On a montré en figures 1, 2 et 3 un dispositif de chauffage et de régulation 1 comprenant une embase 2 solidaire d'une résistance de chauffage 3 et d'une sonde de régulation 4 et un boîtier isolant 5 venant se fixer sur ladite embase.We have shown in figures 1 , 2 and 3 a heating and regulating device 1 comprising a base 2 integral with a heating resistor 3 and a regulating probe 4 and an insulating casing 5 being fixed on said base.

L'embase 2 est réalisée dans une pièce en laiton, ou dans un autre matériau conducteur de la chaleur, se prolongeant du coté de la résistance de chauffage 3 et de la sonde de régulation 4 par des moyens de fixation 6 permettant la retenue étanche du dispositif de chauffage et de régulation 1 dans le fond d'une cuve 7 d'un ballon d'eau chaude 8 d'un chauffe-eau.The base 2 is made in a piece of brass, or in another heat-conducting material, extending on the side of the heating resistor 3 and the regulating probe 4 by means of fixing 6 allowing the impervious containment of the heating and regulating device 1 in the bottom of a tank 7 of a hot water tank 8 of a water heater.

Les moyens de fixation 6 sont constitués d'une couronne circulaire 9 prolongeant le fond 15 de l'embase 2 conductrice de la chaleur et comportant sur sa face externe un filetage 10 destiné à coopérer avec un profil complémentaire aménagé dans le fond de la cuve 7 du ballon d'eau chaude 8.The fastening means 6 consist of a circular ring 9 extending the bottom 15 of the base 2 conducts heat and having on its outer face a thread 10 for cooperating with a complementary profile arranged in the bottom of the tank 7 hot water tank 8.

L'étanchéité est assurée, lors de la fixation du dispositif de chauffage et de régulation 1 dans le fond de la cuve 7 du ballon d'eau chaude 8, par la mise en place d'un joint 43 autour de la couronne circulaire 9 afin que ce dernier vienne en appui serré entre le fond de ladite cuve 7 et le bord périphérique 44 de l'embase 2 conductrice de la chaleur (figure 6).Sealing is ensured, during the fixing of the heating and regulating device 1 in the bottom of the tank 7 of the hot water tank 8, by the establishment of a seal 43 around the circular ring 9 so that the latter comes to bear tightly between the bottom of said tank 7 and the peripheral edge 44 of the base 2 conducts heat ( figure 6 ).

La couronne circulaire 9 comprend dans sa partie interne des logements cylindriques creux 11, 12 et 13 traversant de part en part l'embase 2 conductrice de la chaleur du dispositif de chauffage et de régulation 1.The circular ring 9 comprises, in its internal part, hollow cylindrical housings 11, 12 and 13 passing right through the base 2 which conducts the heat of the heating and regulating device 1.

La résistance de chauffage 3 est constituée, à la manière connue en soi, d'un tube creux, présentant un profil particulier et coudé, réalisé dans un matériau conducteur comportant dans sa partie interne une résistance électrique pourvue à chaque extrémité dudit tube de bornes de connexion 14.The heating resistor 3 is constituted, in the manner known per se, of a hollow tube, having a particular and bent profile, made of a conductive material having in its internal part an electrical resistance provided at each end of said terminal tube. connection 14.

Chaque extrémité de la résistance électrique 3 est introduite et fixée, par exemple par brasure, dans les logements cylindriques correspondants 11, 12 de l'embase 2 conductrice de la chaleur pour traverser cette dernière de manière étanche afin que les bornes de connexions 14 soient placées au-dessus du fond 15 de ladite embase et à l'opposé des moyens de fixation 6.Each end of the electrical resistance 3 is introduced and fixed, for example by brazing, into the corresponding cylindrical housings 11, 12 of the heat conducting base 2 to pass therethrough in a sealed manner so that the connection terminals 14 are placed above the bottom 15 of said base and opposite the fixing means 6.

Les bornes de connexion 14 de la résistance électrique 3 sont solidaires chacune d'un écrou 21 coopérant avec des vis 22 pour permettre la retenue du boîtier isolant 5 sur l'embase 2 conductrice de la chaleur.The connection terminals 14 of the electrical resistance 3 are each integral with a nut 21 cooperating with screws 22 to allow the retention of the insulating housing 5 on the base 2 of the heat conducting.

