본 고안은 냉장고 콤프레셔의 기동장치에 관한 것이다.The present invention relates to a starting device of a refrigerator compressor.

종래 냉장고용 콤프레셔를 기동시키고져 하는 경우 전동기를 이용해야하며 이와같은 전동기에는 주권선과 기동권선이 있어서 전동기를 기동시킨 뒤 일정 도르크에 이르면 자체권선에서의 역기전류가 발생하여 전동기를 소손시키는 예가 많을 뿐 아니라 50-60HZ의 교류를 사용하는 것이므로 정전되었다가 다시 전류가 흐르는 경우 많은 전류가 전동기에 흐를뿐 전동기에 걸려 있는 부하, 즉 콤프레셔가 연결되어 있어서 전동기가 기동되지 않아 소손등의 고장의 원인이 되며, 또 동작중에도 기동권선에 약간의 전류가 흐르므로 전력의 손실이 많은점등의 결점이 있었던바 본 고안은 이와같은 종래의 결점을 완전해소 하고자하는데 목적이 있다.In order to start a conventional compressor for refrigerators, an electric motor must be used. Such motors have a main winding and a starting winding. When the motor is started and a certain dock is reached, a counter current is generated in its own winding to burn out the motor. In addition, since 50-60HZ of alternating current is used, a large amount of current flows to the motor when a power failure occurs and then the current flows again. In addition, since some current flows in the starting winding during operation, there is a defect such as a lot of power loss, and the present invention aims to completely solve such a conventional defect.

따라서 종래 과전류릴레이 또는 과전류제한기등을 수입에 의존하고 있음을 감안하여 이와같은 문제까지도 완전 해결한 것이다.Therefore, this problem is completely solved in consideration of the conventional overcurrent relay or overcurrent limiter depending on imports.

이하 본 고안을 첨부된 도면에 따라 상술한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안을 설명키 위한 사시도로 갑체(1)에는 덮개(2)로 닫을 수 있도록 되었으며, 상기한 덮개(2)에는 갑체(1) 내부에 설치되는 터미날(3, 3', 3")와 대응되게 구멍(14, 14', 14")이 천공되어 외부의 도시하지 않은 도선을 연결할 수 있도록 되었으며, 상기한 터미널(3, 3', 3")는 갑체(1) 밖으로 돌출되는 연결단자(3-1, 3-2,3-3)와 전기적으로 연결되어 갑체(1)에서 삽탈할 수 있도록 되었으며, 또 상기한 연결단자(3-1, 3-2, 3-3)를 통해 도시하지 않은 콘넥터를 통해 전기적으로 연결되도록 되어 있다.Figure 1 is a perspective view for explaining the present invention is to be closed with a cover (2) on the upper body (1), the terminal (3, 3 ', 3 "installed in the upper body (1) to the cover (2) Holes 14, 14 ', and 14 "are drilled to correspond to the wires (not shown), and the terminals (3, 3', 3") protrude out of the upper body (1). It is electrically connected to the terminals 3-1, 3-2 and 3-3 so that it can be inserted and removed from the body 1, and through the above-described connection terminals 3-1, 3-2 and 3-3. It is to be electrically connected through a connector (not shown).

또 갑체(1)내의 일측에는 제6도 (a)로 도시된 전기적 회로도를 갖는 회로기판(12)이 설치되고, 중앙에는 권선 저항(11)이 위치되며 칸막이(15)가 된 속에는 제3-제5도에 도시된 바와같은 전류제한기(4)가 설치되어 있다.In addition, a circuit board 12 having an electrical circuit diagram shown in FIG. 6 (a) is installed at one side of the body 1, and a winding resistor 11 is positioned at the center thereof, and a partition 15 is placed in the third body. A current limiter 4 as shown in FIG. 5 is provided.

즉 상기한 전류제한기(4)는 제3도의 해탈사시도에 도시된 바와같이 환요홈(13)에는 히-터선(6)이 설치되며 그 위에 바이메탈(7)이 얹혀지고 단자(10)로 구멍(10')에 일측이 고정된 가동편(8)이 고정되었으며 가동편(8)의 타측 접점(9)는 전류제한기(4)의 고정접점(9-1)에 당접되도록 되어 있다.That is, the current limiter 4 has a heater wire 6 installed in the groove 13 as shown in the desorption perspective of FIG. 3, and a bimetal 7 is placed thereon and a hole through the terminal 10. The movable piece 8 having one side fixed to 10 'is fixed, and the other side contact 9 of the movable piece 8 is brought into contact with the fixed contact 9-1 of the current limiter 4.

