상기와 같은 구성으로 이루어지는 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the configuration as described above are as follows.

도 4는 본 고안에 따른 공기정화기능을 구비한 환기장치의 사용상태단면도를 나타내는 것이다.Figure 4 shows a cross-sectional view of the use state of the ventilation device with an air purifying function according to the present invention.

전원이 인가되면 본체부(110)에 구비된 흡기팬(112)과 배기팬(115)이 회전하게 된다.When power is applied, the intake fan 112 and the exhaust fan 115 provided in the main body 110 rotate.

상기한 흡기팬(112)이 작동하게 되면, 실외흡입공(116a)으로 유입되어 실외흡입실(160)에 있던 실외공기는 열교환기(120)를 지나면서 열교환이 이루어진 후에, 실내배출실(113)로 이동된다.When the intake fan 112 is operated, the outdoor air flows into the outdoor suction hole 116a and the outdoor air in the outdoor suction chamber 160 passes through the heat exchanger 120, and then heat exchanges. Is moved to.

이와 같이 실내배출실(113)로 이동된 공기는 실내배출실(113)에 구비된 오존발생기(130)와 음이온발생기(140)에서 발생되는 오존이나 음이온을 포함하여 실내로 삽입이 된다.As such, the air moved to the indoor discharge chamber 113 is inserted into the room including ozone or anion generated by the ozone generator 130 and the negative ion generator 140 provided in the indoor discharge chamber 113.

그러므로, 오존발생기(130)에서 발생되는 오존에 의하여 하여, 오존이 분해할 때 나오는 산소의 산화 작용을 이용하여 냄세제거, 살균, 소독과 공기의 정화 등이 이루어지게 되며, 음이온 발생기(140)에서 발생되는 음이온은 심신이 휴식을취할 수 있도록 부교감신경에 영향을 주어 기분을 안정시키고 몸을 진정하는 효과를 갖게 된다.Therefore, by the ozone generated by the ozone generator 130, by removing the ozone by using the oxidation of the oxygen released from the ozone deodorization, sterilization, disinfection and air purification, etc., in the negative ion generator 140 Negative ions are generated to affect the parasympathetic nerve so that the mind and body can rest, to stabilize the mood and calm the body.

즉, 공기 중에는 존재하는 여러 가지 오염물질 즉, 담배 연기, 아황산가스(SO2), 질소 산화물(NOx), 일산화탄소(CO) 및 각종 유기물질은 양이온을 형성하고 있는데 음이온은 이들 양이온에 흡착 침전되어 제거하므로 공기를 깨끗하고 신선하게 유지해 주는 공기정화작용, 양이온은 세균이나 먼지, 꽃가루 곰팡이, 오염된 입자들을 자유롭게 떠다니도록 해 공기를 혼탁하게 만들지만, 음이온은 이들을 중화, 제거해 주는 먼지제거 및 살균작용, 혈액의 정화작용, 세포의 활성작용, 저항력 증가작용, 통증완화 작용등이 이루어지게 된다.That is, various pollutants present in the air, such as tobacco smoke, sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), and various organic substances, form cations. Anions are adsorbed and precipitated on these cations to remove them. Air purification to keep the air clean and fresh, and the cation frees bacteria, dust, pollen mold, and contaminated particles to make the air cloudy, while negative ions remove and sterilize the dust to neutralize and remove them. , Blood purification, cell activation, resistance increase, pain relief will be made.

이상에서 설명한 바와 같이 본 고안은 실내배출실에 오존발생기와 음이온발생기를 구비하여 오존과 음이온이 실내로 삽입되는 공기와 같이 포함되어 삽입이 이루어지도록 하여 세균이나 아주 미세한 먼지를 제거하는 효과를 갖는다.As described above, the present invention includes an ozone generator and an anion generator in an indoor discharge chamber, so that ozone and negative ions are included together with the air inserted into the room to remove bacteria and very fine dust.

이상에서는 본 고안을 특정의 바람직한 실시예를 예를들어 도시하고 설명하였으나, 본 고안은 상기한 실시예에 한정되지 아니하며 본 고안의 정신을 벗어나지 않는 범위내에서 당해 고안 기술분야에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 가능할 것이다.In the above, the present invention has been illustrated and described by way of specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and those skilled in the art without departing from the spirit of the present invention. Various changes and modifications may be made by the user.
