Description

La présente invention a pour objet un dispositif assurant d'une part une extraction d'air d'un local, et d'autre part, une extraction de l'air vicié contenu dans une cuvette d'un appareil sanitaire, en particulier d'une toilette.The present invention relates to a device providing on the one hand an extraction of air from a room, and on the other hand, an extraction of stale air contained in a bowl of a sanitary appliance, in particular of a toilet.

Des systèmes d'extraction d'air d'un local sont bien connus. Ces systèmes aspirent une quantité d'air pour le rejeter vers l'extérieur. De tels systèmes assurent ainsi un renouvellement de l'air du local et donc une ventilation de l'air du local.Room air extraction systems are well known. These systems suck up a quantity of air to reject it to the outside. Such systems thus ensure a renewal of the room air and thus a ventilation of the room air.

On connaît également par des dispositifs d'extraction d'air vicié contenu dans une cuvette d'une toilette (water-closet) via le rebord de distribution d'eau dans la cuvette. Ainsi, par exemple, le document US-A 4,933,996 décrit un dispositif d'évacuation d'air vicié d'une cuvette de water-closet, ce dispositif comportant un ventilateur axial situé dans le réservoir d'une chasse d'eau. Un conduit de refoulement amène l'air vicié dans une canalisation d'évacuation, en aval du siphon à eau. Une valve anti-retour est positionnée à la sortie du ventilateur.Stale air extraction devices contained in a bowl of a toilet (water-closet) are also known via the rim for dispensing water into the bowl. So, for example, the document US-A 4,933,996 discloses a stale air evacuation device of a water closet bowl, this device comprising an axial fan located in the tank of a flush. A discharge pipe brings the stale air into an evacuation pipe, downstream of the water siphon. A non-return valve is positioned at the fan outlet.

Un système qui permet à la fois une extraction de l'air vicié de la cuvette via le rebord de distribution, et une extraction d'air du local en ne passant pas par le rebord de distribution de la cuvette est connu du document DE-A-19950467 .A system that allows both a removal of stale air from the bowl via the dispensing flange, and an extraction of air from the room by not passing through the dispensing rim of the bowl is known from the document DE-A-19950467 .

L'invention a donc pour objet un dispositif permettant une extraction efficiente de l'air vicié situé dans la cuvette par le rebord ou canal de distribution d'eau dans la cuvette, et en même temps une extraction efficiente d'air du local dans lequel se trouve l'appareil sanitaire, cet air du local ne passant pas par le rebord ou canal de distribution d'eau de la cuvette.The invention therefore relates to a device for an efficient extraction of stale air located in the bowl by the rim or water distribution channel in the bowl, and at the same time an efficient extraction of air from the room in which there is the sanitary apparatus, this room air not passing through the rim or channel of water distribution of the bowl.

Un tel dispositif permet ainsi de réduire la nécessité de placer un système de ventilation distinct ou supplémentaire d'un ou de locaux, voire de supprimer la nécessité de placer un système de ventilation distinct ou supplémentaire d'un ou de locaux. Le dispositif suivant l'invention permet ainsi un ou plusieurs avantages choisis parmi : économie d'énergie (un seul moteur pour l'aspiration des odeurs et la ventilation ; aspiration avantageuse d'air du local au niveau de la cuvette, cet air étant moins chaud que l'air adjacent du plafond), assurer une élimination des odeurs à la source (on ne doit plus utiliser des produits désodorisants), une bonne évacuation des odeurs (les odeurs de la cuvette sont mélangées à un volume d'air ne passant pas par le rebord de la cuvette, ceci assurant que les odeurs ne puissent pas rester dans le réservoir et/ou le conduit d'évacuation), assurer un nettoyage de ou des conduites d'évacuation de l'air par l'actionnement de la chasse d'eau (non dépôt de poussières dans cette ou ces conduites, non prolifération d'acariens ou autres parasites dans cette ou ces conduites, d'où réduction de problèmes d'allergies), maintien d'un niveau d'eau suffisant dans le siphon après avoir tiré la chasse en cas de problème d'évacuation (aspiration trop importante due au passage d'eau par le siphon, aspiration due au tirage d'une chasse d'un autre appareil sanitaire, etc.), réduire les problèmes de condensations (les locaux contenant un ou plusieurs appareils sanitaires sont en général plus humides et/ou moins chauffées que des pièces de séjours), éviter que des odeurs ne sortent du local contenant un ou des appareils sanitaires, assurer d'avoir une extraction suffisante pour répondre aux normes européennes de ventilation, non nécessité de devoir ouvrir une fenêtre du local sanitaire (d'où moins de déperditions calorifiques, meilleur confort dans le local sanitaire, moins de sensation de froid, etc.), non nécessité de percer des bouches d'évacuation d'air, de telles bouches constituant une source de déperdition calorifique, moindre problème de fuites d'odeurs dans les canalisations, les odeurs étant chassées vers l'extérieur, etc. 'Such a device thus makes it possible to reduce the need to place a separate or additional ventilation system of one or more rooms, or even to eliminate the need to place a separate or additional ventilation system for one or more rooms. The device according to the invention thus allows one or more advantages chosen from: energy saving (a single motor for the aspiration of odors and ventilation; advantageous aspiration of air from the room to the level of the bowl, this air being less hot air adjacent to the ceiling), ensure elimination of odors at the source (we must no longer use air fresheners), a good evacuation of odors (the smell of the bowl is mixed with a volume of air passing not by the rim of the bowl, this ensuring that odors can not remain in the tank and / or the exhaust duct), ensure cleaning of or ducts of the air evacuation by the actuation of the flushing (no deposit of dust in this or these pipes, non-proliferation of mites or other parasites in this or these pipes, hence reduction of allergy problems), maintaining a sufficient water level in the siphon after firing the in case of evacuation problem (excessive suction due to the passage of water through the siphon, aspiration due to the draw of a flush of another sanitary appliance, etc.), reduce the problems of condensation (the premises containing one or more sanitary appliances are generally wetter and / or less heated than living rooms), to prevent odors from leaving the room containing one or more sanitary appliances, to ensure sufficient extraction to meet European standards ventilation, no need to open a window of the sanitary room (hence less heat loss, better comfort in the sanitary room, less feeling of cold, etc.), no need to drill the evacuation mouths air, such mouths constituting a source of heat loss, less odor leakage in the pipes, odors being expelled to the outside, etc. '

