Description

DRAINAGE FROM A WC

TECHNICAL FIELD OF THE INVENTION The invention relates to a drain pipe for a toilet. State of the art

Conventionally when a toilet is blocked. The user seeks to unclog the latter through the opening of the WC. The user often uses a bent metal rod to move or pierce the plug. It turns out that this strategy is unfortunate because even if the plug is removed, the metal rod damages the enamel of the toilet during its movement which will cause a deterioration of the latter and its change.

The safest solution to remove a plug is therefore to go through the toilet outlet in order to gain access to the plug and correct the situation. However, this approach involves separating the toilet and the wastewater drainage system. This operation can be long and possibly require the complete dismantling of the WC. If the room is cramped, disassembly of the toilet and the drainage system takes considerable time.

detailed description

In order to facilitate the operations of accessing a plug located inside a toilet, it is proposed to modify the drain pipe of the toilet or the toilet by using a pipe comprising an access hatch. By WC is meant a toilet device also called a toilet.

The toilet drain line includes a hose that connects the toilet outlet and the inlet of the wastewater drainage system.

As illustrated in Figures 1, 2, 3 and 4, the pipe 1 has an inlet 2 intended to be connected to an outlet from the WC. The pipe 1 also has an outlet 3 intended to be connected to the wastewater evacuation circuit. Inlet 2 and outlet 3 are separated by a flow area.

The innovative pipe 1 has an access hatch 4 which is formed in a side wall of the pipe 1 between the inlet 2 and the outlet 3, that is to say in the flow zone.

In an advantageous embodiment, the flow zone comprises a bend located between the inlet 2 and the outlet 3. The access hatch 4 is formed in the bend so as to have access to the connection which exists between the inlet 2 of the hose and outlet of the toilet without having to dismantle the hose 1.

By installing the access hatch 4 in the elbow, the access hatch 4 is always accessible. It is not obstructed by the toilet outlet and does not interfere with the insertion of inlet 2 of the hose into the toilet outlet.

By installing the access hatch 4 in the elbow, the access hatch 4 allows access to the connection between the pipe 1 and the WC and even to a part of the interior of the WC which facilitates the search for the plug that clogs the toilet.

In another embodiment, the flow zone comprises or is constituted by a rectilinear section which connects the inlet 2 of the pipe and the outlet 3 of the pipe. The access hatch 4 is formed in the rectilinear section so as to have access to the connection which exists between the inlet 2 of the pipe and the outlet of the WC without having to dismantle the pipe 1.

Advantageously, the access hatch 4 is formed less than 20 cm from the inlet 2 of the pipe so that the access hatch 4 is disposed in the immediate vicinity of the connection between the pipe 1 and the WC, which allows easier intervention inside the toilet to find and extract the plug. Preferably, the access hatch 4 is formed within 15cm from the inlet 2 of the pipe and even more preferably within 10cm from the inlet 2 of the pipe.

In a particularly advantageous embodiment, the evacuation outlet of the WC sinks into the inlet of the pipe, the access hatch is configured so that the edge of the access hatch is adjacent to the end of the exit from the toilet. It is particularly interesting to provide that the access hatch area is not partially obstructed by the exit from the WC. In this way, the user has privileged access to the toilet outlet. It can take advantage of the entire surface of the access hatch to find the plug and it is in the immediate vicinity of the toilet outlet, which facilitates intervention. Advantageously, the minimum distance which exists between the edge of the access hatch 4 and the end of the WC outlet is less than 5cm. Even more preferably, the edge of the access hatch closest to the inlet of the pipe is opposite the end of the outlet of the toilet in a direction perpendicular to the longitudinal axis of the pipe or the distance separating these two elements is less than 1cm along the longitudinal axis.

In a particularly advantageous way, in a bent pipe, the section which comprises the access hatch 4 is in direct extension of the outlet from the WC so that by opening the access hatch, the user can move a tool in straight line to reach the toilet exit. Advantageously, the access hatch is arranged so as to allow the introduction of an elongated tool along the longitudinal axis of the portion of the pipe which makes the mechanical connection with the outlet of the WC, which facilitates intervention in seeking a plug.

When the outlet 3 of the pipe is separated from the inlet of the pipe by an elbow, it is advantageous to provide a single access hatch 4 which is formed in the elbow of the pipe 1. This configuration is particularly compact and allows intervention easily in the toilet. Again, it is advantageous to provide that the access hatch is arranged so that the tool inserted through the access hatch moves horizontally and / or in a straight line to the exit of the WC.

To facilitate the intervention in the pipe 1 and / or in the WC, it is preferable to have an access hatch 4 with a large section which places the access hatch 4 on one side or the other of the pipe with respect to the plane of symmetry which exists in an equivalent pipe 1 without access hatch 4. The plane of symmetry advantageously corresponds to the vertical plane when the pipe 1 is installed.

In this configuration, the access hatch 4 defines the direction of use of the hose 1 because the access hatch 4 will only be easily accessible from the right side of the toilet or, on the contrary, from the left side. Depending on the installation configuration of the WC, it will therefore be necessary to use a pipe 1 whose access hatch 4 is located on the right or, on the contrary, is located on the left of the vertical plane of the pipe 1.

