[발명의 분야][Field of Invention]

본 발명은 배수 및 탈수행정의 시작과 종료시에 배수통로상에 구성된 배수밸브를 개폐시켜주는 배수장치를 갖는 전자동 기계식 세탁기에 관한 것으로서, 특히 타이머를 구비한 전자동세탁기에 있어서, 배수밸브 개폐시 충격음발생을 방지한 무충격음 전자동 기계식 세탁기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic mechanical washing machine having a drainage device that opens and closes a drain valve configured on a drain passage at the beginning and the end of drainage and dehydration stroke. Particularly, in a fully automatic washing machine having a timer, an impact sound is generated when the drain valve is opened and closed. It relates to a non-impact sound automatic mechanical washing machine.

[발명의 배경][Background of invention]

일반적으로 전자동 기계식 세탁기는 일조식으로 되어 있으며, 하나의 주모타에 의해서 선택적으로 펄세이터(pulsator)를 회전시키거나 세탁조를 회전시킬 수 있도록 기어 메카니즘 어셈블리(gear mechanism assembly)가 구성되어 있다.In general, a fully automatic mechanical washing machine is a one-piece type, and a gear mechanism assembly is configured to selectively rotate a pulsator or a washing tank by one main motor.

또한, 전자동 기계식 세탁기의 행정구분은 급수행정, 세탁행정, 헹굼행정, 배수행정, 그리고 탈수행정으로 이루어져 있다.In addition, the administrative division of the fully automatic mechanical washing machine consists of water supply administration, washing administration, rinsing administration, drainage administration, and dehydration administration.

상기 각 행정구분에 따른 전기회로의 구성은 급수행정시에는 급수밸브에만 통전시키고, 세탁 또는 헹굼행정시에는 전자동 기계식 타이머에서 주모타로 전기를 통전시키고, 배수행정시에는 타이머에서 솔레노이드에만 통전시켜 배수밸브를 개방시키고, 탈수행정시에는 주모타와 솔레노이드에 통전시켜 배수밸브를 개방시킴과 동시에 세착조를 회전시키도록 되어 있다.The configuration of the electric circuit according to the above administrative division is to energize only the water supply valve at the time of water supply administration, to conduct electricity to the main motor at the fully automatic mechanical timer at the time of washing or rinsing administration, and to the solenoid at the time of drainage administration. The main motor and solenoid are energized to open the drain valve and to rotate the washing tank at the time of dehydration.

즉, 배수 및 탈수행정시에는 배수밸브가 개방되어야 하며, 특히 탈수행정시에는 동시에 주모타를 회전시켜 세탁조를 회전시켜야 한다.In other words, the drain valve should be opened during drainage and dehydration stroke, and in particular, during the dehydration stroke, the main motor should be rotated to rotate the washing tank.

종래의 전자동 기계식 세탁기는 제1도에 도시된 것과 같은 전기회로를 이용하여 배수행정시는 전자동 기계식 타이머(1)에서 솔레노이드(2)에 통전시키고, 탈수행정시에는 솔레노이드(2)와 주모타(3)에 통전시키도록 되어 있다.The conventional fully automatic mechanical washing machine uses an electric circuit as shown in FIG. 1 to energize the solenoid (2) in the fully automatic mechanical timer (1) during the drainage stroke, and the solenoid (2) and the main motor (in dehydration stroke). 3) to be energized.

종래의 전자동 기계식 세탁기의 배수장치의 기계적 구성은 제2도에서 알 수 있는 바와 같이, 배수통로(4) 상에 배수 밸브(5)가 설치되어 있으며, 배수밸브(5)를 개방시키기 위하여 솔레노이드(2)가 구성되어 있다. 배수밸브(5)의 밸브로드(6)와 솔레노이드(2)의 작용로드(7) 사이에는 밸브연결판(8)이 설치되어 있어서 솔레노이드(2)에 통전되면 솔레노이드(2)의 작용로드(7)의 견인력에 의해서 배수밸브(5)가 개방되며, 솔레노이드(2)에 통전상태를 해제하면 밸브하우징(9) 안에 내장된 밸브스프링(10) 및 솔레노이드(2) 안에 내장된 복귀스프링의 복원력에 의해서 배수밸브(5)가 폐쇄된다.As can be seen in FIG. 2, the mechanical configuration of the drainage apparatus of the conventional fully automatic mechanical washing machine is provided with a drain valve 5 on the drain passage 4, and the solenoid ( 2) is configured. A valve connecting plate 8 is provided between the valve rod 6 of the drain valve 5 and the actuating rod 7 of the solenoid 2 so that when the solenoid 2 is energized, the actuating rod 7 of the solenoid 2 is energized. The drain valve (5) is opened by the traction force, and when the energized state is released from the solenoid (2), the valve spring (10) built in the valve housing (9) and the restoring force of the return spring built in the solenoid (2) The drain valve 5 is closed by this.

