약탕기의 전자식 타이머Electronic timer of shaker

제1도는 본 고안 타이머의 설명도.1 is an explanatory diagram of the present invention timer.

제2도는 본 고안 타이머의 상세한 회로도.2 is a detailed circuit diagram of the present invention timer.

본 고안은 약탕기의 전자식 타이머에 관한 것으로, 특히 일정시간동안 작동되었다가 일정한 시간동안 작동이 되지 않게하는 상태를 연속 반복하다가 원하는 시간에 완전히 정지할 수 있게한 전자식 타이머회로에 관한 것이다.The present invention relates to an electronic timer of a shaker, and more particularly, to an electronic timer circuit that can be stopped at a desired time while repeatedly performing a state that is operated for a certain time, but not operated for a certain time.

종래의 타이머는 기계식(태엽식이나 전동기등)으로 ON과 OFF를 시키므로 조종하기가 어렵고 부피가 크며 기계구성이 복잡하여 고장이 많으며 또 중량이 무거우며 미리 설정한 시간동안 작동되었다가 설정시간이 지나면 작동을 완전히 중지하도록 되어 있어서 연속반복 작용하기가 부적합한 것이었다.Conventional timers are mechanical (spring or electric motors) that turn on and off, making it difficult to control, bulky, and complex in machine configuration, causing many breakdowns, heavy weights, and operating for a preset time. It was not suitable for continuous repetitive action because it was supposed to stop operation completely.

본 고안은 이러한 종래의 단점을 감안하여 기계적 구성이 전혀 없으며 마모성이 없고 ON과 OFF의 동작을 임의로 설정하여 조작할 수 있으며 반영구적이고 고장이 없으며 시간 또한 정확하게 동작할 수 있도록 한 것이다.The present invention has no mechanical configuration, wear-free, and can be operated by setting the ON and OFF operations arbitrarily in consideration of these conventional disadvantages.

이상과 같은 목적을 달성하기 위한 본 고안을 첨부된 도면에 따라 상세히 설명하면 다음과 같다.The present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

먼저 제1도는 본 고안의 블럭 구성도로 전원부(S)의 전원은 무안정 발진기를 구성하는 집적회로(IC1)와 10분주 표시회로를 구성하는 집적회로(IC2) 및 쌍안정 플립-플롭회로(F) 및 리레이(RL)에 공급되며, 집적회로(IC1)에서는 콘덴서(C3)와 가변저항(VR1및 VR2)의 시정수로 무안정 발진하고 그 출력은 집적회로(IC2)에서 10분주하여 쌍안정 발진기를 동작시키도록 되어 있으며 집적회로(IC1, IC2)가 동작하는 동안 리레이(R.L)가 동작하여 스위치 역할을 하게 되어 있다.1 is a block diagram of the present invention, the power supply of the power supply unit S includes an integrated circuit IC 1 constituting an unstable oscillator, an integrated circuit IC 2 constituting a 10-division display circuit, and a bistable flip-flop circuit. (F) and the relay RL, and the integrated circuit IC 1 oscillates unstable with time constants of the capacitor C 3 and the variable resistors VR 1 and VR 2 , and its output is an integrated circuit IC. 2 ), the bistable oscillator is operated by 10 minutes, and the relay RL is operated to act as a switch while the integrated circuits IC 1 and IC 2 are operated.

상기와 같은 본 고안을 제2도의 상세한 전자식 타이머회로를 참고하여 동작을 설명한다.The operation of the present invention as described above with reference to the detailed electronic timer circuit of FIG.

전원트랜스(T)의 2차측에는 다이오드(D1, D2)에 의해 정류된 것을 제너다이오드(ZD)에 의해 정전압(定電壓)회로를 구성하고 집적회로(IC1)는 콘덴서(C3)와 가변저항(VR1, VR2)의 시정수에 따라 발진하는 무안정 바이브레터로 그 일주기가 ON, OFF시간이 되도록 하였으며 집적회로(IC2)는 10진 계수표시를 0-9까지 표시할수가 있게 되어있다.On the secondary side of the power supply T, the rectified by the diodes D 1 and D 2 constitute a constant voltage circuit by the zener diode ZD, and the integrated circuit IC 1 is the capacitor C 3 . And the unstable vibrator that oscillates according to the time constants of the variable resistors (VR 1 and VR 2 ), so that one cycle is ON and OFF time.The integrated circuit (IC 2 ) displays decimal count display from 0-9. I can do it.

또 쌍안정 플립-플립회로(F)는 트랜지스터(TR1, TR2)에 의해 쌍안정바이브레타를 구성시켜 그 출력으로 집적회로(IC1, IC2)의 리세트단자에 연결시켜 리세트하도록 되어 있으므로 트랜지스터(Tr1)의 ON상태일때 트랜지스터(Tr)2는 OFF상태가 되어 타이머는 정지상태가 된다.In addition, the bistable flip-flip circuit F forms a bistable vibrator by transistors TR 1 and TR 2 , and its output is connected to the reset terminal of the integrated circuits IC 1 and IC 2 so as to be reset. Therefore, when the transistor Tr 1 is in the ON state, the transistor Tr 2 is turned OFF and the timer is stopped.

