Description

공기정화기용 전기집진유닛과 이를 이용한 공기정화기Electric dust collecting unit for air purifier and air purifier using same
본 발명은 공기정화기용 전기집진유닛과 이를 이용한 공기정화기에 관한 것으로서, 소형으로 이루어짐에도 불구하고 집진의 효율의 우수하고 안정적으로 작동할 수 있는 공기정화기용 전기집진유닛과 이를 이용한 소형 공기정화기에 관한 것이다.The present invention relates to an electric dust collecting unit for an air cleaner and an air purifier using the same, and more particularly, to an electric dust collecting unit for an air cleaner capable of stably operating with excellent dust collecting efficiency despite its small size and a small air purifier using the same will be.
현재 널리 사용되고 있는 공기정화장치는 크게 두 가지 방식으로 분류된다. 하나는 필터를 사용하는 방식이고 다른 하나는 대전된 집진판을 사용하는 방식이다.Currently widely used air purifiers are divided into two types. One is using a filter and the other is using a charged particle board.
필터를 사용하는 방식은 수많은 미세 구멍을 가지는 필터를 공기가 통과하도록 하여 공기 중의 오염물 입자가 필터의 미세 구멍에 걸리도록 함으로써 오염물 입자를 분리한다.The method of using a filter separates contaminant particles by allowing air to pass through a filter having numerous fine holes so that contaminant particles in the air are trapped in the fine holes of the filter.
그런데 필터를 사용하는 방식에서 공기정화의 효율을 높이기 위하여 필터의 구멍 크기를 매우 작게 하는 경우에는 공기정화장치 내로 공기를 흡입할 때 압력 손실이 증가하게 되어 전력 소모량이 커지고, 오염물 입자에 의해 오염된 필터를 수시로 세척하거나 교체해주어야 하므로 유지관리가 번거롭고 경제적이지 못하다.However, in the case of using a filter, if the hole size of the filter is made very small in order to improve the efficiency of air purification, the pressure loss increases when the air is sucked into the air purifying device, thereby increasing the power consumption. Since the filter must be cleaned or replaced from time to time, maintenance is troublesome and uneconomical.
전기집진식의 공기정화기는 공기 중의 오염물 입자를 이온으로 대전시킨 후 대전된 집진판 사이를 통과하도록 하여 오염물 입자가 이온과 함께 반대 극을 가지는 집진판에 부착되게 함으로써 오염물 입자를 제거한다.The air collecting type air purifier removes contaminant particles by causing contaminant particles in the air to be charged with ions and then passing between the charged collecting plates so that the contaminant particles adhere to the dust collecting plate having the opposite polarity together with the ions.
전기집진식 공기정화기에서 집진이 이루어지는 부분은 도 1에 도시되어 있는 것과 같이, 서로 다른 극으로 대전된 집진판(C1, C2)이 교대로 배치되어 형성된다. 그런데 어느 하나의 극으로 대전된 집진판(C1)의 말단부에서는 전하가 집중되고, 마찬가지로 전하가 집중되어 있는 다른 극의 집진판 말단부(C2)와 인접하기 때문에 다른 부분들에 비하여 상대적으로 방전 현상이 쉽게 발생하여 스파크가 일어날 수 있다.The dust collecting type air cleaner is formed by alternately arranging the dust collecting plates C1 and C2 charged with different polarities, as shown in Fig. However, since charges are concentrated at the ends of the dust collecting plate C1 charged by one of the poles and adjacent to the dust collecting plate end portions C2 of other poles in which charges are also concentrated, the discharge phenomenon occurs relatively easily So that sparks can occur.
종래에는 집진판 말단부에서 스파크가 발생하는 것을 방지하기 위하여 서로 다른 극의 집진판 말단부 사이에 집진판의 길이방향으로 이격을 두는 방법을 사용하였다.Conventionally, in order to prevent the spark from being generated at the end portion of the dust collecting plate, a method of keeping the dust collecting plate in the longitudinal direction is used between the end portions of the dust collecting plates of different polarities.
