<P>PROBLEM TO BE SOLVED: To provide a fan that can widen a cool air region by a configuration for changing a wind direction with the fan being fixed, can suppress draft feeling when a circulation effect is obtained, and can obtain a comfortable air flow effect. <P>SOLUTION: The fan includes: an inlet opening 3 for taking air into a box 2; a high-pressure air generation section 6 to which an impeller 4 for generating high-pressure air and a high-pressure air generating means configured by a motor 5 for driving the impeller 4 are provided; and dual annular inner and outer air flow outlet sections 8, 9 having an outlet opening 7 for discharging the high-pressure air as an air flow. Air blowing angles in the inner and outer directions with respect to the annular shape are configured to be changed by changing an air amount of each air flow outlet section with an air flow changing mechanism in the high-pressure air generation section 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
