Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne le domaine des dispositifs de chauffage par effet joule, formant des convecteurs électriques.The invention relates to the field of heating devices by Joule effect, forming electric convectors.

Plus précisément la présente invention concerne des convecteurs électriques munis d'un système de contrôle de la puissance de chauffe de tels dispositifs de chauffage par effet joule.More specifically, the present invention relates to electric convectors provided with a system for controlling the heating power of such Joule effect heating devices.

ETAT DE LA TECHNIQUESTATE OF THE ART

De très nombreux logements ou bâtiments sont équipés de dispositifs de chauffage par effet joule, notamment de convecteurs électriques.Many dwellings or buildings are equipped with Joule effect heating devices, in particular electric convectors.

De façon connue en soi un convecteur électrique comprend de manière classique un corps de chauffe relié à une alimentation électrique par un boitier de commande destiné à définir une température de consigne et une sonde de température. Certains appareils récents comprennent des boîtiers de commande électroniques, voire pilotables à distance. Cependant la plupart des appareils existants comprennent un dispositif de commande mécanique, le plus souvent de type molette rotative destinée à définir la température de consigne. De tels systèmes offrent peu de souplesse à l'utilisation.In a manner known per se, an electric convector conventionally comprises a heating body connected to an electrical supply by a control unit intended to define a set temperature and a temperature probe. Some recent devices include electronic control units, or even remotely controllable. However, most of the existing devices include a mechanical control device, most often of the rotary wheel type intended to define the set temperature. Such systems offer little flexibility in use.

En France on estime le parc de convecteurs électriques à environ 60 millions d'unités.In France, the electric convector fleet is estimated at around 60 million units.

Le chauffage par effet joule, notamment par convecteur électrique, a rendu de grands services. Les convecteurs électriques constituent des équipements peu chers et d'installation simple. Ils sont cependant peu économes en énergie.Heating by Joule effect, in particular by electric convector, has rendered great services. Electric convectors are inexpensive and easy to install equipment. However, they are not very energy efficient.

Cependant la très grande majorité de ces dispositifs n'est actuellement pas raccordé à un fil pilote ou ne dispose pas de gestionnaire d'énergie. Cela en fait une source de consommation électrique importante et sans aucune flexibilité pour le gestionnaire de réseau, ni pour l'usager, qui ne peut réaliser l'économie de facture, ni adapter correctement son confort à ses besoins.However, the vast majority of these devices are currently not connected to a pilot wire or do not have an energy manager. This makes it a significant source of electrical consumption and without any flexibility for the network operator, nor for the user, who does not can save money, nor properly adapt its comfort to its needs.

On trouvera des exemples de dispositifs connus dans le domaine général du chauffage, dans les documents EP 2 677 216 et EP 1 170 338 .Examples of known devices in the general field of heating can be found in the documents EP 2,677,216 and EP 1,170,338 .

Le document EP 2 677 216 décrit des moyens de commande d'une soupape de régulation d'un corps de chauffe.The document EP 2,677,216 describes means for controlling a regulating valve of a heating body.

Le document EP 1 170 338 décrit des moyens de pilotage d'un interrupteur placé entre une source d'alimentation électrique et la sortie de commande d'un corps de chauffe.The document EP 1,170,338 describes means for controlling a switch placed between an electric power source and the control output of a heating body.

Les moyens décrits dans les deux documents précités sont complexes.The means described in the two aforementioned documents are complex.

On trouvera d'autres exemples de tentatives conformes à l'état de la technique dans les documents DE 10 290 23 282 , US 2012 / 0248204 , GB 2455886 , DE 10 20 11015659 , DE 102008058364 , EP 2 216 606 , FR 2 982 346 , GB 2519441 , US 2012 / 0130547 , WO 2014 / 055059 , WO 2003 / 084022 et WO 2008 / 0125875 .Other examples of prior art attempts can be found in the documents DE 10 290 23 282 , US 2012/0248204 , GB 2455886 , DE 10 20 11 015 659 , DE 102008058364 , EP 2,216,606 , FR 2 982 346 , GB 2519441 , US 2012/0130547 , WO 2014/055059 , WO 2003/084022 and WO 2008/0125875 .

