Alternatively, the freezer compartment 12 may be divided in the left-right direction or the up-down direction, and the first freezer door may open and close one divided space, and the second freezer door may open and close the other divided space.

[0090] It should be noted that in the present invention, there is no limitation on the number or arrangement of the refrigerating chamber door 21 and the freezing chamber door 22 .

[0091] When the refrigerator compartment door 21 is a single door, the refrigerator compartment door 21 may include a first door that opens and closes the refrigerator compartment 11 and a second door that can rotate relative to the first door. Alternatively, at least one of the first refrigerator compartment door 100 or the second refrigerator compartment door 101 may include a first door 110, 111 that opens and closes the refrigerator compartment 11 and a second door 200, 201 that can rotate relative to the first door 110, 111.

[0092] As an example, Figure 2 It is shown that each of the first refrigerating compartment door 100 and the second refrigerating compartment door 101 includes a first door 110 , 111 and a second door 200 , 201 .

[0093] The second door 200 of the first refrigerating compartment door 100 may be rotatably connected to the cabinet 10 , or may be rotatably connected to the first door 110 .

[0094] The first door 110 and the second door 200 may form a storage space in which food may be placed.

[0095] When the second door 200 is closed, the storage space may be shielded, and when the second door 200 is opened, the storage space may be opened or exposed to the outside.

[0096] For example, the storage space may be formed by the first door 110. In this case, the storage space may be formed so that the front surface of the first door 110 is recessed toward the cabinet 10 or the rear surface of the first door. Alternatively, the storage space may be formed by the second door 200. In this case, the storage space may be formed so that the rear surface of the second door 200 is recessed toward the front surface. Alternatively, a portion of the storage space may be formed by the first door 110, and another portion may be formed by the second door 200.

[0097] For example, the first door 110 may form a first storage space 124. The second door 200 may form a second storage space 214. When the second door 200 is closed, the first storage space 124 and the second storage space 214 may communicate with each other.

[0098] In this case, the first storage space 124 may be formed such that the front surface of the first door 110 is recessed toward the rear surface of the first door. The second storage space 214 may be formed such that the rear surface of the second door 200 is recessed toward the front surface of the second door.

[0099] Baskets 220 and 221 for supporting food can be positioned in the storage spaces 124 and 214. The baskets 220 and 221 can be installed in the second door 200, for example. A portion of the baskets 220 and 221 can be located in the second storage space 214. When the second door 200 is closed, the other portion of the baskets 220 and 221 can be accommodated in the first storage space 124.

[0100] According to this embodiment, while first door 110 is closed, the user can access baskets 220, 221 by opening second door 200. This advantageously allows the user to easily access baskets 220, 221 without opening the heavy first door 110. Furthermore, since baskets 220, 221 can be accessed without opening first door 100, the cool air in refrigeration compartment 11 can be prevented from being discharged to the outside. Since the cool air can be supplied to storage spaces 124, 214, the food in storage spaces 124, 214 can be kept at a low temperature.

[0101] The first storage space 124 may include a first space 125. The first storage space 124 may further include a second space 126 disposed below the first space 125. The first space 125 may have a recessed depth different from that of the second space 126.

[0102] The baskets 220, 221 may include a first basket 220 located in the first space 125 and a second basket 221 located in the second space 126. The front-to-back length of the first basket 220 may be different from the front-to-back length of the second basket 221.

[0103] The second space 126 may have a recessed depth greater than that of the first space 125. The second space 126 may be, for example, a dispensing space from which water or ice may be dispensed.

[0104] The first door 110 may include a door frame 120. A foamed insulation for heat insulation may be provided inside the door frame 120. Alternatively, the door frame 120 may be insulated using a vacuum insulation.

[0105] The door frame 120 may include a front frame 121. The door frame 120 may further include a door lining 122 directly connected to the front frame 121 or indirectly connected to the front frame 121 through a separate member.

[0106] The front frame 121 may form at least a portion of the first storage space 124. That is, a portion of the front frame 121 may be recessed rearward.

