The field of the invention pertains to beverage machines, in particular to the ability to displace such machines and to adjust the appearance of the machine to its environment and/or its functional versatility to match the preferences of different users.
For the purpose of the present description, a “beverage” is meant to include any liquid food, such as tea, coffee, hot or cold chocolate, milk, soup, baby food, etc. . . .
Certain beverage preparation machines use capsules containing ingredients to be extracted or to be dissolved; for other machines, the ingredients are stored and dosed automatically in the machine or else are added at the time of preparation of the drink.
Most coffee machines possess filling means that include a pump for liquid, usually water, which pumps the liquid from a source of water that is cold or indeed heated through heating means, such as a heating resistor, a thermoblock or the like.
Such machine typically have a brewing unit for holding and extraction the beverage ingredient. To introduce the ingredient into the brewing unit and then remove the ingredient upon use, the brewing unit has a closure mechanism that may be driven by a handle that is operable by a user.
EP 1 208 782 discloses a coffee machine having a main body including a brewing unit for extracting coffee capsules. The brewing unit is opened and closed with the aid of a handle that can be turned over the main body by an angle of about a 180 deg. from behind to the front of the main body. The handle has a pair of generally L-shaped levers connected at one end by a hand-drivable transverse rod and pivotally mounted at the opposite end to the opening and closing mechanism of the brewing unit. The pivotable L-shaped levers drive a movable part of the brewing unit via a pair of intermediate levers connected at a first end to this movable brewing unit part and at a second end to the corner of the L-shaped levers.
US 2008/0006159 discloses a brewing unit for an undisclosed coffee machine body. The brewing unit has a horizontally movable drawer for introducing an ingredient pouch and a vertically movable top part with a piercing mechanism for opening the pouch. These elements are driven by a generally U-shaped movable handle that can be pivoted from an upright open position down to a generally horizontal closed position.
U.S. Pat. No. 7,165,488, WO 2007/111884 and EP 1 829 469 disclose a beverage machine having a main body with a foot extending in front of the machine for supporting a cup to be filled with beverage as well as an overhanging brewing unit above this foot. The brewing unit can be opened and closed manually by means of a handle system that is linked to a movable top part of the brewing unit and indirectly to a top front part of the main body.
Such machines are usually arranged to be placed at some convenient location on a support surface in a kitchen or bar or in an office or in another suitable environment, typically close to the mains and to a source of water, in particular close to the kitchen sink, and are not easily movable. This is inconvenient when the machine or the supporting surface needs to be cleaned or the machine otherwise moved, e.g. to a different room. When this happens, the user tends to seize the machine wherever he manages to find some gripping means, e.g. at the outlet nozzle, at the drip tray, by the machine's opening for the drip tray or waste ingredient container, under the machine's bottom . . . in an unreliable manner which may lead to dropping the machine, damaging parts of the machine exposed to excessive mechanical stress due to seizure of the machine at improper locations, to the falling out/off of some movable parts of the machine, such as the already mentioned drip tray, waste ingredient collector or even the water reservoir.
Moveable coffee machine are already known. EP 1 878 368 discloses a beverage machine having a functional block that is rotatably mounted on a support base. The functional block can be designed to be removable from the support base. EP 1 864 598 discloses an autonomous beverage machine that can be mounted onto a docking station. The beverage machine is arranged to be operable whether connected to the docking station or disconnected therefrom.
However, there is still a need to provide a coffee machine arranged so that is can be easily lifted and/or carried around by a user, in particular single-handed, and moreover, a machine whose appearance may be adjusted to fit different environments.
It is a preferred object of the present invention to provide a beverage preparation machine with a simple arrangement for allowing a user to displace safely the machine.
The invention thus relates to a machine for preparing a beverage, in particular from a pre-portioned ingredient such as an ingredient supplied to such machine within a capsule.
For instance, the machine is a coffee, tea or soup machine, in particular a machine for preparing within an extraction unit a beverage by passing hot or cold water or another liquid through a capsule or pod containing an ingredient of the beverage to be prepared, such as ground coffee or tea or chocolate or cacao or milk powder.
The machine comprises a main body containing a brewing unit for housing this ingredient.
Typically, main body includes one or more of a pump, heater, drip tray, ingredient collector, liquid tank and fluid connection system for providing a fluid connection between the liquid tank and the brewing unit, etc. . . . . The configuration of a fluid circuit between the liquid reservoir and a heater for such a machine is for example disclosed in greater details in co-pending application PCT/EP08/067,072.
