APPAREIL ELECTROMENAGER DE PREPARATION CULINAIRE, DU GENRE ROBOT MENAGER, COMPORTANT UN DISPOSITIF HOUSEHOLD HOUSEHOLD APPLIANCE FOR FOOD PREPARATION, COMPRISING A DEVICE
D'ETANCHEITESEALING
DOMAINE TECHNIQUETECHNICAL AREA
La présente invention concerne un appareil électroménager de préparation culinaire, du genre robot ménager, comportant un corps comprenant un bloc moteur, un récipient de travail prévu pour recevoir un organe rotatif de travail entraîné par le bloc moteur, ainsi qu'un couvercle susceptible d'être disposé sur le récipient de travail selon un mouvement simple pour procéder au verrouillage de l'appareil.The present invention relates to an appliance for preparing food, of the household robot type, comprising a body comprising an engine block, a working container designed to receive a rotary working member driven by the engine block, as well as a cover capable of be placed on the working container in a simple movement to lock the device.
Par appareil électroménager de préparation culinaire, du genre robot ménager, on entend un appareil prévu pour réaliser des préparations hachées, des mélanges, ou encore des préparations râpées ou émincées.By household appliance for culinary preparation, of the household robot type, is meant an appliance intended for making chopped preparations, mixtures, or even grated or minced preparations.
TECHNIQUE ANTERIEUREPRIOR ART
Le document EP 0 549 818 décrit un appareil électroménager de préparation culinaire comprenant un récipient de travail susceptible d'être monté bloqué en rotation sur un corps au moyen d'un système de baïonnette, et un couvercle susceptible d'être verrouillé sur le récipient de travail au moyen d'un système de baïonnette. Une telle réalisation permet le maintien du récipient de travail sur le corps lors du fonctionnement de l'appareil, mais ne garantit pas une bonne étanchéité du couvercle sur le récipient de travail. Un système à baïonnette demande un joint pour assurer une bonne étanchéité. L'introduction d'un tel joint dans une réalisation comportant un récipient de travail et un couvercle réalisés en matière plastique est en effet difficilement compatible avec les caractéristiques mécaniques des matières utilisées.The document EP 0 549 818 describes a household appliance for culinary preparation comprising a working container capable of being mounted locked in rotation on a body by means of a bayonet system, and a cover capable of being locked on the cooking container. work by means of a bayonet system. Such an embodiment allows the working container to be held on the body during the operation of the device, but does not guarantee a good seal of the cover on the working container. A bayonet system requires a seal to ensure a good seal. The introduction of such a seal in an embodiment comprising a working container and a cover made of plastic material is indeed hardly compatible with the characteristics mechanics of the materials used.
Le document FR 2 370 456 décrit un mélangeur électroménager comprenant un récipient de travail dont le bord supérieur est de géométrie de révolution, ledit récipient étant disposé sur un socle et fermé par un couvercle, le verrouillage du couvercle étant assuré par un levier d'actionnement pivotant autour d'un axe horizontal et s'appliquant par un palier mobile contre un levier de verrouillage, lequel pivote autour d'un palier fixe et prend appui contre le couvercle. Le palier fixe peut se mouvoir librement d'une distance déterminée dans le sens axial. Partant dudit palier fixe une tige de commande guide un interrupteur jusqu'à un bouton d'actionnement du circuit commandant le moteur de l'appareil.Document FR 2 370 456 describes a household mixer comprising a working container, the upper edge of which is of geometry of revolution, said container being placed on a base and closed by a cover, the locking of the cover being ensured by an actuating lever. pivoting about a horizontal axis and applying by a movable bearing against a locking lever, which pivots around a fixed bearing and bears against the cover. The fixed bearing can move freely from a determined distance in the axial direction. Starting from said fixed bearing, a control rod guides a switch to a button for actuating the circuit controlling the motor of the device.
