[0055] Hereinafter, specific embodiments will be described in detail with reference to the accompanying drawings. However, the scope of the present disclosure is not limited to the embodiments proposed by the present invention, and other inventive concepts or other embodiments included within the spirit of the present disclosure can be easily proposed by adding, changing, deleting other elements, etc.

[0056] When describing the elements of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish one component from another component, and do not limit the component to the nature, order, sequence, etc. of the component. It should be understood that when an element is described as "connected", "coupled", or "joined" to another element, the former may be directly connected or joined to the latter, or may be "connected", "coupled", or "joined" to the latter through a third component interposed therebetween.

[0057] Before the explanation, the directions will be defined. In the embodiments of the present invention, towards Figure 2The direction of the front surface of the door shown can be defined as the front direction. Based on the front surface of the door, the direction towards the cabinet body can be defined as the rear direction, the direction towards the bottom surface where the refrigerator is installed can be defined as the downward direction, and the direction away from the bottom surface can be defined as the upward direction.

[0058] Figure 1 is a front view of a refrigerator according to a first embodiment of the present invention. In addition, Figure 2 is a front view of the refrigerator with the door open. In addition, Figure 3 is a view illustrating the cold air passage structure of the ice-making chamber of the refrigerator. In addition, Figure 4 is a schematic front view illustrating the second door of the refrigerator.

[0059] As shown in the figure, a refrigerator 1 according to a first embodiment of the present invention includes a cabinet body 10 in which a storage space is defined and a door 20 for opening and closing the storage space.

[0060] For example, the storage space can be vertically partitioned, and a refrigerating chamber 11 can be provided in the upper part, and a freezing chamber 12 can be provided in the lower part. By supplying the cold air generated from the evaporator 14, each of the refrigerating chamber 11 and the freezing chamber 12 can be maintained at a set temperature. For example, the evaporator 14 can be installed in the freezing chamber 12, and the cold air can be supplied to the refrigerating chamber 11 and the freezing chamber 12 by driving a blower fan 15 installed in the freezing chamber 12.

[0061] For example, the blower fan 15 and the multi-duct 16 can be provided above the evaporator 14. The cold air of the evaporator 14 can flow upward along the multi-duct 16 and then be guided to the refrigerating chamber 11 by driving the blower fan 15.

[0062] The multi-duct 16 can be provided in the rear wall of the refrigerating chamber 11. The multi-duct 16 can be covered by the rear wall of the refrigerating chamber 11, so it can not be exposed to the outside. In addition, a cold air discharge port 161 communicating with the multi-duct 16 can be provided in the rear wall of the refrigerating chamber 11. A plurality of cold air discharge ports 161 can be provided. Therefore, the cold air generated in the evaporator 14 can flow along the multi-duct 16 and then be evenly discharged into the refrigerating chamber 11 through the cold air discharge ports 161.

[0063] The cold air inside the refrigerating chamber 11 discharged from the cold air discharge port 161 can be supplied to a door storage part 42 provided in the refrigerating chamber door 21 through a supply duct 451 opened on the rear surface of the refrigerating chamber door 21. In addition, the air inside the door storage part 42 can be discharged into the refrigerating chamber 11 through a discharge duct 452 provided on the rear surface of the refrigerating chamber door 21.

[0064] The opening of the supply pipe 451 exposed to the rear surface of the first door 40 may be provided at a position offset from the center of the first door 40 to a side away from the rotation axis of the first door 40. Therefore, even when the first door 40 is closed, the rear end of the opening of the supply pipe 451 is not covered by the ice making chamber 50. Accordingly, when the first door 40 is closed, the cold air in the refrigerating chamber 11 can be smoothly introduced into the door storage part 42.

[0065] An ice making chamber 50 may be provided in the refrigerating chamber 11. The ice making chamber 50 defines a space for manufacturing and storing ice, and may define a space thermally insulated from the refrigerating chamber 11. In addition, a space for accommodating an ice maker (see reference numeral 53 in Figure 6 the drawings) may be defined inside the ice making chamber 50. For example, the ice making chamber 50 may be provided on one side of an edge defined by the top surface and the side surface of the refrigerating chamber 11. In addition, the ice making chamber 50 may extend forward from the rear surface of the refrigerating chamber 11 and extend to communicate with the ice chute 414 of the refrigerating chamber door 21 when the refrigerating chamber door 21 is closed.

[0066] For example, an ice discharging port 511 may be provided on the bottom surface of the ice making chamber 50, and the ice discharging port 511 may communicate with the ice chute 414 when the refrigerating chamber door is closed. Accordingly, the ice in the ice making chamber 50 can be guided to the dispenser 43 through the ice discharging port 511 and the ice chute 414.

