Description

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

De manière générale, elle concerne 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, it relates to a door adapted to close a cooking chamber of a domestic cooking appliance, such as domestic electric or gas oven.

Plus particulièrement, la présente invention concerne une porte destinée à équiper un four électrique à pyrolyse, dans lequel la température à l'intérieur de l'enceinte de cuisson peut atteindre 500°C lors des cycles de pyrolyse.More particularly, the present invention relates to a door for equipping an electric pyrolysis furnace, wherein the temperature inside the cooking chamber can reach 500 ° C during pyrolysis cycles.

Il est connu d'utiliser des portes pour enceinte de cuisson comportant plusieurs panneaux, généralement vitrés, montés parallèlement les uns aux autres sur un cadre de porte. En particulier, une porte de cuisson comporte généralement un panneau intérieur destiné à obturer l'enceinte de cuisson, un panneau extérieur, apparent sur la façade de l'appareil de cuisson et un ou plusieurs panneaux intermédiaires disposés dans le cadre de porte entre le panneau extérieur et le panneau intérieur.It is known to use cooking chamber doors comprising several panels, generally glazed, mounted parallel to each other on a door frame. In particular, a cooking door generally comprises an inner panel for closing the cooking chamber, an outer panel, visible on the front of the cooking appliance and one or more intermediate panels arranged in the door frame between the panel exterior and interior panel.

Les panneaux intermédiaires permettent, en créant des lames d'air isolantes, et grâce à une ventilation créant des flux d'air de refroidissement circulant entre les différents panneaux de la porte, de limiter la montée en température de la porte, notamment au niveau du panneau extérieur.The intermediate panels allow, by creating insulating air slats, and through ventilation creating cooling air flows circulating between the different panels of the door, to limit the rise in temperature of the door, particularly at the level of the door. outer panel.

On connaît ainsi dans le document EP 1 291 583 une porte pour enceinte de cuisson dans laquelle le cadre de porte est muni au quatre angles d'un élément de fixation, solidaire du cadre de porte. Cet élément de fixation est adapté au montage de manière amovible d'un panneau intermédiaire de porte. A cet égard, chaque élément de fixation comporte une butée et une patte de rappel élastique permettant de maintenir par pincement un panneau intermédiaire vitré à ses angles, entre la butée et l'élément de rappel élastique.We thus know in the document EP 1 291 583 a door for a cooking chamber in which the door frame is provided at the four corners with a fastening element secured to the door frame. This fastener is adapted to removably mount an intermediate door panel. In this respect, each fastening element comprises a stop and an elastic return lug making it possible to pinch an intermediate glazed panel at its corners, between the abutment and the elastic return element.

Le démontage du panneau intermédiaire, notamment pour son nettoyage, peut être réalisé en soulevant ce panneau et en écartant les éléments de rappel élastique de chaque élément de fixation, aux quatre coins du cadre de porte.The disassembly of the intermediate panel, especially for cleaning, can be achieved by lifting the panel and by removing the resilient return elements of each fastener at the four corners of the door frame.

Le démontage d'un panneau intermédiaire maintenu ainsi à ses quatre coins par des éléments élastiques solidaires du cadre de la porte est relativement compliqué à mettre en oeuvre, l'utilisateur devant à la fois soulever le panneau intermédiaire et agir sur les différents éléments de fixation disposés aux quatre coins pour libérer le panneau de ses éléments de fixation.The disassembly of an intermediate panel thus held at its four corners by resilient elements integral with the door frame is relatively complicated to implement, the user having to both lift the intermediate panel and act on the various fixing elements arranged at the four corners to release the panel of its fasteners.

On connaît également dans le document DE 197 38506 une porte d'appareil de cuisson à plusieurs panneaux vitrés, dans laquelle un panneau intermédiaire est muni d'éléments de cadre s'étendant sur les bords du panneau intermédiaire et comportant des ailes ou surépaisseurs destinées à venir en contact avec les panneaux extérieur et intérieur de la porte.It is also known in the document DE 197 38506 a multi-glazed cooking appliance door, in which an intermediate panel is provided with frame members extending on the edges of the intermediate panel and having wings or thickenings intended to come into contact with the outer and inner panels Door.

La vitre intermédiaire peut être enlevée de la structure de la porte avec ses éléments de cadre. Ces éléments de cadre peuvent être appliqués par injection, directement sur le pourtour de la vitre intermédiaire, ou encore être préfabriqués puis montés et fixés par un adhésif sur les bords de la vitre intermédiaire.The intermediate pane can be removed from the door structure with its frame elements. These frame members can be applied by injection, directly on the periphery of the intermediate window, or be prefabricated and then mounted and fixed by an adhesive on the edges of the intermediate window.

Ces éléments de cadre étant solidaires de la vitre intermédiaire, le nettoyage de la vitre intermédiaire ne peut être parfait dans ces zones.These frame members being integral with the intermediate window, the cleaning of the intermediate window can not be perfect in these areas.

Une autre porte d'appareil de cuisson est décrit dans le document US 2005/0028805 A1 .Another cooking appliance door is described in the document US 2005/0028805 A1 .

La présente invention a pour but de résoudre les inconvénients précités et de proposer une porte pour enceinte de cuisson permettant notamment un montage et démontage simplifiés d'une vitre intermédiaire en vue de faciliter son nettoyage.The present invention aims to solve the aforementioned drawbacks and to provide a door for a cooking chamber allowing in particular a simplified assembly and disassembly of an intermediate window to facilitate cleaning.

A cet effet, la présente invention concerne une porte pour enceinte de cuisson comportant un panneau extérieur, un cadre de porte solidaire du panneau extérieur, un panneau intérieur monté de manière amovible sur ledit cadre de porte et adapté à obturer l'enceinte de cuisson, et au moins un panneau intermédiaire monté de manière amovible dans ledit cadre de porte entre le panneau extérieur et le panneau intérieur, des moyens de maintien étant adaptés à maintenir ledit au moins un panneau intermédiaire dans le cadre de porte.For this purpose, the present invention relates to a cooking chamber door comprising an outer panel, a door frame secured to the outer panel, an inner panel removably mounted on said door frame and adapted to close the cooking chamber, and at least one intermediate panel removably mounted in said door frame between the outer panel and the inner panel, holding means being adapted to hold said at least one intermediate panel in the door frame.

Selon l'invention, lesdits moyens de maintien comprennent au moins deux éléments de maintien en forme de coin adaptés d'une part à être logés de manière amovible respectivement dans deux angles du cadre de porte et d'autre part à être montés de manière amovible respectivement à deux angles dudit panneau intermédiaire.According to the invention, said holding means comprise at least two wedge-shaped holding elements adapted on the one hand to be removably housed respectively in two corners of the door frame and on the other hand to be removably mounted. respectively at two angles of said intermediate panel.

Ainsi, les éléments de fixation sont limités aux coins du panneau intermédiaire et sont détachables à la fois du cadre de porte et du panneau intermédiaire.Thus, the fasteners are limited to the corners of the intermediate panel and are detachable from both the door frame and the intermediate panel.

