본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 도어의 개폐에 따른 소음을 방지할 수 있고 도어 축결합공 부분의 변형을 방지할 수 있도록 한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of preventing noise due to opening and closing of a door and preventing deformation of the door shaft coupling hole portion.

통상적인 냉장고의 도어는 저장실의 전면을 개폐할 수 있도록 일측 상부와 하부가 본체에 회전 가능하게 결합된다. 이러한 결합을 위해 본체의 일측 상부와 하부에는 힌지축을 갖춘 힌지브래킷이 각각 설치되고, 도어의 상부와 하부에는 힌지축이 진입하여 결합되는 축결합공을 갖춘 보강부재가 설치된다. 이러한 냉장고의 예는 대한민국 공개특허공보 2005-89549호에 개시되어 있다.The door of a conventional refrigerator is rotatably coupled to one side of the top and bottom of the main body to open and close the front of the storage compartment. Hinge brackets having hinge shafts are respectively installed on the upper and lower sides of the main body, and reinforcing members having shaft coupling holes into which the hinge shaft enters and are coupled to the upper and lower portions of the door are installed. An example of such a refrigerator is disclosed in Korean Laid-Open Patent Publication No. 2005-89549.

이러한 형태의 냉장고 중에는 축결합공 내에 수지재질로 된 원통형의 축지지부재가 설치됨으로써 힌지축이 안정적으로 지지되도록 함과 동시에 원활히 회전할 수 있도록 한 것이 있다. 이는 힌지축이 축지지부재의 내부로 진입하여 회전하도록 한 것이다.In the refrigerator of this type, the cylindrical shaft support member made of a resin material is installed in the shaft coupling hole so that the hinge shaft can be stably supported and rotate smoothly. This is for the hinge shaft to enter and rotate inside the shaft support member.

그러나 이러한 냉장고는 도어를 개폐할 때 축지지부재가 도어에 대하여 상대 회전하는 문제(축지지부재가 헛도는 문제)로 인하여 마찰소음이 발생할 수 있었다. 즉 축지지부재는 도어에 고정된 상태에서 도어와 함께 회전해야 하지만, 축지지부재가 헛도는 문제로 인하여 축지지부재와 보강부재의 축결합공 사이에 마찰이 생기면서 소음이 발생할 수 있었다.However, in such a refrigerator, friction noise may occur due to a problem that the shaft support member rotates relative to the door when the door is opened or closed. That is, the shaft support member should be rotated together with the door in the state fixed to the door, but due to the problem that the shaft support member is idle, friction between the shaft support member and the shaft coupling hole of the reinforcing member could generate noise.

또 이러한 냉장고는 축결합공 쪽에 큰 하중이 작용하기 때문에 장기간 사용할 경우 축결합공 부분에 변형이 생길 수 있었다.In addition, since such a refrigerator has a large load on the shaft coupling hole, deformation of the shaft coupling hole may occur when used for a long time.

본 발명은 이러한 문제점들을 해결하기 위한 것으로, 본 발명의 목적은 도어의 개폐에 따른 소음을 방지할 수 있도록 하는 냉장고를 제공하는 것이다.The present invention is to solve these problems, it is an object of the present invention to provide a refrigerator to prevent the noise caused by the opening and closing of the door.

본 발명에 따른 냉장고는 도 1에 도시한 바와 같이, 전면이 개방된 저장실(11)을 갖춘 본체(10), 저장실(11) 전면의 개폐를 위해 본체(10)에 회전 가능하게 결합되는 도어(20), 도어(20)와 본체(10)를 연결하는 상부 힌지장치(30)와 하부 힌지장치(40)를 구비한다.As shown in FIG. 1, the refrigerator according to the present invention includes a main body 10 having a storage compartment 11 having an open front face, and a door rotatably coupled to the main body 10 for opening and closing the front of the storage compartment 11. 20), the upper hinge device 30 and the lower hinge device 40 for connecting the door 20 and the main body 10 is provided.