[0067] The ice making chamber 50 may be cooled by cold air supplied from the evaporator 14. To this end, the cabinet 10 may be provided with an ice making chamber pipe 55 that communicates with the ice making chamber 50 to supply cold air for the ice making operation. The ice making chamber pipe 55 may include an ice making chamber supply pipe 551 that supplies cold air to the ice making chamber 50 and an ice making chamber return pipe 552 that discharges the air in the ice making chamber 50 toward the evaporator 14.

[0068] One end of the ice making chamber supply pipe 551 may be provided with a supply pipe inlet 551a that communicates with the space in which the evaporator 14 is provided, and the other end of the ice making chamber supply pipe 551 may be provided with a supply pipe outlet 551b that communicates with the rear surface of the ice making chamber 50. In addition, one end of the ice making chamber return pipe 552 may be provided with a return pipe inlet 552a that communicates with the rear surface of the ice making chamber 50, and the other end of the ice making chamber return pipe 552 may be provided with a return pipe outlet 552b that communicates with the space in which the evaporator 14 is accommodated.

[0069] Accordingly, the cold air generated in the evaporator 14 can be supplied to the ice-making chamber 50 through the ice-making chamber supply duct 551, and the air that has undergone heat exchange for ice-making inside the ice-making chamber 50 can be collected toward the evaporator 14 through the ice-making chamber return duct 552. Accordingly, the interior of the ice-making chamber 50 can be maintained at a temperature suitable for the ice-making operation. The evaporator 14 can be provided in each of the refrigerating chamber 11 and the freezing chamber 12, and the ice-making chamber 50 can communicate with the space in which one of the evaporators is provided.

[0070] The door 20 may include a refrigerating chamber door 21 that opens and closes the refrigerating chamber 11 and a freezing chamber door 22 that opens and closes the freezing chamber 12. The refrigerating chamber door 21 and the freezing chamber door 22 may be provided in pairs on each of the left and right sides and may open and close the refrigerating chamber 11 or the freezing chamber 12.

[0071] At least one of the doors 20 may have a double-door structure composed of a first door 40 and a second door 30. The first door 40 may be referred to as an inner door, and the second door 30 may be referred to as an outer door. In addition to the refrigerator 1 having the exemplary structure, the present invention can also be applied to various types of refrigerators having a double-door structure. As another example, the present invention can be applied to a refrigerator having a structure in which the refrigerating chamber door and the freezing chamber door are provided on the left and right sides, and as yet another example, the present invention can be applied to a refrigerator having a structure in which the freezing chamber is provided on the lower side and the refrigerating chamber is provided on the upper side.

[0072] The upper end and the lower end of the first door 40 may be axially coupled to the cabinet 10 through hinge devices. Accordingly, the first door 40 can be rotatably mounted on the cabinet 10. In addition, the first door 40 can open and close the refrigerating chamber 11 by rotation. In addition, the second door 30 can be rotatably mounted on the first door 40. The second door 30 may be provided in front of the first door 40 and may shield the front surface of the first door 40 by rotation.

[0073] The first door 40 may be provided with a door storage unit 42 and a dispenser 43 on its front surface. The door storage unit 42 may be provided in the upper part of the first door 40, and the dispenser 43 may be provided in the lower part of the first door 40. In addition, an ice chute 414 may be provided on the rear surface of the first door 40. The ice chute may provide a passage 415 that passes through the second door 40 to guide ice from the ice-making chamber 50 to the dispenser 43. The entrance 416 of the opening of the ice chute may open to the rear surface of the first door 40, and the other end of the opening of the ice chute 414 may communicate with the ice dispensing unit 433.

[0074] In a state where the first door 40 is closed, the ice tank 414 can protrude rearward to be disposed below the ice making chamber 50. In addition, in a state where the first door 40 is closed, the ice discharge port 511 and the inlet 416 of the ice tank 414 can communicate with each other. Therefore, the ice inside the ice making chamber 50 provided in the cabinet 10 can be distributed to the outside of the first door 40 via the ice tank 414 through the dispenser 43.

[0075] When the door storage part 42 and the dispenser 43 are provided in the first door 40, the second door 30 can shield the door storage part 42 and the dispenser 43. That is, when the second door 30 is closed, the door storage part 42 and the dispenser 43 are not visible. Therefore, the second door 30 can present a simple and tidy appearance. Here, when the second door 30 is opened, food can be assisted in being accommodated through the door storage part 42, and water or ice can be distributed through the dispenser 43. Therefore, the refrigerator 1 can satisfy both the improvement in appearance and the improvement in usability.

