Description

La présente invention concerne une porte pour enceinte de cuisson.The present invention relates to a door for a cooking chamber.

Elle concerne également un four de cuisson domestique, et notamment un four à pyrolyse, comprenant une telle porte pour enceinte de cuisson.It also relates to a domestic cooking oven, and in particular a pyrolysis oven, comprising such a door for cooking chamber.

De manière générale, la présente invention s'applique à une porte adaptée à fermer une enceinte de cuisson d'un appareil de cuisson domestique, du type four domestique électrique ou à gaz.In general, the present invention applies to a door adapted to close a cooking chamber of a domestic cooking appliance, of the electric or gas domestic oven type.

Elle trouve son application, de manière non limitative, dans un four électrique à pyrolyse, dans lequel la température à l'intérieur de l'enceinte peut atteindre 500° C lors des cycles de pyrolyse.It finds its application, without limitation, in an electric pyrolysis furnace, in which the temperature inside the chamber can reach 500 ° C during pyrolysis cycles.

Une porte pour enceinte de cuisson comprend ainsi un panneau extérieur, un cadre de porte solidaire du panneau extérieur et un panneau intérieur obturant la face avant de l'enceinte de cuisson.A door for a cooking chamber thus comprises an outer panel, a door frame secured to the outer panel and an inner panel closing the front face of the cooking chamber.

On connait une telle porte pour enceinte de cuisson dans le document EP 1 783 433 A1 .We know such a door for cooking enclosure in the document EP 1 783 433 A1 .

Dans ce document, outre le panneau extérieur et le panneau intérieur, la porte pour enceinte de cuisson comprend un ou plusieurs panneaux intermédiaires permettant de manière connue de créer des lames d'air isolantes à l'intérieur de la porte, et ainsi de limiter la montée en température de la porte, notamment au niveau du panneau extérieur.In this document, in addition to the outer panel and the inner panel, the cooking chamber door comprises one or more intermediate panels making it possible in known manner to create insulating air gaps inside the door, and thus to limit the temperature rise of the door, especially at the level of the outer panel.

Le document EP 1 783 433 propose ainsi une porte pour enceinte de cuisson permettant un montage et démontage simplifié d'un panneau intermédiaire en vue de faciliter le nettoyage de la porte pour enceinte de cuisson.The document EP 1 783 433 proposes a door for a cooking chamber for easy assembly and disassembly of an intermediate panel to facilitate cleaning of the door for cooking chamber.

Toutefois, pour accéder au panneau intermédiaire, il est nécessaire de monter le panneau intérieur de manière amovible sur le cadre de porte.However, to access the intermediate panel, it is necessary to mount the inner panel removably on the door frame.

Dans le document EP 1 783 433 , le panneau intérieur est monté de manière amovible dans une rainure formée par une barrette longitudinale disposée le long d'un bord supérieur de la porte, c'est-à-dire le bord placé horizontalement et en partie haute de l'appareil de cuisson lorsque la porte obture l'enceinte de cuisson.In the document EP 1 783 433 , the inner panel is removably mounted in a groove formed by a longitudinal bar disposed along an upper edge of the door, that is to say the edge placed horizontally and in the upper part of the cooking appliance when the door closes the cooking chamber.

Un clip est destiné à maintenir par pincement le panneau intérieur dans le cadre de porte au niveau du bord inférieur de la porte.A clip is for pinching the inner panel in the door frame at the lower edge of the door.

Le clip est par exemple monté par collage au cadre de porte.The clip is for example mounted by gluing to the door frame.

Toutefois, les montages amovibles d'un panneau de porte pour enceinte de cuisson mettant en oeuvre des techniques de collage sont problématiques en terme de coût et de tenue à la température.However, the removable assemblies of a door panel for cooking chamber using bonding techniques are problematic in terms of cost and withstand temperature.

En effet, les importantes variations de température auxquelles est soumise la colle de fixation ont pour effet de dégrader la colle, entrainant à terme le décollage des éléments de fixation.In fact, the large temperature variations to which the fixing adhesive is subjected have the effect of degrading the adhesive, ultimately leading to the release of the fasteners.

On connait également dans le document DE 3 238 441 A1 un panneau extérieur de porte pour enceinte de cuisson monté de manière amovible sur un rebord d'un panneau intérieur.We also know in the document DE 3,238,441 A1 an exterior cooking chamber door panel removably mounted to a rim of an interior panel.

Un clip de fixation est collé sur la vitre du panneau extérieur et comporte une languette élastique destinée à coopérer avec une encoche du rebord du panneau intérieur.A fixing clip is glued to the window of the outer panel and has an elastic tongue for cooperating with a notch of the edge of the inner panel.

Toutefois, le panneau intérieur n'est pas démontable. Or ce panneau intérieur en contact direct avec l'intérieur de l'enceinte de cuisson est soumis à de fortes salissures et son nettoyage est rendu difficile.However, the interior panel is not removable. However, this inner panel in direct contact with the interior of the cooking chamber is subjected to heavy soiling and cleaning is made difficult.

Par ailleurs, outre les inconvénients déjà précités liés à l'utilisation de la colle pour fixer le clip de fixation sur la vitre du panneau extérieur, le nettoyage du panneau extérieur est rendu difficile par le clip de fixation collé sur le panneau, créant des obstacles piégeant les salissures.Moreover, in addition to the aforementioned drawbacks relating to the use of the glue to fix the fastening clip on the glass of the outer panel, the cleaning of the outer panel is made difficult by the fixing clip glued to the panel, creating obstacles trapping dirt.