Les documents FR 2891635 , DE 20210371 et EP 2216606 divulguent différents dispositifs visant à piloter à distance un appareil de chauffage par effet joule. Le document FR 2 891 635 divulgue un convecteur trique ayant les caractéristiques du préambule de la revendication 1.The documents FR 2891635 , DE 20210371 and EP 2216606 disclose various devices for remotely controlling a Joule effect heater. The document FR 2 891 635 discloses a tin convector having the characteristics of the preamble of claim 1.

En synthèse l'homme de l'art ressent la nécessité de faire évoluer les moyens existants, mais malgré les efforts déployés en la matière, force est de constater que le domaine du chauffage par effet joule, notamment des convecteurs électriques n'a pas beaucoup évolué depuis de nombreuses années.In summary, those skilled in the art feel the need to develop existing means, but despite the efforts made in this area, it must be noted that the field of heating by Joule effect, in particular electric convectors, does not have much evolved for many years.

DESCRIPTION DETAILLEE D'AU MOINS UN MODE DE REALISATION DE L'INVENTIONDETAILED DESCRIPTION OF AT LEAST ONE EMBODIMENT OF THE INVENTION

La structure d'un convecteur électrique est connue et ne sera pas décrite par la suite.The structure of an electric convector is known and will not be described below.

On rappelle cependant qu'un convecteur électrique comprend classiquement un boitier B qui loge un corps de chauffe destiné à être relié à une alimentation électrique par l'intermédiaire d'un boitier de commande comprenant généralement une sonde de température et un élément de définition de consigne formé le plus souvent d'une molette rotative M. Comme on l'a représenté sur la figure 1, une telle molette M est le plus souvent englobée quasi totalement dans l'enveloppe du boitier B, tout en émergeant cependant sur une partie de sa périphérie pour permettre une commande manuelle aisée. Plus précisément encore sur la plupart des modèles de convecteurs électriques connus, la partie accessible de la molette M fait saillie au niveau d'un décrochement du boitier B qui possède typiquement une facette F1 parallèle à l'axe de rotation A-A de la molette M et une facette F2 perpendiculaire à cet axe A-A de rotation de la molette M.It is recalled, however, that an electric convector conventionally comprises a box B which houses a heating body intended to be connected to an electrical supply by means of a control box generally comprising a temperature probe and a setpoint definition element. usually formed by a rotary wheel M. As shown in the figure 1 , such a thumbwheel M is most often almost completely encompassed in the envelope of the housing B, while however emerging on a part of its periphery to allow easy manual control. More precisely still on most of the known electric convector models, the accessible part of the wheel M projects at the level of a recess of the housing B which typically has a facet F1 parallel to the axis of rotation AA of the wheel M and a facet F2 perpendicular to this axis AA of rotation of the thumb wheel M.

Le système de contrôle de puissance de chauffe équipant un convecteur électrique conforme à l'invention comprend essentiellement au moins un dispositif comportant un boitier 10 qui loge un actionneur 20 et un moyen d'entrainement 30.The heating power control system equipping an electric convector according to the invention essentially comprises at least one device comprising a box 10 which houses an actuator 20 and a drive means 30.

Un tel dispositif ou boitier de contrôle 10, est destiné à être disposé sur un appareil existant type convecteur électrique ou équivalent afin d'en améliorer la commande et le fonctionnement.Such a device or control box 10 is intended to be placed on an existing appliance of the electric convector type or equivalent in order to improve its control and operation.

Un système conforme à la présente invention peut ne comprendre qu'un seul boitier de contrôle 10.A system according to the present invention may comprise only a single control unit 10.