La sonde de régulation 4 est constituée, à la manière connue, d'un tube borgne dans lequel est montée une tige axiale ou tige invar 16 à faible coefficient de dilatation.The control probe 4 consists, in the known manner, of a blind tube in which is mounted an axial rod or invar rod 16 with a low coefficient of expansion.

La sonde de régulation 4 est introduite et fixée, par exemple par brasure, dans le logement cylindrique 13 de l'embase 2 conductrice de la chaleur pour traverser cette dernière de manière étanche afin que l'une des extrémités de la tige axiale ou tige invar 16 soit placée au-dessus du fond 15 de ladite embase et à l'opposé des moyens de fixation 6.The regulation probe 4 is introduced and fixed, for example by brazing, in the cylindrical housing 13 of the heat conducting base 2 to pass therethrough in a sealed manner so that one of the ends of the axial rod or invar rod 16 is placed above the bottom 15 of said base and opposite the fixing means 6.

L'extrémité de la tige invar 16 débouchant au-dessus du fond 15 de l'embase 2 conductrice de la chaleur coopère par l'intermédiaire d'un écrou 19 avec un levier isolant 20 permettant d'actionner un rupteur électrique assurant le pilotage de la résistance électrique 3 et donc de la régulation de la température de l'eau à l'intérieur du ballon d'eau chaude 8.The end of the invar rod 16 opening above the bottom 15 of the base 2 conducts heat cooperates via a nut 19 with a lever insulator 20 for actuating an electrical switch controlling the electrical resistance 3 and therefore the regulation of the water temperature inside the hot water tank 8.

Le levier isolant 20 est actionné par les mouvements de la tige d'invar 16 disposée à l'intérieur du tube de la sonde de régulation 4 qui se dilate sous l'effet de la température ou de la chaleur.The insulating lever 20 is actuated by the movements of the invar rod 16 disposed inside the tube of the regulating probe 4 which expands under the effect of temperature or heat.

L'écrou 19 permet d'une part de lier le levier isolant 20 avec l'extrémité libre de la tige d'invar 16 et d'autre part d'assurer le réglage de la température de régulation.The nut 19 makes it possible on the one hand to link the insulating lever 20 with the free end of the invar rod 16 and, on the other hand, to regulate the control temperature.

L'écrou 19 présente une surface externe dentelée de manière à coopérer avec un organe de réglage de la température 42 disposé à l'extérieur et au-dessus du boîtier isolant 5.The nut 19 has an outer surface serrated to cooperate with a temperature adjusting member 42 disposed outside and above the insulating housing 5.

L'embase 2 conductrice de la chaleur comporte, à l'opposé de ses moyens de fixation 6 et dans son fond 15, une empreinte circulaire 17 destinée à recevoir un disque bimétallique 18 qui permet d'actionner un coupe-circuit thermique de sécurité en cas d'élévation excessive de la température de l'eau contenue à l'intérieur de la cuve 7 du ballon d'eau chaude 8 .The heat conducting base 2 comprises, opposite its fastening means 6 and in its bottom 15, a circular imprint 17 intended to receive a bimetallic disc 18 which makes it possible to actuate a safety thermal cut-out in case of excessive rise in the temperature of the water contained inside the tank 7 of the hot water tank 8.

Le disque bimétallique 18 peut être, par exemple, remplacé par un dispositif à mémoire de forme tel que décrit dans le brevet FR 2 870 985 appartenant au demandeur.The bimetallic disc 18 can be, for example, replaced by a shape memory device as described in the patent FR 2,870,985 owned by the applicant.

En effet, l'embase 2 assure, du fait de la matière utilisée, un excellent transfert de chaleur entre l'eau contenue à l'intérieur de la cuve 7 du ballon d'eau chaude 8 et le coupe-circuit thermique de sécurité.Indeed, the base 2 ensures, because of the material used, an excellent heat transfer between the water contained inside the tank 7 of the hot water tank 8 and the safety circuit breaker.

On a montré en figure 4 et 5 l'embase 2 conductrice de la chaleur recevant sur sa face extérieure le boîtier isolant 5 dans lequel est monté et porté l'ensemble des éléments de connexion électriques et de sécurité du dispositif de chauffage et de régulation 1.We have shown in figure 4 and 5 the heat conducting base 2 receiving on its outer face the insulating housing 5 in which is mounted and carried all the electrical and safety connection elements of the heating and regulating device 1.

