상기 응축된 고온, 고압의 액체냉매는 팽창밸브를 거치면서 저온, 저압의 액체냉매로 변환되고, 상기 저온, 저압의 액체냉매는 상기 증발기(3)를 지나면서 저온, 저압의 기체냉매로 변환되면서 증발되고, 상기 증발기(3)의 증발작용에 의해 주위의 공기가 열 교환되어 주변의 공기를 냉각시키므로 냉기가 발생되는 것이다.The condensed high temperature and high pressure liquid refrigerant is converted into a low temperature and low pressure liquid refrigerant through an expansion valve, and the low temperature and low pressure liquid refrigerant is converted into a low temperature and low pressure gas refrigerant while passing through the evaporator (3). By evaporation, the surrounding air is heat exchanged by the evaporation of the evaporator 3 to cool the surrounding air, thereby generating cold air.
이와 같이 발생된 냉기의 일부는 상기 본체(1)의 배면 상부에 설치된 송풍팬(13)의 회전에 의해 강제 송풍되고, 상기 냉동실 토출구(12a)를 통해 상기냉동실(10) 내부로 공급되어 저장된 음식물을 일정 온도까지 냉각시키고, 나머지 냉기의 일부는 상기 냉기안내유로(23)의 내부에 장착된 보조 송풍팬(25)의 강제 송풍에 의해 상기 토출측 배면덕트(23d)를 통해 유입되고 상기 토출측 수직덕트(23c)로 안내된다.Part of the cold air generated as described above is forcedly blown by the rotation of the blower fan 13 installed on the rear surface of the main body 1, and is supplied to and stored in the freezer compartment 10 through the freezer compartment outlet 12a. Cool air to a predetermined temperature, and a part of the remaining cold air is introduced through the discharge side rear duct 23d by forced air blowing of the auxiliary blower fan 25 mounted inside the cold air guide passage 23 and the discharge side vertical duct. Guided to 23c.
상기 토출측 수직덕트(23c)로 안내된 냉기는 상기 토출측 수평덕트(23b)의 일측면에 형성된 상기 토출구(23a)를 통해 냉장실(20)의 상측 전면에 걸쳐 고르게 상기 냉장실(20) 내부에 공급된다.The cool air guided to the discharge side vertical duct 23c is uniformly supplied to the inside of the refrigerating chamber 20 through the discharge port 23a formed on one side of the discharge side horizontal duct 23b. .
상기 토출구(23a)를 통해 토출된 냉기가 자유낙하 되어, 상기 선반(22)에 형성된 홀(22a)을 통하여 상기 선반(22)에 의해 구획된 냉장실(20) 내부의 각각의 칸에 공급된 후, 그 냉기는 상기 냉장실(20)의 배면에 형성된 각각의 흡입구(24a)를 통해 상기 흡입측 수평덕트(24a)에 흡입된다.After the cool air discharged through the discharge port 23a falls freely and is supplied to respective compartments in the refrigerating chamber 20 partitioned by the shelf 22 through the holes 22a formed in the shelf 22. The cold air is sucked into the suction side horizontal duct 24a through each suction port 24a formed on the rear surface of the refrigerating chamber 20.
각각의 칸에서 흡입된 냉기는 상기 흡입측 수직덕트(24c)로 안내되고, 상기 흡입측 수직덕트(24c)를 통해 상기 냉각기실(2)로 안내되어 상기 증발기(3)에 의해 재 냉각되며, 재 냉각된 냉기는 냉동실(10) 및 냉장실(20) 재 유입되는 순환을 반복적으로 실시하게 되는 것이다.The cold air sucked in each compartment is guided to the suction side vertical duct 24c, and is led to the cooler chamber 2 through the suction side vertical duct 24c and recooled by the evaporator 3, The re-cooled cold air is repeatedly performed to re-introduce the freezing compartment 10 and the refrigerating compartment 20.
이와 같이 본 발명에 의한 냉장고의 냉기 공급장치는 상기 냉장실에 공급되는 냉기안내유로를 상기 냉동실에 공급되는 유로와 별도로 구성시키고, 상기 냉기안내유로 내부에 장착된 보조 송풍팬을 구동시켜 상기 냉장실에 냉기를 공급한다.As described above, the cold air supply apparatus of the refrigerator according to the present invention configures the cold air guide flow path supplied to the refrigerating compartment separately from the flow path supplied to the freezing compartment, and drives the auxiliary blower fan mounted inside the cold air flow guide passage to cool the air in the refrigerating compartment. To supply.
또한, 상기 냉장실의 상측면에 형성된 토출구를 통해 토출된 냉기는 자유낙하되고, 상기 선반에 형성된 홀을 통하여 상기 냉장실 내부에 고르게 공급됨으로써, 냉장고의 냉각효율을 높일 수 있다.In addition, the cold air discharged through the discharge port formed on the upper side of the refrigerating compartment is freely dropped, and evenly supplied into the refrigerating compartment through the hole formed in the shelf, it is possible to increase the cooling efficiency of the refrigerator.
이상에서 설명한 바와 같이 본 발명에 의한 냉장고의 냉기 공급장치는 상기 냉장실에 냉기를 공급하기 위한 냉기안내유로가 상기 냉동실에 냉기를 공급하기 위한 유로와 별도로 형성되고, 상기 냉기안내유로의 일정부위에 장착된 보조 송풍팬을 구동시켜 냉기를 공급함으로써, 원활한 냉기의 공급을 이룬다.As described above, the cold air supply apparatus of the refrigerator according to the present invention has a cold air guide passage for supplying cold air to the refrigerating compartment and is formed separately from a flow path for supplying cold air to the freezer compartment, and is mounted at a predetermined portion of the cold air guide passage. By supplying cold air by driving the supplementary blower fan, a smooth supply of cold air is achieved.
또한, 선반의 일정부위에 형성된 홀을 통해 냉기가 유동되고, 상기 선반에 의해 구획된 상기 냉장실의 각각의 칸에 냉기흡입유로가 형성되어 냉기의 순환이 원활히 이루어짐으로써, 고내의 온도를 고르게 분포시키고, 냉각효율을 높일 수 있는 효과가 있다.In addition, cold air flows through a hole formed in a predetermined portion of the shelf, and a cold air suction flow path is formed in each compartment of the refrigerating compartment partitioned by the shelf to smoothly circulate the cold air, thereby uniformly distributing the temperature in the refrigerator.
