It can raise the use environment even higher.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

도 3은 본 발명에 따른 가습 공기청정기의 분해사시도이고, 도 4는 본 발명에 따른 가습 공기청정기의 조립상태 사시도이다.Figure 3 is an exploded perspective view of the humidifying air cleaner according to the present invention, Figure 4 is an assembled perspective view of the humidifying air cleaner according to the present invention.

도 3 및 도 4에 도시된 바와 같이, 본 발명에 따른 가습 공기청정기는 본체(100)와 상부케이스(200)를 포함하여 이루어져 상부에 흡입구를 형성하고 측부에 토출구를 형성하는 바디조립체와, 상기 바디조립체의 하부에 구비되어 일정량의 물을 저장하는 수조(300)로 구성된다.As shown in Figure 3 and 4, the humidifying air purifier according to the present invention comprises a body assembly which comprises a main body 100 and the upper case 200 to form an intake port on the top and the discharge port on the side, and It is provided in the lower portion of the body assembly consists of a water tank 300 for storing a certain amount of water.

이때, 상기 본체(100)는 가습 공기청정기의 주된 구성 부위로, 상하면은 개구되고, 테두리를 따라 그릴 형상의 토출구(110)가 형성된다.At this time, the main body 100 is a main constituent part of the humidified air purifier, the upper and lower surfaces are opened, the discharge port 110 of the grill shape is formed along the rim.

또한, 상기 본체(100) 내부에는 송풍팬(170)이 설치되는데, 상기 송풍팬(170)은 본체(100)의 상부에 형성된 브라켓(120)에 안착되어 상기 본체(100)의 개방된 상면을 커버하는 상부케이스(200)의 흡입구(210)를 통해 외기를 흡입하게 된다.In addition, a blowing fan 170 is installed inside the main body 100, and the blowing fan 170 is seated on a bracket 120 formed on an upper part of the main body 100 to open an upper surface of the main body 100. The outside air is sucked through the suction port 210 of the upper case 200 to cover.

아울러, 상기 상부케이스(200)의 일측면에는 상기 송풍팬(170)의 회동을 조작 제어하는 조절노브(230)가 더 구비된다.In addition, one side of the upper case 200 is further provided with a control knob 230 for controlling the rotation of the blowing fan 170.

한편, 상기 본체(200)의 하부에는 수조(300)가 구비되며, 상기 수조(300)에는 물이 채워진다.Meanwhile, a water tank 300 is provided below the main body 200, and water is filled in the water tank 300.

또한, 상기 수조(300)에는 구동모터(미도시)에 의해 회전되는 디스크조립체(350)가 설치된다.In addition, the water tank 300 is provided with a disk assembly 350 that is rotated by a drive motor (not shown).

상기 디스크조립체(350)는 회전축(360)에 의해 회전가능하게 고정되는 다수의 디스크(370)를 포함하며, 회전축(360)에 회전 가능하게 설치되는 이동레버(380)를 포함하고, 디스크(370)의 일부가 물 속에 잠기도록 배치된다.The disk assembly 350 includes a plurality of disks 370 rotatably fixed by the rotation shaft 360, and includes a moving lever 380 rotatably installed on the rotation shaft 360, and the disk 370. Part of the) is arranged to be submerged in water.

아울러, 상기 회전축(360)은 한 쌍의 제1,2지지부(310,320)의 상부에 형성된 안착홈(340)에 안착 지지되며, 이들 제1,2지지부(310,320)는 지지부(330)를 구성한다.In addition, the rotation shaft 360 is seated and supported in the mounting groove 340 formed on the pair of first and second support parts 310 and 320, and the first and second support parts 310 and 320 constitute the support part 330. .

그리고, 수조(300)의 저면 모서리 부근에는 내부를 향해 함몰 형성되는 손잡이(390)가 형성되어 가습 공기청정기를 이동시킬 때 용이하게 사용된다.And, near the bottom edge of the water tank 300, the handle 390 is formed to be recessed toward the inside is easily used when moving the humidified air cleaner.

한편, 상기 본체(100)의 상부, 즉 상부케이스(230)와 인접한 송풍팬(170)의 하방에는 최대한 흡입구(210)에 가깝게 플라즈마발생기(400)가 설치된다.On the other hand, the plasma generator 400 is installed in the upper portion of the main body 100, that is, the lower side of the blowing fan 170 adjacent to the upper case 230 as close to the suction port 210 as much as possible.

