Refrigerant Evaporator Surrounding Or Within A Container Patents (Class 62/394)
  • Patent number: 4979647
    Abstract: A beverage cooling, carbonating and dispensing apparatus has a refrigerator cabinet having a cold air cooling chamber, a cold beverage reservoir and carbonator in the cooling chamber, an outlet from the reservoir to a dispensing valve, and a spring-like helically coiled thermally conductive precooler secured to a beverage inlet of the reservoir, the precooler is suspended in the cold air chamber and has a substantial restriction to flow of beverage therethrough so that the refilling flow into the reservoir is very slow and is cooled to about 40 degrees F. (4.4 degrees C.) before admittance into the reservoir, so the entire contents of the reservoir can be dispensed without warmup or loss of carbonation.

  • Patent number: 4934150
    Abstract: A method of and apparatus for controlling the thickness of an ice bank as might typically be found in the beverage dispenser field, wherein the method has the steps of attaching an ice sensor to the cooling coils of the ice bank reservoir, selecting and setting an operatively fixed but user-selectable space between the sensor and the cooling coils, freezing a portion of water to form the ice bank, sensing the formation of ice at the sensor, and controlling the freezing responsive to the sensing of ice. The apparatus is usually flat and manufactured from a single piece of injection molded plastic. Included within a first region are a curved portion for interweaving between adjacent cooling coils, and a strap for wrapping around an additional cooling coil spaced from the adjacent coils. The apparatus bends to form a substantially triangular support for the sensor. The sensor is retained by clips to the second region and extends outside of the triangular area bounded by the three portions of the apparatus.
