Description
La présente invention concerne le domaine technique des appareils ménagers de découpe, manuels ou motorisés, également appelés mandolines, utilisés pour découper des aliments, notamment en tranches ou en filaments, par un mouvement alternatif d'un outil de coupe.The present invention relates to the technical field of household cutting devices, manual or motorized, also called mandolins, used to cut food, including slices or filaments, by reciprocating a cutting tool.
Un
Ainsi, il est apparu le besoin d'un appareil ménager de type mandoline dont le système de manoeuvre de l'outil de coupe soit moins encombrant et présente un fonctionnement plus équilibré afin de réduire les bruits de fonctionnement et l'usure des pièces en mouvement.Thus, it has emerged the need for a mandolin-type home appliance whose cutting tool operating system is less bulky and has a more balanced operation to reduce operating noise and wear of moving parts. .
Afin d'atteindre cet objectif, l'invention concerne un appareil de découpe d'aliments comprenant :
- un châssis délimitant une zone de coupe,
- un outil de coupe mobile par rapport au châssis au moins dans la zone de coupe, selon un mouvement alternatif rectiligne dans un plan de coupe,
- des moyens de manoeuvre de l'outil de coupe mobile, qui comprennent un système de transmission entraînant l'outil de coupe.
- a frame delimiting a cutting zone,
- a cutting tool movable relative to the frame at least in the cutting area, in reciprocating rectilinear motion in a cutting plane,
- means for operating the movable cutting tool, which comprise a transmission system driving the cutting tool.
Selon l'invention, le système de transmission comprend :
- une couronne de sortie fixe présentant un axe principal,
- un pignon satellite de sortie qui engrène la couronne de sortie fixe et qui porte une conformation cylindrique d'entraînement de l'outil de coupe,
- un plateau de transmission qui est mobile en rotation selon l'axe principal et qui porte un axe décentré de rotation du pignon satellite de sortie,
- a fixed output ring having a main axis,
- a satellite output gear which meshes with the fixed output ring and which carries a cylindrical driving configuration of the cutting tool,
- a transmission plate which is rotatable along the main axis and which carries an off-axis axis of rotation of the output planet pinion,
Un tel mode de réalisation permet de réduire les frottements au niveau de la liaison glissière assurant l'entraînement de l'outil de coupe, de sorte qu'il n'est pas nécessaire de mettre en oeuvre un ou plusieurs roulements à bille au niveau de cette liaison glissière. Cette cinématique évite aussi les risques d'arc-boutement et donc de blocage des moyens de manoeuvre pendant la découpe des aliments. Cette cinématique réduit également le porte-à-faux au niveau de la transmission des efforts des moyens de manoeuvre vers l'outil de coupe, ce qui induit un meilleur rendement que celui des systèmes selon l'art antérieur, de sorte qu'il est possible de réduire la puissance du moteur pour une puissance disponible au niveau de l'outil de coupe équivalente à celle des appareils selon l'art antérieur. Par ailleurs, cette cinématique permet de réduire fortement l'encombrement du système de transmission par rapport aux systèmes à bielle et roue à excentrique.Such an embodiment makes it possible to reduce the friction at the sliding connection ensuring the driving of the cutting tool, so that it is not necessary to use one or more ball bearings at the level of the this slide link. This kinematics also avoids the risk of jamming and thus blocking maneuvering means during the cutting of food. This kinematics also reduces the cantilever at the level of the transmission of the forces of the operating means towards the cutting tool, which induces a better efficiency than that of the systems according to the prior art, so that it is it is possible to reduce the power of the motor for a power available at the level of the cutting tool equivalent to that of the apparatus according to the prior art. Moreover, this kinematics makes it possible to reduce greatly the size of the transmission system compared to systems with rod and eccentric wheel.
Avantageusement, la conformation cylindrique entraîne en translation un organe d'entraînement monté dans le châssis et l'outil de coupe est en prise avec l'organe d'entraînement. Ainsi l'outil de coupe n'est pas en prise directe avec la conformation cylindrique.Advantageously, the cylindrical conformation drives in translation a drive member mounted in the frame and the cutting tool is engaged with the drive member. Thus the cutting tool is not in direct contact with the cylindrical conformation.
Selon une caractéristique de l'invention, le système de transmission comprend un réducteur entraînant le plateau de transmission.According to one characteristic of the invention, the transmission system comprises a gearbox driving the transmission plate.
