Description

냉기덕트 및 그를 구비한 냉장고{A Cool Air Duct and A Refrigerator having the Same}A Cool Air Duct and A Refrigerator having the Same}

본 발명은 냉장고에 관한 것으로, 보다 상세하게는 하부에 위치한 냉동실의 증발기로부터 냉장실 도어에 설치된 제빙장치로 냉기를 공급하고 제빙에 사용된 냉기를 다시 배출하여 냉동실로 유입시키는 냉기덕트와 그를 구비한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, a cold air duct for supplying cold air from an evaporator of a lower part of a freezer compartment located in a refrigerating compartment door to discharge the cold air used for ice making and introducing it into the freezer compartment and a refrigerator having the same. It is about.

일반적으로 냉장고는 압축기, 응축기, 팽창밸브, 증발기 등으로 이루어지는 냉동 사이클에 의해 생성된 냉기를 토출하여 고내의 온도를 저하시켜 음식물 등을 냉동시키거나 냉장 보관하는 장치이다.In general, a refrigerator is a device for freezing or refrigerating food or the like by discharging cold air generated by a refrigeration cycle including a compressor, a condenser, an expansion valve, an evaporator, and lowering the temperature in the refrigerator.

냉장고는 냉동실이 냉장실의 상부에 배치된 탑마운트 타입(Top Mount-Type)과, 냉동실이 냉장실의 하부에 배치된 바텀 프리저 타입(Bottom Freezer-Type)과, 냉동실과 냉장실이 좌/우측으로 구획된 사이드 바이 사이드 타입(Side By Side-Type)으로 나뉘어진다.The refrigerator includes a Top Mount-Type in which a freezer is disposed at the top of the refrigerator compartment, a Bottom Freezer-Type in which the freezer is disposed at the bottom of the refrigerator compartment, and a freezer and a refrigerator compartment are divided into left and right sides. It is divided into Side By Side-Type.

이 가운데 바텀 프리저 타입의 냉장고의 일례가 도 1에 도시되어 있다.An example of the bottom freezer type refrigerator is shown in FIG. 1.

도 1에 도시된 바와 같이 냉장고 본체(100)의 내부는 냉장실(200)과 냉동 실(300)로 구획된다. 냉장실(200)은 본체(100)의 상부에 형성된다. 냉장실(200)의 내부에는 다양한 종류의 음식물들을 효율적으로 수납하기 위한 선반 및 서랍들이 설치될 수 있다.As shown in FIG. 1, the inside of the refrigerator body 100 is divided into a refrigerating chamber 200 and a freezing chamber 300. The refrigerating chamber 200 is formed above the main body 100. Shelves and drawers for efficiently storing various types of food may be installed in the refrigerating chamber 200.

냉장실(200)은 본체(100)의 양측에 힌지회동가능하게 각각 결합된 냉장실도어(400)에 의해서 선택적으로 차폐된다. 냉장실도어(400)의 일측에는 얼음을 생성하며 생성된 얼음을 외부에서 인출할 수 있는 제빙장치(500)가 설치된다.The refrigerating chamber 200 is selectively shielded by the refrigerating chamber doors 400 respectively hinged to both sides of the main body 100 so as to be hinged. One side of the refrigerating chamber door 400 is provided with an ice making device 500 that generates ice and withdraws the generated ice from the outside.

제빙장치(500)에는 냉동실(300)의 증발기(320)로부터 유도된 냉기가 공급되어 제빙 작업을 수행하게 된다. 이를 위해 본체(100)의 일측 벽면 내측에는 냉기를 공급하고 배출시키는 한 쌍의 냉기덕트(700)가 설치된다. The ice making apparatus 500 is supplied with cold air induced from the evaporator 320 of the freezing chamber 300 to perform an ice making operation. To this end, a pair of cold air ducts 700 for supplying and discharging cold air are installed inside one side wall of the main body 100.

냉기덕트(700)는 냉동실(300)의 증발기(320)에서 발생된 냉기를 제빙장치(500)의 냉기공(520)으로 공급하는 공급덕트(720)와, 제빙장치(500)에서 열교환을 마친 냉기가 배출공(540)을 통과하여 다시 냉동실(300)로 배출되도록 하는 배출덕트(740)로 구성된다. The cold air duct 700 is a supply duct 720 for supplying the cold air generated in the evaporator 320 of the freezing chamber 300 to the cold air hole 520 of the ice making apparatus 500 and the heat exchange in the ice making apparatus 500 Cold air is passed through the discharge hole 540 is composed of a discharge duct 740 to be discharged back to the freezing chamber (300).

