(11) Arrow D in FIG. 4 illustrates the movement of dispensing head 20 into the deployed position. Arrow E in FIG. 5 illustrates the movement of dispensing head 20 into the retracted position.

(12) Machine 1 includes a control unit 16 for controlling preparation unit 11,12,13,14,15 to supply beverage 2 to outlet 21. For instance, control unit 16 is connected to a user-interface 17,17, such as a user-interface 17,17 located on dispensing head 20 and movable therewith, e.g. a user-interface 17 that remains accessible to a user when head 20 is in its retracted position and/or a user-interface 17 that is accessible to a user in the deployed position and inaccessible (or hidden) to a user in the retracted position. See FIGS. 1 and 4.

(13) Outlet 21 can be confined in main body 10 when beverage dispensing head 20 is in its retracted position. See FIGS. 1, 2, 3, 5 and 6.

(14) Control unit 16 is configured to: maintain or leave beverage dispensing head 20 in its retracted position when beverage preparation unit 11,12,13,14,15 is not operated to process a liquid such as beverage 2; and/or move beverage dispensing head 20 into its deployed position or maintain or leave it in this position only when control unit 16 operates preparation unit 11,12,13,14,15 to process a liquid for dispensing via outlet 21.

(15) Control unit 16 is typically configured to operate preparation unit 11,12,13,14,15 to prepare beverage 2 when beverage dispensing head 20 is in its deployed position.

(16) Control unit 16 may be configured to operate preparation unit 11,12,13,14,15 to service unit 11,12,13,14,15 when beverage dispensing head 20 is in its deployed position, for instance to carry out a descaling program, such as a descaling with a volume of descaling water corresponding to a plurality of beverage portions delivered via outlet 21 to a service recipient at said placement location 30.

(17) Control unit 16 may be configured to operate preparation unit 11,12,13,14,15 to evacuate residual beverage when beverage dispensing head 20 is in its deployed position or when it is in its retracted position or when it is moved to the deployed position or when it is moved to the retracted position. For instance, preparation unit 11,12,13,14,15 is operated for rinsing outlet 21, such as a rinsing with a volume of rinsing water corresponding to a single beverage portion or less delivered via preparation unit 11,12,13,14,15 to a waste collector 19, e.g. a waste collector 19 located in main body 10 and optionally removable therefrom.

(18) Beverage dispensing head 20 may be moved into its retracted position in at least one of the following instances: immediately at the end of servicing beverage preparation unit 11,12,13,14,15; immediately at the end of preparing a portion of beverage by beverage preparation unit 11,12,13,14,15 or after a short period of time after the end, such as a period of time in the range of 1 to 15 sec, such as to 12 sec, e.g. 5 to 10 sec, optionally beverage dispensing head 20 being maintained in its deployed position upon preparing a portion of beverage to allow during this short period of time a user to request the preparation of a further portion of beverage by preparation unit 11,12,13,14,15; and in the absence of a detection by a sensor 18 connected to control unit 16 of a user-recipient 3 in placement location 30, optionally sensor 18 being an optical or a proximity sensor (FIG. 4).

(19) Beverage dispensing head 20 can be moved into its deployed position: on a user-request of a beverage preparation or of a servicing of the preparation unit 11,12,13,14,15; and/or on a detection by a sensor 18 connected to control unit 16 of a user-recipient 3 in placement location 30, optionally sensor 18 being an optical or a proximity sensor.

(20) Beverage preparation unit 11,12,13,14,15 can have an ingredient mixing module 11 which comprises a first part 11 and a second part 11 that are relatively movable, e.g. by a motor, between a mixing position for mixing ingredients and a transfer position for inserting an ingredient 4 and/or removing waste from the mixing module 11. For instance, module 11 is in fluid connection with source 12 of liquid such as water, such as a source 12 of liquid connected to module 11 via one or more of: a liquid sensor 13 such as a flowmeter, a pump 14 for driving a liquid from source 12 to module 11 and then outlet 21, and a thermal fluid conditioner 15 such as a heater and/or a cooler. See FIG. 1.

(21) Arrow C in FIG. 3 illustrates the relative movement of first and second parts 11,11 into the mixing position. Arrow F in FIG. 6 illustrate the relative movement of first and second parts 11,11 into the transfer position.

(22) Beverage dispensing head 20 can be mechanically connected or linked, e.g. via a cam arrangement and/or gear arrangement such as a spur and/or friction gear arrangement, to one 11 of first and second parts 11,11 that is movable in main body 10 so that dispensing head 20 is moved into: its deployed position when first and second parts 11,11 are relatively moved into the mixing position; and its retracted position when first and second parts 11,11 are relatively moved into the transfer position.

(23) For instance, said one 11 of first and second parts 11,11 forms an upstream part or a downstream part 11 of mixing module 11.

(24) Beverage dispensing head 20 and said one 11 of first and second parts 11,11 can be mechanically disconnectable, e.g. via a connection actuator controlled by the control unit 16 such as a magnetic actuator, so as to allow a relative movement of first and second parts 11,11 without moving dispensing head 20.

(25) For instance, beverage dispensing head 20 in the deployed position and said one 11 of first and second parts 11,11 in the mixing position can be mechanically disconnected to relatively move first and second parts 11,11 back and forth between the mixing position and transfer position when a user requests the preparation of a further portion of beverage 2 by preparation unit 11,12,13,14,15: before the end of preparing a portion of beverage 2 by preparation unit 11,12,13,14,15; or within a short period of time after the end of preparing a portion of beverage 2 by preparation unit 11,12,13,14,15, such as a period of time in the range of 1 to 15 sec, such as 3 to 12 sec, e.g. 5 to 10 sec.

