DESCRIZIONE DESCRIPTION
di una domanda di brevetto per Invenzione Industriale avente titolo: of a patent application for an Industrial Invention entitled:
“Elettrodomestico” "Appliance"
CAMPO DELL’INVENZIONE FIELD OF THE INVENTION
Il presente trovato è relativo a un elettrodomestico. The present invention relates to a household appliance.
In particolare, si riferisce a un forno che presenta una porta che, quando è aperta, scompare in un alloggiamento posto nella parte bassa del forno. In particular, it refers to an oven that has a door which, when open, disappears into a housing located in the lower part of the oven.
STATO DELLA TECNICA STATE OF THE TECHNIQUE
Le porte di elettrodomestici tradizionali si aprono ruotando lungo un asse di incernieramento che può essere orizzontale o verticale. The doors of traditional household appliances are opened by rotating along a hinging axis which can be horizontal or vertical.
In posizione di apertura, quindi, esse sporgono frontalmente rispetto all’elettrodomestico e obbligano l’utilizzatore ad allungarsi per accedere, ad esempio, al vano riscaldante di un forno o ad un vano di un altro elettrodomestico, limitando così l’accessibilità dello stesso. In the open position, therefore, they protrude from the front with respect to the appliance and force the user to reach out to access, for example, the heating compartment of an oven or a compartment of another appliance, thus limiting its accessibility.
RIASSUNTO DELL’INVENZIONE SUMMARY OF THE INVENTION
Scopo del presente trovato è quello di fornire un elettrodomestico perfezionato rispetto alla tecnica nota. The object of the present invention is to provide an improved household appliance with respect to the known art.

DESCRIZIONE DETTAGLIATA DELL’INVENZIONE DETAILED DESCRIPTION OF THE INVENTION
Con riferimento alle figure citate viene mostrato un elettrodomestico indicato complessivamente con il numero di riferimento 1. With reference to the aforementioned figures, a household appliance indicated as a whole with the reference number 1 is shown.
L’elettrodomestico è solo schematicamente rappresentato nella figura 6, ma sostanzialmente esso comprende una struttura The appliance is only schematically represented in figure 6, but substantially it comprises a structure
3A che supporta tutte le parti dell’elettrodomestico utili al suo funzionamento. 3A which supports all parts of the appliance useful for its operation.
Nello specifico, l’elettrodomestico di figura 6 può essere un forno, che è dotato di una porta o anta a scomparsa. Specifically, the appliance in figure 6 can be an oven, which is equipped with a retractable door or door.
L’anta 3 comprende un elemento di guida 30, che può essere ad esempio un perno, o un perno su cui è montato un rullo girevole, che risulta scorrevole in una prima guida 31 vincolata alla struttura 3A dell’elettrodomestico 1. The door 3 includes a guide element 30, which can be for example a pin, or a pin on which a rotating roller is mounted, which slides in a first guide 31 attached to the structure 3A of the appliance 1.
L’anta 3A comprende inoltre una seconda guida 32 all’interno della quale è scorrevolmente impegnato uno snodo 6 di una prima cerniera 5. The door 3A also includes a second guide 32 inside which a joint 6 of a first hinge 5 is slidingly engaged.
Ad esempio, lo snodo 6 è impegnato nella seconda guida 32 tramite almeno una, ma preferibilmente due, rotelle 33 rotabilmente vincolate allo snodo 6 stesso. For example, the joint 6 is engaged in the second guide 32 by means of at least one, but preferably two, rollers 33 rotatably constrained to the joint 6 itself.
Nelle figure dalla 6 alla 8, l’elettrodomestico è rappresentato (solo schematicamente) in vista laterale, quindi è visibile solo un lato dell’anta. L’altro lato dell’anta può presentare tuttavia delle strutture analoghe a quelle sopra descritte e un ulteriore cerniera 5 identica, o molto simile, a quella che verrà qui descritta in dettaglio. In figures 6 to 8, the appliance is represented (only schematically) in side view, so only one side of the door is visible. However, the other side of the door may have structures similar to those described above and a further hinge 5 identical, or very similar, to the one that will be described in detail here.
La prima cerniera 5 comprende un telaio 7 fissato in modo convenzionale alla struttura 3A dell’elettrodomestico. The first hinge 5 comprises a frame 7 fixed in a conventional way to the structure 3A of the appliance.
