    Abstract: A cross flow fan and an air conditioner having the same are provided. The cross flow fan may include a fixing member having a plate shape, and a plurality of blades fixed to one surface of the fixing member. The plurality of blades may be arranged spaced apart from each other in a circumferential direction. An inner edge may define an end of a side of each of the plurality of blades, the inner edge extending toward a rotational shaft of the plurality of blades, and an outer edge may define an end opposite to the inner edge. A protrusion may protrude from the outer edge in one direction.

    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.

    IPC: F04D29/40

    CPC classification number: F04D29/403

    Abstract: A blower is provided that may include a fan that creates airflow; a lower body forming a lower space therein in which the fan may be disposed, and having at least one suction hole through which air passes; a first upper body positioned above the lower body, and forming a first inner space that communicates with the lower space of the lower body; a second upper body positioned above the lower body, and forming a second inner space that communicates with the lower space of the lower body, the second upper body being spaced apart from the first upper body; and a space formed between the first upper body and the second upper body, and opened in a frontward-rearward direction. The first upper body may include a first slit formed through the first upper body such that air in the first inner space may be discharged into the space, and the second upper body may include a second slit formed through the second upper body such that air in the second inner space may be discharged into the space.
