Guide vane structure of fan-motor for vacuum cleaner

Vacuum cleaner fan according to the present invention the guide vane structure of the motor fan for cleaners - and the body portion on the plate body, which is installed inside an impeller casing of the motor, are provided at predetermined intervals on the upper surface of the edge the body portion of the air passing through the impeller and a plurality of diffuser for increasing a pressure, passes through the body is formed on the bottom is formed on the outer surface of the plurality of rear vanes and the diffuser for guiding the pressure rises the air by the diffuser toward the motor portion diffuser comprises the air to the airfoil to guide toward the rear vane, by the air passing through the diffuser to be guided toward the rear vane by the airfoil, the air passing through the diffuser does not stay in the space portion between the guide vane and the impeller casing as it is to be guided towards the rear vanes, and reduced flow losses, and therefore - the cooling efficiency of the suction motor and the motor is increases.
