以下、添付図面を参照しつつ本発明の一実施形態を説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

図１は空気調和機の構成を概略的に示す概念図である。空気調和機１１はいわゆる室内機１２を備える。室内機１２は例えば屋内に設置される。室内機１２には室内熱交換器１３が組み込まれる。室内熱交換器１３には送風機１４が向き合わせられる。例えば冷房時には室内熱交換器１３は蒸発器として機能する。冷媒は室内熱交換器１３内を通過することで空気から熱エネルギーを吸収して蒸発する。空気は熱エネルギーを奪われ冷却される。冷却された空気は送風機１４の働きで送り出される。暖房時には室内熱交換器１３は凝縮器として機能する。冷媒は室内熱交換器１３内を通過することで空気に熱エネルギーを放出し凝縮する。空気は熱エネルギーを吸収し暖められる。暖められた空気は送風機１４の働きで送り出される。 FIG. 1 is a conceptual diagram schematically showing the configuration of an air conditioner. The air conditioner 11 includes a so-called indoor unit 12. The indoor unit 12 is installed indoors, for example. An indoor heat exchanger 13 is incorporated in the indoor unit 12. A blower 14 is opposed to the indoor heat exchanger 13. For example, during cooling, the indoor heat exchanger 13 functions as an evaporator. As the refrigerant passes through the indoor heat exchanger 13, it absorbs heat energy from the air and evaporates. Air is deprived of heat energy and cooled. The cooled air is sent out by the function of the blower 14. During heating, the indoor heat exchanger 13 functions as a condenser. By passing through the indoor heat exchanger 13, the refrigerant releases heat energy into the air and condenses. Air absorbs heat energy and is warmed. The warmed air is sent out by the function of the blower 14.

空気調和機１１はいわゆる室外機１５を備える。室外機１５は例えば屋外に設置される。室外機１５には室外熱交換器１６が組み込まれる。室外熱交換器１６には送風ファン１７が向き合わせられる。例えば冷房時には室外熱交換器１６は凝縮器として機能する。冷媒は室外熱交換器１６内を通過することで空気に熱エネルギーを放出し凝縮する。空気は熱エネルギーを吸収し暖められる。暖められた空気は送風ファン１７の働きで送り出される。暖房時には室外熱交換器１６は蒸発器として機能する。冷媒は室外熱交換器１６内を通過することで空気から熱エネルギーを吸収して蒸発する。空気は熱エネルギーを奪われ冷却される。冷却された空気は送風ファン１７の働きで送り出される。 The air conditioner 11 includes a so-called outdoor unit 15. The outdoor unit 15 is installed outdoors, for example. An outdoor heat exchanger 16 is incorporated in the outdoor unit 15. A blower fan 17 faces the outdoor heat exchanger 16. For example, the outdoor heat exchanger 16 functions as a condenser during cooling. The refrigerant passes through the outdoor heat exchanger 16 to release heat energy into the air and condense. Air absorbs heat energy and is warmed. The warmed air is sent out by the function of the blower fan 17. The outdoor heat exchanger 16 functions as an evaporator during heating. As the refrigerant passes through the outdoor heat exchanger 16, it absorbs heat energy from the air and evaporates. Air is deprived of heat energy and cooled. The cooled air is sent out by the function of the blower fan 17.

室外機１５にはアキュムレーター１９、圧縮機２１、四方弁２２および膨張手段２３がさらに組み込まれる。四方弁２２は第１口２２ａおよび第２口２２ｂで第１循環経路２４に接続される。第１循環経路２４には室内熱交換器１３、膨張手段２３および室外熱交換器１６が順番に挿入される。膨張手段２３には例えば双方向性のキャピラリが用いられればよい。同様に、四方弁２２は第３口２２ｃおよび第４口２２ｄで第２循環経路２５に接続される。第２循環経路２５にはアキュムレーター１９および圧縮機２１が順番に挿入される。第１循環経路２４および第２循環経路２５は例えば銅管などの冷媒配管で形成される。アキュムレーター１９には冷媒が蓄えられる。アキュムレーター１９の流出口には圧縮機２１の吸込口２１ａが接続される。圧縮機２１は冷媒を圧縮する。圧縮機２１は四方弁２２に向かって高圧の冷媒を送り出す。 The outdoor unit 15 further includes an accumulator 19, a compressor 21, a four-way valve 22 and an expansion means 23. The four-way valve 22 is connected to the first circulation path 24 through the first port 22a and the second port 22b. The indoor heat exchanger 13, the expansion means 23, and the outdoor heat exchanger 16 are inserted into the first circulation path 24 in order. For example, a bidirectional capillary may be used as the expansion means 23. Similarly, the four-way valve 22 is connected to the second circulation path 25 through the third port 22c and the fourth port 22d. The accumulator 19 and the compressor 21 are inserted into the second circulation path 25 in order. The first circulation path 24 and the second circulation path 25 are formed of a refrigerant pipe such as a copper pipe, for example. A refrigerant is stored in the accumulator 19. A suction port 21 a of the compressor 21 is connected to the outlet of the accumulator 19. The compressor 21 compresses the refrigerant. The compressor 21 sends high-pressure refrigerant toward the four-way valve 22.

冷房時には四方弁２２は第１位置で圧縮機２１の吐出口２１ｂに室外熱交換器１６を接続する。同時に、四方弁２２は室内熱交換器１３にアキュムレーター１９を接続する。室外熱交換器１６には高圧の冷媒が送り込まれる。室外熱交換器１６は凝縮器として作用する。膨張手段２３で冷媒は減圧される。低圧の冷媒は室内熱交換器１３に送り込まれる。こうして室内熱交換器１３は蒸発器として作用する。室内熱交換器１３から冷媒はアキュムレーター１９に流れ込む。 During cooling, the four-way valve 22 connects the outdoor heat exchanger 16 to the discharge port 21b of the compressor 21 at the first position. At the same time, the four-way valve 22 connects the accumulator 19 to the indoor heat exchanger 13. A high-pressure refrigerant is fed into the outdoor heat exchanger 16. The outdoor heat exchanger 16 acts as a condenser. The refrigerant is decompressed by the expansion means 23. The low-pressure refrigerant is sent into the indoor heat exchanger 13. Thus, the indoor heat exchanger 13 functions as an evaporator. The refrigerant flows from the indoor heat exchanger 13 into the accumulator 19.

