본 고안은 공기 조화장치의 실내 공기를 자동 조절할 수 있는 장치에 관한 것이다.The present invention relates to a device capable of automatically adjusting the indoor air of the air conditioner.

공기조화장치의 팬 히터(Fan Heater)는 불꽃 감지기인 프레임로드(Frame Rod)가 불완전 연소되는 불꽃에서 유해가스(일산화탄소등)에 대응하는 전류신호를 검출함에 따라 실내 공기의 산소결핍을 감지하고, 에어콘인 경우에는 산소 센서를 이용하여 실내 공기의 산소량을 측정하고 있다.The fan heater of the air conditioner detects oxygen deficiency of indoor air by detecting a current signal corresponding to harmful gas (carbon monoxide, etc.) from a flame incompletely burned by a flame detector, a frame rod. In the case of air conditioners, oxygen is measured in the indoor air using an oxygen sensor.

이러한 방식으로 실내공기를 검출하는 종래의 공기 조화장치는 실내공기의 산소결핍을 감지하였을 때, 팬히터는 연소를 중지하기 때문에 실내공기가 더욱 악화되지 않으나 유해가스의 실외 배출을 위한 근본적 대책이 가욱되지 않은 결점이 있었고, 에어콘인 경우는 실내 공기를 환풍시키기 위해 인위적으로 실내공기를 순환시켜야 하는 불편한 점이 있었다.In the conventional air conditioner that detects indoor air in this way, when the oxygen air is detected in the indoor air, the fan heater stops combustion, so the indoor air is not worsened, but fundamental measures for outdoor discharge of harmful gases are not easy. There was a drawback, and in the case of an air conditioner, there was an inconvenience of artificially circulating indoor air to ventilate the indoor air.

따라서, 본 고안의 목적은 상기한 결점을 해결하기 위해 안출한 것으로, 에어콘의 산소센서 또는 팬히타의 프레임 로드에서 산소결핍을 감지한 신호로 환풍기의 모타를 제어하므로써 실내 공기를 자동으로 조절하는 장치를 제공하는 데 있다.Accordingly, an object of the present invention is to solve the above-mentioned drawback, the device to automatically control the indoor air by controlling the motor of the ventilator by detecting the oxygen deficiency from the oxygen sensor of the air conditioner or the frame rod of the fan heater. To provide.

이하 첨부도면에 의거하여 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부 도면에서, 연산증폭기(OP1)의 입력단자(T)는 팬히타의 프레임로드에서 산소결핍을 감지하여 대응되는 전류가 인가되고, 또는 에어콘의 산소센서에서 감지한 전류가 인가되게 하는 입력단이다.In the accompanying drawings, the input terminal T of the operational amplifier OP 1 is an input terminal for detecting the oxygen deficiency in the frame load of the fan heater so that a corresponding current is applied or a current detected by the oxygen sensor of the air conditioner is applied. .

상기한 입력단자(T)를 통해 인가되는 신호는 증폭용 연산증폭기(OP1)를 거쳐서 전원(Vcc)이 저항(R3)과 가변저항(R4)에 의해 분압된 기준신호와 비교용 연산증폭기(OP2)에서 비교되고, 연산증폭기(OP2)의 출력신호에 의해 원격 제어송신회로(IC1)를 전환시키는 스위치용 트랜지스터(Q1)가 제어되며, 원격제어송신회로(IC1)의 동작여부에 따라 적의선송신용 다이오드(D1)가 도통되게 연결한다.The signal applied through the input terminal T is calculated for comparison with the reference signal divided by the resistor R 3 and the variable resistor R 4 through the amplifying operational amplifier OP 1 . amplifier and compared in (OP 2), an operational amplifier, the switch transistor (Q 1) for being controlled to (OP 2) switching the remote control transmission circuit (IC 1) by the output signal of the remote control transmission circuit (IC 1) Depending on whether the operation of the enemy line diode (D 1 ) is connected to conduct.

