[0081] The door device 100 is mounted on the cabinet assembly of the refrigerator 200, that is, the first side portion 1111 of the first door body 111 is rotatably connected to the cabinet assembly of the refrigerator 200, so that the first door body 111 can rotate relative to the refrigerator 200 around the first side portion 1111. The third side portion 1121 of the second door body 112 is rotatably connected to the second side portion 1112, so that the second door body 112 can rotate relative to the first door body 111 around the second side portion 1112. The ninth side portion of the third door body is rotatably connected to the fourth side portion 1122, so that the third door body rotates relative to the second door body 112.

[0082] When the first door body 111, the second door body 112 and the third door body are arranged side by side in sequence along the first direction, each folding door group 110 of the door device 100 covers the storage chamber of the cabinet assembly, so that the storage chamber of the refrigerator 200 is closed. When the third door body is pulled, the third door body moves in the opposite direction of X, and the third door body rotates around the fourth side portion 1122 toward the second door body 112, so that the third surface is partially attached to the fourth surface, thereby driving the second door body 112 to move in the opposite direction of X, and the second door body 112 rotates around the second side portion 1112 toward the first door body 111, so that the first surface is partially attached to the second surface, and the first door body 111 can rotate around the first side portion 1111 relative to the cabinet assembly of the refrigerator 200, so that the storage chamber of the refrigerator 200 is opened.

[0083] Of course, in other embodiments, the folding door set 110 may also include N door bodies arranged in sequence along the first direction, and two adjacent door bodies can rotate relative to each other. Wherein, N is an integer greater than 3, and along the first direction, the first door body is the first door body 111, and the last door body is the Nth door body.

[0084] When the door bodies are arranged side by side in sequence along the first direction, the folding door groups 110 of the door device 100 cover the storage chamber of the cabinet assembly, so that the storage chamber of the refrigerator 200 is closed. When the Nth door body is pulled, the Nth door body moves in the opposite direction of X, and the Nth door body rotates around its side adjacent to the door body next to it toward the door body next to it, so that the surface of the Nth door body partially fits with the surface of the door body next to it, so that the door bodies are folded and stored in the opposite direction of X, so that the storage chamber of the refrigerator 200 is opened.

[0085] In other embodiments, the box door device 100 may also include two folding door groups 110. Along the first direction, the first folding door group 110 is the first door group, and the second folding door group 110 is the second door group. The first door body 111 and the second door body 112 of the two adjacent folding door groups 110 are rotatably connected.

[0086] When the folding door groups 110 are arranged in parallel in sequence along the first direction, the folding door groups 110 of the cabinet door device 100 cover the storage chamber of the cabinet assembly, so that the storage chamber of the refrigerator 200 is closed. When the Nth door body in the second door group is pulled, the Nth door body moves in the opposite direction of X, and the Nth door body rotates around its side adjacent to the door body next to it toward the door body next to it, so that the surface of the Nth door body is partially attached to the surface of the door body next to it, so that each door body is folded and stored in the opposite direction of X, so that the storage chamber of the refrigerator 200 is opened.

[0087] In other embodiments, the box door device 100 may also include M folding door groups 110. Along the first direction, the first folding door group 110 is the first door group, the last folding door group 110 is the Mth door group, and the first door body 111 and the second door body 112 of two adjacent folding door groups 110 are rotatably connected.

[0088] When the folding door groups 110 are arranged in parallel in sequence along the first direction, the folding door groups 110 of the door device 100 cover the storage chamber of the cabinet assembly, so that the storage chamber of the refrigerator 200 is closed. When the Nth door body in the Mth door group is pulled, the Nth door body moves in the reverse direction X, and the Nth door body rotates around its side adjacent to the door body next to it toward the door body next to it, so that the surface of the Nth door body partially fits with the surface of the door body next to it, so that each door body is folded and stored in the reverse direction X, so that the storage chamber of the refrigerator 200 is opened.

[0089] The utility model also provides a refrigerator 200, including a cabinet assembly and a cabinet door device 100, the cabinet assembly is provided with a storage chamber, the first side portion 1111 of the first door body 111 is rotatably connected to the cabinet assembly, and the third side portion 1121 of the second door body 112 is rotatably connected to the second side portion 1112 of the first door body 111.

[0090] When the door device 100 is in the unfolded state, the folding door set 110 covers the storage room. When the door device 100 is in the folded state, the second door body 112 rotates around the second side portion 1112 toward the first door body 111 so that the first surface is partially attached to the second surface.