一方で、暖房時には四方弁２２は第２位置で圧縮機２１の吐き出し口２１ｂに室内熱交換器１３を接続する。同時に、四方弁２２は室外熱交換器１６にアキュムレーター１９を接続する。室内熱交換器１３には高圧の冷媒が送り込まれる。室内熱交換器１３は凝縮器として作用する。膨張手段２３で冷媒は減圧される。低圧の冷媒は室外熱交換器１６に送り込まれる。室外熱交換器１６は蒸発器として作用する。室外熱交換器１６から冷媒はアキュムレーター１９に流れ込む。こうして圧縮機２１、室外熱交換器１６、膨張手段２３、室内熱交換器１３およびアキュムレーター１９で冷凍サイクルは確立される。 On the other hand, the four-way valve 22 connects the indoor heat exchanger 13 to the discharge port 21b of the compressor 21 at the second position during heating. At the same time, the four-way valve 22 connects the accumulator 19 to the outdoor heat exchanger 16. A high-pressure refrigerant is fed into the indoor heat exchanger 13. The indoor heat exchanger 13 acts as a condenser. The refrigerant is decompressed by the expansion means 23. The low-pressure refrigerant is sent to the outdoor heat exchanger 16. The outdoor heat exchanger 16 acts as an evaporator. The refrigerant flows from the outdoor heat exchanger 16 into the accumulator 19. In this way, a refrigeration cycle is established by the compressor 21, the outdoor heat exchanger 16, the expansion means 23, the indoor heat exchanger 13, and the accumulator 19.

図２に示されるように、室外機１６は筐体２６を備える。筐体２６は箱形に構成される。筐体２６は収容空間を囲む。筐体２６のフロントパネル２７には前面通気口２８が形成される。フロントパネル２７は収容空間の前側を塞ぐ。筐体２６は前後１対ずつの脚２９で例えば地面や床面に支持される。図２には前側の脚２９のみが図示される。 As shown in FIG. 2, the outdoor unit 16 includes a housing 26. The casing 26 is configured in a box shape. The casing 26 surrounds the accommodation space. A front vent 28 is formed in the front panel 27 of the housing 26. The front panel 27 closes the front side of the accommodation space. The housing 26 is supported by, for example, the ground surface or the floor surface by a pair of legs 29 at the front and back. Only the front leg 29 is shown in FIG.

図３は室外機１５の正面図を示す。フロントパネル２７は取り外されている。筐体２６内の収容空間には仕切り壁３１が配置される。仕切り壁３１は筐体２６の底板３２から鉛直方向に直立する。仕切り壁３１は熱交換器室３３と機械室３４とに収容空間を区分けする。熱交換器室３３にはパネル状の室外熱交換器１６が配置される。室外熱交換器１６は筐体２６のリアパネルを兼ねる。室外熱交換器１６は１対のパネル板に挟み込まれる配管を備える。配管内に冷媒は流通する。 FIG. 3 is a front view of the outdoor unit 15. The front panel 27 is removed. A partition wall 31 is disposed in the accommodation space in the housing 26. The partition wall 31 stands upright from the bottom plate 32 of the housing 26 in the vertical direction. The partition wall 31 divides the accommodation space into a heat exchanger chamber 33 and a machine chamber 34. A panel-shaped outdoor heat exchanger 16 is disposed in the heat exchanger chamber 33. The outdoor heat exchanger 16 also serves as the rear panel of the housing 26. The outdoor heat exchanger 16 includes a pipe sandwiched between a pair of panel plates. The refrigerant flows through the pipe.

熱交換器室３３には送風ファン１７が配置される。送風ファン１７のブレードは室外熱交換器１６に直交する方向に延びる回転軸回りで回転する。送風ファン１７は軸方向に気流を生成する。室外熱交換器１６すなわちリアパネルには背面通気口３５が形成される。熱交換器室３３内では送風ファン１７の働きで背面通気口３５から前述の前面通気口２８に向かって空気が流通する。 A blower fan 17 is disposed in the heat exchanger chamber 33. The blades of the blower fan 17 rotate around a rotation axis extending in a direction orthogonal to the outdoor heat exchanger 16. The blower fan 17 generates an air flow in the axial direction. A rear vent 35 is formed in the outdoor heat exchanger 16, that is, the rear panel. In the heat exchanger chamber 33, air flows from the rear vent 35 toward the aforementioned front vent 28 by the function of the blower fan 17.

機械室３４には圧縮機２１やアキュムレーター１９、膨張手段２３、四方弁２２、いわゆる電装品箱３６その他の機械部品や電装部品が収容される。図３には機械部品や電装部品の一部が示される。電装品箱３６は仕切り壁３１に固定される。電装品箱３６は内部空間すなわち収容空間を区画する。 The machine chamber 34 accommodates the compressor 21, the accumulator 19, the expansion means 23, the four-way valve 22, a so-called electrical component box 36, and other mechanical components and electrical components. FIG. 3 shows some mechanical parts and electrical parts. The electrical component box 36 is fixed to the partition wall 31. The electrical component box 36 defines an internal space, that is, an accommodation space.

電装品箱３６は壁板３７を備える。壁板３７は収容空間の側面を塞ぐ。壁板３７と仕切り壁３１とは共通の垂直面に沿って広がる。壁板３７の外面にはヒートシンク３８が固定される。ヒートシンク３８の詳細は後述される。ヒートシンク３８は熱交換器室３３に臨む。したがって、ヒートシンク３８は熱交換器室３３内で流通する空気に曝される。ヒートシンク３８の放熱は促進される。 The electrical component box 36 includes a wall plate 37. The wall plate 37 closes the side surface of the accommodation space. The wall plate 37 and the partition wall 31 extend along a common vertical plane. A heat sink 38 is fixed to the outer surface of the wall plate 37. Details of the heat sink 38 will be described later. The heat sink 38 faces the heat exchanger chamber 33. Therefore, the heat sink 38 is exposed to the air circulating in the heat exchanger chamber 33. Heat dissipation of the heat sink 38 is promoted.

