Definitions
- the present invention relates to a splash reducing device for a sanitary ware vessel such as a urinal, sink or basin for example.
- a stream of fluid is directed into a sanitary ware vessel such as a urinal, sink or basin, at least a portion of the fluid will rebound as splash. This splash is likely to rebound onto the user and the surrounding area. This is particularly undesirable for urinals where the splash is unhygienic, can lead to washroom odours, can damage the floor and wall panels and is unpleasant for the user.
- a sanitary ware vessel including a central raised fin or ridge with one or more concave side surfaces against which a stream of fluid may be directed, wherein the longitudinal length of the fin or ridge is arranged in a substantially vertical plane, the sanitary ware vessel further comprising a waste outlet having a waste outlet cover, wherein the central raised fin or ridge comprises a first portion provided by a fin or ridge integral with the sanitary ware vessel and a second portion provided by a fin or ridge provided by the waste outlet cover so as to form a continuous fin or ridge.
- At least a portion of the side surface is preferably at less than 90° or at a relatively shallow angle to the stream of fluid such that splashing is significantly reduced. It has been found that any splashing will occur at a similarly shallow angle away from the direction of flow and the user and that the fluid will cling to the side surface of the fin or ridge against which it is directed due to surface tension. Thus splashing is significantly reduced when compared to fluid directed substantially perpendicularly against a surface as in conventional sanitary ware vessels such as urinals, sinks and basins for example.
- At least a portion of the side surface of the fin or ridge is preferably arranged such that a stream of fluid may be directed towards it at an angle of less than 80°, less than 70°, less than 60°, less than 50°, less than 40°, less than 30°, less than 20° or less than 10° between the side surface and the stream of fluid.
- sanitary ware vessel which is a sink or urinal and also to a toilet bowl or WC or a waste outlet cover incorporating the essential features of the invention.
- the urinal preferably has the longitudinal length of the fin or ridge arranged in a substantially vertical plane.
- German Patent DE 19704739 discloses a urinal with or without a flushing device.
- a tube stands vertically with a closed cover-type head part upwards.
- a longitudinal slot is available as a urine output aperture.
- the width at the longitudinal slot is smaller than the internal width of the urinal body so that to the side of the longitudinal slot extending wall sections are available which enclose the inner space of the urinal body.
- German Patent DE 1814125 refers to a combination of elements for the structure of a bank of urinals which meets hygienic and other needs.
- UK Patent GB 1,402,315 discloses a urinal having a waste outlet and means located above the waste outlet for discharging water from an outlet onto a surface of the urinal which extends upwardly from the waste outlet towards the outlet of the water discharge means.
- US Patent No. US5005224 relates to a toilet bowl silencer dish.
- UK Patent GB1,304,372 relates to a moulded plastics toilet pot.
- German Utility Model DE 8023199 U relates to washstand and can be considered as the closest prior art for the subject matter of claim 1.
- a ridge or fin 10 is provided in a sanitary ware vessel, in this example a urinal 20.
- the sanitary ware vessel, in this example the urinal 20 has a peripheral edge 21 within which the fin or ridge 10 is provided.
- the fin 10 is also clearly seen in the sectional view of Figure 2 .
- the front edge of the fin 10 is provided within a vertical plane with the side surfaces 11, 12 of the fin curving to meet the rear surface 22 of the urinal.
- the side surfaces 11, 12 of the fin 10 need not curve but could be flat and meet the rear surface 22 of the urinal at a corner (not shown).
- a stream of fluid 13 is directed onto one or both sides 11, 12 of the fin 10 as diagrammatically shown in Figure 3 .
- the stream of fluid encounters the side surface 11, 12 with a relatively shallow or small angle ⁇ of less than 90° between the stream and side surface and splashing is significantly reduced. As explained above, this is because any splashing will occur at a similarly shallow angle away from the direction of flow and the user and because fluid will cling to the side surface 11, 12 due to surface tension.
- a waste outlet 30 is shown in the urinal 20.
