Description

FIELD OF THE INVENTION

The present disclosure is in the field of beverage preparation systems.

BACKGROUND

An espresso machine brews coffee by forcing pressurized water near boiling point through a condensed pack of ground coffee and a filter in order to produce a thick, concentrated coffee called espresso. A single-serve coffee container, also referred to as a capsule, is a type of coffee container used in coffee brewing for preparing only enough coffee for a single portion.

Use of capsules can both reduce the time needed to brew coffee and simplify the brewing process by eliminating the need to measure out portions, flavorings, and additives from large bulk containers. The capsules can also help keep the unused product fresh by individually packaging portions separately without exposing the entire supply batch to air and light.

Commercially available systems are normally provided in the form of a counter top device, such as may be used in private homes and small offices, and somewhat larger systems, such as the Nespresso® machines seen at https://www.nespresso.com/pro/n1/en/professionele-koffiemachine.

DETAILED DESCRIPTION

Disclosed herein is a bifurcated beverage preparation system, denoted in the drawings by reference numeral 90, according to certain exemplary embodiments. The aspect in which the system is bifurcated, is the separation of the beverage preparation and dispensing components, on the one hand, embodied herein and shown in the drawings as beverage preparation head 100, mounted on a faucet 105 by a mounting element 104; and the liquid supply and system operation components, on the other hand, embodied herein and shown in the drawings as hydraulic operating unit 150. This separation facilitates the integration of the system with a conventional counter-top type faucet, taking up minimal “above counter” space in the vicinity of the faucet, while the system operation components are stored beneath the counter.

Definition: The terms “liquid” and “water” are used in the present specification. In a sense, they are used interchangeably, as the system is intended to use any liquid of choice, this being the case whether such liquid forms part of a beverage or part of the hydraulic components of the system. In the examples detailed below, however, the liquid of choice is water although, as mentioned above, this is not intended to exclude use of the present system with other liquids.

As will be seen with reference to FIGS. 1A and 1B, and as mentioned above, bifurcated beverage preparation system 90, is composed of beverage preparation head 100, having a housing 101 mounted as by schematically illustrated mounting element 104 onto faucet 105; and a hydraulic operating unit, referenced generally 150, mounted typically under-counter, referenced generally 118, remotely from housing 101 and faucet 105.

Housing 101 includes a liquid inlet 116 and a delivery spout 112 to facilitate outflow of a prepared beverage. Housing 101 includes therein a beverage preparation head 102 having a capsule compartment 106 configured to hold a beverage capsule 110 during preparation of a beverage. It is appreciated that beverage capsule and capsule are used interchangeably herein to refer beverage capsule 110.

Beverage capsule 110 can generally have a frustoconical side wall 111 formed of a rigid material, such as plastic, aluminum and/or the like, which terminates in a second sealed end 121 so as to form a volume for containing a predetermined volume of a flavoring agent, and a first sealed end 120 sealed by a frangible film 122. Beverage preparation head 102 includes a retractable holder 108 for positioning beverage capsule 110 along a liquid flow path (not shown) extending between liquid inlet 116 and delivery spout 112, such that opening of capsule 110 at both ends 121 and 120, as described hereinbelow in detail, and then streaming liquid therethough so to cause flavor to be imparted to the through flowing liquid, produces the beverage. In certain exemplary embodiments, a plurality of retractable holders 108 can be inserted into beverage preparation head 102 thereby facilitating the use of a plurality of differently sized and shaped beverage capsule with beverage preparation system 90.

As seen in FIG. 1B, and as described in more detail below in conjunction with FIGS. 8A-8D, mounting element 104 is configured to mount housing 101 of beverage preparation head 100 onto faucet 105 between a faucet base 115 and a faucet spout 113. Receptacle 135 is positioned on a beverage receptacle tray 137 in alignment with delivery spout 112 to receive an outflow of the beverage 136 from delivery spout 112.