Une telle réalisation offre l'avantage de proposer un appareil dans lequel le couvercle peut être disposé sur le récipient de travail sans orientation précise, le récipient de travail pouvant être également disposé sans orientation précise sur le socle. Cette réalisation présente toutefois l'inconvénient d'utiliser un levier pivotant prenant appui sur le dessus du couvercle pour verrouiller le couvercle sur le corps. Dans le cas où cet appui exerce un effort de serrage insuffisant, le blocage en rotation du couvercle sur le récipient n'est pas assuré. Une telle construction est difficilement envisageable pour réaliser un appareil de préparation culinaire dans lequel seront réalisées des préparations râpées ou émincées dont les ingrédients sont introduits par une cheminée ménagée dans le couvercle, ou encore des préparations dans lesquelles l'outil travaille une pâte consistante. Dans le cas ou le bras présente un léger jeu avec le couvercle, l'étanchéité entre le récipient et le couvercle n'est pas assurée, ce qui peut être gênant en particulier lors de la réalisation de préparations liquides.Such an embodiment offers the advantage of providing an apparatus in which the cover can be placed on the working container without precise orientation, the working container can also be placed without precise orientation on the base. However, this embodiment has the drawback of using a pivoting lever resting on the top of the cover to lock the cover on the body. In the event that this support exerts an insufficient clamping force, the rotation of the cover on the container is not guaranteed. Such a construction is hardly conceivable for producing a culinary preparation appliance in which grated or minced preparations will be made, the ingredients of which are introduced through a chimney formed in the lid, or else preparations in which the tool works with a consistent paste. In the case where the arm has a slight clearance with the cover, the seal between the container and the cover is not ensured, which can be troublesome in particular when making liquid preparations.

Selon l'invention l'appareil comporte des moyens de blocage en rotation 225 du couvercle 5 par rapport au récipient 3, lesdits moyens s'enclenchant dans le sens vertical et étant combinés à un joint d'étanchéité 201 ; 202 ; 208 ; 212 engagé dans le sens vertical et à des moyens de maintien 6 de la position verticale fermée du couvercle 5.According to the invention the device comprises means for locking in rotation 225 of the cover 5 relative to the container 3, said means engaging in the vertical direction and being combined with a seal 201; 202; 208; 212 engaged in the vertical direction and to means 6 for maintaining the closed vertical position of the cover 5.
Selon le mode de réalisation présenté à la figure 1 , les moyens de maintien 6 de la position verticale fermée du couvercle 5 sont des mâchoires montées mobiles dans le sens radial. Tel que représenté à la figure 1 , les mâchoires formant les moyens de maintien 6 sont montées dans le corps 1 de l'appareil, chacune de ces mâchoires étant déplaçable contre un moyen de rappel 7 et susceptible de verrouiller le couvercle 5 par rapport au corps 1 , lorsque le couvercle 5 est disposé sur le récipient de travail 3 placé sur le socle 2. Les moyens de maintien 6 de la position verticale fermée du couvercle 5 forment un système de verrouillage dans lequel le couvercle 5 peut être disposé dans plusieurs positions sur le récipient 3, voire dans toute position angulaire. D'autres systèmes de verrouillage peuvent être envisagés, par exemple des mâchoires montées sur le couvercle 5, ou plus de deux mâchoires.According to the embodiment shown in Figure 1, the means 6 for maintaining the closed vertical position of the cover 5 are jaws mounted movable in the radial direction. As shown in FIG. 1, the jaws forming the holding means 6 are mounted in the body 1 of the device, each of these jaws being displaceable against a return means 7 and capable of locking the cover 5 relative to the body 1, when the cover 5 is disposed on the working container 3 placed on the base 2. The means 6 for holding the closed vertical position of the cover 5 form a locking system in which the cover 5 can be arranged in several positions on the container 3, or even in any angular position. Other locking systems can be envisaged, for example jaws mounted on the cover 5, or more than two jaws.
Tel que représenté aux figures 1 et 2, les moyens de blocage en rotation 225 du couvercle 5 par rapport au récipient 3 sont constitués par deux séries de rampes 220 ; 221 ménagées respectivement sur le couvercle 5 et le récipient 3.As shown in Figures 1 and 2, the rotation locking means 225 of the cover 5 relative to the container 3 are constituted by two series of ramps 220; 221 formed respectively on the cover 5 and the container 3.
