Abstract
Description
La présente invention concerne un dispositif pour préparer des aliments sous forme d'émulsion tels que des blancs d'oeufs en neige ou de la crème fouettée. The present invention relates to a device for preparing food in the form of an emulsion such as egg whites or whipped cream.
L'invention vise également un appareil électro- ménager comprenant un tel dispositif. The invention also relates to a household appliance comprising such a device.
On connait de nombreux dispositifs permettant de battre des oeufs en neige ou de préparer de la crème fouettée. Many devices are known for beating eggs in snow or for preparing whipped cream.
Ces dispositifs comprennent un organe destiné à être monté en rotation dans un bol recevant l'aliment à préparer, cet organe comprenant un moyeu central auquel sont fixés plusieurs pales radiales. These devices include a member intended to be mounted in rotation in a bowl receiving the food to be prepared, this member comprising a central hub to which several radial blades are fixed.
Le bol des appareils connus est généralement plus haut que large et les pales de 1 'organe rotatif monté à l'intérieur de ce bol comprennent des branches allongées dans le sens de la hauteur du bol. On considere en effet que cette disposition est favorable pour faire "monter" suffisamment les blancs d'oeufs en neige et la creme fouettée. The bowl of known devices is generally taller than it is wide and the blades of the rotary member mounted inside this bowl include branches elongated in the height direction of the bowl. It is considered that this provision is favorable for sufficiently "raising" the egg whites and the whipped cream.
Pour assurer un brassage suffisant des aliments précités, les organes rotatifs sont généralement entraines à une vitesse de rotation superieure à 1000 t/mn. To ensure sufficient mixing of the aforementioned foods, the rotary members are generally driven at a speed of rotation greater than 1000 rpm.
Les appareils électroménagers du type robot comportent généralement plusieurs outils rotatifs interchangeables pour réaliser des opérations d'eminçage, rapage, brassage, etc. Certains de ces appareils sont équipés d'organes spécifiques pour battre les blancs d'oeufs en neige ou préparer de la crème fouettee. Toutefois, ces organes spécifiques s'avèrent peu efficaces et ne permettent pas d'obtenir des blancs d'oeufs en neige ayant la consistance optimale obtenue par les appareils cités au début de la présente description. Household appliances of the robot type generally include several interchangeable rotary tools for carrying out routing, grinding, brewing, etc. operations. Some of these devices are equipped with specific devices for beating the egg whites until stiff or for making whipped cream. However, these specific organs prove to be ineffective and do not make it possible to obtain egg whites in snow having the optimal consistency obtained by the devices mentioned at the beginning of this description.
On peut attribuer ce résultat médiocre au fait que les appareils du type robot comportent des bols relativement larges et peu hauts, de sorte qu'ils ne sont pas favorables pour faire "monter" les blancs d'oeufs en neige et la crème fouettée. This mediocre result can be attributed to the fact that the robot-type devices have relatively large bowls which are not very high, so that they are not favorable for "whipping" the egg whites and the whipped cream.
Le but de la présente invention est de remédier aux inconvénients des réalisations précitées, en creant un dispositif qui permette de preparer efficacement des aliments tels que des blancs d'oeufs en neige ou de la creme fouettée, même lorsque ce dispositif est utilisé dans un bol relativement large et peu haut. The object of the present invention is to remedy the drawbacks of the abovementioned embodiments, by creating a device which makes it possible to effectively prepare food such as egg whites or snow whipped cream, even when this device is used in a bowl. relatively wide and not very high.
