이러한 문제점을 해결하기 위하여, 본 출원인이 기 출원한 대한민국 특허출원 제2009-0036439호에 의하면, 양극 산화 반응을 이용하여 다공질의 무기 피막으로 이루어지는 무기막을 제조하고, 이를 담체에 적용함으로써, 가스 정화 등 기체 반응에 이용 가능한 담체 구조와 그 담체의 제조 방법이 제공된다.In order to solve this problem, according to Korean Patent Application No. 2009-0036439 filed by the present applicant, an inorganic membrane made of a porous inorganic film is prepared using an anodic oxidation reaction, and applied to the carrier to purify the gas. A carrier structure usable for gas reaction and a method for producing the carrier are provided.
그러나 이러한 담체 구조는 소정 온도 조건, 바람직하게는 200 내지 250°C에서 촉매 반응을 함으로써 동작하게 되므로, 원동기의 배기 가스와 같이 이미 가열된 고온의 기체를 정화하는데 주로 사용되는 구조라고 할 것이다. 즉, 종래 기술의 담체 구조만으로는 상온의 공기를 정화하기 어려운 문제점이 있다.However, since the carrier structure is operated by catalysis at a predetermined temperature condition, preferably 200 to 250 ° C., it will be said that the carrier structure is mainly used to purify hot gas that is already heated, such as the exhaust gas of the prime mover. That is, there is a problem that it is difficult to purify air at room temperature only with the carrier structure of the prior art.

The air passing through the inlet 100 may pass through the air purifying module 200 to the air outlet 300.
이하에서는 본 발명의 일 구성요소인 공기정화모듈(200)과 그 작동 원리에 대해 상세히 설명하기로 한다.Hereinafter will be described in detail with respect to the air purification module 200 and its operation principle of one component of the present invention.
공기정화모듈(200)은 필터부(210)와 히터(220)로 구성된다. 필터부(210)는 공기유입구(100)로부터 유입된 공기가 통기(通氣) 가능한 구조여야 한다. 통기 가능하다는 의미는 기체가 통과할 수 있도록 구성되는 구조를 의미한다. 즉 정화될 공기 중의 입자가 필터부(210)의 표면과 충돌하면서 통과할 수 있는 구조가 되어야 한다. 한편 필터부(210)의 표면에는 다수의 기공을 포함하는 무기 피막이 형성되고 상기 무기 피막의 일부 또는 전부에 촉매 모액을 담지시켜 촉매층이 형성된다. 히터(220)는 필터부(210)를 소정의 온도 조건으로 유지함으로써 필터부(210)를 통과하는 공기가 촉매 반응을 일으키도록 한다. 촉매 반응을 일으키기 위해 필터부(210)는 200~250℃를 유지하는 것이 바람직하다.The air purification module 200 includes a filter 210 and a heater 220. The filter unit 210 should have a structure in which air introduced from the air inlet 100 is vented. By ventable means a structure configured to allow gas to pass through. In other words, the particles in the air to be purified should be a structure that can pass while colliding with the surface of the filter unit 210. Meanwhile, an inorganic film including a plurality of pores is formed on the surface of the filter unit 210, and a catalyst layer is formed by supporting a catalyst mother liquid on part or all of the inorganic film. The heater 220 maintains the filter unit 210 at a predetermined temperature so that air passing through the filter unit 210 causes a catalytic reaction. In order to cause a catalytic reaction, the filter unit 210 preferably maintains 200 to 250 ° C.