Tel que montré aux figures 4 à 7, les rampes 220 sont disposées avantageusement au niveau d'un décrochement annulaire intérieur 190 de la jupe 15 du couvercle 5, et les rampes 221 sont avantageusement ménagées sur un décrochement annulaire extérieur 195 de la paroi 28 du récipient 3. La présence de rampes 220 ; 221 de géométrie périodique permet de faciliter la mise en place du couvercle 5 depuis n'importe quelle position angulaire initiale.As shown in Figures 4 to 7, the ramps 220 are advantageously arranged at an internal annular recess 190 of the skirt 15 of the cover 5, and the ramps 221 are advantageously provided on an external annular recess 195 of the wall 28 of the container 3. The presence of ramps 220; 221 of periodic geometry makes it easier to place the cover 5 from any initial angular position.
Tel que montré mieux montré à la figure 2 les rampes 220 ménagées sur le couvercle 5 sont symétriques et forment des nervures annulaires ondulées 191. Les rampes 221 ménagées sur le récipient 3 sont également symétriques et forment des nervures annulaires 194. A titre de variante les nervures annulaires peuvent être prévues sur le couvercle 5 alors que les nervures annulaires ondulées sont prévues sur le récipient 3.As shown better shown in Figure 2 the ramps 220 formed on the cover 5 are symmetrical and form corrugated annular ribs 191. The ramps 221 formed on the container 3 are also symmetrical and form annular ribs 194. As a variant the annular ribs can be provided on the cover 5 while the corrugated annular ribs are provided on the container 3.
Les nervures ondulées 191 sont de préférence périodiques, et par exemple sinusoïdales avec douze bosses 192 et douze creux 193. Les nervures annulaires 194 sont au minimum au nombre de deux et de préférence au nombre de trois ou quatre. De façon préférentielle la courbure des nervures 191 suit la courbure des nervures 194, de manière à favoriser la rotation du couvercle 5 lorsque celui-ci est disposé sur le récipient 3, afin que le couvercle 5 occupe une position stable par rapport au récipient 3. Cette disposition favorise le blocage en rotation du couvercle 5 par rapport au récipient 3.The corrugated ribs 191 are preferably periodic, and for example sinusoidal with twelve bumps 192 and twelve recesses 193. The annular ribs 194 are at least two in number and preferably three or four in number. Preferably, the curvature of the ribs 191 follows the curvature of the ribs 194, so as to favor the rotation of the cover 5 when the latter is placed on the container 3, so that the cover 5 occupies a stable position relative to the container 3. This provision promotes locking in rotation of the cover 5 relative to the container 3.
Tel que montré à la figure 1 le couvercle 5 comporte avantageusement une gorge annulaire 198 prévue pour recevoir un bord périphérique supérieur 197 de la paroi 28 du récipient 3. La gorge 198 est suffisamment profonde pour absorber d'éventuels jeux verticaux entre le couvercle 5 et le récipient 3.As shown in FIG. 1, the cover 5 advantageously comprises an annular groove 198 designed to receive an upper peripheral edge 197 of the wall 28 of the container 3. The groove 198 is deep enough to absorb any vertical play between the cover 5 and container 3.
Selon un premier exemple de réalisation présenté à la figure 4 le joint 201 est disposé au fond de la gorge 198. La taille du joint 201 est prévue de sorte que ledit joint soit déformé par le bord 197 du récipient 3 lorsque le couvercle 5 est verrouillé sur ledit récipient. Selon un deuxième exemple de réalisation présenté à la figure 5 le joint 202 comporte la gorge 198. Une nervure annulaire 203 ménagée sur une paroi latérale de la gorge 198 est prévue pour coopérer avec une paroi 199 du récipient 3 lorsque le couvercle 5 est verrouillé sur ledit récipient.According to a first embodiment shown in Figure 4 the seal 201 is disposed at the bottom of the groove 198. The size of the seal 201 is provided so that said seal is deformed by the edge 197 of the container 3 when the cover 5 is locked on said container. According to a second exemplary embodiment presented in FIG. 5, the seal 202 includes the groove 198. An annular rib 203 formed on a side wall of the groove 198 is provided to cooperate with a wall 199 of the container 3 when the cover 5 is locked on said container.
