  • Patent number: 9568228
    Abstract: There is provided an ice making method capable of forming ice to an intended level although a sensing unit configured to sense whether or not a formation of ice has reached the intended level malfunctions. The ice making method includes: an ice making initiation step S100 of forming ice by an ice formation unit; an ice release time determining step S200 of determining a point in time at which ice is to be released in consideration of a signal from a detection unit for detecting whether the formation of ice has reached an intended level and an ice making lapse time which has lapsed after the formation of ice was initiated by the ice formation unit; and an ice releasing step S300 of releasing the formed ice when a point in time at which ice is to be released is determined in the ice releasing time determining step.

  • Patent number: 9541320
    Abstract: There is provided an ice making method capable of reducing the required number of gyrations of a gyration member used for making ice to have a high level of transparency and determining a point in time at which ice is to be released. The ice making method for making highly transparent ice by revolving a gyration member provided in a tray member in which water is put such that a plurality of dipping members, on which ice is generated or from which generated ice is released, are immersed, wherein a method for driving the gyration member in making ice to be supplied to a user and a method for driving the gyration member in making ice to be used for generating cold water are different in order to reduce the number of gyrations of the gyration member.
