본 발명은 세탁기에 관한 것으로, 특히 세탁기의 이상 과부하 감지 및 제어장치를 제공하는데 있다.The present invention relates to a washing machine, and more particularly, to provide an abnormal overload detection and control device for a washing machine.

이하, 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings as follows.

도 1은 종래 기술에 따른 세탁기의 구성을 나타낸 구성도이고, 도 2는 종래 기술에 따른 세탁기의 제어회로를 나타낸 회로도이다.1 is a block diagram showing the configuration of a washing machine according to the prior art, Figure 2 is a circuit diagram showing a control circuit of the washing machine according to the prior art.

도 1에 나타낸 바와 같이, 세탁기의 형상 유지 및 내부보호를 위한 케이스(1)와, 상기 케이스(1) 상면에 부착되어 있는 도어감지스위치(2)와, 상기 케이스(1) 내부에 설치되어 세탁수를 담는 외조(3)와, 상기 외조(3) 내부에 설치되어 세탁물을 세탁하는 내조(4)와, 상기 내조(4)에서 세탁이 이루어지도록 회전력을 발생하는 모터(5)와, 세탁회전판(6)과, 속도변화장치(7)로 구성되어 있다.As shown in FIG. 1, a case 1 for maintaining the shape and internal protection of the washing machine, a door detection switch 2 attached to an upper surface of the case 1, and installed inside the case 1 are washed. An outer tub 3 containing water, an inner tub 4 installed inside the outer tub 3 to wash laundry, a motor 5 generating a rotational force to be washed in the inner tub 4, and a washing rotating plate (6) and the speed change device (7).

이의 동작을 살펴보면, 세탁시 상기 모터(5)가 회전을 하면 이동력은 세탁기의 속도변화장치(7)를 통하여 세탁회전판(6)을 돌리게 되고, 탈수를 할 때도 역시 모터(5)가 회전을 하여 이동력은 세탁기 속도변화장치(7)를 통하여 세탁기 내조(4)가 회전하게 되므로 탈수 기능이 수행된다.Looking at the operation thereof, when the motor (5) rotates during washing, the moving force is rotated by the washing rotary plate (6) through the speed change device (7) of the washing machine, the motor 5 also rotates when dehydration Since the moving force is the washing machine inner tank 4 is rotated through the washing machine speed change device (7), the dehydration function is performed.

종래 세탁기 이상동작 감지장치는 탈수중 세탁물(13)이 세탁기 내조(4)에 한쪽 방향으로 치우치게 되면 세탁기 외조(3)가 흔들리게 되고, 상기 외조(3)가 흔들리면 세탁기 케이스(1) 상면에 부착되어 있는 도어감지스위치(2)에 부딪혀 도어감지스위치(2)가 오프상태가 된다.Conventional washing machine abnormal motion detection device is the washing machine 13 during the dehydration is inclined in one direction to the washing machine inner tank 4, the washing machine outer tank (3) is shaken, when the outer tank (3) is shaken attached to the upper surface of the washing machine case (1) The door detection switch 2 is turned off when the door detection switch 2 is hit.

상기 이상동작 감지장치는 도 2에 도시된 바와 같이, 도어의 열림을 감지하는 도어감지스위치(2)와, 상기 도어감지스위치(2)의 감지신호를 입력받아 모터(5) 를 제어하는 마이콤(12)과, 상기 마이콤(12)의 제어신호를 입력받아 모터(5)를 구동하는 모터구동부(9)로 구성된다.The abnormal motion detection device, as shown in Figure 2, the door detection switch (2) for detecting the opening of the door, the microcomputer to control the motor (5) by receiving the detection signal of the door detection switch (2) ( 12) and a motor driver 9 for receiving the control signal of the microcomputer 12 and driving the motor 5.

상기 도어감지스위치(2)는 탈수 동작시 항상 온 상태가 되므로 마이콤에 0V의 전원이 인가된다.Since the door detection switch 2 is always in the ON state during the dehydration operation, a power of 0 V is applied to the microcomputer.

