As illustrated in the drawings, a refrigerator 1 according to a first embodiment may include a cabinet 10 in which a storage space is defined, and a door that opens and closes the storage space.

For example, the storage space may be divided vertically, and a refrigerating compartment 11 may be provided at an upper side, and a freezing compartment 12 may be provided at a lower side. Each of the refrigerating compartment 11 and the freezing compartment 12 may be maintained at a set temperature by supplying cold air generated by an evaporator 14. As an example, the evaporator 14 may be provided in the freezing compartment 12, and the cold air may be supplied to the refrigerating compartment 11 and the freezing compartment 12 by driving a blowing fan 16 provided in the freezing compartment 12.

In addition, the cabinet 10 may be provided with a cabinet duct 15 that supplies the cold air to the ice-making chamber 50, which will be described below. The cabinet duct 15 may be provided to guide a flow of the cold air between the evaporator 14 and the refrigerating compartment door 21 in which the ice-making chamber 50 is provided. Then, in a state in which the refrigerating compartment door 21 is closed, the refrigerating compartment door 21 may communicate with the ice-making chamber 50 to guide the cold air generated in the evaporator 14 to the ice-making chamber 50, and air that is heat-exchanged in the ice-making chamber 50 may be collected again toward the evaporator 14.

As another example, the evaporator may be provided in each of the refrigerating compartment 11 and the freezing compartment 12, and the cabinet duct 15 may be configured so that one side of the refrigerating compartment 11, in which the evaporator is disposed, communicates with the ice-making chamber 50.

The door 20 may include a refrigerating compartment door 21 that opens and closes the refrigerating compartment 11 and a freezing compartment door 22 that opens and closes the freezing compartment 12. A pair of the refrigerating compartment door 21 and the freezing compartment door 22 may be provided at each of both left and right sides to open and close the refrigerating compartment 11 or the freezing compartment 12.

At least one of the doors 20 may have a double door structure constituted by a first door 40 and a second door 30. The first door 40 may be called an inner door, and the second door 30 may be called an outer door. In addition to the refrigerator 1 having the structure provided as an example, the door may be applied to various types of refrigerators having the double door structure. As another example, the present disclosure may be applied to a refrigerator having a structure in which a refrigerating compartment and a freezing compartment are disposed at left and right sides and a refrigerator having a structure in which a freezing compartment is provided at a lower side, and a refrigerating compartment is provided at an upper side.

Upper and lower ends of the first door 40 may be axially coupled to the cabinet 10 by a hinge device. Thus, the first door 40 may be rotatably mounted on the cabinet 10.

Here, the rear surface of the second door 30 may be a rear surface of the panel assembly 32 or the plate 324. In addition, the door storage portion 42 may be cooled by the cold air supplied therein.

The refrigerating compartment 11 and the door storage portion 42 may communicate with each other through the supply duct 451 and the discharge duct 452, and the forced circulation of cold air may be enabled by the storage portion fan 455. Thus, the refrigerating compartment 11 and the door storage portion 42 may be maintained at the same temperature. In addition, a temperature of the door storage portion 42 may be controlled by driving the storage portion fan 455. Here, the temperature of the door storage portion 42 may be higher than that of the refrigerating compartment 11.

In addition to the foregoing embodiment, various embodiments may be exemplified. Hereinafter, another embodiment of the present disclosure will be described in detail with reference to the drawings. In addition, since configurations that are not described below are the same as those of the above-described embodiments, detailed descriptions and illustrations thereof will be omitted to prevent duplication of description, and the same reference numerals will be used for description. In addition, configurations that are not shown may refer to the above-described embodiments. That is, hereinafter, only the configurations that are different from those of the above-described embodiment will be described in detail.

FIG. 9 is a view illustrating an arrangement of a cold air passage of a first door according to a second embodiment. In addition, FIG. 10 is a cross-sectional view taken along line A-A of FIG. 1 according to the second embodiment.

As illustrated in the drawings, in a refrigerator 1 according to a second embodiment, a first door 40c may be provided with an ice-making chamber supply duct 551 and an ice-making chamber return duct 552, and thus, cold air of an evaporator 14 may be supplied to an ice-making chamber 50 to cool the ice-making chamber 50, thereby performing an ice-making operation.

In addition, an insulating material 413 may be filled into a first door 40c, and the ice-making chamber may be surrounded by the insulating material 413. Thus, the door storage portion 42 and the ice-making chamber 50 may be separated from each other by the insulating material 413 and thus be insulated from each other.

