1397688 Dispensing refrigerated beverages JET SPRAY COOLER Inc 20 March 1973 [19 June 1972] 13322/73 Heading A4T [Also in Division F4] A refrigerated beverage dispenser comprises a beverage bowl 12 mounted on a base 10, a pump 14 mounted in the bowl for circulating beverage contained therein and driven by a motor 22 in the base, a hood 80 enclosing an evaporator tube 102 of a refrigeration system and having an inlet opening 100 and an outlet opening 86, and a passage 84 connecting the pump to one of the hood openings to cover beverage in the bowl, circulated by the pump, to flow through the hood in direct contact with the evaporator tube. A partition 36 divides the base into low and high pressure compartments 38, 40 and has an orifice 46 for a fan 24 driven by the motor 22 for cooling the motor and a condenser 18 and compressor 20 in the base. The motor is mounted in the base 10 with the fan 24 within the orifice 46 to draw air through perforations in the rear panel 42 of the base past the condenser 18 and over the compressor 20 and motor 22, the air escaping from the upper chamber 40 through openings in the side walls of the base. A drive magnet 96 of the motor is close to a magnet 92 of the pump 14 which is located in a recess 94 in the bottom of the bowl and draws the beverage through the opening 100 and pumps it into the passage 84 leading to the inside of a hood which encloses the evaporator 16, the beverage emerging through a tube 86 to spray against a cover 88. The beverage while within the hood is in contact with the tubes of the evaporator which are coiled and pass through openings in the bottom of the bowl. One or more solid rods 102 are disposed within the tubes to reduce the volume, and increase the velocity of the flow, of refrigerant within the tubing. The beverage is dispensed from the bowl through a spout 32 controlled by a handle 34. The evaporator may be looped between two compartments of the bowl in a twin beverage dispenser.
