Description

냉장고{REFRIGERATOR}Refrigerator {REFRIGERATOR}

본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 본체의 외상과 내상 사이에 발포단열재가 채워질 때 내상과 접하는 쪽에 빈 공간이 형성되지 않도록 하는 발포안내수단을 구비하는 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator having foam guide means for preventing empty spaces from being formed in contact with the inner wound when the foam insulation is filled between the outer and inner wounds of the main body.

일반적으로 냉장고는 냉각장치에서 생성된 냉기를 저장실 내부로 공급하여 저장실이 차가운 상태가 되도록 함으로써 보관된 저장물의 신선도를 장기간 유지시킬 수 있도록 한 장치이다.In general, the refrigerator is a device that can maintain the freshness of the stored storage for a long time by supplying the cold air generated in the cooling device into the storage compartment to make the storage compartment cool.

이러한 냉장고의 본체는 도 1에 도시한 바와 같이, 내부의 저장실(1)이 외부와 단열될 수 있도록 통상 외면을 이루는 외상(2)과 저장실(1)의 내면을 이루는 내상(3)을 구비하며, 외상(2)과 내상(3) 사이에는 발포단열재(4)가 채워진다. 그리고 이 발포단열재(4)의 충진작업은 냉장고 본체를 제조하는 단계에서 이루어진다.As shown in FIG. 1, the main body of the refrigerator includes an outer box 2 forming an outer surface and an inner box 3 forming an inner surface of the storage room 1 so that the storage compartment 1 of the refrigerator may be insulated from the outside. Between the outer box 2 and the inner box 3, the foam insulation 4 is filled. And the filling operation of the foam insulation 4 is made in the step of manufacturing the refrigerator body.

이러한 본체를 제조할 때는 통상 철판을 절곡시켜 외상(2)을 만들고, 플라스틱 수지재로 마련된 패널을 성형시켜서 그 내면이 저장실(1)을 이루는 내상(3)을 만든다. 그리고 외상(2)의 내부에 내상(3)을 결합시킨 후, 외상(2)과 내상(3) 사이의 이격된 공간에 발포단열재(4)를 충진시킨다.When manufacturing the main body, the iron plate is usually bent to make an outer box 2, and a panel made of a plastic resin material is molded to form an inner box 3 whose inner surface forms the storage chamber 1. Then, after the inner phase 3 is coupled to the inside of the trauma 2, the foam insulation 4 is filled in the spaced space between the trauma 2 and the inner phase 3.

발포단열재(4)를 충진시킬 때는 통상 본체 하부의 기계실(5) 쪽에 마련되는 주입구(6)를 통해 소정의 압력으로 발포단열재(4)를 주입하면 발포단열재(4)가 외상(2)과 내상(3) 사이의 이격된 공간 전체로 퍼지면서 채워진다. 이때 본체의 내부에 채워지는 발포단열재(4)는 주입구(6)의 방향에 따라 주입구(6)로부터 도면상의 "A"방향, 즉 본체의 상부 쪽으로 먼저 주입되면서 채워진 후 최종적으로 도면상의 "B"방향, 즉 본체의 하부 쪽에 채워진다.When the foam insulation 4 is filled, the foam insulation 4 is injected at a predetermined pressure through the injection port 6 provided on the machine room 5 side of the lower part of the main body. (3) It is filled while spreading throughout the space between them. At this time, the foam insulation 4 to be filled in the interior of the main body is filled while being first injected from the injection hole 6 in the direction "A" on the drawing, that is, toward the upper part of the main body according to the direction of the injection hole 6, and finally "B" on the drawing. Direction, ie the lower side of the body.

그런데 이러한 방법으로 발포단열재(4)가 충진되는 종래 냉장고의 본체는 최종적으로 본체의 하부 쪽에 발포단열재(4)가 채워질 때 내부의 공기가 몰리기 때문에 일부공간에 발포단열재(4)가 충진되지 않아 빈 공간(7)이 생기는 문제점이 있었다.However, in the conventional refrigerator main body in which the foam insulation 4 is filled in this manner, since the air inside is filled when the foam insulation 4 is finally filled to the lower side of the main body, the foam insulation 4 is not filled in the space. There was a problem that the space 7 was created.

