Cyclonic dirt cup assembly
First Claim
1. A cyclonic dirt cup assembly for a vacuum cleaner, said cyclonic dirt cup assembly including:
- a container formed with an inlet opening for receiving a stream of dirt-laden air;
an inverted truncated cone positioned within the container and being formed with a wall, said wall having an outer surface; and
a baffle extending outwardly from the outer surface of the wall of the cone, said baffle being positioned adjacent to the inlet opening of the container and cooperating with said cone for directing the stream of dirt-laden air in a cyclonic manner about said outer surface of the wall of the wall of the cone.

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 filter for cleaning thereof.

15. A cyclonic dirt cup assembly for a vacuum cleaner, said cyclonic dirt cup assembly including:
-
a container formed with an inlet opening for receiving a stream of air; a frame member removably mounted within the container; a filter attached to the frame member, said filter being formed of an air permeable material for filtering the stream of air as said stream of air passes through said filter; and a cone positioned within the container and pivotally attached to the frame member, said cone being pivotable away from said frame member to provide access to the filter for cleaning thereof. - View Dependent Claims (16, 17, 18, 19, 20)
