  • Publication number: 20240131922
    Abstract: A variable grille apparatus can adjust a flow rate of air flowing through a grille and upgrade an opening/closing operation when adjusting the flow rate of the air, thereby improving merchantability. In addition, by diversifying the opening/closing operation of the grille such as sequentially operating or simultaneously operating the opening/closing operation of the grille, it is possible to upgrade the opening/closing operation of the grille, diversify the exterior design, and secure the flow rate of air through the optimization of the structural arrangement.
