본 발명은 냉장고의 도어를 잠그거나 해제시키는 냉장고의 도어잠금장치에 관한 것으로서, 보다 상세하게는 필요시 도어를 잠금 및 해제시켜 개폐할 수 있고, 또한 잠금수단이 로킹되지 않도록 하여 사용이 매우 편리하도록 된 냉장고의 도어 잠금장치에 관한 것이다.The present invention relates to a door lock device of a refrigerator for locking or releasing a door of a refrigerator. More particularly, the present invention relates to a door lock device of a refrigerator, which can be opened and closed by locking and releasing the door if necessary, and also to prevent the locking means from being locked. It relates to a door lock of the refrigerator.

일반적으로 냉장고는 제1도에 도시한 바와 같이 본체(1)의 전면에 다수의 도어(2)(3)가 개폐가능하게 결합되어 있으며, 고내의 내용물을 인출할 경우에는 상기 도어(2)(3)를 당겨서 개방시킨 상태에서 내용물을 인출하게 된다.In general, a refrigerator has a plurality of doors (2) (3) coupled to the front of the main body (1) so as to be openable and open, as shown in FIG. 1, and the door (2) ( 3) Pull out the contents while opening the contents.

그러나, 이와 같은 종래의 냉장고는 어린이 등이 빈번히 도어를 개폐시킴에 따라 냉기의 유출이 심할 뿐만 아니라 소비전력이 증대되는 문제점이 있다.However, such a conventional refrigerator has a problem in that as the children frequently open and close the door, cold air is not only severely leaked but power consumption is increased.

또한, 근래에는 냉장고가 대형화됨에 따라 부주의로 유아등이 고내에 출입을 하여 질식되는 안전상의 문제점도 내재되어 있다.In addition, in recent years, as the refrigerator is enlarged, there are also inherent safety problems that children inadvertently enter and exit the interior of the refrigerator.

본 발명은 이와 같은 종래 기술의 문제점들을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 선택적으로 도어를 잠금 및 해제 시킬 수 있도록 하여 어린이 등이 불필요하게 도어를 개폐작동시키지 않도록 하여 냉기의 유출을 방지함과 동시에 소비전력을 절약할 수 있는 냉장고의 도어 잠금장치를 제공하는데 있다.The present invention has been invented to solve the problems of the prior art, the object of the present invention is to selectively lock and unlock the door to prevent children from opening and closing the door unnecessarily to prevent the leakage of cold air At the same time to provide a door lock of the refrigerator that can save power consumption.

또한, 본 발명의 다른 목적은 도어의 잠금 및 해제작동이 선택적으로 이루어지도록 하여 사용이 매우 편리하고 유아나 어린이 등의 안전사고를 미연에 방지할 수 있는 냉장고의 도어 잠금장치를 제공하는데 있다.In addition, another object of the present invention is to provide a door lock device for a refrigerator that can be selectively used to lock and unlock the door is very convenient to use and prevent accidents such as infants and children.

이와 같은 목적을 실현하기 위하여 이루어진 본 발명에 의한 냉장고의 도어잠금장치를 냉장고 본체와, 상기 냉장고의 본체에 개폐가능하게 결합된 도어를 포함하는 냉장고에 있어서, 상기 도어에는 폐쇄시에 잠금상태가 유지되는 도어잠금수단이 구비된 것을 특징으로 한다.In the refrigerator comprising a door lock device of the refrigerator according to the present invention made to achieve the above object and a door coupled to the main body of the refrigerator so as to be openable and closed, the door is locked when the door is closed. Characterized in that the door locking means is provided.

따라서, 유아나 어린이들에 의해 불필요하게 도어가 개방되지 않도록 하여 냉기의 유출을 방지함과 동시에 소비전력을 현저하게 절감할 수 있게 된다.Therefore, the door is not unnecessarily opened by the infants or children, thereby preventing the leakage of cold air and at the same time significantly reducing the power consumption.

