Abstract
Description
L'invention se rapporte à un procédé de nettoyage d'une surface d'une plaque transparente qui est exposée à des fumées. The invention relates to a method for cleaning a surface of a transparent plate which is exposed to fumes.
L'invention se rapporte plus particulièrement à un procédé de nettoyage d'une surface d'une plaque transparente qui est soumise à l'action d'un rayonnement infrarouge et exposée à des fumées. The invention relates more particularly to a method of cleaning a surface of a transparent plate which is subjected to the action of infrared radiation and exposed to fumes.
L'invention se rapporte également aux moyens pour la mise en oeuvre du procédé. The invention also relates to the means for implementing the method.
L'invention s'applique avantageusement, mais non exclusivement à un procédé de nettoyage de vitres de dispositifs de chauffage à foyer fermé, dits inserts. The invention applies advantageously, but not exclusively to a method of cleaning windows of closed hearth heating devices, called inserts.
Les plaques transparentes, dites vitres, qui permettent l'observation d'un foyer sont soumises à l'action de la chaleur et des fumées de combustion qui émanent de ce foyer. The transparent plates, called panes, which allow the observation of a hearth are subjected to the action of heat and combustion fumes which emanate from this hearth.
Le passage des fumées de combustions contre la surface exposée de la vitre engendre le dépôt de particules et vapeurs qui, à la longue, viennent opacifier ladite vitre et la rendent inesthétique. The passage of combustion fumes against the exposed surface of the glass causes the deposition of particles and vapors which, in the long run, cloud the said glass and make it unsightly.
Le dépôt formé est extrêmement tenace et ne peut être éliminé que par action chimique, au moyen de solvants ou de substances contenant un agent chimique puissant, tel de la soude caustique. The deposit formed is extremely stubborn and can only be removed by chemical action, using solvents or substances containing a strong chemical agent, such as caustic soda.
La mise en oeuvre de solvants ou de substances précitées est dangereuse pour les utilisateurs. The use of the aforementioned solvents or substances is dangerous for users.
Un résultat que l'invention vise à obtenir est un procédé qui tout en étant facile à mettre en oeuvre par une personne est sans danger. A result which the invention aims to obtain is a process which, while being easy to implement by a person, is without danger.
Un autre résultat que l'invention vise à obtenir est un procédé qui mette en oeuvre des moyens économiques. Another result which the invention aims to obtain is a process which implements economic means.
A cet effet, l'invention a pour objet un procédé de nettoyage d'une surface d'une plaque transparente qui est soumise à l'action de la chaleur et exposée à des fumées, ce procédé étant notamment caractérisé en ce que, pour nettoyer la surface sujette au dépôt de substances émanant de ces fumées, au lieu d'intervenir directement sur la surface, on chauffe la paroi transparente, à une température et pendant une durée au moins suffisante pour induire l'élimination de la couche de substances. To this end, the subject of the invention is a method of cleaning a surface of a transparent plate which is subjected to the action of heat and exposed to fumes, this method being in particular characterized in that, for cleaning the surface subject to the deposition of substances emanating from these fumes, instead of acting directly on the surface, the transparent wall is heated to a temperature and for a duration at least sufficient to induce the elimination of the layer of substances.
L'invention a également pour objet les moyens pour la mise en oeuvre du procédé. The invention also relates to the means for implementing the method.
L'invention sera bien comprise à la lecture de la description ci-après faite à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente, vu partiellement en coupe dans un plan approximativement vertical, un foyer équipé de moyens pour la mise en oeuvre du procédé de l'invention. The invention will be clearly understood on reading the description below made by way of nonlimiting example, with reference to the appended drawing which represents, seen partially in section in an approximately vertical plane, a hearth equipped with means for the implementation of the method of the invention.
En se reportant au dessin, on voit un foyer 1, c'est à dire un volume V qui reçoit des matières 2 dont la combustion produit un rayonnement infrarouge et des fumées 3. Referring to the drawing, we see a hearth 1, that is to say a volume V which receives materials 2 whose combustion produces infrared radiation and fumes 3.
Le volume V est défini par au moins une paroi 4 transparente, telle une plaque, présentant deux surfaces opposées 4A, 4B dont, d'une part, une surface 4A qui, exposée aux fumées 3, est sujette au dépôt de substances 3A émanant de ces fumées 3 et contre laquelle se forme une couche 3B de substances 3A, d'autre part, une surface 4B, dite surface libre, du coté de laquelle s'effectue normalement l'observation du foyer. The volume V is defined by at least one transparent wall 4, such as a plate, having two opposite surfaces 4A, 4B including, on the one hand, a surface 4A which, exposed to the fumes 3, is subject to the deposition of substances 3A emanating from these fumes 3 and against which a layer 3B of substances 3A is formed, on the other hand, a surface 4B, called the free surface, on the side of which the observation of the hearth is normally carried out.
Pour nettoyer la surface 4A sujette au dépôt de substances 3A émanant de ces fumées 3, au lieu d'intervenir directement sur la surface 3A, on chauffe la paroi transparente 4, à une température et pendant une durée au moins suffisante pour induire l'élimination de la couche 3B de substances 3C. To clean the surface 4A subject to the deposition of substances 3A emanating from these fumes 3, instead of intervening directly on the surface 3A, the transparent wall 4 is heated to a temperature and for a duration at least sufficient to induce elimination of layer 3B of substances 3C.
