This Application is a National Stage of International Application No. PCT/PT2017/050013 filed May 16, 2017, claiming priority based on Portugal Patent Application No. 109389 filed May 16, 2016.
The present invention refers to the field of systems for preparing aromatic beverages by means of extraction of a respective substance, in particular systems with beverage discharge means to the interior of a beverage recipient along a direction that is opposite to the direction of the gravity force.
The present invention further refers to a process of operation of a system for preparing beverages that includes a step of discharge of beverage in a direction opposite the gravity force.
The prior art presents several solutions of beverage discharge in machines for preparing beverages. In particular in the case of aromatic beverages such as for example espresso-like coffee, such beverage discharge is a relevant process with potential impact upon the quality of beverage obtained in the recipient. In fact, in particular in the case of espresso-like coffee, the main characteristics of the discharge flow determines several aspects such as the production of crème and retention thereof inside of the cup, and the variation of temperature as a result of the exposition to air during the discharge into the cup.
The document EP 1991094 B1 discloses a beverage recipient adapted so that can be filled from the base and presenting a sealable base-wall for such purpose, whereby the beverage is injected with a pressure sufficient for opening a valve provided as regulation element for the discharge flow.
The document DE 2009 048233 A1 discloses a similar system whereby portions of edible substance are provided to a collection space by means of raising a lever-like disposition that comprises the beverage discharge means. This solution presents constructive complexity and ergonomic constrains.
The documents EP 2120652 B1 and CH 702947 A2 disclose systems for preparing beverages, including espresso-type coffee, with beverage discharge in a direction opposite to the gravity force and through the support base of the recipient. The document WO 2014/086915 A1 seems to disclose a solution that is similar to those of the aforementioned documents.
The document WO 2014/086915 A1 discloses a similar system whereby there appears to be an opening for introducing a portion of edible substance and beverage discharge provided at a similar height. However, the document does not disclose a compact and ergonomic disposition of said elements.
The documents DE 10 2009 048233 A1 and WO 2015/173127 A2 disclose systems for preparing beverages whereby the flow runs through in a direction opposite to the gravity force inside of a brewing device that collects the edible substance that is the beverage precursor.
The document WO 2015/173128 A1 discloses a similar system for preparing beverages, whereby the beverage discharge means comprise a safety valve actuated by the presence or proximity of a recipient equipped with means for activating said valve, whereby is adapted for selectively opening a fluid communication between the brewing unit and the beverage discharge. This solution leads to increased costs of the beverage recipients. Moreover, this solution does not provide information on a correct placement of the beverage recipient, in particular of a correct alignment and engagement with the beverage discharge means, so that the recipient is not displaced when impinged by the discharge flow. Moreover, the option for restricting the fluid connection at the exit of the brewing unit may lead to a situation whereby the already prepared beverage is retained inside thereof, thereby loosing properties during such period, until a beverage recipient is placed in position.
The document WO 2013/041580 A1 discloses a disposition for support of beverage recipients that is provided so that can support recipients of different dimensions, and including means for removable fixation of said recipients.
None of the prior art documents discloses a solution that provides a system with beverage discharge in a direction opposite the gravity force, and that provides a simples and more compact construction of the machine or apparatus for preparing beverages, as well as simpler and more ergonomic means for confirming the placement of a recipient and the display of information on the operation readiness. There is therefore the need for providing a more efficient and ergonomic system.
The objective of the present invention is to provide a system for preparing beverages including at least one brewing device, in particular of aromatic beverages such as for example espresso-type coffee, adapted for collecting a portion of edible substance, optionally provided inside of a capsule, and a beverage discharge disposition adapted so that provides a simpler, more compact and ergonomic construction.
This objective is attained according to the present invention by means of a system for preparing beverages according to claim 1.
In particular, the aforementioned objective is solved by means of a system comprising an apparatus that presents an opening for introduction of portions of edible substance and a beverage discharge disposition on the same exterior surface, preferentially on an exterior surface of the top part of said apparatus.
It is preferred when said opening of introduction and beverage discharge disposition are provided close, preferentially on a region of the exterior surface presenting an area smaller than three times, preferentially smaller than two times, the sum of the areas individually occupied by said opening of introduction and beverage discharge disposition.
It is preferred when a utilization interface of said apparatus is also provided on the same exterior surface, so that all the manual actions associated with the use of said apparatus, including the placing of a portion, the actuation of the utilization interface and the placement and collection of a beverage recipient, at a similar level and in relative proximity.
