Abstract

An arrangement incorporates a sink and a hand dryer which extends over the sink. The hand dryer is of the type which uses an air-knife mechanically to wipe the water from the user's hands. The hand dryer comprising two elongate air-knife discharge outlets—each outlet discharging a respective air-knife forwardly onto a hand of the user—the air-knife outlets being arranged side-by-side over the basin of the sink. Each air-knife outlet extends along a part of the hand dryer which is swept back at an angle such that the inboard end the air-knife outlet is in front of the outboard end of the air-knife outlet.

First claim

The invention claimed is:

1. An arrangement comprising a sink and a hand dryer which extends over the sink and a water faucet which extends over the sink, the hand dryer configured to use an air-knife mechanically to wipe the water from the user's hands, the hand dryer comprising two elongate air-knife discharge outlets—each outlet discharging a respective air-knife forwards onto a hand of the user—the air-knife discharge outlets are provided on a fixture in the form of a spout and are connected through the spout to an air supply, and the air-knife discharge outlets are arranged side-by-side over the basin of the sink, each air-knife outlet being arranged on an angle such that the inboard end the air-knife outlet is in front of the outboard end of the air-knife outlet.

2. The arrangement of claim 1 , wherein the outlets additionally extend downwardly at an anhedral angle so that the inboard end of each air-knife discharge outlet is above the outboard end of the air-knife discharge outlet.

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

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

5. The arrangement of claim 4 , wherein the width of the slot(s) is less than 2 mm.

6. The arrangement of claim 1 , wherein each air-knife discharge outlet is at least 80 mm long.

7. The arrangement of claim 1 , wherein the water faucet has a water delivery nozzle positioned in-between the two air-knife discharge outlets.

8. The arrangement of claim 7 , wherein the water delivery nozzle and air-knife discharge outlets are provided on a single fixture that can be fitted next to the basin of the sink, the water delivery nozzle and air-knife discharge outlets each being provided on a projecting part of the fixture.

9. The arrangement of claim 7 , wherein the water delivery nozzle and the air-knife discharge outlets are provided on a common projecting part of the fixture in the form of a spout.

10. The arrangement of claim 9 , wherein the water delivery nozzle is connected through the spout to a water supply.

11. The arrangement of claim 1 , wherein the air-knife discharge outlets are provided on branch ducts that branch off from a main air supply duct inside the spout, each air-knife discharge outlet extending along a sidewall of the respective branch duct.

12. The arrangement of claim 11 , wherein the branch ducts are swept back at said angle relative to the spout.
