In detail, the impeller 61 is rotated by the flow force of the cold air blown by the blowing fan 40 to the discharge opening 59 through the upper duct 57. However, the cold air dispersion member 60 according to the present invention may further include a driving unit (not shown) for transmitting a driving force to the impeller 61. Here, the driving unit may be provided as a motor. This drive unit is preferably driven in conjunction with the drive of the blower fan (40).

이하, 이러한 구성을 갖는 냉장고(1)의 작동방법을 첨부도면을 참조하여 살펴본다.Hereinafter, an operation method of the refrigerator 1 having such a configuration will be described with reference to the accompanying drawings.

우선, 저장실(15)의 온도가 상승하여 저장실(15)의 냉각조건이 만족되면 압 축기(미도시)와 송풍팬(40)을 구동시킨다. 송풍팬(40)이 구동하면 저장실(15) 내부의 공기가 공기유입구(54)를 통하여 증발기(30)측으로 유입된다. 증발기(30)는 유입된 공기와 열교환하여 냉기를 생성한다. 증발기(30)에서 생성된 냉기는 송풍팬(40)에 의하여 공기토출구(56)를 통하여 저장실(15)의 후방영역으로 골고루 토출된다.First, when the temperature of the storage chamber 15 rises and the cooling condition of the storage chamber 15 is satisfied, the compressor (not shown) and the blower fan 40 are driven.

The cold guide 63 is rotated by the rotation of the impeller 61. As the cold guide 63 rotates, air introduced into the upper duct 57 is distributed and discharged downward from the upper portion of the storage chamber 15 through the cold air discharge port 65. Thus, the cold air can be evenly distributed not only in the rear region of the storage chamber 15 but also in the upper region of the storage chamber 15, thereby minimizing the temperature difference between the upper and lower regions of the storage chamber 15.