(26) Control unit 16 can be configured to disconnect dispensing head 20 in its retracted position from said one 11 of first and second parts 11,11 to relatively move first and second parts 11,11 into the mixing position, e.g. to unclog mixing module 11 or to rinse mixing module 11 such as a rinsing with a volume of rinsing water corresponding to a single beverage preparation or less delivered via preparation unit 11,12,13,14,15 to a waste collector 19, and then to relatively move first and second parts 11,11 back into the transfer position, e.g. a waste collector 19 located in main body 10 and optionally removable therefrom.

(27) Main body 10 can have a transfer channel 40 for supplying an ingredient 4 to mixing module 11. Channel may extend to a waste collector 19, e.g. a waste collector 19 located in main body 10 and optionally removable therefrom.

(28) Machine 1 can include a capsule loader 41 associated with transfer channel 40 for loading a capsule 4.

(29) Capsule 4 can have a body, e.g. a generally straight or tapered body and optionally a circular peripheral annulus flange, e.g. a flexible or rigid flange, extending from a peripheral part, e.g. an edge or face, of the body.

(30) Capsule 4 may contain a flavoring ingredient for preparing tea, coffee, hot chocolate, cold chocolate, milk, soup or baby food.

(31) Capsule loader 41 can have: a capsule holding configuration for holding a capsule 4 away from mixing module 11; and a capsule releasing configuration for releasing the capsule in or into transfer channel 40 towards the mixing module 11.

(32) Loader 41 may have a capsule gate 41 that is movable, such as pivotable and/or translatable, between a position obstructing transfer channel 40 for preventing a passage of capsule 4 along channel 40 and a position clearing transfer channel 40 for allowing a passage of capsule 4 along the channel 40.

(33) Arrow A in FIG. 2 indicates the passage from the holding configuration to the releasing configuration. Arrow B in FIG. 3 indicates the passage from the holding configuration to the releasing configuration.

(34) Immediately after releasing capsule 4 to mixing module 11, loader 41 may be passed from the releasing configuration to the holding configuration so that transfer channel 40 is opened only when needed to release a capsule 4.

(35) Loader 41 can have a shape complementary to a shape of capsule 4.

(36) Loader 41 may have an actuator for passing from the holding configuration to the releasing configuration and vice versa, such as an actuator controlled by control unit 16.

(37) Loader 41 can have a capsule sensor for sensing a presence of a capsule 4 on capsule loader 41 and optionally sensing a type of the capsule. For instance, capsule loader 41 is controlled by control unit 16 to automatically release a sensed capsule 4 when mixing module 11 is in the transfer position.

(38) Machine 1 may include a directing fluid guide 22 upstream outlet 21 and downstream preparation unit 11,12,13,14,15, directing guide 22 being configured to direct residual liquid from preparation unit 11,12,13,14,15 to a waste collector 19 when preparation unit 11,12,13,14,15 is not operated to process a beverage 2, e.g. a waste collector 19 located in the main body 10 and optionally removable therefrom. Outlet 21 and preparation unit 11,12,13,14,15 may be configured so that directing guide 22 directs liquid from preparation unit 11,12,13,14,15: in a dispensing configuration to outlet 21 when dispensing head 20 is in its deployed position; and in a collecting configuration to the waste collector when dispensing head 20 is in its retracted position.

(39) Directing fluid guide 22 can have a guide inlet in fluid connection with preparation unit 11,12,13,14,15 so that the guide inlet is: directly connected to the preparation unit, the directing fluid guide having a guide outlet or draining edge that is in fluidic communication selectively with the dispensing head outlet or with the waste collector; or separate from the preparation unit 11,12,13,14,15, the directing fluid guide having: a collecting surface 22a, e.g. a channel of funnel, for collecting liquid 2 flowing from an outlet 11a of preparation unit 11,12,13,14,15, e.g. of a mixing module 11 of preparation unit 11,12,13,14,15; and at least one guide outlet or draining edge 22,22 for directing liquid collected by collecting surface 22a to dispensing head outlet 21 and/or to waste collector 19, such as: a single guide outlet or draining edge for directing such liquid selectively to head outlet or to the waste collector; or a first guide outlet or draining edge 22 for draining such liquid to head outlet 21 and a second guide outlet or draining edge 22 for directing such liquid to waste collector 19.

(40) Directing fluid guide 22 can be actuated between the dispensing configuration and the collecting configuration by an actuator controlled by control unit 16.

(41) Directing fluid guide 22 may be entirely confined in main body 10 and/or dispensing head 20.

(42) Directing guide 22 and dispensing head 20 can be mechanically connected, e.g. by a cam arrangement and/or a gear arrangement such as a spur and/or friction gear arrangement, so that the movement of the dispensing head 20: from its retracted position into its deployed position is linked to or causes or is caused by a relative movement of directing device 22 into the dispensing configuration to direct fluid to outlet 21; and/or from its deployed position into its retracted position is linked to or causes or is caused by a relative movement of directing device 22 into the collecting configuration to direct fluid to waste collector 19.

(43) Dispensing head 20 can be configured to translate along a straight direction 11 (FIG. 2) from the retracted position into the deployed position and vice versa. For instance, beverage preparation unit 11,12,13,14,15 has a or the above ingredient mixing module 11 which comprises first part 11 and second part 11 that are relatively movable generally along straight direction 11 between a mixing position for mixing ingredients and a transfer position for inserting an ingredient 4 and/or removing waste from mixing module 11.

(44) Dispensing head 20 may be configured to move inwards into an outside housing or frame 10 of main body 10 into retracted position and outwards of outside housing or frame 10 into a deployed position. For instance, dispensing head 20 in the retracted position has an outside face 25, e.g. a front face 25, that is flush, e.g. entirely flush, with outside housing or frame 10.
