Description

The invention relates to the evacuation of agglomerate present in the cavity of a utensil such as an infusion compartment of a machine for preparing beverages. hot. The invention relates to a device designed to evacuate this agglomerate. More particularly, the invention relates to a device for evacuating the infusion agglomerate resulting from the preparation of a hot drink, more particularly to evacuate the agglomerated coffee in a brewing compartment. a coffee machine.

Prior art

Some methods of making beverages include infusing water on a substance that forms a permeable medium. In the case of coffee making, boiling water or steam passes through a dose of ground coffee to extract the aromas. After use, the coffee dose must be removed from the compartment in which it was confined before another coffee can be prepared. However, after contact with water and / or pressure, the dose of coffee agglomerates and adheres to the surfaces of the compartment. Special effort and care are needed to empty and clean the compartment. The difficulty in evacuating the dose of coffee increases in cases where it has been previously compacted before infusion, because the agglomerate formed shows increased cohesion.

The shape of the compartment or the filter holder further complicates the evacuation operation. The latter can form a substantially cylindrical cavity whose depth reduces the extraction efficiency of the coffee. The compartment is often provided with several cylindrical parts of different diameters, which define parts of different depths, and which give place to corners difficult to clean. The prior art proposes solutions for extracting a dose of compressed coffee after infusion.

GB812833 discloses a device for emptying a coffee machine infusion compartment after use of the coffee. Following the completion of a dose of coffee, the infusion compartment is automatically driven under a screw. Always automatically, this screw is introduced into the infusion compartment and removes in a rotational movement the used coffee. The screw is housed in a box that stores the used coffee after extraction.

The device makes it possible to extract coffee but not to evacuate it permanently. The box must also be emptied regularly to avoid jams and to preserve the capacity of the screw to retain extracted coffee. The casing must be emptied as soon as a critical filling level is reached. It is not apparent how such a device can be used with infusion compartments having various shapes.

Document FR2225126 describes an apparatus for preparing an infusion. This device has the ability to empty the infusion compartment and clean a perforated wall adjacent to the compartment in question. The compartment is mounted on an articulated arm. In a reversal movement, the compartment is stopped by a stop which generates a shock of nature to take off the coffee grounds. The perforated wall is movable in translation. In its translational movement, it rubs against a transverse brush. The bristles of the brush can be inserted into the recesses of the perforated wall to extract the smallest bean. The brush can evacuate each remaining ground coffee even when the wall is a grid. The reversal kinematics of the infusion compartment advantageously allows emptying it in one operation without coffee can fall back into it. This solution does not clean the inner walls of the brewing compartment, so that traces of ground coffee can survive. In addition, coffee can be particularly compressed before infusion, which can create an extremely compact and adhesive block. It therefore becomes hard to evacuate. Remnants of coffee can eventually add up, gradually blocking the useful volume of the brewing compartment.

WO 2009/127983 A1 discloses a device comprising a compatible cleaning head for cleaning single-dose and double-dose cavity infusion compartments. The head includes a pallet whose profile corresponds essentially to that of a single-dose cavity. The pallet is, however, provided with two resilient arms intended to correspond to a double-dose cavity.

Patent document WO 2012/107246 A1 discloses a machine for cleaning an infusion compartment of a coffee machine. The machine comprises a cleaning head having a fixed form. The cleaning head is formed of four pallets whose upper profile forms a projection intended to allow adequate penetration of an infusion cavity. When using the machine, the filter is returned to the cleaning head which is rotated by a motor.

The patent document EP 1 803 380 A2 also discloses a machine for cleaning an infusion compartment of a coffee machine. When cleaning, the filter is returned to the cleaning head. The bearing force along the axis which carries the cleaning head is transformed into a rotational movement about this axis. The cleaning head has a specific shape adapted to an infusion compartment.

None of the documents discloses a tank for collecting the evacuated residue remains, easy to empty. SUMMARY OF THE INVENTION The object of the invention is to solve at least one of the problems mentioned in the prior art. The invention aims to provide a simple, effective and economical solution to the evacuation of an agglomerate formed in the cavity of a utensil such as an infusion chamber of a machine for preparing drinks by infusion. More particularly, the object of the invention is to propose an ecological solution for the evacuation of the agglomerate in question, applicable to a plurality of forms of infusion compartments, in particular single dose compartments and double dose compartments, The device according to the present invention makes it possible to propose a cylindrical device which facilitates the collection of the agglomerate which has been removed from an infusion cavity. The device makes it easy to remove the agglomerate recovered once the tank is filled. The subject of the invention is a tank of essentially cylindrical shape capable of receiving an agglomerate discharged from a cavity of a utensil such as an infusion compartment of a coffee machine. The tank comprises a removable bottom for emptying the tank. The tank is remarkable in that it has a removable bottom of generally cylindrical shape. The device comprises means for guiding the bottom relative to the tank. These means extend radially, so that the bottom is removable in the manner of a drawer.

