Description

선풍기의 강풍 날개Strong wind wing of electric fan

제1도는 본 고안을 설치한 선풍기.1 is a fan installed the present invention.

제2도는 본 고안의 측면도.2 is a side view of the present invention.

본 고안은 가정이나 직장에서 더위를 이겨내기 위하여 사용되는 선풍기의 강풍 날개에 관한 거승로 날개를 외줌녀에 부착하게 된 몸체 외주면에 4개의 날개를 부착하되 2개씩 조를 편성하여 2개의 날개를 몸체 전방에 나머지 2개의 날개는 몸체 부착하여 후방 날개가 송풍한 바람을 전방 날개가 받아 재차 송풍하게 함으로써 저회전으로도 바람을 멀리 송풍하게 하여 전력소모를 적게 함을 목적한 것이다.The present invention attaches four wings to the outer circumference of the body, which attaches the wings to the maternal and daughter, in order to overcome the heat at home or at work. The remaining two wings are attached to the body and the front wing receives the wind blown by the rear wing and blows it again so that the wind can be blown away even at low rotations to reduce power consumption.

종래에는 몸체 외주면에 날개가 일렬로 부착되어 있어 4개의 날개가 고르게 바람을 송풍하는 관계로 그 송풍력이 일정하여 멀리 송풍시킬때에는 회전력을 높여 주어야 되었으며 회전력을 높여 주게 됨에 따라 많은 량의 전력 소모를 필요하게 되는 결점이 있었던 것이다.Conventionally, since the wings are attached to the outer circumference of the body in a row, the four wings evenly blow the wind, so the blowing force is constant. There was a defect that was needed.

본 고안은 이와 같은 결점을 시정하기 위하여 안출한 것으로 첨부 도면에 의하여 그 구조를 상세히 설명하면 다음과 같다.The present invention has been devised to correct such drawbacks and the structure thereof will be described in detail with reference to the accompanying drawings.

날개를 외주면에 방사선상으로 부착하게 된 몸체(1)외주면에 전방 날개(2)(2')와 후방 날개(3)(3')을 부착 형성하되 전방 날개(2)(2')는 몸체(1) 외주면의 전방지점선(4)에 따라 좌우 대향되게 부착하고 후방날개(3)(3')는 몸체(1) 외주면의 후방지점선(5)에 따라 상하 대향되게 부착 형성하여서 구성된 것이다.The front wing (2) (2 ') and the rear wing (3) (3') are attached to the outer circumferential surface of the body (1), which radially attaches the wing to the outer circumferential surface. (1) Attached to the left and right facing the front point line (4) of the outer peripheral surface and the rear wing (3) (3 ') is configured to be formed to face up and down along the rear point line (5) of the outer peripheral surface of the body (1). .

도면 중 미설명부호 6는 선풍기의 모우터이다.In the figure, reference numeral 6 is a motor of the fan.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

즉, 모우터(6)의 회전력에 의하여 몸체(1)가 회전할시 전바 날개(2)(2')와 후방 날개(3)(3')가 선풍기 전방으로 송풍하게 되는 것은 종래 것과 같으나, 후방 날개(3)(3')가 보낸 바람을 받아 송풍하게 됨으로 그 송풍력이 강하여져 바람을 멀리 보낼수 있게 된 것이다.That is, when the body 1 rotates by the rotational force of the motor 6, the front blades 2, 2 'and the rear blades 3, 3' blows to the front of the fan as in the prior art, The rear wing (3) (3 ') is to receive the wind sent by the air blowing force is stronger that the wind can be sent away.

이와 같이 본 고안은 몸체(1)에 전방 날개(2)(2')와 후방날개(3)(3')를 구분하여 부착하였으므로 일차적으로 후방 날개(3)(3')가 바람을 일으켜 앞으로 보내게 되고 이 바람을 받아 전방 날개(2)(2')가 재차 송풍하게 됨으로 그 송풍력이 자연히 강하여져 바람을 멀리 송풍하게 되는 장점이 있어 모우터(6)의 저회전으로도 종래의 것과 같이 사용하게 되는 효과가 있고 이에 따라 전력소모가 낮아 경제적인 잇점이 있는 것이다.As such, the present invention separately attaches the front wings 2, 2 'and the rear wings 3, 3' to the body 1, so that the rear wings 3, 3 'are primarily caused by the wind. Since the front wing (2) (2 ') is blown again by receiving this wind, the blowing force is naturally strong, and the wind is blown away.Therefore, even with the low rotation of the motor 6, There is an effect that can be used together, and accordingly the power consumption is low, there is an economic advantage.

도시한 바와같이 날개를 부착하게 된 종래 것의 몸체(1) 외주면에 전방지점선(4)에 따라 전방날개(2)(2')를 좌우 대향으로 부착하고 후방 지점선(5)에 따라 후방 날개(3)(3')를 상하 대향으로 부착하여서 된 선풍기의 강풍날개.As shown in the drawing, the front wings 2, 2 'are attached to the outer peripheral surface of the body 1 of the prior art to which the wings are attached in the left and right directions along the front point line 4, and the rear wing along the rear point line 5. (3) Strong wind vanes of fans installed by attaching (3 ') up and down.
