CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of priority to Korean Application No. 10-2009-0049003, filed on Jun. 3, 2009, which is hereby expressly incorporated by reference in its entirely. 
       FIELD 
       [0002]    The present disclosure relates to a refrigerator. 
       BACKGROUND 
       [0003]    In general, a refrigerator uses cold air produced as refrigerant vaporizes and absorbs heat from the air. 
         [0004]    In detail, the refrigerant is compressed at a compressor, and forwarded to an evaporator via an expansion valve, where the refrigerant vaporizes. The refrigerant absorbs heat from surroundings in such a vaporizing process, and cools down surrounding air to produce the cold air. 
         [0005]    The cold air is forwarded to the refrigerating chamber or the freezing chamber for maintaining the refrigerating chamber or the freezing chamber to be below a fixed temperature. 
         [0006]    Depending on arrangement of the refrigerating chamber or the freezing chamber, in the refrigerators, there are a top mount-type refrigerator in which the freezing chamber is arranged on the refrigerating chamber, a bottom freezer type refrigerator in which the freezing chamber is arranged under the refrigerating chamber, and a side by side type refrigerator in which the refrigerating chamber and the freezing chamber are arranged side by side. Above categorization is just for convenience&#39;s sake, but not absolute ones. 
         [0007]    The bottom freezer type refrigerator has an inside space partitioned with a barrier, an upper side of which is the refrigerating chamber and a lower side of which is the freezing chamber. 
         [0008]    In general, the refrigerating chamber has at least one refrigerating chamber door rotatably mounted thereto to open/close the refrigerating chamber, and the freezing chamber has a drawer structure which is slidably moved back and forth to open/close the freezing chamber. 
         [0009]    In general, in rear of the freezing chamber and the refrigerating chamber, there are the evaporators and fans for blowing the cold air respectively, for generating the cold air individually to control temperatures of the freezing chamber and the refrigerating chamber, respectively.

     DETAILED DESCRIPTION 
       [0024]    Reference will now be made in detail to the specific implementations of the present technology, examples of which are illustrated in the accompanying drawings  FIGS. 1 to 5 . Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. 
         [0025]    A refrigerator shown in  FIG. 1  is a side by side door type refrigerator, wherein a freezing chamber  10  is on a left side and a refrigerating chamber  20  is on a right side. 
         [0026]    The refrigerating chamber  20  and the freezing chamber  10  are opened/closed by a refrigerating chamber door  21  and a freezing chamber door  11 , respectively. In inside walls of the refrigerating chamber door  21  and the freezing chamber door  11 , there are shelves and so on for storage, respectively. And, there are an ice maker mounted to the freezing chamber door  11  and a home bar mounted to the refrigerating chamber door  21 . 
         [0027]    Mounted in spaces of the refrigerating chamber and the freezing chamber  10 , there are storage structures  30  and  40 , respectively. The storage structures and  40  are mounted to be movable in front/rear directions in the refrigerating chamber  20  and the freezing chamber  10 . 
         [0028]    Since it is required to secure spaces for placing the ice maker or the home bar therein at the time the refrigerating chamber door  21  and the freezing chamber door  11  are closing, front/rear direction depths of the storage structures  30  and  40  can be determined, taking the spaces to be secured into account. 
         [0029]    Each of the storage spaces  30  and  40  includes an inner frame  43  and a plurality of shelves and drawers arranged vertically in the inner frame  43 , as shown in  FIG. 2 .  FIG. 1  illustrates a perspective view showing the storage structures  30  and  40  moved forward. 
         [0030]    The storage structure will be described in detail with reference to the storage structure  40  mounted in the refrigerating chamber  20 . 
         [0031]    Referring to  FIG. 2 , the inner frame  43  includes one pair of vertical supporting frames  44 , a top frame  45  extended from a top edge of the supporting frames  44  perpendicular thereto, and a bottom frame  46  extended from a bottom edge of the supporting frames  44  perpendicular thereto. 
