[0045] In an embodiment of the present invention, the control unit (15) is described as being placed on the upper surface of the cabinet (10), but the control unit (15) may be provided at various locations on the refrigerator (1) and may be composed of multiple units and placed at different locations.

[0046] The above door (20) may be composed of a refrigerator door (21) and a freezer door (22). The refrigerator door (21) may be configured to open and close the open front of the refrigerator (12) by rotation, and the freezer door (22) may be configured to open and close the open front of the freezer (13) by rotation. Meanwhile, the refrigerator door (21) may be called an upper door as it is provided on the upper side, and the freezer door (22) may be called a lower door as it is provided on the lower side.

[0047] Additionally, the refrigerator door (21) may be provided with a pair of left and right doors so that the refrigerator (12) is shielded by the pair of doors (21, 22). Furthermore, the freezer door (22) may be provided with a pair of left and right doors so that the freezer (13) is opened and closed by the pair of doors. Of course, the freezer door (22) may be configured to be pull-out in a drawer-like manner as needed, and may be configured with one or more doors.

[0048] In the embodiment of the present invention, a bottom-freeze type refrigerator having a freezer compartment (13) located at the bottom is described as an example of a refrigerator with a pair of French-type doors that rotate to open and close a single space. However, the present invention can be applied to any type of refrigerator where a camera module can be installed, regardless of the shape of the refrigerator.

[0049] Meanwhile, at least one of the pair of refrigerator doors (21) may be composed of a main door (40) and a sub-door (30). The main door (40) is rotatably mounted on the cabinet (10) to open and close the refrigerator room (12). Additionally, an opening (41 in FIG. 2) may be formed through the main door (40).

[0050] The sub-door (30) is provided in front of the main door (40) and can be rotatably mounted on the main door (40). The sub-door (30) can open and close the opening (41). Additionally, a viewing section (31) capable of viewing the inside of the opening (41) may be formed in the sub-door (30). The viewing section (31) may be composed of at least one transparent panel and may optionally be configured to make the inside of the opening (41) visible. Additionally, if necessary, the viewing section (31) may be composed of a display device such as an LCD capable of screen output or a transparent LCD.

[0051] Below, we will examine the internal structure of the storage space of the refrigerator (1) with reference to the drawings.

[0052] FIG. 2 is a perspective view of the refrigerator with the door open. FIG. 3 is a drawing showing the state in FIG. 2 without an additional device installed.

[0053] As illustrated in the drawing, the cabinet (10) may include an inner case (102) forming the inner surface of the storage space and an outer case (101) coupled to the inner case (102) and forming the outer surface of the cabinet (10). Additionally, an insulating material (103) formed by injecting a foaming agent may be filled between the inner case (102) and the outer case (101).

[0054] The outer case (101) is formed from a metal material to form the outer shape of the cabinet (10), and the inner case (102) is vacuum-molded from a relatively thin plastic material to form the inner shape of the storage space.

[0055] The inner case (102) may form the upper and lower surfaces and the left and right sides of the refrigerator (12). Additionally, if necessary, the inner case (102) may form at least a portion of the rear surface of the refrigerator (12). Furthermore, the rear surface of the refrigerator (12) may be formed by a grill fan assembly (121). The grill fan assembly (121) may form a flow path for cold air flow within the refrigerator.

[0056] Meanwhile, an additional device (100) may be installed in the inner case (102). The additional device (100) may be optionally installed in the refrigerator (1) to upgrade the function of the refrigerator (1) or to provide additional functions. Additionally, the additional device (100) may have an independent function that is added to the general cooling operation of the refrigerator (1).

[0057] For mounting the additional device (100), a mounting member (200) is formed in the inner case (102), and the additional device (100) may be configured to be selectively mounted by a user on the mounting member (200). At this time, the mounting member (200) is configured to enable power supply and signal processing when the additional device (100) is mounted, and may be configured to automatically recognize and operate when the additional device (100) is mounted.

[0058] Meanwhile, at least one mounting member (200) may be provided inside the refrigerator (12). Accordingly, the user can mount the additional device (100) in an appropriate location depending on the type and function of the additional device (100).

[0059] For example, the mounting member (200) may be provided on at least one of the upper surface and the left and right sides of the inner case (102). Additionally, the mounting member (200) may be placed in an internal component such as the grill pan assembly (121) in addition to the inner case (102). Furthermore, when the additional device (100) is not mounted on the mounting member (200), a cover (190) may be mounted to shield the space formed by the mounting member (200).