Un même système permet ainsi une extraction d'un volume d'air suffisant pour assurer un renouvellement suffisant d'air dans le local (ou une ventilation du local) et une extraction efficiente de l'air vicié ou des odeurs contenus dans la cuvette. Ce système est de conception simple et, dans ces meilleures formes de réalisation, ne nécessite pas le percement de trous dans les murs pour le passage de conduit d'évacuation.The same system thus allows extraction of a sufficient volume of air to ensure a sufficient renewal of air in the room (or ventilation of the room) and efficient extraction of stale air or odors contained in the bowl. This system is of simple design and, in these best embodiments, does not require the drilling of holes in the walls for the passage of exhaust duct.

L'invention a donc pour objet un dispositif pour l'extraction d'air d'au moins un local et l'évacuation de l'air vicié contenu dans une cuvette tel que défini par la revendication 1 annexée.The invention therefore relates to a device for extracting air from at least one room and exhausting stale air contained in a bowl as defined by appended claim 1.

Dans ce dispositif, le moyen d'aspiration ou d'extraction est un moyen assurant une aspiration ou extraction minimale moyenne d'au moins 15 m3 d'air par heure, avantageusement d'au moins 20m3 d'air par heure, de préférence d'au moins 25 m3 d'air par heure, en particulier de 25 m3 à 100m3 (par exemple de 30 à 60m3) d'air par heure. Cette aspiration ou extraction peut être continue, semi continue ou intermittente.
Dans le dispositif, le moyen d'aspiration ou d'extraction est associé à un élément permettant l'aspiration ou l'extraction d'air du local dans lequel se trouve la cuvette sans passer par le trop-plein et le canal de distribution, ledit élément étant adapté de manière à ce qu'en l'absence de passage d'eau dans la conduite, le rapport volume d'air aspiré ou extrait par le canal de distribution/volume d'air aspiré ou extrait ne passant pas par le canal de distribution est compris entre 0.1 et 5, de préférence entre 0,2 et 3, de préférence entre 0,5 et 2, par exemple compris entre 0,7 et 1,5, en particulier entre 0,7 et 1. Le rapport sera en particulier choisi pour assurer une bonne extraction de l'air vicié de la cuvette ou des odeurs présentes dans la cuvette, tout en assurant que lors du passage d'eau par le canal de distribution, un plus grand volume d'air puisse être aspiré en ne passant pas par le canal de distribution au moins sensiblement sans création de bruits, sifflements et/ou vibrations.In this device, the suction or extraction means is a means ensuring an average minimum suction or extraction of at least 15 m 3 of air per hour, advantageously at least 20 m 3 of air per hour, of preferably at least 25 m 3 of air per hour, in particular from 25 m 3 to 100 m 3 (for example from 30 to 60 m 3 ) of air per hour. This aspiration or extraction can be continuous, semi-continuous or intermittent.
In the device, the suction or extraction means is associated with an element allowing suction or extraction of air from the room in which the bowl is located without passing through the overflow and the distribution channel, said element being adapted so that in the absence of water passage in the pipe, the ratio of the volume of air sucked in or extracted by the distribution channel / volume of air sucked or extracted does not pass through the distribution channel is between 0.1 and 5, preferably between 0.2 and 3, preferably between 0.5 and 2, for example between 0.7 and 1.5, in particular between 0.7 and 1. The ratio will be chosen in particular to ensure a good extraction of the stale air of the bowl or odors present in the bowl, while ensuring that during the passage of water through the distribution channel, a larger volume of air can be sucked by not passing through the distribution channel at least substantially without creating noise s, hisses and / or vibrations.

De façon avantageuse, le conduit de refoulement a une section de passage d'au moins 1cm2, avantageusement comprise entre 1,5cm2 et 100cm2, de préférence entre 3cm2 et 60cm2 . Cette section de passage sera avantageusement déterminée en fonction du débit d'air pour avoir une vitesse d'air appropriée assurant sensiblement l'absence de bruit.Advantageously, the discharge pipe has a passage section of at least 1 cm 2 , advantageously between 1.5 cm 2 and 100 cm 2 , preferably between 3 cm 2 and 60 cm 2 . This passage section will advantageously be determined as a function of the air flow to have a suitable air speed substantially ensuring the absence of noise.

