No Power Fixed type Ventilator for Improving Ventilation Performance

摘要

The present invention relates to a non-powered fixed ventureta with improved intake and discharge performance, and is installed in the fixed die (B1) installed in the ventilation port (V1), and the through holes (111a, 112a) are formed. Airflow guide members 111 and 112 for guiding the air discharged from (V1) to be exhausted upward, a cover 120 provided above the airflow guide member 112, and airflow guide members 111 and 112 and cover 120 In the non-powered fixed ventureta comprising spacers 131 and 132 provided between, one side is rotatably provided on the cover 120 and the other side is rotated on the fixed die (B1) inside the airflow guide members 111 and 112 A vertical rotating rod 140 provided so as to be possible, a rotating body fixed to the vertical rotating rod 140 and rotating by the wind blowing from the outside to rotate the vertical rotating rod 140, and a rotating body fixed to the vertical rotating rod 140 and vertically As the rotating rod 140 rotates, a discharge impeller 181 for discharging the contaminated air in the ventilator V1 upward by rotating is further included, and according to this, there is an advantage in that the suction and discharge performance is improved by non-powered power.