- the waste outlet 30 has a circular cross-section.
- the fin 10 could extend into a waste outlet 31. This enables the front, lower end of the fin 10 to extend further towards the front of the urinal so that it can act on a stream of fluid which does not extend far into the urinal, whilst still providing a waste outlet 31 of adequate size.
- the waste outlet 30 is shown positioned substantially centrally between the two sides of the urinal.
- a waste outlet 32 could be provided to one side of the fin 10.

Description
- The present invention relates to a splash reducing device for a sanitary ware vessel such as a urinal, sink or basin for example.
- If a stream of fluid is directed into a sanitary ware vessel such as a urinal, sink or basin, at least a portion of the fluid will rebound as splash. This splash is likely to rebound onto the user and the surrounding area. This is particularly undesirable for urinals where the splash is unhygienic, can lead to washroom odours, can damage the floor and wall panels and is unpleasant for the user.
- It is an aim of the present invention to reduce the amount of splash produced when a stream of fluid is directed into a sanitary ware vessel. Aspects of the invention are defined in the accompanying claims.
- According to a first aspect of the present disclosure there is provided a sanitary ware vessel including a central raised fin or ridge with one or more concave side surfaces against which a stream of fluid may be directed, wherein the longitudinal length of the fin or ridge is arranged in a substantially vertical plane, the sanitary ware vessel further comprising a waste outlet having a waste outlet cover, wherein the central raised fin or ridge comprises a first portion provided by a fin or ridge integral with the sanitary ware vessel and a second portion provided by a fin or ridge provided by the waste outlet cover so as to form a continuous fin or ridge.
- In use at least a portion of the side surface is preferably at less than 90° or at a relatively shallow angle to the stream of fluid such that splashing is significantly reduced. It has been found that any splashing will occur at a similarly shallow angle away from the direction of flow and the user and that the fluid will cling to the side surface of the fin or ridge against which it is directed due to surface tension. Thus splashing is significantly reduced when compared to fluid directed substantially perpendicularly against a surface as in conventional sanitary ware vessels such as urinals, sinks and basins for example.
- At least a portion of the side surface of the fin or ridge is preferably arranged such that a stream of fluid may be directed towards it at an angle of less than 80°, less than 70°, less than 60°, less than 50°, less than 40°, less than 30°, less than 20° or less than 10° between the side surface and the stream of fluid.
- Aspects of the disclosure extend to a sanitary ware vessel which is a sink or urinal and also to a toilet bowl or WC or a waste outlet cover incorporating the essential features of the invention.
- The urinal preferably has the longitudinal length of the fin or ridge arranged in a substantially vertical plane.
- German Patent

Fig. 15 shows splashing resulting from dropping fluid onto a flat surface and; -
Fig. 16 shows splashing resulting from dropping fluid onto a fin or ridge. - As shown in
Figure 1 , a ridge orfin 10 is provided in a sanitary ware vessel, in this example a urinal 20. The sanitary ware vessel, in this example the urinal 20, has aperipheral edge 21 within which the fin orridge 10 is provided. Thefin 10 is also clearly seen in the sectional view ofFigure 2 . In this example the front edge of thefin 10 is provided within a vertical plane with theside surfaces rear surface 22 of the urinal. However, theside surfaces rear surface 22 of the urinal at a corner (not shown). - In use, a stream of
fluid 13 is directed onto one or bothsides fin 10 as diagrammatically shown inFigure 3 . By directing the stream offluid 13 on to thesides fin 10, the stream of fluid encounters theside surface side surface - A
waste outlet 30 is shown in theurinal 20. In the example shown inFigures 1 and 2 thewaste outlet 30 has a circular cross-section. However, as shown inFigures 4 and 5 , thefin 10 could extend into awaste outlet 31. This enables the front, lower end of thefin 10 to extend further towards the front of the urinal so that it can act on a stream of fluid which does not extend far into the urinal, whilst still providing awaste outlet 31 of adequate size. - In
