Abstract:
1. A motor-noise absorbing apparatus for absorbing noise generated in a motor housing when air taken in through a top of a motor cover from a guide vein integrally formed with the motor cover below a bottom surface of an impeller via an impeller vein of the impeller, and then discharged to a plurality of windows of the motor housing between the motor housing and a stator core and between the stator core and a rotor, the apparatus comprising: a body seated and fixed on a peripheral part of an opening of the motor housing to restrict an amount of air discharged between the motor housing and the stator core; a first air discharging part formed in the middle of the body, so that most of the air is discharged between the stator core and the rotor; and at least one second air discharging part formed to penetrate a peripheral part of the body, so that a portion of the air is discharged between the motor housing and the stator core.
