[0001] The invention relates to a shower drain, comprising:
- a collecting tray with an outflow opening for connection to an outlet pipe;
- a light source; and
- at least one optical fibre, wherein the one end is connected to the light source and
wherein the other end extends into the collecting tray
[0003] Drains are for instance used in a sanitary space, such as for instance a shower space.
The drain is incorporated in the floor so that falling water can flow over the floor
into the drain and then be carried to the sewer.
[0004] A sanitary space is further provided with lighting. This lighting is usually arranged
in the ceiling so that contact with moisture is prevented as far as possible.
[0005] It is nevertheless desired to also arrange lighting in the floor, and to even arrange
lighting in the drain.
[0006] A drain is thus known from for instance
DE 20201105131 wherein contact points are arranged in the collecting tray. A grating in which lighting
is arranged is further provided in the collecting tray. The lighting is supplied with
current via the contact points. The drawback of this embodiment is the presence of
current in the collecting tray. Although it is a weak current, it is often undesired
by users. In addition, the contacts may corrode in the course of time, whereby the
lighting may not function properly.
[0007] DE 102008006749 describes an elongate shower drain with an elongate grating. Lighting modules are
arranged on the end surfaces of the grating. These lighting modules comprise batteries
and LED lighting. The shower drain can hereby be illuminated for a certain period
of time. The drawback however is that the batteries have to be replaced regularly.
The usual fouling of the shower drain makes this is an unpleasant task. The lighting
modules moreover take up space in the shower drain, which may affect the drainage
capacity of the shower drain.
[0008] In addition, LEDs are sensitive to the fluctuations in temperature which typically
occur in a drain for a shower. This can considerably limit the lifespan of the LEDs.
[0009] The LEDs moreover provide for local heating of the shower drain, which may enhance
formation of limescale from the water.
[0010] It is now an object of the invention to provide a drain with lighting, wherein the
above stated drawbacks are reduced or even obviated.
[0011] This object is achieved with a shower drain according to the preamble, wherein the
light source is arranged outside the collecting tray.
[0012] The use of the at least one optical fibre, such as for instance a glass fibre cable,
makes it possible to place the light source outside the collecting tray, for instance
at a dry location. The light from the light source is carried by the optical fibre
to the collecting tray, where it illuminates the drain. This ensures that the electricity
and the water can be separated from each other at all times.
[0013] Because of the placing outside the collecting tray, the dimensions of the light source
are no longer determined by the collecting tray. The light source can further be easily
replaced, or a colour-changing light source can be arranged.
[0014] Another advantage is that the optical fibre is thin, whereby possible excess length
can be easily worked into for instance the adhesive layer of the tile floor. In addition,
a possible break in the optical fibre will not immediately result in problems. The
light will usually pass through the break in the fibre. If a break were to occur in
an electric wire, short-circuiting could occur and it is often necessary to break
open the shower floor. This will not be the case with the invention.
[0015] In an embodiment of the shower drain according to the invention an interruption where
the glass fibre cable enters the collecting tray is arranged in the at least one optical
fibre.
[0016] Providing an interruption makes it possible to wholly remove the part of the glass
fibre in the collecting tray, for instance for the purpose of cleaning the collecting
tray.
[0017] The interruption in the optical fibre is preferably provided with at least one lens
to allow the light from the light source to bridge the interruption.
[0018] The use of a lens enables the light to be bundled. The light exiting at the interruption
can hereby be focussed on the remaining part of the glass fibre and/or the light exiting
at the interruption can be collected again by the lens and fed back into the remaining
part of the glass fibre.
[0019] A preferred embodiment of the shower drain according to the invention further comprises
a grating which covers the collecting tray, and wherein the other end is arranged
on the grating. In this embodiment the grating is illuminated and the grating can
be removed without problem, together with the remaining part of the optical fibre.
[0020] The light source preferably comprises at least one LED. LEDs have a long lifespan
and are in addition energy-saving.
[0021] In another embodiment of the shower drain according to the invention a lens is provided
on the other end of the optical fibre for the purpose of diffusing the light. The
light from the light source is concentrated in the optical fibre. The use of the lens
at the other end of the optical fibre enables the concentrated light to be diffused
again in the collecting tray.
[0022] In yet another embodiment of the shower drain according to the invention the light
source is a build-in spotlight provided with at least one connection for an optical
fibre.
[0023] With this embodiment the ceiling of a sanitary space can be provided in a usual manner
with build-in spotlights. The optical fibre can then be connected to the connection
on the build-in spotlight. The advantage of this embodiment is that it is possible
by means of the build-in spotlight to check whether the lighting in the shower drain
is functioning. This is because the optical fibre only carries the light from the
build-in spotlight to the shower drain.
[0024] These and other features of the invention are further elucidated with reference to
the accompanying drawings.
Figure 1 is a perspective view of an embodiment of the drain according to the invention.
Figure 2 is a cross-sectional view of the light source according to figure 1.
Figure 3 is a cross-sectional view of the collecting tray according to figure 1.
[0025] Figure 1 is a perspective view of a sanitary space with a floor 1, upright walls
2 and a ceiling 3. Arranged in floor 1 is a shower drain 4 for the purpose of collecting
and discharging water coming from shower head 5.
[0026] A build-in spotlight 6 is arranged in ceiling 3. Provided on this build-in spotlight
6 is a connection for an optical fibre 7 which runs to shower drain 4 for illumination
thereof.
[0027] Figure 2 shows build-in spotlight 6 in cross-sectional view. Build-in spotlight 6
has a housing 8 with a flange 9 and clamps 10. Clamps 10 ensure that housing 8 can
be snapped fixedly into ceiling 3.
[0028] A halogen lamp 11 is provided in housing 8 for lighting the sanitary space. A lens
12 to which optical fibre 7 is coupled is also provided under halogen lamp 11. Lens
12 concentrates a part of the light from halogen lamp 11 and feeds it to optical fibre
7. Optical fibre 7 then runs through wall 2 and floor 1 to shower drain 4.
[0029] Figure 3 shows shower drain 4 in cross-section. Shower drain 4 has a collecting tray
13 with an outflow opening 14. Optical fibre 7 runs to a connection 15 on the side
wall of collecting tray 13. Together with connection 16 this connection 15 forms an
interruption in optical fibre 7. This interruption 15, 16 makes it possible to remove
grating 17 from the collecting tray without optical fibre 7 having to be disconnected.
[0030] The remaining part of optical fibre 7 is connected to connection 16 and arranged
under grating 17. In this embodiment the optical fibre 7 ends at an end point 18 which
comprises a lens with which the light from optical fibre 7 can be diffused.
[0031] The distance between connections 15 and 16 is preferably kept as short as possible
and preferably shielded from the water so that the least possible disruption of the
light occurs at transition 15, 16.
