Description

La présente invention est relative aux fours pour la cuisson d'aliments.The present invention relates to ovens for cooking food.

Plus particulièrement, l'invention concerne un four pour la cuisson d'aliments comprenant :

  • une enceinte destinée à recevoir les aliments à chauffer et à contenir une atmosphère de cuisson, cette enceinte comportant deux parois horizontales, formant respectivement une sole et une voûte, reliées par au moins deux parois latérales verticales, cette enceinte étant fermée par au moins une porte également verticale,
  • un dispositif de chauffe disposé à l'intérieur de l'enceinte,
  • une turbine, également disposée à l'intérieur de l'enceinte, comportant au moins une pale tournant autour d'un espace central, sur une trajectoire circulaire centrée sur un axe de rotation, pour brasser l'atmosphère de cuisson chauffée par le dispositif de chauffe.
More particularly, the invention relates to an oven for cooking food comprising:
  • an enclosure intended to receive the food to be heated and to contain a cooking atmosphere, this enclosure comprising two horizontal walls, forming respectively a floor and a roof, connected by at least two vertical side walls, this enclosure being closed by at least one door also vertical,
  • a heating device disposed inside the enclosure,
  • a turbine, also disposed within the enclosure, comprising at least one blade rotating about a central space, on a circular path centered on an axis of rotation, for stirring the heated cooking atmosphere by the device of heated.

On connaît déjà des fours de ce type, notamment par EP-A-0733862 , dans lesquels, par exemple, les aliments à cuire sont répartis sur des plateaux disposés sur plusieurs niveaux Dans ces fours, les aliments doivent cuire à la même vitesse et avec le même degré de cuisson à tous les niveaux. L'homogénéité de la distribution de la chaleur dans ces fours est donc particulièrement importante.Furnaces of this type are already known, in particular by EP-A-0733862 , in which, for example, the foods to be cooked are distributed on trays arranged on several levels In these ovens, the food must cook at the same speed and with the same degree of cooking at all levels. The homogeneity of the distribution of heat in these furnaces is therefore particularly important.

La présente invention a notamment pour but d'améliorer l'homogénéité de la distribution de la chaleur dans l'enceinte des fours de ce type.The present invention is intended in particular to improve the homogeneity of the distribution of heat in the enclosure of the furnaces of this type.

A cet effet, on prévoit selon l'invention, un four pour la cuisson d'aliments selon la revendication 1.For this purpose, according to the invention, an oven for cooking food according to claim 1.

Grâce à ces dispositions, la chaleur produite par le dispositif de chauffe est aspirée par la turbine puis distribuée, autour de celle-ci, de façon homogène. Ceci contribue à améliorer considérablement la distribution de la chaleur dans la totalité du volume de l'enceinte. Au-delà, on profite de la température relativement basse régnant dans le conduit d'alimentation, grâce à son balayage par le gaz de combustion, pour y protéger les fils d'alimentation électrique.Thanks to these provisions, the heat produced by the heating device is sucked by the turbine and then distributed around it, homogeneously. This helps to significantly improve the distribution of heat in the entire volume of the enclosure. Beyond that, we take advantage of the relatively low temperature prevailing in the supply duct, thanks to its scavenging by the combustion gas, to protect the power supply son.

Dans des modes de réalisation préférés de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • l'axe de rotation est horizontal ; ainsi, par exemple, la turbine est montée rotative sur l'une des parois verticales de l'enceinte ;
  • les orifices de la plaque du brûleur sont adaptés pour que les flammes générées par la combustion du gaz combustible soient réparties sur 360° par rapport à l'axe de rotation ;
  • la plaque est munie d'une électrode d'allumage et d'un dispositif de contrôle de flamme, par exemple par ionisation ; et
  • il comporte une grille de protection munie d'un cadre délimitant une ouverture dont la surface est supérieure ou sensiblement égale à celle de la turbine considérée perpendiculairement à l'axe de rotation.
In preferred embodiments of the invention, one or more of the following may also be used:
  • the axis of rotation is horizontal; thus, for example, the turbine is rotatably mounted on one of the vertical walls of the enclosure;
  • the orifices of the burner plate are adapted so that the flames generated by the combustion of the combustible gas are distributed over 360 ° with respect to the axis of rotation;
  • the plate is provided with an ignition electrode and a flame control device, for example by ionization; and
  • it comprises a protective grid provided with a frame delimiting an opening whose surface is greater or substantially equal to that of the turbine considered perpendicular to the axis of rotation.

