　図２は、本発明の第１実施形態に係る室外機１の概略分解斜視図である。筐体２は、上述した前面部２ａに加えて、底面部２ｂと、天面部２ｃと、背面部２ｄと、側面部２ｅ及び２ｆと、を有する。天面部２ｃは底面部２ｂより上側に位置する。背面部２ｄには吸気口２１が設けられる。側面部２ｆには吸気口２２が設けられる。前面部２ａ、底面部２ｂ、天面部２ｃ、背面部２ｄ、側面部２ｅ、及び側面部２ｆは、異なる部材として構成され、例えばネジ等の固定具を用いて各部材間の位置関係を固定することで略直方体の筐体２となる。筐体２の内部には、電源部５、圧縮機６、熱交換器７、ファンモータ８、接触部材９等の構成要素が収納される。 FIG. 2 is a schematic exploded perspective view of the outdoor unit 1 according to the first embodiment of the present invention. The housing 2 includes a bottom surface portion 2b, a top surface portion 2c, a back surface portion 2d, and side surface portions 2e and 2f in addition to the above-described front surface portion 2a. The top surface portion 2c is located above the bottom surface portion 2b. An intake port 21 is provided in the back surface portion 2d. An intake port 22 is provided in the side surface portion 2f. The front surface portion 2a, the bottom surface portion 2b, the top surface portion 2c, the back surface portion 2d, the side surface portion 2e, and the side surface portion 2f are configured as different members, and fix the positional relationship between the members using, for example, a fixing tool such as a screw. As a result, the housing 2 has a substantially rectangular parallelepiped shape. The casing 2 houses components such as a power supply unit 5, a compressor 6, a heat exchanger 7, a fan motor 8, and a contact member 9.
　電源部５は、例えば不図示の支持部に支持される。不図示の支持部は底面部２ｂの上面に設置される。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), for example. A support portion (not shown) is installed on the upper surface of the bottom surface portion 2b. 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、底面部２ｂの上面に設置される。圧縮機６は、電源部５の真下に配置される。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、室外機の熱交換機７及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 surface portion 2b. The compressor 6 is disposed directly below the power supply unit 5. 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 the heat exchanger 7 of the outdoor unit and a heat exchanger (not shown) accommodated in the indoor unit.
　熱交換器７は、底面部２ｂの上面に設置される。熱交換器７は、筐体２の内側において背面部２ｄの吸気口２１及び側面部２ｆの吸気口２２に近接して配置される。熱交換器７の形状は例えば平板形状であっても良い。熱交換器７が平板形状である場合には、熱交換器７が背面部２ｄの吸気口２１に近接して配置され、側面部２ｆが吸気口２２を有さないことが望ましい。熱交換器７には、冷媒が流入する。ファンモータ８を駆動すると、外部から吸気口２１及び２２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。 The heat exchanger 7 is installed on the upper surface of the bottom surface portion 2b. The heat exchanger 7 is disposed inside the housing 2 in the vicinity of the air inlet 21 of the back surface portion 2d and the air inlet 22 of the side surface portion 2f. The shape of the heat exchanger 7 may be, for example, a flat plate shape. When the heat exchanger 7 has a flat plate shape, it is desirable that the heat exchanger 7 is disposed close to the air inlet 21 of the back surface portion 2d and the side surface portion 2f does not have the air inlet 22. The refrigerant flows into the heat exchanger 7. When the fan motor 8 is driven, the outside air sucked into the housing 2 through the intake ports 21 and 22 from the outside passes through the heat exchanger 7. The heat exchanger 7 exchanges heat with the outside air sucked into the housing 2.
　ファンモータ８は、筐体２の内側において前面部２ａに取り付けられる。ファンモータ８は、詳細には、筐体２の内側においてカバーパネル４の円板部４０に取り付けられる。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、羽根車と、これを回転させるモータとを組み合わせたものである。 The fan motor 8 is attached to the front surface portion 2 a inside the housing 2. Specifically, the fan motor 8 is attached to the disc portion 40 of the cover panel 4 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 and a motor that rotates the impeller.

＜１－２．接触部材の配置及び構成＞
　続いて、接触部材９の配置及び構成について詳細に説明する。図３は、本発明の第１実施形態に係る室外機１の概略縦断面図である。図３は、切断面がファンモータ８の回転軸線を含み、側面部２ｅ側から側面部２ｆ側を見た縦断面図である。図３では、ファンモータ８の羽根車の図示が省略されている。 <1-2. Arrangement and configuration of contact member>
Next, the arrangement and configuration of the contact member 9 will be described in detail. FIG. 3 is a schematic longitudinal sectional view of the outdoor unit 1 according to the first embodiment of the present invention. FIG. 3 is a longitudinal sectional view of the cut surface including the rotation axis of the fan motor 8 and viewed from the side surface portion 2e side to the side surface portion 2f side. In FIG. 3, the illustration of the impeller of the fan motor 8 is omitted.