Le démontage et montage du panneau intermédiaire dans le cadre de porte peuvent être réalisés facilement dès lors que les coins sont déplacés avec le panneau intermédiaire, sans requérir d'intervention de l'utilisateur sur ces coins de fixation pour extraire le panneau.Disassembly and mounting of the intermediate panel in the door frame can be achieved easily when the corners are moved with the intermediate panel, without requiring user intervention on these fixing corners to extract the panel.

Par ailleurs, ces coins peuvent être montés et démontés facilement aux angles du panneau intermédiaire permettant un nettoyage complet de la vitre avant son remontage dans la porte pour enceinte de cuisson.Furthermore, these corners can be mounted and removed easily at the corners of the intermediate panel for a complete cleaning of the window before reassembly in the cooking chamber door.

En outre, la forme en coin permet de garantir le maintien en position des éléments de maintien sur le panneau intermédiaire lors de sa manipulation, même en cas de forces de frottement exercées entre le cadre de porte et ces éléments de maintien au montage ou au démontage du panneau intermédiaire, et ceci bien que ces éléments de maintien soient détachables pour faciliter le nettoyage du panneau intermédiaire.In addition, the wedge shape makes it possible to ensure that the holding elements are held in position on the intermediate panel during its handling, even in the case of frictional forces exerted between the door frame and these holding elements during assembly or disassembly. of the intermediate panel, and this although these holding elements are detachable to facilitate the cleaning of the intermediate panel.

Enfin, grâce au montage amovible des éléments de maintien à la fois dans le cadre de porte et sur les angles du ou des panneaux intermédiaires, ces éléments de maintien permettent d'absorber et de résister aux déformations du cadre et des panneaux intermédiaires, notamment sous l'effet de la chaleur dégagée au niveau de l'enceinte de cuisson.Finally, thanks to the removable mounting of the holding elements both in the door frame and on the corners of the intermediate panel or panels, these holding elements allow to absorb and withstand the deformations of the frame and intermediate panels, especially under the effect of the heat released at the cooking chamber.

En pratique, chaque élément de maintien en forme de coin est constitué d'une pièce de section transversale en forme de triangle rectangle, particulièrement bien adaptée à un angle du cadre de porte.In practice, each wedge-shaped holding element consists of a cross-section piece in the shape of a right-angled triangle, particularly well adapted to an angle of the door frame.

Dans un mode de réalisation de l'invention, chaque élément de maintien comporte au moins une encoche intérieure adaptée à loger un angle d'un panneau intermédiaire.In one embodiment of the invention, each holding element comprises at least one inner slot adapted to house an angle of an intermediate panel.

De préférence, la hauteur de cette encoche est inférieure de quelques dixièmes de millimètres à l'épaisseur de l'angle du panneau intermédiaire. L'introduction en force de l'angle d'un panneau intermédiaire dans l'élément de maintien permet par la suite d'assurer un montage fiable de cet élément de maintien sur le panneau intermédiaire. En particulier, l'élément de maintien n'est pas déplacé en cas de choc, notamment lors du transport de l'appareil de cuisson.Preferably, the height of this notch is a few tenths of a millimeter less than the thickness of the angle of the intermediate panel. The introduction in force of the angle of an intermediate panel in the holding member allows thereafter to ensure a reliable mounting of this holding member on the intermediate panel. In particular, the holding member is not moved in case of shock, especially during the transport of the cooking appliance.

Le montage serré du panneau intermédiaire dans les coins permet en outre d'éviter la mise en vibration du panneau intermédiaire.The tight fitting of the intermediate panel in the corners also makes it possible to avoid the vibration of the intermediate panel.

Selon un mode de réalisation particulier de l'invention, chaque élément de maintien comporte au moins deux encoches intérieures disposées dans deux plans parallèles, permettant de maintenir ensemble deux panneaux intermédiaires disposés parallèlement l'un à l'autre.According to a particular embodiment of the invention, each holding element comprises at least two internal notches arranged in two parallel planes, for holding together two intermediate panels arranged parallel to each other.

Ces panneaux intermédiaires peuvent ainsi être montés et démontés ensemble dans le cadre de porte.These intermediate panels can be mounted and dismounted together in the door frame.

Selon un autre mode de réalisation, chaque élément de maintien comporte au moins une encoche intérieure disposée dans un plan transversal incliné par rapport à une face d'extrémité adaptée à venir en contact avec le panneau extérieur ou le panneau intérieur.According to another embodiment, each holding element comprises at least one inner slot disposed in a transverse plane inclined with respect to an end face adapted to come into contact with the outer panel or the inner panel.

Cet élément de maintien permet de disposer un panneau intermédiaire dans un plan incliné par rapport au panneau extérieur ou au panneau intérieur de la porte.This holding member provides an intermediate panel in a plane inclined relative to the outer panel or the inner panel of the door.

Cette disposition permet notamment d'améliorer le refroidissement de la porte par circulation d'un flux d'air.This arrangement makes it possible in particular to improve the cooling of the door by circulating an air flow.

En pratique, les éléments de maintien sont en silicone, de manière à réduire le transfert thermique entre les différents panneaux de la porte d'enceinte de cuisson.In practice, the holding elements are made of silicone, so as to reduce the heat transfer between the various panels of the cooking chamber door.

Les éléments de maintien sont comprimés entre le panneau extérieur et le panneau intérieur de la porte ou entre le cadre de porte et le panneau intérieur afin de garantir un montage serré et sans jeu fonctionnel de l'assemblage constitué des panneaux intermédiaires et des panneaux intérieur et extérieur de la porte.The holding members are compressed between the outer panel and the interior panel of the door or between the door frame and the inner panel to ensure a tight fit without any functional play of the assembly consisting of the intermediate panels and the interior panels and outside the door.

Selon un mode de réalisation pratique de l'invention, le cadre de porte comporte également un décrochement formant un espace de préhension d'un bord du ou des panneaux intermédiaires, permettant à l'utilisateur de soulever le ou les panneaux intermédiaires lors du démontage.According to a practical embodiment of the invention, the door frame also comprises a recess forming a gripping space of an edge of the intermediate panel or panels, allowing the user to lift the intermediate panel or panels during disassembly.

La présente invention concerne également un four de cuisson domestique, notamment un four à pyrolyse, comprenant une porte pour enceinte de cuisson conforme à l'invention.The present invention also relates to a domestic cooking oven, in particular a pyrolysis oven, comprising a door for a cooking chamber according to the invention.

On va décrire tout d'abord en référence aux figures 1 et 2 une porte pour enceinte de cuisson conforme à un mode de réalisation de l'invention.We will first describe with reference to figures 1 and 2 a door for a cooking chamber according to an embodiment of the invention.

Typiquement, cette porte pour enceinte de cuisson peut équiper un four de cuisson domestique, et par exemple un four de cuisson électrique adapté à mettre en oeuvre un cycle de pyrolyse pour le nettoyage de l'enceinte de cuisson. Dans ce cas, la température à l'intérieur de l'enceinte de cuisson peut atteindre 500°C.Typically, this door for cooking chamber can equip a domestic cooking oven, and for example an electric cooking oven adapted to implement a pyrolysis cycle for cleaning the cooking chamber. In this case, the temperature inside the cooking chamber can reach 500 ° C.

