DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce al settore dei dispositivi acquastop per apparecchi elettrodomestici di lavaggio, quali lavastoviglie e lavabiancheria. The present invention relates to the sector of aquastop devices for household washing appliances, such as dishwashers and washing machines.
Più in dettaglio, un dispositivo acquastop comprende: un’elettrovalvola presentante un corpo, un condotto di entrata ed un condotto di uscita, nonché un tubo flessibile interno di flusso di acqua avente un’estremità prossimale associata al condotto di uscita dell’elettrovalvola ed un tubo flessibile esterno di sicurezza disposto intorno al tubo interno, così da definire fra i suddetti tubi interno ed esterno un’intercapedine, nella quale à ̈ disposto un cavo elettrico di comando della suddetta elettrovalvola. More in detail, an aquastop device comprises: a solenoid valve having a body, an inlet and an outlet duct, as well as an internal flexible water flow tube having a proximal end associated with the outlet duct of the Solenoid valve and an external flexible safety pipe arranged around the internal pipe, so as to define a cavity between the aforesaid internal and external pipes, in which an electric cable for controlling the aforesaid solenoid valve is arranged.
In caso di necessità , il dispositivo acquastop permette, a seguito alla chiusura dell'elettrovalvola, di interrompere l’alimentazione di acqua all’apparecchio elettrodomestico. Inoltre, in caso di rottura del tubo interno, il tubo esterno può comunque contenere il flusso di acqua uscente e convogliarlo all’interno dell’elettrodomestico, evitando allagamenti dell’ambiente esterno. In case of need, the acquastop device allows, following the closure of the solenoid valve, to interrupt the water supply to the household appliance. Furthermore, in case of breakage of the internal pipe, the external pipe can still contain the outgoing water flow and convey it inside the appliance, avoiding flooding of the external environment.
Scopo della presente invenzione à ̈ quello di consentire un montaggio semplificato di un dispositivo acquastop del tipo sopra indicato. The purpose of the present invention is to allow a simplified assembly of an aquastop device of the type indicated above.
Tale scopo viene raggiunto grazie ad un gruppo pre-montato per dispositivo acquastop, ad un dispositivo acquastop che lo comprende ed al relativo procedimento di assemblaggio aventi le caratteristiche indicate nelle rivendicazioni che seguono. This object is achieved thanks to a pre-assembled unit for an aquastop device, to an aquastop device which comprises it and to the relative assembly process having the characteristics indicated in the following claims.
Secondo l’invenzione, il gruppo suddetto à ̈ pre-montato separatamente dalla restante parte del dispositivo acquastop, tipicamente un gruppo elettrovalvola con i relativi componenti ed accessori. Vantaggiosamente, la produzione del gruppo premontato può essere automatizzata e tale gruppo può essere gestito unitariamente con evidenti semplificazioni logistiche. According to the invention, the aforesaid group is pre-assembled separately from the remaining part of the water stop device, typically a solenoid valve group with the relative components and accessories. Advantageously, the production of the pre-assembled group can be automated and this group can be managed as a unit with evident logistical simplifications.
Di conseguenza, le varie fasi di assemblaggio e test del gruppo elettrovalvola non sono ostacolate dalla presenza del cavo che – avendo una lunghezza di 2 metri o più - à ̈ alquanto ingombrante e rende complesse le procedure di assemblaggio dei dispositivi convenzionali. Al contrario, il gruppo pre-montato secondo l’invenzione à ̈ assemblato al gruppo elettrovalvola solo quale ultima fase della procedura di assemblaggio del dispositivo acquastop, che una volta montato ha una funzionalità analoga a quella dei dispositivi convenzionali. Consequently, the various assembly and test phases of the solenoid valve unit are not hindered by the presence of the cable which - having a length of 2 meters or more - is quite cumbersome and complicates the assembly procedures of conventional devices. On the contrary, the pre-assembled unit according to the invention is assembled to the solenoid valve unit only as the last step of the assembly procedure of the acquastop device, which once assembled has a similar function to that of conventional devices.
Nel complesso, quindi, i tempi ed i costi del procedimento di montaggio del dispositivo acquastop dell’invenzione risultano decisamente ridotti rispetto a quelli dei dispositivi acquastop convenzionali. Overall, therefore, the times and costs of the assembly process of the aquastop device of the invention are decidedly reduced compared to those of conventional aquastop devices.
