Abstract: The present invention comprises a cooling coil configuration that permits an extended length of coil in a smaller total volume of water bath utilized, than is seen in such coils in the prior art. The coil of the present invention is made from a continuous length of stainless steel tubing that is bent in a manner to provide for the desired configuration. In one embodiment, the full coil is made up of four sub-coils generated by bending the tube through a plurality of consecutive 180 degree or semi-circular arcs having straight tubular portions intervening there between. In order of bending, there is a first large arc, a second medium sized bend of smaller circular diameter than the large bend, three consecutive small bends all of the same size and of a further smaller diameter than the medium bend, a further medium sized loop the same dimension as the previous medium one, and ending with a large loop, again of the same dimension as the first large loop.

Abstract: A carbonator comprising a tube cylinder having a closed and an open end. A disk is removably retained in the open end for providing access into the interior volume thereof. The disk provides for mounting thereto of water and carbon dioxide gas inlets, a carbonated water outlet, a safety relief valve and a water level sensor. A rigid retaining wire is bent into a square configuration wherein radiussed corners thereof cooperate with slots in the open end of the cylinder to retain the disk therein. Manipulation of the retaining wire provides for removal of the disk from the cylinder when the carbonator is not pressurized.

Abstract: An electronic control for the operation of a beverage dispenser of the refrigerated ice bank type is shown. The control provides for reliable determinations of when ice production is needed and when it is not needed. A microprocessor receives information from an ice bank probe and from a temperature probe located within the ice bank. Data collected by the microprocessor from both the ice bank probe and the temperature probe is used to determine if the ice bank is either insufficient in size and should be increased or is of sufficient size such that the compressor can be turned off. A carbonator level probe is also shown and connected to the microprocessor.

Abstract: The dispenser herein has a cold plate forming a bottom of an ice retaining bin. A bin liner is formed of two parts, a flat carbonator and a remaining U-shaped sheet metal wall structure. The carbonator and sheet metal structure when secured together form the bin liner, which, in turn, is secured to and around a perimeter edge of the cold plate and extends upward therefrom. In particular, the carbonator includes a flange integral therewith and extending from a portion of a perimeter edge thereof. A portion of the flange extends along the bottom of the carbonator for securing thereof to the cold plate, and further flange portions extend along opposite vertical carbonator edges for securing to corresponding vertical edges of the bin liner sheet metal portion. In an alternate embodiment a flat container is retained within a vertical portion of an L-shaped cold plate. A bin liner is secured to a horizontal portion of the cold plate and to the vertical portion thereof for forming an ice retaining bin.

Abstract: A narrow profile substantially flat carbonator is shown, consisting of a pair of cold drawn sheet metal halves. Each half defines corresponding alternating seams and ridges and are welded together around a perimeter them of and along each corresponding seam. When both halves are welded together the ridges define an interior plurality of vertical interior columns, which columns are fluidly interconnected with top and bottom interior channels. The too channel includes a pressure relief valve, a carbon dioxide inlet fitting, a water inlet fitting, and a level sensor fitting for retaining a level sensor. A plurality of carbonated water lines extend from the bottom of the carbonator and up along and closely adjacent a side of the carbonator. The carbonated water lines terminate at a point above the carbonator and provide for direct securing to a beverage dispensing valve.

Abstract: A beverage dispenser having a flat carbonator along one end of an ice bank cooled water bath tank. A plurality of syrup coils are arranged along an interior surface of the carbonator. An evaporator extends around a central perimeter of the water bath tank creating a central opening through which an agitator shaft and blade extend for operation by an agitator motor. The agitator shaft extends at an angle into the tank for directing a flow of water towards the carbonator. The tank includes ridges on a bottom surface thereof for directing water upward towards the carbonator and syrup coils and away from a bottom perimeter of the ice bank.

Abstract: An apparatus for providing carbonating of water. The apparatus including a carbonating tank having a carbon dioxide inlet, a water inlet, and a carbonated water outlet. The carbonating tank is pivotally mounted to a rigid structure and connected to an electric motor for providing an undulating or rocking motion of the carbonator about its pivot mounting. The motion of the carbonating tank providing for carbonating of the water held therein.
