또한, 상기 다수의 딤플은 상기 풍향조절날개의 양면에 각각 마련된다.In addition, the plurality of dimples are provided on both sides of the wind direction control blade.

이하에서는 본 발명의 바람직한 하나의 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment of the present invention will be described in detail with reference to the drawings.

본 발명에 따른 공기조화기 실내기는 도 1에 도시한 바와 같이, 전면 상부에 사각의 토출구(11)가 형성되고 전면 하부에 흡입구(12)가 형성된 상자형의 캐비닛(10)을 구비한다.As shown in FIG. 1, the indoor unit of the air conditioner according to the present invention includes a box-shaped cabinet 10 in which a rectangular discharge port 11 is formed at an upper front side and an inlet 12 is formed at a lower front side.

캐비닛(10) 내에는 흡입구(12)를 통해 유입된 공기와 열교환하는 증발기(13)와, 공기가 흡입구(12)를 통해 유입되어 증발기(13)와 열교환하여 냉각된 후 토출구(11)를 통해 배출되게 하는 송풍팬(14)과, 송풍팬(14)을 회전시키는 구동모터(15)가 구비되어 있다. 따라서 공기조화기 실내기에 전원이 인가되면 송풍팬(14)이 회전하면서 전면 하부에 마련된 흡입구(12)을 통해 공기를 흡입하여 증발기(13)와 열교환되게 한 후, 전면 상부에 마련된 토출구(11)를 통해 토출되게 하는 것이다.In the cabinet 10, an evaporator 13 for exchanging heat with air introduced through the inlet 12, and air is introduced through the inlet 12, cooled by heat exchange with the evaporator 13, and then discharged through the outlet 11. A blowing fan 14 for discharging and a driving motor 15 for rotating the blowing fan 14 are provided. Therefore, when power is applied to the indoor unit of the air conditioner, the blower fan 14 rotates to suck air through the inlet 12 provided at the lower front thereof to exchange heat with the evaporator 13, and then the outlet 11 provided at the upper front side. It is to be discharged through.

한편 토출구(11)에는 도 2에 도시한 바와 같이 토출구(11)를 통해 토출되는 공기의 풍향을 조절하여 실내공간이 골고루 냉각될 수 있게 하는 풍향조절날개(20)가 구비된다.On the other hand, the discharge port 11 is provided with a wind direction control blade 20 to adjust the wind direction of the air discharged through the discharge port 11, as shown in FIG.

풍향조절날개(20)는 토출구(11)에 좌우방향으로 길게 설치되며 양 끝단이 토출구(11)의 양측에 힌지 결합되어 상하로 회동하며 토출되는 공기의 풍향을 상하로 조절하는 다수의 수평풍향조절날개(21)와, 토출구(11)에 상하방향으로 길게 설치되며 양 끝단이 토출구(11)의 상하측에 힌지결합되어 좌우로 회동하며 토출되는 공기의 풍향을 좌우로 조절하는 수직풍향조절날개(22)로 이루어져 토출되는 공기의 풍향을 상하좌우로 조절할 수 있다.Wind direction control blade 20 is installed in the discharge port 11 in the left and right direction long and a plurality of horizontal wind direction control to adjust the wind direction of the discharged air up and down by rotating both ends are coupled to both sides of the discharge port 11 up and down Vertical wind direction control blades installed in the wing 21 and the discharge port 11 in the vertical direction long and both ends are hinged to the upper and lower sides of the discharge port 11 to rotate left and right to adjust the air direction of the discharged air from side to side ( 22) the air direction of the discharged air can be adjusted up, down, left and right.

한편, 토출구(11)의 양측에는 다수의 힌지공(17)이 마련된 제 1 날개설치부재(16a)가 대향되게 설치되어 수평풍향조절날개(21)를 설치할 수 있도록 되어 있으며, 토출구(11)의 상하측에는 다수의 힌지공(17)이 마련된 제 2 날개설치부재(16b)가 대향되게 설치되어 다수의 수직풍향조절날개(22)를 설치할 수 있도록 되어 있다.On the other hand, on both sides of the discharge port 11, the first wing installation member 16a provided with a plurality of hinge holes 17 is installed to face the horizontal wind direction control blade 21, so that the discharge port 11 The upper and lower sides of the second wing installation member 16b provided with a plurality of hinge holes 17 are installed to face each other so that a plurality of vertical wind direction control blades 22 may be installed.

이러한 공기조화기 실내기에 있어서, 토출구(11)를 통해 공기가 토출될 때,공기는 풍향조절날개(20)의 전단측에서 박리현상을 일으키게 되어 풍향조절날개(20)의 전방측은 상대적으로 저압상태가 되고 이러한 저압부가 공기의 흐름을 방해하여 토출되는 공기의 풍속을 감속시키는 형상저항으로써 작용한다.In the indoor unit of the air conditioner, when the air is discharged through the discharge port 11, the air is peeled off at the front end of the wind direction control blade 20, so that the front side of the wind direction control blade 20 is in a relatively low pressure state. These low pressure portions interfere with the flow of air and act as shape resistance to slow down the wind speed of the discharged air.