Figures 1 and 2 thewaste outlet 30 is shown positioned substantially centrally between the two sides of the urinal. However, as shown inFigure 6 , awaste outlet 32 could be provided to one side of thefin 10. This also enables the front, lower end of the fin to extend further towards the front of the urinal so that it can act on a stream of fluid which does not extend far into the urinal, whilst still providing a waste outlet of adequate size. Positioning thewaste outlet 32 further from the front of the urinal as shown inFigure 6 may provide advantages when connecting plumbing to thewaste outlet 30. It may be advantageous to provide a raised area on the other side of thefin 10 from that in which thewaste outlet 32 is provided with a gradient to enable fluid to run down by gravity from that side to the side with thewaste outlet 32. This change in level or gradient will allow fluid to flow due to gravity to theoutlet 32. -
Figure 7 shows a conventionalurinal bowl 20 with awaste outlet cover 40 including a ridge orfin 41. The provision of awaste outlet cover 40 with a ridge orfin 41 is a cost-effective way of providing a fin with its associated advantages in a conventional sanitary ware vessel such as a urinal. Although not shown, such awaste outlet cover 40 could be provided in any sanitary ware vessel such as a sink or basin. Thewaste outlet cover 40 could, for example, be a plug for a sanitary ware vessel. -
Figure 8 shows an enlarged perspective view of thewaste outlet cover 40 shown inFigure 7 . Thewaste outlet cover 40 may be arranged such that when it is fitted to a sanitary ware vessel such as a urinal there is a clearance or gap below thewaste outlet cover 40 or around the edge of thewaste outlet cover 40 or both to enable fluid to pass to the waste outlet. The clearance or gap would be provided by the appropriate arrangement of a mount for thewaste outlet cover 40 to be fitted to the waste outlet as is well known by those skilled in the art. Alternatively or additionally anopening 42 may be provided at the rear of thewaste outlet cover 40 as shown infigure 9 to enable fluid to pass through thewaste outlet cover 40 to the waste outlet. Alternatively or additionally, one ormore outlets 43 may be provided in thewaste outlet cover 40 as shown inFigure 11 to enable waste fluid to pass through thewaste outlet cover 40 to the waste outlet. In this example theoutlets 43 are in the form of holes. -
Figure 10 shows an embodiment of the present invention wherein the sanitary ware vessel is in form of a urinal including a fin wherein a portion of the fin is provided by afin 10 integral with the urinal and a portion of the fin is provided by afin 41 provided by awaste outlet cover 40. In this example thefin 10 integral with the urinal extends both above and below thefin 41 provided by thewaste outlet cover 40. However, thefin 10 integral with the urinal could just be provided on one side of thefin 41 provided by the waste outlet cover. The fin provided by both thewaste outlet cover 40 and one or more projections integral with the urinal forms a continuous fin or ridge. Such a fin is able to extend towards the front of the urinal so that it can act on a stream of fluid which does not extend far into the urinal, whilst still providing a waste outlet of adequate size which can be positioned at a suitable distance into the urinal for straightforward plumbing. Thewaste outlet cover 40 may be arranged such that fluids may pass to the waste outlet underneath thewaste outlet cover 40 by the provision of a clearance, in use, underneath thewaste outlet cover 40 or by a gap between the edge of thewaste outlet cover 40 and the neighbouringintegral projection 10 or by a gap at the side of thewaste outlet cover 40 or by two or more of these. The clearance or gap would be provided by the appropriate arrangement of a mount for thewaste outlet cover 40 to be fitted to the waste outlet as is well known by those skilled in the art. Alternatively or additionally anopening 42 may be provided at the rear of thewaste outlet cover 40 as shown infigure 9 to enable fluid to pass through thewaste outlet cover 40 to the waste outlet. Alternatively or additionally, one ormore outlets 43 may be provided in thewaste outlet cover 40 as shown inFigure 11 to enable waste fluid to pass through thewaste outlet cover 40 to the waste outlet. In this example theoutlets 43 are in the form of holes. - The urinal shown in the Figures described above is made from slip-cast vitreous china and the fin shown in
Figures 1 to 6 and10 is also made from slip-cast vitreous china. However, the urinal or fin or both could be made from any suitable material such as plastics, slip-cast vitreous china, metal or any combination thereof for example. Thewaste outlet cover 40 shown inFigures 7 to 11 may be made from any suitable material such as a plastics material, a metal, slip-cast vitreous china or a combination of materials. - Not in the sense of the present invention, a ridge or fin with one or more side surfaces against which a stream of fluid may be directed may be retro fitted to a sanitary ware vessel. The ridge or fin may be retro fitted to a sanitary ware vessel in any suitable way well known to those skilled in the art such as by using an adhesive or by fitting the ridge or fin to a structure on the sanitary ware vessel such as a flushing outlet or a drilled hole. A ridge or fin may be retro-fitted to a urinal, sink or basin for example.
