     In this embodiment, each of the sliding units  80  is configured in the three-stage rail structure to increase the maximum opening length of the freezing chamber door  41 . Alternatively, a general two-stage rail structure may be adopted, or rollers, which perform rolling motion, may be used. 
     In this embodiment, the fixed frames  70  and the sliding frames may have a structure to prevent the electric wire cable  50  from being damaged due to interference with the surroundings when the freezing chamber door  41  is inserted into and drawn from the freezing chamber  30 . 
     Each of the fixed frames  70  may extend in the frontward-and-rearward direction of the freezing chamber  30 . Each of the fixed frames  70  may be fixed to the sidewall  33  of the freezing chamber  30 . One side of a corresponding one of the fixed frames  70  may be open such that a space to receive the electric wire cable  50  is defined in the corresponding one of the fixed frames  70 . As a result, a receiving space  71  (refer to  FIG. 4 ) to receive the electric wire cable  50  drawn from the electric wire drawing part  35  may be provided between the sidewall  33  of the freezing chamber  30  and the corresponding one of the fixed frames  70 . 
     The electric wire cable  50  disposed in the receiving space  71  may extend toward the rear of the freezing chamber  30  from a part thereof coupled to the first connector  36 , may be bent, and may extent toward the front of the freezing chamber  30 . 
     In this case, a portion of the electric wire cable  50  extending toward the rear of the freezing chamber  30  may be fixedly supported by a support plane  74  formed at one side of the receiving space  71 , and the remaining portion of the electric wire cable  50  may be disposed in the receiving space  71  in a non-contact state. 
     Also, the electric wire cable  50  extending toward the front of the freezing chamber  30  may extrude from the receiving space  71  such that the electric wire cable  50  is fixedly received in an electric wire cable housing  90  coupled to a corresponding one of the sliding frame  60 . 
     That is, referring to  FIGS. 5 to 7 , the corresponding fixed frame  70  having the receiving space  71  may be provided at one side  71   a  thereof with a support plane  74  extending outward, and the support plane  74  may extend a predetermined length in a longitudinal direction L thereof from the front upper side of the receiving space  71 . 
     Also, the corresponding fixed frame  70  having the receiving space  71  may be provided at the lower part of the side  71   a  thereof with a guide hole  76  cut in the longitudinal direction L thereof such that one end of the electric wire cable housing  90  is inserted into the guide hole  76 . 
     One side of the electric wire cable housing  90  may be open such that the electric wire cable  50  is inserted into the electric wire cable housing  90 . The electric wire cable housing  90  may extend in the longitudinal direction L thereof, The electric wire cable housing  90  may detachably coupled to the lower end of a corresponding one of the sliding frames  60 . 
     The electric wire cable  50  received in the receiving space  71  may include a first length part  53  extending from the connector  51  coupled to the first connector  36  to the other end  73  of the corresponding fixed frame  70  in the longitudinal direction L thereof, a bend part  57  bent at the end of the first length part  53 , and a second length part  55  extending from the end of the bend part  57  to one end  72  of the corresponding fixed frame  70 , which is opposite to the other end  73  of the corresponding fixed frame  70 . 
     The electric wire cable  50  may be provided in the receiving space  71  of the corresponding fixed frame  70  such that the length of the electric wire cable  50  changes according to change in drawn length of the freezing chamber door  41  when the freezing chamber door  41  is drawn out. 
     That is, the electric wire cable  50  disposed in the receiving space  71  may be provided between one end  72  of the corresponding fixed frame  70  adjacent to the opening of the freezing chamber  30  and the other end  73  of the corresponding fixed frame  70  adjacent to the rear wall of the freezing chamber  30  such that the electric wire cable  50  forms a loop. 
     In this case, the first length part  53  of the electric wire cable  50  may be disposed at the upper part of the receiving space  71 , and the second length part  55  of the electric wire cable  50  may be disposed at the lower part of the receiving space  71  such that the first length part  53  and the second length part  55  are separated from each other. That is, the receiving space  71  is divided into an upper receiving space  71  and a lower receiving space  71  by the support plane  74 . 
     The front end of the first length part  53  disposed at the upper part of receiving space  71  may be located at the support plane  74  in a supported state, and the rear end of the first length part  53  may be disposed in the receiving space  71  in a freely movable state such that the shape of the rear end of the first length part  53  is deformed in correspondence to the drawn distance of the freezing chamber door  41 . 
     Meanwhile, the support plane  74  may be provided with a fixing part  75  to prevent the front end of the first length part  53  of the electric wire cable  50  located at the support place  74  in the supported state from being separated from the support place  74  when the rear end of the first length part  53  of the electric wire cable  50  is deformed. 