電装品箱３６は天板３９を備える。天板３９は壁板３７の上端に接続される。天板３９は水平面に沿って広がる。天板３９は収容空間の天井面を塞ぐ。電装品箱３６は蓋体４１をさらに備える。蓋体４１は鉛直面に沿って広がる。蓋体４１は収容空間の前面を覆う。蓋体４１は壁板３７および天板３９に連結される。連結にあたって例えばねじが用いられる。 The electrical component box 36 includes a top plate 39. The top plate 39 is connected to the upper end of the wall plate 37. The top plate 39 extends along a horizontal plane. The top plate 39 closes the ceiling surface of the accommodation space. The electrical component box 36 further includes a lid 41. The lid body 41 extends along a vertical plane. The lid 41 covers the front surface of the accommodation space. The lid 41 is connected to the wall plate 37 and the top plate 39. For example, a screw is used for connection.

図４は電装品箱３６の拡大図を示す。図４では蓋体４１は取り外されている。電装品箱３６は扉体４２を備える。扉体４２は垂直軸回りで回転自在に壁板３７に連結される。連結の詳細は後述される。扉体４２の表面には第１制御基板４３が取り付けられる。第１制御基板４３は例えば前述の圧縮機２１や前述の送風ファン１７の制御および前述の室内機１２との通信に利用される。 FIG. 4 shows an enlarged view of the electrical component box 36. In FIG. 4, the lid 41 is removed. The electrical component box 36 includes a door body 42. The door body 42 is connected to the wall plate 37 so as to be rotatable about a vertical axis. Details of the connection will be described later. A first control board 43 is attached to the surface of the door body 42. The first control board 43 is used, for example, for control of the compressor 21 and the blower fan 17 described above and for communication with the indoor unit 12 described above.

図５に示されるように、壁板３７は部分的に収容空間を囲む。壁板３７の内面には第２制御基板４４が支持される。したがって、第２制御基板４４は収容空間に収容される。図６に示されるように、第２制御基板４４は前述のヒートシンク３８に接続される。接続にあたって壁板３７には窓孔４５が形成される。窓孔４５内にはパワーモジュールやパワートランジスタといった高発熱部品４６すなわち熱源が配置される。高発熱部品４６は第２制御基板４４の裏面に実装される。高発熱部品４６はヒートシンク３８に連結される。連結にあたって例えば高発熱部品４６とヒートシンク３８との間には熱伝導ペーストが挟み込まれればよい。こうして高発熱部品４６の熱エネルギーはヒートシンク３８に伝達される。ヒートシンク３８からの放熱に応じて高発熱部品４６の温度上昇は抑制されることができる。 As shown in FIG. 5, the wall plate 37 partially surrounds the accommodation space. A second control board 44 is supported on the inner surface of the wall plate 37. Therefore, the second control board 44 is accommodated in the accommodation space. As shown in FIG. 6, the second control board 44 is connected to the heat sink 38 described above. A window hole 45 is formed in the wall plate 37 for connection. In the window hole 45, a highly heat generating component 46 such as a power module or a power transistor, that is, a heat source is arranged. The high heat generating component 46 is mounted on the back surface of the second control board 44. The high heat generating component 46 is connected to the heat sink 38. For connection, for example, a heat conductive paste may be sandwiched between the high heat generating component 46 and the heat sink 38. Thus, the heat energy of the high heat generating component 46 is transmitted to the heat sink 38. The temperature rise of the high heat-generating component 46 can be suppressed according to the heat radiation from the heat sink 38.

図７は壁板３７および扉体４２の分解斜視図を示す。扉体４２は支持板５１を備える。支持板５１は第１基準平面５２内で広がる。支持体５１には前述の第１制御基板４３が支持される。第１制御基板４３の裏面は支持板５１の表面に受け止められる。 FIG. 7 is an exploded perspective view of the wall plate 37 and the door body 42.

第１狭壁体６３には第２基準平面６２から最も離れた位置に縁６３ａが形成される。縁６３ａは、第２基準平面６２に平行に、かつ、鉛直方向に延びる。縁６３ａには第２狭壁板６６が接続される。第２狭壁板６６は第２仮想直立平面６７内で広がる。第２仮想直立平面６７は１鉛直線６８で第１仮想直立平面６４に直交する。この１鉛直線６８は第１仮想直立平面６４および第２仮想直立平面６７の稜線を形成する。第１狭壁板６３および第２狭壁板６６は稜線の内側で相互に接続される。第２狭壁板６６は第１狭壁板６３から連続する。ここでは、第２狭壁板６６、第１狭壁板６３および壁板本体６１は１枚の板材から成形される。成形にあたって例えば板金の折り曲げ加工が用いられる。 An edge 63 a is formed on the first narrow wall body 63 at a position farthest from the second reference plane 62. The edge 63a extends in parallel to the second reference plane 62 and in the vertical direction. A second narrow wall plate 66 is connected to the edge 63a. The second narrow wall plate 66 extends in the second virtual upright plane 67. The second virtual upright plane 67 is perpendicular to the first virtual upright plane 64 at one vertical line 68. The one vertical line 68 forms a ridge line of the first virtual upright plane 64 and the second virtual upright plane 67. The first narrow wall plate 63 and the second narrow wall plate 66 are connected to each other inside the ridge line. The second narrow wall plate 66 continues from the first narrow wall plate 63. Here, the 2nd narrow wall board 66, the 1st narrow wall board 63, and the wall board main body 61 are shape | molded from one board | plate material. For forming, for example, a sheet metal bending process is used.

第１狭壁板６３および第２狭壁板６６には上下１対のヒンジ用開口７１が形成される。個々のヒンジ用開口７１は稜線に沿って鉛直方向に延びる。ヒンジ用開口７１の上端同士の間隔Ｇｂはヒンジ片５８の上端同士の間隔Ｇｈに等しく設定される。同時に、個々のヒンジ用開口７１では、その鉛直方向長さＬｂ１、Ｌｂ２は対応のヒンジ片５８の鉛直方向長さＬｈ１、Ｌｈ２よりも大きく設定される。 A pair of upper and lower hinge openings 71 are formed in the first narrow wall plate 63 and the second narrow wall plate 66. Each hinge opening 71 extends in the vertical direction along the ridgeline. The gap Gb between the upper ends of the hinge openings 71 is set equal to the gap Gh between the upper ends of the hinge pieces 58. At the same time, the vertical lengths Lb1 and Lb2 of the individual hinge openings 71 are set larger than the vertical lengths Lh1 and Lh2 of the corresponding hinge pieces 58.