그러나, 세탁기의 내조(4)에 세탁물(13)이 한쪽 방향으로 치우쳐 외조(3)가 흔들리면 도어감지스위치(2)에 부딪혀 도어감지스위치(2)는 오프상태로 된다.However, when the laundry 13 is biased in one direction to the inner tank 4 of the washing machine and the outer tank 3 is shaken, the door sensing switch 2 is hit and the door sensing switch 2 is turned off.

따라서, 마이콤(12)에 5V의 전원이 인가되어 마이콤의 단자(O3)에서 모터(5) 동작신호가 출력되지 않으므로 모터(5)가 정지되고, 내조(4)의 회전도 멈추게 된다.Therefore, since 5V power is applied to the microcomputer 12 and the motor 5 operation signal is not output from the terminal O3 of the microcomputer, the motor 5 is stopped and the rotation of the inner tank 4 is also stopped.

종래 기술에 따른 세탁기는 세탁중 이상 과부하를 감지하는 장치가 없으므로 사용자가 세탁물을 추가로 많이 넣을 경우 이를 감지하지 못하므로 안전사고 및 고장발생을 일으키는 문제점이 있다.Since the washing machine according to the prior art does not have a device for detecting an abnormal overload during washing, there is a problem of causing a safety accident and a failure since the user does not detect this when the user adds a lot of laundry.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 세탁기 사용중 이상 과부하를 감지하여 세탁기의 동작을 제어함으로써 안전사고 방지 및 고장발생을 예방하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, the object of the present invention is to prevent the safety accident and failure by controlling the operation of the washing machine by detecting an abnormal overload during use of the washing machine.

이하, 첨부된 도면을 참조하여 본 발명을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 3을 참조하면, 세탁기의 형상 유지 및 내부보호를 위한 케이스(1)와, 상기 케이스(1) 상면에 부착되어 있는 도어감지스위치(2')와, 상기 케이스(1)의 내부에 설치되어 세탁수를 담는 외조(3)와, 상기 외조(3) 내부에 세탁물을 세탁하도록 설치된 내조(4)와, 상기 내조(4)가 세탁행정을 할수 있도록 회전력을 발생하는 모터(5)와, 상기 모터(5)가 회전하면 이동력을 전달하는 속도변화장치(7)와, 상기 속도변화장치(7) 신호를 통하여 회전을 함으로써 세탁행정을 수행하는 세탁회전판(6)과, 세탁기를 개/폐하는 도어(8)로 구성되어 있다.Referring to FIG. 3, a case 1 for maintaining the shape and internal protection of the washing machine, a door detection switch 2 ′ attached to an upper surface of the case 1, and an inside of the case 1 are installed. An outer tub 3 containing wash water, an inner tub 4 installed to wash laundry in the outer tub 3, a motor 5 for generating rotational force so that the inner tub 4 can be washed, and the When the motor (5) rotates, the speed change device (7) which transmits the moving force, the washing rotary plate (6) performing the washing stroke by rotating through the speed change device (7) signal, and opening / closing the washing machine Is composed of a door (8).

상기와 같이 구성된 세탁기의 동작을 살펴보면 다음과 같다.Looking at the operation of the washing machine configured as described above are as follows.

세탁기가 세탁행정을 시작하면 상기 모터(5)가 회전하여 속도변화장치(7)를 구동시켜 세탁회전판(6)이 회전하게 된다.When the washing machine starts the washing stroke, the motor 5 rotates to drive the speed change device 7 so that the washing rotating plate 6 rotates.

상기 모터(5)가 온을 하면 모터(5)와 세탁회전판(6) 모두 회전을하고, 상기 모터(5)가 오프하더라도 세탁회전판(6)은 일정시간만큼 계속 회전을 하게된다.When the motor 5 is turned on, both the motor 5 and the washing rotating plate 6 rotate, and even if the motor 5 is off, the washing rotating plate 6 continues to rotate for a predetermined time.

