DESCRIPTION DESCRIPTION
TITRE : APPAREIL ELECTROMENAGER COMPRENANT UN ORGANE DE MELANGE TITLE: HOUSEHOLD APPLIANCE INCLUDING A MIXING DEVICE
Domaine de l’invention Field of the invention
La présente invention concerne le domaine des appareils électroménagers destinés à la préparation et/ou à la cuisson d’aliments. Elle vise en particulier, un appareil de petit électroménager de puériculture mais de manière non-exclusive. The present invention relates to the field of household appliances intended for the preparation and/or cooking of food. It aims in particular at a small childcare appliance but in a non-exclusive manner.
Arrière-plan technique Technical background
Il est connu différents types d’appareils électroménagers qui sont destinés à la préparation et/ou la cuisson des aliments, la cuisson pouvant être réalisée uniquement à la vapeur ou non. Des exemples d’appareils sont décrits dans les documents US-A1- 2012/073450, US-A-6076452, US-A1 -2008/213447 et CN-A-109381067. Different types of household appliances are known which are intended for the preparation and/or cooking of food, the cooking being able to be carried out only with steam or not. Examples of devices are described in documents US-A1-2012/073450, US-A-6076452, US-A1-2008/213447 and CN-A-109381067.
Les appareils comprennent également un bol qui peut être utilisé pour la préparation des aliments et/ou pour la cuisson des aliments. Un tel bol comprend classiquement des lames qui sont disposées au fond de celui-ci et qui sont configurées pour être entraînées en rotation de façon à hacher ou couper les aliments. The appliances also include a bowl that can be used for food preparation and/or cooking. Such a bowl conventionally comprises blades which are arranged at the bottom thereof and which are configured to be rotated so as to chop or cut the food.
Les appareils qui permettent une cuisson à la vapeur comprennent un panier de cuisson dans lequel sont installés les aliments à cuire et qui est destiné à être installé dans le bol de préparation de manière amovible. Le panier de cuisson comprend un fond ajouré permettant le passage de la vapeur. La vapeur est générée par un générateur de vapeur qui est séparé du bol de préparation. Des moyens sont prévus pour permettre la circulation de la vapeur vers le panier de cuisson se trouvant dans le bol de préparation. La vapeur circule à l’intérieur du panier puis vers le bol de préparation en traversant le fond ajouré du panier. The devices which allow steam cooking include a cooking basket in which the food to be cooked is installed and which is intended to be installed in the preparation bowl in a removable manner. The cooking basket includes a perforated bottom allowing steam to pass through. The steam is generated by a steam generator which is separate from the preparation bowl. Means are provided to allow the circulation of steam towards the cooking basket located in the preparation bowl. The steam circulates inside the basket then towards the preparation bowl through the perforated bottom of the basket.
Cependant, les aliments sont généralement coupés en cubes de tailles plus ou moins importantes et reposent sur le fond du panier de cuisson jusqu’à une certaine hauteur. La cuisson des aliments situés sur le fond du panier est différente de ceux situés en partie supérieure du panier. Les aliments situés à proximité du fond du panier peuvent être plus cuits que ceux se trouvant vers l’ouverture supérieure du panier de cuisson car le flux de vapeur ne circule pas convenablement entre les différents morceaux qui sont enchevêtrés jusqu’au fond du panier. Des morceaux d’aliments non cuits sont durs et peuvent conduire à des difficultés d’ingestion de ceux-ci voire à étouffement d’un enfant et/ou à l’ingestion de bactéries ou micro-organismes pathogènes contenus dans les aliments. Dans le cas où les aliments sont destinés à l’alimentation des enfants, augmenter le temps de cuisson nuirait à la qualité nutritionnelle des morceaux d’aliments qui se trouvent en partie supérieure car ceux-ci seraient trop cuits. However, the food is generally cut into cubes of varying sizes and rests on the bottom of the cooking basket up to a certain height. The cooking of foods located at the bottom of the basket is different from those located at the top of the basket. Foods located near the bottom of the basket may be more cooked than those located towards the upper opening of the cooking basket because the flow of steam does not circulate properly between the different pieces which are entangled to the bottom of the basket. Pieces of uncooked food are hard and can lead to difficulty ingesting them or even to choking of a child and/or to the ingestion of pathogenic bacteria or micro-organisms contained in the food. In the case where the food is intended for feeding children, increasing the cooking time would harm the nutritional quality of the pieces of food which are in the upper part because they would be overcooked.
Le but de la présente invention est de fournir un appareil électroménager remédiant aux inconvénients précités. L’appareil électroménager a pour but de réaliser une cuisson homogène tout en étant simple et économique en termes de coût de fabrication et de coût d’énergie. The aim of the present invention is to provide a household appliance which overcomes the aforementioned drawbacks. The aim of the household appliance is to achieve uniform cooking while being simple and economical in terms of manufacturing cost and energy cost.

