DESCRIZIONE DESCRIPTION
del modello industriale di utilità avente per titolo: of the industrial utility model entitled:
“Asciugacapelli azionato da un motore a poli schermati gestito da un microinvertitore” "Hair dryer driven by a shielded pole motor managed by a micro-inverter"
Il presente trovato concerne un asciugacapelli azionato da un motore a poli schermati gestito da un microinvertitore. The present invention relates to a hairdryer operated by a shielded pole motor managed by a micro-inverter.
Normalmente gli asciugacapelli sono azionati da motori elettrici a collettore, aventi la peculiarità di comprendere carboni di contatto. Normally the hair dryers are operated by electric collector motors, having the peculiarity of comprising contact coals.
Detta soluzione costruttiva presenta alcuni inconvenienti: This constructive solution has some drawbacks:
la vita del motore è legata alla durata dei carboni di contatto; the life of the engine is linked to the duration of the contact coals;
lo strisciamento del carbone sul collettore genera fastidiosi rumori; l’interazione tra carbone e collettore provoca lemissione di particelle di grafite. the sliding of the coal on the collector generates annoying noises; the interaction between coal and collector causes the emission of graphite particles.
Sono noti inoltre asciugacapelli con motore ad induzione a poli schermati che però non riescono a garantire una adeguata velocità di rotazione alla ventola di alimentazione dellaria. Un asciugacapelli professionale ha bisogno di velocità di rotazioni comprese tra 13000 e 20000 giri al minuto, mentre negli apparecchi sopra menzionati si arriva solo a 3000-3600 giri al minuto. Hair dryers with shielded pole induction motors are also known which, however, are unable to guarantee an adequate rotation speed to the air supply fan. A professional hair dryer needs rotation speeds between 13000 and 20000 revolutions per minute, while in the aforementioned appliances it only reaches 3000-3600 revolutions per minute.
Esistono macchine (non asciugacapelli) comandate da un motore ad induzione a poli schermati con invertitore di regolazione associato ad esso. Le velocità di rotazione possono essere di 2 o 3 volte superiore alla velocità nominale ma l’ingombro è tale da non consentirne l’utilizzo in piccoli apparecchi portatili come gli asciugacapelli. There are machines (not hair dryers) controlled by an induction motor with shielded poles with a regulating inverter associated with it. The rotation speeds can be 2 or 3 times higher than the rated speed but the overall dimensions are such that they cannot be used in small portable devices such as hairdryers.
Scopo del presente trovato è quello di realizzare un asciugacapelli efficiente che risolva i problemi sopra menzionati. The object of the present invention is to provide an efficient hairdryer which solves the aforementioned problems.
In accordo con il trovato tale scopo è raggiunto con un asciugacapelli comprendente un involucro che supporta una ventola per il flusso d’aria collegata rotabilmente ad un motore di azionamento, una resistenza elettrica riscaldante ed un interruttore, caratterizzato dal fatto che detto motore è ad induzione a poli schermati ed è previsto in associazione con esso un microinvertitore con dimensioni non superiori a quelle del motore. In accordance with the invention, this object is achieved with a hairdryer comprising a casing which supports a fan for the air flow rotatably connected to an actuation motor, an electric heating resistance and a switch, characterized in that said motor is induction. with shielded poles and a micro-inverter with dimensions not exceeding those of the motor is provided in association with it.
Tale soluzione costruttiva consente dunque di raggiungere velocità comprese tra i 14000 e i 20000 giri al minuto, garantendo silenziosità, durevolezza ed un ottimo impatto ambientale. This constructive solution therefore allows to reach speeds between 14000 and 20,000 revolutions per minute, guaranteeing silence, durability and an excellent environmental impact.
Le caratteristiche ed i vantaggi del presente trovato risulteranno maggiormente evidenti dalla seguente descrizione dettagliata di un suo esempio di realizzazione pratica illustrato a titolo non limitativo nell’unito disegno, in cui: The features and advantages of the present invention will become more evident from the following detailed description of an example of its practical embodiment illustrated by way of non-limiting purposes in the attached drawing, in which:
la figura 1 mostra una vista laterale parziale dell’ asciugacapelli secondo la presente invenzione con l’involucro disegnato in trasparenza. Figure 1 shows a partial side view of the hairdryer according to the present invention with the casing drawn in transparency.
Un asciugacapelli 1 comprende un involucro 2 che supporta un motore elettrico ad induzione a poli schermati 3 a cui è associato un microinvertitore 4, un interruttore manuale 7 ed una resistenza elettrica 8 per il riscaldamento dell’aria. A hairdryer 1 comprises a casing 2 which supports an induction electric motor with shielded poles 3 to which a micro-inverter 4, a manual switch 7 and an electric resistance 8 for heating the air is associated.
L’involucro 2 presenta inoltre una zona di ingresso 9 dell’aria ed una zona di uscita 10 dell’aria. The envelope 2 also has an air inlet area 9 and an air outlet area 10.
Detto motore 3 comanda la rotazione di un alberino 5 a cui è collegata una ventola 6 per il moto dell’ aria. Said motor 3 controls the rotation of a shaft 5 to which a fan 6 is connected for the motion of the air.
Il funzionamento dell’asciugacapelli è piuttosto semplice. The operation of the hairdryer is quite simple.
Azionando Γ interruttore 7 si attiva il motore 3 che comanda la rotazione della ventola 6. By activating switch 7, motor 3 is activated, which controls the rotation of fan 6.
L’aria entra dalla zona di ingresso 9 e fluisce verso la resistenza elettrica 8, attivata anch’essa dall’interruttore 7. La resistenza 8 riscalda l’aria la quale infine esce dall’involucro 2 attraverso la zona di uscita 10 deH’aria. The air enters from the inlet area 9 and flows towards the electrical resistance 8, which is also activated by the switch 7. The resistance 8 heats the air which finally exits the casing 2 through the air outlet area 10 .
Le dimensioni limitate del microinvertitore permettono di ottenere prestazioni elevate (tra i 14000 e i 20000 giri al minuto) in un piccolo apparecchio portatile qual’è un asciugacapelli. The limited size of the micro-inverter allows for high performance (between 14,000 and 20,000 revolutions per minute) in a small portable device such as a hairdryer.
La frequenza di funzionamento è variabile tra i 50 e i 500 Hz e può essere gestita a gradini o tramite potenziometro. The operating frequency is variable between 50 and 500 Hz and can be managed by steps or by means of a potentiometer.
L’assenza di carboni di contatto, tipici dei motori a collettore finora utilizzati per gli asciugacapelli, consente una maggior durata dell’ apparecchio, una maggiore silenziosità ed un miglior impatto ambientale (assenza di particelle di grafite di scarico). The absence of contact carbon, typical of the collector motors used up to now for hair dryers, allows for a longer life of the appliance, greater silence and better environmental impact (absence of exhaust graphite particles).