Cependant dans le cadre de l'invention le système comprend de préférence une pluralité de boîtiers de contrôle 10 associés respectivement aux différents convecteurs électriques de chauffage d'un logement ou bâtiment.However, within the framework of the invention, the system preferably comprises a plurality of control boxes 10 associated respectively with the various electric convectors for heating a dwelling or building.

Le dispositif de contrôle conforme à la présente invention comprend en outre des moyens 40 de pilotage de l'actionneur 20.The control device according to the present invention further comprises means 40 for controlling the actuator 20.

Comme on le verra par la suite les moyens de pilotage 40 peuvent être soit intégrés au boitier 10 soit décentralisés par rapport à celui-ci.As will be seen below, the control means 40 can be either integrated into the housing 10 or decentralized with respect to the latter.

Le boitier 10 peut faire l'objet de nombreuses variantes de réalisation.The housing 10 can be the subject of numerous variant embodiments.

De préférence comme on l'a représenté notamment sur les figures 5, 9, 10 et 11, le boitier 10 comprend un corps 12 destiné à être placé à proximité de la molette de réglage M classique d'un convecteur électrique existant. Plus précisément de préférence le corps 12 est adapté pour chevaucher et encadrer en partie la molette de réglage précitée M.Preferably as shown in particular on the figures 5 , 9, 10 and 11 , the housing 10 comprises a body 12 intended to be placed near the conventional adjustment wheel M of an existing electric convector. More precisely, preferably the body 12 is adapted to overlap and partially frame the aforementioned adjustment wheel M.

A cette fin de préférence comme représenté sur les figures 5, 9, 10 et 11, le boitier 10 comprend deux pattes 14, 16 généralement parallèles entre elles, destinées à être positionnées de part et d'autre d'une roue 32 appartenant aux moyens d'entrainement et destinés à coopérer avec la molette M.For this purpose preferably as shown in the figures 5 , 9, 10 and 11 , the housing 10 comprises two legs 14, 16 generally parallel to each other, intended to be positioned on either side of a wheel 32 belonging to the drive means and intended to cooperate with the wheel M.

Les pattes 14, 16 peuvent être reliées partiellement par une cloison de liaison 19 représentée sur la figure 5, qui recouvre partiellement la roue 32.The legs 14, 16 can be partially connected by a connecting partition 19 shown on the figure 5 , which partially covers the wheel 32.

Comme on le voit sur les figures la roue 32 reste cependant accessible sur une partie de sa périphérie, au niveau d'une fenêtre définie entre la face extérieure du corps 12, les pattes 14, 16 et la cloison 19, pour permettre de mettre en contact la périphérie de la roue 32 et la molette M, dans le cas de couplage par contact représenté sur la figure 7.As can be seen in the figures, the wheel 32 remains accessible over a part of its periphery, at the level of a window defined between the external face of the body 12, the lugs 14, 16 and the partition 19, in order to allow contact the periphery of the wheel 32 and the thumbwheel M, in the case of contact coupling shown in the figure 7 .

L'actionneur 20 peut être formé de tout moyen approprié connu de l'homme de l'art. Il s'agit de préférence d'un servo-moteur à commande électrique.The actuator 20 can be formed by any suitable means known to those skilled in the art. It is preferably an electrically controlled servo motor.

A titre d'exemple non limitatif le servo-moteur 20 peut être formé d'un servo-moteur miniature à rotation continue sur une course de 360 degrés, à alimentation en courant continu typiquement de 4,8 à 6 Volts.By way of nonlimiting example, the servo motor 20 can be formed of a miniature servo motor with continuous rotation over a stroke of 360 degrees, with direct current supply typically from 4.8 to 6 Volts.

Les moyens d'entrainement 30 comprennent de préférence une roue 32 couplée à l'arbre de sortie du servo-moteur 20 et guidée ainsi à rotation autour d'un axe O-O parallèle à l'utilisation à l'axe de rotation A-A de la molette du convecteur électrique équipé.The drive means 30 preferably comprise a wheel 32 coupled to the output shaft of the servo-motor 20 and thus guided in rotation about an axis OO parallel to the use of the axis of rotation AA of the wheel. of the equipped electric convector.