Description détaillée de l’invention Detailed description of the invention
La figure 1 illustre un exemple d’appareil électroménager 1 pour la préparation et/ou la cuisson d’aliments. Cet appareil électroménager est destiné à la cuisson d’aliments notamment à la vapeur pour les enfants mais pas exclusivement, et le mixage des aliments une fois cuits. Figure 1 illustrates an example of a household appliance 1 for preparing and/or cooking food. This household appliance is intended for cooking food, particularly by steaming it for children but not exclusively, and for mixing food once cooked.
Cet appareil électroménager 1 comprend un boîtier 2 pourvu d’un socle 3 et d’un bol 4 de préparation et/ou de cuisson destiné à être disposé de manière amovible sur le socle 3 du boîtier 2. This household appliance 1 comprises a housing 2 provided with a base 3 and a bowl 4 for preparation and/or cooking intended to be arranged removably on the base 3 of the housing 2.
En référence à la figure 2, le bol 4 de préparation et/ou de cuisson comprend avantageusement un fond 5 et une paroi latérale 6 s’élevant depuis le fond 5. La paroi latérale 6 et le fond 5 déterminent un volume interne de cuisson et/ou de préparation. La paroi latérale 6 présente une forme générale cylindrique d’axe longitudinal X. Le bol 4 comprend une ouverture 7 par laquelle les aliments sont introduits dans le bol 4 et en particulier dans le volume interne. L’ouverture 7, opposée au fond 5 du bol 4, est délimitée par une bordure périphérique 8 de la paroi latérale 6. De manière avantageuse, mais non limitativement, le bol 4 est équipé d’une poignée 9 qui permet de faciliter la manipulation du bol 4. La poignée 9 est montée sur la paroi latérale 6. La poignée 9 présente une forme globale allongée suivant un axe parallèle à l’axe longitudinal X. L’appareil électroménager 1 comprend de manière avantageuse un couvercle 10 qui permet de fermer le bol 4 de préparation et/ou de cuisson. With reference to Figure 2, the preparation and/or cooking bowl 4 advantageously comprises a bottom 5 and a side wall 6 rising from the bottom 5. The side wall 6 and the bottom 5 determine an internal cooking volume and /or preparation. The side wall 6 has a generally cylindrical shape with a longitudinal axis X. The bowl 4 comprises an opening 7 through which the food is introduced into the bowl 4 and in particular into the internal volume. The opening 7, opposite the bottom 5 of the bowl 4, is delimited by a peripheral edge 8 of the side wall 6. Advantageously, but not restrictively, the bowl 4 is equipped with a handle 9 which facilitates handling of the bowl 4. The handle 9 is mounted on the side wall 6. The handle 9 has an overall shape elongated along an axis parallel to the longitudinal axis X. The household appliance 1 advantageously comprises a cover 10 which allows the preparation and/or cooking bowl 4 to be closed.
Sur les figures 3 et 4, l’appareil 1 comprend un outil de travail 11 qui est agencé dans le fond 5 du bol 4 de préparation et/ou de cuisson. De préférence, mais non limitativement, l’outil de travail 11 est monté de manière amovible dans le fond 5 du bol 4. Cela permet de faciliter le nettoyage du bol 4 et/ou de l’outil de travail 11 ainsi que le remplacement de ce dernier en cas de détérioration. L’outil de travail 11 est destiné à être entraîné en rotation par un arbre d’entraînement 12 (représenté sur la figure 6 décrite ci-après) suivant un axe de rotation A. L’axe de rotation A est parallèle à l’axe longitudinal X. Avantageusement, l’arbre d’entraînement 12 traverse le fond 5 du bol suivant l’axe de rotation A. L’arbre d’entraînement 12 est mis en rotation par un moteur électrique 13. Ce dernier est installé dans le boîtier 2. In Figures 3 and 4, the device 1 comprises a working tool 11 which is arranged in the bottom 5 of the preparation and/or cooking bowl 4. Preferably, but not limited to, the working tool 11 is removably mounted in the bottom 5 of the bowl 4. This makes it easier to clean the bowl 4 and/or the working tool 11 as well as the replacement of the latter in the event of deterioration. The working tool 11 is intended to be rotated by a drive shaft 12 (shown in Figure 6 described below) along an axis of rotation A. The axis of rotation A is parallel to the axis longitudinal X. Advantageously, the drive shaft 12 passes through the bottom 5 of the bowl along the axis of rotation A. The drive shaft 12 is rotated by an electric motor 13. The latter is installed in the housing 2.
