"Componente con guarnizione integrata per apparecchio elettrodomestico†"Component with integrated gasket for household appliance⠀
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce al settore dei componenti per il trattamento dell’acqua per apparecchi elettrodomestici aventi una vasca di lavaggio, in particolare macchine lavastoviglie. The present invention relates to the sector of components for water treatment for household appliances having a washing tank, in particular dishwashing machines.
Più in particolare un tale componente – in particolare un dispositivo distributore di acqua (chiamato comunemente “air-break†) o un decalcificatore di acqua - comprende un corpo di materiale plastico avente almeno una porzione destinata alla connessione con un ulteriore elemento dell'apparecchio elettrodomestico. Poiché fra i vari componenti connessi ha tipicamente luogo un flusso di acqua, le connessioni sono provviste di guarnizioni di tenuta volte ad evitare perdite. More specifically, such a component - in particular a water dispensing device (commonly called â € œair-breakâ €) or a water softener - comprises a body of plastic material having at least a portion intended for connection with a further element of the household appliance. Since a flow of water typically takes place between the various connected components, the connections are equipped with sealing gaskets to prevent leaks.
Secondo la tecnica nota, tali guarnizioni costituiscono elementi ulteriori che vengono posti in sede dal produttore del componente o dall'assemblatore finale dell’apparecchio, richiedendo così una specifica fase di montaggio con propri costi e complicazioni di processo. According to the known art, these gaskets constitute additional elements which are placed in place by the manufacturer of the component or by the final assembler of the apparatus, thus requiring a specific assembly step with its own costs and process complications.
Inoltre, le guarnizioni possono fuoriuscire dalla propria sede in occasione delle manipolazioni che subiscono durante il trasporto dal sito di produzione del componente a quello di assemblaggio agli altri componenti dell’apparecchio elettrodomestico, nonché durante quest’ultima operazione. Furthermore, the gaskets can come out of their seat during the manipulations they undergo during transport from the component production site to the assembly site to the other components of the household appliance, as well as during this last operation.
Uno scopo della presente invenzione à ̈ dunque quello di evitare gli inconvenienti sopra menzionati della tecnica nota. An object of the present invention is therefore to avoid the aforementioned drawbacks of the known art.
Secondo l’invenzione, tale scopo viene raggiunto da un componente e da un apparecchio elettrodomestico che lo comprende, nonché dai relativi procedimenti di produzione aventi le caratteristiche indicate in una o più delle rivendicazioni che seguono. According to the invention, this object is achieved by a component and by a household appliance comprising it, as well as by the relative production processes having the characteristics indicated in one or more of the following claims.
In queste rivendicazioni, con l’espressione “stabilmente associata†si intende che la guarnizione, in assenza di deliberati sforzi di separazione esercitati su di essa da un operatore esterno, resta fissata al componente anche se quest’ultimo à ̈ ancora separato dagli altri componenti dell’apparecchio elettrodomestico ai quali à ̈ tipicamente collegato. In these claims, the expression `` permanently associated '' means that the gasket, in the absence of deliberate separation efforts exerted on it by an external operator, remains fixed to the component even if the latter is still separate from the other components of the household appliance to which it is typically connected.
Poiché, secondo l’invenzione, la guarnizione à ̈ associata stabilmente al relativo componente, quale un dispositivo distributore o un decalcificatore, essa non richiede una fase separata per il montaggio, né può fuoriuscire dalla propria sede durante il trasporto e l’assemblaggio del componente al relativo apparecchio elettrodomestico, compromettendo così la tenuta idraulica di quest’ultimo che deve essere scartato o comunque sottoposto ad una revisione per consentire di individuare l’origine delle fughe d’acqua e porvi rimedio. Since, according to the invention, the gasket is stably associated with the relative component, such as a distributor device or a descaler, it does not require a separate phase for assembly, nor can it come out of its seat during transport and Assembly of the component to the relative household appliance, thus compromising the hydraulic seal of the latter which must be discarded or in any case subjected to overhaul to allow the origin of the water leaks to be identified and remedied.
