WIPO Patent Application WO/2019/208899
Kind Code:
A1
Abstract:
The present invention relates to a non-powered vent having a vortex formation region using internal and external air currents so as to prevent headwinds such that an indoor air current is smoothly discharged to the outside, and provides a non-powered vent comprising: a fixing member having a fixing flange part horizontally extended at a right angle at the lower end of a vertical cylinder of which the front and rear ends are open; a finishing cap part having a finishing cone part, which is formed as a circular inclined plane having a narrow upper side and a wide lower side so as to encompass a center portion passage thereof, an opening, which is formed at the narrow upper end of the finishing cone part, and a finishing flange part, which has a fastening hole and is formed at the lower end of the finishing cone part; a discharge cap part having a discharge cone part, which is formed as a circular inclined plane having a narrow upper side and a wide lower side so as to encompass a center portion passage thereof, and respectively having a bent edge portion formed at the upper end of the discharge cone part, a discharge flange part formed at the lower end of the discharge cone part, and a fastening hole formed in the discharge flange part, such that the fixing flange part and the discharge flange part are assembled and provided in correspondence; a headwinds preventing member, which has a semispherical curved plate body having a circularly protruding middle portion, has at least three supporting legs extending from the peripheral portion of the curved plate body and fastened in correspondence to the fastening holes of the stacked discharge cap parts, has an opening, through which the air current is guided, formed between the supporting legs, and has a circular groove and a first bent edge portion that are both formed along the circular peripheral portion of the curved plate body, thereby being provided between the stacked finishing cap part and discharge cap part; and a fastening member fastened and assembled by means of bolts and nuts penetrating the fastening holes of the discharge cap part, the headwinds preventing member, and the fixing members.
