냉장고용 도어 힌지{DOOR HINGE FOR REFRIGERATOR}Door hinge for refrigerator {DOOR HINGE FOR REFRIGERATOR}

본 발명은 냉장고용 도어 힌지에 관한 것으로, 특히 도어 힌지 구조를 개선하여 냉장고 도어 개폐작용을 슬라이드 인출식과 힌지 회동식으로 함께 병행할 수 있는 냉장고용 도어 힌지에 관한 것이다.
The present invention relates to a door hinge for a refrigerator, and more particularly, to a door hinge for a refrigerator, which can simultaneously open and close a refrigerator door opening and closing function by a slide pull-out type and a hinge pivot type by improving the door hinge structure.

일반적으로, 냉장고는 냉매가 압축 - 응축 - 팽창 - 증발하는 냉동사이클을 반복함에 따라 냉장실과 냉동실 내부를 저온화시켜 음식물을 일정기간 동안 신선하게 유지시켜 주는 장치이다.In general, a refrigerator is a device that keeps food fresh for a certain period of time by lowering the temperature inside the refrigerating compartment and the freezing compartment as the refrigerant is repeatedly compressed, condensed, expanded, and evaporated.

상기 냉장고는 내부에 음식물을 저온 상태로 보관할 수 있도록 냉동실 및 냉장실이 구비된 냉장고 본체와, 상기 냉장고 본체의 전면을 개폐가능하게 회동시키는 냉장고 도어로 구성된다.The refrigerator includes a refrigerator main body provided with a freezer compartment and a refrigerating compartment to store food in a low temperature state, and a refrigerator door that opens and closes the front of the refrigerator main body so as to be opened and closed.

상기 냉장고 도어를 개폐시키기 위해서는 일단이 상기 냉장고 본체에 고정설치되어 타단이 냉장고 도어에 연결되어 상기 냉장고 도어를 회전가능하게 지지하는 도어 힌지가 설치된다.In order to open and close the refrigerator door, one end is fixedly installed on the refrigerator main body, and the other end is connected to the refrigerator door to install a door hinge rotatably supporting the refrigerator door.

이러한 종래기술에 따른 도어 힌지는 냉장고 도어가 도어 힌지를 축 중심으로 회전하기 때문에, 상기 냉장고 도어의 후벽에 형성된 포켓부 내에 저장된 물품이 도어 힌지쪽 근방에 위치하여 이를 인출하고자 할 경우 상기 냉장고 도어를 냉장고 본체로부터 완전 개방시켜야 하므로 그에 따른 냉기 유출이 심하게 발생하는 문제점이 있었다.
Since the door hinge according to the related art rotates the door hinge about an axis, the article stored in the pocket formed on the rear wall of the refrigerator door is located in the vicinity of the door hinge, and the refrigerator door is opened. Since it must be completely opened from the refrigerator body, there was a problem that the cold air outflow occurs seriously.

FIG. 2 is a plan view illustrating a drawing slide action of the door hinge of FIG. 1. FIG.
Figure 3 is a plan view showing the rotation after withdrawal by the door hinge for the refrigerator according to an embodiment of the present invention.

이하, 첨부된 도 1 내지 도 3을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying Figures 1 to 3 will be described in detail a preferred embodiment of the present invention.

도시한 바와 같이, 본 발명에 따른 냉장고용 도어 힌지는 냉장고 본체(100)의 일측 상단과 하단에 설치되는 제1 힌지축(210)과, 상기 제1 힌지축(210)에 대향하는 냉장고 도어(110)의 일측 상단과 하단에 설치되는 제2 힌지축(220)과, 상기 제1 힌지축(210)과 제2 힌지축(220) 사이를 연결하는 연결부재(230)로 구성된다.As illustrated, the door hinge for a refrigerator according to the present invention may include a first hinge shaft 210 installed at an upper end and a lower end of the refrigerator main body 100 and a refrigerator door facing the first hinge shaft 210. The second hinge shaft 220 is installed on one side upper end and the lower end of the 110, and the connection member 230 for connecting between the first hinge shaft 210 and the second hinge shaft 220.

먼저, 상기 제1 힌지축(210)은 냉장고 본체(100)의 일측 상단과 하단에 설치되는 원통형 구조로 이루어진다.First, the first hinge shaft 210 has a cylindrical structure which is installed on one side top and bottom of the refrigerator body 100.

또한, 상기 제2 힌지축(220)은 상기 제1 힌지축(210)에 대향하는 냉장고 도어(110)의 일측 상단과 하단에 설치된다.In addition, the second hinge shaft 220 is installed at one upper end and the lower end of the refrigerator door 110 facing the first hinge shaft 210.

이러한 상기 제1 힌지축(210)과 제2 힌지축(220)은 각각 상기 냉장고 본체(100)와 냉장고 도어(110)에 대하여 견고하게 고정설치된다.The first hinge shaft 210 and the second hinge shaft 220 are firmly fixed to the refrigerator body 100 and the refrigerator door 110, respectively.

