And the like.
그러나 상기와 같은 기존의 공기정화기는 단순히 공기를 필터링만 하는 구성이어서 사용자에게 완벽하게 정화된 공기를 공급하기에는 미흡한 점이 있어서 근래에는 광촉매를 이용한 공기정화기가 많이 제작되고 있다.However, the conventional air purifier as described above is simply configured to filter the air, so that it is insufficient to supply completely purified air to the user. Recently, many air purifiers using photocatalysts have been manufactured.
광촉매는 알려진 바와 같이 자외선과 같은 빛 에너지를 받았을 때, 빛에 의해 화학반응을 촉진하거나 촉매작용을 갖게되는 물질을 말하며, 대표적인 촉매반응으로 물분자분해 촉매반응, 유기물질분해 촉매반응, 친수성표면 개질반응 등이 있다. 이러한 광촉매는 각종 오염물질들을 산화 및 분해시키면서 탈취효과도 탁월하며, 사용 수명도 반영구적이어서 공기정화분야나 정수분야 등 다양한 분야에 사용되고 있다.Photocatalyst refers to a substance that promotes or catalyzes a chemical reaction by light when it receives light energy such as ultraviolet rays.

선행기술은 광촉매가 적층된 필터; 상기 필터와 이격되도록 배치되되, 이동하면서 광에너지를 방출하는 광원; 및 상기 광원이 장착되고 상기 광원으로부터 방출되는 광에너지가 상기 필터의 일부영역에 미치도록 상기 광원을 작동시키는 구동 유닛;으로 구성된다.The prior art includes a filter in which a photocatalyst is stacked; A light source disposed to be spaced apart from the filter and emitting light energy while moving; And a driving unit in which the light source is mounted and operates the light source so that the light energy emitted from the light source reaches a partial region of the filter.

이에 따라, 선행기술은 필터에 코팅된 광촉매가 광원부에 의해 촉매반응을 일으키므로 필터의 표면에 군집되는 세균이나 곰팡이와 같은 오염물질을 분해하고 악취를 제거하는 구성이다.Accordingly, the prior art is configured to decompose contaminants such as bacteria and fungi, which are clustered on the surface of the filter and remove odors because the photocatalyst coated on the filter causes a catalytic reaction by the light source unit.
그런데, 선행기술은 광원부가 이동유닛에 의해 왕복이동하면서 필터에 빛을 조사함에 따라 필터에 부분적으로만 빛이 조사된 후 일정시간 이후에 다시 빛이 조사되는 구성이므로 광촉매제의 원활한 촉매반응을 기대할 수 없는 문제점이 있다.However, in the prior art, since the light source is irradiated to the filter while being reciprocated by the mobile unit, the light is partially irradiated to the filter and then the light is irradiated again after a certain time, so that a smooth catalytic reaction of the photocatalyst may be expected. There is no problem.
또한, 선행기술은 이동유닛의 구성이 복잡하여 제작이 번거롭고 제작비용이 많이 소요되는 문제점도 있다.In addition, the prior art also has a problem in that the configuration of the mobile unit is complicated and the production is cumbersome and takes a lot of production costs.

