본 고안은 선풍기에서 저속으로도 고속과 같은 기동토크를 갖게한 전자회로 속도 조절장치의 구성 개량에 관한 것이다.The present invention relates to an improvement of the configuration of an electronic circuit speed control device that has a starting torque such as high speed even at a low speed in a fan.

종래 전자회로를 사용한 선풍기 속도 조절장치는 제1도와 같이 모터의 권선단자를 트라이악(T1,T2,T3)으로 전환토록 되어 있으나, 저속으로 선풍기를 기동할 때에는 기동시간이 길뿐 아니라, 기동토크의 부족으로 인한 기동불량이 발생하는 경우가 많았다.Fan speed control device using a conventional electronic circuit is to switch the winding terminal of the motor to the triac (T 1 , T 2 , T 3 ) as shown in Fig. 1 , the start time is not only long when starting the fan at low speed, In many cases, poor start-up occurred due to a lack of starting torque.

본 고안은 이와같은 점을 감안하여 저속 기동시 모터의 고속용 권선에도 전원이 공급되도록 하여 저속시의 기동이 정확하고 또 단시간에 저속 회전 속도에 도달하게한 것이다.In view of the above, the present invention allows power to be supplied to the high-speed winding of the motor at low speed, so that the start at low speed is accurate and the low speed rotation is reached in a short time.

본 고안의 구성을 설명하면 다음과 같다.The configuration of the present invention is as follows.

제2도와 같이 전자회로(1)에 의해 모터(M)의 속도를 제어토록된 선풍기에서 도시되지 않은 통상의 자동 정지장치와 연결되는 트랜지스터(TR1)의 콜렉터와 에미터간에 접속된 콘덴서(C1)의 일측은 저항(R4)과 다이오드(D1)를 통해 저속단자(A)에, 또 다이오드(D3)를 거쳐 전원(V+)에 연결하고, 다이오드(D1)의 캐소드에서 저항(R1)을 통해 트라이악(T1)의 게이트에 접속하며, 콘덴서(C1)의 타측은 트라이악(T3)의 게이트에, 저항(R3)과 다이오드(D2)를 거쳐 고속단자(C)에 각각 연결하고, 중속단자(B)에서 저항 (R2)을 거쳐 트라이악(T2)의 게이트에 접속하여서된 것이다.The capacitor C connected between the collector and the emitter of the transistor TR 1 , which is connected to a normal automatic stop device not shown in the fan, by which the electronic circuit 1 controls the speed of the motor M as shown in FIG. 2 . One side of 1 ) is connected to a low speed terminal A via a resistor R 4 and a diode D 1 , and to a power supply V + via a diode D 3 , and a resistor at the cathode of the diode D 1 . (R 1 ) is connected to the gate of the triac T 1 , and the other side of the capacitor C 1 is connected to the gate of the triac T 3 via a resistor R 3 and a diode D 2 . It is connected to the terminal C, respectively, and is connected to the gate of the triac T 2 through the resistor R 2 at the medium speed terminal B.

미설명부호 R5,R6,R7는 게이트 보호저항, AC 100V는 교류전원, D는 트랜지스터의 베이스로서 도시되지 않은 날개에 손이 닿으면 선풍기가 자동정지되게한 자동 정지장치의 출력에 접속된 것이다.Unmarked R 5 , R 6 and R 7 are the gate protection resistors, AC 100 V is the AC power supply, D is the base of the transistor, and D is connected to the output of the automatic stop device which causes the fan to automatically stop when the blade touches an unshown wing It is.

이와같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

선풍기를 중속 혹은 고속으로 기동할 때에는 도시되지 않은 해당버튼을 누르면 전자회로(1)의 중속단자(B) 혹은 고속단자(C)가 하이(H)레벨이 되므로 트라이악(T2) 혹은 (T3)이 도통되어 모터(M)가 통상과 같이 중속 혹은 고속으로 기동된다.When starting the fan at medium speed or high speed, press the corresponding button (not shown) to bring the medium speed terminal B or the high speed terminal C of the electronic circuit 1 to the high level so that the triac T 2 or T 3 ) is turned on and the motor M is started at medium speed or high speed as usual.