第２狭壁板６６には規制片７２が形成される。規制片７２は第２狭壁板６６の表面から直立する。規制片７２の表面は、前述の第１仮想直立平面６４に平行に広がる第３仮想直立平面７３内で広がる。第３仮想直立平面７３は第１仮想直立平面６４から第１距離Ｄ１で離れる。第１距離Ｄ１は第１狭壁板６３の板厚および補助板片５６の板厚の総計よりも大きく設定される。加えて、上側のヒンジ用開口７１の下端と規制片７２の下端との間には第２距離Ｄ２が設定される。ここでは、規制片７２は板材から形成される。規制片７２および第２狭壁板６６は同一の板材から成形されればよい。成形にあたって板金の折り曲げ加工が用いられればよい。 A restriction piece 72 is formed on the second narrow wall plate 66. The restricting piece 72 stands upright from the surface of the second narrow wall plate 66. The surface of the restricting piece 72 extends in the third virtual upright plane 73 that extends parallel to the first virtual upright plane 64 described above. The third virtual upright plane 73 is separated from the first virtual upright plane 64 by a first distance D1. The first distance D1 is set to be larger than the total thickness of the first narrow wall plate 63 and the auxiliary plate piece 56. In addition, a second distance D <b> 2 is set between the lower end of the upper hinge opening 71 and the lower end of the restriction piece 72. Here, the regulation piece 72 is formed from a plate material. The restricting piece 72 and the second narrow wall plate 66 may be formed from the same plate material. A sheet metal bending process may be used for forming.

図８に示されるように、補助板片５６には突出片７４が形成される。突出片７４は補助板片５６の表面から直立する。補助板片５６の縁５６ａよりも引っ込んだ位置で補助板片５６から第１基準平面５２に向かって延びる。上側のスリット５９の上端と突出片７４の上端との間には第３距離Ｄ３が設定される。ここでは、突出片７４は板材から形成される。突出片７４および補助板片５６は同一の板材から成形されればよい。成形にあたって板金の折り曲げ加工が用いられればよい。 As shown in FIG. 8, a protruding piece 74 is formed on the auxiliary plate piece 56. The protruding piece 74 stands upright from the surface of the auxiliary plate piece 56. The auxiliary plate piece 56 extends from the auxiliary plate piece 56 toward the first reference plane 52 at a position retracted from the edge 56a. A third distance D3 is set between the upper end of the upper slit 59 and the upper end of the protruding piece 74. Here, the protruding piece 74 is formed of a plate material. The protruding piece 74 and the auxiliary plate piece 56 may be formed from the same plate material. A sheet metal bending process may be used for forming.

図９に示されるように、個々のヒンジ片５８は対応のヒンジ用開口７１に受け入れられる。ここで、スリット５９の幅は第１狭壁板６３および第２狭壁板６６の板厚よりも大きく設定される。したがって、ヒンジ用開口７１の下端で第１狭壁板６３および第２狭壁板６６はスリット５９内に進入する。スリット５９の上端はヒンジ用開口７１の下端で第１狭壁板６３および第２狭壁板６６の縁に支持される。こうして扉体４２は壁板３７に鉛直軸回りに回転自在に連結される。 As shown in FIG. 9, each hinge piece 58 is received in a corresponding hinge opening 71. Here, the width of the slit 59 is set larger than the plate thickness of the first narrow wall plate 63 and the second narrow wall plate 66. Accordingly, the first narrow wall plate 63 and the second narrow wall plate 66 enter the slit 59 at the lower end of the hinge opening 71. The upper end of the slit 59 is supported by the edges of the first narrow wall plate 63 and the second narrow wall plate 66 at the lower end of the hinge opening 71. Thus, the door body 42 is connected to the wall plate 37 so as to be rotatable about the vertical axis.

図１０に示されるように、扉体４２では支持板５１の裏面に第３制御基板７５が支持される。第３制御基板７５の裏面は支持板５１の裏面に受け止められる。第３制御基板７５は扉体４２の背後で収容空間に収容される。 As shown in FIG. 10, the third control board 75 is supported on the back surface of the support plate 51 in the door body 42. The back surface of the third control board 75 is received by the back surface of the support plate 51. The third control board 75 is accommodated in the accommodating space behind the door body 42.

扉体４２には回転規制部材７６が取り付けられる。回転規制部材７６は取り付け片７７を備える。取り付け片７７は扉体４２の天板５３に固定される。固定にあたって例えばスポット溶接が用いられる。 A rotation regulating member 76 is attached to the door body 42. The rotation restricting member 76 includes an attachment piece 77. The attachment piece 77 is fixed to the top plate 53 of the door body 42. For example, spot welding is used for fixing.

回転規制部材７６は弾性体の板片７８を備える。板片７８は取り付け板７７に接続される。板片７８は側板５４に重ね合わせられる第１部分板片７９を備える。第１部分板片７９は、取り付け板７７から最も遠ざかる位置に縁を７９ａ形成する。縁７９ａは水平方向に延びる。縁７９ａには第２部分板片８１が接続される。第２部分板片８１は側板５４の表面から直立する。第２部分板片８１は、側板５４から最も遠ざかる位置に縁８１ａを形成する。縁８１ａは、側板５４の表面に平行に、かつ、水平方向に延びる。縁８１ａには第３部分板片８２が接続される。第３部分板片８２は第１部分板片７９に平行に広がる。第３部分板片８２は第２部分板片８１の先端から鉛直方向上方に向かって広がる。 The rotation restricting member 76 includes an elastic plate piece 78. The plate piece 78 is connected to the mounting plate 77. The plate piece 78 includes a first partial plate piece 79 superimposed on the side plate 54. The first partial plate piece 79 forms an edge 79 a at a position farthest from the attachment plate 77. The edge 79a extends in the horizontal direction. A second partial plate piece 81 is connected to the edge 79a. The second partial plate piece 81 stands upright from the surface of the side plate 54. The second partial plate piece 81 forms an edge 81 a at a position farthest from the side plate 54. The edge 81a extends in parallel to the surface of the side plate 54 and in the horizontal direction. A third partial plate piece 82 is connected to the edge 81a. The third partial plate piece 82 extends in parallel to the first partial plate piece 79. The third partial plate piece 82 extends from the tip of the second partial plate piece 81 upward in the vertical direction.

