The expert in the field knows these means such that one herewith abdicates from a more detailed representation or description thereof.
Moreover, said apparatus (10) presents a beverage preparation device (3), provided so that can collect said individual portion (7), and impinge the latter with said pressurized flow (FS) so that mixes with the edible substance and a beverage results therefrom. Said beverage preparation device (3) can be actuated between open and closed positions, and vice-versa, by means of an actuation device (4), referred to as motor in the drawings. The individual portion (7) can be supplied to the beverage preparation device (3) by insertion thereof into a respective portion inlet (6). An access disposition (5) configured as actionable lid-like element, can enable access to the portion inlet (6). Other possibilities of supplying individual portions (7) are not excluded from the scope of the present invention.
After preparing the beverage, the beverage discharge flow (BD) is conducted from an exit of said beverage preparation device (3) to a beverage discharge disposition (2) arranged downstream thereof, and presenting injection means (23) so that the beverage discharge to the interior of said drinking recipient (1) unfolds through a base zone thereof.
In the case of this embodiment, the apparatus (10) further presents an access disposition (5) adapted so that can be moved between a first and second position where provides access to the beverage discharge disposition (2) for placing the drinking recipient (1), and vice-versa.
The apparatus (10) further comprises control means (9) adapted so that can control the operation of the flow pressurization (8) and beverage preparation device (3), as well as of several other components of the apparatus (10), including of said actuation device (4) and access disposition (5), and the display of information to the user.
In particular, said control means (9) (also referred to in the drawings as control device), are adapted so that can apprehend data from of a plurality of operating parameters, including: data relating to the position of the access disposition (5), to the correct placement of drinking recipient (1) on said beverage discharge disposition (2), to the presence of individual portion (7) on said apparatus (10), as well as to the position of said actuation device (4), in particular on the edges of the displacement path, thereby inferring the corresponding position of the beverage preparation device (3), in particular completely closed and open.
In particular, according to an aspect of the present invention, in view of the regulation of correct handling of the drinking recipient (1) and individual portion (7) in each cycle, the control means (9) operate based upon the assessment of conditional relations associated with:
The apparatus (10) can herewith detect eventual handling mistakes, trigger corrective measures thereof, and display respective information to a user.
It is preferred when the actuation device is a DC electric motor.
In particular, according to another aspect of the present invention, said control means (9) are adapted so that, in each operation cycle, can automatically command: the fluid injection by said flow pressurization device (8), and the opening and closing of said beverage preparation device (3), as a function of the detection of respective control events, preferentially by means of detection sensors (21, 22; 31, 32; 41, 42), and without requiring a specific intervention, interaction or actuation by the user, whereby at least one of said control events is preferentially associated with the manipulation of the drinking recipient (1) on said beverage discharge disposition (2). It is herewith advantageously provided that said apparatus (10) can be devoid of user interfaces specific for actuation of beginning and end of operation cycle, and for opening and closing of said beverage preparation device (3).
It is preferred when said handling alignment (A) extends around the drinking recipient (1), in particular so that said first recipient sensor (21) can be actuated by means of rotation of the drinking recipient (1) around a vertical axis (X) thereof, between a first (I) and a second position (II), thereby apprehending the respective relative displacement.
It is preferred when a first recipient sensor (21) is associated with an initial retention position of the drinking recipient (1) on the beverage discharge disposition (2). In a preferred embodiment, said first recipient sensor (21) is adapted so that can apprehend said initial retention position of the recipient, and associated with a first direction of the handling alignment (A) so that can further apprehend a relative dimension of displacement of the drinking recipient (1) there along, whereby said relative dimension of displacement can be associated by said control means (9) to a corresponding quantity of beverage to be discharged in each cycle.
The beverage discharge disposition (2) can present a second handling alignment (B), for example associated with a different type of beverage discharge, or to a second type of beverage, such as for example tea. In this case there can be further provided a second recipient sensor (22) associated with said second handling alignment (B).
Said beverage preparation apparatus (10) can further comprise sensors (41, 42) of beginning and end of path of the actuation device (4), whereby both said sensors of beginning and end of path are preferentially of switch type actuated by mechanical contact, adapted so that can be actuated by contact, in particular by the mobile part of the actuation device (4), and so that respective actuation data are communicated to said control means (9).
