Definitions

  • the present disclosure relates to ice making machines. Particularly, the present disclosure relates to a system and method for harvesting ice cubes including a water inlet system in an ice making machine.
  • Conventional ice making machines include an ice making system to make ice cubes during a freeze cycle and a harvest cycle.
  • the ice making system freezes water in molds or cups in thermal communication with an evaporator to form the ice cubes.
  • the harvest cycle the ice cubes formed during the freeze cycle are removed from the cups or harvested, e.g., to a user via a dispenser or stored in an ice bin.
  • Harvest rate variation is the deviation from standard manufacturing guidelines for ice harvest that occurs when some of the individual cubes do not harvest or release from the evaporator even though all cubes may have released during initial or previous harvest cycles.
  • the issue with harvest rate variation of this nature is that a unit may appear to be functioning normally upon manufacture or install but extended run periods could potentially reduce the harvest rate to a level where ice making production is affected.
  • Harvest rate variation occurs when all of the ice cubes are not harvested from the cups of the ice making system prior to activating a water pump of the ice making system to form the ice cubes in another freeze cycle.
  • Ice cubes remaining in the cups of the ice making system can melt or become deformed as they spend more time in thermal communication with the evaporator and when the water pump restarts. This results in ice clarity and shape variation from individual cube to cube, a reduction in amount of cubes released from the evaporator during harvest cycle and decreased energy efficiency due to the fully-formed ice cubes that remain in the evaporator act as an insulator to prevent water from spraying into the empty cup and forming new ice.
  • the harvest rate exhibited by finished ice machines may still meet or exceed manufacturing line testing guidelines, but additional manufacturing line testing of the ice making machine may be needed to validate that the harvest rate will still meet the design requirements. Validating the harvest rate in this function increases labor required to manufacture the ice making machine and decreases the throughput of the number of the ice making machines through a water test area resulting in bottlenecks in the water test area.
  • the present disclosure overcomes the deficiencies of such systems by reducing harvest rate variation.
  • a method and system of dispensing water in an ice making machine that includes a tube having a plurality of tube apertures.
  • the tube receives water.
  • the water is dispensed at different locations along the tube onto different locations on an evaporator coil.
  • the evaporator coil is in thermal communication with at least one ice forming area.
  • the at least one ice forming area is positioned so that a portion of the water flows into contact therewith when ice is harvested from the ice forming area.
