 and a single member, so that the fan motor 8 can be prevented from falling off. In other words, the fan motor 8 can be prevented from falling off while reducing the thickness of the outdoor unit of the air conditioner.
　なお、本実施形態にかかる筐体２は、板金部材を組み合わせたものとしているが、これに限定されない。例えば、合成樹脂の成型体であってもよい。 In addition, although the housing | casing 2 concerning this embodiment shall be the thing which combined the sheet metal member, it is not limited to this. For example, it may be a molded body of synthetic resin.
＜２．第２実施形態＞
＜２．１　室外機の筐体の構成＞
　次に、本発明の例示的な第２実施形態の空気調和機の室外機について説明する。図７は、本発明にかかる空気調和機の室外機の他の例の正面図である。図８は、図７に示す空気調和機の室外機の筐体の製造前の金属板を示す図である。図９は、図８に示す金属板を組み立てた状態を背面側から見た斜視図である。なお、本実施形態の空気調和機の室外機１Ｂの、基本的な構成は先に説明した第１実施形態の室外機１と同じである。そのため、本実施形態の室外機１Ｂの、第１実施形態の室外機１と共通する部分には、同じ符号を付す。また、実質上、同じ部分の説明は、省略する。 <2. Second Embodiment>
<2.1 Configuration of outdoor unit casing>
Next, an outdoor unit of an air conditioner according to a second exemplary embodiment of the present invention will be described. FIG. 7 is a front view of another example of the outdoor unit of the air conditioner according to the present invention. FIG. 8 is a view showing a metal plate before manufacturing the casing of the outdoor unit of the air conditioner shown in FIG. 7. FIG. 9 is a perspective view of the assembled state of the metal plate shown in FIG. 8 as seen from the back side. The basic configuration of the outdoor unit 1B of the air conditioner of the present embodiment is the same as that of the outdoor unit 1 of the first embodiment described above. Therefore, the same code | symbol is attached | subjected to the part which is common in the outdoor unit 1 of 1st Embodiment of the outdoor unit 1B of this embodiment. Further, description of substantially the same part is omitted.
　空気調和機の室外機１Ｂは、筐体２Ｂを備えている。筐体２Ｂは、底部材２１ｂと、前壁２２ｂと、側壁２３ｂと、側壁２４ｂと、天面板２５と、背面板（不図示）を有している。筐体２Ｂは、底部材２１ｂと前壁２２ｂとが、単一の部材で形成されている。また、筐体２Ｂは、前壁２２ｂと側壁２３ｂおよび側壁２４ｂとが、単一の部材で形成されている。すなわち、一対の側壁２３ｂ、２４ｂが前壁２２と単一の部材である。 The outdoor unit 1B of the air conditioner includes a housing 2B. The housing 2B includes a bottom member 21b, a front wall 22b, a side wall 23b, a side wall 24b, a top plate 25, and a back plate (not shown). In the housing 2B, the bottom member 21b and the front wall 22b are formed of a single member. Moreover, as for the housing | casing 2B, the front wall 22b, the side wall 23b, and the side wall 24b are formed with the single member. That is, the pair of side walls 23b, 24b is a single member with the front wall 22.
　図８に示すように、底部材２１ｂ、前壁２２ｂ、側壁２３ｂおよび側壁２４ｂは、１枚の金属板３Ｂから形成されている。金属板３Ｂは、第１領域３１と、第２領域３２と、第３領域３３と、第４領域３４とを備えている。第１領域３１と、第２領域３２と、第３領域３３と、第４領域３４とは、長方形状である。第１領域３１と第２領域３２とは、隣り合う。また、第２領域３２の第１領域３１との境界線Ｂ１と隣接する２辺のそれぞれは、第３領域３３および第４領域３４が隣り合う。第２領域３２と第３領域３３との境界を境界線Ｂ２とする。また、第２領域３２と第４領域３４との境界を境界線Ｂ３とする。 As shown in FIG. 8, the bottom member 21b, the front wall 22b, the side wall 23b, and the side wall 24b are formed from one metal plate 3B. The metal plate 3 </ b> B includes a first region 31, a second region 32, a third region 33, and a fourth region 34. The first region 31, the second region 32, the third region 33, and the fourth region 34 are rectangular. The first region 31 and the second region 32 are adjacent to each other. In addition, the third region 33 and the fourth region 34 are adjacent to each of two sides adjacent to the boundary line B1 of the second region 32 with the first region 31. A boundary between the second region 32 and the third region 33 is defined as a boundary line B2. The boundary between the second region 32 and the fourth region 34 is defined as a boundary line B3.
