본 발명은 전기집진기가 부착된 공기조화기에 관한 것으로, 특히 이온화된 먼지와 동일한 극성의 전압을 열교환기에 인가함으로써 이온화 먼지에 반발력을 유도하여 열교환기에 먼지가 흡착되는 것을 방지할 수 있도록 된 열교환기의 먼지흡착방지장치에 관한 것이다.The present invention relates to an air conditioner equipped with an electrostatic precipitator, in particular, by applying a voltage having the same polarity as the ionized dust to the heat exchanger to induce a repulsive force to the ionized dust to prevent the adsorption of dust in the heat exchanger It relates to a dust adsorption prevention device.

전기집진기가 부착된 공기조화기의 일반적인 구조는 다음과 같다.The general structure of an air conditioner equipped with an electrostatic precipitator is as follows.

즉, 실내의 공기를 정화하기 위한 전기집진기가 실내열교환기의 전면에 부착되고, 상기 열교환기의 후면에는 외부로부터 열교환이 이루어지게될 공기를 흡입하는 실내송풍기가 설치되어있다.That is, an electrostatic precipitator for purifying indoor air is attached to the front of the indoor heat exchanger, and an indoor blower is installed at the rear of the heat exchanger to suck air to be heat-exchanged from the outside.

한편 상기 실내열교환기는 연결배관을 통해 실외열교환기에 연결되고 이 실외열교환기의 후면에는 열교환이 이루어진 공기를 외부로 배기시키는 실외송풍기가 설치되어 있다.On the other hand, the indoor heat exchanger is connected to the outdoor heat exchanger through a connecting pipe, and an outdoor blower is installed at the rear of the outdoor heat exchanger to exhaust the heat-exchanged air to the outside.

실내의 공기를 정화하는 전기집진기의 구조와 동작을 보다 구체적으로 설명하면 다음과 같다.The structure and operation of the electrostatic precipitator for purifying indoor air will be described in more detail as follows.

즉, 전기집진기는 복수개의 이온화선과 전기집진판, 가속전극판 및 고전압발생기로 구성되고, 이 고전압발생기는 (+)고전압연결선을 매개로 이온화선과 가속전극판에 접속됨과 동시에 (-)연결선을 통해 전기집진판에 접속되어 있다.That is, the electrostatic precipitator is composed of a plurality of ionization lines, electrostatic precipitating plates, acceleration electrode plates, and high voltage generators. The high voltage generators are connected to the ionization lines and the acceleration electrode plates via positive high voltage connecting wires, It is connected to the dust collecting plate.

따라서 전기집진기로 유입되는 공기중에 포함되어 있는 분진입자가 이온화선에 의해 하전되게 되면 이 하전된 먼지는 실내송풍기에 의해서 공기조화기 내부로 빨려들게 되고 이때 전기집진판에 포함하게 하는 것이다.Therefore, when the dust particles contained in the air flowing into the electrostatic precipitator are charged by the ionization line, the charged dust is sucked into the air conditioner by the indoor blower and is included in the electrostatic precipitator.

그러나 종래에는 전기집진판에 의해서 포획되지 않는 대전된 먼지는 전기집진기를 그대로 통과하게 되고 그후 열교환기에 반대극성을 대전시켜 이곳에 달라붙게 되는 것이다.However, conventionally, the charged dust that is not captured by the electrostatic precipitator is passed through the electrostatic precipitator as it is, and then is charged with the opposite polarity to the heat exchanger to be attached thereto.

즉, 전기집진기에 의해서 대전된 먼지는 열교환기를 지나는 동안 열교환기 자체를 그 반대의 극성으로 대전시키게 되어 상기 열교환기는 반대극성 끼리의 인력으로 대전된 먼지를 보다 강력하게 흡착시키게 되는 것이다. 따라서 상기 전기집진기는 실내의 공기를 정화시키는 작용을 하게 되나 종래에는 이곳에서 포획되지 못한 하전된 먼지를 열교환기에 대량 흡착시키게 됨으로써 오히려 열교환기의 효율을 저하시키고 기기의 수명을 단축시키게 된다고 하는 문제점이 발생되었다.That is, the dust charged by the electrostatic precipitator charges the heat exchanger itself with the opposite polarity while passing through the heat exchanger, and thus the heat exchanger more strongly absorbs the charged dust by the attraction force between the opposite polarities. Therefore, the electrostatic precipitator acts to purify the air in the room, but conventionally, since the charged dust that has not been trapped therein is adsorbed to the heat exchanger in a large amount, the efficiency of the heat exchanger is reduced and the life of the device is shortened. Occurred.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위하여 발명된 것으로, 전기집진기로 하여금 흡입된 공기의 분진을 제거하고 미처 제거하지 못한 분진은 열교환기를 그대로 통과시켜 이를 외부로 배출함으로써 외부에서 순환되어 재차 공기조화기내로 유입될때 상기 전기집진기에서 포획할 수 있도록 된 열교환기의 먼지흡착방지장치를 제공하는데 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above. The dust collected by the electrostatic precipitator is not removed, and the dust that is not removed is circulated from the outside by passing through the heat exchanger as it is and discharged to the outside. It is an object of the present invention to provide a dust adsorption preventing device of a heat exchanger that is capable of being captured by the electrostatic precipitator when introduced into an air conditioner.

