Description

공기조화기의 풍향조절장치{AIR DIRECTION CONTROL DEVICE OF AIR CONDITIONER}Air direction control device of air conditioner {AIR DIRECTION CONTROL DEVICE OF AIR CONDITIONER}

본 발명은 공기조화기의 풍향조절장치에 관한 것으로, 더욱 상세하게는 하나의 모터를 이용하여 다수 개의 베인이 각기 다른 각도로 회전되도록 한 공기조화기의 풍향조절장치에 관한 것이다.The present invention relates to a wind direction control device for an air conditioner, and more particularly, to a wind direction control device for a plurality of vanes are rotated at different angles using one motor.

일반적으로 공기조화기는 실내공간을 쾌적한 상태로 유지하기 위하여 실내공기를 조화시키는 장치로, 흡입구 및 토출구를 구비하는 본체를 구비한다.In general, the air conditioner is a device that harmonizes the indoor air in order to maintain the indoor space in a comfortable state, and has a main body having an inlet and an outlet.

본체 내부에는 흡입구를 통해 본체 내부로 유입된 공기를 열교환시키는 열교환기와, 실내공기를 흡입함은 물론 열교환된 공기를 토출구 측으로 송풍시키는 송풍팬이 마련된다.Inside the main body, a heat exchanger for heat-exchanging air introduced into the main body through an intake port, and a blower fan that sucks indoor air and blows heat-exchanged air to the discharge port side are provided.

또 토출구 측에는 토출구를 통해 실내공간으로 토출되는 공기의 풍향을 조절하도록 풍향조절장치가 마련된다. 이러한 풍향조절장치는 토출구에 회전가능하도록 설치되는 다수개의 베인과, 각 베인을 연결시키는 링크와, 일측 베인의 회전중심이 결합되는 캠과, 캠을 구동시키기 위한 구동모터를 구비한다.In addition, the wind direction control device is provided on the discharge port side to adjust the wind direction of the air discharged to the indoor space through the discharge port. The wind direction control device includes a plurality of vanes rotatably installed at the discharge port, a link connecting each vane, a cam to which the rotation center of one vane is coupled, and a driving motor for driving the cam.

따라서 구동모터를 구동시켜 캠을 회전시키면, 캠과 연결된 일측 베인이 회전됨과 동시에 이 베인과 링크로 연결된 나머지 베인들도 동일한 회전각도를 이루며 회전하게 되고, 토출공기의 풍향은 이러한 베인의 회전각도 따라 변화하게 된다.Therefore, when the cam is rotated by driving the driving motor, one vane connected to the cam is rotated, and the other vanes connected to the vane and the link are rotated at the same rotation angle, and the wind direction of the discharged air depends on the rotation angle of the vane. Will change.

그러나 이러한 종래 공기조화기의 풍향조절장치는 상술한 바와 같이 다수개의 베인이 모두 동일한 회전각도를 이루며 회전하도록 마련되기 때문에, 송풍팬의 회전형태에 따라 토출구의 위치별로 각기 다른 풍향 및 풍량이 요구되어 각 베인을 각기 다른 각도로 회전시키고자 할 경우 이를 만족시키지 못하는 문제점을 가지고있다.However, since the conventional air conditioner of the air conditioner is provided to rotate the plurality of vanes to form the same rotation angle as described above, different wind direction and the amount of air is required for each position of the discharge port according to the rotation type of the blowing fan. If you want to rotate each vane at a different angle has a problem that does not satisfy this.

물론 각각의 베인에 별도의 구동모터를 설치하면 각 베인의 회전각도를 다르게 조절할 수도 있으나, 이러한 경우에는 다수개의 구동모터 마련에 따른 비용상승 문제가 발생한다.Of course, if a separate drive motor is installed on each vane, the angle of rotation of each vane may be adjusted differently, but in this case, a cost increase problem occurs due to the provision of a plurality of drive motors.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 하나의 모터를 이용하여 다수 개의 베인이 각기 다른 각도로 회전되도록 한 공기조화기의 풍향조절장치를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to provide a wind direction control device for a plurality of vanes are rotated at different angles by using a single motor.

