Definitions

  • the present invention relates to a device for dispensing alimentary liquids.
  • alimentary liquids as used herein means hot or cold, aerated or non-aerated water and drinks in general, such as tea or coffee.
  • DE-A-19833832 discloses an apparatus having the features of the device according to the preamble of appended claim 1.
  • the main object of the present invention is to provide a device which is integrated into a sink unit and which avoids the phenomenon of sudden change in flow rate when still water is withdrawn.
  • the letter A indicates schematically a sink unit (shown in plan view) into which the device of the invention, described hereinafter, is integrated.
  • the water entering the device passes through a filter B, for example of activated carbon type, and fills a cold water container C.
  • the water is kept constantly refrigerated by a stainless steel coil acting as an evaporator and pertaining to a refrigeration circuit provided with a compressor.
  • a level sensor positioned in the container C, activates (opens) a solenoid valve 1 each time the level falls below a given threshold.
  • the water is withdrawn from the container C by a pump D.
  • the delivery side of this pump is connected via a solenoid valve 2 to a dispenser E positioned on the sink unit.
  • the delivery side of the pump D is connected via a solenoid valve 3 to an aerator F (while the valve 2 remains closed).
  • the aerator F the water is aerated with CO 2 originating from a pressure reducer H.
  • the connection between the cylinder G and the aerator F comprises a second pressure reducer L and, in parallel therewith, a solenoid valve 5. If only slightly sparkling water is required, this solenoid valve is closed and the CO 2 passes through the pressure reducer L; if instead highly sparkling water is required the solenoid valve 5 is opened.
  • the aerated water reaches the dispenser E via a solenoid valve 4.
  • the pump D can be connected either to that circuit branch in which the aerator F is disposed, to supply aerated water to the dispenser E, or to that circuit branch which via the valve 2 supplies still water, i.e. non-aerated, to the said dispenser E. In this manner each time still or sparkling water is dispensed, a constant flow is always obtained whichever water is delivered.
  • An indicator showing the filter life and an indicator indicating when the cylinder is empty are provided on a control panel, not shown, which at least partly controls the intervention of the solenoid valves.
  • the aerated water can be mixed with syrups and the like obtained from containers, not shown, connected to the line M. Mixing with still water is also possible by providing the valve K in the same line as the valve 2.
  • the control panel can also enable the temperature and the type of water and/or the preferred drink to be selected.
  • a solenoid valve 6 downstream of the filter B and downstream of the solenoid valve 1 there is provided a solenoid valve 6 for the feed of tap water to a container P in which it is heated before arriving at a dispenser S.
  • the water can be heated by temperature-controlled electrical resistance elements or by utilizing the heat originating from the condenser forming part of the refrigeration circuit the evaporator of which is used for cooling the water in the container C.
  • the condenser is inserted into the container P and can be represented by a spiral tube.
  • the scheme of Figure 2 differs from that of Figure 1 in that in addition to the cold water container, here indicated by C 1 , there are provided other containers, for example for coffee, tea and the like, indicated by C 2 and C 3 . Each of these containers has its own exit solenoid valve 7a, 7b, 7c for selection of the desired drink. As the two schemes derive from the same origin, the common parts are indicated in them by the same references.
  • a possible embodiment of the dispenser E is shown schematically in Figure 3 , in which it can be seen that at the base of the dispenser there are provided selection buttons E 1 , E 2 . E 3 , by which still water, slightly sparkling water or very sparkling water can be respectively obtained by operating the relative solenoid valves, as can be deduced from the aforegoing.
  • the components shown in the schemes are integrated into the sink unit A.
  • FIG 4 shows a further possible embodiment of the dispenser E for alimentary liquids (still water, aerated water, various drinks etc.)
  • the dispenser E is integrated into a mixer K of traditional type for cold/hot mains water, the pipes of which are completely independent of the drink dispensing pipes indicated in the figure by the reference numeral 10.
  • the dispenser E of Figure 4 comprises a tubular support 12 housing an electrical switch 14 which, by means of a relative pushbutton 14a, enables both the type of drink and the drink delivery to be selected.
  • the body of the dispenser is provided with an indicator (not shown), for example an LED or liquid crystal display, which informs the user of the type of drink selected and/or its temperature.
