And, one side is in communication with the freezer compartment 11 to introduce the cold air circulating fan 120 for blowing the cold air heat exchanged in the evaporator 80, and the cold air blown by the cold air circulation fan 120 into the refrigerating chamber (12). Cold air circulation duct 30 formed on the other side inside the refrigerating chamber 12, shelves 50a, 50b, 50c installed in parallel in order to load the cooled object brought into the refrigerating chamber 12, and a cold air circulation fan ( The damper 100 installed in the middle of the cold air circulation duct 30 and the cold air circulation duct 30 introduced into the refrigerator compartment circulation duct 30 by opening the damper 100 to inflow or block the cold air blown by the 120. Cold air discharge ports 31a, 31b, 31c formed in the cold air circulation duct 30 are provided to separately discharge cold air to the shelves 50a, 50b, 50c. In addition, in the conventional refrigerator, temperature sensing sensors 110a and 110b are installed in place of the freezing chamber 11 and the refrigerating chamber 12 to detect the internal temperatures of the freezing chamber 11 and the refrigerating chamber 12, respectively. 12, the vegetable box 150 is provided in the lower portion, the compressor 60 is installed at the rear of the vegetable box 150, the control unit 140 for controlling each part in the door for opening and closing the freezer compartment 11 is built-in.

종래의 냉장고는 냉동실(11)과 냉장실(12)를 냉각시키기 위해 냉기순환팬(120)을 구동하여 증발기(80)에서 열교환된 냉기를 냉동실(11)과 냉장실(12)로 송풍하고, 이 송풍된 냉기는 내동실(11)과 냉장실(12)로 유입된 후 냉동실(11)과 냉장실(12)의 상단과 하단에 마련된 냉기유입구(31)(32)를 통해 증발기(80)로 다시 순환하는 과정을 반복하게 되는데, 이때, 제어부(140)는 냉동실 온도감지센서(110a)를 통해 감지한 냉동실의 고내온도와 설정온도를 비교하여 압축기(60)를 온,오프구동하고 냉가순환팬(120)을 구동하여 냉동실(11)을 냉각시키고 냉장실 온도감지센서(110b)를 통해 감지한 냉장실의 고내온도와 설정온도를 비교하여 댐퍼(100)를 개폐시켜 냉장실(12)을 냉각시키게 된다.The conventional refrigerator drives the cold air circulation fan 120 to cool the freezing compartment 11 and the refrigerating compartment 12, and blows cold air heat-exchanged in the evaporator 80 to the freezing compartment 11 and the refrigerating compartment 12, and blows this air. The cold air is introduced into the inner cavity 11 and the refrigerating chamber 12 and then circulated back to the evaporator 80 through the cold air inlets 31 and 32 provided at the upper and lower ends of the freezing chamber 11 and the refrigerating chamber 12.
