Abstract

모터내장형의 송풍기의 케이싱의 측판의 구조를 개량하여, 모터의 내주 혹은 제어회로부로의 물방울 등의 침입을 방지할 수 있는 케이싱구조를 제공한다.A casing structure capable of improving the structure of a side plate of a casing of a blower of a motor built-in type and preventing intrusion of water droplets into the inner periphery of the motor or the control circuit portion.

케이싱의 모터의 고정자측을 장치한 측판의 분출구측의 모터상방에, 분출구로부터 동축판을 거쳐서 침입하여 오는 물방울을 받기 위해 차양부 (1d)를 형성하였다. 분출구(30)로부터 물방울이 케이싱내로 침입하고 측판(1b)을 거처셔 아래쪽으로 이동하더라고, 그 물방울은 케이싱의 개구부에 형성한 접어구부림부(1d)「차양부」로 받아 멈추어지고,그후는 접어구부림부(1d)를 따라서 아래쪽으로 이동하기 때문에 물방울이 모터내장 송풍기의 기판에 침입하는 것을 방지할 수 있다.A flange portion (1d) is formed above the motor on the side of the jetting port of the side plate on which the stator side of the motor of the casing is mounted, in order to receive water droplets coming from the jetting port through the coaxial plate. The water droplet enters the casing from the jet port 30 and moves downward along the side plate 1b. The water droplet is stopped and received by the folded bent portion 1d "shoulder" formed in the opening of the casing, It moves downward along the bending portion 1d, so that it is possible to prevent water droplets from entering the substrate of the motor built-in blower.
