PIPE CONNECTION FOR A COMBINATION SHOWER-WC
The invention relates to a pipe connection for connecting a combination shower-
WC
bowl to a supply line of a flushing water supply.
Combination shower-WC bowls are attached via a pipe connection to a supply
line of a
flushing water supply. Via this supply line, flushing water flows from the
pipe system via
an inlet collar into the combination shower-WC, which usually is a ceramic
bowl.
Technical progress has improved the development of combination shower-WCs in
the
past. The result of this is that combination shower-WC can carry out many
technical
functions. Thus, as a rule the toilet seat can be pre-heated to body
temperature.
Additionally, from U.S. 6,327,718 a combination shower-WC is known in which
the
water temperature and water pressure can be selected. For this, by means of a
bidet
spray arm, warm water is sprayed. Prior to spraying, the warm water can be
mixed with
air.
It is further known that the toilet seat is equipped with an odor-filtering
ventilator and/or
the bowl itself is provided with an air removal device. JP 07268928 A
describes for this
a combination shower-WC with a device for odor removal. By means of a suction
fan,
gas-forming media are brought out by suction from the interior of the toilet
bowl and
passed to a preparation device. This preparation device comprises a catalytic
converter
containing ozone, which decomposes the odoriferous gases. The air processed in
this
way is released into the environment.
Additionally known from JP 1062530 A is a combination shower-WC, which brings
out
air by suction from the interior of the toilet bowl. In the event the suction
channel
becomes blocked, a measuring device determines that air passage has been
reversed
and issues a signal to a microcomputer, which generates a display from this.
The task of the invention is to provide a pipe connection or an inlet collar
for connecting
a combination shower-WC bowl with a supply line of a flushing water suppiy,
which
improves the design configuration free space of combination shower-WCs.

CA 02816160 2013-04-10
The problem is solved by the pipe connection according to the features of
claim 1.
By this means a pipe connection is provided, which by means of branch arms
creates
interfaces that can combine multiple functions. By shifting the inlet, which
normally is
centered, to the side, space is provided for an improvement of the
installation of the
bidet equipment. Additionally advantageous is that the flushing water is
divided into at
least two channels, and thus flows into the combination shower-WC bowl. This,
the
cleaning of the combination shower-WC bowl is improved.
In a special embodiment form, in the same interface not only is flushing water
supplied,
but in addition an overflow channel and an odor-removal channel are
integrated.
Consequently, water is supplied, odor is removed, and a water heater overflow
is
supplied, with only two branch arms.
It is preferred that the flow channels that direct the flushing water be
situated below.
Insertion of the flow channels guiding the flushing water into the combination
shower-
WC bowl can be so chosen that the flowing of the flushing water permits an
optimal
cleaning of the combination shower-WC bowl. For this, to the flow channel
guiding the
flushing water, an overflow channel of a branch arm can also be integrated
into a pipe
sleeve of the outlet piece. Then each of the channels forms a partial cross
section. It is
preferred that each of the channels covers an essentially halved partial cross
section.
The overflow channel is fed from the water heater.
It is further preferred that the cross section of the branch arm, thus a pipe
sleeve,
exhibits a round cross section that is horizontally divided.
Provision can be made that the invention-specific pipe connection is
accommodated in
an equipment unit, which exhibits a front interface for mounting on a toilet
body and a
rear interface for mounting on an installation surface on the building wall
side.

Figures 1 and 2 show a pipe connection for joining a combination shower-WC
bowl (not
depicted) and a supply line (not depicted) of a flushing water supply. The
invention
deals with a so-called pipe system, which can combine the distribution of
flushing water,
odor removal and outflow of overflow water from a water heater.
For this, the pipe connection comprises an inlet piece 1 and an outlet piece
2. The outlet
piece 2 exhibits at least one first and one second branch arm 3, 4 terminating
in the
combination shower-WC bowl, which each exhibit a first and second flow channel
5 and
6 directing the flushing water.
In addition, the first branch arm 3 exhibits a flow return line 7 for removal
of odor from
the combination shower-WC bowl. The flow return channel 7 can be connected to
a
removal device 9 for suctioning out odor.
The second branch arm 4 can additionally comprise a flow channel 8 for
draining of
overflow water of a water heater. The flow channel 8 can be attached to an
inlet device
for water-heater overflow water.
Thus the flushing water flows through the inlet piece 1 into the pipe
connection or the
pipe system. In the interior, the flushing water is divided into the first and
the second
branch arm 3, 4, and in particular there to the first and second flow channel
5, 6,
directing the flushing water. The flow channels 5, 6 directing the flushing
water
terminate in the combination shower-WC bowl, and in fact preferably with
uniform
openings. By means of the entering flushing water, the combination shower-WC
bowl is
flushed.
One can further see in figure 1 that the cross section of the two pipe sleeves
11, 12 of
the two branch arms 3, 4 is subdivided. The flow channels 5, 6 directing the
flushing
water preferably flow via a part of the pipe cross section, especially in the
lower half
from the pipe connection into the combination shower-WC bowl.
One other part of the pipe cross section, especially preferably an upper half
of the two
pipe sleeves 11, 12 of the two branch arms 3, 4 is a drain. Preferably the
flow return
channel 7 for odor removal forms a vent for release and/or suction removal of
gases.

CA 02816160 2013-04-10
Flow channel 8 for draining of overflow water of the water heater terminates
into the
combination shower-WC bowl.
An upper part, especially an upper half of the pipe sleeve 11 of first branch
arm 3 can
remove odor of the interior of the combination shower-WC bowl. The odor is
drawn off
with the removal device 9, with removal device 9 able to be configured, for
example, as
an elongated slot.
In addition, a filter can be provided after this elongated slot and/or be
integrated.
If the pipe sleeves 11, 12 of the two branch arms 3,4 are configured to be
round,
preferably this round cross section is horizontally divided into the two flow
channels 5, 6
and the flow return channel 7 for odor removal, or the flow channel 8 for
draining
overflow water of a water heater.
As described above, the present invention makes possible better utilization of
a
combination shower-WC. By this means, multiple functions can be integrated
such as
flushing, overflow and odor removal. The design of the branches further makes
it
possible to install devices such as lines for a lower bidet as well as for
further functions
of the combination shower-WC, in compact fashion, centrally, in an
intermediate space.
