Description

습도센서를 구비한 전기집진장치의 고압발생회로High pressure generation circuit of electrostatic precipitator with humidity sensor

본 고안은 습도센서를 구비한 전기집진장치의 고압발생회로에 관한 것으로, 더욱 상세하게는 고압발생회로를 통해 발생되는 직류고전압이 여름철이나 우기의 높은 습도에 의해 집진장치가 다량의 오존발생 및 스파크현상을 일으켜 화재발생의 원인이 되는 것을 방지하기 위한 습도센서를 구비한 전기집진장치의 고압발생회로에 관한 것이다.The present invention relates to a high pressure generating circuit of an electric precipitator having a humidity sensor, and more particularly, the high DC generation voltage generated through the high pressure generating circuit is generated by the high humidity in summer or rainy season, and the dust collector generates a large amount of ozone and sparks. The present invention relates to a high-voltage generating circuit of an electrostatic precipitator having a humidity sensor for preventing a phenomenon from causing a fire.

일반적으로, 공기청정기나 에어컨에 설치되고 고압발생회로를 갖춘 전기집진장치는 다수개의 집진판이 평행하게 배열되고 집진판 사이는 고압선이 설치되어 집진판은 접지되고 고압선에는 플라스(+)의 고압이 공급된다.In general, an electrostatic precipitator installed in an air cleaner or air conditioner and having a high pressure generating circuit includes a plurality of dust collector plates arranged in parallel, a high voltage cable is installed between the dust collector plates, and the dust collector plate is grounded, and the high voltage cable is supplied with a high pressure of plastic (+).

이러한 집진장치는 팬의 구동에 따라 흡입되는 실내공기가 필터를 통과하면서 일차적으로 큰 물질이 제거되고 필터를 통과한 크기가 작은 이물질은 정전기를 갖도록 대전된 후 집진판을 통과하여 집진판에 집진되고 이물질이 제거된 공기는 실내로 배출되어 실내공기를 청정 한다.In the dust collector, as the indoor air sucked by the driving of the fan passes through the filter, large substances are first removed, and small foreign substances passing through the filter are charged to have static electricity, and then are collected through the dust collecting plate and collected in the dust collecting plate. The removed air is discharged into the room to clean the indoor air.

그러나, 여름철이나 우기의 높은 습도에 따라 공기저항밀도가 높아 집진판에서 스파크현상이 일어나 화재의 위험성과 다량의 오존을 생성하여 공기중의 산소가 파괴되는 문제점이 있었다.However, there is a problem that spark phenomenon occurs in the dust collecting plate due to high air resistance density according to the high humidity of the summer or rainy season, the risk of fire and the generation of a large amount of ozone to destroy oxygen in the air.

본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 그 목적은, 고압발생회로로부터 발생되는 직류고전압을 습도의 변화에 따라 변화시킴으로써 높은습도에서도 스파크현상이 일어나지 않는 전기집진장치를 제공하는 것이다.The present invention has been made to solve the above problems, the object of the present invention is to provide an electrostatic precipitator which does not occur in high humidity by changing the DC high voltage generated from the high-voltage generating circuit according to the change of humidity. .

본 고안의 상기와 같은 목적은, 습도를 감지하여 전기집진장치의 직류고전압을 조절하여 스파크발생을 방지함으로써 달성되며, 본 고안은 습도를 감지하는 감지부와, 감지부의 출력전압으로 고압발생부를 제어하는 제어부를 포함한 습도센서를 구비한 전기집진장치의 고압발생회로를 제공한다.The above object of the present invention is achieved by controlling the high voltage DC voltage of the electrostatic precipitator by sensing humidity to prevent sparking, and the present invention controls the high pressure generator with a sensing unit for sensing humidity and an output voltage of the sensing unit. It provides a high-pressure generating circuit of the electrostatic precipitator having a humidity sensor including a control unit.

이하, 본 고안의 실시예를 첨부된 도면에 의하여 설명하면, 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도1은 본 고안의 실시예의 회로도로서, 습도를 감지하는 감지부(10)와, 감지부(10)로부터 출력된 전압에 의해 고압발생부(30)를 제어하는 제어부(20)를 포함하여 구성되어 있다.1 is a circuit diagram of an embodiment of the present invention, comprising a sensing unit 10 for sensing humidity and a control unit 20 for controlling the high pressure generating unit 30 by a voltage output from the sensing unit 10. It is.

상기 감지부(10)는 습도에 따라 저항이 변화하는 습도센서(S)와 OP앰프(OP)로 구성된다.The sensing unit 10 is composed of a humidity sensor (S) and the OP amplifier (OP) that the resistance changes according to the humidity.

상기 제어부(20)는 OP앰프(OP)로부터 출력된 전압에 의해 작동되는 트랜지스터(TR1)를 가지고 있다.The control unit 20 has a transistor TR1 operated by a voltage output from the OP amplifier OP.

