Description

L'invention se rapporte aux appareils de cuisson tels que, par exemple, des fours comprenant une enceinte de cuisson ouverte sur sa face frontale et comportant au moins un élément électrique de chauffage ayant une enveloppe tubulaire en matériau fragile du type quartz ou verre, qui contient un fil chauffant et dont les extrémités sont reliées respectivement à deux bouchons disposés chacun à une extrémité de l'enveloppe, chaque bouchon étant adapté à être monté dans un support solidaire de ladite enceinte de manière à maintenir ladite enveloppe à distance de la paroi interne de l'enceinte.The invention relates to cooking appliances such as, for example, ovens comprising a cooking enclosure open on its front face and comprising at least one electrical heating element having a tubular envelope of fragile material of the quartz or glass type, which contains a heating wire and the ends of which are respectively connected to two plugs each disposed at one end of the envelope, each plug being adapted to be mounted in a support integral with said enclosure so as to keep said envelope away from the internal wall of the enclosure.

Jusqu'à présent, dans des fours (ou grils) de ce genre, l'élément électrique à enveloppe fragile fait saillie dans l'enceinte et risque d'être endommagé lorsque l'utilisateur manipule sans précaution le plat du mets à cuire, ou bien lorsque ce dernier procède au nettoyage de l'enceinte. Ceci est d'autant plus important pour un élément de chauffage à quartz dont l'enveloppe ne doit pas être touchée par les doigts de la main.Until now, in ovens (or grills) of this kind, the electric element with a fragile envelope protrudes into the enclosure and risks being damaged when the user carelessly handles the dish of the food to be cooked, or when the latter cleans the enclosure. This is all the more important for a quartz heating element whose envelope must not be touched by the fingers of the hand.

De plus, ces fours ne répondent pas aux dernières normes de sécurité qui exigent une certaine protection électrique et/ou mécanique de l'élément de chauffage.In addition, these ovens do not meet the latest safety standards which require some electrical and / or mechanical protection of the heating element.

L'invention a donc pour but de supprimer ces inconvénients et de rendre ces fours conformes aux normes actuelles.The invention therefore aims to eliminate these drawbacks and make these ovens conform to current standards.

Selon l'invention l'enveloppe tubulaire est enfermée dans une cage dont la paroi est suffisamment ajourée pour laisser passer le rayonnement infrarouge vers l'intérieur de l'enceinte, et suffisamment rigide pour résister à un éventuel choc mécanique, ladite cage comportant des moyens de fixation sur ladite paroi interne de l'enceinte.According to the invention the tubular envelope is enclosed in a cage whose wall is sufficiently perforated to allow the infrared radiation to pass inside the enclosure, and rigid enough to withstand a possible mechanical shock, said cage comprising means fixing on said inner wall of the enclosure.

Ainsi, l'enveloppe tubulaire fragile est protégée contre tout choc ou manipulation de l'utilisateur, et l'élément de chauffage satisfait ainsi aux normes de sécurité.Thus, the fragile tubular casing is protected against any impact or manipulation by the user, and the heating element thus meets safety standards.

En outre, un autre avantage lié à cette protection de l'enveloppe est la possibilité pour le fabricant d'utiliser un élément de chauffage à enveloppe quartz dont l'épaisseur est voisine de un millimètre au lieu des deux millimètres ordinairement proposés, et donc de diminuer le prix de revient de l'élément de chauffage.In addition, another advantage linked to this protection of the envelope is the possibility for the manufacturer to use a heating element with a quartz envelope whose thickness is close to one millimeter instead of the two millimeters ordinarily offered, and therefore lower the cost price of the heating element.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence au dessin annexé dans lequel :

  • la Figure 1 est une coupe verticale schématique d'un appareil de cuisson selon l'invention et illustrant deux éléments de chauffage enfermés respectivement dans deux cages de protection ;
  • la Figure 2 représente en perspective et à plus grande échelle une cage de protection selon l'invention ;
  • la Figure 3 est une coupe partielle verticale selon la ligne III-III de la Figure 1, mais avec la cage non encore fixée définitivement sur l'enceinte.
The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended drawing in which:
  • Figure 1 is a schematic vertical section of a cooking appliance according to the invention and illustrating two heating elements enclosed respectively in two protective cages;
  • Figure 2 shows in perspective and on a larger scale a protective cage according to the invention;
  • Figure 3 is a partial vertical section along line III-III of Figure 1, but with the cage not yet permanently fixed on the enclosure.

