본 고안은 자동차공조기용 시로코팬에 관한 것으로서, 더욱 상세히는 기능을 개선한 자동차공조장치에 사용되는 공조팬에 관한 것이다.The present invention relates to a sirocco fan for an automotive air conditioner, and more particularly, to an air conditioning fan for use in an automotive air conditioner having improved functionality.
자동차의 공조시스템에서는 공조통로내로 공기를 흡입하기 위하여 모우터에 의하여 구동되는 흡입팬이 사용되며 이러한 흡입팬은 통상 시로코팬(Sirocco Fan)이라는 팬을 사용하고 있다. 이러한 시로코팬이 제 1 도와 2 도에 도시된다.In an air conditioning system of a vehicle, a suction fan driven by a motor is used to suck air into the air conditioning passage, and this suction fan generally uses a fan called a Sirocco Fan. Such a sirocco fan is shown in the first and second degrees.
통상적인 시로코팬(1)은 공기의 흡입을 측방에서 하여 상방으로 배출하기 위하여 다수의 축방향 원주상태로 부착되는 다수개의 팬블레이드(2)를 양단의 림(Rim)(3)사이에 형성하고 일측 하방이 중실된 형상의 팬이다.A conventional sirocco fan (1) forms a plurality of fan blades (2) between the rims (3) at both ends, which are attached in a plurality of axial circumferential states in order to discharge the air upward from the side by suction of air. One side is a fan of the solid shape.
이러한 통상의 시로코팬(1)은 림(3)의 단부에까지 팬블레이드(2)가 연장하여 일체로 형성된다.This conventional sirocco fan 1 is formed integrally by extending the fan blade 2 to the end of the rim (3).
공조시스템에서는 특히 소음이나 진동의 유발이 억제된 설계를 원하며, 상기의 시로코팬은 비교적 적합한 것으로 사료되나, 종래의 상기 형상의 시로코팬(1)은 하기와 같은 문제점을 가진다.In the air conditioning system, the design of suppressing the occurrence of noise or vibration is particularly desired, and the sirocco fan is considered to be relatively suitable, but the conventional sirocco fan 1 has the following problems.
풍향이 변경되는 팬블레이드단부 즉, 림(3)측에서는 풍속이 어느정도 있는 바람이 유입되면 림단부에서의 바람과 인출되는 바람이 충돌하게 되어 풍속이 저하되고 또한 마치 병입구에 바람을 불면 소리가 유발되는 것과 같이 풍속에 의한 마찰음이 발생하게 되어 소음과 진동의 원인이 된다.At the fan blade end where the wind direction is changed, that is, the rim (3) side, if the wind with a certain wind speed is introduced, the wind from the rim end and the wind drawn out collide with the wind speed, and the sound is generated when the wind blows at the bottleneck. As can be seen, the noise generated by the wind speed causes noise and vibration.
상기와 같은 문제점을 해결하기 위하여 본 고안에서는 형상과 구조를 변경한 시로코팬을 제공함으로써 상기한 문제점을 일소하는 것을 목적으로 한다.In order to solve the above problems, the present invention aims to obviate the above problems by providing a sirocco fan with a changed shape and structure.
이하의 부수된 도면과 함께 본 고안의 자동차공기용 시로코팬을 더욱 상세하게 설명한다.The sirocco fan for automobile air of the present invention together with the accompanying drawings will be described in more detail.
본 고안의 시로코팬(10)은 다수의 축방향 원주형태로 부착되는 다수개의 팬블레이드(11)의 양단부를 제 4 도에 도시한 바와 같이 내측으로 단이져 만입한 형상으로 구비하도록 단부(12)를 가지는 것을 특징으로 한다.The sirocco fan 10 of the present invention has an end portion 12 having both end portions of a plurality of fan blades 11 attached in a plurality of axial circumferences in a stepped shape inwardly as shown in FIG. Characterized in having a.
상기와 같이 팬블레이드(11)를 형성함으로써 림(3)이 형성하는 단부의 평면과 팬블레이드(11)가 형성하는 내측면과는 일종의 대피공간이 발생하여 2개의 다른 성격의 풍속(風束)이 혼합되게 되어 상기한 문제를 최소화할 수 있고 중량을 저하시키는 부가적인 역할도 수행할 수 있는 것이다.By forming the fan blades 11 as described above, a kind of evacuation space is generated between the plane of the end formed by the rim 3 and the inner surface formed by the fan blades 11, thereby creating two different wind speeds. This mixing can minimize the above problems and can also play an additional role of reducing weight.
상기와 같은 본 고안의 자동차공조기용 시로코팬은 팬블레이드의 형상을 변경함으로써 종래의 소음과 진동이 유발되는 문제점을 극소화할 수 있는 유용한 고안인 것이다.The sirocco fan for the automotive air conditioner of the present invention as described above is a useful design that can minimize the problems caused by the conventional noise and vibration by changing the shape of the fan blade.
