Definitions
- the present invention relates to an ice making system and method for a refrigerator.
- a refrigerator unit is an apparatus intended to store food items at low temperatures.
- the refrigerator unit may store foods in a frozen or refrigerated state according to the types of food intended to be stored.
- the interior of the refrigerator unit is cooled by cold air that is constantly supplied.
- the cold air is constantly generated through a heat exchanging operation with a refrigerant based on a refrigeration cycle.
- the cycle includes a process of compression-condensation-expansion-evaporation that are sequentially performed.
- the cold air supplied to the inside of the refrigerator unit is evenly distributed due to convection of air to store food, drink, and other items within the refrigerator unit at desired temperatures.
- a main body of the refrigerator unit has a rectangular, hexahedral shape which is open at a front surface.
- the front surface may provide access to a refrigeration compartment and a freezer compartment defined within the body of the refrigerator unit.
- hinged doors may be fitted to the front side of the refrigerator body in order to selectively open and/or close openings to the refrigeration compartment and the freezer compartment.
- a number of drawers, racks, shelves, storage boxes, and the like may be provided in the refrigeration compartment and the freezer compartment within the refrigerator unit that are configured for optimally storing various foods, drinks, and other items within a storage space inside the refrigerator unit.
- refrigerator units were configured as a top mount type in which a freezer compartment is positioned above a refrigeration compartment.
- bottom freezer type refrigerator units position the freezer compartment below the refrigeration compartment to enhance user convenience.
- the more frequently used refrigeration compartment is advantageously positioned at the top so that a user may conveniently access the compartment without bending over at the waist, as previously required by the top mount type refrigerator unit.
- the less frequently used freezer compartment is positioned at the bottom.
- a bottom freezer type refrigerator unit may lose its design benefits when a user wants to access the lower freezer compartment on a more frequent basis.
- prepared ice that is stored in the freezer compartment may be a popular item accessed frequently by a particular user.
- the freezer compartment is positioned below the refrigeration compartment, the user would have to bend over at the waist in order to open the freezer compartment door to access the ice.
- bottom freezer type refrigerators may include a dispenser configured for dispensing ice that is provided in a refrigeration compartment door.
- the ice dispenser is also positioned in the upper portion of the refrigerator unit, and more specifically is located above the freezer compartment.
- an ice maker for generating ice may be provided in the refrigeration compartment door or in the interior of the refrigeration compartment.
- cold air that has been produced by an evaporator is divided and discharged both into the freezer compartment and into the refrigeration compartment.
- cold air that was discharged into the freezer compartment flows to the ice making device via a cold air supply duct arranged in a sidewall of the body of the refrigerator unit, and then freezes water while circulating inside the ice making device.
- the cold air is discharged from the ice making device into the refrigeration compartment via a cold air restoration duct arranged in the sidewall of the body of the refrigerator unit, so the cold air can reduce the temperature inside the refrigeration compartment.
- the efficiency of the refrigerator unit may be lessened. That is, because cold air flows to the ice making device via the cold air supply duct, and then flows from the ice making device to the refrigeration compartment via the cold air restoration duct, the efficiency of supplying cold air for the refrigerator unit may be less than optimum.
- frost may be produced in both the cold air supply duct and the cold air restoration duct due to the cold air.
- the cold air supply duct and the cold air restoration duct are not sufficiently defrosted, the cold air may not be efficiently supplied to the ice making device and the refrigeration compartment, in part due to blockage. This may cause a problem in that an excessive amount of electricity may be wasted during the operation of the refrigerator to overcome the affects of frost.
- embodiments of the present invention provide an ice making system and method for a refrigerator unit in which cold air produced from a cooling duct can be efficiently used to make ice cubes, and from which defrost water produced from the cooling duct can be efficiently drained to the outside.
- Embodiments of the present invention can also provide an ice making system and method for a refrigerator unit that can efficiently intercept outside hot air using an opening/closing unit of the cooling duct, and can increase cooling efficiency of the refrigerator unit by draining defrost water produced to the outside of the cooling duct.
- an ice making system for a refrigerator unit including: an ice making unit that makes ice cubes; a cold air generator that cools air inside a cooling duct so as to produce cold air; a cold air circulation unit that supplies the cold air from the cold air generator to the ice making unit and discharges the cold air from the ice making unit to the cold air generator; and an opening/closing unit that discharges defrost water produced from the cooling duct to the outside.
- Advantages of embodiments of the present invention include the ability of a refrigerator unit to efficiently defrost the cooling duct and efficiently drain defrost water produced during the defrosting process to the outside of the cooling duct.
- Another advantage of embodiments of the present invention includes the ability of a refrigerator unit to efficiently intercept outside hot air using the opening/closing unit of the cooling duct, and to increase the cooling efficiency of the refrigerator unit by draining defrost water produced from the refrigerator to the outside.
- a further advantage of embodiments of the present invention include the ability of a refrigerator unit to make ice cubes using the cold air directly produced from the cooling duct, thereby increasing the efficiencies of making ice and supplying cold air.
- Still another advantage of embodiments of the present invention include the ability of a refrigerator unit to circulate the cold air only a short distance within an ice making space defined between the cooling duct and the refrigeration compartment door, when compared to a conventional technique in which cold air produced from the lower part of a refrigerator unit flows to an ice making space defined in a refrigeration compartment door located in the upper part of the refrigerator unit.
- embodiments of the present invention can reduce the loss of cold air when making ice by reducing the distance of travel of cold air, thereby increasing the efficiency of the ice making unit, and saving electricity during the operation of the refrigerator unit.
