Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation of U.S. patent application Ser. No. 13/799,258, filed on Mar. 13, 2013, which claims the benefit of Korean Patent Application No. 10-2012-0027185, filed on Mar. 16, 2012, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference. 
     
    
     BACKGROUND 
       [0002]    1. Field 
         [0003]    Embodiments of the present disclosure relate to a refrigerator having a rotating bar configured to seal a gap formed between a pair of doors thereof. 
         [0004]    2. Description of the Related Art 
         [0005]    In general, a refrigerator is a household appliance having a storage compartment to store food, and a cool air supplying apparatus to supply cool air to the storage compartment to store the food in a fresh manner. The refrigerator, according to the storage compartment and a door thereof, may be classified into different types. 
         [0006]    A TMF (Top Mounted Freezer)-type refrigerator is provided therein with a storage compartment that is divided into an upper side and a lower side by a horizontal partition while a freezing compartment is formed at the upper side and a refrigerating compartment is formed at the lower side, and a BMF (Bottom Mounted Freezer)-type refrigerator is provided with a refrigerating compartment formed at the upper side while a freezing compartment is formed at the lower side. 
         [0007]    In addition, a SBS (Side By Side)-type refrigerator is provided therein with a storage compartment that is divided into an left side and a right side by a vertical partition while a freezing compartment is formed at one side and a refrigerating compartment is formed at the other side, and a FDR (French Door Refrigerator)-type refrigerator is provided therein with a storage compartment that is divided into an upper side and a lower side by a horizontal partition while a refrigerating compartment is formed at the upper side and a freezing compartment is formed at the lower side, as the refrigerating compartment at the upper side is open/closed by a pair of doors. 
         [0008]    Meanwhile, a gasket is provided at a door of a refrigerator to seal a gap which is formed between the door and the body of the refrigerator when the door is closed. However, with respect to the FDR-type refrigerator, the refrigerating compartment at the upper side is open and closed by a pair of doors, but the refrigerating compartment is not provided therein with a vertical partition, and thus a gap formed between the pair of doors may not be sealed by the gasket. In order to seal the gap between the pair of doors, a rotating bar rotatably installed at one of the pair of the doors is suggested. 
         [0009]    The rotating bar as such, when the pair of doors is closed, is being rotated in a horizontal state with respect to the pair of doors to seal the gap in between the pair of doors, and when one door provided with the rotating bar installed thereto is open, the rotating bar is being rotated to a vertical state with respect to the other door, so that the rotating bar is not being interfered at the other door, which is not provided with the rotating bar installed thereto. 
         [0010]    Meanwhile, the rotating bar includes a heat insulation member configured to block cool air from being discharged from a storage compartment, a metal plate formed of metal so as to come into close contact with a gasket installed at a rear surface of the door, and a heat generating member configured to radiate heat to prevent the frost from being formed at the plate. 
       SUMMARY 
       [0011]    Therefore, it is an aspect of the present disclosure to provide a structure of a rotating bar having an enhanced insulation performance. 
         [0012]    It is another aspect of the present disclosure to provide a structure of a rotating bar enabling an insertion protrusion of the rotating bar to be inserted into a guide part regardless of the position of the rotating bar. 
         [0013]    It is still another aspect of the present disclosure to provide a structure of a rotating bar capable of sealing a gap between the rotating bar and a body as well as a gap between one pair of doors. 
         [0014]    Additional aspects of the disclosure will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the disclosure. 
