Abstract

The device according to the invention may reduce the total height of the trap along the vertical axis in the direction of gravity while at the same time having a total trap seal height (G1) (G2) and (GN) of at least 50 mm in order to prevent unpleasant smells from travelling back up the pipe and good resistance to the flow of waste water from the pipe (1) towards the tank (2) and ensuring a correct flowrate with an overall height along the vertical axis in the direction of gravity that may even be less than 50 mm. This innovation obeys a very simple mathematical rule: number x height of trap seals = 50 mm. What this means is that we can create one or more traps (fig 1) (fig 2) (fig 3) (fig 4) and (fig 38) comprising independent trap seals (G1) (G2) and (GN) with different heights, namely the total number of these heights of trap seal meeting the standards in force in each country (namely, in the case of the French standard NF : 50 mm).

Description

BONDE ASSEMBLY / DRAIN SIPHON COMPOSED OF SEVERAL

GUARDS OF WATER

In the sanitary sector, the exhaust bung / siphon assembly is manufactured according to the standards in force and must meet at least three important criteria: the height of the water guard which is in the siphon to prevent the ascent bad odors, the resistance to the discharge of wastewater through the channel (1) to the tank (2) and its capacity to evacuate wastewater from the tank (2) to the channel (1). For an evacuation to meet at least these three criteria according to the standards and / or standard certifications of each country, the volume, the size and the height of the siphon in the direction of gravity become important. For example, the NF standard requires a water storage height of 50 mm. Knowing that the diameter of a pipe of a normal drain plug with a horizontal outlet can be 40 mm (very common diameter of standard PVC pipe drain pipes) and counting the height of the water guard in the siphon of this drain plug required by the standard in force of which 50 mm and which must be located before the channel (1) of the wastewater outlet, we arrive at an overall height of 90 mm on the vertical axis in the direction of gravity, which represents the current height for most siphon drain drains on the market. Since this drain must be located at the lowest level of the water receptacle (receiver, sink or sink) for the sewage disposal process to work and taking into account the drainage slope and the thickness of the material with which this receptacle (receiver, sink or sink) is designed, we arrive at least a total height of 14 cm for a shower tray to ask, and much more for a sink or sink.

In the field of medical evacuation and since the creation of the shape of the siphon that creates the water guard, it has never been modified or changed. All the types of evacuation having even different heights of guard of water have always respected this form of guard of water (in horizontal S, in horizontal Z or in U, etc ...) because they answer perfectly and by being very simple to their main role which is to prevent the rise of bad smells. Several manufacturers design various receptacles (receptor, sink or sink, etc.) with possibly a built-in water evacuation (Gl) or other, which make adaptable evacuations on different types of receptacles by reducing height of the water guard so that the overall height of these containers and siphon is the lowest possible for reasons of ease of use or installation. Some evacuations may be adapted with non-return valves that can close the passage of the channel (1) if the flow of water does not take place. It can also prevent the recovery of odors but its viability over time can not be guaranteed 100% because of the normal wear of its material and its mechanism, and if otherwise, residues are in the water to evacuate, these can be stuck in the valve and can prevent its operation.

The device according to the invention, can reduce the total height of the siphon on the vertical axis in the direction of gravity, while having a total height of the water guards (G1) (G2) (GN) of 50 mm at less to prevent the rise of odors and good resistance to the discharge of wastewater from the channel (1) to the tank (2) and respecting a correct flow in a total height of space on the vertical axis in the direction of the gravity which can be even less than 50 mm. This innovation follows a very simple mathematical rule: number x height of water guard = 50 mm. That is to say that we can create one or more siphons (figl) (fig2) (fig3) (fig4) and (fig38) having water guards (Gl) (G2) and (GN) independent with different heights the total number of these heights of water guards meeting the standards in force standard of each country (ie for the French Norm NF: 50 mm). However, we can make evacuations with two, three or more independent and successive water guards, which means, if the water supply in one of the water guards (Gl), dries, it will not influence the level of water in the other water guards (G2) (GN) that are connected to it. In this way, we can create a total height of water guards according to the norms in force, not just on the vertical axis in the direction of gravity, but, at the same time, on the horizontal axis by multiplying the number of water guard on this horizontal axis. Example: we can create a siphon with a height of 40mm, located on the vertical axis in the direction of gravity, and this siphon can have two water guards (Gl) and (G2) successive of 25 mm each. To facilitate fluidity in a low height in the direction of gravity, we can even widen the section of the siphon shape and reduce the height of its bulk on the vertical axis in the direction of gravity while guiding wastewater by a form of two successive U's to create the shapes of the water guards as illustrated in the diagrams (fig3) or (fig4).

