ABLUTIONARY SYSTEM
This invention relates to an ablutionary system for washing and, in particular, it
relates to an ablutionary system for showering. It also relates to a kit of parts for
an ablutionary system and methods of assembly and installation. More
especially, the invention relates to mixer valves employed in such installations
and, in particular, but not exclusively, to a modular mixer valve that can be
adapted for use in different systems and/or that can be provided with one or more
accessories that may add to or change functionality of the mixer valve and/or the
system in which the mixer valve is employed.
Ablutionary systems, such as showers, typically comprise a mixer valve that
delivers water to an outlet and then on through a conduit to a shower head. The
mixer valve controls the temperature and/or flow rate of the water delivered to
the outlet. Shower mixer valves may be of exposed type or built in type.
Exposed type mixer valves are mounted to a wall and project therefrom, usually
into the enclosure that surrounds the shower. Built in type mixer valves are
mounted behind the wall and are thus hidden from the view of the user. The
outlets and controls project through the wall but the valve body is behind the
wall. This invention relates to both types of shower valve.
A known exposed type shower system is shown in Figure 31 and comprises a
moveable shower head attached to a flexible hose connected to an outlet on the
underside of the mixer valve body. In another known exposed type shower
system, a large fixed “rain” shower head is attached to a rigid pipe connected to
an outlet on the topside of the mixer valve body. In another known exposed type
shower system, a diverter valve is connected to an outlet on the topside of the
valve body and is operable to deliver water to a moveable shower head or a fixed
shower head.
In such known exposed type shower systems, the outlet is integral with the valve
body and has a connection axis that is orientated vertically when the mixer valve
is installed. In order to accommodate the different systems, two outlet positions
are required – one having the outlet in the underside for use with a moveable
handset and another having the outlet in the topside for use with an overhead
shower or diverter valve. The provision of two valves, one with the outlet in the
topside and another with the outlet in the underside, adds to costs while the
provision of two outlets in the same valve, one in the topside and another in the
underside, requires a blanking plug to close the outlet that is not used which may
detract from the aesthetics of the mixer valve.
A known built-in type shower systems is shown in Figure 32 and comprises a
moveable shower head attached to a flexible hose connected to an outlet on the
underside of an outlet connector mounted on the wall adjacent to a mixer valve.
The mixer valve body is located in the wall behind a face plate and connected by
a short conduit to the outlet connector. As with the exposed type shower systems,
the connection axis is orientated vertically when the outlet connector is installed.
The present invention has been made from a consideration of the foregoing and
seeks to overcome or mitigate the disadvantages of the known shower systems
and mixer valves for use therein.
The present invention seeks to provide a customisable ablutionary system
including a mixer valve that can be configured with a different outlet connection
according to the type of system without changing the mixer valve body. The
present invention further seeks to provide a modular mixer valve for use in such a
customisable ablutionary system. The invention also seeks to provide modular
mixer valves of both the exposed and built-in types. The invention further seeks
to provide a method of assembling and/or configuring a mixer valve for
customising an ablutionary system and a method of installing a mixer valve
and/or ablutionary shower system employing such a modular mixer valve.
Each of the above objects is to be read disjunctively with the object to at least
provide the public with a useful choice.
In an exemplary embodiment, a customizable ablutionary system for washing
comprises a main body part, a water outlet for delivering water for washing and
an accessory connector, the main body part having a water inlet arranged to
receive a supply of water, wherein the accessory connector includes a water
transfer port and the main body part is adapted to provide a supply of water to the
water transfer port of the accessory connector, wherein the system includes at
least two, different accessory parts each having different functionality, and
wherein the accessory connector is adapted to removably receive one of the at
least two, different accessory parts such that the functionality of the ablutionary
system can be customized by connecting the accessory part that has the desired
functionality to the accessory connector.
This is advantageous as the ablutionary system is modular and can easily be
added to and modified by connecting one or more different accessory parts to the
accessory connector. The accessory part is advantageous as it may enhance the
functionality of the ablutionary system, as will be described in more detail below.
The ablutionary system allows the customization of an ablutionary apparatus,
such as a shower, so that it can receive a variety of accessory parts to suit a user’s
needs. Also, the ablutionary system can be installed with one type of accessory
part and can be later modified without needing to replace the whole ablutionary
system.
It may be that the accessory connector is integral with the main body part, in that
it forms part of the main body part, or is connected to the main body part by a
conduit. Thus, depending on whether the ablutionary shower system is an
exposed type or built in type, the accessory connector can be conveniently located
to attach the accessory part.
It may be that the accessory part is removably connectable to the accessory
connector. This is advantageous as it allows the ablutionary system to be
customized with accessory parts that may or may not require or need to interact
with the water moving through the ablutionary system when it is in use.
The accessory part may be arranged to receive or utilise a flow of water in use
from the water transfer port of the accessory connector. In this case, the
accessory part is a “wet” accessory part. Alternatively, the accessory part may be
arranged not to receive or utilise a flow of water in use from the water transfer
port of the accessory connector. In this case, the accessory part is a “dry”
accessory part.
It may be that the accessory part includes the water outlet or provides a flow path
to the water outlet. This is advantageous as the accessory part forms a manifold
for directing water to the water outlet allowing the method of delivery of the
water to be customised. Accordingly, the water outlet may be arranged to
connect to a variety of water delivery devices that deliver water for washing.
Thus, the delivery device may be a flexible shower hose for a handset or a rigid
pipe for a fixed shower head or a body jet bar or a wash down hose for cleaning
the shower or a bath filling spout module or combinations thereof. Thus, the
water outlet provides means for water to leave the ablutionary system, possibly
via a delivery device removably connected thereto, for use by a user of the
system. The water outlet may include a connection means, such as a screw
thread, to attach the delivery device conduit for delivering water to a shower
head.
It may be that the main body part includes the water outlet and the accessory part
may receive or utilise a flow of water in use from the water transfer port of the
accessory connector. For example, the accessory connector may provide a
second, separate water outlet or a flow path to a second, separate outlet. This is
advantageous as the number and arrangement of water outlets for delivery of the
water to be customised. Accordingly, one or more water outlets may be arranged
to connect to a variety of water delivery devices that deliver water for washing.
