Abstract: There is provided a method of controlling a direction of an airflow emitted from a fan assembly, the fan assembly being capable of changing the direction of the airflow emitted therefrom to any direction within a range of adjustment of the fan assembly. The method comprises receiving user inputs that select an angle of oscillation and that determine a central emission direction for the airflow emitted from the fan assembly, and controlling the emission direction of the fan assembly such that the emitted airflow oscillates through the selected angle of oscillation with the oscillation of the emitted airflow being centered at the central emission direction.

Abstract: A fan assembly for generating an air flow within a room includes an annular casing which defines an interior passage. The interior passage includes an air inlet, and houses, downstream from the air inlet, an impeller and a motor for driving the impeller to draw an air flow through the air inlet and into the fan assembly. The interior passage also has an air outlet from which at least a portion of the air flow is emitted from the fan assembly. The annular casing defines a bore about which the interior passage extends and through which a secondary air flow from outside the fan assembly is drawn by the air emitted from the air outlet.

Abstract: A fan assembly for generating an air flow within a room includes an impeller and a motor for driving the impeller to draw an air flow into the fan assembly, and a casing having an interior passage with a scroll section having a cross-sectional area that decreases from a scroll inlet section to a scroll outlet section. The scroll inlet section has an inlet port for receiving the air flow and the scroll outlet section has an outlet port for returning a first portion of the air flow to the scroll inlet section. The scroll section includes an air outlet for emitting a second portion of the air flow from the casing. The casing defines a bore through which air from outside the fan assembly is drawn by the air emitted from the air outlet.

Abstract: A fan assembly for generating an air flow within a room includes an impeller and a motor for driving the impeller to draw an air flow into the fan assembly, and a casing having a continuous interior passage with a tangential air inlet through which the air flow enters the interior passage and at least one air outlet for emitting at least a portion of the air flow. The casing defines a bore about which the interior passage extends and through which air from outside the fan assembly is drawn by the air emitted from said at least one air outlet.
