DK 177469 B1

Toilet Module

FIELD OF THE INVENTION

5

The present invention relates to a toilet module, where undesired water leakage, e.g. from cistern connections inside the wall of the room, is collected and drained from the module in a controlled manner.

10

BACKGROUND OF THE INVENTION

Houses and apartments may be constructed from pre-fabricated modules. A common feature of such modules is that they are either purely wall modules that are mounted 15 together to form a completed unit or that they are complete rooms, such as a bathroom, or portions of a room, such as portions of a living room or family room, that are mounted together to form completed houses or apartments.

EP1959063A2 describes a toilet module formed as a closed room comprising wall sections, 20 a floor comprising a drain pipe connection, a ceiling attached to frame members. There is no disclosure in EP1959063A2 of a recess in a wall enclosing a toilet cistern in accordance with the present invention. The toilet module in EP1959063A2 does not prevent undesired water to leak out from the toilet module.

25 Known wet-room module-based solutions do not sufficiently cope with undesired water leaks in multi-storey houses. Hence, if water is leaking from a cistern, pipe or similar in a toilet module it will migrate and destroy lower placed modules.

One object of the present invention is to overcome that problem in a simple and robust way.

30

It is a further object of the invention to provide a toilet module with low weight, that uses less materials/increases the degree of material utilization, that uses less energy, that has a shorter production time, and requires fewer work hours. A toilet module according to the DK 177469 B1 2 present invention (that is essentially complete prior to arriving at the building site) has very low mounting times at the site.

5 SUMMARY OF THE INVENTION

The present invention solves the problems of the prior art by providing a toilet module comprising: • a closed room with wall panels, floor, and ceiling attached to stiffening 10 members; • a recess in a wall enclosing a toilet cistern and water pipes, a wall unit placed within a wall panel and closed with a board; • a toilet mounted on the board closing the wall unit; • a drainpipe connection in the floor; 15 characterized in that a wet-room membrane is placed inside the recess and said wet-room membrane continues below the entire floor thereby sealing the drainpipe connection.

In a preferred embodiment the stiffening members are made in steel. It is also preferred that the board is a fiber cement board, which is sufficiently strong to hold a toilet. However, 20 the present inventors have also found that a glass board is applicable; especially reinforced glass is suitable, since it is sufficiently strong to carry the toilet. In a particularly preferred embodiment of the present invention the glass board is supported by an inner strong board, such as a cement board; this ensures a robust construction, which is also easy to clean; in this respect it should be recalled that contaminating deposits, such as urine droplets, often 25 accumulates around a toilet. Thus, it is of major importance that the cleaning staff can easily decontaminate the areas adjacent to the toilet.

In a particularly preferred embodiment of the present invention the toilet is equipped with pumping means, such as an air ventilator, for pumping air from the interior of the module 30 through the water inlet of the toilet bowl further to the toilet cistern and into the drainpipe. In this way the toilet module is both ventilated and undesired odours are removed from the module through the drainpipe.

DK 177469 B1 3 A decisive feature of the present invention is the location of the wet-room membrane. First of all it must be placed on the inner surface of the recess in the wall that has the cistern. Secondly, the wet-room membrane must follow a path that ensures correct drainage from the recess to the drainpipe connection in the floor. In a preferred embodiment the wet-room 5 membrane further covers the remaining walls, which ensures that even significant water leaks may be cope with.

In a preferred embodiment of the invention one or more of the stiffening members are formed with one or more slots. The wall elements are attached to the stiffening members 10 such that the slots, which are accessible from outside the module, can be used for example for hanging. The stiffening members may also be formed with additional slots adapted for the attachment of a number of wall elements, such that the stiffening members provide an independent attachment system for the wall elements.

DETAILED DESCRIPTION OF THE INVENTION

25 The present invention will be described in detail below with reference to the figures.

The embodiment in figure 1 and 2 shows a view of the toilet module (1). The module comprises a closed room with wall panels (2) and floor (3) attached to stiffening members (4). One of the wall panels (2a) has recess (5) that encloses a toilet cistern and water pipes.

30 The toilet (8) is hang on a board (9) (e.g fiber cement board and/or strong glass plate for easy cleaning of the wall around the toilet) that closes the recess or wall unit. Importantly a drainpipe connection is provided in the floor. To avoid any damage to adjacent module in a multi-storey building there is inserted a wet-room membrane (11) inside the recess. This DK 177469 B1 4 wet-room membrane continues below the entire floor thereby sealing the drainpipe connection.

The wall panels (2) can be made of different materials, but the panels that face inwards in a 5 wet room must comply with the regulatory requirements for such walls for that particular type of room. On the sides of the wall panels (2) that face outwards there are attached a plurality of fixtures normally found in a bathroom, e.g. a shower, a sink or a basin. In this manner it is simple to adapt the equipment for the physically impaired or other persons with special-needs in terms of placement and mounting height of the fixtures in the bathroom.

10

When the present toilet room module is to be mounted at the building site, it is preferred that it is installed before the roof is attached, such that it can be hoisted directly in place. However, the module can also be installed in areas having a roof by for example wheeling the module in place. When the module is correctly placed, the piping systems are 15 connected to the piping system of the house, drain pipes are connected to the house's drain system and the electrical wiring is connected to the house's power supply. Even though this may require the assistance of authorized craftsmen, the majority of the plumbing and electrical work is done during the manufacture of the module such that the work at the construction site is kept to a minimum.

20

The bathroom floor, which during transportation stands on edge, is preferably ready for use in that it is painted, covered with floor covering. The bathroom floor has a wet-room membrane around its circumference to prevent water leaking out into the adjacent room and thus functions as a container having an outlet in the form of one or more drains.

25

Referring to figure 2 there is shown a cross sectional view of the recess (5) in the wall enclosing the toilet cistern and water pipes. As can be seen the wet-room membrane (11) effectively prevents water from the exiting the module through the wall or the floor. The toilet (not shown) is hang on a board (9) that here consists of a fiber cement board (9a) and 30 strong glass plate (9b) for easy cleaning of the wall around the toilet. This board closes the recess or wall unit. To avoid any damage to adjacent module in a multi-storey building there is inserted a wet-room membrane (11) inside the recess. This wet-room membrane continues below the entire floor thereby sealing the drainpipe connection.
