본 발명은 공기청정기의 고압발생기 제어회로에 관한 것으로 특히 실내의 오염된 공기를 흡입하기 위하여 구동시키는 팬모터가 구동시에만 고압발생기를 구동시킬 수 있도록 한 공기청정기의 고압발생기 제어회로에 관한 것이다.The present invention relates to a high-pressure generator control circuit of an air cleaner, and more particularly, to a high-pressure generator control circuit of the air cleaner to drive the high-pressure generator only when the fan motor is driven to suck the polluted air in the room.

일반적으로 공기청정기의 고압발생기는 팬모터 구동시 같이 구동되면서 상기 팬모터에 의하여 흡입된 오염공기를 대전시켜 대전된 오염공기가 반대극성의 공기청정 필터에 응착되도록 되어 있는바, 종래의 고압발생기는 팬모터 구동시 기계적인 구동수단에 의하여 같이 구동토록 되어 있어서, 간혹 기계적인 구동수단에 이상으로 팬모터의 구동이 정지하였음에도 불구하고 고압발생기가 구동하면서 고압발생시키는가 하면, 반면에 팬모터는 구동하나 고압발생기가 구동하지 않는 경우가 있어, 상기 이상동작으로 인한 실내 오염공기를 안정적으로 청정시켜 주지 못하는 문제점을 가지게 되었다.In general, the high pressure generator of the air cleaner is driven when the fan motor is driven, thereby charging the polluted air sucked by the fan motor so that the charged polluted air is allowed to adhere to the air cleaning filter of the opposite polarity. When the fan motor is driven, it is driven by the mechanical driving means. Sometimes, even though the driving of the fan motor is stopped by the mechanical driving means, the high pressure generator generates high pressure while driving the fan motor. Since the high-pressure generator may not be driven, there is a problem that can not stably clean the indoor polluted air due to the abnormal operation.

따라서 본 발명의 목적은 팬모터 구동시 그 구동전압을 이용하여 고압발생기를 같이 구동시키되, 팬모터 정지시 같이 정지시켜 실내 오염공기를 효과적으로 청정시킬 수 있는 고압발생기 구동회로를 제공하는데 있으며, 상기의 목적을 실현시키기 위하여 본 발명은 팬모터 구동시 구동하면서 고압을 발생토록된 고압발생기를 구비하여서 된 공기청정기에 있어서 팬모터에 이 팬모터 구동에 따라 구동전압을 출력시키는 팬모터 구동감지부와, 이 구동전압 출력부에서 출력되는 전압을 소정레벨로 평활시키는 평활회로와, 고압발생기를 구동제어하는 고압발생기 구동제어부를 구성시켜서 된 것을 특징으로 한다.Accordingly, an object of the present invention is to provide a high-pressure generator driving circuit that can drive the high-pressure generator together using the drive voltage when the fan motor is driven, to stop the fan motor together to effectively clean indoor polluted air. In order to realize the object of the present invention, a fan motor drive detection unit for outputting a driving voltage to the fan motor in accordance with the fan motor in the air cleaner provided with a high-pressure generator to generate a high pressure while driving the fan motor, A smoothing circuit for smoothing the voltage output from the driving voltage output section to a predetermined level, and a high voltage generator driving control section for driving control of the high voltage generator are characterized by the above-mentioned.

이하 첨부된 도면에 의거 본 발명을 상세히 설명하면 다음과 같다. 제 1 도에 도시한 바와 같이 팬모터(FM)구동시 구동하면서 고압을 발생토록된 고압발생기(HV-Gen)를 구비하여서 된 공기청정기에 있어서,상기 팬모터(FM)의 양단간에 구동신호를 인가하는 포토커플러(PC), 다이오드(P-D), 저항(R8)(R9), 분압저항(R2)(R3)로 구성된 팬모터 구동감지부(가)와, 이 구동전압출력부(가)에서 출력된 전압을 소정의 레벨로 평활시키는 저항(R4), 콘덴서(C1)로 구성된 평활회로(나)와, 상기 평활회로(나)로부터 상기 고압발생기(HV-Gen)를 구동제어하는 트랜지스터(TR1)(TR2), 바이어스저항(R5)(R6)(R7)으로 구성되고 본 신호로써 고압발생기(HV-Gen)를 제어하는 고압발생기 구동제어부(다)로 구성하여서 된 것이다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, an air cleaner including a high voltage generator (HV-Gen) that generates high pressure while driving a fan motor (FM), wherein drive signals are provided between both ends of the fan motor (FM). The fan motor drive detecting unit (A), which is composed of an applied photo coupler (PC), a diode (PD), resistors R8 (R9), and a voltage divider resistor (R2) (R3), A smoothing circuit (b) consisting of a resistor (R4) and a capacitor (C1) for smoothing the output voltage to a predetermined level, and a transistor (TR1) for driving control of the high voltage generator (HV-Gen) from the smoothing circuit (b). ) Is composed of a high voltage generator drive control unit (C) which is composed of TR2, bias resistors R5, R6, and R7 and controls the high voltage generator HV-Gen with this signal.

도면중 미설명부호 D2는 역전류방지용 다이오드이다.In the figure, reference numeral D2 denotes a reverse current prevention diode.

