Description

La présente invention concerne un appareil à moteur, et à cuve à liquide munie de résistance chauffante.The present invention relates to an apparatus with a motor and a liquid tank provided with a heating resistance.

Dans un appareil à moteur, et à cuve à liquide munie d'une ou de plusieurs résistances chauffantes, tel qu'une machine à laver le linge ou la vaisselle, se pose habituellement le problème d'étanchéité de la cuve de l'appareil, et de bruit engendré par la ou les résistances chauffantes qui vibrent pendant son fonctionnement. En effet, dans un tel appareil, la résistance assurant le chauffage du liquide est souvent fixée sur la paroi latérale et près du fond de la cuve, de manière à avoir son corps chauffant se trouvant à l'intérieur de la cuve, et ses extrémités faisant saillie à travers cette paroi, vers l'extérieur de la cuve pour permettre les connexions d'alimentation électrique. Cette traversée de la paroi de la cuve par la résistance chauffante soulève le problème d'étanchéité de cette cuve. De nombreuses solutions connues ont été apportées à ce problème pour réaliser correctement à la fois la fixation de cette résistance chauffante et l'étanchéité de la cuve.In a motorized appliance, and with a liquid tank provided with one or more heating resistors, such as a washing machine for washing clothes or dishes, the problem of sealing the tank of the appliance is usually raised, and noise generated by the heating element (s) which vibrate during its operation. Indeed, in such an apparatus, the resistance ensuring the heating of the liquid is often fixed on the side wall and near the bottom of the tank, so as to have its heating body being inside the tank, and its ends protruding through this wall, towards the outside of the tank to allow the power supply connections. This crossing of the wall of the tank by the heating resistor raises the problem of sealing of this tank. Many known solutions have been made to this problem in order to correctly carry out both the fixing of this heating resistor and the sealing of the tank.

Par exemple, dans la publication CH-A-427 342 est décrite une fixation étanche de l'extrémité d'une résistance chauffante dans une ouverture de la paroi d'une cuve à liquide au moyen d'un joint élastique serré entre une coupelle et la tête d'un tirant.For example, in publication CH-A-427 342, a tight attachment of the end of a heating resistor is described in an opening in the wall of a liquid tank by means of an elastic seal tightened between a cup and the head of a drawing.

Dans la publication FR-A-2185 711 est mentionnée une résistance chauffante logée dans l'espace entre le tambour et la cuve de la partie inférieure d'une machine à laver le linge à ouverture frontale, cette résistance étant montrée, dans le dessin, fixée contre la paroi arrière de cette cuve.In publication FR-A-2185 711, a heating resistor housed in the space between the drum and the tub of the lower part of a washing machine with a front opening is mentioned, this resistance being shown in the drawing, fixed against the rear wall of this tank.

Cependant, en dehors de ce problème d'étanchéité, le moteur de l'appareil crée lors de son fonctionnement, des vibrations qui sont transmises à la cuve et la résistance chauffante et provoquent des chocs répétés entre cette résistance chauffante et le fond de la cuve. Ces chocs mécaniques engendrent un bruit désagréable. Pour éliminer ce bruit, une solution connue consiste à percer un ou plusieurs trous dans le fond la cuve de l'appareil pour monter un ou plusieurs dispositifs destinés à maintenir le corps de la résistance chauffante. Cette solution s'avère efficace dans la suppression du bruit engendré par la résistance chauffante mais augmente le risque de fuite de la cuve à travers le ou les trous de montage de ces dispositifs de maintien de cette résistance chauffante.However, apart from this sealing problem, the device motor creates, during its operation, vibrations which are transmitted to the tank and the heating resistance and cause repeated shocks between this heating resistance and the bottom of the tank. . These mechanical shocks generate an unpleasant noise. To eliminate this noise, a known solution consists in drilling one or more holes in the bottom of the tank of the device to mount one or more devices intended to hold the body of the heating resistor. This solution proves effective in suppressing the noise generated by the heating resistance but increases the risk of leakage from the tank through the mounting hole or holes of these devices for holding this heating resistance.

