Description

La présente invention concerne un appareil sanitaire pour l'évacuation forcée d'eaux usées par l'intermédiaire d'un dispositif de pompage et de broyage, plus particulièrement destiné à être installé dans les cabinets d'aisances.The present invention relates to a sanitary appliance for the forced evacuation of waste water by means of a pumping and grinding device, more particularly intended to be installed in lavatories.

On connaît, par le brevet FR-A-2 607 843, un tel appareil sanitaire comportant une cuvette reliée, à sa partie inférieure, à un siphon et présentant, à sa partie supérieure, un conduit d'amenée d'eau de rinçage. De plus, un dispositif de pompage et de broyage des eaux usées est raccordé, d'une part à la cuvette et, d'autre part à l'entrée d'un conduit d'évacuation des eaux usées. Ce dispositif comprend un moteur solidaire d'un corps de pompe dans lequel sont logées des pales montées sur l'arbre d'entraînement du moteur.We know, from patent FR-A-2 607 843, such a sanitary appliance comprising a bowl connected, at its lower part, to a siphon and having, at its upper part, a pipe for supplying rinsing water. In addition, a device for pumping and grinding waste water is connected, on the one hand to the bowl and, on the other hand to the inlet of a waste water evacuation pipe. This device comprises a motor integral with a pump body in which are housed blades mounted on the motor drive shaft.

Dans ce cas, l'ensemble moteur-pompe est suspendu élastiquement à l'arrière de la cuvette, et la pompe est disposée horizontalement au-dessous du moteur. La suspension dudit ensemble a pour but d'éliminer les vibrations et bruits du moteur lors du fonctionnement de l'appareil sanitaire.In this case, the motor-pump assembly is suspended elastically at the rear of the bowl, and the pump is arranged horizontally below the motor. The purpose of suspending said assembly is to eliminate vibrations and noises from the engine when the sanitary appliance is operating.

Cependant, cette disposition de la pompe au-dessous du moteur place obligatoirement les pales de la pompe dans une position proche du "plafond" du corps de pompe. L'air, plus léger que les eaux usées traversant le corps de pompe, a tendance à occuper la partie supérieure de ce dernier au voisinage des pales. Afin d'éviter l'apparition du phénomène de cavitation dans la pompe, on prévoit, dans l'appareil décrit dans FR-A-2 607 843, une conduite de refoulement surélevée dans le but d'évacuer l'air emprisonné dans le corps de pompe. Cette solution assure, tout au moins dans une certaine mesure, l'amorçage de la pompe après une période de repos et au moment du démarrage du cycle suivant, mais ne résout pas les problèmes engendrés par l'air aspiré avec les eaux usées traversant la pompe pendant le cycle de fonctionnement de l'appareil. Cela entraîne inévitablement une diminution des capacités de ladite pompe et une augmentation importante des bruits de fonctionnement en raison de la présence du mélange eaux usées - air autour des pales. Cette augmentation des bruits dépasse largement le gain obtenu par la suspension élastique.However, this arrangement of the pump below the motor necessarily places the blades of the pump in a position close to the "ceiling" of the pump body. The air, lighter than the waste water passing through the pump body, tends to occupy the upper part of the latter in the vicinity of the blades. In order to avoid the appearance of the cavitation phenomenon in the pump, there is provided, in the apparatus described in FR-A-2 607 843, an elevated delivery pipe in order to evacuate the air trapped in the body. pump. This solution ensures, at least to some extent, priming the pump after a rest period and when starting the next cycle, but does not solve the problems caused by the air sucked in with the waste water passing through the pump during the operating cycle of the device. This inevitably leads to a reduction in the capacities of said pump and a significant increase in operating noise due to the presence of the wastewater - air mixture around the blades. This increase in noise far exceeds the gain obtained by the elastic suspension.