L’outil de travail 11 comprend des lames de coupe 14 qui s’étendent transversalement par rapport à l’axe de rotation. Avantageusement, les lames de coupe 14 sont au nombre de deux et sont opposées l’une à l’autre (sensiblement dans un plan perpendiculaire à l’axe de rotation). Chaque lame de coupe 14 présente un bord tranchant 15 permettant de hacher ou couper les aliments qui se trouvent au fond du bol. Nous entendons dans la présente invention par l’expression « bord tranchant » un bord qui est formé par une surface biseautée. Lors du hachage, les aliments peuvent être divisés en des morceaux très fins jusqu’à obtenir une purée. The working tool 11 comprises cutting blades 14 which extend transversely with respect to the axis of rotation. Advantageously, the cutting blades 14 are two in number and are opposed to each other (substantially in a plane perpendicular to the axis of rotation). Each cutting blade 14 has a cutting edge 15 allowing food to be chopped or cut at the bottom of the bowl. In the present invention, we understand by the expression “cutting edge” an edge which is formed by a beveled surface. When chopping, food can be broken into very fine pieces until you obtain a puree.
Suivant un exemple de réalisation représenté sur la figure 4, l’outil de travail 11 comprend un support 16 qui est pourvu d’une embase 17 et d’un arbre de support 18 s’étendant depuis l’embase 17. L’embase 17 présente une forme sensiblement circulaire et présente une surface externe définie sensiblement dans plan B. L’arbre de support 18 s’étend suivant un axe C perpendiculaire au plan de l’embase 17. Avantageusement, l’outil de travail 11 comprend un organe de préhension 19 qui permet la manipulation de l’outil de travail lors de son montage ou de son retrait dans le bol 4. L’organe de préhension 19 est porté par le support 16. L’organe de préhension 19 s’étend en saillie depuis l’embase 17 et de manière opposée à l’arbre de support 18 suivant l’axe C.

En référence à la figure 6, la vapeur permettant de cuire les aliments est produite grâce à des moyens 40 de génération de vapeur. Les moyens 40 de génération de vapeur comprennent une cuve 41 qui est installée dans le boîtier 2. La cuve 41 est séparée du bol 4 par une paroi 42. La cuve 41 est destinée à être alimentée par une quantité d’eau. Les moyens 40 de génération de vapeur comprennent un dispositif de chauffage 43 qui permet de réchauffer la quantité d’eau située dans la cuve 41 pour la transformer en vapeur. Dans le présent exemple, le dispositif de chauffage comprend une résistance électrique qui est disposée sous le fond de la cuve 41 . Alternativement, la résistance électrique constitue le fond de la cuve 41. La résistance électrique est reliée à une source d’alimentation électrique (non représentée). D’autres éléments de chauffage permettant de chauffer l’eau et la transformer en vapeur peuvent être installés dans le boîtier 2. With reference to Figure 6, the steam allowing food to be cooked is produced using means 40 for generating steam. The means 40 for generating steam comprise a tank 41 which is installed in the housing 2. The tank 41 is separated from the bowl 4 by a wall 42. The tank 41 is intended to be supplied with a quantity of water. The means 40 for generating steam include a heating device 43 which makes it possible to heat the quantity of water located in the tank 41 to transform it into steam. In the present example, the heating device comprises an electrical resistance which is placed under the bottom of the tank 41. Alternatively, the electrical resistance constitutes the bottom of the tank 41. The electrical resistance is connected to an electrical power source (not shown). Other heating elements allowing the water to be heated and transformed into steam can be installed in box 2.
Sur la figure 6, les moyens 40 de génération de vapeur (générateur de vapeur) sont reliés au panier de cuisson 24 via des moyens 45 de communication fluidique. Dans le présent exemple, les moyens 45 de communication fluidique comprennent une canalisation 46 qui débouche dans la cuve 41. La canalisation 46 traverse également la paroi de séparation 42 du boîtier 2 qui s’élève depuis le socle 3 du boîtier 2. La canalisation 46 est dotée d’une entrée 46a qui débouche sur une surface interne de la cuve 41. La canalisation 46 est dotée également d’une sortie 46b qui débouche avantageusement sur une surface externe de la paroi de séparation 42. In Figure 6, the steam generation means 40 (steam generator) are connected to the cooking basket 24 via fluid communication means 45. In the present example, the fluid communication means 45 comprise a pipe 46 which opens into the tank 41. The pipe 46 also passes through the separation wall 42 of the housing 2 which rises from the base 3 of the housing 2. The pipe 46 is provided with an inlet 46a which opens onto an internal surface of the tank 41. The pipe 46 is also provided with an outlet 46b which advantageously opens onto an external surface of the separation wall 42.