도 2를 참조하면, 공기정화모듈(200)의 필터부(210)는 다수의 필터판(211)을 이격 적층시켜서 필터판(211) 사이로 공기가 통기되게 구성할 수 있다. 필터판(211)에는 다수의 통기공(213)을 형성하여 공기가 지나갈 때 접촉되는 면적을 넓힘으로써 촉매 반응을 더욱 효과적으로 일으키게 할 수 있다. 또한 히터(220)는 막대 형상이면서 다수의 필터판(211)을 관통하며 필터판(211)과 접합되게 구성할 수 있다. 히터(220)는 PTC 히터를 사용할 수도 있고, 필터판(211)의 넓이나 개수에 따라 히터(220)의 개수도 조절할 수 있을 것이다.Referring to FIG. 2, the filter unit 210 of the air purification module 200 may be configured to allow the air to be vented between the filter plates 211 by stacking a plurality of filter plates 211 apart from each other. In the filter plate 211, a plurality of vent holes 213 may be formed to increase the area contacted when the air passes, thereby making the catalytic reaction more effective. In addition, the heater 220 may have a rod shape and penetrate the plurality of filter plates 211 and be bonded to the filter plates 211. The heater 220 may use a PTC heater, and the number of heaters 220 may also be adjusted according to the width or number of filter plates 211.
한편 필터부(210)는 원통 등과 같이 통형으로 형성됨으로써 통 내부를 기체가 통과할 수 있게 구성될 수도 있다. 또는 스파이럴(spiral) 형태로 롤링되어 통기 가능하게 구성될 수도 있다. 이와 같이 필터부(210)는 다양한 구조가 가능할 것이므로 그 형상을 한정하지 않고, 통기 가능하게 구성되는 것이라면 본 발명의 기술적 사상을 대변하는 것으로 이해되어야 할 것이다.Meanwhile, the filter unit 210 may be formed in a cylindrical shape such as a cylinder to allow gas to pass through the inside of the cylinder. Alternatively, it may be rolled in a spiral form and configured to be breathable. As described above, the filter unit 210 may be configured in various ways, and thus, the present invention is not limited to the shape, and it is to be understood that the filter unit 210 represents the technical idea of the present invention.
필터부(210)의 표면에 다수의 기공을 포함하는 무기 피막을 형성하고, 무기 피막에 촉매 모액을 담지시켜 촉매층을 형성하기 위해서는 양극 산화 반응을 이용한다. 양극 산화 반응에 의하면 전해 반응을 이용하여 금속 표면에 형성되는 산화물이나 질화물의 피막을 성장시키는 공정을 수행할 수 있다.In order to form an inorganic film including a plurality of pores on the surface of the filter unit 210, and to carry the catalyst mother liquid on the inorganic film, an anodic oxidation reaction is used. According to the anodic oxidation reaction, a process of growing an oxide or nitride film formed on the metal surface using an electrolytic reaction can be performed.
전해액을 통해 직류 전류를 흘리면 음극 금속에서는 수소가 발생하고 양극 금속(알루미늄(Al) 합금, 티타늄(Ti), 아연(Zn), 마그네슘(Mg), 니오븀(Nb) 등의 금속)에서는 산소가 발생하는데, 이 때 형성된 산소는 양극 금속과 반응하여 금속 산화물 피막을 형성시킨다. 이 과정에서 전해액은 생성된 산화물 피막을 미세하게 용해시키게 되는데, 이 때 용해 속도와 상기 산화물 피막의 형성 속도가 균형을 이루게 되면, 상기 양극 금속 표면에 10~150nm의 직경을 갖는 다수의 기공이 형성된다. 기공이 생기게 되면, 전해액과 전류가 산화물 피막의 하부에 존재하는 금속 기질과 접촉할 수 있게 되며, 그 결과 자발적인 금속의 산화 반응에 의해 형성되는 산화물 피막보다 월등히 두꺼운 피막이 형성될 수 있게 된다. 이러한 과정을 거쳐 형성되는 피막은 그 공정 조건에 따라 여러 가지 물성을 지니는데 낮은 농도의 전해액과 높은 크기의 전류 또는 전압을 이용할수록 두꺼운 피막이 형성되게 된다. 상기와 같은 방법으로 형성되는 산화물 피막을 필터부(210)의 무기 피막으로 사용할 수 있다.When a direct current flows through the electrolyte, hydrogen is generated in the cathode metal and oxygen is produced in the anode metal (metals such as aluminum (Al) alloy, titanium (Ti), zinc (Zn), magnesium (Mg) and niobium (Nb)). In this case, the formed oxygen reacts with the anode metal to form a metal oxide film. In this process, the electrolyte dissolves the resulting oxide film finely. At this time, when the dissolution rate and the formation rate of the oxide film are balanced, a plurality of pores having a diameter of 10 to 150 nm are formed on the surface of the anode metal. do. When the pores are formed, the electrolyte and the current can be brought into contact with the metal substrate existing under the oxide film, and as a result, a film thicker than the oxide film formed by the spontaneous metal oxidation can be formed. The film formed through such a process has various properties depending on the process conditions. The thicker the film is formed by using a low concentration of electrolyte and a high current or voltage. The oxide film formed by the above method may be used as the inorganic film of the filter unit 210.