De plus, dans certains cas particuliers dans lesquels l'appareil sanitaire est raccordé à une canalisation du réseau formant un siphon extérieur ou descendant en forte pente, le corps de pompe, après l'actionnement de l'appareil, peut être vidé partiellement de son liquide, ce qui provoquerait le désamorçage de la pompe puisque les pales sont situées dans la partie supérieure du corps de pompe. Et, par la même occasion, cela provoquerait la vidange de la cuvette qui, se trouvant démunie de sa garde d'eau, causerait des remontées d'odeurs.In addition, in certain special cases in which the sanitary appliance is connected to a network pipe forming an external siphon or descending steeply, the pump body, after actuation of the appliance, can be partially emptied of its liquid, which would cause the pump to defuse since the blades are located in the upper part of the pump body. And, at the same time, it would cause the emptying of the bowl which, finding itself deprived of its water guard, would cause rising odors.

La présente invention a pour but de remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

A cet effet, l'appareil sanitaire pour l'évacuation forcée d'eaux usées, du type comportant une cuvette présentant, à sa partie inférieure, un siphon et, à sa partie supérieure, un conduit d'amenée d'eau de rinçage, et un dispositif de pompage et de broyage des eaux usées, raccordé, d'une part à la sortie du siphon et, d'autre part à l'entrée d'un conduit d'évacuation des eaux usées, ledit dispositif comprenant un moteur solidaire d'un corps de pompe, dans lequel est logé un rotor monté sur l'arbre d'entraînement dudit moteur, est remarquable, selon l'invention, en ce que ledit dispositif de pompage et de broyage est agencé au-dessous de la sortie dudit siphon, ledit corps de pompe étant disposé au-dessus dudit moteur d'entraînement.For this purpose, the sanitary appliance for the forced evacuation of waste water, of the type comprising a bowl having, at its lower part, a siphon and, at its upper part, a pipe for supplying rinsing water, and a device for pumping and grinding waste water, connected, on the one hand to the outlet of the siphon and, on the other hand to the inlet of a pipe for discharging waste water, said device comprising an integral motor a pump body, in which is housed a rotor mounted on the drive shaft of said motor, is remarkable, according to the invention, in that said pumping and grinding device is arranged below the outlet of said siphon, said pump body being disposed above said drive motor.

Ainsi, l'agencement du dispositif de pompage et de broyage au-dessous de la sortie du siphon, et du corps de pompe au-dessus du moteur d'entraînement assure une position idéale pour le rotor qui est, de ce fait, constamment immergé car il se trouve au "fond" du corps de pompe. L'air éventuellement aspiré avec les eaux usées reste toujours à un niveau supérieur à celui du rotor et n'affecte donc pas le fonctionnement de la pompe. En particulier, l'apparition de tout phénomène de cavitation et/ou le risque de désamorçage de la pompe sont évités.Thus, the arrangement of the pumping and grinding device below the outlet of the siphon, and of the pump body above the drive motor ensures an ideal position for the rotor which is, therefore, constantly submerged because it is at the "bottom" of the pump body. The air possibly drawn in with the wastewater always remains at a level higher than that of the rotor and therefore does not affect the operation of the pump. In particular, the appearance of any cavitation phenomenon and / or the risk of defusing the pump are avoided.

Avantageusement, ledit siphon fait partie intégrante de ladite cuvette et un raccord souple coudé relie, avec étanchéité, la sortie dudit siphon à l'entrée dudit corps de pompe. On assure ainsi la fixation élastique du dispositif de broyage à la cuvette.Advantageously, said siphon is an integral part of said bowl and a flexible bent connector connects, with sealing, the outlet of said siphon to the inlet of said pump body. This provides elastic fixing of the grinding device to the bowl.

De préférence, la sortie du siphon s'étend horizontalement à l'arrière de ladite cuvette et l'ensemble moteur-pompe est disposé verticalement au-dessous de ladite sortie.Preferably, the outlet of the siphon extends horizontally at the rear of said bowl and the motor-pump assembly is arranged vertically below said outlet.

Selon une autre caractéristique de l'invention, ledit rotor comporte une pluralité de pales pour broyer les matières organiques et fibreuses contenues dans les eaux usées.According to another characteristic of the invention, said rotor comprises a plurality of blades for grinding the organic and fibrous materials contained in the wastewater.