한편, 상기 연결부재(230)는 상기 제1 힌지축(210)과 제2 힌지축(220) 사이를 연결하는 구성이다.On the other hand, the connecting member 230 is a configuration for connecting between the first hinge shaft 210 and the second hinge shaft 220.

여기서, 상기 연결부재(230)는 외력이 작용하는 힘의 방향으로 단계적 슬라이드 인출이 가능한 구조로 이루어진다.Here, the connection member 230 is made of a structure capable of withdrawal step by step in the direction of the force acting external force.

즉, 상기 제1 힌지축(210)과 제2 힌지축(220) 사이를 연결하는 연결부재(230)는 상기 냉장고 도어(110)를 냉장고 본체(100)로부터 직선방향으로 이격시켜 개폐시키는 역할을 수행할 수 있도록 한다.That is, the connection member 230 connecting between the first hinge shaft 210 and the second hinge shaft 220 serves to open and close the refrigerator door 110 in a straight direction away from the refrigerator body 100. Make it work.

이를 위해, 상기 연결부재(230)는, 상기 제1 힌지축(210)에 연결되며 내부에 결합용 중공이 형성된 제1 연결부(231)와, 상기 제1 연결부(231)의 결합용 중공으로부터 인출되는 제2 연결부(232)와, 상기 제2 힌지축(220)에 연결되며 상기 제2 연결부(232)의 결합용 중공으로부터 인출되는 제3 연결부(233)로 구성된다.To this end, the connecting member 230 is connected to the first hinge shaft 210, the first connecting portion 231 and the coupling hollow is formed therein, withdrawal from the coupling hollow of the first connecting portion 231 And a third connection portion 232 connected to the second hinge shaft 220 and drawn out from the coupling hollow of the second connection portion 232.

즉, 상기 제1 연결부(231), 제2 연결부(232), 제3 연결부(233)는 순차적으로 직경의 크기가 작아지는 구조로 형성하여 단계적 슬라이드 인출이 가능하다.That is, the first connecting portion 231, the second connecting portion 232, and the third connecting portion 233 may be formed in a structure in which the size of the diameter decreases in sequence so that the slide out may be stepped out.

이러한 상기 슬라이드 인출식 구조로 이루어진 연결부재(230)는 상기 냉장고 도어(110)의 후벽에 형성된 포켓부 내에 저장된 물품이 도어 힌지쪽 근방에 위치하여 이를 꺼내고자 할 때, 상기 냉장고 도어(110)를 냉장고 본체(100)로부터 완전 개방하는 방향으로 회전시킬 필요없이 상기 냉장고 도어(110)를 잡아당기는 것만으로 일정 개방공간을 마련할 수 있어 물품을 쉽게 꺼내거나 넣을 수 있을 뿐만 아니라, 냉기 유출이 심하게 낭비되는 것을 방지할 수 있는 효과가 있다.The connection member 230 having the slide pull-out structure has the refrigerator door 110 when the article stored in the pocket formed on the rear wall of the refrigerator door 110 is located near the door hinge side and is taken out. It is possible to provide a certain open space by simply pulling the refrigerator door 110 without rotating the refrigerator body 100 in the direction of opening completely, it is not only easy to take out or put the goods, but also bad waste of cold air waste There is an effect that can be prevented.

그리고, 상기 냉장고 도어(110)의 일측에는 밀거나 당기는 방향으로 상기 냉장고 도어(110)를 개폐시킬 수 있도록 인출형 개폐손잡이(111)를 추가적으로 형성하는 것이 바람직하다.In addition, it is preferable to further form a pull-out opening / closing handle 111 on one side of the refrigerator door 110 to open and close the refrigerator door 110 in a pushing or pulling direction.

물론, 상기 연결부재(230)는 상기 냉장고 도어(110)의 이동방향에 따라 직선이동 후 좌,우바향으로 선회 회동이 가능하다.
Of course, the connection member 230 can be rotated in a left and right direction after the linear movement according to the movement direction of the refrigerator door 110.

이와 같이 본 발명에 따르면, 상기 제1 힌지축(210)과 제2 힌지축(220) 사이를 연결하는 연결부재(230)가 외력이 작용하는 힘의 방향으로 단계적 슬라이드 인출이 가능한 구조로 이루어짐에 따라, 도어 힌지쪽에 저장된 물품을 인출시 냉장고 도어(110)를 잡아당기는 것만으로 일정 개방공간을 마련할 수 있어 물품을 쉽게 꺼내거나 넣을 수 있을 뿐만 아니라, 냉기 유출이 심하게 낭비되는 것을 방지할 수 있는 효과가 있다.
Thus, according to the present invention, the connecting member 230 for connecting between the first hinge shaft 210 and the second hinge shaft 220 is made of a structure that can be pulled out step by step in the direction of the force acting external force Accordingly, when pulling out the article stored in the door hinge side, it is possible to provide a certain open space by simply pulling the refrigerator door 110, which can easily take out or put the article, and prevent the cold air from being excessively wasted. It works.
