The electromagnet 530 is energized to attract the position-limiting post 540, the position-limiting post 540 is moved upward to be separated from the position-limiting hole 322, and the cover plate 320 rotates around the lower end of the cover plate 320 under the action of its own weight and the objects contained therein. The articles in the storage box 300 slide out of the storage box 300 on the rollers 330 under the self-gravity. The goods begin to thaw. The articles in the storage boxes 300 start to be defrosted in sequence according to set time, so that a user does not need to wait during use, the user can use the articles conveniently, the defrosting time is saved, and the defrosting efficiency is improved.

In this application, put storage box subassembly 20 in the cold-stored compartment 10 of refrigerator, the refrigeration wind channel directly communicates with storage box subassembly 20 in order to carry cold volume, and a plurality of article of difference holding are stored in a plurality of storage boxes 300 to freezing a plurality of article and store. When the articles need to be defrosted for use, the air supply pipe 400 is cut off by the air door 420, so that the corresponding storage box 300 is not communicated with the refrigeration air duct. The air door 420 that a plurality of storage box subassembly 20 correspond can be closed according to a plurality of time points that set up in advance in proper order to storage box subassembly 20, cuts off cold volume and carries, opens corresponding apron 320 simultaneously, makes the article that corresponds in the storage box 300 expose under the temperature of cold-stored room, changes article automatically and freezes to be convenient for the user uses, practices thrift and changes the time of freezing, improves and changes and freezes efficiency.

While the present application has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present application may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