그러나 이러한 이격을 두는 경우 집진판을 배치하는 데 있어 공간의 효율성이 떨어져 동일한 크기의 공간 내에서 집진이 이루어지는 면적이 작아지게 되고, 이에 따라 집진의 효율이 떨어지게 된다.However, if such a gap is provided, the efficiency of space is reduced in arranging the dust collecting plate, the area of collecting dust in the same sized space becomes small, and the efficiency of dust collecting becomes low.
한편, 최근에는 미세먼지나 황사가 많이 발생하여 실내에서 환기를 자주 할 수 없기 때문에 가정이나 자동차에서 간편하게 사용할 수 있는 공기정화기에 대한 관심이 높아지고 있는데, 공기정화기의 큰 크기나 유지관리의 번거로움은 공기정화기의 사용을 저해하는 요인이 된다.In recent years, there has been a lot of fine dust and yellow dust in the room, so it is not possible to frequently ventilate the room. Therefore, there is a growing interest in air cleaners that can be easily used in homes and automobiles. It becomes a factor that hinders the use of the air purifier.
본 발명의 실시예들은 극판을 공간 효율적으로 배치하여 전기집진 방식의 공기정화기를 소형으로 형성할 수 있으면서도 서로 다른 극의 극판 사이에서 스파크가 발생하는 것을 방지할 수 있는 공기정화기용 전기집진유닛과 이를 이용한 공기정화기를 제공하고자 한다.The embodiments of the present invention are directed to an electrostatic precipitator for an air cleaner which can arrange electrode plates in a space-efficient manner to form a small air purifier of an electrostatic precipitator type, To provide a used air purifier.

That is, even if the air purifier of the electric dust collection system is made compact, it is possible to exhibit excellent dust collection efficiency.
본 발명에 의한 전기집진유닛(1)을 공기정화기에 장착하여 사용하는 경우, 제1,2 극판(20, 40)에서 지속적으로 집진이 이루어짐에 따라 제1, 2 극판(20, 40)에 먼지가 쌓여 집진의 효율의 저하될 수 있으므로, 일정 주기로 제1, 2 극판(20, 40)에서 먼지를 제거해줄 필요가 있다.When the electric dust collecting unit 1 according to the present invention is mounted on the air purifier and dust is continuously collected in the first and second electrode plates 20 and 40, It is necessary to remove dust from the first and second electrode plates 20 and 40 at regular intervals.

Further, even when a conductive material is coated on a nonconductive plastic plate, it is possible to exhibit an effect of preventing a discharge phenomenon or the like. In this case, the first electrode plate 20 and the second electrode plate 40 can be lightly formed The manufacturing cost can be reduced.
이하에서는 상기한 것과 같은 전기집진유닛(1)을 이용한 소형 공기정화기에 대하여 설명하도록 한다. 도 7에는 본 발명에 의한 소형 공기정화기의 개략적인 구성도가 도시되어 있다. 위에서 설명한 전기집진유닛(1)에 대해서는 중복되는 자세한 설명을 생략하기로 한다.Hereinafter, a small air purifier using the above-described electric dust collecting unit 1 will be described. Fig. 7 shows a schematic configuration diagram of a small-sized air purifier according to the present invention. The detailed description of the electric dust collecting unit 1 described above will be omitted.
본 발명의 일 실시예에 의한 소형 공기정화기는 이온발생유닛(2), 상기한 전기집진유닛(1) 및 팬(3)을 포함하여 이루어진다. The small air purifier according to the embodiment of the present invention comprises the ion generating unit 2, the above-mentioned electric dust collecting unit 1 and the fan 3. [
이온발생유닛(2)은 외부 전원에서 고전압을 인가받아 이온을 발생시킨다. 즉, 상기 이온발생유닛(2)은 고전압에 의하여 대전된 상태로 공기 중에 노출되게 형성되는 극을 구비하여 상기 극에서 방전 현상을 발생시킴으로써 극 주변으로 이온이 발생하도록 한다.The ion generating unit 2 generates ions by receiving a high voltage from an external power source. That is, the ion generating unit 2 has a pole formed to be exposed to the air in a charged state by a high voltage, thereby generating a discharge phenomenon in the pole so that ions are generated around the pole.