The machine further comprises a handle movable, in particular pivotable, relative to the main body, so as to act on the brewing unit to open the brewing unit for introduction or removal of this ingredient into and from the unit, and act to close the brewing unit for extraction of this ingredient within the unit. The movable handle has a gripping part and is arranged to be drivable by a human hand.
In accordance with the invention, the main body and the movable handle are so connected and configured that the gripping part has a carrying position in which the gripping part is seizable by such human hand for safe lifting and displacing of such machine single-handed.
This handle and main body should be so arranged that the entire weight of the main body can be supported by the handle without risk of damage or deformation of the machine, as might for instance happen if a user pulls a machine by seizing an apparent component such as a beverage outlet, an electric cable or a handle closing or opening the brewing unit or prior art handles on machines that have not been structurally configured for this purpose. The size and shape of the gripping part should be adapted to the shape and capacity of a normal human hand to allow a firm seizure by the hand, sufficient for the user to safely carry the machine with all its weight single-handed via the gripping part. Optionally, the gripping part includes a means, such as a surface structure or composition, in particular an anti-skid surface that provides friction against a human hand to reduce the necessary gripping force needed to achieve a reliable gripping.
Hence, the machine of the invention provides a simple handle for the user to operate the machine, for opening and closing the brewing unit, and lift and/or displace the machine.
The ability to lift a machine single-handed allows for instance to lift the machine with one hand wipe and clean the supporting surface, e.g. a table, with the other hand and replace the machine, in a single operation.
The machine typically has an operative orientation, e.g. when placed on a table or other horizontal surface, for dispensing beverages. The machine would also have a corresponding carrying orientation when lifted single-handed by the gripping part of the handle. In this case, the carrying orientation can be inclined relative to the operative orientation by a tilting angle of less than 30 deg, such as in the range of 1 to 10 or 20 deg, the carrying orientation being in particular identical to the operative orientation. When the carrying orientation is inclined in such a manner, it means that the machine when lifted is slightly tilted with respect to its operative orientation. Different tilting angles for the same machine may for instance result from the presence in the machine's main body of liquid or ingredient reservoirs whose state of filling affect the position of the centre of gravity of the machine.
For instance, the main body has a foot or bottom face for resting on a generally parallel horizontal external support surface, such as a table. In this case, the gripping part of the handle in its carrying position and the centre of gravity of the machine's body can be vertically aligned, perpendicularly to the foot or bottom face, in which case the machine is not tilted when lifted via the handle. Alternatively, the gripping part of the handle in its carrying position and the centre of gravity of the machine's body can be at a tilting angle of less than 30 deg thereto, such as in the range of 1 to 10 or 20 deg to a perpendicular direction to the foot or bottom face of the machine.
Typically, the handle can be pivotally mounted on the main body about a pivoting axis, in particular a pivoting axis fixed relative to the main body. It is also possible to provide a handle with a translation movement.
The machine's centre of gravity, the gripping part in its carrying position, and the pivoting axis can be generally coplanar or aligned, or form a tilting angle of less than 25 deg, in particular in the range of 1 to 10 or 15 deg, with the gripping part as vertex.
The machine's centre of gravity may be displaced when the gripping part is moved into its carrying position from a position distant thereof, so as to minimise the tilting angle.
The handle may act on the brewing unit to move at least a part thereof towards or away from the gripping part, when the gripping part is moved into the carrying position, whereby the centre of gravity is displaced. Hence, the movement of the movable part of the brewing unit can be advantageously configured so that the centre of gravity of the machine is displaced to an optimal place for lifting and/or displacing single-handed the machine, e.g. underneath the gripping part of the handle or closely thereto leading to minimal or no tilting of the machine when lifted.
Typically, the handle may form half a loop around a part of the main body, in particular around a top part of the main body, the gripping part being usually a middle part of the loop. The handle can be generally U-shaped or arched or semi-circular or semi-elliptic, the handle being in particular pivotally mounted at two extremities thereof onto the main body.
In one embodiment, the handle is pivotable about a top part of the machine's main body, in particular from above the top part to an upper front or upper rear side portion of the main body, typically adjacent the machine's beverage outlet. For instance, the brewing unit has a movable part that is telescoped out of the body when the gripping part of the handle is in its carrying position, and that is retracted into the body when the brewing unit is closed and the gripping part is in a beverage extraction position. Optionally, the gripping part in the beverage extraction position and the movable part of the brewing unit when opened are at an identical location. In this case, when the gripping part is moved into the extraction position to close the brewing unit, the movable part of the brewing unit is retracted into the machine's main body and the handle's gripping means takes the place freed by the movable part of the brewing unit. Such an embodiment leads to minimising the space needed for operating the machine and to a machine that is better balanced about its handle when lifted and/or displaced by holding single-handed the machine by the handle.
