Description

DESCRIZIONE DESCRIPTION

Il dispositivo in questione appartiene alla numerosa serie dei meccanismi progettati per ottenere caffè espresso in maniera totalmente automatica ;prat icamente tutti questi meccanismi hanno in comune un cilindro oscillante, con all’interno un pistone che provvede alla compressione della polvere e alla sua espulsione, inoltre esiste un contropìstone che si va ad impegnare nel cilindro assicurando la tenuta necessaria per erogare il caffè in pressione. Questo ritrovato, invece, è costituito da una cavità tronco conica (1) inserita in un cassetto che si muove all’ interno di quattro pareti che la guidano mentre compie tutti gli spostamenti necessari a completare il ciclo; nella posizione di partenza A ,la cavità (1) sì trova allineata col contenitore dei caffè in polvere (8) che, grazie ad un minuscolo motoriduttore, provvede a riempirla comprimendo pure il caffè;poi viene spostata in posizione B da un meccanismo ( es. biella-manovella), dove va a corrispondere sul lato inferiore alla caldaia telescopica (4) che fornisce acqua calda necessaria ad ottenere Finiuso e, grazie alia pressione esercitata da una pompa sul fluido,mediante l’ausilio delle guarnizioni (2 e 3), viene sigillata sia rispetto alla caldaia che rispetto alla parete superiore dove si trovano le griglie di inori uscita caffè (5);tale caffè, opportunamente canalizzato, viene portato nella tazzina. The device in question belongs to the numerous series of mechanisms designed to obtain espresso coffee in a totally automatic way; practically all these mechanisms have in common an oscillating cylinder, with a piston inside that provides for the compression of the powder and its expulsion. there is a counter-stone which engages in the cylinder ensuring the necessary seal to deliver the coffee under pressure. This invention, on the other hand, consists of a truncated conical cavity (1) inserted in a drawer that moves inside four walls that guide it while it makes all the movements necessary to complete the cycle; in the starting position A, the cavity (1) is aligned with the powder coffee container (8) which, thanks to a tiny gear motor, fills it by also compressing the coffee; then it is moved to position B by a mechanism (e.g. . connecting rod-crank), where it corresponds on the lower side to the telescopic boiler (4) which supplies hot water necessary to obtain end-use and, thanks to the pressure exerted by a pump on the fluid, with the aid of the gaskets (2 and 3) , is sealed both with respect to the boiler and with respect to the upper wall where the coffee outlet inori grates (5) are located; this coffee, suitably channeled, is brought into the cup.

Terminata l erogazione della bevanda, dopo pochi secondi quando la pressione all’ interno della caldaia si è esaurita,il cassetto può muoversi e raggiungendo la posizione C medi ante l aletta (6), va va ad azionare il bilanciere (7) che spinge verso il basso la carica di caffè esausto, facendola cadere in un apposito contenitore; successivamente si porta in posizione (A) in attesa di ricominciare il ciclo. Nella posizione (A),la flangia (8) consente di inserire, mediante un attacco a baionetta,il contenitore di caffè ; è importante che sia estraibile non solo per poter cambiare agevolmente tipo di cate, ma anche per consentire la pulizia periodica della cavità, La guarnizione sottostante (9) serve ad impedire perdite di caffè durante i movimenti del cassetto.Molteplici sono i vantaggi di questa semplice soluzione e possiamo così riassumerli: Once the beverage has been dispensed, after a few seconds when the pressure inside the boiler is exhausted, the drawer can move and reaching position C between the flap (6), it activates the rocker arm (7) which pushes towards the bottom is filled with exhausted coffee, making it fall into a special container; then it moves to position (A) waiting to restart the cycle. In position (A), the flange (8) allows the coffee container to be inserted by means of a bayonet connection; it is important that it is removable not only to be able to easily change the type of chain, but also to allow periodic cleaning of the cavity, The underlying gasket (9) serves to prevent coffee leaks during the movements of the drawer. solution and we can summarize them as follows:

a) semplicità meccanica a) mechanical simplicity

b) costi di industrializzazione estremamente contenuti b) extremely low industrialization costs

c) vantaggi pratici di funzionamento c) practical advantages of operation

d) riduzione drastica degli ingombri d) drastic reduction of the overall dimensions

e) pulizia,assicurata anche dalla possibilità di lavaggio interno con acqua a 95 gradi (ciclo senza introduzione di caffè). e) cleanliness, also ensured by the possibility of internal washing with water at 95 degrees (cycle without adding coffee).

Claims (4)

RIVENDICAZIONI 1) Sistema automatico per ottenere caffè espresso, costituito da un cassetto con cavità tronco conica che può muoversi avanti e indietro, compiendo in una sola oscillazione le fasi di carico della polvere - erogazione caffè - espulsione - ritorno. CLAIMS 1) Automatic system for obtaining espresso coffee, consisting of a drawer with a truncated cone cavity that can move back and forth, performing the powder loading - coffee dispensing - ejection - return phases in a single oscillation. 2) Caldaia telescopica, che consente di sigillare, grazie alla guarnizione(2) solidale alla caldaia e alla guarnizione (3) solidale al cassetto, la cavità tronco conica contenente la polvere di caffè durante l'erogazione della bevanda. 2) Telescopic boiler, which allows to seal, thanks to the gasket (2) integral with the boiler and the gasket (3) integral with the drawer, the truncated cone cavity containing the coffee powder during the dispensing of the drink. 3) Flangia per il contenitore della polvere di caffè munito di attacco rapido di sganciamento e dì guarnizione di tenuta inferiore per garantire la tenuta. 3) Flange for the container of coffee powder equipped with quick release coupling and lower seal gasket to guarantee the seal. 4) Espulsione della carica di caffè esausta mediante sistema a bilanciere azionato dal movimento del cassetto.4) Ejection of the exhausted coffee charge by means of a rocker system activated by the movement of the drawer.
