And a portion of the remaining cold air is guided to the shroud 14 and free-falls, so that the refrigerating chamber 20 of the refrigerating chamber 20 is passed through the back duct 23b, the left side duct 24b, and the right side duct 25b. After being guided to the wall surface, cold air is discharged into the refrigerating chamber 20 through the rear duct 23b, the left side duct 24b, and the right side duct 25b.
토출된 냉기는 상기 냉장실(20)의 내부에 보관된 음식물을 적정 온도로 냉각한 후, 상기 냉장실(20)의 상측면에 형성된 상측면 흡입구(26a)와 배면 하단에 형성된 배면 흡입구(27a)를 통해 흡입되고, 흡입된 냉기는 상기 상측면 냉기흡입유로(26)와 배면 냉기흡입유로(27)를 통해 상기 냉각실(2)로 다시 유입되어 상기 증발기(3)에 의해 재 냉각된다.The discharged cold air cools the food stored in the refrigerating compartment 20 to an appropriate temperature, and then the upper suction port 26a formed on the upper side of the refrigerating compartment 20 and the rear suction port 27a formed on the lower bottom of the refrigerating compartment 20. The sucked cold air is introduced into the cooling chamber 2 again through the upper side cold air suction passage 26 and the rear cold air suction passage 27 and recooled by the evaporator 3.
재 냉각된 냉기는 상기 냉장고의 냉동실(10) 및 냉장실(20)에 재 유입되어 순환되며 연속적인 냉각을 실시하는 것이다.The re-cooled cold air is re-introduced into the freezer compartment 10 and the refrigerating compartment 20 of the refrigerator to circulate and perform continuous cooling.
이와 같이 본 발명에 의한 냉장고의 냉기 공급장치는 상기 냉장 시에 공급되는 냉기가 상기 배면 냉기안내유로, 좌측면 냉기안내유로, 우측면 냉기안내유로를 통해 골고루 공급되고, 공급된 냉기는 상기 냉장실의 상측면에 형성된 상측면 냉기흡입유로를 통해 흡입되어 재 냉각됨과 동시에 상기 냉장실의 배면 하단부에 형성된 배면 냉기흡입유로를 통해 흡입되어 재 냉각됨으로써, 상기 선반에 의해 구획된 냉장실칸에 골고루 냉기가 순환될 수 있는 것이다.As described above, in the cold air supply apparatus of the refrigerator according to the present invention, the cold air supplied at the time of refrigeration is evenly supplied through the rear cold air guide flow path, the left cold air guide flow path, and the right side cold air flow guide flow path, and the supplied cold air is supplied to the image of the refrigerating compartment. By being sucked and recooled through the upper side cold air suction passage formed on the side surface, the cold air is circulated evenly through the cold compartment compartment partitioned by the shelf by being re-cooled by being sucked through the rear cold air suction passage formed at the bottom lower end of the refrigerating compartment. It is.
이상에서 설명한 바와 같이 본 발명에 의한 냉장고의 냉기 공급장치는 냉장실의 좌측면, 우측면, 배면에 고르게 분포된 각각의 배면 냉기안내유로, 좌측면 냉기안내유로, 우측면 냉기안내유로를 통해 냉기가 토출되어 냉장실에 고르게 냉기를 공급되고, 상기 냉장실의 상측면 및 배면 하단부에 형성된 상측면 냉기흡입유로와 배면 냉기흡입유로를 통해 냉기를 흡입하는 순환구조로 이루어져 냉기가 원활히 순환됨으로써, 냉각효율이 상승하는 효과가 있다.As described above, the cold air supply device of the refrigerator according to the present invention is discharged through the cold air guide channel, the cold air guide channel on the left side, the cold air guide channel on the left side, and evenly distributed on the left, right and rear surfaces of the refrigerating compartment. Cold air is evenly supplied to the refrigerating chamber, and the cold air is smoothly circulated by an upper side cold air suction passage and a bottom cold air suction passage formed on the upper side and the bottom of the rear side of the refrigerating compartment so that the cooling efficiency is circulated smoothly, thereby increasing the cooling efficiency. There is.
