  • Patent number: 6952937
    Abstract: An ice making machine having a main body and an auxiliary table which is separable from the main body, wherein the main body of the ice making machine comprises a freezing unit for making ice pieces by freezing water separated into discrete cells; a cooling system connected to the freezing unit; an ice bin for storing ice pieces made by the freezing unit; a first water supply pipe for supplying water to the freezing unit; and a first drain pipe for discharging water remaining unfrozen in the freezing unit. The auxiliary table comprises a feed water receptacle and a drain receptacle, both having a space for containing a predetermined level of water; a second water supply pipe selectively connected to the first water supply pipe to supply water contained in the feed water receptacle to the freezing unit; and a second drain pipe selectively connected to the first drain pipe to direct water discharged from the freezing unit to flow to the drain receptacle.

  • Patent number: 6742351
    Abstract: An ice-making machine comprises a housing, an evaporator connected to a freezing system, a base frame having a plurality of freezing cells for receiving water to be frozen, a freezing base plate on which the evaporator is disposed, the freezing base plate having a lower surface and freezing fingers formed thereon to be dipped into the water received by the freezing cells, and an air-removing means rocking the base frame to remove air bubbles from the water to be frozen. The air-removing means comprises a supporting frame for movably supporting the base frame and enabling it to rock upward and downward, a spring interposed between the base frame and the supporting frame, and a pressing means for repeatedly pressing the base frame, and the base frame being capable of rocking upward and downward due to the elastic recovering force of the spring and the pressure of the pressing means so that the water in the freezing cells are applied to the freezing fingers repeatedly.

  • Patent number: 6647739
    Abstract: An ice making machine comprising a housing, an evaporator connected to a freezing system, a base frame having a lower surface and a multiplicity of freezing cells for retaining water to be frozen, a freezing base plate provided adjacent to the evaporator and the freezing base plate having freezing fingers formed on the lower surface of the freezing base plate to be dipped into the water retained by the freezing cells, and an ultrasonic transducer for removing air bubbles inside the water by vibrating the water contained in the freezing cells with ultrasonic waves. The ultrasonic transducer preferably is disposed on the lower surface of the base frame.