Le dispositif est en particulier conçu pour un appareil sanitaire comportant un réservoir de chasse d'eau. Le moyen d'aspiration ou d'extraction assure une aspiration minimale d'au moins 15 m3 par heure d'air présent dans le réservoir de chasse d'eau, tandis que le réservoir est associé à un ou plusieurs passages permettant l'admission d'air du local dans le réservoir au-dessus du niveau de trop-plein. Le fait que tout l'air passe par le réservoir permet d'éviter que des odeurs ou des traces d'odeur puissent rester dans le réservoir ou puissent sortir du réservoir vers le local. La dimension du ou des passages sera adaptée en tenant compte des éventuelles ouvertures que présente le réservoir, par exemple au niveau du dispositif de commande de la chasse d'eau. La dimension du ou des passages sera également adaptée en fonction de la puissance du moteur, du volume d'air aspiré par le moyen d'extraction, de la présence de diaphragme de contrôle du débit d'air aspiré ou extrait, etc. La surface totale ouverte du
ou des passages est avantageusement comprise entre 2cm2 et 20cm2, de préférence entre 3cm2 et 10cm2.
Le moyen d'aspiration ou d'extraction présente une entrée d'aspiration d'air contenu dans le réservoir située au dessus du niveau du trop-plein, par exemple de 1 à 10 cm au dessus dudit niveau, en particulier de 1 à 5 cm.
Selon une particularité, le moyen d'aspiration ou d'extraction ou, à tout le moins, le moteur électrique entraînant le moyen d'extraction ou d'aspiration est situé au dessus du niveau de trop-plein et présente un passage d'aspiration ou d'extraction d'air contenu dans le réservoir situé au dessus du niveau de trop-plein.
De préférence, le moyen d'aspiration ou d'extraction est situé dans le réservoir à un niveau situé au-dessus du trop-plein ou/et est associé à un passage pour l'aspiration d'air du réservoir, ledit passage étant situé dans le réservoir à un niveau situé au-dessus du niveau de trop-plein (par exemple au moins 1 cm au-dessus du niveau du trop-plein, par exemple de 2 à 5 cm au dessus du trop-plein).
Selon une caractéristique, la valve anti-retour non actionnée électriquement est interposée sur le parcours du conduit de refoulement entre d'une part la sortie de refoulement et d'autre part la canalisation d'évacuation ou sur un boîtier enveloppant le moyen d'aspiration ou d'extraction, en particulier un ventilateur, en amont du moyen d'aspiration ou d'extraction. La ou les valves peuvent donc être montées soit en aval, soit en amont par rapport au moyen d'extraction. Eventuellement, une ou des valves sont montées en aval, tandis qu'une ou des autres valves sont montées en amont.
Selon une autre particularité d'une forme de réalisation, le moyen d'aspiration ou d'extraction est disposé à l'extérieur du réservoir, au moins une entrée (de préférence l'entrée unique) d'aspiration ou d'extraction du moyen d'aspiration ou d'extraction étant en communication directe avec la chambre intérieure du réservoir par l'intermédiaire d'un trou ou passage pratiqué dans la paroi du réservoir, ledit trou ou passage étant situé à un niveau au-dessus du niveau de trop-plein du réservoir (par exemple au moins 1 cm au-dessus du niveau du trop-plein, par exemple de 2 à 5 cm au dessus du trop-plein).The device is in particular designed for a sanitary appliance comprising a flush tank. The suction or extraction means ensures a minimum suction of at least 15 m 3 per hour of air present in the flush tank, while the tank is associated with one or more passages allowing the admission of air from the room in the tank to- above the overflow level. The fact that all the air passes through the tank makes it possible to avoid that odors or traces of odor can remain in the tank or can leave the tank towards the room. The size of the passage (s) will be adapted taking into account any openings that the tank has, for example at the level of the control device of the flush. The size of the passage or passages will also be adapted according to the power of the motor, the volume of air sucked by the extraction means, the presence of suction or extract air control diaphragm, etc. The total open area of the
or passages is advantageously between 2cm 2 and 20cm 2 , preferably between 3cm 2 and 10cm 2 .
The suction or extraction means has an air intake inlet contained in the tank located above the level of the overflow, for example from 1 to 10 cm above said level, in particular from 1 to 5 cm.

La membrane est avantageusement en matière suffisamment souple pour se déformer sous l'effet d'un flux d'air. La membrane est avantageusement associée à un système de rigidification pour empêcher que la membrane puisse passer partiellement ou totalement à travers l'orifice. Selon une autre possibilité, l'orifice comporte un treillis ou des tiges ou un élément filtrant s'étendant dans l'orifice.

