Description
본 고안은 냉장고의 냉기유로 연결구조에 관한 것으로, 더욱 상세하게는 냉동실의 냉기유로로부터 냉장실 냉기유로로 연결되는 연결부의 구조를 개선하여 냉기의 흐름이 원활하도록 한 냉장고의 냉기유로 연결구조에 관한 것이다.The present invention relates to a cold air flow path connecting structure of the refrigerator, and more particularly to a cold air flow path connecting structure of the refrigerator to improve the structure of the connection portion connected from the cold air flow path of the freezer compartment to the cold room cold flow path to facilitate the flow of cold air. .
일반적으로 냉장고는 밀폐된 저장실 이면에 냉기를 생성하는 증발기가 설치되고, 저장실의 냉기가 증발기 주위를 순회하면서 냉각되도록 하여 저장실이 차가운 상태로 유지될 수 있게 한 장치이다.In general, a refrigerator is installed on the back of a sealed storage compartment, and an evaporator for generating cold air is installed, and the cold compartment of the storage compartment is cooled while circulating around the evaporator so that the storage compartment can be kept cold.
이러한 냉장고는 도 1에 도시된 바와 같이, 상부의 냉동실(2)과 하부의 냉장실(3)이 중간벽(4)에 의해 구획되며, 냉동실(2)과 냉장실(3)의 개방된 전면에는 개폐 가능한 도어(5a,5b)가 설치되어 있다. 냉동실(2)의 내측 후방에는 냉기를 생성하는 증발기(6)가 설치되어 있으며, 증발기(6)의 상부에는 냉동실(2)과 냉장실(3)의 내부공기를 강제 순환시키는 냉기순환팬(7)이 설치되어 있다.In the refrigerator, as illustrated in FIG. 1, the upper freezing compartment 2 and the lower refrigerating compartment 3 are partitioned by an intermediate wall 4, and the refrigerator is opened and closed at an open front surface of the freezing compartment 2 and the refrigerating compartment 3. Possible doors 5a and 5b are provided. An evaporator 6 for generating cold air is provided at an inner rear side of the freezer compartment 2, and a cold air circulation fan 7 for forcibly circulating internal air of the freezer compartment 2 and the refrigerating compartment 3 above the evaporator 6. Is installed.
또 냉동실(2)의 내측에는 냉동실(2)의 내부공간과 증발기(6)가 설치된 공간을 구획하는 내측판(8)이 설치되고, 내측판(8)에는 다수의 냉기토출구(8a)가 형성되어 있으며, 내측판(8)의 이면에는 냉기공급유로(9)를 형성하는 냉기덕트(10)가 설치되어 있다. 또한 냉장실(3)의 내측 후방에도 다수의 냉기토출구(11a)를 갖는 내측판(11)에 의해 냉기공급유로(12)가 형성되는데, 이 냉장실측 냉기공급유로(12)는 중간벽(4)의 연결통로(13)를 통해 냉동실측 냉기공급유로(9)와 연통되어 있다. 이때 냉동실측 냉기덕트(10)의 하단에는 중간벽(4)의 연결통로(13)와 냉동실측 냉기공급유로(9)가 연통되도록 관통공(10a)이 형성되어 있다.Inside the freezer compartment 2, an inner plate 8 is provided which partitions the interior space of the freezer compartment 2 and the space in which the evaporator 6 is installed, and a plurality of cold air outlets 8a are formed in the inner plate 8. On the back surface of the inner plate 8, a cold air duct 10 for forming a cold air supply passage 9 is provided. In addition, a cold air supply passage 12 is formed by an inner side plate 11 having a plurality of cold air outlets 11a on the inner rear side of the refrigerating compartment 3, and the cold air supply passage 12 of the refrigerating compartment side is an intermediate wall 4. It is in communication with the freezer compartment side cold air supply passage (9) through the connecting passage (13). At this time, the through hole 10a is formed at the lower end of the freezing compartment side cold air duct 10 so that the connection passage 13 of the intermediate wall 4 and the freezing compartment side cold air supply passage 9 communicate with each other.