Il telaio può essere realizzato tramite un unico pezzo di lamiera sagomato e ripiegato a U. Le porzioni affacciate del telaio (spalle) possono essere mantenute a debita distanza da rivetti 90. Nel telaio possono essere realizzate piegature di rinforzo 80, per irrobustire opportunamente la struttura. The frame can be made by means of a single piece of shaped and U-folded sheet metal. The facing portions of the frame (shoulders) can be kept at a safe distance from rivets 90. Reinforcement folds 80 can be made in the frame, to appropriately strengthen the structure .
Anche i perni P1, P4, P5 di incernieramento delle varie parti della cerniera che verranno descritte tra poco, possono assolvere alla doppia funzione di incernierare le varie parti della cerniera e al contempo fungere da distanziali. Tali perni possono essere ribattuti, o bloccati in altro modo. Also the hinging pins P1, P4, P5 of the various parts of the hinge which will be described shortly, can perform the double function of hinging the various parts of the hinge and at the same time acting as spacers. These pins can be riveted, or locked in any other way.
Lo snodo 6 e il telaio 7, ad esempio, sono reciprocamente incernierati in un primo punto A, da un perno P1. The joint 6 and the frame 7, for example, are reciprocally hinged at a first point A, by a pin P1.
Lo snodo 6 è altresì incernierato da un perno P2 in un suo secondo punto B che può essere distante dal primo punto A, ad un tirante 8 caricato da un elemento elastico 9 vincolato al telaio 7. The joint 6 is also hinged by a pin P2 in its second point B which can be distant from the first point A, to a tie rod 8 loaded by an elastic element 9 bound to the frame 7.
Nell’esempio, l’elemento elastico 9 è una molla a trazione. Il punto D di incernieramento tra tirante 8 e molla è semplicemente un perno P3 del tirante, su cui è calzato un gancio della molla. In the example, the elastic element 9 is a traction spring. The hinging point D between the tie rod 8 and the spring is simply a pin P3 of the tie rod, on which a spring hook is fitted.
Vantaggiosamente il tirante 8 è realizzato per piegatura a U di una lamiera metallica, che può anch’essa prevedere piegature di rinforzo 90. I perni P2 e P3 possono fungere anche da distanziali per mantenere la ‘forma’ del tirante. Advantageously, the tie rod 8 is made by U-shaped bending of a metal sheet, which can also provide reinforcement folds 90. The pins P2 and P3 can also act as spacers to maintain the 'shape' of the tie rod.
La configurazione del tirante (in sezione) a U, permette di realizzare un agevole incernieramento anche allo snodo 6, proprio tramite il perno P2. Di fatto le spalle del tirante sono calzate sullo snodo e il perno P2 viene ribattuto nei fori del tirante facendolo passare per il foro dello snodo 6 in corrispondenza del quale avviene l’incernieramento B. The U-shaped configuration of the tie rod (in section) allows to realize an easy hinging also to the joint 6, through the pin P2. In fact, the shoulders of the tie rod are fitted on the joint and the pin P2 is riveted into the holes of the tie rod by passing it through the hole in the joint 6 at which hinging B takes place.
La forma a U del tirante 8 definisce anche un vano che permette di alloggiare almeno alcune parti dello snodo 6 quando si trova in predeterminate posizioni angolari (si veda ad esempio la figura 5), e vantaggiosamente in modo da alloggiare il braccio 16 che supporta il rullo 14 (che verrà descritto in seguito). The U-shape of the tie rod 8 also defines a compartment which allows to house at least some parts of the joint 6 when it is in predetermined angular positions (see for example Figure 5), and advantageously so as to house the arm 16 which supports the roller 14 (which will be described later).
La molla 9, può essere agganciata a un terzo punto C del telaio, ad esempio formato da un perno P4. Anche in questo caso un gancio della molla è semplicemente calzato sul perno P4. The spring 9 can be hooked to a third point C of the frame, for example formed by a pin P4. Also in this case a spring hook is simply fitted on the P4 pin.
Come si vede dalla figura 1, la cerniera 5 comprende inoltre uno smorzatore 10 configurato per frenare l’anta almeno in prossimità di una posizione di chiusura dell’anta 3 stessa. As can be seen from figure 1, the hinge 5 also comprises a damper 10 configured to brake the door at least in the vicinity of a closing position of the door 3 itself.