Une autre solution connue, décrite dans la publication FR-A-2 343 849, consiste à fixer par soudage dans une cuve, un organe de retenue qui assure un maintien de l'extrémité d'une résistance chauffante en saillie à l'intérieur de cette cuve. Cet organe de retenue est constitué par une pièce formée d'une succession de parties courbées en U dont les creux sont alternativement tournés vers le haut et vers le bas. Les parties de cet organe de retenue ayant leurs creux ouverts vers le haut sont soudées à la cuve et celles ayant leurs creux tournés vers le bas servent à appliquer la résistance chauffante contre la cuve. Les fonds des parties en U ayant leur creux tournés vers le bas sont munies de languettes élastiques qui assurent une application de cette résistance chauffante contre la cuve et permettent ainsi d'éviter leurs trépidations. Cette solution se révèle plus ou moins efficace dans la suppression du bruit engendré par la résistance chauffante quand l'extrémité de celle-ci est plus ou moins en contact avec ces languettes et la force élastique de ces languettes est plus ou moins importante. Pour obtenir un bon résultat, les tolérances de fabrication et de fixation de la résistance chauffante et de cet organe de retenue doivent être rigoureuses et serrées. Ces exigences dans la fabrication et la fixation de ces derniers augmentent désavantageusement le prix de revient de l'appareil.Another known solution, described in the publication FR-A-2 343 849, consists in fixing by welding in a tank, a retaining member which ensures that the end of a heating resistance protrudes inside of this tank. This retaining member is constituted by a part formed by a succession of curved U-shaped parts, the recesses of which are alternately turned upwards and downwards. The parts of this retaining member having their recesses open upwards are welded to the tank and those having their recesses facing down serve to apply the heating resistance against the tank. The bottoms of the U-shaped parts having their recesses facing down are provided with elastic tongues which ensure that this heating resistance is applied against the tank and thus make it possible to avoid their trepidation. This solution appears to be more or less effective in suppressing the noise generated by the heating resistor when the end of the latter is more or less in contact with these tongues and the elastic force of these tongues is more or less significant. To obtain a good result, the manufacturing and fixing tolerances of the heating resistor and this retaining member must be rigorous and tight. These requirements in the manufacture and fixing of the latter disadvantageously increase the cost price of the device.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser un appareil à moteur et à cuve à liquide munie d'une résistance chauffante qui n'engendre pas de bruit lors du fonctionnement de l'appareil et qui n'exige pour sa mise en place qu'un seul trou de fixation percé dans la paroi de la cuve, ce qui permet ainsi de réduire au minimum le risque de fuite de la cuve et/ou de supprimer les dispositifs de maintien ou de retenue de cette résistance chauffante contre la cuve.The aim of the present invention is to avoid these drawbacks, which makes it possible to produce an apparatus with a motor and a liquid tank provided with a heating resistor which does not generate noise during the operation of the apparatus and which does not require for its installation only one fixing hole drilled in the wall of the tank, which thus makes it possible to minimize the risk of leakage from the tank and / or to remove the devices for holding or retaining this heating resistance against the tank.