상기와 같이 구성하여서 된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

먼저 회로에 전원을 인가시킨 상태에서, 전원스위치(도시되지 않음)를 온시키면 전원전압(AC)로부터 팬모터(FM)에 교류전압이 흐르게 되므로 팬모터(FM)는 구동하면서 오염된 공기를 흡입하는 동시에 이 팬모터(FM)의 양단간에 접속된 포토커플러(PC)의 다이오드(P-D)에 전류가 흘러 발광을 하게되고, 팬모터 구동감지부(가)의 포토커플러(PC)의 포토트랜지스터(P-TR)에서는 상기 포토다이오드(P-D)로부터의 빛을 수광하게 되어 이 포토트랜지스터(P-TR)를 도통시키게 된다.When the power switch (not shown) is turned on while power is supplied to the circuit, an AC voltage flows from the power voltage AC to the fan motor FM, so that the fan motor FM sucks contaminated air while driving. At the same time, current flows through the diode PD of the photocoupler PC connected between the both ends of the fan motor FM to emit light, and the phototransistor of the photocoupler PC of the fan motor driving detection unit The P-TR receives light from the photodiode PD to conduct the phototransistor P-TR.

따라서 전원전압(B+)는 포토트랜지스터(P-TR)으로 흐르게 되고 상기 전원전압(B+)는 분압저항(R2)(R3)에 의하여 분압되면서 평활회로(나)의 저항(R4) 콘덴서(C1)를 통해 소정의 레벨로 평활되게 되며 이 평활된 전압은 고압발생기 구동제어부(다)의 저항(R5)를 통해서 트랜지스터(TR1)의 베이스단자에 인가되게 되므로 트랜지스터(TR1)는 온되게 되어 전원전압(B+)은 바이어스저항(R6), 콜렉터단자 및 에미터단자를 통해 흐르게 된다.Therefore, the power supply voltage (B + ) flows to the phototransistor (P-TR) and the power supply voltage (B + ) is divided by the divided resistor (R2) (R3) while the capacitor (R4) of the smoothing circuit (B) ( The smoothed voltage is smoothed to a predetermined level through C1), and the smoothed voltage is applied to the base terminal of the transistor TR1 through the resistor R5 of the high voltage generator driving control unit (C). The voltage B + flows through the bias resistor R6, the collector terminal, and the emitter terminal.

따라서 상기 트랜지스터(TR1)의 콜렉터단자에는 저전위상태가 되며 이 저전위는 트랜지스터(TR2)의 베이스단자에 인가되어 PNP형인 트랜지스터(TR2)를 온 시켜주게 되므로 전원전압(B+)이 에미터단자 및 콜렉터단자를 통해서 고압을 발생시키는 고압발생기(HV-Gen)를 구동시키게 된다.Accordingly, the collector terminal of the transistor TR1 is in a low potential state, and the low potential is applied to the base terminal of the transistor TR2 to turn on the transistor NP of PNP type, so that the power supply voltage B + is an emitter terminal. And a high voltage generator (HV-Gen) generating high pressure through the collector terminal.

그러므로 상기 고압발생기(HV-Gen)는 고압을 발생시켜 상기 팬모터(FM)가 구동하면 흡입된 오염공기를 대전시켜 대전된 오염된 공기를 청정시켜 주게 되는 것이다.Therefore, the high pressure generator (HV-Gen) generates a high pressure to charge the polluted air sucked when the fan motor (FM) is driven to clean the charged polluted air.

이어서 상기 팬모터(FM)의 구동을 정지시키게 되면 팬모터(FM) 양단간에는 전류가 흐르지 못하므로 구동전압출력부(가)의 포토트랜지스터(P-TR)는 오프되게 되고, 따라서 포토트랜지스터(P-TR)에는 전류가 흐르지 않게되어 고압발생기 구동제어부(다)의 트랜지스터(TR1)를 온시키지 못하게 된다.Subsequently, when the driving of the fan motor FM is stopped, no current flows between both ends of the fan motor FM, so that the phototransistor P-TR of the driving voltage output unit A is turned off, and thus the phototransistor P No current flows through -TR so that the transistor TR1 of the high voltage generator drive control unit (C) cannot be turned on.

따라서 트랜지스터(TR1)의 콜렉터단자의 전위는 고전위가 되며 이 고전위는 트랜지스터(TR2)의 베이스단자에 인가되지만 상기 트랜지스터(TR2)는 PNP형이므로 오프되게되어 전원전압(B+)가 고압발생기(HV-Gen)에 인가되지 못하므로 상기 고압발생기(HV-Gen)는 고압을 발생시키지 못하게 되는 것이다.Therefore, the potential of the collector terminal of the transistor TR1 becomes high and this high potential is applied to the base terminal of the transistor TR2. However, since the transistor TR2 is of the PNP type, it is turned off so that the power supply voltage B + is a high voltage generator. Since it is not applied to (HV-Gen), the high pressure generator (HV-Gen) will not generate a high pressure.

이상에서 설명한 바와 같이 본 발명은 팬모터 구동시에만 고압발생기가 구동하면서 고압을 발생시키고 팬모터가 구동하지 않으면 고압발생기도 구동하지 않게 함으로써 팬모터가 구동하였는데도 고압발생기가 구동하지 않거나 또는 팬모터가 정지하였는데도 고압발생기가 구동하면서 고압을 발생시키게 되는 이상동작으로 인한 실내 오염공기를 효과적으로 청정시켜주지 못하는 문제점을 해소할 수 있는 이점을 제공하게 되는 것이다.As described above, the present invention generates a high pressure while the high pressure generator is driven only when the fan motor is driven, and if the fan motor is not driven, the high pressure generator is not driven so that the high pressure generator is not driven or the fan motor is not driven. Even if it is stopped, it is to provide an advantage that can solve the problem that can not effectively clean the indoor polluted air due to the abnormal operation that generates a high pressure while the high-pressure generator is running.
