Abstract
A cyclonic separating apparatus includes a separating chamber, an inlet communicating with the separating chamber and an outlet formed by a conduit communicating with an interior portion of the separating chamber and having a longitudinal axis, wherein a single planar baffle projects radially inwardly from an interior surface of the conduit towards the longitudinal axis. The presence of the baffle in the outlet has the effect of reducing noise generated by the apparatus when in use and also improves pressure recovery.
Claims25
A cyclonic separating apparatus, comprising a separating chamber, an inlet communicating with the separating chamber and an outlet, the outlet being formed by a conduit communicating with an interior portion of the separating chamber and having a longitudinal axis, wherein a single planar baffle projects radially inwardly from an interior surface of the conduit towards the longitudinal axis to a depth of at most about one third of a diameter of the conduit.
A vacuum cleaner comprising:
- a first cyclonic separation chamber located along an airflow pathway;
- and
- a plurality of second cyclonic separation chambers arranged downstream from the first cyclonic separation chamber along the airflow pathway, the second cyclonic separation chambers being arranged in parallel with respect to the airflow pathway;
- wherein at least one of the second cyclonic separation chambers is coupled to a conduit having a longitudinal axis, an inlet, an outlet, and a single planar baffle projecting radially inwardly from an interior surface of the conduit towards the longitudinal axis.
A cyclonic separating apparatus, comprising a separating chamber, an inlet communicating with the separating chamber and an outlet, the outlet being formed by a conduit communicating with an interior portion of the separating chamber and having a longitudinal axis, wherein a single planar baffle projects radially inwardly from an interior surface of the conduit towards the longitudinal axis;
- wherein an upstream end of the baffle increases in depth in a direction of flow through the conduit.
A cyclonic separating apparatus, comprising a separating chamber, an inlet communicating with the separating chamber and an outlet, the outlet being formed by a conduit communicating with an interior portion of the separating chamber and having a longitudinal axis, wherein a single planar baffle projects radially inwardly from an interior surface of the conduit towards the longitudinal axis;
- wherein a downstream end of the baffle decreases in depth in a direction of flow through the conduit.
