본 발명은 냉장고의 도어로킹장치에 관한 것이다.The present invention relates to a door locking device of a refrigerator.

냉장고의 도어는 일반적으로 본체의 일측면에 힌지결합되어 힌지를 축으로 본체에 대해 상대 회동함으로써 개폐되며, 도어와 본체간의 전체둘레의 접촉면에는 영구자석이 내장된 가스켓이 마련되어 이들을 상호 밀착시킴으로써 내장실의 기밀을 유지한다.The door of the refrigerator is generally hinged to one side of the main body, and is opened and closed by rotating the hinge relative to the main body about the axis, and a gasket with permanent magnets is provided on the contact surface of the entire circumference between the door and the main body to closely adhere them to each other. To keep it confidential.

이러한 종래의 냉장고에서는 도어가 가스켓 상호간의 자력에 의해 밀착되어 있기 때문에, 도어를 개방하기 위해서는 가스켓간의 접촉자력을 능가하는 개방력이 필요하므로, 사용자들은 도어를 여는데 상당한 힘겨움을 느끼게 된다.In such a conventional refrigerator, since the doors are in close contact with each other by the magnetic force between the gaskets, in order to open the doors, an opening force that exceeds the contact magnetic force between the gaskets is required, and users feel considerable difficulty in opening the door.

또한, 시간이 흐름에 따라 영구자석의 자력이 약화되고, 이에 따라 냉장고본체와 도어 사이의 접촉면이 균일하게 밀착되지 못하여 틈새가 형성되며, 이들 사이로 냉장실 내부의 냉기가 누출되어, 냉장고의 효율이 저하하게 된다.In addition, as time passes, the magnetic force of the permanent magnet is weakened. As a result, the contact surface between the refrigerator main body and the door is not uniformly contacted, and a gap is formed. Between these, cold air inside the refrigerating compartment leaks, and the efficiency of the refrigerator decreases. Done.

따라서, 본 발명의 목적은, 종래의 문제점을 고려하여, 영구자석의 사용을 배제함으로써, 도어를 여는데 힘이 적게 들고, 자력의 약화로 인한 냉기의 누출등이 발생하지 않는 도어의 로킹장치를 제공하는 것이다.Accordingly, an object of the present invention, in consideration of the conventional problems, by eliminating the use of permanent magnets, the locking device of the door is less power to open the door, the leakage of cold air due to the weak magnetic force does not occur. To provide.

제1도는 본 발명에 따른 도어로킹장치를 구비한 냉장고의 내장실의 도어의 개방상태의 사시도이다. 본 냉장고는 상측에 냉동실과 하측에 냉장실이 각각 형성되고 있고, 냉장실의 전면개구를 개폐하는 도어(2)가 일측연부의 상단과 하단에 각각 마련된 힌지(4)에 의해 회동가능하게 지지되어 있으며, 힌지(4)는 냉장고본체(1)에 고정된 브래킷(5)에 지지되어 있다.1 is a perspective view of an open state of a door of a built-in chamber of a refrigerator equipped with a door locking device according to the present invention. The refrigerator is provided with a freezer compartment at the upper side and a refrigerating compartment at the lower side, and a door 2 for opening and closing the front opening of the refrigerating compartment is rotatably supported by a hinge 4 provided at the upper and lower ends of one side edge, respectively. The hinge 4 is supported by the bracket 5 fixed to the refrigerator main body 1.

냉장고본체(1)와 도어(2)의 상호접촉면에는 도어(2)의 폐쇄시 냉기의 유출을 방지하기 위한 가스켓(3a,3b)이 각각 대응하도록 설치되어 있고, 이들 가스켓(3a,3b)에는 종래와 같은 접촉유지용 영구자석이 내장되어 있지 아니하다. 도어(2)에는 도어(2)의 개방시 사용자가 잡아당길 수 있는 해제손잡이(13)가 설치되어 있다.On the mutual contact surface of the refrigerator main body 1 and the door 2, gaskets 3a and 3b for preventing the outflow of cold air when the door 2 is closed are respectively provided so as to correspond to the gaskets 3a and 3b. There is no built-in permanent magnet for contact holding as in the prior art. The door 2 is provided with a release knob 13 that can be pulled by the user when the door 2 is opened.

또한, 냉장고본체(1)의 좌측벽연부영역에는 도어(2)를 향하여 걸림턱(7a,7b)이 상하에 각 하나씩 형성되어 있고, 이에 대응하여 도어(2)측에는 걸림턱(7a,7b)에 맞물림 수 있는 후크부재(15a,15b)가 설치되어 있다.In addition, in the left wall edge region of the refrigerator main body 1, the locking jaws 7a and 7b are formed in the upper and lower sides toward the door 2, and correspondingly, the locking jaws 7a and 7b are provided on the door 2 side. The hook members 15a and 15b which can be engaged with are provided.

