In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it may be a mechanical connection or an electrical connection, or two The internal communication between the elements may be directly connected or indirectly connected through an intermediate medium, and those of ordinary skill in the art can understand the specific meanings of the above terms according to specific circumstances.

In order to facilitate the description of the mutual positional relationship of different components, in this embodiment of the present invention, when the refrigerator is in normal use, the direction away from the ground is upward, and the direction toward the ground is downward; when the user faces the door, The direction of the refrigerator toward the user is forward, and the direction away from the user is backward; correspondingly, the left and right directions are defined.

As shown in FIGS. 1 to 9 , the present invention proposes a refrigerator 100 . The refrigerator 100 includes an outer box 1 and an inner box 2 nested inside the outer box 1 . The outer box 1 A first opening 10 is opened on one side, and a second opening 20 communicating with the first opening 10 is opened in the inner box 2 to form a closed space with the outer box 1 , and the volume of the closed space can be adjusted by pulling. The inner box 2 changes during the process; when the items that the user needs to store temporarily increase or are large-volume items, the refrigerator 100 realizes the adjustment of the total volume, which meets the needs of the user in different periods;

Here, the inner box 2 may be configured to be pulled on the outer box 1 in the front-rear direction, or may be configured to be pulled on the outer box 1 in the left-right direction, as long as the volume of the closed space is variable. achieve the purpose of the present invention.

At least one door seal 30 is arranged around the outer side of the inner box 2, and the inside of the door seal 30 is hollow. The inner box 2 further includes a spiral coil 40 embedded in the inside of the door seal 30. The refrigerator 100 It also includes a switch 3 for controlling the on-off of the helical coil 40; here, the switch 3 can be of various types, such as electronic or mechanical, as long as the on-off of the helical coil 40 can be controlled, or A display screen electrically connected to the helical coil 40 is provided on the refrigerator 100 to facilitate the user to control the power on and off of the refrigerator 100 more conveniently, and the object of the present invention can be achieved.

When the inner box 2 is in a static state, the helical coil 40 is de-energized and expanded so that the door seal 30 seals the refrigerator 100; when the inner box 2 is in a pulling state, the spiral coil 40 is energized and contracted To eliminate the friction between the door seal 30 and the outer box 1;

Here, as shown in FIG. 9 , the spiral coil 40 can be understood as a series of several circular rings. When the spiral coil 40 is energized, the direction of the current in the adjacent rings is the same. The direction of the formed magnetic field is also the same, so that the adjacent rings will attract each other, causing the entire helical coil 40 to shrink; as shown in FIG. Correspondingly shrunk, so that the door seal 30 changes from the state of close contact with the outer box body 1 to a gap, and then the friction force between the door seal 30 and the outer box body 1 does not exist, which is convenient for users. The inner box 2 can be easily opened, the structure is simple and the sense of use is improved;

When the user needs to close the inner box 2, after pushing the inner box 2 to the closed state, the helical coil 40 is controlled to be powered off, and the helical coil 40 expands so that the door seal 30 is restored to the outer box 1 The tightly fitted state realizes the sealing of the refrigerator 100, thereby reducing the loss of cooling capacity and reducing energy consumption;

Preferably, an accommodating cavity 50 is formed on the outer side of the inner box 2 inwardly, and the switch 3 is disposed in the accommodating cavity 50 and is electrically connected to the helical coil 40 ; the helical coil 40 includes two The terminal 41, the switch 3 includes a toggle member 80 and a contact end 90 electrically connected to the two terminals 41 respectively, and the toggle member 80 is a conductive material;

When the toggle member 80 is in contact with two of the contact ends 90, the helical coil 40 is energized; when the toggle member 80 is toggled in contact with only one contact end 90, the helical coil 40 is energized. power failure;

Here, when the user needs to adjust the volume of the refrigerator 100, he only needs to toggle the toggle member 80 to contact the two contact ends 90, the helical coil 40 is energized and contracted, and then the door seal 30 is connected to the outer box. The friction force between the bodies 1 does not exist, which is convenient for the user to easily pull it apart;

After the volume adjustment is completed, the toggle member 80 is only in contact with one contact end 90, and the helical coil 40 is powered off and expands, so that the door seal 30 returns to the state of close contact with the outer box 1, The sealing of the refrigerator 100 is achieved. The structure is simple, the operation is convenient, and the refrigerator 100 is in a state of being stationary and not being pulled to adjust the volume most of the time, that is, the spiral coil 40 is in a power-off state most of the time, thereby saving energy.

In addition, the inner case 2 includes a support portion 60 , and the support portion 60 is disposed below the side of the inner case 2 away from the second opening 20 to support the pull-out portion of the outer case 1 . The inner box 2.

As shown in FIG. 1 to FIG. 3 , there are two door seals 30 ; the door seal 30 includes a first door seal 3130 surrounding the side away from the second opening 20 and a first door seal 3130 close to the second opening. A second door seal 3230 is arranged around one side of the 20 .

The inner box body 2 further includes at least one groove 70 recessed inward from the outer side wall of the inner box body 2 , and the door seal 30 is fixedly arranged in the groove 70 .
