Abstract
An office machine including a machine frame defining an operating environment, operating components mounted within the frame and requiring environmental conditioning such as cooling and cleaning, and an air blower for conditioning the operating environment within the frame. The air blower includes a housing having a housing wall defining an air path and an air discharge opening, a discharge nozzle, mounted over the discharge opening for directing air being discharged away from the housing, a pinch point formed between the housing wall and the discharge nozzle at the discharge opening, an air moving assembly including a rotatable impeller mounted within the housing for drawing air into the air path, and a blower noise reducing device on the pinch point for minimizing air stagnation at the pinch point. The blower noise reducing device includes a first surface for protruding into the air path, and a second surface for protruding into the discharge nozzle, for minimizing air stagnation within the air path and within the discharge nozzle, thereby reducing bower noise.
