본 고안은 실내공기를 청정하게 하는 공기청정기에 있어서, 필터에 걸러진 먼지량을 검출하여 필터의 교환을 지시하는 공기청정기의 필터교환 지시회로에 관한 것이다.The present invention relates to a filter replacement instruction circuit of an air cleaner that detects an amount of dust filtered by a filter and instructs replacement of the filter in an air cleaner for cleaning indoor air.

종래의 공기청정기들은 필터에 많은 양의 먼지가 걸러졌을 경우에 이를 표시하지 않고 단지 동작전원만 인가되면 구동되게 하였으므로 필터에 많은 양의 먼지가 걸려져 제 기능을 발휘하지 못할 경우에 사용자는 이를 알지 못하고 공기청정기를 구동시켰을 뿐만 아니라 많은 소음이 발생하고, 실내 공기를 순환시키는 팬모타가 과열되어 손상됨은 물론 실내공기도 청정하게 유지시키지 못하는 등의 문제점이 있었다.Conventional air cleaners do not indicate when a large amount of dust is filtered out, but only when operating power is applied. Therefore, the user does not know when a large amount of dust is caught in the filter and does not function properly. Not only did the air cleaner not only drive a lot of noise, there is a problem that the fan motor for circulating the indoor air is overheated and damaged as well as unable to keep the indoor air clean.

본 고안은 상기와 같은 종래의 제반 문제점들을 감안하여, 압력센서로 필터에 걸러진 먼지량을 검출하고 필터에 걸러진 먼지량의 많을 경우에 이를 표시하여 필터의 교환을 지시함은 물론 공기청정기의 구동을 정지시키게 안출한 것으로 이를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention, in view of the conventional problems as described above, by detecting the amount of dust filtered on the filter with a pressure sensor, and displays a large amount of dust filtered on the filter to instruct the replacement of the filter as well as to stop the operation of the air cleaner. The present invention will be described in detail with reference to the accompanying drawings.

첨부된 도면은 본 고안의 필터교환 지시회로도로서 이에 도시된 바와같이 저항(R1, R2) 및 콘덴서 (C1, C2)의 시정수로 발진하는 발진용 집적소자(1)와,상기 발진용 집진소자(1)의 발진신호를 승압하고 배전압 정류하여 집진부로 고압의 집진전압을 출력하는 트랜스(T), 다이오드(D1,DN) 및 콘덴서(C1, CN)로 된 집진전압 출력부(2)와, 팬모타의 구동에 따라 필터를 통과하는 공기의 풍속으로 필터에 걸러진 먼지량을 검출하는 압력센서(SE)와, 상기 압력센서(SE)가 검출한 필터의 먼지량에 따라 필터의 교환을 지시하는 저항(R3, R4), 트랜지스터(TR1) 및 발광 다이오드(LD)로 된 필터교환 표시부(3) 및 상기 발진용 집적소자(1)의 동작전원을 차단하는 저항(R5, R6), 포토카플러(PC) 및The accompanying drawings show a filter replacement instruction circuit diagram of the present invention, and the oscillation integrated device 1 oscillating with time constants of the resistors R 1 and R 2 and the capacitors C 1 and C 2 , as shown in FIG. It consists of a transformer (T), a diode (D 1 , D N ) and a capacitor (C 1 , C N ) for boosting the oscillation signal of the oscillation dust collecting element 1 and rectifying the double voltage to output a high-voltage dust collection voltage to the dust collecting unit. The dust collecting voltage output unit 2, the pressure sensor SE which detects the amount of dust filtered by the filter by the wind speed of air passing through the filter as the fan motor is driven, and the amount of dust of the filter detected by the pressure sensor SE To switch off the operation power of the filter replacement display unit 3 including the resistors R 3 and R 4 , the transistor TR 1 , and the light emitting diode LD and the oscillation integrated device 1. Resistors (R 5 , R 6 ), photocouplers (PC) and

트랜지스터(TR2)로 된 동작전원 차단부(4)로 구성하였다.To the transistor (TR 2) operating power supply was constructed to cut off part (4).

상기에서 압력센서(SE)는 필터에 걸러진 먼지량이 적어 통과하는 공기의 풍속이 빠를 경우에 단락상태로 되고, 먼지량이 많아 공기의 풍속이 느릴 경우에 개방상태로 되며, 도면의 설명중 미설명 부호 Vcc는 동작전원이다.In the above, the pressure sensor SE is short-circuited when the amount of dust filtered by the filter is small, and the air velocity passing through the filter is short. Vcc is the operating power supply.