Selon un troisième exemple de réalisation présenté à la figure 6 le joint 208 comporte une couronne annulaire 209 susceptible d'être déformée en flexion par le bord supérieur 197 ou la paroi 199 du récipient 3 lorsque le couvercle 5 est verrouillé sur ledit récipient.According to a third embodiment presented in FIG. 6, the seal 208 comprises an annular ring 209 capable of being deformed in bending by the upper edge 197 or the wall 199 of the container 3 when the cover 5 is locked on said container.
Selon un quatrième exemple de réalisation présenté à la figure 7 le joint 212 comporte un bord annulaire chanfreiné 214 prévu pour coopérer avec un bord chanfreiné 215 du récipient 3 lorsque le couvercle 5 est verrouillé sur ledit récipient.According to a fourth embodiment shown in Figure 7 the seal 212 has a chamfered annular edge 214 provided to cooperate with a chamfered edge 215 of the container 3 when the cover 5 is locked on said container.
Le joint 202, 208, 212 représenté aux figures 5 à 7 est avantageusement surmoulé. A titre de variante, le joint peut être rapporté, ou fixé par tout moyen approprié. De préférence le joint 201 ; 202 ; 208 ; 212 est déformé par le récipient 3 lorsque le couvercle 5 est maintenu en position verticale fermée sur le récipient 3 même lorsque les rampes 220 ménagées sur le couvercle 5 coopèrent avec les rampes 221 ménagées sur le récipient 3 pour soulever le couvercle 5 par rapport au récipient 3, de manière à assurer un bonne étanchéité aussi lors de la réalisation de préparations râpées ou émincées. A titre de variante, non représentée aux figures, le joint 201 ; 202 ; 208 ; 212 peut être prévu sur le récipient de travail 3, pour coopérer avec une paroi ou un bord périphérique inférieur du couvercle 5.The seal 202, 208, 212 shown in Figures 5 to 7 is advantageously molded. Alternatively, the seal can be attached, or fixed by any suitable means. Preferably the seal 201; 202; 208; 212 is deformed by the container 3 when the cover 5 is kept in the closed vertical position on the container 3 even when the ramps 220 formed on the cover 5 cooperate with the ramps 221 formed on the container 3 to lift the cover 5 relative to the container 3, so as to ensure a good seal also when making grated or minced preparations. As a variant, not shown in the figures, the seal 201; 202; 208; 212 may be provided on the working container 3, to cooperate with a wall or a lower peripheral edge of the cover 5.
Avantageusement, tel que représenté à la figure 3, les moyens de blocage en rotation 224 du récipient 3 par rapport au socle 2 sont engagés dans le sens vertical et sont formés par des nervures annulaires ondulées 180 ménagées à l'extérieur du récipient 3 sous le fond 29, de préférence de manière périodique, par exemple sinusoïdale avec douze bosses 182 et douze creux 183, lesdites nervures annulaires 180 étant prévues pour coopérer avec des nervures radiales 181 ménagées sur le socle 2 du corps 1. De façon préférentielle la courbure des nervures annulaires 180 suit la courbure des nervures radiales 181 , tel que représenté à la figure 3, de manière à favoriser la rotation du récipient 3 afin d'occuper une position stable lorsque celui-ci est disposé sur le socle 2. D'autres moyens de blocage du récipient de travail 3 sur le socle 2 sont envisageables, par exemple un système à baïonnette.Advantageously, as shown in FIG. 3, the means for locking in rotation 224 of the container 3 relative to the base 2 are engaged in the vertical direction and are formed by corrugated annular ribs 180 formed outside the container 3 under the bottom 29, preferably periodically, for example sinusoidal with twelve bumps 182 and twelve recesses 183, said annular ribs 180 being provided to cooperate with radial ribs 181 formed on the base 2 of the body 1. Preferably the curvature of the ribs annular 180 follows the curvature of the radial ribs 181, as shown in FIG. 3, so as to favor the rotation of the container 3 in order to occupy a stable position when the latter is placed on the base 2. Other means of blocking of the working container 3 on the base 2 can be envisaged, for example a bayonet system.