[0060] Meanwhile, referring to FIG. 2, an example in which the additional device (100) is mounted may be provided at the center of the upper surface of the inner case (102). For example, the additional device (100) may be a camera device. Thus, the additional device (100) can photograph the inside of the storage space, i.e., the refrigerator room (12).

[0061] In addition to the camera device, the above additional device (100) may include various devices such as a thermal imaging camera, an ion deodorizer, a carbon dioxide detector, a gas sensor, a reader for recognizing barcodes or QR codes, an additional cooling device composed of a thermoelectric element, a Wi-Fi dongle, etc.

[0062] The above additional device (100) may not be provided at the time of purchase of the refrigerator (1), and may be provided for additional purchase by the user as needed or for performance upgrades of the refrigerator (1).

[0063] The additional device (100) can be electrically connected to the controller (14), so that the captured image can be transmitted to the controller (14) and output on the display device or a remote device such as a mobile phone or PC. In addition, the image information obtained from the additional device (100) can be utilized as information for the operation of the refrigerator (1) through processing or transmitted to the user.

[0064] Additionally, the mounting member (200) may be formed to have a sufficient size to allow mounting of various additional devices (100). Furthermore, as shown in FIG. 3, when the additional devices (100) are not in use, a cover may be mounted on the mounting member (200) to shield the mounting member (200). The cover (190) may be formed to have the same color or texture as the inner case (102) and may have a sense of unity with the inner case (102) when mounted on the mounting member (200). Additionally, the cover (190) may be formed such that when mounted on the mounting member (200), the outer surface of the cover (190) is positioned on the same plane as the inner case (102).

[0065] In this way, the user can mount the additional device (100) at a location suitable for the additional device (100) among a plurality of mounting members (200), and a cover (190) is mounted on the mounting member (200) where the additional device (100) is not mounted so that the interior of the mounting member (200) is not exposed.

[0066] Below, the structure of the above-mentioned mounting member and additional device will be examined in more detail with reference to the drawings.

[0067] FIG. 4 is a cross-sectional view of an additional device mounted according to an embodiment of the present invention. FIG. 5 is a schematic diagram showing the coupling structure of a mounting member and an additional device that are coupled to each other. FIG. 6 is a cross-sectional view of the additional device separated.

[0068] As illustrated, the mounting member (200) can be mounted in the inner case (102). The mounting member (200) can be mounted so as to be exposed through an opening formed in the inner case (102), and a portion of it can be embedded in the insulation material (103) to firmly secure the mounting position.

[0069] The mounting member (200) may include a case (210) that forms a recessed mounting space (211) so that the additional device (100) can be mounted. The case (210) may be open toward the refrigerator room (12). A folded rim (214) may be formed around the perimeter of the open side of the case (210). The rim (214) may be combined with the inner case (102) to secure the mounting member (200) and prevent leakage of the insulation material (103).

[0070] The mounting space (211) may form a space in which the main body (120) of the additional device (100) is accommodated. Additionally, the mounting space (211) may be formed in a shape corresponding to the main body (120).

[0071] For example, as illustrated in FIG. 5(a), a case fitting portion (213) may be formed around the inner surface of the case (210). The case fitting portion (213) may be formed in a shape in which a part of the mounting space (211) is cut out.

[0072] And, as shown in FIG. 5(b), a main body fitting portion (123) may be formed around the outer surface of the main body (120). The main body fitting portion (123) may be formed at a position corresponding to the case fitting portion (213).

[0073] Accordingly, when the additional device (100) is mounted on the mounting member (200), the main body (120) is inserted into the inside of the case (210), and at this time, the case fitting part (213) and the main body fitting part (123) can be mounted in a manner where they come into contact with each other. That is, the additional device (100) can be mounted on the mounting member (200) with a directional orientation, and thus the additional device (100) can be mounted in an accurate position without being mismounted. Furthermore, through such a mounting structure, the first connecting part (220) of the mounting member (200) and the second connecting part (130) of the additional device (100) can be accurately connected.

[0074] A mounting portion (214) having the first connecting portion (220) may be formed on the inner surface of the case (210). The mounting portion (214) may be further recessed in the mounting space (211) and may be configured so that the first connecting portion (220) is mounted inside.

[0075] The mounting portion (214) may be extended in the opposite direction to the opening of the case (210), and its end may be bent to support the end of the first connecting portion (220). Thus, even if the first connecting portion (220) is pressed when mounting the additional device (100), the first connecting portion (220) may not be detached. Also, the mounting portion (214) may be in communication with the mounting space (211), so that if a malfunction occurs in the first connecting portion (220), the first connecting portion (220) can be separated from the mounting portion.

