“PROCEDIMENTO PER LA REALIZZAZIONE DI UNA LASTRA PER FORNELLI DI COTTURA AD INDUZIONE E LASTRA OTTENUTA CON DETTO PROCEDIMENTO.†⠀ œPROCESS FOR THE REALIZATION OF A SHEET FOR INDUCTION COOKING STOVES AND SHEET OBTAINED WITH THIS PROCEDURE.â €
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente domanda di brevetto per invenzione industriale ha per oggetto un procedimento per la realizzazione di una lastra per fornelli di cottura ad induzione e la lastra ottenuta con detto procedimento. The present patent application for industrial invention relates to a process for making a plate for induction cooking stoves and the plate obtained with said process.
Attualmente tutte le lastre per piani di cottura, in caso di fornelli ad induzione, sono tutte realizzate in vetro-ceramica, un materiale che si à ̈ dimostrato particolarmente idoneo per questo particolare impiego grazie ai suoi bassi coefficienti di dilatazione termica. Currently, all plates for hobs, in the case of induction cookers, are all made of glass-ceramic, a material that has proven to be particularly suitable for this particular use thanks to its low coefficients of thermal expansion.
Il procedimento secondo il trovato à ̈ stato sviluppato al fine di realizzare nuove lastre destinate ad essere utilizzate in seno a piani cottura del tipo ad induzione. The method according to the invention has been developed in order to produce new plates intended to be used in induction-type hobs.
Negli ultimi anni infatti i piani ad induzione hanno preso campo ed il procedimento secondo il trovato à ̈ stato ideato al fine di rendere detti piani fortemente personalizzabili, soprattutto dal punto di vista dell’applicazione di decorazioni, tinte e/o disegni. In fact, in recent years induction hobs have taken up and the process according to the invention has been devised in order to make said hobs highly customizable, especially from the point of view of the application of decorations, colors and / or designs.
Per meglio comprendere le performance di detti piani ad induzione basti pensare che con un indice di rendimento del 90%, (contro un indice del 60% per i piani elettrici in vetroceramica e del 50% dei piani a gas), l’induzione à ̈ la più efficiente ed evoluta tecnologia di cottura, perché offre il vantaggio che il calore viene generato direttamente dal fondo della pentola, con una riduzione anche dei tempi di cottura. To better understand the performance of these induction hobs, just think that with a yield index of 90% (against an index of 60% for electric glass ceramic hobs and 50% for gas hobs), induction is It is the most efficient and advanced cooking technology, because it offers the advantage that the heat is generated directly from the bottom of the pot, also reducing cooking times.
L’induzione garantisce inoltre il massimo grado di sicurezza d’uso, perché il calore si genera direttamente sul fondo della pentola, mentre la superficie del piano non subisce alcun riscaldamento diretto se non per conduzione dalla pentola soprastante, facendo rimanere il resto del piano a temperatura ambiente. The induction also guarantees the maximum degree of safety of use, because the heat is generated directly on the bottom of the pot, while the surface of the hob does not undergo any direct heating except by conduction from the pot above, leaving the rest of the hob at room temperature.
I piani cottura ad induzione sono dotati di speciali bobine ad induzione che generano un campo magnetico e non appena una pentola di materiale ferroso viene appoggiata sulla zona cottura, si attiva una reazione che trasforma l'energia del campo magnetico in calore, che scalda direttamente il fondo della pentola. Induction hobs are equipped with special induction coils that generate a magnetic field and as soon as a pot of ferrous material is placed on the cooking area, a reaction is activated that transforms the energy of the magnetic field into heat, which directly heats the bottom of the pot.
La tecnologia ad induzione negli ultimi anni sta sempre più suscitando interesse. In recent years, induction technology has been attracting more and more interest.
Nei tradizionali piani elettrici, invece, il calore generato dalle resistenze, posizionate sotto la superficie della lastra del piano di cottura, scalda prima la lastra stessa, che per trasmissione scalda la sovrastante pentola, con un evidente inferiore rendimento termico. In traditional electric hobs, on the other hand, the heat generated by the resistances, positioned under the surface of the hob plate, first heats the plate itself, which by transmission heats the overlying pot, with an evident lower thermal efficiency.
Come sopra anticipato le lastre che attualmente vengono utilizzate per detti piani di cottura sono realizzate in vetroceramica. As mentioned above, the plates that are currently used for said cooking hobs are made of glass ceramic.