On notera qu'il est également connu d'équiper une porte pour enceinte de cuisson d'un panneau intérieur vitré monté sur un cadre démontable.Note that it is also known to equip a cooking chamber door with a glazed interior panel mounted on a removable frame.

Toutefois, l'utilisateur doit alors démonter l'ensemble constitué par le panneau intérieur vitré et le cadre.However, the user must then dismantle the assembly consisting of the glazed interior panel and the frame.

Là encore, le nettoyage du panneau intérieur vitré est rendu difficile par la présence du cadre.Again, the cleaning of the glazed interior panel is made difficult by the presence of the frame.

La présente invention a pour but de résoudre au moins certains des inconvénients précités et de proposer une porte pour enceinte de cuisson ayant un panneau intérieur simple à monter et démonter.The present invention aims to solve at least some of the aforementioned drawbacks and to provide a door for a cooking chamber having a simple inner panel to mount and dismount.

A cet effet, la présente invention concerne une porte pour enceinte de cuisson comprenant un panneau extérieur, un cadre de porte solidaire du panneau extérieur et un panneau intérieur monté de manière amovible sur le cadre de porte.To this end, the present invention relates to a cooking chamber door comprising an outer panel, a door frame secured to the outer panel and an inner panel removably mounted on the door frame.

Selon l'invention, la porte pour enceinte de cuisson comprend un élément de fixation du panneau intérieur à un rebord du cadre de porte, l'élément de fixation comportant une patte s'étendant dans un plan perpendiculaire audit panneau intérieur, ladite patte comportant une languette élastique en saillie du plan de ladite patte dans une position de montage, la languette élastique étant logée dans un orifice du rebord du cadre de porte dans la position de montage, l'élément de fixation comportant également des moyens formant pince à une extrémité de la patte, l'élément de fixation étant monté sur le panneau intérieur par insertion d'un bord du panneau intérieur dans les moyens formant pince.According to the invention, the cooking chamber door comprises an element for fixing the inner panel to a rim of the door frame, the fixing element comprising a tab extending in a plane perpendicular to said inner panel, said tab comprising a an elastic tongue projecting from the plane of said tab in a mounting position, the resilient tongue being housed in an orifice of the rim of the door frame in the mounting position, the fixing element also comprising means forming a clip at one end of the tab, the fastener being mounted to the inner panel by inserting an edge of the inner panel into the clip means.

Ainsi, grâce à un élément de fixation mettant en oeuvre une languette élastique en saillie, on obtient des moyens de montage par clipsage de la languette élastique dans un orifice du rebord du cadre de porte, permettant un démontage facilité du panneau intérieur et un positionnement fiable contre un rebord du cadre de porte.Thus, thanks to a fastening element implementing a projecting resilient tongue, mounting means are obtained by clipping the elastic tongue into a hole in the rim of the door frame, allowing easy disassembly of the inner panel and reliable positioning. against a rim of the door frame.

De plus, l'élément de fixation est maintenu par pincement sur un bord du panneau intérieur, assurant un montage fiable et une bonne tenue dans le temps du montage du panneau intérieur dans le cadre de porte.In addition, the fastening element is held by pinching on an edge of the inner panel, ensuring reliable mounting and good durability of the assembly of the inner panel in the door frame.

La porte pour enceinte de cuisson peut ainsi être nettoyée facilement, grâce à l'extraction du panneau intérieur démontable du cadre de porte, le panneau intérieur subissant traditionnellement le plus de salissures et projections de graisse du fait de son positionnement obturant l'enceinte de cuisson.The cooking chamber door can thus be easily cleaned, by extracting the removable inner panel from the door frame, the inner panel having traditionally undergone the most dirt and grease splashes due to its positioning closing the cooking chamber. .

Après démontage du panneau intérieur, l'élément de fixation peut être démonté du bord du panneau intérieur. Les moyens formant pince peuvent être déclipser du bord du panneau intérieur. Celui-ci est ainsi libre de tout élément de fixation, facilitant le nettoyage sur toute la surface du panneau intérieur.After dismounting the inner panel, the fastener can be removed from the edge of the inner panel. The clamp means can be unclipped from the edge of the inner panel. It is thus free of any fastener, facilitating cleaning on the entire surface of the inner panel.

Dans un mode de réalisation pratique, l'orifice traverse le rebord dans une direction perpendiculaire au plan de la patte de l'élément de fixation.In a practical embodiment, the orifice passes through the flange in a direction perpendicular to the plane of the lug of the fastener.

L'utilisateur peut ainsi accéder par l'orifice traversant à la patte de l'élément de fixation et agir sur la languette élastique en saillie pour permettre l'extraction de la languette élastique de l'orifice, et ainsi le démontage du panneau intérieur.The user can thus access through the through hole to the tab of the fastener and act on the protruding elastic tongue to allow the extraction of the elastic tongue of the orifice, and thus the disassembly of the inner panel.

Dans un mode de réalisation pratique de l'invention, la languette élastique comprend une première extrémité solidaire de la patte et comporte une aile recourbée à une seconde extrémité libre, ladite aile recourbée étant adaptée à venir en contact avec un bord de l'orifice du rebord du cadre de porte.In a practical embodiment of the invention, the elastic tongue comprises a first end secured to the tab and comprises a wing curved at a second free end, said curved wing being adapted to come into contact with an edge of the opening of the edge of the door frame.

