    As follows, a refrigerator according to an exemplary embodiment of the present invention will be described with reference to the attached figures.
    Referring to FIG. 1, a general structure of the refrigerator will be described. A side by side refrigerator is a model for describing the present invention for convenience, although the present invention is not limited to that purpose.
    A first storage chamber 12 is defined in a cabinet 10 of the refrigerator 1 to preserve food items inside. The first storage chamber 12 may include a freezing chamber 12b and a cooling chamber 12a. According to a side-by-side refrigerator, the freezing chamber 12b and the cooling chamber 12a are arranged horizontally, that is, side by side.
    A first door 20 is provided in the cabinet 10 to selectively open and close the first storage chamber 12. A second door 40 is provided on the first door 20 to preserve food items inside, and the second chamber 40 is opened and closed by a second door 30 selectively.
    Each of the above configurations will be described in detail below.
    6/13
    The first storage chamber 12 defined in the cabinet 10 of the refrigerator 1 is divided between the freezing chamber 12b and the cooling chamber 12a by the dividing wall 14. Here, at least one shelf and drawer can be installed in the first storage chamber 12.
    The second storage chamber 40 is defined by the first door 20 and has a predetermined space for preserving food items. The second storage chamber 40 is configured to surround the predetermined defined space. That is, the second storage chamber 40 has a predetermined space positioned inside the door 20 so that the second storage chamber 40 is accessible from outside the first door 20. In this embodiment, the second storage chamber 40 is accessible via of an interior of the first door 20, and the second storage chamber 40 is accessible through a second door 30 coupled to the outer surface of the first door 20. Another type of storage space, specifically, a door basket 25 can be defined in the inside a first door 20, different from the second storage chamber 40. The door basket 24 is accessible from the inside of the first door 20. That is, the door basket 25 is not accessible through the second door 30 and the door basket is accessible after the first door 20 is opened.
    In some examples, the second storage chamber 40 is typically a predetermined enclosed space and may include a structure capable of providing cold air to the second storage chamber 40. The second storage chamber 40 may include a first communication part 46 in communication with the first storage chamber 12, such that the cold air from the first storage chamber 12 is supplied to the second storage chamber 40. A second communication part 48, in direct communication with one end of a cold air duct 18 positioned in the partition wall 14 of cabinet 10, can be defined in a second storage chamber 40.
    Referring to FIG. 2, the first door and the second door will be described in detail.
    The first door 20 includes a protection part 21 (see FIG. 3) recessed towards the cabinet 10 and a second door 30 can be protected in a protection portion 21. A step 29 positioned towards the cabinet 10 is defined in a predetermined portion of the first port 20, for example,
    7/13 approximately a central portion of the first door shown in FIGS. 2 and
    3.
    The appearance of the second door 30 may correspond to the appearance of the first door 20, although it may be configured otherwise. In particular, the width of the second door 30 can be substantially identical to the width of the first door 20 and the height of the second door 30 can be adjustable. The thickness of the second door 30 can be identical to the thickness of the protection part 21. In this embodiment, the position or height of the second door 30 defined in a predetermined portion of the first door 20 can be changed or adjusted, and a user recognizes a second port 30 as the first port 20 itself or part of the first port 20, such that the beauty of the refrigerator 1 is not impaired.
    In the embodiment, a first indentation 26 which is indented inwardly can be located in a predetermined portion of the first door 20, for example, between a lower surface of the second door 30 and a coupling part 24 which is rotatably coupled to the first door. A second indentation 28 indented downwards from the first indentation 26 can be located on the first door 20. A third indentation 36 indented upwards from the bottom surface of the second door 30, which is adjacent to the first indentation 26, can be located at a second door 30. This configuration allows the second and third indentations 28 and 36 to function as handles for the first and second doors, respectively, and thus auxiliary handles do not need to be provided in the first and second doors 20 and 30.
    A projection part 34, projected upwards, is defined in the second door 30 and a seal 35 can be coupled to a circumstance of the projection part 34 to seal the second door 30.

    The first door 20 selectively opens and closes the first storage chamber 12 and the second door 30 selectively opens and closes the second storage chamber defined in the first door 20. In this embodiment, the rotational direction of the first door 20 is identical to that of the second door 30. For example, the first door 20 is rotatable with respect to a vertical rod in a conventional refrigerator and the second door 30 is also rotatable with respect to the vertical rod.
    8/13
    If the rotational direction of the first door 20 is identical to that of the second door 30, the rotational radius of the conventional refrigerator 1 can be determined based on the first door 20 for opening and closing the first storage chamber. As a result, the user must arrange the refrigerator without any obstacles placed in the rotational radius of the first door 20. Also, if the rotational direction of the second door 30 is identical to that of the first door, it may be possible to increase the size of the second storage chamber. defined in the first door 20. Also, if the rotational directions of the first and second doors 20 and 30 are identical, the sealing structure between the first and second doors 20 and 30 may be applicable for the sealing structure between the cabinet 10 and the first door 20.