De manière avantageuse, le couvercle 10 comprend également un orifice 47 traversant sa paroi de part et d’autre et qui est destiné à communiquer fluidiquement avec la canalisation 46. Le couvercle 10 comprend un verrou qui permet de verrouiller le couvercle sur le bol 4 et notamment dans une position dans laquelle l’orifice d’entrée 47 est en regard de la canalisation 46. Préférentiellement, un joint d’étanchéité 48 est agencé au niveau de la sortie 46b de la canalisation 46 et est destiné à être en appui contre une portion de surface externe 49 du couvercle 10. Le joint d’étanchéité 48 entoure l’orifice d’entrée 47 du couvercle 10. Cela permet d’éviter les fuites de vapeur entre la canalisation 46 et l’orifice d’entrée 47. De la sorte, la canalisation 46 et l’orifice d’entrée 47 permettent de faire circuler la vapeur depuis la cuve 41 vers le panier 24 installé dans le bol 4. La vapeur circule également dans le panier de cuisson 24, vers le fond ajouré 25 du panier de cuisson 24, puis en-dessous du panier 24 et enfin le long de l’espace entre les parois latérales 6, 26 du panier de cuisson 24 et du bol 4. De manière avantageuse, mais non limitativement, le couvercle 10 comprend un orifice de sortie (non représenté) permettant l’évacuation de la vapeur. Advantageously, the cover 10 also includes an orifice 47 passing through its wall on either side and which is intended to communicate fluidly with the pipe 46. The cover 10 includes a lock which makes it possible to lock the cover on the bowl 4 and in particular in a position in which the inlet orifice 47 faces the pipe 46. Preferably, a seal 48 is arranged at the outlet 46b of the pipe 46 and is intended to bear against a external surface portion 49 of the cover 10. The seal 48 surrounds the inlet orifice 47 of the cover 10. This makes it possible to avoid steam leaks between the pipe 46 and the inlet orifice 47. In this way, the pipe 46 and the inlet orifice 47 make it possible to circulate the steam from the tank 41 towards the basket 24 installed in the bowl 4. The steam also circulates in the cooking basket 24, towards the perforated bottom 25 of the cooking basket 24, then below the basket 24 and finally along the space between the side walls 6, 26 of the cooking basket 24 and the bowl 4. Advantageously, but not limited to, the cover 10 comprises an outlet orifice (not shown) allowing steam to be evacuated.
Avantageusement, le couvercle 10 comprend une double paroi 10a, 10b pour favoriser l’isolation thermique de la zone de cuisson.

L’organe de mélange 50 comprend également au moins une pale 52 s’étendant transversalement depuis la tige 51. La pale permet de mieux brasser et répartir les aliments dans le panier au cours de la cuisson. Dans le présent exemple, la tige 51 présente une section suivant l’axe d’allongement E qui est sensiblement conique ou tronconique. The mixing member 50 also comprises at least one blade 52 extending transversely from the rod 51. The blade makes it possible to better mix and distribute the food in the basket during cooking. In the present example, the rod 51 has a section along the elongation axis E which is substantially conical or frustoconical.
De manière avantageuse, la pale 52 est une unique pale. La pale 51 présente une épaisseur e constante mesurée entre une surface externe 53 et une surface interne 54. La pale 52 comprend un bord latéral 55 plat. La pale 52 est dépourvue de bord tranchant. Advantageously, the blade 52 is a single blade. The blade 51 has a constant thickness e measured between an external surface 53 and an internal surface 54. The blade 52 includes a flat side edge 55. The blade 52 has no sharp edge.
Avantageusement, la pale 52 est agencée de manière hélicoïdale autour de la tige 51 suivant l’axe d’allongement E comme cela est visible sur les figures 3 et 7. La pale 52 comprend également une pluralité d’orifices 56 traversant sa paroi de part et d’autre (dans le sens de l’épaisseur e). Chaque orifice 56 débouche sur la surface externe 53 et sur la surface interne 54. De la sorte, la circulation de la vapeur à travers les aliments M est davantage facilitée. Advantageously, the blade 52 is arranged helically around the rod 51 along the axis of elongation E as is visible in Figures 3 and 7. The blade 52 also comprises a plurality of orifices 56 passing through its side wall and on the other (in the direction of thickness e). Each orifice 56 opens onto the external surface 53 and onto the internal surface 54. In this way, the circulation of steam through the food M is further facilitated.
De manière avantageuse, l’organe de mélange 50 est réalisé dans un matériau polymère. Un exemple de matériau polymère est un polyoxyméthylène ou un polycaprolactame. L’organe de mélange peut être encore réalisé dans un autre matériau polymère ayant de bonnes résistances thermomécaniques. Advantageously, the mixing member 50 is made of a polymer material. An example of a polymer material is a polyoxymethylene or a polycaprolactam. The mixing member can also be made of another polymer material having good thermomechanical resistance.
