A fan assembly comprising a filter supported on a seat of an upper body section

A fan assembly comprises a body having an air inlet 22, an air outlet 74, and means (e.g. impeller 80) for generating an air flow through the body. The body has lower and upper body sections 52, 50 capable of relative rotation (e.g. oscillation). A nozzle receives and emits the air flow from the bod...

More Information
Summary:A fan assembly comprises a body having an air inlet 22, an air outlet 74, and means (e.g. impeller 80) for generating an air flow through the body. The body has lower and upper body sections 52, 50 capable of relative rotation (e.g. oscillation). A nozzle receives and emits the air flow from the body. A filter (14, figure 12) is provided upstream from the air inlet, and is supported by an upwardly facing surface of a seat (e.g. annular flange 54) on the upper body section, such that the filter rotates relative to the lower body section when the upper body section rotates. The seat may be inclined downwardly away from a longitudinal axis of the body, or may comprise a first section extending perpendicular to the longitudinal axis, and a second section inclined downwardly relative to the longitudinal axis. Wedge shaped projections may taper upwardly and inwardly from an outer edge of the filter towards the longitudinal axis.