第３部分板片８２には開口８３が形成される。開口８３の上端で第３部分板片８２の縁は水平方向に延びる。縁には湾曲片８４が接続される。湾曲片８４は第３部分板片８２から側板５４の表面を含む仮想平面に向かって延びる。開口８３の働きで第３部分板片８２の剛性は弱められる。その結果、第３部分板片８２には弾性力が付与される。 An opening 83 is formed in the third partial plate piece 82. At the upper end of the opening 83, the edge of the third partial plate piece 82 extends in the horizontal direction. A curved piece 84 is connected to the edge. The curved piece 84 extends from the third partial plate piece 82 toward a virtual plane including the surface of the side plate 54. The rigidity of the third partial plate piece 82 is weakened by the action of the opening 83. As a result, an elastic force is applied to the third partial plate piece 82.

湾曲片８４は第１部分片８５および第２部分片８６を備える。第１部分片８５は第３部分板片８２に接続される。第１部分片８５は板片７８の第３部分板片８２から遠ざかるにつれて徐々に第２部分板片８１に向かって下降する。第１部分片８５は、第３部分板片８２から最も遠ざかる位置に縁を形成する。縁は天板５３の表面に平行に水平方向に延びる。縁には第２部分片８６が接続される。第２部分片８６は第３部分板片８２から遠ざかるにつれて徐々に第２部分板片８１から遠ざかる方向に上昇する。ここでは、湾曲片８４、板片７８および取り付け片７７は１枚の板材から成形される。成形にあたって例えば板金の折り曲げ加工が用いられる。 The curved piece 84 includes a first piece 85 and a second piece 86. The first partial piece 85 is connected to the third partial plate piece 82. The first partial piece 85 gradually descends toward the second partial plate piece 81 as it moves away from the third partial plate piece 82 of the plate piece 78. The first partial piece 85 forms an edge at a position farthest from the third partial plate piece 82. The edge extends in the horizontal direction parallel to the surface of the top plate 53. A second piece 86 is connected to the edge. The second partial piece 86 gradually rises away from the second partial plate piece 81 as it moves away from the third partial plate piece 82. Here, the curved piece 84, the plate piece 78, and the attachment piece 77 are formed from a single plate material. For forming, for example, a sheet metal bending process is used.

図１１は図９の矢視図を示す。図１１に示されるように、前述のヒンジ片５８が個々に前述のヒンジ用開口７１に受け入れられると、扉体４２の側板５４は壁板３７の壁板本体６１に向き合わせられる。側板５４は壁板本体６１に平行に広がる。このとき、前述の第２仮想直立平面６７と第２基準平面６２との間には所定の間隔が設定される。この間隔の働きで側板５４と壁板本体６１との間には十分な間隔が確保される。その結果、扉体４２上の回転規制部材７６と壁板本体６１上の第２制御基板４４との接触は回避されることができる。 FIG. 11 shows an arrow view of FIG. As shown in FIG. 11, when the aforementioned hinge pieces 58 are individually received in the aforementioned hinge openings 71, the side plates 54 of the door body 42 face the wall plate main body 61 of the wall plate 37. The side plate 54 extends parallel to the wall plate main body 61. At this time, a predetermined interval is set between the second virtual upright plane 67 and the second reference plane 62 described above. A sufficient distance is secured between the side plate 54 and the wall plate main body 61 by the action of the distance. As a result, contact between the rotation restricting member 76 on the door body 42 and the second control board 44 on the wall plate main body 61 can be avoided.

図１２に示されるように、天板３９には補助垂直板８９が接続される。補助垂直板８９は第１仮想直立平面６４に平行に広がる。補助垂直板８９は天板３９の前端から鉛直方向に下方に延びる。補助垂直板８９には長孔９１が形成される。長孔９１は水平方向に直線的に延びる１対の縁で仕切られる。長孔９１の大きさは、前述の湾曲片８４の出入りを許容する程度に設定される。 As shown in FIG. 12, an auxiliary vertical plate 89 is connected to the top plate 39. The auxiliary vertical plate 89 extends parallel to the first virtual upright plane 64. The auxiliary vertical plate 89 extends downward from the front end of the top plate 39 in the vertical direction. A slot 91 is formed in the auxiliary vertical plate 89. The long hole 91 is partitioned by a pair of edges extending linearly in the horizontal direction. The size of the long hole 91 is set to an extent that allows the curved piece 84 to enter and exit.

図１３に示されるように、この室外機１５では扉体４２は開き位置と閉じ位置との間で回転することができる。扉体４２が開き位置に位置すると、壁板３７で囲まれる収容空間の開口は開放される。例えばメンテナンスの作業者は機械室３４内の機械部品や電装部品に簡単にアクセスすることができる。その結果、例えば圧縮機２１や第２制御基板４４に対して簡単にメンテナンス作業を実施することができる。同時に、扉体４２の裏側が表に向く。したがって、作業者は第３制御基板７５に対して簡単にメンテナンス作業を実施することができる。しかも、メンテナンス作業にあたって扉体は室外機１５の仕切り壁３１上に保持される。メンテナンス作業中に扉体４２の置き場に困ることはない。 As shown in FIG. 13, in this outdoor unit 15, the door body 42 can rotate between an open position and a closed position. When the door body 42 is located at the open position, the opening of the accommodation space surrounded by the wall plate 37 is opened. For example, a maintenance worker can easily access mechanical parts and electrical parts in the machine room 34. As a result, for example, maintenance work can be easily performed on the compressor 21 and the second control board 44. At the same time, the back side of the door body 42 faces front. Therefore, the operator can easily perform maintenance work on the third control board 75. Moreover, the door body is held on the partition wall 31 of the outdoor unit 15 during the maintenance work. There is no problem with the storage location of the door 42 during the maintenance work.

