Abstract:
1. 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 in said cooling apparatus, the cooling apparatus comprising: a case mounted on an inner wall defining the refrigerating compartment, the case defined by a front surface, a rear surface, side surfaces, an upper surface, and a lower surface having an air inlet located at a position ahead of the rear surface of the case; an agitating member that is positioned within the case and on which the container is placed, the agitating member including: 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; and a guide support of which both 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 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; an evaporating compartment positioned behind the freezing compartment; an evaporator positioned within the evaporating compartment and configured to cool air to a temperature below freezing; a suction duct of which an outlet is connected to the air inlet of the case; a suction fan assembly that is mounted on the rear surface of the case, the suction fan configured to draw cool air through the air inlet; and a return duct connected to the suction fan assembly, wherein the agitating member further includes a pair of air guides that are respectively positioned at the pair of holder shafts and face each other, and wherein the cool air from the evaporating compartment enters the case through the air inlet, flows around an outer surface of the container to exchange heat with the liquid in the container, flows rearward toward the suction fan assembly, and discharges through the return duct.