         [0032]    There are a plurality of shelves  41  arranged in a vertical direction in the one pair of the supporting frames  44 , and a drawer unit  42  having a plurality of drawers provided therein under the shelves  41 . 
         [0033]    As a variation, a plurality of drawers can be provided and mounted to the inner frame  43 , individually. 
         [0034]    The inner frame  43  is housed in the refrigerating chamber  20 . Though the inner frame  43  has a height as high as the refrigerating chamber  20 , as a variation, the inner frame  43  can be fabricated to have a height lower than the refrigerating chamber  20 . That is, the inner frame  43  can be fabricated to have a height to occupy a portion of the refrigerating chamber  20  space, such as an upper space thereof or a lower space thereof. 
         [0035]    Referring to  FIG. 4 , the inner frame  43  is mounted to be slidable along wall surfaces of the refrigerating chamber  20  in front/rear directions. 
         [0036]      FIGS. 4 and 5  illustrate perspective views each showing the inner frame  43  mounted such that a top surface and a bottom surface of the inner frame  43  are slidable with respect to a ceiling surface and a bottom surface of the refrigerating chamber  20 , respectively. 
         [0037]    In detail, the refrigerating chamber  20  has a top sliding guide  72  mounted to the ceiling surface thereof and the inner frame  43  has a top slider  71  mounted to the top surface thereof slidably connected to the top sliding guide  72 . The top slider  71  and the top frame  45  of the inner frame  43  together form a top sliding unit. 
         [0038]    The refrigerating chamber  20  has a bottom slider  82  mounted on a bottom surface, and to match with this, the inner frame  43  has a bottom slider  81  mounted to a bottom surface of the inner frame  43 . The bottom slider  81  and the bottom frame  46  together form a bottom sliding unit. 
         [0039]    Owing to above sliding structure, the inner frame  43  can slide in the refrigerating chamber  20  in front/rear directions. 
         [0040]    In the meantime, there are link devices  60  and  65  mounted to the refrigerator for making the inner frame  43  to be movable in front/rear directions interlocked to the opening/closing of the refrigerating chamber door  21 . 
         [0041]    The link device includes a first link  61  or  66  rotatably connected to the inner frame  43 , and a second link  62  or  67  rotatably connected to the refrigerating chamber door  21 . 
         [0042]    The link devices  60  and  65  are mounted to a top and a bottom respectively, wherein the top first link  61  and the top second link  62  are mounted to the top, and the bottom first link  66  and the bottom second link  67  are mounted to the bottom. 
         [0043]    There can be another means for interlocking the opening/closing of the refrigerating door  21  with the sliding of the inner frame  43 . For an example, a rack gear can be provided to the inner frame  43 , and a motor can be connected to the rack gear through a gear. Accordingly, the motor is made to operate as the door  21  opens, to make the inner frame  43  to slide forward. 
         [0044]    In a state the refrigerating door  21  is closed, the refrigerator has the inner frame  43  positioned on a rear side of the refrigerating chamber  20 , and the home bar and the shelves mounted in the inside wall of the refrigerating chamber door  21  positioned in a front side space of the refrigerating chamber  20 .  FIG. 3  illustrates a perspective view showing arrangement of the inner frame  43  and the refrigerating chamber door  21  in a state the refrigerating chamber door  21  is closed. 
         [0045]    In this state, if the refrigerating chamber door  21  is opened, the inner frame  43  slides forward interlocked with the opening of the refrigerating chamber door  21 .  FIG. 1  illustrates a perspective view showing a state the inner frame  43  is drawn out to a front side in a state the refrigerating chamber door  21  is opened, fully. 
         [0046]    In some examples, the inner frame is moved in forward and backward directions in connection with opening and closing the refrigerating chamber door  21 . In the opening operation, after the refrigerating chamber door  21  is opened to open the refrigerating chamber  20  or while the refrigerating chamber door  21  is being opened, the motor provides a driving force to the rack gear to move the closing motor in the forward or front direction. In the closing state, before the refrigerating chamber door  21  is closed to close the refrigerating chamber  20  or while the refrigerating chamber door  21  is being closed, the motor provides a driving force to the rack gear to move the inner frame in the backward or rear direction. 