Such means are, for example, the use of an insulating or noise-absorbing housing in which the fan is located, the placement of said housing in the tank at least partially below the overflow level, the use of insulating layers. etc.
According to one detail, the non-return valve located upstream of the suction or extraction means is located in the housing enclosing the fan.
For example, the housing comprises one or more orifices, for example circular, square, etc., accommodating or associated with at least one membrane, advantageously circular, square, etc., flexible movable relative to a fixed support, for example placed in a vertical median, the orifice (s) (which when circular, has a diameter slightly smaller than that of the membrane) being slightly inclined (s) to bring back at least by the effect of gravity the membranes to their initial position, that is to say in contact with the walls of the housing. The membrane is advantageously sufficiently flexible material to deform under the effect of a flow of air. The membrane is advantageously associated with a stiffening system to prevent the membrane can pass partially or completely through the orifice. Alternatively, the port has a trellis or rods or a filter element extending into the hole.
According to another characteristic, the non-return valve located downstream of the suction or extraction means and located on the path of the discharge pipe is slightly inclined to resume its initial position under the effect of gravity, this valve advantageously comprising a membrane of sufficiently flexible material to deform under the effect of a flow of air.

Tel que représenté aux figures 1 et 2, l'appareil sanitaire (SA) selon l'invention comprend une cuvette (1) qui présente à sa partie inférieure un rétrécissement (ibis) relié à une canalisation d'évacuation (8) via un siphon (8bis) et au voisinage de son bord supérieur un rebord interne (2). Le dispositif comprend aussi un conduit (3) reliant un canal de distribution (2 bis) situé dans le rebord (2) à une source d'eau, en particulier un réservoir (9) de chasse d'eau pourvu d'un tuyau fixe ou amovible ou mobile (4) formant trop-plein positionné dans le prolongement du conduit (3), ledit conduit (3) permettant le passage d'eau du réservoir (4) vers la cuvette (1) via le canal de distribution (2bis).
La figure 1 montre également que le dispositif comprend un moyen d'aspiration ou d'extraction (13) présentant une ou plusieurs entrées ou bouches d'aspiration ou d'extraction (5) (située au dessus du niveau de trop-plein X) adaptée pour aspirer ou extraire de l'air de la cuvette (1) via le conduit (3) et de l'air situé dans le réservoir (9), et une sortie de refoulement (10) reliée à un conduit de refoulement (7) communiquant avec la canalisation d'évacuation (8) ou la partie du siphon (8bis) tournée vers la canalisation (8), ledit moyen d'aspiration ou d'extraction aspirant de l'air vicié par le canal de distribution (2bis) via le conduit (3) et le tuyau de trop-plein (4) du réservoir (9). Une valve anti-retour (6) est montée sur le conduit de refoulement (7) pour empêcher toute remontée d'odeurs de la canalisation d'évacuation (8) vers le réservoir (9), ladite valve étant avantageusement du type non actionnée électriquement, par exemple du type mécanique.
Dans la forme représentée de la figure 1, le réservoir (9) présente un orifice (11) sur une de ces parois latérales (par exemple la paroi arrière, l'orifice aurait également pu se trouver sur la paroi supérieure), l'orifice (11) étant situé à un niveau au dessus du trop-plein X.
Le dispositif de l'invention permet ainsi une extraction de l'air vicié (A + O: air + odeur) situé dans la cuvette (1) par le rebord ou canal de distribution (2bis) d'eau dans la cuvette, et en même temps une extraction d'air (A : Air) du local dans lequel se trouve l'appareil sanitaire via le réservoir (9) et l'orifice (11), cet air du local ne passant pas par le rebord ou canal de distribution (2bis) d'eau de la cuvette. L'orifice (11) est adapté de manière à ce qu'en l'absence de passage d'eau dans la conduite, le rapport volume d'air aspiré ou extrait par le canal de distribution/volume d'air aspiré ou extrait ne passant pas par le canal de distribution (2bis) est adapté pour assurer une bonne extraction de l'air vicié de la cuvette ou des odeurs présentes dans la cuvette, tout en assurant une bonne extraction d'air du local (de manière à assurer un renouvellement d'air du local ou une ventilation du local, de l'air frais entrant par le dessous de la porte, une fenêtre ou une bouche d'aération).
La section de l'orifice (11) dépendra directement des déperditions d'air autour du système d'actionnement de la chasse (12). Une grille de filtration (11bis) peut être placée devant l'orifice 11. Le moyen d'extraction 13 est dans le cas présent un ventilateur placé dans un double boîtier (97), aspirant l'air du réservoir (9) pour le souffler dans la conduite (8) via la conduite (7) et la valve anti-retour (6). Le débit d'air aspiré et soufflé dans la conduite (8) est par exemple de 25 à 40 m3/heure. L'orifice (11) a une dimension choisie pour que le rapport en volume air aspiré de la cuvette via le canal de distribution/air aspiré du local ne passant pas par le canal de distribution (2bis) est compris entre 0,7 et 1.As represented in FIGS. 1 and 2, the sanitary apparatus (SA) according to the invention comprises a bowl (1) which has at its lower part a constriction (ibis) connected to an evacuation pipe (8) via a siphon (8bis) and in the vicinity of its upper edge an inner rim (2). The device also comprises a conduit (3) connecting a distribution channel (2a) located in the flange (2) to a water source, in particular a tank (9) flush with a fixed pipe or removable or mobile (4) overflow positioned in the extension of the conduit (3), said conduit (3) for the passage of water from the tank (4) to the bowl (1) via the distribution channel (2bis ).
FIG. 1 also shows that the device comprises suction or extraction means (13) having one or more suction or extraction inlets or outlets (5) (located above the overflow level X). adapted to suck or extract air from the bowl (1) via the conduit (3) and air in the reservoir (9), and a discharge outlet (10) connected to a discharge pipe (7). ) communicating with the drain pipe (8) or the portion of the siphon (8a) facing towards the pipe (8), said suction or extraction means sucking air contaminated by the distribution channel (2a) via the pipe (3) and the overflow pipe (4) of the tank (9). A non-return valve (6) is mounted on the discharge pipe (7) to prevent any rising of odors from the discharge pipe (8) to the tank (9), said valve being advantageously of the non-electrically actuated type , for example of the mechanical type.
In the form shown in Figure 1, the reservoir (9) has an orifice (11) on one of these side walls (for example the rear wall, the orifice could also have been on the upper wall), the orifice (11) being located at a level above the overflow X.
The device of the invention thus allows extraction of the stale air (A + O: air + odor) located in the bowl (1) by the rim or distribution channel (2a) of water in the bowl, and same time an extraction of air (A: Air) from the room in which the appliance is located via the tank (9) and the orifice (11), this room air not passing through the rim or water distribution channel (2a) of the bowl. The orifice (11) is adapted so that in the absence of a passage of water in the pipe, the ratio of the volume of air sucked in or extracted by the distribution channel / volume of air sucked or extracted does not not passing through the distribution channel (2bis) is adapted to ensure a good extraction of stale air from the bowl or odors present in the bowl, while ensuring a good air extraction from the room (so as to ensure air renewal of the room or ventilation of the room, fresh air entering from below the door, a window or a vent).
The section of the orifice (11) will directly depend on the air leakage around the hunting actuation system (12). A filtering grid (11a) can be placed in front of the orifice 11. The extraction means 13 is in this case a fan placed in a double casing (97), sucking air from the reservoir (9) to blow it in the pipe (8) via the pipe (7) and the non-return valve (6). The air flow sucked and blown into the pipe (8) is for example 25 to 40 m 3 / hour. The orifice (11) has a dimension chosen so that the volume-to-air ratio sucked from the bowl via the distribution / air channel sucked from the room not passing through the distribution channel (2a) is between 0.7 and 1 .

