[0045] As an example, the additive substances to be mixed with water can be syrups, flavorings, mineral substances (magnesium, calcium, potassium, etc.), dissolved minerals, vitamins, coffee extracts (caffeine or more), the extracts, fruit juice, etc. The additive substances can be contained in specific containers, such as bag-in-box containers. These containers can be inserted in the additive substances feeding apparatus 24 and can be removed when empty.

[0046] The beverage preparation apparatus 18 comprises at least one mixing and dispensing nozzle 28 and at least one alcove 64, which is obtained on the door 16 and which defines a seat 66, open on the outer surface of the same door 16, to hold at least one container into which the beverage dispensed through the nozzle 28 flows. Thus, each user of the machine 10 can put in the seat 66 of the alcove 64 a container (glass, cup, bottle, canteen, etc.) to receive the desired beverage. The selection of the kind of beverage to be dispensed can be done by a control panel of the machine 10, which is usually disposed on the outer surface of the door 16, near the alcove 64. On the same outer surface of the door 16 a payment device of the beverages can be provided.

[0047] The water supply apparatus 20 is provided with one or more solenoid valves 50, 52, 54 (FIG. 1) each coupled to a respective water delivery pipe 22 to the beverage preparation apparatus 18. According to the invention, the solenoid valves 50, 52, 54 are positioned within the housing chamber at the door compartment of the main casing 12 to be immediately and easily accessible when the door 16 is open during respective adjustment and/or maintenance operations. According to the embodiment herewith described, the solenoid valves 50, 52, 54 are immediately accessible when the door 16 is open, because they are position in front of at least one or of all the other apparatuses arranged inside the main casing 12 of the machine 10, but different configurations can be used.

[0048] As known, the water supply apparatus 20 is provided with at least one water chilling unit 56, as well as of at least a water carbonator-soda maker. These devices are illustrated in the hydraulic diagram of FIG. 4. According to the embodiment herewith described, the solenoid valves 50, 52, 54 are positioned in front of the water chilling unit 56, such as to be more easily accessible, but different configurations can be used.

[0049] As shown, the solenoid valves 50, 52, 54 can be mounted on a single support frame 58 (FIG. 1) which is arranged within the housing chamber at the door compartment of the main casing 12 so as to be opposite to the door 16 when the same door 16 is closed. The solenoid valves 50, 52, 54 can also be at least partially covered by a respective protection carter 60 (FIG. 2). The solenoid valves 50, 52, 54 can further be mounted at a different height from the others with respect to a support surface of the machine 10, so as to allow a more functional connection of the hydraulic tubes to said solenoid valves 50, 52, 54. For the same object, the water delivery pipes 22 are provided with respective delivery pipe portions 62 exiting from respective solenoid valves 50, 52, 54, wherein the delivery pipe portions 62 are oriented towards the hinging axis A of the door 16.

[0050] According to further embodiments, not illustrated, two or more support frames can be used to mount the solenoid valves on, or different kinds of mountings can be used.

[0051] As illustrate in the hydraulic diagram of FIG. 4 and in the detailed view of FIG. 5, all the water delivery pipes 22 and all the additive substances delivering pipes 26 are hydraulically connected to the nozzle 28, which is designed for mixing water with the additive substances, so as to obtain the beverage, and for delivering the beverage. In particular, the water supply apparatus 20 and the additive substances feeding apparatus 24 are arranged in the housing chamber, so are hydraulically connected to the nozzle 28 by the aforementioned water delivery pipes 22 and additive substances delivering pipes 26. In the embodiment illustrated in the figures, the beverage preparation apparatus 18 comprises a single mixing and dispensing nozzle 28, but two or more nozzles can be provided according to the needs.

[0052] Conveniently, the nozzle 28 is fixed to the alcove 64 to ensure easy access to the machine 10 apparatuses and devices arranged within the housing chamber when the door 16 is open. Therefore, it is not necessary to provide a specific split in the alcove 64 to allow the passage of one or more nozzles, as in the known machines for preparing and delivering beverages where the nozzles are usually fixed to the main casing of the machine itself.

[0053] As illustrated in FIGS. 5 and 6, the water delivery pipes 22 and the additive substances delivering pipes 26 are provided with respective pipe end portions 30 for connection to each the nozzle 28. The pipe end portions 30 can be grouped together so as to form at least one single end tube bundle placed at the nozzle 28 (as illustrated). The grouping of the pipe end portions 30 in a single position, specifically near the nozzle 28, further improves the accessibility to the apparatuses of the machine 10 when the door 16 is open.

[0054] As shown in the embodiment of the machine 10 in the figures, at least one part of the pipe end portions 30 is provided with one or more flow control devices 32 able to identify the passage of fluid in the pipe end portions 30, which are electrically connected to an electronic control unit 34 of the machine 10. Such flow control devices 32 can also be provided if the pipe end portions 30 are not grouped as above described. When said pipe end portions 30 are grouped, these flow control devices 32 can be electrically connected to an electronic control unit 34 of the machine 10 by means of respective electric cables 36 incorporated in the same single tube bundle which groups the pipe end portions 30. As an example, the pipe end portions 30 can be made by flow meters able to determine the presence and/or the passage of fluid in the respective pipe end portions 30 arranged closely to the nozzle 28.

