Abstract: Disclosed is an ice making apparatus and a refrigerator having the same. The refrigerator includes an ice making tray in which ice cubes are made, an ejector to discharge the ice cubes from the ice making tray, an ice bin to store the ice cubes discharged by the ejector, an auger to move the ice cubes in the ice bin, a first drive unit to provide the ejector with rotational force, a second drive unit to provide the auger with rotational force, an emitter to output optical signals so as to sense whether or not the ice cubes in the ice bin are at a full ice level, and a receiver to receive the optical signals output from the emitter, wherein any one of the emitter and the receiver is installed at the first drive unit, and the other one is installed at the second drive unit.

Abstract: A refrigerator is provided. The refrigerator includes an insulation structure and fastening structure of an ice-making compartment refrigerant pipe disposed at an inside an ice-making compartment configured to directly supply cooling energy by being in contact with an ice-making tray. The refrigerator includes an insulation member configured to surround the ice-making compartment refrigerant pipe, and a fixing member coupled to an outer circumferential surface of the insulation member in a shape of a loop to prevent the insulation member from being widened.

Abstract: A refrigerator including a main body provided with a refrigerating chamber at an upper section and with a freezing chamber at a lower section, an ice making tray disposed in an upper space of an ice making chamber defined in the refrigerating chamber, a first storage container disposed in a lower space of the ice making chamber to store ice falling down from the ice making tray, and a second storage container disposed in a freezing chamber to store ice transferred from the ice making tray. The main body includes a guide channel to guide, when the first storage container reaches an ice-full state, ice falling from the ice making tray to the second storage container in the freezing chamber. The size of the ice making chamber is greatly reduced while a sufficient amount of the ice may be stored, thus securing a larger available space in the refrigerating chamber.

Abstract: A structure of an ice making compartment of a refrigerator capable of enlarging the volume of a storage compartment by reducing a width of an ice making compartment, and capable of easily discharging the whole ice separately from pieces of ice, the refrigerator including an opening/closing member configured to open and close a portion of a discharge hole and having a cover portion to prevent the whole ice from being discharged in a state that the portion of the discharge hole is closed, the refrigerator including an opening/closing member integrally formed with a fixed blade configured to crush ice in cooperation with a rotary blade.

Abstract: A control method includes receiving an output value from an optical sensor to determine whether an ice bank is full of ice, driving the sensor heater for a first drive time to heat the optical sensor upon determining that the ice bank is full of ice, driving the optical sensor to receive an output value from the optical sensor after lapse of the first drive time, comparing the output value with the output value received to determine whether the ice bank is full of ice to calculate variation of the output value, and driving the sensor heater for a second drive time to heat the optical sensor so that the optical sensor is defrosted if the calculated variation of the output value is equal to or greater than a reference variation.
