Referring to the effect of the present invention as follows.

정전압회로부(1) 및 정전시 전원공급회로부(2)로부터 DC전원을 공급받아 주제어부(3)가 작동하며 주제어부(3)의 작동은 LSI에 4개의 입력(I1), (I2), (I3), (I4)중 메모리용 단자(I1), (I2), (I3)는 스윗치(S1∼S7)로서 세탁의 7가지 양식은 선택하게끔 LSI에 메모리입력을 제공하는 단자이고, 나머지 입력단자(I4)는 신호선택IC(MSI)로부터 세탁기의 작동상태를 감지한 감지신호 입력으로 사용되는 것인데, 스윗치(S8∼S15)는 "1" 또는 "0"의 두상태로 되어 있어 외부에서 세탁기의 작동감지를 조작 결정하여 LSI의 감지출력단자(C1), (C2), (C3)로부터 감지지시를 받아서 감지신호만을 선택하도록 한 것으로, LSI는 항시 4개의 입력신호(I1), (I2), (I3), (I4)만을 선택할 수 있고, 데이터(data) 선택용 IC는 멀티 플렉서(Multi Plexer)로서 LSI로부터의 제어신호를 받아서 8개의 입력중 1개의 입력만을 선택하여 다시 LSI의 감지입력으로 사용한다.The main control unit 3 operates by receiving DC power from the constant voltage circuit unit 1 and the power supply circuit unit 2 in case of power failure, and the operation of the main control unit 3 is performed by four inputs I 1 and I 2 . , (I 3), (I 4) for the memory of the terminal (I 1), (I 2 ), (I 3) is a switch (S 1 ~S 7) as a 7 forms hagekkeum memory is input to the LSI selection of washing The other input terminal I 4 is used as a detection signal input that detects the operating state of the washing machine from the signal selection IC (MSI), and the switches S 8 to S 15 are “1” or “. It is in two states of 0 ", and the operation detection of the washing machine is externally determined to receive the detection instruction from the detection output terminals (C 1 ), (C 2 ) and (C 3 ) of the LSI to select only the detection signal. The LSI can only select four input signals (I 1 ), (I 2 ), (I 3 ), and (I 4 ) at any time, and the data selection IC is a multiplexer from the LSI. Receive control signal Selecting only one of the inputs of the eight inputs to be re-used as the sense input of the LSI.

세탁기의 기능은 3개의 메모리 입력과 8개의 쎈서중 하나의 선택입력에 따라 이 입력을 받아 세탁기의 기능을 제어하는 LSI에 내장된 메모리에 기억시킨 프로그램에 의하여 작동되며, 표시램프(4)는 세탁기를 사용시 그 과정을 표시해 주는 것으로서, LSI의 콘트롤 신호와 출력신호에 의해 각 램프를 선택하도록 되어 있으며, 세탁중에는 램프(LED1)가 동작되고, 헹굼중에는 램프(LED2)가 동작하며, 탈수중에는 램프(LED3)가 동작하도록 함으로서 세탁과정을 일목요연하게 알 수 있도록 작동하고, 또한 세탁중에 이상이 발생할 경우 이상을 표시하는 목적으로도 작동이 가능하며, 동작지시부(5)는 LSI의 출력신호를 받아 세탁기에 직접 구동신호를 보내는 것으로서, 각각 앰프(A1∼A6)에서 모우터, 급수, 밸브용 솔레노이드, 배수밸브용 솔레노이드, 리레이, 부저등을 동작하도록 신호를 증폭하여 세탁기의 각 부분에 전원을 공급하며, 이와같은 상기동작의 한 실예로서 세탁물이 면질물일 경우에는 급수, 모우터, 헹굼, 탈수의 순으로 이에 해당하는 스윗치(S1∼S7)를 순서대로 눌러 컴퓨터에 메모리시키고, 나이론 및 모직물일 때에는 세탁물의 특성에 따라 급수, 모우터, 헹굼의 작동만을 스윗치(S1∼S7)를 순서대로 눌러 컴퓨터에 메모리시키므로서 면직물을 세탁하기 위하여 전자의 순서대로 LSI에 프로그램했다면, LSI에서 동작지시부(5)로 첫번째는 신호를 앰프(A4)로 보내어 급수밸브를 일정시간 열어주고, 두번째는 신호를 앰프(A1)로 보내어 모우터를 구동시키다가 세번째는 신호를 앰프(A3)로 보내어 배수밸브를 열어주며, 네번째는 신호를 앰프(A2)에 보내어 탈수지시를 하는 것으로 작동되는 것이다.The function of the washing machine is operated by a program stored in the memory built into the LSI which receives this input according to a selection input of three memory inputs and one of eight processors and controls the washing machine's function. It displays the process when using, and each lamp is selected by control signal and output signal of LSI, lamp (LED 1 ) is operated during washing, lamp (LED 2 ) is operated during rinsing, and during dehydration By operating the lamp (LED 3 ) to be able to know the washing process at a glance, and also to display the abnormality when the abnormality occurs during washing, it is also possible to operate, the operation instruction unit (5) outputs the output signal of the LSI take as sending a signal to direct drive washing machine, each amplifier (a 1 ~A 6) Motor, water supply, solenoids, solenoid, relay for a drain valve in the valve, Amplifies the signal to operate the jeodeung if the if the laundry as a silye of the operation and to power, this in each part of the washing machine jilmul has switch equivalent to the water supply, Motor, rinsing, the order of dehydration (S 1 ~ S 7 ) in order to memory in the computer, and in case of nylon and woolen fabric, press the switches (S 1 ~ S 7 ) in order to store in the computer according to the characteristics of the laundry only If the program in the LSI as the electronic order to wash the cotton, to an operating instruction section 5, the LSI first give sent by opening the inlet valve a predetermined time the signal to the amplifier (a 4), the second amplifier signal (a 1) is sent to the drive train Motor a third one gives to open the drain valve by sending a signal to the amplifier (a 3), fourth is actuated by a dehydration indicating sending a signal to the amplifier (a 2) .