The first door 40c may be provided with a supply duct 451. The supply duct 451 may be provided at an upper portion of the first door 40c to allow a door storage portion 42 to communicate with a refrigerating compartment 11. The supply duct 451 may be provided to pass through front and rear surfaces of the first door 40. The supply duct 451 may be opened at an upper portion of the door storage portion 42 and may form an inlet 453. Thus, cold air inside the refrigerating compartment 11 may be supplied to the door storage portion 42 through the supply duct 451 and the inlet 453.

A storage portion fan 455 may be further provided in the supply duct 451. The cold air in the refrigerating compartment 11 may be forcibly supplied to the door storage portion 42 by driving the storage portion fan 455.

A through-portion 456 passing through the first door 40c in a front and rear direction may be provided at a lower portion of the first door 40c. The through-portion 456 may pass through most of the lower portion of the first door 40c, except for the door storage portion 42 and a display 435.

The door storage portion 42 and the refrigerating compartment 11 may communicate with each other through the through-portion 456. Therefore, the cold air introduced into the door storage portion 42 through the inlet 453 may flow downward of the door storage portion 42 and then be discharged to the refrigerating compartment 11 through the through-portion 456 disposed at the lower portion of the first door 40c. Thus, the refrigerating compartment 11 and the door storage portion 42 may communicate with each other and thus be maintained at the same temperature.

The first door 40c may include a dispenser 43c. The dispenser 43c may be configured to dispense ice made in an ice-making chamber 50 or purified water and may be provided in the through-portion 456.

The dispenser 43c may be provided on a top surface of the through-portion 456. The dispenser 43 may include an ice dispensing portion 432 and a water dispensing portion 433. The ice dispensing portion 432 may communicate with the ice-making chamber 50, and ice inside the ice-making chamber 50 may be discharged. The ice dispensing portion 432 may be disposed on the top surface of the through-portion 456. In addition, the water dispensing portion 433 may be disposed adjacent to the ice dispensing portion 432 and may be disposed on the top surface of the through-portion 456.

The dispenser 43c may include a manipulation member 434c. The manipulation member 434c may have a lever-like structure and may be provided on the top surface of the through-portion 456. The manipulation member 434c may be provided on the ice dispensing portion 432. The ice dispensing portion 432 or the water dispensing portion 433 may be opened and closed by manipulating the manipulation member 434c to discharge ice or water. The manipulation member 434c may have various structures that recognize user manipulation such as a button, a switch, and a touch sensor.

The manipulation member 434c may be manipulated in a vertical direction and may not substantially occupy an internal space of the through-portion 456. In addition, since the manipulation member 434c is disposed adjacent to the ice dispensing portion 432, the manipulation member 434 may be manipulated through an intuitive operation of bringing a cup or container toward the ice dispensing portion 432. In addition, the manipulation member 434c may be manipulated while bringing the cup or container close to the ice dispensing portion 432 to prevent water or ice from being scattered and more easily confirm the dispensing of the water or ice.

The through-portion 456 may extend from the ice dispensing portion 432 up to a lower end of the first door 40c. In addition, the remaining horizontal portion excluding the left and right ends of the first door 40c may be opened. Thus, access to the inside of the refrigerating compartment 11 may be possible through the through-portion 456.

A storage member 457 such as a separate door basket may be disposed inside the through-portion 456. That is, the storage member 457 in which food is stored may be disposed on an inner bottom surface of the through-portion 456. The through-portion 456 may provide a separate storage space in the first door 40c. Thus, the door storage portion 42 may be referred to as a first door storage portion 42, and the through-portion 456 may be referred to as a second door storage portion. In addition, when an entire recessed space of the first door 40c shielded by the second door 30 is referred to as the door storage portion 42, the through-portion 456 may be referred to as a portion of the door storage portion 42.

A lower portion of the first door 40c may be opened in the front and rear direction due to the through-portion 456, and since the ice-making chamber 50 is disposed at the upper portion of the first door 40c, a space in which a filter 442c and a water tank 441c are disposed may not be secured. Thus, the water tank 441c and the filter 442c for supplying water to the dispenser 43 and the ice maker 53 may be provided in a cabinet 10. In addition, a tube 44 connected to the water tank 441c and the filter 442c may be introduced into the first door 40 through a hinge device 131 and may be branched from the valve 443c inside the first door 40 and be connected to the dispenser 43 and the ice maker 53.

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 456. The second door 30 may include a transparent panel assembly 32, and a see-through portion 321 may be provided. Therefore, even when the second door 30 is closed, when the door light 46 is turned on, the door storage portion 42 and the through-portion 456 may be visible through the see-through portion 321.

