The air inside is discharged to realize ventilation in the box body 11, and the air is discharged from the ventilation hole 42 through the activated carbon filter 41, filtered and purified by it before being discharged into the room, thereby preventing the spread of odor and bacteria in the refrigerator into the room; and when the door 12 is rotated and closed, the connecting shaft 1b rotates in the opposite direction and drives the rotating shaft 3d to rotate in the opposite direction. At this time, the winding wheel 48 rotates in the opposite direction to unwind the winding rope 47, and at the same time, the sealing insulation board 44 moves and resets under the reset elastic force of the second spring 46, and gradually seals the ventilation hole 42.
