Description

La présente invention concerne les portes de fours électroménagers comprenant une coquille de forme parallépipèdique dont la paroi frontale présente une large ouverture ayant la forme d'un parallèlogramme et fermée par une plaque transparente.The present invention relates to the doors of household ovens comprising a shell of parallelepiped shape, the front wall of which has a large opening in the form of a parallelogram and closed by a transparent plate.

La fixation de ladite plaque transparente sur ladite coquille est généralement réalisée par des organes de fixation indépendants desdits deux éléments à assembler. Les organes de fixation utilisés sont généralement des dispositifs comprenant des vis et écrous de fixation exigeant des accessoires supplémentaires lors de l'assemblage ou bien des pattes soudées avec interposition de joints.
De plus lesdits organes de fixation sont difficiles à mettre en place et nécessitent un long temps de montage.The fixing of said transparent plate on said shell is generally carried out by fixing members independent of said two elements to be assembled. The fasteners used are generally devices comprising fixing screws and nuts requiring additional accessories during assembly or else welded lugs with interposition of seals.
Furthermore, said fixing members are difficult to install and require a long assembly time.

Le document US-A-2 394 176 montre une porte de four avec la plaque transparente disposée de façon amovible par coulissement par rapport à la coquille de la porte.Document US-A-2,394,176 shows an oven door with the transparent plate disposed in a removable manner by sliding relative to the shell of the door.

Le but de l'invention est de remédier aux inconvénients précités en réalisant une nouvelle conception d'une porte d'un four électroménager et en mettant en oeuvre un procédé simple de montage de ladite plaque transparente sur l'ouverture de la coquille parallépépidique.The object of the invention is to remedy the aforementioned drawbacks by realizing a new design for a door of a household appliance and by implementing a simple method of mounting said transparent plate on the opening of the parallelepidic shell.

Selon l'invention, la porte d'un four électroménager est caractérisée en ce que les organes de fixation sont formés d'au moins deux pattes de maintien agencées respectivement sur deux côtés opposés de la bordure interne et situées chacune à légère distance de cette bordure de manière à définir un logement ouvert en direction de ladite ouverture, tandis que la plaque transparente comporte sur deux côtés opposés et parallèles aux deux côtés portant les pattes au moins deux saillies destinées à venir se fixer, par coulissement de la plaque par rapport à la bordure interne, respectivement sous les deux pattes de maintien, ladite bordure interne et ladite plaque comportant des moyens de blocage mutuel.According to the invention, the door of a household appliance is characterized in that the fixing members are formed from at least two retaining tabs respectively arranged on two opposite sides of the internal border and each located a short distance from this border so as to define an open housing in the direction of said opening, while the transparent plate has on two opposite sides parallel to the two sides carrying the tabs at least two projections intended to be fixed, by sliding the plate relative to the internal border, respectively under the two retaining tabs, said border internal and said plate comprising mutual blocking means.

Grâce à cette porte de four électroménager selon l'invention, le nombre des pièces utiles à la fixation de la plaque transparente sur l'ouverture de la coquille de forme parallépipèdique est limité auxdites deux pièces ce qui simplifie le montage et diminue le temps d'assemblage desdites deux pièces ainsi que le coût d'assemblage et de fabrication de la porte du four électroménager.Thanks to this appliance oven door according to the invention, the number of parts useful for fixing the transparent plate to the opening of the shell of parallelepipedal shape is limited to said two parts which simplifies assembly and reduces the time of assembly of said two parts as well as the cost of assembling and manufacturing the door of the household appliance oven.

  • Figures 5a and 5b show the front faces of the door of a household appliance oven according to the invention.

Selon la Figure 1, une porte d'un four à micro-ondes comporte, une coquille 1, par exemple, en matière plastique de forme générale parallépipèdique à profil rectangulaire dont la paroi frontale 2 présente une large ouverture X de hauteur H₁ qui a une forme générale d'un parallélogramme rectangle et qui est fermée par une plaque transparente 3, par exemple, en polycarbonate, de forme complémentaire et montée sur la bordure interne 4 de ladite ouverture. Ladite plaque transparente 3 comporte des saillies 5 et 6 qui sont positionnées, dans des logements ouverts 5′ et 6′ délimités par l'espacement réalisé entre le bord interne 4 et des organes de fixation constitués, par exemple, des pattes de maintien 7, 8 et situés respectivement sur deux côtés opposés 9 et 10 de la bordure interne 4. La coquille 1 et la plaque transparente 3 présentent en section verticale et transversale aux côtés portant les pattes de maintien 7, 8 et les saillies 5, 6, un profil bombé vers l'extérieur.According to Figure 1, a door of a microwave oven comprises, a shell 1, for example, of plastic of generally rectangular shape with rectangular profile whose front wall 2 has a wide opening X of height H₁ which has a general shape of a rectangular parallelogram and which is closed by a transparent plate 3, for example, made of polycarbonate, of complementary shape and mounted on the internal edge 4 of said opening. Said transparent plate 3 comprises projections 5 and 6 which are positioned in open housings 5 ′ and 6 ′ delimited by the spacing produced between the internal edge 4 and fixing members constituted, for example, by holding tabs 7, 8 and located respectively on two opposite sides 9 and 10 of the internal border 4. The shell 1 and the transparent plate 3 have in vertical and transverse section at the sides carrying the holding tabs 7, 8 and the projections 5, 6, a profile bulging outwards.

