The ice making chamber is easily accessible by opening only the outer door while the inner door is closed and prevent cold air in the storage compartment from flowing out. ## Claims ### Claim 1 A refrigerator comprising: a body including a storage compartment; an inner door pivotably coupled to the body to open or close the storage compartment; an outer door pivotably provided in front of the inner door; a water filter accommodated in a water filter accommodation portion which is horizontally elongated between the inner door and the outer door; an ice making chamber in the inner door so as to be divided from the storage compartment by the inner door; an ice making system accommodated in the ice making chamber to make ice with water filtered by the water filter; a water tank in the inner door to store water filtered by the water filter; a dispenser including a dispensing space in the inner door through which to provide filtered water stored by the water tank and ice made by the ice making system, and a switch in the inner door to operate the dispenser; and a water supply pipe within the inner door and configured to supply water filtered by the water filter from the water filter to the water tank and from the water filter to the ice making system, wherein the dispenser is accessible through an opening of the outer door while the inner door and the outer door are closed, the ice making chamber and the water filter are accessible while the inner door is closed and the outer door is opened, and the outer door covers the ice making chamber and the water filter accommodation portion while the outer door is closed, such that the ice making system and the water filter are inaccessible. ### Claim 2 (depends on 1) The refrigerator of claim 1, wherein the ice making system comprises an ice maker provided in the ice making chamber to make ice, an ice bucket configured to store the ice, and an auger motor configured to stir or transfer the ice stored in the ice bucket. ### Claim 3 (depends on 1) The refrigerator of claim 1, further comprising: a gasket provided between the inner door and the outer door to seal the ice making chamber. ### Claim 4 (depends on 1) The refrigerator of claim 1, further comprising: a hinge pivotably coupling the inner door to the body, wherein the water supply pipe passes through the hinge and is configured to guide the water supplied from an external water supply source to the water filter. ### Claim 5 (depends on 4) The refrigerator of claim 4, wherein the hinge comprises a hinge shaft, the inner door comprises a hinge groove in which the hinge shaft is inserted, the inner door is configured to pivot with respect to the hinge shaft, and the hinge shaft comprises a through hole through which the water supply pipe passes. ### Claim 6 (depends on 1) The refrigerator of claim 1, wherein the refrigerator includes a chute configured to connect the ice making chamber to the dispensing space to guide ice in the ice making chamber to the dispensing space, the chute is comprised by an internal chute formed at the inner door and an external chute formed at the outer door, and the internal chute and the external chute are configured to communicate with each other when the outer door is closed. ### Claim 7 A refrigerator comprising: a body including a storage compartment; an inner door pivotably coupled to the body to open or close the storage compartment; an outer door having an opening and being pivotably provided in front of the inner door: a water filter accommodation portion horizontally elongated between the inner door and the outer door, in which a water filter is accommodatable to filter water supplied from an external water supply source; an ice making chamber in a front side of the inner door so as to be divided from the storage compartment by the inner door; an ice making system accommodated in the ice making chamber to make ice with water filtered by the water filter when the water filter is accommodated in the water filter accommodation portion; a water tank in the inner door to store water filtered by the water filter when the water filter is accommodated in the water filter accommodation portion; a dispenser including a dispensing space in the front side of the inner door through which to provide filtered water stored by the water tank and ice made by the ice making system, and a switch in the front side of the inner door to operate the dispenser; a water supply pipe within the inner door and configured to, with the water filter accommodated in the water filter accommodation portion, supply water filtered by the water filter from the water filter to the water tank and from the water filter to the ice making system, wherein the outer door is pivotable to a closed position in which the outer door covers the ice making chamber and the water filter accommodation portion, so that the ice making chamber and the water filter, when the water filter is accommodated in the water filter accommodation portion, are inaccessible from in front of the outer door, and the dispenser is accessible from in front of the outer door through the opening, and an opened position in which the ice making chamber and the water filter, when the water filter is accommodated in the water filter accommodation portion, are accessible from in front of the inner door. ### Claim 8 (depends on 7) The refrigerator of claim 7, further comprising: a hinge configured to pivotably couple the inner door to the body, wherein the water supply pipe is connected to the water filter through the hinge. ### Claim 9 (depends on 1) The refrigerator of claim 1, wherein the outer door is pivotably coupled to the inner door or to the body so that the outer door pivots to the opened position or the closed position while the inner door closes the storage compartment. ### Claim 10 (depends on 7) The refrigerator of claim 7, further comprising: a water filter cover that is detachably provided on an opened front side of the water filter accommodation portion. ### Claim 11 (depends on 1) The refrigerator of claim 1, further comprising: a water filter cover that is detachably provided on an opened front side of the water filter accommodation portion. ### Claim 12 (depends on 1) The refrigerator of claim 1, wherein the water filter accommodation portion longitudinally extends horizontally between the inner door and the outer door. ### Claim 13 (depends on 7) The refrigerator of claim 7, wherein the water filter accommodation portion longitudinally extends horizontally between the inner door and the outer door.
