Description
La présente invention concerne un dispositif de production de boissons parThe present invention relates to a device for producing beverages
infusion d'eau chaude.infusion of hot water.
L'invention s'appliquera notamment à des machines à café permettant la production de café liquide à partir de café moulu, par exemple mais non 5 limitativement conditionné dans des doses individuelles. The invention will particularly apply to coffee machines for the production of liquid coffee from ground coffee, for example but not limited to conditioning in individual doses.
Plus précisément, l'invention est apte à s'inscrire dans le cadre de machines à café expresso. More specifically, the invention is able to fit in the context of espresso coffee machines.
Cette utilisation n'est pas limitative et, notamment, on pourra réaliser des boissons par infusion d'autres matières. This use is not limiting and, in particular, drinks can be made by infusion of other materials.
io Un dispositif de production de boissons par infusion présente généralement un circuit d'eau passant par une chaudière de sorte à porter l'eau à température d'infusion (par exemple autour de 100 C), une pompe pour opérer une extraction de la matière à infuser sous pression et une chambre d'infusion aiu sein de laquelle la matière à infuser est placée et au travers de laquelle circule l'eau chaude sous pression. A beverage production device by infusion generally has a circuit of water passing through a boiler so as to bring the water to infusion temperature (for example around 100 C), a pump to operate an extraction of the material. to infuse under pressure and an infusion chamber in which the material to infuse is placed and through which circulates hot water under pressure.
Généralement, au moins une partie de la chambre d'infusion est portée par un groupe d'extraction permettant par exemple d'opérer les phases d'ouverture et de fermeture de la chambre d'infusion, phases nécessaires à l'admission de la matière à infuser, à la fermeture étanche de la chambre et à l'évacuation de la matière infusée. Generally, at least a portion of the infusion chamber is carried by an extraction unit allowing for example to operate the opening and closing phases of the infusion chamber, phases necessary for the admission of the material infusing, sealing the chamber and evacuating the infused material.
Dans certains cas, on a pensé à monter le groupe d'extraction de façon solidaire sur la chaudière. In some cases, it was thought to mount the extraction unit integrally on the boiler.
On forme ainsi un ensemble compact et on limite la longueur du circuit d'eau chaude. This forms a compact assembly and limits the length of the hot water circuit.
De façon classique, la fixation solidaire de la chaudière et du groupe d'extraction s'opère par encastrement du type vissage ou boulonnage. In conventional manner, the fixed fastening of the boiler and the extraction unit is effected by embedding of the screwing or bolting type.
De tels moyens de fixation ont l'inconvénient de rendre peu pratique le montage et le démontage. Such fastening means have the disadvantage of making impractical assembly and disassembly.
Cela est dommageable lors de la fabrication du dispositif mais aussi 30 lors de phases de maintenance ultérieures durant lesquelles il est probable que le groupe d'extraction de la chaudière doit être démonté. This is detrimental in the manufacture of the device but also in subsequent maintenance phases during which it is likely that the extraction unit of the boiler must be disassembled.
La présente invention permet de remédier aux inconvénients des dispositifs connus jusqu'à présent. Elle présente pour ce faire un dispositif de production de boissons par infusion d'eau chaude, doté d'un moyen de fixation du groupe d'extraction sur la chaudière amélioré. The present invention overcomes the disadvantages of the devices known hitherto. It has for this purpose a device for producing drinks by infusion of hot water, provided with a fixing means of the extraction unit on the improved boiler.
A cet effet, les moyens de fixation proposés par l'invention, exploite une coopération de rainures et de protubérances aptes à permettre un encastrement de grande efficacité tout en autorisant un démontage et un remontage aisés. For this purpose, the fastening means proposed by the invention, operates a cooperation grooves and protuberances capable of allowing a recess of high efficiency while allowing easy disassembly and reassembly.
Suivant un mode préféré de réalisation de l'invention, l'insertion des protubérances dans les logements rainurés s'opère par rotation relative de la chaudière et du groupe d'extraction. According to a preferred embodiment of the invention, the insertion of the protuberances in the grooved housing is effected by relative rotation of the boiler and the extraction unit.
to Cornpte tenu de la configuration sensiblement axiale généralement présente entre la chaudière et le groupe d'extraction, ce montage par rotation est particulièrement efficace. In view of the substantially axial configuration generally present between the boiler and the extraction unit, this rotational assembly is particularly effective.
D'autres buts et avantages apparaîtront au cours de la description qui suit d'un mode de réalisation préféré de l'invention qui n'est cependant pas 15 limitatif. Other objects and advantages will become apparent from the following description of a preferred embodiment of the invention, which is however not limiting.