제2도는 냉장고의 측단면도이고, 제3도는 제2도의 도어의 개방상태의 측단면도이다. 이들 도면에서 볼 수 있는 바와 같이, 회동핀(17)에 의해 회동가능하게 설치된 해제손잡이(13)의 도어(2)내부측 단부에는 막대상의 링크(12)가 링크핀(19a)에 의해 상대회동 가능하게 연결되어 하향연장되어 있으며, 이 링크(12)는 가이드(11)에 의해 상하이동가능하도록 안내된다. 링크(12)에 형성된 플랜지부(16)와 가이드(11)사이에는 압축코일스프링(14)이 개재되어 링크(12)를 하향 탄성부세한다.2 is a side cross-sectional view of the refrigerator, and FIG. 3 is a side cross-sectional view of the open state of the door of FIG. As can be seen in these figures, at the inner end of the door 2 of the release knob 13 rotatably provided by the pivot pin 17, a link 12 on the rod is rotated relative by the link pin 19a. It is possibly connected and extended downward, and this link 12 is guided to be movable by the guide 11. A compression coil spring 14 is interposed between the flange 16 and the guide 11 formed in the link 12 to bias the link 12 downwardly.

링크(12)의 상측과 하측에는, 각기 소회동핀(18a,18b)에 의해 회동가능하게 설치된 후크부재(15a,15b)의 단부가 링크핀(19b,19c)에 의해 링크(12)에 연결되어 있고, 본체(1)를 향한 후크부재(15a,15b)의 자유단에는 걸림부(20a,20b)가 형성되어 있다. 걸림부(20a,20b)는 이에 대응하여 마련된 냉장고본체(1)의 걸림턱(7a,7b)에 걸림 또는 걸림해제가 가능하다. 후크부재(15a,15b)는 링크(12)를 상시 하향부세하는 스프링(14)에 의해 그 걸림부(20a,20b)가 하향 걸림턱(7a,7b)에 걸리는 방향으로 탄성부세되고 있다.On the upper side and the lower side of the link 12, end portions of the hook members 15a and 15b rotatably installed by the small pivot pins 18a and 18b are connected to the link 12 by the link pins 19b and 19c, respectively. At the free ends of the hook members 15a, 15b facing the main body 1, locking portions 20a, 20b are formed. The catching portions 20a and 20b may be caught or released from the catching jaws 7a and 7b of the refrigerator body 1 provided correspondingly. The hook members 15a and 15b are elastically biased in a direction in which the locking portions 20a and 20b are engaged with the downward locking jaws 7a and 7b by the springs 14 which always bias the link 12 downwardly.

이와 같은 구성에 의하여, 도어를 개방하려 할 경우, 사용자가 해제손잡이를(13)를 당기면 링크(12)는 압축코일스프링(14)의 하향탄성력을 대항하여 상향이동하게 되고, 이 링크(12)에 연결된 후크부재(15a,15b)는 회동핀(18a,18b)을 축으로 회동하게 된다. 이에 의해 후크부재(15a,15b)의 걸림부(20a,20b)는 냉장고본체(1)의 걸림턱(7a,7b)으로부터 이탈하게 된다. 따라서 적은 힘으로도 도어(2)는 개방되게 한다.By such a configuration, when the user wants to open the door, when the user pulls the release knob 13, the link 12 moves upward against the downward elastic force of the compression coil spring 14, and the link 12 Hook members (15a, 15b) connected to the pivot pin (18a, 18b) to rotate. As a result, the locking portions 20a and 20b of the hook members 15a and 15b are separated from the locking jaws 7a and 7b of the refrigerator body 1. Thus, the door 2 is opened with a small force.

한편, 도어(2)를 폐쇄하려 할 경우, 도어(2)가 본체(1)에 접근하면 후크부재(15a,15b)의 걸림부(20a,20b)에 형성되어 있는 경사면이 걸림턱(7a,7b)에 접촉하면서 후크부재(15a,15b)는 회동핀(18a,18b)을 중심으로 회동되며, 이어서 링크(12)를 하향부세하는 스프링(14)의 작용에 의해 걸림부(20a,20b)는 탄성적으로 걸림턱(7a,7b)에 걸리게 된다.On the other hand, when the door 2 is to be closed, when the door 2 approaches the main body 1, the inclined surfaces formed on the locking portions 20a and 20b of the hook members 15a and 15b are caught by the locking jaw 7a, The hook members 15a and 15b are rotated about the pivot pins 18a and 18b while being in contact with 7b), and then the locking portions 20a and 20b are caused by the action of the spring 14 which downwardly biases the link 12. Is elastically caught by the locking step (7a, 7b).

이상 설명한 바와 같이, 본 발명에 따르면, 영구자석의 사용을 배제하여 도어를 여는데 힘이 적게 들고, 자력의 약화로 인한 냉기의 누출등이 발생하지 않는 도어의 로킹장치가 제공되게 한다.As described above, according to the present invention, it is possible to provide a locking device for a door which eliminates the use of permanent magnets, and has less power to open the door, and does not cause leakage of cold air due to weakening of magnetic force.
