Abstract

The coffee mill has a hopper or funnel (11) into which the coffee beans are placed. It stands on top of a casing (10) which contains the coffee grinder element (12); this consists of a moving element acting against a stationary element. The coffee powder escapes sideways from the mill into a chute or opening (13) which is closed by a flap valve (21). The flap valve is hinged at the top (20). Normally it hangs vertically, closing the opening (13), but it can swing upwards to let the coffee powder escape. There is a plastics frame piece (16) set at an angle in front of the flap valve, which has an aperture through which the flap valve can swing. The coffee powder falls down from the flap valve into a container (14).

Description

" Moulin à café pourvu d'un déflecteur basculant apte à
canaliser la poudre de café vers l'intérieur d'un réclN
pient collecteur"
L'invention concerne un moulin à café pourvu d'un déflecteur basculant apte à canaliser la poudre de café vers l'intérieur d'un récipient collecteur.
"Coffee grinder provided with a tilting deflector suitable for
channel the coffee powder inside a container
pient collector "
The invention relates to a coffee grinder provided with a tilting deflector capable of channeling the coffee powder towards the interior of a collecting container.

Dans les moulins à café, la poudre obtenue par le broyage des grains est chassée radialement des meuve les dentées dans un récipient amovible ou fixe, en passant par un orifice de sortie qui relie la chambre de mouture à ce récipient. In coffee grinders, the powder obtained by grinding the beans is expelled radially from the teeth in a removable or fixed container, passing through an outlet opening which connects the grinding chamber to this container.

Suivant la technique, il est connu de dis- poser, à proximité de cet orifice, à l'intérieur du récipient, un déflecteur fixe destiné à rabattre la poudre de café sortant vers le bas afin qu'elle ne parvienne pas contre le couvercle du récipient par où elle pourrait swéchapX per. According to the technique, it is known to have, near this orifice, inside the container, a fixed deflector intended to fold the coffee powder exiting downwards so that it does not reach the lid of the container where she could swechapX per.

La violence et la grande vitesse avec lesquelles la poudre de café est expulsée, et la charge de courant électrostatique acquise pendant la mouture, font qu'elle s'amasse et s'accumule à à proximité de l'orifice de sortie. The violence and the high speed with which the coffee powder is expelled, and the charge of electrostatic current acquired during the grinding, causes it to collect and accumulate near the exit orifice.

Si la poudre reste dans cette zone, cela risque de provoquer l'obstruction de l'orifice de sortie du groupe broyeur avec le risque grave qui s'en suit de blocage de ce groupe lui-m8me avec des conséquences néfastes pour le moteur qui, bien que surdimensionné, est également sujet à se rompre facilement. If the powder remains in this zone, this risks causing the blocking of the outlet opening of the grinding group with the serious risk which follows of blocking this group itself with harmful consequences for the engine which, although oversized, is also prone to break easily.

La présente invention a pour but d'éliminer ce risque d'endommager le groupe moteur en empêchant que la poudre de café à sa sortie du groupe broyeur soit projetée directivement dans le conteneur ou contre son couvercle, d'où elle pourrait s'échapper à l'extérieur. The object of the present invention is to eliminate this risk of damaging the motor unit by preventing the coffee powder on leaving the grinder group from being sprayed directly into the container or against its lid, from which it could escape. outside.

Dans ce but, l'invention a pour objet un moulin à café avec un déflecteur apte à diriger la poudre de café expulsée radialement du groupe broyeur en passant par un orifice, dans un récipient inférieur, moulin caractérisé en ce que le déflecteur est constitué essentiellement par une ailette déflectrice, pouvant basculer sur un petit arbre et placée en correspondance avec l'orifice de sortie de la poudre hors de ce groupe broyeur. To this end, the subject of the invention is a coffee grinder with a deflector capable of directing the coffee powder expelled radially from the grinder group by passing through an orifice, in a lower container, mill characterized in that the deflector consists essentially by a deflecting fin, capable of tilting on a small shaft and placed in correspondence with the powder outlet orifice outside this grinding group.

Les caractéristiques fonctionnelles et structurelles, ainsi que les avantages d'un déflecteur réalisé conformément à l'invention, apparaitront plus clairement d'après la description ci-après d'un exemple possible de réalisation, non limitatif, de l'invention, avec référence aux dessins annexés, dans lesquels :
- la figure 1 est une vue schématique en élévation partiellement en coupe d'un moulin à café pourvu d'un déflecteur conforme à l'inventìon,
- la figure 2 est une vue en élévation d'un déflecteur conforme à l'invention suivant la ligne Il-Il de la figure 3.
The functional and structural characteristics, as well as the advantages of a deflector produced in accordance with the invention, will appear more clearly from the description below of a possible non-limiting example of embodiment of the invention, with reference to the accompanying drawings, in which:
FIG. 1 is a schematic elevational view partially in section of a coffee grinder provided with a deflector according to the invention,
FIG. 2 is an elevation view of a deflector according to the invention along the line Il-Il of FIG. 3.