Selon une variante de cette caractéristique, le réducteur comprend :

- a fixed entry crown,
- an input satellite pinion which meshes with the input sun gear and the fixed input ring,
- the transmission plate being interposed between the fixed input ring and the fixed output ring and carrying another off-center axis of rotation of the input satellite pinion.
La mise en oeuvre d'un tel réducteur épicycloïdal permet d'adapter la vitesse de rotation du plateau de transmission avec un encombrement réduit.The use of such an epicyclic reduction gear makes it possible to adapt the speed of rotation of the transmission plate with a small space requirement.
Avantageusement la couronne d'entrée fixe et la couronne de sortie fixe forment un ensemble monobloc.Advantageously, the fixed input ring and the fixed output ring form a one-piece assembly.
Selon une caractéristique de l'invention, les composants du système de transmission sont enfermés dans un carter proximal situé du côté de la conformation cylindrique et un carter distal situé à l'opposé du carter proximal par rapport au plateau de transmission, le carter proximal et le carter distal étant liés rigidement l'un à l'autre.According to a feature of the invention, the components of the transmission system are enclosed in a proximal housing located on the side of the cylindrical conformation and a distal housing located opposite the proximal housing relative to the transmission plate, the proximal housing and the distal housing being rigidly connected to each other.
Selon une variante de cette caractéristique, le carter proximal comprend une fenêtre rectiligne de passage de la conformation cylindrique.According to a variant of this characteristic, the proximal casing comprises a rectilinear window of passage of the cylindrical conformation.
Selon une caractéristique de l'invention, l'axe principal, l'axe de rotation du pignon satellite de sortie et l'axe de la conformation cylindrique d'entraînement sont alignés lors du montage du système de transmission.According to a characteristic of the invention, the main axis, the axis of rotation of the output satellite pinion and the axis of the cylindrical drive conformation are aligned during assembly of the transmission system.
Selon l'invention, le système de transmission peut être intégré de manière permanente au châssis ou au contraire être adapté sur ce dernier de manière à être facilement démontable.According to the invention, the transmission system can be permanently integrated into the chassis or on the contrary be adapted to the latter so as to be easily removable.
Ainsi selon une forme de réalisation de l'appareil de découpe selon l'invention, le système de transmission est logé dans un bloc de transmission adapté de manière amovible sur un couvercle.Thus according to one embodiment of the cutting apparatus according to the invention, the transmission system is housed in a transmission block removably adapted to a cover.
Selon une caractéristique de cette forme de réalisation, le couvercle comprend des moyens de fixation par emboitement du bloc de transmission.According to a characteristic of this embodiment, the cover comprises attachment means by interlocking the transmission block.
Selon l'invention, les moyens de manoeuvre peuvent comprendre un moteur électrique intégré au châssis ou au couvercle. Les moyens de manoeuvre peuvent aussi comprendre un moteur électrique appartenant à un bloc moteur amovible. Les moyens de manoeuvre peuvent aussi être entraînés par un moteur électrique appartenant à un bloc moteur indépendant de l'appareil de découpe d'aliments.According to the invention, the operating means may comprise an electric motor integrated in the frame or the cover. The operating means may also comprise an electric motor belonging to a removable engine block. The operating means can also be driven by an electric motor belonging to a motor unit independent of the food cutting apparatus.
Ainsi selon une forme de réalisation de l'appareil de découpe selon l'invention, les moyens de manoeuvre comprennent un moteur électrique entraînant le système de transmission.Thus according to one embodiment of the cutting apparatus according to the invention, the operating means comprise an electric motor driving the transmission system.
Selon une variante de cette caractéristique, le moteur électrique est logé dans un bloc moteur amovible.According to a variant of this characteristic, the electric motor is housed in a removable engine block.
Selon une autre variante de cette caractéristique, le bloc moteur est adapté de manière amovible sur le bloc de transmission.According to another variant of this characteristic, the motor unit is removably fitted on the transmission block.
Selon une autre caractéristique de cette forme de réalisation, le bloc moteur est adapté pour entrainer au moins un autre accessoire ménager que le bloc de transmission, par exemple un fouet ou un pied mixer.According to another characteristic of this embodiment, the engine block is adapted to drive at least one other household accessory that the transmission block, for example a whip or a mixer foot.
