摘要： Provided is an axial flow blower capable of improving an intake efficiency even when air is introduced from a plurality of suction openings. An axial flow blower includes a housing including an air blowing passage extending from a plurality of suction openings (lateral suction opening and lower suction opening) to an ejection opening, an electric motor, and an air blowing fan that blows air from the plurality of suction openings (lateral suction opening and lower suction opening) toward the ejection opening. An air blowing guide member is provided closer to the plurality of suction openings (lateral suction opening and lower suction opening) than to the air blowing fan, inside of the plurality of suction openings (lateral suction opening and lower suction opening). The air blowing guide member guides air introduced into the air blowing passage from the plurality of suction openings (lateral suction opening and lower suction opening) toward the air blowing fan.

摘要： Provided is an axial flow blower capable of effectively increasing a wind speed while suppressing decrease in a wind volume. The axial flow blower includes a housing including an air blowing passage extending from a suction opening to an ejection opening, an electric motor, and an air blowing fan that blows air from the suction opening toward the ejection opening. The housing is provided with a blow-out pipe that forms a portion of the air blowing passage extending in a direction along a rotation axis of the air blowing fan and has a distal end opening serving as the ejection opening, and a distal end portion of the blow-out pipe formed of a straight pipe is provided with an R part (first R part) formed of an outwardly rounded arc.