Thus, the delivery device may be a flexible shower hose for a handset or a rigid
pipe for a fixed shower head or a body jet bar or a wash down hose for cleaning
the shower or a bath filling spout module or combinations thereof.
It may be that the main body part includes the water outlet and the accessory part
does not receive or utilise a flow of water in use from the water transfer port of
the accessory connector. This is advantageous as the accessory part can provide
functionality that does not rely on water flow and different accessory parts can be
fitted to suit the required functionality.
“Dry” accessory parts may include means to provide any of the following;
parking socket for shower handset, a soap dish, a storage shelf, a soap/lotion
dispenser, a cup holder, a clamp for shampoo/soap/lotion etc, a hook for attaching
articles, a clock, a radio or other music player, a USB slot to connect a MP3 or
other music player, a Wi-Fi or other wireless receiver such as a Bluetooth speaker
for receiving information to relay to a user of the shower such as streaming news,
music, weather updates or a schedule, mood lighting, a note pad, a picture display
frame that may be a digital photograph frame or a shaving mirror. It will be
appreciated that the invention is not limited to these specific examples of “dry”
accessory parts.
“Wet” accessory parts may include means to provide any of the following; a
water outlet, a temperature display of the water, a flow rate meter to measure the
flow rate of the water, a soap injector to introduce soap into the water flow, an
aromatherapy oil injector to introduce aromatherapy oils into the water flow, an
air injector to introduce air into the water flow, an on/off valve actuated by a
push button, a shower energy usage calculator that measures properties of the
water flow to calculate the energy usage, a shower cost meter that measures
properties of the water flow to calculate the cost of showering, or an anti-mist
shaving mirror which flows the water past the mirror to maintain the mirror mist
free. It will be appreciated that the invention is not limited to these specific
examples of “wet” accessory parts.
It may be that the accessory connector is arranged to engage with a
complimentary connecting part on the accessory part to secure the accessory part
to the accessory connector, the arrangement forming a connector system. Further,
the connector system may also include a release element arranged to allow
separation of the accessory part from the accessory connector when the release
element is actuated. This is advantageous as the accessory part will be securely
retained on the accessory connector until actuation of the release element.
It may be that the accessory connector comprises (a) a bayonet connector; or (b) a
snap fit connector; or (c) a screw thread connector; or (d) a grub screw arranged
to engage in a complimentary recess type connector. It will be appreciated that
the connector system is not limited to these particular options and may comprise
any appropriate connector system that provides a reliable connection between the
parts with suitable seal integrity and releasability as may be necessary.
The accessory part may include a further accessory connector to receive a further
accessory part. The further accessory connector may include a further water
transfer port. Several accessory parts may be connected together in series.
Where more than one accessory part is provided, these may be “dry” accessory
parts or “wet” accessory parts or a combination of “wet” and “dry” accessory
parts. This is advantageous as the accessory parts can be connected to add
additional functionality to the ablutionary system. Thus, several accessory parts
can be added to provide a variety of functions or water outlet arrangements.
It may be that the ablutionary system includes a removable water transfer port cap
to sealingly close the water transfer port or further water transfer port, if present,
when the port is not in use. The cap can be removed at a later time if further
functionality is required with the addition of further accessory parts.
It may be that the water inlet comprises a supply of relatively hot water and a
supply of relatively cold water, the main body part including a valve to control
the temperature of the water at the water outlet by mixing the hot and cold water
supplies. The valve may be controlled by mixing controls which are provided on
the main body part. The valve may be a thermostatic valve.
It may be that the ablutionary system includes flow rate controls for controlling
the rate of flow of water to the water outlet when in use. The flow rate controls
may be provided on the main body part.
It may be that the connector system that connects two parts to be coupled, i.e. the
accessory part and main valve body part or the accessory part and further
accessory part where more than one accessory part is provided, is a snap fit
connector system. This provides an easy and secure connection. The snap fit
connector system may comprise a first locking element adapted to be secured to
one of the parts and a second locking element, complimentary to the first locking
element, adapted to be secured to the other part to be coupled, the second locking
element arranged to engage behind at least a portion of the first locking element
to secure the two elements together. The second locking element may include
engagement lugs adapted to engage with the part that the first locking element is
secured to prior to engaging with the first locking element. The first locking
element may be arranged to flex or rotate within the part it is secured in order to
allow the second locking element to engage behind at least a portion of it. The
first locking element may comprise a locking ring having resilient flanges that
engage with one of the parts, the resilient flanges arranged such that the locking
ring can rotate relative to the part in which it is secured, and the second locking
element comprises an activator ring having axially extending engagement lugs
adapted to engage with the part that the locking ring is secured to prior to
engaging with the locking ring, the activator ring adapted such that engagement
of the locking ring and activator ring in an axial direction urges the locking ring
to rotate against the force of the resilient flanges and then resile back to its
original position locking the activator ring behind the locking ring.
In an exemplary embodiment, a kit of parts may be provided for forming the
ablutionary system of the type described herein.
This is advantageous as the kit can comprise one or more accessory parts so that a
user can customize their ablutionary shower system. The system can be
customised to receive a variety of accessory parts to suit a user’s needs. Also,
the ablutionary system can be installed with one type of accessory part and can be
later modified without needing to replace the whole system. For example, the
accessory part may comprise a manifold to direct water to a delivery device for
use that is adapted to connect to the accessory part. For example, the accessory
part may connect to a delivery device comprising a hose and movable shower
head. Alternatively, the accessory part may connect to a delivery device
comprising a fixed pipe and rigid shower head. Alternatively, the accessory part
may connect to both a delivery device comprising a hose and movable shower
head and a delivery device comprising a fixed pipe and rigid shower head with a
diverter for directing water flow to either one or both of the delivery devices.
These alternative configurations can be interchanged easily. Other configurations
of single or multiple delivery devices may be employed.
It may be that the kit includes at least one further accessory part arranged to
connect to the connector of the main body part or a further connector on the
accessory part.
In an exemplary embodiment, an accessory part may be provided for enhancing
the functionality of a customizable ablutionary system, such as a shower, the
accessory part including part of a connector system to removably connect the
accessory part to an accessory connector of a customizable ablutionary system,
the accessory part including a water receiving aperture as part of the connector
system to receive a supply of water from the ablutionary system when in use.
