또한, 외조(1)의 하방에는 배수구조가 마련되어 있는데, 이 배수구조는 외조(1)의 하부 소정 영역에 연결호스(11), 배수밸브(12), 배수호스(13) 및 연결편(14)으로 이루어진다.In addition, a drainage structure is provided below the outer tub 1, which has a connection hose 11, a drain valve 12, a drain hose 13, and a connecting piece 14 at a lower predetermined region of the outer tub 1. Is done.
상기 배수구조는 연결레버(15)에 의해 기어모터(16)와 연결되고, 기어모터(16)의 동작에 따라 세탁날개(3)와 세탁조(2)를 정회전 및 역회전으로 동작시킨다.The drainage structure is connected to the gear motor 16 by the connecting lever 15, and operates the washing blade 3 and the washing tank 2 in the forward and reverse rotation according to the operation of the gear motor 16.
이와같이 구성되는 종래 기술에 따른 세탁기의 언발란스 제어장치를 도 2의 회로 구성도를 참조하여 설명하면 다음과 같다.Referring to the circuit diagram of FIG. 2, an unbalance control apparatus for a washing machine according to the related art configured as described above is as follows.
종래 기술에 따른 세탁기의 언발란스 제어장치는 제 1 및 제 2 포트(P1,P2)를 통해 제어신호를 출력하는 제어부(20)와, 제어부(20)의 제 1 포트(P1)에서 출력되는 제어신호에 의해 세탁용모터(8)를 동작시키는 모터 구동부(21)와, 제어부(20)의 제 2 포트(P2)에서 출력되는 제어신호에 의해 배수밸브(12)를 동작시키는 배수밸브 구동부(22)로 구성된다.The unbalance control apparatus for a washing machine according to the prior art includes a control unit 20 for outputting a control signal through the first and second ports P1 and P2 and a control signal output from the first port P1 of the control unit 20. By the motor driving unit 21 for operating the washing motor 8 and the drain valve driving unit 22 for operating the drain valve 12 by a control signal output from the second port P2 of the control unit 20. It consists of.
여기서 모터 구동부(21)는 제어부(20)의 제 1 포트(P1)에서 출력되는 제어신호에 의해 온/오프 동작되는 제 1 트랜지스터(Q1)와, 제 1 트랜지스터(Q1)의 동작에 따라 세탁용모터(8)에 교류전원을 공급하는 제 1 트라이악(TRA1)으로 구성된다.In this case, the motor driving unit 21 is for washing according to the operation of the first transistor Q1 and the first transistor Q1 that are turned on / off by a control signal output from the first port P1 of the control unit 20. It consists of the 1st triac TRA1 which supplies AC power to the motor 8.
또한 배수밸브 구동부(22)는 모터 구동부(21)의 제 1 트랜지스터(Q1) 및 제 1 트라이악(TRA1)과 동일하게 동작되는 제 2 트랜지스터(Q2) 및 제 2 트라이악(TRA2)으로 구성된다.In addition, the drain valve driver 22 includes a second transistor Q2 and a second triac TRA2 which are operated in the same manner as the first transistor Q1 and the first triac TRA1 of the motor driver 21. .
이와같이 구성되는 세탁기의 종래 기술에 따른 언발란스 제어방법을 도 3의 플로우 챠트를 참조하여 설명하면 다음과 같다.The unbalance control method according to the related art of the washing machine configured as described above will be described with reference to the flowchart of FIG. 3.
세탁용모터(8) 및 배수밸브(12)를 동작시켜 헹굼 탈수 또는 본탈수 행정 진행중(S100) 언발란스가 감지되면(S101), 제어부(20)는 제 1 포트(P1)로 로우 신호를 출력함에 따라 모터 구동부(21)의 제 1 트랜지스터(Q1) 및 제 1 트라이악(TRA1)을 오프시킨다. 따라서, 세탁용모터(8)는 정지된다.When the washing motor 8 and the drain valve 12 are operated to detect rinsing dehydration or main dehydration stroke in progress (S100), when an unbalance is detected (S101), the control unit 20 outputs a low signal to the first port P1. Accordingly, the first transistor Q1 and the first triac TRA1 of the motor driver 21 are turned off. Thus, the washing motor 8 is stopped.
또한 제어부(20)는 제 1 포트(P1)로 로우신호를 출력함과 동시에 제 2 포트(P2)에도 로우신호를 출력함에 따라 배수밸브 구동부(22)의 제 2 트랜지스터(Q2) 및 제 2 트라이악(TRA2)이 오프되므로 배수밸브(12)가 차단된다(S102).In addition, the control unit 20 outputs a low signal to the first port P1 and also outputs a low signal to the second port P2, so that the second transistor Q2 and the second trim of the drain valve driver 22 are output. Since the evil TRA2 is turned off, the drain valve 12 is blocked (S102).
위의 단계(S102)에서 세탁용모터(8) 및 배수밸브(12)의 동작이 정지되어 강제적으로 세탁조(2)가 급정지된후 감지한 언발란스를 해제하기 위해 재차 헹굼행정을 진행하고(S103), 언발란스가 해제되면 언발란스에 의해 중단되었던 세탁행정을 계속적으로 수행하여 세탁을 완료한다.In the above step (S102) the operation of the washing motor 8 and the drain valve 12 is stopped and the washing tank 2 is forcibly stopped after the rinsing stroke again to release the detected unbalance (S103) When the unbalance is released, the washing operation which was interrupted by the unbalance is continuously performed to complete the washing.
