In addition, a driving motor 16 is installed at the lower end of the drum 11 to drive the rotating tub 13.

이러한 드럼(11)은 본체(10)내에 네 개의 현가스프링(14)을 통해 본체(10)내에 장착된다. 즉, 현가스프링(14)을 통해 드럼(11)의 상단이 본체(10)의 상부에 매달려 설치된다. 그리고 드럼(11)의 하단은 완충기(15)에 의해 지지된다. 완충기(15)는 드럼(11)의 하단을 본체(10) 저면으로부터 이격되게 지지하도록 봉상으로 마련된다.This drum 11 is mounted in the main body 10 through four string springs 14 in the main body 10. That is, the upper end of the drum 11 is suspended from the upper portion of the main body 10 through the suspension gas spring 14. The lower end of the drum 11 is supported by the shock absorber 15. The shock absorber 15 is provided in a rod shape to support the lower end of the drum 11 spaced apart from the bottom of the main body 10.

회전조(13)에는 내벽 전역에 걸쳐 탈수공이 천공되어 있고, 내측으로 돌출되게 이루어져 세탁물을 끌어올려 낙하시키는 리프터가 다수개 마련된다. 그리고 구동모터(16)의 동력을 전달받아 이러한 회전조(13)를 구동시키기 위해 회전축(미도시)과 풀리(미도시)가 드럼(11) 측단부위에 연장 배치되고, 벨트(17)를 매개로 풀리와 구동모터(16)가 연결된다. 미설명부호 18은 세탁수 배출을 안내하는 배수호스이며, 이 배수호스(18)의 하류측에는 드럼(11)내의 세탁수를 강제로 배수시키기 위한 배수펌프(19)가 마련된다.The rotating tub 13 is provided with a plurality of lifters for drilling the dehydration hole over the entire inner wall and protruding inward to lift and drop the laundry. In addition, a rotation shaft (not shown) and a pulley (not shown) are extended to the drum 11 side end portion to drive the rotary tub 13 by receiving the power of the driving motor 16, and the belt 17 is mediated. The pulley and the drive motor 16 are connected. Reference numeral 18 denotes a drain hose for guiding the discharge of the wash water, and a drain pump 19 for forcibly draining the wash water in the drum 11 is provided downstream of the drain hose 18.

그리고 본체(10)의 전면에는 회전조(13) 내로 세탁물을 투입하거나 꺼내기 위한 투입구(10a)와, 투입구(10a)를 개폐할 수 있도록 도어(20)가 힌지결합되어 있다. 도어(20)에는 투입구를 닫은 상태에서도 회전조(13) 내부를 볼 수 있도록 그라스 성형된 투시부재(21a)가 마련된다.And the front of the main body 10 is an inlet (10a) for introducing or removing the laundry into the rotating tub 13, the door 20 is hinged to open and close the inlet (10a). The door 20 is provided with a glass-shaped see-through member 21a so that the inside of the rotating tub 13 can be seen even when the inlet is closed.

도 2를 참조하면, 도어(20)는 본체(10) 전면에 회전운동 가능하게 장착되며 투시부재(21a)가 고정되는 도어홀더(21)와, 도어홀더(21)의 전면을 감싸도록 결합되는 도어커버(22)와, 본체(10) 내부에 걸려 도어(20)의 닫힘상태를 유지하는 걸림돌기(23)를 구비한다.Referring to FIG. 2, the door 20 is rotatably mounted on the front surface of the main body 10 and coupled to surround the front surface of the door holder 21 and the door holder 21 to which the see-through member 21a is fixed. The door cover 22 and the locking protrusion 23 which is caught inside the main body 10 and maintains the closed state of the door 20 are provided.

