     In detail, the freezer compartment  20  is defined at a lower side of the body  10  and may be selectively covered by a drawer-type freezer compartment door  22 . A space defined above the freezer compartment  20  is partitioned into left and right sides to respectively define the storage room  100  and the refrigerator compartment  30 . 
     The refrigerator compartment  30  is defined at the right side (when viewed in  FIG. 1 ) above the freezer compartment  20 . A plurality of drawers and shelves is provided inside the refrigerator compartment  30  to store foods. The refrigerator compartment  30  may be selectively opened or closed by a refrigerator compartment door  32  pivotably installed on the body  10 . 
     The refrigerator compartment door  32  has a size corresponding to that of the opened front surface of the refrigerator compartment  30 . At least portion of the refrigerator compartment door  32  is transparent to enable the refrigerator compartment  30  to be viewed through the refrigerator compartment door  32 . 
     The storage room  100  is defined at the left side (when viewed in  FIG. 1 ) of the refrigerator compartment  30 . The storage room  100  is separated from the refrigerator compartment  30  by a barrier  40 . Also, the storage room  100  may be selectively covered by a drawer-type door  150 . 
     Hereinafter, the refrigerator compartment door pivotably installed to open and close the refrigerator compartment  30  is referred to as a pivotable door. One or more drawer-type doors for opening and closing the storage room  100  are referred to one or more slidable doors. 
     When the storage room  100  provided at a side of the refrigerator compartment  30  is used as a refrigerator compartment, the refrigerator compartment door may include the pivotable door as well as the slidable door. Also, when the storage room  100  is used as the refrigerator compartment, the freezer compartment door  22  may include the pivotable door and the slidable door. When the storage room  100  is used as a switching room, the storage room  100  may be denoted as a separate switching room door. 
     In embodiments disclosed below, when the refrigerator compartment  30  and the storage room  30  are defined in one space, it is obvious to those skilled in the art that the refrigerator compartment door includes the pivotable door and the slidable door. 
     To avoid confusion in term construction, the refrigerator compartment door used in the detailed description of the present disclosure denotes the pivotable door. However, it is noted that a refrigerator compartment door noted in claims includes the pivotable door as well as the slidable door for opening and closing the storage room used as the refrigerator compartment. 
     The storage room  100  is partitioned into an upper portion and a lower portion by a partition. That is, the storage room  100  may be divided into a first storage room  100  above and a second storage room  120  below. A first door  130  and a second door  140  are withdrawably provided at the first storage room  110  and the second storage room  120 , respectively. If necessary, one storage room  100  may be provided, or two or more storage rooms  100  may be provided. 
     The first door  130  is withdrawably installed in the storage room  100 . The first door  130  may be completely inserted to completely cover the first storage room  110 . A receiving part  134  extending backwardly is disposed in a back surface of the first door  130 . 
     The receiving part  134  may have a shape similar to that of a pantry shelf. The receiving part  134  may extend up to a length corresponding to that from the back surface of the first door  130  to an inner rear surface of the first storage room  110 . The receiving part  134  may be vertically provided in two stages. Also, the receiving part  134  may be vertically provided in two or multi-stages according to kinds or shapes of received foods. 
     For example, as shown in  FIG. 2 , racks may be disposed on both sides of the receiving part  134  to seat an exclusive vessel. Also, the receiving part  134  may have a shape corresponding to that in which wine bottles and vessels are easily received. In addition, the receiving part  134  may have various structures such as a basket or shelf shape. 
     If necessary, the receiving part  134  may be provided in a single stage when the first storage room  110  is short in vertical length. Also, the receiving part  134  may be provided in two or more stages when the first storage room  100  is long in vertical length. 
     A second storage room  120  is defined below the first storage room  110 . The second storage room  120  may be separated from the refrigerator compartment  30  and the freezer compartment  20 , like the first storage room  110 . The second storage room  120  is defined above the freezer compartment  20 . 
     A second door  140  withdrawable in front and rear directions is provided on the second storage room  120 . The second storage room  120  may be selectively covered by withdrawal of the second door  140 . 
     An ice making compartment  160  may be defined in a back surface of the second door  140 . The ice making compartment  160  is a space in which ice is made, and the made ice is stored. An ice maker  162  for making at least ice is disposed inside the ice making compartment  160 . The ice maker  162  receives water to make the ice. A water supply process and an ice conveying process may be automatically performed in the ice maker. 
     When the second storage room  120  is maintained at a temperature corresponding to that of the refrigerator compartment, the interior of the ice making compartment  160  may be thermally insulated from the second storage room  120 . That is, the second storage room  120  may be thermally isolated from the ice making compartment  160  by a separate insulation structure. On the other hand, when the second storage room  120  is maintained at a temperature corresponding to that of the freezer compartment, transfer devices as well as the ice maker  162  may be received within the second storage room  120  without requiring a separate insulation or isolation structure. 
     The ice making compartment  160  may be integrally formed with the back surface of the second door  140 , and thus, may be integrally withdrawn together with the second door  140 . 
     At least portion of the ice making compartment may be selectively opened and closed to allow the ice maker  162  within the ice making compartment to be easily repaired and managed. 
     The ice making compartment  160  may be defined in a relatively lower region of the second door  140 . A receiving part  146  for receiving foods may be disposed at a rear side of the second door  140  corresponding to an upper region of the ice making compartment  160 . The receiving part  146  may have various structures, like the previously described receiving part  134  of the first door  130 .

The ice making compartment  160  protrudes backwardly from a rear surface of the second door  140 . The ice making compartment  160  is disposed in a lower portion of the second door  140 , and the receiving part  146  is disposed above the ice making compartment  160 . 
     The ice maker  162  for making ice using the supplied water and the transfer device  170  for transferring the made ice toward the dispenser  142  are disposed inside the ice making compartment  160 . 
     The ice maker  162  is disposed in a rear portion of the ice making compartment. A water supply passage and cool air duct may be separably connected to the ice maker  162  so as to supply water and cool air when the second door  140  is completely inserted. 
     If necessary, a separate water tank for storing ice making water may be disposed in the ice making compartment. The water tank may be directly filled with the ice making water by a user to supply the water to the ice maker  162 . 
     The transfer device  170  for supplying the ice conveyed from the ice maker  162  to the dispenser  142  may be disposed inside the ice making compartment  160 . The transfer device  170  supplies the water to a dispensing hole  144  defined at a position higher than that of the ice maker  162 . That is, when the dispensing hole  144  defined in the dispenser  142  is located at a position higher than that of the ice maker  162 , the transfer device  170  may be provided as shown in  FIG. 1 . The transfer device  170  may include a first transfer device  172 , a second transfer device  174 , and a third transfer device  176 . 
     In detail, the first transfer device  172  may be disposed in a lower portion of the ice maker  162 , may be parallel to the ice maker  162 , and may be operated by a motor  178 . The first transfer device  172  may have a spiral or coil shape to guide the ice conveyed from the ice maker  162  to a front side of the ice making compartment, i.e., toward the second door  140 . 
     The second transfer device  174  may be disposed at a front end portion. The second transfer device  174  may be vertically disposed parallel to the second door  140 . Also, the second transfer device  174  may be rotated by the separate motor  178 , like the first transfer device  172 . On the other hand, a front end of the first transfer device  172  may be connected to a front end of the second transfer device  174  using a medium such as a bevel gear and may be operated by a single motor. 