[0076] Meanwhile, the first connecting part (220) may include a first body (222) that is fixed to the mounting part (214) and a first terminal (221) provided on the first body (222).

[0077] The first body (222) may be formed in a shape corresponding to the mounting part (214) so ​​that it can be inserted into and fixed inside the mounting part (214). Additionally, a first coupling part (223) that is coupled to the open circumference of the mounting part (214) may be formed at the end of the first body (222). Furthermore, the first body (222) may be formed in a recessed shape so that the second connecting part (130) can be inserted.

[0078] The first terminal (221) is formed in the recessed center of the first body (222) and may protrude in the insertion direction of the second connecting part (130). It may also be electrically connected to the second terminal (131) of the second connecting part (130) by contacting each other. The first terminal (221) and the second terminal (131) may be formed in a male-female structure and connected to each other. For example, the first terminal (221) and the second terminal (131) may be formed like a standardized USB terminal structure. Additionally, the first terminal (221) and the second terminal (131) may have other standardized terminal structures that can be electrically connected to each other.

[0079] A guide portion (212) for guiding the mounting of the additional device (100) may be formed on the mounting member (200). The guide portion (212) may be formed on one side of the case (210) that is the same as the surface on which the mounting portion (214) is formed. That is, the guide portion (212) may be formed on the case (210), and the guide portion (212) may be formed on both sides relative to the mounting portion (214).

[0080] The guide portion (212) may be formed in a groove shape into which a guide projection (122) protruding from the additional device (100) is inserted. The guide portion (212) may be formed with a size and shape corresponding to the guide projection (122). Accordingly, when the additional device (100) is mounted on the mounting member (200), the guide projection (122) can be inserted into the guide portion (212). And, as the guide projection (122) is inserted into the guide portion (212), the mounting position of the additional device (100) can be guided, and the first connecting portion (220) and the second connecting portion (130) can be naturally combined. That is, when the additional device is mounted so that the guide projection (122) is inserted into the guide portion (212), the first connecting portion (220) and the second connecting portion (130) are connected to each other, and the additional device (100) can be put into an operable state. At this time, the guide projection (122) and the guide portion (212) may be locked or pressed together, and the additional device (100) may be kept in a mounted state on the mounting member (200).

[0081] The additional device (100) may include a main body (120) accommodated in the mounting space (211) and a device cover (110) that shields the mounting space (211).

[0082] The main body (120) may be formed in a shape corresponding to the mounting space (211) of the mounting member (200). Additionally, a main body fitting portion (123) may be formed on one side of the circumferential surface of the main body (120). The main body fitting portion (123) may be formed in a shape corresponding to a position facing the case fitting portion (213). Accordingly, during the process of inserting the main body (120) into the mounting space (211), the additional device (100) can be mounted with the mounting position aligned.

[0083] A receiving space (121) may be formed inside the main body (120) to accommodate a module (140) for operating the additional device (100). For example, if the additional device (100) is a camera device, the module (140) may be a camera module. The module (140) may include a substrate and may be placed inside the main body (120). The module (140) may be electrically connected to the second connection part.

[0084] The second connecting part (130) may protrude from the main body (120) and may be formed in a position facing the first connecting part (220). The second connecting part (130) may include a second terminal (131). The second terminal (131) may be formed to accommodate the first terminal (221), and when the first connecting part (220) and the second connecting part (130) are combined, the first terminal (221) and the second terminal (131) may come into contact with each other and be electrically connected. That is, power for the operation of the additional device (100) may be supplied through the connection of the first terminal (221) and the second terminal (131). In addition, the connection between the first terminal (221) and the second terminal (131) can be established to enable the transmission of a signal between the additional device (100) and the control unit (15). Accordingly, the additional device (100) can perform a set operation and transmit information generated by the operation to the control unit (15).

[0085] A guide projection (122) may be formed on the main body (120). The guide projection (122) may be formed on the same surface as the second connecting part (130). Additionally, the guide projection (122) may protrude from the surface facing the guide part (212).

[0086] A pair of guide protrusions (122) may protrude from both sides of the second connecting part (130). The guide protrusions (122) may protrude in the same direction as the protrusion of the second connecting part (130). Also, the protrusion height (H2) of the guide protrusions (122) may be formed to be higher than the protrusion height (H1) of the second connecting part (130). That is, the protruding end of the guide protrusions (122) may protrude further than the protruding end of the second connecting part (130). Therefore, even if the additional device (100) falls or collides with other components, it can be protected by the guide protrusions (122), and by preventing contact with the second connecting part (130), the second connecting part (130) can be prevented from being damaged.

