従来の室内機の電装品箱として、 特開平 4一 2 3 6 0 2 4号公報に示されるよ うなベルマウスの外周部に配置されたものがある (図 2及び図 3に点線で示す電 装品箱 5 6を参照) 。  As a conventional electrical component box of an indoor unit, there is a box arranged on the outer periphery of a bell mouth as disclosed in Japanese Patent Application Laid-Open No. Hei 4 (1996) -234 (the dotted lines in FIGS. 2 and 3). Equipment box 56).
しかし、 上記の空気調和機の電装品箱では、 ベルマウスの外周部に電装品箱の 重量が作用して、 ベルマウスの上下位置が変化するおそれがある。一方、 遠心送 風機は、 ケ一シングの天面に装着されているため、 上下位置は一定に保たれてい る。 このため、 遠心送風機とベルマウスとの相対距離が所定の値から変化してし まい、 遠心送風機の送風性能が低下するおそれがある。  However, in the electrical component box of the air conditioner described above, the weight of the electrical component box may act on the outer peripheral portion of the bellmouth, and the vertical position of the bellmouth may be changed. On the other hand, since the centrifugal blower is mounted on the top of the casing, the vertical position is kept constant. For this reason, the relative distance between the centrifugal blower and the bell mouth may change from a predetermined value, and the blowing performance of the centrifugal blower may be reduced.
本発明の課題は、 天井埋設型または天井吊下型の空気調和機において、 遠心送 風機とベルマウスとの相対距離が所定の値に保たれるようにすることにある。 発明の開示 この発明の目的は、 天井埋設型または天井吊下型の空気調和機において、 遠心 送風機とベルマウスとの相対距離が所定の値に保たれるようにすることにある。 請求項 1に記載の空気調和機は、 天井埋設型または天井吊下型の空気調和機で あって、 ケ一シングと、 遠心送風機と、熱交換器と、 ベルマウスと、 電装品が収 納された電装品箱とを備えている。 ケーシングは、 内部に空気を吸入するための 吸入口と、 外部に空気を吹き出すための複数の吹出口とを備えている。 吸入口は 、 ケ一シングの下面に設けられている。遠心送風機は、 ケーシングの内部におい て、 吸入口の上側に配置されている。熱交換器は、遠心送風機を囲むように配置 されている。複数の吹出口は、熱交換器の外周側に配置されている。 ベルマウス は、 吸入口と遠心送風機との間に配置されている。 電装品箱は、 ケ一シングの天 面に装着されている。 It is an object of the present invention to provide a ceiling-mounted or ceiling-suspended air conditioner in which a relative distance between a centrifugal blower and a bell mouth is maintained at a predetermined value. Disclosure of the invention An object of the present invention is to maintain a relative distance between a centrifugal blower and a bell mouth at a predetermined value in a ceiling-mounted or ceiling-suspended air conditioner. The air conditioner according to claim 1 is a ceiling-mounted or ceiling-suspended type air conditioner, which stores casing, a centrifugal blower, a heat exchanger, a bellmouth, and electrical components.
