AIR BLOWING DEVICE

摘要

An air blowing device (5a; 5) used together with an electrostatic atomizing device (9) for generating electrically charged minute water particles is provided with: an air flow path (4a; 4); an air blowing fan (3) disposed within the air flow path; and a negative pressure section (8) provided so as to be recessed in a part of the wall which forms the air flow path, having an outer recess (6) on the outer surface side of the air flow path, and having an inner protrusion (7) on the inner surface side of the air flow path. The negative pressure section (8) has a smaller cross-sectional area than the remaining portion of the air flow path (4a; 4). The electrostatic atomizing device (9) is disposed outside the air flow path, and the discharge opening (10) of the electrostatic atomizing device communicates with the negative pressure section (8) of the air flow path, said discharge opening (10) discharging the electrically charged minute water particles.