더욱 구체적으로 설명하자면, 무기 피막은 전도성 금속을 이용하여 제조될 수 있는데, 전도성 금속의 일례로는 알루미늄이 있다. 알루미늄을 양극으로 하여 양극 산화 반응을 일으키면 산화 알루미늄인 알루미나가 서서히 적층되고, 이렇게 형성된 알루미나 피막이 본 발명의 무기 피막으로 이용될 수 있다. 이후 무기 피막의 기공 사이에는 백금(Pt) 또는 로듐(Rh) 등과 같은 촉매층이 삽입될 수 있다. 상기 촉매층은 촉매 모액을 담지시켜 촉매층을 형성한 후 건조시켜 완성된다.More specifically, the inorganic coating may be manufactured using a conductive metal, an example of which is aluminum. When anodization reaction is performed using aluminum as the anode, alumina, which is aluminum oxide, is gradually laminated, and the alumina film thus formed can be used as the inorganic coating of the present invention. Thereafter, a catalyst layer such as platinum (Pt) or rhodium (Rh) may be inserted between the pores of the inorganic film. The catalyst layer is completed by supporting the catalyst mother liquid to form a catalyst layer and drying.
도 3을 참조하면, 필터부(210)의 베이스가 되는 금속층(11)과 상기 금속층(11) 위에 상기 금속층(11)을 구성하는 금속과 상기 금속의 산화물이 공존하는 전이층(12) 및 상기 전이층(12) 위에 형성되는 무기 피막(13)이 형성된 구조의 단면이 나타난다. 무기 피막(13)에 포함된 다수의 기공에는 촉매층의 일례로서 백금(Pt)이 형성된 모습을 볼 수 있다.Referring to FIG. 3, the metal layer 11 serving as the base of the filter unit 210, the transition layer 12 in which the metal constituting the metal layer 11 and the oxide of the metal coexist on the metal layer 11, and the The cross section of the structure in which the inorganic film 13 formed on the transition layer 12 is formed is shown. A plurality of pores included in the inorganic coating 13 can be seen to form platinum (Pt) as an example of the catalyst layer.
필터부(210)가 200~250℃로 가열된 상태에서 공기가 통과하면, 공기 중에 포함된 휘발성 유기물질이나 포름알데히드 같은 환경호르몬이 필터부(210)의 촉매층과 촉매 반응을 일으켜 인체에 무해한 이산화탄소와 물로 변화된다. 그리고 곰팡이나 포자 등 생화학적 오염물질도 촉매 반응에 의해 화학 연소되어 제거된다. 또한 일산화탄소와 일산화질소 등 독성 물질도 촉매 반응에 의해 이산화탄소, 질소와 물로 변화된다. When air passes while the filter unit 210 is heated to 200 to 250 ° C., environmental hormones such as volatile organic substances or formaldehyde contained in the air cause a catalytic reaction with the catalyst layer of the filter unit 210 and thus harmless carbon dioxide. And water. Biochemical contaminants such as mold and spores are also chemically burned and removed by catalytic reaction. In addition, toxic substances such as carbon monoxide and nitrogen monoxide are also converted into carbon dioxide, nitrogen and water by a catalytic reaction.
