Abstract: 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.

Abstract: The present disclosure relates to a centrifugal fan and a method for manufacturing the same. The centrifugal fan can easily implement a three-dimensional blade by including a main plate, a blade, and a shroud that injection-molded as one body, thereby reducing the weight of the centrifugal fan and improving the operating efficiency. In addition, since assembly processes such as fastening or welding are unnecessary when manufacturing the blade, the defect rate of the blade can be reduced and the fluidity performance can be prevented from deteriorating due to traces of welded areas.

Abstract: 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.