이와같은 방법으로 메모리 스윗치(S1∼S7)로서 미리 적당한 주기를 프로그램한 것이 끝나면 앰프(A6)에 신호를 보내어 부저를 울리면 세탁이 끝났음을 알려주는 일련의 세탁과정을 동작지시부(5)에 지시한다. 이러한 동작이 진행되는 중에 LSI에서는 표시부(4)로 지시하여 세탁이 행하여지고 있는 과정을 표시하고, 이러한 작동이 진행중 AC전원이 차단되면 LSI에서 이를 감지하여 동작지시부(5)의 앰프(A5)에 신호를 보내어 리레이를 구동하여 이와 연동되는 리레이(Ry1)를 ON시키므로 정전이 되어도 전원공급부(2)의 건전지(B1)에서 리레이(Ry1) 및 다이오드(D6)를 통해 LSI에 전원을 공급하므로 작동진행중이던 프로그램을 계속 기억시켜 주어 AC전원이 들어왔을 경우 남은 프로그램을 계속 작동하여 정상적인 세탁과정이 끝난 경우에는 LSI의 프로그램에 의해 건전지(B1)에 연동으로 접속된 리레이(Ry1)의 접점을 차단시킴으로 세탁기를 사용하지 않을 때에는 건전지(B1)가 전혀 소모되지 않도록 작동하는 것이다.In this way, when the memory switches S 1 to S 7 have been programmed with suitable cycles in advance, a signal is sent to the amplifier A 6 so that a buzzer sounds to indicate that the washing is finished. Instruct on. While the operation is in progress, the LSI instructs the display unit 4 to display a process in which washing is being performed, and when the AC power is cut off during this operation, the LSI detects this and the amplifier A 5 of the operation instruction unit 5 operates. By sending a signal to drive the relay to turn on the relay (Ry 1 ) that is linked to this, even in the event of a power outage from the battery (B 1 ) of the power supply (2) through the relay (R 1 ) and diode (D 6 ) As the power is supplied to the LSI, it keeps memorizing the program in progress. When AC power is turned on, the remaining program continues to operate. When the normal washing process is completed, the LSI program is connected to the battery (B 1 ). By blocking the contacts of the Ray (Ry 1 ), when the washing machine is not in use, the battery (B 1 ) is operated so as not to be consumed at all.

이와같은 본 고안은 정전시에도 사용중인 상태를 기억하여 다음 작동이 가능하게 하며 프로그램에 의해 세탁중 고장을 자동으로 탐지수정하며 이상한 동작을 감지할 수도 있고 주제어부에서 세탁기의 작동주기를 적절히 프로그램하므로 완전자동으로 세탁이 가능하며 세탁이 끝난 경우 인입부에서 전원을 차단시킴으로 안전성이 있으며 세탁기능이 다양하고 완전자동인 특징을 지닌 것이다.The present invention remembers the state of use even in the event of a power outage, and enables the next operation. The program automatically detects and corrects a malfunction during washing, and can detect strange movements. Fully automatic washing is possible. When washing is finished, it is safe by cutting off the power at the inlet part.
