Abstract
본 고안은 에어콘 실외기에 관한 것으로, 종래 기술에 의한 사류팬에서는 팬의 입구부와 슈라우드 사이에 불안정한 와류(Vortex Flow)가 형성되어 공기의 유량이 저유량, 중유량, 고유량으로 갈수록 상승되는 이 와류에 의해 유동소음이 발생되는 문제점이 있었는 바, 사류팬(5)의 입구부측 단부와 슈라우드(7) 사이에 공기분리부재(10)를 설치하여 구성함을 특징으로 하는 본 고안에 의한 에어콘 실외기를 제공하여 공기분리부재(10)가 팬(5)의 회전에 의해 발생되는 입구부측 단부의 와류를 중간에서 끊어줌으로써 와류의 크기를 감소시켜 주게 되고, 이로 인하여 공기의 유동이 보다 안정적으로 흐를수 있도록 하는 것이며, 궁극적으로 입구부측의 와류의 크기가 감소되어 와류로 인한 소음을 저감시켜 주도록 한 것이다.The present invention relates to an air conditioner outdoor unit, and in a four-flow fan according to the prior art, an unstable vortex flow is formed between an inlet and a shroud of a fan so that an air flow rate rises toward a low flow rate, a heavy flow rate, and a high flow rate. There was a problem that the flow noise is generated by the vortex, the air conditioner outdoor unit according to the present invention, characterized in that the air separation member 10 is installed between the inlet side end and the shroud (7) of the vortex fan (5) The air separation member 10 reduces the size of the vortex by breaking the vortex at the inlet side end generated by the rotation of the fan 5 in the middle, thereby allowing the flow of air to flow more stably. Ultimately, the size of the vortex at the inlet side is reduced to reduce noise caused by the vortex.

본 고안은 에어콘 실외기의 사류팬에 관한 것으로, 특히 사류팬의 입구부에서 발생되는 와류의 크기를 감소시켜 이 와류로 인한 소음을 저감하도록 한 에어콘 실외기에 관한 것이다.The present invention relates to a vortex fan of an air conditioner outdoor unit, and more particularly, to an air conditioner outdoor unit that reduces noise caused by the vortex by reducing the size of the vortex generated at the inlet of the vortex fan.
일반적인 에어콘 실외기는 제1도에 도시한 바와같이, 에어콘 실외기 케이스(1)의 전면부에 설치되어 있는 그릴(2)의 내측으로 지지대(3)에 의해 고정된 모터(4)에 의해 구동되는 사류팬(5)이 회전가능하게 설치되어 있고, 그 내측으로는 열교환기(6)가 설치되어 있다.As shown in FIG. 1, a general air conditioner outdoor unit is driven by a motor (4) fixed by a support (3) to an inside of a grill (2) provided in a front portion of an air conditioner outdoor unit case (1). The fan 5 is rotatably provided, and the heat exchanger 6 is provided inward.
이와같이 구성되는 에어콘 실외기는 모터(4)가 구동되어 팬(5)이 회전되면, 전면그릴(2)을 통해 실내 공기가 유입되고, 유입된 공기는 열교환기(6)를 통과한 후, 슈라우드(7)를 거쳐 다시 전면그릴(2)을 통해 찬공기가 외부로 토출되는 것이다.When the air conditioner outdoor unit configured as described above is driven by the motor 4 and the fan 5 rotates, indoor air is introduced through the front grill 2, and the introduced air passes through the heat exchanger 6, and then the shroud ( After 7), cold air is discharged to the outside through the front grill (2).
그러나, 상기한 바와같은 종래 기술에 의한 사류팬에서는 제2도에 도시한 바처럼, 팬의 입구부와 슈라우드 사이에 불안정한 와류(Vortex Flow)가 형성되어 공기의 유량이 저유량, 중유량, 고유량으로 갈수록 상승되는 이 와류에 의해 유동소음이 발생되는 문제점이 있다.However, as described above, in the prior art swirl fan, as shown in FIG. 2, an unstable vortex flow is formed between the inlet of the fan and the shroud so that the flow rate of air is low, heavy, and high. There is a problem that the flow noise is generated by this vortex that rises toward the flow rate.
이러한 유동소음은 에어콘 셋트 전체의 소음을 증대시키는 원인으로 작용되었다.This flow noise acted to increase the noise of the entire air conditioner.