[0076] Even when the second door 30 is closed, the rear side of the second door 30, that is, the door storage part 42, can be seen through the second door 30. The observation part 321 allowing the rear side to be observed can be provided on at least a part of the front surface of the second door 30. When the door storage part 42 and the dispenser 43 described below are provided in the first door 40, the door storage part 42 and the dispenser 43 can be observed through the observation part 321 without opening the second door 30. The observation part 321 can be provided by the panel assembly 32 defining the front surface of the second door 30.

[0077] Such a double-door structure can be applied to the refrigerator compartment door 21. In addition, all pairs of refrigerator compartment doors 21 can have a double-door structure.

[0078] For example, the refrigerator compartment door 21 can be composed of a left door 21a and a right door 21b. In addition, the left door 21a can be composed of a first door 40 and a second door 30. In addition, the ice making chamber 50 can be provided on the rear surface of the first door 40, and the door storage part 42 and the dispenser 43 can be provided on the front surface of the first door 40. In addition, the second door 30 can open and close the door storage part 42 and the dispenser 43.

[0079] The right door 21b can be composed of a first door 40b and a second door 30b. In addition, the door storage part 42b can be provided in the first door 40b. In addition, the second door 30b can open and close the door storage part 42b.

[0080] Here, the door storage part 42b of the right door 21b may have a structure with a longer vertical length and a deeper recess than the door storage part 42 of the left door 21a. In addition, the observation parts 321 and 321b may be respectively provided on the second doors 30 and 30b on the left and right sides. Therefore, even when the second doors 30 and 30b are respectively closed, the door storage parts 42 and 42b and the dispenser 43 on the left and right sides can be observed through the observation parts 321 and 321b.

[0081] The ice making chamber 50 and the dispenser 43 may be provided in one of the left door 21a and the right door 21b. Hereinafter, the structure in which the door storage part 42 and the dispenser 43 are provided in the left door 21a of the refrigerating chamber door 21 will be described in more detail with reference to the drawings. Hereinafter, for convenience of description, the left door 21a may be referred to as the refrigerating chamber door 21.

[0082] Figure 5 is a perspective view of the refrigerating chamber door when the second door is open as viewed from one side. In addition, Figure 6 is along Figure 1 the sectional view taken along line A1-A1 in. In addition, Figure 7 is along Figure 1 the sectional view taken along line A2-A2 in.

[0083] As shown in the figure, the door storage part 42 may be provided in the front surface of the first door 40. The door storage part 42 may be recessed into the front surface of the first door 40. The door storage part 42 may be referred to as a door storage space. The door storage part 42 may be provided with a plurality of accommodating members 421. For example, the accommodating member 421 may be a basket. The door storage part 42 may be recessed into the rear surface of the second door 30, and the accommodating member 421 may be provided in the second door 30. In addition, the door storage part 42 may be provided by recessing both the first door 40 and the second door 30. That is, the door storage part 42 may be defined as the space between the first door 40 and the second door 30, which is defined when the second door 30 is closed.

[0084] The first door 40 may include a door body 41 filled with a heat insulating material 413. The door body 41 may include a door housing 411 defining the front surface and a door gasket 412 defining the rear surface. In addition, the forwardly opening door storage part 42 may be provided in the door housing 411. In addition, the door gasket 412 may project rearward to provide an ice trough 414.

[0085] In addition, cold air may be supplied to the door storage part 42. For example, the door storage part 42 may communicate with the refrigerating chamber 11, and the cold air of the refrigerating chamber 11 may be supplied.

[0086] For example, the first door 40 may include a supply duct 451 and a discharge duct 452. The refrigerating chamber 11 and the door storage section 42 may communicate with each other through the supply duct 451 and the discharge duct 452, and the door storage section 42 may be cooled to a set temperature by the circulation of cold air. Here, the temperature of the door storage section 42 may be the same as that of the refrigerating chamber 11.

[0087] The supply duct 451 may be provided at the upper part of the first door 40 and may be arranged to communicate the door storage section 42 and the refrigerating chamber 11 with each other. The supply duct 451 may be arranged to pass through the front surface and the rear surface of the first door 40. Here, the opening of the supply duct 451 may be defined such that it is not covered by the front surface of the ice-making chamber 50 when the first door 40 is closed. Therefore, even when the first door 40 is closed and the ice chute 414 communicates with the ice-making chamber 50, the cold air in the refrigerating chamber 11 can be supplied to the door storage section 42 through the supply duct 451. For example, the opening of the supply duct 451 exposed on the rear surface of the first door 40 may be arranged not to overlap with the front surface of the ice-making chamber 50.

