TRAVAIL MUNI D'UN FILTRE WORK WITH FILTER
La présente invention se rapporte au domaine technique général des appareils électroménagers de préparation culinaire comportant un boîtier renfermant un moteur pour l'entraînement d'un outil rotatif dans le fond d'un récipient de travail et comprenant un filtre s'étendant autour de l'outil rotatif pour définir une barrière filtrante divisant le volume à l'intérieur du récipient entre un espace de mixage disposé à l'intérieur du filtre et un espace collecteur disposé à l'extérieur du filtre, et se rapporte plus particulièrement à un appareil électroménager de préparation culinaire dans lequel le récipient de travail comporte un poussoir pouvant être introduit dans l'espace de mixage par une ouverture supérieure du filtre. The present invention relates to the general technical field of electrical household appliances for culinary preparation comprising a housing enclosing a motor for driving a rotary tool in the bottom of a working container and comprising a filter extending around the rotary tool for defining a filtering barrier dividing the volume inside the container between a mixing space disposed inside the filter and a collecting space disposed outside the filter, and more particularly relates to a household appliance of culinary preparation in which the working container comprises a pusher which can be introduced into the mixing space through an upper opening of the filter.
Il est connu, du brevet US 6 135 019, un appareil de préparation culinaire comportant un récipient de travail renfermant un outil rotatif et comprenant un filtre s'étendant autour de l'outil rotatif pour définir une barrière filtrante entre un espace de mixage à l'intérieur du filtre et un espace collecteur à l'extérieur du filtre. Un tel appareil comporte également un poussoir pouvant être introduit à l'intérieur de l'espace de mixage afin d'exercer une pression sur les aliments solides disposés dans l'espace de mixage, tels que des fruits ou des légumes, pour amener ces aliments solides en direction de l'outil rotatif et faire du jus. Afin d'éviter que le poussoir ne vienne heurter l'outil rotatif, la course du poussoir est limitée par une butée qui vient stopper le poussoir dans une position basse dans laquelle l'extrémité inférieure du poussoir se trouve juste au-dessus de l'outil rotatif. It is known, from US Pat. No. 6,135,019, a food preparation apparatus comprising a working container enclosing a rotary tool and comprising a filter extending around the rotary tool to define a filtering barrier between a mixing space at the same time. inside the filter and a collecting space on the outside of the filter. Such an apparatus also comprises a pusher which can be introduced inside the mixing space in order to exert pressure on the solid foods placed in the mixing space, such as fruits or vegetables, to bring these foods solid in the direction of the rotary tool and make juice. In order to prevent the pusher from striking the rotary tool, the stroke of the pusher is limited by a stop which stops the pusher in a low position in which the lower end of the pusher is just above the pusher. rotary tool.
Un tel appareil présente l'avantage de permettre facilement la réalisation de jus de fruits ou de légumes, en plaçant les aliments dans le filtre et en mixant le tout avec un peu d'eau. Such an apparatus has the advantage of easily allowing the production of fruit or vegetable juices, by placing the food in the filter and mixing it all with a little water.
Cependant, un tel appareil présente l'inconvénient de ne pas permettre une récupération complète du jus présent dans l'espace de mixage.

Ces nervures 25 coopèrent avec les empreintes 45 pour immobiliser le filtre 4 en rotation et le bloquer axialement à une hauteur prédéterminée pour laquelle l'extrémité inférieure du filtre 4 se trouve intimement engagée dans une ouverture 26 présente dans le fond de l'enveloppe 20 du récipient 2 de sorte qu'une liaison sensiblement étanche est réalisée entre l'extrémité inférieure du filtre 4 et le fond du récipient 2. The lower end of the filter 4 has an outer peripheral surface provided with cavities 45 into which are engaged ribs 25, visible in FIGS. 5 and 6, projecting near the bottom of the receptacle 2. These ribs 25 cooperate with the cavities 45 to immobilize the filter 4 in rotation and to lock it axially at a predetermined height for which the lower end of the filter 4 is intimately engaged in an opening 26 present in the bottom of the casing 20 of the container 2 so that a substantially sealed connection is made between the lower end of the filter 4 and the bottom of the container 2.
