Description
La séparation hermétique du bol de travail surtout par rapport au
<EMI ID=1.1>
de la construction de mixers. Des mesures constructives spéciales sont surtout nécessaires à l'endroit où l'arbre de commande pour l'outil de coupe pénètre dans le bol de travail. Les garnitures qui y sont prévues ne sont généralement pas parfaites et sont soumises à une usure relativement forte et à un vieillissement rapide.
Pour cette raison, la présente Invention prévoit la transmission d'énergie du moteur vers l'outil de coupe par champs électriques et/ou magnétiques, le bol de travail étant séparé hermétiquement du carter du moteur.
Lorsque la transmission énergétique a lieu par champs magnétiques, on attache de préférence un aimant permanent sur l'induit du moteur. Sur le prolongement de l'axe du moteur, dans le bol de travail, se trouve un pivot, sur lequel se trouve une armature en fer ou également un aimant permanent,
<EMI ID=2.1>

l'entrefer soit le plus réduit possible;pour que le' couple le plus élevé soit transmis. Le montage de l'aimant permanent et de l'armature en fer peut bien entendu également avoir lieu de façon inverse, ce qui produit le même effet.
<EMI ID=4.1>
ment vertical magnétique ou électrique de préférence une pointe au lieu d'un
<EMI ID=5.1>
n'est plus nécessaire .En cas d'accouplement magnétique ou électrique horizontal, on peut employer un montage à pivot, sens devoir craindre des pertes par frottement dans la pratique. Dans ce cas il faut cependant préférer l'emploi de matériaux de palier non métallique. L'outil de coupe peut être relié indiffé-
<EMI ID=6.1>
rivé ou attaché de manière analogue, soit être fabriqué en une pièce avec l'organe entraîné.
L'outil de coupe a de préférence la forme d'une pièce estampée. Les aimants et les couteaux sont alors estampés ou transformés par injection de manière telle qu'il en résulte un organe lisse en forme de disque dont n'émergent que les éléments de coupe des couteaux. L'entrefer entre cet organe et la partie Inférieure du bol du mixer doit être maintenu aussi réduit que possible, pour que les restes d'aliments ne puissent se déposer dans la partie inférieure. Les avantages ainsi obtenus sont un couple élevé, l'absence presque totale d'espace mort et des possibilités de nettoyage aisées. Pour que la pièce estampée ne tombe pas lorsque le récipient est vidé, on prévoit un dispositif de sécurité.
Celui-ci est constitué par exemple pour un montage à pointe par un anneau élastique interposé et pour un montage à pivot par un couvercle de serrage passé sur le pivot qui émerge, ou analogue.
L'emploi de champs électriques offre encore des simplifications sup-

duit en court-circuit d'un moteur à induction. Le stator de ce moteur est en dehors du bol de travail et le rotor est monté dans ce dernier. L'emploi d'aimants permanents et d'armatures en fer n'est alors plus nécessaire et le rendement est augmenté.
Les avantages de l'invention résident dans une étanchéité impeccable de la chambre du moteur et dans la fabrication simple et peu coûteuse.
Le dessin représente quelques exemples réalisés suivant l'invention. La Fig. 1 représente une coupe à travers un mixer à accouplement vertical et
<EMI ID=8.1>
3 représente la liaison directe de l'outil de coupe avec un induit en court-circuit.
Dans la Fig. 1 l'aimant permanent 11 est solidaire de l'arbre 10
du moteur d'entraînement. Le bol du mixer 12 est monté sur le carter de mo-
<EMI ID=9.1>
lement par rapport au système d'entraînement. Grâce à la rainure annulaire
15 dans le fond du récipient du mixer 12, dans laquelle les pôles de l'aimant permanent 11 sont dirigés vers le haut, l'éloignement de l'armature en fer
16, revêtue de matière synthétique, est réduite; sans affaiblir le fond du
<EMI ID=10.1>
montée sur le pivot 18 aboutissant à une pointe de palier. L'anneau élastique
19 empêche la chute accidentelle de l'armature en fer 16 lorsque le récipient
12 est vidé, et permet d'autre part un démontage simple.
Les Figs. 2 et 3 représentent en principe la même construction et
les éléments semblables sont désignés par les mêmes chiffres. Dans la Fig. 2 l'aimant entraîné 20 a une forme en pot encore plus accentuée, et permet
pour cette raison un accouplement magnétique horizontal. L'organe entraîné
est 1 'aimant 21, sur lequel se trouve l'outil de coupe 17. Ici l'aimant 21
est monté sur le pivot 22. Le pivot de montage 22 ne sert ici toutefois presque exclusivement qu'au centrage et ne subit presque pas d'effort en direction verticale. Comme dispositif de sécurité on a prévu ici le couvercle élastique 23. Le récipient 12 du mixer est muni d'un bourrelet 24 et est posé
sur le carter 13 du moteur.
