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.
