1. Field of the Invention
The present invention relates generally to dual compressor cooling unit. In particular, the present invention relates to a dual compressor cooling unit for maintaining multiple beverages at different temperatures.
2. Background of the Invention
Beverage cooling and storage systems are known within the art and are widely utilized in personal, retail, and service settings. In particular, refrigerated beverage display systems are widely utilized in retail settings as well as bar and restaurant settings for the marketing of particular beverages. These display systems typically consist of a refrigerated unit and a clear glass front door for displaying the contents of the refrigerated unit and possible some badging or branding of the beverage on the outside of the refrigerated unit.
Additionally, the popularity of so-called “energy” drinks has risen dramatically recently. “Energy” drinks may be thought of as soft drinks that are advertised as providing more energy than a typical drink and usually contain supplemental ingredients that are believed to contribute to increased mental alertness and/or physical performance. Typical supplemental ingredients in these “energy” drinks include caffeine, B vitamins, guarana, taurine, ginseng, inositol, carnitine, creatine, glucuronolactone, ginko boloba, and various herbs. Due to the increased mental alertness provided by many of these “energy” drinks, people have begun mixing “energy” drinks with alcoholic beverages in order to counterbalance the drowsiness induced by consuming alcoholic beverages. Although there have been some attempts at marketing beverages containing both alcohol and “energy” supplements, these combination drinks have not become very successful and are not widespread.
As such, the typical consumer who desires to consume a combination alcoholic/energy beverage usually must mix his own beverage by combining separate alcoholic and “energy” drinks. Vodka is a typical alcoholic beverage mixed with “energy” drinks due to its clear color and relative lack of odor and taste. By mixing vodka with an “energy” drink, the consumer is able to retain much of the taste and odor of the “energy” drink. Accordingly, there is a need for a single beverage cooler capable of containing and/or dispensing both alcoholic and “energy” beverages to a consumer. Additionally, since consumers often prefer extremely cold beverages and alcoholic beverages freeze at a temperature below that of water, there is a need for a single beverage cooler that is capable of maintaining “energy” beverages at cool, but above freezing temperatures, and also maintaining alcoholic beverages at temperatures below the freezing point of water.
According to an aspect of the invention a beverage cooler is provided. The beverage cooler includes a central beverage storage area and at least one external beverage dispensing unit. The central beverage storage area is generally in the shape of a cuboid, having a floor piece, ceiling piece, back piece, and two side pieces, and further having a front door piece. The external beverage dispensing unit includes an inlet, storage chamber, and outlet. The inlet may include an annular opening adapted to receive the neck of a bottle and to support the bottle in an inverted position at the bottle's “shoulder,” along with an internal retention area adapted to surround and maintain the bottleneck. The storage chamber is sealed and adapted to retain a liquid dispensed from the bottle inserted into the inlet. The outlet allows for on demand dispensing of the liquid from the storage chamber.
The beverage cooler further includes at least two compressors, wherein a first compressor is adapted to cool the central beverage storage area and a second compressor is adapted to cool at least one external beverage dispensing unit. The first compressor may cool the central beverage storage area via a forced air evaporator system. The second compressor may cool an external beverage dispensing unit via at least one cold plate, wherein the cold plate may be integrated within a wall of the storage chamber or in thermal contact with the storage chamber.
