Definitions

• the present invention relates to the technical sector of devices and methods for eliminating odors from toilets, and makes it possible to evacuate them directly or to recycle them after appropriate filtration / deodorization.
• FIG. 1 provides for drilling through a conduit 6 the rear of the bowl, which would be extremely expensive and is therefore unrealistic.
• FIG. 2 also describes the piercing of the entire tank and is careful not to propose any technical solution for the connection with the bowl, confining itself to representing a purely theoretical solution. It will be seen that the problems thus left open are precisely those which are the most difficult to solve.
• the document in question is limited to proposing an "enhancement", the disadvantage of which is that it is not easily adaptable, that it requires the modification of the sanitary fittings already installed, and above all of the water supply, and to ask often, leakage problems, etc.
• the prior art also poses even more serious hygiene problems, in particular by depositing faeces and urine in the duct, in a location which will never be cleaned.
• the invention also provides significant improvements compared to this document.
• the present invention relates to an improvement to the system which has just been described, which makes it possible, among other improvements, to eliminate the need for an outside air intake and to avoid contact between the water in the flush tank and the 'stale air. This avoids any risk of bacterial proliferation.
• the vitiated air is sucked in at its source, that is to say at the interior of the bowl, by a continuous duct which connects the interior of the bowl to the orifice.
• this tube incorporates or integrates the reservoir overflow tube
• FIG. 1 shows a schematic sectional view of a preferred embodiment of the invention, at the flush tank, in "suction and evacuation of stale air";
• FIG. 2 represents FIG. 1 in “flushing activation” mode.
• the sanitary comprises a bowl C and a flushing tank 1 comprising a cover 2.
• the bowl C communicates by a conduit 10 (formed in the original sanitary) with the lower part of the flush tank, the operating device of which comprises a valve 9 and a tube 7 which serves the case tube overflow for the tank.
• the flushing control system is known and has not been shown.
• the valve 9 and the tube 7 are of known types and need not be detailed.
• the general principle of the invention resides in the permanent suction of the stale air by a continuous duct incorporating or integrating the flushing overflow tube. , leading directly to the VM outlet, and comprising a device ensuring the function of the overflow without contacting the water with the stale air.
• One of the improvements of the invention is to use the original parts and conduits, with a modification of the tank even more minimal than in the aforementioned application FR 97 06935.
• the stale air generated in the bowl C is permanently sucked in by the mechanical ventilation VM, passing through the original duct 10 and the flush toilet duct 7 also original. , before being evacuated via the conduit 4 which extends the conduit 10, the assembly conduit 10 - conduit 7 - conduit 4 forming the continuous conduit of the invention Those skilled in the art will understand that the continuous duct can be manufactured directly in industry, or can be manufactured in separate elements intended to be connected to known sanitary systems.
• said continuous tube may pass directly through the cover 2 of the tank to connect directly to the VM without plunging into water as in the attached figures.
• the continuous duct extends upwards the overflow tube 7 then is bent downwards so as to come out of the tank at any point of the tank invisible to an observer, where it is connected to the outlet of VM .
• the continuous duct completely incorporates or integrates the overflow tube 7, but the invention also covers the variants accessible directly to those skilled in the art and where the continuous duct only partially incorporates or integrates the tube overflow 7.
• the stale air is constantly sucked in (including when the toilet is not in use, the system according to the invention then participating in the normal ventilation of the room).
• the difficulty to resolve came from the fact that it was necessary to maintain the overflow function of the tube 7 without creating a pressure drop on the suction and without bringing the stale air and the water of the reservoir, in order, over long periods, not to create conditions which could be favorable to a bacterial proliferation.
• a bell 20 open downwards, integral with the tube 7 and surrounding this tube outside, the upper part 25 of the bell being placed above the level. normal 6 of the water in the full tank while the lower edge 27 of the bell is plunged a height "e" below this same level.
• One or more orifices 30 are further formed in the conduit 7 to put the interior of this conduit in communication with the interior volume of the bell, above the normal level of water 6 and below the maximum level of safety tolerated for water in the tank.
• the distance (e) is the distance that seals the system, for efficient operation without pressure loss during the suction phase in the bowl. This distance will generally be of the order of a few millimeters to a few centimeters.
• the invention therefore relates to a method for removing stale air from sanitary bowls, characterized in that the stale air generated in the bowl C is sucked in by a continuous duct directly connecting the interior of the bowl C to a suction source of VM, this conduit incorporating or integrating the overflow tube 7, and comprising a bell 20 open downwards, integral with the tube 7 and surrounding this tube at the outside, the top
• the invention also relates to the sanitary facilities of toilets equipped with these devices, as well as the devices themselves, or possibly their separate constituents, and their technical equivalents which will be clear to those skilled in the art.
• the invention also relates to a device for removing stale air from sanitary bowls, characterized in that it comprises a continuous duct directly connecting the interior of the bowl C to a mechanical ventilation suction source VM, this duct incorporating or integrating the overflow tube 7, and comprising a bell 20 open downwards, integral with the tube 7 and surrounding this tube outside, the upper part 25 of the bell being placed above the normal level 6 of the water in the full tank while the lower edge 27 of the bell is plunged from a height "e" below this same level, and in that one or more orifices 30 are further formed in the conduit 7 for put the interior of this duct in communication with the interior volume of the bell, above the normal level of water 6 and below the maximum safety level tolerated for the water in the tank.
• the invention relates to a variant where the device for evacuating stale air from sanitary bowls incorporates or completely integrates the overflow tube 7, as well as the variants, which will be directly accessible to those skilled in the art, where the continuous duct only partially incorporates or integrates the overflow tube 7.
• the device for removing stale air from sanitary bowls is characterized in that the continuous duct extends upwards an overflow tube 7 then is bent downwards so as to come out of the tank at any point on the tank invisible to an observer, where it is connected to the VM socket.
• the invention also relates to the mechanical means and components for the implementation of the method according to the invention, or the production of the devices according to the invention.