　金属板３Ｂを、境界線Ｂ１で折り曲げて、底部材２１および前壁２２が、形成される。また、金属板３Ｂを、境界線Ｂ２で折り曲げて、側壁２３ｂが、形成される。金属板３Ｂを、境界線Ｂ３で折り曲げて、側壁２４ｂが、形成される。つまり、金属板３Ｂにおいて、第３領域３３が、側壁２３ｂとなる。また、金属板３Ｂにおいて、第４領域３４が、側壁２４ｂとなる。なお、弾性変形による戻りを考慮して、側壁２３ｂと前壁２２との角度および側壁２４ｂと前壁２２との角度も、直角よりも小さいことが好ましい。 The metal plate 3B is bent at the boundary line B1, and the bottom member 21 and the front wall 22 are formed. Further, the metal plate 3B is bent at the boundary line B2 to form the side wall 23b. The side wall 24b is formed by bending the metal plate 3B at the boundary line B3. That is, in the metal plate 3B, the third region 33 becomes the side wall 23b. In the metal plate 3B, the fourth region 34 becomes the side wall 24b. In consideration of return due to elastic deformation, the angle between the side wall 23b and the front wall 22 and the angle between the side wall 24b and the front wall 22 are preferably smaller than a right angle.
　金属板３Ｂにおいて、第３領域３３の境界線Ｂ２と反対側の辺には、第３継ぎしろ３３１が形成されている。第４領域３４の境界線Ｂ３と反対側の辺には、第４継ぎしろ３４１が形成されている。第３継ぎしろ３３１は、第３領域３３に対して折り曲げられる。第３継ぎしろ３３１は、側壁２３ｂの後リブ２３２となる。第４継ぎしろ３４１は、第４領域３４に対して折り曲げられる。第４継ぎしろ３４１は、側壁２４ｂの後リブ２４２となる。 In the metal plate 3B, a third joint 331 is formed on the side of the third region 33 opposite to the boundary line B2. A fourth joint 341 is formed on the side of the fourth region 34 opposite to the boundary line B3. The third joint margin 331 is bent with respect to the third region 33. The third joint margin 331 becomes the rear rib 232 of the side wall 23b. The fourth joint margin 341 is bent with respect to the fourth region 34. The fourth joint margin 341 serves as the rear rib 242 of the side wall 24b.
　そして、折り曲げられて形成された側壁２３ｂは、底部材２１の短辺から延びる一対の側部取付部材２１１の一方と固定される。また、折り曲げられて形成された側壁２４ｂは、底部材２１の短辺から延びる一対の側部取付部材２１１の他方と固定される。 The side wall 23b formed by being bent is fixed to one of the pair of side part mounting members 211 extending from the short side of the bottom member 21. Further, the side wall 24 b formed by being bent is fixed to the other of the pair of side attachment members 211 extending from the short side of the bottom member 21.
　このように、筐体２Ｂでは、前壁２２と、側壁２３および側壁２４とが単一の部材として形成されている。前壁２２に、通風部４を介して、ファンモータ８を取り付けたとき、ファンモータ８は、前壁２２に対して偏った位置に設けられている。そのため、ファンモータ８の重量、気流の発生による反作用としての軸力は、前壁２２を内側に傾く方向に作用する。筐体２Ｂのように、側壁２３および側壁２４を、前壁２２と一体に形成することで、前壁２２を内側に倒す力に対抗することができる。また、側壁２３および側壁２４と前壁２２との固定が不要であるため、組み立てに要する手間と時間を削減することができる。 Thus, in the housing 2B, the front wall 22, the side wall 23, and the side wall 24 are formed as a single member. When the fan motor 8 is attached to the front wall 22 via the ventilation portion 4, the fan motor 8 is provided at a position biased with respect to the front wall 22. Therefore, the weight of the fan motor 8 and the axial force as a reaction caused by the generation of the airflow act in a direction in which the front wall 22 is inclined inward. By forming the side wall 23 and the side wall 24 integrally with the front wall 22 as in the case 2B, it is possible to counteract the force to tilt the front wall 22 inward. In addition, since it is not necessary to fix the side wall 23 and the side wall 24 to the front wall 22, it is possible to reduce labor and time required for assembly.
