"METODO DI FABBRICAZIONE DI PARTI DI UN ELETTRODOMESTICO ED ELETTRODOMESTICO COMPRENDENTE TALI PARTI" "METHOD OF MANUFACTURING PARTS OF A HOUSEHOLD APPLIANCE AND HOUSEHOLD APPLIANCE INCLUDING SUCH PARTS"
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad un metodo di fabbricazione di parti di un elettrodomestico e ad un elettrodomestico comprendente tali parti. The present invention relates to a method of manufacturing parts of a household appliance and to a household appliance comprising such parts.
Esempi di elettrodomestici che comprendono parti prodotte in accordo agli insegnamenti della presente invenzione sono le lavatrici, le lavasciugatrici, le lavastoviglie o anche, più in generale, i forni o i piani cottura. Examples of household appliances which include parts produced in accordance with the teachings of the present invention are washing machines, washer-dryers, dishwashers or even, more generally, ovens or hobs.
È noto allo stato dell'arte realizzare certe parti degli elettrodomestici in materiale plastico, in particolare in ABS, ovvero Acrilonitrile Butadiene Stirene, una resina stirolica termoplastica ottenuta per polimerizzazione di gomma butadienica con acrilonitrile e stirene o copolimero acrilonitrile/stirene. It is known in the state of the art to produce certain parts of household appliances in plastic material, in particular in ABS, or Acrylonitrile Butadiene Styrene, a thermoplastic styrene resin obtained by polymerization of butadiene rubber with acrylonitrile and styrene or acrylonitrile / styrene copolymer.
In una lavabiancheria, ad esempio, le parti che spesso vengono realizzate con questo materiale sono quelle che non hanno impieghi strutturali (ovvero non sono soggette a carichi meccanici rilevanti), come la cornice che circonda il pannello di chiusura superiore (spesso chiamato "top" in inglese) , il quadro di comando o cruscotto, il cassetto, la cornice dell'oblò e lo zoccolo inferiore. In a washing machine, for example, the parts that are often made with this material are those that have no structural uses (ie they are not subject to significant mechanical loads), such as the frame surrounding the upper closing panel (often called "top" in English), the control panel or dashboard, the drawer, the door frame and the lower plinth.
Il costo di produzione dell'elettrodomestico è direttamente legato, tra l'altro, alle materie prime che servono per la sua realizzazione. The production cost of the household appliance is directly linked, among other things, to the raw materials used for its realization.
Quando 1'elettrodomestico arriva alla fine della propria vita utile viene normalmente smaltito in discariche . When the appliance reaches the end of its useful life, it is normally disposed of in landfills.
Questi fattori, unitamente al fatto che la diffusione degli elettrodomestici interessa larga parte della popolazione causa da un lato un grande sfruttamento delle risorse naturali e, dall'altro, problemi di inquinamento rilevanti . These factors, together with the fact that the diffusion of household appliances affects a large part of the population, on the one hand causes a great exploitation of natural resources and, on the other, significant pollution problems.
Inoltre la necessità di realizzare tali particolari in ABS non è dettata principalmente da necessità tecniche, infatti tali particolari non assolvono tanto a funzioni strutturali, quanto a funzioni di rifinitura. Furthermore, the need to produce these ABS details is not primarily dictated by technical needs, in fact these details do not perform so much to structural functions as to finishing functions.
La lavorazione dell'ABS tuttavia necessita di temperature piuttosto elevate, ad esempio nei processi di lavorazione con stampaggio ad iniezione gli stampi devono essere mantenuti ad una temperatura compresa tra 60°C ed 80°C. However, ABS processing requires rather high temperatures, for example in injection molding processes the molds must be kept at a temperature between 60 ° C and 80 ° C.
Questo comporta che durante la fase di fabbricazione per stampaggio ad iniezione dei particolari di cui sopra, debbano essere fornite quantità di calore relativamente elevate allo stampo con un conseguente fabbisogno energetico relativamente elevato. This implies that during the manufacturing step by injection molding of the above parts, relatively high quantities of heat must be supplied to the mold with a consequent relatively high energy requirement.
La presente invenzione di propone di risolvere questi ed altri inconvenienti mettendo a disposizione un metodo di fabbricazione di parti di un elettrodomestico ed un elettrodomestico comprendente parti realizzate in accordo a tale metodo. The present invention aims to solve these and other drawbacks by providing a method for manufacturing parts of a household appliance and a household appliance comprising parts made according to this method.
1/ idea alla base della presente invenzione è quella di produrre tali parti con ABS riciclato. The idea behind the present invention is to produce such parts with recycled ABS.
Questo consente infatti, vantaggiosamente, di ridurre i problemi sopra indicati, perché il materiale utilizzato per la realizzazione delle parti sopra indicate non incide negativamente sul consumo delle risorse naturali e contribuisce a ridurre l'inquinamento, permettendo di riutilizzare materiale di scarto. This allows, advantageously, to reduce the problems indicated above, because the material used for the realization of the parts indicated above does not negatively affect the consumption of natural resources and helps to reduce pollution, allowing the reuse of waste material.
Inoltre si è notato che tale tipo di ABS consente una lavorazione a temperature più basse, poiché nello stampaggio ad iniezione lo stampo può essere mantenuto a temperature inferiori, comprese tra i 40°C ed i 60°C. Furthermore, it has been noted that this type of ABS allows processing at lower temperatures, since in injection molding the mold can be kept at lower temperatures, between 40 ° C and 60 ° C.
