Fig. 1 is a schematic side perspective view of a refrigerator 100 according to one embodiment of the present invention. Fig. 2 is a schematic perspective view of the refrigerator 100 shown in fig. 1 when the first drawer 200 and the second drawer 300 are not coupled. Fig. 3 is a schematic perspective view illustrating a first drawer 200 and a second drawer 300 of the refrigerator 100 shown in fig. 2 when they are coupled. The refrigerator 100 of the embodiment of the present invention may generally include: the drawer comprises a box body 110, a first drawer 200, a second drawer 300, a first door body 121, a second door body 122 and at least one linkage mechanism 400. A storage compartment is defined in the cabinet 110 of the refrigerator 100. The quantity and the structure of storing compartment can dispose according to the demand. For example, fig. 1 shows a case where a first storage compartment and a second storage compartment are provided in this order from top to bottom. The first door 121 disposed at the front side of the first storage compartment is a rotary opening door, and is disposed on the front surface of the box body 110 to close the storage compartment. The second door body 122 arranged on the front side of the second storage chamber is a pull-type door, a double-layer drawer is arranged in the second storage chamber and comprises a first drawer 200 positioned below and a second drawer 300 positioned above the first drawer 200, the first drawer 200 is connected with the second door body 122, and the first drawer 200 is driven by the second door body 122 to move back and forth. The storage chamber can be configured into a refrigerating chamber, a freezing chamber, a temperature changing chamber or a fresh-keeping chamber according to different purposes. Each storage compartment can be divided into a plurality of storage areas by a partition plate, and the articles are stored by racks or drawers. For example, the first storage compartment of the refrigerator 100 according to the embodiment of the present invention may be the refrigerating compartment 111, the second storage compartment may be the freezing compartment 112, and the refrigerating drawer 130 is disposed in the refrigerating compartment 111. Handles may also be provided on the door panels of the refrigerator 100 according to embodiments of the present invention to facilitate a user to open and close the storage compartments of the refrigerator 100.

Further, the refrigerator 100 according to the embodiment of the present invention has the first protrusion 251 and the second protrusion 252 spaced apart from each other on the left sidewall 203 and/or the right sidewall 204 of the first drawer 200, the linkage mechanism 400 is configured to have the fixed portion 401 connected to the second drawer 300 and the movable portion 402 rotatably connected to the fixed portion 401, and the relationship between the protrusion 420 of the movable portion 402 and the first protrusion 251 and the second protrusion 252 is changed by controlling the positional relationship between the movable portion 402 and the fixed portion 401, so that the linked/non-linked state of the first drawer 200 and the second drawer 300 is switched.

Further, the linkage mechanism 400 of the refrigerator 100 according to the embodiment of the present invention utilizes the change of the matching relationship between the fixing portion 401, the first fastening portion 421 and the second fastening portion 422 and the first connecting portion 331, the second connecting portion 332 and the third connecting portion 333 of the second drawer 300 to make the linkage mechanism 400 stably fixed no matter in the linkage/non-linkage state; the movable part 402 and the second drawer 300 are fixed by clamping, so that the linkage/non-linkage state is conveniently switched; the fixing part 401 is used to keep the linkage mechanism 400 connected with the second drawer 300 all the time, so that the problems of loss and the like can be avoided.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
