         [0028]    It is noted that the embodiment describes, by way of example, a case where a refrigerating chamber door is five but is not limited thereto. 
         [0029]    In more detail, in the embodiment, the door may include an upper door  12  that opens and closes the storage chamber provided at a relatively upper side of the main body  11 , a middle door  13  that opens and closes the storage chamber provided at a lower side of the storage chamber opened and closed by the upper door  12 , and a lower door  14  that opens and closes the storage chamber provided at a lower side of the storage chamber opened and closed by the middle door  13 . Each door may be provided with handles  121 ,  131 , and  141 . 
         [0030]      FIG. 2  is a perspective view showing a state where any one of the storage chambers of the refrigerator according to the embodiment of the present invention is opened and  FIG. 3  is an exploded perspective view showing configurations of  FIG. 2 , respectively. 
         [0031]    Referring to  FIGS. 2 and 3 , the present embodiment describes, by way of example, a storage chamber  111  that is selectively opened and closed by the middle door  13 . 
         [0032]    In detail, the rear surface of the middle door  13  is connected with a main container  15  that receives foods or containers, wherein the main container  15  is received in the storage chamber  111  that is defined in the main body  11 . The one side of the inside of the main container  15  may be provided with an auxiliary container  17  for receiving foods or beverage containers. The inside spacer of the main container  15  except for the space in which the auxiliary container  17  is received may be provided with a separate auxiliary cooling chamber  18 . The auxiliary cooling chamber may be provided with a bottle chamber  181  in which beverage bottles are loaded and stored and a quick cooling chamber  182  for quickly cooling beverages. 
         [0033]    In addition, the middle door  13  is tiltably connected to the front surface of the main container  15  and tiltably connected from a vertical state to a horizontal state by a hinge  16 . The upper surface of the middle door  13  may be depressedly formed with a gripping groove  133  at a predetermined depth. Herein, the bottom surface of the middle door  13  may be formed with the gripping recess like the gripping groove  133  instead a handle  131  of the middle door  13 . As a result, the front portion of the middle door forms a smooth plane, such that the exterior of the refrigerator  10  can be processed more sharply. 
         [0034]    Moreover, the front surface of the main container  15  is formed with a front hole  151  for drawing out the auxiliary container  17 . The front surface of the main container  15  corresponding to the front surface of the auxiliary cooling chamber  18  is formed with a hole that receives beverage bottles into the bottle chamber  181  and a door that opens and closes the quick cooling chamber  182 . 
         [0035]    Meanwhile, both side portions of the main container  15  is provided with rails  19  and the inside surface of the storage chamber  111  is provided with a rail guide (not shown) that guides the front and rear direction movements of the rail  19 . 
         [0036]    With the refrigerator having the above-mentioned configuration, the middle door  13  can be horizontally tilted to draw out the auxiliary container  17  in the state where the main container  15  is completely drawn in the inside of the storage chamber  111 . In addition, the main container  15  is drawn out by pulling the middle door  13  in a vertical state, such that the auxiliary container  17  can be drawn out. In this case, the auxiliary container  17  can be drawn out by a lifting operating through the upper opening portion of the main container  15 . The operation method will be described in more detail below with reference to the accompanying drawings. 
         [0037]    Meanwhile, the rear surface of the middle door  13  is formed with a latch  134  and the front surface of the main container  15  may be formed with a latch hole  152  in which the latch  134  is inserted. Therefore, when the user grips the gripping groove  133  formed on the upper surface of the middle door  13  and then pulls it forward, the latch  134  is out of the latch hole  152 , such that the middle door  13  can be tilted in a horizontal state. The latch  134  is operated as a general hanging means but may be used as a one-touch button manner. For example, by a pressing and releasing action onto the front surface of the middle door  13  in the state where the middle door  13  is closely attached to the front surface of the main container  15 , the latch  134  may be out of the latch hole  152 . The rotational shaft portion of the middle door  13  is inserted with an elastic member such as a torsion spring and a hydraulic damper structure, such that the middle door  13  can be automatically rotated to a horizontal state. This structure is frequently applied to a home bar structure for a refrigerator in the related art and therefore, the detailed configuration thereof will be omitted. However, it is noted that the spirit of the present invention can apply the above-mentioned one-touch button and the automatic rotating function. 