The guide means may preferably comprise a rail attached to the upper edge of the removable bottom, and receiving means of said rail, fixed to the tank.

The rail may advantageously comprise an upper portion of generally enlarged cross-section with respect to a lower undercut portion.

Preferably, the rail receiving means may comprise a tube having a longitudinal slot, arranged so that the tube is adapted to receive the upper portion of the rail and the slot is adapted to cooperate with the thinned region. undercut of the rail.

The reservoir and the removable bottom may preferably comprise reversible fixing means.

The reversible fixing means may advantageously comprise at least one magnet disposed on an inner surface of the tank. The magnet is arranged to cooperate with one end of the guide means when the removable bottom (33) is received by the reservoir (22). It is preferred that the guide means are made of ferromagnetic material, for example iron.

Preferably, the wall of the removable bottom may comprise a handle arranged to facilitate traction along the axis of the guide means.

It is also advantageous that the wall of the removable bottom may comprise at least one transparent region which allows inspection of the inside of the removable bottom from the outside. The invention also relates to a device for discharging an agglomerate present in the cavity of a utensil such as a brewing compartment of a coffee machine. The device comprises a reservoir capable of collecting the evacuated agglomerate and a cleaning head arranged to be rotated about its axis when a force is exerted on and towards said head, in particular by manual application of the cavity of the utensil on the head. The device is remarkable in that the reservoir is in accordance with the present invention.

Preferably, the side wall of the reservoir comprises, preferably on its outer face and / or on its upper half, fastening means adapted to allow the attachment of the device to a work plane in which the device is embedded. The invention makes it possible to exhaustively extract an agglomerate, such as an agglomerate of coffee, in a filter-holder, and to evacuate it permanently. The head of the device is configured to work when the implement is applied to the device. The device is further provided configured so that the utensil is presented returned, i.e. with its cavity facing down, which prevents any return of agglomerate forming material into the cavity since it is escapes gravitationally. The head includes cleaning means that can remove most of the agglomerate. Depending on the configurations of the head, the entire interior surface of the utensil cavity is scraped or brushed to leave it bare. Thus, the risk of pollution of the drink by previous remains is discarded. The branches of the head exploit the cohesion of the agglomerate which can be detached in blocks. Once removed from a wall, these blocks tend to leave it bare. This feature helps to heal the appearance of cleanliness of the utensil.

The tank according to the present invention which allows to contain the coffee after use, and at the same time to form a fairing collecting projections to the bottom of the tank. This feature allows to evacuate the agglomerate cleanly and quickly.

The drawer is held in a firmly installed but detachable position.

BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the present invention will be better understood from the description given by way of example and with reference to the drawings in which: FIG. 1 represents a utensil with a cavity such as a coffee machine filter holder, and an extraction device according to a preferred embodiment of the invention; Figures 2a and 2b illustrate sections of a device according to a preferred embodiment of the invention with a coffee machine filter holder; Figure 3 is a schematic view of a device according to a preferred embodiment of the invention; - Figure 4 is a schematic view of a longitudinal section at the guide means of a device according to a preferred embodiment of the invention.

Description of the embodiments

Figure 1 shows schematically an infusion compartment 2 used to prepare a volume of drink by infusion such as coffee. Infusion compartment 2 is obstructed by an agglomerate 4 of ground coffee making block. Figure 1 illustrates the curettage of the infusion compartment 2 with the aid of the invention. The infusion compartment 2 may also be used for any beverage made from a substance whose principles are extracted in contact with a liquid or vapor.

Infusion compartment 2 is a removable part of a coffee machine (not shown). It includes a handle and a filter holder 6 for receiving a dose of ground coffee. The handle facilitates the manipulation of the infusion compartment because it allows one hand to fix it on the coffee machine, and always with the same hand, to maintain it while the other hand fills it with a new dose of coffee. Commonly, the attachment of the brewing compartment 2 to the coffee machine is effected by means of a screw thread whose engagement allows in parallel to compact the ground coffee with a large force, which influences the conditions of extraction of the agglomerate.