         [0047]    In some examples, configuration of the inner frame  43  can be modified. For example, a plurality of the inner frames could be mounted in the refrigerating chamber  20 . If the refrigerator has two inner frames, as an example, an upper inner frame may have a height that corresponds to that of the home bar, and a lower inner frame may have a height that corresponds to that of the baskets location. That is, as shown in  FIG. 3 , the refrigerating chamber door  21  may divide two doors, which are a home bar door  22  and a basket door  23 . In this implementation, a user may independently open and close the home bar door  22  and the basket door  23 . When the user opens the home bar door  22 , the upper inner frame and a corresponded structure (e.g., a plurality of shelves or draws) that is mounted in the upper inner frame move in the forward direction of the refrigerator, and when the user closes the home bar door  22 , the upper inner frame and the corresponded structure move in the backward direction of the refrigerator. Likewise, when the user opens the bracket door  23 , the lower inner frame and a corresponded structure that is coupled to the bracket door move in the forward direction of the refrigerator, and when the user closes the bracket door  23 , the lower inner frame and the corresponded structure move in the backward direction of the refrigerator. 
         [0048]    Further, in the above implementation, when the user opens the refrigerating chamber door  21 , the inner frame  43  and the corresponded structure  40  as shown in  FIGS. 4 and 5  move in the forward direction of the refrigerator, and when the user closes the refrigerating chamber door  21 , the inner frame  43  and the corresponded structure move  40  in the backward direction of the refrigerator. In this case, the home bar door  22  and the basket door  23  may be a part of the refrigerating chamber door  21 . Also, moving structure or structure in connection with the home bar door  22  may be a part of the moving structure  40 . Further, moving structure in connection with the basket door  23  may be a part of the moving structure  40 . 
         [0049]    As a moving structure (i.e., a part of storage chamber) may be moved in connection with movement of a door, various modifications are possible. For example, two moving members are moved in connection with opening and closing the refrigerating chamber door  21  and the home bar door  22 , respectively. Alternatively, two moving members are moved in connection with opening and closing opening and closing the refrigerating chamber door  21  and the basket door  23 , respectively. The moving members may include the inner frame and corresponded structure or components. 
         [0050]    As an example, the home bar door  22  is a part of the refrigerating chamber door  21 . So, the moving member moved in connection with the home bar door may be a part of the moving member moved in connection with the refrigerating chamber door  21 . 
         [0051]    It is also available that a plurality of moving members in a refrigerators that are independently moved in connection with opening and closing of three or more than three doors. 
         [0052]    Since moving member or members are moved in the forward and backward directions, the refrigerator may need a protector to prevent the refrigerator from falling down. For example, when the moving structure  40  moves in the forward direction of the refrigerator, a lot of stuffs contained in the storage chamber also move in the forward direction. Therefore, it may cause to fall the refrigerator down because a relatively heavy weight was shifted to the front or forward side within a short period. To avoid falling down, the refrigerator may keep contacting or connecting an adjacent thing, such as a wall, when the moving structure  30  or  40  moves in the forward direction. In this implementation, an end of protector (e.g., a string) is connected to the refrigerator and the other end of the protector is connected to the wall such that the refrigerator can&#39;t be moved away from the wall. 
         [0053]    As has been described, since the storage structure mounted in the storage chamber can be movable in front/rear directions, drawing out/pushing in of a storage object becomes more convenient. 
         [0054]    It will be understood that various modifications may be made without departing from the spirit and scope of the claims. For example, advantageous results still could be achieved if steps of the disclosed techniques were performed in a different order and/or if components in the disclosed systems were combined in a different manner and/or replaced or supplemented by other components. Accordingly, other implementations are within the scope of the following claims.