La coopération de la languette élastique avec l'orifice du rebord est ainsi réalisée grâce à une aile recourbée en contact avec un bord de l'orifice, assurant un positionnement fiable et un blocage du panneau intérieur monté dans le cadre de porte.The cooperation of the elastic tongue with the orifice of the rim is thus achieved by means of a curved wing in contact with an edge of the orifice, ensuring a reliable positioning and blocking of the inner panel mounted in the door frame.

En pratique, la porte pour enceinte de cuisson comprend deux éléments de fixation montés respectivement à deux angles d'un même côté du panneau intérieur.In practice, the cooking chamber door comprises two fixing elements mounted respectively at two angles on the same side of the inner panel.

Le montage par des éléments de fixation placés à deux angles du panneau intérieur permet d'assurer un montage fiable et sécurisé du panneau intérieur dans le cadre de porte.The mounting by two-angled fasteners of the inner panel ensures reliable and secure mounting of the inner panel in the door frame.

A contrario, il est nécessaire d'agir sur les deux éléments de fixation pour obtenir le démontage du panneau intérieur, évitant ainsi toute manipulation accidentelle, provoquant le démontage du panneau intérieur.Conversely, it is necessary to act on the two fasteners to obtain disassembly of the inner panel, thus avoiding any accidental manipulation, causing disassembly of the inner panel.

Selon une autre caractéristique avantageuse de l'invention, la porte pour enceinte de cuisson comprend au moins deux éléments de maintien adaptés à maintenir au moins un panneau intermédiaire dans le cadre de porte entre le panneau extérieur et le panneau intérieur, lesdits au moins deux éléments de maintien étant comprimés contre le panneau intérieur.According to another advantageous characteristic of the invention, the cooking chamber door comprises at least two holding elements adapted to maintain at least one intermediate panel in the door frame between the outer panel and the inner panel, said at least two elements keeping tabs pressed against the inner panel.

Les éléments de maintien exercent ainsi une force de pression contre le panneau intérieur, dans une direction sensiblement perpendiculaire au panneau intérieur.The holding members thus exert a pressing force against the inner panel, in a direction substantially perpendicular to the inner panel.

La force de pression induit un effort de traction, dans la direction perpendiculaire au panneau intérieur, du panneau intérieur sur l'élément de fixation, et notamment sur la patte s'étendant dans un plan perpendiculaire au panneau intérieur.The pressure force induces a tensile force, in the direction perpendicular to the inner panel, of the inner panel on the fastener, and in particular on the tab extending in a plane perpendicular to the inner panel.

Cet effort de traction a pour effet de renforcer la coopération de la languette élastique en saillie logée dans l'orifice du rebord du cadre de porte et ainsi de bloquer mécaniquement l'élément de fixation dans le rebord du cadre de porte.This tensile force has the effect of reinforcing the cooperation of the protruding elastic tongue housed in the orifice of the rim of the door frame and thus mechanically lock the fastener element in the rim of the door frame.

La coopération renforcée de la languette élastique avec l'orifice du rebord du cadre de porte est encore améliorée lorsque la languette élastique comporte une aile recourbée adaptée à venir en contact avec un bord de l'orifice du rebord du cadre de porte.The reinforced cooperation of the elastic tongue with the opening of the rim of the door frame is further improved when the elastic tongue comprises a curved wing adapted to come into contact with an edge of the orifice of the rim of the door frame.

L'aile recourbée forme ainsi une surface ou plan venant en butée contre le bord de l'orifice, la mise en butée étant renforcée grâce à l'effort de traction appliqué sur la patte de l'élément de fixation.The curved wing thus forms a surface or plane abutting against the edge of the orifice, the abutment being reinforced by the tensile force applied to the tab of the fastener.

Selon un mode de réalisation permettant de renforcer encore le blocage mécanique de l'élément de fixation dans le rebord du cadre de porte, deux éléments de fixation sont montés respectivement à deux angles d'un même côté du panneau intérieur et deux éléments de maintien sont logés respectivement dans deux angles opposés du cadre de porte, en vis-à-vis respectivement des deux angles d'un même côté du panneau intérieur.According to an embodiment for further reinforcing the mechanical locking of the fastening element in the rim of the door frame, two fixing elements are respectively mounted at two angles on the same side of the inner panel and two holding elements are respectively housed in two opposite corners of the door frame, vis-à-vis respectively the two corners of the same side of the inner panel.

Dans un mode de réalisation pratique, les éléments de maintien sont en silicone.In a practical embodiment, the holding elements are made of silicone.

Selon une autre caractéristique avantageuse de l'invention, le rebord s'étend le long d'un bord supérieur du cadre de porte.According to another advantageous characteristic of the invention, the flange extends along an upper edge of the door frame.

Ainsi, l'utilisateur accède aisément aux éléments de fixation pour le montage et démontage du panneau intérieur sur le cadre de porte.Thus, the user easily accesses the fasteners for mounting and dismounting the inner panel on the door frame.

En effet, lorsque la porte pour enceinte de cuisson est en position ouverte, le rebord s'étendant le long du bord supérieur du cadre de porte se trouve en vis-à-vis de l'utilisateur et est facilement accessible.Indeed, when the cooking chamber door is in the open position, the flange extending along the upper edge of the door frame is vis-à-vis the user and is easily accessible.

De préférence, le rebord est un profilé formant déflecteur.Preferably, the rim is a deflector section.

Selon un second aspect, la présente invention concerne également un four de cuisson domestique, notamment four à pyrolyse, comprenant une porte pour enceinte de cuisson telle que décrite précédemment.According to a second aspect, the present invention also relates to a domestic cooking oven, in particular a pyrolysis oven, comprising a door for a cooking chamber as described above.

Le four de cuisson domestique présente des caractéristiques et avantages analogues à ceux décrits précédemment en relation avec la porte pour enceinte de cuisson.The domestic cooking oven has features and advantages similar to those previously described in connection with the cooking chamber door.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will become apparent in the description below.

On va décrire tout d'abord en référence à la figure 1 une porte pour enceinte de cuisson selon un mode de réalisation de l'invention.We will first describe with reference to the figure 1 a door for a cooking chamber according to an embodiment of the invention.

La porte peut être prévue pour équiper un appareil de cuisson domestique, tel qu'un four à gaz ou un four électrique.The door may be adapted to equip a domestic cooking appliance, such as a gas oven or an electric oven.

La figure 1 illustre en perspective une porte 10 pour enceinte de cuisson désolidarisée de l'enceinte de cuisson.The figure 1 illustrates in perspective a door 10 for cooking chamber disengaged from the cooking chamber.

La porte 10 comprend un panneau extérieur 11, un cadre de porte 12 solidaire du panneau extérieur 11 et un panneau intérieur 13.The door 10 comprises an outer panel 11, a door frame 12 integral with the outer panel 11 and an inner panel 13.

Le panneau intérieur 13 est destiné à obturer l'enceinte de cuisson et est donc placé en vis-à-vis des aliments à cuire.The inner panel 13 is intended to close the cooking chamber and is therefore placed vis-à-vis the food to be cooked.

Le panneau intérieur 13 est donc soumis à des projections et salissures, nécessitant un nettoyage régulier.The inner panel 13 is therefore subjected to projections and dirt, requiring regular cleaning.

La porte 10 pour enceinte de cuisson peut également comprendre un ou plusieurs panneaux intermédiaires maintenus dans le cadre de porte 12, entre le panneau extérieur 11 et le panneau intérieur 12.The cooking chamber door 10 may also comprise one or more intermediate panels held in the door frame 12, between the outer panel 11 and the inner panel 12.

Ici, de manière non limitative, la porte 10 comprend un panneau intermédiaire 10'.Here, without limitation, the door 10 comprises an intermediate panel 10 '.

Ce type de configuration est utilisé classiquement dans une porte pour enceinte de cuisson afin de limiter la montée en température de celle-ci.This type of configuration is conventionally used in a door for a cooking chamber in order to limit the rise in temperature thereof.

Une telle porte pour enceinte de cuisson, à un ou plusieurs panneaux intermédiaires, est décrite notamment dans le document EP 1 783 433 A1 dont le contenu est incorporé par référence à la présente description.Such a door for a cooking chamber, with one or more intermediate panels, is described in particular in the document EP 1 783 433 A1 whose contents are incorporated by reference into the present description.

En référence aux figures 6A et 6B, on désignera dans la suite de la description par côté inférieur 10a de la porte 10, le côté de la porte destiné à être monté en partie basse d'une enceinte de cuisson 61, généralement autour d'un axe de rotation horizontal permettant le déplacement de la porte 10 entre une position fermée, dans laquelle la porte s'étend verticalement pour obturer l'enceinte de cuisson 61, et une position ouverte, dans laquelle la porte 10 s'étend horizontalement, perpendiculairement à la face avant de l'enceinte de cuisson 61.With reference to Figures 6A and 6B , in the description of the lower side 10a of the door 10, the side of the door intended to be mounted in the lower part of a cooking chamber 61, generally around a horizontal axis of rotation allowing the displacement of the door 10 between a closed position, in which the door extends vertically to close the cooking chamber 61, and an open position, in which the door 10 extends horizontally, perpendicularly to the front face of the enclosure cooking 61.

La porte 10 pour enceinte de cuisson comporte ainsi à l'opposé du côté inférieur 10a, un côté supérieur 10b, destiné à venir en partie haute de l'enceinte de cuisson lorsque la porte 10 obture l'enceinte de cuisson.The door 10 for a cooking chamber thus has on the opposite side of the lower side 10a, an upper side 10b, intended to come to the upper part of the cooking chamber when the door 10 closes the cooking chamber.

Le cadre de porte 12 s'étend à la périphérie de la porte 10 et est solidaire du panneau extérieur 11.The door frame 12 extends around the periphery of the door 10 and is integral with the outer panel 11.

En particulier, le cadre de porte 12 comprend un bord supérieur 12b sur le côté supérieur 10b de la porte 10.In particular, the door frame 12 comprises an upper edge 12b on the upper side 10b of the door 10.

Comme bien illustré aux figures 2 et 3, le bord supérieur 12b du cadre de porte 12 comprend un rebord 20.As well illustrated at Figures 2 and 3 the upper edge 12b of the door frame 12 comprises a flange 20.

Le rebord 20 forme ainsi un pourtour en saillie sur le cadre de porte 12.The flange 20 thus forms a periphery projecting from the door frame 12.

Le rebord 20 s'étendant le long du bord supérieur 12b du cadre de porte 12 constitue ici un profilé formant déflecteur.The flange 20 extending along the upper edge 12b of the door frame 12 here constitutes a profile forming deflector.

Un tel déflecteur placé sur le côté supérieur 10b de la porte 10 est connu et permet d'orienter l'air en sortie de l'enceinte de cuisson.Such a deflector placed on the upper side 10b of the door 10 is known and allows to direct the air output of the cooking chamber.

A titre d'exemple, le rebord 20 constitue un déflecteur en thermoplastique ou thermodurcissable ou encore en métal.For example, the flange 20 is a deflector thermoplastic or thermosetting or metal.

Le panneau intérieur 13 est monté de manière amovible sur le cadre de porte 12.The inner panel 13 is removably mounted on the door frame 12.

Le côté inférieur 10a de la porte 10 comporte un logement 15 d'un bord inférieur 13a du panneau intérieur 13.The lower side 10a of the door 10 has a housing 15 with a lower edge 13a of the inner panel 13.

Le bord inférieur 13a du panneau intérieur 13 peut ainsi être glissé à l'intérieur d'une rainure formant logement 15.The lower edge 13a of the inner panel 13 can thus be slid inside a housing groove 15.

Le logement 15 permet ainsi de maintenir en position le panneau intérieur 13 au niveau de son bord inférieur 13a.The housing 15 thus allows to maintain in position the inner panel 13 at its lower edge 13a.

Afin de maintenir le panneau intérieur 13 dans le cadre de porte 12, la porte comprend au moins un élément de fixation 30 monté sur un bord supérieur 13b du panneau intérieur 13.In order to maintain the inner panel 13 in the door frame 12, the door comprises at least one fastening element 30 mounted on an upper edge 13b of the inner panel 13.

On va décrire à présent en référence aux figures 4A et 4B un élément de fixation 30 selon un exemple de réalisation non limitatif.We will now describe with reference to Figures 4A and 4B a fastening element 30 according to a non-limiting exemplary embodiment.

L'élément de fixation 30 comporte une patte 31 s'étendant sensiblement dans un plan, vertical aux figures 4A et 4B.The fastening element 30 comprises a tab 31 extending substantially in a plane, vertical to the Figures 4A and 4B .

L'élément de fixation 30 comporte dans ce mode de réalisation des moyens formant pince 32 à une première extrémité 31 a de la patte 31.In this embodiment, the fastening element 30 comprises clamp means 32 at a first end 31a of the tab 31.

Dans ce mode de réalisation, les moyens formant pince 32 comprennent une aile plane 33 solidaire de l'extrémité 31a de la patte 31 et s'étendant sensiblement perpendiculairement à la patte 31.In this embodiment, the clamp means 32 comprise a flat wing 33 secured to the end 31a of the tab 31 and extending substantially perpendicular to the tab 31.

L'aile plane 33 comporte une ou plusieurs languettes flexibles 34.The planar wing 33 has one or more flexible tongues 34.

Les languettes flexibles 34 sont repliées à partir de l'aile plane 33 et s'étendent globalement parallèlement à l'aile plane 33.The flexible tongues 34 are bent from the plane wing 33 and extend generally parallel to the plane wing 33.

L'espace formé entre l'aile plane 33 et chaque languette flexible 34 constitue ainsi des moyens formant pince 32.The space formed between the plane wing 33 and each flexible tongue 34 thus constitutes gripper means 32.

Comme cela sera décrit ultérieurement notamment en référence à la figure 5, les moyens formant pince 32 sont adaptés à être montés sur le panneau intérieur 13 de la porte 10 par insertion d'un bord du panneau intérieur 13 dans les moyens formant pince 32.As will be described later in particular with reference to the figure 5 the gripper means 32 are adapted to be mounted on the inner panel 13 of the door 10 by inserting an edge of the inner panel 13 in the gripper means 32.

Dans ce mode de réalisation, l'élément de fixation 30 comporte deux languettes flexibles 34 disposées de part et d'autre de la patte 31.In this embodiment, the fastening element 30 comprises two flexible tongues 34 disposed on either side of the tab 31.

Par ailleurs, dans ce mode de réalisation, la patte 31 comprend à une seconde extrémité 31b, opposée à la première extrémité 31a, une aile recourbée 31 c. L'aile recourbée 31 c forme ainsi une aile de retour à partir de la seconde extrémité 31 b et s'étend dans un plan légèrement incliné par rapport au plan de la patte 31.Furthermore, in this embodiment, the tab 31 comprises at a second end 31b, opposite the first end 31a, a curved wing 31c. The curved wing 31c thus forms a return wing from the second end 31b and extends in a plane slightly inclined with respect to the plane of the tab 31.

Comme cela sera décrit ultérieurement notamment en référence à la figure 5, l'aile recourbée 31 c est adaptée à être insérée dans un logement du cadre de porte 12.As will be described later in particular with reference to the figure 5 the curved wing 31c is adapted to be inserted into a housing of the door frame 12.

Par ailleurs, la patte 31 comporte une languette élastique 35 s'étendant en saillie du plan de la patte 31 dans une position de repos.Furthermore, the tab 31 comprises an elastic tongue 35 projecting from the plane of the tab 31 in a rest position.

Les figures 4A et 4B illustrent ainsi l'élément de fixation dans une position de repos ou position stable, dans laquelle la languette élastique 35 s'étend en saillie de la patte 31.The Figures 4A and 4B thus illustrate the fastening element in a position of rest or stable position, in which the elastic tongue 35 projects from the tab 31.

La languette élastique 35 comprend une première extrémité 35a solidaire de la patte 31.The elastic tongue 35 comprises a first end 35a integral with the tab 31.

Dans ce mode de réalisation, la patte 31 comporte une échancrure 36, la languette élastique 35 s'étendant à partir d'un bord 36a de l'échancrure 36. Le bord 36a de l'échancrure 36 est ainsi confondu avec la première extrémité 35a de la languette élastique 35.In this embodiment, the tab 31 comprises a notch 36, the elastic tongue 35 extending from an edge 36a of the notch 36. The edge 36a of the notch 36 is thus merged with the first end 35a of the elastic tongue 35.

Par ailleurs, à une seconde extrémité libre 35b, opposée à la première extrémité 35a, la languette élastique 35 comporte une aile recourbée 37.Moreover, at a second free end 35b, opposite to the first end 35a, the elastic tongue 35 has a curved wing 37.

Dans ce mode de réalisation, la languette élastique 35 comporte ainsi une portion principale s'étendant, selon une première direction, à partir de la première extrémité 35a solidaire de la patte 31 et une aile recourbée 37, s'étendant sensiblement perpendiculairement à la portion principale de la languette élastique 35.In this embodiment, the elastic tongue 35 thus comprises a main portion extending, in a first direction, from the first end 35a integral with the tab 31 and a curved wing 37, extending substantially perpendicular to the portion principal of the elastic tongue 35.

Comme bien illustré à la figure 4B et à la figure 5, l'aile recourbée 37 comporte en outre dans ce mode de réalisation une extrémité terminale 37a formant un angle avec l'aile recourbée 37.As well illustrated at the Figure 4B and at the figure 5 the curved wing 37 further comprises in this embodiment a terminal end 37a forming an angle with the curved wing 37.

Comme visible à la figure 4B, dans une position de repos dans laquelle la languette élastique 35 est en saillie de la patte 31, l'extrémité terminale 37a s'étend sensiblement parallèlement au plan de la patte 31.As visible at Figure 4B in a rest position in which the elastic tongue 35 projects from the tab 31, the end end 37a extends substantially parallel to the plane of the tab 31.

Lorsque l'élément de fixation 30 est en tôle métallique, il peut être réalisé par pliage et découpage de la tôle pour former les moyens formant pince 32 ainsi que la languette élastique 35.When the fastening element 30 is made of sheet metal, it can be made by folding and cutting the sheet to form the gripper means 32 and the elastic tongue 35.

En particulier, la languette 35 peut être réalisée à partir d'une découpe dans le plan de la patte 31, venant de la formation de l'échancrure 36.In particular, the tongue 35 can be made from a cut in the plane of the tab 31, coming from the formation of the notch 36.

On va décrire à présent en référence à la figure 5 le montage d'un tel élément de fixation 30 sur un panneau intérieur 13.We will now describe with reference to the figure 5 mounting such a fastener 30 on an inner panel 13.

Comme bien illustré à la figure 5, lorsque l'élément de fixation 30 est monté sur le panneau intérieur 13, la patte 31 s'étend dans un plan perpendiculaire au panneau intérieur 13.As well illustrated at the figure 5 when the fastening element 30 is mounted on the inner panel 13, the tab 31 extends in a plane perpendicular to the inner panel 13.

Par ailleurs, les moyens formant pince 32 sont montés sur le panneau intérieur 13 par insertion d'un bord du panneau intérieur 13 dans les moyens formant pince 32.Furthermore, the clamp means 32 are mounted on the inner panel 13 by inserting an edge of the inner panel 13 in the clamp means 32.

Dans le mode de réalisation tel que décrit précédemment en référence aux figures 2 et 3, un bord supérieur 13b du panneau intérieur 13 est inséré dans les moyens formant pince 32.In the embodiment as described above with reference to Figures 2 and 3 an upper edge 13b of the inner panel 13 is inserted into the clamp means 32.

La patte 31 est insérée dans un logement 22 du rebord 20 du cadre de porte 12.The tab 31 is inserted into a housing 22 of the rim 20 of the door frame 12.

Dans cette position de montage, la languette élastique 35 de l'élément de fixation 30 est logée dans un orifice 21 du rebord 20 du cadre de porte 12, l'orifice 21 s'étendant en vis-à-vis du logement 22.In this mounting position, the resilient tongue 35 of the fixing element 30 is housed in an orifice 21 of the rim 20 of the door frame 12, the orifice 21 extending opposite the housing 22.

L'orifice 21 forme ainsi une encoche à l'intérieur du rebord 20 avec un bord 21 a débouchant dans le logement 22.The orifice 21 thus forms a notch inside the flange 20 with an edge 21 opening into the housing 22.

Comme bien illustré aux figures 2 et 5, l'orifice 21 traverse le rebord 20 dans une direction perpendiculaire au plan de la patte 31 de l'élément de fixation 30.As well illustrated at figures 2 and 5 the orifice 21 passes through the flange 20 in a direction perpendicular to the plane of the tab 31 of the fastening element 30.

Ainsi, la languette élastique 35 est logée à une extrémité de l'orifice 21 traversant le rebord 20.Thus, the elastic tongue 35 is housed at one end of the orifice 21 passing through the rim 20.

Plus précisément, dans ce mode de réalisation dans lequel la languette élastique 35 comporte une aile recourbée 37, l'aile recourbée 37 est adaptée à venir en contact avec le bord 21 a de l'orifice 21 du rebord 20 du cadre de porte 12.More specifically, in this embodiment in which the elastic tongue 35 comprises a curved wing 37, the curved wing 37 is adapted to come into contact with the edge 21a of the orifice 21 of the rim 20 of the door frame 12.

Le bord 21a forme ainsi une butée de maintien en position de la languette élastique 35 dans l'orifice 21 par coopération du bord 21a avec l'aile recourbée 37.The edge 21a thus forms a stop for holding the elastic tongue 35 in the orifice 21 by the edge 21a cooperating with the curved wing 37.

