Description

냉장고의 냉기분배덕트 결빙방지구조Cold air distribution duct freezing prevention structure of refrigerator

본 고안은 냉장고의 인너 케이스와 아우터 케이스의 사이 및 냉장고 도어에 매입되는 냉기분배덕트가 냉장고 도어의 오픈시 외부공기에 의해 결빙되는 것을 방지하기 위한 냉장고의 냉기분배덕트 결빙방지구조에 관한 것으로, 특히 냉장고 본체의 내부에 둘러쳐져 있는 방로파이프의 일부가 상기 냉기분배덕트를 감싸도록하여 그 열로 냉기분배덕트 주위의 결빙을 방지하는 냉장고의 냉기분배덕트 결빙방지구조에 관한 것이다.The present invention relates to a cold air distribution duct freezing prevention structure of the refrigerator for preventing the cold air distribution duct embedded between the inner case and the outer case of the refrigerator and the refrigerator door from being frozen by external air when the refrigerator door is opened. It relates to a cold air distribution duct freezing structure of the refrigerator so that a portion of the airway pipe enclosed inside the refrigerator main body surrounds the cold air distribution duct to prevent freezing around the cold air distribution duct with its heat.

일반적인 냉장고의 냉기덕트는 냉동실 및 냉장실의 후벽측에 형성되어 전방측으로 냉기를 뿜어내거나 또는 상기 냉기덕트의 냉기토출구에 배기공이 구비된 덕트선반을 끼워 그 배기공으로 냉기를 배출시키는 형태가 주로 사용되어 왔다. 그러나, 점차 냉장고가 대형화되면서는 상기의 냉기덕트에 의해 공급되는 냉기만으로 냉장실 전체를 균일하게 냉각시킬 수 없게 됨에 따라 상기 냉기덕트에서 냉기분배덕트를 분관시켜 인너 케이스의 외측벽을 통하여 냉장실 도어로 냉기를 직접 공급하도록 하고 있다.The cold air duct of a general refrigerator is formed on the rear wall side of the freezer compartment and the refrigerating compartment to emit cold air to the front side or to insert a duct shelf equipped with an exhaust hole at the cold air discharge outlet of the cold air duct to discharge the cold air into the exhaust hole. . However, as the refrigerator gradually increases in size, the entire refrigerating compartment cannot be uniformly cooled by only the cold air supplied by the cold air duct, so that the cold air duct is separated from the cold air duct to the cold room door through the outer wall of the inner case. Direct supply.

한편, 상기 냉장고 본체의 전면(前面)부에는 응축기로부터 분출되는 고온의 냉매가스가 통과하는 방로파이프가 둘러쳐져 고온 다습시 냉장고의 옆면에 이슬이 발생되는 것을 방지하도록 하고 있다.On the other hand, the front part of the refrigerator main body is surrounded by a passage pipe through which the high-temperature refrigerant gas ejected from the condenser passes to prevent dew from occurring on the side of the refrigerator during high temperature and high humidity.

도 1은 이러한 종래 냉장고의 구성을 개략적으로 보인 사시도로서 이에 도시된 바와 같이, 냉장고는 통상 압축기(1), 응축기(2), 모세관(3) 그리고 증발기(4)가 차례대로 연통되어 있고, 상기 증발기(4)의 출구는 다시 압축기(1)의 입구와 연통되는 일반적인 냉동사이클로 구성되어 있다.1 is a perspective view schematically showing the configuration of such a conventional refrigerator, as shown in the refrigerator, in which a compressor 1, a condenser 2, a capillary tube 3, and an evaporator 4 are sequentially communicated. The outlet of the evaporator 4 again consists of a general refrigeration cycle in communication with the inlet of the compressor 1.

이와 같이 구성된 냉장고에 있어서, 상기 응축기(2)에는 냉장고 옆면에 이슬이 맺히는 것을 방지하기 위한 방로파이프(7)의 입구부가 연통되어 있고, 그 방로파이프(7)의 출구부는 증발기(4)의 입구부에 연통되도록 냉장고 본체의 전면(前面)에 둘러쳐져 있다.In the refrigerator configured as described above, the condenser 2 communicates with the inlet of the drip pipe 7 for preventing dew from forming on the side of the fridge, and the outlet of the drip pipe 7 is the inlet of the evaporator 4. It is surrounded by the front surface of the refrigerator main body so as to communicate with the part.

한편, 상기 증발기(4)의 하측에는 도 2a에 도시된 바와 같이, 냉기덕트(8)가 설치되어 증발기(4)로부터 생성되는 냉기를 냉장실로 유도하도록 되어 있는 한편 상기 냉기덕트(8)의 일측에는 냉기분배덕트(9)가 분관되어 냉장실 인너 케이스(10)의 외벽측에 매입되고, 그 냉기분배덕트(9)의 단부와 대향되는 냉장실 도어(11)의 내측에는 다수개의 배기공(12a)이 형성된 냉기토출덕트(12)가 매입되어 있다.Meanwhile, as shown in FIG. 2A, a cold air duct 8 is installed below the evaporator 4 to guide cold air generated from the evaporator 4 to the refrigerating chamber, while one side of the cold air duct 8 is provided. The cold air distribution duct 9 is piped into the outer wall side of the refrigerating compartment inner case 10, and a plurality of exhaust holes 12a are provided inside the refrigerating compartment door 11 facing the end of the cold air distribution duct 9. The formed cold air discharge duct 12 is embedded.

