Vent structure and building ventilation system and humidifier that adopt the vent structure

摘要

PROBLEM TO BE SOLVED: To provide a vent structure capable of exerting an antibacterial action, a building ventilation system adopting the vent structure, and a humidifier. SOLUTION: The vent structure has an antibacterial action, and a tubular shape is formed by joining copper plates having a predetermined length, width and thickness in the longitudinal direction, or one end in the longitudinal direction. A spiral copper ring member that moves away from the center as it turns from the side to the other end is formed, and the copper ring member is attached to the vent. By adopting such a configuration, when air passes through the vent, it comes into contact with the copper ring member, and air is supplied from the vent while carrying copper ions, and the air is used at the air destination. It has an antibacterial effect. [Selection diagram] Fig. 1