La vetroceramica usata comunemente ha colorazione scura, anche se recentemente à ̈ iniziata l’utilizzazione di lastre trasparenti, con tonalità giallo arancio, che vengono poi colorate sulla faccia interna del piano cottura, in modo da svolgere sia una azione schermante dei componenti sottostanti sia un’azione decorativa tesa a personalizzare il piano. The commonly used glass ceramic has a dark color, although the use of transparent plates with yellow-orange tones has recently begun, which are then colored on the inner face of the hob, in order to perform both a shielding action on the underlying components and a decorative action aimed at personalizing the top.
Tale vetroceramica trasparente, per via della sua colorazione giallognola, non consente la decorazione con colori chiari senza inevitabilmente cambiarne tonalità ed effetti. This transparent glass ceramic, due to its yellowish color, does not allow decoration with light colors without inevitably changing its tone and effects.
Per l’industria dell’elettrodomestico à ̈ importante la massima flessibilità in materia di colorazione in modo di potersi adattare ai diversi ambienti e colori. For the household appliance industry, maximum flexibility in terms of coloring is important in order to adapt to different environments and colors.
Scopo della presente invenzione à ̈ quello di ideare un procedimento per la realizzazione di una nuova lastra, da utilizzare in seno ai piani di cottura ad induzione, la quale sia completamente trasparente. The purpose of the present invention is to devise a process for making a new plate, to be used within induction hobs, which is completely transparent.
Ulteriore scopo della presente invenzione à ̈ quello di ideare un procedimento per la realizzazione di una nuova lastra, che, oltre a raggiungere lo scopo suddetto, possa essere colorata, senza che la vernice di colorazione prescelta subisca alterazioni di tonalità . A further object of the present invention is to devise a process for making a new plate, which, in addition to achieving the aforementioned purpose, can be colored, without the chosen coloring varnish undergoing tonal changes.
Non ultimo scopo à ̈ quello di ideare un procedimento per la realizzazione di una nuova lastra, la quale oltre a raggiungere tutti gli scopi sopradetti, presenti una resistenza meccanica maggiore rispetto a quelle delle lastre in vetroceramica, riducendo quindi le probabilità di fessurazioni o rotture in caso di urti accidentali superficiali. Not least object is to devise a process for the production of a new plate, which in addition to achieving all the aforementioned purposes, has a higher mechanical resistance than that of glass ceramic plates, thus reducing the probability of cracks or breakages in case of accidental superficial impacts.
Questi ed altri scopi sono stati conseguiti dal procedimento industriale secondo il trovato, le cui caratteristiche principali sono puntualizzate nella prima rivendicazione. These and other objects have been achieved by the industrial process according to the invention, the main characteristics of which are pointed out in the first claim.
Il procedimento secondo il trovato à ̈ stato concepito nell’intento di realizzare una lastra per fornelli ad induzione in materiale trasparente, così da poter creare una molteplicità di piani di cottura attualmente non realizzabili, come ad esempio: The method according to the invention was conceived with the intention of making a plate for induction cookers in transparent material, so as to be able to create a multiplicity of cooking hobs that are currently not feasible, such as:
- un piano ad induzione con una lastra completamente trasparente che mostra tutti i componenti del sottostante fornello ad induzione; - an induction hob with a completely transparent plate showing all the components of the underlying induction cooker;
- un piano ad induzione con una lastra perfettamente bianca; - an induction hob with a perfectly white plate;
- un piano ad induzione con una lastra colorata in cui la tinta della lastra stessa corrisponde al colore prescelto dall’utente. - an induction hob with a colored plate in which the color of the plate corresponds to the color chosen by the user.
Il procedimento in parola prevede di partire da una lastra di vetro borosilicato di spessore variabile preferibilmente tra 3 e 10 mm, circa che viene sagomata e poi sottoposta ad un trattamento termico di “indurimento†. The process in question involves starting from a sheet of borosilicate glass with a thickness preferably between 3 and 10 mm, which is shaped and then subjected to a heat treatment of â € œhardeningâ €.
Detto trattamento à ̈ necessario in quanto il vetro borosilicato se non sottoposto a processo termico di indurimento, non avrebbe le proprietà idonee per sopportare i test di resistenza meccanica previsti dalle normative IEC UL. This treatment is necessary as borosilicate glass, if not subjected to a thermal hardening process, would not have the suitable properties to withstand the mechanical resistance tests required by the IEC UL standards.
Detto vetro borosilicato viene inoltre sottoposto a test, pur se non previsti dalle norme, in cui la pentola in fase di cottura viene lasciata sul piano di cottura fino a far evaporare completamente l’acqua al suo interno, per verificare se la lastra di vetro borosilicato si danneggi prima che i sensori di sovratemperatura del piano disattivino il funzionamento degli induttori. Said borosilicate glass is also subjected to tests, even if not provided for by the standards, in which the pot during cooking is left on the hob until the water inside it evaporates completely, to check whether the glass plate borosilicate is damaged before the overheating sensors of the hob deactivate the operation of the inductors.