[0107] In one embodiment, the front frame 121 may form a first space 125 and a second space 126 .

[0108] The first door 110 may further include a dispenser 140 for dispensing water or ice. The dispenser 140 may include a dispenser housing 141 to form a dispensing space. In another embodiment, the front frame 121 may form a first space 125 and the dispenser housing 141 may form a second space 126.

[0109] The second door 200 may include a door frame 210. A foamed insulation body for heat insulation may be provided inside the door frame 210. Alternatively, the door frame 210 may be heat-insulated using a vacuum insulation body.

The door lining 212 may form a second storage space 214. Baskets 220 and 221 may be coupled to the door lining 212.

[0111] Since the thickness of the second door 200 is limited, the depth of the second storage space 214 may be smaller than the depth of the first storage space 124 .

[0112] The first door 110 may further include an ice maker 160 to produce ice. The first door 110 may further include an ice making chamber 152 to accommodate the ice maker 160.

[0113] The ice making chamber 152 may be formed such that a portion of the rear surface of the first door 110 is recessed forward or toward the second door 200. The first door 110 may further include an ice making chamber door 154 that opens and closes the ice making chamber 152.

[0114] The first door 110 may further include a receiving portion 155. The receiving portion 155 may receive at least one of a water tank, a filter for purifying water, or a valve for controlling water flow. The receiving portion 155 may be formed by recessing a portion of the rear surface of the first door 110 forward. The receiving portion 155 may be covered by a cover member 156.

[0115] For example, the door liner 122 may form the ice making chamber 152. The door liner 122 may form the receiving portion 155.

[0116] The door liner 122 may include a first portion 122a and a second portion 122b extending rearwardly in a manner protruding from the first portion 122a. For example, the second portion 122b may form the ice making chamber 152 and the receiving portion 155.

[0117] The structure of the second refrigerating chamber door 101 may be the same as or different from that of the first refrigerating chamber door 100. Figure 3 , the structure of the second refrigerating compartment door 101 is shown to be different from that of the first refrigerating compartment door 100 .

[0118] The first door 111 of the second refrigerating compartment door 101 may include an opening 112. The second door 201 of the second refrigerating compartment door 101 may open and close the opening 112.

[0119] The first doors 110 , 111 may be referred to as inner doors or main doors, and the second doors 200 , 201 may be referred to as outer doors or auxiliary doors.

[0120] Figure 5 It is along Figure 1 The cross-sectional view taken along line 5-5 is Figure 6 It is along Figure 1 A cross-sectional view taken along line 6-6.

[0121] Reference Figures 2 to 6 The first door 110 may further include a door cold air duct 40 through which cold air flows. The door cold air duct 40 may include a first duct 410 that guides cold air to the ice making chamber 152. The cold air duct 400 may further include a second duct 420 through which cold air discharged from the ice making chamber 152 flows.

[0122] The ice making chamber 152 may overlap the first storage space 124 in the front-rear direction.

[0123] The first door 110 may include an ice making chamber wall 151 to form an ice making chamber 152. The ice making chamber wall 151 may be spaced apart in the front-to-rear direction from the wall 121a forming the first space 125. A heat insulator may be provided between the wall 121a forming the first space 125 and the ice making chamber wall 151, or a vacuum insulation space may be formed between the wall 121a forming the first space 125 and the ice making chamber wall 151.

[0124] For example, the ice making chamber 152 may overlap the first space 125 in the front-rear direction. Therefore, when the second door 200 is closed, the first basket 220 may be located in front of the ice making chamber 152. The ice making chamber 152 may not overlap the second space 126 in the horizontal direction.

[0125] The receiving portion 155 may overlap the first storage space 124 in the front-rear direction. For example, the receiving portion 155 may overlap the second storage space 126 in the front-rear direction. The water tank 158 and the valve 157 may be located in the receiving portion 155, but are not limited thereto.

[0126] When the second door 200 is closed, the second basket 221 may be accommodated in the second space 126. At least a portion of the second basket 221 may be spaced apart from the dispenser case 141.