이온발생유닛(2)에 의해 발생된 이온은 공기 중으로 분산되고 분산된 이온은 먼지 입자를 하전시킨다.The ions generated by the ion generating unit 2 are dispersed in the air, and the dispersed ions charge the dust particles.
전기집진유닛(1)은 이처럼 이온에 의해 하전된 먼지 입자를 정전기적 인력에 의하여 집진한다.The electric dust collecting unit 1 collects the dust particles charged by the ions by the electrostatic attraction.
그리고 팬(3)은 공기가 이온발생유닛(2)과 전기집진유닛(1)을 통과하도록 공기를 이동시켜, 이온발생유닛(2)에서 발생한 이온과 공기 중의 먼지입자가 접촉할 수 있도록 하고 하전된 먼지입자가 전기집진유닛(1)이 형성하는 전기장의 영역 내로 이동할 수 있도록 한다.The fan 3 moves air so that air passes through the ion generating unit 2 and the electrostatic dust collecting unit 1 so that the dust generated in the ion generating unit 2 and the dust particles in the air can come into contact with each other, So that the dust particles can be moved into the region of the electric field formed by the electrostatic dust collecting unit 1.
이러한 본 발명에 의한 소형 공기정화기는 공간 효율적으로 배치되어 전기집진의 효율이 우수한 전기집진유닛(1)을 구비하므로 소형으로 이루어짐에도 불구하고 공기를 효과적으로 정화해줄 수 있다.Since the small air purifier according to the present invention is provided with the electric dust collecting unit 1 which is disposed in a space-efficient manner and has a high efficiency of electrostatic dust collection, the air can be effectively purified even though it is small.
본 발명에 의한 소형 공기정화기에서 전기집진유닛(1)은 탈착 가능하게 형성되는 것이 바람직하다.In the small air purifier according to the present invention, the electric dust collecting unit 1 is preferably detachably formed.
상기했던 바와 같이 공기정화기를 계속해서 사용함에 따라 전기집진유닛(1)의 제1·2 극판(20, 40)에는 먼지가 쌓이므로 먼지를 제거해줄 필요가 있는데, 전기집진유닛(1)을 공기정화기에서 탈착할 수 있는 경우 먼지 제거와 같은 유지관리 작업을 용이하게 하는 것이 가능하다.As described above, as the air purifier is continuously used, dust is accumulated on the first and second electrode plates 20 and 40 of the electric dust collecting unit 1. Therefore, it is necessary to remove the dust. It is possible to facilitate maintenance work such as dust removal if it can be removed from the purifier.
전기집진유닛(1)의 제1, 2 극판(20, 40) 등은 프레임(100)에서 분리가 가능하므로 유지관리 작업의 용이성을 보다 향상시킬 수 있다.Since the first and second electrode plates 20 and 40 of the electric dust collecting unit 1 can be separated from the frame 100, the ease of maintenance work can be further improved.
상기 팬(3)은 전기집진유닛(1)에서 이온발생유닛(2) 방향으로 공기를 이동시키도록 회전하는 것이 바람직하다.The fan 3 is preferably rotated to move the air in the direction toward the ion generating unit 2 from the electric dust collecting unit 1. [
본 발명에 의한 소형 공기정화기에 의한 공기의 정화는 이온발생유닛(2)에 의한 이온 생성 과정, 이온에 의한 공기 중 먼지의 하전 과정 및 전기집진유닛(1)에 의한 먼지 집진 과정이 순서대로 진행되어 이루어지는데, 이온에 의한 공기 중 먼지의 하전 과정이 충분히 이루어지지 못하는 경우에는 전기집진유닛(1)이 작동하더라도 집진의 효율이 높지 못하다.The purification of air by the small air purifier according to the present invention is carried out in the order of the ion generation process by the ion generating unit 2, the charging process of the dust in the air by the ions, and the dust collecting process by the electric dust collecting unit 1 If the charging process of the dust in the air by the ions is not sufficiently performed, the efficiency of dust collection is not high even if the electric dust collecting unit 1 is operated.
