Kind Code:
A1
Abstract:
A blower (1) is provided with: a fluid introducing box (10); a fan (30) for blowing out at least one of a first fluid and a second fluid which are introduced into the fluid introducing box; and a casing (50) housing the fan. The blower is provided with a tubular body (72) for guiding the first fluid and the second fluid to the fan in an inside/outside separated state, and a tube upper-end portion (71) forming an air entry for causing air to flow into the tubular body. The casing has, on one side in the axial direction, an inlet forming portion (60) forming an inlet (61) of air toward the fan. The tube upper-end portion is disposed between the inlet forming portion and the fluid introducing box in a position overlapping a part of each of the inlet and the inlet forming portion in the axial direction. The interval between the tube upper-end portion and the inlet forming portion in the axial direction, compared to a flow channel entry (81) of a gap flow channel (80) formed between the tube upper-end portion and the inlet forming portion, is reduced on a back side away from the flow channel entry of the gap flow channel.
