[발명의 상세한 설명]Detailed description of the invention
(발명의 분야)(Field of invention)
본 발명은 세탁기도어록킹장치에 관한 것이다. 구체적으로 본 발명은 탈수시 세탁기 사용자가 실수로 세탁기도어를 열고 탈수중인 세탁조에 손을 넣어 손을 다치게되는 사고를 예방하기 위하여 탈수중에는 세탁기도어가 열리지 않도록 잠그는 세탁기도어록킹장치에 관한 것이다.The present invention relates to a washing machine door locking device. Specifically, the present invention relates to a washing machine door lock device that locks the washing machine door so that the washing machine door does not open during dehydration in order to prevent an accident in which the washing machine user accidentally opens the washing machine door and puts his / her hand in the washing tank during dehydration to injure his hand.
(발명의 배경)(Background of invention)
세탁기의 세탁행정이 끝나고 헹굼행정이 끝나면 세탁조의 물을 모두 배수시킨 다음에 세탁조를 고속으로회전시켜 세탁조내의 세탁물에 있는 물기를 원심력에 의해 탈수시키는 탈수행정이 있다.After the washing cycle of the washing machine is finished, the rinsing cycle is finished, and after draining all the water in the washing tank, there is a dehydrating stroke that spins the washing tank at high speed to dehydrate water in the laundry in the washing tank by centrifugal force.
이런 탈수행정시는 세탁조가 고속회전하기 때문에 세탁기 사용자가 실수로 세탁기도어를 열고 손을 세탁조내에 집어넣으면 손에 큰 부상을 입게된다. 그러므로 이런 사고를 방지하려고 종래의 세탁기에는 안전스위치가 붙어있었다. 즉 종래 세탁기에 부착되어 있는 안전스위치는 세탁기도어를 개방시 세탁조하부에 붙어있는 모터에 전원을 차단시켜 탈수를 중단시키는 것이다. 그러나 상기와 같은 종래의 안전스위치는 안전스위치작동이 둔할시 안전사고가 발생할 가능성이 있으며 또한 안전스위치가 적절히 작동해 모터에 전원이 차단되더라도 세탁조의 관성으로 세탁조가 계속 회전중일때 세탁기 사용자가 세탁조에 손을 집어넣으면 안전사고가 발생하는 문제점이 있었다.In this dehydration administration, the washing tank rotates at high speed, so if a washing machine user accidentally opens the washing machine door and inserts his hand into the washing tank, a hand injury is caused. Therefore, in order to prevent such an accident, the conventional washing machine was equipped with a safety switch. That is, the safety switch attached to the conventional washing machine is to stop the dehydration by cutting off the power to the motor attached to the lower part of the washing tank when the washing machine door is opened. However, in the conventional safety switch as described above, there is a possibility that a safety accident may occur when the safety switch operation is dull and the safety switch is properly operated so that even if the power is cut off from the motor, the user of the washing machine may not If you put your hand there was a problem that a safety accident occurs.
(발명의 목적)(Purpose of invention)
본 발명의 목적은 상기 문제점을 해결하기 위하여 세탁기 탈수행정시 세탁기도어를 록킹시킴으로서 세탁기도어가 열리지 못하도록하여 안전사고를 예방하는 세탁기도어록킹장치를 제공하는 것이다.It is an object of the present invention to provide a washing machine door locking device that prevents a safety accident by preventing the washing machine door from opening by locking the washing machine door when the washing machine is dewatered to solve the above problems.
(발명의 요약)(Summary of invention)
본 발명의 세탁기도어록킹장치는 긴 막대형상의 하단부에 스톱퍼가 일체로 형성된 록킹핀, 전자석이 여자되지 않을시 상기 록킹핀을 복귀시키는 스프링, 상기 록킹핀 및 스프링을 내부에 수용하는 록킹핀 하우징으로 구성된 록킹1부재 및 내부에 록킹핀 삽입홈이 형성되고 세탁기 제어마이컴으로부터 신호를 받는 제어단자가 부착된 전자석으로 구성된다.The washing machine door locking device according to the present invention includes a locking pin in which a stopper is integrally formed at a lower end of a long rod, a spring for returning the locking pin when the electromagnet is not excited, and a locking pin housing accommodating the locking pin and the spring therein. The locking 1 member and the locking pin insertion groove are formed therein, and the electromagnet is equipped with a control terminal to receive a signal from the washing machine control microcomputer.
(발명의 구체예에 대한 설명)(Description of Specific Example of the Invention)
이하 본 발명을 첨부한 제1도 및 제2도를 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2.
본 발명의 세탁기도어록킹장치는 내부에 설치된 록킹핀(10)이 록킹삽입홈(22)에 삽입되어 세탁기도어(2)가 열리지 않도록 하는 록킹부재(16), 및 내부에 록킹핀 삽입홈(22)이 형성된 전자석(26)으로 구성된다.The washing machine door locking device according to the present invention includes a locking member 16 to prevent the washing machine door 2 from being opened by the locking pin 10 installed therein and inserted into the locking insertion groove 22, and the locking pin insertion groove 22 therein. Is formed of an electromagnet 26 formed thereon.
록킹부재(16)는 록킹핀(10), 스프링(12) 및 록킹핀 하우징(14)으로 구성된다.The locking member 16 is composed of a locking pin 10, a spring 12 and a locking pin housing 14.