L'appareil de cuisson représenté à la Figure 1 est un four ménager présentant une enceinte de cuisson 1 qui est ouverte sur sa face frontale et dont la paroi interne forme la voûte 3, la sole 4, le fond 5 et les deux côtés 6 et 7, ladite face frontale pouvant être fermée par une porte 8 (schématisée en traits interrompus).The cooking appliance represented in FIG. 1 is a household oven having a cooking enclosure 1 which is open on its front face and the internal wall of which forms the vault 3, the bottom 4, the bottom 5 and the two sides 6 and 7, said front face being able to be closed by a door 8 (shown diagrammatically in broken lines).

Cette enceinte de cuisson 1 comprend au moins un élément électrique de chauffage 9 comportant une enveloppe tubulaire 10 en matériau fragile du type quartz ou verre, qui contient un fil chauffant 11 et dont les extrémités 12 et 13 sont reliées respectivement à deux bouchons 14 et 15 disposés chacun à une extrémité de l'enveloppe, chaque bouchon 14, 15 étant adapté à être monté dans un support 16, 17 solidaire de ladite enceinte 1 de manière à maintenir ladite enveloppe 10 à distance de la paroi interne de l'enceinte.This cooking chamber 1 comprises at least one electrical heating element 9 comprising a tubular casing 10 of fragile material of the quartz or glass type, which contains a heating wire 11 and the ends 12 and 13 of which are connected respectively to two plugs 14 and 15 each disposed at one end of the envelope, each plug 14, 15 being adapted to be mounted in a support 16, 17 secured to said enclosure 1 so as to keep said envelope 10 away from the internal wall of the enclosure.

Comme on le voit et de manière à obtenir un meilleur chauffage, l'enceinte de cuisson 1 contient deux éléments de chauffage 9 dont l'enveloppe tubulaire 10 présente la forme d'un barreau droit, les bouchons 14 et 15 étant supportés par les supports 16 et 17 agencés sur les côtés 6 et 7 de l'enceinte 1 de manière à maintenir les deux enveloppes 10 parallèles entre elles et à distance de la voûte 3.As can be seen and in order to obtain better heating, the cooking chamber 1 contains two heating elements 9, the tubular casing 10 of which has the shape of a straight rod, the plugs 14 and 15 being supported by the supports 16 and 17 arranged on the sides 6 and 7 of the enclosure 1 so as to keep the two envelopes 10 parallel to each other and at a distance from the arch 3.

Les éléments 9 représentés sont du type à enveloppe quartz, mais pourraient aussi être du type à halogène à enveloppe verre.The elements 9 shown are of the quartz envelope type, but could also be of the glass envelope halogen type.

Selon l'invention, l'enveloppe tubulaire 10 de l'élément de chauffage 9 est enfermée dans une cage 18 dont la paroi 19 est suffisamment ajourée pour laisser passer le rayonnement infrarouge vers l'intérieur de l'enceinte 1, et suffisamment rigide pour résister à un éventuel choc mécanique, ladite cage 18 comportant des moyens de fixation sur la paroi interne de l'enceinte. La cage 18 est de préférence réalisée en tôle et comporte une patte P de mise à la terre destinée à être reliée électriquement à l'enceinte 1, par exemple, au moyen d'une vis.According to the invention, the tubular casing 10 of the heating element 9 is enclosed in a cage 18 whose wall 19 is sufficiently perforated to allow the infrared radiation to pass inside the enclosure 1, and sufficiently rigid to resist a possible mechanical shock, said cage 18 comprising fixing means on the wall internal speaker. The cage 18 is preferably made of sheet metal and has a grounding lug P intended to be electrically connected to the enclosure 1, for example, by means of a screw.

La cage 18 présente la forme d'une gouttière dont la paroi 19 présente des perforations 20 et chevauche à distance la paroi latérale 21 de l'enveloppe tubulaire 10 tournée vers l'intérieur de l'enceinte, et dont les bords longitudinaux 22, 23 comportent les moyens de fixation.
Comme on le voit mieux sur la Figure 2, les moyens de fixation sont formés par des ergots 24, 25 pratiqués sur les bords longitudinaux 22 et 23 de la gouttière, tandis que la paroi interne de l'enceinte formant la voûte 3 présente des fentes 26 adaptées à recevoir les ergots 24 et 25 ainsi que la patte P de mise à la terre.The cage 18 has the shape of a gutter whose wall 19 has perforations 20 and overlaps at a distance the side wall 21 of the tubular casing 10 facing towards the inside of the enclosure, and whose longitudinal edges 22, 23 include the fixing means.
As best seen in Figure 2, the fixing means are formed by lugs 24, 25 formed on the longitudinal edges 22 and 23 of the gutter, while the inner wall of the enclosure forming the vault 3 has slots 26 adapted to receive the pins 24 and 25 as well as the grounding lug P.