Le corps 40 du filtre 4 comporte également un épaulement 46, à proximité de son extrémité supérieure, dont le diamètre intérieur correspond au diamètre de l'ouverture 50 du couvercle 5, cet épaulement 46 se prolongeant par une bague 47 adaptée pour traverser l'ouverture 50 du couvercle 5 et faire saillie à l'extérieur du récipient 2. The body 40 of the filter 4 also comprises a shoulder 46, close to its upper end, whose inner diameter corresponds to the diameter of the opening 50 of the lid 5, this shoulder 46 extending by a ring 47 adapted to pass through the opening 50 of the cover 5 and protrude outside the container 2.
De manière avantageuse, la bague 47 est constituée par une pièce qui est rapportée par collage sur le corps 40 du filtre, la bague 47 comportant une ouverture supérieure 47A et une extrémité inférieure munie d'une nervure 48 circulaire faisant saillie vers l'intérieur de la bague 47, cette nervure 48 comportant localement deux fentes 48A obliques, disposées à 180° l'une de l'autre, chaque fentes 48A étant bordée par une rampe de guidage 48B. Advantageously, the ring 47 is constituted by a piece which is attached by gluing to the body 40 of the filter, the ring 47 having an upper opening 47A and a lower end provided with a circular rib 48 projecting towards the inside of the body. the ring 47, this rib 48 locally having two oblique slots 48A, arranged at 180 ° from each other, each slot 48A being bordered by a guide ramp 48B.
La bague 47 comporte également deux renfoncements 49, disposés à 180° l'un de l'autre et au dessus de la nervure 48, chaque renfoncement 49 comportant un bossage 49A faisant saillie vers l'intérieur de la bague 47. The ring 47 also comprises two recesses 49, arranged at 180 ° one on the other and above the rib 48, each recess 49 having a boss 49A projecting inwardly of the ring 47.
Conformément aux figures 4 à 6, le récipient 2 reçoit un poussoir 6 destiné à être introduit dans l'espace de mixage du filtre 4 pour y être déplacé en direction du fond du récipient 2 jusqu'à une position basse, le poussoir 6 comportant un corps 60 cylindrique adapté pour s'insérer librement dans le corps 40 cylindrique du filtre 4 et présentant une collerette 61 à son extrémité supérieure. According to FIGS. 4 to 6, the container 2 receives a pusher 6 intended to be introduced into the mixing space of the filter 4 in order to be moved towards the bottom of the container 2 to a low position, the pusher 6 comprising a 60 cylindrical body adapted to fit freely into the cylindrical body 40 of the filter 4 and having a flange 61 at its upper end.
De manière préférentielle, le corps 60 du poussoir présente une forme complémentaire du corps 40 du filtre de sorte que le poussoir 6 occupe pratiquement tout l'espace de mixage à l'intérieur du filtre 4 lorsqu'il se trouve en position basse dans le filtre 4. Preferably, the body 60 of the pusher has a complementary shape of the body 40 of the filter so that the pusher 6 occupies substantially all the mixing space inside the filter 4 when it is in the lower position in the filter 4.
A titre d'exemple, le poussoir 6 est réalisé par moulage dans un matériau plastique, tel que du polypropylène, et le corps 60 cylindrique du poussoir présente un diamètre extérieur inférieur de l'ordre de 0.2 à 0.5 mm au diamètre intérieur du corps 40 cylindrique du filtre 4 au niveau de sa moitié inférieure. De cette manière, le poussoir 6 peut coulisser librement dans le filtre 4 et seul un faible jeu résulte entre le poussoir 6 et le filtre 4. For example, the pusher 6 is made by molding in a plastic material, such as polypropylene, and the cylindrical body 60 of the pusher has a lower outside diameter of the order of 0.2 to 0.5 mm to the inside diameter of the body 40 cylindrical filter 4 at its lower half. In this way, the pusher 6 can slide freely in the filter 4 and only a small clearance results between the pusher 6 and the filter 4.
Plus particulièrement selon l'invention, le poussoir 6 comprend une extrémité inférieure comportant une cavité 7 dans laquelle l'outil rotatif 3 vient s'insérer lorsque le poussoir 6 est en position basse. More particularly according to the invention, the pusher 6 comprises a lower end having a cavity 7 in which the rotary tool 3 is inserted when the pusher 6 is in the low position.
Conformément à la figure 4, la cavité 7 est délimitée latéralement par une paroi périphérique 62 cylindrique appartenant au corps 60 cylindrique du poussoir et comporte un fond 63 de forme tronconique faisant saillie vers l'intérieur de la cavité 7. According to FIG. 4, the cavity 7 is delimited laterally by a cylindrical peripheral wall 62 belonging to the cylindrical body 60 of the pusher and comprises a frustoconical bottom 63 projecting towards the inside of the cavity 7.