따라서 트랜지스터(Tr2)의 콜렉터와 전원사이에 연결된 콘덴서(C4)는 전원투입시 충전전류에 의해 트랜지스터(Tr2)에 신호를 가하여 정지상태를 유지시킨다.Therefore, the capacitor C 4 connected between the collector of the transistor Tr 2 and the power supply applies a signal to the transistor Tr 2 by the charging current when the power is turned on to maintain the stopped state.

또한 집적회로(IC1)의 출력은 트랜지스터(Tr3)로 전류를 증폭하여 릴레이(R.L)를 동작시키고 이때 스타트 스위치인 푸쉬보턴 스위치(Sw)를 눌러주면, 트랜지스터(Tr1, Tr2)는 역전되어 이번에는 트랜지스터(Tr1)는 ON에서 OFF가 되고 트랜지스터(Tr2)는 OFF에서 ON으로 바뀌어 집적회로(IC1, IC2)의 리세트단자의 동작신호가 되어 릴레이(R.L)가 ON. OFF를 반복하게 된다.In addition, the output of the integrated circuit IC 1 amplifies the current to the transistor Tr 3 to operate the relay RL. At this time, when the push button switch Sw, which is a start switch, is pressed, the transistors Tr 1 and Tr 2 are This time, the transistor Tr 1 turns from ON to OFF, and the transistor Tr 2 turns from OFF to ON to become the operation signal of the reset terminal of the integrated circuits IC 1 and IC 2 so that the relay RL is turned ON. . OFF will be repeated.

또 집적회로(IC1)의 출력은 집적회로(IC2)의 입력단자에 연결되어 있어서(집적회로(IC2)는 집적회로(IC1)의 주파수를 1배에서 10여배까지 분주하여 각 출력단자에 신호가 순차적으로 나타난다.In addition the output of the integrated circuit (IC 1) is an integrated circuit is linked to the input terminal of the (IC 2) (the integrated circuit (IC 2) is an integrated circuit (IC 1, each of the output by dividing the frequency from 1 times 10 yeobae a) Signals appear sequentially at the terminals.

따라서 희망하는 단자에 절환스위치(SW1)를 맞추어 놓으면 그 시간에 신호가 쌍안정 플립-플롭회로(F)의 트랜지스터(Tr1)의 베이스에 다이오드(D3)를 통해 바이어스 전압이 인가되어 트랜지스터(Tr1)은 OFF에서 ON으로 바뀌고 반대로 트랜지스터(Tr2)는 ON에서 OFF로 바뀜으로서 집적회로(IC1, IC2)의 리세트단자에 역신호가 걸리므로 정지상태가 되고 트랜지스터(Tr)4가 도통됨으로서 콜렉터-전원사이에 저항(R4)과 직열연결된 발광다이오드(LED)가 집적회로(IC1, IC2)의 동작상태를 표시하게 된다.Therefore, if the switching switch SW 1 is set to a desired terminal, at that time, a signal is applied to the base of the transistor Tr 1 of the bistable flip-flop circuit F through the diode D 3 , thereby providing a transistor. (Tr 1 ) changes from OFF to ON, and on the contrary, the transistor Tr 2 changes from ON to OFF, so that the reset signal of the integrated circuits IC 1 and IC 2 is inverted, and thus the transistor Tr is stopped. As 4 is conducted, the light emitting diode LED connected in series with the resistor R 4 between the collector and the power supply indicates the operating state of the integrated circuits IC 1 and IC 2 .

집적회로(IC1, IC2)가 동작하게 되면 그 신호가 트랜지스터(Tr3)의 베이스에 인가됨으로서 트랜지스터(Tr3)가 도통되어 릴레이(RL)를 동작시키므로 릴레이 접점을 ON, OFF 되게하여 약탕기의 히터전원을 제어함으로서 타이머의 작동을 하게되는 것이다.Integrated circuits (IC 1, IC 2) that when the operation that the signal transistor (Tr 3) by being applied to the base of the transistor (Tr 3) is because the conductive operating a relay (RL) to be the relay contact ON, OFF yaktanggi By controlling the heater power of the timer is to operate.

따라서 이와같은 본 고안을 약탕기에 사용함으로서 중량이나 복잡성 및 고장율을 줄이고 반영구적으로 사용할수가 있는 것임은 당분야에 종사하는 사람이면 쉽게 이해가 될 것이다.Therefore, it can be easily understood by those skilled in the art that the present invention can be used semi-permanently while reducing weight, complexity, and failure rate by using the present invention in a bath.
