La présente invention intéresse particulièrement le domaine de l'élaboration de boissons et de préparations culinaires, aussi bien dans le secteur professionnel que dans le secteur du grand public.The present invention is of particular interest in the field of preparing beverages and culinary preparations, both in the professional sector and in the general public sector.
Le dispositif selon l'invention peut par exemple, non limitatvement, présenter un intérêt particulier dans le domaine de la préparation de boissons tels que des cocktails, dont certains nécessitent d'être élaborés dans des conditions particulières de température.The device according to the invention can, for example, without limitation, be of particular interest in the field of the preparation of drinks such as cocktails, some of which need to be prepared under specific temperature conditions.
On connaît déjà de nombreux dispositifs permettant de porter un liquide à une certaine température et de l'y maintenir. Les plus courants de ces dispositifs sont ceux qui fonctionnent sur le principe du bain-marie, comme le chauffe-biberon par exemple.Numerous devices are already known which make it possible to bring a liquid to a certain temperature and to maintain it there. The most common of these devices are those that operate on the principle of a double boiler, such as a bottle warmer for example.
L'inconvénient de ces dispositifs réside dans le fait que la température est difficilement maîtrisable, non seulement pour l'atteindre, mais également pour la maintenir.The disadvantage of these devices lies in the fact that the temperature is difficult to control, not only to reach it, but also to maintain it.
Pour pallier cet inconvénient il a été proposé de nombreux dispositifs fonctionnant selon un autre principe, et notamment par l'utilisation d'éléments thermoélectriques à effet Peltier, qui permettent de dispenser aussi bien du chaud que du froid, en sorte d'obtenir et de maintenir une température précise.To overcome this drawback, numerous devices have been proposed operating according to another principle, and in particular by the use of thermoelectric elements with Peltier effect, which make it possible to dispense both hot and cold, so as to obtain and maintain a precise temperature.
Un tel dispositif est décrit dans le document FR 2.759.774, il comporte un récipient dont la paroi latérale renferme des éléments thermoélectriques à effet Peltier, et à l'intérieur duquel est disposée une enveloppe souple et étanche contenant un fluide caloporteur, destinée à recevoir un contenant de type boîte ou bouteille renfermant le liquide à amener à température. Les éléments thermoélectriques transmettent les calories ou les frigories au fluide caloporteur lequel les transmet au contenant.Such a device is described in the document FR 2,759,774, it comprises a container whose side wall contains thermoelectric elements with Peltier effect, and inside which is arranged a flexible and sealed envelope containing a heat transfer fluid, intended to receive a container type box or bottle containing the liquid to be brought to temperature. The thermoelectric elements transmit calories or frigories to the heat transfer fluid which transmits them to the container.
Un tel dispositif est d'une grande complexité de fabrication, ainsi que d'une utilisation et d'un entretien peu aisés.Such a device is very complex to manufacture, as well as difficult to use and maintain.
La présente invention a pour but de proposer un dispositif électronique pour porter un élément liquide ou solide à une température donnée permettant de remédier aux divers inconvénients précités.The object of the present invention is to propose an electronic device for bringing a liquid or solid element to a given temperature making it possible to remedy the various aforementioned drawbacks.
Le dispositif électronique pour porter un élément liquide ou solide à une température donnée selon l'invention est du type utilisant des éléments thermoélectriques à effet Peltier, et il se caractérise essentiellement en ce qu'il comprend deux parties adaptables l'une à l'autre de manière réversible, à savoir un récipient destiné à contenir l'élément liquide ou solide à amener à la température voulue, et un réceptacle destiné à recevoir ledit récipient ; et en ce que ledit récipient comporte un ensemble de moyens électroniques incorporé à sa paroi et qui comprend des éléments thermoélectriques à effet Peltier ainsi qu'un capteur de température associé à des moyens de mémoire prévus pour mémoriser ladite température, tandis que ledit réceptacle renferme une platine électronique et un moyen de production ou de transformation d'énergie électrique, lesdits moyens électroniques et ladite platine électronique étant aptes à être reliés au travers de moyens de connexion par contact.The electronic device for bringing a liquid or solid element to a given temperature according to the invention is of the type using thermoelectric elements with Peltier effect, and it is essentially characterized in that it comprises two parts adaptable to one another reversibly, namely a container intended to contain the liquid or solid element to be brought to the desired temperature, and a receptacle intended to receive said container; and in that said container comprises a set of electronic means incorporated into its wall and which includes Peltier thermoelectric elements as well as a temperature sensor associated with memory means provided for memorizing said temperature, while said receptacle contains a electronic board and a means of producing or transforming electrical energy, said electronic means and said electronic board being able to be connected through contact connection means.
