In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0040] Referring to Figures 1 to 3 The application provides a refrigerator 1, comprising: an inner container 10, an outer shell 11 and a box door 12.

[0041] The inner container 10 is arranged in the outer shell 11, and an inner part of the inner container 10 forms a storage space 101. The inner container 10 further comprises an inner container edge 102 and an opening 103 enclosed by the inner container edge 102, and the opening 103 is in communication with the storage space 101. Exemplarily, the storage space 101 can be a freezing chamber or a refrigerating chamber.

[0042] The box door 12 comprises a door body 121 and a door seal 122. The door body 121 is used to open or close the opening 103, and the door seal 122 is arranged at an edge of the door body 121. Wherein, the inner container edge 102 comprises an edge back surface 1021 opposite to the box door 12. One of the edge back surface 1021 and the door seal 122 is provided with a magnetic attraction piece 13, and the other is provided with a magnetic attraction matching piece 14; when the box door 12 is in a closed state, the magnetic attraction piece 13 and the magnetic attraction matching piece 14 are magnetically attracted and matched. For example, when the edge back surface 1021 is provided with the magnetic attraction piece 13, the door seal 122 is provided with the magnetic attraction matching piece 14. For another example, when the edge back surface 1021 is provided with the magnetic attraction matching piece 14, the door seal 122 is provided with the magnetic attraction piece 13.

[0043] In the above scheme, by arranging the magnetic attraction piece 13 or the magnetic attraction matching piece 14 at the edge back part of the inner container edge 102 opposite to the box door 12, a gap can be avoided as much as possible on the side of the inner container edge 102 facing the box door 12, the box door 12 and the inner container 10 can be tightly fitted, and the cold air leakage can be reduced, and the energy consumption can be reduced.

[0044] Referring to Figure 2 and Figure 3In one embodiment, the inner container 10 further comprises an inner container wall 104, and the inner container edge 102 extends outwardly from the inner container wall 104 and is connected to the outer shell 11. The inner container wall 104, the inner container edge 102 and the outer shell 11 jointly define a heat insulation space 105 for arranging heat insulation material. The rear edge surface 1021 of the inner container edge 102 faces the heat insulation space 105, and the magnetic attraction member 13 or the magnetic attraction matching member 14 is arranged in the heat insulation space 105 and is attached to the rear edge surface 1021. In this way, by extending the inner container edge 102 outwardly from the inner container wall 104, the rear edge surface 1021 of the inner container edge 102 has sufficient space to install the magnetic attraction member 13 or the magnetic attraction matching member 14. In addition, the heat insulation effect of the refrigerator can be further improved by arranging heat insulation material in the heat insulation space 105.

[0045] Of course, in other embodiments, the inner container edge 102 can also be a circumferential edge of the inner container wall 104 facing the opening 103.

[0046] It should be noted that the attachment of the magnetic attraction member 13 or the magnetic attraction matching member 14 can be achieved by existing methods including but not limited to bonding or heat pressing, which will not be described in detail here.

[0047] Please refer to Figure 3 and Figure 4 In one embodiment, the inner container edge 102 further comprises a front edge surface 1022 facing one side of the door 12. The rear edge surface 1021 is recessed to form a mounting groove (not shown in the figure) towards the front edge surface 1022, and at least part of the structure of the magnetic attraction member 13 or the magnetic attraction matching member 14 is embedded in the mounting groove. In this way, the design of the mounting groove can make the front edge surface 1022 protrude towards one side of the door seal 122, increase the matching area with the door seal 122, and further reduce the cold air leakage.

[0048] In one embodiment, the magnetic attraction member 13 or the magnetic attraction matching member 14 is completely embedded in the mounting groove. In this way, the mounting groove neither occupies the heat insulation space 105 nor increases the matching area of the front edge surface 1022 with the door seal 122.

[0049] Of course, in other embodiments, the magnetic attraction member 13 or the magnetic attraction matching member 14 can also be partially embedded in the mounting groove.

[0050] Please continue to refer to Figure 3 and Figure 4In one embodiment, the inner container edge 102 comprises a first portion 102a and a second portion 102b. The first portion 102a extends outwardly from the inner container wall 104, and the second portion 102b extends outwardly from the first portion 102a. The first portion 102a and the second portion 102b are both provided with the magnetic attraction member 13 or the magnetic attraction matching member 14.

[0051] Generally, the door body 121 of the box door 12 comprises a door panel and an inner container provided on the inner side of the door panel. The first portion 102a of the inner container edge 102 is configured to match the inner container, and the second portion 102b of the inner container edge 102 is configured to match the door panel. The magnetic attraction member 13 or the magnetic attraction matching member 14 is provided on both the first portion 102a and the second portion 102b, so that the sealing effect of the box door 12 and the inner container 10 can be further improved by double magnetic attraction matching.

[0052] In one embodiment, the magnetic attraction member 13 comprises a permanent magnet, and the magnetic attraction matching member 14 comprises at least one of a permanent magnet, a metal with a natural magnet structure, a ferromagnetic metal, and an electromagnet. Exemplarily, the permanent magnet comprises but is not limited to a magnet, and the metal with a natural magnet structure comprises but is not limited to iron.

[0053] Please refer to Figure 4 and Figure 5 In one embodiment, the magnetic attraction member 13 or the magnetic attraction matching member 14 comprises a long strip structure extending along the length direction of the inner container edge 102 (i.e., the up-down direction of the inner container edge 102). Figure 5 In this way, the attraction area of the magnetic attraction member 13 or the magnetic attraction matching member 14 can be increased. Exemplarily, the long strip structure can be an integral strip structure extending from one end of the inner container edge 102 to the other end. Of course, in other examples, the long strip structure can also be a plurality of strip structures extending from one end of the inner container edge 102 to the other end and arranged at intervals.

[0054] In one embodiment, the long strip structure is a plate structure, and one side of the plate structure with a larger area is attached to the rear surface 1021 of the inner container edge 102. In this way, the connection stability of the plate structure can be improved, and the attraction area can be increased. In one embodiment, the long strip structure is a plate structure, and the thickness of the plate structure is less than the thickness of the inner container edge 102. In this way, the production cost can be reduced.

[0055] Please refer to Figure 4 and Figure 6In one embodiment, the door seal 122 is internally provided with an air bag 1221, which is located between the door body 121 and the inner container edge 102. The air bag 1221 is internally provided with a mounting space 1222 for mounting the magnetic attraction member 14 or the magnetic attraction piece 13. Thus, after the magnetic attraction member 14 and the magnetic attraction piece 13 are attracted to each other, the air bag 1221 can be deformed by its own elasticity, so as to form a more compact sealing structure between the door seal 122 and the inner container edge 102.

[0056] Please continue to refer to Figure 6 In one embodiment, the shell 11 includes a wrapping structure 111 wrapped around the inner container edge 102. The wrapping structure 111 and the inner container edge 102 are further provided with an auxiliary matching member 15. The door seal 122 further includes an auxiliary attraction member 16 for magnetically matching with the auxiliary matching member 15 or the wrapping structure 111. Thus, the cold leakage can be further reduced.

[0057] Exemplarily, the auxiliary matching member 15 can be a permanent magnet, and the auxiliary attraction member 16 can be at least one of a permanent magnet, a metal having a natural magnet structure, and a ferromagnetic metal, and an electromagnet. Specifically, the permanent magnet includes but is not limited to a magnet, and the metal having a natural magnet structure includes but is not limited to iron. In addition, the shell 11 can be made of at least one of the metal having a natural magnet structure and the ferromagnetic metal.

[0058] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
