In the drawings like references refer to like or comparable parts.
With reference to Figure 1 a bathroom is indicated at 2 having walls 4 and 6, a floor 8, a bath 10 with a rim 12, a bath enclosure 14, and, over the bath, a shower head 16 adjustably mounted in known manner on a rail
<Desc/Clms Page number 8>
18 on the wall 6 and supplied with shower water through a flexible hose 20.
A water temperature control is indicated 22 and is used in a system supplying hot washing water to the bath 10 and the shower 16. The water temperature control 22 may be disposed remotely from the bath and (for example in Figure 1, under the floor) preferably under conditions which may deter or does not easily admit tampering with the water temperate control. The water temperature control 22 has a hot water inlet 24 connected to a pipe 26 from a suitable supply of hot water at an appropriate temperature. The control 22 also has a cold water inlet 28 connected to a pipe 30 from a suitable supply of cold water, for example the mains. Also the control has a bath water outlet 32 connected to a bath water pipe 34, and a shower water outlet 36 connected to a shower water pipe 38. The outlets 32 and 36 are separate and independent, as are the pipes 34 and 38.
The water temperature control 22 is shown in more detail in Figures 8 and 9 and comprises a body 40. Body 40 comprises a hot water manifold 42 supplied through water filter 46 via the hot water inlet 24 and a cold water manifold 44 supplied through another water filter 46 via the cold water inlet 28, both these inlets including a respective normally open isolation valve 48 whereby the system downstream of the isolation valves can be isolated for the hot and cold water supplies by closure of the isolation valves in the event that any said downstream part of the system requires repair or maintenance. The hot water manifold 42 and the cold water manifold 44 each open into respective opposed entrances, through respective check valves 50, to a flow path 52 comprising a bath water thermostatic mixing valve 54 and the bath water outlet 32 from the mixing valve. Also the hot water manifold 42 and the cold water manifold each open into respective opposed entrances, through respective check valves
<Desc/Clms Page number 9>
56, to a flow path 58 comprising a shower water thermostatic mixing valve 60 and the shower outlet 36 from the mixing valve. Two flow paths 52 and 58 are wholly separate and independent one from the other. Each of the thermostatic mixing valves 54 and 60 may be variably settable and the valve 54 may be selectively set to deliver mixed hot bath water at a desired predetermined temperature, for example substantially 43OC, to the bath water outlet 32, whilst the valve 60 may be independently set to deliver mixed hot shower water at a desired predetermined temperature,
for example a temperature in a range of substantially 40 C to substantially 430C to the shower water inlet 36. The mixed hot bath water and the mixed hot shower water are each separately and independently conveyed to the bath 10 and shower 16 along the separate independent bath water pipe 34 and the shower water pipe 38. The water flow may be caused for example by respective pumps or by hydrostatic pressure. The pipes 34 and 38 are respectively connected to a water volume supply control unit 62 shown in Figure 1 mounted or clamped on the bath rim 12 at the front end of the bath 10.
The water volume supply control unit 62 is illustrated in further detail in Figures 2 and 3 and comprises a body 64 containing a bath water conduit 66 terminating in an outlet nozzle or bath spout 68 over the bath 10 and supplied with hot mixed bath water from the pipe 34 connected to water inlet 70 from which the inflow of bath water is regulated by an openable and closeable bath water control valve 72 operated by rotatable knob 74 which in Figures 2 and 3 is substantially vertical. Independent and separate from the bath water conduit 66 is a shower water conduit 76 in the unit body 64. This shower water conduit 76 terminates in a shower water outlet nozzle 78 connected in Figure 1 to the shower hose 20. The shower water conduit 76 which may comprise a check valve 80, is supplied with hot mixed shower water from the pipe 38 connected to a water inlet 82 from which the inflow of shower water regulated by an
<Desc/Clms Page number 10>
openable and closeable shower water control valve 84 operated by rotatable knob 86.
When one desires a bath one merely opens the valve 72 using knob 74 and the bath 10 fills (at a rate corresponding with the extent valve 72 is open) with hot water mixed bath water from the temperature control 22 at the predetermined bath water temperature. Should one desire water to issue from the shower head 16, one merely opens the valve 84 using knob 86 and the shower water issues at a rate corresponding with the extent valve 84 is open, the issuing hot mixed shower water coming from the temperature control 22 at the predetermined shower water temperature.
An alternative water volume supply control unit 62A is shown in Figures 4 and 5 in which the body 64 is of cruciform shape and is mountable on the wall 6 over the bath 10 for the bath spout 68 to discharge the bath water thereinto. In this case the control knobs 74,86 are substantially horizontal. The water inlets 70 and 82 may be of adjustable attitude, for example pivotable or swivelable, to facilitate connection to the water pipes 34,38. (Figure 1).
Another water volume supply control unit 62B is shown in Figures 6 and 7. The water volume supply unit 62B may be built into a wall, say the wall 4 formed with a suitable recess 88. The bath water conduit 66 comprises an outlet 90 connected, by a suitable pipe (not shown) in the wall, to a bath water spout shown for example at 68B in Figure 1 over the bath 10 and built into the wall 4. The shower water outlet nozzle 78 is connected, by a suitable pipe (not shown) in the wall to a variable directional shower head 16B mounted on the wall 4 over the bath 10. The knobs 74 and 84 may be removable and project through a removable cover plate 92 mounted in position on the unit 62B and/or the wall 4 to mask the recess 88.