[0087] And, when the end of the guide projection (122) is completely inserted into the guide portion (212) and comes into contact with the bottom of the guide portion (212), the first connecting portion (220) and the second connecting portion (130) can be completely coupled to each other. Therefore, the connection state between the first connecting portion (220) and the second connecting portion (130) can be confirmed and guaranteed by the coupling of the guide projection (122) and the guide portion (212).

[0088] The additional device (100) may further include a device cover (110). The device cover (110) may form one side of the main body (120) and may cover the opening of the mounting member (200). The device cover (110) may extend outward along the perimeter of the main body (120) and may cover the opening of the mounting space (211). Thus, when the additional device (100) is mounted on the mounting member (200), the device cover (110) may be exposed to the storage space to form the exposed exterior of the additional device (100).

[0089] Additionally, depending on the type of the additional device (100), at least a portion of the module (140) may be exposed through the device cover (110). For example, if the additional device (100) is a camera device, a portion of the camera device may be exposed through the device cover (110) and may be used to photograph food inside the storage space.

[0090] Below, we will examine in more detail the state in which the additional device (100) is mounted and not mounted with reference to the drawings.

[0091] FIG. 7 is a cross-sectional view taken along line VII-VII' of FIG. 2. FIG. 8 is an exploded perspective view of the additional device.

[0092] As illustrated, the mounting member (200) is mounted on the inner case (102), and the mounting space (211) inside the mounting member (200) may provide a space that is more recessed than the outer surface of the inner case (102).

[0093] Meanwhile, due to the mounting of the mounting member (200), the space between the inner case (102) and the outer case (210) is reduced, and an insulating member (104) may be further placed on the mounting member (200). Unlike the insulating material (103), the insulating member (104) may be mounted in a molded state and may be formed in the shape of a plate or sheet covering the mounting member (200). The insulating member (104) may be formed from a material having superior thermal insulation performance than the insulating material (103). That is, the insulating member (104) may be formed from a material having a greater thermal insulation coefficient than the insulating material (103). As an example, the insulating member (104) may be formed from a vacuum insulating material. By placing the insulating member (104) on the outer surface of the mounting member (200), it is possible to prevent the insulation performance from deteriorating at the location where the mounting member (200) is mounted.

[0094] Additionally, the additional device (100) may include the main body (120) and the device cover (110). The main body (120) may be formed so that its lower surface is open and may be formed to accommodate the module (140) inside. Additionally, an opening (123) through which the first connecting part (220) protrudes may be formed on the upper surface of the main body (120). Additionally, the guide projection (122) may be formed on both sides of the opening (123).

[0095] The device cover (110) may include a plate portion (111) that shields the open lower surface of the main body (120) and a rim portion (112) around the plate portion (111). Accordingly, the device cover (110) may be formed with an open upper surface. Additionally, the lower end of the cover main body (120) may be mounted so as to be in contact with the rim portion (112).

[0096] Meanwhile, the module (140) can be fixedly mounted on the inner side of the device cover (110). The module (140) can be attached to the device cover (110) by means of a screw (115). Therefore, to service the module, the device cover (110) can be removed to access the module (140). Additionally, a boss (113, 114) to which the screw (115) is fastened can be further formed on the device cover (110). Multiple bosses (113) can be formed. The screw (115) passing through the boss (113) can be fastened to the inner side of the main body (120). Thus, the device cover (110) and the main body (120) can maintain a state of being firmly coupled by means of the screw (115). Also, although not described in detail, the space between the device cover (110) and the main body (120) may be sealed to prevent water or moisture from penetrating.

[0097] FIG. 9 is a cross-sectional view taken along line IX-IX' of FIG. 3. FIG. 10 is a perspective view of a cover according to an embodiment of the present invention.

[0098] As illustrated, when the additional device (100) is not mounted, the cover (190) can be mounted on the mounting member (200) to shield the mounting space of the mounting member (200). Additionally, the recessed space of the mounting member (200) is prevented from being exposed, and a portion of the inner surface of the storage space can be formed by the cover (190).

[0099] In addition, by mounting the cover (190), the second connecting part (130) inside the mounting space (211) can be prevented from being exposed, and thus, damage to the second connecting part (130) and safety accidents can be prevented.

