    DETAILED DESCRIPTION



    [0013] FIG. 1 is a perspective view of a refrigerator according to an example not representative of the present invention, FIG. 2 is a perspective view of a refrigerator in the state where a sub-door according to an example not representative of the present invention is opened, and FIG. 3 is a perspective view of a refrigerator in the state where the refrigerating chamber door and the freezing chamber door according to an example not representative of the present invention are opened.

    [0014] Referring to FIGS. 1 to 3, a refrigerator 1 according to an example not representative of the present invention ncludes a main body 10 in which a storage chamber is formed and doors that open and close the storage chamber.

    [0015] The storage chamber includes a refrigerating chamber 11 that is formed at an upper side portion of the main body and a freezing chamber 13 that is formed at the lower side portion of the main body 10 and is partitioned from the refrigerating chamber 11.

    [0016] The doors includes a plurality of refrigerating chamber doors 21 and 22 that open and close the refrigerating chamber 11 and a freezing chamber door 23 that opens and closes the freezing chamber 13.

    [0017] The plurality of refrigerating chamber doors 21 and 22 are rotatably connected to the main body 10, by way of example and the freezing chamber door 23 is connected to the main body 10 to be slidably drawn in or drawn out, by way of example.

    [0018] The refrigerating chamber 11 has a single space or is partitioned by one or more partitioning part. In the present example, the refrigerating chamber 11, which is formed at the main body 10, may be referred to as a "main refrigerating chamber".

    [0019] Any one (a right door as one example in the present example) of the plurality of refrigerating chamber doors 21 and 22 is provided with a main door 210 (referred to as a first door) that opens and closes a portion of the main refrigerating chamber 11, a sub-door 230 (referred to as a second door) that is rotatably coupled to the main door 210, and a housing 220 that defines a sub refrigerating chamber 221.

    [0020] The housing 220 is coupled to a rear surface of the main door 210.

    [0021] Therefore, the housing 220 is rotated together with the main door 210 when the main door 210 is rotated.

    [0022] In the present example, the housing 220, which forms the sub-refrigerating chamber 221, moves together with the main door 210, such that the sub-refrigerating chamber 221 is formed at the refrigerating chamber door 22 (in particular, main door 210).

    [0023] Therefore, in the present example, the main refrigerating chamber 11 can be opened and closed by the left door 21 and the right door 22 (or main door) and the sub-refrigerating chamber 221 can be opened and closed by the sub-door 230. The sub-refrigerating chamber 221 defined by the housing 220 may include a plurality of receiving parts 222 and 224.

    [0024] The housing 220 is provided with one or more cool air injecting hole 225 that injects cool air into the main refrigerating chamber 11. In addition, the housing 220 is provided with a cover 226 that draws in and out foods stored in the sub-refrigerating chamber 221 in the state where the refrigerating chamber door 22 is opened.

    [0025] The main door 210 is provided with an opening part 211 that draws out and in foods received in the sub-refrigerating chamber 221. The user can draw in or out foods stored in the sub-refrigerating chamber 221 through the opening part 211.

    [0026] The sub-door 230 forms the entire external appearance of the front surface of the right door 22.

    [0027] The sub-door 230 is provided with a guide part 231 that facilitates the door operation of the user. The guide part 231 is extended to a side portion from the side surface of the sub-door 230. The main door 210 also includes a protruding part 212 having a shape corresponding to the guide part 231.

    [0028] The rear surface of the guide part 231 is formed with a latch hook 232 for coupling with the main door 210 and the protruding part 212 of the main door 210 is formed with a latch slot 214 with which the latch hook 232 is coupled.

    [0029] The structure of the latch hook 232 and the latch slot 214 can use the known structure and therefore, the detailed description thereof will be omitted.

    [0030] Therefore, when the front surface of the guide part 231 is pressed in the state where the sub-door 230 is closed, the coupling of the latch hook 232 and the latch slot 214 is released, such that the sub door 230 is opened. On the other hand, when the sub-door 230 is rotated and closed, the latch hook 232 and the latch slot 214 are coupled with each other.