         [0015]    In accordance with one aspect of the present disclosure, a refrigerator includes a body, a storage compartment, a first door, a second door, a first gasket, a second gasket, a rotating bar and a guide part. The storage compartment may be formed at an inside of the body while having a front surface thereof open. The first door may be configured to open/close a portion of the front surface of the storage compartment that is open. The second door may be configured to open/close a remaining portion of the front surface of the storage compartment that is open. The first gasket may be installed at a rear surface of the first door to seal a gap formed between the first door and the body. The second gasket may be installed at a rear surface of the second door to seal a gap formed between the second door and the body. The rotating bar may be rotatably coupled to the first door to seal a gap formed between the first door and the second door in a state that the first door and the second door are closed. The guide part may be provided at the body to guide a rotation of the rotating bar, and may have a guide body part fixed to the body and a guide groove formed in the guide body part. The rotating bar may include a case, a heat insulation member, a metallic plate, a heat generating member, and an insertion protrusion. The case may be provided with an accommodating space therein. The heat insulation member may be accommodated in the accommodating space. The metallic plate may be coupled to the case. The heat generating member may be configured to prevent frost from being formed on the metallic plate. The insertion protrusion may be configured to be elastically biased toward an outer side of the case so as to be inserted into the guide groove, and upon exertion of external force, may be configured to move toward an inner side of the case. 
         [0016]    If the first door is closed in a state of the rotating bar being rotated in perpendicular to the first door, the insertion protrusion may enter the guide groove through an entry of the guide groove and then may be rotated along a curved surface of the guide groove. If the first door is closed in a state of the rotating bar being rotated in parallel to the first door, the insertion protrusion may move toward the inner side of the case by the external force of the guide body part to avoid an interference with the guide body part, and then may move toward the outer side of the case by the elastic force so as to be inserted into the guide groove. 
         [0017]    The insertion protrusion may include a protrusion part, an elastic member, and a stopper part. The protrusion part may be configured to be inserted into the guide groove. The elastic member may be configured to elastically support the protrusion part such that the protrusion part protrudes toward the outer side of the case. The stopper part may be configured to prevent the protrusion part from being separated to an outside the case. 
         [0018]    The protrusion part may include an inclined surface. The inclined surface may be configured to allow the protrusion part to perform a vertical movement by a horizontal force exerted on the protrusion part. 
         [0019]    The insertion protrusion may be provided on at least one of an upper end and a lower end of the rotating bar. 
         [0020]    The case may be provided with a passage part provided in a form of a hole that allows the insertion protrusion to pass therethrough. 
         [0021]    A support part configured to support the elastic member may be provided at the inner side of the case. 
         [0022]    The rotating bar may further include a sealing member. The sealing member may have a blocking wall that protrudes to the outer side of the case so as to seal a gap formed between the body and the rotating bar. 
         [0023]    The sealing member may be formed of rubber. 
         [0024]    In accordance with another aspect of the present disclosure, a refrigerator includes a body, a storage compartment, a pair of doors, a rotating bar, and a sealing member. The storage compartment may be formed at an inside of the body while having a front surface thereof open. The pair of doors may be rotatably coupled to the body to open/close the front surface of the storage compartment that is open. The rotating bar may be rotatably coupled to one of the pair of doors to seal a gap formed between the pair of doors in a state that the pair of doors are closed. The sealing member may protrude from the rotating bar to seal a gap formed between the rotating bar and the body. 
         [0025]    The refrigerator may further include a guide part and an insertion protrusion. The guide part may be provided at an upper side of the body to guide a rotation of the rotating bar. The insertion protrusion may protrude toward an upper side from the rotating bar so as to be rotated while being inserted into the guide part. The insertion protrusion may be provided so as to enable a vertical movement. 
         [0026]    The refrigerator may further include an elastic member. The elastic member may be configured to elastically support the insertion protrusion to the upper side. 
         [0027]    The insertion protrusion may include an inclined surface that allows the insertion protrusion to move to a lower side by a pressing force exerted in a horizontal direction. 
         [0028]    As described above, with respect to the rotating bar for sealing a gap between one pair of doors, the doors are prevented from being incompletely closed due to an erroneous operation of the rotating bar, and the convenience of use is improved. 
         [0029]    In addition, the rotating bar seals a gap between the rotating bar and the door as well as a gap between one pair of doors, thereby improving the heat insulation efficiency of the storage compartment.

     DETAILED DESCRIPTION 
       [0039]    Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. 