La présente invention concerne un dispositif de production de boissons par infusion d'eau chaude, comportant un groupe d'extraction portant au moins une portion d'une chambre d'infusion et une chaudière, ledit groupe d'extraction étant monté sur la chaudière par des moyens de fixation, caractérisé par le fait que les moyens de fixation comprennent au moins un logement rainuré dans lequel s'insère une protubérance, ledit logement et la dite protubérance étant formés en vis-à-vis sur la chaudière et le groupe d'extraction. The present invention relates to a device for producing drinks by infusion of hot water, comprising an extraction unit carrying at least a portion of an infusion chamber and a boiler, said extraction unit being mounted on the boiler by fastening means, characterized in that the fastening means comprise at least one grooved housing into which a protuberance is inserted, said housing and said protuberance being formed vis-à-vis the boiler and the group of extraction.
Suivant des variantes préférées mais non limitatives, ce dispositif est tel que: - les moyens de fixation sont configurés pour un montage par rotation relative de la chaudière et du groupe d'extraction. According to preferred but non-limiting variants, this device is such that: the fixing means are configured for relative rotation mounting of the boiler and the extraction unit.
- les moyens de fixation comportent deux paires logement /protubérance formées symétriquement de part et d'autre de l'axe de rotation de montage. - The fixing means comprise two housing / protrusion pairs formed symmetrically on either side of the mounting axis of rotation.
- les protubérances sont des plots pourvus d'un rebord circulaire apte à s'insérer dans une portion de rainure circulaire des logements. - The protuberances are pads provided with a circular rim adapted to be inserted into a circular groove portion of the housing.
- un circuit d'alimentation en eau chaude est formé entre la chaudière et le groupe d'extraction de façon symétrique autour de l'axe de rotation de montage. - A hot water supply circuit is formed between the boiler and the extraction unit symmetrically about the mounting axis of rotation.
Les dessins ci-joints sont donnés à titre d'exemples et ne sont pas limitatifs de l'invention. Ils représentent seulement un mode de réalisation de l'invention et permettront de la comprendre aisément. The accompanying drawings are given by way of example and are not limiting of the invention. They represent only one embodiment of the invention and will make it easy to understand.
La figure 1 montre un exemple de chaudière vue en perspective. Figure 1 shows an example of a boiler seen in perspective.
La figure 2 est une vue en perspective d'un groupe d'extraction. Figure 2 is a perspective view of an extraction group.
Les figures 3 et 4 montrent deux phases successives de montage du groupe d'extraction sur la chaudière par un mouvement de rotation. Figures 3 and 4 show two successive phases of assembly of the extraction unit on the boiler by a rotational movement.
On a représenté en figure 1 une chaudière 1 constituée de façon courante et comportant dans son volume interne un circuit de transfert de l'eau to et des moyens de chauffage de l'eau par exemple sous forme de résistance. There is shown in Figure 1 a boiler 1 consisting of a current and having in its internal volume a water transfer circuit to and water heating means for example in the form of resistance.
Dans le cas de l'invention, on réalise une face de montage 2 sur la chaudière 1 par laquelle sera rapportée le groupe d'extraction 3 dont un exemple est présenté en figure 2. In the case of the invention, a mounting face 2 is produced on the boiler 1, through which the extraction unit 3, an example of which is shown in FIG. 2, will be reported.
Sur la face de montage 2 illustrée en figure 1, une sortie d'eau chaude is d'un circuit 11 est présentée. On the mounting face 2 illustrated in Figure 1, a hot water outlet is a circuit 11 is shown.
Le circuit 11 est connecté à l'entrée de la chambre d'infusion pour l'alimenter lors de la phase d'extraction de la substance à infuser. The circuit 11 is connected to the inlet of the infusion chamber to feed it during the extraction phase of the substance to be infused.
Le groupe d'extraction 3 représenté en figure 2 comporte tout ou partie de la chambre d'infusion. The extraction unit 3 shown in Figure 2 comprises all or part of the brewing chamber.
Dans l'exemple illustré, la chambre d'infusion est composée d'une partie fixe 4 réalisée solidairement à la chaudière 1 sur la face de montage 2 sous forme d'une coupelle. In the illustrated example, the infusion chamber is composed of a fixed part 4 integrally formed with the boiler 1 on the mounting face 2 in the form of a cup.
La partie fixe 4 coopère de façon étanche avec une partie mobile 5 lorsque la chambre d'infusion est fermée. The fixed part 4 cooperates sealingly with a movable part 5 when the infusion chamber is closed.
La partie mobile 5 est portée par le groupe d'extraction 3 et ce groupe 3 comporte différents moyens d'actionnement qui ne sont pas l'objet de l'invention et qui permettent de réaliser des phases d'ouverture et de fermeture de la chambre d'infusion par des mouvements successifs de la partie mobile 5. The moving part 5 is carried by the extraction unit 3 and this group 3 comprises various actuating means which are not the subject of the invention and which make it possible to realize phases of opening and closing of the chamber infusion by successive movements of the movable portion 5.