Avantageusement, après détermination de la température et enregistrement de celle-ci au travers des moyens de mémoire, le récipient peut être associé à différents réceptacles sans que cela nécessite une reprogrammation de ladite température. Selon une caractéristique additionnelle du dispositif selon l'invention, les moyens électroniques comportent des moyens de programmation aptes à permettre, par l'intermédiaire des éléments thermoélectriques, de maintenir l'élément liquide ou solide à une température de consigne proche de la température d'exploitation voulue, puis, à la demande, à amener ledit élément liquide ou solide à ladite température d'exploitation.Advantageously, after determining the temperature and recording it through memory means, the container can be associated with different receptacles without this requiring reprogramming of said temperature. According to an additional characteristic of the device according to the invention, the electronic means comprise programming means able to allow, by means of the thermoelectric elements, to maintain the liquid or solid element at a set temperature close to the temperature of desired operation, then, on request, bringing said liquid or solid element to said operating temperature.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, le récipient est apte à être posé et calé sur le réceptacle, tandis que les moyens de connexion comprennent d'une part, au niveau dudit réceptacle, des palpeurs à ressort répartis selon des cercles concentriques, et d'autre part, au niveau du récipient, des conducteurs en forme d'anneaux concentriques chacun apte à entrer en contact avec un seul desdits palpeurs.According to another additional characteristic of the device according to the invention, the container is capable of being placed and wedged on the receptacle, while the connection means comprise on the one hand, at the level of said receptacle, spring feelers distributed in circles concentric, and secondly, at the level of the container, conductors in the form of concentric rings each capable of coming into contact with only one of said feelers.
Les conducteurs sont disposés sous le fond du récipient et les palpeurs font saillie du réceptacle, cette architecture permettant que la connexion puisse être réalisée quelle que soit l'orientation dudit récipient par rapport audit réceptacle.The conductors are arranged under the bottom of the container and the feelers protrude from the receptacle, this architecture allowing the connection to be made whatever the orientation of said container relative to said receptacle.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, l'ensemble comprenant les éléments thermoélectriques le capteur de température et les moyens de mémoire est moulé dans le fond du récipient.According to another additional characteristic of the device according to the invention, the assembly comprising the thermoelectric elements, the temperature sensor and the memory means is molded into the bottom of the container.
Selon un mode de réalisation particulier du dispositif selon l'invention, le réceptacle comporte supérieurement une platine électronique portant les moyens de connexion par contact, et qui est assujettie au reste du réceptacle par encliquetage en force, l'étanchéité entre ladite platine électronique et l'intérieur dudit réceptacle étant réalise au travers d'un joint torique sur lequel elle prend appui, et qui permet par ailleurs de l'immobiliser en coopération avec des moyens d'appui. Selon une caractéristique additionnelle du mode de réalisation particulier du dispositif selon l'invention, la platine électronique présente un ou plusieurs trous débouchant extérieurement au joint torique dans un espace ouvrant sur l'extérieur du réceptacle.According to a particular embodiment of the device according to the invention, the receptacle includes an electronic circuit board carrying the contact connection means, and which is subject to the rest of the receptacle by snap-fitting, the seal between said electronic circuit board and the interior of said receptacle being produced through an O-ring on which it is supported, and which moreover makes it possible to immobilize it in cooperation with support means. According to an additional characteristic of the particular embodiment of the device according to the invention, the electronic circuit board has one or more holes opening outwardly to the O-ring in a space opening onto the outside of the receptacle.
Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé :In the attached drawing:
La figure 1 représente une vue schématique en éclaté et en coupe selon un plan vertical du dispositif électronique pour porter un élément liquide ou solide à une température donnée selon l'invention.FIG. 1 represents a schematic exploded view in section along a vertical plane of the electronic device for bringing a liquid or solid element to a given temperature according to the invention.
La figure 2 représente une vue schématique de dessous d'une partie du même dispositif.Figure 2 shows a schematic view from below of part of the same device.
La figure 3 représente une vue partielle et en coupe d'une autre partie du même dispositif.Figure 3 shows a partial sectional view of another part of the same device.
En référence à la figure 1, on peut voir qu'un dispositif électronique pour porter un élément liquide ou solide à une température donnée selon l'invention comporte deux parties, à savoir un récipient 1 et un réceptacle 2 destiné à recevoir le récipient 1.With reference to FIG. 1, it can be seen that an electronic device for bringing a liquid or solid element to a given temperature according to the invention has two parts, namely a container 1 and a receptacle 2 intended to receive the container 1.