　接触部材９は、前面部２ａの熱交換器７に対向する面Ｆ１に接する第１接触部９ａと、熱交換器７の前面部２ａに対向する面Ｆ２に接する第２接触部９ｂと、第１接触部９ａと第２接触部９ｂとを連結する連結部９ｃと、を有する。そして、接触部材９の連結部９ｃは、天面部２ｃに固定される。したがって、接触部材９は、前面部２ａと熱交換器７との接近を規制し、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することを防止する。 The contact member 9 includes a first contact portion 9a in contact with the surface F1 facing the heat exchanger 7 of the front surface portion 2a, a second contact portion 9b in contact with the surface F2 facing the front surface portion 2a of the heat exchanger 7, It has the connection part 9c which connects the 1 contact part 9a and the 2nd contact part 9b. And the connection part 9c of the contact member 9 is fixed to the top | upper surface part 2c. Therefore, the contact member 9 regulates the approach between the front surface portion 2a and the heat exchanger 7 and prevents the fan motor 8 attached to the front surface portion 2a from coming into contact with the heat exchanger 7.
　接触部材９の連結部９ｃは、詳細には、天面部２ｃに溶着されている。接触部材９の上面と天面部２ｃの下面との接触部分において少なくとも一箇所で、接触部材９の連結部９ｃは天面部２ｃに溶着されている。固定構造は溶着以外であっても良い。例えば、ネジ等の固定具を用いて接触部材９の連結部９ｃが天面部２ｃに固定されても良い。 In detail, the connecting portion 9c of the contact member 9 is welded to the top surface portion 2c. The connecting portion 9c of the contact member 9 is welded to the top surface portion 2c at at least one place in the contact portion between the upper surface of the contact member 9 and the lower surface of the top surface portion 2c. The fixing structure may be other than welding. For example, the connecting portion 9c of the contact member 9 may be fixed to the top surface portion 2c using a fixing tool such as a screw.
　天面部２ｃは、第１カバー部Ｃ１と、第２カバー部Ｃ２と、を有する。第１カバー部Ｃ１は、筐体２の外側において前面部２ａの上部を覆う。第２カバー部Ｃ２は、筐体２の外側において背面部２ｄの上部を覆う。 The top surface part 2c has a first cover part C1 and a second cover part C2. The first cover part C <b> 1 covers the upper part of the front face part 2 a outside the housing 2. The second cover portion C2 covers the upper portion of the back surface portion 2d on the outside of the housing 2.
　前面部２ａの上部は、天面部２ｃの第１カバー部Ｃ１と、接触部材９の第１接触部９ａと、によって挟まれる。これにより、前面部２ａの剛性を高めることができる。また、第１カバー部Ｃ１は、例えばネジ等の固定具を用いて前面部２ａに固定されることが望ましい。これにより、前面部２ａの剛性をより一層高めることができる。 The upper portion of the front surface portion 2a is sandwiched between the first cover portion C1 of the top surface portion 2c and the first contact portion 9a of the contact member 9. Thereby, the rigidity of the front surface portion 2a can be increased. Further, it is desirable that the first cover part C1 is fixed to the front face part 2a using a fixing tool such as a screw. Thereby, the rigidity of the front surface part 2a can be further increased.
　熱交換器７の上部及び背面部２ｄの上部は、接触部材９の第２接触部９ｂと、天面部２ｃの第２カバー部Ｃ２と、によって挟まれる。これにより、熱交換器７及び背面部２ｄの剛性を高めることができる。第２カバー部Ｃ２は、例えばネジ等の固定具を用いて背面部２ｄに固定されることが望ましい。これにより、熱交換器７及び背面部２ｄの剛性をより一層高めることができる。 The upper part of the heat exchanger 7 and the upper part of the back surface part 2d are sandwiched between the second contact part 9b of the contact member 9 and the second cover part C2 of the top surface part 2c. Thereby, the rigidity of the heat exchanger 7 and the back surface part 2d can be improved. The second cover portion C2 is preferably fixed to the back surface portion 2d using a fixing tool such as a screw. Thereby, the rigidity of heat exchanger 7 and back part 2d can be raised further.
　材料を特に限定する趣旨ではないが、接触部材９は例えば板金部品で構成される。接触部材９の第１接触部９ａ及び第２接触部９ｂは、弾性部を有する。接触部材９の第１接触部９ａ及び第２接触部９ｂは、詳細には、板バネ構造の弾性部を有する。 Although the material is not particularly limited, the contact member 9 is made of, for example, a sheet metal part. The first contact portion 9a and the second contact portion 9b of the contact member 9 have elastic portions. Specifically, the first contact portion 9a and the second contact portion 9b of the contact member 9 have elastic portions having a leaf spring structure.
