Abstract

A defrosting assembly, a refrigerator having the same, and a method of controlling the same are provided. The refrigerator may include a food defrosting chamber, which may be divided from a food storage chamber that cools or freezes food, a defrosting device, which may be positioned in and may be removable from the food defrosting chamber, and a thermoelectric module, which may be positioned in the food defrosting chamber to heat an inside of the defrosting device and to cool an outside of the defrosting device. In a defrosting mode, frozen food may be rapidly defrosted by using the defrosting device, while in a general or a rapid cooling mode, the defrosting device may be used for food storage.