The filter holder 6 forms a cavity containing a predefined dose of coffee. The cavity is the place where the brewing coffee is made in contact with a liquid for the preparation of the drink. The filter holder 6 has a generally cylindrical or conical shape. In its infusion orientation, in which orientation the infusion compartment is attached to the coffee machine, the filter holder 6 has an open upper face and a lower face forming the filter which is generally flat. In many configurations, the inside of the filter holder 6 tapers successively downward, so that the open upper face is wider than the lower face. The thinning is carried out in stages or continuously.

In Fig. 1, the infusion compartment 2 is shown turned upside down or upside down with respect to its infusion orientation. The open top is down. Here, the cohesion of the agglomerate 4 of coffee after use makes it possible to empty the filter holder 6 well only when its open face is downward. A device according to the invention is advantageous in that it proposes a rotating head 40 adapted to fit into the cavity of the filter holder 6, and which comprises cleaning means which rub or scrape the agglomerate 4 of coffee. The head 40 rotates about at least one axis of rotation 18. The head can be connected to a satellite itself rotating relative to the device.

Under the mechanical action of the cleaning means, the agglomerate 4 of coffee is gradually or suddenly detached from the filter holder 6. Following this detachment, the coffee falls gravitationally. As the head 40 rotates and sinks towards the bottom of the filter holder 6, the bulk of the coffee agglomerate 4 irreversibly leaves the filter holder 6. The evacuation of the fractionated agglomerated coffee takes place one way, permanently. According to the configuration of the invention, the entire coffee agglomerate 4 is irreversibly expelled from the filter holder. Thus, the filter holder 6 becomes clean and ready for a new use without risk that fresh coffee is in contact with used coffee.

It will be understood that the invention emptied exhaustively and durably the cavity of the utensil or brewing compartment 2. In particular, the returned orientation of the utensil prevents fractionated coffee from falling into it. The invention is also effective when the coffee has been particularly mechanically compressed before infusion. The arrangement of the cleaning means of the head makes it possible to improve the efficiency of the invention. The cleaning head comprises a cleaning front face. The front face comprises an annular portion adapted to retract axially against elastic forces during the insertion of the head into a portion of the receptacle with a diameter smaller than that of the end face. The front face is advantageously formed by several branches 41. According to an advantageous embodiment of the invention, the cleaning means comprise four branches 41. The branches 41 extend parallel to the axis of rotation of the head 40. branches 10 are essentially similar and implanted at the same height.

The branches form in their upper part a plane perpendicular to the direction of rotation. The upper parts extend radially and vertically. At least one branch 41 and preferably each branch 41 serves as support for at least one brush 42 which is arranged in a fixed manner. Alternatively, the brushes can be removable, which facilitates cleaning and / or replacement. The brushes 42 are aligned in a plane perpendicular to the direction of rotation. In addition, each leg 41 serves to support at least one brush 43 which is disposed on an elastic support such as a spring support. The movable brushes 43 disposed on each branch implement the retractable annular portion of the cleaning head. One of the brushes 43 is preferably arranged at the end of the branch 41 and a frame member 45 comprises the corresponding spring support. The spring support holds the brush 43 in the plane defined by the brushes 42 when no stress is applied to it. Under the action of a vertical force directed downwards in the illustrated position, the spring support allows the brush 43 to follow a vertical translational movement, parallel to the axis of rotation 18 downwards. Once the vertical stress is lifted, the brush 43 resumes its initial position in the plane defined by the brushes 42.

Alternatively, the upper parts of the branches may be fine so as to penetrate the agglomerate 4 of compacted coffee. When they sink, the upper parts split the agglomerate into blocks. Then, turning, they tear these blocks and cause their free fall. A combination of branches 41 with brushes 42, 43 and thin branches not shown is possible. The branches can exploit the cohesive property of the agglomerated coffee. Peeling the agglomerate by block allows to evacuate more quickly since the height of the blocks may be greater than the depression of the upper parts before tearing. In addition, take off a block of an inner surface 12 tends to leave clean the latter since the grains remain glued to the block and not to said surface.

Depending on the cohesion of the coffee agglomerate, the mechanical action of the cleaning means can reduce it to the state of powder. The branches 41 then form mechanical means that rust the agglomerate coffee. The action of brushes 42 and in particular brushes 43 is illustrated by the drawings in FIGS. 2a and 2b. A cleaning head 40 according to the present invention is shown in section, as well as a filter holder 6. The filter holder 6 illustrated in the drawing Fig 2a has the particularity of presenting a corner or an annular shoulder 13, which is particularly difficult to clean using known devices. Each brush 43 is mounted on a support which is capable of storing kinetic energy, such as a spring 44. Other embodiments leading to the same effect will be within the reach of those skilled in the art. Advantageously, the spring 44 is fixed on the one hand to the lower face of the brush 43 and on the other hand bears on an element 47 forming part of the frame 45. The element 47 is preferably a transverse bar. Retaining means 46 along the axis 18 are fixed to the brush. In the advantageous mode illustrated, the retaining means are formed by arms extending from the brush to the bottom of the frame 45. At their end, each arm 46 forms a tab which engages with a lower edge of the frame 45. The tabs hold the brush 43 to a maximum upper level when no vertical downward stress is applied thereto. They act against the force of the spring 44 which pushes the brush 43 upwards.