상기 플라즈마발생기(400)는 대기압 하에서 플라즈마를 발생시키는 대기압 플라즈마발생기로서, 일종의 글로우방전 형태라고 볼 수 있다.The plasma generator 400 is an atmospheric pressure plasma generator that generates plasma under atmospheric pressure, and may be regarded as a type of glow discharge.

이러한 플라즈마발생기(400)로부터 발생된 플라즈마는 외부공기가 송풍 팬(170)의 흡입력을 통해 흡입구(210)로 유입되는 순간부터 살균처리하기 때문에 외부공기 유입, 내부순환, 토출구(110)로 토출되기까지 기존에 비해 상대적으로 긴 시간동안 플라즈마 처리(수소 양이온과 산소 음이온에 의한 유해물질 분해)가 이루어지게 된다.Since the plasma generated from the plasma generator 400 is sterilized from the moment when the external air flows into the suction port 210 through the suction force of the blower fan 170, the external air is discharged into the internal air, the internal circulation, and the discharge port 110. Until now, plasma treatment (decomposition of harmful substances by hydrogen cations and oxygen anions) is performed for a relatively long time.

이로 인해 살균효율이 높아져 공기 정화기능이 기존대비 월등이 향상된다.As a result, the sterilization efficiency is increased, and the air purification function is improved.

나아가, 광촉매 활성화를 높이고 살균효율을 더욱 극대화시키기 위해 본체(100) 내부에 자외선램프(미도시)를 더 설치할 수 있다.Furthermore, an ultraviolet lamp (not shown) may be further installed inside the main body 100 to increase photocatalyst activation and further maximize sterilization efficiency.

이때, 자외선램프는 180~400nm 파장대역, 특히 253.7nm의 파장의 살균선을 방사하는 것이 바람직한데, 이는 대장균, 박테리아 등의 DNA를 손상시켜 외부공기에 포함된 세균들을 살균시키기에 가장 적당하기 때문이다.In this case, it is preferable that the ultraviolet lamp emits sterilizing rays having a wavelength range of 180 to 400 nm, particularly 253.7 nm, because it is most suitable for sterilizing bacteria contained in external air by damaging DNA such as E. coli and bacteria. .

뿐만 아니라, 살균 효율을 더욱 높이기 위하여 상기 송풍팬(170)이 설치된 주변 또는 상기 본체(100)의 내벽에는 상기 자외선램프로부터 발생되는 자외선에 의해 광산화반응을 일으키는 광촉매, 바람직하기로는 이산화티탄이 코팅되도록 구성할 수 있다.In addition, in order to further increase sterilization efficiency, a photocatalyst, preferably titanium dioxide, is coated on the periphery of the blowing fan 170 or the inner wall of the main body 100 to cause a photooxidation reaction by ultraviolet light generated from the ultraviolet lamp. Can be configured.

특히, 이산화티탄은 전이금속이 함유된 아나타제(ANATASE) 형태가 바람직하며, 전구체인 Ti Alcoxide sol로부터 만드는 sol-gel법 혹은 TiO2와 SiO2 복합산화물을 제조하는 형태인 고체산법에 의해 제조됨이 특히 바람직하다.Particularly, titanium dioxide is preferably in the form of an anatase containing a transition metal, and the sol-gel method or TiO 2 and SiO 2 made from Ti Alcoxide sol as a precursor. It is especially preferable that it is manufactured by the solid acid method which is a form which produces a composite oxide.

그리하여, 전원 공급에 따라 송풍팬(170)이 회전하면서 외기를 흡입하고, 디스크(370)가 회전되면서 수조(300) 내에 저장된 물에 적셔지고, 흡입구(210)를 통 해 유입된 외기와 접촉하며, 외기에 포함된 이물질 또는 불순물은 물에 적은 디스크(370)에 의해 제거되고 외기는 습기를 포함하게 되고, 습기가 포함된 외기는 토출구(110)를 통해 배출됨으로써 가습 공기청정기가 설치된 실내의 공기청정 및 가습이 이루어진다.Thus, the blowing fan 170 rotates to suck the outside air according to the power supply, and the disk 370 rotates to soak in the water stored in the water tank 300, and to contact the outside air introduced through the suction port 210. , The foreign matter or impurities contained in the outside air is removed by the disk 370 less in the water and the outside air contains moisture, the outdoor air containing the moisture is discharged through the discharge port 110, the air in the room installed humidifier air purifier Purification and humidification are achieved.