     The fixing part  75  may include a plurality of hooks extending from one side of the support plane  74  to surround the outer circumference of the front end of the first length part  53 . The fixing part  75  may serve to fix the front end of the first length part  53  to the support plane  74 . 
     The second length part  55  disposed at the lower part of the receiving space  71  may be received in the electric wire cable housing  90  in a supported state such that the shape of the second length part  55  is not freely deformed. 
     To this end, the electric wire cable housing  90  may be provided with a receiving part  91  open at one side thereof to receive at least a portion of the second length part  55 . The second length part  55  of the electric wire cable  50  may fixedly inserted in to the receiving part  91  through an opening of the receiving part  91  via the guide hole  76 . 
     That is, as shown in  FIG. 7 , the second length part  55  of the electric wire cable  50  is fixedly inserted into the receiving part  91  of the electric wire cable housing  90  through the opening of the receiving part  91 , and the connector  52  provided at the end of the second length part  55  protrudes from the electric wire cable housing  90  such that the connector  52  is coupled to the second connector  47  provided at the rear of the freezing chamber door  41 . 
     Consequently, the second length part  55  of the electric wire cable  50  is fixedly located in the receiving part  91 , with the result that the shape of the second length part  55  is prevented from being deformed upon insertion and drawing of the freezing chamber door  41 . 
     Meanwhile, the opening of the electric wire cable housing  90  may be disposed in the inward direction of the freezing chamber  30  to prevent the electric wire cable  50  from being exposed from the corresponding sliding frame  60  drawn together with the freezing chamber door  41 . 
     When the storage box  43  is located at the sliding frames  60 , therefore, as shown in  FIG. 12 , the opening of the electric wire cable housing  90  faces the side of the storage box  43  such that the opening of the electric wire cable housing  90  is covered by the storage box  43 . Consequently, the second length part  55  of the electric wire cable  50  is prevented from being exposed outward, thereby improving aesthetic appearance. Also, a connector cover  58  may be mounted at the rear of the freezing chamber door  41  to prevent the connector  52  and the second length part  55  protruding from the electric wire cable housing  90  from being exposed outward. 
     The electric wire cable housing  90  may prevent the electric wire cable  50  from being exposed upon drawing of the freezing chamber door  41  and guide the electric wire cable  50  such that the electric wire cable  50  is arranged at the original position in the receiving space  71  upon insertion of the freezing chamber door  41 . 
     The electric wire cable housing  90  may be integrally or detachably provided at the lower part of the corresponding sliding frame  60  such that the electric wire cable housing  90  moves simultaneously with the corresponding sliding frame  60  upon movement of the corresponding sliding frame  60 . 
     In this case, the electric wire cable housing  90  may be disposed such that the electric wire cable housing  90  faces the guide hole  76  formed at the corresponding fixed frame  70 , and the end of the electric wire cable housing  90  adjacent to the bent part  57  of the electric wire cable  50  may be provided with a guide part  93  configured to be movable along the guide hole  76 . 
     The guide part  93  may be bent and extend from the end of the electric wire cable housing  90  toward the guide hole  76  such that the guide part  93  is inserted into the guide hole  76 . The guide part  93  bent and extending toward the guide hole  76  serves to guide the electric wire cable  50  such that the electric wire cable  50  is deformed and moved only in the receiving space  71 . 
     In this embodiment, interference between the electric wire cable  50  and the surroundings is avoided, when the freezing chamber door  41  is drawn out and inserted into the freezing chamber  30 , thereby preventing damage to the electric wire cable  50 . That is, when the freezing chamber door  41  is drawn out, as shown in  FIG. 8 , the corresponding sliding frame  60  fixed to the freezing chamber door  41  and the electric wire cable housing  90  fixed to the corresponding sliding frame  60  are also slid and drawn frontward. 
     In this embodiment, the second length part  55  of the electric wire cable  50  connected to the second connector  47  provided at the rear of the freezing chamber door  41  is pulled frontward, with the result that the first length part  53  of the electric wire cable  50  disposed at the rear of the receiving space  71  such that the first length part  53  is not fixed to the corresponding fixed frame  70  but freely deformed is moved frontward while being deformed by a drawn length thereof. 
     That is, the front end of the first length part  53  of the electric wire cable  50  located at the support plane  74  is fixed by the fixing part  75 , with the result that the front end of the first length part  53  of the electric wire cable  50  does not move upon drawing of the freezing chamber door  41 . However, the rear end (imaginary part) of the first length part  53  of the electric wire cable  50  disposed at the rear of the support plane  74  is deformed by the drawn distance of the freezing chamber door  41  and moved in the longitudinal direction L thereof upon drawing of the freezing chamber door  41 . 
