Description

INFUSION UNIT FOR MAKING AN AROMATIC DRINK
DESCRIPTION
The present invention relates to an infusion unit for producing an aromatic beverage.
The infusion unit, which without distinction may have automatic, semi-automatic or manual movement, is of the type comprising an infusion cylinder having a seating chamber for a package, in particular a paper capsule, containing a charge of aromatic essence and a chamber closing piston which is mobile between a package charging position and a dispensing position, wherein it engages with the piston with the longitudinal axis substantially oriented horizontally.
The aromatic essence may be of any kind, for example coffee powder, barley, tea, etc.
In a traditional infusion unit for coffee machine of the type described above, one of the main problems to solve is that, inserting the capsule in the relevant chamber and moving the chamber to the dispensing position, the capsule may come out of the chamber before it is positioned against the piston for dispensing. Another problem is that in order to obtain a good extraction of coffee liquid while dispensing, the capsule must be constantly compressed between the chamber and closing piston. Otherwise, since the paper capsule has no stiff containment for the coffee powder, the extracted liquid would be little dense and with a poor amount and quality of the cream.
The technical task of the present invention therefore is to provide an infusion unit for making an aromatic drink which allows eliminating the above technical drawbacks of the prior art.
Within the scope of this technical task, an object of the invention is to provide an infusion unit for making an aromatic drink which allows the package of aromatic essence charge to keep the correct position into the chamber in a simple, effective, safe and precise manner during the handling thereof towards the dispensing position.
Another object of the invention is to provide an infusion unit for making an aromatic drink which allows making the aromatic drink with the desired fullness, amount and quality of cream. Last but not least, another object of the invention is to provide a method for handling a package of an aromatic essence charge in an infusion unit for making an aromatic drink having optimal organoleptic properties.
The technical task, as well as these and other objects, according to the present invention are achieved by providing an infusion unit according to claim I.
The infusion unit of the invention allows having the package of aromatic essence charge in the correct position when the chamber reaches the dispensing position, so as to have the ideal conditions to obtain a very effective infusion.
Further features of the present invention are further defined in the following claims.

Equivalent parts in the different preferred embodiments of the invention will be indicated with the same reference numerals.
With reference to figures 1-7, there is shown an infusion unit for making an aromatic drink, globally indicated with reference numeral 1.
The infusion unit 1 comprises an infusion cylinder 2 having a chamber 3 for receiving a package 4 of an aromatic essence charge, and a piston 5 for closing chamber 3.
Package 4 in particular is a paper capsule containing powder of the aromatic essence, for example coffee.
Chamber 3 is mobile, by the effect of a rotary- translation, between a charging position of package 4, wherein it has a longitudinal axis 6 oriented upwards, and a dispensing position wherein it engages with piston 5 with the longitudinal axis 6 substantially oriented horizontally.
In this specific case, a handle 35 is provided for actuating cylinder 2 from the charging position to the dispensing position and vice versa. As an alternative, cylinder 2 may also be motor-driven.
Handle 35 is hinged at 36 at the opposite shoulders 57 of the frame of the infusion unit 1 that contain cylinder 2 and piston 5.
Handle 35 is hinged in 37 with an end of a connecting rod 38 the other end whereof is in turn hinged to a pin 39 supporting cylinder 2 in rotation.
Pin 39 is positioned eccentric-wise relative to cylinder 2 and it slides in a guiding slot 40 obtained on shoulders 57 with development parallel to the coupling axis substantially horizontal between chamber 3 and piston 5.
The axes of hinges 36, 37 and 39 are parallel to each other and are orthogonal to the substantially horizontal coupling axis between chamber 3 and piston 5.
The translation of cylinder 2 along the substantially coupling axis between chamber 3 and piston 5 is ensured by a translation guide 51 protruding from the opposite shoulders 57 of the frame of the infusion unit 1.