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.
Un exemple de mode de réalisation du four selon l'invention est décrit ci-dessous en relation avec les figures 1 à 4.In the different figures, the same references designate identical or similar elements.
An exemplary embodiment of the oven according to the invention is described below in connection with FIGS. 1 to 4.

Comme représenté sur la figure 1, le four 1 selon l'invention comprend une enceinte 2 (ou moufle) contenue dans un coffrage 3. Ce coffrage 3 comporte des moyens de régulation de la température 4 dans l'enceinte 2, ainsi qu'une porte 5 destinée à l'introduction dans l'enceinte 2.As represented in FIG. 1, the oven 1 according to the invention comprises an enclosure 2 (or muffle) contained in a formwork 3. This formwork 3 comprises means for regulating the temperature 4 in the enclosure 2, as well as a door 5 intended for introduction into the enclosure 2.

L'enceinte 2 a une forme sensiblement parallélépipédique avec une face avant 6, ouverte ou fermée par la porte 5, une paroi de fond 7 opposée à la face avant 6, deux parois latérales 8 verticales, entre la face avant 6 et la paroi de fond 7, ainsi qu'une sole 9 et une voûte 10 formant deux parois horizontales.The enclosure 2 has a substantially parallelepipedal shape with a front face 6, open or closed by the door 5, a bottom wall 7 opposite the front face 6, two vertical side walls 8, between the front face 6 and the wall of the housing. bottom 7, and a sole 9 and a vault 10 forming two horizontal walls.

Comme représenté sur la figure 2, le four 1 selon l'invention comporte également un dispositif de chauffe 11, une turbine 12, une grille de protection 13 et des glissières 14. La turbine 12 est montée sur la paroi de fond 7.As shown in FIG. 2, the oven 1 according to the invention also comprises a heating device 11, a turbine 12, a protective grid 13 and slides 14. The turbine 12 is mounted on the bottom wall 7.

Le dispositif de chauffe 11 est disposé à l'intérieur de l'enceinte 2, en regard de la turbine 12. Avantageusement, il s'agit d'un brûleur à gaz de combustion. Il est alimenté en gaz de combustion par un conduit 15. Ce brûleur est allumé par une électrode 16 alimentée électriquement par un fil 17 arrivant dans le brûleur par le conduit 15. Ce brûleur sera décrit de manière plus détaillée ci-dessous en relation avec les figures 3 et 4.The heating device 11 is disposed inside the chamber 2, facing the turbine 12. Advantageously, it is a combustion gas burner. It is fed with combustion gas via a conduit 15. This burner is ignited by an electrode 16 electrically powered by a wire 17 arriving in the burner via the conduit 15. This burner will be described in more detail below in relation to the Figures 3 and 4.

Ce brûleur comporte avantageusement un dispositif de contrôle de flamme 16a, par exemple par ionisation, raccordé à un boîtier de contrôle (non représenté) par un fil 17a.This burner advantageously comprises a flame control device 16a, for example by ionization, connected to a control box (not shown) by a wire 17a.

Le gaz de combustion est avantageusement un mélange air/gaz arrivant au niveau du brûleur en légère surpression.The combustion gas is advantageously an air / gas mixture arriving at the burner at a slight overpressure.

La turbine 12 est constituée d'un disque 18 centré sur un axe de rotation 19. En périphérie de ce disque 18, la turbine 12 comporte une pluralité de pales 20 régulièrement angulairement réparties autour de l'axe de rotation 19. Ces pales 20 sont par exemple constituées de lamelles rectangulaires planes s'étendant dans un plan sensiblement perpendiculaire au disque 18 et passant par l'axe de rotation 19. Lors de leur rotation, elles parcourent une trajectoire circulaire centrée sur l'axe de rotation 19 et délimitent un espace central 21. La turbine 12 est entraînée en rotation, autour de l'axe de rotation 19, par un moteur 22, par exemple électrique. Elle permet de répartir l'énergie calorifique dans l'enceinte 2.The turbine 12 consists of a disc 18 centered on an axis of rotation 19. At the periphery of this disc 18, the turbine 12 comprises a plurality of blades 20 regularly angularly distributed around the axis of rotation 19. These blades 20 consist for example of flat rectangular lamellae extending in a plane substantially perpendicular to the disk 18 and passing through the axis of rotation 19. During their rotation, they travel in a circular path centered on the axis of rotation 19 and define a central space 21. The turbine 12 is rotated about the axis of rotation 19 by a motor 22, by electric example. It makes it possible to distribute the heat energy in the enclosure 2.