Pour des raisons de sécurité, ce type d'enceinte de cuisson est équipé d'une porte, dite porte froide, dont la structure particulière permet de limiter la température en façade, au niveau d'un panneau extérieur de la porte.For safety reasons, this type of cooking chamber is equipped with a door, called cold door, the particular structure of which limits the temperature on the front, at an outer panel of the door.

Typiquement, lors d'un cycle de pyrolyse, la température du panneau extérieur peut rester inférieure à 50-55°C.Typically, during a pyrolysis cycle, the temperature of the outer panel may remain below 50-55 ° C.

Un exemple de réalisation d'une porte 10 pour enceinte de cuisson est illustré en détail à la figure 1.An exemplary embodiment of a door 10 for a cooking chamber is illustrated in detail in FIG. figure 1 .

La porte 10 comporte un panneau extérieur 11 destiné à venir en façade de l'appareil. Ce panneau extérieur 11 forme généralement un décor et est constitué d'un panneau vitré sur l'intégralité de sa surface ou au moins sur la majeure partie de sa surface pour permettre de visualiser l'intérieur de l'enceinte de cuisson.The door 10 has an outer panel 11 intended to come to the front of the device. This outer panel 11 generally forms a decor and consists of a glazed panel on the entire surface or at least on most of its surface to allow viewing of the interior of the cooking chamber.

Ce panneau extérieur 11 est associé à un cadre de porte 12. Ce cadre de porte 12 est monté de façon solidaire sur le panneau extérieur 11 par l'intermédiaire d'une traverse 13 et de différents éléments de fixation du type vis de fixation qui ne sont pas décrits ici en détail.This outer panel 11 is associated with a door frame 12. This door frame 12 is integrally mounted on the outer panel 11 by means of a cross member 13 and various fixing elements of the fixing screw type which do not are not described here in detail.

Dans ce mode de réalisation, le cadre de porte 12 est rectangulaire et est destiné à loger un panneau intérieur 14. Ce panneau intérieur 14 est monté de manière amovible dans le cadre de porte 12 comme cela va être décrit ultérieurement. Ce panneau intérieur 14 est destiné à venir en regard avec l'enceinte de cuisson et à obturer celle-ci.In this embodiment, the door frame 12 is rectangular and is intended to house an inner panel 14. This inner panel 14 is removably mounted in the door frame 12 as will be described later. This inner panel 14 is intended to come opposite the cooking chamber and to close it.

Dans ce mode de réalisation, entre le panneau extérieur 11 et le panneau intérieur 14, deux panneaux intermédiaires 15, 16 sont disposés dans le cadre 12.In this embodiment, between the outer panel 11 and the inner panel 14, two intermediate panels 15, 16 are arranged in the frame 12.

Bien entendu, un seul panneau intermédiaire ou un nombre supérieur à deux pourrait être prévu dans la porte 10.Of course, only one intermediate panel or a number greater than two could be provided in the door 10.

Les panneaux 14, 15, 16 comportent des surfaces vitrées permettant à l'utilisateur d'observer au travers de la porte 10 le contenu de l'enceinte de cuisson.The panels 14, 15, 16 have glazed surfaces allowing the user to observe through the door 10 the contents of the cooking chamber.

Dans ce mode de réalisation, les panneaux 14, 15, 16 sont constitués de panneaux vitrés.In this embodiment, the panels 14, 15, 16 are made of glazed panels.

Les panneaux intermédiaires 15, 16 sont montés dans le cadre de porte grâce à des moyens de maintien 17 qui seront décrits ultérieurement.The intermediate panels 15, 16 are mounted in the door frame by means of holding means 17 which will be described later.

La figure 2 illustre le montage des panneaux intermédiaires 15, 16 dans le cadre 12 de la porte 10.The figure 2 illustrates the mounting of the intermediate panels 15, 16 in the frame 12 of the door 10.

Au-dessus de cet assemblage illustré à la figure 2, le panneau intérieur 14 peut être monté de manière amovible et inséré dans une rainure formée par une barrette longitudinale 18 solidaire d'un bord du cadre 12.Above this assembly illustrated at figure 2 , the inner panel 14 can be removably mounted and inserted into a groove formed by a longitudinal bar 18 integral with an edge of the frame 12.

Dans ce mode de réalisation, la barrette longitudinale 18 est disposée le long d'un bord supérieur 10a de la porte 10. Ce bord supérieur 10a de la porte 10 est destiné à être placé horizontalement et en partie haute de l'appareil de cuisson lorsque la porte obture l'enceinte de cuisson.In this embodiment, the longitudinal bar 18 is disposed along an upper edge 10a of the door 10. This upper edge 10a of the door 10 is intended to be placed horizontally and in the upper part of the cooking appliance when the door closes the cooking chamber.

Le montage du panneau intérieur 14 dans le cadre est réalisé dans la barrette 18 et au moyen d'un clip 19 destiné à maintenir par pincement le panneau intérieur 14 dans le cadre de porte 12 au niveau du bord inférieur 10b de la porte 10.The mounting of the inner panel 14 in the frame is carried out in the bar 18 and by means of a clip 19 intended to pinch the inner panel 14 in the door frame 12 at the lower edge 10b of the door 10.

Comme bien illustré sur la figure 2, le cadre 12 comporte en outre un décrochement 20 formant un espace de préhension au niveau du bord des panneaux intermédiaires 15, 16.As well illustrated on the figure 2 , the frame 12 further comprises a recess 20 forming a gripping space at the edge of the intermediate panels 15, 16.

Ce décrochement 20 permet à l'utilisateur de passer la main pour soulever les panneaux intermédiaires 15, 16 lors du démontage de ces panneaux.This recess 20 allows the user to pass the hand to lift the intermediate panels 15, 16 during disassembly of these panels.

Afin de limiter l'élévation en température de la porte, celle-ci est généralement associée à un système de ventilation adapté à aspirer de l'air au travers de la porte par aspiration forcée ou effet Venturi, entre les différents panneaux 11, 14, 15, 16 juxtaposés.In order to limit the rise in temperature of the door, it is generally associated with a ventilation system adapted to draw air through the door by forced suction or Venturi effect, between the various panels 11, 14, 15, 16 juxtaposed.

Pour permettre la circulation du flux d'air, le cadre de porte 12 comprend des fentes 12a, 12b au niveau respectivement du bord supérieur 10a et du bord inférieur 10b de la porte 10.To allow the circulation of the air flow, the door frame 12 comprises slots 12a, 12b at respectively the upper edge 10a and the lower edge 10b of the door 10.

En partie haute de la porte, un profilé 21 est monté de manière adjacente au cadre 12, et parallèlement à une fente de sortie d'air 12a. Ce profilé 21 comporte des ouies 22 permettant la sortie de l'air en partie haute de la porte 10.In the upper part of the door, a profile 21 is mounted adjacent to the frame 12, and parallel to an air outlet slot 12a. This section 21 comprises louvers 22 allowing the air outlet at the top of the door 10.