Said beverage preparation apparatus (10) can further comprise portion detection means (31, 32) adapted so that can be actuated by said individual portion (7) in at least one of: inside of said beverage preparation device (3), upstream (A) and downstream (B) of said beverage preparation device (3).
Said apparatus (10) can comprise first (31) and second (32) portion sensors, arranged respectively upstream and downstream of said beverage preparation device (3), whereby both said portion sensors (31, 32) are preferentially of the switch type actuated by mechanical contact, adapted so that can be actuated by contact, in particular by the passage of the individual portion (7), and so that respective actuation data are communicated to said control means (9).
It is thus preferred when the detection of relative positions of the drinking recipient (1), of the individual portion (7) and of the beverage preparation device (3) is provided in each case by means of actuation of respective contact sensors, preferentially by respective pairs of contact sensors (21, 22; 31, 32; 41, 42) associated with at least two locations of a respective displacement path of the drinking recipient (1) on the beverage discharge disposition (2), of individual portion (7) relative to the entry and exit from the beverage preparation device (3) and of total opening and closing of the beverage preparation device (3), and so that respective actuation data are communicated to said control means (9).
It is further preferred when the detection of the relative position of the access disposition (5), including the total opening and total closure, is provided in each case by means of actuation of contact sensors associated with at least one of: access disposition (5) and a respective actuation device.
As known in general in this type of systems, after turning the apparatus (10) on there is a first phase for providing operation conditions, including readiness of the heating temperature, after which each operation cycle basically includes the introduction of individual portion (7) in the beverage preparation device (3), the placement of the drinking recipient (1) in position of collecting the beverage, the start of the fluid injection, and the end of the beverage discharge, with ejection of the individual portion (7) and removal of the drinking recipient (1).
In a first phase, the apparatus (10) is turned on, after which there is an automatic confirmation of the position of the actuation device (4) corresponding to an open beverage preparation device (3), and the actuation of the heating means is initiated so as to reach an operating temperature. At the end of this phase the apparatus (10) can display information of operational readiness to the user.
In a second phase, the individual portion (7) is supplied to the beverage preparation device (3) and the drinking recipient (1) is placed on the beverage discharge disposition (2), whereby the sequence of these steps can be random.
In the case of this embodiment, a first portion sensor (31) is provided on a region upstream of the beverage preparation device (3), in respect of the supply path of the individual portion (7), and a second portion sensor (32) on a region downstream thereof. It is preferred when said portion sensors (31, 32) are arranged in the proximity of the beverage preparation device (3), so that can be further actuated in case of an eventual jamming of the individual portion (7) in those regions.
The individual portion (7) is supplied so that its passage can be detected at the entry into the beverage preparation device (3), preferentially by an entry sensor (31), then the actuation of the actuation device (4) is automatically triggered for closing the beverage preparation device (3). Said closed position is inferred based upon the detection of actuation of a first position sensor (41) associated with a first edge of path of said actuation device (4).
The user places the drinking recipient (1) so that its correct placement can be confirmed, for example by means of actuation of a first recipient sensor (21) of mechanical switch type—vide
In particular, this operation cycle therefore includes the assessment by the control means (9) of detection of actuation of the entry sensor (31), of detection of position of the actuation device (4) and finally, of detection of drinking recipient (1) in a correct retention position on the beverage discharge disposition (2).
The beginning of the fluid circulation phase can only take place after confirmation of these conditions, in particular after a given period of time, for example 1 to 5 seconds, after detection of the retention of the drinking recipient (1) on the beverage discharge disposition (2).
The actuation by the user of a specific interface for this purpose on said apparatus (10) is herewith advantageously not required. At the end of the beverage discharge, the actuation device (4) is actuated for opening, thereby providing the ejection of the individual portion (7) out of the beverage preparation device (3).
