Abstract

본 발명은 전동팬에 있어서 모터의 과열을 방지하는 것을 목적으로 하는 것으로, 그 구성은 열기를 내보내는 팬(2)의 케이싱(4)에 모터(3)를 간격을 두어 부착하는 것에 있어서, 도풍판(10)에 평판부(17)와 통형상부(18)를 형성하여 유입부(271)를 갖는 통풍로(27)를 형성하고, 상기 통풍로(27)를 케이싱(4)의 중심에 연통시키고 또 평판부(17)를 모터의 앞벽(25)에 근접시켜 배치하는 것이다. 팬(2)의 흡인력에 의하여 외기가 유입부(271)에서 흡인되어 모터의 앞벽(25)을 냉각하는데, 유입부(271)에서는 공기는 좁은 곳을 고속으로 흐르기 때문에 공기의 단위용적당의 접촉면적이 크고 냉각작용이 크다. 또한 평판부(17)는 고온의 팬에서 떨어져 있기 때문에 수열량(受熱量)이 적다.An object of the present invention is to prevent overheating of a motor in an electric fan. The configuration of the present invention is to provide a guiding plate for attaching the motor 3 to the casing 4 of the fan 2 through which heat is released. A flat plate portion 17 and a cylindrical portion 18 are formed at 10 to form a ventilation passage 27 having an inflow portion 27 1 , and the ventilation passage 27 is formed at the center of the casing 4. It communicates and arrange | positions the flat plate part 17 near the front wall 25 of a motor. The outside air is sucked by the inlet part 27 1 by the suction force of the fan 2 to cool the front wall 25 of the motor. In the inlet part 27 1 , the air flows through a narrow place at high speed, so that Has a large contact area and a large cooling effect. In addition, since the flat plate portion 17 is separated from the hot pan, the heat quantity is low.