　なお、接触部材９の第１接触部９ａ及び第２接触部９ｂが板バネ構造以外の弾性部を有しても良い。板バネ構造以外の弾性部としては、例えばつるまきバネ、弾性ゴム等を挙げることができる。ただし、接触部材９の第１接触部９ａ及び第２接触部９ｂが板バネ構造の弾性部を有する場合、接触部材９を例えば図４に示す側面形状の板金部品すなわち単一部材で構成することができる。これにより、複数の部材で構成されるよりも接触部材９の低コスト化を図ることができる。 In addition, the 1st contact part 9a and the 2nd contact part 9b of the contact member 9 may have elastic parts other than a leaf | plate spring structure. Examples of the elastic portion other than the leaf spring structure include a helical spring and an elastic rubber. However, when the first contact portion 9a and the second contact portion 9b of the contact member 9 have an elastic portion having a leaf spring structure, the contact member 9 is constituted by a sheet metal part having a side shape shown in FIG. 4, for example, a single member. Can do. Thereby, the cost reduction of the contact member 9 can be achieved rather than comprising a plurality of members.
　図４に示す側面形状では第１接触部９ａと連結部９ｃとのなす角θ１が鈍角である。そして、図３に示す組み立て完了後の状態では図４に示す接触部材９が拘束されていない状態よりも第１接触部９ａと連結部９ｃとのなす角θ１が小さくなる。したがって、前面部２ａは、第１接触部９ａが有する弾性部の付勢力により第１カバー部Ｃ１に押し付けられる。これにより、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することをより一層防止することができる。 4, the angle θ1 formed by the first contact portion 9a and the connecting portion 9c is an obtuse angle. In the state after the completion of assembly shown in FIG. 3, the angle θ1 formed by the first contact portion 9a and the connecting portion 9c is smaller than in the state where the contact member 9 shown in FIG. 4 is not restrained. Therefore, the front surface portion 2a is pressed against the first cover portion C1 by the urging force of the elastic portion of the first contact portion 9a. Thereby, it can further prevent that the fan motor 8 attached to the front part 2a contacts the heat exchanger 7.
　図４に示す側面形状では第２接触部９ｂと連結部９ｃとのなす角θ２が鈍角である。そして、図３に示す組み立て完了後の状態では図４に示す接触部材９が拘束されていない状態よりも第２接触部９ｂと連結部９ｃとのなす角θ２が小さくなる。したがって、熱交換器７は、第２接触部９ｂが有する弾性部の付勢力により背面部２ｄに押し付けられる。これにより、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することをより一層防止することができる。 4, the angle θ2 formed by the second contact portion 9b and the connecting portion 9c is an obtuse angle. Then, in the state after completion of the assembly shown in FIG. 3, the angle θ2 formed by the second contact portion 9b and the connecting portion 9c is smaller than in the state where the contact member 9 shown in FIG. 4 is not restrained. Accordingly, the heat exchanger 7 is pressed against the back surface portion 2d by the urging force of the elastic portion of the second contact portion 9b. Thereby, it can further prevent that the fan motor 8 attached to the front part 2a contacts the heat exchanger 7.
　図３に示すように、接触部材９の第１接触部９ａの下端が天面部２ｃの第１カバー部Ｃ１の下端よりも下側に位置することが望ましい。このような位置関係にすれば、接触部材９の第１接触部９ａが板バネ構造の弾性部を有する場合であっても、前面部２ａの上部が天面部２ｃの第１カバー部Ｃ１と接触部材９の第１接触部９ａとの間に容易に挿入される。 As shown in FIG. 3, it is desirable that the lower end of the first contact portion 9a of the contact member 9 is located below the lower end of the first cover portion C1 of the top surface portion 2c. With such a positional relationship, even if the first contact portion 9a of the contact member 9 has an elastic portion having a leaf spring structure, the upper portion of the front surface portion 2a is in contact with the first cover portion C1 of the top surface portion 2c. It is easily inserted between the member 9 and the first contact portion 9a.
　図３に示すように、接触部材９の第２接触部９ｂの下端が天面部２ｃの第２カバー部Ｃ２の下端よりも下側に位置することが望ましい。このような位置関係にすれば、接触部材９の第２接触部９ｂが板バネ構造の弾性部を有する場合であっても、熱交換器７の上部及び背面部２ｄの上部が接触部材９の第２接触部９ｂと天面部２ｃの第２カバー部Ｃ２との間に容易に挿入される。 As shown in FIG. 3, it is desirable that the lower end of the second contact portion 9b of the contact member 9 is located below the lower end of the second cover portion C2 of the top surface portion 2c. With such a positional relationship, even when the second contact portion 9b of the contact member 9 has an elastic portion having a leaf spring structure, the upper portion of the heat exchanger 7 and the upper portion of the back surface portion 2d are connected to the contact member 9. It is easily inserted between the second contact portion 9b and the second cover portion C2 of the top surface portion 2c.
　図５は、ファンモータ８と接触部材９とを底面部２ｂに垂直な方向から見た図である。図５は、ファンモータ８と接触部材９とを底面部２ｂ側から見た図である。図５では、ファンモータ８の羽根車の図示が省略されている。 FIG. 5 is a view of the fan motor 8 and the contact member 9 as seen from a direction perpendicular to the bottom surface portion 2b. FIG. 5 is a view of the fan motor 8 and the contact member 9 as seen from the bottom surface portion 2b side. In FIG. 5, the illustration of the impeller of the fan motor 8 is omitted.