이하, 본 발명의 바람직한 실시예를 첨부된 도면 제2도 내지 제5도를 참조하여 더욱 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to FIGS. 2 to 5.

도면에서 부호(10)은 도어(3)의 일측에 장착되어 폐쇄시에는 로킹상태가 유지되는 도어잠금수단을 나타내고 있다.In the drawing, reference numeral 10 denotes a door locking means mounted on one side of the door 3 to maintain the locked state when the door 3 is closed.

상기 도어잠금수단(10)은 조작에 따라 소정의 각도로 회동되는 회동부재(12)와, 상기 회동부재(12)의 작동에 따라 선택적으로 본체(1)내에 형성된 걸림홈(1a)내에 삽입 및 이탈되는 로크부재(14)를 포함한다.The door locking means (10) is inserted into the locking member (12) rotated at a predetermined angle in accordance with the operation, and the engaging groove (1a) formed in the main body 1 selectively in accordance with the operation of the rotating member (12) And a lock member 14 that is separated.

그리고, 상기 회동부재(12)는 힌지축(16)에 의해 힌지결합되어 있으며, 그 일단은 스프링(18)에 의해 탄발설치되어 있다.The rotation member 12 is hinged by a hinge shaft 16, one end of which is installed by a spring 18.

또한, 상기 로크부재(14)는 회동부재(12)의 작동에 따라 회동되도록 힌지축(16a)에 의해 힌지결합되어 있고, 그 일단에는 상기 걸림홈(1a)내에 삽입 및 이탈되는 걸림부(14a)를 형성하고 있으며, 그 하단은 스프링(18a)에 의해 탄발설치되어 있다.In addition, the lock member 14 is hinged by the hinge shaft 16a to be rotated according to the operation of the rotation member 12, one end of the locking portion 14a that is inserted into and removed from the locking groove (1a). Is formed, and the lower end is provided with a spring and a spring by the spring 18a.

한편, 상기 로크부재(14)의 상측에는 도어잠금수단(10)의 작동을 수단에 따라 선택할 수 있는 잠금선택수단(20)이 설치되어 있다.On the other hand, on the upper side of the lock member 14 is provided with a lock selecting means 20 that can select the operation of the door locking means 10 according to the means.

상기 잠금선택수단(20)은 제4도에 도시한 바와 같이 도어(3)내에 형성된 안내홈(3a)내에서 슬라이드 작동되어 선택적으로 상기 로크부재(14)의 회동작동을 제어하는 슬라이드부재(22)와 상기 슬라이드부재(22)의 상승 및 하강위치를 유지시키는 스토퍼(24a)(24b)를 포함하고 있으며, 상기 슬라이드부재(22)에는 스토퍼(24a)(24b)가 삽입되는 요홈(22a)이 형성되어 있다.As shown in FIG. 4, the lock selecting means 20 slides in the guide groove 3a formed in the door 3 to selectively control the rotational operation of the lock member 14. ) And stoppers 24a and 24b for maintaining the up and down positions of the slide member 22, and the groove 22a into which the stoppers 24a and 24b are inserted is inserted into the slide member 22. Formed.

도명중 부호 26은 도어(3)의 내측에 부착된 가스켓을 나타내고 있다.Reference numeral 26 in the drawing denotes a gasket attached to the inside of the door 3.

다음에 이와 같이 구성된 본 발명에 의한 냉장고의 도어잠금장치에 대한 작용 및 효과를 설명한다.Next, the operation and effect of the door lock device of the refrigerator according to the present invention configured as described above will be described.

먼저, 제4도에 도시한 바와 같이 잠금선택수단(20)을 상승시킨 상태에서는 슬라이드부재(22)가 상승됨으로써 도어잠금수단(10)이 작동 가능한 상태로 된다.First, as shown in FIG. 4, in the state in which the lock selecting means 20 is raised, the slide member 22 is lifted so that the door locking means 10 is operable.

