BLOWER AND OUTDOOR UNIT MOUNTING BLOWER

摘要

PROBLEM TO BE SOLVED: To improve aerodynamic performance of a blower having a stationary vane which is used for an outdoor unit of an air conditioner, an outdoor unit of a heat pump water heater and the like. ! SOLUTION: An orifice 9 provided on an outer peripheral side of a rotor vane 5 includes: a minimum diameter part 9x in which a gap between itself and an outer peripheral end of a rotary blade 4 becomes minimum; and a discharge side opening part 9y which is provided on a discharge side of the minimum diameter part 9x, and whose diameter is larger than the minimum diameter part 9x. A stationary blade 7 of a stationary vane 8 which is provided on the discharge side of the rotor vane 5 is provided so that an axial direction position of an outer peripheral end of a front edge is located between the minimum diameter part 9x and the discharge side opening part 9y. Thereby, a discharge air flow in a region from the outer peripheral side to the outer peripheral end of the rotor vane 5 flows between blades of
