본 발명은 공기조화기에 관한 것으로, 더욱 상세하게는 와류발생의 억제를 통해 공기의 송풍효율이 향상될 수 있도록 하는 공기조화기에 관한 것이다.The present invention relates to an air conditioner, and more particularly, to an air conditioner for improving the blowing efficiency of air through suppression of vortex generation.

일반적인 공기조화기의 실내기는 본체의 내부에 실내공기의 순환을 위한 송풍팬과, 본체 내부로 순환하는 공기의 열교환을 위한 열교환기를 구비한다. 또한 공기조화기의 실내기 중에는 송풍능력과 동작의 정숙성 등을 감안하여 송풍팬을 통상의 횡류팬으로 채용하는 것이 많으며, 큰 송풍능력을 위해 복수의 횡류팬을 채용하는 것도 있다.An indoor unit of a general air conditioner includes a blower fan for circulating indoor air inside a main body, and a heat exchanger for heat exchange of air circulating into the main body. In addition, in the indoor unit of the air conditioner, a blower fan is generally adopted as a conventional crossflow fan in consideration of blowing ability and quietness of operation, and a plurality of crossflow fans are adopted for large blowing ability.

복수의 횡류팬을 채용하는 실내기는 도 1에 도시한 바와 같이, 본체(1)의 전면에 흡입구(2)가 형성되고, 본체(10)의 양쪽 측방에 토출구(3)가 형성되며, 흡입구(2)와 인접하는 본체(1)의 내부에 실내공기의 열교환을 위한 열교환기(4)가 설치된다. 또 토출구(3)와 인접하는 열교환기(4)의 후방 양측에는 실내공기의 강제송풍을 위한 것으로 두 횡류팬(5a,5b)이 각각 설치된다. 이러한 실내기는 두 횡류팬(5a,5b)이 동시에 동작할 때 본체(1) 전면의 흡입구(2)를 통해 흡입된 실내공기가 열교환기(4)를 통과하면서 열교환 된 후, 양측의 두 횡류팬(5a,5b)을 통해 토출구(3) 쪽으로 송풍되어 다시 실내공간으로 공급될 수 있도록 한 것이다.As shown in FIG. 1, an indoor unit employing a plurality of crossflow fans has a suction port 2 formed on the front surface of the main body 1, a discharge port 3 formed on both sides of the main body 10, and a suction port ( A heat exchanger 4 is installed inside the main body 1 adjacent to 2) for heat exchange of indoor air. In addition, two cross flow fans 5a and 5b are provided on both sides of the rear side of the heat exchanger 4 adjacent to the discharge port 3 for the forced air of the indoor air.

The discharge blade 19 is provided in a size substantially corresponding to the length and width of the discharge port 14 so that the discharge port 14 can be closed when the air conditioner is stopped, the main body case 10 on one side of the discharge port 14 Rotatingly coupled to the inner surface is configured to rotate in the forward or reverse direction by the operation of a motor (not shown) so that the discharge air is distributed to the indoor space. In addition, the air guide plate 20 extending to the outer surface of the two cross flow fan (17, 18) so that the blowing air toward the discharge port 14 is made when the two cross flow fan (17, 18) operates on both sides of the discharge port (14). ) Is provided.

이러한 공기조화기는 양측의 두 횡류팬(17,18)이 동작할 때 본체(10) 전면의 흡입구(13)를 통해 본체(10)의 내부로 흡입되는 실내공기가 열교환기(16)를 통과하면서 냉기 또는 온기가 되며, 이러한 공기가 양측의 두 횡류팬(17,18) 쪽으로 유동하여 토출구(14)를 통해 다시 실내공간으로 공급되도록 함으로써 실내공간의 냉방 또는 난방을 수행한다.The air conditioner passes through the heat exchanger 16 while indoor air sucked into the inside of the main body 10 through the inlet 13 in front of the main body 10 when the two cross flow fans 17 and 18 of both sides operate. Cooling or warming, the air flows toward the two cross flow fans (17, 18) on both sides to be supplied back to the interior space through the discharge port 14 to perform the cooling or heating of the indoor space.

