본 발명은 전자동 세탁기의 간헐탈수장치 및 방법에 관한 것으로, 탈수시 세탁물의 양에 따라 탈수조 회전속도를 제어하고 간헐 탈수 횟수도 달리하여 세탁물의 양에 따라 간헐탈수를 진행하는 간헐 탈수장치 및 방법에 관한 것이다.The present invention relates to an intermittent dewatering device and method of a full-automatic washing machine, and the intermittent dewatering device and method for controlling the rotation speed of the dehydration tank according to the amount of laundry during dehydration and the intermittent dehydration according to the amount of laundry by varying the number of intermittent dehydration It is about.

제1도는 종래 기술의 간헐 탈수를 실행하기 위한 세탁기의 탈수 모터 구동회로도로써 그에 대한 설명은 다음과 같다.1 is a dehydration motor driving circuit diagram of a washing machine for performing intermittent dehydration of the prior art, the description thereof is as follows.

먼저, 마이콤(1)에서 하이(high)신호를 출력하면 트랜지스터(2)가 온되어 트라이액(3)의 게이트단에 트리거 신호가 인가되고, 트라이액(3)이 턴 온(turn on)되어 탈수모터(4)에 220V의 전원(5)이 인가됨으로써 탈수 모터(4)의 구동에 의해 탈수를 진행한다.First, when the microcomputer 1 outputs a high signal, the transistor 2 is turned on to apply a trigger signal to the gate terminal of the triac 3, and the triac 3 is turned on. The 220V power supply 5 is applied to the dehydration motor 4 so that the dehydration is carried out by driving the dewatering motor 4.

또한 상기 마이콤(1)에서 로우(low)신호를 출력하면 트랜지스터(2)가 오프(off)되어 트라이액(3)이 턴오프되어 탈수모터(4)의 구동이 멈춰지고 탈수는 중지된다.In addition, when the microcomputer 1 outputs a low signal, the transistor 2 is turned off, the triac 3 is turned off, the driving of the dehydration motor 4 is stopped, and the dehydration is stopped.

상기에서 알수있듯이 탈수모터(4)는 마이콤(1)의 출력신호에 의해 온, 오프되는 데 제2도에 나타난 바와 같이 마이콤(1)에서 일정 시간 동안 하이, 로우신호를 (T1, T2)반복적으로 출력함으로써 상기 탈수모터(4)는 제3도와 같이 온, 오프되어 동작한다.As can be seen from the above, the dehydration motor 4 is turned on and off by the output signal of the microcomputer 1, and as shown in FIG. 2, the high and low signals are output for a predetermined time in the microcomputer 1 (T 1 , T 2). By repeatedly outputting, the dehydration motor 4 is turned on and off as shown in FIG.

이때 상기 마이콤(1)에 출력하는 하이 및 로우신호, 즉 간헐 탈수 온, 오프시간은 세탁물의 양에 관계없이 고정되어 있고 간헐탈수 회수(N)도 6회 내지 12회 정도로 선택 사용할 수 있도록 고정되어있다.At this time, the high and low signals output to the microcomputer 1, that is, intermittent dehydration on and off times are fixed regardless of the amount of laundry, and the intermittent dehydration recovery (N) is also fixed to be selectively used about 6 to 12 times. have.

제1도의 미설명 부호인 R1내지 R4는 저항이고, C1, C2는 콘덴서를 나타낸다.R 1 to R 4, which are not described in FIG. 1 , are resistors, and C 1 and C 2 represent capacitors.

제4도는 종래 기술의 간헐 탈수방법을 나타낸 전체 흐름도로써 그에 대한 설명은 다음과 같다.4 is an overall flowchart showing an intermittent dewatering method of the prior art, the description thereof is as follows.

사용자가 탈수를 선택하여 탈수를 시작하면(100) 현재 실행되는 탈수가 본탈수인지 간헐탈수인지를 조사하여(101) 현재 실행되는 탈수가 간헐탈수이면 간헐 탈수 실행횟수를 체크한다(102).When the user selects dehydration to start dehydration (100), it is checked whether dehydration that is currently executed is main dehydration or intermittent dehydration (101). If the dehydration that is currently executed is intermittent dehydration, the intermittent dehydration execution frequency is checked (102).

간헐 탈수 실행횟수가 기설정된 회수(N)에 도달하지 않은 상태에서 탈수모터(4)가 오프되었으면(103) 기설정된 시간(T1)만큼 탈수모터(4)를 구동시키고(104) 탈수모터(4)가 온되었으면(103) 탈수모터(4)를 기설정된 시간만큼 오프시켜(105) 탈수모터(4)의 구동이 멈추도록 한다.If the dehydration motor 4 is turned off while the intermittent dehydration execution frequency does not reach the predetermined number N (103), the dewatering motor 4 is driven for a predetermined time T 1 (104) and the dehydration motor ( When 4) is turned on (103), the dewatering motor 4 is turned off for a predetermined time (105) to stop the driving of the dewatering motor 4.

