Description
본 발명은 냉장고의 냉기 순환장치에 관한 것으로, 더욱 상세하게는 저장실 내부의 냉기를 순환시키는 순환팬의 구조에 관한 것이다.The present invention relates to a cold air circulation device of a refrigerator, and more particularly, to a structure of a circulation fan for circulating cold air inside a storage compartment.

이러한 종래의 냉장고는 도 1에 도시된 바와 같이, 본체(1)의 내부에 저장물이 저장되는 저장실(2)이 형성되고, 이 저장실(2)의 전면 개구부에는 저장실(2)을 개폐하는 도어(3)가 설치되어 있다.In the conventional refrigerator, as illustrated in FIG. 1, a storage compartment 2 in which a storage is stored is formed in the main body 1, and a door for opening and closing the storage compartment 2 in the front opening of the storage compartment 2. (3) is installed.
또한, 저장실(2)의 내측에 위치되는 후면 벽체에는 냉기를 생성하는 증발기(4)가 설치되어 있고, 증발기(4)의 상측에는 증발기를 거치면서 열교환이 된 냉기를 저장실(2)의 내부로 강제 순환시키는 순환팬(5)이 설치되어 있으며, 이 순환팬(5)에 의하여 강제 송풍되는 냉기의 흐름을 안내하는 냉기 안내덕트(6)가 형성되어 있다. 또한, 냉기 안내덕트(6)의 흡입유로에는 냉기흡입구(8)가 형성되고, 토출유로에는 다수의 냉기 토출구(9)가 형성되어 있다.In addition, an evaporator 4 for generating cold air is provided on the rear wall located inside the storage compartment 2, and the cold air that has undergone heat exchange while passing through the evaporator is installed inside the storage compartment 2 above the evaporator 4. A circulation fan 5 for forced circulation is provided, and a cold air guide duct 6 for guiding the flow of cold air forcedly blown by the circulation fan 5 is formed. In addition, a cold air suction port 8 is formed in the suction flow path of the cold air guide duct 6, and a plurality of cold air discharge ports 9 are formed in the discharge flow path.
이와 같이 구성된 종래 냉장고는 순환팬(5)이 구동되면, 저장실(2) 내부의 냉기가 냉기 안내덕트의 냉기 흡입구(8)를 통해 증발기(4) 쪽으로 유입되어 증발기(4)와 열교환을 한 후, 순환팬(5)의 송풍력에 의해 냉기 토출구(9)를 통해 다시 저장실(2)로 공급되는 과정이 반복되면서 냉기의 순환이 이루어지게 된다.In the conventional refrigerator configured as described above, when the circulation fan 5 is driven, cold air inside the storage compartment 2 flows into the evaporator 4 through the cold air inlet 8 of the cold air guide duct to exchange heat with the evaporator 4. The circulation of the cold air is made by repeating the process of supplying the cold air to the storage chamber 2 again through the cold air discharge port 9 by the blowing force of the circulation fan 5.
그러나, 이러한 종래 냉장고의 냉기 순환장치는 저장실(2)과 증발기(4)를 순회하는 냉기가 후면벽의 냉기 토출구(9)를 통해 토출이 되어, 저장실(2)의 특정부에 형성된 냉기흡입구(8)로 흡입이 되기 때문에, 저장실(2) 내부의 냉기 순환이 원활하지 못하여 저장실(2)의 냉각효율이 떨어지는 문제가 있었다.However, in the conventional cold air circulation device of the refrigerator, cold air circulating through the storage chamber 2 and the evaporator 4 is discharged through the cold air discharge port 9 of the rear wall, and thus the cold air suction port formed in the specific part of the storage chamber 2 ( 8), since the cold air circulation inside the storage compartment 2 is not smooth, the cooling efficiency of the storage compartment 2 is lowered.
즉, 냉기토출구(9)의 위치와 냉기흡입구(8)의 위치가 정해져 있기 때문에 이들과 인접되는 주위에는 냉기의 순환이 원활하게 이루어지지만, 이들과 멀리 떨어진 저장실(2)의 구석부분 등에는 냉기의 순환이 원활하지 못하게 되어 저장실(2) 내부의 온도편차가 큰 문제가 있었다.That is, since the location of the cold air discharge port 9 and the location of the cold air suction port 8 are determined, the circulation of cold air is smoothly performed in the vicinity adjacent to the cold air discharge port, but the cold air is stored in the corner portion of the storage compartment 2 far from these. There was a problem that the temperature of the inside of the storage compartment (2) is not large because the circulation of the smooth.

구동모터가 회전되어 순환팬(30)의 제 1날개부(32)가 구동되면, 저장실(11)의 냉기는 냉기 안내덕트(19)의 냉기흡입구(21)를 통해 증발기(16)가 설치된 냉각실(17)로 유입되고, 냉각실로 유입된 냉기는 증발기(16)와 열교환을 하면서, 더 차가운 냉기로 변하게 된다.When the driving motor is rotated to drive the first blade part 32 of the circulation fan 30, the cold air in the storage compartment 11 is cooled by the evaporator 16 installed through the cold air inlet 21 of the cold air guide duct 19. The cold air introduced into the chamber 17 and introduced into the cooling chamber undergoes heat exchange with the evaporator 16 and is converted into cooler cold.
