摘要： A blower of the present disclosure includes: a lower case having a suction port; an upper case which has a pair of towers that are spaced apart from each other and form a space through which a discharge air flows therebetween; and a blower fan which is disposed inside the lower case and discharges air to the upper case, wherein each of the pair of towers has a discharge port that is elongated in an up-down direction and disposed closer to a rear end of the tower than a front end, and has an air guide, which is disposed therein, that guides the air discharged by the blower fan to the discharge port, wherein the air guide is convex upward, has one end disposed near a middle between the front end and the rear end of the tower, and has the other end disposed near a middle of a vertical height of the discharge port, wherein the other end is disposed higher than the one end, so that the direction of air flow discharged from the fan can be smoothly switched to the discharge port side by only a single air guide, thereby minimizing the flow resistance inside the blower and greatly improving the economic efficiency and manufacturability of the blower.

摘要： First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.
