When the lifting button 150 is pressed, the driving device 422 drives the telescopic rod 421 to move from the original position to the door opening position, so as to achieve the purpose of lifting the shelf assembly 300; when the lowering button 160 is pressed, the driving means 422 drives the telescopic bar 421 to move from the door opening position to the original position, so as to achieve the purpose of lowering the shelf assembly 300.

To sum up, the utility model provides a freezer compares with prior art, includes following beneficial effect at least:

firstly, the method comprises the following steps: the shelf assembly 300 of the refrigerator is used for bearing articles stored in the refrigerator, when the lifting assembly 400 drives the shelf assembly 300 to ascend, the door pushing portion 511 of the door opening assembly 500 on the shelf assembly 300 pushes the door body 200 to rotate upwards so as to open the first opening 131, so that a user does not need to spend effort on opening the door body 200 when the refrigerator stores and takes articles, and manpower is saved; and because the high rising of layer frame subassembly 300, the height of the article that layer frame subassembly 300 bore is also along with rising for the article that layer frame subassembly 300 bore more is close to first opening 131, and convenience of customers gets from the freezer and puts article, then the user need not to bend down by a wide margin and takes or put into article, makes the freezer use more convenient, promotes user's use and experiences.

Secondly, the method comprises the following steps: inner bag 120 passes through bleeder vent 121 intercommunication compressor storehouse 140, drive arrangement 422 sets up in compressor storehouse 140, telescopic link 421 passes bleeder vent 121, then telescopic link 421 can make sealing member 423 open bleeder vent 121 when opening the door, the inside and exterior space's of balanced inner bag 120 atmospheric pressure, it leads to opening the unsmooth phenomenon emergence of door to reduce the interior refrigeration negative pressure of cabinet, in order to make things convenient for push-off door portion 511 to up promote door body 200, make things convenient for push-off door portion 511 to open door body 200, reducible electric putter's maximum output power, energy saving, and energy consumption is reduced.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