Selon encore une autre caractéristique de l'invention, ledit corps de pompe présente une sortie latérale horizontale et ledit conduit d'évacuation des eaux usées, raccordé à ladite sortie, remonte verticalement.According to yet another characteristic of the invention, said pump body has a lateral outlet horizontal and said waste water evacuation pipe, connected to said outlet, rises vertically.

Pour caler l'ensemble moteur-pompe, le fond du moteur coopère avantageusement avec la base du socle de la cuvette par une liaison rainure-languette. En particulier, ladite rainure peut être ménagée dans le fond dudit moteur tandis que la languette fait alors saillie de ladite base dudit socle. De plus, entre la rainure et la languette peut être disposée une bande en matière élastique.To stall the motor-pump assembly, the bottom of the motor advantageously cooperates with the base of the base of the bowl by a groove-tongue connection. In particular, said groove can be made in the bottom of said motor while the tongue then projects from said base of said base. In addition, between the groove and the tongue can be arranged a strip of elastic material.

Généralement, l'appareil est du type comportant, à la partie supérieure de ladite cuvette, une chambre de distribution de l'eau de rinçage. Dans ce cas, selon l'invention, une paroi de ladite chambre de distribution présente une ouverture pour le raccordement du conduit d'eau de rinçage, dont la géométrie est telle que, une fois le conduit en place, au moins un passage d'air demeure entre ledit conduit et le bord de ladite ouverture.Generally, the device is of the type comprising, at the upper part of said bowl, a chamber for dispensing rinse water. In this case, according to the invention, a wall of said distribution chamber has an opening for the connection of the rinsing water pipe, the geometry of which is such that, once the pipe is in place, at least one passage for air remains between said duct and the edge of said opening.

Selon un exemple de réalisation, ladite ouverture est définie par un trou central de montage dudit conduit et deux passages d'air, en forme de croissant, disposés respectivement de part et d'autre dudit trou central.According to an exemplary embodiment, said opening is defined by a central mounting hole for said duct and two crescent-shaped air passages, disposed respectively on either side of said central hole.

Selon un autre exemple de réalisation, ladite ouverture est définie par un trou central de montage dudit conduit et un passage d'air relié audit trou central et débouchant dans le plafond de ladite chambre de distribution.According to another embodiment, said opening is defined by a central hole for mounting said conduit and an air passage connected to said central hole and opening into the ceiling of said distribution chamber.

Selon une autre caractéristique de l'invention, l'appareil comprend un dispositif de commande sans contact de son cycle de fonctionnement.According to another characteristic of the invention, the device comprises a contactless control device for its operating cycle.

Avantageusement, ledit dispositif de commande sans contact comprend au moins une cellule photoélectrique qui débouche sur une paroi latérale de la partie supérieure dudit appareil.Advantageously, said contactless control device comprises at least one photoelectric cell which opens onto a side wall of the upper part of said device.

La figure 7 est une vue agrandie dudit dispositif de commande associé à l'appareil.Figure 7 is an enlarged view of said control device associated with the device.

