La presente invención se refiere a un dispositivo de doble molienda que ha sido especialmente concebido para poder ser implantado en cafeteras italianas como un elemento accesorio adicional a las mismas, que no afecta a su funcionamiento en lo que respecta al proceso de infusionado, pero que sin embargo permite la aplicación directa de granos enteros de café en la propia cafetera.The present invention refers to a double grinding device that has been specially conceived to be able to be implanted in Italian coffee machines as an additional accessory element to them, which does not affect its operation with regard to the infusion process, but without However, it allows the direct application of whole coffee beans in the coffee maker itself.
El objeto de la invención es por tanto proporcionar un dispositivo que incremente las prestaciones habituales de este tipo de cafeteras italianas permitiendo el uso indistinto de café molido o que el usuario pueda moler el propio café que estime conveniente, mediante un dispositivo que apenas ocupa espacio, ya que se integra en el propio cuerpo de la cafetera, todo ello en base a una estructura sencilla pero sumamente eficaz.The object of the invention is therefore to provide a device that increases the usual features of this type of Italian coffee machine, allowing the indistinct use of ground coffee or that the user can grind the coffee that he deems convenient, by means of a device that hardly takes up space, since it is integrated into the body of the coffee maker itself, all based on a simple but highly effective structure.
El dispositivo de la invención puede industrializarse de forma independiente, o bien como elemento adicional del tipo de cafeteras anteriormente referidas, así como vincularse a cafeteras específicamente diseñadas para este tipo de dispositivo.The device of the invention can be industrialized independently, or as an additional element of the type of coffee machines referred to above, as well as linked to coffee machines specifically designed for this type of device.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En el ámbito de aplicación práctica de la invención, el de las máquinas para la elaboración de café, las cafeteras de tipo italiano o moka tienen una gran aceptación en virtud de su sencillez estructural, durabilidad y facilidad de mantenimiento.In the field of practical application of the invention, that of machines for making coffee, Italian or Moka type coffee pots are widely accepted by virtue of their structural simplicity, durability and ease of maintenance.
De forma más concreta, este tipo de cafeteras se constituyen a partir de un depósito de agua, sobre el que se inserta un depósito de café a infusionar, en este caso de café molido, con una chimenea inferior a través de la que asciende el vapor de agua al ser ésta calentada, atravesando e infusionándose con el café molido, accediendo a través de una segunda chimenea el café ya hacia un depósito de café infusionado superior, previo paso a través del correspondiente filtro, incluyendo la cafetera una o mas juntas de estanqueidad.More specifically, this type of coffee maker is made up of a water tank, on which is inserted a tank of coffee to be infused, in this case ground coffee, with a lower chimney through which the steam rises. of water as it is heated, passing through and infusing with the ground coffee, accessing through a second chimney, the coffee already goes to an upper infused coffee tank, after passing through the corresponding filter, the coffee maker including one or more sealing gaskets.
Se trata pues de un accesorio estructuralmente muy sencillo, en el que las diferentes piezas que participan en el mismo se vinculan la mayoría de ellas mecánicamente mediante encaje entre las mismas, de modo que el único mecanismo de accionamiento que requiere la cafetera es el roscado del depósito de café infusionado a través de su extremidad inferior sobre el cuello roscado que incluye superiormente el depósito de agua.It is therefore a structurally very simple accessory, in which the different parts that participate in it are linked, most of them mechanically by fitting together, so that the only drive mechanism that the coffee maker requires is the threading of the infused coffee tank through its lower end on the threaded neck that includes the water tank on top.
Así pues, y como se ha dicho con anterioridad, este tipo de cafeteras solo permiten obtener infusiones de café a partir de café molido, no siendo funcionales a la hora de partir de granos de café sin moler, lo que requiere el uso complementario de molinillos de café, lo que supone un problema de espacio, así como de dependencia entre dispositivos, a lo que hay que añadir, la pérdida de tiempo y complejidad en el proceso de traslación y vertido del café una vez molido desde un dispositivo a otro.Thus, and as has been said before, this type of coffee machine only allows coffee infusions to be obtained from ground coffee, not being functional when starting from unground coffee beans, which requires the additional use of grinders. of coffee, which supposes a problem of space, as well as of dependency between devices, to which must be added, the loss of time and complexity in the process of transferring and pouring the coffee once ground from one device to another.
Tratando de obviar esta problemática se conocen cafeteras que ya incluyen un mecanismo de molido de los granos del café en el propio seno de la cafetera.Trying to avoid this problem, coffee machines are known that already include a mechanism for grinding the coffee beans within the coffee machine itself.
