Description
본 고안은 전기히터에 관한 것으로, 더욱 상세하게는 자외선램프와 광촉매코팅막으로 구성된 광촉매장치를 장착하여 자외선램프 작동시 방사되는 자외선이 광촉매에 조사될 때 발생되는 광촉매반응으로 오염된 실내공기를 정화하는 광촉매식 전기히터에 관한 것이다.The present invention relates to an electric heater, and more particularly, equipped with a photocatalyst comprising an ultraviolet lamp and a photocatalyst coating film to purify indoor air contaminated by the photocatalytic reaction generated when the ultraviolet light emitted by the ultraviolet lamp is irradiated to the photocatalyst. A photocatalyst type electric heater.
일반적으로 오염된 실내공기는 오염된 대기와 함께 인체에 치명적인 해를 입힌다. 즉, 주거양식의 변화로 인한 단열, 냉방, 방음 등의 효과를 높이기 위하여 밀폐도가 증가된 실내에서 거주하는 시간이 늘어날 뿐만 아니라, 오염된 대기의 경우에는 자연적으로 정화되는 비율이 큰 반면 실내공기는 한정된 공간에서 계속해서 순환하므로 오염된 대기보다 더 심각한 폐해를 가져다 줄 우려가 있다. 또한, 에너지 보존을 위한 새로운 건축자재의 등장으로 오염물질의 방출이 더욱 증가하는 추세이다. 근래에는 밀페된 공간내에서 전기히터의 사용이 증대되고 있는 실정이며 실내의 오염된 공기를 정화하여 신선한 공기를 배출하는 공기정화기의 사용이 증대되고 있는 실정이다.In general, contaminated indoor air, along with the contaminated atmosphere, is harmful to humans. In other words, in order to increase the effect of insulation, cooling, and soundproofing due to the change of residential style, not only the time of living in the room with increased airtightness is increased, but also the polluted atmosphere has a large rate of natural purification but As circulates continuously in confined spaces, there is a risk of causing more serious harm than polluted atmosphere. In addition, the emergence of new building materials for energy conservation is increasing the emission of pollutants. In recent years, the use of electric heaters in an enclosed space is increasing, and the use of an air purifier for purifying polluted air in a room and discharging fresh air is increasing.
그러나, 밀폐된 공간 내에서 전기히터를 계속하여 장시간 사용하게 되면 실내공기가 오염되고 종래 공기정화기를 사용하는 경우라도 공기정화에는 한계가 있다. 특히, 미세한 유해물질이나 세균의 경우에는 공기정화기로도 걸러지지 않고 그대로 외부로 배출될 염려가 있으며, 세균의 경우에는 공기정화기 내에서 번식할 우려도 있다.However, if the electric heater is used continuously for a long time in an enclosed space, indoor air is contaminated and there is a limit in air purification even when using a conventional air purifier. In particular, in the case of minute harmful substances or bacteria may be discharged to the outside as it is not filtered even by the air purifier, in the case of bacteria there is a fear of breeding in the air purifier.
본 고안은 전술한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로서 전기히터에 자외선램프와 광촉매코팅막으로 구성된 광촉매장치를 장착하여 자외선램프 작동시 방사되는 자외선이 광촉매에 조사될 때 발생되는 광촉매반응으로 오염된 실내공기를 정화하는 광촉매식 전기히터를 제공하는데 목적이 있다. 또한 자외선램프에 광촉매가 코팅된 유리섬유를 감싼 광촉매장치를 전기히터 내부에 내장하여 자외선 램프 작동시 방사되는 자외선이 광촉매에 조사될 때 발생되는 광촉매반응으로 미세한 유해물질까지도 정화하고 세균도 박멸할 수 있는 광촉매식 전기히터를 제공하는데 그 목적이 있다.The present invention was devised to solve the above-mentioned problems. As a photocatalytic reaction is generated when an ultraviolet ray emitted during the operation of an ultraviolet lamp is irradiated on the photocatalyst by mounting a photocatalyst device composed of an ultraviolet lamp and a photocatalyst coating film on an electric heater. It is an object of the present invention to provide a photocatalytic electric heater for purifying contaminated indoor air. In addition, the photocatalytic device that wraps the glass fiber coated with the photocatalyst on the UV lamp is embedded inside the electric heater to purify even the minute harmful substances and eradicate the bacteria by the photocatalytic reaction generated when the UV light emitted by the UV lamp is irradiated on the photocatalyst. The purpose is to provide a photocatalytic electric heater.
