发明名称 Blower and design method of discharge port thereof
摘要 A blower comprising: a centrifugal fan; a driving unit for rotating the centrifugal fan; a bracket including a base fixedly-coupled to one side of the driving unit and a protrusion protruded from the base in a shaft direction of the centrifugal fan; and a fan housing fixedly-coupled to the bracket so as to rotatably receive the centrifugal fan, and including a suction port formed at one side of the bracket in the shaft direction of the centrifugal fan so as to suck air by the rotation of the centrifugal fan, and a discharge port formed in a perpendicular direction of the suction port, for discharging the air sucked through the suction port, wherein one side of the discharge port is formed in 'V' shape by a first inclination surface formed in the protrusion of the bracket and a second inclination surface formed at the fan housing which is contact with one end of the protrusion, and at least one of the first and second inclination surfaces is formed in a curved line so as to increase a discharge area of the discharge port, whereby a flow rate discharged through the discharge port can uniformly be distributed so as to reduce noise and simultaneously increase a discharged air volume.
