Referring to fig. 1 to 6, a refrigerator 100 according to an embodiment of the present invention is schematically illustrated.

The refrigerator 100 includes a cabinet 10, a door 20 to open and close the cabinet 10, and a hinge assembly 30 to connect the cabinet 10 and the door 20.

The case 10 includes a receiving chamber S and a pivoting side P to which the hinge assembly 30 is coupled.

Here, the "pivoting side P" is defined as a region where the door body 20 rotates with respect to the case body 10, i.e., a region where the hinge assembly 30 is provided, a direction of the pivoting side P toward the receiving chamber S is defined as a first direction X, and a direction of the receiving chamber S toward the pivoting side P is defined as a second direction Y.

Specifically, when the hinge assemblies 30 are disposed on both left and right sides of the refrigerator 100, the case 10 includes a left pivoting side P1 and a right pivoting side P2, and when the pivoting side P is the left pivoting side P1, the first direction X is a left-to-right direction, the second direction Y is a right-to-left direction, and when the pivoting side P is the right pivoting side P2, the first direction X is a right-to-left direction, the second direction Y is a left-to-right direction, that is, the actual directions of the first direction X and the second direction Y are different corresponding to the different pivoting sides P, and the following description takes the pivoting side P as the left pivoting side P1 as an example.

Referring to fig. 3, when the door 20 is in the process of being opened from the closed state to the first opening angle α1, the hinge assembly 30 drives the door 20 to rotate in place with respect to the cabinet 10.

Here, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the door 20 rotates in place relative to the case 10, that is, the door 20 rotates only without generating displacement in other directions, so that it is possible to effectively avoid that the door 20 cannot be normally opened due to displacement in a certain direction of the door 20, which will be described with reference to the following specific examples.

Referring to fig. 4, when the door 20 is in the process of being continuously opened from the first opening angle α1 to the second opening angle α2, the hinge assembly 30 drives the door 20 to move from the pivoting side P toward the receiving chamber S.

Here, when the door 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the door 20 moves toward the side of the accommodating chamber S, that is, the door 20 rotates relative to the case 10 and displaces relative to the case 10 along the first direction X, so that the distance that the door 20 protrudes from the case 10 toward the side away from the accommodating chamber S during rotation is greatly reduced, that is, the displacement of the door 20 along the first direction X counteracts the portion that protrudes from the case 10 along the second direction Y during rotation of the door 20, thereby avoiding interference between the door 20 and the peripheral cabinet or wall during opening, and being suitable for use in a scene with a small space of the embedded cabinet or accommodating refrigerator 100.

Referring to fig. 5, when the door 20 is in the process of continuing to open from the second opening angle α2 to the third opening angle α3, the hinge assembly 30 drives the door 20 to move from the receiving chamber S toward the pivoting side P.

Here, when the door 20 is in the process of continuing to open from the second opening angle α2 to the third opening angle α3, the door 20 moves toward the pivoting side P, that is, the door 20 rotates relative to the case 10 and moves relative to the case 10 along the second direction Y, so that the door 20 is far away from the case 10 as far as possible, the opening of the case 10 is ensured, and the problem that drawers, racks, and the like in the case 10 cannot be opened due to interference of the door 20 is avoided.

Referring to fig. 6, when the door 20 is in the process of being continuously opened from the third opening angle α3 to the maximum opening angle α4, the hinge assembly 30 drives the door 20 to rotate in place with respect to the cabinet 10.

Referring to fig. 3, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the hinge assembly 30 drives the door 20 to pivot relative to the case 10 to drive the first engaging portion 21 to disengage from the second engaging portion 11.

Here, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the door 20 rotates in place relative to the case 10, that is, the door 20 only rotates without generating displacement in other directions, so that the phenomenon that the first mating portion 21 cannot be separated from the second mating portion 11 due to displacement in a certain direction of the door 20 can be effectively avoided.

Here, when the projection 21 is completely separated from the groove 11, the first folding angle β is preferably kept less than 90 degrees, avoiding the vertical beam 40 from affecting the opening and closing of the second door 202.

It should be noted that, because the protruding block 21 and the groove 11 are in arc fit, when the door body 20 is in the closed state, in the first direction X or the second direction Y, the protruding block 21 and the groove 11 are mutually limited, and if the door body 20 is displaced along the first direction X or the second direction Y during the process of opening the door body 20 to the first opening angle α1 at this time, the protruding block 21 and the groove 11 will interfere with each other and be blocked, so that the protruding block 21 cannot be separated from the groove 11, and the door body 20 cannot be opened.

In this embodiment, the door 20 rotates in place relative to the case 10 in the process of opening the door 20 to the first opening angle α1, so as to ensure that the door 20 cannot be displaced along the first direction X or the second direction Y in this process, and further ensure that the protrusion 21 can be smoothly separated from the groove 11.

Here, the first opening angle is not greater than 10 °, that is, the protrusion 21 may not be limited by the groove 11 during the opening of the door 20 to about 10 °, and at this time, the protrusion 21 may be completely separated from the groove 11, or the protrusion 21 may not interfere with the groove 11 even if being displaced in the first direction X or the second direction Y.

In addition, if the outer side 12 and the side wall 23 are flush when the door 20 is in the closed state, the side edge 24 protrudes beyond the outer side 12 in the second direction Y during rotation (the protruding distance is generally not more than 3 mm).

