본 고안은 세탁기의 모터구동회로에 관한 것으로, 특히 세탁기에서 세탁시 정,역회전하고, 탈수시 고속회전하는 세탁모터에 있어서, 상기 세탁및 탈수시 그에 해당하는 토오크로 구동하면서 세탁및 탈수를 할수 있도록 한 세탁기의 모터구동회로에 관한 것이다.The present invention relates to a motor driving circuit of a washing machine, and in particular, in a washing motor that rotates forward and reverse when washing in a washing machine and rotates at high speed when dewatering, the washing and dehydration can be performed while driving with a corresponding torque during washing and dehydration. To a motor drive circuit of a washing machine.
일반적으로 세탁기에는 일련의 세탁행정을 수행하기 위하여 정,역회전 및 고속회전하는 모터구동회로가 구비되어 잇는바, 상기 모터구동회로는 세탁및 헹굼시 정,역회전하고, 탈수시 고속회전하는 세탁모터와, 이 세탁모터를 기동시키는 기동콘덴서가 구비되어 있다.In general, a washing machine is provided with a motor driving circuit for forward, reverse rotation and high speed rotation in order to perform a series of washing strokes. The motor driving circuit rotates forward, reverse when washing and rinsing, and washing at high speed when dewatering. A motor and a starting capacitor for starting this washing motor are provided.
그리고 상기 모터구동회로는 제1도에 도시한 바와 같이, 세탁모터(M)를 기동하는 기동콘덴서(C1)가 하나 접속되어 세탁, 헹굼 및 탈수시 하나의 기동콘덴서(C1)로 세탁모터(M)를 정,역회전 및 고속회전을 하도록 되어있다. 그러므로 상기 세탁모터(M)를 기동하는 기동콘덴서(C1)의 용량을 크게 하면, 세탁및 헹굼시, 기동토오크가 커서 회전력이 강하여 옷감의 손상을 주는 반면에 탈수시 탈수력은 좋아지게 되고, 반대로 상기 기동콘덴서(C1)의 용량을 작게 하면, 기동토오크가 작아 세탁및 헹굼시 옷감에 손상을 막을 수 있지만, 초기 기동력이 약하여 탈수시 약간의 언발란스가 발생하여도 초기 기동을 하지 못하여 원활한 탈수행정을 할수 없게 된다.In addition, as shown in FIG. 1, the motor driving circuit includes one starting capacitor C1 for starting the washing motor M and is connected to one starting capacitor C1 for washing, rinsing, and dehydration. ) Forward, reverse and high speed rotation. Therefore, if the capacity of the starting capacitor (C1) for starting the washing motor (M) is increased, the starting torque is large during washing and rinsing, and the rotational force is strong to damage the cloth, while the dehydration power is improved when dewatering. If the capacity of the starting capacitor (C1) is reduced, the starting torque is small, thereby preventing damage to the cloth during washing and rinsing. You can't.
이와같이 종래의 세탁모터는 하나의 기동콘덴서로 상기 세탁및 헹굼 그리고 탈수행정을 수행할 경우, 어느하나를 만족하면 다른 하나는 만족을 시킬수없는 문제점을 가지고 있었다.Thus, when the conventional washing motor performs the washing, rinsing, and dehydrating administration with one starter capacitor, if one satisfies one, the other has no problem.
따라서 본 고안의 목적은 정,역회전하는 세탁및 헹굼행정과, 고속회전하는 탈수행정시 그 행정에 해당하는 회전토오크로 구동 할수 있도록 기동콘덴서를 각각 구성하여 상기 각각의 행정에 맞는 회전토오크로 구동하도록 함으로써, 만족할 만한 일련의 세탁행정을 수행할 수 있도록 하고자 하는데 있다.Therefore, the object of the present invention is to configure the driving capacitor to be driven by the rotating torque corresponding to the respective strokes, respectively, so as to drive the washing and rinsing strokes of the forward and reverse rotation and the rotating torque corresponding to the stroke during the dewatering stroke of the high speed rotation. By doing so, it is intended to be able to perform a series of satisfactory washing administration.
