PROBLEM TO BE SOLVED: To provide an air blower enhancing compactness while providing extended blowout air.SOLUTION: An air blower includes a suction port for taking air into a cylindrical casing, high pressure generating means constituted by an impeller for generating high pressure air and a motor for driving the impeller, a blowout port for blowing out the high pressure air, a first air channel for guiding the air taken from the suction port to the blowout port through the high pressure air generating means, a plurality of induction air suction ports of the same shape induced by the air blown out of the blowout port to suck the air and provided at equal intervals in a circumferential direction of the casing, an induction air mixing section for mixing the air sucked by the plurality of the induction air suction ports, an induction air blowout port for blowing out the air mixed in the induction air mixing section, a second air channel communicating with the induction air blowout port from the induction air suction port through the induction air mixing section, and adjustment means for changing an opening area of the induction air suction port.SELECTED DRAWING: Figure 7 |