         [0040]      FIG. 1  is a drawing illustrating a front of a refrigerator in accordance with one aspect of the present disclosure. Referring to  FIG. 1 , a refrigerator  1  in accordance with one embodiment of the present disclosure includes a body  10 , storage compartments  20  and  30  divided into an upper side and a lower side at an inside the body  10 , doors  31 ,  40 , and  50  configured to open/close the storage compartments  20  and  30 , and a cool air supplying apparatus (not shown) to supply cool air to the storage compartments  20  and  30 . 
         [0041]    The body  10  may include an inner case forming the storage compartments  20  and  30 , an outer case forming an exterior appearance by being coupled to an outer side of the inner case, and a heat insulation member foamed in between the inner case and the outer case and configured to thermally insulate the storage compartments  20  and  30  from each other. 
         [0042]    The cool air supplying apparatus (not shown) may generate cool air by using a cooling circulation cycle configured to compress, condense, expand, and evaporate refrigerant. 
         [0043]    The storage compartments  20  and  30  may be provided with a front surface thereof open, and may be partitioned into the refrigerating compartment  20  at the upper side and the freezing compartment  30  at the lower side. The refrigerating compartment  20  may be open and closed by a pair of doors  40  and  50  that are rotatably coupled to the body  10 , and the freezing compartment  30  may be open and closed by a sliding door  31  slidably mounted at the body  10 . 
         [0044]    The pair of doors  40  and  50  configured to open and close the refrigerating compartment  20  may be disposed side by side. Hereinafter, for the sake of convenience, the left side door  40  on the drawing is referred to as the first door  40  and the right side door  50  on the drawing is referred to as the second door  50 . 
         [0045]    The first door  40  is configured to open and close a left portion of the front surface of the refrigerating compartment  20  that is open, and the second door  50  is configured to open and close the remaining portion of the front surface of the refrigerating compartment  20  that is open. Door shelves  41  and  51  are provided at the rear surfaces of the first door  40  and the second door  50 , respectively, to store foods. In addition, at the rims of the rear surfaces of the first door  40  and the second door  50 , gaskets  42  and  52  are provided, respectively, to seal the gap with respect to the body  10  in a state that the first door  40  and the second door  50  are closed. 
         [0046]    The gaskets  42  and  52  may be installed in a shape of a loop along the rims of the rear surfaces of the first door  40  and the second door  50 , respectively, and magnets ( 42   a  and  52   a  in  FIGS. 4 and 5 ) may be included at an inside the gaskets  42  and  52 , respectively. 
         [0047]    Meanwhile, in a state that the first door  40  and the second door  50  are closed, a gap may be formed between the first door  40  and the second door  50 , and in order to seal the gap as such, a rotating bar  100  is rotatably mounted at the first door  40 . 
         [0048]    The rotating bar  100  as such is provided in a bar shape formed lengthwise along the height direction of the first door  40 , and may be rotated by a guide part  60  provided at the body  10 . The guide part  60  of the body  10  may include a guide body ( 61  in  FIG. 6 ) coupled to the body  10 , and a guide groove ( 62  in  FIG. 6 ) formed at the guide body  61 . Hereinafter, the structure and the operation of the rotating bar  100  as such will be described. 
         [0049]      FIG. 2  is an exploded perspective view showing a structure of the rotating bar of the refrigerator of  FIG. 1 ,  FIG. 3  is an assembled perspective view of the rotating bar of the refrigerator of  FIG. 1 , and  FIG. 4  is a cross-sectional view of the rotating bar of the refrigerator of  FIG. 1 . 
         [0050]    Referring to  FIGS. 2 to 4 , the rotating bar  100  includes a case  110  having an accommodating space  110   a  and provided with one surface thereof open, a heat insulation member  120  accommodated in the accommodating space  110   a  of the case  110 , a cover  130  coupled to the one open surface of the case  110 , a metallic plate  150  coupled to an outer side of the cover  130 , and a heat generating member  140  disposed at a space in between the cover  130  and the metallic plate  150 . 
         [0051]    The case  110  is configured to form an external appearance of the rotating bar  100 , and may be provided at an inside thereof with the accommodating space  110   a  having one surface open, and the one open surface of the rotating bar  100  may be covered by the cover  130 . A hinge bracket coupling part  110   b  to which a hinge bracket ( 70  in  FIG. 6 ) is coupled may be provided at the case  110 . 
