본 고안은 분리형 룸에어콘의 실외기에 관한 것으로서, 특히 팬의 지지구조를 개선하여 소음을 저감시켜 주는 에어콘 실외기의 송풍팬 지지구조에 관한 것이다.The present invention relates to an outdoor unit of a separate room air conditioner, and more particularly, to a blower fan support structure of an air conditioner outdoor unit, which reduces noise by improving a fan support structure.
종래 에어콘 실외기의 송풍팬 지지구조는 제1도에서 도시되는 바와 같이, 송풍구멍이 형성되는 쉬라우드(1)에 브라켓(2)이 고정 되고, 브라켓(2)중심부에 팬모터(3)의 외주면이 고정되며, 쉬라우드(1)의 송풍구멍에서 회전 가능하도록 팬모터(3)의 회전축에 송풍팬(4)이 체결되어 있다. 또한, 브라켓(2)외측에는 보호망(미도시)이 취부되어 있다.As shown in FIG. 1, the blower fan supporting structure of the conventional air conditioner outdoor unit has a bracket (2) fixed to the shroud (1) in which the blow holes are formed, and the outer peripheral surface of the fan motor (3) in the center of the bracket (2) The blower fan 4 is fastened to the rotating shaft of the fan motor 3 so as to be rotatable in the blower hole of the shroud 1. In addition, a protective net (not shown) is attached to the outside of the bracket 2.
여기서, 브라켓(2)은 제2도에서 도시되는 바와 같이, 중앙에 팬모터(3)를 취부하기 위해 원형의 구멍으로 된 모터체결부(2a)가 형성되고, 모터체결부(2a)외주면에 동일한 각도(120°)로 배치되고 외측 단부가 각기 쉬라우드(1)쪽으로 절곡연장되는 지지축(2b)이 연결되며, 각 지지축(2b) 끝에 구멍이 형성되는 고정부(2c)가 형성되어 있다.Here, as shown in FIG. 2, the bracket 2 is provided with a motor fastening portion 2a formed of a circular hole in the center for mounting the fan motor 3, and is provided on the outer circumferential surface of the motor fastening portion 2a. Support shafts 2b are arranged at the same angle (120 °) and the outer ends are bent toward the shroud 1, respectively, and a fixing portion 2c is formed in which holes are formed at the ends of the support shafts 2b. have.
이러한 브라켓(2)은 모터체결부(2a)에 팬모터(3)의 외주면이 삽입되어 고정되고, 지지축(2b)끝의 고정부(2c)와 쉬라우드(1)사이에 방진구(5)가 삽입되며, 고정부(2c)의 구멍을 통해 나사가 방진구(5)를 관통하여 쉬라우드(1)에 고정된다.The bracket 2 is fixed by inserting the outer circumferential surface of the fan motor 3 into the motor fastening portion 2a and between the fixing portion 2c at the end of the support shaft 2b and the shroud 1. ) Is inserted, and the screw penetrates the dustproof opening 5 through the hole of the fixing portion 2c and is fixed to the shroud 1.
이와같이 구성되는 종래 에어콘 실외기의 송풍팬 지지구조는 브라켓(2)에 의해 팬모터(3)가 지지되고, 팬모터(3)에 의해 송풍팬(3)이 회전되어 쉬라우드(1)의 송풍구멍을 통해 외부의 공기가 실외기의 열교환기방향으로 송풍된다. 또한, 송풍팬(4)은 날개가 등간격으로 배열되어 있어, 유체가 통과할 때 날개 사이의 유동속도가 서로 다름으로 인해서 주기적인 진동이 발생되는데, 팬모터(3)를 지지하는 브라켓(2)과 쉬라우드(1)사이에 삽입되는 방지구(5)는 송풍팬(4)이 회전될 때 생기는 진동을 흡수하게 된다.The blower fan supporting structure of the conventional air conditioner outdoor unit configured as described above is supported by the fan motor 3 by the bracket 2, and by the fan motor 3, the blower fan 3 is rotated so that the blowing hole of the shroud 1 is provided. Through the outside air is blown toward the heat exchanger of the outdoor unit. In addition, the blower fan 4 has the wings are arranged at equal intervals, the periodic vibration is generated due to the different flow speed between the blades when the fluid passes, the bracket (2) for supporting the fan motor (3) And the prevention tool 5 inserted between the shroud 1 absorbs vibration generated when the blowing fan 4 is rotated.
그러나, 이러한 종래 에어콘 실외기의 송풍팬 지지구조는 송풍팬(4)의 날개에서 발생되는 진동이 방진구(5)에서 흡수됨에도 불구하고, 제4도의 그래프에서 굵은선(A)이 나타내는 바와 같이, 송풍팬(4)의 진동으로 인한 상당한 소음이 발생되었다.However, the blower fan supporting structure of the conventional air conditioner outdoor unit has a thick line A in the graph of FIG. 4, even though the vibration generated in the blades of the blower fan 4 is absorbed by the dustproof port 5, Significant noise was generated due to the vibration of the blower fan 4.