La partie arrière 11 de la porte du four à micro-ondes comporte, en outre, une armature métallique 12 positionnée, par exemple, par fixation amovible, sur la coquille 1. Ladite armature 12 a une forme générale parallépipèdique et présente une large ouverture de hauteur H₂ qui a une forme générale d'un parallélogramme et qui est fermé par une plaque métallique perforée 13. Ladite plaque perforée présente des trous situés à égale distance les uns des autres de manière à éviter le passage des ondes provenant de la cavité de cuisson lorsque le four, dont la porte a été préalablement fermée, est sur le mode de fonctionnement micro-ondes et des moyens de fixation permettant une attache facile de la plaque métallique perforée 13 sur l'armature 12. L'armature métallique 12 comporte, également, sur son pourtour, un décrochement 14 correspondant à un piège à quart d'ondes de type connu permettant de capter les fuites d'ondes lorsque la porte est fermée, évitant ainsi tout risque desdites fuites d'ondes vers l'extérieur du four.The rear part 11 of the microwave oven door further comprises a metal frame 12 positioned, for example, by removable fixing, on the shell 1. Said frame 12 has a generally parallelepiped shape and has a wide opening of height H₂ which has a general shape of a parallelogram and which is closed by a perforated metal plate 13. Said perforated plate has holes located at equal distance from each other so as to avoid the passage of waves from the cooking cavity when the oven, whose door has been previously closed, is in the microwave operating mode and fixing means allowing easy attachment of the perforated metal plate 13 on the frame 12. The metal frame 12 also includes, on its periphery, a recess 14 corresponding to a quarter-wave trap of known type making it possible to capture the leaks of waves when the door is closed, thus avoiding any risk of said wave leaks to the outside of the oven.

Un cadre 15, par exemple, en matière plastique, de forme générale parallépipèdique est positionnée, par exemple par fixation amovible, sur l'armature métallique 12 de manière que les côtés opposés 16 et 17 du cadre 15 viennent respectivement en contact sur un bord inférieur 18 de la coquille 1 et en appui sur un bord supérieur 19 de la coquille 1. L'encastrement des différents éléments précités permet à la partie arrière 11 de la porte d'avoir une surface plane.A frame 15, for example, made of plastic, of generally parallelepipedal shape is positioned, for example by removable fixing, on the metal frame 12 so that the opposite sides 16 and 17 of the frame 15 come into contact respectively on a lower edge 18 of the shell 1 and resting on an upper edge 19 of the shell 1. The embedding of the various aforementioned elements allows the rear part 11 of the door to have a flat surface.

Selon la Figure 2, seule la coquille 1 et la plaque transparente 3 sont représentées. La coquille 1 comporte des organes de fixation constitués, par exemple, de huit pattes de maintien P₁, P₂, P₃, P₄, P₅, P₆, P₇ et P₈ agencés respectivement sur les deux côtés opposés 9 et 10 de la bordure interne 4.
Le nombre de pattes de maintien est nullement limitatif. D'autres agencements peuvent être envisagés, la seule condition à respecter étant la position d'au moins une patte de maintien sur chacun des deux côtés opposés 9 et 10 de la bordure interne 4.According to Figure 2, only the shell 1 and the transparent plate 3 are shown. The shell 1 comprises fixing members constituted, for example, by eight holding tabs P₁ , P₂ , P₃ , P₄ , P₅ , P₆ , P₇ and P₈ respectively arranged on the two opposite sides 9 and 10 of the internal border 4.
The number of holding tabs is in no way limiting. Other arrangements can be envisaged, the only condition to be respected being the position of at least one retaining tab on each of the two opposite sides 9 and 10 of the internal border 4.