　接触部材９は、底面部２ｂに垂直な方向においてファンモータ８に対向する。これにより、接触部材９が底面部２ｂに垂直な方向においてファンモータ８に対向しない場合と比較して、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することをより一層防止することができる。 The contact member 9 faces the fan motor 8 in a direction perpendicular to the bottom surface portion 2b. Thereby, compared with the case where the contact member 9 does not oppose the fan motor 8 in the direction perpendicular | vertical to the bottom face part 2b, it is much more that the fan motor 8 attached to the front-surface part 2a contacts the heat exchanger 7. Can be prevented.
　接触部材９の幅Ｗ１は、ファンモータ８のモータの幅Ｗ２より大きい。これにより、接触部材９の幅Ｗ１がファンモータ８のモータの幅Ｗ２以下である場合と比較して、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することをより一層防止することができる。なお、接触部材９の幅Ｗ１をファンモータ８全体の幅より大きくすると、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することを更により一層防止することができる。 The width W1 of the contact member 9 is larger than the motor width W2 of the fan motor 8. Thereby, compared with the case where the width W1 of the contact member 9 is equal to or smaller than the motor width W2 of the fan motor 8, the fan motor 8 attached to the front surface portion 2a is further in contact with the heat exchanger 7. Can be prevented. If the width W1 of the contact member 9 is larger than the entire width of the fan motor 8, it is possible to further prevent the fan motor 8 attached to the front surface portion 2a from coming into contact with the heat exchanger 7.
＜１－３．第１実施形態の室外機１の変形例＞
　続いて、第１実施形態の室外機１の変形例について説明する。図６は、本発明の第１実施形態に係る室外機１の変形例の概略縦断面図である。図６は、切断面がファンモータ８の回転軸線を含み、側面部２ｅ側から側面部２ｆ側を見た縦断面図である。図６では、ファンモータ８の羽根車の図示が省略されている。 <1-3. Modification of Outdoor Unit 1 of First Embodiment>
Then, the modification of the outdoor unit 1 of 1st Embodiment is demonstrated. FIG. 6 is a schematic longitudinal sectional view of a modification of the outdoor unit 1 according to the first embodiment of the present invention. FIG. 6 is a longitudinal sectional view of the cut surface including the rotation axis of the fan motor 8 and viewed from the side surface portion 2e side to the side surface portion 2f side. In FIG. 6, the illustration of the impeller of the fan motor 8 is omitted.
　第１実施形態の室外機１の変形例と第１実施形態の室外機１とは、熱交換器７と背面部２ｄとの位置関係が異なる。第１実施形態の室外機１では、熱交換器７が背面部２ｄに接する。一方、第１実施形態の室外機１の変形例では、熱交換器７が背面部２ｄに接せずに背面部２ｄの近くに配置される。 The positional relationship between the heat exchanger 7 and the back surface portion 2d is different between the modified example of the outdoor unit 1 of the first embodiment and the outdoor unit 1 of the first embodiment. In the outdoor unit 1 of the first embodiment, the heat exchanger 7 is in contact with the back surface portion 2d. On the other hand, in the modification of the outdoor unit 1 of the first embodiment, the heat exchanger 7 is disposed near the back surface portion 2d without contacting the back surface portion 2d.
　この構成によれば、前面部２ａの上部、熱交換器７の上部、及び背面部２ｄの上部に天面部２ｃを被せる作業が容易になり、作業効率が向上する。 According to this configuration, it is easy to cover the top surface portion 2c on the upper portion of the front surface portion 2a, the upper portion of the heat exchanger 7, and the upper portion of the back surface portion 2d, and the work efficiency is improved.
＜２．第２実施形態＞
＜２－１．室外機のカバー部の周辺の構成＞
　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、本発明の第２実施形態に係る空気調和機の室外機１の概略縦断面図である。図７は、切断面がファンモータ８の回転軸線を含み、側面部２ｅ側から側面部２ｆ側を見た縦断面図である。図７では、ファンモータ８の羽根車の図示が省略されている。図８は、本発明の第２実施形態に係る接触部材９と前面パネル３の展開図である。なお、本実施形態の基本的な構成は先に説明した第１実施形態と同じであるので、第１実施形態と共通する構成要素には前と同じ符号または同じ名称を付してその説明を省略する場合がある。 <2. Second Embodiment>
<2-1. Configuration around the cover of the outdoor unit>
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 schematic longitudinal sectional view of the outdoor unit 1 of the air conditioner according to the second embodiment of the present invention. FIG. 7 is a longitudinal sectional view of the cut surface including the rotation axis of the fan motor 8 and viewed from the side surface portion 2e side to the side surface portion 2f side. In FIG. 7, the illustration of the impeller of the fan motor 8 is omitted. FIG. 8 is a development view of the contact member 9 and the front panel 3 according to the second embodiment of the present invention. Since the basic configuration of the present embodiment is the same as that of the first embodiment described above, the same reference numerals or the same names as those used before are assigned to the same constituent elements as those of the first embodiment, and the description thereof is omitted. May be omitted.