La conduite (7) a une section de passage transversale de l'ordre de 3 à 30cm2. Cette conduite (7) est lisse à l'intérieur et peut être munie d'une couche d'isolation contre le bruit. Le niveau de bruit mesuré pour le dispositif représenté au figures 1 et 2 était inférieur à 40 dB (de 30 à 35dB). L'amenée de courant au moteur entraînant le ventilateur est par exemple réalisée au moyen d'un câble électrique (CA) protégé passant par l'orifice (11) pour être relié à une source de courant ou une prise électrique.The pipe (7) has a transverse cross section of the order of 3 to 30 cm 2 . This pipe (7) is smooth on the inside and may be provided with a soundproofing layer. The measured noise level for the device shown in Figures 1 and 2 was less than 40 dB (30 to 35 dB). The supply of current to the motor driving the fan is for example carried out by means of a protected electrical cable (CA) passing through the orifice (11) to be connected to a current source or an electrical outlet.

Le dispositif montré aux figures 1 et 2 est ainsi un système apte à extraire un volume d'air important d'un local sans bruit, tout en assurant une bonne extraction des odeurs, un tel dispositif assurant ainsi un renouvellement important d'air du local. Le dispositif ne nécessite pas le placement de canalisation d'évacuation d'air, ni le percement de trou dans le mur.The device shown in FIGS. 1 and 2 is thus a system capable of extracting a large volume of air from a room without noise, while ensuring good extraction of odors, such a device thus ensuring a renewal important local air. The device does not require the placement of exhaust ducting, or the drilling of holes in the wall.

La figure 3 montre une autre forme de réalisation du moyen d'aspiration ou d'extraction. Le moyen d'aspiration ou d'extraction comprend le ventilateur électrique (20) dans son boîtier (21) qui est fixé à l'extérieur du réservoir (22) par encastrement dans un évidemment pratiqué dans celle-ci, tandis que l'entrée d'aspiration ou d'extraction (23) est située à l'intérieur du réservoir (22), ledit trou ou passage (23) étant situé à un niveau au-dessus du niveau de trop-plein (X) du réservoir (par exemple au moins 1 cm au-dessus du niveau du trop-plein, par exemple de 2 à 5 cm au dessus du trop-plein). La figure 3 montre également que le conduit de refoulement (24) relié d'une part au boîtier (21) par sa sortie de refoulement (25) et d'autre part à la canalisation d'évacuation (26) par l'intermédiaire d'un téton (26') est munie d'une valve anti-retour (27) interposée sur son parcours.
Le réservoir (22) présente un orifice (11) dans sa paroi latérale, cet orifice (11) étant placé de manière à assurer une bonne ventilation de l'air contenu dans le réservoir et pour éviter que des odeurs ne puissent rester dans le réservoir.Figure 3 shows another embodiment of the suction or extraction means. The suction or extraction means comprises the electric fan (20) in its housing (21) which is fixed to the outside of the tank (22) by embedding in a recess made in it, while the inlet of suction or extraction (23) is located inside the reservoir (22), said hole or passage (23) being located at a level above the overflow level (X) of the reservoir (by example at least 1 cm above the level of the overflow, for example 2 to 5 cm above the overflow). FIG. 3 also shows that the delivery duct (24) connected on the one hand to the housing (21) via its discharge outlet (25) and on the other hand to the evacuation pipe (26) via a stud (26 ') is provided with a non-return valve (27) interposed on its path.
The reservoir (22) has an orifice (11) in its side wall, this orifice (11) being placed so as to ensure good ventilation of the air contained in the reservoir and to prevent odors from remaining in the reservoir .