La coquille 1 comporte, également, sur l'un des côtés de sa bordure interne 4 une dépression formant un logement 20 positionnée sur la bordure transversale le long d'une des parois latérales 21 du bord interne 4 de la coquille 1 sur une faible largeur 1 et sur toute la longueur de la large ouverture de hauteur H₁, le logement 20 ayant une profondeur e correspondant sensiblement à l'épaisseur de la plaque transparente 3 et un moyen de verrouillage, par exemple, une languette 22 située sensiblement au milieu de la bordure interne 4 de la paroi latérale 23 opposée à la paroi latérale 21. D'autres moyens de verrouillage, par exemple, une lame montée fixe à une extrémité sur la bordure interne et pivotante autour de cette extrémité de manière à bloquer après rotation de la lame le mouvement de ladite plaque (3), peuvent être utilisés.The shell 1 also comprises, on one of the sides of its internal edge 4, a depression forming a housing 20 positioned on the transverse edge along one of the side walls 21 of the internal edge 4 of the shell 1 over a small width 1 and over the entire length of the wide opening H hauteur height, the housing 20 having a depth e corresponding substantially to the thickness of the transparent plate 3 and a locking means, for example, a tongue 22 located substantially in the middle of the inner edge 4 of the opposite side wall 23 to the side wall 21. Other locking means, for example, a blade mounted fixed at one end on the internal edge and pivoting around this end so as to block, after rotation of the blade, the movement of said plate (3) , can be used.

La plaque transparente 3 comporte, par exemple, huit saillies S₁, S₂, S₃, S₄, S₅, S₆, S₇ et S₈ agencées respectivement sur les deux côtés opposés 24 et 25 de la plaque transparente 3. Des remarques identiques à celles faites pour les pattes de maintien de la coquille 1 peuvent être formulées pour les saillies de la plaque transparente.
Lesdites saillies sont positionnées sur la plaque transparente 3 de manière à venir, après encastrement, en vis à vis des pattes de maintien.The transparent plate 3 comprises, for example, eight projections S₁ , S₂ , S₃ , S₄ , S₅ , S₆ , S₇ and S₈ arranged respectively on the two opposite sides 24 and 25 of the transparent plate 3. Remarks identical to those made for the shell retaining lugs 1 can be formulated for the projections of the transparent plate.
Said projections are positioned on the transparent plate 3 so as to come, after embedding, opposite the retaining tabs.

De plus, la plaque transparente comporte deux décrochements 26 et 27 situés en vis à vis et positionnés respectivement sur les extrémités des côtés opposés 24 et 25 de ladite plaque 3 en liaison avec un des côtés latéraux 28 de la plaque 3, et un decrochement 29 réalisé sur le deuxième côté latéral 30 de la plaque 3 et placé en regard de la languette 22, la languette 22 et ledit decrochement 29 constituant des moyens de blocage mutuel de la plaque transparente par rapport à la coquille.In addition, the transparent plate has two recesses 26 and 27 located opposite and positioned respectively on the ends of the opposite sides 24 and 25 of said plate 3 in connection with one of the lateral sides 28 of the plate 3, and a recess 29 produced on the second lateral side 30 of the plate 3 and placed opposite the tongue 22, the tongue 22 and said recess 29 constituting means for mutual locking of the transparent plate with respect to the shell.