상기의 목적을 실현하기 위하여 본 고안은 세탁및 헹굼행정과 탈수행정시 기동콘덴서에 의하여 소정의 회전토오크로 정,역회전및 고속회전하는 모터구동회로에 있어서, 상기 모터구동회로에 상기 세탁및 헹굼행정과 탈수행정시 그 해당행정에 따라 그에 해당하는 회전토오크로 선택 구동할수 있는 각기 다른 용량의 기동콘덴서를 구성하여서 된 것을 특징으로 한다.In order to achieve the above object, the present invention is a motor drive circuit for forward, reverse rotation and high speed rotation by a predetermined rotation torque by a starting capacitor during washing and rinsing stroke and dehydration stroke, wherein the washing and rinsing stroke is applied to the motor driving circuit. It is characterized by the configuration of a starting capacitor of different capacity that can be selectively driven by the corresponding rotary torque in the dehydration stroke.
이하 첨부된 도면에 의거 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

속회전시키는 저항(R1-R8), 콘덴서(C2-C5), 트랜지스터(TR1-TR3), 트라이액(TRI-AC1, TRIAC2)로 구성되는 모터구동회로(가)로 구성되는 세탁기에 있어서, 상기 모터구동회로(가)의 세탁모터(M)의 양단간에 탈수전용 기동콘덴서(C1), 기동코일(L1)과 세탁전용 기동콘덴서(C6), 기동코일(L2)을 병렬로 접속하고, 상기 탈수전용 기동콘덴서(C1), 기동코일(L1)과 세탁전용 기동콘덴서(C6), 기동코일(L2)에는 상기 마이콤(나)의 제어신호에 의하여 구동하면서 상기 세탁전용 기동콘덴서(C6)를 절환 선택하는 저항(R9)(R10), 트랜지스(TR4), 릴레이(RY1)로 구성되는 릴레이구동부(다)로 구성하여서 된 것이다.In the washing machine comprising a motor driving circuit (A) consisting of a resistor (R1-R8), a capacitor (C2-C5), a transistor (TR1-TR3), a triac (TRI-AC1, TRIAC2) to rotate at high speed. The dehydration starting capacitor C1, the starting coil L1, the washing starting capacitor C6 and the starting coil L2 are connected in parallel between both ends of the washing motor M of the motor driving circuit A. The washing starter capacitor C6 is selected and switched to the dedicated starting capacitor C1, the starting coil L1, the washing starting capacitor C6, and the starting coil L2 while being driven by the control signal of the microcomputer (b). The relay drive unit (C) constituted by resistors R9, R10, transistor TR4, and relay RY1 is used.
상기와 같이 구성되는 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is configured as described above are as follows.
먼저 세탁을 하기 위하여 세탁기에 전원을 인가하고, 이어서 세탁하고자하는 세탁물을 세탁조(도시되지않음)에 넣고, 운전신호입력부(도시되지않음)를 통해서 일련의 세탁행정에 대한 운전신호를 마이콤(나)에 입력시키게 되면 상기 마이콤(나)에서는 입력되는 운전신호에 대하여 기설정된 소정의 프로그램에 의하여 제어하고 제어된 신호를 출력하여 상기 세탁량에 따른 급수하면서 모터구동회로(가)를 제어하여 일련의 세탁및 헹굼행정을 진행하게 되는바, 즉 상기 세탁행정이 시작되게 되면 상기 마이콤(나)에서는 릴레이구동부(다)에 제어신호를 출력하여 릴레이(RY1)를 구동시킴으로써, 상기 릴레이(RY1)와 연동하는 릴레이단자가 세탁전용 콘덴서(C6)를 선택하여 주게 되고, 이어서 상기 마이콤(나)에서는 모터구동회로(가)의 트라이액(TRIAC1, TRIAC2)을 교번 구동시켜 상기 세탁전용 기동콘덴서(C6)의 기동용량에 의한 소정의 회전토오크로 세탁모터(M)를 정,역회전시키면서 일련의 세탁행정및 헹굼행정을 수행하게 된다.First, turn on the washing machine to wash the laundry, and then put the laundry to be washed in the washing tank (not shown), and send the driving signal for a series of washing administration through the driving signal input unit (not shown). When the input to the microcomputer (b) is controlled by a predetermined predetermined program for the input operation signal and outputs a controlled signal to control the motor driving circuit (a) while supplying the water according to the washing amount of a series of washing and A rinsing stroke is performed. That is, when the washing stroke starts, the microcomputer (b) outputs a control signal to the relay driving unit (c) to drive the relay RY1, thereby relaying the relay RY1. The terminal selects the condenser for washing (C6), and then, in the microcomputer (B), the triacs (TRIAC1, TRIAC2) of the motor driving circuit (A) By alternately driving the washing motor (M) with a predetermined rotational torque by the starting capacity of the washing dedicated starting capacitor (C6) to perform a series of washing and rinsing stroke while rotating the washing motor (M).