Lo smorzatore è ad esempio di tipo idraulico, con molla di riarmo. The damper is, for example, of the hydraulic type, with a reset spring.
Lo smorzatore 10 può essere fissato al telaio 7, e può cooperare con il tirante 8 per frenare l’anta 3, in prossimità di una posizione di chiusura. The damper 10 can be fixed to the frame 7, and can cooperate with the tie rod 8 to brake the wing 3, near a closing position.
Ad esempio un corpo 10B dello lo smorzatore 10 può essere stabilmente fissato al telaio tramite rivetti 90. For example, a body 10B of the damper 10 can be stably fixed to the frame by means of rivets 90.
In tale configurazione, lo smorzatore 10 prevede uno stelo mobile 10A che può coopera con un perno mobile 11 scorrevolmente impegnato in una prima asola 12 del telaio 7. In this configuration, the damper 10 provides a movable stem 10A which can cooperate with a movable pin 11 slidingly engaged in a first slot 12 of the frame 7.
La prima asola 12 può presentare un asse longitudinale L parallelo o sovrapposto (o coincidente, almeno in vista laterale) con l’asse dello stelo mobile 10A. The first slot 12 can have a longitudinal axis L parallel or superimposed (or coincident, at least in lateral view) with the axis of the mobile stem 10A.
Il tirante 8 comprende una porzione a culla 8A configurata per ingaggiare (e alloggiare) parzialmente il perno mobile 11, quando l’anta è in fase di frenatura. The tie rod 8 comprises a cradle-shaped portion 8A configured to partially engage (and house) the mobile pin 11, when the leaf is in the braking phase.
La porzione a culla 8A può assumere una configurazione semicircolare. The cradle portion 8A can assume a semicircular configuration.
La culla 8A può essere prevista sul tirante 8 in una posizione disassata rispetto all’asse che congiunge detto secondo punto B e detto terzo punto C. The cradle 8A can be provided on the tie rod 8 in an offset position with respect to the axis that connects said second point B and said third point C.
Vantaggiosamente il tirante presenta quindi una forma a L (in vista laterale). Advantageously, the tie rod therefore has an L-shape (in side view).
Per mantenere una salda posizione di chiusura (spesso è utile che la porta venga ‘forzata’ in posizione di chiusura, ad esempio per comprimere eventuali guarnizioni) lo snodo 6 può prevede una superficie a camma 6A su cui è scorrevole un rullo 14 caricato da una ulteriore molla 15. To maintain a firm closing position (it is often useful for the door to be 'forced' into the closed position, for example to compress any gaskets) the joint 6 can provide a cam surface 6A on which a roller 14 loaded by a additional spring 15.
Dunque, la camma 6A e il rullo 14 cooperando per caricare l’anta 3 in posizione di chiusura. Therefore, the cam 6A and the roller 14 cooperating to load the leaf 3 in the closed position.
L’ulteriore molla 15 si estende tra il telaio 7 (o una parte di esso opportunamente ripiegata) e il rullo 14. The further spring 15 extends between the frame 7 (or a part of it suitably folded) and the roller 14.
Ad esempio, il rullo 14 può essere posizionato su di un braccio 16 incernierato in un quarto punto 19 al telaio 7. In questo caso, il braccio il rullo e la molla formano un complesso denominato ‘pendolo’. For example, the roller 14 can be positioned on an arm 16 hinged at a fourth point 19 to the frame 7. In this case, the arm, the roller and the spring form a complex called 'pendulum'.
L’ulteriore molla dunque provvede a caricare il braccio, e di conseguenza il rullo, spingendolo contro la camma dello snodo. The additional spring therefore loads the arm, and consequently the roller, pushing it against the cam of the joint.
C’è da dire che il rullo può risultare a contatto con la camma solo in alcune posizioni della cerniera, prossime a quella in cui la porta o anta 3 è chiusa. It must be said that the roller may be in contact with the cam only in some positions of the hinge, close to that in which the door or leaf 3 is closed.
Il funzionamento del trovato è evidente da quanto descritto, ed è sostanzialmente il seguente. The operation of the invention is evident from what has been described, and is substantially the following.
Preliminarmente si fa notare che nella figura 1, sono indicate delle linee tratteggiate che mostrano come la cerniera viene assemblata. Preliminarily it should be noted that in figure 1, dashed lines are indicated that show how the hinge is assembled.