On va décrire à présent en référence aux figures 3 à 6 un premier mode de réalisation des moyens de maintien des panneaux intermédiaires 15, 16 dans la porte 10.We will now describe with reference to Figures 3 to 6 a first embodiment of the means for holding the intermediate panels 15, 16 in the door 10.

Dans ce premier mode de réalisation, les panneaux intermédiaires 15, 16 sont disposés parallèlement au panneau intérieur 14 et au panneau extérieur 11.In this first embodiment, the intermediate panels 15, 16 are arranged parallel to the inner panel 14 and to the outer panel 11.

Les éléments de maintien 17 sont en forme de coin et destinés à être montés aux angles des panneaux intermédiaires 15, 16.The holding elements 17 are wedge-shaped and intended to be mounted at the corners of the intermediate panels 15, 16.

Dans ce mode de réalisation, les éléments de maintien sont au nombre de quatre et destinés à être logés respectivement aux quatre angles du cadre de porte 12. Ils sont ainsi montés également aux quatre angles des panneaux intermédiaires 15, 16.In this embodiment, the holding elements are four in number and intended to be housed respectively at the four corners of the door frame 12. They are thus also mounted at the four corners of the intermediate panels 15, 16.

Bien entendu, seul deux éléments de maintien 17, logés à deux angles diamétralement opposés du cadre de porte 12, pourraient également être utilisés.Of course, only two holding members 17, housed at two diametrically opposite angles of the door frame 12, could also be used.

Comme bien illustré à la figure 4, chaque élément de maintien 17 en forme de coin est constitué d'une pièce de section transversale en forme de triangle rectangle (voir notamment figure 6).As well illustrated at the figure 4 each wedge-shaped holding element 17 consists of a cross-sectional piece in the shape of a right-angled triangle (see in particular figure 6 ).

Chaque élément de maintien 17 comporte ainsi deux faces perpendiculaires 17a et une face en pan coupé 17d.Each holding element 17 thus comprises two perpendicular faces 17a and a cutaway face 17d.

Comme illustré à la figure 3, chaque élément de maintien 17 est monté dans un angle du cadre de porte 12 de telle sorte que les deux faces perpendiculaires 17a viennent en appui contre les côtés 12b du cadre de porte.As illustrated in figure 3 each holding member 17 is mounted at an angle of the door frame 12 so that the two perpendicular faces 17a bear against the sides 12b of the door frame.

Chaque élément de maintien 17 est adapté à être logé de manière amovible aux angles du cadre de porte 12.Each holding element 17 is adapted to be housed removably at the corners of the door frame 12.

Dans ce mode de réalisation, le cadre de porte 12 comporte aux quatre angles des formes embouties 12c, telles qu'illustrées à la figure 3, adaptées à loger respectivement chaque élément en forme de coin 17.In this embodiment, the door frame 12 has at the four corners stamped shapes 12c, as illustrated in FIG. figure 3 adapted to respectively accommodate each wedge member 17.

Dans ce mode de réalisation, chaque forme emboutie 12c s'étend à partir du cadre de porte 12 en direction du panneau extérieur 11 de la porte. Ainsi, lorsque l'une des faces d'extrémité 17b de l'élément de maintien 17 est en contact avec la forme emboutie 12c, l'autre face d'extrémité 17c vient en contact avec le panneau intérieur 14 lorsque celui-ci est monté dans le cadre de porte 12.In this embodiment, each stamped shape 12c extends from the door frame 12 toward the outer panel 11 of the door. Thus, when one of the end faces 17b of the holding member 17 is in contact with the pressed form 12c, the other end face 17c comes into contact with the inner panel 14 when the latter is mounted in the door frame 12.

Bien entendu, un montage inverse pourrait être envisagé, l'élément de maintien 17 venant alors en contact au niveau de ses faces d'extrémité respectivement avec une forme emboutie solidaire du cadre 12 et le panneau extérieur 11 de la porte.Of course, a reverse assembly could be envisaged, the holding element 17 then coming into contact at its end faces respectively with a stamped form secured to the frame 12 and the outer panel 11 of the door.

De préférence, la hauteur des éléments de maintien 17 est telle que ces éléments de maintien 17 sont comprimés entre le cadre de porte 12 et le panneau intérieur 14, ou encore entre le cadre de porte 12 et le panneau extérieur 11 dans un montage alternatif.Preferably, the height of the holding elements 17 is such that these holding elements 17 are compressed between the door frame 12 and the inner panel 14, or between the door frame 12 and the outer panel 11 in an alternative arrangement.

L'utilisation d'un logement en forme d'emboutie 12c solidaire du cadre permet de ménager un faible espace entre la forme emboutie 12c et le panneau extérieur 11 de la porte et d'éviter ainsi une conduction thermique directe entre le panneau extérieur et le panneau intérieur au travers de chaque élément de maintien 17.The use of a stamped housing 12c integral with the frame allows to provide a small space between the stamped form 12c and the outer panel 11 of the door and thus avoid a direct thermal conduction between the outer panel and the inner panel through each holding member 17.

Bien entendu, d'autres types de montage des éléments de maintien pourraient être prévus, et notamment sans l'utilisation d'une forme emboutie au niveau de chaque coin du cadre de porte 12. Ainsi, les éléments de maintien 17 peuvent être montés directement entre le panneau extérieur 11 et le panneau intérieur 14 et maintenus en compression entre ces deux panneaux 11, 14.Of course, other types of mounting of the holding elements could be provided, and in particular without the use of a stamped shape at each corner of the door frame 12. Thus, the holding elements 17 can be mounted directly between the outer panel 11 and the inner panel 14 and kept in compression between these two panels 11, 14.

De préférence, ces éléments de maintien 17 sont en silicone, résistant à une température d'environ 250°C. Le matériau utilisé pour la réalisation de ces éléments de maintien 17 doit également présenter une dureté suffisante, et par exemple comprise entre 50 et 70 Shore, et de préférence sensiblement égale à 60 Shore, afin d'éviter l'écrasement des éléments de maintien maintenus en compression dans le cadre de porte 12.Preferably, these holding elements 17 are made of silicone, resistant to a temperature of about 250 ° C. The material used for the production of these holding elements 17 must also have a sufficient hardness, for example between 50 and 70 Shore, and preferably substantially equal to 60 Shore, in order to avoid the crushing of the holding elements maintained. in compression in the door frame 12.

Grâce à ce montage en compression de chaque élément de maintien 17 dans le cadre de porte, il est possible de supprimer les jeux fonctionnels lors de l'assemblage des panneaux dans la porte.Thanks to this compression mounting of each holding element 17 in the door frame, it is possible to eliminate the functional gaps during assembly of the panels in the door.

L'utilisation d'un matériau tel que le silicone permet de réduire en outre le transfert thermique entre les différents panneaux montés au travers de l'élément de maintien 17. Bien entendu, l'élément de maintien pourrait également être réalisé dans un matériau plastique présentant des caractéristiques similaires en terme de dureté et de transfert thermique.The use of a material such as silicone also makes it possible to reduce the heat transfer between the various panels mounted through the holding element 17. Of course, the holding element could also be made from a plastic material having similar characteristics in terms of hardness and heat transfer.

