Abstract

The device operates within a vertical channel (7) on the rim of the bin (3) which is fitted removably to a base (1). A rotary cutter projects upward from the base into the bin and is driven by an electric motor under the control of a switch (11). The switch is operated by a permanent magnet (12) on the lower end of a spring-loaded plunger (8) only when the bin and its lid (10) are secured in position and the cutter is inaccessible.. The appts. is more childproof than prior-art devices with electromechanical switches, and the spring-loaded mechanism is shielded from dust.

Description

La présente in ention a pour objet un dispositif de sécurité destiné en particulier mais non exclusivement à un robot de cuisine du type comportant dans une cuve amovible un outil entraîné en rotation par un moteur électrique, monté lui-même dans un socle. The present in ention relates to a safety device intended in particular but not exclusively for a food processor of the type comprising in a removable tank a tool driven in rotation by an electric motor, itself mounted in a base.

I1 existe déjà des robots de cuisine ou "food processors" équipés d'un dispositif de sécurité qui ne permettent l'entrainement en rotation de l'outil que lorsque la cuve de l'appareil est montée sur son socle et fermée convenablement par son couvercle amovible. I1 already exist kitchen robots or "food processors" equipped with a safety device which only allow the tool to rotate in rotation when the tank of the appliance is mounted on its base and properly closed by its cover. removable.

Le but d'un tel dispositif est d'éviter tout contact entre les mains de l'utilisateur et l'outil généralement coupant lorsqu'il tourne à grande vitesse. The purpose of such a device is to avoid contact between the hands of the user and the generally cutting tool when it rotates at high speed.

Les dispositifs connus comportent géneralement un contact de travail inséré dans le circuit d'alimentation du moteur électrique et monté dans une position appropriée pour être actionné mécaniquement par une partie de la cuve lorsqu'elle est montée sur son socle. De tels dispositifs de securité à commande mécanique ne sont pas entièrement fiables, puisque, par exemple un enfant peut actionner le contact de travail et déclencher par suite la rotation de l'appareil en introduisant un objet pointu quelconque dans l'orifice du socle prévu pour la commande mécanique du contact de travail puisque cet orifice est dégagé lorsque la cuve nez ne se trouve pas dans sa position correcte sur le socle de l'appareil. Known devices generally comprise a working contact inserted in the supply circuit of the electric motor and mounted in a position suitable for being actuated mechanically by a part of the tank when it is mounted on its base. Such mechanical safety devices are not entirely reliable, since, for example, a child can actuate the working contact and consequently trigger the rotation of the device by introducing any sharp object into the orifice of the base provided for the mechanical control of the working contact since this orifice is cleared when the nose bowl is not in its correct position on the base of the device.

Un dispositif de ce genre est décrit dans le brevet français nO 71 27039 au nom de Pierre Verdun. Dans ce brevet, une tige poussoir s'étend sur toute la hauteur de la cuve dans un canal à l'intérieur duquel elle est montée coulissante de manière à ce qu'une came portée par le couvercle vienne appuyer sur ladite tige poussoir pour la faire pénétrer dans le socle ou elle vient porter sur un contacteur de sécurité. A device of this kind is described in French patent no. 71 27039 in the name of Pierre Verdun. In this patent, a push rod extends over the entire height of the tank in a channel inside which it is slidably mounted so that a cam carried by the cover comes to press on said push rod to make it enter the base or it comes to bear on a safety switch.

Dans certains cas, le nettoyage du canal à l'intérieur duquel se déplace la tige poussoir peut présenter des difficultés. In some cases, cleaning the channel inside which the push rod moves can present difficulties.

La présente invention a pour objet de remédier à cet inconvénient. Selon la présente invention, le dispositif de sécurité pour robot de cuisine comportant une cuve amovible fermée par un couvercle salement amovible, un outil entraîné en rotation par un moteur electrique monté lui-même dans un socle et dont l'axe fait saillie à l'intérieur de ladite cuve, est caractérisé en ce que ledit couvercle porte un aimant qui, lorsque le couvercle est convenablement assujetti sur la cuve, vient en face d'une tige de matériau ferro-magnétique qui, lorsque la cuve est convenablement assujettie sur le socle, est disposée en regard d'un interrupteur magnétique. The object of the present invention is to remedy this drawback. According to the present invention, the safety device for food processor comprising a removable tank closed by a dirty removable cover, a tool driven in rotation by an electric motor mounted itself in a base and whose axis projects inside of said tank, is characterized in that said cover carries a magnet which, when the cover is suitably fixed on the tank, comes opposite a rod of ferro-magnetic material which, when the tank is suitably fixed on the base , is arranged next to a magnetic switch.

