DETAILED DESCRIPTION
(12) FIGS. 1 to 3 illustrate an embodiment of a beverage preparation machine 1 according to the present disclosure. The beverage preparation machine 1 comprises a main housing 2, a brew head 3 and a water reservoir 4. In FIGS. 1 to 3 the beverage preparation machine 1 is shown in a storage configuration. In this configuration the beverage preparation machine cannot be used to dispense a beverage.
(13) The main housing 2 comprises a base 14 having mounted thereto one or more panels forming a front face 10, two side faces 11, 12 and a rear face 13 of the main housing 2. The main housing 2 has a generally parallelepiped shape and the overall beverage preparation machine 1 has a relatively small width w.sub.1 in its storage configuration compared to its height h and depth d. In one example the width w.sub.1 is 95 mm, the height h is 260 mm and the depth d is 235 mm.
(14) The brew head 3 comprises a brew head body 30 which projects from the main housing 2. The brew head body 30 may be formed unitarily with the main housing 2 or may be otherwise mounted or connected thereto. A brew head outlet 31 is provided on a lower side of the brew head body 30 from which beverage, in use, is discharged. The brew head 3 may be configured to receive and hold one or more types of pre-packaged containers of beverage ingredients. To allow insertion and removal of the pre-packaged containers the brew head 3 may comprise upper and lower parts that can be moved relative to one another to open and close the brew head 3. The beverage preparation machine 1 may be configured to activate and commence dispensation of a beverage automatically on closure of the brew head 3.
(15) The water reservoir 4 comprises a body 40 formed from a transparent or translucent material and a base 41 to which the body 40 is fixedly mounted. The body 40 has an upper mouth 44 through which the water reservoir 4 can be filled. A dual-purpose lid 50 is provided for selectively closing the upper mouth 44 which will be described further below. The water reservoir 4 has a relatively small volume for water of up to about 700 ml. Preferably the width of the water reservoir 4 is no greater than the width w.sub.1 of the main housing 2 such that when in the storage configuration the water reservoir 4 does not extend beyond either of the two side faces 11, 12 of the main housing 2 as shown in FIG. 2.
(16) The beverage preparation machine 1 comprises a water path that extends from the water reservoir 4 to the brew head and is used to convey water during use. The water path may comprise a plurality of components including conduits, such as flexible hoses or pipes for transporting water as well as units such as pumps, heaters and valves.
(17) FIGS. 4 to 6 illustrate how the water reservoir 4 is movable to allow the beverage preparation machine 1 to adopt a beverage dispensing configuration as well as its storage configuration. In the present example, the water reservoir 4 is pivotally rotatable about a pivot point 42 located at a front corner of the main housing 2 at the junction between the front face 10 and the side face 12.
(18) FIGS. 7 and 8 show internal detail of the beverage preparation machine 1 (although some parts are omitted for clarity). As best shown in FIG. 8, the pivot mechanism of the water reservoir 4 is achieved by providing the base 41 of the water reservoir 4 with a hollow pivot pin 43 that is rotatably mounted to a hollow pivot shaft 15 of the base 14 of the main housing 2. The rotational axis of the pivot point 42 is vertical. This allows the whole water reservoir 4base 41 and body 40to be rotated to the position shown in FIG. 4. As best shown in FIG. 4, the base 14 of the main housing 2 is provided with a projecting reservoir guide leg 16 on a side of the main housing 2 opposite the pivot point 42. The reservoir guide leg 16 is shaped and sized to engage in a recess 45 formed in the base 41 of the water reservoir 4 when the water reservoir 4 is in the storage configuration. Detents may be provided on the reservoir guide leg 16 and recess 45 to allow for a click-tight connection between the two parts in the storage configuration.
(19) As shown in FIG. 8, the water path of the beverage preparation machine 1 may comprise a heater 19 and a pump 20. For reasons of clarity the interconnecting hoses (and other components such as the PCB board and control processor) have been omitted from the figure. Advantageously, the water path may extend through the pivot point 42 by utilising a flexible hose that passes within the hollow pivot pin 43 of the base 41 of the water reservoir. This permits the water reservoir 4 to be optionally non-removable from the main housing 2. In other words, the water reservoir 4 may be designed not be disconnected from the main housing 2 during use, even during refilling or emptying of the water reservoir 4. Preferably the water path, within the base 41, comprises a non-return valve to prevent reverse flow of water from the main housing 2 into the water reservoir 4.
(20) In the storage configuration of FIGS. 1 to 3 the water reservoir 4 is located at least partially beneath the brew head 3. Preferably, the water reservoir 4 is located beneath the outlet 31 of the brew head 3 and the water reservoir 4 is positioned adjacent the front face 10 of the main housing 2 so as to minimise the dimensions of the beverage preparation machine 1. It will be appreciated that in the storage configuration the water reservoir 4 is located at the front of the beverage preparation machine 1 (the front being defined as the side intended to face a user of the beverage preparation machine 1 when dispensing a beverage).
(21) When rotated to the beverage dispensing configuration, the water reservoir 4 is moved away from underneath the brew head 3 so as to create a void space 18 as shown in FIG. 4 beneath the outlet 31 of the brew head 3. The void space 18 so created allows the positioning of a receptacle to receive the dispensed beverage. This movement of the water reservoir 4 also increases the overall width of the beverage preparation machine 1 to a width w.sub.2 as shown in FIG. 6 that is greater than width w.sub.1. This increases the lateral stability of the beverage preparation machine 1 when dispensing a beverage.