걸림돌기(23)는 일단이 핀(25)을 통해 도어홀더(21)에 회전운동 가능하게 결합되며 도어(20)의 닫힘 시 본체(10)내에 탄성적으로 걸리도록 구성된다. 핀(25)은 도어홀더(21)에 브래킷(26)을 통해 양단이 설치된다. 브래킷(26)은 나사(27)를 통해 도어홀더(21)에 장착된다. 또한, 걸림돌기(23)의 걸림상태를 해제시키기 위해 일단이 걸림돌기(23)의 일단부와 함께 핀(25) 결합되어 이를 중심으로 회전운동 가능하게 설치된 도어핸들(24)이 마련된다. 도어핸들(24)은 걸림돌기(23)를 탄성지지하도록 도어홀더(21)에 나사(29)결합된 판스프링(28)을 통해 복원된다.The locking protrusion 23 is rotatably coupled to the door holder 21 through one end of the pin 25, and configured to elastically engage in the main body 10 when the door 20 is closed. The pin 25 is installed at both ends of the door holder 21 through the bracket 26. The bracket 26 is mounted to the door holder 21 via a screw 27. In addition, one end is coupled to the pin 25 together with one end of the locking protrusion 23 to release the locking state of the locking protrusion 23, and a door handle 24 is installed to be rotatable about it. The door handle 24 is restored through a leaf spring 28 coupled to the door holder 21 with a screw 29 so as to elastically support the locking protrusion 23.

이러한 걸림돌기(23)를 갖춘 도어(20)는 도 3에 도시한 바와 같이, 본체(10)내에 구성된 도어잠금장치를 통해 개폐가 제어된다. 이 도어잠금장치는 바이메탈(30)과, 바이메탈(30)에 의하여 작동하는 잠금봉(31)과, 잠금봉(31)의 작동으로 본체(10)내로 삽입된 걸림돌기(23)를 구속하는 철판(32)을 구비한다. 바이메탈(30)은 전원(34)을 공급받아 작동하는데, 전원공급을 제어하기 위한 마이크로스위치(33)가 배치된다.As shown in FIG. 3, the door 20 having such a locking protrusion 23 is controlled to be opened and closed through a door locking device configured in the main body 10. The door locking device includes a bimetal 30, a locking rod 31 operated by the bimetal 30, and an iron plate restraining the locking protrusion 23 inserted into the main body 10 by the operation of the locking rod 31. (32) is provided. The bimetal 30 operates by being supplied with the power 34, and a micro switch 33 for controlling the power supply is disposed.

따라서 사용자가 도어(20)를 본체(10)측으로 밀어 닫으면, 마이크로스위치(33)를 연결시켜 바이메탈(30)이 작동되고, 아울러 잠금봉(31)이 전진하여 철판(32)의 이동을 방지함으로써, 세탁기의 작동 중에는 도어(20)가 열리지 않는다.Therefore, when the user slides the door 20 toward the main body 10, the bimetal 30 is operated by connecting the micro switch 33, and the locking rod 31 is moved forward to prevent the movement of the iron plate 32. The door 20 is not opened while the washing machine is in operation.

그리고 세탁이 완료되고 전원공급이 중단되면, 바이메탈(30)은 약 90초 이내에 본래의 상태로 복원되어 도어(20)의 개폐가 가능하게 된다. 이 때, 도어(20)의 개방동작은 사용자가 도어핸들(24)을 당김에 따라 이루어진다. 즉, 도어핸들(24)을 당기면 걸림돌기(23)는 판스프링(28)을 밀면서 일측으로 회전하고 철판(32)으로부터 이탈됨으로써, 도어(20)가 개방된다.When the washing is completed and the power supply is stopped, the bimetal 30 is restored to its original state within about 90 seconds to enable the opening and closing of the door 20. At this time, the opening operation of the door 20 is performed as the user pulls the door handle 24. That is, when the door handle 24 is pulled, the locking protrusion 23 rotates to one side while pushing the leaf spring 28 and is separated from the iron plate 32, thereby opening the door 20.

그러나 종래 드럼세탁기의 도어(20)는 걸림돌기(23)의 설치를 위한 부품수가 많아 조립 생산성이 저하됨은 물론이고, 제조비용의 상승요인이 된다.However, the door 20 of the conventional drum washing machine has a large number of parts for the installation of the locking protrusion 23, as well as the assembly productivity is lowered, and the manufacturing cost increases.