[0088] The supply duct 451 may open upward to the door storage section 42 to provide an inlet 453. The inlet 453 may be provided at the upper end or the top surface of the door storage section 42. In addition, the inlet 453 may extend in the left-right direction of the door storage section 42. Therefore, the cold air in the refrigerating chamber 11 (which is introduced through the supply duct 451) can be supplied from the upper end of the door storage section 42 through the inlet 453.

[0089] The discharge duct 452 may open downward to the first door 40 and may be configured to communicate the door storage section 42 and the refrigerating chamber 11 with each other. The discharge duct 452 may be arranged to pass through the front surface and the rear surface of the first door 40.

[0090] The discharge duct 452 may open downward to the door storage section 42 to provide an outlet 454. The outlet 454 may be provided at the lower end of the door storage section 42. The outlet 454 may extend in the left-right direction of the door storage section 42. Therefore, the air in the door storage section 42 (which is discharged through the outlet 454 and the discharge duct 452) can be discharged into the refrigerating chamber 11. The outlet 454 may be provided in the dispenser recess 431.

[0091] The first door 40 may be provided with a housing fan 455. The housing fan 455 may force the cold air in the refrigerating chamber 11 to be supplied to the door storage section 42. The housing fan 455 may be provided in the supply duct 451 or the discharge duct 452. Alternatively, the housing fan 455 may be provided in both the supply duct 451 and the discharge duct 452.

[0092] Due to the operation of the accommodation unit fan 455, the cold air in the refrigerating chamber 11 can be forcedly supplied to the door storage unit 42, and the cold air introduced into the door storage unit 42 can flow along the rear surface of the second door 30. Here, the rear surface of the second door 30 can be the rear surface of the panel assembly 32 or the plate 324. Therefore, the door storage unit 42 can be cooled by the cold air supplied to its interior.

[0093] The refrigerating chamber 11 and the door storage unit 42 can be communicated with each other through a supply pipe 451 and a discharge pipe 452, and the forced circulation of the cold air can be achieved by the accommodation unit fan 455. Therefore, the refrigerating chamber 11 and the door storage unit 42 can be maintained at the same temperature. In addition, the temperature of the door storage unit 42 can be controlled according to the operation of the accommodation unit fan 455. Here, the temperature of the door storage unit 42 can be higher than the temperature of the refrigerating chamber 11.

[0094] The dispenser 43 can be provided at the lower part of the first door 40. The door storage unit 42 can be provided at the upper part of the first door 40, and the dispenser 43 can be provided at the lower part of the door storage unit 42.

[0095] The door storage unit 42 can be provided in front of the ice making chamber 50 and can at least partially overlap with the ice making chamber 50. In addition, the dispenser 43 can be provided below the ice making chamber 50.

[0096] When the first door 40 is closed, the dispenser 43 can be communicated with the ice making chamber 50, and the ice inside the ice making chamber 50 can be dispensed through the dispenser 43. In addition, the purified water can be drawn through the dispenser 43. For this purpose, the dispenser 43 can include a water dispensing part 433 and an ice dispensing part 432.

[0097] Specifically, the dispenser 43 can include a dispenser recess 431 recessed from the front surface of the first door 40. The dispenser recess 431 can be provided below the water dispensing part 433 and the ice dispensing part 432. In addition, an operating member 434 for operating the water or ice dispensing part can be provided in the dispenser recess 431. The dispenser recess 431 can be a part of the door storage unit 42.

[0098] The user can operate the operating member 434 while placing a cup or a container in the dispenser recess 431 to dispense water or ice through the water dispensing part 433 and the ice dispensing part 432.

[0099] In addition, the dispenser 43 can be shielded by the second door 30. In addition, the dispenser 43 can be selectively visible through the transparent panel assembly 32.

[0100] The first door 40 may be provided with a water tank 441 and a valve 443. The water tank 441 may store water to be supplied to the ice maker. In addition, the valve 443 may be connected to the water tank 441 and may be operated to selectively supply water to the ice maker 53.

[0101] The water tank 441 and the valve 443 may be provided at the lower part of the first door 40 and may be provided at the rear side of the dispenser recess 431. The positions of the water tank 441 and the valve 443 may vary according to the layout of the path of the water supplied to the ice maker 53 and the dispenser 43.

[0102] The first door 40 may be further provided with a display 435. The display 435 may display the operating state of the refrigerator 1 including the dispenser 43. The display 435 may be provided above the dispenser 43. The display 435 may be provided between the door storage part 42 and the dispenser 43. The display 435 may also cover a part of the dispenser 43. The water dispensing part 433 and the ice dispensing part 432 may be provided on the bottom surface of the display 435. In addition, the display 435 may be covered by the second door 30. In addition, the display 435 may be selectively visible through the panel assembly 32.

[0103] The door storage part 42 may be recessed into the front surface of the first door 40. In addition, the door storage part 42 may be defined as the entire opening space in the front surface of the first door 40 (the space is opened and closed by the second door 30).

[0104] In this case, at least one of the accommodation member 421, the dispenser 43, and the display 435 may be provided inside the door storage part 42. Here, the door storage part 42 may be separated by the heat insulation material 413 inside the first door 40 to define an independent space.

[0105] In the state where the second door 30 is closed, the second door 30 may define the front surface of the refrigerating chamber door 21. In addition, the second door 30 may cover the door storage part 42, the dispenser 43, and the display 435 of the first door 40.

[0106] The second door 30 may include a door frame 31 defining a periphery and a panel assembly 32 mounted on the door frame 31. The door frame 31 may have an opening penetrating to communicate with the door storage part, and the panel assembly 32 may cover the opening. In addition, the inside of the door frame 31 provided along the periphery of the panel assembly 32 may be filled with a heat insulation material 311.

[0107] In addition, the panel assembly 32 may overlap at least a part of the door storage part 42. In addition, the panel assembly 32 may overlap at least a part of the door storage part 42 and the display 435.

[0108] For example, the panel assembly 32 can be set to be composed of a plurality of transparent plates 322, 323, and 324. For example, the transparent plates 322, 323, and 324 can be made of tempered glass or insulating glass, and can be spaced apart from each other in the front-rear direction. In addition, the first door 40 can be provided with a door lamp 46 for illuminating the door storage portion 42. The rear side of the second door 30 can be brightened according to the on / off of the door lamp 46 and can be visible through the observation portion 321. The door lamp 46 can be provided inside the door storage portion 42. In addition, the door lamp 46 can be provided on the second door 30. The door lamp 46 can be turned on and off by user manipulation or by detecting the approach of the user.

[0109] Therefore, when the door lamp 46 is turned on, the door storage portion 42 and the dispenser 43 can be observed from the outside through the observation portion 321. In addition, when the display 435 is turned on, the state of the display 435 can be viewed through the observation portion 321.

[0110] For example, a transparent display can be provided between the plurality of transparent plates 322, 323, and 324 to output a screen. Therefore, both the observation of the door storage portion 42 and the screen display can be achieved through the second door 30. Here, the transparent display can be provided only on one side of the refrigerating chamber doors 21 on the left and right sides.

[0111] In addition, the second door 30 may not include the panel assembly 32. As shown below Figure 8 The second door 30 can be constructed such that the inside of the second door 30 is completely filled with the heat insulating material 311, and can be set such that the door storage portion 42 is not visible from the outside.

[0112] Hereinafter, with reference to Figure 6 and Figure 7 the operation of the refrigerator having the above structure will be described.

[0113] As shown in the figure, the ice making chamber 50 can be cooled by the cold air supplied from the evaporator 14. The ice making chamber 50 can have an outer surface defined by the ice making chamber main body 51, and the ice making chamber main body 51 can be made of a heat insulating material to insulate the inside of the ice making chamber 50. Therefore, it can not affect the temperature inside the refrigerating chamber 11 and can be cooled to the ice making temperature by the cold air supplied from the evaporator 14.

[0114] The ice maker 53 inside the ice making chamber 50 can perform an ice making operation to make ice and separate the ice downward. The ice maker 53 can be an automatic ice maker having various structures that automatically perform water supply, ice making, and ice separation.

[0115] The ice separated from the ice maker 53 can fall and be stored inside the ice making chamber 50. In addition, a conveying device 54 can be provided below the ice maker 53 to convey the ice separated from the ice maker 53 toward the ice discharge port 511. That is, at least a part of the ice making chamber 50 can be used as an ice storage box for storing and separating the ice made in the ice maker 53.

[0116] When the first door 40 is closed, the ice discharge port 511 can communicate with the inlet 416 of the ice chute 414. Therefore, the ice discharged from the ice making chamber 50 can be supplied to the dispenser 43 through the ice chute 414.

[0117] The door storage part 42 can be cooled by the cold air in the refrigerating chamber 11. When the second door 30 is closed, the door storage part 42 can be defined between the rear surface of the second door 30 and the front surface of the first door 40.