선풍기를 저속으로 기동할 때에는 저속단자(A)가 하이(H)레벨이 되므로 그 상승에지에서 다이오드(D1)→저항(R4)→콘덴서(C1)→트라이악(T3)의 게이트로 콘덴서(C1)의 충전 전류가 흘러 트라이악(T3)이 도통되고 동시에 다이오드(D1)→저항(R1)→트라이악(T1)의 게이트로 바이어스 전류가 흘러 트라이악(T1)이 도통되므로 모터(M)는 일단 고속상태로 기동하게 되고, 잠시후 콘덴서(C1)의 충전이 완류되면 큰덴서(C1)에는 충전 전류가 흐르지 않게 되므로 트라이악(T3)의 게이트 전류가 없어져서 트라이악(T3)은 차단되고 트라이악(T1)만 도통되어 모터(M)는 저속상태로 회전을 계속하게 되므로 저속 기동시에도 고속에서와 같이 기동되는 것이다. 이때 다이오드(D1,D2)는 각각 저속, 고속의 전환시 콘덴서(C1)를 통해 전자회로(1)에 유입되는 역전류를 방지하여 전자회로(1)를 보호하는 작용을 하게된다. 선풍기를 정지시키거나 교류전원(AC 100V)이 차단되면 전원(V+)이 접지 전위로 되므로 콘덴서(C1)에 충전된 전하는 다이오드(D3)를 통해 순간적으로 모두 방전되어 버리므로 이상태에서 다시 교류전원이 들어오더라도 상기와 같은 작용으로 저속상태에서 선풍기가 기동되게 되며 또한 사용자의 안전사고를 방지하기 위한 자동정지 장치가 내장된 선풍기에서 사고시 자동정지 장치가 작동되면 그 출력(D)이 하이(H)레벨로 되어 이에 접속된 트랜지스터(TR1)의 에미터, 콜렉터간이 도통되므로 콘덴서(C1)의 전하를 모두 방전시켜 사용자가 다시 저손상태에서 선풍기를 기동할 때 기동 보상회로가 확실하게 작동토록되어 있다.When starting the fan at low speed, the low speed terminal (A) becomes the high (H) level, so at the rising edge, the gate of the diode (D 1 ) → resistance (R 4 ) → capacitor (C 1 ) → triac (T 3 ) The charging current of the capacitor (C 1 ) flows to the triac (T 3 ) and conducts a bias current to the gate of the diode (D 1 ) → resistance (R 1 ) → triac (T 1 ). 1) the conductive since the motor (M) is one end becomes activated in the high-speed state, while since after the capacitor (when charging is wanryu large condenser (C 1), the stops flowing a charging current of C 1), the triac (T 3) The triac T 3 is blocked because the gate current is lost, and only the triac T 1 is turned on so that the motor M continues to rotate at a low speed, so that the motor starts as at high speed even at low speed. At this time, the diodes D 1 and D 2 serve to protect the electronic circuit 1 by preventing reverse current flowing into the electronic circuit 1 through the capacitor C 1 during the switching of the low speed and the high speed, respectively. When the fan is stopped or the AC power supply (AC 100V) is cut off, the power supply (V +) becomes the ground potential, so the charges charged in the capacitor (C 1 ) are all discharged momentarily through the diode (D 3 ). Even when the power is turned on, the fan is started at low speed due to the above-mentioned action. Also, if the fan is built in an accident in the fan with an automatic stop device to prevent the user's safety accident, the output (D) becomes high ( H) level is connected between the emitter and the collector of the transistor (TR 1 ) connected to it, so that all the charge of the capacitor (C 1 ) is discharged, the start compensation circuit operates reliably when the user starts the fan in a low damage state again It's all there.

이와같이 본 고안은 간단한 장치로서 선풍기를 저속으로 기동할때 기동불량이 없을뿐 아니라 신속하게 회동되어 기동시간도 단축되는 것이다.In this way, the present invention is a simple device, when the fan is started at low speed, there is no start-up failure and the start-up time is shortened.