En se référant à la figure 1, l'appareil sanitaire 1 pour l'évacuation forcée d'eaux usées comporte une cuvette 2 présentant, à sa partie inférieure, un siphon 3. Comme montré sur la figure 1, le siphon 3 peut faire partie intégrante de la cuvette 2 et être réalisé, comme cette dernière, en céramique, grès ou analogue. Ce siphon 3 présente, à l'arrière de la cuvette 2, une sortie horizontale 4 au-dessous de laquelle est agencé, selon l'invention, un dispositif de pompage et de broyage 5 des eaux usées. Ce dispositif 5 comprend un moteur 6 solidaire d'un corps de pompe 7, dans la partie inférieure duquel est logé un rotor 8, muni de pales 9 et monté sur l'arbre d'entraînement 10 du moteur 6. De plus, le corps de pompe 7 est disposé au-dessus du moteur d'entraînement 6 et, avantageusement, l'ensemble moteur-pompe est agencé verticalement au-dessous de la sortie horizontale 4 du siphon 3. Pour cela, un raccord coudé 11 relie, avec étanchéité, la sortie 4 du siphon 3 à l'entrée 12 dudit corps de pompe 7. Une sortie latérale horizontale 13 est ménagée dans le corps de pompe 7, sortie à laquelle est raccordée une extrémité d'un conduit d'évacuation 14 des eaux usées. Ce conduit d'évacuation 14 est coudé et remonte verticalement pour être mis en communication, par son autre extrémité, avec la canalisation 15 du réseau.Referring to Figure 1, the sanitary appliance 1 for the forced evacuation of wastewater comprises a bowl 2 having, at its lower part, a siphon 3. As shown in Figure 1, the siphon 3 can be an integral part of the bowl 2 and be made, like the latter, ceramic, stoneware or the like. This siphon 3 has, at the rear of the bowl 2, a horizontal outlet 4 below which is arranged, according to the invention, a pumping and grinding device 5 for wastewater. This device 5 comprises a motor 6 integral with a pump body 7, in the lower part of which is housed a rotor 8, provided with blades 9 and mounted on the drive shaft 10 of the motor 6. In addition, the body pump 7 is arranged above the drive motor 6 and, advantageously, the motor-pump assembly is arranged vertically below the horizontal outlet 4 of the siphon 3. For this, an elbow fitting 11 connects, with sealing , the outlet 4 of the siphon 3 at the inlet 12 of said pump body 7. A horizontal lateral outlet 13 is formed in the pump body 7, outlet to which is connected one end of a discharge pipe 14 for waste water . This discharge duct 14 is bent and rises vertically to be placed in communication, by its other end, with the pipe 15 of the network.

Cet agencement du conduit d'évacuation 14, surélevé par rapport au corps de pompe 7, permet de maintenir dans la cuvette 2 une garde d'eau suffisante. Le niveau d'eau 16 dans la cuvette 2 et le siphon 3 est en effet déterminé par la hauteur du conduit d'évacuation 14. Par ailleurs, le siphon 3 garantit une garde d'eau minimale, indiquée par la référence 16a, évitant ainsi toute remontée d'odeurs.This arrangement of the discharge conduit 14, raised relative to the pump body 7, allows to maintain in the bowl 2 a sufficient guard of water. The water level 16 in the bowl 2 and the siphon 3 is in fact determined by the height of the discharge duct 14. Furthermore, the siphon 3 guarantees a minimum water guard, indicated by the reference 16a, thus avoiding any rise in odors.

Ainsi, comme déjà indiqué, l'agencement du dispositif 5 au-dessous de la sortie 4 du siphon 3, et du corps de pompe 7 au-dessus du moteur d'entraînement 6 assure une position idéale pour le rotor 8 qui est constamment immergé.Thus, as already indicated, the arrangement of the device 5 below the outlet 4 of the siphon 3, and of the pump body 7 above the drive motor 6 ensures a ideal position for rotor 8 which is constantly submerged.

On remarque sur la figure 1 que cet agencement du dispositif 5 sous la sortie 4 du siphon 3 est rendu possible grâce à la compacité dudit dispositif, et il permet également la vidange aisée du corps de pompe 7 et l'inspection commode du conduit d'évacuation 14 en cas d'obstruction de ce dernier par un objet jeté accidentellement dans la cuvette.Note in Figure 1 that this arrangement of the device 5 under the outlet 4 of the siphon 3 is made possible thanks to the compactness of said device, and it also allows easy emptying of the pump body 7 and convenient inspection of the conduit evacuation 14 in the event of obstruction of the latter by an object accidentally thrown into the bowl.

