Definitions

  • This invention relates to a device for dispensing liquids, such as beverages .
  • Dispensing devices can be used for dispensing beverages of many different kinds, especially in pubs or restaurants.
  • Patent EP1289874 describes a device comprising a guide tube that defines an outside channel and an inside channel.
  • the inside channel also accommodates the beverage dispensing tube and, adjacent to the dispensing tap, communicates with the outside channel. This creates a path for the cooling medium along the intercommunicating inside and outside channels so that the beverage is cooled until it is near the dispensing station.
  • a beverage container is placed in a storage compartment cooled by the same medium that cools the beverage in the dispensing column, this storage compartment communicating directly with the inside and outside channels .
  • Dispensing devices of this kind are not free of disadvantages.
  • cooling medium is preferably air
  • heat exchange efficiency is considerably reduced.
  • Use of other fluids with very low melting points as the cooling medium would, however, create a different problem, since such fluids reach very low temperatures and are in direct contact with the beverage, creating a risk of the beverage freezing in the part of the dispensing tube that is inside the column. This problem occurs especially if an extended length of time elapses between one dispensing and next.
  • the present invention therefore has for an aim to overcome the above mentioned disadvantages by providing a dispensing device with optimised control of the cooling means, thus saving energy and reducing costs.
  • Another aim of the invention is to provide a dispensing device that permits cool beverage to be dispensed irrespective of the length of time the beverage remains in the part of the dispensing line outside the insulated compartment in which the beverage container is stored.
  • Figures 1 and 2 are schematic side views, with some parts in cross section and others cut away, of the liquid dispensing device according to the invention.
  • Figures 3, 4a, 4b, 4c are perspective views of parts of the liquid dispensing device according to the invention.
  • Figures 5, 6a, 7 and 8 are side views of a part of the liquid dispensing device in a particular open configuration.
  • Figure 6b is a cross section of the part of the device illustrated in Figure 6a in a closed configuration.
  • the numeral 1 denotes a beverage dispensing device of the type comprising a cooled storage compartment 2 and a beverage dispensing line 4.
  • the compartment 2 is cooled at least by a first cooling medium and houses at least one beverage container 3.
  • the dispensing line 4 extends from the beverage container 3 to a tap 5 located on a dispensing head 6.
  • the device 1 characteristically comprises at least one first cooling circuit 11 that uses first movement means 12 to circulate the first cooling medium using, and one second cooling circuit 21 that uses second movement means 22 to circulate a second cooling medium that is in thermal contact with the beverage dispensing line 4.
  • the first and second cooling mediums are fluid dynamically isolated from each other and the two cooling circuits 11, 21 exchange heat with a single cooling element 7 that cools both mediums.
  • the single cooling element advantageously comprises an evaporator 71 and/or may have external cooling fins 73 to facilitate heat exchange with the first cooling medium.
  • the evaporator 71 forms part of a cooling system with which the device 1 is equipped.
  • the first cooling circuit 11 enables the cooling medium to circulate between the single cooling element 7 and the beverage container 3, whilst the second cooling circuit 21 enables the cooling medium to circulate between the single cooling element 7 and the dispensing head 6.
  • the first means 12 for moving the first cooling medium preferably comprise a fan 120 driven by an electric motor in such a way as to produce forced circulation of the first cooling medium to facilitate heat exchange.
  • the first cooling circuit 11 also includes means 14 for guiding and channelling the first cooling medium for the compartment 2.
  • These comprise a wall 26 that divides the compartment 2 into a first zone 24 where the evaporator 71 is located and a second zone 25 where the beverage container 3 to be cooled is located.
  • the wall 26 has openings made in it, preferably but not necessarily both at the top and bottom of it.
  • the fan 120 creates a unidirectional flow between the two zones 24 and 25.
  • the second means 22 for moving the second cooling medium may comprise a submersible pump 23 located inside a coil 72 of the evaporator 71 (see Figure 1) .
  • the second means 22 for moving the second cooling medium comprise a pump 231 located outside and, in particular, downstream of the single cooling element 7 (which might be the evaporator 71) .
  • the size and capacity of the pump are independent of the evaporator 71.
  • the cooled compartment 2 is inside a unit 13 that is insulated to minimise heat loss and thus reduce power consumption.
  • the dispensing head 6, on the other hand, is located outside the insulated unit 13.
  • the dispensing head 6 comprises a cooling chamber 8 in fluid communication with an inlet duct 9 and with a delivery duct 10 for the second cooling medium, the inlet duct 9 and the delivery duct 10 for the second cooling medium letting the second cooling medium into the chamber 8 and delivering it from the chamber 8.