This is advantageous as the shower accessory part can have a multitude of
configurations and can be used to configure the ablutionary shower system.
It may be that the accessory part includes a water receiving aperture which is
arranged to receive a flow of water from the ablutionary system when in use.
It may be that the accessory part includes a water outlet for delivering water for
showering. The water outlet, separate from the water receiving port, provides
means to connect a delivery device such as a shower hose or a fixed pipe with
fixed shower head or a body jet bar or a wash down hose for cleaning the shower
or a bath filling spout module or combinations thereof. Thus, the water outlet
provides means for water to leave the ablutionary system, possibly via a delivery
device removably connected thereto, for use by a user of the system. Preferably
the water outlet includes a connection means, such as a screw thread, to attach the
delivery device conduit for delivering water to a shower head.
It may be that the accessory part includes a water transfer port arranged to receive
a supply of water from the ablutionary system through the water receiving port
for supplying a further accessory part connected to the water transfer port. This
is advantageous because the accessory part can be connected in series with a
further accessory part. Preferably, the accessory part includes a removable
transfer port cap, to sealingly close the water transfer port when not in use.
In another embodiment, an ablutionary system for washing may include a main
body part having a water inlet arranged to receive a supply of water, the
ablutionary system further comprising a water outlet for delivering water for
washing and an accessory connector adapted to receive an accessory part.
This is advantageous as the accessory part can enhance the functionality of the
ablutionary system. The accessory part may include any of the accessory parts
described herein.
In another embodiment, an accessory part for enhancing the functionality of an
ablutionary system, such as a shower, may include part of a connector system to
removably connect the accessory part to a connector of an ablutionary system.
In another embodiment, a modular mixer valve may include a detachable
accessory part. The accessory part can enhance the functionality of the mixer
valve. The accessory part may include any of the accessory parts described
herein. The modular mixer valve may provide outlet water for a water supply
system for hand washing, bathing, showering. Thus the outlet may be connected
to a delivery device such as a shower hose or a fixed pipe with fixed shower head
or a body jet bar or a wash down hose for cleaning the shower or a bath filling
spout module or combinations thereof.
In another embodiment, a modular mixer valve may include hot and cold water
inlets for connection to supplies of hot and cold water, valve means for
controlling mixing of hot and cold water according to user selection of outlet
water temperature, an accessory part connectable to a water transfer port, and a
water outlet separate from the water transfer port, wherein the accessory part is

flow of water from the main body part. The outlet may be provided by the main
body part, the accessory part connected to the main body part or by the further
accessory part or combinations thereof. In other embodiments, such further
accessory part may not be in fluid communication with the accessory part
connected to the valve body. In this way, the accessory part connected to the
main body part may receive or utilise a flow of water from the main body part.
The outlet may be provided by the main body part or the accessory part connected
to the main body part or combinations thereof. The selection and assembly of
different combinations of accessory parts may further add to functionality of the
mixer valve. In general the number of accessory parts that can be connected in
series may be limited by practical and/or the aesthetic considerations.
The mixer valve may be of the exposed type having a valve body that is exposed
(visible) in use, for example mounted on a wall or similar support surface, with
the transfer port in the valve body. The outlet may be provided in the valve body
or in the accessory part connected to the transfer port. Alternatively, two outlets
may be provided. A diverter may be employed to select either one or both
outlets. One outlet may be provided in the valve body and another outlet in the

part may be in fluid communication with the accessory part connected to the main
body part. In this way, both accessory parts receive water from the main body
part and the outlet may be provided by the accessory part connected to the main
body part or by the further accessory part. In other embodiments, such further
accessory part may not be in fluid communication with the accessory part
connected to the valve body. In this way, only the accessory part connected to
the main body part receives water from the main body part and the outlet is
provided by that accessory part. The selection and assembly of different
combinations of accessory parts may further add to functionality of the mixer
valve. In general the number of accessory parts that can be connected in series
may be limited by practical and/or the aesthetic considerations.
The mixer valve may be of the exposed type in which the main body part is
exposed in use, for example mounted on a wall or similar support surface.
Alternatively, the mixer valve may be of the built-in type where the main body
part is concealed in use, for example by a cover plate and may be at least partially
recessed in a wall or similar support surface. In both types of the valve, the
outlet may be configured for connection to a delivery device selected from a
flexible hose, a rigid pipe or a combination of a flexible hose and a rigid pipe by
selection of an accessory part having an appropriate outlet or combination of
outlets and assembling a main body part of the valve with the accessory part
connected to the main body part directly or indirectly via a further accessory part.
In an exemplary embodiment, a modular shower system may employ a mixer
valve having a control module and an accessory module selected from a plurality
of accessory modules. The control module may include a valve body with inlets
for connection to supplies of hot and cold water and a mixing valve for
controlling mixing of the hot and cold water according to user selection of outlet
water temperature. The control module may have an outlet for connection to a
water delivery device that delivers water to a shower as previously described.
Alternatively or additionally, the accessory module may include an outlet for
connection to a water delivery device that delivers water to a shower as
previously described. A required shower system can be configured by selecting
and assembling the appropriate control module and accessory module so that the
delivery device receives water from the control module directly and/or via the
accessory module. At least one further accessory module may be provided in
addition to the selected control module and accessory module for further adapting
and customising the shower system to the user’s requirements. Some accessory
modules may connect to the water path from the control module. Other accessory
modules may be isolated from the water path. The control module may be
selected from a plurality of control modules. Different combinations of control
modules and accessory modules may be employed allowing shower systems to be
configured with different functionality.
In an exemplary embodiment, a method of assembling a mixer valve for a shower
system may include selecting a control module including a main body part
housing a mixing valve and having inlets for connection to supplies of hot and
cold water and a water transfer port for water received from the mixing valve,
selecting a detachable accessory module connectable to the water transfer port
directly or indirectly wherein one of the control module and accessory module
has an outlet for connection to a delivery device selected from a flexible hose, a
rigid pipe and combinations thereof, and providing a fluid connection between
the mixing valve and the outlet. The detachable accessory module may include
the outlet.