Suivant l'invention, le dispositif pour préparer des aliments sous forme d'émulsion tels que des blancs d'oeufs en neige ou de la crème fouettée, comprenant un organe destiné à être monte en rotation dans un bol recevant l'aliment à préparer, cet organe comprenant un moyeu central auquel sont fixées plusieurs pales radiales, est carac térisé en ce que ces pales sont situées chacune dans un plan formant un certain angle avec l'axe du moyeu central, l'orientation de tet angle etant telle que lors de la rotation de l'organe, le bord de fuite des pales est le bord de celles-ci qui est le plus pres du fond du bol et en ce que les pales comprennent chacune plusieurs branches s'éten- dant sensiblement dans la direction radiale et définissant entre elles des ouvertures allongées dans cette direction radiale. According to the invention, the device for preparing food in the form of an emulsion such as egg whites or whipped cream, comprising a member intended to be mounted in rotation in a bowl receiving the food to be prepared, this member comprising a central hub to which several radial blades are fixed, is characterized in that these blades are each located in a plane forming a certain angle with the axis of the central hub, the orientation of this angle being such that during the rotation of the member, the trailing edge of the blades is the edge thereof which is closest to the bottom of the bowl and in that the blades each comprise several branches extending substantially in the radial direction and defining between them elongated openings in this radial direction.
La structure du dispositif conforme à l'invention est ainsi fondamentalement opposee à celle qui jusqu'à présent était considérée comme optimale pour battre les blancs d'oeufs en neige et la crème fouettée qui comprend des branches s'étendant suivant le sens de la hauteur du bol. The structure of the device according to the invention is thus fundamentally opposed to that which until now was considered to be optimal for beating the egg whites in snow and the whipped cream which comprises branches extending in the direction of the height from the bowl.
De plus, le sens de rotation des rotors à pâles destines à monter les blancs est tel que le liquide contenu dans le bol tend à monter. Or, contrairement à l'idée reçue, le sens de rotation de la présente réalisation est inverse, c'est-à-dire que le liquide tend à être plaqué au fond du bol-. In addition, the direction of rotation of the paddle rotors intended to mount the whites is such that the liquid contained in the bowl tends to rise. However, contrary to popular belief, the direction of rotation of the present embodiment is opposite, that is to say that the liquid tends to be pressed against the bottom of the bowl.
Alors que la structure du dispositif selon l'invention, pouvait être considérée comme défavorable, on a constaté de façon surprenante qu'il permettait d'obtenir des aliments ayant une excellente consistance, même lorsque le dispositif est utilisé en tant qu'accessoire d'un robot ménager à bol large et peu haut. While the structure of the device according to the invention could be considered unfavorable, it has surprisingly been found that it makes it possible to obtain foods having an excellent consistency, even when the device is used as an accessory. a food processor with a large, low bowl.
Selon une version préférée de l'invention, l'angle des pales est sensiblement égal à 45". According to a preferred version of the invention, the angle of the blades is substantially equal to 45 ".
De préférence, le dispositif comprend trois pales régulièrement réparties autour du moyeu et chaque pale comprend trois branches parallèles définissant entre elles deux ouvertures sensiblement rectangulaires. Preferably, the device comprises three blades regularly distributed around the hub and each blade comprises three parallel branches defining between them two substantially rectangular openings.
Toutes ces dispositions se sont révélées avantageuses à l'égard des qualités du produit alimentaire à préparer. All these provisions have proved advantageous with regard to the qualities of the food product to be prepared.
D'autres particularités et avantages de l'invention appara3tront encore dans la description ci-après. Other features and advantages of the invention will become apparent in the description below.

- Figure 4 is an elevational view in section along the plane IV-IV of Figure 2.
A la figure 1, on a représente un robot électroménager comprenant un bloc motoreducteur 1 sur lequel est disposé un bol 2 destiné à recevoir un aliment à brasser, émincer, râper, etc. A l'intérieur de ce bol 2 est monté en rotation un organe 3 interchangeable qui, dans le cas représenté, est destiné spécifiquement à la préparation des blancs d'oeufs en neige ou de la crème fouettée. In Figure 1, there is shown a household appliance comprising a geared motor unit 1 on which is placed a bowl 2 intended to receive a food to be brewed, minced, grated, etc. Inside this bowl 2 is mounted in rotation an interchangeable member 3 which, in the case shown, is specifically intended for the preparation of egg whites or snow whipped cream.