본 고안의 목적은 사류팬의 입구부에서 발생되는 와류의 크기를 감소시켜 이 와류로 인한 소음을 저감하려는 것이다.The purpose of the present invention is to reduce the noise caused by the vortex by reducing the size of the vortex generated at the inlet of the vortex fan.
이러한 본 고안의 목적을 달성하기 위하여, 사류팬의 입구부측 단부와 슈라우드 사이에 공기분리부재를 설치하여 구성함을 특징으로 하는 에어콘 실외기가 제공된다.In order to achieve the object of the present invention, an air conditioner outdoor unit is provided by installing an air separation member between the inlet end portion and the shroud of the crossflow fan.
상기 공기분리부재의 경사각(θ)은 30° 이내로 형성된 것을 특징으로 한다.The inclination angle θ of the air separation member is characterized in that formed within 30 °.
이하, 상기한 바와같은 본 고안에 의한 에어콘 실외기를 첨부도면에 도시한 실시예에 의거하여 보다 상세히 설명한다.Hereinafter, the air conditioner outdoor unit according to the present invention as described above will be described in more detail based on the embodiment shown in the accompanying drawings.
제3도는 본 고안에 의한 사류팬의 정면도이고, 제4도는 본 고안에 의한 에어콘 실외기의 구성도이며, 제5도는 본 고안에 의한 사류팬이 중량시 발생되는 유선 형태도로서, 이에 도시한 바와같이, 본 고안에 의한 에어콘 실외기는 사류팬(5)의 입구부측 단부와 슈라우드(7) 사이에 공기분리부재(10)를 설치하여 구성한 것이다.FIG. 3 is a front view of a vortex fan according to the present invention, and FIG. 4 is a block diagram of an air conditioner outdoor unit according to the present invention, and FIG. 5 is a streamline form diagram generated when the vortex fan according to the present invention is weighed. Likewise, the air conditioner outdoor unit according to the present invention is constructed by installing an air separation member 10 between the inlet side end portion of the swirling fan 5 and the shroud 7.
상기 공기분리부재(10)는 지지대(1)에 의해 슈라우드(7)에 고정되는 것이며, 경사각(θ)이 30° 이내로 경사지게 설치되어 있다.The air separation member 10 is fixed to the shroud 7 by the support 1, and the inclination angle θ is inclined within 30 degrees.
종래 기술 구성과 동일부분은 동일부호를 사용하였다.The same parts as those in the prior art configuration have the same reference numerals.
이와같이 구성되는 본 고안에 의한 에어콘 실외기의 작용 및 효과를 설명한다.The operation and effects of the air conditioner outdoor unit according to the present invention configured as described above will be described.
모터(4)가 구동되어 사류팬(5)이 회전되면, 그릴(2)을 통해 유입된 실내공기는 열교환기(6)를 거치면서 열교환되어 공기분리부재(10)에 의해 그 흐름이 상,하로 분리되어지면서, 슈라우드(7)와 사류팬(5)을 통과하여 외부로 토출되는 것이다.When the motor 4 is driven and the drift fan 5 is rotated, the indoor air introduced through the grill 2 is heat-exchanged while passing through the heat exchanger 6, and the flow thereof is increased by the air separation member 10. While being separated downward, it is discharged to the outside through the shroud (7) and the crossflow fan (5).
이때, 상기공기분리부재(10)는 팬(5)의회전에 의해 발생되는 입구부측 단부의 와류를 중간에서 끊어줌으로써 와류의 크기를 감소시켜 주게 되고, 이로 인하여 공기의 유동이 보다 안정적으로 흐를 수 있도록 하는 것이며, 궁극적으로 입구부측의 와류의 크기가 감소되어 와류로 인한 소음을 저감시켜 주는 것이다.At this time, the air separation member 10 is to reduce the size of the vortex by breaking the vortex of the inlet side end generated by the rotation of the fan 5 in the middle, so that the flow of air flows more stably Ultimately, the size of the vortex at the inlet side is reduced to reduce noise caused by the vortex.
이상에서 설명한 바와같이, 본 고안에 의한 에어콘 실외기는 공기분리부재가 설치되어 팬의 입구부와 슈라우드 사이에서 발생되는 와류를 감소시켜줌으로써 공기의 유동이 보다 안정적으로 이루어져 와류로 인한 소음이 저감되는 효과가 있다.As described above, the air conditioner outdoor unit according to the present invention is provided with an air separation member to reduce the vortex generated between the inlet and the shroud of the fan, the flow of the air is more stable, the effect of reducing noise due to vortex There is.