    [0031] Each of the side surfaces of the left door 21 and the main door 210 is formed with door grooves 216 and 217 for providing handles.

    [0032] Therefore, in order to open the left door 21 or the main door 210 (or right door), the user pulls the doors 21 and 210 in the state where his/her fingers put in the door grooves 216 and 217.

    [0033] Although not shown, the rear surface of the left door 21, the rear surface of the main door 210, and the rear surface of the sub-door 230 is provided with a sealer for sealing.

    [0034] Meanwhile, the rear surface of the freezing chamber door 23 can be coupled with a basket 24 for receiving foods. The upper surface of the freezing chamber door 23 is provided with the door groove 231 for providing the handle.

    [0035] The sub-refrigerating chamber 221 may receive frequently used foods or foods for children, etc., by way of examples. In this case, the user opens the sub-door 230 without opening the refrigerating chamber door 22 to draw out necessary foods, thereby increasing the user convenience.

    [0036] In other words, force opening the sub-door 230 is weaker than force opening the refrigerating chamber door 22 including the main door 210 and the sub-door 230, such that the user can draw out foods received in the sub-refrigerating chamber 221 with a little force.

    [0037] FIG. 4 is a partial plan view of the refrigerator according to an example not representative of the present invention.

    [0038] Referring to FIG. 3 and 4, the main door 210 is disposed at the front of the main body 10 and the sub-door 230 is disposed at the front of the main door 210.

    [0039] In other words, when viewed from the upper surface of the refrigerator, the main door 210 and the sub-door 230 are disposed in a row in front and rear directions.

    [0040] The main door 210 can be rotated with respect to the main body by the first hinge assembly 240 and the sub-door 230 can be rotated with respect to the main body and the main door 210 by the second hinge assembly 250.

    [0041] As shown in the drawings, the hinge centers of each hinge assembly 240 and 250 are spaced from each other.

    [0042] Therefore, the main door 210 and the sub-door 230 can be rotated independently without interference with each other by each of the hinge assemblies 240 and 250.

    [0043] In addition, the rotational center of each of the hinge assemblies 240 and 250 is extended in the upper and lower directions of the refrigerator. Therefore, the main door 210 and the sub-door 230 can be horizontally rotated based on the rotational center that is vertically extended.

    [0044] FIG. 5 is a perspective view of a refrigerator in the state where only a refrigerating chamber door according to the present invention is opened and FIG. 6 is a perspective view of a refrigerator in the state where a refrigerating chamber door and a housing according to the invention is opened together.

    [0045] Referring to FIGS. 5 and 6, a refrigerator 300 according to the present invention includes a main body 310 in which a refrigerating chamber 311 and a freezing chamber (not shown) are formed to be partitioned up and down, a plurality of refrigerating chamber doors 320 and 330 that opens and closes the refrigerating chamber 311, a freezing chamber door 340 that opens and closes the freezing chamber.

    [0046] The refrigerating chamber, which is formed at the main body 310, is referred to as a "main refrigerating chamber".

    [0047] Refrigerating chamber doors 320 and 330 is rotatably supported to the main body by the first hinge assembly 335. The first hinge assembly 335 is disposed at the upper side and the lower side of the refrigerating chamber door 330.

    [0048] The main body 310 is movably connected to a housing 312 that defines a sub-refrigerating chamber 313 partitioned from the main refrigerating chamber 311. The housing 312 is rotatably connected and supported to the main body 310 by a plurality of second hinge assemblies 350.

    [0049] One of the plurality of second hinge assemblies 350 is positioned at the upper side of the housing 312 and the other is positioned at the lower side of the housing 312.

    [0050] One end of the second hinge assembly 350 is connected to a side wall of the main refrigerating chamber 311 and the other is connected to the upper side of the housing 312. A structure of the second hinge assembly 350 will be described below with reference to the drawings.

    [0051] The housing 312 can be drawn out to the outside of the main body 310 (or main refrigerating chamber) together with the refrigerating chamber door in the state where the housing 312 is positioned at the main body 310.