　なお、本実施形態では、側壁２３ｂおよび側壁２４ｂの両方が、側部取付部材２１１に固定されていた。しかしながら、これに限定されるものではなく、少なくとも一方が固定されるものであってもよい。また、固定は、前壁２２と前リブ２３１および前リブ２４１との固定で示した固定構造のいずれかを利用してもよい。ここでは、固定部材Ｆｐとしてねじを用いている。 In this embodiment, both the side wall 23b and the side wall 24b are fixed to the side attachment member 211. However, it is not limited to this, At least one may be fixed. For fixing, any of the fixing structures shown by fixing the front wall 22 to the front rib 231 and the front rib 241 may be used. Here, a screw is used as the fixing member Fp.
　これ以外の特徴については、第１実施形態と同じである。 Other features are the same as in the first embodiment.
＜２．２　第２実施形態の室外機の変形例＞
　続いて、第２実施形態の室外機１の変形例について説明する。図１０は、図７に示す空気調和機の室外機の筐体の製造前の金属板の他の例を示す図である。図１１は、図１０に示す金属板を組み立てた状態を背面側から見た斜視図である。本変形例で示す、金属板３Ｂ２は、金属板３Ｂの第１領域３１に設けられていた第１継ぎしろ３１１に替えて、第３領域３３および第４領域３４に設けられた、第５継ぎしろ３３０と、第６継ぎしろ３４０とが設けられている。これ以外の部分は、同じ構成であるため、同じ部分には同じ符号を付すとともに、同じ部分の詳細な説明は省略する。 <2.2 Modification of Outdoor Unit of Second Embodiment>
Then, the modification of the outdoor unit 1 of 2nd Embodiment is demonstrated. FIG. 10 is a diagram illustrating another example of the metal plate before manufacturing the casing of the outdoor unit of the air conditioner illustrated in FIG. 7. FIG. 11 is a perspective view of the assembled state of the metal plate shown in FIG. 10 as seen from the back side. The metal plate 3B2 shown in this modification is a fifth joint provided in the third region 33 and the fourth region 34 in place of the first joint 311 provided in the first region 31 of the metal plate 3B. A margin 330 and a sixth joint 340 are provided. Since other parts have the same configuration, the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted.
　図１０に示すように、金属板３Ｂ２には、第３領域３３の第１領域３１と近い短辺に設けられた、第５継ぎしろ３３０が設けられている。金属板３Ｂ２には、第４領域３４の第１領域３１と近い短辺に設けられた、第６継ぎしろ３４０が設けられている。第５継ぎしろ３３０は、第３領域３３に対して折り曲げられて、底部取付部材２３３となる。また、第６継ぎしろ３４０は、第４領域３４に対して折り曲げられて、底部取付部材２４３となる。底部取付部材２３３および底部取付部材２４３は、それぞれ、底部材２１ｂの短辺と近接し、底部材２１ｂに固定される。 As shown in FIG. 10, the metal plate 3 </ b> B <b> 2 is provided with a fifth joint 330 provided on the short side of the third region 33 near the first region 31. The metal plate 3 </ b> B <b> 2 is provided with a sixth joint 340 provided on the short side of the fourth region 34 near the first region 31. The fifth joint 330 is bent with respect to the third region 33 to form the bottom attachment member 233. Further, the sixth joint 340 is bent with respect to the fourth region 34 to become a bottom mounting member 243. The bottom mounting member 233 and the bottom mounting member 243 are respectively close to the short side of the bottom member 21b and fixed to the bottom member 21b.
　すなわち、一対の側壁２３ｂ、２４ｂの少なくとも一方に同一部材として形成された底部取付部材２３３、２４３が設けられている。そして、底部取付部材２３３、２４３が底部材２１と固定されている。固定は、前壁２２と前リブ２３１および前リブ２４１との固定で示した固定構造のいずれかを利用してもよい。ここでは、固定部材Ｆｐとしてねじを用いている。 That is, bottom mounting members 233 and 243 formed as the same member are provided on at least one of the pair of side walls 23b and 24b. The bottom mounting members 233 and 243 are fixed to the bottom member 21. For fixing, any one of the fixing structures shown by fixing the front wall 22 to the front rib 231 and the front rib 241 may be used. Here, a screw is used as the fixing member Fp.
