Definitions

  • the invention pertains to drinking water dispensers for dispensing non- carbonated and carbonated chilled drinking water.
  • Drinking water dispensers for dispensing non-carbonated and carbonated chilled drinking water include a non-carbonated drinking water dispensing circuit having a drinking water reservoir and a thermostat controlled refrigeration circuit with an evaporation coil coiled around the drinking water reservoir for selectively dispensing non-carbonated water chilled to a temperature of between 4 0 C and 9°C.
  • Such drinking water dispensers also include a carbonated drinking water dispensing circuit having a carbonator in flow communication with their drinking water reservoir for selectively dispensing carbonated drinking water also chilled to a temperature of between 4 0 C and 9 0 C for proper retention of carbonation in poured carbonated drinking water. Failure to dispense carbonated drinking water suitably chilled will cause partial or total loss of carbonation.
  • Such drinking water dispensers commercially available from Cosmetal isti Di Refrigeraz Ltd, Italy (www.cosmetal.com) include an evaporator coil • coiled around their drinking water reservoir for cooling its non-carbonated drinking water contents, and their carbonator for cooling its carbonated drinking water contents.
  • this approach is problematic due to the fact that their drinking water reservoirs and carbonators typically differ in temperature by a few degrees Celsius such that in the case their refrigeration circuit is controlled by sensing the temperature of their drinking water reservoir, consumption of non- carbonated drinking water can lead to their carbonator freezing over with possible permanent damage.
  • their refrigeration circuit is controlled by sensing the temperature of their carbonator, non-carbonated drinking water may not be sufficiently chilled.
  • US Patent No. 4,597,509 to Pereira illustrates and describes a drinking water dispenser with a transfer line immersed, in a refrigerated drinking water reservoir for cooling carbonated drinking water immediately prior to its dispensing, however, this requires apertures to be formed in a drinking water reservoir leading to sealing problems, and the like.
  • US Patent No. 4,764,315 to Brusa illustrates and describes a drinking water dispenser in which a carbonator itself is immersed in a refrigerated drinking water reservoir, however, this impedes access to the drinking water reservoir for cleaning purposes, maintenance purposes, and the like.
  • the present invention is for drinking water dispensers including a non- carbonated drinking water dispensing circuit having a drinking water reservoir and a thermostat controlled refrigeration circuit with an evaporator coil coiled around the drinking water dispenser for selectively dispensing chilled non- carbonated drinking water, and a carbonated drinking water dispensing circuit with a carbonator in flow communication with the drinking water reservoir for selectively dispensing chilled carbonated drinking water.
  • the carbonator is cooled by heat conduction with the drinking water reservoir's exterior surface for substantially equalizing the former's temperature with the latter' s surface temperature thereby precluding the aforesaid problems arising in the case of a few degrees Celsius temperature difference therebetween, and additionally affording convenient access to both the drinking water reservoir and the carbonator.
  • the present invention preferably employs drinking water reservoirs and carbonators designed for side by side intimate contact for direct heat conduction.
  • the drinking water reservoirs and the carbonators can have flat or curved contact surfaces.
  • the present invention can be readily implemented with existing drinking water reservoirs and carbonators which both typically have circular transverse cross-sections by way of a heat exchange interposer disposed therebetween with oppositely directed concave shaped cylindrical contact surfaces for ensuring sufficient contact area.
  • Existing drinking water dispensers for dispensing chilled non-carbonated drinking water can be retrofitted using a conversion kit to convert them to drinking water dispensers for dispensing chilled carbonated and non-carbonated drinking water in accordance with the present invention.
  • the present invention is particularly suitable for low volume drinking water dispensers of both the point of use type connected to water mains and the bottle type for the so-called Home Office Delivery market, but can also be implemented for high volume point of use drinking water dispensers.
  • Fig. 1 is a partially cut away pictorial representation of a drinking water dispenser with a first preferred cooling arrangement of a carbonator in accordance with the present invention
  • Fig. 2 is a schematic diagram of the drinking water dispenser of Figure 1;
  • Fig. 3 is a close-up view of the carbonator cooling arrangement of the drinking water dispenser of Figure 1;
  • Fig. 4 is a close-up of a second preferred carbonator cooling arrangement in accordance with the present invention.
  • Fig. 5 is a close-up of a third preferred carbonator cooling arrangement in accordance with the present invention.
  • FIG. 1 shows a drinking water dispenser 1 including an upright cabinet 2 for supporting an inverted water bottle 3 for feeding a non-carbonated drinking water dispensing circuit 4 including a drinking water reservoir 6 having a circular transverse cross section with a convex shaped cylindrical exterior surface 7 and retaining non-carbonated drinking water.
  • the drinking water reservoir 6 is preferably made of stainless steel but alternatively can be made out of plastic material.
  • the drinking water reservoir 6 is preferably removable from the cabinet 2 for cleaning and maintenance purposes but 1 alternatively may be a permanent fixture.
  • the drinking water reservoir 6 is in flow communication with a manually operated cold water faucet 8 for selectively dispensing chilled non- carbonated drinking water, and a hot water tank 9 having a manually operated hot water faucet 11 for selectively dispensing hot drinking water.
  • the drinking water dispenser 1 includes a conventional thermostat controlled refrigeration circuit 12 having a compressor 13, a condenser 14, an expansion valve 16, and an evaporator coil 17 for cooling the drinking water reservoir 6 to about 4 0 C (see Figure 2). . . ., .
  • the drinking water dispenser 1 includes a carbonated drinking water dispensing circuit 18 having a water pump 19 connected to the drinking water reservoir 6, a regulated CO 2 cylinder 21, and a carbonator 22 connected to the water pump 19 and the CO 2 cylinder 21 and in flow communication with a manually operated soda faucet 23 for selectively dispensing chilled carbonated drinking water.
  • Suitable carbonators include inter alia the DES Ultra Carb 1000 carbonator commercially available from ⁇ Cornelius, Inc., USA (www.cornelius.com).
  • Suitable water pumps, are available from Shurflo, LLC, USA (www.shurflo.com).
  • the carbonator 22 has a concave shaped cylindrical exterior surface 24 for intimately contacting the drinking water reservoir's exterior surface 7 for cooling its carbonated drinking water contents by heat conduction to about the same temperature as the chilled non-carbonated drinking water.
  • the exterior surface 24 has a peripheral channel 26 for receiving the evaporator coil 17, and may or may not touch the evaporator coil 17.

  • a pump protection device 29 senses the level of non-carbonated drinking water in the drinking water reservoir 6 for precluding operation of the water pump 19 on the condition that the level drops below a predetermined height.
  • Figure 4 shows a drinking water reservoir 6 and a carbonator 22 having square transverse cross sections and flat exterior surfaces 31 and 32, respectively.
  • the exterior surface 32 is formed with a channel 33 similar to the channel 26.
  • the exterior surface 31 and the exterior surface 32 are in direct contact for cooling the carbonator 's carbonated drinking water contents by heat conduction to about the same temperature as the drinking water reservoir's non-carbonated drinking water.
  • Figure 5 shows a drinking water reservoir 6 with the convex shaped cylindrical exterior surface 7 and a carbonator 22 with a convex shaped cylindrical exterior surface 34, and a heat exchange interposer 36 having a pair of opposite concave shaped cylindrical exterior surfaces 37 and 38 interposed between the drinking water reservoir 6 and the carbonator 22 for efficiently conducting heat from the latter to the former for cooling the carbonator 's contents.