Referring now to FIG. 2, there is provided a hydraulically operated plunger 231 which, in cooperation with a stationary bottom surface 243 of capsule compartment 106, forms a pressurized beverage preparation chamber, in which the contents of a capsule positioned therein is exposed.

As seen clearly in the drawing, hydraulically operated plunger 231 has several downward facing puncturing elements 232 which extend in a downward direction. As hydraulically operated plunger 231 is moved downward so as to enclose capsule 110, the tips of downward facing puncturing elements 232 engage and pierce second sealed end 121. In the illustrated embodiment, downward facing puncturing elements 232 are seen to be angled inwardly towards an axis of motion 250 of hydraulically operated plunger 231. Accordingly, as they continue moving downwardly so as to enter the interior of capsule 110, they tear longitudinal openings 245 in the second sealed end 121 thereof. At this time, as hydraulically operated plunger 231 descends further, such that frangible film 122 engages with bottom surface 243 so as to completely seal capsule compartment 106, the first sealed end 120 of capsule 110 is pushed against jagged surface 240, such that its protrusions 241 perforate frangible film 122.

In certain embodiments, hydraulic piston 235 positions capsule 110 on top of bottom surface 243 without perforating frangible film 122. As hot liquid is directed into capsule 110, pressure within capsule 110 increases thereby pushing frangible film 122 against jagged surface 240, such that its protrusions 241 perforate frangible film 122.

Pressurized liquid is then introduced into capsule compartment 106 via a plunger conduit 234 formed in hydraulically operated plunger 231. The liquid enters into the interior of capsule 110 via the openings formed in second sealed end 121 of capsule 110, through the capsule and the flavoring agent contained therein, subsequently exiting through the perforated frangible film 122 at first sealed end of the capsule 110.

Referring to hydraulic operating unit 150 that is in liquid communication with a liquid inlet 116 via source conduit 202. Source conduit 202 directs liquid from liquid inlet 116 to a pressure regulator 204, which maintains the liquid pressure of the liquid directed to a pump 145 via pump hose 206. A pressure regulator monitor 205 can be in liquid communication with pump hose 206 to facilitate monitoring of the liquid pressure. In certain optional exemplary embodiments, hydraulic operating unit 150 can include a liquid tank 140 for storing liquid that can be used for beverage preparation when no liquid is provided by liquid inlet 116, for example, when beverage preparation system 90 is disconnected from liquid inlet 116. In some embodiments, liquid tank 140 is in fluid communication with pressure regulator 204 and source conduit 202 through tank conduit 203.

Pump 145, which, for example, may be a vibratory pump, for pumping water to hydraulically operated plunger 231 thereby actuating hydraulically operated plunger 231. Pump 145 pumps the liquid through a split line 207, a hydraulic valve 209 and a hydraulic hose 220 to hydraulically operated plunger 231 as described in conjunction with FIG. 2. Hydraulically operated plunger 231 includes a hydraulic piston 235 having a piston 236, one or more hydraulic springs 238 and a liquid chamber 237. Liquid chamber 237 is filled with the pumped liquid such that as it is filled, pressure builds in liquid chamber 237 thereby actuating a bottom panel 239 downwards onto a top end of piston 236. As bottom panel 239 applies force onto piston 236, piston is actuated to apply a relatively same force onto hydraulically operated plunger 231 resulting in its downward movement.

Pumping of water thereby actuating hydraulic piston 235 is operative to move downward facing puncturing element 232 towards an bottom surface 243, thereby to cause puncturing of second sealed end 121 and rupture of first sealed end 120, whereupon liquid pumped by pump 145 to liquid inlet is forced through longitudinal openings 245 formed in both ends of capsule 110 so as to mix with the flavoring agent therein so as to form beverage 136, thereafter flowing out of beverage preparation head 102 via delivery spout 112. In certain embodiments, bottom surface 243 prevents the passage of grains from capsule 110 into delivery spout 112. Hydraulic operating unit 150 includes a hydraulic solenoid valve 221 configured to facilitate drainage of the liquid used to actuate said hydraulically operated plunger 231, upon completion of the beverage preparation. The liquid is drained from liquid chamber 237 and directed to a disposal outlet 225 via hydraulic hose 220 and a dispensing conduit 222. As the liquid is drained from liquid chamber 237, hydraulic spring 238 pushes bottom panel 239 upwards into liquid chamber 237 thereby pulling hydraulic piston 235 and hydraulically operated plunger 231 upwards away from capsule compartment 106.