그리고, 상기한 다이오드(D1)에서 송신된 적외선을 수신하는 적외선 수신용 다이오드(D2)는 수신된 적외선에 대응하는 전기신호로 변환하여 원격제어 수신회로(IC2)에 인가되게 하여 증폭시키고, 이 원격제어 수신회로(IC2)의 직렬출력신호를 인가하는 시프트레지스터(SR)는 병렬로 출력되게 하여서 병렬출력신호중 하나의 출력신호는 앤드게이드(AND)를 통해 다른 출력신호를 직접 인가하는 비교기(IC3)에서 비교되게 하며, 비교기(IC3)의 출력신호에 의해 릴레이 구동용 트랜지스터(Q2)가 도통되어 릴레이(RY)가 동작되므로써 환풍용 모타(M)가 동작되게 연결한다.In addition, the infrared receiving diode (D 2 ) for receiving the infrared rays transmitted from the diode (D 1 ) is converted into an electrical signal corresponding to the received infrared rays to be applied to the remote control receiving circuit (IC 2 ) and amplified The shift register SR, which applies the serial output signal of the remote control receiving circuit IC 2 , is output in parallel so that one output signal of the parallel output signal is directly applied to the other output signal through the AND gate AND. and to be compared in a comparator (IC 3), the relay driving transistor (Q 2) for by the output signal of the comparator (IC 3) is conductive and the relay (RY) is operating connection doemeurosseo so that the motor (M) for ventilation operation.

이와 같이 구성되는 본 고안에서, 입력단자(T)를 통해 인가되는 산소결핍의 대응되는 전기신호는 미소한 양의 기전력이므로 연산증폭기(OP1)에서 증폭시킨다.In the present invention configured as described above, the corresponding electrical signal of the oxygen deficiency applied through the input terminal T is a small amount of electromotive force and thus amplified by the operational amplifier OP 1 .

상기한 연산증폭기(OP1)의 출력신호는 연산증폭기(OP2)에 인가되는데, 연산증폭기(OP2)의 비반전단자에 인가되는 기준전압은 저항(R3)과 가변저항(R4)에 의해 가변적으로 설정할 수 있는 신호로서 이 증폭신호와 비교된다.The output signal of the one operational amplifier (OP 1) has an operational amplifier there is applied to the (OP 2), the reference voltage applied to the non-inverting terminal of the operational amplifier (OP 2) has a resistance (R 3) and a variable resistor (R 4) It is a signal which can be set variably by this and is compared with this amplified signal.

만일, 산소결핍에 대응하는 신호가 기준신호보다 전압레벨이 낮을 때에는 연산증폭기(OP2)의 출력단에 하이레벨신호가 나타나서 트랜지스터(Q1)를 도통시킨다.If the signal corresponding to the oxygen deficiency has a lower voltage level than the reference signal, a high level signal appears at the output terminal of the operational amplifier OP 2 to conduct the transistor Q 1 .

이때, 원격제어송신회로(IC1)가 동작되면서 적외선 송신용 다이오드(D1)를 도통시켜 적외선이 송신된다.At this time, while the remote control transmission circuit IC 1 is operated, the infrared ray is transmitted by conducting the infrared ray transmitting diode D 1 .

그리고, 상기한 다이오드(D1)에서 송신된 적외선을 수신하는 적외선 수신용 다이오드(D2)는 수신된 적외선에 대응하는 전기신호로 변환하여 원격제어수신회로(IC2)에 인가되게 하여 증폭시키고, 이 원격제어수신회로(IC2)의 적렬출력신호를 인가하는 시프트레지스터(SR)는 병렬로 출력되게 하여서 병렬출신신호중 하나의 출력신호는 앤드게이트(AND)를 통해 다른 출력신호를 직접 인가하는 비교기(IC3)에서 비교되게 하며, 비교기(IC3)의 출력신호에 의해 릴레이 구동용 트랜지스터(Q2)가 도통되어 릴레이(RY)가 동작되므로써 환풍용 모타(M)가 동작되게 연결한다.In addition, the infrared receiving diode (D 2 ) for receiving the infrared rays transmitted from the diode (D 1 ) is converted into an electrical signal corresponding to the received infrared rays to be applied to the remote control receiving circuit (IC 2 ) and amplified The shift register SR, which applies the output signal of the remote control receiving circuit IC 2 , is output in parallel so that one output signal of the parallel output signal directly applies the other output signal through the AND gate AND. and to be compared in a comparator (IC 3), the relay driving transistor (Q 2) for by the output signal of the comparator (IC 3) is conductive and the relay (RY) is operating connection doemeurosseo so that the motor (M) for ventilation operation.