         [0038]      FIG. 4  is a perspective view showing a shape where a receiving rack of the refrigerator according to the embodiment of the present invention is drawn out. 
         [0039]    Referring to  FIG. 4 , a receiving rack of the refrigerator can be drawn out from the main container  15  by the operation that rotates the middle door  13  in a horizontal state and then draws out the auxiliary container  17  forward. The foods and the beverage container received in the auxiliary container  17  can be taken out. 
         [0040]    In detail, the middle door  13  is tilted forward by the operation that inserts fingers in the gripping groove  133  formed on the upper surface of the middle door  13  and pulls it, or by the pressing and releasing action onto the front surface of the middle door  13  as described above. Then, the middle door  13  becomes a horizontal state and in this state, the auxiliary container  17  can be drawing out through the front hole  151  of the main container  15 . When the middle door  13  is tilted in a horizontal state, the bottle chamber  181  is exposed, such that the beverage bottles received in the bottle chamber  181  can be easily taken out. In addition, when the middle door  13  rotates horizontally, the front portion of the quick freezing chamber  182  is exposed, such that the user can quickly cool beverage bottles by putting the beverage bottles in the quick cooling chamber  182 . 
         [0041]    Further, the rear surface of the middle door  13 , that is, the surface corresponding to the upper surface when the middle door  13  is in the horizontal state, is formed with a cup supporting groove  132  on which a cup is placed. Therefore, after the user places a cup on the cup supporting groove  132 , he/she can pour and drink beverages in the cup. In other words, the middle door  13  also performs the home bar function. 
         [0042]      FIG. 5  is a perspective view showing a shape where a basket of the refrigerator according to the embodiment of the present invention is drawn out. 
         [0043]    Referring to  FIG. 5 , when the user pulls the handle  131  formed on the front surface of the middle door  13 , the middle door  13  is drawn out forward in a vertical state. Herein, the handle  131  is formed at a position close to the lower end of the middle door  13 , such that the middle door  13  cannot be tilted by a force pulling the handle  131 . Alternatively, the bottom surface portion of the middle door  13  is formed with a groove such as the gripping groove  133 , such that the middle door  13  cannot be rotated during a process of drawing out the middle door. 
         [0044]    In detail, when articles to be drawn out by the user exist the rear end area of the auxiliary container  17 , it may be more convenient that the user draws out the main container forward rather than tilting the middle door  13 . In this case, the user can operate the middle door  13  so that the middle door  13  and the main container  15  are drawn out forward together. 
         [0045]    Meanwhile, when the containers, in which beverages are received, are stored in the storage chamber  111  at a time, it is easy to draw out the containers as well as since the storage positions of the beverage container are not confused, such that the use convenience is increased. 
         [0046]      FIG. 6  is a partial perspective view of a refrigerator according to another embodiment of the present invention. 
         [0047]    Referring to  FIG. 6 , the embodiment is characterized in that the main container  15  is removed from the above embodiment and the middle door  13  is rotatably provided to the front surface of the main body  11  by the hinge  16 . 
         [0048]    In detail, the auxiliary container  17  is received in the storage chamber  111  formed in the main body  11  and the storage chamber  111  is selectively shielded by the middle door  13 . The bottle chamber  181  and the quick cooling chamber  182  may be provided in the storage chamber  111 . Therefore, the bottle chamber  181  and the quick cooling chamber  182  are not drawn out forward and may be fixed in the storage chamber  111 . 
         [0049]    Further, the rear surface of the middle door  13  may be formed with the latch  134  and the front surface of the main body  11  may be formed with the latch hole  112 . The structure of the latch  134  and the latch hole  112  can perform the same configuration and function as one described in the above embodiment and the rotational shaft of the middle door  13  may be provided with the elastic member or the hydraulic damper. 
         [0050]    With the structure, when the foods and containers are stored in the deep spots of the storage chamber  111 , the disadvantages in that it is difficult for the user to find the foods and containers and take out them can be improved. In other words, the auxiliary container  17  can be drawn out such that the foods or the containers stored in the auxiliary container  17  can be confirmed from the outside of the main body  11 . Therefore, it can be immediately confirmed which spots the stored foods or the containers are positioned.
