摘要： A bi-directional blower includes a blower body for guiding for air to flow along an entire circumference scroll shape of an inner space of the blower body. The blower body divides the inner space into an upward space and a downward space to guide air flow. The blower body comprises: an upper discharge case discharging the air flow along the entire circumference scroll shape toward the upward space through an upper discharge port; and a lower discharge case discharging the air flow along the entire circumference scroll shape toward the downward space through a lower discharge port.

摘要： A bidirectional blower may include a blower body having a scroll rib making a length of an entire perimeter scroll guiding air flow in an internal space to an outlet end portion where air discharge is performed, and a fan in which a blade having an inlet angle of an acute angle and an outlet angle of an obtuse angle draws external air into the internal air, thereby realizing the characteristics of lowering an operating noise by preventing a generation of vortex while enhancing air volume performance suitable for a ventilation seat.