Advantageously, the infusion unit 1 has means 7 for a releasable retaining of the external edge 8 of package 4 against the front delimiting surface
9 of chamber 3 in a temporary position of package 4 spaced from the bottom of chamber 3, and means
10 for actuating the retaining means 7, suitable for actuating the retaining means 7 in the stroke of chamber 3 towards the dispensing position for retaining package 4 in its temporary position.
The retaining means 7 comprise a stop 11 preferably plate-shaped that extends above the front delimiting surface 9 of chamber 3 and is slidingly supported by cylinder 2 relative whereto it is mobile by the effect of the actuating means 10 between a position spaced from the front delimiting surface 9 of chamber 3 and a position juxtaposed to the front delimiting surface 9 of chamber 3 whereat the external edge 8 of package 4 remains stuck between stop 11 and the front delimiting surface 9 of chamber 3. Stop 11 has a profile matching that of the external edge of package 4 for having an extended overlapping portion therewith and as a consequence, for exerting a firm retaining.
In the case shown by way of an example wherein package 4 is a circular capsule, stop 11 has an arched profile 30 having the same bending as the peripheral capsule edge.
The front delimiting surface 9 of chamber 3 has a lowering 31 where stop 11 is seated in the position juxtaposed to the front delimiting surface 9 of chamber 3.
Lowering 31 has a depth substantially equal to the thickness of stop 11 so that in the position juxtaposed to the front delimiting surface 9 of chamber 3, the front surface of stop 11 is substantially aligned with the non-lowered portion of the front delimiting surface 9 of chamber 3.
Stop 11 is supported by two bars 32 sliding parallel to the axis of chamber 3 along guides 33 obtained in the body of cylinder 2 laterally to chamber 3.
Bars 32 are in turn supported by a slide 50. The actuating means 10 comprise a pin 12 that extends from slide 50,
Pin 12 slides along a cam profile 20 obtained on shoulders 57 of the support frame of the infusion unit 1.
Pin 12 is mobile along the cam profile 20 by the action of and in contrast with an elastic element 13, for example a helical spring, which connects slide 50 with cylinder 2.
The cam profile 20 comprises an inclined plane 59 that separates two horizontal planes 60 and 61.
When pin 12 is on plane 61 stop 11 is in the release position, spaced from the front delimiting surface 9 of chamber 3, whereas when pin 12 is on plane 60 stop 11 is in the gripping position, juxtaposed to the front delimiting surface 9 of chamber 3.
The retaining force exerted by stop 11 depends on the deformation and stiffness of the elastic element 13 and is calibrated so as to allow the extraction of the external edge 8 of package 4 by the effect of the thrust exerted by the closing piston 5 against package 4 when chamber 3 reaches the dispensing position.
The closing piston 5 comprises a fixed portion 14 whereon a mobile portion 15 is mounted, having a valve 16 suitable, upon dispensing, for creating a pressure drop that generates a thrust force on the mobile portion 15 for extracting it from the fixed portion 14 and compressing package 4 moving it from its temporary position to a final position against the bottom of chamber 3.
One or more automatic return springs 17 of the mobile portion 15 towards the retracted position into the fixed portion 14 are provided between the fixed portion 14 and the mobile portion 15.
Valve 16 is a mushroom-shaped on-off valve mobile in contrast with and by the action of a spring 63, inserted along a conduit 64 for feeding water to a closed chamber 65 delimited between the inner fixed portion 14 and the outer mobile portion 15.
A conduit 66 for feeding the infusion water to the front filter 67 of piston 5 is also provided in piston 5, wherefrom the infusion water enters the infusion chamber 3.
An on-off valve 68 mobile in contract with and by the action of a spring 69 is provided in conduit 66, too.
Springs 63 and 69 are calibrated so that the opening of the on-off valve 16 takes place at a pressure below that required for opening the on- off valve 68.
Cylinder 2 underneath the base of chamber 3 has a conduit 70 for conveying the infusion produced in chamber 3 outwards.
Chamber 3 seats a sliding stem 18 for ejecting package 4.
Stem 18 has an enlarged and flattened head 71 that, as shall be seen, acts as support and guide for package 4 during the charging thereof in the temporary position in chamber 3.