즉, 도어(3)를 닫으면 제2도에 도시한 바와 같이 스프링(18)(18a)의 탄성력에 의해 로크부재(14)의 걸림부(14a)가 본체(1)의 걸림홈(1a)내에 위치됨으로써 유아나 어린이들이 도어(3)를 임의로 개방시킬 수 없게 된다.That is, when the door 3 is closed, as shown in FIG. 2, the locking portion 14a of the lock member 14 is inserted into the locking groove 1a of the main body 1 by the elastic force of the springs 18 and 18a. The position prevents infants or children from arbitrarily opening the door 3.

이때, 비교적 높은위치, 즉 유아나 어린이들이 닿지 않는 곳에 위치된 도어잠금수단(10)을 작동시키면 도어(3)의 잠금상태가 해제된다.At this time, by operating the door locking means 10 located in a relatively high position, that is, where children or children do not reach, the locked state of the door 3 is released.

즉, 회동부재(12)을 당기면 스프링(18)이 인장되면서 힌지축(16)을 중심으로 회동하여 로크부재(14)를 회동시키게 되고, 이에 따라 상기 로크부재(14)가 스프링(18a)을 압축시키면서 회동함으로써 걸림부(14a)가 걸림홈(1a)으로부터 이탈되어 제3도에 도시한 바와 같이 도어(3)의 잠금상태가 해제됨과 동시에 도어(3)의 개방이 가능케 되는 것이다.That is, when the pivot member 12 is pulled, the spring 18 is tensioned and rotated about the hinge shaft 16 to rotate the lock member 14. Accordingly, the lock member 14 rotates the spring 18a. By rotating while compressing, the locking portion 14a is detached from the locking groove 1a, thereby releasing the locked state of the door 3 and opening of the door 3, as shown in FIG.

한편, 상기 잠금선택수단(20)을 해제 상태로 하면, 이때에는 슬라이드부재(22)가 하강함으로써 로크부재(14)의 걸림부(14a)의 제5도에 도시한 바와 같이 걸림홈(1a)으로부터 이탈되어 도어(3)의 폐쇄시에도 도어잠금수단(10)이 작동하지 않게 되는 것이다.On the other hand, when the lock selecting means 20 is released, at this time, the slide member 22 is lowered so that the locking groove 1a as shown in FIG. 5 of the locking portion 14a of the lock member 14 is released. The door locking means 10 does not operate even when the door 3 is closed from the door 3.

이때, 상기 슬라이드부재(22)의 요홈(22a)이 스토퍼(24b)에 밀착되어 정지된 상태를 유지하게 되는 것이다.At this time, the groove 22a of the slide member 22 is in close contact with the stopper 24b to maintain the stopped state.

따라서, 유아나 어린이들이 없는 경우에는 잠금선택수단(20)을 해제시킨 상태에서 사용하면 도어(3)의 개폐가 더욱 용이하게 된다.Therefore, when there are no infants or children, when the lock selecting means 20 is used in a released state, opening and closing of the door 3 becomes easier.

상술한 바와 같이 본 발명에 의한 냉장고의 도어잠금장치에 따르면, 도어의 폐쇄시에는 도어잠금수단의 작동으로 임의적으로 열리지 않는 잠금상태가 유지되어, 유아나 어린이들이 도어를 열수 없게 됨으로써 불필요한 도어의 개방에 다른 냉기의 유출이나 소비전력의 낭비를 방지할 수 있고, 필요에 따라 잠금선택수단을 해제시키면 도어의 개폐작동이 용이하게 이루어짐으로써 사용이 매우 편리하게 되는 등의 여러 가지 이점을 갖는다.As described above, according to the door locking device of the refrigerator according to the present invention, when the door is closed, a locked state that is not opened arbitrarily by the operation of the door locking means is maintained, so that children or children cannot open the door, thereby opening unnecessary doors. It is possible to prevent the leakage of other cold air or power consumption, and if necessary, by releasing the lock selection means has a number of advantages, such as easy to open and close the door is made easy to use.