하부의 힌지장치(40)는 도 2 내지 도 4에 도시한 바와 같이, 본체(10)의 전면에 결합된 힌지브래킷(41), 힌지브래킷(41)에 고정된 힌지축(42), 힌지축(42)의 결합을 위해 도어(20)에 마련된 축결합공(44), 축결합공(44) 주위의 보강을 위해 도어(20)에 장착되는 외측 및 내측보강부재(45,46), 그리고 힌지축(42) 외면을 지지하도록 축결합공(44)에 설치되는 축지지부재(47)를 포함한다.2 to 4, the lower hinge device 40 includes a hinge bracket 41 coupled to the front surface of the main body 10, a hinge shaft 42 fixed to the hinge bracket 41, and a hinge shaft. Shaft coupling hole 44 provided in the door 20 for the coupling of the 42, outer and inner reinforcing members 45 and 46 mounted to the door 20 for reinforcement around the shaft coupling hole 44, and The hinge shaft 42 includes a shaft support member 47 installed in the shaft coupling hole 44 to support the outer surface.

도어(20)는 상단과 하단을 덮는 커버(21)를 구비하고, 축결합공(44)은 커버(21)에 일체로 마련된 축수용부(43)에 형성된다. 즉 축수용부(43)는 힌지축(42) 을 수용할 수 있도록 커버(21)의 내측에 원통형의 캡 형상으로 마련된다. 이러한 축수용부(43)의 외면은 도 4에 도시한 바와 같이, 도어(20)의 내부에 채워지는 단열재(22)에 의해 지지된다.The door 20 has a cover 21 covering the upper end and the lower end, and the axial coupling hole 44 is formed in the bearing portion 43 integrally provided in the cover 21. That is, the bearing portion 43 is provided in a cylindrical cap shape inside the cover 21 so as to accommodate the hinge shaft 42. As shown in FIG. 4, the outer surface of the bearing 43 is supported by a heat insulating material 22 filled in the interior of the door 20.

축지지부재(47)는 도 3과 도 4에 도시한 바와 같이, 원통형으로 마련되고 하단에 플랜지부(47a)를 구비한다. 축지지부재(47)의 외경은 축결합공(44)에 대응하고, 축지지부재(47)의 내경은 힌지축(42)의 외경에 대응한다. 또 이러한 축지지부재(47)는 힌지축(42)이 결합된 후 힌지축(42) 외면과의 마찰을 최소화할 수 있도록 마찰계수가 낮은 수지재질로 마련된다.3 and 4, the shaft support member 47 is provided in a cylindrical shape and has a flange portion 47a at its lower end. The outer diameter of the shaft support member 47 corresponds to the shaft coupling hole 44, and the inner diameter of the shaft support member 47 corresponds to the outer diameter of the hinge shaft 42. In addition, the shaft support member 47 is provided with a resin material having a low friction coefficient so as to minimize the friction with the outer surface of the hinge shaft 42 after the hinge shaft 42 is coupled.

외측보강부재(45)는 평판형태의 금속으로 이루어지고 고정볼트(48)의 체결을 통하여 커버(21)의 외면에 고정된다. 외측보강부재(46)에는 축지지부재(47)의 외면을 지지할 수 있도록 일측에 제1지지공(45a)이 형성된다. 또 외측지지부재(45)의 제1지지공(45a) 반대편에는 커버(21)로부터 외측으로 돌출하는 외측지지돌기(24)에 결합될 수 있도록 제2지지공(45b)이 형성된다. 이는 제2지지공(45b)이 외측지지돌기(24)에 결합된 상태에서 제1지지공(45a)이 축지지부재(47)의 외면을 지지하도록 함으로써 축지지부재(47)를 견고히 지지할 수 있도록 한 것이다. The outer reinforcing member 45 is made of metal in the form of a plate and is fixed to the outer surface of the cover 21 through the fastening of the fixing bolt 48. The outer reinforcing member 46 is formed with a first support hole 45a on one side to support the outer surface of the shaft support member 47. In addition, a second support hole 45b is formed on the opposite side of the first support hole 45a of the outer support member 45 to be coupled to the outer support protrusion 24 protruding outward from the cover 21. This allows the first support hole 45a to support the outer surface of the shaft support member 47 while the second support hole 45b is coupled to the outer support protrusion 24 so as to firmly support the shaft support member 47. I would have to.

