Technical Field

The present invention relates to a showerhead. More particularly, but not exclusively, the invention relates to a spray head in the form of a shower head.

Background

Shower heads typically comprise a housing having a plurality of nozzles in a lower surface of the housing, which nozzles generate a stream of water droplets in use. One such shower head is disclosed in the international (PCT) patent publication No. WO 2013/141719. However, a problem with existing shower heads is that they may not produce a satisfactory spray of water droplets at low flow rates.

It is an object of the present invention to provide a spray head and/or shower head which overcomes or at least ameliorates one or more problems of existing spray heads/shower heads, or at least provides a useful alternative.

Detailed Description

It will be understood that the invention disclosed and defined in this specification includes all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the present invention.

Referring to fig. 1, a photograph of a showerhead according to a first embodiment of the present invention is shown. The spray head is in the form of a shower head 10 for showering, however the spray head described herein may alternatively be in the form of a hand shower or other similar spray head.

Referring to fig. 2, the showerhead 10 includes a generally cylindrical housing 12, a central inlet 14 for receiving a fluid, particularly water, from a fluid conduit connected to a water supply (not shown), and a plurality of nozzles 18 (fig. 3), the plurality of nozzles 18 being disposed in a base 20 of the housing 12. Each of the plurality of nozzles 18 is adapted to generate, in use, a continuous jet of fluid 22 (fig. 1) having an elongate transverse cross-section. Each fluid jet 22 is "continuous" in terms of substantially the entire body of fluid.

As shown in fig. 1, each fluid jet 22 flares outwardly from a respective nozzle 18, thus assuming a generally "bell" shape in lateral cross-section. The nozzles 18 of the showerhead 10 are configured so that each fluid jet 22 or body does not disperse into discrete droplets until about 30mm from the base 20 of the showerhead. It has been found that this flow pattern produces a satisfactory spray even at lower water flow rates.

Fig. 2 is a top perspective view of showerhead 10 showing generally cylindrical housing 12 and central inlet 14 of the showerhead. Fig. 3 is a bottom perspective view of showerhead 10 showing a plurality of nozzles 18 arranged circumferentially equidistant from one another about a base 20 of housing 12. As shown in fig. 3, the showerhead 10 includes fifteen such nozzles 18. However, the skilled person will appreciate that the number and arrangement of nozzles may be varied without departing from the scope of the invention.

Fig. 4A is a close-up perspective view of a single nozzle 18 of the plurality of nozzles. Each of the plurality of nozzles 18 has the same form and size. As shown in fig. 4A and 4C, the nozzle 18 has an elongated transverse cross-section 24 generally in the form of a diamond with a curved apex. The elongate transverse cross-section 24 defines a long (or transverse) axis 26 of about 6.5mm in length and a short axis 28 of about 7.5mm in length. Those skilled in the art will appreciate that these lengths are merely exemplary and that slight variations in these lengths will only result in a change in the angle of opening of the outgoing fluid (as described below).

As shown more clearly in fig. 4B, the nozzle 18 defines a nozzle opening 30, the nozzle opening 30 being curved (or convex) outwardly along the long (or transverse) axis 26 relative to the base 20 of the housing 12. When in use, the elongated transverse cross-section 24 of the nozzle 18 and the outwardly curved nozzle opening 30 together are adapted to produce a continuous fluid jet 22 having the same elongated transverse cross-section, which in lateral cross-section is in the form of a general "bell". As shown particularly in fig. 4D, each nozzle 18 is also slightly angled inwardly toward a central portion 32 (fig. 1) of the base 20 of the showerhead 10 at an angle of inclination of about 6.5 °.

The showerhead 10 also includes a recess 40 disposed about each nozzle opening 30. In a manner described below, the recess 40 is configured to define an angle of opening of the fluid jet 22 exiting the nozzle 18. As shown in fig. 4A and 4B, the recess 40 extends into the base 20 around the outwardly curved nozzle opening 30. The recess 40 includes a base 41, a first pair of opposing sides 42 extending from the base 41, and a second pair of opposing sides 44 extending from the base 41. The first pair of opposing sides 42 is generally perpendicular to the long (or transverse) axis 26 (and generally parallel to the short axis 28) of the nozzle 18. The second pair of opposing sides 44 are generally parallel to the long (or transverse) axis 26 of the nozzle 18 (and generally perpendicular to the short axis 28). As particularly shown in fig. 4B, the first pair of opposing sides 42 diverge outwardly at a similar angle toward the base of the spray head 20 from a position immediately adjacent to the opposing longitudinal ends 46 of the nozzle opening 30. Thus, the outwardly diverging sides 42 define the angle of divergence of the fluid jet 22 exiting the nozzle opening 30. The opening angle is about 46 °. In an alternative embodiment of the spray head, not shown, the opening angle may be about 22 °.

Fig. 5 is a cross-sectional view of the showerhead 10 showing a plurality of fluid conduits 50, the plurality of fluid conduits 50 being in fluid communication with the inlet 14 via a generally cylindrical interior chamber 52 disposed below the inlet 14 in the housing 12. Each fluid conduit of the plurality of fluid conduits 50 is in fluid communication with a respective one of the plurality of nozzles 18. In this way, water entering the inlet 14 via a water supply (not shown) is directed to the nozzle 18 via the respective fluid conduit 50. As shown in fig. 5, the plurality of fluid conduits 50 extend generally radially outward from the cylindrical interior chamber 52, and the plurality of fluid conduits 50 are arranged equidistant from one another. The showerhead 10 includes fifteen such fluid conduits 50.