또한, 드럼세탁기의 작동 중에 전원공급이 차단될 경우, 즉 정전사고 시 바이메탈(30)이 동작하지 않게 된다. 따라서 정전 중에 사용자가 무의식적으로 도어 핸들(24)을 잡아당기면 드럼(11)내에 물이 차있는 상태에서도 도어(20) 개방작동이 이루어지는 문제점이 있다.In addition, when the power supply is cut off during the operation of the drum washing machine, that is, the bimetal 30 does not operate during an electrostatic accident. Therefore, when the user unconsciously pulls the door handle 24 during a power failure, there is a problem that the door 20 is opened even when the drum 11 is filled with water.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 도어 잠금상태를 유지하는 구성부품을 단순화하여 조립을 용이하게 하고 제조비용을 절감하며, 드럼세탁기의 작동 중에 전원공급이 차단되어도 도어의 개폐작동 안정성을 보다 향상시킬 수 있는 드럼세탁기의 도어잠금장치를 제공하는 것이다.The present invention is to solve this problem, the object of the present invention is to simplify the components to maintain the door lock state to facilitate assembly and reduce the manufacturing cost, even if the power supply is cut off during the operation of the drum washing machine It is to provide a door lock of the drum washing machine that can further improve the opening and closing operation stability.

다음에는 이와 같이 구성된 본 발명에 따른 도어잠금장치의 작동 및 효과를 설명한다.Next will be described the operation and effect of the door locking device according to the present invention configured as described above.

먼저, 사용자가 회전조(53)내에 세탁물을 투입한 후 도어(60)를 닫고 드럼세탁기를 작동시키면, 세제가 용해된 세탁수가 드럼(51)과 회전조(53) 내부로 유입된다. 그리고 사용자가 선택한 세탁코스에 따라 세탁과 헹굼 및 탈수행정이 이루어진다.First, when a user puts laundry into the rotating tank 53 and then closes the door 60 and operates the drum washing machine, the washing water in which detergent is dissolved is introduced into the drum 51 and the rotating tank 53. In addition, washing, rinsing, and dehydration are performed according to the washing course selected by the user.

이러한 세탁이나 탈수행정중에는 도어잠금장치(70)에 의해 도어(60)가 닫힘 상태로 유지되기 때문에 이의 개방이 불가능하다. 이를 보다 상세하게 설명하면 다음과 같다.During such washing or dehydration administration, since the door 60 is kept closed by the door locking device 70, the opening thereof is impossible. This will be described in more detail as follows.

우선, 사용자가 도어(60)를 개방하고자 하는 경우에는 스위치(미도시)를 인위적으로 작동시켜 동기모터(71)를 구동시키면, 도 7에 도시한 바와 같이, 회전판(73)이 일방향으로 90도 회전한다. 이 때, 걸림봉(72)의 지지돌기(72b)가 회전돌기(73a)에 걸리기 때문에, 회전판(73)이 회전함에 따라 걸림봉(72)은 스프링(74)을 압축시키면서 후진 (화살표 A방향)하며, 걸림돌기(63)의 턱(63a)으로부터 걸림봉(72)의 홈부(72a)가 이탈된다. 이로 인해 걸림돌기(63)는 걸림상태가 해제되어 자유롭게 방치되기 때문에, 도어(60)를 쉽게 개방할 수 있다.First, when the user wants to open the door 60, when the synchronous motor 71 is driven by artificially operating a switch (not shown), as shown in FIG. 7, the rotating plate 73 is 90 degrees in one direction. Rotate At this time, since the support protrusion 72b of the locking bar 72 is caught by the rotation protrusion 73a, as the rotating plate 73 rotates, the locking bar 72 compresses the spring 74 and moves backward (arrow A direction). The groove portion 72a of the locking bar 72 is separated from the jaw 63a of the locking projection 63. As a result, since the locking projection 63 is released and freely left, the door 60 can be easily opened.

