Definitions

  • 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.
  • a sanitary ware vessel including a fin or ridge with one or more concave side surfaces against which a stream of fluid may be directed.
  • 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.
  • 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.
  • the longitudinal length of the fin or ridge may be substantially centrally positioned between the two sides of the urinal.
  • Fig. 1 shows a perspective view of a urinal with a central raised fin or ridge and a standard waste outlet
  • Fig. 2 shows a plan of a section through the urinal shown in Fig. 1 ;
  • Fig. 3 diagrammatically shows a stream of fluid directed onto a side surface of a fin or ridge
  • Fig. 4 shows a perspective view of an alternative waste outlet in which the ridge feature extends into the waste aperture
  • Fig. 5 shows a plan view of the waste outlet shown in Fig. 4;
  • Fig. 6 shows a perspective view of a urinal with a substantially centrally positioned raised ridge and an asymmetrically positioned waste outlet
  • Fig. 7 shows a perspective view of a conventional urinal bowl with a ridged waste outlet cover
  • Fig. 8 shows a perspective view of the waste outlet cover shown in Fig. 7;
  • Fig. 9 shows a perspective view of the rear of the waste outlet cover shown in Fig. 8.
  • Fig. 10 shows a perspective view of a urinal with a central raised ridge with a waste outlet cover which forms a portion of the ridge;
  • Fig. 1 1 shows a perspective view of the waste outlet cover shown in Fig. 10;
  • Fig. 12 shows a perspective view of a sink with a central raised ridge and a waste outlet positioned behind the ridge;
  • Fig. 13 shows a plan view of the sink shown in Fig. 12 with arrows showing the run-off path for water
  • Fig. 14 shows a side view section through the sink shown in Figs. 12 and 13;
  • 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.
  • 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 1 1 , 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.
  • ⁇ the angle between the stream and side surface and splashing is significantly reduced.
  • 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. 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 the waste outlet 32 further from the front of the urinal as shown in Figure 6 may provide advantages when connecting plumbing to the waste outlet 30. It may be advantageous to provide a raised area on the other side of the fin 10 from that in which the waste outlet 32 is provided with a gradient to enable fluid to run down by gravity from that side to the side with the waste outlet 32. This change in level or gradient will allow fluid to flow due to gravity to the outlet 32.
  • Figure 7 shows a conventional urinal bowl 20 with a waste outlet cover 40 including a ridge or fin 41.
  • the provision of a waste outlet cover 40 with a ridge or fin 41 is a cost-effective way of providing a fin with its associated advantages in a conventional sanitary ware vessel such as a urinal.
  • a waste outlet cover 40 could be provided in any sanitary ware vessel such as a sink or basin.
  • the waste outlet cover 40 could, for example, be a plug for a sanitary ware vessel.
  • Figure 8 shows an enlarged perspective view of the waste outlet cover 40 shown in Figure 7.
  • the waste 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 the waste outlet cover 40 or around the edge of the waste 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 the waste outlet cover 40 to be fitted to the waste outlet as is well known by those skilled in the art.
  • an opening 42 may be provided at the rear of the waste outlet cover 40 as shown in figure 9 to enable fluid to pass through the waste outlet cover 40 to the waste outlet.
  • one or more outlets 43 may be provided in the waste outlet cover 40 as shown in Figure 11 to enable waste fluid to pass through the waste outlet cover 40 to the waste outlet.
  • the outlets 43 are in the form of holes.
  • Figure 10 shows a urinal including a fin wherein a portion of the fin is provided by a fin 10 integral with the urinal and a portion of the fin is provided by a fin 41 provided by a waste outlet cover 40.
  • the fin 10 integral with the urinal extends both above and below the fin 41 provided by the waste outlet cover 40.
  • the fin 10 integral with the urinal could just be provided on one side of the fin 41 provided by the waste outlet cover.
  • the fin provided by both the waste 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.
  • the waste outlet cover 40 may be arranged such that fluids may pass to the waste outlet underneath the waste outlet cover 40 by the provision of a clearance, in use, underneath the waste outlet cover 40 or by a gap between the edge of the waste outlet cover 40 and the neighbouring integral projection 10 or by a gap at the side of the waste outlet cover 40 or by two or more of these.
