The embodiment of the utility model provides a door body assembly, a freezing/refrigerating chamber and a refrigerator.

The technical solution provided by the present invention will be explained in more detail with reference to fig. 1 to 18.

As shown in fig. 1-18, the present embodiment provides a door assembly, which includes at least two inner doors located inside a compartment door, all of the inner doors can be slidably connected to a door frame 4, and all of the inner doors can seal the compartment when fully unfolded on the door frame 4, and can slide along another inner door adjacent to the inner door when any inner door is pushed or pulled, so as to open or close at least a portion of the compartment when the compartment door is opened.

The compartment may be a freezing compartment 1-2 or a refrigerating compartment 1-1, and referring to fig. 1, the freezing compartment 1-2 in this embodiment is provided with a door and the door assembly located in the door. Referring to fig. 1, the conventional refrigerator includes a freezing compartment 1-2 and a refrigerating compartment 1-1, which are separated by a center sill 2.

The door body assembly of the present embodiment is provided with at least two inner doors in the door of the freezing/refrigerating compartment, and all the inner doors can seal the whole compartment when sliding on the door frame 4 to the fully expanded state, and even when the door of the compartment is opened, the inner doors can prevent cold leakage in the fully expanded state. When different storage spaces in the compartment need to be opened, the corresponding door body can be pushed or pulled to enable the door body to slide on the door frame 4, the corresponding part of the compartment is opened, meanwhile, due to the fact that the adjacent inner doors are in sliding connection, sliding of any inner door is not affected, cold energy can be reduced, the cold energy is dissipated from the inner doors, the space of the compartment, which is opened outwards, is reduced, and energy consumption is reduced.

As an optional implementation manner, the compartment of the embodiment has one or more than two storage spaces, and when all the storage spaces are arranged up and down, all the inner doors can slide up and down on the door frame 4; when all the storage spaces are arranged left and right, all the inner doors can slide left and right on the door frame 4. As shown in fig. 1, the storage space of the freezing compartment 1-2 of fig. 1 is arranged up and down, and thus, all the inner doors in this embodiment can slide up and down.

In the prior art, more than two drawers are usually disposed in the freezing compartment 1-2 and the refrigerating compartment 1-1, storage spaces are formed in the drawers for storing articles, and a user can pull different drawers to take out articles in the corresponding storage spaces from the refrigerator. The drawer only has the function of storing articles in a classified mode, when the door of the chamber is opened, the drawer cannot seal the chamber, in the prior art, the whole space corresponding to the freezing chamber 1-2 or the refrigerating chamber 1-1 is opened outwards only by opening the door of the chamber, and more cold energy is leaked.

In this embodiment, preferably, the inner door is a transparent door, and when the door corresponding to the compartment is opened, as shown in fig. 1, when the door 3 of the freezing compartment is opened, the door assembly seals the freezing compartment 1-2, so as to reduce the loss of cold energy. The user observes the article that wants to take through transparent interior door in which drawer, the interior door that slides corresponds to open the indoor drawer that corresponds in the room, take article, convenient to use has reduced the outdoor open space in room.

Example one

Referring to fig. 1 to 4, 12 and 13, three drawers (storage spaces) are disposed in a freezing compartment 1 to 2 of a common refrigerator, and therefore, in the present embodiment, a door assembly including three inner doors is described as an example with reference to the drawings, but the number of the inner doors is not specifically limited:

the inner door assembly of this embodiment includes first inner door 5, second inner door 6 and third inner door 7, and sliding connection between the adjacent inner door guarantees the smoothness nature of motion and the leakproofness between the adjacent inner door.

As an alternative embodiment, when all the inner doors are completely unfolded on the door frame 4, only one inner door is hermetically fitted to the open side of each storage space in the compartment, and when the inner doors are completely opened and limited to slide by the other inner door, only one storage space is opened.