상기와 같은 목적을 달성하기 위한 본 발명에 의한 열교환기의 먼지흡착방지장치는 고전압발생기의 (+)연결선이 이온화선 및 가속전극판에 접속되고 고전압발생기의 (-)연결선이 상기 가속전극판 사이에 배설된 전기집진판에 접속된 전기집진기와, 상기 전기집진기를 지난 공기와 열교환하도록 상기 전기집진기의 후측에 배설된 열교환기를 구비한 공기조화기에 있어서,The dust adsorption prevention device of the heat exchanger according to the present invention for achieving the above object is a (+) connection line of the high voltage generator is connected to the ionization line and the acceleration electrode plate and the (-) connection line of the high voltage generator between the acceleration electrode plate An air conditioner having an electrostatic precipitator connected to an electrostatic precipitator disposed in the air purifier, and a heat exchanger disposed at a rear side of the electrostatic precipitator so as to exchange heat with the air passing through the electrostatic precipitator,

상기 고전압발생기의 (+)연결선은 상기 열교환기에 접속된 구조로 되어 있는 것을 특징으로 한다.The positive connection line of the high voltage generator is characterized in that the structure is connected to the heat exchanger.

이러한 구조로 된 본 발명은 전기집진기에서 미처 포획되지 않은 이온화된 먼지를 열교환기를 거치는 동안 이곳을 그대로 통과시켜 일단 외부로 배출한 다음 외부에서 다른 먼지와 전기적으로 결합되도록 유도하여 먼지 입자를 크게한 후 다시 기기내부로 흡입될때 상기 전기집진기에서 포획할 수 있도록 된 것이다.According to the present invention having such a structure, the ionized dust not captured in the electrostatic precipitator is passed through the heat exchanger as it is and is discharged to the outside once, and then induced to be electrically coupled with other dust from the outside to increase the dust particles. It can be captured by the electrostatic precipitator when it is sucked back into the apparatus.

이하 본 발명의 일실시예를 도면을 참조로 하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

제1도는 본 발명에 따른 공기조화기의 구성을 개략적으로 도시한 것으로, 실내의 공기를 정화시키는 전기집진기(1)가 실내열교환기(2)의 전면에 부착되고 이 열교환기(2)의 후면에는 열교환이 이루어지게 될 외부공기를 흡입하는 실내송풍기(3)가 설치된 구조로 되어 있다.1 schematically shows the configuration of an air conditioner according to the present invention, in which an electrostatic precipitator 1 for purifying indoor air is attached to the front of the indoor heat exchanger 2 and the rear of the heat exchanger 2. It has a structure in which the indoor blower (3) is installed to suck the outside air to be heat exchange.

또한 상기 실내열교환기(2)는 연결배관(4)을 통해 실외열교환기(5)에 접속되고 이 실외열교환기(5)의 후면에는 공기를 강제 배기시키는 송풍기(6)가 설치되어 있다.In addition, the indoor heat exchanger (2) is connected to the outdoor heat exchanger (5) via a connecting pipe (4), and the rear side of the outdoor heat exchanger (5) is provided with a blower (6) for forcibly evacuating air.

상기 전기집진기(1)의 구조를 보다 구체적으로 설명하면 다음과 같다.Referring to the structure of the electrostatic precipitator 1 in more detail as follows.

즉, 전기집진기(1)는 제1도에 도시한 바와 같이 복수개의 이온화선(7)과 전기집진판(8), 가속전극판(9) 및 고전압발생기(10)로 구성되고, 이 고전압발생기(10)는 (+)고전압연결선(11)을 매개로 이온화선(7)과 가속전극판(9)에 각각 접속되면서 동시에 (-)연결선(12)을 통해 전기집진판(8)에 접속되는데, 특히 상기 고전압발생기(10)는 (+)고전압연결선(11)을 통해 열교환기(12)에 접속되어 이 열교환기(2)의 도시되지 않은 플레이트판에 (+)전계를 형성하게 된다.That is, the electrostatic precipitator 1 is composed of a plurality of ionization lines 7, an electrostatic precipitating plate 8, an acceleration electrode plate 9, and a high voltage generator 10 as shown in FIG. 1. 10 is respectively connected to the ionization line 7 and the acceleration electrode plate 9 via the positive high voltage connection line 11 and simultaneously to the electrostatic precipitating plate 8 through the negative connection line 12. The high voltage generator 10 is connected to the heat exchanger 12 via a positive high voltage connection line 11 to form a positive electric field on an unshown plate plate of the heat exchanger 2.