Shoulders 57 of the support frame of the infusion unit 1 carry a pin 52 for intercepting the base of stem 18 for the extraction thereof from chamber 3.
The interception pin 52 is freely mobile along a vertical guide 72 for releasing stem 18 during the rotation of cylinder 2.
The support frame of the infusion unit 1 further has a stopping surface 19 suitable for intercepting the ejecting stem 18 during the rotation of cylinder 2 for locking it into a position substantially flush with the front delimiting surface 9 of chamber 3 so that with its head 71 it may act, as said above, as support and guide for package 4 when, with chamber 3 in the charging position, package 4 is charged into the temporary position thereof.
The operation of the infusion unit briefly is as follows .
The infusion unit 1 initially is with handle 35 in open position wherein chamber 3 is inclined upwards for receiving package 4, stop 11 is in the release position and stem 18 is positioned with its head 71 flush with the front delimiting surface 9 of chamber 3.
Package 4 fed towards chamber 3 slides on head 71 of stem 18 and achieves its temporary position. Without this device, package 4, especially if in the form of a paper capsule, may enter chamber 3 bending its paper edge in an abnormal manner, thus impairing the correct execution of the grip by stop 11. During the closing of handle 35 pin 12, sliding on cam 20, moves from plane 61 to plane 60 causing the actuation of stop 11 which, retracting, traps the edge of package 4 against the front delimiting surface 9 of chamber 3. In this way, package 4 moves integrally with chamber 3 until it encounters piston 5.
Cylinder 2 rotates up to aligning its axis with that of piston 5 it couples with.
At the time of contact with piston 5, package 4 is pushed into chamber 3. The edge of package 4 trapped between the front delimiting surface 9 of chamber 3 and stop 11 slips away by the effect of the pulling of package 4 inside chamber 3.
The subsequent compression of package 4 takes place after the start of the pump (not shown) that dispenses the hot infusion water towards the infusion unit 1.
More precisely, when the pump is started, chamber 65 of water under pressure is created between fixed portion 14 and mobile portion 15 of piston 5.
At the time of dispensing, the pressure drop makes the mobile portion 15 move away from the fixed portion 14 and compress package 4 present in chamber 3 against the bottom of chamber 3: the extent of the compression is determined by the extent of the pressure drop created by the on-off valve 16.
With reference to figures 8-13, there is shown an infusion unit for making an aromatic drink, globally indicated with reference numeral 1.
The infusion unit comprises an infusion cylinder 2 having a chamber 3 for receiving a package 4 of an aromatic essence charge, and a piston 5 for closing chamber 3.
Chamber 3 is mobile, by the effect of a translation, between a charging position of package 4, wherein it has a longitudinal axis 6 substantially oriented horizontally, and a dispensing position wherein it engages with piston 5 with the longitudinal axis 6 always substantially oriented horizontally.
Also in this specific case, a handle 35 is provided for actuating cylinder 2 from the charging position to the dispensing position and vice versa .
Handle 35 is hinged at 36 at the opposite shoulders 57 of the frame of the infusion unit 1 that contain cylinder 2 and piston 5.
Handle 35 is hinged in 37 with an end of a connecting rod 38 the other end whereof is in turn hinged to a pin 39 supporting cylinder 2 in rotation.
Pin 39 is positioned eccentric-wise relative to cylinder 2 and it slides in a guiding slot 40 obtained on shoulders 57 with development parallel to the coupling axis substantially horizontal between chamber 3 and piston 5.
The translation of cylinder 2 along the substantially coupling axis between chamber 3 and piston 5 is ensured by a translation guide 51 protruding from the opposite shoulders 57 of the frame of the infusion unit 1.
Advantageously, the infusion unit 1 has means 7 for a releasable retaining of the external edge 8 of package 4 against the front delimiting surface 9 of chamber 3 in a temporary position of package 4 spaced from the bottom of chamber 3, and means 10 for actuating the retaining means 1, suitable for actuating the retaining means 7 in the stroke of chamber 3 towards the dispensing position for retaining package 4 in its temporary position.
