Abstract

A fixture fits next to the basin of a sink. The fixture has a water spout arranged to project over the basin of the sink. The water spout has a water nozzle arranged for connection through the spout to a water supply. The fixture further includes an elongate air-knife discharge outlet for discharging an air-knife onto a user'"'"'s hand to dry it. This discharge outlet is arranged for connection to an air supply via an air duct, the air duct having a side wall extending between a first end of the duct and a second end of the duct. The first end of the duct is connected to the air supply, the second end of the duct forms—or is connected to—the air-knife discharge outlet. The outlet extends across the second end of the duct, as opposed to being provided in the sidewall of the duct.

Claims

1. A fixture for fitting next to the basin of a sink, the fixture comprising a water spout arranged to project over the basin of the sink, the water spout having a water nozzle arranged for connection through the spout to a water supply, the fixture further comprising an elongate air-knife discharge outlet for discharging an air-knife onto a user'"'"'s hand to dry it, the discharge outlet being arranged for connection to an air supply via an air duct, the air duct having a side wall extending between a first end of the duct and a second end of the duct, the first end of the duct connecting to the air supply, the second end of the duct forming—

or being connected to—

the air-knife discharge outlet, the air-knife discharge outlet extending across the second end of the duct.

2. The fixture of claim 1, wherein each air-knife discharge outlet comprises an elongate discharge aperture or elongate line of discharge apertures.

3. The fixture arrangement of claim 1, wherein the air-knife discharge outlet comprises an elongate air slot or plurality of elongate air slots.

4. The fixture of claim 3, wherein in which the width of the slot(s) is less than 2 mm.

5. The fixture of claim 1, wherein the air-knife discharge outlet aperture is at least 80 mm long.

6. The fixture of claim 1, comprising two elongate air-knife discharge outlets.

7. The fixture of claim 6, wherein the two air-knife discharge outlets are arranged to extend laterally either side of the water nozzle.

8. An arrangement comprising the fixture of claim 2, the fixture being fitted next to the basin of a sink, the water nozzle being connected to a water supply, the discharge aperture(s) being connected to an air supply arranged for driving airflow through the discharge aperture(s) at an exit velocity in excess of 80 m/s.