     The second transfer device  174  may have a spiral or coil shape to transfer the ice transferred by the first transfer device  172  to an upward direction. At this time, an upper end of the second transfer device  174  may be located at a position higher than that of the dispensing hole  144  of the dispenser  142 . 
     The third transfer device  176  may be disposed at the upper end of the second transfer device  174 . The third transfer device  176  is horizontally disposed and has a spiral or coil shape. The third transfer device  176  is rotated by the separate motor  178  to transfer the ice transferred upwardly by the second transfer device  174  to a front direction, i.e., toward the dispensing hole  144 . The second transfer device  174  may be connected to the third transfer device  176  using a medium to rotate by a single drive unit. A damper D may be disposed in the dispensing hole  144  to selectively cover the dispensing hole  144 . That is, the ice may be selectively dispensed by an operation of the damper D. 
     If necessary, the transfer device  170  may have a shape different from the spiral or coil shape. A transfer passage  180  having a diameter somewhat greater than that of the transfer device  170  may be defined inside the ice making compartment  160  to smoothly transfer the made ice along the transfer device  170 . 
     The first storage room  110  and the second storage room  120  may be used as a refrigerator compartment or a freezer compartment. The first storage room  110  and the second storage room  120  may be used as the switching room that can be converted into the refrigerator compartment or the freezer compartment by varying a temperature as necessary. At this time, the ice making compartment  160  should be formed as a completely independent insulation space within the second storage room  120 . 
     Although not shown, an evaporator for generating cool air is disposed at a rear side of the freezer compartment  20 . The cool air generated by the evaporator is supplied into the freezer compartment  20 , the refrigerator compartment  30 , the storage room  100 , and the ice making compartment  160  to cool the spaces, respectively. 
     Specifically, when the second door  140  is closed, the cool air duct for supplying the cool air may communicate with the ice making compartment  160  to perform an ice making operation in the ice maker  162  received within the ice making compartment  160 . 
     Hereinafter, an operation of the refrigerator including the above-described components will be described in detail with reference to accompanying drawings. 
     To receive the foods into the refrigerator  1 , the door is opened to store the foods in the refrigerator  1 , and then, the door is closed again. 
     Specifically, in case of the first storage room  110 , the user grasps a door handle  132  of the first door  130  to slidingly withdraw the first door  130 , thereby to open the first storage room  110 . Then, the foods may be received into the receiving part  134  disposed at a rear side of the first door  130 . After the foods are received, the first door  130  is inserted to close the first storage room  110 . 
     Similarly, in case of the second storage room  120 , the user draws a door handle  144  of the second door  140  to slidingly withdraw the second door  140 , thereby to open the second storage room  120 . When the second door  140  is withdrawn, the ice making compartment  160  integrally formed with the second door  140  is withdrawn together and is exposed to the outside. Also, the receiving part  146  disposed above the ice making compartment  160  is withdrawn together with the second door  140  and is exposed to the outside. 
     In case where the dispenser  142  is not provided in the second door  140 , when the storage room  100  is opened, at least side of the ice making compartment  160  may be opened to take the ice out of the ice making compartment  160  in a state where the second door  140  is opened. 
     The water and cool air may be supplied into the second door  140  in a state where the second door  140  is completely inserted into the second storage room  120 . Thus, after the second door  140  is completely closed, the ice is made by the ice maker  162 , and then, the made ice is dropped downwardly. 
     The ice stored below the ice maker  162  is horizontally moved by the first transfer device  172 , and then, is vertically moved by the second transfer device  174 . Then, the ice is horizontally moved by the third transfer device  176  to reach the dispensing hole  144  of the dispenser  142 . Finally, the ice transferred into the dispensing hole  144  is dispensed to the outside through a manipulation of the dispenser  142 . 
     For a service of the ice maker  162  or the transfer device  170 , the second door  140  is withdrawn to expose the ice making compartment  160  to the outside. In this state, the ice maker  162  or the transfer device  170  may be repaired, for this, the ice maker  162  and the transfer device  170  may be detachably provided. 
     For receiving the foods into the receiving part  146  of the second door  140 , the second door  140  is withdrawn to expose the receiving part  146  to the outside, and then, the foods are received into the receiving part  146 . At this time, the foods stored in the receiving part  146  are stored in a refrigerated or frozen state according to an internal temperature of the second storage room  120 .

Also, the receiving part  754  may have various structures to receive various foods. 
     A dispenser  736  for dispensing the ice supplied from the ice making compartment  760  to the outside may be disposed in a front surface of the first door  730 . The dispenser  736  may be disposed below the ice making compartment  760 , and also may be disposed at a position near to a lower end of the first door  730 . 
     That is to say, the first door  730  may have a length in which the user has access to the dispenser  736  to easily dispense drinking water and the made ice. 
     The second storage room  720  may be disposed below the first storage room  710 . The second storage room  720  may have a vertical length somewhat shorter than that of the first storage room  710 . The second storage room  720  may be maintained at a temperature corresponding to that of the refrigerator compartment or the freezer compartment. The second storage room  720  may be selectively covered by the second door  740  that is slidingly withdrawn. 
     The second door  740  has a size corresponding to that of an opened front surface of the second storage room  720 . A receiving part  744  for receiving foods may be disposed on a back surface of the second door  740 . Thus, when the second door  740  is opened, the second storage room  720  may be opened also to expose the receiving part  744  to the outside, thereby to receive the foods. 
     The receiving part  744  may have various structures according to kinds of foods. The receiving part  744  may be provided in one stage or two stages according to a vertical length of the second door  740 . 
       FIG. 13  is a front perspective view of a refrigerator according to another embodiment, and  FIG. 14  is a partial cross-sectional view of a refrigerator according to the embodiment. 
     In the present embodiment, a storage rooms is vertically partitioned, and an ice making assembly is disposed in a space different from a dispenser. Thus, the ice making assembly and the dispenser are disposed on doors different from each other, respectively. 
     Referring to  FIGS. 13 and 14 , a separate storage room for receiving a drawer-type door is provided at a lateral surface of a refrigerator compartment  30  of a refrigerator  1 , and the storage room is separated from the refrigerator compartment  30 . 
     In detail, the storage room is partitioned into a first storage room  710  and a second storage room  720  defined below the first storage room  710  by a partition  190 . The first storage room  710  is selectively covered by a first door  730 , and the second storage room  720  is selectively covered by a second door  740 . An ice making compartment is disposed on a back surface of the first door  730 , and an ice making assembly  450  is received into the ice making compartment  460 . As described above, the ice making assembly  450  includes a transfer unit including an ice maker  452 , an ice bank  454 , an auger  458 , and a crusher  457  and an electric motor  456  for operating the transfer unit. 
     In case where the first storage room  710  is used as a freezer compartment, an insulation wall structure defining the ice making compartment  710  may be not necessary. The second storage room  720  may be converted into one of the refrigerator compartment and the freezer compartment. 