         [0052]    The hinge bracket  70  may include a fixing part ( 71  in  FIG. 6 ) fixed to the rear surface of the first door  40 , and a hinge bar ( 72  in  FIG. 6 ) configured to connect the fixing part  71  to the rotating bar  100 , so that the rotating bar  100  is rotated on a rotation shaft ( 73  in  FIG. 6 ). The fixing part  71  may be coupled to the rear surface of the first door  40  by use of a connecting member such as a screw. 
         [0053]    In addition, at an upper surface of the case  110 , a passage part  112  may be provided, so that an insertion protrusion  161  being inserted into the guide groove ( 62  in  FIG. 6 ) of the guide part ( 60  in  FIG. 6 ) may be protruded to an outside the case  110 . The passage part  112  may be provided in the form of a hole having the same shape as the insertion protrusion  161 . 
         [0054]    In the embodiment of the present disclosure, the guide part  60  is formed at an upper portion of the body  10  while the insertion protrusion  161  is protruded toward an upper side of the rotating bar  100 . However, the guide part  60  may be formed at a lower portion of the body  10  while the insertion protrusion  161  may be protruded toward a lower side of the rotating bar  100 . In this case, the passage part  112  of the case  110  may also be formed at a lower surface of the case  110 . The case  110  as such may be injection-molded using plastic material as an integrated body. 
         [0055]    The heat insulation member  120  is configured to thermally insulate the refrigerating compartment  20 , and may be formed of EPS (Expanded PolyStyrene) material having superior insulation performance and light weight. The heat insulation member  120 , after being formed in an approximate shape to be inserted into the accommodating space  110   a  of the case  110 , may be inserted into the accommodating space  110   a  of the case  110 . 
         [0056]    The cover  130  is configured to cover the one surface of the case  110  that is open, and may be coupled to the one open surface of the case  110  after the heat insulation member  120  is inserted into the accommodating space  110   a  of the case  110 . 
         [0057]    As illustrated on  FIG. 4 , the cover  130  is provided with a cross section obtained by being bent several times, and forms a portion of the side surface and a portion of the rear surface of the rotating bar  100 . Here, the rear surface of the rotating bar  100  is referred to as a surface facing the gaskets  42  and  52  of the doors  41  and  51 . 
         [0058]    In detail, the cover  130  includes a heat insulation member adhering part  131  making contact with the heat insulation member  120 , a second coupling part  132  to which the metallic plate  150 , which will be described later, is coupled, a heat conduction blocking part  133  protruded toward the metallic plate  150 , and a side surface forming part  134  forming at least one portion of the side surface of the rotating bar  100 . The cover  130  may be injection molded using plastic material having low heat conductivity as an integrated body. 
         [0059]    The metallic plate  150  may be coupled to an outer side of the cover  130  as such, and the metallic plate  150  is formed of metallic material so as to come into close contact with the gaskets  42  and  52  by the magnetic force of the magnets  42   a  and  52   a  included in the gaskets  42  and  52 , and to provide rigidity to the rotating bar  100 . 
         [0060]    The metallic plate  150  may include a first coupling part  151  being coupled to the second coupling part  132  of the cover  130 , and a gasket close-contact part  152  coming into close contact with the gaskets  42  and  52 . The first coupling part  151  of the metallic plate  150  is coupled to the second coupling part  132  of the cover  130  by a connecting member such as a screw or by an adhesive member. 
         [0061]    Meanwhile, the heat generating member  140 , which is configured to generate heat to prevent frost from being formed on the metallic plate  150  due to the temperature difference between the inside and the outside the refrigerating compartment  40 , may be disposed at a space formed by the first coupling part  151  of the metallic plate  150  and the gasket close-contact part  152  of the metallic plate  150 . 