Au moins une portion de la tige 51 traverse l’orifice central 44 du panier de cuisson de sorte à permettre la liaison de l’organe de mélange 50 avec l’arbre d’entraînement 12. At least a portion of the rod 51 passes through the central orifice 44 of the cooking basket so as to allow the connection of the mixing member 50 with the drive shaft 12.
Pour cela, en référence aux figures 3, 8, 9 et 10, l’appareil électroménager comprend un organe d’accouplement 60 configuré de manière à relier l’organe de mélange 50 à l’outil de travail 11. En particulier, l’organe d’accouplement 60 comprend une forme générale cylindrique d’axe de révolution F.

As shown in Figures 3 and 8, the rotation guide member comprises a plain bearing 72 which is mounted in the central orifice 44 of the cooking basket 24. More precisely, the cooking basket 24 comprises a tubular wall 44a which delimits the central orifice 44 centered on the axis D of the basket 24. The smooth bearing 72 has a hollow cylindrical body 72a mounted tight and strong on the tubular wall 44a. Other means of mounting the plain bearing in the basket 24 are of course possible. Likewise, the rotation guide member 71 may include other elements facilitating rotation and supporting humidity as well as heat. The plain bearing 72 also includes a flange 72b arranged at one end of the cylindrical body 72a. The collar 72b is intended to rest on a peripheral free edge (oriented in the basket) of the tubular wall 44a. In the installation situation, the cylindrical wall 62 of the coupling member 60 is inserted inside the cylindrical body 72a of the plain bearing. The base 61 of the coupling member 60 faces an external surface portion 25a (visible in Figure 5) of the perforated bottom 25.
De manière avantageuse, une rondelle 73 est agencée entre la portion de surface externe 25a du fond ajouré 25 et une surface annulaire externe 61a de la base 61 de l’organe d’accouplement 60. La rondelle 73 permet de protéger l’organe d’accouplement de l’usure et d’éviter les échauffements. Afin de retenir la rondelle 73, une nervure 74 est agencée sur le fond ajouré 25 du panier de cuisson 24. Avantageusement, la nervure 74 est annulaire, centrée sur l’axe D et s’étend vers l’extérieur du fond ajouré 25 suivant l’axe D. La nervure 74 présente de manière avantageuse, une excroissance s’étendant radialement vers l’axe D et permettant de maintenir la rondelle 73 en position. Plus précisément encore, la rondelle 73 est fixe par rapport au panier. L’organe d’accouplement est entraîné en rotation par rapport à la rondelle et la surface annulaire externe 61a de l’organe d’accouplement vient en contact avec la rondelle 73. Advantageously, a washer 73 is arranged between the outer surface portion 25a of the perforated bottom 25 and an outer annular surface 61a of the base 61 of the coupling member 60. The washer 73 makes it possible to protect the coupling member coupling from wear and to avoid overheating. In order to retain the washer 73, a rib 74 is arranged on the perforated bottom 25 of the cooking basket 24. Advantageously, the rib 74 is annular, centered on the axis D and extends towards the outside of the next perforated bottom 25 the axis D. The rib 74 advantageously presents a protrusion extending radially towards the axis D and making it possible to hold the washer 73 in position. Even more precisely, the washer 73 is fixed relative to the basket. The coupling member is rotated relative to the washer and the external annular surface 61a of the coupling member comes into contact with the washer 73.
La rondelle 73 et l’organe de guidage sont avantageusement, mais non limitativement, réalisés dans un matériau métallique et de préférence en inox. L’inox permet d’augmenter la durée de vie de l’appareil en réduisant notamment l’usure entre l’organe d’accouplement et la rondelle 73. The washer 73 and the guide member are advantageously, but not limited to, made of a metallic material and preferably of stainless steel. Stainless steel increases the lifespan of the device by notably reducing wear between the coupling member and washer 73.
Suivant une alternative représentée sur la figure 11 , le palier lisse présente une forme d’un seul tenant en L avec une première partie formant le corps cylindrique 72a et une deuxième partie formant la rondelle 72c. La rondelle 72c est centrée sur l’axe de révolution du palier lisse et est située à une extrémité du corps cylindrique 72a. Le palier lisse en L est monté également serré et en force dans le panier de sorte que celui-ci soit fixe dans le panier et que l’organe d’accouplement soit entraîné en rotation par rapport au palier lisse. En particulier, la rondelle 72c est agencée entre la portion de surface externe 25a du fond ajouré 25 et la surface annulaire externe 61a de la base 61 de l’organe d’accouplement 60. Dans cet exemple de réalisation, la rondelle 72c présente avantageusement un rayon supérieur à celui de la base 61 de l’organe d’accouplement 60. According to an alternative shown in Figure 11, the plain bearing has a one-piece L-shaped shape with a first part forming the cylindrical body 72a and a second part forming the washer 72c. The washer 72c is centered on the axis of revolution of the plain bearing and is located at one end of the cylindrical body 72a. The L-shaped plain bearing is mounted equally tight and strong in the basket so that the latter is fixed in the basket and the coupling member is rotated relative to the plain bearing. In particular, the washer 72c is arranged between the outer surface portion 25a of the perforated bottom 25 and the outer annular surface 61a of the base 61 of the coupling member 60. In this exemplary embodiment, the washer 72c advantageously has a radius greater than that of the base 61 of the coupling member 60.
