The number of the sub-grooves, the sequence of the sub-grooves, the extending direction, the shape, the length and other parameters can be designed according to the required preset track of the door body 2.

Further, when the sub-grooves are arc-shaped grooves, the arc-shaped grooves can be elliptical arc-shaped grooves or arc-shaped grooves, and can be designed according to the preset track requirement of the door body 2.

Further, when the sub-grooves are arc-shaped grooves, the bending direction of the arc-shaped grooves can be set to be bent towards the direction away from the side edges 23, or can also be set to be bent towards the side edges 23, and the sub-grooves can be designed according to the preset track requirement of the door body 2.

It is understood that the above-mentioned bending in the direction away from the side edge 23 and the bending in the direction toward the side edge 23 refer to the bending direction of the arc-shaped groove with the side edge 23 as a reference.

The subslot has opposite head and tail ends. The extension direction of the subslot is defined herein as the extension direction of the line connecting the head end and the tail end of the subslot. The extending direction of any one of the sub-grooves in the hinge groove 321 may be selected from one of the following four extending directions (extending direction a, extending direction B, extending direction C, and extending direction D):

extension direction a: when the door body 2 is in a closed state, a connecting line between the head end and the tail end of the subslot extends along the first direction. That is, at least one of the subslots constituting the hinge slot 321 is formed to extend in the first direction. When the hinge slot 321 is composed of at least two subslots, at least one subslot extends along the first direction, and the extending directions of the other subslots are not limited. When the subslot is a linear slot, it means that the subslot is a linear slot extending in the first direction. When the sub-slot is an arc-shaped slot, it means that the sub-slot is an arc-shaped slot extending and bending along the first direction.

The extending direction B: when the door body 2 is in a closed state, a connecting line between the head end and the tail end of at least one subslot extends along the second direction. That is, at least one of the subslots constituting the hinge slot 321 is formed to extend in the second direction. When the hinge slot 321 is composed of at least two subslots, at least one subslot extends along the second direction, and the extending directions of the other subslots are not limited. When the subslot is a linear slot, it means that the subslot is a linear slot extending in the second direction, i.e., a horizontal slot. When the sub-slot is an arc-shaped slot, it means that the sub-slot is an arc-shaped slot extending and bending along the second direction.

The extending direction C: when the door body 2 is in a closed state, a connecting line between a head end and a tail end of at least one subslot extends obliquely toward the box body 1 and toward the pivoting side 10 in a direction toward the box body 1. That is, when the pivoting side 10 is the right side, the line connecting the head end and the tail end of the sub-groove extends obliquely rearward and rightward in the direction toward the box body 1, when the sub-groove is a straight-line groove, the sub-groove extends obliquely rearward and rightward, and when the sub-groove is an arc-shaped groove, the sub-groove is an arc-shaped groove which extends obliquely rearward and rightward and is curved. When the pivoting side 10 is the left side, along the direction toward the box body 1, the line connecting the head end and the tail end of the sub-slot extends obliquely backward and leftward, when the sub-slot is a linear slot, the sub-slot extends obliquely backward and leftward, and when the sub-slot is an arc-shaped slot, the sub-slot is an arc-shaped slot which extends obliquely backward and leftward and is curved.

Extension direction D: when the door body 2 is in a closed state, along the direction toward the box body 1, a connecting line between the head end and the tail end of at least one subslot extends obliquely toward the box body 1 and in a direction away from the pivoting side 10. That is, when the pivoting side 10 is the right side, the line connecting the head end and the tail end of the sub-groove extends obliquely rearward and leftward in the direction toward the box body 1, when the sub-groove is a straight-line groove, it means that the sub-groove extends obliquely rearward and leftward, and when the sub-groove is an arc-shaped groove, it means that the sub-groove is an arc-shaped groove extending obliquely rearward and leftward and curved.

The number of the sub-grooves in the hinge groove 321, the shape of each sub-groove, the extending direction of each sub-groove, the inclination angle, and the like can be arbitrarily combined according to the preset track requirement of the door body 2. The shape of the sub-groove includes a linear groove and an arc groove, the arc groove is divided into an elliptical arc groove and an arc groove, and meanwhile, with the side edge 23 as a reference, the bending direction of the arc groove is divided into a direction bending away from the side edge 23 and a direction bending toward the side edge 23.