    [0052] In other words, the housing 312 and the door 330 are selectively coupled with each other by the coupling apparatus (as will be described below) and in the state where the housing 312 and the door 330 are separated from each other, only the door 330 is rotated to open the sub-refrigerating chamber 313 in the state where the housing 312 is positioned at the main body 310.

    [0053] On the other hand, in the state where the housing 312 and the door 330 are coupled with each other, the housing 312 is rotated together with the door 330 to open the main refrigerating chamber 311.

    [0054] The side surfaces of the door 330 is provided with the door groove 332 for providing the handle.

    [0055] The housing 312 is provided with one or more cool air injecting hole 314 that injects cool air into the main refrigerating chamber 311. In addition, the housing 312 can be provided with a cover 315 that can draw out or in foods stored in the sub-refrigerating chamber 313 in the state where the housing 312 is rotated together with the door 330.

    [0056] The sub-refrigerating chamber 313 can receive frequently used foods or foods for children, etc..

    [0057] FIG. 7 is a diagram showing a structure of the second hinge assembly according to the present invention and FIG. 8 is a cross-sectional view taken along line A-A of FIG. 7.

    [0058] Referring to FIG. 7 and 8, the second hinge assembly 350 according to the present invention includes a first link 352 that is fixed to an inner side wall of the main body 310 and a second link 356 that is slidably connected to the first link 352.

    [0059] The first link 352 is coupled with the main body 310 by a coupling member such as a screw as one example. Each of the first link 352 and the second link 356 is formed in a circular arc shape having approximately 90°.

    [0060] The second link 356 is disposed at the lower side of the first link 352. The lower surface of the first link 352 is formed with the first guide groove 353 and the upper surface of the second link 356 is formed with a first guide protrusion 357 that is positioned at the first guide groove 353. The first guide protrusion 357 is moved along the first guide groove 353.

    [0061] In order to prevent the first guide protrusion 357 from being separated from the first guide groove 353, the first guide protrusion 357 and the second guide groove 353 is formed in a "T" shape as one example.

    [0062] The lower surface of the second link 356 is formed with the second guide groove 358 and the upper surface of the housing 312 is formed with the second guide protrusion 359. The second guide protrusion 359 plays a role of a rotational shaft of the housing 312 and is moved along the second guide groove 358.

    [0063] In order to prevent the second guide protrusion 359 from being separated from the second guide groove 358, the second guide protrusion 359 and the second guide groove 358 is formed in a "T" shape as one example.

    [0064] The second guide protrusion 359, which plays a role of the rotational shaft of the housing 312, can be moved by the first link 353 and the second link 356.

    [0065] In other words, the second link 356 is overlapped with the first link 353 in the state where the housing 312 is positioned at the main body 310 and the second link 356 is sled and is drawn out from the main body 310 in the state where the housing 312 is drawn out to the outside of the main body 310.

    [0066] As such, since the second guide protrusion 359 can be moved, the housing 312 can be rotated together with the refrigerating chamber door 330 in the state where the housing 312 is coupled with the refrigerating chamber door 330 even though the positions of the rotational center of the housing 312 and the rotational center of the first hinge assembly 335 are different from each other.

    [0067] FIG. 9 is a perspective view showing a coupling structure of the housing and the refrigerating chamber door according to the invention and FIG. 10 is a diagram showing the state where the housing and the refrigerating chamber door are coupled with each other.

    [0068] Referring to FIG. 9 and 10, the housing 312 and the refrigerating chamber door 330 are selectively coupled by one or more coupling apparatuses 360 FIG. 9 shows the plurality of coupling apparatuses 360

    [0069] The coupling apparatus 360 includes a first coupling part 362 that is provided at the refrigerating chamber door 330, a second coupling part 364 that is provided at the housing 312 and is coupled with the first coupling part 362, and a driver 367 that drives the first coupling part 362.