　接触部材９と前面部２ａの少なくとも一部とは、単一部材として構成される。詳細には、接触部材９と前面パネル３とは、単一部材として構成される。材料を特に限定する趣旨ではないが、接触部材９と前面パネル３とによって構成される単一部材は例えば板金部品で構成される。 The contact member 9 and at least a part of the front surface portion 2a are configured as a single member. Specifically, the contact member 9 and the front panel 3 are configured as a single member. Although the material is not particularly limited, the single member constituted by the contact member 9 and the front panel 3 is constituted by, for example, a sheet metal part.
　接触部材９は、熱交換器７の前面部２ａに対向する面Ｆ２に接する接触部９ｄと、前面パネル３と接触部９ｄとを連結する連結部９ｅと、を有する。接触部材９は、熱交換器７の上端に接することにより接触部９ｄの下方への移動を規制する規制部９ｆをさらに有する。したがって、接触部材９は、前面部２ａと熱交換器７との接近を規制し、前面部２ａに取り付けられているファンモータ８が熱交換器７に接触することを防止する。 The contact member 9 has a contact portion 9d that contacts the surface F2 facing the front surface portion 2a of the heat exchanger 7, and a connecting portion 9e that connects the front panel 3 and the contact portion 9d. The contact member 9 further includes a restricting portion 9f that restricts the downward movement of the contact portion 9d by contacting the upper end of the heat exchanger 7. Therefore, the contact member 9 regulates the approach between the front surface portion 2a and the heat exchanger 7 and prevents the fan motor 8 attached to the front surface portion 2a from coming into contact with the heat exchanger 7.
　接触部材９は、末端部９ｇをさらに備える。末端部９ｇは、熱交換器７と背面部２ｄとによって挟まれる。末端部９ｇは、熱交換器７と背面部２ｄとの間でスペーサとして機能する。末端部９ｇを設けない構成としてもよい。末端部９ｇを設けなくても、接触部材９は、前面部２ａと熱交換器７との接近を規制する。 The contact member 9 further includes a terminal portion 9g. The end portion 9g is sandwiched between the heat exchanger 7 and the back surface portion 2d. The end portion 9g functions as a spacer between the heat exchanger 7 and the back surface portion 2d. It is good also as a structure which does not provide the terminal part 9g. Even if the terminal portion 9g is not provided, the contact member 9 regulates the approach between the front surface portion 2a and the heat exchanger 7.
　この構造により、接触部材９と天面部２ｃとがネジや溶接などで固定していなくとも、接触部材９はその位置で保持される。つまり、ネジが落下したり、溶接箇所が劣化したとしても、接触部材９は前面部２ａ及び熱交換器７で支えられるため、接触部材９自身が落下することを防ぐことができる。 This structure allows the contact member 9 to be held in that position even if the contact member 9 and the top surface portion 2c are not fixed by screws or welding. That is, even if the screw is dropped or the welded portion is deteriorated, the contact member 9 is supported by the front surface portion 2a and the heat exchanger 7, so that the contact member 9 itself can be prevented from falling.
＜２－２．第２実施形態の室外機１の第１変形例＞
　続いて、第２実施形態の室外機１の第１変形例について説明する。図９は、本発明の第２実施形態の第１変形例に係る接触部材９と前面パネル３の展開図である。 <2-2. First Modification of Outdoor Unit 1 of Second Embodiment>
Then, the 1st modification of the outdoor unit 1 of 2nd Embodiment is demonstrated. FIG. 9 is a development view of the contact member 9 and the front panel 3 according to a first modification of the second embodiment of the present invention.
　第２実施形態の室外機１の第１変形例と第２実施形態の室外機１とは、接触部材９の形状が異なる。第２実施形態の室外機１では、図８に示す展開図において接触部９ｄの外縁三方が規制部９ｆに囲まれる。一方、第２実施形態の室外機１の第１変形例では、図９に示す展開図において一対の接触部９ｄの間に規制部９ｆが形成される。 The first modification of the outdoor unit 1 of the second embodiment and the outdoor unit 1 of the second embodiment differ in the shape of the contact member 9. In the outdoor unit 1 of the second embodiment, the three outer edges of the contact portion 9d are surrounded by the restriction portion 9f in the developed view shown in FIG. On the other hand, in the 1st modification of the outdoor unit 1 of 2nd Embodiment, the control part 9f is formed between a pair of contact parts 9d in the expanded view shown in FIG.
　第２実施形態の室外機１の第１変形例と第２実施形態の室外機１とにおいて、接触部９ｄの機能及び規制部９ｆの機能に差異はない。したがって、第２実施形態の室外機１の第１変形例は第２実施形態の室外機１と同様の効果を奏する。 In the first modified example of the outdoor unit 1 of the second embodiment and the outdoor unit 1 of the second embodiment, there is no difference in the function of the contact portion 9d and the function of the regulating portion 9f. Therefore, the 1st modification of the outdoor unit 1 of 2nd Embodiment has an effect similar to the outdoor unit 1 of 2nd Embodiment.