그리고 사용자가 도어(60)를 닫고 스위치를 재작동시켜 동기모터(71)를 구동시키면, 회전판(73)은 일방향으로 회전하여 회전돌기(73)로부터 걸림봉(72)의 지지돌기(72b)가 이탈된다. 즉, 회전판(73)이 회전함에따라 곡면으로 이루어진 회전돌기(73)로부터 지지돌기(72b)가 용이하게 이탈되며, 동시에 걸림봉(72)은 스프링(74)의 탄성 지지력에 의해 관통공(70b)을 통해 케이스(70a) 외부로 연장된 상태로 유지된다. 이러한 걸림봉(72)의 전진(화살표 B방향)으로 인해 걸림봉(72)의 홈부(72a)가 걸림돌기(63)의 턱(63a)에 걸려서 걸림돌기(63)가 구속된 상태로 유지됨으로써, 도어(60)가 잠기게 된다.When the user closes the door 60 and restarts the switch to drive the synchronous motor 71, the rotating plate 73 rotates in one direction so that the supporting protrusion 72b of the locking bar 72 is rotated from the rotating protrusion 73. Departure. That is, as the rotating plate 73 rotates, the support protrusion 72b is easily detached from the rotating protrusion 73 formed of a curved surface, and at the same time, the locking bar 72 is penetrated by the elastic support force of the spring 74. It is maintained in the extended state through the case (70a). Due to the advance of the locking bar 72 (arrow B direction), the groove 72a of the locking bar 72 is caught by the jaw 63a of the locking protrusion 63 so that the locking protrusion 63 is held in a restrained state. The door 60 is locked.

이 때, 걸림봉(72)은 스프링(74)에 의해 탄성 지지되어 있기 때문에, 세탁기에 전원공급이 중단되어도 도어(70)의 잠김상태는 그대로 유지된다.At this time, since the locking bar 72 is elastically supported by the spring 74, even if the power supply to the washing machine is stopped, the locked state of the door 70 is maintained as it is.

한편, 이러한 도어잠금장치(70)는 사용자의 스위치 조작에 따라 작동할 수 있게 구성한 것을 예로 하여 설명하였지만, 이에 국한하지 않고 드럼(51)내의 수위를 감지하는 수위감지센서(미도시)와 상호연계하여 도어잠금장치(70)가 작동되게 구성할 수 있다. 이러한 경우에는 별도의 마이크로스위치를 구비하고, 드럼(51)내의 수위가 소정량만큼 담수되면 동기모터(71)를 작동시켜 걸림봉(72)과 걸림돌기(63)의 턱(63a)이 서로 결합되도록 회전판(73)을 회전시키도록 구성한다.On the other hand, the door lock device 70 has been described as an example that can be configured to operate according to the user's switch operation, but is not limited to this interconnected with a water level sensor (not shown) for detecting the water level in the drum 51 The door lock device 70 can be configured to operate. In this case, a separate micro switch is provided, and when the water level in the drum 51 is desalted by a predetermined amount, the synchronous motor 71 is operated to engage the engaging rod 72 and the jaws 63a of the engaging projection 63 with each other. The rotating plate 73 is configured to rotate as possible.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 드럼세탁기의 도어잠금 장치에 의하면, 도어의 걸림돌기를 선택적으로 구속하는 걸림봉의 작동구조가 케이스내에 콤팩트하게 이루어져 조립 생산성이 향상됨은 물론이며, 동시에 제조비용을 보다 절감시킬 수 있다. 또한, 정전사고 등으로 인해 드럼세탁기에 전원공급이 중단되어도 스프링에 의해 도어의 잠김상태가 그대로 유지됨으로써, 세탁기의 작동안 정성 역시 향상되는 이점이 있다.As described in detail above, according to the door lock device of the drum washing machine according to the present invention, the operating structure of the locking rod to selectively restrain the locking projection of the door is compact in the case to improve the assembly productivity, and at the same time increase the manufacturing cost You can save more. In addition, even if the power supply to the drum washing machine is stopped due to an electrostatic accident, the locked state of the door is maintained as it is by the spring, the operation stability of the washing machine is also improved.