Referring to fig. 6A and 6B, each of the fluid conduits 50 includes a first conduit section 60, a second conduit section 62 downstream of the first conduit section 60, and a third conduit section 64 downstream of the second conduit section 62, the third conduit section 64 defining the nozzle 18. In this context, "downstream" refers to the direction of fluid flow from the inlet 14 to the nozzle opening 30.

The first conduit section 60 has a constant circular cross-section with a diameter of about 4mm and a first conduit length of about 41 mm. In an alternative embodiment, not shown, of the spray head in the form of a handshower, the first conduit may be about 31mm in length. The first conduit section 60 transitions into a second conduit section 62 at the downstream end of the first conduit section. The second conduit section 62 has a converging "conical" cross-section that converges downstream toward the third conduit section 64, and the second conduit section 62 is configured to accelerate fluid flowing toward the third conduit section 64 or nozzle 18. The second conduit section 62 has a second conduit length of about 8 mm. The second conduit section 62 transitions into the third conduit section 64 via a circular aperture 66 arranged at the downstream end of the second conduit section. The diameter of the circular opening 66 is about 1 mm. The third conduit section 64 defines a longitudinal axis that is substantially perpendicular to the longitudinal axes of the first and second conduit sections 60, 62.

The third conduit section 64 includes a curved outer water guiding surface 70 that curves outwardly and downwardly from the circular bore 66 toward the nozzle opening 30 and is configured to guide water in the third conduit section 64 toward the nozzle opening 30. The nozzle opening 30 terminates the third conduit section 64.

In contrast to the discrete water droplet flow that may occur in other showerheads of the prior art, the curved outer water guiding surfaces 70 of the first, second and third fluid conduit sections 60, 62 and 64, and in particular the circular aperture 66 of the second and third fluid conduit sections 62 and 64, are constructed and arranged so as to produce a continuous body or jet of fluid at the nozzle opening 30.

Fig. 7 and 8 show a spray head according to a second embodiment of the present invention. The spray head is in the form of a shower head 100, however the spray head may alternatively be in the form of a hand shower or other similar spray head.

Showerhead 100 is substantially similar to showerhead 10 shown in fig. 1-6, and showerhead 100 includes substantially all of the features described above with respect to showerhead 10, but showerhead 100 also has additional features as described below.

The showerhead 100 includes a housing 112, the housing 112 defining a plurality of fluid conduits 50 (one of which is shown in fig. 7) extending radially outward from a central inlet 114 and arranged equidistant from one another. The showerhead 100 also includes a plurality of nozzle bodies 118, each of the plurality of nozzle bodies 118 being connectable to a respective one of the plurality of fluid conduits 150 for fluid communication therewith.

Each nozzle body 118 includes a first conduit section 160, a second conduit section 162, and a third conduit section 164. The first conduit section 160 has a constant circular cross-section and is configured to fluidly connect to the conduit 150. The first conduit section 160 transitions into the second conduit section 162 at the downstream end of the first conduit section. The second conduit section 162 has a converging "conical" cross-section that converges downstream toward the third conduit section 164, and the second conduit section 162 is configured to accelerate fluid flowing toward the third conduit section 164. The third conduit section 164 terminates with the nozzle opening 130. The third conduit section 164 defines a longitudinal axis that is approximately perpendicular to the longitudinal axis of the second conduit section 162.

Each nozzle body 118 can be removably inserted into housing 112 of spray head 110 by press fitting into housing 112. Each nozzle body 118 also includes a stop (not shown) on an outer surface thereof to limit movement of the body 118 relative to the housing 112 when the body 118 is inserted into the housing 112.

Referring to fig. 8A and 8B, it can be seen that nozzle 118 is similar in many respects to nozzle 18, including: the nozzle openings 130 have an elongated transverse cross-section in the general form of a diamond. However, the nozzle 118 includes a nozzle wall 180 that extends from adjacent the base 141 of the recess 140 to define the nozzle opening 130. Similar to nozzle 18, nozzle 118 has a nozzle opening 130, which nozzle opening 130 is curved (or convex) outwardly relative to a base 141 of recess 140.

The nozzle wall 180 is configured such that the nozzle wall 180 has a maximum height at the longitudinal center and the lateral center of the nozzle opening 130. The height of the nozzle wall 180 tapers outwardly from the longitudinal center and the transverse center such that the nozzle wall 180 has a minimum height at the opposite longitudinal ends 146 of the nozzle opening 130. The nozzle wall 180 defines an edge 182 surrounding the nozzle opening 180. The edge 182 is configured to reduce or prevent fluid from dripping from the nozzle 118 when not in use. Similar to nozzle 18, nozzle 118 includes a first pair of opposing sides 142 and a second pair of opposing sides 144 extending from adjacent base 141 of recess 140, wherein first pair of opposing sides 142 diverge outwardly toward the base of spray head 120 to define a spread angle of the fluid jet.

Nozzle body 118 also includes two spaced apart circumferential recesses positioned about first conduit section 160 that are sized to receive O-rings 190, respectively. O-ring 190 is configured to sealingly connect first conduit section 160 of nozzle body 118 to fluid conduit 150 of the spray head. As noted above, the flow patterns produced by showerhead 10 and showerhead 100 of the present invention have been found to be a satisfactory alternative to the flow patterns produced by other showerheads of the prior art.

It will be understood that the invention disclosed and defined in this specification includes all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the present invention.
