Plus précisément la présente invention concerne un système de contrôle de la puissance de chauffe de tels dispositifs de chauffage par effet joule, notamment des convecteurs électriques.More specifically, the present invention relates to a system for controlling the heating power of such joule heating devices, including electric convectors.
De très nombreux logements ou bâtiments sont équipés de dispositifs de chauffage par effet joule, notamment de convecteurs électriques.Many houses or buildings are equipped with Joule effect heaters, including electric heaters.
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 boitiers 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 known manner an electric convector conventionally comprises a heating body connected to a power supply by a control box for defining a set temperature and a temperature sensor. Some recent devices include electronic control boxes or remotely controllable.

Ils sont cependant peu économes en énergie.Joule heating, especially electric convector, has been of great service. Electric convectors are inexpensive and easy to install. 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 source of significant power consumption and without any flexibility for the network manager, or for the user, who does not can realize the economy of invoice, nor to adapt correctly its comfort to its needs.

Les pattes 14, 16 peuvent être reliées partiellement par une cloison de liaison 19 représentée sur la
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 corps12, 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
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
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
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
Comme on le voit sur la
Le boitier 10 est fixé sur le boitier de convecteur électrique B par tous moyens appropriés.The
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
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 non-limiting example, the lower
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 entrainer tout en gardant une compacité maximum.The spacing between the lateral inner surfaces of each of the two
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 flanking the drive wheel M sloping, 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
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 different inclination inserts for adapting each
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

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
A l'utilisation, une fois le boitier 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

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.Naturally, the present invention is not limited to the coupling modes previously described but extends to any variant within 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 consider a magnetic coupling between the

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 include respective control means of each
La programmation de chaque boitier 10 peut également être opérée directement sur chaque boitier 10.The programming of each
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.In the context of the present invention is preferably provided a calibration method for determining, once each
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 according to the present invention essentially comprises the steps of, after having installed a
Une fois les positions extrêmes de la molette M connues le dispositif de pilotage peut déterminer les consignes spécifiques à chaque boitier 10 et à chaque application.Once the extreme positions of the knob M known, the control device can determine the specific instructions for each
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 varied in many variations depending on the servo motor technology used, for example an angle or voltage 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 incorporate a map of the existing convectors and wheels M and thus the angle necessary to move on the different graduations of the wheel between its minimum position and its maximum position for each known wheel.
Le 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.The calibration means can be content in this case to find the two extreme stop points of the wheel M, by doing this to a measurement of the amplitude of displacement of the servomotor or the displacement time 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 drive means of the
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 has previously been indicated that the extreme positions of the wheel M can be detected by analyzing the torque or the voltage on the
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 many 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 the existing electric heaters and consequently to preserve the existing park, 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 makes it possible for 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 an old equipment into a more efficient connected system, without the need to dismantle or replace the conventional M-wheel of the 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.Moreover, the present invention offers great economic advantages. The invention makes it possible to freely program reduced consumption ranges 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 %.Simulations carried out by the Applicant demonstrate, thanks to the possibility of switching to economic mode by programming, consumption gains greater 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 conforme à son esprit.Of course, the present invention is not limited to the particular embodiments which have just been described but extends to any variant within its spirit.