On notera que des raisons de commodité la description qui suit fait référence à la mise en température d'un élément liquide, sachant que le dispositif selon l'invention peut également être utilisé pour traiter des éléments solides. Le récipient 1 peut présenter différentes formes, par exemple celle d'une bouteille, peut être réalisé dans un matériau tel qu'un copolymère de type « Duras ar ».It will be noted that, for reasons of convenience, the description which follows refers to the heating up of a liquid element, knowing that the device according to the invention can also be used to treat solid elements. The container 1 can have different shapes, for example that of a bottle, can be made of a material such as a “Duras ar” type copolymer.
Le récipient 1 comprend une paroi 10 et un fond 11 dans lequel est moulé un insert 3 comprenant un ensemble 30 de composants électroniques .The container 1 comprises a wall 10 and a bottom 11 in which is molded an insert 3 comprising a set 30 of electronic components.
L' insert 3 comporte ainsi un ou plusieurs éléments thermoélectriques 31 de type modules à effet Peltier, aptes à transmettre des calories ou des frigories au liquide destiné à être contenu dans le récipient 1, un capteur de température 32, ainsi que des moyens de mémoire 33.The insert 3 thus comprises one or more thermoelectric elements 31 of the Peltier effect module type, capable of transmitting calories or frigories to the liquid intended to be contained in the container 1, a temperature sensor 32, as well as memory means. 33.
Le réceptacle 2 se présente sous la forme d'un boîtier renfermant un moyen 20 de production ou de transformation d'énergie électrique, qui peut consister en une batterie ou en un transformateur relié au secteur.The receptacle 2 is in the form of a box containing a means 20 for producing or transforming electrical energy, which may consist of a battery or of a transformer connected to the mains.
Le récipient 1 est de forme sensiblement cylindrique et son fondThe container 1 is of substantially cylindrical shape and its bottom
11 est rond, tandis que le réceptacle 2 présente supérieurement un logement 21 de forme complémentaire permettant d'accueillir étroitement la base du récipient 1.11 is round, while the receptacle 2 has a recess 21 of complementary shape which allows the base of the container 1 to be received closely.
Le réceptacle 2 comporte supérieurement une platine électronique 22 alimentée par le moyen 20 de production ou de transformation d'énergie électrique, et sur la face supérieure 23 de laquelle sont disposés des moyens 24 de connexion au récipient 1.The receptacle 2 includes an electronic circuit board 22 supplied by the means 20 for producing or transforming electrical energy, and on the upper face 23 of which are arranged means 24 for connection to the container 1.
Les moyens de connexions 24 consistent en des palpeurs à ressort, en l'occurrence au nombre de quatre, destinés à coopérer avec des éléments conducteurs disposés sur la face inférieure 12 du fond 11 du récipient 1.The connection means 24 consist of spring probes, in this case four in number, intended to cooperate with conductive elements arranged on the lower face 12 of the bottom 11 of the container 1.
En référence à la figure 2, on peut voir cette face inférieureReferring to Figure 2, we can see this underside
12 où les éléments conducteurs se présentent sous la forme de pistes 13 rondes concentriques à un plot conducteur central 14, tandis que les palpeurs 24 sont répartis en sorte de coïncider chacun avec une piste 13, et avec le plot 13 pour le palpeur 24 central, dans le mode de réalisation représenté les palpeurs 24 sont alignés selon un rayon.12 where the conductive elements are in the form of tracks 13 round concentric with a central conductive pad 14, while the feelers 24 are distributed so as to coincide each with a track 13, and with the stud 13 for the central feeler 24, in the embodiment shown the feelers 24 are aligned along a radius.
Cette architecture permet d'assurer la connexion sans avoir à se préoccuper du positionnement, du point vue angulaire, du récipient 1 par rapport au réceptacle 2.This architecture ensures the connection without having to worry about the positioning, from an angular point of view, of the container 1 relative to the receptacle 2.
En référence maintenant à la figure 3, on peut voir que le logement 21 destiné à accueillir la base du récipient 1 est délimi é par un rebord périphérique 25 présentant du côté interne au logement 21 une paroi 26 inclinée en sorte de permettre le guidage et le centrage du récipient 1.Referring now to FIG. 3, it can be seen that the housing 21 intended to receive the base of the container 1 is delimited by a peripheral rim 25 having on the internal side of the housing 21 a wall 26 inclined so as to allow the guidance and the centering the container 1.
On notera que la platine électronique 22 est assujettie au reste du réceptacle 2 par encliquetage en force, l'étanchéité entre la platine électronique 22 et l'intérieur du réceptacle étant réalisé au travers d'un joint torique J sur lequel elle prend appui, et qui permet par ailleurs de l'immobiliser en coopération avec des moyens d' appui tels que des pions non visibles, permettant de la contraindre par le dessus.It will be noted that the electronic circuit board 22 is subject to the rest of the receptacle 2 by force snap-fastening, the seal between the electronic circuit board 22 and the interior of the receptacle being produced through an O-ring J on which it is supported, and which also makes it possible to immobilize it in cooperation with support means such as non-visible pins, making it possible to constrain it from above.
