La figure 6 est une vue en élévation de la paroi frontale ou face avant d'un four réalisé selon L'invention.Figure 6 is an elevational view of the front wall or front face of an oven produced according to the invention.
On se reporte auxdits dessins pour décrire un exemple avantageux, quoique nullement limitatif, de réalisation du four selon l'invention.Reference is made to said drawings to describe an advantageous, although in no way limiting, example of an embodiment of the oven according to the invention.
Ce four comporte un carter ou enveloppe 1 exécutée, de manière connue en soi, à l'aide de tôle d'acier, et dont Les parois sont, par exemple. constituées par deux plaques entre Lesquelles est disposée une matière isolante.This oven comprises a casing or casing 1 executed, in a manner known per se, using sheet steel, and the walls of which are, for example. constituted by two plates between which is arranged an insulating material.
A L'intérieur de cette enveloppe, est aménagée une chambre de cuisson 2 dans laquelle est monté le récipient ajouré ou panier tournant 3 destiné à contenir les produits à cuire ou à réchauffer. A l 'avant, Ladite enveloppe est équipée d'une porte 4 à double vitrage donnant accès à La chambre de cuisson et, plus précisément, au récipient tournant, en vue du remplissage de celui-ci.Inside this envelope, there is a cooking chamber 2 in which is mounted the perforated container or rotating basket 3 intended to contain the products to be cooked or reheated. At the front, said envelope is equipped with a door 4 with double glazing giving access to the cooking chamber and, more precisely, to the rotating container, with a view to filling it.
Le récipient ou panier tournant est constitué par un tambour comprenant, de manière également connue en soi, deux flasques circulaires d'extrémité 3a constituant Les bases opposées dudit tambour, ces flasques étant assemblées rigidement par une paroi Latérale ou paroi périphérique ajourée 3b de forme cyLindro-spi roîda Le dont L'un des bords 3c est placé en recouvrement de l'autre 3d, par exemple sur un arc d'environ 40 degrés ; lesdits bords étant, par ai lleurs, espacés L'un de l'-autre. De la sorte, une ouverture ou fente longitudinale 5 disposée horizontalement et dimensionnée pour permettre L 'introduction des aliments dans le tambour, se trouve ménagée entre lesdits bords superposés ; cette ouverture permettant également le déchargement ou déversement automatique dudit tambour. En effet, Lorsque le tambour tourne dans un sens (sens des aigui lles d'une montre selon La figure 3), Les aliments glissent sur la surface interne de la paroi cyli ndro-spi roîda Le 3b sans pouvoir sortir dudit tambour, tandis que Lorsque celui-ci tourne dans Le sens contraire (sens inverse des aiguiLles d'une montre suivant La figure 4), Les aliments sortent automatiquement par l'ouverture Longitudinale 5 Lorsque cette dernière a dépassé sa position La plus basse.The rotating container or basket consists of a drum comprising, in a manner also known per se, two circular end flanges 3a constituting the opposite bases of said drum, these flanges being rigidly assembled by a lateral wall or perforated peripheral wall 3b of cyLindro shape. -spi roîda Le of which One of the edges 3c is placed in overlap of the other 3d, for example on an arc of approximately 40 degrees; said edges being, by ai lleurs, spaced from each other. In this way, a longitudinal opening or slot 5 arranged horizontally and dimensioned to allow the introduction of food into the drum, is formed between said superimposed edges; this opening also allowing the automatic unloading or dumping of said drum. In fact, when the drum turns in one direction (the acute direction of a watch according to FIG. 3), the food slides on the internal surface of the wall cyli ndro-spi roîda Le 3b without being able to leave said drum, while When the latter turns in the opposite direction (opposite direction of the hands of a watch according to FIG. 4), the food comes out automatically through the longitudinal opening 5 when the latter has exceeded its lowest position.
La paroi ajourée 3b peut être constituée par une tôle perforée ou par une grille ou grillage.The perforated wall 3b can be constituted by a perforated sheet or by a grid or mesh.