Inoltre, tutte le figure dalla 2 alla 5 sono estremamente semplificate e mostrano la cerniera con una parte (una spalla) del telaio 7 rimossa in modo da rendere visibili le posizioni reciproche delle varie parti della cerniera, quando lo snodo assume angoli diversi. Furthermore, all figures 2 to 5 are extremely simplified and show the hinge with a part (a shoulder) of the frame 7 removed so as to make visible the mutual positions of the various parts of the hinge, when the joint assumes different angles.
Nella figura 5 è mostrata la cerniera 5 in posizione di completa apertura, ovvero con lo snodo angolato di 90° (porta Figure 5 shows the hinge 5 in the fully open position, i.e. with the joint angled at 90 ° (door
aperta di figura 8). Si nota che la culla 8A del tirante è molto distanziata rispetto al primo perno 11, che è alloggiato scorrevolmente nell’asola 12. In questa configurazione il perno 11 può essere libero di scorrere nell’asola e non risulta pressato dallo stelo dello smorzatore. open in figure 8). It is noted that the cradle 8A of the tie rod is far apart from the first pin 11, which is slidably housed in the slot 12. In this configuration, the pin 11 can be free to slide in the slot and is not pressed by the damper stem.
Una rotazione in chiusura dello snodo 6 porta la cerniera (e quindi l’anta 3) nella condizione di figura 4. Tale configurazione è quella immediatamente precedente ad un intervento dello smorzatore, nel moto di chiusura dell’anta 3 stessa. A closing rotation of the joint 6 brings the hinge (and therefore the door 3) to the condition of figure 4. This configuration is the one immediately preceding an intervention of the damper, in the closing motion of the door 3 itself.
Si vede infatti che la culla 8A risulta in appoggio sul perno 11 e inizia a spingerlo verso lo stelo 10A dello smorzatore, che tuttavia non è ancora in contatto con il primo perno 11. In fact, it can be seen that the cradle 8A rests on the pin 11 and begins to push it towards the stem 10A of the damper, which however is not yet in contact with the first pin 11.
Un ulteriore movimento in chiusura dello snodo 6, che avviene a causa della molla 9, che agisce sul tirante 8, spinge il perno 11 a contatto con lo smorzatore, che inizia quindi il suo intervento nel frenare la chiusura dell’anta. A further closing movement of the joint 6, which occurs due to the spring 9, which acts on the tie rod 8, pushes the pin 11 into contact with the damper, which then begins its intervention in braking the closing of the door.
La figura 3 mostra lo smorzatore 10 circa a metà della sua corsa di lavoro. In tale configurazione il rallentamento imposto allo snodo 6 (e quindi all’anta 3) è molto intenso. Figure 3 shows the damper 10 about halfway through its working stroke. In this configuration, the slowdown imposed on joint 6 (and therefore on leaf 3) is very intense.
Il movimento in chiusura prosegue fino alla posizione di figura 2. In queste condizioni il perno 11 è a fondo corsa dell’asola 12. The closing movement continues up to the position of figure 2. In these conditions, the pin 11 is at the end of the stroke of the slot 12.
Si noti, che nel passaggio dalla figura 4 alla figura 3 e quindi alla 2 (quindi in chiusura), il rullo 14 supera una ‘cresta’ presente sulla camma 6A, spingendo quindi lo snodo, e quindi l’anta 3, in posizione di chiusura. It should be noted that in the passage from figure 4 to figure 3 and then to 2 (therefore closing), the roller 14 overcomes a 'ridge' present on the cam 6A, thus pushing the joint, and therefore the wing 3, into the position of closure.
Ad esempio, per comprimere delle guarnizioni di tenuta, eventualmente presenti nell’elettrodomestico (si pensi ad esempio a quelle della porta di un forno, o di una lavastoviglie). For example, to compress the sealing gaskets, possibly present in the appliance (think for example of those on the door of an oven, or a dishwasher).
Si noti che, quanto il movimento dell’anta 3 è in apertura, lo snodo si distanzia dal primo perno 11, e lo smorzatore 10 può ri-armarsi autonomamente. Note that, when the movement of the leaf 3 is opening, the joint distances itself from the first pin 11, and the damper 10 can be re-armed autonomously.
Sono state descritte varie forme di realizzazione dell’innovazione, ma altre potranno essere concepite sfruttando lo stesso concetto innovativo. Various embodiments of the innovation have been described, but others may be conceived using the same innovative concept.