It is preferred when said system comprises at least one, preferentially a plurality of types of beverage recipients, including at least one of different dimension and different shape, in particular presenting a general shape of glass, cup or similar type.
A related objective is that of, considering the uncommon arrangement of the beverage discharge disposition, providing simple and ergonomic means for confirming the placement of the recipient and the display of information on the state of readiness for operating said system, so that the user can use it in safe conditions.
In particular, this objective is solved by means of information display means associated with the beverage discharge disposition and provided in functional connection with at least one of a sensor of retention of beverage recipient and a control device of said apparatus for preparing beverages.
Another objective of the present invention is to provide a process for preparing beverages that provides better conditions of beverage discharge flow into a respective beverage recipient.
This objective is solved according to claim 13.
It is preferred when the step of placement of a beverage recipient on said beverage discharge disposition does not include the actuation of said flux regulation device, preferentially a unidirectional valve, provided in the base zone of said beverage recipient.
It is preferred when the step of beverage discharge includes a beverage discharge flow with a flow pressure bigger than 1.1 bar, preferentially a flow pressure bigger than the pressure necessary for displacing upwards an elastic element of said flux regulation device, so as to release at least one passageway of discharge flow to the interior of said beverage recipient.

The expert in the art knows these means so that it is abdicated from a more detailed representation or description thereof.
After brewing the beverage, the beverage discharge flow (BD) is conducted to an exit of said brewing device (2) to a beverage discharge disposition (3) disposed downstream thereof so that the beverage discharge into said beverage recipient (4) flows through said base zone (41) thereof.
According to a first inventive aspect, said introduction opening (8) is provided next to the beverage discharge disposition (3) so that both are accessible on a common exterior surface of the apparatus casing (6) of said beverage preparation apparatus (5), whereby said common exterior surface preferentially corresponds to a single exterior surface on a common plane provided by the top part or by the front part of the apparatus casing (6) of said beverage preparation apparatus (5). In particular, according to the represented preferred embodiment, said beverage discharge disposition (3) is disposed on the top surface and in front of an introduction opening (8) adapted for introduction of a portion (7) of edible substance, on a same exterior surface of the apparatus casing (6) of said beverage preparation apparatus (5). It is herewith advantageously provided a more ergonomic and particularly compact configuration of said beverage preparation apparatus (5).
In the case of the represented preferred embodiment, said beverage discharge disposition (3) is advantageously provided on a more elevated plane relative to said brewing device (2), so that any remaining beverage discharge (BD) falls under the action of the gravity force back to the interior of the beverage discharge disposition (3), preferentially to a lowered collection part (32) that surrounds a respective discharge element (31), as shall be presented further below.
Moreover, in the case of the represented embodiment, the beverage discharge disposition (3) advantageously presents a plurality of discharge elements (31), so that beverage can be supplied simultaneously to two beverage recipients (4).
According to a preferred embodiment, said introduction opening (8) and beverage discharge disposition (3) are provided so that said common exterior surface develops in a single plane and extends beyond, preferentially has at least twice the dimension of the area delimited by said beverage discharge disposition (3) and introduction opening (8), so that advantageously provides an optional support surface for recipients.

In the case of the embodiment represented in
According to another preferred embodiment, the introduction opening (8) and the beverage discharge disposition (3) are provided mobile, so that can be moved outside and inside, between a respective open and closed position, and vice-versa, relative to said exterior surface of the apparatus casing (6), so that when on a respective closed position, the introduction opening (8) and the beverage discharge disposition (3) develop on a single common plane of exterior surface of the beverage preparation apparatus (5).
According to another preferred embodiment, said apparatus (5) presents a height (H) of at most 10 cm, preferentially at most 8 cm, particularly preferred at most 6 cm. In particular, in the case represented, the apparatus (5) can advantageously present means for connection to external fluid reservoirs (not represented), such as for example standard-like bottles of water, so as to ensure a reduced construction height of said apparatus (5).
As one can observe, said apparatus (5) includes a brewing device (2) inside, as well as a respective introduction opening (8) that enables the introduction of said portion (7) of edible substance, and at least one beverage discharge disposition (3).
The system (1) for preparing beverages according to the invention can further include a plurality of types of beverage recipients (4, 4′) presenting different dimension, in particular different dimensions of respective base zones (41), but adapted so as to engage on the same type of beverage discharge disposition (3), in particular presenting similar engaging means with a respective flux regulation disposition (42).
