1. A refrigerator, comprising:
a refrigerator body; and
a door body rotatably connected to the refrigerator body, the door body being rotatably supported by a hinge located at an upper end of the door body and a hinge located at a lower end of the door body, each of the upper and lower ends of the door body being provided with a first trajectory slot and a second trajectory slot, wherein
each of the hinge located at the upper end of the door body and the hinge located at the lower end of the door body includes a hinge plate connected to the refrigerator body, and a first hinge shaft and a second hinge shaft that are connected to the hinge plate to constitute rotation shafts; and the first hinge shaft is matched with the first trajectory slot, and the second hinge shaft is matched with the second trajectory slot;
a hinge plate of the hinge located at the upper end of the door body is connected to an upper end of the refrigerator body, and a hinge plate of the hinge located at the lower end of the door body is connected to a lower end of the refrigerator body; and
the door body includes a front wall and a side wall, and for each of the hinge located at the upper end of the door body and the hinge located at the lower end of the door body, the side wall is a side of a left side and a right side of the door body proximate to the hinge plate, wherein
in a case where the hinge plate is located on a right side of the refrigerator body, the right side of the door body is the side wall; or
in a case where the hinge plate is located on a left side of the refrigerator body, the left side of the door body is the side wall;
wherein for each of the hinge located at the upper end of the door body and the hinge located at the lower end of the door body,
in a case where the door body is in a closed state,
the first hinge shaft is closer to the side wall and farther away from the front wall than the second hinge shaft; and
the first trajectory slot has a first positioning position and a second positioning position, a movement trajectory of the first hinge shaft in the first trajectory slot from the first positioning position to the second positioning position is a first positioning trajectory line; correspondingly, the second trajectory slot has a first guiding position and a second guiding position, a movement trajectory of the second hinge shaft in the second trajectory slot from the first guiding position to the second guiding position is a first guiding trajectory line;
in a case where the door body is opened from the closed state to a first state,
the first hinge shaft moves from the first positioning position to the second positioning position along the first positioning trajectory line with respect to the first trajectory slot; meanwhile, the second hinge shaft moves from the first guiding position to the second guiding position along the first guiding trajectory line with respect to the second trajectory slot;
the second positioning position is farther away from the front wall and closer to the side wall than the first positioning position, and the first positioning trajectory line extends in a direction away from the front wall and proximate to the side wall; the second guiding position is farther away from the front wall and closer to the side wall than the first guiding position, and the first guiding trajectory line extends in a direction away from the front wall and proximate to the side wall; and
the first trajectory slot further has a third positioning position, a movement trajectory of the first hinge shaft in the first trajectory slot from the second positioning position to the third positioning position is a second positioning trajectory line; correspondingly, the second trajectory slot further has a third guiding position, a movement trajectory of the second hinge shaft in the second trajectory slot from the second guiding position to the third guiding position is a second guiding trajectory line;
in a case where the door body continues to be opened from the first state to a second state,
the first hinge shaft moves from the second positioning position to the third positioning position along the second positioning trajectory line with respect to the first trajectory slot, and the second hinge shaft moves from the second guiding position to the third guiding position along the second guiding trajectory line with respect to the second trajectory slot;
the third positioning position is closer to the front wall and the side wall than the second positioning position, and the second positioning trajectory line extends from the second positioning position to the third positioning position in a direction proximate to the front wall and the side wall; the third guiding position is farther away from the front wall and closer to the side wall than the second guiding position, and the second guiding trajectory line extends in a direction away from the front wall and proximate to the side wall; and
an opening angle of the door body in the second state is less than 90°; and
in a case where the door body continues to be opened from the second state to a state with a 90° opening angle,
a position of the first hinge shaft remains unchanged in the first trajectory slot, the door body rotates with the first hinge shaft as a center of a circle, and the second hinge shaft moves to a fourth guiding position along a third guiding trajectory line in the second trajectory slot; the third guiding trajectory line is in a shape of an arc, and the fourth guiding position is farther from the front wall and closer to the side wall than the third guiding position.