Pour nettoyer la paroi transparente 4, on la chauffe par réflexion depuis sa surface libre 4B et vers la couche 3B de dépôt, du rayonnement infrarouge produit par le foyer qu'elle jouxte. To clean the transparent wall 4, it is heated by reflection from its free surface 4B and towards the deposition layer 3B, infrared radiation produced by the hearth which it adjoins.
Pour chauffer la paroi transparente 4
- on se munit d'un élément 5 qui, présentant une surface
SA, dite surface utile, de formes et d'étendue sensiblement équivalentes à celles de la surface libre 4B de la paroi transparente 4, présente au moins lune des propriétés que sont les propriétés de réflexion d'un rayonnement infrarouge et de conductibilité thermique réduite,
- on place cet élément 5 en appui par sa surface utile 5A contre la surface libre 4B de la paroi transparente 4 et,
- on maintient l'élément 5 en appui par sa surface libre 5A, cependant qu'on chauffe la paroi transparente 4 jusqu'à ce que la couche 3B de substances soit éliminée.To heat the transparent wall 4
- we have an element 5 which, having a surface
SA, called useful surface, of shapes and extent substantially equivalent to those of the free surface 4B of the transparent wall 4, exhibits at least one of the properties that are the properties of reflection of infrared radiation and of reduced thermal conductivity,
this element 5 is placed in abutment by its useful surface 5A against the free surface 4B of the transparent wall 4 and,
- The element 5 is kept in abutment by its free surface 5A, while the transparent wall 4 is heated until the layer 3B of substances is eliminated.
Le nettoyage de la surface 4A sujette au dépôt de substance est donc obtenu sans intervention directe sur la couche de substances. The cleaning of the surface 4A subject to the deposit of substance is therefore obtained without direct intervention on the layer of substances.
On met en oeuvre un élément 5 en matériau thermiquement isolant et résistant à la chaleur. An element 5 of thermally insulating and heat-resistant material is used.
Après suppression de la couche 3B de substances, on retire l'élément 5 de la surface libre 4B de la plaque transparente 4. After removing the layer 3B of substances, the element 5 is removed from the free surface 4B of the transparent plate 4.
Le procédé de l'invention n'exige donc pas la mise en oeuvre agents chimiques. The process of the invention therefore does not require the use of chemical agents.
L'intervention d'une personne qui met en oeuvre le procédé se limite à la pose, puis à la dépose de l'élément 5 contre la plaque transparente. The intervention of a person who implements the method is limited to the installation, then the removal of the element 5 against the transparent plate.
Le contrôle de la disparition de la couche peut être fait par simple dépose de l'élément 5 placé contre la plaque transparente 4. The disappearance of the layer can be checked by simply removing the element 5 placed against the transparent plate 4.
Les moyens pour la mise en oeuvre du procédé selon l'invention sont remarquables en ce qu'ils consistent en un moyen 5 de chauffage de la paroi transparente 4 à une température et pendant une durée au moins suffisante pour induire l'élimination de la couche 3B de substances 3A. The means for implementing the method according to the invention are remarkable in that they consist of a means 5 for heating the transparent wall 4 to a temperature and for a duration at least sufficient to induce the elimination of the layer. 3B of substances 3A.
Les moyens pour la mise en oeuvre du procédé selon l'invention sont également remarquables en ce qu'ils consiste en
- un élément 5 qui, présentant une surface 5A, dite surface utile, de forme et d'étendue sensiblement équivalentes à celles de la surface libre 4B de la paroi transparente 4 présente au moins l'une des propriétés que sont les propriétés de réflexion d'un rayonnement infrarouge et de conductibilité thermique réduite et
- un moyen 6 de maintien de cet élément 5 en appui contre la surface libre 4B de la paroi transparente 4.The means for implementing the method according to the invention are also remarkable in that they consist of

The element 5 comprises a sheet 5C of metallic material which, of shapes and extent substantially equivalent to those of the free surface 4B of the transparent wall 4, has two opposite faces 5A, 5D of which at least one is reflective for radiation infrared.
L'élément S comprend une plaque 5E de matériau thermiquement isolant qui, de formes et d'étendue sensiblement équivalentes à l'une des deux faces opposées 5A, 5D de la feuille 5C de matériau métallique. The element S comprises a plate 5E of thermally insulating material which, of shapes and extent substantially equivalent to one of the two opposite faces 5A, 5D of the sheet 5C of metallic material.
L'élément 5 comprend avantageusement mais non limitativement
- une feuille 5C de matériau métallique qui, de formes et d'étendue sensiblement équivalentes à celles de la surface libre 4B de la paroi transparente 4, présente deux faces 5A, 5D opposées dont au moins une est réfléchissante pour un rayonnement infrarouge,
- une plaque 5E de matériau thermiquement isolant qui, de formes et d'étendue sensiblement équivalentes à l'une des deux faces opposées 5A, 5D de la feuille 5C de matériau métallique, est, par un moyen à cet effet, maintenu en appui contre l'une des faces opposées 5A, 5D de la feuille 5C de matériau métallique,