＜２－３．第２実施形態の室外機１の第２変形例＞
　続いて、第２実施形態の室外機１の第２変形例について説明する。図１０は、本発明の第２実施形態の第２変形例に係る接触部材９と前面パネル３の展開図である。 <2-3. Second Modification of Outdoor Unit 1 of Second Embodiment>
Then, the 2nd modification of the outdoor unit 1 of 2nd Embodiment is demonstrated. FIG. 10 is a development view of the contact member 9 and the front panel 3 according to a second modification of the second embodiment of the present invention.
　第２実施形態の室外機１の第２変形例と第２実施形態の室外機１及び第２実施形態の室外機１の第１変形例とは、接触部材９の形状が異なる。第２実施形態の室外機１及び第２実施形態の室外機１の第１変形例では、接触部材９が対称形状である。一方、第２実施形態の室外機１の第２変形例では、接触部材９が非対称形状である。 The shape of the contact member 9 differs between the second modification of the outdoor unit 1 of the second embodiment, the outdoor unit 1 of the second embodiment, and the first modification of the outdoor unit 1 of the second embodiment. In the first modification of the outdoor unit 1 of the second embodiment and the outdoor unit 1 of the second embodiment, the contact member 9 is symmetrical. On the other hand, in the 2nd modification of the outdoor unit 1 of 2nd Embodiment, the contact member 9 is asymmetrical shape.
　第２実施形態の室外機１の第２変形例と第２実施形態の室外機１及び第２実施形態の室外機１の第１変形例とにおいて、接触部９ｄの機能及び規制部９ｆの機能に差異はない。したがって、第２実施形態の室外機１の第２変形例は第２実施形態の室外機１及び第２実施形態の室外機１の第１変形例と同様の効果を奏する。 In the second modified example of the outdoor unit 1 of the second embodiment, the outdoor unit 1 of the second embodiment, and the first modified example of the outdoor unit 1 of the second embodiment, the function of the contact portion 9d and the function of the regulating unit 9f. There is no difference. Therefore, the 2nd modification of the outdoor unit 1 of 2nd Embodiment has an effect similar to the 1st modification of the outdoor unit 1 of 2nd Embodiment and the outdoor unit 1 of 2nd Embodiment.
＜２－４．第２実施形態の室外機１の第３変形例＞
　続いて、第２実施形態の室外機１の第３変形例について説明する。図１１は、本発明の第２実施形態の第３変形例に係る空気調和機の室外機１の概略縦断面図である。図１１は、切断面がファンモータ８の回転軸線を含み、側面部２ｅ側から側面部２ｆ側を見た縦断面図である。図１１では、ファンモータ８の羽根車の図示が省略されている。 <2-4. Third Modification of Outdoor Unit 1 of Second Embodiment>
Then, the 3rd modification of the outdoor unit 1 of 2nd Embodiment is demonstrated. FIG. 11 is a schematic longitudinal sectional view of an outdoor unit 1 for an air conditioner according to a third modification of the second embodiment of the present invention. FIG. 11 is a longitudinal sectional view of the cut surface including the rotation axis of the fan motor 8 and viewed from the side surface portion 2e side to the side surface portion 2f side. In FIG. 11, the illustration of the impeller of the fan motor 8 is omitted.
　第２実施形態の室外機１の第３変形例と第２実施形態の室外機１とは、熱交換器７と接触部材９との位置関係が異なる。第２実施形態の室外機１の第３変形例では、熱交換器７の上端が接触部材９に接しない。したがって、第２実施形態の室外機１において接触部材９の規制部９ｆであった部分は、第２実施形態の室外機１の第３変形例では接触部９ｄの下方への移動を規制しない。 The positional relationship between the heat exchanger 7 and the contact member 9 is different between the third modification of the outdoor unit 1 of the second embodiment and the outdoor unit 1 of the second embodiment. In the third modification of the outdoor unit 1 of the second embodiment, the upper end of the heat exchanger 7 does not contact the contact member 9. Therefore, the part which was the control part 9f of the contact member 9 in the outdoor unit 1 of 2nd Embodiment does not control the downward movement of the contact part 9d in the 3rd modification of the outdoor unit 1 of 2nd Embodiment.
　このため、第２実施形態の室外機１の第３変形例では、接触部材９の末端部９ｇは例えばネジ等の固定具を用いて背面部２ｄと天面部２ｃの第２カバー部Ｃ２とに固定される。この固定構造が接触部９ｄの下方への移動を規制する。したがって、第２実施形態の室外機１の第３変形例は第２実施形態の室外機１と同様の効果を奏する。 For this reason, in the 3rd modification of the outdoor unit 1 of 2nd Embodiment, the terminal part 9g of the contact member 9 is used for the back part 2d and the 2nd cover part C2 of the top | upper surface part 2c using fixtures, such as a screw, for example. Fixed. This fixing structure restricts the downward movement of the contact portion 9d. Therefore, the 3rd modification of the outdoor unit 1 of 2nd Embodiment has an effect similar to the outdoor unit 1 of 2nd Embodiment.