한편, 제3도에 약식으로 도시된 기어메카니즘 어셀블리(11)는 세탁 및 헹쿰행정시에는 세탁조 안에 있는 필세이터(12)만을 회전시키고 탈수행정시에는 세탁조(13)를 회전시키도록 구성되어 있는데, 필세이터(12)를 회전시킬 때는 브레이크밴드(4)에 의해서 브레이크드럼(15)을 구속하고 클러치레바(16)에 의해서 클러치보스(17)를 구속하도록 되어 있고, 반대로 세탁조를 회전시킬 때에는 브레이크밴드(14)가 브레이크드럼(15)으로부터 해제되고, 클러치레바(16)가 클러치보스(17)로부터 해제되도록 되어 있다.On the other hand, the gear mechanism assembly 11 shown schematically in FIG. 3 is configured to rotate only the filler 12 in the washing tank during the washing and rinking stroke, and to rotate the washing tank 13 during the dehydrating stroke. The brake drum 15 is restrained by the brake band 4 and the clutch boss 17 is restrained by the clutch lever 16 when rotating the filler 12. On the contrary, the brake is rotated when the washing tank is rotated. The band 14 is released from the brake drum 15 and the clutch lever 16 is released from the clutch boss 17.

상기 구속 및 해제동작을 수행하게 하기 위해서 브레이크레바(18)가 브레이크밸드(14)와 밸브연결관(8) 사이에 힌지(19)를 중심으로 회동가능하게 연결되어 있고, 클러치레바(16)가 브레이크레바(18)의 작용에 따라 힌지(20)를 중심으로 회동가능하게 설치되어 있다.In order to perform the restraint and release operation, the brake lever 18 is rotatably connected about the hinge 19 between the brake belt 14 and the valve connecting pipe 8, and the clutch lever 16 is rotated. According to the action of the brake lever 18, the hinge 20 is rotatably installed.

배수 또는 탈수행정시 솔레노이드(2)에 전기가 통전되어 밸브연결판(8)이 솔레노이드(2)쪽으로 이동하고 배수밸브(5)가 개방되면 브레이크레바(18)가 힌지(19)를 중심으로 반시계 방향으로 회전하여 브레이크밴드(14)를 브레이크드럼(15)으로부터 해제시킴과 동시에 클러치레바(16)를 힌지(20)를 중심으로 반시계 방향으로 회전시켜 클러치보스(17)로부터 해제시키게 된다.When the drainage or dehydration stroke is energized by the solenoid (2), the valve connecting plate (8) moves toward the solenoid (2) and when the drain valve (5) is open, the brake lever (18) is half-centered around the hinge (19) By rotating clockwise to release the brake band 14 from the brake drum 15, the clutch lever 16 is rotated counterclockwise about the hinge 20 to be released from the clutch boss 17.

따라서 탈수행정시 배수밸브(5)가 개방됨과 동시에 주모타의 회전력에 의해서 세탁조가 회전하게 되는 것이다.Therefore, when the drainage valve 5 is opened during the dehydration stroke, the washing tank is rotated by the rotational force of the main motor.

상기와 같은 종래의 전자동 기계식 세탁기에 있어서 배수장치의 문제점은 배수 및 탈수행정시 솔레노이드(2)가 급속하게 작동하는 것에 의해서 배수밸브(5)의 개폐시 솔레노이드(2)와 배수밸브(5)에서 딱하는 충격음이 발생하는 것이다. 딱하는 소음은 매우 커서 사람을 놀라게 할 뿐만 아니라 세탁기의 품위도 떨어뜨리는 것이다.The problem of the drainage device in the conventional fully automatic mechanical washing machine is that the solenoid (2) in the operation of the drainage and dewatering operation is rapidly operated in the solenoid (2) and the drainage valve (5) when opening and closing the drain valve (5) The sound of shock is generated. The noise is so loud that it not only scares people, but also degrades the washing machine.

[발명의 목적][Purpose of invention]

본 발명의 목적은 상기 문제점을 해결하기 위한 것으로서 배수 및 탈수행정의 시작과 종료시에 배수밸브에서 발생하는 충격음을 제거하도록 된 배수장치를 갖는 무충격 전자동 기계식 세탁기를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a shock-free fully automatic mechanical washing machine having a drainage device for removing the impact sound generated at the drain valve at the start and end of the drainage and dehydration stroke.

