Abstract

본 발명은 풍향이 여러 각도로 절환되도록 하여 인원이 적을 때 작은 각도로 절환되고 또한 인원이 상대적으로 많을 때 넓은 범위로 절환되도록 함으로서, 불필요한 부분으로 바람이 토출되지 않도록한 선풍기의 풍향 절환장치에 관한 것으로서, 특히 모터 하부의 중심축에 중공상의 슬리브가 끼워져 좌대 상단의 네크부에 결합되고 또한 모터 후방으로 형성된 회전축의 워엄기어와 치합되는 중공상의 워엄휠에 끼워져 하강될 때 일체로 회전되는 승강축을 갖는 풍향절환장치에 있어서, 상기 승강축 하단에 형성된 구동기어가 단계적으로 하강될 때 이와 단계적으로 치합되는 제1,제2종동기어, 그리고 상기 슬리브의 양으로 형성된 레버와 상기 제1,2종동기어를 각각 연결하는 링크가 구비된 특징이 있다.The present invention relates to a wind direction switching device of the fan that is switched to a small angle when the number of people is small so that the wind direction is switched at various angles and to a wide range when the number of people is relatively large, so that the wind is not discharged to unnecessary parts In particular, it has a lifting shaft that is integrally rotated when the hollow sleeve is fitted to the central shaft of the lower part of the motor is coupled to the neck portion of the upper seat and fitted to the hollow worm wheel engaged with the worm gear of the rotating shaft formed to the rear of the motor. In the wind direction switching device, the first and second driven gears and the first and second driven gears are formed in the amount of the sleeve and the first and second driven gears to be engaged stepwise when the driving gear formed on the lower end of the lifting shaft is lowered step by step; There is a feature that each has a link to connect.