Sur le carter 25 du moteur de la Fig. 3 est posé par un bourrelet
le récipient de mixer 12. Sur le pivot de montage 22 se trouve l'induit en court-circuit 27, sur lequel se trouve l'outil de coupe 17. 28 désigne le
statcr du moteur à induction.
REVENDICATIONS.
1. Mixer, caractérisé en ce que la transmission de mouvement du moteur vers l'outil de coupe a lieu par des champs électriques et/ou magnétiques, le bol de travail étant séparé hermétiquement du carter du moteur.
<EMI ID=11.1>
The hermetic separation of the work bowl especially from the
<EMI ID = 1.1>
of building mixers. Special design measures are especially necessary at the point where the control shaft for the cutting tool enters the work bowl. The linings provided therein are generally not perfect and are subject to relatively high wear and rapid aging.
For this reason, the present invention provides for the transmission of energy from the motor to the cutting tool by electric and / or magnetic fields, the working bowl being hermetically separated from the motor housing.
When the energy transmission takes place by magnetic fields, a permanent magnet is preferably attached to the motor armature. On the extension of the motor shaft, in the work bowl, there is a pivot, on which there is an iron frame or also a permanent magnet,
<EMI ID = 2.1>
on the motor shaft performs a rotational movement "the permanent magnet, or the iron armature arranged in the working bowl follows this rotational movement. Depending on the type of mixer, the driven organ can � be placed above the.
<EMI ID = 3.1>
the air gap is as small as possible, so that the highest torque is transmitted. The mounting of the permanent magnet and the iron frame can of course also take place in reverse, which produces the same effect.
<EMI ID = 4.1>
vertical magnetic or electric preferably a point instead of a
<EMI ID = 5.1>
No longer necessary. In case of horizontal magnetic or electric coupling, a pivot assembly can be used, meaning that in practice frictional losses must be feared. In this case, however, the use of non-metallic bearing materials should be preferred. The cutting tool can be connected indifferently
<EMI ID = 6.1>
riveted or similarly attached, or be made in one piece with the driven member.
The cutting tool is preferably in the form of a stamped part. The magnets and the knives are then stamped or processed by injection in such a way that a smooth disc-shaped member results from which only the cutting elements of the knives emerge. The air gap between this part and the lower part of the mixer bowl must be kept as small as possible, so that food remains cannot settle in the lower part. The advantages thus obtained are a high torque, the almost total absence of dead space and easy cleaning possibilities. So that the stamped part does not fall when the container is emptied, a safety device is provided.
This is constituted, for example, for a point mounting by an interposed elastic ring and for a pivot mounting by a clamping cover passed over the emerging pivot, or the like.
The use of electric fields offers further simplifications.
<EMI ID = 7.1>
short-circuit of an induction motor. The stator of this motor is outside the work bowl and the rotor is mounted in the latter. The use of permanent magnets and iron frames is then no longer necessary and the efficiency is increased.
The advantages of the invention lie in impeccable sealing of the engine chamber and in the simple and inexpensive manufacture.
The drawing shows some examples produced according to the invention. Fig. 1 shows a section through a mixer with vertical coupling and
<EMI ID = 8.1>
3 shows the direct connection of the cutting tool with a short-circuited armature.
In Fig. 1 the permanent magnet 11 is integral with the shaft 10
drive motor. The mixer bowl 12 is mounted on the mo-
<EMI ID = 9.1>
in relation to the drive system. Thanks to the annular groove
15 in the bottom of the mixer container 12, in which the poles of the permanent magnet 11 point upwards, away from the iron frame
16, coated with synthetic material, is reduced; without weakening the background
<EMI ID = 10.1>
mounted on the pivot 18 leading to a bearing tip. The elastic ring
19 prevents accidental fall of the iron frame 16 when the container
12 is emptied, and on the other hand allows easy disassembly.
Figs. 2 and 3 represent in principle the same construction and
like elements are designated by the same numbers. In Fig. 2 The driven magnet 20 has an even more accentuated pot shape, and allows
for this reason a horizontal magnetic coupling. The trained organ
is the magnet 21, on which the cutting tool is located 17. Here the magnet 21
is mounted on the pivot 22. The mounting pivot 22 here however serves almost exclusively only for centering and hardly undergoes any force in the vertical direction. As a safety device there is provided here the elastic cover 23. The container 12 of the mixer is provided with a bead 24 and is placed
on the engine crankcase 13.
On the housing 25 of the engine of FIG. 3 is placed by a bead
the mixer container 12. On the mounting pivot 22 is the shorted armature 27, on which the cutting tool is located 17. 28 denotes the
statcr of the induction motor.
