here, it can be understood that when the inclined convex part 122 applies a force toward the door body 2 from the second limiting surface, the sliding block 81 can be made to horizontally slide along the first and second sliding grooves 83; when the inclined protrusion 122 exerts a force away from the door body 2 from the second guide surface, the latching block 812 can be retracted into the opening 813, so that the inclined protrusion 122 can smoothly move from the direction behind the sliding block 81 to the direction in front of the sliding block 81.
Preferably, the places where the door seal 10 contacts with the protruding parts 30 are all provided with dents, and the places where the protruding parts 30 contact with the door seal 10 are all provided with dents; of course, if the portions of the door seal 10 contacting the door body 2 are rough, the friction between the door seal 10 and the door body 2 can be greatly increased, and the purpose of the present invention can also be achieved.
In summary, the invention provides a refrigerator 100, wherein an air pipe 20 is embedded in a door seal 10 fixed at the front side of the outer edge of a refrigerator body 1, the adjustment of the sealing degree between a door body 2 and the refrigerator body 1 is realized by simply controlling the air exhaust and the inflation of the air pipe 20, when the door body 2 is closed, the driving device 3 drives the air pipe 20 to inflate to enable the door seal 10 to seal the refrigerator 100, so that the door body 2 is tightly attached to the refrigerator body 1, thereby reducing the loss of cooling capacity and reducing the energy consumption; when the door body 2 is pulled, the driving device 3 drives the air pipe 20 to exhaust air so as to eliminate the friction force between the door seal 10 and the box body 1, so that a user can open the door body 2 easily, the structure is simple, and the use feeling is improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