Outre le montage amovible de chaque élément de maintien 17 aux quatre coins de cadre de porte 12, chaque élément de maintien 17 est également adapté à être monté de manière amovible aux angles des panneaux intermédiaires 15, 16.In addition to the detachable mounting of each holding element 17 to the four door frame corners 12, each holding element 17 is also adapted to be removably mounted at the corners of the intermediate panels 15, 16.

Dans ce mode de réalisation dans lequel deux panneaux intermédiaires 15, 16 sont montés entre le panneau extérieur 11 et le panneau intérieur 14 de la porte, chaque élément de maintien 17 tel que bien illustré à la figure 4 comporte, débouchant sur la face en pan coupé 17d, deux encoches intérieures 23 adaptées respectivement à loger un angle de chaque panneaux intermédiaires 15, 16.In this embodiment in which two intermediate panels 15, 16 are mounted between the outer panel 11 and the inner panel 14 of the door, each holding element 17 as well illustrated in FIG. figure 4 comprises, opening on the cutaway face 17d, two internal notches 23 respectively adapted to accommodate an angle of each intermediate panels 15, 16.

Bien entendu, si la structure de porte ne comportait qu'un seul panneau intermédiaire, une seule encoche intérieure pourrait être prévue dans l'élément de maintien 17.Of course, if the door structure had only one intermediate panel, only one interior notch could be provided in the holding member 17.

Afin d'assurer le maintien en position de chaque panneaux intermédiaires, la hauteur d de chaque encoche intérieure 23 (voir notamment figure 5) est inférieure de quelques dizièmes de millimètre à l'épaisseur de l'angle de chaque panneaux intermédiaires 15, 16.In order to maintain the position of each intermediate panel, the height d of each internal notch 23 (see in particular figure 5 ) is a few tenths of a millimeter less than the thickness of the angle of each intermediate panel 15, 16.

En pratique, chaque panneaux intermédiaires 15, 16 peut présenter une épaisseur égale par exemple à 3 mm, la hauteur d de chaque encoche 23 des éléments de maintien 17 pouvant être comprise entre 2,5 et 2,8 mm.In practice, each intermediate panel 15, 16 may have a thickness equal for example to 3 mm, the height d of each notch 23 of the holding elements 17 may be between 2.5 and 2.8 mm.

Afin d'assurer le montage parallèle des panneaux intermédiaires 15, 16 et des panneaux extérieur 11 et intérieur 14, chaque élément de maintien 17 comporte des encoches intérieures 23 disposées dans deux plans parallèles confondus avec la section transversale de chaque élément de maintien 17. Comme bien illustré à la figure 6, chaque encoche 23 forme ainsi une encoche en forme de coin dans un plan transversal de l'élément de maintien 17.In order to ensure the parallel assembly of the intermediate panels 15, 16 and the outer 11 and inner 14 panels, each holding element 17 has internal notches 23 arranged in two parallel planes coinciding with the cross section of each holding element 17. As well illustrated at the figure 6 each notch 23 thus forms a wedge-shaped notch in a transverse plane of the holding element 17.

Dès lors que les faces d'extrémité 17b, 17c de chaque éléments de maintien 17 sont parallèles, et qu'au moins l'une de ces faces d'extrémités est adaptée à venir en contact avec le panneau intérieur 14 dans ce mode de réalisation, ou encore le panneau extérieur dans un mode alternatif, les encoches 23 s'étendent également dans un plan parallèle au panneau extérieur 11 et au panneau intérieur 14 de la porte.Since the end faces 17b, 17c of each holding element 17 are parallel, and at least one of these end faces is adapted to come into contact with the inner panel 14 in this embodiment. or the outer panel in an alternative mode, the notches 23 also extend in a plane parallel to the outer panel 11 and the inner panel 14 of the door.

Grâce à ce montage dans deux encoches 23 de chaque élément de maintien 17 des panneaux intermédiaires 15, 16, ces derniers peuvent être montés et démontés ensemble, grâce à une seule manipulation de l'utilisateur, dans le cadre de porte 12. Cette opération est de nature à faciliter le démontage de la porte en vue de son nettoyage.Thanks to this mounting in two notches 23 of each holding element 17 of the intermediate panels 15, 16, the latter can be assembled and disassembled together, thanks to a single manipulation of the user, in the door frame 12. This operation is to facilitate the dismantling of the door for cleaning.

En outre, le montage amovible de chaque éléments de maintien 17 aux quatre coins des panneaux intermédiaires 15, 16 permet ensuite à l'utilisateur d'ôter ces éléments de maintien et de séparer ainsi les panneaux intermédiaires afin de permettre un nettoyage séparé de chacun de ces panneaux intermédiaires 15, 16.In addition, the removable assembly of each holding element 17 at the four corners of the intermediate panels 15, 16 then allows the user to remove these holding elements and thus separate the intermediate panels to allow a separate cleaning of each of these intermediate panels 15, 16.

Le montage amovible des éléments de maintien 17 à la fois dans le cadre de porte 12 et sur les panneaux intermédiaires 15, 16, ainsi qu'au niveau du panneau intérieur 14, permet à ces éléments de maintien d'absorber les dilatations des différents matériaux en présence, dues notamment à la montée en température de la porte.Removable mounting of the holding members 17 in both the door frame 12 and the intermediate panels 15, 16, as well as at the inner panel 14, allows these holding elements to absorb the expansions of the different materials. in the presence, due in particular to the rise in temperature of the door.

Un second mode de réalisation de l'invention a également été illustré dans les figures 7 à 13.A second embodiment of the invention has also been illustrated in the Figures 7 to 13 .

Les éléments identiques au premier mode de réalisation ne seront pas redécrits ici et portent les mêmes références numériques.The elements identical to the first embodiment will not be redescribed here and bear the same numerical references.

En particulier, dans ce mode de réalisation deux panneaux intermédiaires 15, 16 sont également disposés entre deux panneaux extérieur 11 et intérieur 14 d'une porte 10. Toutefois, à la différence du premier mode de réalisation décrit précédemment, les panneaux intermédiaires 15, 16 sont disposés dans des plans inclinés par rapport aux panneaux intérieur et extérieur montés parallèlement.In particular, in this embodiment two intermediate panels 15, 16 are also arranged between two outer panels 11 and inner 14 of a door 10. However, unlike the first embodiment described above, the intermediate panels 15, 16 are arranged in inclined planes with respect to the inner and outer panels mounted parallel.

Bien entendu, seul un unique panneau intermédiaire pourrait s'étendre dans un plan incliné par rapport au panneau extérieur et au panneau intérieur.Of course, only a single intermediate panel could extend in a plane inclined relative to the outer panel and the inner panel.

Dans ce mode de réalisation tel que bien illustré à la figure 7, les deux panneaux intermédiaires 15, 16 s'étendent respectivement dans deux plans inclinés l'un par rapport à l'autre et également par rapport au panneau extérieur et au panneau intérieur.In this embodiment as well illustrated in the figure 7 the two intermediate panels 15, 16 extend respectively in two inclined planes relative to each other and also with respect to the outer panel and the inner panel.

