Pour faire fonctionner un tel appareil, il est nécessaire d'amener une quantité suffisante d'eau To operate such a device, it is necessary to bring a sufficient amount of water

Il est ainsi connu de disposer des éléments de chauffage, par exemple des serpentins de chauffage, à l'intérieur des appareils. Dans ce cas sont désavantageux, non seulement le coût de construction, celui de la technique de montage, et la considération d'éventuelles réparations, mais aussi le contact direct des éléments de chauffage avec l'eau à chauffer, ce qui, en particulier, mène à des restrictions notables de la durée de vie, dans le cas d'eau à forte teneur en calcaire ou rend nécessaire l'adoption d'autres It is thus known to have heating elements, for example heating coils, inside the devices. In this case are disadvantageous not only the cost of construction, that of the assembly technique, and the consideration of possible repairs, but also the direct contact of the heating elements with the water to be heated, which, in particular, leads to significant service life restrictions in the case of water with a high lime content or necessitates the adoption of other
dispositions constructives.constructive provisions.
Il est en outre connu de brancher, en amont des appareils cités cidessus, un chauffe-eau ou un réchauffeur séparé à circulation forcée, dans lesquels l'eau est chauffée à la température nécessaire. De telles unités supplémentaires demandent cependant de la place supplémentaire, faisant que les appareils, soit présentent un grand encombrement, soit disposent d'un volume utile réduit en conséquence, et sont en partie It is also known to connect, upstream of the devices mentioned above, a separate water heater or heater with forced circulation, in which the water is heated to the necessary temperature. However, such additional units require additional space, so that the devices either have a large footprint or have a correspondingly reduced useful volume, and are partly

Ce problème est résolu, pour une pompe du ty- This problem is solved, for a pump of the ty-
pe précité, en ce que le moyen permettant le chauffage du liquide présente un dispositif de chauffage, disposé sur la face extérieure du carter de la pompe, et une plaque de distribution de chaleur, disposée entre la pe above, in that the means for heating the liquid has a heating device, arranged on the outer face of the pump housing, and a heat distribution plate, disposed between the
paroi de carter et le dispositif de chauffage. housing wall and heater.
Du fait de l'agencement tant du dispositif de chauffage que de celui de la plaque de distribution de chaleur à l'extérieur du carter de pompe proprement dit et sans apporter de modification à celui-ci, on peut réaliser, selon l'invention, une pompe classique n'ayant qu'un faible coût de construction. La chaleur est amenée par le dispositif de chauffage à la face extérieure du carter de pompe et est répartie sur la paroi de carter, pratiquement régulièrement, au moyen de la plaque de distribution de chaleur, disposée entre le dispositif de chauffage et la paroi du carter de pompe. Aucun contact direct entre le dispositif de chauffage et le liquide à chauffer ne peut alors exister. Selon un mode de réalisation préféré, la plaque de distribution de chaleur est disposée parallèlement à la paroi extérieure de carter et en appui sur celle-ci. Elle assure une surface de contact maximale possible entre la plaque de distribution de chaleur et la paroi de carter et permet en conséquence Due to the arrangement of both the heating device and that of the heat distribution plate outside the pump casing proper and without making any modification thereto, it is possible, according to the invention, a conventional pump having only a low construction cost. The heat is brought by the heating device to the external face of the pump casing and is distributed over the casing wall, almost regularly, by means of the heat distribution plate, arranged between the heating device and the casing wall. pump. No direct contact between the heating device and the liquid to be heated can then exist. According to a preferred embodiment, the heat distribution plate is arranged parallel to the outer casing wall and resting thereon. It ensures the maximum possible contact surface between the heat distribution plate and the housing wall and consequently allows
un bon transfert de chaleur.good heat transfer.
Il est alors avantageux que la plaque de distribution de chaleur soit adaptée au contour extérieur du carter de pompe et si des zones planes peuvent y être conformées, également pratiquement plane, c'est-à- dire dans une forme particulièrement simple à fabriquer, étant en outre avantageux que la plaque de distribution de chaleur soit reliée à la It is then advantageous for the heat distribution plate to be adapted to the external contour of the pump housing and if planar zones can be formed therein, also practically planar, that is to say in a form which is particularly simple to manufacture, being further advantageous that the heat distribution plate is connected to the