Ainsi, le canal renfermant la tige de matériau ferro-magnétique tel que du fer doux ou une ferrite par exemple peut être hermétiquement clos, ce qui facilite les problèmes de nettoyage. D'autre part, il n'existe sur le socle aucun orifice apparent qui soit de nature à inciter à une mise en route interdite. Thus, the channel containing the rod of ferro-magnetic material such as soft iron or a ferrite for example can be hermetically sealed, which facilitates cleaning problems. On the other hand, there is no apparent opening on the base which is likely to encourage a prohibited start-up.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre d'un mode particulier de réalisation donné à titre d'exemple non limitatif, en regard de la figure unique qui représente la coupe d'un appareil selon l'invention. Other characteristics and advantages of the invention will appear during the following description of a particular embodiment given by way of nonlimiting example, with reference to the single figure which represents the section of an apparatus according to the invention.

Sur la figure unique, le socle creux 1, par exemple en matière synthétique moulée, renferme un moteur électrique 2 monté de manière à ce que son axe soit vertical et traverse la paroi supérieure la du socle. La cuve amovible 3 de forme cylindrique permet le passage à travers son fond 3a de l'arbre du moteur 2. In the single figure, the hollow base 1, for example of molded synthetic material, contains an electric motor 2 mounted so that its axis is vertical and passes through the upper wall 1a of the base. The removable tank 3 of cylindrical shape allows the motor shaft 2 to pass through its bottom 3a.

Un outil 4 comportant par exemple des couteaux radiaux 4a peut être accouplé par tout moyen approprié sur l'extrémité de l'arbre à l'intérieur de la cuve 3 montée sur le socle 1. A tool 4 comprising for example radial knives 4a can be coupled by any suitable means on the end of the shaft inside the tank 3 mounted on the base 1.

Cet appareil comprend un dispositif de sécurité composé d'un contact de travail 5 constitué par exemple par un interrupteur magnétique de type I.L.S. fixé à l'intérieur du socle 1 de l'appareil et lorsque la cuve 3 est montée de façon correcte sur le socle 1, une tige 6 de matériau ferro-magnetique tel que du fer doux ou de la ferrite par exemple est placée en regard de l'interrupteur 5. Cette tige 6 est noyée à l'intérieur d'un canal 7 moulé avec la cuve. Le couvercle 10 qui est monté sur la cuve 3 par l'intermédiaire de taquets 12 porte un aimant 8 qui, lorsque le couvercle est convenablement verrouilé, arrive au regard de la tige 6.This device comprises a safety device composed of a working contact 5 constituted for example by a magnetic switch of type I.L.S. fixed inside the base 1 of the device and when the tank 3 is correctly mounted on the base 1, a rod 6 of ferro-magnetic material such as soft iron or ferrite for example is placed opposite of the switch 5. This rod 6 is embedded inside a channel 7 molded with the tank. The cover 10 which is mounted on the tank 3 by means of tabs 12 carries a magnet 8 which, when the cover is properly locked, comes into view of the rod 6.

A la partie supérieure du couvercle 10 est prévue une goulotte 9 permettant l'introduction des produits à traiter, le couvercle présentant par ailleurs une jupe de guidage 11 pénétrant à l'intérieur de la cuve 3, L'aimant 8 est d'une hau-teur sensiblement egale à celle de la jupe 11 de sorte que l'espace 13 existant entre le bas de l'aimant 8 et la partie supérieure de la tige 6 soit aussi réduit que possible et même pratiquement nul de sorte que l'aimant soit en contact direct avec la tige de fer doux. Le fonctionnement du dispositif est extrêmement simple. Lorsque la cuve 3 est convenablement montée sur le socle 1, la partie inférieure de la tige 6 arrive au regard et à proximité de l'interrupteur 5. Puis, lorsque le couvercle 10 est monté sur la cuve 3 dans sa position de verrouillage, l'aimant 8 polarise la tige 6 qui agit sur l'interrupteur 5, ce qui permet la mise en route du moteur, soit directement, soit par l'intermédiaire d'un interrupteur de commande supplémentaire. At the upper part of the cover 10 is provided a chute 9 allowing the introduction of the products to be treated, the cover also having a guide skirt 11 penetrating inside the tank 3, The magnet 8 is of a height -tor substantially equal to that of the skirt 11 so that the space 13 existing between the bottom of the magnet 8 and the upper part of the rod 6 is as small as possible and even practically zero so that the magnet is in direct contact with the soft iron rod. The operation of the device is extremely simple. When the tank 3 is suitably mounted on the base 1, the lower part of the rod 6 comes into view and close to the switch 5. Then, when the cover 10 is mounted on the tank 3 in its locking position, the magnet 8 polarizes the rod 6 which acts on the switch 5, which allows the engine to be started, either directly or via an additional control switch.

Il va de soi que des modifications peuvent être apportées au mode de réalisation qui vient d'être décrit, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de la présente invention. It goes without saying that modifications can be made to the embodiment which has just been described, in particular by substitution of equivalent technical means, without departing from the scope of the present invention.