한편 상술한 바와 같이 히터(220)로 필터부(210)를 가열하여 공기를 통과시키게 되면 고온의 공기가 직접 공기배출구(300)로 나오게 된다. 고온의 정화된 공기를 외부온도에 가깝게 냉각시켜서 배출할 수 있다면 소비자들의 사용 만족도를 높일 수 있을 것이다. 이를 위해서는 공기정화모듈(200)에 열교환기(230)를 더 포함할 수도 있다.Meanwhile, as described above, when the filter unit 210 is heated by the heater 220 and air is passed through, the hot air comes directly to the air outlet 300. If the high-temperature purified air can be discharged by cooling it close to the outside temperature, it will increase the customer satisfaction. To this end, the air purification module 200 may further include a heat exchanger 230.
도 4를 참조하면, 공기정화모듈(200)에 열교환기(230)를 포함시킨 본 발명의 일 실시예가 제공된다. 열교환기(230)에서는 필터부(210)를 통과하기 전의 공기가 필터부(210)를 통과한 후의 공기와 열교환이 일어나게 된다. 이로 인해 고온의 정화된 공기는 냉각되고 정화 전의 공기는 가열된다. 정화된 공기는 온도가 떨어져서 배출되고, 정화 전의 공기는 가열된 상태에서 필터를 통과하기 때문에 촉매 반응이 더욱 잘 일어나는 효과가 있다.4, an embodiment of the present invention including the heat exchanger 230 in the air purification module 200 is provided. In the heat exchanger 230, the air before passing through the filter unit 210 may exchange heat with the air after passing through the filter unit 210. This cools the hot purified air and heats the air before purification. The purified air is discharged due to the drop in temperature, and since the air before purification passes through the filter in a heated state, the catalytic reaction is more effective.
도 5를 참조하면, 이러한 역할을 수행하는 열교환기(230)의 구조가 제공된다. 열교환기(230)는 종방향으로 관통 형성된 다수의 제1 슬롯(231)과, 상기 다수의 제1 슬롯(231) 사이마다 횡방향으로 관통 형성된 다수의 제2 슬롯(232)을 포함한다. 한편 종방향과 횡방향이라는 표현은 절대적 기준에 대한 종방향과 횡방향을 의미하는 것이 아니라, 각각에 대한 상대적인 기준을 표현하는 것이다. 상기 제1 또는 제2 슬롯(232) 중 어느 한 슬롯은 상기 필터부(210)를 통과한 후의 공기를 냉각하고, 다른 한 슬롯은 상기 필터부(210)를 통과하기 전의 공기를 가열하게 된다.Referring to FIG. 5, a structure of a heat exchanger 230 that performs this role is provided. The heat exchanger 230 includes a plurality of first slots 231 formed in the longitudinal direction and a plurality of second slots 232 formed in the transverse direction between the plurality of first slots 231. On the other hand, the expressions of longitudinal and transverse directions do not mean longitudinal and transverse directions for absolute standards, but express relative criteria for each. One of the first or second slots 232 cools the air after passing through the filter unit 210, and the other slot heats the air before passing through the filter unit 210.
예를 들어 제2 슬롯(232)을 통과하는 공기가 고온의 공기이고 제1 슬롯(231)을 통과하는 공기가 저온의 공기라면, 제2 슬롯(232)을 통과하는 공기가 열교환기(230)에 열을 전달하게 되고, 전달된 열은 제1 슬롯(231)을 통과하는 저온의 공기에 전해지게 된다. 따라서 제1 슬롯(231)을 통과하는 공기는 가열되는 효과가 있고, 제2 슬롯(232)을 통과하는 공기는 냉각되는 효과가 있다.For example, if the air passing through the second slot 232 is hot air and the air passing through the first slot 231 is cold air, the air passing through the second slot 232 is the heat exchanger 230. Heat is transmitted to the heat, which is transferred to the low-temperature air passing through the first slot 231. Therefore, the air passing through the first slot 231 is heated, and the air passing through the second slot 232 is cooled.