그런데, 이와 같이 구성된 종래 냉장고는 냉동실(2)의 내부에 냉기덕트(10)를 조립하는 과정에서 작업자의 실수 등으로 냉기덕트(10)의 오조립이 발생될 경우, 냉기덕트(10) 하단의 관통공(10a)과 중간벽(4)의 연결통로(13)가 어긋나게 되어 냉기의 흐름이 원활하지 못한 문제가 있었다. 즉, 도 2에 도시된 바와 같이, 냉기덕트(10)의 관통공(10a)이 일방향(A방향)으로 치우치게 조립될 경우, 냉기덕트(10)의 관통공(10a)과 연결통로(13)의 입구가 일부 겹쳐서 유로의 단면적이 작아지게 되는데, 이는 냉장실(3)의 냉기공급을 원활하지 못하게 할 뿐만 아니라 냉기의 유동소음을 유발하는 원인이 되었다.By the way, in the conventional refrigerator configured as described above, when misassembly of the cold air duct 10 occurs due to an operator's mistake in the process of assembling the cold air duct 10 in the freezer compartment 2, the lower portion of the cold air duct 10 The connection passage 13 between the through hole 10a and the intermediate wall 4 is displaced, which causes a problem that the flow of cold air is not smooth. That is, as shown in Figure 2, when the through-hole 10a of the cold air duct 10 is assembled in one direction (A direction), the through hole (10a) and the connecting passage 13 of the cold air duct 10 The cross section of the flow path becomes small due to overlapping the inlet of, which not only causes the cold air supply of the refrigerating chamber 3 to be smooth, but also causes the flow noise of the cold air.
본 고안은 이와 같은 문제점을 해결하기 위한 것으로, 본 고안의 목적은 냉기덕트의 관통공과 연결통로의 오조립을 방지하여 냉장실로 공급되는 냉기의 흐름이 원활하도록 할 뿐만 아니라 냉기의 유동소음을 방지는 냉장고의 냉기유로 연결구조를 제공하는 것이다.The present invention is to solve such a problem, the purpose of the present invention is to prevent the assembling of the through-hole and the connection passage of the cold air duct not only to smooth the flow of cold air supplied to the refrigerating chamber, but also to prevent the flow noise of cold air The cold air of the refrigerator provides a connection structure.

냉장실(22)에는 냉동실측 냉기공급유로(28)와 연계되는 냉장실측 냉기공급유로(30)를 형성하도록 내측 후방에 내측판(31)이 설치되며, 이 내측판(31)에는 다수의 냉기토출구(31a)가 형성된다. 또한, 냉동실(21)과 냉장실(22)을 구획하는 중간벽(32)에는 냉동실측 냉기공급유로(28)와 냉장실측 냉기공급유로(30)를 연통시키는 연결통로(33)가 형성되며, 냉동실측 냉기덕트(29)의 하단에는 중간벽(32)의 연결통로(33)로 냉기가 흐르도록 관통공(29a)이 형성된다. 그리고 중간벽(32)에는 냉동실(21)과 냉장실(22)로 공급된 냉기가 다시 증발기(25) 쪽으로 복귀하도록 하는 복귀유로(34)가 형성된다.The refrigerating chamber 22 is provided with an inner side plate 31 at the inner rear side to form a refrigerating chamber side cold air supply passage 30 associated with the freezer compartment side cold air supply passage 28, and the inner side plate 31 has a plurality of cold air discharge outlets. 31a is formed. In addition, the intermediate wall 32 partitioning the freezing compartment 21 and the refrigerating compartment 22 is provided with a connecting passage 33 for communicating the freezing compartment side cold air supply passage 28 and the refrigerating compartment side cold air supply passage 30. The through hole 29a is formed at the lower end of the measured cold air duct 29 so that cold air flows through the connection passage 33 of the intermediate wall 32. In addition, a return passage 34 is formed in the intermediate wall 32 to allow the cold air supplied to the freezing chamber 21 and the refrigerating chamber 22 to return to the evaporator 25 again.