이러한 냉기덕트(700)는 금속재질로 만들어지는데, 냉장실(200)의 벽면에는 단열재가 충진되어 냉기덕트(700)를 통해 이송되는 냉기에 의해 냉장실(200) 내부의 온도에 변화가 발생하는 것을 방지하게 된다.The cold air duct 700 is made of a metal material, the wall surface of the refrigerating chamber 200 is filled with a heat insulating material to prevent the change in the temperature inside the refrigerating chamber 200 by the cold air transferred through the cold air duct (700). Done.

즉, 각각의 공급덕트(720)와 배출덕트(740)가 냉장고의 측벽에 설치된 후 측벽 내부 공간은 단열재로 충진된다. 그런데 단열재로 충진된 냉장고의 측벽 내부는 공급덕트(720)와 배출덕트(740)의 형상으로 인해 굴곡이 생기고 단열 두께에 차이가 발생한다.That is, after each of the supply duct 720 and the discharge duct 740 is installed on the side wall of the refrigerator, the interior space of the side wall is filled with a heat insulating material. However, due to the shape of the supply duct 720 and the discharge duct 740, the inside of the side wall of the refrigerator filled with the heat insulating material has a difference in the thickness of the heat insulation.

이러한 문제점을 개선하기 위해 도 2에 도시된 바와 같이 공급덕트(720)와 배출덕트(740)를 나란히 배치한 후 이들의 양 측면에는 판금재(800)를 부착하고, 판금재(800)에는 냉장고 내측 벽면과의 완충을 위한 고무패킹(900)을 장착한 어셈블리 형태의 냉기덕트(700)가 개시된다.To improve this problem, as shown in FIG. 2, after the supply duct 720 and the discharge duct 740 are arranged side by side, the sheet metal material 800 is attached to both sides thereof, and the sheet metal material 800 is a refrigerator. Disclosed is a cold air duct 700 in the form of an assembly with a rubber packing 900 for cushioning with an inner wall.

그리고 어셈블리 형태의 냉기덕트에는 발포액이 원활하게 충진되도록 하기 위한 유입구멍(810)이 공급덕트(720)과 배출덕트(740)의 중간부분에 형성된다.In the cold air duct of the assembly form, an inlet hole 810 is formed in the middle of the supply duct 720 and the discharge duct 740 to smoothly fill the foam liquid.

그런데 역설적으로 발포액을 유입하는 과정에서 유입구멍(810)으로 인해 불균일한 충진이 발생하여 냉장고의 측벽에 굴곡이 생기고, 금속재질의 냉기덕트 어셈블리는 여전히 냉장고 측벽면의 단열 두께 차이를 줄이지 못하는 문제가 있다.However, paradoxically, the inflow hole 810 causes inhomogeneous filling in the process of introducing the foam liquid, resulting in bending on the side wall of the refrigerator, and the metal cold air duct assembly still fails to reduce the difference in insulation thickness between the side walls of the refrigerator. There is.

따라서, 본 발명의 목적은 냉장고의 측벽면의 단열 두께 차이를 줄일 수 있으며 측벽에 굴곡이 발생하지 않도록 하는 냉기덕트와 그를 구비한 냉장고를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a cold air duct and a refrigerator having the same, which can reduce the difference in thermal insulation thickness of the side wall surface of the refrigerator and prevent bending of the side wall.

The discharge duct 84 serves as a passage through which the cold air that has completed heat exchange in the ice making device passes through the discharge hole (not shown) of the ice making device and is discharged back to the freezing chamber.

따라서, 공급덕트(82)와 배출덕트(84)의 일단은 냉장실과 연통되고, 타단이 냉동실과 연통되도록 구성된다. 즉, 공급덕트(82)와 배출덕트(84)의 일단은 제빙장치의 냉기공과 배출공에 각각 연통되게 설치되어야 한다. 이를 위해 상기 제1하우징(71) 또는 제2하우징(75)에는 상기 공급덕트(82), 상기 배출덕트(84)와 각각 연통되는 냉기 공급공(82a)과 냉기 배출공(84a)이 형성된다.Therefore, one end of the supply duct 82 and the discharge duct 84 is in communication with the refrigerating chamber, and the other end is configured to communicate with the freezing chamber. That is, one end of the supply duct 82 and the discharge duct 84 should be installed in communication with the cold air and the discharge hole of the ice making device, respectively. To this end, the first housing 71 or the second housing 75 is provided with a cold air supply hole 82a and a cold air discharge hole 84a communicating with the supply duct 82 and the discharge duct 84, respectively. .

