## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of the Patent Korean Application No. 10-2010-0069778, filed on Jul. 20, 2010, which is hereby incorporated by reference as if fully set forth herein.
BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure
The present invention relates to a dispenser for a refrigerator and a refrigerator including the same, more particularly, to a refrigerator including a dispenser which can supply an electric power to an external device, to enhance user convenience.
2. Discussion of the Related Art
A refrigerator is an electric appliance which can maintain freshness of various foods for a long time by supplying cold air generated by a freezing cycle to a freezer compartment and a refrigerator compartment.
In general, such a refrigerator includes a cabinet having a freezer compartment and a refrigerator compartment formed therein to store foods, and doors coupled to sides of the cabinet to open and close the freezer and compartment compartments, respectively.
In addition, elements including a compressor, an evaporator, an expansion valve and the like which compose the freezing cycle may be provided in the cabinet. Cold air generated from the evaporator is supplied to the freezer and refrigerator compartments, to preserve stored food in the freezer and refrigerator compartments at a low temperature for a long time period.
In recent, a dispenser is installed in the door of the refrigerator to allow a user to dispense water or ice cubes from a water supply or an ice maker provided in the refrigerator conveniently even without opening the door. Also, cold air inside the refrigerator compartment or the freezer compartment cannot be prevented from losing although the door is opened or closed frequently.
However, the refrigerator includes only the dispenser simply in consideration of use convenience and it has a disadvantage of failing to satisfy a variety of user's demands sufficiently, while conventional electric appliances create new values via convergence with multimedia devices.
In other words, the dispenser provided in the refrigerator is used to dispense cold water cooled by cold air inside the refrigerator. In case hot water to make coffee is needed, the water dispensed from the dispenser is poured into a coffee pot and the coffee pot is connected with a power supply additionally provided, to boil the water inconveniently.
Such the inconvenience might be generated because a power supply used to supply the electric power to a boiling container such as a coffee pot is not provided in the dispenser capable of supplying cold water.
SUMMARY OF THE DISCLOSURE
An object of the present invention is to provide a refrigerator including a dispenser.
Additional advantages, objects, and features of the disclosure will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a refrigerator includes a cabinet comprising a storage compartment; a door rotatably provided in the cabinet; and a dispenser provided in the door to supply water outside the door, the dispenser comprising a power supply part which is able to be connected with an external device containing predetermined liquid, to supply an electric power to the external device.
In another aspect of the present invention, a dispenser for a refrigerator includes a dispenser case provided in a door of the refrigerator; a supply part provided in the dispenser case to supply ice or water; an opening/closing switch provided in the dispenser case to allow the ice or the water dispensed outside selectively; and a power supply part provided in a lower portion inside the dispenser case, the power supply part which is able to be connected with an external device containing predetermined liquid, to supply an electric power to the external device.
According to the present invention, there may be advantages as follows. The power supply part configured to supply the electric power to the external device is independently provided in the dispenser provided in the door of the refrigerator.