도면중 미설명 부호인 5는 건조기, 6은 어큐뮬레이터, 8a는 냉기토출구, 11a는 가스킷이다.In the drawings, reference numeral 5 denotes a dryer, 6 an accumulator, 8a a cold air discharge port, and 11a a gasket.

상기와 같이 구성된 종래의 냉장고에 있어서의 냉기의 흐름은 다음과 같다.The flow of cold air in the conventional refrigerator configured as described above is as follows.

즉, 상기 증발기(4)에 의해 발생된 냉기의 일부가 냉기덕트(8)를 타고 흘러내려 냉기토출구(8a)를 통해 냉장실의 고내로 분출되는 한편 상기 냉기의 일부는 냉기덕트(8)에서 냉기분배덕트(9) 및 냉기토출덕트(12)으로 유입되어 그 냉기토출덕트(12)에 형성된 각 배기공(12a)을 통해 냉장고의 고내로 분출되는 것이었다.That is, a portion of the cold air generated by the evaporator 4 flows down the cold air duct 8 and is ejected into the refrigerator compartment through the cold air discharge port 8a while a part of the cold air is cold air in the cold air duct 8. It flowed into the distribution duct 9 and the cold air discharge duct 12, and was blown into the inside of the refrigerator through each exhaust hole 12a formed in the cold air discharge duct 12.

여기서, 상기 냉장고 도어(11)의 가장자리에는 가스킷(11a)이 압입되어 상기 냉기분배덕트(9)와 냉기토출덕트(12)의 연결부위를 통과하는 냉기가 새지않도록 하고 있다.Here, the gasket 11a is press-fitted to the edge of the refrigerator door 11 to prevent leakage of cold air passing through the connection portion between the cold air distribution duct 9 and the cold air discharge duct 12.

한편, 상기 응축기(2)에서 방로파이프(7)로 유입되는 고온의 냉기는 상기 방로파이프(7)를 따라 냉장고 전면(前面)을 순회하면서 외부의 더운공기가 고내의 찬 냉기와 부딪히면서 냉장고의 옆면에 이슬방울이 맺히는 것을 방지하도록 되는 것이었다.On the other hand, the hot air flowing into the conduit pipe 7 from the condenser 2 circulates through the front surface of the refrigerator along the conduit pipe 7 while the outside hot air collides with the cold condenser inside the refrigerator. It was to prevent dewdrops from forming.

그러나, 종래의 냉장고에 있어서 냉장고 도어를 오픈하는 경우에는 도 2b에 도시된 바와 같이, 외부의 더운공기(실선으로 표시)가 열려진 쪽이나 또는 가스킷(11a)이 벌어지면서 형성된 틈새를 통해 고내로 유입되어 찬 공기과 부딪히면서 인너 케이스의 벽면에 물방울이 맺히게 되고, 그 물방울이 결빙되면서 냉기분배덕트(9)의 내측으로 성장하여 상기 냉기분배덕트(9)를 막게 되며, 그 막힌 냉기분배덕트(9)에 의해 냉동효율이 저하되거나 또는 이를 극복하기 위하여 냉장고를 강하게 동작시킴에 따라 전력낭비가 뒤따르게 되는 문제점이 있었다.However, in the conventional refrigerator, when the refrigerator door is opened, as shown in FIG. 2B, the outside hot air (indicated by a solid line) is opened or flows into the inside of the gap through a gap formed by the gasket 11a. Water droplets form on the wall of the inner case while colliding with cold air, and the water droplets freeze to grow inside the cold air distribution duct 9 to block the cold air distribution duct 9, and by the blocked cold air distribution duct 9. As the refrigeration efficiency is lowered or the refrigerator is strongly operated to overcome this problem, power consumption is followed.

따라서, 본 고안은 냉장고의 오픈시에도 상기 냉기토출덕트와 연결되는 냉기분배덕트 주위에 물방울이 맺히는 것을 방지함으로써, 냉장고의 냉동효율의 향상은 물론 이를 통해 전력낭비를 절감시킬 수 있는 냉장고의 냉기분배덕트 결빙방지구조를 제공하는데 그 목적이 있다.Therefore, the present invention prevents water droplets from forming around the cold air distribution duct connected to the cold air discharge duct even when the refrigerator is opened, thereby improving the freezing efficiency of the refrigerator and thereby reducing power consumption. Its purpose is to provide a duct freeze protection structure.