L'ensemble ainsi représenté aux figures 1 et 2 de la chaudière 1 et du groupe d'extraction 3 permet en particulier l'insertion de dosettes contenant du café moulu, la fermeture de la chambre d'infusion puis l'éjection de la dosette usagée. The assembly thus represented in FIGS. 1 and 2 of the boiler 1 and the extraction unit 3 makes it possible in particular to insert pods containing ground coffee, to close the brewing chamber and then to eject the used pod. .
En figure 1, la face de montage 2 présente deux logements 7a, 7b comportant chacun une rainure intérieure 8a, 8b. In Figure 1, the mounting face 2 has two housings 7a, 7b each having an inner groove 8a, 8b.
Comme illustré et également visible aux figures 3 et 4, la rainure 8a, 8b des logements 7a, 7b comporte une portion sensiblement circulaire au fond du logement 8a, 8b. As illustrated and also visible in Figures 3 and 4, the groove 8a, 8b of the housing 7a, 7b comprises a substantially circular portion at the bottom of the housing 8a, 8b.
Les logements 7a, 7b sont ici formés de façon symétriques autour de la sortie du circuit 11 de la chaudière 1 et sont configurés pour permettre un montage du groupe d'extraction 3 par un mouvement de rotation relative du groupe 3 et de la chaudière 1. The housings 7a, 7b are here formed symmetrically around the output of the circuit 11 of the boiler 1 and are configured to allow mounting of the extraction unit 3 by a relative rotational movement of the group 3 and the boiler 1.
lo A cet effet, l'un des logements 7a est formé avec un passage central orienté vers le bas et l'autre logement 7b est formé avec un passage central orienté vers le haut tel que visible en figure 1. lo For this purpose, one of the housing 7a is formed with a central passage oriented downwards and the other housing 7b is formed with a central passage oriented upwards as visible in Figure 1.
Des protubérances sont réalisées sur le groupe d'extraction 3 en vis-àvis des logements 7a, 7b pour coopérer avec les rainures 8a, 8b. Protuberances are formed on the extraction unit 3 facing the housings 7a, 7b to cooperate with the grooves 8a, 8b.
Dans le cas illustré, les protubérances sont formées par deux plots 6a, 6b présentant un rebord circulaire apte à s'engager dans les rainures 8a, 8b. In the illustrated case, the protuberances are formed by two studs 6a, 6b having a circular flange adapted to engage in the grooves 8a, 8b.
On comprend aisément que pour le montage, il suffit de manipuler le groupe d'extraction 3, d'effectuer un léger pivot du groupe 3 suivant son axe longitudinal pour l'appliquer sur la face de montage 2. It is easy to understand that for assembly, it is sufficient to manipulate the extraction unit 3, to make a slight pivot of the group 3 along its longitudinal axis to apply it to the mounting face 2.
Ensuite, un mouvement du groupe d'extraction 3 dans le sens horaire assure l'insertion des rebords 10a, 10b des plots 6a, 6b dans les rainures 8a, 8b des logements 7a, 7b. Then, a movement of the extraction unit 3 in the clockwise direction ensures the insertion of the flanges 10a, 10b of the pads 6a, 6b in the grooves 8a, 8b of the housings 7a, 7b.
Dans cette configuration, le groupe d'extraction est parfaitement solidaire de la chaudière 1. In this configuration, the extraction unit is perfectly integral with the boiler 1.
Au démontage, les étapes inverses sont opérées. When disassembling, the reverse steps are performed.
Bien entendu, le cas illustré est indicatif. En particulier, on pourrait former les logements 7a, 7b sur le groupe d'extraction 3 et les plots 6a, 6b en correspondance sur la face de montage 2 de la chaudière 1. Of course, the illustrated case is indicative. In particular, the housings 7a, 7b could be formed on the extraction unit 3 and the pads 6a, 6b correspondingly to the mounting face 2 of the boiler 1.
De même, l'un des logements et l'un des plots peuvent être formés sur 30 la chaudière et un autre logement et un autre plot formé en correspondance sur le groupe 3. Similarly, one of the housings and one of the pads may be formed on the boiler and another housing and another pad formed correspondingly on the group 3.
Dans le cas représenté, on notera que, la moitié de la chambre d'infusion (partie fixe 4) étant réalisée sur la chaudière 1, aucune étanchéité additionnelle n'est systématiquement nécessaire pour le montage du groupe 3 sur la chaudière 1. In the case shown, it will be noted that, half of the infusion chamber (fixed part 4) being made on the boiler 1, no additional sealing is systematically necessary for mounting the group 3 on the boiler 1.
En effet, un joint périphérique formé sur la dosette de mouture de café peut remplir la fonction d'étanchéité. Indeed, a peripheral seal formed on the coffee grounds pod can fulfill the sealing function.