Comme on le voit sur la figure 5 de préférence la roue d'entrainement 32 est revêtue d'une bande ou anneau élastique 34 permettant d'améliorer l'entrainement de la molette M du convecteur par friction.As seen on the figure 5 preferably the drive wheel 32 is coated with an elastic band or ring 34 enabling the drive of the knob M of the convector to be improved by friction.

Le boitier 10 est fixé sur le boîtier de convecteur électrique B par tous moyens appropriés.The box 10 is fixed to the electric convector box B by any suitable means.

Le boitier 10 peut être fixé sur le boitier B de convecteur électrique par collage, par exemple à l'aide de pastilles adhésives haute résistance 18, 19 disposées sur les surfaces d'extrémités 15, 17 des pattes 14, 16 comme on le voit sur la figure 9. Selon le mode de réalisation illustré sur la figure 9, les faces 15 et 17 sont coplanaires et les pastilles 18, 19 sont destinées à reposer sur la facette F1 du boitier B de convecteur, plus précisément sur deux surfaces planes coplanaires composant la facette F1, de part est d'autre de la molette M et sur lesquelles les pattes 14, 16 sont positionnées.The box 10 can be fixed on the box B of the electric convector by gluing, for example using high resistance adhesive pads 18, 19 placed on the end surfaces 15, 17 of the tabs 14, 16 as seen on the figure 9 . According to the embodiment illustrated in the figure 9 , the faces 15 and 17 are coplanar and the pads 18, 19 are intended to rest on the facet F1 of the case B of the convector, more precisely on two flat surfaces coplanar components of facet F1, on either side of the thumbwheel M and on which the legs 14, 16 are positioned.

A titre d'exemple non limitatif les surfaces planes inférieures 15, 17 de chacune des deux pattes 14, 16 peuvent être de 5x5 mm.By way of nonlimiting example, the lower planar surfaces 15, 17 of each of the two tabs 14, 16 can be 5 × 5 mm.

L'écartement entre les surfaces intérieures latérales de chacune des deux pattes 14, 16 est de préférence compris entre 1 et 3 cm de sorte que les pattes 14, 16 viennent se positionner sur la surface précitée F1. L'écartement entre les pattes 14, 16 est choisi de sorte que ces pattes n'interfèrent pas avec la molette M à entraîner tout en gardant une compacité maximum.The spacing between the lateral interior surfaces of each of the two legs 14, 16 is preferably between 1 and 3 cm so that the legs 14, 16 are positioned on the aforementioned surface F1. The spacing between the tabs 14, 16 is chosen so that these tabs do not interfere with the thumb wheel M to be driven while keeping maximum compactness.

Certains convecteurs ont une surface F1 encadrant la molette M d'entrainement pentue, c'est-à-dire inclinée par rapport à l'horizontale.Some convectors have a surface F1 surrounding the sloping drive wheel M, that is to say inclined relative to the horizontal.

Dans ce contexte on peut prévoir que les surfaces inférieures 15, 17 des pattes 14, 16 soient inclinées ou décalées en correspondance, ou l'on peut prévoir un insert en forme de coin destiné à être intercalé entre la surface inférieure 15, 16 des pattes 14, 17 et la surface précitée F1 pentue du boitier B de convecteur.In this context it can be provided that the lower surfaces 15, 17 of the legs 14, 16 are inclined or offset in correspondence, or one can provide a wedge-shaped insert intended to be interposed between the lower surface 15, 16 of the legs 14, 17 and the abovementioned surface F1 of the convector box B.

On peut ainsi prévoir des jeux d'inserts d'inclinaisons différentes permettant d'adapter chaque boitier de commande 10 à chaque convecteur à équiper.It is thus possible to provide sets of inserts with different inclinations making it possible to adapt each control unit 10 to each convector to be equipped.

