Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a device for dispensing liquids, an assembly comprising a control system and such a device and a method for dispensing a liquid. It applies to the distribution of drinks. For example for the distribution of soda, beer, cider, wine, tea, juice.

Devices are arranged individually or in the park, sold or rented for a period which can vary from one day to one year, or made available.

The places of use are bars, restaurants, boats, association premises, holiday or sports clubs, festivals, campsites, bowling alleys, casinos, etc. They are particularly suitable for remote and difficult to access places.

STATE OF THE ART

There are known storage and distribution facilities for liquids under pressure of carbon dioxide (CO ₂ ).

These installations take up considerable space and weight. These systems cannot be installed outside bars because their installation requires no special technical knowledge for the maintenance and upkeep of the drums.

The document FR2772738 offers a storage and distribution facility for carbonated drinks.

However, this type of installation is not optimized with regard to its carbon footprint. The type of barrel used is bulky and metallic. The material of the barrel does not optimize the carbon footprint of such an installation. Metal drums generate maintenance costs and a significant maintenance time in management, such as cleaning with water and being stored. In fact, the constraint of recovering returnable drums (therefore transport) and the constraint of cleaning are at the origin of the poor carbon footprint.

The term "carbon footprint" designates an accounting tool greenhouse gas emissions, which must take into account the primary energy and the final energy of products and services.

Another drawback of this type of installation is that it is limited in terms of the diversity of the offer because this device is limited to a single type of drink. The document WO2011 / 107146 A1 discloses a device for dispensing drinks; the document EP0389191 A1 discloses a barrel comprising a PET shell with a flexible pouch and a means for blowing a gas; the document WO2011 / 000021 A1 discloses a flow meter for a draft circuit; the document GB2349198 A discloses a foam blocking means.

OBJECT OF THE INVENTION

The present invention aims to remedy these drawbacks.

To this end, according to a first aspect, the present invention relates to a device according to claim 1.

Each barrel is made up of a PET shell (acronym for ethylene polyterephthalate) inside which is positioned a pocket made of flexible material containing the liquid. According to one embodiment, each barrel is cylindrical in shape and has a handle made of PET. Preferably, each barrel is made of recyclable material. The barrel is disposable and recyclable. The use of these barrels implies a better carbon footprint and does not require transport for recovery and cleaning. There is no deposit on the barrel. The use of three barrels allows for choice and without taking up too much space. In addition, the absence of contact between the air blown into the barrel, between the shell and the flexible pouch, and the liquid ensures a longer shelf life than with a gas pressure draft system in a metal barrel, the order of 3 weeks on the beer according to the technical characteristics provided against 3 to 4 days.

Thanks to this device, the carbonated drink is maintained at the desired temperature while retaining the taste of the drink.

In addition, the draft circuit cooling system cools the solenoid valves and prevents the creation of foam when there is no draft for some time, the entire draft line being cooled down to the tap.

Thus the device is autonomous, because it can be installed anywhere and does not require any particular skill. The barrel change is simple to carry out.

The database is located on a server with a host. With each action of a client, the management system interrogates the database and updates it if necessary by the connection means.

The database management system makes it possible to be associated with one or more tables, which makes it possible to manage several places at the same time.

The casters allow the device to be moved. The device just requires an electrical outlet to be powered. In an exemplary embodiment, the device comprises a battery.

In embodiments, the device includes a plurality of drums and liquid dispensing valves.

Thus the device offers the possibility of having several types of liquid.

In embodiments, the connection means is wired or wireless.

The connection means is real time and wireless. For example using Wi-Fi (registered trademark means a set of wireless communication protocols governed by the standards of the group IEEE 802.11, ISO / IEC 8802-11) or a telecommunications network.

Real-time is defined by the fact that information is transmitted or collected to the microcontroller without waiting for the end of exchanges information. For example, there is an exchange of information with the microcontroller during the liquid dispensing period.

A wired connection can be substituted for the wireless connection.

Each barrel is thermally insulated from the other barrels by a partition wall.

Thus the device integrates different types of liquid to store and distribute them at different temperatures. Each keg has its own temperature.

DESCRIPTION OF EXAMPLES OF EMBODIMENT OF THE INVENTION

Figure 1 , according to one embodiment, shows a device for dispensing drinks. The device is in the form of a table. The device includes a power supply, not shown.

The device comprises a body 10 in which are arranged three barrels 11. Each barrel 11 comprises a liquid to be dispensed. The device includes also a cooling system 12 of a draft circuit 24 disposed between a barrel 11 and a dispensing tap 15.

The three distribution valves are located substantially in the center of the tray.

The device comprises a pressure drawing system 13 adapted to draw the liquid from the barrels 11.

• un moyen d'insufflation d'un gaz à l'intérieur du fût 11,
• une électrovanne 25 positionnée dans le circuit de tirage 24 et régulant la sortie du liquide,
• un débitmètre positionné dans le circuit de tirage 24.

The pressure drawing system 13 comprises for each drum 11:

• a means for blowing a gas inside the barrel 11,
• a solenoid valve 25 positioned in the drawing circuit 24 and regulating the outlet of the liquid,
• a flow meter positioned in the draft circuit 24.

The flow meter is connected to the management system 14 to inform the management system 14 of the liquid flow. The flow information is used to know the volume remaining in the barrel 11 and is used by the user to have a statement of the balance he has left.

The flow meter of each draft circuit gives the flow information to the electronic card which will control the solenoid valves according to the associated instructions.

The solenoid valve 25 operates with the management system 14 which authorizes the flow of beverage as a function of the state of the customer account.

The information on the customer balance authorizes the customer to use himself according to a limited volume of liquid.

The barrels 11 have a PET shell and a flexible aluminum wall which contains the liquid.

According to an exemplary embodiment, the means for blowing a gas inside the barrel blows the gas between the PET shell and the aluminum bag of the barrel. Thus the compressed liquid leaves through the drawing circuit.

According to one embodiment, an air compressor is located in the body of the device and blows air inside the barrel.

According to one embodiment, the insufflation means is a bottle of compressed gas.

In the example of the figure 1 , a compressor 21 compresses air and sends this compressed air inside the barrel 11 between its shell and the flexible wall in aluminium. The air compresses the flexible wall and forces the liquid which leaves through the draft circuit 24.