Pour fixer la cage 18 contre la voûte 3, on procède à une déformation des ergots 24, 25 par torsion pour les amener dans une direction transversale aux fentes 26 (position illustrée en traits plein sur la Figure 1 et en traits interrompus sur la Figure 3). Puis on rabat la patte P par pliage sur la voûte 3, et on assure au moyen de la vis la connexion électrique de mise à la terre.To fix the cage 18 against the arch 3, the lugs 24, 25 are deformed by twisting to bring them in a direction transverse to the slots 26 (position illustrated in solid lines in Figure 1 and in broken lines in Figure 3 ). Then the flap P is folded down by folding on the arch 3, and the electrical connection for grounding is provided by means of the screw.

Pour garantir l'application des bords 22 et 23 de la gouttière contre la voûte 3 et rattraper un éventuel jeu dû au découpage industriel des ergots et de la tôle constituant la cage, la paroi de l'enceinte, dans le cas présent la voûte 3, comporte des bossages 27 situés respectivement à proximité des fentes 26 sur lesquelles viennent s'appuyer, après torsion, lesdits ergots.To guarantee the application of the edges 22 and 23 of the gutter against the vault 3 and to make up for any play due to the industrial cutting of the pins and of the sheet metal constituting the cage, the wall of the enclosure, in this case the vault 3 , includes bosses 27 located respectively near the slots 26 on which come to bear, after twisting, said pins.

Pour garantir une certaine rigidité à la cage 18 tout en réduisant au minimum le rayonnement infrarouge nécessaire à la cuisson, le fond de la gouttière présente une plage 28 non perforée s'étendant longitudinalement à ladite enveloppe, tandis que les perforations 20 sont formées par des lumières oblongues disposées transversalement à l'enveloppe tubulaire 10 et symétriquement par rapport à cette plage 28.To guarantee a certain rigidity in the cage 18 while minimizing the infrared radiation necessary for cooking, the bottom of the gutter has a non-perforated area 28 extending longitudinally to said envelope, while the perforations 20 are formed by lights oblong arranged transversely to the tubular casing 10 and symmetrically with respect to this area 28.

En outre, de manière à satisfaire aux normes de sécurité actuelles, on a choisi de donner aux lumières 20 une largeur inférieure à cinq millimètres, et à la distance d entre la face interne de la gouttière et la paroi latérale 21 de l'enveloppe 10 une valeur supérieure à quatre millimètres.In addition, in order to meet current safety standards, it has been chosen to give the lights 20 a width of less than five millimeters, and at the distance d between the internal face of the gutter and the side wall 21 of the casing 10. a value greater than four millimeters.

Ainsi, comme on le comprendra, grâce à la cage 18 qui prend appui sur la voûte 3, on obtient une protection efficace contre tout choc mécanique éventuel et également contre des coups appliqués par "un appareil de choc à ressort" destiné à vérifier la conformité aux normes du four.Thus, as will be understood, thanks to the cage 18 which rests on the arch 3, effective protection is obtained against any possible mechanical shock and also against blows applied by "a spring shock device" intended to verify compliance. to oven standards.

En outre, grâce à cette cage 18, on peut réduire, dans le cas des enveloppes en quartz, l'épaisseur de ladite enveloppe afin d'utiliser des tubes moins onéreux, par exemple, on choisit une épaisseur de un millimètre au lieu de deux. Bien entendu, on pourra prévoir d'autres variantes de réalisation de la cage sans sortir du cadre des équivalents techniques, telles que, par exemple : une cage unique enveloppant deux enveloppes parallèles ; une cage formée d'un treillis métallique ou de tôle déployée ; et d'autres moyens de fixation contre l'une des parois de l'enceinte.In addition, thanks to this cage 18, it is possible to reduce, in the case of quartz envelopes, the thickness of said envelope in order to use less expensive tubes, for example, a thickness of one millimeter is chosen instead of two . Of course, other variants of the cage can be provided without departing from the framework of technical equivalents, such as, for example: a single cage enveloping two parallel envelopes; a cage formed by a wire mesh or expanded sheet; and other fixing means against one of the walls of the enclosure.