록킹핀(10)은 긴 막대형상이며 하단부에는 윈판형의 스톱퍼(8)가 일체로 형성되어 있고 외주부에는 스프링(12)이 설치되어 있다.The locking pin 10 has a long rod shape, and a stopper 8 having a winpan shape is integrally formed at a lower end thereof, and a spring 12 is installed at an outer circumferential part thereof.
스프링(12)의 중심부는 상기 록킹핀(10)이 관통하며 또한 스프링(12)은 상기 록킹핀(10)의 스톱퍼상부와 록킹핀 하우징(14)의 일측단부내벽 사이에 설치된다.The locking pin 10 penetrates the center of the spring 12, and the spring 12 is installed between the stopper upper portion of the locking pin 10 and an inner wall of one end of the locking pin housing 14.
록킹핀하우징(14)은 내부에 록킹핀(10) 및 스프링(12)을 수용한다.The locking pin housing 14 accommodates the locking pin 10 and the spring 12 therein.
전자석(26)은 세탁기제어부(18)의 제어부밑판(20)에 .고정되며 내부에는 전자석에 의해 흡인되는 록킹핀(10)이 삽입되는 록킹핀삽입홈(22)이 형성되어 있으며 일부분에 압축된 철심(28)이 삽입되어 록킹핀(10)을 끌어당기기에 충분한 자성을 발생한다. 또한 세탁기 제어마이콤으로부터 전기신호를 받아 전자석을 여자 또는 비여자시키는 제어단자(24)가 부착되어 있다.The electromagnet 26 is fixed to the control panel 20 of the washing machine control unit 18. The locking pin insertion groove 22 into which the locking pin 10 is sucked by the electromagnet is inserted therein and is compressed in a part. The iron core 28 is inserted to generate sufficient magnetism to attract the locking pin 10. In addition, a control terminal 24 for exciting or non-exciting the electromagnet is attached to the electric signal from the washing machine control microcomputer.
본 발명의 작용은 다음과 같다.The operation of the present invention is as follows.
세탁기가 탈수중이면 도면에는 미도시되었지만 세탁조에 부착되어 있는 센서가 세탁기의 제어마이컴에 탈수중 신호를 보내면 세탁기제어마이컴을 제어단자(24)에 신호를 보내 전자석(26)을 여자시킨다. 전자석(26)이 여자되면 록킹핀(10)이 전자석(26)쪽으로 흡입되어 록킹핀 삽입홈(22)에 삽입된다. 록킹핀(10)이 전자석(26)의 록킹핀삽입홈(22)에 십입되면 도어손잡이부(4)를 손으로 잡고 세탁기도어(2)를 열려해도 도어(2)가 열리지 않는다.If the washing machine is dewatering, although not shown in the drawing, the sensor attached to the washing tank sends a signal for dehydration to the control microcomputer of the washing machine to send a signal to the control terminal 24 to excite the electromagnet 26. When the electromagnet 26 is excited, the locking pin 10 is sucked toward the electromagnet 26 and inserted into the locking pin insertion groove 22. When the locking pin 10 is inserted into the locking pin insertion groove 22 of the electromagnet 26, the door 2 does not open even when the door handle portion 4 is held by the hand and the washing machine door 2 is opened.
세탁기의 탈수가 다 끝나 세탁조가 회전하지 않으면 세탁조에 부착되어 있는 센서가 세탁기의 제어마이컴에 탈수끝이라는 신호를 보내면 세탁기 제어마이컴은 제어단자(24)에 신호를 보내지 않으며 그 결과로 전자석(26)이 비여자되면 록킹핀(10)은 스프링(12)의 탄성력에 의해 복귀되어 세탁기도어(2)가 자유자재로 열릴수 있다.When the washing machine is dehydrated and the washing tank does not rotate, the sensor attached to the washing machine sends a signal to the control microcomputer of the washing machine that the washing machine is dehydrated. The washing machine control microcomputer does not send a signal to the control terminal 24. As a result, the electromagnet 26 When the non-excitation, the locking pin 10 is returned by the elastic force of the spring 12 so that the washing machine door 2 can be freely opened.
본 발명의 효과는 다음과 같다. 세탁조가 고속회전하며 탈수중일때는 세탁기의 제어마이컴이 전자석(26)에 신호를 보내 록킹핀(10)을 록킹핀 삽입홈(22)으로 흡인시키면 도어손잡이부(4)를 손으로 잡고 세탁기도어(2)를 열려고 해도 열리지 않으므로 고속회전중인 세탁조에 실수로 손이 들어가 안전사고가 발생되는 것을방지할 수 있는 효과가 있다.The effects of the present invention are as follows. When the washing tank rotates at high speed and is dehydrated, the control microcomputer of the washing machine sends a signal to the electromagnet 26 to suck the locking pin 10 into the locking pin insertion groove 22 to hold the door handle 4 and hold the washing machine door ( 2) Because it does not open even if you try to open it, there is an effect that you can prevent accidental accident by entering your hand into the washing tank during high speed rotation.
본 발명은 기재된 구체예에 대해서만 상세히 설명되었지만 본 발명의 사상과 범위내에서 여러가지로 변형 또는 수정할 수 있음은 이 분야의 당업자에게는 명백한 것이며 따라서 그러한 변형 및 수정은 첨부된 특허청구범위에 속하는 것은 당연하다.Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the invention, and such variations and modifications are within the scope of the appended claims.