The retaining means 7 comprise a stop 11 preferably plate-shaped that extends above the front delimiting surface 9 of chamber 3 and is slidingly supported by cylinder 2 relative whereto it is mobile by the effect of the actuating means 10 between a position spaced from the front delimiting surface 9 of chamber 3 and a position juxtaposed to the front delimiting surface 9 of chamber 3 whereat the external edge 8 of package 4 remains stuck between stop 11 and the front delimiting surface 9 of chamber 3.
Stop 11 has a profile matching that of the external edge of package 4 for having an extended overlapping portion therewith and as a consequence, for exerting a firm retaining.
The front delimiting surface 9 of chamber 3 has a lowering 31 where stop 11 is seated in the position juxtaposed to the front delimiting surface 9 of chamber 3. Stop 11 is supported by two bars 32 sliding parallel to the axis of chamber 3 along guides 33 obtained in the body of cylinder 2 laterally to chamber 3.
The actuating means 10 comprise an abutment 12 against a stop 20.
The closing piston 5 comprises a fixed portion 14 whereon a mobile portion 15 is mounted.
Its structure is similar to that described for the first preferred embodiment of the invention.
Chamber 3 seats a sliding stem 18 for ejecting package 4.
Stem 18 has an enlarged and flattened head 71.
The rear abutment 52 of ejector 18 is integral with a slot that hinges in pin 37. For a wide rotation of lever 3 from horizontal to the vertical position, slot 101 makes the rear abutment 52 stay still and perform its function for ejecting the empty charge. Beyond a certain angle, slot 101 ends and abutment 52 is lifted, thus releasing ejector 18 (as is seen in figure 8) .
During the closing of handle 35 abutment 12, intercepted by the cam stop 20, causes the actuation of stop 11 which, retracting, traps the edge of package 4 against the front delimiting surface 9 of chamber 3. In this way, package 4 moves integrally with chamber 3 until it encounters piston 5.
Cylinder 2 translates horizontally until the edge of package 4 trapped between the front delimiting surface 9 of chamber 3 and stop 11 slips away by the effect of the pulling of package 4 inside chamber 3.
A possible version (not shown) of the invention keeps into account the fact that it was found that for an optimum dispensing, the capsule should be compressed well before the dispensing starts and a space should be left wherein the capsule may expand (it swells as water is absorbed) during the dispensing.
The version consists in inserting an interposition spring between the bottom of chamber 3 and the back of head 71 of stem 18. The capsule, during the movement of piston 5 for closing chamber 3, compresses in contrast to the interposition spring that keeps head 71 of stem 18 slightly lifted from the bottom of chamber 3. At the end of the movement of piston 5, when the dispensing of the infusion water starts, the pressure force generated by the expansion of the capsule is released against head 71 of stem 18, which moves back towards the bottom of chamber 3, the combination of the compression force of the piston and of the pressure force of the capsule being higher than the elastic force of the interposition spring.
A further possible version of the invention relates to the thrust of the mobile portion 15 of piston 5 towards the extended portion, which may be generated also without the need of on-off valves that create the pressure drop, but more simply using the difference between inside and outside area of the mobile portion 15 exposed to the water pressure orthogonally to the moving direction. The outer wet front surface of the mobile portion 15 of piston 5 is less extended than the inner wet surface of the rear side of the mobile portion 15 so that the water pressure generates an extension force on the mobile portion 15 stronger than the retraction force. The infusion unit of the present invention allows optimising the infusion quality since package 4 achieves with accuracy and certainty any subsequent position of the correct design path that brings it from the charging position to the infusion position wherein it can thus be subject to the correct compression force by the closing piston.
The infusion unit thus conceived is susceptible to numerous modifications and variants, all falling within the inventive concept; moreover all details can be replaced by other technically equivalent details .
In the practice, the materials used as well as the sizes, can be whatever, according to the technical requirements and to the prior art.
