Abstract

Abstract Translated from Japanese (57)【要約】 (修正有) 【目的】電動機をより効率的に冷却することができ、よ り効率の高い遠心送風機を得る。 【構成】外径が円筒形を成し、一側方の中央部に吸気口 3を備え、他側方に排気口4を備えた遠心ファン部F と、この遠心ファン部Fを収容した筒形ケーシングC と、この筒形ケーシングC内で、遠心ファン部Fの吸気 口3側に収容配置し、この筒形ケーシングCの内径より も小径の外径を有し、遠心ファン部Cを回転駆動する電 動機Mとを備える。そして、筒形ケーシングCの電動機 Mを配置した側を吸込口1とし、筒形ケーシングCの遠 心ファン部Fを配置した側を吐出口2とする。 (57) [Summary] (Modified) [Purpose] To obtain a centrifugal blower that can cool an electric motor more efficiently and has higher efficiency. [Structure] Centrifugal fan unit F having a cylindrical outer diameter, having an intake port 3 in the central portion on one side and an exhaust port 4 on the other side. And a cylindrical casing C accommodating the centrifugal fan unit F And an electric motor for accommodating and arranging the centrifugal fan portion F on the intake port 3 side in the tubular casing C, having an outer diameter smaller than the inner diameter of the tubular casing C, and rotatingly driving the centrifugal fan portion C. M and. The side of the cylindrical casing C on which the electric motor M is arranged is the suction port 1, and the side of the cylindrical casing C on which the centrifugal fan part F is arranged is the discharge port 2.