     A supply duct  282  for supplying cool air and a return duct  284 , by which the cool air supplied into the ice making compartment  460  or the first storage room  710  returns to an evaporator, extend into a wall defining a body  10 . A dispenser  742  for dispensing ice stored in the ice bank  454  or drinking water is disposed in a front surface of the second door  740 . A receiving part  744  is disposed on a back surface of the second door  740  corresponding to a rear side of the dispenser  742 . According to a design method, the dispenser  736  may have a structure for dispensing only the ice, and a structure for dispensing the drinking water may be not provided. An ice making assembly  450  and/or a water tank  290  for supplying water into a drinking water dispensing hole disposed in the dispenser  742  are disposed inside the second storage room  720 . Here, a water supply passage  292  extends from the water tank  290 . Since the first door  730  and the second door  740  are slidingly withdrawn, the water supply passage  292  may be detachably coupled to the water tank  290 . That is to say, when the first door  730  and/or the second door  740  are/is withdrawn in a front direction, the water supply passage  292  may be separated from the water tank  290 . Also, when the first door  730  and/or the second door  740  are/is completely closed, the water supply passage  292  may be variably connected to the water tank  290 . At this time, a sealing structure for preventing the water from leaking through a portion connecting the water supply passage  292  to the water tank  290 . 
     An ice suit  748  for discharging the ice stored in the ice bank  454  toward the dispenser  742  is disposed in the back surface of the second door  740 . A discharge hole  461  for discharging the ice is defined at a side of a bottom surface of the ice bank  454 . In case where the ice making assembly  450  is received into the ice making compartment  450 , the discharge hole  461  may be defined in at least one bottom surface of insulation walls defining the ice making compartment  460 . A discharge duct  191  connecting the discharge hole  461  to the ice suit  748  is disposed in the partition  190 . A damper D may be disposed inside the discharge duct  191 . A distance between the ice making assembly  450  including the ice bank  454  and the ice suit  748  may be minimized to improve utilization of inner spaces of the storage rooms  710  and  720 . Thus, it is advantageous that the ice making assembly  450  is disposed at a position maximally near to a top surface of the partition  190 , and the ice suit  748  is disposed at a position maximally near to a bottom surface of the partition  190 . In case where the ice making assembly  450  and the ice suit  748  are spaced a predetermined distance from the partition  190 , an inner space of the storage room corresponding to the spaced distance may not receive foods. Thus, it is advantageous that a bottom surface of the ice making assembly  450  or the ice making room  460  is near to the top surface of the partition  190 , and an upper end of the ice suit  748  is near to the bottom surface of the partition  190 . In this case, the dispenser  742  may be disposed at a position further near to an upper end of the second door  740 . Thus, a vertical length of the dispenser  742  may extends vertically so that a position of the bottom is not changed. Therefore, a user having a small height such as a child easily dispenses the ice and water through the dispenser  742 . 
     Since the ice making compartment  460  including the ice making assembly  450  is received into the first storage room  710 , and the dispenser  742  is received into the second storage room  720 , it may obtain the following effects. That is, the ice making assembly  450  is hardly exposed to the outside of the refrigerator  1  except for a repair due to malfunction. Also, ice making efficiency may be reduced when the ice making assembly  450  is frequently exposed to the outside. Thus, to overcome the above-described limitation, the ice making assembly  450  should be disposed in a separate space within the first storage room  710 . The dispenser  742  is disposed in the second door  740 . When the second storage room  720  is maintained at a temperature corresponding to that of the refrigerator compartment, it may prevent the water supply passage  292  and the water tank  290  from being frozen over. 
     Although a separate water storage container such as the water tank  290  is disposed inside the refrigerator  1  in the present embodiment, the present disclosure is not limited thereto. For example, as shown in  FIG. 6 , the water supply passage may be directly connected to a water supply source. 
     Also, in the present embodiment, a slight modification may be applied to form the following structure. Although not shown, it is obvious to those skilled in the art that the following structure may be applicable to the present embodiment. 
     In detail, the second door  740  may be partitioned into a dispenser region and other regions to form two doors. That is, the second door  740  may be divided into two doors to cover the second storage room  720  by the second door  720 . For example, the refrigerator  1  may include a first door covering the ice making compartment  460  received into the first storage room  710 , a second door covering a portion of the second storage room  720  and including the dispenser and the receiving part, and a third door covering a portion of a lower side of the second storage room  720  and including only the receiving part. 
       FIG. 15  is a front perspective view of a refrigerator according to another embodiment, and  FIG. 16  is a partial cross-sectional view of a refrigerator according to the embodiment. 
     In the present embodiment, an ice making assembly is fixed inside a storage room, and only a dispenser is disposed on a back surface of the storage room and is withdrawn together with a door. 
     Referring to  FIGS. 15 and 16 , in a refrigerator  1  according to the present embodiment, a separate storage room is defined at a lateral surface of a refrigerator compartment  30 . The storage room is partitioned into an upper region and a lower region by a partition  190 . An ice making assembly is fixed to one of the partitioned storage rooms. 
     In detail, the storage room is partitioned into a first storage room  710  and a second storage room  720 , like the previously described embodiment. The first storage room  710  and the second storage room  720  are selectively covered by a first door  730  and a second door  740 , respectively. The first door  730  and the second door  740  are provided in a drawer-type. An ice making assembly  450  is fixed inside the first storage room  710 , and a dispenser  736  is disposed on a back surface of the second door  740 . Hereinafter, components having the same structure as those of  FIGS. 13 and 14  will be given by the same reference numerals. 
     In detail, an opened front surface of the first storage room  710  may be covered by an insulation wall  711 . The first storage room  710  may be maintained at a temperature corresponding to that of a freezer compartment  20 . An ice making assembly  450  is fixed inside the first storage room  710 . As described above, the ice making assembly  450  may include an ice maker  452 , an ice bank  454 , an electric motor  456 , a crusher  457 , and an auger  458 . The ice making assembly  450  may further include a cooling fan  459  according to a design condition. The cooling fan  459  uniformly distributes cool air supplied from a supply duct  282  to the inside of the first storage room  710  and quickly supplies the cool air into the ice maker  452 . A structure of the cooling fan  459  may be applicable in the same manner to the previously described embodiments. 
     A water tank  290  is disposed inside the second storage room  720 . A water supply passage  292  is detachably connected to the water tank  290 . Although the water supply passage  292  for supplying water into the ice maker  452  is directly connected to a water supply source along a well defining a refrigerator body  10  in the present embodiment, the present disclosure is not limited thereto. For example, the same structure as those of the embodiments shown in  FIGS. 13 and 14  may be applicable in the present embodiment. 
     In the present embodiment, a portion of the first door  730  covers a portion of an upper side of the second storage room  740 . Thus, a frame  722  for preventing cool air from leaking is disposed at a front side of the second storage room  720  corresponding to a region in which a lower end of the first door  730  is in contact with an upper end of the second door  740 . That is, a gasket disposed on a back surface of the lower end of the first door  730  and a gasket disposed on a back surface of the upper end of the second door  740  are closely attached to a front surface of the frame  722  to prevent the cool air from leaking. 
     In another embodiment, when the first door  730  has a size in which only the first storage room  710  is covered, a separate frame may be not necessary, and the partition  190  may serve as the frame. 
     Also, in the present embodiment, a dispensing structure for dispensing drinking water may be not provided in the dispenser  736 , and only an ice dispensing structure may be provided in the dispenser  736 . In this case, the water supply tank  290  and the water supply passage  292  for supplying the drinking water may be not necessary. 
