Abstract
A cyclonic separator for a vacuum cleaner that includes a cyclone stage, a chamber and a silencer. The chamber has a plurality of ports through which fluid from the cyclone stage enters the chamber. The silencer is located in the chamber and includes a plurality of baffles. Fluid entering the chamber through the ports collides with the baffles, which act to reduce noise.
Claims22
A cyclonic separator for a vacuum cleaner comprising:
- a cyclone stage;
- a chamber comprising a plurality of ports through which fluid from the cyclone stage enters the chamber;
- and
- a silencer comprising a plurality of baffles, wherein each of the baffles is generally planar, and the silencer is located in the chamber such that fluid entering the chamber through one of the ports collides with a first side of one of the baffles and fluid entering the chamber through another of the ports collides with a second opposite side of the one of the baffles.