La platine électronique 22 présente un trou 27 s' ouvrant intérieurement au rebord 25, et débouchant extérieurement au joint torique J dans un espace 28 pourvu d'un écoulement 29 débouchant sur .l'extérieur du réceptacle 2. Cette configuration permet de pallier les risques de débordement, et d'éviter l'introduction de liquide à l'intérieur du réceptacle 2.The electronic circuit board 22 has a hole 27 opening internally at the rim 25, and opening externally to the O-ring J in a space 28 provided with a flow 29 opening onto the outside of the receptacle 2. This configuration makes it possible to mitigate the risks overflow, and to avoid the introduction of liquid inside the receptacle 2.
En pratique, on place le récipient 1 sur le réceptacle 2, puis on programme sur le réceptacle 2, qui comporte à cet effet des moyens d' affichage et de programmation connus en soi non représentés, la valeur de la température à laquelle on souhaite amener le liquide contenu dans le récipient. Cette température est transférée aux moyens de mémoire 33 qui la stockent. Tant que le capteur de température 32 n'enregistre pas une valeur égale à celle voulue, le ou les éléments thermoélectriques 31 sont alimentés pour produire des calories ou des frigories.In practice, the container 1 is placed on the receptacle 2, then programs on the receptacle 2, which comprises for this purpose display and programming means known per se not shown, the value of the temperature to which it is desired to bring the liquid in the container. This temperature is transferred to the memory means 33 which store it. As long as the temperature sensor 32 does not register a value equal to that desired, the thermoelectric element or elements 31 are supplied to produce calories or frigories.
On notera qu'il est possible de prévoir la mémorisation de deux températures, une température d'exploitation et une température de consigne proche de celle d'exploitation. En pratique le liquide est amené et maintenu à la température de consigne, et avant utilisation il est amené rapidement à la température d'exploitation par manipulation des moyens de programmation du réceptacle 2.Note that it is possible to provide for the storage of two temperatures, an operating temperature and a set temperature close to that of operation. In practice, the liquid is brought and maintained at the set temperature, and before use it is brought quickly to the operating temperature by manipulation of the programming means of the receptacle 2.
Ce procédé permet une économie d'une part d'énergie lorsque le moment auquel le liquide doit être utilisé n'est pas parfaitement défini, et également de produit si par exemple la température d'exploitation est celle d'ébullition et donc d'évaporation.This process allows a saving of a part of energy when the time at which the liquid must be used is not perfectly defined, and also of product if for example the operating temperature is that of boiling and therefore of evaporation .
On peut également prévoir de programmer différents cycles de chauffe, d'une durée prédéterminée en fonction d'une utilisation cyclique. A titre d'exemple, un tel dispositif peut trouver une application particulière auprès d'un pâtissier utilisant une préparation chaude tel que du chocolat. Le chocolat peut être maintenu à une certaine température puis amené de manière cyclique, selon les pâtisseries à réaliser, à une température plus élevée d'utilisation.It is also possible to program different heating cycles, of a predetermined duration as a function of cyclic use. For example, such a device can find a particular application with a pastry chef using a hot preparation such as chocolate. The chocolate can be kept at a certain temperature and then brought cyclically, depending on the pastries to be produced, to a higher temperature of use.
Le réceptacle 2 comporte bien évidemment des moyens d'affichage permettant la visualisation des différentes phases par lesquelles passe le liquide.The receptacle 2 obviously includes display means allowing the visualization of the different phases through which the liquid passes.
Le fait que la ou les températures soient mémorisées au niveau du récipient 1, permet avantageusement d'utiliser plusieurs récipients 1 avec un seul réceptacle 2, ou bien de programmer un récipient 1 sur un réceptacle 2 et de l'apparier à un autre réceptacle 2.The fact that the temperature or temperatures are stored at the level of the container 1, advantageously makes it possible to use several containers 1 with a single receptacle 2, or else to program a container 1 on a receptacle 2 and to match it to another receptacle 2.
Le dispositif selon l'invention trouve de nombreuses applications, que ce soit dans le secteur professionnel ou grand public de l'alimentaire pour la préparation de boissons froides, chaudes tels que des cocktails flambés par exemple, de sauces ou analogues, mais également dans le domaine de l'industrie dans les laboratoires chimiques ou d'analyse. The device according to the invention finds numerous applications, whether in the professional or general public sector of the food industry for the preparation of cold, hot drinks such as flambé cocktails for example, sauces or the like, but also in the industry field in chemical or analytical laboratories.