     According to the above-described structure, like the previously described embodiment, when the first door  730  is withdrawn, the ice making assembly  450  is maintained in a state in which the ice making assembly  450  is fixed inside the first storage room  710 . That is, since the ice making assembly  450  need not be frequently exposed to the outside by a user, the ice making assembly  450  is not exposed to the outside even if the doors  730  and  740  are withdrawn. 
     In the present embodiment, since the ice making assembly  450  is fixed inside the first storage room  710 , a separate insulation wall structure surrounding the entire ice making assembly  450  need not be provided. That is, it may be enough to provide only the insulation wall  711 . However, a separate insulation wall defining the ice making compartment may be provided according to a design condition. The insulation wall  711  may be pivotably provided about an upper end thereof to allow the ice making assembly  450  to be separated. 
     The two doors for respectively opening and closing the first storage room  710  and the second storage room  720  may be integrally formed in one body. That is, the first door  730  and the second door  740  are not divided, i.e., a single door may be provided to selectively open and close the first storage room  710  and the second storage room  720 . This structure is referred to as a plurality of storage rooms/single door structure. In this case, when the second storage room  720  is opened, the first storage room  710  may be opened together. However, the insulation wall  711  may prevent an external air from being introduced into the first storage room  710 . Also, in case of the single door structure, the frame  722  need not be provided. 
     On the other hand, the first door  730  may be divided into two doors. 
     In detail, the first door  730  may be divided into an upper door for covering only the ice making compartment  710  and a lower door including the dispenser. The upper door may open and close the ice making compartment instead of the insulation wall  711 . A dispenser  736  may be disposed in the lower door, and a receiving part may be disposed at a rear side of the dispenser  736 . Thus, the second storage room  720  may be opened and closed by the lower door including the dispenser  736  and the second door  740 . This structure is referred to as a plurality of storage rooms/a plurality of doors structure. That is, one door may open and close a portion or the whole of one storage room. 
       FIG. 17  is a front perspective view of a refrigerator according to another embodiment, and  FIG. 18  is a partial cross-sectional view of a refrigerator according to the embodiment. 
     In the present embodiment, an ice making assembly is fixed inside a storage room, and only a dispenser is disposed on a back surface of a door for opening and closing the storage room. Thus, the storage room forms one space. 
     Referring to  FIGS. 17 and 18 , a refrigerator  1  according to the present embodiment includes a refrigerator compartment  30 , a freezer compartment  20 , and a storage room  760  defined at a side of the refrigerator compartment  30 . 
     In detail, the storage  760  is provided in one space, and an ice making compartment  460  is defined above the storage room  760 . As described above, the ice making compartment may be separated from the storage room  760  by a separate insulation wall structure. According to the separate insulation wall structure, an internal temperature of the ice making compartment  460  may be different from that of the storage room  760 . An ice making assembly  450  is received into the storage room  760 . The storage room  760  includes an ice maker  452 , an ice bank  454 , an electric motor  456 , a crusher  457 , and an auger  458 , and/or a cooling fan  459 . A front surface of one of insulation walls defining the ice making compartment  460  may be pivotably disposed about an edge portion of a side thereof to allow the ice making assembly  450  to be separated. A discharge hole  461  for discharging ice is defined in a bottom surface of one of the insulation walls defining the ice making compartment  460 . 
     An opened front surface of the storage room  760  is selectively covered by a door  750 . The door  750  may have a configuration and size in which the first door and the second door of the previously described embodiment are integrally formed in one body. A dispenser  736  is disposed at a side of the door  750 . That is, a recess portion for receiving a container is disposed on a front surface of the door  750 , and an ice suit  748  for guiding a discharge of ice is disposed in a back surface of the door  750 . When the door  750  is completely closed, an upper end of the ice suit  748  communicates with the discharge hole  461 . Thus, the ice discharged from the ice bank  456  passes through the discharge hole  461 , is guided by the ice suit  748 , and is discharged from the dispenser  736 . 
     Although not shown, the ice making compartment  460  may be disposed on the back surface of the door  750  to provide a structure in which the ice making compartment  460  is withdrawn together with the door  750 . This will be construed as being included in the present disclosure. 
     Also, the door  750  may be partitioned into two doors, and the storage room  760  may be also partitioned into two storage rooms. It may be easily modified from  FIGS. 17  and  18  by those skilled in the art. That is to say, the door  750  may be partitioned into a first door including the dispenser  736  and/or the receiving part and a second door including only the receiving part. Also, the storage room  760  corresponding to the door  750  may be partitioned into a first storage room receiving the ice making assembly  460  and a rear end portion of the dispenser  736  and a second storage room receiving the receiving part disposed on the second door. Thus, the partitioned first storage room may be opened and closed by the first door, and the partitioned second storage room may be opened and closed by the second door. Of course, the ice making assembly  460  is fixed inside the partitioned first storage room. This structure is referred to as a plurality of storage rooms/a plurality of doors structure. Thus, one door may open and close one storage room. 
       FIG. 19  is a front perspective view of a refrigerator according to another embodiment, and  FIG. 20  is a partial cross-sectional view of a refrigerator according to the embodiment. 
     In the present embodiment, a storage room separated from a refrigerator compartment and a freezer compartment and a door for opening and closing the storage room are provided in one space and a single door to provide only a dispenser for dispensing drinking water within the door. 
     Referring to  FIGS. 19 and 20 , a body  10  of a refrigerator  1  according to the present embodiment includes a refrigerator compartment  30 , a freezer compartment  20 , and a storage room  760 . The storage room  760  is covered by a drawer-type door  750  that is slidingly withdrawn. 
     In detail, at least one or more receiving parts are disposed on a back surface of the door  750 . A variety of containers is seated on the receiving parts  754 . A dispenser  756  having a recessed shape and dispensing drinking water is disposed in a front surface of the door  750 . A water supply passage  292  extends up to a top surface of the dispenser  756 . 
     In further detail, a water tank  290  is disposed inside the storage room  760 . The water supply passage  292  extends from the water tank  290  up to the dispenser  256 . As shown in  FIG. 20 , the separate water tank  290  for supplying the drinking water may be provided. Alternatively, the water supply passage  292  may be directly connected to a water supply source. 
     The water supply passage  292  has one end detachably connected to the water tank  290 . Thus, when the door  750  is opened, the water supply passage  292  is separated from the water tank  290 , and when the door  750  is completely closed, the water supply passage  292  is coupled to the water tank  290 . 
     Although the dispenser  756  is disposed at an upper portion of the door  750  in the present embodiment, the present disclosure is not limited thereto. For example, like a dotted portion shown in  FIG. 19 , the dispenser  756  may be disposed at a position near to the door  750 . Therefore, a user having a small height such as a child may easily dispense ice and water. 
     Also, although a dispenser for dispensing ice is not provided, and only a dispenser for dispensing drinking water is provided in the present embodiment, as well as, the door  750  for opening and closing the storage room  737  is provided in only one as an example, the present disclosure is not limited thereto. For example, the door  750  for opening and closing the storage room may be provided in plurality, like the previously described embodiment. 
     For example, doors for opening and closing the storage room may be disposed at upper and lower sides, respectively, and a dispenser for dispensing the drinking water may be disposed on any one door. Also, the storage room  760  may be partitioned into a plurality, and the partitioned storage rooms may be maintained at temperatures different from each other. 