[0100] The above cover (190) may include a plate-shaped cover plate (191) and a cover edge (192) folded along the perimeter of the cover plate (191). When the cover (190) is mounted on the mounting member (200), the cover plate (191) shields the mounting space (211), and the cover edge (192) may come into contact with the inner perimeter of the mounting space (211).

[0101] Meanwhile, a plurality of cover fixing parts (193) may be formed on the inner side of the cover (190). The cover fixing parts (193) may extend upward from the cover plate (191) or the cover edge (192) and may be formed to be caught and restrained on the inner surface of the mounting case (210) when the cover (190) is mounted.

[0102] The cover fixing part (193) may be formed on both sides facing each other so that both sides of the cover (190) can be connected to the mounting member (200). Additionally, the cover fixing part (193) may be formed to have elasticity, so that when the cover (190) is detached, the cover fixing part (193) can be elastically deformed and connected to the mounting case (210).

[0103] Meanwhile, the insulating member (104) is disposed on the outer surface of the mounting member (200) so that the insulating performance can be maintained even if the mounting space (211) of the mounting member (200) is empty.

[0104] Below, the operation of the above refrigerator (1) will be described in detail with reference to the drawings.

[0105] FIG. 11 is a block diagram schematically showing the connection status of the main components of the refrigerator. FIG. 12 is a flowchart sequentially showing the operation of the refrigerator following the installation of the additional device.

[0106] As illustrated in the drawing, when power is supplied to the refrigerator (1), the drive unit (16), which consists of components for cooling such as the compressor of the refrigerator (1), is driven, and the operation of the refrigerator (1) can begin. At this time, the control unit (15) controls the operation of the drive unit (16) according to the operation input from the operating unit (17). The control unit (15) controls the operation of the drive unit (16) so that the temperature of the storage space detected by the temperature sensor (18) is maintained at a set temperature, and such normal operation can be referred to as general operation. [S100]

[0107] When normal operation has started, the user may install an additional device (100) on the refrigerator (1) as needed. At this time, the location where the additional device (100) is installed may be a set location among a plurality of mounting members (200), such as a first mounting member (200) and a second mounting member (200), and the user may install the additional device (100) at a location suitable for the operation of the additional device (100).

[0108] To mount the additional device (100), the user separates the cover (190) from the mounting member (200) to expose the second connecting part (130), and mounts the additional device (100) in the mounting space (211) where the second connecting part (130) is exposed. [S210]

[0109] When the first connection part (220) and the second connection part (130) are connected to each other by mounting the additional device (100), the control unit (15) can recognize the additional device (100).

[0110] When the additional device (100) is mounted on the mounting member (200), power is supplied to the additional device (100), and the additional device (100) and the control unit (15) are connected in a state where they can communicate, so that the information of the additional device (100) can be recognized.

[0111] At this time, the control unit (15) may store a program for operating the additional device (100). Also, if the refrigerator (1) is equipped with a communication unit (19) and has a structure capable of communicating with the outside, the program for operating the additional device (100) may be received from a remote location and installed. Furthermore, when the additional device (100) is released through periodic communication with a remote location, the program for operating the additional device (100) may be updated in the control unit (15) regardless of whether the additional device (100) is installed. Of course, the program for operating the additional device (100) may be embedded in the additional device (100), and the program for operating the additional device (100) may be installed in the control unit (15) along with the installation of the additional device (100). [S220]

[0112] When the mounting and recognition of the additional device (100) is completed, the control unit (15) activates a corresponding program for the operation of the additional device (100). That is, among the various programs of additional devices (100) installed in the control unit (15), the information of the additional device (100) actually mounted is recognized, and a corresponding program is activated accordingly. [S230]

[0113] After the mounting and recognition of the additional device (100) is completed and the corresponding program for operating the additional device (100) is activated, the normal recognition state of the additional device (100) can be guided.

[0114] For example, the output unit (141) or a remote user terminal can be notified of the completion of normal recognition of the additional device (100) and the state in which the operation of the additional device (100) is waiting. [S240]

[0115] Meanwhile, once the normal mounting and recognition of the additional device (100) is completed, the additional device (100) can be operated according to a set corresponding program. Although it may vary depending on the type of the additional device (100), if the normal activation of the corresponding program is achieved, the additional device (100) performs the set operation along with the recognition of the additional device (100).