Selon l'invention, un appareil à moteur, et à cuve à liquide munie d'au moins une résistance chauffante montée à travers un trou de passage formé dans la paroi latérale de cette cuve pour être en saillie dans celle-ci et avoir des extrémités qui sortent de la cuve fixées d'une manière étanche au niveau de ce trou au moyen d'un dispositif à joint d'étanchéité, serré par un tirant et un écrou de serrage monté sur ce tirant, caractérisé en ce qu'il comprend un levier de position monté sur les extrémités de cette résistance en saillie vers l'extérieur de la cuve, produisant dans sa combinaison avec le joint d'étanchéité élastique de ce dispositif à joint un effet de serrage décentré donnant à ce joint une double fonction, celle d'assurer une étanchéité à la fixation de la résistance chauffante et celle d'assurer une ferme application de cette résistance chauffante contre le fond de la cuve, pour former entre cette cuve et la résistance un ensemble mécanique rigide.According to the invention, an apparatus with a motor and a liquid tank provided with at least one heating resistor mounted through a passage hole formed in the side wall of this tank to protrude therein and have ends which leave the tank fixed in a leaktight manner at this hole by means of a seal device, tightened by a tie rod and a clamping nut mounted on this tie rod, characterized in that it comprises a position lever mounted on the ends of this resistance projecting towards the outside of the tank, producing in its combination with the elastic seal of this seal device an off-center clamping effect giving this seal a double function, that to ensure a seal at the fixing of the heating resistance and to ensure a firm application of this heating resistance against the bottom of the tank, to form between this tank and the resistance a rigid mechanical assembly.

Selon l'invention, un appareil à moteur, et à cuve à liquide, munie de résistance chauffante, peut être une machine à laver le linge schématiquement illustrée dans la figure 1, ou une machine à laver la vaisselle non représentée, ou tout autre appareil comportant une cuve à liquide munie d'au moins une résistance chauffante, et fonctionnent sous l'action d'un moteur.According to the invention, an appliance with a motor and a liquid tank, provided with a heating resistor, can be a washing machine for the laundry schematically illustrated in FIG. 1, or a washing machine for the dishes not shown, or any other appliance. comprising a liquid tank provided with at least one heating resistance, and operate under the action of a motor.

L'appareil 1 représenté, comme un exemple, dans la figure 1, est une machine à laver le linge comprenant une cuve à liquide 2, une résistance chauffante 3 montée près du fond de cette cuve 2, un tambour à linge 4 et un moteur d'entraînement 5. La résistance chauffante 3 peut avoir une forme d'un serpentin illustré dans la figure 1 ou une forme d'une tige, d'une épingle ou toute autre forme, non représentées.The device 1 shown, as an example, in Figure 1, is a washing machine comprising a liquid tank 2, a heating resistor 3 mounted near the bottom of this tank 2, a washing drum 4 and a motor 5. The heating resistor 3 may have the shape of a coil illustrated in FIG. 1 or the shape of a rod, a pin or any other shape, not shown.

La résistance 3 est fixée sur la paroi latérale de la cuve 2 de manière que son corps chauffant se trouve à l'intérieur de cette cuve et ses extrémités permettant les connexions d'alimentation électrique soient saillantes vers l'extérieur de la cuve à travers une ouverture de passage 6 formée dans la paroi de cette cuve.The resistance 3 is fixed on the side wall of the tank 2 so that its heating body is inside this tank and its ends allowing the electrical supply connections are protruding towards the outside of the tank through a passage opening 6 formed in the wall of this tank.

Quand le moteur 5 tourne, ses vibrations sont transmises à l'ensemble de l'appareil 1 et en particulier à la cuve 2 et la résistance 3.When the motor 5 is running, its vibrations are transmitted to the entire apparatus 1 and in particular to the tank 2 and the resistor 3.