다음은 상기 구조로 된 본 발명의 작용 및 효과에 대하여 설명한다.The following describes the operation and effects of the present invention having the above structure.

전기집진기(1)를 구성하는 전기집진판(8)과 이온화선(7) 그리고 가속전극판(9)에 고전압발생기(10)로부터 고전압 직류전원을 인가하게 되면 복수개의 이온화선(7)에 이온화 전류가 흐르게 되고, 이러한 이온화 전류는 일정 간격으로 설치되어 있는 전기집진판(8)과 가속전극판(9) 그리고 전기집진판(10)과 이온화선(7) 들간에 균일 전계를 형성하게 된다.When high voltage DC power is applied from the high voltage generator 10 to the electrostatic precipitator 8, the ionization line 7 and the acceleration electrode plate 9 constituting the electrostatic precipitator 1, the ionization current is applied to the plurality of ionization lines 7. This ionization current forms a uniform electric field between the electrostatic precipitator plate 8, the acceleration electrode plate 9, and the electrostatic precipitator plate 10 and the ionization lines 7 provided at regular intervals.

이에 따라 전기집진기로 유입되는 공기중에 포함되어 있는 분진입자(14)는 이온화선(7)에 의해 하전되게 되고 이러한 하전된 분진입자(14)는 전기집진판(8)과 가속전극판(9)간에 형성된 가속 전계에 의해 반대극성이 인가되는 전기집진판(8)쪽으로 가속되고 그후 이 전기집진판(8)의 후단부에 균일한 두께로 집진되게 된다.Accordingly, the dust particles 14 contained in the air flowing into the electrostatic precipitator are charged by the ionization line 7, and the charged dust particles 14 are interposed between the electrostatic precipitator 8 and the acceleration electrode plate 9. The accelerated electric field is accelerated toward the electrostatic precipitating plate 8 to which the opposite polarity is applied, and is then collected in a uniform thickness at the rear end of the electrostatic precipitating plate 8.

이와 같이 상기 전기집진기(1)에서 하전된 분진입자(14)는 전기집진판(8)에 의해 포획되게 되나 그 일부는 하전된체로 열교환기(2)로 이동하게 된다.As such, the charged dust particles 14 in the electrostatic precipitator 1 are captured by the electrostatic precipitator 8, but a part thereof is moved to the heat exchanger 2 in a charged body.

한편 열교환기(2)는 상기 고전압발생기(10)로부터 (+)연결선(11)을 통해 (+)전하를 공급받아 도시되지 않은 플레이트상에 (+)전하군을 형성하게 되고, 이 (+)전하군은 상기 플레이트 주위에 (+)전계를 형성하면서 그 자체내로 유입되는 (+)극성으로 하전된 분리입자(14)에 반발력을 가하게 된다.Meanwhile, the heat exchanger 2 receives positive charges from the high voltage generator 10 through the positive connection line 11 to form a positive charge group on a plate (not shown). The charge group exerts a repulsive force on the positively charged separation particles 14 that flow into it while forming a positive electric field around the plate.

따라서 하전된 분진입자(14)는 열교환기(2)로부터 반발되면서 이격된체 이곳을 그대로 통과하여 일단 외부로 배출된 다음 다시 재차 실내열교환기(2)로 흡입될때 상기 전기집진기에서 포획되게 되는 것이다.Therefore, the charged dust particles 14 are captured by the electrostatic precipitator when they are repulsed from the heat exchanger 2 and passed through the spaced body as it is, are discharged to the outside and then sucked back into the indoor heat exchanger 2 again. .

이와 같이 본 발명은 열교환기의 플레이트에 이온화선과 같은 극성의 고전압을 인가함으로써 플레이트 주위에 전계를 형성하게 하고 이 전계는 유입되는 하전된 먼지에 반발력을 가하여 먼지가 플레이트 표면에 흡착되게 되는 것을 방지하게 됨은 물론 이에 따라 열교환기의 열교환효율을 증대시킬 수 있으며 또한 흡착되지 않은 먼지는 실내에 부유하고 있다가 전기집진기로 재유입되게 함으로써 이때 전기집진기에서 포획되게 할수 있는 효과가 있는 것이다.As described above, the present invention applies a high voltage of the same polarity as the ionization line to the plate of the heat exchanger to form an electric field around the plate, and the electric field exerts a repulsive force on the incoming charged dust to prevent the dust from adsorbing on the surface of the plate. Of course, the heat exchanger efficiency of the heat exchanger can be increased accordingly, and the dust that is not adsorbed is suspended in the room and is re-introduced into the electrostatic precipitator.