         [0062]    Here, so as to prevent the heat generated from the heat generating member  140  from being excessively delivered to the metallic plate  150 , the heat generating member  140  may be implemented by a heating cable  140 , which includes a heating wire covered with non-conductive material such as silicon or an FEP (Fluorinated Ethylene Propylene). 
         [0063]    Thus, the heat generating member  140 , so as to deliver the minimum amount of heat to the metallic plate  150  to prevent frost from being formed on the metallic plate  150 , may be disposed in a line-contacted manner with the metallic plate  150  instead of being surface-contacted with the metallic plate  150 . 
         [0064]    Meanwhile, the heat conduction blocking part  133  of the cover  130  and the gasket close-contact part  152  of the metallic plate  150 , both of which were previously described, form the rear surface of the rotating bar  100 . The central portion of the rear surface of the rotating bar  100  is formed by the gasket close-contact part  152  of the metallic plate  150 , and both side edge portions of the rear surface of the rotating bar  100  are formed by the heat conduction blocking part  133  of the cover  130 . 
         [0065]    In order to prevent the heat, which is being conducted along the gasket close-contact part  152  of the metallic plate  150 , from being conducted to the side surface of the rotating bar  100 , the heat conduction blocking part  133  of the cover  130  is needed to be provided for a predetermined length L. 
         [0066]    The length L of the heat conduction blocking part  133  of the cover  130  is provided to be approximately larger than a thickness D of the cover  130 , and within the limit that the metallic plate  150  comes into close contact with the gaskets  42  and  52  by the magnetic force of the magnets  42   a  and  52   a  that are included in the gaskets  42  and  52 , the length of the gasket close-contact part  152  of the metallic plate  150  may be reduced while increasing the length L of the heat conduction blocking part  133  of the cover  130 . 
         [0067]    According to the structure as the above, in a state where the first door  40  and the second door  50  are closed, the rotating bar  100  may seal the gap between the first door  40  and the second door  50  while coming into close contact with the gaskets  42  and  52  of the first door  40  and the second door  50 , and may also minimize the heat, which is generated from the heat generating member  140  of the rotating bar  100 , from penetrating to an inside the refrigerating compartment  20 . 
         [0068]    Thus, the insulation performance of the rotating bar  100  is enhanced while the heat loss of the heat generating member  140  is minimized, thereby able to save the energy needed to prevent frost from being formed on the rotating bar  100 . 
         [0069]    Meanwhile, sealing members ( 170  and  180  in  FIG. 2 ) may be provided at an upper end and at a lower end of the rotating bar  100 , respectively, to seal a gap formed between the rotating bar  100  and the body  10  in a state that the doors  40  and  50  are closed. 
         [0070]    The sealing member  170  of the upper end and the sealing member  180  of the lower end may include blocking walls  171  and  181 , respectively, which protrude to seal the gap in between the guide part  60  of the body  10  and the rotating bar  100  in a state that the door  40  is closed. 
         [0071]    As illustrated in one embodiment shown in  FIG. 12  of the present disclosure, in a case when the guide part  60  is provided at an upper portion of the body  10 , the sealing member  170  may seal the gap between the guide part  60  and the rotating bar  100 . 
         [0072]    The sealing members  170  and  180  as such may be formed of flexible material such as rubber to seal the gap between the body  10  and the rotating bar  100  in a smooth manner without damage by a collision. 
         [0073]      FIG. 5  is a cross-sectional view of a rotating bar of a refrigerator in accordance with another aspect of the present disclosure. Hereinafter, the structure of a rotating bar in accordance with another embodiment of the present disclosure will be described with reference to  FIG. 5 . In the following description, the same reference numerals will be assigned to the parts of the present embodiment that are identical to those according to the previous embodiment, and details of parts will be omitted in order to avoid redundancy. 
         [0074]    In accordance with another embodiment of the present disclosure, the rotating bar  100  includes a case  110  provided with an accommodating space formed at an inside thereof and having one surface thereof open, a heat insulation member  120  accommodated in the accommodating space of the case  110 , a metallic plate  150  coupled to the one open surface of the case  110 , a heat generating member  140  configured to radiate heat to prevent frost from being formed on the metallic plate  150 , and a heat insulation film  190  formed on a surface of the metallic plate  150  that is exposed to the outside. 