       FIG. 21  is a vertical cross-sectional view of a refrigerator according to another embodiment,  FIG. 22  is a bottom perspective view illustrating a first door of a refrigerator according to the embodiment, and  FIG. 23  is a rear perspective view illustrating a second door of a refrigerator according to the embodiment. 
     Referring to  FIGS. 21 to 23 , in the present embodiment, a first door  730  covers the whole of a first storage room  710  and a portion of a second storage room  720 . A second door  740  covers a remaining portion of the second storage room  720 . Moreover, an ice making assembly  450  is disposed on a back surface of the first door  730  corresponding to a region in which the portion of the second storage room  720  is covered. A dispenser  746  for dispensing ice and/or water is disposed in a front surface of the second door  740 . 
     In the present embodiment, a water supply passage  292  for supplying the water into an ice maker  452  and the dispenser  746  is directly connected to a water supply source. When the first door  730  and/or the second door  740  are/is withdrawn, the water supply passage  292  is separated at any position, and the water supply is stopped by an opening/closing valve V disposed at the separated position. 
     A partition or a frame may be not provided between a lower end of the first door  730  and an upper end of the second door  740 , and a pillar  50  may be pivotably disposed on a back surface of the lower end of the first door  730 . A structure and operation of the pillar  50  will be described below in detail with reference to accompanying drawings. 
     A discharge duct  462  for guiding a withdrawal of ice is disposed at a front side of a bottom surface of the ice making assembly  450  and extends toward the dispenser  740 . In detail, an ice suit  748  for guiding the withdrawal of the ice is disposed at an upper side of the dispenser  740 . An end portion of the discharge duct  462  extends near to an inlet port of the ice suit  748 . 
     The discharge duct  462  does not extend below an upper end of the second door  740 . That is, an end portion of the discharge duct  462  may maximally extend up to a plane L 1  horizontally parallel to the upper end of the second door  740 . This is done because it prevents the discharge duct  462  form interfering with the second door  740  when the first door  730  is opened in a state where the second door  740  is closed. 
     The inlet port of the ice suit  748  protrudes toward the discharge duct  462 . However, the inlet port does not extend above a plane L 2  horizontally parallel to a lower end of pillar  50 . That is, this is done because it prevents the inlet port of the ice suit  748  from interfering with the pillar  50  when the second door  740  is opened in a state where the first door  730  is closed. 
     Dampers D may be disposed inside the discharge duct  462  and the ice suit  748 , respectively, to prevent the ice from being dispensed when any one of the first door  730  and the second door  740  is opened. 
     As a result, the end portion of the discharge duct  462  is not closely attached to the inlet port of the ice suit  748 . Thus, the dampers D may be manipulated to prevent cool air supplied into an ice maker  460  from leaking into the second storage room  720  or the dispenser  746 . For this, a passage formed by the discharge duct  462  and the ice suit  748  is covered by the dampers D, except when the ice is dispensed. 
     The end portion of the discharge duct  462  has an inside diameter d 1  equal to or less than that of the inlet port of the ice suit  748  to prevent a portion of the ice from being introduced into the second storage room  720 . 
     Referring to  FIG. 21 , a rail member  60  may be disposed on both lateral surfaces of the receiving part  734 . The rail member may  60  be withdrawn in multi-step. That is, the rail member  60  include fixed rails  61  respectively fixed to the both lateral surfaces of the receiving part  734  and a movement rail  62  movably connected to the fixed rails  61 . A support structure for slidingly supporting the rail member  60  may be disposed on an inner sidewall of the second storage room  720 . The rail member  60  has the same structure as or is similar to a rail member that will be described in detail in the following embodiment. 
       FIG. 24  is a side cross-sectional view of a refrigerator according to another embodiment. 
     Referring to  FIG. 24 , a refrigerator according to the present embodiment has the same structure as that shown in  FIG. 21 , except that an ice making compartment  460  is fixed inside a storage room. 
     As shown in  FIG. 24 , the ice making compartment  460  is fixed to a rear surface of a second storage room  720 , and an ice making assembly  450  is received into the ice making compartment  460 . Thus, a portion of an upper side of the first door  730  covers the whole of the first storage room  710 , and a portion of a lower side of the first door  730  covers a portion of the second storage room  720 . A dispenser  746  is disposed on a back surface of the second door  740 , and the second door  740  covers the remaining portion of the second storage room  720 . 
     A discharge duct  462  extends from a bottom surface of the ice making compartment  460 , and an end portion of the discharge duct  462  extends toward an ice suit  748  disposed above the dispenser  746 . That is to say, the discharge duct  462  may inclinedly extend in a front direction up to an inlet port of the ice suit  748 . This is done because the ice making compartment  460  is not moved even if the first door  730  is withdrawn forwardly, and because it does not matter that the end portion of the discharge duct  462  extends up to a position lower than that of an upper end of the second door  740 . This is different from the embodiment of  FIG. 21 . Thus, since a distance between a lower end of the discharge duct  462  and an inlet of the ice suit  748  may be minimized, leakage of cool air may be minimized. Of course, in case of the present embodiment, dampers D may be disposed inside the discharge duct  462  and the ice suit  748 , respectively. 
       FIGS. 25 and 26  are partial perspective views of a power supply structure connected to a water supply passage and a dispenser provided in a refrigerator according to an embodiment, and  FIG. 27  is a cross-sectional view taken along line B-B of  FIG. 26 . 
     A water supply passage and a wire shown in  FIGS. 25 to 27  may be commonly applicable to all of the previously described embodiments and the following embodiments. It is to be understood that the water supply passage is merely illustrative of one of various embodiments. A structure of a refrigerator, based on the structure of the refrigerator shown in  FIG. 21 , will be described below. 
     Referring to  FIG. 25 , a water supply passage  292  extending from a water tank or a water supply source extends along a sidewall of a refrigerator body  10 . The water supply passage  292  extends up to a front surface of the sidewall of the refrigerator body  10 , and an opening/closing valve V is disposed at an end portion of the water supply passage  292 . 
     Referring to  FIG. 26 , a water supply passage  292  for dispensing drinking water within a second door  740  extends toward a dispenser. An end portion of the water supply passage  292  protrudes from an edge portion of a back surface of the second door  740 . The end portion of the water supply passage  292  is selectively coupled to the opening/closing valve V. That is, when the second door is completely closed, the water supply passage of the refrigerator body  10  and the water supply passage of the second door  740  are connected to each other, and the opening/closing valve V is opened. 
     Although only the water supply passage for dispensing the drinking water extends along the refrigerator body in the present embodiment, the present disclosure is not limited thereto. For example, when an ice making compartment is fixed to the first door or the second door, a water supply passage for making ice may be realized also using the same manner. 
     As described above, rail members  60  are disposed on both lateral surfaces of a portion corresponding to a bottom surface of a receiving part  734 . A wire P extends inside one rail member  60  and is connected to a controller (not shown) for operating a display or dispenser disposed in the second door  740 . 
     Referring to  FIG. 27 , the wire P extends inside a fixed rail  61  fixed to a lateral surface of the receiving part  734 . The wire P may be wound in a spiral shape and have a predetermined elasticity. Thus, the wire P may extend according to forward and backward movements of the second door  740 , and then, returns to prevent the wire from being damaged. 
       FIGS. 28 and 29  are partial perspective views of a power supply structure connected to a dispenser of a refrigerator according to another embodiment. 