도 6을 참조하면, 공기정화모듈(200)을 통과한 고온의 정화된 공기를 외부공기와 혼합하여 공기배출구(300)를 통해 배출할 수 있도록 외부공기의 순환을 유도하는 외부공기순환유도용 팬(600)을 더 포함하는 본 발명의 다른 일 실시예가 제공된다. 공기정화모듈(200)은 200~250℃로 유지되면서 촉매반응을 일으키기 때문에 공기정화모듈(200)을 통과한 공기가 열교환기(230)를 통과하여 배출된다 하더라도 온도가 상온에 비해서는 높을 수밖에 없다. 공기배출구(300)로 배출되는 공기를 상온에 가까운 온도로 배출하는 효과를 누리기 위해서는 공기정화모듈(200)을 통과하지 않은 공기와 혼합하여 배출하는 것이 한가지 방법이 될 수 있다. 따라서 본 발명의 일 실시예에 따르면, 도 6에서 도시한 바와 같이 공기유입구(100)를 통과한 공기 중 일부는 공기정화모듈(200)로 들어가게 하고 나머지 일부는 외부공기순환용 팬 쪽으로 빠져나가게 하여 사용자의 만족도를 높일 수 있게 된다.Referring to Figure 6, the outside air circulation induction fan to induce the circulation of the outside air to be discharged through the air outlet 300 by mixing the high-temperature purified air passed through the air purification module 200 with the outside air Another embodiment of the present invention is further provided comprising 600. Since the air purification module 200 generates a catalytic reaction while being maintained at 200 to 250 ° C., even though the air passing through the air purification module 200 is discharged through the heat exchanger 230, the temperature is inevitably higher than the room temperature. . In order to enjoy the effect of discharging the air discharged to the air outlet 300 at a temperature close to room temperature, the mixed with the air that has not passed through the air purification module 200 may be discharged. Therefore, according to an embodiment of the present invention, as shown in FIG. 6, some of the air passing through the air inlet 100 enters the air purification module 200, and the other part exits to the external air circulation fan. The user's satisfaction can be improved.
도 7을 참조하면 통기유도용 팬(400)과 외부공기순환유도용 팬(600)을 모두 포함하여 구성된 공기 정화 장치의 내부 부품 조립 상태를 확인할 수 있다. 도 8은 도 7에 도시된 공기 정화 장치의 내부 부품 조립 상태를 베이스 케이스(700)와 결합하는 방법을 나타낸 도면이다.Referring to FIG. 7, the assembly state of the internal parts of the air purifying apparatus including both the ventilation guide fan 400 and the external air circulation guide fan 600 may be confirmed. FIG. 8 is a view illustrating a method of assembling the internal part assembly state of the air purification apparatus illustrated in FIG. 7 with the base case 700.
도 9는 도 8과 같은 방법으로 결합된 상태의 내부 단면을 더욱 상세히 설명하기 위해 제공되는 도면이다. 도 9에서 화살표는 공기가 흘러가는 방향을 의미한다. 도 9에 따르면 공기정화모듈(200)을 통과한 공기가 에어덕트(410)를 지나쳐셔 통기유도용 팬(400)으로 배출되도록 통기 경로가 제공되고, 공기정화모듈(200)을 통과하지 않고 외부공기순환유도용 팬(600)으로 공기가 지나가는 통기 경로가 제공될 수 있다. 다시 말해 공기유입구(100)로 들어온 공기가 분기지점(21)에 도달하면 공기의 일부는 열교환기(230) 방향으로 들어가게 되고 나머지 일부는 상측으로 올라가서 외부공기순환유도용 팬(600)으로 들어간다. 열교환기(230) 방향으로 들어가게 된 공기는 열교환기(230)를 종방향으로 지나 필터부(210)를 통과하게 된다. 도 9에서는 도 2에 도시한 필터판(211)과 히터(220)를 결합한 형태가 옆으로 눕혀진 형태로 도시되어 있다. 필터판(211)을 지나면서 촉매 반응에 의해 살균 및 정화된 공기는 다시 열교환기(230)를 횡방향으로 지나가게 된다. 그 후 공기는 에어덕트(410)를 통과하여 통기유도용 팬(400)을 지나 공기배출구(300)로 빠져나가게 된다. 통기유도용 팬(400)을 지난 공기는 외부공기순환유도용 팬(600)을 통과한 공기와 혼합되어 공기배출구(300)로 나가게 된다. 