또한, 공기의 유동을 기준으로 전기집진유닛(1)의 상류측에 이온발생유닛(2)을 배치하는 경우, 공기가 전기집진유닛(1)을 완전히 통과하기 전에 이온발생유닛(2)에서 발생된 이온에 의해 공기 중의 먼지가 최대한 하전되어야 한다.When the ion generating unit 2 is disposed on the upstream side of the electric dust collecting unit 1 based on the flow of air, the air is generated in the ion generating unit 2 before the air passes completely through the electric dust collecting unit 1 The dust in the air should be charged to the maximum by the ions that have been released.
이에 따라 먼지의 하전 유도되기 위한 공간상의 제한이 발생하고, 이를 극복하기 위해서 이온발생유닛(2)에 더 높은 수준의 고전압을 제공해야 하므로, 각 유닛의 부피를 증가시키거나 소비 에너지를 증가시키게 된다.Accordingly, space limitation for inducing charge of dust occurs, and in order to overcome this, it is necessary to provide a higher level of high voltage to the ion generating unit 2, so that the volume of each unit is increased or the consumed energy is increased .
따라서, 본 발명의 일 실시예는 공기가 전기집진유닛(1)에서 이온발생유닛(2) 방향으로 이동한 뒤 외부로 배출되도록 유동시킴으로써, 공기정화기 내부가 아닌 공기정화기 외부에서 먼지의 하전 과정이 진행될 수 있도록 한다. Accordingly, in an embodiment of the present invention, the air is flowed from the electrostatic dust collecting unit 1 toward the ion generating unit 2 and then discharged to the outside, whereby the process of charging dust outside the air purifier, So that it can proceed.
즉, 이온발생유닛(2)에서 발생한 이온을 곧바로 공기정화기 외부로 배출하여 이온이 공기 중의 먼지와 충분히 접촉하도록 한 후 팬(3)의 바람에 의해 공기정화기 내부로 유입되어 전기집진유닛(1)을 통과할 수 있도록 한다. That is, the ions generated in the ion generating unit 2 are immediately discharged to the outside of the air purifier so that the ions sufficiently come into contact with the dust in the air, and then flows into the air purifier by the wind of the fan 3, .
이에 따라, 공기정화기에 유입된 공기는 팬(3)에 의해 전기집진유닛(1)을 먼저 지나고 난 뒤에 이온발생유닛(2)을 지나게 된다. 팬(3)의 위치는 다양하게 결정될 수 있다.Accordingly, the air introduced into the air purifier passes through the ion generating unit 2 after passing through the electric dust collecting unit 1 by the fan 3 first. The position of the fan 3 can be variously determined.
공기정화기에 유입되는 공기의 먼지는 이미 이온발생유닛(2)에서 발생된 이온에 의해 하전되고, 공기정화기에 유입된 이후 전기집진유닛(1)을 통과하면서 공기 중으로부터 제거되며, 정화된 공기는 이온발생유닛(2)으로 이동하여 이온발생유닛(2)에서 발생한 이온과 함께 다시 외부로 배출된다.The dust of the air flowing into the air purifier is already charged by the ions generated in the ion generating unit 2, is introduced into the air purifier, is then removed from the air while passing through the electrostatic dust collecting unit 1, And then moves to the ion generating unit 2 and is discharged to the outside together with the ions generated in the ion generating unit 2. [
이온발생유닛(2)은 도 7에 도시되어 있는 바와 같이 소형 공기정화기의 내부에 위치할 수도 있으나, 이 경우 이온발생유닛(2)에 의해 발생된 이온이 공기정화기의 내벽에 달라붙거나, 공기정화기 내부에서 유동하는 과정에서 다양한 이유로 소멸되거나 양이 줄어들 수 있다.The ion generating unit 2 may be located inside the small air purifier as shown in FIG. 7, but in this case, ions generated by the ion generating unit 2 may stick to the inner wall of the air purifier, In the process of flowing inside the purifier, it may disappear or decrease in quantity for various reasons.
