In addition, since the electrical component box 30 is attached with the detachable flat plate 31 on the lower surface, maintenance of the electrical component box 30 from the lower surface is facilitated.

＜第２の実施例＞
図４〜図１０に第２の実施例の横壁埋込配置の場合のダクト型空気調和機の要部を示す。本実施例では室内機１０の吸込開口１２に取り付ける吸込ダクトとして、角型の吸込ダクト４０を使用する。この角型の吸込ダクト４０は、室内機１０の吸込開口１２に取り付けられる角ダクト４１と室内に向けて取り付けられる吸込グリル５０が取り付けられる吸込口ダクト４２とを筒形状に結合して構成され、吸込口ダクト４２を下部にしてスペーサ６０上に載置され、室内機１０を下部から支えている（図５、図８）。吸込ダクト４０上の室内機１０は、背面が奥壁５００に対して係止されることで、前方向に転倒しないようになっている。 <Second embodiment>
The main part of the duct type air conditioner in the case of the horizontal wall embedding arrangement of the second embodiment is shown in FIGS. In the present embodiment, a rectangular suction duct 40 is used as a suction duct attached to the suction opening 12 of the indoor unit 10. This rectangular suction duct 40 is configured by combining a rectangular duct 41 attached to the suction opening 12 of the indoor unit 10 and a suction inlet duct 42 to which a suction grill 50 attached to the room is attached in a cylindrical shape, It is placed on the spacer 60 with the inlet duct 42 at the bottom, and supports the indoor unit 10 from below (FIGS. 5 and 8). The back of the indoor unit 10 on the suction duct 40 is locked to the back wall 500 so that it does not fall forward.

スペーサ６０は、前壁４００の幅木４１０の高さに対応する高さを有し、床３００の上に設置されている（図５、図８）。また、吹出ダクト２０Ｂは室内機１０の吹出開口１１と室内に向けて取り付けられる吹出グリル７０との間に接続されている。   The spacer 60 has a height corresponding to the height of the baseboard 410 of the front wall 400, and is installed on the floor 300 (FIGS. 5 and 8). The blowout duct 20B is connected between the blowout opening 11 of the indoor unit 10 and the blowout grill 70 attached toward the room.

角ダクト４１は、図８に示すように、角ダクト４１に対して着脱可能なメンテナンス蓋４１ａを有する正面板４１ｂと、この正面板４１ｂに対向する背面板４１ｃと、図７に示すように、正面板４１ｂと背面板４１ｃの左側を接続する左側面板４１ｄと、正面板４１ｂと背面板４１ｃの右側を接続する右側面板４１ｅとで構成されている。背面板４１ｃの内壁には、図８、図１０に示すように、前記メンテナンス蓋４１ａに対面する位置に、フック４１ｆが取り付けられている。   As shown in FIG. 8, the square duct 41 includes a front plate 41b having a maintenance lid 41a that can be attached to and detached from the square duct 41, a back plate 41c that faces the front plate 41b, and as shown in FIG. The left side plate 41d connects the left side of the front plate 41b and the back plate 41c, and the right side plate 41e connects the right side of the front plate 41b and the back plate 41c. As shown in FIGS. 8 and 10, a hook 41f is attached to the inner wall of the back plate 41c at a position facing the maintenance lid 41a.

そして、その正面板４１ｂと背面板４１ｃの間には、左側面板４１ｄと右側面板４１ｅに跨るように、騒音抑制用の仕切板４３が取り付けられている。これにより、仕切板４３は吸込ダクト４０内を流通する吸込空気の流れと平行におかれることになる。この仕切板４３には、その正面と背面の両面に吸音材が貼付され、角ダクト４１内を通過する吸込空気流の振動により発生する騒音を吸収するようになっている。また、この仕切板４３は、横幅が角ダクト４１の横幅と同じであり、右側面板４１ｅの側の上部に四角形状の切欠き部４３ａが形成され、その切欠き部４３ａのほぼ中央から上方向に伸びるように、ガイド突起４３ｂが形成されている（図８〜図１０）。   And between the front board 41b and the back board 41c, the partition plate 43 for noise suppression is attached so that it may straddle the left side board 41d and the right side board 41e. Thereby, the partition plate 43 is placed in parallel with the flow of the suction air flowing through the suction duct 40. A sound absorbing material is attached to both the front and back surfaces of the partition plate 43 so as to absorb noise generated by vibration of the suction air flow passing through the rectangular duct 41. Further, the partition plate 43 has the same lateral width as that of the rectangular duct 41, and a rectangular cutout portion 43a is formed at the upper portion on the right side plate 41e side, and the upward direction from substantially the center of the cutout portion 43a. A guide protrusion 43b is formed so as to extend in the direction (FIGS. 8 to 10).