통기유도용 팬(400)과 외부공기순환유도용 팬(600)이 공기를 측방향에서 유입시켜 상방으로 배출하도록 구성되면 용이하게 공기를 혼합할 수 있다.9 is a view provided to explain in more detail the internal cross-section of the coupled state in the same manner as in FIG. In FIG. 9, an arrow means a direction in which air flows. According to FIG. 9, a ventilation path is provided such that air passing through the air purification module 200 passes through the air duct 410 to be discharged to the ventilation guide fan 400, and does not pass through the air purification module 200. A ventilation path through which air passes may be provided to the air circulation induction fan 600. In other words, when the air entering the air inlet 100 reaches the branch point 21, part of the air enters the heat exchanger 230 direction, and the other part goes up and enters the external air circulation induction fan 600. Air entering the heat exchanger 230 passes through the heat exchanger 230 in the longitudinal direction and passes through the filter unit 210. In FIG. 9, the shape in which the filter plate 211 and the heater 220 shown in FIG. 2 are coupled to each other is shown in a side-down form. The air sterilized and purified by the catalytic reaction while passing through the filter plate 211 passes through the heat exchanger 230 laterally. Thereafter, the air passes through the air duct 410 and passes through the air inlet fan 400 to the air outlet 300. The air passing through the induction guide fan 400 is mixed with the air passing through the external air circulation guide fan 600 and exits to the air outlet 300. If the ventilation guide fan 400 and the external air circulating induction fan 600 is configured to inject air from the side direction and discharge upward, air can be easily mixed.
도 10에 도시된 바와 같이 본 발명의 또 다른 일 실시예에 의하면 공기배출구(300)를 개폐할 수 있도록 구성되는 커버부(800)가 더 포함될 수 있다. 커버부(800)는 공기 정화 장치가 가동중에는 공기배출구(300)를 개방하여 정화된 공기가 공기배출구(300)를 통해 배출되도록 하고 가동을 멈추면 공기배출구(300)를 폐쇄하도록 한다. 도 10을 참조하면, 커버부(800)는 외주를 따라 슬라이딩 서포트(810)가 연결되고 슬라이딩 서포트(810)가 상하 방향으로 이동함으로써 커버부(800)가 개폐되도록 구성된다.According to another embodiment of the present invention as shown in Figure 10 may further include a cover portion 800 configured to open and close the air outlet (300). The cover 800 allows the purified air to be discharged through the air outlet 300 by opening the air outlet 300 while the air cleaner is in operation, and closes the air outlet 300 when the operation stops. Referring to FIG. 10, the cover part 800 is configured such that the sliding support 810 is connected along the outer circumference, and the cover part 800 is opened and closed by moving the sliding support 810 in the vertical direction.
또한 커버부(800)에는 엘이디모듈(820)을 더 포함할 수 있는데, 엘이디모듈(820)은 서로 다른 색깔의 2개의 엘이디를 포함할 수도 있다. 예를 들어 파란색과 빨간색 엘이디를 사용할 경우 오염도가 높으면 빨간색만 점등하고 오염도가 낮으면 파란색만 점등하여 주변 오염도를 표시해 줄 수 있다. 오염도가 중간이면 2개의 엘이디를 모두 점등하여 주변 오염도를 표시할 수도 있다. 주변의 오염도를 조사하기 위해 먼지센서나 가스센서를 더 포함할 수도 있다. 엘이디모듈(820), 먼지센서, 가스센서는 제어부(500)와 연결되어 제어부(500)에 의해 제어될 수 있다.In addition, the cover unit 800 may further include an LED module 820. The LED module 820 may include two LEDs of different colors. For example, if blue and red LEDs are used, only the red one lights up when the pollution level is high, and only the blue light is displayed when the pollution level is low. If the pollution level is medium, both LEDs may be lit to indicate the ambient pollution level. It may further include a dust sensor or a gas sensor to investigate the degree of pollution around. The LED module 820, the dust sensor, and the gas sensor may be connected to the control unit 500 and controlled by the control unit 500.