Selon une autre forme de réalisation de l'appareil de découpe selon l'invention, les moyens de manoeuvre sont intégrés au châssis et comprennent un moteur électrique entraînant le système de transmission.According to another embodiment of the cutting apparatus according to the invention, the operating means are integrated in the frame and comprise an electric motor driving the transmission system.
Avantageusement alors, le moteur électrique entraîne le réducteur.Advantageously then, the electric motor drives the reducer.

L'appareil de découpe d'aliments illustré aux
L'appareil de découpe d'aliments comprend également une goulotte 5 d'introduction d'aliments à découper qui est solidaire du châssis 1 et se trouve située au-dessus de la zone de coupe 4. Selon l'exemple illustré, la goulotte 5 est intégrée à un couvercle 6 amovible qui peut être complètement retiré du châssis 1 de manière à libérer l'accès à la partie supérieure du châssis 1 et de la tête 3, comme le montre la
Afin de permettre la découpe des aliments introduits dans la goulotte 5, l'appareil comprend au moins un outil de coupe 10; 10'; 10" mobile par rapport au châssis 1 au moins dans la zone de coupe 4 selon un mouvement alternatif rectiligne dans un plan de coupe C. Dans l'exemple de réalisation illustré, les outils de coupe 10; 10'; 10" sont interchangeables et sont amovibles par rapport au châssis 1.In order to allow the cutting of the feed introduced into the
Afin d'assurer la stabilité du couvercle 6 lors de la mise en oeuvre de l'appareil de découpe d'aliments, le couvercle 6 peut être placé dans une position verrouillée sur le châssis 1, illustrée
Le couvercle 6 peut occuper une position verrouillée sur le châssis 1, dans laquelle le couvercle 6 couvre la zone de coupe 4 et l'outil de coupe 10 ; 10' ; 10", de manière à ce que ceux-ci ne soient pas accessibles par le dessus de l'appareil.The
Selon une forme de réalisation, l'outil de coupe 10 mobile dans la zone de coupe 4 est associé à un outil de coupe complémentaire 11 est fixe par rapport au châssis 1. L'outil de coupe complémentaire 11 est situé dans la zone de coupe 4 sous la goulotte 5 de manière à ce que l'outil de coupe 10 se déplace entre la goulotte 5 et l'outil de coupe complémentaire 11. L'outil de coupe 10 est, dans le cas présent, mobile en translation selon une direction D sensiblement normale à la direction Δ d'extension de la goulotte 5. Selon l'exemple illustré, l'outil de coupe 10 et l'outil de coupe complémentaire 11 sont amovibles.According to one embodiment, the cutting
L'outil de coupe complémentaire 11 comprend, comme le montrent plus particulièrement les
L'outil de coupe 10 comprend un corps 22 pourvu de deux rainures latérales 23 destinées à venir s'engager sur deux languettes longitudinales 24 portées par le corps 12 de l'outil de coupe complémentaire 11, de sorte que l'outil de coupe 10 et l'outil de coupe complémentaire 11 sont liés l'un à l'autre par une liaison glissière assurant le guidage de l'outil de coupe 10 lors de ses mouvements alternatifs. Dans le cas présent, l'outil de coupe 10 et l'outil de coupe complémentaire 11 sont solidaires et forment un ensemble adapté de manière amovible sur le châssis 1.The cutting
Le corps 22 porte une lame 25 qui se trouve à l'avant d'une partie pleine 26 du corps 22 et à l'arrière d'une fenêtre de coupe 27 délimitée par le corps 22. La lame 25 comprend une arrête de coupe principale 28 située dans un plan de coupe C. Dans le cas présent, le plan de coupe C est sensiblement normal à la direction Δ d'extension de la goulotte 5.The
L'outil de coupe 10 comprend également un sabot presseur 29 qui est issu de l'arrête de coupe principale 28 et agencé du côté de l'outil de coupe complémentaire 11. Le sabot presseur 29 comprend un biseau 30 incliné à partir de l'arrête de coupe principale 28 vers l'intérieur de l'outil de coupe 10 et dans une direction opposée au sens de travail indiqué par la flèche F1. Selon l'exemple illustré le biseau 30 se prolonge par un talon 31 sensiblement parallèle au plan de coupe C. Le sabot presseur 29 possède, selon l'exemple illustré, une épaisseur h suffisante pour occuper la majeure partie de l'espace situé entre l'outil de coupe complémentaire 11 et l'extrémité inférieure de la goulotte 5. L'épaisseur h, mesurée entre le plan de coupe et l'extrémité du biseau 30 opposée à l'arrête de coupe principale 28, est, de préférence, supérieure ou égale à 4 mm.The cutting
L'appareil de découpe d'aliments comprend des moyens de manoeuvre 36 de l'outil de coupe 10 mobile. Les moyens de manoeuvre 36 sont adaptés pour assurer un déplacement de l'outil de coupe 10 selon un mouvement alternatif de translation rectiligne dans un sens de travail indiqué par la flèche F1 et dans un sens de retour indiqué par la flèche F2.The food cutting apparatus comprises operating means 36 of the
Le corps 22 de l'outil de coupe 10 comprend, au niveau d'une partie arrière, un organe d'accouplement 35 avec les moyens de manoeuvre 36. L'outil de coupe 10 se déplace alors entre :
- une position de repos R, représentée en traits pleins à la
figure 2 , dans laquelle l'arrête de coupe principale 28 est située en amont de la zone de coupe 4, par référence au sens de travail indiqué par la flèche F1, - et une position d'extension E, symbolisée en traits discontinus à la
figure 2 , dans laquelle l'arrête de coupe principale 28 est située en aval de la zone de coupe 4, par référence au sens de travail indiqué par la flèche F1.