電装品箱３０は、図２では説明しなかったが、さらに平面板３３と対抗する側の平面板３６上において、その平面板３６の隣の平面板３１から遠い側にガイド孔３６ａが形成されている（図１０）。また、本実施例では、第１の開閉蓋としての平面板３１を閉じていたビスＢ１と同様なビスＢ４を、前記した平面板３４Ｂの着脱組立用に使用する。これにより、その平面板３４Ｂは第２の開閉蓋として機能する。   Although not explained in FIG. 2, the electrical component box 30 is further provided with a guide hole 36 a on the flat plate 36 on the side facing the flat plate 33 on the side far from the flat plate 31 next to the flat plate 36. (FIG. 10). Further, in this embodiment, a screw B4 similar to the screw B1 that has closed the flat plate 31 as the first opening / closing lid is used for attaching / detaching the flat plate 34B. Thereby, the flat plate 34B functions as a second opening / closing lid.

さて、本実施例では、角ダクト４１のメンテナンス蓋４１ａを図６に示す状態から図７に示すように取り外した状態で、図１０に示すように、電装品箱３０の平面板３６を下面として、その平面板３６のガイド孔３６ａを仕切板４３の切欠き部４３ａのガイド突起４３ｂに差し込む。さらにその電装品箱３０の平面板３５に取り付けた取付片３５ａを角ダクト４１の背面板４１ｄｃに取り付けたフック４１ｆに合わせてから、その取付片３５ａとフック４１ｆをビスＢ３で結合する。これにより、電装品箱３０は角ダクト４１の内部において、メンテナンス蓋４１ａの奥側で且つ室内機１０の吸込口１２から若干離れた下方に、装着される（図８、図９）。   Now, in this embodiment, with the maintenance lid 41a of the square duct 41 removed from the state shown in FIG. 6 as shown in FIG. 7, the flat plate 36 of the electrical component box 30 is used as the lower surface as shown in FIG. The guide hole 36 a of the flat plate 36 is inserted into the guide protrusion 43 b of the notch 43 a of the partition plate 43. Further, the mounting piece 35a attached to the flat plate 35 of the electrical component box 30 is aligned with the hook 41f attached to the back plate 41dc of the square duct 41, and then the mounting piece 35a and the hook 41f are coupled with the screw B3. As a result, the electrical component box 30 is mounted inside the rectangular duct 41, on the back side of the maintenance lid 41a and slightly below the suction port 12 of the indoor unit 10 (FIGS. 8 and 9).

このとき、図７、図８に示すように、メンテナンス蓋４１ａを取り外した状態で、電装品箱３０のビスＢ４を取り外すことにより、電装品箱３０の平面板３４Ｂを取り外すことができる。これにより、その電装品箱３０の配線接続等の作業を行うことができる。   At this time, as shown in FIGS. 7 and 8, the flat plate 34B of the electrical component box 30 can be removed by removing the screw B4 of the electrical component box 30 with the maintenance lid 41a removed. Thereby, operations such as wiring connection of the electrical component box 30 can be performed.

メンテナンス終了の後は、角ダクト４１の平面板３４ＢをビスＢ４で閉じてからメンテナンス蓋４１ａを閉じ、さらに前壁４００のメンテナンス扉４０２（図５）を閉じる。これにより、そのダクト型空気調和機全体は、縦姿勢の状態で前壁４００と奥壁５００の間に隠れることになる。   After completion of the maintenance, the flat plate 34B of the square duct 41 is closed with the screw B4, the maintenance lid 41a is closed, and the maintenance door 402 (FIG. 5) of the front wall 400 is further closed. Thus, the entire duct type air conditioner is hidden between the front wall 400 and the back wall 500 in a vertical posture.

以上のように、第２の実施例では、角型の吸込ダクト４０を構成する角ダクト４１の内部において、仕切板４３の上に位置するように電装品箱３０が支持されて搭載されるので、電装品箱３０の搭載用の特別のスペースを室内機の近傍に特別に確保する必要がない。しかもその電装品箱３０は角ダクト４１を通過する吸込空気流によって冷却されるので、電装品箱３０の発熱を抑制することができる。このとき、電装品箱３０は流路内に位置するが、その位置は室内機１０の吸込開口１２から離れた下方の位置であるので、室内機１０の吸込開口１２に吸い込まれる空気の流通が妨げられることもない。   As described above, in the second embodiment, the electrical component box 30 is supported and mounted so as to be positioned on the partition plate 43 inside the rectangular duct 41 constituting the rectangular suction duct 40. It is not necessary to secure a special space for mounting the electrical component box 30 in the vicinity of the indoor unit. Moreover, since the electrical component box 30 is cooled by the suction air flow that passes through the rectangular duct 41, heat generation of the electrical component box 30 can be suppressed. At this time, the electrical component box 30 is located in the flow path, but since the position is a lower position away from the suction opening 12 of the indoor unit 10, the flow of air sucked into the suction opening 12 of the indoor unit 10 is distributed. There is no hindrance.