Pump 145 is further operative to pump liquid through split line 207 to a first beverage valve 208 and a temperature pipe 218 to a liquid temperature controller 211. Liquid temperature controller 211 changes the temperature of the liquid to a predetermined temperature desired for beverage preparation. In one optional exemplary embodiment, liquid temperature controller 211 can include a heater 212 and a heating tank 213 for heating the water to a predetermined temperature. Liquid temperature controller 211 can include a temperature sensor 265 to facilitate regulating the predetermined temperature. From liquid temperature controller 211 the liquid is directed through a first beverage pipe 214, a second beverage valve 215, a second beverage pipe 217 and a sealing plunger conduit 234 to capsule compartment 106. At capsule compartment 106, the liquid is supplied at the predetermined temperature and the predetermined pressure through beverage capsule 110 thereby delivering an outflow of a flavored beverage via beverage delivery spout 112, substantially as described above.

Hydraulic operating unit 150 includes a beverage solenoid valve 223 operative to facilitate drainage of residue liquid and materials from within capsule compartment 106 to disposal outlet 225. The residue liquid is drained through second beverage pipe 217, dispersal conduit 216 and dispensing conduit 222 as described in conjunction with FIG. 2.

Beverage system 90 includes an activation button 270, connected to a controller 260, and operative to activate controller 260, which is configured to automatically operate pump 145, first beverage valve 208, second beverage valve 215, beverage solenoid valve 223, hydraulic valve 209 and hydraulic solenoid valve 221 to prepare beverage 136 as described in conjunction with FIG. 2.

In certain exemplary embodiments, first beverage valve 208, second beverage valve 215 and hydraulic valve 209 are one-way valves that are not operated by controller 260. First beverage valve 208, second beverage valve 215 and hydraulic valve 209 each have a spring that is calibrated to allow liquid flow through each valve when a predetermined liquid pressure is applied to each valve, thereby controlling the flow of liquid through beverage preparation system 90.

Maintaining beverage solenoid valve 223 open prevents the cold water in first beverage pipe 214 and second beverage pipe 217 from reaching capsule 110, by directing all cold water to disposal outlet 225. In certain embodiments, first beverage valve 208 (FIG. 2) and second beverage valve 215 (FIG. 2) prevent water from flowing according to the tension calibration of the spring in the valve, to ensure the proper pressure buildup of the liquid. In certain embodiments, controller 260 can actuate first beverage valve 208 (FIG. 2) and second beverage valve 215 (FIG. 2) into a closed state to prevent water from initially flowing to capsule compartment 106 (FIG. 2).

Step 310 discloses activating pump 145. Controller 260 actuates pump 145 to pump water through hydraulic operating unit 150, which in its present configuration results in liquid being pumped to hydraulically operated plunger 231 to seal capsule compartment 106 and puncture beverage capsule 110 as described above in conjunction with FIG. 2. As water is pumped to hydraulically operated plunger 231, water pressure builds in split line 207, until the water pressure is sufficient to open first beverage valve 208 thereby allowing the water to pass through into first beverage pipe 214.

Step 312 discloses waiting for hydraulic operated plunger 231 to engage. Controller 260 is configured to count a predetermined time during which hydraulic operated plunger to reach capsule 110.

In some embodiments, where controller 260 operates first beverage valve 208 and hydraulic valve 209, optional step 315 discloses opening first beverage valve 208 and second beverage valve 215, and closing hydraulic valve 209.

Step 316 discloses waiting for hot water to run through disposal outlet, thereby removing all cold water from first beverage pipe 214 (FIG. 2) and a second beverage pipe 217 (FIG. 2).