상기 과정후 탈수모터(4)의 온, 오프 시간을 주기로 간헐 탈수 횟수를 카운트하여(106) 다시 간헐 탈수 횟수가 기설정된 횟수(N)만큼 실행했는지를 체크함으로써(102) 기설정된 간헐 탈수 횟수(N)에 도달할때까지 탈수 모터(4)를 온, 오프시켜 간헐 탈수를 실행하여 상기 제3도에 나타난 바와 같이 탈수모터(4)의 속도를 점차 상승시킨다.After the process, the intermittent dehydration number is counted at a cycle of turning on and off the dehydration motor 4 (106) to check whether the intermittent dehydration number has been executed by a predetermined number (N) (102). Intermittent dehydration is performed by turning on and off the dehydration motor 4 until N) is reached to gradually increase the speed of the dehydration motor 4 as shown in FIG.

간헐 탈수가 기설정된 횟수(N)만큼 실행하고 나면(102) 간헐 탈수를 끝내고(107) 기설정된 본탈수 실행시간만큼 탈수록 진행한다(108).After the intermittent dehydration is executed for a predetermined number of times (N) (102), the intermittent dehydration is finished (107) and proceeds as much as the predetermined main dehydration execution time (108).

그러나, 종래 기술의 간헐 탈수방법은 상기에서 알수있듯이 간헐 탈수 횟수와 탈수 진행시간들이 기설정되어 있어 세탁조내의 세탁물의 양에 관계없이 간헐 탈수를 실행하기 때문에 간헐 탈수시 소음이 높고, 세탁물이 일방향으로 치우침으로 인해 전동 특성이 나빠지게 되면 세탁물의 불균형에 의해 외부장치와 내부 회전통과의 부딪침이 발생하고 모터의 부하 구동 시스템에 무리가 가해지는 문제점이 있었다.However, the intermittent dewatering method of the prior art has a high noise when intermittent dehydration because the number of intermittent dehydration and the dehydration progress time are set in advance so that intermittent dehydration is performed regardless of the amount of laundry in the washing tank, and the laundry is oriented in one direction. When the electric characteristics are deteriorated due to the bias, a collision between the external device and the internal rotary tube occurs due to the imbalance of laundry, and there is a problem that the load driving system of the motor is applied to the load.

본 발명은 상기 문제점을 해결하기 위하여 안출된 것으로써, 탈수시 세탁물의 양에 따라 탈수조 회전 속도를 제어하고 간헐 탈수 횟수도 달리하여 간헐 탈수를 실행함으로써 진동발산과 소음을 줄이고 구동장치의 부하를 줄일수있는 전자동 세탁기의 간헐 탈수장치 및 방법을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, by controlling the spin speed of the dehydration tank according to the amount of laundry during dehydration, and by intermittent dehydration by varying the number of intermittent dehydration to reduce the vibration divergence and noise and to reduce the load of the driving device It is an object of the present invention to provide an intermittent dewatering device and method of a fully automatic washing machine.

이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

제5도는 본 발명의 실시예를 나타낸 간헐 탈수장치의 전체 구성도로써, 탈수조(10)를 구동하기 위한 탈수 모터(4)의 일측 회전축에 N개의 극성을 갖는 마그네트(11)를 부착하고 마그네트(11)일측에 마그네트(11)의 자속변화를 감지하도록 탈수모터(4)에 회전 속도 감지부(12)를 부착시켜 모터속도에 상응한 펄스신호를 출력하도록 하여 상기 마이콤(1)에 인가하고 상기 탈수모터(4)의 타측 회전측에 모터풀리(13)를 설치하고 탈수조(10)를 회전시킬수 있도록 클러치(14)를 설치하고 클러치(14)의 회전축에 클러치 풀리(15)를 설치하여 모터풀리(13)와 클러치풀리(15)를 V벨트(16)로 연결시켜 탈수모터(4)의 회전력이 탈수조(10)에 전달되도록 한다.5 is an overall configuration diagram of an intermittent dewatering device showing an embodiment of the present invention, in which a magnet 11 having N polarities is attached to one rotation shaft of the dewatering motor 4 for driving the dewatering tank 10 and the magnet (11) attaching the rotational speed detection unit 12 to the dehydration motor 4 to detect the magnetic flux change of the magnet 11 on one side to output a pulse signal corresponding to the motor speed and apply it to the microcomputer 1 By installing the motor pulley 13 on the other side rotation side of the dehydration motor (4) and the clutch 14 so as to rotate the dehydration tank (10) and by installing the clutch pulley (15) on the rotating shaft of the clutch 14 The motor pulley 13 and the clutch pulley 15 are connected by the V belt 16 so that the rotational force of the dehydration motor 4 is transmitted to the dehydration tank 10.