Suivant un exemple de réalisation et en référence à la figure 6, l’appareil électroménager comprend une unité électronique de commande 80 agencée pour contrôler l’alimentation électrique du moteur 13. L’unité électronique de commande 80 est configurée pour piloter le dispositif de chauffage 43 des moyens 40 de génération de vapeur. Avantageusement, l’unité électronique de commande 80 est installée dans le boîtier 2. L’unité électronique de commande 80 comprend plusieurs programmes de fonctionnement pour piloter les moyens de génération de vapeur 40 et/ou l’alimentation du moteur 13 qui entraîne l’arbre d’entraiment 12 en rotation. Les programmes sont mémorisés dans des mémoires dédiées que comprend l’unité 80. According to an exemplary embodiment and with reference to Figure 6, the household appliance comprises an electronic control unit 80 arranged to control the power supply electrical of the motor 13. The electronic control unit 80 is configured to control the heating device 43 of the steam generation means 40. Advantageously, the electronic control unit 80 is installed in the housing 2. The electronic control unit 80 comprises several operating programs for controlling the steam generation means 40 and/or the power supply of the motor 13 which drives the drive shaft 12 in rotation. The programs are stored in dedicated memories included in unit 80.
De manière avantageuse, l’appareil électroménager comprend un ou des boutons de commande (non représenté(s)) permettant de sélectionner un ou plusieurs programme(s) de fonctionnement. L’unité de commande 80 comprend par exemple un programme pour la cuisson à la vapeur des aliments et un programme pour le mixage des aliments cuits. Advantageously, the household appliance comprises one or more control buttons (not shown) making it possible to select one or more operating programs. The control unit 80 includes, for example, a program for steaming food and a program for mixing cooked food.
Dans chacun des programmes de fonctionnement, l’arbre d’entraînement 12 peut être entraîné en rotation. De manière avantageuse, pendant le programme de cuisson à la vapeur, l’organe de mélange 50 est entraîné en rotation par l’arbre d’entraînement 12. Suivant encore une autre caractéristique avantageuse, le moteur 13 qui entraine l’arbre d’entraînement 12 fonctionne par intermittence ou de manière séquencée pendant le programme de cuisson à la vapeur. En d’autres termes, l’organe de mélange 50 est entraîné en rotation de manière séquencée. Dans le cadre du programme de mixage des aliments, l’arbre d’entraînement 12 est entraîné en rotation de manière continue. In each of the operating programs, the drive shaft 12 can be rotated. Advantageously, during the steam cooking program, the mixing member 50 is rotated by the drive shaft 12. According to yet another advantageous characteristic, the motor 13 which drives the drive shaft 12 operates intermittently or in sequence during the steaming program. In other words, the mixing member 50 is rotated in a sequenced manner. As part of the food mixing program, the drive shaft 12 is rotated continuously.
De même, dans chacun des programmes, le dispositif de chauffage 13 peut être alimenté électriquement pour atteindre une ou plusieurs puissance(s) de chauffe prédéterminée de sorte à produire de la vapeur et/ou à cuire les aliments. Chaque puissance de chauffe peut être appliquée pendant une durée prédéterminée. Likewise, in each of the programs, the heating device 13 can be electrically powered to achieve one or more predetermined heating power(s) so as to produce steam and/or cook the food. Each heating power can be applied for a predetermined duration.
Nous allons désormais décrire les différentes étapes de montage de l’organe de mélange 50 dans l’appareil électroménager 1. Dans une première étape, le bol 24 est installé sur le socle 3 du boîtier 2 avec l’outil de travail 11 agencé préalablement sur son fond 5. L’arbre de support 18 est accouplé et solidaire en rotation à l’arbre d’entraînement 12 actionné par le moteur 13. We will now describe the different stages of mounting the mixing member 50 in the household appliance 1. In a first step, the bowl 24 is installed on the base 3 of the housing 2 with the working tool 11 previously arranged on its bottom 5. The support shaft 18 is coupled and secured in rotation to the drive shaft 12 actuated by the motor 13.
