Description

이조식 세탁기의 탈수도어 로킹장치Dewatering Door Locking Device

본 발명은 이조식 세탁기의 탈수조에 괸한 것으로, 특히 탈수조가 탈수모터의 동력이나 또는 관성에 의해 회전중일 경우에는 도어가 로킹상태로 유지되도록 하고 탈수 타이밍 완료후 일정시간이 경과하여 탈수조가 완전 정지된 시점에서 도어로킹이 해제되도록 함으로써 세탁기 사용자가 부주의로 인한 상해의 위험을 근본적으로 배제시키기 위한 이조식 세탁기의 탈수도어 로킹장치에 관한 것이다.The present invention relates to a dehydration tank of a two-type washing machine, and in particular, when the dehydration tank is being rotated by the power or inertia of the dehydration motor, the door is kept in a locked state and the dehydration tank is completely stopped after a certain time after the completion of the dehydration timing. It relates to a dewatering door locking device of a double-type washing machine for allowing the washing machine user to fundamentally exclude the risk of injury due to carelessness by allowing the door locking to be released at the time.

이조식 세탁기는 탈수조와 세탁조를 분리하여 설계한 세탁기로써, 일조식 전자동 세탁기에 비해 전기소모량과 세탁수의 소비량을 현저히 줄일 수 있을 뿐만아니라 세탁 및 탈수코스 등을 사용자 임의로 선택할 수 있어 세탁과정을 부분적으로만 실행시키고자 하는 경우에 매우 유리하다.This washing machine is a washing machine designed by separating the dehydration tank and the washing tank. It can not only reduce the electricity consumption and the consumption of washing water significantly, but also the washing and dehydration courses can be selected by the user in comparison with the automatic washing machine. This is very advantageous if you only want to run it.

일반적인 이조식 세탁기의 전면패널 상에는 세탁 및 탈수 조건 설정을 위한 타이머 조절기와 모드선택기가 마련되고 있다.On the front panel of a general two-type washing machine, a timer controller and a mode selector for setting washing and dehydration conditions are provided.

여기에서 타이머는 세탁모드의 운전시간과 탈수모드의 운전시간을 각각 설정할 수 있는 선택기로서, 이 선택기의 손잡이를 그 둘레에 표시된 원하는 숫자(분을 의미함)에 위치시키면 그 내부의 타이머장치가 작동하여 설정된 시간동안 탈수운전시한 접점 또는 세탁운전시한 접점을 발생하게 된다.Here, the timer is a selector that can set the operation time of the washing mode and the dehydration mode, respectively, and when the knob of the selector is positioned at the desired number (meaning minute) displayed around it, the timer device inside is operated. Thus, during the set time, a contact during dehydration operation or a contact during washing operation is generated.

상기 타이머 옆의 세탁/탈수선택기는 세탁 및 탈수 공통포지션과 세탁포지션과 탈수포지션을 가지며, 세탁/탈수선택기 옆에 배치되는 배수선택기는 오프포지션과 세탁포지션과 배수포지션을 가진다.The washing / dehydration selector next to the timer has a common washing and dehydration position, a washing position and a dehydration position, and a drain selector disposed next to the washing / dehydration selector has an off position, a washing position and a draining position.

이러한 종래의 이조식 세탁기의 동작과정을 보면, 세탁기 사용자가 세탁물을 세탁하고자 하는 경우에 세탁조에 세탁물과 세탁수를 공급한 후 세탁/탈수 선택기와 배수선택기를 각각 세탁포지션에 위치 시킨 다음 타이머를 원하는 시간에 위치시키면, 세탁모터에는 타이머의 메인접점과 세탁/탈수 선택기의 세탁포지션 스위치의 접점과 상기 타이머의 스위칭 접점을 거쳐 상용 AC입력전압이 정,역 구동전압으로 인가되므로 이 세탁모터에 결합된 펄세이터가 회전하는 것에 의해 세탁운전이 주어진 설정시간동안 진행되게 된다.In the operation process of the conventional two-type washing machine, when the user of the washing machine wants to wash the laundry, after supplying the laundry and the washing water to the washing tank, the washing / dehydration selector and the drain selector are respectively positioned at the washing position, and then a timer is desired. When placed in time, the washing motor is connected to the washing motor because the commercial AC input voltage is applied as the forward and reverse driving voltage through the main contact of the timer, the washing position switch of the washing / dehydration selector, and the switching contact of the timer. The rotation of the pulsator causes the washing operation to proceed for a given set time.