Typically, the gripping part of the handle in its carrying position is arranged to accommodate for seizure by at least three or four fingers of a human hand. Hence the user may firmly and safely seize the gripping part to lift and displace de machine single-handed.
Usually, the main body includes one or more removable parts, such as removable parts selected from a drip tray and a liquid receptacle and used ingredient receptacle and an ingredient supply device, the removable parts being so secured in the body and/or the body having such an orientation during lifting and displacing, that all the removable parts remain safely in place relative to the body when such machine is displaced single-handed.
Another aspect of the invention concerns a machine for preparing a beverage, in particular as described in above. Moreover, the machine according to this aspect of the invention may include any feature or combination of features of the above described machine.
The machine of this aspect of the invention comprises a main body containing a brewing unit for housing an ingredient, in particular a pre-portioned ingredient such as an ingredient supplied to such machine within a capsule. Furthermore, the main body has an outermost casing. The machine further includes a handle having two facing connection extremities pivotally connected to the brewing unit via corresponding pivotable axles, so as to act on the brewing unit to open the brewing unit for loading and/or unloading this ingredient into and from the unit, and so as to act to close the brewing unit for extraction of this ingredient within the unit.
In accordance with the invention, the handle extends outside the main body from one side to a facing opposite side of the outermost casing and is connected to the brewing unit via the pivotable axles through the facing opposite sides of the outermost casing, the handle extending in particular around facing lateral walls.
By providing such a configuration of the handle and the machine's main body, in particular the pivotable axles connecting the handle to the brewing unit via the casing, the body's casing may extend and shield the main body nearby the handle and requires only two small holes for allowing the passage of the axles. In contrast, when lever portions of the handle extend through the casing, large openings are required in the casing for allowing displacements of the lever portions of the handle through and along the casing.
Furthermore, such a handle extending around the facing sidewalls may be used to secure or contributes to secure these sidewalls together and simplify the assembly arrangement of the casing.
A further aspect of the invention relates to a machine for preparing a beverage, in particular a machine as defined above. The machine has: a main body comprising at least part of a fluid system for preparing a beverage from an ingredient housed in a brewing unit, in particular a pre-portioned ingredient such as an ingredient supplied to such machine within a capsule; and an outermost casing for containing and shielding the main body. In accordance with the invention, the casing comprises at least one panel that is detachably mounted onto the main body or to further parts of the casing by connection means that are accessible and connectable and disconnectable by a user to remove and substitute the panel by another compatible panel.
Typically, the user may be provided with a set including this machine with a casing that comprises such a panel as well as a plurality of separate different compatible panels for substituting the panel. Hence, different kinds of compatible panels may be made available to the user in order to enable him to change the machine's appearance and adjust it to a different location, e.g. a different room.
For instance, a user may want to have the machine's appearance aligned to a kitchen of a certain colour, e.g. brown, and thus have a beverage machine of the same or compatible colour, e.g. brown, red or beige. If the user wants to move his beverage machine into a different room, e.g. dining room or living room having a colour arrangement, e.g. greenish, that is different to his kitchen, he may want to adjust the appearance of his beverage machine and exchange the panels with panels of a different colour, e.g. green or turquoise. Some users may also want to have machines with a flashy, possibly multi-colour, appearance and mount corresponding panels. Other users may want to have visual access inside the machine and thus mount transparent panels.
Moreover, various different compatible types of panels may be configured to provide different functions. For instance, one type of panel may be provided merely to dress the beverage machine. Another type of panels may be provided with one or more laterally and/or generally horizontally extending support members e.g. for accessories, such as cups, spoons, cream, sugar, etc. . . . For example, a support member is dedicated for cups and has an integrated heater for pre-heating the cups. The heater may be electrically powered by the electric circuit of the machine via a plug and socket system in the panel and the inside of the beverage machine. Hence the functional versatility of the machine may be increased to match the preferences of different users.
Hence, the machine and set of the present invention provide the user with great flexibility as to the appearance of the machine and adjusting possibilities to fit the taste of the user. This flexibility and adjustment possibilities are simple, inexpensive and do not involve the need to acquire a whole new machine or return the machine to a professional retrofitter.