In order not to have to choose, it is advantageous to provide a pipe in which two access hatches 4 are formed in the elbow of the flow zone. The two access hatches 4 are formed on each side of the plane of symmetry of the equivalent pipe 1 without an access hatch. Even more advantageously, the two access doors 4 are arranged so as to maintain the plane of symmetry of the pipe with the two doors.

In this configuration, the same pipe 1 can be used in various installations without worrying about the configuration of the WC, that is to say without anticipating whether the best intervention position will be on the right side or on the side. left of the toilet.

In a particularly advantageous manner, in order to keep a pipe 1 compact and easy to use, it is advantageous to provide that the opening plane in the elbow of the pipe 1 to form the access hatch is a plane which is not parallel to the plane of symmetry of the pipe in the absence of access hatch 4. It is preferable to have a pipe 1 whose cutting plane of the side wall is not a vertical plane.

Even more advantageously for optimal integration of the access hatches 4 in the pipe 1, it is advantageous that the intersection of the two section planes defining the two access doors 4 is located along the plane of symmetry of the pipe 1 The inlet of the pipe 1 has a first area, that is to say a first surface value making it possible to insert the outlet of the WC or making it possible to let the flow of waste water pass. In order to facilitate intervention in the pipe and especially in the WC, the access hatch 4 has a second area at least equal to 50% of the first area.

Advantageously, the first area has a circular section, but other shapes are also possible.

Preferably, the area of the access hatch 4 is circular in shape, but other shapes are also possible.

When the inlet 2 has a circular section with a first diameter, it is also advantageous to provide that the access hatch 4 has a second diameter at least equal to 70% of the first diameter and preferably less than the first diameter. In this way, the user can easily intervene in the pipe 1 without being hampered by a possible narrowing due to the access door 4.

By limiting the upper diameter of the access hatch 4 to that of the inlet 2 of the pipe 1, the access hatch 4 does not interfere too much with the flow of the wastewater stream.

For an easy introduction of a search tool, it is particularly advantageous if the area of the access hatch is at least equal to 8 cm 2 or at least equal to 10 cm 2.

Although many tools are available and usable, it is preferable to provide that the access hatch 4 has a section configured to allow the introduction of a hand of a user. This specific feature makes it easier for non-expert people to use the hose. This is why an area of the access hatch at least equal to 50 cm 2 is advantageous. However, in order not to weaken the pipe, it is preferable not to install an access hatch with an area greater than 100cm2.

In an exemplary embodiment, the inlet 2 and the outlet 3 are circular and the pipe 1 defines a section plane passing through a diameter of the inlet and a diameter of the outlet. The access hatch 4 preferably has a circular section with an axis of revolution perpendicular to the cutting plane. However, it may be advantageous to provide that the axis of revolution is offset from the perpendicular to the cutting plane by an angle less than 30 ° relative to the cutting plane or preferably between 5 ° and 30 ° because this facilitates the 'intervention in confined spaces. The offset angle is defined by taking a vertical section plane and with an axis of revolution contained in another vertical section plane and orthogonal to the previous section plane.

When the inlet of the pipe has a circular section, it is advantageous to provide that the inlet has a first section authorizing the introduction of the outlet of the WC and then a second section corresponding to the nominal diameter of the pipe. The transition from the first section to the second section takes place through a transition zone. It is particularly advantageous that the access hatch does not encroach on the transition zone and even more advantageous that the edge of the access hatch is located at the interface between the transition zone and the zone with the second section. . Depending on the configuration, the first section or the second section defines the inlet area of the pipe. In a privileged way, the second section defines the entry area of the pipe. The access hatch is preferably defined only in the portion having the second section.

The access door 4 is impermeable to odors and / or moisture.

The access hatch 4 has a plug which is removably mounted with respect to the pipe 1. The plug makes it possible to seal.

In a particularly advantageous embodiment, the plug is mounted removable in rotation relative to the pipe 1, for example with a screw thread which allows easy mounting and dismounting even when the access hatch is not very accessible. However, other embodiments are also possible with assembly / disassembly in translation. The plug can also be fixed with clamps, screws or a valve system.

As indicated above, the pipe 1 can also be formed by a straight section which directly connects the inlet 2 and the outlet 3. The different configurations presented for a bent pipe are also possible.

In a straight pipe with a circular or other section, it is particularly advantageous to provide a single access hatch 4 because the pipe can be turned during its installation in order to adapt to the configuration of the premises. During assembly, it is advantageous to place the access hatch in the upper half of the pipe in a horizontal section plane or at least outside the lower third of the pipe.

As with the bent pipe, when the inlet 2 has a section with a first area, the access hatch 4 advantageously has a second area at least equal to 50% of the first area.

Also advantageously, when the inlet 2 has a circular section with a first diameter, the access hatch 4 can have a second diameter at least equal to 70% of the first diameter and preferably less than the first diameter. Again, it is advantageous that the access door 4 has a section configured to allow the introduction of a hand of a user.

Advantageously, the pipe 1 has a seal on its inlet 2 and / or on its outlet so as to facilitate its connection with the WC and / or the waste water evacuation circuit.

The pipe is advantageously made of plastic material and even more advantageously of PVC, but it can also be made of metal, cast iron, steel or other materials.

If the pipe has different sections between the inlet and the outlet, it is advantageous that the area of the access hatch is defined relative to the area of the pipe in the flow zone immediately adjacent to the hatch. '' access 4.
