Definitions

  • the present invention relates to an arrangement for mixing beverages, in particular from a liquid base substance, in particular from carbonated water, and a beverage concentrate.
  • a beverage concentrate or optionally one of several beverage concentrates can be mixed with carbonated water to form a soft drink immediately before consumption.
  • the carbonated water required for this purpose is cooled and stored under pressure. In a known manner, this carbonized water is output for the mixing process via a shut-off valve and, if appropriate, via an expansion valve downstream of this.
  • the quality of the mixed drink depends to a large extent on the mixing ratio of beverage concentrate and carbonated water. For this reason, it is essential to take measures that are suitable to ensure the required mixing ratio under the different conditions that are normal in normal operation. For example, it is known to determine the amount of beverage concentrate in portions via metering chambers.
  • the object of the present invention is now to provide an arrangement by which an exact determination of the dispensing quantities of liquids is made possible.
  • An arrangement which meets these requirements is characterized in accordance with the invention in that a flow control valve controlling a constant flow irrespective of the pressure of the supplied liquid is directly connected to an outlet shut-off valve and that a timing device is assigned to the outlet shut-off valve.
  • An arrangement constructed according to these features of the invention follows the concept of assigning different functional requirements to different functional units and arranging them as closely as possible to one another.
  • a functional requirement is given in that the opening time of the dispensing valve, which is predetermined by the time control, is realized as precisely as possible. For this reason, an outlet shut-off valve is arranged, which can do this task to an outstanding degree.
  • this unit is not responsible for the flow rate control.
  • the flow control valve controlling a constant flow is arranged independently of the pressure of the supplied liquid. This, in turn, can do an excellent job.
  • both functional units are arranged in the immediate vicinity, since this largely prevents an uncontrolled outflow of the liquid during the switching phases of the outlet shut-off valve.
  • the arrangement according to the invention is characterized in that the pressure-independent flow control valve has a piston chamber with a displaceable piston loaded with restoring force, which divides the piston chamber into two sections, that a flow restrictor section lies between these two sections and that the first chamber -Part area in which the restoring force acts, an unchanged Liche flow inlet opening and the second piston comb portion has a flow outlet throttle which is variable in cross section due to the piston position.
  • a particularly uniform flow rate is achieved by such an arrangement, since the measures taken are extremely sensitive, in particular able to react to pressure fluctuations and to change the throttle behavior as a function thereof.
  • the flow inlet opening into the pressure-dependent flow control valve is designed as a throttle section.
  • a pressure reduction is already carried out in this area, so that the control behavior is closer to an area approaching the output pressure.
  • the arrangement according to the invention is characterized in that a plurality of bores are arranged on the circumference of the throttle chamber in the displacement area of the piston.
  • a particularly favorable control characteristic for the flow rate can be achieved by slightly displacing these bores in the piston stroke direction.
  • a spring will expediently be arranged to provide the restoring force on the piston. To readjust the flow rate to a certain desired quantity and to readjust the arrangement, it is expedient to ensure that the restoring force can be adjusted. A pressure screw acting on the return spring can be used for this.
  • the arrangement according to the invention is preferably further developed such that the restoring force for the control piston is guided via a temperature compensation rod.
  • plastic can be used, for example, for the control valve housing, while the control piston consists of metal.
  • This choice of material is advantageous both in terms of production technology and sliding technology.
  • a particularly simple arrangement of the temperature compensation rod is obtained if it is integrated in the adjusting screw mechanism.
  • a vending machine for selectively mixing of different beverage concentrates with chilled CO z -water to a mixed drink contains as essential ingredients a mixing trough 1, in which the mixing process is initiated or carried out beverage concentrate container 2, from which via metering 3 portions, the beverage concentrates of the mixing channel 1 are supplied and a storage container 4 for cooled CO 2 water, which can flow into the mixing trough as required via a discharge valve 5.
  • the beverage mix leaves the mixing trough 1 via an outlet funnel 6.
  • the CO 2 water supply is cooled by refrigerants which are passed through a pipe 7 wound around the storage container 4.
  • the CO, water supply within the container 4 is supplemented by the quantities withdrawn via the discharge valve 5 in that fresh water is supplied via a pipeline 8, controlled by a valve system 9, and via a pipeline 10 from a container 11 with CO, gas filling - Controlled by a valve system 12 - CO, gas is supplied.
  • the quality of the mixed drink that can be achieved depends to a large extent on the mixing ratio of beverage concentrate and carbonated water.
  • the beverage concentrate quantity determination is by be known configurations of the metering devices 3 can be carried out with sufficient accuracy.
  • a corresponding amount of carbonated water is now to be mixed into the respective beverage concentrate amounts.
  • the output valve 5, which is shown in section in FIG. 2, serves to control the output of this carbonized water from the storage container 4.
  • the time control takes place via a control circuit 13, which is not to be explained in detail.
  • the output valve 5 basically consists of two functional units, namely an electromagnetically controllable flow / shut-off valve 14 and a flow control valve 15 which controls the flow rate independently of the supplied liquid pressure.
  • the flow / shut-off valve 14 contains an electromagnetic coil 16. When excited a magnetic armature 17 is attracted against the force of a spring 18 by current flow. In this case, a membrane 19 connected to this plunger anchor 17 lifts off its valve seat 20, so that the carbonized water supplied from the reservoir 4 via the line 21 can pass this shut-off valve essentially unhindered. Through channels 22 and a housing bore 23, this reaches the area of the flow control valve 15, specifically in the inlet-side portion 24 of a piston chamber of this flow control valve.
  • a piston 25 arranged in this piston chamber is acted upon by the force of a spring 26, specifically in the direction of the inflow region 24 of the carbonized water.
  • a throttle bore 27 is made in the end face of the piston, so that the carbonized water supplied can reach the second partial region 28 of the first partial region 24 of the piston chamber. When there is flow, a pressure reduction takes place at this throttle bore 27.
  • a plurality of bores 29 are arranged in the cylinder liner 30 on the circumference of the second partial region 28 of the piston chamber and lead to an outflow channel 31 via a ring line 35 in the housing wall. These bores 29 lie in the stroke area of the piston skirt 25.
  • the piston is pressed to an increased extent against the force of the spring 26, so that the outlet openings 29 are covered more by the piston skirt.
  • An increased throttling effect occurs at these points. If there is less pressure in the area of the first partial area 24 of the throttle chamber, the following accordingly takes place the piston 25 of the force of the spring 26 and the outlet openings 29 are ver - strengthens released. The throttling effect on the liquid flowing through in this area decreases accordingly.
  • Appropriate dimensioning means that the throttling effect in the area of the outlet openings 29 changes in proportion to the liquid pressure occurring in the first partial area 24 of the piston chamber. However, this means that the flow rate of the carbonated water can be regulated constantly irrespective of the liquid pressure supplied via line 21.
  • the amount of carbonated water dispensed can be determined extremely precisely by appropriate time control.
  • the force of the spring 26 can be varied by changing its pretension via an adjusting screw 32.
  • a temperature expansion is - compensating rod 33 integrated, on which a sleeve is placed 34th
  • the return spring 26 is supported against this sleeve 34, that is to say indirectly with respect to the valve housing.