- la figure 3 est une vue frontale du déflee- teur, partiellement en coupe, suivant la flèche X de la figure 2.  FIG. 3 is a front view of the deflector, partially in section, along arrow X in FIG. 2.

Si l'on se réfère aux dessins, dans un moulin à afé, désigné dans son ensemble par 10, le café en grains, placé dans une trémie d'alimentation 11, arrive dans un groupe de broyage et de mouture 12 qui le chasse, sous forme de poudre, par l'orifice 13, l'envoyant dans un récipient qui peut 8trie ou fixe, ou facile à enlever. If we refer to the drawings, in an afé mill, designated as a whole by 10, the coffee beans, placed in a feed hopper 11, arrives in a grinding and grinding group 12 which drives it out, in powder form, through orifice 13, sending it into a container which can be 8trie or fixed, or easy to remove.

Un déflecteur basculant, désigné dans son ensemble par la référence 15 et placé à la sortie de l'orifice 13, est constitué par un corps 16 en matière plastique moulée en forme de U, inclinée par rapport à deux supports latéraux 17 qui présentent chacun un perçage fileté 18 pour leur fixation au moulin 10, ainsi qu'un - perçage supérieur 19 perpendiculaire au premier perçage 18. A tilting deflector, designated as a whole by the reference 15 and placed at the outlet of the orifice 13, is constituted by a body 16 of plastic material molded in a U shape, inclined with respect to two lateral supports 17 which each have a threaded bore 18 for fixing them to the mill 10, as well as an upper bore 19 perpendicular to the first bore 18.

Les perçages 19 reçoivent à rotation libre un petit arbre 20 sur lequel est fixée, en 22, une ailette déflectrice 21 qui peut ainsi osciller à l'intérieur du corps de support 16. The holes 19 receive free rotation a small shaft 20 on which is fixed, at 22, a deflecting fin 21 which can thus oscillate inside the support body 16.

Le mode de fonctionnement du déflecteur basculant conforme à l'invention est le suivant :
Le café en grains placé dans la trémie d'al- mentation Il du moulin à café 10, est amené de manière continue au groupe de mouture 12 qui est destiné à le ré- duire en poudre.
The operating mode of the tilting deflector according to the invention is as follows:
The coffee beans placed in the feed hopper II of the coffee grinder 10 is continuously fed to the grinding group 12 which is intended to reduce it to powder.

Le groupe broyeur 12, qui tourne à grande vitesse, chasse la poudre de café par l'orifice 13, vers le conteneur 14. Cette poudre rencontre l'ailette 21, placée comme le montre la figure 1. Elle la fait alors basculer, dans les positions représentées en traits-points sur le petit axe 20. The grinding group 12, which rotates at high speed, drives the coffee powder through the orifice 13, towards the container 14. This powder meets the fin 21, placed as shown in FIG. 1. It then causes it to tip, into the positions represented by line-dots on the minor axis 20.

Un tel mouvement oscillant de l'ailette seop- pose à ce que la poudre de café s'accumule devant l'orifice 13 et sur l'ailette 21, la faisant tomber dans le récipient 14. Such an oscillating movement of the fin means that the coffee powder accumulates in front of the orifice 13 and on the fin 21, causing it to fall into the container 14.

Cé déflecteur basculant 15 a pour effet qu'il ne se forme pas de dépits de poudre de café, que l'orifice 13 ne se bouche pas, et que, en conséquence, la groupe moteur (non représenté) du moulin à café ne risque pas de se détériorer. This tilting deflector 15 has the effect that it does not form coffee powder deposits, that the orifice 13 does not become clogged, and that, consequently, the motor unit (not shown) of the coffee grinder does not risk not to deteriorate.

il est en outre toujours assuré que la poudre de café ne s'échappera pas par la partie supérieure du récipient 14. it is furthermore always ensured that the coffee powder will not escape through the upper part of the container 14.

La prévision dtun tel déflecteur basculant permet de doter le moulin à café de moteurs électriques d'une puissance moindre que ceux qu'on utilise habituellement et relativement économiques.  The provision of such a tilting deflector makes it possible to provide the coffee grinder with electric motors of less power than those which are usually used and relatively economical.