La grille de protection 13 s'étend dans un plan vertical en regard du disque 18, devant le brûleur 11 et la turbine 12, relativement à l'espace 23 destiné à recevoir les aliments à chauffer et situé entre ce brûleur 11 et la porte 5.The protective grid 13 extends in a vertical plane facing the disc 18, in front of the burner 11 and the turbine 12, relative to the space 23 intended to receive the food to be heated and situated between this burner 11 and the door 5 .

Les glissières 14, au nombre de dix paires, sont disposées sensiblement horizontalement sur les parois latérales 8. Chaque paroi latérale 8 comporte une glissière 14 de chaque paire. Ces glissières 14 permettent de maintenir des plateaux sur lesquels sont disposés les aliments à chauffer et/ou à cuire.The slides 14, in number of ten pairs, are disposed substantially horizontally on the side walls 8. Each side wall 8 comprises a slide 14 of each pair. These slides 14 make it possible to maintain trays on which are placed the food to be heated and / or cooked.

Le brûleur 11 est disposé en regard de l'espace central 21. Avantageusement, une partie de ce brûleur 11 pénètre dans cet espace central 21. L'enceinte 2 comporte un orifice d'évacuation 31 des gaz contenu dans l'enceinte 2.The burner 11 is arranged facing the central space 21. Advantageously, a part of this burner 11 enters this central space 21. The chamber 2 comprises a discharge orifice 31 of the gas contained in the chamber 2.

Comme représenté sur la figure 3, le brûleur 11 comporte une cuvette 24 et une plaque 25. Avantageusement, cette cuvette 24 et cette plaque 25 sont en laiton.As shown in Figure 3, the burner 11 has a bowl 24 and a plate 25. Advantageously, this bowl 24 and this plate 25 are made of brass.

La cuvette 24 est raccordée au conduit 15 d'alimentation et est obturée par la plaque 25, du côté du brûleur 11 orienté vers la paroi de fond 7 de l'enceinte 2.The bowl 24 is connected to the supply duct 15 and is closed by the plate 25, on the burner side 11 facing the bottom wall 7 of the enclosure 2.

Comme représenté sur la figure 4, la plaque 25 se présente sous la forme d'un anneau avec une ouverture centrale 26 qui se prolonge, perpendiculairement à la plaque 25, jusqu'au fond de la cuvette 24 par un tube 27. La plaque 25 fait sensiblement 15 mm d'épaisseur. La zone de cet anneau située entre l'ouverture centrale 26 et sa périphérie est percée d'orifices 28 régulièrement répartis sur huit cercles concentriques A-H. Ces cercles concentriques ont respectivement 66 mm, 74 mm, 82 mm, 90 mm, 98 mm, 106 mm, 114 mm et 122 mm de diamètre. On trouve sur ces cercles respectivement 32, 32, 40, 48, 48, 64, 64 et 64 orifices 28. Chaque orifice 28 a un diamètre sensiblement égal à 2,4 mm.As shown in FIG. 4, the plate 25 present in the form of a ring with a central opening 26 which extends perpendicular to the plate 25, to the bottom of the bowl 24 by a tube 27. The plate 25 is substantially 15 mm thick. The zone of this ring situated between the central opening 26 and its periphery is pierced with orifices 28 regularly distributed over eight concentric circles AH. These concentric circles are respectively 66 mm, 74 mm, 82 mm, 90 mm, 98 mm, 106 mm, 114 mm and 122 mm in diameter. On these circles, respectively, are 32, 32, 40, 48, 48, 64, 64 and 64 orifices 28. Each orifice 28 has a diameter substantially equal to 2.4 mm.