종래 기술에 따른 세탁기의 언발란스 제어방법은 언발란스가 감지되면 세탁용모터 및 배수밸브의 동작을 동시에 정지시키기 때문에 회전 관성에 의해 세탁조가 여력회전하고 있는 상태에서 강제적으로 세탁조를 급정지시키는 결과를 초래하므로, 세탁기가 심하게 요동하는 문제점이 있다.The unbalance control method of the washing machine according to the prior art stops the operation of the washing motor and the drain valve at the same time when the unbalance is detected, resulting in a forced stop of the washing tank in a state in which the washing tank is rotating by the rotational inertia, There is a problem that the washing machine vibrates badly.
따라서 본 발명은 종래 기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 본 발명은 언발란스 감지시 세탁용모터를 정지시키고 세탁조의 여력회전이 정지되기 위한 일정시간 경과후 배수밸브를 차단하여 세탁조를 정지시키는 세탁기의 언발란스 제어방법을 제공함에 그 목적이 있다.Therefore, the present invention has been made in order to solve the various problems of the prior art, the present invention is to stop the washing motor when detecting the unbalance and to stop the washing tank by blocking the drain valve after a certain period of time to stop the rotation of the washing tank Its purpose is to provide an unbalance control method for a washing machine.

본 발명에 따른 세탁기의 언발란스 제어방법은 세탁기의 헹굼탈수 또는 본탈수 진행시 상기 세탁조의 언발란스가 감지되면 세탁모터를 정지시키고 이 상태를 설정된 시간동안 유지하는 제 1 단계와, 위의 단계에서 설정된 시간이 경과되면 배수밸브를 차단시키고 헹굼을 재진행하는 제 2 단계와, 제 1 단계와 제 2 단계를 반복수행하는 제 3 단계로 이루어짐에 그 특징이 있다.The method for controlling the unbalance of the washing machine according to the present invention comprises the first step of stopping the washing motor and maintaining this state for a predetermined time when the washing tank detects unbalance of the washing tank during rinsing dehydration or main dehydration. When the elapsed time has elapsed, the drain valve is shut off and the rinsing is performed again, and the first step and the third step of performing the second step are characterized in that it consists of repeatedly.
이하, 본 발명에 따른 세탁기의 언발란스 제어방법의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of the unbalance control method of the washing machine according to the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 세탁기의 언발란스 제어장치는 도 2와 동일하고, 도 4는 본 발명에 따른 세탁기의 언발란스 제어를 수행하기 위한 플로우 챠트이다.The apparatus for controlling the unbalance of the washing machine according to the present invention is the same as that of FIG. 2, and FIG. 4 is a flowchart for performing the unbalance control of the washing machine according to the present invention.
도 2 및 도 4를 참조하여 본 발명에 따른 세탁기의 언발란스 제어방법을 설명하면, 세탁용모터(8) 및 배수밸브(12)를 동작시켜 헹굼탈수 또는 본탈수 행정을 진행한다(S200).2 and 4, the unbalance control method of the washing machine according to the present invention will be described. The washing motor 8 and the drain valve 12 are operated to perform a rinsing dehydration or main dehydration stroke (S200).
헹굼탈수 또는 본탈수 행정진행시 언발란스가 감지되면(S201), 제어부(20)는 제 1 포트(P1)로 로우신호를 출력함에 따라 모터 구동부(21)의 제 1 트랜지스터(Q1) 및 제 1 트라이악(TRA1)이 오프되어 세탁용모터(8)는 정지된다(S202).When an unbalance is detected during the rinsing dehydration or the main dehydration stroke (S201), the control unit 20 outputs a low signal to the first port P1, so that the first transistor Q1 and the first try of the motor driving unit 21 are performed. Evil TRA1 is turned off and washing motor 8 is stopped (S202).
그리고, 위의 단계(S202)에서 세탁용모터(8)가 정지된후 회전 관성에 의해 세탁조(2)가 회전하는 여력회전시간(T1)이 경과하면(S203), 제어부(20)는 제 2 포트(P2)로 로우신호를 출력함에 따라 배수밸브 구동부(22)의 제 2 트랜지스터(Q2) 및 제 2 트라이악(TRA2)이 오프되므로 배수밸브(12)가 차단된다(S204).After the washing motor 8 is stopped in the above step S202, when the rotational rotation time T1 of the washing tank 2 rotates due to the rotational inertia (S203), the control unit 20 performs a second operation. Since the second transistor Q2 and the second triac TRA2 of the drain valve driver 22 are turned off as the low signal is output to the port P2, the drain valve 12 is blocked (S204).
이어, 급수후 헹굼행정을 재차 진행하여 감지된 언발란스를 해제한다(S205).Subsequently, after the water supply, the rinsing cycle is performed again to release the detected unbalance (S205).
이와같은 과정을 반복하여 언발란스가 해제되면 진행중이던 세탁행정을 계속 수행하여 세탁기의 전체행정을 완료한다.When the unbalance is released by repeating the above process, the washing administration that is in progress is continued to complete the entire administration of the washing machine.
본 발명에 따른 세탁기의 언발란스 제어방법은 언발란스 발생시 먼저 세탁용모터를 정지시키고 세탁조의 여력회전이 완료된후 배수밸브를 차단하여 세탁조를 서서히 정지시키므로, 세탁조의 급제동에 의한 세탁기의 유동량을 줄일 수 있어 세탁기의 파손 및 소음등을 방지할 수 있는 효과가 있다.The unbalance control method of the washing machine according to the present invention stops the washing motor first when the unbalance occurs and blocks the drain valve after the rotation of the washing tank is completed, so that the washing tank is gradually stopped, thereby reducing the flow amount of the washing machine by the rapid braking of the washing machine. There is an effect that can prevent damage and noise.