＜２－５．第２実施形態の室外機１の第４変形例＞
　続いて、第２実施形態の室外機１の第４変形例について説明する。図１２は、本発明の第２実施形態の第４変形例に係る空気調和機の室外機１の概略縦断面図である。図１２は、切断面がファンモータ８の回転軸線を含み、側面部２ｅ側から側面部２ｆ側を見た縦断面図である。図１２では、ファンモータ８の羽根車の図示が省略されている。 <2-5. Fourth Modified Example of Outdoor Unit 1 of Second Embodiment>
Then, the 4th modification of the outdoor unit 1 of 2nd Embodiment is demonstrated. FIG. 12 is a schematic longitudinal sectional view of an outdoor unit 1 for an air conditioner according to a fourth modification of the second embodiment of the present invention. FIG. 12 is a longitudinal sectional view of the cut surface including the rotation axis of the fan motor 8 and viewed from the side surface portion 2e side to the side surface portion 2f side. In FIG. 12, the illustration of the impeller of the fan motor 8 is omitted.
　第２実施形態の室外機１の第４変形例と第２実施形態の室外機１とは、接触部材９の形状が異なる。第２実施形態の室外機１の第４変形例では、接触部材９は規制部９ｆ及び末端部９ｇを有さない。 The fourth modification of the outdoor unit 1 of the second embodiment and the outdoor unit 1 of the second embodiment differ in the shape of the contact member 9. In the 4th modification of the outdoor unit 1 of 2nd Embodiment, the contact member 9 does not have the control part 9f and the terminal part 9g.
　このため、第２実施形態の室外機１の第４変形例では、接触部材９の連結部９ｃは例えばネジ等の固定具を用いて天面部２ｃに固定される。この固定構造が接触部９ｄの下方への移動を規制する。したがって、第２実施形態の室外機１の第４変形例は第２実施形態の室外機１と同様の効果を奏する。 For this reason, in the 4th modification of the outdoor unit 1 of 2nd Embodiment, the connection part 9c of the contact member 9 is fixed to the top | upper surface part 2c using fixtures, such as a screw, for example. This fixing structure restricts the downward movement of the contact portion 9d. Therefore, the 4th modification of the outdoor unit 1 of 2nd Embodiment has an effect similar to the outdoor unit 1 of 2nd Embodiment.
＜３．その他＞
　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。 <3. Other>
Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. Moreover, the said embodiment and its modification can be combined arbitrarily arbitrarily.
　例えば、第１実施形態及び第２実施形態のように前面パネル３と底面部２ｂとを別々の部材で構成するのではなく、図１３に示す展開図のように前面パネル３と底面部２ｂとは単一部材として構成しても良い。さらに、図１４に示す展開図のように前面パネル３と底面部２ｂとによって構成される端一部材に側面部２ｅと側面部２ｆとを含めてもよい。図１４に示す展開図では、底面部２ｂと側面部２ｅ及び２ｆとの接続に用いる重複部２ｇは底面部２ｂ側に設けられる。一方、図１５に示す展開図のように、重複部２ｇは側面部２ｅ及び２ｆ側に設けられても良い。 For example, the front panel 3 and the bottom surface portion 2b are not composed of separate members as in the first embodiment and the second embodiment, but the front panel 3 and the bottom surface portion 2b as shown in a development view shown in FIG. May be configured as a single member. Furthermore, as shown in the development view shown in FIG. 14, the end face member constituted by the front panel 3 and the bottom face part 2b may include the side face part 2e and the side face part 2f. In the developed view shown in FIG. 14, the overlapping portion 2g used for connection between the bottom surface portion 2b and the side surface portions 2e and 2f is provided on the bottom surface portion 2b side. On the other hand, as shown in the developed view of FIG. 15, the overlapping portion 2g may be provided on the side surface portions 2e and 2f.
　例えば、第１実施形態及び第２実施形態のように筐体２の前面部２ａを前面パネル３とカバーパネル４とによって構成するのではなく、図１６に示す概略斜視図のように、筐体２の前面部２ａを単一部材として構成しても良い。さらに、図１３～図１５のいずれかの変更例と組み合わせても良い。 For example, the front portion 2a of the housing 2 is not constituted by the front panel 3 and the cover panel 4 as in the first and second embodiments, but as shown in the schematic perspective view shown in FIG. The two front portions 2a may be configured as a single member. Further, it may be combined with any of the modified examples in FIGS.
　例えばカバーパネル４が板金部品である場合または筐体２の前面部２ａを単一部材として構成する場合に、筐体２の前面部２ａに設けられる排気口は、金属板に貫通孔をプレス加工等で形成されることがある。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、排気口の辺縁は、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、排気口の辺縁部は、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。 For example, when the cover panel 4 is a sheet metal part or the front part 2a of the casing 2 is configured as a single member, the exhaust port provided in the front part 2a of the casing 2 presses a through hole in the metal plate. Or the like. 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 exhaust port is processed to round the corners. That is, at least the outer corners of the edge of the exhaust port 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.