전술한 바와 같은 목적을 달성하기 위하여 본 고안은 본체(50), 히터장치(10), 스위치를 겸한 온도조절장치(20) 및 전원플러그(60)를 포함하여 이루어진 전기히터(100)에 있어서, 상기 전기히터(100)는 자외선램프(41)와 광촉매코팅막(70)으로 구성된 광촉매장치를 장착한 것을 특징으로 한다.In order to achieve the object described above, the present invention includes an electric heater 100 including a main body 50, a heater device 10, a thermostat device 20 serving as a switch, and a power plug 60. The electric heater 100 is characterized in that the photocatalyst device composed of an ultraviolet lamp 41 and the photocatalyst coating film 70 is mounted.
본 고안의 광촉매식 전기히터에서 광촉매장치는 바형태의 자외선램프와 자외선램프의 외측을 감싸며 광촉매코팅막이 형성된 유리섬유로 구성된 것을 특징으로 하며 자외선램프는 254nm 또는 365nm인 것을 특징으로 하고 광촉매 코팅막은 산화티타늄, 삼산화텅스텐, 산화아연, 이산화주석 및 산화철로 이루어진 그룹 중에서 선택되는 하나 이상의 광촉매로 이루어진 것을 특징으로 한다.In the photocatalytic electric heater of the present invention, the photocatalyst device is characterized by consisting of a bar-shaped ultraviolet lamp and a glass fiber having a photocatalyst coating film formed around the outside of the ultraviolet lamp, and the ultraviolet lamp is 254 nm or 365 nm, and the photocatalyst coating film is oxidized. It is characterized by consisting of at least one photocatalyst selected from the group consisting of titanium, tungsten trioxide, zinc oxide, tin dioxide and iron oxide.
또한 본 고안의 광촉매식 전기히터에서 광촉매장치는 자외선램프와 유리섬유 사이에 개재되어 유리섬유를 자외선 램프의 표면으로부터 이격시키는 단열부재를 더 포함하여 이루어진 것을 기술적 특징으로 한다.In addition, the photocatalyst in the photocatalytic electric heater of the present invention is characterized in that it further comprises a heat insulating member interposed between the ultraviolet lamp and the glass fiber to separate the glass fiber from the surface of the ultraviolet lamp.
이하 본 고안에 따른 광촉매식 전기히터의 바람직한 실시예를 통하여 전술한 바와 같은 구성들의 특징과 그 작용을 상세히 설명하기로 한다. 첨부된 도면의 도 1은 본 고안의 광촉매식 전기히터를 나타낸 사시도이고, 도 2는 본 고안의 광촉매식 전기히터를 나타낸 정면도이며, 도 3은 본 고안의 광촉매식 전기히터에 장착된 광촉매장치를 나타낸 단면도이고, 도 4는 본 고안의 광촉매식 전기히터에 장착된 전기히터장치를 나타낸 단면도이며, 도 5는 본 고안의 또 다른 광촉매식 전기히터를 나타낸 사시도이다.Hereinafter will be described in detail the features and operation of the configuration as described above through a preferred embodiment of the photocatalyst-type electric heater according to the present invention. 1 is a perspective view showing a photocatalyst electric heater of the present invention, Figure 2 is a front view showing a photocatalyst electric heater of the present invention, Figure 3 is a photocatalyst device mounted on the photocatalyst electric heater of the present invention 4 is a cross-sectional view showing an electric heater device mounted on the photocatalyst electric heater of the present invention, Figure 5 is a perspective view showing another photocatalyst electric heater of the present invention.
본 고안의 전기히터에서 광촉매장치(40)는 히터장치의 상부 또는 하부에 설치되는 자외선램프(41) 및 자외선 램프(41)를 감싸며 광촉매코팅막(70)이 형성된 유리섬유(42)로 구성된다. 본 고안의 전기히터에서 자외선램프(41)는 투명한 바(BAR)형태의 유리판(411)과 유리판(411)의 양단에 장착된 베이스(412)와, 베이스(412)의 내측에 장착된 히팅필라멘트(413) 및 히팅필라멘트(413)와 연결되어 전기히터 본체(10)내에 설치된 전원단자와 전기적으로 접속되는 램프핀(414)으로 구성된다.In the electric heater of the present invention, the photocatalyst device 40 is composed of a glass fiber 42 formed around the ultraviolet lamp 41 and the ultraviolet lamp 41 installed on the upper or lower portion of the heater device and having a photocatalytic coating film 70 formed thereon. In the electric heater of the present invention, the ultraviolet lamp 41 has a glass bar 411 in the form of a transparent bar (BAR) and a base 412 mounted at both ends of the glass plate 411, and a heating filament mounted inside the base 412. And a lamp pin 414 connected to the 413 and the heating filament 413 and electrically connected to a power terminal installed in the electric heater main body 10.
