<P>PROBLEM TO BE SOLVED: To obtain a compact airflow variable blower for preventing cold draft and dew condensation. <P>SOLUTION: An airflow variable blower includes a body 1 which induces and mixes air in an air-conditioned space S with supplied air and blows out the mixed air into the air-conditioned space S, and airflow control means V for controlling a mixing ratio of the supplied air and the induced air and a blowout airflow of the mixed air. In the body 1, an interval part 2 is formed, and on the downwind side thereof, a plurality of air exhaust ports 4 exhausting the supplied air are disposed separately along the interval part 2 in its circumferential direction. On a downwind side of the air exhaust ports 4, an induction port 5 is disposed separately for each of the air exhaust ports 4 so as to induce air in the air-conditioned space S by blowing therein the supplied air exhausted from the air exhaust ports 4. Between the induction port 5 and the induction port 5, a guiding path 19 is provided for guiding the induced air around the overall circumference of the induction port 5. On a downwind side of the induction port 5, a mixed air blowout duct 6 is formed for guiding the mixed air of the supplied air and the induced air to the air-conditioned space S. An induction air duct 7 is formed for guiding the induced air from the air-conditioned space S to the induction port 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