이때 본 고안에 따른 냉장고는 냉동실(21) 내부에 장착되는 냉기덕트(29)의 관통공(29a)과 중간벽(32)의 연결통로(33)의 오조립을 방지하여 냉장실(22)측으로 흘러가는 냉기의 흐름이 원활하도록 한 것이다.In this case, the refrigerator according to the present invention prevents misassembly of the through hole 29a of the cold air duct 29 mounted in the freezing compartment 21 and the connection passage 33 of the intermediate wall 32, and flows toward the refrigerating chamber 22 side. It is to make the flow of cold air smooth.
도 4와 도 5는 이러한 구성을 위한 것으로 냉기덕트(29) 하단의 관통공(29a)과 중간벽(32)에 형성된 연결통로(33)의 연결구조를 도시한 것이다. 이를 참조하면, 냉기덕트(29)의 관통공(29a) 둘레에는 연결통로(33)의 내부로 진입되어서 걸리도록 하측으로 연장된 제1걸림턱(35)이 형성된다. 이때 제1걸림턱(35)은 그 외면이 연결통로(33)의 입구측 내면에 밀착 지지되도록 사각의 상자형태로 제작되며, 하면과 전면이 개방되어서 냉기의 흐름이 원활하도록 구성된다. 또한, 제1걸림턱(35)은 제1걸림턱(35)이 연결통로(33)의 내부로 진입할 때 용이하게 끼워질 수 있도록 개방된 쪽의 양측면 단부(35a)가 빗면으로 구성된다.4 and 5 illustrate a connection structure of the connection passage 33 formed in the through hole 29a and the intermediate wall 32 at the bottom of the cold air duct 29 for such a configuration. Referring to this, around the through hole 29a of the cold air duct 29, a first catching jaw 35 extending downward is formed so as to enter the interior of the connection passage 33 and be caught. At this time, the first catching jaw 35 is manufactured in the form of a square box so that its outer surface is tightly supported on the inner side of the inlet side of the connection passage 33, and is configured to smoothly flow the cold air by opening the lower surface and the front surface. In addition, the first catching jaw 35 has both side end portions 35a of the open side so as to be easily fitted when the first catching jaw 35 enters the inside of the connection passage 33, and is composed of a slanted surface.
이와 같은 구성은 냉동실(21) 내부에 냉기덕트(29)를 장착할 때 관통공(29a) 둘레의 제1걸림턱(35)이 연결통로(33)의 내부로 진입되어 걸림으로써, 관통공(29a)과 연결통로(33)가 정확히 일치된 상태로 조립될 수 있게 한 것이다.In this configuration, when the cold air duct 29 is mounted in the freezing chamber 21, the first catching jaw 35 around the through hole 29a enters into the connection passage 33 and is caught therein. 29a) and the connecting passage 33 is to be assembled in a state exactly matched.
한편, 도 6은 이러한 기술사상을 기본으로 한 본 고안의 다른 실시 예를 도시한 것으로, 연결통로(33)의 입구 둘레에서 상방향으로 돌출하도록 구성된 제2걸림턱(36)을 구비하여, 제2걸림턱(36)이 관통공(29a)에 끼워져서 걸리도록 한 것이다. 즉, 냉기턱트(29)를 장착할 때 연결통로(33)의 둘레에서 돌출한 제2걸림턱(36) 외면에 관통공(29a)의 내면이 끼워져서 걸리도록 함으로써 관통공(29a)과 연결통로(33)의 중심이 일치하도록 한 것이다.On the other hand, Figure 6 shows another embodiment of the present invention based on the technical concept, having a second locking jaw 36 configured to protrude upward from the periphery of the inlet of the connecting passage 33, The catching jaw 36 is fitted to the through hole 29a to be caught. That is, the inner surface of the through hole 29a is fitted to the outer surface of the second catching jaw 36 protruding from the circumference of the connecting passage 33 when the cold air duct 29 is mounted, thereby connecting with the through hole 29a. The center of the passage 33 is to match.
