또한 덮개(5)에 형성된 냉기통로(6)는 절연판(7)을 부착 시켜 냉동실(1) 내부의 온도차로 인한 결빙을 방지해야 됨으로 구성이 복잡해진다. 또한 냉기통로(6)의 하단과 토출구(2a)에 연결구(8)를 설치하여 이들을 서로 연결시켜야 됨으로 조립성이 저하되는 단점이 있다.In addition, the cold air passage 6 formed in the cover 5 is attached to the insulating plate 7 to prevent the freezing due to the temperature difference inside the freezer compartment 1 is complicated in configuration. In addition, there is a disadvantage in that the assembling property is deteriorated because the connection port 8 is installed at the lower end of the cold air passage 6 and the discharge port 2a to be connected to each other.
본 발명자는 이러한 문제점을 감안하여 냉동실 후방의 내상에 냉기통로를 직접 형성하고 냉동실과 냉장실이 덕트에 의해, 서로 연결되도록 함으로서, 구성을 간소화시킨 냉장고의 냉기순환장치를 선출원 중에 있다. 본 발명은 선출원된 냉기순환장치의 개선에 관한 것으로서, 그 목적은 냉동실의 후방에 형성된 냉기 통로와 냉장실 상부의 토출구를 연결하는 덕트의 용기와 커버가 한 변이 서로 연결되어 접어지도록 하고 또한 포개지는 접촉부위에 돌기와 홈을 형성하여 서로 결합되도록 함으로서, 밀폐력과 조립성이 향상되도록 한 냉장고의 냉기순환장치를 제공함이 있다.In view of the above problems, the present inventors have previously filed a cold air circulation system for a refrigerator which simplifies the configuration by directly forming a cold air passage on the inside of the rear of the freezer compartment and allowing the freezer compartment and the refrigerating compartment to be connected to each other by a duct.

이하에서는 본 발명의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 발명 냉장고의 측단면도 이고 제3도는 본 발명 냉기순환장치의 사시도 이다. 본 발명의 냉장고는 냉동실(10)과 냉장실(11)로 분리 구성되고 이들을 구성하는 내, 외상(13)(14) 사이에 단열재(15)가 충진되어 내부가 단열된다.Figure 2 is a side cross-sectional view of the refrigerator of the present invention and Figure 3 is a perspective view of the cold air circulation device of the present invention. The refrigerator of the present invention is divided into a freezer compartment 10 and a refrigerating compartment 11, and the heat insulating material 15 is filled between the inner and outer wounds 13 and 14 constituting them to insulate the inside.
또한 냉동실(10)의 후방에 증발기(12)가 설치되어 냉동, 냉장실(10)(11) 내부로 순환되는 냉기가 냉각되고 냉동, 냉장실(10)(11)을 구획하는 격판(16) 내부의 회수 통로(17)를 따라 증발기(12) 쪽으로 재차 순환되면서 냉각된다.In addition, the evaporator 12 is installed at the rear of the freezer compartment 10 so that the cold air circulated into the freezer and refrigerating compartment 10 and 11 is cooled and partitions the freezer and refrigerating compartment 10 and 11. It is cooled while being circulated again toward the evaporator 12 along the recovery passage 17.