In una simile circostanza à ̈ stato sperimentato che la lastra di borosilicato raggiunge, in corrispondenza della sua area sottostante la pentola, una temperatura di 350°C. In a similar circumstance it has been tested that the borosilicate plate reaches, in correspondence with its area under the pot, a temperature of 350 ° C.
Più precisamente la normativa internazionale vigente prevede delle specifiche sui componenti di cottura ad induzione (IEC 60335-2-6- UL 858) a cui i produttori devono attenersi. More precisely, the international legislation in force provides for specifications on induction cooking components (IEC 60335-2-6-UL 858) which manufacturers must comply with.
Grazie a detto trattamento di indurimento, la lastra di vetro borosilicato ottenuta, acquisisce caratteristiche di resistenza termica e meccanica che gli consentono di soddisfare i requisiti richiesti da detta normativa. Thanks to said hardening treatment, the obtained borosilicate glass sheet acquires thermal and mechanical resistance characteristics which allow it to satisfy the requirements of said standard.
Nel caso si voglia colorare la lastra secondo il trovato à ̈ prevista una specifica fase di colorazione in cui la stessa viene colorata e decorata con smalti organici o inorganici. If the sheet according to the invention is to be colored, a specific coloring step is provided in which it is colored and decorated with organic or inorganic enamels.
Nel caso di smalti inorganici la decorazione-colorazione viene attuata prima dell’indurimento della lastra, mentre nel caso di smalti organici detta decorazione-colorazione viene attuata successivamente. In the case of inorganic glazes, the decoration-coloring is carried out before the hardening of the slab, while in the case of organic glazes this decoration-coloring is carried out subsequently.
Grazie a detta decorazione à ̈ possibile disegnare sulla lastra una serie di decorazioni o simboli tipici delle lastre per fornelli ad induzione, segnalando magari le aree sovrastanti i fornelli stessi, oppure la simbologia prevista per i tastifunzione dei fornelli. Thanks to this decoration it is possible to draw on the plate a series of decorations or symbols typical of the plates for induction cookers, perhaps indicating the areas above the cookers themselves, or the symbols provided for the function keys of the cookers.
Nel caso la colorazione-decorazione avvenga con smalti organici à ̈ poi prevista una cottura della lastra coloratadecorata a circa 380°C per 30 minuti, al fine di raggiungere le temperature di essicazione dello smalto stesso, per fare in modo che lo smalto sia fissato correttamente e non venga rovinato durante il normale utilizzo del piano. If the coloring-decoration takes place with organic glazes, the colored plate is then fired at about 380 ° C for 30 minutes, in order to reach the drying temperatures of the glaze itself, to ensure that the glaze is fixed correctly. and is not damaged during normal use of the hob.
Nel caso la colorazione-decorazione avvenga con smalti inorganici, il fissaggio degli stessi avviene durante l’anzidetto trattamento termico di indurimento, dal momento che le temperature raggiunte nel corso di detto trattamento termico di indurimento sono dello stesso ordine di grandezza di quelle necessarie per l’essiccazione degli smalti inorganici. If the coloring-decoration takes place with inorganic enamels, the fixing of the same takes place during the aforementioned hardening heat treatment, since the temperatures reached during said hardening heat treatment are of the same order of magnitude as those necessary for the drying of inorganic glazes.
L’anzidetto trattamento termico prevede che la lastra di vetro borosilicato venga dapprima riscaldata in un apposito forno, fino a temperatura di rammollimento - circa 700° C- in un tempo correlato allo spessore del vetro (circa 55sec/mm) e successivamente sottoposta a raffreddamento forzato con un flusso d’aria ad una pressione variabile fra 10.000 Pa a 15.000 Pa, preferibilmente uniforme su entrambi i lati, così da ridurre simultaneamente la temperatura della lastra in pochi secondi a temperatura ambiente. The aforementioned heat treatment requires that the sheet of borosilicate glass is first heated in a special oven, up to a softening temperature - about 700 ° C - in a time correlated to the thickness of the glass (about 55sec / mm) and subsequently subjected to forced cooling with a flow of air at a pressure ranging from 10,000 Pa to 15,000 Pa, preferably uniform on both sides, so as to simultaneously reduce the temperature of the sheet in a few seconds at room temperature.
La lastra di vetro borosilicato sottoposta a detto trattamento termico subisce una compressione degli strati superficiali sulle entrambe le sue facce, che causa un notevole incremento delle caratteristiche meccaniche e termiche della stessa. The sheet of borosilicate glass subjected to said heat treatment undergoes a compression of the surface layers on both its faces, which causes a considerable increase in its mechanical and thermal characteristics.
