Description

L'invention se rapporte à un élément vitré isolant comprenant au moins deux feuilles de verre séparées l'une de l'autre par un espace et au moins un élément de support, notamment pour enceinte réfrigérée.The invention relates to an insulating glass element comprising at least two sheets of glass separated from each other by a space and at least one support element, especially for refrigerated enclosure.

Les vitrages sont généralement placés dans un cadre permettant de les supporter en vue de leur utilisation dans les domaines où leurs propriétés d'isolation thermique sont recherchées (bâtiment, réfrigération, ....)Glazing is generally placed in a frame allowing them to support for use in areas where their properties of thermal insulation are sought (building, refrigeration, ....)

Il est bien connu que lorsqu'une paroi froide se trouve au contact d'air chaud et humide, celle-ci se couvre d'eau provenant de la condensation de la vapeur d'eau ambiante, cette eau pouvant même se transformer en givre si la température est suffisamment basse. C'est plus précisément lorsque la température de la paroi est inférieure au point de rosée de l'air ambiant que se produit la condensation. Dans le cas des vitrages, la condensation peut apparaítre sur le verre et aussi sur le cadre qui supporte le vitrage, surtout s'il est métallique et donc apte à former un pont thermique.It is well known that when a cold wall is in contact with air hot and humid, this is covered with water coming from the condensation of the ambient water vapor, this water can even turn into frost if the temperature is low enough. It is more precisely when the wall temperature is below the dew point of ambient air produces condensation. In the case of glazing, condensation may appear on the glass and also on the frame that supports the glazing, especially if it is metallic and therefore able to form a thermal bridge.

L'essentiel des moyens qui ont été proposés pour remédier aux inconvénients liés à l'apparition de condensation et à la formation de givre a trait à la limitation des échanges thermiques entre les parois du vitrage. Il a ainsi été proposé d'utiliser des vitrages isolants, formés par la superposition de feuilles de verre séparées les unes des autres par une lame d'air ou par un espace maintenu sous vide, et de les chauffer sur toute la surface du verre au moyen d'une couche électriquement conductrice (EP-A-0 314 477, US-A-3 655 939 et FR-A-2 769 337) ou de fils métalliques alimentés par du courant électrique (CA-A-885052).Most of the resources that have been proposed to remedy the disadvantages related to the appearance of condensation and the formation of frost relates to the limitation of heat exchange between the walls of the glazing. It has been so proposed to use insulating glass, formed by the superposition of separated from each other by an air gap or a maintained space under vacuum, and heat them over the entire surface of the glass by means of a layer electrically conductive (EP-A-0 314 477, US-A-3 655 939 and FR-A-2 769 337) or metal wires powered by electric current (CA-A-885052).

Le problème de la condensation et du givre évoqué précédemment se pose de manière plus spécifique dans le domaine de la réfrigération à température relativement basse mis en oeuvre notamment pour la conservation des aliments surgelés.The problem of condensation and frost mentioned above arises more specifically in the field of temperature refrigeration relatively low implemented in particular for the conservation of food frozen.

Il est habituel d'offrir à la vente les aliments surgelés en les disposant dans des congélateurs ouverts sur le dessus (ou congélateurs "bacs") dont la face avant et/ou au moins une face latérale est (sont) vitrée(s). Cette manière de disposer les aliments présente deux avantages :

  • Figure 00020001
    le premier avantage est que l'on peut rapidement, même en étant éloigné, sélectionner le type d'aliment recherché du fait de la transparence de la face avant,
  • Figure 00020002
    et le deuxième avantage est qu'il est facile de se saisir de l'article finalement choisi puisque le congélateur est en permanence ouvert dans sa partie haute.
    • It is usual to offer for sale frozen food by placing them in freezers open on top (or freezers "bins") whose front and / or at least one side face is (are) glazed (s). This way of arranging food has two advantages:
  • Figure 00020001
    the first advantage is that one can quickly, even while being remote, select the type of food sought because of the transparency of the front face,
  • Figure 00020002
    and the second advantage is that it is easy to seize the article finally chosen since the freezer is permanently open in its upper part.