La disposition inclinée de ces panneaux intermédiaires 15, 16 à l'intérieur de la porte 10 permet de favoriser la circulation de l'air de refroidissement dans cette porte et ainsi de diminuer la montée en température à l'intérieur de la porte.The inclined disposition of these intermediate panels 15, 16 inside the door 10 makes it possible to promote the circulation of the cooling air in this door and thus to reduce the rise in temperature inside the door.

Comme bien illustré par les flèches sur le figure 7, cette porte destinée à obturer une enceinte de cuisson est associée à un système de ventilation adapté à établir un flux d'air (flèche F) qui circule d'un bord inférieur 10b à un bord supérieur 10a de la porte 10.As well illustrated by the arrows on the figure 7 this door for closing a cooking chamber is associated with a ventilation system adapted to establish an air flow (arrow F) which flows from a lower edge 10b to an upper edge 10a of the door 10.

La porte 10 comprend un premier panneau intermédiaire 15 disposé directement en regard du panneau extérieur 11. La distance séparant ce premier panneau intermédiaire 15 du panneau extérieur 11 à proximité du bord inférieur 10b de la porte est inférieure à la distance séparant ce premier panneau intermédiaire 15 du panneau extérieur 11 à proximité du bord supérieur 10a de la porte.The door 10 comprises a first intermediate panel 15 disposed directly opposite the outer panel 11. The distance separating said first intermediate panel 15 from the outer panel 11 near the lower edge 10b of the door is less than the distance separating said first intermediate panel 15 the outer panel 11 near the upper edge 10a of the door.

Dans ce mode de réalisation, la porte comprend en outre un second panneau intermédiaire 16 disposé entre le premier panneau intermédiaire 15 et le panneau intérieur 14 de la porte 10. La distance séparant le second panneau intermédiaire 16 du panneau intérieur 14 à proximité du bord inférieur 10b de la porte 10 est inférieure à la distance séparant le second panneau intermédiaire 16 du panneau intérieur 14 à proximité du bord supérieur 10a de la porte 10.In this embodiment, the door further comprises a second intermediate panel 16 disposed between the first intermediate panel 15 and the inner panel 14 of the door 10. The distance separating the second intermediate panel 16 from the inner panel 14 near the lower edge 10b of the door 10 is smaller than the distance separating the second intermediate panel 16 from the inner panel 14 near the upper edge 10a of the door 10.

Ainsi, la distance séparant chaque panneaux intermédiaires 15, 16 à proximité du bord supérieur 10a de la porte est inférieure à la distance séparant les panneaux intermédiaires 15, 16 à proximité du bord inférieur 10b de la porte 10.Thus, the distance between each intermediate panel 15, 16 near the upper edge 10a of the door is less than the distance between the intermediate panels 15, 16 near the lower edge 10b of the door 10.

A titre d'exemples non limitatifs, lorsque la distance séparant les panneaux intérieur et extérieur est de l'ordre de 26 mm, la distance séparant les panneaux intermédiaires 15, 16 est par exemple égale à 8 mm à proximité du bord supérieur 10a de la porte et égale à 10 mm à proximité du bord inférieur 10b de la porte.As non-limiting examples, when the distance separating the inner and outer panels is of the order of 26 mm, the distance separating the intermediate panels 15, 16 is for example equal to 8 mm near the upper edge 10 a of the door and equal to 10 mm near the lower edge 10b of the door.

Par ailleurs, le premier panneau intermédiaire 15 peut être disposé à une distance du panneau extérieur 11 égale sensiblement à 5 mm au niveau du bord inférieur 10b de la porte 10 et sensiblement égale à 7 mm au niveau du bord supérieur 10a de la porte 10. De même, le second panneau intermédiaire 16 peut être disposé à une distance d'environ 3 mm du panneau intérieur 14 au niveau du bord inférieur 10b de la porte 10 et à une distance d'environ 5 mm au niveau du bord supérieur 10a de la porte 10.Moreover, the first intermediate panel 15 may be disposed at a distance from the outer panel 11 substantially equal to 5 mm at the lower edge 10b of the door 10 and substantially equal to 7 mm at the level of the upper edge 10a of the door 10. Similarly, the second intermediate panel 16 may be disposed at a distance of about 3 mm from the inner panel 14 at the lower edge 10b of the door 10 and at a distance of about 5 mm at the upper edge 10a of the door 10.

Bien entendu, ces valeurs de distance ne sont nullement limitatives et ne sont destinées qu'à illustrer un mode de réalisation de la présente invention.Of course, these distance values are in no way limiting and are only intended to illustrate an embodiment of the present invention.

Le flux d'air circulant à l'intérieur de la porte 11 est adapté à refroidir les différents panneaux disposés en vis-à-vis et à limiter ainsi la montée en température notamment au niveau du panneau extérieur 11 directement accessible à un utilisateur.The flow of air flowing inside the door 11 is adapted to cool the different panels arranged vis-à-vis and thereby limit the rise in temperature especially at the outer panel 11 directly accessible to a user.

De préférence, le flux d'air établi par le système de ventilation est adapté à circuler uniquement entre le panneau extérieur 11 et le premier panneau intermédiaire 15, ainsi qu'entre le premier panneau intermédiaire 15 et le second panneau intermédiaire 16.Preferably, the airflow established by the ventilation system is adapted to circulate only between the outer panel 11 and the first intermediate panel 15, as well as between the first intermediate panel 15 and the second intermediate panel 16.

A cet égard, un système de chicane peut permettre d'éviter l'introduction d'un flux d'air entre le panneau intérieur 14 et le second panneau intermédiaire 16.In this respect, a baffle system may make it possible to prevent the introduction of an air flow between the inner panel 14 and the second intermediate panel 16.

Grâce à la meilleure ventilation de la porte, le coût de la porte peut être diminué dès lors qu'il est possible de limiter les traitements infrarouges des différents panneaux de verre juxtaposés.Thanks to the better ventilation of the door, the cost of the door can be reduced when it is possible to limit the infrared treatments of the different juxtaposed glass panels.

En effet, grâce à l'inclinaison des panneaux intermédiaires, le flux de refroidissement n'est plus laminaire entre les différents panneaux mais turbulent de telle sorte que le coefficient de convection est amélioré.Indeed, thanks to the inclination of the intermediate panels, the cooling flow is no longer laminar between the different panels but turbulent so that the convection coefficient is improved.

Grâce à l'augmentation de l'écartement entre deux panneaux, la circulation d'air entre ces panneaux est privilégiée. De préférence, la disposition inclinée de chaque panneau intermédiaire est telle qu'elle permet de ventiler la face chaude du panneau.By increasing the spacing between two panels, the air flow between these panels is preferred. Preferably, the inclined disposition of each intermediate panel is such as to ventilate the hot face of the panel.

Par ailleurs, l'inclinaison des panneaux intermédiaires permet de faire coïncider l'écartement des panneaux en haut et en bas de la porte avec la largeur des ouvertures d'entrée et de sortie d'air dans la porte.Furthermore, the inclination of the intermediate panels makes it possible to match the spacing of the panels at the top and bottom of the door with the width of the inlet and outlet air openings in the door.

