Abstract
A cyclonic dirt cup assembly for a vacuum cleaner has a generally conical truncated cone positioned within a dirt cup of the vacuum cleaner. The dirt cup has a wall formed with an air inlet opening for receiving a stream of dirt-laden air within the dirt cup. The cone is pivotally connected to a frame member which is removably mounted within the dirt cup. A baffle extends outwardly from a wall of the cone and is positioned adjacent the air inlet opening of the dirt cup for directing the stream of dirt-laden air in a cyclonic manner. The baffle includes a top wall, a side wall and a bottom wall. The baffle walls, the wall of the dirt cup and a wall of the cone form an air directing compartment which receives the dirt-laden air input through the inlet opening. The air directing compartment is formed with a side exit opening which provides a tangential opening for the dirt-laden air to exit the air directing compartment and begins a cyclonic action within the container for filtering dirt particles from the airstream. A filter is positioned on the frame member opposite the cone for further filtering the airstream. The cone pivots away from the frame member to provide access to the filt…