Both ends are fitted in a flowable state.
즉, 집광렌즈(130)나 확산렌즈(140)는 렌즈슬롯(161)에 유동가능한 상태로 결합됨에 따라 전술한 구동모터(152)에 의한 램프홀더(120)의 회전이나 프리필터(P)를 통과한 공기의 풍압에 의해 유동하면서 자외선의 조사범위를 확장시킨다.That is, as the condenser lens 130 or the diffusion lens 140 is coupled to the lens slot 161 in a flowable state, the condenser lens 130 or the preliminary filter P or the rotation of the lamp holder 120 by the above-described driving motor 152 may be used. The irradiation range of ultraviolet rays is expanded while flowing by the wind pressure of the air which passed.
상기와 같은 구성요소를 포함하는 본 발명의 작동 및 작용을 설명한다.It describes the operation and operation of the present invention including the above components.
본 발명의 광촉매 살균모듈은 공기정화기(10)의 케이스 내에 설치되면서 프리필터(P)의 후방에 설치된다.Photocatalyst sterilization module of the present invention is installed in the rear of the pre-filter (P) while being installed in the case of the air purifier (10).
자외선 램프(L)는 공기정화기(10)의 흡입팬이 작동함에 따라 발광한다.The ultraviolet lamp L emits light as the suction fan of the air purifier 10 operates.
이때, 집광렌즈(130)는 자외선 램프(L)의 자외선을 집광상태로 프리필터(P)측으로 조사하면서 공기 중의 세균을 살균시킨다.At this time, the condenser lens 130 sterilizes the bacteria in the air while irradiating the ultraviolet rays of the ultraviolet lamp L toward the prefilter P in a condensed state.
그리고, 확산렌즈(140)는 자외선 램프(L)의 자외선을 확산상태로 자외선 광촉매 에어필터(H)측으로 조사하면서 자외선을 광촉매 에어필터(H)의 전역으로 확산시켜 광촉매 에어필터(H)에 코팅된 광촉매제의 반응을 유도한다.The diffusion lens 140 diffuses the ultraviolet rays to the entire area of the photocatalyst air filter H while irradiating the ultraviolet rays of the ultraviolet lamp L toward the ultraviolet photocatalyst air filter H in a diffusion state and coating the photocatalyst air filter H on the photocatalyst air filter H. Induce the reaction of the photocatalyst.
한편, 구동모터(152)는 회전축(151)을 통해 램프홀더(120)를 왕복운동시킨다. 이에 따라 집광렌즈(130) 및 확산렌즈(140)는 램프홀더(120)와 함께 왕복운동하면서 자외선의 조사범위를 확장시키며, 렌즈슬롯(161)을 통해 유동하면서 자외선의 조사범위를 더욱 확장시킨다.On the other hand, the drive motor 152 reciprocates the lamp holder 120 through the rotation shaft 151. Accordingly, the condenser lens 130 and the diffusion lens 140 reciprocate with the lamp holder 120 to expand the irradiation range of ultraviolet rays, and further extend the irradiation range of ultraviolet rays while flowing through the lens slot 161.
이상에서 살펴본 바와 같이 본 발명에 따른 자외선의 집광 및 확산기능을 갖는 공기정화용 광촉매 살균모듈은, 광촉매 에어필터(H)에 광촉매제가 코팅됨에 따라 프리필터(P)를 통과한 공기의 필터링과 함께 공기에 포함된 오염물질이나 세균을 분해시킬 수 있으며, 광촉매 에어필터(H)의 표면에 군집되는 곰팡이나 세균이 살균되므로 더욱 위생적인 공기를 제공할 수 있다.As described above, the air purification photocatalyst sterilization module having the function of collecting and diffusing ultraviolet rays according to the present invention, as the photocatalyst is coated on the photocatalyst air filter (H), air together with the filtering of the air passing through the prefilter (P). It can decompose contaminants or bacteria contained in, and can be provided more hygienic air because the fungus or bacteria are sterilized on the surface of the photocatalyst air filter (H).
특히, 본 발명은 자외선 집광확산기(100)의 집광렌즈(130)가 자외선 램프(L)의 자외선을 프리필터(P) 측으로 집광상태로 제공하므로 자외선의 살균력이 강화되어 프리필터(P)를 통과한 공기가 원활히 살균될 수 있으며, 자외선 집광확산기(110)의 확산렌즈(140)가 자외선 램프(L)의 자외선을 광촉매 에어필터(H) 측으로 확산상태로 제공함에 따라 자외선이 광촉매 에어필터(H)의 전역에 고르게 조사되므로 광촉매 에어필터(H)의 표면의 광촉매제가 원활하게 촉매반응을 일으킬 수 있다.Particularly, in the present invention, since the condenser lens 130 of the ultraviolet condenser diffuser 100 condenses the ultraviolet light of the ultraviolet lamp L toward the prefilter P side, the sterilizing power of the ultraviolet light is enhanced to pass through the prefilter P. One air can be sterilized smoothly, and as the diffusion lens 140 of the ultraviolet condenser diffuser 110 provides the ultraviolet rays of the ultraviolet lamp L to the photocatalyst air filter H in a diffusion state, the ultraviolet rays are photocatalytic air filters H. Since it is evenly irradiated across the photocatalyst, the photocatalyst on the surface of the photocatalyst air filter (H) may smoothly catalyze the reaction.
또한, 자외선 집광확산기(100)를 구성하는 램프홀더(120)가 회전축(151)과 구동모터(152)에 의해 왕복운동함에 따라 집광렌즈(130)와 확산렌즈(140)가 함께 유동하므로 자외선의 조사범위가 확장될 수 있다.In addition, as the lamp holder 120 constituting the ultraviolet light diffuser 100 reciprocates by the rotation shaft 151 and the driving motor 152, the light condenser lens 130 and the diffusion lens 140 flow together. The scope of investigation can be extended.
더욱이, 집광렌즈(130)나 확산렌즈(140)가 렌즈유동부재(160)에 의해 유동가능한 상태로 램프홀더(120)에 결합됨에 따라 렌즈가 램프홀더(120)의 유동이나 프리필터(P)를 통과한 공기의 풍압에 의해 유동하므로 자외선의 조사범위가 더욱 확장될 수 있다.Furthermore, as the condenser lens 130 or the diffuser lens 140 is coupled to the lamp holder 120 in a state in which the lens flow member 160 is movable by the lens flow member 160, the lens is moved by the lamp holder 120 or the prefilter P. FIG. Since the flow through the air pressure of the air passing through the ultraviolet irradiation range can be further extended.