Moreover, in this case, it is the opening of the access disposition (5) of the apparatus (10), and not the actuation of another specific interface on the apparatus (10), that triggers the start of the initial phase including switching on the control means (9), and providing operating readiness of the flow heating means and pressurization means. It is further confirmed that the beverage preparation device (3) is closed. This can be advantageous for example in the case that the operation cycle is of washing of the hydraulic circuit, and not of beverage preparation.
The second phase is triggered thereafter by the placement of the drinking recipient (1). There is first a confirmation of the correct retention thereof on a first position, by means of contact with a recipient sensor (21) associated with the beverage discharge disposition (2)—vide
With this confirmation, the opening of the beverage preparation device (3) is triggered and information can be displayed to the user that he can now insert the individual portion (7).
The entry of the individual portion (7) is likewise detected after supply thereof and the closing of the beverage preparation device (3) is triggered, whereby there is afterwards confirmed whether the actuation device (4) reaches its final position.
If that is not the case, information of jammed individual portion (7) can be displayed to the user.
In case of confirmation of closing, the user can then additionally rotate the drinking recipient (1) to a second position along a handling alignment (A), corresponding to the quantity of beverage that he wishes—vide
As represented, the control means (9) apprehend data associated with a plurality of control events, including the entry of individual portion (7) in the beverage preparation device (3), the position of complete closing of the latter, and the position of retention of the drinking recipient (1) on the beverage discharge disposition (2). After confirmation of these control events, the readiness for beginning of fluid injection and beverage discharge is displayed to the user.
Moreover, the detection of placement of the drinking recipient (1) on the beverage discharge disposition (2) automatically triggers the opening of the beverage preparation device (3) to enable the introduction of individual portion (7).
It thus advantageously results that there is minimized the number of interaction required by the user. In particular, the user only has to place the drinking recipient (1) and introduce the individual portion (7) on the apparatus (10), not being required to actuate levers or press buttons to prepare a beverage. The apparatus (10) can also be devoid of interfaces specific for this purpose.
In particular, after conclusion of the beverage discharge, the beverage preparation device (3) can be driven to an open position, so that the individual portion (7) can be ejected out of it.
Said driving to an open position can be automatically triggered after conclusion of the beverage discharge.
It is preferred when the actuation of opening of the beverage preparation device (3) can only be carried out after detection of a manipulation of the drinking recipient (1) on said beverage discharge disposition (2).
The detection of the manipulation can be carried out by said second recipient sensor (22), for example detecting its manipulation in a second direction along said handling alignment (A)—vide
It is preferred when the actuation of opening of the beverage preparation device (3) is triggered by the cessation of actuation of said first recipient sensor (21), corresponding to the removal from the retention position. An eventual discharge of rests of beverage still accumulated under pressure inside the beverage preparation device (3) while closed, can be thus prevented.
The control means (9) can be actuated so that the start of fluid supply (FS) can be triggered after manipulation of the drinking recipient (1) on said beverage discharge disposition (2), even in case that there has not been previously detected the presence or the entry of an individual portion (7) in the beverage preparation device (3).
In fact, this can be the case of flow circulation for the purpose of cleaning the fluid circulation means.
Alternatively, as represented in
The removal of said first lid (51) can be detected by retention elements (53) thereof provided as switches, and can actuate the start of a pre-heating phase and operative readiness of the apparatus (10).
The placement of the drinking recipient (1) in a first operative position on the beverage discharge disposition (2) can actuate the opening of a second lid (52) associated with the entry of the individual portion (7), and to the beverage preparation device (3). This second lid (52) and the beverage preparation device (3) can be automatically closed after the supply of individual portion (7) is detected, or after a previously defined period of time without it happening.
Said first operative position can be detected, so that can trigger for example the opening of the beverage preparation device (3).
Said apparatus (10) can further comprises progress display means (11) including a plurality of visible elements arranged next to each other, preferentially of similar shape and dimension, adapted so that can communicate to the user, preferentially collectively, at least one of:
It is preferred when said progress display means (11) are provided in adjacent manner along at least one common alignment, preferentially an alignment of linear or curved type, preferentially in the proximity of said beverage discharge disposition (2).
Moreover, said apparatus (10) can further comprise readiness display means (12) adapted so that can individually or collectively display to the user at least one of:
