AIR BLOWER, AIRFLOW PROVISION METHOD AND AIRFLOW PROVISION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an air blower capable of eliminating uneasiness due to contact caused by internally encapsulating an impeller, providing airflow over a wide range and at substantially even wind speed, and easily changing a ventilation direction of the airflow.;SOLUTION: An air blower 11 comprises a changeover unit 24 configured to change over a ventilation direction of air discharged from a discharge port 19 to a vertical direction with respect to a horizontal face. The changeover unit 24 is provided in a nozzle 13, and even when the ventilation direction is changed by the changeover unit 24, never changes a clearance between a plurality of nozzles 13, such as blocking a part of the clearance therebetween, so that a ventilation direction of face airflow fed from the air blower 11 can be changed without disturbing induced air flow 26 induced in an induction wind channel 22.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2019,JPO&INPIT
