The cold air discharged at this time necessarily comes into contact with the upper portion of the front panel 15. Therefore, the upper portion of the front panel 15 is cooled by cold air to have a temperature lower than room temperature. Particularly, when the front panel 15 is made of tempered glass material, water droplets are continuously formed in the area A indicated by dotted lines. Flowing down will occur.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 패키지 에어컨의 토출구 하단의 전면패널을 가열하여 전면패널과 공기의 온도 차이를 감소시킴으로써 전면패널의 표면에 이슬이 맺히는 현상을 방지하기 위한 것이다.The present invention is to solve the above problems, it is to prevent the dew condensation on the surface of the front panel by reducing the temperature difference between the front panel and the air by heating the front panel of the lower discharge port of the package air conditioner.

이러한 목적을 달성하기 위한 본 발명은 전면 상부의 토출구로 냉기가 토출되는 패키지 에어컨에 있어서, 냉기가 토출구 하부에 위치하는 전면패널의 상부 안쪽에 열선을 구비하고, 상기 열선의 전원공급을 제어하는 제어부를 구비하여 상기 전면패널의 상부를 가열하는 것을 특징으로 하는 패키지 에어컨의 이슬 맺힘 방지구조를 제공한다.In order to achieve the above object, the present invention provides a package air conditioner in which cold air is discharged to an outlet of an upper portion of the front surface, wherein the cold air is provided with a heating wire inside an upper portion of the front panel positioned below the discharge hole, and controls a power supply of the heating wire. It provides a dew condensation preventing structure of the package air conditioner, characterized in that for heating the upper portion of the front panel.

상기 전면패널의 표면온도를 측정하는 온도측정센서를 추가로 구비하여, 상기 온도측정센서의 측정온도에 따라서 열선의 전원 인가 여부를 제어하는 것이 바람직하다.It is preferable to further include a temperature measuring sensor for measuring the surface temperature of the front panel, to control whether or not the hot wire power is applied in accordance with the measured temperature of the temperature measuring sensor.