또 전류제한기(4)의 양측면에는 돌기(5)가 돌설되어 갑체(1) 내측면에 대항되게 요설된 요구(1')에 삽입하여 전류제한기(4)가 갑체(1)내에서 요동되지 않도록 된 것이다.On both sides of the current limiter 4, the projections 5 protrude and are inserted into the request 1 ', which is concave against the inner surface of the body 1 so that the current limiter 4 swings in the body 1. It is not to be.

도면중 미설명부호 8'는 가동편(8)의 볼록부를 의미한다.In the figure, reference numeral 8 'denotes a convex portion of the movable piece 8.

또 상기한 회로기판(12)을 설명하기 전에 종래 공지의 회로를 제6도(a)에 도시했다. 즉 전동기(M)의 주권선(R)과 기동코일(S)은 공통답자(C)에 일측에 연결되고, 주권선(R)의 타측은 스위치(SW)를 통해 교류입력단자(L1)에 연결되고 상기한 공통단자(C)는 연결단자(3-1)와 발열선(6)을 통해 연결단자(3-3)와 바이메탈(7)로 연결되고 바이메탈(7)의 접점은 연결단자(3-2)를 통해 교류 입력단자(L2)에 연결되어 있다.Before describing the circuit board 12 described above, a conventionally known circuit is shown in FIG. In other words, the main winding (R) and the starting coil (S) of the motor (M) is connected to the common answer (C) on one side, the other side of the main winding (R) through the switch (SW) AC input terminal (L 1 ) The common terminal C is connected to the connection terminal 3-3 and the bimetal 7 through the connection terminal 3-1 and the heating line 6, and the contact point of the bimetal 7 is connected to the connection terminal ( It is connected to the AC input terminal L 2 through 3-2).

한편 일측이 공통단자(C)에 연결된 기동권선(S)의 타측은 PTC 저항을 통해 교류입력단자(L1)에 연결되어있다.On the other hand, the other side of the starting winding S, one side of which is connected to the common terminal C, is connected to the AC input terminal L 1 through a PTC resistor.

따라서 스위치(SW)를 ON 시키면 기동권선(S)에는 콘덴서(C1)은 PCT 저항에 의한 높은 전압이 흘러 전동기(M)는 기동되며 역기 전류에 의해 과전류가 PTC 저항을 통해 흐르게 되면 정온도특성에 따라 PTC저항은 급격히 상승하여 제7도에 도시된 바와같이 기동시에 흐르던 전류가 점차 떨어져 내려간다.Therefore, when the switch SW is turned ON, the capacitor C 1 flows to the start winding S, and the motor M is started. When the overcurrent flows through the PTC resistor, the constant temperature characteristic As a result, the PTC resistance rapidly rises, and as shown in FIG. 7, the current flowing at startup gradually falls.

예를들어 기동시 7암페어의 전류는 PTC 특성에 따라 10밀리 암페어의 전류로 하강하여 기동권선(S)의 소손을 방지하나 미세하나마 계속하여 기동권선에 전류가 흐르므로 이와같이 흐르는 전류만큼은 전력손실을 가져오게 되는 것이며 또 off 했다가 ON 하는 경우 PTC 저항이 냉각되는 시간만큼 지연되었다가 ON되는 결점이 있다.For example, at start-up, the current of 7 amps drops to a current of 10 milliamps according to the PTC characteristic to prevent burn-out of the starting winding (S), but the current flows through the starting winding in a minute. In addition, there is a drawback of turning off and turning on the PTC resistor after the cooling time.