Dans le mode de réalisation particulier illustré, la cavité 7 présente une profondeur de l'ordre de 2 cm au niveau de la paroi périphérique 62 et l'inclinaison de la partie conique du fond 63 épouse l'inclinaison de la lame supérieure de l'outil rotatif 3 de sorte que le fond 63 du poussoir vient au plus près de l'outil rotatif sans rentrer en contact avec celui-ci lorsque le poussoir 6 est amené en position basse. De manière préférentielle, la surface externe du corps 60 cylindrique comporte deux nervures de guidage 64 disposées à 180° l'une de l'autre, ces nervures de guidage 64 s'étendant sur toute la moitié supérieure du poussoir 6 selon un parcours hélicoïdal et étant destinées à venir s'insérer dans les fentes 48A du filtre 4 pour former avec ces dernières des moyens de guidages assurant un déplacement du poussoir 6 dans le filtre 4 selon un mouvement combiné de translation axiale et de rotation. In the particular embodiment illustrated, the cavity 7 has a depth of about 2 cm at the peripheral wall 62 and the inclination of the conical portion of the bottom 63 matches the inclination of the upper blade of the rotary tool 3 so that the bottom 63 of the pusher comes closest to the rotary tool without coming into contact with it when the pusher 6 is brought into the low position. Preferably, the outer surface of the cylindrical body 60 comprises two guide ribs 64 arranged at 180 ° to one another, these guide ribs 64 extending over the entire upper half of the pusher 6 along a helical path and being intended to be inserted into the slots 48A of the filter 4 to form with the latter guide means ensuring a displacement of the pusher 6 in the filter 4 according to a combined movement of axial translation and rotation.
Le fonctionnement de l'appareil électroménager et son procédé d'utilisation vont maintenant être décrits en relation avec les figures 5 et 6. Lorsque l'utilisateur souhaite réaliser un jus de fruits ou de légumes, il insère le filtre 4 dans le récipient 2 en alignant les découpes 44A du filtre avec les renflements 24 du récipient de manière à effectuer un pré-positionnement du filtre 4 par rapport au récipient 2. The operation of the appliance and its method of use will now be described in connection with FIGS. 5 and 6. When the user wishes to produce a fruit or vegetable juice, he inserts the filter 4 into the container 2 in aligning the cutouts 44A of the filter with the bulges 24 of the container so as to pre-position the filter 4 relative to the container 2.
L'utilisateur pousse ensuite verticalement sur le filtre 4 jusqu'à ce que les empreintes 45, présentes à la base du filtre 4, soient engagées sur les nervures 25 du récipient. Le couvercle 5 doit alors être disposé sur le filtre 4, pour réduire les risques d'éclaboussures et maintenir le filtre 4 en position de travail, et les aliments peuvent être introduits dans l'espace de mixage du filtre par l'ouverture 50 du couvercle, de l'eau devant également être ajoutée pour diluer le jus. The user then pushes vertically on the filter 4 until the cavities 45, present at the base of the filter 4, are engaged on the ribs 25 of the container. The lid 5 must then be placed on the filter 4, to reduce the risk of splashing and keep the filter 4 in the working position, and the food can be introduced into the mixing space of the filter through the opening 50 of the lid , water must also be added to dilute the juice.
Le poussoir 6 est alors engagé dans le filtre 4 dans une position haute d'attente, illustrée sur la figure 5, dans laquelle l'extrémité inférieure des nervures 64 de guidage se trouve en regard des fentes de guidage 48A, le poussoir 6 se trouvant immobilisé dans cette position par l'engagement des bossages 49A du filtre 4 dans une rainure 64A ménagée sur les nervures de guidage 64, ou en faisant reposer l'extrémité inférieure des nervures 64 sur la nervure 48. The pusher 6 is then engaged in the filter 4 in a high standby position, illustrated in FIG. 5, in which the lower end of the guide ribs 64 is opposite the guide slots 48A, the pusher 6 being located immobilized in this position by the engagement of the bosses 49A of the filter 4 in a groove 64A formed on the guide ribs 64, or by resting the lower end of the ribs 64 on the rib 48.
