In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; the specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 4 and 5, the air-cooled refrigerator provided by the embodiment of the invention includes a storage compartment, a first storage drawer 1 and a second storage drawer 2 are arranged in the storage compartment, a partition plate 3 is arranged between the first storage drawer 1 and the second storage drawer 2, drawer guide rails 31 are respectively arranged on two sides of the partition plate 3, a first return air cavity 11 is arranged below the first storage drawer 1, a second return air cavity 21 is arranged below the second storage drawer 2, the first return air cavity 11 or the second return air cavity 21 is communicated with a return air channel of the refrigerator, a vent hole 32 is formed in the partition plate 3, and the first return air cavity 11 is communicated with the second return air cavity 21 through the vent hole 32.

According to the air-cooled refrigerator provided by the embodiment of the invention, as the partition plate 3 is provided with the vent hole 32, the vent hole 32 communicates the first return air cavity 11 with the second return air cavity 21, return air can flow between the first return air cavity 11 and the second return air cavity 21 through the vent hole 32, and if the first return air cavity 11 is communicated with a return air channel of the refrigerator, air in the second return air cavity 21 can flow into the first return air cavity 11 through the vent hole 32 and then enter the return air channel of the refrigerator; if the second air return cavity 21 is communicated with the refrigerator air return channel, the air in the first air return cavity 11 can flow into the second air return cavity 21 through the vent hole 32 and then enter the refrigerator air return channel; therefore, the air return speed is increased, the heat exchange frequency is increased, the storage compartment, the first storage drawer 1 and the second storage drawer 2 can be rapidly cooled, and the energy-saving effect is achieved.

As shown in fig. 6, a return air inlet 4 is formed in a position of the return air channel corresponding to one of the return air chambers, and a space 5 for arranging a connection terminal is formed in a position of the return air channel corresponding to the other return air chamber. Because first return air chamber 11 and second return air chamber 21 are through ventilation hole 32 intercommunication, consequently only need set up a return air inlet and can satisfy the return air requirement, can save the air flue space and arrange binding post.

Among them, there may be one or more ventilation holes 32, and in order to increase the ventilation range, it is preferable to provide a plurality of ventilation holes 32, as shown in fig. 5 and 7, and a plurality of the ventilation holes 32 are arranged in the drawing direction of the first storage drawer 1. Therefore, the plurality of vent holes 32 in the partition plate 3 can increase the ventilation range and further improve the air return efficiency. Preferably, a plurality of the vent holes 32 may be uniformly arranged to make the wind speed uniform, thereby preventing local turbulence of the wind on both sides of the partition 3.

Since the partition plate 3 is a visible part, the vent holes 32 may be shaped for aesthetic reasons, for example, the vent holes 32 may be shaped like a flower as shown in fig. 5, that is, one vent hole 32 is composed of a plurality of small holes arranged circumferentially, thereby not only beautifying the appearance, but also making the ventilation more dispersed and more uniform.

In order to facilitate cleaning of the vent 32, it is preferable that the partition 3 is detachably connected to the inner container of the storage compartment, so that when the vent 32 is clogged or frozen, the partition 3 can be detached to clean the vent 32 for convenient operation.

As shown in fig. 5, in order to limit the position of the partition board 3 and prevent the partition board 3 from swinging, a first positioning structure 33 may be disposed at the bottom of the partition board 3, and a second positioning structure (not shown) may be disposed at the bottom of the liner, where the first positioning structure 33 cooperates with the second positioning structure to prevent the partition board 3 from moving and rotating horizontally relative to the liner.

Specifically, the first positioning structure 33 is a positioning column, the second positioning structure is a positioning groove, and the positioning column is matched with and extends into the positioning groove; or the first positioning structure 33 is a positioning groove, the second positioning structure is a positioning column, and the positioning column is matched with and extends into the positioning groove. From this, when installing baffle 3, can from top to bottom pack into baffle 3 to the direction that is close to the bottom surface of inner bag, make the reference column cooperation stretch into in the constant head tank, when dismantling dress baffle 3, lift up baffle 3, make reference column and constant head tank can, this structure installation and dismantlement convenient operation.

Preferably, the number of the first positioning structures 33 is multiple, the number of the second positioning structures is multiple, and the first positioning structures 33 and the second positioning structures are matched in a one-to-one correspondence manner. Therefore, the partition plate 3 can be limited in multiple points, and the partition plate 3 can be fixed more stably.

Specifically, when the number of the first positioning structures 33 is two, the connection line of two first positioning structures 33 and the drawing direction of the first storage drawer 1 form an included angle, that is, the connection line of two adjacent first positioning structures 33 is not parallel to the length direction of the partition board 3, and when the number of the first positioning structures 33 is three or more, the connection line of a plurality of first positioning structures 33 is a broken line. Thereby, the separators 3 can be prevented from rolling over.

Alternatively, the storage compartment may be a refrigerating compartment, and the set temperature of the first storage drawer 1 is different from the set temperature of the second storage drawer 2. The first storage drawer 1 may be a temperature-variable drawer room, and the second storage drawer 2 may be a premium drawer.

In order to independently control the temperatures of the first storage drawer 1 and the second storage drawer 2, as shown in fig. 6, an air inlet duct 5 is arranged in the refrigerating chamber, the air inlet duct 5 corresponds to the first storage drawer 1 and is provided with a first air inlet 51, the air inlet duct 5 corresponds to the second storage drawer 2 and is provided with a second air inlet 52, the first air inlet 51 is correspondingly provided with a first air door 61, and the second air inlet 52 is correspondingly provided with a second air door 62. Therefore, the temperature of the first and second storage drawers 1 and 2 can be independently adjusted by controlling the opening and closing of the first and

second dampers

61 and 62, thereby achieving the purpose of accurate temperature control.