본 발명의 다른 목적은 배수장치를 충격음이 발생하기 않도록 구성함에 불구하고 탈수행정의 초기에 주모타가 구속되거나 클러치보스와 클러치레바 사이에서 소음이 발생되지 않도록 하기 위하여 세탁조를 회전시키기 위한 주모타의 작동을 브레이크밴드와 클러치레바가 완전히 해제될 때까지 지연시키도록 된 제어회로가 구비된 무충격 전자동 기계식 세탁기를 제공하는데 있다.Another object of the present invention is to control the main motor for rotating the washing tank so that the main motor is not restrained or noise is generated between the clutch boss and the clutch lever at the beginning of the dehydration stroke, even though the drainage device is configured not to generate an impact sound. An impact-free fully automatic mechanical washer is provided with a control circuit adapted to delay operation until the brakeband and clutch lever are fully released.

[발명의 요약][Summary of invention]

본 발명은 상기 목적을 달성하기 위하여 배수장치의 배수밸브를 개폐시키는 수단으로서 솔레노이드 대신에 동기모타를 채택하여 배수밸브를 천천히 개폐시키도록 된 배수장치가 구성되어 있고, 탈수행정시 배수밸브가 완전히 개방되고 브레이크밴드가 브레이크드럼에서 완전히 해제되며 클러치레바가 클러치보스로부터 완전히 해제될때까지 주모타의 작동을 지연시키기 위한 수단이 구비되어 있는 것을 특징으로 한다.The present invention is a means for opening and closing the drain valve of the drainage device in order to achieve the above object is a drainage device is configured to open and close the drainage valve slowly by adopting a synchronous motor instead of the solenoid, the drainage valve is fully open during dehydration administration And a means for delaying the operation of the main motor until the brake band is completely released from the brake drum and the clutch lever is completely released from the clutch boss.

본 발명은 브레이크밴드과 클러치레바가 완전히 해제될때까지 주모타의 작동을 지연시키기 위하여 동기모타에 전기가 통전될 때에만 차단되는 NC타입의 릴레이와 NO타입의 제어스위치가 주모타에 병렬로 연결되어 탈수행정 초기에 릴레이를 차단시키고 브레이크밴드와 클러치레바가 완전히 해제된 후에 제어스위치를 온(ON)시켜주어 주모타가 작동되도록 주모타 및 동기모타의 제어회로가 구성된 것을 특징으로 하고 있다.In the present invention, the NC type relay and the NO type control switch, which are cut off only when the synchronous motor is energized to delay the operation of the main motor until the brake band and the clutch lever are completely released, are connected in parallel to the main motor and dewatered. The control circuit of the main motor and the synchronous motor is configured to operate the main motor by shutting off the relay at the beginning of the stroke and turning on the control switch after the brake band and the clutch lever are completely released.

[발명의 구체예에 대한 설명][Description of Specific Example of the Invention]

이하 본 발명의 첨부도면을 참조하여 자세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

제4도에 도시되어 있는 바와 같이 배수밸브(5)를 개폐시켜주는 수단으로서 종래의 솔레노이드(2) 대신에 동기모타(21)가 설치되어 있으며 동기모타(21)의 와이어(22)가 밸브연결관(8)에 연결되어 있다.As shown in FIG. 4, as a means for opening and closing the drain valve 5, a synchronous motor 21 is provided in place of the conventional solenoid 2, and the wire 22 of the synchronous motor 21 is connected to the valve. It is connected to the tube (8).

동기모타(21)는 낮은 회전속도로 회전시킬 수 있는 것이다. 따라서 동기모타(21)에 전기가 통전되면 동기모타(21)가 천천히 회전하여 와이어(22)를 천천히 감음으로써 밸브연결판(8)을 동기모타(21)쪽으로 당기게 되고 그에 따라 배수밸브(5)를 개방시키게 된다. 즉 종래와 같이 솔레노이드(2)에 의해서 급속하게 배수밸브(5)를 개방시키는 것이 아니라 5~7초의 시간에 걸쳐서 배수밸브(5)를 개방하도록 되어 있다.Synchronous motor 21 can be rotated at a low rotational speed. Therefore, when electricity is supplied to the synchronous motor 21, the synchronous motor 21 rotates slowly to slowly wind the wire 22 to pull the valve connecting plate 8 toward the synchronous motor 21, and accordingly the drain valve 5 Will open. In other words, instead of opening the drain valve 5 rapidly by the solenoid 2, the drain valve 5 is opened over a period of 5 to 7 seconds.

배수밸브(5)가 개방되는 동안 밸브연결판(8)에 설치된 브레이크작동볼트(23)의 작용력에 의해서 브레이크레바(18)라 힌지(19)를 중심으로 반시계방향으로 회동하여 브레이크밸브(14)를 브레이크드럼(15)으로부터 해제하고, 또한 브레이크레바(18)의 반시계방향의 회전력에 의해서 클러치레바(16)가 힌지(20)를 중심으로 반시계 방향으로 회동하여 클러치보스(17)로부터 해제된다.While the drain valve 5 is opened, the brake valve 14 rotates counterclockwise around the hinge 19 called the brake lever 18 by the action of the brake actuating bolt 23 provided on the valve connecting plate 8. ) Is released from the brake drum 15, and the clutch lever 16 is rotated counterclockwise about the hinge 20 by the counterclockwise rotational force of the brake lever 18 to release the clutch boss 17 from the clutch boss 17. Is released.