A yet further aspect of the invention relates to a machine for preparing a beverage, in particular as described above. The machine has: a main body containing at least part of a fluid system for preparing a beverage from an ingredient housed in a brewing unit, in particular a pre-portioned ingredient such as an ingredient supplied to such machine within a capsule; and an outermost casing for containing and shielding the main body. In accordance with the invention, the casing comprises at least one side panel that has a horizontally extending member for supporting accessories, the horizontally extending member being optionally retractable in particular in a vertical position and/or provided with a heater for preheating cups.
The invention will now be described with reference to the schematic drawings, wherein:

A translational closure mechanism is associated with brewing unit 1 to open and close it along a straight line 3′ in a telescopic manner. The closure mechanism of such a beverage machine is discussed in greater details in co-pending application PCT/EP08/060,463, the priority of which is claimed and the content of which, in particular relating to its
Brewing unit 1 comprises a capsule holding assembly with a beverage outlet 14 forming a first movable assembly 3 and a water injection assembly with a water inlet or line forming a second fixed assembly 2. Each assembly 2,3 delimits at least part of a brewing chamber 7′ for containing an ingredient capsule. In a variation, the capsule injection assembly may be movable and the capsule holding assembly may be fixed or movable.
Holding assembly 3 has a generally tubular cover 11 and is movable away from the cooperating injection assembly 2 into an open position, as shown in
By moving holding assembly 3 against the injection assembly 2 into the closed position, as shown in
Hence, the machine has an outermost casing 80 and one of its brewing unit assemblies 2,3 can be moved or telescoped out through casing 80 for inserting/removing an ingredient capsule, and can be retracted into outermost casing 80 for bringing brewing unit 1 into its capsule extraction or brewing configuration.
Underneath brewing unit 1, casing 80 has a cavity 85 for receiving a removable receptacle 86. The front part of cavity 86 is delimited by side panels 80′. Brewing unit 1 and receptacle 86 are so arranged that passage 22 has a lower opening giving into receptacle 86. Hence, when brewing unit 1 is reopened after extraction, the used capsule drops into receptacle 86. Holding and positioning mechanisms for the insertion and removal of the capsule in such a brewing unit are for example disclosed in EP 1 646 305 and EP 1 859 714.
Hence, holding assembly 3 is movable with its tubular cover 11 in translation along a straight direction 3′ from the closed position to the open position and vice versa so as to open passage 22 for the insertion of a capsule, close brewing unit 1 for the extraction of the capsule therein and reopen passage 22 for the evacuation of the capsule therefrom into receptacle 86.
Receptacle 86 is positioned on a drip tray arrangement 87 for supporting a cup under beverage outlet 14 and for collecting drips and spills. Receptacle 86 and drip tray arrangement 87 may be inserted and removed en bloc into and from cavity 85. Suitable embodiments of such drip tray and receptacle arrangements are for example disclosed in EP 1 867 260.
Brewing unit 1 further includes a capsule handling assembly 3 which comprises a main body portion 15 having an upper passage 22 with an opening 22′ for inserting the capsule in a capsule cage 7. A puncturing plate 13 is lodged inside and in the front of body portion 15. On the front side of body portion 15 is provided a beverage delivery duct 19 for delivering the beverage from the capsule cage 7 via the puncturing plate 13 to a receptacle (e.g., a cup) via outlet duct 14 of tubular cover 11.
Water injection assembly 2 is mounted in the capsule handling assembly 3 in a linearly moveable fashion via two lateral pins 20, 21 placed on each side of the guide support 6 which respectively engage a pair of guiding slots 221, 222 provided on the side of the handling assembly 3. The pins 20, 21 are directly linked to a lever assembly 30, 31, 32. The lever assembly is axially connected along a transversal axis 34 to the pins 20, 21. The lever assembly has a U-shaped handle 30 and two guiding rods 31, 32. Handle 30 is connected via its extremities 30″ to axles 31′,32′ of rods 31,32 along axis 34. Rods 31,32 prolong the handle beyond the axis 34 in a linear direction with small interior pins 35, 36 which slide along downward extensions 23, 24 of the slots. Handle 30 has a middle gripping part 30′ arranged to be driven by a human hand 10 and a pair of connection extremities 30″ linked via levers 30′″ for amplifying the transmitted force from hand-driven gripping part 30′ to rods 31,32.
Closure of brewing unit 1 is obtained by handling and pulling handle 30 down in the position of
