Abstract

과제assignment

팬의 측판 혹은 원통상의 보스부 평면에 회전중심과 대략 동심의 원주상에 긴 구멍을 설치하고, 이들 긴 구멍의 작용에 의하여 운전시에 발생하는 전자진동음을 해소한다.Long holes are provided in the side plate of the fan or in the plane of the cylindrical boss part, in the circumference of the center of rotation and approximately concentric, and the electromagnetic vibration generated during operation is eliminated by the action of these long holes.

해결수단Solution

팬을 케이싱내에 배치하고, 동시에 그 팬을 회전구동함으로서 케이싱에 형성한 벨 마우스로부터 공기를 흡입하여 케이싱에 형성한 토출구로부터 공기를 토출하는 송풍기로서, 상기 팬의 벨 마우스 축과는 반대측의 측판에 회전축과 거의 동심의 반경이 다른 복수의 원주(Rl,R2)상에 적어도 3개 이상의 긴 구멍(9a,9b)을 각각 형성함과 동시에, 상기 다른 원주상의 각 긴 구멍은 반경이 다른 원주상의 긴 구멍과 서로 지그재그상으로 배치되어 있는 것을 특징으로 하는 송풍기이다.A fan is disposed in the casing, and at the same time by rotating the fan to suck air from the bell mouth formed in the casing to discharge the air from the discharge port formed in the casing, the fan on the side plate opposite to the bell mouth axis of the fan At least three elongated holes 9a and 9b are formed on a plurality of circumferences Rl and R2, each of which has a radius substantially concentric with the axis of rotation, and at the same time, each elongated hole on the other circumference has a circumference with a different radius. The blower is characterized in that it is arranged in a zigzag shape with a long hole of.

Description

송풍기air blower

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 실시형태인 송풍기의 케이싱과 다익팬과의 관계를 도시하는 측면도이다, 제2도는 다익팬의 메인판의 정면도 및 측면도이다, 제3도는 본 발명과 종래품과의 소음비교도이다, 제4도는 긴 구멍의 단부를 반경방향(A화살표 방향)으로 보았을 때에 대략 일치시킨 상태의 메인판의 정면도 및 측면도이다, 제5도는 보스를 갖지 않는 평판인 메인판에 반경이 다른 원주상에 긴 구멍을 설치한 메인판의 정면도 및 측면도이다.1 is a side view showing a relationship between a casing of a blower according to an embodiment of the present invention and a multi-wing fan, FIG. 2 is a front view and a side view of the main plate of the multi-wing fan, and FIG. 3 is a noise between the present invention and a conventional product. FIG. 4 is a front view and a side view of the main plate in a state where the end of the long hole is roughly matched when viewed in the radial direction (A arrow direction). FIG. 5 is a radius of the main plate which is a flat plate having no boss. It is a front view and a side view of the main board which provided the long hole on another circumference.
