It further includes a support member 37 for supporting the rotating member 31 when the 23 seals the receiving space (11).

회동부재(31)는 상단 및 하단에 힌지축(31a)이 구비되고, 힌지축(31a)을 통해 설치공간부(25)에 회동가능하게 힌지 결합된다. 이때, 설치공간부(25)에는 힌지축(31a)을 장착하기 위한 결합구멍(도시생략)이 형성된다.Rotating member 31 is provided with a hinge shaft (31a) at the top and bottom, is hinged rotatably to the installation space portion 25 through the hinge shaft (31a). At this time, the installation space 25 is formed with a coupling hole (not shown) for mounting the hinge shaft (31a).

또한, 회동부재(31)는 밀폐부재(33)가 삽입되어 고정되는 결합홈부(31b)가 홈 형태로 형성되고, 결합홈부(31b)의 내부에 밀폐부재(33)의 이탈을 방지하는 이탈방지리브(31c)가 돌출 형성된다.In addition, the rotation member 31 has a coupling groove 31b into which the sealing member 33 is inserted and fixed is formed in a groove shape, and prevents the separation of the sealing member 33 to prevent separation of the sealing member 33 inside the coupling groove 31b. The rib 31c protrudes.

본 실시 예에서는 힌지축(31a)이 회동부재(31)에 구비되는 것을 예를 들어 설명하고 있지만, 힌지축(31a)을 설치공간부(25)의 내부에 형성하고, 상기 결합구멍을 회동부재(31)에 형성할 수도 있다.In this embodiment, the hinge shaft 31a is provided in the rotation member 31 by way of example, but the hinge shaft 31a is formed inside the installation space 25, and the coupling hole is formed in the rotation member. It can also be formed in (31).

회동부재(31)에 결합되어 냉동실 도어(21)와 냉장실 도어(23) 사이를 밀폐시키는 밀폐부재(33)는 밀폐를 위한 접촉부(33a)와, 접촉부(33a)에서 연장 형성되어 회동부재(31)에 결합되는 고정부(33b)가 구비된다.The sealing member 33 coupled to the rotating member 31 to seal between the freezer compartment door 21 and the refrigerating compartment door 23 is formed to extend from the contact portion 33a and the contact portion 33a to seal the rotation member 31. It is provided with a fixing portion (33b) coupled to.

또한, 밀폐부재(33)는 상호 접촉되는 접촉부(33a)의 접촉력 및 접촉면적을 감소시킬 수 있는 간섭 방지부(33c)가 더 구비된다.In addition, the sealing member 33 is further provided with an interference prevention portion 33c that can reduce the contact force and the contact area of the contact portion 33a in contact with each other.

이러한, 밀폐부재(33)는 상호 접촉 또는 이격됨에 따라 그 형태가 변형되도록 탄력성을 가지는 고무에 의해 제작된다.Such, the sealing member 33 is made of rubber having elasticity so that its shape is deformed as they are contacted or spaced apart from each other.

밀폐부재(33)의 고정부(33b)는 회동부재(31)에 용이하게 삽입되어 결합되도록 쐐기형태를 가지며, 이탈방지리브(31c)에 걸려 결합홈부(31b)에서 이탈되는 것이 방지된다.The fixing part 33b of the sealing member 33 has a wedge shape so as to be easily inserted into and coupled to the rotation member 31, and is prevented from being caught from the coupling groove part 31b by being caught by the release preventing rib 31c.

간섭 방지부(33c)는 냉동실 도어(21) 또는 냉장실 도어(23)가 수용공간(11)을 개방하도록 회전하게 되면 회동부재(31)의 회동에 의해 상호 접촉되는 밀폐부재(33)의 접촉을 감소시키거나 또는 간섭을 방지하게 된다. 이를 위하여, 간섭 방지부(33c)는 밀폐부재(33)의 접촉부(33a)에서 라운드 형태로 형성된다.The interference prevention part 33c contacts the sealing member 33 which is in contact with each other by the rotation of the rotation member 31 when the freezing compartment door 21 or the refrigerating compartment door 23 rotates to open the accommodation space 11. Reduce or prevent interference. To this end, the interference prevention part 33c is formed in a round shape at the contact part 33a of the sealing member 33.

한편, 탄성부재(35)는 회동부재(31)의 힌지축(31a)에 결합되어 회동부재(31)를 도어(20)가 개방되는 방향으로 탄성 지지하게 된다. 이로 인하여, 냉동실 도어(21)와 냉장실 도어(23) 중 어느 하나의 도어(20)가 개방될 때 탄성부재(35)에 의해 회동부재(31)가 회동되므로, 간섭 방지부(33c)에 의한 밀폐부재(33)의 간섭이 보다 효과적으로 방지된다.On the other hand, the elastic member 35 is coupled to the hinge shaft (31a) of the rotating member 31 to elastically support the rotating member 31 in the direction in which the door 20 is opened. For this reason, since the rotation member 31 is rotated by the elastic member 35 when any one door 20 of the freezer compartment door 21 and the refrigerating compartment door 23 is opened, the interference prevention part 33c Interference of the sealing member 33 is more effectively prevented.
