Title:
BLOWER COMPRISING CYLINDRICAL ROTARY PROPELLER
Document Type and Number:
WIPO Patent Application WO/2023/153620
Kind Code:
A1
Abstract:
Disclosed is a blower comprising a cylindrical rotary propeller, which creates high pressure by centrifugal force and imparts linearity to the air being discharged therefrom by using the venturi effect, so that a large amount of air flows there-through in a shorter period of time compared to a conventional ventilator and accordingly a large amount of harmful substances can be discharged rapidly in the event of a fire. A blower comprising a cylindrical rotary propeller comprises: a cylinder-shaped propeller which has a flow path formed therein and rotates in the circumferential direction such that the air flowing through the flow path is guided in the axial direction; and a rotary blade which is accommodated inside the propeller and is rotated by the propeller such that air is drawn from the outside into the flow path, flows there-through, and is discharged from the front side of the propeller, wherein the rotary blade is coupled to the inner circumferential surface of the propeller and has a spiral structure that rotates along with the propeller so as to guide the air flowing through the flow path in the spiral direction, and the center portion of the rotary blade is hollow in the axial direction of the propeller.
