A dual-purpose fixture for a sink or wash basin, incorporating both a water tap and a hand dryer. The water tap has a spout arranged to project over the basin of the sink, and the hand dryer incorporates two or more hand-dryer nozzles&#x2014;at least one for each of a user's hands. The left-hand nozzle is located on the left-hand side of the spout and the right-hand nozzle is located on the right-hand side of the spout, specifically so that the spout acts as a dividing partition between the two hand-dryer nozzles. This encourages correct usage of the hand-dryer. The fixture may be fitted to a sink or wall-mounted above the sink.

Fixture for a sink

A fixture for a sink&#x2014;for example provided in a commercial washroom or the like&#x2014;incorporating a water tap and a hand dryer. The water tap comprises a spout arranged to project over the basin of the sink. The hand dryer comprises: an opposing pair of left-hand nozzles mounted on the spout for directing air onto the front and back of a user's left hand as it is passed&#x2014;with palm open&#x2014;in between the opposing nozzles, and an opposing pair of right-hand nozzles mounted on the spout for directing air onto the front and back of a user's right hand as it is passed&#x2014;with palm open&#x2014;in between the nozzles.

A cleaner head for a vacuum cleaner has a rotating brush bar driven by an air-cooled motor, which is mounted inside the cleaner head with at least a section of the motor being located inside the brush bar. To cool the motor in use, an external casing of the motor is provided a plurality of air-cooling holes comprising at least one air intake and at least one air exhaust. These cooling holes are connected&#x2014;intake to exhaust&#x2014;to form one or more air-cooling paths through the inside of the motor. Each air intake is connected to an upstream clean air inlet by a stationary&#x2014;not rotating&#x2014;intake duct, and each air exhaust is similarly connected to a downstream clean air outlet by a stationary&#x2014;not rotating&#x2014;exhaust duct. This avoids the problems associated with using the rotating brush bar itself as a duct for carrying cooling air to the motor.

Cleaner-head for a vacuum cleaner

A cleaner head for a vacuum cleaner houses a hollow brush bar mounted for rotation about an axis. This brush bar is driven by a motor housed inside the hollow brush bar, the motor forming part of a drive assembly supported at one end of the cleaner head. The brush bar is arranged for removal from the cleaner head by sliding the brush bar along the axis and out through an opening at the opposite end of the cleaner head and the brush bar is rotatably supported in clearance around the drive assembly by a first bearing, which bearing engages the brush bar in a corresponding axial-sliding fit to allow said sliding removal of the brush bar.

Cleaner head for a vacuum cleaner

A cleaner head for a vacuum cleaner has a dirty-air inlet provided in a main suction chamber of the cleaner head, an outlet duct extending from the main suction chamber for connection to a suction source, and a rotating brush bar housed inside the main suction chamber for agitating a floor surface contacted through the dirty-air inlet. The brush bar is driven by an air-cooled motor housed inside a hollow section of the brush bar, the motor having an air intake and an air exhaust fluidly connected to one another to form an air cooling path through the inside of the motor. The air intake is connected to a clean air inlet on the cleaner head and the air exhaust is fluidly connected to the outlet duct by an exhaust duct which bypasses the main suction chamber.