As one can observe, said beverage recipient (4) comprises a base zone (41) including a flux regulation disposition (42) that, in this case, is provided as a plurality of flow passageways (43), provided as micro-holes with a dimension adapted so that the fluid flow only passes through them when under a flow pressure bigger than a previously determined value. In particular, said flow passageways (43) present a characteristic cross dimension, for example a diameter, smaller than 0.5 mm, preferentially smaller than 0.2 mm, so that a liquid only passes through them when injected with a flow pressure bigger than a previously defined flow pressure. Moreover, said flow passageways (43) are provided substantially adjacent to each other, in a mesh-like, honeycomb-like disposition, or similar.
According to an inventive aspect, the beverage recipient (4) further presents a flow deflecting element (45) provided in the proximity downstream from said flux regulation disposition (42) and adapted so that deflects the direction of the beverage discharge flow (BD) and substantially occults the holes associated with said flow passageways (43). It is this ways advantageously provided a discharge of aromatic beverage, such as for example of espresso type coffee, that is more favourable in terms of formation and retention of crème and in terms of less exposition to ambient temperature, thus contributing to enhanced quality in the cup. In fact, the discharge to the interior of a beverage recipient (4) through a respective base zone (41) provides a better distribution of beverage inside thereof, also thereby avoiding the risk of any hot fluid spill outs.
In the case of the embodiment of beverage recipient (4) represented on
According to said inventive aspect, the flux regulation disposition (42) presents a disc-like flow deflecting element (45) connected to said elastic element and adapted so that provides at least one flow passageway (46) when impinged upwards under the action of said elastic element (44), whereby said flow deflecting element (45) is provided so that occults said flux regulation disposition (42) and preferentially presents a similar appearance to the remaining interior surface of the beverage recipient (4).
It is this way provided a simple and economic solution for adapting different types of beverage recipients (4) with the possibility of beverage discharge through a respective base zone (41) in a direction opposite the gravity force.
As represented in
Said flux regulation disposition (42) in this case presents a disc-like flow deflecting element (45) connected to said elastic element and adapted so that presents at least one flow passageway (46) that results unobstructed when said flow deflecting element (45) is impinged upwards under the action of said elastic element (44). As an expert in the field shall readily understand, said flow deflecting element (45) is provided so that can be moved by the action of said elastic element (44) along a previously defined extension in the interior of an opening of the base zone (41), but recovering an initial position of retention in said opening as soon as stops the hydraulic pressure of the beverage discharge flow (BD). According to another preferred embodiment, said flow deflecting element (45) is provided so that substantially occults said flux regulating disposition (42) and that presents a similar appearance to the remaining interior surface of the beverage recipient (4).
As one can further observe in
According to another preferred embodiment, said discharge disposition (3) presents a beverage discharge element (31) that includes at least one flow exit generally oriented upwards, a collection part (32) adapted for collecting the base of beverage recipient (4), and a sealing element (not represented) of type o-ring, or similar, whereby said beverage discharge element (31) is connected with said brewing device (2) by means of a tube, preferentially of flexible type.
Said flux regulation disposition (42) in this case presents at least one, preferentially a plurality of flow passageways (43) oriented upwards on a fixed wall, and an elastic element (44) that is supported on said fixed wall and on an admission part (47) that obstructs the flow passageway when said elastic element (44) is not impinged. When impinged by the beverage discharge flow (BD), said elastic element (44) is displaced upwards, thereby moving said admission part (47) and that way providing (situation represented in the drawing) at least one flow passageway through said flux regulation disposition (42) and to the interior of the collection space (A) of beverage recipient (4).
The beverage recipient (4) further presents a flow deflection element (45) provided fixed, next to and downstream of the flux regulation disposition (42). Alternatively, the flux regulation disposition (42) and the flow deflection element (45) are provided as a single piece whereby an interior and vertically oriented flow passageway leads the flow into a plurality of flow passageways (43) oriented horizontally along the exterior perimeter (embodiment not represented).
It is preferred when said flow deflecting element (45) is an integral part of said beverage recipient (4).
According to another preferred embodiment, said apparatus (5) further comprises state display means (34) adapted so as to communicate to a user the correct placement of the beverage recipient (4) on the beverage discharge disposition (3), whereby said state display means (34) are of at least one type, including of visual and acoustic type, and preferentially provided associated with said beverage discharge disposition (3). Moreover, it is preferred when said state display means (34) are provided so that extend at least in part on said common exterior surface, so that result best visible to the user.