- a rest position R, represented in solid lines at the
figure 2 , in which themain cutting edge 28 is located upstream of the cutting zone 4, with reference to the direction of work indicated by the arrow F1, - and an extension position E, symbolized in broken lines at the
figure 2 , in which themain cutting edge 28 is located downstream of the cutting zone 4, with reference to the direction of work indicated by the arrow F1.
L'outil de coupe 10 est ainsi mobile par rapport au châssis 1 au moins dans la zone de coupe 4, selon un mouvement alternatif dans le plan de coupe C.The cutting
Selon l'exemple illustré, les moyens de manoeuvre 36 sont intégrés au châssis 1. Les moyens de manoeuvre 36 sont motorisés et comprennent un organe d'entraînement 37 complémentaire de l'organe d'accouplement 35 de l'outil de coupe 10. Dans le cas présent, l'organe d'entraînement 37 des moyens de manoeuvre 36 comprend un chariot 37a guidé en translation qui porte un ergot 37b destiné à venir s'engager dans un alésage complémentaire de l'organe d'accouplement 35 de l'outil de coupe 10. Les moyens de manoeuvre 36 comprennent, par ailleurs, un moteur électrique 38 dont un arbre 43 de sortie entraîne un système de transmission 40 adapté pour assurer un déplacement rectiligne alternatif à l'organe d'entraînement 37.According to the illustrated example, the operating means 36 are integrated in the
Selon une forme de réalisation de l'invention, et comme le montre la
Plus particulièrement dans l'exemple de réalisation illustré sur la
Le système de transmission 40 comprend en outre en sortie un train épicycloïdal 57 comprenant une couronne de sortie fixe 51 coaxiale à l'axe principal Ω et donc coaxiale à la couronne d'entrée fixe 46.The transmission system 40 further comprises at the output an
Le plateau de transmission 48 est interposé entre la couronne d'entrée fixe 46 et la couronne de sortie fixe 51 et porte un autre axe décentré 49 de rotation du pignon satellite d'entrée 47. L'axe décentré 53 et l'autre axe décentré 49 sont agencés sur deux faces opposées du plateau de transmission 48. Le pignon satellite d'entrée 47 présente un alésage central 50 recevant l'autre axe décentré 49 du plateau de transmission 48.The
Selon l'exemple illustré, la couronne de sortie fixe 51 est liée de manière rigide à la couronne d'entrée fixe 46 et comprend une denture sur sa surface interne périphérique. La couronne d'entrée fixe 46 et la couronne de sortie fixe 51 forment, selon l'exemple illustré, un ensemble monobloc 58 qui est rapporté dans le carter distal 41 et sur lequel vient s'emboîter le carter proximal 42. Cet ensemble monobloc 58 comprend alors une nervure périphérique 59 située entre la couronne d'entrée fixe 46 et la couronne de sortie fixe 51 qui définit un palier de guidage en rotation du plateau de transmission 48.According to the illustrated example, the fixed
Le système de transmission 40 comprend aussi un pignon satellite de sortie 52 qui est guidé en rotation sur lui-même par l'axe décentré 53 porté par le plateau de transmission 48. Ainsi le plateau de transmission 48 porte l'axe décentré 53 de rotation du pignon satellite de sortie 52. Le pignon satellite de sortie 52 porte, sur sa face opposée au plateau de transmission 48, une conformation cylindrique 54 d'entraînement de l'organe d'entraînement 37 des moyens de manoeuvre 36.The transmission system 40 also comprises a