La figure 4 représente un urinoir comprenant un dispositif d'évacuation d'air vicié. L'urinoir comprend une cuvette (44) présentant à sa partie supérieure un bord muni d'un rebord (45). L'urinoir présente un embout (55) destiné à être relié à une amenée d'eau (non représentée) munie d'un dispositif de commande manuel et/ou automatique. L'eau arrivant par l'embout (55) passe dans le conduit (56) avant d'être distribuée dans la cuvette (44) par une gouttière intérieure adjacente d'au moins la partie supérieure du rebord (45). L'eau est ainsi distribuée le long du rebord (45). La cuvette (44) est en communication avec une chambre creuse (46) située derrière et sous la cuvette (44) par l'intermédiaire d'orifices (47) et (11). L'orifice (47) est situé au niveau du conduit (56) amenant l'eau vers le rebord de distribution (45). L'orifice 11 est prévu à la partie supérieure de l'urinoir (à un niveau supérieur au niveau de débordement). A sa partie inférieure, la cuvette (44) se rétrécit en une canalisation d'évacuation (48) avec siphon reliée à une fosse de décharge non représentée. Le dispositif comprend un ventilateur électrique aspirant (49) de type centrifuge monté dans un boîtier (50) tel que décrit à la figure 1, l'ensemble étant logé complètement à l'intérieur du réservoir creux (46) au-dessus du niveau de trop plein X-X'. Par ailleurs, une valve anti-retour non actionnée électriquement, schématisée en (51), est connectée d'une part à l'orifice de refoulement (52) du boîtier (50) et d'autre part au conduit de refoulement (53). Un orifice peut avantageusement être prévu à la partie inférieure de l'urinoir de manière à former un passage direct entre le local et la chambre (46) et pour éviter que la chambre ne puisse se remplir d'eau.
Le ventilateur assure ainsi l'aspiration d'odeurs O et d'air A de la cuvette (44) par les ouvertures (47 et 47'), ainsi qu'une aspiration d'air du local ne passant pas par la cuvette (44).Figure 4 shows a urinal comprising a stale exhaust device. The urinal includes a bowl (44) having at its upper portion an edge provided with a flange (45). The urinal has a nozzle (55) intended to be connected to a water supply (not shown) provided with a manual control device and / or automatic. The water flowing through the nozzle (55) passes into the conduit (56) before being dispensed into the bowl (44) through an adjacent inner gutter of at least the upper portion of the rim (45). The water is thus distributed along the rim (45). The bowl (44) is in communication with a hollow chamber (46) located behind and under the bowl (44) through orifices (47) and (11). The orifice (47) is located at the duct (56) bringing water to the distribution flange (45). The orifice 11 is provided at the upper part of the urinal (at a level above the overflow level). At its bottom, the bowl (44) narrows into a drain pipe (48) with siphon connected to a not shown discharge pit. The device comprises a centrifugal type suction electric fan (49) mounted in a housing (50) as described in FIG. 1, the assembly being housed completely inside the hollow tank (46) above the level of too full X-X '. Furthermore, a non-electrically actuated non-return valve, shown diagrammatically at (51), is connected on the one hand to the discharge orifice (52) of the housing (50) and on the other hand to the discharge pipe (53). . An orifice may advantageously be provided at the bottom of the urinal so as to form a direct passage between the room and the chamber (46) and to prevent the chamber can fill with water.
The fan thus ensures the suction of odors O and air A from the bowl (44) through the openings (47 and 47 '), as well as a suction of air from the room not passing through the bowl (44). ).