　例えば筐体２の前面部２ａに設けられる排気口が形成されている部分が、ファンモータ８が取り付けられる円形部に比べて外側に突出した形状であっても良い。このような形状とすることで、排気口が形成されている部分の外面側からファンモータ８の羽根車までの距離を長くすることができる。したがって、もし排気口から手指の先端が筐体２の内部に侵入してもファンモータ８の羽根車に接触することを防止することができる。 For example, the portion where the exhaust port provided in the front surface portion 2a of the housing 2 is formed may have a shape protruding outward as compared to the circular portion to which the fan motor 8 is attached. By setting it as such a shape, the distance from the outer surface side of the part in which the exhaust port is formed to the impeller of the fan motor 8 can be lengthened. Therefore, even if the tip of a finger enters the inside of the housing 2 from the exhaust port, it can be prevented from contacting the impeller of the fan motor 8.
　例えば、筐体２の前面部２ａにリブを設けても良い。詳細には、図１７に示す正面図のように、前面パネル３の下端から上端に向かう方向に沿って延びるリブ３ｂが前面パネル３に設けられる。このような構造により、前面パネル３の下端から上端に向かう方向における前面パネル３の剛性を高めることができる。また、図１７に示す構造の代わりに、図１８に示す正面図のように、前面パネル３の下端から上端に向かう方向に垂直な方向に沿って延びるリブ３ｂが前面パネル３に設けられても良い。このような構造により、前面パネル３の下端から上端に向かう方向に垂直な方向における前面パネル３の剛性を高めることができる。リブ３ｂの個数及びリブ３ｂ各々の形状は限定されない。例えば、図１７に示す形状とは異なりリブ３ｂが筐体２の前面部２ａの下端から上端まで延びる形状であってもよい。また、例えば、図１８に示す形状とは異なりリブ３ｂが筐体２の前面部２ａの左端から右端まで延びる形状であってもよい。前面パネル３の振動及び筐体２の共振を効果的に抑制できるように、構造解析シミュレーション又は実物を用いた実験によってリブ３ｂの個数及びリブ３ｂ各々の形状を設計すれば良い。各々のリブ３ｂは、例えば、筐体２の内側から外側に向かって突出する前面パネル３の窪み、筐体２の外側から内側に向かって突出する前面パネル３の窪み、筐体２の内側において前面パネル３に貼り付けられる補強部材のいずれかによって構成する。図１７に示す構造と図１８に示す構造を組み合わせて実施しても良い。さらに、リブ３ｂを設ける構造は、図１３～図１５のいずれかの変更例と図１６の変更例の少なくとも一方と組み合わせても良い。 For example, you may provide a rib in the front part 2a of the housing | casing 2. FIG. Specifically, as shown in the front view of FIG. 17, the front panel 3 is provided with ribs 3 b extending along the direction from the lower end to the upper end of the front panel 3. With such a structure, the rigidity of the front panel 3 in the direction from the lower end to the upper end of the front panel 3 can be increased. Further, instead of the structure shown in FIG. 17, ribs 3 b extending along a direction perpendicular to the direction from the lower end to the upper end of the front panel 3 may be provided on the front panel 3 as shown in the front view of FIG. 18. good. With such a structure, the rigidity of the front panel 3 in the direction perpendicular to the direction from the lower end to the upper end of the front panel 3 can be increased. The number of ribs 3b and the shape of each rib 3b are not limited. For example, unlike the shape shown in FIG. 17, the rib 3 b may have a shape extending from the lower end to the upper end of the front surface portion 2 a of the housing 2. Further, for example, unlike the shape shown in FIG. 18, the rib 3 b may have a shape extending from the left end to the right end of the front surface portion 2 a of the housing 2. What is necessary is just to design the number of the ribs 3b and the shape of each rib 3b by structural analysis simulation or the experiment using the actual thing so that the vibration of the front panel 3 and the resonance of the housing | casing 2 can be suppressed effectively. Each of the ribs 3b includes, for example, a recess in the front panel 3 that protrudes from the inside to the outside of the housing 2, a recess in the front panel 3 that protrudes from the outside to the inside of the housing 2, and the inside of the housing 2 It is comprised by either of the reinforcement members affixed on the front panel 3. FIG. You may implement combining the structure shown in FIG. 17, and the structure shown in FIG. Furthermore, the structure in which the rib 3b is provided may be combined with at least one of the modified examples of any of FIGS. 13 to 15 and the modified example of FIG.
　なお、図１３～図１８は第１実施形態に対する変更例を示しているが、同様の変更は第２実施形態に対しても適用することができる。 Although FIG. 13 to FIG. 18 show examples of changes to the first embodiment, similar changes can be applied to the second embodiment.