본 고안에서 사용되는 광촉매는 자외선램프를 이용하여 살균작용을 하는데 사용하는 자외선은 254nm 또는 365nm를 사용할 수 있다. 본 고안에서 254nm 만을 사용하거나 365nm 만을 사용할 수 있으나 254nm 또는 365nm를 한꺼번에 같이 병행하여 사용하는 경우 살균효과가 더욱 현저하게 나타났다. 본 고안의 히터에서 254nm 또는 365nm를 병행하여 광촉매를 사용하는 경우 살균 뿐만 아니라 휘발성 유기물질, 질소산화물 및 황산화물까지 제거시키는 효과가 있다. The photocatalyst used in the present invention may use 254 nm or 365 nm for ultraviolet rays used to sterilize using an ultraviolet lamp. In the present invention, only 254nm or 365nm can be used, but when 254nm or 365nm is used in parallel, the sterilization effect was more remarkable. In the case of using the photocatalyst in parallel with 254nm or 365nm in the heater of the present invention, there is an effect of removing not only sterilization but also volatile organic substances, nitrogen oxides and sulfur oxides.
그리고 본 고안의 전기히터에서 유리섬유(42)는 단열필름(43)에 의해 자외선램프(41)의 유리판(411)과 이격된다. 본 고안의 전기히터에서 단열필름(43)이 자외선램프(41)의 유리판(411) 양단과 유리섬유(42)의 양단 사이에 개재됨으로써 유리섬유(42)는 유리판(411)으로부터 이격된 상태로 유리판(411)을 감싸게 된다.In the electric heater of the present invention, the glass fiber 42 is spaced apart from the glass plate 411 of the ultraviolet lamp 41 by the heat insulating film 43. In the electric heater of the present invention, the insulating film 43 is interposed between both ends of the glass plate 411 of the ultraviolet lamp 41 and both ends of the glass fiber 42, so that the glass fiber 42 is spaced apart from the glass plate 411. The glass plate 411 is wrapped.
한편 본 고안의 전기히터에서 유리섬유(42)가 자외선램프(41)의 유리판(411)을 감싸기 전에 유리섬유(42)의 표면에는 이산화티탄(TiO2)을 주성분으로 삼산화팅스텐(WO3), 산화아연(ZnO), 이산화주석(SnO2), 산화철(Fe2O3) 등과 같은 광촉매 반도체 성분이 혼합되어 만들어진 혼합액이 코팅되어 광촉매 도금막이 형성되며, 상기 광촉매도금막이 형성된 유리섬유(42)에는 팔라듐(Pd) 금(Au) 백금(Pt) 은(Ag) 등과 같은 산화촉매 또는 몰리브덴(Mo) 니오브(Nb) 붕소(B) 세륨(Ce) 크롬(Cr) 등과 같은 전이금속이 침투된다. 자외선램프(41)를 감싸는 유리섬유(42)에 도금막층을 형성하는 과정은 미국특허 제6,135,838호에 상세히 기재되어 있다.Meanwhile, before the glass fiber 42 surrounds the glass plate 411 of the ultraviolet lamp 41 in the electric heater of the present invention, the surface of the glass fiber 42 has titanium dioxide (TiO 2 ) as a main component of tin oxide (WO 3 ). , A mixed solution made by mixing a photocatalytic semiconductor component such as zinc oxide (ZnO), tin dioxide (SnO 2 ), iron oxide (Fe 2 O 3 ), etc. is coated to form a photocatalyst plating film, and the glass fiber 42 having the photocatalyst plating film formed thereon. An oxide catalyst such as palladium (Pd), gold (Au), platinum (Pt), silver (Ag), or a transition metal such as molybdenum (Mo) niobium (Nb) boron (B) cerium (Ce) chromium (Cr) or the like penetrates. The process of forming the plating layer on the glass fiber 42 surrounding the ultraviolet lamp 41 is described in detail in US Pat. No. 6,135,838.
