Abstract: Disclosed is a refrigerator in which a space occupied by an evaporating dish can be minimized, evaporation efficiency of defrost water by convection-heat transfer can be improved, air can be easily exhausted in a machine room, and thus the cooling efficiency of a compressor and a condenser can be improved. The refrigerator includes: a cooling apparatus including a compressor, a condenser, and an evaporator; a blowing fan blowing air to cool at least one of the compressor and the condenser; a blowing guide duct guiding the air blown by the blowing fan to an exterior; and an evaporating dish installed in a lower portion of the blowing guide duct in order to collect and evaporate defrost water, the evaporating dish having an opened upper portion to communicate with a path of the blowing guide duct.

Abstract: A refrigerator which includes a dispenser installed at a door so as to enable a user to extract water or ice without opening a door. The dispenser includes a case forming an extraction section which is a space through which the desired object is extracted, a push button installed to the case and causing the desired object to be extracted by push operation, a cover having an opening formed by cutting out part thereof and pivotably installed to the case so as to open and close the extraction section, and a lever hinged to the cover so as to open and close the opening and pushing the push button while the opening is open. Therefore, a front appearance of the refrigerator is beautifully maintained. Further, the refrigerator prevents foreign materials such as dust from entering extraction ports through which the desired objects are extracted.

Abstract: A refrigerator including a blowing unit optimized for a bottom type condenser. The refrigerator includes a main body having a storage compartment defined therein, a condenser mounted at the bottom of the main body, and a blowing unit to blow air that has already passed through the condenser. The blowing unit includes a centrifugal fan mounted in a machine compartment and a blowing guide member to guide air blown by the centrifugal fan to the front of the main body. Consequently, it is possible to discharge the air that has already passed through the bottom type condenser, to the front of the main body, thereby accomplishing the smooth discharge of air and reducing the power consumption necessary to blow the air.

Abstract: A refrigerator including a shaved ice dispensing unit positioned within a freezing compartment door and plural ice dispensing units positioned in an ice cube container to selectively dispense ice cubes, crushed ice and shaved ice. First and second ice dispensing units are positioned in parallel in a freezing compartment. The first ice dispensing unit supplies ice cubes to the shaved ice dispensing unit, and the second ice dispensing unit selectively dispenses the ice cubes and crushed ice through an ice cube/crushed ice discharge port positioned in the freezing compartment door. The shaved ice dispensing unit includes a case having a shaved ice outlet formed therethrough, at least one blade positioned to the shaved ice outlet, a rotational barrel rotatably positioned within the case to be rotated by a driving motor and a reduction gear assembly.

Abstract: A refrigerator having a shaved ice discharger to discharge shaved ice produced within the refrigerator to an outside of the refrigerator. The refrigerator includes a body having a freezing compartment defined therein, a freezing compartment door to open and close the freezing compartment, a shaved-ice maker positioned in the freezing compartment to produce shaved ice, a shaved ice discharge port to discharge the shaved ice produced by the shaved-ice maker to the outside of the refrigerator, and a shaved ice discharger to open the shaved ice discharge port for a predetermined time. The shaved ice discharger maintains an open state of the shaved ice discharge port for the predetermined time therefore, it is not necessary to continuously apply external force to the lever, and convenience in use of the shaved-ice maker is improved.

Abstract: A water supply control apparatus and method for an ice maker, in which an amount of supplied water is controlled so as to supply an accurate amount of the water to an ice tray. The method includes the steps of (a) supplying water to an ice tray for a predetermined time; (b) determining whether or not a proper amount of water has been supplied to the ice tray after the predetermined time has elapsed; and (c) resetting the predetermined time based on predetermined water supply data, in case that it is determined that the proper amount of water has not supplied to the ice tray.

Abstract: A refrigerator with a home bar door is smoothly and automatically opened and includes an automatic opening unit, a hook unit, a latch unit, and a damping unit. The automatic opening unit pushes the home bar door to a predetermined angle, so that the home bar door is automatically opened by gravity. The hook unit cooperates with the latch unit to lock or unlock the home bar door. The damping unit includes a casing and is connected to at least one hinge shaft. The automatic opening unit is provided with a push rod and an elastic member to open by a rotation thereof. The home bar door is rotated to be opened. A rotary member is rotatably installed in the casing, with oil contained therein to reduce rotating speed of the rotary member. An associated hinge shaft engages with the rotary member to rotate along with the rotary member.