    [0070] The first coupling part 362 is received in a receiving part 336 that is formed at the rear surface of the refrigerating chamber door 330. The first coupling part 362 is connected to the driver 367 and is selectively rotated by the driver 367.

    [0071] The first coupling part 362 is formed with a coupling groove 363 to which the second coupling part 364 is hung. The second coupling part 364 is seated to the second coupling groove 363 in the state where the first coupling part 362 is rotated in one direction (a direction coupled with the second coupling part). In other words, the first coupling part 362 supports the second coupling part 364.

    [0072] Therefore, the load of the housing 312 is supported by the second hinge assembly 350 and the coupling apparatus 360 in the state where the housing 312 is rotated together with the refrigerating chamber door 330.

    [0073] The second coupling part 364 is formed in a cylindrical shape as one example and is selectively seated to the second coupling groove 363. The end portion of the second coupling part 364 is formed with a separating prevention part 365 having a diameter larger than a diameter of the second coupling part 364 so that the coupling state of the second coupling part 364 and the first coupling part 362 is stably maintained.

    [0074] The driver 367 is operated by an operating part 333 that is provided at the door groove 332. In other words, when the operating part 333 is pressed once, the driver is rotated in one direction such that the first coupling part 362 and the second coupling part 364 are coupled with each other.

    [0075] On the other hand, when the refrigerating chamber door 330 is closed without operating the operating part 333, the driver 367 is rotated in an opposite direction such that the coupling of the first coupling part 362 and the second coupling part 364 is released. The opening and closing of the refrigerating chamber door 330 can be sensed by the sensor that is not shown.

    [0076] At this time, although the operating part 333 is operated in the state where the refrigerating chamber door 330 is opened and the first coupling part 362 and the second coupling part 364 are coupled, the driver 367 is not operated.

    [0077] This is to prevent the housing 312 from being separated from the refrigerating chamber door 330 in the state where the housing 312 and the refrigerating chamber door 330 are opened together.

    [0078] In the present embodiment, it is noted that the position of the operating part 333 is illustrated by way of example and the position thereof is not limited. As one example, the operating part 333 is provided at the front surface of the refrigerating chamber door 330.

    [0079] In addition, it is noted that the structure of the coupling apparatus 360 is not limited to the present embodiment but various structures can be used.

    [0080] FIG. 11 is a perspective view of a refrigerator according to an example not representative of the present invention, FIG. 12 is a perspective view of a refrigerator in the state where a refrigerating chamber door according to an example not representative of the invention is opened, and FIG. 13 is a perspective view of a refrigerator in the state where the refrigerating chamber door and the freezing chamber door according to an example not representative of the invention are opened together.

    [0081] Referring to FIGS. 11 to 13, a refrigerator 400 of an example not representative of the present invention includes a main body 410 in which a refrigerating chamber 412 is formed, a plurality of refrigerating chamber doors 420 and 430 for opening and closing the refrigerating chamber 414, a housing 413 that is provided at the refrigerating chamber doors 420 and 430 and forms the freezing chamber 414, and a plurality of freezing chamber doors 440 and 450 that is rotatably coupled with each of the refrigerating chamber doors 420 and 430 to open and close the freezing chamber 414.

    [0082] In the present example, the case where the refrigerating chamber door is disposed left and right is described as one example and the structure of the left refrigerating chamber door and the structure of the right refrigeration door are the same, and therefore, only the left refrigerating chamber door will be described below by referring reference numerals thereto.

    [0083] The housing 413 is coupled to a rear surface of the refrigerating chamber door 420. In the present example, the housing 413 moves the refrigerating chamber door 420 together in the state where the housing 413 is fixed to the refrigerating chamber door and therefore, the case where the freezing chamber 414 is formed at the refrigerating chamber door 420 can be also described.

    [0084] Therefore, with the present example, the freezing chamber 414 is selectively positioned inside the refrigerating chamber 412 according to whether the refrigerating chamber door 420 is opened.

    [0085] The refrigerating chamber door 420 is formed with an opening part 421 that can draw out and in foods. Therefore, foods are received in the freezing chamber 414 or are drawn out of the refrigerating chamber 414 through the opening part 421.

