By the repulsive force, the duct member 12 is rotated by the arrow G which is opposite to the cold air rotation, thereby making the circulation of the cold air more smooth.
이상의 설명에서와 같이 본 고안은 고내의 길이방향 중앙에 덕트부재가 설치되어 외부로 부터의 열손실을 감소시킬 수 있으며, 일정구간마다 형성된 냉기토출구 측면에 돌출형성된 안내부에 의해 덕트부재가 회전됨으로 냉각효율을 한층 높일수 있는 효과가 있다.As described in the above description, the present invention can reduce heat loss from the outside by installing a duct member in the longitudinal center of the furnace, and the duct member is rotated by a guide formed on the side of the cold air outlet formed at a predetermined interval. There is an effect that can further increase the cooling efficiency.