En outre, l'extrémité terminale 37a de l'aile recourbée 37 permet de limiter le mouvement d'insertion de la languette élastique 35 dans l'orifice 21.In addition, the end end 37a of the curved wing 37 makes it possible to limit the insertion movement of the elastic tongue 35 into the orifice 21.

Enfin, la seconde extrémité 31 b de la patte 31 et l'aile recourbée 31 c sont insérées dans le logement 22 du rebord 20 du cadre de porte 12.Finally, the second end 31b of the tab 31 and the curved wing 31c are inserted into the housing 22 of the flange 20 of the door frame 12.

Le logement 22 comprenant une paroi 22a s'étendant sensiblement en vis-à-vis de l'orifice 21, l'aile recourbée 31 c vient en appui élastique contre la paroi 22a. Dans cette position, l'aile recourbée 31 c s'étend sensiblement parallèlement au plan de la patte 31. L'aile recourbée 31 c exerce ainsi une contrainte élastique au niveau de la seconde extrémité 31 b de la patte 31 et permet le maintien en position de la languette élastique 35 dans l'orifice 21 du rebord 20 du cadre de porte 12.The housing 22 comprising a wall 22a extending substantially vis-à-vis the orifice 21, the curved wing 31 c bears elastically against the wall 22a. In this position, the curved wing 31c extends substantially parallel to the plane of the tab 31. The curved wing 31c thus exerts an elastic stress at the second end 31b of the tab 31 and allows the maintenance position of the elastic tongue 35 in the orifice 21 of the rim 20 of the door frame 12.

Par ailleurs, dans ce mode de réalisation, comme bien illustré à la figure 5, la porte 10 comprend un élément de maintien 40 adapté à maintenir au moins un panneau intermédiaire 10' (ici au nombre de deux) dans le cadre de porte 12 entre le panneau extérieur 11 et le panneau intérieur 13.Moreover, in this embodiment, as well illustrated in the figure 5 , the door 10 comprises a holding element 40 adapted to maintain the at least one intermediate panel 10 '(here two in number) in the door frame 12 between the outer panel 11 and the inner panel 13.

L'élément de maintien 40 est comprimé contre le panneau intérieur 13.The holding element 40 is compressed against the inner panel 13.

A titre d'exemple, l'élément de maintien 40 est en silicone et comporte une ou plusieurs encoches 41 dans sa hauteur pour permettre de loger un coin d'un panneau intermédiaire 10'.For example, the holding member 40 is made of silicone and has one or more notches 41 in its height to accommodate a corner of an intermediate panel 10 '.

On se reportera avantageusement à la description du document EP 1 783 433 pour le montage d'un tel panneau intermédiaire dans l'élément de maintien.We will refer to the description of the document EP 1 783 433 for mounting such an intermediate panel in the holding member.

L'élément de maintien 40 est ainsi maintenu comprimé entre le panneau extérieur 11 et le panneau intérieur 13 de la porte 10.The holding element 40 is thus kept compressed between the outer panel 11 and the inner panel 13 of the door 10.

Comme bien illustré par la flèche F à la figure 5, la compression de l'élément de maintien 40 a pour effet d'exercer une force contre le panneau intérieur 13, tendant à écarter le panneau intérieur 13 du cadre de porte 12.As illustrated by arrow F at figure 5 , the compression of the holding member 40 has the effect of exerting a force against the inner panel 13, tending to spread the inner panel 13 of the door frame 12.

Cette force de compression induit un effort de traction sur l'élément de fixation 30, et notamment dans le plan vertical dans lequel s'étend la patte 31.This compression force induces a tensile force on the fastening element 30, and in particular in the vertical plane in which the tab 31 extends.

Ainsi, l'effort de traction est transmis à la languette 35 qui coopère en butée au niveau de l'aile recourbée 37 avec un bord 21 a de l'orifice 21.Thus, the tensile force is transmitted to the tongue 35 which cooperates abutting at the level of the curved wing 37 with an edge 21a of the orifice 21.

L'effort de traction a ainsi pour effet de renforcer la fixation du panneau intérieur 13 dans le cadre de porte 12 grâce à la force exercée au niveau de la butée de la languette élastique 35 dans l'orifice 21.The tensile force thus has the effect of reinforcing the fixing of the inner panel 13 in the door frame 12 thanks to the force exerted on the abutment of the elastic tongue 35 in the orifice 21.

La porte pour enceinte de cuisson comprend de préférence deux éléments de fixation 30, symétriques, montés respectivement à deux angles d'un même côté du panneau intérieur 13.The cooking chamber door preferably comprises two symmetrical fixing elements 30, respectively mounted at two angles on one and the same side of the inner panel 13.

Dans ce mode de réalisation, les deux éléments de fixation sont montés respectivement aux deux angles d'un bord supérieur 13b du panneau intérieur 13.In this embodiment, the two fastening elements are respectively mounted at the two corners of an upper edge 13b of the inner panel 13.

De manière similaire, la porte 10 peut également comporter deux éléments de maintien 40 logés respectivement à deux angles opposés du cadre de porte 12, en vis-à-vis respectivement des deux angles du bord supérieur 13b du panneau intérieur 13.Similarly, the door 10 may also comprise two holding elements 40 respectively housed at two opposite corners of the frame. door 12, vis-à-vis respectively the two corners of the upper edge 13b of the inner panel 13.

