When the storage drawer 120 is closed, the fifth attraction piece 163 is attracted to the fifth magnetic piece 153, so that the fourth elastic airbag 152 is stretched, and the first shielding portion 123 and the second shielding portion 111a are tightly sealed, so that the space between the transverse side wall of the storage drawer 120 and the transverse side wall of the storage liner 111 located on the same side is sealed, and meanwhile, the fifth attraction piece 163 is prevented from being attracted to the fifth magnetic piece 153, and the use experience of a user is improved. As shown in fig. 10, a fifth suction element 163 is attached to the rear side of the first shielding portion 123, a fourth elastic airbag 152 is disposed at the front side of the second shielding portion 111a, and the fourth elastic airbag 152 can be disposed at the front side of the second shielding portion 111a through a fourth fixing element 151, so as to enhance the firmness of the fourth elastic airbag 152, and the fourth elastic airbag 152 can be stretched freely under the action of external force. The fourth fixing member 151 may be attached to the front side of the second shielding portion 111a by a double-sided tape or an adhesive.

In this embodiment, referring to the drawings, the front end of the storage drawer 120 corresponds to the handle of the storage drawer 120, and the handle of the storage drawer 120 provides a location for the magnetic member or the attraction member. In the foregoing embodiment, the magnetic force between the elastic airbag, the magnetic member, and the absorbing member is used to seal the gap between the front end portion of the storage drawer 120 and the gap between the lateral side portion of the storage drawer 120 and the door body 117, so that the refrigerator 100 has the advantages of simple structure, smart design, and low cost, and the energy consumption of the refrigerator 100 is greatly reduced with little increase in cost.

Each of the magnetic members may be a magnetic material such as a magnet, and each of the attraction members may be a metal, such as an iron bar, that generates attraction force with the magnetic material, or may be a magnetic material such as a magnet.

To ensure that the return air in the storage space can flow back to the evaporator 112 for cooling, in this embodiment, a bottom return air inlet 122 is formed in the bottom wall of each storage drawer 120 near the front end, and/or a side return air inlet 121 is formed in at least one lateral side wall of each storage drawer 120 near the front end, and the return air in the storage space flows back to the evaporator 112 through the bottom return air inlet 122 and/or the side return air inlet 121 for cooling again, thereby ensuring the circulation of the air flow between the evaporator 112 and the storage space. As shown in fig. 2, a bottom air return opening 122 is formed in a bottom wall of the storage drawer 120 near the front end, and a side air return opening 121 is formed in a lateral side wall of the storage drawer 120 near the front end. It can be understood by those skilled in the art that the positions of the bottom air return opening 122 and the side air return opening 121 are both located behind the corresponding elastic airbags, and should also be located behind the corresponding second shielding portion 111a, so as to ensure that the return air can enter the bottom air return opening 122 and the side air return opening 121 and flow out of the storage space.

In this embodiment, the storage liner 111 may be a freezing liner, and accordingly, the storage space is a freezing space, the temperature difference between the temperature in the freezing space and the external environment of the refrigerator 100 is larger, and the problem of the heat load caused by heat leakage of the door body 117 is more prominent.