    Here, the rotating rod of the first port 20 is parallel to the rotating rod of the second port 30 and it is preferable that the rotating rods of the first and second ports 20 and 30 are located on the same line, such that only a single rotating rod can be used to simplify a refrigerator assembly structure.
    This configuration will be described in detail below.
    Referring to FIG. 4, a structure for selectively opening and closing the first door 20 and the second door 30 includes a first connecting member 110, a second connecting member 120 and a rotating rod 130.
    One end of a first connecting member 110 is coupled to an upper surface 14 of the cabinet 10 and the other end of the connecting member 110 is connected to an upper surface of the second door 30 through the middle of the rotating rod 130. One end of a second connecting member 120 is coupled to an upper surface of the first port 20 and the other end of the second connecting member 120 is connected to the upper surface of the second port 30 through the middle of the same upper rotational rod 130. In this embodiment, the second member connecting rod 120 may be located below the first connecting member 110. As a result, the upper rotating rod 130 is employed as a common upper rotating rod for the first and second ports 20 and 30.
    Referring to FIG. 3, a rotational rod 132 for a lower portion of the second port 30 is defined on a lower surface of the second port 30. The lower rotational rod 132 is connected to the coupling part 24, as shown in FIG. 2. The coupling part 24 can be defined in the protection part 21 of the first port 20. A rotational rod 134 for a portion
    9/13 bottom of the first door 20 is provided on a bottom surface of the first door 20 and a rotational rod of the first bottom door 134 is connected to a bottom surface of the cabinet 10 by a third connecting member 140, as shown in FIG. 4.
    FIG. 4a shows a configuration of the upper structure in a closed state of the first and second doors 20 and 30.
    FIG. 4b shows an upper structure configuration in an open state of the first and second doors 20 and 30. A user can open the second door 30 to reach the second storage chamber 40 defined in the first door 20. If the user pulls only the second door 30 in a forward direction using the handle 36 as shown in FIG. 1, the second door 30 is rotated with respect to the common upper rotational rod 130 and the lower rotational rod 132 (see FIG. 3) so that the second storage chamber 40 is thus opened.
    FIG. 4c shows a configuration of the upper structure in an open state of the first door 20.
    The user can open the first door 20 to reach the first storage chamber 12. If the user pulls the first door 20 forward using a handle 28 as shown in FIG. 1, the first and second doors are rotated together with respect to the common upper rotational shaft 130 and the rotational shaft of the first lower gate 134 (see FIG. 3) and then the first storage chamber 12 is opened. In this embodiment, the second connecting member 120 is rotated such that the first and second ports 20 and 30 can rotate together.
    As an example, FIG. 5 shows a handle 27 for opening and closing the first door 20 and a handle 37 for opening and closing the second door positioned on external surfaces of the first and second doors 20 and 30, respectively. As mentioned in the description, an indentation used as a handle can be defined on the first and second doors, respectively.
    Referring to FIG. 6, this mode is similar to the previous mode, for example, two door frames, but the structure for selectively opening and closing the first door 20 and the second door 30 is modified. For example, the appearance of the protective part 21 of the first door 20 is modified. As shown in FIG. 3, in the previous embodiment, an upper portion of the protection part 21 of the first door 20 is exposed such that the upper surfaces of the
    10/13 first and second ports 20 and 30 are on an identical level. In this embodiment, a projection part 39 is defined in an upper portion of the first door 20 to rotatively couple the upper surface of the second door 30 to a lower surface of the projection part 39. As a result, the upper surface of the second door 20 is located under the projection part 39 of the first door 20.
    As shown in FIG. 6, a pair of rotating rods for the first port 139 can be provided in the first port 20 and a pair of rotating rods for the second port 138 can be provided in the second port 30. The rotating rod of the first port 139 and the rotating rod of the second port 138 are parallel, but not flush.
    In some embodiments, the rotational rod of the first port 139 and the rotational rod of the second port 138 may be located on the same rod line. In that case, an upper rotational rod of the first port 20 and a rotational rod of the second port 30 can be on the same rotational rod line.
    In the case of a protection part structure 21a, a hinge structure can be installed on internal surfaces of the first and second doors 20 and 30, instead of the rotational rod 138 of the second door 30.
    FIGS. 5 and 6 show a handle 27 for the first door and a handle 37 for the second door provided on external surfaces of the first and second doors 20 and 30, respectively, and the present invention is not limited to that purpose. As mentioned in the description of the modality above, the recoil used as handles can be provided in the first and second doors, respectively.
    The side-by-side refrigerator is presented to describe the modalities and, therefore, the present invention is not limited to that purpose. The present invention is applicable to a type with freezer on the top containing a freezing chamber positioned in a refrigeration chamber or a type with freezer on the bottom containing a freezing chamber arranged under a refrigeration chamber. Referring to FIG. 7, the present invention may be applicable to a refrigerator containing the refrigeration chamber arranged in the upper portion of the cabinet and the freezing chamber defined in a lower portion of the cabinet. Also, the present invention can be applicable to a refrigerator containing a lockable freezing chamber that
    11/13 is a type of drawer and a refrigeration chamber containing a pair of open or closed doors in relation to a pair of vertical rods.