The device according to the invention, is an evacuation having several levels of water guards (G1) and (G1), can be designed as follows: a first siphon is molded into the mass of the reservoir (2) to create the shape of the water guard (Gl) obtained by the shapes (10) and (4) with a height (of 40 mm for example) and that this assembly is connected by the side (3) with a second piece (figl) or (fig2) having a siphon shape and having a water depth of 10 mm also located inside the tank (2) as illustrated in the diagrams (fig25) (fig26) and (fig27). ηç. This piece (second siphon) (figl) on the one hand, completes the height of the first water guard (Gl) to meet the standards in force (ie: 40 + 10 = 50 mm "NF") and at the same time it can play a very important role in resisting the discharge of the wastewater from the channel (1) to the reservoir (2). The second water guard that is in the room as shown in the diagrams (figl)

⁷ ^ can be located and connected by the side (3) of the piece (figl) to the outside of the tank (2) as illustrated in the diagrams (figlό) (figl7) (figlδ) (figl9) (fig20) (fig21) ) (fig22) (fig23) and (fig24) or completely independent that can be connected to the evacuation circuit outside the receptacle (receiver, sink or sink etc ..) for the same reasons, that is, that is to say, to complete the height of the water guard so that it g meets the standards in force and for its resistance against the discharge of wastewater. The shape of the tank (2) can be rectangular (figl 3), square (fig25) or in other forms and it can play a very important role to improve the process of evacuation of wastewater to the evacuation channel (1). This tank (2) can have one (fig24), two (fig20) or several slopes (7) thanks to which, on the one hand, they

⁸ ^ can reduce the amount of waste water available in the open air (because the level of wastewater in this tank (2) represents the first height of the water guard (Gl)) and secondly, the slopes (7) act as an accelerator of the wastewater to the outlet channel (1).

The device according to the invention can be composed of the following set as

90 illustrated in (figl 3): a tank (2) having two slopes (7) connected or designed in one piece with a siphon having several successive and independent water guards so that the total height of all guards of water corresponds to the standards in force. This assembly (FIG. 13) can be molded in one piece in a receiver (9) (FIG. 28) (FIG. 29) (FIG. 30) and (FIG. 31) or simply attached to a washbasin or sink (FIG.

⁹⁵ (figl5).

In some cases of shower tray renovation where the wastewater drainage circuits are wall-mounted, it is possible that the connection height to this wastewater drainage circuit is higher than the height (12) of the receiver ( 9). To facilitate the connection installation without doing any work and without changing the

100 height (12) of the receiver (9) and to obtain a correct wastewater evacuation, either the impulse siphoning process for sewage initiation or the continuous pumping process must be created. In this case, we can provide in the siphon (fig39) and (fig40) connection possibilities thanks to the channels (Cl) and (C2) on a pumping system (system of priming by water pressure, maybe be, with i _Q Γ automatic electric detection or mechanical automatic or manual) to initiate and transfer waste water from the tank (2) to the junction connection of wastewater circuits to create the well-known process called siphoning .

