Abstract: A refrigerator including a moisture absorbing unit configured to absorb moisture in the cold air surrounding the evaporator. The moisture absorbing unit includes a moisture absorbing material. Therefore, undesirable frosting on the evaporator can be effectively prevented. The moisture absorbing unit can be heated by a defrosting heater disposed proximate to the evaporator and the moisture absorbing unit. Thus moisture in the moisture absorbing material can be removed and the moisture absorbing material can be repeatedly used.

Abstract: The present invention provides a refrigerator capable of supplying hot and cold drinking water to a user. The refrigerator includes a cold water tank and a hot water tank and a Peltier effect thermoelectric element disposed between the tanks. When a unidirectional current is supplied to the thermoelectric element, its heat absorption portion can absorb heat from the cold water tank and cool down the water stored therein; and its heat generation portion can release to the hot water tank and heat up the water stored therein. The cold water tank can further be cooled by the cold air in the refrigerator; while the hot water tank can further be heated by the heat in the machine room.
