NUOVA RESISTENZA ELETTRICA CON RIDISTRIBUZIONE SPAZIALE DELLA POTENZA PER ASCIUGACAPELLI E APPARECCHI SIMILI NEW ELECTRIC RESISTANCE WITH SPATIAL POWER REDISTRIBUTION FOR HAIR DRYERS AND SIMILAR APPLIANCES

RIASSUNTO SUMMARY

Nuova resistenza elettrica ad onda per asciugacapelli e apparecchi simili ottenuta applicando, durante la costruzione, la variazione del numero di onde al giro e/o al settore permettendo il controllo totale della ridistribuzione spaziale della potenza garantendo benefici in termini costruttivi, di prestazioni e rendimento. New electric wave resistance for hair dryers and similar appliances obtained by applying, during construction, the variation in the number of waves per revolution and / or sector allowing total control of the spatial redistribution of power, guaranteeing benefits in terms of construction, performance and efficiency.

DESCRIZIONE DESCRIPTION

La presente invenzione riguarda la resistenza elettrica, con filo resistivo sagomato ad onda o simili, per asciugacapelli ed apparecchi simili, che presenta delle caratteristiche tecniche molto positive sia dal punto di vista costruttivo che delle prestazioni e del rendimento. The present invention relates to the electrical resistance, with wave-shaped resistive wire or the like, for hair dryers and similar appliances, which has very positive technical characteristics both from the construction point of view and from the performance and efficiency point of view.

Normalmente le resistenze elettriche con filo resistivo ad onda (che a seconda del metodo di sagomatura del filo resistivo possono prendere anche nomi equivalenti come resistenze con filo a zig-zag, a sinusoide ovvero ondulato, a greca ovvero con forma geometriche particolari, ecc..) sono costruite con uno o più fili avvolti a spire allineate su di un supporto isolante. Normally electric resistors with wave resistive wire (which depending on the method of shaping the resistive wire can also take equivalent names such as resistors with zig-zag wire, sinusoid or wavy, Greek or with particular geometric shape, etc. ) are built with one or more wires wound in coils aligned on an insulating support.

Per la forma periodica della sagomatura del filo si può osservare come, in tutte le resistenze elettriche ora prodotte, risulti essere costante il numero di onde per spira lungo tutto l avvolgimento e/o costante il numero di onde per ogni settore della spira, (fig. 1, fig. 2) For the periodic shape of the wire shaping it can be observed that, in all the electrical resistances now produced, the number of waves per turn along the whole winding is constant and / or the number of waves for each sector of the loop is constant (fig . 1, fig. 2)

Questa costruzione non permette di controllare la distribuzione della potenza sul corpo dell’elemento riscaldante (resistenza) comportando l’impossibilità di adottare evidenti scelte progettuali. This construction does not allow to control the distribution of power on the body of the heating element (resistance), making it impossible to adopt obvious design choices.

- Durante il funzionamento il flusso dell’aria investe la resistenza longitudinalmente, i primi avvolgimenti sono ben dissipati da aria fresca, mentre i successivi sono coperti dai primi e parzialmente investiti da aria calda. La ragione vuole che la maggior potenza possibile sia dissipata sui primi giri e molta meno verso gli ultimi: le costruzioni attuali non consentono di seguire questa logica. - During operation, the air flow hits the resistance longitudinally, the first windings are well dissipated by fresh air, while the subsequent ones are covered by the first and partially hit by hot air. The reason is that as much power as possible is dissipated on the first laps and much less towards the last ones: the current constructions do not allow to follow this logic.

- Dove le resistenze che hanno un andamento conico oppure dove i raggi delle spire di avvolgimento sono variabili, l avvolgimento del punto con raggio di curvatura inferiore influenza la costruzione dell’ avvolgimento di tutta la resistenza, portando ad avere un numero di onde al giro, sui tratti con raggio di curvatura maggiore, minore di quello massimo possibile. La ragione vuole che, dove sia possibile, deve essere inserita maggiore potenza: le costruzioni attuali non consentono di seguire questa logica, (fig. - Where the resistances that have a conical course or where the radii of the winding turns are variable, the winding of the point with a lower radius of curvature influences the construction of the winding of all the resistance, leading to a number of waves per revolution, on the sections with a greater radius of curvature, less than the maximum possible. The reason has it that, where it is possible, more power must be inserted: the current constructions do not allow to follow this logic, (fig.

