이하, 본 발명에 따른 환기식 시약장을 첨부도면을 참조하여 설명하면 다음과 같다.Hereinafter, the ventilated reagent field according to the present invention will be described with reference to the accompanying drawings.

도 1 은 본 발명에 적용되는 환기식 시약장의 블록도로서, 이를 참조하여 설명하면 다음과 같다.1 is a block diagram of a ventilated reagent field applied to the present invention.

램프스위치(10)가 온(on)되면 램프스위치 온신호를 엔드(AND)게이트(13)의 입력단에 출력하고, 도어3(11c)이 열리면 도어열림감지회로(12)가 도어의 열림을 감지하여 엔드게이트(13)의 입력단에 도어열림 감지신호를 출력하여, 시약장 룸(ROOM3)램프(14)를 점등시킨다. 이때, 룸(ROOM3)램프(14)가 점등되면서 팬(29)도 같이 구동된다. 즉, 도어3이 열릴때에는 램프(14)에 램프 점등신호가 인가되어 램프(14)가 점등되고 동시에 팬(29)에도 팬 구동신호가 인가되어 팬(29)을 구동하게 된다. 이상이 도어3이 열릴때의 램프(14) 및 팬(29)의 동작과정이다.When the lamp switch 10 is turned on, the lamp switch on signal is output to the input terminal of the end gate 13, and when the door 3 11c is opened, the door open detection circuit 12 detects the door open. Then, the door open detection signal is output to the input terminal of the end gate 13, and the reagent chamber room ROOM3 lamp 14 is turned on. At this time, while the room ROOM3 lamp 14 is turned on, the fan 29 is also driven. That is, when the door 3 is opened, a lamp lighting signal is applied to the lamp 14 so that the lamp 14 is turned on and a fan driving signal is also applied to the fan 29 to drive the fan 29. That is the operation of the lamp 14 and the fan 29 when the door 3 is opened.

상기와 같은 방법으로 램프스위치(10)가 온(on)되면 램프스위치 온신호를 엔드게이트(15)의 입력단에 출력하고, 도어6(11f)이 열리면 도어열림감지회로(12)가 도어의 열림을 감지하여 엔드게이트(15)의 입력단에 도어열림 감지신호를 출력하여, 시약장 룸(ROOM6)램프(16)를 점등시킨다. 이때, 룸(ROOM3)램프(16)가 점등되면서 팬(29)도 같이 구동된다. 즉, 도어6이 열릴때에는 램프(16)에 램프 점등신호가 인가되어 램프(16)가 점등되고 동시에 팬(29)에도 팬 구동신호가 인가되어 팬(29)을 구동하게 된다. 이상이 도어6이 열릴때의 램프(16) 및 팬(29)의 동작과정이다. When the lamp switch 10 is turned on in the same manner as described above, the lamp switch on signal is output to the input terminal of the end gate 15, and when the door 6 11f is opened, the door open detection circuit 12 opens the door. Senses and outputs a door open detection signal to the input terminal of the end gate 15 to turn on the reagent room room (ROOM6) lamp (16). At this time, while the room ROOM3 lamp 16 is turned on, the fan 29 is also driven. That is, when the door 6 is opened, a lamp lighting signal is applied to the lamp 16 so that the lamp 16 is turned on and a fan driving signal is also applied to the fan 29 to drive the fan 29. The above is the operation process of the lamp 16 and the fan 29 when the door 6 is opened.

한편, 도어1, 2, 4, 5 가 열릴때에는 팬(29)만 구동된다. 즉, 도어1, 2, 4, 5 가 열릴때에는 램프(14)(16)에 램프 점등신호가 인가되지 않고 팬(29)에만 팬 구동신호가 인가되어 팬(29)을 구동하게 된다. On the other hand, only the fan 29 is driven when the doors 1, 2, 4, 5 are opened. That is, when the doors 1, 2, 4, and 5 are opened, the lamp lighting signal is not applied to the lamps 14 and 16, and the fan driving signal is applied only to the fan 29 to drive the fan 29.

상기 동작과정을 좀더 구체적으로 부연하여 설명하면 다음과 같다.The operation process will be described in more detail as follows.