이를 시정코져하는 본 고안 회로기판(12)에 설치된 본 고안의 회로도가 제6도(b)에 도시되어 있다. 즉 스위치(SW)와 기동권선(S)사이에는 권선저항(11)과 브리지정류회로(BD)가 연결되었으며, 상기한 브리지정류회로(BD)의 출력측 사이에는 실리콘제어정류소자(SCR)과 다이오드(D1)가 직열연결되고, 상기한 실린콘제어정류소자(SCR)의 게이트에는 에미터 접지된 트랜지스터(TR)의 콜렉터가 연결되고 트랜지스터(TR)의 베이스에는 저항(R1)과 콘덴서(C2) 및 저항(R3)으로 타이머회로가 구성되고 저항(R2) 및 다이오드(D2)가 직열연결되어 전동기(M)의 공통단자(C)와 연결되는 터미널(3)에 연결되고, 티미널(3)과 터미날(3")사이에는 히-터선(6)이 연결되고, 터미널(3")과 터미널(3')사이에는 가동편(8)이 연결되고 상기한 가동편(8)과 히-터선(6)사이에 바이메탈(7)이 설치된 앞서 설명한 전류제한기(4)를 구성하여서 된 것이다. 도면중 R3, R4는 저항, C2는 콘덴서를 의미한다.The circuit diagram of the present invention installed on the inventive circuit board 12 correcting this is shown in FIG. 6 (b). That is, the winding resistor 11 and the bridge rectifier circuit BD are connected between the switch SW and the start winding S, and the silicon control rectifier SCR and the diode are connected between the output side of the bridge rectifier circuit BD. (D 1 ) is connected in series, and the collector of the transistor TR having an emitter ground is connected to the gate of the silicon control rectifying element SCR, and the resistor R 1 and the capacitor (R 1 ) are connected to the base of the transistor TR. C 2 ) and a resistor (R 3 ) consisting of a timer circuit and a resistor (R 2 ) and a diode (D 2 ) is connected in series with the terminal (3) connected to the common terminal (C) of the motor (M) The heater wire 6 is connected between the terminal 3 and the terminal 3 ", and the movable piece 8 is connected between the terminal 3" and the terminal 3 'and the movable piece ( The current limiter 4 described above with the bimetal 7 installed between the 8 and the heater wire 6 is constructed. In the drawings, R 3 and R 4 represent a resistor and C 2 represents a capacitor.

상기와 같은 회로구성으로 되는 것이므로 스위치(SW)를 ON하는 경우 기동권선(S)에는 콘덴서(C1)와 또 권선저항(11)과 브리지정류회로(BD)를 통해 전류가 흐르므로 전동기는 기동됨과 동시 다이오드(D2)에 의해 반파 정류된 전압은 저항(R2)을 통해 콘덴서(C2)를 충전하게 되며 저항(R1)과의 시정수에 의해 트랜지스터(TR)의 베이스에 트리거 전압을 인가하므로서 트랜지스터(TR)의 콜렉터-에미터 사이가 도통됨으로서 실리콘 제어정류소자(SCR)의 에미트를 다시 트리거하여 실리콘제어정류소자(SCR)와 다이오드(D1)는 도통되어 브리지 정류회로(BD)의 출력측에 흐르는 전류는 제8도에 도시한 바와같이 급작이 "0"으로 떨어지게 되고 기동권선(S)에는 아무런 전류가 흐르지 않게되며 스위치(SW)를 OFF하는 경우 저항(R3)에 의해 콘덴서(C2)의 충전전압은 즉시 방전되며, 일단 통전되었던 실리콘제어정류소자(SCR)도 직열연결된 다이오드(D1)와의 전위차(예로 0.7볼트)에 의해 완전 불통되어 브리지정류회로(BD)의 출력측이 개방되어 스위치(SW)를 ON하는경우 즉시 기공이 가능하며 또한, 브리지정류회로(BD)의 출력측이 실리콘제어정류소자(SCR)에 의해 숏트되더라도 권선저항(11)이 연결되어 쇼트 즉시 발열되어 저항이 급격이 상승하여 보호하게 되는 것이다.Since the circuit configuration is as described above, when the switch SW is turned on, current flows through the capacitor C 1 and the winding resistor 11 and the bridge rectifier circuit BD in the starting winding S. soon as the same time diode trigger voltage to the base of the transistor (TR) by a half-wave rectified voltage by the (D 2) is to charge a capacitor (C 2) via a resistor (R 2) with a time constant of the resistance (R 1) When the collector-emitter of the transistor TR is conducted by applying, the trigger of the silicon-controlled rectifier SCR is again triggered so that the silicon-controlled rectifier SCR and the diode D 1 are turned on to form a bridge rectifier circuit ( As shown in FIG. 8, the current flowing to the output side of the BD) drops suddenly to " 0 " and no current flows in the starting winding S. When the switch SW is turned off, the resistance R 3 by charging voltage of the capacitor (C 2) is immediately room And, once the silicon control rectifying element was energized chair (SCR) is also direct thermal potential difference between the associated diode (D 1) (for example 0.7 volt) is completely disrupted by open the output side of the bridge rectifier (BD) to turn ON the switch (SW) In this case, the pore is possible immediately, and even if the output side of the bridge rectifier circuit BD is shorted by the silicon control rectifier element SCR, the winding resistance 11 is connected to generate a short instant, thereby rapidly increasing the resistance to protect. .