    • Avec les congélateurs "bacs", et malgré l'usage de vitrages isolants, se pose encore le problème de la condensation ou du givre à la périphérie de la surface vitrée. Du fait de leur exposition au froid, le pourtour du vitrage, moins isolé que le reste de la surface vitrée, et les éléments supportant le vitrage se trouvent extérieurement à une température plus basse que celle de l'air ambiant, ce qui engendre de la condensation à la fois sur le verre et sur le support.With freezers "bins", and despite the use of insulating glass, still poses the problem of condensation or frost on the periphery of the glazed surface. Due to their exposure to cold, the perimeter of the glazing, less isolated that the rest of the glass surface, and the elements supporting the glazing are externally at a lower temperature than that of the ambient air, which causes condensation on both the glass and the support.

    La présence d'eau de condensation ou de givre présente des inconvénients : réduction du champ de vision au travers de l'élément vitré, apparition de moisissures, formation de flaques sur le sol, transfert d'humidité sur la peau, présence d'auréoles sur les vêtements, risque de "collage" de la peau sur les parties givrées, ...The presence of condensation water or frost presents disadvantages: reduction of the field of vision through the glazed element, appearance of mold, puddling on the ground, moisture transfer on the skin, presence of rings on the clothes, risk of "sticking" of the skin on frosted parts, ...

    Pour remédier à ces inconvénients, il est connu de chauffer l'élément vitré au moyen d'un cordon métallique périphérique dissimulé dans le cadre supportant la paroi vitrée. Ce cordon ne donne cependant pas toute satisfaction :

  • Figure 00020003
    il est peu modulable du fait que sa longueur dépend entièrement de la dimension du vitrage,
  • Figure 00020004
    sa mise en oeuvre est délicate et coûteuse car il est nécessaire de ménager une gorge parfaitement calibrée dans l'épaisseur du joint de scellement des feuilles de verre,
  • Figure 00020005
    la surface de contact entre le cordon et le cadre étant faible, le rendement de chauffage est faible, et
  • Figure 00030001
    étant donné qu'il est alimenté par un courant électrique de tension élevée (220 Volts environ), on doit impérativement lui associer un dispositif de sécurité qui coupe le circuit en cas de bris accidentel du vitrage.
    • To overcome these disadvantages, it is known to heat the glazed element by means of a peripheral metal bead concealed in the frame supporting the glass wall. This cord, however, does not give any satisfaction:
  • Figure 00020003
    it is not very flexible because its length depends entirely on the size of the glazing,
  • Figure 00020004
    its implementation is delicate and expensive because it is necessary to provide a perfectly calibrated groove in the thickness of the seal glass sheets,
  • Figure 00020005
    the contact surface between the cord and the frame being small, the heating efficiency is low, and
  • Figure 00030001
    since it is powered by a high voltage electrical current (220 volts), it must be associated with a safety device that cuts the circuit in case of accidental breakage of the glazing.

    • La présente invention a pour but de réaliser un élément vitré isolant formé d'au moins deux feuilles de verre et d'au moins un profilé, qui permet de prévenir l'apparition de condensation et la formation de givre à la périphérie.The present invention aims to provide a formed insulating glazed element at least two sheets of glass and at least one profile, which makes it possible to prevent the appearance of condensation and the formation of frost on the periphery.

