FIG. 8 is a schematic view of the hinge, hover structure and first bezel of the present application in a to-be-assembled state; FIG. 9 is an enlarged schematic view of area B of FIG. 8; FIG. 10 is a schematic view of the hinge, hover structure and first bezel of the present application in an assembled state; fig. 11 is an enlarged schematic view of the region C in fig. 10.

As shown in fig. 8 to 11, the hovering structure 300 is first assembled in the accommodating portion 126 of the first frame 121, where the mounting plate 301 of the hovering structure 300 enters the first opening 127, two ends of the mounting plate 301 are supported by supporting structures 1261 and 1262 located at the top of the accommodating portion 126 (or the hollow structure), so that the hovering structure 300 is positioned in the accommodating portion 126, the supporting structures 1261 and 1262 may be bumps provided in the hollow structure or be top ends of at least one side wall of the hollow structure, and in order to increase the bonding strength between the hovering structure 300 and the first frame 121, the mounting plate 301 and the first frame 121 may be further fixed by means of screw locking or the like; the hover body 302 and the elastic expansion assembly of the hover structure 300 are received in the receiving space of the receiving portion 126 (or hollow structure), and the protrusion 304 of the elastic expansion assembly protrudes at least partially from the second opening 128.

The second connection portion 202 of the hinge 200 is assembled onto the first frame 121, the hinge shaft 203 of the second connection portion 202 enters the pivot hole 125, the second connection portion 202 at least partially covers the mounting plate 301, the second connection portion 202 is fixedly connected into the concave portion of the first frame 121, wherein the limit groove 204 on the hinge shaft 203 is opposite to the convex portion 304 of the hovering structure 300, and the convex portion 304 at least partially enters the limit groove 204 (as shown in fig. 11). The door 120 can hover through the combined action of the limiting groove 204, the protruding portion 304 and the elastic member 306. Specifically, during the rotation of the door 120 around the hinge axis 203, the hovering structure 300 moves along the same path relative to the hinge axis 203, when the elastic telescopic component moves to the limit groove 204, the elastic component 306 changes from the compressed state to the extended state, the protrusion 304 is pushed into the limit groove 204, that is, the protrusion 34 is snapped into the limit groove 204, so as to generate a rotation resistance, the door 120 hovers and cannot be automatically closed, and when the door 120 rotates again, the door 120 needs to be rotated against the resistance, so that the door 120 cannot be automatically closed. When the refrigerator door continues to move against the resistance force due to the external force, the limit groove 204 presses the protrusion 304, so that the elastic piece 306 is compressed, the protrusion 304 is withdrawn from the limit groove 204, and the door 120 continues to move. When the door 120 continues to move, the protrusion 304 of the hovering structure 300 enters the other limit groove of the hinge shaft 203, and the resistance formed by the protrusion 304 and the other limit groove makes the door 120 hovered at the other opening angle and unable to be closed automatically.

With continued reference to fig. 5, in the present embodiment, the limiting groove 204 is a V-shaped groove, and the V-shaped groove is a continuous strip-shaped groove, and the continuous strip-shaped groove is disposed along an axis direction parallel to the hinge shaft 203. It should be noted that the shape and number of the limiting grooves 204 are not particularly limited in the present application, for example, the number of the limiting grooves 204 on the hinge shaft 203 is greater than or equal to one, and the limiting grooves 204 may be concave arc grooves.

In summary, the application provides a refrigerator door with a first frame provided with a containing part for containing a hovering structure, which improves the assembly convenience of the hovering structure of the refrigerator door.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present application, and they are not intended to limit the scope of the present application, and all equivalent embodiments or modifications that do not depart from the spirit of the present application should be included in the scope of the present application.