扉体４２が閉じ位置に位置すると、壁板３７で囲まれる収容空間の開口は閉鎖される。第３制御基板７５は収容空間に収容される。このとき、図４に示されるように、扉体４２の表側が表に向く。したがって、作業者は第１制御基板４３に対して簡単にメンテナンス作業を実施することができる。こうした第１制御基板４３のメンテナンス作業にあたって電装品箱３６から前述の蓋体４１が取り外されればよい。 When the door body 42 is located at the closed position, the opening of the accommodation space surrounded by the wall plate 37 is closed. The third control board 75 is accommodated in the accommodation space. At this time, as shown in FIG. 4, the front side of the door 42 faces the front. Therefore, the operator can easily perform maintenance work on the first control board 43. The above-described lid 41 may be removed from the electrical component box 36 for such maintenance work of the first control board 43.

前述のように、この室外機１５では鉛直軸回りで９０度の回転角にわたって扉体４２は回転する。こういった回転の実現にあたって、例えば図１４に示されるように、個々のヒンジ用開口７１は第１狭壁板６３の外縁９２および第２狭壁板６６の外縁９３で挟まれる。第１狭壁板６３の外縁９２は１鉛直線上で延びる。同様に、第２狭壁板６６の外縁９３は１鉛直線上で延びる。第２狭壁板６６の外縁９３は、第１狭壁板６３の内面を含む第１仮想平面９４から対応のヒンジ片５８の厚みよりも大きい距離で離れる。その結果、扉体４２が閉じ位置に位置する際に、ヒンジ片５８は第１狭壁体６３に平行な姿勢を維持することができる。このとき、前述のように、上側のヒンジ用開口７１の下端と規制片７２の下端との間には第２距離Ｄ２が設定される一方で、上側のスリット５９の上端と突出片７４の上端との間には第３距離Ｄ３が設定される。第３距離Ｄ３と第２距離Ｄ２の差分（Ｄ３−Ｄ２）は上側のスリット５９の鉛直方向長さよりも小さく設定される。すなわち、ヒンジ片５８がヒンジ用開口７１に受け入れられた際に突出片７４は上側のスリット５９の鉛直方向長さよりも短い間隔で鉛直方向に規制片７２に向き合わせられる。したがって、たとえ閉じ位置の扉体４２に鉛直方向上方に持ち上げ力が作用しても、扉体４２の鉛直方向変位は制限される。その結果、個々のヒンジ片５８は対応のヒンジ用開口７１から離脱することはできない。こうして閉じ位置の扉体４２は確実に壁板３７との連結状態を維持する。 As described above, in the outdoor unit 15, the door body 42 rotates over a rotation angle of 90 degrees around the vertical axis. In realizing such rotation, for example, as shown in FIG. 14, each hinge opening 71 is sandwiched between the outer edge 92 of the first narrow wall plate 63 and the outer edge 93 of the second narrow wall plate 66. The outer edge 92 of the first narrow wall plate 63 extends on one vertical line. Similarly, the outer edge 93 of the second narrow wall plate 66 extends on one vertical line. The outer edge 93 of the second narrow wall plate 66 is separated from the first virtual plane 94 including the inner surface of the first narrow wall plate 63 by a distance larger than the thickness of the corresponding hinge piece 58. As a result, when the door body 42 is located at the closed position, the hinge piece 58 can maintain a posture parallel to the first narrow wall body 63. At this time, as described above, the second distance D2 is set between the lower end of the upper hinge opening 71 and the lower end of the restricting piece 72, while the upper end of the upper slit 59 and the upper end of the protruding piece 74 are set. A third distance D3 is set between. The difference (D3−D2) between the third distance D3 and the second distance D2 is set to be smaller than the vertical length of the upper slit 59. That is, when the hinge piece 58 is received in the hinge opening 71, the protruding piece 74 is opposed to the restriction piece 72 in the vertical direction at an interval shorter than the vertical length of the upper slit 59. Therefore, even if a lifting force acts on the door body 42 in the closed position in the vertical direction, the vertical displacement of the door body 42 is limited. As a result, the individual hinge pieces 58 cannot be detached from the corresponding hinge openings 71. Thus, the door body 42 in the closed position reliably maintains the connection state with the wall plate 37.

図１５に示されるように、第１狭壁板６３の外縁９２は、第２狭壁板６６の内面を含む第２仮想平面９５から対応のヒンジ片５８の厚みよりも大きい距離で離れる。その結果、扉体４２が開き位置に位置する際に、ヒンジ片５８は第２狭壁体６６に平行な姿勢を確立することができる。こういったヒンジ用開口７１の広がりに応じて扉体４２の回転は実現される。このとき、突出片７４は、規制片７２に鉛直方向に向き合う位置から待避する。したがって、開き位置の扉体４２に鉛直方向上方に持ち上げ力が作用すると、扉体４２は鉛直方向に変位する。その結果、個々のヒンジ片５８は対応のヒンジ用開口７１から離脱することができる。こうして開き位置の扉体４２は壁板３７から分離されることができる。 As shown in FIG. 15, the outer edge 92 of the first narrow wall plate 63 is separated from the second virtual plane 95 including the inner surface of the second narrow wall plate 66 by a distance larger than the thickness of the corresponding hinge piece 58. As a result, when the door body 42 is located at the open position, the hinge piece 58 can establish a posture parallel to the second narrow wall body 66. The rotation of the door body 42 is realized according to the spread of the hinge opening 71. At this time, the protruding piece 74 is retracted from a position facing the regulating piece 72 in the vertical direction. Therefore, when a lifting force acts on the door 42 in the open position in the vertical direction, the door 42 is displaced in the vertical direction. As a result, the individual hinge pieces 58 can be detached from the corresponding hinge openings 71. Thus, the door 42 in the open position can be separated from the wall plate 37.

