    摘要: A humidification and air cleaning apparatus is provided, in which a wave having a predetermined cycle is formed on a plurality of blades of a blower fan, such that operating noise caused by a flow of discharged air may be minimized, and a wave is formed at a trailing edge, such that a phase difference may be formed for air to be separated, and air flow noise of the discharged air may be reduced.

    摘要: A humidification and air cleaning apparatus is provided that may include a water tank having a discharge port which is open toward an upper side, and a discharge grill disposed at the water tank and covering the discharge port. The discharge grill may have a plurality of vanes disposed at the discharge port and spaced apart from each other, and when viewed from a top, overlap each other to cover the discharge port. An edge of a vane may overlap an edge of an adjacent vane, thereby minimizing scattering of droplets to an indoor space while minimizing resistance of discharged air.

    摘要: A ceiling fan may include a column; a hub case coupled to the column and rotatable with respect to the column; and a plurality of blades disposed at the hub case, and arranged radially around the column. Each blade may include a lower blade having a first side coupled to the hub case and a second side, opposite to the first side, directed radially outwardly; an upper blade spaced apart from the lower blade, and having a first side coupled to the hub case and a second side, opposite to the first side, directed radially outwardly; and an air gap disposed between the lower blade and the upper blade. The blade may be formed as a tandem blade, thereby generating a greater lift force than a blade having one positive pressure surface and one negative pressure surface, such that an air volume may increase at a same power output.