Dans une deuxième étape du procédé de montage, l’organe d’accouplement 60 est installé sur l’outil de travail 11 . L’organe de préhension 19 de l’outil de travail 11 est introduit dans le logement 64 de l’organe d’accouplement 60. De la sorte, l’organe d’accouplement 60 est rendu solidaire en rotation de l’outil de travail 11 . In a second step of the assembly process, the coupling member 60 is installed on the working tool 11. The gripping member 19 of the working tool 11 is introduced into the housing 64 of the coupling member 60. In this way, the coupling member 60 is made integral in rotation with the working tool 11.
Dans une troisième étape, le panier de cuisson 24 est inséré dans le bol 4 de préparation. Le panier de cuisson 24 est déjà équipé de l’organe de guidage en rotation (le palier lisse 72 ici) et de la rondelle 73, 72c (formée avec le palier lisse). La rondelle 73 distincte peut être surmoulée sur le panier 24. En installant le panier 24, la paroi cylindrique 62 de l’organe d’accouplement est insérée à l’intérieur du palier lisse 72. In a third step, the cooking basket 24 is inserted into the preparation bowl 4. The cooking basket 24 is already equipped with the rotation guide member (the plain bearing 72 here) and the washer 73, 72c (formed with the plain bearing). The separate washer 73 can be overmolded on the basket 24. By installing the basket 24, the cylindrical wall 62 of the coupling member is inserted inside the plain bearing 72.
Dans une quatrième étape, l’organe de mélange 50 est installé dans le panier de cuisson 24. Lors de son installation, la jupe cylindrique 59 de l’organe de mélange 50 traverse l’orifice central 44 du panier de cuisson 24 pour s’insérer dans la cavité centrale 65 de l’organe d’accouplement 60. Avantageusement, un rebord 70 libre de la jupe cylindrique 59 vient en contact avec le fond de la cavité centrale 65. L’organe de mélange 50 est alors solidaire en rotation de l’organe d’accouplement 60. L’organe de mélange 50 s’étend alors suivant l’axe de rotation A et dans le panier de cuisson 24. In a fourth step, the mixing member 50 is installed in the cooking basket 24. During its installation, the cylindrical skirt 59 of the mixing member 50 passes through the central orifice 44 of the cooking basket 24 to insert into the central cavity 65 of the coupling member 60. Advantageously, a free rim 70 of the cylindrical skirt 59 comes into contact with the bottom of the central cavity 65. The mixing member 50 is then integral in rotation of the coupling member 60. The mixing member 50 then extends along the axis of rotation A and into the cooking basket 24.
Les aliments M coupés en morceaux sont introduits dans le panier de cuisson 24. The food M cut into pieces is introduced into the cooking basket 24.
Le couvercle 10 est ensuite mis en place sur le bol 4 de préparation afin de fermer le volume interne et former la zone de cuisson. Lors de la mise en marche de l’appareil électroménager (et en fonction du programme sélectionné), l’outil de travail 11 et l’organe de mélange 50 sont entraînés simultanément en rotation et par le même arbre d’entrainement 12. The lid 10 is then placed on the preparation bowl 4 in order to close the internal volume and form the cooking zone. When the household appliance is switched on (and depending on the program selected), the working tool 11 and the mixing member 50 are rotated simultaneously and by the same drive shaft 12.
Nous allons décrire ci-après un procédé de fonctionnement de l’appareil électroménager 1. Lorsque l’utilisateur choisit le programme de cuisson à la vapeur, l’appareil électroménager est équipé du panier de cuisson 24 et de l’organe de mélange 50 monté dans le panier. L’outil de travail 11 est installé au fond du bol 4. Le procédé comprend une étape initiale de chauffe dans laquelle le dispositif de chauffage 43 est piloté pour atteindre une première puissance de chauffe pendant une première durée prédéterminée. Avantageusement, la puissance de chauffe est comprise entre 300 W et 500 W par exemple. Cette puissance permet d’amener l’eau contenue dans la cuve 41 à ébullition et d’obtenir une sortie de vapeur de l’ordre de 99° C. La vapeur emprunte son chemin de vapeur depuis la cuve 41 , vers la zone de cuisson (panier de cuisson 24, bol 4 et couvercle) via la canalisation 46 puis la sortie prévue dans le couvercle. La durée de chauffage prédéterminée pour cette étape initiale est par exemple comprise entre 10 et 20 min. We will describe below an operating method of the household appliance 1. When the user chooses the steam cooking program, the household appliance is equipped with the cooking basket 24 and the mixing member 50 mounted in the basket. The working tool 11 is installed at the bottom of the bowl 4. The method comprises an initial heating step in which the heating device 43 is controlled to reach a first heating power for a first predetermined duration. Advantageously, the heating power is between 300 W and 500 W for example. This power makes it possible to bring the water contained in the tank 41 to the boil and to obtain a steam output of around 99° C. The steam takes its steam path from the tank 41, towards the cooking zone (cooking basket 24, bowl 4 and lid) via pipe 46 then the outlet provided in the lid. The duration of predetermined heating for this initial step is for example between 10 and 20 min.
