  • FAN
    Publication number: 20130336771
    Abstract: A ceiling fan includes an annular nozzle having an inner wall, an outer wall extending about the inner wall, an air inlet for receiving an air flow, an air outlet for emitting the air flow, and an interior passage located between the inner wall and the outer wall for conveying the air flow to the air outlet. The inner wall defines a bore through which air from outside the nozzle is drawn by the air flow emitted from the air outlet. The fan includes a support assembly for supporting the nozzle on a ceiling. The nozzle is rotatable relative to the support assembly about a rotational axis and between a first orientation in which the air flow is directed away from the ceiling and a second orientation in which the air flow is directed towards the ceiling.

The inner wall defines a bore through which air from outside the nozzle is drawn by the air flow emitted from the air outlet. A support assembly supports the nozzle on a ceiling and includes a ceiling mount for mounting the ceiling fan on a ceiling, an arm having a first end connected to the ceiling mount, and a body connected to a second end of the arm and the annular nozzle. The body is pivotable relative to the arm about a pivot axis to move the annular nozzle between a raised and lowered position.

  • FAN
    Publication number: 20130017104
    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.

  • FAN
    Publication number: 20130017105
    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.

  • FAN
    Publication number: 20130017106
    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.

  • Patent number: 8272098
    Abstract: A vacuum cleaner has a hose and wand assembly onto which a floor tool may be attached. The wand includes a plurality of telescoping tubes which can slide between retracted and extended positions. In order to be able to transmit power and signals from the vacuum cleaner to the end of the wand assembly, conductors are provided in a channel in the hose. The hose is connected to the interior of the wand, just beyond the last telescoping joint, with the conductors extending beyond the end of the hose to a connector at the far end of the wand. This arrangement automatically provides a reliable electrical connection down the wand. Previously, electrical conductors were not employed with this type of wand as it was not straightforward to provide electrical connections across the telescoping parts.

  • Publication number: 20100095474
    Abstract: A vacuum cleaner has a hose and wand assembly, onto which a floor tool may be attached. Power and signals are transmitted down electrical conductors in the hose. In order to permit free movement of the hose, the hose is divided into portions having a joint therebetween. Conductors of one hose portion terminate in contact anus in the joint. The contact arms are in sliding intimate contact with slip rings. The slip rings are connected to conductors of the other hose portion. Thus, the hose portions may rotate relative to one another without causing damage to the electrical connection along the hose.