     At this time, the second length part  55  of the electric wire cable  50  drawn frontward is received in the electric wire cable housing  90 , and therefore, the second length part  55  is not exposed to the outside, and, at the same time, damage to the second length part  55  due to interference with a surrounding structure is prevented. 
     Also, when the freezing chamber door  41  is inserted into the freezing chamber  30 , the electric wire cable housing  90  guides the electric wire cable  50  disposed in the receiving space  71  according to a predetermined motion pattern such that the electric wire cable  50  is moved to the original position (shown by an imaginary line) in the receiving space  71 . 
     In this embodiment, the deforming portion of the electric wire cable  50  is guided by the guide part  93  such that the deforming portion of the electric wire cable  50  is moved in the receiving space  71  from the end of the electric wire cable housing  90  toward the inside of the receiving space  71 . 
     Meanwhile, during the deformation of the electric wire cable  50  disposed in the receiving space  71  upon drawing and insertion of the freezing chamber door  41 , as shown in  FIG. 10 , the electric wire cable  50  may protrude out of the guide hole  76 , with the result that the electric wire cable  50  may be bent or damaged due to interference with the surroundings. 
     To prevent the electric wire cable  50  from being bent or damaged, the corresponding sliding frame  60  may be provided at the lower part of the rear end thereof with a push member  63 . 
     As shown in  FIG. 11 , the push member  63  may press the electric wire cable  50  protruding out of the guide hole  76  to push the protruding portion of the electric wire cable  50  in a contact state into the receiving space  71  inside the guide hole  76 . 
     To this end, the push member  63  may include a fixing part  64  fixed to the corresponding sliding frame  60 , a tight contact part  65  extending from the fixing part  64  such that the tight contact part  65  tightly contacts the guide hole  76 , and a pressing part  66  provided at one end of the tight contact part  65  to contact the electric wire cable  50  protruding out of the guide hole  76 . 
     The tight contact part  65  may be disposed adjacent to the guide hole  76  such that the tight contact part  65  faces the guide part  93  of the electric wire cable housing  90 . 
     The pressing part  66  presses the electric wire cable  50  protruding out of the guide hole  76  to guide the protruding portion of the electric wire cable  50  into the receiving space  71 . The pressing part  66  may be bent to prevent damage to the electric wire cable  50  due to contact. 
     Meanwhile, in this embodiment, the refrigerator may further include an opening and closing detection unit  95  and  96  to detect an open or closed state of the freezing chamber door  41 . 
       FIG. 13  is a view illustrating an opening and closing detection unit according to an embodiment. Referring to  FIG. 13 , the opening and closing detection unit  95  and  96  may include a reed switch  95  disposed at the front end of the receiving space  71  of the corresponding fixed frame  70  and a magnet  96  disposed at the front of the lower end of the corresponding sliding frame  60 . 
     The front end of the corresponding fixed frame  70  may be provided with an open switch hole  98 , through which the reed switch  95  is exposed, and the reed switch  95  may be disposed in the receiving space  71  inside the switch hole  98 . 
     Also, the reed switch  95  may be electrically connected to an electric wire  99  drawn from the electric wire drawing part  35  provided in the vicinity of the front end of the corresponding sidewall  33  of the freezing chamber  30 . The reed switch  95  is connected to a controller (not shown) to transmit and receive an operation signal to and from the controller. 
     That is, when the freezing chamber door  41  is drawn with the result that the magnet  96  provided at the corresponding sliding frame  60  is placed in the vicinity of the reed switch  95 , the reed switch  95  is operated, and the operation signal of the reed switch  95  is output to the controller. 
     The open or closed state of the freezing chamber door  41  is detected by the cooperation of the reed switch  95  and the magnet  96 . The reed switch  95  is disposed adjacent to the electric wire drawing part  35 , thereby reducing the length of the electric wire  99 . Meanwhile, the electric wire  99  connected to the reed switch  95  is separately provided as shown in  FIG. 13 . Alternatively, the reed switch  95  may be electrically connected to the electric wire cable  50 , which is connected to the control panel  45 . 
     As is apparent from the above description, the electric wire cable connected to the control panel is prevented from being damaged upon sliding insertion and drawing of the freezing chamber door in the frontward-and-rearward direction of the refrigerator body, thereby improving reliability of the refrigerator. 
     Although a few embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