냉기 공급공(82a)과 냉기 배출공(84a)은 본 실시예처럼 제2하우징(75)의 단부 영역에 원형의 형태를 갖도록 각각 형성될 수 있다. 냉기 공급공(82a)은 상기 제빙장치의 냉기공과 연통되고, 냉기 배출공은(84a)의 상기 제빙장치의 배출공에 각각 연결되게 위치된다.The cold air supply hole 82a and the cold air discharge hole 84a may be formed to have a circular shape in the end region of the second housing 75 as in the present embodiment. The cold air supply hole 82a communicates with the cold air hole of the ice making device, and the cold air discharge hole is positioned to be connected to the discharge hole of the ice making device of 84a, respectively.

한편, 하우징(70) 내부에 형성된 상기 공급덕트(82)와 배출덕트(84) 사이에는 공급덕트(82)와 배출덕트(84)를 단열시키는 단열공간부(85)가 마련된다. On the other hand, between the supply duct 82 and the discharge duct 84 formed in the housing 70 is provided a heat insulating space portion 85 to insulate the supply duct 82 and the discharge duct 84.

상기 단열공간부(85)는 공급덕트(82)와 배출덕트(84)를 형성하는 공급덕트 리브(72, 76)와 배출덕트 리브(73, 77)에 의해서 하우징(70)의 중앙영역에 마련되는 빈 공간일 수 있다. 이러한 단열공간부(85)는 서로 다른 온도의 냉기가 유동하는 공급덕트(82)와 배출덕트(84)가 상호 영향을 미치지 않도록 단열을 수행한다.The heat insulating space 85 is provided in the central region of the housing 70 by supply duct ribs 72 and 76 and discharge duct ribs 73 and 77 forming the supply duct 82 and the discharge duct 84. It can be an empty space. The thermal insulation space 85 is insulated so that the supply duct 82 and the discharge duct 84 through which cold air of different temperatures flow are not influenced mutually.

단열공간부(85)에는 단열재(86)가 개재되는 것이 바람직하다. 단열재(86)는 스티로폼, 유리질, 광물질, 금속질, 탄소질 단열재(86) 중 적어도 어느 하나가 선택되어 사용될 수 있다.It is preferable that the heat insulating material 86 is interposed in the heat insulation space part 85. The heat insulating material 86 may be selected from at least one of styrofoam, glass, mineral, metal, and carbonaceous heat insulating material 86.

도 5에 도시된 바와 같이 단열재(86)는 단열공간부(85)의 길이방향을 따라 채워질 수 있다. 단열재(86)가 채워진 단열공간부(85)는 빈 공간만 존재한 것에 비하여 단열효과를 더욱 증진시킬 수 있으므로 공급덕트(82)는 배출덕트(84)에 의해 열을 손실하지 않고 냉동실의 증발기로부터 냉기를 제빙장치에 공급할 수 있다.As shown in FIG. 5, the heat insulating material 86 may be filled along the longitudinal direction of the heat insulating space 85. Since the heat insulating space 85 filled with the heat insulating material 86 can further enhance the heat insulating effect compared to the presence of only the empty space, the supply duct 82 is discharged from the evaporator of the freezer without losing heat by the discharge duct 84. Cold air can be supplied to the ice maker.

한편, 상술한 공급덕트(83), 배출덕트(84) 및 단열공간부(85)가 형성된 하우징(70)은 강성이 플라스틱 재질로 이루어지는 것이 바람직하다. 그리고 제1하우징(71)과 제2하우징(75)은 플라스틱 사출물로 제작되어 공급덕트 리브(72, 76), 배출덕트 리브(73, 77)가 각각 형성될 수 있다. 따라서, 하나의 하우징(70) 내부에는 공급덕트(82), 배출덕트(84), 단열공간부(85)가 용이하게 형성될 수 있다.On the other hand, the housing 70 in which the above-described supply duct 83, the discharge duct 84 and the heat insulating space 85 is formed is preferably made of a plastic material. In addition, the first housing 71 and the second housing 75 may be made of a plastic injection molding so that the supply duct ribs 72 and 76 and the discharge duct ribs 73 and 77 may be formed, respectively. Therefore, the supply duct 82, the discharge duct 84, the heat insulating space 85 can be easily formed in one housing 70.

그리고 강성이 큰 플라스틱 소재로 이루어지는 하우징(70)은 종래 금속재질로 이루어진 냉기덕트 어셈블리에 비해 외부가 균일한 강성을 나타낼 수 있다. 또한, 무게를 가볍게 할 수 있으며 열전도를 낮추어 열 손실을 줄일 수 있는 효과도 제공한다.In addition, the housing 70 made of a plastic material having a large rigidity may exhibit uniform rigidity outside of the conventional cold air duct assembly made of a metal material. In addition, the weight can be reduced and the heat loss can be reduced by reducing the heat conduction.

