Description

La présente invention concerne un four à chauffage électrique destiné notamment aux opérations de cuisson industrielle, principalement pour la boulangerie.The present invention relates to an electric heating oven intended in particular industrial cooking operations, mainly for baking.

Il existe deux catégories de fours , à savoir les fours à chauffage statique et les fours à circulation forcée. Dans un four à chauffage statique , une première batterie de résistances électriques est disposée au niveau du plafond de l'enceinte tandis qu'une seconde batterie de résistances électriques est disposée à proximité et en-dessous d'une dalle réfractaire sur laquelle sont placés les produits à cuire, dalle dénommée également sole réfractaire. Les résistances électriques de la seconde batterie ont pour fonction de chauffer la dalle réfractaire. Dans le cas d'un four de boulangerie, on obtient en fin de cuisson un aspect qui n'est pas homogène sur toute la périphérie extérieure du produit , notamment du pain, la partie en contact avec la dalle réfractaire ayant superficiellement une cuisson plus accentuée . L'utilisation de cette première catégorie de four à chauffage statique et à sole réfractaire est donc préconisée lorsque l'on cherche à donner au produit l'aspect de cuisson artisanale et traditionnelle.There are two categories of ovens, namely static heating ovens and forced circulation ovens. In a static heating oven, a first battery of electrical resistors is arranged at the level of the ceiling of the enclosure while a second battery of electrical resistors is placed nearby and below a refractory slab on which the products to be cooked are placed, slab also called refractory hearth. The electrical resistances of the second The function of the battery is to heat the refractory slab. In the case of a bakery, we obtain at the end of cooking an aspect which is not homogeneous on the entire outer periphery of the product, in particular bread, the part in contact with the refractory tile having a more accentuated cooking surface. The use of this first category of static heating and hearth furnace refractory is therefore recommended when trying to give the product the appearance of traditional and traditional cooking.

Le four à circulation forcée comporte des résistances électriques et un système de ventilation faisant circuler l'air chauffé par lesdites résistances dans l'enceinte du four, ce qui assure une température sensiblement homogène dans tout le volume intérieur de ladite enceinte.The forced circulation oven has electrical resistances and a ventilation system circulating the air heated by said resistors in the oven enclosure, which ensures a substantially uniform temperature throughout the interior volume of said enclosure.

Indépendamment de la recherche de l'aspect de cuisson traditionnelle et artisanale, on utilise un type de four plutôt que l'autre en fonction des produits à cuire, par exemple les croissants, dans un four à circulation forcée, les pizzas dans un four à chauffage statique.Regardless of the search for the traditional cooking aspect and artisanal, we use one type of oven rather than the other depending on the products to be bake, for example croissants, in a forced circulation oven, pizzas in a static heating oven.

Ces deux catégories de fours ont une structure totalement différente, ce qui impose au constructeur des approvisionnements en composants et des circuits de fabrication indépendants et ce qui ne permet pas d'avoir une quelconque souplesse au niveau de la demande des clients.These two categories of ovens have a completely different structure, which which requires the manufacturer to supply components and circuits independent manufacturing and what does not allow to have any flexibility in terms of customer demand.

Le but que s'est fixé le demandeur est de pallier à ces inconvénients.The aim set by the applicant is to overcome these drawbacks.

Ce but est parfaitement atteint par le four à chauffage électrique de conception modulaire de l'invention. This goal is perfectly achieved by the electric heating oven of modular design of the invention.

