Abstract

PURPOSE: A door apparatus of a refrigerator is provided to prevent a gasket from being separated and to inhibit defects in sealing a gasket and friction noise by preventing excess contact between the gasket and a case when a door is opened/closed. CONSTITUTION: A refrigerator door(30) is rotated counterclockwise to be opened when a user pulls the refrigerator door forward with a grip groove(31) on a side of the refrigerator door. A hinge axis(52) of an intermediate hinge member(50) is separated from a small circular groove of a hinge groove(33) when the refrigerator door is opened. As the hinge axis is positioned at a large circular groove, a gasket is moved forward the user and the refrigerator door is kept at a tilt angle(alpha). The gasket is kept loose in contact from a case(10) or separated with a distance to inhibit friction noise. When the refrigerator door is closed by a pushing force toward the case, the refrigerator door is rotated clockwise to be closed. The hinge axis is returned to the small circular groove from the larger groove when the door is closed. The gasket is moved toward the case and adhered to the case softly. Therefore, the refrigerator door is closed.

본 발명에 의한 냉장고에 있어서, 도3 내지 도6에 도시한 바와 같이 냉동실도어(20)의 일측단 측면 하단에는 손잡이홈(21)이 형성되어 있고, 그 타측단 상면에는 상기 상측 힌지부재(40)에 돌설된 힌지축(41)에 끼워맞춤되어 회전 자유롭게 결합되도록 힌지홈(22)이 형성되어 있으며, 그 타측단 하면에는 상기 중간측 힌지부재(50)에 돌설된 상부 힌지축(51)에 끼워맞춤되어 회전 자유롭게 결합되도록 힌지홈(23)이 형성되어 있다.In the refrigerator according to the present invention, as illustrated in FIGS. 3 to 6, a handle groove 21 is formed at one side end lower surface of the freezing chamber door 20, and the upper hinge member 40 is formed on the other end upper surface thereof. A hinge groove 22 is formed to fit to the hinge shaft 41 protruding from the hinge and to be rotatably coupled to the upper hinge shaft 51 protruding from the intermediate hinge member 50. A hinge groove 23 is formed to fit and rotate freely.

상기 냉장실도어(30)의 일측단 상면에는 손잡이홈(31)이 형성되어 있고, 그 타측단 상면에는 상기 중간측 힌지부재(50)에 돌설된 하부 힌지축(52)에 끼워맞춤되어 회전 자유롭게 결합되도록 힌지롬(33)이 형성되어 있으며, 그 타측단 하면에는 상기 하측 힌지부재(60)에 돌설된 힌지축(61)에 끼워맞춤되어 회전 자유롭게 결합되도록 힌지홈(32)이 형성되어 있다.A handle groove 31 is formed on an upper surface of one end of the refrigerating chamber door 30, and an upper surface of the refrigerating chamber 30 is fitted to the lower hinge shaft 52 protruding from the intermediate hinge member 50 to be rotatably coupled thereto. A hinge rom 33 is formed to be formed, and a hinge groove 32 is formed on the bottom end of the other end so as to fit on the hinge shaft 61 protruding from the lower hinge member 60 and to be freely coupled to the hinge shaft 61.

이때, 상기 힌지홈(22)(33)은 상기 냉동 및 냉장실도어(20)(30)가 열리고 닫일 때 상기 상하측 힌지부재(40)(60)의 힌지축(41)(61)을 중심으로 원운동을 하도록 원형상으로 형성되어 있고, 상기 힌지홈(23)(33)은 냉동 및 냉장실도어(20)(30)가 열리고 닫일 때 상기 중간측 힌지부재(50)의 상부 및 하부 힌지축(51)(52)을 중심으로 편심운동하도록 다원(多圓)형상으로 형성되어 있다.At this time, the hinge grooves 22 and 33 are centered on the hinge shafts 41 and 61 of the upper and lower hinge members 40 and 60 when the freezing and refrigerating chamber doors 20 and 30 are opened and closed. It is formed in a circular shape to the circular motion, the hinge grooves 23 and 33 are the upper and lower hinge shafts of the intermediate hinge member 50 when the freezing and refrigerating chamber doors 20 and 30 are opened and closed. 51 and 52 are formed in a plural shape so as to eccentrically move around them.