Dans un appareil connu partiellement et schématiquement représenté dans la figure 2, appareil du type de celui illustré à la figure 1, une résistance chauffante 7, s'étendant parallèlement au fond 8 d'une cuve 9, ayant d'une part ses extrémités fixées à la paroi latérale 10 de cette cuve, et d'autre part son corps fermement maintenu par un dispositif 18 monté dans le fond 8. Les extrémités de la résistance 7 sur lesquelles sont réalisées les connexions d'alimentation électrique, sont montées à travers une ouverture allongée 11 et maintenues étanches dans des trous 12, d'une coupelle allongée 13. La résistance 7 est fixée d'une manière étanche, à la paroi latérale 10 de la cuve, au moyen d'une part, d'un joint élastique 14 et d'une coupelle 13 appliqués contre la surface extérieure du bord de l'ouverture 11 de la cuve 9, et d'autre part, d'un fourreau élastique 15 et d'un tirant 16 serrés, à l'aide d'un écrou 17, contre la surface intérieure du bord de l'ouverture 11 de la cuve 9. Le dispositif 18 qui maintient le corps de la résistance 7 est constitué par une agrafe montée à travers un trou 19 percé dans le fond 8 de la cuve et fixée par un écrou 20. Un joint élastique 21 assure l'étanchéité du trou 19 de la cuve 9. Au cours du fonctionnement de l'appareil, les vibrations du moteur d'entraînement sont transmises à la cuve 9 et la résistance 7. L'agrafe 18 empêche la résistance 7 dans sa vibration de toucher le fond 8 de la cuve 8 et permet d'éliminer ainsi une source de bruit. On remarque cependant que la présence du trou 19 dans le fond 8 crée un risque supplémentaire de fuite de la cuve 9, s'ajoutant à celui créé par l'ouverture 11 formée dans la paroi latérale 10 de cette cuve.In a known device partially and schematically shown in Figure 2, device of the type illustrated in Figure 1, a heating resistor 7, extending parallel to the bottom 8 of a tank 9, having on the one hand its fixed ends to the side wall 10 of this tank, and on the other hand its body firmly held by a device 18 mounted in the bottom 8. The ends of the resistor 7 on which the electrical supply connections are made, are mounted through a elongated opening 11 and kept tight in holes 12, of an elongated cup 13. The resistor 7 is fixed in a leaktight manner to the side wall 10 of the tank, by means of, on the one hand, an elastic seal 14 and a cup 13 applied against the outer surface of the edge of the opening 11 of the tank 9, and on the other hand, an elastic sheath 15 and a tight tie 16, using a nut 17, against the inner surface of the edge of the opening 11 of the tank 9. The di spositif 18 which holds the body of the resistor 7 consists of a clip mounted through a hole 19 drilled in the bottom 8 of the tank and fixed by a nut 20. An elastic seal 21 seals the hole 19 of the tank 9. During the operation of the device, the vibrations of the drive motor are transmitted to the tank 9 and the resistance 7. The clip 18 prevents the resistance 7 in its vibration from touching the bottom 8 of the tank 8 and eliminates a source of noise. Note, however, that the presence of the hole 19 in the bottom 8 creates an additional risk of leakage from the tank 9, adding to that created by the opening 11 formed in the side wall 10 of this tank.

L'invention permet d'éliminer avantageusement ce risque supplémentaire souvent rencontré dans les appareils connus.The invention advantageously eliminates this additional risk often encountered in known devices.

Selon l'invention, l'appareil comprend une cuve à liquide et une résistance chauffante dont le corps est forcé de prendre une position plus ou moins inclinée pour être fermement et librement appliqué contre le fond de la cuve, lequel constitue un appui permanent, et les extrémités destinées aux connexions d'alimentation électrique sont hermétiquement fixées dans une ouverture de la paroi latérale de la cuve.According to the invention, the apparatus comprises a liquid tank and a heating resistor whose body is forced to assume a more or less inclined position so as to be firmly and freely applied against the bottom of the tank, which constitutes a permanent support, and the ends for the power supply connections are hermetically fixed in an opening in the side wall of the tank.

