Description

세탁기 뚜껑 잠금장치{LID LOCK S/W}  Washing machine lid lock {LID LOCK S / W}

본 기술은 통돌이 세탁기 뚜껑 잠금장치로서 지금까지는 세탁기 탈수행정에서  This technology is a lid washer lid lock so far in washing machine dehydration

세탁기 뚜껑을 열면 세탁기 자체 브레이크 장치로 세탁조를 정지 시켰으나   When I opened the washing machine lid, I stopped the washing tank with the washing machine's own brake device.

대용량 세탁기에서는 세탁조의 회전 관성에 의해서 곧바로 정지가 되지 않아  In large-capacity washing machine, it is not stopped immediately by rotational inertia of washing tank

안전사고에 문제가 있었다   There was a problem with a safety accident.

이를 보완하기 위하여 세탁기 본체에 뚜껑 잠금장치를 설치하여 세탁조가   In order to compensate for this, the washing tank is installed by installing a lid lock on the washing machine body.

완전히 정지한 후에 세탁기 뚜껑을 열리게 하여 안전사고를 방지함에 그 목적이 있다 특히 대용량 세탁기에서는 안전규격이 강화되어 규격에 만족하지 않으면  The purpose of this is to prevent the safety accident by opening the lid of the washing machine after stopping completely. Especially in large-capacity washing machines, if the safety standard is reinforced and it is not satisfied

세탁기 생산이 불가능하다  Washing machine production is impossible

종래의 세탁기는 세탁 후 탈수행정에서 세탁기 뚜껑을 열면 세탁조의 회전력이  In conventional washing machines, when the washing machine lid is opened in a dehydration cycle after washing, the rotational force of the washing tank is reduced.

관성에 의하여 일정 시간이 지난 후 정지를 한다 만약 세탁기 사용자가 세탁조가 정지하기 전에 세탁물을 꺼내기 위하여 손을 넣으면 안전사고가 발생할 수 있다  Stop after a certain amount of time due to inertia. If the washing machine user puts his hand to remove the laundry before the washing tank stops, a safety accident may occur.

이를 방지하기 위하여 세탁기의 세탁조가 완전히 정지하고 나서 세탁기 뚜껑을  To prevent this, close the washing machine lid after the washing tank in the washing machine has stopped completely.

열리게 하는 안전 장치를 고안하기 위함이다 To devise a safety device that opens.

종래의 기술(도7)은 솔레노이드 전자변을 이용하여 세탁기 뚜껑 개폐장치를   The prior art (FIG. 7) uses a solenoid solenoid valve to open and close the lid of a washing machine.

해왔으나 작동시 전자변 소음이 발생하고 작동행정이 길어지면 솔레노이드   However, if the solenoid is generated during operation and the operation stroke is long, the solenoid

철심이 복귀되지 않는 문제점이 있었다 또한 잠김상태에서는 솔레노이드에   There was a problem that the iron core did not return.

계속적으로 전원이 인가 할 수 없으므로 잠금장치 작동후 레바 복귀 보조장치가 필요했다   Since the power could not be continuously applied, a lever return assistance device was needed after the locking device was activated.

본 고안은 이와 같은 종래의 문제점을 해결하기 위한 것으로서 본 고안의 주된 특징은 슬라이드 잠금 레바(8)가 DC모터(2)와 연계된 유성기어(4)와 래크기어  The present invention is to solve such a conventional problem, the main feature of the present invention is the slide lock lever (8) planetary gear (4) and rack gear associated with the DC motor (2)

(6)에 의해 구동되고 구동된 슬라이드 잠금레바는 슬라이드 잠금레바와 연계되어 설치된 내부접점 신호의 출력에 의해 세탁기에서 위치제어가 되어 전원이   The slide lock lever driven and driven by (6) is positioned in the washing machine by the output of an internal contact signal installed in conjunction with the slide lock lever, thereby providing power.

OFF되고 전원이 OFF되면 슬라이드 잠금레바는 동작된 위치에서 감속된 기어비와 비례하여 복귀 역회전 토오크가 발생되어 전원이 재인가 되기 전까지 유지가   When it is turned off and the power is turned off, the slide lock lever is maintained until the power is reapplied due to the return reverse torque generated in proportion to the decelerated gear ratio in the operated position.

된다 슬라이드 잠금레바의 복귀는 세탁기 조작부의 세탁조 완전 정지 신호에   The return of the slide lock lever is caused by the washing tank full stop signal of the washing machine control unit.

의해 DC모우터에 역방향 전원이 인가되면 상기와 반대로 슬라이 잠김드레바가   When the reverse power is applied to the DC motor, the slide lock lever

작동되어 잠금이 해제된다  Is activated and unlocked

이상에서 설명한 바와 같이 본 고안의 세탁기 뚜껑 잠금장치는 소형 DC모터의  As described above, the washing machine lid locking device of the present invention is a small DC motor.

고속회전을 유성기어로서 감속제어되고 감속비에 비례적으로 증가하는   High speed rotation is controlled by planetary gear and increases in proportion to reduction ratio.

회전토크를 유성기어의 피니온에 연결된 래크기어를 전달시켜 슬라이드   Slide the rotating torque to transmit the rack gear connected to the pinion of the planetary gear

잠김레바 작동력은 크게하고 이와 반대로 역방향의 복귀력은 강하게 하여   The locking lever actuation force is increased and the reverse force is reversed.

세탁기 탈수진동에 의한 자연 복귀를 방지하고 모터의 회전운동을 슬라이드  Prevents natural return by washing machine dehydration vibration and slides motor rotation

잠김레바의 개폐 왕복운동으로 용이하게 제어할 수 있다   Can be easily controlled by opening and closing reciprocating movement of locking lever

또한 슬라이드 잠김레바와 연계된 슬라이드 방식의 접점은 레바 잠김상태를   In addition, the slide-type contacts associated with the slide locking lever prevent the lever locking state.

아주 용이하게 세탁기 조작장치에 출력할 수 있는 특징이 있다  There is a feature that can be easily output to the washing machine control unit