즉, 상기 힌지홈(23)(33)은 상기 냉동 및 냉장실도어(20)(30)가 각각 열릴 때 냉동실도어(20)의 하단과 냉장실도어(30)의 상단이 사용자의 앞으로 일정거리 이동되면서 전체적으로 냉동 및 냉장실도어(20)(30)가 일정한 기울임 각도(α)로 유지되도록 큰 원홈(33a)이 형성되어 있고, 상기 큰 원홈(33a)에 대하여 사용자의 앞쪽단에는 상기 냉동 및 냉장실도어(20)(30)가 각각 닫일 때 냉동실도어(20)의 하단과 냉장실도어(30)의 상단이 상기 케이스(10)쪽으로 일정거리 이동되면서 냉동 및 냉장실도어(20)(30)가 기울러지지 않게 유지되도록 작은 원홈(33b)이 연결 형성 되어 있다.That is, the hinge grooves 23 and 33 are moved to the front of the user by a certain distance in front of the lower end of the freezer compartment 20 and the refrigerating compartment door 30 when the freezing and refrigerating chamber doors 20 and 30 are respectively opened. A large one groove 33a is formed so as to maintain the freezing and refrigerating chamber doors 20 and 30 at a constant tilt angle α as a whole, and the freezing and refrigerating chamber door (at the front end of the user with respect to the large one groove 33a). When the 20 and 30 are closed, respectively, the lower end of the freezer compartment door 20 and the upper end of the refrigerating compartment door 30 are moved a predetermined distance toward the case 10 to keep the freezing and refrigerating compartment doors 20 and 30 not inclined. The small one groove 33b is formed so as to be connected.

다음에, 이와 같이 구성된 본 발명의 작용 및 효과를 설명한다.Next, the operation and effect of the present invention thus constructed will be described.

냉동실도어(20)의 하단과 냉장실도어(30)의 상단은 중간측 힌지부재(50)의 상부 및 하부 힌지축(51)(52)에 서로 대향되게 결합되어 동일한 구성으로 개폐되도록 되어 있으므로, 이하에서는 설명의 편의를 위하여 냉장실도어(30)와 중간측 힌지부재(50)와의 결합 관계에 대해서만 설명한다.The lower end of the freezer compartment door 20 and the upper end of the refrigerating compartment door 30 are coupled to the upper and lower hinge shafts 51 and 52 of the intermediate hinge member 50 so as to be opened and closed in the same configuration. In the following description, only the coupling relationship between the refrigerating chamber door 30 and the intermediate hinge member 50 will be described.

도5에 도시한 상태에서 냉장실도어(30)의 일측단 상면에 형성된 손잡이홈(31)을 이용하여 냉장실도어(30)를 사용자의 앞쪽으로 잡아당기는 힘에 의해 열게되면, 이 냉장실도어(30)는 그 타측단의 상면에 형성된 힌지홈(33)과 중간측 힌지부재(50)의 하부 힌지축(52)과의 결합에 의한 회전 중심에 따라 일방향(반시계방향)으로 회전되면서 도6에 도시한 바와 같이 열리게 된다.When the refrigerator compartment door 30 is opened by a force pulling the front of the user using the handle groove 31 formed on the upper end side of the refrigerator compartment door 30 in the state shown in FIG. 5, the refrigerator compartment door 30 is provided. 6 is rotated in one direction (counterclockwise) according to the rotation center by the combination of the hinge groove 33 formed on the upper surface of the other end and the lower hinge shaft 52 of the intermediate hinge member 50 is shown in FIG. Open as one.