         [0075]    The heat insulation film  190  is configured to increase the heat resistance of the metallic plate  150  so as to prevent the heat generated at the heat generating member  140  from penetrating to the refrigerating compartment  20  after being delivered along the metallic plate  150  to the both side surfaces of the rotating bar, and the heat insulation film  190  may be formed of material having a low heat conductivity. 
         [0076]    The heat insulation film  190  may be formed on the surface of the metallic plate  150  through a method such as a coating, or may be formed by attaching processed material having a shape of a thin panel to the metallic plate  150 . 
         [0077]    However, the heat insulation film  190  is needed to be provided with a thickness less than a predetermined thickness, so that, in a state of the first door  40  and the second door  50  are closed, the rotating bar may come into close contact with the gaskets  42  and  52  by the magnetic force of the magnets  42   a  and  52   a  that are included in the gaskets  42  and  52 . 
         [0078]    As for the heat generating member  140 , a heating cable may be used, and by being line-contacted with the metallic plate  150 , may supply the minimum amount of heat needed to prevent frost from being formed at the metallic plate  150 . The heat generating member  140 , except for the area that is being line-contacted with the metallic plate  150 , is disposed in a way to be surrounded by the heat insulation member  120 , thereby minimizing heat loss. 
         [0079]      FIGS. 6 to 9  are drawings to describe the operation of the rotating bar of the refrigerator of  FIG. 1 . Referring to  FIGS. 6 to 9 , the operation of the rotating bar of the refrigerator in accordance with one embodiment of the present disclosure will be described in brief. 
         [0080]      FIG. 6  illustrates a normal position of the rotating bar  100  in a state that the door  40  is open,  FIG. 7  illustrates a process of the first door  40  being closed from the state of  FIG. 6 , and  FIG. 8  illustrates a state of the first door  40  and the second door  50  closed. 
         [0081]      FIG. 9  illustrates an abnormal position of the rotating bar  100  in a state that the first door  40  is open. 
         [0082]    As illustrated on  FIG. 6 , in a state that the first door  40  is open, the normal position of the rotating bar  100  is a position at which the rear surface of the rotating bar  100  is approximately perpendicular to the longitudinal direction of the first door  40 . Hereinafter, the position as such is referred to as a vertical position. 
         [0083]    In a state that the rotating bar  100  is at the vertical position, as the first door  40  is closed, as illustrated on  FIG. 7 , the insertion protrusion  161  of the rotating bar  100  may enter an inside the guide groove  62  through a guide groove entry  63  of the guide part  60  that is provided at the body  10 . 
         [0084]    The insertion protrusion  161  that enters an inside the guide groove  62  is rotated along the curved surface of the guide groove  62 , and as the insertion protrusion  161  rotates, the rotating bar  100  is also rotated. 
         [0085]    Finally, as illustrated on  FIG. 8 , when the first door  40  is completely closed, the rear surface of rotating bar  100  is disposed in an approximately horizontal to the longitudinal direction of the first door  40  and of the second door  50 , and thus the rotating bar  100  comes into close contact with the gaskets  42  and  52 , thereby able to seal the gap in between the first door  40  and the second door  50 . Hereinafter, the position of the rotating bar  100  as such will be referred to as a horizontal position. 
         [0086]    Finally, in the process of the first door  40  being closed, the rotating bar  100 , in the order of sequence as illustrated on  FIG. 6 ,  FIG. 7 , and  FIG. 8 , is rotated in clockwise direction on the drawings. 
         [0087]    In addition, on the contrary, in the process of the first door  40  being open, the rotating bar  100 , in the order of sequence of  FIG. 8 ,  FIG. 7 , and  FIG. 6 , is rotated in the counter-clockwise direction with respect to the drawings, and in the state of the first door  40  is completely open, the rotating bar  100  is disposed at the vertical position. 