Selon l'exemple illustré la conformation cylindrique 54 est formée par un ergot cylindrique et s'étend à l'extérieur du carter proximal 42 par une fenêtre 56 rectiligne qui s'étend selon un diamètre de la couronne de sortie fixe 51.According to the illustrated example the
De manière à ce que la conformation cylindrique 54 se déplace en translation, la couronne de sortie fixe 51 présente un diamètre D51 qui est sensiblement égal au double du diamètre D52 du pignon satellite de sortie 52, comme illustré de manière schématique par la
Ainsi, lors du fonctionnement du moteur électrique 38 la conformation cylindrique 54 se déplace en translation alternative le long du diamètre d de la couronne de sortie fixe 51.Thus, during the operation of the
A titre de variante, tel que représenté sur la
La mise en marche et l'arrêt du moteur électrique 38 sont assurés au moyen d'un bouton poussoir 60 placé sur le couvercle 6 amovible. Le bouton-poussoir 60 est adapté pour actionner une tige 61 de commande d'un interrupteur située sous le couvercle 6 lorsque celui-ci est en place. La tige 61 est disposée dans un alésage 62 de la tête 3 de manière à affleurer au niveau d'une surface supérieure de ladite tête 3. Par ailleurs, l'alésage 62 présente des dimensions suffisamment petites pour empêcher une manoeuvre de la tige 61 avec un doigt. Dans le cas d'un alésage 62 cylindrique de révolution, le diamètre de ce dernier sera de préférence inférieur à 1 cm. Le diamètre de l'alésage 62 est par exemple de 6,5 mm. Ainsi, dans la mesure où la tige 61 affleure et compte tenu des dimensions de l'alésage 62, il n'est pas possible d'actionner la tige 61 pour commander le fonctionnement du moteur électrique 38 sans que le couvercle 6 ne soit convenablement positionné sur la tête 3. Cette disposition limite les risques de blessures qui résulteraient d'une mise en mouvement de l'outil de coupe 10 mobile alors que le couvercle 6 ne serait pas en place.The starting and stopping of the
L'appareil de découpe d'aliments selon l'invention, ainsi constitué, est mis en oeuvre de la manière suivante.The food cutting apparatus according to the invention, thus constituted, is implemented in the following manner.
L'utilisateur sélectionne par exemple l'ensemble formé par l'outil de coupe 10 et l'outil de coupe complémentaire 11 et le place dans la tête 3 du châssis 1, comme le montre la
L'arbre 43 du moteur électrique 38 entraîne le plateau de transmission 48 du réducteur 44 par l'intermédiaire du pignon planétaire d'entrée 45 et du pignon satellite d'entrée 47. Le pignon satellite de sortie 52 monté sur l'axe décentré du plateau de transmission 48 est alors entraîné en rotation dans la couronne de sortie fixe 51. La conformation cylindrique 54 porté par le pignon satellite de sortie 52 circule alors linérairement dans la fenêtre 56 pour entraîner l'organe d'entraînement 37 en prise avec l'outil de coupe 10 mobile.The
L'appareil de découpe d'aliments équipé du système de transmission 40 selon l'invention présente ainsi une transmission efficiente et compacte.The food cutting apparatus equipped with the transmission system 40 according to the invention thus has an efficient and compact transmission.
