Abstract
A cyclone assembly for a surface cleaning apparatus has a first cyclonic cleaning stage and a second cyclonic cleaning stage downstream from the first cyclonic cleaning stage. The first cyclonic cleaning stage has a first cyclonic stage air outlet and the second cyclonic cleaning stage has a plurality of second cyclonic stage cyclone air inlets and a second cyclonic stage air inlet end. The first cyclonic cleaning stage air outlet communicates directly with an annular flow region that extends around the second stage air inlet end of the second cyclonic stage.
Claims19
A surface cleaning apparatus having a cyclone assembly, the cyclone assembly comprising:
- (a) a first cyclonic cleaning stage comprising a first stage cyclone having a first stage cyclone chamber, a first stage cyclone axis, a first cyclonic stage air inlet, a first cyclonic stage air outlet and a first cyclonic stage air outlet end;
- (b) a second cyclonic cleaning stage downstream from the first cyclonic cleaning stage and comprising a second stage cyclone chamber, wherein the second stage cyclone chamber has a second stage cyclone axis, a plurality of second cyclonic stage cyclone air inlets extending around and radially outward of the second stage cyclone axis, and a second cyclonic stage air inlet end;
- and,
- (c) an annular flow space positioned radially outwardly of the plurality of second stage cyclone air inlets and extending around a portion of the second stage cyclonic chamber having the plurality of second stage cyclone air inlets,
- wherein the plurality of second stage cyclonic air inlets direct air into the second stage cyclone chamber from the annular flow space.