[0118] In addition, when the accommodation part fan 455 is driven, the cold air in the refrigerating chamber 11 is supplied to the door storage part 42 through the supply pipe 451. Here, an inlet 453 can be provided at the upper part of the door storage part 42, and the cold air passing through the inlet 453 flows downward along the rear surface of the second door 30 (i.e., the rear surface of the panel assembly 32) and the front surface of the first door 40. In addition, the cold air flowing downward through the door storage part 42 can be discharged into the refrigerating chamber 11 through an outlet 454 provided at the lower end of the dispenser recess 431 and a discharge pipe 452.

[0119] If necessary, a damper for opening and closing the supply pipe 451 or the discharge pipe 452 can be further provided, and the door storage part 42 can be controlled to have a temperature different from that of the refrigerating chamber 11.

[0120] Even when the second door 30 is closed, the user can view the door storage part 42, open the second door storage part 42, and take out the food stored in the door storage part 42. In addition, the user can open the second door 30 to expose the dispenser 43 and operate the operating member 434, so as to distribute the ice in the ice making chamber 50 through the dispenser 43.

[0121] In addition to the above embodiments, various embodiments can be exemplified. Hereinafter, another embodiment of the present invention will be described in detail with reference to the drawings. In addition, since the structures not described below are the same as those in the above embodiments, to avoid redundant description, their detailed description and illustration are omitted, and the same reference numerals are used for description. In addition, the structures not shown can be referred to the above embodiments. That is, only the structures different from the above embodiments will be described in detail below.

[0122] Figure 8 is a cross-sectional view taken along line A1 - A1 in Figure 1 in accordance with the second embodiment of the present invention. In addition, Figure 9is a cross-sectional view taken along line A2-A2 in accordance with a second embodiment of the present invention. As shown, a refrigerator 1c according to a third embodiment of the present invention may include a cabinet 10 and a door 21c that opens and closes a storage space of the cabinet 10. Figure 1 The cabinet 10 may at least include a refrigerating compartment 11. An ice-making compartment 50 may be provided in the refrigerating compartment 11, and an ice maker 53 and a conveying device 54 may be provided inside the ice-making compartment 50. In addition, the ice-making compartment 50 may satisfy the temperature for ice-making operation by supplying cold air from an evaporator 14 via an ice-making compartment pipe 55. In addition, the ice-making compartment 50 may provide a heat-insulated space independent of the refrigerating compartment 11.

[0123] The door 21c may be rotatably mounted on the cabinet 10 and may have a double-door structure. Specifically, the door 21c may include a first door 40c that shields the storage space and a second door 30 provided in front of the first door 40c. The second door 30 may open and close the front surface of the first door 40c by rotation.

[0124] The inside of the first door 40c is filled with a heat-insulating material 413. Thus, the space between the door storage part 42 and the storage space 11 may be separated by the heat-insulating material 413 and insulated from each other.

[0125] The first door 40c may be provided with a supply pipe 451. The supply pipe 451 may be provided at the upper part of the first door 40c and may be arranged such that the door storage part 42 and the refrigerating compartment 11 communicate with each other.

[0126] The supply pipe 451 may pass through the front surface and the rear surface of the first door 40c. The supply pipe 451 may open at the upper part of the door storage part 42 to provide an inlet 453. Thus, the cold air inside the refrigerating compartment 11 may be supplied to the door storage part 42 through the supply pipe 451 and the inlet 453. The supply pipe 451 may be further provided with a receiving part fan 455 to forcibly supply the cold air from the refrigerating compartment 11 to the door storage part 42.

[0127] The open rear end of the supply pipe 451 (the open rear end is exposed to the rear surface of the first door 40c) may be arranged at a position biased to one side as in the above-mentioned first embodiment. Thus, when the first door 40c is closed, the front surface of the ice-making compartment 50 may not cover the open rear end of the supply pipe 451, and when the first door 40c is closed, the cold air in the refrigerating compartment 11 may be smoothly supplied to the door storage part 42.

[0128] In addition, the air introduced into the door storage part 42 through the inlet 453 may flow downward along the front surface of the first door 40d and the rear surface of the second door 30.

[0129]

[0130] ​The first door 40c may be provided with a dispenser 43. The dispenser 43 may be provided below the door storage part 42 and may communicate with an ice chute 414 protruding from the rear surface of the first door 40. In addition, when the first door 40 is closed, an inlet 416 of the ice chute 414 may communicate with an ice discharge port 511 of the ice making chamber 50.

[0131] The dispenser 43 may include a dispenser recess 431c recessed from the front surface of the first door 40.

