DETAILED DESCRIPTION OF THE DRAWINGS

[0044] The following detailed description relates to a preferred embodiment of the invention illustrated in the drawings, and it should be appreciated that it is not to be regarded as limiting.

[0045] FIG. 1 illustrates a front view of an internal refrigeration system 10 for cooling and dispensing packaged beverages, such as canned beverages 101 and bottled beverages (not shown). The refrigeration system 10 has a housing 100, a plurality of gravity fed dispensers 200 and a water delivery system 300. The gravity fed dispensers 200 and the water delivery system 300 are housed within the housing 100.

[0046] The housing 100 is a substantially rectangular insulated body constructed from metal, such as aluminium, for example or plastic, for storage and dispensing canned beverages 101 through a dispensing outlet 110. The dispensing outlet 110 is located on a side of the housing 100 and allows customers and servers to easily access the canned beverages for dispensing. The housing 100 can be insulated by a fibreglass layer (not shown) between the interior and exterior of the housing 100.

[0047] The housing 100 also includes a loading opening 120 to allow a user to load canned beverages 101 into the refrigeration system 10.

[0048] As shown, the housing 100 contains a plurality of gravity fed dispensers 200 for storing and providing canned beverages 101 to dispensing outlet 110. The gravity fed dispenser 200 includes a loading end 210 and a dispensing end 220. Extending between the loading end 210 and the dispensing end 220 is a winding travel path defined by a series of inclined racks 230 defining multiple levels in a zig-zag formation.

[0049] The racks 230 extend horizontally from one side of the housing 100 to the opposing side in a winding path beginning at the loading end 210 and finishing at the dispensing end 220 of the dispenser 200.

[0050] The racks 230 each have a minimum incline to the horizontal such that a canned beverage 101 moves along the rack 230 toward the dispensing end 220 in response to a gravitational force. As shown in FIG. 1, the angle of the racks 230 can be a substantially small angle. However, the inclination of the racks 230 can be anywhere between 1-45.

[0051] The racks 230 of the dispenser 200 include opposing side walls 240 separated by an aperture which improves air circulation around the canned beverages 101. The opposing side walls 240 guide and prevent canned beverages 101 from falling off the rack 230.

[0052] While the dispenser 200 is described as gravity fed, it will be appreciated that the dispenser 200 can include a mechanical conveyor for conveying beverages along the racks 230.

[0053] The water delivery system 300 is defined by a sprinkler type system that is mounted along the top of the housing 100. The water delivery system 300 is provided with a cooled fluid, such as water, from a cooling or refrigerating unit (shown in FIG. 6) which typically cools the fluid to around 1 C. (but could cool the fluid to anywhere between 0 C. to 10 C.) and can assist in cooling the interior of the housing 100. The refrigerating unit can be a typical unit found in refrigerators comprising a compressor, condenser coils and evaporator coils. However, it will be appreciated by a person skilled in the art that other methods and devices for cooling can be used.

[0054] While not shown, the refrigerating unit may include a water inlet to receive water and a water outlet to drain the water from the refrigerating unit after use. The refrigerating unit may alternatively be a closed loop system.

[0055] As shown, the system 300 includes a plurality of pipes 310 and outlets 320 for delivering the water. The pipes 310 illustrated in FIG. 1 run parallel to the racks 230. However, the pipes 310 can also run transverse to the racks 230.

[0056] Located at an end of the housing 100 is a large opening 330 for delivering larger amounts of cooled water at a higher rate. As shown, the system 300 includes a control mechanism in the form of a rotatable mechanism 340 for controlling the flow of the cooled water.

[0057] Additionally, the pipes 310 can run along the interior walls of the housing 100 to provide greater water saturation and coverage, and to increase the cooling effect.

[0058] Further additional pipes 350 and outlets 360 may also extend between the racks 230 to provide better saturation and faster cooling of the canned beverages 101 located towards the dispensing end 220.