As illustrated by the drawing Fig 2b, when the cavity of the filter holder 6 is pressed on the cleaning head 40, the shoulder 13 exerts a vertical force directed downwards on the brush 43. Under the action of this force, the brush 43 is pushed down and the spring 44 is compressed. This allows the brush 43 to come into contact with the annular shoulder 13, while the fixed brushes 42 come into direct contact with the bottom of the filter holder 6. According to the arrangement of the brushes mounted on a spring support, a head cleaning device according to the present invention can marry a multitude of filter holder profiles 6 having stepwise or conical thinning towards their underside. Once the cavity of the filter holder 6 is removed, the spring 44 pushes the brush 43 upwards so that it resumes its initial position.

The bristles and the structure of the brushes 42, 43 are configured to fit into the filter holder 6. The bristles rub the agglomerate 4 of coffee, not shown in the drawings Fig 2a and Fig 2b. Their stiffness is configured to disintegrate the agglomerate of coffee. The brushes allow a certain stage of cleaning to directly rub the inner surfaces 12 and annular shoulders 13 of the cavity of the filter holder 6 to expel each coffee bean. After this friction, each grain falls from the filter holder 6 which then becomes particularly virgin of any used coffee.

The device comprises rotation means which make it possible to drive the head 40 in rotation. The head is mounted at the upper end of a shaft 18 which is connected to the support 20 of the device by means of bearings, bearings or any other equivalent means. The rotation means comprise actuating means which make it possible to control the rotation of the shaft 18 on which the head 40 is mounted.

The actuating means advantageously comprise a helical connection. The helical link connects the shaft 18 to the support 20 of the device. Helical links are well known to those skilled in the art and will not be developed further. The pitch of the helical link is greater than half the span of the head 40, the span being the maximum width of the head. Preferably, the pitch of the helical connection is greater than the span of the head 40. Choosing such a step reduces the friction in the helical connection and facilitates the conversion of a force exerted axially on the shaft 18 into a rotational movement of this shaft 18. The pitch corresponds to the distance on which the shaft 18 moves in translation when it rotates a turn on itself.

However, an excessive pitch reduces the total rotation of the head for a given translation, and reduces its efficiency as its branches 41 will sweep less intensively the inner surface 12 of the filter holder 6. At the extreme, some portions of the inner surface 12 will not be scanned. For this reason, the pitch is chosen as a function of the translation travel of the helical link and the number of branches 41. This rotation allowed by the helical connection must be greater than a fraction of a turn, this fraction being the inverse of the number of branches 41. Brought back to the helical connection, the pitch must be less than the inverse of the number of branches multiplied by the stroke allowed by the helical link. The pitch can also be determined from the number of brushes by doing a similar reasoning.

The device further comprises return means for returning the head 40 in the high position. The return means may be a spring. The stiffness of the return means also allows to exert a force resistant to the descent of the filter holder 2. The resistant force also increases the penetration of the cleaning means in the agglomerate 4 coffee. Thanks to the return means, the device also becomes active when the head 40 rises, which improves its efficiency.

This solution is advantageous because it makes it possible to operate automatically by exploiting the available sources of energy, namely the user's strength. With one hand, the user can actuate the device via the infusion compartment 2. By making a vertical back and forth movement, he rotates the head 40 of the device and evacuates the agglomerate 4 of coffee. This operation is rapid and provides adequate efficiency in the field of the preparation of drinks. According to the configurations of the cleaning means, the user can dispense with a step of checking the result.

According to an alternative embodiment of the invention, the rotation means may comprise a motor. The control means may comprise a pedal. According to this alternative embodiment of the invention, the control means may comprise a force sensor coupled to the head 40 which detects the forces applied to the head 40. If a user presses the filter holder 2 on the head 40, the latter will rotate and its cleaning means will evacuate the agglomerate 4 of coffee through its partitions.

The cleaning device is for example intended to be used in a flow of drink, The cleanliness of this place must be preserved independently of the drinks that are prepared there. For this reason, the device is provided with a reservoir 22 as shown in FIG. 3. The reservoir makes it possible to collect the agglomerate in its fall. Depending on the speed of rotation of the head 40 the coffee is projected and may reach the environment of the device. The reservoir 22 makes it possible to intercept the projections of coffee.

