Abstract

본 발명은 날개의 중앙으로 모터방열팬을 설치하여 날개의 풍향과 반대 방향으로 공기가 토출되도록 함으로서, 모터가 회전되는 동안 날개의 전방으로부터 흡입된 일부 공기가 모터쪽으로 토출되어 모터가 방열되고 이때 발생되는 열기가 사용자쪽으로 향하지 않도록 한 선풍기의 모터 방열장치에 관한 것으로서, 특히 좌대상부에 모터가 설치되고 또한 모터의 회전축에 날개 중앙의 허브가 끼워진 상태에서 고정캡으로 고정설치되고 또한 날개는 전,후방안전망으로 감싸진 선풍기에 있어서, 상기 허브 중앙에 형성되어 상기 회전축에 끼워지는 축받이, 그리고 상기 축받이 외주면과 상기 허브 내주면 사이에 방사상으로 다수개 형성되어 상기 모터 쪽으로 풍향을 발생시키는 모터 방열팬이 구비된 특징이 있다.The present invention is to install a motor heat radiating fan in the center of the blade so that the air is discharged in the direction opposite to the wind direction of the blade, while some of the air sucked from the front of the blade while the motor is rotated is discharged toward the motor to dissipate the motor at this time The present invention relates to a motor heat dissipation device of a fan that prevents heat from being directed toward the user, and in particular, the motor is installed in the left target part, and is fixedly fixed with a fixed cap while the hub at the center of the wing is fitted to the rotating shaft of the motor. In the fan wrapped with a safety net, the bearing is formed in the center of the hub and fitted to the rotary shaft, and a plurality of radial radiating fan is formed between the bearing outer peripheral surface and the hub inner peripheral surface to generate a wind direction toward the motor There is a characteristic.

Claims

The fan is installed in the left target part and is fixedly installed with a fixed cap while the hub of the blade center is fitted to the rotating shaft of the motor, and the blade is formed at the center of the hub 21 in the fan wrapped with the front and rear safety nets. A motor radiating fan 23 radially formed between the bearing 22 fitted to the rotating shaft 12 and the outer peripheral surface of the bearing 22 and the inner peripheral surface of the hub 21 to generate a wind direction toward the motor 11. Motor radiator of the fan having a.

The suction hole (19) formed in communication with the motor heat radiating fan (23) on the outer circumferential surface of the fixing cap (24), and the suction in the cap (18) installed at the center of the front safety net (16). The fan heat sink of the fan, characterized in that it comprises a suction hole (19) formed to correspond to the ball (25).