The method may allow a single control module to be provided for use with any
selected one of a plurality of different outlet accessory modules whereby the
mixer valve may be configured for different shower systems by selecting the
appropriate outlet accessory module and connecting the water receiving port of
the selected outlet module to the water transfer port of the control module
directly or indirectly. Where the selected outlet accessory module is connected to
the water transfer port directly, the water receiving port of the selected outlet
accessory module may co-operate with the water transfer port of the control
module to provide a fluid connection between the control module and the outlet
accessory module. Where the selected outlet accessory module is connected to
the water transfer port indirectly, an accessory part may be disposed between the
control module and the outlet accessory module having a water receiving port that
co-operates with the water transfer port of the main body part and a water transfer
port that co-operates with a water receiving port of the outlet module. More than
one accessory part may be disposed between the control module and the outlet
accessory module. Where provided, the or each accessory part provided between
the control module and the outlet accessory module may comprise a module for
monitoring a characteristic of the outlet water flow from the control module, for
example the water flow rate or water pressure or water temperature or
combinations thereof and optionally displaying a value of the monitored
characteristic(s). Alternatively, the or each accessory part provided between the
control module and the outlet accessory module may comprise a module for
modifying the outlet water flow from the control module, for example by
introducing an additive to the water such as soap, an aromatherapy oil, perfume
or fragrance or any other suitable additive.
The outlet accessory module may be configured to attach an accessory part. For
example, the outlet accessory module may have a formation such as a socket
isolated from the water flow for mounting an accessory part that does not require
connection to the water flow to perform its function, i.e. a “dry” accessory part.
Thus the outlet accessory module may support an accessory part including but not
limited to a parking socket for shower handset, a soap dish, a storage shelf, a
soap/lotion dispenser, a cup holder, a clamp for shampoo/soap/lotion etc, a hook
for attaching articles, a clock, a radio or other music player, a USB slot to
connect a MP3 or other music player, a Wi-Fi or other wireless receiver such as a
Bluetooth speaker for receiving information to relay to a user of the shower such
as streaming news, music, weather updates or a schedule, mood lighting, a note
pad, a picture display frame that may be a digital photograph frame or a shaving
mirror. Alternatively, the outlet accessory module may have a water transfer port
for connection to a water receiving port of an accessory part connected to the
outlet module that receives or utilises a flow of water to perform its function, i.e.
a “wet” accessory part. Thus the outlet accessory module may connect to an
accessory part including but not limited to a temperature display of the water, a
flow rate meter to measure the flow rate of the water, a soap injector to introduce
soap into the water flow, an aromatherapy oil injector to introduce aromatherapy
oils into the water flow, an air injector to introduce air into the water flow, an
on/off valve actuated by a push button, a shower energy usage calculator that
measures properties of the water flow to calculate the energy usage, a shower cost
meter that measures properties of the water flow to calculate the cost of
showering, or an anti-mist shaving mirror which flows the water past the mirror
to maintain the mirror mist free. Where the outlet accessory module has a water
transfer port, an accessory device that does not require connection to the water
flow to perform its function may be connected to the outlet accessory module so
that the water transfer port is closed by the accessory part or remains closed if the
transfer port is self-closing.
The interchangeability of different accessory modules and the options for
assembly with different accessory parts connected to or isolated from the water
flow allows a wide range of shower systems to be configured using common
parts. Also a shower system can be reconfigured by changing the accessory
module and/or can have the functionality altered by adding or removing or
changing accessory parts. In this way, the end user can customise the design and
configuration of the shower system and can later change the design and
configuration of the shower system without having to replace the mixing valve
which may represent the major cost of any installation.

A first embodiment of a modular mixer valve 1 is shown in Figures 1 to 4 and an
ablutionary system, comprising a shower system, employing the modular mixer
valve 1 is shown in Figure 5. This first embodiment shows an exposed type
mixer valve 1. Further embodiments showing a built in type mixer valve are
described later.
With reference to Figures 1 to 4, the mixer valve 1 comprises a main body part 2
or control module. The main body part 2 has separate hot and cold inlets (not
shown) for connection to a cold water supply and a hot water supply. In this
embodiment, a rear face 3 of the main body part 2 is mounted in use on a wall or
similar support surface and the inlets are arranged for concealed connection to
supply pipes routed through the wall into the back of the main body part 2. Other
arrangements of the inlets may be employed, as is known in the art.
The main body part 2 houses a mixing valve (not visible) that is arranged to
control mixing of the two supplies to provide a desired outgoing water
temperature and water flow rate. The main body part 2 includes a temperature
control 5 and a flow rate control 6 for user selection of outlet water temperature
and flow rate. In all of the embodiments disclosed herein, the controls 5, 6 may
be replaced with a single sequential control that adjusts both flow rate and
temperature, as will be known to those skilled in the art. The mixing valve may
be a thermostatic valve or a non-thermostatic valve, as is known in the art.
The main body part 2 of the mixer valve has an accessory connector 7 and a
removable accessory part 8 or outlet module is provided that connects to the
connector 7. Figures 1 and 2 show the main body part 2 with the accessory part 8
connected, and Figures 3 and 4 show the main body part 2 with the accessory
part 8 removed. In use, the mixer valve 1 is preferably installed on the wall or
similar support surface with a connection axis of the connector 7 orientated
horizontally or substantially horizontally with the temperature control 5 and flow
rate control 6 on one side and the accessory connector 7 on the opposite side of
the main body part 2.
The accessory connector 7 includes a water transfer port 10, which receives a
supply of water through the main body part 2. The water transfer port 10
comprises a closable aperture and is used to supply the accessory part 8, when
connected to the connector 7, with a supply of water. The water transfer port 10
is associated with the connector 7 and includes a seal between the transfer port 10
and the accessory part 8 for reliable transfer of water between the parts 2, 8.
The accessory part 8 includes a water outlet 4. The water outlet 4 includes a
spigot 9 which carries a screw thread for connecting a delivery device, such as a
flexible hose having a shower head attached thereto. In use, the water outlet 4 is
arranged on the underside of the mixer valve 1 and has a connection axis
orientated vertically or substantially vertically.