Plus généralement on peut prévoir dans le cadre de la présente invention un jeu de kits formés d'intercalaires ayant d'une part une forme géométrique complémentaire du corps 12 et d'autre part une autre forme géométrique complémentaire d'une partie de l'enveloppe du boitier B de sorte que une fois le bon intercalaire choisi, un boitier 12 de dispositif de contrôle puisse toujours être supporté en position adéquate sur le convecteur associé, avec un positionnement précis de la roue 32 en position de couplage avec une molette M, par exemple adjacente à la molette M selon la figure 7.More generally, it is possible to provide, in the context of the present invention, a set of kits formed of spacers having on the one hand a geometric shape complementary to the body 12 and on the other hand another geometric shape complementary to a part of the envelope of the housing B so that once the correct insert has been chosen, a housing 12 of the control device can always be supported in an adequate position on the associated convector, with precise positioning of the wheel 32 in the coupling position with a thumbwheel M, by example adjacent to the M wheel according to the figure 7 .

Comme on le voit notamment sur la figure 2, de préférence la surface extérieure de la roue d'entrainement 32 ou de la bande en élastomère 34 est située en retrait vers l'intérieur par rapport aux surfaces d'extrémité 15, 17 des pattes, 14, 16 à une distance telle que lorsque le boitier 10 est placé en position sur un boitier B de convecteur, la roue 32 ou la bande en élastomère 34 vient au moins en contact, au mieux en appui, sur la molette M du convecteur.As we see in particular on the figure 2 , preferably the outer surface of the drive wheel 32 or of the elastomer strip 34 is set back inwards relative to the end surfaces 15, 17 of the legs, 14, 16 at a distance such that when the housing 10 is placed in position on a convector housing B, the wheel 32 or the elastomer strip 34 comes at least into contact, at best in support, on the convector wheel M.

La bande en élastomère 34 permet de compenser les éventuels écarts entre la roue d'entrainement 32 et la molette M du convecteur.The elastomer strip 34 makes it possible to compensate for any deviations between the drive wheel 32 and the knob M of the convector.

On a représenté sur la figure 10 des pastilles intercalaires 50 susceptibles d'être intercalées entre la surface inférieure 15, 17 des pattes 14, 16 et la surface support F1 du convecteur électrique pour ajuster le positionnement de la roue d'entrainement 32 ou de la bande en élastomère 34 par rapport à la molette M du convecteur. Le boitier 10 peut être fixé également sur le boitier B de convecteur électrique par tout autre moyen amovible approprié, par exemple par des moyens magnétiques, un système de sangle ou tout autre moyen équivalent amovible. On a ainsi représenté sur la figure 11 un aimant 60 sous forme d'une lame destinée à chevaucher partiellement le boitier 10 de contrôle conforme à l'invention et une partie métallique du boitier B de convecteur électrique, en l'espèce la face supérieure F3 de ce boitier B, pour plaquer le boitier 10 du dispositif de contrôle conforme à l'invention contre le boitier B du convecteur électrique, plus précisément contre la facette F1 du boitier B.We have represented on the figure 10 insert pads 50 capable of being inserted between the lower surface 15, 17 of the tabs 14, 16 and the support surface F1 of the electric convector to adjust the positioning of the drive wheel 32 or of the elastomer strip 34 relative to the convector wheel M. The box 10 can also be fixed on the box B of the electric convector by any other suitable removable means, for example by magnetic means, a strap system or any other equivalent removable means. We have thus represented on the figure 11 a magnet 60 in the form of a blade intended to partially overlap the control unit 10 in accordance with the invention and a metallic part of the unit B of the electric convector, in this case the upper face F3 of this unit B, to press the box 10 of the control device according to the invention against the box B of the electric convector, more precisely against the facet F1 of the box B.

On aperçoit par ailleurs sur la figure 5 une variante d'implantation d'un aimant 60 destiné à être placé entre la surface arrière du boitier 10 transversale à l'axe de rotation O-O et la surface F2 en regard du boitier B de convecteur électrique.We can also see on the figure 5 a variant implantation of a magnet 60 intended to be placed between the rear surface of the housing 10 transverse to the axis of rotation OO and the surface F2 facing the housing B of the electric convector.