이때 오버플로우되는 세탁수는 배수선택기의 세탁포지션에서 온 접점을 발생하는 스위치에 의해 배수펌프모터가 구동하는 것으로 외부로 배출되게 된다.At this time, the overflowed washing water is discharged to the outside by driving the drain pump motor by a switch for generating an on contact at the washing position of the drain selector.

이후 세탁모드의 수행완료후 세탁/탈수 선택기를 세탁 또는 탈수 포지션에 위치시키게 되면 그의 탈수포지션 스위치의 접점이 온 되므로 도어스위치의 접점이 온되어 있다면 탈수모터에는 구동전압이 인가되어 탈수운전이 이루어지게 된다.After the washing mode is completed, if the washing / dehydration selector is placed in the washing or dehydration position, the contact of the dehydration position switch is turned on. If the contact of the door switch is turned on, the dehydration motor is supplied with a driving voltage to perform the dehydration operation. do.

이러한 탈수운전모드에서는 배수선택기의 손잡이의 위치에 무관하게 배수펌프모터가 작동하여 배수가 자동으로 이루어지게 된다.In this dewatering operation mode, the drain pump motor operates automatically regardless of the position of the drain selector handle.

도 1은 종래의 탈수 운전제어회로의 구성도로서, 전원(10)은 도어스위치(11)와 타이머(12)의 직렬회로 접점을 통하여 역율보상용 콘덴서(14)가 부착된 탈수모터(13)에 구동전압으로 인가되게 되므로, 상기 탈수모터(13)가 타이머에 의한 탈수운전중이거나 타이머의 설정시간 완료직후의 관성 회전중이라도 탈수도어를 열 수 있게 되기 때문에, 탈수모터(13)에 전원공급이 차단되더라도 탈수조는 계속 회전하게 되어 세탁기 사용자의 부주의로 인한 안전사고의 위험이 있게 된다.1 is a configuration diagram of a conventional dehydration operation control circuit, and the power supply 10 is a dehydration motor 13 to which a power factor correction capacitor 14 is attached through a series circuit contact of a door switch 11 and a timer 12. Since the dehydration motor 13 is open during the dehydration operation by the timer or during the inertia rotation immediately after the completion of the timer setting time, power supply to the dehydration motor 13 is achieved. Even if blocked, the dehydration tank will continue to rotate, there is a risk of safety accidents due to the careless user of the washing machine.

이러한 안전사고의 위험은 외국의 안전규격을 만족시킬 수 없어 제품수출에 막대한 영향을 미치게 된다.The risk of such a safety accident can not satisfy the safety standards of foreign countries, which greatly affects the export of products.

따라서 세탁기의 탈수조가 회전중일 경우에는 도어를 강제로 로킹시켜 주기 위한 기술의 개발이 요망되어 왔다.Therefore, the development of a technology for forcibly locking the door when the dehydration tank of the washing machine is rotating has been desired.

본 발명의 목적은 이조식 세탁기의 탈수조가 회전중인 경우에는 도어가 로킹상태로 유지되다가 탈수조가 완전 정지된 시점에서 도어로킹이 해제되도록 함으로써 세탁기 사용자가 부주의로 인하여 인명피해를 입게될 가능성을 근본적으로 배제시킬 수 있도록 한 이조식 세탁기의 탈수도어 로킹장치를 제공하는데 있다.An object of the present invention is to fundamentally consider the possibility that a washing machine user may be injured due to carelessness by allowing the door lock to be released when the dehydration tank is completely stopped while the dehydration tank of the dual washing machine is rotating. It is to provide a dewatering door locking device of the two-wash washing machine to be excluded.

도 2는 본 발명에 따른 탈수운전시의 도어로킹 장치의 제어회로 구성도이다.Figure 2 is a block diagram of a control circuit of the door locking device during the dehydration operation according to the present invention.

여기에서 참고되는 바와 같이, 도어록 동기모터(17)에는 타이머(16)의 보조 타이밍 접점(16-2)을 통하여 전원(10)의 전압이 인가되게 연결하고, 탈수모터(13)에는 상기 타이머(16)의 주 타이밍 접점(16-1)과 도어 스위치(11)를 통한 전원(10)의 전압이 인가되게 연결한다.As referred to herein, the door lock synchronous motor 17 is connected to the voltage of the power supply 10 through the auxiliary timing contact 16-2 of the timer 16, the dehydration motor 13 is connected to the timer ( The main timing contact 16-1 of FIG. 16 and the voltage of the power supply 10 through the door switch 11 are connected to each other.