図１６に示されるように、扉体４２が閉じ位置から開き位置に回転する際に、扉体４２が開き位置に近づくと、鉛直軸回りの回転に応じて回転規制部材７６の第３部分板片８２は補助垂直板８９に接近していく。すると、湾曲片８４の第２部分片８６は長孔９１の下端で補助垂直板８９の縁に接触する。ここで、スリット５９の上端から第１部分片８５の縁すなわち下端まで第４距離Ｄ４が設定される。スリット５９の上端から第２部分片８６の縁すなわち上端まで第５距離Ｄ５が設定される。同時に、ヒンジ用開口７１の下端から長孔９１の下端まで第６距離Ｄ６が設定される。第５距離Ｄ５は第６距離Ｄ６よりも大きく設定される一方で、第４距離Ｄ４は第６距離Ｄ６よりも小さく設定される。したがって、湾曲片８４は第２部分片８６の傾斜面で長孔９１の下端に押し付けられる。扉体４２がさらに開き位置に向かって回転すると、湾曲片８４は長孔９１の下端に乗り上げる。扉体４２の回転力は第２部分片８６の傾斜面の働きで湾曲片８４に垂直方向駆動力を作用させる。湾曲片８４の垂直方向駆動力は第３部分板片８２の弾性変形を引き起こす。その結果、湾曲片８４は上方に変位する。湾曲片８４は長孔９１内に受け入れられる。 As shown in FIG. 16, when the door body 42 rotates from the closed position to the open position, when the door body 42 approaches the open position, the third partial plate of the rotation restricting member 76 according to the rotation around the vertical axis. The piece 82 approaches the auxiliary vertical plate 89. Then, the second partial piece 86 of the curved piece 84 comes into contact with the edge of the auxiliary vertical plate 89 at the lower end of the long hole 91. Here, a fourth distance D4 is set from the upper end of the slit 59 to the edge of the first partial piece 85, that is, the lower end. A fifth distance D5 is set from the upper end of the slit 59 to the edge of the second partial piece 86, that is, the upper end. At the same time, a sixth distance D6 is set from the lower end of the hinge opening 71 to the lower end of the long hole 91. The fifth distance D5 is set larger than the sixth distance D6, while the fourth distance D4 is set smaller than the sixth distance D6. Therefore, the curved piece 84 is pressed against the lower end of the long hole 91 by the inclined surface of the second partial piece 86. When the door body 42 further rotates toward the open position, the curved piece 84 rides on the lower end of the long hole 91. The rotational force of the door body 42 causes a vertical driving force to act on the curved piece 84 by the action of the inclined surface of the second partial piece 86. The vertical driving force of the curved piece 84 causes elastic deformation of the third partial plate piece 82. As a result, the curved piece 84 is displaced upward. The curved piece 84 is received in the long hole 91.

扉体４２が開き位置に到達すると、図１７に示されるように、湾曲片８４は第３部分板片８２の弾性力に応じて長孔９１の下端で補助垂直板８９の縁に離脱可能に係り合う。扉体４２が開き位置に到達すると、図１８に示されるように、回転規制部材７６の第３部分板片８２は補助垂直板８９に重ね合わせられる。扉体４２の回転は開き位置で制限される。扉体４２の回転は開き位置を超えて継続することはできない。過度の扉体４２の開きは防止される。同時に、湾曲片８４では第２部分片８６は長孔９１の下端を乗り越える。第１部分片８５が長孔９１の下端に受け止められる。前述と反対向きに扉体４２の回転は規制される。こうして扉体４２は開き位置で保持されることができる。作業者は扉体４２に邪魔されることなくメンテナンス作業を実施し続けることができる。回転規制部材７６と補助垂直板８９とは協働で回転規制機構を構成する。 When the door body 42 reaches the open position, as shown in FIG. 17, the curved piece 84 can be detached from the edge of the auxiliary vertical plate 89 at the lower end of the long hole 91 according to the elastic force of the third partial plate piece 82. Get involved. When the door body 42 reaches the open position, the third partial plate piece 82 of the rotation restricting member 76 is overlaid on the auxiliary vertical plate 89 as shown in FIG. The rotation of the door body 42 is restricted at the open position. The rotation of the door body 42 cannot continue beyond the open position. Excessive opening of the door body 42 is prevented. At the same time, in the curved piece 84, the second partial piece 86 gets over the lower end of the long hole 91. The first partial piece 85 is received by the lower end of the long hole 91. The rotation of the door body 42 is restricted in the opposite direction to that described above. Thus, the door body 42 can be held in the open position. The operator can continue to perform the maintenance work without being obstructed by the door body 42. The rotation restricting member 76 and the auxiliary vertical plate 89 constitute a rotation restricting mechanism in cooperation.

開き位置の扉体４２に閉じ位置に向かって回転駆動力が作用すると、湾曲片８４は第１部分片８５の傾斜面で長孔９１の下端に乗り上げる。扉体４２の回転力は第１部分片８５の傾斜面の働きで湾曲片８４に垂直方向駆動力を作用させる。湾曲片８４の垂直方向駆動力は第３部分板片８２の弾性変形を引き起こす。その結果、湾曲片８４は上方に変位する。こうして湾曲片８４は長孔９１から離脱することができる。扉体４２は閉じ位置に向かって鉛直軸回りで回転を継続することができる。 When a rotational driving force acts on the door body 42 in the open position toward the closed position, the curved piece 84 rides on the lower end of the long hole 91 on the inclined surface of the first partial piece 85. The rotational force of the door body 42 causes a vertical driving force to act on the curved piece 84 by the action of the inclined surface of the first partial piece 85. The vertical driving force of the curved piece 84 causes elastic deformation of the third partial plate piece 82. As a result, the curved piece 84 is displaced upward. Thus, the curved piece 84 can be detached from the long hole 91. The door body 42 can continue to rotate about the vertical axis toward the closed position.

前述の湾曲片８４に代えて、例えば図１９に示されるように、湾曲片８４ａが回転規制部材７６で用いられてもよい。開口８３の側端で第３部分板片８２の縁は鉛直方向に延びる。縁には湾曲片８４ａが接続される。湾曲片８４ａは第３部分板片８２から側板５４の表面を含む仮想平面に向かって延びる。 Instead of the curved piece 84 described above, a curved piece 84a may be used in the rotation restricting member 76 as shown in FIG. At the side end of the opening 83, the edge of the third partial plate piece 82 extends in the vertical direction. A curved piece 84a is connected to the edge. The curved piece 84 a extends from the third partial plate piece 82 toward a virtual plane including the surface of the side plate 54.