Il s'agit d'un four qui comporte

  • a) une structure de base qui comporte un châssis ayant une ouverture frontale et n portes superposées pour la fermeture de ladite ouverture frontale, et
  • b) n modules, chacun étant monté dans le volume intérieur du châssis, en regard d'une porte donnée , lesdits modules étant choisis parmi les deux types suivants :
  • b1) un premier type de module pour cuisson à chauffage ventilé
  • comprenant :
    • un caisson ayant une ouverture frontale, équipé intérieurement d'une ou plusieurs résistances électriques et d'un système de ventilation et dont chaque montant latéral comporte x glissières pour x plaques de cuisson,
  • b2) un second type de module pour cuisson à chauffage statique
  • comprenant :
    • éventuellement une première batterie de résistances électriques
    • y ensembles comprenant chacun une sole réfractaire et une seconde batterie de résistances électriques disposées immédiatement sous ladite sole réfractaire, y étant égal ou supérieur à 1
    • éventuellement un caisson ayant une ouverture frontale et contenant les y ensembles et éventuellement la première batterie de résistances électriques.
    • This is an oven that has
  • a) a basic structure which comprises a frame having a front opening and n superimposed doors for closing said front opening, and
  • b) n modules, each being mounted in the interior volume of the chassis, facing a given door, said modules being chosen from the following two types:
  • b 1 ) a first type of module for ventilated heating cooking
  • including:
    • a box having a front opening, internally equipped with one or more electrical resistances and a ventilation system and each lateral upright of which comprises x slides for x cooking plates,
  • b 2 ) a second type of module for static heating cooking
  • including:
    • possibly a first battery of electrical resistors
    • y assemblies each comprising a refractory hearth and a second battery of electrical resistors arranged immediately under said refractory hearth, being there equal to or greater than 1
    • possibly a box having a front opening and containing the y sets and possibly the first battery of electrical resistors.

    • Ainsi la particularité de l'invention est de proposer un four qui peut se monter comme un prêt-à-monter (kit) , à partir d'une structure de base commune susceptible d'accueillir une pluralité de modules, chaque module étant choisi en fonction de la destination du four . Il s'agira d'un four qui sera totalement à circulation forcée, si les modules mis en place sont tous du premier type ; il s'agira d'un four qui sera totalement à chauffage statique si les modules mis en place sont tous du second type. Il s'agira d'un four mixte, à la fois à circulation forcée et à chauffage statique si les modules mis en place sont des deux types.Thus the particularity of the invention is to provide an oven which can be assemble as a ready-to-assemble (kit), from a common basic structure capable of accommodating a plurality of modules, each module being chosen in depending on the destination of the oven. It will be an oven which will be completely forced circulation, if the modules installed are all of the first type; it will be an oven which will be totally static heated if the modules installed are all of the second type. It will be a combi steamer, both forced circulation and static heating if the modules installed are of two types.

    D'ailleurs cette dernière structure , qui est caractéristique de l'invention, dans laquelle les n modules sont choisis parmi à la fois le premier module pour cuisson à chauffage ventilé et le second module pour cuisson à chauffage statique présente un avantage significatif pour l'utilisateur, puisqu'il peut , dans le même four, assurer la décongélation de ses produits dans le ou les modules du premier type et la finition artisanale et traditionnelle des produits décongelés dans le ou les modules du second type. Bien sûr, cela pourrait être fait à partir de deux fours distincts, chacun d'un type donné, mais dans le cas présent, cela peut se faire, sans manipulation excessive puisqu'il suffit uniquement de transférer les produits des plaques de cuisson sur les soles réfractaires, dans le même four.Moreover, this latter structure, which is characteristic of the invention, in which the n modules are chosen from both the first module for cooking with ventilated heating and the second module for cooking with static heating has a significant advantage for the user, since it can, in the same oven, ensure the thawing of its products in the module (s) of the first type and the artisanal and traditional finish of the thawed products in the module (s) of the second type. Of course, this could be done from two separate ovens, each of a given type, but in this case, it can be done without excessive handling since it is only enough to transfer the products from the cooking plates to the refractory soles, in the same furnace.

    Dans une variante préférée de réalisation d'un four dont la structure de base comporte deux portes superposées , le premier type de module comporte quatre plaques de cuisson et le second type de module comporte deux ensembles comprenant chacun une sole réfractaire et une seconde batterie de résistances électriques.In a preferred embodiment of an oven, the structure of which base has two superimposed doors, the first type of module has four hobs and the second type of module has two sets each comprising a refractory hearth and a second coil of resistors electric.