이와 같이, 상기 세탁회전판(6)이 관성에 의하여 회전을 하는동안 모터(5)도 회전을 하게되며, 이 회전에 의해 모터(5) 내부에 있는 코일(L)과 모터(5) 기동용 캐패시터(C)에 의해 잔류기전력이 발생된다.As such, while the washing rotary plate 6 rotates by inertia, the motor 5 also rotates, and the rotation of the coil L and the capacitor for starting the motor 5 is performed by the rotation. Residual electromotive force is generated by (C).

상기 내조(4)에 세탁물(13)의 양이 적으면 세탁물(13)이 세탁회전판(6)을 누르는 힘이 작기 때문에 모터(5)를 오프시키더라도 세탁회전판(6)은 관성에 의해 오랫동안 회전하므로 잔류기전력이 유지되는 시간이 길다.If the amount of the laundry 13 in the inner tank 4 is small, the force of the laundry 13 to press the laundry rotating plate 6 is small, so even when the motor 5 is turned off, the laundry rotating plate 6 rotates for a long time due to inertia. Therefore, the time that the residual electromotive force is maintained is long.

이와 반대로, 상기 내조(4)에 세탁물(13)의 양이 많으면 세탁물(13)이 세탁회전판(6)을 누르는 힘이 크므로, 모터(5) 오프후에는 짧은 시간동안만 세탁회전판(6)이 회전하여 잔류기전력이 유지되는 시간이 짧아진다.On the contrary, if the amount of the laundry 13 in the inner tank 4 is large, the force of the laundry 13 to press the laundry rotating plate 6 is large, so that after the motor 5 is turned off, the laundry rotating plate 6 only has a short time. This rotation shortens the time for which the residual electromotive force is maintained.

따라서, 세탁물(13)의 양에 따라 모터(5) 오프후에 잔류기전력이 유지되는 시간 차이가 발생된다.Accordingly, a time difference occurs in which residual electromotive force is maintained after the motor 5 is turned off according to the amount of the laundry 13.

본 발명에 따른 세탁기의 이상 과부하 제어장치 회로는 도 4에 나타낸 바와 같이, 도어열림을 감지하는 도어감지스위치(2')와, 상기 도어감지스위치(2')의 신호를 입력받아 모터(5)동작 제어신호를 출력하는 마이콤(12)과, 상기 마이콤(12)의 제어신호를 입력받아 모터(5)를 구동하는 모터구동부(9)와, 상기 모터구동부(9)의 트라이액의 접점에서 출력되는 신호를 입력받아 아날로그 신호를 디지털 신호로 변환시켜주는 컨버터부(10)와, 상기 컨버터부(10)에서 출력된 신호를 입력받아 증폭시켜 마이콤(12)에 입력시켜주는 증폭부(11)로 구성된다.As shown in FIG. 4, the abnormal overload control device circuit of the washing machine according to the present invention receives a door detection switch 2 'and a signal from the door detection switch 2' to detect the door opening. A microcomputer 12 for outputting an operation control signal, a motor driver 9 for driving the motor 5 in response to the control signal of the microcomputer 12, and outputs at a triac contact point of the motor driver 9. A converter unit 10 for receiving an input signal and converting an analog signal into a digital signal, and an amplifier unit 11 for receiving and amplifying the signal output from the converter unit 10 and inputting the signal to the microcomputer 12. It is composed.

이와 같이 구성된 세탁기의 이상 과부하 제어장치는, 도어감지스위치(2')가 온 상태이면 마이콤(12)의 입력단자(P5)에 0V가 인가되어 모터(5) 동작신호 출력단자(O3,O4)에서 신호가 출력되어 모터(5)와 세탁회전판(6)이 동작된다.In the abnormal overload control device of the washing machine configured as described above, when the door detection switch 2 'is turned on, 0 V is applied to the input terminal P5 of the microcomputer 12 so that the motor 5 operation signal output terminals O3 and O4 are applied. The signal is output from the motor 5 and the washing rotating plate 6 is operated.