L'organe rotatif 3 comprend un moyeu central 4 auquel sont fixées plusieurs pales radiales 5. The rotary member 3 comprises a central hub 4 to which several radial blades 5 are fixed.
Conformément à l'invention, ces pales 5 sont situées chacune (voir figures 2, 3 et 4) dans un plan formant un angle a sensiblement égal à 45 avec l'axe X-X' du moyeu central 4, l'orientation de cet angle a étant telle que lors de la rotation de l'organe 3 (voir fleches F sur les figures 2 et 4), le bord de fuite 6 des pales 5 est le bord de celles-ci qui est le plus pres du fond 7 du bol 2. According to the invention, these blades 5 are each located (see Figures 2, 3 and 4) in a plane forming an angle a substantially equal to 45 with the axis XX 'of the central hub 4, the orientation of this angle a being such that during the rotation of the member 3 (see arrows F in FIGS. 2 and 4), the trailing edge 6 of the blades 5 is the edge of the latter which is closest to the bottom 7 of the bowl 2 .
Par ailleurs, les pales 5 comprennent chacune plusieurs branches s'étendant sensiblement dans la direction radiale et définissant entre elles des ouvertures allongées 11, 12 dans cette direction radiale. Furthermore, the blades 5 each comprise several branches extending substantially in the radial direction and defining between them elongate openings 11, 12 in this radial direction.
Dans l'exemple représenté, l'organe rotatif 3 comprend trois pales 5 régulièrement réparties autour du moyeu 4. In the example shown, the rotary member 3 comprises three blades 5 regularly distributed around the hub 4.
Chaque pale 5 comprend trois branches 8, 9, 10 parallèles définissant entre elles deux ouvertures 11, 12 sensiblement rectangulaires. Each blade 5 comprises three parallel branches 8, 9, 10 defining between them two substantially rectangular openings 11, 12.
La section transversale des branches 9, 10 est carre, tandis que celle de la branche 8 présentant le bord de fuite 6 est triangulaire, de sorte que ce dernier présente une arete vive. The cross section of the branches 9, 10 is square, while that of the branch 8 having the trailing edge 6 is triangular, so that the latter has a sharp edge.
Par ailleurs, le bord d'attaque 13 de chaque pale 5 comprend à la périphérie de celle-ci une aile évidée 14 de forme sensiblement triangulaire dont l'hypothenuse est confondue avec la branche radiale 10 correspondant à ce bord d'attaque 13 et dont le sommet 15 est situé en arrière du bord d'attaque 13 relativement au sens F de la rotation de la pale. Furthermore, the leading edge 13 of each blade 5 comprises, at the periphery thereof, a hollowed-out wing 14 of substantially triangular shape, the assumption of which coincides with the radial branch 10 corresponding to this leading edge 13 and whose the apex 15 is located behind the leading edge 13 relative to the direction F of the rotation of the blade.
De plus, l'aile évidée est située dans le plan général de la pale 5 et est délimitée par des parties de branches de même section que les branches 9, 10 sensiblement radiaTes de la pale. In addition, the hollowed-out wing is situated in the general plane of the blade 5 and is delimited by parts of branches of the same section as the branches 9, 10 which are substantially radiate from the blade.
Par ailleurs, l'extrémité de chaque pale 5 opposée au moyeu 4 est sensiblement en forme d'arc d'ellipse 16 adaptee pour pouvoir suivre de tres près la surface interieure du bol 2. Cet arc d'ellipse 16 s'étend sans discontinuité a l'extrémité des branches 8, 9, 10 et de l'aile évidée 14. Furthermore, the end of each blade 5 opposite the hub 4 is substantially in the shape of an elliptical arc 16 adapted to be able to follow very closely the interior surface of the bowl 2. This elliptical arc 16 extends without discontinuity at the end of the branches 8, 9, 10 and of the hollowed-out wing 14.