On aperçoit également sur la figure 5 une source électrique type batterie ou accumulateur référencée 70, une carte de microcontrôleur 72 et un module 74 de communication par liaison sans fil, intégrés dans le corps 12 du boitier 10.We also see on the figure 5 a battery or accumulator type electrical source referenced 70, a microcontroller card 72 and a wireless communication module 74, integrated in the body 12 of the housing 10.

La carte 72 constitue une partie au moins des moyens de pilotage 40.The card 72 constitutes at least part of the control means 40.

Le module 74 est destinée à assurer la communication avec des moyens de commande externe 100.The module 74 is intended to ensure communication with external control means 100.

La source électrique 70 est destinée à assurer l'alimentation électrique de la carte 72, du module 74 et du servo-moteur 20.The electrical source 70 is intended to supply electrical power to the card 72, the module 74 and the servo motor 20.

Les moyens de couplage entre la roue d'entrainement 32 du dispositif amovible conforme à l'invention et la molette M du convecteur électrique peuvent faire l'objet de nombreuses variantes de réalisation.The coupling means between the drive wheel 32 of the removable device according to the invention and the knob M of the electric convector can be the subject of numerous variant embodiments.

A l'utilisation, une fois le boîtier 10 fixé sur le boitier B de convecteur, l'axe de sortie du servo-moteur 20 et de la roue associée 32 et l'axe de la molette M, sont de préférence parallèles entre eux. Sur la figure 6, ces moyens de couplage sont formés d'une courroie 80 engagée à la fois sur la roue 32 et sur la périphérie de la molette M.In use, once the housing 10 is fixed on the convector housing B, the output axis of the servo-motor 20 and of the associated wheel 32 and the axis of the thumbwheel M are preferably parallel to each other. On the figure 6 , these coupling means are formed of a belt 80 engaged both on the wheel 32 and on the periphery of the wheel M.

On a représenté sur la figure 7 un couplage par contact entre la bande en élastomère 34 et la molette M.We have represented on the figure 7 a contact coupling between the elastomer strip 34 and the thumb wheel M.

On a représenté sur la figure 8 un couplage entre la roue 32 des moyens de contrôle et la molette M par un système de biellette 82 dont les extrémités sont fixées en position choisie respectivement sur la roue 32 et sur la molette M. Pour permettre un réglage des positions respectives, amplitudes de déplacement et point de départ et point d'arrivée des courses, il peut être prévu à cette fin tant sur la molette M que sur la roue 32 une pluralité de points potentiels de fixation des extrémités de la biellette 82 susceptibles d'être sélectivement choisis par l'installateur. L'on peut prévoir pour cela un disque comportant les points de fixation précités adapté pour être collé ou fixé par tous moyens équivalents sur la face extérieure accessible de la molette M.We have represented on the figure 8 coupling between the wheel 32 of the control means and the wheel M by a link system 82, the ends of which are fixed in the chosen position respectively on the wheel 32 and on the wheel M. To allow adjustment of the respective positions, amplitudes of movement and starting point and end point of the races, there can be provided for this purpose both on the wheel M and on the wheel 32 a plurality of potential points of attachment of the ends of the rod 82 capable of being selectively chosen by the installer. One can provide for this a disc comprising the aforementioned fixing points adapted to be glued or fixed by any equivalent means on the accessible external face of the wheel M.

Bien entendu la présente invention n'est pas limitée aux modes de couplage précédemment décrits mais s'étend à toute variante conforme à son esprit.Of course the present invention is not limited to the coupling modes described above but extends to any variant in accordance with its spirit.

