Description

BEVERAGE VENDING MACHINE

TECHNICAL FIELD

The present invention relates to a beverage vending machine .

The present invention may be used to particular advantage in hot or cold so-called "instant" beverage vending machines, to which the following description refers purely by way of example .

BACKGROUND ART

As is known, instant beverage vending machines normally comprise a cabinet or similar casing defining a compartment, which is closed at the front by a door and houses a number of assemblies for producing and feeding the beverages to a pour or pickup compartment, and one of which may be an assembly for supplying hot water to the pickup compartment .

With the exception of the hot-water supply assembly, each of the above assemblies normally comprises one or more containers for respective soluble materials; and a mixer, normally defined by a hollow body with a mixing chamber inside, which has a top inlet for soluble materials, and one or more inlets, close to the top inlet, for water drawn from a tank - normally a boiler - housed inside the cabinet at a lower level than the mixer, and pressure- fed to the mixing chamber along a supply circuit by a respective pump. At the bottom, the mixing chamber communicates with a beverage outflow conduit via a blending chamber housing a blender.

In actual use, a metered quantity of soluble material and a metered quantity of pressurized Water are fed to the mixer for mixing and blending into the desired beverage, which is fed from the outflow conduit into a cup or other vessel inside the pickup compartment .

The hot-water supply assembly normally comprises a boiler normally shared with the other assemblies, and which comprises a supply pump, the delivery of which is connected by a supply circuit to the pickup compartment. This is normally at least in part located at a higher level than the boiler, and normally communicates with a chamber housing one or more nozzles for feeding soluble powdered material directly into the cup or similar vessel fed beforehand into the pickup compartment .

Instant beverage vending machines of the above type pose various problems in the event of malfunctioning of certain component parts .

As regards the beverage-making assemblies, partial or total clogging of the outflow conduit may result in the mixing chamber gradually filling up to the point of covering the water inlet/s, and even to the point of the beverage overflowing out through the top inlet. In any case, simply covering the water inlets is sufficient, when the supply pump is turned off, for part of the beverage inside the mixing chamber to flow back into the tank or boiler, thus contaminating the water in the tank.

As regards the hot-water supply assembly, turn-off of the supply pump may fail to cut toff the water supply, which continues to be siphoned uncontrollably until the level inside the boiler equals the level of the pickup compartment. This drawback is particularly serious when the boiler constitutes a common tank shared by all the assemblies . Such an occurrence is normally prevented by interrupting the outflow conduit with a mixer, which serves solely as an anti-siphon-effect device. Such a solution, however, is undoubtedly expensive and bulky.

DISCLOSURE OF INVENTION

It is an object of the present invention to provide a beverage vending machine that is cheap and easy to produce and at the same time designed to eliminate the aforementioned drawbacks. According to the present invention, there is provided a beverage vending machine as claimed in Claim 1 and, preferably, in any one of the Claims depending directly or indirectly on Claim 1.

Figure 6 shows a section along line VI-VI in Figure 5;

Figure 7 shows a section along line VII-VII in Figure 5.

BEST MODE FOR CARRYING OUT THE INVENTION

Number 1 in Figure 1 indicates as a whole an instant-beverage vending machine comprising a cabinet 2 closed at the front by a door 3, in which is formed a pickup compartment 4 accessible from the outside and into which a cup (not shown) or similar vessel is fed by known feed devices not shown.

Cabinet 2 houses a frame 5 integral with cabinet 2 and comprising a horizontal plate 6, from a rear edge of which a vertical plate 7 projects upwards, and from an intermediate portion of which a vertical plate 8 projects downwards. Frame 5 supports a known beverage- making unit A comprising a number of assemblies B for making respective beverages, and a hot-water supply assembly C.

Unit' A is improved, in accordance with the present invention, to form a unit 9 similar to unit A and housed in the same position as unit A inside cabinet 2, but comprising a number of improved assemblies B - one of which is shown and indicated by 10 in Figures 2 and 3 - for making respective beverages, and an improved hot- water supply assembly C shown and indicated by 11 in Figure 4.

As regards assemblies 10 and 11, unit 9 may obviously differ from the unit A shown and only comprise one or more assemblies 10, with no assembly 11, or only assembly 11, or assembly 11 and one or more assemblies 10.