It is known that when the hinge slot 321 is composed of only one section of the subslot, the end of the hinge slot 321 refers to the head end and the tail end of the subslot. When the hinge slot 321 is composed of a plurality of sections of the subslots, the adjacent head ends and tail ends of the two sections of the subslots are connected to form the hinge slot 321, and at this time, the end of the hinge slot 321 refers to the head end or tail end of the subslot located at the end.

Meanwhile, the shape, extending direction, length, etc. of the guide groove 322 may be designed according to the corresponding hinge groove 321.

Next, various embodiments regarding the hinge slot 321 will be described.

In the first embodiment, as shown in fig. 1 to 3, the refrigerator 100 includes a hinge assembly 3, the hinge groove 321 of the hinge assembly 3 is composed of only one segment of sub-groove, and the sub-groove is a linear groove. When the door body 2 is in a closed state, the hinge groove 321 extends along the second direction, that is, the hinge groove 321 is a linear groove extending along the transverse direction of the door body 2.

The hinge slot 321 has a first end L1 away from the pivoting side 10 and a second end L2 close to the pivoting side 10. The guiding groove 322 has an initial position P1, a terminal position P2, and a first groove section P3 extending from the initial position P1 to the terminal position P2. When the door 2 is in a closed state, the guide shaft 312 is located at the initial position P1, and the hinge shaft 311 is located at the first end L1. In the process that the door 2 is rotated to open from the closed state to the first opening angle, the guide shaft 312 moves along the first slot segment P3 toward the terminal position P2, and guides the hinge shaft 311 to move along the hinge slot 321 from the first end L1 to the second end L2, and the translation direction of the door 2 has components in the fourth direction D2 and the fifth direction D3, that is, the door 2 translates forward and away from the cabinet located on the pivoting side 10, so that interference between the cabinet and the box 1 in the process that the door 2 is rotated to open can be avoided.

It is known that the first end L1 of the hinge slot 321 refers to the head end of the subslot, and the second end L2 of the hinge slot 321 refers to the tail end of the subslot.

Specifically, when the pivoting side 10 is the right side, in the process that the door body 2 rotates from the closed state to the first opening angle, the door body 2 translates to the left front. When the pivoting side 10 is the left side, the door body 2 translates to the right front side in the process that the door body 2 rotates from the closed state to be opened to the first opening angle.

Further, the first opening angle is smaller than 90 °, it is known that, when the door 2 is opened to 90 °, the included angle between the hinge slot 321 and the box 1 is also 90 °, and before the door 2 is opened to 90 °, the included angle between the hinge slot 321 and the box 1 is also smaller than 90 °, at this time, along the direction away from the box 1, the extending direction of the hinge slot 321 has components in the fourth direction D2 and the fifth direction D3, so that, when the hinge shaft 311 moves toward the second end L2 relative to the hinge slot 321 before the door 2 is rotated to 90 °, the door 2 can be driven to move forward and translate in the direction away from the cabinet located on the pivoting side 10, and interference between the cabinet and the box 1 can be avoided in the process that the door 2 is rotated to open. Of course, this is not a limitation.

Further, the guiding groove 322 further includes a second groove section P4 communicating the first groove section P3 with the terminal position P2; the second groove section P4 is an arc with the second end L2 as a center. In the process that the door body 2 is continuously opened from the first opening angle to the maximum opening angle, the hinge shaft 311 is kept at the second end L2, the guide shaft 312 moves towards the terminal position P2 in the second groove section P4 with the hinge shaft 311 as a circle center, and the door body 2 rotates in situ with the second end L2 as a circle center, so that the opening degree of the door body 2 is increased, and a user can take and place articles conveniently.

In a second embodiment, as shown in fig. 4-8, the hinge slot 321' is composed of only one segment of sub-slot, and the sub-slot is an arc-shaped slot curved toward the side edge 23. Meanwhile, when the door body 2 is in a closed state, a connecting line between the head end and the tail end of the subslot extends along the second direction. That is, the hinge slot 32' is an arc-shaped slot extending in the second direction and curved toward the side edge 23.

Specifically, the arc-shaped groove is an elliptical arc-shaped groove.

Further, the hinge slot 321' has a first section L3' communicating with the first end L1', a second section L4' communicating with an end of the first section L3' far from the first end L1', and a third section L5' communicating with the second section L4' and the second end L2'.