E’ancora da notare che il gruppo pre-montato dell’invenzione ha una struttura semplice ed essenziale, costituisce un’entità non suddividibile longitudinalmente in più sezioni poste in serie l’uno dopo l’altra, e - nell’uso del dispositivo acquastop - à ̈ interposto fra l’elettrovalvola e l'apparecchio elettrodomestico connettendoli direttamente. It should also be noted that the pre-assembled unit of the invention has a simple and essential structure, it constitutes an entity that cannot be divided longitudinally into several sections placed in series one after the other, and - in the Use of the acquastop device - it is placed between the solenoid valve and the household appliance by connecting them directly.
Ulteriori vantaggi e caratteristiche della presente invenzione risulteranno evidenti dalla descrizione dettagliata che segue, fornita a titolo di esempio non limitativo con riferimento ai disegni annessi, in cui: Further advantages and characteristics of the present invention will become evident from the following detailed description, provided by way of non-limiting example with reference to the attached drawings, in which:
la figura 1 à ̈ una vista prospettica di un dispositivo acquastop dell’invenzione con un gruppo pre-assemblato separato da un gruppo elettrovalvola, e Figure 1 is a perspective view of an aquastop device of the invention with a pre-assembled unit separated from a solenoid valve unit, and
la figura 2 Ã ̈ una vista in sezione longitudinale del dispositivo acquastop di figura 1 in configurazione assemblata. figure 2 is a longitudinal section view of the aquastop device of figure 1 in assembled configuration.
Un gruppo pre-montato 10 per dispositivo acquastop per apparecchio elettrodomestico di lavaggio, comprende: un tubo flessibile interno 12 di flusso di acqua, un tubo flessibile esterno 14 di sicurezza disposto intorno al tubo interno 12, così da definire fra i tubi interno 12 ed esterno 14 un’intercapedine 16, ed un cavo elettrico 18 avente una porzione centrale disposta nell’intercapedine 16 ed una prima ed un seconda estremità . A pre-assembled unit 10 for an acquastop device for household washing appliances comprises: an internal flexible water flow tube 12, an external safety flexible tube 14 arranged around the internal tube 12, so as to define between the internal tubes 12 and external 14 an interspace 16, and an electric cable 18 having a central portion disposed in the interspace 16 and a first and a second end.
La prima estremità del cavo 18 à ̈ provvista di un connettore elettrico, in particolare una spina 20 avente un corpo 22 di materiale elettricamente isolante da cui protrudono contatti elettrici 24. La seconda estremità del cavo 18 à ̈ provvista di un ulteriore connettore 21 per la connessione in modo di per sé noto all’apparecchio elettrodomestico (non illustrato nelle figure). The first end of the cable 18 is provided with an electrical connector, in particular a plug 20 having a body 22 of electrically insulating material from which electrical contacts protrude 24. The second end of the cable 18 is provided with a further connector 21 for the connection in a way known per se to the household appliance (not shown in the figures).
I due tubi flessibili 12, 14 hanno struttura monolitica e possono essere di materiale e tipologia diversa, oppure essere entrambi di tipo corrugato, preferibilmente di polipropilene. The two flexible pipes 12, 14 have a monolithic structure and can be of different materials and types, or both can be of the corrugated type, preferably of polypropylene.
D’altro canto, il dispositivo acquastop comprende un gruppo elettrovalvola 26 presentante un corpo 28, un condotto di entrata 30 ed un condotto di uscita 32. In modo di per sé noto, il corpo 28 alloggia un otturatore 34 suscettibile di interrompere selettivamente la comunicazione fra i condotti di entrata 30 ed uscita 32. A questo scopo, l’otturatore 34 à ̈ solidale ad un magnete 36 vincolato a traslare entro un passaggio ricavato entro una bobina 38 in cui può essere comandato il passaggio di una corrente elettrica. On the other hand, the aquastop device comprises a solenoid valve assembly 26 having a body 28, an inlet duct 30 and an outlet duct 32. In a per se known manner, the body 28 houses a shutter 34 capable of selectively interrupting the communication between the inlet 30 and outlet 32 conduits. For this purpose, the shutter 34 is integral with a magnet 36 constrained to translate within a passage formed within a coil 38 in which the passage of an electric current can be controlled .
Il gruppo elettrovalvola à ̈ nel suo complesso a tenuta idraulica grazie alla presenza di resine 39 di riempimento degli interstizi. Nel corpo 28 à ̈ inoltre ricavata una sede 40 formata da un incavo rivolto verso l’esterno ed adiacente al condotto di uscita 32. La sede 40 à ̈ destinata ad accogliere – come verrà descritto dettagliatamente in seguito -la spina 20 del cavo 18. The solenoid valve assembly is watertight as a whole thanks to the presence of resins 39 for filling the interstices. In the body 28 there is also obtained a seat 40 formed by a recess facing outwards and adjacent to the outlet duct 32. The seat 40 is intended to accommodate - as will be described in detail below - the pin 20 of the cable 18.