또한 본 발명의 공기 정화 장치를 제어하기 위한 입력 신호를 사용자가 인가하기 위해서 터치패널(710)을 더 포함할 수 있다. 터치패널(710)는 제어부(500)와 연결되어 제어부(500)에 의해 제어될 수 있으며 터치패널(710)에 의해 다양한 구동 모드를 선택할 수도 있을 것이다.In addition, the touch panel 710 may further include a user for applying an input signal for controlling the air purifying apparatus of the present invention. The touch panel 710 may be connected to the controller 500 and controlled by the controller 500, and may select various driving modes by the touch panel 710.
또한 본 발명의 공기 정화 장치는 공기유입구(100) 주변에 프리필터를 더 포함할 수도 있다. 공기정화모듈(200)을 통과하기 전 공기 중의 분진은 프리필터에 의해 미리 여과된다. 프리필터는 부직포 소재로 구성하여 주기적으로 교환하여 사용할 수 있다.In addition, the air purifying apparatus of the present invention may further include a prefilter around the air inlet 100. Before passing through the air purification module 200, the dust in the air is pre-filtered by the pre-filter. The prefilter is composed of non-woven material and can be replaced periodically.
또한 본 발명의 공기 정화 장치는 조도센서를 더 포함할 수 있다. 조도센서는 주변의 조도를 측정하여 제어부(500)로 조도 값을 송신하는 센서이다. 조도센서를 구비하면 주야를 구분하여 공기 정화 장치의 작동을 제어하는 방법을 제공할 수 있다.In addition, the air purifying apparatus of the present invention may further include an illuminance sensor. The illuminance sensor measures a peripheral illuminance and transmits an illuminance value to the controller 500. Having an illuminance sensor can provide a method of controlling the operation of the air purification device by dividing the day and night.
이하, 도 11을 참조하여 야간에 공기 정화 장치의 작동을 자동으로 제어하는 방법을 설명한다. 조도센서가 먼저 공기 정화 장치의 주변 조도를 측정한다.(S11) 조도센서는 제어부(500)와 연결되어 신호를 송신할 수 있는데 조도센서에서 측정된 조도 값은 제어부(500)로 송신하게 된다.(S12) 제어부(500)는 조도센서로부터 수신한 조도 값을 소정의 기준 값과 비교하는데(S13) 조도 값이 소정의 기준 값 이하로 떨어지면 야간이 되었다는 것을 알 수 있다. 야간에는 통기유도용 팬(400)의 회전 소음을 줄이기 위해 통기유도용 팬(400)의 회전 속도를 감소시켜야 한다. 따라서 제어부(500)가 통기유도용 팬(400)으로 신호를 송신하여 회전 속도를 감소시킨다.(S14) 만약 외부공기순환유도용 팬(600)도 함께 사용하는 경우라면 외부공기순환유도용 팬(600)의 회전 속도도 감소시킬 수 있을 것이다.Hereinafter, a method of automatically controlling the operation of the air purifying device at night will be described with reference to FIG. 11. The illuminance sensor first measures the ambient illuminance of the air purification device (S11). The illuminance sensor may be connected to the control unit 500 to transmit a signal, and the illuminance value measured by the illuminance sensor is transmitted to the control unit 500. The control unit 500 compares the illuminance value received from the illuminance sensor with a predetermined reference value (S13). When the illuminance value falls below the predetermined reference value, the controller 500 may know that it is at night. At night, the rotational speed of the ventilation guide fan 400 should be reduced to reduce the rotation noise of the ventilation guide fan 400. Therefore, the control unit 500 reduces the rotation speed by transmitting a signal to the induction fan 400. (S14) If the external air circulation induction fan 600 is also used together, the external air circulation induction fan ( The rotation speed of 600 may also be reduced.