이때, 공기의 유동은 흡입구(210)로 흡입 → 본체(100) 내부 순환, 열교환 → 토출구(110)로 토출과 같이 이루어지는데, 이 과정 전체에 걸쳐 플라즈마 처리가 이루어지게 된다.At this time, the flow of air is performed as the suction → the main body 100 in the circulation, the heat exchange → discharge to the discharge port 110, such as the plasma treatment is performed throughout this process.

특히, 자외선램프와 광촉매를 더 구비한 경우라면, 자외선램프로부터 방사된 253.7nm의 파장에 의해 광활성화된 광촉매가 광산화작용을 통해 살균 및 악취, 유기물분해, 음이온발생 등을 더욱 촉진하게 된다.In particular, when the UV lamp and the photocatalyst are further provided, the photocatalyst photoactivated by the wavelength of 253.7 nm emitted from the ultraviolet lamp further promotes sterilization and odor, organic decomposition, and anion generation through photooxidation.

이때, 자외선램프로부터 조사되는 살균선(자외선)에 의해 광촉매에서는 전하-양공이 형성되게 되는데, 이 두가지 물질들은 재결합하거나 또는 흡착물질들과 반응할 수 있는 표면으로 이동하면서 양공이나 전자는 다음의 3가지 반응중 한가지를 통해 소멸하게 된다.At this time, charge-holes are formed in the photocatalyst by germicidal rays (ultraviolet rays) irradiated from ultraviolet lamps.The two materials move to the surface where they can recombine or react with adsorbents, It disappears through one of the reactions.

첫째, 광촉매 반응으로 다음과 같다.First, the photocatalytic reaction is as follows.

Aad(흡착물질 A) + h+ →(Aad)+ Aad (adsorbent A) + h + → (Aad) +

Bad(흡착물질 B) + ecb - →(Bad)- Bad (adsorbent B) + e cb - → ( Bad) -

(Aad)+ + (Bad)- → 생성물(Aad) + + (Bad) - → product

이 반응에 있어서는 생성된 양공과 전자가 최종적으로 다시 결합하는 경우이지만 이미 흡수된 빛에너지는 반응의 활성화에너지를 공급하는데 사용된 것이다.In this reaction, the generated holes and electrons finally recombine, but the light energy already absorbed is used to supply the activation energy of the reaction.

둘째, 격자의 변화 반응이다.Second is the change response of the lattice.

h+ + 격자 →(격자)+ h + + grid → (grid) +

(격자)+ →격자반응 생성물(Grid) + → lattice reaction products

'격자 변화 반응' 의 경우를 보면 반응에 사용된 반도체는 자신이 반응의 진행에 따라 변화를 일으키게 된다. 그리고 반응에 사용된 반도체는 변화하지 않은 상태로 있게 된다.In the case of the 'grid change reaction', the semiconductor used in the reaction changes as the reaction proceeds. The semiconductor used in the reaction remains unchanged.

세째, 전자와 양공의 재결합 반응이다.Third is the recombination reaction of electrons and holes.

h+ + ecb - →열에너지h + + e cb - → heat

'전자와 양공의 재결합 반응' 은 생성된 양공과 전자가 광촉매 산화반응에 참여하지 않고 직접 재결합하는 경우이다.The recombination reaction between electrons and holes is a case where the generated holes and electrons recombine directly without participating in the photocatalytic oxidation reaction.

따라서, 공간 전하층에서 전자대의 휨은 생성된 양공과 전자가 서로 반대 방향으로 움직이게 함으로서 궁극적으로 전자와 양공의 재결합을 방지하는 효과를 나타내게 되는 것이다.Therefore, the bending of the electron band in the space charge layer causes the generated holes and electrons to move in opposite directions, thereby ultimately preventing the recombination of the electrons and the holes.

이러한 반응들에 의해 유기물질이 산화되면서 최종적으로 분해처리되게 되는 것이다.By these reactions, the organic material is oxidized and finally decomposed.
