Blower comprising a fan installed in an inner space of a lower body having a first and second upper body positioned above and a space formed between the bodies wherein the bodies have a first and second openings formed through respective boundary surfaces which are opened and closed by a door assembly

A blower, comprising:

• a fan that creates airflow;
• a lower body forming an inner space in which the fan is installed, and having at least one suction hole through which air passes;
• an upper body positioned above the lower body and including a first upper body forming a first inner space that communicates with the inner space of the lower body, and a second upper body forming a second inner space that communicates with the inner space of the lower body and spaced apart from the first upper body;
• a space formed between the first upper body and the second upper body and opened in a frontward-rearward direction;
• a first opening formed through a first boundary surface of the first upper body facing the space;
• a second opening formed through a second boundary surface of the second upper body facing the space;
• a door assembly including a first door installed at the first upper body and that opens and closes the first opening, and a second door installed at the second upper body and that opens and closes the second opening, wherein the first door comprises a plurality of first doors sequentially disposed at the first opening in a widthwise direction of the first opening, and wherein the second door comprises a plurality of second doors sequentially disposed at the second opening in a widthwise direction of the second opening;
• and
• a controller configured to control opening and closing of the plurality of first doors and the plurality of second doors.