In addition, the operating member mounting part 436 may extend to a position where at least a part of the operating member mounting part 436 overlaps with the operating member 434 to ensure the installation and operation of the operating member 434.

[0133] In addition, a water tank 441 and a valve 443 may be provided in the rear surface of the first door 40c corresponding to the operating member mounting part 436. In addition, the water stored in the water tank 441 may be selectively supplied to the dispenser 43 and the ice maker 53 by the operation of the valve 443.

[0134] A through hole 456c penetrating the first door 40c in the front-rear direction may be provided in the lower part of the first door 40c. The through hole 456c may be provided inside the display recess 431c. In addition, the through hole 456c may be provided below the operating member mounting part 436. For example, the through hole 456c may be defined in the bottom surface of the dispenser recess 431c through the bottom surface of the operating member mounting part 436.

[0135] The door storage part 42 and the refrigerating chamber 11 may communicate with each other through the through hole 456c. Therefore, the cold air introduced into the door storage part 42 through the inlet 453 may flow downward through the door storage part 42 and then be discharged into the refrigerating chamber 11 through the through hole 456c. Therefore, the refrigerating chamber 11 and the door storage part 42 may communicate with each other and be maintained at the same temperature.

[0136] The through hole 456c may extend from the operating member mounting part 436 to the lower end of the first door 40c. In addition, the through hole 456c may be open at the remaining horizontal part except for the left and right end parts of the first door 40c. Therefore, the inside of the refrigerating chamber 11 may be accessed through the through hole 456c.

[0137] A separate receiving member 457, such as a door basket, may be provided inside the through portion 456c. That is, a receiving member 457 capable of receiving food may be provided on the inner bottom surface of the through portion 456c. The through portion 456 may provide a separate receiving space in the first door 40c. Therefore, the door storage portion 42 may be referred to as the first door storage portion, and the through portion 456c may be referred to as the second door storage portion. In addition, when the entire recessed space of the first door 40c (the space shielded by the second door 30) may be referred to as the door storage portion 42, the through portion 456c may be regarded as a part of the door storage portion 42.

[0138] In addition, the second door 30 may be provided in front of the first door 40c, and the second door 30 may shield the door storage portion 42, the display 435, and the through portion 456c. The second door 30 may include a transparent panel assembly 32, and even when the second door 30 is closed, the door storage portion 42, the display 435, and the through portion 456c may be visible.

[0139] The first door 40c may be further provided with a display 435.

[0140] Figure 10 is a cross-sectional view taken along line A2 - A2 in Figure 1 in accordance with the third embodiment of the present invention.

The door storage unit 42 may be provided at the upper part of the first door 40c. The heat insulation material 413 may be provided inside the first door 40c, and the door storage unit 42 provided at the front side and the refrigerator compartment 50 provided at the rear side may be thermally insulated from each other by the heat insulation material 413. In addition, the dispenser 43 may be provided in the front surface of the first door 40c. The dispenser 43 may be provided at the lower part of the first door 40c.

[0145] The supply pipe 451 passing through the first door 40c may be provided at the upper part of the first door 40c to supply the cold air of the refrigerator compartment 11 to the first door 40c. Here, the open rear end of the supply pipe 451 (the open rear end is exposed to the rear surface of the first door 40c) may be provided at a position offset to one side as in the foregoing first and second embodiments. Therefore, when the first door 40c is closed, the front surface of the ice making chamber 50 may not cover the open rear end of the supply pipe 451, and when the first door 40c is closed, the cold air of the refrigerator compartment 11 may be smoothly supplied to the door storage unit 42.

[0146] The dispenser 43 may be provided below the door storage unit 42 and may communicate with the ice chute 414 protruding from the rear surface of the first door 40. In addition, when the first door 40 is closed, the inlet 416 of the ice chute 414 may communicate with the ice discharge port 511 of the ice making chamber 50.

[0147] In addition, the through portion 456c passing through the first door 40c may be provided at the lower part of the first door 40c, that is, at the dispenser recess 431c. The through portion 456d may communicate with the storage space 11 and may provide a passage for discharging the cold air of the door storage unit 42.

[0148] In addition, the through portion 456c may also be used as an accommodation space. For this purpose, an accommodation member 457 such as a door basket may be provided in the through portion 456c.

The door panel 32 may be made of various materials such as opaque glass, metal, plastic, and composite materials. In addition, the interior of the second door 30d may be filled with a heat insulating material 311. Thus, the door storage section 42 may achieve thermal insulation through the heat insulating material 311. In addition, the cold air introduced into the door storage section 42 may move along the rear side 33 of the second door 30d.