-
Figures 12 to 14 show a sink with the splash reducing feature. - As shown in
Figure 12 , thesink 50 may be attached to a wall (not shown) at itsrear side 51 and a tap (not shown) may be provided to direct a fluid, generally water, into thesink 50 from above. A projection, fin orridge 52 is provided in thesink 50. Thefin 52 has side surfaces 53, 54 against at least one of which a stream of water is directed, in use, from the tap. As the stream of water is directed onto the side surfaces 53, 54 with a relatively shallow or small angle between the stream and side surface, splashing is significantly reduced. As explained above, this is because any splashing will occur at a similarly shallow angle away from the direction of flow and the user and because fluid will cling to the side surfaces 53, 54 due to surface tension. This is in contrast to conventional sinks in which fluid from a tap directs water substantially perpendicularly against the lower surface of the sink. - Fluid is preferably directed to
side surface 54 offin 52 facing away from the user to further reduce the likelihood of splashing onto the user or surrounding areas. -
Figure 13 is a plan view of the sink shown inFigure 12 and includes arrows showing the run off path for water received in the sink towardswaste outlet 55. As shown inFigure 13 , thesink 50 is arranged such that, in use, the height of the surface of the sink reduces towards thewaste outlet 55 to allow the free flow of water. - The
fin 52 shown inFigures 12 to 14 is curved along its length and so may be used with a tap which is pivoted such that whatever position the pivoted tap is moved to, the stream of water will engage aside surface fin 52 and reduce splashing. The dimensions of the curve of thefin 52 are preferably selected to correspond to the positions into which a tap may be pivoted. The curve of the fin is generally an arc of a circle. - As with the urinal described above, although the
sink 50 shown inFigures 12 to 14 is made from slip-cast vitreous china, the sink could be made from any suitable material such as metal for example or a combination of materials. If desired thefin 52 could be retro fitted to the sink. - In order to illustrate the efficacy of the ridge or fin described above in reducing splashing, a demonstration was prepared which is described below. First, in order to demonstrate splashing from a conventional sanitary ware vessel, a flat surface was provided and a sheet of blotting paper was provided in a circular manner around its periphery. A predetermined quantity of diluted black ink was then dropped from a predetermined height above onto the flat surface at a predetermined rate. Splashes were recorded by the diluted black ink rebounding from the flat surface and marking the blotting paper.
Figure 15 shows the resultant blotting paper after being tested with a flat surface representing a conventional sanitary ware vessel such as a urinal or sink. The demonstration was then repeated using a ridge with a cross-section equivalent to that of the fin shown inFigure 3 with the same quantity of diluted black ink dropped onto a side surface of the fin from the same height and at the same rate as before.Figure 16 shows the resultant blotting paper after being tested with a fin. As can be clearly seen, the amount of splashing is significantly reduced by use of the fin. - The terms fin, ridge and projection may be used interchangeably in the examples described above.
- Many variations may be made to the examples described above whilst still falling within the scope of the present invention.