On peut ainsi envisager également un couplage magnétique entre la roue 32 et la molette M en prévoyant des aimants respectifs sur ces deux éléments ou encore en plaçant une roue auxiliaire couplée à la roue 32 en regard de la molette M avec couplage magnétique entre ces éléments.One can thus also envisage a magnetic coupling between the wheel 32 and the thumbwheel M by providing respective magnets on these two elements or by placing an auxiliary wheel coupled to the wheel 32 opposite the wheel M with magnetic coupling between these elements.

On a représenté sur la figure 3 un ensemble conforme à la présente invention comprenant trois boîtiers de commande 10 destinés à être fixés sur des convecteurs électriques respectifs, et couplés à des moyens 40 de pilotage excentrés.We have represented on the figure 3 an assembly according to the present invention comprising three control boxes 10 intended to be fixed on respective electric convectors, and coupled to eccentric control means 40.

Plus précisément selon la figure 3, ces moyens 40 comprennent un boitier maître 100 lui-même piloté par une box wifi 110 commandée par une application mobile type tablette ou smartphone 120.More precisely according to the figure 3 , these means 40 comprise a master unit 100 itself controlled by a wifi box 110 controlled by a mobile application such as a tablet or smartphone 120.

Dans cette configuration les signaux de commande du servo-moteur 20 sont adressés par le boitier maître 100.In this configuration, the control signals of the servomotor 20 are sent by the master unit 100.

On a représenté sur la figure 4 une configuration différente dans laquelle l'application mobile 120 applique directement les consignes à chaque boitier 10.We have represented on the figure 4 a different configuration in which the mobile application 120 directly applies the instructions to each box 10.

Les moyens de commande par application mobile peuvent bien entendu comprendre des moyens de pilotage respectifs de chaque boitier 10, ainsi qu'un calendrier de programmation, typiquement un calendrier de présence/absence permettant une commande automatique en mode économique pendant les temps d'absence.The mobile application control means can of course comprise respective control means for each unit 10, as well as a programming calendar, typically a presence / absence calendar allowing automatic control in economic mode during the absence times.

La programmation de chaque boitier 10 peut également être opérée directement sur chaque boitier 10.The programming of each box 10 can also be carried out directly on each box 10.

Dans le cadre de la présente invention il est prévu de préférence un procédé d'étalonnage permettant de déterminer, une fois chaque boitier 10 installé sur le boitier B d'un convecteur électrique respectif, les positions extrêmes du seuil minimum et du seuil maximum de la molette M associée. Ce processus d'étalonnage permet d'appairer chaque boitier 10 au convecteur associé, plus précisément au positionnement et à l'amplitude de déplacement de la molette M associée.Within the framework of the present invention there is preferably provided a calibration method making it possible to determine, once each box 10 installed on the box B of a respective electric convector, the extreme positions of the minimum threshold and the maximum threshold of the associated M wheel. This calibration process makes it possible to pair each box 10 with the associated convector, more precisely with the positioning and the amplitude of movement of the associated wheel M.

Le procédé d'étalonnage conforme à la présente invention comprend essentiellement des étapes consistant, après avoir installé un boitier de contrôle 10 sur un boitier B de convecteur électrique, à procéder à une commande des moyens d'entrainement 30 vers une position de chauffage maximale et vers une position de chauffage minimale et détection des butées de molette M par tous moyens appropriés, par exemple par mesure de couple ou de variation de tension sur le servo-moteur 20.The calibration method in accordance with the present invention essentially comprises steps consisting, after having installed a control box 10 on a box B of electric convector, to proceed to a control of the drive means 30 to a maximum heating position and to a minimum heating position and detection of the wheel stops M by any appropriate means, for example by measuring torque or voltage variation on the servo motor 20 .

Une fois les positions extrêmes de la molette M connues le dispositif de pilotage peut déterminer les consignes spécifiques à chaque boîtier 10 et à chaque application.Once the extreme positions of the wheel M are known, the control device can determine the instructions specific to each box 10 and to each application.