따라서, 본 발명에 따른 공기조화기 실내기의 수평풍향조절날개(21)에는 도 3, 4에 도시한 바와 같이 다수의 딤플(23:dimple)이 마련된다. 딤플(23)은 수평풍향조절날개(21)의 양면에 반구형상으로 오목하게 마련되어 수평풍향조절날개(21)에 의해 안내되며 토출되는 공기가 난류유동하게 하는 것으로, 공기가 난류유동하며 저압부에 공급되게 함으로써, 수평풍향조절날개(21)의 전단측에서 발생하는 박리현상을 방지할 수 있게 된다. 그러므로 풍향조절날개(20)의 형상에 의해 발생하는 형상저항이 감소되어 공기의 유동이 원활하게 이루어질 수 있게 된다.Therefore, the horizontal wind direction control blade 21 of the indoor unit of the air conditioner according to the present invention is provided with a plurality of dimples 23 (dimple), as shown in FIGS. The dimple 23 is concave in a hemispherical shape on both sides of the horizontal wind direction control blade 21, guided by the horizontal wind direction control blade 21, and the discharged air is turbulent flow, the air is turbulent flow and low pressure portion By being supplied, it is possible to prevent the peeling phenomenon occurring at the front end side of the horizontal wind direction control blade 21. Therefore, the shape resistance generated by the shape of the wind direction control vane 20 is reduced to facilitate the flow of air.

본 실시예에서는 딤플(23)이 수평풍향조절날개(21)에 형성되어 있는 것을 예로써 설명하였으나, 이에 한정하지 않고 도 5에 도시한 바와 같이 수직풍향조절날개(22)에 딤플(23)을 형성하는 등의 구성도 가능하다.In the present embodiment, the dimple 23 is formed in the horizontal wind direction control blade 21 by way of example, but the present invention is not limited thereto, and the dimple 23 is disposed on the vertical wind direction control blade 22 as shown in FIG. 5. It may also be configured.

또한, 본 실시예에서는 패키지형 공기조화기 실내기에 적용된 풍향조절날개(20)를 예로써 제시하였으나, 이에 한정하지 않고 벽걸이형 공기조화기 실내기에 마련된 풍향조절날개나 창문형 공기조화기에 마련된 풍향조절날개에도 동일하게 적용되어질 수 있다.In addition, in the present embodiment, the wind direction control wing 20 applied to the packaged air conditioner indoor unit is provided as an example, but the present invention is not limited thereto. The wind direction control wing provided in the wall-mounted air conditioner indoor unit or the window type air conditioner is provided. The same can be applied to.

또한, 본 실시예에서 딤플(23)은 반구형상으로 오목하게 형성되어 있으나, 필요에 따라 다양한 형상 및 크기로 형성할 수 있다.In addition, in the present embodiment, the dimple 23 is concave in a hemispherical shape, but may be formed in various shapes and sizes as necessary.

다음은 이와 같이 구성된 본 발명에 따른 공기조화기의 동작 및 작용효과를도면을 참조하여 상세히 설명한다.Next will be described in detail with reference to the drawings the operation and effect of the air conditioner according to the present invention configured as described above.

공기조화기 실내기에 전원이 인가되어 구동모터(15)에 의해 송풍팬(14)이 회전하면, 송풍팬(14)의 송풍력에 의해 흡입구(12)를 통해 실내공기가 캐비닛(10) 내로 흡입되고, 흡입된 공기가 증발기(13)와 열교환한 후 토출구(11)를 통해 토출되어 실내공간을 냉각한다.When power is supplied to the indoor unit of the air conditioner and the blowing fan 14 is rotated by the driving motor 15, the indoor air is sucked into the cabinet 10 through the inlet 12 by the blowing force of the blowing fan 14. Then, the sucked air is heat-exchanged with the evaporator 13 and then discharged through the discharge port 11 to cool the indoor space.

이 때, 토출되는 공기는 토출구(11)에 마련된 수평풍향조절날개(21)에 의해 상하로 풍향이 조절되는데, 수평풍향조절날개(21)에 접하는 공기는 수평풍향조절날개(21)에 마련된 딤플(23)에 의해 난류유동하며 수평풍향조절날개(21)의 전단측 저압부에 공급된다. 따라서, 수평풍향조절날개(21)의 전단측에서 박리현상 및 그에 따른 압력저하 현상이 발생하지 않아 형상저항이 감소되고, 그에 따라, 토출구(11)로부터 수평풍향조절날개(20)에 의해 안내되어 토출되는 공기의 풍속 감소가 저감된다.At this time, the discharged air is controlled up and down by the horizontal wind direction control blade 21 provided in the discharge port 11, the air in contact with the horizontal wind direction control blade 21 is a dimple provided in the horizontal wind direction control blade (21). Turbulent flow by 23 is supplied to the low pressure side of the front side of the horizontal direction control blade (21). Therefore, the peeling phenomenon and the pressure drop phenomenon do not occur at the front end side of the horizontal wind direction control blade 21, so that the shape resistance is reduced, and thus is guided by the horizontal wind direction control wing 20 from the discharge port 11. The wind speed reduction of the discharged air is reduced.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 공기조화기 실내기는 토출구를 통해 배출되는 공기의 풍향을 조절하는 풍향조절날개에 다수의 딤플이 마련되어 토출공을 통해 배출되는 공기가 난류유동하게 함으로써, 풍향조절날개의 형상저항을 감소시켜 토출되는 공기의 풍속 감소를 저감할 수 있게 되는 작용효과가 있다.As described in detail above, the air conditioner indoor unit according to the present invention is provided with a plurality of dimples on the wind direction control vanes for adjusting the wind direction of the air discharged through the discharge port, so that the air discharged through the discharge hole turbulent flow, The effect of reducing the wind resistance of the discharged air by reducing the shape resistance of the control blade is effective.
