at least one rotating door to open or close the storage compartment; an icemaker provided in the storage compartment; a dispenser having an ice withdrawal space, from which a user takes ice, and a water discharge hole, from which the user takes water; a filter to purify water supplied from an external water source; a water tank to store the water purified in the filter; and a valve provided at a junction of a hose where the filter is connected to the water tank and the icemaker so as to selectively supply the water purified in the filter to the water tank or the icemaker, wherein the water tank is provided at a rear surface of the door and is arranged in parallel to the dispenser such that lateral surfaces of the water tank and the dispenser are close to each other, and wherein the filter is accommodated between the dispenser and the water tank, wherein the dispenser and the water tank are provided respectively with filter receptacles, and the filter receptacles are indented to correspond to the shape of the filter for accommodation of the filter. ### Claim 2 (depends on 1) The refrigerator according to claim 1, wherein: the icemaker includes an ice discharge hole through which ice is discharged to the dispenser; the dispenser includes a chute to guide the ice from the ice discharge hole to the ice withdrawal space; and the chute of the dispenser is located close to the ice discharge hole when the door is closed. ### Claim 3 (depends on 1) The refrigerator according to claim 1, wherein the valve is located in the dispenser. ### Claim 4 (depends on 1) The refrigerator according to claim 1, wherein the water tank is detachably mounted to the rear surface of the door. ### Claim 5 (depends on 4) The refrigerator according to claim 4, wherein the water tank is provided with a hook type elastic lever for detachable mounting of the water tank and the door is provided with a holder portion which is caught and kept stationary by the elastic lever. ### Claim 6 (depends on 1) The refrigerator according to claim 1, wherein the water tank is provided at the top thereof with an entrance to allow a user to directly manually supply water into the water tank. ### Claim 7 (depends on 1) The refrigerator according to claim 1, wherein the filter is detachably mounted between the dispenser and the water tank. ### Claim 8 (depends on 1) The refrigerator according to claim 1, wherein the water tank is made of a transparent material. ### Claim 9 (depends on 1) The refrigerator according to claim 1, further comprising a valve provided at a junction of a hose where the water tank is connected to the icemaker and the dispenser so as to selectively supply water stored in the water tank to the icemaker or the dispenser to supply cooled water to the icemaker thereby reducing energy required for ice making. ### Claim 10 A refrigerator comprising a storage compartment, an icemaker provided in the storage compartment, and at least one door hingedly coupled to a lateral surface of a main body so as to open or close the storage compartment, wherein the door includes a dispenser, a filter to purify water supplied from an external water source, a water tank to store the water purified in the filter, and a valve provided at a junction of a hose where the filter is connected to the water tank and the icemaker so as to selectively supply the water purified in the filter to the water tank or the icemaker, wherein the dispenser and the water tank are arranged in parallel to each other, and wherein the dispenser and the water tank are provided respectively with filter receptacles and the filter receptacles are indented to correspond to the shape of the filter for accommodation of the filter. ### Claim 11 (depends on 10) The refrigerator according to claim 10, wherein the water tank is detachably mounted to the door. ### Claim 12 (depends on 10) The refrigerator according to claim 10, wherein the water tank is provided at the top thereof with an entrance to allow a user to directly manually supply water into the water tank. ### Claim 13 (depends on 10) The refrigerator according to claim 10, wherein the filter is detachably mounted between the dispenser and the water tank.
