Definitions
- the present invention is concerned with a nozzle assembly for a faucet, in particular a faucet which separately dispenses water and foam soap.
- Combined faucets are sometimes installed in commercial washrooms, designed so that they are able separately to dispense water and soap over the basin of a sink, as required by the user. This avoids the need for separate stand-alone soap dispensers to be provided in the washroom.

- This differs from the conventional twin-nozzle arrangement in US2007/0152082A1, in which the discharge ends of the water nozzle and the foam soap nozzle are arranged side-by-side, but do not overlap one another.

- the second nozzle may be arranged so that the flared discharge end of the second nozzle overlaps with the discharge end of the first nozzle around the entire perimeter of the second nozzle. This may conveniently be achieved by providing the second nozzle with a conical discharge end, for example.
- the first and second nozzle may share a common partition wall, which may divide the discharge ends of the two nozzles, or at least divide a section of the nozzles.

The nozzle assembly is particularly suitable for faucets designed to dispense water and foam soap separately over the basin of a sink.
Description
- This application claims the priority of United Kingdom Application No. 1215020.7, filed Aug. 23, 2012, the entire contents of which are incorporated herein by reference.
- The present invention is concerned with a nozzle assembly for a faucet, in particular a faucet which separately dispenses water and foam soap.
- ‘Combined’ faucets are sometimes installed in commercial washrooms, designed so that they are able separately to dispense water and soap over the basin of a sink, as required by the user. This avoids the need for separate stand-alone soap dispensers to be provided in the washroom.
- US2007/0152082A1 describes one of these combined faucets. Here, the soap is aerated upstream of the nozzle and dispensed as a foam, rather than in liquid form. This reduces soap usage per use cycle.
- An object of the present invention is to try to provide an improved nozzle assembly for a tap, or faucet. The nozzle assembly is intended primarily for dispensing foam soap and water, although the invention is not limited as such.
- According to the present invention, there is provided a nozzle assembly for a tap, or faucet, the assembly comprising a first nozzle and a second nozzle arranged side by side, the second nozzle having a flared discharge end which flares outwardly in front of the discharge end of the first nozzle so that the two discharge ends overlap.
- The invention provides a relatively compact nozzle assembly, effectively by arranging the second nozzle so that it overlaps in front of the discharge end of the first nozzle. This differs from the conventional twin-nozzle arrangement in US2007/0152082A1, in which the discharge ends of the water nozzle and the foam soap nozzle are arranged side-by-side, but do not overlap one another. The invention thus allows a larger total discharge area to be packaged within a comparable-sized nozzle assembly.
- The discharge end of the second nozzle may be conical (including frusto-conical), but this is not essential.
- The flared discharge end of the second nozzle may be a separate part which fits onto the end of a supply duct forming part of the second nozzle. Thus the discharge end may be interchangeable with other discharge ends to vary the overlap between the discharge ends of the nozzles, according to specification. The discharge end may engage the duct section in a simple push-fit.
- The first nozzle may at least partly surround the second nozzle. For example, the first nozzle may comprise two or more branches extending along opposite sides of the second nozzle: the discharge end of the first nozzle being formed by the respective discharge ends of the different branches. Alternatively, the first nozzle may have an annular discharge end surrounding the second nozzle and the second may project out beyond an outer wall of the annular discharge end of the first nozzle. In any event, the second nozzle may be arranged so that it overlaps in front of the discharge end of the first nozzle on both sides of the second nozzle. This is a particularly compact arrangement. The second nozzle may be arranged so that the flared discharge end of the second nozzle overlaps with the discharge end of the first nozzle around the entire perimeter of the second nozzle. This may conveniently be achieved by providing the second nozzle with a conical discharge end, for example.
- The first and second nozzle may share a common partition wall, which may divide the discharge ends of the two nozzles, or at least divide a section of the nozzles. If the first nozzle has an annular discharge end, then this common partition wall may form the inner wall of the annular discharge end and at the same time constitute an outer wall of the second nozzle. The partition wall may project out beyond the end of an outer wall of the annular discharge end of the first nozzle, in which case the projecting end of the common wall may define the flared discharge end of the second nozzle. Alternatively, the common wall may define a supply duct forming part of the second nozzle, and the discharge end of the second nozzle may be provided as a separate part which fits onto the end of the supply duct.
- The nozzle assembly may be incorporated as part of a self-contained nozzle unit for fitting to a faucet.
- In another aspect of the invention, there is provided a faucet which is fitted with the nozzle unit, or which otherwise comprises the nozzle assembly.
- The faucet may be arranged for separately discharging foam and water. Thus, an arrangement may be provided comprising the faucet, the faucet being arranged for connecting an intake end of the first nozzle to a water supply and for connecting an intake end of the second nozzle to a supply of foam. The faucet may be installed next to the basin of a sink e.g. in a commercial washroom, with the first nozzle connected to a water supply and the second nozzle connected to a supply of foam. The supply of foam may be a supply of foam soap, specifically.
- A relatively large discharge area is particularly beneficial when dispensing foam from a faucet, because users often perceive a voluminous-looking foam product as being rich and luxurious. This is particularly the case for foam soap, and this may be specified in hotels, health clubs etc. At the same time, utilising the invention to provide a relatively compact nozzle assembly allows for incorporation of the nozzle assembly in a more minimalist design of faucet.
- The flared discharge end of the second nozzle advantageously decelerates the foam prior to discharge. A mesh screen may be provided over the discharge end of the second nozzle to act as a turbulator for aerating the decelerating foam immediately prior to discharge. This may improve foam consistency.