특히 본체의 하부 쪽으로 진입하는 발포단열재(4)는 발포단열재(4)의 유동방향(B방향)에 따라 외상(2)의 내면 쪽이 먼저 채워진 후, 내상(3) 쪽이 채워지기 때문에 내부의 공기가 내상(3) 쪽으로 몰려 내상(3)과 접하는 쪽에 빈 공간(7)이 생기는데, 이는 상대적으로 재질이 약한 내상(3) 바닥의 변형을 초래하는 원인이 되었다.In particular, the foam insulation 4 entering the lower portion of the main body is first filled with the inner surface side of the outer shell 2 according to the flow direction (B direction) of the foam insulation 4, and then the inner shell 3 side is filled with The air rushes toward the inner box 3, creating an empty space 7 on the side in contact with the inner box 3, which causes deformation of the floor of the relatively weak material of the inner box 3.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 본체의 하부에 발포단열재가 채워질 때 내상과 접하는 쪽에 공기에 의한 빈공간이 형성되지 않도록 하여 내상의 변형을 방지할 수 있도록 하는 냉장고를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to prevent the deformation of the inner phase by preventing the empty space by the air formed on the side in contact with the inner wound when the foam insulation is filled in the lower part of the main body To provide.

본 발명에 따른 냉장고는 도 2와 도 3에 도시한 바와 같이, 본체(10) 상부의 냉동실(11)과 하부의 냉장실(12)이 중간벽(13)에 의해 구획되며, 냉동실(11)과 냉장실(12)의 전면이 개방된 구조로 마련된다. 그리고 이러한 본체(10)는 외면을 형성하는 외상(14)의 내부에 냉동실(11)과 냉장실(12)의 내면을 형성하는 내상(15)이 이격된 상태로 결합되며, 외상(14)과 내상(15) 사이의 공간에 냉동실(11)과 냉장실(12)의 보온을 위한 발포단열재(16)가 충진 된다. 즉 본체(10)는 외상(14)과 내상(15)이 결합된 상태에서 외상(14)의 후면 하단에 형성된 주입구(17)를 통해 발포단열재(16)가 주입됨으로써 단열 벽체를 이루도록 구성된다.In the refrigerator according to the present invention, as shown in FIGS. 2 and 3, the freezing compartment 11 of the upper part of the main body 10 and the refrigerating compartment 12 of the lower part are partitioned by the intermediate wall 13, and the freezing compartment 11 and The front surface of the refrigerating chamber 12 is provided in an open structure. In addition, the main body 10 is coupled to the inner wound 15 forming the inner surface of the freezing chamber 11 and the refrigerating chamber 12 spaced apart from the inside of the outer wound 14 forming the outer surface, the outer wound 14 and the inner wound The space between the (15) is filled with a foam insulation 16 for the insulation of the freezing chamber 11 and the refrigerating chamber 12. That is, the main body 10 is configured to form a heat insulation wall by injecting the foam insulation 16 through the injection hole 17 formed in the lower end of the rear surface of the outer wound 14 and the inner wound 15.

본체(10)의 외상(14)은 통상 철판의 절곡 성형을 통해 마련되며, 외상(14)의 내부에 결합되는 내상(15)은 플라스틱 수지재의 성형을 통해 마련된다. 그리고 이러한 본체(10)를 제작할 때는 외상(14)과 내상(15) 사이의 공간이 이격되도록 상호 결합시킨 후, 본체(10) 하단의 기계실(18)에 형성된 주입구(17)에 발포액 주입장치(19)를 연결시켜 발포단열재(16)를 충진시키는 방식을 취한다.The outer shell 14 of the main body 10 is usually provided through bending molding of an iron plate, and the inner wound 15 coupled to the inside of the outer box 14 is provided through molding of a plastic resin material. When the main body 10 is manufactured, the spaces between the outer trauma 14 and the inner trauma 15 are coupled to each other so as to be spaced apart, and then the foam liquid injection device is injected into the injection hole 17 formed in the machine chamber 18 at the lower end of the main body 10. (19) is connected to take the form of filling the foam insulation (16).

발포단열재(16)가 채워지는 순서는 주입구(17)가 기계실(18) 쪽에 마련되고, 주입구(17)를 통한 토출방향이 본체(10)의 상부, 즉 도면상의 "A"방향을 향하도록 배치되기 때문에 발포단열재(16)가 본체(10)의 상부와 중간벽(13) 쪽으로 먼저 밀려들어가면서 채워진다. 그리고 상부 쪽에 발포단열재(16)가 거의 채워진 후에는 최종적으로 본체(10)의 하부 쪽, 즉 도면상의 "B"방향으로 밀려들어가면서 채워진다.In order for the foam insulation material 16 to be filled, the injection hole 17 is provided on the machine room 18 side, and the discharge direction through the injection hole 17 is disposed so as to face the upper portion of the main body 10, that is, the "A" direction in the drawing. Since the foam insulation 16 is first pushed toward the upper portion and the intermediate wall 13 of the main body 10 is filled. After the foam insulation 16 is almost filled in the upper side, the foam insulation material is finally pushed into the lower side of the main body 10, that is, in the direction "B" on the drawing.

