본 발명은 에어컨 열교환기의 응축수 제거장치에 관한 것으로, 특히 열교환기에 발생되는 응축수를 제거하여 에너지 효율을 향상시키도록 하는데 적합한 에어컨 열교환기의 응축수 제거장치에 관한 것이다.The present invention relates to a condensate removal device for an air conditioner heat exchanger, and more particularly to a condensate removal device for an air conditioner heat exchanger suitable for removing the condensate generated in the heat exchanger to improve energy efficiency.

종래 입형 에어컨의 구조가 도 1에 간략하게 도시되어 있는 바, 이를 간단히 설명하면 다음과 같다.The structure of a conventional vertical air conditioner is briefly shown in FIG. 1, which will be briefly described as follows.

도 1과 같이, 종래의 에어컨은 박스체인 케이스(1)의 내부에는 내측으로 흡입되는 공기를 열교환하기 위한 열교환기(2)가 설치되어 있다.As shown in FIG. 1, the conventional air conditioner is provided with a heat exchanger 2 for heat-exchanging air sucked into the inside of the box chain case 1.

그리고, 상기 케이스(1)의 전면 하단부에는 외부 공기를 케이스(1)의 내부로 흡입하기 위한 흡입그릴(3)이 설치되어 있고, 상단부에는 상기 열교환기(2)에 열교환된 공기를 토출하기 위한 토출그릴(4)이 설치되어 있다.In addition, a suction grill 3 for sucking outside air into the case 1 is installed at the lower front end of the case 1, and an upper end portion for discharging the heat-exchanged air to the heat exchanger 2 is provided. The discharge grill 4 is provided.

또한, 상기 열교환기(2)의 하측에는 흡입그릴(3)을 통하여 흡입된 공기를 열교환기(2)로 송풍하기 위한 송풍팬(5)이 설치되어 있다.In addition, a blower fan 5 is provided below the heat exchanger 2 for blowing air sucked through the suction grill 3 to the heat exchanger 2.

상기와 같이 구성되어 있는 종래 에어컨은 전원이 인가되면 흡입그릴(3)을 통하여 흡입된 공기가 송풍팬(5)에 의하여 송풍되어 열교환기(2)를 통과하게 되고, 그와 같이 열교환기(2)를 통과하는 공기는 열교환기(2)에 의하여 열교환되어 차가운 공기가 되며, 그 차가운 공기는 토출그릴(4)을 통하여 에어컨의 외부로 토출되어 사용자가 시원함을 느끼게 된다.In the conventional air conditioner configured as described above, when power is applied, the air sucked through the suction grill 3 is blown by the blowing fan 5 to pass through the heat exchanger 2, and thus the heat exchanger 2 The air passing through) is exchanged by the heat exchanger 2 to become cold air, and the cold air is discharged to the outside of the air conditioner through the discharge grill 4 to make the user feel cool.

그러나, 상기와 같은 종래 에어컨은 열교환기(2)에서 열교환시에 온도 차이에 의하여 핀의 표면에 응축수가 발생이 되고, 그 발생되는 응축수가 핀들의 사이에 걸려서 공기의 흐름을 저해하게 되는데, 그와 같은 상태에서 적정량의 공기유량이 흐르도록 하기 위해서는 송풍팬(5)의 회전속도를 증가시켜야 하므로 그에 따른 에너지 이용 효율의 저하를 초래하는 문제점이 있었다.However, in the conventional air conditioner as described above, condensate is generated on the surface of the fin due to the temperature difference during the heat exchange in the heat exchanger 2, and the generated condensate is caught between the fins to hinder the flow of air. In order to flow the appropriate amount of air flow in such a state to increase the rotational speed of the blowing fan (5) there was a problem causing a decrease in the energy use efficiency accordingly.

상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 열교환기의 표면에 발생되는 응축수를 제거하여 열교환기를 통과하는 공기의 흐름을 저해하지 않도록 하는데 적합한 에어컨 열교환기의 응축수 제거장치를 제공함에 있다.The object of the present invention devised in view of the above problems is to provide a condensate removal device of an air conditioner heat exchanger suitable for removing condensate generated on the surface of the heat exchanger so as not to impede the flow of air passing through the heat exchanger.