Le fonctionnement de la présente invention est le suivant :The operation of the present invention is as follows:
L'utilisateur dispose le récipient 3 sur le socle 2. Avantageusement les nervures 180 du récipient 3 coopérant avec les nervures 181 du socle 2 amènent le récipient 3 dans une position stable sur le socle 2. L'utilisateur n'a ainsi pas besoin de positionner précisément le récipient 3 sur le socle 2.The user places the container 3 on the base 2. Advantageously, the ribs 180 of the container 3 cooperating with the ribs 181 of the base 2 bring the container 3 into a stable position on the base 2. The user thus does not need to precisely position the container 3 on the base 2.
L'utilisateur dispose ensuite le couvercle 5 sur le récipient 3. Les nervures 191 ménagées sur le couvercle 5 coopèrent avec les nervures 194 ménagées sur le récipient 3 et amènent le couvercle 5 dans une position stable sur le récipient 3. Alternativement, l'utilisateur peut d'abord disposer le couvercle 5 sur le récipient 3 puis le récipient 3 surmonté du couvercle 5 sur le socle 2.The user then places the cover 5 on the container 3. The ribs 191 formed on the cover 5 cooperate with the ribs 194 formed on the container 3 and bring the cover 5 into a stable position on the container 3. Alternatively, the user can first place the cover 5 on the container 3 then the container 3 surmounted by the cover 5 on the base 2.
L'utilisateur verrouille le couvercle 5 disposé sur le récipient 3 en utilisant les moyens de maintien 6 en position verticale fermée du couvercle 5.The user locks the cover 5 placed on the container 3 by using the means 6 for holding the cover 5 in the closed vertical position.
Lors de la réalisation d'une préparation les moyens de blocage 224 du récipient 3 sur le socle 2 bloquent la rotation du récipient 3 par rapport au corps 1. Le joint 201 ; 202 ; 208 ; 212 déformé lors de la mise en place du couvercle 5 sur le récipient 3 assure l'étanchéité entre le couvercle 5 et le récipient 3.When carrying out a preparation, the blocking means 224 of the container 3 on the base 2 block the rotation of the container 3 relative to the body 1. The seal 201; 202; 208; 212 deformed during the fitting of the cover 5 on the container 3 seals between the cover 5 and the container 3.
Les nervures 191 ménagées sur le couvercle 5 coopérant avec les nervures 194 ménagées sur le récipient 3 bloquent la rotation du couvercle 5 sur le récipient 3 qui pourrait survenir par exemple lors de la réalisation de préparations râpées ou émincées. Le début de rotation du couvercle 5 par rapport au récipient 3 provoque l'écartement des creux 193 du sommet des nervures 194. Cette rotation contribue à diminuer la déformation du joint 201 ; 202 ; 208 ; 212, tout en conservant avantageusement une étanchéité entre le couvercle 5 et le récipient 3, les moyens de maintien de la position verticale fermée 6 empêchant l'ouverture dudit couvercle.The ribs 191 formed on the cover 5 cooperating with the ribs 194 formed on the container 3 block the rotation of the cover 5 on the container 3 which could occur for example during the production of grated or minced preparations. The beginning of rotation of the cover 5 with respect to the container 3 causes the recesses 193 to be separated from the top of the ribs 194. This rotation contributes to reducing the deformation of the seal 201; 202; 208; 212, while advantageously retaining a seal between the cover 5 and the container 3, the means for maintaining the closed vertical position 6 preventing the opening of said cover.
L'invention n'est nullement limitée strictement aux exemples de réalisation décrits précédemment, mais englobe de nombreuses modifications ou améliorations. Notamment la cheminée centrale 20 peut être remplacée par une traversée étanche de paroi permettant la transmission du mouvement à l'outil, tel que connu sur les appareils électroménagers de type mélangeurs, prévus pour la réalisation de préparations liquides.The invention is in no way strictly limited to the embodiments described above, but encompasses numerous modifications or improvements. In particular, the central chimney 20 can be replaced by a sealed wall passage allowing the transmission of movement to the tool, as known on household appliances of the mixer type, provided for the production of liquid preparations.