Le procédé comprend une étape secondaire de chauffe dans laquelle le dispositif de chauffage 43 est piloté pour atteindre une deuxième puissance de chauffe pendant une deuxième durée prédéterminée. La deuxième puissance de chauffe est ici inférieure à première puissance de chauffe. Avantageusement, la deuxième puissance de chauffe est comprise entre 100 W et 200 W. Cela permet d’obtenir une cuisson douce des aliments pour préserver tous leurs nutriments. La deuxième durée prédéterminée est ici supérieure à la première durée. Cependant, la deuxième durée prédéterminée peut être inférieure à la première durée prédéterminée. The method comprises a secondary heating step in which the heating device 43 is controlled to reach a second heating power for a second predetermined duration. The second heating power is here lower than the first heating power. Advantageously, the second heating power is between 100 W and 200 W. This allows the food to be cooked gently to preserve all its nutrients. The second predetermined duration is here greater than the first duration. However, the second predetermined duration may be less than the first predetermined duration.
Dans le présent exemple, le dispositif de chauffe est alimenté jusqu’à ce qu’il n’y ait plus d’eau dans la cuve 41. In this example, the heating device is powered until there is no more water in tank 41.
Le procédé de fonctionnement comprend également une étape de mélange dans laquelle l’organe de mélange 50 est également entraîné en rotation suivant plusieurs séquences de fonctionnement et après une condition de fonctionnement prédéterminée. En particulier, l’organe de mélange 50 est entraîné en rotation à chaque séquence de fonctionnement pendant une première période de temps prédéterminée et s’arrête (ou est immobilisé) pendant une deuxième période de temps prédéterminée. La première période de temps est inférieure à la deuxième période de temps. The operating method also includes a mixing step in which the mixing member 50 is also rotated following several operating sequences and after a predetermined operating condition. In particular, the mixing member 50 is rotated during each operating sequence for a first predetermined period of time and stops (or is immobilized) for a second predetermined period of time. The first time period is less than the second time period.
De manière avantageuse, mais non limitativement, la première période de temps est comprise entre 0.5 s et 5 s. La deuxième période de temps est comprise entre 15 s et 20 s. Advantageously, but not restrictively, the first period of time is between 0.5 s and 5 s. The second time period is between 15 s and 20 s.
Lors de ce séquençage, le moteur 13 fournit une puissance comprise entre 100 W et 150 W. L’organe de mélange 50 reçoit donc des impulsions. La vitesse de rotation de l’organe de mélange 50 est par exemple comprise entre 1000 et 3000 tr/min. Le nombre de séquence de fonctionnement dépend de la deuxième durée prédéterminée. Ce séquençage permet de ne pas écraser les aliments et de préserver la durée de vie du moteur 13. During this sequencing, the motor 13 provides a power of between 100 W and 150 W. The mixing member 50 therefore receives pulses. The rotation speed of the mixing member 50 is for example between 1000 and 3000 rpm. The number of operating sequences depends on the second predetermined duration. This sequencing prevents food from being crushed and preserves the life of motor 13.
De manière avantageuse, la condition de fonctionnement prédéterminée est l’écoulement d’une durée d’attente depuis le début de l’étape initiale. La durée d’attente est par exemple de 5 min à partir du début de l’étape initiale. De la sorte, l’organe de mélange 50 est entraîné en rotation de manière séquencée sur une partie de l’étape initiale et sur l’ensemble de l’étape secondaire, et ainsi jusqu’à la fin du programme de cuisson à la vapeur. Advantageously, the predetermined operating condition is the passage of a waiting time since the start of the initial step. The waiting time is example 5 min from the start of the initial stage. In this way, the mixing member 50 is rotated in a sequenced manner over part of the initial stage and over the entire secondary stage, and thus until the end of the steam cooking program. .
Lorsque l’utilisateur choisit le programme de mixage des aliments, l’appareil électroménager est équipé uniquement du bol 4 et de l’outil de travail 11. Dans ce cas, les aliments cuits avec le programme de cuisson à la vapeur et contenus dans le panier 24 sont versés directement dans le bol 4. Le procédé comprend une étape de mise en rotation de l’outil de travail pendant une durée prédéterminée. La vitesse de rotation de l’outil de travail peut être comprise entre 1000 tr/min et 3000 tr/min. When the user chooses the food mixing program, the household appliance is equipped only with the bowl 4 and the working tool 11. In this case, the food cooked with the steaming program and contained in the basket 24 are poured directly into the bowl 4. The method includes a step of rotating the working tool for a predetermined duration. The rotation speed of the work tool can be between 1000 rpm and 3000 rpm.