Le boîtier 5 est réalisé dans un matériau plastique ou autre ayant des caractéristiques isolantes et comportant des agencements permettant de recevoir et de guider tous les éléments de connexion électriques et de sécurité de manière que ces derniers ne soient jamais en contact direct avec l'embase 2 conductrice de la chaleur du dispositif de chauffage et de régulation 1.The housing 5 is made of a plastic material or other having insulating characteristics and having arrangements for receiving and guiding all the electrical and safety connection elements so that the latter are never in direct contact with the base 2 conductor of the heat of the heating and regulating device 1.

La connexion électrique au réseau d'alimentation du dispositif de chauffage et de régulation 1 suivant la présente invention se fait au moyen de pièces conductrices 23a, 23b qui sont réalisées dans un matériau élastique permettant une connexion rapide, sans outil et par pincement des fils de connexion.The electrical connection to the power supply of the heating and control device 1 according to the present invention is effected by means of conductive parts 23 a, 23 b that are made of an elastic material enabling a fast connection without tools and by pinching connection wires.

Les pièces conductrices 23a, 23b sont fixées au boîtier isolant 5 par sertissage et sont actionnées, pour passer d'une position d'ouverture à une position de fermeture, par l'installateur par l'intermédiaire de leviers isolants 24a, 24b guidés en pivotement dans ledit boîtier.The conductive parts 23 a, 23 b are fixed to the insulating housing by crimping and 5 are actuated to move from an open position to a closed position by the installer via insulating levers 24 a, 24 b pivotally guided in said housing.

Les pièces conductrices 23a, 23b comportent chacune une lame rigide 25a, 25b pourvue à son extrémité libre d'un contact 26a, 26b.The conductive parts 23 a, 23 b each comprise a rigid blade 25 a, 25 b provided at its free end a contact 26 a, 26 b.

Les pièces conductrices 23a, 23b assurent respectivement la connexion électrique (phase et neutre) du réseau d'alimentation, tandis que les lames rigides 25a, 25b coopèrent chacune avec une lamelle de connexion souple 27, 28.The conductive parts 23 a, 23 b respectively provide the electrical connection (phase and neutral) of the supply network, whereas the rigid blades 25 a, 25 b each cooperate with a flexible connection strip 27, 28.

La lamelle de connexion 27 est fixée au boîtier isolant 5 par l'intermédiaire de rivets 29 et 30 dont l'un et plus particulièrement le rivet 30 est traversé par une vis 22 permettant la fixation dudit boîtier isolant 5 sur l'embase 2 conductrice de la chaleur.The connection strip 27 is fixed to the insulating housing 5 by means of rivets 29 and 30, one and more particularly the rivet 30 is traversed by a screw 22 for fixing said insulating casing 5 to the conductive base 2 of the heat.

La lamelle de connexion 27 comporte à une extrémité un contact 31 qui vient en regard du contact 26a de la lame rigide 25a de la première pièce conductrice 23a, tandis que l'autre extrémité de la lamelle de connexion 27 est fixée à l'une des bornes d'entrée de connexion 14 de la résistance électrique 3 au moyen de la vis 22 et de l'écrou 21 correspondant.The connection strip 27 has at one end a contact 31 which faces 26a contacting the rigid strip 25 has the first conductive member 23 a, while the other end of the connecting strip 27 is attached to the one of the connection input terminals 14 of the electrical resistance 3 by means of the screw 22 and the corresponding nut 21.

De l'autre coté, la lamelle de connexion 28 est fixée au boîtier isolant 5 par un unique rivet 32 de manière que son premier contact 33 soit en regard du contact 26b de la lame rigide 25b de la seconde pièce conductrice 23b, tandis que son second contact 34 est en regard d'un contact 35 solidaire d'une lamelle élastique et conductrice 36 montée mobile et articulée par rapport à une pièce de connexion 38 fixée dans le boîtier isolant 5.On the other side, the connection strip 28 is attached to the insulative housing 5 by a single rivet 32 so that its first contact 33 is opposite the contact 26 b of the rigid blade 25 b of the second conductive member 23 b, while its second contact 34 is opposite a contact 35 secured to a resilient and conductive strip 36 mounted movably and articulated with respect to a connection piece 38 fixed in the insulating housing 5.