[0151] Thus, the door storage section 42 may be thermally insulated from the refrigerating chamber 11 provided at the rear side through the heat insulating material 413 of the first door 40c, and may also be thermally insulated from the outside air at the front side through the heat insulating material 311 of the second door 30c. Thus, the cold air supplied to the door storage section 42 may flow between the second door 30d and the first door 40c. In addition, the interior of the door storage section 42 may be maintained at a set temperature by the supplied cold air.

[0152] The second door 30d may shield the door storage section 42 when closed, and may also shield the dispenser 43 and the through portion 456c.

[0188] The second door 60 can be set to have a smaller size than the first door 70 and can shield a part of the first door 70. For example, the second door 60 can be disposed above the protrusion 715 and can be rotatably mounted on the first door 70 to open and close the door storage portion 72. When the second door 60 is closed, it can provide the same plane as the front surface of the protrusion 715.

[0189] That is, the second door 60 and the door storage portion 72 can be disposed above the dispenser 73. When the second door 60 is closed, the front surface of the second door 60 can provide the same plane as the front surface of the dispenser 73.

[0190] The upper part of the first door 70 where the second door 60 is provided can be set in a stepped shape. The door storage portion 72 can be disposed in front of the ice making chamber 50 and can at least partially overlap with the area of the ice making chamber 50.

[0191] The first door 70 can include a supply pipe 751 and a discharge pipe 752. The refrigerating chamber 11 and the door storage portion 72 can communicate with each other through the supply pipe 751 and the discharge pipe 752, and the door storage portion 72 can be cooled to a set temperature through the circulation of cold air. Here, the temperature of the door storage portion 72 can be the same as the temperature of the refrigerating chamber 11.

[0192] The supply pipe 751 can be disposed at the upper part of the first door 70 and can be set so that the door storage portion 72 and the refrigerating chamber 11 communicate with each other. The supply pipe 751 can be set to pass through the front surface and the rear surface of the first door 40.

[0193] Here, the opening of the supply pipe 751 can be defined so that it is not covered by the front surface of the ice making chamber 50 when the first door 70 is closed. Therefore, even when the first door 70 is closed and the ice trough 714 communicates with the ice making chamber 50, the cold air in the refrigerating chamber 11 can be supplied to the door storage portion 42 through the supply pipe 751. For example, the opening of the supply pipe 751 exposed on the rear surface of the first door 40 can be set not to overlap with the front surface of the ice making chamber 50.

[0194] The supply pipe 751 can open to the upper part of the door storage portion 72 to provide an inlet 753. The inlet 753 can be disposed at the upper end or the top surface of the door storage portion 72. In addition, the inlet 753 can extend in the left - right direction of the door storage portion 72. Therefore, the cold air in the refrigerating chamber 11 (which is introduced through the supply pipe 751) can be supplied from the upper end of the door storage portion 72 through the inlet 753.

[0195] The discharge duct 752 can be disposed below the supply duct. For example, the discharge duct 752 can be disposed at the lower part of the door storage unit 72 and can provide an outlet 754. The outlet 754 can be disposed in the lower end of the door storage unit 72. In addition, the discharge duct 752 can be configured such that the door storage unit 72 and the refrigerating compartment 11 communicate with each other. The discharge duct 752 can be disposed to pass through the front surface and the rear surface of the first door 70, and thus, the air in the door storage unit 72 can be discharged into the refrigerating compartment 11.

[0196] The discharge duct 752 can be disposed above the dispenser 73. The discharge duct 752 can be disposed between the door storage unit 72 and the dispenser 73. In addition, the discharge duct 752 can extend in a direction intersecting with the ice chute 555 that connects the ice making chamber 50 and the dispenser 73. In addition, the discharge duct 752 can be disposed between the lower ends of the door storage unit 72 and the ice making chamber 50.

[0197] The cold air inside the refrigerating compartment 11 can be supplied to the upper part of the door storage unit 72 through the supply duct 751. In addition, the air flowing toward the lower part of the door storage unit 72 can be discharged into the refrigerating compartment 11 through the discharge duct 752. The accommodation unit fan 755 can be disposed in the supply duct 751 or the discharge duct 752. Thus, the cold air of the refrigerator can be efficiently supplied to the door storage unit 72. In addition, by supplying cold air from the refrigerating compartment 11, the refrigerating compartment 11 and the door storage unit 72 can be maintained at the same temperature.

[0198] The second door 60 can include a door frame 61 that defines the periphery of the second door 60 and a panel assembly 62 mounted at the center of the opening of the door frame 61. The inside of the door frame 61 can be filled with a heat insulating material 611.