이에 따라, 본 발명의 일 실시예에서 방전 현상에 의해 이온을 발생시키는 부분인 방전극은 소형 공기정화기의 외부로 돌출 형성되는 것이 바람직하다.Accordingly, in one embodiment of the present invention, it is preferable that the discharge electrode, which is a portion for generating ions by the discharge phenomenon, is protruded to the outside of the small air purifier.
방전극은 한 쌍으로 구비될 수 있고, 적어도 일부가 공기정화기의 케이스 외부로 노출될 수 있다. 또한, 팬(3)에 의한 공기 유동을 고려하여 공기정화기의 공기배출구에 인접하게 배치될 수 있다.The discharge electrodes may be provided in pairs, and at least a part thereof may be exposed to the outside of the case of the air purifier. Also, it can be disposed adjacent to the air outlet of the air cleaner in consideration of the air flow by the fan 3.
이 경우, 이온발생유닛(2)에서 발생한 이온이 소형 공기정화기 내에서 소멸될 염려가 거의 없어 소형 공기정화기 외부의 먼지입자를 보다 효과적으로 하전시키는 것이 가능하다.한편, 본 발명의 일 실시예에서 방전극이 외부로 돌출된 길이는 필요에 따라 다양하게 결정될 수 있으며, 바람직하게는 0~10mm일 수 있고, 더욱 바람직하게는 3mm에서 6mm 사이일 수 있다. 이 경우, 공기정화기 외부에서 검출되는 이온의 양이 높게 나타날 수 있다. In this case, it is possible to more effectively charge the dust particles outside the small air purifier, since the ions generated in the ion generating unit 2 are not likely to disappear in the small air purifier. In the embodiment of the present invention, The outward protruding length can be variously determined as necessary, and can be preferably from 0 to 10 mm, and more preferably from 3 mm to 6 mm. In this case, the amount of ions detected outside the air cleaner may be high.
다만 본 발명의 실시예는 상기 범위에 한정되는 것이 아니며, 공기정화기의 구조, 공기의 유동이나 이온발생유닛의 작동조건 등에 따라 다양하게 결정될 수 있다.However, the embodiment of the present invention is not limited to the above-described range, and can be variously determined according to the structure of the air purifier, the flow of air, the operating conditions of the ion generating unit, and the like.
본 발명에 의한 공기정화기는 상기한 것과 같은 구성들 외에도 상기 이온발생유닛(2), 전기집진유닛(1) 및 팬(3)에 전원을 공급하는 전원부(미도시), 전원부에서의 전원 공급을 제어하기 위한 전원 버튼(미도시), 공기 중 먼지의 양을 측정하는 센서(미도시) 또는 센서의 측정값에 따라 이온 발생량이나 집진 세기를 조절하는 제어부(미도시) 등을 더 구비할 수 있다.이상을 통해 본 발명의 바람직한 실시예에 대하여 설명하였지만, 본 발명은 이에 한정되는 것이 아니고 특허청구범위와 발명의 상세한 설명 및 첨부한 도면의 범위 안에서 여러 가지로 변형하여 실시하는 것이 가능하고 이 또한 본 발명의 범위에 속하는 것은 당연하다.The air purifier according to the present invention has the above-described configurations, a power supply unit (not shown) for supplying power to the ion generating unit 2, the electric dust collecting unit 1 and the fan 3, A control unit (not shown) for controlling the amount of generated ions or the intensity of dust according to a measured value of a sensor (not shown) or a power button (not shown) for controlling the amount of dust in the air While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, and that various changes and modifications may be made without departing from the scope of the invention. And it goes without saying that they belong to the scope of the present invention.