Les figures 5 et 6 représentent un boîtier (97) dans lequel est placé un ventilateur (13) de type centrifuge destiné pour aspirer de l'air par des orifices (96) de la paroi latérale (95) et pour refouler cet air dans la conduite de refoulement (94). Des membranes souples (98) sont associées aux dits orifices (96). Ces membranes souples (98) sont montées pivotantes ou mobiles par rapport au boîtier (97) entre une position pour laquelle les membranes obturent les orifices (96) (les membranes servant alors de système anti-retour pour empêcher la remontée d'odeur de la canalisation (48) via les ouvertures (47 et 47')), et une position pour laquelle les membranes souples (98) n'obturent pas les ouvertures (96) (position montrée à la figure 6). Le déplacement des membranes se fait avantageusement à l'encontre de l'action d'un moyen de rappel (par exemple la gravité et/ou un moyen élastique, tel qu'une lame ressort) grâce à l'appel d'air créé par le ventilateur ou par la dépression créée par le ventilateur dans le boîtier (97).
Chaque membrane (98) a une surface légèrement supérieure à celle de l'orifice qui doit être obturable par la membrane considérée. Pour éviter que la membrane puisse passer de l'intérieur du boîtier vers l'extérieur du boîtier, la membrane (98) est associée à un renfort (par exemple circulaire, etc.) ou l'orifice (96) est associé à un grillage.
Tous types de valves, en particulier de valves connues, peuvent être utilisées.
Dans la forme représentée, les membranes sont légèrement inclinées en position obturée, l'inclinaison étant choisie ou adaptée pour que la gravité ou pesanteur pousse les membranes vers leur position fermée. L'extrémité libre ou éloignée de chaque membrane est avantageusement associée à un poids ou à une masse pour améliorer l'effet de rappel. Ainsi, dès que le ventilateur est arrêté, les membranes souples obturent les ouvertures (96) de manière à empêcher le passage d'odeurs de la canalisation 48 via le boîtier (50) du ventilateur (49) et via les passages (47,11)
Les membranes sont en matière suffisamment souple pour se déformer sous l'effet d'un flux d'air.FIGS. 5 and 6 show a housing (97) in which is placed a fan (13) of the centrifugal type intended to suck air through orifices (96) of the side wall (95) and to discharge this air into the discharge line (94). Flexible membranes (98) are associated with said orifices (96). These flexible membranes (98) are pivotally mounted or movable relative to the housing (97) between a position for which the membranes close off the orifices (96) (the membranes then serving as a non-return system to prevent the rise of odor of the channel (48) via the openings (47 and 47 ')), and a position for which the flexible membranes (98) do not close the openings (96) (position shown in Figure 6). The displacement of the membranes is advantageously against the action of a biasing means (for example gravity and / or an elastic means, such as a leaf spring) through the air call created by the fan or the depression created by the fan in the housing (97).
Each membrane (98) has a surface slightly greater than that of the orifice which must be closable by the membrane in question. To avoid that the membrane can pass from the inside of the housing to the outside of the housing, the membrane (98) is associated with a reinforcement (for example circular, etc.) or the orifice (96) is associated with a grid.
All types of valves, in particular known valves, can be used.
In the form shown, the membranes are slightly inclined in the closed position, the inclination being chosen or adapted so that the gravity or gravity pushes the membranes to their closed position. The free or remote end of each membrane is advantageously associated with a weight or mass to improve the booster effect. Thus, as soon as the fan is stopped, the flexible membranes seal the openings (96) so as to prevent the passage of odors from the pipe 48 via the housing (50) of the fan (49) and via the passages (47, 11). )
The membranes are sufficiently flexible material to deform under the effect of a flow of air.

La figure 7 montre un dispositif permettant l'aspiration d'air vicié de deux cuvettes (1) d'appareils sanitaires (SA). Ce dispositif comprend un ventilateur central ou un système d'extraction d'air central (100) relié par des conduites (101 , 102) au réservoir (9,9 bis) de chacun desdits appareils sanitaires. La conduite 101 est connectée au réservoir (9) par une ouverture que présente une paroi latérale du réservoir, cette ouverture (103) étant située à un niveau situé au dessus du niveau de trop-plein X-X'. Le réservoir 9 présente une ouverture (11) située au dessus du niveau de trop-plein et agencée pour qu'elle soit plus éloignée de l'ouverture (103) par rapport à la conduite de trop-plein (4). Ceci permet que l'air (A) entrant dans le réservoir (9) pousse vers l'ouverture (103) les odeurs (O) aspirées par la conduite de trop-plein (4).
La conduite (102) présente une portion s'étendant dans le réservoir (9bis), l'extrémité supérieure ouverte (104) de la conduite (102) étant située à un niveau supérieur au niveau de trop-plein X-X'. Le réservoir (9bis) présente une ouverture (11) située au dessus du niveau de trop-plein et agencée pour qu'elle soit plus éloignée de l'ouverture (104) par rapport à la conduite de trop-plein (4).
Les conduites (101, 102) sont avantageusement munies de clapet/valve ou autres systèmes anti-retour pour éviter qu'en cas de non fonctionnement du système d'extraction central que des odeurs ne passent de la conduite (101 ou 102) vers le réservoir (9 ou 9 bis).
Le système d'extraction central ventilateur chasse alors l'air aspiré et les odeurs dans une canalisation, en particulier dans une canalisation d'évacuation d'eau provenant d'appareils sanitaires.
Les réservoirs de chacun desdits appareils sanitaires présentent un orifice permettant une aspiration d'air du local, ledit orifice étant adapté pour assurer que le rapport volume d'air aspiré provenant de la cuvette/ volume d'air aspiré ne passant pas par la cuvette est compris entre 0,7 et 1 pour chacun des appareils sanitaires. Ceci permet une extraction d'air bien répartie dans les différentes toilettes cloisonnées entre elles.Figure 7 shows a device for the extraction of stale air from two bowls (1) of sanitary appliances (SA). This device comprises a central fan or a central air extraction system (100) connected by pipes (101, 102) to the tank (9.9 bis) of each of said sanitary appliances. The pipe 101 is connected to the tank (9) by an opening that has a side wall of the tank, this opening (103) being located at a level above the level of overflow X-X '. The reservoir 9 has an opening (11) located above the overflow level and arranged to be further away from the opening (103) with respect to the overflow pipe (4). This allows the air (A) entering the tank (9) to push towards the opening (103) the odors (O) sucked by the overflow pipe (4).
The conduit (102) has a portion extending into the reservoir (9bis), the open upper end (104) of the conduit (102) being located at a level above the overflow level X-X '. The reservoir (9a) has an opening (11) located above the overflow level and arranged to it is further away from the opening (104) with respect to the overflow pipe (4).
The pipes (101, 102) are advantageously provided with valve / valve or other non-return systems to prevent that in the event of non-operation of the central extraction system that odors do not pass from the pipe (101 or 102) to the tank (9 or 9 bis).
The central fan extraction system then flushes the sucked air and odors into a pipe, especially into a water drain pipe from sanitary fixtures.
The reservoirs of each of said sanitary appliances have an orifice allowing a suction of air from the room, said orifice being adapted to ensure that the ratio of the volume of air sucked from the bowl / volume of sucked air not passing through the bowl is between 0.7 and 1 for each of the sanitary appliances. This allows air extraction well distributed in different toilets partitioned between them.