상기와 같이 연결된 상태에서 콤프렛셔를 구동시키기 위하여 전동기(M)에 전원을 일정 토르크에 도달하는 경우 전동기의 주권선에는 과전류가 흐르게 되고, 이에따라 터미널(3)과 터미널(3")사이에 연결된 히-터선(6)도 발열하기 시작하여 바이메탈(7)을 가열하기 시작하게 된다.When the power reaches the motor M to reach a certain torque in order to drive the compressor in the connected state as described above, overcurrent flows through the main winding of the motor, thus connecting between the terminal 3 and the terminal 3 ". -The starter wire 6 also starts to generate heat and starts to heat the bimetal 7.

따라서 바이메탈(7)은 제4도에 도시된 바와같은 상태에서 제5도의 단면도에 도시한 바와같이 점차적으로 외향으로 굽어지면서 가동편(8)의 볼록부(8')를 밖으로 밀게된다. 이에 따라 가동편(8)은 일측이 단자(10)에 의해 구멍(10')이 고정되어 있으므로 타측에 설치된 단자(9)가 터미널(3')으로부터 떨어지게 되므로 전동기와 직열상태의 단자(10)와 단자(9)사이는 전기적으로 OFF상태가 되어 전동기의 주권선에 흐르는 전류를 제어하게 된다.Thus, the bimetal 7 is pushed out of the convex portion 8 'of the movable piece 8 while gradually bending outward as shown in the cross-sectional view of FIG. 5 in a state as shown in FIG. As a result, the movable piece 8 has a hole 10 'fixed at one side by the terminal 10, so that the terminal 9 installed at the other side is separated from the terminal 3'. Between the terminal and the terminal (9) is electrically OFF to control the current flowing in the main winding of the motor.

또 정지형 릴레이를 구성하는 회로기판(12)에 의해 시간과 냉장고에의 온도를 감지하여 주권선의 전류를 제어하게 되는 것이다.In addition, the circuit board 12 constituting the stationary relay senses time and temperature in the refrigerator to control the current of the main winding.

한편 전동기(M)가 일정도르크에 도달하면 전동기의 주권선(R)에는 역기전류가 발생 과전류가 흐르는데 따라 터미널(3)과 터미널(3")사이에 연결된 히-터선(6)이 발열하여 바이메탈(7)을 가열하게 되며, 어느 일정온도에 도달하면 바이메탈(7)은 제4도에 도시된 바와같은 단면설명의 상태에서 제5도의 단면 설명도에 도시한 바와같이 바이메탈(7)은 외향으로 굽어지면서 가동편(8)의 볼록부(8')를 밖으로 밀게 된다. 이에따라 가동편(8)은 일측이 단자(10)에 의해 구멍(10')에 고정되어 있으므로 타측에 설치된 단자(9)가 터미널(9-1)로부터 떨어지게 되므로 터미널(9-1)이 터미널(3')에 연결된 상태에서 개방되어 전동기에 흐르는 전원을 제어하게 되는 것이다.On the other hand, when the motor M reaches a certain dock, a counter-current occurs in the main winding line R of the motor, and as a result of overcurrent, a heater wire 6 connected between the terminal 3 and the terminal 3 "generates heat. The bimetal 7 is heated, and when a certain temperature is reached, the bimetal 7 is turned outward as shown in the cross-sectional explanatory view of FIG. 5 in the state of the cross-sectional view as shown in FIG. Is pushed out of the convex portion 8 'of the movable piece 8. Accordingly, the movable piece 8 is fixed to the hole 10' by the terminal 10 so that the terminal 9 is provided on the other side. Since the terminal 9-1 is separated from the terminal 9-1, the terminal 9-1 is opened while being connected to the terminal 3 'to control the power flowing to the motor.

이와같이 본 고안에 의하면 일정온도로 가동되도록 전류제한기(4)가 설치되고, 콘텐서(C2)와 저항(R1, R3)으로 타이머회로가 구성되어 일정시간후 기동권선에 흐르는 전류를 제어할뿐 아니라 실리콘제어정류소자(SCR)에 다이오드(D1)가 직열연결되어 있음으로서 전원 OFF시 실리콘제어정류소자를 즉시 불통시켜 스위치를 OFF 하는데 따라 즉시 가동되며 진력손실을 방지할 수 있는 실용적인 고안인 것이다.As described above, according to the present invention, a current limiter 4 is installed to operate at a constant temperature, and a timer circuit is composed of the capacitor C 2 and the resistors R 1 and R 3 so that the current flowing in the starting winding after a certain time is obtained. In addition to controlling the diode, the diode D 1 is connected directly to the silicon control rectifier (SCR), so that when the power is turned off, the silicon control rectifier is immediately turned off and immediately operates by turning off the switch. It is