La plaque 25 comporte un renfoncement 29 ayant une profondeur sensiblement égale la 3 mm. Ainsi.les orifices 28 n'affleurent pas directement à la surface de la plaque 25 et se trouvent en partie protégés des turbulences générées par la turbine 12. La géométrie des orifices 28 et du renfoncement 29 est adaptée pour que les flammes générées par la combustion du gaz s'étendent, sous l'effet de la turbine 12, radialement par rapport à l'ouverture centrale 26, sur 360°.The plate 25 has a recess 29 having a depth substantially equal to 3 mm. Thus, the orifices 28 do not directly abut the surface of the plate 25 and are partly protected from turbulence generated by the turbine 12. The geometry of the orifices 28 and the recess 29 is adapted so that the flames generated by the combustion gas extend, under the effect of the turbine 12, radially relative to the central opening 26, over 360 °.

La plaque 25 comporte en outre deux passages 30 pour l'électrode 16 d'allumage et le dispositif de contrôle de la flamme 16a.The plate 25 further comprises two passages 30 for the ignition electrode 16 and the flame control device 16a.

Le four selon l'invention peut faire l'objet de nombreuses variantes sans sortir du cadre de l'invention.The oven according to the invention can be subject to many variations without departing from the scope of the invention.

Ainsi, selon une variante non représentée, l'enceinte 2 comporte une face avant et une face arrière, ouvertes ou fermées, chacune par une porte. Dans ce cas, une turbine 12 est montée, par exemple, sur au moins une paroi latérale 8 et le dispositif de chauffe 11 est placé en regard de chaque turbine 12.Thus, according to a variant not shown, the chamber 2 comprises a front face and a rear face, open or closed, each by a door. In this case, a turbine 12 is mounted, for example, on at least one side wall 8 and the heating device 11 is placed opposite each turbine 12.

Selon d'autres variantes, plusieurs turbines et plusieurs brûleurs sont disposés sur une même paroi.According to other variants, several turbines and several burners are arranged on the same wall.

Selon encore d'autres variantes, le four selon l'invention comporte une grille de protection 13 telle que représentée sur les figures 5 et 6. Cette grille de protection 13 n'est pas limitée, contrairement à ce qui a été décrit ci-dessus, à une surface correspondant à celle en regard de la turbine 12. La grille de protection 13 est supportée par un cadre 40 métallique. Ce cadre 40 s'étend sur la majeure partie de l'ouverture de la cavité interne de l'enceinte 2, dans un plan parallèle à la paroi de fond 7. Les dimensions du cadre 40 sont sensiblement égales ou supérieures à celles de la turbine 12. Ainsi, l'atmosphère de cuisson circule dans l'enceinte 2 en étant aspirée vers le centre de la turbine 12, à l'intérieur du cadre 40, puis soufflée en périphérie de la turbine 12 à l'extérieur du cadre 41. Le cadre 41 peut jouer un rôle déflecteur. Le cadre 40 est, par exemple, maintenu dans l'enceinte 2, grâce à des pattes 41, sur la sole 9 et la voûte 10. Selon certaines variantes, la grille de protection 13 et le cadre 40 sont aisément démontables pour être nettoyés indépendamment du four 1.According to still other variants, the oven according to the invention comprises a protective grid 13 as shown in FIGS. 5 and 6. This protection grid 13 is not limited, contrary to what has been described above. , at a surface corresponding to that facing the turbine 12. The protective grid 13 is supported by a frame 40 metal. This frame 40 extends over most of the opening of the internal cavity of the chamber 2, in a plane parallel to the bottom wall 7. The dimensions of the frame 40 are substantially equal to or greater than those of the turbine 12. Thus, the baking atmosphere circulates in the chamber 2 while being sucked towards the center of the turbine 12, inside the frame 40, and then blown at the periphery of the turbine 12 outside the frame 41. The frame 41 can play a deflector role. The frame 40 is, for example, held in the chamber 2, by means of lugs 41, on the hearth 9 and the vault 10. According to some variants, the protective grid 13 and the frame 40 are easily dismountable to be cleaned independently oven 1.