이와같이 구성된 본 고안은 동작전원(Vcc)이 인가된 상태에서 필터에 걸러진 먼지량이 적어 통과하는 공기의 풍속이 빠르고 압력센서(SE)가 이를 검출하여 단락상태로 되면 동작전원(Vcc)이 압력센서(SE) 및 저항(R4)을 통해 트랜지스터(TR1)의 베이스에 인가되므로 트랜지스터(TR1)가 오프되고, 발광다이오드(LD)가 점등되지 않으며, 또한 동작전원(Vcc)이 압력센서(SE) 및 저항(R5)을 통해 포토카플러(PC)의 포토 다이오드(PD)에 인가되어 그가 발광되고, 수광 트랜지스터(PT)가 온되어 트랜지스터(TR2)가 온되므로 동작전원(Vcc)이 트랜지스터(TR2)를 통해 발진용 집적소자(1)의 전원단자(V)에 인가된다.The present invention configured as described above has a small amount of dust filtered through the filter while the operating power supply (Vcc) is applied, and thus the wind speed of the air passing through is fast and the pressure sensor (SE) detects the short-circuit state. It is applied to the base of transistor TR 1 through SE and resistor R 4 , so transistor TR 1 is turned off, light emitting diode LD is not lit, and operating power supply Vcc is pressure sensor SE. Is applied to the photodiode PD of the photocoupler PC through the resistor R 5 and emits light, and the light receiving transistor PT is turned on so that the transistor TR 2 is turned on. It is applied to the power supply terminal V of the oscillating integrated device 1 via TR 2 .

따라서 발진용 집적소자(1)는 발진되고, 발진 신호는 트랜스(T)에 의해 승압되고 다이오드(D1-DN) 및 콘덴서(C11-C1N)에 의해 배전압 정류되어 집진부로 고압의 집진전압을 출력 즉, 공기청정기는 정상으로 동작하여 실내공기를 청정시키게 된다.Therefore, the oscillation integrated device 1 is oscillated, the oscillation signal is boosted by the transformer T, rectified by the diode D 1 -D N and the capacitor C 11 -C 1N , and the high voltage is collected by the dust collector. The output of the dust collection voltage, that is, the air purifier operates normally to clean the indoor air.

한편, 필터에 걸러진 먼지량이 많아 이를 통과하는 공기의 풍속이 느리고, 압력센서(SE)가 이를 검출하여 개방상태로 되면, 상기와는 반대로 트랜지스터(TR1)의 베이스에 저전위가 인가되어 그가 온되고, 발광 다이오드(LD)가 점등되어 필터의 교환을 지시하며, 또한 포토카플러(PC)의 포토 다이오드(PD)가 점등되지 못하여 포토트랜지스터(PT)가 오프되고, 트랜지스터(TR2)가 오프되므로 발진용 집적소자(1)에 동작전원(Vcc)이 인가되지 않게 된다.On the other hand, if the amount of dust filtered by the filter is slow and the air velocity passing therethrough is low, and the pressure sensor SE detects this and becomes open, a low potential is applied to the base of the transistor TR 1 on the contrary. Since the light emitting diode LD is turned on to instruct the replacement of the filter, and the photodiode PD of the photocoupler PC is not turned on, the phototransistor PT is turned off and the transistor TR 2 is turned off. The operating power source Vcc is not applied to the oscillation integrated device 1.

따라서, 발진용 집적소자(1)의 발진이 정지되고, 집진 전압 출력부(2)가 저전압을 출력 즉, 공기 청정기의 구동이 정지된다.Therefore, oscillation of the oscillation integrated device 1 is stopped, and the dust collection voltage output unit 2 outputs a low voltage, that is, driving of the air cleaner is stopped.

이상에서 상세히 설명한 바와같이 본 고안은 필터에 걸러진 먼지량이 많을 경우에 이를 검출하여 필터의 교환을 지시하고 공기청정기 동작을 정지시키므로 필터에 걸러진 먼지량이 많을 경우에 사용자는 바로 이를 알고 필터를 교환하여 실내공기를 청정하게 유지시킬 수 있고, 또한 소음의 발생을 줄일 수 있을뿐만 아니라 팬모타의 과열을 방지하고 공기 청정기의 사용수명을 연장하게 되는 효과가 있다.As described in detail above, the present invention detects a large amount of dust filtered on the filter, instructs the filter to be replaced, and stops the air purifier operation. It is possible to keep the air clean, and to reduce the generation of noise as well as to prevent overheating of the fan motor and to extend the service life of the air cleaner.