참고적으로, 도 1은 베인이 회전되기 전의 상태를 보인 것이며, 도 2는 베인이 회전된 상태를 나타낸 것이다.For reference, FIG. 1 shows a state before the vane is rotated, and FIG. 2 shows a state in which the vane is rotated.

도 1과 같이 구동모터(30)가 회전되기 전 각 베인(10,20)은 토출구(1)를 폐쇄한 상태를 유지한다. 이 상태에서 도 2에 도시된 바와 같이, 구동모터(30)를 일방향으로 구동시키면, 구동모터(30)의 회전축(미도시)이 회전하며 이에 결합된 구동베인(10)이 회전중심(12)을 축으로 소정각도 회전한다. 그리고 이러한 구동베인(10)의 회전은 상기 제1링크축(41)를 구동베인(10)과 같은 방향으로 회전시키면서 상기 굴절축(60)을 캠홈(71)을 따라 이동시키며, 이러한 굴절축(60)의 이동에 의해 제2링크(50)에 형성된 제2링크축(51)이 이동되면서 종동베인(20) 역시 회전중심(22)을 축으로 회전하게 된다. 그런데 이때 상기 구동베인(10)은 구동모터(30)의 회전에 의해서만 그 회전각이 조절되는데 반해, 상기 종동베인(20)은 캠홈(71)을 따라 이동하는 굴절축(60)에 의해 그 회전각이 조절되므로, 각 베인(10,20)은 서로 다른 회전각을 갖도록 회전하게 된다.As shown in FIG. 1, each vane 10 and 20 maintains the discharge port 1 closed before the driving motor 30 is rotated. In this state, as shown in FIG. 2, when the driving motor 30 is driven in one direction, a rotating shaft (not shown) of the driving motor 30 rotates and the driving vane 10 coupled thereto rotates the center of rotation 12. Rotate a predetermined angle around the axis. The rotation of the driving vane 10 moves the refractive shaft 60 along the cam groove 71 while rotating the first link shaft 41 in the same direction as the driving vane 10. As the second link shaft 51 formed on the second link 50 is moved by the movement of 60, the driven vane 20 also rotates the rotation center 22 about the axis. By the way, the driving vane 10 is the rotation angle is adjusted only by the rotation of the drive motor 30, the driven vane 20 is rotated by the refraction shaft 60 moving along the cam groove 71 Since the angle is adjusted, each vane 10, 20 is rotated to have a different rotation angle.

이와 같이 본 발명에 따른 공기조화기의 풍향조절장치는 구동베인(10)의 회전에 따라 상기 종동베인(20)이 구동베인(10)과 다른 회전각도로 회전하도록 구성됨으로써, 토출구(1)의 위치별로 각기 다른 풍향 및 풍량이 요구될 경우 유용하게 사용될 수 있다. 또한, 이러한 풍향조절장치는 하나의 구동모터(30)만을 이용하여 구동베인(10)과 종동베인(20)이 각기 다른 각으로 회전할 수 있도록 함으로써 구동모터(30) 수를 절감시키는 효과도 갖는다.As such, the wind direction control apparatus of the air conditioner according to the present invention is configured to rotate the driven vane 20 at a different rotation angle from the driving vane 10 according to the rotation of the driving vane 10, thereby It can be useful when different wind direction and air volume are required for each location. In addition, the wind direction control device also has the effect of reducing the number of drive motor 30 by allowing the drive vanes 10 and driven vanes 20 to rotate at different angles using only one drive motor 30. .

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 공기조화기의 풍향조절장치는 굴절축 및 캠홈을 포함하도록 구성되어 하나의 모터를 이용하여 다수 개의 베인이 각기 다른 각도로 회전되도록 하는 이점을 갖는다.As described in detail above, the wind direction control device of the air conditioner according to the present invention is configured to include a refraction axis and a cam groove has the advantage that a plurality of vanes are rotated at different angles by using a single motor.
