Fig. 2 is a perspective view of an ion generator of a harmonizer; Fig.

본 발명의 일 실시예에 따른 공기조화기는 필터하우징(140)에 구비되어 이온을 발생하는 이온발생장치(160)를 포함한다.The air conditioner according to an embodiment of the present invention includes an ion generating device 160 provided in a filter housing 140 to generate ions.

이온발생장치(160)는 필터하우징(140)의 플로우가이드(146)에 배치된다. 이온발생장치(160)는 고전압이 인가되어 방전하여 공기 중의 분자를 이온화하여 이온을 발생한다.The ion generating device 160 is disposed in the flow guide 146 of the filter housing 140. The ion generating device 160 generates ions by applying high voltage to discharge molecules to ionize molecules in the air.

이온발생장치(160)는 필터하우징(140)의 필터장착부(148)에 장착되는 필터어셈블리(10)의 상측에 배치된다. 이온발생장치(160)는 공기의 유동 방향을 기준으로 필터어셈블리(10)보다 하류측에 배치된다. 본 실시예에서 공기는 하측에서 상측으로 유동하므로 이온발생장치(160)는 필터어셈블리(10)보다 상측에 배치되어 이온발생장치(160)에서 발생된 이온이 필터어셈블리(10)의 전기집진모듈(15)에 포집되지 않도록 한다.The ion generating device 160 is disposed above the filter assembly 10 mounted on the filter mount 148 of the filter housing 140. The ion generating device 160 is disposed on the downstream side of the filter assembly 10 with respect to the flow direction of the air. Since the air flows from the lower side to the upper side in the present embodiment, the ion generating device 160 is arranged above the filter assembly 10 so that the ions generated in the ion generating device 160 are supplied to the electrostatic dust collecting module 15).

이온발생장치(160)는 필터하우징(140)의 유입구(142)의 상측에 배치된다. 이온발생장치(160)는 고전압이 발생되어 위험할 수 있으므로 필터어셈블리(10)의 분리시 유입구(142)의 그릴에 의하여 보호될 수 있다.The ion generating device 160 is disposed above the inlet 142 of the filter housing 140. The ion generating device 160 may be protected by the grill of the inlet 142 upon detachment of the filter assembly 10 because a high voltage is generated and may be dangerous.

The ion generating device 160 is disposed on the upstream side of the humidifying medium 50 with respect to the flow direction of the air. Since the air flows from the lower side to the upper side in the present embodiment, the ion generating device 160 is disposed below the humidifying medium 50 so that the ions generated by the ion generating device 160 are blown by the blowing fan 24 into the humidifying medium 50). The ions generated in the ion generating device 160 sterilize the moisture contained in the humidifying medium 50 and the humidifying medium 50 itself.

The electrode 161 receives a high voltage generated in the high voltage generating circuit and discharges the voltage. The electrode 161 ionizes molecules in the air to generate anions such as OH- and O-, and cations such as H +.

전극(161)은 카본 파이버로 형성된다. 극세의 카본 파이버를 전극(161)으로 하여 코로나 방전에 의하여 이온을 발생한다. 전극(161)은 마이크로미터 단위의 직경을 갖는 극세의 카본 파이버가 수백개가 전극(161)에 묶인 브러시 형태인 것이 바람직하다. 본 실시예에서 전극(161)은 직경 7 ㎛의 카본 파이버가 1000개 정도 모인 브러시 형태이다.The electrode 161 is formed of a carbon fiber.