La procedura di montaggio del dispositivo acquastop prevede di realizzare separatamente il gruppo pre-montato 10 e il gruppo elettrovalvola 26. L’assemblaggio dei vari componenti ed accessori appena descritti del gruppo elettrovalvola 26, nonché le procedure di test di quest’ultima risultano così decisamente semplificate, non risentendo dell'ingombro del cavo 18 e dei tubi 12 e 14. The assembly procedure of the acquastop device involves making the pre-assembled group 10 and the solenoid valve group 26 separately. The assembly of the various components and accessories described above of the solenoid valve group 26, as well as the test procedures of the latter. they are thus decidedly simplified, not being affected by the encumbrance of the cable 18 and of the tubes 12 and 14.
Il gruppo pre-montato 10 ed il gruppo elettrovalvola 26 sono uniti assieme calzando un’estremità del tubo flessibile interno 12 sul condotto di uscita 32, su cui à ̈ bloccata da un dispositivo di ritegno, quale una molla a spirale elastica 42 (o in forme di attuazione non illustrate nelle figure una fascetta elastica o un anello di crimpatura), ed inserendo la spina 20 nella sede cava 40. A seguito di tale inserzione, i contatti 24 della spina 20 penetrano in rispettivi passaggi 44 ricavati nel corpo 28 e sfocianti nella sede 40, così da creare un circuito elettrico continuo con connettori elettrici 46 solidali al corpo 28 del gruppo elettrovalvola 26 – ad esempio del tipo a lama (chiamati anche in gergo tecnico “faston†) - che costituiscono i terminali elettrici della bobina 38. La conformazione dell’accoppiamento fra sede 40 e corpo 22 della spina 20 à ̈ tale da evitare la penetrazione di acqua di perdita nei passaggi 44 in cui sono inseriti i contatti 24 della spina 20. The pre-assembled assembly 10 and the solenoid valve assembly 26 are joined together by fitting one end of the internal flexible tube 12 onto the outlet conduit 32, on which it is blocked by a retaining device, such as an elastic spiral spring 42 (or in embodiments not shown in the figures an elastic band or a crimp ring), and inserting the pin 20 in the hollow seat 40. Following this insertion, the contacts 24 of the pin 20 penetrate into respective passages 44 obtained in the body 28 and leading into seat 40, so as to create a continuous electrical circuit with electrical connectors 46 integral with the body 28 of the solenoid valve assembly 26 - for example of the blade type (also called â € œfastonâ € in technical jargon) - which form the terminals of the coil 38. The conformation of the coupling between the seat 40 and the body 22 of the plug 20 is such as to avoid the penetration of leaking water into the passages 44 in which the contacts 24 of the plug 20 are inserted.
Nell’uso del dispositivo acquastop, l'elettrovalvola à ̈ eccitata così da comandare il movimento dell’otturatore 34 mediante una corrente elettrica proveniente dal cavo 18 la cui seconda estremità à ̈ collegata tramite il connettore 21 al circuito interno dell’apparecchio elettrodomestico, a sua volta alimentato dalla rete elettrica in modo analogo a quanto previsto dalla tecnica nota. When using the aquastop device, the solenoid valve is energized so as to control the movement of the shutter 34 by means of an electric current coming from the cable 18 whose second end is connected through the connector 21 to the internal circuit of the household appliance, in turn powered by the electrical network in a manner similar to that envisaged by the known art.
Nel complesso, quindi, tutti i collegamenti elettrici del dispositivo acquastop dell’invenzione risultano stabili ed affidabili, garantendo un’idonea ritenzione del cavo 18 che non può essere rimosso accidentalmente. Inoltre, tali collegamenti sono oltremodo sicuri, in quanto completamente isolati dal contatto con acqua, in particolare eventuale acqua di perdita che si raccoglie nell'intercapedine 16 fra i tubi 12 e 14. Nello stesso tempo, la struttura del dispositivo à ̈ semplice ed essenziale con un numero di componenti ridotto al minimo che ne assicura l’economicità . Overall, therefore, all the electrical connections of the aquastop device of the invention are stable and reliable, guaranteeing suitable retention of the cable 18 which cannot be accidentally removed. Furthermore, these connections are extremely safe, as they are completely isolated from contact with water, in particular any leaking water that collects in the interspace 16 between the pipes 12 and 14. At the same time, the structure of the device is simple and essential. with a number of components reduced to a minimum which ensures their economy.
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. Naturally, the principle of the invention remaining the same, the details of construction and the embodiments may vary widely with respect to those described purely by way of example, without thereby departing from the claimed scope.
