Abstract

The rotary percolator is for the automatic infusion of coffee, having only one moving part. This comprises a plate turning on its lengthwise axis via a shaft, to which it is fixed. This can have a transverse recess whose volume corresponds to the quantity of coffee for each infusion, and formed in a spherical portion. A filter is fixed at the bottom of the recess, and beyond this is an oblique passage allowing the coffee to flow out of the spherical portion. The component can be hollow, filled with water heated by a resistance element (5).

Description

L'objet de l'invention concerne un dispositif pour machine a infusion de café permettant d'effectuer automatiquement le remplissage de la mouture, l'infusion du café et la vidange du marc par une simple rotation du groupe chaudière. The object of the invention relates to a device for a coffee brewing machine making it possible to automatically fill the ground coffee, brew coffee and drain the grounds by a simple rotation of the boiler group.

Dans les dispositifs connus de machines a café automatique, les opérations de remplissage, d'infusion et de vidange sont effectués par des mécanismes complexes tels que : verins, piston, bielles, ressorts, coulisseaux etc,.. qui sont encombrants, d'une réalisation difficile et chers.. D' autre part, toutes ces pièces, étant lourdes, absorbent beaucoup de calories et les premiers cafés sont froids. In the known devices of automatic coffee machines, the filling, infusion and emptying operations are carried out by complex mechanisms such as: cylinders, piston, connecting rods, springs, slides, etc., which are bulky, of a difficult and expensive production. On the other hand, all these pieces, being heavy, absorb a lot of calories and the first coffees are cold.

Le dispositif suivant l'invention supprime ces inconvénients et permet la réalisation de machines A café très simples, compactes , économiques et dont tous les cafés dès le premier sortent chauds. The device according to the invention eliminates these drawbacks and allows the production of very simple, compact, economical coffee machines from which all coffees come out hot.

Il est constitué par une pièce creuse terminée par une portion de sphère percée d'un trou servant de récep- tacle a la mouture ; il est mis en communication par rotation de la sphère successivement avec 3 autres orifices servant au remplissage, a l'infusion et a la vidange du marc. Cette pièce qui est creuse sert en meule temps de corps de chauffage ce qui mainttent toute la masse de métal a la bonne température et permet au café d'être toujours chaud dès la première tasse. It consists of a hollow part ending in a portion of a sphere pierced with a hole serving as a receptacle for grinding; it is placed in communication by rotation of the sphere successively with 3 other orifices used for filling, infusion and emptying of the grounds. This hollow part is used as a heating body for a period of time which keeps the whole mass of metal at the right temperature and allows the coffee to be always hot from the first cup.

Sur les dessins annexés donnes a titre d'exemple non limitatifs d'une des formes de réalisation de l'objet de l'invention :
La Figure 1 ressente vue en coupe transversale le groupe infuseur en position chargement.In the appended drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention:
Figure 1 shows a cross-sectional view of the brew group in the loading position.

La Figure 2 montre le groupe infuseur en position infusion et la figure 3 en position vidange du marc.  Figure 2 shows the infuser group in the infusion position and Figure 3 in the coffee grounds emptying position.

La Figure 4 représente vu en coupe longitudinale 1' ensemble du groupe infuseur. Figure 4 shows a longitudinal section view of the entire infuser group.

Le dispositif est constitué par un carter 1 dans lequel est logée la partie sphérique 2 DU groupe infuseur 3 qui est creux et rempli dfeau 4 laquelle est chauffée par une résistance 5. The device consists of a casing 1 in which is housed the spherical part 2 OF the infuser group 3 which is hollow and filled with water 4 which is heated by a resistor 5.

La tartie sphérique du groupe 2 comporte une cavité 6 dont le fond est muni d'unfiltre 7 . Le volume de la cavité 6 détermine la quantité de mouture admise. The spherical tartie of group 2 comprises a cavity 6, the bottom of which is provided with a filter 7. The volume of the cavity 6 determines the quantity of ground coffee allowed.

Un arbre de commande 8 manoeuvré manuellement ou mO- caniquement permet de faire tourner le groupe infuseur 3 dont la partie sphérique 2 tournant dans le carter 7 amène la cavité 6 en communication avec une trémie 9 contenant la mouture de café qui remplit alors la cavité 6.  A control shaft 8 operated manually or mechanically makes it possible to rotate the brewing group 3, the spherical part 2 of which turns in the casing 7 brings the cavity 6 into communication with a hopper 9 containing the coffee grounds which then fill the cavity 6 .