Le processus d'étalonnage peut faire l'objet de nombreuses variantes notamment selon la technologie de servo-moteur utilisée, par exemple un contrôle d'angle ou de tension.The calibration process can be subject to numerous variations, in particular depending on the servo motor technology used, for example an angle or tension control.

Le processus d'étalonnage peut également intégrer une cartographie des convecteurs et molettes M existantes et donc de l'angle nécessaire pour se déplacer sur les différentes graduations de la molette entre sa position minimale et sa position maximale, pour chaque molette connue.The calibration process can also integrate a mapping of the existing convectors and knobs M and therefore of the angle necessary to move on the different graduations of the knurl between its minimum position and its maximum position, for each known knurl.

Les moyens d'étalonnage peuvent se contenter dans ce cas de rechercher les deux points de butée extrêmes de la molette M, en procédant pour cela à une mesure de l'amplitude de déplacement du servo-moteur ou du temps de déplacement par rapport à une référence.In this case, the calibration means can be satisfied with finding the two extreme stop points of the wheel M, by doing this for a measurement of the amplitude of movement of the servo-motor or of the time of travel with respect to a reference.

Le temps ou l'amplitude mesurés entre les deux points extrêmes détermine la plage de fonctionnement. Les moyens de pilotage du servo-moteur 20 peuvent ainsi déterminer la consigne à appliquer au servo-moteur pour déplacer celui-ci à la position recherchée dans la plage précitée.The time or amplitude measured between the two extreme points determines the operating range. The servo motor control means 20 can thus determine the setpoint to be applied to the servo motor to move the latter to the desired position in the aforementioned range.

L'on a indiqué précédemment que les positions extrêmes de la molette M peuvent être détectées par analyse du couple ou de la tension sur le servo-moteur 20. Ces positions extrêmes peuvent être détectées par tous moyens équivalents, par exemple par analyse de bruit grâce à un capteur sonore, de vitesse de rotation, de vibrations, ou encore par détection optique ou magnétique en disposant des marquages appropriés sur la molette M.It was previously indicated that the extreme positions of the thumbwheel M can be detected by analyzing the torque or the voltage on the servo-motor 20. These extreme positions can be detected by any equivalent means, for example by noise analysis using to a sound, speed, vibration, or optical or magnetic sensor by placing appropriate markings on the M wheel.

Par rapport à l'état de la technique la présente invention offre de nombreux avantages.Compared to the state of the art, the present invention offers numerous advantages.

Elle permet en effet d'équiper les convecteurs électriques existants et par conséquent de conserver le parc existant, par tout particulier sans faire appel à un professionnel.It makes it possible to equip existing electric convectors and therefore to keep the existing fleet, by any individual without calling on a professional.

Le dispositif de fixation proposé dans le cadre de la présente invention permet en effet à tout particulier d'équiper lui-même ses propres convecteurs. L'on observera que le système conforme à la présente invention permet de transformer un équipement ancien en un système connecté plus performant, et ce sans nécessité d'opération de démontage ou de remplacement de la molette M classique des équipements existants.The fixing device proposed in the context of the present invention indeed allows any individual to equip himself his own convectors. It will be observed that the system according to the present invention makes it possible to transform old equipment into a more efficient connected system, and this without the need to dismantle or replace the conventional thumbwheel M of existing equipment.

Par ailleurs la présente invention offre de grands avantages économiques. L'invention permet en effet de programmer librement des plages de consommation réduite sur chaque convecteur, tant en journée que la nuit.Furthermore, the present invention offers great economic advantages. The invention makes it possible to freely program ranges of reduced consumption on each convector, both during the day and at night.

Des simulations opérées par la Demanderesse démontrent en effet, grâce à la possibilité de passer en mode économique par programmation, des gains de consommation supérieurs à 20 %.In fact, simulations carried out by the Applicant demonstrate, by virtue of the possibility of switching to economic mode by programming, consumption savings of more than 20%.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits mais s'étend à toute variante décrite dans les revendications.Of course, the present invention is not limited to the particular embodiments which have just been described but extends to any variant described in the claims.