Si ottengono così vantaggi non trascurabili in termini di economia del processo di assemblaggio e di miglioramento della qualità della produzione. In this way, not negligible advantages are obtained in terms of economy of the assembly process and improvement of production quality.
Ulteriori vantaggi e caratteristiche della presente invenzione risulteranno evidenti dalla descrizione dettagliata che segue, fornita a titolo di esempio non limitativo con riferimento al disegno annesso, in cui la figura unica à ̈ una vista prospettica esplosa di parte di un apparecchio elettrodomestico di lavaggio comprendente componenti realizzati secondo l’invenzione. Further advantages and characteristics of the present invention will become evident from the detailed description that follows, provided by way of non-limiting example with reference to the attached drawing, in which the single figure is an exploded perspective view of part of a household washing appliance comprising components made according to the invention.
Un apparecchio elettrodomestico avente una vasca di lavaggio, in particolare una macchina lavastoviglie, comprende un dispositivo 10 distributore di acqua avente forma sostanzialmente piatta e presentante, su di una sua faccia intorno ad un orifizio 12, una sede sostanzialmente circolare cui à ̈ stabilmente associata una guarnizione 14. A household appliance having a washing tub, in particular a dishwashing machine, comprises a water dispensing device 10 having a substantially flat shape and having, on one of its faces around an orifice 12, a substantially circular seat to which a gasket 14.
Tale faccia à ̈ rivolta verso una lamiera 16 facente parte di una parete laterale della vasca di lavaggio dell’ apparecchio elettrodomestico e presentante un foro circolare 17 di dimensioni corrispondenti a quelle della sede, che viene chiuso da una ghiera 18. In modo di per sé noto, si viene così a formare un passaggio per l’evacuazione dei vapori che si formano nella vasca di lavaggio durante il funzionamento dell’apparecchio. This face is turned towards a sheet 16 forming part of a side wall of the washing tank of the household appliance and presenting a circular hole 17 of dimensions corresponding to those of the seat, which is closed by a ring 18. In order to as it is known, a passage is thus formed for the evacuation of the vapors that form in the washing tank during the operation of the appliance.
Dal dispositivo distributore 10 protrudono inferiormente, in modo di per sé noto, un primo manicotto 20 per la connessione ad un tubo 22 di alimentazione dell’acqua di rete, un secondo manicotto 24 per l’invio di acqua da decalcificare ad un decalcificatore 26 ed un terzo manicotto 28 per l’invio al decalcificatore 26 dell’acqua necessaria alla formazione di una salamoia di rigenerazione. Una ulteriore guarnizione 30 à ̈ stabilmente associata intorno al primo manicotto 20. From the dispensing device 10 protrude from below, in a per se known manner, a first sleeve 20 for connection to a mains water supply pipe 22, a second sleeve 24 for sending water to be decalcified to a decalcifier 26 and a third sleeve 28 for sending to the decalcifier 26 the water necessary for the formation of a regeneration brine. A further gasket 30 is stably associated around the first sleeve 20.
Il decalcificatore 26 comprende in modo di per sé noto un primo serbatoio per il contenimento di sostanze con proprietà decalcificanti, che à ̈ provvisto di un primo condotto 31 per l’entrata di acqua da decalcificare e di un secondo condotto 32 per l’ingresso dell’acqua necessaria alla formazione della salamoia di rigenerazione. Entro l’imboccatura dei condotti 31, 32, che si accoppiano rispettivamente con il secondo 24 ed il terzo 28 manicotto del dispositivo distributore 10, à ̈ stabilmente associata una rispettiva guarnizione 34. The decalcifier 26 comprises in a per se known manner a first tank for containing substances with descaling properties, which is provided with a first duct 31 for the entry of the water to be decalcified and a second duct 32 for the descaling. Inlet of the water necessary for the formation of the regeneration brine. A respective gasket 34 is stably associated within the mouth of the ducts 31, 32, which couple respectively with the second 24 and the third 28 sleeve of the distributor device 10.