도어열림 감지시 도어열림감지회로(12)에서 도어열림 감지신호를 오아(OR)게이트(23)에 출력하고, 사람이 시약장에 접근하여 도어를 열려고 할때 인체감지센서(17)에서 이를 감지하여 그 감지신호를 오아게이트(23)에 출력하며, 시약장 내에 보관중인 약품들 중에서 유해가스가 발생되거나 역한 냄새 등이 발생되어 다른 약품에 영향을 주어 약품이 오염되면 오염센서(18)가 이를 감지하고 오염센서(18)를 통해 오염상태를 입력받은 오염레벨 측정 및 비교기(19)에서 오염의 정도(레벨)를 측정, 비교하여 오염의 일정 기준치를 초과하면(오염레벨이 높으면) 오아게이트(23)에 출력하며, 팬 '강' 스위치(20)를 온시키고 팬 온 타이머(21)를 구동시켜 그 두 신호(스위치 온 및 타이머 구동신호)를 엔드게이트(22)에 출력하여, 상기 입력된 신호들을 조합하여 엔드게이트(23)에서 하나의 신호로 출력한다.When the door open detection, the door open detection circuit 12 outputs the door open detection signal to the OR gate 23, and when a person approaches the reagent field and tries to open the door, the human body sensor 17 detects this. The detection signal is output to the oragate 23, and harmful gases are generated or adverse smells are generated among the chemicals stored in the reagent room, which affects other chemicals. The pollution level measurement and comparator 19 which receives the contamination state through the pollution sensor 18 measures and compares the degree of contamination (level), and when the predetermined threshold value of contamination is exceeded (if the contamination level is high), the oragate 23 And the fan 'strong' switch 20 is turned on and the fan on timer 21 is driven to output the two signals (switch on and timer drive signals) to the end gate 22 to output the input signals. In combination with the endgate ( 23) and output as one signal.

상기 엔드게이트(23)의 출력신호가 릴레이(24)에 입력되어 릴레이(24)가 작동(릴레이(24)의 스위치가 N.O(Normal Open)상태가 됨)됨과 동시에 릴레이(24)에 연결된 팬(29)이 '강' 으로 작동되어 팬(29)의 모터가 강하게 회전하여 유해가스가 실내로 유출되지 않고 외부로 배출되게 된다.The output signal of the end gate 23 is input to the relay 24 so that the relay 24 is operated (the switch of the relay 24 is in a normal open state) and a fan connected to the relay 24 ( 29) is operated by the 'strong' so that the motor of the fan 29 is strongly rotated so that noxious gas is discharged to the outside instead of the room.

주기적으로 온/오프되는 팬 온/오프 스위치(25)가 온되어 엔드게이트(27)에 출력하고, 팬 온/오프 반복 타이머(26)가 온되어 엔드게이트(27)에 출력하며, 엔드게이트(27)에서 그 두 신호(팬 온 스위치 신호 및 타이머 온 신호)를 조합하여 하나의 신호로 릴레이(28)에 인가함으로서 릴레이(28)를 작동(이때 릴레이(24)는 N.C(Normal Close)가 상태가 되고 릴레이(28)가 온됨)함과 동시에 릴레이(28)에 연결된 팬(29)이 '약' 으로 작동되어 팬(29) 모터가 회전하게 된다.The fan on / off switch 25 periodically turned on and off is output to the end gate 27, and the fan on / off repeat timer 26 is turned on and output to the end gate 27, and the end gate ( 27) operates the relay 28 by combining the two signals (fan on switch signal and timer on signal) to the relay 28 as one signal (in this case, the relay 24 is in the state of NC (normal close)). And the relay 28 is turned on) and at the same time the fan 29 connected to the relay 28 is operated 'about' so that the fan 29 motor rotates.

한편, 교류(AC)전원부(30)는 상기 릴레이(24)(28)와 팬(29)에 전원을 공급한다.The AC power supply unit 30 supplies power to the relays 24 and 28 and the fan 29.

상기 본 발명의 주요 포인트는, 램프(14)(16)는 램프스위치(10)가 온되어 있고 도어3(11c)과 도어6(11f)이 열려야만 온이 된다.The main point of the present invention is that the lamps 14 and 16 are turned on only when the lamp switch 10 is turned on and the doors 311c and 6f are opened.

또한, 팬(29)은 도어(11)가 열리거나 인체감지가 되거나 팬(29)의 '강' 스위 치(20)가 온되거나 오염레벨이 높으면 팬(29)이 강하게 회전하고, 주기적으로 팬(29)이 회전하는 스위치(25)만 온되면 팬(29)이 약하게 회전하게 된다.In addition, the fan 29 is the door 29 is opened or the body is detected, the 'strong' switch 20 of the fan 29 is turned on or the pollution level is high, the fan 29 is strongly rotated, the fan periodically If only the switch 25 on which the 29 is rotated is turned on, the fan 29 is weakly rotated.

이상에서 설명한 바와같이, 본 발명은 평상시에는 팬의 모터가 일정시간 약하게 회전하다가 도어를 열면 팬 모터를 강하게 회전시킴으로서 유해가스가 실내로 유출되는 것을 방지하게 되는 효과를 가져온다.As described above, the present invention has an effect of preventing harmful gas from leaking into the room by normally rotating the fan motor while the fan motor rotates weakly for a predetermined time and strongly rotating the fan motor.