L'utilisateur peut alors faire fonctionner le moteur de l'appareil de manière à ce que les fruits soient broyés par l'outil rotatif 3, le jus qui en résulte se diffusant en grande partie, par l'effet de la force centrifuge, au travers des grilles de filtration 42 du filtre 4 et étant recueilli dans l'espace collecteur à extérieur du filtre 4. Durant cette phase de mixage, le poussoir 6 disposé en position haute présente l'avantage d'empêcher la remontée de jus par l'ouverture 50 du couvercle 5. The user can then operate the motor of the apparatus so that the fruits are crushed by the rotary tool 3, the resulting juice being largely diffused, by the effect of the centrifugal force, to the through filtration grids 42 of the filter 4 and being collected in the collector space outside the filter 4. During this mixing phase, the pusher 6 disposed in the up position has the advantage of preventing the rise of juice through the opening 50 of the lid 5.
Lorsque les aliments présents dans l'espace de mixage sont totalement mixés, l'utilisateur peut arrêter le moteur de l'appareil puis appuyer légèrement sur le poussoir 6 en le faisant tourner dans le sens horaire de manière à générer un déplacement en translation du poussoir 6 vers le fond du récipient 2. When the food present in the mixing space are totally mixed, the user can stop the motor of the appliance and then lightly press on the pusher 6 by turning it clockwise so as to generate a movement in translation of the pusher 6 towards the bottom of the container 2.
Cette descente du poussoir 6 s'effectue jusqu'à la position basse, illustrée sur la figure 6, dans laquelle la collerette 61 du poussoir se retrouve en butée contre la bague 47 du filtre 4 et l'outil rotatif 3 se trouve introduit en grande partie dans la cavité 7 à l'extrémité inférieure du poussoir 6. This descent of the pusher 6 is carried out to the lower position, illustrated in FIG. 6, in which the flange 61 of the pusher abuts against the ring 47 of the filter 4 and the rotary tool 3 is introduced in large part. part in the cavity 7 at the lower end of the pusher 6.
Lors de cette descente du poussoir 6 au sein de l'espace de mixage, le poussoir 6 agit tel un piston et exerce une pression sur le jus présent dans l'espace de mixage de sorte que le jus est chassé vers l'espace collecteur en passant par les grilles de filtration 42 du filtre 4. En particulier, la cavité 7 présente à l'extrémité du poussoir forme une poche d'air qui repousse le jus présent autour de l'outil rotatif 3 lorsque le poussoir est amené dans la position basse, le léger jeu résultant entre le poussoir 6 et le filtre 4 permettant au jus présent dans le fond du récipient de remonter le long du filtre 4 et de s'échapper au travers des grilles de filtration 42 vers l'espace collecteur. De cette manière, la quasi-intégralité du jus généré par le mixage est recueillie dans l'espace collecteur. During this descent of the pusher 6 within the mixing space, the pusher 6 acts like a piston and exerts a pressure on the juice present in the mixing space so that the juice is driven to the collecting space. passing through the filtering grids 42 of the filter 4. In particular, the cavity 7 present at the end of the pusher forms a pocket of air which pushes the juice present around the rotary tool 3 when the pusher is brought into the position low, the slight clearance resulting between the pusher 6 and the filter 4 allowing the juice present in the bottom of the container to go up along the filter 4 and to escape through the filter grids 42 to the collecting space. In this way, almost all the juice generated by the mix is collected in the collecting space.
Un appareil de préparation culinaire muni d'un tel poussoir présente donc l'avantage d'améliorer grandement la quantité de jus récupéré dans l'espace suite au mixage des aliments. Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Ainsi, dans une variante de réalisation non illustrée, le filtre pourra comporter des moyens de guidage permettant seulement un déplacement axial du poussoir le long du filtre plutôt qu'un déplacement hélicoïdal. A culinary preparation apparatus equipped with such a pusher therefore has the advantage of greatly improving the amount of juice recovered in space following the mixing of food. Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention. Thus, in an embodiment variant not illustrated, the filter may comprise guide means allowing only an axial displacement of the push along the filter rather than a helical movement.
Ainsi, dans une variante d'utilisation de l'appareil précédemment décrit, le poussoir pourra être descendu progressivement le long du filtre par l'utilisateur lorsque le moteur de l'appareil est en fonctionnement, cette manœuvre pouvant s'effectuer sans risque étant donné que le poussoir ne peut pas rentrer en contact avec l'outil rotatif. Thus, in a variant of use of the device described above, the pusher may be lowered gradually along the filter by the user when the engine of the device is in operation, this maneuver can be carried out without risk given that the pusher can not come into contact with the rotary tool.