La perte de charge du flux d'air en entrée et en sortie de la porte est ainsi limitée, voire supprimée, ce qui permet d'augmenter le débit d'air dans la porte et de dimensionner les ouvertures d'entrée et de sortie d'air suivant les écoulements d'air souhaités dans la porte.The pressure drop of the air flow entering and leaving the door is thus limited or even eliminated, which makes it possible to increase the air flow in the door and to size the inlet and outlet openings of the door. air according to the desired air flows in the door.

Le flux d'air passe ainsi de la porte au conduit de ventilation avec un minimum de pertes de charge.The air flow thus passes from the door to the ventilation duct with a minimum of pressure drops.

Comme précédemment, les panneaux intermédiaires 15, 16 sont montés grâce à des éléments de maintien 17', 17" tels qu'illustrés sur les figures 8 et 11.As previously, the intermediate panels 15, 16 are mounted by means of holding elements 17 ', 17 "as illustrated in FIGS. figures 8 and 11 .

Ces éléments de maintien ont une forme extérieure identique à celle décrite précédemment en référence aux figures 4 à 6 et sont montés de manière identique dans le cadre de porte 12.These holding elements have an outer shape identical to that described above with reference to the Figures 4 to 6 and are mounted identically in the door frame 12.

En revanche, afin d'assurer un montage en position inclinée des deux panneaux intermédiaires 15, 16, chaque éléments de maintien 17', 17" comportent des encoches intérieures 23', 23" disposées dans un plan transversal incliné par rapport à une des faces d'extrémité 17'c, 17"c adaptée à venir en contact avec le panneau intérieur 14 de la porte.On the other hand, in order to ensure an inclined mounting of the two intermediate panels 15, 16, each holding element 17 ', 17 "comprises internal notches 23', 23" disposed in a transverse plane inclined with respect to one of the faces end 17'c, 17 "c adapted to come into contact with the inner panel 14 of the door.

Dans ce mode de réalisation dans lequel chaque élément de maintien 17', 17" comportent des faces d'extrémité 17'b, 17'c, 17"b, 17"d parallèles l'une à l'autre, les encoches intérieures 23', 23" sont disposées dans un plan transversal incliné par rapport à ces deux faces d'extrémité.In this embodiment, in which each holding element 17 ', 17 "has end faces 17'b, 17'c, 17" b, 17 "d parallel to one another, the internal notches 23 ', 23 "are arranged in a transverse plane inclined with respect to these two end faces.

Plus particulièrement, afin d'assurer une distance différente entre les panneaux au niveau du bord supérieur 10a de la porte et du bord inférieur 10b de la porte, les éléments de maintien des panneaux intermédiaires 15, 16 comportent deux paires d'éléments en forme de coin 17', 17".More particularly, to ensure a different distance between the panels at the upper edge 10a of the door and the lower edge 10b of the door, the holding elements of the intermediate panels 15, 16 comprise two pairs of elements in the form of corner 17 ', 17 ".

Une première paire d'éléments de maintien 17', tel qu'illustré sur les figures 8 à 10, est adaptée à équiper les coins supérieurs des panneaux intermédiaires 15, 16 destinés à être disposés à proximité du bord supérieur 10a de la porte. A cet effet, les encoches intérieures 23' sont disposées respectivement dans deux plans inclinés l'un par rapport à l'autre, la distance minimale d' séparant ces encoches 23', tel qu'illustré à la figure 9, correspondant à la distance minimale séparant les panneaux intermédiaires 15, 16 au niveau du bord supérieur 10a de la porte 10.A first pair of holding members 17 ', as illustrated on the Figures 8 to 10 , is adapted to equip the upper corners of the intermediate panels 15, 16 intended to be arranged near the upper edge 10a of the door. For this purpose, the internal notches 23 'are respectively arranged in two inclined planes with respect to each other, the minimum distance separating these notches 23', as illustrated in FIG. figure 9 , corresponding to the minimum distance between the intermediate panels 15, 16 at the upper edge 10a of the door 10.

Symétriquement, la seconde paire d'éléments de maintien 17", tel qu'illustré sur les figures 11 à 13, comportent également deux encoches intérieures 23" disposées respectivement dans deux plans inclinés l'un par rapport à l'autre. La distance maximale d" séparant ces deux encoches intérieures 23" correspond à la distance séparant les panneaux intermédiaires 15, 16 au niveau du bord inférieur 10b de la porte 10. Cette seconde paire d'éléments de maintien 17" est adaptée à équiper les coins inférieurs des panneaux intermédiaires 15, 16 destinés à venir à proximité du bord inférieur 10b de la porte 10 lorsque les panneaux intermédiaires sont montés dans le cadre de porte 12.Symmetrically, the second pair of holding elements 17 ", as illustrated on the Figures 11 to 13 , also comprise two internal notches 23 "disposed respectively in two planes inclined with respect to one another, the maximum distance separating these two internal notches 23" corresponds to the distance separating the intermediate panels 15, 16 at the level of lower edge 10b of the door 10. This second pair of holding elements 17 "is adapted to equip the lower corners of the intermediate panels 15, 16 intended to come close to the lower edge 10b of the door 10 when the intermediate panels are mounted in the door frame 12.

Comme précédemment le montage amovible de ces éléments de maintien 17', 17" permet de monter et démonter de manière assemblée les panneaux intermédiaires 15, 16 dans la porte 10, en vue notamment de faciliter le nettoyage de ces différents panneaux.As previously, the removable assembly of these holding elements 17 ', 17 "makes it possible to assemble and disassemble in an assembled manner the intermediate panels 15, 16 in the door 10, in particular to facilitate the cleaning of these different panels.

Dans ce second mode de réalisation, tous les avantages liés aux caractéristiques du matériau utilisé et au maintien en compression des éléments de maintien 17', 17" dans le cadre de porte sont identiques à ceux décrits précédemment en référence au premier mode de réalisation de l'invention.In this second embodiment, all the advantages related to the characteristics of the material used and the maintenance in compression of the holding elements 17 ', 17 "in the door frame are identical to those described above with reference to the first embodiment of the invention. 'invention.

Des moyens de détrompage peuvent être prévus dans la porte afin de faciliter, lors du montage de la porte, le positionnement des deux paires d'éléments de maintien 17', 17".Keying means may be provided in the door to facilitate, during assembly of the door, the positioning of the two pairs of holding members 17 ', 17 ".

En particulier, un code de couleur peut être déterminé pour distinguer les coins inférieurs des coins supérieurs et permettre leur montage adéquat dans le cadre de porte.In particular, a color code can be determined to distinguish the lower corners of the upper corners and allow their proper mounting in the door frame.

Une autre solution consisterait à modifier la hauteur des formes embouties 12c et la hauteur des éléments en forme de coin 17', 17".Another solution would be to change the height of the stamped shapes 12c and the height of the wedge-shaped elements 17 ', 17 ".

On va décrire à présent en référence aux figures 14 à 20 un troisième mode de réalisation.We will now describe with reference to Figures 14 to 20 a third embodiment.