[0055] According to an embodiment, as illustrated in FIG. 5, said flow control devices 32 are coupled to the alcove 34, so as to further improve accessibility to the apparatuses of the machine 10 when the door 16 is open.

[0056] With reference to the same FIGS. 5 and 6, the water delivery pipes 22 and the additive substances delivering pipes 26 are provided with respective pipe intermediate portions 38. The pipe intermediate portions 38 are grouped and joined together in an area of the main casing 12, in particular of the housing chamber, close to the hinging axis A of the door 16. Therefore, even these pipe intermediate portions 38 can form respective intermediate tube bundles that occupy the least possible space inside the main casing 12, or the housing chamber, improving accessibility to the apparatuses of the machine 10.

[0057] As illustrated in FIG. 5, when the door 16 is open, both the intermediate tube bundle of the water delivery pipes 22 and the intermediate tube bundle of the additive substances delivering pipes 26 come out from the upper corner of the main casing 12, or of the housing chamber, placed at the hinging axis A of the door 16, to connect to the nozzle 28. In other words, either the intermediate tube bundle of the water delivery pipes 22 and the intermediate tube bundle of the additive substances delivering pipes 26 are arranged within the main casing 12, within the housing chamber, in a position which is as far away as possible from the door compartment, so as not to hinder access to the apparatuses of the machine 10 in any way.

[0058] At least one protection element 48 to prevent the water delivery pipes 22 and the additive substances delivering pipes 26 from being crushed between the door 16 and the main casing 12 is provided in the housing chamber in the area of the main casing 12 close to the hinging axis A of the door 16. As illustrated in FIG. 9, this protection element 48 can be made by a metallic slat which is hinged to the main casing 12 at and parallel to said hinging axis A of the door 16.

[0059] As illustrated in FIGS. 7 and 8, each nozzle 28 comprises at least two separable components. A first component consists of a collector element 40 (FIG. 7), which protrudes from the inner surface of the door 16 and is arranged for connection with the water delivery pipes 22 and with the additive substances delivering pipes 26. The second component consists of a funnel-shaped dispensing element 42, which is placed downstream of the collector element 40 and faces the seat 66 in the alcove 64. In detail, the lower tapered part of the funnel-shaped dispensing element 42 protrudes inside the seat 66 obtained in the alcove 64 to dispense the drinks into the containers that each user of the machine 10 inserts in the alcove 64 itself.

[0060] The collector element 40 of each nozzle 28 can be provided with a plurality of inlet fittings 44 for all the water delivery pipes 22 and for all the additive substances delivering pipes 26. These inlet fittings 44 are conveniently obtained on a single side 46 of the collector element 40

[0061] According to an embodiment, this single side 46 is spaced from the inner surface of the door 16, for example parallel and opposite to the inner surface of the door 16 or inclined with respect to the same, so as to rationalize the hydraulic connection between the water delivery pipes 22 and the additive substance delivery pipes 26 with the respective nozzle 28.

[0062] According to an embodiment, the machine 10 according to the present invention can be provided with suitable pumping devices for the water and/or for the additive substances, for example peristaltic pumps. As illustrated in FIGS. 1, 2 and 5, these pumping devices (not numbered) are arranged within the housing chamber of the main casing 12 at the door compartment of the main casing 12 to be immediately and easily accessible when the door 16 is open during respective adjustment and/or maintenance operations.

[0063] The pumping devices can also be arranged in front of at least one or all the other apparatuses in the main casing 12 of the machine 10, being immediately accessible once the door 16 is opened.

[0064] In particular, these pumping devices can be arranged in the upper portion of the housing chamber, thus allowing an optimal arrangement of the water delivery pipes 22, of the additive substances delivery pipes 26 and of the flow control devices 32, or of portions of the same or of the relative bundles, so as to rationalize the connection with the nozzle 28. Furthermore, the pumping devices can furthermore be mounted at the same height with respect to a support surface of the machine 10, as illustrated and preferred, or each at a different height from the others.

[0065] These pumping devices can therefore be operatively connected with the flow control devices 32, or with the electronic control unit 34 of the machine 10.

[0066] According to further embodiments, not shown, the pumping devices can be positioned according to different methods with respect to what is described above.

[0067] Therefore, the machine for preparation and dispensing of beverages according to the present invention achieves the aforementioned objects.

[0068] The machine for preparation and dispensing of beverages according to the present invention it is in any case susceptible to numerous modifications and variations, all falling within the same innovative concept; for example, combinations of the described embodiments can also be made and furthermore all the details can be replaced by technically equivalent elements. In practice, the materials used, as well as the shapes and dimensions, may be any according to the technical requirements.