The condenser 14 is for improving the power factor of the dewatering motor 13.

도 3은 본 발명에 따른 탈수도어 로킹장치의 구조도이다.3 is a structural diagram of a dewatering door locking device according to the present invention.

여기에 보인 바와 같이, 도어가 열릴 때 도어 회전축(21)을 중심으로하여 하향 회전이동하게 되는 도어 후방의 도어테일(23)하방으로 슬라이딩 블록(20)을 설치하고, 이 슬라이딩 블록(20)은 도어록 동기모터(17)의 회전축에 결합된 케이블에 의해 스프링(19)의 탄력을 가지고 상기 도어록 동기모터(17)의 일정거리 앞에 설치된 스토퍼(18)와 상기 도어테일(23)사이를 수평 이동할 수 있게 설치한다.As shown here, when the door is opened, the sliding block 20 is installed below the door tail 23 behind the door, which is moved downwardly around the door rotation shaft 21, and the sliding block 20 is The spring coupled to the rotating shaft of the door lock synchronous motor 17 has the elasticity of the spring 19 to move horizontally between the stopper 18 and the door tail 23 installed in front of the door lock synchronous motor 17. Install it properly.

탈수조(26)를 회전구동시키며 브레이크 고정판(24)이 마련된 탈수모터(13)의 축에는 드럼커플링(25)을 설치하고 이 드럼 커플링(25)은 장력지지를 위한 스프링을 가지는 브레이크 동기모터(15)에 의해 작동되게 설치한다.A drum coupling 25 is installed on the shaft of the dehydration motor 13 in which the dehydration tank 26 is rotated and the brake fixing plate 24 is provided. It is installed to be operated by the motor (15).

이와 같이 구성되는 본 발명 장치의 동작과정을 상세히 설명하면 다음과 같다.Referring to the operation process of the device of the present invention configured as described above in detail.

먼저 탈수조에 세탁물을 넣고 타이머(16)로 탈수시간을 정한 다음 도어를 닫게 되면 도어 스위치(11)와 타이머(16)의 주 타이밍 접점(16-1)을 통하여 탈수모터(13)에는 전원(10)의 전압이 인가되게 된다. 이에 따라 탈수모터(13)가 고속회전하여 세탁물을 탈수하게 되며, 이때 브레이크 동기모터(15)도 동시에 작동되어 스프링(27)의 탄력을 이기고 케이블을 당겨 탈수모터의 축 둘레에 설치된 드럼 커플링(25)을 벌려줌으로써 탈수모터는 저항없이 회전할 수 있게 되는 것이다.First, the laundry is put in the dehydration tank and the dehydration time is set by the timer 16. When the door is closed, the dehydration motor 13 is connected to the dehydration motor 13 through the main timing contact 16-1 of the door switch 11 and the timer 16. ) Is applied. Accordingly, the dewatering motor 13 rotates at a high speed to dehydrate the laundry. At this time, the brake synchronous motor 15 is also operated at the same time to overcome the elasticity of the spring 27 and pull the cable to connect the drum coupling installed around the shaft of the dewatering motor. 25), the dehydration motor can rotate without resistance.

이와 같은 상태에서 타이머(16)에 의해 설정된 탈수시간이 경과하지 않은 상태에서 세탁기에 설정된 탈수시간이 완료되어 타이머(16)의 주 타이밍 접점(16-1)이 오픈되면 탈수모터(13)와 브레이크 동기모터(15)에 인가되는 전압이 차단되게 되므로, 탈수모터(13)는 관성 회전상태에 놓이게 되고 브레이크 동기모터(15)는 드럼 커플링(25)을 오픈시키기 위해 당기고 있던 케이블이 스프링(27)의 복원력에 의해 복귀되게 되므로 탈수조는 브레이킹이 이루어지게 된다. 이러한 탈수조 회전 구동용 모터의 구동전원 차단 및 브레이크 동작에 의해 탈수조가 완전히 정지하기까지는 수초 내지 수십초의 시간이 필요하다.In this state, when the dehydration time set in the washing machine is completed after the dehydration time set by the timer 16 has not elapsed and the main timing contact 16-1 of the timer 16 is opened, the dehydration motor 13 and the brake are depressed. Since the voltage applied to the synchronous motor 15 is cut off, the dehydration motor 13 is placed in an inertial rotation state, and the brake synchronous motor 15 is pulled by the spring 27 to open the drum coupling 25. The dehydration tank is braking because it is returned by the restoring force of A time of several seconds to several tens of seconds is required until the dehydration tank is completely stopped by the driving power interruption and brake operation of the dehydration tank rotation driving motor.