     Referring to  FIGS. 28 and 29 , a refrigerator according to the present embodiment has the same structure as that shown in  FIGS. 25 and 26 , except for a power supply structure. Thus, duplicated descriptions of other components except for the power supply structure will be omitted. 
     In detail, in the present embodiment, a wire P extends along an inner sidewall of a refrigerator body  10 . A socket  600  may be disposed on a front surface of the sidewall of the refrigerator body  10 , i.e., a surface in contact with a back surface of a first door  730  or a second door  740 . The wire P is connected to the socket  600 . 
     A plug  601  may protrude from a surface corresponding to the socket  600  of the back surface of the second door  740  (or the first door  730 ). A battery  602  for an electric charging may be laid inside the second door  740  and be connected to the plug  601 . The battery  602  is electrically connected to a controller for controlling operations of a display attached to a front surface of the second door  740  and other electric components. It is obvious that the plug  601  may be disposed on the refrigerator body  10 , and the socket  600  may be disposed on the second door  740 . 
     When the second door  740  is completely closed, the plug  601  is inserted into the socket  600 . Thus, current flows to charge the battery  602 . When the second door  740  is withdrawn forwardly, the plug  601  is separated from the socket  600  to stop the charging. 
     When the second door  740  is completely closed, a variety of electric components including the display disposed on the second door  740  is operated by the current supplied through the wire p. On the other hand, when the second door  740  is opened, the display and other electric components are operated by the current supplied from the battery  602 . 
       FIGS. 30 and 31  are partial perspective views of a refrigerator according to another embodiment.

     In detail, an ice making compartment  770  is vertically disposed on a back surface of the second door  740 . An ice making compartment door  771  is pivotably disposed on a side of the ice making compartment  770 . 
     An ice maker  452  and an ice bank  454  constituting an ice making assembly  450  are received into the ice making compartment  770 . An auger  458  and a crusher  457  are provided inside the ice bank  454 . An electric motor (not shown) for operating the auger  458  and the crusher  457  may be laid inside the second door  740 . In detail, the ice maker  452  may be disposed on an inner top surface of the ice making compartment  770 , and the ice bank  454  may be detachably disposed direct below the ice maker  452 . A dispenser  746  including an ice suit  748  is disposed at a lower side of the ice bank  454 . That is, the ice bank  454  may be detachably disposed on a top surface of the dispenser  748 . The ice bank  454  may be slidingly movable laterally from the top surface of the dispenser  748 . Thus, a user may open the ice making compartment door  771  to easily separate the ice bank  454  from a refrigerator in a state where the second door  740  is withdrawn. 
     Although a transfer unit including the auger  458  and the crusher  457  extends forwardly and backwardly in the present embodiment, the present disclosure is not limited thereto. For example, a vertical auger structure disclosed in U.S. Issued U.S. Pat. No. 6,082,103 may be applicable to the present embodiment. Also, an auger structure, in which a rotation axis is inclined, disclosed in Korean Published Applications No. 2008-0053503 may be applicable to the present embodiment. Here, the rotation axis may extend in a direction crossing the second door  740  and may be inclined in up and down or left and right directions. Or, the rotation axis may extend in a direction parallel to the second door  740  and may be inclined in a vertical direction. 
     A pair of water supply passages  292  within sidewalls of a second storage room  720  opened and closed by the second door  740  may extend in a front direction, and opening/closing valves V may be disposed at front ends of the water supply passages  292 . End portions of the water supply passages selectively coupled to the opening/closing valves V may protrude from an edge portion of a back surface of the second door  740 . Since structures of the water supply passages ware previously described, duplicated descriptions thereof will be omitted. 
     A receiving part  744  may be disposed at a rear side of the ice making compartment  770 , and rail members may be disposed on both lateral surfaces of the receiving part  744  to allow the second door  740  to be withdrawn forwardly. 
       FIG. 32  is a perspective view illustrating a structure of an ice-making assembly of a refrigerator according to an embodiment. 
     Referring to  FIG. 32 , an overflow prevention unit is illustrated in the present embodiment. The overflow prevention unit prevents water supplied into an ice making assembly from overflowing due to an inertial force generated when a storage room door is moved forwardly and backwardly. 
     In detail, an ice maker  452  is disposed horizontally or vertically inside an ice making compartment  460 . A water supply passage  292  extends in a direction crossing the ice making compartment  460  toward the ice maker  452 . 
     A discharge hole  461  is defined in a bottom surface of the ice making compartment  460 . Also, a guide member is disposed to transfer ice separated from the ice maker  452  toward the discharge hole  461 . The guide member may include a guide plate  459  extending from a lateral surface of the ice maker  452 . In detail, the guide plate  459  inclinedly extends downwardly from a lateral end of a top surface of the ice maker  452  to approach to the discharge hole  461 . 
     An overflow prevention part  453  may extend from an edge portion of the top surface of the ice maker  452 . In detail, in case where the ice making compartment  460  is disposed on a storage room door, water stored in the ice maker  452  may overflow due to inertia when the storage room door is moved forwardly and backwardly. The overflow prevention part  453  may be provided to prevent the water from overflowing. The overflow prevention part  453  may have a structure in which water overflowing by the inertia returns again to the ice maker  452 . That is, the overflow prevention part  453  may extend in a direction crossing an inertia direction, and an upper portion thereof may be rounded. Thus, the water soars upwardly from the ice maker  452  flows along an inner surface of the overflow prevention part  453  to return again to the ice maker  452 . The overflow prevention part  453  may have various shapes according to an internal structure of the ice making compartment  460  and an installation direction of the ice maker  452 . Alternatively, a residual water tray for receiving the overflowing water may be disposed on a bottom surface of the ice maker  452 . 
     In the present disclosure, the ice making assembly may be defined as an ice making mechanism, as well as, a structure including the ice making assembly and the ice making compartment may be inclusively defined also as the ice making mechanism. That is, a structure including at least ice making assembly may be defined as the ice making mechanism. It may be widely construed that the ice making compartment denotes a physical configuration such as an insulation wall structure surrounding the ice making assembly as well as an inner space defined by the insulation wall structure. 
     Also, the storage room disclosed in the present disclosure, i.e., the first storage room and the second storage room may be used as one of the refrigerator compartment and the freezer compartment. In addition, the storage room may be used as the switching room in which the refrigerator compartment and the freezer compartment may be mutually converted according to a user s selection or a driving condition. 
     In a structure of the refrigerator according to the previously described embodiments, the slidable door that is movable in forward and backward directions, but the pivotable door, is provided at a side of the refrigerator door. Thus, when the refrigerator is installed at an edge portion of an indoor space, a door closely attached to a wall is not rotated at an angle greater than about 90 degrees. However, the prevent disclosure may overcome such a limitation. 
     Also, the storage room disclosed in the present disclosure has a width relatively narrower than the refrigerator compartment. However, since long containers such as a bottle may be easily received into the storage room, space utilization of the inside of the refrigerator may be improved. 
       FIG. 33  is a perspective view illustrating an outer appearance of a refrigerator according to an embodiment, and  FIG. 34  is a perspective view of a refrigerator when a refrigerator door is opened, according to an embodiment. 
     Referring to  FIGS. 33 and 34 , a refrigerator of the present embodiment is almost similar to those of  FIGS. 1 and 2 .