    L'invention propose un élément vitré isolant comprenant au moins deux feuilles de verre et au moins un profilé, ledit élément présentant au moins une bordure chauffante sur au moins une face d'au moins une feuille de verre, et la bordure étant recouverte par le profilé et étant réunie au profilé par un joint conducteur de la chaleur. De cette manière, en chauffant le bord du vitrage, on peut maintenir le verre et le profilé à une température supérieure au point de rosée de l'air ambiant, et donc prévenir la formation de condensation et de givre sur le verre.The invention proposes an insulating glazing element comprising at least two glass sheets and at least one profile, said element having at least one heating edge on at least one side of at least one sheet of glass, and the edge being covered by the profile and being joined to the profile by a joint heat conductor. In this way, by heating the edge of the glazing, one can keep the glass and the profile at a temperature above the dew point ambient air, thus preventing the formation of condensation and frost on the glass.

    Dans le contexte de l'invention, lorsque l'élément vitré comprend plusieurs feuilles de verre, on désigne par :

  • Figure 00030002
    "feuille de verre extérieure" la feuille de verre qui se trouve en contact avec l'air ambiant lorsque celle-ci est dans sa position d'utilisation,
  • Figure 00030003
    "feuille de verre intérieure" la feuille de verre qui est au contact de l'air froid produit par l'enceinte réfrigérée, et
  • Figure 00030004
    "feuille intermédiaire" une feuille qui se trouve entre la feuille extérieure et la feuille intérieure,
  • - "face externe" la face d'une feuille de verre qui est dirigée vers l'air ambiant, et
  • Figure 00030005
    "face interne" la face d'une feuille de verre qui est dirigée vers l'air froid.
    • In the context of the invention, when the glazed element comprises several sheets of glass, the term:
  • Figure 00030002
    "outer glass sheet" means the glass sheet which is in contact with the ambient air when the latter is in its position of use,
  • Figure 00030003
    "inner glass sheet" means the glass sheet which is in contact with the cold air produced by the refrigerated enclosure, and
  • Figure 00030004
    "intermediate sheet" means a sheet which lies between the outer sheet and the inner sheet,
  • - "outer face" means the face of a sheet of glass which is directed towards the ambient air, and
  • Figure 00030005
    "inner face" the face of a sheet of glass that is directed towards the cold air.

    • Selon un mode de réalisation préféré, la bordure chauffante est portée par la face externe de la feuille de verre extérieure. De cette manière, la bordure est directement en contact, sur toute sa surface, avec le joint conducteur de la chaleur, ce qui permet de chauffer le profilé avec une efficacité maximale.According to a preferred embodiment, the heating edge is carried by the outer face of the outer glass sheet. In this way, the border is directly in contact, over its entire surface, with the conductive seal of the heat, which allows to heat the profile with maximum efficiency.

    Avantageusement, la bordure chauffante est formée par le dépôt d'émail ou de résine renfermant des particules conductrices de l'électricité, telles que des particules d'argent, de nickel, de zinc, de cuivre, de graphite ou d'un métal précieux tel que l'or, le platine ou le palladium. Les particules d'argent sont préférées, notamment parce qu'elles présentent un rapport conductivité/coût avantageux.Advantageously, the heating edge is formed by the enamel deposit or of resin containing electrically conductive particles, such as particles of silver, nickel, zinc, copper, graphite or metal valuable such as gold, platinum or palladium. The silver particles are particularly because they have a conductivity / cost ratio advantageous.

