Definitions

  • An outdoor unit of air conditioner includes a fan blowing air by being rotated, a heat exchanger exchanging heat with air blown by the fan, a motor driving the fan, and a motor support member supporting the motor.
  • the cross-sectional shape of the motor support member may be formed on some portions adjacent to a blade of the fan.
  • the sealing member 47 is installed at an end portion in a direction perpendicular to FIG. 1 . Further, in order to stably install the sealing member 47 or reliably seal a portion to be sealed, it is appropriate that a sheet 421 is installed on the rectifying member 42. In addition, the sealing member 47 is installed to fill the gap between the motor supporter 41 and the rectifying member 42, but is not limited thereto. A cap formed of a resin may be installed instead of the sealing member 47.
  • the shape of the rear portion of the motor support member 40 is improved, it is possible to prevent interference between the rear end of the streamlined shape and the airflow in the blade rotation direction, which is a weak point of the streamlined shape.