이와 반대로, 도어감지스위치(2')가 오프 상태이면 마이콤(12)의 입력단자(P5)에 5V 가 인가되어 모터(5) 동작신호 출력단자(O3,O4)에서 모터(5) 구동신호가 출력되지 않으므로 모터(5)와 세탁회전판(6) 모두 동작을 정지한다.On the contrary, when the door detection switch 2 'is in the off state, 5V is applied to the input terminal P5 of the microcomputer 12 so that the driving signal of the motor 5 from the motor 5 operation signal output terminals O3 and O4 is reduced. Since it is not output, both the motor 5 and the washing rotary plate 6 stop operation.

상기 세탁회전판(6)이 관성에 의하여 회전을 하면 모터(5)도 회전을 하게되는데, 이 회전에 의하여 모터(5) 내부의 코일(L)과 모토 기동용 캐패시터(c)에 의하여 A,B지점에 도 5a와 같은 잔류기전력이 발생된다.When the washing rotary plate 6 is rotated by inertia, the motor 5 is also rotated, and by this rotation, the coil L and the moto starting capacitor c inside the motor 5 cause A, B to rotate. At this point, residual electromotive force as shown in FIG. 5A is generated.

또한, 상기 도 5a와 같은 파형은 컨버터부(10)에서 변환되어 도 5b와 같은 파형으로 출력되며, 모터(5)를 온 상태에서 오프상태로 변환시에 잔류기전력이 발생됨을 알 수 있다.In addition, the waveform as shown in FIG. 5A is converted by the converter unit 10 and output as the waveform as shown in FIG. 5B, and it can be seen that residual electromotive force is generated when the motor 5 is converted from the on state to the off state.

이와 같이 구성된 본 발명에 따른 세탁기의 이상 과부하 제어장치의 동작을 살펴보면 도 6에 도시된 바와 같다.Looking at the operation of the abnormal overload control device of the washing machine according to the present invention configured as described above is as shown in FIG.

먼저, 세탁기의 세탁행정 및 헹굼행정이 시작되면(S1), 상기 세탁행정 및 헹굼행정중에 과부하인가 여부를 확인한다(S2).First, when the washing stroke and the rinsing stroke of the washing machine starts (S1), it is checked whether the washing stroke and the rinsing stroke are overloaded (S2).

상기 과부하가 인가되지 않았으면 계속하여 세탁행정을 수행한다(S3).If the overload is not applied to continue the washing administration (S3).

상기 과부하가 인가되었으면 도어 열림상태를 확인한다(S4).If the overload is applied to determine the door open state (S4).

상기 도어가 열림상태이면 세탁행정을 모두 정지하고(S5), 도어 열림 상태가 아니면 계속하여 세탁행정을 수행한다.If the door is in an open state, all washing administrations are stopped (S5), and if the door is not in an open state, washing is continued.

상기 도어가 열려있는 상태는 도어의 힌지 끝부분(2'b)이 도어감지스위치(2')의 레버(2'a)를 밀지 못하기 때문에 도어감지스위치(2') 내부 접점이 오프되므로 마이콤이 도어열림을 감지하게 된다.In the open state of the door, since the hinge end portion 2'b of the door cannot push the lever 2'a of the door detection switch 2 ', the internal contact of the door detection switch 2' is turned off, so the microcomputer The door is opened.

상기 도어가 열려있는 상태일경우에는 세탁행정도중 과부하를 투입한 것으로 판단하여 세탁기 동작을 정지시키는 것이고, 도어의 열림이 감지되지 않았으면 세탁행정중 세탁물의 꼬임에 의한 일시적인 과부하로 판단하여 계속적으로 세탁행정을 수행하는 것이다.When the door is open, the washing machine stops the operation by judging that an overload has been put into the washing line. If the door is not opened, the washing machine judges it as a temporary overload due to the twisting of the laundry during the washing process. It is to carry out the administration.

본 발명은 세탁기의 세탁행정중 과부하를 감지하여, 이상 과부하가 감지될 경우 세탁기의 동작을 정지시킴으로써 안전사고 및 고장발생을 미연에 방지할 수 있는 효과가 있다.The present invention detects an overload during the washing administration of the washing machine, and when an abnormal overload is detected, the safety accident and failure can be prevented in advance by stopping the operation of the washing machine.