Este es el caso de la patente de invención WO 2007070874-A2.This is the case of the invention patent WO 2007070874-A2.
El problema que presenta este dispositivo es que se integra en un modelo de cafetera no convencional, como elemento integrado en la propia cafetera y por lo tanto inseparable de la misma, no siendo aplicable a cafeteras italianas convencionales, cuyo uso está ampliamente extendido.The problem with this device is that it is integrated into a non-conventional coffee maker model, as an element integrated into the coffee maker itself and therefore inseparable from it, not being applicable to conventional Italian coffee makers, whose use is widely extended.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
El dispositivo de doble molienda para cafeteras italianas que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero eficaz, pudiendo adaptarse a cualquier cafetera de tipo italiana o moka existente en el mercado, así como formar parte de ésta en caso de que se quiera comercializar de forma conjunta, o bien aplicarse sobre cafeteras de nuevo diseño específico para este tipo de dispositivo con unos cambios estructurales mínimos.The recommended double grinding device for Italian coffee machines fully satisfactorily solves the aforementioned problems, based on a simple but effective solution, which can be adapted to any existing Italian or Moka coffee machine on the market, as well as being part of this one in case you want be marketed together, or applied to coffee machines with a new specific design for this type of device with minimal structural changes.
Para ello, el dispositivo de la invención se constituye a partir de dos módulos que se adaptan, respectivamente, de forma directa, al depósito de café infusionado, así como a la al depósito de agua de una cafetera italiana o moka, de modo que el mismo quede perfectamente integrado en la estructura de la cafetera, incrementando ligeramente su altura, de modo que dichos módulos definen unos medios de doble molienda de granos de café sin interferir en el normal funcionamiento de la cafetera cuando se calienta el agua hasta el punto de ebullición en el seno de su depósito de agua.For this, the device of the invention is constituted from two modules that adapt, respectively, directly, to the infused coffee tank, as well as to the water tank of an Italian or moka coffee maker, so that the It is perfectly integrated into the structure of the coffee maker, slightly increasing its height, so that said modules define means for double grinding coffee beans without interfering with the normal operation of the coffee maker when the water is heated to the boiling point. inside your water tank.
Estos módulos pueden incluir roscas complementarias a las de los depósitos de la cafetera anteriormente citados, o bien incluir medios de acoplamiento complementarios, en caso de cafeteras de nuevo diseño, en las que habría que rediseñar estos medios de acoplamiento, manteniendo por lo demás su estructura convencional.These modules may include complementary threads to those of the previously mentioned coffee maker tanks, or include complementary coupling means, in the case of newly designed coffee machines, in which these coupling means would have to be redesigned, otherwise maintaining its structure. conventional.
De forma más concreta, el módulo inferior presenta una configuración a modo de cazoleta en el que se establece un cuello central hueco a modo de chimenea, alineado verticalmente con el clásico cuello de salida del café infusionado del depósito superior de café infusionado, cuello sobre cuya cara externa se distribuyen una serie de muelas o dientes de distintos tamaños para reducir progresivamente la granulometría de la molienda de los granos de café, estableciéndose en su base o fondo un cedazo a través del que se deja pasar el café molido hacia el depósito de café molido convencional en este tipo de cafeteras, y que quedará dispuesto inmediatamente por debajo de dicho módulo inferior.More specifically, the lower module has a bowl-like configuration in which a hollow central neck is established as a chimney, vertically aligned with the classic infused coffee outlet neck of the upper infused coffee tank, neck on whose external face a series of wheels or teeth of different sizes are distributed to progressively reduce the granulometry of the grinding of the coffee beans, establishing a sieve at its base or bottom through which the ground coffee is allowed to pass towards the coffee tank conventional ground in this type of coffee maker, and which will be arranged immediately below said lower module.
Así pues, y como se ha dicho con anterioridad, el módulo inferior se roscará al clásico cuello roscado que incluye el depósito de agua de este tipo de cafeteras por medio de un roscado complementario.Thus, and as has been said before, the lower module will be threaded to the classic threaded neck that includes the water tank of this type of coffee machine by means of a complementary thread.
En la zona superior del citado módulo inferior se establecerá un cuello roscado interiormente.An internally threaded neck will be established in the upper area of said lower module.
Por su parte, el módulo superior presentará un cuello inferior roscado exteriormente, de diámetro acorde al diámetro interno del módulo inferior en el que se inserta, a través del que se vinculan ambos módulos, siendo este roscado complementario el que permite el giro relativo entre ambos módulos y la aproximación o alejamiento entre los mismos, durante las maniobras de doble molienda.For its part, the upper module will present an externally threaded lower neck, with a diameter according to the internal diameter of the lower module in which it is inserted, through the that both modules are linked, this complementary threading being the one that allows the relative rotation between both modules and the approach or distance between them, during the double grinding maneuvers.