따라서 타이머(16)에 설정된 탈수 타임이 완료된 직후에 도어를 열게되면 아직 탈수조가 고속으로 회전하고 있는 상태이므로 안전사고의 위험이 있게된다.Therefore, if the door is opened immediately after the dehydration time set in the timer 16 is completed, the dehydration tank is still rotating at a high speed, so there is a risk of a safety accident.

타이머(16)의 보조 타이밍 접점(16-2)은 주 타이밍 접점(16-1)이 열리고 난후 일정시간이 경과한 후에 온 작동되게 되는 접점으로써, 이 접점에 의해 도어록 동기모터(17)를 작동시키게 된다.The auxiliary timing contact 16-2 of the timer 16 is a contact that is turned on after a predetermined time has elapsed after the main timing contact 16-1 is opened, and operates the door lock synchronous motor 17 by this contact. Let's go.

도어록 동기모터(17)는 도 3에서 나타내고 있는 바와 같이, 탈수조의 회전운전중에는 상기 도어록 동기모터의 케이블에 연결되어 있는 슬라이딩 블록(20)이 스프링(19)의 복원력에 의해 밀려나 도어테일(23)에 밀착 접촉하게 되므로 도어 회전축을 중심으로 회전하게 되는 도어테일(23)의 하방회전운동을 저지시키므로 도어가 로킹상태로 유지되게 된다.As shown in FIG. 3, the door lock synchronous motor 17 is pushed by the restoring force of the spring 19 by the sliding block 20 connected to the cable of the door lock synchronous motor during the rotation operation of the dehydration tank. In close contact with the door, the door tail 23 is rotated about the door rotation axis, thereby preventing the downward rotation of the door, so that the door is kept locked.

이와 같은 상태에서 타이머(16)의 보조 타이밍 접점(16-2)이 주 타이밍 접점(16-1)의 타이밍 오프 시점으로부터 일정시간 지연되어 온되는 동작에 따라서, 도어록 동기모터(17)에 전원(10)의 전압이 투입되면 상기 동기모터가 작동하여 스프링(19)의 탄력을 이기고 케이블을 끌어당기게 될 것이므로 슬라이딩 블록(20)이 후방으로 빠져나가게 된다.In such a state, power is supplied to the door lock synchronous motor 17 in accordance with an operation in which the auxiliary timing contact 16-2 of the timer 16 is delayed for a predetermined time from the timing off timing of the main timing contact 16-1. When the voltage of 10) is applied, the synchronous motor is operated to overcome the elasticity of the spring 19 and pull the cable, so that the sliding block 20 is released to the rear.

그러므로 상기 슬라이딩 블록(20)의 후퇴에 따라 도어테일(23)에 의한 도어의 로킹상태가 해제되게 되므로 도어(22)는 열려질 수 있게 된다.Therefore, since the locking state of the door by the door tail 23 is released as the sliding block 20 is retracted, the door 22 may be opened.

상기 타이머(16)는 주 타이밍 접점(16-1)에 의한 탈수 타이밍 완료후 탈수조의 관성회전력과 브레이킹 능력에 따라 탈수조가 완전 정지될 수 있는데 까지 걸리는 수초 내지 수십초가 경과한 다음에 보조 타이밍 접점(16-2)이 온되게 되므로, 탈수조의 관성회전 중에는 도어가 로킹상태를 그대로 유지하게 된다.After completion of the dehydration timing by the main timing contact 16-1, the timer 16 has a number of seconds to several tens of seconds until the dehydration tank can be completely stopped according to the inertia rotational power and the braking capability of the dehydration tank. 16-2) is turned on, so that the door remains locked during the inertia rotation of the dehydration tank.

이상에서 설명한 바와 같은 본 발명은 이조식 세탁기의 탈수조의 도어가 탈수운전 중 및 탈수조의 완전 정지이전까지는 록킹상태로 유지되게 되므로 타이머에 설정된 시간을 강제 타임아웃시킨후 도어를 열게됨으로서 발생될 수 있는 안전사고의 가능성을 근본적으로 배제시키게 되는 특유의 효과를 가져온다.As described above, the present invention can be generated by opening the door after the time set in the timer because the door of the dehydration tank of the dual-type washing machine is kept locked during the dehydration operation and until the dehydration tank is completely stopped. It has the unique effect of fundamentally eliminating the possibility of a safety accident.