The cold air is discharged into the freezing chamber 10 along the discharge port 10a in front of the circulation fan 12a, and some of the cold air is in the freezing chamber 10. It is circulated into the refrigerating chamber 11 along the cold air passage 18 formed integrally with the inner box 13 at the rear. In addition, since the open portion of the cold air passage 18 is covered by a heat insulating plate 19 such as Schiropol, it is not directly exposed toward the evaporator 12, thereby preventing freezing of the passage due to overcooling of the evaporator 12.
또한 냉기통로(18)의 하단과 냉장실(11) 쪽의 내상(13) 상측에 형성된 토출구(11a)가 덕트(20)로 연결된다. 덕트(20)는 격판(16)의 후방을 가로 질러 냉동실(10)과 냉장실(11) 쪽으로 향하는 용기(21)가 구비되고 용기(21)의 개방된 상부를 덮는 커버(22)가 마련된다.In addition, the discharge port 11a formed on the lower end of the cold air passage 18 and on the inner side 13 of the refrigerating chamber 11 side is connected to the duct 20. The duct 20 is provided with a container 21 facing the freezer compartment 10 and the refrigerating compartment 11 across the rear of the diaphragm 16 and provided with a cover 22 covering the open top of the vessel 21.
커버(22)는 냉기통로(18)의 하단과 연결된 입구(24)와 냉장실(11) 쪽의 토출구(l1a)와 연결된 출구(25)가 각각 형성된다. 그리고 용기(2,1)와 커버(22)는 한쪽변이 서로 연결되어 커버(22)가 용기(21) 쪽으로 접어지는 절곡부(23)가 마련된다.The cover 22 has an inlet 24 connected to the lower end of the cold air passage 18 and an outlet 25 connected to the discharge port l1a toward the refrigerating chamber 11, respectively. One side of the container 2, 1 and the cover 22 are connected to each other, and a bent portion 23 in which the cover 22 is folded toward the container 21 is provided.
또한 절곡부(23)를 제외한 커버(22)의 내주면에 돌기(26)가 형성되고 돌기(26)와 대응토록 용기(21)의 상부 내주면에 홈(27)이 형성된다. 그리고 절곡부(23)와 대응되는 커버(22)의 일측변 양측으로 걸림턱(28)이 형성되고 걸림턱(28)과 대응되는 용기(21)의 일측변에 걸림홈(29)이 형성된다.In addition, a protrusion 26 is formed on the inner circumferential surface of the cover 22 except for the bent portion 23, and a groove 27 is formed on the upper inner circumferential surface of the container 21 so as to correspond to the protrusion 26. A locking jaw 28 is formed at both sides of one side of the cover 22 corresponding to the bent portion 23, and a locking groove 29 is formed at one side of the container 21 corresponding to the locking jaw 28. .
이처럼 구성된 본 발명은 커버(22)가 절곡부(23)를 중심으로 접어져 용기(21) 상부에 포개지면 돌기(26)가 홈(27)에 끼워짐과 동시에 서로 결합된다. 이때 포개진 용기(21)와 커버(22)의 각 삼면이 돌기(26)와 홈(27)에 의해 서로 결합되어 밀폐되고 또한 일측면이 절곡부(23)에 의해 연결되어 밀폐됨으로 별도의 밀폐작업이 필요없다.In the present invention configured as described above, when the cover 22 is folded around the bent portion 23 and overlaps the upper portion of the container 21, the protrusions 26 are fitted into the grooves 27 and are coupled to each other. In this case, the three sides of the nested container 21 and the cover 22 are sealed by being combined with each other by the protrusions 26 and the grooves 27, and one side is connected and sealed by the bent portion 23 to separate the seals. No work needed.

That is, the cold air passing through the evaporator 12 is blown toward the discharge port 10a by the circulation fan 12a, and then circulated into the freezer compartment 10, and the stored food is frozen in the process.
또한 냉동실(10) 내부로 순환된 냉기는 격판(16)에 형성된 회수통로(17)를 따라 증발기(12) 쪽으로 재차 순환된다. 그리고 증발기(12)를 거치면서 열교환된 냉기중의 일부가 내상(13) 후방에 형성된 냉기통로(18)쪽으로 송풍된 다음 하단의 덕트(20)를 따라 냉장실(11) 내부로 순환된다.In addition, the cold air circulated into the freezer compartment 10 is circulated again to the evaporator 12 along the recovery passage 17 formed in the diaphragm 16. A portion of the cold air that has been heat-exchanged while passing through the evaporator 12 is blown toward the cold air passage 18 formed behind the inner bed 13 and then circulated into the refrigerating chamber 11 along the lower duct 20.
이때 냉기가 입구(24)를 따라 용기(21) 내부로 유입된 다음 하단의 출구(25)와 토출구(11a)를 통하여 냉장실(11) 내부로 순환되고 냉장실(11) 내부의 보관중인 음식이 일정온도로 냉장된다. 또한 냉장시킨 냉기는 격판(16)에 형성된 회수통로(17)를 따라 증발기(12) 쪽으로 재순환된다.At this time, the cold air is introduced into the container 21 along the inlet 24 and then circulated into the refrigerating chamber 11 through the outlet 25 and the discharge port 11a at the lower end, and the food stored in the refrigerating chamber 11 is constant. Refrigerated to temperature In addition, the refrigerated cold air is recycled toward the evaporator 12 along the recovery passage 17 formed in the diaphragm 16.
이상에서와 같이 본 발명에 따르면 냉동실 후방에 형성된 냉기통로와 냉장실 내부의 토출구를 연결하는 덕트를 구성함에 있어서, 용기와 커버의 한쪽변이 절곡부에 의해 서로 연결되어 접어지도록 하고 나머지 삼변에 돌기와 홈을 각각 형성함으로서, 커버를 용기에 포개면 돌기와 홈의 결합에 의해 삼변이 밀폐되고 나머지 한 변이 절곡부에 의해 밀폐됨으로 별도의 밀폐작업이 불필요한 등의 효과가 있다.As described above, according to the present invention, when configuring a duct connecting the cold air passage formed in the rear of the freezer compartment and the discharge port inside the refrigerating compartment, one side of the container and the cover are connected to each other by the bent portion, and the protrusions and grooves are formed on the remaining three sides. By forming each cover, the three sides are sealed by the combination of the projection and the groove when the cover is superimposed on the container, and the other side is closed by the bent portion, so that there is no need for a separate sealing operation.