The device according to the invention, can demonstrate according to the illustrations (fig39) and (fig40) that the siphon having several heights of waterguards (G1) (G2) and (GN) can have

1 10 one or more channels (C1) and (C2) for connecting (fig39) and (fig40) to a priming pump to empty the water tank (2) by the channel (Cl) and pushed into the channel (C2) towards the direction of the evacuation flow to generate the sewage discharge to the connection connection to the evacuation pipes. Arrows (Fl) (F2) (F3) and (F4) show the sewage flow path that is initiated by

_{1 1} 5 the pump (Pl) to the connection of the sewage systems.

To better explain the illustration (fig39): the arrow (Fl) shows the sewage inlet connected to the tank (2) by the side (3). The arrow (F2) shows the discharge of the wastewater from the drain trap to the circuit which is connected to the sewage pipes. The arrow (F3) shows the connection and direction of the channel (Cl) to the priming pump

120 (Pl). The arrow (F4) shows the direction and connection of the priming pump (Pl) to the channel (C2) towards the direction of the exhaust flow. This assembly can operate by automatic pulses or continuously by a priming pump (Pl) which can be equipped with an automatic on / off detection in the case of priming pulse operation to create the siphoning process .

₁ 25 Pl pump can also operate continuously or without electricity if it is driven by a turbine which itself is driven by the thrust of the water coming out of the fitting. This will greatly increase the discharge rate of wastewater even if the evacuation channels are located higher or lower or at the same level of the receptacle (receiver, sink, sink, etc.) 130 In the case of renovation, if the drainage channel is already embedded in the ground, no installation and no additional equipment is necessary (eg: dump pump / various mechanisms, etc.) to connect the siphon of the receiver to the canal located in the ground so that the process of evacuation of waste water through the water guards (G1) and (GN) can be done properly.

135 It is possible to design shower trays at very low height (12) with several water guards integrated or adapted under the shower tray as shown in (fig37) and (fig38) and very easily connected to the wastewater circuit located in the ground. Pieces (figl) and (fig2) that are used for the second height of the water guard (G2) and the parts illustrated in (fig3) and (fig4) which have a siphon

140 having several waterguards integrated into it on the horizontal axis, can also be designed in a flexible material with a certain rigidity to maintain its position or initial shape (position memory).

This can have two advantages: the first advantage, at the time of installation, the installer can manipulate its shape and block it in a certain position to obtain

145 the appropriate water level for its installation. The second advantage, if it is designed in a flexible material (rubber type, silicone, flexible PU, etc. ..) and if residues remain blocked for example at (Gl) or (G2) within the siphon, the user can easily deform by hand, the shape of the siphon to facilitate the release of residues.

150 However, if it is made of rigid material, one or more opening hatches (5) must be provided to facilitate the release of the jammed residues.

The device according to the invention can be designed according to the illustrations (fig25) (fig26) (fig27) with a height of the first water guard (G1) obtained by the shapes (10) and (4) molded inside tank (2) and connected or molded with the

155 piece (figl) having the second water guard (G2) which is also located inside the tank (2) in a flexible or rigid material.

By creating the two water guards inside the bung / tank (2) this may present another advantage in terms of bulk. This size, which is limited by the dimensions of the tank (2) in which the set of independent water guards is located, facilitates the adaptation and installation of the assembly (plug + siphon) (fig25) in a receiver for tiling for example, as shown in the diagrams (fig35) and (fig36) in the center of a tiling tray to be placed on the floor. The device according to the invention can also be designed as in the illustrations (fig21) (fig22) (fig23) (fig24) having a single slope (7) in a bung / tank

165 rectangular (2) with the first water guard (Gl) (fig44) created by the shapes (10) and (4) which are molded inside the tank (2) and that the assembly is connected to a second piece (fig2) vsituée outside the tank (2) having the second height of water guard (G2). This piece (fig2) having the second height of water guard (G2) can be connected

1 ^ 0 to the various directions in place of the hatches (8) according to the needs of installation to facilitate the connection to the pipe of the sewage evacuation.

The device according to the invention can be designed by two pieces (fig2) and (fig44) forming the two levels of the successive water guards (G1) and (G2) and that all the assembly is placed inside the tank (2) and connected to the pipes of the evacuation of

175 wastewater.