상기 고압발생부는 일반적인 전기집진장치의 고압발생회로를 보인 것이다.The high pressure generating unit shows a high pressure generating circuit of a general electric dust collector.

이하, 본 고안의 구성에 따른 작동원리를 살펴본다.Hereinafter, look at the operating principle according to the configuration of the present invention.

먼저, 습도가 높아지면 습도센서(S)의 저항이 낮아져 OP앰프(OP)의 (+)단과 (-)단으로 입력되는 두 전압의 차와 비례하는 전압이 출력되고, 이 출력전압은 트랜지스터(TR1)의 베이스단에 입력되어, 이 전압을 트랜지스터(TR1)의 베이스와 에미터단 사이의 전압에서 뺀 전압이 에미터를 통해 출력되어 고압발생부(30)로 공급된다.First, when the humidity increases, the resistance of the humidity sensor S decreases, and a voltage proportional to a difference between two voltages input to the (+) and (-) terminals of the OP amplifier OP is output, and the output voltage is a transistor ( The voltage inputted to the base end of TR1 and subtracted this voltage from the voltage between the base of the transistor TR1 and the emitter end is output through the emitter and supplied to the high voltage generator 30.

한편, 고압발생부(30)로 출력되는 전압은 베이스단으로 입력되는 전압의 크기에 따라 변화되며, 이때 베이스단과 에미터단 사이의 전압은 고정되어 있다.On the other hand, the voltage output to the high-voltage generator 30 is changed according to the magnitude of the voltage input to the base end, wherein the voltage between the base end and the emitter end is fixed.

즉, 고압발생부(30)로 공급되는 전압변화는, 감지부(10)의 습도센서(S)를 통해 변화되는 저항값에 의한 OP앰프(OP)의 출력전압의 변화에 따른 것이다.That is, the voltage change supplied to the high pressure generator 30 is due to the change in the output voltage of the OP amplifier OP due to the resistance value changed through the humidity sensor S of the sensing unit 10.

이렇게 고압발생회로의 직류고전압은, 습도센서(S)에서 감지되는 습도에 따라 변화되는 저항값에 의해 변화되는데, 즉, 습도가 높으면 OP앰프(OP)를 거쳐 출력되는 전압이 낮아져 고압발생부(30)에서 발생되는 전압이 낮아지고, 습도가 낮아지면 OP앰프(OP)를 거쳐 출력되는 전압이 높아져 고압발생부(30)의 전압이 높아지게 된다.The DC high voltage of the high voltage generating circuit is changed by a resistance value which is changed according to the humidity detected by the humidity sensor S. That is, when the humidity is high, the voltage output through the OP amplifier OP is lowered to increase the voltage. When the voltage generated by 30) is lowered and the humidity is lowered, the voltage outputted through the OP amplifier OP is increased to increase the voltage of the high voltage generator 30.

그리하여, 상기 고압발생회로가 내장된 전기집진장치의 집진판과 대전극을 통해 일어나는 코로나방전이 습도에 따라 제어되므로 집진 또는 이온화 현상이 안정적으로 발생된다.Thus, the corona discharge generated through the dust collecting plate and the counter electrode of the electrostatic precipitator in which the high-pressure generator circuit is embedded is controlled according to humidity, so that dust collection or ionization phenomenon is generated stably.

한편, 상기 본 고안의 실시에서는 공기청정기나 에어컨 및 온풍기의 전기집진장치에 감지부의 습도센서를 내장한 구조이나, 습도센서만을 별도로 공기청정기나 에어컨 및 온풍기의 본체 외부에 설치하여도 무방하다.On the other hand, in the implementation of the present invention, the structure of the humidity sensor in the air purifier or air conditioner and the electric precipitator of the warm air heater, or the humidity sensor may be installed separately outside the main body of the air cleaner or air conditioner and hot air heater.

이와 같이 본 고안의 실시예에 의한 습도센서를 구비한 전기집진장치의 고압발생회로는, 습도가 높은 우기에 발생되는 스파크현상을 방지하여 화재발생을 방지하는 효과가 있다.As described above, the high-pressure generation circuit of the electrostatic precipitator having the humidity sensor according to the embodiment of the present invention has an effect of preventing the occurrence of fire by preventing the spark phenomenon generated in the rainy season with high humidity.

또한, 습도에 따라 직류고전압이 자동 조절되는 전기집진장치를 통해 음이온을 발생시키는 공기청정기나 에어컨 및 온풍기의 집진장치 등의 성능을 소비자가 한층 더 신뢰할 수 있게 하는 장점이 있다.In addition, there is an advantage that the consumer can be more reliable in the performance of the dust collector of the air cleaner or air conditioner and hot air generator that generates negative ions through the electrostatic precipitator that automatically adjusts the DC high voltage according to the humidity.
