As shown in FIG. (11) and the refrigerating compartment 12 for refrigerating, the freezer compartment 13 installed at the front of the main body 10 to open and close the freezer compartment 11, and the refrigerating compartment door 14 for opening and closing the refrigerating compartment 12; It is largely composed of a freezing cycle for making cold air required for cooling the freezing chamber 11 and the refrigerating chamber 12, and a cold air supply device for sending the cold air made in the freezing cycle to the freezing chamber 11 and the refrigerating chamber 12.
상기 냉기공급장치는 도 2에 나타낸 바와 같이, 냉장고의 사절부(20)에 의해 냉동실(11)과 냉장실(12)로 분리구획되고, 냉동실(11)의 내측에는 냉동실루버(22)와 루버절연물(24)이 형성되어 냉동실(11)과 냉각기실(26)을 격벽시켜 냉동실(11)의 공간을 형성한다.As shown in FIG. 2, the cold air supply device is divided into a freezing compartment 11 and a refrigerating compartment 12 by a trimming section 20 of a refrigerator, and inside the freezing compartment 11, a freezing chamber 22 and a louver insulator. A 24 is formed to partition the freezing chamber 11 and the cooler chamber 26 to form a space of the freezing chamber 11.
상기 냉동실루버(22)의 상측에는 냉기토출구(28)가 형성된다.The cold air outlet 28 is formed on the freezing chamber 22.
상기 냉각기실(26)의 내측에는 냉각기(30)가 설치되고, 상기 냉각기(30)의 상측에는 냉동실팬(32) 및 냉장실팬(미도시)이 설치된다.The cooler 30 is installed inside the cooler chamber 26, and a freezer compartment fan 32 and a refrigerating chamber fan (not shown) are installed above the cooler 30.
이러한 구성으로 이루어진 종래의 냉동실 냉기공급장치는 냉각기실(30)에서 냉동싸이클에 의해 생성된 냉기가 냉동실팬(32)의 급속회전에 의해 상기 루버절연물(24)에 형성된 냉기토출구를 통해 냉동실(11)의 후방에서 전방으로 냉기가 토출된다.In the conventional freezer compartment cold air supply device having such a configuration, the cold air generated by the freezing cycle in the freezer compartment 30 has the freezer compartment 11 through the cold air outlet formed in the louver insulator 24 by the rapid rotation of the freezer compartment fan 32.
