Abstract

A mixed drink preparation apparatus includes a housing having a liquor receiving zone which receives a plurality of quantities of liquor each in its original container. The housing also receives mix containers, a water container, and a carbon dioxide container. A dispensing head is mounted on the housing and extends into a mixed drink preparation zone. A drain extends from a point in the mixed drink preparation zone beneath the dispensing head to a drain container mounted in the housing. Liquor pumps function to withdraw liquor from the liquor containers and to discharge the liquor through the dispensing head. The mix containers are pressurized with carbon dioxide gas from the carbon dioxide container, whereby mix is caused to flow through the dispensing head. A water pump withdraws water from the water container and directs the water through a liquid chilling apparatus and through the dispensing head. The water pump also directs water into a carbonating apparatus which supplies carbonated water. The flow of the various liquids through the dispensing head is regulated by valves which are in turn controlled by electronic circuitry. The electronic circuitry responds to cards each individual to a particular mixed drink to actuate the valves to effect discharge of the proper amount of each liquid necessary for the preparation of the desired mixed drink through the dispensing head. The electronic circuitry may also include counters which serve to record the quantity of liquor dispensed.