Para ello, dicho módulo superior presenta un cuerpo a modo de cazoleta con un sector tronco cónico en su zona intermedia, afectado de ventanas para paso de los granos de café a la zona de confluencia entre ambos módulos, siendo abierto en correspondencia con dicha base del tronco de cono, de modo que dicho módulo superior está destinado a recibir los granos de café enteros, accediendo éstos a través de las comentadas ventanas hacia la zona de molienda, contando dicho módulo superior en correspondencia con el borde de la base del cono con unas muelas o dentados internos complementarios de los dentados de la chimenea del módulo inferior, a través de los que se lleva a cabo una primera fase de molienda, incluyendo igualmente unos dientes o muelas de menor tamaño en correspondencia con su base inferior plana a través de los que se lleva a cabo la segunda molienda, base destina a entrar en contacto contra el cedazo del módulo inferior.To do this, said upper module has a bowl-like body with a frustoconical sector in its intermediate area, affected by windows for the passage of coffee beans to the confluence area between both modules, being opened in correspondence with said base of the module. truncated cone, so that said upper module is intended to receive the whole coffee beans, accessing them through the aforementioned windows towards the grinding zone, counting said upper module in correspondence with the edge of the base of the cone with some internal grinding wheels or teeth complementary to the chimney teeth of the lower module, through which a first grinding phase is carried out, also including smaller teeth or wheels in correspondence with its lower flat base through the that the second grinding is carried out, the base is intended to come into contact with the sieve of the lower module.
El módulo superior así descrito incluirá un roscado superior y exterior complementario del clásico roscado interior e inferior que incluye el depósito de café infusionado de este tipo de cafeteras.The upper module described in this way will include an upper and external thread complementary to the classic internal and lower thread that includes the infused coffee tank of this type of coffee machine.
El citado sector tronco cónico incluirá en correspondencia con su base superior unas aberturas que quedan enfrentadas tanto a la chimenea del módulo inferior como a la chimenea del depósito de café (con interposición del clásico filtro), de modo que el dispositivo no afecte (o afecte mínimamente) al funcionamiento habitual de este tipo de cafeteras una vez el café molido haya accedido al depósito de café molido.The aforementioned frustoconical sector will include openings in correspondence with its upper base that face both the chimney of the lower module and the chimney of the coffee tank (with the classic filter interposed), so that the device does not affect (or affects minimally) to the normal operation of this type of coffee maker once the ground coffee has entered the ground coffee tank.
La estructura así descrita se puede complementar con una o varias juntas de estanqueidad anulares entre los diferentes elementos que roscan entre sí, preferentemente dos.The structure thus described can be complemented with one or more annular sealing joints between the different elements that screw together, preferably two.
A partir de esta estructuración, y al poder sujetarse el dispositivo tanto por su módulo superior como por su módulo inferior, éste podrá acoplarse y desacoplarse al depósito de café infusionado, para rellenar el módulo superior de granos de café, así como acoplarse y desacoplarse del depósito de agua para rellenar este de agua y vaciar el depósito de café molido una vez infusionado, de forma rápida, cómoda y sencilla. Based on this structuring, and as the device can be held both by its upper module and by its lower module, it can be coupled and uncoupled from the infused coffee tank, to fill the upper module with coffee beans, as well as coupled and uncoupled from the water tank to fill this with water and empty the tank of ground coffee once infused, quickly, conveniently and easily.
En tal sentido, y como ya se ha dicho con anterioridad, no se descarta que el módulo superior y el módulo inferior se acoplen y desacoplen respectivamente al depósito de café infusionado y al depósito de agua mediante otros tipos de mecanismos de acoplamiento, como por ejemplo mediante tetones acoplables a ranuras complementarias, sin que ello afecte a la esencia de la invención, si bien dichos medios deben afectar por tanto a la cafetera italiana, cuyo diseño habría que reestructurar ligeramente sin verse afectada su funcionalidad.In this sense, and as has been said previously, it is not ruled out that the upper module and the lower module are coupled and uncoupled respectively to the infused coffee tank and the water tank by means of other types of coupling mechanisms, such as for example by means of lugs that can be coupled to complementary slots, without affecting the essence of the invention, although said means must therefore affect the Italian coffee maker, whose design would have to be slightly restructured without affecting its functionality.
