이와 같은 프로젝션 텔레비젼의 개략적인 단면도가 도 1에 도시된다.A schematic cross sectional view of such a projection television is shown in FIG.

Later, the image signal is contained and projected onto the screen of the main body 10.

한편, 상기 광학계(45)에서 설치된 고출력의 램프에서는 고열이 발생되는데, 상기 LCD 패널은 주지된 바와 같이 열에 미약한 소자이다. On the other hand, high heat is generated in the high power lamp installed in the optical system 45, and the LCD panel is a device that is weak in heat as is well known.

이와 같은 고출력의 램프와 LCD 소자 사이의 냉각을 위하여 본체(10) 내측에는 하나 이상의 방열 팬(40)이 설치된다. One or more heat dissipation fans 40 are installed inside the main body 10 for cooling between the high power lamp and the LCD device.

또한, 상기 방열 팬(40)에는 광학계(45)에서 방열된 고열의 공기 유동이 본체(10)에 잔류되지 않고 외부로 유도하도록 방열 덕트(50)가 연통되어 설치되고, 전방에는 외기를 흡기하기 위한 슬릿형 흡기구(15)가 형성되며, 흡기구(15)에는 외부로부터의 먼지를 차단하기 위한 필터(65)가 설치된다.In addition, the heat dissipation fan 40 is installed to communicate with the heat dissipation duct 50 so that the high-temperature air flow radiated by the optical system 45 to the outside without remaining in the main body 10, the front air intake A slit type inlet 15 is formed, and the inlet 15 is provided with a filter 65 for blocking dust from the outside.

상기와 같은 목적을 달성하기 위해 본 발명은, 방열 팬에 의해 외부 공기를 유입하는 프로젝션 텔레비젼에 있어서, 방열 팬에 의한 공기가 유입되는 유입구에는 광촉매가 코팅된 필터가 설치되고, 필터를 활성화시키기 위한 광원이 프로젝션 텔레비젼의 내부에 설치되는 광촉매 필터가 구비된 프로젝션 텔레비젼을 제공한다.In order to achieve the above object, the present invention, in a projection television that introduces the outside air by the heat dissipation fan, the inlet through which the air is introduced by the heat dissipation fan is provided with a filter coated with a photocatalyst, for activating the filter Provided is a projection television equipped with a photocatalyst filter in which a light source is installed inside the projection television.

It has a feature that can be maintained.

본 발명의 광촉매 필터에 코팅되는 광촉매는 천연 정화 작용의 물질로서, 일반적으로 광을 받으면 촉매 반응을 일으키는 물질이며, 광촉매 중에는 이산화티타늄(TiO2)이 가장 많이 사용되는데, 이는 이산화티타늄이 내산성, 내알카리성 등이 우수하며 인체에 무해하기 때문이다.The photocatalyst coated on the photocatalyst filter of the present invention is a material of a natural purification action, and generally is a material that causes a catalytic reaction when light is received. Among the photocatalysts, titanium dioxide (TiO 2 ) is most frequently used. This is because it is excellent in alkali and harmless to human body.

이러한 광촉매 물질은 각종 오염 물질을 무해한 물질로 변화시켜 주는 친환경적 소재로 밝혀져 최근에 주택설비나 건설 자재 및 환경 정화 장치 등 다양한 용도로 활용되고 있다.

도 2에서, 필터(30) 표면에는 전술한 광촉매로서 초미립자(나노 단위의 입자)의 산화티탄을 무기질 바인더와 배합하여 소정의 형상재 즉, 경량 수지재에 고경도 투명한 막을 형성하도록 코팅되어 있는 것으로, 표면의 코팅 막에 광원(20)이 수렴하면서 활성화되어 유동 공기를 정화시키는 것이다. In FIG. 2, the surface of the filter 30 is coated with titanium oxide of ultrafine particles (particles in nano units) with an inorganic binder as a photocatalyst to form a high hardness transparent film on a predetermined shape, that is, a lightweight resin material. , The light source 20 converges on the surface coating film to activate the purified air.
