일반적으로 창문형 공조기는 건물의 벽 또는 창문 틀을 통해 밀폐된 공조장소측과 실외에 걸쳐 설치하여 공조장소 내의 공기를 강제적으로 순환시켜 공조장소를 소정의 온도대로 공조시킨다. 이때 공조장소는 밀폐된 공간으로 장시간 공조시 공기가 탁해져 환기가 요구된다. 따라서 창문형 공조기에는 필수적으로 환기장치를 구비하고 있다.In general, the window type air conditioner is installed over the air conditioning side and the outside of the airtight place through the wall or window frame of the building to force circulation of the air in the air place to the air conditioning place at a predetermined temperature. At this time, the air conditioning place is enclosed space and air is clouded when air-conditioning for a long time requires ventilation. Therefore, the window air conditioner is essentially equipped with a ventilation device.

도 1은 종래 기술에 의한 창문형 공조기의 내부 구성을 나타낸 평면도이다.1 is a plan view showing the internal configuration of a window type air conditioner according to the prior art.

도 1에서 종래 기술에 의한 창문형 공조기는 일측면에 환기구(22)를 형성한 칸막이(20)로 몸체(10) 내부를 구획하여, 칸막이(20) 후방에 소음원이 되는 압축기, 응축기, 실외팬 등을 내장하여 실외에 위치하도록 하고, 칸막이(20) 전방에 열교환기(30), 실내팬(40) 등을 내장하여 실내에 위치하도록 하며, 환기구(22)에 출몰하여 환기정도를 조절하기 위한 개폐수단을 장착하여 이루어진다.In FIG. 1, the window type air conditioner according to the related art divides the inside of the body 10 into a partition 20 having a ventilation opening 22 formed on one side thereof, such as a compressor, a condenser, an outdoor fan, and the like as a noise source behind the partition 20. To be located outdoors, the partition 20 in front of the heat exchanger 30, the indoor fan 40, and the like to be located in the room, and the opening and closing to adjust the degree of ventilation by appearing in the ventilation opening (22) Made by mounting means.

상기 개폐수단은 실내외 공기의 유로(52)를 형성하여 환기구(22)를 차단하는 댐퍼(54); 상기 댐퍼(54)를 일측에 형성하고, 타측에 손잡이(56)를 형성하며, 토출구(70) 저면에 나사(60) 체결하여 나사(60)를 축으로 몸체(10) 외부에서 전후진 작동하는 조절레버(50)로 이루어진다.The opening and closing means includes a damper 54 for blocking the ventilation opening 22 by forming a flow path 52 of indoor and outdoor air; The damper 54 is formed on one side, and the handle 56 is formed on the other side, and the screw 60 is fastened to the bottom surface of the discharge port 70 so that the screw 60 is driven forward and backward from the outside of the body 10. The control lever 50 is made.

상기 구성에 의한 종래의 창문형 공조기는 실내팬(40)의 회전에 의하여 공조장소의 공기를 몸체(10) 내부로 흡입하여 열교환기(30)를 통과시켜 소정의 온도대로 열교환을 이룬다. 이후 열교환된 공조공기를 토출구(70)를 통하여 공조장소측으로 과급시키면서 공조장소를 소기의 온도대로 공조시킨다. 이때 공조장소는 밀폐된 공간으로 인해 일정시간 공조시 공기가 탁해진다. 이에 공조장소의 탁한 공기가 실외의 신선한 공기를 교환시켜, 공조장소를 소정의 온도대로 유지함과 동시에 쾌적한 공간을 유지하기 위하여 개폐수단을 조절한다. 이러한 개폐수단의 조절은 토출구(70)측으로 돌출하여 몸체(10) 외부에 위치한 손잡이(64)를 전진 작동하면, 조절레버(50)가 나사(60)를 축으로 후진함과 동시에 댐퍼(54)의 유로(52)가 개로 된다. 이에 댐퍼(54)의 유로(52)를 통해 공조장소의 환기가 이루어진다.The conventional window type air conditioner according to the above configuration sucks air in the air conditioning place into the body 10 by the rotation of the indoor fan 40 and passes through the heat exchanger 30 to achieve heat exchange at a predetermined temperature. Then, the air-conditioning place is air-conditioned at the desired temperature while superheating the heat-exchanged air-conditioning air through the discharge port 70.
