A blower device includes a panel, a frame member disposed to surround the panel, a plurality of fans configured to blow out air through a plurality of blow out ports of the frame member, a control unit configured to control the rotational speed of the fans, and a camera configured to detect presence of a person in front of the panel. The control unit is configured to adjust the flow rate and the flow speed of air blown out through the blow out ports to thereby change the direction of an air flow generated by mutual collision of the blown-out air so that the air is blown out toward the person detected by the camera.