Referring to fig. 19 and 20, when the door 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the second shaft 312 moves in the second section L2 to drive the first shaft 311 to move from the initial position A1 to the first stop position A2, and at this time, the door 20 moves from the accommodating chamber S toward the pivot side P to avoid interference with the surrounding cabinet or wall during the opening process of the door 20.

Specifically, the vertical beam 40 and the first door 201 are kept relatively still, that is, the vertical beam 40 and the first door 201 are kept at the first folding angle β, at this time, when the first door 201 is closed again, the bump 21 is inserted into the groove 11 through the notch 111 of the groove 11 and moves along the extending track of the groove 11, so as to drive the vertical beam 40 to gradually rotate to the fully unfolded state, that is, at this time, the vertical beam 40 is simultaneously attached to the inner side surfaces of the first door 201 and the second door 202.

In addition, the side edges 24 move to the side of the outer side 12 adjacent to the accommodating chamber S, that is, the hinge assembly 30 drives the side edges 24 to move toward the side adjacent to the accommodating chamber S, so that interference with surrounding cabinets or walls, etc. caused by protruding of the side edges 24 out of the outer side 12 during the opening of the door 20 can be avoided.

Here, in order to secure the opening degree of the case 10 as much as possible, the problem that the drawer, the rack, etc. in the case 10 cannot be opened due to interference of the door 20 is avoided, the side edge 24 moves to the side close to the accommodating chamber S to the plane in which the outer side 12 is located, and after that, the hinge assembly 30 drives the side edge 24 to move in the plane and gradually approach the accommodating chamber S.

That is, in this case, the side edges 24 are made as close to the outer side surfaces 12 as possible on the basis of ensuring that the side edges 24 do not protrude from the corresponding outer side surfaces 12, so that interference between the door body 20 and peripheral cabinets or walls and the like during the opening process can be avoided, and the opening degree of the case 10 can be ensured as much as possible.

Referring to fig. 21 and 22, when the door 20 is in the process of continuing to open from the second opening angle α2 to the third opening angle α3, the second shaft 312 moves in the third section L3 to drive the first shaft 311 to move from the first stop position A2 to the second stop position A3, and at this time, the door 20 moves from the accommodating chamber S toward the pivot side P to avoid the door 20 from obstructing the opening of the drawers, racks, etc. in the case 10.

Specifically, the vertical beam 40 remains relatively stationary with the first door 201.

In addition, the lateral edges 24 move in the plane of the lateral surface 12 and gradually approach the containing chamber S.

It will be appreciated that when the door 20 is in the process of continuing to open from the second opening angle α2 to the third opening angle α3, if the door 20 rotates in place relative to the case 10, the side edges 24 gradually move toward the side close to the accommodating chamber S, and at the same time, the door 20 gradually moves close to the accommodating chamber S, and the door 20 hinders the opening of the drawers, racks, etc. in the case 10, i.e. reduces the opening of the case 10.

The hinge assembly 30 of the present embodiment drives the side edge 24 to move in the plane of the outer side 12, so that the door 20 can be kept away from the box 10 as far as possible, the opening of the box 10 is ensured, the problem that the drawer, rack and the like in the box 10 cannot be opened due to interference of the door 20 is avoided, and the side edge 24 can be prevented from protruding out of the outer side 12 in a direction away from the accommodating chamber S.

Referring to fig. 23 and 24, when the door 20 is in the process of continuing to open from the third opening angle α3 to the maximum opening angle α4, the first shaft 311 is maintained at the second stop position A3, and the second shaft 312 moves in the fourth section L4 with the first shaft 311 as a center.

At this time, the side edge 24 is always located on the side of the outer side 12 close to the accommodation chamber S.

Here, the second opening angle is not greater than 90 °, the third opening angle is 90 °, and the maximum opening angle is greater than 90 °, that is, in the process of opening the door body 20 to 90 °, the door body 20 is displaced along the first direction X, so as to avoid interference between the door body 20 and the peripheral cabinet or wall body in the opening process, and the rear door body 20 is displaced along the second direction Y, so that the door body 20 is prevented from obstructing the opening of the drawer, the rack, and the like in the case 10, and after reaching 90 °, the door body 20 is rotated in place relative to the case 10 to further open the door body 20.

It will be appreciated that, when the door 20 is opened from the closed state to the first opening angle α1, the door 20 slightly protrudes from the case 10 toward the side (left side) away from the accommodating chamber S due to the in-situ rotation of the door 20 relative to the case 10, and when the door 20 is continuously opened from the first opening angle α1 to the second opening angle α2, the displacement of the door 20 in the first direction X can offset all the parts of the door 20 protruding from the case 10 in the second direction Y during the whole rotation, and then when the door 20 is continuously opened from the second opening angle α2 to the third opening angle α3, the displacement of the door 20 in the second direction Y can prevent the door 20 from protruding from the case 10 and ensure the opening of the case 10 as much as possible.

In other embodiments, the first slot 321 further includes a pivot position A4 located at a side of the second stop position A3 away from the initial position A1, and the second slot 322 further includes a transition section L located between the third section L3 and the fourth section L4, where a line connecting the second stop position A3 and the pivot position A4 is parallel to the transition section L.
