この室外機 3では、電装品ユニット 5の端子板 53に接続された配線を遮蔽板 6の遮 断壁配線支持部 622によって、ほぼ隙間無く支持することができる。このために、虫 が機械室 36に入り込みに《なる。このため、虫が機械室 36内に入り込むことで引き 起こされる可能性のある弊害(例えば、電位差の異なる配線間に虫などが入り込んで 短絡することによる故障)を防止できる。また、遮蔽板 6が不燃性素材によって形成さ れており、遮断壁 62によって電装品ユニット 5側と外部側とを遮断できるために、電 装品ユニット 5などが発火した場合であっても、外部側に燃え移りに《することができ る。樹脂製カバー 313を遮蔽板 6の外部に配置しているために完全に外部から雨や 水などが入り込みに《なる。さらに、遮蔽板 6は不燃性樹脂素材によって形成されて V、るために複雑な形状であっても製造しやすレ、。 In the outdoor unit 3, the wiring connected to the terminal plate 53 of the electrical component unit 5 can be supported by the shielding wall wiring support part 622 of the shielding plate 6 with almost no gap. For this reason, insects enter the machine room 36. For this reason, it is possible to prevent harmful effects that may be caused by insects entering the machine room 36 (for example, failure due to insects entering between wires having different potential differences and short-circuiting). In addition, since the shielding plate 6 is made of a non-combustible material and the shielding unit 62 can shield the electrical component unit 5 side from the external side, even if the electrical component unit 5 ignites, It can be burned out to the outside. Since the resin cover 313 is disposed outside the shielding plate 6, rain, water, etc. will completely enter from the outside. In addition, the shielding plate 6 is made of non-combustible resin material V, so it is easy to manufacture even for complicated shapes.
[0021] この電装品ユニット 5の支持部材 51は、電装品 52を支持する配置部 511と、配置 部 51 1からケーシング 31の端部に向かって突出する突出部 512を有し、突出部 512 にリアクタ 521が取り付けられているために、電装品 52とリアクタ 521とを近い位置に 酉己置すること力できる。このために、電装品 52とリアクタ 521とを一つのユニットとして 扱うことができ、設計の自由度が増す。さらに、電装品 52から離れた位置であって電 装品 52の上側にリアクタ 521を配置するために、リアクタ 521が発熱した場合であつ ても他の電装品 52に影響を与えにくくなる。そして、電装品ュュット 5に端子板 53を 配置することができるために、配線などの材料を削減することができ、コストを抑えるこ とができる。配置部 511に支持された電装品 52の下側端部の高さ位置が、下方板状 部 513の下側端部の高さ位置とほぼ同じ位置であるために、机などに電装品ユニット 5を置く場合に電装品ユニット 5の姿勢を図 2のような姿勢に保つことができる。また、 支持部材 51が防炎素材によって形成されているために、電装品 52が発火した場合 であっても、他の部材に影響を与えに《することができる。
[0021] The support member 51 of the electrical component unit 5 includes a disposition portion 511 that supports the electrical component 52, and a protrusion portion 512 that protrudes from the disposition portion 511 toward the end portion of the casing 31. Since the reactor 521 is attached to the electric component 52, the electric component 52 and the reactor 521 can be placed close to each other. For this reason, the electrical component 52 and the reactor 521 can be handled as one unit, and the degree of design freedom increases. Furthermore, since the reactor 521 is disposed at a position away from the electrical component 52 and above the electrical component 52, even when the reactor 521 generates heat, the other electrical component 52 is hardly affected. And since the terminal board 53 can be arrange | positioned to the electrical component mute 5, materials, such as wiring, can be reduced and cost can be held down. Since the height position of the lower end portion of the electrical component 52 supported by the arrangement portion 511 is substantially the same as the height position of the lower end portion of the lower plate-shaped portion 513, the electrical component unit can be mounted on a desk or the like. When placing 5, the posture of the electrical component unit 5 can be maintained as shown in FIG. Further, since the support member 51 is formed of a flameproof material, even when the electrical component 52 is ignited, other members can be affected.