Par ailleurs, dans le fond du moteur 6 est ménagée une rainure 17 qui coopère avec une languette 18 faisant saillie de la base 19 du socle 20 de la cuvette 2, de façon à caler le dispositif de pompage et de broyage 5. Cette languette peut être la barrette reliant les deux parois du socle. Afin d'améliorer l'amortissement des bruits et des vibrations engendrés par le dispositif, une bande en matière élastique 21 est prévue entre la rainure 17 et la languette 18.Furthermore, in the bottom of the motor 6 is formed a groove 17 which cooperates with a tongue 18 projecting from the base 19 of the base 20 of the bowl 2, so as to wedge the pumping and grinding device 5. This tongue can be the bar connecting the two walls of the base. In order to improve the damping of noise and vibrations generated by the device, a strip of elastic material 21 is provided between the groove 17 and the tongue 18.

En outre, de façon usuelle, la cuvette 2 présente à sa partie supérieure une chambre 22 de distribution en eau de rinçage, dont la paroi arrière 23 est traversée par un conduit 24 d'amenée de cette eau de rinçage. Cette chambre 22 alimente une chambre annulaire 25 qui débouche par des orifices 26 à l'intérieur de la cuvette 2.In addition, in the usual way, the bowl 2 has at its upper part a chamber 22 for distributing rinse water, the rear wall 23 of which is traversed by a conduit 24 for supplying this rinse water. This chamber 22 feeds an annular chamber 25 which opens out through orifices 26 inside the bowl 2.

En se référant aux figures 2 à 5, la paroi arrière 23 est pourvue d'une ouverture 27 pour le raccordement du conduit 24 au moyen d'une bague souple 28. De plus, la géométrie de l'ouverture 27 est telle que, une fois le conduit 24 mis en place grâce à la bague 28, au moins un passage d'air 29 demeure entre le conduit 24 et le bord 30 de l'ouverture 27. Plus particulièrement, sur la figure 2, deux passages d'air 29 opposés, chacun en forme de croissant, sont prévus de part et d'autre d'un trou central 36 pour le conduit 24. Dans la variante de réalisation de la paroi arrière 23, montrée sur les figures 4 et 5, un seul passage d'air 29 est prévu, lequel débouche dans le plafond 35 de la chambre de distribution 22, et est relié à un trou central 36.Referring to Figures 2 to 5, the rear wall 23 is provided with an opening 27 for the connection of the conduit 24 by means of a flexible ring 28. In addition, the geometry of the opening 27 is such that, a once the duct 24 is put in place thanks to the ring 28, at least one air passage 29 remains between the duct 24 and the edge 30 of the opening 27. More particularly, in FIG. 2, two air passages 29 opposites, each in crescent-shaped, are provided on either side of a central hole 36 for the conduit 24. In the alternative embodiment of the rear wall 23, shown in Figures 4 and 5, a single air passage 29 is provided, which opens into the ceiling 35 of the distribution chamber 22, and is connected to a central hole 36.

Lesdits passages 29, d'une part, facilitent l'introduction de la bague 28 et ainsi la mise en place du conduit 24 et, d'autre part, constituent, après la fixation du conduit, des prises d'air, qui participent à éviter tout phénomène de siphonnage des eaux usées dans l'adduction d'eau en cas d'obstruction ou de débordement de la cuvette.Said passages 29, on the one hand, facilitate the introduction of the ring 28 and thus the establishment of the conduit 24 and, on the other hand, constitute, after the fixation of the conduit, air intakes, which participate in avoid any phenomenon of siphoning of waste water in the water supply in the event of obstruction or overflow of the bowl.

En se référant maintenant aux figures 6 et 7, l'appareil sanitaire 1 comprend un dispositif de commande sans contact 31 de son cycle de fonctionnement, pourvu par exemple d'une cellule photoélectrique 32 qui débouche sur une paroi latérale 33 de la partie supérieure arrière de l'appareil. Cette cellule photoélectrique 32 détecte la présence de la main 34 de l'utilisateur, ou de tout autre objet traversant son champ d'action, à une certaine distance de l'appareil sanitaire 1.Referring now to Figures 6 and 7, the sanitary appliance 1 comprises a contactless control device 31 for its operating cycle, for example provided with a photoelectric cell 32 which opens onto a side wall 33 of the rear upper part of the device. This photoelectric cell 32 detects the presence of the user's hand 34, or of any other object passing through its field of action, at a certain distance from the sanitary appliance 1.