또한 본 발명에 따른 공기조화기의 두 횡류팬(17,18) 사이에는 상술한 바와 같은 공기의 순환이 이루어질 때 두 횡류팬(17,18) 사이의 공간에서 와류가 생기지 않도록 하기 위해 본체(10)의 내측 후면으로부터 열교환기(16) 쪽으로 돌출하도록 형성되는 와류방지부재(30)가 마련된다. 이 와류방지부재(30)는 도 2에 도시한 바와 같이, 두 횡류팬(17,18)과 평행하도록 두 횡류팬(17,18)의 길이방향으로 길게 연장된다. 또 와류방지부재(30)는 본체(10)와 일체로 형성될 수 도 있고, 도 3에 도시한 바와 같이, 수지재 등을 통해 별도로 제작된 후 본체(10)의 후면부 내측에 장착될 수 도 있다.In addition, between the two crossflow fans 17 and 18 of the air conditioner according to the present invention, the main body 10 to prevent vortices from occurring in the space between the two cross flow fans 17 and 18 when the air is circulated as described above. Vortex prevention member 30 is formed to protrude toward the heat exchanger 16 from the inner rear of the). As shown in FIG. 2, the vortex preventing member 30 extends in the longitudinal direction of the two crossflow fans 17 and 18 so as to be parallel to the two crossflow fans 17 and 18. In addition, the vortex preventing member 30 may be integrally formed with the main body 10, and as shown in FIG. 3, may be mounted inside the rear part of the main body 10 after being separately manufactured using a resin material or the like. have.

이러한 와류방지부재(30)의 구성은 종래 와류가 발생하던 두 횡류팬(17,18) 사이의 공간을 와류방지부재(30)가 점유하도록 함으로써 공기의 유동과정에서 와류가 생기지 않도록 한 것이며, 이를 통해 공기의 송풍효율이 향상되고 유동소음이 줄어들 수 있도록 한 것이다.The configuration of the vortex preventing member 30 is to prevent vortices in the air flow process by allowing the vortex preventing member 30 to occupy the space between the two crossflow fans 17 and 18 where the vortex is conventionally generated. Through this, air blowing efficiency is improved and flow noise is reduced.

이러한 와류방지부재(30)를 장착한 공기조화기를 실험한 결과, 송풍효율을 높이고 소음을 줄일 수 있도록 하기 위해서는 본체(10)의 후방 내면으로부터 돌출되는 와류방지부재(30)의 돌출높이(H)가 본체(10)의 후방 내면으로부터 열교환기(16)까지 거리(L)의 30 ~ 70%에 해당하도록 하도록 할 때 가장 좋은 성능을 발휘할 수 있었다. 즉 도 4에 도시한 바와 같이, 와류방지부재(30)의 높이(H)를 낮게 할 때는 토출유량이 많은 반면에 소음이 큰 문제가 있었고, 와류방지부재(30)가 열교환기(16)에 근접하도록 높이(H)를 높일 때는 유량이 작아지고 소음이 큰 문제가 있었다. 그리고 와류방지부재(30)의 높이(H)가 본체(10) 내면으로부터 열교환기(16)까지 거리(L)의 30% ~ 70%에 이르는 범위에서는 유량도 좋고 소음감소효과 또한 좋은 특성을 보였다. 특히 이러한 와류방지부재(30)는 도 3에 도시한 바와 같이, 전면패널(13a) 사방둘레의 이격된 공간을 통해 실내공기가 흡입되는 형태의 공기조화기의 경우 송풍효율과 소음감소에서 더욱 우수한 효과를 발휘하였다.As a result of experimenting with the air conditioner equipped with the vortex preventing member 30, in order to increase the blowing efficiency and reduce the noise, the protrusion height H of the vortex preventing member 30 protruding from the rear inner surface of the main body 10 is measured. The best performance could be exhibited so as to correspond to 30 to 70% of the distance L from the rear inner surface of the main body 10 to the heat exchanger 16. That is, as shown in Figure 4, when lowering the height (H) of the vortex preventing member 30, while the discharge flow rate is large, there was a large noise problem, the vortex preventing member 30 to the heat exchanger (16) When increasing the height (H) to approach, there was a problem that the flow rate is small and the noise is large. In addition, the flow rate of the vortex preventing member 30 ranged from 30% to 70% of the distance L from the inner surface of the main body 10 to the heat exchanger 16 showed good flow rate and noise reduction effect. . In particular, as shown in FIG. 3, the vortex preventing member 30 is more excellent in blowing efficiency and noise reduction in the case of an air conditioner in which indoor air is sucked through spaced spaces around the front panel 13a. It worked.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 공기조화기는 두 횡류팬 사이의 본체 내면으로부터 열교환기 쪽으로 돌출하도록 마련되는 와류방지부재에 의해 와류의 발생이 억제되기 때문에, 송풍효율이 향상되고 공기의 유동소음이 감소하는 효과가 있다.As described above in detail, the air conditioner according to the present invention is suppressed by the vortex prevention member provided to protrude toward the heat exchanger from the inner surface of the main body between the two transverse fans, the blowing efficiency is improved and the flow of air Noise is reduced.
