Patent ID: 8863549

Claim:
A refrigerator comprising: a refrigerator body; a refrigerating compartment and a freezing compartment being configured to maintain operating temperatures that differ, with the freezing compartment having an operating temperature that is lower than an operating temperature of the refrigerating compartment; and a cooling apparatus that is positioned in the refrigerating compartment and that is configured to cool liquid held by a container positioned therein, the cooling apparatus comprising: a case mounted on an inner wall defining the refrigerating compartment, the case being defined by a front surface, a rear surface, side surfaces, an upper surface, and a lower surface having an air inlet; an agitating member that is positioned within the case and on which the container is placed; a power generator configured to generate a driving force to swing the agitating member the power generator comprising: a motor configured to generate rotation force; and a power transmission unit that connects a rotation shaft of the motor and, the agitating member to convert the rotation force generated by the motor to the driving force that causes the agitating member to swing over an angle, the power transmission unit comprising: a rotation member that is connected to the rotation shaft of the motor; and a rod with a first end that is connected to the rotation member and a second end that is connected to the agitating member, wherein the agitating member comprises: a front support defining a front part of the agitating member; a rear support defining a rear part of the agitating member, an upper end of the rear support being rotatably connected to the upper surface of the case; a pair of holder shafts that connect a lower end of the front support to a lower end of the rear support and that support the container; a guide support of which both lower ends are respectively coupled to the pair of holder shafts at a position between the front support and the rear support, wherein an upper end of the guide support is rotatably connected to the upper surface of the case, and a swing axis of the agitating member is configured to pass through the upper ends of the rear support and the guide support; a neck holder of which both ends are respectively coupled to the pair of holder shafts and movable along the pair of the holder shafts; and a pair of elastic members installed on the pair of holder shafts, respectively, and disposed between the neck holder and the rear support, wherein the neck holder is configured to move along the pair of holder shafts by compression of the pair of elastic members according to a size of the container, wherein when the container is placed on the holder shafts, the swing axis of the agitating member is spaced apart from the container.
