Abstract

PURPOSE: To decrease noises and also to improve productivity by forming a noise suppressing material having a taper hole which is adjusted to the direction in which the air flows on suction side and discharge side of a blower being simply made through punching.
CONSTITUTION: A blower comprises an impeller 103 having a blade 103-1 running by a driving motor 101, a casing 102, an air passage 104, an air passage divider 105, a suction port 107, a discharge port 108, etc. Suction/discharge side noise supressing materials 111, 112 adjusted to the direction in which sucked/discharged airs 109, 110 flow and noise suppressing materials 111-1, 112-1 with taper holes which are through to suction/discharge holes 111-d, 112-d and manufactured through punching so as to have bubbles on the air passage are provided on the suction port 107 and the discharge port 108 sides, respectively. Thus, a vortex flow blower for which loss and noise will less arise from a sudden change in the air flow direction can be manufactured with excellent productivity.