un bon transfert de chaleur entre les deux éléments. good heat transfer between the two elements.
Selon un mode de réalisation particulièrement avantageux, la plaque de distribution de chaleur est réalisée en aluminium, faisant que l'on peut assurer une distribution de chaleur rapide et régulière dans la plaque et une très bonne transmission de la chaleur du According to a particularly advantageous embodiment, the heat distribution plate is made of aluminum, making it possible to ensure rapid and regular heat distribution in the plate and very good heat transfer from the

L'enveloppe du corps chauffant, en particulier un corps chauffant tubulaire, est avantageusement réalisée The envelope of the heating body, in particular a tubular heating body, is advantageously made

Il est alors avantageux que le carter de pompe soit en acier inoxydable et qu'ainsi il puisse être fabriqué de façon classique et que, de manière correspondante, il soit insensible aux dépôts ou incrustations ou aux effets chimiques provoqués par les It is then advantageous that the pump housing is made of stainless steel and that thus it can be manufactured in a conventional manner and that, correspondingly, it is insensitive to deposits or incrustations or to the chemical effects caused by the

Dans le dessin: 5. la figure 1 représente une vue de l'aval de la pompe, en coupe; la figure 2 représente le carter de pompe vu en referring to the embodiments shown in the drawing, given by way of example. In the drawing: 5. Figure 1 shows a downstream view of the pump, in section; Figure 2 shows the pump housing seen in
perspective et partiellement en coupe. perspective and partially in section.
La pompe 1, représentée sur la figure 1, est constituée d'un carter en acier inoxydable 2 réalisé en deux parties, auxquelles le liquide à faire circuler est amené par une entrée de pompe 3 et évacué par une sortie de pompe 4. A l'intérieur du carter 2 est disposé un rotor de pompe 5 entraîné par un arbre de pompe 6 entraîné par un moteur et monté sur palier au centre du socle du carter de pompe. La pompe 1 est remplie, en fonctionnement, de manière que se constitue un niveau de liquide 7. Dans le volume de la pompe 1 rempli de liquide, est conformée sur la face extérieure du carter 5 en acier inoxydable une plaque périphérique en aluminium mise en appui sur le carter en acier inoxydable et faisant office de plaque de distribution de chaleur 8. Le carter 2 est réalisé dans cette zone de la pompe 1 sous une forme tronconique et se trouve mis en contact plat par une surface aussi grande que possible, avec la plaque de distribution de chaleur 8 adjacente, conformée en enveloppe tronconique. Pour éviter tout soulèvement de la plaque de distribution de chaleur 8 par rapport au carter, du fait de la différence de dilatation thermique entre les deux matériaux et d'une plus mauvaise transmission de chaleur consécutive entre ces deux éléments, le carter 2 est brasé à la plaque de distribution de chaleur 8. Sur la face, opposée au carter 2, de la plaque de distribution de chaleur 8, est monté un corps chauffant tubulaire 9. Le corps chauffant tubulaire 9 est disposé de façon notablement concentrique par The pump 1, shown in FIG. 1, consists of a stainless steel casing 2 made in two parts, to which the liquid to be circulated is brought by a pump inlet 3 and evacuated by a pump outlet 4. A l inside the casing 2 is arranged a pump rotor 5 driven by a pump shaft 6 driven by a motor and mounted on a bearing in the center of the base of the pump casing. The pump 1 is filled, in operation, so that a liquid level is formed 7. In the volume of the pump 1 filled with liquid, is formed on the outer face of the casing 5 in stainless steel a peripheral aluminum plate placed support on the stainless steel casing and acting as a heat distribution plate 8. The casing 2 is produced in this zone of the pump 1 in a frustoconical shape and is placed in flat contact by as large a surface as possible, with the adjacent heat distribution plate 8, shaped as a frustoconical envelope. To avoid any lifting of the heat distribution plate 8 relative to the casing, due to the difference in thermal expansion between the two materials and a worse consecutive heat transmission between these two elements, the casing 2 is brazed to the heat distribution plate 8. On the face, opposite the casing 2, of the heat distribution plate 8, is mounted a tubular heating body 9. The tubular heating body 9 is arranged in a substantially concentric manner by