Dans l'exemple partiellement et schématiquement illustré à la figure 3, l'appareil comprend, une cuve à liquide 22 et une résistance chauffante ayant la forme d'un serpentin 23. L'extrémité de la résistance chauffante 23 sont fixées dans une ouverture 24 de la paroi latérale de la cuve 22, au moyen par exemple, d'un joint élastique 25 serré entre une coupelle 26 et la tête d'un tirant 27, les extrémités de la résistance chauffante 23 qui traversent la coupelle 26 étant rendues hermétiques et rigidement solidaires de cette coupelle 26 par soudage, sertissage ou toute autre technique connue. Ces éléments de fixation, à savoir la coupelle 26, le joint 25 et le tirant 27 coopèrent, avec un levier de position 28 et le fond 29 de la cuve 22, dans la mise en place de la résistance 23 de manière à ne pas exiger, comme dans un dispositif de fixation de type classique (figure 2), un perçage d'un trou 19 dans le fond de la cuve 22.In the example partially and schematically illustrated in Figure 3, the apparatus comprises, a liquid tank 22 and a heating resistor in the form of a coil 23. The end of the heating resistor 23 are fixed in an opening 24 from the side wall of the tank 22, for example by means of an elastic seal 25 clamped between a cup 26 and the head of a tie rod 27, the ends of the heating resistor 23 which pass through the cup 26 being made hermetic and rigidly secured to this cup 26 by welding, crimping or any other known technique. These fastening elements, namely the cup 26, the seal 25 and the tie rod 27 cooperate, with a position lever 28 and the bottom 29 of the tank 22, in the establishment of the resistor 23 so as not to require , as in a fixing device of conventional type (FIG. 2), drilling a hole 19 in the bottom of the tank 22.

Le levier de position 28 est constitué par une pièce en U pourvue de branches parallèles de longueurs inégales -30 et 31, et dans le fond, d'un trou 32 pour le passage de la tige du tirant 27. Le trou 32 a de préférence, un diamètre nettement supérieur à celui de la tige de ce tirant pour donner à cette dernière, une grande liberté de mouvement d'orientation.The position lever 28 is constituted by a U-shaped part provided with parallel branches of unequal lengths -30 and 31, and in the bottom, with a hole 32 for the passage of the rod of the tie rod 27. The hole 32 preferably has , a diameter markedly greater than that of the rod of this tie rod to give the latter a great freedom of orientation movement.

Le levier 28 est monté sur la tige du tirant 27, avec sa branche courte 31 appliquée sur la moitié supérieure de la coupelle 26 par rapport à ce tirant 27, et sa branche longue 30 reposant sur la paroi de la cuve 22 qui se trouve en dessous de ce tirant. Le levier 28 est serré contre la cuve 22 et la coupelle 26 par un écrou 33 monté sur la tige du tirant 27. Plus l'écrou 33 est tourné dans le sens de serrage, plus la branche courte 31 du levier 28 pousse sur la moitié supérieure de la coupelle 26, et déforme la partie du joint élastique 25 sous- jacent. C'est l'effet d'un serrage décentré qui force la coupelle 26 à se mettre en position inclinée. La moitié supérieure de la coupelle 26 est ainsi plus rapprochée de la paroi de la cuve 22 que la partie inférieure de cette coupelle. La coupelle 26 qui est rigidement solidaire de la résistance 23 incline par conséquent cette dernière vers la cuve 22 et l'applique fermement contre le fond de cette dernière, ce fond constituant un appui permanent à cette résistance. La résistance chauffante 23 et la cuve 22 forment alors un ensemble mécanique rigide et la résistance chauffante 23 est forcée de vibrer en bloc avec la cuve 22 lors du fonctionnement du moteur non représenté de l'appareil. L'inconvénient du bruit gênant engendré par des chocs mécaniques répétés entre la résistance chauffante et la cuve en vibration, est ainsi évité.The lever 28 is mounted on the rod of the tie rod 27, with its short branch 31 applied to the upper half of the cup 26 relative to this tie rod 27, and its long branch 30 resting on the wall of the tank 22 which is located in below this drawing. The lever 28 is tightened against the tank 22 and the cup 26 by a nut 33 mounted on the rod of the tie rod 27. The more the nut 33 is turned in the direction tightening, the more the short branch 31 of the lever 28 pushes on the upper half of the cup 26, and deforms the part of the elastic seal 25 underlying. It is the effect of an off-center tightening which forces the cup 26 to move into an inclined position. The upper half of the cup 26 is thus closer to the wall of the tank 22 than the lower part of this cup. The cup 26 which is rigidly secured to the resistor 23 consequently inclines the latter towards the tank 22 and applies it firmly against the bottom of the latter, this bottom constituting a permanent support for this resistor. The heating resistor 23 and the tank 22 then form a rigid mechanical assembly and the heating resistor 23 is forced to vibrate in block with the tank 22 during the operation of the not shown motor of the device. The inconvenience of the annoying noise generated by repeated mechanical shocks between the heating resistor and the vibrating tank is thus avoided.