이때 본체(10)의 하부 쪽으로 채워지는 발포단열재(16)는 발포단열재의 유동방향에 따라 본체(10)의 외상(14) 쪽(바닥 쪽)으로 먼저 밀려들면서 채워지려 하게 되는데, 본 발명은 이러한 발포단열재(16)의 유동방향을 내상(15) 쪽으로 유도하여 내상(15) 쪽에 발포단열재(16)가 먼저 채워지도록 하기 위한 발포안내부재(20)를 구비한다. 즉 발포안내부재(20)를 통해 본체(10)의 하부에 채워지는 발포단열재(16)가 내상(15) 쪽에 먼저 채워진 후 외상(14) 쪽에 채워지도록 한다.At this time, the foam insulation 16 to be filled toward the lower side of the main body 10 is to be filled by first pushing the outer side 14 (bottom side) of the main body 10 according to the flow direction of the foam insulation, the present invention is such It is provided with a foam guide member 20 for guiding the flow direction of the foam insulation 16 toward the inner phase 15 so that the foam insulation 16 is first filled in the inner phase 15. That is, the foam insulation 16 to be filled in the lower portion of the main body 10 through the foam guide member 20 is first filled in the inner wound 15 side and then filled in the outer wound 14 side.

이를 위한 발포안내부재(20)는 소정의 높이를 구비하고 본체(10)의 횡 방향 폭과 거의 대응하는 길이를 구비하는 막대형상으로 마련되며, 본체(10) 하부의 외상(15) 내면에 부착된다. 또한 발포안내부재(20)는 발포단열재(16)의 유동방향(B방향)에 대하여 교차하는 방향으로 길게 설치된다.The foam guide member 20 for this purpose is provided in a rod shape having a predetermined height and having a length substantially corresponding to the lateral width of the main body 10, and attached to the inner surface of the outer shell 15 under the main body 10. do. In addition, the foam guide member 20 is installed long in the direction crossing with respect to the flow direction (B direction) of the foam insulation (16).

이는 발포안내부재(20)를 통해 외상(14)의 내면 쪽으로부터 소정의 높이로 돌출하는 턱이 형성되도록 함으로써 발포단열재(16)가 외상(14) 쪽으로 유동하는 현상을 제한하여 내상(15) 쪽에 먼저 채워지도록 한 것이다. 이때 발포안내부재(20)의 높이는 내상(15)과 외상(14)사이의 간격보다 작도록 하여 발포단열재(16)가 발포안내부재(20)를 넘어서 유동할 수 있도록 한다.This allows the jaw to protrude from the inner surface side of the trauma 14 to the predetermined height through the foam guide member 20 to limit the phenomenon that the foam insulation 16 flows toward the trauma 14 to the inner wound 15 side. It is to be filled first. At this time, the height of the foam guide member 20 is smaller than the gap between the inner wound 15 and the outer wound 14 to allow the foam insulation 16 to flow beyond the foam guide member 20.

이러한 방식으로 발포단열재(16)가 충진되면, 외상(14)과 내상(15) 사이의 공기가 본체(10) 하부의 내상(15) 쪽으로 몰리는 현상이 방지될 뿐 아니라, 내부의공기가 본체(10) 하부의 바닥면(외상)에 마련되는 에어벤트를 통해 배출될 수 있기 때문에 본체(10)의 하부에 발포단열재(16)가 균일하게 채워질 수 있게 된다.When the foam insulation 16 is filled in this manner, the air between the outer wound 14 and the inner wound 15 is prevented from being driven toward the inner wound 15 of the lower portion of the main body 10, and the air inside the main body ( 10) Since it can be discharged through the air vent provided on the bottom surface (trauma) of the lower it is possible to uniformly fill the foam insulation 16 in the lower portion of the main body (10).

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고는 발포안내부재를 통해 본체의 하부에 발포단열재가 내상 쪽으로 안내됨으로써 내상 쪽으로 먼저 채워진 후 외상 쪽에 채워지기 때문에, 본체의 내상 쪽에 공기에 의한 빈공간이 형성되지 않아 내상의 변형을 방지할 수 있는 효과가 있다.As described in detail above, the refrigerator according to the present invention is filled with the outer outer side after the foam insulation is guided to the inner inner side by the foam insulation member guided to the inner inner side through the foam guide member, so that the empty space by the air on the inner inner side of the main body Since it is not formed there is an effect that can prevent the deformation of the internal wound.