여기서 상기 마그네트(11)와 회전 속도 감지부(12)를 제6도 및 제7도를 참조하여 설명하면 N극과 S극을 반복적으로 형성한 원형의 6극(N극) 마그네트(11) 일측에 홀 IC(20)를 설치하고 홀 IC(20)의 양단에 출력되는 전압치를 비교할 수 있도록 비교기(21)를 연결하고 비교기(21)의 출력에 따라서 구형파 신호를 발생할 수 있도록 트랜지스터(22)를 연결한후 신호전달회로부(23)에 의해 상기 마이콤(1)에 구형파 신호가 입력되도록 구성한다.Here, the magnet 11 and the rotational speed sensing unit 12 will be described with reference to FIGS. 6 and 7. One side of a circular 6-pole (N-pole) magnet 11 repeatedly formed with the N-pole and the S-pole. The transistor 22 is connected to the comparator 21 so that the hall IC 20 can be installed at the same time, and the voltage values outputted at both ends of the hall IC 20 can be compared, and the square wave signal can be generated according to the output of the comparator 21. After connecting, the square wave signal is inputted to the microcomputer 1 by the signal transfer circuit 23.

상기와 같이 구성된 회전속도 감지부(12)는 6극 마그네트(11)가 한바퀴 회전시 극성이 6번 바뀌게 되므로 이에 따른 자속변화에 의해 홀 IC(20)의 양단(A, B)에 전압차가 발생된다.In the rotation speed detecting unit 12 configured as described above, since the polarity is changed six times when the six-pole magnet 11 rotates once, a voltage difference is generated at both ends A and B of the hall IC 20 due to the change of magnetic flux. do.

발생된 전압차는 비교기(21)의 입력단에 인가되므로 비교기(21)가 전압차에 따라 로우/하이신호를 출력하게 되고 비교기(21)의 출력에 따라 트랜지스터(22)가 온/오프되어 탈수모터(4)의 회전속도에 따른 구형파신호를 출력하게 된다.Since the generated voltage difference is applied to the input terminal of the comparator 21, the comparator 21 outputs a low / high signal according to the voltage difference, and the transistor 22 is turned on / off according to the output of the comparator 21, thereby dehydrating the motor ( Square wave signal is outputted according to the rotation speed of 4).

또한, 이와 같이 구형파 신호를 출력하는 회전속도감지부(12)와 마이콤(1)의 연결관계는 회전속도 감지부(12)를 마이콤(1)에 연결할 수 있도록 콘넥터(3핀, ①②③)(24)를 이용하고 커패시터(C11~C12), 저항(R11~R14), 다이오드(D11), 트랜지수터(Q1)등으로 이루어진 신호전달회로부(23)를 통해 마이콤(1)에 입력되도록 한다.In addition, the connection between the rotation speed detection unit 12 and the microcomputer 1 that outputs the square wave signal in this way is a connector (3 pins, ① ② ③) (24) to connect the rotation speed detection unit 12 to the microcomputer 1 The microcomputer 1 is connected to the microcomputer 1 through a signal transmission circuit unit 23 formed of a capacitor C 11 to C 12 , a resistor R 11 to R 14 , a diode D 11 , a transistor sour Q 1 , and the like. To be entered.

즉, 회전속도감지부(12)에서 출력된 파형은 트랜지스터(Q11)의 베이스단에 인가되어 트랜지스터(Q11)는 온, 오프 동작을 반복하므로 베이스단에 인가된 파형은 반전되어 콜렉터단에 유입되고 반전된 신호는 마이콤(1)에 인가되므로 마이콤(1)에서 탈수모터(4)의 회전속도를 인식할 수 있게된다.That is, the rotational sense of speed of a waveform output from the branch 12 is applied to the base of the transistor (Q 11) transistor (Q 11), so repeatedly turned on and off operation is the inversion is applied to the base terminal waveform flowing into the collector stage And the inverted signal is applied to the microcomputer (1) it is possible to recognize the rotational speed of the dehydration motor (4) in the microcomputer (1).

탈수모터(4)의 속도가 빠르면 마이콤(1)에 인가되는 펄수의 주파수가 높아지고 회전 속도가 느리면 주파수가 낮아진다.If the speed of the dewatering motor 4 is high, the frequency of the number of pearls applied to the microcomputer 1 is high, and if the rotation speed is slow, the frequency is low.