As shown in Figure 2, like known assembly B in Figure 1, assembly 10 comprises at least one soluble powdered material container 12 resting on horizontal plate 6 and having, at the front, a downward- facing outflow conduit 13 connected to a known feed device (not shown) housed inside container 12 and powered by a motor

14 fitted to vertical plate 7.

Like assembly B in Figure 1, and as shown more clearly in Figure 3, assembly 10 also comprises a mixer

15 fitted to vertical plate 8, beneath outflow conduit 13 of container 12, and comprising a funnel-shaped hollow body 16, which is fed with both soluble material from container 12 through a top inlet 17, and with pressurized water through at least one tangential inlet 18 (two superimposed inlets 18 in the example shown) located just below inlet 17. Hollow body 16 communicates laterally with a fume suction device 19, and at the bottom - via a blending chamber 20 housing a known blender (not shown) powered by a motor 21 fitted to vertical plate 8 - with an outflow conduit 22 connecting mixer 15 to pickup compartment 4. Like assembly B in Figure 1, and as shown in Figure 2, assembly 10 also comprises a tank 23 normally shared with any other assemblies 10 and normally defined by a boiler; and an immersion pump 24 with a delivery conduit 25. In the Figure 1 assembly B, delivery conduit 25 is connected directly, in a manner not shown, to tangential inlet 18 of hollow body 16; whereas, in the Figure 2 assembly 10, delivery conduit 25 defines the upflow portion of a substantially inverted-U-shaped hydraulic circuit 26, which also comprises a downflow portion indicated as a whole by 27 and comprising mixer 15, conduit 22, and a coupling 28 for connection to tangential inlet 18 (in the example shown, coupling 28 is Y-shaped for parallel connection to the two tangential inlets 18) .

As shown more clearly in Figure 2 and particularly in Figures 5 to 7 , hydraulic circuit 26 also comprises a top portion 29 defined by a substantially horizontal tubular body 30 of a fitting 31, which comprises a tubular inlet member 32 and a tubular outlet member 33, both projecting radially downwards from tubular body 30. Tubular inlet member 32 is connected to the outlet end of delivery conduit 25, and tubular outlet member 33 is connected to the inlet end of coupling 28.

Tubular body 30 is closed at one end by a transverse wall 34, and at the other end by a plug 35, through which a duckbill, one-way valve 36 is fitted axially to connect tubular body 30 to the outside, and is positioned with its bill 37 facing inwards of tubular body 30.

In actual use, if outflow conduit 22 becomes clogged and the liquid level in hollow body 16 rises to cover top tangential inlet 18, stoppage of pump 24 and subsequent backflow of the water in delivery conduit 25 into tank 23 results in no backflow of the liquid in hollow body 16 into tank 23, because the low pressure generated inside fitting 31 by the water in delivery conduit 25 flowing back into tank 23 is immediately compensated by air drawn into tubular body 30 through one-way valve 36, which thus prevents contaminating liquid from reaching tank 23.

As shown in Figure 4, like the known assembly C in Figure 1, assembly 11 comprises a boiler 38 normally shared by all of assemblies 10 and corresponding to tank 23 described above; and an immersion pump 39 with a delivery conduit 40. In the Figure 1 assembly C, delivery conduit 40 is connected directly, in a manner not shown, to an inlet of a mixer M similar to mixer 15 and having an outflow conduit H connected to pickup compartment 4; whereas, in the Figure 4 assembly 11, delivery conduit 40 defines the upflow portion of a substantially inverted-U-shaped hydraulic circuit 41, which also comprises a downflow portion 42 defined by a continuous tube terminating in pickup compartment 4. Hydraulic circuit 41 also comprises a top portion 43 defined by a fitting substantially identical in both structure and location to fitting 31, and indicated by the same reference numbers as fitting 31 in Figures 5 to 7. In actual use, stoppage of pump 39 and subsequent emptying of downflow portion 42 of hydraulic circuit 41 are prevented from siphoning out even part of the water in boiler 38, on account of the low pressure generated inside fitting 31 by emptying downflow portion 42 being compensated immediately by air drawn into tubular body 30 through one-way valve 36.