외측보강부재(45)가 결합되는 부분의 커버(21)에는 도 4에 도시한 바와 같이, 외측보강부재(45)가 장착된 후 외측보강부재(45)의 외면이 커버(21)의 외면과 동일한 평면을 이룰 수 있도록 외측보강부재(45)를 수용하는 함몰부(23)가 형성된다. 이는 미려한 외관을 제공함과 동시에 외측보강부재(45)가 함몰부(23)에 수용됨으로써 더욱 견고히 고정될 수 있도록 한 것이다. 그리고 외측보강부재(45)에는 도 2에 도시한 바와 같이, 도어(20)의 개방 시 개방범위를 제한할 수 있도록 하방으로 연장된 스토퍼(49)가 마련된다. 이 스토퍼(49)는 도어(20)의 개방 시 본체(10) 쪽 힌지브래킷(41)의 지지턱(41a)에 걸려 지지됨으로써 도어(20)의 최대 개방범위를 한정한다.As shown in FIG. 4, the outer surface of the outer reinforcing member 45 is attached to the outer surface of the cover 21 after the outer reinforcing member 45 is mounted on the cover 21 of the portion to which the outer reinforcing member 45 is coupled. A depression 23 is formed to accommodate the outer reinforcement member 45 to achieve the same plane. This provides a beautiful appearance and at the same time the outer reinforcing member 45 is accommodated in the recess 23 so that it can be more firmly fixed. And the outer reinforcing member 45, as shown in Figure 2, is provided with a stopper 49 extending downward so as to limit the opening range when opening the door 20. The stopper 49 is caught by the supporting jaw 41a of the hinge bracket 41 toward the main body 10 when the door 20 is opened, thereby limiting the maximum opening range of the door 20.

축지지부재(47)는 그 외면과 외측보강부재(45) 사이에 마련되는 걸림장치에 의하여 회전이 제한된다. 이 걸림장치는 도 3에 도시한 바와 같이, 외측보강부재(45)의 제1지지공(45a)과 대응하는 위치의 축지지부재(47) 외면으로부터 돌출하는 걸림돌기(51)와, 이 걸림돌기(51)가 진입하여 걸리도록 외측보강부재(45)의 제1지지공(45a) 쪽에 형성된 걸림홈(52)을 포함한다. 이러한 구성은 도어(20)를 개폐할 때 도어(20)에 대한 축지지부재(47)의 상대회전을 제한함으로써 축지지부재(47)의 회전에 따른 소음발생을 방지할 수 있도록 한 것이다. 즉 축지지부재(47)의 회전을 제한함으로써 수지재질인 축지지부재(47)와 수지재질인 축수용부(43)의 마찰에 의하여 생길 수 있는 마찰소음을 방지한 것이다.The shaft support member 47 is limited in rotation by a locking device provided between the outer surface and the outer reinforcing member 45. As shown in FIG. 3, the locking device includes a locking protrusion 51 projecting from an outer surface of the shaft supporting member 47 at a position corresponding to the first supporting hole 45a of the outer reinforcing member 45, and the locking protrusion. It includes a locking groove 52 formed in the first support hole (45a) side of the outer reinforcing member 45 so that the machine 51 enters and is caught. This configuration is to prevent the generation of noise due to the rotation of the shaft support member 47 by limiting the relative rotation of the shaft support member 47 with respect to the door 20 when opening and closing the door 20. In other words, by limiting the rotation of the shaft support member 47 is to prevent the friction noise generated by the friction between the resin shaft support member 47 and the resin receiving portion 43 of the resin material.