[0059] During operation, the housing is sealed and cooled water is delivered to the pipes 310 of the sprinkler system 300 and dispersed in a spray or mist to cover the canned beverages 101 in the cooled water. As more cooled water is dispersed, the cooled water trickles down from the canned beverages 101 at the top of the housing 100 to the canned beverages 101 at the bottom of the housing 100.

[0060] Once the cooled water reaches the floor of the housing 100 it is then recycled, re-cooled and dispersed through the pipes 310 and sprinkler outlets 320 which spray the water over the canned beverages 101 to further cool the canned beverages 101.

[0061] To provide improved visibility of the contents within the housing 100, interior lights 130 can be installed within the housing 100.

[0062] Referring to FIG. 2 which illustrates a side view of the refrigeration system 10 shown in FIG. 1, the housing 100 can include multiple openings 120, 140 for loading and dispensing canned beverages (not shown).

[0063] Further illustrated in FIG. 2 are wheels 150 fitted to the housing 100 to improve the portability of the refrigeration system 10. By including wheels 150, the refrigeration system 10 can be transported to different venues and locations to cater for multiple events, such as shows/carnivals, fairs, sporting events and festivals. While illustrated as a portable and transportable system, refrigeration system 10 can also be a fixed installation. For example, the refrigeration system 10 can be installed at a sporting stadium replacing standard refrigeration systems.

[0064] As shown, the side walls 240 are spaced sufficiently to allow a single can laid horizontally to travel along the rack 230. However, a person skilled in the art will appreciate that the walls can be spaced sufficiently to allow any number of cans, or any other type of packaged beverage such as bottled drinks, to travel along the rack side by side.

[0065] With reference to FIG. 3, a stop 250 is formed at a lowest extent of the gravity fed dispenser 200. The stop 250 engages the canned beverage 101 to prevent unwanted further movement along the rack 230 and positions the canned beverage 101 for viewing and selection by a customer through the dispensing outlet 110.

[0066] Referring to FIGS. 2 and 3, the outlet 110 and opening 120 are of a sufficient size to allow packaged beverages to be loaded and removed from the system 10 without the need for large doors to allow access to every product contained within. Further, the outlet 110 and opening 120 can be opened and closed as needed through the use of one or more hinged doors 160.

[0067] To enhance visibility of the packaged beverages 101, external lights 170 are provided on the exterior of the housing 100.

[0068] Turning to FIG. 4, the pipes 310 can be seen to include water dispersing outlets 320. These outlets 320 disperse cooled water in a spray or mist that covers the warm canned beverages 101.

[0069] FIG. 5 shows the water disperser system 300 in use. As shown, water is sprayed from the outlets 320 such that the canned beverages 101 are covered in the cooled water.

[0070] Referring to FIG. 6, there is illustrated a cooling system 400 for cooling the interior of the housing and the water dispersed through the dispersing system. As shown, the cooling system 400 includes typical components such as a motor 401, generator 402, compressor 403, battery 404, chiller unit 406, fan 408, pump 407 and oil mixers 405 to achieve sufficient temperatures to cool the packaged beverages within the housing. The generator 402 can be any type of generator including, but not limited to, at least one of a solar powered generator, a battery powered generator and a diesel powered generator.

[0071] Advantageously, liquids provide a better medium for heat transfer than gas and thus the canned beverages can be cooled faster than in a typical refrigerator.

[0072] Further advantageously, the present invention provides an optimum combination of high storage capacity and improved cooling means.

[0073] Another advantage of the refrigeration system is that cooling time can be significantly reduced. In some instances, up to 250 cans can be cooled in an hour.

[0074] In a further advantage, in some embodiments, the refrigeration system can be transported to various venues and locations to cater for multiple events, such as shows/carnivals, fairs, sporting events and festivals.

[0075] Further advantageously, the refrigeration system can also be a fixed installation. For example, the refrigeration system can be installed at a sporting stadium to replace standard refrigeration systems.

[0076] Further advantageously, the opening for loading and dispensing can be sized sufficiently to allow beverages to be inserted and removed while minimising the amount of cold air lost to the atmosphere.