본 고안의 목적은 상기와 같이 종래 송풍팬에서 발생되는 소음을 저감시켜 주기 위하여, 팬모터를 지지하는 브라켓 지지축의 배치각도를 비 등간격으로 형성하는 에어콘 실외기의 송풍팬 지지구조를 제공하는데 있다.It is an object of the present invention to provide a blower fan support structure of an air conditioner outdoor unit to form an arrangement angle of the bracket support shaft for supporting a fan motor at a uniform interval in order to reduce the noise generated in the conventional blower fan as described above.
이하 첨부된 도면에 따라 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.
제3도는 본 고안의 브라켓을 나타내는 평면도이고, 제4도는 종래 브라켓과 본 고안 브라켓의 체결후 소음실험 결과를 비교 도시한 그래프이다.3 is a plan view showing a bracket of the present invention, Figure 4 is a graph showing a comparison of the noise test results after the conventional bracket and the bracket of the present invention.
본 고안의 브라켓(10)도 중앙에 팬모터를 취부하기 위해 원형의 구멍으로 된 모터체결부(11)가 형성되고, 모터체결부(2a)외주면에 쉬라우드쪽으로 지지축(12)들이 연장되며, 각 지지축(12)의 끝에 구멍이 형성되는 고정부(13)가 형성되는 것은 종래와 같다. 단, 본 고안의 모터체결부(11)에 연결되는 지지축(12)이 모터체결부(11)의 외주면에 비 등간격으로 배치됨을 그 기술적 구성상의 특징으로 한다.In the bracket 10 of the present invention, a motor fastening portion 11 having a circular hole is formed to mount a fan motor in the center thereof, and support shafts 12 are extended toward the shroud on the outer circumferential surface of the motor fastening portion 2a. , The fixing portion 13 is formed in the end of each of the support shaft 12 is formed as in the prior art. However, a technical feature of the technical configuration is that the support shaft 12 connected to the motor fastening part 11 of the present invention is disposed at equal intervals on the outer circumferential surface of the motor fastening part 11.
또한, 제3도에서 도시되는 브라켓(10)은 상부와 하부의 지지축(12)이 180°간격으로 배치되고,측부의 지지축(12)이 하부의 지지축(12)에 60°간격으로 배치된다.In addition, in the bracket 10 shown in FIG. 3, the upper and lower support shafts 12 are disposed at 180 ° intervals, and the support shafts 12 at the side are spaced at 60 ° intervals from the lower support shaft 12. Is placed.
한편, 본고안의 송풍팬 지지구조도 브라켓(10)의 모터체결부(11)에 팬모터의 외주면이 삽입되어 고정되고, 지지축(12)끝의 고정부(13)와 쉬라우드 사이에 방진구가 삽입되며, 고정부(13)의 구멍을 통해 나사가 방진구를 관통하여 쉬라우드에 고정된다.On the other hand, the blowing fan support structure of the present invention is also fixed to the motor fastening portion 11 of the bracket 10 by inserting the outer peripheral surface of the fan motor, between the fixing portion 13 of the end of the support shaft 12 and the shroud Is inserted into the screw through the hole of the fixing portion 13 is fixed to the shroud.
이와같이 구성되는 본 고안은 유체가 송풍팬을 통과할 때 날개 사이의 유동속도가 서로 다름으로 인해서 주기적으로 발생되는 진동이, 비 등간격으로 지지축(12)이 배치되어 팬모터를 지지하는 브라켓(10)에 의해 흡수되어 소음이 저감되게 된다.The present invention constituted as described above has a bracket in which vibrations periodically generated due to different flow speeds between the blades when the fluid passes through the blower fan are arranged at equal intervals to support the fan motor ( 10) is absorbed by the noise is reduced.
이러한 본 고안은 송풍팬의 진동을 브라켓(10)이 저감시켜 주므로, 제4도의 그래프에서 가는선(B)이 나타내는 바와 같이, 진동으로 인해 발생되는 소음이 전 주파수 영역에서 현저하게 줄어듬을 볼 수 있다.Since the present invention reduces the vibration of the blower fan by the bracket 10, as shown by the thin line B in the graph of FIG. 4, the noise generated by the vibration can be seen to be significantly reduced in the entire frequency range. have.
이상에서 살펴본 바와 같이, 본 고안은 팬모터를 지지하는 브라켓의 지지축 배치 각도를 비 등간격으로 형성하여, 진동으로 인한 소음을 저감시켜 주는 매우 유용한 것이다.As described above, the present invention is very useful to reduce the noise due to vibration by forming the support shaft arrangement angle of the bracket for supporting the fan motor at an equal interval.