(22) As noted above, the dual-purpose lid 50 may be used in the storage configuration to close the upper mouth 44 of the water reservoir 4. In the beverage dispensing configuration the dual-purpose lid 50 may be connected to the front face 10 of the main housing 2 to form a cup stand for a receptacle. To enable this, the front face 10 of the main housing 2 is provided with one or more sets of mounting points 17 for connection of the dual-purpose lid. In the illustrated example two sets of mounting points 17 are provided, each set comprising two holes that are shaped and sized to receive two L-shaped lugs 52 which extend from a rear edge of a body 51 of the dual-purpose lid 50 as shown in FIG. 4. As seen in FIG. 5, the dual-purpose lid 50 may also comprise two support webs 53 on an underside of the body 51.
(23) In use, starting from the storage configuration and with the water reservoir 4 empty, the water reservoir 4 is first rotated into the position shown in FIG. 4 so that the beverage preparation machine is in the beverage dispensing configuration. The dual-purpose lid 50 is removed from the upper mouth 44 and mounted to the desired mounting points 17 on the front face 10. Next a required amount of water is poured into the body 40 of the water reservoir 4 and a suitable receptacle is placed on the cup stand formed by the body 51 of the dual-purpose lid 50. Finally the brew head 3 is opened, a suitable pre-packaged container of ingredients is inserted and the brew head 3 closed. Closure automatically initiates the brew cycle and dispensation of a beverage. Said brew cycle involves operation of the pump 20 and heater 19 to convey water from the water reservoir 4 via the water path to the brew head 3 while at the same time heating the water to the required temperature. Once dispensation has been completed the beverage preparation machine 1 may be returned to the storage configuration in order to minimise worktop (or storage) space until next required.
(24) FIGS. 9 and 10 illustrate an alternative design of dual-purpose lid 50 which may form part of the beverage preparation machine of the present disclosure. In the following, like components to those previously described have been referenced using like reference numerals. In the same way as described above the dual-purpose lid 50 may be used in the storage configuration to close the upper mouth 44 of the water reservoir 4 and in the beverage dispensing configuration the dual-purpose lid 50 may be connected to the front face 10 of the main housing 2 to form a cup stand for a receptacle. As before, the dual-purpose lid 50 is provided with two L-shaped lugs 52 which extend from the rear edge of the body 51 of the dual-purpose lid 50 as shown in FIG. 9 and which engage in use with the desired mounting points 17 on the front face 10. As above, the dual-purpose lid 50 may comprise two support webs 53 on the underside of the body 51. An upper side of the body 51 is not flat as above but instead comprises a receptacle 60 for collection of liquid over-spilling in use from a receptacle or dripping from the outlet 31. The receptacle 60 is defined by a base wall 61, an upstanding side wall 62 and a flange 63 of the body 51. The receptacle 60 is preferably shallow with the upstanding side wall 62 only having a height in the range of 2 to 12 mm. Consequently, the volume of liquid able to be held by the receptacle 60 is small and in the range of 6 to 15 ml and is primarily intended to catch and hold drips at the end of a single brew cycle and not to retain large quantities of fluid in the eventuality that the receptacle is removed from the dual-purpose lid 50 before the end of the brew cycle. In use, the dual-purpose lid 50 is intended to be emptied and washed after each use and before reverting the beverage preparation machine into the storage configuration. Thus, having a small volume for the receptacle 60 is adequate and has the advantage that the depth of the dual-purpose lid 50 can be kept small.
(25) The receptacle 60 is sub-divided into a plurality of segments by a series of ribs 64 which extend upwardly from the base wall 61. The ribs 64 run radially inwardly from the upstanding side wall 62 towards a centre 65 of the dual-purpose lid 50 but stop short of meeting with one another. An upper free edge of the ribs 64 forms a plurality of support points for the receptacle in use such that the receptacle is held clear of the base wall 61. In this way the dual-purpose lid 50 is enabled to function as a cup stand when mounted to the front face 10. The ribs 64 also function to stiffen and strengthen the dual-purpose lid 50.
(26) Preferably the base wall 61 of the receptacle 60 is un-apertured. In other words no drainage point is provided in the base wall 61, for example at the centre 65. This is advantageous since the dual-purpose lid 50 must function as a lid of the water reservoir 4 and being un-apertured allows for better closure of the water reservoir 4. Consequently, the dual-purpose lid 50 may be simply emptied and cleaned by upending the dual-purpose lid 50 and draining any liquid through the open mouth of the receptacle 60.
(27) In other respects the dual-purpose lid 50 functions as described above.
(28) FIG. 11 illustrates an alternative design of a beverage preparation machine 1 of the present disclosure. In the following, like components to those previously described have been referenced using like reference numerals. In most respects the design and function of the beverage preparation machine 1 is the same as the design described above and will not be discussed further. However, in this alternative design the brew head 3 is shaped differently and comprises an angled front face 32 that also forms a handle by which the brew head 3 can be grasped and pivoted upwards to open the brew head 3 to allow insertion of a beverage cartridge. In addition, the base 41 of the water reservoir 4 illustrates the optional feature wherein the body 40 of the water reservoir 4 may be detached from the base 41. Preferably the base 41 is provided with a plurality of upstanding guide projections 47 which assist in guiding the sliding connection of the body 40 to the base 41 and may also help to retain the body 40 on the base 41 by suitable means, for example an interference frictional fit or a snap-fit connection.