In some examples, the second door 30 may not include the panel assembly 32. The second door 30 may be configured so that an insulating material is entirely filled into the second door as illustrated in FIG. 12, and the door accommodation portion 42 is not seen from the outside.

The first door 40d may be provided with an ice-making chamber supply duct 551 and an ice-making chamber return duct 552. The cold air may be supplied to the ice-making chamber 50 through the ice-making chamber cold air inlet 553 disposed on one end of the ice-making chamber supply duct 551 so that the ice-making chamber 50 is cooled, and an ice-making operation of the ice maker 53 is performed. In addition, air in the ice-making chamber 50 may be collected toward an evaporator 14 through the ice-making chamber cold air outlet 554 disposed at one end of the ice-making chamber return duct 552.

In addition, an insulating material 413 may be filled into a first door 40d, and the ice-making chamber may be surrounded by the insulating material 413. Thus, the door storage portion 42 and the ice-making chamber 50 may be separated from each other by the insulating material 413 and thus be insulated from each other.

The first door 40d may be provided with a supply duct 451. The supply duct 451 may be provided at an upper portion of the first door 40d to allow a door storage portion 42 to communicate with a refrigerating compartment 11.

The supply duct 451 may be provided to pass through front and rear surfaces of the first door 40d. The supply duct 451 may be opened at an upper portion of the door storage portion 42 and may form an inlet 453. Thus, cold air inside the refrigerating compartment 11 may be supplied to the door storage portion 42 through the supply duct 451 and the inlet 453. In addition, the supply duct 451 may be disposed higher than the ice-making chamber 50.

The supply duct 451 may be provided with a storage portion fan 455 to forcibly supply the cold air from the refrigerating compartment 11 to the door storage portion 42. In addition, air introduced into the door storage portion 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.

The dispenser 43 may be provided in the first door 40d. The dispenser 43 may be provided below the ice-making chamber 50 to communicate with the ice-making chamber 50.

In addition, a manipulation member 434 may be provided in the dispenser recess portion 431d to manipulate a dispensing operation for water or ice.

A manipulation member mounting portion 436 may be disposed in the dispenser recess portion 431. The manipulation member mounting portion 436 may be disposed behind the manipulation member 434. In addition, the manipulation member mounting portion 436 may extend upward to be spaced apart from a bottom surface of the dispenser recess portion 431d. In addition, the manipulation member mounting portion 436 may extend to a position at which at least portion of the manipulation member 434 overlaps, to ensure the mounting and operation of the manipulation member 434.

In addition, a filter 442, a water tank 441, and a valve 443 may be provided on the rear surface of the first door 40d corresponding to the manipulation member mounting portion 436. Thus, water supplied from the outside may be stored in the water tank 441 after passing through the filter 442 and may be selectively supplied to the dispenser 43 and the ice maker 53 by the operation of the valve 443.

A through-portion 456 passing through the first door 40c in the front and rear direction may be provided at a lower portion of the first door 40c. The through-portion 456d may be defined inside the display recess portion 431d. In addition, the through-portion 456d may be defined below the manipulation member mounting portion 436. For example, the through-portion 456d may be defined by a bottom surface of the manipulation member mounting portion 436 in the bottom surface of the dispenser recess portion 431d.

The door storage portion 42 and the storage space 11 may communicate with each other through the through-portion 456. Therefore, the cold air introduced into the door storage portion 42 through the inlet 453 may flow downward of the door storage portion 42 and then be discharged to the storage space 11 through the through-portion 456. Thus, the storage space 11 and the door storage portion 42 may communicate with each other and thus be maintained at the same temperature. The storage space 11 may be a refrigerating compartment.

The through-portion 456d may extend from the manipulation member mounting portion 436 up to a lower end of the first door 40c. In addition, the remaining horizontal portion excluding the left and right ends of the first door 40c may be opened. Thus, access to the inside of the refrigerating compartment 11 may be possible through the through-portion 456d.

A storage member 457 such as a separate door basket may be disposed inside the through-portion 456d. That is, the storage member 457 in which food is stored may be disposed on an inner bottom surface of the through-portion 456d. The through-portion 456 may provide a separate storage space in the first door 40c. Thus, the door storage portion 42 may be referred to as a first door storage portion 42, and the through-portion 456d may be referred to as a second door storage portion. In addition, when an entire recessed space of the first door 40d shielded by the second door 30 is referred to as the door storage portion 42, the through-portion 456d may be referred to as a portion of the door storage portion 42.

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

A display 435 may be further provided on the first door 40.