Le tambour ajouré 3 est solidaire d'un arbre axial d'entraînement. Il est par exemple calé sur un arbre axial 6 monté tournant dans des paliers 13 disposés hors de La chambre de cuisson 2, cet arbre étant accouplé à un moteur inverseur 7 ou moto-réducteur à double sens de rotation. La mise en rotation (à La vitesse d'environ 1 tour/minute) de ce moteur inverseur 7 dans Le sens correspondant à la cuisson des aliments est commandée par une minuterie 8 par exemple installée sur la paroi frontale du four et permettant de programmer Le temps de cuisson (environ 8 minutes), tandis que L'inversion du sens de rotation dudit moteur inverseur et La mise en rotation dudit tambour dans le sens contraire permettant Le déchargement ou déversement des produits cuits peuvent être commandées par un bouton-poussoir 9 également installé sur ladite paroi frontale.The perforated drum 3 is integral with an axial drive shaft. It is for example wedged on an axial shaft 6 mounted rotating in bearings 13 arranged outside of the cooking chamber 2, this shaft being coupled to an inverter motor 7 or gear motor with two directions of rotation. The rotation (at a speed of about 1 revolution / minute) of this reversing motor 7 in the direction corresponding to the cooking of the food is controlled by a timer 8 for example installed on the front wall of the oven and making it possible to program the cooking time (about 8 minutes), while the inversion of the direction of rotation of said reversing motor and the rotation of said drum in the opposite direction allowing the unloading or spilling of cooked products can be controlled by a push button 9 also installed on said front wall.
Une came 10 est caLée sur L'arbre axial 6 d'entraînement du tambour 3. ou sur L'arbre de sortie du moteur inverseur ou moto-réducteur 7, accouplé audit arbre axial. L'élément actif "10a de cette came coopère avec un mîcrorupteur 11 ou appareil électrique analogue installé fixement à proximité de ladite came et dont l'organe de commande ou palpeur 11a est disposé sur La trajectoire dudit éLé ent actif. Le microrupteur 11 est placé sur le circuit électrique d'alimentation du moteur inverseur 7 et il est disposé de façon telle que son organe de commande ou palpeur 11a puisse être actionné par L'élément actif 10a de La came 10, lorsque Le moteur inverseur 7 tourne dans le sens du déchargement du tambour de cuisson, de manière à couper l'alimentation dudit moteur et à arrêter La rotation dudit tambour. D'autre part. L'ouverture 5 de chargement et de déversement du tambour et L'élément actif 10a de La came 10 sont positionnés réciproquement de manière telle que lorsque Ledit élément actif 10a actionne l'organe de commande 11a du microrupteur 11, Ladite ouverture 5 se trouve placée en regard de La porte 5 frontale 4 donnant accès à la chambre de cuisson 2 du four.A cam 10 is fitted to the axial shaft 6 for driving the drum 3. or to the output shaft of the reversing or gear motor 7, coupled to said axial shaft. The active element " 10a of this cam cooperates with a microswitch 11 or similar electrical device installed fixedly near said cam and whose control member or feeler 11a is disposed on the path of said active element. The microswitch 11 is placed on the electric supply circuit of the reversing motor 7 and it is arranged in such a way that its control member or probe 11a can be actuated by the active element 10a of the cam 10, when the reversing motor 7 rotates in the direction of unloading of the cooking drum, so as to cut off the supply to said motor and to stop rotation of said drum, on the other hand, the opening 5 for loading and discharging the drum and the active element 10a of the cam 10 are positioned reciprocally so that when said active element 10a actuates the control member 11a of the microswitch 11, said opening 5 is placed facing the front door 5 giving access to the cooking chamber 2 of the oven.
Au-dessous du tambour tournant, est placé un tiroir 12 muni d'une poignée frontale. Ce tiroir permet la récupération des frites cuites déchargées par le tambour, sans avoir à ouvrir La porte de chargement, ce qui Limite la déperdition de chaleur, lors de La récupération des produits cuits.Below the rotating drum is placed a drawer 12 provided with a front handle. This drawer allows the recovery of cooked fries discharged by the drum, without having to open the loading door, which limits heat loss, during the recovery of cooked products.