In the shower system employing the mixer valve 1 shown in Figure 5, the water
outlet 4 of the accessory part 8 is connected to one end of a flexible hose 70 and a
handset 72 is attached to the other end of the hose 70. The handset 72 is mounted
in a parking socket 71 of a slide rail assembly 73 mounted on the wall. In known
manner, the parking socket 71 is mounted on a slide rail 74 and is vertically
adjustable along the slide rail 74 to adjust the height of the handset 72. The
handset can be removed from the parking socket 71 for manually directing the
spray if desired.
A second embodiment of a modular mixer valve 1 is shown in Figures 6 and 7 and
an ablutionary system, comprising a shower system, employing the modular mixer
valve 1 is shown in Figure 8. This second embodiment employs the same main
body part 2 or control module as the first embodiment and a different removable
accessory part 8 or outlet module. In this embodiment, the accessory part 8 has a
water outlet 4 provided with a threaded spigot 9 as in the first embodiment and an
integrated slide rail 74 of a slide rail assembly 73.
In the shower system employing the mixer valve 1 shown in Figure 8, the water
outlet 4 of the accessory part 8 is connected to one end of a flexible hose 70 and a
handset 72 is attached to the other end of the hose 70. The handset 72 is mounted
in a parking socket 71 that is vertically adjustable along the integrated slide rail
74 to adjust the height of the handset 72. The handset 72 can be removed from
the parking socket 71 for manually directing the spray if desired.
A third embodiment of a modular mixer valve 1 is shown in Figures 9 and 10 and
an ablutionary system, comprising a shower system, employing the modular mixer
valve 1 is shown in Figure 11. This third embodiment employs the same main
body part 2 or control module as the first and second embodiments and a different
removable accessory part 8 or outlet module. In this embodiment, the accessory
part 8 has a first water outlet 4 provided with a threaded spigot 9 as in the first
embodiment and a second water outlet 4’. The accessory part 8 also includes a
diverter valve member (not visible) and a diverter valve member control 11. The
diverter valve member switches the outlet path within the accessory part 8
between water outlet 4 and water outlet 4’. Thus, water received from the water
transfer port 10 is diverted to either outlet 4 or 4’ according to the position of the
diverter valve member. It will be appreciated that the diverter valve member may
be such that both water outlets 4, 4’ can be supplied with water simultaneously.
In the shower system shown in Figure 11, the first water outlet 4 is arranged on
the underside of the mixer valve 1 and the second outlet 4’ is arranged on the
topside of the mixer valve assembly so that both outlets 4, 4’ are orientated
vertically or substantially vertically. The outlet 4 of the accessory part 8 is
connected to one end of a flexible hose 70 and a handset 72 is attached to the
other end of the hose 70. The outlet 4’ is connected to one end of a rigid water
supply pipe assembly 75 and a fixed over head shower 76 is attached to the other
end of the water supply pipe assembly 75. A vertical portion 74 of the water
supply pipe assembly 75 doubles as a slide rail for a parking socket 71 for the
handset 72 that is vertically adjustable along the slide rail 74 to adjust the height
of the handset 72. The handset 72 can be removed from the parking socket 71 for
manually directing the spray if desired. In a modification (not shown) a separate
slide rail assembly may be provided mounted on the wall or similar support
surface as shown in Figure 5
As will be apparent from the description of the embodiments of Figures 1 to 11, a
modular mixer valve 1 is provided having a main body part 2 or control module
for connection to supplies of hot and cold water. The main body part 2 houses a
mixing valve for user selection of outlet water temperature and flow rate. The
main body part 2 can be configured for installation in different shower systems by
selectively connecting different accessory parts 8 or outlet modules to the
accessory connector 7 of the main body part 2 for orientating one or more outlets
separate from the water transfer port 10 for connection to a water delivery
conduit supplying water to a shower spray head. The different accessory parts 8
thus provide interchangeable rigid outlet modules or manifolds that can be easily
detached and replaced to allow the mixer valve 1 to be customized using the same
main body part 2 or control module. This modular design of the mixer valve 1
allows the shower system to be customized and easily tailored to a user’s
requirements.
Referring now to Figure 12, a cross-section through the accessory part 8 of the
first embodiment is shown connected to the main body part 2 of the mixer valve 1
(only a portion of which is shown for clarity wherein the dashed lines show where
the main body continues).
The accessory part 8 includes a chamber 16 and a water receiving port including a
hollow port engaging member 13 in communication with the chamber 16. The
port engaging member 13 is adapted to be received within the water transfer
port 10 of the main body part 2. Accordingly, the transfer port 10 includes a
tubular collar 14 within which the port engaging member 13 is received. It will
be appreciated that the collar 14 could be any suitable shape such as elliptical or
square as non-limiting examples.
The transfer port 10 is surrounded by a shroud 19, which comprises a portion of
the main body part 2 that extends distal to the port 10. The port engaging
member 13 includes a groove 15 that carries a sealing element such as an O-ring
(not shown), which seals against the tubular collar 14. Thus, water is able to flow
from the main body part 2, through the collar 14 and port engaging member 13
into the chamber 16 of the accessory part 8.
The chamber 16 is also in communication with the water outlet 4 and in this
embodiment allows water to flow freely through the chamber 16 to the outlet 4.
In this way, outlet water from the mixing valve flows to the outlet 4 through a
waterway that includes the accessory part 8. The accessory part 8 is thus a “wet”
accessory part in that it receives a flow of water from the main body part 2. It
will be appreciated that any of the interchangeable accessory parts 8 of the
embodiments of Figures 1 to 11 may be mounted on the main body part 2 in
similar manner.
The accessory part 8 also includes an end cap 18 that is removable to reveal a
socket 24 in the end of the accessory part 8 that is isolated from the flow of water
through the accessory part 8. The socket 24 is configured for mounting a further
accessory part (not shown) for increasing the functionality of the shower system.
The further accessory part is thus a “dry” accessory part in that it does not
receive a flow water from the main body part 2.
Figure 13 shows the “wet” accessory part 8 of the first embodiment with a further
“dry” accessory part 8’ mounted thereon. The further accessory part 8’includes a
base part 61 that seats in the socket 24 and a ring shaped holder 60 for mounting
a removable soap dish (not shown). The base part 61 may be releasably secured
by any suitable means, for example a grub screw mounted in wall of the socket 24
to engage a groove extending around the perimeter of the base part 61. The
holder 60 may be of oval-shape or any other shape and may be configured to
support other articles.
