Dirt separation and collection assembly for vacuum cleaner
First Claim
1. An assembly for separating and collecting dirt from an air stream, comprising:
- an elongated container having a substantially cylindrical sidewall, a bottom and a top;
an inlet formed in the sidewall;
a disrupter ring mounted on the inner surface of the sidewall to define a first stage separation zone between the top and the disrupter ring;
a second separation zone including a frusto-conical cyclone disposed coaxially within the first stage separation zone; and
a shroud with a plurality of holes disposed over the second separation zone to direct air to the second stage separation zone.

Abstract
A dirt separation and collection assembly suitable for use in a bagless vacuum cleaner including two dirt separation and collection zones is provided. Dirty air enters the upper portion of a container and enters a first stage dirt separation zone including a disruptor ring extending inwardly from the outer wall to allow coarse dirt particles and fibers to pass through and collect at the base of the outer wall of the device. The spinning air is then drawn through a conical shroud and fed into a second stage conical separator for separating fine dirt particles and collecting them in an inner substantially cylindrical collection chamber. Air exits the conical separator at the opposite cone opening before being drawn to the suction source. Elements may be oriented upwardly or downwardly depending upon the configuration of the housing for receiving the dirt separation and collection assembly.

11. A vacuum cleaner housing including a suction source and a dirty air inlet and having a cavity for receiving a dirt separation and collection container, the container comprising:
-
an outer elongated container having a substantially cylindrical sidewall, a bottom and a top;
an inlet formed in the sidewall;
a disrupter ring mounted on the inner surface of the sidewall to define a first stage separation zone;
a second separation zone including a frusto-conical cyclone having an inlet opening larger than the opposed opening of the cone;
the second stage separation zone disposed coaxially within the first stage separation zone;
a shroud with a plurality of holes disposed over the second separation zone to direct air to the larger cone opening of the second stage separation zone.