한편, 하우징(70)의 외표면에는 다수의 패킹(90)이 결합될 수 있다.Meanwhile, a plurality of packings 90 may be coupled to an outer surface of the housing 70.

상기 패킹(90)은 고무 등 탄성있는 재질로 이루어지면서 냉기덕트의 하우징(70)이 냉장고의 내측벽에 설치될 때 내벽과 외벽에 접촉되어 그 위치를 고정하는 역할을 한다. 그리고 냉장고의 내측벽에 위치가 고정된 냉기덕트는 단열재로 발포작업이 진행된다.The packing 90 is made of an elastic material such as rubber and serves to fix the position by contacting the inner wall and the outer wall when the housing 70 of the cold air duct is installed on the inner wall of the refrigerator. And the cold air duct fixed in position on the inner wall of the refrigerator is a foaming operation proceeds as a heat insulating material.

이때 종래의 냉기덕트 어셈블리는 발포액을 유입하는 과정에서 발포액의 유입구멍, 금속재질 및 이원화된 한 쌍의 냉기덕트 등의 구성으로 인해 냉장고 측벽에 굴곡이 발생하는 문제가 발생하였다.At this time, the conventional cold air duct assembly has a problem in that bending occurs in the side wall of the refrigerator due to the configuration of the inlet hole of the foam liquid, the metal material and a pair of cold air duct in the dual process.

그러나 본 발명의 냉기덕트는 하나의 하우징(70) 내부에 공급덕트(82)와 배기덕트를 일원화시키고 강성이 큰 플라스틱 재질로 이루어지므로 냉장고의 측벽에 굴곡이 생기지 않을 뿐만 아니라 측벽면의 단열 두께에 차이를 줄일 수 있다.However, since the cold air duct of the present invention unitizes the supply duct 82 and the exhaust duct inside one housing 70 and is made of a rigid plastic material, not only the bending of the side wall of the refrigerator occurs, but also the insulation thickness of the side wall surface. The difference can be reduced.

도 6은 본 발명의 다른 실시예에 따른 냉기덕트에 대한 단면도이다.6 is a cross-sectional view of a cold air duct according to another embodiment of the present invention.

상기 제1하우징(71a)의 내측 중앙영역에는 서로 이격된 공급덕트 리브(72a)와 배출덕트(73a)가 돌출 형성되고, 양측 가장자리 영역은 평평한 형상으로 이루어진다.The supply duct ribs 72a and the discharge ducts 73a, which are spaced apart from each other, protrude from the inner central region of the first housing 71a, and both edge regions have a flat shape.

그리고 제2하우징(75a)의 중앙영역에는 서로 이격된 공급덕트 리브(76a)와 배출덕트 리브(77a)가 형성되고, 양측 가장자리 영역에도 공급덕트 리브(76a)와 배출덕트리브(77a)가 형성되어 있다.In addition, the supply duct ribs 76a and the discharge duct ribs 77a, which are spaced apart from each other, are formed in the center region of the second housing 75a, and the supply duct ribs 76a and the discharge duct ribs 77a are formed in both edge regions thereof. It is.

상기 제1하우징(71a)과 제2하우징(75a)이 조립될 때, 제1하우징(71a)은 덮개 형상으로 제2하우징(75a)을 덮는 모양으로 결합한다. When the first housing 71a and the second housing 75a are assembled, the first housing 71a is coupled in a shape of covering the second housing 75a in a lid shape.

그리고 제1하우징(71a)의 공급덕트 리브(72a)는 제2하우징(75a)의 공급덕트(76a) 내측에 인접하게 결합되고, 제1하우징(71a)의 배출덕트(73a)는 제2하우징(75a)의 배출덕트(77a) 내측에 인접하게 결합된다. The supply duct rib 72a of the first housing 71a is coupled to the inside of the supply duct 76a of the second housing 75a and the discharge duct 73a of the first housing 71a is connected to the second housing. It is coupled adjacent to the discharge duct 77a of the 75a.

이러한 결합관계로 하우징(70a) 내부에는 전술한 바와 같은 공급덕트(82)와 배출덕트(84) 및 단열공간부(85)가 형성된다. Due to such a coupling relationship, the supply duct 82, the discharge duct 84, and the heat insulating space 85 as described above are formed in the housing 70 a.