본 고안의 전기히터에서 광촉매장치(40)의 자외선램프(41)가 작동하게 되면 자외선 램프(41)에서 방사되는 자외선이 유리섬유(42)의 광촉매도금막 및 산화촉매, 전이금속에 조사되어 자유 전자-전기홀을 형성하게 된다. 상기 자유전자-전기홀은 공기중에 함유된 수분이나 산소와 반응하여 수산화기(radical)를 생성하게 되며, 상기 수산화기는 각종 유기 및 무기 반응원과 반응하여 오염원의 특성을 안정된 상태로 변화시키게 된다. 특히, 수산화기는 소독이나 살균에 널리 사용되고 있는 염소나 치아염소산, 과산화수소, 오존 등보다 훨씬 강한 산화력을 갖는다.When the ultraviolet lamp 41 of the photocatalyst 40 is operated in the electric heater of the present invention, ultraviolet rays emitted from the ultraviolet lamp 41 are irradiated to the photocatalyst plating film, the oxidation catalyst, and the transition metal of the glass fiber 42 to be free. Electron-electric holes are formed. The free electron-electron hole reacts with moisture or oxygen contained in air to generate a radical, and the hydroxyl group reacts with various organic and inorganic reactants to change the characteristics of the pollutant to a stable state. In particular, the hydroxyl group has a much stronger oxidizing power than chlorine, hypochlorite, hydrogen peroxide, ozone and the like widely used for disinfection and sterilization.
따라서 광촉매장치(40)을 통과하는 공기가 광촉매장치(40)로부터 발생되는 자유-전자-전기홀과 접촉하게 되면, 공기중에 함유된 수분이나 산소가 자유 전자-전기홀과 반응하여 수산화기를 생성하게 되고, 이 수산화기로 인해 공기중에 함유된 유해물질이 안정된 상태로 분해되고, 각종 세균이 박멸되며 악취가 제거된다.Therefore, when the air passing through the photocatalytic device 40 comes into contact with the free-electron-electron hole generated from the photocatalytic device 40, moisture or oxygen contained in the air reacts with the free electron-electron hole to generate hydroxyl groups. Due to this hydroxyl group, harmful substances contained in the air are decomposed in a stable state, various bacteria are eliminated, and odors are removed.
이상과 같이 본 고안에 따른 광촉매식 전기히터의 실시예를 첨부된 도면을 참조로 설명하였으나, 본 고안은 명세서에 상세히 설명된 실시예와 도면에 한정되지 아니하며, 고안의 기술사상 범위 내에서 다양한 변형이 이루어질 수 있다.As described above with reference to the accompanying drawings, an embodiment of the photocatalyst-type electric heater according to the present invention, the present invention is not limited to the embodiments and drawings described in detail in the specification, various modifications within the technical scope of the invention This can be done.
이상에서 상세히 설명한 바와 같은 본 고안 광촉매식 전기히터에 따르면 밀폐공간에서 오염된 공기는 광촉매장치를 통과하면서 광촉매 반응으로 인해 정화됨으로써 실내의 오염된 공기를 효과적으로 정화할 수 있는 장점이 있다. 또한 광촉매 반응시 발생되는 수산화기로 인해 공기중에 함유된 유해물질이 안정된 상태로 분해되고 각종 세균이 박멸되며 악취가 제거될 뿐만 아니라 전기히터 본체 내에 서식하는 각종 세균도 박멸할수 있는 장점이 있으며 본 고안의 히터에서 254nm 또는 365nm를 병행하여 광촉매를 사용하는 경우 살균 뿐만 아니라 휘발성 유기물질, 질소산화물 및 황산화물까지 제거시키는 효과가 있다. According to the present invention photocatalyst type electric heater as described in detail above, the contaminated air in the enclosed space is purified by the photocatalytic reaction while passing through the photocatalyst, thereby effectively purifying the contaminated air in the room. In addition, due to the hydroxyl group generated during the photocatalytic reaction, harmful substances contained in the air are decomposed in a stable state, various bacteria are eliminated, odors are removed, and various bacteria in the electric heater body are also eliminated. In the case of using a photocatalyst in parallel with 254 nm or 365 nm in a heater, sterilization as well as volatile organic substances, nitrogen oxides and sulfur oxides are effective.
