DESCRIPTION

Drainage with lighting

The invention relates to a shower drain, comprising:

- a collection plate with an outlet flow opening for connection to an outlet tube;

- a light source; Y

- at least one optical fiber, where a first end is connected to the light source and where the other end extends into the collection plate.

Such shower drain is known from DE 10 2007 057214 A1.

Drains are used, for example, in a sanitary space, such as, for example, a shower space. The drain is incorporated into the soil so that the water that falls can flow over the soil entering the drain and then transported to the drain.

A sanitary space is also provided with lighting. This lighting is usually arranged on the ceiling so that contact with moisture is prevented as much as possible.

However, it is also desirable to have lighting on the floor, and even to have lighting in the drain.

Thus, a drain is known, for example, from document DE 20201105131, where contact points are arranged in the collection plate. A grid, in which the lighting is arranged, is also located in the collection plate. Power is supplied to the lighting through contact points. The drawback of this embodiment is the presence of current in the collection plate. Although it is a weak current, it is not often desired by users. In addition, the contacts may corrode over time, so the lighting may not work properly.

Document DE 102008006749 describes an elongated shower drain with an elongated grid. Lighting modules are arranged on the end surfaces of the grid. These lighting modules include batteries and LED lighting. The shower drain may, therefore, be illuminated for a certain period of time. However, the drawback is that the batteries have to be replaced regularly. The usual shower drain jam makes this an unpleasant task. In addition, the lighting modules take up space in the shower drain, which can affect the ability to drain the shower drain.

In addition, LEDs are sensitive to temperature fluctuations that typically occur in a shower drain. This can considerably limit the life of the LEDs.

In addition, LEDs provide local heating of the shower drain, which can increase the formation of lime debris from the water.

In this document, it is an object of the invention to provide a drainage with illumination, where the aforementioned drawbacks are reduced, or even ignored.

This object is achieved with a shower drain according to the preamble, where the light source is arranged outside the collection plate.

The use of said at least one optical fiber, such as, for example, a fiberglass cable, makes it possible to place the light source on the outside of the collection plate, for example in a dry place. The optical fiber carries the light from the light source to the collection plate, which illuminates the drain. This ensures that electricity and water can be separated from each other at all times.

Due to the placement on the outside of the collection plate, the dimensions of the light source are no longer determined by said collection plate. The light source can also be easily replaced, or a light source that changes color can be arranged.

Another advantage is that the optical fiber is thin, so that the possible excess length can easily be introduced into, for example, the adhesive layer of the tile floor. In addition, a possible break in the optical fiber will not immediately result in problems. The light will usually pass through the break in the fiber. If a break in an electric cable occurs, a short circuit may occur and it would often be necessary to open by breaking the shower floor. This will not happen with the invention.

In an embodiment of the shower drain according to the invention, an interruption, in which the fiberglass cable enters the collection plate, is arranged in said at least one optical fiber.

By arranging an interruption it becomes possible to completely remove the part of the fiberglass in the collection plate, for example in order to clean said collection plate.

The interruption in the optical fiber is preferably provided with at least one lens to allow light from the light source to bridge the interruption.

The use of a lens allows to make light a beam. The light exiting the interruption can, therefore, focus on the remaining part of the fiberglass and / or the light exiting the interruption can be picked up again by the lens and fed again to the remaining part of the fiberglass.

A preferred embodiment of the shower drain according to the invention further comprises a grid that covers the collection plate, and where the other end is arranged on the grill. In this embodiment, the grid is illuminated and can be removed without problem, along with the remaining part of the optical fiber.

The light source preferably comprises at least one LED. LEDs have a long lifespan and also save energy.

In another embodiment of the shower drain according to the invention, a lens is arranged at the other end of the optical fiber, in order to diffuse the light. The light, from the light source, concentrates on the optical fiber. The use of the lens at the other end of the optical fiber allows the concentrated light to diffuse back into the collection plate.

Even in another embodiment of the shower drain according to the invention, the light source is a recessed spot provided with at least one connection for an optical fiber.

With this embodiment, the ceiling of a sanitary space can be provided in the usual way with recessed spotlights. The optical fiber can then be connected to the connection in the recessed spotlight. The advantage of this embodiment is the possibility, by means of the recessed spotlight, to verify if the lighting in the shower drain is working. This is because the optical fiber only carries the light from the recessed spot to the shower drain.

These and other features of the invention are further explained 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 collection plate according to Figure 1.

Figure 1 is a perspective view of a sanitary space with a floor 1, vertical walls 2 and a roof

3. A shower drain 4, in order to collect and discharge water from the shower head 5, is

arranged on the floor 1.

A recessed spotlight 6 is arranged on the ceiling 3. A connection for an optical fiber 7, which runs to the shower drain 4 for illumination, is arranged on this recessed spotlight 6.

Figure 2 shows the recessed spotlight 6 in a cross-sectional view. The recessed spotlight 6 has a housing 8 with a flange 9 and clamping elements 10. The clamping elements 10 ensure that the housing 8 can be placed with elastic jump fixedly within the ceiling 3.

A halogen lamp 11 is arranged in the housing 8 to illuminate the sanitary space. A lens 12, to which the optical fiber 7 is coupled, is also arranged under the halogen lamp 11. The lens 12 concentrates a part of the light, from the halogen lamp 11, and feeds it to the optical fiber 7. The fiber Optics 7 then runs along the wall 2 and the floor 1 to the shower drain 4.

Figure 3 shows the shower drain 4 in cross section. The shower drain 4 has a collection plate 13 with an outlet flow opening 14. The optical fiber 7 runs up to a connection 15 on the side wall of the collection plate 13. Together with a connection 16, this connection 15 forms a interruption in the optical fiber 7. This interruption 15, 16 makes it possible to remove a grid 17 from the collection plate without having to disconnect the optical fiber 7.

The remaining part of the optical fiber 7 is connected to the connection 16 and arranged under the grid 17. In this embodiment, the optical fiber 7 ends at an end point 18 comprising a lens with which light can diffuse from the optical fiber. 7.

The distance between connections 15 and 16 is preferably kept as short as possible and preferably protected against water so that the least possible discontinuity of light occurs in transition 15, 16.
