DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a WC module which can be installed in any public premises, such as a railway station, airport, market place etc. It can also be installed, for example, in connection with a ship cabin., as WC premises.
According to a known method, WC modules are constructed so that all the fixtures required, such as the WC bowl, washbasin etc are already installed in the WC premises at the factory. Thus, at the installation site these fixtures only need to be connected to the water pipes and sewer. Thanks to the preliminary work carried out at the factory, significantly less valuable installation time is spent on constructing the WC module on site.
Despite the work done at the factory, however, WC premises have not become simpler. All fixtures still require their own space in the WC. Due to the complexity of the premises, cleaning them is also inconvenient.
SUMMARY
An object of the present invention is, therefore, to achieve a WC module, which is essentially simpler than present premises and thus also more efficient in use and easier to clean. According to the invention, the module does not have a separate WC bowl, but it is incorporated directly as a continuation of the wall structure of the module. Thus, the WC no longer has to be made of separate components. The design and structure of the WC module relating to the invention incorporates all the equipment necessary in a WC.

FIG. 8 corresponds to FIG. 6 and shows a third embodiment of the toilet paper.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
FIG. 1 shows a partly cross-sectional view of the WC module 10 relating to the invention. The figure shows that the module does not comprise a separate WC bowl 11. Instead, the inner surface of the module 10 is designed so that the WC bowl 11 is a direct continuation of the curved wall surfaces 12. The bowl 11 is flushed by running flushing water from the nozzles 13 on the wall 12 down the wall surfaces into the bowl 11. The water tank 29 can be situated in the upper part of the module, hidden behind the curved inner wall 12.
The module 10 does not comprise a traditional, fixed WC seat for sitting on either, because the WC bowl is an integral part of the wall. In the WC module relating to the invention, the WC seat is arranged so that on the rear wall of the module 10, there are seat boards 15, which are turned down on a hinge 14, and rise up again after use. Above the seat boards 15 is a toilet paper roll rack 16, because the toilet paper is also used as covering for the seat 15. The paper is, therefore, in sock-like form so that it can be pulled over the seat boards.
A handle 25 and a light fixture 26 are connected to the inner surface 12 of the WC module 10, and on the floor level a floor drain is formed, which is covered by a grating 17. A separate water feeder is led to the floor drain, which feeder flushes the space below the grating 17 at the same time as the WC bowl 11 is flushed.
FIG. 2 shows the WC module of FIG. 1 as seen from the front. It also clearly shows how the WC bowl 11 is a continuation of the curved walls 12. The flushing water is fed from nozzles 13 along the walls 12 into the bowl 11 and further on to the sewer 18. In this example, the nozzles are separate elements, but it is also possible to make a fold or other protrusion in the wall, which can as such act as a flushing water nozzle. The floor drain below the floor