Les aliments à découper sont introduits dans la goulotte 5 pour y être poussés au moyen d'un poussoir 70. A titre d'exemple, la
Lorsque l'extrémité inférieure de la pomme de terre arrive dans la zone de coupe 4, elle vient en appui contre les organes de coupe 13 de l'outil de coupe complémentaire 11. Lors de son déplacement dans le sens de travail indiqué par la flèche F1, l'arrête de coupe principale 28 de l'outil de coupe 10 tranche la partie de la pomme de terre se trouvant dans la zone de coupe 4 entre l'outil de coupe complémentaire 11 et le plan de coupe C. Au fur et à mesure de l'avancement de l'outil de coupe 10, le biseau 30 presse la partie découpée contre les organes de coupe 13 de l'outil de coupe complémentaire 11 de sorte que la partie découpée se trouve tranchée parallèlement à la direction Δ d'extension et donc divisée en bâtonnets qui viennent se placer entre les organes de coupe 13. Les bâtonnets ainsi découpés seront alors expulsés lors du prochain passage de l'outil de coupe 10.When the lower end of the potato reaches the cutting zone 4, it bears against the cutting
Il est à noter que le talon 31 du sabot presseur 29 contribue à assurer un parfait engagement des bâtonnets entre les organes de coupe 13.It should be noted that the
Par ailleurs, afin d'éviter que la partie découpée ne suive la translation de l'outil de coupe 10, l'outil de coupe complémentaire 11 comprend de préférence une butée 71 d'appui qui s'étend transversalement au plan de coupe C et se trouve sensiblement en regard de l'arrêt de coupe principale 28. Selon l'exemple illustré, la butée 71 est mobile entre une position de travail T, illustrée en traits pleins à la
Il apparaît donc que l'appareil équipé de l'outil de coupe 10 mobile et de l'outil de coupe complémentaire 11 fixe permet de réaliser la découpe d'un aliment en bâtonnets en un seul passage.It therefore appears that the apparatus equipped with the
Selon l'exemple de réalisation de l'outil de coupe complémentaire 11 décrit en relation avec les
La
Selon cette forme de réalisation, l'outil de coupe 10 comprend une deuxième arrête de coupe principale 75 sensiblement parallèle au plan de coupe C et disposée pour travailler dans le sens de retour indiqué par la flèche F2. La deuxième arrête de coupe principale 75 est également associée à un autre sabot presseur 76 qui comprend un autre biseau 77 incliné dans un sens opposé à celui du biseau 30 du sabot presseur 29 associé à la première arrête de coupe principale 28.According to this embodiment, the cutting
Toujours selon cette forme de réalisation, l'outil de coupe complémentaire 11 comprend une deuxième butée 78 qui comme la butée 71 est mobile entre une position de travail T et une position de retrait A. La deuxième butée 78 peut être réalisée comme la butée 71.Still according to this embodiment, the
La
Par ailleurs, l'appareil de découpe d'aliments selon l'invention n'est pas nécessairement utilisé avec un outil de coupe 10 mobile et un outil de coupe complémentaire 11 fixe. En effet, l'appareil de découpe d'aliments selon l'invention peut être utilisé avec un seul outil de coupe mobile. Ainsi, la
Par ailleurs, selon l'exemple de réalisation décrit en relation avec les
Ainsi, la
Selon cette variante, le tronc 2 du châssis 1 est creux de manière à former un récipient destiné à recevoir les aliments découpés au niveau de la tête 3 qui est adaptée de manière amovible sur le tronc 2. La tête 3 est destinée à recevoir les outils de coupe 10 ; 10' ; 10" tels que décrits précédemment en relation avec les
Le bloc moteur 100 peut être de toute nature appropriée et, par exemple être formé par un bloc moteur destiné à entrainer ou équiper différents types d'accessoires comme par exemple un pied mixer ou encore un fouet.The
Afin de permettre la mise en place des moyens de manoeuvre 36, le couvercle 6 comprend des moyens de fixation 102 qui, selon l'exemple illustré, présentent une forme creuse 103 complémentaire d'une partie inférieure 104 du bloc de transmission 101 de manière à ce que ce dernier s'y emboite en partie et s'y trouve immobilisé au moins en translation dans un plan parallèle à la direction d'emboîtement. Selon l'exemple illustré, la forme creuse 103 est aménagée en partie au moins dans le couvercle 6 pour former les moyens de fixation 102 par emboîtement du bloc de transmission 101.In order to allow the establishment of the operating means 36, the
Par ailleurs, selon l'exemple de réalisation décrit en relation avec les
A titre de variante, les moyens de manoeuvre 36 ne comprennent pas nécessairement un moteur électrique 38 intégré à l'appareil de découpe d'aliments. L'appareil de découpe d'aliments peut comporter un système de transmission 40 associé à un bloc moteur indépendant du châssis et du couvercle, l'appareil de découpe d'aliments formant alors un accessoire utilisé avec le bloc moteur.As a variant, the operating means 36 do not necessarily include an
La présente invention n'est nullement limitée aux exemples de réalisation décrits et à leurs variantes, mais englobe de nombreuses modifications dans le cadre des revendications.The present invention is in no way limited to the described exemplary embodiments and their variants, but encompasses many modifications within the scope of the claims.