FIG. 1 is a two-dimensional representation intended to illustrate the basic concept of the invention. It depicts two nozzles arranged side-by-side. Thefirst nozzle 1 has anopen intake end 3 and anopen discharge end 5. Thesecond nozzle 7 likewise has anopen intake end 9 and anopen discharge end 11. Thedischarge end 11 of the second nozzle is a flared discharge end, which extends outwardly in front of thedischarge end 5 of thefirst nozzle 1. The degree of overlap is given as ΔD.

Each branch has a respective discharge end 19 a, 19 b which together form the discharge end of thefirst nozzle 15. Thesecond nozzle 13 is provided with a symmetric, flareddischarge end 17, which extends outwardly in front of the respective discharge ends 19 a, 19 b of both of thebranches -
FIG. 3 illustrates anozzle 21 unit which incorporates a nozzle assembly according to the present invention. - The nozzle assembly comprises two nozzles: a
foam nozzle 23 for dispensing foam soap and awater nozzle 25 for separately dispensing water. - The
foam nozzle 23 comprises a cylindricalfoam supply duct 27 and a flareddischarge end 29 which push-fits onto the lower end of the supply duct 27 (see alsoFIG. 4 ). - The water nozzle comprises an annular intake manifold 31 (
FIG. 4 ) which extends around the centralfoam supply duct 27 and abasket 33, the open upper end of which clips onto a mountingflange 35 immediately above theintake manifold 31. - The lower end of the
basket 33 forms the discharge end of the water nozzle. It comprises an annular, self-supporting grille orscreen 37, which extends between the outer wall 39 of thebasket 33 and acentral boss 41. - The

The mixing chamber (not shown) is preferably located close to the intake end of thefoam supply duct 27 and is connected to the intake end of thefoam supply duct 27 by aflexible pipe 53, which push-fits on to the end of thefoam supply duct 27. The foam soap thus enters thenozzle unit 21 through the upper end of thefoam supply duct 27, passes down through theduct 27 and then exits through the flareddischarge end 29 of the foam nozzle 23 (seeFIG. 7 ). The foam is expanded as it passes through the flareddischarge end 29, advantageously producing a relatively broad, slow jet of foam soap (represented by the dotted lines inFIG. 7 ). - The water is supplied to the
water nozzle 25 by a conventional mains water supply. The water enters thenozzle unit 21 through a series of inlet ports (not visible) on top of the flow regulator and passes via the flow regulator to the interior of theintake manifold 31.