Figure 14a shows a “dry” accessory part 8’ including a cup holder 62 and cup 63
and Figure 14b shows “a dry” accessory part including a bottle holder 64 and
pump operated soap bottle 65. Other examples of “dry” accessories that may be
employed with the accessory part 8 of the first embodiment will be apparent to
those skilled in the art. The accessory part of the second and third embodiments
may likewise be provided with a removable end cap for mounting a “dry”
accessory part 8’.
Referring now to Figure 15, there is shown a modification to the accessory part 8
of the first embodiment to include a further accessory connector 49 and a further
water transfer port 17. The accessory part 8 includes a shroud 29 that comprises
an annular flange that surrounds the further water transfer port 17. In Figure 15,
the further water transfer port 17 is closed by a removable end cap 18.
The cap 18 includes a tubular plug 20 that plugs the further water transfer port 17
and an end cover 21. The plug 20 extends from the end cover 21 and includes a
groove 22 that carries an annular seal such as an O-ring (not shown) to seal
between the plug 20 and the further water transfer port 17. The end cover 21 is
sized and arranged to close the end of the accessory part 8 and meet with an
external surface 23 of the shroud 29. The plug 20 closes the further water
transfer port 17. Alternatively, the further transfer port may be self closing.
In use, the end cap 18 may be removed and a further “wet” accessory part
connected to the accessory part 8. Thus, the further “wet” accessory part may
have a port engaging member including a water receiving port adapted to be
received in the further water transfer port 17 of the accessory part 8 and sealed by
a seal such as an O-ring (not shown) in similar manner to the seal between the
plug 20 and the water transfer port 17. Alternatively, a “dry” accessory part may
be connected to the accessory part 8. Thus, the “dry” accessory part closes the
water transfer port 17 of the accessory part 8. The accessory parts of the second
and third embodiments may likewise be provided with a removable end cap and
transfer port for mounting a “wet” accessory part 8” or a “dry” accessory part.
Figures 16a, 16b, 16c and 16d show examples of “wet” accessory parts 8” that
can be used with the accessory part 8 of the first embodiment. Figure 16a shows
an accessory part 8” having a temperature sensor (not shown) and a temperature
display 66 to provide a read-out of the water temperature. The temperature
sensor may extend into a chamber 16 within the part 8 to measure the temperature
of the water flowing therethrough. Alternatively, the temperature sensor may be
located on a wall section of the waterway and measure the temperature of the
water flowing therethrough, for example by conduction of heat through the wall
section. Figure 16b shows an accessory part 8” having a clock and/or timer 67.
The clock may operate independently of the water flow and the timer may start
and stop timing on detection of a change in the flow through the accessory part 8.
Figure 16c shows an accessory part 8” having an on/off switch 68 or valve that
controls flow to the water outlet 4. Figure 16d shows an accessory part 8” having
a soap/oil infusing device 69. The soap/oil infusing device 69 is arranged to
introduce soap/oil into the water flowing into the accessory part 8 and out
through the water outlet 4. The accessory parts shown in Figures 16a to 16d are
“wet” accessory parts in that they utilise the flow of water to the outlet 4 to
provide additional functionality. Other examples of “wet” accessory parts that
may be employed with the accessory part 8 of the first embodiment will be
apparent to those skilled in the art. The accessory parts of the second and third
embodiments may likewise be provided with a removable end cap and transfer
port for mounting a “wet” accessory part 8”. In other embodiments, the accessory
part 8 may include any of the accessory parts 8” in a single accessory part.
In the embodiments described thus far, the accessory part 8 comprising the water
outlet module with one or more outlets is mounted directly on the main body
part 2 of the mixer valve 1 and one or more further “wet” or “dry” accessory parts
may be mounted on the accessory part 8. However, this is not essential and an
arrangement having a further “wet” accessory part 8” connected between the main
body part 2 and the accessory part 8 or outlet module is shown in Figures 17 and
The further “wet” accessory part 8” includes a water receiving port having a port
engaging member 13” to engage with the water transfer port 10 of the main body
part 2. The further accessory part 8” also includes a water transfer port 17”,
which is in fluid communication with the port engaging member 13” via the
chamber 16”. In this embodiment, the further accessory part 8” includes a
temperature sensing element (not shown) and a temperature display 100. The
temperature sensing element is arranged to measure the temperature of the water
flowing in the chamber 16” and present the temperature to a user on the
temperature display 100 located on the external surface. The outlet module is of
a similar general construction to the accessory part 8 of the first embodiment and
the port engaging member 13 engages with the water transfer port 17” of the
further accessory part 8” and the water outlet 4 is connectable to a delivery
device such as a flexible hose as described previously. The outlet module may
comprise any of the other outlet modules described herein. The accessory parts 8,
8” are connected in series and more than one “wet” accessory part may be
connected between the main body part 2 and the accessory part 8 comprising the
outlet module. Alternatively or additionally one or more “wet” or “dry”
accessory parts may be connected after the accessory part 8 comprising the outlet
module. In a modification (not shown), a further “wet” accessory part 8” may
include a further water outlet for connection to a further delivery device such as
previously described herein. All possible combinations of wet and dry accessory
parts are envisaged and are within the scope of the invention.
Referring now to Figure 19, a modification of the first embodiment is shown in
which the accessory part 8 includes a temperature sensor and temperature display
100 for displaying the outlet water temperature. The temperature sensor may be
replaced by any other device that utilises a fluid flow to perform its function such
as those described herein. The outlet module may comprise any of the other outlet
modules described herein.
Referring now to Figure 20, another modification of the first embodiment, is
shown in which the main body part 2 has an outlet 4 on the underside for
connection to a fluid delivery device such as a flexible hose for a shower handset
and the accessory part 8 connected to the main body part 2 does not have an
outlet. In a modification, the outlet may be on the topside of the min body part
for connection to a rigid pipe supplying an overhead shower. The accessory part 8
may be a “wet” accessory part or a “dry” accessory part as described herein. In
Figure 20, the accessory part 8 is a “wet” accessory part including a temperature
sensor (not shown) that utilises a flow of water for monitoring outlet water
temperature and providing an indication of the temperature via a temperature
display 100. Any other accessory part that receives or utilises a flow of water for
its function may be employed. This embodiment may employ more than one
accessory part as described herein.
