Fig. 1 is a schematic perspective view of a refrigerator 10 in which a storage space is formed on a door 11 according to one embodiment of the present invention. The refrigerator 10 in which the storage space is formed at the door 11 may generally include: a box body 12 and a door body 11.
At least a first storage space (hidden by the door 11, not shown in the drawings) having a forward opening is defined in the cabinet 12. Generally, the cabinet 12 defines therein at least one, and usually a plurality of, storage spaces with open front sides, which may be classified into a refrigerating compartment, a freezing compartment, a temperature-changing compartment, and the like, according to a refrigerating temperature and a function. The number and function of the specific storage compartments can be configured according to pre-determined requirements. The first storage space may define one or more of a plurality of storage spaces for the case 12.
And a door 11 provided in a front side of the cabinet 12 to open and close the storage compartment. For example, the door 11 may be hingedly disposed at one side of the front portion of the cabinet 12 to pivotally open and close the cabinet 12. The door 11 may be arranged according to the layout of the cabinet 12. The layout structure of the cabinet 12 may be configured according to the function and requirement of the refrigerator, and may be set in various forms such as a side-by-side door, a T-shape (cross-split), a french (four-door, multi-door), and the like.
The door body 11 may include: a first door 200 (or referred to as a main door or an inner door) and a second door 110 (or referred to as a front door or an outer door). The first door 200 may be pivotably disposed at a front portion of the forward opening, and may define a second storage space 210 therein. The second door 110 is pivotably provided at a side of the first door 200 away from the cabinet 12, and serves to open and close an opening of the second storage space 210. When the second door 110 is separately opened, the second storage space 210 may be exposed. In addition, the second door 110 may be opened simultaneously with the first door 200, so that the first storage space defined by the case body 12 may be exposed. Since the hinge and the rotating structure of the double-layer door are known per se by those skilled in the art, redundant description is not given in this embodiment.
In the refrigerator 10 of the present embodiment in which the storage space is formed in the door body 11, the first storage space defined by the cabinet 12 has a forward opening, and is closed by a double door (or door-in-door).

In the refrigerator 10 of the present embodiment, the second storage space 210 is relatively independent from the first storage space. When the second door 110 is opened alone, the leakage of the cold of the first storage space can be prevented. In the normal storage process, the odor can be prevented from being mixed between the first storage space and the second storage space 210.
The first door 200 is opened with a blowing port 223 toward one side of the front opening, and the low-temperature gas of the first storage space is introduced into the second storage space 210 by using the blowing port 223 to refrigerate the inside of the second storage space 210. A fan and a sterilization device can be additionally arranged at the air supply opening 223 to meet the refrigeration requirement of the second storage space 210.
The second storage space 210 may be partitioned into a plurality of storage regions. The number and the structure of the storage areas can be set according to the storage requirements. In some embodiments, at least one of the storage regions may be configured as a sealed drawer 300, which sealed drawer 300 may be used to enable dry zone storage, fresh food storage, and the like. The number of the sealed drawers 300 can be one or more, and the specific number can be configured according to the storage requirement.
In the refrigerator 10 of the present embodiment, the second storage space 210 and the first storage space at the rear side may be both configured as a refrigerated storage space. And the storage requirements of different articles are met through partitioning.