The reservoir 22 is intended to be inserted in a cut made in a work plane 24, next to a coffee machine. The reservoir 22 also serves as a fairing which envelops the moving parts of the device. It encircles the head 8 all along its course. The reservoir 22 has a shape that extends in the direction of translation of the helical link. The reservoir 22 has a general shape of a cylindrical profile oriented vertically. Its lower face is closed by a lower partition so as to close a storage volume in combination with the wall of the cylinder.

The reservoir 22 has an opening 26. The opening 26 is formed on its upper half. The opening 26 gives access to the head 8 from above, and allows in particular to cover it with the filter holder 6. The average level of the opening 26 is made at a height which is essentially at the level of the top of the 8, the average level of the opening 26 corresponds to the altitude of the center of gravity of a surface delimited by the contour of the opening 26. Preferably, the average level of the opening 26 is above the top of the head 8 to reduce the risk of splashes of coffee escaping from the tank 22. The opening 26 comprises a window or cutout 28 which extends from the level of the head 8 when it is in the raised position, towards the lower position of the head 8 on a height H greater than or equal to the stroke of the helical link. This window 28 further allows the insertion of the handle of the filter holder 2 and possibly a hand holding it. The width of the window 28 is reduced in order to limit the risk that splashes of coffee contaminate the surroundings of the device.

The cylindrical reservoir 22 comprises a fixed part 30 to which are connected the support 20 (FIG. 1) and the head 40, and a removable part 33 which makes it possible to empty the reservoir 22.

According to a preferred embodiment of the invention, the removable part 32 is a lower part of the reservoir which also delimits a storage volume. When this removable lower part 32 is detached from the rest of the tank 22, it allows to take the pile of used coffee. Preferably, the removable lower part 32 contains at least half of the storage volume of the reservoir 22.

The removable portion 33 is arranged in the manner of a drawer. The connection between the removable part and the fixed part 30 of the reservoir 22 is provided by means for guiding the cylindrical bottom 33 with respect to the fixed part 30. The guiding means comprise at least one rail element 34 which is arranged according to a diameter The rail protrudes from the upper edge of the cylinder 33. The rail has an upper region of circular or polygonal section and comprises an undercut lower region 36 in the vicinity of the upper edge of the portion 33. Tube 31 of section homologous to the profile of the rail is fixedly arranged in the lower part of the fixed part 30 of the tank 20. The tube comprises a longitudinal slot arranged to cooperate with the undercut region 36 of the rail. The tube 31 can receive the rail 34 by a transverse movement. Holding by the undercut region 36 ensures that the rail 34 can not emerge from the tube 31 by a vertical translation. Only a transverse movement can bring in and out the rail 34 of the tube 31.

The connection proposed between the fixed part 30 and the removable part 33 has the further advantage that waste discharged by the cleaning head 40 can fall freely to the bottom of the container 22. The tube 31 does not have a bulk at the free fall of waste.

Advantageously, reversible fixing means between the fixed part 30 and the removable part 33 of the container 22 are provided. For this purpose the inner surface portion 32 of the fixed portion 30, which is contacted by the rail 34 when the removable portion 33 is installed, advantageously comprises at least one magnet. The magnet serves to retain the metal rail, which contacts it by its end 35. The magnet holding force can be overcome by an operator who applies a pulling force of a certain intensity on the rail. The magnet may alternatively be disposed at the end of the rail 34. Other means of reversible fasteners will be known to those skilled in the art.

As illustrated by FIGS. 3 and 4, the surface of the removable portion 33 of the container 22 comprises an opening 38. The opening 38 is disposed in the axis of the rail 34, so as to facilitate the opening of the drawer 33 by pulling on the opening. Preferably protective means, such as a roof 50, protect the opening 38 on the inner side of the container. This measure prevents waste falling into the container from emerging through the opening 38. The roof preferably has a shape such that waste received in fall slide along the roof to continue their fall towards the bottom of the container 22.

Alternatively, an outer handle can be arranged on the outer surface of the removable portion, to facilitate the opening and closing of the drawer 33.

In order to inspect the contents of the container 22 and especially the level of waste collected by it, a window 39 of transparent material is disposed in the wall of the removable portion 33. When the container is full, the operator can easily remove the removable bottom of a hand and empty it, for example in a bin. The removable bottom includes the waste and empties by turning it over.

The tank and the shaft are preferably made of stainless steel, in particular because of the health constraints.