브레이크밴드(14)와 클러치레바(16)가 각 브레이크드럼(15)과 클러치보스(17)로부터 해제되면 기어메카니즘 어셈블리(11)가 세탁조를 회전시킬 수 있는 상태가 되는 것은 이미 잘 알려진 사실이다.It is well known that the brake mechanism 14 and the clutch lever 16 are released from the brake drum 15 and the clutch boss 17 so that the gear mechanism assembly 11 can rotate the washing tub.

동기모타(21)에 전류가 차단되면 밸브하우징(9)에 내장된 밸브스피링(10)과 힌지(19)에 각각 설치된 힌지 스프링의 복원력에 의해서 배수밸브(5)가 천천히 폐쇄되고 브레이크밴드(14)가 브레이크드럼(15)을 구속하게 되고 클러치레바(16)가 클러치보스(17)를 구속하게 된다.When the current is interrupted in the synchronous motor 21, the drain valve 5 is slowly closed by the restoring force of the hinge spring installed in the valve spring 10 and the hinge 19, respectively, which are built in the valve housing 9, and the brake band ( 14 restrains the brake drum 15 and the clutch lever 16 restrains the clutch boss 17.

전술한 바와 같이, 본 발명은 배수밸브(5)의 개폐수단으로서 동기모타(22)가 구성되어 있기 때문에 배수 및 탈수행정의 시작과 종료시에 배수장치에서 충격음이 발생하지 않게 된다.As described above, in the present invention, since the synchronous motor 22 is configured as the opening and closing means of the drain valve 5, the impact sound is not generated in the drainage device at the start and end of the drain and dewatering stroke.

그러나 주모타제어회로를 종래와 같은 제어회로를 그대로 채용한다고 하면 다음과 같은 새로운 문제점이 발생한다.However, if the main motor control circuit employs the same control circuit as before, the following new problems occur.

종래의 주모타제어회로는 솔레노이드(2)에 통전됨과 동시에 주모타(3)에도 전원이 인가되도록 되어 있다. 그런데 본 발명의 배수장치는 동기모타(21)가 천천히 회전하여 배수밸브(5)를 천천히 개방하고, 브레이크밴드(4)를 브레이크드럼(15)으로부터 천천히 해제하며, 클러치레바(16)를 클러치보스(17)로부터 서서히 해제하도록 되어 있어서 탈수행정시 초기에는 기어메카니즘 어셈블리(11)가 세탁조(13)를 회전시킬 수 있는 상태가 되지 않는다. 이 상태에서 주모타(3)에 전원이 인가되면 주모타(3)가 구속되어 소손도거나 클러치레바(16)과 클러치보스(17) 사이에서 소음이 발생하게 된다.In the conventional main motor control circuit, the solenoid 2 is energized and the main motor 3 is also supplied with power. However, in the drainage device of the present invention, the synchronous motor 21 rotates slowly to slowly open the drain valve 5, the brake band 4 is slowly released from the brake drum 15, and the clutch lever 16 is the clutch boss. The gear mechanism assembly 11 is not in a state capable of rotating the washing tub 13 at the initial stage during the dehydration stroke because it is to be released gradually from 17. When power is applied to the main motor (3) in this state, the main motor (3) is restrained and noise is generated between the clutch lever (16) and the clutch boss (17).

따라서 배수장치의 구성의 변경에 따라 주모타 및 동기모타의 제어회로도 변경시킬 필요가 있다. 즉 브레이크밴드(14)가 브레이크드럼(15)으로부터 완전히 해제되고 클러치레바(16)가 클러치보스(17)로부터 완전히 해제될때까지 주모타(3)의 작동을 지연시킬 필요가 있다.Therefore, it is necessary to change the control circuits of the main motor and the synchronous motor as the configuration of the drainage device changes. That is, it is necessary to delay the operation of the main motor 3 until the brake band 14 is completely released from the brake drum 15 and the clutch lever 16 is completely released from the clutch boss 17.

본 발명은 브레이크밸브(14)와 클러치레바(16)의 완저해제시까지 주모타(3)의 작동을 지연시키기 위하여 제5도에 도시되어 있는 바와 같이 릴레이(24)와 제어스위치(25)가 주모타(3)에 병렬로 연결되어 있다.The present invention provides a relay 24 and a control switch 25 as shown in FIG. 5 to delay the operation of the main motor 3 until the brake valve 14 and the clutch lever 16 are released. It is connected in parallel with the main motor (3).