한편 상기 세탁행정및 헹굼행정이 완료되게 되면 상기 마이콤(나)에서는 기설정된 소정의 프로그램에 의하여 탈수행정을 진행하게 되는데, 이때 상기 마이콤(나)에서는 릴레이구동부(다)에 제어신호를 차단하게 되고, 따라서 릴레이(RY1)는 구동을 정지하게 되므로 이와 연동하는 릴레이단자는 상기 세탁전용 기동콘덴서(C6)에서 탈수전용 기동콘덴서(C1)로 절환되게 된다.Meanwhile, when the washing stroke and the rinsing stroke are completed, the microcomputer (b) proceeds with dehydration stroke by a predetermined program. In this case, the microcomputer (b) blocks the control signal to the relay driver (c). Therefore, since the relay RY1 stops driving, the relay terminal interlocked with the relay RY1 is switched from the washing dedicated starting capacitor C6 to the dehydrating starting capacitor C1.
이와같이 상기 세탁모터(M)의 기동콘덴서를 탈수전용 기동콘덴서(C1)로 절환시켜 놓은 상태에서 상기 마이콤(나)에서는 모터구동회로(가)가 제어하되 모터구동회로(가)의 트라이액(TRIAC1)만을 구동하여 상기 탈수전용 기동콘덴서(C1)의 기동용량에 의한 소정의 회전 토오크로 고속회전시키면서 탈수행정을 수행시키게 됨으로써, 각행정에 따른 그에 해당하는 회전토오크로 일련의 세탁행정을 원활하면서도 효율적으로 수행할수 있게되는 것이다.In this way, the motor driving circuit (A) is controlled in the microcomputer (B) while the start capacitor of the washing motor (M) is switched to the dehydration starting capacitor (C1), but the triac (TRIAC1) of the motor driving circuit (A) is controlled. ) To perform the dehydration stroke while rotating at a high speed with a predetermined rotational torque based on the starting capacity of the dehydration starter capacitor C1, thereby smoothly and efficiently performing a series of washing strokes with the corresponding rotation torque according to each stroke. It can be done with.
이상에서 설명한 바와같이 본 고안은 일련의 세탁행정중 세탁및 헹굼행정과 탈수행정시 그에 해당하는 행정에 따른 회전토오크에 맞는 기동콘덴서를 절환선택하여 일련의 세탁행정을 수행하도록 함으로써, 세탁및 헹굼시에는 강한 회전토오크에 의한 옷감의 손상을 방지할수 있고, 탈수시에는 약한 회전토오크에 의하여 기동이 이루어지지 않게 되는 문제점을 해소할수 있는 효과를 제공하게 되는 것이다.As described above, the present invention selects a switching condenser according to the rotational torque according to the corresponding stroke during the washing and rinsing stroke and the dehydrating stroke during the series of washing strokes to perform a series of washing strokes. It is possible to prevent the damage of the cloth due to the strong rotational torque, and to provide an effect that can solve the problem that the start is not made by the weak rotational torque when dewatering.