Il decalcificatore 26 comprende inoltre – sempre in modo di per sé noto - un secondo serbatoio per il contenimento di sale, nel quale viene fatto passare il flusso di acqua sopra menzionato destinato alla formazione della salamoia di rigenerazione. The decalcifier 26 also comprises - again in a per se known manner - a second tank for containing salt, into which the aforementioned flow of water intended for the formation of the regeneration brine is made to pass.
Normalmente, l’acqua di rete alimentata all’apparecchio elettrodomestico viene fatta passare nel primo serbatoio per abbatterne la durezza. Ciò determina un progressivo esaurimento delle sostanze con proprietà decalcificanti, che devono essere periodicamente rigenerate. Tale rigenerazione ha luogo facendo periodicamente passare attraverso di esse il flusso di salamoia formatasi nel secondo serbatoio. Normally, the mains water fed to the household appliance is passed into the first tank to reduce its hardness. This determines a progressive exhaustion of substances with descaling properties, which must be periodically regenerated. This regeneration takes place by periodically passing through them the flow of brine formed in the second tank.
Quest’ultimo presenta un bocchettone 36 per il caricamento al suo interno del sale che viene consumato per formare la salamoia. Una prima guarnizione 38 à ̈ stabilmente associata intorno al bocchettone 36. The latter has a nozzle 36 for loading inside the salt which is consumed to form the brine. A first gasket 38 is stably associated around the union 36.
Quest’ultimo passa attraverso un foro 40 ricavato in una lamiera 42 facente parte del fondo dalla vasca di lavaggio dell’apparecchio elettrodomestico, alla quale à ̈ associato mediante una ghiera 44. La tenuta dell’accoppiamento fra ghiera 44 e bocchettone 36 à ̈ garantita da una seconda guarnizione 46 stabilmente associata alla base di quest'ultimo. Un tappo 48, la cui tenuta à ̈ garantita dalla prima guarnizione 38, chiude il bocchettone 36. The latter passes through a hole 40 obtained in a sheet 42 forming part of the bottom of the washing tank of the household appliance, to which it is associated by means of a ring nut 44. The seal of the coupling between ring nut 44 and union 36 It is guaranteed by a second gasket 46 stably associated with the base of the latter. A cap 48, whose tightness is guaranteed by the first gasket 38, closes the union 36.
Le guarnizioni 14, 30, 34, 38, 46 possono essere di materiale termoplastico o elastomerico diverso dal materiale polimerico con cui sono realizzati i corpi del dispositivo e del decalcificatore. Le guarnizioni 14, 30, 34, 38, 46 possono essere stabilmente associate al rispettivo componente sostanzialmente contemporaneamente alla sua formazione, ad esempio mediante co-stampaggio o colata, oppure successivamente, ad esempio mediante colata. The gaskets 14, 30, 34, 38, 46 can be of thermoplastic or elastomeric material different from the polymeric material with which the bodies of the device and of the decalcifier are made. The gaskets 14, 30, 34, 38, 46 can be stably associated with the respective component substantially simultaneously with its formation, for example by co-molding or casting, or subsequently, for example by casting.
Naturalmente, fermo restando il principio dell'invenzione, i particolari di realizzazione e le forme di attuazione potranno ampiamente variare rispetto a quanto descritto a puro titolo esemplificativo, senza per questo uscire dall’ambito rivendicato. In particolare, l’apparecchio elettrodomestico può essere provvisto sia di un dispositivo distributore 10 sia di un decalcificatore 26 del tipo appena descritto, oppure di uno solo di questi componenti, cui sono state stabilmente associate una o più guarnizioni nel modo sopra indicato. Naturally, the principle of the invention remaining the same, the details of construction and the embodiments may widely vary with respect to those described purely by way of example, without thereby departing from the claimed scope. In particular, the household appliance can be provided with either a distributor device 10 or a decalcifier 26 of the type just described, or with only one of these components, to which one or more gaskets have been stably associated in the manner indicated above.