　なお、固定部材Ｆｐとしてねじを用いる場合、固定部材Ｆｐは、底部材２１ｂを貫通する場合がある。固定部材Ｆｐが貫通すると、固定部材Ｆｐの先端が、室外機１を設置するときに、邪魔になる場合がある。そこで、図１１に示すように、筐体２Ｂ２では、脚部２０が、底部取付部材２３３および底部取付部材２４３と上下に重なる位置に設けられている。そして、底部取付部材２３３および底部取付部材２４３を貫通した固定部材Ｆｐが、底部材２１および脚部２０を貫通して、固定されている。すなわち、底部取付部材２３３、２４３は、底部材２１及び脚部２０の両方を固定する固定部材Ｆｐを有する。 In addition, when using a screw as the fixing member Fp, the fixing member Fp may penetrate the bottom member 21b. When the fixing member Fp penetrates, the tip of the fixing member Fp may become an obstacle when the outdoor unit 1 is installed. Therefore, as shown in FIG. 11, in the housing 2 </ b> B <b> 2, the leg portion 20 is provided at a position that overlaps with the bottom mounting member 233 and the bottom mounting member 243. And the fixing member Fp which penetrated the bottom part attachment member 233 and the bottom part attachment member 243 penetrates the bottom member 21 and the leg part 20, and is being fixed. In other words, the bottom mounting members 233 and 243 have a fixing member Fp that fixes both the bottom member 21 and the leg 20.
　この構成によると、側壁２３ｂおよび側壁２４ｂを脚部２０に固定している。これにより、側壁２３ｂおよび側壁２４ｂが倒れるのを抑制することができる。 According to this configuration, the side wall 23 b and the side wall 24 b are fixed to the leg portion 20. Thereby, it can suppress that the side wall 23b and the side wall 24b fall down.
＜３．第３実施形態＞
＜３．１　室外機の筐体の構成＞
　次に、本発明の例示的な第３実施形態の空気調和機の室外機について説明する。図１２は、空気調和機の室外機の筐体の製造前の金属板を示す図である。なお、本実施形態の空気調和機の室外機の、基本的な構成は先に説明した第２実施形態の室外機と同じである。 <3. Third Embodiment>
<3.1 Outdoor unit casing configuration>
Next, an outdoor unit of an air conditioner according to an exemplary third embodiment of the present invention will be described. FIG. 12 is a diagram illustrating a metal plate before manufacturing a casing of an outdoor unit of an air conditioner. In addition, the basic structure of the outdoor unit of the air conditioner of this embodiment is the same as the outdoor unit of 2nd Embodiment demonstrated previously.
　本実施形態にかかる、空気調和機の室外機は、前壁２２と通風部４とが単一の部材で形成されている。すなわち、図１２に示す、金属板３Ｃでは、開口部２２１となる貫通孔を形成する部分に、通風部４Ｃを形成する。つまり、貫通孔を形成する予定の部分に、円形部４０ｃを中心として、周囲に複数個の通気孔４３ｃを形成する。このように構成することで、金属板３Ｃのリブ部４１ｃおよびガード部４２ｃが形成される。部品点数を減らすことができる。これにより、空気調和機の室外機１を薄型化できるとともに、重量を削減することができる。 In the outdoor unit of the air conditioner according to this embodiment, the front wall 22 and the ventilation unit 4 are formed of a single member. That is, in the metal plate 3 </ b> C shown in FIG. 12, the ventilation portion 4 </ b> C is formed in the portion where the through hole that becomes the opening 221 is formed. That is, a plurality of vent holes 43c are formed around the circular portion 40c in the portion where the through hole is to be formed. By comprising in this way, the rib part 41c and the guard part 42c of the metal plate 3C are formed. The number of parts can be reduced. Thereby, the outdoor unit 1 of the air conditioner can be reduced in thickness and the weight can be reduced.