즉, 증발기(16)에서 열교환이 된 냉기는 제 1날개부(32)를 거쳐 냉기 안내덕트(19)를 따라 흐르게 되고, 냉기토출구(20)를 통해 다시 저장실(11)로 토출이됨으로써 냉기의 순환이 이루어지게 된다.That is, the cold air that has been heat-exchanged in the evaporator 16 flows along the cold air duct 19 through the first blade part 32, and is discharged back into the storage chamber 11 through the cold air outlet 20. There is a circulation.
이와 동시에, 제 1날개부(32)와 함께 회전되는 제 2날개부(33) 쪽에는 저장실(11) 내부의 냉기가 보호커버(40)의 중앙부에 형성된 관통공(42)을 통해 제 2날개부(33)로 유입되고, 제 2날개부(33)의 외주 방향으로 소용돌이를 일으키며 분출된다. 이때, 분출되는 냉기는 저장실(11) 내부에 와류를 발생시킴으로써 저장실의 냉기 분포를 고르게 한다.At the same time, the second wing portion 33 is rotated together with the first wing portion 32, the cold air inside the storage compartment 11 through the through hole 42 formed in the center of the protective cover 40, the second wing It flows into the part 33 and blows out in a vortex in the circumferential direction of the 2nd wing part 33. At this time, the ejected cold air evenly distributes the cold air distribution in the storage compartment by generating a vortex inside the storage compartment 11.
한편, 제 2날개부(33)의 전면에 설치된 보호커버(40)는 투명부재로 마련되어 있기 때문에 사용자가 순환팬의 순환동작을 확인할 수 있게 되는데, 본 발명에 따른 냉기 순환장치는 보호커버(40)의 내면에서 계속 냉기가 순환되어 흐르기 때문에, 다습한 냉기가 순환된다 하더라도 보호커버(40)에 이슬맺힘 현상이 발생되지 않아 보호커버(40)가 항상 투명한 상태로 유지되게 된다.On the other hand, since the protective cover 40 installed on the front of the second wing 33 is provided with a transparent member, the user can check the circulation operation of the circulation fan, the cold air circulation device according to the present invention is a protective cover 40 Since the cold air continues to circulate in the inner surface of the c), even if humid cold air is circulated, dew does not occur in the protective cover 40 so that the protective cover 40 is always kept in a transparent state.
이처럼, 본 발명에 따른 냉기 순환장치는 제 1날개부(32)와 제 2날개부(33)가 일체로 형성된 순환팬(30)이 구비됨으로써 냉기 안내덕트(19)의 냉기순환뿐만 아니라, 제 2날개부(33)에 의해 내동실 또는 냉장실에 와류가 발생되어 내부의 냉기분포가 고르게 유지된다. 또, 제 2날개부(33)를 덮는 보호커버(40)가 투명부재로 마련됨으로써 사용자가 순환팬의 회전동작을 육안으로 확인할 수 있게 되어, 제품에 대한 신뢰성이 높아지게 된다.As described above, the cold air circulation device according to the present invention is provided with a circulation fan 30 in which the first wing part 32 and the second wing part 33 are integrally formed, as well as the cold air circulation of the cold air duct 19. Vortex is generated in the inner cavity chamber or the refrigerating chamber by the two wing portions 33, thereby maintaining the distribution of cold air evenly. In addition, since the protective cover 40 covering the second blade part 33 is provided as a transparent member, the user can visually check the rotation operation of the circulation fan, thereby increasing the reliability of the product.
이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고의 냉기 순환장치는 냉기를 순환시키는 순환팬이 회전판의 양측면에 날개부가 형성된 원심팬으로구성되며, 이 날개부는 상기 회전판의 내측면에 형성되어 냉기 안내덕트의 내측에 위치되는 제 1날개부와, 저장실 쪽으로 노출이 되는 제 2날개부로 구성되었다. 또한, 제 2날개부의 전면에는 제 2날개부를 보호하도록 중앙에 관통공이 형성된 보호커버가 설치되며, 이 보호커버는 투명부재로 마련되었다. 따라서, 제 2날개부의 구동에 의해 저장실 내부에 와류가 발생되어 저장실의 냉기 분포가 고르게 유지될 수 있을 뿐만 아니라, 사용자가 제 2날개부의 회전동작을 육안으로 확인할 수 있게 되어 제품에 대한 신뢰성이 높아지는 효과가 있다.As described in detail above, the cold air circulation device of the refrigerator according to the present invention is composed of a centrifugal fan in which a circulation fan for circulating cold air is formed on both sides of the rotating plate, and the wing is formed on the inner side of the rotating plate to guide the cold air. The first wing part located inside the duct and the second wing part exposed to the storage compartment. In addition, a protective cover having a through hole formed in the center thereof is installed on the front surface of the second wing to protect the second wing, and the protective cover is made of a transparent member. Therefore, the vortex is generated inside the storage chamber by the driving of the second blade unit, so that the distribution of cold air in the storage chamber can be maintained evenly, and the user can visually check the rotation operation of the second blade unit, thereby increasing the reliability of the product.