제8도는 본 발명의 간헐 탈수방법을 나타내는 전체 흐름도로써 그에 대한 설명은 다음과 같다.8 is an overall flow chart showing the intermittent dewatering method of the present invention, the description thereof is as follows.

사용자가 탈수를 시작하면(200) 현재 실행되는 탈수가 간헐탈수인지 본탈수인지를 체크하고(201) 간헐탈수이면 탈수모터(4)를 구동한후(202), 탈수모터(4)의 회전속도가 최대(Rmx)에 도달할때까지의 시간(Tx1>TX2>Tx3)…Txn을 체크한다(203).When the user starts dehydration (200), it is checked whether dehydration that is currently executed is intermittent dehydration or main dehydration (201). If intermittent dehydration is performed, the dehydration motor (4) is driven (202), and the rotational speed of the dehydration motor (4) Until Tx reaches maximum (Rmx) (T x1 > T X2 > T x3 ). Check T xn (203).

지정된 탈수모터(4)의 최대 속도에 도달하는 시간이 매우 짧으면(제9a도, Txn) 세탁조내의 부하가 매우 적은것으로 판단하고(204) 매우 길면(제9b도, Tx1) 세탁조내에 부하가 매우 많은 것으로 판단한다(204).If the time to reach the maximum speed of the designated dewatering motor 4 is very short (Fig. 9a, Txn), it is determined that the load in the washing tank is very small (204). If the load is very long (Fig. 9b, T x1 ), the load is very high. It is judged as much (204).

이때 마이콤(1) 내부의 롬에는 포량에 따른 탈수 모터(4)의 턴온, 턴오프시간과 간헐 탈수횟수(N1>N2>N3…>Nn)가 저장되어 있어 상기 204 과정에서 검출한 포량으로 탈수 모터(4)의 턴온, 턴오프시간과 간헐 탈수 횟수를 결정한다(205).At this time, the ROM inside the microcomputer 1 stores the turn-on, turn-off time and the number of intermittent spins (N 1 > N 2 > N 3 ...> Nn) of the spin-drying motor 4 according to the amount of discharge. The amount of turn-on, turn-off time and the number of intermittent spins of the spin-drying motor 4 are determined by the amount of discharge (205).

즉, 포량이 매우 적은 것으로 판단되면(204), 탈수모터(4)의 턴온시간을 늘리고 턴오프시간을 줄여 탈수모터(4)의 회전속도를 급격히 상승시키고(제9a도) 간헐 탈수 횟수도 가장 적게(Nn)하여 간헐 탈수를 실행하고(206), 포량이 매우 많은 것으로 판단되며(204), 탈수모터(4)의 턴온시간을 줄이고 턴오프시간을 늘려 탈수모터(4)의 회전속도를 완만히 상승시키고(제9b도), 간헌 탈수 횟수도 가장 많게하여(N1) 간헐 탈수를 실행한다(206).That is, if it is determined that the amount of discharge is very small (204), the turn-on time of the dewatering motor 4 is increased and the turn-off time is decreased to rapidly increase the rotational speed of the dewatering motor 4 (Fig. 9a). It is determined that the intermittent dehydration is carried out with a small amount (Nn) (206), and the amount of water is judged to be very large (204). rises and executes (operation also 9b) by dehydration ganheon lot number also the (N 1) intermittent dehydration 206. the

이때 상기 마이콤(1) 내부의 롬에는 탈수모터(4)의 최대 턴온, 턴오프시간(Tx0, Ty0)을 지정하여 모터(4)의 회전속도가 너무 급히 상승하지 않도록 한다.At this time, the maximum turn-on, turn-off time (T x0 , T y0 ) of the dehydration motor (4) is specified in the ROM inside the microcomputer (1) so that the rotational speed of the motor (4) does not rise too rapidly.

상기 과정후 간헐 탈수 횟수를 카운트하여(207) 상기 205 과정에서 결정한 간헐 탈수 횟수에 도달하면(208) 본 탈수를 실행한다(209).After the process, the number of intermittent dehydration is counted (207). When the number of intermittent dehydration determined in step 205 is reached (208), the dehydration is performed (209).

상기한 바와 같이 본 발명은 세탁조내의 포량에 따라 적절한 속도상승과 간헐 탈수 횟수 제어로 진동 특성을 개선하고 소음을 줄일 수 있으며 구동장치의 로드를 최소화 할 수 있는 효과가 있다.As described above, the present invention has an effect of improving the vibration characteristics and reducing the noise and minimizing the load of the driving device by controlling the appropriate speed increase and the intermittent dehydration frequency according to the quantity of the washing tank.