    L'émail utile à l'invention peut être toute composition comprenant une fritte de verre, éventuellement associée à des pigments (en tant que colorants, ces pigments pouvant faire partie de la fritte), et un médium. La fritte de verre peut être toute fritte de verre permettant de former finalement une matrice vitreuse sur le support, de préférence une matrice qui peut supporter les températures requises pour la trempe thermique (température maximale de l'ordre de 650°C). Pour des considérations de recyclage essentiellement, on préfère une fritte qui ne contient substantiellement pas de plomb. Le médium assure la mise en suspension correcte des particules solides et permet l'application et l'adhésion temporaire de l'émail sur le verre. Le médium est généralement choisi parmi les organiques tels que l'huile de pin, les terpènes, les huiles minérales, les diluants et les résines. La résine utile à l'invention est choisie parmi les résines aptes à former finalement une couche polymère sur le support en verre. De préférence, la résine est une résine époxy, polyimide, silicone, polyester ou polyacrylate.The enamel useful for the invention may be any composition comprising a frit of glass, possibly associated with pigments (as dyes, these pigments that can be part of the frit), and a medium. The glass frit can be any glass frit to finally form a vitreous matrix on the support, preferably a matrix that can withstand the required temperatures for thermal quenching (maximum temperature of the order of 650 ° C). For some recycling considerations essentially, it is preferred a frit that does not contain substantially no lead. The medium ensures the suspension solid particles and allows for the application and temporary enamel on the glass. The medium is generally chosen from organic materials such as as pine oil, terpenes, mineral oils, thinners and resins. The resin useful for the invention is chosen from resins capable of forming finally a polymer layer on the glass support. Preferably, the resin is a epoxy resin, polyimide, silicone, polyester or polyacrylate.

    La bordure chauffante est en général obtenue en déposant la composition d'émail ou de résine polymère renfermant les particules métalliques sur le verre par pulvérisation, par enduction au rouleau ou au rideau, ou par sérigraphie et en soumettant le verre ainsi revêtu à une cuisson à une température de l'ordre de 500 à 650°C lorsqu'il s'agit d'émail et de 100 à 200°C dans le cas d'une résine. De manière préférée, on procède par sérigraphie.The heating edge is generally obtained by depositing the composition of enamel or polymer resin containing the metal particles on the glass by spraying, roll or curtain coating, or screen printing and subjecting the coated glass to baking at a temperature of about 500 at 650 ° C in the case of enamel and 100 to 200 ° C in the case of a resin. Of preferred way, one proceeds by screen printing.

    La bordure peut s'étendre sur toute la longueur d'un côté de la (des) feuille(s) de verre en question, ou occuper seulement une partie de la longueur. Les extrémités de la bordure sont pourvues d'éléments d'amenée du courant, par exemple des cosses soudées ou collées, permettant de chauffer la bordure sur toute sa longueur. Selon l'utilisation envisagée, la bordure peut être disposée sur un seul côté ou sur plusieurs côtés. De préférence, la bordure est portée par au moins deux côtés, avantageusement opposés, et mieux encore par trois ou quatre côtés. Dans ce dernier cas, la bordure est avantageusement continue et raccordée en ses deux extrémités au courant électrique.The border may extend the entire length of one side of the sheet (s) of glass in question, or occupy only part of the length. The ends of the border are provided with current feed elements, by example of welded or glued lugs, to heat the edge on all its length. Depending on the intended use, the border may be arranged on only one side or on several sides. Preferably, the border is worn by at least two sides, advantageously opposite, and better still by three or four sides. In the latter case, the border is advantageously continuous and connected at both ends to the electric current.

    La longueur, la largeur, l'épaisseur et la forme de la bordure ne sont pas critiques. A cet égard, l'invention permet de moduler et d'optimiser facilement l'intensité de chauffage de la bordure : en jouant notamment sur la largeur, on peut facilement obtenir des parties plus chauffées que d'autres au sein d'une même bande ou de plusieurs bandes. Il est toutefois préférable de choisir une forme et une taille telles que la bordure puisse être cachée par le profilé supportant les feuilles de verre. Outre l'aspect esthétique indéniable, le recouvrement par le profilé permet, lorsque la bordure est portée par la face externe de la feuille extérieure, de la protéger des dégradations ultérieures, comme par exemple celles qui résultent de l'application de certains produits de nettoyage.The length, width, thickness, and shape of the border are not criticism. In this respect, the invention makes it possible to modulate and optimize easily the intensity of heating of the border: by playing in particular on the width, one can easily get more heated parts than others within a single band or several bands. However, it is best to choose a shape and a size such that the edge can be hidden by the profile supporting the glass sheets. In addition to the undeniable aesthetic aspect, the recovery by the profile allows, when the border is carried by the outer face of the sheet outside, to protect it from further damage, such as which result from the application of certain cleaning products.