- Può succedere che la presenza di cavi, elementi di vincolo del motore ecc.., vadano ad ostruire e influenzare il flusso dell’ aria portando ad avere zone della resistenza parzialmente investite dal flusso di aria: queste zone tendono a surriscaldarsi. La ragione vuole che in queste zone debba essere ridotta la potenza: le costruzioni attuali non consentono di seguire questa logica. - It may happen that the presence of cables, engine restraint elements, etc. .., obstruct and influence the air flow leading to areas of the resistance partially hit by the air flow: these areas tend to overheat. The reason has it that in these areas the power must be reduced: the current constructions do not allow to follow this logic.

Ad oggi i problemi di questo tipo possono essere risolti solo in seguito a studi molto complessi sulle geometrie del supporto dell’ avvolgimento e riducendo la potenza dell’ intera resistenza. To date, problems of this type can only be solved following very complex studies on the geometry of the winding support and reducing the power of the entire resistance.

Il metodo presentato per la ridistribuzione della potenza consiste nella possibilità di variare, in modo del tutto arbitrario, il numero di onde al giro o al settore durante l’avvolgimento, (fig. 3, fig. 4, fig. 5, fig. 6, fig. 7) The method presented for the redistribution of power consists in the possibility of varying, in a completely arbitrary way, the number of waves per revolution or sector during winding, (fig. 3, fig. 4, fig. 5, fig. 6 , fig. 7)

Oltre ai benefici di rendimento che il metodo presentato permette risolvendo i problemi precedentemente elencati, si aggiungono altre due benefici: In addition to the performance benefits that the presented method allows by solving the problems listed above, two other benefits are added:

- beneficio in termini di prestazioni, permettendo l’aumento della potenza introducendo un numero maggiore di onde dove il raggio di curvatura lo consenta; - benefit in terms of performance, allowing the increase in power by introducing a greater number of waves where the radius of curvature allows it;

- introdurre un beneficio costruttivo garantendo una solidità strutturale maggiore dell’ avvolgimento, che viene ottenuto accompagnando le esigenze dettate dall’elasticità del filo sagomato, variando il numero di onde (e quindi la tensione di avvolgimento) in modo localizzato. - introducing a constructive benefit by ensuring a greater structural solidity of the winding, which is obtained by accompanying the needs dictated by the elasticity of the shaped wire, by varying the number of waves (and therefore the winding tension) in a localized way.

Come si evince da fig. 3 e fig. 4, il metodo presentato comporta che il numero delle onde possa cambiare al cambiare del raggio di curvatura, oppure più in generale da fig. 5 si osserva che il numero di onde può variare lungo le spire dell’ avvolgimento, da fig. 6 invece si vede come la variazione è localizzata ad un settore, mentre da fig. 7 la variazione è localizzata ad una zona. As can be seen from fig. 3 and fig. 4, the method presented implies that the number of waves can change as the radius of curvature changes, or more generally from fig. 5 it is observed that the number of waves can vary along the coils of the winding, from fig. 6 instead it can be seen how the variation is localized to a sector, while from fig. 7 the variation is localized to a zone.

Dovrebbe risultare chiaro a coloro esperti nella tecnica che la presente invenzione raggiunge gli scopi prefissi. Deve tuttavia essere evidente che agli esempi di realizzazione descritti a titolo illustrativo e non limitativo, potranno essere apportate numerose modifiche, adattamenti, integrazioni, varianti, e sostituzioni senza peraltro uscire dall 'ambito dell 'invenzione. It should be clear to those skilled in the art that the present invention achieves the intended objects. However, it must be evident that numerous modifications, adaptations, additions, variants, and replacements can be made to the embodiment examples described for illustrative and non-limiting purposes, without however departing from the scope of the invention.