L'épaisseur des branches 8, 9, 10, 14 est de l'ordre de 2 à 3 mm. La largeur des pales 5 est comprise entre environ 30 et 70 mm, tandis que leur longueur est de l'ordre de 70 à 90 mm. L'ensemble de l'organe rotatif 3 peut être réalisé par moulage en matière plastique. The thickness of the branches 8, 9, 10, 14 is of the order of 2 to 3 mm. The width of the blades 5 is between approximately 30 and 70 mm, while their length is of the order of 70 to 90 mm. The entire rotary member 3 can be produced by plastic molding.
Un tel organe rotatif 3 peut être monté dans le bol 2 d'un robot électroménager. La forme d'un tel bol 2 (relativement large et peu haute) est normalement adaptée au brassage, à l'minage ou au râpage des aliments au moyen d'organes rotatifs appropriés. Such a rotary member 3 can be mounted in the bowl 2 of a household appliance. The shape of such a bowl 2 (relatively wide and not very high) is normally suitable for stirring, blasting or grating food by means of suitable rotary members.
Le moyeu central 4 de l'organe 3 comporte à cet effet un evidement axial 17 (voir figure 3) destiné à être engagé sur l'arbre de sortie de forme complémentaire du bloc moto-reducteur 1. La vitesse de rotation de l'organe 3 est normalement comprise entre 500 et 600 t/mn. Cette vitesse de rotation est faible par rapport à celle utilise dans les appareils connus spécifiquement destinés à la préparation des blancs d'oeufs en neige et de la crème fouettée. The central hub 4 of the member 3 has for this purpose an axial recess 17 (see FIG. 3) intended to be engaged on the output shaft of complementary shape of the geared motor block 1. The speed of rotation of the member 3 is normally between 500 and 600 rpm. This rotation speed is low compared to that used in known devices specifically intended for the preparation of egg whites and snow and whipped cream.
Malgré cette faible vitesse de rotation et la forme defavorable du bol 2, l'organe 3 que l'on vient de décrire permet d'obtenir en quelques secondes des blancs en neige et de la creme fouettée ayant des qualités nettement améliorées.Despite this low speed of rotation and the unfavorable shape of the bowl 2, the member 3 that has just been described makes it possible to obtain snowy whites and whipped cream in a few seconds having markedly improved qualities.
Ce résultat surprenant est engendre par la structure particuliere et originale des pales 5 et le sens de rotation adopté qui s' avèrent favorables pour la mise en émulsion et la "montée" des blancs d'oeufs et des cremes fouettees. Sans que l'invention soit liee à cette explication, on peut à cet égard avancer que les caracteristiques suivantes contribuent à l'obtention du resultat surprenant ci-dessus
- le fait que les pales soient inclinées à 45" ass-re un brassage efficace et une introduction d'air opti m,e dans la preparation alimentaire,
- le fait que ces pales soient largement ajourées évite à celles-ci d'être trop freinées dans leur rotation,
- la section des bras radiaux permet du fait de la dépression engendrée à l'arrière de ceux-ci lors de la rotation, d'introduire de l'air dans la preparation favorable à la mise en emulsion de celle-ci,
- les ailes évidées disposées sur la partie peri- phérique des pales permettent de-brasser efficacement et ramener vers le fond du bol la portion de la préparation qui tend à monter le long des parois latérales du bol.This surprising result is generated by the particular and original structure of the blades 5 and the direction of rotation adopted which are favorable for the emulsification and the "rise" of the egg whites and whipped creams. Without the invention being linked to this explanation, it can be argued in this regard that the following characteristics contribute to obtaining the surprising result above
- the fact that the blades are inclined at 45 "ass-re efficient mixing and introduction of air optimi m, e in food preparation,
- the fact that these blades are largely perforated prevents them from being too braked in their rotation,
- the section of the radial arms makes it possible, owing to the vacuum generated at the rear of the latter during rotation, to introduce air into the preparation favorable for emulsification thereof,
- the hollowed out wings arranged on the peripheral part of the blades make it possible to efficiently stir and bring back towards the bottom of the bowl the portion of the preparation which tends to rise along the side walls of the bowl.
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment which has just been described and many modifications can be made to it without departing from the scope of the invention.