    La présente invention sera mieux comprise à la lecture de la description qui va être faite d'un exemple préféré de réalisation d'un four à chauffage électrique de conception modulaire illustré par le dessin annexé dans lequel la figure unique est une représentation schématique en perspective de la structure de base du four et de trois combinaisons de modules permettant de constituer trois types de fours différents.The present invention will be better understood on reading the description which will be made of a preferred embodiment of a heating oven electrical modular design illustrated by the accompanying drawing in which the single figure is a schematic perspective representation of the structure of base of the oven and three combinations of modules making it possible to constitute three different types of ovens.

    Il sera noté que la représentation qui est faite des différents composants du four de l'invention ,sur la figure unique, est une représentation particulièrement simplifiée et qui ne concerne strictement que les composants principaux qui sont caractéristiques de l'invention. N'ont pas été en particulier détaillés tous les composants habituels , qui sont bien connus de l'homme du métier , et qui entrent dans la composition des fours traditionnels soit à circulation forcée soit à chauffage statique par sole réfractaire.It will be noted that the representation which is made of the various components of the oven of the invention, in the single figure, is a particularly representation simplified and which strictly concerns only the main components which are features of the invention. In particular, not all of the usual components, which are well known to those skilled in the art, and which enter in the composition of traditional ovens either with forced circulation or with heating static by refractory hearth.

    Le premier composant du four de l'invention est la structure de base 1 qui comporte un châssis 2 avec une ouverture frontale 3, ladite ouverture pouvant être fermée par n portes superposées 4, le nombre n de portes 4 étant égal à deux dans l'exemple illustré sur la figure . Bien sûr chaque porte 4 est montée sur le châssis 2, latéralement le long de l'ouverture frontale 3 grâce à des charnières 5. Lesdites portes 4 possèdent leurs moyens de fermeture, dont seules les poignées 6 ont été illustrées, et leurs moyens d'étanchéité pour assurer la fermeture étanche du four lorsqu'elles sont toutes deux fermées.The first component of the oven of the invention is the basic structure 1 which comprises a frame 2 with a front opening 3, said opening being able to be closed by n superimposed doors 4, the number n of doors 4 being equal to two in the example illustrated in the figure. Of course each door 4 is mounted on the frame 2, laterally along the front opening 3 thanks to hinges 5. Said doors 4 have their closing means, of which only the handles 6 have been illustrated, and their means of sealing to ensure the watertight closing of the oven when both are closed.

    La structure de base 1 comporte également tous les moyens habituels en matière de commande électrique , de contrôle des fonctions marche / arrêt , de contrôle de la température... qui sont bien connus dans les fours à chauffage électrique. Dans l'exemple illustré , tous ces moyens ont été regroupés dans une portion latérale 2a du châssis 2 , adjacente à l'ouverture 3.The basic structure 1 also includes all the usual means for electrical control, control of on / off functions, temperature control, etc. which are well known in electrically heated ovens. In the example illustrated, these means have been grouped in a side portion 2a of the frame 2 adjacent to the opening 3.

    A partir de cette structure de base 1 , il est possible , par assemblage des autres composants qui vont être décrits maintenant , de réaliser trois types différents de fours , à savoir un four à circulation forcée, un four à soles réfractaires et un four mixte ayant un compartiment à circulation forcée et un compartiment à sole réfractaire.From this basic structure 1, it is possible, by assembling other components which will be described now, to realize three types different from ovens, namely a forced circulation oven, a deck oven refractories and a combi-furnace having a forced circulation compartment and a refractory hearth compartment.

    Ceci est obtenu grâce à deux types de modules qui sont conçus pour pouvoir être montés dans le volume intérieur du châssis 2.This is achieved through two types of modules which are designed to be able to be mounted in the interior volume of the chassis 2.