[0116] Of course, the user may set and operate the operation of the additional device (100), and while the corresponding program is activated, the user may set the operation of the additional device (100) through the operation of the control unit (17) or through the user terminal. [S250]

[0117] While the operation of the additional device (100) is performed by the above corresponding program, the control unit (15) controls the driving unit (16) to continue normal operation. Of course, depending on the type and operation of the additional device (100), other operation dependent on or modified by the additional device (100), rather than the normal operation, may be performed. [S120]

[0118] Meanwhile, if the additional device (100) is not properly mounted on the mounting member (200) during the process of mounting the additional device (100), or if the additional device (100) is not properly recognized due to other problems, the unrecognized state of the additional device (100) is indicated.

[0119] That is, the control unit (15) can notify the user that there is a problem with the mounting or recognition of the additional device (100) through the output unit (141) or the user terminal. At this time, the control unit (15) can analyze which part of the mounting or recognition of the additional device (100) the problem occurred in and notify the user, and the user can take appropriate measures to resolve the problem.

[0120] Additionally, the user may mount multiple additional devices (100), and multiple additional devices (100) may be selectively mounted at appropriate locations on multiple mounting members (200), such as a first mounting member (201) and a second mounting member (202).

[0121] In addition, the recognition and activation of the additional device (100) may be performed by repeating the aforementioned process sequentially, and when multiple additional devices (100) are installed at once, multiple additional devices (100) may be recognized simultaneously.

[0122] In addition to the aforementioned embodiments, various other embodiments of the present invention may be possible.

[0123] Unlike the previously described embodiment according to another embodiment of the present invention, the additional device may be placed on the door side rather than the cabinet within the storage space. Of course, the additional device may be mounted in a combination of the mounting positions of the previously described embodiment as well as the mounting positions of other embodiments described below.

[0124] Hereinafter, the additional device according to another embodiment of the present invention will be examined with reference to the drawings. Since the basic structure of the additional device and the mounting member is the same and only the placement positions of the additional device and the mounting member differ, detailed descriptions and illustrations of identical components will be omitted, and they will be described using the same reference numerals.

[0125] FIG. 13 is a partial perspective view showing the mounting state of the additional device according to another embodiment of the present invention.

For example, the additional device (100') may be a camera device, and the additional device (100') may photograph and analyze food stored in the opening (41) or in a space connected to the opening (41).

[0129] The door liner (33) may be provided with a mounting member (200'), and the additional device (100') may be detachably mounted to the mounting member (200'). Additionally, a plurality of the mounting members (200') may be provided on the door liner (33). Accordingly, the additional device (100') may be mounted by the user according to the user's needs.

[0130] In detail, as shown in FIG. 13 (a), when the additional device (100') is mounted on the mounting member (200'), the mounting member (200') can be shielded by the device cover (110') of the additional device (100'), and the module (140') can be exposed through the device cover (33) to photograph the interior of the opening (41).

[0131] Meanwhile, as illustrated in FIG. 13(b), if the use of the additional device (100') is not required, the cover (190') may be mounted on the mounting member (200') instead of the additional device (100'). The cover (190') shields the mounting member (200') so that the mounting space (211) is not exposed, and the cover (190') forms part of the rear exterior of the sub-door (30).

[0132] As such, the additional device (100') may be mounted on the rear of the sub-door (30), and although not illustrated in detail, it may be placed on the rear of the door (20, 40) in the same manner.

[0133] FIG. 14 is a partial perspective view showing the mounting state of the additional device according to another embodiment of the present invention.

[0135] The above refrigerator door (21) may be composed of a pair of French-type doors arranged side by side. Additionally, the pair of refrigerator doors (21) may be rotated so that the refrigerator (12) can be partially or completely opened or closed.

[0136] Additionally, a filler (203) may be provided at the end of one of the two refrigerator doors (21). The filler (203) shields the space between the two refrigerator doors (21), and may be extended vertically along the end of the refrigerator door (21) and may be rotatably mounted.

[0137] The above filler (203) can be rotatably mounted on one end of the refrigerator door (21), that is, on the end adjacent to the other refrigerator door (22). The above filler (203) can be mounted on the door liner (202) forming the rear surface of the refrigerator door (21). Then, when the refrigerator door (21) is open, it remains in a folded state on the side end of the refrigerator door (21), and when the refrigerator door (21) is closed, it unfolds by rotation to shield the space between the pair of refrigerator doors (21).

[0138] Meanwhile, an additional device (100'') may be provided on one side of the filler (203). For example, the additional device (100'') may be a camera device, and the additional device (100'') may photograph and analyze food stored inside the refrigerator (12).