In a modification (not shown) of Figure 20, the accessory part 8 may have an
outlet in addition to the outlet on the main valve body. The outlets may be
connected to any of the water delivery devices such as those described herein.
The accessory part may have a control for preventing/allowing water flow to the
accessory outlet in addition to water flow to the outlet on the main body part 2.
Referring now to Figures 21a, 21b and 21c, further embodiments of a different
modular mixer valve 1 of the exposed type including a bar mixer valve and
ablutionary systems employing such valve are shown.
The bar mixer valve shown in Figures 21a, 21b and 21c has a tubular, generally

combination. In this embodiment, a further water transfer port of the first “wet”
accessory 8 is closed by a further “dry” accessory part 8’ connected to the further
accessory connector of the outlet module. The further accessory part 8’
comprises a holder for a soap dish but may comprise any other “dry” accessory
part such as those described herein.
The shower installations described to date employ modular mixer valves of the
exposed type. Figures 22a, 22b, 22c and 22d show various configurations of
ablutionary shower systems employing modular mixer valves 1 of the built-in
type.
Figure 22a shows a system where the main body part (not shown) is recessed in a
wall and concealed by a wall mounted panel or plate 80. Concentric
temperature/flow controls 5, 6 are provided on the wall mounted panel 80 for
controlling the temperature and/or flow rate of the outlet water. The panel 80
also includes an accessory connector that has an accessory part 8 comprising an
outlet module with a water outlet 4 connected to it. The main body part or
control module, which contains the mixing valve for the shower, may, in this
example, be integral with the panel 80 and the accessory connector receives outlet
water from the mixing valve. The accessory part 8 or outlet module may be
substantially similar to the accessory part shown in Figures 6 to 8 with the
outlet 4 connected to a handset 72 via a flexible hose 70 and with an integrated
slide rail 74 for mounting a parking socket 71 for the handset 72.
Figure 22b shows a system in which coaxial temperature/flow controls 5, 6 are
provided on a first wall mounted panel or plate 81 for controlling the temperature
and/or flow rate of the outlet water. The main body part or control module of the
mixer valve (not visible) may be integral with the panel 81 and contain a mixing

It will be appreciated that the arrangements of the accessory part 8 shown in
Figures 22b, 22c and 22d could be provided with the single panel or plate 80 as
shown in Figure 22a. The arrangement of the main body part (not visible) in
Figures 22c and 22d may be the same as that described for Figure 22b. The
concentric controls 5, 6 in Figures 22a, 22b, 22c and 22d may be replaced by
controls arranged separately from each other, for example side by side or any
other suitable configuration.
Figure 23 shows the accessory part 8 of Figure 22b with the sealing cap 18
removed to reveal a further accessory connector 49. A further water transfer
port 17 is also provided to supply water to a further “wet” accessory part 8” if
required. Alternatively, a “dry” accessory part 8’ may be provided that closes the
further water transfer port 17. Alternatively the accessory part 8 may be of the
type shown in Figures 12 and 13 for mounting a “dry” accessory part only. All
configurations of “wet” and “dry” accessory parts as described herein may be
employed.
Figure 23 also shows a variety of further “dry” and “wet” accessory parts 8’, 8”
that may be connected to the further accessory connector 49. The “dry”
accessory parts 8’ include a hook 90 for attaching an article such as a sponge, and
a holder 91 for supporting a soap dish 92 or a soap dispenser 93 or any other
article such as a cup (not shown). The “wet” accessory part 8” may include a
temperature sensor and a temperature display 100. A second water outlet 4’ may
also be provided giving the user more options for configuring the shower system.
Such “wet” accessory parts 8” may include a still further accessory connector 49’
so a still further “wet” or “dry” accessory part 8 can be connected. All
configurations and combinations of wet and dry accessory parts such as described
herein may be employed with the built-in mixer valves.
In each of the preceding embodiments, accessory parts 8, 8’ and 8” may be
connected to each other or to the accessory connector 7 of the main body part 2
by a connector system 30. An embodiment of a connector system 30 is shown in
Figures 24 to 30, although references to a connector system are not limited to the
specific arrangement shown in Figures 24 to 30.
The connector system 30 includes two main parts; a locking ring 31 and an
activator ring 32 shown in Figure 24. The locking ring 31 is arranged to be
mounted within the shroud 19, 29 that surrounds the water transfer port 10 or
further water transfer port 17 of the main body part 7 or accessory part 8. The
activator ring 32 is arranged to be mounted to the port engaging member 13 of the
accessory part 8.
The locking ring 31 comprises a ring body that includes a plurality of mounting
clips 33 circumferentially spaced around its outer surface. The mounting clips 33
extend from one axial side of the locking ring are hinged therefrom by hinges 34.
The hinges 34 are resilient and are adapted such that a free end of each mounting
clip stands radially outward of the ring body and can be compressed radially
inwardly against the force of the hinges 34. The locking ring 31 also includes a
plurality of resilient flanges 35 or tabs that extend radially outwardly and are
oriented in an axial direction. The resilient flanges are thus arranged to flex in a
circumferential direction. The inwardly facing surface of the ring body includes
a plurality of circumferentially spaced locking ramps 36. The locking ramps 36
comprise wedge shaped projections and each includes a bearing surface 37 that is
inclined to the axial direction. The locking ramps 36 also include a stepped
retaining surface 38.
Figure 25 shows the locking ring 31 about to be mounted within the shroud 19,
29. The shroud 19, 29 comprises an annular flange having a radially inwardly
extending lip 40 that projects from its free end. The shroud 19, 29 also includes a
plurality of axially extending grooves 41 formed in its inwardly facing surface.
The grooves 41 extend through the lip 40 at the free end and are complimentary
to the resilient flanges 35. Two diametrically opposed apertures 39 are provided
either side of the water transfer port 10, 17, the purpose of which will be
described below. When the locking ring 31 is mounted into the shroud 19, 29, the
resilient flanges 35 are aligned with the grooves 41 and the mounting clips 33 are
arranged to be compressed about their hinges 34 as they pass within the lip 40.