Dans ce mode de réalisation, comme bien illustré à la figure 14, la porte comporte deux panneaux intermédiaires 15, 16, l'un des deux, à proximité du panneau intérieur 14, étant parallèle aux panneaux intérieur 14 et extérieur 11, et l'autre panneau intermédiaire 15, à proximité du panneau extérieur 11, étant incliné par rapport à ce panneau extérieur 11.In this embodiment, as well illustrated in the figure 14 , the door comprises two intermediate panels 15, 16, one of them, near the inner panel 14, being parallel to the inner 14 and outer 11 panels, and the other intermediate panel 15, near the outer panel 11, being inclined with respect to this outer panel 11.

Les éléments communs au second mode de réalisation décrit précédemment portent les mêmes références numériques et ne seront pas redécrits ci-après.The elements common to the second embodiment described above bear the same reference numerals and will not be described below.

Le premier panneau intermédiaire 15 est incliné comme dans le mode de réalisation précédent, de telle sorte que la distance séparant ce premier panneau intermédiaire 15 du panneau extérieur 11 à proximité du bord inférieur 10b de la porte est inférieure à la distance séparant ce premier panneau intermédiaire 15 du panneau extérieur 11 à proximité du bord supérieur 10a de la porte.The first intermediate panel 15 is inclined as in the previous embodiment, so that the distance between this first intermediate panel 15 of the outer panel 11 near the lower edge 10b of the door is less than the distance between the first intermediate panel. 15 of the outer panel 11 near the upper edge 10a of the door.

En revanche, le second panneau intermédiaire 16 est disposé à une distance uniforme du panneau intérieur 14.On the other hand, the second intermediate panel 16 is arranged at a uniform distance from the inner panel 14.

Par exemple, le second panneau intermédiaire 16 peut être disposé à une distance d'environ 3 mm du panneau intérieur 14.For example, the second intermediate panel 16 may be disposed at a distance of about 3 mm from the inner panel 14.

Comme dans l'exemple de réalisation précédent, le flux d'air établi par le système de ventilation est adapté à circuler uniquement entre le panneau extérieur 11 et le premier panneau intermédiaire 15, et entre le premier panneau intermédiaire 15 et le second panneau intermédiaire 16.As in the previous embodiment, the air flow established by the ventilation system is adapted to circulate only between the outer panel 11 and the first intermediate panel 15, and between the first intermediate panel 15 and the second intermediate panel 16 .

Les panneaux intermédiaires 15, 16 sont également montés de manière amovible dans la porte en vue de faciliter leur nettoyage.The intermediate panels 15, 16 are also removably mounted in the door for easy cleaning.

On a illustré sur les figures 15 à 20 des éléments de maintien 17', 17" en forme de coin et destinés à être montés aux angles des panneaux intermédiaires 15, 16.We have illustrated on Figures 15 to 20 wedge-shaped holding members 17 ', 17 "for mounting at the corners of the intermediate panels 15, 16.

Ces éléments de maintien 17', 17" sont semblables à ceux décrits précédemment en relation avec les figures 8 à 13.These holding elements 17 ', 17 "are similar to those described above in connection with the Figures 8 to 13 .

En particulier, les avantages liés aux caractéristiques du matériau utilisé au maintien en compression des éléments de maintien 17', 17" dans le cadre de porte sont identiques à ceux décrits précédemment.In particular, the advantages related to the characteristics of the material used to maintain in compression the holding elements 17 ', 17 "in the door frame are identical to those described above.

Dans ce mode de réalisation, les encoches intérieures 23', 23" des éléments de maintien 17', 17" sont modifiées pour permettre notamment la disposition du second panneau intermédiaire 16 parallèlement au panneau intérieur 14 de la porte.In this embodiment, the internal notches 23 ', 23 "of the holding elements 17', 17" are modified to allow in particular the provision of the second intermediate panel 16 parallel to the inner panel 14 of the door.

Ainsi, comme illustré sur les figures 15 à 17, une première paire d'éléments de maintien 17' est adaptée à équiper les coins supérieurs des panneaux intermédiaires 15, 16 destinés à être disposés à proximité du bord supérieur 10a de la porte.Thus, as illustrated on Figures 15 to 17 , a first pair of holding elements 17 'is adapted to equip the upper corners of the intermediate panels 15, 16 intended to be arranged near the upper edge 10a of the door.

A cet effet, une première encoche intérieure 23' est disposée dans un plan transversal incliné par rapport à une des faces d'extrémités 17'c de l'élément de maintien 17' et une seconde encoche intérieure 23' est disposée dans un plan parallèle à la face d'extrémité 17'c.For this purpose, a first inner notch 23 'is disposed in a transverse plane inclined with respect to one of the end faces 17'c of the holding member 17' and a second inner notch 23 'is disposed in a parallel plane at the end face 17'c.

Symétriquement, la seconde paire d'éléments de maintien 17" telle qu'illustrée sur les figures 18 à 20, comporte une première encoche intérieure 23" disposée dans un plan transversal incliné par rapport à une des faces d'extrémités 17"c de l'élément de maintien 17" et une seconde encoche intérieure 23" disposée dans un plan parallèle à la face d'extrémité 17"c.Symmetrically, the second pair of holding elements 17 "as illustrated on the Figures 18 to 20 , has a first internal notch 23 "disposed in a transverse plane inclined with respect to one of the end faces 17" c of the holding member 17 "and a second inner notch 23" disposed in a plane parallel to the face d end 17 c.

Cette seconde paire d'éléments de maintien est adaptée à équiper les coins inférieurs des panneaux intermédiaires 15, 16 destinés à venir à proximité du bord inférieur 10b de la porte 10 lorsque les panneaux intermédiaires sont montés dans le cadre de porte 12.This second pair of holding elements is adapted to equip the lower corners of the intermediate panels 15, 16 intended to come close to the lower edge 10b of the door 10 when the intermediate panels are mounted in the door frame 12.

Ce troisième mode de réalisation présente des avantages et caractéristique analogues à ceux décrits précédemment en relation avec les premier et second modes de réalisation de l'invention.This third embodiment has advantages and features similar to those described above in connection with the first and second embodiments of the invention.

Bien entendu, de nombreuses modifications peuvent être apportées aux exemples de réalisation décrits précédemment sans sortir du cadre de l'invention.Of course, many modifications can be made to the embodiments described above without departing from the scope of the invention.

En particulier, seul un unique panneau intermédiaire pourrait être monté parallèlement ou de manière inclinée dans le cadre de porte, entre les panneaux intérieur et extérieur de la porte.In particular, only a single intermediate panel could be mounted parallel or inclined in the door frame, between the inner and outer panels of the door.

Par ailleurs, les éléments en forme de coin pourraient comporter une première encoche pour monter un panneau intermédiaire parallèle à la porte et une seconde encoche pour monter un panneau intermédiaire incliné par rapport à la porte.Moreover, the wedge-shaped elements could comprise a first notch for mounting an intermediate panel parallel to the door and a second notch for mounting an intermediate panel inclined relative to the door.