     A plurality of shelves  12  and drawers  14  is provided inside the refrigerator compartment  30  to store foods. The shelves  12  and drawers  14  are disposed at a rear side of the refrigerator door  32  and have horizontal widths less than that of the refrigerator compartment door  32 . Thus, when only the refrigerator compartment door  32  is opened, each of the drawers  14  and shelves  12  may be withdrawable without interfering. 
     The shelf  12  is detachably disposed in a cantilever manner on an inner rear surface of the refrigerator compartment  30 . Also, the shelf  12  may be detached at an inner space of the refrigerator compartment  30  to adjust a height thereof. 
     The first door  130  and the second door  140  are disposed at a left side of the refrigerator compartment door  32  to cover a left space of the refrigerator compartment  30 . The first door  130  may be disposed above the second door  140 . 
     The first door  130  and the second door  140  may be withdrawable in a drawer-type. Door handles  132  and  144  may be disposed on front surfaces of the first door  130  and the second door  140 . Receiving parts (reference numerals  134  and  146  of  FIG. 3 ) for receiving foods may be disposed at a rear side of the first door  130  and the second door  140 . An ice making compartment (reference numeral  160  of  FIG. 3 ) for making and storing ice is disposed at the rear side of the second door  140 . 
     A dispenser  142  for dispensing drinking water and the ice at the outside is disposed in a front surface of the second door  140 . The dispenser  142  communicates with the ice making compartment  160  to dispense the ice stored in the ice making compartment  160  at the outside and is connected to an external water supply source by a water supply passage to dispense the drinking water. 
     Dispensing holes for respectively dispensing the made ice and the drinking water and a manipulation unit may be disposed in the dispenser  142 . A residual water tray for receiving residual water generated when the ice or the drinking water is dispensed may be disposed below the dispenser  142 . A display for illustrating an operation state of the refrigerator may be disposed above the dispenser  142 . 
       FIG. 35  is an exploded perspective view of a refrigerator when a first door and a second door are withdrawn, according to an embodiment, and  FIG. 36  is a cross-sectional view taken along line C-C of  FIG. 35  when the first door is closed.

The withdrawal guide  42  protrudes to contact with a lateral surface of the slidable door. That is, the withdrawal guide  42  is in contact with a lateral upper end or lower end of the slidable door. In addition, the withdrawal guide  42  may be disposed in front and rear directions to stably guide the slidable door during the withdrawal of the slidable door. 
     If necessary, the rail mounting member  70  and the rail member  60  may be disposed on the withdrawal guide  42 . The withdrawal guide  42  may be disposed without covering foods received in the slidable door. 
     An ice making compartment  160  for making and storing ice is disposed at a lower side of a back surface of the second door  140 . The ice making compartment  160  communicates with the dispenser  142 . If necessary, an additional rail member  60  for guiding the withdrawal of the second door  140  may be further provided between a left side surface of the ice making compartment  160  and a right side surface of the drawer  14 , which are adjacent to each other. 
     The ice making compartment  160  may be disposed at an upper or lower portion of the second door  140 . Thus, the receiving part  146  may be disposed also at the upper or lower portion of the second door  140 . 
       FIG. 37  is a perspective view of a refrigerator when a first door is opened, according to another embodiment,  FIG. 38  is a cross-sectional view taken along line C-C of  FIG. 37  when the first door is closed, and  FIG. 39  is a bottom perspective view of a first door according to another embodiment. 
     Referring to  FIGS. 36 to 39 , a refrigerator of the present embodiment has the same structure as that of  FIG. 8 , except that a separate barrier for partitioning the inside of the refrigerator is not provided, the refrigerator defined as one space is covered by a refrigerator compartment door, a first door, and a second door, and a pillar is disposed between the first door and the second door. 
     In detail, a body  10  is vertically partitioned into a refrigerator compartment  30  and a freezer compartment  20 . A portion of the refrigerator compartment  30  is covered by a refrigerator door  32 , and another portion of the refrigerator compartment  30  is covered by a first door  430  and a second door  440 . 
     The refrigerator compartment door  32  is coupled to the body  10  using a hinge  34 , and thus is pivotally opened and closed. A portion of a front surface of the refrigerator compartment door  32  may be transparent to enable the refrigerator compartment  30  to be viewed through the refrigerator compartment door  32 . The first door  430  and the second door  440  may be vertically disposed at a side of the refrigerator compartment door  32 . The first door  430  and the second door  440  may be disposed inside the refrigerator compartment  30  and slidingly withdrawn by a rail member  60 . 
     The rail member  60  for withdrawing the first door  430  is disposed on inner upper and left side surfaces of the refrigerator compartment  30  to support and slidingly move the first door  430 . The rail member  60  for withdrawing the second door  440  is disposed on inner lower and left side surfaces of the refrigerator compartment  30  to support and slidingly move the first door  430 . 
     Receiving parts  434  and  442  for receiving foods are disposed on the first door  430  and the second door  440 . A dispenser  436  for dispensing water and ice is disposed in a front surface of the first door  430 . Considering a height of a user, the dispenser  436  may be disposed at a lower side of the first door  430 . 
     An ice making compartment  460  is disposed at an upper side of the first door  430 . An ice maker  452  and an ice bank  454  are received into the ice making compartment  460 . The ice making compartment  460  may be formed with an independent insulation space within the refrigerator compartment  30 . 
     The ice making compartment  460  may be detachably coupled to a back surface of the first door  430  and may be integrally formed by a door liner defining the back surface of the first door  430 . 
     The ice making compartment  460  may extend from the back surface of the first door  430  toward a rear direction, and thus may be adjacent to a rear surface of the refrigerator compartment  30 . Also, when the first door  430  is completely inserted, a cool air duct  480  disposed inside the body  10  communicates with the inside of the ice making compartment  460 . 
     In detail, the cool air duct  480  includes a supply duct for guiding cool air into the ice making compartment  460  and a return duct for guiding the cool air toward an evaporator. A cool air inlet  462  and a cool air outlet  464  are defined in a rear wall of the ice making compartment corresponding to the supply duct  482  and the return duct  484 , respectively. 
     Thus, when the first door  430  is completely inserted, the supply duct  484  may communicate with the cool air inlet  462 , and the return duct  484  may communicate with the cool air outlet  464  to continuously circulate the cool air between the ice making compartment  460  and the evaporator. 
     An auger  458  operated by an electric motor  456  and a crusher  457  disposed on the same rotation axis to crush the ice are disposed in the ice bank  454  within the ice making compartment  460 .

A valve may be disposed in the water supply passage. 
     Gaskets  438  for preventing the cool within the refrigerator compartment  30  air from leaking are disposed on back surfaces of the first door  430  and the second door  440 . A pillar  50  is disposed at a position adjacent between the first door  430  and the second door  440 . 
     The pillar  50  covers a space between the first door  430  and the second door  440 . The pillar  50  is disposed at a lower end of the back surface of the first door  430 . The pillar  50  is selectively pivoted according to the withdrawal of the first door  430  to selectively cover the space between the first door  430  and the second door  440 . 
     In detail, the pillar  50  has a length corresponding to a horizontal width of the first door  430 . When the first door  430  is inserted, the pillar is pivoted. As a result, a lower end of the first door  430  and an upper end of the second door  440  are in contact with a front surface of the pillar  50  to prevent the cool air within the refrigerator compartment  30  from leaking between the first door  430  and the second door  440 . 
