It is arranged in a state so that the cold air passing through the passage of the cold and cold air located in the storage spaces (R1, R2, R3, R4) 33 is made to conduct heat transfer by conduction.
상기 칸막이(10)의 상부에는 상기 냉동실(R)에서 증발기(20)를 통한 냉기가 송풍기(26)에 의해 냉장실(R)의 냉기 분배기(34) 측으로 토출될 수 있도록 냉기 토출덕트(12)가 형성되고, 상기 칸막이(10)의 하부에는 상기 냉장실(R)을 지나면서 각각의 선반(32a,32b,32c,32d)에 올려진 음식물을 낮은 온도상태에서 냉장시키는 냉기가 냉동실(F)로 흡입될 수 있도록 냉기 흡입덕트(14)가 형성된다.A cold air discharge duct 12 is provided at the upper part of the partition 10 so that cool air from the freezer compartment R through the evaporator 20 may be discharged to the cold air distributor 34 of the refrigerating compartment R by the blower 26.

한편, 상기 냉장고는 상기 증발기(20)를 통한 냉매를 저온저압의 기체상태의 냉매를 압축하여 고온고압의 기체상태로 만들기 위해 냉장고의 기계실(미도시)에 설치된 압축기(미도시)와, 상기 압축기에서 나오는 기체냉매를 고압의 액체상태로 응축되면서 냉매가 지닌 열을 외부로 방출하는 응축기(미도시)와, 상기 응축기를 거친 고압의 액체상태의 냉매를 감압시키는 모세관(미도시)을 포함하는 냉동사이클이 설치된다.The refrigerator may include a compressor (not shown) installed in a machine room (not shown) of the refrigerator to compress the refrigerant through the evaporator 20 into a gaseous state of high temperature and high pressure by compressing a refrigerant of low temperature and low pressure gaseous state, and the compressor.

상기와 같이 구성된 종래 기술의 동작을 살펴보면 다음과 같다.Looking at the operation of the prior art configured as described above are as follows.
먼저, 냉동사이클의 구동에 의해 상기 증발기(20)에는 저온저압의 냉매가 흐르게 되고, 냉동실(F) 내의 공기는 증발기(20)를 표면을 지나면서 저온의 냉매와 열교환되어 저온의 냉기로 변화되며, 이 냉기는 냉동실(F)에 저장된 음식물을 영하의 저온 상태로 유지시키면서 상기 송풍팬(26)에 의해 압송되어 상기 칸막이(10)의 냉기 토출덕트(12)로 유입된다. 그리고, 상기 냉기 토출덕트(12)를 통한 냉매는 냉매 분배기(34)에 의해 냉장실(R) 내의 냉기의 통로(33)을 지나면서 하측으로 이동된 후 최하측의 저장공간(32d)과 냉기 흡입덕트(14)를 차례로 냉동실(F)로 다시 순환된다.First, a low temperature low pressure refrigerant flows through the evaporator 20 by driving a refrigeration cycle, and the air in the freezer compartment F is exchanged with a low temperature coolant while passing through a surface of the evaporator 20 to change into a low temperature cold. The cold air is pressurized by the blower fan 26 while maintaining the food stored in the freezing chamber F at a low temperature below zero and flows into the cold air discharge duct 12 of the partition 10. Then, the refrigerant through the cold air discharge duct 12 is moved downward by passing through the passage 33 of the cold air in the refrigerating chamber (R) by the refrigerant distributor 34, and then the storage space (32d) and cold air suction of the lowermost side The duct 14 is in turn circulated back to the freezer compartment F.
이때, 상기 냉기의 통로(33)를 지나는 냉기는 상기 저장공간(R1,R2,R3) 내의 냉기와 전도에 의한 열전달이 이루어져 선반(32a,32b,32c)의 위에 올려진 음식물의 저온 상태를 유지시킨다.At this time, the cold air passing through the passage 33 of the cold air is heat-transfer by the cold and conduction in the storage space (R1, R2, R3) is maintained to maintain a low temperature state of the food placed on the shelves (32a, 32b, 32c) Let's do it.
그러나, 종래의 냉장고는 증발기(20)를 통한 냉기가 최하측 저장공간(R4)을 제외한 나머지 저장공간(R1,R2,R3)으로는 열전도에 의해서만 열전달이 이루어져 냉장실(R) 내부의 온도편차가 생기고 냉각속도가 저하되는 문제점이 있다.However, in the conventional refrigerator, the heat is only transferred by the heat conduction to the remaining storage spaces R1, R2, and R3 except for the lowest storage space R4, except that the cold air through the evaporator 20 has a temperature deviation in the refrigerating chamber R. There is a problem that the cooling rate is generated.

The cold air is pressurized by the blower fan 76 while keeping the food stored in the freezing chamber F at a low temperature below zero and flows into the cold air discharge duct 62 of the partition 60. The cold air through the cold air discharge duct 62 is distributed into the refrigerating chamber R by the refrigerating chamber cold air distributor 84 and passes through the passage 83 of the cold air, thereby preventing the cold air from the shelves 82a, 82b, 82c, and 82d. The storage spaces (R1, R2, R3, R4) located in between are divided into a predetermined amount. The cold air dispersed into the storage spaces R1, R2, R3, and R4 keeps the temperature of the food or the container at a low temperature while directly contacting the food or the container placed on the shelves 82a, 82b, 82c, and 82d.
그리고, 상기 저장공간(R1,R2,R3,R4) 내측의 냉기는 상기 제 1 덕트(64a,64b,64c,64d)의 각각으로 유입되어 상기 제 2 덕트(64e)에서 모아진 후 상기 냉동실(F)로 재유입되어 상기 증발기(70)를 통하면서 상기의 과정을 반복하게 된다.The cold air inside the storage spaces R1, R2, R3, and R4 flows into each of the first ducts 64a, 64b, 64c, and 64d, collects in the second duct 64e, and is then stored in the freezing chamber F. Re-introduced into) and through the evaporator 70 to repeat the above process.