    In addition, the appearance of the first door corresponds to that of the second door. For example, the width of the first door is identical to the width of the second door and the length of the second door is less than the length of the first door. Here, the present invention is not limited to that purpose. That is, the present invention can be applied to a case where both the width and the height of the second door can be smaller than those of the first door.
    The refrigerator may include another type of door that is rotatable along a predetermined rotational direction other than that of the first door. Referring to FIGS. 8 and 9, this case will be described in detail below.
    Unlike the above embodiments, a refrigerator shown in FIGS. 8 and 9 include a third storage chamber and a third door 500 for selectively opening and closing the third storage chamber. Here, the third door 500 has a rotational direction that is different from the first door 20 and the second door 30, for example, perpendicular to the rotational direction of the first door 20 or the second door 30.
    The third storage chamber and the third port 500 will be described below. For a convenient explanation, the refrigerator described with reference to FIG. 2 may additionally include the third storage chamber and the third port 500.
    The third storage chamber is positioned on the first door 20 and has a predetermined space for preserving food items inside. The third storage chamber is typically configured to surround the defined space. That is, the third storage chamber has a predetermined space on the third door 500 and is accessible from the outside of the first door 20 basically. Not excluding that the third storage chamber is accessible from the inside of the first door 20, the third storage chamber is accessible through the third door 500 provided on the outer surface of the first door 20. Depending on the surrounding space configuration, the third The storage chamber can have a structure that allows cold air to be supplied for this purpose.
    As an example, the third storage chamber works similarly to the second storage chamber 40. Here, the second storage chamber 40 and the third storage chamber do not need to be
    12/13 physically separated and form a single space, accessible through the second and third doors 20 and 500, respectively.
    Although it is possible that the second storage chamber 40 and the third storage chamber should be positioned separately at a predetermined distance from each other, the second storage chamber 40 and the third storage chamber may be adjacent to each other, with space configuration single. The structure of the entire storage chamber can be simplified.
    As mentioned above, the third door 500 can have a predetermined rotational direction different from the first door 20, for example, perpendicular to the rotational direction of the second door 30. Because of this, the third door 500 can be used as a backer in an open state. This setting allows recategorized food items. For example, having high frequency of use to be preserved in the second storage chamber 40 and the third storage chamber.
    The coupling and opening / closing structure of the first, second and third storage chambers will be described below.
    A first indent 26 towards the cabinet, i.e. the storage chamber is provided in a predetermined portion, for example, a lower portion of the first door 20. A third indent 36 is adjacent to the first indent 26 and the third indent 36 it is used as a handle for the second door 30. A fourth indentation 500a is adjacent below the first indentation 26 and the fourth indentation 500a is used as a handle for the third door 500.
    Additionally, a fifth indentation 26a is retreated towards the cabinet, i.e. the refrigerator storage chamber. A second indentation 28a, is adjacent below the fifth indentation 26a and the second indentation 28a is used as a handle for the first door 20.
    As shown in FIG. 9, the third door 500 is coupled to the first door 20, rotatable with respect to a horizontal rod 510. For example, an opening 520 is defined on a front surface of the first door 20 and the third door 500 is rotatively coupled to the opening 520. That is, the rotational rod 510 of the third door 500 is arranged horizontally, and the pair of rotational rods 510 can be arranged in the opening 520 of the first door 20.
    The installation structure of the first, second and third door handles 20, 30 and 500 may not be limited. For example, as shown in
    13/13
    FIG. 10 and 11, auxiliary handles 37 and 27 can be provided on external surfaces of the first and second doors, respectively, and the handle of the third door 500 can be a touch-lock type. Such a touch-lock is installed on the third door 500. If the user presses the third door 500, the third door 500 will open automatically. The closure-touch structure is well known in the art to which the present invention relates and the detailed description of this will be omitted accordingly.
    Alternatively, the handle for the third door can be installed on an external surface of the third door 500 and the touch-lock type can be applicable to the first and second doors 20 and 30.
    As this modality may not use the first recess 26 and the fifth recess 26a for installing the handle, the exterior beauty of the refrigerator can be improved.
    Referring to FIGS. 12 to 14, a refrigerator will be described below.
    A vertically indented groove 550 is provided in a predetermined portion of the first port 20, and a horizontally indented first port 552 indentation and a second indentation 554 are provided in groove 550 as shown in FIG. 13 and FIG. 14. A third door handle can be a touch-lock type. Alternatively, it is possible to open and close the third door 500 using an indentation of the third door provided horizontally in the groove 550. The corresponding figures show that the indentations must have a predetermined length. It is also possible to have indentations along the entire length of the door.
    Here, the above modes can use each handle structure together. For example, the groove formed vertically, the indent formed horizontally and the lock-touch structure.
    It will be understood that various modifications can be made without departing from the spirit and scope of the claims. For example, advantageous results can still be achieved if steps in the revealed techniques are performed in a different order and / or if components in the revealed systems are combined differently and / or replaced or supplemented by other components. Accordingly, other modalities are within the scope of the following claims.