     The pillar  50  is hinge-coupled to the lower end of the first door  430 . The pillar  50  is closely attached to the first door  430  by an elastic member  52  in a state where the front surface of the pillar  50  is inclined downwardly when an external force is not applied to the elastic member  52 . The pillar  50  may be covered by a front surface of the first door  430 . Thus, the pillar  50  may be not exposed to the outside when viewed from a front direction of the first door  430 . 
     The elastic member  52  disposed in the pillar  50  may have a coil spring shape. The elastic member  52  may connect the pillar  50  to a side of the first door  430 . The pillar  50  may be closely attached the lower end of the first door  430  due to elasticity of the elastic member  52  if the external force is not applied to the pillar  50 . 
     The elastic member  52  may have various shapes except for the coil spring shape. Also, the elastic member  52  may be disposed at various positions to provide an elastic force to the pillar  50 . 
     A guide protrusion  54  protruding outwardly is disposed at one end of the pillar  50 . The guide protrusion  54  may moved along a guide groove  70  defined in a lateral surface corresponding to the inside of the refrigerator compartment  30 . Surfaces of the guide groove  70  and the guide protrusion  54 , which correspond to each other, may be rounded with a predetermined curvature to smoothly rotate the pillar  50 . 
     In detail, the guide groove  70  is opened in a front direction and is depressed inwardly. The guide groove  70  is curved inwardly with a predetermined curvature. A curved part  56  corresponding to the curvature of the guide groove  70  is disposed on the guide protrusion  54  contacting with the guide groove  70 . Thus, when the guide protrusion  54  of the axially coupled pillar  50  is moved along the guide groove  70  fixed to an inner wall of the refrigerator compartment  30 , the pillar may be rotatable. 
       FIG. 40  is a view illustrating successive operations of a pillar according to another embodiment. 
     Referring to  FIGS. 37 and 40 , when the first door  430  is opened, the front surface of the pillar  50  is inclined downwardly due to an elastic restitution force applied by the elastic member  52 . 
     When the first door  430  is inserted in a rear direction, the curved part  56  of the guide protrusion  54  contacts with the guide groove  70 . When the first door  430  is further inserted, the pillar  50  is moved backwardly along the first door  430  to rotate about a rotation axis in a count-clockwise direction. At this time, the curved part  56  disposed on the guide protrusion  54  is slidingly moved along an inner surface of the guide groove  70 . 
     When the first door  430  is completely inserted, the curved part  56  of the guide protrusion  54  is completely rotated along the guide groove  70 . At this time, the front surface of the pillar  50  is faced in a front direction and is in contact with the lower end of the first door  430  and the upper end of the second door  440 . 
     The curved part  56  of the pillar  50  is coupled to the inside to the guide groove  70 . The front surface of the pillar  50  is rotated by 90 degrees in a count-clockwise direction when compared to a state in which the first door  430  is opened and is faced in a front direction of the refrigerator  1 . 
     In this state, the elastic member  52  completely extends. When the first door  430  is withdrawn again, the pillar  50  is rotated in a clockwise direction due to the elastic restitution force of the elastic member  52 . At this time, the curved part  56  of the pillar  50  is slidingly moved along the guide groove  70 .

The freezer compartment  20  is selectively covered by a freezer compartment door  22 . 
     The refrigerator door  32  is coupled to the body  10  using a hinge  34  to cover a portion of an opened front surface of the refrigerator compartment  30  by a rotation thereof. Also, the first door  830  and the second door  840  including receiving parts  834  and  842  may be withdrawn forwardly and backwardly in a drawer-type to cover the remaining portion of the refrigerator compartment  30 . 
     The first door  830  and the second door  840  are disposed at a left side of the refrigerator compartment door  32 , and the first door  830  may be disposed above the second door  840 . A rail member  60  for slidingly guiding the withdrawal of the first door  830  is disposed on top and left side surfaces of the refrigerator compartment  30  corresponding to the first door  830 . The rail member  60  is fixed inside the refrigerator compartment  30  by a rail mounting member  70 . 
     The first door  830  may have a vertical length somewhat loner than that of the second door  840 . An ice making compartment  860  is disposed on an upper portion of a back surface of the first door  830 . The ice making compartment  860  provides a space for making and storing ice. The ice making compartment  860  receives an ice maker  452  and an ice bank  454 . 
     Since the ice making compartment  860  should be maintained at a temperature below zero to make the ice, the ice making compartment  860  may be insulated from the refrigerator compartment  30 . A dispenser  836  for dispensing water or ice is disposed at a rear side of the first door  830 . 
     In detail, the dispenser  836  is disposed at a lower portion of the ice making compartment  860 . For use s convenience, the dispenser  836  may be disposed at a middle portion or a lower portion of the first door  830  to allow a user to access the dispenser  836 . The dispenser  836  communicates with the ice making compartment  860 , and thus, may receive the made ice from the ice making compartment  860 . 
     The dispenser  836  is disposed facing the refrigerator compartment  30  to enable the dispenser  836  and the receiving part  834  to be viewed through the refrigerator compartment door  32  even through the first door  830  is closed. Also, the dispenser  836  may be exposed laterally outside the refrigerator compartment  30  when the first door  830  is slidingly withdrawn. 
     A drinking water dispensing hole, an ice dispensing hole, manipulation units of manipulating the dispensing holes, and a residual water tray are further disposed in the dispenser  836 , and a display is disposed above the dispenser  836 . 
     A receiving part  834  having multi-stages is disposed at rear and lower sides of the dispenser  836  to receive foods. 
     The second door  840  is disposed below the first door  830 . The second door  840  may be slidingly withdrawable into the refrigerator compartment  30  by a rail member  60 . 
     In detail, since the second door  840  is adjacent to an inner bottom surface and a left sidewall of the refrigerator compartment  30 , the rail member  60  and a rail mounting member  70  on which the rail member  60  is mounted are disposed on the inner bottom surface and the left sidewall of the refrigerator compartment  30 . Thus, the second door  840  may be slidingly withdrawn in a state where the second door  440  is supported by the inner bottom surface and the left sidewall of the refrigerator compartment  30 . 
     When the first door  830  and the second door  840  are closed, the receiving part  834  having the multi-states and the receiving part  842  disposed on the second door  840  are disposed on the first door  830 . Thus, foods stored in the receiving part  834  and  842  of the first door  830  and the second door  840  may be viewed through the transparent refrigerator compartment door  32  even through the refrigerator compartment door  32  is closed. 
     When the refrigerator compartment door  32  is rotated to open the refrigerator compartment  30 , the dispenser  836  is exposed to the inside of the refrigerator compartment  30 . Thus, the user may use the dispenser  836  without opening the first door  830 . 
     Vertical lengths of the first door  830  and the second door  840  may be varied as necessary. Thus, the receiving parts  834  and  842  disposed on the first door  830  and the second door  840  may be variously arranged according to the vertical lengths of the first door  830  and the second door  840 . 
     A pillar  50  is disposed at a lower end of the first door  830  to prevent cool air from leaking between the first door  830  and the second door  840  when the first door  830  and the second door  840  are closed. 
       FIG. 46  is a perspective view of a refrigerator when a door is opened, according to further another embodiment. 
     Referring to  FIG. 46 , a refrigerator of the present embodiment has the same structure as that of  FIG. 37 , except for configurations of a first door and a second door and a position of a dispenser.