다음은 이와 같이 구성된 본 고안에 따른 냉장고의 동작을 설명한다.Next will be described the operation of the refrigerator according to the present invention configured as described above.
냉동실(21) 후방의 냉기순환팬(26)이 구동되면, 증발기(25)를 거치면서 냉각된 냉기가 냉동실측 냉기공급유로(28)로 공급되고, 냉기공급유로(28)의 냉기는 내측판(27)의 냉기토출구(27a)를 통해 냉동실(21) 내부로 공급된다. 또한 냉동실측 냉기공급유로(28)의 냉기 일부는 냉기덕트(29) 하단의 관통공(29a)과 연결통로(33)를 통해 냉장실측 냉기공급유로(30)로 흘러서 냉장실(22)의 냉기토출구(31a)를 통해 냉장실(22) 내부로 공급된다. 그리고 냉동실(21)과 냉장실(22)의 내부공기는 다시 중간벽(32)의 복귀유로(34)를 통해 증발기(25) 쪽으로 복귀하면서 계속 순환된다.When the cold air circulation fan 26 behind the freezing chamber 21 is driven, cold air cooled while passing through the evaporator 25 is supplied to the cold air supply passage 28 on the freezer compartment, and the cold air of the cold air supply passage 28 is located on the inner plate. It is supplied into the freezing chamber 21 through the cold air discharge port 27a of (27). In addition, a part of the cold air in the freezer compartment cold air supply passage 28 flows into the cold compartment supply cold air supply passage 30 through the through hole 29a and the connection passage 33 at the bottom of the cold air duct 29, and thus the cold air outlet of the cold compartment 22 It is supplied into the refrigerating chamber 22 through 31a. The internal air of the freezing compartment 21 and the refrigerating compartment 22 continues to circulate while returning to the evaporator 25 through the return passage 34 of the intermediate wall 32 again.
이때 본 고안에 따른 냉장고는 냉기덕트(29) 하단의 관통공(29a)이 걸림턱(35,36)에 의해 연결통로(33)와 정확히 일치하기 때문에, 냉동실측 냉기공급유로(28)에서 냉장실(22)로 흐르는 냉기의 흐름이 원활해지고, 유체의 유동소음이 줄어들어 정숙한 운전이 가능해진다.At this time, the refrigerator according to the present invention is because the through-hole 29a at the bottom of the cold air duct 29 is exactly the same as the connection passage 33 by the locking projections 35 and 36, so that the refrigerator compartment in the freezer compartment side cold air supply passage 28 The flow of cold air flowing to (22) is smooth, and the flow noise of the fluid is reduced, so that a quiet operation is possible.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 냉장고의 냉기유로 연결구조는 냉기덕트의 관통공과 중간벽의 연결통로가 연결되는 연결부에 오조립방지를 위한 걸림턱이 마련되어 냉기덕트를 조립할 때 관통공의 중심과 연결통로의 중심이 항상 일치하여 조립됨으로써, 냉동실측 냉기공급유로에서 냉장실측으로 흐르는 냉기의 흐름이 원활해지는 효과가 있다.As described in detail above, the cold air flow path connecting structure of the refrigerator according to the present invention is provided with a locking step for preventing misassembly of the through hole when the through hole of the cold air duct and the connecting passage of the intermediate wall is connected to the through hole when assembling the cold air duct. Since the center and the center of the connecting passage are always coincident with each other, there is an effect that the flow of cold air flowing from the freezing chamber side cold air supply passage to the refrigerating chamber side becomes smooth.
또한, 이처럼 냉기의 흐름이 원활해짐으로써 냉기의 유동소음이 줄어드는 효과가 있다.In addition, the smooth flow of cold air as described above has the effect of reducing the flow noise of cold air.