On ne décrit pas Les différents autres dispositifs ou agencements qui équipent Le four auquel 15 se rattache L'invention, ces dispositifs et agencements tels que : moyens de chauffage, dispositif de soufflage d'air chaud, agencement de la chambre de cuisson, dispositif d'extraction et d'élimination des fumées, etc., n'entrant pas dans le cadre du présent Brevet. _ On conçoit bien Le fonctionnement du four selon L ' i nvent i on.The various other devices or arrangements which equip the oven to which the invention relates are not described, these devices and arrangements such as: heating means, device for blowing hot air, arrangement of the cooking chamber, device for extraction and elimination of fumes, etc., which are outside the scope of this patent. _ We understand well The operation of the oven according to I nvent i on.
Lorsqu'on appuie sur le bouton de démarrage de la minuterie 8, après avoir garni le tambour de cuisson 3, on commande :When the timer 8 start button is pressed, after having fitted the cooking drum 3, the command is:
- la mise en route du moteur inverseur 7 et l'entraînement en rotation dudit tambour dans le sens de La cuisson (figure 3) ;- starting the reversing motor 7 and driving in rotation of said drum in the direction of cooking (Figure 3);
- La neutralisation du microrupteur 11.- Neutralization of the microswitch 11.
A la fin du temps de cuisson, l'arrêt de la , minuterie 8 coupe le circuit de cuisson et rétablit l 'ali entation du microrupteur 11, de sorte que la rotation du tambour de cuisson se trouve interrompue dès que L'élément actif 10a de La came 10 rencontre L 'organe de commande ou palpeur 11a du microrupteur 11. ,5 On appuie ensuite sur le bouton 9 qui commande l 'entraînement en rotation du moteur inverseur 7 en sens contraire et La mise en rotation du tambour dans Le sens inverse permettant Le déchargement automatique des produits dans Le tiroir 12 (figure 4).At the end of the cooking time, the stopping of the timer 8 cuts the cooking circuit and restores the supply of the microswitch 11, so that the rotation of the cooking drum is interrupted as soon as the active element 10a of the cam 10 meets the control member or feeler 11a of the microswitch 11., 5 Then press the button 9 which controls the rotation drive of the reversing motor 7 in opposite direction and the rotation of the drum in the opposite direction allowing the automatic unloading of the products in the drawer 12 (figure 4).
Cette rotation s'arrête dès que L'élément actif 10a de La came 10 rencontre et actionne l'organe de commande ou palpeur 11a du microrupteur 11. Lorsque la rotation du tambour 3 cesse. L'ouverture de chargement 5 de ce dernier se trouve disposée en regard de La porte 4, de sorte que Ledit tambour se trouve arrêté et parfaitement positionné pour un nouveau chargement (figure 2).This rotation stops as soon as the active element 10a of the cam 10 meets and actuates the control member or probe 11a of the microswitch 11. When the rotation of the drum 3 ceases. The loading opening 5 of the latter is located opposite door 4, so that said drum is stopped and perfectly positioned for a new loading (FIG. 2).
D'autres moyens pourraient être prévus pour assurer L'arrêt et Le positionnement automatiques du tambour de cuisson 3 à La fin de La phase de déversement des produits cuits.Other means could be provided to ensure the automatic stopping and positioning of the cooking drum 3 at the end of the pouring phase of the cooked products.
Par exemple, un aimant ou repère magnétique peut être fixé sur L'arbre d'entraînement 6 du tambour 3 et un capteur magnétique peut être disposé fixement à proximité de La portion de L'arbre équipé de cet aimant qui peut exciter ce capteur Lors de son passage devant ce dernier afin que Ledit capteur puisse émettre des signaux électriques en direction d'un contacteur ou autre appareil électrique assurant l'arrêt du moteur d'entraînement du tambour de cuisson. For example, a magnet or magnetic mark can be fixed on the drive shaft 6 of the drum 3 and a magnetic sensor can be fixedly fixed near the portion of the shaft equipped with this magnet which can excite this sensor during its passage in front of the latter so that said sensor can transmit electrical signals towards a contactor or other electrical device ensuring the stopping of the drive motor of the cooking drum.