    [0086] The freezing chamber door 440 opens and closes the opening part 421 (or freezing chamber) in the state where it is positioned at the front of the refrigerating chamber door 420. In other words, when viewed from the upper surface of the refrigerator 400, the freezing chamber door 440 and the refrigerating chamber door 420 are disposed in a row in front and rear directions of the refrigerator.

    [0087] The freezing chamber door 440 forms the entire external appearance of the front surface of the refrigerator. Therefore, the user can view only the front surface of the freezing chamber door 400 from the outside. However, the entire surface of the freezing chamber door and a portion surface of the refrigerating chamber door 420 can be viewed from the outside by making the size of the freezing chamber door 440 smaller than the size of the refrigerating chamber door 420.

    [0088] The upper side of the housing 413 is formed with an evaporator (not shown) and one or more cool air injecting hole 415 into which heat-exchanged cool air is injected. The inner upper surface of the main body 410 is provided with a cool air duct 416 that forms a channel of a cool air.

    [0089] Meanwhile, the refrigerating chamber door 420 is rotated with respect to the main body 410 by the first hinge assembly 460 and the freezing chamber door 440 can be rotated with respect to the refrigerating chamber door 420 by the second hinge assembly 470.

    [0090] Therefore, the refrigerating chamber door 420 and the freezing chamber door 440 can be rotated independently without interference with each other by each of the hinge assemblies 460 and 470.

    [0091] Meanwhile, the rear surface of the refrigerating chamber door 420 is provided with a sealer 422 for preventing a leakage of cool air from the refrigerating chamber 412 and the inner side of the sealer 422 is provided with a magnet (not shown) for coupling with the main body 410.

    [0092] In addition, the rear surface of the freezing chamber door 440 is provided with a sealer 422 for preventing a leakage of cool air from the freezing chamber 414 and the inner side of the sealer 422 is provided with a magnet (not shown) for coupling with the refrigerating chamber door 420. The magnetic force of the magnet of the freezing chamber door 440 is smaller than the magnetic force of the magnet of the refrigerating chamber door 420.

    [0093] Each of the side surfaces of the refrigerating chamber door 420 and the freezing chamber door 440 is formed with door grooves 424 and 444 for providing handles.

    [0094] Therefore, when the freezing chamber door 420 is pulled in the state where the user's hand puts in the door home 424 of the refrigerating chamber door 420, the refrigerating chamber door 420 is rotated in the state where the freezing chamber door 440 is coupled with the refrigerating chamber door 420, such that the refrigerating chamber 412 is opened.

    [0095] When the refrigerating chamber door 440 is pulled in the state where the user's hand puts in the door home 444 of the freezing chamber door 440, the magnetic force of the magnet of the refrigerating chamber door 420 is larger than the magnetic force of the magnet of the freezing chamber door 440, such that only the freezing chamber door 440 is rotated in the state where the refrigerating chamber door 420 is coupled with the main body to open the freezing chamber 414.

    [0096] With the above-mentioned example, the refrigerating chamber 412 is formed in the entire space of the main body 410 and the freezing chamber 414 formed at the freezing chamber door 440 can be positioned inside the refrigerating chamber 412, such that the volume of the refrigerating chamber 412 can be formed as large as possible.

    [0097] Unlike this, in order to make the volume of the freezing chamber large, the freezing chamber can be formed at the main body and the refrigerating chamber can be formed at the door. In this case, the refrigerating chamber is formed at the freezing chamber door and the refrigerating chamber is positioned at the front of the freezing chamber door.

    [0098] In the description above, the freezing chamber or the refrigerating chamber formed at the main body is referred to as the first storage chamber and the refrigerating chamber or the freezing chamber, which is selectively received in the first storage chamber by the housing provided at the main body, is referred to as the second storage chamber. Thereby, the first storage chamber and the second storage chamber are the refrigerating chamber or the freezing chamber and any one thereof may be the refrigerating chamber or the other thereof may be the freezing chamber.