湾曲片８４ａは第１部分片８５ａおよび第２部分片８６ａを備える。第１部分片８５ａは第３部分板片８２に１鉛直線上で接続される。第１部分片８５ａは、第３部分板片８２から遠ざかるにつれて、支持板５１に沿って広がる第１基準平面５２に徐々に接近する。第１部分片８５ａは第３部分板片８２から最も遠ざかる位置に縁を形成する。縁は鉛直方向に延びる。縁には第２部分片８６ａが接続される。第２部分片８６ａは第３部分板片８２から遠ざかるにつれて前述の第１基準平面５２から徐々に遠ざかる。ここでは、前述と同様に、湾曲片８４ａ、板片７８および取り付け片７７は１枚の板材から成形される。成形にあたって例えば板金の折り曲げ加工が用いられる。 The curved piece 84a includes a first part piece 85a and a second part piece 86a. The first partial piece 85a is connected to the third partial plate piece 82 on one vertical line. The first partial piece 85 a gradually approaches the first reference plane 52 that spreads along the support plate 51 as it moves away from the third partial plate piece 82. The first partial piece 85a forms an edge at a position farthest from the third partial plate piece 82. The edge extends in the vertical direction. A second piece 86a is connected to the edge. The second partial piece 86a gradually moves away from the first reference plane 52 as it moves away from the third partial plate piece 82. Here, as described above, the curved piece 84a, the plate piece 78, and the attachment piece 77 are formed from a single plate material. For forming, for example, a sheet metal bending process is used.

このとき、補助垂直板８９には長孔９１ａが形成される。長孔９１ａは鉛直方向に直線的に延びる１対の縁で仕切られる。長孔９１ａの大きさは、回転規制部材７６の湾曲片８４ａの出入りを許容する程度に設定される。 At this time, a long hole 91 a is formed in the auxiliary vertical plate 89. The long hole 91a is partitioned by a pair of edges extending linearly in the vertical direction. The size of the long hole 91a is set to an extent that allows the curved piece 84a of the rotation restricting member 76 to enter and exit.

この室外機１５ではヒンジ片５８とヒンジ用開口７１との組み合わせに基づき扉体４２の回転軸９６は規定される。ここで、扉体４２の回転軸９６と第１部分片８５ａの縁との間には前述と同様に第４距離Ｄ４が設定される。扉体４２の回転軸９６と第２部分片８６ａとの間には第５距離Ｄ５が設定される。同時に、扉体４２の回転軸９６と長孔９１の縁との間には第６距離Ｄ６が設定される。第５距離Ｄ５は第６距離Ｄ６よりも小さく設定される一方で、第４距離Ｄ４は第６距離Ｄ６よりも大きく設定される。したがって、湾曲片８４ａは第２部分片８６ａの傾斜面で長孔９１ａの側端に押し付けられる。扉体４２がさらに開き位置に向かって回転すると、湾曲片８４ａは長孔９１ａの側端に乗り上げる。扉体４２の回転力は第２部分片８６ａの傾斜面の働きで湾曲片８４ａに水平方向駆動力を作用させる。湾曲片８４ａの水平方向駆動力は第３部分板片８２の弾性変形を引き起こす。その結果、湾曲片８４ａは扉体４２の回転軸９６に向かって変位する。湾曲片８４ａは長孔９１ａ内に受け入れられる。こうして湾曲片８４ａは第３部分板片８２の弾性力に応じて長孔９１ａの側端で補助垂直板８９の縁に離脱可能に係り合う。こういった構成によれば、天板３９が撓んで長孔９１ａが鉛直方向にずれても、湾曲片８４ａは確実に長孔９１ａに対して出入りすることができる。 In the outdoor unit 15, the rotation shaft 96 of the door body 42 is defined based on the combination of the hinge piece 58 and the hinge opening 71. Here, the fourth distance D4 is set between the rotating shaft 96 of the door body 42 and the edge of the first piece 85a in the same manner as described above. A fifth distance D5 is set between the rotation shaft 96 of the door body 42 and the second partial piece 86a. At the same time, a sixth distance D6 is set between the rotation shaft 96 of the door body 42 and the edge of the long hole 91. The fifth distance D5 is set to be smaller than the sixth distance D6, while the fourth distance D4 is set to be larger than the sixth distance D6. Therefore, the curved piece 84a is pressed against the side end of the long hole 91a by the inclined surface of the second partial piece 86a. When the door body 42 further rotates toward the open position, the curved piece 84a rides on the side end of the long hole 91a. The rotational force of the door 42 causes a horizontal driving force to act on the curved piece 84a by the action of the inclined surface of the second partial piece 86a. The horizontal driving force of the curved piece 84a causes elastic deformation of the third partial plate piece 82. As a result, the curved piece 84 a is displaced toward the rotation shaft 96 of the door body 42. The curved piece 84a is received in the long hole 91a. Thus, the curved piece 84a is detachably engaged with the edge of the auxiliary vertical plate 89 at the side end of the long hole 91a according to the elastic force of the third partial plate piece 82. According to such a configuration, even if the top plate 39 is bent and the long hole 91a is displaced in the vertical direction, the curved piece 84a can reliably enter and exit the long hole 91a.

その他、回転規制機構には例えば磁石および磁性体が用いられてもよい。例えば板片７８の第３部分板片８２に磁石が取り付けられる一方で、補助垂直板８９は磁性体から成形されればよい。磁石の働きで第３部分板片８２と補助垂直板８９との間には吸着力が作用する。その結果、扉体４２は開き位置に保持されることができる。 In addition, for example, a magnet and a magnetic body may be used for the rotation restricting mechanism. For example, while the magnet is attached to the third partial plate piece 82 of the plate piece 78, the auxiliary vertical plate 89 may be formed from a magnetic material. An attractive force acts between the third partial plate piece 82 and the auxiliary vertical plate 89 by the action of the magnet. As a result, the door body 42 can be held in the open position.