Dans une première variante de réalisation de l'invention, illustrée dans la figure 4, le levier de position est constitué par une pièce L 34 dont l'une des extrémités est munie d'un trou 35 pour un passage avec jeu de la tige du tirant coopérant 27, et l'autre extrémité porte une vis de réglage d'écartement 36. Le levier 34 est monté entre un écrou de serrage 33 et la coupelle 26, avec son extrémité à vis de réglage se reposant sur la paroi de la cuve se trouvant en dessous du tirant 27 et son autre extrémité s'appuyant sur la moitié supérieure de cette coupelle par rapport à ce tirant. Pour un serrage donné de l'écrou 33, plus l'extrémité du levier 34 portant la vis 36 est écartée de la cuve 22 par cette vis 36, plus sa deuxième extrémité munie du trou de passage 35 pousse sur la moitié supérieure de la coupelle 26 par rapport à ce tirant 27 et la rapproche davantage de la paroi de la cuve que sa moitié inférieure. La coupelle 26, rigidement solidaire de la résistance chauffante 23, incline cette résistance vers la cuve et l'applique fermement contre le fond 29 de celle-ci. Comme dans l'exemple de la figure 3, la résistance 23 forme ainsi la cuve 22 un ensemble mécanique rigide. Cette liaison mécanique entre la résistance 23 et le fond 29 de la cuve, peut être renforcée par des bossages 37 formés dans ce fond 29, de part et d'autre du trajet tracé par le corps de cette résistance. En effet, ces bossages 37 augmentent non seulement la rigidité du fond 29 de la cuve 22 mais constituent également des butées empêchant tous mouvements latéraux éventuels de la résistance chauffante 23.In a first alternative embodiment of the invention, illustrated in FIG. 4, the position lever consists of a part L 34, one of the ends of which is provided with a hole 35 for passage with clearance of the rod of the cooperating tie 27, and the other end carries a spacing adjustment screw 36. The lever 34 is mounted between a tightening nut 33 and the cup 26, with its adjusting screw end resting on the wall of the tank being located below the tie rod 27 and its other end resting on the upper half of this cup relative to this tie rod. For a given tightening of the nut 33, the more the end of the lever 34 carrying the screw 36 is moved away from the tank 22 by this screw 36, the more its second end provided with the through hole 35 pushes on the upper half of the cup 26 relative to this tie rod 27 and brings it closer to the wall of the tank than its lower half. The cup 26, rigidly secured to the heating resistor 23, inclines this resistance towards the tank and applies it firmly against the bottom 29 of the latter. As in the example in FIG. 3, the resistor 23 thus forms the tank 22 a rigid mechanical assembly. This mechanical connection between the resistor 23 and the bottom 29 of the tank, can be reinforced by bosses 37 formed in this bottom 29, on either side of the path traced by the body of this resistor. In fact, these bosses 37 not only increase the rigidity of the bottom 29 of the tank 22 but also constitute stops preventing any possible lateral movements of the heating resistance 23.