Dans ce mode de réalisation, la porte 10 comporte quatre éléments de maintien 40 logés respectivement aux quatre angles du cadre de porte 12 et adaptés à maintenir ici deux panneaux intermédiaires 10'.In this embodiment, the door 10 has four holding members 40 respectively housed at the four corners of the door frame 12 and adapted to hold here two intermediate panels 10 '.

Ainsi, la fixation du panneau intérieur 13 est réalisée symétriquement sur deux angles opposés du panneau intérieur 13, ici correspondant aux angles du bord supérieur 13b du panneau intérieur 13.Thus, the fixing of the inner panel 13 is carried out symmetrically on two opposite angles of the inner panel 13, here corresponding to the angles of the upper edge 13b of the inner panel 13.

Comme schématisé aux figures 6A et 6B, le rebord 20 du cadre de porte 12 comprend alors deux orifices 21 adaptés respectivement à loger une languette élastique 35 des deux éléments de fixation 30.As schematized at Figures 6A and 6B , the rim 20 of the door frame 12 then comprises two orifices 21 adapted respectively to accommodate an elastic tongue 35 of the two fastening elements 30.

Chaque orifice 21 traverse le rebord 20 et débouche au niveau du côté supérieur 10b de la porte 10.Each orifice 21 passes through the rim 20 and opens at the upper side 10b of the door 10.

On va décrire à présent, le montage et démontage d'un panneau intérieur 13 d'une porte 10 pour enceinte de cuisson d'un four de cuisson domestique 60 (illustré schématiquement aux figures 6A et 6B).We will now describe the assembly and disassembly of an inner panel 13 of a door 10 for a cooking chamber of a domestic cooking oven 60 (shown schematically in FIGS. Figures 6A and 6B ).

Le four de cuisson 60 comporte ainsi une enceinte de cuisson 61 obturée par une porte 10.The baking oven 60 thus comprises a cooking chamber 61 closed by a door 10.

Comme schématisé à la figure 6A, lorsque la porte est ouverte, l'utilisateur peut appliquer une force sur chaque languette élastique 35 des éléments de fixation 30.As schematized at Figure 6A when the door is opened, the user can apply a force on each elastic tongue 35 of the fastening elements 30.

Les orifices 21 débouchant vers le côté supérieur 10b de la porte 10, le démontage du panneau intérieur 13 peut être ainsi obtenu en insérant simultanément ou alternativement deux outils pointus (du type tournevis) dans les orifices 21 et en appuyant sur chaque languette élastique 35.The orifices 21 opening towards the upper side 10b of the door 10, the disassembly of the inner panel 13 can thus be obtained by simultaneously or alternately inserting two pointed tools (of the screwdriver type) in the orifices 21 and pressing on each resilient tongue 35.

La languette élastique 35 est escamotée dans l'échancrure 36 de l'élément de fixation 30 et est ainsi délogée de chaque orifice 21.The elastic tongue 35 is retracted into the notch 36 of the fixing element 30 and is thus dislodged from each orifice 21.

Le panneau intérieur 13 peut être soulevé au niveau du bord supérieur 13b du panneau intérieur 13.The inner panel 13 can be raised at the upper edge 13b of the inner panel 13.

On notera que dans le mode de réalisation mettant en oeuvre un élément de maintien 40 comprimé entre le panneau extérieur 11 et le panneau intérieur 11, le soulèvement du panneau intérieur 13 est facilité par la force de compression selon la flèche F exercée par l'élément de maintien 40 contre le panneau intérieur 13.Note that in the embodiment implementing a holding member 40 compressed between the outer panel 11 and the inner panel 11, the lifting of the inner panel 13 is facilitated by the force of compression according to the arrow F exerted by the holding member 40 against the inner panel 13.

Ensuite, le panneau intérieur peut être retiré en délogeant le bord inférieur 13a du logement 15 disposé sur le côté inférieur 10a de la porte 10.Then, the inner panel can be removed by dislodging the lower edge 13a of the housing 15 disposed on the lower side 10a of the door 10.

A contrario, lors du montage du panneau intérieur 13 sur la porte 10, le bord inférieur 13a du panneau intérieur 13 est tout d'abord inséré dans le logement 15.Conversely, during assembly of the inner panel 13 on the door 10, the lower edge 13a of the inner panel 13 is first inserted into the housing 15.

Le panneau intérieur 13 est alors fixé au cadre de porte 12 par appui sur le bord supérieur 13b du panneau intérieur 13.The inner panel 13 is then fixed to the door frame 12 by pressing on the upper edge 13b of the inner panel 13.

Les languettes élastiques 35 sont insérées dans le logement 22 du cadre de porte 12 jusqu'à être placées en vis-à-vis de chaque orifice 21.The resilient tongues 35 are inserted into the housing 22 of the door frame 12 until they are placed opposite each orifice 21.

Chaque languette élastique 35 est alors rappelée en saillie pour être logée dans l'orifice 21 dans la position de montage du panneau intermédiaire 13 dans le cadre de porte 12.Each resilient tab 35 is then protruded to be accommodated in the orifice 21 in the mounting position of the intermediate panel 13 in the door frame 12.

Bien entendu, la présente invention n'est pas limitée aux exemples de réalisation décrits précédemment.Of course, the present invention is not limited to the embodiments described above.

En particulier, le rebord comportant un orifice pour coopérer avec une languette élastique d'un élément de fixation peut s'étendre le long d'un bord latéral du cadre de porte, ou encore le long d'un côté inférieur de la porte.In particular, the flange having an orifice for cooperating with an elastic tongue of a fastener may extend along a side edge of the door frame, or along a lower side of the door.