    Le joint thermiquement conducteur est généralement constitué d'une matière polymère comprenant des particules conductrices, par exemple un silicone ou une résine époxy en association avec des particules d'alumine.The thermally conductive seal is generally made of a polymeric material comprising conductive particles, for example a silicone or an epoxy resin in combination with alumina particles.

    Selon un deuxième mode de réalisation, la bordure chauffante est portée par la face interne de la feuille de verre extérieure.According to a second embodiment, the heating edge is worn by the inner face of the outer glass sheet.

    Selon un troisième mode de réalisation, la bordure chauffante est située sur la face externe d'une feuille de verre intermédiaire ou d'une feuille de verre intérieure.According to a third embodiment, the heating edge is located on the outer surface of an intermediate glass sheet or a glass sheet interior.

    Conformément au deuxième et au troisième mode de réalisation, il est avantageux d'associer à la bordure chauffante un élément intermédiaire qui peut conduire la chaleur. Cet élément intermédiaire peut par exemple être une feuille métallique dont au moins une des extrémités est repliée pour former un angle sensiblement droit ou un profilé métallique en L ou en T, et une des extrémités étant liée à la bordure, par exemple par soudure ou collage, et l'autre ou une autre extrémité libre étant disposée parallèlement à l'épaisseur de la feuille de verre portant la bordure. Cette manière d'opérer confère une plus grande surface de contact entre la bordure et le joint thermiquement conducteur, ce qui, par voie de conséquence permet d'accroítre l'efficacité de chauffage du profilé supportant les feuilles de verre.In accordance with the second and third embodiments, it is advantageous to associate with the heating edge an intermediate element which can drive the heat. This intermediate element may for example be a sheet metal of which at least one end is folded to form an angle substantially straight or metal section in L or T, and one end being bound to the border, for example by welding or gluing, and the other or another free end being arranged parallel to the thickness of the glass sheet carrying the border. This way of operating confers a greater surface of contact between the edge and the thermally conductive seal, which, by way of Consequently, it is possible to increase the heating efficiency of the profile supporting the glass sheets.

    De manière préférée, et indépendamment du mode de réalisation, l'élément vitré comporte au moins deux feuilles de verre séparées l'une de l'autre par un espace et réunies à leur périphérie par un joint de scellage, avantageusement étanche à l'eau. De manière particulièrement préférée, l'élément est constitué de trois feuilles de verre.Preferably, and independently of the embodiment, the element glazed window comprises at least two glass sheets separated from one another by a space and joined at their periphery by a seal, advantageously waterproof. In a particularly preferred manner, the element consists of three sheets of glass.

    Selon une variante de l'invention, la feuille extérieure est une feuille de verre ayant subi une trempe thermique. La trempe thermique permet de générer des contraintes importantes dans le verre de sorte que, lorsqu'il est brisé accidentellement, il se fragmente en morceaux suffisamment petits pour ne pas occasionner de blessures. L'étape de trempe est une opération connue en soi : à titre d'illustration, on peut par exemple effectuer la trempe à une température de l'ordre de 550 à 650°C pendant 2 à 4 minutes selon l'épaisseur du verre. Lorsque cette feuille porte une ou plusieurs bordures chauffantes sous la forme d'un dépôt d'émail, la trempe permet aussi d'effectuer la cuisson de l'émail.According to one variant of the invention, the outer sheet is a sheet of heat-treated glass. Thermal quenching makes it possible to generate important constraints in the glass so that when broken accidentally, it breaks up into pieces small enough not to cause injury. The quenching step is an operation known per se: As an illustration, it is possible, for example, to quench at a temperature of the order of 550 to 650 ° C for 2 to 4 minutes depending on the thickness of the glass. When this sheet carries one or more heating edges in the form of a deposit Enamel, tempering also allows to enamel cooking.