이와같이 구성되는 본 고안에서, 입력단자(T)를 통해 인가되는 산소결핍의 대응되는 전기신호는 미소한양의 기전력이므로 연산증폭기(OP1)에서 증폭시킨다.In the present invention configured as described above, since the corresponding electric signal of oxygen deficiency applied through the input terminal T is a small amount of electromotive force, it is amplified by the operational amplifier OP 1 .

상기한 연산증폭기(OP1)의 출력신호는 연산증폭기(OP2)에 인가되는데, 연산증폭기(OP2)의 비반전단자에 인가되는 기준전압은 저항(R3)과 가변저항(R4)에 의해 가변적으로 설정할 수 있는 신호로서 이 증폭신호와 비교된다.The output signal of the one operational amplifier (OP 1) has an operational amplifier there is applied to the (OP 2), the reference voltage applied to the non-inverting terminal of the operational amplifier (OP 2) has a resistance (R 3) and a variable resistor (R 4) It is a signal which can be set variably by this and is compared with this amplified signal.

만일, 산소결핍에 대응하는 신호가 기준신호보다 전압레벨이 낮을때에는 연산증폭기(OP2)의 출력단에 하이레벨신호가 나타나서 트랜지스터(Q1)를 도통시킨다.If the signal corresponding to the oxygen deficiency has a lower voltage level than the reference signal, a high level signal appears at the output terminal of the operational amplifier OP 2 to conduct the transistor Q 1 .

이때, 원격제어송신회로(IC1)가 동작되면서 적외선 송신용 다이오드(D1)를 도통시켜 적외선이 송신된다.At this time, while the remote control transmission circuit IC 1 is operated, the infrared ray is transmitted by conducting the infrared ray transmitting diode D 1 .

송신된 적외선을 수신하는 다이오드(D2)는 수신된 적외선에 대응하는 전기신호로 변환하여 원격제어수신회로(IC2)에 인가시키고, 이 원격제어 수신회로(IC2)는 입력신호를 증폭하여 시프트레지스터(SR)에 인가시켜서 시프트레지스터(SR)에서 병렬로 출력되게 한다.A diode (D 2) is converted into an electrical signal corresponding to the received infrared ray was applied to the remote control receiving circuit (IC 2), a remote control receiving circuit (IC 2) for receiving the transmitted infrared amplifies the input signal It is applied to the shift register SR so as to be output in parallel from the shift register SR.

이때, 시프트 레지스터(SR)의 병렬 출력신호중 한 신호를 앤드게이트(AND)를 통해 비교기(IC3)에 인가시켜 다른 신호와 비교하게 하는 것은 수신된 적외선에 대응하는 전기신호의 노이즈를 제거하기 위한 것이다.At this time, one of the parallel output signals of the shift register SR is applied to the comparator IC 3 through the AND gate AND to be compared with the other signals to remove noise of the electrical signal corresponding to the received infrared rays. will be.

이와 같이, 비교기(IC3)에서 노이즈를 제거한 수신신호는 트랜지스터(Q2)를 도통시키고, 이와 동시에 릴레이(RY)가 구동되어 환풍용모타(M)는 동작된다.In this way, the received signal from which the noise is removed from the comparator IC 3 conducts the transistor Q 2 , and at the same time, the relay RY is driven to operate the ventilation motor M.

따라서, 환풍용 모타(M)가 동작되면서 실내의 공기를 순환시켜 적절한 수준이 되면, 산소결핍 감지기에서 감지한 전압이 기준전압보다 높아져서 비교용 연산증폭기(OP2)의 출력신호는 로우레벨이 되어 적외선 송수인이 차단되므로서 환풍용 모타가 정지된다.Therefore, when the ventilation motor M is operated and the air in the room is circulated to an appropriate level, the voltage detected by the oxygen depletion detector becomes higher than the reference voltage, and the output signal of the comparison operational amplifier OP 2 becomes low level. As the infrared sender is blocked, the ventilation motor is stopped.

이상과 같이 본 고안에 의하면 공기조화장치의 실내공기를 자동으로 조절하면서 환기시킬 수 있어 실내공기의 산소결핍으로 인한 위험 및 불쾌감을 제거할 수 있다.According to the present invention as described above it can be ventilated while automatically adjusting the indoor air of the air conditioner can remove the risk and discomfort caused by the oxygen deficiency of the indoor air.
