It provides a passageway through which internal air is discharged to the outside.
예를 들어, 유입부(30)와 배출부(40)에는 외부로부터의 빗물 유입을 방지하는 보호 가이드(310, 410)가 형성되도록 구성될 수 있다.For example, the inlet part 30 and the outlet part 40 may be configured such that protection guides 310 and 410 are formed to prevent the inflow of rainwater from the outside.
예를 들어, 도 3에 확대 표현된 바와 같이, 유입부(30)는, 유입 보호 가이드(310), 외측 유입구(320), 내측 유입구(330) 및 유입 필터(340)를 포함할 수 있다.For example, as enlarged in FIG. 3, the inlet 30 may include an inlet protection guide 310, an outer inlet 320, an inner inlet 330, and an inlet filter 340.
유입 보호 가이드(310)는 하우징(5)의 후면부에서 하방 즉, 지면을 향하여 연장 형성되어 있으며, 외부로부터의 빗물 유입을 방지하는 기능을 수행한다.The inflow protection guide 310 extends downward from the rear side of the housing 5, that is, toward the ground, and serves to prevent rainwater from inflowing from the outside.

외측 배출구(420)는 배출 보호 가이드(410)의 하부에 형성되어 있으며, 하우징(5)의 내부 공기가 외부로 배출되는 최종 통로를 제공한다.The outer outlet 420 is formed under the discharge protection guide 410 and provides a final passage through which the internal air of the housing 5 is discharged to the outside.
내측 배출구(430)는 외측 배출구(420)의 내측에 위치하며, 배출 보호 가이드(410)의 하단보다 높은 위치에 형성되어 있다. 이러한 내측 배출구(430)는 외측 배출구(420)를 통해 유입된 빗물이 하우징(5)의 내부로 유입되는 것을 방지하고, 하우징(5)의 내부 공기가 외측 배출구(420)를 경유하여 하우징(5)의 외부로 배출되도록 하는 통로를 제공하는 기능을 수행한다.The inner discharge port 430 is located inside the outer discharge hole 420 and is formed at a position higher than the lower end of the discharge protection guide 410. The inner outlet 430 prevents rainwater introduced through the outer outlet 420 from entering the interior of the housing 5, and the internal air of the housing 5 passes through the outer outlet 420. It serves to provide a passage to be discharged to the outside of the).

For example, the second circulation fan may be installed at any position between the inlet 30 and the first circulation fan 52, but preferably, the second circulation fan is the inlet 30 and the display panel. It can be installed between the (20).
배출팬(56)은 제1 순환팬(52)과 제2 순환팬(54)에 의해 순환된 내부 공기를 배출부(40)를 통해 배출시키는 기능을 수행한다. 예를 들어, 배출팬(56)은 배출부(40)에 인접한 위치에 설치될 수 있으나, 그 설치 위치가 이에 한정되는 것은 아니다.The discharge fan 56 discharges the internal air circulated by the first circulation fan 52 and the second circulation fan 54 through the discharge unit 40. For example, the discharge fan 56 may be installed at a position adjacent to the discharge portion 40, but the installation position is not limited thereto.