이때, 중간측 힌지부재(50)의 힌지축(52)은 냉장실도어(30)가 열릴 때 힌지홈(33)의 작은 원홈(33b)에서 이탈됨과 동시에 큰 원홈(33a)에 위치됨에 따라 냉장실도어(30)의 상단과 냉장실도어(30)의 안쪽면에 부착된 가스켓(70)이 사용자의 앞쪽으로 이동되고, 냉장실도어(30)는 도4의 이점쇄선으로 도시된 바와 같이 일정한 기울임 각도(α)로 유지된다.At this time, the hinge shaft 52 of the intermediate hinge member 50 is separated from the small one groove 33b of the hinge groove 33 when the refrigerator compartment door 30 is opened and located in the large one groove 33a at the same time. The gasket 70 attached to the upper end of the 30 and the inner surface of the refrigerating chamber door 30 is moved toward the front of the user, and the refrigerating chamber door 30 has a constant tilt angle as shown by the dashed line in FIG. Is maintained.

그리고, 상기 가스켓(70)은 케이스(10)로부터 접촉상태가 느슨하게 유지되거나 또는 일정거리로 떨어지게 유지되면서 마찰소음을 일으키지 않게 된다.In addition, the gasket 70 does not cause friction noise while keeping the contact state loose from the case 10 or falling apart at a predetermined distance.

한편, 도6의 상태에서 냉장실도어(30)를 케이스(10)를 향하여 미는 힘에 의해 닫게 되면, 이 냉장실도어(30)는 그 타측단의 상면에 형성된 힌지홈(33)과 중간측 힌지부재(50)의 하부 힌지축(52)과의 결합에 의한 회전 중심에 따라 반대방향(시계방향)으로 회전되면서 도5에 도시한 바와 같이 닫히게 된다.Meanwhile, when the refrigerating chamber door 30 is closed by the force pushing toward the case 10 in the state of FIG. 6, the refrigerating chamber door 30 has a hinge groove 33 and an intermediate hinge member formed on the upper surface of the other end thereof. It rotates in the opposite direction (clockwise) along the rotation center by engagement with the lower hinge shaft 52 of the 50 and closes as shown in FIG.

이때, 중간측 힌지부재(50)의 힌지축(52)은 냉장실도어(30)가 닫힐 때 힌지홈(33)의 큰 원홈(33a)에서 작은 원홈(33b)에 우치됨에 따라 냉장실도어(30)의 상단과 냉장실도어(30)의 안쪽면에 부착된 가스켓(70)이 케이스(10)쪽으로 이동되고, 냉장실도어(30)는 도4의 실선으로 도시한 바와 같이 유지된다.At this time, the hinge shaft 52 of the intermediate hinge member 50 is placed in the small one groove 33b in the large one groove 33a of the hinge groove 33 when the refrigerator compartment door 30 is closed. The gasket 70 attached to the upper end of the refrigerator compartment door 30 and the inner surface of the refrigerator compartment door 30 is moved toward the case 10, and the refrigerator compartment door 30 is maintained as shown by the solid line of FIG. 4.

그리고, 상기 가스켓(70)은 냉장실도어(30)가 닫힐 때 케이스(10)에 부드럽게 밀착되면서 케이스(10)와 냉장실도어(30)와의 사이를 긴밀하게 밀폐시키게 된다.When the refrigerating chamber door 30 is closed, the gasket 70 closely closes between the case 10 and the refrigerating chamber door 30 when the refrigerating chamber door 30 is closed.

이상에서 설명한 바와 같이 본 발명에 따른 냉장고의 도어장치에 의하면, 도어가 열리고 닫힐 때 도어가 힌지되는 중심의 도어부분이 앞쪽으로 일정거리 이동되면서 전체적으로 도어의 기울임 각도를 주도록 한 구조로 되어 있기 때문에 가스켓과 케이스와의 무리한 접촉이 일어나지 않게 함에 따라 가스켓이 밀리거나 또는 십히는 현상을 방지하여 가스켓의 이탈을 방지하고, 이로 인하여 가스켓의 밀폐불량 및 마찰소음을 미연에 방지할 수 있는 효과가 있다.As described above, according to the door apparatus of the refrigerator according to the present invention, when the door is opened and closed, the center part of the door where the door is hinged is moved forward by a predetermined distance so that the overall tilting angle of the door is provided. By preventing excessive contact between the case and the gasket prevents the gasket from being pushed or buckled to prevent the departure of the gasket, thereby preventing the poor sealing and friction noise of the gasket in advance.