Il est clair que de nombreuses modifications sont possibles. Le dispositif selon l'invention peut également se présenter sous la forme d'un kit comprenant un dispositif d'extraction relié à un conduit d'aspiration et à un conduit de refoulement, ledit dispositif comprenant en outre un moyen pour placer le dispositif d'extraction à un niveau supérieur au niveau de débordement de la cuvette de l'appareil sanitaire. Le conduit d'aspiration présente au voisinage de son extrémité libre un moyen pour attacher ladite extrémité par rapport à un orifice que présente le réservoir, ledit moyen contrôlant en outre le passage d'air du local vers le réservoir. Le conduit de refoulement présente à son extrémité libre un moyen apte à fixer de manière étanche ladite extrémité sur une conduite d'évacuation.It is clear that many modifications are possible. The device according to the invention may also be in the form of a kit comprising an extraction device connected to a suction duct and to a delivery duct, said device further comprising means for placing the device extraction at a level above the overflow level of the toilet bowl. The suction duct has in the vicinity of its free end means for attaching said end relative to an orifice that has the reservoir, said means further controlling the passage of air from the room to the tank. The discharge pipe has at its free end means adapted to seal said end on a discharge pipe.

Le dispositif suivant l'invention peut être utilisé avec d'autres types d'appareils sanitaires que ceux représentés aux figures, tels que par exemple appareils sanitaires avec chasse murale, etc.The device according to the invention can be used with other types of sanitary appliances than those shown in the figures, such as for example sanitary appliances with wall hunt, etc.

Pour vérifier la bonne extraction des odeurs d'un appareil sanitaire suivant l'invention ou d'un local contenant un appareil sanitaire suivant l'invention et/ou pour vérifier la bonne évacuation des odeurs par une conduite d'écoulement ou par une cheminée et/ou pour détecter des pertes ou fuites d'odeurs (en particulier sensiblement indétectable), on peut opérer de différente manière, telle que par exemple:
On libère ou forme un gaz (identifiable par une caractéristique, par exemple par sa couleur, son opacité, son odeur, etc. ou une combinaison de telles caractéristiques, par exemple sous forme d'une fumée de couleur blanche) dans le local comprenant un ou plusieurs appareils sanitaires et/ou dans la cuvette d'un ou de plusieurs appareils sanitaires et/ou dans le réservoir d'un ou d'appareils sanitaires. Cette libération de gaz est par exemple réalisée au moyen d'une pastille chimique introduite dans la cuvette ou dans le réservoir, où par réaction ou dégradation d'une enveloppe un gaz se forme ou est libéré. Cette libération ou formation de gaz peut également être réalisée au moyen d'un appareil soufflant ledit gaz via une conduite dans la cuvette et/ou dans le local et/ou dans le réservoir et/ou dans la conduite d'évacuation.
On étudie l'évacuation de ce gaz. Cette étude permet ainsi de déterminer si l'extraction d'air du local est suffisante et/ou si l'évacuation des gaz de la cuvette est correcte et/ou si l'évacuation des gaz du réservoir est correct et/ou s'il n'y a pas de perte d'odeur ou de gaz dans les conduites amenant le gaz vers le canal d'évacuation et/ou dans le canal d'évacuation.To check the good extraction of odors of a sanitary appliance according to the invention or a room containing a sanitary appliance according to the invention and / or to check the good evacuation of odors by a flow line or by a chimney and / or to detect losses or leaks of odors (in particular substantially undetectable), one can operate in different ways, such as for example:
A gas is released or formed (identifiable by a characteristic, for example by its color, opacity, odor, etc. or a combination of such characteristics, for example in the form of a white smoke) in the room comprising a or several sanitary appliances and / or in the bowl of one or more sanitary appliances and / or in the tank of one or sanitary appliances. This release of gas is for example carried out by means of a chemical pellet introduced into the cuvette or into the reservoir, where by reaction or degradation of an envelope a gas is formed or is released. This release or formation of gas can also be achieved by means of an apparatus blowing said gas via a pipe in the bowl and / or in the room and / or in the tank and / or in the evacuation pipe.
The evacuation of this gas is studied. This study thus makes it possible to determine whether the extraction of air from the room is sufficient and / or if the evacuation of the gases from the bowl is correct and / or if the evacuation of the gases from the tank is correct and / or if there is no loss of odor or gas in the pipes leading the gas to the evacuation channel and / or the evacuation channel.