En faisant tourner de 90- le groupe infuseur la cavité 6 se déplace et vient se positionner en face de orifice 10 pour l'injection d'eau chaude 4 provenant de la chaudière 3 par l'intermédiaire d'un tuyau souple, ou alors rigide en utilisant une prise d'eau sur la partie cylindrique du groupe avec 2 j oints tournants 12. By rotating 90- the infuser group the cavity 6 moves and is positioned opposite the orifice 10 for the injection of hot water 4 from the boiler 3 via a flexible pipe, or then rigid using a water intake on the cylindrical part of the group with 2 rotary joints 12.

L'eau chaude est injectée en 10 à travers une grille de répartition 11 dans la cavité 6 pleine de mouture.  The hot water is injected at 10 through a distribution grid 11 into the cavity 6 full of ground coffee.

Le café sortant du filtre 7 s'écoule par un conduit oblique 13 qui se continue A.travers le carter, jusqu'à la tasse 14. The coffee leaving the filter 7 flows through an oblique conduit 13 which continues through the casing, up to the cup 14.

Pour équilibrer la poussée due a l'injection d'eau en 10, il est nécessaire d'injecter de l'eau a la mEme pression à l'opposé de la sphère en 15 en reliant par une conduite les 2 orifices 70 et 15. To balance the thrust due to the injection of water at 10, it is necessary to inject water at the same pressure opposite the sphere at 15 by connecting the 2 orifices 70 and 15 by a pipe.

En faisant tourner à nouveau de 90- dans le mOme sens le groupe infuseur la cavité 6 est mise en commanication avec ltorifi^e 16 servant a la vidange du marc contenu dans la cavité 6. Un gicleur 17 situé dans l'axe de l'orifice 16 permet d'envoyer de l'eau chaude sous pression qui va nettoyer la cavité 6 ainsi que le filtre 7.  By turning again 90- in the same direction the infuser group the cavity 6 is put in commanication with ltorifi ^ e 16 used for the emptying of the marc contained in the cavity 6. A nozzle 17 located in the axis of the orifice 16 makes it possible to send pressurized hot water which will clean the cavity 6 as well as the filter 7.

Une nouvelle rotation de 1800 du groupe infuseur 3 le ramenera à sa position de départ, c'est à dire la cavité 6 en face de la trémie 9 pour un nouveau chargement. A further rotation of 1800 of the infuser group 3 will bring it back to its starting position, that is to say the cavity 6 in front of the hopper 9 for a new loading.

L' étanchéité entre la cavité 6 de la partie sphérique 2 et les orifices du carter 1 est assurée par 4 joints toriques 18 disposés autour des orifices 9,10 ,16 et 15. The seal between the cavity 6 of the spherical part 2 and the orifices of the casing 1 is ensured by 4 O-rings 18 arranged around the orifices 9, 10, 16 and 15.

Ces 4 joints servent en même temps de palier pour la rotation du groupe infuseur 3 dans le carter 1 ce qui conduit À un fonctionnement silencieux et très souple.These 4 seals serve at the same time as a bearing for the rotation of the infuser group 3 in the casing 1, which leads to silent and very flexible operation.

Un orifice 20 situé dans le carter permet d'injecter de l'eau chaude sur le sommet de la partie spherique 2 apurés chaque utilisation pour la rincer et eviter son encrassement. Les eaux de rinçage s'évacuent par un orifico 21 situé a la partie inférieure du carter 1. An orifice 20 located in the casing makes it possible to inject hot water on the top of the spherical part 2, cleared each use, to rinse it and avoid its fouling. The rinsing water is discharged through an orifice 21 located at the bottom of the casing 1.

Pour éviter que les eaux de rinçage ne s'écoulent en dehors de l'orifice 21. I1 est necessaire d'assurer.l'étan- chéité sur l'arbre 8 avec un joint torique 19 et sur l'autre coté avec les joints toriques 12.  To prevent the rinsing water from flowing out of the orifice 21. It is necessary to ensure the seal on the shaft 8 with an O-ring 19 and on the other side with the seals toric 12.