Le montage de la plaque transparente 3 sur la coquille 1 se réalise de la manière suivante. La coquille 1 est placée dans un plan P de manière à présenter sa face avant interne. La plaque transparente 3 est positionnée dans un plan P′ faisant un angle α avec le plan P, la forme bombée de la plaque transparente 3 étant positionnée en regard de la face avant interne de la coquille 1. Le côté latéral libre 28 en liaison avec les décrochements 26 et 27 est présenté en vis à vis de la paroi latérale 21 de la coquille 1 contenant l'encoche 20 et vient en appui contre le bord interne 4 de la coquille 1. Ledit côté latéral 28 étant dans la position indiquée, la plaque transparente 3 effectue un mouvement de rotation suivant une flèche F.
Selon la figure 3, le mouvement de rotation de la plaque transparente 3 est d'un angle - α de manière que les plans P et P′ respectivement de la coquille 1 et de la plaque transparente 3 soient confondus. La plaque transparente 3 repose ainsi en partie sur le bord interne 4 de la coquille 1. Les saillies S1 à S8 de la plaque transparente 3 sont placées dans le même alignement que les pattes de maintien P1 à P8 mais de façon décalée. La plaque transparent 3 subit un mouvement de translation suivant une flèche T1 de manière que les saillies S1 à S8 de la plaque transparente 3 s'encastrent dans les logements réalisés entre le bord interne 4 et les pattes de maintien P1 à P8. La plaque transparente 3 se trouve ainsi dans la position représentée à la figure 4, les pattes de maintien P₁ à P₈ et les saillies S₁ à S₈ étant en prise les unes avec les autres.The mounting of the transparent plate 3 on the shell 1 is carried out as follows. The shell 1 is placed in a plane P so as to present its internal front face. The transparent plate 3 is positioned in a plane P ′ making an angle α with the plane P , the convex shape of the transparent plate 3 being positioned opposite the internal front face of the shell 1. The free lateral side 28 in connection with the recesses 26 and 27 is presented opposite the side wall 21 of the shell 1 containing the notch 20 and bears against the internal edge 4 of the shell 1. Said lateral side 28 being in the position indicated, the transparent plate 3 performs a rotational movement along an arrow F.
According to Figure 3, the rotational movement of the transparent plate 3 is at an angle - α so that the planes P and P 'respectively of the shell 1 and the transparent plate 3 are combined. The transparent plate 3 thus partially rests on the internal edge 4 of the shell 1. The projections S1 to S8 of the transparent plate 3 are placed in the same alignment as the holding tabs P1 to P8 but in an offset manner. The transparent plate 3 undergoes a translational movement along an arrow T1 so that the projections S1 to S8 of the transparent plate 3 fit into the housings produced between the internal edge 4 and the holding tabs P1 to P8 . The transparent plate 3 is thus in the position shown in Figure 4, the holding tabs P₁ to P₈ and the projections S₁ to S₈ being engaged with each other.

Selon cette même figure 4, la plaque transparente 3 est représentée en position verrouillée, c'est à dire que ladite plaque 3 ne peut pas effectuer de mouvement dans son emplacement qui est ainsi limité, d'une part, par la languette 22 et, d'autre part, par les deux décrochements 26 et 27 venant en butée contre les bords 30 et 31 du logement 20 représentés à la figure 2.According to this same FIG. 4, the transparent plate 3 is shown in the locked position, that is to say that said plate 3 cannot perform any movement in its location which is thus limited, on the one hand, by the tongue 22 and, on the other hand, by the two recesses 26 and 27 abutting against the edges 30 and 31 of the housing 20 shown in FIG. 2.

Selon la Figure 5a, la coquille 1 de la porte du four électroménager selon l'invention présente, sur sa face avant A, une bordure externe 32 dont la forme générale est un U couché. La plaque transparente 3 est monté dans le logement 20 prévu à cet effet dont une arête 33 est représentée en pointillés.According to Figure 5a, the shell 1 of the door of the household appliance oven according to the invention has, on its front face A , an outer edge 32 whose general shape is a coated U. The transparent plate 3 is mounted in the housing 20 provided for this purpose, an edge 33 is shown in dotted lines.

Selon la Figure 5b, dans un autre exemple de réalisation, la bordure externe 32 de la coquille 1 du four présentant la même forme que celle décrite dans la Figure 5a, possède son ouverture, située au dessous du logement 20, qui comporte une nervure 34 formant joint pour le côté latéral 28 de la plaque 3. Ladite nervure 34 a une hauteur sensiblement égale à la profondeur e du logement 20 et une longueur sensiblement égale à la hauteur H₁ de l'ouverture de la paroi frontale 2 de la coquille. Cette nervure 34 dont les bords supérieurs sont légèrement arrondis et dont le côté latéral 28 de la plaque 3 n'est plus dans le prolongement de la paroi latérale 21 du bord interne 4 grâce au joint ainsi formé, permet également d'obtenir un bord non coupant de la paroi latérale 21.According to Figure 5b, in another embodiment, the outer edge 32 of the shell 1 of the oven having the same shape as that described in Figure 5a, has its opening, located below the housing 20, which has a rib 34 forming a seal for the lateral side 28 of the plate 3. Said rib 34 has a height substantially equal to the depth e of the housing 20 and a length substantially equal to the height H₁ of the opening of the front wall 2 of the shell. This rib 34, the upper edges of which are slightly rounded and the lateral side 28 of the plate 3 is no longer in the extension of the lateral wall 21 of the internal edge 4 thanks to the seal thus formed, also makes it possible to obtain a non-edge cutting from the side wall 21.

L'invention s'applique à toutes les portes de fours électroménagers et plus particulièrement à celle d'un four à micro-ondes.The invention applies to all the doors of household ovens and more particularly to that of a microwave oven.