　通気孔４３は、金属板３Ｃに貫通孔をプレス加工等で形成される場合がある。金属板にプレス加工で貫通孔を形成する場合、貫通孔の辺縁部分が、尖る場合がある。このように、貫通孔の辺縁部分が尖ると、人の指が接触したときに傷つけやすい。また、人の服等の物品も引っかかりやすい。そのため、通気孔４３ｃの辺縁は、角を丸める加工が施されていることが好ましい。すなわち、通気孔４３ｃの辺縁部は、少なくとも外側の角を丸めておけばよい。そこで、プレス加工の刃の侵入方向を、外面側から内面側とする。プレス加工で貫通孔を形成する場合、刃が侵入する面側の辺縁は、角が尖りにくい。これにより、外側の辺縁部分の角を丸めることが可能である。なお、角を丸めるとは、角を曲面上に加工するものを含むとともに、角に手指が触っても、傷つかない程度の角度にする加工も含む。 The air holes 43 may be formed by pressing a through hole in the metal plate 3C. When forming a through-hole in a metal plate by press work, the edge part of a through-hole may be sharp. Thus, if the edge part of a through-hole is sharp, it will be easy to be damaged when a human finger contacts. Also, articles such as human clothes are easily caught. Therefore, it is preferable that the edge of the vent hole 43c is processed to round the corners. That is, at least the outer corners of the side edge of the vent hole 43c may be rounded. Therefore, the direction in which the pressing blade enters is changed from the outer surface side to the inner surface side. When the through hole is formed by pressing, the edge on the surface side where the blade enters is less likely to have a sharp edge. This makes it possible to round off the corners of the outer edge portion. Note that the rounding of the corner includes not only processing the corner on a curved surface but also processing to make the corner so as not to be damaged even if a finger touches the corner.
＜３．２　第３実施形態の室外機の変形例＞
　次に、本発明の例示的な第３実施形態の空気調和機の室外機の変形例について説明する。図１３は、本発明にかかる空気調和機の室外機の他の例の通風部の断面図である。　　 <3.2 Modification of Outdoor Unit of Third Embodiment>
Next, the modification of the outdoor unit of the air conditioner of 3rd illustrative embodiment of this invention is demonstrated. FIG. 13: is sectional drawing of the ventilation part of the other example of the outdoor unit of the air conditioner concerning this invention.
　図１３に示すような、通風部４Ｃ２を備えていてもよい。通風部４Ｃ２は、通気孔４３ｃが形成されている部分が、円形部４０ｃに比べて外側に突出した形状となっている。このような形状とすることで、通気孔４３ｃが形成されている部分の外面側から、ファンモータ８のインペラ８１までに隙間Ｌ１を設けることができる。このような、隙間Ｌ１は、通気孔４３から手指の先端が筐体の内部に侵入しても、インペラ８１に接触するまでの隙間とすることができる。例えば、人が、通風部４Ｃ２に触れたとしても、インペラ８１に接触しにくく、傷つきにくくなる。 The ventilation part 4C2 as shown in FIG. 13 may be provided. The ventilation portion 4C2 has a shape in which a portion in which the ventilation hole 43c is formed protrudes outward as compared with the circular portion 40c. By setting it as such a shape, the clearance gap L1 can be provided from the outer surface side of the part in which the vent hole 43c is formed to the impeller 81 of the fan motor 8. Such a gap L <b> 1 can be a gap until the impeller 81 contacts the impeller 81 even if the tip of a finger enters the inside of the housing from the vent hole 43. For example, even if a person touches the ventilation part 4C2, it is difficult to contact the impeller 81 and it is difficult to be damaged.
　上述の実施形態において、金属板を折り曲げる場合、材料の弾性変形による戻りを考慮して、底部材２１と前壁２２とがなす角度が、直角よりも小さい角度としている。しかしながら、あまり弾性変形しない材料を用いる場合、弾性変形による戻りを無視することができる。そのため、あまり弾性変形しない材料を用いる場合、底部材２１と前壁２２とがなす角度が直角であってもよい。また、あまり弾性変形しない材料を用いる場合、側壁２３ｂと前壁２２とがなす角度および側壁２４ｂと前壁２２とがなす角度も直角であってもよい。 In the above-described embodiment, when the metal plate is bent, the angle formed by the bottom member 21 and the front wall 22 is smaller than a right angle in consideration of return due to elastic deformation of the material. However, when a material that does not deform elastically is used, the return due to elastic deformation can be ignored. Therefore, when a material that does not elastically deform so much is used, the angle formed by the bottom member 21 and the front wall 22 may be a right angle. In the case of using a material that does not elastically deform so much, the angle formed between the side wall 23b and the front wall 22 and the angle formed between the side wall 24b and the front wall 22 may be perpendicular.
　以上、本発明の実施形態につき説明したが、本発明の範囲はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で種々の変更を加えて実施することができる。また、上記実施形態やその変形例は適宜任意に組み合わせることができる。 The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.