내측보강부재(46)는 도 3과 도 4에 도시한 바와 같이, 커버(21)의 내측에 설치된다. 내측보강부재(46)의 일단에는 축수용부(43) 외면을 감싸는 형태로 지지하는 제1곡면지지부(46a)가 마련되고, 타단에는 커버(21)의 내면으로부터 돌출된 내측지지돌기(25)에 지지될 수 있도록 내측지지돌기(25)의 외면을 감싸는 제2곡면지지부(46b)가 마련된다. 이러한 내측보강부재(46)는 커버(21)의 내면에 밀착된 상태에서 외측보강부재(45)를 고정하는 고정볼트(48)에 의해 고정된다. 즉 외측보강부재(45)가 커버(21)의 외측에 밀착 배치되고 내측보강부재(46)가 커버(21)의 내면에 밀착 배치된 상태에서 고정볼트(48)가 체결됨으로써 상호 견고히 결속된다. 이는 외측보강부재(45)와 내측보강부재(46)가 상호 지지되도록 함으로써 도어(20)의 축결합공(44) 주위가 보강될 수 있도록 한 것이다. 또 내측보강부재(46)의 제1곡면지지부(46a)가 축수용부(43)의 외면을 감싸는 형태로 지지하고, 내측보강부재(46)의 제2곡면지지부(46b)가 내측지지돌기(25)에 지지됨으로써 축수용부(43)가 더욱 견고히 지지될 수 있도록 한 것이다. 이는 도어(20)의 무게에 의하여 축결합공(44) 쪽에 큰 하중이 걸리더라도 이 부분의 변형을 방지할 수 있도록 한 것이다.As shown in FIGS. 3 and 4, the inner reinforcing member 46 is installed inside the cover 21. One end of the inner reinforcing member 46 is provided with a first curved support portion 46a for supporting the outer surface of the shaft receiving portion 43 in a form surrounding the inner reinforcing member 46, and the other end of the inner support protrusion 25 protruding from the inner surface of the cover 21. A second curved support portion 46b is provided to surround the outer surface of the inner support protrusion 25 so as to be supported by the inner support protrusion 25. The inner reinforcing member 46 is fixed by a fixing bolt 48 for fixing the outer reinforcing member 45 in a state in close contact with the inner surface of the cover 21. That is, the outer reinforcing member 45 is tightly disposed on the outside of the cover 21 and the fixing bolt 48 is fastened in a state where the inner reinforcing member 46 is closely disposed on the inner surface of the cover 21, thereby being firmly bound to each other. This allows the outer reinforcing member 45 and the inner reinforcing member 46 to be mutually supported so that the circumference of the shaft coupling hole 44 of the door 20 can be reinforced. In addition, the first curved support portion 46a of the inner reinforcing member 46 supports the outer surface of the bearing 43, and the second curved support portion 46b of the inner reinforcing member 46 is the inner support protrusion ( 25 is to be supported so that the bearing unit 43 is more firmly supported. This is to prevent deformation of this part even if a large load is applied to the shaft coupling hole 44 by the weight of the door 20.

도어(20)의 상부를 본체(10)에 연결하는 상부의 힌지장치(30)는 도 1에 도시한 바와 같이, 스토퍼 없다는 점과 상부 힌지브래킷(31)이 본체(10)의 상면에 고정되는 점에서 하부 힌지장치(40)와 차이가 있을 뿐 나머지가 하부의 힌지장치(40)와 실질적으로 동일하므로 이에 대한 설명은 생략하기로 한다.As shown in FIG. 1, the upper hinge device 30 connecting the upper portion of the door 20 to the main body 10 has no stopper and the upper hinge bracket 31 is fixed to the upper surface of the main body 10. Since there is a difference from the lower hinge device 40 in that respect, and the rest is substantially the same as the lower hinge device 40, description thereof will be omitted.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고는 축지지부재의 걸림돌기가 외측보강부재의 걸림홈에 걸리기 때문에 도어를 개폐할 때 도어에 대한 축지지부재의 회전이 제한된다. 따라서 도어의 개폐에 따른 마찰소음을 방지할 수 있는 효과가 있다.As described in detail above, the refrigerator according to the present invention is limited to the rotation of the shaft support member relative to the door when opening and closing the door because the locking projection of the shaft support member is caught by the locking groove of the outer reinforcing member. Therefore, there is an effect that can prevent the friction noise caused by the opening and closing of the door.

또한 본 발명은 도어의 축결합공 주위가 외측보강부재와 내측보강부재에 의해 지지될 뿐 아니라 내측보강부재의 제1곡면지지부가 축수용부 외면을 감싸는 형태로 지지하기 때문에 도어의 무게에 의해 축결합공 쪽에 큰 하중이 작용하는 경우에도 축결합공 쪽의 변형을 방지할 수 있는 효과가 있다. 따라서 장기간 사용하는 경우에도 도어의 개폐가 원활히 이루어지도록 할 수 있다.In addition, the present invention is not only supported by the outer reinforcing member and the inner reinforcing member around the shaft coupling hole of the door, but also supports the first curved support of the inner reinforcing member in the form of wrapping the outer surface of the bearing portion, Even when a large load is applied to the coupling hole side, there is an effect that can prevent deformation of the coupling hole side. Therefore, even when used for a long time it can be made to open and close the door smoothly.
