Abstract

본 발명은 선풍기에 관한 것으로서, 더 자세하게는 선풍기본체를 고정시킨 상태에서 풍향을 가변시킬 수 있도록 한 선풍기에 관한 것이다.The present invention relates to a fan, and more particularly, to a fan capable of varying the wind direction in a state where the fan base is fixed.

종래의 선풍기(1)로서 풍향을 가변시키고자 할 시에는 상기 헤드부(20)와 송풍팬(30), 그리고 보호망(40)이 동시에 회전하기 때문에 이들의 회전공간이 필요할 뿐만 아니라, 이들을 회전시키는 데에 만은 힘이 필요하다는 문제점이 있었다.In order to change the direction of the wind as a conventional fan (1), because the head portion 20, the blowing fan 30, and the guard net 40 rotates at the same time, not only their rotation space is required, but also to rotate them There was a problem that de only need strength.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로서, 상기 선풍기는 그대로 고정시킨 상태에서 회전날개 전방의 풍향가이드를 회전시켜 풍향을 가변시키므로서, 선풍기의 설치공간을 최소화시키는 동시에 풍향을 가변시키는데 소요되는 구동력을 극소화시킨 선풍기를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the conventional problems as described above, while varying the wind direction by rotating the wind direction guide in front of the rotary blade in a fixed state, while minimizing the installation space of the fan It is an object of the present invention to provide a fan that minimizes the driving force required to change the wind direction.

상기의 목적을 달성하기 위하여 본 발명은 제2도와 같이 소정의 통기공(112)이 구비된 안내공간부(111)를 형성한 다음, 상기 안내공간부(111) 중앙에 설치홈부(113)를 형성하고, 그 후방에 흡입구(114)를 형성하여 된 본체(110)와; 상기 본체(110) 내측에 설치되는 구동수단(121)을 구비한 송풍팬(120)과; 상기 구동수단(121)의 구동축(122)단부와 연동되게 설치되는 복수의 기어(131)(132)(133)(134)로 구성된 구동기어군(130)과; 상기 구동기어군(130)에 의해 안내공간부(111)내측에서 제자리회동하면서 본체(110)전방으로 바람을 가변시키는 풍향가이드(140)등으로 구성한 것이다.In order to achieve the above object, the present invention forms a guide space 111 having a predetermined ventilation hole 112 as shown in FIG. 2, and then installs an installation groove 113 in the center of the guide space 111. A main body (110) formed at the rear of the suction port (114); A blowing fan 120 having a driving means 121 installed inside the main body 110; A drive gear group 130 composed of a plurality of gears 131, 132, 133, and 134 which are installed to be interlocked with the drive shaft 122 end of the drive means 121; The drive gear group 130 is configured as a wind direction guide 140 for varying the wind to the front of the main body 110 while rotating in place in the guide space 111.