27941932794193
rapport à l'arbre de pompe et également disposé notablement centralement sur la plaque de distribution de chaleur 8. La chaleur nécessaire au chauffage du liquide, de préférence de l'eau, est amenée par le corps chauffant tubulaire 9. Le corps chauffant tubulaire est placé en appui direct contre la plaque de distribution de chaleur 8 et fournit, de manière correspondante, à celui-ci la chaleur. Du fait de la très bonne conductivité thermique de la plaque de distribution de chaleur 8 réalisée en aluminium, cette chaleur est transmise uniformément sur la zone, en appui sur la plaque de distribution de chaleur 8, du carter 2 de la pompe 1 et, de là, de nouveau au liquide se trouvant dans cette zone de la pompe ayant atteint le niveau de liquide 7. Des éléments de régulation, qui ne sont cependant pas représentés sur la figure 1, sont prévus pour réguler l'apport de chaleur provenant du corps chauffant tubulaire 9. Les éléments de régulation non représentés peuvent être disposés sur la plaque de distribution de chaleur 8, en raison de la très bonne relative to the pump shaft and also arranged notably centrally on the heat distribution plate 8. The heat necessary for heating the liquid, preferably water, is supplied by the tubular heating body 9. The tubular heating body is placed in direct abutment against the heat distribution plate 8 and supplies, in a corresponding manner, the heat thereof. Due to the very good thermal conductivity of the heat distribution plate 8 made of aluminum, this heat is transmitted uniformly over the area, bearing on the heat distribution plate 8, from the casing 2 of the pump 1 and, from there, again to the liquid being in this zone of the pump having reached the level of liquid 7. Regulating elements, which are not however shown in FIG. 1, are provided to regulate the supply of heat coming from the body tubular heater 9. The control elements not shown can be arranged on the heat distribution plate 8, due to the very good
conductivité thermique de celle-ci. thermal conductivity thereof.
L'enveloppe de carter 10 représentée partiellement en coupe sur la figure 2, et réalisée en acier inoxydable avec une entrée de pompe non représentée et la sortie de pompe 4, présente, en analogie avec la forme de réalisation de la figure 1, une plaque de distribution de chaleur 8 dans la zone de la couverture supérieure de l'enveloppe de carter 10, plaque disposée en forme d'anneau autour de la sortie de pompe 4 et appuyant à plat sur le couvercle 11, également plat, du carter 2. Un corps chauffant tubulaire 9, réalisé de manière analogue à celui de la figure 1, est disposé également concentriquement à la sortie de pompe 4, sur la plaque de distribution de chaleur 8. Le transfert du liquide s'effectue au moyen d'un équipement de pompe, analogue à celui représenté The casing casing 10 shown partially in section in FIG. 2, and made of stainless steel with a pump inlet not shown and the pump outlet 4, presents, in analogy with the embodiment of FIG. 1, a plate heat distribution 8 in the area of the upper cover of the casing casing 10, plate arranged in the form of a ring around the pump outlet 4 and pressing flat on the cover 11, also flat, of the casing 2. A tubular heating body 9, produced analogously to that of FIG. 1, is also arranged concentrically at the pump outlet 4, on the heat distribution plate 8. The transfer of the liquid is carried out by means of equipment. pump, similar to that shown