    Le premier type de module 7 est un module pour cuisson à circulation forcée . Il comporte un caisson 8 ayant une ouverture frontale 9 . La partie arrière 8a dudit caisson 8 est munie d'une ou plusieurs batteries de résistances électriques, non montrées sur la figure, et d'un système de ventilation 1O . Les deux montants latéraux 8b du caisson 8 comportent x glissières 11 , notamment des équerres, qui sont disposées en vis-à-vis de manière à ce que deux glissières 11 puissent supporter une même plaque de cuisson. Dans l'exemple illustré , le nombre x de glissières 11 est égal à 5, de sorte que le module 7 du premier type est destiné à recevoir cinq plaques de cuisson.The first type of module 7 is a module for forced circulation cooking. It comprises a box 8 having a front opening 9. The rear part 8 a of said box 8 is provided with one or more batteries of electrical resistors, not shown in the figure, and with a ventilation system 10. Both amounts side 8b of the box 8 x comprise runners 11, including brackets, which are disposed in facing relation so that the two slides 11 can support the same hotplate. In the example illustrated, the number x of slides 11 is equal to 5, so that the module 7 of the first type is intended to receive five cooking plates.

    Dans le premier exemple de four à circulation forcée , deux modules 7 du premier type sont montés dans le volume intérieur du châssis 2 de la structure de base 1 , l'ouverture frontale 9 de chaque module 7 étant en regard de chaque porte 4 de la structure de base 1. On dispose donc , en final, d'un four à deux portes et à huit plaques de cuisson, ledit four étant totalement à circulation forcée avec deux systèmes de ventilation 1O.In the first example of a forced circulation oven, two modules 7 of the first type are mounted in the interior volume of the chassis 2 of the structure of base 1, the front opening 9 of each module 7 being opposite each door 4 of the basic structure 1. There is therefore, ultimately, a two-door oven and eight hobs, said oven being totally forced circulation with two 1O ventilation systems.

    Le second type de module 21 est un module pour cuisson à chauffage statique qui comprend une première batterie 12 de trois résistances électriques 13 et y ensembles 14, chaque ensemble comprenant une sole réfractaire 15 et une seconde batterie 16 de résistances électriques , disposée immédiatement sous ladite sole réfractaire 15 à faible distance d de celle-ci. La batterie et les y ensembles sont montés de préférence dans un caisson (non représenté) similaire à celui 8 du premier module 7. Dans l'exemple illustré , le nombre y d'ensembles 14 est égal à deux . Il y a donc un ensemble inférieur 14' et un ensemble supérieur 14. Lorsque ce module 21 du second type est monté dans le volume intérieur du châssis 2 , en regard d'une porte 4 donnée , l'ensemble inférieur 14' est en partie basse de la portion de ce volume intérieur , tandis que l'ensemble supérieur 14 a une disposition intermédiaire à l'intérieur dudit volume entre la première batterie 12 de résistances électriques 13 et la sole réfractaire 15' du second ensemble 14'. La première batterie 12 de résistances électriques 13 est placée sous la paroi supérieure du châssis 2 ou, de préférence, du caisson du module 21.The second type of module 21 is a module for static heating cooking which comprises a first battery 12 of three electrical resistances 13 and y sets 14, each set comprising a refractory hearth 15 and a second battery 16 of electrical resistances, placed immediately under said refractory hearth 15 at a short distance d therefrom. The battery and the y assemblies are preferably mounted in a box (not shown) similar to that 8 of the first module 7. In the example illustrated, the number y of assemblies 14 is equal to two. There is therefore a lower assembly 14 'and an upper assembly 14. When this module 21 of the second type is mounted in the interior volume of the chassis 2, opposite a given door 4, the lower assembly 14' is partly lower portion of this interior volume, while the upper assembly 14 has an intermediate arrangement inside said volume between the first battery 12 of electrical resistors 13 and the refractory hearth 15 'of the second assembly 14'. The first battery 12 of electrical resistors 13 is placed under the upper wall of the chassis 2 or, preferably, of the box of the module 21.

    Le four de la seconde variante , illustré sur la figure , est composé en partie haute , en regard de la porte supérieure 4, d'un module 21 du second type, à chauffage statique et à sole réfractaire et en partie basse, en regard de la porte inférieure 4', d'un module 7 du premier type à circulation forcée. Selon cette seconde variante , on dispose donc d'un four mixte avec un compartiment à circulation forcée à quatre plaques de cuisson et un compartiment à deux soles réfractaires .The oven of the second variant, illustrated in the figure, is composed of upper part, opposite the upper door 4, of a module 21 of the second type, with static heating with refractory hearth and at the bottom, facing the door lower 4 ', of a module 7 of the first type with forced circulation. According to this second variant, so there is a combi steamer with a compartment for forced circulation with four hotplates and a compartment with two hearths refractory.