Once the locking ring 31 clears the lip 40 and sits in its mounted position within
the shroud, the mounting clips 33 resile radially outwardly to engage behind the
lip 40 thereby securing the locking ring within the shroud with the resilient
flanges 35 in the grooves 41. The mounting clips 33 are arranged to prevent the
locking ring moving axially within the shroud, but allow rotational movement,
which is resisted by the resilient flanges 35.
Figure 26 shows the activator ring 32 mounted on the accessory part 8. The
activator ring 32 comprises a ring body 43 having a plurality of circumferentially
spaced rotation teeth 44 that extend radially outwardly. The ring body 43 also
includes two axially extending lugs 45 that are located on the same side of the
ring body but are located in diametrically opposed positions. The lugs 45 are
complimentary to the apertures 39. The activator ring 32 is secured to the port
engaging member 13 by adhesive (although it may be a friction fit, a circlip or a
releasable connection).
Figure 27 shows the accessory part 8 with the activator ring 32 mounted thereon
partially engaged with the accessory connector 7 of the main body part 2 (or
another accessory part 8) with its associated locking ring 31 mounted with the
shroud 19. The lugs 45 are of a length such that they engage with the
apertures 39 prior to the rotation teeth 44 meeting the locking ring 31.
Engagement of the lugs 45 with the apertures 39 prevents the activator ring 32
from rotating relative to the transfer port 10 and shroud 19, 29. As the accessory
part 8 is pushed towards the main body part 2 (or another accessory part 8) the
rotation teeth 44 engage with the bearing surface 37 of the locking ramps 36.
Figure 28 shows one of the rotation teeth 44 as it is pushed in the direction of
arrow 46. As the activator ring 32 cannot rotate due to the lugs 45 being engaged
in the apertures 39, the rotation teeth 44 bear against the locking ramps 36 and
thus rotate the locking ring in an anti-clockwise direction as shown by arrow 47.
Rotation of the locking ring 31 causes the resilient flanges 35 to flex as the free
ends of the flanges 35 are retained within the grooves 41. This resists the
rotation of the locking ring 31.
Figure 29 shows the position of the locking ring 31 relative to the activator
ring 32 and, in particular, the position of the rotation teeth 44 to the locking
ramps 36 when the connector system 30 is in its locked position. Once each of
the rotation teeth 44 have reached the end of the bearing surface 37, the locking
ring 31 is able to resile back to its original position under the force of the
resilient flanges 35 in direction shown by arrow 48. Accordingly, the rotation
teeth 44 become trapped behind the locking ramps 36 and bear against the
stepped retaining surface 38.
Figure 30 shows the rings 31, 32 connected with the accessory part 8 removed for
clarity. A release aperture 50 is shown in the shroud 19, 29 which allows a tool
to be inserted, which can rotate the locking ring 31 to release the activator ring 32
from the locked position. The rings 31, 32 can thus be separated to detach
accessory part 8 from the main body part 2 (or another accessory part 8). While
Figures 24 to 30 primarily show the interengagement between an accessory part 8
and a main valve body part 2, the same components and principle applies when
connecting a further accessory part 8’ to an accessory part 8.
The connector system 30 may have alternative configurations that allow the
accessory connector 7 or further accessory connector 49 to connect to an
accessory part 8 or further accessory part 8’, 8” respectively. Thus, the accessory
connector 7, 49 will have a first part of the connector system and the accessory
part 8, 8’, 8” will have a complimentary part of the connector system so that the
parts can be securely but removably connected together. In particular, the
connector system may comprise a snap fit system wherein a retaining element is
provided on one part 2, 8, 8’, 8” and a resilient element arranged to engage
behind or within the retaining element is provided on the other part.
Alternatively, the connector system may comprise a grub screw and recess
arrangement. Thus, the accessory connector 7, 49 may include a recess or groove
and the accessory part 8 or further accessory part 8’, 8” may include a grub screw
that can be screwed in to engage with the recess or groove. Alternatively, the
connector system may comprise a bayonet connector. Thus, one of the parts to
be connected may be provided with one or more bayonet connector formations
such as lugs configured to engage one or more mating bayonet connector
formations such as recesses on the other part. The bayonet formations may
engage with a push/twist action and disengage with a reverse action. A biasing
force may be provided that assists maintaining a positive engagement of the
bayonet formations reducing movement (play) between the connected parts and
providing a firm, stable connection between the parts. The biasing force may also
assist separation of the parts when disconnecting the parts. The orientation of the
parts when connected may be defined by employing an asymmetric bayonet
connector system that prevents the parts being assembled incorrectly.
As will be appreciated from the foregoing description, the mixer valve may
include one or more accessory parts, each having different functionality, which
can be selected and assembled in a variety of configurations to customize the
functionality of a shower system employing the mixer valve. Thus, the mixer
valve may have a main body part or control module having a mixing valve for
mixing hot and cold water to provide outlet water having a desired temperature
and a transfer port arranged between the mixing valve and an outlet that, in use,
is connectable to a conduit such as a flexible hose or a rigid pipe for supplying
outlet water from the mixer valve to a shower head. The mixer valve can be
customised by connecting an accessory module to the transfer port. The
accessory module can be a “wet” accessory module that receives or utilises a flow
of outlet water via the transfer port to perform its function. Alternatively, the
accessory module can be a “dry” accessory module that closes the transfer port.
The “wet” accessory module can have the outlet or connect to a further accessory
module having the outlet such that the water flows from the main body part of the
mixer valve through the accessory module(s) to the outlet. Alternatively or
additionally, the main body part may have the outlet. The “wet” accessory
module may utilise the water flow to the outlet to perform a function. For
example, the “wet” accessory module may measure temperature, pressure or flow
rate of the outlet water or introduce a product into the water flow or modify the
water flow or have any other use such as described herein. The “dry accessory
module may perform a function that does not require a fluid flow to perform its
function. For example, the “dry” accessory module may dispense a product or
attach a product or have any other use such as described herein. More than one
accessory module may be provided. Multiple accessory modules may be
connected in series and may comprise “wet” modules or “dry” modules or a
combination of “wet” and “dry” modules. The main body part may have more
than one transfer port for attaching an accessory module. The functionality of the
mixer valve can be changed by adding, removing or replacing an accessory
module to adapt the mixer valve without changing the control module as desired.