한편 본 발명의 공기 정화 장치는 온도센서를 더 포함할 수 있다. 온도센서는 공기 정화 장치 내부의 온도를 측정하여 제어부(500)로 온도 값을 송신하는 센서이다. 온도센서를 구비하면 히터(220)에 의해 과열되는 것을 방지할 수 있고, 필터부(210)의 온도를 200~250℃로 유지시켜 촉매 반응이 원활히 일어나게 할 수 있다.Meanwhile, the air purification device of the present invention may further include a temperature sensor. The temperature sensor is a sensor that measures a temperature inside the air purifier and transmits a temperature value to the controller 500. The temperature sensor may be prevented from being overheated by the heater 220, and the catalyst reaction may be smoothly maintained by maintaining the temperature of the filter unit 210 at 200 to 250 ° C.
이하, 도 12를 참조하여 필터부(210)의 온도를 자동으로 제어하는 방법을 설명한다. 온도센서가 먼저 공기 정화 장치의 내부 온도를 측정한다.(S21) 온도센서는 에어덕트(410)에 설치될 수도 있고 히터(220)에 설치될 수도 있을 것이다. 또는 필터부(210)에 직접 설치될 수도 있을 것이다. 온도센서는 제어부(500)와 연결되어 신호를 송신할 수 있는데 온도센서에서 측정된 온도 값은 제어부(500)로 송신하게 된다.(S22) 제어부(500)는 온도센서로부터 수신한 온도 값을 소정의 기준 값과 비교하는데(S23) 온도 값이 소정의 기준 값 이상으로 올라가면 과열되었다는 것을 알 수 있다. 여기서 소정의 기준 값은 온도센서가 설치된 위치에 따라 달리 설정할 수 있을 것이다. 바람직하게는 필터부(210)의 온도가 250℃를 넘는 지점에서의 온도 센서에서 측정되는 상대적인 온도 값을 기준 값으로 설정할 수 있을 것이다. 온도 값이 소정의 기준 값 이상이 되었다고 판단되면 제어부(500)가 히터(220) 작동을 정지시킨다.(S24) 히터(220)의 작동을 소정의 시간을 두고 일시적으로만 정지시킬 수도 있을 것이다. 일시 정지 후에는 다시 히터(220)가 작동하여 식혀진 필터부(210)를 재가열하게 될 것이다. 이처럼 온도를 자동으로 제어하는 방법에 의하면 필터부(210)의 온도를 소정의 범위, 바람직하게는 200~250℃로 유지할 수 있는 장점이 있다.Hereinafter, a method of automatically controlling the temperature of the filter unit 210 will be described with reference to FIG. 12. The temperature sensor first measures the internal temperature of the air purifier (S21). The temperature sensor may be installed in the air duct 410 or may be installed in the heater 220. Alternatively, the filter unit 210 may be installed directly. The temperature sensor may be connected to the control unit 500 to transmit a signal, and the temperature value measured by the temperature sensor is transmitted to the control unit 500. (S22) The control unit 500 determines a temperature value received from the temperature sensor. Compared with the reference value of (S23) it can be seen that if the temperature value rises above the predetermined reference value, it is overheated. Here, the predetermined reference value may be set differently according to the position where the temperature sensor is installed. Preferably, the relative temperature value measured by the temperature sensor at the point where the temperature of the filter unit 210 exceeds 250 ° C. may be set as a reference value. If it is determined that the temperature value is equal to or greater than a predetermined reference value, the controller 500 stops the operation of the heater 220. (S24) The operation of the heater 220 may be temporarily stopped only for a predetermined time. After the pause, the heater 220 will operate again to reheat the cooled filter unit 210. As such, the method of automatically controlling the temperature has an advantage of maintaining the temperature of the filter unit 210 in a predetermined range, preferably, 200 to 250 ° C.
