吐出方向変更が可能な遠心ファンに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifugal fan used for building air-conditioning equipment, etc., and particularly to the discharge direction in three directions of left and right and above without changing the position of the connection duct of the suction port. The present invention relates to a centrifugal fan that can be changed.

【従来の技術】遠心ファンは、吐出方向の種類が多く、
その吐出方向毎に異なる機種を製作すると機種数が多く
なって製品標準化の妨げとなっている。2. Description of the Related Art Centrifugal fans have many types of discharge directions,
If different models are manufactured for each discharge direction, the number of models increases, which hinders product standardization.
【０００３】このような点を改善するため、ファン全体

更を一機種で対応できるものが提案されている（特開昭
５８−１３１４００号公報参照）。In order to improve such a point, by installing the entire fan by rotating it by 90 °, it is possible to change the discharge direction to the left and right and to the upper side by one model without performing the work such as disassembling and assembling. One has been proposed (see JP-A-58-131400).

くなるという問題がある。In the above-mentioned prior art, since the electric motor is built in the fan casing, the size of the entire fan becomes large, and the discharge direction of the fan and the electric motor is integrally changed. It becomes large and it is difficult to change the actual discharge direction. Moreover, since the electric motor is mounted vertically or is hung upside down except for the discharge direction shown in FIG. 4, there is a problem that workability is deteriorated in maintenance and inspection of the electric motor.

すなわち、前記の従来技術は、据付性に対する配慮が不
足している。Further, in this conventional technique, when the discharge direction is changed, the height position of the suction port is changed, so that there is a problem that it is difficult to cope with a change in installation plan.
That is, in the above-mentioned conventional technology, consideration for installation is insufficient.

を得ることができる。Since the centrifugal fan of the present invention has the above-described structure, it is of course possible to change the discharge direction to the right, up, and left directions, but in any case, the suction phase is changed. Since the height of the flange does not change, it is possible to change the discharge direction without changing the position of the suction port connection duct.
It is possible to obtain a centrifugal fan that is easy to use and that is easy to install and plan.