  • the delivery duct 10 extends into the cooling chamber 8 and reaches the top 81 of the chamber.
  • the second cooling medium flows into the initially empty cooling chamber 8, it forces all the air out.
  • the air flows out through the delivery duct 10 and does not remain trapped in the dispensing head 6. This is because the second cooling medium starts “flooding" the dispensing head 6 from the bottom and rises gradually towards the top of it.
  • the dispensing head 6 comprises a column 61 and the cooling chamber 8 is made inside the column 61, in thermal contact with the beverage dispensing line 4. This guarantees that the beverage in the parts of the dispensing line 4 outside the cooled, insulated compartment 2 are also cooled.
  • the dispensing head 6 comprises an internal housing 610 for accommodating the dispensing line 4, the dispensing line 4 being in thermal contact with the cooling chamber 8.
  • the dispensing head 6 comprises a mobile part 600 to facilitate fitting and removal of the beverage dispensing line 4 to and from the housing 610.
  • the dispensing head 6 comprises a door 611 providing access to the housing 610.
  • the door 611 may coincide with the mobile part 600.
  • the mobile part 600 facilitates maintenance, cleaning and substitution of the dispensing line 4 in order to guarantee the maximum level of hygiene for the dispensing line 4 itself.
  • the mobile part 600 can be connected to the rest of the dispensing head 6 by fastening means 66: in Figures 7 and 8, for example, the fastening means 66 comprise a hinge 661; in Figures 5 and 6a, on the other hand, the mobile part 600 is completely removable from the dispensing head 6 and the fastening means 66 comprise a protrusion 662 that can be inserted into a matching hole or socket. In both cases, the fastening means 66 comprise means 664 for latching and unlatching the door 611 to and from the rest of the dispensing head 6.
  • the dispensing head 6 optionally but preferably also comprises a protrusion 612 extending into the housing 610.
  • the protrusion 612 at least partly defines a hole 613 through which the beverage dispensing line 4 can pass.
  • the protrusion 612 advantageously constitutes means for positioning the beverage dispensing line 4 against the cooling chamber 8. This improves heat exchange between the second cooling medium in the cooling chamber 8 and the beverage flowing in the dispensing line 4. It also improves heat exchange between the second cooling medium and the beverage which, between one dispensing and the next, remains in the part of the dispensing line 4 at the head 6.
  • the protrusion 612 is advantageously attached to the door
  • the cooling chamber 8 is mounted in a fixed position.
  • the cooling chamber 8 may be attached to a dispensing counter.
  • Figures 4a, 4b and 4c illustrate other non-restricting embodiments in which the dispensing head 6 comprises a column 61 and the cooling chamber 8 is made outside the column 61, but again in thermal contact with the beverage dispensing line 4. Thermal contact is guaranteed by the use of metal or other good thermally conductive materials between the cooling chamber 8 (which is positioned against the column 61) and the beverage dispensing line 4.
  • the column 61 comprises a channel 41 for guiding the beverage dispensing line 4.
  • the channel 41 extends from a base 63 of the column 61 to the dispensing tap 5 and defines an internal space 42 that houses the beverage dispensing line 4 and is fluid dynamically isolated from the cooling chamber 8.
  • the first and second cooling mediums may be of the same type, they are, advantageously, two different types of fluid.
  • the two circuits 11, 21 are separate, the two fluids may have a different flow rate, specific heat and temperature.
  • the flow rates of the two circuits 11, 21 may be regulated independently of each other by the two movement means
  • the first cooling medium is air, whose cost is practically zero, whilst the second cooling medium may be any fluid with a suitable melting point such as, for example, glycol.
  • Air is also used as an operating fluid since an air compressor 15 is used to fill an inflatable jacket which, as it expands, forces the beverage out of the container 3.
  • the inflatable jacket may be either inside or outside the element that actually contains the beverage .
  • the invention achieves important advantages . First of all, it is constructionally simple and limits the number of cooling parts required.
  • the cooling medium does not come into direct contact with the beverage dispensing pipe. This makes it possible to use a cooling medium with a melting point below 0 0 C and minimises the risk of freezing the beverage on the walls of the dispensing line, while at the same enhancing the chilling efficiency of the cooling mediums and enabling low temperatures to be reached. The risk of the beverage freezing along the inside walls of the beverage pipe is greatly reduced. It will be understood that the invention can be adapted and modified in several ways without thereby departing from the spirit of the invention.