La lamelle élastique 36 coopère librement avec la pièce de connexion 38 qui est fixée au boîtier isolant 5 par l'intermédiaire de rivets 39 et 40 dont l'un et plus particulièrement le rivet 40 est traversé par une vis 22 permettant la fixation dudit boîtier isolant 5 sur l'embase 2 conductrice de la chaleur.The resilient lamella 36 cooperates freely with the connecting piece 38 which is fixed to the insulating casing 5 by means of rivets 39 and 40, one of which, and more particularly the rivet 40, is traversed by a screw 22 enabling the fixing of said insulating casing. 5 on the base 2 conducts heat.

La pièce de connexion 38 est destinée à assurer la liaison électrique avec l'autre borne de connexion 14 de la résistance électrique 3.The connecting piece 38 is intended to provide the electrical connection with the other connection terminal 14 of the electrical resistance 3.

Les lamelles de connexion 27, 28 sont actionnées par un coulisseau isolant 37 qui vient prendre appui sur le disque bimétallique 18 du coupe-circuit thermique de sécurité ou sur tout autre système de sécurité comme, par exemple, à ressort à mémoire de forme .The connecting strips 27, 28 are actuated by an insulating slider 37 which bears on the bimetallic disc 18 of the safety thermal cut-out or on any other safety system such as, for example, with a shape memory spring.

Le disque bimétallique 18 ou tout autre système de sécurité prend, par l'intermédiaire de l'embase 2 conductrice de la chaleur, la température de l'eau à l'intérieur de la cuve 7 du ballon d'eau chaude 8 et se déclenche ou se déforme brusquement pour une température prédéterminée en usine .The bimetallic disc 18 or any other safety system takes, via the heat conductive base 2, the temperature of the water inside the tank 7 of the hot water tank 8 and is triggered or deforms sharply for a predetermined temperature in the factory.

Le coulisseau isolant 37 traverse le boîtier isolant 5 pour venir déboucher à l'extérieur du dispositif de chauffage et de régulation 1 afin de permettre le réarmement manuel du coupe-circuit thermique de sécurité constitué, par exemple, par le disque bimétallique 18.The insulating slide 37 passes through the insulating casing 5 to open out of the heating and regulating device 1 in order to allow the manual reset of the safety thermal cut-off device constituted, for example, by the bimetallic disc 18.

Les lamelles de connexion 27, 28, le levier isolant 37 et le disque bimétallique 18 constituent le coupe-circuit thermique de sécurité du dispositif de chauffage et de régulation 1 afin de protéger le ballon d'eau chaude 8 et l'utilisateur contre une surchauffe éventuelle de l'eau contenue dans la cuve 7.The connecting strips 27, 28, the insulating lever 37 and the bimetallic disc 18 constitute the safety thermal cut-out of the heating and regulating device 1 in order to protect the hot water tank 8 and the user against overheating. possible water contained in the tank 7.

La lamelle élastique 36 assure l'ouverture brusque du circuit électrique en cas de dépassement de la température de consigne de régulation de l'eau à l'intérieur de la cuve 7 du ballon d'eau chaude 8.The elastic strip 36 ensures the sudden opening of the electrical circuit in the event of exceeding the regulation water temperature set within the tank 7 of the hot water tank 8.

A cet effet, la lamelle élastique 36 est actionnée par le levier isolant 20, coopérant avec la tige d'invar 16 disposée à l'intérieur du tube de la sonde de régulation 4.For this purpose, the elastic strip 36 is actuated by the insulating lever 20, cooperating with the invar rod 16 disposed inside the tube of the regulation probe 4.

La tige d'invar 16 permet de transmettre à la lamelle élastique 36 par l'intermédiaire du levier isolant 20 un mouvement qui est proportionnel à la dilatation du tube constituant la sonde, ledit tube étant réalisé dans un métal à fort coefficient de dilatation.The invar rod 16 makes it possible to transmit to the elastic strip 36 via the insulating lever 20 a movement which is proportional to the expansion of the tube constituting the probe, said tube being made of a metal with a high coefficient of expansion.

Egalement, le tube constituant la sonde de régulation 4 est solidaire de manière étanche à son extrémité libre et opposée à l'embase 2 conductrice de la chaleur de la tige d'invar 16 réalisée dans un métal à faible coefficient de dilatation.Also, the tube constituting the regulation probe 4 is sealingly secured at its free end and opposite to the heat conductive base 2 of the invar rod 16 made of a metal with a low coefficient of expansion.

Le dispositif de chauffage et de régulation 1 comporte une lampe 41 signalant à l'utilisateur que l'eau se trouvant à l'intérieur de la cuve 7 du ballon d'eau chaude 8 est en train de chauffer.