         [0088]    As the above, as the rotating bar  100  is disposed at the vertical position, the first door  40 , even in a state of the second door  50  being closed, may be closed without having the rotating bar  100  being interfered by the second door  50 , and in addition, the insertion protrusion  161  of the rotating bar  100  may enter the guide groove  62  through the guide groove entry  63 . 
         [0089]    However, in a state that the first door  40  is open, the rotating bar  100  may be disposed at the horizontal position due to an erroneous operation by a user. In this case, in the process of the first door  40  being closed, the rotating bar  100  may be interfered by the second door  50 . In addition, even if the rotating bar  100  does not interfere with the second door  50  since the second door  50  is open, the insertion protrusion  161  may not be able to enter the guide groove  62  through the guide groove entry part  63 , and may collide with the guide body  61 . 
         [0090]    Thus, the first door  40  is not being completed closed, and the cool air of the refrigerating compartment  20  may be discharged, thereby causing a damage on the insertion protrusion  161 . 
         [0091]    Thus, the insertion protrusion  161  of the rotating bar  100  of the refrigerator in accordance with one embodiment of the present disclosure is configured to be vertically movable, so that the insertion protrusion  161  is inserted into the guide groove  62  without being collided with the guide body  61  even in a state of the rotating bar  100  being at the horizontal position. The structure of the insertion protrusion  161  as such will be described hereinafter. 
         [0092]      FIG. 10  is a drawing showing a structure of the insertion protrusion of the rotating bar of the refrigerator of  FIG. 1 , and  FIGS. 11 to 12  are drawings to describe a vertical movement of the insertion protrusion of the rotating bar of the refrigerator of  FIG. 1 . 
         [0093]    Referring to  FIGS. 10 to 12 , the insertion protrusion  161  includes a body part  166  disposed at an inside the rotating bar  100 , a protrusion part  164  protruded to the outside the rotating bar  100  through the passage part  112  of the rotating bar  100 , a stopper part  165  to prevent the insertion protrusion  161  from being separated to the outside the rotating bar  100 , and an inclined surface  163  formed at the protrusion part  164 . 
         [0094]    The body part  166  is provided at an inside thereof with a hollowness into which an elastic member  162  may be inserted, and the insertion protrusion  161  is elastically biased by the elastic member  162  in a state of that the protrusion part  164  protrudes to the outside the rotating bar  100 . 
         [0095]    At the case  110  of the rotating bar  100 , a supporting part  111  to support the elastic member  162  is provided, and also a supporting bar  111   a  is protruded from the supporting part  111 . At the body part  166 , a supporting bar  166   a  is provided to support the elastic member  162 . 
         [0096]    The protrusion part  164  is provided with an approximately same shape as the passage part  112  while provided with a size smaller than the size of the passage part  112  so as to be able to pass through the passage part  112 . The protrusion part  164  may be provided with the stopper part  165  to limit the protrusion range of the protrusion part  164  to the outside of the protrusion part  164 . 
         [0097]    The inclined surface  163  formed at the protrusion part  164  is configured to convert horizontal force into vertical force, and is configured in a way that the insertion protrusion  161  may move vertically by the horizontal pressing force of the guide body  61  in the process of the first door  40  being closed while the rotating bar  100  is at the horizontal position. 
         [0098]    Thus, as illustrated on  FIG. 9 , if the first door  40  is closed in a state of the rotating bar  100  is at the horizontal position, the insertion protrusion  161  is collided with the guide body  61 , and may descend by the pressing force of the guide body  61 . 
         [0099]    In the state as such, when the first door  40  is completely closed, the insertion protrusion  161  is ascended by the restoration force of the elastic member  162 , and may be inserted into the guide groove  62 . 
         [0100]    According to the structure as the above, the first door  40  of the refrigerator in accordance with one embodiment of the present disclosure, even in a state that the rotating bar  100  is rotated to the horizontal position, may be closed without interference. Thus, the user convenience is enhanced, and the cool air loss due to the incomplete closing of the doors  40  and  50  may be prevented. 
         [0101]    Although a few embodiments of the present disclosure 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 disclosure, the scope of which is defined in the claims and their equivalents.
