SOUNDPROOF VENTILATION DOOR

摘要

A multi-functional soundproof ventilation door is provided to prevent invasion of privacy, and to shut off noise by sufficiently ventilating air with a long distance guide vane and a soundproof material without entirely opening an entrance. A multi-functional soundproof ventilation door(10) includes an intake port formed at the upper or lower part of the front of the door, a discharge port formed at the upper or lower part of a rear part of the door and arranged diagonally to the intake port, an opening system(13) opening and closing the intake port and the discharge port, and a guide vane(14) alternately formed in the door. The opening system has a first opening unit(131) placed in the intake port, a second opening unit(132) placed in the discharge port, and a driving unit(133) connecting and sliding the first opening unit and the second opening unit. Opening parts(134) are formed in upper parts of the first and second opening units and made of mesh, and closing parts(135) are formed in lower parts of the first and second opening units. Inflow of external air is shut off by integrating the closing part with the intake port and the discharge port in moving down the first opening unit and the second opening unit with the driving unit.