Questo comporta, vantaggiosamente, un minor dispendio energetico durante la fase di fabbricazione. This advantageously involves a lower energy expenditure during the manufacturing phase.
Ulteriori caratteristiche vantaggiose del trovato sono oggetto delle allegate rivendicazioni, che si intendono parte integrante del presente testo. Further advantageous features of the invention are the subject of the attached claims, which are intended as an integral part of the present text.
Queste caratteristiche ed ulteriori vantaggi della presente invenzione risulteranno maggiormente chiari dalla descrizione di un suo esempio di realizzazione mostrato nei disegni annessi, forniti a puro titolo esemplificativo e non limitativo, in cui: These characteristics and further advantages of the present invention will become clearer from the description of an embodiment thereof shown in the attached drawings, provided purely by way of non-limiting example, in which:

- temperatura di fusione per stampaggio ad iniezione compresa tra 210°C e 250°C con una temperatura di stampo compresa circa tra 40°C e 60°C. - melting temperature for injection molding between 210 ° C and 250 ° C with a mold temperature between about 40 ° C and 60 ° C.
Sebbene in linea di principio alcune caratteristiche meccaniche dell'ABS riciclato siano apparentemente inferiori a quelle dell'ABS ottenuto da materie prime non riciclate, tuttavia la richiedente ha scoperto che per le parti non strutturali sopra indicate, (ovvero la cornice che circonda il pannello di chiusura superiore, il quadro di comando, il cassetto, la cornice dell'oblò e lo zoccolo inferiore) le caratteristiche tecniche dell'ABS riciclato sono più che soddisfacenti e consentono al medesimo tempo un notevole risparmio in termini di energia richiesta durante la fabbricazione, oltre a presentare gli altri vantaggi sopra elencati e relativi al riciclo di materiali di scarto. Although in principle some mechanical characteristics of recycled ABS are apparently lower than those of ABS made from non-recycled raw materials, however the applicant found that for the non-structural parts indicated above, (i.e. the frame surrounding the upper closure, the control panel, the drawer, the door frame and the lower plinth) the technical characteristics of recycled ABS are more than satisfactory and at the same time allow considerable savings in terms of energy required during manufacturing, as well as to present the other advantages listed above and related to the recycling of waste materials.
In fig. 1 è mostrata una lavatrice 1 comprendente una cornice 2 che circonda il pannello di chiusura superiore, un cassetto per il caricamento degli agenti di lavaggio 3, un quadro di comando 4, uno zoccolo inferiore 5 ed una cornice dell'oblò 6. In fig. 1 shows a washing machine 1 comprising a frame 2 surrounding the upper closing panel, a drawer for loading the washing agents 3, a control panel 4, a lower plinth 5 and a door frame 6.
In accordo alla presente invenzione tutte queste parti sono realizzabili con un ABS riciclato, come descritto più sopra. According to the present invention, all these parts can be made with a recycled ABS, as described above.
In fig. 2 è mostrato invece un secondo esempio di elettrodomestico, ovvero una lavastoviglie 10 comprendente una cornice 20 che circonda il pannello di chiusura superiore, un quadro di comando 40, uno zoccolo inferiore 50, anch'essi realizzabili analogamente con un ABS riciclato, in accordo agli insegnamenti della presente invenzione . In fig. 2 shows instead a second example of a household appliance, that is a dishwasher 10 comprising a frame 20 surrounding the upper closing panel, a control panel 40, a lower plinth 50, which can also be made similarly with a recycled ABS, in accordance with the teachings of the present invention.
Il processo completo di fabbricazione, a partire dalle materie prime, prevede pertanto almeno i passi di: The complete manufacturing process, starting from raw materials, therefore includes at least the steps of:
- triturare un manufatto in ABS sino a produrre dei granuli, - shred an ABS product until granules are produced,
- riscaldare tali granuli in una pressa ad iniezione sino al raggiungimento di una temperatura di fusione dell'ABS - heating these granules in an injection press until the ABS melting temperature is reached
- riscaldare uno stampo di detta pressa ad iniezione ad una temperatura compresa tra 40°C e 60°C - heating a mold of said injection molding machine to a temperature between 40 ° C and 60 ° C
- iniettare l'ABS fuso in detto stampo. - injecting the melted ABS into said mold.
In questo modo si ottiene vantaggiosamente una riduzione dei costi di fabbricazione, dovendo fornire meno calore allo stampo. In this way, a reduction in manufacturing costs is advantageously obtained, since it is necessary to supply less heat to the mold.
Inoltre le caratteristiche meccaniche delle parti così realizzate sono comunque sufficienti per il loro funzionamento, considerando che sono parti non strutturali e che non sono soggette, durante l'utilizzo a carichi meccanici elevati. Furthermore, the mechanical characteristics of the parts thus made are in any case sufficient for their operation, considering that they are non-structural parts and that they are not subjected to high mechanical loads during use.
Ovviamente è possibile pensare di realizzare anche altre parti di diversi elettrodomestici, quali i quadri di comando, le maniglie, gli zoccoli o parti estetiche o di rifinitura di forni, piani cottura, lavasciugatrici, asciugatrici e simili. Obviously, it is also possible to think of making other parts of different household appliances, such as control panels, handles, plinths or aesthetic or finishing parts of ovens, hobs, washer-dryers, dryers and the like.
