Máquina de bebidas con depósito de agua ergonómico..

FIELD OF THE INVENTION

[0001] The field of the invention pertains to beverage preparation machines provided with an ergonomic water storage, e.g. machines using capsules of an ingredient of the beverage to be prepared.

[0002] For the purpose of the present description, a “beverage” is meant to include any human-consumable liquid substance, such as tea, coffee, hot or cold chocolate, milk, soup, baby food, etc... A “capsule” is meant to include any pre-portioned beverage ingredient, such as a flavouring ingredient, within an enclosing packaging of any material, in particular an airtight packaging, e.g. plastic, aluminium, recyclable and/or biodegradable packagings, and of any shape and structure, including soft pods or rigid cartridges containing the ingredient. The capsule may contain an amount of ingredient for preparing a single beverage portion or a plurality of beverage portions. BACKGROUND ART

[0003] Certain beverage preparation machines use capsules containing ingredients to be extracted or to be dissolved and/or ingredients that are stored and dosed automatically in the machine or else are added at the time of preparation of the drink. Some beverage 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, e.g. a thermoblock or the like.

[0004] Especially in the field of coffee preparation, machines have been widely developed in which a capsule containing beverage ingredients is inserted in a brewing device. The brewing device is tightly closed about the capsule, water is injected at the first face of the capsule, the beverage is produced in the closed volume of the capsule and a brewed beverage can be drained from a second face of the capsule and collected into a receptacle such as a cup or glass.

[0005] Ingredient mixing modules, e.g. brewing devices have been developed to facilitate insertion of a “fresh” capsule and removal of the capsule upon use. Typically, the brewing devices comprise two parts relatively movable from a configuration for inserting/removing a capsule to a configuration for brewing the ingredient in the capsule. The actuation of the movable part of the brewing device may be manual as disclosed in WO 2009/043630, WO 01/15581, WO 02/43541, WO 2010/015427, WO 2010/128109, WO 2011/144719 and WO 2012/032019. Various handle configurations are disclosed in EP 1867260, WO 2005/004683, WO WO2007/135136, WO 2008/138710, WO 2009/074550, WO 2009/074553, WO 2009/074555, WO 2009/074557, WO 2009/074559, WO 2010/037806, WO 2011/042400, WO 2011/042401 and WO 2011/144720. Integrations of such arrangements into beverage machines are disclosed in WO 2009/074550, WO2011/144719, EP2014195046, EP2014195048 and EP2014195067. The actuation of the movable part of the brewing device may be motorized, as for example disclosed in EP 1 767 129, WO 2012/025258, WO 2012/025259 and WO 2013/127476.

[0006] A beverage machine typically includes a housing containing a beverage processing module and a water tank in fluid communication with the beverage processing module. Examples of such beverage machines are disclosed in EP 1 208 782, EP 1 267 687, EP 1 686 879, EP 1 731 065, EP 1 829 469, EP 1 864 598, EP 1 865 815, EP 1 867 260, EP 1 878 368, EP 2 222 210, EP 2 222 211, EP 2 222 212, EP 2 227 121, EP 2 227 122, US 2008/0006159, U.S. Pat. No. 7,165,488, WO 2007/111884, WO 2009/074553, WO 2010/015427, WO 2011/089210 and WO 2012/055767. Usually the water tank is removable to be refilled by a user when empty. Some systems include a continuous water supply by connecting the beverage machine to the city water distribution network, as for instance disclosed in CN201076369, PCT/EP15/065409, PCT/EP15/065410, PCT/EP15/065411 and PCT/EP15/065414. SUMMARY OF THE INVENTION

[0007] The invention relates to a machine for preparing a beverage. The beverage preparation machine can be an in-home or out of home machine. The machine may be for the preparation of coffee, tea, chocolate, cacao, milk, soup, baby food, etc...

[0008] The beverage preparation typically includes the mixing of a plurality of beverage ingredients, e.g. water and milk powder, and/or the infusion of a beverage ingredient, such as an infusion of ground coffee or tea with water. One or more of such ingredients may be supplied in loose and/or agglomerate powder form and/or in liquid form, in particular in a concentrate form. A carrier or diluents liquid, e.g. water, may be mixed with such ingredient to form the beverage. Typically, a predetermined amount of beverage is formed and dispensed on user-request, which corresponds to a portion (e.g. a serving). The volume of such portion may be in the range of 25 to 200 ml and even up to 300 or 400 ml, e.g. the volume for filling a cup, depending on the type of beverage. Formed and dispensed beverages may be selected from ristrettos, espressos, lungos, cappuccinos, latte macchiato, caf latte, americano coffees, teas, etc... In particular, a coffee machine may be configured for dispensing espressos, e.g. an adjustable volume of 20 to 60 ml per portion, and/or for dispensing lungos, e.g. a volume in the range of 70 to 150 ml per portion.

[0009] The machine has a body including a fluid line extending from a liquid inlet to a beverage outlet.

[0010] The beverage outlet is typically located above a placement location for a beverage recipient, e.g. a cup or a mug.

[0011] The placement location can be associated with a machine recipient support for supporting such user-recipient under the outlet. The support can be: associated with a drip tray e.g. a drip tray supporting the support; and/or movable relative to the housing vertically under the outlet and/or away from under the outlet for enabling a placement of user-recipients of different heights under the outlet. Examples of suitable recipient supports are disclosed in EP 0 549 887, EP 1 440 639, EP 1 731 065, EP 1 867 260, U.S. Pat. No. 5,161,455, U.S. Pat. No. 5,353,692, WO 2009/074557, WO 2009/074559, WO 2009/135869, WO 2011/154492, WO 2012/007313, WO 2013/186339, EP 2014198712, EP 2014198710 and EP 2014198715.

[0012] The machine is provided with a liquid tank that has an outlet connected to the liquid inlet. The machine has a carrier assembled to the body for carrying the liquid tank.

[0013] The fluid line may include at least one of: a liquid sensor, e.g. a flowmeter and/or a pressure sensor and/or a temperature sensor; a pump for driving a liquid from a or said source to the outlet, e.g. a solenoid pump (reciprocating piston pump) or a peristaltic pump or a diaphragm pump; and a thermal fluid conditioner such as a heater and/or a cooler.

[0014] The thermal conditioner may be a boiler or a thermoblock or an on demand heater (ODH), for instance an ODH type disclosed in EP 1 253 844, EP 1 380 243 and EP 1 809 151.

[0015] Examples of pumps and their incorporation into beverage machines are disclosed in WO 2009/150030, WO 2010/108700, WO 2011/107574 and WO 2013/098173.