Dans une deuxième variante de réalisation de l'invention, illustrée dans la figure 5, le levier de position est constitué par une patte radiale plate 28 de la coupelle 26, qui prolonge le plan du fond de la coupelle 26. Cette patte 38 est munie à son extrémité d'une vis de réglage d'écartement 39. La coupelle 26 avec sa patte 38 est serrée contre le joint élastique 25 par un écrou 40, vissant sur la tige du tirant 27. Plus l'extrémité de la patte 38 portant la vis 39 est écartée de la paroi de la cuve 22, qui se trouve en dessous du tirant 27, plus la moitié supérieure de la coupelle 26 diamétralement opposée à cette patte 38 est rapprochée de la paroi de la cuve, par rapport à sa moitié inférieure. La coupelle 26 qui est rigidement solidaire de la résistance chauffante 23 incline cette résistance vers la cuve et l'applique fermement contre le fond 29 de cette dernière. La résistance chauffante 23 forme alors avec la cuve 22 un ensemble mécanique rigide qui vibre en bloc durant le fonctionnement du moteur non représenté de l'appareil.In a second alternative embodiment of the invention, illustrated in FIG. 5, the position lever is constituted by a flat radial tab 28 of the cup 26, which extends the plane of the bottom of the cup 26. This tab 38 is provided at its end with a spacing adjustment screw 39. The cup 26 with its tab 38 is tightened against the elastic joint 25 by a nut 40, screwing onto the rod of the tie rod 27. The end of the tab 38 bearing the screw 39 is spaced from the wall of the tank 22, which is located below the tie rod 27, plus the upper half of the cup 26 diametrically opposite to this lug 38 is brought closer to the wall of the tank, relative to its half lower. The cup 26 which is rigidly secured to the heating resistance 23 inclines this resistance towards the tank and applies it firmly against the bottom 29 of the latter. The heating resistor 23 then forms with the tank 22 a rigid mechanical assembly which vibrates as a unit during the operation of the not shown motor of the device.

Dans une troisième variante de réalisation de l'invention illustrée dans la figure 6, le levier de position est constitué par un ergot longitudinal 41 de la coupelle 26, qui prolonge son bord. La coupelle 26 avec son ergot longitudinal 41 est serrée contre le joint élastique 25 par l'écrou 40 monté sur la tige du tirant 27. Plus le serrage de l'écrou 40 est poussé, plus la moitié supérieure de la coupelle 26 diamétralement opposée à l'ergot 41 est rapprochée de la paroi de la cuve, l'ergot 41 étant en butée contre la paroi de cette cuve qui se trouve en dessous du tirant 27. La coupelle 26 qui est rigidement solidaire de la résistance 23, incline cette résistance vers la cuve 22 et l'applique fermement contre le fond 29 de cette dernière. La résistance chauffante 23 forme alors avec la cuve un ensemble mécanique rigide qui vibre en bloc, lors du fonctionnement du moteur non représenté de l'appareil.In a third alternative embodiment of the invention illustrated in FIG. 6, the position lever consists of a longitudinal lug 41 of the cup 26, which extends its edge. The cup 26 with its longitudinal lug 41 is tightened against the elastic seal 25 by the nut 40 mounted on the rod of the tie rod 27. The more the tightening of the nut 40, the more the upper half of the cup 26 diametrically opposite to the lug 41 is brought closer to the wall of the tank, the lug 41 being in abutment against the wall of this tank which is below the tie rod 27. The cup 26 which is rigidly secured to the resistor 23, inclines this resistor towards the tank 22 and applies it firmly against the bottom 29 of the latter. The heating resistor 23 then forms with the tank a rigid mechanical assembly which vibrates as a unit, during the operation of the not shown motor of the device.

Dans les variantes de réalisation illustrées dans les figures 5 et 6, les bossages 37 formés dans le fond 29 de la cuve assurent également les mêmes fonctions que celles indiquées dans la variante représentée dans la figure 4.In the variant embodiments illustrated in FIGS. 5 and 6, the bosses 37 formed in the bottom 29 of the tank also provide the same functions as those indicated in the variant shown in FIG. 4.

L'appareil réalisé selon l'invention a ainsi une structure simple et économique et comporte un risque minimum de fuite et de bruit.The apparatus produced according to the invention thus has a simple and economical structure and comprises a minimum risk of leakage and noise.