    Dans la troisième variante de réalisation , illustrée sur la figure , le four est entièrement à chauffage statique , étant équipé intérieurement de quatre soles réfractaires 15a à 15d, c'est-à-dire quatre ensembles comprenant chacun une sole réfractaire et une seconde batterie de résistances électriques disposée immédiatement sous ladite sole réfractaire à faible distance d de celle-ci. Il est à noter que dans les trois secondes batteries qui sont disposées immédiatement sous les trois soles réfractaires supérieures 15a, 15b, 15c , les résistances électriques servent à la fois au chauffage de la sole réfractaire 15a, 15b, 15c, sous laquelle elles sont immédiatement disposées et également au chauffage du volume qui est contenu entre ladite sole réfractaire et celle qu'elles surplombent. C'est ce dernier rôle qui est imparti à la première batterie de résistances électriques qui est située immédiatement sous la paroi supérieure du châssis 2. On comprend que lorsqu'on réalise un four ne comprenant que des soles réfractaires et des batteries de résistances électriques , telles que dans la troisième variante de réalisation - sans caisson -, les deux seconds modules 21 qui sont montés à l'intérieur de la structure de base 1 ne sont pas strictement identiques puisque le module supérieur comporte une première batterie 12 de résistances électriques 13 tandis que le second module, inférieur , n'en comporte pas.In the third variant embodiment, illustrated in the figure, the oven is entirely static heated, being fitted internally with four refractory hearths 15 a to 15 d , that is to say four assemblies each comprising a refractory hearth and a second battery of electrical resistors placed immediately under said refractory hearth at a short distance d therefrom. It should be noted that in the three second batteries which are placed immediately under the three upper refractory hearths 15 a , 15 b , 15 c , the electrical resistances are used both for heating the refractory hearth 15 a , 15 b , 15 c , under which they are immediately placed and also for heating the volume which is contained between said refractory hearth and that which they overhang. It is this latter role which is imparted to the first battery of electrical resistances which is situated immediately under the upper wall of the chassis 2. It is understood that when an oven is produced comprising only refractory hearths and batteries of electrical resistances, such as in the third variant embodiment - without box -, the two second modules 21 which are mounted inside the basic structure 1 are not strictly identical since the upper module comprises a first battery 12 of electrical resistors 13 while that the second, lower module does not have one.

    La structure de base 2 comporte nécessairement tous les moyens de montage et de connexion électrique des batteries de résistances électriques, des moyens de ventilation et des soles réfractaires.The basic structure 2 necessarily includes all the means of mounting and electrical connection of electrical resistance batteries, means of ventilation and refractory soles.

    De la matière isolante est disposée entre la structure de base 2 et les caissons 7 des modules et également entre les caissons superposés. Lors de la fermeture des portes 4,4', celles-ci s'appliquent sur les faces frontales des caissons, lesquelles sont avantageusement pourvues d'un joint d'étanchéité.Insulating material is placed between the base structure 2 and the boxes 7 of the modules and also between the superimposed boxes. When closing of the 4.4 'doors, these apply to the front faces of the boxes, which are advantageously provided with a seal.

    La présente invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits à titre d'exemples non exhaustifs, toutes sortes d'assemblages différents pouvant être obtenues à partir de la structure de base à n portes et des types de modules décrits ci-dessus, chaque module pouvant avoir un nombre différent x de plaques de cuisson et un nombre différent y d'ensembles à soles réfractaires.The present invention is not limited to the embodiments which have just been described by way of non-exhaustive examples, all kinds of different assemblies which can be obtained from the basic structure with n doors and from the types of modules. described above, each module possibly having a different number x of cooking plates and a different number y of refractory hearth assemblies.
